Journaling: a path to exegesis in creative research
Creators: name: Hecq, Dominique
Publisher: name: Swinburne
Year: 2024

description: Despite the relatively recent debate that unfolds in Special Issue 14 of TEXT, practice-led research remains a reasonably vexed topic. Writer and academic Scott Brook shares in his introduction of that special issue how, at a session on practice-led research, he noticed ‘a clear distinction was established between discussions aimed at establishing the legitimacy of creative works as research, and discussions on how artists in the university can establish a “research practice”' (Brook 2012). Biggs and Büchler continue this debate with examples of similar development overseas, where even conformism to the conventions of academic research may not have impactful outcomes for the artists (Biggs & Büchler 2012). This is because, as Biggs and Büchler suggest, research outputs inclined to follow academia may not be relevant or important to the wider community. Exegesis in practice-led research positions itself between the creative work and the audience in that it frames practice. But where is the practitioner who is both an artist and academic positioned? Exegesis helps answer this question by encouraging the practitioner to establish their own research practice, where creative practice continues to play its dynamic role. When practice-led research outputs comprise a creative artefact and an exegesis, it is crucial for the practitioner to adopt journaling to capture evidence of a self that evolves with practice and the research.

description: URhGe is a ferromagnetic superconductor with a distinctive magnetic behavior. In a field applied parallel to the b-axis and perpendicular to the easy axis, URhGe exhibits an abrupt orientational transition of the magnetization with a reentrant superconducting phase emerging close to the transition field. We develop a theoretical description of the magnetic properties of URhGe by considering a spin model with competing magnetic anisotropies. The model is analyzed both analytically at zero temperature and with Monte Carlo simulations at finite temperatures. The constructed H-T phase diagram for a magnetic field parallel to the b-axis features a tricritical point on the line of phase transitions between the ferromagnetic Ising state and the paramagnetic phase. We also demonstrate that the asymptotic tricritical behavior of the order parameter and the correlation length is described by the mean-field critical exponents.

description: Background: There is widespread interkingdom signalling between insects and microbes. For example, microbes found in floral nectar may modify its nutritional composition and produce odorants that alter the floral odor bouquet which may attract insect pollinators. Mosquitoes consume nectar and can pollinate flowers. We identified microbes isolated from nectar of common tansy, Tanacetum vulgare, elucidated the microbial odorants, and tested their ability to attract the common house mosquito, Culex pipiens. Results: We collected 19 microbial isolates from T. vulgare nectar, representing at least 12 different taxa which we identified with 16S or 26S rDNA sequencing as well as by biochemical and physiological tests. Three microorganisms (Lachancea thermotolerans, Micrococcus lactis, Micrococcus luteus) were grown on culture medium and tested in bioassays. Only the yeast L. thermotolerans grown on nectar, malt extract agar, or in synthetic nectar broth significantly attracted Cx. pipiens females. The odorant profile produced by L. thermotolerans varied with the nutritional composition of the culture medium. All three microbes grown separately, but presented concurrently, attracted fewer Cx. pipiens females than L. thermotolerans by itself. Conclusions: Floral nectar of T. vulgare contains various microbes whose odorants contribute to the odor profile of inflorescences. In addition, L. thermotolerans produced odorants that attract Cx. pipiens females. As the odor profile of L. thermotolerans varied with the composition of the culture medium, we hypothesize that microbe odorants inform nectar-foraging mosquitoes about the availability of certain macro-nutrients which, in turn, affect foraging decisions by mosquitoes.

description: We present an enhanced method for the application of Gaussian Mixture Modelling (GMM) to the coherent WaveBurst (cWB) algorithm in the search for short-duration gravitational wave (GW) transients. The supervised Machine Learning method of GMM allows for the multi-dimensional distributions of noise and signal to be modelled over a set of representative attributes, which aids in the classification of GW signals against noise transients (glitches) in the data. We demonstrate that updating the approach to model construction eliminates bias previously seen in the GMM analysis, increasing the robustness and sensitivity of the analysis over a wider range of burst source populations. The enhanced methodology is applied to the generic burst all-sky short search in the LIGO-Virgo full third observing run (O3), marking the first application of GMM to the 3 detector Livingston-Hanford-Virgo network. For both 2- and 3- detector networks, we observe comparable sensitivities to an array of generic signal morphologies, with significant sensitivity improvements to waveforms in the low Quality factor parameter space at false alarm rates of 1 per 100 years. This proves that GMM can effectively mitigate blip glitches, which are one of the most problematic sources of noise for un-modelled GW searches. The cWB-GMM search recovers similar numbers of compact binary coalescence (CBC) events as other cWB post-production methods, and concludes on no new gravitational wave detection after known CBC events are removed.

