Spatiotemporal Organization of Electromechanical Phase Singularities during High-Frequency Cardiac Arrhythmias
A. Molavi Tabrizi, A. Mesgarnejad, M. Bazzi +3
Ventricular fibrillation (VF) is a lifethreatening electromechanical dysfunction of the heart associated with complex spatiotemporal dynamics of electrical excitation and mechanica…
A mechanism for electric turbulence in cardiac tissue with optogenetic modification
Rupamanjari Majumder, Sayedeh Hussaini, Vladimir S. Zykov +2
Interruptions in nonlinear wave propagation, commonly referred to as wave breaks, are typical of many complex excitable systems. In the heart they lead to fatal rhythm disorders, t…
CaosDB - Research Data Management for Complex, Changing, and Automated Research Workflows
Timm Fitschen, Alexander Schlemmer, Daniel Hornung +3
Here we present CaosDB, a Research Data Management System (RDMS) designed to ensure seamless integration of inhomogeneous data sources and repositories of legacy data. Its primary…
Mechanisms of vortices termination in the cardiac muscle
D. Hornung, V. N. Biktashev, N. F. Otani +6
We propose a solution to a long standing problem: how to terminate multiple vortices in the heart, when the locations of their cores and their critical time windows are unknown. We…
Local observability of state variables and parameters in nonlinear modeling quantified by delay reconstruction
Ulrich Parlitz, Jan Schumann-Bischoff, Stefan Luther
Features of the Jacobian matrix of the delay coordinates map are exploited for quantifying the robustness and reliability of state and parameter estimations for a given dynamical m…
Nonlinear system identification employing automatic differentiation
Jan Schumann-Bischoff, Stefan Luther, Ulrich Parlitz
An optimization based state and parameter estimation method is presented where the required Jacobian matrix of the cost function is computed via automatic differentiation. Automati…
