  An Infinite Resources Consumer-Resource Model, Descrição: Coexistence of different species in a given environment has been an important subject for ecologists over many years. The Competitive Exclusion Principle sets a theoretical limit for the number of coexisting species which is not always satisfied by real communities (e.g. the Plankton Paradox). The problem of coexistence finds its analytical background on the so-called Consumer Resource models, a class of mathematical models that describe the ecological interaction between nutrients (resources) and a biological community (consumers). In this project, we study a version in which the number of resources is unbounded, meaning that new niches can be discovered due to mutations, setting the model we introduce an example of an Eco-Evo dynamics. We investigate under which conditions the number of consumed resources and the number of species can reach an equilibrium value, posing the existence of two phases, one with increasing diversity and another with limited diversity.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Vitor Marquioni Monteiro - Coordenador / DE AGUIAR, MARCUS A.

  Computing the genetic variability of a RNA virus going on epidemic, Descrição: The COVID-19 pandemic forced governments to implement non-pharmacological measures, such as quarantine, lockdown and mandatory use of masks, in order to contain the viral propagation. Understanding the patterns of an epidemic is essential for decision-makers and a great effort has been made for modelling the routes of the ongoing pandemic, as also for developing medical treatments and vaccines. However, SARS-CoV-2 kept evolving while spreading, giving birth to different strains which are now escaping from the immune system of already immunized individuals, originating new waves of infection. Thus, tracking the genome variability is substantial for controlling the spread. In this work, we describe a model of viral propagation through contact networks which keeps tracking the viral genome of a RNA virus such as SARS-CoV-2. By including a binary chain describing the genetic material and allowing neutral mutations to happen at any locus, we aim to investigate how different contact network structures could shape the viral diversity.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Vitor Marquioni Monteiro - Integrante / Marcus A.

  Phase transitions in finite Derrida-Higgs models, Descrição: The Derrida-Higgs model is a populaton dynamics model which leads to sympatric speciation. When the number of gene loci is infinite, there is an analytical well known transition point. However, for finite genomes, this point is not known. Finding the analytical solution for this model when the genome is finite is the aim of this project.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Vitor Marquioni Monteiro - Coordenador / Marcus A.

  N-Dimensional Generalization of the Elephant Random Walk, Descrição: The Elephant Random Walk model is a non-markovian, one-dimensional and discrete time and space random walk that has a long range memory mechanism. The purpose of this project is to stablish a suitable generalization to N-dimensions, coupling the memory among all directions, in order to answer the question "what if an elephant remembers also the past of another elephant".. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Mestrado acadêmico: (1) . , Integrantes: Vitor Marquioni Monteiro - Coordenador / Leonardo Paulo Maia - Integrante.

  Phase Reduction of Stochastic Limit Cycle Oscillators, Descrição: Limit Cycles are isolated and closed trajectories in the phase space, important in describing the self-sustained oscillations characteristic of many natural and artificial systems, such as nerve cells and chemical reactions. Phase Reduction is a standard procedure of dimension reduction, in which the full dynamics is projected onto an attracting limit cycle, disregarding the distance between the trajectory and the cycle. This method is widely used in deterministic equations but that raises conceptual difficulties when applied to stochastic equations. In this project we study some definitions of the phase variable in stochastic systems attempting to find a quite general phase equation to stochastic equations.. , Situação: Desativado; Natureza: Pesquisa. , Alunos envolvidos: Mestrado acadêmico: (1) . , Integrantes: Vitor Marquioni Monteiro - Coordenador / Leonardo Paulo Maia - Integrante.
