    "abstract": "We perform calculations of the dependence of nuclear magnetic moments on\nquark masses and obtain limits on the variation of the ratio of quark mass and\nstrong interaction scale (m_q/Lambda_{QCD}) from recent atomic clock\nexperiments with hyperfine transitions in H, Rb, Cs, Yb+, Hg+ and optical\ntransition in Hg+. Experiments with Cd+, deuterium/hydrogen, molecule SF_6,\n  Zeeman transitions in He_3/Xe are also discussed.",
