Abstract The physical meaning of the transcendental function in traditional thermally stimulated current (TSC) equation of electric dipoles with a single activation energy was first analyzed. Then a simple formula obtained directly from the tested TSC for calculating activation energy parameter, etc., was deduced. Numerical calculation showed that the exact TSC agrees with the approximated one very well. Further analysis found a limiting condition for the discrete to continuous activation energy density distribution and a criterion for discriminating the contributions to TSC by depolarization of the dipoles with multi-activation energy from those with a single one.

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.
