Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

PLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

Packaging Technology and Science, EarlyView.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond

The benefits of a hybrid‐3DEnVar data assimilation scheme for the convection‐permitting NWP model AROME–Austria

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The climatological‐error covariance matrix used in three‐dimensional variational data assimilation (3DVar) provides smooth and isotropic increments spread to long distances. In contrast, three‐dimensional ensemble variational data assimilation (3DEnVar) with a purely ensemble‐error covariance matrix provides inhomogeneous increments and contains the ...

Multiscale numerical sensitivity simulations of a mesoscale gravity‐wave event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
High‐resolution WRF simulations of the February 14–15, 1992 STORM‐FEST event show that mesoscale gravity‐wave genesis occurs via geostrophic adjustment within an upper‐level unbalanced jet, while wave ducting governs maintenance. High‐resolution (1 km), improved physical parameterization, and targeted sensitivity simulations demonstrate that upstream ...

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 ...

Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Polarity‐Engineered, Tribo‐Positive Imidazolium‐Mediated Crosslinked 6FDA‐Durene Films for Triboelectric Nanogenerator

Small, EarlyView.
Imidazolium‐mediated crosslinking transforms 6FDA‐durene PI from tribo‐negative to tribo‐positive by modulating the surface electronic structure and charge‐transfer behavior. DFT calculations confirm the experimentally observed polarity transition.

Do Product Market Reforms Work? Assessing Regulatory Changes Impacting Competition

Southern Economic Journal, EarlyView.
ABSTRACT We create a new dataset that characterizes studies of product market reforms implemented from 1932 to 2011. We examine the size and origins of differences in estimated impacts based on an OECD classification scheme for potentially competitive restrictions of regulation. The median impact from switching to a pro‐competitive environment is a 19%
