TL;DR: Li et al. as discussed by the authors proposed a reversible Li-CO 2 battery system based on co-oxidization of the resulting carbon and Li 2 CO 3 using a Ru catalyst, which provides strong theoretical underpinning for developing flexible routes for both CO 2 fixation and energy storage.

TL;DR: In this article, the authors examined the detailed physics of the feedback mechanism by relativistic active galactic nucleus (AGN) jets interacting with a two-phase fractal interstellar medium (ISM) in the kpc-scale core of galaxies using 29 three-dimensional grid-based hydrodynamical simulations.
Abstract: We examine the detailed physics of the feedback mechanism by relativistic active galactic nucleus (AGN) jets interacting with a two-phase fractal interstellar medium (ISM) in the kpc-scale core of galaxies using 29 three-dimensional grid-based hydrodynamical simulations. The feedback efficiency, as measured by the amount of cloud dispersal generated by the jet-ISM interactions, is sensitive to the maximum size of clouds in the fractal cloud distribution but not to their volume filling factor. Feedback ceases to be efficient for Eddington ratios P jet/L edd 10?4, although systems with large cloud complexes 50 pc require jets of Eddington ratio in excess of 10?2 to disperse the clouds appreciably. Based on measurements of the bubble expansion rates in our simulations, we argue that sub-grid AGN prescriptions resulting in negative feedback in cosmological simulations without a multi-phase treatment of the ISM are good approximations if the volume filling factor of warm-phase material is less than 0.1 and the cloud complexes are smaller than ~25 pc. We find that the acceleration of the dense embedded clouds is provided by the ram pressure of the high-velocity flow through the porous channels of the warm phase, flow that has fully entrained the shocked hot-phase gas it has swept up, and is additionally mass loaded by ablated cloud material. This mechanism transfers 10% to 40% of the jet energy to the cold and warm gas, accelerating it within a few 10 to 100 Myr to velocities that match those observed in a range of high- and low-redshift radio galaxies hosting powerful radio jets.

TL;DR: In this paper, the Anderson tight binding model was considered and the exponential decay of the fractional moment of the Green function was shown to hold for complex energies near the energy where Anderson localization is expected.
Abstract: We consider the Anderson tight binding modelH=−Δ+V acting inl 2(Z d ) and its restrictionH Λ to finite hypercubes Λ⊂Z d . HereV={V x ;x∈Z d } is a random potential consisting of independent identically distributed random variables. Let {E j (Λ)} j be the eigenvalues ofH Λ, and let ξ j (Λ,E)=|Λ|(E j (Λ)−E),j≧1, be its rescaled eigenvalues. Then assuming that the exponential decay of the fractional moment of the Green function holds for complex energies nearE and that the density of statesn(E) exists atE, we shall prove that the random sequence {ξ j (Λ,E)} j , considered as a point process onR 1, converges weakly to the stationary Poisson point process with intensity measuren(E)dx as Λ gets large, thus extending the result of Molchanov proved for a one-dimensional continuum random Schrodinger operator. On the other hand, the exponential decay of the fractional moment of the Green function was established recently by Aizenman, Molchanov and Graf as a technical lemma for proving Anderson localization at large disorder or at extreme energy. Thus our result in this paper can be summarized as follows: near the energyE where Anderson localization is expected, there is no correlation between eigenvalues ofH Λ if Λ is large.
