Spin tunnel junctions fabricated with one interposed Fe–FeOx layer between the Al2O3 barrier and the top CoFe pinned electrode show large tunneling magnetoresistance ~TMR! ~40%! for anneals up to 380 °C. The annealing temperature TTMR * , where maximum TMR occurs, increases with the inserted Fe–FeOx layer thickness. For samples with thicker inserted layer, the pinned layer moment ~which usually...

abstract background: peripheral insertion of central catheters can be difficult in neonates. we compared the success rates of peripherally inserted central catheters by two methods of using static ultrasound and traditional technique (vein visualization and palpation) in neonates. materials and methods: in a prospective randomized, controlled trial, 52 neonates with birth weight lower than 1500...

entral venous (CV) lines have been the subject of much professional debate and public exposure in the UK following an enquiry into the deaths of four children in Manchester as the result of cardiac tamponade. One of the recommendations of this review was that CV line tips should not be placed within the cardiac outline. 1 This has been the recommendation of CV line manufacturers for some time. ...

The role of bathocuproine BCP buffer layer inserted between active layer and Al contact in photovoltaic cells based on phthalocyanine Pc and C60 was investigated. Photoluminescence PL experiments show exciton quenching at the C60–Al interface to be strongly reduced by inserting BCP. Current-voltage characteristics of photovoltaic cells with planar geometry front electrode/ Pc/C60/BCP/Al show th...

This paper begins a series studying D-modules on the Feigin-Frenkel semi-infinite flag variety from the perspective of the Beilinson-Drinfeld factorization (or chiral) theory. Here we calculate Whittaker-twisted cohomology groups of Zastava spaces, which are certain finite-dimensional subvarieties of the affine Grassmannian. We show that such cohomology groups realize the nilradical of a Borel ...

background: peripherally inserted central catheter (picc) is commonly used in nursing for patients with leukemia. the purpose of this study was to investigate the risk factors of catheter-related infection (cri) in patients with leukemia and to provide some nursing strategies based on the results. methods: clinical data from 140 patients with leukemia between may 2014 and july 2016 in haiyang p...
