This paper challenges the effectiveness and necessity of “mass surveillance technology”(MST) on two dimensions: (a) states’ internal use of MST and the subsequent issue of violation of fundamental freedoms, and (b) surveillance technology export control, especially to third countries likely to use such technology to violate human rights. Following the Snowden Datagate scandal, many States undertook inquiries and adopted measures that, in some cases, were meant to regulate the use of mass surveillance technology. The paper will: a) assess and evaluate current regulations on mass surveillance technology and its place in democratic societies, including what is at stake in terms of technology, threats, reactions to threats, and geographic extension, b) the risks linked to the use of MST on the national level by questioning the validity of counter-terrorism measures as a justification for MST use c) analyze international trade control regimes and legislation to highlighting their inadequacy in the face of the threats posed by MST, and d) map the evolution of the EU dual-use trade control system towards a human security approach with regard to human rights protection, in order to assess the capability of the system to avoid the misuse of MST.

The study of the durability of cementitious materials like mortar which are the object of massive use in building and engineering works implies a perfect understanding of their mass transfer properties. This work reports the results of experimental study concerning the influence of water-to cement ratios used for the preparation of the material on its convective drying kinetics. Three tips of mortar were realized and studied with three different water to cement (W/C) ratios; W/C =0.4, W/C = 0.5 and Mortar with ratio W/C = 0.6. The first experimental campaign was done in a convective dryer, using cubic samples of mortar of size (15 X 15 X 10) mm3. The sample was continuously weighed during the drying test and its mass was recorded every 2 minutes in order to obtain the drying curves. These tests present the advantage of reproducing the natural conditions met in the problems of atmosphere-material interactions. A second experimental campaign aimed to characterize from both a textural and hydric point of views, the materials, by mean of DVS (dynamic vapour sorption). The mass diffusivity coefficient and the pore size distribution of mortar were obtained from adsorption-desorption cycles. On the other hand the influence of the air drying humidity during the convective drying in the conditions of velocity, temperature and debit of air checked by the convective dryer was studied. From these campaigns, it was observed that the increase of the ratio W/C engenders an increase of the drying kinetics due to the increase of the initial porosity [less ▲]

Texture and morphology of a Pd-Ag/SiO2 hydrodechlorination low-density xerogel catalyst prepared by a cogelation sot-gel process were characterized in detail to examine mass transfer in such catalysts. The catalyst consists of active Pd-Ag nanocrystallites trapped inside elementary 20 nm microporous silica particles arranged in larger aggregates, which constitute the macroscopic pellet. To reach active sites, reactants must first diffuse through large pores located between aggregates of SiO2 Particles and then through smaller pores located between those elementary particles inside the aggregates. Finally, they, diffuse through micropores located inside silica particles. Diffusion in such a "funnel" structure cannot be described assimilating the pellet to a pseudo-continuum. Diffusion should be examined carefully at three levels of decreasing size: the macroscopic pellet, the aggregate of silica particles, and the elementary silica particle. This approach shows that cogelled xerogel catalysts have remarkable mass-transfer properties. [less ▲]

The light travel time differences in strong gravitational lensing systems allows an independent determination of the Hubble constant. This method has been successfully applied to several lens systems. The formally most precise measurements are, however, in tension with the recent determination of H[SUB]0[/SUB] from the Planck satellite for a spatially flat six-parameters ΛCDM cosmology. We reconsider the uncertainties of the method, concerning the mass profile of the lens galaxies, and show that the formal precision relies on the assumption that the mass profile is a perfect power law. Simple analytical arguments and numerical experiments reveal that mass-sheet like transformations yield significant freedom in choosing the mass profile, even when exquisite Einstein rings are observed. Furthermore, the characterization of the environment of the lens does not break that degeneracy which is not physically linked to extrinsic convergence. We present an illustrative example where the multiple imaging properties of a composite (baryons + dark matter) lens can be extremely well reproduced by a power-law model having the same velocity dispersion, but with predictions for the Hubble constant that deviate by ~20%. Hence we conclude that the impact of degeneracies between parametrized models have been underestimated in current H[SUB]0[/SUB] measurements from lensing, and need to be carefully reconsidered.

G-protein-coupled receptors (GPCRs) constitute the largest family of transmembrane proteins. Although implicated in almost all physiological processes in the human body, most of them remain unexploited, mostly because of the lack of specific ligands. The objective of this work is to develop a new mass-spectrometry-based technique capable of identifying new peptide ligands for GPCRs. The strategy is based on the incubation of cellular membranes overexpressing GPCRs with a mixture of peptides that contains potential ligands. Peptide ligands bind to the receptors, whereas other peptides remain in the binding buffer. Bound peptides are eluted from membranes and directly detected, identified, and characterized by MALDI TOF–TOF. The results reveal the efficacy of the procedure for selecting a specific ligand of GPCRs in both simple and complex mixtures of peptides. This new approach may offer direct purification, identification, and characterization of the new ligand in a single workflow. The proposed method is labeling-free and, unlike radio-binding and other techniques, it does not require a previously known labeled ligand of the studied GPCR. All these properties greatly reduce the experimental constraints. Moreover, because it is not based on the principle of a competitive specific binding, this technique constitutes a new tool to discover new ligands not only for known GPCRs, but also for orphan GPCRs [less ▲]

La Renaissance prend des accents inattendus avec Pierre Bruegel l’Ancien. A contre-courant des goûts antiquisants et italianisants, l’artiste exalta les traditions spécifiques de son pays natal et réalisa ainsi des œuvres originales, parfois déroutantes. Tandis que les Pays-Bas espagnols s’enfonçaient dans la guerre civile, Bruegel peignit une version insolite du Massacre des innocents, où il situait l’épisode biblique dans un village flamand et le traitait comme une scène d’actualité. Si ce chef-d’œuvre nous est parvenu fort altéré suite à des restaurations anciennes, nous pouvons en restituer l’apparence initiale grâce aux copies très fidèles qu’en réalisa plus tard le fils aîné de Bruegel, Pierre dit le Jeune. Nous découvrons ainsi toute l’audace dont fit preuve un artiste en vue, prisé dans les hautes sphères du pouvoir, jouant sur l’ambiguïté et le double sens pour exposer des positions subversives dans un contexte de répression politique sans merci.
