[HTML][HTML] Subcortical-cortical dynamical states of the human brain and their breakdown in stroke

C Favaretto, M Allegra, G Deco, NV Metcalf… - Nature …, 2022 - nature.com
The mechanisms controlling dynamical patterns in spontaneous brain activity are poorly
understood. Here, we provide evidence that cortical dynamics in the ultra-slow frequency range (…

The dimensionality and structure of species trait spaces

…, N Loiseau, M Grenié, AC Algar, M Allegra… - Ecology …, 2021 - Wiley Online Library
Trait‐based ecology aims to understand the processes that generate the overarching
diversity of organismal traits and their influence on ecosystem functioning. Achieving this goal …

Quantum brachistochrone curves as geodesics: Obtaining accurate minimum-time protocols for the control of quantum systems

X Wang, M Allegra, K Jacobs, S Lloyd, C Lupo… - Physical review …, 2015 - APS
Most methods of optimal control cannot obtain accurate time-optimal protocols. The quantum
brachistochrone equation is an exception, and has the potential to provide accurate time-…

[HTML][HTML] A low dimensional embedding of brain dynamics enhances diagnostic accuracy and behavioral prediction in stroke

S Idesis, M Allegra, J Vohryzek, Y Sanz Perl… - Scientific Reports, 2023 - nature.com
Large-scale brain networks reveal structural connections as well as functional synchronization
between distinct regions of the brain. The latter, referred to as functional connectivity (FC), …

Coherence in quantum estimation

P Giorda, M Allegra - Journal of Physics A: Mathematical and …, 2017 - iopscience.iop.org
The geometry of quantum states provides a unifying framework for estimation processes
based on quantum probes, and it establishes the ultimate bounds of the achievable precision. …

[HTML][HTML] Controlling target brain regions by optimal selection of input nodes

…, A Bertoldo, S Suweis, M Allegra - PLOS Computational …, 2024 - journals.plos.org
The network control theory framework holds great potential to inform neurostimulation
experiments aimed at inducing desired activity states in the brain. However, the current …

Quantum discord and classical correlations in the bond-charge Hubbard model: Quantum phase transitions, off-diagonal long-range order, and violation of the …

M Allegra, P Giorda, A Montorsi - Physical Review B, 2011 - APS
We study the quantum discord (QD) and the classical correlations (CC) in a reference model
for strongly correlated electrons, the one-dimensional bond-charge extended Hubbard …

[HTML][HTML] Data segmentation based on the local intrinsic dimension

M Allegra, E Facco, F Denti, A Laio, A Mira - Scientific reports, 2020 - nature.com
One of the founding paradigms of machine learning is that a small number of variables is
often sufficient to describe high-dimensional data. The minimum number of variables required …

Role of initial entanglement and non-Gaussianity in the decoherence of photon-number entangled states evolving in a noisy channel

M Allegra, P Giorda, MGA Paris - Physical review letters, 2010 - APS
We address the degradation of continuous variable (CV) entanglement in a noisy channel
focusing on the set of photon-number entangled states. We exploit several separability criteria …

[HTML][HTML] Stroke-related alterations in inter-areal communication

M Allegra, C Favaretto, N Metcalf, M Corbetta… - NeuroImage: Clinical, 2021 - Elsevier
Beyond causing local ischemia and cell damage at the site of injury, stroke strongly affects
long-range anatomical connections, perturbing the functional organization of brain networks. …
