kn-title=Utility of Same-Modality, Cross-Domain Transfer Learning for Malignant Bone Tumor Detection on Radiographs: A Multi-Faceted Performance Comparison with a Scratch-Trained Model
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background/Objectives: Developing high-performance artificial intelligence (AI) models for rare diseases like malignant bone tumors is limited by scarce annotated data. This study evaluates same-modality cross-domain transfer learning by comparing an AI model pretrained on chest radiographs with a model trained from scratch for detecting malignant bone tumors on knee radiographs. Methods: Two YOLOv5-based detectors differed only in initialization (transfer vs. scratch). Both were trained/validated on institutional data and tested on an independent external set of 743 radiographs (268 malignant, 475 normal). The primary outcome was AUC; prespecified operating points were high-sensitivity (?0.90), high-specificity (?0.90), and Youden-optimal. Secondary analyses included PR/F1, calibration (Brier, slope), and decision curve analysis (DCA). Results: AUC was similar (YOLO-TL 0.954 [95% CI 0.937?0.970] vs. YOLO-SC 0.961 [0.948?0.973]; DeLong p = 0.53). At the high-sensitivity point (both sensitivity = 0.903), YOLO-TL achieved higher specificity (0.903 vs. 0.867; McNemar p = 0.037) and PPV (0.840 vs. 0.793; bootstrap p = 0.030), reducing ~17 false positives among 475 negatives. At the high-specificity point (~0.902?0.903 for both), YOLO-TL showed higher sensitivity (0.798 vs. 0.764; p = 0.0077). At the Youden-optimal point, sensitivity favored YOLO-TL (0.914 vs. 0.892; p = 0.041) with a non-significant specificity difference. Conclusions: Transfer learning may not improve overall AUC but can enhance practical performance at clinically crucial thresholds. By maintaining high detection rates while reducing false positives, the transfer learning model offers superior clinical utility. Same-modality cross-domain transfer learning is an efficient strategy for developing robust AI systems for rare diseases, supporting tools more readily acceptable in real-world screening workflows.

kn-title=Water Lubrication of Polysiloxane-Containing Polyimide Coatings on Stainless Steel Substrates
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study investigated the water-lubricated tribological properties of coatings made of a novel polysiloxane-containing polyimide (si-PI) material that was recently developed for the aerospace industry and can be diluted with the harmless and environmentally friendly ethanol or water. The si-PI coatings were deposited on stainless steel (JIS SUS304) substrates at curing temperatures ranging from 160°C to 275°C. Their water lubrication properties were measured by rubbing the coatings against each other in water at room temperature. The coatings exhibited lower friction than conventional polyimide materials, with a minimum friction coefficient of 0.04, which was lower than that of polytetrafluoroethylene (PTFE) measured under the same sliding conditions. Unlike the conventional polyimide, the coatings did not exhibit any obvious wear or damage. The results demonstrate that the si-PI coating is a promising low-friction and highly durable coating for water lubrication.

kn-title=Synthesis of thienoacenes by electrochemical double C?S cyclization using a halogen mediator
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Thienoacenes are significant compounds as organic materials. One of the most efficient ways to synthesize thienoacenes is to form multiple C?S bonds in a single step. Because unprotected S?H bonds are easily oxidized to S?S bonds, S-Me protected substrates are commonly used for the purpose. However, their reactivity is insufficient, and one-step construction of multiple C?S bonds is still challenging. We herein report the electrochemical synthesis of thienoacenes from S-methoxymethyl (MOM)-protected diarylacetylenes. In the presence of Bu4NBr as a halogen mediator, electrochemical double C?S cyclization of diarylacetylenes bearing two MOM groups proceeded to afford [1]benzothieno[3,2-b][1]benzothiophene (BTBT) derivatives. While S-Me or S-p-methoxybenzyl (PMB)-protected diarylacetylenes did not afford BTBT, BTBT was selectively obtained when a substrate protected with S-MOM groups was used. The S-MOM protection strategy is also effective for the electrochemical synthesis of a more π-expanded thienoacene such as dibenzo[d,d′]thieno[3,2-b,4,5-b′]dithiophene (DBTDT).

kn-title=Enhancing Protection Against Code Reuse Attacks on IoT Devices by Randomizing Function Addresses
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Most Internet of Things (IoT) devices currently in use are vulnerable to code reuse attacks because manufacturers typically deploy the same firmware across all devices. This uniformity enables attackers to craft a single exploit that can compromise multiple devices. To mitigate this risk, we propose a firmware diversification approach that creates multiple executable files with varying software compositions. Our approach introduces two complementary techniques: Function Address Reordering (FAR), which randomizes the order of functions within object files during compilation, and Object Address Reordering (OAR), which permutes the linking order of object files in the final executable. These techniques collectively diversify firmware instances without altering runtime behavior, making executing code reuse attacks significantly more difficult. By deploying firmware with diverse executable files, it is possible to enhance security without altering device behavior. We evaluate the effectiveness and limitations of the proposed methods when integrated into actual IoT firmware, assessing their resilience to code reuse attacks, impact on runtime behavior, and compilation overhead. Experimental results demonstrate that FAR and OAR significantly reduce the success rate of return-oriented programming attacks while incurring minimal performance overhead. This study offers a scalable, hardware-independent defense against code reuse attacks that increases resilience without a significant performance overhead, rendering it practical for widespread adoption in various IoT applications.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=To clarify the effects of the grain size and crystal orientation on the tensile properties of pure titanium thin wires, tensile and stepwise tensile tests were conducted on pure titanium wires with diameters of approximately 180 μm and different average grain sizes (52, 37, 23, and 3.8 μm). When the grain size was large, the fracture strain was significantly smaller, the variation in tensile strength was larger, and the grain size threshold for such properties was a grain-size ratio to wire diameter of 0.13 or greater. For larger grain sizes, the slip system with the highest modified Schmid factor (MSF), which is the Schmid factor divided by the critical resolved shear stress of each slip system, was activated in all 15 grains whereas for smaller grain sizes, the percentage of slip systems activated with the highest MSF was slightly lower. In addition, the fracture location in a thin wire with larger grain sizes was highly correlated with the average MSF of the grains in the cross-section.

kn-title=Effect of Repeated Gravity Casting on the Microstructure and Mechanical Properties of 6061 Aluminum Alloy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study systematically investigates the effects of repeated gravity casting on the microstructure and mechanical properties of 6061 aluminum alloy. With an increasing number of casting cycles from one to ten, grain coarsening and a decrease in dislocation density were observed, mainly due to the significant depletion of magnesium from 1.03 to 0.01% and titanium from 0.009 to 0.005%. These microstructural changes led to a decrease in solid-solution strengthening and grain-boundary strengthening, resulting in a 30% reduction in tensile strength, while ductility increased by about three times. Moreover, work hardening decreased with increasing the casting cycle, which can be attributed not only to the microstructural changes but also to the increase in stacking fault energy (SFE) associated with compositional evolution. From the transmission electron microscopy (TEM) observations, in the 1-cycle sample, Mg2Si precipitates were finely dispersed and a high amount of Mg element in the matrix, resulting in significant dislocation accumulation, whereas the 10-cycle sample exhibited weaker dislocation tangling. These microstructural evolutions provide insight into the degradation of mechanical performance in aluminum alloys subjected to multiple casting processes.

kn-title=Enhanced electric power generation in PZT ceramics via stress control
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study aimed to enhance the electric power generation of lead zirconate titanate piezoelectric (PZT) ceramics by optimizing stress distribution. Specifically, it focused on applying high stress over a broad area of the PZT ceramic to induce shape deformation in the PZT plate. Pre-straining the PZT plate into an arch shape improved voltage generation, reaching its peak at a maximum deflection of 0.04?mm due to the expanded and intensified stress distribution. However, exceeding this deflection threshold led to a decline in voltage output due to material degradation, including crack formation and 90° domain switching. Finite element analysis confirmed that the increased stress distribution in the pre-strained PZT plate contributed to higher voltage output. Additionally, electron backscatter diffraction analysis revealed that at higher pre-strains (deflection of 0.08?mm), 90°domain switching occurred, resulting in increased internal strain and potential crack formation. Experimental investigations using bulk PZT rods further demonstrated that moderate pre-straining effectively enhanced voltage output.

en-abstract=
kn-abstract=As there is a technical issue to remove iron elements during aluminum recycling process, an attempt was made to evaluate the effectiveness of magnetic and gravitational separation methods for removing iron from Al-Si-Cu alloy (ADC12). A rare-earth samarium?cobalt (SmCo) magnet was employed during the solidification process to attract Fe-rich eutectic structures. The microstructural analysis revealed that block-like Fe-Cr-Si-based phases formed preferentially near the magnet and at the bottom of the crucible, suggesting that magnetic and gravity attraction contributed to the localized segregation of these phases. However, other Fe-based phases, including Fe-Si-based ones, are not strongly affected by magnet. Additionally, prolonged heating in the solid?liquid coexistence (SLC) region at 577 °C for 10 h led to the settling of a largely grown Fe-Cr-Si-rich crystal at the bottom of the crucible due to gravity. Other structures, such as Si-rich eutectic phases, were not influenced by gravity, which may be caused by the low density of Si compared to Fe one. From this approach, combining magnetic attraction and gravitational settling is a promising method to promote the removal of iron impurities from aluminum alloys.

kn-title=Electric Power Generation of PZT Piezoelectric Ceramics Using Both Direct and Inverse Piezoelectric Effects
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The power generation characteristics of lead zirconate titanate (PZT) piezoelectric ceramics (E-PZT) were experimentally investigated using a specialized PZT system which utilizes both the direct and inverse piezoelectric effects inherent to PZT materials. Specifically, electric voltage was generated from the vibration of E-PZT through the inverse piezoelectric effect, induced by mechanical energy transferred from the vibration of a PZT piezoelectric ceramic plate, such as a buzzer (B-PZT). In this system, an insulating material was placed between the B-PZT and E-PZT plates to address the electrical conductivity of the PZT ceramic. Various insulating materials with different thicknesses and different hardness were prepared. Additionally, the PZT systems were mounted in several distinct configurations to evaluate their power generation performance: a fully fixed around the PZT plate and a free-hanging setup. The influence of insulation materials and mounting conditions on electrical output was analyzed at various loading conditions, e.g., loading value and frequency. The results demonstrated that the generated electric voltage decreased with increasing insulation thickness and hardness, suggesting that thinner and softer insulating materials enhance output voltage. Conversely, when the PZT system was securely fixed around the PZT plate with an appropriate fixture, a higher and more stable electric voltage was generated. The voltage generated also varied by the loading condition, which is related to the strain value of the E-PZT plate, demonstrating a linear relationship between the strain and the output voltage. Notably, the strain was significantly influenced by resonant frequencies, which played a crucial role in achieving higher voltage outputs. Based on these experimental results, two power generation systems have been proposed.

kn-title=N-terminal domains and site-specific glycosylation regulate the secretion of avian melanocortin inverse agonists, agouti signaling protein (ASIP) and agouti-related protein (AGRP)
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Agouti signaling protein (ASIP) and agouti-related protein (AGRP) are paralogous inverse agonists of melanocortin receptors with distinct physiological roles, but their structural and biochemical properties in birds remain poorly understood. Here, we characterized chicken ASIP and AGRP proteins. Analysis of available sequences revealed that a motif resembling the mammalian proprotein convertase 1/3 (PC1/3, also known as PCSK1) cleavage site is conserved across a broad range of avian orders, but Western blot analysis of transfected Chinese hamster ovary (CHO-K1) cells and chicken hypothalamus detected no cleavage, suggesting that avian AGRP may not be post-translationally processed at this site. Chicken ASIP mRNA contains an in-frame upstream ATG (uATG) and a putative N-linked glycosylation site at Asn-42, both conserved across multiple avian orders. Overexpression in CHO-K1 cells showed that ASIP translated from either ATG produces a mature protein of the same size that is N-glycosylated at Asn-42 and exhibits markedly lower secretion efficiency than AGRP. Domain-swapping experiments revealed that the N-terminal domain reduces secretion, whereas a naturally occurring ASIP-b variant with an additional N-glycan at Asn-47 shows enhanced secretion. Proteasome inhibition increased intracellular ASIP, and endoglycosidase H (Endo H) sensitivity indicated endoplasmic reticulum (ER) retention, suggesting that the N-terminal domain limits secretion via ER-associated proteasomal degradation. These findings reveal species-specific post-translational regulation of avian melanocortin inverse agonists, in which N-terminal features and site-specific N-glycosylation determine secretion efficiency, likely contributing to their distinct roles in pigmentation and hypothalamic energy balance.

kn-title=Algebraic Connectivity Maximizing Regular Graphs: Special Case Analysis and Depth‐First Search
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The algebraic connectivity is an indicator of how well connected a graph is. It also characterizes the convergence speed of some dynamic processes over networks. In this paper, taking into account that homogeneous networks are modeled as regular graphs, we tackle the following problem: given a pair (?, ?) of positive integers such that ? is less than ? and kn is an even number, find a ?-regular graph with ? vertices that have the maximum algebraic connectivity. We first consider some special cases and derive solutions through theoretical analysis. We next present depth-first search algorithms for solving the problem, which reduce the search space by making use of some known properties of the regular graph and the algebraic connectivity.We also show the results of execution of the proposed algorithms for the values of ? up to 12.

kn-title=Coupling effects of biochar and sediment microbial fuel cells on CH4 and CO2 emissions from straw-amended paddy soil
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose The independent incorporation of biochar and sediment microbial fuel cells (SMFCs) into paddy soil has been shown to reduce methane (CH4) emissions. However, the application of rice straw into paddy soil enhances the availability of labile carbon that stimulates methanogen growth, counteracting the mitigation effects of both methods. This study, therefore, aimed to investigate the effect of coupling biochar and SMFC on CH4 and CO2 emissions from straw-amended paddy soil.<br>
Materials and methods Single chamber SMFC setups constructed using acrylic columns (height, 25 cm; inner diameter, 9 cm) with six treatments were established using soil amended with 0% (0BC), 1% (1BC), and 2% (2BC) biochar: with and without SMFC conditions. Stainless steel mesh (15?×?3 cm) and graphite felt (6?×?5 cm) were used as anode and cathode materials, respectively.<br>
Results Cumulative emission of CH4 in the 0BC treatment with SMFC was 39% less than in that without SMFC. Biochar addition and SMFC operation together further reduced CH4 emission by 57% and 60% in 1BC and 2BC treatments, respectively, compared to that in the 0BC treatment without SMFC operation. The relative abundance of microbial communities indicated methane-oxidizing bacteria were enriched in the presence of biochar and hydrogenotrophic Methanoregula were suppressed by SMFC operation. This suggested that SMFC mainly inhibited CH4 production by outcompeting hydrogenotrophic archaea.<br>
Conclusion The use of biochar made from leftover rice straw has an interactive effect on SMFC operation and both methods can be used to reduce CH4 emission from straw-amended paddy soil.

en-abstract=
kn-abstract=By examining the geometric characteristics of various boundaries formed within the Kagome phononic lattice and vertically stacking the lattices, we designed an elastic waveguide that enables selective propagation of topologically protected edge modes across layers in a bilayer system. This layer-selective transmission is manifested as polarized boundary modes that appear in phononic dispersions of the systems incorporating the bridge, zigzag, and armchair boundaries. We numerically demonstrated that efficient elastic layer converters and splitters can be designed, thereby paving the way for the practical development of three-dimensional elastic-wave devices.

kn-title=The effect of pressure on dihedral angle between liquid Fe‐S and orthopyroxene: Implication for percolative core formation in planetesimals and planetary embryos
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=During precursor stages of planet formation, many planetesimals and planetary embryos are considered to have differentiated, forming an iron-alloy core and silicate mantle. Percolation of liquid iron-alloy in solid silicates is one of the major possible differentiation processes in these small bodies. Based on the dihedral angles between Fe-S melts and olivine, a criterion for determining whether melt can percolate through a solid, it has been reported that Fe-S melt can percolate through olivine matrices below 3?GPa in an oxidized environment. However, the dihedral angle between Fe-S melts and orthopyroxene (opx), the second most abundant mineral in the mantles of small bodies, has not yet been determined. In this study, high-pressure and high-temperature experiments were conducted under the conditions of planetesimal and planetary embryo interiors, 0.5?5.0?GPa, to determine the effect of pressure on the dihedral angle between Fe-S melts and opx. Dihedral angles tend to increase with pressure, although the pressure dependence is markedly reduced above 4?GPa. The dihedral angle is below the percolation threshold of 60° at pressures below 1.0?1.5?GPa, indicating that percolative core formation is possible in opx-rich interiors of bodies where internal pressures are lower than 1.0?1.5?GPa. The oxygen content of Fe-S melt decreases with increasing pressure. High oxygen contents in Fe-S melt reduce interfacial tension between Fe-S melt and opx, resulting in reduced dihedral angles at low pressure. Combined with previous results for dihedral angle variation of the olivine/Fe-S system, percolative core formation possibly occurs throughout bodies up to a radius of 1340?km for an olivine-dominated mantle, and up to 770?km for an opx-dominated mantle, in the case of S-rich cores segregating under relatively oxidizing conditions. For mantles of small bodies in which abundant olivine and opx coexist, the mineral with the largest volume fraction and/or smallest grain size will allow formation of interconnected mineral channels, and, therefore, the wetting property of this mineral determines the wettability of the melt, that is, controls core formation.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Not all file in firmware are executed while using Internet of Things (IoT) devices and hundreds to approximately a thousand executable and linkable format files exist in one firmware. Therefore, security investigations without prioritization may lead to investigate programs that are not executed while using IoT devices first. This has resulted in inefficient security investigations. To perform efficient security investigations, we proposed a method that can identify programs executed during the startup process. However, only two firmware were used for the evaluation which can only evaluate one of the two startup sequences in the OpenWrt-based firmware. In addition, security investigations to validate whether the proposed method addresses the problem of inefficient security investigations were limited to OpenWrt-based firmware. In this study, we use more firmware data for evaluation and validation. We use nine firmware not used in previous studies including startup methods that have not previously been used for evaluation. In addition, we increase the number of firmware used for validation to 225. The evaluation results demonstrate that the proposed method can identify with only few false positives. The validation demonstrates that efficiency can be improved and prioritizing investigations by considering the proposed method result is worthwhile.

kn-abstract=The Ti-18mass%Nb alloy with a quenched α” martensitic structure exhibited a high damping capacity. However, there are issues such as lower strength than annealed α+β structure and decreasing damping capacity due to heating until 400 K. Therefore, in this study, to address these issues, we investigated the effect of Al addition on the constituent phases and material properties of Ti-18Nb-xAl alloys. The crystal structure was determined by examining the lattice constant and unit volume using X-ray diffraction, and optical microscopy was also performed. The material properties were investigated by Vickers hardness, Young’s modulus, internal friction, tensile tests, and DSC measurements. Vickers hardness and tensile strength increased with increasing Al content. This is thought to be due to the combined effects of the refinement of the microstructure and solid-solution strengthening due to Al addition. The Young’s modulus increased slightly from 0Al to 1Al, but increased significantly to 4Al. Internal friction was highest for 0Al and decreased for 4Al, whereas 7Al showed a higher value than 1Al. In the DSC heating curves, there was a decrease in the exothermic peak starting temperature and an increase in the phase-transformation heat with the addition of Al, except for 1Al. It was suggested that these changes in Ti-18Nb-xAl alloys were influenced by the structure of the quenched α” phase, texture, and pseudoelasticity or phase transformation by deformation.

