Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

GIA‐Induced Mantle Circulation and Surface Horizontal Motions in North America: Effects of 3D Laterally Varying Elastic Thickness and Viscosity

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The horizontal surface motions of the Earth's crust induced by glacial isostatic adjustment (GIA) are highly sensitive to lateral variations in Earth properties. We construct 3D GIA models by incorporating both varying elastic lithospheric thickness and lateral viscosity variations in the asthenosphere in a global, compressible, self ...

Mapping Global GNSS Vertical Velocities to Solid Earth Figure Change

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Earth's figure evolves in response to glacial isostatic adjustment (GIA), surface‐mass redistribution, and rotational and mantle‐driven processes. While temporal changes in the geoid's flattening are monitored through low‐degree gravity field harmonics, the geometric response of the solid Earth can be assessed independently from GNSS ...

Interval Data Assimilation: A Data Assimilation Scheme Where All Observations Are Intervals

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract With the proliferation of non‐conventional observations from low‐cost sensors, citizen science networks, and binary detection systems, data assimilation increasingly confronts observations that take the form of inequalities or intervals rather than precise point values.

Fine‐tuning ab initio XANES spectra calculations using the Bayesian optimization algorithm

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 5, Page 1455-1466, September 2026.
A Bayesian optimization technique is used to tune the FEFF and FDMNES packages and to improve matching between theoretical and experimental spectra. The tests were performed on monometallic Ni, Fe and Pd K‐edge XANES spectra using several different spectrum similarity metrics.Theoretical modeling of X‐ray absorption near‐edge structure (XANES) spectra ...

Focusing, collimation, and beam expansion of high‐energy X‐rays with diamond refractive lenses

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 5, Page 1326-1337, September 2026.
The effectiveness and versatility of diamond refractive optics for high‐energy X‐rays (> 40 keV) is presented in applications to focusing, collimation, and beam expansion, along with design and implementation details.Diamond is extremely well suited for synchrotron X‐ray refractive optics.
