A Semantic Model for Federated Queries Over a Normalized Corpus
We present here a model implemented in OWL which improves information retrieval and data integration of the corpus. The model is populated with entities from CALBC and some simple queries over it are presented.

The CALBC RDF Triple store: retrieval over large literature content
Integration of the scientific literature into a biomedical research infrastructure requires the processing of the literature, identification of the contained named entities (NEs) and concepts, and to represent the content in a standardised way.
The CALBC project partners (PPs) have produced a large-scale annotated biomedical corpus with four different semantic groups through the harmonisation of annotations from automatic text mining solutions (Silver Standard Corpus, SSC). The four semantic groups were chemical entities and drugs (CHED), genes and proteins (PRGE), diseases and disorders (DISO) and species (SPE). The content of the SSC has been fully integrated into RDF Triple Store (4,568,678 triples) and has been aligned with content from the GeneAtlas (182,840 triples), UniProtKb (12,552,239 triples for human) and the lexical resource LexEBI (BioLexicon). RDF Triple Store enables querying the scientific literature and bioinformatics resources at the same time for evidence of genetic causes, such as drug targets and disease involvement
Amuse-bouches, des chansons pour apprendre
Dans le but d’outiller les enseignants et éducateurs de la petite enfance dans le domaine de la musique et du mouvement, nous avons édité, entre 2009 et 2011, quatre albums Amuse-Bouches constitués principalement de chansons et d’activités qui y sont liées. Une enquête auprès des utilisateurs nous a permis de corroborer les échos positifs que nous avons reçus du terrain, mais nous amène aussi à considérer les différents facteurs qui entrent en compte dans la mise en pratique d’un nouvel outil d’enseignement
Checking the reliability of opacity databases
Mathematical inequalities, combined with atomic-physics sum rules, enable one
to derive lower and upper bounds for the Rosseland and/or Planck mean
opacities. The resulting constraints must be satisfied, either for pure
elements or mixtures. The intriguing law of anomalous numbers, also named
Benford's law, is of great interest to detect errors in line-strength
collections required for fine-structure calculations. Testing regularities may
reveal hidden properties, such as the fractal nature of complex atomic spectra.
The aforementioned constraints can also be useful to assess the reliability of
experimental measurements. Finally, we recall that it is important to quantify
the uncertainties due to interpolations in density-temperature opacity (or more
generally atomic-data) tables, and that convergence studies are of course
unavoidable in order to address the issue of completeness in terms of levels,
configurations or superconfigurations, which is a cornerstone of opacity
calculations.Comment: submitted to "Eur. Phys. J. D
X-ray scattering from stepped and kinked surfaces: An approach with the paracrystal model
A general formalism of X-ray scattering from different kinds of surface
morphologies is described. Based on a description of the surface morphology at
the atomic scale through the use of the paracrystal model and discrete
distributions of distances, the scattered intensity by non-periodic surfaces is
calculated over the whole reciprocal space. In one dimension, the scattered
intensity by a vicinal surface, the two-level model, the N-level model, the
faceted surface and the rough surface are addressed. In two dimensions, the
previous results are generalized to the kinked vicinal surface, the two-level
vicinal surface and the step meandering on a vicinal surface. The concept of
crystal truncation rod is generalized considering also the truncation of a
terrace by a step (yielding a terrace truncation rod) and a step by a kink
(yielding a step truncation rod).Comment: 33 pages, 18 figure
Integration of the scientific literature into the Semantic Web: Facts from biomedical data resources
Scientific literature is the primary resource for relevant and innovative information. The integration of the literature with other data resources in the biomedical research community generates overhead that can be avoided through the used of Semantic Web Technology generating openly accessible data. Projects such as SESL and CALBC have producted significant amount of data that that are ready for exploitation.
The tutorial will teach different approaches on how to integrate the scientific literature with the content from biomedical databases, and will discuss the inferences that can be achieved. Furthermore, the tutorial will point to the resources that are ready for use and enable integration of the literature at your discretion. A good understanding of Semantic Web technology, ontologies, OWL and the existing biomedical data resources is advantageous to easily follow the tutorial
