چکیده
HeteroGenome is a non-redundant catalog of DNA periodicity regions in a number of complete genomes of various organisms. It shows the results of an automated spectral-statistical approach to the genome-wide heterogeneity (latent periodicity) search. The significance level of revealed heterogeneities is 10 -6 and below. Heterogeneity regions listed in the database are potential regions of a latent periodicity indicated mainly by approximate tandem repeats. A specified Period Length, in which statistically significant heterogeneity has been determined, presents an estimation of periodicity pattern size. The Exponent shows the number of copies for this pattern in the revealed periodicity region. The average invariance for copies of the estimated periodicity pattern is characterized by a Preservation Level (ranging from 0.4 to 1.0) for the characters across period positions.

HeteroGenome: database of genome periodicity
We present the first release of the HeteroGenome database collecting latent periodicity regions in genomes. Tandem repeats and highly divergent tandem repeats along with the regions of a new type of periodicity, known as profile periodicity, have been collected for the genomes of Saccharomyces cerevisiae, Arabidopsis thaliana, Caenorhabditis elegans and Drosophila melanogaster. We obtained data...

In recent years, estimation of protein-coding regions in numerical deoxyribonucleic acid (DNA) sequences using signal processing tools has been a challenging issue in bioinformatics, owing to their 3-base periodicity. Several digital signal processing (DSP) tools have been applied in order to Identify the task and concentrated on assigning numerical values to the symbolic DNA sequence, then app...

The database model presented in this paper is suitable for application in which queries may require non-crisp references to certain attributes. The data item (attribute) values may be crisp or fuzzy. For instance, such adjectives as 'high' or 'normal' may be attribute values for the attribute blood pressure. A disease or a condition can be described by a number of symptoms which may be crisp al...
