Real‐time cardiac cine MRI: A comparison of a diffusion probabilistic model with alternative state‐of‐the‐art image reconstruction techniques for undersampled spiral acquisitions

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 4, Page 1731-1749, October 2025.
Abstract Purpose Electrocardiogram (ECG)‐gated cine imaging in breath‐hold enables high‐quality diagnostics in most patients but can be compromised by arrhythmia and inability to hold breath. Real‐time cardiac MRI offers faster and robust exams without these limitations.

Spectral Refraction Modeling of Waves Around the Steep Reef at Palau

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract Western Pacific islands, such as Palau, are susceptible to wave‐driven inundation due to low land elevations and limited space for coastal retreat. Assessing the impacts of extreme wave events on these low‐lying islands requires regional numerical models that account for remotely generated waves from all directions and that resolve the complex

LMARSpy: A GPU‐Ready Nonhydrostatic Dynamical Core With a Sharpness‐Preserving Monotonicity Limiter and a Conservative Vertical Implicit Solver

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract Global numerical modeling is advancing into the era of kilometer‐scale, non‐hydrostatic simulations, while heterogeneous computing emerges as a pivotal trend in high‐performance computing (HPC). As a strong candidate for next‐generation global kilometer‐scale general circulation models, the A‐grid dynamical core based on the Low Mach number ...

Advancing causal inference in ecology: Pathways for biodiversity change detection and attribution

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2276-2304, October 2025.
Abstract Understanding the causes of biodiversity change is essential for addressing environmental challenges. While causal attribution has advanced in other fields, ecologists remain cautious about causal claims or misinterpret predictive models as causal.
