Arthur first nominated his old political boss, Roscoe Conkling; he doubted that Conkling would accept, but felt obligated to offer a high office to his former patron.
We show that this dynamics leads to the coexistence of different strategies in oscillations, with obligate monogamy maintained at a high level.
Cats are obligate carnivores and require a high level of dietary protein to maintain nitrogen balance, compared to omnivorous and herbivorous species [ 1].
Although a direct inference of symbiotic lifestyle cannot be made by comparing the characteristics of these genomes to the CRt genome, it is interesting to note that CRt has a genome size similar to the obligate symbiont SCc, a coding content that is intermediate to the two obligate symbionts and a higher ratio of identifiable pseudogenes to protein-coding genes than any of them.
The AT mutational bias observed in obligate intracellular symbionts results in a high density of homopolymeric tracts of adenines or thymines in the genome, with some tracts as long as 12 bp.
We find that the constituents of non-obligate complexes possess a higher degree of structural disorder, more short linear motifs, and lower functional similarity compared to obligate interaction partners while SP and ME interactions are characterized by significant differences in network topology.
Among the obligate dwellers of subterranean waters (stygobionts), a high number belong to so-called thalassoid lineages, organisms that are derived directly from marine ancestors [ 7].
In response to arguments that the NYSE Euronext board is obligated to consider a higher proposal, the company has instead argued that its "merger of equals" agreement with Deutsche Borse does not set off legal requirements to consider a higher bid.
Instead, the Court of Appeals essentially reinstated an expansive 2001 decision by the original trial judge, Leland DeGrasse, that the state was constitutionally obligated to deliver the minimum of a high school education.
A debenture is a bond not secured by specific assets but accepted by investors because the firm has a high credit standing or obligates itself to follow policies that ensure a high rate of earnings.
