These are obtained non-destructively, without inducing fracture on the sample or requiring abrasive techniques that would potentially damage or alter the sample during sample preparation.
The different vaporization behavior of each component of an oil sample will alter the sample's chemical and isotopic composition, thus likely influencing the application of some identification methods based on these properties (Cañipa-Morales et al. 2003).
A possible solution, see [16], to restore sample diversity without altering the sample statistics is to move the current particles to new locations using a Markov chain transition kernel, that is, invariant to the conditional mixture pdf.
However, lower processing success rates for the more complex rotary-beam signals do reduce the yield of fundamental frequencies and alter the sample variances for the retrieved parameters and the detection rates for harmonics.
In this regard, we can use HSI system to measure the spectral signature of chemical components, like bacterial pigments, inside the cells without altering the sample and its measurements even in a heterogeneous medium where spectrophotometric signal is not resolutive.
Although the formation of Raman-based species maps is not fast, the technique offers the ability to use intrinsic chemical differences between cells to create multidimensional maps of microbial structures without extensive knowledge of the cells' genomes and without requiring any invasive sample preparation that could potentially alter the sample under study.
This is in contrast to adaptive designs that can alter the sample size based on interim results.
The power and significance level of the logrank test in the non-PH and PH scenarios are also studied without altering the sample size.
Supplementary Figures S2 and S3 show that in our data, altering the sample size made no visible difference to the estimated significance thresholds.
If we attempt to alter the sample pattern's last base C to any of the A, G, or T, none of them will report a match since we know the nonexistence of its prefix AGGTCGATTCGGGAC.
