Modal nudging in nonlinear elasticity: tailoring the elastic post-buckling behaviour of engineering structures (2018)
Journal Article

The buckling and post-buckling behaviour of slender structures is increasingly being harnessed for smart functionalities. Equally, the post-buckling regime of many traditional engineering structures is not being used for design and may therefore harb...

Wrinkling structures at the rim of an initially stratched circular thin plate subjected to transverse pressure (2018)
Journal Article

Short-wavelength wrinkles that appear on an initially stretched thin elastic plate under transverse loading are examined. As the degree of loading is increased so wrinkles appear and their structure at the onset of buckling takes on one of three dist...

Holomorphic automorphic forms and cohomology (2018)
Journal Article

© 2018 by the American Mathematical Society. All rights reserved. We investigate the correspondence between holomorphic automorphic forms on the upper half-plane with complex weight and parabolic cocycles. For integral weights at least 2 this corresp...

Sinusoidal voltage protocols for rapid characterisation of ion channel kinetics (2018)
Journal Article

Understanding the roles of ion currents is crucial to predict the action of pharmaceuticals and mutations in different scenarios, and thereby to guide clinical interventions in the heart, brain and other electrophysiological systems. Our ability to p... Read More about Sinusoidal voltage protocols for rapid characterisation of ion channel kinetics.

Clusters in nonsmooth oscillator networks (2018)
Journal Article

© 2018 American Physical Society. For coupled oscillator networks with Laplacian coupling, the master stability function (MSF) has proven a particularly powerful tool for assessing the stability of the synchronous state. Using tools from group theory... Read More about Clusters in nonsmooth oscillator networks.

The stack of Yang-Mills fields on Lorentzian manifolds (2018)
Journal Article

We provide an abstract definition and an explicit construction of the stack of non-Abelian Yang-Mills fields on globally hyperbolic Lorentzian manifolds. We also formulate a stacky version of the Yang-Mills Cauchy problem and show that its well-posed... Read More about The stack of Yang-Mills fields on Lorentzian manifolds.

Revisiting the cuscuton as a Lorentz-violating gravity theory (2018)
Journal Article

The cuscuton is a scalar field with infinite speed of propagation. It was introduced in the context of cosmology but it has also been claimed to resemble Horava gravity in a certain limit. Here we revisit the cuscuton theory as a Lorentz-violating gr... Read More about Revisiting the cuscuton as a Lorentz-violating gravity theory.

Diffuse-interface two-phase flow models with different densities: A new quasi-incompressible form and a linear energy-stable method (2018)
Journal Article

© 2018 World Scientific Publishing Company. While various phase-field models have recently appeared for two-phase fluids with different densities, only some are known to be thermodynamically consistent, and practical stable schemes for their numerica...

Morphological and genetic characterisation of the root system architecture of selected barley recombinant chromosome substitution lines using an integrated phenotyping approach (2018)
Journal Article

Discoveries on the genetics of resource acquisition efficiency are limited by the ability to measure plant roots in sufficient number and with adequate genotypic variability. This paper presents a root phenotyping study that explores ways to combine live...

Capturing the dynamics of a hybrid multiscale cancer model with a continuum model (2018)
Journal Article

Cancer is a complex disease involving processes at spatial scales from sub-cellular, like cell signalling, to tissue scale, such as vascular network formation. A number of multiscale models have been developed to study the dynamics that emerge from t... Read More about Capturing the dynamics of a hybrid multiscale cancer model with a continuum model.

Radiologic image-based statistical shape analysis of brain tumors (2018)
Journal Article

We propose a curve-based Riemannian-geometric approach for general shape-based statistical analyses of tumors obtained from radiologic images. A key component of the framework is a suitable metric that (1) enables comparisons of tumor shapes, (2) pro... Read More about Radiologic image-based statistical shape analysis of brain tumors.

Constructing neutron stars with a gravitational Higgs mechanism (2018)
Journal Article

In scalar-tensor theories, spontaneous scalarization is a phase transition that can occur in ultradense environments such as neutron stars. The scalar field develops a non-trivial configuration once the stars exceeds a compactness threshold. We recen... Read More about Constructing neutron stars with a gravitational Higgs mechanism.

Multiple linear regression modelling to predict the stability of polymer-drug solid dispersions: comparison of the effects of polymers and manufacturing methods on solid dispersion stability (2018)
Journal Article

Solid dispersions can be a successful way to enhance the bioavailability of poorly soluble drugs. Here 60 solid dispersion formulations were produced using ten chemically diverse, neutral, poorly soluble drugs, three commonly used polymers, and two m...

Three-dimensional plant architecture and sunlit-shaded patterns: a stochastic model of light dynamics in canopies (2018)
Working Paper

Background and Aims Diurnal changes in solar position and intensity combined with the structural complexity of plant architecture result in highly variable and dynamic light patterns within the plant canopy. This affects productivity through the comp... Read More about Three-dimensional plant architecture and sunlit-shaded patterns: a stochastic model of light dynamics in canopies.

Near-field strong coupling of single quantum dots (2018)
Journal Article

Strong coupling and resultant mixing of light and matter states is an important asset for future quantum technologies. Here we demonstrate deterministic room-temperature strong coupling of a mesoscopic colloidal quantum dot to a plasmonic nano resona...

Nonlinear dynamics of a dispersive anisotropic Kuramoto–Sivashinsky equation in two space dimensions (2018)
Journal Article

A Kuramoto–Sivashinsky equation in two space dimensions arising in thin film flows is considered on doubly periodic domains. In the absence of dispersive effects, this anisotropic equation admits chaotic solutions for sufficiently large length scales...

Mechanisms of dispersion in a porous medium (2018)
Journal Article

This paper studies the mechanisms of dispersion in the laminar flow through the pore space of a three-dimensional porous medium. We focus on preasymptotic transport prior to the asymptotic hydrodynamic dispersion regime, in which solute motion may be... Read More about Mechanisms of dispersion in a porous medium.

Journeys in big data statistics (2018)
Journal Article

The realm of big data is a very wide and varied one. We discuss old, new, small and big data, with some of the important challenges including dealing with highly-structured and object-oriented data. In many applications the objective is to discern pa... Read More about Journeys in big data statistics.

Limit-cycle oscillatory coexpression of cross-inhibitory transcription factors: a model mechanism for lineage promiscuity (2018)
Journal Article

Lineage switches are genetic regulatory motifs that govern and maintain the commitment of a developing cell to a particular cell fate. A canonical example of a lineage switch is the pair of transcription factors PU.1 and GATA-1, of which the former i...
