Stabilized dense emulsions display a rich phenomenology connecting microstructure and rheology. In this work we study how an emulsion with a finite yield stress can be built via large-scale stirring. By gradually increasing the volume fraction of the dispersed minority phase, under the constant… |

We present a computational method for commodity hardware-based clinical cardiovascular diagnosis based on accurate simulation of cardiovascular blood flow. Our approach leverages the flexibility of the Lattice Boltzmann method to implementation on high-performance, commodity hardware, such as… |

We prove the existence of a traveling wave solution u of the harmonic heat flow in an infinitely long cylinder of radius R, which connects two locally stable and axially symmetric steady states at + and - infinity infinity. Here u is a director field, with values in the unit sphere. The traveling… |

A classical Lotka-Volterra model with the logistical growth of prey-and-hunting coopera-
tion in the functional response of predators to prey was extended by introducing advection terms,
which included the velocities of animals. The effect of velocity on the kinetics of the problem was
analyzed. In… |

We study a nonlinear boundary value problem involving a nonlocal (integral) operator in the coefficients of the unknown function. Provided sufficient conditions for the existence and uniqueness of the solution, for its approximation, we propose a numerical method consisting of a classical… |

In the application of Pad\'{e} methods to signal
processing a basic problem is to take into account the effect of
measurement noise on the computed approximants. Qualitative
deterministic noise models have been proposed which are consistent
with experimental results. In this paper the Pad\'{e}… |

We describe the emergence of topological singularities in periodic media within the Ginzburg-Landau model and the core-radius approach. The energy functionals of both models are denoted by E, where ? represent the coherence length (in the Ginzburg-Landau model) or the core-radius size (in the core-… |
