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 ...

An Étude on the regularization and renormalization of divergences in primordial observables
AbstractMany cosmological observables derive from primordial vacuum fluctuations evolved to late times. These observables represent statistical draws from some underlying quantum or statistical field theoretic framework where infinities arise and require regularization.

Regularization and Renormalization of Chern-Simons Theory [PDF]
We analyze some features of the perturbative quantization of Chern-Simons theory (CST) in the Landau gauge. In this gauge the theory is known to be perturbatively finite. We consider the renormalization scheme in which the renormalized parameter $k$ equals the bare or classical one and show that it constitutes a natural parametrization for the quantum ...

Ringdown Modulation of Acceleration Radiation in the Schwarzschild Background
ABSTRACT We derive an analytic first‐order description of how Schwarzschild ringdown affects a detector‐based detailed‐balance diagnostic in a near‐horizon, single‐mode setting. A freely falling two‐level system couples to a cavity‐filtered outgoing mode of fixed asymptotic frequency, whose static Schwarzschild response gives geometric photon ...

Regularization, renormalization, and dimensional analysis: Dimensional regularization meets Freshman E&M [PDF]
We illustrate the dimensional regularization technique using a simple problem from elementary electrostatics. We contrast this approach with the cutoff regularization approach, and demonstrate that dimensional regularization preserves the translational ...

Regularization Scheme Dependence of the Counterterms in the Galaxy Bias Expansion [PDF]
In this paper we explore how different regularization prescriptions affect the counterterms in the renormalization of the galaxy bias expansion. We work in the context of primordial local non-Gaussianity including non-linear gravitational evolution.

From operator product expansion to anomalous dimensions
We propose a new method for computing the renormalization functions, which is based on the ideas of operator product expansion and large momentum expansion.

Running couplings from adiabatic regularization
We extend the adiabatic regularization method by introducing an arbitrary mass scale μ in the construction of the subtraction terms. This allows us to obtain, in a very robust way, the running of the coupling constants by demanding μ-invariance of the ...

Non-perturbative renormalization of left-left four-fermion operators in quenched lattice QCD [PDF]
We define a family of Schroedinger Functional renormalization schemes for the four-quark multiplicatively renormalizable operators of the $\Delta F = 1$ and $\Delta F = 2$ effective weak Hamiltonians. Using the lattice regularization with quenched Wilson
