Video sharing has been an increasingly popular application in online social networks (OSNs). However, its sustainable development is severely hindered by the intrinsic limit of the client/server architecture deployed in current OSN video systems, which is not only costly in terms of server bandwidth and storage but also not scalable with the soaring amount of users and video content . The peer-...

To understand the size of the aging population in the United States, the imminent need to include the elderly in clinical studies on lung cancer, and the safe potential of video-assisted thoracic surgery, and to change awareness of the elderly's need for and ability to undergo treatment for lung cancer, clinical studies of video-assisted thoracic surgery in patients > or = 70 years of age are p...

Thymoma has malignant potential and is the most common anterior mediastinal tumor. Video-assisted thoracic surgery (VATS), which is less invasive surgical procedure, is a good option for resecting Masaoka stage I tumors. Whether VATS is appropriate, depends on the surgeon's judgment and accurate imaging diagnosis. We introduce a technique involving a combination of video-assisted thoracoscopic ...

We present a dedicated video-based monitoring system for quantification of patient’s attention to visual feedback during robot assisted gait rehabilitation. Two different approaches for eye gaze and head pose tracking are tested and compared. Several metrics for assessment of patient’s attention are also presented. Experimental results with healthy volunteers demonstrate that unobtrusive video-...

Bronchogenic cysts are congenital lesions from the primitive foregut, mostly located in the mediastinum. Surgical excision in symptomatic cases is often challenging. Video-assisted mediastinoscopy offers a safe and effective approach with less morbidity and shorter hospital stay compared to open sternotomy or posterolateral thoracotomy. We describe a case of a young female with a large symptoma...

Video-assisted thoracoscopic treatment of intralobar pulmonary sequestration in an obese (120 kg, body mass index 42) young man is described. Two aberrant arteries originating from the descending thoracic aorta were transected with a vascular stapler, and a left lower lobectomy was successfully performed thoracoscopically. Three-dimensional chest computed tomography was used to identify the abe...
