Modified Morphological Component Analysis Method for SAR Image Clutter Suppression

The morphological component analysis (MCA) method can be used to suppress the clutter in a synthetic aperture radar (SAR) image when the dictionaries of clutter and target components are mutually incoherent. However, the effectiveness of the conventional

Coupling Exponential Rolling Circle Amplification to Lateral Flow Devices for Point‐of‐Care Detection of Viral RNA

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
A new exponential RCA (E‐RCA) system was developed and coupled to a toehold system for release of a bridging DNA, allowing for lateral flow detection. The E‐RCA method uses a secondary primer (P2) that binds RCA products (RCAP) to generate extended P2 products that can re‐prime a partially self‐complementary circular template, generating a complete ...

From barriers to benefits: A personalized sleep intervention enhances sleep duration and emotional health in chronic short sleepers

British Journal of Psychology, Volume 117, Issue 4, Page 1469-1494, November 2026.
Abstract This pilot study evaluated a personalized sleep intervention incorporating motivational interviewing techniques to address sleep barriers, along with tailored sleep hygiene and extension for chronic short sleepers. Eleven university students completed a 14‐day sequential intervention (baseline, sleep hygiene and a combined phase adding 90‐min ...

Real and Apparent Deviations From Rational Choice

Kyklos, Volume 79, Issue 4, Page 1153-1178, November 2026.
ABSTRACT This paper offers a taxonomy of real and apparent deviations from rationality. The taxonomy is based on three axes of divides—whereas the axes are successive refinements. The outermost‐axis divide delineates “anxiety‐based choices” from “anxiety‐free choices.” Anxiety‐based choices are real deviations such as the Allais and Ellsberg paradoxes ...

Mapping Trail Networks From Crowdsourced Hiking GPS Traces

Transactions in GIS, Volume 30, Issue 7, November 2026.
ABSTRACT Reconstructing trail networks from GPS data is a challenging task due to the heterogeneity, sparsity, and noise inherent in crowdsourced traces. To address the dichotomy between maintaining topological connectivity and handling severe geometric noise, we present two complementary approaches for automatic trail map generation from large‐scale ...

Wide‐Angle Domain Compatible Flexible Multispectral Stealth Metasurface for Visible Light, Laser, and Microwave

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
A flexible, wide‐angle‐compatible multispectral stealth metasurface is proposed. It achieves visible camouflage and stable cooperative stealth of 10.6 μm laser and X‐band microwave across the 0°–60° incident range via layered wavelength decoupling. ABSTRACT As electromagnetic detection systems evolve toward multispectral integration and 0°–60° wide ...
