Positive peritoneal fungal culture was common and was a significant risk factor for adverse outcome in patients with a PPU. A high MPI score could be used as an indicator for prophylactic antifungal therapy.

Surface stoichiometry and activity control for atomically smooth low dislocation density ZnO and pseudomorphic MgZnO epitaxy on a Zn-polar ZnO substrate by the helicon-wave-excited-plasma sputtering epitaxy method J. Appl. Phys. 108, 063541 (2010); 10.1063/1.3485600In situ monitoring of Zn* and Mg* species during helicon-wave-excited-plasma sputtering epitaxy of ZnO and Mg 0.06 Zn 0.94 O films This work utilizes low-energy sputtering to incorporate the generated nitrogen plasma into an epitaxial 1.4 nm Co film on the surface of a ZnO͑002͒ substrate. In this method, ultrathin Co-N amorphous films were formed. Interestingly, Co is key to the formation of Co-N films. Without the deposition of Co on the ZnO͑002͒, nitride films cannot be formed. Observations of the surface composition of the Co-N films after the firing of a N + ion beam onto it demonstrated that the surface concentration of Co reduced at the same rate as the reduction in the concentration of N upon successive sputtering. Theoretical calculations based on the Auger peak-to-peak amplitudes established that the composition of the amorphous Co-N thin films may be Co 3 N 2 .
