fun with 3D density visualizations :) top and middle panels show control vs. diseased EEG shape-feature distributions as nested overlays. bottom panel shows the pockets where the most pronounced shifts between groups are observed (blue: enriched in diseased group, green: depleted in diseased group).

what i find particularly enticing is the convexity and smoothness of the resulting non-parametric pockets of pronounced probability shift. these arise in a purely empirical fashion, in an unbiased way, from a comparison of the group-level distributions

the predictive performance corresponding to these pockets of pronounced probability shift remains to be seen, but in past studies we've done, such regions of interest indicate good quantitative outcomes... to be continued, i hope!

well, the nesting occurs as a result of the data :) the isosurfaces themselves are just overlays. but due to the biological nature of these distributions, you can expect this kind of nested structure, probably because of the non-discrete nature of electric field variations in the brain

This was an excellent exhibit. It’s here until January, and I believe there is a free day at PAM on Sunday—don’t miss it!

Just in time for Halloween, we've posted a new preprint on zombie deubiquitinases! As it turns out, standard #DUB catalytic mutants aren't truly dead - they've just become zombies that are still capable of removing noncanonical, ester-linked #ubiquitin signals...
