Repeat expansion mutations pose specific database issues [Martindale et al., 2012] and all pathological expansions of the noncoding G4C2 repeat in the C9orf72 promoter leading to FTLD and amyotrophic lateral sclerosis (ALS) are considered the same mutation.
In the experiments, we first utilized the Pointing'04 head-pose database, which comprises 15 sets of images.
Three face databases were tested: Yale database, Olivetti Research Laboratory (ORL) database, and the PIE (pose, illumination, and expression) database from CMU [24].
However, retrospective databases pose a series of methodological challenges, some of which are unique to this data source.
Finally, large registry databases pose other challenges.
Small discrepancies between directly amplified sequences and reference sequences in public databases pose difficulties for the definition of taxon boundaries, and complicate clinical interpretation of laboratory data (25, 26 ).
It is now easy to generate genome-wide scans with more than one million SNPs (single nucleotide polymorphisms) but these huge databases pose challenges in computational capacity, data analysis and interpretation of results for genomic selection [ 2].
Indexing of the nr database poses specific challenges as compared with other databases because nr is so large and is updated daily.
Simulations results with the Pointing Head Pose Image Database illustrate the performance of the designed correlation filter for multi-view face recognition.
What benefits and dangers do the use of these database applications pose to the Internet public?
To bolster its position that the new National Center for Education Statistics student database would pose no threat to student privacy, a Department of Education document cited in "A Federal Proposal to Keep Data on All College Students Raises Questions of Privacy" insists that data would not be shared with other agencies and that, by law, "information about individuals may NEVER leave N.C.E.S".
