In liberalized network industries, entrants can either compete for service using the existing infrastructure (access) or deploy their own infrastructure capacity (bypass). In this paper, we demonstrate that, under the threat of bypass, the access price set by an unregulated and vertically integrated incumbent is compatible with productive efficiency. This means that the entrant bypasses the existing infrastructure only if it can produces the network input more efficiently. The incumbent lowers the access price compared to the ex-post efficient level to strategically deter inefficient bypass by the entrant. Accordingly, from a productive efficiency point of view, there is no need to regulate access prices when the entrant has the option to bypass. Despite that, we show that restricting the possibilities of access might be profitable for consumers. [less ▲]

Nombre d'articles parus dans des quotidiens soulignent qu'une plus grande place devrait être faite au Sport dans l'Education. Dans cette conférence, il s'agira tout d'abord de redéfinir les différents concepts concernés avant de mettre en évidence certains paradoxes constatés à partir de résultats de recherches récentes. L'objectif consistera à mettre clairement en évidence la priorité à accorder au développement d'une culture de l'activité physique, moins sujettes aux dérapages constatés actuellement dans le développement d'un sport ultra compétitif. L'exposé se termine par la description de pistes d'actions rassemblant tous les acteurs de la société et visant à donner un visage plus accessible à la santé que l'activité physique permet de préserver.

L’insuffisance rénale avec l’âge n’est pas une fatalité. Il faut prévenir très tôt les facteurs de risque cardio-vasculaire et les corriger au mieux pour éviter que ces facteurs n’agissent plus tard dans la vie et soient des facteurs de comorbidité très importants favorisant la dégradation fonctionnelle rénale et l’évolution vers une insuffisance rénale très sévère exposant le patient à un risque cardio-vasculaire, à des techniques de suppléance de la fonction rénale et à un décès plus rapide avec perte préalable de la qualité de vie. Il faut donc identifier précocement la réduction de la GFR et l’apparition d’une protéinurie, agir de concert ensemble sur de nombreux facteurs pour ralentir la progression. Ces facteurs sont souvent des facteurs de risque cardio-vasculaire, donc on fait un double coup en les corriger. La référence précoce lorsque vous remarquez une évolutivité de la GFR vers la baisse pour décider ensemble si un traitement de suppléance doit être lancé. Celui-ci ne sera décidé qu’en concertation commune si nous avons le temps de l’établir après avoir évaluer des niveaux d’autonomie de nutrition, de risque cardio-vasculaire, et tout cela intégré dans le côté social et environnemental du patient. Il faut rappeler ici l’importance des trajets de soins à proposer à tout patient insuffisant rénal en dessous de 45 ml/min, moment stratégique pour que le néphrologue puisse en partenariat avec le médecin généraliste contrer les perturbations de l’insuffisance rénale terminale.

La notion de friction implique forcément celle de contact, ce qui, à l’évidence, intéresse au tout premier chef les images à caractère photochimique. Dans le cadre de cette communication, j'interroge la notion de friction dans le champ du cinéma d’expérimentation, en me concentrant plus particulièrement sur les films du cinéaste (et peintre) américain Paul Sharits (1943-1993). À partir de "Color Sound Frames" (1974), l’œuvre de Sharits connaît une mutation profonde. Pour une large part, le travail du cinéaste consistera désormais à refilmer des fragments de pellicule déjà impressionnés, images appartenant de facto à la catégorie du déjà-vu. Pour ce faire, Sharits mobilise un écran transparent et un projecteur trafiqué, dont il a ôté et la griffe, et le mécanisme d’obturation. Retournant l’une contre l’autre les deux machines sur lesquelles se fonde le spectacle cinématographique, procédant par « anti-cadrage » et reprise de vue, le cinéaste orchestre, au plus intime de ses œuvres, d’intenses rapports de friction entre le film second (ou film filmé) et le film premier (ou film d’accueil, celui qui se déroule sous nos yeux) ; il accuse, de manière très méthodique, les discordances qui affectent les deux niveaux de la représentation, que ce soit en termes de vitesse, de texture ou de stabilité des motifs. Ma communication se donne pour but d’étudier, dans tous ses enjeux, les frictions internes qui traversent les films tardifs de Paul Sharits, dont "Tails" (1976) et "Bad Burns" (1982). Dans le cas de ce dernier film, le rapport de friction s’exacerbe, se déporte et tourne au conflit ouvert entre l’image et la source lumineuse censée lui donner vie : il se solde ponctuellement par des destructions apparentes du support filmique, petits désastres figuratifs qui ont paradoxalement valeur, selon Sharits, d’actes analytiques à part entière.

