Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.The PLMC protocol is implemented using a four‐level system within the 7F0↔5D0${}^7F_0 \leftrightarrow {}^5D_0$ optical transition of 151Eu3+$^{151}\mathrm{Eu}^{3+}$ ions (site 1) in the 0.1%‐doped Eu3+${\rm Eu}^{3+}$:Y2SiO5${\rm Y}_2{\rm SiO}_5$ crystal, and the experimental pulse sequence includes two distinct stages: (i) pre‐creation of macroscopic ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract We present array‐scale (∼500 × 500 km) anisotropic shear‐velocity models from two Pacific ocean‐bottom seismometer (OBS) arrays of the OBS Research in the Convecting Asthenosphere (ORCA) experiment: Young ORCA (∼43 Ma) and Old ORCA (∼90 Ma). Rayleigh‐wave phase velocities spanning 5–150 s are combined with Love‐wave phase velocities from 5 to ...

Basal Force Probability Distributions in Thin‐Layer Granular Flows
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.Abstract Extreme geophysical flows, such as granular and debris flows, can significantly shape the landscape in steep lands and generate seismic signals that can be recorded over long distances. However, direct field measurements needed to constrain the granular physics remain difficult due to the damage potential of those flows.

Learning Vertical Coordinates via Automatic Differentiation of a Dynamical Core
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract Terrain‐following coordinates in atmospheric models often imprint their grid structure onto the solution, particularly over steep topography, where distorted coordinate layers can generate spurious horizontal and vertical motion. Standard formulations, such as hybrid or SLEVE coordinates, mitigate these errors by using analytic decay functions

Radio Science, Volume 61, Issue 8, August 2026.Abstract This paper explores the impact of natural phenomena on signal data transmission across various ionospheric communication channels. The study focuses on three primary phenomena: meteor trails prevalent in the middle‐ and lower‐latitude ionosphere, bubble and plume structures observed around the equatorial ionosphere, and magnetic‐storm‐induced ...

Tectonics, Volume 45, Issue 8, August 2026.Abstract Rayleigh‐Taylor instabilities within the upper mantle are investigated as a mechanism for the uplift of rift‐margin mountain ranges within the continents. Our focus is on the Transantarctic Mountains (TAM). These mountains form at the margin between East and West Antarctica and have been free from the effects of subduction for about 500 ...
