Acoustic cues such as pitch height and timing are effective at communicating emotion in both music and speech. Numerous experiments altering musical passages have shown that higher and faster melodies generally sound "happier" than lower and slower melodies, findings consistent with corpus analyses of emotional speech. However, equivalent corpus analyses of(More)
The ability to merge two droplets is an important component of droplet-based lab-on-a-chip devices, yet flow-induced coalescence is difficult to achieve due to long film drainage times compared with relatively short residence times. We examine droplet collisions at a simple microfluidic T-junction and characterize the response for a wide range of droplet(More)
Although Cantonese lacks stress at the word level, rhythmic patterns are apparent at the sentence level. In order to develop an understanding of this phenomenon, we took a sentence and manipulated the syllabic content of several of its target words in order to observe the consequences for rhythmic structure. Overall, we found that sentence rhythms conformed(More)
The pi- flux from the biomedical channel at TRIUMF increases with increasing channel momentum, while the contaminating electron flux decreases. Since the electrons appear to result from conversion of the high energy gamma-rays produced by pi0 decay in the production target, the electron contamination can be reduced further by target configurations which(More)
