Abstract Transition in regular K-regime of boundary layer is studied. The features of the long streak that is considered as a form of soliton/like coherent structure (CS-soliton) are investigated briefly. The experiment shows that the breakdown of long streak is generated by chain of ring-like vortices.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
