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

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2660-2674, December 2026.
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, Volume 96, Issue 6, Page 2739-2754, December 2026.
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 ...

Tales of “Good Indian Hair”: Race, Value, and Sensory Contact Zones in Afro‐Asian Delhi

City &Society, Volume 38, Issue 3, December 2026.
ABSTRACT Hair, as a sociocultural bodily signifier, also becomes, once disembodied, a highly globalized and specialized commodity used for weaves, extensions, wigs and toupees around the globe. “Indian” hair is particularly valued in such commodity chains.

Synopsis of the Genera of Eucanthini Nikolajev, 2002 (Coleoptera: Geotrupidae), With Two New Genera From Australia and South America

Austral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Here, we review the generic classification of Eucanthini, resulting in the redefinition of Eucanthus Westwood, 1848 and erection of two new genera. Under this new framework, Eucanthus is restricted to six North American species, while two monotypic genera are described from the Southern Hemisphere: Antoniocanthus gen. nov.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

Agricultural and Forest Entomology, Volume 28, Issue 4, Page 636-647, November 2026.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...
