Reproducible biomarkers: Leveraging nonlinear descriptors in the face of non-ergodicity
Madhur Mangalam, Arash Sadri, Junichiro Hayano +3
Any reliable biomarker has to be specific, generalizable, and reproducible across individuals and contexts. The exact values of such a biomarker must represent similar health state…
Theoretical foundation of detrending methods for fluctuation analysis such as detrended fluctuation analysis and detrending moving average
Marc Höll, Ken Kiyono, Holger Kantz
We present a general framework of detrending methods of fluctuation analysis of which detrended fluctuation analysis (DFA) is one prominent example. Another more recently introduce…
Detrending Moving Average Algorithm: Frequency Response and Scaling Performances
Anna Carbone, Ken Kiyono
The Detrending Moving Average (DMA) algorithm has been widely used in its several variants for characterizing long-range correlations of random signals and sets (one-dimensional se…
Establishing a direct connection between detrended fluctuation analysis and Fourier analysis
Ken Kiyono
To understand methodological features of the detrended fluctuation analysis (DFA) using a higher-order polynomial fitting, we establish the direct connection between DFA and Fourie…
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…
Picture of the low-dimensional structure in chaotic dripping faucets
Ken Kiyono, Tomoo Katsuyama, Takuya Masunaga +1
Chaotic dynamics of the dripping faucet was investigated both experimentally and theoretically. We measured continuous change in drop position and velocity using a high-speed camer…
Taming a Chaotic Dripping Faucet via a Global Bifurcation
Ken Kiyono, Nobuko Fuchikami
We carried out a fluid dynamical simulation for a forced dripping faucet system using a new algorithm that was recently developed. The simulation shows that periodic external forci…
Dripping Faucet Dynamics Clarified by an Improved Mass-Spring Model
Ken Kiyono, Nobuko Fuchikami
An improved mass-spring model for a dripping faucet is presented. The model is constructed based on the numerical results which we recently obtained from fluid dynamical calculatio…
Simulation of a Dripping Faucet
Nobuko Fuchikami, Shunya Ishioka, Ken Kiyono
We present a simulation of a dripping faucet system. A new algorithm based on Lagrangian description is introduced. The shape of drop falling from a faucet obtained by the present…
