Erratum

n.b. The error described below was the result of a technical error, and thus was not the fault of the authors.

This article [1] contains an error characterised by a discrepancy in the presentation of equation (6) between the article’s HTML and PDF formats.

The version of the equation present in the HTML is correct, while conversely the version present in the PDF is incorrect.

As such, the correctly formatted equation is as follows:

$$ Q(t)=\left(\frac{e^{\lambda t}\cdot I}{\lambda }+{Q}_0\right)\cdot {e}^{-\lambda t} $$
