Genetic variability related to the catechol-O-methyltransferase (COMT) gene (Val158Met) has received increasing attention as a possible modulator of executive functioning and its neural correlates. However, this attention has generally centred on the prefrontal cortices because of the well-known direct impact of COMT enzyme on these cerebral regions. In this study, we were interested in the modulating effect of COMT genotype on anterior and posterior brain areas underlying interference resolution during a Stroop task. More specifically, we were interested in the functional connectivity between the right inferior frontal operculum (IFop), an area frequently associated with inhibitory efficiency, and posterior brain regions involved in reading/naming processes (the two main non-executive determinants of the Stroop effect). The Stroop task was administered during fMRI scanning to three groups of 15 young adults divided according to their COMT Val158Met genotype [Val/Val (VV), Val/Met (VM) and Met/Met (MM)]. Results indicate greater activity in the right IFop and the left middle temporal gyrus (MTG) in homozygous VV individuals than in Met allele carriers. In addition, the VV group exhibited stronger positive functional connectivity between these two brain regions and stronger negative connectivity between the right IFop and left lingual gyrus. These results confirm the impact of COMT genotype on frontal function. They also strongly suggest that differences in frontal activity influence posterior brain regions related to a non-executive component of the task. Especially, changes in functional connectivity between anterior and posterior brain areas might correspond to compensatory processes for performing the task efficiently when the available dopamine level is low.

Mesoporous crystalline hematite is a material difficult to prepare by soft-templating with conventional techniques, because of its high crystallization temperature associated to the crystal-to-crystal goethiteto-hematite phase transition. In a previous work, it has been reported that with very careful calcination steps, it is possible to prepare mesoporous hematite films with the spin-coating technique. However, with less conventional techniques such as surfactant-assisted ultrasonic spray pyrolysis, the deposition usually leads to non-porous oxide films or to films with interstitial porosity. In this work, we demonstrate for the first time the proof-of-concept of block-copolymer templating of hematite thin films by the ultrasonic spray pyrolysis technique. Despite the fast thermal decomposition during spray deposition, a regular, monodisperse packing of spherical pores is observed after deposition on pre-heated substrates (250 C) and after a careful post-annealing step at 470 C. Moreover, with the use of a silica scaffold, we successfully preserved porosity up to a temperature as high as 800 C. These films are highly crystalline and they are composed by randomly oriented nanocrystallites with sizes as small as 25 nm. Furthermore, we show that the crystallization evolution with temperature is influenced by the presence of the templating agent and also by the preparation technique. [less ▲]

The present paper addresses the problem of modal identification of time-varying systems. The identification is based on a multivariate autoregressive moving-average model in which the time variability of the system is caught using a basis functions approach. In this approach, the time-varying regressive coefficients in the model are expended in the chosen basis functions and only the projection coefficients have to be identified. In that way, the initial time-varying problem then becomes a time-invariant one that can be solved. Because a multivariate model is used, in addition to the time-varying poles, the time-varying mode shapes may be identified too. The method is first presented and then applied on an experimental demonstration structure. The experimental structure consists of a supported beam on which a mass is travelling. The mass is chosen sufficiently large to have a significant influence on the dynamics of the primary system. This kind of problem is a classical example commonly used by many authors to test time-varying identification methods. [less ▲]

