description: We use globular cluster kinematics data, primarily from the SLUGGS survey, to measure the dark matter fraction ($f_{\rm DM}$) and the average dark matter density ($\left< ρ_{\rm DM} \right>$) within the inner 5 effective radii ($R_{\rm e}$) for 32 nearby early--type galaxies (ETGs) with stellar mass log $(M_*/\rm M_\odot)$ ranging from $10.1$ to $11.8$. We compare our results with a simple galaxy model based on scaling relations as well as with cosmological hydrodynamical simulations where the dark matter profile has been modified through various physical processes. We find a high $f_{\rm DM}$ ($\geq0.6$) within 5~$R_{\rm e}$ in most of our sample, which we interpret as a signature of a late mass assembly history that is largely devoid of gas-rich major mergers. However, around log $(M_*/M_\odot) \sim 11$, there is a wide range of $f_{\rm DM}$ which may be challenging to explain with any single cosmological model. We find tentative evidence that lenticulars (S0s), unlike ellipticals, have mass distributions that are similar to spiral galaxies, with decreasing $f_{\rm DM}$ within 5~$R_{\rm e}$ as galaxy luminosity increases. However, we do not find any difference between the $\left< ρ_{\rm DM} \right>$ of S0s and ellipticals in our sample, despite the differences in their stellar populations. We have also used $\left< ρ_{\rm DM} \right>$ to infer the epoch of halo assembly ($z{\sim}2-4$). By comparing the age of their central stars with the inferred epoch of halo formation, we are able to gain more insight into their mass assembly histories. Our results suggest a fundamental difference in the dominant late-phase mass assembly channel between lenticulars and elliptical galaxies.

description: We present a new method for building sequences of solvable profiles of the electromagnetic (EM) admittance in lossless isotropic materials with 1D graded permittivity and permeability (in particular profiles of the optical refractive-index). These solvable profiles lead to analytical closed-form expressions of the EM fields, for both TE and TM modes. The Property-and-Field Darboux Transformations method, initially developed for heat diffusion modelling, is here transposed to the Maxwell equations in the optical-depth space. Several examples are provided, all stemming from a constant seed-potential, which makes them based on elementary functions only. Solvable profiles of increasingly complex shape can be obtained by iterating the process or by assembling highly flexible canonical profiles. Their implementation for modelling optical devices like matching layers, rugate filters, Bragg gratings, chirped mirrors or 1D photonic crystals, offers an exact and cost-effective alternative to the classical approaches

The model is non-Hermitian for $N \ge 3$ with a real ground state energy and a complex excitation spectrum. Although having a simpler Hamiltonian than the superintegrable chiral Potts model, the model is seen to share some properties with it, e.g., the specific heat exponent $α=1-2/N$ and the anisotropic correlation length exponents $ν_\parallel =1$ and $ν_\perp=2/N$.

description: Microwave Plasma Assisted (MPA) Chemical Vapour Deposition (CVD) optical quality polycrystalline diamond is used in shape of disks with thickness of 1 to 2 mm in window units for plasma heating and stabilization in nuclear fusion devices. Due to limited body of work in literature and the important safety role of the disks, fracture toughness measurements on this type of diamond are planned to check its resistance against crack propagation. In this work, the activities aiming to characterize the diamond samples prior to the experiments are discussed mainly with reference to X-ray diffraction, electron backscatter diffraction and loss tangent measurements. For in-depth understanding, thermal grade diamond has been also considered. It grows much faster than the optical grade and it has a greater density of microfeatures. In addition, the design and thermo-mechanical performance of a typical diamond window unit in nuclear fusion devices are presented.

description: A quantitative measure of quantum coherence was recently introduced, in the context of quantum information theory. This measure has also been propounded as a good quantifier of the wave nature of quantum objects. However, actually measuring coherence in an experiment is still considered a challenge. A procedure for measuring coherence in a multi-slit interference is proposed here. It can be used for experimentally testing duality relations for interference experiments involving more than two slits.

