A correction to the bandwidth difference method for assessment of magnetic resonance static field homogeneity

open access: yesMedical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Published guidance offers four methods of static field inhomogeneity (ΔB0)$( {\Delta {{B}_0}} )$ measurement, including a bandwidth difference method. However, an error exists in the implementation of this method, which we demonstrate analytically and experimentally.

Four Directions, One Solution: Enabling Rapid Diffusion Tensor MRI for Ultra‐Low Field Using Deep Learning

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1413-1426, September 2026.
ABSTRACT Purpose This study revisits the tetrahedral encoding strategy originally proposed to accelerate Diffusion Tensor Magnetic Resonance Imaging (DT‐MRI) by reducing the requisite number of diffusion‐weighted measurements to four. We examine its practical limitations and explore how artificial intelligence (AI) can extend its utility. Specifically,

Statistical Quantum Mpemba Effect From Griffiths Rare Regions

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 9, September 2026.
The statistical quantum Mpemba effect emerges robustly in disordered open quantum systems. Griffiths rare regions generate a hierarchy of relaxation times that simple extended Bloch states naturally probe, without requiring fine‐tuned initial states or detailed knowledge of the Liouvillian spectrum.

Origin and application of the Lorentz factor in X‐ray diffraction

open access: yesActa Crystallographica Section A, Volume 82, Issue 5, Page 350-360, September 2026.
This review treats the role of the Lorentz factor in quantitative analysis of X‐ray diffraction data. The origin of the Lorentz factor, its derivation and practical implementations for a variety of modern X‐ray diffraction methods are discussed.The Lorentz factor is a fundamental correction factor in quantitative analysis of X‐ray diffraction ...

Visual Components to Interpretation—Formal Approaches to Visible Meaning

open access: yesLanguage and Linguistics Compass, Volume 20, Issue 5, September/October 2026.
ABSTRACT Visual components of communication interact with the core linguistic system at all levels and make an important contribution to the meaning of the utterance expressed. This does not only apply to sign languages, which exclusively rely on the visual channel, but also co‐speech gestures and emojis, which are visual means that accompany and ...
