Underwater depth measurements and point cloud images can be used for robotic navigation and haptic feedback. Structured Light and Time of Flight (ToF) depth camera systems were tested to demonstrate depth measurements and point cloud imaging underwater. A commercial ToF depth camera was modified to include a movable external light source. Images from depth measurements and constructed point cloud...
This paper derives the new equations for the full extraction method in retrieving effective refractive indices, impedances, and material properties, such as permittivity (ε) and permeability (μ), of an asymmetric metamaterial, meaning that the metamaterial slab is asymmetric along the wave propagation direction, or the slab is not mounted exactly in the middle of two measurement ports. Traditionally,...
Our earlier studies indicated the high expression of a UV-damaged-DNA binding activity in zebrafish (Danio rerio) embryos at 12 h postfertilization (hpf). Two 30- to 35-kDa polypeptides homologous to the N-terminal lipovitellin 1 (Lv1) domain of the 150-kDa zebrafish vitellogenin 1 (zfVg1) were identified as the damage recognition factors in zebrafish extracts, and the metal-chelating agent 1,10-phenanthroline...
