A Simplified Coupling Power Model of Single Mode Fiber Fusion at Coupling Length [PDF]

open access: yes2009 Third Asia International Conference on Modelling & Simulation, 2009
Fabrications of single mode fiber coupling by heating fibers on a flame are very common and popular. However, controlling the output power of fiber coupling process is neither easy nor similar. Power losses occur at the coupling length due to geometrical change of the fibers after fusion.

Coupling-length trimming by metal loading in optical coupled-waveguides

Optical and Quantum Electronics, 1981
A simple method for adjusting light coupling between two waveguides is presented. The method involves trimming the interaction length by loading a metal film on to one of the coupled-waveguides. It is effective only for the TM mode, and trimming can be achieved very simply.

Length Analyses of Mammalian G-protein-coupled Receptors

Journal of Theoretical Biology, 2001
G-protein-coupled receptors (GPCRs) play a crucial role in mediating effects of extracellular messengers in a wide variety of biological systems, comprising the largest gene superfamily at least in mammals. Mammalian GPCRs are broadly classified into three families based on pharmacological properties and sequence similarities.

On the performance of fixed-length spatially coupled LDPC code

2016 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting (BMSB), 2016
This paper evaluates the rate loss of fixed-length spatially-coupled low-density parity-check (SC-LDPC) code compared to the asymptotic performance of such code. In previous works, SC-LDPC with sufficient length of codeword shows excellent asymptotic performance and attracts a lot of attentions.

Extended Length Heterobifunctional Coupling Agents for Protein Conjugations

Bioconjugate Chemistry, 1996
A series of extended length heterobifunctional coupling agents is described. The successive aminocaproic acid homologation of succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate, a known 9-atom long maleimide active ester linker, yielded 16-, 23-, and 30-atom long maleimide active ester homologues. The performance study of these coupling agents
