Most of the calcium in the body is stored in bone. The rest is stored elsewhere, and calcium signalling is one of the most important mechanisms of information propagation in the body. Yet, many questions remain open. In this work, we initially consider the mathematical model proposed in Atri et al. [1]. Omitting diffusion, the model is a system of two nonlinear ordinary differential equations (...

BACKGROUND The current study aims to identify predictors of pathological gambling (PG) severity, taking gender differences into account, in an outpatient sample of pathological gamblers seeking treatment. METHODS The sample for this study consisted of 103 subjects (51 women and 52 men) meeting current DSM-IV-TR criteria for PG. Linear and logistic regression analyses were used to examine diff...

Designing the physical distribution network in a supply chain is an important strategic planning problem with undeniable implications towards tactical and operational planning success. In this paper we consider a distribution network made up of four tiers, involving factories, central warehouses, regional warehouses as well as customer zones. The objective is to select the optimal numbers and l...

Simulation of weather scenery in computer graphics (CG) is an important issue that has a wide range of applications related to image content, such as in movies and in various landscape simulations. In general, research to date into CG lightning has focused on generating a lightning pattern by applying probability and statistics techniques, which do not consider the generating mechanism of light...

Recently, displaying natural phenomena such as smoke has become a topic of interest in computer graphics. The ability to simulate the complex shapes and motion of the smoke particles is not only important but is also a difficult problem to solve. In this paper, we propose a method of displaying swirling smoke, including the consideration of its passage round obstacles. By using the idea of meta...

BEA study uses novel data to explore export methods Over the past decade, interest in the industrial organization of international trade has exploded, as new microdata sets have led to the development of heterogeneous firm trade models that link firm characteristics and export participation. economist at the Bureau of Economic Analysis (BEA), has added to the literature with a recent paper that...
