The Category TOF [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
We provide a complete set of identities for the symmetric monoidal category, TOF, generated by the Toffoli gate and computational ancillary bits. We do so by demonstrating that the functor which evaluates circuits on total points, is an equivalence into ...

Validated MALDI-TOF/TOF mass spectra for protein standards [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2007
A current focus of proteomics research is the establishment of acceptable confidence measures in the assignment of protein identifications in an unknown sample. Development of new algorithmic approaches would greatly benefit from a standard reference set of spectra for known proteins for the purpose of testing and training.

De novo sequencing of peptides using MALDI/TOF-TOF [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2002
The recently developed MALDI TOF-TOF instrument yields relatively complex but interpretable fragmentation spectra. When coupled with a straightforward sequence extension algorithm, it is possible to develop complete peptide sequences de novo from the spectra.

Tandem Time-of-Flight (TOF/TOF) Mass Spectrometry and Proteomics [PDF]

open access: yesJournal of the Mass Spectrometry Society of Japan, 2005
A dual reflectron tandem time-of-flight (TOF/TOF) mass spectrometer reported in 1993 gave rise to the invention and development of the curved-field reflectron (CFR) for focusing product ions. The CFR is used in this case as the second mass analyzer in a tandem instrument (based on the Kratos AXIMA CFR) in which the first mass analyzer is a linear TOF ...
