Structure functions and flatness of streamwise velocity in a turbulent channel flow
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas B. Garnier
In this article, we present a multiscale characterization of the streamwise velocity of a turbulent channel flow. We study the 2nd and 4th order structure functions and the flatnes…
Relationship between unpredictability and intermittency in shell models of turbulence and experiments
Ewen Frogé, Carlos Granero-Belinchon, Stéphane G. Roux +2
We study the predictability of turbulent velocity signals using probabilistic analog-forecasting. Here, predictability is defined by the accuracy of forecasts and the associated un…
Analog-Based Forecasting of Turbulent Velocity: Relationship between Unpredictability and Intermittency
Ewen Frogé, Carlos Granero-Belinchon, Stéphane G. Roux +2
This study evaluates the performance of analog-based methodologies to predict, in a statistical way, the longitudinal velocity in a turbulent flow. The data used comes from hot wir…
Multiscale and Anisotropic Characterization of Images Based on Complexity: an Application to Turbulence
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas B. Garnier
This article presents a multiscale, non-linear and directional statistical characterization of images based on the estimation of the skewness, flatness, entropy and distance from G…
Quantifying Non-Stationarity with Information Theory
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas B. Garnier
We introduce an index based on information theory to quantify the stationarity of a stochastic process.The index compares on the one hand the information contained in the increment…
Distance to healthy cardiovascular dynamics from fetal heart rate scale-dependent features in pregnant sheep model of human labor predicts cardiovascular decompensation
Stéphane G. Roux, Nicolas B. Garnier, Patrice Abry +2
The overarching goal of the present work is to contribute to the understanding of the relations between fetal heart rate (FHR) temporal dynamics and the well-being of the fetus, no…
Frequency gradients in heterogeneous oscillatory media can spatially localize self-organized wave sources that coordinate system-wide activity
Ria Ghosh, Pavithraa Seenivasan, Shakti N. Menon +4
Rhythmogenesis, which is critical for many biological functions, involves a transition to coherent activity through cell-cell communication. In the absence of centralized coordinat…
Information theory for non-stationary processes with stationary increments
Carlos Granero-Belinchon, Stéphane G. Roux, Nicolas Garnier
We describe how to analyze the wide class of non stationary processes with stationary centered increments using Shannon information theory. To do so, we use a practical viewpoint a…
Probing high order dependencies with information theory
C Granero-Belinchón, S. Roux, P. Abry +1
Information theoretic measures (entropies, entropy rates, mutual information) are nowadays commonly used in statistical signal processing for real-world data analysis. The present…
Information Theory to probe Intrapartum Fetal Heart Rate Dynamics
Carlos Granero-Belinchon, Stéphane Roux, Patrice Abry +3
Intrapartum fetal heart rate (FHR) monitoring constitutes a reference tool in clinical practice to assess the baby health status and to detect fetal acidosis. It is usually analyze…
A Kullback-Leibler divergence measure of intermittency: application to turbulence
Carlos Granero-Belinchon, Stephane G. Roux, Nicolas B. Garnier
For generic systems exhibiting power law behaviors, and hence multiscale dependencies, we propose a new, and yet simple, tool to analyze multifractality and intermittency, after no…
Scaling of Information in Turbulence
Carlos Granero-Belinchon, Stephane G. Roux, Nicolas B. Garnier
We propose a new perspective on Turbulence using Information Theory. We compute the entropy rate of a turbulent velocity signal and we particularly focus on its dependence on the s…
The role of cellular coupling in the spontaneous generation of electrical activity in uterine tissue
Jinshan Xu, Shakti N. Menon, Rajeev Singh +3
The spontaneous emergence of contraction-inducing electrical activity in the uterus at the beginning of labor remains poorly understood, partly due to the seemingly contradictory o…
