sinusoidal pattern

sinusoidal pattern

An abnormal fetal heart rate finding in which the monitor records a consistent rhythmic, uniform, undulating wave. Although the number of beats per minute is within normal limits and the recording shows long-term variability, beat-to-beat variability is absent and no accelerations in heart rate occur with fetal movement.

However, fetal heart rate abnormalities, including decreased fetal heart rate variability and a sinusoidal pattern, have been associated with fetal intracranial hemorrhage [12-14].
In that work, the authors use a TPE method with an intensity modulation that emulates a sinusoidal pattern in the object plane.
Caltrans' design goal was a sinusoidal pattern that minimizes the "harsh" impulse noise from existing rumble strip designs but still increases interior noise levels by 6 dB or more.
The best fade patterns are half sinusoidal (ref Figure 8B) in nature and may be halftone or other types of fade technologies since a sinusoidal pattern has the lowest number of Fourier spatial frequencies.
The charge-density waves occur when electron density in a conductor is distributed in a sinusoidal pattern, like ripples on water, instead of the common uniform density.
The sinusoidal pattern is also noted in the liver (Figure 2, A), causing sinusoidal dilation and sometimes perisinusoidal fibrosis without portal triad involvement.
At a critical speed, the crack will become unstable, branching in a sinusoidal pattern, until it slows and stops.
A prominent burrowing sinusoidal pattern was present (Fig.
Criteria include a sinusoidal pattern or absent baseline FHR variability and any of the following--recurrent late decelerations, recurrent variable decelerations, or bradycardia.
In general, most teeth followed the normal saturation potential pattern as shown by the high correlation coefficient values (around 0.9), except for diabetic rat (rd3) which appeared to follow a sinusoidal pattern. The maximum mineral concentration ranged from 2.15 to 2.71 g cm3 with the maximum mineral concentration for mandibular incisors being slightly higher than that of maxillary incisors, and that of mice higher than rat.
