Universal productivity patterns in research careers

A common expectation is that career productivity peaks rather early and then gradually declines with seniority. But whether this holds true is still an open question. Here we investigate the productivity trajectories of almost 8500 scientists from over 50 disciplines using methods from time-series …

Data visualization with d3.js

According to Crameri et al., “The accurate representation of data is essential in science communication” [1]. Indeed, the choice of the most adequate type of visualization according to the characteristics of data is crucial in order to convey the results of scientific research. For example, the figure below shows the temporal evolution of the effective reproductive number $R(t)$ of COVID-19 in Maringá.
