In multinational federations, identities are a chief variable of the political life. By definition, the ethno-linguistic identities play(ed) an important role in the federal dynamics of the country. In most cases, the institutional design is in fact adapted or has been adapted to the ethno-linguistic divisions of the country. According to quite a few scholars, it is especially true for political elites who are not only shaped by this variable but also use this variable to legitimate their attitudes and actions. Therefore political elites of each ethno-linguistic group appeared to behave as monolithic blocks, standing against each other along ethno-linguistic lines. Nonetheless, this view neglects the role of party interests in explaining the behaviors of political elites. An important question for multinational federations can be raised: do identities matter more that party interests? The current reform of the Belgian state provides a fertile ground to test this hypothesis. To what extent, party interests can account for political elites’ position in the debate about the 6th Belgian constitutional reform? To explore these questions, we surveyed every representative of Belgium’s seven legislative assemblies with a standardized questionnaire (Summer 2011). This research will help us apprehend the rationale behind political elites’ attitudes – be it identities, party interests or a mix of them – negotiating the new boundaries of the state. [less ▲]

At room temperature, the local structure of crystalline group V elements (As, Sb,middotmiddotmiddot) and their IV-VI isoelectronic compounds (GeSe,middotmiddotmiddot) is governed by a Peierls distortion of the simple cubic or NaCl structure which is a symmetry breaking electronic instability. The morphology of the distortion is determined by the filling ratio of the p-band; for a half-filled p-band, the sixfold coordination becomes 3 (short, covalent) +3 (long, van der Waals). In general, at high temperature, the structure recovers its higher coordination number. Neutron diffraction experiments have been made in the liquid state at lambda=0.7 Aring. It is observed that the Peierls distortion is still present in the liquid for most IV-VI compounds. This behavior is observed and discussed for a series of Sn and Ge chalcogenides: SnS, SnSe, GeS, GeSe and GeTe and their temperature evolution is discussed. GeSe and GeTe show an interesting re-entrant phase behavior. The heaviest IV-VI compound SnTe does not show a distorted state. We demonstrate that the hardness of the repulsive potential is a key parameter in this mechanism [less ▲]

Recent electron microscopic immunolocalization studies (Scheer and Rose, 1984) indicated that RNA polymerase I is located in, and probably confined to, the fibrillar centres of the nucleoli. This conclusion appears to be in contradiction to previous autoradiographic studies reporting that transcription of rRNA genes takes place in the dense fibrillar component. Despite the fact that rRNA transcription occurs in the dense fibrillar component of Ehrlich tumour cell nucleoli, we show in the present paper that dense fibrillar component containing rapidly labelled RNA can be visualized not only around but also inside the fibrillar centres.

These days authors who use stereotypical characters such as the African woman warrior or the old field slave smoking his pipe and humming blues songs, would probably be considered as intellectually biased or mentally colonized. Yet, it is also the case that, for some African American writers like Amiri Baraka, Charles Fuller and Lorraine Hansberry, these characters represent a link between Black people and their past or, to use Pierre Nora’s term, they are lieux de mémoire. This is why these authors oppose the more or less general attitude which consists in dismissing these clichéd-figures from the field of representation, for this would amount to erasing an entire the inception segment of African American history. Going against the trend of the time, these playwrights thus give a voice to those silenced by normative history and, to decolonize symbols which after all belong to the past of Black people, Baraka in The Slave (1964), Fuller in A Soldier’s Play (1981) and Hansberry in Les Blancs (1966) also invest these characters with a new significance.

In injection moulding processes such as Resin Transfer Moulding (RTM) for example, numerical simulations are usually performed with a fixed mesh, on which the displacement of the flow front is predicted by the numerical algorithm. During the injection, special physical phenomena occur on the front, such as capillary effects inside the fibre tows or heat transfer when the fluid is injected at a different temperature than the mould. In order to approximate these phenomena accurately, it is always better to adapt the mesh to the shape of the flow front. This can be achieved by implementing re-meshing algorithms, which will provide not only more accurate solutions, but also faster calculations. In order to represent precisely the shape of the saturated domain in the cavity, the mesh needs to be non-isotropic in the vicinity of the flow front. The size of the elements along the front is connected to the overall accuracy needed for the simulation; the size in the perpendicular direction governs the accuracy on the position of the moving boundary in time. Since these two constraints on element size are not related, the need for non-isotropic mesh refinement is crucial. In the approach proposed here, the mesh is changed at each time step from a background isotropic mesh used as starting point in the refinement algorithm. The solution needs to be projected on the new mesh after each re-meshing. This amounts to adopting a new filling algorithm, which will be validated by comparison to a standard simulation (without re-meshing) and with experimental data. [less ▲]

