Non-HDL-C to HDL-C ratio and risks of all-cause and cardiovascular mortality in patients with coronary heart disease and type 2 diabetes mellitus

Dyslipidemia is a major contributor to adverse outcomes in patients with coronary heart disease (CHD) and type 2 diabetes mellitus (T2DM). The non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) is a comprehensive lipid marker, but its pr...

Numerical Investigation of Mixed Mode I-III Fracture Behavior in Sandstone Under Static and Dynamic Loading

Mixed mode I–III fracture commonly occurs in rock masses under complex three-dimensional stress states, yet the combined effects of loading conditions and fracture mode remain unclear. In this study, a heterogeneous sandstone disc model is developed in ABAQUS by coupling the Druc...
