Conformal field theories in six-dimensional twistor space (2012)
Journal Article
Mason, L., Reid-Edwards, R., & Taghavi-Chabert, A. (2012). Conformal field theories in six-dimensional twistor space. Journal of Geometry and Physics, 62(12), 2353-2375. https://doi.org/10.1016/j.geomphys.2012.08.001

This article gives a study of the higher-dimensional Penrose transform between conformally invariant massless fields on space–time and cohomology classes on twistor space, where twistor space is defined to be the space of projective pure spinors of t...

Exogenous and endogenous crashes as phase transitions in complex financial systems (2012)
Journal Article
Fry, J. (2012). Exogenous and endogenous crashes as phase transitions in complex financial systems. European Physical Journal B : Condensed Matter and Complex Systems, 85, Article 405. https://doi.org/10.1140/epjb/e2012-30234-8

In this paper we provide a unifying framework for a set of seemingly disparate models for exogenous and endogenous shocks in complex financial systems. Markets operate by balancing intrinsic levels of risk and return. This remains true even in the mi...

A note on oblique water entry (2012)
Journal Article
Moore, M., Howison, S., Ockendon, J., & Oliver, J. (2013). A note on oblique water entry. Journal of engineering mathematics, 81(1), 67-74. https://doi.org/10.1007/s10665-012-9570-0

A minor error in Howison et al. (J. Eng. Math. 48:321–337, 2004) obscured the fact that the points at which the free surface turns over in the solution of the Wagner model for the oblique impact of a two-dimensional body are directly related to the t...

Three-dimensional oblique water-entry problems at small deadrise angles (2012)
Journal Article
Moore, M., Howison, S., Ockendon, J., & Oliver, J. (2012). Three-dimensional oblique water-entry problems at small deadrise angles. Journal of Fluid Mechanics, 711, 259-280. https://doi.org/10.1017/jfm.2012.391

This paper extends Wagner theory for the ideal, incompressible normal impact of rigid bodies that are nearly parallel to the surface of a liquid half-space. The impactors considered are three-dimensional and have an oblique impact velocity. A formula... Read More about Three-dimensional oblique water-entry problems at small deadrise angles.

Risk management and Basel-Accord-implementation in Pakistan (2012)
Journal Article
Masood, O., & Fry, J. (2012). Risk management and Basel-Accord-implementation in Pakistan. Journal of financial regulation and compliance, 20(3), 293-306. https://doi.org/10.1108/13581981211237981

Purpose Recent events demonstrate that problems in the banking system pose a significant threat to the health of the global economy. Despite several shortcomings the Basel Accord thus emerges as an attempt to protect banking systems. The purpose of... Read More about Risk management and Basel-Accord-implementation in Pakistan.

Perturbative behavior of a vortex in a trapped Bose-Einstein condensate (2012)
Journal Article
Martin, A. M., Koens, L., & Martin, A. M. (2012). Perturbative behavior of a vortex in a trapped Bose-Einstein condensate. Physical review. A, 86(1), Article 013605. https://doi.org/10.1103/PhysRevA.86.013605

We derive a set of equations that describes the shape and behavior of a single perturbed vortex line in a Bose-Einstein condensate. Through the use of a matched asymptotic expansion and a unique coordinate transform, a relation for a vortex's velocit...
