Most previous studies have been on nding full-cycle periodicity for all ...

UNLABELLED A web server for searching latent periodicity based on the method of modified profile analysis has been developed. This method allows searching latent periodicity in presence of insertions and deletions. During searching process, the periodicity classes are used which were found by us earlier for various groups of organisms. Period length belongs to the range 2-20 nt, not including t...

Summary. We analyzed several prokaryotic and eukaryotic genomes looking for the periodicity sequences availability and employing a new mathematical method. The method envisaged using the random position weight matrices and dynamic programming. Insertions and deletions were allowed inside periodicities, thus adding a novelty to the results we obtained. A periodicity length, one of the key period...

A new algorithm is presented for the detection and segmentation of multiple periodic motions in image sequences A periodicity measure which provides an accurate quantitative measure of sig nal periodicity in the form of temporal harmonic energy ratio is proposed The periodicity tem plates which incorporate the segmented region with the associated periodicity energy distribu tion and motion fund...

We identified latent periodicity in catalytic domains of approximately 85% of serine/threonine and tyrosine protein kinases. Similar results were obtained for other 22 protein domains. We also designed the method of noise decomposition, which is aimed to distinguish between different periodicity types of the same period length. The method is to be used in conjunction with the cyclic profile ali...
