Receiver-Operating-Characteristic Analysis Reveals Superiority of Scale-Dependent Wavelet and Spectral Measures for Assessing Cardiac Dysfunction
Stefan Thurner, Markus C. Feurstein, Steven B. Lowen +1
Receiver-operating-characteristic (ROC) analysis was used to assess the suitability of various heart rate variability (HRV) measures for correctly classifying electrocardiogram rec…
ROC Analysis and a Realistic Model of Heart Rate Variability
Stefan Thurner, Markus C. Feurstein, Malvin C. Teich
We have carried out a pilot study on a standard collection of electrocardiograms from patients who suffer from congestive heart failure, and subjects without cardiac pathology, usi…
Multiresolution wavelet analysis of heartbeat intervals discriminates healthy patients from those with cardiac pathology
Stefan Thurner, Markus C. Feurstein, Malvin C. Teich
We applied multiresolution wavelet analysis to the sequence of times between human heartbeats (R-R intervals) and have found a scale window, between 16 and 32 heartbeats, over whic…
Chaotic behavior of confining lattice gauge field configurations
Tamas S. Biro, Markus Feurstein, Harald Markum
We analyze the leading Lyapunov exponents of SU(2) Yang-Mills field configurations on the lattice which are initialized by quantum Monte Carlo simulations. We find that configurati…
Visualization of topological objects in the deconfinement phase of pure QCD
Markus Feurstein, Harald Markum, Stefan Thurner
In the last years it turned out that instantons and monopoles have a certain local correlation in four-dimensional QCD. It was demonstrated by several groups independently and by d…
Visualization of topological structure and chiral condensate
Markus Feurstein, Harald Markum, Stefan Thurner
We perform a mutual analysis of the topological and chiral vacuum structure of four-dimensional QCD on the lattice at finite temperature. We demonstrate that at the places where in…
