The first point was tackled by a simulation study, calculating empirical levels of confidence intervals for regression parameters using different sample sizes.
A new study calculating intergenerational differences in human PCB exposure now suggests some of the highest exposures occurred well after the chemicals were phased out [ EHP 119 5):641 646; Quinn et al.].
To estimate and compare the degree of mutational robustness for the different FFL motifs, we carried out a numerical study calculating the frequency of functional shifts upon parametric perturbation of equation (6) as shown in figure 5.
The characteristics of the created topologies are revised in a static simulation study calculating the vertex connectivity and packet loss on node disconnections.
Vaccination is clearly far from 100% efficacious, with a recent large-scale 'sentinel' study calculating an overall VE of 47% [ 1].
Whilst a Canadian study calculated a prevalence rate of 44.7% [ 16] and a Finnish project [ 17] estimated 37.1%.
The ratio of gametocyte to asexual stages in P. falciparum was found to be less than 1∶10 [25]–[27], a recent study calculates a much lower ratio (1∶156) [28].
Gambling competition is cut-throat between the two banks of the Mississippi – and a recent study calculated that Illinois loses $550m a year in revenue to casinos in Missouri and other river states that allow smoking.
A case study calculated biodiversity scores for grassland along an intensity gradient, as well as those for winter wheat in the case of various cropping systems.
Improved diagnoses may contribute to the elevated number of cases, but a recent study calculates that better diagnosis does not explain a large part of the rise.
