Texto completo da fonteThe world population is increasingly aging; thus, understanding the mechanisms of aging has become a priority for the WHO.The extracellular matrix (ECM) plays a crucial role in aging that is still little known due to its complex 3D architecture and composition, including large proteins such as collagens. The latter are critical components of the integrity, structure, and physicochemical properties of the ECM since they form supramolecular assemblies that contribute to tissue architecture. During aging, the ECM undergoes a remodeling process via various post-translational modifications (PTMs), some contribute to its function, but others can affect its physical and mechanical properties. One of the modifications observed in collagens is carbamoylation: a non-enzymatic PTM, which results from the fixation of isocyanic acid, mainly from the decomposition of urea, on the amino groups of proteins. The binding of isocyanic acid to lysine forms the compound homocitrulline (HCT). Recent experimental studies from our research unit have shown that the accumulation of carbamoylation derivatives such as HCT in the skin could alter collagen properties and be correlated with skin aging.This thesis proposes to study the impact of carbamoylation on type I collagen via in silico approaches with finer dimensional resolution than usual experimental techniques. The proposed strategy is translational and combines results from quantum mechanics, all-atom molecular dynamics (MD), and coarse-grained or even mesoscopic representations. First, since in the AMBER force field (optimized to describe native collagen), there are no parameters available to describe HCT, this MPT was parameterized using quantum mechanics. Then, the use of classical molecular modeling, and more particularly of numerical simulations of MD on collagen sections, allowed us to characterize the dynamic behavior of the carbamoylated triple helix. The specific region was selected based on experimental data from the laboratory, and four different systems containing from zero to three HCTs were studied. The MD trajectories were analyzed to evaluate the impact of the modification(s) on the backbone and the side chain of the triple helix. The presence of one to three HCTs, colocalized in the same region, has little impact on the overall structure of the backbone (the polyproline-II type structure is preserved); on the other hand, a local perturbation of the dynamics of the triple helices is observed. Indeed, the characterization of the dihedral angles of the HCT side chain highlights a change in the behavior of the χ4 torsion compared to the native lysine residue. Furthermore, still at the local level, carbamoylation modifies the nature of the interactions since the salt bridges formed by and between the lysines are replaced by weak hydrogen bond interactions between the HCT side chain and the protein backbone.The results highlight, at the atomic level, the local, and not global, impact of carbamoylation, regardless of the number of modifications considered. However, given the different scales of supramolecular assembly of type I collagen (fibrils then fibers), approaching the study of this system through coarse-grained simulation (grouping of non-polar atoms on a single bead) or even mesoscopic is a study path that seems necessary to integrate synergistic effects along the triple helix, or even the fibril, and that we have begun to explore

Texto completo da fonteThis thesis consists of three contributions related to the Coq formalization of error analysis in numerical analysis and floating-point arithmetic.First, we have exhibited an algorithm computing the average of two decimal floating-point numbers and have proved that this algorithm computes the correct rounding. We have formalized the algorithm and its correctness proof in the Coq proof assistant.The second contribution of the thesis is the analysis and the formalization of rounding error bounds associated to the implementation of Runge-Kutta methods applied to linear systems. We have proposed a generic methodology to build a bound on the error accumulated over the iterations, taking potential underflow and overflow into account. We have then instantiated this methodology forclassic Runge-Kutta methods, e.g. the Euler and RK2 methods. We have proposed a formalization of the results, including the definition of matrix norms, theproof of rounding error bounds for matrix operations and the formalization of the generic results and their instantiations.Finally, we have proposed a formalization of functional analysis results that serve as foundations for the finite element method. This formalization is based on the Coquelicot library and includes the theory of Hilbert spaces, the formal proof of the Lax--Milgram Theorem and the proof of completeness of finite dimensional subspaces of Hilbert spaces

Texto completo da fonteIn the field of rubber material development, CB is the most commonly used reinforcing filler. The characterization of CB morphology and nanostructure is therefore crucial to understand the physicochemical properties induced by the introduction of CB in rubber materials. Classical analytical methods only allow indirect and incomplete access to these properties. This PhD offers an innovative method that allows the automatic identification of CB grades by coupling Scanning Transmission Electron Microscopy (STEM) detector and image processing chain. A thorough statistical investigation over a hundred of morphological and structural characteristics of CB was performed on a set of 6000 STEM images. This study has introduced 7 new features and selected the 37 most discriminating descriptors to create the final model. An unsupervised segmentation algorithm has been developed and evaluated in order to build an automatic process as efficient as possible. Then, five classifiers were trained and compared on a base of nearly 65,000 aggregates. It appears that the most suitable descriptor is the Neuron networks as it gives a perfect recognition. As the recognition model is based on 2D projections of CB aggregates, it is necessary to verify that the chosen descriptors are indeed able to correctly characterize the three dimensional structure of CB. The statistical comparison of the 2D descriptors with 3D descriptors extracted from electronic tomography images has been successful, and therefore demonstrates the relevance of the model. The proposed approach, starting from the sample preparation and STEM acquisitions to their classification and through the image analysis steps, offers a new and innovative method for the reliable characterization of CB. This method can be used routinely on raw CB or CB extracted from vulcanizes rubbers
