Self-consistent stochastic dynamics for finite-size networks of spiking neurons

no code implementations29 Dec 2021 Gianni V. Vinci, Roberto Benzi, Maurizio Mattia

Despite the huge number of neurons composing a brain network, ongoing activity of local cell assemblies composing cortical columns is intrinsically stochastic.

Spatial population genetics with fluid flow

no code implementations16 Dec 2021 Roberto Benzi, David R. Nelson, Suraj Shankar, Federico Toschi, Xiaojue Zhu

The growth and evolution of microbial populations is often subjected to advection by fluid flows in spatially extended environments, with immediate consequences for questions of spatial population genetics in marine ecology, planktonic diversity and origin of life scenarios.

Deep learning velocity signals allows to quantify turbulence intensity

no code implementations13 Nov 2019 Alessandro Corbetta, Vlado Menkovski, Roberto Benzi, Federico Toschi

Turbulence, the ubiquitous and chaotic state of fluid motions, is characterized by strong and statistically non-trivial fluctuations of the velocity field, over a wide range of length- and time-scales, and it can be quantitatively described only in terms of statistical averages.

The collective effect of finite-sized inhomogeneities on the spatial spread of populations in two dimensions

1 code implementation11 Oct 2019 Wolfram Möbius, Francesca Tesser, Kim M. J. Alards, Roberto Benzi, David R. Nelson, Federico Toschi

In a regime where front dynamics is determined by a local front speed only, a principle of least time can be employed to predict front speed and shape.
