File:Muller-Sieburg influence spread.jpg

English: The graphic shows the spread in the literature of Muller-Sieburg's concepts of stem cell heterogeneity, myeloid bias, lymphoid bias and balanced HSC differentiation behaviors starting from the year 2000 (black dot at center) up to the year 2023 (outer boundary). A: Seven major journal were used: Blood (Blue), Experimental Hematology (Orange), Cell Stem Cell (Red), Frontiers in Immunology (Green), Journal of Experimental Medicine (Cyan), Proceedings of the National Academy of Science (Brown), and Nature (Purple). Spread is depicted by mapping the number of publications per year for each journal onto the time spiral given by the parametric curve (\[Tau](t)cos(2\[Tau](t)),\[Tau](t)sin(2\[Tau](t)),0) for t\[Element][2000,2023] via (\[Tau](t)cos(2\[Tau](t)+f(\[Tau](t))),\[Tau](t)sin(2\[Tau](t)+f(\[Tau](t))),0). \[Tau](t) denotes the function which scales time in years to values in the interval [0,2\[Pi]] and f denotes the interpolation function transforming the number of citations in each journal for every year to the scale of values on the expanding time spiral. B: The same expansion graphic with PubMed citation spread (Black) included (shown are 3094 PubMed listed publications with approximately 301,000 cross references). All raw data were harvested from the Dimensions database (https://www.dimensions.ai/) using the key words "hematopoietic stem cell", "heterogeneity", "myeloid-biased", "lymphoid-biased" and the date parameters 2000 to 2023 [years]. All data were processed using a Wolfram Language program developed and applied to the data by Hans B Sieburg.
