A cooperative full duplex (FD) nonorthogonal multiple access (NOMA) scheme over Rician fading channels is considered. The practical, imperfect successive interference cancellation and residual hardware impairments at transceivers are taken into account. To evaluate the performance of considered system, analytical approximate expressions for outage probability ergodic rate system derived, asympt...

A 4 ns molecular dynamics simulation of an RNA duplex (r-GGACUUCGGUCC)(2 )in solution with Na+ and Cl- as counterions was performed. The X-ray structure of this duplex includes two water-mediated uracil-cytosine pairs. In contrast to the other base-pairs in the duplex the water-mediated pairs switch between different conformations. One conformation corresponds to the geometry of the water-media...

TiN/SiOx duplex coatings were synthesized on AISI304 stainless steel by plasma immersion ion implantation and deposition (PIIID) followed by radio frequency magnetron sputtering (RFMS). The microstructure and tribocorrosion failure behaviors of the duplex coatings were investigated by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, atomic force microscopy, rec...

Using duplex DNA-AuNP aggregates, a sequence-specific DNA-binding protein, SQUAMOSA Promoter-binding-Like protein 12 (SPL-12), was directly determined by SPL-12-duplex DNA interaction-based colorimetric actions of DNA-Au assemblies. In order to prepare duplex DNA-Au aggregates, thiol-modified DNA 1 and DNA 2 were attached onto the surface of AuNPs, respectively, by the salt-aging method and the...

The Rap protein of phage lambda is an endonuclease that nicks branched DNA structures. It has been proposed that Rap can nick D-loops formed during phage recombination to generate splice products without the need for the formation of a 4-strand (Holliday) junction. The structure specificity of Rap was investigated using a variety of branched DNA molecules made by annealing partially complementa...

The kinetics for the binding of cisplatin to duplex RNAs, two fully complementary model systems and mature miR-146a, exhibits a linear dependence on cisplatin concentration and results in duplex dissociation at 38 °C.

Fragile X Mental Retardation Protein (FMRP) is a regulatory RNA binding protein that plays a central role in the development of several human disorders including Fragile X Syndrome (FXS) and autism. FMRP uses an arginine-glycine-rich (RGG) motif for specific interactions with guanine (G)-quadruplexes, mRNA elements implicated in the disease-associated regulation of specific mRNAs. Here we repor...

The residence time of the bound water molecules in the antisense oligodeoxyribonucleotides containing 7'-alpha-methyl (TMe) carbocyclic thymidines in duplex (I), d5'(1C2G3C4G5A6A7TMc8TMe9C10G11C12G)23', and 6'-alpha-hydroxy (TOH) carbocyclic thymidines in duplex (II), d5'(1C2G3C4G5AOH6AOH7TOH8 TOH9C10G11C12G)2(3), have been investigated using a combination of NOESY and ROESY experiments. Becaus...

BACKGROUND AND PURPOSE Contrast-enhanced MR angiography and extracranial color-coded duplex sonography are noninvasive, preoperative imaging modalities for evaluation of carotid artery stenosis. Innovative techniques and improvements in image quality require frequent reassessment of accuracy, reliability, and diagnostic value compared with those of digital subtraction angiography (DSA). We eval...

BACKGROUND The purpose of this study was to assess the benefits of duplex compared with clinical vein graft surveillance in terms of amputation rates, quality of life, and healthcare costs in patients after femoropopliteal and femorocrural vein bypass grafts. METHODS AND RESULTS This was a multicenter, prospective, randomized, controlled trial. A total of 594 patients with a patent vein graft...
