“Socio-Semantic Web”(S2W) applications, such as “Knowledge-Based MarketPlaces” (KBMs), lead to co-construct symbolic organizational artifacts including “maps” or others semantic instruments, bringing a visibility and a reflexivity of the knowledge and of the action in communities. In presenting and comparing examples of KBMs, we note that the creation and the whole lifecycle of such S2W applica...

In this work, Pt, Fe and Co nanoparticles were prepared by chemical reduction of the metal salts in chitosan as the support. NaBH4 was used as the reducing agent Pt-Fe, Pt-Co and Pt-Fe-Co-chitosan nanocomposites were synthesized and characterized by UV–Vis spectra and Transmission electron microscopy images. GC/Pt-chitosan, GC/Pt-Co-chitosan, GC/Pt-Fe-chitosan and GC/Pt-Co-Fe-chitosan electrode...

We consider the simplification of logic programs under the stablemodel semantics, with respect to the notions of strong and uniform equivalence between logic programs, respectively. Both notions have recently been considered for nonmonotonic logic programs (the latter dates back to the 1980s, though) and provide semantic foundations for optimizing programs with input. Extending previous work, w...

cd27 is a biomarker associated with both t-cells and b-cells activation .plasma soluble cd27 (scd27) was identified as  a marker of disease outcome in human immunodeficiency virus (hiv) infection .testing of plasma scd27 represents a good tool to monitor the change of immune activation during hiv infection.we sought to analyses role of hepatitis c virus (hcv) and also gb virus type c (gbv-c) co...

Our everyday actions are often performed in the context of a social interaction. We previously showed that, in adults, selecting an action on the basis of either social or symbolic cues was associated with activations in the fronto-parietal cognitive control network, whereas the presence and use of social versus symbolic cues was in addition associated with activations in the temporal and media...

Recent progress in functional neuroimaging has prompted studies of brain activation during various cognitive tasks. Coordinate-based meta-analysis has been utilized to discover the brain regions that are consistently activated across experiments. However, within-experiment co-activation relationships, which can reflect the underlying functional relationships between different brain regions, hav...
