Superconductivity in non-centrosymmetric BiPd system

In this work, we establish the bulk superconductivity of a high quality sample of monoclinic BiPd ($\alpha$-BiPd, space group P2$_1$) below 3.87 K by studying its electrical resistivity, magnetic susceptibility and heat capacity. We show that it is clean type-II superconductor with moderate electron-phonon coupling and determine its superconducitng and normal state parameters. Although $\alpha$-BiPd is a noncentrosymmetric superconductor with large electronic heat capacity (therefore, large $\gamma$), the effect of spin-orbit splitting of the electronic bands at the Fermi level is small. This makes little influence on the superconducting properties of $\alpha$-BiPd.Comment: 6 pages; 6 figures. Submitted to Phys. Rev.

Classical supravalvar aortic stenosis and peripheral pulmonary stenosis

Supravalvar aortic stenosis as well as peripheral pulmonary stenosis are rare forms of congenital heart disease, which occur, however, relatively frequently in association. This article reports and discusses the classical findings of SVAS and PPS upon clinical examination and imaging in a sixyear-old girl that presented with repeated respiratory tract infections and failure to thrive.peer-reviewe
