In a categorification of tensor products of fundamental representations of quantum sl(k) via highest weight categories, the indecomposable tilting modules descend to the canonical basis. Projective functors map tilting modules to tilting modules implying the coefficients of the canonical basis of tensor products of finite dimensional, irreducible representations under the action of the Chevalle...

Pseudoepitheliomatous hyperplasia is a benign reactivated epithelial lesion secondary to another pathology, whose incidence is difficult to establish. There still exist controversies regarding the origin and pathogenesis of these lesions. For this purpose, we performed an immuno-histochemical study upon 20 cases of oral pseudoepitheliomatous hyperplasia associated with inflammatory and neoplast...

in recent decades the expansion of building infractions in many cities of developing countries, regarding one of the most important issues for denizens and urban managers. in most cases, this inordinate development will be challengeable because of cursory control and improprieties management. this study aimed at investigation and evaluation the building infractions, sort of infractions and a co...

The conditions under which matrix orientifolding and supersymmetry transformations commute are known to be stringent. Here we present the cases possessing four or eight supercharges upon Z3 orbifolding followed by matrix orientifolding. These cases descend from the matrix models with eight plus eight supercharges. There are fifty in total, which we enumerate. e-mail: [email protected] ...

The air-filled tracheal respiratory system of insects prevents them from diving deeply in water. It is argued that this is the major factor in preventing insects from colonizing the open sea: they cannot descend sufficiently deeply in the daytime to escape being eaten by fish.

Two nonlinear conjugate gradient-type methods for solving unconstrained optimization problems are proposed. An attractive property of the methods, is that, without any line search, the generated directions always descend. Under some mild conditions, global convergence results for both methods are established. Preliminary numerical results show that these proposed methods are promising, and comp...

AIM Developing a method of maximizing maternal expulsive effort should be of great value in reducing the number of cesarean sections or instrumental deliveries. Various investigations have shown that use of a dental support device (DSD) increases the isometric strength of different muscle groups. The aim of our study was to investigate the role of a DSD in second stage of pushing. METHODS Nul...

In this study, a fuzzy rule-based optimal controller is designed for nonlinear dynamical systems. The direct second order method (or directdescend-curvature algorithm) with a modification called “modified descend controller (MDC)” is used for calculating the parameters of the fuzzy feedback controller. The optimal control problem defined here has dynamic constraints of nonlinear system states a...
