do not include all of the articles in Applied Physics Letters when calculating Nature Index
Physical Review B (PRB) and Applied Physics Letters (APL) are large physics journals and have almost the same reputation. For PRB, only the articles classified as 'Rapid Communication' or 'Editors' Suggestions' are included by Nature Index. Why does Nature Index includes all of the articles in APL? Actually, A small number of articles in APL, which are featured as 'Editor's Picks' in the website of APL, have higher importance, more urgency or more interest for the community. It seems to be more reasonable for Nature Index to only include those articles in APL.
Thank you for your interest in the Nature Index, and thank you for your interesting suggestion. We will review it and assess the impact on article counts and the dataset.
