Entertainment Sedentary Time and Subjective Well-Being in College Students: A Moderation Model of Perceived Time Poverty

This study examined the association between entertainment sedentary time (EST) and subjective well-being (SWB) among Chinese college students and further explored the moderating role of perceived time poverty (PTP). A total of 1582 college students completed questionnaires assess...

Breathing ferroelectricity, flat-bands and multiple chiral phonons in van der Waals breathing kagome Nb3Cl8

Van der Waals layered Nb3X8 (X=Cl, Br, I) are predicted to integrate multiple intriguing physical properties, notably multiferroicity and flat-bands that are highly promising for novel-principle memories and superconductors. However, direct experimental validations such as the pr...

Joint effects and mediating mechanisms of body roundness index and biological aging on the risk of incident cardiovascular disease: a nationally representative prospective cohort study

Body roundness index (BRI) and biological aging are critical drivers of cardiovascular disease (CVD). However, their joint pathogenic effects and underlying mechanisms in the development of CVD remain elusive. This study aims to investigate the independent and joint effects of BR...

The influence of MoS 2 lubricity on the secondary cutting performance of PCD micro-groove textured tools

Micro-textured cutting tools possess unique advantages in reducing cutting forces, lowering chip temperatures, minimizing tool wear, and improving machined surface quality. Nevertheless, the secondary cutting effect induced by micro-textures impairs texture integrity and aggravat...
