Parametrization and penalties in spline models with an application to survival analysis [PDF]

open access: yes, 2008
In this paper we show how a simple parametrization, built from the definition of cubic splines, can aid in the implementation and interpretation of penalized spline models, whatever configuration of knots we choose to use.

Laser‐Induced Breakdown Spectroscopy (LIBS) for Rapid Food Safety Monitoring: Advancements, Applications, and Future Directions

open access: yesFood Safety and Health, Volume 4, Issue 1, Page 50-66, January 2026.
Laser‐induced breakdown spectroscopy (LIBS) emerges as a transformative tool for rapid, on‐site pesticide residue detection in food, offering real‐time screening with minimal sample preparation and eliminating solvent use. Although LIBS demonstrates detection limits (0.009–6.9 mg/kg) suitable for regulatory screening and aligns with green chemistry ...

Effects of salmon lice on numbers and size distributions of Atlantic salmon returning to spawn in Norwegian rivers

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
This study presents a quantitative relationship between infestations of post‐smolt recruits and size‐structured returns of mature salmon to Norwegian rivers, suggesting that louse infestation from farms may reduce returns of spawners and re‐structure the size distribution of mature river populations of Atlantic salmon.
