Phenotypic heterogeneity is an important trait for the development and survival of many microorganisms including the yeast Cryptococcus spp., a deadly pathogen spread worldwide. Here, we have applied scanning electron microscopy (SEM) to defne four C

In this article we review classical and recent results in anomalous diffusion and provide mechanisms useful for the study of the fundamentals of certain processes, mainly in condensed matter physics, chemistry and biology. Emphasis will be given to s

Microbial biofilms are highly structured and dynamic communities in which phenotypic diversification allows microorganisms to adapt to different environments under distinct conditions. The environmentally ubiquitous pathogen Cryptococcus neoformans c

We study the conditions for persistent cooperation in an off-lattice model of mobile agents playing the Prisoner’s Dilemma game with pure, unconditional strategies. Each agent has an exclusion radius rp , which accounts for the population viscosity

Statistics of soccer tournament scores based on the double round robin system of several countries are studied. Exploring the dynamics of team scoring during tournament seasons from recent years we find evidences of superdiffusion. A mean-field analy

Random diffusion is shown to be an important mechanism on fostering cooperative behavior among simple agents (memoryless, unconditional cooperators or defectors) living on a spatially structured environment. In particular, under the Prisoner's Dilemm

The Prisoner’s dilemma is the main game theoretical framework in which the onset and maintainance of cooperation in biological populations is studied. In the spatial version of the model, we study the robustness of cooperation in heterogeneous ecos

A Teoria de Jogos Evolutivos oferece modelos interessantes para o estudo da emergência e manutenção da cooperação. Um mecanismo que consegue manter a cooperação no Dilema do Prisioneiro é a fixação dos jogadores em uma rede, usando dinâmic
