Aerosol Retrieval Over Ocean From DPC‐2/GF‐5(02): Using RemoTAP Extended With a 3‐Parameter Ocean Bio‐Optical Model and Comparisons With a 1‐Parameter Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Multi‐angle polarimetric instruments (MAPs) enable the retrieval of essential aerosol properties over oceanic regions. MAPs retrieval algorithms commonly use a 1‐parameter ocean bio‐optical model (OBM), based on chlorophyll‐a concentration only to represent optical properties over open waters (case‐1), whereas the coastal water (mixture of ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

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.
