Exceptional orthogonal polynomial systems (X-OPS) arise as eigenfunctions of Sturm-Liouville problems and generalize in this sense the classical families of Hermite, Laguerre and Jacobi. They also generalize the family of CPRS orthogonal polynomials introduced by Cariñena et al., [3]. We formulate the following conjecture: every exceptional orthogonal polynomial system is related to a classical...

A chemical receptor specific to traces of organophosphorus nerve agents (OPs) has been synthesized and grafted to carbon nanotubes and silicon nanowires in order to make electrical sensors. Our results show that it is possible to detect efficiently sub-ppm traces of OPs with excellent selectivity notably with the use of silicon nanowires by monitoring the Drain-Source current of the SiNW-FET at...

In this paper we report the development and validation of a compressible solver with shock capturing, using a domain-specific high-level abstraction framework, OPS, that is being developed at the University of Oxford. OPS uses an active library approach for block-structured meshes, capable of generating codes for a variety of parallel implementations with different parallelization strategies. P...

Blackberry is a highly perishable fruit and its quality decreases very quickly during postharvest period. In this research, two types of container including: oriented poly styrene (OPS), a petroleum-based material, and oriented poly corn starch (OPCS), a bio-based material, was analyzed over 14 days to determine their effects on shelf life of thornless blackberry. Packages were placed in freeze...

Oligodendrocyte maturation has been defined based on expression of developmentally regulated antigens. However, transitions at early stages of the lineage have not been functionally characterized fully in situ. Combining 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP)-promoter driven enhanced green fluorescent protein expression and whole-cell capacitance measurements permitted a reliable di...

Agricultural cooperatives around the world are facing major structural challenges as they respond to a more industrialized agriculture, globalization, and freer trade. Co-ops are responding to these changes by merging, by finding new ways of raising capital, and by developing new organizational forms such as New Generation Co-ops. One of the critically important issues co-ops face as they under...

The molecular mechanisms by which vascular tissues acquire their identities are largely unknown. Here, we report on the identification and characterization of VASCULATURE COMPLEXITY AND CONNECTIVITY (VCC), a member of a 15-member, plant-specific gene family in Arabidopsis (Arabidopsis thaliana) that encodes proteins of unknown function with four predicted transmembrane domains. Homozygous vcc m...

Since the rapid increase in atmospheric methane was recognized in the early 1980’s, paddy fields have been considered to be one of the likely and most important sources of this problem. The objective of this study is to estimate the methane emission from paddy fields with remotely sensed data and the methane flux in situ. In this paper, firstly, we developed a scaling technique to extrapolate t...

We show that, if U is the representation of SOe(n+1, 1) on L2(Sn) given by (2.11), and P is a bounded operator on L2(Sn), then P belongs to OPS0 1,0(S n) if and only if P (g) = U(g)PU(g)−1 is a C∞ function on SOe(n+1, 1) with values in the Banach space L(L2(Sn)). Introduction Let M be a compact C∞ manifold. Denote by OPS 1,0(M) the space of pseudodifferential operators on M , whose symbols in l...