description: Nonlinear Landau-Zener tunneling is an important nonlinear phenomenon. We propose to stimulate the nonlinear tunneling in a spin-orbit-coupled spinor Bose-Einstein condensate. The system provides an experimentally tunable nonlinearity as well as multiple avoided crossings with tunable gap size in nonlinear dispersion relations. The nonlinearity generates tilted cusp and loop structures around the avoided crossings, and the physical consequence of these nonlinear structures is the nonlinear Landau-Zener tunneling. The spin-momentum locking induced by the spin-orbit coupling leads to a time-resolved observation of the nonlinear tunneling by measuring atom populations.

Unpacking the complexity of packaging design interaction: developing a packaging knowledge tool for design practitioners
Creators: name: Wright, Emily Joy
Publisher: name: Swinburne
Year: 2024

description: This thesis presents the development of an online informational resource for packaging designers to better understand how consumers respond to their packaging designs. This resource, entitled the unpack knowledge tool, aims to literally 'unpack' the complexity that surrounds consumer response to packaging by making the theory accessible to design practice. The development of the unpack knowledge tool is comprised of three phases, the knowledge, the process and the outcome. The first phase, the knowledge, brings together the literature in the area and then proposes a conceptual framework around consumer response and packaging design. The second phase reports on the development of the unpack knowledge tool. This includes establishing an industry context, proposing a design strategy, developing the content and then synthesizing this into an interactive informational resource. The development of the tool required a series of research methods, including discussions with packaging industry leaders, interviews with packaging consumers as well as the application of design practice processes, including iterative design development, information design and interface design. The third phase, the outcome, presents the final tool prototype as well as the findings of a preliminary evaluation on how well designers can use and comprehend the tool. A series of recommendations for revising the tool are proposed based on the testing results. In conclusion, applications for the unpack knowledge tool as well as future research opportunities are discussed.

description: Degenerate Higher Order Scalar Tensor (DHOST) theories are the most general scalar-tensor theories whose Lagrangian depends on the metric tensor and a single scalar field and its derivatives up to second order. They propagate only one scalar degree of freedom, without being plagued by Ostrogradsky instabilities. This is achieved through certain degeneracies of the functions forming their Lagrangian. They generalise the Horndeski and beyond-Horndeski theories. Originally proposed to describe the late-time acceleration of the expansion of the universe, generalising the cosmological constant, they can also be used to build models of the early universe, to describe inflation or alternatives to standard inflation. In the late universe, they modify the standard Vainstein screening mechanism from Horndeski theories (which can have observable consequences) and are suited to build black hole models, featuring non-stealth Kerr black hole solutions. In this work their phenomenology is reviewed, looking at their basic properties, their parameterisations and classifications, focusing on solutions in the early and the late universe and at cosmological and astrophysical constraints.

Anomalous State Sequence Modeling to Enhance Safety in Reinforcement Learning

description: The deployment of artificial intelligence (AI) in decision-making applications requires ensuring an appropriate level of safety and reliability, particularly in changing environments that contain a large number of unknown observations. To address this challenge, we propose a novel safe reinforcement learning (RL) approach that utilizes an anomalous state sequence to enhance RL safety. Our proposed solution Safe Reinforcement Learning with Anomalous State Sequences (AnoSeqs) consists of two stages. First, we train an agent in a non-safety-critical offline 'source' environment to collect safe state sequences. Next, we use these safe sequences to build an anomaly detection model that can detect potentially unsafe state sequences in a 'target' safety-critical environment where failures can have high costs. The estimated risk from the anomaly detection model is utilized to train a risk-averse RL policy in the target environment; this involves adjusting the reward function to penalize the agent for visiting anomalous states deemed unsafe by our anomaly model. In experiments on multiple safety-critical benchmarking environments including self-driving cars, our solution approach successfully learns safer policies and proves that sequential anomaly detection can provide an effective supervisory signal for training safety-aware RL agents

