The close phylogenetic relationship between humans and nonhuman primates, coupled
with the exponential expansion of human populations and human activities within primate …

We develop a method for the multifractal characterization of nonstationary time series, which
is based on a generalization of the detrended fluctuation analysis (DFA). We relate our …

While the incorporation of mathematical and engineering methods has greatly advanced in
other areas of the life sciences, they have been under-utilized in the field of animal welfare …

Detrended fluctuation analysis (DFA) is a scaling analysis method used to estimate long-
range power-law correlation exponents in noisy signals. Many noisy signals in real systems …

A major issue in financial economics is the behavior of asset returns over long horizons.
Various estimators of long-range dependence have been proposed. Even though some …

We use multifractal detrended fluctuation analysis (MF-DFA), to study sunspot number
fluctuations. The result of the MF-DFA shows that there are three crossover timescales in the …

Multifractal detrended fluctuation analysis (MFDFA) has become a central method to
characterise the variability and uncertainty in empiric time series. Extracting the fluctuations …

Ecologists sometimes have a less-than-rigorous background in quantitative methods, yet
research within this broad field is becoming increasingly mathematical. Written in a step-by …

We study correlation properties of the magnitude and the sign of the increments in the time
intervals between successive heartbeats during light sleep, deep sleep, and rapid eye …

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 …
