Fractal correlation property of heart rate variability in response to the postural change maneuver in healthy women
(2014-05-15)
Background: We evaluated the effects of the PCM on the fractal analysis of the HRV in healthy women. Method. We evaluated healthy women between 18 and 30 years old. HRV was analyzed in the time (SDNN, RMSSD, NN50 and pNN50) ...
Fractal scaling exponents of heart rate variability association with linear indices and Poincaré Plot: Original article
(2014-01-01)
The literature indicated that the fractal analysis of heart rate variability (HRV) is related to the chaos theory. However, it is not clear if the both short and long-term fractal scaling exponents of HRV are reliable for ...

Some stylized facts of the Bitcoin market
(Elsevier Science, 2017-10)
In recent years a new type of tradable assets appeared, generically known as cryptocurrencies. Among them, the most widespread is Bitcoin. Given its novelty, this paper investigates some statistical properties of the Bitcoin ...
Complexity of human postural control in young and older adults during prolonged standing
(SPRINGER, 2008)
Aging is known to have a degrading influence on many structures and functions of the human sensorimotor system. The present work assessed aging-related changes in postural sway using fractal and complexity measures of the ...
