Coarse-grained molecular dynamics simulations are applied to explore the experimentally observed ability of the liquid-ordered (lo)/liquid-disordered (ld) phase boundary to facilitate viral membrane fusion. Surprisingly, a formed fusion stalk can be both attracted (i.e., stalkophilic) and repelled (i.e., stalkophobic) by the lo/ld phase boundary. The phase boundary becomes stalkophilic if the l...

We present a robust method for generating high-order nodal tetrahedral curved meshes. The approach consists of modifying an initial linear mesh by first, introducing high-order nodes, second, displacing the boundary nodes to ensure that they are on the CAD surface, and third, smoothing and untangling the mesh obtained after the displacement of the boundary nodes to produce a valid curved high-o...

We develop a Hermite interpolation scheme and prove error bounds forC bivariate piecewise polynomial spaces of Argyris type vanishing on the boundary of curved domains enclosed by piecewise conics.

This paper presents a fast method to avoid cracks between two adjacent NURBS-surfaces which are part of a boundary-represented 3D-object during the tessellation process. The surfaces are first divided into almost flat regions, then trimmings curves are split at the patch borders and finally intersection points are transferred to the opposite surface by using a priori connectivity information. T...

Problem of tetrahedral meshing of three-dimensional domains whose boundaries are curved surfaces is wide open. Traditional approach consists in an approximation of curved boundaries by piecewise linear boundaries before mesh generation. As the result mesh quality may deteriorate. This paper presents a technique for Delaunay-based tetrahedralization in which a set of constrained facets is formed...

An intense study of the relationship between certain quantum theories of gravity realized on curved backgrounds and suitable gauge theories, has been originated by a remarkable conjecture put forward by Maldacena almost one year ago. Among the possible curved vacua of superstring or M–theory, spaces having the form of an Anti– de Sitter space–time times a compact Einstein manifold, have been pl...