kn-title=Creep damage parameters based on the distribution of cavities on grain boundaries
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=When polycrystalline heat-resistant steels are subjected to static or cyclic loading at high temperatures, they can exhibit various fracture modes and processes. This paper begins by outlining representative methods for life assessment under creep-dominated conditions. It then discusses the fracture processes and the underlying mechanisms. Under creep-dominated conditions, the initiation and growth of cavities serve as the primary form of material damage, making their quantitative assessment essential. Several parameters have been proposed to evaluate cavity distributions quantitatively. However, the relationship between these parameters and the actual cavity distribution in materials, as well as their physical significance, has remained unclear. In this study, a simple cavity distribution model was employed to clarify these issues. The results suggest that the area fraction of cavities is an appropriate damage evaluation parameter for transgranular fracture, while the fraction of cavities on grain boundary line is suitable for intergranular fracture.

kn-title=Surrogate-assisted motion planning and layout design of robotic cellular manufacturing systems
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A surrogate-assisted multi-objective evolutionary algorithm is proposed for simultaneous optimization of robot motion planning and layout design in robotic cellular manufacturing systems. A sequence-pair is used to represent the layout of components in a robotic cell to avoid overlapping in the evolutionary computation. The robot motion planning with Rapidly exploring Random Trees Star (RRT*) is applied to compute the total operation time of a robot arm for each layout. Non-dominated Sorting Genetic Algorithm II (NSGA-II) is used to minimize the total required layout area and the operation time for a robot arm. The proposed surrogate model can estimate the robot’s operation time with 98% of accuracy without explicit computations of the motion planning algorithm. The experimental results with a physical 6 Degree of Freedom (DOF) manipulator show that the total computation time is approximately 1/400, significantly shorter than the conventional methods.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The use of nutrient-rich feed in shrimp farming in Central Vietnam has led to high nitrogen (N) and phosphorus (P) contents in the pond sediment. The objectives of the study were to assess the effectiveness of biochar-sediment microbial fuel cells (BC-SMFCs) in suppressing P and N release from two types of sediment in intensive (Int) and extensive (Ext) pond drainages in Central Vietnam. Single chamber SMFCs were set up and operated under open or closed-circuit (no SMFC or SMFC) conditions. Coconut shell biochar (BC) was amended to sediments at 1%. For Int-sediment, total phosphorus (TP) release was reduced by no BC-SMFCs through co-precipitation with Fe. On the other hand, BC-SMFCs did not suppress TP release because P was released from BC and organic matter decomposition was enhanced in the sediment. Application of BC enhanced organic N mineralization in the sediment. Nitrification and denitrification occurred in the overlying water, reducing mineral N concentrations. For Ext-sediment, BC addition and SMFC conditions did not affect TP and total nitrogen (TN) release because of low initial organic matter content, and less reductive condition. Our study suggested that the effect of SMFCs was masked by BC which released more P from Int-sediment to the water.

kn-title=Evaluating the effects of electrolytes on the interaction forces between alumina surfaces in polyacrylic acid solutions using atomic force microscopy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Evaluation and control of ceramic slurry at the microscopic level are critical to ensure consistent quality in manufactured ceramics. Notably, metal ions such as Mg2+ and Al3+ are common in ceramic slurries and significantly influence the stability of particle. This study applied atomic force microscopy to investigate the interaction forces between alumina particle surfaces in the presence of different concentrations of three metal ions and polyacrylic acid (PAA), a widely used dispersant.<br>
The attractive forces observed at low PAA concentrations were attributed to polymer bridging between alumina surfaces, whereas the repulsive forces observed at high PAA concentrations were attributed to the domination of steric repulsion between adsorbed PAA molecules. The presence of multivalent metal ions, such as Mg2+ and Al3+, modulated these interactions; an increasing ion valence induced a transition from repulsive to attractive force, primarily owing to electrostatic screening, which caused conformational collapse of the PAA chains and diminished the range of steric repulsion. Similarly, increasing the concentration of these metal ions decreased the range of repulsive forces, eventually resulting in a net attraction driven by the same electrostatic and polymer conformation mechanisms. Notably, the addition of 0.1 M AlCl3 produced an anomalous long-range attraction between surfaces that could not be explained by conventional mechanisms, such as polymer bridging or electrostatic interactions between charge domains.

kn-title=The response to thermospermine is fine-tuned by the balance between SAC51 and LHW family proteins in Arabidopsis thaliana
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Thermospermine negatively regulates xylem formation. In Arabidopsis, SAC51 and SACL3, members of the SAC51 gene family encoding basic loop-helix-loop (bHLH) proteins play a key role in this regulation. These mRNAs contain an upstream open-reading-frame (uORF) that is highly conserved across species, and its inhibitory effect on the main ORF translation is alleviated by thermospermine. A double knockout of SAC51 and SACL3 results in thermospermine insensitivity at high concentrations that normally inhibit xylem formation and shoot growth in the wild type. Conversely, uORF mutants of SAC51, SACL3, and SACL1 suppress the excessive xylem formation and dwarf phenotype of acl5, a mutant defective in thermospermine biosynthesis. In this study, we generated genome-edited uORF mutants of SACL2 and confirmed that they partially recover the acl5 phenotype. All uORF mutants exhibited increased sensitivity to thermospermine. SACL3 represses the function of LHW, a key bHLH transcription factor required for xylem proliferation, through direct interaction. We found that the lhw mutant is also hypersensitive to thermospermine, while this sensitivity was suppressed by the sac51 sacl3 double knockout. Yeast two-hybrid assays demonstrated that all four SAC51 family members interact with LHW and its family members. These findings suggest that overaccumulation of SAC51 family proteins leads to thermospermine hypersensitivity by repressing the function of LHW family proteins, whose activity must be fine-tuned to ensure proper xylem development.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Thermospermine is involved in negative regulation of xylem differentiation by enhancing the translation of mRNAs of the SAC51 gene family in Arabidopsis (Arabidopsis thaliana). These mRNAs contain conserved upstream open reading frames (uORFs) that interfere with the translation of the main ORF. To investigate the mechanism by which thermospermine acts in this process, we isolated mutants insensitive to thermospermine, named ‘its’. We show that the four genes responsible for these mutants, its1 to its4, encode: (i) a homolog of SPOUT RNA methyltransferase, (ii) an rRNA pseudouridine synthase CBF5/NAP57, (iii) a putative spliceosome disassembly factor STIPL1/NTR1, and (iv) a plant-specific RNA-binding protein PHIP1. These four mutants were found to have much higher levels of thermospermine than the wild-type. While all these mutants except its1 appear almost normal, they enhance the dwarf phenotype of a mutant of ACL5, which encodes thermospermine synthase, resulting in tiny plants resembling a double knockout of ACL5 and SACL3, a member of the SAC51 family. Reporter assays revealed that GUS activity from the CaMV 35S promoter-SAC51 5′-GUS fusion construct was significantly reduced in its1 and its4 or not affected in its2 and its3, while it was slightly increased in its1, its3, and its4, or not changed in its2 by thermospermine. These findings underscore the critical role of RNA processing and modification in the thermospermine-dependent translational regulation of uORF-containing transcripts.

kn-title=Effect of environmental conditions on seed germination and seedling growth in Cuscuta campestris
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Dodder (Cuscuta) is an obligate parasitic plant that cannot survive without a host and causes significant damage to crop yields. To understand its growth characteristics before parasitism, we examined the effects of environmental conditions on seed germination and seedling growth in Cuscuta campestris Yunck. Among various factors, we focused on the effects of light, pH, temperature, sugars, salts, hormones, amino acids and polyamines on seeds sown on agar plates. Regarding the effect of light on germination, far-red light was preferable rather than red light and the reversible response of seeds to red and far-red light was confirmed, implicating a phytochrome-mediated signaling pathway opposite to that in many seed plants. Among the amino acids, aspartic acid and alanine had a promotive effect, while histidine had an inhibitory effect on germination. We further found that, in addition to gibberellic acid, methyl jasmonate stimulated both germination and shoot elongation. While 2,4-D extended the viability of trichomes around the root cap, kinetin induced the formation of scale leaves on the shoot and undifferentiated cell clusters at the base of the shoot and root tip. Real-time reverse transcriptase PCR (RT-PCR) experiments confirmed that the expression of a putative RbcS gene for photosynthesis showed no response to light, whereas that of a Phytochrome A homolog increased in the dark. Our results indicate that some of the molecular mechanisms involved in responding to light and hormone signals are uniquely modified in dodder seedlings, providing clues for understanding the survival strategy of parasitic plants.

kn-title=Optical bandgap tuning in SnO2?MoS2 nanocomposites: manipulating the mass of SnO2 and MoS2 using sonochemical solution mixing
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study investigates controlled optical bandgap tuning through precise adjustment of the SnO2 and MoS2 mass in nanocomposites. A sonochemical solution mixing method, coupled with bath sonication, is employed for the preparation of SnO2?MoS2 nanocomposite. This approach allows for comprehensive characterization using UV?Vis FTIR, XRD, EDX, Raman spectroscopies, and FESEM, providing insights into morphology, chemical, and optical properties. Increasing the SnO2 mass leads to a linear decrease in the optical bandgap energy, from 3.0 to 1.7 eV. Similarly, increasing the MoS2 mass also results in a decrease in the optical bandgap energy, with a limitation of around 2.01 eV. This work demonstrates superior control over optical bandgap by manipulating the SnO2 mass compared to MoS2, highlighting the complexities introduced by MoS2 2D nanosheets during sonication. These findings hold significant value for optoelectronic applications, emphasizing enhanced control of optical bandgap through systematic mass manipulation.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The study investigated the constraints associated with the dilution technique in determining the optical bandgap of nanoparticle dispersion and modified nanocomposites, utilizing ultraviolet-visible absorbance spectra and Tauc plot analysis. A case study involving SnO2 dispersion and SnO2-MoS2 nanocomposite solutions, prepared through the direct solution mixing method, was conducted to assess the implications of dilution upon the absorbance spectra and bandgap estimation. The results emphasize the considerable impact of the dilution technique on the measured optical bandgap, demonstrating that higher dilution factors lead to shift in bandgap values. Furthermore, the study highlights that dilution can induce variations in the average nanoparticle sizes due to agglomeration, thereby influencing bandgap estimation. In the context of nanocomposites, the interaction between SnO2 nanoparticles and exfoliated MoS2 nanosheets diminishes with increasing dilution, leading to the estimated optical bandgap being primarily attributable to SnO2 nanoparticles alone. These observations underscore the necessity for caution when employing the dilution technique for bandgap estimation in nanoparticles dispersion and nanocomposites, offering valuable insights for researchers and practitioners in the field.

kn-title=Study on an Effective Coolant Supply Method in the Side Plunge Grinding Process
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Grinding is widely used for finishing components with journal and thrust surfaces, such as crankshafts. Side-plunge grinding enables the simultaneous finishing of thrust and cylindrical surfaces in a single plunge. However, compared to cylindrical grinding, it involves a larger contact area between the grinding wheel and the workpiece, leading to increased heat generation. In particular, poor coolant penetration near internal corners can degrade surface quality, potentially causing stress concentrations and cracks. To enhance coolant effectiveness in side-plunge grinding, this study installs a high-pressure nozzle that supplies coolant from the side of the grinding wheel. The effectiveness of this setup is experimentally verified. Additionally, the distribution of coolant flow within the contact area between the grinding wheel and the workpiece is measured to determine the optimal nozzle position for efficient coolant delivery. The nozzle’s performance is evaluated by measuring the workpiece surface temperature using a wire/workpiece thermocouple, the amount of coolant discharged from the grinding wheel, and the residual stress distribution. The results show that coolant penetrates the grinding wheel and effectively reaches the grinding zone, enhancing the cooling effect. This study clarifies the relationship between effective coolant supply and the position of the side nozzle. Considering physical constraints, such as potential interference during grinding, the optimal nozzle location is as close as possible to both the edge of the grinding wheel and the workpiece. This positioning ensures maximum coolant delivery, reduces grinding temperature, and helps suppress drastic variations in residual stress.

kn-title=Thermally polymerizable phthalocyanine realizes a metal?nitrogen-doped carbon material featuring a defined single-atom catalyst motif with CO2RR activity
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Metal?nitrogen-doped carbon materials (MNCs) exhibit good electrocatalytic performance owing to the intrinsic advantages of carbon-based materials and the presence of isolated and stabilized metal atoms coordinated by nitrogen sites. However, conventional high-temperature pyrolysis of precursor molecules make it difficult to control the coordination structure precisely. To address this issue, here we report a new synthesis strategy for MNCs. Specifically, we design and synthesize Ni-phthalocyanine functionalized with ethynyl groups as solid-state thermal polymerization points. After depositing the Ni-phthalocyanine precursor on a carbon support and performing a thermal treatment, the resultant carbon composite material features a Ni?N4 coordination structure derived from the precursor, and enhanced porosity. This material demonstrates high catalytic activity for the CO2 reduction reaction (CO2RR). Our synthetic approach is applicable to various precursor molecules and carbon supports, paving the way for the further development of MNC-based electrode catalysts.

kn-title=Organic solvent transport through reduced graphene oxide membranes with controlled oxygen content
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Recent advances in membranes based on 2-dimensional (2D) materials have enabled precise control over angstrom-scale pores, providing a unique platform for studying diverse mass transport mechanisms. In this work, we systematically investigate the transport of solvent vapors through 2D channels made of graphene oxide (GO) laminates with precisely controlled oxygen content. Using in-situ chemical reduction of GO with vitamin C, we fabricated reduced GO membranes (VRGMs) with oxygen content systematically decreased from 31.6 % (pristine GO) to 24.0 % (VRGM-maximum reduction). Vapor permeability measurements showed a distinct correlation between oxygen functional groups and solvent transport behaviour. Specifically, non-polar hexane exhibits 114 % of enhanced permeance through the reduced membranes with larger graphitic domains, while the permeance of water decreases by 55 %. With the support of density functional theory (DFT) simulations, we modelled the hydrogen-bond and dispersion complexes between the solvents and GO and calculated the complexation energies. The simulation results suggest that polar molecules interact with the oxygen functional groups of GO via a hydrogen-bond network, supporting in-plane transport. In contrast, van der Waals forces drive the transport of low-polarity solvents along the graphitic domains of the 2D channel in reduced GO membranes. Our findings provide potential strategies for future design of organic solvent nanofiltration membranes.

kn-title=Covalent cross-linked graphene oxide aerogels for moisture adsorption
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Covalent cross-linking is an effective approach to enhance the hydrophilicity and water adsorption properties of graphene oxide (GO). We studied moisture absorption in GO cross-linked with poly(ethylene glycol) diamines. At relative humidity (RH) of 85%, the PEG-cross-linked GO exhibited a significantly enhanced water uptake capacity of 0.59 g of water per gram of GO (gg?1), compared to 0.37 for unmodified GO. This is attributed to the presence of alkoxy groups via cross-linking, resulting in the enhanced interaction between GO and water molecules. These findings highlight the potential of PEG-based covalent functionalisation for efficient moisture capture in GO-based materials.

kn-title=RNA Delivery Using a Graphene Oxide-Polyethylenimine Hybrid Inhibiting Myotube Differentiation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Graphene oxide (GO) conjugated with short polyethylenimine (PEI) chains (GO-PEI) has been designed as a candidate nanocarrier for small interfering RNA (siRNA) delivery to mammalian cells based on the efficient interaction between the positively charged GO-based platform and the negatively charged siRNA. The function and efficiency of siRNA delivery using GO-PEI were compared to those using the positive control Lipofectamine RNAiMax by analyzing the differentiation to myotubes, and myogenin gene and protein expression in C2C12 cells. RNAiMax transfection induced cellularization and reduction of both myogenin gene and protein expression, suggesting that the differentiation of C2C12 cells was triggered by gene silencing. While GO-PEI also promoted cellularization, the myogenin gene expression remained comparable to scrambled controls, whereas the protein levels were higher than those observed with RNAiMax. Mechanistically, we attributed the reduced gene silencing efficiency of GO-PEI to a poor endosomal escape, despite strong siRNA complexation. This limitation was likely due to a low buffering capacity of GO-PEI, as a significant fraction of nitrogen atoms were already protonated, reducing the availability of free amines necessary for endosomal disruption. An appropriate chemical modification to enhance siRNA release from the endosomes is therefore essential for advancing the development of GO-based platforms as versatile and efficient nanocarriers in gene therapy applications.

kn-title=Integration of Cholesterol Oxidase‐Based Biosensors on a Smart Contact Lens for Wireless Cholesterol Monitoring from Tears
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease. Regular cholesterol monitoring is essential for elderly or obese individuals. Current methods, such as blood tests, are invasive, inconvenient, and require a professional operator. In contrast, tears, as an accessible body fluid, offer a promising alternative for noninvasive monitoring due to their correlation with blood cholesterol levels. Herein, a noninvasive approach for monitoring cholesterol levels in tears using a biosensor integrated into a smart contact lens is reported. The biosensor employs cholesterol oxidases as the biocatalyst, coupled with an osmium-based mediator, to detect cholesterol concentrations ranging from 0.1?mM to 1.2?mM in artificial tears. A key challenge is the extremely low cholesterol concentration in tears, which is addressed using a parity-time (P-T) symmetry-based magnetic resonance coupling system. This system enables wireless signal reading and achieves high sensitivity due to its high-quality (Q) factor, which can achieve a detection limit of 0.061?mM. This portable, high-sensitivity smart contact lens demonstrates significant potential as a wearable device for continuous, noninvasive cholesterol monitoring. The findings contribute to advancing tear-based diagnostic systems and highlight the scientific importance of utilizing tear biomarkers for health monitoring.

kn-title=Optimized Ensemble Deep Learning for Real-Time Intrusion Detection on Resource-Constrained Raspberry Pi Devices
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The rapid growth of Internet of Things (IoT) networks has increased security risks, making it essential to have effective Intrusion Detection Systems (IDS) for real-time threat detection. Deep learning techniques offer promising solutions for such detection due to their superior complex pattern recognition and anomaly detection capabilities in large datasets. This paper proposes an optimized ensemble-based IDS designed specifically for efficient deployment on edge hardware. However, deploying such computationally intensive models on resource-limited edge devices remains a significant challenge due to model size and computational overhead on devices with limited processing capabilities. Building upon our previously developed stacked Long Short-Term Memory (LSTM) model integrated with ANOVA feature selection, we optimize it by integrating dual-stage model compression: pruning and quantization to create a lightweight model suitable for real-time inference on Raspberry Pi devices. To evaluate the system under realistic conditions, we combined with a Kafka-based testbed to simulate dynamic IoT environments with variable traffic loads, delays, and multiple simultaneous attack sources. This enables the assessment of detection performance under varying traffic volumes, latency, and overlapping attack scenarios. The proposed system maintains high detection performance with accuracy of 97.3% across all test scenarios, while efficiently leveraging multi-core processing with peak CPU usage reaching 111.8%. These results demonstrate the system’s practical viability for real-time IoT security at the edge.

