Each of the various electromechanical actuating materials discussed above (ferroelectric/piezoelectric ceramics, electroactive polymers, and conjugated conducting polymers) excel in some aspects, but may have unsatisfactory performance in other aspects.
This is an important issue because some of the high mobility materials discussed above exhibit non-idealities in their transfer and output characteristics, which make it difficult to apply standard mobility extraction methods.
The use of carbon-based materials, as discussed above, typically requires a surfactant to wrap each nanoparticle and inhibit aggregation due to van der Waals forces [25].
It should be noted that, in the period of interest, coating materials such as those discussed above were often mixed according to personal or local recipes, with a degree of experimentation.
It is often controversial what sort of entities these are - material objects, abstract types, processes, sets? - and so it is also controversial how far the arguments discussed above, which focus on material objects, are relevant to these special cases.
These 'consensus' predicted transcripts exhibited similar discrepancies to the RefSeq sequences as discussed above (refer to Supplementary Material for details).
In order to determine the extent to which source memory-related activity is dependent on material type, it is necessary to systematically compare source memory accuracy for different types of materials, such as the objects and scenes discussed above.
As discussed above, there is a genuine issue of material fact as to whether the NYT altered the meaning of the quotation.
However, the lognormals appearing in (15) and in the lognormal model discussed above have different origins and implications (supplementary materials S2.5.2).