The basic principle adopted in our studies is to use substrate limitation responsive biosensors in order to detect spatial glucose heterogeneities inside industrial bioreactors (whole-cell biosensor). Indeed, such heterogeneities cause a lowering of the biomass yield and an increase of by-products concentration. In this work, we have used these biosensors for the elaboration of a mini-bioreactor platform that can be used as a scale-down tool. Three green fluorescent protein (GFP) transcriptional reporters have been chosen in Escherichia coli, i.e. uspA::gfp, csiE::gfp and yciG::gfp. Our previous studies have shown that these kinds of promoters are induced in response of substrate limitation and exhibit a strong fluorescence attenuation when cultivated in heterogeneous bioreactors. This sensitivity to substrate limitation has been confirmed in the case of the csiE and yciG biosensors. A mini scale-down platform has been proposed as a high throughput tool to investigate rapidly the usefulness of a given microbial biosensor. This platform is composed of shake flask able to operate in fed-batch mode either by using the slow release or the intermittent feeding principle. The first system is based on a commercial package (Enbase) based on the enzymatic release of glucose in the medium. The Enbase system allows the generation of a very smooth glucose profile without any perturbations. For comparison purpose, we have also used an intermittent feeding that induces strong fluctuation at the level of the glucose and the dissolved oxygen concentration. Local heterogeneities have thus been reproduced at the level of these mini-bioreactors and these one have caused a decrease of GFP expression, as in conventional scale-down reactor. The presence of GFP in supernatants has also been noticed and seems to be correlated with the substrate limitation signal for the three cultivation systems considered in this work (i.e., chemostat, conventional and mini-bioreactors) and with the membrane permeability.

Computerized adaptive testing (CAT) is an efficient method to administer psychometric or educational tests and questionnaires. Unlike the standard fixed (“paper-and-pencil”) tests, items in a CAT are iteratively and optimally selected within a bank of available items, on the basis of previously administered items and the current ability estimate of the examinee. This general approach has several assets with respect to fixed tests: it reduces the risk of fraud, it allows for individualized questionnaires according to the examinee’s ability level, and fewer items must be administered to reach the same level of precision in the ability estimates. The purpose of this talk is threefold. First, a general overview of CAT is proposed and its main principles are quickly outlined. Second, a recently developed R package, called catR, is briefly presented and its functionalities are described. Finally, two applications are discussed. The first application is a live demonstration of catR, by using its by-default item bank about English aptitude assessment, and several CAT options. The second application focuses on the on-line testing platform Concerto, a web interface for the development and testing of CAT sessions that uses catR as underlying computational package. The R package catR was jointly developed with Gilles Raîche (Université du Québec à Montréal, Canada). The platform Concerto is under development by The Psychometrics Centre (Cambridge University, UK) under the supervision of Michal Kosinski and John Rust. [less ▲]

Particle acceleration and non-thermal emission processes in colliding-wind massive binaries constitute key issues in massive stars physics. The investigation of such processes requires a good knowledge of their stellar, stellar wind and orbital parameters. In this short contribution, I will present the latest results related to the case of HD167971, a system recently resolved by the VLTI. The information on the separation and on the luminosity ratio derived from these observations will also be discussed in the context of the so-called 'standard scenario' for particle acceleration and non-thermal processes in massive stars.

