[...] 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.
3/3

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.
