Resonant spike propagation in coupled neurons with subthreshold activity [PDF]
, 2008 Màster en Biofísica, curs 2006-2007Chemical coupling between neurons is only active when the presynaptic neuron is firing, and thus it does not allow for the propagation of subthreshold activity.

Probing quantum information propagation with out-of-time-ordered correlators [PDF]
Nature Physics, 2021 Interacting many-body quantum systems show a rich array of physical phenomena and dynamical properties, but are notoriously difficult to study: they are analytically challenging and exponentially hard to simulate on classical computers.

Using Markov Chains to Determine Expected Propagation Time for Probabilistic Zero Forcing [PDF]
The Electronic Journal of Linear Algebra, 2019 Zero forcing is a coloring game played on a graph where each vertex is initially colored blue or white and the goal is to color all the vertices blue by repeated use of a (deterministic) color change rule starting with as few blue vertices as possible ...

Accurate online training of dynamical spiking neural networks through Forward Propagation Through Time [PDF]
Nature Machine Intelligence, 2021 Memory efficient online training of recurrent spiking neural networks without compromising accuracy is an open challenge in neuromorphic computing. Yin and colleagues demonstrate that training a recurrent neural network consisting of so-called liquid ...

Bounds on expected propagation time of probabilistic zero forcing [PDF]
European journal of combinatorics (Print), 2019 Probabilistic zero forcing is a coloring game played on a graph where the goal is to color every vertex blue starting with an initial blue vertex set. As long as the graph is connected, if at least one vertex is blue then eventually all of the vertices ...