The international conference « encore l'architecture – encore la philosophie » is an initiative of the GERPHAU lab, research group for Philosophy, Architecture, Urban (Architecture School of Paris La Villette, UMR 7218 CNRS-Lavue), in partnership with Cité de l'architecture et du patrimoine, UMR-Lavue (Laboratoire Architecture, Ville, Urbanisme, Environnement) and philAU (a scientific thematic network : Philosophy, Architecture, Urban). This conference is the first ARENA conference (Architectural Research in Europe Network Association), a shared platform that aims to promote, support, develop and disseminate high-quality research in all fields of architecture in the widest sense. The network already includes researchers from leading European architecture schools. Synopsis. In Paris in 1987, a first event was held to celebrate the meeting of two disciplinary fields, entitled “Mesure pour mesure, architecture et philosophie”. Architects and philosophers were invited to discuss together how philosophy could capture better what determines architecture itself. Now, on the occasion of a new international conference, the GERPHAU Lab seeks to restate and refresh the question of the meeting of architecture and philosophy, by asking: what still remains today of our cross-over practices? ENCORE L'ARCHITECTURE, ENCORE LA PHILOSOPHIE. To build together these reflections about the future of our respective practices, why don't we hold to the hypothesis that our recent histories, in architecture as well as philosophy, could be written through the addition of a few prefixes? In linguistics, a prefix does not only serve the formation of a new word: it also regenerates the question of the meaning of the word. It is a discursive invention and its real strength lies in its ability to engage a new type of relationship with the world. Re-, alter-, eco-, co-, bio-, etc., these prefixes have clung to both our discourses as well as our disciplines. But in what way do they question the meaning of our practices? In archi-tecture as in philo-sophy, how do these successive re-definitions put the fundamentals into question, and how do they disturb their alleged unity inherited from Ancient Greece? And, moreover, how does the over-use of prefixes help us to understand what still makes sense in philosophy, or what still makes sense in architecture? The key issue of this conference, ‘Encore l'architecture, Encore la philosophie’, will be to trace backwards the stream of architectural and philosophical ideas through the thematic of the prefix as constituting a form of narrative. The conference will aim to trace the paths of their development, and other influencing factors, so as to return to those meetings between architecture and philosophy which already have oriented, re-oriented and sometimes dis-oriented our speech. It will be a meeting at which we invite participants to retell the story of our disciplines in order to grasp what it is still unique today about our practices. [less ▲]

Dans cette proposition d'article, il sera question de mettre en avant l’originalité et la pertinence de l’approche de Cuesta en tant que lieu de recherche non-institutionnalisé, à partir d’une expérimentation actuellement menée sur le territoire rennais. Cuesta est une structure coopérative récemment formée par une urbaniste et une productrice, et dont l'objectif est de faire intervenir les processus artistiques en amont des projets d'aménagement, pour leur permettre d'impacter sur ceux-ci. Cet article proposera alors une « relecture » des intentions de Cuesta à partir de la théorie politique du philosophe américain, John Dewey, afin de voir comment considérer ce type de travail comme la mise en place de dispositifs d'enquête visant à reconstruire un cadre spécifique d'expérience pour qu'un public puisse s'auto-constituer autour de problématiques situées. De ce croisement entre théorie et pratique, le but sera d'interroger les logiques de constitution du laboratoire au regard de cette approche innovante considérée comme nouveau type de recherche territoriale.

Comment observer le monde en transformation ; comment représenter et se représenter le monde toujours déjà pris dans sa transformation ? Il ne s'agira pas ici de répondre à ces questions, mais de travailler avec elles. Pas de solution inéluctable ni d'annonce de savoirs inédits, juste une déclinaison de ces questions à travers différents champs et pratiques de pensées. Si ces questions de représentation se sont déjà engagées dans le domaine des savoirs cartographiques, il y a à présent lieu de forcer pour d'autres leur traduction, d'abord artistique et ensuite, peut-être, architecturale.

One of the questions raised by the meeting of these two practices is about the nature of this interaction soccer-advertising. When scrutinizes closely, one realizes that advertising discourse that unfolds on the football field seems to strive to incorporate into its narrative codes of this discipline, it tries to reshape at will to fulfill its own pragmatic goals, which are registered in an argumentative persuasive Contract type opposite to those of football, which basically works based on a dichotomous rhetoric and diagram of the test. This can be seen especially through the exploitation by advertisers of functional units of the footballing universe, such players, the ball, the view of the stadium, etc., which they associate with their products. Our work intend to identify and describe the semiotic structures through which football-advertising encounter takes place, so to realize this duplication. We focus on football stadiums. [less ▲]
