Notes.
See Lohr et al. (2014) for explanation of this ratio.
Obtained by extending the confirmed period change ratio (row 6/row 5) to all objects with plausibly-significant χ2 ratios (row 3).
Obtained by extending the detected wrong period ratio (row 8/row 5) to all objects with plausibly-significant χ2 ratios (row 3).
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.
