The paired-like homeobox-containing gene Rx has a critical role in the eye development of several vertebrate species including Xenopus, mouse, chicken, medaka, zebrafish and human. Rx is initially expressed in the anterior neural region of developing embryos, and later in the retina and ventral hypothalamus. Abnormal regulation or function of Rx results in severe abnormalities of eye formation....

Rx is a paired-like homeobox gene that is required for vertebrate eye formation. Mice lacking Rx function do not develop eyes or the posterior pituitary. To determine whether Rx is required cell autonomously in these tissues, we generated embryonic chimeras consisting of wild type and Rx-/- cells. We found that in the eye, Rx-deficient cells cannot participate in the formation of the neuroretin...

This paper presents an 11-15GHz MMIC multifunction chip (MFC) with phase and amplitude control. The is based on the common-leg structure comprises a shifter (PS), attenuator (ATT), T/R switch, gain compensation amplifiers (AMPs), driver stage AMPs parallel control circuits. In bandwidth, measurements show that saturation power (Psat) are higher than 21.5dB 26.5dBm, while efficiency more 30% in ...

This article elaborates on an accurate energy model (EM) for wireless sensor devices (WSDs) based power consumption measurement. A deep understanding of WSD’s cost depends the functional components contributing to communication process. The includes different stages transmission (Tx) and reception (Rx) modes. practical EM is developed with data packet lengths, rate, operation status, predesigne...

We describe the activities of RX-P763, RX-P766, RX-P770, RX-P792, RX-P793, and RX-P808 against strains of resistant Pseudomonas aeruginosa. These compounds target the large subunit of the bacterial ribosome and have broad-spectrum activities against multidrug-resistant pathogens. All compounds demonstrated in vitro activity against P. aeruginosa, with MIC(90) values of 4 to 8 μg/ml (range, 0.5 ...

It has been proposed that RX J1914.4+2456 is a stellar binary system with an orbital period of 9.5 mins. As such it shares many similar properties with RX J0806.3+1527 (5.4 mins). However, while the X-ray spectrum of RX J0806.3+1527 can be modelled using a simple absorbed blackbody, the X-ray spectrum of RX J1914.4+2456 has proved difficult to fit using a physically plausible model. In this pap...

The Drosophila mushroom bodies, centers of olfactory learning and memory in the fly 'forebrain', develop from a set of neural stem cells (neuroblasts) that generate a large number of Kenyon cells (KCs) during sustained cell divisions from embryonic to late pupal stage. We show that retinal homeobox (rx), encoding for an evolutionarily conserved transcription factor, is required for proper devel...

Rotational-XOR (RX) cryptanalysis is a cryptanalytic method aimed at finding distinguishable statistical properties in Addition-Rotation-XOR-C ciphers, that is, ciphers can be described only by using modular addition, cyclic rotation, XOR and the injection of constants. In this study, we extend RX-cryptanalysis to AND-RX similar design paradigm where addition replaced vectorial bitwise AND; suc...

The Rx locus in potato controls extreme resistance to most isolates of potato virus X (PVX). The resistance is expressed in whole plants and in protoplasts. Rx-mediated resistance in protoplasts causes reduced accumulation of all PVX RNA species, including the (-) strand RNA after a lag of 8 hr postinoculation. In work reported elsewhere, we have shown that the Rx-breaking property of PVXHB was...
