The phrase "a small irregularity in" is correct and usable in written English.
It can be used to describe a minor flaw or deviation in something, such as a process, document, or physical object.
Example: "The report contained a small irregularity in the data analysis that needed to be addressed before submission."
Alternatives: "a minor discrepancy in" or "a slight deviation in".
It turned out to be a fibroid -- a benign tumor of the uterus -- but in the operating room, the surgeon noted a small irregularity on the surface of her left ovary.
But the researchers also found that even small irregularities in a person's walking are important: These amplify the wilder oscillations, or sloshing, which bumps up the chance of a spillage.
The peaks are generally more asymmetric for both the image resulting from a relaxed crystal and from a thermal average of crystals, and these small irregularities in the symmetry of adjacent intensity peaks can cause large measurement errors, as illustrated in Fig. 4. All results in the following sections will be based on simulations where temperature effects are included.
We use the metaphor of waves that rise and fall in societies, perhaps forgetting that the actual waves of the ocean are purely opportunistic, small irregularities in water that, snagging a fortunate gust, rise and break like monsters, for no greater cause than their own accidental invention.
The omentum can repair small irregularities in breast contour, achieving a natural result different from all other flaps.
Unlike signals in the longer-wavelength HF band, for which layers in the atmosphere appear as relatively smooth reflective surfaces, signals in the shorter-wavelength UHF band reflect off small irregularities in the atmospheric layers as if these irregularities were randomly oriented granular reflectors.
In big waves, where brute strength and stability become critical factors, his height, combined with his hunkered-down style, seems to work to his advantage: he uses it to lever the long, hard, high-speed turns that big waves avail, and to absorb the sharp, powerful shocks that even small irregularities in the surface transmit at high speed.
Small irregularities in the CMB have been used to deduce what the early universe looked like, and thus how much cold, dark matter and dark energy there is around.In this section Bouillabaisse sushi Things fall apart Elements of style Crystal clear?
The "adaptive optics" compensate for the many small irregularities in our eye's lens so that single cones could be targeted by a flash of light.
