Summary: Recent cosmological observations and compatible theory provide insights into dark matter and dark energy, while the conformal theory presented here offers an explanation that does not require dark matter and aligns with observed phenomena. This theory suggests the existence of a massive neutral particle or resonance W-2 at 125 GeV, which interacts strongly through quark exchange and could account for the LHC 125 GeV resonance. The inclusion of a massless scalar field dressed by the W-2 field provides a framework for understanding the Higgs Lagrangian term λ(Φ†Φ)² with the known empirical value of λ from astrophysics.

Summary: The original unidimensional Mini-BESTest model with a total score of 28 showed the highest validity and reliability and was best at discriminating fallers from nonfallers. However, its 4 subsections should not be reported separately, because they were highly correlated and had low reliability.

Summary: This article introduces a second-order coupled tristable stochastic resonance system based on an adaptive genetic algorithm, which is used for detecting mechanical fault signals. Through comparative analysis of different control systems and the study of parameter influences, it is proven that the performance of this system is superior to first-order systems and has better denoising ability. In simulation experiments and practical applications, this system demonstrates better fault detection capabilities.

Summary: In recent years, machines have been able to recognize and analyze human emotions through the rapid development of sensors and information technology. Emotion recognition is an important research direction in various fields and can be achieved by analyzing facial expressions, speech, behavior, or physiological signals. This survey collects and reviews over 200 papers on emotion recognition, categorizes them according to different innovations, compares the advantages and disadvantages of different sensors, and provides application examples and developments in emotion recognition. It aims to help researchers understand existing emotion recognition systems and make informed choices of sensors, algorithms, and datasets.

Summary: Bacteria have evolved multiple signal transduction systems to adapt to changing environmental conditions. The chemoreceptor McpA of Bacillus velezensis SQR9 has been found to directly bind to 13 chemoattractants. Structural biology studies and mutagenesis experiments have identified key amino acid residues that play roles in recognizing multiple ligands. This discovery reveals a mechanism in which a single chemoreceptor can integrate diverse signals through two modules.

Summary: This paper discusses the phenomenological models of mechanochemical corrosion kinetics and their application in predicting the lifetime of thin-walled cylindrical and spherical shells under different pressures and temperatures. Closed-form solutions for both one-sided and double-sided corrosion are presented, which consider various temperature effects such as corrosion rate, inhibition, maximal stress of the shell material, coating lifetimes, and the mechanochemical effect and bearing capacity factor by changing thermo-elastic stresses.

Summary: In this study, the discrepancy between the existing model of duty-cycle controlled resonant converters and simulation/experimental results was found. It was discovered that the phase change in the output voltage of the inverter bridge caused by duty-cycle perturbation was ignored in the existing model. The phase change law is highly dependent on the duty-cycle scheme used and different schemes lead to different phase curves of the duty-cycle-to-output-voltage transfer functions. Care should be taken when selecting the appropriate duty-cycle control scheme.

Summary: This study aimed to evaluate the impact of the blood-brain barrier on neuronal gadolinium deposition after multiple intravenous injections of gadodiamide in mice. The results showed that multiple administrations of gadodiamide led to cerebral gadolinium deposition without imaging correlate in MRI.

Summary: Mitochondrial impairment plays a significant role in psychiatric disorders, and animal models are essential for studying bioenergetic deficits in these diseases. Models of depression, bipolar disorder, schizophrenia, and autism show shared patterns of brain energy impairment, indicating a lack of disease-specific brain energy phenotype in humans.
