Repeat or not repeat?—Statistical validation of tandem repeat prediction in genomic sequences [PDF]
Nucleic Acids Research, 2012 Tandem repeats (TRs) represent one of the most prevalent features of genomic sequences. Due to their abundance and functional significance, a plethora of detection tools has been devised over the last two decades. Despite the longstanding interest, TR detection is still not resolved. Our large-scale tests reveal that current detectors produce different,

To Repeat or Not to Repeat: Face-Ing the Facts [PDF]
, 1995 Auto-repeat is the automatic repetition of a function by continuous pressing of a button. In three separate tests, the design and operation of this auto-repeat feature for various electronical devices was examined. Eleven subjects took part in the experiment. Each subject was given the same stratgies for optimizing the auto-repeat feature.
