Zeros of derivatives of strictly nonreal meromorphic functions (2020)
Journal Article

Let f be a meromorphic function in the plane and let e f(z) = f(_z) (this notation will be used throughout). Here f is called real if e f = f, and strictly non-real if e f is not a constant multiple of f. There has been substantial research concernin...

An asymptotic analysis of the malonyl-CoA route to 3-hydroxypropionic acid in genetically engineered microbes (2020)
Journal Article

There has been recent interest in creating an efficient microbial production route for 3-hydroxypropionic acid, an important platform chemical. We develop and solve a mathematical model for the time-dependent metabolite concentrations in the malonyl-...

New travelling wave solutions of the Porous–Fisher model with a moving boundary (2020)
Journal Article

We examine travelling wave solutions of the Porous-Fisher model, ϑtu(x,t) = u(x,t)[1 u(x,t)] + ϑx [u(x,t)ϑxu(x,t)], with a Stefan-like condition at the moving front, x = L(t). Travelling wave solutions of this model have several novel characteristics... Read More about New travelling wave solutions of the Porous–Fisher model with a moving boundary.

Study Habits and Attainment in Undergraduate Mathematics: A Social Network Analysis (2020)
Journal Article

In this paper, we argue that although mathematics educators are concerned about social issues, minimal attention has been paid to student-student interactions outside the classroom. We discuss social network analysis (SNA) as a methodology for studyi... Read More about Study Habits and Attainment in Undergraduate Mathematics: A Social Network Analysis.

Latest developments on the shielding effectiveness measurements of materials and gaskets in reverberation chambers (2019)
Journal Article

In this study, the authors present the latest developments on the measurements for the shielding effectiveness (SE) of gaskets and materials in reverberation chambers (RCs). A variant method, where the insertion loss of the fixture is achieved from t...

Demonstrating Quantum Coherence and Metrology that is Resilient to Transversal Noise (2019)
Journal Article

© 2019 American Physical Society. Quantum systems can be exploited for disruptive technologies but in practice quantum features are fragile due to noisy environments. Quantum coherence, a fundamental such feature, is a basis-dependent property that i... Read More about Demonstrating Quantum Coherence and Metrology that is Resilient to Transversal Noise.

A multiphase multiscale model for nutrient limited tissue growth, Part II: A simplified description (2019)
Journal Article

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

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... Read More about Pushing the limits of the reaction-coordinate mapping.

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...

New Semiclassical Picture of Vacuum Decay (2019)
Journal Article

© 2019 authors. Published by the American Physical Society. We introduce a new picture of vacuum decay which, in contrast to existing semiclassical techniques, provides a real-time description and does not rely on classically forbidden tunneling path...

Black holes, gravitational waves and fundamental physics: A roadmap (2019)
Journal Article

© 2019 IOP Publishing Ltd. The grand challenges of contemporary fundamental physics-dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-all involve gravity as a key component. And o... Read More about Black holes, gravitational waves and fundamental physics: A roadmap.

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... Read More about Spontaneous scalarization in generalized scalar-tensor theory.

Classification of shift-symmetric Horndeski theories and hairy black holes (2019)
Journal Article

No-hair theorems for scalar-tensor theories imply that the trivial scalar field configuration is the unique configuration around stationary black hole spacetimes. The most basic assumption in these theorems is that a constant scalar configuration is... Read More about Classification of shift-symmetric Horndeski theories and hairy black holes.

A dam-break driven by a moving source: a simple model for a powder snow avalanche (2019)
Journal Article

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... Read More about A dam-break driven by a moving source: a simple model for a powder snow avalanche.

Multipole moments and universal relations for scalarized neutron stars (2019)
Journal Article

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... Read More about Multipole moments and universal relations for scalarized neutron stars.

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... Read More about Operational advantage of quantum resources in subchannel discrimination.
