Abstract The transition rate of a double well system driven by cross-correlated noises has been investigated, in when the correlation times between the noises are nonzero. From numerical computation, we find followings: (1) The transition rate decreases as the $\lambda$ ($\lambda$ is the strength of the correlations between noises) increases. (2) The transition rate increases as the $\tau$ ($\tau$ is the correlation time between noises) increases. It imglies that $\tau$ and $\lambda$ play opposite roles in the transition rate of the system (3). For the case of perfectly correlated noises ($\lambda$= 1), there is no the suppressed phenomenon in the double well system with cross-correlated noise sources.

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.
