Interference and Multipath Resilient ToA Estimation
CoRRWe present a computationally-efficient algorithm for time-of-arrival (ToA) estimation that is robust under multipath propagation and strong interference. Our algorithm leverages multiple receive antennas to combine adaptive spatial filtering with autodifferentiation in order to super-resolve the tap of the first-arriving path at low computational ...

Evaluating the Role of Kernel Choice on Radiative Feedback Estimates
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Radiative feedbacks are important for understanding climate sensitivity, yet estimates vary widely across climate models. Feedbacks are often computed using the radiative kernel technique, which uses pre‐calculated radiative sensitivities (kernels) derived from different models and base states. While much attention has been given to intermodel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.Abstract Climate models have substantial biases in downwelling shortwave radiation over the Southern Ocean (SO) and Antarctica, primarily due to their inability to accurately represent the frequent occurrence of low‐level mixed‐phase clouds. Building on the evaluation of the Unified Model (UM) Regional Atmosphere and Land version 3 (RAL3), this study ...

Wind‐Driven Circulation Feedbacks Offset Tropical Geoengineered Sea Salt Emissions
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.Abstract Using a NOAA Geophysical Fluid Dynamics Laboratory coupled atmosphere–ocean (CM4) comprehensive model, we employ simulations of enhanced, geoengineered sea salt aerosol (SSA) emissions in the tropics to examine the circulation response to idealized marine cloud brightening. Increased tropical SSA emissions cool the deployment region and weaken

Morphology‐Driven Ternary Pattern Space Spans Shallow Marine Clouds
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.Abstract Marine shallow clouds exhibit a variety of patterns, which have been the subject of extensive research. In this study, we introduce a new approach for their continuous classification using Moderate Resolution Imaging Spectroradiometer (MODIS) true color imagery.

Advanced Science, Volume 13, Issue 51, 14 September 2026.This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.

Sources of ToA estimation error in LoS scenario
, 2010 Time-of-arrival (ToA) estimation technique used with ultra-wideband (UWB) transmission can be used for accurate indoor ranging. In the indoor multipath rich environment, these techniques often suffer from significant inaccuracy in ranging estimation.
