Molecular identification and biological characterization of from domestic pigeons () in Guangdong, China.

Pigeon coccidiosis caused by spp. is an important veterinary disease with a significant economic impact on the pigeon industry. Preventive measures for in pigeons have been hampered by the lack of extensive genetic, morphological, and biological data on the oocysts.

The bound state in the continuum in flexible terahertz metasurfaces enabled sensitive biosensing.

The combination of a flexible device and novel electromagnetic resonances offers new dimensions to manipulate electromagnetic waves and promises new device functionalities. In this study, we experimentally demonstrate a flexible metasurface that can support the bound state in the continuum (BIC) in the terahertz regime. The metasurface consists of toroidal dipole resonant units on top of the flexible polyimide substrate, which can support a terahertz Friedrich-Wintgen BIC resonance, and the resonance characteristics can be tuned by changing the parameters of the coupling unit among two resonant modes.
