The theta aurora is an auroral structure presenting a sun-aligned transpolar arc. Five different dynamic evolution of the transpolar arcs are known, some of them being symmetrical to each other, leaving three basically different types of transpolar auroral features. The theta aurora was previously studied with in-situ particles detectors onboard polar orbiting satellites and by ultraviolet imagers. Previous imaging works focused on the electron aurora. We use the FUV imagers onboard the IMAGE spacecraft to study separately the proton and electron contributions to the transpolar arcs at the global scale. The imagers of the IMAGE-FUV experiment remotely sense the electron aurora with the WIC and SI13 imagers observing respectively the N[SUB]2[/SUB]-LBH and OI-135.6 nm emission, while the SI12 spectrographic imager measures the Doppler-shifted Lyman-ë± emission which is solely due to the auroral proton precipitation. The three different types of transpolar aurora will be analyzed using the IMAGE-FUV imagers. In particular, the relative contribution of proton and electron to the excitation of the theta aurora will be presented. [less ▲]

Local interpretation of micro finite element (mu FE) simulations has become important in different fields of bone biomechanics. Although on an apparent level mu FE has successfully been validated against experiments, local validations are sparse and limited by imaging resolution. At the tissue level heterogeneity of Young's modulus has been reported. Although non-uniform material distribution have been shown to only have a minor influence on the apparent material properties, its impact on local material behaviour is largely unknown. By combining image-guided failure assessment (IGFA) using synchrotron-based-micro-computed tomography, strain mapping and inverse mu FE modelling, we present an experimental and computational framework which will allow studying local effects of intratrabecular heterogeneity of the Young's modulus.

In this article, a discourse analysis is presented of the tourist guides published by the ‘Patrimonio Nacional’ or National Heritage, charged with the administration and preservation of the Spanish royal sites. The analysis focuses on the guides published during the Franco era and the transition. These guides portray Spain as a nation with a deep-seated monarchist tradition, which was however usurped by the ‘decadent’ Borbon dynasty. At the same time the figure of Franco is subtly associated with the monarchy and somehow inserted in the royal imagery, both on the iconographical and textual levels. Most radically, two sites which bear no relationship with the monarchy – the Palacio de la Isla in Burgos and the Valley of the Fallen – are discursively incorporated in the royal heritage. By creating a link between Franco and the monarchist tradition, the regime attempted to enhance its legitimacy. Franco’s semi-regal status assured that his rise to power was viewed not so much as a result of a chance occurrence of circumstances but rather as a preordained succession. In the guides published during the transition, the association between Franco and the monarchy is still present, but the ideology is hidden behind a more historic discourse, a result of which Franco appears as a half forgotten historic figure.

Calcified aortic valve stenosis is the most frequent valvular heart disease in developed countries with a very poor outcome when symptoms develop. However, several of these patients are denied for surgery. The main reasons are their advanced age (elderly patient), co-morbidities, technical limitations and a very high surgical risk. It is currently possible to propose a Transcatheter Aortic Valve Implantation (TAVI). After selection of candidates, the feasibility of the intervention is analysed. The size of the aortic bioprosthesis must be selected according to the cardiac anatomy. Several cardiac imaging modalities (echocardiography, computed tomography and cardiac MRI) can be used to identify unsuitable situations. Heavy calcifications or tortuosity can thwart the retrograde approach use. The sub-clavian arteries (for the CoreValve) and trans-apical approach (for the Edwards-Sapien) constitute alternatives ways. [less ▲]

Precise brain regions are activated when a subject gives a judgment on himself. Those are the medial parietal cortex, essentially related to episodic memory processing, and the ventromedial prefrontal cortex, recruited for evaluating the personal valence of an information. These regions are not activated in Alzheimer's disease. The decrease of awareness for own deficits in a patient with Alzheimer's disease would depend on a reduction of episodic memory capacities and a worsening of judgment for self significance. [less ▲]

Electrical resistivity tomography is a geophysical method widely used for salt water intrusion studies, thanks to its ability to detect salinity contrasts. In this context, boreholes are often available to improve the interpretation of inverted models. The main objective of this study is to incorporate a priori information contained in borehole data to constrain the geophysical inversion with a geostatistical constraint based on the variogram. A synthetic benchmark showed that the choice of the prior model played a great role in the inversion process, especially in low sensitivity zones. The use of simulations conditioned with borehole data costs a lot of time because it is necessary to run several inversions to obtain a mean solution. The methodology was applied to artificial salt water infiltrations in the Westhoek nature reserve. In this case, a homogeneous prior model deduced from borehole data seemed judicious. Inversion results enabled to determine the extension of the salt water plume laterally, in depth, but also in terms of total dissolved solid content (TDS). These observations are in agreement with the hydrogeological situation of the site. A comparison with borehole data showed that the results are much more satisfying than a traditional smoothness constraint used as a regularization tool. [less ▲]

Le réseau microvasculaire de la peau joue des rôles physiologiques majeurs en oxygénant les tissus et en permettant des échanges thermiques finement régulés. Son parcours résistif et capacitif module les résistances périphériques au débit sanguin. La microvascularisation est sous l’influence de divers facteurs, mais globalement, elle semble presque immuable dans la peau saine. En revanche, certaines circonstances pathologiques engendrent des hyperplasies ou des hypoplasies vasculaires. Parfois aussi, le réseau semble garder son extension normale, mais sa structure intime est remaniée. Cette revue est un florilège d’aspects microscopiques associés à des perturbations majeures de la fonctionnalité vasculaire cutanée. [less ▲]
