Modeling the cofactor as a condition which spreads as a direct rate, instead of a density-dependant contact rate, would allow the model to take into account cofactors such as malnutrition or genetic variability, for example.
"If policy-makers wish to continue to support the availability of long-term, fixed-rate mortgages, they should consider doing so directly (e.g., perhaps through a direct, subsidized rate swap facility sponsored by the Fed)." But it's also not obvious that losing the 30-year fixed-rate mortgage would actually have a significant impact on home affordability or accessibility.
Over all, the county has about 28 million square feet of office space, 15 million of that Class A with a direct vacancy rate of 21 percent, Mr. Donnelly said.
The data in Fig 2 suggest that a direct killing rate of 0.63 would typically produce a decline substantially greater than 13%.
However, if a direct growth-rate dependent feedback significantly contributes to the regulation of gene expression, it would lead to an apparent correlation between expression levels and growth rates when a large number of unrelated mutants are examined.
We also used a direct mutation rate estimate from mutation accumulation lineages of Drosophila melanogaster by Haag-Liautard et al. [ 26].
By contrast, the four-patch cofactor model makes use of a direct transmission rate (βD = β, Figure 1b) from which any effect of the cofactor has been removed.
Under 5 10 CPD, the L C model describes a direct delivery rate effect, with increasing strength of association with increasing CPD; however, pack-year ranges are necessarily limited and effects are estimated with substantial uncertainty, and additional analyses are needed.
The results on treatment preferences demonstrate that the combined use of a direct assessment for rating different levels of importance on one hand and a collection of data by a DCE on the other is reasonable and effective.
A directed patrol rate implies that the patrols were implemented consistently throughout the response span.
Mr. Romney and his wife, Ann, paid a direct federal tax rate of about 14 percent over the past two years (with only modest variation between the 2010 and 2011 rates) on average annual income of $21 million, according to the returns released Tuesday.
