Extending SPARQL with Temporal Logic
2009
The data integration and sharing activities carried on in the framework of the Semantic Web lead to large knowledge bases that must be queried, analyzed, and exploited efficiently. Many of the knowledge representation languages of the Semantic Web, starting with RDF, are based on directed, labeled graphs, which can be also manipulated using graph algorithms and tools coming from other domains. In this paper, we propose an analysis approach of RDF graphs by reusing the verification technology developed for concurrent systems. To this purpose, we define a translation from the SPARQL query language into XTL, a general-purpose graph manipulation language implemented in the CADP verification too…
Short term adaptive response of symbiotic N2 fixation in pea to root pruning of half the root system, linked to the availability of carbon assimilates
2014
Symbiotic N fixation of legumes is very sensitive to environmental stresses, like pea pests damaging nodulated roots. However, the impact on their N uptake capacity and plant growth has not been studied so far.We analyzed the adaptive response symbiotic N2 fixation and plant growth of pea wild type Frisson and hypernodulating mutants P64, P118 and P121 mutated respectively on genes SYM28, SYM29 and NOD3 to root pruning of half the root system at the end of the vegetative stage. The adaptive responses of pea: cv. Frisson and 3 of its hypernodulating mutants were compared under varying carbon supplies from photosynthesis.At 380 ppm, mutant P118 showed the lowest decrease of the specific activ…
AN ONTOLOGY-BASED RECOMMENDER SYSTEM USING HIERARCHICAL MULTICLASSIFICATION FOR ECONOMICAL E-NEWS
2014
International audience; This paper focuses on a recommender system of economic news articles. Its objectives are threefold: (i) automatically multi-classify new economic articles, (ii) recommend articles by comparing profiles of users and multi-classification of articles, and (iii) managing the vocabulary of the economic news domain to improve the system based on seamlessly intervention of documentalists. In this paper we focus on the automatic multi-classification of the articles, managed by inference process of ontologies, and the enrichment of the documentalist-oriented ontology which provides the necessary capabilities to the DL reasoner for automatic multi-classification.
A Note on Radio Antipodal Colouring of Paths
2005
International audience; The radio antipodal number of a graph G is the smallest integer c such that there exists an assignment f : V (G) -> {1, 2, . . . , c} satisfying |f(u) − f(v)| >= D − d(u, v) for every two distinct vertices u and v of G, where D is the diameter of G. In this note we determine the exact value of the antipodal number of the path, thus answering the conjecture given in [G. Chartrand, D. Erwin, and P. Zhang. Radio antipodal colorings of graphs, Math. Bohem. 127(1):57-69, 2002]. We also show the connections between this colouring and radio labelings.

Ex Ante evaluation of gene flow in oilseed rape with cropping system models
2013
Chapitre 4; Oilseed rape (OSR) genes can escape fields in space via pollen and seeds, and in time via volunteers resulting from seeds lost before or during oilseed rape harvest. When varieties co-exist, e.g. genetically-modified (GM) and non-GM varieties, this spatio-temporal gene flow can lead to the adventitious presence of GM seeds in non-GM harvests and thus cause financial losses for farmers and cooperatives. Gene flow depends on crop locations, succession, and management, as well as the location and management of semi-natural areas such as roadverges. The objective of this investigation was to present a simulation methodology using the spatially-explicit cropping system model GENESYS …

Changes in the pea seed proteome in response to drought combined with sulfur deficiency
2017
EABAPGEAPSI DOCT INRA; Pea (Pisum sativum L.) produces seeds rich in proteins, but seed yield and quality remain unstable across years due to abiotic stresses occurring during the reproductive period. Drought and sulfur deficiency are two abiotic stresses that interact in the current context of climate change and lowinput practices, and recent studies suggest a role of sulfate transport and metabolism in the plant response to drought (Ernst et al., 2010; Chan et al., 2013; Gallardo et al., 2014; Ahmad et al., 2016). In this study, we investigated the impact of sulfur deficiency combined with drought on the pea seed proteome. Pea plants were subjected to sulfur-deficiency two weeks after sow…

Gros plan sur ChemoSens, R&D et expertise en analyses physico-chimique et sensorielle. Une plate-forme du Centre des Sciences du Goût et de l'Aliment…
2016
ChemoSens est une plate-forme de recherche publique du Centre des Sciences du Goût et de l'Alimentation (CSGA, unité mixte de recherche CNRS - INRA - Université Bourgogne Franche-Comté). Son originalité repose sur l'utilisation combinée de la chimie et de l'analyse sensorielle pour développer de nouvelles approches de caractérisation des aliments et du comportement alimentaire.
