In the original publication, equation 8 was written as below:

$\sum {\vec{M}}_i=[I{]}_i{\vec{\alpha }}_i+{\vec{\omega }}_{\hspace{0.17em}}$

This was incorrect. It has been corrected to the below:

$\sum {\vec{M}}_i=\left[I{]}_i{\vec{\alpha }}_i+{\vec{\omega }}_i\times \right[I{]}_i{\vec{\omega }}_i$
