In quantum mechanics, when an electron is quickly ripped off from a molecule, superposition of new eigenstates the cation creates wave packet that governs charge flow inside, which has been called migration (CM). Experimentally, extracting such dynamics at its natural (attosecond) timescale quite difficult. We report first experiment in linear carbon-chain butadiyne (C4H2), via high-harmonic sp...

Human high Mr kininogen was purified from normal plasma in 35% yield. The purified high Mr kininogen appeared homogeneous on polyacrylamide gels in the presence of sodium dodecyl sulfate and mercaptoethanol and gave a single protein band with an apparent Mr = 110,000. Using sedimentation equilibrium techniques, the observed Mr was 108,000 +/- 2,000. Human plasma kallikrein cleaves high Mr kinin...
