Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Local self-interaction-free approximate exchange-correlation potentials are derived and applied in the Levy–Nagy variational density functional theory for individual excited states. The self-interaction-corrected (SIC) local von Barth–Hedin and Vosko–Wilk–Nusair potentials are studied for excited states of some atoms and ions. Accurate ionization energies and correct asymptotic decay of excited SIC potentials are observed. Approximate validity of Koopmans’ theorem for excited states are shown.
