Abstract The effect of dust charging and influence of its fluctuation on dust-acoustic shock waves in the sheath region of the dusty plasma is investigated. By employing the reductive perturbation technique, the Burgers' equation is derived. The weak shock wave solution is obtained and discussed in this dust-charge-fluctuation system.

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.
