Statistics of Weak Gravitational Lensing in Cold Dark Matter Models; Magnification Bias on Quasar Luminosity Functions [PDF]
, 1999 We compute statistical properties of weak gravitational lensing by large-scale structure in three Cold Dark Matter models. We use a P$^3$M $N$-body code to simulate the formation and evolution of large-scale structure in the universe.

Further Precise Determinations of $\alpha_s$ from Lattice QCD
, 1997 We present a new determination of the strong coupling constant from lattice QCD simulations. We use four different short-distance quantities to obtain the coupling, three different (infrared) meson splittings to tune the simulation parameters, and a wide

Aisthesis, 2011 Es evidente que hoy en día adquiere una importancia singular la visualización de imágenes y también la forma en que ellas -querámoslo o no- impactan nuestra retina, lo cual supone por parte del espectador unos criterios interpretativos que muchas veces ...

Why charges go to the surface: a generalized Thomson problem
, 2003 We study a generalization of a Thomson problem of n particles confined to a sphere and interacting by a 1/r^g potential. It is found that for g \le 1 the electrostatic repulsion expels all the charges to the surface of the sphere.

David Hockney’s Early Etchings: Going Transatlantic and Being British
Tate Papers, 2017 David Hockney’s early autobiographical prints, My Bonnie Lies Over the Ocean 1961 and the series A Rake’s Progress 1961–3, are examined in relation to contemporary developments in American art and literature, the artist’s affinities with his British ...

The Baltic International Yearbook of Cognition, Logic and Communication, 2010 Ascriptions of belief and other doxastic propositional attitudes are commonly interpreted as quantifying over a set of possible worlds constituting doxastic alternatives for the belief experiencer.

A New Technique for Measuring the Strangemess Content of the Proton on the Lattice
, 1992 A new technique for computing the strangeness content of the proton on the lattice is described. It is applied to the calculation of the strange quark contribution to the proton's spin, specifically to the evaluation of the proton matrix element of the ...

Superconducting linear actuator [PDF]
Special actuators are needed to control the orientation of large structures in space-based precision pointing systems. Electromagnetic actuators that presently exist are too large in size and their bandwidth is too low.

How to mesh up Ewald sums (II): An accurate error estimate for the P3M algorithm
, 1998 We construct an accurate estimate for the root mean square force error of the particle-particle-particle-mesh (P3M) algorithm by extending a single particle pair error measure which has been given by Hockney and Eastwood.

Solution of partial differential equations on vector and parallel computers [PDF]
The present status of numerical methods for partial differential equations on vector and parallel computers was reviewed. The relevant aspects of these computers are discussed and a brief review of their development is included, with particular attention
