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

open access: yesMagnetic 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 ...

Anisotropic Diffuse Radiation Model of Photovoltaic Systems

open access: yesProgress 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

open access: yesProgress 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.

Near‐resonant excitation of the Adriatic barotropic modes: The seiche events of December 2019

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study examines severe flooding in the northern Adriatic Sea in December 2019, which existing forecasting systems failed to predict. Analysis of wind and sea‐level data, alongside reanalysis datasets and a high‐resolution hydrodynamic model, revealed a wind‐induced resonance mechanism.

Hybrid physics–data‐driven modeling for sea ice thermodynamics and transfer learning

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Icepack–NN, a machine‐learning‐based hybrid version of the sea‐ice column model Icepack, is developed to correct state‐dependent forecast errors arising from misspecified snow thermodynamics, using neural networks applied online within the physical model.
