Phase transition in the Galam's majority-rule model with information-mediated independence

André L. Oestereich, Marcelo A. Pires, Silvio M. Duarte Queirós +1

We study the Galam's majority-rule model in the presence of an independent behavior that can be driven intrinsically or can be mediated by information regarding the collective opin…

Tricritical behavior in epidemic dynamics with vaccination

Marcelo A. Pires, Cesar I. N. Sampaio Filho, Hans J. Herrmann +1

We scrutinize the phenomenology arising from a minimal vaccination-epidemic (MVE) dynamics using three methods: mean-field approach, Monte Carlo simulations, and finite-size scalin…

Optimal rewiring in coupled opinion and epidemic dynamics with vaccination

Andre Oestereich, Marcelo Pires, Nuno Crokidakis +1

In this work, we study an epidemic model with vaccination coupled with opinion dynamics in a dynamic network. The network structure evolves as agents with differing opinions discon…

Double transition in kinetic exchange opinion models with activation dynamics

Marcelo A. Pires, Nuno Crokidakis

In this work we study a model of opinion dynamics considering activation/deactivation of agents. In other words, individuals are not static and can become inactive and drop out fro…

Antivax movement and epidemic spreading in the era of social networks: Nonmonotonic effects, bistability and network segregation

Marcelo A. Pires, Andre L. Oestereich, Nuno Crokidakis +1

In this work, we address a multicoupled dynamics on complex networks with tunable structural segregation. Specifically, we work on a networked epidemic spreading under a vaccinatio…

What is the potential for a second peak in the evolution of SARS-CoV-2 in emerging and developing economies? Insights from a SIRASD model considering the informal economy

Marcelo A. Pires, Nuno Crokidakis, Daniel O. Cajueiro +2

We study the potential scenarios from a Susceptible-Infected-Recovered-Asymptomatic-Symptomatic-Dead (SIRASD) model. As a novelty, we consider populations that differ in their degr…
