In‐and‐Out: Algorithmic Diffusion for Sampling Convex Bodies

Random Structures &Algorithms, Volume 68, Issue 3, May 2026.
ABSTRACT We present a new random walk for uniformly sampling high‐dimensional convex bodies. It achieves state‐of‐the‐art runtime complexity with stronger guarantees on the output than previously known, namely in Rényi divergence (which implies TV, 𝒲2, KL, χ2$$ {\chi}^2 $$).

Insights Into the Antigenic Repertoire of Unclassified Synaptic Antibodies

Annals of Clinical and Translational Neurology, Volume 13, Issue 3, Page 547-561, March 2026.
ABSTRACT Objective We sought to characterize the sixth most common finding in our neuroimmunological laboratory practice (tissue assay‐observed unclassified neural antibodies [UNAs]), combining protein microarray and phage immunoprecipitation sequencing (PhIP‐Seq). Methods Patient specimens (258; 133 serums; 125 CSF) meeting UNA criteria were profiled;

Sialylation patterns in cerebral amyloid angiopathy

Brain Pathology, Volume 36, Issue 2, March 2026.
This study is the first to localize and evaluate sialylation modifications in the context of Alzheimer's Disease and Cerebral Amyloid Angiopathy, revealing a unique disease‐specific increase in intravascular sialylation. Abstract Glycosylation is the most common form of post‐translational modification in the brain and becomes significantly altered in ...

Efficacy and Safety of Rituximab Versus Inebilizumab in Patients With Neuromyelitis Optica Spectrum Disorder: A Dual‐Center, Real‐World Cohort Study

European Journal of Neurology, Volume 33, Issue 3, March 2026.
In our real‐world study of 276 patients, rituximab and inebilizumab demonstrated comparable efficacy in the medium term but differed in their safety profiles, with a significantly higher incidence of infusion‐related reactions observed in the rituximab group.
