Bayesian hierarchical stock–recruitment models for setting conservation limits for Atlantic salmon stocks in Scotland

open access: yesJournal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar L.) populations in Scotland are subject to active management and conservation practices which require biological reference points (BRPs), specifically conservation limits, defined at the level of the stock. Acquiring the data necessary to independently derive these BRPs for all managed populations in Scotland is ...

Blue straggler formation at core collapse

open access: yes, 2016
Among the most striking feature of blue straggler stars (BSS) is the presence of multiple sequences of BSSs in the colour-magnitude diagrams (CMDs) of several globular clusters. It is often envisaged that such a multiple BSS sequence would arise due a recent core collapse of the host cluster, triggering a number of stellar collisions and binary mass ...

Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

open access: yesJournal of Fish Biology, EarlyView.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

Shade variability and stability in interim and definitive tooth‐colored resin‐based restorative materials: Comparing manufacturer‐claimed shades to a universal shade guide

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the shade variability and stability of interim and definitive tooth‐colored restorative materials by comparing manufacturer‐claimed shades to a universal shade guide before and after thermocycling. Materials and Methods Eight commercially available tooth‐colored restorative materials were tested, including conventional ...

Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.
