Sulla Regolarità delle soluzioni di viscosità dell'equazione iconale

Bruno Pini Mathematical Analysis Seminar, 2010
We study the regularity of a viscosity solution of equations of eikonal type in two dierent framework: we consider either the non-degenerate eikonal equation under low regularity assumptions on the data or a possibly degenerate eikonal equation with data

A Review on Explainable, Federated Multimodal AI for Heart Disease Detection Using ECG, Cardiac Imaging, and Electronic Health Records

Engineering Reports, Volume 8, Issue 4, April 2026.
Heart disease remains one of the most critical health challenges globally, accounting for a substantial number of deaths each year. With ML, DL, and FL coming into existence, early diagnosis of heart disease through ECG, Cardiac Imaging, and EHRs became increasingly feasible.

Classical eikonal from Magnus expansion

Journal of High Energy Physics
In a classical scattering problem, the classical eikonal is defined as the generator of the canonical transformation that maps in-states to out-states. It can be regarded as the classical limit of the log of the quantum S-matrix. In a classical analog of

Planckian Scattering Beyond the Eikonal Approximation in the Functional Approach

, 2002
In the framework of functional integration the non-leading terms to leading eikonal behavior of the Planckian-energy scattering amplitude are calculated by the straight-line path approximation.

Landslide Activity in the European Alps ‐ Part 1: A Machine Learning Based Instrumental Catalog From the Analysis of Seismological Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides in the European Alps are a growing concern in the context of climate change. However, landslide catalogs for the European Alps remain incomplete, often lacking precise timing and containing few, if any, entries for remote areas.

Tracking Black Holes in Numerical Relativity

, 2003
This work addresses and solves the problem of generically tracking black hole event horizons in computational simulation of black hole interactions. Solutions of the hyperbolic eikonal equation, solved on a curved spacetime manifold containing black hole

Three‐Dimensional Crustal Deformation Analysis Using Physics‐Informed Deep Learning

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earthquake‐related phenomena such as seismic waves and crustal deformation impact broad regions, requiring large‐scale 3‐D modeling with careful treatment of the boundaries of the model domain. A deep learning approach known as physics‐informed neural networks (PINNs) has potential for such large‐scale problems involving observational data ...

Symmetries of generalized soliton models and submodels on target space $S^2$

, 2004
Some physically relevant non-linear models with solitons, which have target space $S^2$, are known to have submodels with infinitly many conservation laws defined by the eikonal equation.

On The Pomeron at Large 't Hooft Coupling

, 2010
We begin the process of unitarizing the Pomeron at large 't Hooft coupling. We do so first in the conformal regime, which applies to good accuracy to a number of real and toy problems in QCD.
