The phrase "aligned spectrum" is correct and usable in written English.
It can be used in contexts related to physics, telecommunications, or any field discussing frequencies or wavelengths that are coordinated or matched.
Example: "The researchers presented their findings on the aligned spectrum of the signals, demonstrating improved communication efficiency."
Alternatives: "coordinated spectrum" or "synchronized spectrum".
As neighboring subcarriers have firmly aligned spectra, the adjacent subcarriers are modulated with the same, appropriately scaled data symbol in order to reduce the sidelobes power.
In the following we assume that the spectra are already aligned (as shown in Fig. 2) and describe the problem of peptide sequencing from multiple aligned spectra.
Because bicelle alignment is suppressed by MAS, the same sample can be used with and without MAS to record isotropic and weakly aligned spectra, respectively.
> -wrap-foot> Figure 7 presents a close view of aligned spectra from control group with m/ z range from 3300 to 4200 Da.
Figure 4B shows the aligned spectra in stacked mode, with an expansion of the fingerprint region for the side chains and sugar moieties.
Peak picking was then performed on the aligned spectra to detect mass peaks in each spectrum and this was performed using intensity weighted variance (IWV) algorithm as described by Jarman et al. [43].
The differential peptide abundance between daytime and nighttime for 173 peptides was assessed based on label-free integrated precursor ion intensity from chromatographically aligned spectra (i.e., SIEVE analysis).
Multi-spectra peptide sequencing problem The simultaneous sequencing of spectra from multiple peptides (e.g. PEPTIDE, PEPTID and EPTIDE) requires solving two problems: (i) finding the correct multiple alignment between all spectra (described in the next subsection) and (ii) reconstructing a maximal-scoring peptide from the aligned spectra.
While many existing 1D alignment methods have attempted to align each spectrum in a data set to a single consensus spectrum, the quality of these "star alignments" can suffer if there is wide chemical diversity between spectra, as any individual spectrum chosen as a star may not include the full complement of metabolites present in the other data sets.
