Flexible Dual-TCP/UDP Streaming Protocol with Bitstream Prioritization (FDSP-BP) is a new method for streaming H.264-encoded High-definition (HD) video over wireless networks. This paper presents a novel technique to adaptively modify the Bitstream prioritization (BP) parameter based on network conditions. This technique selects the maximum BP value that satisfies the Transmission Control Proto...
The Tibetan Plateau (TP) is primarily influenced by the northern hemispheric middle latitude Westerlies and the Indian summer monsoon (ISM). The extent, long-distance effects and potential long-term changes of these two atmospheric circulations are not yet fully understood. Here, we analyse modern airborne pollen in a transition zone of seasonally alternating dominance of the Westerlies and the...

Marek’s disease (MD) is a lymphoproliferative disease of chickens characterized by lymphocyticinfiltration of various organs. The present study was an attempt to use polymerase chain reaction (PCR) tooptimize a rapid and reliable assay for detection of MDV genome. Detection of serotype 1 of MDV (MDV-1)was confirmed by presence of a 200 bp DNA fragment as a PCR product. Differentiation of MDV-1 ...
Improving the quality of tennis teaching and learning is an important part modernization education in China. The limitations traditional evaluation methods have made them controversial, it crucial to improve scientific, rational, timely tenn quality. Therefore, necessary establish a scientific rational model for evaluate education. Based on principle constructing perfect system, this paper anal...
Purine-rich (GA)- and (GT)-containing oligophosphorothioates were investigated for their triplex-forming potential on a 23 bp DNA duplex target. In our system, GA-containing oligophosphorothioates (23mer GA-PS) were capable of triplex formation with binding affinities lower than (GA)-containing oligophosphodiesters (23mer GA-PO). The orientation of the third strand 23mers GA-PS and GA-PO was an...
Risk and security are two symmetric descriptions of the uncertainty same system. If risk early warning is carried out in time, capability system can be improved. A safety model based on fuzzy c-means clustering (FCM) back-propagation neural network was established, a genetic algorithm introduced to optimize connection weight other properties network, so as construct coal mining face. The applie...