description: We investigate the effect of varying the ion temperature gradient (ITG) and toroidal equilibrium scale sheared flow on ion-scale turbulence in the outer core of MAST by means of local gyrokinetic simulations. We show that nonlinear simulations reproduce the experimental ion heat flux and that the experimentally measured values of the ITG and the flow shear lie close to the turbulence threshold. We demonstrate that the system is subcritical in the presence of flow shear, i.e., the system is formally stable to small perturbations, but transitions to a turbulent state given a large enough initial perturbation. We propose that the transition to subcritical turbulence occurs via an intermediate state dominated by low number of coherent long-lived structures, close to threshold, which increase in number as the system is taken away from the threshold into the more strongly turbulent regime, until they fill the domain and a more conventional turbulence emerges. We show that the properties of turbulence are effectively functions of the distance to threshold, as quantified by the ion heat flux. We make quantitative comparisons of correlation lengths, times, and amplitudes between our simulations and experimental measurements using the MAST BES diagnostic. We find reasonable agreement of the correlation properties, most notably of the correlation time, for which significant discrepancies were found in previous numerical studies of MAST turbulence.

Boundary regularity for conformally invariant variational problems with Neumann data

description: We study boundary regularity of maps from two-dimensional domains into manifolds which are critical with respect to a generic conformally invariant variational functional and which, at the boundary, enter perpendicularly into a support manifold. For example, harmonic maps, or $H$-surfaces, with a partially free boundary condition. In the interior it is known, by the celebrated work of Riviere, that these maps satisfy a system with an antisymmetric potential, from which one can derive regularity of the solution. We show that these maps satisfy along the boundary a system with a nonlocal antisymmetric boundary potential which contains information from the interior potential and the geometric Neumann boundary condition. We then proceed to show boundary regularity for solutions to such systems.

description: Thermal corrections in classically conformal models typically induce a strong first-order electroweak phase transition, thereby resulting in a stochastic gravitational wave background that could be detectable at gravitational wave observatories. After reviewing the basics of classically conformal scenarios, in this paper we investigate the phase transition dynamics in a thermal environment and the related gravitational wave phenomenology within the framework of scalar conformal extensions of the Standard Model. We find that minimal extensions involving only one additional scalar field struggle to reproduce the correct phase transition dynamics once thermal corrections are accounted for. Next-to-minimal models, instead, yield the desired electroweak symmetry breaking and typically result in a very strong gravitational wave signal.

description: Ab initio modeling of electrochemical systems is becoming a key tool for understanding and predicting electrochemical behavior. Development and careful benchmarking of computational electrochemical methods are essential to ensure their accuracy. Here, using charging curves for an electrode in the presence of an inert aqueous electrolyte, we demonstrate that most continuum models, which are parameterized and benchmarked for molecules, anions, and cations in solution, undersolvate metal surfaces, and underestimate the surface charge as a function of applied potential. We examine features of the electrolyte and interface that are captured by these models, and identify improvements necessary for realistic electrochemical calculations of metal surfaces. Finally, we reparameterize popular solvation models using the surface charge of Ag(100) as a function of voltage to find improved accuracy for metal surfaces without significant change in utility for molecular and ionic solvation.
title: Childfree Young Women’s Experiences of Employment Insecurity and Financial Autonomy in England
Creators: name: Hadfield, Sarah
Publisher: name: The Open University
Year: 2024

description: This thesis uses the concept of financial autonomy to investigate how childfree young women (CYW) aged 18–30, ‘get by’ when income is insecure. It suggests that the gendered conceptualisation of citizenship is not ‘universally’ applicable in practice, fractured as it is by age and parental status, and that youth transitions literature omits the experiences of this youth cohort.

 This study uses mixed methods, including secondary data analysis of the dataset Understanding Society to investigate the comparative labour market position of CYW. It reinterprets British social policy from the early 20th century to the present day, enabling an understanding of the institutional construction of ‘young womanhood’. Focus groups with a sample of the population of interest acted as a check and balance in the research process. An original self-administered survey gathered further information on the population of interest and was used to recruit 28 participants for in-depth semi-structured interviews. These were aided by calendar research methods.

