PhysioBank, PhysioToolkit, and PhysioNet: components of a new research resource for complex physiologic signals.
TLDR
The newly inaugurated Research Resource for Complex Physiologic Signals, which was created under the auspices of the National Center for Research Resources, is intended to stimulate current research and new investigations in the study of cardiovascular and other complex biomedical signals. Expand
Multifractal Detrended Fluctuation Analysis of Nonstationary Time Series
We develop a method for the multifractal characterization of nonstationary time series, which is based on a generalization of the detrended fluctuation analysis (DFA). We relate our multifractal DFAExpand
Quantification of scaling exponents and crossover phenomena in nonstationary heartbeat time series.
TLDR
A new method--detrended fluctuation analysis (DFA)--for quantifying this correlation property in non-stationary physiological time series is described and application of this technique shows evidence for a crossover phenomenon associated with a change in short and long-range scaling exponents.

Introduction to Phase Transitions and Critical Phenomena
This is a paperback edition of a distinguished book, originally published by Clarendon Press in 1971. It was then the first text on critical phenomena, a field that has enjoyed great activity for theExpand
On the Size Distribution of Business Firms
The size distribution of business firms is explained using number and size of firms' constituent components. It is a lognormal distribution multiplied by a stretching factor which can lead to aExpand
An Introduction to Econophysics: Correlations and Complexity in Finance
TLDR
Economists and workers in the financial world will find useful the presentation of empirical analysis methods and well-formulated theoretical tools that might help describe systems composed of a huge number of interacting subsystems. Expand
Catastrophic cascade of failures in interdependent networks
TLDR
This work develops a framework for understanding the robustness of interacting networks subject to cascading failures and presents exact analytical solutions for the critical fraction of nodes that, on removal, will lead to a failure cascade and to a complete fragmentation of two interdependent networks. Expand
Fractal dynamics in physiology: Alterations with disease and aging
TLDR
Application of fractal analysis may provide new approaches to assessing cardiac risk and forecasting sudden cardiac death, as well as to monitoring the aging process, and similar approaches show promise in assessing other regulatory systems, such as human gait control in health and disease. Expand
Classes of small-world networks.
TLDR
Evidence of the occurrence of three classes of small-world networks, characterized by a vertex connectivity distribution that decays as a power law law, and the nature of such constraints may be the controlling factor for the emergence of different classes of networks are presented. Expand
