Republican legislators stay away from the capitol to prevent the General Assembly from attaining the quorum needed for the body to act.
He issued secret instructions to Republican legislators, asking them to stay away from the capitol to prevent the General Assembly from attaining the quorum needed for the body to pass any legislation.
"In this way, a number of ants can build up a new nest site and if that number exceeds a threshold, which we call the quorum threshold, they'll switch from tandem running, which is excruciatingly slow, to picking up their nest mates and carrying them," says Franks.
The bill also does not touch the quorum threshold for the Export-Import Bank.
Democrats are looking to lower the quorum threshold and therefore allow the Ex-Im Bank to once again make loans above $10 million.
Keeping the costs mC, mS, mR and the cooperation reward r constant, we have systematically screened the effects of the quorum threshold nq and the diffusion parameter D on the evolution of cooperation and quorum sensing (Fig. 3, left column).
This results in an amplificatory process leading to faster population growth in higher quality sites, in which the quorum threshold is reached earlier than in lower quality sites.
It may occur at a large scale when the gene for cooperation is (almost) fixed in the population, due to a favorable benefit/cost ratio of the cooperative behavior and the quorum threshold relatively high.
It may increase the fitness of a bacterium, provided there are at least nq bacteria (possibly, but not necessarily, including itself) expressing the C allele as well within its 3×3-cell neighbourhood; nq is the quorum threshold of cooperation.
However, although the number of workers present in the nest at the onset of emigration was strongly correlated with the quorum threshold, we did not find any evidence that it had an influence on assessment time.
With the quorum threshold fixed at nq = 3 and diffusion at D = 0.0, we looked for the critical value of the fitness reward by increasing r from 0.5 to 0.9, and found it to be rc = 0.8.
