CEST MRI data analysis using Kolmogorov‐Arnold network (KAN) and Lorentzian‐KAN (LKAN) models

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose To investigate the potential of using Kolmogorov‐Arnold Network (KAN) and propose Lorentzian‐KAN (LKAN) for CEST MRI data analysis (CEST‐KAN/CEST‐LKAN). Methods CEST MRI data acquired from 27 healthy volunteers at 3 T were used in this study.

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, EarlyView.
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.

Spatially‐explicit foraging by an apex predator linked to nearshore prey and their accessibility in lakes

open access: yesOikos, EarlyView.
Habitat coupling – where mobile predators forage over broad spatial scales and, in doing so, link food webs from semi‐discrete habitat patches – has emerged as a major structuring force in lake ecosystems. For the cold‐water apex predator lake trout Salvelinus namaycush, food‐web structure and morphometry‐driven accessibility to nearshore areas in ...

Relatedness, trait evolution, and climatic niche divergence in mammalian island endemics

open access: yesOikos, EarlyView.
Island mammals have influenced ecological and evolutionary theory since Darwin, and many of them provide textbook examples of the dramatic morphological evolution that often occurs in island communities. However, patterns of evolution in the climatic niches of island mammals have yet to be fully explored.
