ABSTRACTMicro‐supercapacitors (mSCs) have emerged as next‐generation energy storage components suitable for portable, flexible, and eco‐friendly electronic device system. In particular, electric double‐layer (EDL) mSCs utilizing flexible graphene electrodes have gained significant attention due to their quick and efficient charge/discharge capabilities. Despite significant progress in fabricating mSCs, particularly through the development of laser‐induced graphene (LIG) for creating 3D porous electrodes, challenges remain in increasing both energy and power densities. One promising strategy to address these challenges is the incorporation of pseudo‐capacitive materials into the 3D graphene structure. However, conventional methods for embedding pseudo‐capacitive materials often involve complex and additional labor‐intensive steps to the manufacturing process. In this work, we introduce a high‐speed mSC fabrication method (< 5 min) that employs a continuous laser‐scribing process to directly integrate Mn2O3, a pseudo‐capacitive material, onto LIG electrodes, forming hierarchical Mn2O3/LIG structure. By precisely controlling the fabrication parameter, this approach can significantly improve the electrochemical performance by optimizing the density and thickness of Mn2O3, leading to 550.5% increase in capacitance and energy density compared to the LIG electrode. Additionally, the mSCs exhibit outstanding cyclic (> 88% @ 20,000 cycles) and mechanical stability (@ bending radius of 5 mm), confirming their potential for seamless integration into electronic circuits. This innovation not only simplifies the production process of high‐performance mSCs but also broadens their potential applications in sustainable and compact electronic device system.

ABSTRACTDue to the strong affinity between the solvent and Li+, the desolvation process of Li+ at the interface as a rate‐controlling step slows down, which greatly reduces the low‐temperature electrochemical performance of lithium‐ion batteries (LIBs) and thus limits its wide application in energy storage. Herein, to improve the low‐temperature tolerance, a localized high‐concentration electrolyte based on weak solvation (Wb‐LHCE) has been designed by adding a diluent hexafluorobenzene (FB) in a weak solvating solvent tetrahydrofuran (THF). Combining theoretical calculations with characterization tests, it is found that with the addition of diluent FB, the dipole–dipole interaction between the diluent and the solvent causes FB to compete with Li+ for THF. This competition causes the solvent to move away from Li+, weakening the binding energy between Li+ and THF, whereas the anions are transported into the solvation shell of Li+, forming an anion‐rich solvation structure. In addition to accelerating the Li+ desolvation process, this unique solvation structure optimizes the composition of the CEI film, making it thin, dense, homogeneous, and rich in inorganic components, and thus improving the interfacial stability of the battery. As a result, the assembled LiFePO4/Li half‐cell shows excellent electrochemical performances at low temperature. That is, it can maintain a high discharge specific capacity of 124.2 mAh g−1 after 100 cycles at a rate of 0.2C at −20°C. This provides an attractive avenue for the design of advanced low‐temperature electrolytes and improvement of battery tolerance to harsh conditions.
Advanced Gesture Recognition Method Based on Fractional Fourier Transform and Relevance Vector Machine for Smart Home Appliances
Authors: Hong‐qin Xie , Yuan‐yuan Zhao 
Published: January 2025

ABSTRACTAddressing the challenges of low feature extraction dimensions and insufficient distinct information for gesture differentiation for smart home appliances, this article proposed an innovative gesture recognition algorithm, integrating fractional Fourier transform (FrFT) with relevance vector machine (RVM). The process involves using FrFT to transform raw gesture data into the fractional domain, thereby expanding the dimensions of information extraction. Subsequently, high‐dimensional feature vectors are created from fractional domain, and RVM classifiers are employed for joint optimization of feature selection and classification decision functions, achieving optimal classification performance. A dataset was constructed using five different types of gestures recorded on the TI millimeter‐wave radar platform to validate the effectiveness of this method. The experimental results demonstrate that the RVM selected the optimal FrFT order of 0.6, with the best feature set comprising fractional spectral entropy, peak factor, and second‐order central moment. Recognition rates for each gesture exceeded 96.2%, with an average rate of 98.5%. This performance surpasses three comparative methods in both recognition accuracy and real‐time processing, indicating high potential for future applications.

