Reappraisal of ‘chronospecies' and the use of Arvicola (Rodentia, Mammalia) for biochronology.
2008
13 pages; International audience; The water vole, genus Arvicola, is characterised by a broad geographic distribution throughout Europe and is widespread during the late Middle and Upper Pleistocene. This genus is used as a major biostratigraphic tool within the Quaternary. Specific determinations using the Schmelzband-Differenzierung-Quotient or SDQ have identified many chronospecies within the fossil species Arvicola cantiana (Hinton, 1910). As SDQ calculation remains limited, this study reappraises the Arvicola genus in terms of morphodiversity and morphospace using outline analysis which takes into account the tooth as a whole. Outline analysis suggests that one single species of Arvico…
Reactome diagram viewer: data structures and strategies to boost performance
2017
Abstract Motivation Reactome is a free, open-source, open-data, curated and peer-reviewed knowledgebase of biomolecular pathways. For web-based pathway visualization, Reactome uses a custom pathway diagram viewer that has been evolved over the past years. Here, we present comprehensive enhancements in usability and performance based on extensive usability testing sessions and technology developments, aiming to optimize the viewer towards the needs of the community. Results The pathway diagram viewer version 3 achieves consistently better performance, loading and rendering of 97% of the diagrams in Reactome in less than 1 s. Combining the multi-layer html5 canvas strategy with a space partit…
Lièvre et lapin à Regourdou (Montignac-sur-Vézère, Dordogne, France) : études paléontologique et taphonomique de deux accumulations osseuses d’origin…
2015
Since the end of the nineteenth century, a great deal of work studyingsubsistence patterns of prehistoric societies in Western Europe has been done. During the Middle Paleolithic, humanswere interested in small game, particularly the Leporidae, taxa that were abundant in their territories. However,distinguishing the exact nature of their origin in an archaeological site is not an easy task, given that numerous agentscould be responsible for their accumulation (i.e., natural mortality, acquisition by humans and/or other terrestrialcarnivores, or even nocturnal or diurnal raptors). In this contribution, we put forth a new taphonomic and paleontologicalstudy of the leporids of Regourdou, a Mou…
Semantically enriched informed environment for multi-agent simulation : application to simulation in 3D virtual environment
2014
This thesis focuses on multi-agent simulation applied to the simulation of individuals in virtual 3D buildings. To do this, our work suggests to capitalize on the experience gained in the field of semantic web ontologies and inference engines to facilitate the design and development of intelligent behavior for agents operating in virtual worlds. The goal is to provide to agents a generic approach to managing their representation of the world and reason about this representation. For this, the central problem is based on the definition of a decidable ontology modeling all of the knowledge contained in the virtual 3D environment to enrich semantically the environment of a multi-agent simulati…
L'animismo rivisitato e i dibattiti sulle ontologie indigene
2014
Nell'articolo viene analizzata la recente interpretazione della nozione di animismo in antropologia legandola allo sviluppo del dibattito teorico sulle cosiddette 'ontologie indigene' e sui concetti di persona. Da questo punto di vista l'opera di Hallowell ha ispirato molti dei filoni di riflessione contemporanea su questi temi. Tra questi filoni, si possono annoverare: l'antropologia cognitiva di Boyer, l'antropologia fenomenologica di Ingold e Bird-David, la teoria degli schemi della pratica di Descola, la teoria del "prospettivismo amerindiano" di Viveiros de Castro. Dopo avere esaminato i caratteri e i limiti di ognuno di questi filoni, l'articolo si sofferma sulle posizioni più recenti…
Pourquoi la génétique humaine a-t-elle besoin des sciences humaines et sociales ?
2019
L’introduction récente du séquençage haut débit du génome détermine une situation complexe marquée du sceau de l’accélération ; elle pose des problèmes éprouvés par les patients, les médecins ou les chercheurs à partir d’expériences de pratique clinique ou de recherche. Ces pratiques situées suscitent un besoin de réflexivité souvent difficile à assumer dans l’urgence de l’action et la segmentation encore forte des métiers. La Fédération Hospitalo-Universitaire (FHU) TRANSLAD Bourgogne Franche Comté constitue une structure pluridisciplinaire et plurielle pour encadrer l’arrivée du séquençage haut débit dans le soin. Ne préjugeant pas de ses objets, fonctions ou champs, elle se situe d’abord…
Semantic technologies for industry: From knowledge modeling and integration to intelligent applications
2013
Artificial Intelligence technologies are growingly used within several software systems ranging from Web services to mobile applications. It is by no doubt true that the more AI algorithms and methods are used the more they tend to depart from a pure "AI" spirit and end to refer to the sphere of standard software. In a sense, AI seems strongly connected with ideas, methods and tools that are not (yet) used by the general public. On the contrary, a more realistic view of it would be a rich and pervading set of successful paradigms and approaches. Industry is currently perceiving semantic technologies as a key contribution of AI to innovation. In this paper a survey of current industrial expe…
Domain-Specific OWL Ontology Visualization with OWLGrEd
2015
The OWLGrEd ontology editor allows graphical visualization and authoring of OWL 2.0 ontologies using a compact yet intuitive presentation that combines UML class diagram notation with textual Manchester syntax for expressions. We present an extension mechanism for OWLGrEd that allows adding custom information areas, rules and visual effects to the ontology presentation thus enabling domain specific OWL ontology visualizations. The usage of OWLGrEd and its extensions is demonstrated on ontology engineering examples involving custom annotation visualizations, advanced UML class dia-gram constructs and integrity constraints in semantic database schema design.
Dalle geografie terracquee alla Wet Perspective: scie e onde del Mediterraneo Nero
2023
Beginning in the modern age, with the progressive conquest and discovery of the 'Outside', the sea became the leading element in the processes that have marked living in the sphere from then on (Sloterdijk, 2008). Although subject to mutations in time and space, the assumed terracqueous perspective moves away from the exclusivity of terracentrism towards a recognition of the centrality of the space of the sea. A space, on the one hand, that has become central to the production and reproduction of capital through accumulation and exploitation; on the other hand, a social, cultural, political space from which emerge the possibilities of breaking its structures of domination, power, hierarchis…
Sub-Symbolic Mapping of Cyc Microtheories in Data-Driven 'Conceptual' Spaces
2007
The presented work aims to combine statistical and cognitive-oriented approaches with symbolic ones so that a conceptual similarity relationship layer can be added to a Cyc KB microtheory. Given a specific microtheory, a LSA-inspired conceptual space is inferred from a corpus of texts created using both ad hoc extracted pages from the Wikipedia repository and the built-in comments about the concepts of the specific Cyc microtheory. Each concept is projected in the conceptual space and the desired layer of sub-symbolic relationships between concepts is created. This procedure can help a user in finding the concepts that are "sub-symbolically conceptually related" to a new concept that he wan…
