(n.) A trough or sluice having cleats, grooves, or steps across the bottom for holding quicksilver and catching particles of gold when auriferous earth is washed; also, one of the cleats, grooves, or steps in such a trough. Also called ripple.
Example Sentences:

(3) "I hope there is no return to the spirit of loadsamoney heartlessness – figuratively riffling banknotes under the noses of the homeless – and I hope that this time the Gordon Gekkos of London are conspicuous not just for their greed – valid motivator though greed may be for economic progress – as for what they give and do for the rest of the population, many of whom have experienced real falls in their incomes over the last five years."
(4) Each stream was divided into pool and riffle sections that were colonized by communities of periphyton and invertebrates.
(5) The 488-m long stream was composed of mud-bottomed pools alternating with gravel riffles.
(6) Its use is demonstrated with a comparison of biomass and neuromass distributions for a stream riffle ecosystem in the Huron River, southeastern Michigan.
(7) The vaccine failed to protect against a highly virulent form of E coli 06 (Riffle), possibly because the amount of antibody to its lipopolysaccharide was inadequate.
(8) I searched for some explanation for this overweening neediness, riffling the pages with rising desperation.
Wavelet
Definition:
(n.) A little wave; a ripple.
Example Sentences:
(1) Positive wavelets preceding the primary cortical response were also diminished by the occlusion, suggesting that ischemia affected the thalamocortical white matter.
(2) Most significantly, however, it can also track sporadic or nonstationary irregularities in the shape of an individual acoustic wavelet.
(3) Wavelets were introduced by Grossman and Morlet in 1984.
(4) Latency and amplitude for various wavelets were plotted against signal intensity.
(5) The number of circuits and wavelets increased in a dose-dependent fashion.
(6) These functional distinctions between the last and the earlier wavelets are consistent with their representing the activity of different retinal generators.
(7) As the electrode was advanced proximally, the wavelets disappeared as a function of retinal depth.
(8) Following far-field potential of P14 after median nerve stimulation, we identified several small wavelets, designated here as fast frequency potentials or FFP, over the ascending and descending phases of the major negative wave of 'N20.'
(9) The spin density can be reconstructed with an inverse wavelet transform.
(10) Each wavelet had an amplitude maximum at a certain stimulus intensity level.
(11) It was supposed that this was the site of re-entry for a cycling wavelet subsidiary to the main flutter wave.
(12) It is often preceded by a brief wavelet of depolarization ascribed to the so-called back-response.4.
(13) Oscillatory potentials resembling those seen in human VEPs are observed riding on N40; analysis of MUA in conjunction with sources and sinks coincident with these wavelets provides evidence that they derive from both thalamocortical and cortical activity.
(14) Wavelets are already used for speech recognition, geophysics investigations and fractal analysis.
(15) The OPs consisted of three to four wavelets with a mean peak interval of approximately 6.5 msec, consistent with that recorded with conventional full-field stimuli over the entire retina.
(16) Rods responded to red flicker with discrete wavelets up to 5 Hz.
(17) Regardless of the number of OP wavelets, the last OP wavelet increased in amplitude and decreased in implicit time to a greater extent than did the earlier wavelet(s).
(18) HNR, however, is usually inflated by cycle-to-cycle variations of fundamental frequency period because zero padding is used for time normalization of the wavelet.
(19) Other time-frequency representations, such as the Wigner distribution, short-time spectral estimators, and the wavelet transform, have also been investigated.
(20) The wavelet transform, which is the decomposition of a signal into a set of independent frequency channels, is shown to be a useful diagnostic tool in the analysis of heartbeat sounds.
