The ptychographical iterative engine (PIE) algorithm has been developed, which utilizes both the redundant information from the overlapping illumination areas on the sample and the iterative phase retrieval algorithms for the CDI, to reconstruct density distribution without the requirement of the sample being confined to a finite size smaller than the beam.
In order to define the environmental and technical requirements of the EXPOSE, the samples were subjected to the experiment verification test (EVT).
The essential requirement of this sample is that it should remain representative of the population of interest, because the intention is to generalize the data from it to the whole population of interest.
If the actual sample size cannot meet the requirements of a large sample size, the efficiency of the optimal plan based on the asymptotic variance is in doubt, which is pointed out in the 6th doubt. .
Therefore, the requirement of the training sample can be reduced, which makes the proposed approach more suitable for the heterogeneous clutter environments.
This means that in general, such principle could be used, according to the requirements of each sample, for acquiring aberration-corrected 3D images.
In the view of the requirement of the spectrum sampling, the dynamic-mirror drive system designed by this paper should provide the accurate interval signal for spectrum sampling as well as the dynamic-mirror-zero signal for starting sampling point.
In order to meet the minimum sample volume requirements of the IL-6 assay, dialysate samples were diluted 100-fold with calibrator diluent.
34 36 The proposed sample size is sufficient to comply with the precision requirements of a complex sample that assumes that the design effect is 1.5 and the prevalence of the risk factors of interest is 5% or greater (table 2).
The amount of time that would be saved by collecting data only for a limited period is compared with the consumed time for additional patients as a result of the requirements of a larger sample size.
