    "abstract": "The modified quark-meson coupling model, which features a density dependent\nbag constant and bag radius in nuclear matter, is checked against the EMC\neffect within the framework of dynamical rescaling. Our emphasis is on the\nchange in the average bag radius in nuclei, as evaluated in a local density\napproximation, and its implication for the rescaling parameter. We find that\nwhen the bag constant in nuclear matter is significantly reduced from its\nfree-space value, the resulting rescaling parameter is in good agreement with\nthat required to explain the observed depletion of the structure functions in\nthe medium Bjorken $x$ region. Such a large reduction of the bag constant also\nimplies large and canceling Lorentz scalar and vector potentials for the\nnucleon in nuclear matter which are comparable to those suggested by the\nrelativistic nuclear phenomenology and finite-density QCD sum rules.",
