What is Dalian Naval Academy known for in research?

The fields where it stands highest, 2022–2025, ranked among every institution above the floor in each field.

Each strip is that field’s whole ranked pool, with the notch where Dalian Naval Academy 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 world mark, because the world rate differs by field (from about 6% to 21% in this record).

Which of those standings moved

The same fields on both windows: where it stood over the whole record, and where it stands in 2022–2025. The distance is the story, and it is the one thing the two rank columns above cannot show.
