Fourier Shell Analysis: k‐Space‐Based Metrics for Assessing Super‐Resolution in 4D Flow MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To support the emerging field of super‐resolution (SR) in 4D flow MRI by proposing Fourier shell analysis to disentangle resolution enhancement from denoising effects during evaluation. Methods A thoracic aortic 4D flow MRI dataset was synthesized with various degrees of stenosis, providing ground truth flow fields generated using ...

Prospective Head Motion Correction in T1‐ and T2‐Weighted Long Echo Train Sequences Using Servo Navigation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To integrate MR‐based servo navigation in MPRAGE and 3D‐TSE sequences and demonstrate its potential for prospective head motion correction in structural imaging. Methods Repeated modules of servo navigators were inserted before each preparation pulse of MPRAGE and 3D‐TSE sequences (before‐prep) for rapid convergence of motion parameter

Anisotropic Diffuse Radiation Model of Photovoltaic Systems

Progress in Photovoltaics: Research and Applications, EarlyView.
Monthly incident diffuse energy—isotropic and anisotropic models. ABSTRACT The diffuse solar radiation is a component of the global solar radiation and may contribute a significant percentage (50% and above in some locations) of the electric output energy of Photovoltaic (PV) systems.

The Need for Fundamental Photovoltaics Research to Ensure Energy Security

Progress in Photovoltaics: Research and Applications, EarlyView.
The center of this graphic focuses on the core of this paper—that fundamental research is central to the continued development of the photovoltaic (PV) industry. To the left, we have depictions of what is being studied—PV materials, PV cell structures, and PV module structures.
