Fourier path integrals, partial averaging, and the polaron problem
(1990)We evaluate the Fourier path integral for an optical polaron by the method of partial averaging. Higher Fourier coefficients are taken into account by averaging with Feynmans trial action, whereas the first N coefficients ...

Fourier transform infrared (FTIR) and step-scan time-resolved FTIR spectroscopies reveal a unique active site in cytochrome caa3 oxidase from Thermus thermophilus
(2002)Fourier transform infrared (FTIR) and step-scan time-resolved FTIR difference spectra are reported for the [carbonmonoxy]cytochrome caa3 from Thermus thermophilus. A major C-O mode of heme a3 at 1958 cm-1 and two minor ...

Fourier transform infrared evidence for a ferric six-coordinate nitrosylheme b3 complex of cytochrome cbb3 oxidase from Pseudomonas stutzeri at ambient temperature
(2002)We report the first vibrational study of NO bound to an oxidized heme-copper oxidase. Cytochrome cbb3 oxidase from P. stutzeri reduces both O2 and NO to H2O and N2O, respectively. The ferric nitrosyl complex of cbb3 exhibits ...

FOXO3a is broadly neuroprotective in vitro and in vivo against insults implicated in motor neuron diseases
(2009)Aging is a risk factor for the development of adult-onset neurodegenerative diseases. Although some of the molecular pathways regulating longevity and stress resistance in lower organisms are defined (i.e., those activating ...

Förster resonant energy transfer from an inorganic quantum well to a molecular material: Unexplored aspects, losses, and implications to applications
(2015)A systematic investigation of Förster resonant energy transfer (FRET) is reported within a hybrid prototype structure based on nitride single quantum well (SQW) donors and light emitting polymer acceptors. Self-consistent ...

Fractal behaviour in the O(3) model
(1995)We study domain formation in the two-dimensional O(3) model near criticality. The fractal dimension of these domains is determined with good statistical accuracy. © 1995.

Fractional charges for the non-Abelian fermion-monopole system
(1985)The Dirac equation is studied in the background of a non-Abelian magnetic monopole. The inclusion of chirally rotated scalar and isotriplet masses induces a dependence of the charge and fermion number densities on the ...

Fracton superconductivity in quasicrystals - A theoretical possibility suggested by experiment
(1999)Scattering of electrons due to fractons can result in a resistivity that decreases with temperature. Such a behavior also appears in real quasicrystalline materials. If this is then attributed to effective fracton scattering, ...
