In order to solve the problem of high computational resource consumption in fabric anomaly detection, we propose a lightweight network, GH-YOLOx, which integrates ghost convolutions and hierarchical GHNetV2 backbone together to capture both local and global anomaly features. At the same time, other innovative components, such as GhostConv, dynamic convolutions, feature fusion modules, and a shared group convolution head, are applied to effectively handle multi-scale issues. Lamp pruning accelerates inference, while channel-wise knowledge distillation enhances the pruned model's accuracy.

Currently, fabric defect detection methods predominantly rely on CNN models. However, due to the inherent limitations of CNNs, such models struggle to capture long-distance dependencies in images and fail to accurately detect complex defect features. While Transformers excel at modeling long-range dependencies, their quadratic computational complexity poses significant challenges.

The understanding of toxicological and pharmacological profiles of nanomaterials is an important step for the development and clinical application of nanomedicines. Carbon nanotubes (CNTs) have been extensively explored as a nanomedicine agent in pharmaceutical/biomedical applications, such as drug delivery, bioimaging, and tissue engineering. The biological durability of CNTs could affect the function of CNTs-based nanomedicines as well as their toxicity in cells and tissues.

Gene expression profile GSE34516 was downloaded from the Gene Expression Omnibus. Eight locus coeruleus post-mortem tissue samples derived from four IPD patients and four neurological healthy controls were used to identify the differentially expressed genes (DEGs) by paired t test.

Polymers from renewable biomass are viable supplements for synthetic polymers. In this study, cellulose nanocrystals (CNs) were used as nanofillers to improve properties of rosin-based waterborne polyurethanes (RWPU). The morphology, structure, thermal, and mechanical properties of the RWPU/CNs nanocomposites were investigated.

Objective: To investigate the protective effect of puerarin on the myocardium of rats with acute and chronic alcoholism.
Methods: In acute alcoholism experiment, normal male SD rats were randomly divided into the control group, alcoholism group and puerarin group (n=8), and high- and low-dose puerarin was administered. In chronic alcoholism experiment, increasing puerarin doses were given.
