description: The action of any local operator on a quantum system propagates through the system carrying the information of the operator. This is usually studied via the out-of-time-order correlator (OTOC). We numerically study the information propagation from one end of a periodically driven spin-1/2 $XY$ chain with open boundary conditions using the Floquet infinite-temperature OTOC. We calculate the OTOC for two different spin operators, $σ^x$ and $σ^z$. For sinusoidal driving, the model can be shown to host different types of edge states, namely, topological (Majorana) edge states and non-topological edge states. We observe a localization of information at the edge for both $σ^z$ and $σ^x$ OTOCs whenever edge states are present. In addition, in the case of non-topological edge states, we see oscillations of the OTOC in time near the edge, the oscillation period being inversely proportional to the gap between the Floquet eigenvalues of the edge states. We provide an analytical understanding of these effects due to the edge states. It was known earlier that the OTOC for the spin operator which is local in terms of Jordan-Wigner fermions ($σ^z$) shows no signature of information scrambling inside the light cone of propagation, while the OTOC for the spin operator which is non-local in terms of Jordan-Wigner fermions ($σ^x$) shows signatures of scrambling. We report a remarkable `unscrambling effect' in the $σ^x$ OTOC after reflections from the ends of the system. Finally, we demonstrate that the information propagates into the system mainly via the bulk states with the maximum value of the group velocity, and we show how this velocity is controlled by the driving frequency and amplitude.

description: Opioid drugs are highly effective for the treatment of moderate to severe nociceptive pain. They exert their analgesic and rewarding effects primarily by signalling through the μ-opioid receptor (MOPr). The focus of this project was to better understand MOPr signalling regulation by investigating natural variants of MOPr and MOPr phosphosite mutants. Isogenic, stably transfected mouse pituitary adenoma (AtT20) cell lines expressing eight naturally occurring human MOPr variants and four phosphomutants were created. Opioid-stimulated changes in membrane potential were measured using a membrane potential-sensitive dye, while receptor phosphorylation of Ser 377 residue was determined by Western Blot and whole-cell ELISA was used to obtain the receptor surface loss dynamics. The N-terminal MOPr variants, A6V and N40D, are the most common single-nucleotide polymorphisms found worldwide. Their signalling regulation was quite similar to the wild-type MOPr in each assay, where buprenorphine was the opiod with the most variance observed. In AtT20-hMOPr-L85I cells morphine mediated internalisation was not as substantial as previously reported, while the second intracellular loop (ICL2) polymorphism R181C dramatically impacted receptor ability to signal by affecting opioid affinity and probably G protein binding. The majority of the third intracellular loop (ICL3) variants had detrimental effect in receptor signalling and regulation which indicates the important role this region plays in G protein activation. In addition the multiple phosphorylation mutants also affected membrane expression which was related to endoplasmic reticulum sequestration and possible changes in receptor stability. Finally, deleting all the putative phosphorylation sites in the human MOPr C-terminal domain did not greatly influence homologous desensitisation of the membrane potential signal, yet completely abolished internalisation as expected. In contrast heterologous desensitisation was deeply compromised in some mutants of the ICL3 while total phosphorylation deletion of the C-terminal was the only variant to increase desensitisation of somatostatin signalling. Interestingly buprenorphine induced signalling had a quite different profile across the variants, and morphine and methodone signalling were more affected by the ICL3 changes when compared to opioid peptides and buprenorphine. Overall, these results support the hypothesis of multiple mechanisms involved in regulation of MOPr, where ICL2 and ICL3 are crucial for G protein signalling, and receptor phosphorylation is not necessary for receptor desensitisation. In addition, this work highlights the profound effect of rare polymorphisms on opioid response at the molecular level, which is likey to contribute to the significant inter-individual variability observed with opioid therapy.

description: Random plane wave is conjectured to be a universal model for high-energy eigenfunctions of the Laplace operator on generic compact Riemanian manifolds. This is known to be true on average. In the present paper we discuss one of important geometric observable: critical points. We first compute one-point function for the critical point process, in particular we compute the expected number of critical points inside any open set. After that we compute the short-range asymptotic behaviour of the two-point function. This gives an unexpected result that the second factorial moment of the number of critical points in a small disc scales as the fourth power of the radius.

