Abstract Based on the scaling rule: R(T, H, $\theta$) = R(T, h), where h = H(sin2$\theta$+cos2$\theta$/$\gamma$2)1/2 and $\theta$ is field angle with respect to the ab-plane, the scaling approach is performed to examine the c-axis resistances of single crystalline La1.86Sr0.14CuO4 as functions of field and its orientation at different temperatures. The anisotropy parameter $\gamma$ of the system is extracted from the scaling approach, but shows an unusual temperature-dependent behavior, which is not expected by conventional theory. A phenomenological explanation of this temperature dependence is presented.

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.
