1/f Scaling in Heart Rate Requires Antagonistic Autonomic Control
Zbigniew R. Struzik, Junichiro Hayano, Seiichiro Sakata +2
We present the first systematic evidence for the origins of 1/f-type temporal scaling in human heart rate. The heart rate is regulated by the activity of two branches of the autono…

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…

1/f Noise in a one-dimensional charge density wave system
Zbigniew R. Struzik, Andreas Glatz, Mai Suan Li
The current noise in a classical one-dimensional charge density wave system is studied in the weak pinning regime by solving the overdamped equation of motion numerically. At low t…
