Ion current losses in the convolute and inner magnetically insulated transmission line of the Z machine

Physical Review Accelerators and Beams, 2019
We introduce a 1D planar static model to elucidate the underlying mechanism of large ion current losses in the vacuum convolute and the inner magnetically insulated transmission line (MITL) of the Z machine. We consider E×B electron flow, parallel to the

Synchronous Power Control of Grid-Connected Power Converters under Asymmetrical Grid Fault

Energies, 2017
Control of grid-connected power converters is continuously developing to meet the grid codes, according to which the generation units should keep connected to the grid and further provide ancillary services, such as voltage and frequency support ...

Electrothermal Oxidation of Ethylene Glycol Over Co3O4

Angewandte Chemie International Edition, Volume 65, Issue 32, 3 August 2026.
Pressurized electrothermal oxidation of ethylene glycol enhances catalytic performance toward glycolate under mild conditions. Higher reaction rates occur at 70–90°C and 15 bar O2, and potential and O2 pressure re‐oxidize Co2+ to Co3+ at the surface.

A Comparative dose and image quality assessment of a portable, multi‐modality extremity imaging system for austere environments

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Rapid technological innovation in diagnostic imaging requires timely, evidence‐based safety and quality assessment to ensure optimal patient care. This study evaluates a novel multi‐modality extremity imaging system (OXOS MC2) designed for deployment in remote and austere environments.

A physics primer on photon‐counting detectors in CT: Physics, signal formation, and performance

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Photon‐counting detector CT (PCD‐CT) is moving from laboratory development to clinical deployment. However, its threshold‐bin data arise from a tightly coupled detector–readout chain that can be difficult to understand as a whole. These data are not a direct readout of photon energy, but the outcome of a sequence of physical and electronic ...
