Gaia: segmented germanium detector for high‐energy X‐ray fluorescence and spectroscopic imaging

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 1, Page 91-97, January 2026.
We present Gaia, a cryogenically cooled monolithic array of 96 high‐purity germanium pixel detectors integrated with a custom low‐noise application‐specific integrated circuit and a field‐programmable gate array‐based data acquisition system. The system achieves an average energy resolution of 711 eV at 122 keV and 253 eV at 5.89 keV, and serves as the

Biodiversity–food trade‐offs when agricultural land is spared from production

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 1, Page 254-284, January 2026.
Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

Development of the alcohol‐free and low‐alcohol drinks market in Great Britain from 2011 to 2022: Narrative timelines based on a documentary review of off‐trade retail magazines and market intelligence reports

open access: yesDrug and Alcohol Review, Volume 45, Issue 1, January 2026.
Abstract Issue There is a growing alcohol‐free and low‐alcohol (no/lo) drinks market in Great Britain. Insight about when this emerged and how it has developed is needed to inform and interpret the growing body of research into the use of no/lo drinks. We therefore document the development of the no/lo market in Great Britain between 2011 and 2022 and ...

Thermal analysis of stirling cycle regenerators

open access: yes, 2020
Stirling cycle cryocoolers are used widely in military applications. The regenerator is the key element of Stirling cycle cryocoolers. It is known that performance of the regenerator directly affects the cryocooler performance. Therefore, any improvement on the regenerator will lead to a more efficient cryocooler.

Liberal Institutionalism in Crisis: Reassessing the Iran‐West Nuclear Standoff Amid the 2025 Israel–Iran War

open access: yesDigest of Middle East Studies, Volume 35, Issue 1, Winter 2026.
ABSTRACT The Israel‐Iran war of 2025 has changed the geopolitical face of the Middle East, not only bringing up the issue of nuclear proliferation, but also putting international diplomacy to the test. This essay assesses the performance of liberal institutionalism based on the latest conflict, paying special attention to the Joint Comprehensive Plan ...
