From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

Oikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, EarlyView.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

Separation Maps for Classification of Multiple Partial Discharges: A Comparative Study Focusing on Time and Frequency Characteristics

High Voltage
Electrical insulation faults produce partial discharges (PD), which can be analysed to identify specific types of defects. PD clustering is a widely used method to identify PD sources, although its success depends largely on the feature maps used.

Directive Antenna Clutter Loss in Slant Paths

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.
