Nonparametric predictive inference for combined competing risks data (2014)
Journal Article
Coolen-Maturi, T., & Coolen, F. (2014). Nonparametric predictive inference for combined competing risks data. Reliability Engineering & System Safety, 126, 87-97. https://doi.org/10.1016/j.ress.2014.01.007

The nonparametric predictive inference (NPI) approach for competing risks data has recently been presented, in particular addressing the question due to which of the competing risks the next unit will fail, and also considering the effects of unobser...

Broken planar Skyrmions — statics and dynamics (2014)
Journal Article
Jennings, P., & Winyard, T. (2014). Broken planar Skyrmions — statics and dynamics. Journal of High Energy Physics, 2014(1), https://doi.org/10.1007/jhep01%282014%29122

The broken planar Skyrme model is a theory that breaks global O (3) symmetry to the dihedral group D N . It has been shown that the single soliton solution is formed of N constituent parts, named partons, that are topologically confined. The multisol...

Holographic entanglement and causal information in coherent states (2014)
Journal Article
Gentle, S. A., & Rangamani, M. (2014). Holographic entanglement and causal information in coherent states. Journal of High Energy Physics, 2014(1), https://doi.org/10.1007/jhep01%282014%29120

Scalar solitons in global AdS4 are holographically dual to coherent states carrying a non-trivial condensate of a scalar operator. We study the holographic information content of these states, focusing on a particular spatial region, by examining the...

The Spectrum of Light States in Large N Minimal Models (2014)
Journal Article
Gaberdiel, M., Gopakumar, R., & Rangamani, M. (2014). The Spectrum of Light States in Large N Minimal Models. Journal of High Energy Physics, 2014(1), https://doi.org/10.1007/jhep01%282014%29116

WN,k minimal models possess an interesting class of ‘light’ primaries which control much of the low energy density of states in the large N ’t Hooft limit. In this paper we conduct a detailed exploration of their distribution using a combination of n... Read More about The Spectrum of Light States in Large N Minimal Models.

Practical statistical methods for call centres with a case study addressing urgent medical care delivery (2014)
Journal Article
Wooff, D., & Stirling, S. (2015). Practical statistical methods for call centres with a case study addressing urgent medical care delivery. Annals of Operations Research, 233(1), 501-515. https://doi.org/10.1007/s10479-014-1529-2

Our interest is in forecasting for call centres, and in particular out-of-hours call centres (OOHCC) which deal with patient requests for medical advice outside normal working hours. Planning needs accurate forecasts of incoming call volumes. These v... Read More about Practical statistical methods for call centres with a case study addressing urgent medical care delivery.

The Sakai-Sugimoto soliton (2014)
Journal Article
Bolognesi, S., & Sutcliffe, P. (2014). The Sakai-Sugimoto soliton. Journal of High Energy Physics, 2014(1), Article 78. https://doi.org/10.1007/jhep01%282014%29078

The Sakai-Sugimoto model is the preeminent example of a string theory de- scription of holographic QCD, in which baryons correspond to topological solitons in the bulk. Here we investigate the validity of various approximations of the Sakai-Sugimoto... Read More about The Sakai-Sugimoto soliton.

Numerical and analytical tests of quasi-integrability in modified Sine-Gordon models (2014)
Journal Article
Ferreira, L., & Zakrzewski, W. (2014). Numerical and analytical tests of quasi-integrability in modified Sine-Gordon models. Journal of High Energy Physics, 2014(1), Article 058. https://doi.org/10.1007/jhep01%282014%29058

Following our attempts to define quasi-integrability in which we related this concept to a particular symmetry of the two-soliton function we check this condition in three classes of modified sine-Gordon models in (1 + 1) dimensions. We find that the... Read More about Numerical and analytical tests of quasi-integrability in modified Sine-Gordon models.

Monte Carlo Simulation of Geminate Pair Recombination Dynamics in Organic Photovoltaic Devices: Multi-Exponential, Field-Dependent Kinetics and Its Interpretation (2014)
Journal Article

Monte Carlo simulations are used to examine charge-transfer (CT) state recombination dynamics considering the effects of energetic disorder and bulk heterojunction morphology. Strongly biexponential recombination kinetics were observed, in agreement...

Platonic hyperbolic monopoles (2014)
Journal Article
Manton, N., & Sutcliffe, P. (2014). Platonic hyperbolic monopoles. Communications in Mathematical Physics, 325(3), 821-845. https://doi.org/10.1007/s00220-013-1864-1

We construct a number of explicit examples of hyperbolic monopoles, with various charges and often with some platonic symmetry. The fields are obtained from instanton data in R 4 that are invariant under a circle action, and in most cases the monopol... Read More about Platonic hyperbolic monopoles.

This paper addresses a long standing problem - to identify the chiral ring and moduli space (i.e. as an algebraic variety) on the Coulomb branch of an NN = 4 superconformal field theory in 2+1 dimensions. Previous techniques involved a computation of... Read More about Monopole operators and Hilbert series of Coulomb branches of 3d N = 4 gauge theories.
