Expert musicians introduce expression in their performances by manipulating sound properties such as timing, energy, pitch, and timbre. Here, we present a data driven computational approach to induce expressive performance rule models for note duration, onset, energy, and ornamentation transformations in jazz guitar music. We extract high-level features from a set of 16 commercial audio recordi...

background and objective: high-level gentamicin resistance (hlgr: mic ≥ 500 µg/ml) in enterococci is mediated by aminoglycoside modifying enzymes which is mainly encoded by aac(6′)-ie-aph(2′′)-ia gene. the aim of this study was to evaluate the frequency of   aac(6′)-ie-aph(2′′)-ia gene in clinical isolates of enterococcus facium and enterococcus faecalis collected from hospitals in northwest of...

Despite only a fraction of all organisms having evolved extravagant secondary sexual characters, these have played an important conceptual, theoretical and empirical role in evolutionary biology (Darwin, 1871; Cronin, 1991; Andersson, 1994). Secondary sexual characters such as the antlers of deer and the train of the blue peacock Pavo cristatus are presumed to have arisen and be maintained as a...
