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…

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…

Contrastive learning: an efficient Domain Adaptation strategy for 2D mammography image classification

Effective computer aided breast-cancer diagnosis models using 2D mammography images must maintain consistent performance across varying image acquisition systems and post-processing techniques. Nevertheless, Deep Learning (DL) models have shown…

On the local geometry of the pet reconstruction problem

Intrinsic uncertainties related to the ill-posedness of the PET image reconstruction inverse problem are investigated in this work. These uncertainties could lead to instabilities in the reconstructed images in particular when Deep Learning…

Symbolic representations of time series

The objectives of this thesis are to define novel symbolic representations and distance measures that are suited for time series that can be multivariate and non-stationary. In addition, they should preserve the time information, be interpretable,…

Virial Theorem and Its Applications in Instability of Two-Phase Water-Wave

In this paper, we analyze the dynamics of two layers of immiscible, inviscid, incompressible, and irrotational fluids through a full nonlinear system. Our goal is to establish a virial theorem and prove the polynomial growth of slope and curvature…

Weill-Marchesani syndrome: natural history and genotype-phenotype correlations from 18 news cases and review of literature

Background Weill-Marchesani syndrome (WMS) belongs to the group of acromelic dysplasias, defined by short stature, brachydactyly and joint limitations. WMS is characterised by specific ophthalmological abnormalities, although cardiovascular defects…

Vitamin K Epoxide Reductase Complex–Protein Disulphide Isomerase Assemblies in the Thiol–Disulphide Exchange Reactions: Portrayal of Precursor-to-Successor Complexes

The human Vitamin K Epoxide Reductase Complex (hVKORC1), a key enzyme that converts vitamin K into the form necessary for blood clotting, requires for its activation the reducing equivalents supplied by its redox partner through thiol–disulphide…
