Connectomics has been using graph theory for a while, but this is cool. Seems like more algebraic topology methods will percolate in (hah!) over time.

Anyone have a link to actual paper? Without it there's nothing to be said or thought about this.

Thanks.

This method is computationally very intensive. Betti numbers are hard to estimate from data, statistically speaking.

Url changed from http://phys.org/news/2015-10-mathematical-method-reveals-neu..., which points to this.

Hey, have you noticed a pattern with phys.org links:

I wonder when it's time for an automated solution, or some submission UI to say, "Please don't submit this phys.org link, find the source it rips off and submit that."

Indeed we have, and it seems that you noticed us noticing it :)

This could be automated, but there are lower-hanging automation fruit we'll get to first.

Since most of the articles phys.org publishes are copies of university press releases, presumably they're not stealing, but the fact that they never link to the original, only the university's home page, seems questionable. More importantly, the reading experience is significantly worse and it's nicer to go to the original source in most cases.
