“I Was Known to be a G**k Lover”: Histories of Asian–Australian War Bride Marriages During the Vietnam War

open access: yesAustralian Journal of Politics &History, EarlyView.
Marriage has long been a legacy of overseas deployment for Australian servicemen. In the case of the war in Vietnam, Australian men often interacted with local women on base, in civilian spaces, or in passing. Occasionally, couples would form private relationships and, in some cases, marry and return to Australia at the end of deployment.

Imaging malaria parasites across scales and time

open access: yesJournal of Microscopy, EarlyView.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

Cumulative degradation of electrical properties in polypropylene insulation for AC cables under repeated impulse voltage stress

open access: yesHigh Voltage, Volume 10, Issue 3, Page 623-631, June 2025.
Abstract In modern power transmission systems, AC cables are increasingly integrated with overhead lines, forming hybrid networks. These cables are frequently exposed to repeated impulse voltages from the overhead lines. While surge arresters offer partial protection, the long‐term effects of these impulses on polypropylene (PP) insulation remain ...
