Dynamic prediction modeling approaches for cardiac surgery (2013)
Journal Article
Hickey, G., Grant, S., Caiado, C., Kendall, S., Dunning, J., Poullis, M., …Bridgewater, B. (2013). Dynamic prediction modeling approaches for cardiac surgery. Circulation: Cardiovascular Quality and Outcomes, 6(6), 649-658. https://doi.org/10.1161/circoutcomes.111.000012

Background: The calibration of several cardiac clinical prediction models has deteriorated over time. We compare different model fitting approaches for in-hospital mortality after cardiac surgery that adjust for cross-sectional case mix in a heteroge...

Mapping Dirac gaugino masses (2013)
Journal Article
Abel, S., & Busbridge, D. (2013). Mapping Dirac gaugino masses. Journal of High Energy Physics, 2013(11), Article 098. https://doi.org/10.1007/jhep11%282013%29098

We investigate the mapping of Dirac gaugino masses through regions of strong coupling, focussing on SQCD with an adjoint. These models have a well-known Kutasov duality, under which a weakly coupled electric UV description can flow to a different wea... Read More about Mapping Dirac gaugino masses.

The Möbius–Wall congruences for p-adic L-functions of CM elliptic curves (2013)
Journal Article
Bouganis, A. (2014). The Möbius–Wall congruences for p-adic L-functions of CM elliptic curves. Mathematical Proceedings of the Cambridge Philosophical Society, 156(01), 183-192. https://doi.org/10.1017/s0305004113000625

In this paper we prove, under a technical assumption, the so-called “Möbius–Wall” congruences between abelian p-adic L-functions of CM elliptic curves. These congruences are the analogue of those shown by Ritter and Weiss for the Tate motive, and off... Read More about The Möbius–Wall congruences for p-adic L-functions of CM elliptic curves.

Cobordisms to weakly splittable links (2013)
Journal Article
Friedl, S., & Powell, M. (2014). Cobordisms to weakly splittable links. Proceedings of the American Mathematical Society, 142(2), 703-712. https://doi.org/10.1090/s0002-9939-2013-11792-2

We show that if a link L with non-zero Alexander polynomial admits a locally flat cobordism to a `weakly m-split link', then the cobordism must have genus at least (m-1)/2. This generalises a recent result of J. Pardon.

The dynamics of domain wall Skyrmions (2013)
Journal Article
Jennings, P., & Sutcliffe, P. (2013). The dynamics of domain wall Skyrmions. Journal of Physics A: Mathematical and Theoretical, 46(46), Article 465401. https://doi.org/10.1088/1751-8113/46/46/465401

It has recently been shown that Skyrmions with a fixed size can exist in theories without a Skyrme term, providing the Skyrmion is located on a domain wall. Here we numerically compute domain wall Skyrmions of this type, in a (2+1)-dimensional O(3) s... Read More about The dynamics of domain wall Skyrmions.

Platonic solids generate their four-dimensional analogues (2013)
Journal Article

This paper shows how regular convex 4-polytopes – the analogues of the Platonic solids in four dimensions – can be constructed from three-dimensional considerations concerning the Platonic solids alone. Via the Cartan–Dieudonne´ theorem, the reflecti... Read More about Platonic solids generate their four-dimensional analogues.

An important problem in wireless sensor networks is to nd an optimal number of randomly deployed sensors to guarantee connectivity of the resulting network with a given probability. The authors describe a general method to compute the probabilities o...

Interaction-driven charge localization across a quantum phase transition involves a fundamental rearrangement of the low-energy degrees of freedom. This fact challenges weakly interacting quasiparticle descriptions of the physics. The canonical examp... Read More about Interaction-driven localization in holography.

Comments on Hall transport from effective actions (2013)

We consider parity-odd transport in 2+1 dimensional charged fluids restricting attention to the class of non-dissipative fluids. We show that there is a two parameter family of such non-dissipative fluids which can be derived from an effective action... Read More about Comments on Hall transport from effective actions.

Global properties of causal wedges in asymptotically AdS spacetimes (2013)

We examine general features of causal wedges in asymptotically AdS space-times and show that in a wide variety of cases they have non-trivial topology. We also prove some general results regarding minimal area surfaces on the causal wedge boundary an... Read More about Global properties of causal wedges in asymptotically AdS spacetimes.

Essential hyperbolic Coxeter polytopes (2013)
Journal Article

We introduce a notion of an essential hyperbolic Coxeter polytope as a polytope which fits some minimality conditions. The problem of classification of hyperbolic reflection groups can be easily reduced to classification of essential Coxeter polytope... Read More about Essential hyperbolic Coxeter polytopes.

On the thermodynamics of periodic AdS black branes (2013)
Journal Article

We consider asymptotically AdS black brane solutions that are dual to CFTs with periodic dependence on the spatial directions, arising from either a spontaneous or an explicit breaking of translational symmetry. We derive a simple expression for the... Read More about On the thermodynamics of periodic AdS black branes.

Boundary conditions for metric fluctuations in Lifshitz (2013)

We consider the quantization of linearized fluctuations of the metric and matter fields about a Lifshitz background, exploring the possibility of alternative boundary conditions, allowing the slow fall-off modes to fluctuate. We find that for z > 2,... Read More about Boundary conditions for metric fluctuations in Lifshitz.

We study a random walk in random environment on ℤ+. The random environment is not homogeneous in law, but is a mixture of two kinds of site, one in asymptotically vanishing proportion. The two kinds of site are (i) points endowed with probabilities d... Read More about Random walk in mixed random environment without uniform ellipticity.

Double Handled Brane Tilings (2013)
Journal Article
Cremonesi, S., Hanany, A., & Seong, R. (2013). Double Handled Brane Tilings. Journal of High Energy Physics, 2013(10), Article 001. https://doi.org/10.1007/jhep10%282013%29001

We classify the first few brane tilings on a genus 2 Riemann surface and identify their toric Calabi-Yau moduli spaces. These brane tilings are extensions of tilings on the 2-torus, which represent one of the largest known classes of 4d N=1N=1 superc... Read More about Double Handled Brane Tilings.
