Background: Various literature sources have documented a wide spectrum of therapeutic properties of sydnones including anti-inflammatory, anticancer, antimicrobial activities. Phenyl styryl ketones and their derivatives as members of the chalcone family have also been reported as significant bioactive molecules. The current study was initiated to e

In the present paper we introduce a notion of G-decompositions of matrices. Main result of the paper is that a symmetric matrix Am has a G-decomposition in the class of stochastic (resp. substochastic) matrices if and only if Am belongs to the set Um (resp. Um). To prove the main result, we study extremal points and geometrical structures of the se

Purpose: Biodegradable microparticles and nanoparticles are receiving increased attention for their ability to serve as a vi- able carrier for site-specific delivery of genes, drugs and other biomolecules. Electrospraying represents a challenging tech- nology which allows for the preparation of biodegradable particles with high bioavailability, goo

We study the phase diagrams for the Potts model with restricted competing nearest-neighbor interactions J 1 and ternary interactions J pt on a Cayley tree of arbitrary order k. At vanishing temperature, the phase diagram is fully determined for all values and signs of J pt /J 1 and T/J 1. The phase diagrams are obtained from stability conditions, a

High processing time is required to classify genomic sequences and to identify protein coding of a DNA sequence. While computer performance has been driven largely by decreasing the size of chips while increasing the number of transistors they contain, the current computing trend is multicore system in which two or more independent cores are integr

In this paper, we shall give a general program of proving non-ergodicity of Volterra QSO (quadratic stochastic operator). This program already mentioned in the first author's doctor of science thesis. However, there is another program to do so [1]. Here, we are going to provide some examples to support our program. It is worth pointing out that

Human auditory system has been successfully employed in speech compression to reduce bit rate requirement. Previous researches on speech compression stated that the use of simultaneous masking and/or temporal masking reduced the bit rate requirement while maintained perceptual quality. However, the benefit of using auditory masking in speech coding

We study the phase of diagrams for the Potts model on a Cayley tree-like lattice, called Quadrangle Chandelier, with competing nearest-neighbour interactions J1,prolonged next nearest-neighbour interactions Jp and one-level quadrangle nearest-neighbour interactions Jo. The phase diagram is studied for several ranges of the competing parameters and

Judging things is a part of their perception, and we cannot imagine a curriculum without precisely defining its concept. The concept of curriculum in the field of teaching Arabic to non-native speakers has specific characteristics that distinguish it from other curricula of other languages for non-native speakers. These characteristics are mainly t

Introduction: Historically, animal models for osteoarthritis have been established to facilitate the study of the pathogenesis of osteoarthritis and the potential medical treatment. The anterior cruciate ligament transection (ACTL) and partial meniscal resection model in rabbits have been widely used. The aim of the study was to establish a more ef
