For the first three decades following initial introduction in the 1820s, the spatial distribution of mugwort was randomly distributed (Figure 1d).
Under the null hypothesis of no spatial heterogeneity in the incidence rate of childhood acute leukaemia, the total number of observed cases was randomly distributed among the French areas according to a multinomial distribution with parameters proportional to the expected numbers of cases.
Males from S2 and S3 were manipulated and recorded a few days before the samples were used because these males did not participate directly in trials; however, the recording of samples was randomly distributed during the day after manipulation of males to provide similar distribution of the time between manipulation and recording (S2 5) or active participation of males (S1) in all groups of males.
Thirdly, a significant test was performed through the permutation test, and a reference distribution was generated under an assumption that the incidence was randomly distributed.
A significance assessment was performed by means of a permutation test, and a reference distribution was generated under the assumption that the prevalence was randomly distributed.
Polyvinyl alcohol (PVA) fiber, which adheres well to cement, was randomly distributed throughout the cemented sand.
The Fe/Mo active phase was randomly distributed among the layers of vermiculite.
Thus entrapped drug was randomly distributed in the interconnected nanostructures in the form of nanoscaled crystals.
A majority of cells contained one cluster, which was randomly distributed along the longitudinal axis of the cell under these stress conditions (Fig. 2b).
We found that although AA utilization was randomly distributed on the 16S phylogeny, FA and NA utilization were clustered (Supplementary Figure 6), implying that these two traits have a phylogenetic signal and some evolutionary process is limiting their selection.
Using spatial descriptive statistics it was found that the drug was randomly distributed after 24 h while the polymer bound dye remained in clusters.
