To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...

For the unitary ensembles of N × N Hermitian matrices associated with a weight function w there is a kernel, expressible in terms of the polynomials orthogonal with respect to the weight function, which plays an important role. For example the n-point correlation function and the spacing probabilities have nice representations in terms of this kernel. For the orthogonal and symplectic ensembles...

In this paper, a model is proposed for the kernel in the generalized mixing rule recently formulated by Anderssen and Mead (1998). In order to derive such a model, it is necessary to take account of the rheological significance of the kernel in terms of the relaxation behaviour of the individual polymers involved. This leads naturally to consider a way how additional physical effects, which dep...

Let f(t) be a real continuous function on an interval, and consider the operator function f(X) defined for Hermitian operators X. We will show that if f(X) is increasing w.r.t. the operator order, then for F (t) = ∫ f(t)dt the operator function F (X) is convex. Let h(t) and g(t) be C1 functions defined on an interval I. Suppose h(t) is non-decreasing and g(t) is increasing. Then we will define ...

THIS PAPER DERIVES CONDITIONS for the consistency of kernel estimators of the covariance matrix of a weighted sum of vectors of dependent heterogeneous random variables. This is a problem that has been studied recently by, among others, Newey and West Ž . Ž . Ž . Ž . 1987 , Gallant and White 1988 , Andrews 1991 , Potscher and Prucha 1991b , An̈ Ž . Ž . drews and Monahan 1992 , and Hansen 1992 . ...

Abstract It is well known that the set of isomorphism classes extensions groups with abelian kernel characterized by second cohomology group. In this paper we generalise characterization to a natural class monoids, cosetal extensions. An extension "Equation missing" if for all $$g,g' \in G$$ <mml:mr...

Learning SVM with non positive kernels is is a problem that has been addressed in the last years but it is not really solved : indeed, either the kernel is corrected (as a pre-treatment or via a modified learning scheme), either it is used with some wellchosen parameters that lead to almost positive-definite kernels. In this work, we aim at solving the actual problem induced by non positive ker...

Analyses for test weight, 500-kernel weight, protein content, ash content, and hardness characteristics of fractions ot 13 samples of hard red winter wheat, obtained b>spectrometric separation, revealeci high negatile correlations in most cases between plumpness factors and protein and ash contents, and high positive correlations between plumpness factors and hardness, when the latter is determ...
