Machine learning meets mass spectrometry: a focused perspective [PDF]
Mass spectrometry is a widely used method to study molecules and processes in medicine, life sciences, chemistry, catalysis, and industrial product quality control, among many other applications. One of the main features of some mass spectrometry techniques is the extensive level of characterization (especially when coupled with chromatography and ion ...

Mining Mass Spectra: Metric Embeddings and Fast Near Neighbor Search [PDF]
Mining large-scale high-throughput tandem mass spectrometry data sets is a very important problem in mass spectrometry based protein identification. One of the fundamental problems in large scale mining of spectra is to design appropriate metrics and algorithms to avoid all-pair-wise comparisons of spectra. In this paper, we present a general framework

Application of computational quantum chemistry to chemical processes involved in mass spectrometry [PDF]
The field of application of mass spectrometry (MS) has increased considerably due to the development of ionization techniques. Other factors that have stimulated the use of MS are the tandem mass spectrometry (MS/MS) and sequential mass spectrometry (MSn)

Monolysocardiolipin in cultured fibroblasts is a sensitive and specific marker for Barth Syndrome
Barth Syndrome (BTHS) is an X-linked recessive disorder that results in abnormal metabolism of the mitochondrial phospholipid cardiolipin (CL). CLs are decreased and monolysocardiolipins (MLCLs), intermediates in CL metabolism, are increased in a variety

Towards Less Biased Data-driven Scoring with Deep Learning-Based End-to-end Database Search in Tandem Mass Spectrometry [PDF]
Peptide identification in mass spectrometry-based proteomics is crucial for understanding protein function and dynamics. Traditional database search methods, though widely used, rely on heuristic scoring functions and statistical estimations have to be introduced for a higher identification rate.
