Quantitative susceptibility mapping in magnetically inhomogeneous tissues

Magnetic Resonance in Medicine, Volume 94, Issue 3, Page 1044-1059, September 2025.
Abstract Purpose Conventional quantitative susceptibility mapping (QSM) methods rely on simplified physical models that assume isotropic and homogeneous tissue properties, leading to artifacts and inaccuracies in biological tissues. This study aims to develop and evaluate DEEPOLE, a deep learning–based method that incorporates macroscopically ...

Complex non‐Markovian dynamics and the dual role of astrocytes in Alzheimer’s disease development and propagation

Quantitative Biology, Volume 13, Issue 3, September 2025.
Abstract Alzheimer’s disease (AD) is a common neurodegenerative disorder nowadays. Amyloid‐beta (Aβ) and tau proteins are among the main contributors to the AD progression. In AD, Aβ proteins clump together to form plaques and disrupt cell functions.

Machine Learning‐Based Denoising of Surface Solar Irradiance Simulated With Monte Carlo Ray Tracing

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Simulating radiative transfer in the atmosphere with Monte Carlo ray tracing provides realistic surface irradiance in cloud‐resolving models. However, Monte Carlo methods are computationally expensive because large sampling budgets are required to obtain sufficient convergence.

End‐to‐end frequency enhancement framework for GPR images using domain‐adaptive generative adversarial networks

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 22, Page 3466-3482, 9 September 2025.
Abstract Ground‐penetrating radar (GPR) offers nondestructive subsurface imaging but suffers from a trade‐off between frequency and penetration depth: High frequencies yield better resolution with limited depth, while low frequencies penetrate deeper with reduced detail.

Disentangling Radiative Versus Non‐Radiative Controls on Urban Evapotranspiration Under Global Warming

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract As the nexus of terrestrial water‐energy‐carbon exchange, evapotranspiration (ET) modulates ecosystem‐climate interactions, yet its biophysical responses to urbanization and climate change remain unclear. Using fully coupled Earth system modeling and flux tower observations, we disentangle radiative (surface available energy) and non‐radiative