The bulk morphology of Jupiter's and Saturn's UV aurorae is conveniently divided into three components: 1) the main emission (main oval), 2) the satellites auroral footprints (equatorward of the main emission): Io, Europa and Ganymede for Jupiter and Enceladus for Saturn, 3) the polar emissions (poleward of the main emission).This schematic view is already providing useful information on the giant planets aurorae. However, a quick inspection of HST and Cassini UV images directly shows that this simplified classification does not really match the complex morphology of the auroral emissions. As an example, in the case of Jupiter's UV aurorae, it appears that the main emission is not forming an oval, not even a closed shape; it is far from uniform and its position and size vary with time and depend on the viewing geometry. A secondary emission appears equatorward of the main emission and many small scale features regularly appear, some of them periodically. Satellites auroral footprints themselves appear to be much more intricate than predicted by present models. These footprints are actually multiple, their location and number vary periodically with time and with the satellites orbital longitude. The polar emissions are also much more complicated than predicted. Each of the above effects is related to a specific physical phenomenon in the atmosphere, the magnetosphere, or even in the planet's interior. For instance, the spatial distribution of the satellites auroral footprints made it possible to demonstrate the existence of a magnetic field anomaly near the surface of Jupiter's northern hemisphere. Observations which might appear insignificant, like the multiplicity of the satellites footprints or their periodicity are actually extremely valuable because they reveal the complexity of the interaction, in this case between a moon and the magnetospheric plasma of the planet around which it is orbiting. The same applies to small scale auroral structures which depict crucial magnetospheric processes like hot plasma injection, flux-tube interchange or magnetic reconnection mechanisms. The growing HST and Cassini databases are shedding new light on the origin of Jupiter's and Saturn's aurorae. Mechanisms that we thought could be taken for granted may even be challenged. [less ▲]

It is well known that high latitude zones are very sensitive to climate change. As a result of global warming, ice sheet melting has increased which in turn has an influence on climate through modifications of the thermohaline circulation, feedback of ice albedo, sea level rise,. . . Svalbard is an archipelago located between 74 and 81◦ lat N and 60 percent of its area (62 248 km2 ) is covered with glaciers and ice sheets. The impact of global warming on the Svalbard cryosphere can be estimated with climate models. However, we need to use regional climate models as they offer the possibility of a higher resolution than general circulation models. We have carried out a simulation of the Svalbard climate over the last 50 years (from 1958 to 2010) with the regional climate MAR model (tuned for the Greenland ice sheet) at a 10 km resolution forced with the ECMWF reanalysis. As validation, the modeled climate has been compared to near surface measurements at several weather stations through the archipelago. The results show a large interannual variability of the surface mass balance over Svalbard along with an increasing melting. The increase in temperature is responsible for the melting rate and the interannual variability is due to the variations of the mean summer temperature. [less ▲]

The postglacial re-colonization of Europe by temperate tree species from a few glacial refugia during the Holocene (10,000 BP) is a very interesting case to study the mechanisms of the vegetation dynamics. The relative roles that played the climate conditions, the species dispersal capacities and the competition between species in the re-colonization rates remain controversial. We investigate these different aspects with the CARAIB dynamic vegetation model (CARAIB DVM). Transient runs were performed over the Holocene using the HadCM3 AOGCM-reconstructed climate. European-wide species migration at 0.5° x 0.5° is represented in the model using migration rates derived from a high resolution cellular automaton, CATS-UPSCALE. Individual tree species migration rates were pre-calculated with CATS-UPSCALE every 1000 years over each grid cell used by the DVM in the climatic conditions reconstructed by the AOGCM. The impacts of competition on plant dispersal are not taken into account by the automaton. Thus, in CARAIB, a function has been constructed to reduce the potential CATS migration rates in competition conditions. It is based on the species dispersal kernel and on the net primary productivity of the different species present on the grid cell. The migration of one species, from its 10,000 BP refugia, is studied within a landscape defined by a set of other species for which no dispersal limitations are assumed. Here, we illustrate the results obtained for two wind-dispersed (Abies alba and Picea abies) and for a no wind-dispersed (Fagus sylvatica) tree species. The speeds and the paths of the postglacial spread obtained with the DVM are compared to the past distributions of the three species reconstructed from pollen and macrofossil data. The Holocene climate conditions simulated by the HadCM3 AOGCM do not constrain the European re-colonization of the studied species, except in Scandinavia at the beginning of the period for Picea abies. We observe that, during the past 10,000 years, species occupied regions where climate conditions were different from present observed species climate requirements, notably in the 10k species refugia. This result may imply that at present the species do not occupy their potential distribution area and thus that the postglacial re-colonization is not completed yet. We also show that species dispersal capacities cannot explain the observed species migration over the Holocene and that competition has played an important role. Indeed, when we use the potential migration rates (no competition), species spread too fast. [less ▲]

