Multicenter Assessment of Combined Brain and Cervical Spinal cord 3T MP2RAGE T1 Measurements for Reliable Tissue Microstructure Quantification

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Reliability of simultaneous brain and spinal cord magnetization‐prepared two rapid acquisition gradient echoes (MP2RAGE) T1 measurements was evaluated in a multicentre context. Mean intra‐site/inter‐site/between‐participant coefficients of variation (COV) were 0.4/0.9/2.3% for the brain ROIs and 2.0/2.4/1.7% for the cSC, confirming the potential of T1 ...

Spatial Econometric Analysis of Regional Aging: Evidence From German Counties

Population, Space and Place, Volume 32, Issue 6, August 2026.
ABSTRACT Regional demographic change is widely acknowledged to contribute to economic decline, making an understanding of the determinants of regional population aging crucial for designing effective policy interventions. However, research on these determinants remains limited, particularly at the sub‐national level.

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.

Fine‐Tuning a Weather Foundation Model With Lightweight Decoders for Unseen Physical Processes

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Recent advances in AI weather forecasting have led to the emergence of so‐called “foundation models”, typically defined by expensive pretraining and minimal fine‐tuning for downstream tasks. However, in the natural sciences, a desirable foundation model should also encode meaningful statistical relationships between the underlying physical ...
