Addressing skepticism of the critical brain hypothesis

JM Beggs - Frontiers in computational neuroscience, 2022 - frontiersin.org
The hypothesis that living neural networks operate near a critical phase transition point has
received substantial discussion. This “criticality hypothesis” is potentially important because …

Quantifying information of intracellular signaling: progress with machine learning

Y Tang, A Hoffmann - Reports on Progress in Physics, 2022 - iopscience.iop.org
Cells convey information about their extracellular environment to their core functional
machineries. Studying the capacity of intracellular signaling pathways to transmit information …

Information propagation in multilayer systems with higher-order interactions across timescales

G Nicoletti, DM Busiello - Physical Review X, 2024 - APS
Complex systems are characterized by multiple spatial and temporal scales. A natural
framework to capture their multiscale nature is that of multilayer networks, where different …

Tuning transduction from hidden observables to optimize information harvesting

G Nicoletti, DM Busiello - Physical Review Letters, 2024 - APS
Biological and living organisms sense and process information from their surroundings,
typically having access only to a subset of external observables for a limited amount of time …

ABC transporters are billion-year-old Maxwell Demons

S Flatt, DM Busiello, S Zamuner… - Communications …, 2023 - nature.com
Abstract ATP-Binding Cassette (ABC) transporters are a broad family of biological machines,

Powerful ordered collective heat engines

FS Filho, GAL Forão, DM Busiello, B Cleuren… - Physical Review …, 2023 - APS
We introduce a class of stochastic engines in which the regime of units operating
synchronously can boost the performance. Our approach encompasses a minimal setup …

Criticality and network structure drive emergent oscillations in a stochastic whole-brain model

G Barzon, G Nicoletti, B Mariani… - Journal of Physics …, 2022 - iopscience.iop.org
Understanding the relation between the structure of brain networks and their functions is a
fundamental open question. Simple models of neural activity based on real anatomical …

Disentangling the critical signatures of neural activity

B Mariani, G Nicoletti, M Bisio, M Maschietto… - Scientific reports, 2022 - nature.com
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 …

Hyperaccurate bounds in discrete-state Markovian systems

DM Busiello, CE Fiore - Journal of Physics A: Mathematical and …, 2022 - iopscience.iop.org
Generalized empirical currents represent a vast class of thermodynamic observables of
mesoscopic systems. Their fluctuations satisfy the thermodynamic uncertainty relations …

Superconducting fluctuations and charge-4 plaquette state at strong coupling

Q Qin, JJ Dong, Y Sheng, D Huang, Y Yang - Physical Review B, 2023 - APS
We apply the static auxiliary field Monte Carlo approach to study phase correlations of the
pairing fields in a model with spin-singlet pairing interaction. We find that the short-and long …
