—Cooperative diversity is an effective technique for transmission performance improvement over fading channels. In this paper, through the use of a virtual antenna array, a time division multiple access (TDMA) based cooperative media access control (MAC) protocol, Cooperative TDMA (C-TDMA), is proposed to enable cooperative transmissions in Rayleigh fading(More)
—To enable secondary transmissions in cognitive radio (CR) networks, the medium access control (MAC) protocol design for CR networks is an important but challenging issue. In this paper, we propose a cognitive packet reservation multiple access (Cog-PRMA) protocol for the CR/secondary users (SUs) sharing a common channel with time division multiple access(More)
Grids can integrate the distributed resources on the Web such as computing, data, storage, software and manpower to accomplish collaborative tasks. Service grid has combined Web service with the grid, and over the next decade lots of business will be completely transformed by using grid-enabled Web services to share not only applications but also computer(More)
Despite recent advances in the management of non-small cell lung cancer (NSCLC), the prognosis of NSCLC is still relatively poor. Thus, it is of great importance to identify novel effective diagnostic and prognostic biomarker of NSCLC. A growing volume of literature has demonstrated the vital roles of long non-coding RNAs (lncRNAs) in cancer biology.(More)
Recent advances in wireless network and the mobile computing devices are affecting how software deployment is being performed. Therefore, to the component-based applications, the deployment of the components should be suited to the user needs, the resources of the terminal and the surrounding environment. Usually we use the component-based middleware to(More)
With the rapid development of computer simulation technology, the Radar simulation applications scale up increasingly. More and more Radar simulation applications adopt distributed structure to improve system performance and availability. Hence, how to enhance the robustness and efficiency of these complex distributed simulation systems is a hot point. We(More)
We described previously a screening protocol in Drosophila melanogaster that allows us to identify small molecules that increase the killing effect of ionizing radiation in vivo in a multicellular context. The ability of this screen to identify agents that enhance the effect of radiation in human cancer models has been validated in published(More)
BACKGROUND Accumulating evidence suggests that dysregulated snoRNA may play a role in the development of malignancy. In the present study, we investigated the role of SNORD78 in the tumorigenesis of non-small cell lung cancer (NSCLC). METHODS We determined the expression level of SNORD78 in NSCLC tissues with quantitative real-time PCR and then studied(More)
