background : determining the validity of current median sensory nerve conduction techniques for diagnosis of carpal tunnel syndrome (cts). methods: eighty five patients with clinical diagnosis of cts were compared with the same number of healthy people. the validity of electrodiagnostic tests were compared in a case-control manner. these electrodiagnostictechniques included long-segment, short-...

Mortgagors face a trade off between paying more points and a lower interest rate. The theoretical prediction is that borrowers with a higher probability of prepayment would opt for a loan with fewer points and higher interest rate. Another theoretical prediction is that once incurred, points become sunk costs, hence should not affect borrowers’ refinancing decisions in the future. Utilizing ind...

In this paper, a self starting two step continuous block hybrid formulae (CBHF) with four Off-step points is developed using collocation and interpolation procedures. The CBHF is then used to produce multiple numerical integrators which are of uniform order and are assembled into a single block matrix equation. These equations are simultaneously applied to provide the approximate solution for t...

normal 0 false false false en-us x-none ar-sa background: obesity or being overweight is a major health problem in iran. only few studies are available that compare the obesity prevalence by four different available criteria. the aim of this study was to determine the prevalence of overweight and obesity among isfahani adolescents based on four different definitions. materials and methods: this...

We introduce a new type of Steiner points, called off-centers, as an alternative to circumcenters, to improve the quality of Delaunay triangulations. We propose a new Delaunay refinement algorithm based on iterative insertion of off-centers. We show that this new algorithm has the same quality and size optimality guarantees of the best known refinement algorithms. In practice, however, the new ...

the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...

INTRODUCTION Country-specific cut-off points for defining central obesity in black Africans are long overdue. METHODS Anthropometric data from 215 (51.4%) male and 203 (48.6%) female patients seen in Gaborone between 2005 and 2015 were analysed to establish appropriate cut-off points for waist circumference (WC) corresponding to a body mass index (BMI) of 30 kg/m2. Relative risks for cardiome...

Trade-off (aka Pareto) curves are typically used to represent the trade-off among different objectives in multiobjective optimization problems. Although trade-off curves are exponentially large for typical combinatorial optimization problems (and infinite for continuous problems), it was observed in [PY1] that there exist polynomial size approximations for any > 0, and that under certain genera...

OBJECTIVE To review the spot protein:creatinine ratio and albumin:creatinine ratio as diagnostic tests for significant proteinuria in hypertensive pregnant women. DESIGN Systematic review. DATA SOURCES Medline and Embase, the Cochrane Library, reference lists, and experts. Review methods Literature search (1980-2007) for articles of the spot protein:creatinine ratio or albumin:creatinine ra...
