Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

We study $B\ensuremath{\rightarrow}\ensuremath{\pi}\ensuremath{\pi}$ decay with a modified perturbative QCD approach. The branching ratios and $CP$ violation are calculated the transverse momenta of partons considered. Sudakov factor associated each meson is included to suppress soft contribution in QCD. With wave function $B$ obtained QCD-inspired relativistic potential model being used, suppr...

Stromal acidification has been reported to mediate reduced osmotic potential (psi(pi)) effects on photosynthesis in the isolated spinach chloroplast (Berkowitz, Gibbs 1983 Plant Physiol 72: 1100-1109). To determine if stromal acidification mediates osmotic dehydration inhibition of photosynthesis in vivo, the effects of a weak base (NH(4)Cl), which raises stromal pH, on CO(2) fixation of vacuum...

The second moment of the isospin–2 structure function of the pion, F π+ 2 +F π− 2 −2F π 0 2 , is determined by the pion matrix element of a four–quark operator of twist 4. This isospin–2 operator cannot mix with lower–dimensional operators, and thus provides a clean probe of the quark–quark correlations in the pion. We calculate the matrix element in the effective chiral theory based on the ins...

In previous works we have shown that certain pi-conjugated organic molecules possess nontotally symmetric vibrations that break the maximum hardness (MHP) and minimum polarizability principles (MPP). We have also derived a set of simple rules to determine a priori without calculations whether a particular pi-conjugated organic molecule violates these two principles. In the present work, we gene...

This paper put forward a new method of co-occurrence matrix to describe image features. In this paper putting a new implemented work which is comparison with texton co-occurrence matrix to describe image features. Maximum work done successfully using texton co-occurrence matrix. A new class of texture features based on the co-occurrence of gray levels at points. These features are compared with...

Résumé : La résolution de problèmes à états et actions continus par l’optimisation de politiques paramétriques est un sujet d’intérêt récent en apprentissage par renforcement. L’algorithme PI est un exemple de cette approche, qui bénéficie de fondements mathématiques solides tirés de la commande stochastique optimale et des outils de la théorie de l’estimation statistique. Dans cet article, nou...

Efficient utilization of available resources is a key concept in embedded systems. This paper is focused on providing the support for managing dynamic reconfiguration of computing resources in the programming model. We present an approach to map occam-pi programs to a manycore architecture, Platform 2012 (P2012). We describe the techniques used to translate the salient features of the occam-pi ...
