BACKGROUND Quality control (QC) and evaluation of HIV rapid test procedures are an important aspect of HIV prevention trials. We describe QC and performance of two rapid tests, Determine™ and Uni-Gold™ used in a microbicide clinical trial in rural KwaZulu-Natal, South Africa. METHODS/RESULTS Internal QC of both HIV rapid tests was conducted at the trial site using a Uni-Gold control kit (Uni-...

in this paper we review some recent ideas of synchronization theory. we apply this theory to study the different synchronization aspects of uni-directionally coupled pair of chaotic one-dimensional gaussian maps.

We present a new class of second-order uniication problems, which we have called linear. We deal with completely general second-order typed uniication problems, but we restrict the set of uniiers under consideration: they instantiate free variables by linear terms, i.e. terms where any-abstractions bind one and only one occurrence of a bound variable. Linear second-order uniication properly ext...

The aim of this study was to evaluate the flexural strength of acrylic resin bars by varying the types of resin polymerization and reinforcement methods. Fourteen groups (N=10) were created by the interaction of factors in study: type of resin (self-cured (SC) or heat-cured (HC)) and reinforcement method (industrialized glass fiber (Ind), unidirectional glass fiber (Uni), short glass fiber (Sho...

sin staff as an assistant professor of psychology in 1930, after receiving his Ph.D. at Stanford Uni versity. Almost immediately Dr. Harlow set out to create a primate research facility at Wisconsin, which has evolved into one of the most eminent facilities of its kind in the world. His primary re search interests have focused on learning abilities of rhesus monkeys, effects of brain lesions on...

Most modern classical processors support so-called von Neumann architecture with program and data registers. In present work is revisited similar approach to models of quantum processors. Deterministic pro-grammable quantum gate arrays are considered as an example. They are also called von Neumann quantum processors here and use conditional quantum dynamics. Such devices have some problems with...

First published September 14, 2011; doi:10.1152/ajprenal.00463.2011.— Fetal uninephrectomy (uni-x) in male sheep at 100 days of gestation (term 150 days) reduces overall nephron endowment without a...

The health problems caused by the frequent relapse of papillary thyroid carcinoma (PTC) remain a worldwide concern since morbidity rate PTC ranks highest among cancers. Residues from contralateral central lymph node metastases (con-CLNM) are key reason for persistence or recurrence unilateral (uni-PTC); however, ability to assess status con-CLNM in uni-PTC patients is limited. To clarify risk f...
