PURPOSE To investigate whether lamina cribrosa (LC) defects are associated with optic disc morphology in primary open angle glaucoma (POAG) eyes with high myopia. METHODS A total of 129 POAG patients and 55 age-matched control subjects with high myopia were evaluated. Three-dimensional scan images obtained by swept source optical coherence tomography were used to detect LC defects. Radial B-s...

A common objective in the web transport industry is to increase the velocity as much as possible. Some disturbances drastically limit this velocity. Time-varying eccentricity of the rolling winder is one of the major disturbances which affect the quality of the rolling winder. This unsuitable factor can lead to a web break for a high-speed winding process. The main contribution of this work is ...

optical, fiber optics, photonic subsystems, photonics, lightwave components A new technique is presented for measurement of the differential group delay (DGD) between principal states of polarization of an optical device, with a demonstrated accuracy and resolution of roughly 50 attoseconds (50 x 10.18 s). Accuracy was directly assessed by measurement of a crystal quartz DGD standard. For the f...

Abstract Atrial fibrillation (AF) is the most common supraventricular arrhythmia. Despite significant advances in its treatment, it still remains one of leading causes cardiovascular morbidity and mortality. In last two decades, pulmonary vein isolation (PVI) was developed as effective treatment option. The reported effectiveness a single ablation procedure ranges from 40% to 69% with single, u...

The usefulness of a virtual character depends on its ability to fulfill the user’s expectations: among other aspects, the character’s appearance should match her/his personality as well as her/his behavior [11]. It has indeed been shown that the better a character looks the part, the more believable and effective she/he will be in the narrative [13, 8]. This paper presents a system which genera...

We present a noncircularity measure for 2D (two-dimensional) shapes and an approach to the computation of the Euler number based on the Slope Chain Code (SCC). The SCC was developed for representing and analyzing open and closed curves in the 2D domain. Now, in this paper we describe more properties of the SCC, such as: the independence of scaling and starting point for simple closed curves, ar...

This paper focuses on the buckle propagation pressure of a pipe-in-pipe system under uniform external pressure. After validation finite element model used in this research, several effects were studied. At first, initial imperfection inner pipe, including ovality and eccentricity, checked out. Second, influence scantling outer pipes was tested. It found that dominant factor which affects mode i...

In analogy to the Eisenfeld-Lakshmikanthammeasure of nonconvexity and theHausdorffmeasure of noncompactness, we introduce two mutually equivalent measures of noncircularity for Banach spaces satisfying a Cantor type property, and apply them to establish a fixed point theorem of Darbo type for multifunctions. Namely, we prove that every multifunction with closed values, defined on a closed set a...
