Weaknesses in controls on imports, as outlined above, provide an additional element of complexity.
This may possibly be an additional factor in explaining the enormous complexity of gene deregulation in the cancer transcriptome.
There is an additional factor at work.
To examine the potential effects of presentation time on our results, we next performed an ANOVA that included presentation time as an additional factor (three within-subject factors: contrast, featural complexity, and presentation time).
We could find only small effects because we only focussed on two of many relevant migrant groups and did not consider the complexity of migration processes, but our findings do show that migration is an additional factor influencing mortality trends.
Geography is an additional factor.
The economy is just an additional factor".
And an additional factor was at work.
Apparent discrepancies in the observed patterns may partly reflect clade-specific responses to underlying ecological factors, adding an additional level of complexity to interpretations of insular body size shifts [14].
Adding an additional layer of complexity, many angiogenic factors have immune-modulating properties; 24 therefore, we considered the role of angiogenesis proteins along with recognized immunoregulatory molecules.
The MAZ transcription factor activity (Table 1) adds an additional layer of complexity between influenza infection-induced apoptosis, immune cell trafficking, and the observed cell cycle arrest.
