Isotopic peak pattern deconvolution for Protein Mass Spectrometry by template matchingMartin SlawskiRene Hussong
we extract thirteen features to design the quality classifiers. These features are mass deviation (MassDev), signal to noise ratio (S/N), preceding peak ratio (PPR), six isotope deviations (IsoDevs) and four scan isotope pattern deviations (SIDs). These features are discussed in “...
CAIs exhibit a specific, characteristic pattern of oxygen isotope abundances. Within an individual CAI, different minerals have different isotopic compositions, with all data points falling on a straight line in the three-isotope graph. This behavior is illustrated in Figure 3, based on analyses of...

Spatial pattern of plutonium and radiocaesium contamination released during the Fukushima Daiichi nuclear power plant disaster Plutonium and radiocaesium are hazardous contaminants released by the Fukushima Daiichi nuclear power plant (FDNPP) disaster and their distribution in the ...

Major advances in genome sequencing and large-scale biosynthetic gene cluster (BGC) analysis have prompted an age of natural product discovery driven by genome mining. Still, connecting molecules to their cognate BGCs is a substantial bottleneck for this approach. We have developed a mass-spectrometr...
Tandem mass spectrometry has also become a state-of-the-art platform for the characterization of high-throughput peptides and proteins. The interpretation of tandem mass spectra is the final, yet para- mount, step of this platform. Overlapping isotopic envelopes (OIEs) are very common in these ...
tendedData Fig. 2). This patternargues against significant metasomatic overprinting. The narrowrange in d 15 N bulk close to the presumed composition of the atmosphere is inconsistent with an excess supply of fixed nitrogen fromabiotic sources, because partial assimilationof either NH ...
In addition, the rare earth elements distribution normalized to chondritic values are homogeneous and the general pattern is relatively flat, with a weak enrichment of light rare earth elements (LREE) with respect to heavier rare earth elements (HREE) (LaN/YbN = 2.1–11.3). No anomalies are ...
The stable carbon isotopic distribution of methane (CH4) and its homologues (C2–5) in the studied wells are characterized by a normal pattern (δ13C-CH4 < δ13C-C2H5 < δ13C-C3H6) (Fig.3). The studied samples have heavier isotopic compositions of ethane and propane, ranging ...
