Multiscaling comparative analysis of time series and geophysical phenomena
Nicola Scafetta, Bruce J. West
Different methods are used to determine the scaling exponents associated with a time series describing a complex dynamical process, such as those observed in geophysical systems. M…
Phase synchronization in cerebral hemodynamics
Miroslaw Latka, Malgorzata Turalska, Waldemar Kolodziej +3
A healthy human brain is perfused with blood flowing laminarly through cerebral vessels, providing brain tissue with substrates such as oxygen and glucose. Under normal conditions,…
Deterministic uncertainty
Bartosz Telenczuk, Miroslaw Latka, Bruce J. West
Equations of motion with delays naturally emerge in the analysis of complex biological control systems which are organized around biochemically mediated feedback interactions. We s…
Influence of progressive central hypovolemia on multifractal dimension of cardiac interbeat intervals
Bruce J. West, Nicola Scafetta, William H. Cooke +1
We analyzed the heartbeat time series of 12 human subjects exposed to progressive central hypovolemia with lower body negative pressure. Two data processing techniques based on wav…
Non-extensive diffusion entropy analysis: non-stationarity in teen birth phenomena
N. Scafetta, P. Grigolini, P. Hamilton +1
A complex process is often a balance between non-stationary and stationary components. We show how the non-extensive Tsallis q-entropy indicator may be interpreted as a measure of…
The Loss of Multifractality in Migraines
Miroslaw Latka, Marta Glaubic-Latka, Dariusz Latka +1
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). The time series of the axial flow velocity averaged over…
