PURPOSE Retinal circadian signals may have a role in maintaining the normal function and health of photoreceptors. Melatonin is an output of the retinal circadian oscillator and provides nocturnal signaling that is mediated through specific G-protein-coupled receptors. Melatonin receptors are expressed in retinal photoreceptor cells, and this study was undertaken to test the hypothesis that mel...

In this paper, we show how to construct exceptional orthogonal polynomials (XOP) using isospectral deformations of classical polynomials. The construction is based on confluent Darboux transformations, where repeated factorizations at the same eigenvalue are allowed. These allow us Sturm–Liouville problems with polynomial eigenfunctions that have an arbitrary number real-valued parameters. We i...

We consider the zeros of exceptional orthogonal polynomials (XOP). Exceptional were originally discovered as eigenfunctions second order differential operators that exist outside classical Bochner–Brenke classification due to fact XOP sequences omit certain degrees. This omission causes several properties polynomial not extend sequences. One such property is restriction convex hull support meas...

Xanthomonasoryzae pv. oryzae (Xoo) is spread systemically through the xylem tissue and causes bacterial blight in rice. We evaluated the roles of Xanthomonas outer proteins (Xop) in the Xoo strain KXO85 in a Japonica-type rice cultivar, Dongjin. Five xop gene knockout mutants (xopQ KXO85 , xopX KXO85 , xopP1 KXO85 , xopP2 KXO85 , and xopN KXO85 ) were generated by EZ-Tn5 mutagenesis, and their ...

The selective advantage of an allele Gi (relative to the mean of alleles at this locus) is given by (formula: see text) in which Ai is the average excess of the allele on the character, X; W(X) is the fitness function; F(X) is the frequency function; W is the mean fitness; and the prime denotes differentiation. With truncation selection si = AaF(C)/w in which F(C) is the ordinate at the culling...

In 2013 Intel will release the AVX2 instructions, which introduce 256-bit singleinstruction multiple-data (SIMD) integer arithmetic. This will enable desktop and server processors from this vendor to support 4-way SIMD computation of 64-bit add-rotate-xor algorithms, as well as 8-way 32-bit SIMD computations. AVX2 also includes interesting instructions for cryptographic functions, like any-to-a...

Spectromicroscopy (SM) beamline is planned to be one of the day one beamlines of the Iranian Light Source Facility project (ILSF) to open high impact research investigations in the field of soft x-ray spectroscopy and microscopy for the Iranian and regional users. This beamline offers the possibility of performing photoelectron emission microscopy (PEEM) and scanning photoelectron microscopy (S...
