Roughening Transition in a One-Dimensional Growth Process

Uri Alon, Martin Evans, Haye Hinrichsen +1

A class of nonequilibrium models with short-range interactions and sequential updates is presented. The models describe one dimensional growth processes which display a roughening…

Non-perturbative renormalization of lattice QCD at all scales

Karl Jansen, Chuan Liu, Martin Luescher +5

A general strategy to solve the non-perturbative renormalization problem in lattice QCD, using finite-size techniques and numerical simulations, is described. As an illustration we…

The Landshoff-Nachtmann Pomeron on the Lattice

D. S. Henty, C. Parrinello, D. G. Richards

We investigate the Landshoff-Nachtmann two-gluon-exchange model of the Pomeron using gluon propagators computed in the Landau gauge within quenched lattice QCD calculations. We fir…

A Next-to-Leading Determination of the Singlet Axial Charge and the Polarized Gluon Content of the Nucleon

R. D. Ball, S. Forte, G. Ridolfi

We perform a full next-to-leading analysis of the the available experimental data on the polarized structure function g_1 of the nucleon, and give a precise determination of its si…

Statistics of Small-N Simulations

Douglas C. Heggie

We first review the reasons for carrying out statistical analysis of results from large numbers of N-body simulations, including a summary of previous work. Then we describe some r…

Dark Matter in Globular Clusters

Douglas C. Heggie, Piet Hut

We first review reasons why dark matter is an interesting issue in connection with star clusters. Next we consider to what extent the presence of dark matter is consistent with the…

Letting the Cat out of the Bag: Generation for Shake-and-Bake MT

Chris Brew

Describes an algorithm for the generation phase of a Shake-and-Bake Machine Translation system. Since the problem is NP-complete, it is unlikely that the algorithm will be efficien…

The scalar glueball from a tadpole-improved action

Colin Morningstar, Mike Peardon

The scalar glueball mass and the string tension are computed in lattice SU(3) gauge theory with the aim of establishing the effectiveness of the improved action approach in removin…

Tuning the generalized Hybrid Monte Carlo algorithm

A D Kennedy, Robert Edwards, Hidetoshi Mino +1

We discuss the analytic computation of autocorrelation functions for the generalized Hybrid Monte Carlo algorithm applied to free field theory and compare the results with numerica…

A Labelled Analytic Theorem Proving Environment for Categorial Grammar

Saturnino F. Luz-Filho, Patrick Sturt

We present a system for the investigation of computational properties of categorial grammar parsing based on a labelled analytic tableaux theorem prover. This proof method allows u…

Lattice Study of the Decay B^0-bar -> rho^+ l^- nu_l-bar: Model-Independent Determination of |V_{ub}|

UKQCD Collaboration, J M Flynn, J Nieves +9

We present results of a lattice computation of the vector and axial-vector current matrix elements relevant for the semileptonic decay B^0-bar -> rho^+ l^- nu_l-bar. The computatio…

The small-scale clustering power spectrum and relativistic decays

S. J. McNally, J. A. Peacock

We present constraints on decaying-particle models in which an enhanced relativistic density allows an Cold Dark Matter universe to be reconciled with acceptable values for t…

The Effect of Encounters on the Eccentricity of Binaries in Clusters

Douglas C. Heggie, Frederic A. Rasio

We derive analytical expressions for the change in the orbital eccentricity of a binary following a distant encounter with a third star on a hyperbolic or parabolic orbit. To estab…

Semantic Ambiguity and Perceived Ambiguity

Massimo Poesio

I explore some of the issues that arise when trying to establish a connection between the underspecification hypothesis pursued in the NLP literature and work on ambiguity in seman…

Exploring the role of Punctuation in Parsing Natural Text

Bernard Jones

Few, if any, current NLP systems make any significant use of punctuation. Intuitively, a treatment of punctuation seems necessary to the analysis and production of text. Whilst thi…

Generating efficient belief models for task-oriented dialogues

Jasper Taylor

We have shown that belief modelling for dialogue can be simplified if the assumption is made that the participants are cooperating, i.e., they are not committed to any goals requir…
