Abstract Three‐dimensional (3D) woven textile‐reinforced composites have drawn much attention because of their specific geometries, improved composite interlayer strength, and impact‐resistance performance. In this study, three types 3D structures with different binder‐yarn ratios paths were designed based on a traditional dobby‐weaving loom special weft‐interlock structural design. Carbon/aramid fiber‐reinforced plastic (CAFRP) carbon warp, weft, aramid binder yarns, as well (CFRP)...

The study of energy evolution laws has been widely applied in the geotechnical analysis soft rocks and coal seams. However, research on marine soil primarily focused consolidation behavior, shear properties, microstructural evolution, with limited exploration systematic methods based laws. This paper addresses this gap by analyzing dynamic triaxial test data to explore relationship between loss rate number cyclic loadings soil. Through calculations derivations, a mathematical expression for...

<title>Abstract</title> Endometrial hyperplasia (EH) is a common disease within the realm of gynecological endocrinology and considered precancerous lesion. The aim this study to identify assess most prevalent drugs associated with risks EH by using real-world data. Adverse drug events (ADEs) related were retrieved from FAERS database (FAERS, Q1/2004-Q3/2024). A disproportionality analysis was conducted that have significant connection EH. In study, 601 ADEs endometrial identified. Among...
