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)
In this paper, a service architecture based on overlay network was presented. The architecture was designed to build a novel distributed video surveillance system, called as E-touch. In the model, the system is divided into three layers: underlying network layer (UNL) , overlay service network layer (OSNL) and application layer (AL). OSNL is composed of(More)
Ao shi shang han jin jing lu (Ao's Records of Golden Mirror on Cold Pathogenic Diseases) is the extant first work of lingual diagnosis. It is demonstrated that the author of this book is categorized under the school of Liu Wansu based on the location of disease, the nature of disease, therapies and drugs, and pathogenesis in pathological lingual pictures(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)
In this paper, we present a two-layer overlay multicast framework for building an application-layer multicast(ALM) system model. The framework employs an optimal unicast path selection (OUPS) algorithm, which can select QoS-satisfied multicast tree path for stream applications. This algorithm is proposed to compute the QoS weight values of paths in overlay(More)
