Multi‐scale geophysical mapping of the brine and bedrock surfaces along the Dolores River, Paradox Valley, Colorado, December 2023

Near Surface Geophysics, Volume 24, Issue 1, Page 36-49, February 2026.
Abstract Total dissolved solids derived from salt dome–sourced brine in the underlying alluvial aquifer substantially increase with distance in the reach of the Dolores River that passes through Paradox Valley in southwestern Colorado. The area has been the site of salinity control operations since the 1990s to reduce salt loading to the downstream ...

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

Time and phase alignment of distributed gateways: Theoretical analysis and experimental demonstration

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 47-59, January/February 2026.
The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

Coherent Spin Waves in Curved Ferromagnetic Nanocaps of a 3D‐Printed Magnonic Crystal

Small, Volume 22, Issue 7, 2 February 2026.
A nanoprinted 3D magnonic woodpile crystal is measured by microresonator ferromagnetic resonance. Micromagnetic simulations are performed to analyze and visualize the detected coherent spin‐wave modes along the nickel‐coated tubes and caps for various field angles. The woodpile exhibits an unexpected phase evolution and robust edge modes.

Academic Freedom as a Contested Public Good: Ideology, Trust and Public Attitudes in the UK and Japan

Politics &Policy, Volume 54, Issue 1, February 2026.
ABSTRACT Academic freedom is widely regarded as a cornerstone of democratic society, yet its public legitimacy remains contested. This article examined how citizens in two democracies (Japan and the United Kingdom) understand and evaluate academic freedom across different issue domains.
