Metric Options: Counts1 Year3 YearSelecting 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
Using 2.92 fb-1 of electron-positron annihilation data collected at s=3.773 GeV with the BESIII detector, we obtain the first measurements of the absolute branching fraction B(D+→KL0e+νe)=(4.481±0.027(stat)±0.103(sys))% and the CP asymmetry ACPD+→KL0e+νe=(-0.59±0.60(stat)±1.48(sys))%. From the D+→KL0e+νe differential decay rate distribution, the product of the hadronic form factor and the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element, f+K(0)|Vcs|, is determined to be 0.728±0.006(stat)±0.011(sys). Using |Vcs| from the SM constrained fit with the measured f+K(0)|Vcs|, f+K(0)=0.748±0.007(stat)±0.012(sys) is obtained, and utilizing the unquenched Lattice QCD (LQCD) calculation for f+K(0), |Vcs|=0.975±0.008(stat)±0.015(sys)±0.025(LQCD).
