The most cited paper in Japanese papers in the "Heisei" era is the paper "MEGA1: Molecular Evolutionary Genetics" on the development of bioinformatics tools (molecular evolutionary genetics: MEGA) by Professor Koichiro Tamura of Tokyo Metropolitan University. Analysis Using Maximum Likelihood, Evolutionary Distance, and Maximum Parsimony Methods ".This paper has been cited more than 5 times since its publication in 2011 (Heisei 23). The papers on the development of MEGA are also in the top 3 for the development of MEGA3, MEGA4, MEGA6, and MEGA7, which shows the great influence on the research.
The second place is "HELICAL MICROTUBULES OF GRAPHITIC CARBON" by Professor Sumio Iijima of Meijo University (NEC at the time of publication) on the discovery of carbon nanotubes. Cited more than 2 times since publication in 1991 (Heisei 3).The third place is the paper "Induction of pluripotent stem cells from mouse embryonic and adult fibroblast cultures by defined factors" by Professor Shinya Yamanaka of Kyoto University and others, and this paper won the Nobel Prize of Professor Yamanaka in 2. It was taken up as a reason.In the research on iPS cells by Professor Yamanaka et al., The paper "Induction of pluripotent stem cells from adult human fibroblasts by defined factors" on the production of human iPS cells in 9 (3) also ranked fourth.
About 30 million papers (papers included in the Web of Science Core Collection) have been published worldwide for about 3,000 years during the "Heisei" era.Of these, about 200 million papers (6.8%) involved Japan.The top 20 papers in Japan this time include not only papers on iPS cells that won the Nobel Prize, but also prominent achievements such as carbon nanotubes and perovskite solar cells, as well as papers on business administration related to knowledge management. rice field.In addition, as major changes in 30, the number of single authors decreased and the number of internationally co-authored papers increased sharply, reflecting the tendency of academic research in recent years.The 20 Japanese papers were in the top 0.001% of citations, and it can be considered that they had a great influence on the subsequent research.
