Ghost effect from Boltzmann theory

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 558-675, March 2026.
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Denoising Low‐Power CEST Imaging Using a Deep Learning Approach With a Dual‐Power Feature Preparation Strategy

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 3, Page 1410-1428, March 2026.
ABSTRACT Purpose: Low‐power (LP) chemical exchange saturation transfer (CEST) Z‐spectra have significantly reduced confounding effects and enhanced peak resolvability, thereby improving the observation and quantification of various CEST effects. However, LP Z‐spectra suffer greatly from reduced contrast‐to‐noise ratio (CNR).

Fast 3D UTE in vivo T1 and T2*$$ {\mathrm{T}}_2^{\ast } $$ mapping of fast relaxing knee tissues at 3 T

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 693-705, February 2026.
Abstract Purpose UTE MR imaging captures quantitative signals in fast‐relaxing tissues, enabling anatomical visualization and quantitative assessment of T1 and T2*$$ {\mathrm{T}}_2^{\ast } $$ relaxation times. However, the clinical application of quantitative UTE MRI is limited by long acquisition times.
