For preventing the leakage of confidential messages sent to a marcocell user in dense heterogeneous networks, a physical layer security scheme based on base station cooperation is proposed in the paper. To improve transmission rate of confidential messages and make the downlink signals of other legitimate users interfere with eavesdroppers, the beamforming vectors at a macrocell base station and femtocell...
This paper implements a remote control method based on B/S model. That is to create a Web server — Boa in the ARM's hardware platform and to develop a CGI form processing program based on the Boa. Finally we achieve dynamic Web interactive function between the PC and the target Board.
Ischemia/reperfusion (I/R) injury mainly caused by oxidative stress plays a major role in cardiac damage. The extent of the I/R injury is also an important factor that determines the function of a transplanted heart. This study first examined whether hemoglobin-based oxygen carriers (HBOCs) could protect isolated rat heart from I/R injury and then elucidated the underlying mechanism. Using the Langendorff...
