Association of atherogenic index of plasma and cardiometabolic index with all-cause mortality and cardiovascular disease in NAFLD patients: NHANES 1999–2018

Chaojie Yu, Chen Qiu, Qian Zhang, Wenrui Wang et autres

BACKGROUND: The atherogenic index of plasma (AIP) serves as a crucial indicator for assessing atherosclerotic risk. It reflects the degree of dyslipidaemia and cardiovascular disease (CVD) risk. The cardiometabolic index (CMI) provides a comprehensive evaluation of obesity-related metabolic risk, acting as a …

Optical fiber twist sensor based on a double-helix structure and quasi-distributed displacement system

Xueqian Bai, Wenrui Wang, Jun Hui Hu, Biying Zhou et autres

The inherent axial torsion of cable-type sensor arrays can cause errors in the projection direction of vector signals. Therefore, accurate characterization of torsional deformation in such arrays is of critical importance. A dual-helix optical fiber twisting measurement method was proposed for the …

Molecular Dynamics Simulation and Experimental Validation of Nanoscale Droplet Wetting and Anti-Icing Performance on OTS Self-Assembled Monolayers

Junwei Qin, Wenrui Wang, Shuming Du, B. X. Liu et autres

This study explores the performance of octadecyltrichlorosilane (OTS) self-assembled monolayer (SAM) coatings on SiO 2 substrates through molecular dynamics (MD) simulations and experimental validations.

Controlling the Scandium Gradient and Microstructure in AlN Thin Films via a Magnetron Sputtering-Ion Implantation Strategy

Xiaolu Yuan, Xueyang Bai, Kai Jyun Huang, Junjun Wei et autres

Scandium (Sc)-doped aluminum nitride (AlN) thin films are critical for high-frequency, high-power surface acoustic wave (SAW) devices. A composite Sc doping strategy for AlN thin films is proposed, which combines magnetron sputtering pre-doping with post-doping via ion implantation to achieve gradient doping …
