L'élevage larvaire des poissons marins : chaînes alimentaires et aliments composés [PDF]
Bulletin Français de Pisciculture, 1977 L'approvisionnement quotidien en nourriture est, en règle générale, le principal facteur limitant de productions à grande échelle de jeunes poissons marins.La pêche de plancton dans la nature a été, et reste, le moyen d'expérimentation le plus immédiat, et le plus satisfaisant sur le plan qualitatif. Mais la récolte des quantités nécessaires, au moment

Deconvolution of confocal microscopy images using proximal iteration and sparse representations [PDF]
, 2008 We propose a deconvolution algorithm for images blurred and degraded by a Poisson noise. The algorithm uses a fast proximal backward-forward splitting iteration.

Source detection using a 3D sparse representation: application to the Fermi gamma-ray space telescope [PDF]
, 2009 The multiscale variance stabilization Transform (MSVST) has recently been proposed for Poisson data denoising. This procedure, which is nonparametric, is based on thresholding wavelet coefficients. We present in this paper an extension of the MSVST to 3D

A proximal iteration for deconvolving Poisson noisy images using sparse representations [PDF]
, 2008 We propose an image deconvolution algorithm when the data is contaminated by Poisson noise. The image to restore is assumed to be sparsely represented in a dictionary of waveforms such as the wavelet or curvelet transforms.

Etat de santé des poissons. Région marine Manche-Atlantique [PDF]
, 2023 La présente fiche indicateur candidat concerne l’évaluation de l’état de santé des poissons par rapport aux effets des contaminants chimiques, à travers des mesures de biomarqueurs sur des poissons plats. Les données proviennent de campagnes océanographiques organisées dans le cadre du Suivi des Effets bioLogiques Induits par la contamination chimique (

Protocoles pour l'étude histologique de gonades de poissons marins
, 2023 Ce recueil de protocoles a été mis en place dans le cadre du projet MATO (MATurité Objective des poisons par histologie quantitative) et dans le cadre de la thèse de Carine Sauger. Le projet MATO financé par l’IFREMER (Institut Français de Recherche pour l’Exploitation de la Mer) a pour but d’améliorer la détermination de la maturité sexuelle chez ...

The local Gromov-Witten theory of CP^1 and integrable hierarchies
, 2012 In this paper we begin the study of the relationship between the local Gromov-Witten theory of Calabi-Yau rank two bundles over the projective line and the theory of integrable hierarchies. We first of all construct explicitly, in a large number of cases,

Electrocardiographic Abnormalities and Treatment with Benznidazole among Children with Chronic Infection by Trypanosoma cruzi: A Retrospective Cohort Study [PDF]
, 2016 Background: Chronic infection by Trypanosoma cruzi could cause heart conduction disturbances. We sought to analyze electrocardiographic abnormalities among children with chronic T. cruzi infection with and without trypanocidal treatment with benznidazole.

Deconvolution under Poisson noise using exact data fidelity and synthesis or analysis sparsity priors [PDF]
, 2011 In this paper, we propose a Bayesian MAP estimator for solving the deconvolution problems when the observations are corrupted by Poisson noise. Towards this goal, a proper data fidelity term (log-likelihood) is introduced to reflect the Poisson ...

The Three-Point Correlation Function of Luminous Red Galaxies in the Sloan Digital Sky Survey [PDF]
, 2007 We present measurements of the redshift-space three-point correlation function of 50,967 Luminous Red Galaxies (LRGs) from Data Release 3 (DR3) of the Sloan Digital Sky Survey (SDSS).
