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 present the numerical results of simulations of complex fluids under shear flow. We employ a mixed approach which combines the lattice Boltzmann method for solving the Navier-Stokes equation and a finite difference scheme for the convection-diffusion equation. The evolution in time of shear… |

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… |

More than twenty years ago the reverse vaccinology paradigm came to light trying to
design new vaccines based on the analysis of genomic information in order to select
those pathogen peptides able to trigger an immune response. In this context, focusing
on the proteome of Trypanosoma cruzi, we… |

A matrix Z ? R2n×2n is said to be in the standard symplectic form if Z enjoys a block
LU-decomposition in the sense of
A 0
-H I
Z =

, where A is nonsingular and both
G and H are symmetric and positive definite in Rn×n. Such a structure arises naturally in
the discrete algebraic Riccati… |

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-… |

Many studies have shown that Physarum polycephalum slime mold is able to find the shortest path in a maze. In this paper we study this behavior in a network, using a hyperbolic model of chemotaxis. Suitable transmission and boundary conditions at each node are considered to mimic the behavior of… |

We have developed a rat brain organotypic culture model, in which tissue slices contain cortex-subventricular zone-striatum regions, to model neuroblast activity in response to in vitro ischemia. Neuroblast activation has been described in terms of two main parameters, proliferation and migration… |
