A numerical investigation has been performed to study the effect of eccentricity on unsteady state, laminar aiding mixed convection in a horizontal concentric and eccentric cylindrical annulus. The outer cylinder was kept at constant temperaturewhile inner heated with heat flux. involved solution transient momentum (Navier-Stokes) energy equation using finite difference method (FDM), where body...

Arias et al in the article 'A Narrow QRS Complex Tachycardia with an Apparently Concentric Retrograde Atrial Activation Sequence' describe a case with spontaneous intra atrial block along the mitral isthmus to explain the change in atrial activation [1]. This phenomenon has been described during radiofrequency ablation while ablating along the lateral mitral annulus for a left free wall pathway...

Recently, the image of a Schwarzschild black hole with an accretion disk has been revisited, and it showed that ``photon ring,'' defined as highly bent light rays intersect plane more than twice, is extremely narrow makes negligible contribution to total brightness. In this paper, we investigate observational appearance optically geometrically thin around hairy in Einstein-Maxwell-scalar model....

We propose a method that computes a conformal mapping from a multiply connected mesh to the so-called slit domain, which consists of a canonical rectangle or disk in which 3D curved landmarks on the original surfaces are mapped to concentric or parallel lines in the slit domain. In this paper, we studied its application to brain surface parameterization. After cutting along some landmark curve ...
