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
Two main operating parameters (influent C/N ratio and electric current intensity) were examined for their impacts on the denitrifying bacterial community structure in an integrated system of three-dimensional biofilm-electrode reactor and sulfur autotrophic denitrification (3DBER-SAD). It was found that genus β-proteobacteria played a leading role under different operating conditions. The influent C/N ratio illustrated a great impact on denitrifying bacteria diversity. When the C/N ratio decreased from 1.07 to 0.36, the Shannon–Wiener index and Simpson index increased from 2.44 to 2.71 and from 0.89 to 0.92, respectively, while the proportion of heterotrophic denitrifying bacteria Thauera decreased from 61.4 to 21.1%, and the sulfur autotrophic denitrifying bacteria (e.g., genus Sulfuricella and Thiobacillus denitrificans) increased from 3.5 to 19.3%. In terms of the impact of electric current intensity, the Shannon–Wiener index and Simpson index decreased from 2.71 to 2.63 and from 0.92 to 0.90, respectively, as the current intensity increased from 60 to 400 mA.