We devised a concise and portable pulsed magnetic field generator that produces a 40 T field with a pulse duration of 2 ms. It is assembled using only off-the-shelf components and a homemade coil that leverages small computers, Raspberry Pi, and Python codes. It allows for straightforward modification for general purposes. As working examples, we show representative applications in condensed matter experiments of magnetoresistance, magnetization, and magnetostriction measurements for graphite, NdNi$_{2}$P$_{2}$, and NdCo$_{2}$P$_{2}$, respectively, with the maximum magnetic field of 41 T and the lowest temperature of 4.2 K.

description: We calculate the arrival direction distribution of ultra-high-energy cosmic rays (UHECRs) with a new suite of models of the Galactic magnetic field (GMF), assuming sources follow the large-scale structure of the Universe. Compared to previous GMF models, the amplitude of the dipole component of the UHECR arrival flux is significantly reduced. We find that the reduction is due to the accidentally coinciding position of the peak of the extragalactic UHECR flux and the boundary of strong flux demagnification due to the GMF toward the central region of the Galaxy. This serendipitous sensitivity of UHECR anisotropies to the GMF model will be a powerful probe of the source distribution as well as Galactic and extragalactic magnetic fields. Demagnification by the GMF also impacts visibility of some popular source candidates.

description: We study Ruelle-Pollicott resonances in translationally invariant quantum many-body lattice systems via spectra of a momentum-resolved operator propagator on infinite systems. Momentum dependence gives insight into the decay of correlation functions, showing that, depending on their symmetries, different correlation functions in general decay with different rates. Focusing on the kicked Ising model the spectrum seems to be typically composed of an annular random matrix like ring whose size we theoretically predict, and few isolated resonances. We identify several interesting regimes, including a mixing regime with a power-law decay of correlation functions. In that regime we also observe a huge difference in time-scales of different correlation functions due to an almost conserved operator. An exact expression for the singular values of the operator propagator is conjectured, showing that it becomes singular at a special point.

Publisher: name: Swinburne
Year: 2024

description: Aim: This paper presents a discussion of classification and regression tree analysis and its utility in nursing research. Background: Classification and regression tree analysis is an exploratory research method used to illustrate associations between variables not suited to traditional regression analysis. Complex interactions are demonstrated between covariates and variables of interest in inverted tree diagrams. Design: Discussion paper. Data sources: English language literature was sourced from eBooks, Medline Complete and CINAHL Plus databases, Google and Google Scholar, hard copy research texts and retrieved reference lists for terms including classification and regression tree* and derivatives and recursive partitioning from 1984-2013. Discussion: Classification and regression tree analysis is an important method used to identify previously unknown patterns amongst data. Whilst there are several reasons to embrace this method as a means of exploratory quantitative research, issues regarding quality of data as well as the usefulness and validity of the findings should be considered. Implications for Nursing Research: Classification and regression tree analysis is a valuable tool to guide nurses to reduce gaps in the application of evidence to practice. With the ever-expanding availability of data, it is important that nurses understand the utility and limitations of the research method. Conclusion: Classification and regression tree analysis is an easily interpreted method for modelling interactions between health-related variables that would otherwise remain obscured. Knowledge is presented graphically, providing insightful understanding of complex and hierarchical relationships in an accessible and useful way to nursing and other health professions.

description: Homogeneous planar superfluids exhibit a range of low-energy excitations that also appear in highly excited states like superfluid turbulence. In dilute gas Bose-Einstein condensates, the Jones- Roberts soliton family includes vortex dipoles and rarefaction pulses in the low and high velocity regimes, respectively. These excitations carry both energy and linear momentum, making their decay characteristics crucial for understanding superfluid dynamics. In this work, we develop the theory of planar soliton decay due to thermal effects, as described by the stochastic projected Gross-Pitaevskii theory of reservoir interactions. We analyze two distinct damping terms involving transfer between the condensate and the non-condensate reservoir: particle transfer that also involves energy and usually drives condensate growth, and number-conserving energy transfer. We provide analytical treatments for both the low and high velocity regimes and identify conditions under which either mechanism dominates. Our findings indicate that energy damping prevails at high phase space density. These theoretical results are supported by numerical studies covering the entire velocity range from vortex dipole to rarefaction pulse. We use interaction energy to characterize rarefaction pulses, analogous to the distance between vortices in vortex dipoles, offering an experimentally accessible test for finite temperature theory in Bose-Einstein condensates.

