Helical Birods: An Elastic Model of Helically Wound Double-Stranded Rods (2014)
Journal Article
Prior, C. (2014). Helical Birods: An Elastic Model of Helically Wound Double-Stranded Rods. Journal of Elasticity, 117(2), 231-277. https://doi.org/10.1007/s10659-014-9472-7

We consider a geometrically accurate model for a helically wound rope constructed from two intertwined elastic rods. The line of contact has an arbitrary smooth shape which is obtained under the action of an arbitrary set of applied forces and moment...

Effective actions for anomalous hydrodynamics (2014)
Journal Article
Haehl, F. M., Loganayagam, R., & Rangamani, M. (2014). Effective actions for anomalous hydrodynamics. Journal of High Energy Physics, 2014(3), Article 034. https://doi.org/10.1007/jhep03%282014%29034

We argue that an effective field theory of local fluid elements captures the constraints on hydrodynamic transport stemming from the presence of quantum anomalies in the underlying microscopic theory. Focussing on global current anomalies for an arbi... Read More about Effective actions for anomalous hydrodynamics.

Badly approximable points on planar curves and a problem of Davenport (2014)
Journal Article
Badziahin, D., & Velani, S. (2014). Badly approximable points on planar curves and a problem of Davenport. Mathematische Annalen, 359(3-4), 969-1023. https://doi.org/10.1007/s00208-014-1020-z

Let C be two times continuously differentiable curve in R2 with at least one point at which the curvature is non-zero. For any i,j⩾0 with i+j=1, let Bad(i,j) denote the set of points (x,y)∈R2 for which max{∥qx∥1/i,∥qy∥1/j}>c/q for all q∈N. Here c=c(x...

Viruses and fullerenes - symmetry as a common thread? (2014)
Journal Article
Dechant, P., Wardman, J., Keef, T., & Twarock, R. (2014). Viruses and fullerenes - symmetry as a common thread?. Acta Crystallographica Section A: Foundations and Advances, 70(2), 162-167. https://doi.org/10.1107/s2053273313034220

The principle of affine symmetry is applied here to the nested fullerene cages (carbon onions) that arise in the context of carbon chemistry. Previous work on affine extensions of the icosahedral group has revealed a new organizational principle in v... Read More about Viruses and fullerenes - symmetry as a common thread?.

A Clifford algebraic framework for Coxeter group theoretic computations (2014)
Journal Article
Dechant, P. (2014). A Clifford algebraic framework for Coxeter group theoretic computations. Advances in Applied Clifford Algebras, 24(1), 89-108. https://doi.org/10.1007/s00006-013-0422-4

Real physical systems with reflective and rotational symmetries such as viruses, fullerenes and quasicrystals have recently been modeled successfully in terms of three-dimensional (affine) Coxeter groups. Motivated by this progress, we explore here t... Read More about A Clifford algebraic framework for Coxeter group theoretic computations.

Classification with decision trees from a nonparametric predictive inference perspective (2014)
Journal Article
Abellán, J., Baker, R., Coolen, F., Crossman, R., & Masegosa, A. (2014). Classification with decision trees from a nonparametric predictive inference perspective. Computational Statistics & Data Analysis, 71, 789-802. https://doi.org/10.1016/j.csda.2013.02.009

An application of nonparametric predictive inference for multinomial data (NPI) to classification tasks is presented. This model is applied to an established procedure for building classification trees using imprecise probabilities and uncertainty me...

Scattering amplitudes of massive N=2 gauge theories in three dimensions. (2014)
Journal Article
Agarwal, A., Lipstein, A. E., & Young, D. (2014). Scattering amplitudes of massive N=2 gauge theories in three dimensions. Physical Review D, 89(4), Article 045020. https://doi.org/10.1103/physrevd.89.045020

We study the scattering amplitudes of mass-deformed Chern-Simons theories and Yang-Mills-Chern-Simons theories with N=2 supersymmetry in three dimensions. In particular, we derive the on-shell supersymmetry algebras which underlie the scattering matr... Read More about Scattering amplitudes of massive N=2 gauge theories in three dimensions..

Bayes linear sufficiency in non-exchangeable multivariate multiple regressions (2014)
Journal Article
Wooff, D. (2014). Bayes linear sufficiency in non-exchangeable multivariate multiple regressions. Bayesian Analysis, 9(1), 77-96. https://doi.org/10.1214/13-ba847

We consider sufficiency for Bayes linear revision for multivariate multiple regression problems, and in particular where we have a sequence of multivariate observations at different matrix design points, but with common parameter vector. Such sequenc... Read More about Bayes linear sufficiency in non-exchangeable multivariate multiple regressions.

Theoretical analysis for the optical deformation of emulsion droplets (2014)
Journal Article
Tapp, D., Taylor, J., Lubansky, A., Bain, C., & Chakrabarti, B. (2014). Theoretical analysis for the optical deformation of emulsion droplets. Optics Express, 22(4), 4523-4538. https://doi.org/10.1364/oe.22.004523

We propose a theoretical framework to predict the three-dimensional shapes of optically deformed micron-sized emulsion droplets with ultra-low interfacial tension. The resulting shape and size of the droplet arises out of a balance between the interf... Read More about Theoretical analysis for the optical deformation of emulsion droplets.
