Globally chaotic analysis of Heart Rate Variability during acute auditory stimulus by heavy metal music
(Mavera Edições Técnicas e Científicas Ltda, 2015-10-01)
OBJECTIVE: Auditory stimulation with relaxing style music can improve cardiac autonomic regulation in subjects treated with a cardio-toxic medication. We assess the acute effect of heavy metal music on cardiac autonomic ...
Nonlinear dynamics of heart rate during slow breathing exercise
(2018-04-01)
The acute effects of slow breathing exercises on the complex behaviour of heart rate regulation were investigated. We evaluated 21 healthy male volunteers aged between 18 and 30 years old. Heart rate variability was ...
Seeking a fingerprint: analysis of point processes in actigraphy recording
(IOP Publishing, 2016-05)
Motor activity of humans displays complex temporal fluctuations which can be characterised by scale-invariant statistics, thus demonstrating that structure and fluctuations of such kinetics remain similar over a broad range ...
Analysis of Time Dynamical Features in Intraplate Versus Interplate Seismicity: The Case Study of Iquique Area (Chile)
(Springer, 2020)
The intraplate and interplate seismic catalogues of Iquique (Chile) area were investigated by using seismological (bvalue of the Gutenberg-Richter law), fractal (Allan Factor and detrended fluctuation analysis) and topological ...
Fluctuations in Richness and Abundance of Social Wasps During the Dry and Wet Seasons in Three Phyto-Physiognomies at the Tropical Dry Forest of Brazil
(Entomological Soc Amer, 2009-12-01)
The social wasp nests were quantified in three different plant physiognomies (forested Caatinga, shrubby Caatinga, and agricultural systems) to analyze the effect of environmental seasonality and plant physiognomy on the ...

Validity of detrended fluctuation analysis of heart rate variability to determine intensity thresholds in elite cyclists
(Taylor and Francis Ltd.United Kingdom, 2022)
Self-affine analysis of protein energy
(2010)
We study the time series of the total energy of polypeptides and proteins. These time series were generated by molecular dynamics methods and analyzed by applying detrended
fluctuation analysis to estimate the long-range ...
Fractal dynamics of heart rate variability for short term
(2014)
The fractal analysis of heart rate variability (HRV) has been associated to the chaos theory. We evaluated the association of the fractal exponents of HRV with the time and frequency domain and geometric indices of HRV for ...
