The cluster network of co-authorships between all authors who contributed at least 5 articles to MJIRI and had at least one co-authorship with others. Out of 6046 MJIRI authors, 129 individuals had five or more articles, 73 of whom constructed the largest co-authorship network that are considered for the cluster mapping. This network contains 12 clusters and 164 co-authorships between 73 authors. The line thickness between two authors represents the number of co-authorships and the circle size represents the number of articles published by that author.
