Reliability‐Aware Framework for Fault‐Tolerant Multi‐Sensor Fusion Using Neuromorphic Hardware‐Native Learning

Advanced Computing, Volume 1, Issue 1, December 2026.
Reliability of training inputs is essential for hardware‐native neuromorphic learning, as faulty data in sensor fusion generates false triggers due to wrong conductance updates. This work presents a reliability‐aware framework ensuring only trustworthy sensor inputs participate in training, preventing false associations and improving robust decision ...

Characterization of the Amazon Rainforest Backscatter at X-Band Using TanDEM-X Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The radiometric calibration of spaceborne SAR products plays a key role for ensuring a good performance of the whole end-to-end system and requires a precise knowledge of both the radar system and the illuminated target on ground.

Fracture and Calving Front Evolution: A Case Study of Fimbul Ice Shelf, Antarctica

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT This study combines historical records, satellite remote sensing data, and inverse modelling to investigate crack formation and calving front evolution of the Fimbul Ice Shelf, Antarctica. Historical maps from the 1950s, together with satellite imagery from 1970s–2026, are used to reconstruct calving‐front positions and track the evolution of ...

White light reduces flight height of birds in low‐density migration corridor

The Journal of Wildlife Management, Volume 90, Issue 8, November 2026.
We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.

Unusual SuperDARN Backscatter During the 11 May 2024 Geomagnetic Storm

Space Weather
A geomagnetic storm, one of the largest in this solar cycle, was launched on 10 May 2024, producing spectacular auroral displays that could be observed across the continental United States (US) at middle and low latitudes.

Deterministic chaos at the ocean surface: applications and interpretations [PDF]

Nonlinear Processes in Geophysics, 1998
Ocean surface, grazing-angle radar backscatter data from two separate experiments, one of which provided coincident time series of measured surface winds, were found to exhibit signatures of deterministic chaos.

Evaluation of Different Radiative Transfer Models for Microwave Backscatter Estimation of Wheat Fields

Remote Sensing, 2020
This study aimed to analyze existing microwave surface (Oh, Dubois, Water Cloud Model “WCM”, Integral Equation Model “IEM”) and canopy (Water Cloud Model “WCM”, Single Scattering Radiative Transfer “SSRT”) Radiative Transfer (RT) models and assess ...

Observation of Daily Flood Hazard During the SWOT Cal/Val Orbit

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Flood peaks can develop and recede within a day, making them difficult to capture with satellites with multi‐day revisit intervals. Here, we exploit daily observations during the Calibration and Validation phase of the SWOT mission to examine a short‐lived flood in May 2023 along the Du Gouffre River in Canada. Despite channel widths below 100
