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

Reviews 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 ...

Wavelet-Based Compressed Sensing for Polarimetric SAR Tomography [PDF]

, 2013
Tomographic synthetic aperture radar (SAR) imaging has been recently formulated in a wavelet-based compressed sensing (CS) framework. This paper reviews the underlying sparsity-driven algorithms for single-channel as well as polarimetric tomography, and ...

Design, Synthesis, and Biological Evaluation of Chiral Urea and Thiourea Derivatives as Multitarget‐Directed Anti‐Alzheimer Agents

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT A series of novel chiral urea and thiourea compounds were designed as multitarget‐directed ligands for Alzheimer's disease and evaluated against hAChE, hBChE, and hMAO‐B, with exploratory assessment of HSD10. These chiral compounds were synthesized and fully characterized, and their enantiopurity was confirmed via HPLC.

Robust Regional Contrast but Penetration‐Sensitive Snow Thickness Over Sea Ice From Multi‐Winter Antarctic CRYO2ICE Observations

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Snow on Antarctic sea ice modulates albedo, thermodynamic growth, and snow–ice formation, yet remains a leading uncertainty in altimetry‐derived sea‐ice thickness. Here we use the post‐2022 CRYO2ICE configuration to derive along‐track winter snow thickness from ICESat‐2 laser and CryoSat‐2 Ku‐band radar freeboards over the Weddell and Ross ...

What SAR Labels Hide About a Changing Arctic

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Synthetic aperture radar (SAR) has been the backbone of Arctic sea ice monitoring since the 1990s, yet nearly every operational product that assigns an ice class or geophysical state (melt onset dates, freeze‐up timing, ice‐type classifications) is derived by compressing continuous radar backscatter into discrete categorical labels.
