Sentence examples for appearance of high frequency from inspiring English sources
It is shown in [15,16] that for sufficiently regular initial values the regularity of the solution to the KdV equation is not diminished as it is evolved in time (although this does not rule out the appearance of high frequency oscillations).
The appearance of higher frequency band is due to the stretching vibration, while the lower frequency band is due to the bending vibration [37].
Perhaps the most notorious example would be the appearance of high-frequency triphasic waves in both hepatic encephalopathy and NCSE.
Appearance of higher frequencies than that of the linear modes can be interpreted as cascading three or multiple wave interactions using the matching conditions for frequencies ((omega _1 + omega _2 = omega _3 + cdots)) and wavevectors ((vec {k}_1 + vec {k}_2 = vec {k}_3 + cdots)) in a perturbation way.
Comparison to IR absorption spectra of PBTTT/PCBM blends in the first overtone/combination band region (0 2) as well as the appearance of higher order progressions confirm these are not fundamentals of high frequency modes (i.e., C H stretches).
As it happens, it is considerably harder to feel vibrations of high frequency than those of low frequency.
The Raman spectrum (Fig. 2b, middle trace) corroborates the β-sheet assignment with the appearance of a high frequency Amide I component at about 1,669 cm−1 and a strong Amide III component at approximately 1,240 cm−1.
These 'erosive' lesions differ from rheumatoid arthritis with respect to appearance and the high frequency of occurrence in gout cases.
However, overexpression of PLCζ resulted in the appearance of a delayed, second series of high-frequency Ca2+ oscillations that was consistently associated with plasma-membrane DAG production.
