CompuCell3D Model of Cell Migration Reproduces Chemotaxis
Pedro C. Dal-Castel, Gilberto L. Thomas, Gabriel C. Perrone +1
Chemotaxis combines three processes: directional sensing, polarity reorientation and migration. Directed migration plays an important role in immune response, metastasis, wound hea…
Velocities of Mesenchymal Cells May be Ill-Defined
Guilherme S. Y. Giardini, Gilberto L. Thomas, Carlo R. da Cunha +1
The dynamics of single cell migration on flat surfaces is usually modeled by a Langevin-like problem consisting of ballistic motion for short periods and random walk. for long peri…
Shape-velocity correlation defines polarization in migrating cell simulations
Gilberto L. Thomas, Ismael Fortuna, Gabriel C. Perrone +2
Cell migration plays essential roles in development, wound healing, diseases, and in the maintenance of a complex body. Experiments in collective cell migration generally measure q…
Exact solution for the Anisotropic Ornstein-Uhlenbeck Process
Rita M. C. de Almeida, Guilherme S. Y. Giardini, Mendeli Vainstein +2
Active Matter models commonly consider particles with overdamped dynamics subject to a force (speed) with constant modulus and random direction. Some models include also random noi…
Master equation for the degree distribution of a Duplication and Divergence network
Vítor Sudbrack, Leonardo G. Brunnet, Rita M. C. de Almeida +2
Network growth as described by the Duplication-Divergence model proposes a simple general idea for the evolution dynamics of natural networks. In particular it is an alternative to…
Topological Order from a Cohomological and Higher Gauge Theory perspective
R. Costa de Almeida, J. P. Ibieta-Jimenez, J. Lorca Espiro +1
In recent years, attempts to generalize lattice gauge theories to model topological order have been carried out through the so called -gauge theories. These have opened the door…
Analytic solutions for links and triangles distributions in finite Barabási-Albert networks
Ricardo M. Ferreira, Rita M. C. de Almeida, Leonardo G. Brunnet
Barabási-Albert model describes many different natural networks, often yielding sensible explanations to the subjacent dynamics. However, finite size effects may prevent from disce…
3D simulations of wet foam coarsening evidence a self similar growth regime
Gilberto L. Thomas, Julio M. Belmonte, François Graner +2
In wet liquid foams, slow diffusion of gas through bubble walls changes bubble pressure, volume and wall curvature. Large bubbles grow at the expenses of smaller ones. The smaller…
Growth laws and self-similar growth regimes of coarsening two-dimensional foams: Transition from dry to wet limits
Ismael Fortuna, Gilberto L. Thomas, Rita M. C. de Almeida +1
We study the topology and geometry of two dimensional coarsening foams with arbitrary liquid fraction. To interpolate between the dry limit described by von Neumann's law, and the…
Entropy and equilibrium state of free market models
J. R. Iglesias, R. M. C. de Almeida
Many recent models of trade dynamics use the simple idea of wealth exchanges among economic agents in order to obtain a stable or equilibrium distribution of wealth among the agent…
Scaling in a continuous time model for biological aging
R. M. C. de Almeida, G. L. Thomas
In this paper we consider a generalization to the asexual version of the Penna model for biological aging, where we take a continuous time limit. The genotype associated to each in…
Stretched Exponential Relaxation on the Hypercube and the Glass Transition
R. M. C. de Almeida, N. Lemke, I. A. Campbell
We study random walks on the dilute hypercube using an exact enumeration Master equation technique, which is much more efficient than Monte Carlo methods for this problem. For each…
Theoretical approach to biological aging
R. M. C. de Almeida, S. Moss de Oliveira, T. J. P. Penna
We present a model for biological aging that considers the number of individuals whose (inherited) genetic charge determines the maximum age for death: each individual may die befo…
Neural networks with high order connections
J. J. Arenzon, R. M. C. de Almeida
We present results for two different kinds of high order connections between neurons acting as corrections to the Hopfield model. Equilibrium properties are analyzed using the repl…
