Moreover, it would not face the problems that constrain the accuracy of curved lenses and so could make a perfect lens.Unfortunately, the only material with a negative refractive index to be developed so far worked only at wavelengths very much longer than those of visible light.
Scale issues constrain the accuracy of retrieval and limit the development of remote sensing applications.
These azimuthal gap values are sufficient to constrain location accuracy for these events as the largest azimuthal gap is, at worst, 180° as also specified by several authors such as Engdahl et al. (1998, 2007).
Such verification results help us understand and constrain the accuracy and reliability of ash transport models and it is of enormous relevance for designing future operational mitigation strategies at Volcanic Ash Advisory Centers.
A possible limitation of both the NHANES and LIDPBC studies is the use of spot urine samples, which may constrain the accuracy of exposure assessment due to variable urinary dilution effects throughout the day [ 32].
Marker intersection between these maps is significant, but missing data, non-uniform data quality and anonymity of many markers constrain the accuracy of the map merging process and the resolution of synteny between barley and other genomes.
Finally, though the CFAS sample was population-representative in 1991, the age-specific prevalence of dementia is lower in 2011 [ 21] and so secular trends may constrain the accuracy of the delirium prevalence estimates.
On the concatenated alignment, we apply an adapted PETfold model that can handle fixed partial structures σp1 and σp2 from the first step by constrained expected accuracy scoring, which is an extension of PETfold's maximum expected accuracy scoring for constrained folding.
For sprays, as described by a kinetic disperse phase model strongly coupled to the Navier Stokes equations, the resolution strategy is constrained by accuracy objectives, robustness needs, and the computing architecture.
While hydrodynamic models can test hypotheses concerning the water balance of infrequent flood events, the scarcity of flow measurement data inhibits model calibration, constrains model accuracy and therefore utility.
