    In the eyes of William Lloyd Garrison, Abraham Lincoln stood waffling on the issue of slavery in the early days of December 1862. To be quite fair, in Garrison\u27s eyes nearly anyone aside from William Lloyd Garrison stood waffling on the issue of slavery most of the time. [excerpt

    The Correlated Lloyd model: exact solution

    Full text link
    Exactly solvable model of disordered system representing the generalized Lloyd model with correlated random potential is described. It is shown, that for the model under consideration, the averaged Green's function does not depend on random potential correlation radius and, similarly to the classical Lloyd model, has the form of Green's function of a crystal system, with energy argument supplied by an imaginary part which depends on degree of disorder

    Testing Holographic Conjectures of Complexity with Born-Infeld Black Holes

    Full text link
    In this paper, we use Born-Infeld black holes to test two recent holographic conjectures of complexity, the "Complexity = Action" (CA) duality and "Complexity = Volume 2.0" (CV) duality. The complexity of a boundary state is identified with the action of the Wheeler-deWitt patch in CA duality, while this complexity is identified with the spacetime volume of the WdW patch in CV duality. In particular, we check whether the Born-Infeld black holes violate the Lloyd bound: C˙2π[(MQΦ)(MQΦ)gs]\mathcal{\dot{C}\leq}\frac{2}{\pi\hbar}\left[ \left( M-Q\Phi\right) -\left( M-Q\Phi\right) _{\text{gs}}\right] , where gs stands for the ground state for a given electrostatic potential. We find that the ground states are either some extremal black hole or regular spacetime with nonvanishing charges. Near extremality, the Lloyd bound is violated in both dualities. Near the charged regular spacetime, this bound is satisfied in CV duality but violated in CA duality. When moving away from the ground state on a constant potential curve, the Lloyd bound tend to be saturated from below in CA duality, while C˙\mathcal{\dot{C}} is π/2\pi/2 times as large as the Lloyd bound in CV duality.Comment: 25 papes, 15 figure

    To establish whether there are differences in performance between 757 (Lloyd Maunders) birds and the Maurice Millard 257 those currently used within the Sheepdrove system

    Sheepdrove Organic Farm wanted to know whether the performance of the Lloyd Maunders (757) birds would differ from that of their current breed the Maurice Millard (257) and whether chicks sourced from an organic parent flock would perform differently to those from a conventional parent flock. An experiment was undertaken using two different sources of day old chicks, 1000 day old Maurice Millard (257) and 1000 day old Lloyd Maunders (757). These chicks were then put through the Sheepdrove (SOF) organic production system and 30 random birds were weighed every week until depletion, at 11 weeks
