Data-driven analysis of annual rain distributions
Yosef Ashkenazy, Naftali R. Smith
Rainfall is an important component of the climate system and its statistical properties are vital for prediction purposes. In this study, we have developed a statistical method for…
Scale Specific and Scale Independent Measures of Heart Rate Variability as Risk Indicators
Y. Ashkenazy, M. Lewkowicz, J. Levitan +7
We study the Heart Rate Variability (HRV) using scale specific variance and scaling exponents as measures of healthy and cardiac impaired individuals. Our results show that the var…
Complexity, Tunneling and Geometrical Symmetry
L. P. Horwitz, J. Levitan, Y. Ashkenazy
It is demonstrated in the context of the simple one-dimensional example of a barrier in an infinite well, that highly complex behavior of the time evolution of a wave function is a…
Chaotic Signatures in the Spectrum of a Quantum Double Well
R. Berkovits, Y. Ashkenazy, L. P. Horwitz +1
The spectrum of a double well constructed of a square barrier embedded in an infinite well is analyzed. Level statistics for levels slightly above the barrier show signs of Wigner…
The Necessity for a Time Local Dimension in Systems with Time Varying Attractors
K. Saermark, Y. Ashkenazy, J. Levitan +1
We show that a simple non-linear system of ordinary differential equations may possess a time varying attractor dimension. This indicates that it is infeasible to characterize EEG…
