Abstract This paper studies the interactions between two and more adjacent chirped soliton-like pulses, respectively. The results show that the pulses present strong interactions when the separations between them are smaller than a certain value, and their behaviour is very distinct under different conditions, such as a different number of pulses or different initial separations between them. Furthermore, we also study the suppression of these interactions and obtain very good effects by using different initial amplitude ratios.

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.
