There has been significant progress in the development and deployment of Peer-to-Peer (P2P) live video streaming systems. However, there has been little study on the security aspect in such systems. Our prior experiences in Anysee exhibit that existing systems are largely vulnerable to intermediate attacks, in which the content pollution is a common attack(More)
In this paper, we propose a peer-to-peer live media streaming system based on application layer multicast, called Anysee, which provides efficient live media streaming service to large scale number of users. We construct the overlay data delivery tree with high locality and low maintenance overhead. The simulation results with log traces gathered from(More)
BACKGROUND This study was designed to investigate whether pretreatment of bone marrow mesenchymal stem cells (BMSCs) with 5-azacytidine (5-aza) or double intravenous infusion could enhance their therapeutic potential for dilated cardiomyopathy (DCM). MATERIAL/METHODS BMSCs were cultured for 2 weeks in the presence or absence of 5-aza and DCM serum. The(More)
Peer-to-Peer (P2P) system can support service for lots of end users with little hardware investment, which suits for the efforts to lower down the service cost for Multiplayer Online Games (MOG). In this paper, we introduce PKTown, a P2P middleware inserted into Star Craft and the network layer. PKTown captures all packets generated by Star Craft. We apply(More)
OBJECTIVE To determine the association between heart rate variability (HRV) and hypertension in Chinese children. METHODS The study was conducted in First Hospital of Jilin University, China. A total of 101 children were recruited in this study. They were divided into a high systolic blood pressure (SBP) group (HS group) and normal SBP group (NS group)(More)
