J. Dugundji,

Rice's formula ^1 for the "envelope" of a given signal is very cumbersome; in any case where the signal is not a single sine wave, the analytical use and explicit calculation of the envelope is practically prohibitive. A different formula for the envelope is given herein which is much simpler and ...

The relative significance of spectral and temporal envelopes for the synthesis of orchestral wind-instrument tones was evaluated by exchange of spectral and temporal envelopes among the wind instruments, by creation of artificial spectral envelopes, and by perturbation of the spectral envelopes. It was found that, for the oboe, clarinet, bassoon, tuba, and trumpet, where the spectral envelope is unique as regards the frequency of its ... in which the instrument is normally played, this envelope predominates in aural significance over the temporal envelope. ...

The mass of the envelope is about 10- of the total stellar mass (=5 395 Mo for all models) and the envelopes consist of either twenty or fifty mass zones. The temperature at the bottom of the envelopes is about 10 K, high enough so that the envelopes contain the entire He+ ionization region plus enough ...

Abstract Development of redundant nuclear envelope was observed in Erythrocebus patas and Macaca mulatta spermatids. As the acrosome forms around the anterior part of the nucleus, the underlying nuclear envelope becomes more dense in appearance. Changes which lead ultimately to formation of the redundant nuclear envelope of mature spermatozoa involve only the posterior region of the envelope which does not lie beneath the acrosome. The first recognized change is separation of the nuclear envelope from underlying chromatin by an intervening band of ...
