However, the equation used by Duursma and Mäkelä ([2007]) was developed for a single k H and while the equation used by Forrester ([2014]) included a range of k H, it approached an asymptote and preliminary analyses showed that it could not provide adequate estimates of ϕ for some crown architectures and was occasionally not calculable for others due to its asymptotic form.
It was occasionally not clear which element of the AIM programme the comments and responses related to.
But my mistake is occasionally not knowing who somebody is.
The truth is, I'm not even sure what she's apologising for, except that I'm occasionally not that chatty.

However, due to the finite life-time and degradation of the GFP, parts of the cell were occasionally not visible at locations where substantial deformations were observed.
Since family members for our patients are not available to study, and mathematical inference is occasionally not conclusive, it was our goal to devise a novel, direct lab-based method to align marker alleles into haplotypes, using a nanofluidic approach.
