Where numerical weather prediction meets large‐eddy simulations in a convective boundary layer during the FESSTVaL field experiment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We exploit the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL) to compare the performance of an NWP model at sub‐km resolutions with a traditional LES model. Focusing on clear‐sky ABL turbulence (June 14), shallow convective clouds and surface radiation (June 27), and deep convective cold pools (June 29), we find ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films

open access: yesRare Metals, EarlyView.
ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass

open access: yesRare Metals, EarlyView.
ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

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

open access: yesInternational 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 ...

Design of Experiments (DoE)‐Optimized Polymeric Oxytocin Nanoparticles for Enhanced Nose‐to‐Brain Delivery

open access: yesSmall, EarlyView.
Intranasal (IN) delivery of PEGylated PLGA nanoparticles (NPs) loaded with oxytocin (OT) (OT‐NP‐PEG) is investigated as a strategy to enhance OT transport to the brain for treating autism and other neuropsychiatric disorders. The optimized NP formulation demonstrates appropriate physicochemical characteristics, improved stability, and enhanced mucosal ...
