Abstract By using the extended hyperbolic function approach, we consider a quintic discrete nonlinear Schr?dinger (QDNLS) equation and obtained new exact localized solutions ,including discrete bright soliton solution, dark soliton solution, alternating phase bright soliton solution and alternating phase dark soliton solution ,if a special constraint is imposed on coefficients of the equation.

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.
