We perform extensive Potts model simulations of 3D dry foam coarsening and we report reaching a scaling state. Starting with 2.25million bubbles, we have enough time for the transient to end and reach the scaling state; enough time in the scaling state to characterize its properties; and finally,...

We obtain the scaling states of three-dimensional soap foams by using equilibrium statistical mechanics techniques. We consider a phase space where each bubble is characterized by its center of mass position, volume, surface and number of faces. A Gibbs entropy function is then defined and, as...

We consider learning and generalization of real functions by a multi-interacting feed-forward network model with continuous outputs with invertible transfer functions. The expansion in different multi-interacting orders provides a classification for the functions to be learnt and suggests the...

We investigate the production of Tsallis entropy for the probability distribution of random walkers on a hypercube with a fraction p of allowed sites. We consider two regimes, p=1 and from p=12 until the percolation limit pc. In the first regime, we show that the entropy rate can be obtained...

Fusion of cell tissues is an ubiquitous phenomenon and has important technological applications including tissue biofabrication. In this work we present experimental results of aggregates fusion using adipose derived stem cells (ADSC) and a three dimensional computer simulation of the process...

The influence of surface tension and size on rounding of cell aggregates is studied using chick embryonic cells and numerical simulations based on the cellular Potts model. Our results show exponential relaxation in both cases as verified in previous studies using 2D Hydra cell aggregates. The...

A major goal in post-genomic biology is the description of physiological functions in terms of gene pathway behavior. In this work, we present the first investigation of expression alterations in ninety-three pathways representing physiological functions of the plant A. thaliana induced by a P....

The proteome, a set of proteins expressed in an organism, is organized in an intricate web called the protein–protein interaction (PPI) network. In this article we propose a topological parameter called damage, that measures the consequences of the deletion of a protein from the network. We...

We present the Ontocancro Database (www.ontocancro.org) illustrated with applications to network modeling and pathway functional analysis. The database compiles information on gene pathways involved in Human Genome Maintenance Mechanisms (GMM) whose dysfunction accounts for cancer and several...

We consider an analytical approach to the Penna model with sexual reproduction. We have written evolution equations for the frequency of diseases acting at different ages and considered the special case where all mutations are deleterious and all disease alleles are dominant. In this case we...
