Psychological distress has been a growing challenge to healthy living worldwide. Special attention concentrated on examining the cost of psychological life satisfaction college students who are vulnerable groups coping with challenge. The purpose this study is explore roles physical literacy (PL) and mindfulness in mediating impact among China.

The study aims to examine the mediation effects of physical literacy and activity behavior in a relationship between psychological distress life satisfaction among Chinese college students during real-life Coronavirus disease pandemic (COVID-19) circumstance. This implemented cross-sectional design, 1,516 participants from 12 universities participated this study. Structural equation modeling was used hypothesized model. findings indicated an acceptable model fit (X2[61] = 508.2, Comparative...

In this paper, a three-dimensional eco-epidemiological model with delay is considered. The stability of the two equilibria, existence Hopf bifurcation and permanence are investigated. It found that occurs when <TEX>${\tau}$</TEX> passes though sequence critical values. estimation length to preserve has also been calculated. Numerical simulation hypothetical set data done support analytical findings.

In this paper, a cholera epidemic model with saturated recovery rate is studied. Backward bifurcation leading to bistability possibly occurs, and global dynamics are shown by compound matrices geometric approaches. Numerical simulations presented illustrate the results. Our results suggest that basic reproduction number itself not enough describe whether will prevail or when resources for treatment of infectives limited we should pay more attention initial state cholera.

Type 2 diabetes mellitus (T2DM) has become prevalent pandemic disease in view of the modern life style. Both diabetic population and health expenses grow rapidly according to American Diabetes Association. Detecting potential onset T2DM is an essential focal point research mellitus. The intravenous glucose tolerance test (IVGTT) effective protocol determine insulin sensitivity, effectiveness, pancreatic β-cell functionality, through analysis parameter estimation a proper differential...

In this paper, the dynamical behavior of a stochastic SQEIAR epidemic model is investigated. First all, we establish sufficient conditions for extinction diseases. Then existence an ergodic stationary distribution positive solutions to are obtained by constructing suitable Lyapunov function. The implies weak stability. Furthermore, optimal control problem considered provide theoretical basis prevention and disease. Finally, results verified numerical simulations.

This study presents a class of the stochastic time-delayed susceptible–educated–infective–recovered–susceptible (SEIRS) epidemic model incorporating both public health education and Lévy jumps. We prove that system has unique global positive solution. also provide derived conditions sufficient for extinction persistence in mean. The verification findings conclusions is performed through parameter sensitivity analysis numerical simulations. concludes education, noises, vaccination, increased...
