Medicine Advances, EarlyView.We developed the Glioma Multiparametric MRI Analysis System (GMMAS), a fully automated platform that leverages multi‐task semi‐supervised learning to diagnose gliomas from multiparametric MRI images. It provides accurate tumor segmentation, subtyping, and prognostic predictions, offering a user‐friendly tool for clinicians to enhance diagnosis and ...

The renormalization group equations revisited
, 2018 International audienceStarting from a well-defined local Lagrangian, we analyze the renormalization group equations in terms of the two different arbitrary scales associated with the regularization procedure and with the physical renormalization of the ...

A note on defect stability in d = 4 − ε
Journal of High Energy PhysicsWe explore the space of scalar line, surface and interface defect field theories in d = 4 − ε by examining their stability properties under generic deformations.

Renormalisation of SMEFT bosonic interactions up to dimension eight by LNV operators
Journal of High Energy Physics, 2023 We present the renormalisation group running of the bosonic operators of the Standard Model effective field theory (SMEFT) by the Lepton Number Violating operators (LNVs) at 1-loop order up to O $$ \mathcal{O} $$ (v 4 /Λ4), with v ∼ 246 GeV as the ...

BIDUAL OCTAHEDRAL RENORMINGS AND STRONG REGULARITY IN BANACH SPACES [PDF]
Journal of the Institute of Mathematics of Jussieu, 2019 AbstractWe prove that every separable Banach space containing an isomorphic copy of $\ell _{1}$ can be equivalently renormed so that the new bidual norm is octahedral. This answers, in the separable case, a question in Godefroy [Metric characterization of first Baire class linear forms and octahedral norms, Studia Math.95 (1989), 1–15].

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Gradient flows and the curvature of theory space
Journal of High Energy PhysicsThe metric and potential associated with the gradient property of renormalisation group flow in multiscalar models in d = 4 − ε dimensions are studied. The metric is identified with the Zamolodchikov metric of nearly marginal operators on the sphere.
