—The location technology in wireless sensor network (WSN) is always the focus of research scholars at home and abroad. Based on an improved simulated annealing algorithm, this paper presents a novel WSN node localization algorithm. And the basic principle and the implementing approaches of the algorithm are emphatically introduced. Simulation results(More)
BACKGROUND MicroRNA (miR)-126, acting as a tumor suppressor, has been reported to inhibit the invasion of gastric cancer cells in part by targeting v-crk sarcoma virus CT10 oncogene homologue (CRK). The aim of this study was to investigate the clinical significance of miR-126/CRK axis in gastric cancer. METHODS miR-126 and CRK mRNA expression levels were(More)
Mobile Ad hoc network is a special peer-to-peer network with a wide range of application that has no infrastructure, multi-hop, self-organizing, dynamically reconfiguration and mobile. People are now paying more and more attention to the using of ad hoc network in the emergence area such as battlefield and disaster rescue. The research on its energy and(More)
A routing scheme of wireless sensor networks which is suitable for mine monitoring system is designed in this paper. Consideration of the topographic features of coal mine, two-level network is adopted. We design a semi-proactive routing protocol based on tree topology. Isolated nodes in the network send routing requests to neighbor nodes with least path(More)
