The phrase "appears in the frequency" is correct and usable in written English.
It can be used when discussing occurrences or patterns within a set of data, particularly in contexts like statistics, research, or analysis.
Example: "The term 'sustainability' appears in the frequency of the survey responses, indicating a growing concern among participants."
Alternatives: "is found in the frequency" or "occurs in the frequency".
A semicircle appears in the frequency region from 10 Hz to 10 kHz for each cell, which can be attributed to an interfacial charge transfer.
The double negative property appears in the frequency range 955 1000 MHz in 40 wt% MWCNTs/PANI composites, 930 1000 MHz in 50 wt% MWCNTs/PANI composites, 925 1000 MHz in 60 wt% MWCNTs/PANI composites and 915 1000 MHz in 70 wt% MWCNTs/PANI composites.
The second feature is the small peak that appears in the frequency range between 1 and 1.5 Hz.
This analysis separates out the noise due to the contact resistance which appears in the frequency-independent Nyquist noise.
The peaks appeared in the frequency response curve are resonant frequencies.
This phenomenon has been clearly visualized by AE signals, appearing in the frequency range between 330 and 420 kHz.
The large values of F score mainly appear in the frequency band over 20 Hz for this example, which is quite similar to the distribution of Euclidean distance.
The MSW waves are observed in a frequency range of a few hundred kilohertz at L ∼ 4 (Santolík et al. 2002), and the ECH waves appear in the frequency range of f > fce (Kennel et al. 1970).
Whistler-mode chorus waves appear in the frequency range below the electron gyrofrequency fce and have distinct upper and lower frequency bands, which are identified by a gap of 0.5 fce (Burtis and Helliwell 1969; Tsurutani and Smith 1974).
Using hypocenter data from the EHB catalog (Engdahl et al. 1998; Engdahl and Villaseñor, 2002), they verified the presence of the double seismic zone by investigating whether two peaks appear in the frequency distribution of intermediate-depth intraslab earthquakes with respect to the distance from the slab upper surface.
Spacecraft observations near the magnetic equator have revealed that chorus appear in the frequency range from 0.2 to 0.8 Ωe 0, where Ωe 0 is the electron gyrofrequency at the magnetic equator, while the frequency range of chorus is classified into the lower-band (0.2 to 0.5 Ωe 0) and upper-band chorus (0.5 to 0.8 Ωe 0) by a distinct gap at 0.5 Ωe 0 (Santolík et al. 2003).
