Ultra High‐Resolution Ultrasound Features of Carpal Tunnel Syndrome in Transthyretin Amyloidosis: A Cross‐Sectional Study

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Transthyretin amyloidosis (ATTR), including hereditary (hATTR) and wild‐type (wtATTR), often presents initially as carpal tunnel syndrome (CTS), often preceding systemic symptoms by several years. Ultra high‐resolution ultrasound (UHRUS) offers detailed visualization of peripheral nerve morphology, but its application in ATTR‐

Fabrication of amorphous lamellar freestanding poly(N‐dodecyl acrylamide) films and their mechanical properties

Polymer International, EarlyView.
A freestanding film of completely uniaxially oriented amorphous lamellae was produced. The film exhibited enhanced tensile strength with increasing orientation of the lamella. Abstract An amorphous lamellar freestanding film composed of poly(N‐dodecyl acrylamide) (pDDA) was prepared by annealing a micrometer‐thick film under humid conditions (humid ...

Azole antifungal contaminants disrupt mycorrhizal function and risk agricultural sustainability

PLANTS, PEOPLE, PLANET, EarlyView.
Global food production is increasingly threatened by soil degradation, climate change and the rising costs of synthetic fertilisers. Circular agriculture, which promotes resource reuse, is a promising solution, but using treated wastewater and biosolids in farming introduces risks from emerging contaminants like pharmaceutical residues.

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...
