description: This thesis investigates the information culture of an international non-governmental organisation in Bangladesh. The study includes the perspectives of development and aid workers in the country by exploring their information ecosystem and mapping these onto the Information Culture Framework by Oliver & Foscarini (2020). The research finds that cultural norms and different configurations of large-scale development and aid work shape ideas about the creation, maintenance, evaluation and disposition of information. This study animates the cultural values, communication processes, and information systems through which information, physical materials, records, and workers coalesce to provide aid to different communities on a large scale.

description: While quantum speed-up in solving certain decision problems by a fault-tolerant universal quantum computer has been promised, a timely research interest includes how far one can reduce the resource requirement to demonstrate a provable advantage in quantum devices without demanding quantum error correction, which is crucial for prolonging the coherence time of qubits. We propose a model device made of locally-interacting multiple qubits, designed such that simultaneous single-qubit measurements on it can output probability distributions whose average-case sampling is classically intractable, under similar assumptions as the sampling of non-interacting bosons and instantaneous quantum circuits. Notably, in contrast to these previous unitary-based realizations, our measurement-based implementation has two distinctive features. (i) Our implementation involves no adaptation of measurement bases, leading output probability distributions to be generated in constant time, independent of the system size. Thus, it could be implemented in principle without quantum error correction. (ii) Verifying the classical intractability of our sampling is done by changing the Pauli measurement bases only at certain output qubits. Our usage of random commuting quantum circuits in place of computationally universal circuits allows a unique unification of sampling and verification, so that they require the same physical resource requirements in contrast to the more demanding verification protocols seen elsewhere in the literature.

description: The fundamental phenomenon of Bose-Einstein Condensation (BEC) has been observed in different systems of real and quasi-particles. The condensation of real particles is achieved through a major reduction in temperature while for quasi-particles a mechanism of external injection of bosons by irradiation is required. Here, we present a novel and universal approach to enable BEC of quasi-particles and to corroborate it experimentally by using magnons as the Bose-particle model system. The critical point to this approach is the introduction of a disequilibrium of magnons with the phonon bath. After heating to an elevated temperature, a sudden decrease in the temperature of the phonons, which is approximately instant on the time scales of the magnon system, results in a large excess of incoherent magnons. The consequent spectral redistribution of these magnons triggers the Bose-Einstein condensation.
description: In contrast to the previous version additional information has been added. The chemical potential was derived from BLS measurements, the influence of the spin Seebeck effect is discussed more extensively in the Supplement with respect to the theoretical model and the rapid cooling has been realized in Au/Al/YIG structures where no substantial contribution of the spin Seebeck effect is expected

description: Human languages are context-dependent by nature. There are many context-related system errors in current natural language understanding and generation models. This research considers contextual information and studies various context-dependent tasks to fill this gap. We first investigate the role of context in subword segmentation for neural machine translation. Then we explore context-dependent natural language understanding in dialogue systems. Finally, we denote the format, wording, and genre of the input sentences as meta context. We utilize the meta context to synthesize unlabeled in-domain data to advance text classification tasks under various settings.

description: Multi-Domain Recommendation (MDR) has gained significant attention in recent years, which leverages data from multiple domains to enhance their performance concurrently.However, current MDR models are confronted with two limitations. Firstly, the majority of these models adopt an approach that explicitly shares parameters between domains, leading to mutual interference among them. Secondly, due to the distribution differences among domains, the utilization of static parameters in existing methods limits their flexibility to adapt to diverse domains. To address these challenges, we propose a novel model Hyper Adapter for Multi-Domain Recommendation (HAMUR). Specifically, HAMUR consists of two components: (1). Domain-specific adapter, designed as a pluggable module that can be seamlessly integrated into various existing multi-domain backbone models, and (2). Domain-shared hyper-network, which implicitly captures shared information among domains and dynamically generates the parameters for the adapter. We conduct extensive experiments on two public datasets using various backbone networks. The experimental results validate the effectiveness and scalability of the proposed model.

description: For a quantum particle with a single degree of freedom, we derive preparational sum and product uncertainty relations satisfied by $N$ linear combinations of position and momentum observables. The state-independent bounds depend on their degree of incompatibility defined by the area of a parallelogram in an $N$-dimensional coefficient space. Maximal incompatibility occurs if the observables give rise to regular polygons in phase space. We also conjecture a Hirschman-type uncertainty relation for N observables linear in position and momentum, generalizing the original relation which lower-bounds the sum of the position and momentum Shannon entropies of the particle.

description: This research conceptualises, develops and applies novel computer vision and deep learning software to enhance our understanding of insect pollinator behaviour in agriculture and ecology. Pollinators underpin around a third of food for human consumption, and insects, especially bees, are essential for global sustainability. Improving our understanding of insect pollination through monitoring is required for enhancing crop production and food security. Whilst existing methods of pollination monitoring are manual, digital technologies I introduce automatically capture and analyse measures of flower visitation by insects. This solution enables data-driven crop pollination management and transforms insect biodiversity monitoring.

