Detecting seizure onset and offset times using human intelligence: A critical-transitions-based approach
Andrew Flynn, Cian McCafferty, Klaus Lehnertz +4
Most existing seizure detection algorithms require extensive pre-processing of the data and rely on heuristic or currently unexplainable machine learning approaches. These approach…
Complex network topological and spectral determinants of extreme events
Christian Hechler, Timo Bröhl, Ulrike Feudel +1
We study the impact of the coupling topology on the ability of various networked dynamical systems to generate extreme events. By determining the coupling strength that is necessar…
Transcript-based estimators for characterizing interactions
Manuel Adams, José M. Amigó, Klaus Lehnertz
The concept of transcripts was introduced in 2009 as a means to characterize various aspects of the functional relationship between time series of interacting systems. Based on thi…
Quantifying the irregularity of a time series
Max Potratzki, Manuel Adams, Timo Bröhl +1
We introduce circulance, a scalar measure for classifying time series of dynamical systems. Circulance captures the extent of temporal regularity or irregularity that is encoded in…
Classifying absence seizure generation mechanisms: A critical transitions framework
Andrew Flynn, Cian McCafferty, Klaus Lehnertz +4
Understanding how the brain switches from normal activity to an epileptic seizure is essential for improving seizure therapy, yet the underlying seizure generation mechanisms remai…
Discontinuous stochastic forcing in Greenland ice core data
Keno Riechers, Andreas Morr, Klaus Lehnertz +4
Paleoclimate proxy records from Greenland ice cores, archiving e.g. O as a proxy for surface temperature, show that sudden climatic shifts called Dansgaard-Oeschger events…
Generalized synchronization in the presence of dynamical noise and its detection via recurrent neural networks
José M. Amigó, Roberto Dale, Juan C. King +1
Given two unidirectionally coupled nonlinear systems, we speak of generalized synchronization when the responder \textquotedblleft follows\textquotedblright\ the driver. Mathematic…
Time-series-analysis-based detection of critical transitions in real-world non-autonomous systems
Klaus Lehnertz
Real-world non-autonomous systems are open, out-of-equilibrium systems that evolve in and are driven by temporally varying environments. Such systems can show multiple timescale an…
Synchronization dynamics of phase oscillators on power grid models
Max Potratzki, Timo Bröhl, Thorsten Rings +1
We investigate topological and spectral properties of models of European and US-American power grids and of paradigmatic network models as well as their implications for the synchr…
