Cluster-cluster aggregation with particle replication and chemotaxy: a simple model for the growth of animal cells in culture
S. G. Alves, M. L. Martins
Aggregation of animal cells in culture comprises a series of motility, collision and adhesion processes of basic relevance for tissue engineering, bioseparations, oncology research…
Strategies for Optimize Off-Lattice Aggregate Simulations
S. G. Alves, S. C. Ferreira, M. L. Martins
We review some computer algorithms for the simulation of off-lattice clusters grown from a seed, with emphasis on the diffusion-limited aggregation, ballistic aggregation and Eden…
Fighting cancer with virus
S. C. Ferreira, M. L. Martins, M. J. Vilela
One of the most promising strategies to treat cancer is attacking it with viruses. Virus can kill tumor cells specifically or act as carriers that deliver normal genes into cancer…
Electoral surveys influence on the voting processes: a cellular automata model
S. G. Alves, N. M. Oliveira Neto, M. L. Martins
Nowadays, in societies threatened by atomization, selfishness, short-term thinking, and alienation from political life, there is a renewed debate about classical questions concerni…
A reaction-diffusion model for the growth of avascular tumor
S. C. Ferreira Junior, M. L. Martins, M. J. Vilela
A nutrient-limited model for avascular cancer growth including cell proliferation, motility and death is presented. The model qualitatively reproduces commonly observed morphologie…
Roughness exponent in two-dimensional percolation, Potts and clock models
José Arnaldo Redinz, Marcelo Lobato Martins
We present a numerical study of the self-affine profiles obtained from configurations of the q-state Potts (with q=2,3 and 7) and p=10 clock models as well as from the occupation s…
Granular fingers in Hele-Shaw experiments
M. S. Couto, M. L. Martins, S. G. Alves
Granular materials constitute an intermediate state of matter between fluids and solids. Here we investigate the pattern formation when a grain is displaced by another type of grai…
A Cellular Automata Model for Citrus Variagated Chlorosis
M. L. Martins, G. Ceotto, S. G. Alves +3
A cellular automata model is proposed to analyze the progress of Citrus Variegated Chlorosis epidemics in São Paulo oranges plantation. In this model epidemiological and environmen…
