Reducing Variability in Deep Gray Matter QSM Using Differential ROI Referencing: A Phantom and In Vivo Evaluation

open access: yesNMR in Biomedicine, Volume 39, Issue 6, June 2026.
Differential ROI referencing in QSM reduces subject‐specific offsets and improves group‐discrimination sensitivity, enabling detection of PD‐related susceptibility differences (SN–PU). ABSTRACT Quantitative susceptibility mapping (QSM) measures the intrinsic magnetic susceptibility of tissues.

Exploring the Role of Vascular Factors and Tissue Properties in Pulsatile Brain Deformation

open access: yesNMR in Biomedicine, Volume 39, Issue 5, May 2026.
This study combined strain tensor imaging (STI), intrinsic magnetic resonance elastography (iMRE), and atlas‐based regional metrics to explore physiological drivers of cardiac‐induced brain strain. Volumetric strain was mainly associated with vascular factors such as cerebral blood volume and pulse pressure, whereas octahedral shear strain correlated ...

A Discontinuity-Guided Two-Dimensional Phase Unwrapping Method for SAR Interferograms

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Phase unwrapping (PU) is one of the core procedures of interferometric synthetic aperture radar. The traditional PU methods estimate the absolute phase gradient based on the assumption that phase is spatially continuous. However, this assumption is often

Three‐dimensional Antimony Sulfide Based Flat Optics

open access: yesAdvanced Functional Materials, Volume 36, Issue 32, 20 April 2026.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Holistic Retrieval of Absolute Coseismic Displacement Fields From Single Interferograms via Physics‐Aware GANs

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...
