PURPOSE To determine whether Heidelberg Retina Tomograph (HRT; Heidelberg Engineering, Dossenheim, Germany) classification techniques and investigational support vector machine (SVM) analyses can detect optic disc abnormalities in glaucoma-suspect eyes before the development of visual field abnormalities. METHODS Glaucoma-suspect eyes (n = 226) were classified as converts or nonconverts based...

OBJECTIVES This study sought to 1) test the hypothesis that in the setting of bradycardia and drug-induced action potential prolongation, multiple foci of early afterdepolarizations (EADs) result in beat to beat changes in the origin and direction of the excitation wave front and are responsible for polymorphic arrhythmias; and 2) determine whether EADs may initiate nonstationary reentry, givin...

This study empirically compared two methods for reengineering a procedural system to an object-oriented system. Our hypothesis was that it is possible to support this process with a repeatable method. The first method was manual and was used as a baseline for evaluating the second method, which was repeatable and based on analysis of procedure coupling. The repeatable method was found to be eff...
