Defense heterosis as a novel plant protection strategy: From theory to breeding practice

New Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance

Progress in Photovoltaics: Research and Applications, EarlyView.
We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...

Sb2Se3 Thin Films for Doping the Absorber in CdTe Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
This study introduces for the first time a new doping route for CdSeTe/CdTe solar cells: A thin Sb2Se3 layer is deposited on the absorber, diffusing Sb into CdTe via subsequent CdCl2 treatment. With this approach, Sb‐doped devices reach efficiencies as high as conventional Cu‐doped cells, while showing much greater stability under accelerated ...

Seasonal hindcasts to assess the hazard of meteorological drought over Europe: A multimodel approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An application of seasonal hindcasts is presented for assessing the hazard of meteorological drought at the regional scale across Europe. The realism of seasonal hindcasts from five contributors to the Copernicus Climate Change Service is assessed through a rigorous workflow.

The SKAO Pulsar Timing Array

The Open Journal of Astrophysics
Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequencies, with secondary goals of undertaking other fundamental tests of ...

Impact of Device Architecture on Proton Detection Efficiency in 2D Perovskite Thick Film Detectors

Small, EarlyView.
This work shows the role of device architecture in MeV proton detection with 2D perovskite thick (> 1 µm) films. A direct comparison between planar and stacked devices demonstrates that the stacked geometry achieves superior response by enabling more efficient charge collection and better exploitation of the active layer volume, ensuring stable and ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Evaluating student involvement in sea‐level data rescue

Weather, EarlyView.
Digitising historical tidal data are essential for tracking sea‐level rise and understanding long‐term climate trends. This study develops a framework to train undergraduate students in digitising tidal marigrams from Kilrush (County Clare) and Dún Laoghaire (County Dublin) Harbours. Students tackled challenges like misidentification, formatting errors
