Effects of polymer lubricants with different chemical polarity on the performance of SBS-modified asphalt

Zhen Zhang, Xiaoguang Zheng, Yajie Chen, Xuelei Gao et autres

The application of warm-mix technologies in Styrene-Butadiene-Styrene (SBS) modified asphalt is currently hindered by high viscosity and the resulting high energy consumption during production. To address these limitations, this study evaluates the efficacy of five polymer lubricants with varying chemical polarities—polyolefin, polyethylene, …

A study on the trajectory of depression in Chinese middle-aged and elderly patients with cardiometabolic comorbidities: based on a group trajectory model

Li Yueren, Geng Yadong, Liu Honglin, Guo Shuanglei et autres

Research indicates that cardiovascular metabolic comorbidity (CMM) is an important risk factor for depression in middle-aged and older adults. However, the relationship between depression trajectories and CMM remains unclear. This study analyzed data from the China Health and Retirement Longitudinal Study (CHARLS) …

Base-promoted dearomatization/1,6-addition of α-haloketones: synthesis of α-azido-α,α-diaryl ketones

Ze-Yu Su, Bo Lu, Yi‐Rui Zhang, Jun-Hui Luo et autres

We report an unprecedented tandem process involving a dearomatization/1,6-conjugate addition sequence that enables the α-azidation of ketones. This transformation operates at room temperature, exhibits excellent chemo- and regioselectivity, and requires no external oxidants or metal catalysts.

Simulations of Structured Upflows from Plumes and Their Connection to the Solar Wind

K. Bora, L. P. Chitta, Yajie Chen, Damien Przybylski et autres

Abstract Small-scale transient jetlet activity and associated upflows from coronal hole plumes are potential sources of the solar wind. To elucidate the magnetic origins and driving mechanisms of such upflows, we perform three-dimensional (3D) radiative magnetohydrodynamic simulations using the MURaM code, spanning …

EVA-X: a foundation model for general chest x-ray analysis with self-supervised learning

Jingfeng Yao, Xinggang Wang, Yuehao Song, Huangxuan Zhao et autres

Artificial intelligence analysis methods for chest X-ray images are limited by insufficient annotation data and varying levels of annotation, resulting in weak generalization ability and difficulty in clinical dissemination. Here, we present EVA-X, an innovative foundational model based on X-ray images with …

High‐Performance 3 µm‐Thick Bifacial All‐Inorganic Perovskite Photovoltaics with Fick‐Diffusion‐Engineered Linearly Graded Junction

Mengyao Liu, Peng Gao, Xuanchen Xu, Zongwei Chen et autres

Abstract Bifacial perovskite solar cells present a promising strategy to enhance power output by capturing light from both sides. A micrometer‐thick perovskite film is highly desired for extending the light absorption path under bifacial illumination conditions, thereby improving overall efficiency. However, this …
