Abstract Multiplicity fluctuation of the target residues emitted in the interactions in a wide range of projectile energies from 500 A MeV to 60 A GeV is investigated in the framework of two-dimensional scaled factorial moment methodology. The evidence of non-statistical multiplicity fluctuation is found in 16O—AgBr collisions at 60 A GeV, but not in 56Fe—AgBr collisions at 500 A MeV, 84Kr—AgBr collisions at 1.7 A GeV, 16O—AgBr collisions at 3.7 A GeV and 197Au—AgBr collisions at 10.7 A GeV.

Online attention
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.
