Abstract The model of stochastic perturbation is built up systematically in quasi-ideal dispersion-managed soliton system, its influence on soliton propagation is investigated by both the variational approach and the numerical simulation, and it is found that the stochastic perturbation leads to disintegration of soliton and enhances the interaction between solitons. The nonlinear gain and filter are introduced to suppress effectively the influence on both soliton propagation and interaction.

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.
