When people clap to music, sing, play a musical instrument, or dance, they engage in temporal entrainment. We examined the effect of music training on the precision of temporal entrainment in 57 children aged 10-14 years (31 musicians, 26 non-musicians). Performance was examined for two tasks: self-paced finger tapping (discrete movements) and circle drawing (continuous movements). For each tas...

Abstract There are a growing number of Information Communication Technology (ICT) applications in cultural heritage. However despite funding constraints, projects often involve similar or even duplicate work carried out at the same site. This emphasizes the need for an enterprise whose purpose is to coordinate research projects in this field. The EPOCH programme has been established to address ...

This paper introduces a novel method of speech epoch extraction using a modified Wigner-Ville distribution. The Wigner-Ville distribution is an efficient speech representation tool with which minute speech variations can be tracked precisely. In this paper, epoch detection/extraction using accurate energy tracking, noise robustness, and the efficient speech representation properties of a modifi...

EEG and EEG source-estimation are susceptible to electromyographic artifacts (EMG) generated by the cranial muscles. EMG can mask genuine effects or masquerade as a legitimate effect-even in low frequencies, such as alpha (8-13 Hz). Although regression-based correction has been used previously, only cursory attempts at validation exist, and the utility for source-localized data is unknown. To a...

An age replacement maintenance policy is considered here, in which a system is restored whenever it fails, or ages without failure up to a preventive maintenance epoch (whichever comes first). The duration of the restoration activity is random, and depends on whether it was precipitated by a failure or by a preventive maintenance action. The case where the preventive maintenance epoch is determ...

Fluconazole has been used as prophylaxis against systemic fungal infections in preterm neonates. We conducted a study to determine whether cessation of a policy of prophylactic fluconazole results in a resurgence of fungal infections in a unit. Neonates born in the 3 epoches: A 36-month pre-Fluconazole prophylaxis epoch (Group 1), a 21-month Fluconazole prophylaxis epoch (Group 2) and a 39-mont...

We investigate a spherical collapse model with and without the spatial curvature. We obtain the exact solutions of dynamical quantities such as the ratio of the scale factor to its value at the turnaround epoch (x ≡ a ata ) and the ratio of the overdensity radius to its value at the turnaround time (y ≡ R Rta ) with general cosmological parameters. The exact solutions of the overdensity at the ...

It is shown that the interaction of large amplitude electromagnetic waves with a hot electron-positron (e-p) plasma (a principal constituent of the universe in the MeV epoch) leads to a bunching of mass, energy, and angular momentum in stable, long-lived structures. Electromagnetism in the MeV epoch, then, could provide a possible route for seeding the observed large-scale structure of the univ...

A model unifying general relativity with quantum mechanics is further developed. It is based on a noncommutative geometry which supposedly modelled the universe in its pre-Planckian epoch. The geometry is totally nonlocal with no time and no space in their usual meaning. They emerge only in the transition process from the noncommutative epoch to the standard space-time physics. Observational as...
