A formulation of mean-field approximation for layered feedforward stochastic networks is presented. This formulation provides a framework to approximately treat not only averages but also correlations within each layer, so that it can be regarded as an extension to the formulation by Saul and Jordan.

background: anti-microbial agents have been used as a chemotherapeutic agent to improve oral health. this in vitro study was carried out to determine antimicrobial efficacy of different toothpastes and mouthrinses against the oral pathogens.     methods: a total of five toothpastes and five mouthrinses were tested for their antimicrobial activity against three oral pathogens namely, streptococc...

This was a cross-sectional study that investigated pesticide exposure and its risk factors targeting vegetable farmers selected through cluster sampling. The sampling size calculated with P = .05 was 211 vegetable farmers and 37 farms. The mean usage of pesticide was 21.35 liters. Risk factors included damaged backpack sprayer (34.7%), spills on hands (31.8%), and spraying against the wind (58%...

In classical two-stage stochastic programming the expected value of the total costs is minimized. Recently, mean-risk models studied in mathematical finance for several decades have attracted attention in stochastic programming. We consider Conditional Value-at-Risk as risk measure in the framework of two-stage stochastic integer programming. The paper addresses structure, stability, and algori...

linear programming is a helpful and applied method for diet formulation based on minimum cost, but the minimum cost does not always mean maximum profit. this study was carried out to introduce a new diet formulation method based upon maximum profit to be replaced for minimum cost method. a total of 400 one-day-old broiler chicks (ross 308) were employed in the study. all broilers were fed simil...

      In this study, the pharmacokinetic parameters of two marketed tablet formulations of ketoconazole were studied, and the relative bioavailability of the test formulation was compared with a reference formulation. A single dose (12x2) double blind randomized cross-over study of a generic formulation of ketoconazole tablet (2x200 mg), and a commercial brand, Nizoral tablet (2x200 mg, Janssen...

The Vasicek distribution is a two-parameter probability model with bounded support on the open unit interval. This allows for different and flexible shapes plays an important role in many statistical applications, especially modeling default rates field of finance. Although its density function resembles some well-known distributions, such as beta Kumaraswamy models, has not been considered to ...
