Revisiting the decay of missing ordinal patterns in long-term correlated time series
(Elsevier Science, 2019-11-15)
We revisit the decay of missing ordinal patterns in long-term correlated time series. More precisely, a stretched exponential model is proposed to describe more appropriately how the number of missing ordinal patterns ...
Faceted patterns and anomalous surface roughening driven by long-range temporally correlated noise
(American Physical Society, 2019-06)
We investigate Kardar-Parisi-Zhang (KPZ) surface growth in the presence of power-law temporally correlated noise. By means of extensive numerical simulations of models in the KPZ universality class we find that, as the ...
Mutual information identifies spurious Hurst phenomena in resting state EEG and fMRI data
(American Physical Society, 2018-02)
Long-range memory in time series is often quantified by the Hurst exponent H, a measure of the signal's variance across several time scales. We analyze neurophysiological time series from electroencephalography (EEG) and ...
Temporal correlations imaging fixed targets through turbulence
(Optical Society of America, 2016-06)
We study the temporal correlations from dynamic imaging through turbulence using incoherent light from fixed highcontrast targets. We conduct our experiment in controlled laboratory conditions using several values of the ...
Can oil prices help estimate commodity futures prices? The cases of copper and silver
(ELSEVIER SCI LTD, 2010)
There is an extensive literature on modeling the stochastic process of commodity futures. It has been shown that models with several risk factors are able to adequately fit both the level and the volatility structure of ...
Sobre el uso de distribuciones de ventanas para la transformación de señales estocásticas

Optic tectum morphogenesis: A step-by-step model based on the temporal-spatial organization of the cell proliferation. Significance of deterministic and stochastic components subsumed in the spatial organization
(Wiley-liss, Div John Wiley & Sons Inc, 2012-06)
Background: Cell proliferation plays an important morphogenetic role. This work analyzes the temporal-spatial organization of cell proliferation as an attempt to understand its contribution to the chick optic tectum (OT) ...
Ordinal pattern and statistical complexity analysis of daily stream flow time series
(Springer, 2013-06)
When calculating the Bandt and Pompe ordinal pattern distribution from given time series at depth D, some of the D! patterns might not appear. This could be a pure finite size effect (missing patterns) or due to dynamical ...
