Israël Palestine sous les cartes
No full textColloque international antiAtlas des FrontièresNouveau Conservatoire Darius Milhaud, Aix-en-ProvenceDu 30 septembre au 2 octobre 2013« Israël Palestine sous les cartes » est un projet de visualisation dynamique des chaînes relationnelles développées par un anthropologue au cours de ses enquêtes de terrain dans l’espace israélo-palestinien (2005-2010). Ce travail exploratoire implique un anthropologue (Cédric Parizot), un sociologue (Antoine Vion) et un spécialiste de visualisation de données complexes (Wouter Van den Broeck). Le premier objectif est d’analyser sous un autre angle le niveau d’imbrication entre espaces israéliens et palestiniens. Le second est de confronter les trois chercheurs à des pratiques, des méthodologies et des données inhabituelles émanant d’autres disciplines. D’une part, en ayant recourt à un niveau beaucoup plus élevé d’abstraction, l’anthropologue opère un repositionnement radical par rapport à ses données de terrain. En dépit de la perte temporaire de la précision de l’observation anthropologique, cette visualisation dynamique lui offrira une compréhension plus globale du monde social dans lequel il a évolué. D’autre part, cette expérience permettra au sociologue et à l’anthropologue de mieux apprécier les conditions de production de leur connaissance, non seulement en tenant compte du fait que ces données sont situées dans le temps, dans l’espace et dans des interactions spécifiques, mais aussi et surtout en soulignant que l’anthropologue et le sociologue font partie intégrante du réseau-frontière qu’ils tentent de déchiffrer. En d’autres termes, ce projet implique l’anthropologue et sociologue à la fois en tant que chercheurs et en tant qu’objets de recherche. Enfin, en traitant un autre type de réseau complexe (impliquant moins d’individus, mais des couches plus complexes d’interactions), Wouter van den Broeck a l’intention d’expérimenter une nouvelle sémiologie de la cartographie de réseau applicable à l’étude des réseaux issus de la recherche qualitative
Entropy production as correlation between system and reservoir
No full textpeer reviewedWe derive an exact (classical and quantum) expression for the
entropy production of a finite system placed in contact with one or several
finite reservoirs, each of which is initially described by a canonical equilibrium
distribution. Although the total entropy of system plus reservoirs is conserved,
we show that system entropy production is always positive and is a direct
measure of system–reservoir correlations and/or entanglements. Using an
exactly solvable quantum model, we illustrate our novel interpretation of the
Second Law in a microscopically reversible finite-size setting, with strong
coupling between the system and the reservoirs. With this model, we also
explicitly show the approach of our exact formulation to the standard description
of irreversibility in the limit of a large reservoir
Three new species in the lichen genus Piccolia (Biatorellaceae, lichenized Ascomycota) from the Palaeotropics
No full textBackground – As part of taxonomic revisions of tropical African lichens, two species of Piccolia are described as new to science while a third unknown one collected in the Solomon archipelago was kindly send to us by the second author. Material and Methods – Morphology was studied using a stereo and light microscope. Chemistry was studied with spot tests and TLC. Key results – P. congolensis Van den Broeck, Aptroot & Ertz sp. nov. was collected twice in the Democratic Republic of the Congo and is characterized notably by a thallus with KC+ orange soralia. The material recorded recently from Reunion Island as P. elmeri (Vain.) Hafellner was shown to represent a different species characterized by a completely dark brown excipulum and is described here as P. kalbii Van den Broeck & Ertz sp. nov. P. nivea Van den Broeck, Aptroot & Ertz sp. nov. is only known from the type location on the Solomon archipelago and is characterized by grey pruinose ascomata and a thallus resembling a leprose crust. A worldwide key to the genus is provided
The making of sixty-nine days of close encounters at the science gallery
No full textThe SocioPatterns sensing platform uses wearable electronic badges to sense close-range proximity among individuals. It was used in an experiential exhibit that simulated a virtual epidemic among the visitors of the INFECTIOUS: STAY AWAY exhibition in the Science Gallery in Dublin, Ireland. The collected data was used to generate a highresolution visualization that illustrates the variation in contact activity over the course of the exhibition. © 2012 ISAST
The utopian challenge to global capitalism by Walter van den Broeck in <i>Terug naar Walden</i>
