Medical Physics, EarlyView.Abstract Background Proton therapy (PT) is a beneficial modality for treating certain cancers but remains under utilized due in part to the high cost of existing PT devices. Dielectric wall accelerators (DWAs) are a proposed class of coreless induction accelerators that may present a suitable option for compact and affordable PT.

Simulated radiation levels and patterns of MRI without a Faraday shielded room
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose We characterize electromagnetic (EM) radiation patterns and levels in conventional MRI systems as a function of field strength and load symmetry, providing a framework for mitigation strategies allowing operation without a shielded room. Methods We simulated the far‐field radiation pattern and fields at a 10 m radius (|E|10m and |B|10m)

Magnetic Resonance in Medicine, EarlyView.Abstract Purpose In MR electrical properties tomography (EPT), conductivity and permittivity are reconstructed from MR measurements. However, depending on the reconstruction method, reconstructed electrical properties (EPs) show large variability in vivo, reducing confidence in the reconstructed values for clinical application in practice.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...

Near Surface Geophysics, EarlyView.Abstract Extensive pumping, storm floods or sea‐level rise can lead to regional and local‐scale processes of saltwater intrusion into coastal aquifers. Particularly when exacerbated by the impacts of climate change, these processes can threaten freshwater resources and thus drinking water supplies and need to be prevented by investigation and ...

Near Surface Geophysics, EarlyView.Abstract A comprehensive multi‐method geophysical strategy is used to investigate two faults in the Northern Upper Rhine Graben. Combining industrial 3D seismic data with our own 2D P‐ and S‐wave seismic, electrical resistivity tomography (ERT) and ground‐penetrating radar (GPR), we created comprehensive subsurface images of the faults. 3D seismic data
