The first is based on the standard continualization of the equation of motion taken for a sequence of mass-spring lattices, while the second one exploits average processes valid in continuum mechanics.
A general characteristic of recent mass spectrometers is that most are composed of a sequence of multiple mass analyzers with different strengths and properties, resulting in tandem instruments that possess capabilities unattainable by the individual components (Fig. 1A).
The Dirac comb is given as the infinite sum, whose limit is understood in the distribution sense, :\Delta(x) = \sum_{n=-\infty}^\infty \delta x-n), which is a sequence of point masses at each of the integers.
Observed products mass spectra showed a remarkable sequence of mass peaks at regular intervals of mass number 24 in acetylene pyrolysis products and at intervals of mass number 26 in the case of ethylene pyrolysis products, indicating the role of particular corresponding radicals such as C2H and C2H3 in products formation.
A peptide is a sequence of amino acids, and the mass of a peptide is the total mass of amino acids in the peptide.
The dynamic stability of girders under a sequence of equidistant concentrated load masses was estimated for vertical vibration and horizontal flexural-torsional vibration and the behavior of a girder under a load sequence of equidistant half-vehicle models was investigated by numerically integrating the equations of motion of the girder and the half-vehicle models.
Drawing on material in several European languages, including memoirs and scholarly literature, Snyder recounts this sequence of mass murder — by Stalin and then by Hitler — which accounted for 14 million civilian deaths in little more than a dozen years.
"For sure this is an experiment but to have a sequence of Bosco Verticales, to reach a critical mass, this could be quite interesting," says Boeri. "To deurbanise the urban environment is a radical alternative to expensive technology".
A mass spectrum data sample includes a sequence of mass/charge (m/z) ratios.
It is suitable to globally align chromatograms, which are sequences of mass spectra.
Of the phosphopeptides that were identified, manual sequencing of mass spectra unambiguously localized the site of phosphorylation on 549 of the peptides.
