We describe a computer program which is able to estimate the tempo and the times of musical beats in expressively performed music. The input data may be either digital audio or a symbolic representation of music such as MIDI. The data is processed off-line to detect the salient rhythmic events and the timing of these events is analysed to generate hypotheses of the tempo at various metrical lev...

Insufficient data on adolescent athletes is contributing to the challenges facing youth athletic development and accurate talent identification. The purpose of this study was to model the progression of male sub-elite swimmers’ performances during adolescence. The performances of 446 males (12–19 year olds) competing in seven individual events (50, 100, 200 m freestyle, 100 m backstroke, breast...

E-Companion of “Asset Pricing with Spatial Interaction” by Steven Kou, Xianhua Peng, and Haowen Zhong The E-Companion is organized as follows. Section EC.1 presents the mean-variance analysis with spatial interaction. Section EC.2 gives the proof of the S-CAPM theorem when there is a risk-free asset and when there is no risk free asset. The proof of the S-APT theorems is given in Section EC.3. ...

The fundamental premise of tagging systems is that regular users can successfully organize large collections for browsing and other tasks through the use of uncontrolled vocabularies. Until now, that premise has remained relatively unexamined. In this work, using library data as a guide, we look at whether tags do a good job of organizing large sets of objects. We find that tags are predominant...

Peng et al. (1) quantify aging and variation in the optical properties of black carbon (BC) particles representing ambient urban conditions in developed and developing countries. There are several key implications in the findings of Peng et al. Under polluted environments, rapid aging and highly enhanced absorption of BC particles (by a factor of 2.4 within a few hours) contribute importantly t...
