Extended‐Range Thermometry via Dual Er Fluorescence of Oxyfluoride Glass‐Ceramic Optical Fibers

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
A dual‐channel Yb3+‐Er3+‐based optical fiber thermometer combines visible upconversion and infrared photoluminescence for wide‐range temperature sensing. Yb3+/Er3+‐doped LaF3 or NaLuF4 nanocrystals embedded in transparent glass‐ceramic optical fibers enable reliable operation from room temperature up to 800 K, offering enhanced sensitivity and spectral

Kelsen Before Kelsen – Reflections on Hans Kelsen's Die Staatslehre des Dante Alighieri

Victoria University of Wellington Law Review, 2019
In this article, I reflect on Hans Kelsen's first work, Die Staatslehre des Dante Alighieri, which was written in 1905 while he was still a student. There is no English translation of Die Staatslehre. These "reflections" based on the Italian edition of the book are dedicated to the honour of a scholar and a gentleman, Gordon Anderson.

Ageing exacerbates the adverse effects of respiratory muscle fatigue on vascular function, locomotor muscle fatigue and exercise performance in males

Experimental Physiology, Volume 111, Issue 1, Page 283-299, 1 January 2026.
Abstract This study investigated the effect of respiratory muscle fatigue on cardiovascular function, locomotor muscle fatigue and exercise performance in young and master athletes, a model of successful ageing. Ten young male (YA, 27.4 ± 4.4 years) and 11 male master endurance athletes (MA, 65.0 ± 5.1 years) performed, on separate days, two constant ...