kn-title=Security in Post-Quantum Era: A Comprehensive Survey on Lattice-Based Algorithms
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Lattice-based post-quantum cryptography (PQC) has attracted significant attention as a promising solution to the security challenges posed by quantum computing. Unlike traditional cryptographic algorithms, lattice-based schemes are expected to remain secure even in the presence of quantum attacks, making them essential for securing future data. Despite their strong theoretical foundations, lattice-based schemes face several practical challenges, particularly in optimizing performance and scalability for real-world applications. This survey provides a novel taxonomy that categorizes lattice-based PQC designs, with an emphasis on computational paradigms and security considerations. We systematically evaluate lattice-based PQC implementations across both software platforms, including central processing units and graphics processing units, as well as hardware platforms like field-programmable gate arrays and application-specific integrated circuits, highlighting their strengths and limitations. In addition, we explore the practical applications of lattice-based cryptography in fields such as secure communication, critical infrastructure, privacy-preserving data analytics, artificial intelligence, and trust and authentication systems. By offering a comprehensive overview of the current state of lattice-based PQC, this survey aims to provide valuable insights into the ongoing advancements and future research directions in the field as we transition to a post-quantum era.

kn-title=MATERIAL PROPERTIES OF DIE-CASTING DIE AROUND HEAT-CHECKING CREATED BY A HIGH-PRESSURE ALUMINUM ALLOY DIE-CASTING OPERATION
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this study, the material properties of a nitride die-casting die exhibiting heat-checking after the die-casting process were experimentally investigated using various methods. Based on the obtained results, the authors believe that several possible mechanisms underlying the formation of heat-checking can be identified. The microstructure of the die-casting die near the heat-checking region is characterized by equiaxed grains along the vicinity of the prior γ-grain boundaries, resulting from the lath martensitic formation. Additionally, numerous Cr?Mo?V-based nitride particles, approximately 100 nm in diameter, are precipitated. The surface hardness of the die-casting die, enhanced by nitriding, induces compressive residual stresses and increases adhesive forces. As a result of changes in microstructural characteristics and crack formation, the stress state near the die-casting die is altered, where compressive residual stresses, observed in the die-casting die, are released, leading to the tensile residual stresses. This phenomenon could accelerate the formation of a large number of heat-checking cracks.

kn-title=An Implementation of Creep Test Assisting System with Dial Gauge Needle Reading and Smart Lighting Function for Laboratory Automation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=For decades, analog dial gauges have been essential for measuring and monitoring data at various industrial instruments including production machines and laboratory equipment. Among them, we focus on the instrument for creep test in a mechanical engineering laboratory, which evaluates material strength under sustained stress. Manual reading of gauges imposes significant labor demands, especially in long-duration tests. This burden further increases under low-lighting environments, where poor visibility can lead to misreading data points, potentially compromising the accuracy of test results. In this paper, to address the challenges, we implement a creep test assisting system that possesses the following features: (1) to save the installation cost, a web camera and Raspberry Pi are employed to capture images of the dial gauge and automate the needle reading by image processing in real time, (2) to ensure reliability under low-lighting environments, a smart lighting mechanism is integrated to turn on a supplementary light when the dial gauge is not clearly visible, and (3) to allow a user to stay in a distant place from the instrument during a creep test, material break is detected and the corresponding message is notified to a laboratory staff using LINE automatically. For evaluations, we install the implemented system into a material strength measuring instrument at Okayama University, Japan, and confirm the effectiveness and accuracy through conducting experiments under various lighting conditions.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Functional CO2-based polycarbonates are expected to be sustainable materials. Herein, a bifunctional aluminum porphyrin catalyzed the terpolymerization of cyclohexene oxide (CHO), acrylate-appended CHO, and CO2 to provide poly(cyclohexene carbonate)s (PCHCs) with acrylate groups. Postfunctionalization of PCHCs via Michael addition or Heck reaction enabled the incorporation of thiol, amine, and aromatics into PCHCs with high selectivity and efficiency. PCHCs with the flexible long alkyl chains showed a glass-transition temperature (Tg) of down to 52 °C, which was much lower than that of PCHC (127 °C). In sharp contrast, PCHCs with rigid pyrenyl groups showed Tg values of up to 152 °C and fluorescence emission. Thus, a wide range of polymers were obtained by robust and sustainable synthetic methods, and the functional groups modulated the properties of the CO2-based polycarbonates.

kn-title=Optical and chemical properties of silver tree-like structure treated with gold galvanic substitution
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Galvanic gold substitution was executed in the presence of trisodium citrate on silver tree-like structures. No discernible difference in geometry was observed between the pre- and post-gold substitution phases, which benefited from the presence of citrate ions. The extent of gold substitution was regulated by the amount of gold ion solution added. After the gold substitution, an increase in extinction was observed in the ultraviolet region, indicating that gold was deposited at the surface. Raman scattering of para-toluenethiol was measured on the gold/silver tree-like structures at 488 nm excitations, where a decrease in the Raman peak intensity was observed as the quantity of gold ion solution increased. The results indicated that the optical property of silver was lost due to the increase of the amount of gold deposition. Concurrently, an investigation was conducted into the chemical resistance of the gold/silver tree-like structures, which was evaluated by measuring the resistivity inverse-proportional to the amount of silver ions dissolved by the diluted nitric acid. As the amount of gold ion solution added increased, the resistivity increased and became constant. The result implied that the surface chemical property had undergone a complete transformation into gold.

kn-title=A plant-insertable multi-enzyme biosensor for the real-time monitoring of stomatal sucrose uptake
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Monitoring sucrose transport in plants is essential for understanding plant physiology and improving agricultural practices, yet effective sensors for continuous and real-time in-vivo monitoring are lacking. In this study, we developed a plant-insertable sucrose sensor capable of real-time sucrose concentration monitoring and demonstrated its application as a useful tool for plant research by monitoring the sugar-translocating path from leaves to the lower portion of plants through the stem in living plants. The biosensor consists of a bilirubin oxidase-based biocathode and a needle-type bioanode integrating glucose oxidase, invertase, and mutarotase, with the two electrodes separated by an agarose gel for ionic connection. The sensor exhibits a sensitivity of 6.22 μA mM?1 cm?2, a limit of detection of 100 μM, a detection range up to 60 mM, and a response time of 90 s at 100 μM sucrose. Additionally, the sensor retained 86 % of its initial signal after 72 h of continuous measurement. Day-night monitoring from the biosensor inserted in strawberry guava (Psidium cattleianum) showed higher sucrose transport activity at night, following well the redistribution of photosynthetically produced sugars. In addition, by monitoring the forced translocation of sucrose dissolved in the stable isotopically labeled water, we demonstrated that a young seedling of Japanese cedar known as Sugi (Cryptomeria japonica) can absorb and transport both water and sucrose through light-dependently opened stomata, which is the recently revealed path for liquid uptake by higher plants. These findings highlight the potential of our sensor for studying dynamic plant processes and its applicability in real-time monitoring of sugar transport under diverse environmental conditions.

kn-title=Crystal Grain Rotation during Tensile Test of Polycrystalline Pure Titanium Thin Sheet Based on Surface Height and Crystal Orientation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Thin sheets and wires of polycrystalline pure titanium are important materials for various devices used in electrical, mechanical, dental, and medical fields. Since pure titanium shows strong anisotropy in elastic and plastic deformation, and the individual grains comprising a polycrystalline body have different orientations and geometries, inhomogeneous deformation always occurs on the microscopic scale. This inhomogeneity is more significant in thin films than in bulk materials. It is therefore important to investigate the inhomogeneous deformation of pure titanium thin sheets to ensure the reliability of various titanium devices. In this study, thin-sheet specimens made of polycrystalline pure titanium were subjected to tensile testing. Inhomogeneous deformation was evaluated on the basis of two kinds of crystal grain rotations based on surface height and crystal orientation. The results under elastic and plastic tensile conditions were compared.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The redox potential is an important factor for controlling the outcome of photoredox catalysis. Particularly, the selective oxidation of substrates and the control over the reactions are challenging when using photoredox catalysts that have high excited-state reduction potentials. In this study, a redox-potential-controlled intermolecular [2 + 2] cycloaddition of styrenes using a thioxanthylium organophotoredox (TXT) catalyst has been developed. This TXT catalyst selectively oxidizes β-halogenostyrenes and smoothly promotes the subsequent intermolecular [2 + 2] cycloadditions to give multisubstituted halogenocyclobutanes with excellent regio- and diastereoselectivity, which has not been effectively achieved by the hitherto reported representative photoredox catalysts. The synthesized halogenocyclobutanes exhibit interesting free radical scavenging activity. The present reaction contributes to the field of redox-potential-controlled electron transfer chemistry.

kn-title=Elucidation of the relationship between solid‐state photoluminescence and crystal structures in 2,6‐substituted naphthalene derivatives
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Polycyclic aromatic hydrocarbons (PAHs) are known to exhibit fluorescence in solution, but generally do not emit in the solid state, with the notable exception of anthracene. We previously reported that PAHs containing multiple chromophores show solid-state emission, and we have investigated the relationship between their crystal structures and photoluminescence properties. In particular, PAHs with herringbone-type crystal packing, such as 2,6-diphenylnaphthalene (DPhNp), which has a slender and elongated molecular structure, exhibits red-shifted solid-state fluorescence spectra relative to their solution-phase counterparts. In this study, we synthesized 2,6-naphthalene derivatives bearing phenyl and/or pyridyl substituents (PhPyNp and DPyNp) and observed distinct, red-shifted emission in the solid state compared with that in solution. Crystallographic analysis revealed that both PhPyNp and DPyNp adopt herringbone packing motifs. These findings support our hypothesis that the spectral characteristics of PAH emission are closely linked to crystal packing arrangements, providing a useful strategy for screening PAH candidates for applications in organic semiconducting materials.

kn-title=Polyglycerol‐Grafted Graphene Oxide with pH‐Responsive Charge‐Convertible Surface to Dynamically Control the Nanobiointeractions for Enhanced in Vivo Tumor Internalization
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=pH-responsive charge-convertible nanomaterials (NMs) ameliorate the treatment of cancer via simultaneously reducing nonspecific interactions during systemic circulation and improving targeted uptake within solid tumors. While promising, little is known about how the pH-responsiveness of charge-convertible NMs directs their interactions with biological systems, leading to compromised performance, including off-target retention and low specificity to tumor cells. In the present study, polyglycerol-grafted graphene oxide bearing amino groups (GOPGNH2) at different densities are reacted with dimethylmaleic anhydride (DMMA), a pH-responsive moiety, to generate a set of charge-convertible GOPGNH-DMMA variants. This permits the assessment of a quantitative correlation between the structure of GOPGNH-DMMA to their pH-responsiveness, their dynamic interactions with proteins and cells, as well as their in vivo biological fate. Through a systematic investigation, it is revealed that GOPGNH115-DMMA prepared from GOPGNH2 with higher amine density experienced fast charge conversion at pH 7.4 to induce non-specific interactions at early stages, whereas GOPGNH60-DMMA and GOPGNH30-DMMA prepared from lower amine density retarded off-target charge conversion to enhance tumor accumulation. Notably, GOPGNH60-DMMA is also associated with enough amounts of proteins under acidic conditions to promote in vivo tumor internalization. The findings will inform the design of pH-responsive NMs for enhanced treatment accuracy and efficacy.

kn-title=N-Phenylphenothiazine Radical Cation with Extended π-Systems: Enhanced Heat Resistance of Triarylamine Radical Cations as Near-Infrared Absorbing Dyes
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=N-Phenylphenothiazine derivatives extended with various aryl groups were designed and synthesized. These derivatives have bent conformation in crystal and exhibit high solubility. Radical cations obtained by one-electron oxidation of these derivatives gave stable radical cations in solution and showed absorption in the near-infrared region. A radical cation was isolated as a stable salt, which exhibited heat resistance up to around 200 °C. A design strategy for radical cation-based near-infrared absorbing dyes, which are easily oxidized and stable not only as a solution but in solid form, is described.

kn-title=Mechanistic Insights Into Oxidative Response of Heat Shock Factor 1 Condensates
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Heat shock factor 1 (Hsf1), a hub protein in the stress response and cell fate decisions, senses the strength, type, and duration of stress to balance cell survival and death through an unknown mechanism. Recently, changes in the physical property of Hsf1 condensates due to persistent stress have been suggested to trigger apoptosis, highlighting the importance of biological phase separation and transition in cell fate decisions. In this study, the mechanism underlying Hsf1 droplet formation and oxidative response was investigated through 3D refractive index imaging of the internal architecture, corroborated by molecular dynamics simulations and biophysical/biochemical experiments. We found that, in response to oxidative conditions, Hsf1 formed liquid condensates that suppressed its internal mobility. Furthermore, these conditions triggered the hyper-oligomerization of Hsf1, mediated by disulfide bonds and secondary structure stabilization, leading to the formation of dense core particles in the Hsf1 droplet. Collectively, these data demonstrate how the physical property of Hsf1 condensates undergoes an oxidative transition by sensing redox conditions to potentially drive cell fate decisions.

kn-title=Hydrogen Embrittlement Characteristics of Austenitic Stainless Steels After Punching Process
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study investigates the influence of microstructural characteristics on the hydrogen embrittlement of SUS304 austenitic stainless steel. The investigation utilized SUS304 sheets with a thickness of 1.5 mm, which were processed by punching with an 8 mm diameter to make specimens. Severe plastic deformation was localized near the punching edge, with the extent of deformation determined by the punching speed. Slower punching speeds induced more pronounced plastic strain, which was closely associated with work hardening and strain-induced martensitic (SIM) transformation. The SIM phase was predominantly observed within a depth of approximately 0.1 mm from the punched edge when processed at a punching speed of 0.25 mm/s, corresponding to roughly 10% of the cross-sectional area of the sample. These microstructural changes led to a significant reduction in tensile and fatigue strength, thereby exacerbating susceptibility to severe hydrogen embrittlement, despite the limited extent of microstructural alteration. Based on these findings, a modified Goodman diagram for SUS304 austenitic stainless steel, incorporating mechanical properties and hydrogen embrittlement behavior, was proposed.

kn-title=Method for predicting crack size using amplitude change in titanium alloy under bending vibration
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The natural frequency of a material decreases owing to the presence of cracks. Thus, when a crack initiates in a material under vibration, the amplitude of the vibration changes with the crack propagation. In this study, we investigated a method for predicting crack size using the amplitude change in a plate specimen of a titanium alloy under bending vibration. The bending displacement amplitudes were measured using high-speed camera images of the specimens. The crack sizes were measured using optical microscopy images of plastic replicas of the specimen surfaces that were obtained after interrupting tests at specified intervals. By using the relationship between the total area of the cracks and bending displacement amplitude for tests at two different vibration frequencies as well as the relationship between the vibration frequency and bending displacement amplitude for an undamaged specimen, the bending displacement amplitude at any vibration frequency can be monitored to predict the total area of the cracks.

kn-title=Study of the Mechanical Properties of Al?Mg ADC6 Aluminum Alloy Produced by Unidirectional Casting Under Various Cooling Rates
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=To create the high strength and high ductility of Al?Mg-based aluminum alloy (JIS?ADC6), ADC6 samples were produced by the unidirectional continuous casting (HMC). The HMC process was conducted with direct water cooling to melt ADC6, which can make fine microstructures and control crystal orientation. The cast samples were prepared under various cooling rates (CRs): 6.3, 34, and 62 K/s. The microstructure and crystal orientation of the samples were altered with CR. At CRs of 34 K/s and 62 K/s, the α-Al phases and intermetallic compounds, e.g., Mg2Si and Al15(Fe, Mn)3Si2, became finer and more spherical. The secondary dendrite arm spacing for the sample at 62 K/s was 8.7 ?m?more than 70% smaller than the ADC6 sample (ingot) made by a gravity casting process. Notably, at a CR of 34 K/s, the crystal orientation was predominantly arranged with the (101) plane. Tensile properties?ultimate tensile strength (σUTS), 0.2% proof stress (σ0.2), and failure strain (εf)?varied with the CR. The tensile strength (σUTS and σ0.2) consistently increased with increasing the CR. The improvement in the tensile strength resulted from the refined microstructures, such as the α-Al phase and intermetallic compounds. Similarly, the failure strain also increased with increasing CR, which was severely affected by the finer and more spherical intermetallic compounds. In this case, the εf value of the sample at 34 K/s was, however, slightly higher than that at 62 K/s, due to more uniformly organized crystal orientation, while their ductility was much higher than that of the gravity cast sample. The tensile properties in detail were further analyzed using their failure characteristics.

kn-title=Droplet Transportation on Janus Harp Wires for Enhanced Fog Harvesting
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Ensuring freshwater resources is a vital issue for human beings worldwide. Fog harvesting is one promising way to provide water from unconventional sources. However, clogging by the captured liquid depresses the fog harvesting performance. Here, a harp-shaped Janus harvesting system, which has thin wires with a superhydrophobic side facing the fog stream and a superhydrophilic back side to transport the droplets, is used to yield simultaneous fog capturing and water transport abilities. Attached droplets on the Janus wire transported along the periphery avoided clogging and enhanced the performance. The Janus system thus suppressed the increase and fluctuations of actual shade coefficients, which indicated blockage of the fog stream. This optimized the design of the harvester. Experiments using a multilayered Janus harvester demonstrated a significant enhancement compared with that constructed with mono-wettability wires. Overall, the results indicated the promise of droplet transportation on single wires for improving fog harvesting, as well as for other applications such as oil mist recovery and demulsification.

kn-title=Tailoring Mechanical Properties and Ionic Conductivity of Poly(ionic liquid)-Based Ion Gels by Tuning Anion Compositions
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Poly(ionic liquid) (PIL)-based ion gels have emerged as promising materials for advanced electrochemical applications because of their excellent miscibility with ionic liquids (IL), tunable mechanical properties, and high ionic conductivity. Despite extensive studies on PIL-based ion gels, a comprehensive understanding of how different anion combinations in the system affect physicochemical properties is lacking. In this study, we systematically investigate the effect of different anion species, such as bis(trifluoromethanesulfonyl)imide (TFSI) and hexafluorophosphate (PF6), on the mechanical, viscoelastic, and ion conductive behaviors of PIL-based ion gels. We investigate the interplay between anion size, packing density, and polymer segmental dynamics by varying the anion composition in both the PIL network and IL component. Rheological analysis and uniaxial tensile testing results indicate that PF6-containing ion gels exhibit enhanced higher Young’s modulus because of their restricted chain mobility resulting in higher glass transition temperature (Tg). In addition, we confirm the anion exchange between PIL and IL during gel preparation and find that the mechanical and ion conductive properties of the gels are governed by the total molar ratio of anions in the gels. Our findings highlight that tuning the anion composition in PIL-based ion gels provides an effective strategy to tailor their performance, with potential applications for flexible electronics and solid-state electrochemical devices.

kn-title=Electrostatically‐Driven Collapse of Polyelectrolytes: The?Role of the Solvent's Dielectric Constant
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We experimentally confirm a longstanding theoretical prediction of counterion-induced
polyelectrolyte collapse in low dielectric media. The scattering behavior of polystyrene sulfonate in different solvents with dielectric permittivities in the range of ε ? 12 ? 180 is investigated. For high and intermediate ε media, typical polyelectrolyte behavior is observed: the correlation length (ξ) scales with concentration (c) as ξ ? c?1?2, as predicted by various theories. When the dielectric constant of the solvent decreases below ? 22, a scaling of ξ ? c?1?3, characteristic of partially collapsed polyelectrolytes, is observed. For these solvents, the correlation peak disappears at high concentrations. Interestingly, polyelectrolyte collapse is observed under both solvophilic and solvophobic conditions, supporting the existence of attractive electrostatic interactions. These results are in qualitative agreement with theoretical predictions which expect chain collapse in low dielectric media due to the influence of condensed counterions, either via dipolar attraction and/or charge-correlation-induced attractions.

