Metric Options: Counts1 Year3 YearSelecting 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
The chemical steps needed to prepare specimens for "absolute" atomic-weight [(mean) relative atomic mass] determinations are outlined and discussed in detail for the atomic weight of silicon, A (Si), as recently measured for a redetermination of the Avogadro constant. The estimated combined uncertainties arising from the chemical procedures in that A (Si) measurement are shown to be almost equal to those from the associated mass-spectrometric measurements.
