in this paper, we present the numerical solution of ordinary di erential equations (or sdes), from each order especially second-order with time-varying and gaussian random coecients. we indicate a complete analysis for second-order equations in special case of scalar linear second-order equations (damped harmonic oscillators with additive or multi- plicative noises). making stochastic di erent...

microdeletion syndromes are contiguous gene deletion syndromes of less than 5 megabases.  most often, many of these syndromes are not detectable by  routine chromosomal analysis and require more specific testing techniques such as fish or more accurate general coverage like array comparative genomic hybridization.  as many of these syndromes are phenotypically recognizable and allow for easy cl...

We perform a comprehensive theoretical and experimental analysis of the use of all-diierent constraints. We prove that generalized arc-consistency on such constraints lies between neighborhood inverse consistency and, under a simple restriction, path inverse consistency on the binary representation of the problem. By generalizing the arguments of Kondrak and van Beek, we prove that a search alg...

in this paper, a new and ecient approach is applied for numerical approximationof the linear di erential equations with variable coecients based on operational matriceswith respect to hermite polynomials. explicit formulae which express the hermite expansioncoecients for the moments of derivatives of any di erentiable function in terms of theoriginal expansion coecients of the function itse...

a new facile route for synthesis of 3- (aryl) -8, 9- di (alkyl) thieno [3,2-e] [1,2,4] triazolo pyrimidines derivative from the same starting material, 2- amino - 4,5 -di (alkyl) thiophene-3- carboxamide, has been developed through heterocyclization of the corresponding arylidene-hydrazino -5,6 -di (alkyl) thieno [2,3-d] pyrimidine under refluxing condition with acetic anhydride followed by air...

The paper discusses the expanding scope of the aid-for-trade agenda, the amount of ODA donors are providing in support of trade, the prospects for additional resources, the problems related to identifying market failures, the principles for aid effectiveness, and the main areas for improving the effectiveness of aid-for-trade. It also elaborates a proposal to create aid-for-trade partnerships b...

A new, low band-gap donor-acceptor-type conjugated polymer, PDPP-PER, comprising 3,9-perylene (PER) and diketopyrrolo[3,4-c]pyrrole (DPP) was synthesized. The crystallinity of the synthesized polymer film significantly improved with thermal annealing to 150 °C. The PCE of the PDPP-PER device reached 6.35% with a high open-circuit voltage of 0.79 V.

Programme. However, the findings, interpretations and conclusions expressed in this paper are entirely those of the authors, and should not be attributed to ODA, which does not guarantee their accuracy and can accept no responsibility for any consequence of their use. i Preface This literature review has been prepared as part of a study looking at the financing of agricultural research and exte...

In this paper we focus on the relationship between remittance inflows and financial inclusion in developing countries. We present single equation estimates on remittances and financial inclusion, and system estimates in which economic growth is explained by e.g., financial inclusion, and financial inclusion by, e.g., remittances inflows. These regressions clearly confirm our main hypothesis tha...
