In bread wheat (Triticum aestivum L.), crop height is an important determinant of agronomic performance. To map QTLs with additive effects and additive×additive epistatic interactions, 148 recombinant inbred lines and their parents, (‘YecoraRojo’ and Iranian landrace (No. #49)) were evaluated under normal and water deficit conditions. The experiments were carried out on research farms of Mahaba...

The Ostrowski theorem in question is that an additive function bounded (above, say) on a set T of positive measure is continuous. In the converse direction, recall that a topological space T is pseudocompact if every function continuous on T is bounded. Thus theorems of ‘converse Ostrowski’type relate to ‘additive (pseudo)compactness’. We give a di¤erent characterization of such sets, in terms ...

OBJECTIVE The purpose of this study was to compare the effects of a water + electrolyte solution versus plain water on changes in drinking behaviors, hydration status, and body temperatures during wildfire suppression. METHODS Eight participants consumed plain water, and eight participants consumed water plus an electrolyte additive during 15 hours of wildfire suppression. Participants wore a...

Let a, b and n be integers with n > 3. We show that, in the sense of natural density, almost all integers represented by the binary form ax by are thus represented essentially uniquely. By exploiting this conclusion, we derive an asymptotic formula for the total number of integers represented by such a form. These conclusions augment earlier work of Hooley concerning binary cubic and quartic fo...

In various applications the problem of separation of the original signal and the noise arises. For example, in the identification problem for discrete linear and causal systems, the original signal consists of the values of transfer function at some points in the unit disk. In this paper we discuss the problem of choosing the points in the unite disk, for which it is possible to remove the addi...

We study the upper tail behaviors of the local times of the additive stable processes. Let X1(t), · · · , Xp(t) be independent, d-dimensional symmetric stable processes with stable index 0 < α ≤ 2 and consider the additive stable process X(t1, · · · , tp) = X1(t1) + · · · + Xp(tp). Under the condition d < αp, we obtain a precise form of large deviation principle for the local time

We consider problems in modelling job matching in the Czech Republic during the transition to a market economy Special interest is devoted to functional form considerations and the analysis of returns to scale of the matching function This explorative study aims to shed some light into the black box of the matching technology by applying nonparametric esti mation techniques which relax distribu...

When an algebra is graded by a group, any additive character of the group induces a diagonalizable derivation of the ring. This construction is studied in detail for the case of a path algebra modulo relations and its fundamental group. We describe an injection of the character group into the first cohomology group following Assem-de la Peña. Rather general conditions are determined, in this co...

We study three convolutions of polynomials that are inspired by free probability. We define these to be the expected characteristic polynomials of certain random matrices. The symmetric additive and multiplicative convolutions have been studied for a century. The asymmetric additive convolution, and the connection of all of them with random matrices, appears new. We prove that these convolution...
