In this paper, stress and strain equations are developed for the left ventricle mainly to nd the innuence of the ventricle's shape on wall stresses. Here, the ventricle is assumed to be a thick-walled truncated conical shell and large elastic deformation theory is applied. Our model is compared to corresponding results approximating the left ventricle as a spherical shell. Clinically relevant p...

We consider a spherical thick 3-brane immersed in a five-dimensional bulk spacetime. We demonstrate how the thick brane equation of motion expanded in powers of the thickness of the brane can be obtained from the expected junction conditions on the boundaries of thick brane with the two embedding spacetimes. It is shown that the finite thickness leads to a faster collapse of the spherical shell...

We study the semiclassical evolution of a self-gravitating thick shell in Anti-de Sitter space-time. We treat the matter on the shell as made of quantized bosons and evaluate the back-reaction of the loss of gravitational energy which is radiated away as a non-adiabatic effect. A peculiar feature of anti-de Sitter is that such an emission also occurs for large shell radius, contrary to the asym...

This paper presents a new method for creating a thick shell tetrahedral mesh from a triangular surface mesh. Our main goal is to create the thickest possible shell mesh with the lowest possible number of tetrahedrons. Low count tetrahedral meshes is desirable for animating deformable objects where accuracy is less important and to produce shell maps and signed distance fields. In this work we p...

The optical flash accompanying GRB 990123 is believed to be powered by the reverse shock of a thin shell. With the best fitted physical parameters for GRB 990123 (Panaitescu & Kumar 2001) and the assumption that the parameters in the optical flash are the same as those in the afterglow, we show that: 1) the shell is thick but not thin, and we have provided the light curve for the thick shell ca...

Introduction: The formation mechanism for regions of chaotic terrain on Europa is the subject of much debate. Several models have been proposed to account for these disrupted areas of Europa's surface including melting through the ice shell by a concentrated heat source in the underlying ocean [1,2], coalescence of solid-state diapirs [3], extrusion of warm ice onto the surface [4], and melting...

Colloidosomes are aqueous cores surrounded by a shell composed of packed colloidal particles. Recent studies suggest that these colloidal shells reduce, or even inhibit, the transport of molecular species (diffusants). However, the effect of the colloidal shell on transport is unclear: In some cases, the reduction in transport of diffusants through the shell was found to be independent of the s...

Recombinant forms of the bacteriophage MS2 and its RNA-free (empty) MS2 capsid were analyzed in solution to determine if RNA content and/or the A (or maturation) protein play a role in the global arrangement of the virus protein shell. Analysis of the (coat) protein shell of recombinant versions of MS2 that lack the A protein revealed dramatic differences compared to wild-type MS2 in solution. ...
