Teleseismic S‐Wave Coda Autocorrelation and vp/vs ${v}_{p}/{v}_{s}$ Distribution Over the Antarctic Ice Sheet

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Accurate characterization of the compressional to shear (P‐to‐S) wave‐speed ratio (vp/vs ${v}_{p}/{v}_{s}$) within the Antarctic Ice Sheet (AIS) is crucial for understanding its internal structure, mechanical stability, and vulnerability to a changing climate.

Submarine Flank Collapses at Tagoro Volcano: Insights From Bathymetric Surveys and 3D Multiphase Simulations

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.

YOLO‐Based Detection and Localization of Rocket Induced Traveling Ionospheric Disturbances

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract During rocket launches, atmospheric disturbances significantly impact the ionosphere, generating Traveling Ionospheric Disturbances (TIDs). These disturbances can affect radio communications and navigation systems and may pose risks to high‐speed aerospace vehicles.

Localization and Classification of Gravity Wave Events From VIIRS Day/Night Band Satellite Imagery Using Machine Learning Techniques

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Gravity waves in the upper mesosphere produce diverse spatial patterns in nighttime airglow, but their global morphology has been difficult to characterize because manual identification is impractical for the massive satellite image archive. We developed a machine learning framework to detect and classify gravity wave events in imagery from ...

Convergent‐beam X‐ray crystallography

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1200-1218, August 2026.
Molecular crystal diffraction with a highly focused X‐ray beam decouples crystal morphology and molecular structure by measuring magnified topographs from every reflection.Molecular and polymeric crystals show a wide range of functional properties that arise from the interplay between the atomic‐scale structure of their constituent molecules and the ...

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, Volume 104, Issue 5, Page 498-509, August 2026.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Numerical Anisotropy and Band‐Gap Formation in Finite Element Wave Propagation: Analysis and Mitigation Using Spline‐Based Elements

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Numerical anisotropy and dispersion are inherent consequences of spatial discretization in finite element modeling of wave propagation. In two‐dimensional problems, these effects manifest not only as direction‐dependent phase and group velocities but also as angularly dependent numerical band gaps that may entirely suppress wave propagation ...
