For many applications in wireless sensor network (WSN), the gathering of the holistic sensor measurements is difficult due to stringent constraint on network resources, frequent link, indeterminate variations in sensor readings, and node failures. As such, sensory data extraction and prediction technique emerge to exploit the spatio-temporal correlation of(More)
Esophageal squamous cell carcinomas (ESCC) have become a severe threat to health and the current treatments for ESCC are frequently not effective. Recent epidemiological studies suggest that the anti-hyperglycemic agent metformin may reduce the risk of developing cancer, including ESCC, among diabetic patients. However, the antitumor effects of metformin on(More)
Data compression ideas can be extended to assess the data quality across multiple sensors to manage the network of sensors to optimize the location accuracy subject to communication constraints. From an unconstrained-resources viewpoint it is desirable to use the complete set of deployed sensors; however, that generally results in an excessive data volume.(More)
—In mobile ad hoc networks (MANETs), node mobility causes network topologies to change dynamically over time, which complicated important tasks such as routing. The previous stability-oriented routing algorithms usually focus on how to discover a stable route, but rarely consider the adaptability of constructed route to the change of node's motion. In this(More)
OBJECTIVE To investigate acute recoil of bioabsorbable poly-L-lactic acid (PLLA) stent. BACKGROUND As newly developed coronary stent, bioabsorbable PLLA stent still encountered concern of acute stent recoil. METHODS Sixteen minipigs were enrolled in our study. Eight PLLA XINSORB stents (Weite Biotechnology Co., Ltd., China) and eight metallic stents(More)
