Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, EarlyView.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Evidence for increased background neural noise in migraine with aura: Hyperactive but not hyperresponsive

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study had two aims: (1) to investigate the contrast gain in migraine and compare it to that in photosensitive epilepsy; (2) to explore any effects of colored spectacles (precision ophthalmic tints [POT]) on contrast gain. Background Individuals with migraine with aura (MA) typically show high amplitude electrophysiological ...

Development of a theoretical decoupled Stirling cycle engine

Simulation Modelling Practice and Theory, 2011
Abstract The Stirling cycle engine is gaining increasing attention in the current energy market as a clean, quiet and versatile prime mover for use in such situations as solar thermal generation, micro-cogeneration and other micro-distributed generation situations. A theoretical Stirling cycle engine model is developed. Using a theoretical decoupled

Co‐Designing a Model of Brilliant Care for Older People

Journal of Clinical Nursing, EarlyView.
ABSTRACT Aim This study aimed to co‐design a model of brilliant care for older people that provides clear, actionable principles to guide how brilliant care for older people can be realised. Background As the demand for and international importance of care for older people grows, so too does the negative discourse about care for older people.