kn-abstract=Graphene-based materials (GBMs) are of considerable interest for biomedical applications, and the pilot study on the toxicological and immunological impact of pristine graphene (GR) and graphene oxide (GO) using swine as a close-to-human provides valuable insights. First, ex vivo experiments are conducted on swine blood cells, then GBMs are injected intraperitoneally (i.p.) into swine. Hematological and biochemical analyses at various intervals indicate that neither GO nor GR cause systemic inflammation, pro-coagulant responses, or renal or hepatic dysfunction. Importantly, no systemic toxicity is observed. Analysis of a panel of 84 immune-related genes shows minimal impact of GO and GR. The animals are sacrificed 21 days post-injection, and transient absorption imaging and Raman mapping show the presence of GO and GR in the mesentery only. Histological evaluation reveals no signs of alterations in other organs. Thus, clusters of both materials are detected in the mesentery, and GO aggregates are surrounded only by macrophages with the formation of granulomas. In contrast, modest local reactions are observed around the GR clusters. Overall, these results reveal that i.p. injection of GBMs resulted in a modest local tissue reaction without systemic toxicity. This study, performed in swine, provides essential guidance for future biomedical applications of graphene.

kn-title=Light-Responsive and Antibacterial Graphenic Materials as a Holistic Approach to Tissue Engineering
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=While the continuous development of advanced bioprinting technologies is under fervent study, enhancing the regenerative potential of hydrogel-based constructs using external stimuli for wound dressing has yet to be tackled. Fibroblasts play a significant role in wound healing and tissue implants at different stages, including extracellular matrix production, collagen synthesis, and wound and tissue remodeling. This study explores the synergistic interplay between photothermal activity and nanomaterial-mediated cell proliferation. The use of different graphene-based materials (GBM) in the development of photoactive bioinks is investigated. In particular, we report the creation of a skin-inspired dressing for wound healing and regenerative medicine. Three distinct GBM, namely, graphene oxide (GO), reduced graphene oxide (rGO), and graphene platelets (GP), were rigorously characterized, and their photothermal capabilities were elucidated. Our investigations revealed that rGO exhibited the highest photothermal efficiency and antibacterial properties when irradiated, even at a concentration as low as 0.05 mg/mL, without compromising human fibroblast viability. Alginate-based bioinks alongside human fibroblasts were employed for the bioprinting with rGO. The scaffold did not affect the survival of fibroblasts for 3 days after bioprinting, as cell viability was not affected. Remarkably, the inclusion of rGO did not compromise the printability of the hydrogel, ensuring the successful fabrication of complex constructs. Furthermore, the presence of rGO in the final scaffold continued to provide the benefits of photothermal antimicrobial therapy without detrimentally affecting fibroblast growth. This outcome underscores the potential of rGO-enhanced hydrogels in tissue engineering and regenerative medicine applications. Our findings hold promise for developing game-changer strategies in 4D bioprinting to create smart and functional tissue constructs with high fibroblast proliferation and promising therapeutic capabilities in drug delivery and bactericidal skin-inspired dressings.

kn-title=Electrochemical Generation of Sulfonamidyl Radicals via Anodic Oxidation of Hydrogen Bonding Complexes: Applications to Electrosynthesis of Benzosultams
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Amidyl radicals and sulfonamidyl radicals are widely used in the field of organic synthesis. In particular, the electrochemical oxidation of amides in the presence of bases is one of the most practical methods for generating amidyl radicals. However, it is often difficult to observe the “true” radical precursor, such as an amide anion and/or a hydrogen bonding complex with an amide and a base. We found that a sulfonamide and Bu4NOAc form a 1:1 hydrogen bonding complex by spectroscopic experiments. Cyclic voltammetry suggested that 1:1 hydrogen bonding complexes should be oxidized predominantly under the optimized conditions to afford a sulfonamidyl radical via the proton-coupled electron transfer (PCET) process by the oxidation of the complex. Thus-generated sulfonamidyl radicals could be used in the electrochemical synthesis of a variety of benzosultams.

kn-title=Effects of Sediment Microbial Fuel Cells on CH4 and CO2 Emissions from Straw Amended Paddy Soil
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Straw returning into paddy soil enhances soil organic matter which usually promotes the emission of greenhouse gases to the atmosphere. The application of sediment microbial fuel cells (SMFCs) to paddy soil activates power-generating microorganisms and enhances organic matter biodegradation. In the present study, rice straw addition in SMFCs was examined to determine its effect on CH4 and CO2 emissions. Columns (height, 25?cm; inner diameter, 9?cm) with four treatments: soil without and with rice straw under SMFC and without SMFC conditions were incubated at 25°C for 70 days. Anodic potential values at 7?cm depth sediment were kept higher by SMFCs than those without SMFCs. Cumulative CH4 emission was significantly reduced by SMFC with straw amendment (p < 0.05) with no significant effect on CO2 emission. 16S rRNA gene analysis results showed that Firmicutes at the phylum, Closteridiales and Acidobacteriales at order level were dominant on the anode of straw-added SMFC, whereas Methanomicrobiales were in the treatment without SMFC, indicating that a certain group of methanogens were suppressed by SMFC. Our results suggest that the anodic redox environment together with the enrichment of straw-degrading bacteria contributed to a competitive advantage of electrogenesis over methanogenesis in straw-added SMFC system.

kn-title=Engineering Zeolitic-Imidazolate-Framework-Derived Mo-Doped Cobalt Phosphide for Efficient OER Catalysts
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Designing a cheap, competent, and durable catalyst for the oxygen evolution reaction (OER) is exceedingly necessary for generating oxygen through a water-splitting reaction. In this project, we have designed a ZIF-67-originated molybdenum-doped cobalt phosphide (CoP) using a simplistic dissolution?regrowth method using Na2MoO4 and a subsequent phosphidation process. This leads to the formation of an exceptional hollow nanocage morphology that is useful for enhanced catalytic activity. Metal?organic frameworks, especially ZIF-67, can be used both as a template and as a metal (cobalt) precursor. Molybdenum-doped CoP was fabricated through a two-step synthesis process, and the fabricated Mo-doped CoP showed excellent catalytic activity during the OER with a lower value of overpotential. Furthermore, the effect of the Mo amount on the catalytic activity has been explored. The best catalyst (CoMoP-2) showed an onset potential of around 1.49 V at 10 mA cm?2 to give rise to a Tafel slope of 62.1 mV dec?1. The improved catalytic activity can be attributed to the increased porosity and surface area of the resultant catalyst.

kn-title=Grafting-through functionalization of graphene oxide with cationic polymers for enhanced adsorption of anionic dyes and viruses
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Graphene oxide (GO) is a sheet-like carbon material with abundant oxygen-containing functional groups on its surface. GO has been extensively studied as an adsorbent for heavy metals and organic compounds. However, effective strategies for negatively charged materials have yet to be established. This study aimed to synthesize composites of GO and cationic polymers for the selective adsorption of negatively charged materials; a challenge in this approach is the strong electrostatic interactions between GO and cationic polymers, which can lead to aggregation. This study addresses this issue by employing the grafting-through method. GO was initially modified with allylamine to introduce a polymerizable site, followed by radical polymerization to covalently bond polymers to the GO surface, effectively preventing aggregation. Adsorption experiments demonstrated that the GO-polymer composite selectively adsorbs anionic dye, such as methyl orange. Virus adsorption tests showed significantly enhanced performance compared to pristine GO. These results emphasize the critical role of controlled surface modification and charge manipulation in optimizing the adsorption performance of GO. This study establishes a simple and effective approach for synthesizing GO-cationic polymer composites, contributing to the development of advanced materials for water purification applications.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Oxidized carbon materials have abundant surface functional groups and customizable properties, making them an excellent platform for generating radicals. Unlike reactive oxygen species such as hydroxide or superoxide radicals that have been reported previously, oxidized carbon also produces stable carbon radicals under photo-irradiation. This has been confirmed through electron spin resonance. Among the various oxidized carbon materials synthesized, graphene oxide shows the largest number of carbon radicals when exposed to blue LED light. The light absorption capacity, high surface area, and unique structural characteristics of oxidized carbon materials offer a unique function for radical-mediated oxidative reactions.

kn-title=RKPM: Restricted Kernel Page Mechanism to?Mitigate Privilege Escalation Attacks
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Kernel memory corruption attacks against operating systems exploit kernel vulnerabilities to overwrite kernel data. Kernel address space layout randomization makes it difficult to identify kernel data by randomizing their virtual address space. Control flow integrity (CFI) prevents unauthorized kernel code execution by verifying kernel function calls. However, these countermeasures do not prohibit writing to kernel data. If the virtual address of privileged information is specified and CFI is circumvented, the privileged information can be modified by a kernel memory corruption attack. In this paper, we propose a restricted kernel page mechanism (RKPM) to mitigate kernel memory corruption attacks by introducing restricted kernel pages to protect the kernel data specified in the kernel. The RKPM focuses on the fact that kernel memory corruption attacks attempt to read the virtual addresses around the privileged information. The RKPM adopts page table mapping handling and a memory protection key to control the read and write restrictions of the restricted kernel pages. This allows us to mitigate kernel memory corruption attacks by capturing reads to the restricted kernel page before the privileged information is overwritten. As an evaluation of the RKPM, we confirmed that it can mitigate privilege escalation attacks on the latest Linux kernel. We also measured that there was a certain overhead in the kernel performance. This study enhances kernel security by mitigating privilege escalation attacks through the use of software or hardware based restricted kernel pages.

kn-title=kdMonitor: Kernel Data Monitor for Detecting Kernel Memory Corruption
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Privilege escalation attacks through memory corruption via kernel vulnerabilities pose significant threats to operating systems. Although the extended Berkley Packet Filter has been employed to trace kernel code execution by inserting interrupts before and after kernel code invocations, it does not track operations before and after kernel data writes, thus hindering effective kernel data monitoring. In this study, we introduce a kernel data monitor (kdMonitor), which is a novel security mechanism designed to detect unauthorized alterations in the monitored kernel data of a dedicated kernel page. The kdMonitor incorporates two distinct methods. The first is periodic monitoring which regularly outputs the monitored kernel data of the dedicated kernel pages. The second is dynamic monitoring, which restricts write access to a dedicated kernel page, supplements any write operations with page faults, and outputs the monitored kernel data of dedicated kernel pages. kdMonitor enables real-time tracking of specified kernel data of the dedicated kernel page residing in the kernel's virtual memory space from the separated machine. Using kdMonitor, we demonstrated its capability to pinpoint tampering with user process privileged information stemming from privilege escalation attacks on the kernel. Through an empirical evaluation, we validated the effectiveness of kdMonitor in detecting privilege escalation attacks by user processes on Linux. Performance assessments revealed that kdMonitor achieved an attack detection time of 0.83 seconds with an overhead of 0.726 %.

kn-title=vkTracer: Vulnerable Kernel Code Tracing to?Generate Profile of?Kernel Vulnerability
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Vulnerable kernel codes are a threat to an operating system kernel. An adversary’s user process can forcefully invoke a vulnerable kernel code to cause privilege escalation or denial of service (DoS). Although service providers or security operators have to determine the effect of kernel vulnerabilities on their environment to decide the kernel updating, the list of vulnerable kernel codes are not provided from the common vulnerabilities and exposures (CVE) report. It is difficult to identify the vulnerable kernel codes from the exploitation result of the kernel which indicates the account information or the kernel suspension. To identify the details of kernel vulnerabilities, this study proposes a vulnerable kernel code tracer (vkTracer), which employs an alternative viewpoint using proof-of-concept (PoC) code to create a profile of kernel vulnerability. vkTracer traces the user process of the PoC code and the running kernel to hook the invocation of the vulnerable kernel codes. Moreover, vkTracer extracts the whole kernel component’s information using the running and static kernel image and debug section. The evaluation results indicated that vkTracer could trace PoC code executions (e.g., privilege escalation and DoS), identify vulnerable kernel codes, and generate kernel vulnerability profiles. Furthermore, the implementation of vkTracer revealed that the identification overhead ranged from 5.2683 s to 5.2728 s on the PoC codes and the acceptable system call latency was 3.7197 μs.

kn-title=Recent progress on phenothiazine organophotoredox catalysis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Photoredox catalysis has garnered significant attention in recent years due to its broad applicability in visible-light-induced organic transformations. While significant progress has been made in the development of highly oxidizing catalysts, such as acridinium catalysts, there remains a notable shortage of strongly reducing organophotoredox catalysts. Phenothiazines are widely used as photoredox catalysts owing to their unique redox potentials, particularly their low excited-state oxidation potentials (Eox* = ?1.35 V to ?3.51 V vs. SCE). Thus, they can be applied to a variety of photoredox reactions with oxidative-quenching cycles, and effectively reduce various organic molecules, such as aryl and alkyl halides, alkenes, malonyl peroxides, cobalt complexes, and redox-active esters. Due to their unique properties, this review focuses on the recent advances in phenothiazine organophotoredox catalysis.

kn-title=Microagglomerate of VO2 Particles Packing Paraffin Wax Using Capillary Force as a Latent Thermal Energy Storage Medium
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study proposed a material to retain paraffin wax with vanadium dioxide (VO2) particles as a latent thermal energy storage medium, an alternative to core?shell microcapsules containing phase change materials. VO2 microparticles, which were synthesized through a sol?gel method and annealing process, were dispersed in the oil-in-water microemulsion to obtain microagglomerates of VO2 microparticles. The average diameter of microagglomerates was 5 μm, and they retained paraffin wax at the vacancies among VO2 particles. Although the microagglomerates had no complete shells similar to core?shell microcapsules, the microagglomerates successfully trapped paraffin wax droplets without any leakage even in a high-temperature environment. It was because capillary forces acting among VO2 particles strictly prevented any leakage of paraffin waxes. The differential scanning calorimetry revealed that the microagglomerates contained only 16.5 wt % of n-octadecane, used as a paraffin wax. However, since VO2 particles can release or absorb latent heat due to their metal?insulator phase transition, the proposed microagglomerates exhibited higher thermal energy storage densities than phase change microcapsules whose shells do not show phase transitions. Moreover, the microagglomerates exhibited higher thermal conductivity than microcapsules with amorphous inorganic shells because the VO2 particles were crystallized through annealing. The proposed microagglomerate is a promising form for further improving the thermal energy storage density and thermal performance of the latent thermal energy storage medium, especially in the temperature range of 30 to 70 °C.

kn-title=Collective motions in the primary coordination sphere: a critical functional framework for catalytic activity of the oxygen-evolving complex of photosystem II
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Photosynthetic water oxidation, vital for dioxygen production and light energy conversion, is catalyzed by the oxygen-evolving complex of photosystem II, where the inorganic Mn4CaO5 cluster acts as the catalytic core. In this study, we investigate the functional significance of collective motions of amino acid side chains within the primary coordination sphere of the Mn cluster, focusing on their role in modulating the energetic demands for catalytic transformations in the S3 state. We applied regularized canonical correlation analysis to quantitatively correlate the three-dimensional arrangement of coordinating atoms with catalytic driving forces computed via density functional theory. Our analysis reveals that distinct collective side chain motions profoundly influence the energetic requirements for structural reconfigurations of the Mn cluster, achieved through expansion and contraction of the ligand cavity while fine-tuning its geometry to stabilize key intermediates. Complementary predictions from a neural network-based machine learning model indicate that the coordination sphere exerts a variable energetic impact on the catalytic transformations of the Mn cluster, depending on the S-state environment. Integrated computational analyses suggest that the extended lifetime of the S3YZ? state, consistently observed after three flash illuminations, may result from slow, progressive protein dynamics that continuously reshape the energy landscape, thereby shifting the equilibrium positions of rapid, reversible chemical processes over time. Overall, our findings demonstrate that collective motions in the primary coordination sphere constitute an active, dynamic framework essential for the efficient execution of multi-electron catalysis under ambient conditions, while simultaneously achieving a high selectivity with irreversible nature required for effective 3O2 evolution.

kn-title=Effect of temperature cycles on the sleep-like state in Hydra vulgaris
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Sleep is a conserved physiological phenomenon across species. It is mainly controlled by two processes: a circadian clock that regulates the timing of sleep and a homeostat that regulates the sleep drive. Even cnidarians, such as Hydra and jellyfish, which lack a brain, display sleep-like states. However, the manner in which environmental cues affect sleep-like states in these organisms remains unknown. In the present study, we investigated the effects of light and temperature cycles on the sleep-like state in Hydra vulgaris.<br>
Results Our findings indicate that Hydra responds to temperature cycles with a difference of up to 5° C, resulting in decreased sleep duration under light conditions and increased sleep duration in dark conditions. Furthermore, our results reveal that Hydra prioritizes temperature changes over light as an environmental cue. Additionally, our body resection experiments show tissue-specific responsiveness in the generation ofthe sleep-like state under different environmental cues. Specifically, the upper body can generate the sleep-like state in response to a single environmental cue. In contrast, the lower body did not respond to 12-h light?dark cycles at a constant temperature.<br>
Conclusions These findings indicate that both light and temperature influence the regulation of the sleep-like state in Hydra. Moreover, these observations highlight the existence of distinct regulatory mechanisms that govern patterns of the sleep-like state in brainless organisms, suggesting the potential involvement of specific regions for responsiveness of environmental cues for regulation of the sleep-like state.

kn-title=A high-protein diet-responsive gut hormone regulates behavioral and metabolic optimization in Drosophila melanogaster
en-subtitle=

en-abstract=
kn-abstract=Protein is essential for all living organisms; however, excessive protein intake can have adverse effects, such as hyperammonemia. Although mechanisms responding to protein deficiency are well-studied, there is a significant gap in our understanding of how organisms adaptively suppress excessive protein intake. In the present study, utilizing the fruit fly, Drosophila melanogaster, we discover that the peptide hormone CCHamide1 (CCHa1), secreted by enteroendocrine cells in response to a high-protein diet (HPD), is vital for suppressing overconsumption of protein. Gut-derived CCHa1 is received by a small subset of enteric neurons that produce short neuropeptide F, thereby modulating protein-specific satiety. Importantly, impairment of the CCHa1-mediated gut-enteric neuronal axis results in ammonia accumulation and a shortened lifespan under HPD conditions. Collectively, our findings unravel the crosstalk of gut hormone and neuronal pathways that orchestrate physiological responses to prevent and adapt to dietary protein overload.

