To explore the structural equation model to explore the levels of work-related musculoskeletal disorders (WMSDs) and various risk factors in the feet and ankle of China's occupational population, providing scientific basis for for preventing WMSDs in feet and ankles. Data of 73497 national occupational epidemiological cases were selected from June 2018 to December 2023 used the Chinese version of the Electronic Questionnaire on Musculoskeletal Disorders. The adverse ergonomic factors and their source classification standard and confirmatory factor analysis were used to investigate foot and ankle WMSDs and their related risk factors (including individual factors, work organization, work posture, work type, fatigue, etc.

Lattice deformations in graphene couple to the low-energy electronic degrees of freedom as effective scalar and gauge fields. Using molecular dynamics simulations, we show that the optical component of the displacement field, i.e.

We revisit the decay rate of the electroweak vacuum in the standard model with the full one-loop prefactor. We focus on the gauge degrees of freedom and derive the degeneracy factors appearing in the functional determinant using group theoretical arguments. Our treatment shows that the transverse modes were previously overcounted, so we revise the calculation of that part of the prefactor.

Nanoelectromechanical systems (NEMS) based on atomically-thin tungsten diselenide (WSe), benefiting from the excellent material properties and the mechanical degree of freedom, offer an ideal platform for studying and exploiting dynamic strain engineering and cross-scale vibration coupling in two-dimensional (2D) crystals. However, such opportunity has remained largely unexplored for WSe NEMS, impeding exploration of exquisite physical processes and realization of novel device functions. Here, we demonstrate dynamic coupling between atomic lattice vibration and nanomechanical resonances in few-layer WSe NEMS.

We investigated the association between values and attitudes toward sexual and reproductive health and rights (SRHR) and gender equality, with reproductive agency in Ethiopia, Kenya, and Zimbabwe. Using 2020-21 World Values Survey (WVS) data ( = 3096), we utilised the SRHR Support Index including five subindices to gauge SRHR attitudes, the WVS Equality Index for gender equality values, and the perceived level of freedom of choice and control over whether, when, and how many children to have as a proxy for reproductive agency. Descriptive statistics, bivariate, and multivariable logistic regressions were used to analyse how values and attitudes differed between respondents of high vs low reproductive agency using the median as cut-off, stratified by country and sex.
