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.

Levy flights and multifractality in quantum critical diffusion and in classical random walks on fractals

, 2012
We employed the method of virial expansion in order to compute the retarded density correlation function (generalized diffusion propagator) in the critical random matrix ensemble in the limit of strong multifractality. We found that the long-range nature

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 ...

Perturbation approach to multifractal dimensions for certain critical random matrix ensembles

, 2011
Fractal dimensions of eigenfunctions for various critical random matrix ensembles are investigated in perturbation series in the regimes of strong and weak multifractality.

High values of disorder-generated multifractals and logarithmically correlated processes

, 2014
In the introductory section of the article we give a brief account of recent insights into statistics of high and extreme values of disorder-generated multifractals following a recent work by the first author with P. Le Doussal and A.

Quantifying origin and character of long-range correlations in narrative texts

, 2015
In natural language using short sentences is considered efficient for communication. However, a text composed exclusively of such sentences looks technical and reads boring.

Multifractality of climate networks [PDF]

Nonlinear Processes in Geophysics
Geophysical fields are extremely variable over a wide range of space–time scales. More specifically, they are intermittent in the sense that the strongest fluctuations are increasingly concentrated in sparser and sparser fractions of the space–time ...

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.
