Melodic segmentation: structure, cognition, algorithms

open access: yesMusicologica Brunensia, 2017
Segmentation of melodies into smaller units (phrases, themes, motifs, etc.) is an important process in both music analysis and music cognition. Also, segmentation is a necessary preprocessing step for various tasks in music information retrieval. Several

Reversible DNA i-motif to hairpin switching induced by copper(II) cations [PDF]

open access: yes, 2015
i-Motif DNA structures have previously been utilised for many different nanotechnological applications, but all have used changes in pH to fold the DNA.

The C-terminal portion of the cleaved HT motif is necessary and sufficient to mediate export of proteins from the malaria parasite into its host cell [PDF]

open access: yes, 2012
The malaria parasite exports proteins across its plasma membrane and a surrounding parasitophorous vacuole membrane, into its host erythrocyte. Most exported proteins contain a Host Targeting motif (HT motif) that targets them for export. In the parasite

Mosar: Efficiently Characterizing Both Frequent and Rare Motifs in Large Graphs

open access: yesApplied Sciences, 2022
Due to high computational costs, exploring motif statistics (such as motif frequencies) of a large graph can be challenging. This is useful for understanding complex networks such as social and biological networks. To address this challenge, many methods

Gathering Existence as One of the Central Motifs in the Works of B. Pasternak and R.M. Rilke [PDF]

open access: yesStudia Litterarum
The article deals with the motivic paradigm of “collecting / packing existence” in the work of B. Pasternak. The study aims to determine its role in the lyrical and philosophical concept of the poet and to identify its structure and connection with the ...

Genome-Wide Identification of DNA Binding with One Finger (Dof) Gene Family in Tartary Buckwheat (Fagopyrum tataricum) and Analysis of Its Expression Pattern after Exogenous Hormone Stimulation

open access: yesBiology, 2022
DNA binding with one finger (Dof) proteins have been proven to be involved in multiple biological processes. However, genome-wide identification of the Dof gene family has not been reported for Tartary buckwheat (Fagopyrum tataricum).

MEMOFinder: combining _de_ _novo_ motif prediction methods with a database of known motifs [PDF]

open access: yes, 2008
*Background:* Methods for finding overrepresented sequence motifs are useful in several key areas of computational biology. They aim at detecting very weak signals responsible for biological processes requiring robust sequence identification like ...

Motif counting beyond five nodes [PDF]

open access: yes, 2018
Counting graphlets is a well-studied problem in graph mining and social network analysis. Recently, several papers explored very simple and natural algorithms based on Monte Carlo sampling of Markov Chains (MC), and reported encouraging results. We show,
