The Diagnostic Value of Contrast‐Enhanced Vessel Wall MRI for Diagnosing Neuropsychiatric Systemic Lupus Erythematosus

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Imaging biomarkers for neuropsychiatric systemic lupus erythematosus (NPSLE) are highly needed, and intracranial contrast‐enhanced vessel wall imaging (CE‐VWI) can potentially detect cerebral vessel wall abnormalities in lupus. Purpose To evaluate the diagnostic value of CE‐VWI in differentiating NPSLE from non‐NPSLE.

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

Journal of Quaternary Science, EarlyView.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Discrete Chiral Ballistic Polariton Laser

Laser &Photonics Reviews, EarlyView.
Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.
