Optimal information gain at the onset of habituation to repeated stimuli
Giorgio Nicoletti, Matteo Bruzzone, Samir Suweis +2
Biological and living systems process information across spatiotemporal scales, exhibiting the hallmark ability to constantly modulate their behavior to ever-changing and complex e…
The emergence of scale-free fires in Australia
Giorgio Nicoletti, Leonardo Saravia, Fernando Momo +2
Between 2019 and 2020, during the country's hottest and driest year on record, Australia experienced a dramatic bushfire season, with catastrophic ecological and environmental cons…
Disentangling the critical signatures of neural activity
Benedetta Mariani, Giorgio Nicoletti, Marta Bisio +3
The critical brain hypothesis has emerged as an attractive framework to understand neuronal activity, but it is still widely debated. In this work, we analyze data from a multi-ele…
Testing the critical brain hypothesis using a phenomelogical renormalization group
Giorgio Nicoletti, Samir Suweis, Amos Maritan
We present a systematic study to test a recently introduced phenomenological renormalization group, proposed to coarse-grain data of neural activity from their correlation matrix.…
Information-based fitness and the emergence of criticality in living systems
Jorge Hidalgo, Jacopo Grilli, Samir Suweis +3
Empirical evidence suggesting that living systems might operate in the vicinity of critical points, at the borderline between order and disorder, has proliferated in recent years,…
Prescription-induced jump distributions in multiplicative Poisson processes
Samir Suweis, Amilcare Porporato, Andrea Rinaldo +1
Generalized Langevin equations (GLE) with multiplicative white Poisson noise pose the usual prescription dilemma leading to different evolution equations (master equations) for the…