description: Exotic quantum order in kagome metals, i.e., quantum materials with a Fermi liquid parent state of electrons on a kagome lattice, has appeared as a vibrant emerging field of condensed matter physics. Already in a small kagome material subclass such as vanadium-based compounds $A$V$_3$Sb$_5$ ($A=$ K, Rb, Cs), the first wave of experimental exploration has brought about manifold evidence for hitherto largely elusive phenomena such as high-temperature charge ordering with orbital currents, nematic order, cascades of charge ordering transitions with hierarchies of ordering vectors, and unconventional superconductivity. We argue that kagome metals promise to be a prototypical ground for the non-equilibrium analysis of quantum order through time-dependent parameter control and manipulation. In particular, we propose to investigate the nematic character of kagome quantum order through light and strain pulses, as well as the nature of time-reversal symmetry breaking and chirality through properly polarized laser pulses.

We prove that the truncation error decreases exponentially with system size when the effective temperature of the mTPQ state is smaller than the target temperature, and otherwise, the error remains constant. We also show the discipline to set the mTPQ parameter by considering the trade-off between the error and the numerical cost.

description: Machine translation models are still inappropriate for translating chats, despite the popularity of translation software and plug-in applications. The complexity of dialogues poses significant challenges and can hinder crosslingual communication. Instead of pursuing a flawless translation system, a more practical approach would be to issue warning messages about potential mistranslations to reduce confusion. However, it is still unclear how individuals perceive these warning messages and whether they benefit the crowd. This paper tackles to investigate this question and demonstrates the warning messages' contribution to making chat translation systems effective.
Vapour hydrolysis of complex metal hydrides for mobile hydrogen storage and delivery

Subjects: subject: 39999 Chemical Sciences not elsewhere classified

description: The controlled vapour hydrolysis of metal hydrides has been investigated as a safe and predictable method to produce hydrogen for mobile applications and the products analysed by thermogravimetric analysis, infrared spectroscopy, and powder X-ray diffraction. A vapour hydrolysis cell was adapted from the design originally provided by Paul Brack and manufactured by Intelligent Energy Ltd. Vapour was created by water evaporation, sonification and using saturated salts solutions to generate humidity. Hydrogen was initially measured by water displacement and then through mass balance indicating that 459±0.05 cm3 H2 was generated from 0.2 g of LiAlH4 starting material equating to 97 % percentage yield. Analysis of the products of the LiAlH4 reaction indicated the formation of the layered double hydroxide, [LiAl2(OH)6]¬2CO3·3H2O and not production of the simple salts, LiOH and Al(OH)3, as predicted by the literature. The high level of hydration of the LDH and presence of carbonate indicated that the feed stream was contaminated with CO2 and that the highly hydrated product would be detrimental to the mobile hydrogen production process; restricting recyclability of the water carried. Synthesis in a glove box indicated that the hydroxide derivative of the LDH, [LiAl2(OH)6]¬OH·2H2O, could be prepared, but the water content remained significant, equating to 17 % of the carried weight. Thermogravimetric analysis showed that water was retained to 320 °C making mobile heating impractical. Mimicking the products by preparing different LDH salts containing different anions (SO42-, NO3-, Cl- and OH-) was attempted to determine if the level of hydration could be reduced by including additives . To minimise the amount of water required for the hydrolysis of LiAlH4, vapour hydrolysis was used in a flow reaction set up. Using steam hydrolysis generated a rate of hydrogen production of 4.83 cm3 H2 s-1 of LiAlH4, while using ultrasonic humidification generated a hydrogen production rate of 21 cm3 s-1, followed by a slow rate of 0.015 cm3 H2 s-1 as the reaction plateaus. Vapour hydrolysis of the lightweight metal hydrides LiAlH4, NaAlH4, NaH, CaH2, LiH have been investigated under flow conditions. A packed bed reactor was used to maximise gravimetric and volumetric energy density and control heat transfer from the hydrolysis of the hydride reactions. rates of 1.18, 0.766, 0.545, 0.603 and 1.11 cm3 H2 s-1 respectively, for each hydride, were achieved. Altering the packing density and water vapour flow rate achieved a target flow rate of 0.02 g s-1 kW-1 as defined by the DOE for direct delivery to PEM fuel cells.

