Publication number: 20230326558Abstract: Peptide sequencing is important in decoding data stored in a data-encoded peptide. Tandem mass spectrometry (MS/MS) is particularly useful for peptide sequencing. In a computer-implemented method for sequencing the data-encoded peptide from an experimental spectrum, raw data of the experimental spectrum are first preprocessed to remove uninterpretable peaks to yield preprocessed data. A first set of one or more candidate sequences contending for a peptide sequence of the peptide is identified from a spectrum graph. The spectrum graph is formed according to the preprocessed data rather than the raw data for generating a fewer number of candidate sequences to thereby reduce a time cost in sequencing. The first candidate-sequence set is then processed to estimate the peptide sequence to thereby obtain a set of peptide-sequence estimate(s). Each estimate is verified whether it is invalid. The set of peptide-sequence estimate(s) is purged to remove any invalid estimate.Type: ApplicationFiled: April 10, 2023Publication date: October 12, 2023Inventors: Zhongping YAO, Cheuk Chi NG, Francis Chung Ming LAU, Wai Man TAM

Patent number: 11772972Abstract: The present disclosure relates to a green method for producing and exploiting multiple nano-carbon polymorphs from coal commonly known as anthracite, meta-anthracite, and semi-graphite. The method disrupts the prevalent environmentally unfriendly practices of burning coal with poor profitability and sustainability because the method yields an unexpectedly rich mixture of high-performance nano-materials, comprising carbon nano-fibers, carbon nano-tubes, carbon nano-onions, nano-graphite-plates, and nano-graphene-disks, by simply mechanically-comminuting coal to nano-size, with minimal sorting efforts. The resulting total-yield of nano-carbon polymorphs is over 50% by weight from properly selected coal. Innovative means are added to the prevalent comminution and sorting practices to further reduce energy and chemical consumption. More importantly, the method also refines the comminution and sorting details for producing the best custom-made formulations.Type: GrantFiled: September 10, 2018Date of Patent: October 3, 2023Assignee: HL Science & Technology LimitedInventors: Leo Woon Ming Lau, Aixian Shan