Ergodicity breaking transition in a glassy soft sphere system at small but non-zero temperatures

description: While the glass transition at non-zero temperature seems to be hard to access for experimental, theoretical, or simulation studies, jamming at zero temperature has been explored in great detail. It is a widely discussed question whether this athermal jamming transition is related to the glass transition. Motivated by the exploration of the energy landscape that has been successfully used to describe athermal jamming, we introduce a new method to determine whether the configuration space of a soft sphere system can be explored within a reasonable timescale or not, i.e., whether the system is ergodic or effectively non-ergodic. While in case of athermal jamming for a given random starting configuration only the local energy minimum is determined, we allow the thermally excited crossing of energy barriers. Interestingly, we observe that a transition exists where the system becomes effectively non-ergodic if the density is increased. In the limit of small but non-zero temperatures the density where the ergodicity breaking transition occurs approaches a value that is independent of temperature and below the transition density of athermal jamming. This confirms recent computer simulation studies where athermal jamming occurs deep inside the glass phase. In addition, with our method we determined the critical behavior of the ergodicity breaking transition and show that it is in the universality class of directed percolation. Therefore, our approach not only makes the transition from an ergodic to an effectively non-ergodic systems easily accessible and helps to reveal its universality class but also shows that it is fundamentally different from athermal jamming.

description: An ultra-high throughput low-density parity check (LDPC) decoder with an unrolled full-parallel architecture is proposed, which achieves the highest decoding throughput compared to previously reported LDPC decoders in the literature. The decoder benefits from a serial message-transfer approach between the decoding stages to alleviate the well-known routing congestion problem in parallel LDPC decoders. Furthermore, a finite-alphabet message passing algorithm is employed to replace the variable node update rule of the standard min-sum decoder with look-up tables, which are designed in a way that maximizes the mutual information between decoding messages. The proposed algorithm results in an architecture with reduced bit-width messages, leading to a significantly higher decoding throughput and to a lower area as compared to a min-sum decoder when serial message-transfer is used. The architecture is placed and routed for the standard min-sum reference decoder and for the proposed finite-alphabet decoder using a custom pseudo-hierarchical backend design strategy to further alleviate routing congestions and to handle the large design. Post-layout results show that the finite-alphabet decoder with the serial message-transfer architecture achieves a throughput as large as 588 Gbps with an area of 16.2 mm$^2$ and dissipates an average power of 22.7 pJ per decoded bit in a 28 nm FD-SOI library. Compared to the reference min-sum decoder, this corresponds to 3.1 times smaller area and 2 times better energy efficiency.

title: Critical practices of place : decolonisation & reinhabitation
Creators: name: Orchard, CM
Publisher: name: University of Tasmania
Year: 2022

description: The exegesis and exhibition illustrate a sense-making process of understanding who I am - in time/place - through an embodied process of becoming more critically entangled or attendant with my relationships. These relationships are principally with the storied colonial past of the Eastern Riverina and my own family (human and other-than-human). This critical process of enacting decolonisation and reinhabitation provides insider-knowledge to a point-in-time in the Australian national dialogue on the intergenerational effects of colonialism through a personal account of that interface. This is particularly important as the work co-emerges with a deepening understanding of the catastrophic impacts of anthropogenic climate change, Australia’s worst bushfire season on record, prolonged drought, increasing political partisanship, growing race tensions, rising income inequality and a global pandemic. The exegesis foregrounds the recounting of personal experiences through troubled-times presented through a predominantly chronological suite of relational narratives. These narratives illustrate a sense-making process on the central thematic question ‘how do I live well with my total environments’, or, ‘how to live well in a world worth living in’. This unfolding takes place in the exegesis through hyperlinks backwards and forwards in time mirroring the exhibition works eminent exploration of relationships outside colonial-chronological time/place understanding. This exploration of time operates as a critical-reflective/reflexive process of enactment/embodiment that centres around my own emerging cultural understandings of intergenerational thinking, belonging and identity. This is explored as recovering the knowledge of my ancestors, making kin, and engaging with critical questions of what kind of ancestor I want to be – and setting that path meaningfully in motion. Both the exegesis and exhibition components utilise a methodological weave. Four strands are woven into each other to hold each other meaningfully in tension to strengthen the rope through the relationship of each. These strands are (1) Creative-practice research, (2) Autoethnography, (3) Indigenist Standpoint Theory, and, (4) Critical Pedagogy. Understanding the use of a multi-method research paradigm, but also the visual of the weave provides useful visual allegory for a new researcher method, a Critical Practice of Place. The research offers a series of findings of ways others might manifest their own deepening connections to place/time located in an exploration of their own belonging, identity, and relationships. This is through a new methodological weave, through a complex definition of Care, and through creative practice - iteration. It also presents a series of findings that illustrate the central premise that carries through the research, that there is always more to know, but there is always limits to knowing - and in reflection on this presents a series of future research opportunities.

