DUPLEX PERSONALITY

Full-Duplex Relaying with Half-Duplex Relays

We consider “virtual” full-duplex relaying by means of half-duplex relays. In this configuration, each relay stage in a multi-hop relaying network is formed by at least two relays, used alternatively in transmit and receive modes, such that while one relay transmits its signal to the next stage, the other relay receives a signal from the previous stage. With such a pipelined scheme, the source ...

Duplex DNA

This article describes the sequence-specific isolation and purification of intact double-stranded DNA (dsDNA) by oligonucleotide/PNA-assisted affinity capture (OPAC). The OPAC assay is based on selective tagging of a DNA duplex by biotinylated oligodeoxyribonucleotide (ODN) through formation of a so-called PD-loop. The PD-loop is assembled with the aid of a pair of PNA “openers”, which allow se...

Appendix Vermiformis Duplex.

Duplication of the alimentary tract is uncommon but duplication of the appendix is rare. Basu et al. (1959), in reporting 28 cases of duplication of the alimentary tract, had no case of appendix duplex. Picoli ( 1892) reported the first case of apendix duplex in a female patient who had associated anomalies of duplication of the entire large bowel, two uteri with two vaginae, ectopia vesicae an...

Duplex Stability & Nuclease Resistance

Full-Duplex WiFi Networks

The device in conventional half-duplex WiFi networks cannot perform carrier sensing while in data transmission; thus it suffers from long collision duration. To mitigate this problem, this chapter introduces full-duplex (FD) technology into WiFi networks. A novel CSMA/CD protocol design is first presented for singlechannel FD-WiFi, which facilitates continuous carrier sensing and transmission s...
