Abstract

A metasurface consisting of a 2D periodic square lattice of metallic square ring resonators is considered for supporting spoof surface plasmon polariton (SSPP) modes. First, SSPP modes are highlighted by simulated dispersion curves. The dispersion curves are analyzed by considering hybridization of modes in either a patch or an aperture array with frequency shifts. Hybridization of modes is also supported by means of surface current and electric field mappings showing consistent symmetric and anti-symmetric fields. Second, it is shown that a dipole antenna located near the metasurface is able to generate SSPP modes. The transmission spectra between two antennas located at each extremity of the metasurface show transmission enhancements compared with propagation in free space. The transmission enhancements are shown for different locations of the antennas either facing each other or positioned in diagonal. Finally, the transmission enhancement is connected to SSPP modes by comparing the transmission spectra and the measured dispersion curves with each other. Specifically, two transmission windows measured for an embroidered metasurface are related to the cutoff frequency of the two SSPP modes supported by the metasurface as evidenced by the measured dispersion curves.

Abstract

The theoretical performance and some results from the clinical investigation of a new low-vision aid system are analyzed. This device is composed of a spectacle lens and an intraocular lens. The aberrations of this system have been computed and then reduced by optimal aspherization of the optical surfaces. A specialized sophisticated system for controlling the aspheric surfaces is described briefly. Finally the results of the clinical investigation are presented. Key words: Aspherics, intraocular lens, low-vision aid system.

Abstract

International audience; The biological processes associated with the onset of schizophrenia remain largely unknown. Current hypotheses favor gene x environment interactions as supported by our recent report about DNA methylation changes during the onset of psychosis. Here, we conducted the first longitudinal transcriptomic analysis of blood samples from 31 at-risk individuals who later converted to psychosis and 63 at-risk individuals who did not. Individuals were followed for a maximum of 1 year. Blood samples were collected at baseline and at the end of follow-up and individuals served as their own controls. Differentially expressed genes between the 2 groups were identified using the RNA sequencing of an initial discovery subgroup (n = 15 individuals). The most promising results were replicated using high-throughput real-time qPCR in the whole cohort (n = 94 individuals). We identified longitudinal changes in 4 brain-expressed genes based on RNAseq analysis. One of these genes (CPT1A) was replicated in the whole cohort. The previously observed hypermethylation in NRP1 and GSTM5 during the onset of psychosis correlated with a decrease in corresponding gene expression. RNA sequencing also identified 2 co-expression networks that were impaired after conversion compared with baseline-the Wnt pathway including AKT1, CPT1A and semaphorins, and the Toll-like receptor pathway, related to innate immunity. This longitudinal study of transcriptomic changes in individuals with at-risk mental state revealed alterations during conversion to psychosis in pathways and genes relevant to schizophrenia. These results may be a first step toward better understanding psychosis onset. They may also help to identify new biomarkers and targets for disease-modifying therapeutic strategies.

27. Diffusion of foreign euro coins in France, 2002-2012

Abstract

Since they were brought into circulation in 2002, euro coins have travelled widely across Europe. The country of issue gives an indirect indication of the movements of the individuals who have carried these coins and of the intensity of international relations. The percentage of foreign euro coins in France rose from 5% in March 2002 to 34% inDecember 2011, and the proportion is greater for coins with a higher face value (50 cents, 1 or 2 euro), which are more mobile. Distance from the national border is a key factor explaining the domination of Spanish coins in the south-west and of German and Belgian coins in the north-east. Alongside crossborder movements, travel between cities for work purposes and movements of tourists also contribute to the mixing process, as shown by the more diffuse spread of Italian coins across France.