Today, state-of-the-art simulation packages in flexible multibody dynamics allow the high-fidelity analysis of industrial mechanisms and machines in many application fields including robotics, automotive systems, aeronautics, deployable structures or wind turbines. The dynamic response of a given system can thus be evaluated in the time-domain for given load cases and given initial values. However, in many practical cases, the engineer does not have a precise knowledge of the mechanical design, the loading conditions and the initial state. This situation occurs for example in structural optimization, optimal control, experimental identification and health monitoring problems. The complexity of simulation codes and the computational cost of high-fidelity models are still important obstacles for the development of efficient resolution methods for these inverse problems. A current challenge is thus to elaborate simplified and more efficient modelling strategies in flexible multibody dynamics in order to enable the development of inverse analysis methods. The talk is divided into three parts. The first part provides an overview of available simulation techniques for flexible mechanisms with a particular emphasis on finite element-based approaches and time integration methods. Some illustrations are presented in the fields of deployable structures, vehicle dynamics and wind turbines. In the second part, optimization problems in flexible multibody dynamics are addressed and solved using gradient-based methods. Efficient methods for sensitivity analysis are discussed and special problems are treated such as the structural optimization of mechanical components or the numerical solution of inverse dynamics problems. The third part discusses a recently-developed Lie group approach which allows the formulation of the equations of motion of a multibody system in a parameterization-free setting. Based on this general formalism, which is characterized by an increased modularity and a reduced complexity, a large variety of Lie group solvers are foreseen not only for time integration but also for model reduction, sensitivity analysis and optimization.

In this paper, we try to estimate some statistics about the decision making process in a bistable model submitted to noise by studying the local properties of the system around an hyperbolic saddle point. Despite the fact that the saddle is not an equilibrium point of the stochastic system, we show that a local approach is still instructive. Under appropriate assumptions, the system can be reduced to an Orsntein-Uhlenbeck process whose dynamics depend on the properties of the saddle point. Yet, Orstein-Uhlenbeck processes have been used to study decision making under uncertainty in a broad variety of fields including statistics and cognitive neurosciences . [less ▲]

As his star-spangled costume and his usually firm posturing suggest, Uncle Sam impersonates the United States and symbolically reflects the nation’s most cherished values and ideals such as freedom, exceptionalism, and (masculine) strength. As such, he connects the projects of nationalism and patriotism with the scale of the individual. In other words, he embodies the American motto ‘out of many, one.’ Steve Darnall and Alex Ross’s rewriting of the character, however, strongly contrast with this dominant perception of Uncle Sam in their eponymous 1997 graphic novel. Their narrative shows a distressed and lunatic homeless man wandering the streets of an unknown American city. As he roams the streets, he undergoes an identity crisis that coincides with a crisis of memory, both of which complicate the relation between the symbolic individual body and the collective American unconscious. On the one hand, the character represents the values of freedom and democracy that the US government has strived to implement. On the other, he realizes that the paradigm of the nation cannot be understood as a monolithic entity, and that the plurality of voices that inhabit his persona – and, quite paradoxically, the country – cannot uphold this meta-narrative of American unity. In asking whether or not Uncle Sam is one of U.S., Darnall and Ross comment on the paradoxes of freedom and the myth of the melting pot. [less ▲]

