Latent profile analysis of social alienation and its influencing factors in patients undergoing maintenance hemodialysis

Social alienation severely impairs the mental health and quality of life of patients undergoing maintenance hemodialysis (MHD). However, most studies conducted have been variable-centered, group-level analyses, which cannot capture inherent heterogeneity in social alienation, hin...

Causal association between air pollution and functional outcome after ischemic stroke: Evidence from 2-sample MR study

Observational studies have shown that air pollution may affect functional outcome following ischemic stroke. Our study aimed to explore the relationship between genetically predicted specific air pollutants and poststroke functional outcomes using the Mendelian randomization (MR)...

Research on the dynamic evolution of competitive and water-film-mediated wear mechanisms of the carbon strips in the pantograph-catenary system at low temperature

Abstract To investigate the evolution of wear mechanisms in carbon strips at low temperature, this study conducted comparative friction tests on copper-impregnated carbon strips at room temperature (25 °C) and low temperature (-20 °C). To replicate operating conditions, the exper...
