The heart-rate dynamics are one of the most analyzed physiological interactions. Many
mathematical methods were proposed to evaluate heart-rate variability. These methods …

Data series generated by complex systems exhibit fluctuations on many time scales and/or
broad distributions of the values. In both equilibrium and non-equilibrium situations, the …

It has been suggested that human behavior in general and cognitive performance in
particular emerge from coordination between multiple temporal scales. In this article, we …

In this paper, the multifractality degree in a collection of developed and emerging stock
market indices is evaluated. Empirical results suggest that the multifractality degree can be …

We perform a systematic investigation on the components of the empirical multifractality of
financial returns using the daily data of Dow Jones Industrial Average from 26 May 1896 to …

Many physical and physiological signals exhibit complex scale-invariant features
characterized by 1/f scaling and long-range power-law correlations, indicating a possibly …

We analyze the sequence of time intervals between consecutive stock trades of thirty
companies representing eight sectors of the US economy over a period of 4 yrs. For all …

Evidence of past climate variations are stored in polar ice caps and indicate glacial‐
interglacial cycles of∼ 100 kyr. Using advanced scaling techniques we study the long …

In this paper multifractal detrended fluctuation analysis (MFDFA) is used to study the human
gait time series for normal and diseased sets. It is observed that long range correlation is …

We use some fractal analysis methods to study river flow fluctuations. The result of the
Multifractal Detrended Fluctuation Analysis (MF-DFA) shows that there are two crossover …
