À partir de 2010, l'œuvre du cinéaste expérimental autrichien Martin Arnold a connu une mutation profonde. Alors que ses œuvres précédentes s'employaient à détourner des films de fiction hollywoodiens, le travail contemporain d'Arnold vise, quant à lui, à retravailler des fragments de dessins animés issus de la production Disney. La présente communication se propose d'examiner ce corpus contemporain et d'en dégager les enjeux. Une attention toute particulière est réservée à "Shadow Cuts" (2010), film à l'occasion duquel Arnold renoue avec ses premières amours (le scratching visuel et sonore). [less ▲]

Small conductance calcium-activated potassium (SK, KCa2) channels represent interesting and challenging targets in medicinal chemistry. So far, the reference ligand is apamin, a peptide used in most published studies including the [125I] analog for binding studies. Nonpeptidic ligands with high affinity have been developed for several years. Currently, different questions remain to be solved. No selective and brain-penetrating agent is available. In addition, replacing [125I]apamin in binding experiments would be also interesting. We have developed different series of compounds initially derived from laudanosine (1). The quaternized derivative, N-methyl-laudanosine (NML), was found to be a weak SK blocker but highly reversible in electrophysiological experiments (2). Then, bis-charged derivatives were synthesized. Potentially brain-penetrating AG525 stereoisomers were obtained and tested for their affinity for SK channels (3). The affinity of one enantiomer, AG525E1, was found to be close to that of dequalinium (Ki ~ 200 nM) while the two other stereoisomers had a lower affinity. Following this study, quaternization of AG525 stereoisomers was carried out and the affinity of these compounds for SK channel subtypes was determined in comparison with that of parent compounds. We observed a significant increase of affinity for SK2 and SK3 channels for the bis-charged N-methyl derivatives as compared to the basic AG525 stereoisomers to. The ratio of selectivity was increased a little in the case of bis-charged N-methyl derivatives. In addition, the influence of stereochemistry was quite different between both groups. For basic AG525 stereoisomers, the S,S-enantiomer (AG525E1) was the most potent while, within bis-charged N-methyl analogues, both enantiomers had higher affinity. Further in silico approaches should permit to explain these results. References: (1) Graulich et al., Bioorg. Med. Chem. 2005, 13, 1201 (2) Scuvée-Moreau et al., J. Pharmacol. Exp.

The open access movement gains momentum with an increasing number of institutions and funders adopting open access mandates for their funded research. Consequently, an increasing amount of material becomes freely available, either from institutional repositories or from traditional or newly established journals. Libraries can play a dual role in supporting this movement: Firstly, they can provide services supporting the deposit of research output in their institutional repositories, including support for making it widely discoverable via indexes such as Google Scholar and library discovery systems. Secondly, libraries can make open access materials discoverable by their patrons through such indexes, thus expanding their collection to include materials that they would not necessarily license. This session will describe the experience of the University Libraries of Liège in Belgium and Harvard. University of Liège chose a top-down approach and made it compulsory for researchers to deposit their output in the institutional repository—ORBi. To support this mandate, the library offers services that help researchers deposit and disseminate their publications. Both libraries—Liège and Harvard—enable their students and faculty to discover open access content beyond their library’s acquired collection via their library discovery system. The session will also address challenges that arise from indexing open access publications and how index providers and libraries can deal with such publications, especially with articles that are deposited in different institutional repositories or published in so-called hybrid journals that contain a mix of open access and subscription articles. Finally, we will discuss with the audience how they see libraries’ role evolving in this area, what challenges they are currently facing, and the solutions and opportunities they have found.

Archevêque de Rouen, cardinal, légat a latere, Georges Ier d’Amboise (1460–1510) est l’une des personnalités les plus fascinantes de la première Modernité européenne. Le prélat ne s’est toutefois pas contenté de cumuler les fonctions ecclésiastiques les plus prestigieuses. Pendant une dizaine d’années, en qualité de principal conseiller de Louis XII, il fut l’artisan de la politique royale, tant en France qu’à l’étranger. Son action concerne également les arts. Que ce soit en tant que bâtisseur et amateur averti d’architecture – comme en témoigne le château de Gaillon – ou que bibliophile et collectionneur, Georges Ier d’Amboise participe résolument à la diffusion des idées et des formes venues d’Italie. Les 2 et 3 décembre 2010 – à l’occasion du 500e anniversaire de la mort du cardinal –, un colloque international a été organisé à l’Université de Liège avec le soutien de "Transitions. Département de recherches sur le Moyen Âge tardif & la première Modernité". Les actes du colloque "Georges Ier d’Amboise (1460–1510). Une figure plurielle de la Renaissance", dirigés par Jonathan Dumont et Laure Fagnart, rassemblent la plupart des contributions présentées à ce colloque et se proposent, de la sorte, de traiter les aspects politiques, religieux et culturels de la vie du prélat, ambitionnant ainsi de faire le point sur l’état de nos connaissances, tout en dégageant de nouvelles pistes de recherches.

This article presents a Time Domain Discontinuous Galerkin method applied for solving the conservative form of Maxwell equations and computing the radiated fields in electromagnetic compatibility problems. The results obtained in homogenous media for the transverse magnetic waves are validated in two cases. We compare our solution to an analytical solution of Maxwell’s equations based on characteristic method. Our results on shielding effectiveness of a conducting wall are same as those obtained from analytical expression in frequency domain. The propagation in heterogeneous medium is explored. The shielding effectiveness of a composite wall partially filled by circular conductives inclusions is computed. The proposed results are in conformity with the classical predictive homogenizations rules. [less ▲]

We investigate finite abelian groups which can represent symmetries of the N-Higgs-doublet models with quarks. We build a general formalism based on the powerful method of the Smith normal form and obtain an analytic upper bound on the order of abelian symmetry groups for any N. We investigate in detail the case N = 2 and rederive known results in a more compact and intuitive fashion. We also study the NHDM with the maximal finite abelian symmetry for all small N cases up to N = 5, and show that in each case all Yukawa textures compatible with such symmetry originate from a unique basic structure. This work opens the way to a systematic exploration of phenomenology of the NHDM with a desired symmetry, and illustrates the power of the Smith normal form technique. [less ▲]

Depuis l’invention de la caméra multiplane en 1933 par l’ingénieur Bill Garity au sein des studios Disney, jusqu’à la création de la marque Disney Digital 3-D, en 2005, qui promeut le cinéma en relief stéréoscopique, les départements des effets spéciaux de la compagnie Disney se sont fortement investis dans la quête pour une restitution impressionnante, voire spectaculaire, de la profondeur de champ. Détaillant les illusions optiques de films aussi divers que The Old Mill (1937), Snow White and the Seven Dwarfs (1937), Bolt (2008), Alice in Wonderland (2010), ou Tron : Legacy (2011), cette intervention s’interroge également sur les présupposés idéologiques du simulacre de la profondeur chez Disney, qui se trouvent par ailleurs prolongés tant dans l’architecture des parcs à thèmes Disney que dans les dispositifs de nombre de leurs attractions.
