In light of a recent Centers for Disease Control and Prevention report estimating 250 000 C. difficile infections per year resulting in 14 000 deaths and excess medical costs of $1 billion ...

The electronic band structure of Bi is calculated using state the art methods, including density functional theory and G$_0$W$_0$ quasiparticle approximations. delicate ordering states at L point Brillouin zone, which determines topological character bands, investigated in detail. effect on bands strain, changing structural parameters rhombohedral crystal structure, shown to be important determ...
