Notes. U(xmin;xmax): uniform distribution between xmin and xmax. J(xmin;xmax): Jeffreys (log-flat) distribution between xmin and xmax. N(μ;σ): normal distribution with mean μ and standard deviation σ. AN(μ;σ−;σ+): asymmetric normal distribution, with different widths at each side of mean value.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
