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...

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...

Let (X,ω, cX ) be a real symplectic 4-manifold with real part RX. Let L ⊂ RX be a smooth curve such that [L] = 0 ∈ H1(RX;Z/2Z). We construct invariants under deformation of the quadruple (X,ω, cX , L) by counting the number of real rational J-holomorphic curves which realize a given homology class d, pass through an appropriate number of points and are tangent to L. As an application, we prove ...

Anomaly detection is attractive for the analysis of hyperpectral imagery. This paper describes an expanded anomaly detection algorithm for small targets in hyperspectral imagery. As a variant of the well known multivariate anomaly detector called RX algorithm, the approach called the dimension reduction RX algorithm (DRRX) is proposed. The analytical fusion strategy is incorporated into the RX ...
