Detector alignment for X‐ray crystallography using Millepede‐II

Journal of Applied Crystallography, Volume 59, Issue 2, Page 594-608, April 2026.
A computational method for refinement of multi‐panel detector geometry has been adapted from high‐energy physics to serial crystallography. The method is many times faster and much more accurate than previous approaches.I describe a method for accurately refining the geometrical parameters of segmented X‐ray area detectors on the basis of serial ...

Linking Photophobia, Sleep Disturbances, and Migraine Chronicity: Evidence From a Retrospective Analysis

Brain and Behavior, Volume 16, Issue 3, March 2026.
This study demonstrated that ictal photophobia was present in 89.8% and interictal photophobia in 93.4% of patients. Sleep disturbances were common, with 44.9% reporting difficulty falling asleep. Network analysis revealed stronger associations between interictal photophobia, daytime sleepiness, and medication overuse in chronic migraine compared to ...
