Multi‐Dimensional Acoustic Cascaded Holographic Encryption with Instantaneous Visual Decryption via Particle Manipulation

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Acoustic holograms act as key tools for information encryption, yet current schemes limit encryption dimensionality/security and require time‐consuming decryption. A compact device integrates multi‐dimensional cascaded acoustic holography with particle manipulation, employs extra secret keys, enables rapid decryption, and is validated via 1D/2D/3D ...

Statistical Auroral Absorption Model Parameterized by AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Energetic electron precipitation, often in association with enhanced geomagnetic activity, leads to increased D‐region ionization in the auroral region causing auroral absorption. A statistical auroral absorption model is presented for high‐latitudes (poleward of 50° magnetic latitude) based on data collected from 2010 to 2019 from 13 wide ...

DRFL: A Dual‐Encryption and Reputation Evaluation Defence Against Malicious Attacks on Federated Learning

IET Communications, Volume 20, Issue 1, January/December 2026.
Federated learning (FL) enables collaborative model training without collecting user data but faces security risks such as privacy breaches, poisoning, and free‐rider attacks. To address these challenges, we propose DRFL, a defense mechanism integrating dual encryption, reputation evaluation and blockchain to enhance security and transparency ...

Mozambique's Colonial‐Era Non‐Human Primate Collection at the National Museum of Natural History and Science of Lisbon: Taxonomy, Provenance, and Historical Context

American Journal of Biological Anthropology, Volume 188, Issue 4, December 2025.
ABSTRACT Objectives This study reviews Mozambique's non‐human primate collection housed at the National Museum of Natural History and Science (MUHNAC) in Lisbon. The collection originates from the Zoological Missions of Mozambique (1948 and 1955) carried out under Portuguese colonial administration. The objectives of this work were to: i.

An Evolutionary Mosaic Challenges Traditional Monitoring of a Foundation Species in a Coastal Environment—The Baltic Fucus vesiculosus

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT During periods of environmental change, genetic diversity in foundation species is critical for ecosystem function and resilience, but it remains overlooked in environmental monitoring. In the Baltic Sea, a key species for monitoring is the brown seaweed Fucus vesiculosus, which forms sublittoral 3D habitats providing shelter and food for fish

Crystal structures of Salmonella enterica FraB deglycase reveal a conformational heterodimer with remarkable structural plasticity at the active site

Protein Science, Volume 34, Issue 9, September 2025.
Abstract The fra locus of Salmonella enterica encodes five genes for metabolism of fructose‐asparagine, an Amadori product formed by condensation of asparagine with glucose. In the last step of this pathway, the FraB deglycase cleaves 6‐phospho‐fructose‐aspartate into glucose‐6‐phosphate and aspartate.

Underground Sagnac gyroscope with sub-prad/s rotation rate sensitivity: Toward general relativity tests on Earth

Physical Review Research, 2020
Measuring in a single location on Earth its angular rotation rate with respect to the celestial frame, with a sensitivity enabling access to the tiny Lense-Thirring effect, is an extremely challenging task. GINGERINO is a large frame ring laser gyroscope,

Ionospheric Scintillation Activity Over Canada in 2019–2023 and Its Potential Influence on Wide Area Augmentation System (WAAS) Navigation Services for Aviation

Space Weather, Volume 23, Issue 7, July 2025.
Abstract Ionospheric scintillation caused by space weather impacts the accuracy and availability of GNSS services and is considered a natural hazard for aviation and other GNSS users. Increased solar activity in 2021–2023, attributed to the ascending phase of the 25th solar cycle, caused an amplification of ionospheric disturbances including the ...
