Scale-free networks resistant to intentional attacks
Lazaros K. Gallos, Panos Argyrakis
We study the detailed mechanism of the failure of scale-free networks under intentional attacks. Although it is generally accepted that such networks are very sensitive to targeted…
Priority diffusion model in lattices and complex networks
Michalis Maragakis, Shai Carmi, Daniel ben-Avraham +2
We introduce a model for diffusion of two classes of particles ( and ) with priority: where both species are present in the same site the motion of 's takes precedence ove…
Dynamic correlations in an ordered c(22) lattice gas
P. Argyrakis, M. Maragakis, O. Chumak +1
We obtain the dynamic correlation function of two-dimensional lattice gas with nearest-neighbor repulsion in ordered c(22) phase (antiferromagnetic ordering) under the cond…
Improving immunization strategies
Lazaros K. Gallos, Fredrik Liljeros, Panos Argyrakis +2
We introduce an immunization method where the percentage of required vaccinations for immunity are close to the optimal value of a targeted immunization scheme of highest degree no…
Evolution of Vocabulary on Scale-free and Random Networks
Alkiviadis Kalampokis, Kosmas Kosmidis, Panos Argyrakis
We examine the evolution of the vocabulary of a group of individuals (linguistic agents) on a scale-free network, using Monte Carlo simulations and assumptions from evolutionary ga…