Motion-induced enhancement of Rabi coupling between atomic ensembles in cavity optomechanics

description: We propose a scheme of enhancement of Rabi coupling between two identical atomic ensembles trapped inside an optical cavity in a membrane-in-the-middle set up. The cavity modes dispersively interact with the ensembles and the effective interaction between the ensembles is governed by the tunnelling rate of the cavity modes through the oscillating membrane. We have shown that this interaction can be made large enough such that the Rabi oscillation occurs in a time-scale, much smaller than the relevant decay time-scales of the cavity modes and of the membrane. We present the detailed analytical and numerical results and assess the feasibility of the scheme using currently available technology.

description: In this thesis, I examine current trends in parenting on the Central Coast, New South Wales (NSW). I explore the concerns, perceptions and everyday experiences of parents with children under five. Specifically, I aim to analyse the anxieties and concerns of parents during child-rearing and how this affects their everyday life. Parenting has become "expert guided, child-centred, emotionally absorbing and financially expensive" (Hays 1996). I will examine the underlying social expectations that allow for a more intensive form of parenting to exist. The impact of different forms of advice and gendered notions of mothering are explored to highlight how they affect parents’ feelings of guilt, judgement and self-doubt. My research also explores the role that the media plays in making parents feel anxious, guilty or judged, based on their child-rearing choices. My research is based upon in-depth interviews with 12 parents and four professionals within child-related industries and participant observation at a local playgroup over six months. Overall, I concluded that there are several key interrelated societal factors including mothers’ dual role as primary caregiver and employee, the conflict between mother’s sense of identity and childrearing responsibility and judgement from parents themselves and external sources, including friends, family and through social media.

description: We chart out the phase diagram of ultracold `spin-half' bosons in a one-dimensional optical lattice in the presence of Aubry-André (AA) potential and with spin-orbit (SO) and Raman couplings investigating the transition from superfluid (SF) to localized phases and the existence of density wave phase for nearest-neighbor interaction (NNI). We show that the presence of SO coupling and AA potential leads to a novel spin-split momentum distribution of the bosons in the localized phase near the boundary with the SF phase, which can act as a signature of such a transition. We also obtain the level statistics of the bosons in the superfluid phase with finite NNI and demonstrate its change from Gaussian Unitary Ensemble (GUE) to Gaussian Orthogonal Ensemble (GOE) as a function of the Raman coupling. We discuss experiments which can test our theory.

description: We present a radio-quiet quasar at z=0.237 discovered "turning on" by the intermediate Palomar Transient Factory (iPTF). The transient, iPTF 16bco, was detected by iPTF in the nucleus of a galaxy with an archival SDSS spectrum with weak narrow-line emission characteristic of a low-ionization emission line region (LINER). Our follow-up spectra show the dramatic appearance of broad Balmer lines and a power-law continuum characteristic of a luminous (L_bol~10^45 erg/s) type 1 quasar 12 years later. Our photometric monitoring with PTF from 2009-2012, and serendipitous X-ray observations from the XMM-Newton Slew Survey in 2011 and 2015, constrain the change of state to have occurred less than 500 days before the iPTF detection. An enhanced broad Halpha to [OIII]5007 line ratio in the type 1 state relative to other changing-look quasars also is suggestive of the most rapid change of state yet observed in a quasar. We argue that the >10 increase in Eddington ratio inferred from the brightening in UV and X-ray continuum flux is more likely due to an intrinsic change in the accretion rate of a pre-existing accretion disk, than an external mechanism such as variable obscuration, microlensing, or the tidal disruption of a star. However, further monitoring will be helpful in better constraining the mechanism driving this change of state. The rapid "turn on" of the quasar is much shorter than the viscous infall timescale of an accretion disk, and requires a disk instability that can develop around a ~10^8 M_sun black hole on timescales less than a year.

Offline Supervised Learning V.S. Online Direct Policy Optimization: A Comparative Study and A Unified Training Paradigm for Neural Network-Based Optimal Feedback Control

description: This work is concerned with solving neural network-based feedback controllers efficiently for optimal control problems. We first conduct a comparative study of two prevalent approaches: offline supervised learning and online direct policy optimization. Albeit the training part of the supervised learning approach is relatively easy, the success of the method heavily depends on the optimal control dataset generated by open-loop optimal control solvers. In contrast, direct policy optimization turns the optimal control problem into an optimization problem directly without any requirement of pre-computing, but the dynamics-related objective can be hard to optimize when the problem is complicated. Our results underscore the superiority of offline supervised learning in terms of both optimality and training time. To overcome the main challenges, dataset and optimization, in the two approaches respectively, we complement them and propose the Pre-train and Fine-tune strategy as a unified training paradigm for optimal feedback control, which further improves the performance and robustness significantly.

