Their existence is no longer in question, but true to their history these cells, their origin, generation, and mechanisms of action have generated considerable controversy.
Already capacity-constrained as companies push to launch new satellites into low earth orbit, companies like Virgin Orbit, RocketLab, Relativity Space, ARCA, AstroSpace, Blue Origin, Generation Orbit, Lockheed Martin, Orbital ATK and others around the world have raised hundreds of millions to take payloads into space.
Heterogeneity may be due to pleoclonal origin, generation of phenotypic diversity within a clone, or spontaneous hybridization and chromosome loss.
We set the origin generation of the favored allele for each model to produce an average allele frequency of approximately 0.5, which met our goal of providing coverage for allele frequencies between 0.2 and 0.8.
Comparison of the genes associated with the putative FruMB DNA-binding motif versus all FruMB target genes again revealed the most significantly enriched GO term to be of neural origin, "generation of neurons" (GO 0048699; Figure 6D).
If t is a random variable, each origin generation-subpopulation must be weighted by its respective population size to reflect the probability that a new mutation originates in that generation [ 19].
As in this study the only three variables eligible for inclusion into a multivariable model (ethnic origin; ethnic origin & generation; immigration status) were nearly identical ('ethnic origin and ethnic origin & generation') or collinear ('immigration status' and 'ethnic origin'), a multivariable analysis was not feasible.
Several possible origins for generation of tensile stress include the following: interfacial stress between CoFe films and Cu-substrate, crystal texture and grain size, coalescence and stress evolution during film growth, and hydrogen adsorption/desorption.
A number of different mechanisms exist by which rotavirus strains can evolve, ranging from reassortment of single or multiple gene segments during mixed infections by strains of human-human origin or human-animal origin to generation of single point mutations in immunologically important genes.
Soap opera, like psychoanalysis, traces its origins, through generations of training and the passing on of wisdom, to a great founder, and Irna Phillips is that founder.
