results the mean age of patients was 60 ± 9.9 years. statistically significant relationship between the occurrence of af with mitral valve annulus, la volume index (lavi) , right ventricle function, and type of surgery (off pump or on pump) were detected in our study (p < 0.05) . there was no statistically significant relationship between the occurrence of af and time interval of p wave to a wa...

In this paper, we study the use of spectral patterns to represent the characteristics of the rhythm of an audio signal. A function representing the position of onsets over time is first extracted from the audio signal. From this function we compute at each time a vector which represents the characteristics of the local rhythm. Three feature sets are studied for this vector. They are derived fro...

In a production study, Bulgarian, English and German verses with regular poetic metrical metres of different types and elicited prose utterances with varied accentual patterns are produced in textual and iterative (dada) form and measured at syllable level according to the pairwise variability index (PVI) principle. Systematic differences in PVI values show that the measure is sensitive to metr...

Introduction: Recent reports have shown that rare fluctuations in cardiac cycles are &lsquo;forgotten&rsquo; quickly in healthy individuals and it is possible to quantify the &ldquo;memory length&rdquo; of a physiological time-series using an inverse statistical approach. Methods: In the present study, we assessed the effect of aging on memory length in cardiac rhythm. Results: There was a long...

THERE IS NOW A VIGOROUS debate over the evolutionary status of music. Some scholars argue that humans have been shaped by evolution to be musical, while others maintain that musical abilities have not been a target of natural selection but reflect an alternative use of more adaptive cognitive skills. One way to address this debate is to break music cognition into its underlying components and d...