ABSTRACTPatients with type 2 diabetes mellitus (DM) are more susceptible to microvascular complications. However, whether DM is associated with coronary microvascular dysfunction (CMD) is unclear. This observational study used data from the Coronary Microvascular Disease Registry (CMDR) (NCT05960474) and included patients with angina and no obstructive coronary artery disease (ANOCA) who underwent invasive CMD evaluation using the CoroVentis CoroFlow System (Abbott Vascular, Santa Clara, CA). Patient demographics, comorbidities, laboratory data, echocardiography, coronary angiography, and microvascular physiology results were analyzed. Among the 271 patients, 73 (26.9%) had DM. These patients were more likely to be African American (68.1% vs. 47.0%) and had higher rates of hypertension (93.2% vs. 74.2%), hyperlipidemia (89.0% vs. 68.7%), and chronic kidney disease (17.8% vs. 8.1%) than those without DM. Invasive coronary functional testing showed no significant differences in the index of microcirculatory resistance (IMR) (17.82 ± 8.17 vs. 19.37 ± 13.14, p = 0.268) or coronary flow reserve (CFR) (3.24 ± 1.73 vs. 3.21 ± 1.86, p = 0.909) between diabetic and nondiabetic patients. Similarly, in those testing positive for CMD, there were no significant differences in IMR (27.8 ± 7.4 vs. 32.35 ± 15.22, p = 0.108) or CFR (2.42 ± 1.09 vs. 2.05 ± 0.94, p = 0.199). Although patients with DM exhibited more comorbidities, CMD physiology indices were comparable between the groups.

Published: January 2025

ABSTRACTStatic limit analysis is one of the primary methods for analyzing the failure of masonry arch vaults. The limit analysis method for masonry arch was initially developed for gravity load analysis of the masonry arch vaults and later extended for lateral dynamic loads. The limit analysis theory neglects any tensile strength at the joints of the blocks. However, this assumption is not true for all types of arches, especially mortar‐bonded arches and continuous cohesive arches. In the current study, the shake table experiments were conducted on small‐scale masonry bonded arches, and their behavior was simulated in the finite element (FE) environment. The reinforced arch vaults with Engineered Cementitious composite (ECC) were also tested on the shake table, and their performance was found to be significantly improved in dynamic lateral loads. Taking into consideration the behavior of the experimental and FE models, the current theory of limit analysis for masonry arch vaults was modified for mortar bonded arch with finite tensile strength. The limit loads derived from the formulation and the limit loads obtained from analyzing the FE model showed a strong agreement in their results. Limit load analysis was also performed for the ECC reinforced arch, and the results showed a significant increase in the lateral load‐carrying capacity of the ECC reinforced arch.
Seismic Design and Fragility of Self‐Centering Bridge Bent With Replaceable Stretch Length Anchors
Authors: Neupane Suman , Pantelides Chris P. 
Published: January 2025

ABSTRACTSeismic performance assessment of a modified two‐column bridge bent of an existing bridge is presented. The columns of the existing bridge are posttensioned with high strength steel bars. The modified bridge bent combines self‐centering, from unbonded posttensioned (PT) bars with low initial posttensioning stress in the columns, with energy dissipation by replaceable external stretch length anchors (SLAs) attached at the column ends. SLAs are replaceable anchors that dissipate hysteretic energy through tension‐only action without buckling or any significant reduction of column self‐centering ability. An analysis method for evaluating the nonlinear static pushover of the modified bridge bent is described and validated with experiments. A fiber‐based numerical model of the bridge bent is developed in OpenSees. The OpenSees model is used to perform cyclic and time history analyses of the three configurations with PT bars and SLAs and develop fragility functions for the maximum likelihood estimation (MLE) of damage parameters based on the drift ratio. The fragility functions show that the modified Riverdale Bridge bent with SLAs can withstand a spectral acceleration of 3.3 × g for both near‐field (NF) and far‐field (FF) earthquakes while maintaining excellent self‐centering performance. The presence of replaceable SLAs contributes to the redundancy and functionality of the lateral force resisting system. The analysis method and fragility functions for the maximum drift ratio and the maximum residual drift can be used in performance‐based seismic design of self‐centering bridge bents with SLAs.
Influence of Seismic Direction on Dynamic Responses of Wind Turbine in Operation: An Experimental Study by Combining Wind Tunnel and Shaking Table Tests
Authors: Ma Baowei , Zhou Annan , Lin Kun 
Published: January 2025

ABSTRACTThis study investigates dynamic responses of wind turbines subjected to combined seismic and wind loads, with a particular focus on the influence of seismic input angles and the effect of aerodynamic damping. A wind tunnel‐shaking table (WTST) test platform was developed, capable of applying seismic and wind loads simultaneously. A 1:100 scale model wind turbine was tested using El‐Centro and Taft seismic records, sourced from the Pacific Earthquake Engineering Research (PEER) Strong Ground Motion Database, which were adjusted for amplitude and time to simulate realistic loading conditions. The experiments included a fixed wind input direction and seven different seismic input directions across six operational conditions (including the parked condition) to assess the influence of seismic direction on the dynamic responses of wind turbines in operation. The results show that as the seismic input angle increases from 0° to 180°, nacelle displacement initially decreases and then increases, with similar trends in nacelle acceleration and vibration. Increasing wind speed leads to a gradual reduction in nacelle displacement. While the standard deviation of acceleration initially decreases as the turbine transitions from stopped to operational, it becomes wind‐speed independent thereafter. The peak tower moment occurs in the side‐to‐side (S‐S) direction at a seismic input angle of 90°, and the acceleration amplification factor can soar to 4 at 0° and 180° seismic input angles, indicating up to a fourfold magnification of input acceleration at the nacelle. This study provides experimental evidence that seismic direction and aerodynamic damping are critical factors when evaluating the safety and reliability of operational wind turbines in earthquake‐prone areas.

