Abstract In this paper, we propose a dynamic mastering process model for signal waveform modulation (SWM) optical disc. To form the ideal microstructures and solve the problems in the SWM master manufacturing process, we use this model to simulate the three-dimensional mark profiles in the SWM read-only disc. The simulated micro-patterns of recording pits and lands are employed to optimize the writing strategy and provide a quantitative basis for manufacturing the sub-pits and sub-lands. The simulation mark profiles are compared with the experimental ones, which are produced with the optimized writing strategy parameters. Comparison results demonstrate that the simulated profiles are highly consistent with the actual ones.

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.
