Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]
arXiv, 2020 High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...

LC/ESI-MS analysis of underivatized amino acids and mass spectrum [PDF]
arXiv, 2016 We report the method of LC/ESI-MS analysis of underivatized amino acids with corresponding mass spectrum and fragmentation patterns. Diagnostic product ions determined by mass spectrometry can support the qualitative identification and quantitative estimation of individual amino acids. Therefore, the optimization of chromatographic separation using the

Correlations of Amino Acids with Secondary Structure Types: Connection with Amino Acid Structure [PDF]
arXiv, 2005 The correlations of primary and secondary structures were analyzed using proteins with known structure from Protein Data Bank. The correlation values of amino acid type and the eight secondary structure types at distant position were calculated for distances between -25 and 25.

Linguistic mechanism of the evolution of amino acid frequencies and genomic GC content [PDF]
arXiv, 2006 Much information is stored in amino acid composition of protein and base composition of DNA. We simulated the evolution of amino acid frequencies and genomic GC content by a linguistic model. It is showed that the evolution of genetic code determines the evolution of amino acid frequencies and genomic GC content.

Genetic Code Table: A note on the three splittings into amino acid classes [PDF]
arXiv, 2009 This note represents the further progress in understanding the determination of the genetic code by Golden mean (Rakocevic, 1998). Three classes of amino acids that follow from this determination (the 7 "golden" amino acids, 7 of their complements, and 6 non-complements) are observed now together with two further possible splittings into 4 x 5 and 5 x ...
