For spreading patterns that may arise from the azimuthal instability of a localised spot, the main effect of a Dirichlet boundary condition has been to limit the growth of the pattern.
For example, a strong initial barrier to gene flow in the first generation (F1) of secondary contact will slow the establishment and spread of fit recombinant genotypes that may arise in subsequent generations, whereas F1 heterosis may speed up this process.
A pandemic vaccine must be capable of inducing protection against hypothetical viruses that so far have not spread in the human population, but that may arise.
Metastases in breast cancer may arise through either lymphatic spread or through hematogenous dissemination.
The findings suggest that GBS isolates circulating in Brazil have a wide phenotypic and genotypic diversity and that macrolide-resistant isolates may arise by both clonal spread and independent acquisition of resistance genes.
These findings indicate that GBS isolates circulating in Brazil have a variety of phenotypic and genotypic characteristics, and suggest that macrolide-resistant isolates may arise by both clonal spread and independent acquisition of resistance genes.
Monroe H. Freedman, who teaches legal ethics at the Hofstra University School of Law in Hempstead, N.Y., agrees that problems may arise as the practice spreads.
The answer may arise out of the kind of disease spread that occurs ovarian cancer spreads intraperitoneally.
OTb represents an extrapulmonary form of tuberculosis and may arise either by haematogenous route or spread directly from the paranasal sinuses.
Mesenteric tumour deposition may arise by a number of different modes of spread as described earlier.
