River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

High Voltage, EarlyView.ABSTRACT Dissolved gas analysis (DGA), widely used for fault diagnosis, can be significantly influenced by the presence of oxygen. Oxygen not only accelerates fluid degradation but also alters the type and concentration of fault gases generated, potentially leading to misinterpretation of transformer conditions if conventional DGA models are applied ...

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 780, October 2026 Part A.An energy‐conserving discrete framework for the vertical discretisation of stratified ocean models is developed using internal gravity‐wave theory. A β$$ \beta $$‐indexed family of schemes is analysed through perturbation theory, revealing optimal parameter choices and grid designs that reduce truncation errors significantly.

Different Attentional and Memory Processes When Learning From a Peer or an Adult in Children
Infant and Child Development, Volume 35, Issue 5, September/October 2026.ABSTRACT Both adult–child and child–child interactions support learning, yet it remains unclear whether children engage distinct cognitive strategies depending on the social context. In this study, 62 children aged 6–12 years, tested in Switzerland, completed a memory task in which novel objects were introduced by either a child or an adult speaker ...
