Expression of Ki-67, as a measure of cellular proliferation, has the benefit of enabling stromal cells to be ignored, which is more difficult in analysis of S phase with flow cytometry.
The identification and characterization of phosphatases that remove specific phosphorylated residues is inherently more difficult than analysis of kinase-mediated phosphorylation, and we expect that the number of sites associated with specific phosphatases will expand considerably with additional large-scale MS-based efforts in the near future.
Characterizing uncertainty through external as well as internal validation is important but more difficult for policy analysis models, because they involve conditional forecasts.
For these reasons, the interpretation of data obtained in the field is much more difficult than the analysis of laboratory results.
However, complex hexaploid wheat genomes makes high throughput SNP analysis more difficult and therefore more research is needed to identify the best platform for high throughput SNP analysis.
Also, in the case of immersion tests, the deposit to be expected often remains of very limited depth, making XRD analyses more difficult to perform (the analysis of thin deposits being more effectively carried out with glazing angle analyses); complementary analysis may then be required, including in particular spectroscopy techniques that are addressed below.
That will drag down nominal GDP in the short term, and make budget cuts more difficult to carry out.Our analysis may even be too optimistic.
Organically bound sulfur in the form of the natural isotope 33S can be directly examined by nuclear magnetic resonance (NMR) spectroscopy, although the low natural abundance (0.76 percent) and small magnetic and nuclear quadrupole moments make analysis more difficult than for protons (1H) or carbon-13 (13C).
However, impulsive actions can influence the behavior of solutions making the analysis more difficult.
The moiré pattern degrades the scanning result and makes document analysis more difficult.
