Music notation software as a means to facilitate the study of singing musical scores
2013
Introduction. Learning to read music is a complex task which becomes more difficult if it involves students who have different levels of music knowledge. The cognitive load theory maintains that acquiring new knowledge or the development of new abilities imposes a cognitive effort which depends on: a) instructional design; b) complexity of the task and c) previous knowledge. Method. In the present study eleven students varying in previous musical studies participated in a comparative assessment of music reading exercises using two different kinds of help: usual music instrument and music notation software. Load Cognitive Theory was used as a conceptual framework to determine which interface…
Searches for violation of lepton flavour and baryon number in tau lepton decays at LHCb
2013
Searches for the lepton flavour violating decay tau(-) -> mu(-)mu(+)mu(-) and the lepton flavour and baryon number violating decays tau(-) -> (p) over bar mu(+)mu(-) and tau(-) -> p mu(-)mu(-) have been carried out using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb(-1), taken by the LHCb experiment at root s = 7 TeV. No evidence has been found for any signal, and limits have been set at 90% confidence level on the branching fractions: B(tau(-) -> mu(-)mu(+)mu(-) mu(+)mu(-)) p mu(-)mu(-)) (p) over bar mu(+)mu(-) and tau(-) -> p mu(-)mu(-) decay modes represent the first direct experimental limits on these channels.
