The classic view of metabolism as a collection of metabolic pathways is being questioned with the currently available possibility of studying whole networks. Novel ways of decomposing the network into modules and motifs that could be considered as the building blocks of a network are being suggested. In this work, we introduce a new definition of motif in the context of metabolic networks. Unli...

Rāga motifs are the main building blocks of the melodic structures in Indian art music. Therefore, the discovery and characterization of such motifs is fundamental for the computational analysis of this music. We propose an approach for discovering rāga motifs from audio music collections. First, we extract melodic patterns from a collection of 44 hours of audio comprising 160 recordings belong...

The problem of multiple global comparison in families of biological sequences has been wellstudied. Fewer algorithms have been developed for identifying local consensus patterns or motifs in biological sequence. These two important problems have di erent biological constraints and, consequently, di erent computational approaches. The di culty of nding the biologically meaningful motifs results ...

We present in this paper three algorithms. The first extracts repeated motifs from a weighted sequence. The motifs correspond to words which occur at least q times and with hamming distance e in a weighted sequence with probability ≥ 1/k each time, where k is a small constant. The second algorithm extracts common motifs from a set of N ≥ 2 weighted sequences with hamming distance e. In the seco...

In this paper we present three algorithms for the Motif Identification Problem in Biological Weighted Sequences. The first algorithm extracts repeated motifs from a biological weighted sequence. The motifs correspond to repetitive words which are approximately equal, under a Hamming distance, with probability of occurrence 1/k, where k is a small constant. The second algorithm extracts common m...

RÉSUMÉ. Les développements récents des techniques de géolocalisation ont généré de larges volumes de données associées aux objets mobiles. Une des tâches d’analyse de telles données reste à identifier les objets évoluant ensemble. Cette problématique peut être résolue par les motifs spatiotemporels et de nombreuses propositions ont été réalisées ces dernières années. Néanmoins chacune de ces ap...

The aim of this study was to perform molecular and bioinformatics analysis of IGFBP2 gene promoter in association with some economic traits in indigenous Makuee (MS) and Lori-Bakhtiari (LB) breeds. DNA was extracted from blood samples of 120 MS and 200 LB and a 297 bp fragment from the upstream sequences of studied gene was amplified and genotyped by single-strand conformational polymo...
