Quantification of Sleep Fragmentation Through the Analysis of Sleep-Stage Transitions
Chung-Chuan Lo, Plamen Ch. Ivanov, Lus A. Nunes Amaral +3
We introduce new quantitative approaches to study sleep-stage transitions with the goal of addressing the two following questions: (i) Can the new approaches provide more informati…
Relation between Magnitude Series Correlations and Multifractal Spectrum Width
Yosef Ashkenazy, Shlomo Havlin, Plamen Ch. Ivanov +3
We study the correlation properties of long-range correlated time series, , with tunable correlation exponent and built-in multifractal properties. For the cases we investigat…
Quantitative Characterization of Permeability Fluctuations in Sandstone
Hernán A. Makse, Glenn W. Davies, Shlomo Havlin +3
Sedimentary rocks have complicated permeability fluctuations arising from the geological processes that formed them. These permeability fluctuations significantly affect the flow o…
