With the rapid growth of multimedia applications, Internet has been becoming crowded. IP multicast was proposed to help this situation, but not widely deployed for its scalability and fundamental network requirement problem. application-layer multicast (also called overlay multicast) is an attractive alternative solution. In this paper, we developed an(More)
BACKGROUND Raised blood pressure (BP) is associated with the incidence of metabolic syndrome (MetS). It is unknown if subjects with different BP levels may develop certain components of MetS over time. We investigated the incidence of MetS relative to different levels of BP over a 5-year period in a Chinese population in Tongren Hospital, Beijing. METHODS(More)
The relationship between liver enzymes and clustered components of metabolic syndrome (MetS) is explored and the predictive power of γ-glutamyl transferase (GGT) for the diagnosis of MetS in an adult population in Beijing is investigated. A total of 10,553 adults aged 20-65 years who underwent health examinations at Beijing Tongren Hospital in 2012 were(More)
A novel distributed video surveillance system, called as E-touch is presented in this paper. The system provides a three-layers model based on overlay network. In the middle layer of the model, overlay service network layer (OSNL) is composed of many intelligent overlay nodes mapped by underlying network. Overlay nodes provide all kinds of media service for(More)
Hybrid oysters often show heterosis in growth rate, weight, survival and adaptability to extremes of salinity. Oysters have also been used as model organisms to study the evolution of host-defense system. To gain comprehensive knowledge about various physiological processes in hybrid oysters under low salinity stress, we performed transcriptomic analysis of(More)
BACKGROUND High-density lipoprotein (HDL) is associated with the incidence of metabolic syndrome (MetS). It is unclear whether subjects with different HDL levels develop different components of MetS over time. Our study aimed to determine what MetS components tend to emerge and change relative to different levels of HDL. METHODS During the period 2007 to(More)
At present, most traditional distribution systems adopt special distribution services framework, often only for the characteristics of multimedia applications with a single provision. However, the existing framework cannot provide service guarantee for group-multimedia communication. To solve this problem, this paper designed to work on a new service(More)
