Energy Spectrum of quasigeostrophic turbulence.
Physical review letters, 2002Co-Authors: Peter ConstantinAbstract:We consider the Energy Spectrum of a quasigeostrophic model of forced, rotating turbulent flow. We provide a rigorous a priori bound $E(k)\ensuremath{\le}C{k}^{\ensuremath{-}2}$ valid for wave numbers that are smaller than a wave number associated with the forcing injection scale. This upper bound separates this Spectrum from the Kolmogorov-Kraichnan ${k}^{\ensuremath{-}\frac{5}{3}}$ Energy Spectrum that is expected in a two-dimensional Navier-Stokes inverse cascade. Our bound provides theoretical support for the ${k}^{\ensuremath{-}2}$ Spectrum observed in recent experiments.

Energy Spectrum of a nonstationary ensemble of pulses.
Optics letters, 2004Co-Authors: Sergey A. Ponomarenko, Govind P. Agrawal, Emil WolfAbstract:We introduce a new definition of the Energy Spectrum of a nonstationary ensemble of pulses that reduces to the usual ones in the limit of statistically stationary ensembles of signals and of fully temporarily coherent ensembles.

branching fraction and photon Energy Spectrum for b sγ
Physical Review Letters, 2001Co-Authors: Shuai Chen, J W Hinson, J Lee, D H Miller, V Pavlunin, E I Shibata, I P J Shipsey, D Croninhennessy, A L Lyon, E H ThorndikeAbstract:We have measured the branching fraction and photon Energy Spectrum for the radiative penguin process b-->s gamma. We find Beta(b-->s gamma) = (3.21+/-0.43+/-0.27(+0.18)(-0.10))x10(-4), where the errors are statistical, systematic, and from theory corrections. We obtain first and second moments of the photon Energy Spectrum above 2.0 GeV, = 2.346+/-0.032+/-0.011 GeV, and - (2) = 0.0226+/-0.0066+/-0.0020 GeV(2), where the errors are statistical and systematic. From the first moment, we obtain (in the modified minimal subtraction renormalization scheme, to order 1/M(3)(B) and beta(0)alpha(2)(s)) the heavy quark effective theory parameter Lambda = 0.35+/-0.08+/-0.10 GeV.
