In the original publication of this article, Eq. (20b) is incorrectly published due to the negligence of the author’s proofreading. The correct version of Eq. (20b) is provided below:

$$ A \cdot y\left( {v_{*} } \right) = \ln \left( {1 - \frac{l}{L}} \right) = \ln \left( {\frac{{l^{\prime } }}{L}} \right). $$
