In the framework of EU FP7 BRICKER project, the renovation of public owned nonresidential buildings is addressed through the installation of innovative passive and active technologies. The expected impact is a primary energy reduction of about 50% with respect to the existing scenario with a large replication potential under different European countries. In order to achieve such ambitious goal one issue that cannot be ignored is the effect of control strategy, not only over the resulting energy performance but also over the resulting indoor comfort conditions. In this paper, the actual control strategy implemented in the Belgian demo of Bricker project is introduced, compared against an ideal approach and accordingly optimized. The resulting proposed approach is then tested by means of numerical simulations over a base case scenario before renovation. The main conclusion of this work is the demonstration that control strategy of energy generation and distribution systems has to be revised whenever deep renovation of passive or active building technologies is undertaken. Contrarily to which, project renovation goals cannot be met. [less ▲]

Coherent backscattering generally refers to a significant and robust enhancement of the average backscattering probability of a wave within a disordered medium, which from a semiclassical point of view arises due to the constructive interference between backscattered trajectories and their time-reversed counterparts. We recently investigated the manifestation of this wave interference phenomenon in the Fock space of a disordered Bose-Hubbard system of finite extent [1], which can potentially be realized using ultracold bosonic atoms within optical lattices. Preparing the atoms in a well-defined Fock state of the lattice and letting the system evolve for a finite time will, for suitable parameters of the system and upon some disorder average over random on-site energies of the lattice, generally give rise to an equidistribution of the occupation probability within the energy shell of the Fock space that corresponds to the initial energy of the system, in accordance with the quantum microcanonical ensemble. We find, however, that the initial state is twice as often encountered as other Fock states with comparable total energy, which is a consequence of coherent backscattering [1]. Most recently, we showed that this phenomenon also arises in spin 1/2 Fermi-Hubbard rings that involve Rashba hopping terms (which combine inter-site hoppings with spin flips and arise from spin-orbit coupling), for which a newly developed semiclassical theory [2] correctly predicts a coherent enhancement of the occupation probabilities of the initial state and its spin-flipped counterpart. Moreover, performing a global spin flip within this Fermi-Hubbard system will give rise to significant spin echo peaks on those two Fock states, which is again a consequence of quantum many-body interference [3]. The semiclassical predictions of these enhancements and peaks are found to be in very good agreement with numerical findings obtained from the exact quantum time evolution within this Fermi-Hubbard system.

Psoriasis is a chronic, systemic inflammatory disease with skin maniifestations resulting from a dysregulated immune response. Itching is one of the most bothersome psoriasis symptoms for patients and important factor contributing to disease severity. Apremilast , is an oral small-molecule phosphodiesterase 4 (PDE4) inhibitor, works intracellularly within immune cells to regulate the production of inflammatory médiators associated with the pathogenesis of psoriasis by increasing cyclic adenosine monophophate (cAMP) levels. Apremilast was approved by the US Food and Drug Administration for the treatment of adult patients with patients with active psoriatic arthritis and for patients with moderate to severe plaque psoriasis. Apremilast has since been approved in multiple countries, including those in European Union,as well as Switzerland, Canada and Australia. LIBERATE (Evaluation in Placebo-Controlled Study of Oral Apremilast and Etanercept in Plaque Psoriasis; NCT01690299) is global phase 3b study evaluating the efficacity, safety, and tolerability of apremilast or etarnercept, compared with placebo, for the treatment of biologic-naive patients with moderate to severe plaque psoriasis.

In 1964-1974, the German artist Max Ernst created, with the help of two friends, a series of works (books, movie, paintings) related to the astronomer Wilhelm Tempel. Mixing actual texts by Tempel and artistic features, this series pays homage to the astronomer by recalling his life and discoveries. Moreover, the core of the project, the book Maximiliana or the Illegal Practice of Astronomy, actually depicts the way science works, making this artwork a most original tribute to a scientist.

Les services de renseignement qui agissent dans un cadre par nature secret peuvent induire une certaine méfiance chez le citoyen. Dans cette période troublée que nous traversons, le grand public se doit d’être informé sur le fonctionnement des services de renseignement belges et le contrôle de ces derniers. Pierre angulaire du système de contrôle, cet ouvrage cherche à apporter une analyse objective du travail réalisé par Comité R dans sa relation avec les acteurs politiques avant la sixième réforme de l’Etat. Ce livre cherche ainsi, sans prétention, à contribuer au développement de la culture du renseignement en Belgique ou, dans une certaine mesure, à lever le voile sur certains préjugés. [less ▲]

For hyperspectral imaging, diffraction gratings based spectrometers exhibit high spectral resolution and optical performance. Among those spectrometers, the Offner type (which consists of an entrance slit, two concave mirrors and convex grating) offers a lot of advantages. In this paper, we propose the design and modelization of a convex grating which covers a spectral band ranging from 0.7 μm to 5 μm with a minimum diffraction efficiency of 20% at 800 nm, 50% at 3000 nm and 25% at 5000 nm. For a so wide band, a grating with a single blaze cannot satisfy these requirements. We will therefore propose an approach of multi-blaze grating which is subdivided into different sections each with its own blaze angle. Meanwhile, we perform the diffraction efficiency prediction using the scalar and rigorous theories to prove the compliance of this design with the technical specifications. The rigorous theory will also allow us to study the polarization sensitivity of this grating and the calculation of the diffraction efficiency of a grating with a profile degraded by manufacturing errors to assess the impact on the diffraction efficiency and the sensitivity to polarization [less ▲]
