Ultraviolet graphene ultranarrow absorption engineered by lattice plasmon resonance.

We numerically demonstrate an ultraviolet graphene ultranarrow absorption in a hybrid graphene-metal structure. The full-width at half maximum of the absorption band being 9 nm in ultraviolet range is achieved based on the coupling of lattice plasmon resonances of the metallic nanostructure to the optical dissipation of graphene. The position, absorbance and linewidth of the hybridized narrow resonant mode tuned by controlling geometrical parameters and materials are systematically investigated.

Utility of Real-Time Quantitative Polymerase Chain Reaction in Detecting .

This study aimed to assess the value of real-time quantitative polymerase chain reaction (RT-qPCR) for the detection of (MTB). Samples from 192 patients with suspected MTB were examined by RT-qPCR and an improved Löwenstein-Jensen (L-J) culture method. To evaluate the diagnostic usefulness of RT-qPCR in detecting MTB, a receiver operating characteristic (ROC) curve for RT-qPCR was generated, and the area under the curve (AUC) as well as a cutoff value was calculated.
