The diffraction pattern of the stable SDMSO-I, using the first twenty peaks, indexed to an orthorhombic unit cell (Pna21, a = 11.0258 Å, b = 11.0049 Å, c = 8.1265 Å).
DOI: http://dx.doi.org/10.7554/eLife.03726.010 To statistically analyze the distributions for DL4 and DM6 ORNs, we determined their best-fit relationships using the first four peaks for both data sets, which had the most observations.
The diffraction pattern indexed to a tetragonal unit cell using the first twenty peaks with DICVOL04 and the space group was determined to be P42/ n based on a statistical assessment of systematic absences, as implemented in the DASH structure solution package.
The concentration of the aged (CdSe/ZnS -Cys quantum dot was CdSe/ZnS -Cysing the first excitonic absorption peak at 520 nm using ε = 5857(D)2.65 according to Yu's empirical calculation [20], where D(nm) is the diameter of the given nanocrystal.
Hence, we only determined the total protein content in the probed volume instead of attempting to quantify the protein conformation using the second derivative or peak deconvolution.
Charge states were calculated by using the first three isotopic peaks of a peptide and the same mass tolerances for detecting the mono isotopic peak as in the MASCOT search.
After removing the background signals and detecting peak position using the second derivative test, an optimal peak model is selected from a set of predefined peak models, including Gaussian mixture (GMM), log-normal (LN), Poisson, gamma, hybrid of exponential and Gaussian (EGH), and exponentially modified Gaussian (EMG) models.
The paternal subjects were used to confirm the third peak in the maternal plasma was a paternally inherited allele.
Individual cardiac cycles were identified using the first minimum that preceded the peak of the first derivative of LV pressure calculated digitally.
If the first period was less than 85% or more than 115% of the average of the next five periods, we concluded that the artifact interfered with the first poststimulus peak and instead used the second poststimulus peak for all measurements.
