A Low‐Cost and Compact High‐Frequency Gallium Nitride Gradient Power Amplifier for Low‐Field MRI

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2992-2999, May 2026.
ABSTRACT Purpose To reduce the upfront cost of small, low‐field MRI systems, while expanding the capabilities of their gradient systems. Methods A gradient power amplifier was designed to leverage the lowering cost of Gallium Nitride (GaN) power transistors and high speed logic, to achieve high efficiency and responsiveness for driving gradient coils ...

The Epistemic Generativity of Using a Model of a Big Idea

Science Education, Volume 110, Issue 3, Page 803-825, May 2026.
ABSTRACT Science instruction should involve learners in generating and warranting ideas, what we call epistemic generation. In modeling instruction, epistemic generation should be achieved by coordinating a model structure with the experienced world in reciprocal directions denoted as developing models and using models. In the former, a model structure

Archives of impact: The politics of craters on Earth

Geographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.
