Vibronic interactions in the visible and near-infrared spectra of C60− anions [PDF]
, 2008 Electron-phonon coupling is an important factor in understanding many properties of the C60 fullerides. However, there has been little success in quantifying the strength of the vibronic coupling in C60 ions, with considerable disagreement between ...

Coupling-Independent Capacitive Wireless Power Transfer Using Frequency Bifurcation
Energies, 2018 Capacitive wireless power transfer can be realized by mutually coupled capacitors operating at a common resonant frequency. An optimal load exists that maximizes either the efficiency or the power transfer to the load.

Characteristics of a 2-2 Piezoelectric Composite Transducer Made by Magnetic Force Assembly
Crystals, 2022 A wider operational bandwidth, a higher electromechanical coupling factor, and lower acoustic impedance are important requirements for ultrasound transducers for use across many applications. Conventional 2-2 piezoelectric composite transducers have been

The bacterial transcription repair coupling factor [PDF]
Current Opinion in Structural Biology, 2007 The widely conserved bacterial transcription repair coupling factor (TRCF) is a large, multidomain, superfamily 2 ATPase. It couples nucleotide excision repair with transcription by dislodging inactive RNA polymerase molecules stalled at template DNA lesions and increasing the rate at which the Uvr(A)BC excinuclease acts at these sites.

Axial Vector Current and Coupling of the Quark in the Instanton Model [PDF]
, 2002 We compute the axial vector current, form factor, and coupling for quarks in the instanton liquid model with two light flavors. Non-local current corrections are derived, as required by the effective 't Hooft interaction.

Light Mesons elm Form Factor and Running Coupling Effects [PDF]
, 1998 The pion and kaon electromagnetic form factors $F_{M}(Q^2)$ are calculated at the leading order of pQCD using the running coupling constant method. In computations dependence of the meson distribution amplitudes on the hard scale $Q^2$ is taken into ...
