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.

Components of multifractality in the Central England Temperature anomaly series

, 2013
We study the multifractal nature of the Central England Temperature (CET) anomaly, a time series that spans more than 200 years. The series is analyzed as a complete data set and considering a sliding window of 11 years.

Logarithmic Coefficients and Generalized Multifractality of Whole-Plane SLE

, 2017
We consider the whole-plane SLE conformal map f from the unit disk to the slit plane, and show that its mixed moments, involving a power p of the derivative modulus |f'| and a power q of the map |f| itself, have closed forms along some integrability ...

Long range correlation in cosmic microwave background radiation

, 2011
We investigate the statistical anisotropy and Gaussianity of temperature fluctuations of Cosmic Microwave Background radiation (CMB) data from {\it Wilkinson Microwave Anisotropy Probe} survey, using the multifractal detrended fluctuation analysis ...

Research on Efficiency and Multifractality of Gold Market under Major Events

Fractal and Fractional
(1) Background: As a safe-haven asset, gold attracts a large number of investors during major events. Uncertainties caused by global economic and market conditions lead to increased purchases of gold by investors, which in turn affects the efficiency of ...

Master Operators Govern Multifractality in Percolation

, 2000
Using renormalization group methods we study multifractality in percolation at the instance of noisy random resistor networks. We introduce the concept of master operators.

La naturaleza no lineal de los funcionamientos inferenciales: Un estudio empírico con base en el humor gráfico

Avances en Psicología Latinoamericana, 2012
This paper is meant to open the question of whether inferential functioning has a dynamic non lineal system structure. Inferential functioning has been studied from four graphic jokes.
