The present study tested the hypothesis that contiguity, regarding time of administration of the Tellegen Absorption Scale (TAS), differentially influences hypnotic susceptibility. Forty-eight subjects were administered the TAS immediately prior to assessment of hypnotic susceptibility versus 43 subjects who received the TAS one to three days before assessment of hypnotic susceptibility. Absorption, when measured in the temporally versus nontemporally contiguous context did not appear to affect hypnotic susceptibility. Absorption did, however, correlate significantly with hypnotic susceptibility in the temporally contiguous group as compared to a non-significant correlation in the nontemporally contiguous group. This finding suggests is a relationship between differential administration of the TAS with regard to time of administration and hypnotic susceptibility.

Yes / In this work, an analytical study of the electromagnetic propagation in a complex medium-based suspended three-layer coplanar waveguide (CPW) is carried out. The study aims at a numerical calculation of the dominant hybrid mode complex propagation constant in the CPW printed on a bianisotropic substrate. The herein considered bianisotropy is characterized by full 3×3 tensors of permittivity, permeability and magnetoelectric parameters. The study is based on the numerical derivation of the Green's functions of such a complex medium in the spectral domain. The study is carried out using the Full Generalized Exponential Matrix Technique based on matrix- shaped compact mathematical formulations. The Spectral Method of Moments (SMoM) and the Galerkin's procedure are used to solve the resulting homogeneous system of equations. The effect of the chiral and achiral bianisotropy on the complex propagation constant is particularly investigated. Goo d agreements with available data for an anisotropic-medium-based suspended CPW structure are achieved. Various cases of chiral and achiral bianisotropy have been investigated, and particularly, the effect on the dispersion characteristics is presented and compared with cases of isotropic and bianisotropic Tellegen media. / FCT/MEC through national funds and when applicable co-financed by the ERDF, under the PT2020 Partnership Agreement under the UID/EEA/50008/2019 project.

Yes / In this paper, we present an analytical study for the investigation of the effects of the magnetoelectric elements of a reciprocal and nonreciprocal bianisotropic grounded substrate on the input impedance, resonant length of a dipole antenna as well as on the mutual coupling between two element printed dipole array in three configuration geometries: broadside, collinear and echelon printed on the same material. This study examines also the effect of the considered bianisotropic medium on the electric and magnetic field distributions that has been less addressed in the literature for antenna structures. Computations are based on the numerical resolution, using the spectral method of moments, of the integral equation developed through the mathematical derivation of the appropriate spectral Green’s functions of the studied dipole configuration. Original results, for chiral, achiral, Tellegen and general bi-anisotropic media, are obtained and discussed with the electric and magnetic field distributions for a better understanding and interpretation. These interesting results can serve as a stepping stone for further works to attract more attention to the reciprocal and non-reciprocal Tellgen media in-depth studies.

Le sujet de cette thèse est la conception et l'implantation d'algorithmes efficaces pour des opérations de base en calcul formel, ainsi que leurs applications à des domaines connexes, comme la théorie algorithmique des nombres et la cryptographie. Une première partie traite de l'algorithmique de base sur les polynômes à une variable. L'outil systématiquement mis en oeuvre est une version constructive du principe de transposition de Tellegen, qui permet d'obtenir de nouveaux algorithmes pour l'évaluation multipoint et l'interpolation (dans diverses bases polynomiales et pour diverses familles de points d'évaluation), ainsi qu'un théorème d'équivalence entre les complexités de ces deux problèmes. La deuxième partie est consacrée à l'algorithmique des nombres algébriques. Nous étudions d'abord certaines opérations élémentaires, comme la somme, le produit et leur généralisation, le produit diamant de Brawley et Carlitz. Leur calcul repose sur l'utilisation de l'opérateur de Newton formel et de la dualité algébrique, traduite algorithmiquement par l'emploi du principe de transposition et des méthodes de type pas de bébés / pas de géants. Ces méthodes sont ensuite généralisées au cadre des systèmes de polynômes de dimension zéro, pour le calcul de polynômes minimaux dans des algèbres quotient, ainsi que de paramétrisations rationnelles. Dans la troisième partie, nous étudions la question du calcul d'un terme d'une suite récurrente linéaire à coefficients polynomiaux. Comme application, nous obtenons des améliorations théoriques et pratiques des méthodes de comptage de points utilisées en cryptographie. Nous proposons ensuite une méthode de type évaluation-interpolation pour certaines opérations usuelles sur les opérateurs différentiels linéaires à coefficients polynomiaux.
