A little excitement across the horizon (2022)
Journal Article

We analyse numerically the transitions in an Unruh-DeWitt detector, coupled linearly to a massless scalar field, in radial infall in (3 + 1)-dimensional Schwarzschild spacetime. In the Hartle-Hawking and Unruh states, the transition probability attai... Read More about A little excitement across the horizon.

Fostering purposeful engagement by building staff-student communities (2022)
Journal Article

In response to the Covid-19 pandemic, many universities moved to a blended delivery of online and in-person teaching. While necessary for public health, this significant disruption to education risked greater isolation and anxiety for students with...

Non-local effects on travelling waves arising in a moving-boundary reaction-diffusion model (2022)
Journal Article

We examine travelling wave solutions of the partial differential equation u_t = u_xx + u(1 − u * φ) on a moving domain x ≤ L(t), where u * φ is the spatial convolution of the population density with a kernel φ(y). We provide asymptotic approximations... Read More about Non-local effects on travelling waves arising in a moving-boundary reaction-diffusion model.

Exact smooth and sharp-fronted travelling waves of reaction–diffusion equations with Weak Allee effects (2022)
Journal Article

We provide new exact forms of smooth and sharp-fronted travelling wave solutions of the reaction–diffusion equation, ∂tu=R(u)+∂xD(u)∂xu, where the reaction term, R(u), employs a Weak Allee effect. The resulting ordinary differential equation system i... Read More about Exact smooth and sharp-fronted travelling waves of reaction–diffusion equations with Weak Allee effects.

Antimicrobial resistance in dairy slurry tanks: a critical point for measurement and control (2022)
Journal Article

Waste from dairy production is one of the largest sources of contamination from antimicrobial resistant bacteria (ARB) and genes (ARGs) in many parts of the world. However, studies to date do not provide necessary evidence to inform antimicrobial res...

Tunable Graphene-based Metasurfaces for Multi-Wideband 6G Communications (2022)
Conference Proceeding

The next generation of wireless communications within the framework of 6G will be operational at the low THz frequency band. Although THz systems will dramatically enhance several performance indicators such as the data rate, spectral efficiency, and...

Acoustic radiation from random waves on plates (2022)
Journal Article

Controlling and simulating the sound radiating from complex structures is of importance in many engineering applications. We calculate the radiated acoustic power from plates with diffuse bending vibrations. We characterise the diffuse field by a two... Read More about Acoustic radiation from random waves on plates.

A functional central limit theorem for SI processes on configuration model graphs (2022)
Journal Article

We study a stochastic compartmental susceptible–infected (SI) epidemic process on a configuration model random graph with a given degree distribution over a finite time interval. We split the population of graph vertices into two compartments, namely... Read More about A functional central limit theorem for SI processes on configuration model graphs.

Modeling root loss reveals impacts on nutrient uptake and crop development (2022)
Journal Article

Abstract Despite the widespread prevalence of root loss in plants, its effects on crop productivity are not fully understood. While root loss reduces the capacity of plants to take up water and nutrients from the soil, it may provide benefits by decr...

Models of the cardiac L-type calcium current: A quantitative review (2022)
Journal Article

The L-type calcium current ((Formula presented.)) plays a critical role in cardiac electrophysiology, and models of (Formula presented.) are vital tools to predict arrhythmogenicity of drugs and mutations. Five decades of measuring and modeling (Form... Read More about Models of the cardiac L-type calcium current: A quantitative review.

Controlling resin flow in Liquid Composite Moulding processes through localized irradiation with ultraviolet light (2022)
Journal Article

A vacuum infusion process was implemented to produce composite specimens from a random glass filament mat and an acrylic modified polyester resin curable upon irradiation with ultraviolet (UV) light. Through localized irradiation with UV light during... Read More about Controlling resin flow in Liquid Composite Moulding processes through localized irradiation with ultraviolet light.

A Skeletal Model for 2d Conformal AQFTs (2022)
Journal Article

A simple model for the localization of the category CLoc2 of oriented and time-oriented globally hyperbolic conformal Lorentzian 2-manifolds at all Cauchy morphisms is constructed. This provides an equivalent description of 2-dimensional conformal al... Read More about A Skeletal Model for 2d Conformal AQFTs.

Long-term seizure, psychiatric and socioeconomic outcomes after frontal lobe epilepsy surgery (2022)
Journal Article

Objective: Resective surgery for selected individuals with frontal lobe epilepsy can be effective, although multimodal outcomes are less established than in temporal lobe epilepsy. We describe long-term seizure remission and relapse patterns, psychia... Read More about Long-term seizure, psychiatric and socioeconomic outcomes after frontal lobe epilepsy surgery.

Extreme mass-ratio inspirals as probes of scalar fields: Eccentric equatorial orbits around Kerr black holes (2022)
Journal Article

We study binary systems in which a stellar mass compact object spirals into a massive black hole, known as extreme mass ratio inspirals, in scenarios with a new fundamental scalar field. Earlier work has shown that, in most interesting such scenarios... Read More about Extreme mass-ratio inspirals as probes of scalar fields: Eccentric equatorial orbits around Kerr black holes.
