Abstract In this paper, analytic expressions of Gaussian curvature, Euler's characteristic and area of Schwarzschild surface for an accelerating particle are given. The effect of acceleration on the equatorial and polar circumferences is analyzed. The problem of embedding this surface into Euclidean 3-space is also examined.

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.
