The original PDF version of this Article contained an error in Table 1. On the right-hand side of the third row, the third equation was missing a β as an exponent on the first CB, and incorrectly read:

$$k_{\rm B}{{C}}_{{\rm B}} + r_{\rm p}{{C}}_{{\rm B}} = \frac{{\varepsilon \cdot {{\rm I}}}}{{\left( {1 - \varepsilon } \right)}}$$

The correct form of the equation is as follows:

$$k_{\rm B}{{C}}_{{\rm B}} \, ^{{\beta }} + r_{\rm p}{{C}}_{{\rm B}} = \frac{{\varepsilon \cdot {{\rm I}}}}{{\left( {1 - \varepsilon } \right)}}$$

This has now been corrected in the PDF version of the Article. The HTML version was correct from the time of publication.
