Solitary states in multiplex neural networks: Onset and vulnerability

L Schülen, DA Janzen, ES Medeiros… - Chaos, Solitons & …, 2021 - Elsevier
We investigate solitary states in a two-layer multiplex network of FitzHugh-Nagumo neurons
in the oscillatory regime. We demonstrate how solitary states can be induced in a multiplex …

Phase tip**: how cyclic ecosystems respond to contemporary climate

H Alkhayuon, RC Tyson… - Proceedings of the …, 2021 - royalsocietypublishing.org
We identify the phase of a cycle as a new critical factor for tip** points (critical transitions)
in cyclic systems subject to time-varying external conditions. As an example, we consider …

The activity in the brain cortex remarkably shows a simultaneous presence of robust
collective oscillations and neuronal avalanches, where intermittent bursts of pseudo …

Transient chaos enforces uncertainty in the British power grid

L Halekotte, A Vanselow, U Feudel - Journal of Physics …, 2021 - iopscience.iop.org
Multistability is a common phenomenon which naturally occurs in complex networks. If
coexisting attractors are numerous and their basins of attraction are complexly interwoven …

[HTML][HTML] Long-living transients in ecological models: Recent progress, new challenges, and open questions

A Morozov, U Feudel, A Hastings, KC Abbott… - Physics of Life …, 2024 - Elsevier
Traditionally, mathematical models in ecology placed an emphasis on asymptotic, long-term
dynamics. However, a large number of recent studies highlighted the importance of transient …

The impact of chaotic saddles on the synchronization of complex networks of discrete-time units

ES Medeiros, RO Medrano-T, IL Caldas… - Journal of Physics …, 2021 - iopscience.iop.org
A chaotic saddle is a common nonattracting chaotic set well known for generating finite-time
chaotic behavior in low and high-dimensional systems. In general, dynamical systems …

Chimera states in multiplex networks: Chameleon-like across-layer synchronization

RG Andrzejak, A Espinoso - Chaos: An Interdisciplinary Journal of …, 2023 - pubs.aip.org
Different across-layer synchronization types of chimera states in multilayer networks have
been discovered recently. We investigate possible relations between them, for example, if …
