The 'social complexity hypothesis' suggests that complex social structure is a driver of diversity in animal communication systems. Sperm whales have a hierarchically structured society in which the largest affiliative structures, the vocal clans, are marked on ocean-basin scales by culturally transmitted dialects of acoustic signals known as 'codas'. We examined variation in coda repertoires a...

BACKGROUND In order to understand how biological systems function it is necessary to determine the interactions and associations between proteins. Gene fusion prediction is one approach to detection of such functional relationships. Its use is however known to be problematic in higher eukaryotic genomes due to the presence of large homologous domain families. Here we introduce CODA (Co-Occurren...

This paper reports the acoustic experiment and perception test on a pair of Cantonese long and short vowels /a/ and /ɐ/ in the diphthong context. The acoustic data show that [aːi] and [ɐi] have similar targets of vowel nucleus and coda, parallel transition glide, and comparable total duration. They are different in their durational structure: [aːi] has a long steady phrase of vowel nucleus whi...

BACKGROUND phonological disorders. AIM to verify the occurrence of vocalic lengthening, through acoustic analysis, in a group of 16 children (8 boys and 8 girls) with evolutive phonological disorders (EPD), who did not present in their speech /R/ and /S/ medial codas; to verify the occurrence percentage of lengthening and omission strategies in the two types of coda. METHOD recordings of 16...

The aims of this study are (1) to determine the acoustic pattern signaling that a syllable in Standard Chinese, SC, contains a nasal coda, and (2) specify the acoustic attributes that distinguish between the two places of articulation for a nasal coda. The "rst syllable in SC disyllabic words with simple vowels [a], [i], and [ə] was examined in di!erent contexts: (1) vowel with a nasal coda [n]...

Due to the storage limitation and imperfect prediction, mobile computing devices may experience large delays when accessing data on the distributed file systems. Flinn et al. [4] have proposed a novel architecture, called Data Staging, in which nearby untrusted and unmanaged surrogates are used as the secondary file cache for the client to reduce the remote file operation latency. A prototype s...
