Percolation, the transition to extensive connectedness on gradual addition of links, was long believed to be continuous, but recent numerical evidence of 'explosive percolation' suggests that it might also be discontinuous if links compete for addition. Here we analyse the microscopic mechanisms underlying discontinuous percolation processes and reveal a strong impact of single-link additions. We show that in generic competitive percolation processes, including those showing explosive percolation, single links do not induce a discontinuous gap in the largest cluster size in the thermodynamic limit. Nevertheless, our results highlight that for large finite systems single links may still induce substantial gaps, because gap sizes scale weakly algebraically with system size. Several essentially macroscopic clusters coexist immediately before the transition, announcing discontinuous percolation. These results explain how single links may drastically change macroscopic connectivity in networks where links add competitively."],["dc.identifier.doi","10.1038/NPHYS1860"],["dc.identifier.isi","000287844300028"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/23723"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","1745-2473"],["dc.title","Impact of single links in competitive percolation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Musical rhythms are not entirely accurate and thus inevitably deviate from the ideal beat pattern. Nevertheless, computer generated perfect beat patterns are frequently devalued by listeners due to a perceived lack of human touch. Professional audio editing software therefore offers a humanizing feature which artificially generates rhythmic fluctuations. However, the built-in humanizing units are essentially random number generators producing only simple uncorrelated fluctuations. Here, for the first time, we establish long-range fluctuations as an inevitable natural companion of both simple and complex human rhythmic performances. Moreover, we demonstrate that listeners strongly prefer long-range correlated fluctuations in musical rhythms. Thus, the favorable fluctuation type for humanizing interbeat intervals coincides with the one generically inherent in human musical performances."],["dc.identifier.doi","10.1371/journal.pone.0026457"],["dc.identifier.isi","000296519600019"],["dc.identifier.pmid","22046289"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/8345"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/21739"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 2.5"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.5"],["dc.title","The Nature and Perception of Fluctuations in Human Musical Rhythms"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

African Trypanosomes, causative agents of fatal illness in humans and animals, use an insect vector (the Tsetse fly) to infect mammals, involving many developmental changes in which cell motility is of prime importance. Our studies reveal that differences in cell body shape are correlated with a diverse range of cell behaviors contributing to the directional motion of the cell. Straighter cells swim more directionally while cells that exhibit little net displacement appear to be more bent. Initiation of cell division, beginning with the emergence of a second flagellum at the base, correlates to directional persistence. Cell trajectory and rapid body fluctuation correlation analysis uncovers two characteristic relaxation times: a short relaxation time due to strong body distortions in the range of 20 to 80 ms and a longer time associated with the persistence in average swimming direction in the order of 15 seconds. Different motility modes, possibly resulting from varying body stiffness, could be of consequence for host invasion during distinct infective stages."],["dc.identifier.doi","10.1371/journal.pcbi.1002058"],["dc.identifier.fs","585661"],["dc.identifier.gro","3146199"],["dc.identifier.pmid","21698122"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/8012"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/3955"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","public"],["dc.relation.issn","1553-7358"],["dc.relation.orgunit","Fakultät für Physik"],["dc.rights","CC BY 2.5"],["dc.rights.uri","http://creativecommons.org/licenses/by/2.5/"],["dc.title","Impact of Microscopic Motility on the Swimming Behavior of Parasites: Straighter Trypanosomes are More Directional"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

In the Bohman-Frieze-Wormald model (BFW) of percolation, edges sampled from a random graph are considered individually and either added to the graph or rejected provided that the fraction of accepted edges is never smaller than a decreasing function with asymptotic value of alpha, a constant. The BFW process has been studied as a model system for investigating the underlying mechanisms leading to discontinuous phase transitions in percolation. Here we focus on the regime alpha is an element of [0.6,0.95] where it is known that only one giant component, denoted C-1, initially appears at the discontinuous phase transition. We show that at some point in the supercritical regime C-1 stops growing and eventually a second giant component, denoted C-2, emerges in a continuous percolation transition. The delay between the emergence of C-1 and C-2 and their asymptotic sizes both depend on the value of a and we establish by several techniques that there exists a bifurcation point alpha(c) = 0.763 +/- 0.002. For a. [0.6, ac), C-1 stops growing the instant it emerges and the delay between the emergence of C-1 and C-2 decreases with increasing alpha. For alpha is an element of (alpha(c), 0.95], in contrast, C-1 continues growing into the supercritical regime and the delay between the emergence of C-1 and C-2 increases with increasing alpha. As we show, alpha(c) marks the minimal delay possible between the emergence of C-1 and C-2 (i.e., the smallest edge density for which C-2 can exist). We also establish many features of the continuous percolation of C-2 including scaling exponents and relations."],["dc.identifier.doi","10.1103/PhysRevE.87.052130"],["dc.identifier.isi","000319393900001"],["dc.identifier.pmid","23767510"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/29864"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Amer Physical Soc"],["dc.relation.issn","1539-3755"],["dc.title","Phase transitions in supercritical explosive percolation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