"It's like DNA you know?": analysing genealogies of listening in Australian hip hop
Creators: name: Cox, James
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: From 2011-2016, Australian hip hop has diversified, welcoming local and international attention, in a period some believe is the ‘Golden Age’ (Ziegler 2016) of the genre. Using an ethnographic approach, this thesis provides an exploration of the events and artists involved within this ‘Golden Age’ and analyses the key issues in Australian hip hop, including; identity, race, gender, community, global traits of the genre and local influences. Ten Australian MCs and four key community events provide reference points which demonstrate distinct genealogies of listening that inform analysis, giving a unique snapshot of the genre within an Australian geography. The thesis highlights that the Australian hip hop scene is in a transitional period, as it becomes more mainstream and inclusive of both artists and fans. The result is a distinct local scene that, while building on a core cultural centre shared by hip hop communities worldwide, provides a more inclusive environment of cultural production. Such inclusion is demonstrated through the lack of tension and separation between those who consider hip hop to be a broader culture, and those who engage with hip hop specifically as a genre of music. The thesis documents that even those Australian MCs who do not strongly identify with hip hop culture are embraced by those that do. Inclusion is also demonstrated by accepting approaches to race and gender purported by key artists within the scene. In analysing the shared listening histories of Australian hip hop artists, the thesis exemplifies the importance of genealogies of listening within the genre, demonstrating how hip hop is used by artists in the formation of their identities, whilst also producing unifying traits that define Australian hip hop as it matures and continues to develop as a distinct local hip hop scene.

description: Non divergence-free discretisations for the incompressible Stokes problem may suffer from a lack of pressure-robustness characterised by large discretisations errors due to irrotational forces in the momentum balance. This paper argues that also divergence-free virtual element methods (VEM) on polygonal meshes are not really pressure-robust as long as the right-hand side is not discretised in a careful manner. To be able to evaluate the right-hand side for the testfunctions, some explicit interpolation of the virtual testfunctions is needed that can be evaluated pointwise everywhere. The standard discretisation via an L2 -bestapproximation does not preserve the divergence and so destroys the orthogonality between divergence-free testfunctions and possibly eminent gradient forces in the right-hand side. To repair this orthogonality and restore pressure-robustness another divergence-preserving reconstruction is suggested based on Raviart--Thomas approximations on local subtriangulations of the polygons. All findings are proven theoretically and are demonstrated numerically in two dimensions. The construction is also interesting for hybrid high-order methods on polygonal or polyhedral meshes.

Additionally we introduce a flexible graphical user interface (GUI) to accommodate these and future families of equations. This paper describes the new GUI architecture and summarizes the formal representation and implementation of these new families, providing several validation results.

Structural determination, identification and removal of Bayer liquor organic poisons
Creators: name: Maher, Regina Elizabeth
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Large financial investments are required for the precipitation step of the Bayer Process to ensure moderate yields of gibbsite are recovered. This step is crucial for Al(OH)₃ production but unfortunately is subjected to inhibition caused by the presence of particular organic matter known as 'poisons'. Despite extensive research performed to mitigate these inhibiting effects, they have experienced severe limitation. The structure of the poisons is essential for understanding how inhibition is induced and consequently, how they can be removed. A new extraction and derivatisation method was developed using SPME with a polyacrylate fibre, coupled with MTBSTFA on-fibre derivatisation for analysing Bayerl Liquor OM. As a result, 65 organic compounds were structurally characterised. Importantly, this OM identification process confirmed the absence of model poisons, namely polyhydroxyls, within Bayer Liquor. A comparative study of Bayer Liquor organics, both pre and post gibbsite harvesting was used to identify the poisons. From this, 7 poisons were proposed with the inhibiting functionality identified. To this end, a novel OM removal strategy was investigated which focused on transforming these highly polar poisons into volatiles. This removal strategy presents potential for mitigating inhibiting effect as some OM were successfully removed from the liquor in the form of pyrroles.
Superstition, sin and subversion: maritime culture in Constantinople and port cities of the East in Late Antiquity and Early Byzantium
Creators: name: Wade, Janet
Publisher: name: Macquarie University

