BACKGROUND Data from BreastScreen Australia Screening and Assessment Services (SAS) for 2002-2010 were analysed to determine whether some SAS characteristics were more conducive that others to high screening performance, as indicated by high priority performance indicators and standards. MATERIALS AND METHODS Indicators investigated related to: numbers of benign open biopsies, screen-detected...

PURPOSE To examine the subarachnoid space (SAS) of eyes with pathologic myopia and analyze the characteristics of the SAS and the surrounding tissues by swept-source optical coherence tomography (OCT). METHODS One hundred thirty-three eyes of 76 patients with pathologic myopia (spherical equivalent refractive error of >-8.00 diopters (D) or an axial length >26.5 mm) and 32 eyes of 32 subjects...

BACKGROUND Cardiovascular diseases leading to pacemaker implantations are suspected of being associated with a high rate of undiagnosed sleep apnea syndrome (SAS). We sought to determine the prevalence and consequences of SAS in pacemaker patients according to pacing indications: heart failure, symptomatic diurnal bradycardia, and atrioventricular block. METHODS AND RESULTS Ninety-eight conse...

Randomization as a method of experimental control has been extensively used in clinical trials. Generating the randomization schedule has been an essential part of some trials. We discuss how to use SAS programming and SAS PROC PLAN to generate the randomization schedule. The issues related to randomization are also discussed. Case studies are used to illustrate the use of SAS programming and S...

Kent and O'Quigley (1988) apply the concept of information gain to define a measure of dependence (R-squared measure) between explanatory variables and a censored response variable within the framework of the Cox model. Two SAS macros to calculate this measure are presented. The first one is based on a Newton-Raphson search and makes use of the SAS IML procedure. The second one is a simple grid...

 Abstract— This paper studies the semi-analytic solution (SAS) of a power system’s differential-algebraic equation. A SAS is a closed-form function of symbolic variables including time, the initial state and the parameters on system operating conditions, and hence able to directly give trajectories on system state variables, which are accurate for at least a certain time window. A two-stage SA...
