Vacuum-induced Autler-Townes splitting in a superconducting artificial atom

We experimentally study a vacuum-induced Autler-Townes doublet in a superconducting three-level artificial atom strongly coupled to a coplanar waveguide resonator and simultaneously to a transmission line. The Autler-Townes splitting is observed in the reflection spectrum from the three-level atom in a transition between the ground state and the second excited state when the transition between the two excited states is resonant with a resonator. By applying a driving field to the resonator, we observe a change in the regime of the Autler-Townes splitting from quantum (vacuum-induced) to classical (with many resonator photons). Furthermore, we show that the reflection of propagating microwaves in a transmission line could be controlled by different frequency single photons in a resonator.Comment: 5 pages, 3 figures+supplementary material

Group properties and invariant solutions of a sixth-order thin film equation in viscous fluid

Using group theoretical methods, we analyze the generalization of a one-dimensional sixth-order thin film equation which arises in considering the motion of a thin film of viscous fluid driven by an overlying elastic plate. The most general Lie group classification of point symmetries, its Lie algebra, and the equivalence group are obtained. Similar reductions are performed and invariant solutions are constructed. It is found that some similarity solutions are of great physical interest such as sink and source solutions, travelling-wave solutions, waiting-time solutions, and blow-up solutions.Comment: 8 page

Formulating project-level building information modeling evaluation framework from the perspectives of organizations: a review

This study identifies Building Information Modeling (BIM) benefits in the presentations of previous project participants and specialties. Based on recent data, a framework for evaluating the project-level BIM benefits from the perspectives of different stakeholders involved in the project is proposed. In order to maximize the benefits for each user or stakeholder, the functions and methods for implementing BIM on construction projects are explained. The results show that the advantages of implementing BIM in construction projects can be effectively evaluated by the proposed framework. Results presented herein provide documentation to improve the understanding of BIM benefits to all construction industry stakeholders

Dispersion, damping, and intensity of spin excitations in the single-layer (Bi,Pb)2_{2}(Sr,La)2_{2}CuO6+δ_{6+\delta} cuprate superconductor family

Using Cu-$L_3$ edge resonant inelastic x-ray scattering (RIXS) we measured the dispersion and damping of spin excitations (magnons and paramagnons) in the high-$T_\mathrm{c}$ superconductor (Bi,Pb)$_{2}$(Sr,La)$_{2}$CuO$_{6+\delta}$ (Bi2201), for a large doping range across the phase diagram ($0.03\lesssim p\lesssim0.21$). Selected measurements with full polarization analysis unambiguously demonstrate the spin-flip character of these excitations, even in the overdoped sample. We find that the undamped frequencies increase slightly with doping for all accessible momenta, while the damping grows rapidly, faster in the (0,0)$\rightarrow$(0.5,0.5) nodal direction than in the (0,0)$\rightarrow$(0.5,0) antinodal direction. We compare the experimental results to numerically exact determinant quantum Monte Carlo (DQMC) calculations that provide the spin dynamical structure factor $S(\textbf{Q},\omega)$ of the three-band Hubbard model. The theory reproduces well the momentum and doping dependence of the dispersions and spectral weights of magnetic excitations. These results provide compelling evidence that paramagnons, although increasingly damped, persist across the superconducting dome of the cuprate phase diagram; this implies that long range antiferromagnetic correlations are quickly washed away, while short range magnetic interactions are little affected by doping.Comment: 11 pages, 9 figure

Evidence for nodeless superconducting gap in NaFe1−x_{1-x}Cox_xAs from low-temperature thermal conductivity measurements

The thermal conductivity of optimally doped NaFe$_{0.972}$Co$_{0.028}$As ($T_c \sim$ 20 K) and overdoped NaFe$_{0.925}$Co$_{0.075}$As ($T_c \sim$ 11 K) single crystals were measured down to 50 mK. No residual linear term $\kappa_0/T$ is found in zero magnetic field for both compounds, which is an evidence for nodeless superconducting gap. Applying field up to $H$ = 9 T ($\approx H_{c2}/4$) does not noticeably increase $\kappa_0/T$ in NaFe$_{1.972}$Co$_{0.028}$As, which is consistent with multiple isotropic gaps with similar magnitudes. The $\kappa_0/T$ of overdoped NaFe$_{1.925}$Co$_{0.075}$As shows a relatively faster field dependence, indicating the increase of the ratio between the magnitudes of different gaps, or the enhancement of gap anisotropy upon increasing doping.Comment: 5 pages, 4 figure

A Randomized Trial of Two Print Interventions to Increase Colon Cancer Screening Among First-Degree Relatives

First-degree relatives (FDRs) of people diagnosed with colorectal cancer (CRC) have a two- to threefold increased risk of developing the same disease. Tailored print interventions based on behavior change theories have demonstrated considerable promise in facilitating health-promoting behaviors. This study compared the impact of two mailed print interventions on CRC screening outcomes among FDRs. Methods This randomized trial compared effects of two mailed print interventions – one tailored and one nontailored – on participation in CRC screening among FDRs of CRC survivors. Data collected via phone interviews from 140 FDRs at baseline, 1 week post-intervention, and 3 months post-intervention. Results At 3 months, both the tailored and nontailored interventions yielded modest but statistically insignificant increases in adherence to any CRC screening test (14% vs. 21%, respectively; p = 0.30). While there were no main effects for tailored versus nontailored interventions, there were significant interactions that showed that the tailored print intervention had significantly greater effects on forward stage movement for CRC screening depending on stage of adoption at baseline, race, and objective CRC risk. Receipt of the tailored intervention was 2.5 times more likely to move baseline precontemplators and contemplators forward in stage of adoption for colonoscopy (95% CI: 1.10–5.68) and was three times more likely to move Caucasians forward in stage of adoption for FOBT (95% CI: 1.00–9.07). In addition, the tailored intervention was 7.7 times more likely to move people at average risk forward in stage of adoption for colonoscopy (95% CI: 1.25–47.75). Conclusion The tailored print intervention was more effective at moving Caucasians, those in precontemplation and contemplation at baseline, and those at average risk forward in their stage of adoption for CRC screening. Practice implications Both tailored and nontailored print interventions showed moderate effects for increasing CRC screening participation. Tailored print interventions may be more effective for certain subgroups
