Background: The role of cystathionine γ-lyase (CTH) in the prognosis and immune invasion of hepatocellular carcinoma (HCC) remains poorly understood. Methods: In this study, the clinical data of patients with HCC were analyzed, and the expression le

A wireless ad hoc network is a self-organized wireless network without centralized infrastructure. In such a network, nodes rely on each other to forward packets to remote destinations. A threat to such multihop transmission is posed by selfish nodes

Dynamic spectrum access has been studied to exploit instantaneous spectrum availability by opening licensed spectrum to secondary users. To achieve high spectrum efficiency, secondary unlicensed users need to continuously sense spectrum to detect the

In ad hoc networks, wireless nodes rely on each other to transmit data over multi-hops by forwarding packets. A selfish node may decide not to forward packets for other nodes to save its own resource but still use the network to send and receive data

Cellular networks serve a huge amount of users but their allocated spectrum is very limited. Cognitive Radio is a potential technique to make use of underutilized bands to provide more spectrum resource to cellular network. However to make them work

To solve the scarcity of wireless spectrum, Cognitive Radio (CR) is proposed to let unlicensed wireless users (secondary users) dynamically find and access unused channels without interference to licensed users (primary users). The performance of the

Accurate spectrum sensing is one of the key technologies to enable dynamic spectrum access in cognitive radio networks. Recently cooperative spectrum sensing is proposed as an efficient way to achieve better sensing accuracy. It makes use of multiple

Reputation based and credit-exchange based approaches have been studied extensively to enforce cooperation among non-cooperative nodes in wireless ad hoc networks. Most of the existing solutions are fundamentally context-based ones, which need to acc
