Critical Scale-invariance in Healthy Human Heart Rate
Ken Kiyono, Zbigniew R. Struzik, Naoko Aoyagi +3
We demonstrate the robust scale-invariance in the probability density function (PDF) of detrended healthy human heart rate increments, which is preserved not only in a quiescent co…
Power-law temporal auto-correlations in day-long records of human physical activity and their alteration with disease
Luis A. Nunes Amaral, Danyel J. Bezerra Soares, Luciano R. da Silva +5
We investigate long-duration time series of human physical activity under three different conditions: healthy individuals in (i) a constant routine protocol and (ii) in regular dai…
Behavioral-Independent Features of Complex Heartbeat Dynamics
Luis A. Nunes Amaral, Plamen Ch. Ivanov, Naoko Aoyagi +5
We test whether the complexity of cardiac interbeat interval time series is simply a consequence of the wide range of scales characterizing human behavior, especially physical acti…
