Full textThe first part of the thesis was the study of bright BODIPY nanoparticles (NPFs) (more than 5000 encapsulated molecules). Non-fluorescent aggregates and excimers (lifetime of 1.8 ns) were characterized by time resolved fluorescence experiments. In addition time-resolved fluorescence anisotropy and femtosecond transient absorption spectroscopy experiments revealed efficient ultrafast energy transfer, intermolecular migration (< 25 ps) and singlet-singlet annihilation (< 2 ps). Single particle spectroscopy on NPFs, function of the number of excited molecules within a NPF, revealed some blinking at the scale of about a hundred of milliseconds. However, due to too high density of emissive molecules, complete extinction of fluorescence (OFF state) could not be observed. The absence of OFF state forbid the use of a single molecule localization methods, the second part of this work was thus focused on the development of a data treatment method for single molecule fluorescence images containing high density of emitters. This method (MAPPIX, MAPping Pixel dissimilarity) uses the intensity fluctuations of the probes fluorescence emission over time and is based on a dissimilarity calculation. The results obtained on simulated data and real images were very conclusive. Although it was not possible to be rationalized it in terms of resolution, a contrast improvement bypassing the diffraction limit was observed

Full textFluorescence and Single Molecule Localization Microscopy (SMLM) allows for thespecific labeling and imaging of biological samples, and are an essential tool for biologists.However, images are generally non-quantitative and limited in feld of view, as well as in imagingtimes. These limits are fundamentally linked to the illumination scheme, which should be optimized both in term of uniformity, but also in control of the irradiance. We propose a novelillumination scheme named ASTER, which allow for a versatile and uniform illumination and is compatible with classical optical sectioning schemes. We first apply ASTER to fluorescence microscopy and particularly the imaging of live dynamic samples. Then we show the ability toobtain uniform resolution in SMLM, as well as the potential of ASTER's versatility. One mayreduce the uorescent background, image wide200 x 200 µm² fields, or realize a SMLM image under a minute. Finally, we present theimplementation of a multicolor SMLM experiment, allowing for the simultaneous imaging ofdifferent structures with cross-talks around 2%.This method is quanti ed and optimized, andthen applied to two and three color imaging, aswell as 3D imaging. Different perspectives for ASTER and multicolor imaging are then proposed

Full textSuper resolution microscopy techniques are a useful tool to understand some biomolecular mechanisms, particularly in neurons. We have built such a STED (STimulated Emission Depletion) microscope for observing Nitrogen-Vacancy (NV) fluorescent defect in diamond, and have reached a resolution of 50 nm. In the longer term, this instrument will study the macromolecular organization of proteins involved in synaptic plasticity and marked with fluorescent nanodiamonds (ND). In this context, we studied the resolution limit of STED for ND of subwavelength size. Our experiments, conducted with the team of Stefan Hell (Max Planck Institute for Biophysical Chemistry) showed that the STED spot size of an NV in ND could reach 10 nm, which is similar to performances obtained in a macroscopic diamond. We can also resolve several NV centers, which are separated from only ~15 nm in the same ND. These results are in agreement with numerical simulations carried out by the team of Jean-Jacques Greffet (Laboratoire Charles Fabry). In parallel, we have demonstrated the spontaneous internalization of fluorescent ND in primary culture of cortical neurons from mouse embryos, and studied their colocalization with vesicles of the trans-Golgi network. Finally, we started the study of trafficking vesicles containing ND and showed that it depends on the microtubule network. The motion parameters are compatible with those of molecular motors, but we expect them to be different in the case of overexpression of proteins involved in traffic (work in progress)

Full textThis thesis is devoted to the study of the quantum affine superalgebra associated with the general linear Lie superalgebra and of its representations (finite-dimensional or infinite-dimensional). We establish a trianguler decomposition and a Poincaré-Birkhoff-Witt type theorem for this superalgebra. We propose a definition of Weyl modules in the spirit of Chari-Pressley, and we show that they are always finite-dimensional and non-zero. As a consequence, we obtain a highest weight classification of finite-dimensional simple representations. Our next step is to study in detail the tensor product structure of simple representations. We use the RTT realization of this quantum affine superalgebra, due to Faddeev-Reshetikhin-Takhtajan, to establish a cyclicity result on certain tensor products of Kirillov-Reshetikhin modules. Following Hernandez-Jimbo, we apply the cyclicity result of the second step to construct inductive systems of Kirillov-Reshetikhin modules. We realize their inductive limits as modules over the upper Borel subalgebra, extending the asymptotic construction of Hernandez-Jimbo to the super case. Then we propose a new asymptotic construction to a module structure over the full quantum affine superalgebra on the inductive limits of the same inductive systems

Full textThis thesis is at the crossroads of enumerative, algebraic and bijective combinatorics. It studies some algebraic problems from a combinatorial point of view, and conversely, uses algebraic formalism to deal with combinatorial questions.After a reminder about classical notions of combinatoics and algebraic structures, We introduce new combinatorial objects called the shifted domino tableaux, these objects can be seen as a shifted analog of domino tableaux or as an extension of shifted Young tableaux. We prove that these objects are in bijection with pairs of shifted Young tableaux. This bijection shows that shifted domino tableaux can be seen as elements of the super shifted plactic monoid, which is the shifted analog of the super plactic monoid. We also show that the sum over all shifted domino tableaux of a fixed shape describe a product of two P-Schur functions, and by taking a different kind of shifted domino tableaux we describe a product of two Q-Schur functions. We also propose two insertion algorithms for shifted domino tablaux, analogous to Haiman's left-right and mixed insertion algorithms. Still in the field of bijective combinatorics, we are interested in the second part of our work with bijections related to statistics on permutations and Eulerian numbers.In this second part of this thesis, we introduce the unimodality of finite sequences associated to different directions in the Eulerian triangle. We first give a combinatorial interpretations as well as recurrence relations of sequences associated with the direction (1, t) in the Eulerian triangle, where t≥1. These sequences are the coefficients of polynomials called the t-successive eulerian polynomials, which generalize the eulerian polynomials. We prove using a bijection between premutations and north-east lattice paths that those sequences are unomodal. Then we prove that the sequences associated with the directions (r, q), where r is a positive integer and q is an integer such that r + q ≥ 0, are also log-concave and therefore unimodal

Full textéquationnelle a priori arbitraire. L'agrégation est utilisée pour collecter les différents résultats possibles.
Dans cette thèse, nous étudions différentes combinaisons des ingrédients fondamentaux du rho-calcul: le filtrage, l'agrégation et les mécanismes d'ordre supérieur.
Nous étudions le filtrage d'ordre supérieur dans le lambda-calcul pur modulo une restriction de la beta-conversion appelée super-développements. Cette nouvelle approche est suffisamment expressive pour traiter les problèmes de filtrage du second-ordre et ceux avec des motifs d'ordre supérieur à la Miller.
Nous examinons ensuite les modèles catégoriques du
lambda-calcul parallèle qui peut être vu comme un enrichissement du lambda-calcul avec l'agrégation de termes. Nous montrons que ceci est une étape significative vers la sémantique dénotationnelle du calcul de réécriture.
Nous proposons également une étude et une comparaison des calculs avec motifs éventuellement dynamiques, c'est-à-dire qui peuvent être instanciés et réduits. Nous montrons que cette étude, et plus particulièrement la preuve de confluence, est suffisamment générale pour
s'appliquer à l'ensemble des calculs connus. Nous étudions ensuite l'implémentation de tels calculs en proposant un calcul de réécriture avec filtrage et substitutions explicites.
