— In this paper we describe a novel approach to applying text-based information retrieval techniques to music collections. We represent tracks with a joint vocabulary consisting of both conventional words, drawn from social tags, and audio muswords, representing characteristics of automatically-identified regions of interest within the signal. We build(More)
In modern societies, cultural change seems ceaseless. The flux of fashion is especially obvious for popular music. While much has been written about the origin and evolution of pop, most claims about its history are anecdotal rather than scientific in nature. To rectify this, we investigate the US Billboard Hot 100 between 1960 and 2010. Using music(More)
A method for segmenting musical audio with a hierarchical timbre model is introduced. New evidence is presented to show that music segmentation can be recast as clustering of timbre features, and a new clustering algorithm is described. A prototype thumbnail-generating application is described and evaluated. Experimental results are given, including(More)
As proximal nerves are relatively spared in length-dependent, axonal polyneuropathy, we theorized that a sural/radial amplitude ratio (SRAR) might be a sensitive indicator of mild polyneuropathy. In this study, sural amplitudes and SRARs in patients with signs of mild axonal polyneuropathy were compared to those of normal, age-matched control subjects.(More)
BACKGROUND Several sources have attributed the vulnerability of the abducens nerve to its long intracranial course. However, other anatomic factors likely contribute to the apparent vulnerability of the abducens nerve to mass lesions and trauma. METHODS The authors performed a two-part anatomic study of the abducens nerve. In the first part of the study,(More)
Using a dataset of 7 billion recent submissions to the Last.fm Scrobble API 1 , we investigate possible popularity bias in Last.fm's recommendations and streaming radio services. In particular we compare the recent listening of users who listen regularly to Last.fm streaming services with those who listen less often or never. Finally we describe a new(More)
BACKGROUND The frequency of asthma varies between countries, and may also vary between ethnic groups in more geographically confined areas. We sought evidence of such ethnic variations in the UK for asthma frequency, morbidity, and health-services use, and to understand possible reasons for any differences. METHODS We searched MEDLINE, EMBASE, CINAHL,(More)
