Euclid cms password Bregman divergences are generalizations of the well known Kullback-Leibler divergence. The We study the reliability of large networks of pulse-coupled oscillators in response to fluctuating stimuli. Specifically, we present two general solution formulae, which degenerate to the corresponding solution of the cubic NLS equation, when the quintic nonlinear term is absent. EUCLID is a proud member of the UNAI. Reliability means that a stimulus elicits essentially identical responses upon repeated presentations. In this paper it is shown that The string method is an efficent numerical method for finding transition paths and transition rates in metastable systems. Similar models are useful to study the turbulent behavior of fluids in presence of a magnetic field because of the current impossibility to handle non-regularized systems neither analytically nor via numerical simulations. We derive a critical mass threshold below which global existence is ensured. The EUCLID SG is a proud member of the IAUP. In cases when the macroscopic model is not explicity available or Communications in Mathematical Sciences. The map is built iteratively, ascending the log-likelihood of the observations, through a series of steps that move the marginal distributions along a A stochastic model for representing the missing variability in global climate models due to unresolved features of organized tropical convection is presented here. The study of this model will probably lead to a better mathematical understanding of the class of non-linear systems consisting of hyperbolic and transport equations. The major difference from the one-dimensional case is the motion of The algebraic method is developed to obtain new exact solutions, including stationary wave solutions and traveling wave solutions, for the cubic-quintic nonlinear Schrödinger (NLS) equation. Carefully using energy methods and ad hoc functional inequalities, we improve and extend previous results in this direction.

In this paper it is shown that We perform stability analysis on the finite-difference time domain method (FDTD) when extended to incorporate local space-time adaptive mesh refinement (AMR).

EUCLID is an IDB Partner The heterogenous multiscale method (HMM) is presented as a general methodology for the efficient numerical computation of problems with multiscales and multiphysics on multigrids. We present a class of “squared root metrics” based on Bregman divergences. The given threshold is thought to be the optimal High frequency solutions to partial differential equations (PDEs) are notoriously difficult to simulate numerically due to the large number of grid points required to resolve the wave oscillations. In applications, one often must rely on approximate solution methods to describe the wave field in this regime. You must register before attempting to log in. We This paper is devoted to a study of the asymptotic behavior of solutions of a chemotaxis model with logistic terms in multiple spatial dimensions.

They can be regarded as natural generalization of Euclidean distance. Of particular interest is the practically relevant case of small diffusivity, where (as in the one-dimensional case) the cell densities form plateau-like solutions for large time. We A semi-implicit formulation of the method of spectral deferred corrections (SISDC) for ordinary differential equations with both stiff and non-stiff terms is presented. The algorithm proposed performs this assignment by mapping the original variables onto a jointly-Gaussian set. EUCLID is an IDB Partner. It is expected that they are We consider a magnetohydrodynamic-α model with kinematic viscosity and magnetic diffusivity for an incompressible fluid in a three-dimensional periodic box (torus).

This type of a propagation result has since A semi-implicit formulation of the method of spectral deferred corrections (SISDC) for ordinary differential equations with both stiff and non-stiff terms is presented. We show that the Willmore functional locally decreases or increases in time in the linearly stable or unstable case respectively. The gauge freedom allows us to assign simple and specific boundary conditions for both the auxiliary field and the gauge field, thus eliminating the issue of pressure boundary condition in the usual primitive variable formulation The EUCLID SG is a proud member of the IAUP. We use a Markov chain lattice model to represent small scale convective elements which interact with each other and with the large scale environmental variables through convective available potential energy (CAPE) and middle This paper is devoted mainly to the global existence problem for the two-dimensional parabolic-parabolic Keller-Segel system in the full space. Several modifications and variations to the original spectral deferred corrections method by Dutt, Greengard, and Rokhlin concerning the choice of integration points and the form of the correction iteration are presented. The The Nordström-Vlasov system provides an interesting relativistic generalization of the Vlasov-Poisson system in the gravitational case, even though there is no direct physical application. The method relies on an efficent coupling between the macroscopic and microscopic models. Gaussian beams are asymptotically valid high frequency solutions concen- trated on a In their classical 1937 paper, Kolmogorov, Petrovsky and Piskunov proved that for a particular class of reaction-diffusion equations on the real line the solution of the initial value problem with the initial data in the form of a unit step propagates at long times with constant velocity equal to that of a certain special traveling wave solution. We will decompose the deformation tensor into the strain and rotation components and look at their distinct contributions and structures in the small strain (with respect to viscosity) dynamics.

The construction is based on the idea of the upwind We study ground, symmetric and central vortex states, as well as their energy and chemical potential diagrams, in rotating Bose-Einstein condensates (BEC) analytically and numerically. We start from the three-dimensional (3D) Gross-Pitaevskii equation (GPE) with an angular momentum rotation term, scale it to obtain a four-parameter model, reduce it to a 2D GPE in the limiting regime of strong In this paper we are interested in the finite-time stability of transition solutions of the Cahn-Hilliard equation and its connection to the Willmore functional.
