A system of symmetrically coupled identical oscillators with phase lag is presented, which is capable of generating a large repertoire of transient (metastable) "chimera" states in which synchronization and desynchronization coexist. The oscillators are organized into communities, such that each oscillator is connected to all its peers in the same community and to a subset of the oscillators in...

KDD (Knowledge Discovery in Data Bases) is multi-step process. KDD is the process that navigation to knowledge from the data base according to user requirements. This paper mainly explains the concept of three phase iterative model of KDD. It elaborates the traditional process of KDD and also explains the various limitations in that process. This paper also explained the process of three phase ...

Zero-lag phase synchronization of EEG activity has been reported to be a central mechanism accompanying long-term memory formation. In this pilot study, we examined the effects of synchronous low-amplitude stimulation of the rhinal cortex and the hippocampus in eleven temporal lobe epilepsy patients. The impact of in-phase stimulation (zero lag) on long-term memory encoding of words was contras...

Introduction: Direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. We compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (LFP) and LFPspike signals, respectively. Methods: Signals recorded from MT area of a macaque’s brain was used in a simulation ...

From near-infrared, narrow-band photometry of 256 oxygen-rich Mira variables we obtain evidence about the loops that these stars follow in colour–colour diagrams.We also find a phase lag between indices related to molecular band-strength of titanium oxide and vanadium oxide. We compute colours for normal M–giants and Miras using hydrostatic and hydrodynamic model atmospheres and very extensive ...

Our algorithm is based on autocorrelation. What distinguishes it from other autocorrelation approaches is that we computes the distribution of lag autocorrelation energy as a function of phase. This results in a lag-by-phase matrix that compactly represents the repetitive structure of a musical example. The model is designed to allow meter analysis of audio files. However it can also be used to...