Today, there are many finite element simulation software on the market. The main issue when developing a new application of the finite element method is not solving the linear systems that arise from the numerical approximation, but it is rather to construct the mesh and adapt it to the problem. Mesh generation, in the sense of modelling the geometry constraints, still remains a big problem. In this communication, however, we will not deal with initial mesh generation, but rather about mesh modifications applied to a time evolving problem, namely a mould filling simulation. In injection moulding processes, in particular in resin transfer moulding, the simulations are usually preformed with a fixed mesh at each time step. During the displacement of the resin flow, there are phenomena that occur at the front, such as heat transfer. In order to catch them accurately, it is necessary to follow the front flow with the mesh. This implies to implement a re-meshing algorithm. By using this technique, it will be possible to obtain much better results in less time, compared to fixed mesh strategy. The mesh will need to be anisotropic in the vicinity of the front. The size of the mesh along the front is related to the overall accuracy needed for the simulation. The size of the mesh in the perpendicular direction is related to the time accuracy, as the front is moving forward. Those sizes are not related, thus the need for anisotropic mesh procedures is crucial. The mesh will be evolving in the time. For that purpose, we will keep a background isotropic mesh used as starting point for the refinement at every time step. Then, it will be refined anisotropically. The physical field of solution needs to be projected on the new mesh, each time a re-meshing occur. Finally, some validation is needed, first with the standard simulation procedure (without remeshing), then with experimental data. [less ▲]

Disorders of consciousness (DOC) raise profound scientific, clinical, ethical, and philosophical issues. Growing knowledge on fundamental principles of brain organization in healthy individuals offers new opportunities for a better understanding of residual brain function in DOCs. We here discuss new perspectives derived from a recently proposed scheme of brain organization underlying consciousness in healthy individuals. In this scheme, thalamo-cortical networks can be divided into two, often antagonistic, global systems: (i) a system of externally oriented, sensory-motor networks (the "extrinsic" system); and (ii) a system of inward-oriented networks (the "intrinsic" or default system). According to this framework, four distinct mental states would be possible that could be relevant for understanding DOCs. In normal healthy volunteers and locked-in syndrome patients, a state of high functionality of both the extrinsic and intrinsic or default systems is expected--associated with full awareness of environment and self. In this case, mental imagery tasks combined with fMRI can be used to detect covert awareness in patients that are unable to communicate. <br /> <br />According to the framework, two complementary states of system imbalance are also possible, in which one system is in a hyperfunctional state, while the other is hypoactive. Extrinsic system hyperfunction is expected to lead to a state of total sensory-motor "absorption" or "lost self." In contrast, intrinsic or default system hyperfunction is expected to lead to a state of complete detachment from the external world. A state where both extrinsic and intrinsic systems are hypofunctional is predicted to lead to markedly impaired consciousness as seen in DOCs. Finally, we review the potential use of ultra-slow fluctuations in BOLD signal as a tool for assessing the functional integrity of extrinsic and intrinsic systems during "resting state" fMRI acquisitions. In particular, we discuss the potential provided by assessment of these slow spontaneous BOLD fluctuations as a novel tool in assessing the cognitive state and chances of recovery from brain pathologies underlying DOCs.

Asteroseismic modeling of subdwarf B (sdB) stars provides measurements of their fundamental parameters with a very good precision; in particular, the masses and radii deter- mined from asteroseismology are found to typically reach a precision of 1% containing various uncertainties associated with their inner structure and the underlying microphysics (composition and transition zones profiles, nuclear reaction rates, etc.). Therefore, the question of the accuracy of the stellar parameters derived by asteroseismology is legitimate. We present here the seismic modeling of the pulsating sdB star in the eclipsing binary PG 1336-018, for which the mass and the radius are independently and precisely known from the modeling of the reflection/irradiation effect and the eclipses observed in the light curve. This allows us to quantitatively evaluate the reliability of the seismic method and test the impact of uncertainties in our stellar models on the derived parameters. We conclude that the sdB star parameters inferred from asteroseismology are precise, accurate, and robust against model uncertainties. [less ▲]