description: The presence of dust in spiral galaxies affects the ability of photometric decompositions to retrieve the parameters of their main structural components. For galaxies in an edge-on orientation, the optical depth integrated over the line-of-sight is significantly higher than for those with intermediate or face-on inclinations, so it is only natural to expect that for edge-on galaxies, dust attenuation should severely influence measured structural parameters. In this paper, we use radiative transfer simulations to generate a set of synthetic images of edge-on galaxies which are then analysed via decomposition. Our results demonstrate that for edge-on galaxies, the observed systematic errors of the fit parameters are significantly higher than for moderately inclined galaxies. Even for models with a relatively low dust content, all structural parameters suffer offsets that are far from negligible. In our search for ways to reduce the impact of dust on retrieved structural parameters, we test several approaches, including various masking methods and an analytical model that incorporates dust absorption. We show that using such techniques greatly improves the reliability of decompositions for edge-on galaxies.

description: When users do not understand how machine learning models arrive at their outcomes, these models are opaque to the users. Providing explanations for the outcomes of these models is deemed an important step in making them transparent to users. In this thesis, we consider the explanation process as a two-step problem. The first step is to understand the feature attributions of the model outcome, and the second step is to incorporate these features with general human interpretability to form a comprehensible explanation. This thesis firstly aims to improve the stability of feature attributions and algorithmic efficiency, while maintaining the faithfulness to the underlying machine learning models; and lastly draw upon the research in philosophy, psychology and cognitive science, and generate human-interpretable explanations.

description: We study the appearance of structures in the decay of the $B^-$ into $K^- π^- D_{s0}^+(2317)$ and $K^- π^- D_{s1}^+(2460)$ final states by forming invariant mass distributions of $π^- D_{s0}^+$ and $π^- D_{s1}^+$ pairs, respectively. The structure in the distribution is associated to the kinematical triangle singularity that appears when the $B^- \to K^- K^{*\,0} D^0$ ($B^- \to K^- K^{*\,0} D^{*\,0}$) decay process is followed by the decay of the $K^{*\,0}$ into $π^- K^+$ and the subsequent rescattering of the $K^+ D^0$ ($K^+ D^{*\,0}$) pair forming the $D_{s0}^+(2317)$ ($D_{s1}^+(2460)$) resonance. We find this type of non-resonant peaks at 2850 MeV in the invariant mass of $π^- D_{s0}$ pairs from $B^- \to K^- π^- D_{s0}^+(2317)$ decays and around 3000 MeV in the invariant mass of $π^- D_{s1}^+$ pairs from $B^- \to K^- π^- D_{s1}^+(2460)$ decays. By employing the measured branching ratios of the $B^- \to K^- K^{*\,0} D^0$ and $B^- \to K^- K^{*\,0} D^{*\,0}$ decays, we predict the branching ratios for the processes $B^-$ into $K^- π^-D_{s0}^+(2317)$ and $K^- π^- D_{s1}^+(2460)$, in the vicinity of the triangle singularity peak, to be about $8\times10^{-6}$ and $1\times 10^{-6}$, respectively. The observation of this reaction would also give extra support to the molecular picture of the $D_{s0}^+(2317)$ and $D_{s1}^+(2460)$.

