As predicted for a textbook 'cheat,' the presence of the ΔpvdD mutant reduced total population density: mixed cultures reached similar densities to pure ΔpvdD cultures (Figure 2c).
Findings confirm that higher population density, mixed land-use patterns, better accessibility to public transportation, and job-housing balance are important planning parameters that reduce household carbon emission in Beijing.
Industrial relocation and construction in the suburbs since the 1950s initially helped alleviate central city air pollution, although high population density and mixed industrial-residential land use continued to cause problems.
Specifically, employees working in locations of higher population density, greater mixed land use and higher road intersection densities have higher income.
On the contrary, central areas, characterized by higher population density, more mixed land use, greater road connectivity, and better access to workplaces or shopping areas, are associated with a smaller amount of electric bicycle ownerships [66].
More recently, the generation of a mixed population, depending on the cell densities, of central nervous system (CNS) neural progenitors and NC was also reported [17], [18].
The proportionality of infant death rate to the square of infant density is particularly suggestive because the probability that a disease spillover event amplifies throughout a population is closely related to the rate of contact between individuals, which in a well mixed population increases with the square of density [1].
A mixed population of P. redivivus with worm density of 10 000 worms/mL was incubated in 250 mL of S-complete medium supplemented with 3% HB101.
To our knowledge, no clear associations have been observed between CYP19A1 SNPs and mammographic density [ 45], and researchers in one study found no associations of oestrogen synthesis or oestrogen metabolism genes with mammographic density in a mixed population of perimenopausal, young postmenopausal and postmenopausal women [ 45].
In our case, we do not have well mixed populations, but explicit spatial contact networks given population density, technology diffusion and agent attributes.
Swarmer cells were isolated from mixed population cultures using a modified version of the percoll density centrifugation protocol [65].
