A bstract We study the perturbative expansion of ground state energy in presence an external field coupled to a conserved charge integrable two-dimensional O(4) nonlinear sigma model. By solving Volin’s algebraic equations for coefficients we large order asymptotic behaviour series analytically. confirm previously numerically found leading and nearest singularities Borel transformed associated ...

In this paper, a three-dimensional, single-phase proton-exchange membrane fuel cell (PEMFC) is studied numerically. Finite volume method was used for solving the governing equations and, consequently, the numerical results were validated by comparing them with experimental data, which showed good agreement. The main objective of this work is to investigate the effect of a novel gas channel shap...

This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...

This is a survey on the intermittent behavior of the parabolic Anderson model, which is the Cauchy problem for the heat equation with random potential on the lattice Z. We first introduce the model and give heuristic explanations of the long-time behavior of the solution, both in the annealed and the quenched setting for time-independent potentials. We thereby consider examples of potentials st...

MBOC described cell biology in terms of its findings— 1400 pp. $102.00 the text was full of experiments and images, including many electron micrographs, and chapters ended with references to specific journal articles as well as reviews. The presence of these experiments supported a peda-receives a coded message. Inspection of the string of gogy centered around how we know what we know numbers a...
