Quantum fluctuations induce collective multi-phonons in finite Fermi liquids

We show that collective multi-phonon states in atomic nuclei emerge at high excitation energies when quantum fluctuations are included beyond the independent particle approximation. The quadrupole response of a nucleus is studied using an extension…

Massively parallel computation of globally optimal shortest paths with curvature penalization

We address the computation of paths globally minimizing an energy involving their curvature, with given endpoints and tangents at these endpoints, according to models known as the Reeds-Shepp car (reversible or forward only), the Euler-Mumford…

Temporo-basal sulcal connections: a manual annotation protocol and an investigation of sexual dimorphism and heritability

The temporo-basal region of the human brain is composed of the collateral, the occipitotemporal, and the rhinal sulci. We manually rated (using a novel protocol) the connections between rhinal/collateral (RS-CS), collateral/occipito-temporal (CS-OTS…

Interpretable automatic detection of incomplete hippocampal inversions using anatomical criteria

Incomplete Hippocampal Inversion (IHI) is an atypical anatomical pattern of the hippocampus that has been associated with several brain disorders (epilepsy, schizophrenia). IHI can be visually detected on coronal T1 weighted MRI images. IHI can be…

Barycentric embeddings for geometric manifold learning

An MRI image has over 60,000 pixels. The largest known human protein consists of around 30,000 amino acids. We call such data high-dimensional. In practice, most high-dimensional data is high-dimensional only artificially. For example, of all the…

RADIO-AIDE : une modélisation spatio-temporelle des effets secondaires cognitifs observés dans les suites de la radiothérapie cérébrale

Introduction et but de l’étude La radiothérapie est un traitement majeur des tumeurs du système nerveux central. L’altération des fonctions cognitives, fréquemment observée dans les suites d’une radiothérapie cérébrale, peut être en rapport avec la…

An in-depth study of the deep learning pipeline

Despite the tremendous success of neural networks in many applications, progress in understanding their performance and limits is slow. While universal approximation theorems bring the promise of machines capable of approximating any complex mapping…

Functional inequalities and strong Lyapunov functionals for free surface flows in fluid dynamics

This paper is motivated by the study of Lyapunov functionals for four equations describing free surface flows in fluid dynamics: the Hele-Shaw and Mullins-Sekerka equations together with their lubrication approximations, the Boussinesq and thin-film…
