Wave‐Based Quantification of Ion Composition in the Earth's Magnetosphere‐Ionosphere‐Coupling Region

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Ion composition critically determines the basic kinetic characteristics of plasma and affects energy transmission of the magnetosphere. However, it exhibits significant variations with altitude, latitude, local time, longitude, and also with geomagnetic and solar activity.

Foreshock Migration Preceding the 2025 Mw 8.8 Kamchatka Earthquake: Insights From Single‐Station Observations

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We investigate the spatiotemporal evolution of foreshocks preceding the 2025 Mw 8.8 Kamchatka earthquake by applying single‐station analysis to waveforms recorded at the nearest seismic station. Our results reveal a southwestward migration of foreshocks toward the mainshock epicenter through multiple stages, with a migration speed of ∼7.0 km ...

Observations of Coherence Changes in C‐Band SAR Linked to Snow Thermodynamics and Wind Redistribution on First‐Year Sea Ice

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We present novel observations of C‐band Synthetic Aperture Radar (SAR) coherence sensitivities and patterns for snow on first‐year sea ice (FYI) consistent with snow thermodynamics and wind redistribution. Wintertime SAR coherence and backscatter change observations of landfast FYI in Dease Strait, Nunavut, Canada are made using 12‐day repeat ...

Synthesis, Structure, and Thin Film Optical Properties of a Chiral Benzothiazole‐Derived Squaraine

ChemPhysChem, Volume 27, Issue 7, 14 April 2026.
Solution‐processed thin films can be sensitive to the choice of solvent and thermal annealing, which we explore for a chiral benzothiazole squaraine. We observe peculiarly shaped excitonic circular dichroism in uniaxially anisotropic thin films, in which the presumed Davydov bands are spatially distributed exclusively into in‐plane (UDC) and out‐of ...