kn-title=Neurotransmitter and Receptor Mapping in Drosophila Circadian Clock Neurons via T2A-GAL4 Screening
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The circadian neuronal network in the brain comprises central pacemaker neurons and associated input and output pathways. These components work together to generate coherent rhythmicity, synchronize with environmental time cues, and convey circadian information to downstream neurons that regulate behaviors such as the sleep/wake cycle. To mediate these functions, neurotransmitters and neuromodulators play essential roles in transmitting and modulating signals between neurons. In Drosophila melanogaster, approximately 240 brain neurons function as clock neurons. Previous studies have identified several neurotransmitters and neuromodulators, including the Pigment-dispersing factor (PDF) neuropeptide, along with their corresponding receptors in clock neurons. However, our understanding of the neurotransmitters and receptors involved in the circadian system remains incomplete. In this study, we conducted a T2A-GAL4-based screening for neurotransmitter and receptor genes expressed in clock neurons. We identified 2 neurotransmitter-related genes and 22 receptor genes. Notably, while previous studies had reported the expression of 6 neuropeptide receptor genes in large ventrolateral neurons (l-LNv), we also found that 14 receptor genes?including those for dopamine, serotonin, and γ-aminobutyric acid?are expressed in l-LNv neurons. These findings suggest that l-LNv neurons serve as key integrative hubs within the circadian network, receiving diverse external signals.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this study, we developed microfluidic paper-based analytical devices (μPADs) for the determination of antioxidant vitamins. The proposed μPADs utilize the reduction of metal ions by hydrophilic and hydrophobic antioxidant vitamins, which is followed by colorimetric reactions with chelating reagents. Hydrophilic vitamin C reduces Fe(III) to Fe(II) and forms a stable Fe(II)-bathophenanthroline complex in an aqueous solution. By contrast, this complex is unstable in organic solvents, and hydrophobic vitamin E requires Fe(III) and bathophenanthroline to be replaced with Cu(II) and bathocuproine. In these results, the relationship between the logarithm of a vitamin's concentration and its color intensity was linear and ranged from 4.4 to 35 mg L?1 for ascorbic acid and 50?200 mg L?1 for α-tocopherol. The limits of detection, estimated from the standard deviation of blank samples, were 3.1 mg L?1 for ascorbic acid and either 27 mg L?1 (in hexane) or 48 mg L?1 (in ethanol) for α-tocopherol. The proposed method was used to quantify vitamin C in bell peppers, mandarin oranges, kiwifruit, and lemons, as well as vitamin E in almonds, almond milk, and dietary supplements. The results demonstrate the effectiveness of these μPADs for the practical analysis of antioxidant vitamins in food samples.

kn-title=Innovations in paper-based analytical devices and portable absorption photometers for onsite analysis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Two types of analytical instruments and devices?one sophisticated high-performance instrument and another portable device?have been the focus of recent trends in analytical science. The necessity of point-of-care testing and onsite analysis has accelerated the advancement of high-performance, user-friendly portable analytical devices such as paper-based analytical devices (PADs) and light-emitting diode-based portable photometers. In this review, we summarize our achievements in the study of PADs and portable photometers. Several types of PADs are capable of performing titrations, metal ion analysis, and food analysis, while photometers, which consist of paired emitter?detector light-emitting diode (PEDD) photometers, are used for thiocyanate and herbicide analysis. These PADs and photometers permit the onsite determination of real environmental, body fluid, and food samples when an equipped laboratory is unavailable.

kn-title=Oxytocin facilitates human touch-induced play behavior in rats
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Pleasant touch sensations play a fundamental role in social bonding, yet the neural mechanisms underlying affinity-like behaviors remain poorly understood. Here, we demonstrate that juvenile-adolescent rats, which naturally engage in social play with peers characterized by rough-and-tumble interactions and 50 kHz ultrasonic vocalizations indicating pleasant sensations, develop a strong affinity for human hands through similar playful contact achieved by repeated tickling with human hands. Using this rat with tickling-induced high affinity for human hands, we discovered that repeated tickling mimicking rough-and-tumble play led to increased oxytocin receptor (OTR) expression in the ventrolateral part of the ventromedial hypothalamus (VMHvl). Inhibition of oxytocin signaling in the VMHvl reduced affinity-like behaviors from rats to human hands. These findings suggest that OTR neurons in VMHvl play an important role in the increase in affinity for human hands induced by pleasant touch sensation with human touch-induced play behavior. Based on retrograde and anterograde tracing studies examining the supraoptic nucleus (SON) and the paraventricular nucleus (PVN) as primary sources of oxytocin, we demonstrate that a subset of oxytocin fibers in the VMHvl originate from the SON, suggesting that affinity-like behavior from rats to human hands may be controlled by oxytocin signaling from magnocellular neurons. Together, this work advances our understanding of how oxytocin shapes social behavior and may inform the development of therapeutic strategies to promote positive social interactions.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=mRNA has great potential for therapeutic applications because it can encode a variety of proteins and antigens, in addition to advantages over DNA in terms of gene expression without genomic integration, nuclear localization, or transcription. However, therapeutic applications of mRNA require safe and effective delivery into target cells. Therefore, we aimed to investigate photochemical internalization (PCI) as a promising strategy for delivering mRNA to target cells. In this strategy, mRNA is taken up into cells by endocytosis, accumulates in endosomes, and is released in a light-dependent manner from the endosomes using an endosome-accumulating photosensitizer, aluminum phthalocyanine disulfonate (AlPcS2a), in combination with nucleic acid carrier molecules. We compared the efficacy of various nucleic acid carriers, including branched polyethyleneimine (bPEI) and poly{N'-[N-(2-aminoethyl)-2-aminoethyl] aspartamide} (PAsp(DET)) under the same conditions for PCI-based mRNA delivery. Our results indicated that bPEI and PAsp(DET) at low N/P ratios exhibited efficient light-enhancement of mRNA expression by PCI with AlPcS2a. Notably, bPEI exhibited the highest light-dependent mRNA delivery among the carriers evaluated (including cationic polymers, cationic peptides, and lipids), whereas PAsp(DET) showed promise for clinical use because of its lower toxicity compared with bPEI. This PCI strategy allows effective cytosolic mRNA delivery at low N/P ratios, thereby reducing cationic carrier molecule-induced cytotoxicity. This method allows spatiotemporal control of protein expression and holds potential for novel light-dependent mRNA therapies. Overall, this study provided valuable insights into optimizing mRNA delivery systems for therapeutic applications.

kn-abstract=The granulation process of a slurry droplet containing a water-soluble polymer in a spray dryer is investigated. Although there have been many studies on the drying behavior of a single-component slurry droplet, there have been few reports for a multicomponent slurry droplet. This is due to the complexity and difficulty in evaluating the drying behavior of a multicomponent slurry droplet. Therefore, for the production of granules from multicomponent materials by a spray dryer, its operating conditions are usually determined by trial and error. To optimize the practical granule production process, the drying behavior of multicomponent slurry droplets should be studied. In this study, the drying behavior of a silica slurry droplet containing polyvinyl alcohol (PVA) is investigated. The drying behavior of a droplet suspended on the tip of a needle was observed. The effect of the volume fraction of PVA on the drying behavior and the morphology of a dried granule is studied. The effect of drying condition on the granule formation process is also investigated. As a result, the structure of dried granules was strongly influenced by PVA concentration. Segregation of PVA in the dried granules was observed. Based on the results, the drying process diagram is presented.

kn-title=Development of a Vinylated Cyclic Allene: A Fleeting Strained Diene for the Diels?Alder Reaction
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Fleeting molecules possessing strained multiple bonds are important components in organic synthesis due to their ability to undergo various chemical reactions driven by the release of strain energy. Although the use of strained π-bonds as 2π components, represented by dienophiles in Diels?Alder reactions, has been well studied, “the strained diene (4π component) approach” for molecular construction remains underexplored. Herein, we report the design of a vinyl cyclic allene (1-vinyl-1,2-cyclohexadiene) as a highly reactive strained diene and the development of its Diels?Alder reactions. Experimental and computational studies of vinyl cyclic allenes revealed that this diene system undergoes cycloaddition with dienophiles regio- and stereoselectively under mild reaction conditions. These studies also provide insight into the reactivity and selectivity of the system. The strained diene approach enables the convergent construction of polycyclic molecules through bond disconnections distinct from conventional retrosynthetic analysis, thus offering an efficient strategy for the assembly of functional molecules.

kn-title=Towards SBOM-based Access Control for Transparent and Explicit Program Execution
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Although a Software Bill of Materials (SBOM) plays a key role in software transparency, inconsistencies in SBOM descriptions can undermine its value. To address this, we propose a novel approach to program access control, SBOMAC, which leverages Mandatory Access Control (MAC) systems to ensure transparent and explicit program execution. In this study, we identify the challenges associated with implementing this approach and present preliminary investigation results to address these challenges.

kn-title=ボールエンドミルの突き出し長さに応じた切削条件補正システムの開発
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In the field of die and mold machining, determining appropriate cutting conditions is crucial. Factors such as tool geometry, machining path, work material characteristics, machining efficiency, and finishing accuracy must be taken into consideration. However, the current method of determining cutting conditions relies heavily on the intuition and experience of skilled engineers, and there is a need for a system to replace such knowledge. One of the critical factors affecting machining accuracy and efficiency is the tool overhang length, which is directly related to tool geometry. Unfortunately, there is no clear guideline for its determination. In a previous study, researchers developed a system to quickly derive cutting conditions using a data mining method and Random Forest Regression (RFR) applied to a tool catalog database. In this study, we constructed a new cutting condition compensation system based on the existing model, which accounts for the tool overhang length. The results of cutting experiments under high aspect ratio overhang lengths confirm that the correction coefficients proposed by the system are significant.

kn-title=Study on the Grinding Temperature of Workpiece in Side Plunge Grinding Process
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Grinding is used to finish thrust metal attachment parts, such as crankshafts, which have both journal and thrust surfaces. In side plunge grinding, a thrust surface and a cylindrical surface of a shaft workpiece with collars are finished in a single plunge grinding process. However, the surface quality near the ground internal corner, where grinding fluid may not penetrate, can deteriorate, causing high residual stress and cracks owing to grinding heat. While it has been reported that quality issues at the inner corners of the ground surface can be mitigated by reducing the grinding point temperature through efficient cooling fluid supply, the mechanisms of grinding phenomena and heat generation in side plunge grinding are not yet fully understood. In this study, the variations in the grinding temperature at the thrust surface of a workpiece with a collar were experimentally investigated using a wire/workpiece thermocouple to clarify these phenomena. The results revealed a significant increase in the grinding temperature at the corners of the grinding zone. However, it slightly decreases as the thermocouple output approaches the center of the workpiece, indicating a slight effect of the grinding speed. The surface temperature of the workpiece in side plunge grinding is primarily influenced by the wheel depth-of-cut in the thrust direction. Additionally, the effect of workpiece rotational speed and grinding infeed speed on temperature distribution has been demonstrated.

kn-title=CyNER: Information Extraction from?Unstructured Text of?CTI Sources with?Noncontextual IOCs
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Cybersecurity threats have been increasing and growing more sophisticated year by year. In such circumstances, gathering Cyber Threat Intelligence (CTI) and following up with up-to-date threat information is crucial. Structured CTI such as Structured Threat Information eXpression (STIX) is particularly useful because it can automate security operations such as updating FW/IDS rules and analyzing attack trends. However, as most CTIs are written in natural language, manual analysis with domain knowledge is required, which becomes quite time-consuming.<br>
In this work, we propose CyNER, a method for automatically structuring CTIs and converting them into STIX format. CyNER extracts named entities in the context of CTI and then extracts the relations between named entities and IOCs in order to convert them into STIX. In addition, by using key phrase extraction, CyNER can extract relations between IOCs that lack contextual information, such as those listed at the bottom of a CTI, and named entities. We describe our design and implementation of CyNER and demonstrate that it can extract named entities with the F-measure of 0.80 and extract relations between named entities and IOCs with the maximum accuracy of 81.6%. Our analysis of structured CTI showed that CyNER can extract IOCs that are not included in existing reputation sites, and that it can automatically extract IOCs that have been exploited for a long time and across multiple attack groups. CyNER is thus expected to contribute to the efficiency of CTI analysis.

kn-title=Analyzing Post-injection Attacker Activities in IoT Devices: A Comprehensive Log Analysis Approach
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=With the continuous proliferation of Internet of Things (IoT) devices, malware threats that specifically target these devices continue to increase. The urgent need for robust security measures is predicated on a comprehensive understanding of the behavioral patterns of IoT malware. However, previous studies have often overlooked the analysis of command sequences in Telnet logs. This study bridges this research gap by examining the post-injection behaviors of attackers. By analyzing a vast dataset comprising more than ten million logs collected from an IoT honeypot, we reveal three distinct post-injection activity patterns, each with unique characteristics. These patterns provide pivotal insights that not only help distinguish between legitimate operations and attempted attacks, but also drive the development of robust cybersecurity measures that effectively deter such behaviors. The nuances discovered in this study contribute significantly to IoT security by enhancing our understanding of malware tactics and informing targeted defense strategies.

kn-abstract=TEE systems provide normal world and secure world. It is impossible to gain access to the secure world directly from the normal world. However, vulnerabilities in the secure world can cause attacks to compromise the secure world. In this study, we investigate the security features applied to trusted applications (TA) in OP-TEE and clarify the lack of protection against stack buffer overflow in TA command calls. We also propose a method for preventing attacks that exploit stack buffer overflows in TA command calls. In addition, the experimental results show that attacks on the vulnerable TAs can be prevented with the proposed method and the overhead can be evaluated.

kn-title=Evaluation of Effectiveness of MAC Systems Based on LSM for Protecting IoT Devices
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Numerous active attacks targeting Internet of Things (IoT) devices exist. They exploit the latest vulnerabilities discovered in IoT devices. Therefore, Mandatory Access Control (MAC) systems based on Linux Security Modules (LSM), such as SELinux and AppArmor, are effective security features for IoT devices because they can mitigate the impact of attacks even if software vulnerabilities are discovered. However, they are not adopted by most IoT devices. The existing approaches are insufficient for investigating the causes of this problem.In this study, we comprehensively investigated what factors can affect the applicability of MAC systems based on LSM in IoT devices. We focused on how frequently cases can occur where they cannot be adopted, owing to each factor. To increase the comprehensiveness of the factors affecting the adoption of MAC systems in IoT devices, we investigated the kernel version, CPU architecture, and support for BusyBox in addition to the investigation of resources, which conducted in previous studies. We also conducted simulated experiments based on the attack method of Mirai to investigate whether MAC systems can protect against IoT malware. Finally, we discuss the impact of a combination of these factors on MAC system adoption.

kn-title=Non Real-Time Data Transmission Performance Analysis of PROFINET for Assuring Data Transmission Quality
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The industrial Ethernet PROFINET supports three different data transmission modes: isochronous real-time (IRT), real-time (RT), and non real-time (NRT) transmitting data requiring hard, soft, and no real-time performances, respectively. The data transmission latency in the NRT increased with the amount of data transmission in the IRT, RT, and NRT. Therefore, the quality of data transmission in NRT may degrade as the amount of data transmission in IRT, RT, and NRT increases. In this study, we derived the average data transmission latency in an NRT with data transmission in IRT and RT by applying stochastic processes. This allowed us to maintain the quality of data transmission in the NRT by adjusting the number of devices connected to the network and the number of applications transmitting data in the NRT so that the average latency of data in the NRT does not exceed a certain value.

kn-title=Supporting Multiple OS Types on Estimation of System Call Hook Point by Virtual Machine Monitor
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Methods to hook system calls issued by a guest operating system (OS) running on a virtual machine using a virtual machine monitor are proposed. The address of the hook point is derived from the guest OS’s source code and established prior to the kernel startup process. Due to changes in system call processing in OS updates and address space layout randomization, the addresses of these hook points cannot always be pre-determined before the kernel startup process. To address this challenge, a method for estimating the system call hook point is proposed in Linux by analyzing the guest OS memory on x86-64 CPUs rather than pre-calculation. Although the method supports Linux, the method can be extended to support other OS types. In this paper, we propose a method to extend the method to support additional OSes. Specifically, we present analysis results and a novel method for estimating hook points on FreeBSD, NetBSD, and OpenBSD. The effectiveness of our proposed method is also demonstrated through evaluation.

kn-title=Investigation Towards Detecting Landing Websites for?Fake Japanese Shopping Websites
en-subtitle=

en-abstract=
kn-abstract=Recently, the number of victims of fake shopping websites that imitate legitimate ones to defraud people has been increasing. It has been shown that fake shopping websites use legitimate defaced landing websites as their leading paths. Therefore, if the detection of landing websites for fake shopping websites can be achieved, it can assist in addressing these websites and reduce the opportunities for users to be redirected to fake shopping websites. In this study, we collect and investigate existing landing websites that redirect users to fake Japanese shopping websites and identify effective features for detecting them. We identified effective search terms for collecting landing websites for fake Japanese shopping websites and found that using Google searches with queries of top-level domain and product names was effective. We also investigated the conditions for activating analytical evasion functions in the collected landing websites for fake Japanese shopping websites and clarified the differences in search results between crawlers and users.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=An electrochemical method was developed to convert α,β-unsaturated aldehydes into carboxylic acid derivatives via cyanosilylation, isomerization, and nucleophilic addition. This reaction is more sustainable than the usual electrochemical organic reaction because this reaction proceeds catalytically with active species generated by a very small amount of electricity. Furthermore, scale-up synthesis with a flow reactor has been achieved.

kn-title=Neuromedin U Deficiency Disrupts Daily Testosterone Fluctuation and Reduces Wheel-running Activity in Rats
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The objective of this study was to elucidate the role of endogenous Neuromedin U (NMU) in rats by performing NMU knockout (KO). Male, but not female NMU KO rats exhibited decreased wheel-running activity vs wildtype (WT), although overall home cage activity was not affected. Plasma testosterone in WT rats varied significantly over the course of a day, with a peak at ZT1 and a nadir at ZT18, whereas in NMU KO rats testosterone remained stable throughout the day. Chronic administration of testosterone restored wheel-running activity in NMU KO rats to the same level as in WT rats, suggesting that the decrease in wheel-running activity in NMU KO rats is due to the disruption of the diurnal change of testosterone. Accordingly, expression of the luteinizing hormone beta subunit (Lhb) mRNA in the pars distalis of anterior pituitary was significantly lower in NMU KO rats; immunostaining revealed that the size of luteinizing hormone (LH)?expressing cells was also relatively small in those animals. In the brain of male WT rats, Nmu was highly expressed in the pars tuberalis, and the NMU receptor Nmur2 was highly expressed in the ependymal cell layer of the third ventricle. This study reveals a novel function of NMU and indicates that endogenous NMU in rats plays a role in the regulation of motivated activity via regulation of testosterone.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Layered materials have unique structures that can be modified by adjusting the space between layers through pillaring or surface functionalization. Unlike typical crystalline layered materials, graphene oxide (GO) possesses reactive oxygenated functional groups, which lead to spontaneous reduction and stacking upon thermal treatment. Here, we investigated the functionalization of GO with different amounts of hexylamine to control the degree of surface coverage. Furthermore, octylamine and dodecylamine were employed to confirm the effect of the alkyl chain length on the interlayer distance of the resultant GO derivatives. Subsequent thermal treatment produced reduced GO (rGO) functionalized with alkylamines, demonstrating the retention of the interlayer distance. Additionally, amine-functionalized rGOs exhibited varying porous structures.

