This map shows the geographic impact of Yusuke Sumiki's research. It shows the number of citations coming from papers published by authors working in each country. You can also color the map by specialization and compare the number of citations received by Yusuke Sumiki with the expected number of citations based on a country's size and research output (numbers larger than one mean the country cites Yusuke Sumiki more than expected).
This network shows the impact of papers produced by Yusuke Sumiki. Nodes represent research fields, and links connect fields that are likely to share authors. Colored nodes show fields that tend to cite the papers produced by Yusuke Sumiki. The network helps show where Yusuke Sumiki may publish in the future.
Co-authorship network of co-authors of Yusuke Sumiki
This figure shows the co-authorship network connecting the top 25 collaborators of Yusuke Sumiki.
A scholar is included among the top collaborators of Yusuke Sumiki based on the total number of

Rankless uses publication and citation data sourced from OpenAlex, an open and comprehensive
bibliographic database. While OpenAlex provides broad and valuable coverage of the global
research landscape, it—like all bibliographic datasets—has inherent limitations. These include
incomplete records, variations in author disambiguation, differences in journal indexing, and
delays in data updates. As a result, some metrics and network relationships displayed in
Rankless may not fully capture the entirety of a scholar's output or impact.
