In this paper, we revisit and extend our recent work (Holden et al. (2018) A multiphase multiscale model for nutrient limited tissue growth, The ANZIAM Journal, 59(4), 499-532), that considers the derivation of an effective macroscale description sui...

Pushing the limits of the reaction-coordinate mapping (2019)
Journal Article
Correa, L. A., Xu, B., Morris, B., & Adesso, G. (2019). Pushing the limits of the reaction-coordinate mapping. Journal of Chemical Physics, 151(9), https://doi.org/10.1063/1.5114690

The reaction-coordinate mapping is a useful technique to study complex quantum dissipative dynamics into structured environments. In essence, it aims to mimic the original problem by means of an “augmented system,” which includes a suitably chosen co...

Too little, too late? Brexit Day, transitional periods and the implications of MIB v Lewis (2019)
Journal Article
Mason, J., & Ferris, K. (in press). Too little, too late? Brexit Day, transitional periods and the implications of MIB v Lewis. European Law Review,

For several decades the UK has been in breach of key aspects of the Motor Vehicle Insurance Directives (MVID). This has been observed through academic commentary and confirmed in successful state liability claims. There has also been a manifestly inc...

Local and global energies for shape analysis in medical imaging (2019)
Journal Article

In a previous contribution a new Riemannian shape space, named TPS space, was introduced to perform statistics on shape data. This space was endowed with a Rie-mannian metric and a flat connection, with torsion, compatible with the given metric. This...

Extendibility of bosonic Gaussian states (2019)
Journal Article

Extendibility of bosonic Gaussian states is a key issue in continuous-variable quantum information. We show that a bosonic Gaussian state is k-extendible if and only if it has a Gaussian k-extension, and we derive a simple semidefinite program, whose...

Slow travelling wave solutions of the nonlocal Fisher-KPP equation (2019)
Journal Article
BILLINGHAM, J. Slow travelling wave solutions of the nonlocal Fisher-KPP equation. Manuscript submitted for publication

We study travelling wave solutions, $u \equiv U(x-ct)$, of the nonlocal Fisher-KPP equation in one spatial dimension, $u_t = D u_{xx} + u\left(1 - \phi * u\right),$ with $D \ll 1$ and $c \ll 1$, where $\phi * u$ is the spatial convolution of...

Spontaneous scalarization in generalized scalar-tensor theory (2019)
Journal Article

Spontaneous scalarization is a mechanism that endows relativistic stars and black holes with a nontrivial configuration only when their spacetime curvature exceeds some threshold. The standard way to trigger spontaneous scalarization is via a tachyon...

Multipole moments and universal relations for scalarized neutron stars (2019)
Journal Article
Pappas, G., Doneva, D. D., Sotiriou, T. P., Yazadjiev, S. S., & Kokkotas, K. D. (2019). Multipole moments and universal relations for scalarized neutron stars. Physical Review D, 99(10), doi:10.1103/physrevd.99.104014

In recent years there has been a surge of interest in what has come to be known as the “universal relations” between various global properties of neutron stars. These universal relations are equation of state independent relations between quantities...

A dam-break driven by a moving source: a simple model for a powder snow avalanche (2019)
Journal Article
Billingham, J. (2019). A dam-break driven by a moving source: a simple model for a powder snow avalanche. Journal of Fluid Mechanics, 870, 353-388. doi:10.1017/jfm.2019.273

We study the two-dimensional, irrotational flow of an inviscid, incompressible fluid injected from a line source moving at constant speed along a horizontal boundary, into a second, immiscible, inviscid fluid of lower density. A semi-infinite, horizo...

Operational advantage of quantum resources in subchannel discrimination (2019)
Journal Article

One of the central problems in the study of quantum resource theories is to provide a given resource with an operational meaning, characterizing physical tasks in which the resource can give an explicit advantage over all resourceless states. We show...

A core mechanism for specifying root vascular pattern can replicate the anatomical variation seen in diverse plant species (2019)
Journal Article
Mellor, N., Vaughan-Hirsch, J., Kümpers, B. M., Help-Rinta-Rahko, H., Miyashima, S., Pekka Mähönen, A., …Bishopp, A. (2019). A core mechanism for specifying root vascular pattern can replicate the anatomical variation seen in diverse plant species. Development, 146, doi:10.1242/dev.172411

Pattern formation is typically controlled through the interaction between molecular signals within a given tissue. During early embryonic development, roots of the model plant Arabidopsis thaliana have a radially symmetric pattern, but a heterogeneou...

Rost nilpotence and free theories (2018)
Journal Article
Gille, S., & Vishik, A. (2018). Rost nilpotence and free theories. Documenta Mathematica, 23, 1635-1657

We introduce coherent cohomology theories h_* and prove that if such a theory is moreover generically constant then the Rost nilpotence principle holds for projective homogeneous varieties in the category of h_*-motives. Examples of such theories are...
