Intraoperative radiation therapy with 50 kV x‐rays: A multi‐institutional review

Journal of Applied Clinical Medical Physics, Volume 25, Issue 3, March 2024.
Abstract This report covers clinical implementation of a low kV intraoperative radiation therapy (IORT) program with the INTRABEAM® System (Carl Zeiss Meditec AG, Jena, Germany). Based on collective user experience from eight institutions, we discuss best methods of INTRABEAM quality assurance (QA) tests, commissioning measurements, clinical workflow ...

Intracycle RPM control for vertical axis wind turbines

Wind Energy, Volume 27, Issue 3, Page 202-224, March 2024.
Abstract The wind energy market is currently dominated by horizontal axis wind turbines (HAWTs); however, vertical axis wind turbines (VAWTs) are emerging as a design alternative, especially for deep‐water offshore siting due to their low center of gravity, ease of access to drivetrain components, and overall simplicity.

Water‐Ice Dominated Spectra of Saturn's Rings and Small Moons From JWST

Journal of Geophysical Research: Planets, Volume 129, Issue 3, March 2024.
Abstract JWST measured the infrared spectra of Saturn's rings and several of its small moons (Epimetheus, Pandora, Telesto, and Pallene) as part of Guaranteed Time Observation program 1247. The NIRSpec instrument obtained near‐infrared spectra of the small moons between 0.6 and 5.3 microns, which are all dominated by water‐ice absorption bands.
