Une méthodologie et un outil pour le prototypage rapide des entrepôts de données en utilisant le data mining : application à la biodiversité des oise…
2014
International audience; Data Warehouses (DWs) are large repositories of data aimed at supporting the decision-making process by enabling flexible and interactive analyses via OLAP systems. Rapid prototyping of DWs is necessary when OLAP applications are complex. Some work about the integration of Data Mining and OLAP systems has been done to enhance OLAP operators with mined indicators, and/or to define the DW schema. However, to best of our knowledge, prototyping methods for DWs do not support this kind of integration. Then, in this paper we present a new prototyping methodology for DWs, extending [3], where DM methods are used to define the DW schema. We validate our approach on a real da…
Historique de l'utilisation des herbicides en France: premières analyses
2010
A data base on the herbicides used in France since 1961 has been built up from the phytosanitary index annually edited by the Association de Coordination Technique Agricole (ACTA). This data base gives the number of active ingredients, associations and commercial products registered every year and for each crop. We also gathered the modes of action, the way of absorption sites and the species susceptibility. Since 1961, 215 molecules have been registered. The number increased regularly with a maximum of 138 in 2002 and only around 100 remain in 2010. The evolution of the number of modes of action available for weed control in wheat is discussed.
Development of a knowledge graph framework to ease and empower translational approaches in plant research: a use-case on grain legumes
2023
Legumes, and especially pulses, are an important source of protein for food and feed, and are appreciated for their positive impact on the “one health”. However, their unstable yields and their susceptibility to biotic and abiotic stresses highlight the need for varietal improvement in order to increase the cultivated areas and productivity. With the advent of sequencing technologies, a large pool of genetic and -omics resources, heterogeneous at the inter- and intra-species scale, is emerging. Thus, it is important to capitalize on these scattered heterogeneous data to develop translational research to boost breeding projects and crop diversification. To meet this need, we undertook the de…

Les formations à silex dans le Sud de la France : Élaboration en multipartenariat d’une base de données géoréférencées, premiers résultats.
2016
A georeferenced database of the main flint-bearing formations of Southern France is currently being finalised. It offers a toolto all prehistorians that is essential for the development of studies regarding raw material circulation and selection criteria. This database results from the collaborative work of various actors involved in the optimisation of flint source determination. It groups together the results of their surveys — whether these are systematic or targeted — carried out in six regions (Aquitaine, Auvergne, Languedoc-Roussillon, Midi-Pyrénées, Provence-Alpes-Côte d’Azur, Rhône-Alpes). This database also incorporates recent studies on registering the properties of palaeoenvironm…

The Pros and Cons of Beyond Standard Model Interpretations of ANITA Events
2019
The Antarctic Impulsive Transient Antenna (ANITA) experiment has observed two air shower events with energy $\sim 500~{\rm PeV}$ emerging from the Earth with exit angles $\sim 30^\circ$ above the horizon. As was immediately noted by the ANITA Collaboration, these events (in principle) could originate in the atmospheric decay of an upgoing $\tau$-lepton produced through a charged current interaction of a $\nu_\tau$ inside the Earth. However, the relatively steep arrival angles of these perplexing events create tension with the standard model (SM) neutrino-nucleon interaction cross section. Deepening the conundrum, the IceCube neutrino telescope and the Pierre Auger Observatory with substanti…
Pharmacogenomic identification of small molecules for lineage specific manipulation of subventricular zone germinal activity
2017
Strategies for promoting neural regeneration are hindered by the difficulty of manipulating desired neural fates in the brain without complex genetic methods. The subventricular zone (SVZ) is the largest germinal zone of the forebrain and is responsible for the lifelong generation of interneuron subtypes and oligodendrocytes. Here, we have performed a bioinformatics analysis of the transcriptome of dorsal and lateral SVZ in early postnatal mice, including neural stem cells (NSCs) and their immediate progenies, which generate distinct neural lineages. We identified multiple signaling pathways that trigger distinct downstream transcriptional networks to regulate the diversity of neural cells …
