A crash prediction method based on bivariate extreme value theory and video-based vehicle trajectory data

Verified

Chen Wang, Chengcheng Xu, Yulu Dai

Journal: Accident Analysis & PreventionYear: 2018Citations: 202

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...

Overexpression of ACE2 Enhances Plaque Stability in a Rabbit Model of Atherosclerosis

Verified

Bo Dong, Cheng Zhang, Jing Bo Feng, Yu Zhao et al.

Journal: Arteriosclerosis Thrombosis and Vascular BiologyYear: 2008Citations: 129

OBJECTIVE: The purpose of this study was to test the hypothesis that ACE2 overexpression may enhance atherosclerotic plaque stability by antagonizing ACE activity and converting angiotensin II to angiotensin 1-7. METHODS AND RESULTS: Atherosclerotic plaques were induced in the abdominal aorta of 114...

Unsaturated bond recognition leads to biased signal in a fatty acid receptor

Verified

Chunyou Mao, Peng Xiao, Xiao-Na Tao, Jiao Qin et al.

Journal: ScienceYear: 2023Citations: 124

Individual free fatty acids (FAs) play important roles in metabolic homeostasis, many through engagement with more than 40G protein–coupled receptors. Searching for receptors to sense beneficial omega-3 FAs of fish oil enabled the identification of GPR120, which is involved in a spectrum of metaboli...
