—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)
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)
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)
