A mass spectrum-oriented computational method for ion mobility-resolved untargeted metabolomics. [PDF]
Nat Commun, 2023 The high dimensionality of ion mobility (IM)-resolved metabolomics data presents a great challenge to data processing. Here, authors develop a mass spectrum-oriented bottom-up assembly algorithm and the end-to-end computational framework Met4DX for IM ...

THE MASS SPECTRUM OF THE FIRST STARS [PDF]
The Astrophysical Journal, 2014 We perform cosmological hydrodynamics simulations with non-equilibrium primordial chemistry to obtain 59 minihalos that host first stars. The obtained minihalos are used as the initial conditions of local three-dimensional radiation hydrodynamics ...

Tandem Mass Spectrum Identification via Cascaded Search. [PDF]
J Proteome Res, 2015 Accurate assignment of peptide sequences to observed fragmentation spectra is hindered by the large number of hypotheses that must be considered for each observed spectrum. A high score assigned to a particular peptide–spectrum match (PSM) may not end up

Top-quark mass from the diphoton mass spectrum [PDF]
European Physical Journal C: Particles and Fields, 2017 We calculate the $$gg\rightarrow \gamma \gamma $$ g g → γ γ amplitude by including the $$t\bar{t}$$ t t ¯ bound-state effects near their mass threshold.

Standard Model mass spectrum in inflationary universe [PDF]
Journal of High Energy Physics, 2017 We work out the Standard Model (SM) mass spectrum during inflation with quantum corrections, and explore its observable consequences in the squeezed limit of non-Gaussianity. Both non-Higgs and Higgs inflation models are studied in detail.

Understanding the p/π ratio at LHC due to QCD mass spectrum [PDF]
Nuclear Physics A, 2014 Thermal fits have consistently reproduced the experimental particle yields of heavy ion collisions, however, the proton to pion ratio from ALICE Pb + Pb s N N = 2.76 TeV is over-predicted by thermal models – known as the p / π puzzle.

Compound identification in GC-MS by simultaneously evaluating the mass spectrum and retention index. [PDF]
Analyst, 2014 We report a compound identification method (SimMR), which simultaneously evaluates the mass spectrum similarity and the retention index distance using an empirical mixture score function, for the analysis of GC-MS data.