description: The importance of sea-going trade to the Late Antique economy is widely recognised in scholarship, yet the people associated with this trade and its social impact are often overlooked. The sea played a significant social and cultural role in the lives, traditions and psyche of those living in and around the Mediterranean and Black Sea regions. In large port cities like Constantinople and Alexandria, the maritime community must have had a substantial effect on everyday life, culture and social dynamics. This thesis examines the people and professions which comprised maritime society. It looks at leisure establishments such as taverns, theatres, baths and brothels, and at those who worked in them, servicing mariners when they were onshore. Civil and maritime legislation, literary sources and archaeological evidence are investigated to conduct a sociological study of maritime society, its associated culture, and its influence on general society in the fourth to seventh centuries. The idea that members of the maritime community were collectively viewed as outsiders on the periphery of society is explored. So too is the role of sailors and sea-merchants in lower-class leisure culture in urban centres. Distinguishing features of maritime sub-culture are considered, including seafaring superstitions, traditions and practices. The role of maritime society in episodes of unrest is also investigated. Mariners provided strong-arm support for religious and political leaders, displayed a natural propensity for trouble, and were the perfect recruits for a range of uprisings. Importantly, the maritime community also facilitated communication networks that enabled institutions like the Church and circus factions to function as successful empire-wide organisations. Maritime sub-culture may have been an undesirable element of society, yet it was a significant one. It helped to shape the nature of Late Antique and Early Byzantine society and culture; even in Constantinople, the Queen of Cities.

description: Learning from the crowd has become increasingly popular in the Web and social media. There is a wide variety of crowdlearning sites in which, on the one hand, users learn from the knowledge that other users contribute to the site, and, on the other hand, knowledge is reviewed and curated by the same users using assessment measures such as upvotes or likes. In this paper, we present a probabilistic modeling framework of crowdlearning, which uncovers the evolution of a user's expertise over time by leveraging other users' assessments of her contributions. The model allows for both off-site and on-site learning and captures forgetting of knowledge. We then develop a scalable estimation method to fit the model parameters from millions of recorded learning and contributing events. We show the effectiveness of our model by tracing activity of ~25 thousand users in Stack Overflow over a 4.5 year period. We find that answers with high knowledge value are rare. Newbies and experts tend to acquire less knowledge than users in the middle range. Prolific learners tend to be also proficient contributors that post answers with high knowledge value.

description: Social Impact Assessment (SIA) practitioners in major urban transport infrastructure projects, assess and facilitate the equitable distribution of social benefits and costs, while balancing governmental policy objectives and stakeholder interests. Public investment in transport infrastructure shapes the future of cities, yet post-facto evaluation of SIA for such projects is rare. This thesis develops an evaluation framework for post-facto assessment of transport infrastructure project SIAs, which will improve societal understanding of the relationship between project, outcomes and policy objectives. Using the Parramatta Rail Link proposal as a case study, it examines external political decision-making forces, namely government, regulatory and financial processes, that influence whether social and transport policy objectives can be met, against the influence of strategic government masterplans and the development approval process. SIA and Environmental Impact Assessment (EIA) practitioners assist projects in meeting policy objectives by applying good practice during the EIA process. Long-term accountability is established external to political cycles, through legally-enforced effective management strategies and monitoring programs. This research highlights that the agenda of strategic social and transport policy objectives should be considered as early as during the business case development, to achieve the greatest potential for delivering equitable social outcomes.

