In this work we study a modified version of the Sznajd sociophysics model. In particular we introduce reputation, a mechanism that limits the capacity of persuasion of the agents. The reputation isâ€¦ (More)

We study the surface growth generated by the random deposition of particles of different sizes. A model is proposed where the particles are aggregated on an initially flat surface, giving rise to aâ€¦ (More)

We present some results of Monte Carlo simulations for the deposition of particles of different sizes on a two-dimensional substrate. The particles are linear, height one, and can be depositedâ€¦ (More)

We propose a modification in the Sznajd sociophysics model defined on the square lattice. For this purpose, we consider reputationâ€”a mechanism limiting the agentsâ€™ persuasive power. The reputation isâ€¦ (More)

We study the competition and the evolution of nodes embedded in Euclidean restricted spaces. The population evolves by a branching process in which new nodes are generated when up to two new nodesâ€¦ (More)

Os condensados de Bose-Einstein foram previstos teoricamente nos anos de 1924-25. Contudo, sua observaÃ§Ã£o experimental sÃ³ foi obtida em 1995, laureando seus descobridores com o prÃªmio Nobel de 2001.â€¦ (More)

We study the evolution of branching trees embedded in Euclidean spaces with suppressed branching of spatially close nodes. This cooperative branching process accounts for the effect of overcrowdingâ€¦ (More)

We study an evolving tree with interacting nodes embedded into a Euclidean space. The growth of the network is generated by a branching process in which up to two new nodes are attached to a previousâ€¦ (More)