No full textThe socialist sympathies that inform the writing of Flemish author Walter van den Broeck align him with a well-established tradition of socially engaged writing in Flanders. In his novel Terug naar Walden (Back to Walden), published in 2009, he revisits the Walden project of the Dutch reformer and writer Frederik van Eeden (1860−1932). Van den Broeck suggests that a reconsideration of the socialist ideals that inspired Van Eeden to establish settlements in the Netherlands and the United States is warranted in the light of the economic crisis triggered by unchecked capitalist practices in 2008. In Terug naar Walden Ruler Marsh, the richest man in the world, unleashes a global financial crisis as a form of retaliation against the capitalist system that ruined his parents. Marsh returns to the Kempen in Flanders where his family originated. In a Heideggerean affirmation of the local as exemplified by the country road, Van den Broeck articulates his vision of the common, that theorists Michael Hardt and Antonio Negri in their Empire trilogy have attempted to salvage from communist thinking, with a utopian notion that a stronger connection with the land and the people within one’s immediate environment may provide a useful premise for the development of viable alternatives to capitalism

Quantification of Celiac Disease Gluten Epitopes
No full textScientists have published a novel method in the Journal of Chromatography A to detect multiple celiac disease-epitopes in wheat extracts simultaneously using liquid chromatography–multiple reaction monitoring mass spectrometry (LC–MRM–MS).1 Celiac disease is caused by an immune response in the small intestine from eating gluten proteins. An enzyme-linked immunosorbent assay (ELISA) is the standard testing method for food, but this can be inaccurate and does not differentiate between gluten proteins. Lead author Hetty van den Broeck told The Column: “This newly developed method based on mass spectrometry quantifies specifically celiac disease stimulating epitopes. This is not possible by ELISA, which detects gluten proteins in general by using a monoclonal antibody. Mass spectrometry allows specific detection and quantification of multiple CD-epitopes at the same time. This is necessary because of the complex genome of bread wheat and the many different CD-epitopes to which CD-patients can respond differentially.” In the current study, gluten extracts were prepared from wheat and extracted prior to LC–MRM–MS analysis. The authors developed the method to detect peptides known to induce the strongest immune response, as well as peptides with amino acid substitutions that make them harmless. The method was able to quantify different peptide isoforms, showing that a modern wheat variety, Toronto, contained the highest level of CD immunogenic peptides. The team are continuing their work to test and select reduced immunogenic wheat varieties, van den Broeck told The Column. She said: “We are also working on the development of screening body fluids from CD-patients for the presence of these epitopes or other specific peptide biomarkers for CD.”— B.
The live social semantics application: A platform for integrating face-to-face presence with on-line social networking
No full textWe describe a novel application that integrates real-world data on the face-to-face proximity of individuals with their identities and contacts in on-line social networks. This application was successfully deployed at two conference gatherings, ESWC09 and HT2009, and actively used by hundreds of people. Personal profiles of the participants were automatically generated using several Web 2.0 systems and semantic data sources, and integrated in real-time with face-to-face proximity relations detected using RFID-enabled badges. The integration of these heterogeneous data sources enables various services that enhance the experience of conference attendees, allowing them to explore their social neighbourhood and to connect with other participants. This paper describes the architecture of the application, the services we provided, and the results we achieved in these deployments

Live Social Semantics
No full textSocial interactions are one of the key factors to the success of conferences and similar community gatherings. This paper describes a novel application that integrates data from the semantic web, online social networks, and a real-world contact sensing platform. This application was successfully deployed at ESWC09, and actively used by 139 people. Personal profiles of the participants were automatically generated using several Web~2.0 systems and semantic academic data sources, and integrated in real-time with face-to-face contact networks derived from wearable sensors. Integration of all these heterogeneous data layers made it possible to offer various services to conference attendees to enhance their social experience such as visualisation of contact data, and a site to explore and connect with other participants. This paper describes the architecture of the application, the services we provided, and the results we achieved in this deployment
