Energy-Efficient SWIPT-Empowered D2D Mode Selection.

While mode selection has been envisioned as the most cost-effective way to address the interference issue in Device-to-Device (D2D) communications, existing works have been largely conducted without consideration of the energy depletion of devices. In this paper we investigate simultaneous wireless information and power transfer (SWIPT) empowered mode selection based on stochastic geometry. As a mean of solving it, system energy efficiency is formulated by determining the closed-form ergodic energy-harvested and ergodic capacity of D2D and cellular users in reuse, dedicated, and cellular communication modes with the time switching and power splitting architectures of SWIPT.

Network Coding in Relay-based Device-to-Device Communications.

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 state-of-the-art network coding in relay-based D2D communications, in terms of application scenarios and network coding techniques.

[Comparison of Cj1136, Cj1138 and Cj1139 genes among Campylobacter jejuni strains].

Objective: By sequenceing the Cj1136, Cj1138 and Cj1139 gene of Campylobacter jejuni (C. jejuni) strains associated with Guillain-Barré Syndrome (GBS), features of Cj1136, Cj1138 and Cj1139 gene were studied. Results were compared with the C.
