    "abstract": "Possible variations of the quark-meson coupling (QMC) model are examined in\nwhich the bag constant decreases in the nuclear medium. The reduction is\nsupposed to depend on either the mean scalar field or the effective mass of the\nnucleon. It is shown that the electric and magnetic radii of the bound nucleon\nare almost linearly correlated with the bag constant. Using the fact that the\nsize of the bound nucleon inside a nucleus is strongly constrained by\n$y$-scaling data in quasielastic, electron-nucleus scattering, we set a limit\nfor the reduction allowed in the bag constant for these two models. The present\nstudy implies that the bag constant can decrease up to 10--17 % at average\nnuclear density, depending on the details of the model.",
