Sentence examples for peak combinations from inspiring English sources

The total number of all possible 3-tuple peak combinations in samples thereby reduced by around seven orders of magnitude to averages of 4.3 × 105 and 1.0 × 105 3-tuples for the positive and negative ionization mode, respectively.

The extracted peaks are then successively recombined to screen for all unique peak combinations that can form 3-tuples in accordance with the above series definition and that include the current center peak as the second element of a triplet (cp. green and blue dots in Fig. 1).

To find the best quantitation parameters for the pipeline, we systematically investigated a series of isotopic peak combinations (either peak area or height) of three abundant pairs of sialylated glycans (m/ z: 2405.9 vs 2411.9, 3075.2 vs 3081.2, and 3379.3 vs 3385.3, Figure 3B) from all spectra.

After evaluating several approaches, it was determined that the summing of multiple isotopic peaks, and the use of peak height rather than area, was the most effective strategy to minimize these variations and to maximize ratio accuracy, such as the peak height combination of 1 3 or 1 4.

In this study, we collected 218 cyst fluid samples, 192 were diagnosed with benign, borderline type, and malignant ovarian tumors of different histology and stages and analyzed with SELDI-TOF MS. Five most significant peaks were identified and a peak combination with highest ROC AUC was evaluated.

Si40Ti60 composite bands, at 396, and 639 cm-1, suggests anatase and rutile peaks combination (Figure 2-B).

Therefore, the height combination of peaks 1 3 was chosen as the signals for the quantitative calculation, rather than a single monoisotopic peak as previous approaches.

As shown in Figure 4C, the calculated standard curve from three pairs of sialylated glycans had a nearly linear relationship (R = 0.9893) over the full range (10 1 to 1 10) by the height combination of peaks 1 3, indicating that the DRAG strategy had a similar 10-fold dynamic range, comparable to other single-modification strategies while analyzed by MALDI-MS.

An internal calculation algorithm (Superspectra™ function for selection of specific biomarkers) was applied to recognize if certain peaks or combinations of certain peaks might be associated with specific PCR ribotypes.

The surface distribution of instability for a TTR system under multi-frequency parametric and vortex-shedding excitations was analyzed on the basis of various significant wave height and wave peak period combinations, and extreme sea states were considered to determine the maximum strength of a TTR.

Oxidation His peak, in combination with Tyr and Trp oxidation responses may find use in label-free analysis of numerous proteins, including those important in biomedicine.