 The findings indicate that CYW in insecure employment work in jobs that place them in the lowest socio-economic group. Their employment experiences demonstrate how CYW navigate oppression in the workplace in exchange for an independent income (wages). Although employment remains the main way for CYW to enact financial agency and privacy, it is not their only source of income. The financial resources accessed by CYW go beyond family, also including credit and partners. This thesis argues that theories of economic independence oversimplify the financial lives of CYW; culture and perceptions of the type of support that parents want to give their adult children influence what and how financial support is given. This thesis concludes that an attack on young people’s social rights is a forewarning to other age groups and highlights the need for an age and gendered-based approach to social policy analysis.

description: We study the conductance of a junction between the normal and superconducting segments of a nanowire, both of which are subjected to spin-orbit coupling and an external magnetic field. We directly compare the transport properties of the nanowire assuming two different models for the superconducting segment: one where we put superconductivity by hand into the wire, and one where superconductivity is induced through a tunneling junction with a bulk s-wave superconductor. While these two models are equivalent at low energies and at weak coupling between the nanowire and the superconductor, we show that there are several interesting qualitative differences away from these two limits. In particular, the tunneling model introduces an additional conductance peak at the energy corresponding to the bulk gap of the parent superconductor. By employing a combination of analytical methods at zero temperature and numerical methods at finite temperature, we show that the tunneling model of the proximity effect reproduces many more of the qualitative features that are seen experimentally in such a nanowire system.

description: We construct a Hennings type logarithmic invariant for restricted quantum $\mathfrak{sl}(2)$ at a $2\mathsf{p}$-th root of unity. This quantum group $U$ is not braided, but factorizable. The invariant is defined for a pair: a 3-manifold $M$ and a colored link $L$ inside $M$. The link $L$ is split into two parts colored by central elements and by trace classes, or elements in the $0^{\text{th}}$ Hochschild homology of $U$, respectively. The two main ingredients of our construction are the universal invariant of a string link with values in tensor powers of $U$, and the modified trace introduced by the third author with his collaborators and computed on tensor powers of the regular representation. Our invariant is a colored extension of the logarithmic invariant constructed by Jun Murakami.
The impact of China’s emissions trading scheme on corporate green innovation

Year: 2024
Subjects: classificationCode: 350201
subject: Environment and climate finance

description: This study investigates the impact of China’s emissions trading scheme (ETS) on the level of green innovation among Chinese listed companies. The results derived from the staggered difference-in-differences model indicate a substantial decrease in companies’ green innovation after the implementation of China’s ETS pilot policy. The baseline regression results remain unchanged after a battery of robustness checks.Cross-sectional analyses reveal that after the implementation of the ETS, companies with older executives are more inclined to reduce their level of green innovation. Moreover, private companies with higher financial constraints have experienced more significant decrease in their level of green innovation after the implementation of the ETS.This study further investigates the underlying mechanisms through which the ETS influences corporate green innovation. The findings show that the ETS has significantly reduced enterprises’ financial liquidity and profitability, thus leading to a decline in the level of green innovation of enterprises.More worryingly, additional analysis indicates that the decline in corporate green innovation brought about by the ETS has significantly increased corporate carbon emissions.This study contributes to the existing literature from two perspectives. First, most of the current literature explores the positive side of ETS on corporate green performance. This study, however, finds that implementing the ETS may also exert environmental pressure on companies, forcing companies to reduce green innovation to maintain normal operations. Second, this study provides practical guidance for regulatory authorities. The primary regulatory attention should be directed towards companies that managed by older executives with higher financial constraints and non-state ownership to enhance the effectiveness of the ETS implementation and so to achieve corporate sustainable development.

description: Alignment of electrostatic potential between different atomic configurations is necessary for first-principles calculations of band offsets across interfaces and formation energies of charged defects. However, strong oscillations of this potential at the atomic scale make alignment challenging, especially when atomic geometries change considerably from bulk to the vicinity of defects and interfaces. We introduce a method to suppress these strong oscillations by eliminating the deep wells in the potential at each atom. We demonstrate that this method considerably improves the system-size convergence of a wide range of first-principles predictions that depend on alignment of electrostatic potentials, including band offsets at solid-liquid interfaces, and formation energies of charged vacancies in solids and at solid surfaces in vacuum. Finally, we use this method in conjunction with continuum solvation theories to investigate energetics of charged vacancies at solid-liquid interfaces. We find that for the example of an NaCl (001) surface in water, solvation reduces the formation energy of charged vacancies by 0.5 eV: calculation of this important effect was previously impractical due to computational cost in molecular-dynamics methods.

