Private Weakly-Random Sequences from Human Heart Rate for Quantum Amplification
Maciej Stankiewicz, Karol Horodecki, Omer Sakarya +1
We investigate whether the heart rate can be treated as a semi-random source with the aim of amplification by quantum devices. We use a semi-random source model called -Santha-V…
Visualization of short-term heart period variability with network tools as a method for quantifying autonomic drive
Danuta Makowiec, Beata Graff, Agnieszka Kaczkowska +6
Signals from heart transplant recipients can be considered to be a natural source of information for a better understanding of the impact of the autonomic nervous system on the com…
Network representation of cardiac interbeat intervals for monitoring restitution of autonomic control for heart transplant patients
Danuta Makowiec, Stanisław Kryszewski, Beata Graff +6
The aim is to present the ability of a network of transitions as a nonlinear tool providing a graphical representation of a time series. This representation is used for cardiac RR-…
Multifractal age? Multifractal analysis of cardiac interbeat intervals in assessing of healthy aging
Danuta Makowiec, Stanisaw Kryszewski, Joanna Wdowczyk-Szulc +3
24-hour Holter recordings of 124 healthy people at different age are studied. The nocturnal signals of young people reveal the presence of the multiplicative structure. This struct…
Multifractal analysis of normal RR heart-interbeat signals in power spectra ranges
Danuta Makowiec, Aleksandra Dudkowska, Rafal Galaska +1
Power spectral density is an accepted measure of heart rate variability. Two estimators of multifractal properties: Wavelet Transform Modulus Maxima and Multifractal Detrended Fluc…
Influence of stochastic delays in Seidel-Herzel model of human cardiorespiratory system
Aleksandra Dudkowska, Danuta Makowiec
Experiments that discuss influence of noise to H. Seidel and H. Herzel dynamics model of human cardiovascular system are presented. Noise is introduced by considering stochastic de…
