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
The accuracy of one particular flavor of density functional theory (DFT) for polymers, a random walk version of the CMS-DFT for homopolymers, was evaluated. In the CMS-DFT, the polymers were modeled as chains of spherical interaction sites interacting with either hard core or Lennard-Jones potentials. It was observed that even without the empirical corrections, the density profiles predicted by RWCMS-DFT with self-consistent PRISM/MC theory input were in reasonable agreement with simulation. It was suggested that RWCMS-DFT being investigated has the advantage of to be fast, solvable in three dimensions, and requires no equation of state information.