description: Matter bounces refer to scenarios wherein the universe contracts at early times as in a matter dominated epoch until the scale factor reaches a minimum, after which it starts expanding. While such scenarios are known to lead to scale invariant spectra of primordial perturbations after the bounce, the challenge has been to construct completely symmetric bounces that lead to a tensor-to-scalar ratio which is small enough to be consistent with the recent cosmological data. In this work, we construct a model involving two scalar fields (a canonical field and a non-canonical ghost field) to drive the symmetric matter bounce and study the evolution of the scalar perturbations in the model. If we consider the scale associated with the bounce to be of the order of the Planck scale, the model is completely described in terms of only one parameter, viz the value of the scale factor at the bounce. We evolve the scalar perturbations numerically across the bounce and evaluate the scalar power spectra after the bounce. We show that, while the scalar and tensor perturbation spectra are scale invariant over scales of cosmological interest, the tensor-to-scalar ratio proves to be much smaller than the current upper bound from the observations of the cosmic microwave background anisotropies by the Planck mission. We also support our numerical analysis with analytical arguments.

description: Visual perception is an essential cognitive process. Recent research has focused on understanding visual perception through the development of intelligent systems. Designing these systems require accurate estimation of gaze direction. Even with significant progress in the past few years, automatic gaze estimation still remains challenging especially due to the constrained environment based data acquisition setup. To overcome the limitation, this research attempts to develop automatic methods that advance the algorithm for gaze estimation in an unconstrained environment with limited supervision. The proposed methods arising from this thesis have potential applications in gaze based user interfaces and behavioural studies.

description: We consider the baker's map $B$ on the unit square $X$ and an open convex set $H\subset X$ which we regard as a hole. The survivor set $\mathcal J(H)$ is defined as the set of all points in $X$ whose $B$-trajectories are disjoint from $H$. The main purpose of this paper is to study holes $H$ for which $\dim_H \mathcal J(H)=0$ (dimension traps) as well as those for which any periodic trajectory of $B$ intersects $\overline H$ (cycle traps). We show that any $H$ which lies in the interior of $X$ is not a dimension trap. This means that, unlike the doubling map and other one-dimensional examples, we can have $\dim_H \mathcal J(H)>0$ for $H$ whose Lebesgue measure is arbitrarily close to one. Also, we describe holes which are dimension or cycle traps, critical in the sense that if we consider a strictly convex subset, then the corresponding property in question no longer holds. We also determine $δ>0$ such that $\dim_H \mathcal J(H)>0$ for all convex $H$ whose Lebesgue measure is less than $δ$. This paper may be seen as a first extension of our work begun in [3, 4, 6, 7, 13] to higher dimensions.

description: A new gas puff imaging (GPI) diagnostic has been developed on the HL-2A tokamak to study two-dimensional plasma edge turbulence in poloidal vs. radial plane. During a discharge, neutral helium or deuterium gas is puffed at the edge of the plasma through a rectangular multi-capillary nozzle to generate a gas cloud on the observing plane. Then a specially designed telescope and a high-speed camera are used to observe and photograph the emission from the neutral gas cloud. The brightness and contrast in the 2-D poloidal vs. radial frames reveal the structures and movements of the turbulence. The diagnostic was put into the first experiment during the latest campaign and successfully captured blob structures of different shapes and sizes in scrape-off layer (SOL).

description: Elemental abundances can be determined from stellar spectra, making it possible to study galactic formation and evolution. Accurate atomic data is essential for the reliable interpretation and modeling of astrophysical spectra. In this work, we perform laboratory studies on neutral aluminium. This element is found, for example, in young, massive stars and it is a key element for tracing ongoing nucleosynthesis throughout the Galaxy. The near-infrared (NIR) wavelength region is of particular importance, since extinction in this region is lower than for optical wavelengths. This makes the NIR wavelength region a better probe for highly obscured regions, such as those located close to the Galactic center. We investigate the spectrum of neutral aluminium with the aim to provide oscillator strengths (f-values) of improved accuracy for lines in the NIR and optical regions (670 - 4200 nm). Measurements of high-resolution spectra were performed using a Fourier transform spectrometer and a hollow cathode discharge lamp. The f-values were derived from experimental line intensities combined with published radiative lifetimes. We report oscillator strengths for 12 lines in the NIR and optical spectral regions, with an accuracy between 2 and 11%, as well as branching fractions for an additional 16 lines.