description: Mitochondria are central organelles that coordinate a vast array of metabolic and biologic functions important for cellular health. Amino acids are intricately linked to the bioenergetic, biosynthetic, and homeostatic function of the mitochondrion and require specific transporters to facilitate their import, export, and exchange across the inner mitochondrial membrane. Here we review key cellular metabolic outputs of eukaryotic mitochondrial amino acid metabolism and discuss both known and unknown transporters involved. Furthermore, we discuss how utilization of compartmentalized amino acid metabolism functions in disease and physiological contexts. We examine how improved methods to study mitochondrial metabolism, define organelle metabolite composition, and visualize cellular gradients allow for a more comprehensive understanding of how transporters facilitate compartmentalized metabolism.

description: The use of data collection to support decision making through the reduction of uncertainty is ubiquitous in the management, operation, and design of building energy systems. However, no existing studies in the building energy systems literature have quantified the economic benefits of data collection strategies to determine whether they are worth their cost. This work demonstrates that Value of Information analysis (VoI), a Bayesian Decision Analysis framework, provides a suitable methodology for quantifying the benefits of data collection. Three example decision problems in building energy systems are studied: air-source heat pump maintenance scheduling, ventilation scheduling for indoor air quality, and ground-source heat pump system design. Smart meters, occupancy monitoring systems, and ground thermal tests are shown to be economically beneficial for supporting these decisions respectively. It is proposed that further study of VoI in building energy systems would allow expenditure on data collection to be economised and prioritised, avoiding wastage.

description: In industrial recommendation systems on websites and apps, it is essential to recall and predict top-n results relevant to user interests from a content pool of billions within milliseconds. To cope with continuous data growth and improve real-time recommendation performance, we have designed and implemented a high-performance batch query architecture for real-time recommendation systems. Our contributions include optimizing hash structures with a cacheline-aware probing method to enhance coalesced hashing, as well as the implementation of a hybrid storage key-value service built upon it. Our experiments indicate this approach significantly surpasses conventional hash tables in batch query throughput, achieving up to 90% of the query throughput of random memory access when incorporating parallel optimization. The support for NVMe, integrating two-tier storage for hot and cold data, notably reduces resource consumption. Additionally, the system facilitates dynamic updates, automated sharding of attributes and feature embedding tables, and introduces innovative protocols for consistency in batch queries, thereby enhancing the effectiveness of real-time incremental learning updates. This architecture has been deployed and in use in the bilibili recommendation system for over a year, a video content community with hundreds of millions of users, supporting 10x increase in model computation with minimal resource growth, improving outcomes while preserving the system's real-time performance.

description: Understanding efficient modifications to improve network functionality is a fundamental problem of scientific and industrial interest. We study the response of network dynamics against link modifications on a weakly connected directed graph consisting of two strongly connected components: an undirected star and an undirected cycle. We assume that there are directed edges starting from the cycle and ending at the star (master-slave formalism). We modify the graph by adding directed edges of arbitrarily large weights starting from the star and ending at the cycle (opposite direction of the cutset). We provide criteria (based on the sizes of the star and cycle, the coupling structure, and the weights of cutset and modification edges) that determine how the modification affects the spectral gap of the Laplacian matrix. We apply our approach to understand the modifications that either enhance or hinder synchronization in networks of chaotic Lorenz systems as well as Rössler. Our results show that the hindrance of collective dynamics due to link additions is not atypical as previously anticipated by modification analysis and thus allows for better control of collective properties.
Primordial magnetogenesis in a bouncing model with dark energy

description: We investigate primordial magnetogenesis within a quantum bouncing model driven by a scalar field, focusing on various non-minimal couplings between the electromagnetic field and the scalar field. We test three cases: no coupling, a Cauchy coupling with gradual decay, and a Gaussian coupling with rapid fall-off. By exploring these scenarios, we assess a wide range of coupling strengths across different scales. The scalar field, with an exponential potential, behaves as pressureless matter in the asymptotic past of the contracting phase, as stiff matter around the bounce, and as dark energy during the expanding phase. Our findings reveal that, among the tested cases, only the Gaussian coupling can explain the generation of primordial magnetic fields on cosmological scales.