kn-title=Structural basis for molecular assembly of fucoxanthin chlorophyll a/c-binding proteins in a diatom photosystem I supercomplex
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Photosynthetic organisms exhibit remarkable diversity in their light-harvesting complexes (LHCs). LHCs are associated with photosystem I (PSI), forming a PSI-LHCI supercomplex. The number of LHCI subunits, along with their protein sequences and pigment compositions, has been found to differ greatly among the PSI-LHCI structures. However, the mechanisms by which LHCIs recognize their specific binding sites within the PSI core remain unclear. In this study, we determined the cryo-electron microscopy structure of a PSI supercomplex incorporating fucoxanthin chlorophyll a/c-binding proteins (FCPs), designated as PSI-FCPI, isolated from the diatom Thalassiosira pseudonana CCMP1335. Structural analysis of PSI-FCPI revealed five FCPI subunits associated with a PSI monomer; these subunits were identified as RedCAP, Lhcr3, Lhcq10, Lhcf10, and Lhcq8. Through structural and sequence analyses, we identified specific protein?protein interactions at the interfaces between FCPI and PSI subunits, as well as among FCPI subunits themselves. Comparative structural analyses of PSI-FCPI supercomplexes, combined with phylogenetic analysis of FCPs from T. pseudonana and the diatom Chaetoceros gracilis, underscore the evolutionary conservation of protein motifs crucial for the selective binding of individual FCPI subunits. These findings provide significant insights into the molecular mechanisms underlying the assembly and selective binding of FCPIs in diatoms.

kn-title=Using a microfluidic paper-based analytical device and solid-phase extraction to determine phosphate concentration
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Phosphate is an essential nutrient, but in high concentrations it contributes to water pollution. Traditional methods for phosphate measurement, such as absorption spectrophotometry and ion chromatography, require expensive equipment and skilled operators. This study introduces a microfluidic paper-based analytical device (μPAD) that is designed to accomplish field-based, low-concentration phosphate measurements. This μPAD utilizes colorimetric detection based on the molybdenum blue method. Herein, we describe how the conditions were optimized in terms of design and sensitivity by adjusting reagent concentrations, paper thickness, and the time frames for sample introduction, and reaction. The operation consists of simply dipping the μPAD into a sample, capturing images in a home-made photo studio box, and processing the images with ImageJ software to measure RGB intensity. An additional preconcentration step involves solid-phase extraction with an anion exchange resin that achieves a 10-fold enrichment, which enables detection that ranges from 0.05 to 1 mg L?1 with a detection limit of 0.089 mg L?1 and a quantification limit of 0.269 mg L?1. The replicated measurements showed good reproducibility both intraday and interday (five different days) as 4.7 % and 3.0 % of relative standard deviations, respectively. After storage in a refrigerator for as long as 26 days, this μPAD delivered stable and accurate results for real-world samples of natural water, soil, and toothpaste. The results produced using this system correlate well with those produced via spectrophotometry. This μPAD-based method is a cost-effective, portable, rapid, and simple approach that allows relatively unskilled operators to monitor phosphate concentrations in field applications.

kn-title=Structure of a photosystem I supercomplex from Galdieria sulphuraria close to an ancestral red alga
en-subtitle=

en-abstract=
kn-abstract=Red algae exhibit unique photosynthetic adaptations, characterized by photosystem I (PSI) supercomplexes containing light-harvesting complexes (LHCs), forming PSI-LHCI supercomplexes. In this study, we solved the PSI-LHCI structure of Galdieria sulphuraria NIES-3638 at 2.19-angstrom resolution using cryo-electron microscopy, revealing a PSI monomer core associated with seven LHCI subunits. Structural analysis uncovered the absence of phylloquinones, the common secondary electron acceptor in PSI of photosynthetic organisms, suggesting adaptation to a benzoquinone-like molecule. Phylogenetic analysis suggests that G. sulphuraria retains traits characteristic of an ancestral red alga, including distinctive LHCI binding and interaction patterns. Variations in LHCI composition and interactions across red algae, particularly in red-lineage chlorophyll a/b-binding-like protein and red algal LHCs, highlight evolutionary divergence and specialization. These findings not only deepen our understanding of red algal PSI-LHCI diversification but also enable us to predict features of an ancestral red algal PSI-LHCI supercomplex, providing a framework to explore evolutionary adaptations from an ancestral red alga.

kn-title=Structure of a photosystem II-FCPII supercomplex from a haptophyte reveals a distinct antenna organization
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Haptophytes are unicellular algae that produce 30 to 50% of biomass in oceans. Among haptophytes, a subset named coccolithophores is characterized by calcified scales. Despite the importance of coccolithophores in global carbon fixation and CaCO3 production, their energy conversion system is still poorly known. Here we report a cryo-electron microscopic structure of photosystem II (PSII)-fucoxanthin chlorophyll c-binding protein (FCPII) supercomplex from Chyrostila roscoffensis, a representative of coccolithophores. This complex has two sets of six dimeric and monomeric FCPIIs, with distinct orientations. Interfaces of both FCPII/FCPII and FCPII/core differ from previously reported. We also determine the sequence of Psb36, a subunit previously found in diatoms and red algae. The principal excitation energy transfer (EET) pathways involve mainly 5 FCPIIs, where one FCPII monomer mediates EET to CP47. Our findings provide a solid structural basis for EET and energy dissipation pathways occurring in coccolithophores.

kn-title=Electrochemical Oxidation of Benzyl Alcohols via Hydrogen Atom Transfer Mediated by 2,2,2-Trifluoroethanol
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We report a novel electrochemical oxidation of benzyl alcohols. We found that trifluoroethanol plays a role as a hydrogen atom transfer (HAT) mediator, enabling the oxidation of electron-deficient substrates that are difficult to directly oxidize on electrode surfaces. Density functional theory calculations, cyclic voltammetry measurements, and constant potential electrolysis studies supported the proposed HAT mechanism. Moreover, the obtained carbonyl compounds could be functionalized in an electrochemical one-pot manner, further highlighting their synthetic utility.

kn-title=南西諸島の前弧域における付加体を含む堆積層のモデル化
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=　We combine the recent seismic reflection profiles to construct a new seismic velocity model of the sedimentary layer incorporating the accretionary prism along the Ryukyu trench. In constructing the new model, we refer to the zoning (ZONE1 to ZONE4) identified by Okamura et al. (2017, Tectonophys.). The construction process consists of the following steps: First, we digitize either unconformities or VP=4 to 5 km/s lines as the seismic basement, whichever is more clearly identifiable. Second, the digitized thickness data of the sedimentary layer from the reflection profiles are geometrically modeled and interpolated to make the three-dimensional structure model. Finally, we supplement the external region of the constructed 3-D sedimentary model using the J-SHIS model provided by the NIED to complete the velocity structure model in the entire Ryukyu arc. The main features of our model are as follows: In ZONE1, off Ishigaki-jima island, the thick sedimentary layer extends about 50 km wide from the Ryukyu trench. In ZONE2, off Miyako-jima island, the thinner layer compared to the other zones is found near the trench, with a thin sedimentary terrace covering the area behind it. In ZONE3, off Okinawa-jima island, the sedimentary layer deepens as it approaches the trench. In ZONE4, off Tokara islands, the deepest layer among all zones is identified. We then conduct 3-D finite-difference simulations of seismic wave propagation using the new and the previous models to confirm the improvement of the new model. In the simulations, the effects of the accretionary prism along the Ryukyu trench on the seismic wave propagation are clearly identified.

kn-title=An Implementation of Creep Test Assisting System with Dial Gauge Needle Reading and Smart Lighting Function for Laboratory Automation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=For decades, analog dial gauges have been essential for measuring and monitoring data at various industrial instruments including production machines and laboratory equipment. Among them, we focus on the instrument for creep test in a mechanical engineering laboratory, which evaluates material strength under sustained stress. Manual reading of gauges imposes significant labor demands, especially in long-duration tests. This burden further increases under low-lighting environments, where poor visibility can lead to misreading data points, potentially compromising the accuracy of test results. In this paper, to address the challenges, we implement a creep test assisting system that possesses the following features: (1) to save the installation cost, a web camera and Raspberry Pi are employed to capture images of the dial gauge and automate the needle reading by image processing in real time, (2) to ensure reliability under low-lighting environments, a smart lighting mechanism is integrated to turn on a supplementary light when the dial gauge is not clearly visible, and (3) to allow a user to stay in a distant place from the instrument during a creep test, material break is detected and the corresponding message is notified to a laboratory staff using LINE automatically. For evaluations, we install the implemented system into a material strength measuring instrument at Okayama University, Japan, and confirm the effectiveness and accuracy through conducting experiments under various lighting conditions.

kn-title=Spray-drying of polymer solutions across a broad concentration range and the subsequent formation of a few micro- ?nano-meter sized fibers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Spray drying is a widely utilized technique for the concentration and fine particulation of dried products. This study demonstrated that a versatile spray dryer, equipped with a two-fluid nozzle atomizer, can convert polymer solutions into nanoscale fibers by manipulating the conditions of the polymer solutions. The polymers employed in this research included polyvinylpyrrolidones (Mw 24.5 k to 60?kDa), dextrans (70 k to 450?650?kDa), pullulan, gum Arabic, Eudragit and agar, with methanol and water serving as solvents. Various combinations of polymers and solvents were subjected to spray drying at polymer concentrations ranging from 5 to 1000?g/L. Scanning electron microscopy analyses of the spray-dried samples indicated that the products transitioned from micrometer-sized particles to sub-micrometer fibers in several instances when the polymer concentrations exceeded specific threshold levels. The investigation also explored the relationship between these threshold concentrations and the surface tension and viscosity of the polymer solutions.

kn-title=Length Estimation of Pneumatic Artificial Muscle with Optical Fiber Sensor Using Machine Learning
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A McKibben artificial muscle is a soft actuator driven by air pressure, characterized by its flexibility, lightweight design, and high power-to-weight ratio. We have developed a smart artificial muscle that is capable of sensing its motion. To enable this sensing function, an optical fiber was integrated into the sleeve consisting of multiple fibers and serving as a component of the McKibben artificial muscle. By measuring the macrobending loss of the optical fiber, the length of the smart artificial muscle is expected to be estimated. However, experimental results indicated that the sensor's characteristics depend not only on the length but also on the load and the applied air pressure. This dependency arises because the stress applied to the optical fiber increases, causing microbending loss. In this study, we employed a machine learning model, primarily composed of Long Short-Term Memory (LSTM) neural networks, to estimate the length of the smart artificial muscle. The experimental results demonstrate that the length estimation obtained through machine learning exhibits a smaller error. This suggests that machine learning is a feasible approach to enhancing the length measurement accuracy of the smart artificial muscle.

kn-abstract=The densities of liquid materials at high pressures and high temperatures are important information to understand the elastic behavior of liquids at extreme conditions, which is closely related to the formation and evolution processes of the Earth and planetary interiors. The x-ray absorption method is an effective method to measure the density of non-crystalline materials at high pressures. However, the temperature condition of the x-ray absorption method using a diamond anvil cell (DAC) has been limited to 720 K to date. To significantly expand the measurable temperature condition of this method, in this study, we developed a density measurement technique using the x-ray absorption method in combination with a laser-heated DAC. The density of solid Ni was measured up to 26 GPa and 1800 K using the x-ray absorption method and evaluated by comparison with the density obtained from the x-ray diffraction. The density of solid Ni with a thickness >17 μm was determined with an accuracy of 0.01%?2.2% (0.001?0.20 g/cm3) and a precision of 0.8%?1.8% (0.07?0.16 g/cm3) in the x-ray absorption method. The density of liquid Ni was also determined to be 8.70 ± 0.15?8.98 ± 0.38 g/cm3 at 16?23 GPa and 2230?2480 K. Consequently, the temperature limit of the x-ray absorption method can be expanded from 720 to 2480 K by combining it with a laser-heated DAC in this study.

kn-title=Facial Privacy Protection with Dynamic Multi-User Access Control for Online Photo Platforms
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In the digital age, sharing moments through photos has become a daily habit. However, every face captured in these photos is vulnerable to unauthorized identification and potential misuse through AI-powered synthetic content generation. Previously, we introduced SnapSafe, a secure system for enabling selective image privacy focusing on facial regions for single-party scenarios. Recognizing that group photos with multiple subjects are a more common scenario, we extend SnapSafe to support multi-user facial privacy protection with dynamic access control designed for online photo platforms. Our approach introduces key splitting for access control, an owner-centric permission system for granting and revoking access to facial regions, and a request-based mechanism allowing subjects to initiate access permissions. These features ensure that facial regions remain protected while maintaining the visibility of non-facial content for general viewing. To ensure reproducibility and isolation, we implemented our solution using Docker containers. Our experimental assessment covered diverse scenarios, categorized as "Single", "Small", "Medium", and "Large", based on the number of faces in the photos. The results demonstrate the system's effectiveness across all test scenarios, consistently performing face encryption operations in under 350 ms and achieving average face decryption times below 286 ms across various group sizes. The key-splitting operations maintained a 100% success rate across all group configurations, while revocation operations were executed efficiently with server processing times remaining under 16 ms. These results validate the system's capability in managing facial privacy while maintaining practical usability in online photo sharing contexts.

en-subtitle=

en-abstract=
kn-abstract=[n]Phenacenes ([n] = 5-7), octafluorinated at the terminal benzene rings (F8-phenacenes: F8PIC, F8FUL, and F87PHEN), were photochemically synthesized, and their electronic spectra were investigated to reveal the effects of the fluorination on the electronic features of phenacene molecules. F8-Phenacenes were conveniently synthesized by the Mallory photoreaction of the corresponding fluorinated diarylethenes as the key step. Upon fluorination on the phenacene cores, the absorption and fluorescence bands of the F8-phenacenes in CHCl3 systematically red-shifted by ca. 3-5 nm compared to those of the corresponding parent phenacenes. The vibrational progressions of the absorption and fluorescence bands were little affected by the fluorination in the solution phase. In the solid state, the absorption band of F8-phenacenes appeared in the similar wavelength region for the corresponding parent phenacenes whereas their fluorescence bands markedly red-shifted and broadened. These observations suggest that the intermolecular interactions of excited-state F8-phenacene molecules are significantly different from those of the corresponding parent molecules, most likely due to different crystalline packing motifs.

kn-title=Local-structure insight into the improved superconducting properties of Pb-substituted La(O, F)BiS2: a photoelectron holography study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Pb-substituted La(O, F)BiS2 (Pb-LaOFBiS2) exhibits improved superconducting properties and a resistivity anomaly around 100 K that is attributed to a structural transition. We have performed temperature(T)-dependent photoelectron holography (PEH) to study dopant incorporation sites and the local structure change across the anomaly. The PEH study of Pb-LaOFBiS2 provided evidence for the dominant incorporation sites of Pb and F: Pb atoms are incorporated into the Bi sites and F atoms are incorporated into the O site. No remarkable difference in the local structures around Pb and Bi atoms was observed. Across the temperature of the resistivity anomaly (T*), photoelectron holograms of Bi 4f changed. Comparisons of holograms with those of non-substituted LaOFBiS2 sample, as well as simulated holograms, suggested that (1), above T*, the tetragonal structure of Pb-LaOFBiS2 is different from the tetragonal structure of LaOFBiS2 and (2), below T*, the tetragonal structure still remains in Pb-LaOFBiS2. We discuss a possible origin of the difference in the structure above T* and the implication of the result below T*, which are necessary ingredients to understand the physical properties of Pb-LaOFBiS2.

kn-title=Specific enhancement of the translation of thermospermine-responsive uORF-containing mRNAs by ribosomal mutations in Arabidopsis thaliana
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Auxin-induced xylem formation in angiosperms is negatively regulated by thermospermine, whose biosynthesis is also induced by auxin. In Arabidopsis thaliana, loss-of-function mutants of ACL5, which encodes thermospermine synthase, exhibit a dwarf phenotype accompanied by excessive xylem formation. Studies of suppressor mutants that recover from the acl5 dwarf phenotype suggest that thermospermine alleviates the inhibitory effect of an upstream open-reading frame (uORF) on the main ORF translation of SAC51 mRNA. Many suppressor mutations for acl5 have been mapped to the uORF conserved in the SAC51 family or to ribosomal protein genes, such as RPL10A, RPL4A, and RACK1A. In this study, we identified newly isolated acl5 suppressors, sac501, sac504, and sac506, which are additional alleles of RPL10A and the uORFs of SAC51 family members, SACL1 and SACL3, respectively. To investigate whether acl5-suppressor alleles of ribosomal genes broadly affect translation of uORF-containing mRNAs, we examined GUS activity in several 5'-GUS fusion constructs. Our results showed that these alleles enhanced GUS activity in SAC51 and SACL3 5'-fusion constructs but had no effect on other 5'-fusion constructs unrelated to thermospermine response. This suggests that these ribosomal proteins are specifically involved in the thermospermine-mediated regulation of mRNA translation.

kn-title=Droplet Impact Behavior on Convex Surfaces with a Circumferential Wettability Difference
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Controlling the bouncing behavior of the impacting droplets is an important issue for splay cooling, icing prevention, and other applications. The bouncing behavior of impacting droplets on superhydrophobic curved surfaces and flat substrates with a wettability difference has been widely investigated, and droplets impacting these surfaces show shorter contact times than those on superhydrophobic flat surfaces and droplet transport. However, there have been few studies on the droplet impact behavior on curved surfaces with a wettability difference, where efficient droplet control could be achieved by combining the features. In the present study, droplet impact experiments were conducted using copper cylinders with different circumferential wettabilities from hydrophilic to superhydrophobic, varying the impact velocity, cylinder diameter, and rotation angle. Droplets that impacted the wettability boundary showed asymmetric deformation and moved to the hydrophilic side, owing to the driving force of the wettability difference. Moreover, the droplet behavior was classified into four types: the droplet bounced off the surface, the droplet bounced off the surface and split, the droplet attached to the surface, and the droplet attached to the surface and split. The droplet behavior was estimated by using the maximum spreading width of the droplet impacted on the flat substrate. We evaluated whether the droplets attached to the surface or bounced off the surface after impact using the Weber number and rotation angle, and the estimations were in agreement with the experimental results for cylinder diameters of 4 and 6 mm.

kn-title=Keratinocyte-driven dermal collagen formation in the axolotl skin
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Type I collagen is a major component of the dermis and is formed by dermal fibroblasts. The development of dermal collagen structures has not been fully elucidated despite the major presence and importance of the dermis. This lack of understanding is due in part to the opacity of mammalian skin and it has been an obstacle to cosmetic and medical developments. We reveal the process of dermal collagen formation using the highly transparent skin of the axolotl and fluorescent collagen probes. We clarify that epidermal cells, not dermal fibroblasts, contribute to dermal collagen formation. Mesenchymal cells (fibroblasts) play a role in modifying the collagen fibers already built by keratinocytes. We confirm that collagen production by keratinocytes is a widely conserved mechanism in other model organisms. Our findings warrant a change in the current consensus about dermal collagen formation and could lead to innovations in cosmetology and skin medication.

