A ViSAR Shadow-Detection Algorithm Based on LRSD Combined Trajectory Region Extraction
Remote Sensing, 2023 Shadow detection is a new method for video synthetic aperture radar moving target indication (ViSAR-GMTI). The shadow formed by the target occlusion will reflect its real position, preventing the defocusing or offset of the moving target from making it ...

Concurrent Long Thoracic and Lateral Cutaneous Intercostal Nerve Entrapment After Chest Tube Thoracostomy Causing Scapular Winging and Chest Wall Pain: Diagnosis With Ultrasound and Treatment With Hydrodissection. [PDF]
Pain PractABSTRACT Background Chest tube thoracostomy may cause iatrogenic nerve injury, resulting in persistent pain and functional impairment. Long thoracic nerve (LTN) palsy after chest tube placement has been described, but concurrent involvement of the LTN and the lateral cutaneous branch of an intercostal nerve (LCIN) appears to be rarely reported.
