Using a system similar to that in major Mexican airports, vehicles are stopped and inspected randomly before entering the United States -- a machine flashes a red light to indicate when a car is to be stopped.
Within our data sets >80% of analysed traces passed this quality control step and, as a matter of routine, we manually inspected randomly chosen subsets of valid and excluded traces to confirm appropriate categorisation and analysis.
To determine whether developing an algorithm to 'rescue' domain hits above the default reporting threshold of E-value 0.01 would uncover a significant number of additional annotations, we estimated the frequency of domain hits we would 'rescue' by manually inspecting randomly picked sets of sequences.
As mentioned earlier, cities historically have inspected either randomly or on the basis of prior inspection results.
The quality of libraries was inspected by randomly selecting and sequencing 276 clones.
To examine this possibility, we inspected 50 randomly chosen SNPs exhibiting zero FST from the full data set accepting any type of polymorphisms (i.e., minor allele count threshold n = 1) for each lake-stream system.
To further validate our method, we manually inspected a randomly selected 1% subset of the nucleotide strings and found that all were valid DNA sequences, implying that most extracted strings represent true DNA sequences.
Likewise, no gold-standard data exist that could be used to evaluate anatomical associations or event inference, so we manually inspected a randomly selected set of 100 extracted events for each component to estimate their levels of precision.
Boston was the first American city to randomly inspect bags on its subways.
The Department of Buildings does not randomly inspect residences, and mostly acts in response to complaints.
