Each strip is that field's whole ranked pool, with the notch where NEC (Germany) sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).

Which fields of science does NEC (Germany) work in?

In all years, 92% of research at NEC (Germany) is in Physical Sciences, 6% in Social Sciences. Its largest fields are Computer Science (62%), Engineering (25%), Social Sciences (3%). It does 2.2× the world's share of Physical Sciences.
