Exploring the physical basis of solar cycle predictions: Flux transport dynamics and persistence of memory in advection versus diffusion-dominated solar convection zones (2008)
Journal Article
Yeates, A., Nandy, D., & Mackay, D. (2008). Exploring the physical basis of solar cycle predictions: Flux transport dynamics and persistence of memory in advection versus diffusion-dominated solar convection zones. Astrophysical Journal, 673(1), 544-556. https://doi.org/10.1086/524352

The predictability, or lack thereof, of the solar cycle is governed by numerous separate physical processes that act in unison in the interior of the Sun. Magnetic flux transport and the finite time delay that it introduces, specifically in the so-ca...

Jorgensen's inequality for non-Archimedean metric spaces (2008)
Presentation / Conference Contribution
Armitage, J., & Parker, J. R. (2006, September). Jorgensen's inequality for non-Archimedean metric spaces. Presented at Geometry and dynamics of groups and spaces : in memory of Alexander Reznikov., Bonn, Germany

Jørgensen’s inequality gives a necessary condition for a non-elementary group of Möbius transformations to be discrete. In this paper we generalise this to the case of groups of Möbius transformations of a non-Archimedean metric space. As an applicat...

Form factors of branch-point twist fields in quantum integrable models and entanglement entropy (2008)
Journal Article
Cardy, J. L., Castro Alvaredo, O. C., & Doyon, B. (2008). Form factors of branch-point twist fields in quantum integrable models and entanglement entropy. Journal of Statistical Physics, 130(1), 129-168. https://doi.org/10.1007/s10955-007-9422-x

In this paper we compute the leading correction to the bipartite entanglement entropy at large sub-system size, in integrable quantum field theories with diagonal scattering matrices. We find a remarkably universal result, depending only on the parti... Read More about Form factors of branch-point twist fields in quantum integrable models and entanglement entropy.

Modelling the global solar corona II: Coronal evolution and filament chirality comparison (2008)
Journal Article
Yeates, A., Mackay, D., & van Ballegooijen, A. (2008). Modelling the global solar corona II: Coronal evolution and filament chirality comparison. Solar Physics, 247(1), 103-121. https://doi.org/10.1007/s11207-007-9097-0

This paper considers the hemispheric pattern of solar filaments using newly developed simulations of the real photospheric and 3D coronal magnetic fields over a six-month period, on a global scale. The magnetic field direction in the simulation is co... Read More about Modelling the global solar corona II: Coronal evolution and filament chirality comparison.

Asymptotic behaviour of randomly reflecting billiards in unbounded tubular domains (2008)
Journal Article
Menshikov, M., Vachkovskaia, M., & Wade, A. (2008). Asymptotic behaviour of randomly reflecting billiards in unbounded tubular domains. Journal of Statistical Physics, 132(6), 1097-1133. https://doi.org/10.1007/s10955-008-9578-z

We study stochastic billiards in infinite planar domains with curvilinear boundaries: that is, piecewise deterministic motion with randomness introduced via random reflections at the domain boundary. Physical motivation for the process originates wit... Read More about Asymptotic behaviour of randomly reflecting billiards in unbounded tubular domains.

Variations in posttonsillectomy haemorrhage rates are scale invariant (2008)
Journal Article
Phillips, J., Ward, T., & Montgomery, P. (2008). Variations in posttonsillectomy haemorrhage rates are scale invariant. The Laryngoscope, 118(6), 1096-1098. https://doi.org/10.1097/mlg.0b013e3181672277

Background: Scale invariance is a property of scientific laws or objects that change in a prescribed fashion if measurements are scaled, and is often represented by a power-law relationship. Power laws suggest that events of a large magnitude will be... Read More about Variations in posttonsillectomy haemorrhage rates are scale invariant.
