A model of stimulus-specific neural assemblies in the insect antennal lobe Inra
Martinez, D.; Montejo, N..
A fundamental question in computational neuroscience is to understand how interactions between neurons underlie sensory coding and information storage. In the first relay of the insect olfactory system, odorant stimuli trigger synchronized activities in neuron populations. Synchronized assemblies may arise as a consequence of inhibitory coupling, because they are disrupted when inhibition is pharmacologically blocked. Using computational modelling, we studied the role of inhibitory, noisy interactions in producing stimulus-specific synchrony. So far, experimental data and modelling studies indicate that fast inhibition induces neural synchrony, but it remains unclear how desynchronization occurs. From theoretical analysis and computer simulations, we found...

A model of the relationship between light and primary production in an atoll lagoon IRD
Charpy, Loïc; Charpy Roubaud, Claude.
The Tikehau atoll (Tuamotu Archipelago, French Polynesia) is located at 14°S 148°W. Phytoplankton and sand microalgae are the most important primary producers of the lagoon. They were studied for 4 years. The relationship between light energy and lagoonal primary production was measured by using the 14C method for phytoplankton and O2 method for phytobenthos. Incubations, carried out #in situ$, were made at different depths and light exposition times. Irradiance was hight and 17% of the light energy measured at the surface reached 25 m (lagoon average depth). Maxima of phytoplankton and phytobenthos productions occured at low depths; there was therefore no photoinhibition of photosynthesis. Correlations between light energy and primary production were...

A model study of potential sampling errors due to data scatter around expendable bathythermograph transects in the Tropical Pacific IRD
McPhaden, M.J.; Busalacchi, A.J.; Picaut, Joël; Raymond, G..
We describe a series of sampling sensitivy experiments to examine potential errors due to data scatter around expendable bathythermograph (XBT) transects in the tropical Pacific. We use a linear, multiple vertical mode model forced with three differrent monthly mean wind stress sets for the period 1979-1983. The model is sampled along approximately straight lines of grid points corresponding to the mean positions of XBT tracks in the eastern, central, and western Pacific and then sampled again at the dates and location of actual XBT casts for 1979-1983. Model dynamic heights are calculated with a resolution of 1° of latitude and 1 month, then processed to a monthly mean seasonal cycle and anomalies associated with the 1982-1983 El Nino. When results are...

A new two-scale model describing drying dynamics and coupled heat and mass transfer in a porous medium: application to the combined vacuum drying and radiative heating of wood Inra
Turner, I.; Perré, P..
In this work a two-scale modelling approach is used to investigate the vacuum drying of a board placed in an experimental vacuum chamber, whereby two infrared emitters with reflectors are used to supply heat to the product. The kiln (large) scale model allows the evolution of the masses of vapour, air and water in the chamber, together with the temperatures of the vacuum chamber and the IR emitters to be monitored throughout the drying process. Such a model enables condensation on the kiln walls to be accounted for in the evolution of the relative humidity within the chamber. The comprehensive two-dimensional drying model, known as Transpore, is used to determine the heat and mass transfer at the (macro) scale of the board. The knowledge of the vacuum...

Analyse et diagnostic des fautes dans un environnement multi-domaines : une approche hiérarchique et distribuée IRD
Mahamat, G.; Das, A..
Dans cet article, nous décrivons une approche hiérarchique et distribuée d'analyse et de diagnostic des fautes dans un environnement multi-domaines. L'approche est basée sur les modèles normalisés de gestion de réseaux et les idées développées par l'intelligence artificielle distribuée selon lesquelles un ensemble d'agents intelligents coopèrent pour la résolution d'un problème. L'article donne dans un premier temps une description sommaire des modèles de base utilisés. Il présente ensuite l'approche d'analyse et de diagnostic des fautes. La conclusion du document présente nos futurs travaux. (Résumé d'auteur)

Analysis of CATMA transcriptome data identifies hundreds of novel functional genes and improves gene models in the Arabidopsis genome Inra
Aubourg, S.; Martin-Magniette, M.L.; Brunaud, V.; Taconnat, L.; Bitton, F.; Balzergue, S.; Jullien, P.E.; Ingouff, M.; Thareau, V.; Schiex, T.; Lecharny, A.; Renou, J.P..
Background: Since the finishing of the sequencing of the Arabidopsis thaliana genome, the Arabidopsis community and the annotator centers have been working on the improvement of gene annotation at the structural and functional levels. In this context, we have used the large CATMA resource on the Arabidopsis transcriptome to search for genes missed by different annotation processes. Probes on the CATMA microarrays are specific gene sequence tags (GSTs) based on the CDS models predicted by the Eugene software. Among the 24 576 CATMA v2 GSTs, 677 are in regions considered as intergenic by the TAIR annotation. We analyzed the cognate transcriptome data in the CATMA resource and carried out data-mining to characterize novel genes and improve gene models....