description: This thesis systematically analyses blockchain sharding, a promising approach for scaling blockchain protocols. Based on the systematic analysis, we formalised and improved two over-looked primitives in blockchain sharding protocols, namely shard allocation and decentralised randomness beacon (DRB), and suggested countermeasures against security issues in cross-chain 51% attacks and atomic swaps. We provided formal security proofs and experimental evaluations on the proposed constructions and countermeasures, demonstrating their security and practicality.
title: Fishing for data : using krill fishery data to expand krill research
Creators: name: Pavez, CSA
Publisher: name: University of Tasmania

description: Antarctic krill (Euphausia superba) are the most abundant pelagic Antarctic crustacean. This large abundance has led to the expansion of the krill fishery to the point that today it is one of the largest fisheries in the world. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) regulates the Southern Ocean fisheries, including the krill fishery, by using the best available science to determine, and adjust, appropriate catch limits. Currently, data collected on board fishing vessels are primarily used to develop processes for optimising management strategies and determining catch limits. However, with expected climatic changes and increasing fishery pressure, expanding the capacity of the fishery data for use in biological and modelling analyses is crucial to better advise CCAMLR’s ecosystem-based management strategies. The studies within this thesis examined krill fishery data, and current modelling strategies used by CCAMLR, to identify the research potential of CCAMLR’s resources for the effective conservation of the krill population. Following the general introduction, this thesis presents four data chapters: In chapter 2, fishery data were used to reproduce results from published investigations that utilized research vessel data. It was determined that both data types are comparable for exploring variability in krill populations and can be analysed collectively for locations or seasons with sparse data availability. In chapter 3, fishing activities that occurred within narrow spatial and temporal windows of one another were examined to evaluate catch compositions and determine their external influencers. Overall, sample size is the biggest contributor to observed composition variability, and as a result, a minimum of 200 krill samples from a harvest should be collected for an accurate representation of the population. In chapter 4, the effects of moonlight on swarm formation and krill movement through the water column were investigated using fishery harvesting depths. The findings show a promising link between moonlight and harvesting efforts, possibly caused by changes in swarm formation as a response to a full moon. And in chapter 5, the proportional recruitment model used by CCAMLR for krill stock assessments was evaluated. Testing of the model highlighted deficiencies for scenarios with large variations in recruitment. Two alternative methods are presented for modelling krill recruitment. These models can support a wider range of scenarios, such as years of low recruitment. This thesis highlights that krill fishery data are essential to not only improve our current understanding of krill behaviour, but also to enhance management strategies in the face of expected future climate and harvesting challenges.

description: We study two identical fermions, or two hard-core bosons, in an infinite chain and coupled to phonons by interactions that modulate their hopping as described by the Peierls/Su-Schrieffer-Heeger (SSH) model. We show that exchange of phonons generates effective nearest-neighbor repulsion between particles and also gives rise to interactions that move the pair as a whole. The two-polaron phase diagram exhibits two sharp transitions, leading to light dimers at strong coupling and the flattening of the dimer dispersion at some critical values of the parameters. This dimer (quasi)self-trapping occurs at coupling strengths where single polarons are mobile. This illustrates that, depending on the strength of the phonon-mediated interactions, the coupling to phonons may completely suppress or strongly enhance quantum transport of correlated particles.

Flavor Non-universality Gauge Interactions and Anomalies in B-Meson Decays

description: Motivated by flavor non-universality and anomalies in semi-leptonic B-meson decays, we present a general and systematic discussion about how to construct anomaly-free $U(1)'$ gauge theories based on an extended standard model with only three right-handed neutrinos. If all standard model fermions are vector-like under this new gauge symmetry, the most general family non-universal charge assignments, $(a,b,c)$ for three-generation quarks and $(d,e,f)$ for leptons, need satisfy just one condition to be anomaly-free, $3(a+b+c)=-(d+e+f)$. Any assignment can be linear combinations of five independent anomaly-free solutions. We also illustrate how such models can generally lead to flavor-changing interactions and easily resolve the anomalies in B-meson decays. Probes with $B_s-\bar{B}_s$ mixing, decay into $τ^\pm$, dilepton and dijet searches at colliders are also discussed.

description: We explicitly determine the values of reduced cyclotomic periods of order $2^m$, $m\ge 4$, for finite fields of characteristic $p\equiv 3$ or $5\pmod{8}$. These evaluations are applied to obtain explicit factorizations of the corresponding reduced period polynomials. As another application, the weight distributions of certain irreducible cyclic codes are described.

subject: Autonomous agents and multiagent systems

description: Teams of Artificially Intelligent agents can more effectively achieve their goals by learning to cooperate. Methods for learning cooperation can be centralised or decentralised but the trade-offs of applying these methods are not well understood. This thesis conducts an in-depth analysis of different learning methods. It introduces a new multi-agent task that facilitates the study of complex cooperation and implements it as part of a reusable experimental platform. It uses the platform to conduct a systematic comparison of centralised and decentralised learning, providing new insights into their trade-offs, and presents a theoretical model that generalises the findings to new contexts.
