This paper proposes a new mathematical and computational tool for inferring the geometry of shapes known only through approximations such as triangulated or digital surfaces. The main idea is to decouple position shape boundary from its normal vector field. To do so, we extend classical geometric measure theory, cycle, so that it takes input not surface but also We formalize current in oriented...

mitral valve prolapse (mvp) is a relatively frequent valvular abnormality. in both children and adults with mvp, an increased incidence of ventricular arrhythmias has been reported. qt dispersion, defined as the difference in duration between the longest qt interval and the shortest one, for a given set of electrocardiographic leads has been proposed as a sign of regional difference in cardiac ...
