A rank is drawn as its standing: the longer the bar, the nearer the top. Anything else is drawn against the larger of the two, and two values a hair apart are called level. Quality, citation excellence and the top-10% rate are explained in the methodology.

Who leads in each field?

Aalto University stands higher in 10 of 17 fields, RIKEN in 7. Aalto University leads most in Environmental Science (#348 against #802); RIKEN leads most in Agricultural and Biological Sciences (#331 against #718). Each bar is that side's standing among all institutions ranked in the field: the full bar is first place.

Size is fractional works in the topics tagged with each word; colour is the word's share of the side's work against its share of the world's. Each word links to the topic it comes from most.

How has their output grown?

Aalto University has out-published RIKEN every year since 2011, when it overtook it.
