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
As a recently emerging wastewater treatment technology, Algal-bacterial granular sludge (ABGS) process shows significant advantages. However, current research on the ABGS system is a lack of a clear and complete understanding of the potential mechanism of signal molecules on the growth of ABGS. This study comprehensively explores the variations in the ABGS under different N-acyl-homoserine lactone (AHL)conditions by constructing three sequencing batch reactor (SBR) systems. The results indicate that N-hexanoyl-L-homoserine lactone (C6-HSL) accelerates the granulation process in the early stages by promoting the loosely bound extracellular polymeric substances (LB-EPS) secretion and filamentous bacteria growth, thereby shortening required time for initial granule formation. On the other hand, N-(3-oxodecanoyl)-L-homoserine lactone (3-oxo-C12-HSL) expedites the granulation process by promoting the tightly bound extracellular polymeric substances (TB-EPS) and aromatic protein secretion, benefiting structural stability and nitrogen and phosphorus removal efficiency of mature ABGS.
