Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems
Laser &Photonics Reviews, EarlyView.Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Intraguild interactions shape vocal output and diel activity patterns in sympatric forest owls
Oikos, EarlyView.Competition and intraguild predation among sympatric predators may force smaller, subordinate predators to reduce interactions with larger, dominant species via restricted spatial or temporal activity (acquiescence hypothesis). Simultaneously, dominant predators may actively exclude subordinate competitors through frequent vocal and physical aggression

People and Nature, EarlyView.Abstract The first edition of the Ordnance Survey's 1:2500 County Series is marked with treed areas, such as woodlands and orchards, and, remarkably, freestanding trees. Consequently, it is an unparalleled source of information on the distribution of trees across Britain in the mid‐late nineteenth century, when the maps were first surveyed. In order to

Caring with forests: Human and more‐than‐human care in forest occupations in Germany
People and Nature, EarlyView.Abstract Drawing on ongoing ethnographic and participatory action research within forest occupations in Germany, this paper develops the concept of ‘caring with forests’ to theorise the mutual, multidimensional relationships of care that emerge between humans and more‐than‐human beings in environmental protest settings.

QUALITY ADJUSTED PRICE INDICES FOR DOUGLAS-FIR TIMBER [PDF]
The purpose of this paper is to determine if there have been systematic changes in the characteristics of Douglas-fir stumpage sold on National Forests in the Pacific Northwest that would significantly bias the price of stumpage.

PLANTS, PEOPLE, PLANET, EarlyView.Forest plantations play an increasingly important role in climate change mitigation through carbon sequestration, yet management strategies that enhance long‐term ecosystem carbon storage remain insufficiently understood. We investigated the effects of more than a decade of close‐to‐nature management on community structure and ecosystem carbon storage ...

PLANTS, PEOPLE, PLANET, EarlyView.As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...
