Sigma coupling to photons: hidden scalar in gamma gamma $\to$ pi0 pi0 (2006)
Journal Article
Pennington, M. (2006). Sigma coupling to photons: hidden scalar in gamma gamma $\to$ pi0 pi0. Physical Review Letters, 97(1), https://doi.org/10.1103/physrevlett.97.011601

There has long been speculation about the nature of the resonance. For three decades Jaffe has argued for a tetraquark composition, while others have claimed it is largely a glueball. A key pointer to its nature is its coupling to two photons. Conseq... Read More about Sigma coupling to photons: hidden scalar in gamma gamma $\to$ pi0 pi0.

On nonparametric predictive inference and abjective Bayesianism (2006)
Journal Article
Coolen, F. (2006). On nonparametric predictive inference and abjective Bayesianism. Journal of Logic, Language and Information, 15(1-2), 21-47. https://doi.org/10.1007/s10849-005-9005-7

This paper consists of three main parts. First, we give an introduction to Hill’s assumption A (n) and to theory of interval probability, and an overview of recently developed theory and methods for nonparametric predictive inference (NPI), which is...

Analyzing Irish suicide rates with mixture models (2006)
Presentation / Conference Contribution
Sofroniou, N., Einbeck, J., Hinde, J., & Newell, J. (2006, July). Analyzing Irish suicide rates with mixture models. Presented at 21th International Workshop on Statistical Modelling., Galway, Ireland

In the analysis of morbidity and mortality data, variance component models are commonly used to provide an improvement in the estimation of rates for small regions which typically show large variability. This article investigates Irish suicide data u... Read More about Analyzing Irish suicide rates with mixture models.

Open sets of maximal dimension in complex hyperbolic quasi-Fuchsian space (2006)
Journal Article
Parker, J. R., & Platis, I. D. (2006). Open sets of maximal dimension in complex hyperbolic quasi-Fuchsian space. Journal of Differential Geometry, 73(2), 319-350

Let pi(1), be the fundamental group of a closed surface Sigma of genus g > 1. One of the fundamental problems in complex hyperbolic geometry is to find all discrete, faithful, geometrically finite and purely loxodromic representations of pi(1) into S...

Electron self-trapping on a nano-circle. (2006)
Journal Article
Brizhik, L., Eremko, A., Piette, B., & Zakrzewski, W. (2006). Electron self-trapping on a nano-circle. Physica D: Nonlinear Phenomena, 218(1), 36-55. https://doi.org/10.1016/j.physd.2006.04.010

We study the self-trapping of quasiparticles (electrons, holes or excitons) in a molecular chain with the structure of a ring, taking into account the electron–phonon interaction and the radial and tangential deformations of the chain. A discrete sys... Read More about Electron self-trapping on a nano-circle..

A note on NPML estimation for exponential family regression models with unspecified dispersion parameter (2006)
Journal Article
Einbeck, J., & Hinde, J. (2006). A note on NPML estimation for exponential family regression models with unspecified dispersion parameter. Austrian Journal of Statistics, 35(2&3), 233-243

Nonparametric maximum likelihood (NPML) estimation for exponential families with unspecified dispersion parameter \phi suffers from computational instability, which can lead to highly fluctuating EM trajectories and suboptimal solutions, in particula...

The destabilizing effect of boundary slip on Benard convection (2006)
Journal Article
Webber, M. (2006). The destabilizing effect of boundary slip on Benard convection. Mathematical Methods in the Applied Sciences, 29(7), 819-838. https://doi.org/10.1002/mma.711

We investigate the influence of slip boundary conditions on the onset of Bénard convection in an infinite fluid layer. It is shown that the critical Rayleigh number is a decreasing function of the slip length, and therefore boundary slip is seen to h...

An atavistic Lie algebra (2006)
Journal Article
Fairlie, D. B., & Zachos, C. K. (2006). An atavistic Lie algebra. Physics Letters B, 637(1-2), 123-127. https://doi.org/10.1016/j.physletb.2006.04.013

An infinite-dimensional Lie Algebra is proposed which includes, in its subalgebra and limits, most Lie Algebras routinely utilised in physics. It relies on the finite oscillator Lie group and appears applicable to twisted noncommutative QFT and CFT.
