Scaling of optimal-path-lengths distribution in complex networks
Tomer Kalisk, Lidia A. Braunstein, Sergey V. Buldyrev +2
We study the distribution of optimal path lengths in random graphs with random weights associated with each link (``disorder''). With each link we associate a weight $τ_i = \ex…
Scaling Phenomena in the Growth Dynamics of Scientific Output
Kaushik Matia, Luis A. Nunes Amaral, Marc Luwel +2
We analyze a set of three databases at different levels of aggregation (i) a database of approximately publications of 247 countries in the period between 1980--2001. (ii) A…
A Generalized Preferential Attachment Model for Complex Systems
Kazuko Yamasaki, Kaushik Matia, Dongfeng Fu +4
Complex systems can be characterized by classes of equivalency of their elements defined according to system specific rules. We propose a generalized preferential attachment model…
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…
Universal Mechanisms in the Growth of Voluntary Organizations
Fredrik Liljeros, Luis A Nunes Amaral, H. Eugene Stanley
We analyze the growth statistics of Swedish trade unions and find a universal functional form for the probability distribution of growth rates of union size, and a power law depend…
