New flier glides into the Pacific

Linking fluids as they twist and writhe Helicity is a measure of corkscrew-like motion described by the amount of twisting, writhing, and linking in a fluid. Total helicity is conserved for ideal fluids, but how helicity changes in real fluids with even tiny amounts of viscosity has been an open question. Scheeler et al. provide a complete measurement of total helicity in a real fluid by using ...

Mitophagy: New Insight into the Cardiovascular Aging  

Discrimination of frequency glides with superimposed random glides in level.

These experiments were designed to test the hypothesis that glides in frequency are detected and discriminated by monitoring changes in excitation level on the low-frequency side of the excitation pattern. Thresholds were measured for detecting an increase in the extent of a frequency glide, for various standard extents (transition spans). The center frequency of each stimulus was roved, to pre...

Phonemic vs. Derived Glides

Partial preparation of this manuscript was supported while on a postdoctoral training grant from the National Institutes of Health to Indiana University (NIHNIDCD T32 Train...

Glides, Vowels, and Features

Generative phonologists usually take high vowels like [i,u] and glides like [j,w] to be identical (respectively) in terms of distinctive features. The main argument for this assumption comes from theoretical economy: since syllable theory independently provides us with a means of distinguishing between vowels and glides – as syllable nuclei and margins respectively – there is no need for a feat...
