We study the horizon absorption of gravitational waves in coalescing, circularized, nonspinning blackhole binaries. The horizon-absorbed fluxes of a binary with a large mass ratio (q 1⁄4 1000) obtained by numerical perturbative simulations are compared with an analytical, effective-one-body (EOB) resummed expression recently proposed. The perturbative method employs an analytical, linear in the...

We study anti-de Sitter black holes and evaluate different thermodynamic quantities in the EinsteinGauss-Bonnet and the general R2 gravity theories. We examine the possibility of Hawking-Page type thermal phase transitions between AdS black hole and thermal anti-de Sitter space in such theories. In Einstein theory with a possible cosmological term, one observes a Hawking-Page phase transition o...

We analyze several ways of conducting long-horizon regressions, taken from the empirical literature. Asymptotic arguments are used to show that, in all cases, the t-statistics do not converge to well-de…ned distributions, thus explaining the tendency of long-horizon regressions to …nd ’signi…cant’ results, where previous short-term approaches have failed. Moreover, in some cases, the ordinary l...

A model predictive control (MPC) strategy is developed to determine the optimal solution of the short-term refinery production planning problem. The main objective of the proposed algorithm is to maximize the total profit and to minimize the costs regarding the refinery process over a planning horizon. The refinery planning problem is solved in discrete time over a pre-determined prediction hor...

We present three experiments on horizon estimation. In Experiment 1 we verify the human ability to estimate the horizon in static images from only visual input. Estimates are given without time constraints with emphasis on precision. The resulting estimates are used as baseline to evaluate horizon estimates from early visual processes. Stimuli are presented for only 153 ms and then masked to pu...

We characterise the subgame perfect equilibrium of a di¤erential market game with hyperbolic inverse demand where …rms are quantity-setters and accumulate capacity over time à la Ramsey. The related Hamilton-JacobiBellman are solved in closed form both on in…nite and on …nite horizon setups and the optimal strategies are determined. Then, we analyse the feasibility of horizontal mergers in both...

This paper analyzes the dynamic properties of portfolios that sustain Pareto optimal allocations. We consider an in…nite horizon stochastic endowment economy where the actual process of the states of nature consists in i.i.d draws from a common probability distribution. The economy is populated by many Bayesian agents with heterogeneous prior beliefs over the stochastic process of the states of...

This paper studies the interpretation of physics near a Schwarzschild black hole. A scenario for creation and growth is proposed that avoids the conundrum of information loss. In this picture the horizon recedes as it is approached and has no physical reality. Radiation is likely to occur, but it cannot be predicted.
