Refining the Eikonal Model to Reproduce the Influence of Atrial Tissue Geometry on Conduction Velocity

open access: yesCurrent Directions in Biomedical Engineering, 2022
Atrial fibrillation is responsible for a significant and steadily rising burden. Simultaneously, the treatment options for atrial fibrillation are far from optimal. Personalized simulations of cardiac electrophysiology could assist clinicians in the risk

Thick Walls, Thin Data [PDF]

open access: yesCirculation: Cardiovascular Imaging, 2017
> “Baseball is a game of inches.” > > ―Branch Rickey If baseball is a game of inches, then modern cardiology is a discipline of millimeters. Just over 3 millimeters separates abnormal from normal myocardial thickness in any of the myocardial segments.

A Study of Quantifying Thickness of Ferromagnetic Pipes Based on Remote Field Eddy Current Testing

open access: yesSensors, 2018
Remote Field Eddy Current Testing (RFECT) has broad applications in ferromagnetic pipe testing due to the same testing sensitivity to inner and outer wall defects.

Gallbladder wall thickness distortion by ascites [PDF]

open access: yesAmerican Journal of Roentgenology, 1981
Eight patients with sonographically demonstrated ascites adjacent to or surrounding a gallbladder wall of normal thickness are described. In two patients, improper transducer placement or angulation caused apparent gallbladder wall thickening. Two in vitro experiments, one with a balloon phantom and the other with a resected gallbladder, confirmed that

Improving the wall thinning of the transition shoulder with anti-wedge upset rolling in cross wedge rolling hollow parts

open access: yes工程科学学报, 2016
Wall thinning occurs at transition shoulders in cross wedge rolling (CWR) hollow parts without a mandrel, which will reduce the mechanical strength of the parts, so improving the wall thickness of the shoulder must be resolved.

Effect of Anodization Parameters on the Surface Morphology and Photoelectrochemical Properties of TiO2 Nanotubes

open access: yesInternational Journal of Electrochemical Science, 2017
Titanium sheets are anodized to prepare titanium dioxide nanotubes (TiO2 NTs) with varying chemical polishing times, anodizing voltages, anodizing times and NH4F electrolyte concentrations. The surface morphology of the TiO2 NTs is observed by a Scanning

Does bladder wall thickness decrease when obstruction is resolved? [PDF]

open access: yes, 2012
The aim of the current study was to determine if sonographic bladder wall thickness diminishes after symptomatic obstruction is resolved in female patients after stress incontinence ...

Can HRCT be used as a marker of airway remodelling in children with difficult asthma? [PDF]

open access: yes, 2006
BACKGROUND: Whole airway wall thickening on high resolution computed tomography (HRCT) is reported to parallel thickening of the bronchial epithelial reticular basement membrane (RBM) in adult asthmatics. A similar relationship in children with difficult

Associations between blood glucose and carotid intima-media thickness disappear after adjustment for shared risk factors: the KORA F4 study. [PDF]

open access: yes, 2012
The association between blood glucose and carotid intima-media thickness (CIMT) is considered to be established knowledge. We aimed to assess whether associations between different measures of glycaemia and CIMT are actually independent of anthropometric

Optimal Force–Time Integral for Pulmonary Vein Isolation According to Anatomical Wall Thickness Under the Ablation Line

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundLow contact force and force–time integral (FTI) during catheter ablation are associated with ineffective lesion formation, whereas excessively high contact force and FTI may increase the risk of complications.
