In speech, acoustic cues are used to manifest a number of linguistic events including segmental phonemes and supra-segmental ones such as tones, prosodic phrasing structure, intonation, etc. It has been an interesting topic to quantitatively compare the importance of different linguistic events. However, previous studies have been mainly confined to segmental or segment-like units. No studies c...

BACKGROUND One prominent example of segmentation in vertebrate embryos is the subdivision of the paraxial mesoderm into repeating, metameric structures called somites. During this process, cells in the presomitic mesoderm (PSM) are first patterned into segments leading secondarily to differences required for somite morphogenesis such as the formation of segmental boundaries. Recent studies have...
