    "abstract": "Within the relativistic mean-field approach, we extend the Miyazaki model,\nwhere the NN$\\sigma$ and NN$\\omega$ interactions are modified to suppress the\ncouplings between positive- and negative-energy states of a nucleon in matter.\nAssuming appropriate density-dependence of the meson-nucleon couplings, we\nstudy nuclear matter and finite nuclei. The model can reproduce the observed\nproperties of $^{16}$O and $^{40}$Ca well. We also examine if the model is\nnatural.",
