In this paper, the boundary-based estimation of pressure distribution in the cardiovascular system is investigated using two dimensional flow images. The conventional methods of non-invasive estimation of pressure distribution in the cardiovascular flow domain use the differential form of governing equations. This study evaluates the advantages of using the integral form of the equations in the...

We study the evolution of cosmological domain walls in models with asymmetric potentials. Our research goes beyond standard case spontaneous breaking an approximate symmetry. When symmetry is explicitly broken potential exhibits nearly degenerate minima which can lead to creation a metastable network walls. The time after will decay depends on difference values minima, its asymmetry around maxi...

Linear systems with large differences between the coefficients, called ‘‘discontinuous coefficients’’, often arise when physical phenomena in heterogeneous media are modeled by partial differential equations (PDEs). Such problems are usually solved by domain decomposition techniques, but these can be difficult to implement when subdomain boundaries are complicated or the grid is unstructured. I...

The cold-active phosphoglycerate kinase from the Antarctic bacterium Pseudomonas sp. TACII18 exhibits two distinct stability domains in the free, open conformation. It is shown that these stability domains do not match the structural N- and C-domains as the heat-stable domain corresponds to about 80 residues of the C-domain, including the nucleotide binding site, whereas the remaining of the pr...
