Effect of nonlinear filters on detrended fluctuation analysis
Z. Chen, K. Hu, P. Carpena +3
We investigate how various linear and nonlinear transformations affect the scaling properties of a signal, using the detrended fluctuation analysis (DFA). Specifically, we study th…
Quantification of Sleep Fragmentation Through the Analysis of Sleep-Stage Transitions
Chung-Chuan Lo, Plamen Ch. Ivanov, Lus A. Nunes Amaral +3
We introduce new quantitative approaches to study sleep-stage transitions with the goal of addressing the two following questions: (i) Can the new approaches provide more informati…
Information Entropy and Correlations in Prime Numbers
Pradeep Kumar, Plamen Ch. Ivanov, H. Eugene Stanley
The difference between two consecutive prime numbers is called the distance between the primes. We study the statistical properties of the distances and their increments (the diffe…
