From Global to Local: Multi-Patch and Multi-Scale Contrastive Similarity Learning for Unsupervised Defocus Blur Detection.

Defocus blur detection (DBD), which aims to detect out-of-focus or in-focus pixels from a single image, has been widely applied to many vision tasks. To remove the limitation on the abundant pixel-level manual annotations, unsupervised DBD has attracted much attention in recent years. In this paper, a novel deep network named Multi-patch and Multi-scale Contrastive Similarity (M2CS) learning is proposed for unsupervised DBD.

Zhoubo plus uncaria tincture in the treatment of cerebral concussion sequelae.

[Purpose] This study investigated the clinical efficacy of the compound gouteng tincture combined with Zhoubo (GT-ZB) in treating the sequelae of cerebral concussion (CC) in children. [Subjects and Methods] Sixty children with CC-sequelae were randomily divided into a treatment group and a control group, with 30 cases in each group. The treatment group was treated using GT-ZB, and the control group was treated using the standard method of venoruton, dibazol, and Vitamin B6.
