GRASS-NB: Group-structured variable selection for spatial negative binomial data with applications to cancer registry and spatial omics

Spatially structured, overdispersed count data with high-dimensional predictors are increasingly observed across studies from population-level epidemiology to cellular-level spatial omics. Feature selection is critical to identify influential predictors, such as key risk factors or biomarkers. Few Bayesian studies have assessed negative binomial regression (NBR) models with standard variable selection priors, like the mixture spike-and-slab (SS) […]

Carborane-NHS esters as versatile reagents for amine-selective small-molecule modification, bioconjugation, and peptide-polymer assembly

Carboranes – hydrophobic, boron-rich clusters with unique structural properties – offer broad potential in materials science and biomedicine. They can mimic carbocyclic frameworks for designing advanced materials such as polymers and MOFs, and when incorporated into biomolecules, reduce local polarity while enriching boron content: a feature attractive for boron neutron capture therapy (BNCT). Here, we […]

Exploring the Winner-Loser Effect on Emotion in Crickets

Individual variation in behavioral traits, commonly referred to as personality, is exhibited in numerous animal species, including invertebrates. The specific personality trait of exploration tendency may be affected by positive/optimistic or negative/pessimistic emotional states. Animal contests can induce these emotions, as winning against one’s opponent increases ‘optimism’, while losing causes ‘pessimism’; these states can then […]
