The sudden push now comes, in part, because of the practical advantages these few days in January offer.
(Measurement of high dissociation constants is difficult when one is measuring the depletion of the labeled species from solution, as was done in the cited studies, because of the practical limitations in the concentrations of PII that can be used in the experiments).
The use of carbon nanotubes, fullerenes and fullerene-like cages in electronic applications is limited because of the practical difficulties in creating electrode contacts to them.
While John & Easton's proposal of the usefulness of analyzing narrow bands is almost 19 years old, it did not gain much attention in the literature, probably because of the practical cost involved in doing the analysis.
Secondary measures were limited to Cluster B symptoms because of the practical difficulty patients in clinical practice can have linking a symptom (such as avoidance, numbing, hyperarousal, insomnia, or startling) specifically to a trauma as opposed to some other source, as required by the DSM-IV definitions.
