Stall flutter is an important undesirable phenomenon affecting lifting surfaces such as helicopter and wind turbine blades, but is particularly difficult to model. Existing methodologies are not universally applicable, and have significant limitations concerning applicability, time of computation and accuracy. This paper presents a method that combines interactive boundary layer with point vortex shedding. It is applied to a NACA0012 airfoil, at different angles of attack in the −40◦ < a < 40◦ range, considering a free flow velocity of 20[m/s]. Results are compared to those obtained at the Goldstein Laboratory of the University of Manchester. [less ▲]

This paper presents a special beam finite element accounting for a possible deformation of the cross section of the member. The element is based on the superposition of a classical beam displacement field and of a local field describing local effects, with an approximation on the local second order membrane stress field. The methodology is presented as an efficient alternative solution to shell FE models. It is applied to the analysis of profiles with rectangular hollow section susceptible to both global and local buckling. Different kinds of analyses are presented (computation of critical bifurcation loads, geometrically non linear analysis, geometrically and materially non linear analysis) [less ▲]

The present study has for objective to introduce, during the sketch design, a rational method of aiding to design the envelope of a building, targeting the respect of costs (for the construction and in use of the building) and the improvement of the energy performance of the project. In respect of the multicriteria and multiactors context of any building project, an interactive tool is being developed, which is using decision-making aids, in order to improve the architectural response to the client’s and regulations requirements, while aiding; - the client: in the expression of his requirements and in his participation to the multiple partners negotiation; - the project authors: in their elaboration of the parametric and graphic forces of the architectural project, they can develop in accordance with the actors’ objectives. Permanently informed about the project performances, the user may go, as he pleases, in the parametric or in the graphic module, in order to reach the most preferred compromise. [less ▲]

The PC software AMCE proposes building actors a Multiple Criteria Decision Aid procedure (MCDA) to optimise the building envelope about cost and energy performances, during the sketch design. Two main modules are linked, where the user interactively goes: - a first one manages parameters describing the project requirements; - a graphic pen-based module allows to draw the sketch; it calculates geometric parameter values and put them back in the first module. Permanently informed on foreseeable performances, the user can any time search for optimal scenario giving best satisfaction to one actor or most preferred compromise to the set of actors. [less ▲]

The PC software AMCE is proposing building actors (owner, project authors...) a Multiple Criteria Decision Aid (MCDA) procedure to optimise the building envelope about cost and energy performances, during the sketch design, when most important choices are fixed, those having impact on future building's cost and use. Two main modules are linked, where any actor interactively goes in any time: - the first one manages parameters describing the project requirements; - the graphic pen-based module allows to draw the sketch; it calculates geometric parameter values and puts them back in the first module. Permanently informed on foreseeable performances, the user can any time search for optimal scenario giving best satisfaction (monoactor optimisation) or most preferred compromise (multiactors optimisation): at his disposal, he has at lot of graphs illustrating the performance sensitivity to parameter variations, as well as an optimisation procedure using a genetic algorithm to find the most efficient parameter set.

While we agree that the frame problem, as initially stated by McCarthy and Hayes (1969), is a problem that arises because of the use of representations, we do not accept the anti-representationalist position that the way around the problem is to eliminate representations. We believe that internal representations of the external world are a necessary, perhaps even a defining feature, of higher cognition. We explore the notion of dynamically created context-dependent representations that emerge from a continual interaction between working memory, external input, and long-term memory. We claim that only this kind of representation, necessary for higher cognitive abilities such as counterfactualization, will allow the combinatorial explosion inherent in the frame problem to be avoided. Introduction You live in a tidy little suburb of America. You call up a friend and invite him to have a drink. He agrees to meet you at seven. But then, just before you hang up, he adds, 'Unless my wife has scheduled something else for this evening.' You think: that's reasonable. Then he adds, 'Unless the bar doesn't exist anymore.' You think: that's a bit strange since the bar was there three months before. Then he adds, 'Unless I'm killed on the way there.' You begin to wonder if you really want to have a drink with him. And finally, he adds, 'Unless a meteorite destroys the earth' and you suddenly remember a prior engagement. But what, exactly, makes some of these conditions perfectly reasonable, others crazy? The philosophical problem is that we cannot exclude any of them a priori because contexts do exist in which they would be perfectly appropriate remarks. For example, if the bar in question was a theme bar devoted to punk rock music, or if the conversation had occurred in London in 1942 or in Sarajevo fifty years later, or if on that day the earth happened to be passing through a dense band of meteorites the size of Madagascar....

The Ets factors are a family of 27 transcription factors characterized by their unique DNA-binding domain, the ETS domain. We aimed at building a protein-protein interaction (PPI) map (interactome) of the human Ets factors in order to better define their roles and regulations in normal and oncogenic processes. The Ets interactome was built on a high-throughput yeast-two hybrid (Y2H) approach, and a literature and database curation of confident interactions which led us to the identification of 602 PPIs and 369 different protein partners. Clusterization using the Network Analysis Tool box (NeAT) divided the ETS interactome into 39 functional sub-networks. Among these, we identified Cluster16 as highly connected to the Erg ETS subfamily. A gene ontology (GO) enrichment analysis revealed that Cluster16 was associated to various aspects of mRNA processing. We therefore hypothesized that Erg factors might have a role in post-transcriptional gene regulation. This would constitute a entirely new and undisclosed role for ETS factors, which are so far firmly established as transcription factors. In support of our hypothesis, we observed that ERG localized in p-bodies, cytoplasmic sites of mRNA decay. Interestingly, under various cellular stresses, a portion of ERG and its partners from Cluster16 localized in stress granules, cytoplasmic sites of mRNA silencing physically linked to p-bodies. Hence, we hypothesized that Erg proteins might be involved in cellular mRNAs degradation. To test this, we performed a MS2-based tethering assay and showed that the recruit-ment of Erg factors promoted degradation of a reporter mRNA, mainly via its N-ter domain. Very importantly, oncogenic TET-Erg fusions described in AML and Ewing’s sarcoma exhibited diminished ability to degrade target mRNAs, concomitantly with the loss of the N-ter domain of the corresponding Erg protein. This re-inforces the important role of Erg proteins in mRNA degradation in cancer. Our efforts are now concentrated on identifying the molecular determinants behind this new function of Erg proteins.
