We discuss branch points of a ne coverings and their e ects on Veech groups. In particular, this allows us to show that even if one polygon tiles another, the respective Veech groups are not necessarily commensurable. We also show that there is no universal bound on the number of Teichm uller disks passing through the same point of Teichm uller space and having incommensurable lattice Veech g...
In this survey paper, I describe three applications of tilings to music theory: the representation of tuning systems and chord relationships by lattices, modeling voice leading by tilings of n-dimensional space, and the classification of rhythmic tiling canons, which are essentially one-dimensional tilings.
The explosive growth of user data on the Internet has introduced significant security threats. In recent years, large data breaches and malicious content distribution (spam, malware) become prevalent. With the rapid adoption of mobile and wearable devices, user data now includes a wide range of personal mobile and physical data. It ranges from GPS location traces, to biometrics data, to user in...
This paper reports some findings from an interpretative study which investigated the impact of an Australian leadership development offshore course upon the conceptions held by a group of Chinese educational leaders. The findings revealed that most participants tended to develop more complex understandings of leadership throughout the course. The study identified a general shift from task/direc...
TO THE EDITOR—We thank Drs Wang and Liang for their comments. Mass drug administration (MDA) is not sustainable even in the short term and should not be advocated. Numerous epidemiological studies from around the world, dating back to the early 1980s, have shown that the impact of praziquantel on the prevalence, intensity, and morbidity of disease is short-lived and that in highly endemic areas...
Is Mandarin Chinese a syllable-timed language? Based on auditory impression, traditional analyses say it is. However, this question has rarely been investigated from the perspective of acoustic phonetics. Following Ramus et al. (1999) and Grabe and Low (2002), we measured the four rhythmic correlates: vowel percentage, consonant standard deviation, rPVI and nPVI in passage readings and conversa...

Let T be a tile made up of finitely many rectangles whose corners have rational coordinates and whose sides are parallel to the coordinate axes. This paper gives necessary and sufficient conditions for a square to be tilable by finitely many Qweighted tiles with the same shape as T , and necessary and sufficient conditions for a square to be tilable by finitely many Z-weighted tiles with the sa...
