development of new cultivars with high grain yield (gy) stability and good adaptability under both terminal drought stress (tds) and normal irrigation conditions, which plays important role in production of wheat, is one of the major goals of wheat breeding program for cold dry areas of iran. the objective of this investigation was to study the stability and adaptability of gy and genotype × lo...

background motor intervention plays an important role in reducing the disabilities of down syndrome (ds). a lack of balance and postural control has created motor problems in ds patients. therefore, the aim of this study was to examine the effect of backward walking on postural stability of ds patients. materials and methods sixteen ds children with 8-10 age range were selected by convenience s...

the objective of this research was to study genotype×environment interaction and to evaluate stability analysis of grain yield in chickpea genotypes under rainfed condition. experimental material was comprised of 17 genotypes with the experiments carried out in rcbd of four replications at kermanshah, lorestan, ilam, gachsaran and gorgan research stations during the two years of 2003-2004. the ...

M often employ market response models as decision aids and historical information of competitors’ market outcomes to aid their competitive decisions in oligopolistic settings. However, little is known about how access to a decision aid or the availability of competitors’ market outcomes impact a firm’s competitive decisions (e.g., prices) or market outcomes resulting from those decisions (e.g.,...

In this paper we introduce a stability radius for a wide class of linear innnite-dimensional time-varying systems under structured time{varying perturbations. A framework is presented which allows the same degree of unboundedness in the perturbations as in the generator of the nominal model.

We clarify the explici structure of the Hurwitz quaternion order, which is of fundamental importance in Riemann surface theory.

The paper is an attempt to generalize a methodology [1; 93] and [2, 3; 95], which is similar to the bounded-input bounded-output (BIBO) method currently widely used [4-9] for the system stability studies. The presented in [1, 2] methodology allows decomposition of input space into bounded subspaces and defining for each subspace its bounding surface. It also defines a corresponding predefined c...

This note introduces a stability radius for discrete time linear time-varying systems on Banach spaces under structured time-varying perturbations of multi{output feedback type. We derive counterparts to some results established for time-varying and/or innnite dimensional diierentiable systems in 3], 6].

We describe the synthesis of an abasic RNA phosphoramidite carrying a photocleavable 1-(2-nitrophenyl)ethyl (NPE) group at the anomeric center and a triisopropylsilyloxymethyl (TOM) group as 2'-O-protecting group together with the analogous DNA and the 2'-OMe RNA abasic building blocks. These units were incorporated into RNA-, 2'-OMe-RNA- and DNA for the purpose of studying their chemical stabi...