ABSTRACTObjectiveThis study investigated the impact of 2019 coronavirus disease (COVID‐19) lockdowns on alcohol consumption and smoking behavior among young adults from Germany.MethodsAn online survey was completed by N = 317 young adults living in Germany. Of these, 140 (44.2%) consumed alcohol and were included in the analysis. They reported on alcohol consumption, hangover frequency and severity, and smoking behavior across four time periods: (1) “BP” (the period before the COVID‐19 pandemic), (2) “L1” (the first lockdown; March–May, 2020), (3), NL1 (the no lock‐down period; summer 2020), and (4) L2 (the second lockdown, November 2020 to May 2021).ResultsDuring L1, a significant decrease was observed in weekly alcohol intake, the number of drinking days, and the number of days where more than eight alcoholic drinks were consumed. Whereas hangover frequency was significantly increased during L1, hangover severity was significantly reduced. During NL1, drinking behaviors returned to BP levels. During L2, the decrease in alcohol consumption was much smaller, and not significantly different from BP. However, compared to BP, during L2 hangover frequency was significantly increased and hangover severity was significantly reduced. With regards to smoking, no significant differences compared to BP were found.ConclusionsDuring the COVID‐19 lockdown periods in Germany, a significant decrease in alcohol consumption was observed among this group of young adults. Whereas hangover frequency was significantly increased during the lockdown periods, hangover severity was significantly reduced.
“Cell dedifferentiation” versus “evolutionary reversal” theories of cancer: The direct contest of transcriptomic features
Authors: Vinogradov Alexander E. , Anatskaya Olga V. 
Published: January 2025

AbstractCell dedifferentiation is considered an important hallmark of cancer. The atavistic reversal to a unicellular‐like (UC) state is a less widely accepted concept, so far not included in the conventional hallmarks. The activated expression of ontogenetically earlier and evolutionary earlier genes in cancers supports both theories because ontogenesis partially recapitulates phylogenesis during cell differentiation (the cellular biogenetic law). We directly contested both types of gene signatures in stem vs. differentiated and cancer vs. normal cells, using meta‐analysis of human single‐cell transcriptomes (totally, 38 pairwise comparisons involving over 18,600 cells). Because compared cells can differ in proliferation rate, the correction for cell cycle activity was applied. Taken together as multiple variables in stem vs. differentiated cells analyses, the ontogenetic signature excluded the UC signature from predictive variables, usually even forcing it to change the sign of prediction (from plus to minus). In contrast, in cancer vs. normal cells, the UC signature excluded the ontogenetic signature. Thus, the direct contest decided in favor of the atavistic theory and placed a UC‐like state as a central hallmark of cancer, which has a plausible evolutionarily formed mechanism (UC attractor) and can generate other hallmarks. These data suggest a paradigm shift in the understanding of oncogenesis and propose an integrative framework for cancer research. In a practical sense, the upregulation of UC signature over ontogenetic signature indicates potential tumorigenicity, which can be used in early diagnostics and regenerative medicine. For therapy, these results suggest the UC center of cellular networks as a universal target.

ABSTRACTObjectivesPrevious research highlights the strong correlation between certain personality traits and individual career adaptability levels, yet the role of competitive personality remains underexplored. This study aims to fill the gaps by assessing the relationship between competitive attitudes and career adaptability among Chinese college students.MethodsA multi‐stage stratified random sampling approach was used to conduct a cross‐sectional survey of 692 undergraduate students from a top university in China. The final sample comprised 22.11% females and 77.89% males, aged 18−24, with a mean age of 19.54 years (SD = 2.16). Pearson's correlation and multiple linear regression analyses were utilized to examine the relationship between competitive attitudes and career adaptability.ResultsResults showed that the average scores among college students were 10.068 for feelings for competition, 8.876 for beliefs about competition, and 7.802 for behavioral tendencies of competition. Significant gender differences were observed across all three dimensions (p < 0.01). In terms of career adaptability, the average scores for career concern, career control, career curiosity, and career confidence were 14.802, 15.601, 15.678, and 15.828, respectively, with no significant gender differences. Feelings for the competition had significantly negative impacts on career control and career curiosity (with coefficients of −0.149 and −0.110, respectively). Conversely, beliefs about competition had significant positive effects on career concern, control, curiosity, and confidence (with coefficients of 0.223, 0.200, 0.207, and 0.162, respectively).ConclusionsThe findings suggest that feelings for competition hinder the development of career adaptability, whereas beliefs about competition contribute positively to enhancing career adaptability.
