Heterogeneous mean-field theory for two-species symbiotic processes on networks
Guilherme S. Costa, Marcelo M. de Oliveira, Silvio C. Ferreira
A simple model to study cooperation is the two-species symbiotic contact process (2SCP), in which two different species spread on a graph and interact by a reduced death rate if bo…
Effects of infection fatality ratio and social contact matrices on vaccine prioritization strategies
Arthur Schulenburg, Wesley Cota, Guilherme S. Costa +1
Effective strategies of vaccine prioritization are essential to mitigate the impacts of severe infectious diseases. We investigate the role of infection fatality ratio (IFR) and so…
Simple quasistationary method for simulations of epidemic processes with localized states
Guilherme S. Costa, Silvio C. Ferreira
Epidemic processes on random graphs or networks are marked by localization of activity that can trap the dynamics into a metastable state, confined to a subextensive part of the ne…
Outbreak diversity in epidemic waves propagating through distinct geographical scales
Guilherme S. Costa, Wesley Cota, Silvio C. Ferreira
A central feature of an emerging infectious disease in a pandemic scenario is the spread through geographical scales and the impacts on different locations according to the adopted…
Non massive immunization to contain spreading on complex networks
Guilherme S. Costa, Silvio C. Ferreira
Optimal strategies for epidemic containment are focused on dismantling the contact network through effective immunization with minimal costs. However, network fragmentation is seld…
Sampling methods for the quasistationary regime of epidemic processes on regular and complex networks
Renan S. Sander, Guilherme S. Costa, Silvio C. Ferreira
A major hurdle in the simulation of the steady state of epidemic processes is that the system will unavoidably visit an absorbing, disease-free state at sufficiently long times due…
