| In this paper, we present a design method for AND-OR-EXOR three-level networks, where a single two-input EXOR gate is used. The network realizes an exclusive-OR of two sum-of-products expressions (EX-SOP), where the two sum-of-products expressions (SOP) cannot share products. The problem is to minimize the total number of product in the two SOPs. We introduced the -equivalence of logic functi...

Based on the 19 selected representative chemical enterprises in jiangsu province, we investigate safety risk situation of from aspects personnel technical level, equipment failure, major hazard sources, production process, environment, accident, certification, assessment and emergency response capacity. We found following problems: most part staffs education is below undergraduate course; have ...

For site-specific soil ecological risk assessments (SERAs), an integrated chemical, ecotoxicological, and analysis needs to be performed. The SERA guidelines of international institutions countries recommend that a initiated at the screening level save time social economic cost; however, they provide no unified test species for this level. This study performed SERAs field soils confirmed import...

We use the method of deficit accumulation to describe prevalent and incident levels of frailty in community-dwelling older persons and compare prevalence rates in higher income countries in Europe, to prevalence rates in six lower income countries. Two multi-country data collection efforts, SHARE and SAGE, provide nationally representative samples of adults aged 50 years and older. Forty items ...

The formulation of steady-state initialization problems for fluid systems is a non-trivial task. If steady-state equations are specified at the component level, the corresponding system of initial equations at the system level might be overdetermined, if index reduction eliminates some states. On the other hand, steady-state equations are not sufficient to uniquely identify one equilibrium stat...

PURPOSE Childhood obesity rates are increasing globally. Physical activity is one behavioral variable that influences weight status. Participation in physical activity requires basic gross motor proficiency in early childhood. The purpose of this study was to examine the relationship between gross motor skill level and weight status in a large national representative sample of kindergarten-aged...

In this paper a set of de nitions describing general real number representation sys tems is presented Our purpose is to nd a su ciently wide model de nition including classical systems signed digit notation linear numeration systems p adic numbers symmetric level index arithmetic but speci c enough to make it possible to build some practical results We focuse on the redundancy property and the ...

INTRODUCTION Chronic diseases have emerged as a major health threat to the world's population, particularly in developing countries. We examined the prevalence of selected risk factors for chronic disease and the association of these risk factors with sociodemographic variables in a representative sample of adults in rural Vietnam. METHODS In 2005, we selected a representative sample of 2000 ...

The aim of this paper is to analyze the long-term and short-term risk components in Chinese financial market and to compare them with those in mature financial markets. For this purpose a most recently proposed Semi-APARCH is applied to the Shanghai Index and the Shenzhen Index, and four financial indexes in mature markets. A few important empirical findings are achieved. Firstly, the current l...
