The study presented in this paper investigated the possibility of using support vector machine (SVM) models for crash injury severity analysis. Based on crash data collected at 326 freeway diverge areas, a SVM model was developed for predicting the injury severity associated with individual crashes....

Traditional statistical crash prediction models oftentimes suffer from poor data quality and require large amount of historical data. In this paper, we propose a crash prediction method based on a bivariate extreme value theory (EVT) framework, considering both drivers' perception-reaction failure a...

Tin (Sn)‐based perovskites are increasingly attractive because they offer lead‐free alternatives in perovskite solar cells. However, depositing high‐quality Sn‐based perovskite films is still a challenge, particularly for low‐temperature planar heterojunction (PHJ) devices. Here, a “multichannel int...

INTRODUCTION This study aimed to investigate the contributing factors to serious casualty traffic crashes and their interdependency in China. Serious casualty crashes are defined as crashes that lead to more than 10 deaths. METHOD The data of serious casualty crashes between 2009 and 2013 were obtai...

The primary objective of this study was to evaluate the performance of traffic conflict measures for real-time crash risk prediction. Drone recordings were collected from a freeway section in Nanjing, China, over a year. Twenty rear-end crashes and their associated trajectories were obtained. Vehicl...

Gastrointestinal cancer (GIC) is the most common cancer with a poor prognosis. Currently, surgery is the main treatment for GIC. However, the high rate of postoperative recurrence leads to a low five-year survival rate. In recent years, immunotherapy has received much attention. As the only immunoth...

Ramp metering (RM) and variable speed limits (VSLs) affect freeway traffic in different ways and, accordingly, result in different effects on travel time and crash risk. This study compared the effects of RM and VSL at different freeway bottleneck segments with various traffic demands. An isolated m...

This study aims to investigate the predictability of surrogate safety measures (SSMs) for real-time crash risk prediction. We conducted a year-long drone video collection on a busy freeway in Nanjing, China, and collected 20 rear-end crashes. The predictability of SSMs was defined as the probability...

This study carried out a simulator test to determine and predict the duration of reduced driver performance during the automated driving takeover process. Vehicle trajectory and driver behavior data were collected in critical and non-critical takeover scenarios. The earth mover's distance was then a...

Purpose Genetic changes have prognostic significance in cytogenetically normal acute myeloid leukemia (CN-AML). We set out to evaluate the prognostic of 6 gene mutations in CN-AML. Methods We performed a mutational analysis and evaluated prognostic findings of six genes (NPM1, CEBPA, DNMT3A, FLT3-IT...

ABSTRACT: Integration of torque teno mini virus (TTMV) generating the TTMV::RARA (retinoic acid receptor α) fusion represents a newly recognized subtype of acute promyelocytic leukemia (APL) that merits detailed investigation. We present, to our knowledge, the first comprehensive characterization of...

Rational decision-making regarding safety-related investment programs greatly depends on the economic valuation of traffic crashes. The purpose of this study is to estimate the value of statistical life (VSL) in Hangzhou, China. A stated preference survey was conducted to investigate respondents’ wi...

This study aims to develop prediction models of driver takeover time and crash risks during the automated driving takeover process. A driving simulator experiment was conducted to collect vehicle trajectory and driver behavior data. The random-parameter duration model was first built to model driver...

BACKGROUND: An increasing number of systematic reviews (SRs) in the environmental field have been published in recent years as a result of the global concern about the health impacts of air pollution and temperature. However, no study has assessed and compared the methodological and reporting qualit...

Transit oriented development (TOD), is highly recognized as an ideal pattern for the coordinated development of urban transportation and land use, and is widely applied to solve traffic problems in large cities in China. The primary objective of this study was to evaluate the effect of TOD projects ...
