BACKGROUND Objective biomarkers of product use and protocol compliance are urgently needed. We compared the sensitivity and specificity of DNA and protein-based biomarkers, obtained from used vaginal gel applicators, to visual inspection of those applicators under ambient light (visual inspection of returned applicator [VIRA]) and ultraviolet light (UVL). METHODS Forty women inserted hydroxye...

This paper is on production planning and inventory control in systems where manufacturing and remanufacturing operations occur simultaneously. Typical for these hybrid systems is, that both the output of the manufacturing process and the output of the remanufacturing process can be used to fulfil customer demands. Here, we consider a relatively simple hybrid system, related to a single componen...

This paper deals with the coordination of manufacturing, remanufacturing and returns acceptance control in a hybrid production-inventory system. We use a queuing control framework, where manufacturing and remanufacturing are modelled by single servers with exponentially distributed processing times. Customer demand and returned products arrive in the system according to independent Poisson proc...

BACKGROUND The platelet products thromboxane A2 and serotonin have been shown to cause constriction of well-developed coronary collateral vessels. This study was performed to determine whether intravascular platelet activation produced with platelet activating factor (PAF) can cause a decrease in coronary collateral blood flow. METHODS AND RESULTS Collateral vessel growth was induced by embol...

May-Happen-in-Parallel (MHP) is a fundamental analysis to reason about concurrent programs. It infers the pairs of program points that may execute in parallel, or interleave their execution. This information is essential to prove, among other things, absence of data races, deadlock freeness, termination, and resource usage. This paper presents an MHP analysis for asynchronous programs that use ...

The main contribution of this paper is to present an extension to AspectJ compiler ajc-1.5.0 for security hardening. The extension consists of two pointcuts that can capture the returned computable values of methods in both the execution scope or following a method invocation. The returned values in programs are the results of operations done in the execution scope of methods. They are signific...

Abstract Nowadays, companies need to take responsibility for addressing growing markets and the expectations of their customers survive in a highly competitive context that is progressing on daily basis. Rapid economic changes increasing pressure global have led pay special attention supply chains. As result, this research, mathematical model proposed minimize closed loop chain costs taking int...

These days, most organisations use celebrity endorsement as a communication technique for inducing consumers' perception and attitude towards buying their products. This paper aims to examine celebrities' credibility on Globacom telecommunication products in Ilorin Metropolis. A total of 273 usable copies the questionnaire administered target respondents were returned. multi-stage sampling meth...