Against the medicalisation of companion animals. A multispecies ethnography of care and companionship
Creators: name: Fletcher, Katherine Joy
Publisher: name: Macquarie University
Year: 2024
Subjects: classificationCode: 440199
subject: Anthropology not elsewhere classified

description: In modern Australian society, viewing negative human experiences as pathological events is becoming increasingly common. Experiences of suffering, trauma, stress, poverty, neurodivergence and anxiety are conceptualised in terms of clinical disorders, treatable through medical interventions. Human interactions with companion animals have also been medicalised through animal-assisted therapy, service animals, and individually proclaimed ‘emotional support animals’. In the process, interactions with non-humans have been commodified, researched, and medically sanctioned for their utility for human mental health. Yet, while these companions play a hugely significant role in human lives, their relationship to human health is more complicated and ambiguous than clinical psychological models allow. Medical literature often reduces the agency, individualism, and contextual behaviour of non-human species in favour of finding a statistically significant connection between the reduction of pathological symptoms and various human-animal interactions. Critiquing this project, this thesis explores the experience of living, healing, and suffering with non-human companions through a phenomenological lens. It looks beyond clinical psychological models to explore the intersubjective encounters, lively responses, and inevitable conflicts between different social species. Interactions with companion species can allow people to view themselves from different perspectives and undergo animal-motivated self-alteration. However, multispecies healing experiences are subjective. They involve an intersection of particular bonds between entities, the interests of the animals, and the attitudes and expectations of humans. Our shared mortality and sociality bind humans and our companion animals together but also create conflicts, existential suffering, and change.

The weaponisation of digital media for furthering the Jihadist ideology in Australia

subject: Technology, crime and surveillance

description: The benefits of digital media have been transformational and have led to the evolution of a digitally connected society. However, digital media has also been weaponised by extremist groups to further their agenda. The declaration of the establishment of a Caliphate by the Islamic State in 2014 and their sophisticated use of digital media have led to the reinvigoration of Jihadist activities, including in Australia. Since 2014, nine terrorist attacks have occurred, and sixteen proven plots have been foiled in Australia. Furthermore, as of early 2022, more than 100 persons have either been convicted of terrorism offences or are in prison charged with terrorism offences. Jihadism continues to be a significant threat to Australia, while digital media has not only expanded the threat landscape but has also gone through a significant transformation.Despite the significant role of digital media in Jihadist radicalisation (JR), recruitment, planning and mobilisation of people, the existing research has focused on a few media theories in isolation, while there are a very limited number of studies that provide a comprehensive outlook on the role of digital media in enabling JR. The research area of Jihadism with a focus on digital media is underexplored in Australia.This thesis examines key media theories in the context of Jihadist ideology and the role of digital media in the JR process, and proposes an emergent framework to explain digital JR. This ten-staged framework draws from an existing radicalisation model and has been elaborated further to meet the specific requirements in Australia. This framework will be instrumental in developing a deeper understanding of digital JR and in providing valuable insights to facilitate sharpening the current, Countering Violent Extremism initiatives, in addition to informing law enforcement and policy decisions on counter-terrorism strategies.

description: We present the Minimally-Implicit Runge-Kutta (MIRK) methods for the numerical evolution of the resistive relativistic magnetohydrodynamic (RRMHD) equations, following the approach proposed by Komissarov (2007) of an augmented system of evolution equations to numerically deal with constraints. Previous approaches rely on Implicit-Explicit (IMEX) Runge-Kutta schemes; in general, compared to explicit schemes, IMEX methods need to apply the recovery (which can be very expensive computationally) of the primitive variables from the conserved ones in numerous additional times. Moreover, the use of an iterative process for the recovery could have potential convergence problems, increased by the additional number of required loops. In addition, the computational cost of the previous IMEX approach in comparison with the standard explicit methods is much higher. The MIRK methods are able to deal with stiff terms producing stable numerical evolutions, minimize the number of recoveries needed in comparison with IMEX methods, their computational cost is similar to the standard explicit methods and can actually be easily implemented in numerical codes which previously used explicit schemes. Two standard numerical tests are shown in the manuscript.

description: The level of solar magnetic activity, as exemplified by the number of sunspots and by energetic events in the corona, varies on a wide range of time scales. Most prominent is the 11-year solar cycle, which is significantly modulated on longer time scales. Drawing from dynamo theory together with empirical results of past solar activity and of similar phenomena on solar-like stars, we show that the variability of the solar cycle can be essentially understood in terms of a weakly nonlinear limit cycle affected by random noise. In contrast to ad-hoc `toy models' for the solar cycle, this leads to a generic normal-form model, whose parameters are all constrained by observations. The model reproduces the characteristics of the variable solar activity on time scales between decades and millennia, including the occurrence and statistics of extended periods of very low activity (grand minima). Comparison with results obtained with a Babcock-Leighton-type dynamo model confirms the validity of the normal-mode approach.

