In this paper, we present an original concept of plasmonic-related instrumentation platform dedicated to diagnostic biosensing tests out of the laboratory. The developed instrumental platform includes both disposable one-use microfluidic affinity biochip and compact optical readout device for biochip monitoring involving mobile Internet devices for data processing and communication. The biochip includes both microfluidic and optical coupling structures formed into a single plastic slab. The microfluidic path of the biochip operates in passive capillary pumping mode. In the proof-of-concept prototype, we address specifically the sensing format involving Surface Plasmon Resonance phenomenon. The biochip is plugged in the readout device without the use of an index matching fluid. An essential advantage of the developed biochip is that its implementation involves conventional hot embossing and thin film deposition process, perfectly suited for mass production of low-cost microfluidic biochip for biochemical applications.

In this paper, we present an original method of dot-pattern generation dedicated to design optimization of large-size format ELBUs (Edge-Lit Light Guide Unit), where the number of dots greatly exceeds the maximum allowable number of optical objects supported by most common ray-tracing software. In the proposed method, in order to simplify the computational problem, an original optical system is replaced by an equivalent one. Accordingly, the original dot pattern is splitted into multiple small sections. Then, these sections are replaced by equivalent cells with continuous diffusing film. After that, we adjust the TIS (Total Integrated Scatter) two-dimensional distribution over the grid of equivalent cells, using an iterative optimization procedure. Finally, the obtained optimal TIS distribution is converted into the dot size distribution by applying an appropriate conversion rule. An original semi-empirical equation dedicated to rectangular large-size LGPs (Light Guide Plate) is proposed for the initial guess of the TIS distribution. It allows significantly reducing the time needed to dot pattern optimization. [less ▲]

Recently, evidence has been presented for the polarization vectors from quasars to preferentially align with the axes of the large quasar groups (LQG) to which they belong. This report was based on observations made at optical wavelengths for two large quasar groups at redshift ~1.3. The correlation suggests that the spin axes of quasars preferentially align with their surrounding large-scale structure that is assumed to be traced by the LQGs. Here, we consider a large sample of LQGs built from the Sloan Digital Sky Survey DR7 quasar catalogue in the redshift range 1.0 -􀀀 1.8. For quasars embedded in this sample, we collected radio polarization measurements with the goal to study possible correlations between quasar polarization vectors and the major axis of their host LQGs. Assuming the radio polarization vector is perpendicular to the quasar spin axis, we found that the quasar spin axis is preferentially parallel to the LQG major axis inside LQGs that have at least 20 members. This result independently supports the observations at optical wavelengths. We additionally found that when the richness of an LQG decreases, the quasar spin axis becomes preferentially perpendicular to the LQG major axis and that no correlation is detected for quasar groups with fewer than 10 members.

Through this contribution I make use of a Transnational Situated feminist objective lens (Haraway, 1988 , Fernandes, 2013 , Kaplan, 1994 ) to depict the impact of my geopolitical-locations and multi-layered transnational identities on my choice of research topic, project design and definition of research object (Koobak and Thapar-Bjorkert, 2014) . In order to do so, I draw from examples of my multi-sited fieldwork with migrant domestic workers in Brussels and their family members in Peru and Colombia. Through the analysis, I first show how the use of such methodological tool during my pilot fieldwork shifted the aim of my research and led me to focus on the global inequalities experienced by ageing migrant domestic workers in the area of social protection. Secondly, I explore how the same methodological tool led me to choose the adequate intersectional theoretical perspectives and methods to properly address my research object. Thirdly, I show how these same reflections led me to plan ethical measures to produce knowledge under less asymmetrical power relations. This paper shows that my geopolitical locations and multi-layered transnational identities not only enlighten my everyday life experience but also impact the ways in which I construct and conduct my research. Moreover, it highlights the importance of acknowledging the multi-layered nature of the locations from which we write in order to hold ourselves accountable for the situated knowledge we produce. Lastly, this paper shows that reflections on the politics of locations can be useful both for minoritized subjects such as myself who challenge the hegemonic archetypes from the edges as well as for others who occupy more advantageous positions.

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.

Plant-based biopharmaceuticals have gained a lot of interest in the past decade due to their reduced cost and relative safety compared to mammalian cell cultures. While the first plant-made recombinant proteins are now reaching the market, the production systems still need improvements to maximize their competitiveness. Optimizing production hosts requires the identification and subsequent inhibition of the most active endogenous peptidases, proteolysis being one of the main factors limiting yields. The aim of our study was to identify root-secreted proteases of Arabidopsis thaliana involved in target protein degradation (BSA) and inhibit them in vivo. Biochemical analyses identified serine proteases as the main class responsible for BSA degradation. An RT-qPCR experiment led to the choice of the serine protease gene SBT4.12 and its homologs as targets for an amiRNA-mediated silencing approach. Arabidopsis amiRNA-expressing lines showed lower levels of expression for SBT4.12 and reduced proteolytic activity in their rhizosecreted extracts. Crossing these lines with recombinant protein producing lines could lead to an improved production platform for proteins of interest. [less ▲]

This chapter falls within the context of the optimization of the levelized energy cost (LEC) of microgrids featuring photovoltaic panels (PV) associated with both long-term (hydrogen) and short-term (batteries) storage devices. First, we propose a novel formalization of the problem of building and operating microgrids interacting with their surrounding environment. Then we show how to optimally operate a microgrid using linear programming techniques in the context where the consumption and the production are known. It appears that this optimization technique can also be used to address the problem of optimal sizing of the microgrid, for which we propose a robust approach. These contributions are illustrated in two different settings corresponding to Belgian and Spanish data. [less ▲]

PURPOSE: To experimentally compare the optical performance of three types of hydrophobic intraocular lenses (IOLs): extended depth of focus, bifocal, and trifocal. METHODS: The tested IOLs were: TECNIS ZMB00 (bifocal; Abbott Medical Optics, Abbott Park, IL), TECNIS Symfony ZXR00 (extended depth of focus; Abbott Medical Optics), and FineVision GFree hydrophobic (trifocal; PhysIOL, Liège, Belgium). Their surface topography was analyzed by optical microscopy. Modulation transfer function (MTF) and spherical aberrations were determined on optical bench for variable pupil apertures and with two cornea models (0 μm and +0.28 μm). United States Air Force target imaging was analyzed for different focal points (near, intermediate, and far). Point spread function (PSF) and halos were quantified and compared. RESULTS: The three lenses presented step-like optic topography. For a pupil size of 3 mm or greater, clearly distinctive MTF peaks were observed for all lenses: two peaks for the extended depth of focus and bifocal lenses with +1.75 and +4.00 diopters (D) addition, respectively, and three peaks for the trifocal lens with +1.75 and +3.50 addition for intermediate and near vision, respectively. The extended depth of focus and bifocal lens had slightly higher MTF at best focus with the +0.28 μm cornea model than with the 0 μm model, whereas the trifocal lens was likely to be more independent of the corneal spherical aberrations.CONCLUSIONS: It appears that the three lenses rely on light diffraction for their optical performance, presenting halos with comparable intensities. For small pupil apertures (< 3 mm), the MTF peaks for the far and intermediate focal distances of the trifocal and extended depth of focus lenses overlap, but the trifocal lens presented an additional MTF peak for the near focal points.
