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
Recent experiments on SrRuO have indicated the presence of linear nodes in the superconducting order parameter. Among the possible spin triplet states, two-dimensional (2D) p-wave superconductivity with E symmetry appears to be inconsistent with the experiments, whereas the 2D f-wave order parameter with B ×E symmetry turns out to be a more likely candidate. Here it is shown how the quasiparticle bound-state wave functions around a single impurity provide a clear signature of the symmetry of the underlying superconducting order parameter.
