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…
Optimal Paths in Disordered Complex Networks
Lidia A. Braunstein, Sergey V. Buldyrev, Reuven Cohen +2
We study the optimal distance in networks, , defined as the length of the path minimizing the total weight, in the presence of disorder. Disorder is introdu…
Decomposition of Heartbeat Time Series: Scaling Analysis of the Sign Sequence
Y. Ashkenazy, P. Ch. Ivanov, S. Havlin +4
The cardiac interbeat (RR) increment time series can be decomposed into two sub-sequences: a magnitude series and a sign series. We show that the sign sequence, a simple binary rep…
Hierarchical organization of cities and nations
G. Malescio, N. V. Dokholyan, S. V. Buldyrev +1
Universality in the behavior of complex systems often reveals itself in the form of scale-invariant distributions that are essentially independent of the details of the microscopic…
