arXiv:2606.08711v1 Announce Type: new Abstract: Correcting numerical dispersion artifacts from Finite Difference solvers is a well-identified challenge in computational wave physics, but existing approaches evaluate only a restricted family of CNN-based architectures and have been applied exclusively to the elastic wave equation. We instantiate the Deep Finite Difference framework on two-dimensional anisotropic acoustic wave propagation, pairing a fourth-order Finite Difference proxy with a...

arXiv:2606.08711v1 Announce Type: new Abstract: Correcting numerical dispersion artifacts from Finite Difference solvers is a well-identified challenge in computational wave physics, but existing approaches evaluate only a restricted family of CNN-based architectures and have been applied exclusively to the elastic wave equation. We instantiate the Deep Finite Difference framework on two-dimensional anisotropic acoustic wave propagation, pairing a fourth-order Finite Difference proxy with a Pseudo-Spectral reference over 27,000 heterogeneous velocity fields. We benchmark twelve correction architectures, from linear regression to Fourier Neural Operators, under a unified 10-fold cross-validation protocol.

NASA addresses criticism over all-male crew selected for Artemis III test mission

When NASA’s Artemis III mission launches next year, the crew won’t include any women — a revelation that sparked controversy after the agency on Tuesday announced the four astronauts selected for the flight. “Not a single woman flying on Artemis III is an insane choice,” Alexandra Doten, a space influencer who goes by Astro Alexandra, posted on X on Tuesday. NASA Administrator Jared Isaacman attempted to address these criticisms head-on Wednesday.

Jeffery Lee breathes ‘sigh of relief’ after Alabama’s nitrogen execution deemed unconstitutional

A death row prisoner whose planned execution on Thursday was suddenly halted became emotional when he learned that a federal court had ruled Alabama’s use of nitrogen gas violates the constitutional ban on cruel and unusual punishment. “It’s like an expected sigh of relief in one aspect, and then you still got to stay and maintain your focus and continue to fight,” Jeffery Lee, who has been on death row for nearly three decades, told NBC News by phone Tuesday. He spoke from the William C....
