1D Pre‐Acquisition Navigator Correcting Respiratory‐Induced Field Fluctuations in Multi‐Echo Gradient‐Echo Imaging of the Thoracic Spinal Cord

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In the spinal cord (SC), multi‐echo gradient echo (ME‐GRE) increases gray (GM) and white matter (WM) contrast and improves sensitivity to lesions in people with multiple sclerosis (pwMS). However, SC ME‐GRE is susceptible to breathing‐induced field fluctuations, causing ghosting artifacts and signal loss.

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

Magnetic 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 ...

Aiouea riedeliana comb. nov. (Lauraceae) from Brazil, with an amended description and provisional extinction threat assessment

Nordic Journal of Botany, EarlyView.
Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system

Oikos, EarlyView.
Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...
