Abstract Pedestrian flow passing through bottlenecks is complex, particularly for opposite movement in a room with single doorway. These bidirectional flows would always cause congestion and further reduce traffic efficiency so the ‘Disembarking precedes embarking’ rule widely used actual management of public spaces. However, impact imbalance pedestrian numbers on capacity throughput at bottleneck still needs exploration. Therefore, this study investigates effects ratio r pedestrians leaving...

To investigate the factors influencing severity of injuries resulting from risk-taking behaviors, comprehensive crash data Rawalpindi City spanning 2017-2021 was meticulously analyzed. This study concentrated on three potential injury outcomes: property damage only, injury, and fatality. It examined a range variables encompassing driver, vehicle, roadway, environmental, temporal, characteristics. Random parameter logit models with heterogeneity in means variances were employed to effectively...

A precise calculation that translates shifts of x-ray $K$ absorption edges to variations thermodynamic properties allows quantitative characterization interior warm dense plasmas by techniques, which provides essential information for inertial confinement fusion and other astrophysical applications. We show this interpretation can be achieved through an improved first-principles method. Our shows the shift exhibits selective sensitivity thermal parameters thus would a suitable temperature...

Objective: To analyze the current situation on infectious diarrhea other than cholera, dysentery, typhoid and paratyphoid (hereinafter referred to as Other Infectious Diarrheal Diseases) under monitoring program in China from 2014 2015, provide evidence for developing strategies related control of these diseases. Methods: All reported cases information public health emergencies relevant were collected "Chinese Information System Disease Control Prevention" . Analytic method was carried out...

High fatality rates in frequent rear-end crashes have underscored significant safety concerns China. This study aims to explore the mechanisms and determinants of crashes, with a particular focus on factors influencing crash severity during weekdays weekends (W-W). Employing Random Parameter Logit Model (RPLM) account for variability data, we analyzed W-W Beijing-Shanghai Expressway Jiangsu province from 2017 2019, considering three levels: no injury, minor severe injury. Our comprehensive...

Vibrio cholerae serogroup O139 was first identified in 1992 India and Bangladesh, association with major epidemics of cholera both countries; cases were noted shortly thereafter China. We characterized 211 V. isolates that isolated at multiple sites China between 1993 2012 from patients (n = 92) the environment 119). Among clinical isolates, 88 (95.7%) 92 toxigenic, compared 47 (39.5%) 119 environmental isolates. Toxigenic carried El Tor CTX prophage toxin-coregulated pilus A gene (tcpA), as...

Understanding the factors contributing to crash severity, along with their influence degrees across different times of day, can assist in better highway design and developing effective countermeasures for ameliorating safety (especially during nighttime). This study examines influences risk on based comparisons nighttime daytime crashes. By using a random parameter approach account unobserved heterogeneity, multivariate logit (RPML) models are proposed analyze severity explanatory terms...

It is crucial for drivers to conduct rapid and effective risk perception response processes when faced with hazardous driving situations. The low pressure oxygen environment in the plateau results a greater workload of drivers, contributing significant decline ability. This study proposes graph construction approach model drivers' hazard modes (HRMs) areas. A total 31 (23 males) aged 21 55 years (M [age] = 28.0 years, M [driving experience] 6.5 years) were recruited participate four...

This study explored the effects of contributing factors on crash frequency, by injury severity all, daytime, and nighttime crashes that occurred freeways. With three outcomes classified as light injury, minor severe explanatory variables affecting frequency were examined in terms crash, traffic, speed, geometric, sight characteristics. Regarding model estimations, lowest AIC BIC values (2263.87 2379.22, respectively) showed superiority random-parameter multivariate negative binomial (RPMNB)...
