Using Monte Carlo simulations and finite-size scaling, we investigate the critical behavior of two-dimensional magnetic lattice gas at densities ρ=0.90, 0.95, 1.0. There is a ferromagnetic phase transition at each density. As expected, the critical temperature T <Subscript> c </Subscript> depends on system...</subscript>

Primary healthcare institutions (PHIs) in China have experienced a sizable decline in medical services in recent years. Despite the large regional disparities in China, there is a lack of evidence on the differential patterns of medical services offered by PHIs, especially from a spatial...
