A subwavelength-thick porous ribbon waveguide (PRW) has been experimentally demonstrated for sensing biological electrolytes in the terahertz (THz) regime. The transmission loss constant of the transverse-magnetic (TM) waveguide mode propagating on a PRW is used as the THz sensing signal and found t...

Investigating the coupled hydrodynamic and thermal wakes induced by underwater vehicles is vital for non-acoustic detection and environmental monitoring. Here, the standard SUBOFF model is simulated under eight operating conditions—speeds of 10, 15, and 20 kn; depths of 10, 20, and 30 m; and both wi...

Fano resonance results from interference between a background and a resonant scattering, which produces the asymmetrical lineshape. A cylindrical microcavity naturally possesses localized whispering gallery mode (WGM) and delocalized radiation mode, and a thin fiber taper can excite these two modes...

Tunable oscillating Fano spectra are demonstrated theoretically and experimentally in a fiber taper coupled conical microresonator for the first time. The oscillating Fano spectra are the modulated spectra of the resonant fields in the conical microresonator by a complex Fano parameter. Also the osc...

To construct the eukaryotic expression vector of pCEP4-CaBP-D28k, a pair of primers was designed according to chicken calbindin-D28k (CaBP-D28k) gene sequence published in GenBank. Chicken CaB P-D28k gene was amplified by RT-PCR from chicken intestine total RNA extracts and was cloned into eukaryoti...

A tightly coupled hybrid monocular visual SLAM system for unmanned underwater vehicles (UUVs) is introduced in this paper. Specifically, we propose a robust three-step hybrid tracking strategy. The feature-based method initially provides a rough pose estimate, then the direct method refines it, and...