Directed negative-weight percolation

description: We consider a directed variant of the negative-weight percolation model in a two-dimensional, periodic, square lattice. The problem exhibits edge weights which are taken from a distribution that allows for both positive and negative values. Additionally, in this model variant all edges are directed. For a given realization of the disorder, a minimally weighted loop/path configuration is determined by performing a non-trivial transformation of the original lattice into a minimum weight perfect matching problem. For this problem, fast polynomial-time algorithms are available, thus we could study large systems with high accuracy. Depending on the fraction of negatively and positively weighted edges in the lattice, a continuous phase transition can be identified, whose characterizing critical exponents we have estimated by a finite-size scaling analyses of the numerically obtained data. We observe a strong change of the universality class with respect to standard directed percolation, as well as with respect to undirected negative-weight percolation. Furthermore, the relation to directed polymers in random media is illustrated.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: This paper is devoted to study the phase space analysis of isotropic and homogenous universe model by taking a noninteracting mixture of electromagnetic and viscous radiating fluids whose viscous pressure satisfies a nonlinear version of the Israel-Stewart transport equation. We establish an autonomous system of equations by introducing normalized dimensionless variables. In order to analyze stability of the system, we find corresponding critical points for different values of the parameters. We also evaluate power-law scale factor whose behavior indicates different phases of the universe model. It is concluded that bulk viscosity as well as electromagnetic field enhances the stability of accelerated expansion of the isotropic and homogeneous universe model.

Young children's perspectives of outdoor pedagogical spaces: animated and entangled becomings
Creators: name: Merewether, Jane Rebecca
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis-by-publication charts animated and entangled becomings emerging out of encounters in outdoor spaces at two early learning centres in Perth, Western Australia. Deploying multimodal and multiperspectival research approaches used by the educators of Reggio Emilia (Davies, 2014a; Fleet, Patterson, & Robertson, 2006, 2012, 2017; Giamminuti, 2013; Giudici, Rinaldi, & Krechevsky, 2001; Pacini-Ketchabaw, Nxumalo, Kocher, Elliot, & Sanchez, 2015) and the Mosaic approach (Clark & Moss, 2001; Clark, 2017), the research which contributes to the thesis assemblage began with an intent to explore ways of seeking the perspectives of young children whose communication often does not rely on words. In that process, however, the children brought the author's attention to the forces of the materials in the spaces, highlighting the intra-action (Barad, 2007) of human and nonhuman matter. The thesis, therefore, moves from a predominantly sociocultural worldview into one increasingly informed by theories of new materialism and posthumanism. The thesis follows a shift from conventional thematic analysis into experimentations with diffractive analysis (Barad, 2007; Haraway, 1992), leading to a proposal of a "murmurative diffraction" approach to research. Throughout the thesis, children's sensitivity to the liveliness to the world, revealed through their animation of materials, objects and things, is a constant refrain. The implications of this study for researchers and teachers in educational settings in a time of unprecedented environmental devastation is to ensure we are attentive to the perspectives of human and nonhumans. Educational settings are an assemblage of intra-active human and nonhuman materials in which humans are not the only custodians of knowing (Barad, 2007). This needs researchers and teachers to be open and alert to the intra-actions that may occur, including children's "enchanted animism" and attentiveness to the surrounding materiality. It requires flexible approaches which recognise that researching and teaching are always becoming with (Haraway, 2008) the materials around us.
Logarithmic corrections to black hole entropy from Kerr/CFT

description: It has been shown by A. Sen that logarithmic corrections to the black hole area-entropy law are entirely determined macroscopically from the massless particle spectrum. They therefore serve as powerful consistency checks on any proposed enumeration of quantum black hole microstates. Sen's results include a macroscopic computation of the logarithmic corrections for a five-dimensional near extremal Kerr-Newman black hole. Here we compute these corrections microscopically using a stringy embedding of the Kerr/CFT correspondence and find perfect agreement.

Unconventional next nearest neighbor resonance coupling and states flipping mechanism in degenerate optical microcavities

description: We report a specially configured non-Hermitian optical microcavity, imposing spatially imbalanced gain-loss profile, to host an exclusively proposed next nearest neighbor resonances coupling scheme. Adopting scattering matrix (S-matrix) formalism, the effect of interplay between such proposed resonance interactions and the incorporated non-Hermiticity in the microcavity is analyzed drawing a special attention to the existence of hidden singularities, namely exceptional points (EPs); where at least two coupled resonances coalesce. We establish adiabatic flip-of-states phenomena of the coupled resonances in the complex frequency plane (k-plane) which is essentially an outcome of the fact that the respective EP is being encircled in system parameter plane. Encountering such multiple EPs, the robustness of flip-of-states phenomena have been analyzed via continuous tuning of coupling parameters along a special hidden singular line which connects all the EPs in the cavity. Such a numerically devised cavity, incorporating the exclusive next neighbor coupling scheme, have been designed for the first time to study the unconventional optical phenomena in the vicinity of EPs.
