Detecting small objects in aerial images captured by unmanned vehicles (UAVs) is challenging due to their complex backgrounds and the presence of densely arranged yet sparsely distributed targets. In this paper, we propose a real-time object detection algorithm called YOLOv7-UAV, which specifically designed for UAV-captured images. Our approach builds upon YOLOv7 introduces several improvements: (i) removal second downsampling layer deepest head reduce model’s receptive field preserve...
Soft tissue injuries (STIs) are the most common cause of extremity pain and motion dysfunction. Persistent inflammatory activation immune cells characterized by senescence‐associated secretory phenotype (SASP) mitochondrial stress considered primary causes STIs, a pathological process also termed inflammaging.
