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 ...

Preprocessing Procedure for Propagation Measurements on MEO Satellite Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with

Exploration of Copper Halide Linear‐Array Detector Prototype for Security Checks

Small, EarlyView.
Mn‐doped Cs3Cu2I5 is demonstrated as a highly promising scintillator for X‐ray imaging, featuring high light yield, a low detection limit, and negligible afterglow. A linear‐array detector prototype based on the Mn‐doped Cs3Cu2I5 delivers a spatial resolution of 1.1 lp/mm in food‐safety and security inspections, marking a significant advance in the ...

Accounting for Friendlessness: Stigma and the Quest for an Honorable Self

Symbolic Interaction, EarlyView.
How do people who identify as friendless make sense of their condition in a moment when friendship is extolled for the support and satisfaction it offers? This article draws on interviews with 21 adults in an Atlantic Canadian city. We argue that our interviewees were rarely at ease with their friendlessness and were at pains to recover an honorable ...

Enhancing the Cherenkov over scintillation ratio using dichroic filters in BGO and TlCl for TOF-PET

Scientific Reports
The Cherenkov emission in inorganic crystal scintillators has been shown to dramatically improve time resolution for time-of-flight positron emission tomography (TOF-PET) for in slow scintillators with a high refractive index such as bismuth germanium ...
