Analysis of Cardiac Vibration Signals Acquired From a Novel Implant Placed on the Gastric Fundus

Autor: Henry Areiza-Laverde, Cindy Dopierala, Lotfi Senhadji, Francois Boucher, Pierre Y. Gumery, Alfredo Hernández

Publikováno v: Frontiers in Physiology, Vol 12 (2021)

The analysis of cardiac vibration signals has been shown as an interesting tool for the follow-up of chronic pathologies involving the cardiovascular system, such as heart failure (HF). However, methods to obtain high-quality, real-world and longitud

Time localization of transients with wavelet maxima lines

Autor: P.-Y. Gumery, Sophie Achard, Sylvain Meignen

Publikováno v: IEEE Transactions on Signal Processing. 53:2251-2258

In this study, we present a new estimator of transients built from the extrema of a signal decomposition first introduced by Berkner. We study the performance of the new estimator of transients both for a variation of amplitude and a variation of fre

International audience; To what extent is Empirical Mode Decomposition (EMD) able to differentiate the embedded components of a cardio-respiratory (CR) signal? We intend to answer this question by providing a tool which compares the performances of t

Reconstruction of Finite Signal Derivatives from Multiscale Extrema Representations: Application to Transient and Signal Approximation

Autor: Sylvain Meignen, P.-Y. Gumery

Publikováno v: IEEE Transactions on Signal Processing
IEEE Transactions on Signal Processing, Institute of Electrical and Electronics Engineers, 2007, 55 (4), pp.1554-1559. ⟨10.1109/TSP.2006.887570⟩

International audience; In this correspondence, we propose a novel approach to the reconstruction of finite signal derivatives from the extrema of a multiscale representation, first introduced by Berkner. We show that this reconstruction procedure na

Single cell volume measurement using a computer controlled patch-clamp electrode displacement

Autor: M. Asfour, P.-Y. Gumery, A. Queyroy, J. Verdetti, E. Novakov

Publikováno v: Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

Using a hydraulic micromanipulator, the authors have developed a new instrument to pilot precisely the displacement of a patch-electrode via a PC. The aim of this instrument is to measure the changes of the height of a single cell in culture using th

Modelling biological gel contraction by cells: mechanocellular formulation and cell traction force quantification

Autor: I, Ferrenq, L, Tranqui, B, Vailhé, P Y, Gumery, P, Tracqui

Publikováno v: Acta biotheoretica. 45(3-4)

Traction forces developed by most cell types play a significant role in the spatial organisation of biological tissues. However, due to the complexity of cell-extracellular matrix interactions, these forces are quantitatively difficult to estimate wi
