The first finding suggests that the formation of echo-chambers resulting from subscriptions to traditional media outlets is countered by the more serendipitous news sharing happening among users.
The formation of spin-echoes in the Carr-Purcell-Meiboom Gill (CPMG) NMR experiment on rubbery polybutadiene (PBD) has been studied as a function of temperature and CPMG inter-pulse spacing.
He warns of the formation of social media echo chambers, in which a very limited number of viewpoints are given precedence and perpetually reiterated on sites such as Twitter.
Key elements of the sequence are insensitivity to calibration of the transmit gain, the formation of a spin echo giving high-quality spectral information, and a small effective tip angle that preserves the magnetization for a sufficient duration.
TE, the echo time, is the time between the 90° radiofrequency excitation pulse and the formation of the spin-echo signal.
The theory of echo formation is used to derive exact gain functions which make the echo energy integral independent of the target range.
Fig. 9 A scheme of the IAR excitation by a lightning discharge and formation of the secondary echo-pulse observed on the ground.
The formation of the group echoes the big-money strategy used by now-Minority Leader Reid to keep Senate Democrats in power for the previous four years.
The vitreous chamber (5) is filled with a clear gel-like substance that is normally echo-free, although the formation of spots and linear echoes with aging is considered normal.
This condition is similar to that leading to formation of polar mesosphere summer echoes (PMSE).
He needed the reputation of Echo".
