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.

Artifact Description
Imagine Kennedy Space Center in mothball status, weeds choking walkways, buildings crumbling back to nature, launch towers red with rust. Imagine what was once a critical mass of the world's finest space engineers and scientists now dispersed, their collective synergy lost forever. Imagine that they counted down to the millennium in 1999, launching it with fanfare and high hopes, but learned too late that the launch vehicle was flawed, an undetected self-destruct mechanism activating and slowly, yet inexorably, shutting down critical systems.This is not a science-fiction story, nor is it a doomsday prediction. It is, however, a tale about keeping the plant running, about trying to reduce the high cost of sending up rocket ships, about the nuts and bolts of enhancing our nation's space lift capability,
