Chaotic Scaling and Network Turbulence in Crude Oil-Equity Systems Using a Coupled Multiscale Chaos Index

International Journal of Financial Studies
Financial markets often display nonlinear and turbulent dynamics during periods of stress, and crude-oil and global equity systems frequently demonstrate closely connected forms of instability. Earlier studies report multifractality, chaotic features and

Multifractality of Pseudo-Velocities and Seismic Quiescence Associated with the Tehuantepec M8.2 EQ

Entropy, 2018
By using earthquake catalogs, previous studies have reported evidence that some changes in the spatial and temporal organization of earthquake activity are observed before and after of a main shock.

Multifractality and heart rate variability

, 2009
In this paper, we participate to the discussion set forth by the editor of Chaos for the controversy, “Is the normal heart rate chaotic?” Our objective was to debate the question, “Is there some more appropriate term to characterize the heart rate ...
