Maintaining cache consistency in mobile environment is an important issue which is extensively studied in the last decade. In mobile ad hoc networks (MANETs), a large number of nonstationary mobile terminals connecte with each other through multi-hop unreliable communication channels, coupling with the fact that disconnections from the network are very(More)

The possible different therapeutic efficacy of human mesenchymal stem cells (hMSC) derived from umbilical cord blood (CB), adipose tissue (AT) or bone marrow (BM) for the treatment of myocardial infarction (MI) remains unexplored. This study was to assess the regenerative potential of hMSC from different origins and to evaluate the role of CD105 in cardiac(More)
—Broadcast is a fundamental operation of wireless ad hoc networks (WANETs) and has widely been studied over the past few decades. However, most existing broadcasting strategies assume nonsleeping wireless nodes and thus are not suitable for uncoordinated duty-cycled WANETs, in which each node periodically switches on and off to save energy. In this paper,(More)
— Data caching on mobile clients is widely seen as an effective solution to improve system performance. In particular, cooperative caching, based on the idea of sharing and coordination of cache data among multiple users, can be particularly effective for information access in mobile ad hoc networks where mobile clients moving frequently and network(More)
—The past five years witnessed a rapid development in wireless sensor networks, which have been widely used in military and civilian applications. Due to different requirements in their application environment, sensors with different capacities, power, and so on are deployed. Data routing in such heterogeneous sensor networks is a challenging task. On one(More)
—Due to requirements in different applications, sensors with various capacities are deployed. Data routing in such heterogeneous wireless sensor networks (HWSNs) poses challenges. First, the heterogeneous features create asymmetric links in the communication graphs which are not dealt with by conventional routing algorithms using undirected graphs. Second,(More)
