    Enantioselective HS-SPME-GC-MS for Authentication of Natural and Synthetic Strawberry Flavour in Syrups by Karolína Průchová, Adéla Grégrová, Hana Helísková, Vojtěch Kružík, Helena Čížková

    Published 2022-09-01
    “…Demand for a reliable distinction of the strawberry flavour naturalness stood in the beginning of this research. An efficient chiral column with CP-Chirasil-Dex CB stationary phase was involved in headspace solid-phase microextraction-gas chromatography-mass spectrometry analysis of strawberry flavour in 6 strawberry cultivars, 7 samples of strawberry flavourings and 14 samples of strawberry syrups to evaluate the authenticity of flavour naturalness and reveal adulteration. …”

    An Approach to Classical Quantum Field Theory Based on the Geometry of Locally Conformally Flat Space-Time by John Mashford

    Published 2017-01-01
    “…Classical quantum field theory (the Dirac equation and Maxwell’s equations) is obtained by considering representations of the structure group K⊂SU(2,2) of a principal bundle associated with a given Möbius structure where K, while being a subset of SU(2,2), is also isomorphic to SL2,C×U(1). The analysis requires the use of an intertwining operator between the action of K on R4 and the adjoint action of K on su⁡(2,2) and it is shown that the Feynman slash operator, in the chiral representation for the Dirac gamma matrices, has this intertwining property.…”

    LHC Signatures of Vector-Like Quarks by Yasuhiro Okada, Luca Panizzi

    Published 2013-01-01
    “…Searches at Tevatron and at the LHC, here listed and shortly described, have not found any evidence for new heavy fermionic states (either chiral or vector-like) and have therefore posed strong bounds on their masses: depending on specific assumptions on the interactions and on the observed final state, vector-like quarks with masses up to roughly 400–600 GeV have been excluded by all experiments. …”
