Sequence comparison, a vital research tool in computational biology, is based on a simple O(n 2) algorithm that easily maps to a linear array of processors. This paper reviews and compares high-performance sequence analysis on general-purpose supercomputers and single-purpose, reconngurable, and programmable co-processors. The diiculty of comparing hardware from published performance gures is a...

A sequence family is a set of homologous sequences. Members of a sequence family diverge during evolution and share similarities, but similarities that span the entire family might be weak compared to similarities that span only few members of the family. When comparing any two members of the family the faint similarities that span the entire family are thus likely to be shadowed by the stronge...

Pairwise sequence alignments aim to decide whether two sequences are related and, if so, to exhibit their related domains. Recent works have pointed out that a significant number of true homologous sequences are missed when using classical comparison algorithms. This is the case when two homologous sequences share several little blocks of homology, too small to lead to a significant score. On t...

The fact that biological sequences can be represented as strings belonging to a finite alphabet (A, C, G, and T for DNA) plays an important role in connecting biology to computer science. String representation allows researchers to apply various string comparison techniques available in computer science. As a result, various applications have been developed that facilitate the task of sequence ...

in india, holstein and its crosses are being used extensively in breeding programmes and all these breeding bulls are screened for autosomal recessive genes. blood samples are collected in ethylenediaminetetraacetic acid (edta) coated tubes and dna was isolated by using phenol-chloroform method. polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) wereperformed by using...

Many recent studies have shown that glycosylation patterns of Agaricus bisporus are similar to those of mammalians, so that this organism is a good candidate for the expression of glycosylated pharmaceutical protein. To achieve constant interested gene expression in all cells of the organism, proper promoter isolation is necessary. To isolate this promoter, PCR with specific primers was perform...

Precedence constrained sequencing problem (PCSP) is related to locate the optimal sequence with the shortest traveling time among all feasible sequences. In PCSP, precedence relations determine sequence of traveling between any two nodes. Various methods and algorithms for effectively solving the PCSP have been suggested. In this paper we propose a cuckoo search algorithm (CSA) for effectively ...

Social Comparison is important as it can be either encouraging or discouraging for the person who makes it. Although studies concerning social comparison in the classroom context abound, few deal with the relationship between the role of social comparison orientation and tendencies in academic achievement in a competition based educational context. Adopting a non- experimental ex-post facto des...