description: This paper provides an enjoyable example through which several concepts of classical mechanics can be understood. We introduce an equation that models the motion of a cat in the presence of a person. The cat is considered as a point particle moving in a potential induced by the person. We demonstrate that this approach to the problem reproduces characteristic behaviors of these curious animals. For instance, the fact that cats do not typically come when they are called, or that they remain longer on the lap of their favorite person; even "zoomies" are reproduced (cats randomly run back and forth across the house). We use this model problem to explore topics of current research such as stochastic equations and periodically driven systems. The pedagogical value of this work and its potential use in teaching are discussed.

Re-designing the conference

description: I recently concluded the Americas Cultures-Based Innovation (CBI) Symposium, co-hosted by the Banff Centre in Calgary, Canada. Being the third time that I have co-organised a CBI Symposium, I now know that the design of its structure effectively achieves its intention, namely, to build deep relationships among its 15-20 participants. The undisputed fact of the love I feel for the last Symposium's fifteen participants, all within five days, prompts me to ask the question: Why are so many conferences based on the value of sharing ideas instead of deepening relationships among the participants?

description: Phytosterols are a class of lipid molecules present in plants that are structurally similar to cholesterol and have been widely utilized as cholesterol-lowering agents. However, the susceptibility of phytosterols to oxidation has led to concerns regarding their safety and tolerability. Phytosterol oxidation products (POPs) present in a variety of enriched and non-enriched foods can show pro-atherogenic and pro-inflammatory properties. Therefore, it is crucial to screen and analyze various phytosterol-containing products for the presence of POPs and ultimately design or modify phytosterols in such a way that prevents the generation of POPs and yet maintains their pharmacological activity. The main approaches for the analysis of POPs include the use of mass spectrometry (MS) linked to a suitable separation technique, notably gas chromatography (GC). However, liquid chromatography (LC)-MS has the potential to simplify the analysis due to the elimination of any derivatization step, usually required for GC-MS. To reduce the transformation of phytosterols to their oxidized counterparts, formulation strategies can theoretically be adopted, including the use of microemulsions, microcapsules, micelles, nanoparticles, and liposomes. In addition, co-formulation with antioxidants, such as tocopherols, may prove useful in substantially preventing POP generation. The main objectives of this review article are to evaluate the various analytical strategies that have been adopted for analyzing them. In addition, formulation approaches that can prevent the generation of these oxidation products are proposed.

description: Changing some of its parameters over time is a paradigmatic way of driving an otherwise isolated many-body quantum system out of equilibrium, and a vital ingredient for building quantum computers and simulators. Here, we further develop a recently proposed nonlinear response theory which is based on typicality and random-matrix methods, and which is applicable to a wide variety of such parametrically perturbed systems in and out of equilibrium: We derive analytical approximations of the characteristic response function for the two limiting cases of fast driving and of strong and short-ranged-in-energy driving. Furthermore, we work out implications and predictions for common applications, including finite-time quenches and time-dependent forcing that breaks conservation laws of the underlying undriven system. Finally, we verify all predictions by numerical examples and discuss the theory's scope and limitations.

description: The recent observation of high-energy neutrinos from the Galactic plane implies an abundant population of hadronic cosmic-ray sources in the Milky Way. We explore the role of the coronae of accreting stellar-mass black holes as such astroparticle emitters. We show that the particle acceleration and interaction timescales in the coronal region are tied to the compactness of the X-ray source. Thus, neutrino emission processes may similarly happen in the cores of active galactic nuclei and black hole X-ray binaries (XRB), despite of their drastically different masses and physical sizes. We apply the model to the well-measured XRB Cygnus X-1 and find that the cascaded gamma rays accompanying the neutrino emission naturally explain the GeV emission that only presents during the source's hard state, while the state-averaged gamma-ray emission explains the LHAASO observation above 20 TeV. We show that XRB coronae could contribute significantly to the Galactic cosmic-ray and Galactic plane neutrino fluxes. Our model predicts variable high-energy neutrino emission from bright Galactic XRBs that may be observed by IceCube and future neutrino observatories.
