Nonlinear Barabási-Albert Network
R. N. Onody, P. A. de Castro
In recent years there has been considerable interest in the structure and dynamics of complex networks. One of the most studied networks is the linear Barabási-Albert model. Here w…
The Branched Polymer Growth Model Revisited
Ubiraci P. C. Neves, Andre L. Botelho, Roberto N. Onody
The Branched Polymer Growth Model (BPGM) has been employed to study the kinetic growth of ramified polymers in the presence of impurities. In this article, the BPGM is revisited on…
Optimization and self-organized criticality in a magnetic system
R. N. Onody, P. A. de Castro
We propose a kind of Bak-Sneppen dynamics as a general optimization technique to treat magnetic systems. The resulting dynamics shows self-organized criticality with power law scal…
The Heumann-Hotzel model for aging revisited
Nazareno G. F. de Medeiros, Roberto N. Onody
Since its proposition in 1995, the Heumann-Hotzel model has remained as an obscure model of biological aging. The main arguments used against it were its apparent inability to desc…
Time evolution of the Partridge-Barton Model
Roberto N. Onody, Nazareno G. F. de Medeiros
The time evolution of the Partridge-Barton model in the presence of the pleiotropic constraint and deleterious somatic mutations is exactly solved for arbitrary fecundity in the co…
The N-steps Invasion Percolation Model
Reginaldo A. Zara, Roberto N. Onody
A new kind of invasion percolation is introduced in order to take into account the inertia of the invader fluid. The inertia strength is controlled by the number N of pores (or ste…
The Optimized Model of Multiple Invasion Percolation
R. A. Zara, R. N. Onody
We study the optimized version of the multiple invasion percolation model. Some topological aspects as the behavior of the acceptance profile, coordination number and vertex type a…
Ac transport studies in polymers by a resistor network and transfer matrix approaches: application to polyaniline
H. N. Nagashima, R. N. Onody, R. M. Faria
A statistical model of resistor network is proposed to describe a polymer structure and to simulate the real and imaginary components of its ac resistivity. It takes into account t…
Cluster, backbone and elastic backbone structures of the multiple invasion percolation
R. N. Onody, R. A. Zara
We study the cluster, the backbone and the elastic backbone structures of the multiple invasion percolation for both the perimeter and the optimized versions. We investigate the be…
