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 ...

Variational and perturbative formulations of QM/MM free energy with mean-field embedding and its analytical gradients

open access: yes, 2008
Conventional quantum chemical solvation theories are based on the mean-field embedding approximation. That is, the electronic wavefunction is calculated in the presence of the mean field of the environment.

Interfacial Chemistry‐Tailored Silica&Metal‐Based Heterostructures: from Rational Design to Antibacterial Applications

open access: yesSmall, EarlyView.
This review explores how interfacial engineering of silica&metal‐based nanohybrids enables precise architectural control, leveraging the structural and functional contributions of silica to overcome the inherent limitations of meta‐based materials. The antibacterial performance of these nanohybrids including membrane disruption, stimuli‐responsive ...

Inoculation with Arbuscular Mycorrhizal Fungi or Crop Rotation with Mycorrhizal Plants Improves the Growth of Maize in Limed Acid Sulfate Soil

open access: yesPlant Production Science, 2010
Arbuscular mycorrhizal fungi (AMF) improve the uptake of immobile mineral nutrients such as phosphate, thereby improving plant growth. In acid sulfate soil (ASS), AMF spore density is generally low which impacts root colonization and phosphate uptake ...

Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Strongly coupled U(1) lattice gauge theory as a microscopic model of Yukawa theory

open access: yes, 1997
Dynamical chiral symmetry breaking in a strongly coupled U(1) lattice gauge model with charged fermions and scalar is investigated by numerical simulation. Several composite neutral states are observed, in particular a massive fermion. In the vicinity of

Post‐Arc Transient Dielectric Recovery Characteristics of Vacuum Interrupter in the Large‐Capacity Generator Circuit Breaker

open access: yesHigh Voltage, EarlyView.
ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)

Mycorrhizal symbiosis and environmental conditions shape understory herb diversity in a large temperate forest region

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understorey herbaceous plants are a vital component of forest biodiversity in temperate forests. However, the mechanisms underlying their community assembly and species coexistence remain poorly understood.

Accreta centers and maternal morbidity for patients with placenta accreta spectrum disorders in California: a mixed-methods population-based study

open access: yesThe Journal of Maternal-Fetal & Neonatal Medicine
Objective We evaluated whether placenta accreta spectrum (PAS) patients who delivered at accreta centers had reduced severe maternal morbidity (SMM), and we tested for the presence of racial disparity in SMM at these centers.Methods This is a mixed ...
