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…
