These temporal groups made intuitive sense for the Metro study setting and the operating hours of the system.
To reflect the temporal trends in crime, crime counts are stratified into three temporal groups: peak hours, off-peak day hours, and off-peak night hours.
As outlined previously, the hotspots identified by the two methods are compared by matching their physical locations for all four temporal groups.
The notions of the time geography framework in this study are used to stratify crimes at rail to different daily and hourly temporal groups dictated by the daily and hourly rhythms of human activities.
In this study, the fluence two-point correlation function was calculated across the four energy channels for each of the two temporal groups; the purpose being to investigate whether the fluence correlations are distinct for long and short bursts.
As an analysis in macroscopic level, the variations of truck type distribution for two temporal groups were statistically tested: (1) month-to-month variations and (2) season-to-season variations in which the months of November to March representing severe winter conditions are grouped into winter and the remaining months are grouped into non-winter.
Based on the literature, to reach a comprehensive statistical conclusion on whether truck type distribution is affected by two temporal groups and two weather factors, a Chi-squared test combined with a binomial test designed in this study as statistical validation procedure was applied.
This analysis revealed that certain significant pathways identified were unique to the gene expressions comprising only one of the three major temporal groups.
Another more focused method of analysis was performed on the gene expression data of the three major temporal groups (increased, variable, and decreased expression).
More similarities exist with our results of significant biological pathways identified (from KEGG and GenMAPP databases) for each of the three major temporal groups (Table 1) when compared to pathways identified (by KEGG database) for the three major temporal groups in Bais et al.[20].[20]
For all three of the major temporal groups and therefore during all time points of intramembranous bone regeneration following marrow ablation, certain biological processes comprise large percentages out of the total biological functions identified.
