These numbers are frequently used in large-scale computational datasets:
The string appears to be a unique identifier or a specific coordinate pair found in technical and scientific datasets, most notably in genomic research and public housing financial data. 1. Genomic Mapping (Bacillus subtilis)
: Listed as a TDC limit for specific unit types (e.g., Walkup or Elevator buildings) in various geographic regions. 429535_475874
In molecular biology, these numbers refer to specific genomic locations in the Bacillus subtilis genome (specifically the NC_000964 reference sequence ):
: Marks the end boundary for the ydzA gene (locus tag BSU_04240), which encodes a putative protein. 2. HUD Total Development Cost (TDC) Limits In molecular biology, these numbers refer to specific
: Marks the end boundary for a "putative protein binding surface" or TPR repeat within the rapC gene.
: They are found in the Census.gov population estimates files, likely representing specific demographic counts or internal record IDs. : They are found in the Census
: Similarly represents a capped development cost for different unit configurations in high-cost areas. 3. Data Science & Benchmarking
