Proposed Diagnostic Reference Levels for Frequently Performed Paediatric Radiographic Examinations

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Paediatric diagnostic reference levels (DRLs) are weight‐stratified dose levels for typical medical imaging examinations for broadly defined types of equipment. The 75th percentiles of the FRLs across the nine X‐ray units from five centres in Australia were calculated as the proposed Local DRLs (LDRLs).

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

open access: yesThe Journal of Wildlife Management, EarlyView.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Mode‐Locked Pulse Generation in Plasmonic Lattices

open access: yesLaser &Photonics Reviews, EarlyView.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

Data‐Driven Engineering of Thermostable Collagen‐Mimetic Peptoid Triple Helices

open access: yesMacromolecular Rapid Communications, EarlyView.
Data‐driven active learning discovery of collagen‐mimetic peptoids capable of forming a thermostable collagen‐like triple helix using computational screening followed by experimental validation. ABSTRACT Collagen‐mimetic peptides (CMPs) are engineered molecules designed to replicate the triple‐helical structure of natural collagen.
