Highly efficient optical power transfer to whispering-gallery modes by use of a symmetrical dual-coupling configuration [PDF]
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.

Measurement of streaming potential coupling coefficient in sandstones saturated with natural and artificial brines at high selenity [PDF]
We report experimental measurements of the streaming potential coupling coefficient in sandstones saturated with NaCl-dominated artificial and natural brines up to 5.5 M (321.4 g L−1 of NaCl; electrical conductivity of 23 S m−1).

Coherent quantum transport in disordered systems: A unified polaron treatment of hopping and band-like transport [PDF]
Quantum transport in disordered systems is studied using a polaron-based master equation. The polaron approach is capable of bridging the results from the coherent band-like transport regime governed by the Redfield equation to incoherent hopping ...

Resonant Mechanism for a Long-Distance Wireless Power Transfer Using Class E PA and GaN HEMT
This paper presents a study on long-distance wireless power transfer (WPT), which formulates the voltage gain in terms of the coupling coefficient between the power transmitting unit (PTU) and the power receiving unit (PRU) coils.

Coupling coefficients of combline resonators [PDF]
Bandpass filters require elements that behave as series or parallel resonant circuits. In this paper, we discuss a variety of couplings between combline resonators in bandpass filter applications. Coupling coefficient used in filter realizations has been precisely calculated.

Endogenous driving and synchronization in cardiac and uterine virtual tissues: bifurcations and local coupling [PDF]
Cardiac and uterine muscle cells and tissue can be either autorhythmic or excitable. These behaviours exchange stability at bifurcations produced by changes in parameters, which if spatially localized can produce an ectopic pacemaking focus.
