Engineering luminopsins with improved coupling efficiencies
Neurophotonics, 2023 ABSTRACTSignificanceLuminopsins (LMOs) are bioluminescent-optogenetic tools with a luciferase fused to an opsin that allow bimodal control of neurons by providing both optogenetic and chemogenetic access. Determining which design features contribute to the efficacy of LMOs will be beneficial for further improving LMOs for use in research.AimWe ...

Efficient termination of spatially-coupled codes [PDF]
2012 IEEE Information Theory Workshop, 2012 Spatially-coupled low-density parity-check codes attract much attention due to their capacity-achieving performance and a memory-efficient sliding-window decoding algorithm. On the other hand, the encoder needs to solve large linear equations to terminate the encoding process. In this paper, we propose modified spatially-coupled codes.

Graphene–Coupled Highly Efficient THz Photomixer
2023 48th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2023 A novel THz photomixer detector based on interdigitated multilayer graphene (MLG) on low-temperature-grown (LTG) GaAs is demonstrated. It exhibits an enhanced performance as compared with conventional LTG GaAs photomixers with metallic finger contacts.

Coupling efficiency of secondary active transporters [PDF]
Current Opinion in Biotechnology, 2019 Secondary active transporters are fundamental to a myriad of biological processes. They use the electrochemical gradient of one solute to drive transport of another solute against its concentration gradient. Central to this mechanism is that the transport of one does not occur in the absence of the other. However, like in most of biology, imperfections

Stochastic coupled cluster theory: Efficient sampling of the coupled cluster expansion [PDF]
The Journal of Chemical Physics, 2017 We consider the sampling of the coupled cluster expansion within stochastic coupled cluster theory. Observing the limitations of previous approaches due to the inherently non-linear behavior of a coupled cluster wavefunction representation, we propose new approaches based on an intuitive, well-defined condition for sampling weights and on sampling the ...

Highly efficient optical power transfer to whispering-gallery modes by use of a symmetrical dual-coupling configuration [PDF]
, 2000 We report that greater than 99.8% optical power transfer to whispering-gallery modes was achieved in fused-silica microspheres by use of a dual-tapered-fiber coupling method.

Efficient Photonic Crystal Cavity-Waveguide Couplers [PDF]
, 2006 Coupling of photonic crystal (PC) linear three-hole defect cavities (L3) to PC waveguides is theoretically and experimentally investigated. The systems are designed to increase the overlap between the evanescent cavity field and the waveguide mode, and ...
