In computer science , the longest repeated substring problem is the problem of finding the longest substring of a string computer science string that occurs at least twice. This problem can be solved in linear time and space by building a suffix tree for the string, and finding the deepest internal node in the tree. The string spelled by the edges from the root to such a node is a longest repeated substring. The problem of finding the longest substring with at least math k math occurrences can be found by first preprocessing the tree to count the number of leaf descendants for each internal node, and then finding the deepest node with at least math k math descendants.

Unreferenced date December 2009 The recognition sequence , sometimes also referred to as recognition site , of any DNA binding domain DNA binding protein motif that exhibits binding specificity, refers to the DNAsequence or subset thereof , to which the domain is specific. Palindromic sequence Recognition sequences are palindromes . The transcription factor Sp1 biology Sp1 for example, binds the sequences 5 G T GGGCGG G A G A C T 3 , where G T indicates that the domain will bind a guanine or thymine at this position. The restriction endonuclease PstI recognizes, binds, and cleaves the sequence 5 CTGCAG 3 . However, a recognition sequence refers to a different aspect from that of recognition site . A given recognition sequence can occur one or more times, or not at all on a specific DNA fragment. A recognition site is specified by the position of the site. For example, there are two PstI recognition site in the following DNAsequence fragment, start at base 9 and 31 respectively. A recognition sequence is a specific sequence, usually very short less than 10 bases . Depending on the degree of specificity of the protein, a DNA binding protein can bind to more than one specific sequence. For PstI, which has a single sequence specificity, it is 5 CTGCAG 3 . It is always the same whether at the first recognition site or the second in the following example sequence. For Sp1, which has multiple 16 sequence specificity as shown above, the two recognition sites in the following example sequence fragment are at 18 and 32, and their respective recognition sequences are 5 GGGGCGGAGC 3 and 5 TGGGCGGAAC 3 . 5 AACGTTAG CTGCAG TC GGGGCGGAGC TAGG CTGCAG GAAT TGGGCGGAAC CT 3 See also DNA binding domain Transcription factor Classes , for more examples DEFAULTSORT Recognition Sequence Category Genetics Category Proteins Genetics stub ... more details

Balanced repeated replication is a statistics statistical technique for estimating the sampling error sampling variability of a statistic obtained by stratified sampling . Outline of the technique Select balanced half samples from the full sample. Calculate the statistic of interest for each half sample. Estimate the variance of the statistic on the basis of differences between the full sample and half sample values. Selection of half samples Simplified version Consider first an idealized situation, where each stratum of our sample contains only two units. Then each half sample will contain exactly one of these, so that the half samples share the stratification of the full sample. If there are s strata, we would ideally take all 2 sup s sup ways of choosing the half stratum but if s is large, this may be infeasible. If fewer half samples must be taken, they are selected so as to be balanced hence the name of the technique . Let H be a Hadamard matrix of size s , and choose one row per half sample. It doesn t matter which rows the important fact is that all the rows of H are orthogonal. Now, for each half sample, choose which unit to take from each stratum according to the sign of the corresponding entry in H that is, for half sample h , we choose the first unit from stratum k if H sub hk sub &minus 1 and the second unit if H sub hk sub 1. The orthogonality of rows of H ensures that our choices are uncorrelated between half samples. Realistic version Unfortunately, there may not be a Hadamard matrix of size s . In this case, we choose one of size slightly larger than s . Now the submatrix of H which defines our choices need no longer have exactly orthogonal rows, but if the size of H is only slightly larger than s the rows will be approximately orthogonal.
