Background and Aims Hepatocellular carcinoma (HCC) incidence is increasing at differential rates depending on race. We aimed to identify associations between race and survival after HCC diagnosis in a diverse American population. Methods Using the cancer registry from Sylvester Comprehensive Cancer Center, University of Miami and Jackson Memorial Hospitals, we performed retrospective analysis of...
We use periodic waveguide to achieve single-mode backward-wave that supports long-range optical pulling forces. We explore the ambiguity of backward-waves in the periodic system and eliminate aliased backward-waves that only generates pushing forces.
We numerically demonstrate optical force between graphene sheets can be enhanced by 50× at terahertz from the extraordinary wavelength reduction of quasi-TEM modes. Unlike step-index waveguides, the force is attractive irrespective of the waveguide dispersion.
We provide a new scheme of photonic pulling force in one-way waveguides. Objects of arbitrary shape and dielectric properties can be pulled all the way to the light source, regardless of waveguide geometry.
