The classification of the HRA was based on the definition created in the NHBS studies in 2006, namely, a small set of zip codes with both the highest prevalence of poverty and rates of heterosexual HIV [ 14, 15].
But it soon became clear that mice, though very similar to people at the genetic level, have a somewhat different set of ZIP codes, often using the same code but in different organs.
The analyses of a set of 178 HD-Zip I proteins allowed the identification of six groups, in most cases with high sequence conservation outside the HD and HALZ.
These codes would allow a dynamic analysis of those delivery patterns: If a specific post office delivered a certain volume of mail to its existing set of ZIP codes before "standard" deliveries ended, how many ZIP codes could it now add to maintain the same volume?
25 percent more time was taken to unzip and zip a set of files.
An in silico analysis was performed on a set of 178 sequences from HD-Zip I transcription factors from different species (Additional file 1).
Two levels of geographic aggregation were considered; the first aggregation combines the full set of zip codes in the San Diego County study area (county region) and the second merges zip codes into sub-regions (SRs; Figure 4).
Quasi-identifier attributes means a set of information, for example, gender, age, date of birth, zip code.
Demographic statistics for zip codes were amalgamated into counties (as a sum of zip codes) in order to better display national variations in a choropleth map.
