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…
Analysis, Synthesis, and Estimation of Fractal-Rate Stochastic Point Processes
Stefan Thurner, Steven B. Lowen, Markus C. Feurstein +3
Fractal and fractal-rate stochastic point processes (FSPPs and FRSPPs) provide useful models for describing a broad range of diverse phenomena, including electron transport in amor…
Conservation laws in coupled multiplicative random arrays lead to noise
Stefan Thurner, Markus C. Feurstein, Malvin C. Teich
We consider the dynamic evolution of a coupled array of N multiplicative random variables. The magnitude of each is constrained by a lower bound w_0 and their sum is conserved. Ana…
