Progressive Colour Equalisation and Detail Refinement for Underwater Image Enhancement

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Underwater image enhancement remains a critical challenge in computational vision due to complex distortions caused by wavelength‐dependent light absorption and scattering. This paper introduces CEDFNet, a novel two‐stage framework that leverages advanced computational intelligence techniques for robust and high‐fidelity underwater image ...

Corrosion Failure Analysis of Contactor Type Electrical Connection Components Used in Converter Valve Side Bushings

open access: yesHigh Voltage, EarlyView.
ABSTRACT As a commonly used bushing current‐carrying structure in recent years, contactor‐type electrical connection parts operate in a complex environment of electric, thermal and chemical corrosion for extended periods. With the increase of ultra‐high voltage (UHV) transmission capacity, its operating environment faces more stringent challenges, and ...

Quantum refinement with electron diffraction and X‐ray free‐electron laser data: comparative study of ribonucleotide reductase dimetal site

open access: yesJournal of Applied Crystallography, EarlyView.
For the first time quantum refinement has been performed with X‐ray free‐electron laser and microcrystal electron diffraction data for the dinuclear iron site in the R2a protein of ribonucleotide reductase. The method is shown to work well and can be used to determine the protonation state of the bridging solvent molecule and deduce photoreduction in ...

Social information about others' affective states in a human‐altered world

open access: yesJournal of Animal Ecology, EarlyView.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Effects of temperature and browning on the functional response of a freshwater top predator

open access: yesJournal of Animal Ecology, EarlyView.
This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