kn-title=A microfluidic paper-based analytical device that uses gelatin film to assay protease activity via time readout
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Food processing, detergents, and pharmaceuticals frequently employ proteases, which are enzymes that break the chemical bonds of both proteins and peptides. In this work, we developed a microfluidic paper-based analytical device (?PAD) for protease activity assays via time readout. To accomplish this, we folded the ?PAD to form layers, then inserted a water-insoluble gelatin film between the layers of paper to form the device. Lamination helps to maintain the gelatin film between the introduction zone, which is the upper layer, and the detection channel, which is the lower layer. Proteases decompose the gelatin film when it enters the introduction zone, which then allows it to flow into the detection channel. The protease activity in the sample solution determines the time required to dissolve the gelatin film, which leads to a linear relationship between the logarithm of the protease concentration and the time required to flow the solution a specific distance on the detection channel. The ?PAD was used to measure proteases in concentrations that ranged from 0.25 to 1 mg L?1 for bromelain, 2.5 to 10 mg L?1 for papain, and 1 to 8 mg L?1 for trypsin. The limits of quantification for bromelain, papain, and trypsin were 0.41, 2.7, and 9.2 mg mL?1, respectively. The relative standard deviations for bromelain were smaller than 2 % for concentrations ranging from 0.5 to 1.0 mg L?1. We compared the ?PAD to a commercially available protease activity assay kit, which relies on quenching fluorescein isothiocyanate-labeled casein. Both methods demonstrated the same order of activity: bromelain > papain > trypsin. The proposed device allowed the assay of bromelain in both pineapple pulp and juice, which were stored at room temperature. When first using the proposed device, the bromelain in the pulp gradually lost its activity, while the activity of the bromelain in the juice showed no significant change for five days. The ?PAD requires no analytical instruments for quality control and monitoring of the protease activity in food.

kn-title=Recent development of azahelicenes showing circularly polarized luminescence
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Recently, a variety of circularly polarized luminescence (CPL) dyes have been developed as next-generation chiroptical materials. Helicenes, ortho-fused aromatics, have been recognized as some of the most promising CPL dyes. Although typical carbohelicenes show CPL, weak fluorescence is often emitted in the blue region. In contrast, heteroatom-embedded helicenes (heterohelicenes) can show intense fluorescence and CPL in the visible region because heteroatoms alter the electronic states of helicene frameworks. Among various heterohelicenes, nitrogen-embedded helicenes (azahelicenes) have unique features such as facile functionalization and sensitive responses to acid/base or metal ions. Furthermore, polycyclic aromatic hydrocarbons (PAHs) containing azaborine units have been recognized as excellent luminescent materials, and the helical derivatives, B,N-embedded helicenes, have been rapidly growing recently. In this feature article, we review and summarize the synthesis and chiroptical properties of azahelicenes, which are classified into imine-type and amine-type azahelicenes and B,N-embedded helicenes. CPL switching systems of azahelicenes are also reviewed.

kn-title=Deep Reinforcement Learning for Dynamic Pricing and Ordering Policies in Perishable Inventory Management
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Perishable goods have a limited shelf life, and inventory should be discarded once it exceeds its shelf life. Finding optimal inventory management policies is essential since inefficient policies can lead to increased waste and higher costs. While many previous studies assume the perishable inventory is processed following the First In, First Out rule, it does not reflect customer purchasing behavior. In practice, customers' preferences are influenced by the shelf life and price of products. This study optimizes inventory and pricing policies for a perishable inventory management problem considering age-dependent probabilistic demand. However, introducing dynamic pricing significantly increases the complexity of the problem. To tackle this challenge, we propose eliminating irrational actions in dynamic programming without sacrificing optimality. To solve this problem more efficiently, we also implement a deep reinforcement learning algorithm, proximal policy optimization, to solve this problem. The results show that dynamic programming with action reduction achieved an average of 63.1% reduction in computation time compared to vanilla dynamic programming. In most cases, proximal policy optimization achieved an optimality gap of less than 10%. Sensitivity analysis of the demand model revealed a negative correlation between customer sensitivity to shelf lives or prices and total profits.

en-abstract=
kn-abstract=This paper studies polyhedral entire solutions to a bistable reaction-diffusion equation in Rn. We consider a pyramidal traveling front solution to the same equation in Rn+1. As the speed goes to infinity, its projection converges to an n-dimensional polyhedral entire solution. Conversely, as the time goes to -infinity, an n-dimensional polyhedral entire solution gives n-dimensional pyramidal traveling front solutions. The result in this paper suggests a correlation between traveling front solutions and entire solutions in general reaction-diffusion equations or systems.

kn-title=Microfluidic fabrication of rattle shaped biopolymer microcapsules via sequential phase separation in oil droplets
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Multilayer microcapsules containing a small particle within a larger capsule have recently attracted considerable attention owing to their potential applications in diverse fields, including drug delivery, active ingredient storage, and chemical reactions. These complex capsules have been fabricated using interfacial polymerization or seeded emulsion polymerization. However, these methods often require complex and lengthy polymerization processes, limiting their utility, particularly in biopolymer systems. This study introduces a simple and efficient approach for preparing rattle-shaped cellulose acetate (CA) microcapsules through sequential phase separation in droplets. We systematically examine the effects of various preparation parameters, including the amount of co-solvent, initial droplet size, and flow rates, and reveal that the incorporation of a co-solvent-ethyl acetate (EA)- in the dispersed phase significantly impacts the microcapsule morphology. Our findings demonstrate a transition from a core-shell to a rattle-shaped structure as the EA concentration increases. Furthermore, the initial droplet diameter and flow rates influence microcapsule formation-larger droplets and reduced continuous-phase flow rates favor the development of multi-layered structures. These results indicate that the formation mechanism of these rattle-shaped microcapsules arises from the establishment of a radial solvent concentration gradient and subsequent phase separation within the droplets, driven by kinetic rather than thermodynamic factors.

kn-title=Antifouling Activity of Xylemin, Its Structural Analogs, and Related Polyamines
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Biofouling, which is the accumulation of organisms on undersea structures, poses significant global, social, and economic issues. Although organotin compounds were effective antifoulants since the 1960s, they were banned in 2008 due to their toxicity to marine life. Although tin-free alternatives have been developed, they also raise environmental concerns. This underscores the need for effective, nontoxic antifouling agents. We previously synthesized N-(4-aminobutyl)propylamine (xylemin) and its structural analogs. In this study, we assayed the antifouling activity and toxicity of xylemin, its structural analogs, and related polyamines toward cypris larvae of the barnacle Amphibalanus amphitrite. Xylemin and its Boc-protected analog exhibited antifouling activities with 50% effective concentrations (EC50) of 4.25 and 6.11 ?g/mL, respectively. Four xylemin analogs did not show a settlement-inhibitory effect at a concentration of 50 ?g/mL. Putrescine, spermidine, spermine, and thermospermine, which are xylemin-related polyamines, did not display antifoulant effects (EC50 > 50 ?g/mL). All evaluated compounds were nontoxic at a concentration of 50 ?g/mL. These findings indicate that the size and structure of the N-alkyl group are essential for the antifouling activity of xylemin. Therefore, xylemin and its analogs hold promise as nontoxic, eco-friendly antifouling agents, offering a sustainable solution to biofouling in marine environments.

kn-abstract=Intramolecular oxidative aromatic coupling of 3,6-bis(m-terphenyl-2’-yl)carbazole provided a bis(m-terphenyl)-fused carbazole, while that of 3,6-bis(m-terphenyl-2’-yl)-1,8-diphenylcarbazole afforded a bis(quaterphenyl)-fused carbazole. Borylation of the latter furnished a B,N-embedded helical nanographene binding a fluoride anion via a structural change from the three-coordinate boron to the four-coordinate boron. The anionic charge derived from the fluoride anion is stabilized over the expanded π-framework, which leads to the high binding constant (Ka) of 1×105?M?1. The four-coordinate boron species was converted back to the parent three-coordinate boron species with Ag+, and the chiroptical switch between the three-coordinate boron and four-coordinate boron species has been achieved via the ion recognition with the change in the color and glum values.

For each slip system of the grain, we calculated the slip factor, defined as the ratio of resolved shear stresses that considers the singular stress field at the crack tip, and investigated the relationship between the propagation behavior of small cracks and the slip factor. Furthermore, we performed a crystal plasticity finite element analysis (CP-FEM) using a crystal plasticity FEM model created from the grains obtained by the EBSD method to predict the deflection behavior of small fatigue cracks when propagating through the grain boundaries. The results indicated that when a crack propagates across a grain boundary, it is difficult to predict the deflection behavior using slip factors, however, the deflection behavior of a crack can be predicted from the resolved shear stress calculated using CP-FEM, which considers the mechanical interactions between crystal grains.

kn-title=Structural basis for molecular assembly of fucoxanthin chlorophyll a/c-binding proteins in a diatom photosystem I supercomplex
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Photosynthetic organisms exhibit remarkable diversity in their light-harvesting complexes (LHCs). LHCs are associated with photosystem I (PSI), forming a PSI-LHCI supercomplex. The number of LHCI subunits, along with their protein sequences and pigment compositions, has been found to differ greatly among the PSI-LHCI structures. However, the mechanisms by which LHCIs recognize their specific binding sites within the PSI core remain unclear. In this study, we determined the cryo-electron microscopy structure of a PSI supercomplex incorporating fucoxanthin chlorophyll a/c-binding proteins (FCPs), designated as PSI-FCPI, isolated from the diatom Thalassiosira pseudonana CCMP1335. Structural analysis of PSI-FCPI revealed five FCPI subunits associated with a PSI monomer; these subunits were identified as RedCAP, Lhcr3, Lhcq10, Lhcf10, and Lhcq8. Through structural and sequence analyses, we identified specific protein-protein interactions at the interfaces between FCPI and PSI subunits, as well as among FCPI subunits themselves. Comparative structural analyses of PSI-FCPI supercomplexes, combined with phylogenetic analysis of FCPs from T. pseudonana and the diatom Chaetoceros gracilis, underscore the evolutionary conservation of protein motifs crucial for the selective binding of individual FCPI subunits. These findings provide significant insights into the molecular mechanisms underlying the assembly and selective binding of FCPIs in diatoms.

en-abstract=　世界において，乳牛の受胎率（妊娠率）が低下しており，家畜の繁殖成績向上のための効果的な治療法が必要とされている．家畜を含む哺乳類において，生殖機能は視床下部−下垂体−性腺軸から分泌されるホルモンによって制御されている．これらのホルモンのうち，性腺刺激ホルモン放出ホルモン（GnRH）のパルス状分泌（GnRH パルス）は，性腺刺激ホルモン分泌と性腺機能に本質的に重要である．したがって，GnRH パルスを制御するメカニズム（GnRH パルスジェネレーター）を解明することは，家畜の生殖技術を向上させるために不可欠である．本総説では，著者らの遺伝子改変ラットモデルを用いた弓状核キスペプチンニューロン（ΚNDy ニューロンとしても知られる）がGnRH パルスジェネレーターの本体であることの直接的な証拠を示した研究を中心として，過去20年間の研究を概説した．また，ΚNDy ニューロンが分泌するニューロキニンB，グルタミン酸，ダイノルフィンA がΚNDy ニューロンの神経活動を同期させ，GnRH パルスを発生させるメカニズムについて論じた．遺伝子改変ラットモデルから得られた知識は，GnRH/ 性腺刺激ホルモンパルスを刺激して，家畜の繁殖能力を向上させる新規繁殖促進剤開発に寄与すると期待できる．
kn-abstract=　Strategies for increasing reproductive performance are needed for domestic animals because for example the conception (pregnancy) rate has decreased in dairy cows around the world. Reproductive function is controlled by hormones released by the hypothalamus-pituitary-gonadal axis in mammals, including domestic animals. Of those hormones, tonic (pulsatile) gonadotropin-releasing hormone (GnRH) release is fundamentally important for gonadotropin release and gonadal activity. Therefore, uncovering the mechanism controlling GnRH pulses, that is GnRH pulse generator, is essential to improve reproductive technologies for domestic animals. The present review is focused on the indispensable role of arcuate nucleus (ARC) kisspeptin neurons (also known as KNDy neurons) as the GnRH pulse generator in mammals. First, we give a brief overview of studies on hypothalamic kisspeptin neurons throughout the past two decades. Second, we review studies that have provided direct evidence that ARC kisspeptin neurons serve as the GnRH pulse generator, with a special focus on our gene-modified rat models. Finally, we discuss the mechanism underlying GnRH pulse generation. The knowledge obtained from gene-modified rat models should be clinically important and could be adapted to new tools to improve reproductive performance in livestock by stimulating GnRH/gonadotropin pulses.

kn-title=The Impact of Task Context on Pleasantness and Softness Estimations: A Study Based on Three Touch Strategies
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study investigated the two distinct perceptions (pleasantness and softness) of deformable stimuli with different degrees of compliance under conditions with and without a contextual task. Three tactile strategies-grasping, pinching, and pressing-were used to perceive the stimuli. In Experiment 1 (without a contextual task), participants estimated the perceived intensity of softness or pleasantness for each stimulus. In Experiment 2 (with a contextual task), the participants sequentially perceived two stimuli with different compliance levels and indicated which stimulus they perceived as softer and pleasant. The results showed that the psychophysical relationship between compliance and perceived softness was consistent across all tactile strategies in both experiments, with softness estimates increasing as compliance increased. However, the relationship between compliance and pleasantness differed between the two experiments. In Experiment 1, pleasantness estimates increased monotonically with increased compliance. However, in Experiment 2, across all tactile strategies, pleasantness began to decrease within the compliance range of 0.25-2.0 cm2/N, exhibiting an inverted U-shaped trend. These findings indicate that the relationship between compliance and pleasantness is task-dependent, particularly demonstrating significantly different trends when a contextual task is introduced. In contrast, the relationship between compliance and softness remained consistently monotonic.

kn-title=Modification on Thermal Motion in Geant4 for Neutron Capture Simulation in Gadolinium Loaded Water
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Neutron tagging is a fundamental technique for electron anti-neutrino detection via the inverse beta decay channel. A reported discrepancy in neutron detection efficiency between observational data and simulation predictions prompted an investigation into neutron capture modeling in Geant4. The study revealed that an overestimation of the thermal motion of hydrogen atoms in Geant4 impacts the fraction of captured nuclei. By manually modifying the Geant4 implementation, the simulation results align with calculations based on evaluated nuclear data and show good agreement with observables derived from the SK-Gd data.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Detecting low concentrations of viruses in sewage water is crucial for monitoring the spread of emerging viral diseases. However, current detection methods, which involve concentrating viruses using traditional materials such as gauze or cotton, have limitations in effectively accomplishing this task. This study demonstrates that graphene oxide (GO), a two-dimensional carbon material, possesses strong viral adsorption capabilities. However, it lacks efficiency for effective viral release. Therefore, we designed a series of new GO-based materials, which exhibited a viral adsorption similar to pristine GO, while significantly enhancing their release performance by attaching alkyl chains and hydrophilic functional groups. Among the synthesized materials, 1,8-aminooctanol grafted to GO (GO-NH2C8OH) has emerged as the most promising candidate, achieving a viral release rate higher than 50 %. This superior performance can be attributed to the synergistic effect of the alkyl chain and the terminal OH group, which enhances both its affinity for viruses and water dispersibility. Furthermore, we have successfully applied GO-NH2C8OH in a new protocol for concentrating viruses from sewage wastewater. This approach has demonstrated a 200-fold increase in virus concentration, allowing PCR detection of this type of pathogens present in wastewater below the detection limit by direct analysis, underscoring its significant potential for virus surveillance.

en-subtitle=

en-abstract=
kn-abstract=Multidimensional traveling front solutions and entire solutions of reaction-diffusion equations have been studied intensively. To study the relationship between multidimensional traveling front solutions and entire solutions, we study the reaction-diffusion equation with a bistable nonlinear term. It is well known that there exist multidimensional traveling front solutions with every speed that is greater than the speed of a one-dimensional traveling front solution connecting two stable equilibria. In this paper, we show that the limit of the n-dimensional multidimensional traveling front solutions as the speeds go to infinity generates an entire solution of the same reaction-diffusion equation in the (n-1)-dimensional space.

en-abstract=
kn-abstract=This study presents a novel nanostructured material formed by inserting oxidized carbon nanohorns (CNHox) between layered graphene oxide (GO) nanosheets using metal ions (M) from nitrate as intermediates. The resulting GO?CNHox-M structure effectively mitigated interlayer aggregation of the GO nanosheets. This insertion strategy promoted the formation of nanowindows on the surface of the GO sheets and larger mesopores between the GO nanosheets, improving material porosity. Characterization revealed successful CNHox insertion, which increased interlayer spacing and reduced GO stacking. The GO?CNHox-Ca exhibited a significantly higher specific surface area (SSA) and pore volume than pure GO, with values of 374 m2 g?1 and 0.36 mL g?1, respectively. The GO?CNHox-K composite also exhibited a well-developed pore structure with an SSA of 271 m2 g?1 and pore volume of 0.26 mL g?1. These findings demonstrate that Ca2+ or K+ ions effectively link GO and CNHox, validating the success of this insertion approach in reducing GO aggregation. Metal ions played a crucial role in the insertion process by facilitating electrostatic interactions and coordination bonds between GO and CNHox. This study provides new insights into reducing GO agglomeration and expanding the application of GO-based materials.

kn-title=Crosstalk between prolactin, insulin-like growth factors, and thyroid hormones in feather growth regulation in neonatal chick wings
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The elongation of primary feathers in neonatal chicks is delayed by the late-feathering K gene located on the Z chromosome. We recently found that the K gene slows feather growth by reducing the number of functional prolactin (PRL) receptor (PRLR) dimers. In this study, we investigated the molecular mechanisms by which PRL promotes feather elongation. RT-qPCR and immunohistochemistry analyses revealed that PRLRs are predominantly localized in the pulp rather than in the epidermal layer of the feather follicle. Treatment of primary cultured feather pulp cells with PRL increased the expression of mRNAs for insulin-like growth factors (IGFs; IGF-1 and IGF-2) and type 2 deiodinase (DIO2). Furthermore, treatments with IGF-1 and triiodothyronine (T3) reciprocally enhanced the expression of mRNAs for DIO2 and IGFs. Additionally, BrdU staining in neonatal chicks showed that T3 promoted cell proliferation in both the epidermal layer and pulp cells, while this effect was suppressed by an IGF-1 receptor (IGF1R) inhibitor. These findings suggest a novel model in which PRL upregulates IGFs and DIO2 in feather pulp cells, creating a positive feedback loop between IGFs and T3, ultimately leading to the promotion of cell proliferation in both the epidermal layer and the pulp cells by IGFs. This is the first report proposing crosstalk between PRL, thyroid hormone (TH), and IGFs in feather follicles.

kn-title=Identification of pennaceous barbule cell factor (PBCF), a novel gene with spatiotemporal expression in barbule cells during feather development
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Bird contour feathers exhibit a complex hierarchical structure composed of a rachis, barbs, and barbules, with barbules playing a crucial role in maintaining feather structure and function. Understanding the molecular mechanisms underlying barbule formation is essential for advancing our knowledge of avian biology and evolution. In this study, we identified a novel gene, pennaceous barbule cell factor (PBCF), using microarray analysis, RT-PCR, and in situ hybridization. PBCF is expressed in barbule cells adjacent to the ramus during pennaceous barbule formation, where these cells fuse with the ramus to establish the feather’s branching structure. PBCF expression occurs transiently after melanin pigmentation of the barbule plates but before the expression of barbule-specific keratin 1 (BlSK1). Orthologues of PBCF, predicted to be secreted proteins, are conserved across avian species, with potential homologues detected in reptiles, suggesting an evolutionary lineage-specific adaptation. Additionally, PBCF is expressed in non-vacuolated notochord cells and the extra-embryonic ectoderm of the yolk sac, hinting at its broader developmental significance. The PBCF gene produces two mRNA isoforms via alternative splicing, encoding a secreted protein and a glycophosphatidylinositol (GPI)-anchored membrane-bound protein, indicating functional versatility. These findings suggest that PBCF may be involved as an avian-specific extracellular matrix component in cell adhesion and/or communication, potentially contributing to both feather development and embryogenesis. Further investigation of PBCF’s role in feather evolution and its potential functions in other vertebrates could provide new insights into the interplay between development and evolution.

