Physiological effects of a gill barnacle on host blue crabs during short-term exercise and recovery

Abstract: The effects of infestation by an ectocommensal gill barnacle, Octolasmis muelleri, on the blue crab, Callinectes sapidus, were assessed by measuring respiratory and hemolymph parameters in barnacle‐infested and uninfested crabs during short‐term exercise and recovery. At rest, uninfested crabs had lower heart rates (78 beats min‐1) and ventilation rates (74 beats min‐1) than moderately infested crabs (93 beats min‐1 and 92 beats min‐1 respectively) and heavily infested crabs (104 beats min‐1 and 123 beats min‐1 respectively). During exercise and recovery these differences disappeared as all groups of crabs elevated both rates to near maximal levels. Hemolymph O2 concentrations, O2 tensions, pH and [lactate] were not different for the three groups of crabs, but, heavily infested crabs had a greater a‐v difference in Po2 than the other groups of crabs during exercise, as well as a significant a‐v difference in pH and [lactate] during exercise. The overall minimal disturbance to the crabs's hemolymph caused ...

Network Coding in Relay-Based Device-to-Device Communications

Abstract: Device-to-device (D2D) communications has been realized as an effective means to improve network throughput, reduce transmission latency, and extend cellular coverage in 5G systems. Network coding is a well established technique known for its capability to reduce the number of retransmissions. In this article, we review stateof- the-art network coding in relay-based D2D communications, in terms of application scenarios and network coding techniques. We then apply two representative network coding techniques to dual-hop D2D communications and present an efficient relay node selecting mechanism as a case study. We also outline potential future research directions, according to the current research challenges. Our intention is to provide researchers and practitioners with a comprehensive overview of the current research status in this area and hope that this article may motivate more researchers to participate in developing network coding techniques for different relay-based D2D communications scenarios.
