This paper deals with the estimation of transfer entropy based on the k-nearest neighbors (k-NN) method. To this end, we first investigate the estimation of Shannon entropy involving a rectangular neighboring region, as suggested in already existing

International audience; Nowadays, Granger causality techniques are frequently applied to investigate complex dynamical systems such as brain networks. Indeed, various derivations have been proposed from the initially basic definition of the Granger c

International audience; Selective internal radiation therapy (SIRT) using Yttrium-90 loaded glass microspheres injected in the hepatic artery is an emerging, minimally invasive therapy of liver cancer. A personalized intervention can lead to high con

Accordion-like collagen fibrils suggested by P-SHG image modeling : implication in liver fibrosis

Autor: François Tiaho, Emmanuel Schaub, D. Rouède, Frédéric Ezan, Jean-Jacques Bellanger

Second-order non-linear optical anisotropy parameter ρ = χ33 / χ31 is calculated for collagen-richt issues considering both a single dominant molecular hyperpolarizability tensor element β333 = β at single helix level and a priori known submicro

Publikováno v: Network: Computation in Neural Systems. 25:139-167

In this paper, a model-based approach is presented to quantify the effective synchrony between hippocampal areas from depth-EEG signals. This approach is based on the parameter identification procedure of a realistic Multi-Source/Multi-Channel (MSMC)