Within the specialist seminar, the aims of this presentation were to share a personal conception of Sport (& Exercise) Pedagogy, to illustrate some current challenges for researchers of this specific field of Sport Sciences, and to suggest some approaches to develop in the future. In the first part, an emphasis will be set on the analysis of the papers presented during the ARIS' congresses. It will be the opportunity to bridge the gap between Anglo-Saxon authors and those from the French speaking world, in order to underline the existence of a research corpus that is unknown by those who are not able to read another language than English.

Methods validation is mandatory in order to assess the fitness of purpose of the developed analytical method. Of core importance at the end of the validation is the evaluation of the reliability of the individual results that will be generated during the routine application of the method. Regulatory guidelines provide a general framework to assess the validity of a method, but none address the issue of results reliability. In this study, a Bayesian approach is proposed to address this concern. Results reliability is defined here as “the probability ()π of an analytical method to provide analytical results within predefined acceptance limits ()X()λ± around their reference or conventional true concentration values ()Tμ over a defined concentration range and under given environmental and operating conditions.” By providing the minimum reliability probability (minπ needed for the subsequent routine application of the method, as well as specifications or acceptance limits ()λ±, the proposed Bayesian approach provides the effective probability of obtaining reliable future analytical results over the whole concentration range investigated. This is summarized in a single graph: the reliability profile. This Bayesian reliability profile is also compared to two frequentist approaches, the first one derived from the work of Dewé et al. [1] and the second proposed by Govaerts et al. [2]. Furthermore, the applicability of the Bayesian reliability profile is shown using as example the validation of a bioanalytical method dedicated to the determination of ketoglutaric acid (KG) and hydroxymethylfurfural (HMF) in human plasma by SPE-HPLC-UV.

Since the end of the eighties, the globalization and development of new information and communication technologies have played a great part in complicating exchanges between companies and their various stakeholders (staff, customers/users and business partners). New forms of organization of work result in more and more relationships between people of different nationalities and cultures. Thanks to virtuality, a lot of companies can develop connections with people from various cultural backgrounds which can be co-located or distributed (with partners situated abroad, including in different time zones). But to maximize this potential, organization must overcome different complexifications levels of virtual communication and multicultural. So, we suggest studying the impact of cultural diversity on the quality and efficiency of virtual communications. There are already many studies about the impact of diversity on non-virtual context but very little about the impact of diversity on virtual exchanges. The originality of this article is to focus on the influence of intercultural and virtuality. [less ▲]

As part of the ICE2SEA project, the regional climate model MAR was forced by the global models HadCM3 and ECHAM5 for making future projections of the Greenland Ice Sheet (GrIS) Surface Mass Balance (SMB) over 1980-2099 at a resolution of 25km. However, the comparison with MAR forced by the ERA-40 reanalysis over 1980-1999 shows that MAR forced by these GCMs is not able to represent reliably the current SMB due to biases in the general circulation and in the free atmosphere summer temperature modelled by these GCMs around the GrIS. <br /> <br /> That is why, we present here first results of MAR forced by the next generation of GCMs from the CMIP5 data base (CanESM2 and NorESM1 here). The comparison with the ERA-40 forced MAR simulations over current climate is a lot of better, which increases the reliability and the interest of these new MAR projections. In addition, the new scenarios (RCP 2.6, 4.5, 6.0 and 8.5) of the next IPCC Assessment Report (AR5) are used here. These new simulations show notably that the response of SMB to rising temperature is not a linear function of the temperature anomalies due to the positive albedo feedback which accelerates the surface melt. For 2100, in case of extreme rising temperature (RCP 8.5 scenario), MAR simulates a surface GrIS mass loss corresponding to a cumulated sea level rise of about 15 cm since 2000! Mainly the changes in SMB and in surface energy balance will be discussed here. [less ▲]
