Since the turn of the century there have been several notions of convergence for subsets of metric spaces appear in the literature. Appearing in as a subset of these notions is the concepts of epi-convergence. In this paper we peresent definitions of epi-Cesaro convergence for sequences of lower semicontinuous functions from $X$ to $[-infty,infty]$ and Kuratowski Cesaro convergence of sequence...

Catheter tip dislocation is the main complication of permanent pacemaker implantation using the subclavian vein. In this study of 50 patients we compared the incidence of complications using two endocardial electrodes specially designed to prevent tip dislocation. One catheter had a helical endocardial electrode and the other had retractable nylon barbs. The helical electrode was superior in ev...

This paper details the development and application of the RDS-SUMO-CEASIOM-EDGE rapid-CFD tool. It uses the RDS CAD model as geometry for automated meshing and CFD analysis to produce an aero-data base for control and stability analysis. It is applied to two non-conventional design proposals, an asymmetric twin-prop aircraft and an airliner with rear Open Rotor propulsion, retractable canard, a...

BACKGROUND Reduced estimated glomerular filtration rate (eGFR) using the cystatin-C derived equations might be a better predictor of cardiovascular disease (CVD) mortality compared with the creatinine-derived equations, but this association remains unclear in elderly individuals. AIM The aims of this study were to compare the predictive values of the Chronic Kidney Disease Epidemiology Collab...

This study examines the value of spin-echo-based fMRI for cognitive studies at the main magnetic field strength of 3 T using a spin-echo EPI (SE-EPI) sequence and a Stroop color-word matching task. SE-EPI has the potential advantage over conventional gradient-echo EPI (GE-EPI) that signal losses caused by dephasing through the slice are not present, and hence although image distortion will be t...

BACKGROUND Patients with nonischemic left ventricular cardiomyopathy (LVCM) and ventricular tachycardia (Vt) have complex 3-dimensional substrate with variable involvement of the endocardium (ENDO) and epicardium (EPI). The purpose of this study was to determine whether ENDO unipolar (UNI) mapping with a larger electric field of view could identify EPI low bipolar (BIP) voltage regions in patie...

Objetivo: Evaluar los cambios refractivos y topográficos producidos por crosslinking EPI-ON (CXL EPI-ON) vs EPI-OFF EPI-OFF) en pacientes con queratocono. Introducción: Queratocono es una enfermedad bilateral progresiva, que puede causar discapacidad visual. La progresión de la tratada CXL, procedimiento fortalece córnea. Material métodos: Se revisaron retrospectivamente datos fueron tratados C...

BACKGROUND AND PURPOSE RS-EPI has been suggested as an alternative approach to EPI for high-resolution DWI with reduced distortions. To determine whether RS-EPI is a useful approach for routine clinical use, we implemented GRAPPA-accelerated RS-EPI DWI at our pediatric hospital and graded the images alongside standard accelerated (ASSET) EPI DWI used routinely for clinical studies.
