Measuring chaos in the Lorenz and Rössler models: Fidelity tests for reservoir computing
James Scully, Alexander Neiman, Andrey Shilnikov
This study is focused on the qualitative and quantitative characterization of chaotic systems with the use of symbolic description. We consider two famous systems: Lorenz and Rössl…
Demixing of two species via reciprocally concentration-dependent diffusivity
Lutz Schimansky-Geier, Benjamin Lindner, Sebastian Milster +1
We propose a model for demixing of two species by assuming a density-dependent effective diffusion coefficient of the particles. Both sorts of microswimmers diffuse as active overd…
Vocal wow in an adapted reflex resonance model
François-Xavier Brajot, Alexander B Neiman
Vocal wow is a slow 0.2 - 3 Hz modulation of the voice that may be distinguished from the 4 - 7 Hz modulation of tremor or vibrato. We use a simple model of laryngeal muscle activa…
Variability of collective dynamics in random tree networks of strongly-coupled stochastic excitable elements
Ali Khaledi-Nasab, Justus A. Kromer, Lutz Schimansky-Geier +1
We study the collective dynamics of strongly diffusively coupled excitable elements on small random tree networks. Stochastic external inputs are applied to the leaves causing larg…
Bottom-up approach to torus bifurcation in neuron models
Huiwen Ju, Alexander Neiman, Andrey Shilnikov
We study the quasi-periodicity phenomena occurring at the transition between tonic spiking and bursting activities in exemplary biologically plausible Hodgkin-Huxley type models of…
Emergent stochastic oscillations and signal detection in tree networks of excitable elements
Justus Kromer, Ali Khaledi-Nasab, Lutz Schimansky-Geier +1
We study the stochastic dynamics of strongly-coupled excitable elements on a tree network. The peripheral nodes receive independent random inputs which may induce large spiking eve…
