The graded group action framework for sub-riemannian orbit models in shape spaces

In the standard orbit model on shape analysis, a group of diffeomorphism on the ambient space equipped with a right invariant sub-riemannian metric acts on a space of shapes and induces a sub-riemannian structure on various spaces. An important…

Méthodologie de calcul des lois de survie à partir de tests de fatigue

Dans ce papier, nous explorons une méthodologie permettant d’établir des trajectoires de vieillissement à partir d’essai de fatigue. Notre approche s’appuie sur des chaînes de Markov et permet de proposer une méthode pour calculer des lois de survie…

Corrélats cérébraux de l’anxiété catégorielle et dimensionnelle

Anxiety disorders are highly prevalent and represent a heavy burden of disease. However, despite a large group-level neuroimaging literature, robust brain markers of vulnerability or therapeutic response struggle to emerge. In recent years,…

CNS erythroblastic sarcoma: a potential emerging pediatric tumor type characterized by NFIA::RUNX1T1/3 fusions

Abstract Erythroblastic sarcoma (ES) (previously called chloroma or granulocytic sarcoma) are rare hematological neoplams characterized by the proliferation of myeloid blasts at extramedullary sites, and primarily involve the skin and soft tissue of…

Convergence to line and surface energies in nematic liquid crystal colloids with external magnetic field

We use the Landau-de Gennes energy to describe a particle immersed into nematic liquid crystals with a constant applied magnetic field. We derive a limit energy in a regime where both line and point defects are present, showing quantitatively that…

d_symb playground: an interactive tool to explore large multivariate time series datasets

Exploring and comparing non-stationary multivariate time series is an important problem in many domains and real-world applications. In recent work, we introduced d_symb, a symbolic representation that transforms multivariate time series into…

Visualising the self-assembly dynamics of icosahedral viruses through fluorescence microscopy at the single-particle level

All viruses on Earth use the machinery of host cells to replicate themselves. Therefore, there is a lot of ongoing work to understand the dynamics of the self-assembly process that forms viral capsids from proteins and nucleic acids. Recent research…

Cross-modality mapping using image varifolds to align tissue-scale atlases to molecular-scale measures with application to 2D brain sections

This paper explicates a solution to building correspondences between molecular-scale transcriptomics and tissue-scale atlases. This problem arises in atlas construction and cross-specimen/technology alignment where specimens per emerging technology…

Data enabled Predictive Control of LPV systems

This paper introduces a data-enabled predictive control methodology designed for Linear Parameter Varying (LPV) systems. By leveraging a polytopic representation of the LPV system, we formulate Willem’s lemma to accommodate parameter variations. The…
