BACKGROUND Chromodomain-helicase-DNA-binding protein 5 (CHD5) is a newly identified tumor suppressor that is frequently downregulated in a variety of human cancers. Our previous work revealed that the low expression of CHD5 in colorectal cancer is correlated with CHD5 promoter CpG island hypermethylation. In this study, we investigated the effect of(More)
Relay transmission can enhance coverage and throughput, whereas it can be vulnerable to eavesdropping attacks due to the additional transmission of the source message at the relay. Thus, whether or not one should use relay transmission for secure communication is an interesting and important problem. In this paper, we consider the transmission of a(More)
In the paper, we investigate the overall outage probability (OOP) of the two-way amplify-and-forward (AF) relaying systems in an interference-limited Rayleigh fading environment. More specifically, assuming the presence of Rayleigh faded multiple interferers at the AF relay and noisy sources, an approximate closed-form expression for the OOP are derived. In(More)
Analytically studying the overall outage performance of two-way amplify-and-forward (AF) relaying systems has always been a difficult task. In this paper we study the overall outage probability (OOP) for the two-way amplify-and-forward (AF) relaying system. The channels are independent but not identically Nakagami-m fading distributed. We obtain the tight(More)
This paper studies the performance with partial relay selection in amplify-and-forward (AF) cooperative networks, where the relay node is selected depending on the instantaneous channel information of source-relay hop. The channels are independent but not identically distributed Rayleigh fading distributed. We obtain the exact outage probability expression(More)
We consider an Amplify-and-Forward relay selection for OFDM networks with fairness constraints where a source node communicates with a destination node with the help of one or more relays. The system model assumes all relays participate and considers the subcarrier pairing with fairness constraints on relays. Our subcarrier allocation algorithm is presented(More)
