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

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