We carry out a detailed analysis of the light Higgs bosons in supersymmetric leftright models (SLRM). This includes models with minimal particle content and those with additional Higgs superfields. We also consider models with non-renormalizable higher-dimensional terms. We obtain an upper bound on the mass of the lightest CP -even neutral Higgs boson in these models. The upper bound depends on...

The large number of municipal solid waste (MSW) landfills and the many hazardous materials which they contain pose a serious threat to both surrounding environment and human populations. Once waste is deposited at the landfill, pollution can arise from the percolation of leachate to the porous ground surface. Contamination of groundwater by such leachate renders it and the associated aquifer un...

Using the matrix factorization technique in machine learning is very common mainly in areas like recommender systems. Despite its high prediction accuracy and its ability to avoid over-fitting of the data, the Bayesian Probabilistic Matrix Factorization algorithm (BPMF) has not been widely used on large scale data because of the prohibitive cost. In this paper, we propose a distributed high-per...

Background Understanding the level of public satisfaction with a family physician plan as well as the relevant factors in this respect, can be employed as valuable tools in identifying quality of services. Objective To determine the factors affecting public dissatisfaction with an urban family physician plan in Iran. Methods This cross-sectional study was conducted from January 2014 through...

Wet meadows are one of the most important ecological components in floodplain, and are among the most dynamic ecosystems. Understanding the development of wet meadows and contributing environmental factors can provide better support for wetland management. Carex meadows in East Dongting Lake National Nature Reserve (EDLNNR) provide vital wintering ground for thousands of migratory waterbirds, a...

The present study examined the relationship between workload and work satisfaction of personnel working in accommodation and nutrition establishments. The study used a cluster sampling method. Ten accommodation and nutrition establishments were included as a cluster, and the sample group consisted of 340 personnel working at these establishments. “Work satisfaction” and “workload” scales were u...

OBJECTIVE To determine the relationship between hospital length of stay (LOS) and quality of care in patients admitted for congestive heart failure (CHF). METHODS This observational study was conducted in the medical wards of the Geneva University Hospitals, Geneva, Switzerland. A random sample of 371 patients was drawn from the 1084 patients discharged alive with a principal diagnosis of CHF...

PURPOSE The purpose of this study was to investigate the contribution of actual cardiovascular disease (CVD) risk, as well as, individual, psychosocial, and work-related factors as predictors of CVD risk perception among Korean blue-collar workers.

OBJECTIVE This study examined access to mental health providers in health maintenance organization (HMO) networks. METHODS A telephone survey was conducted with a stratified random sample of mental health providers listed as being in a network for at lease one of six HMOs operating in Connecticut (response rate=72%; N=366). Data were collected between December 2006 and March 2007. Measures in...
