High quality video content for on-demand services is usually stored and streamed in a compressed format with a VBR (variable bit rate) property; however, the streaming traffic is extremely bursty. If there is no client buffer to regulate the video’s delivery, the backbone WAN (wide area network) bandwidth needs to allocate the video’s peak bit rate to guarantee playback quality. To reduce the b...

Real-time distribution of stored video over wide-area networks is a crucial component of many emerging distributed multimedia applications. The heterogeneity in the underlying network environments is an important factor that must be taken into consideration when designing an end-to-end video delivery system. In this paper, we present a novel network-conscious approach to the problem of end-to-e...

BACKGROUND Although a number of methods are used to estimate polyethylene liner wear from radiographs of total hip replacements, there is no consensus with regard to the accuracy of these methods. The purpose of this study was to compare the accuracy of several such measurement methods with use of both laboratory radiographs and routine clinical radiographs. METHODS A phantom apparatus was de...

Objective. To illustrate the difference in cold/hot natural properties and therapeutic effect of coptis-evodia herb couples by using cold/hot plate differentiating technology and microcalorimetry combined with material basis analysis in vivo and in vitro. It showed that animal retention ratio in hot pad significantly decreased along with the decrease in coptis proportion in coptis-evodia herb c...

Background: To evaluate the preventive effect and enhance immunity functions of Bu-zhong-yi-qi wan in vivo. Materials and Methods: S180 tumor mice model was established by subcutaneous injection a dose of 0.2 ml (1×10/ml) at the right oxter. The inhibitory rates, spleen indexes and thymus indexes were calculated. Splenic lymphocyte proliferative activity assay and phagocytosis activity of perit...

Due to the curse of dimensionality, solving high dimensional parabolic partial differential equations (PDEs) has been a challenging problem for decades. Recently, weak adversarial network (WAN) proposed in Zang et al. (2020) [17] offered flexible and computationally efficient approach tackle this defined on arbitrary domains by leveraging solution. WAN reformulates PDE as generative network, wh...

Software Defined WAN or better known as SDWAN has now become a technology that is hype and lot of interest, in addition to simplifying operations, it can also reduce operational costs, especially links. Researchers will make within the scope PoC Lab (Proof Concept) so later results from this show expected results, namely being able improve security connections between branches achieved by devic...

Recent work has made the case for geo-distributed analytics, where data collected and stored at multiple datacenters and edge sites world-wide is analyzed in situ to drive operational and management decisions. A key issue in such systems is ensuring low response times for analytics queries issued against geo-distributed data. A central determinant of response time is the query execution plan (Q...
