Localized Quadratic RF Encoded Spin‐Echo With Spiral‐PRIME Reconstruction: A Practical Alternative to 3D FSE for High‐Resolution Volumetric Brain MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To extend localized quadratic (LQ) RF encoded spin‐echo imaging with acquisition and reconstruction strategies that improve efficiency and artifact robustness, positioning it as a practical alternative to 3D FSE for high‐resolution volumetric brain MRI.

Toward Inter‐Sonication Monitoring of Skull and Brain Temperatures in Transcranial MRgFUS Using a 3D Stack‐of‐Spirals Sequence

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an MRI approach for simultaneous skull and brain temperature monitoring between sonications in transcranial MR‐guided focused ultrasound (MRgFUS) surgeries. Methods A 3D stack‐of‐spirals dual‐echo ultra‐short TE (UTE) sequence incorporating fat suppression, spiral deblurring, trajectory measurement, and B1 correction was ...

Servo Navigation and Phase Equalization Enhanced by Run‐Time Stabilization (PEERS) for 3D EPI Time Series

open access: yesMagnetic Resonance in Medicine, EarlyView.
Purpose To enhance time‐resolved segmented imaging by synergy of run‐time stabilization and retrospective data‐driven phase correction. Methods A segmented 3D EPI sequence for fMRI time series is equipped with servo navigation based on short orbital navigators and a linear perturbation model, enabling run‐time correction for rigid‐body motion, bulk ...

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

open access: yesOikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

Globalizing Comparative Public Administration With Integrative Contextualization: State Autonomy in the Developmental Path of Hong Kong and Singapore

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT The lack of a common variable for comparison has been a major obstacle to the development of Comparative Public Administration (CPA). State autonomy enables an integrative contextualization approach, allowing both the analysis of contextual individual country experiences and the generation of generalized comparable knowledge.
