To study the specific features of the burnout syndrome (BOS) in communicative professional workers, the authors examined 138 communicative workers (94 females and 44 males); of them there were 51 physical education masters, 43 elementary school teachers, 20 consulting shop assistants, and 24 legal officers. BOS was detected in more than two thirds of elementary school teachers and more than a third of physical education masters, consulting shop assistants, legal officers, and practitioners. The completely developed BOS was most frequently encountered in elementary school teachers (in every four individuals), slightly less frequently in practitioners, consulting shop assistants, and legal officers (in every ten persons). The highest BOS levels were observed in elementary school teachers having a service length of less than 5 years and in legal officers and practitioners having a service length of more than 10 years. The paper provides evidence for the expediency of complex preventive measures for the representatives of these professions and for psychological support of their professional activities.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Importance: Disparities in cognition, including dementia occurrence, persist between non-Hispanic Black (hereinafter, Black) and non-Hispanic White (hereinafter, White) older adults, and are possibly influenced by early educational differences stemming from structural racism. However, the association between school racial segregation and later-life cognition remains underexplored.
Objective: To investigate the association between childhood contextual exposure to school racial segregation and cognitive outcomes in later life.

A fundamental manifestation of the nontrivial correlations of an incompressible fractional quantum Hall (FQH) state is that an electron added to it disintegrates into more elementary particles, namely fractionally-charged composite fermions (CFs). We show here that the Girvin-MacDonald-Platzman (GMP) density-wave excitation of the ν=n/(2pn±1) FQH states also splits into more elementary single CF excitons. In particular, the GMP graviton, which refers to the recently observed spin-2 neutral excitation in the vanishing wave vector limit [Liang et al.

Background: Individuals with both type 2 diabetes mellitus (T2DM) and hypertension have an increased risk of cognitive impairment (CI) compared to those with either T2DM or hypertension. Therefore, this study aims to identify the prevalence of CI and its associated factors in T2DM patients with hypertension in Hunan, China.
Methods: This cross-sectional study included T2DM patients with hypertension admitted to the Department of Endocrinology of Yuanjiang People's Hospital in Hunan Province from July 2022 to February 2023.

Background: The purpose of this study is to explore the association between class-level factors, such as lesson start time, class size, lesson location, PE content, and PE context, and student engagement in moderate-to-vigorous physical activity (MVPA) during PE lessons in both elementary and middle schools.
Methods: A total of 284 PE lessons from ten schools in Shanghai, Eastern China, were included in the study. Students' MVPA during PE lessons was recorded using accelerometry, and lesson context was evaluated using the System for Observing Fitness Instruction Time (SOFIT).
