Remaining Useful Life Prediction of Rolling Bearings Based on Multi-Scale Attention Residual Network.

The remaining useful life (RUL) prediction of rolling bearings based on vibration signals has attracted widespread attention. It is not satisfactory to adopt information theory (such as information entropy) to realize RUL prediction for complex vibration signals. Recent research has used more deep learning methods based on the automatic extraction of feature information to replace traditional methods (such as information theory or signal processing) to obtain higher prediction accuracy.

The Effect of Critical Thinking on Translation Technology Competence Among College Students: The Chain Mediating Role of Academic Self-Efficacy and Cultural Intelligence.

Background: It is increasingly essential for translators to possess a high level of technological proficiency to succeed in their work, as technology is becoming an integral part and common practice of the translation industry. Several previous studies found that critical thinking, academic self-efficacy, and cultural intelligence independently influenced the translation competence of college students. However, the underlying psychological mechanism through which these salient factors affect student translators' technology competence has not been fully explored.

Thus, the PM concentration needs to be further reduced.

Insight into the Mechanism and Kinetics of the Heterogeneous Reaction between SO and NO on Diesel Black Carbon under Light Irradiation.

The heterogeneous oxidation of SO by NO has been extensively proposed as an important pathway of sulfate production during haze events in China. However, the kinetics and mechanism of oxidation of SO by NO on the surface of complex particles remain poorly understood. Here, we systematically explore the mechanism and kinetics of the reaction between SO and NO on diesel black carbon (DBC) under light irradiation.

Research Progress on Multifunctional Modified Separator for Lithium-Sulfur Batteries.

Lithium-sulfur batteries (LSBs) are recognized as one of the second-generation electrochemical energy storage systems with the most potential due to their high theoretical specific capacity of the sulfur cathode (1675 mAhg), abundant elemental sulfur energy storage, low price, and green friendliness. However, the shuttle effect of polysulfides results in the passivation of the lithium metal anode, resulting in a decrease in battery capacity, Coulombic efficiency, and cycle stability, which seriously restricts the commercialization of LSBs. Starting from the separator layer before the positive sulfur cathode and lithium metal anode, introducing a barrier layer for the shuttle of polysulfides is considered an extremely effective research strategy.

Improving the prediction accuracies of economically important traits in genomic selection (GS) is a main objective for researchers and breeders in the livestock industry. This study aims at utilizing potentially functional SNPs and QTLs identified with various genome-wide association study (GWAS) models in GS of pig growth traits. We used three well-established GWAS methods, including the mixed linear model, Bayesian model and meta-analysis, as well as 60K SNP-chip and whole genome sequence (WGS) data from 1734 Yorkshire and 1123 Landrace pigs to detect SNPs related to four growth traits: average daily gain, backfat thickness, body weight and birth weight.

CoO/CoFeO Hollow Nanocube Multifunctional Nanozyme with Oxygen Vacancies for Deep-Learning-Assisted Smartphone Biosensing and Organic Pollutant Degradation.

Although the application of nanozymes has been widely studied, it is still a huge challenge to develop highly active and multifunctional nanozyme catalysts with a wider application prospect. CoO/CoFeO hollow nanocubes (HNCs) with oxygen vacancies were proposed in this study, which had a porous oxide heterostructure with CoFeO as the core and CoO as the shell. The CoO/CoFeO HNCs had three enzyme activities: peroxidase-like, oxidase-like, and catalase-like.

In this study, we report several newly isolated bacillus strains with superior performances in metabolizing phenols, one of which showed paramount efficiencies to metabolize phenol at concentrations up to 1200 mg L and could simultaneously degrade a wide range of other phenolic compounds.

The role of histone methylase and demethylase in antitumor immunity: A new direction for immunotherapy.

Epigenetic modifications may alter the proliferation and differentiation of normal cells, leading to malignant transformation. They can also affect normal stimulation, activation, and abnormal function of immune cells in the tissue microenvironment. Histone methylation, coordinated by histone methylase and histone demethylase to stabilize transcription levels in the promoter area, is one of the most common types of epigenetic alteration, which gained increasing interest.

Immune infiltration and immunophenotyping in atrial fibrillation.

Atrial fibrillation (AF) is a relatively common arrhythmia in clinical practice.