On the migration-induced formation of the 9:7 mean motion resonance

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We study formation of 9:7 mean motion resonance (MMR) as a result of convergent migration of two planets embedded in a disc. Depending on the migration parameters, initial orbits and planets' masses the system may pass through the resonance or enter it (permanently or temporarily). We illustrate that a stable equilibrium of the averaged system (a periodic orbit of the N-body model) is surrounded by the region of permanent resonance capture, whose size depends on the migration parameters and the planets mass ratio. A system located inside this region tends towards the equilibrium (the capture is permanent), while a system located outside the region evolves away from the equilibrium and leaves the resonance. We verify recent results of Delisle et al. and Xu & Lai where they show that for $m_1 \lesssim m_2$ ($m_1, m_2$ are the inner and outer planets' masses) the equilibrium is unstable when the migration is added, so the capture cannot be permanent. We show that for particular migration parameters the situation may be reversed (the equilibria are unstable for $m_1 \gtrsim m_2$). We illustrate that 9:7 MMR consists of two modes separated with a separatrix. The inner one is centred at the equilibrium and the outer one has no equilibrium in its centre. A system located outside the region of stable capture evolves from the inner into the outer mode. The evolution occurs along families of periodic orbits of the averaged system, that play a crucial role in the dynamics after the resonance capture.

description: The computational cost of solving an inverse problem governed by PDEs, using multiple experiments, increases linearly with the number of experiments. A recently proposed method to decrease this cost uses only a small number of random linear combinations of all experiments for solving the inverse problem. This approach applies to inverse problems where the PDE solution depends linearly on the right-hand side function that models the experiment. As this method is stochastic in essence, the quality of the obtained reconstructions can vary, in particular when only a small number of combinations are used. We develop a Bayesian formulation for the definition and computation of encoding weights that lead to a parameter reconstruction with the least uncertainty. We call these weights A-optimal encoding weights. Our framework applies to inverse problems where the governing PDE is nonlinear with respect to the inversion parameter field. We formulate the problem in infinite dimensions and follow the optimize-then-discretize approach, devoting special attention to the discretization and the choice of numerical methods in order to achieve a computational cost that is independent of the parameter discretization. We elaborate our method for a Helmholtz inverse problem, and derive the adjoint-based expressions for the gradient of the objective function of the optimization problem for finding the A-optimal encoding weights. The proposed method is potentially attractive for real-time monitoring applications, where one can invest the effort to compute optimal weights offline, to later solve an inverse problem repeatedly, over time, at a fraction of the initial cost.

description: Internationally, the link between punitive school disciplinary practices and increased risk of contact with the justice system has been chronicled via a substantial body of research on the school-to-prison pipeline. This research highlights some of the harmful effects of exclusionary school discipline for some students, including lower educational achievement, lower school completion rates and future contact with the justice system. Drawing on some of the findings from 50 in-depth interviews with former prisoners, educators, parents, and a range of key stakeholders, this paper builds on that research by identifying the informal ways that some groups of students are subjected to exclusion in schools. The findings suggest that to fully understand the factors that impact the path from school to involvement with the justice system, greater attention should be paid to the experience of informal school-based exclusionary practices

description: We develop the formal tools needed to construct helicity amplitudes for massive gravitino in N=1 SUGRA. We start by considering the helicity states for massive spin-3/2 particles, which involves the solutions of Rarita-Schwinger equation. These solutions are written in terms of the helicity bra-ket notation and are used then to derive the interactions of gravitino with matter and gauge supermultiplets within N=1 Supergravity. The corresponding interactions of goldstinos are discussed too, relying on the goldstino-gravitino equivalence theorem. Finally to appreciate the power of our methods we evaluate the decay width chi_0 -> γG, as well as the cross sections for e^+ e- -> GG.