kn-title=Novel Drug Delivery Particles Can Provide Dual Effects on Cancer "Theranostics" in Boron Neutron Capture Therapy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Boron (B) neutron capture therapy (BNCT) is a novel non-invasive targeted cancer therapy based on the nuclear capture reaction 10B (n, alpha) 7Li that enables the death of cancer cells without damaging neighboring normal cells. However, the development of clinically approved boron drugs remains challenging. We have previously reported on self-forming nanoparticles for drug delivery consisting of a biodegradable polymer, namely, “AB-type” Lactosome? nanoparticles (AB-Lac particles)- highly loaded with hydrophobic B compounds, namely o-Carborane (Carb) or 1,2-dihexyl-o-Carborane (diC6-Carb), and the latter (diC6-Carb) especially showed the “molecular glue” effect. Here we present in vivo and ex vivo studies with human pancreatic cancer (AsPC-1) cells to find therapeutically optimal formulas and the appropriate treatment conditions for these particles. The biodistribution of the particles was assessed by the tumor/normal tissue ratio (T/N) in terms of tumor/muscle (T/M) and tumor/blood (T/B) ratios using near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG). The in vivo and ex vivo accumulation of B delivered by the injected AB-Lac particles in tumor lesions reached a maximum by 12 h post-injection. Irradiation studies conducted both in vitro and in vivo showed that AB-Lac particles-loaded with either 10B-Carb or 10B-diC6-Carb significantly inhibited the growth of AsPC-1 cancer cells or strongly inhibited their growth, with the latter method being significantly more effective. Surprisingly, a similar in vitro and in vivo irradiation study showed that ICG-labeled AB-Lac particles alone, i.e., without any 10B compounds, also revealed a significant inhibition. Therefore, we expect that our ICG-labeled AB-Lac particles-loaded with 10B compound(s) may be a novel and promising candidate for providing not only NIRF imaging for a practical diagnosis but also the dual therapeutic effects of induced cancer cell death, i.e., “theranostics”.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=With the rapid advancement of information technology, there is a pressing need to develop ultracompact and energy-efficient thin-film-based electro-optic (EO) devices. A high EO coefficient in ferroelectric materials is crucial. However, substrate clamping can positively or negatively influence various physical properties, including the EO response of these films, thus complicating the development of next-generation thin-film-based devices. This study demonstrates that reversible dynamic domain motion, achieved through substrate clamping, significantly enhances the EO coefficient in epitaxial ferroelectric rhombohedral Pb(Zr, Ti)O3 thin films, where the (111) and (? 111?) domains coexist with distinct optical axes. In principle, this approach can be applied to different film-substrate systems, thereby contributing to the advancement of sophisticated EO devices based on ferroelectrics.

kn-title=Overloaded MIMO Spatial Multiplexing Independent of Antenna Setups
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This paper proposes overloaded MIMO spatial multiplexing that can increase the number of spatially multiplexed signal streams despite of the number of antennas on a terminal and that on a receiver. We propose extension of the channel matrix for the spatial multiplexing to achieve the superb multiplexing performance. Precoding based on the extended channel matrix plays a crucial role in carrying out such spatial multiplexing. We consider three types of QR-decomposition techniques for the proposed spatial multiplexing to improve the transmission performance. The transmission performance of the proposed spatial multiplexing is evaluated by computer simulation. The simulation reveals that the proposed overloaded MIMO spatial multiplexing can implement 6 stream-spatial multiplexing in a 2×2 MIMO system, i.e., the overloading ratio of 3.0. The superior transmission performance is achieved by the proposed overloaded MIMO spatial multiplexing with one of the QR-decomposition techniques.

kn-title=The Impact of Selective Spatial Attention on Auditory-Tactile Integration: An Event-Related Potential Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Auditory-tactile integration is an important research area in multisensory integration. Especially in special environments (e.g., traffic noise and complex work environments), auditory-tactile integration is crucial for human response and decision making. We investigated the influence of attention on the temporal course and spatial distribution of auditory-tactile integration. Methods: Participants received auditory stimuli alone, tactile stimuli alone, and simultaneous auditory and tactile stimuli, which were randomly presented on the left or right side. For each block, participants attended to all stimuli on the designated side and detected uncommon target stimuli while ignoring all stimuli on the other side. Event-related potentials (ERPs) were recorded via 64 scalp electrodes. Integration was quantified by comparing the response to the combined stimulus to the sum of the responses to the auditory and tactile stimuli presented separately. Results: The results demonstrated that compared to the unattended condition, integration occurred earlier and involved more brain regions in the attended condition when the stimulus was presented in the left hemispace. The unattended condition involved a more extensive range of brain regions and occurred earlier than the attended condition when the stimulus was presented in the right hemispace. Conclusions: Attention can modulate auditory-tactile integration and show systematic differences between the left and right hemispaces. These findings contribute to the understanding of the mechanisms of auditory-tactile information processing in the human brain.

kn-abstract=Accurate prediction of tool life is crucial for reducing production costs and enhancing quality in the machining process. However, such predictions often rely on empirical knowledge, which may limit inexperienced engineers to reliably obtain accurate predictions. This study explores a method to predict the tool life of a cutting machine using servo motor current data collected during the initial stages of tool wear, which is a cost-effective approach. The LightGBM model was identified as suitable for predicting tool life from current data, given the challenges associated with predicting from the average variation of current values. By identifying and utilizing the top 50 features from the current data for prediction, the accuracy of tool life prediction in the early wear stage improved. As this prediction method was developed based on current data obtained during the very early wear stage in experiments with square end-mills, it was tested on extrapolated data using different end-mill diameters. The findings revealed average accuracy rates of 71.2% and 69.4% when using maximum machining time and maximum removal volume as thresholds, respectively.

kn-title=Graphene Oxide as a Self‐Carbocatalyst to Facilitate the Ring‐Opening Polymerization of Glycidol for Efficient Polyglycerol Grafting
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Grafting carbon-based nanomaterials (CNMs) with polyglycerol (PG) improves their application potentials in biomedicine and electronics. Although “grafting from” method offers advantages over “grafting to” one in terms of operability and versatility, little is known about the reaction process of glycidol with the surface groups onto CNMs. By using graphene oxide (GO) as a multi-functional model material, we examined the reactivity of the surface groups on GO toward glycidol molecules via a set of model reactions. We reveal that carboxyl groups spontaneously react with the epoxide ring with no need of catalyst, while GO catalyzes the reactions of hydroxyl groups with the epoxide of glycidol. In addition, the hydroxyl group of glycidol can open the epoxide in the basal plane of GO. The subsequent polymerization of PG is supposed to propagate at the primary and/or the secondary hydroxyl groups, generating a ramified PG macromolecule with random branch-on-branch topology. In addition, ketones, benzyl esters and aromatic ethers are found not to react with glycidol even in the presence of GO, while the aldehydes are easily oxidized into carboxyl groups under ambient condition, behaving then as the carboxyl groups. Our findings pose the foundation for understanding the polymerization mechanism of PG on CNMs.

kn-abstract=We conducted mineralogical and geochemical analysis of ore samples taken from locations surrounding the Jinmu, Sanp?, and K?moto mines in order to determine the source of iron ore uncovered from archaeological sites. The mineral composition of the magnetite-garnet bearing skarn deposits varies from mine to mine: while clinopyroxene and amphibole are present in the Jinmu and Sanp? samples, only a small amount of clinopyroxene occurs in the K?moto samples. The chemical compositions of magnetite and garnet are distinctive for each mine. Among the trace elements contained in the magnetite, Mg and Mn tend to be higher in the K?moto samples, Ti in the Jinmu samples, and Ca and Si in the Sanp? samples. The garnet from all the mines is andradite, but while the K?moto samples contain almost no Al, it is present in the Jinmu and Sanp? samples. Although samples were taken from a limited number of mine areas (three), our analysis provides an index for comparison with iron ore uncovered from archaeological sites, which will aid in provenance determination.

However, previous studies have encountered challenges, such as the need for heating, a long reaction time, and/or the need for equivalent amounts of catalyst. In this study, we introduce an effective electrogenerated boron-based Lewis acid catalyst for the aromatic Claisen rearrangement, which proceeds in a few minutes at ambient temperature. Generation of the electrogenerated Lewis acid catalyst is discussed based on NMR analysis and DFT calculations.

kn-title=Mass Production of Graphene Oxide Beyond the Laboratory: Bridging the Gap Between Academic Research and Industry
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The mass production of graphene oxide (GO) has garnered significant attention in recent years due to its potential applications in various fields, from materials science to biomedicine. Graphene, known for its unique properties, such as high conductivity and mechanical strength, has been extensively studied. However, traditional production methods such as the exfoliation of graphite with scotch tape are not suitable for large-scale production. This has led to an increased focus on GO as a viable alternative to graphene production. Nonetheless, challenges, including the optimization of oxidation processes, the control of structural uniformity, and the reproducibility of production, have not been solved so far. This review critically examines GO production advancements by analyzing experimental and mechanistic studies to identify significant developments that enable high-yield and reproducible methods suitable for industrial-scale production. Special attention is given to oxidation techniques and postsynthesis purification and storage, with a focus on controlled oxidation to achieve homogeneous and single-layer GO. Through this lens, the review outlines the path forward for the industrialization of GO, aiming to bridge the gap between academic research and industrial production.

kn-title=Refined surface area determination of graphene oxide using methylene blue as a probe molecule: a comparative approach
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this research, we explored the effectiveness of the methylene blue adsorption method as an alternative approach for determining the specific surface area of graphene oxide. Initially, through a comparative analysis with reference activated carbon, we identified the limitations of utilizing N2 physisorption for specific surface area determination of graphene oxide. Our findings revealed that the standard pretreatment process (heating under vacuum) before N2 physisorption led to damage to the surface oxygen groups on graphene oxide, and the measured surface areas (43?m2/g) do not accurately represent the entire surface area. To optimize methylene blue coverage on graphene oxide, we conducted adsorption equilibrium experiments, focusing on controlling temperature and pH. The pH was significantly important in regulating the coverage of methylene blue. Under the optimized methylene blue adsorption conditions, the specific surface area of graphene oxide was 1,555?m2/g. Our assumptions regarding specific surface area calculations were supported by structural characterization of samples with varying methylene blue uptakes. The results confirmed a uniform coverage of methylene blue on graphene oxide by scanning electron microscopy and energy dispersive X-ray, X-ray diffraction, and atomic force microscopy.

kn-title=The Design and Implementation of Kerberos-Blockchain Vehicular Ad-Hoc Networks Authentication Across Diverse Network Scenarios
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Vehicular Ad-Hoc Networks (VANETs) play an essential role in the intelligent transportation era, furnishing users with essential roadway data to facilitate optimal route selection and mitigate the risk of accidents. However, the network exposure makes VANETs susceptible to cyber threats, making authentication crucial for ensuring security and integrity. Therefore, joining entity verification is essential to ensure the integrity and security of communication in VANETs. However, to authenticate the entities, authentication time should be minimized to guarantee fast and secure authentication procedures. We propose an authentication system for VANETs using blockchain and Kerberos for storing authentication messages in a blockchain ledger accessible to Trusted Authentication Servers (TASs) and Roadside Units (RSUs). We evaluate the system in three diverse network scenarios: suburban, urban with 1 TAS, and urban with 2 TASs. The findings reveal that this proposal is applicable in diverse network scenarios to fulfill the network requirements, including authentication, handover, and end-to-end delay, considering an additional TAS for an increasing number of vehicles. The system is also practicable in storing the authentication message in blockchain considering the gas values and memory size for all scenarios.

kn-title=Conformational Flexibility of D1-Glu189: A Crucial Determinant in Substrate Water Selection, Positioning, and Stabilization within the Oxygen-Evolving Complex of Photosystem II
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Photosynthetic water oxidation is a vital process responsible for producing dioxygen and supplying the energy necessary to sustain life on Earth. This fundamental reaction is catalyzed by the oxygen-evolving complex (OEC) of photosystem II, which houses the Mn4CaO5 cluster as its catalytic core. In this study, we specifically focus on the D1-Glu189 amino acid residue, which serves as a direct ligand to the Mn4CaO5 cluster. Our primary goal is to explore, using density functional theory (DFT), how the conformational flexibility of the D1-Glu189 side chain influences crucial catalytic processes, particularly the selection, positioning, and stabilization of a substrate water molecule within the OEC. Our investigation is based on a hypothesis put forth by Li et al. (Nature, 2024, 626, 670), which suggests that during the transition from the S2 to S3 state, a specific water molecule temporarily coordinating with the Ca ion, referred to as O6*, may exist as a hydroxide ion (OH-). Our results demonstrate a key mechanism by which the detachment of the D1-Glu189 carboxylate group from its coordination with the Ca ion allows the creation of a specialized microenvironment within the OEC that enables the selective attraction of O6* in its deprotonated form (OH-) and stabilizes it at the catalytic metal (MnD) site. Our findings indicate that D1-Glu189 is not only a structural ligand for the Ca ion but may also play an active and dynamic role in the catalytic process, positioning O6* optimally for its subsequent participation in the oxidation sequence during the water-splitting cycle.

kn-title=Ferrimagnetic structure in the high-pressure phase of ??Mn
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The ??Mn phase exhibits a large anomalous Hall effect (AHE) in its pressure-induced weak ferromagnetic (WFM) state, despite its relatively small spontaneous magnetization of ?0.02?B/Mn. To understand the underlying mechanism behind this AHE, we performed single crystal neutron diffraction measurements at 2.0 GPa to determine the magnetic structure of the WFM phase. Our investigation reveals a ferrimagnetic structure characterized by nearly collinear magnetic moments aligned along the [001] direction at sites I, II, III-1, and IV-1. In contrast, the small moments at sites III-2 and IV-2 lie within the (001) plane. The calculated net magnetization of this magnetic structure, (?0.08±0.10)??B/Mn atom, is in agreement with the experimentally determined spontaneous magnetization. The observation of a magnetic reflection at ?=(0,0,0) satisfies a key condition for the emergence of the AHE.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Carbon dioxide (CO2) serves as a cheap, abundant, and renewable C1 building block for the synthesis of organic compounds and polymers. Selective and efficient CO2 fixation processes are still challenging because of the kinetic and thermodynamic stability of CO2. Among various CO2 fixation processes, the ring-opening copolymerization (ROCOP) of epoxides and CO2 gives aliphatic polycarbonates with high atom economy, although the chemical and physical properties of the resulting polycarbonates are not necessarily satisfactory. Introducing the third monomers into this ROCOP system provides new terpolymers, and the thermal, optical, mechanical or degradation properties can be added or tuned by incorporating new polymer backbones derived from the third monomers at the expense of the CO2 content. Here we review the terpolymerization reactions of epoxides, CO2, and the third monomers such as cyclic anhydrides, lactones, lactides, heteroallenes, and olefins. The development of catalysts and the control of the polymer structures are described together with the chemical and physical properties of the resulting polymers.

kn-title=Effect of Vibration Behavior in Low-Frequency Vibration Cutting on Surface Properties of Workpiece
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=　The objective of this study was to determine the effect of vibration behavior on workpiece surface properties in low-frequency vibration cutting. The effects of the parameters that determine vibration behavior on surface roughness were quantitatively evaluated through a comparison with other cutting conditions. Furthermore, by clarifying how the surface properties of the workpiece, such as roughness, roundness, and cross-sectional curves, change depending on the vibration behavior, a search for optimal conditions for low-frequency vibration cutting was conducted. The best surface properties were obtained under the condition of spindle rotation per vibration E=4.5. By using a value close to the minimum possible spindle rotation R=0.5 when the workpiece is retracted, it is expected to be effective in suppressing the variation in surface roughness at each phase angle; this variation is characteristic of low-frequency vibration cutting. Workpieces machined under low-frequency vibration conditions such as (E=2.5, R=1.0) and (E=3.5, R=1.0) were found to form characteristic surface patterns on the workpiece surface owing to a phenomenon in which the depth of the cut to the workpiece changes.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Anodic oxidation?promoted SNAr reactions of electron-rich aryl fluoride were developed. The anodic oxidation of 4-fluoroanisole in hexafluoroisopropyl alcohol (HFIP) with K2CO3 led to SNAr-type hexafluoroisopropoxylation, and the reaction was completed with a catalytic electrical input. The results of cyclic voltammetry suggest that the radical cation of 4-fluoroanisole, which would react with the alkoxide of HFIP, is generated. Electron transfer between the intermediate and the starting material constructs the catalytic cycle, and the elimination of fluoride from the Meisenheimer complex produces the desired compound.

kn-title=Colossal Dielectric Constant of Nanocrystalline/Amorphous Homo-Composite BaTiO3 Films Deposited via Pulsed Laser Deposition Technique

kn-abstract=We report the pulsed laser deposition (PLD) of nanocrystalline/amorphous homo-composite BaTiO3 (BTO) films exhibiting an unprecedented combination of a colossal dielectric constant (epsilon(r)) and extremely low dielectric loss (tan delta). By varying the substrate deposition temperature (T-d) over a wide range (300-800 degrees C), we identified T-d = 550 degrees C as the optimal temperature for growing BTO films with an epsilon(r) as high as similar to 3060 and a tan delta as low as 0.04 (at 20 kHz). High-resolution transmission electron microscopy revealed that the PLD-BTO films consist of BTO nanocrystals (similar to 20-30 nm size) embedded within an otherwise amorphous BTO matrix. The impressive dielectric behavior is attributed to the combination of highly crystallized small BTO nanograins, which amplify interfacial polarization, and the surrounding amorphous matrix, which effectively isolates the nanograins from charge carrier transport. Our findings could facilitate the development of next-generation integrated dielectric devices.

kn-title=Detecting Unintended Redirects to Malicious Websites on Android Devices Based on URL-Switching Interval
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Website clicks that redirect Android-phone users to malicious websites with fake virus alerts or phishing attacks are increasing exponentially. Although a uniform resource locator (URL) blocklist is considered a suitable countermeasure to such attacks, it is difficult to efficiently identify malicious websites. To the best of our knowledge, no research has focused on detecting attacks that redirect Android-phone users to malicious websites. Therefore, we propose a redirect-detection method that focuses on the URL bar-switching interval of Android-based Google Chrome browser. The proposed method, which can be easily installed as an Android application, uses the Android accessibility service to detect unintended redirects to malicious websites without collecting information about these websites in advance. This paper details the design, implementation, and evaluation results of the proposed application on an actual Android device. We determined the threshold values for the number of times the URL bar switches and the elapsed time to determine redirects to malicious websites for the proposed method. Based on the results, we investigated the causes of false-positive detection of redirects to benign websites and offer solutions on handling them. We also present the threshold values that can minimize the false positive and negative rates, as well as the detection accuracy of the proposed method based on these threshold values. Additionally, we present the evaluations results based on the access logs of actual users participating in the WarpDrive project experiment, which indicate that the proposed method minimizes false positives and successfully detects most redirects to malicious websites.
