- Transitions in an artificial atom, driven nonadiabatically through an energy-level avoided crossing, can be controlled by carefully engineering the driving protocol. We have driven a superconducting persistent-current qubit with a large-amplitude radio-frequency field. By applying a biharmonic wave form generated by a digital source, we demonstrate a mapping between the amplitude and phase of the harmonics produced at the source and those received by the device. This allows us to image the actual wave form at the device. This information is used to engineer a desired time dependence, as confirmed by the detailed comparison with a simulation. © 2009 The American Physical Society.

- We investigated myeloid-dendritic cell (DC) marker and Toll-like receptor (TLR)-2 and 4 distributions in ileal samples from Crohn's disease (CD) patients (n = 14) and controls (n = 13). In controls, no TLR-2+ cells were observed, and higher numbers of TLR-4+ and DC-SIGN+ cells (P < 0.01) were detected in ileal samples when compared versus colonic tissues. In non-inflamed CD ileum, TLR-4+ and DC-SGN+ cells were depleted from superficial areas of the villus, and a significant CD1a+ cell infiltration (P < 0.01) was observed when compared to ileal controls and non-inflamed colonic CD samples. In inflamed CD ileum, DC-SIGN+, CD1a+, TLR-4+ and few TLR-4 +DC-SIGN+ cells were detected as well as CD83 depletion. No correlation between TLR-2 and DC markers was detected in CD samples. A unique distribution of myeloid-DC markers characterized the CD ileum. Also, the presence of significant amounts of ileal CD1a+ cells may provide a relevant DC-mediated mechanism for antigen recognition in the pathogenesis of CD. © 2007 Springer Science+Business Media, LLC.
