background: coagulase negative staphylococci (cons) are one of the most common bacteria found on human skin and on mucous membranes as a component of normal flora. the presence of cons in clinical specimens is frequently associated with an infectious aetiology or contamination. objectives: we aimed to evaluate cons species distribution and susceptibility patterns in specimens obtained from clin...

This paper introduces a development of a normalized axial velocity distribution function and a susceptibility term for an electron beam m a planar wiggler FEL. The model includes the independent contributions of the energy spread and the angular spread, the ennttance and the betatron motion, to the axial velocity distribution function. In the case of an emittance dominated spread, the resulting...

The magnetic susceptibility of the diluted magnetic Lu22xGdxO3 ~x50.06, 0.10, 0.22, 0.40, 1.00, 1.40, 1.80! was measured in the temperature range 1.7–295 K. The inverse susceptibility changes slope to a smaller value below 2.2 K for the samples with x<0.40. In the cubic Lu0.20Gd1.80O3 the slope increases below 2.8 K. These changes are attributed to the large difference in susceptibility for two...

background: to determine the species distribution, updated drug susceptibility patterns and genes conferring resistance in clini­cal vancomycin resistant enterococcal (vre) isolates. methods: clinical enterococcal isolates collected during 7 months, from september 2005 to april 2006 from hos­pitalized pa­tients and outpatients were studied. twenty five vre were isolated from 450 enterococci sam...

This study deals with the 3D recovering of magnetic susceptibility model by incorporating the sparsity-based constraints in the inversion algorithm. For this purpose, the area under prospect was divided into a large number of rectangular prisms in a mesh with unknown susceptibilities. Tikhonov cost functions with two sparsity functions were used to recover the smooth parts as well as the sharp ...

PURPOSE To implement a method using a tailored radiofrequency (TRF) pulse with a quadratic phase profile to recover susceptibility-induced signal losses in gradient-recalled echo-planar images (EPI). MATERIALS AND METHODS A functional magnetic resonance imaging (fMRI) experiment for compensation of susceptibility artifacts, known as the TRF pulse EPI sequence (TRF-EPI), was used. TRF pulse co...
