The phrase "a small attenuation in" is correct and usable in written English.
It can be used in contexts discussing a minor reduction or weakening of a signal, effect, or quality.
Example: "The experiment showed a small attenuation in the signal strength after passing through the material."
Alternatives: "a slight decrease in" or "a minor reduction in".
The adjustment for covariates (model 2) resulted in a small attenuation in the strengths of most associations but did not radically change the pattern of results.
CATs under these rules used a relatively low number of items, showed a substantive correlation with the original latent depression estimates, and had a small attenuation in criterion-related validity.
The distribution of MARK3 and MARK4 granules in CA-neurons correlated well with CK1δ granules and all three markers increased in a Braak-stage dependent manner, except for a small attenuation in CA1-CA2 at Braak stage VI.
The addition of temperature variabilities also does not change these parameter estimates, except for a small attenuation in the estimate for the relationship between daily minimum temperatures and SBP (Table 2).
When a broad-band light propagates along the optical fiber to a grating, a single wavelength is reflected back while therest of the signal is transmitted with a small attenuation (shown in Figure 17).
In contrast, there were small attenuations in the longitudinal part of the model after these adjustments.
The small attenuation seen in the positive BOLD activation within this area is likely from the limited intravascular contribution of the small vessels, which may include venules and capillaries.
This led to a further small attenuation of the effect of deprivation (0.86, 0.70 to 1.05).
The small attenuation (∼16%) in capacitance of PEDOT NiFe2O4 composite over 500 continuous charging/discharging cycles suggests its excellent electrochemical stability.
The proposed method is verified to be robust with respect to un-modeled small attenuations, present in the flexible structure, and to measurement noise.
This concurs with the simulation findings of Sheppard et al. [ 12] who reported a "small but noticeable" attenuation in the heath effect estimate when ambient area exposure to PM2.5 was based on a single pollution monitor, but little if any attenuation when area exposure was based on the average across 3 or 10 monitors.
