Contribution of Indirect Causes to Maternal Mortalities Based on a Methodological Approach to Clinical Epidemiology in Iran

Introduction: Level of mothers’ literacy, pregnancy history of more than four times, residence in villages, lack of receiving intensive care during pregnancy, as well as inaccessibility to obstetric emergency services have been reported, in Iran and the world, as major factors for maternal mortality. Considering significance of identifying indirect causes of maternal mortalitie...

First principles study of improper ferroelectricity in TbMnO3.

We carry out a first-principles theoretical study of the magnetically induced polarization in orthorhombic TbMnO3, a prototypical material in which a cycloidal-spin structure generates an electric polarization via the spin-orbit interaction. We compute both the electronic and the lattice-mediated contributions to the polarization and find that the latter is strongly dominant. We analyze the spi...
