Sentence examples for drift of the sample from inspiring English sources
This method has been proven useful but can yield poor results, as small cumulative errors may result in a serious drift of the sample [8].
In this case, attention should be paid to a possible spatial drift of the sample with time, as its effects on the final geometry of the specimen will be more pronounced.
The upper limit originates from the fact that the drilled holes start to be asymmetric for diameters larger than 150 nm (200 nm without SCM) because of charge drift and/or mechanical drift of the sample stage (both these effects increase with larger milling time).
A major challenge, which has hindered the use of OPT for microscopic imaging in vivo, is the residual random movement and drift of the sample during the course of observation, which becomes increasingly significant at higher magnifications required for microscopic OPT [12].
Finally, residual 3D drift of the sample was corrected in MatLab (MathWorks, Natick, MA) based on Gold Nanorod fiducials.
Background subtraction was performed using the 'Subtract Background' tool (rolling ball radius 30 40 pixels), and the 'StackReg' plugin was used to correct focal drift of the sample.
The CNT network heater can heat samples up to extremely high temperature, as high as >2000 °C, while minimizing the spatial drift of the samples induced by the heating.
In addition, the DRIFT spectrum of the sample with amino/methyl groups (AM, not presented here) has sharp absorption band at 1273 cm−1, which is absent in the DRIFT spectra of other samples and can be attributed to δs(CH3) of methyl group bond to a silicon atom [16].
As can be seen from (13), the existing time and phase synchronization errors result not only in a drift of the echo sampling windows which will cause RCM errors but also in the distortion of the azimuth-dependent phase history.
In the DRIFT spectra of the samples A and DA, the absorption band at 1590 1597 correspondingonding to δ(NH2) bending of the amino groups, is clearly visible.
In addition, the DRIFT spectra of the samples with polysiloxane layer contain an intense absorption band with high-frequency shoulder in the region of 1000 1200 cm−1, which is characteristic of the νas(SiOSi) stretching vibrations.
