A 23-year-old male patient was anesthetized with fentanyl and propofol. Thirty minutes after inducing anesthesia, unilateral mydriasis was detected. The duration of surgery was shortened for prompt evaluation of the pupils. At the end of the operation neither vision ...

We report on the design and fabrication of a dual-wavelength switchable quantum cascade laser (QCL) by optimizing homogeneous active region combining superposed distributed feedback gratings. Coaxial, single-mode emissions at two different wavelengths were achieved only through adjusting bias voltage. Room temperature continuous-wave operation with output powers above 30 mW 75 was realized for ...

Lhasa is a “solar city” with high altitude, located in a cold zone in China. Due to the lack of mineral energy sources and the fragility of its ecological environment, solar heating technology is the first choice to satisfy the demand of indoor thermal comfort for building heating. In this study, an accurate solar heating system in Lhasa was investigated under the simultaneous charging and disc...
