[...] which are a two-dimensional map and the FitzHugh-Nagumo neuron model. The results show that in both cases, the system can be self-tuned to its bifurcation point by modifying the control parameter according to the first coefficient of the autocorrelation function.

This work is part of a collaboration between GISC and CEMSC³ - Argentina. In this publication, the authors present numerical evidence that the dynamics of a single neuron can be controlled in the vicinity of its bifurcation point. The approach is tested in two models, [...]

[...] depending on the nature of those couplings. In particular, a controversy-seeking mechanism, in which agents are stimulated to postpone their transitions to the stiffer state upon interactions with other agents of confronting opinions, enhances the rumor spreading.

The authors reported that a highly modular topology of polarized networks strongly impairs rumor spreading, but the couplings between agents’ opinions and their spreading/stifling rates can either further inhibit or, conversely, foster information propagation, [...]

This effort had not only a scientific/academic impact but also a social one since the group was a reliable source for the press and UFV in the decision-making process during the pandemic. More information is available at youtube.com/watch?v=kns4... .

They considered the epidemic of COVID-19 in Brazil by performing data-driven simulations. The results are published in the paper “Outbreak diversity in epidemic waves propagating through distinct geographical scales” in Physical Review Research, available at doi.org/10.1103/Phys....

Guilherme S. Costa, @wcota.me, and @silviojrufv.bsky.social used time series of reported cases of COVID-19 in Brazil (covid19br.wcota.me/en/) and human mobility data to simulate qualitative scenarios at a municipality level.
