description: Introduction

Qualitative studies often involve interviewing participants. The interviews are then transcribed into text from audio or video data. If there are many participants, it becomes cumbersome to read all the interviews and perform the required text analysis. One such study being conducted by the Department of Finance in the Faculty of Business and Law at Deakin University is seeking to understand the perceptions of employers, key workers, and other stakeholders regarding current and novel pathways to address the shortage of essential worker housing in regional areas in Australia. For this project, a total of 30 interviews were conducted.

Methods

To perform text analysis on the transcription of these interviews, we have used deep learning computational models. The text corpus of each group of stakeholders was summarized using the Bidirectional Encoder Representations from Transformers (BERT) and Generative Pre-Trained Transformer (GPT). The summaries created by these models were read by researchers to identify the common themes in the text.

Results

Using BERT and GPT has enabled the researcher to review the large corpus text in a very short time.  The researchers were able to investigate the perceptions of stakeholders on housing availability and affordability in regional areas in Australia. Finally, it was possible to identify the challenges and opportunities to create an affordable housing program for essential workers in regional Australia.

Conclusion

BERT and GPT have augmented the researcher's ability to perform text analysis and answer the research questions. The presentation will demonstrate the BERT and GPT models on sample text.

description: Consider a rational family of planar rational curves in a certain region of interest. We are interested in finding an approximation to the implicit representation of the envelope. Since exact implicitization methods tend to be very costly, we employ an adaptation of approximate implicitization to envelope computation. Moreover, by utilizing an orthogonal basis in the construction process, the computational times can be shortened and the numerical condition improved. We provide an example to illustrate the performance of our approach.

The position and the momentum operators of each of the groups generate basic Lie superalgebras, namely $sl(1/3)$, $osp(1/6)$ and $osp(3/2)$. The $sl(1/3)$-oscillators have finite energy spectrum and finite-dimensions. The $osp(1/6)$-oscillators are related to the para-Bose statistictics. The internal angular momentum $s$ of the $osp(3/2)$-oscillators takes no more than three (half)integer values. In a particular representation $s=1/2$.

description: We present N-body simulations of galaxy groups embedded in a common halo of matter. We study the influence of the different initial conditions upon the evolution of the group and show that denser configurations evolve faster, as expected. We then concentrate on the influence of the initial radial density profile of the common halo and of the galaxy distribution. We select two kinds of density distributions, a singular profile (modeled by a Hernquist distribution) and a profile with a flat core (modeled by a Plummer sphere). In all cases we witness the formation of a central massive object due to mergings of individual galaxies and to accretion of stripped material, but both its formation history and its properties depend heavily on the initial distribution. In Hernquist models the formation is due to a ``burst'' of mergings in the inner parts, due to the large initial concentration of galaxies in the center. The merging rate is much slower in the initial phases of the evolution of a Plummer distribution, where the contribution of accretion to the formation of the central object is much more important. The central objects formed within Plummer distributions have projected density profiles which are not in agreement with the radial profiles of observed brightest cluster members, unless the percentage of mass in the common halo is small. On the contrary the central object formed in initially cusped models has projected radial profiles in very good agreement with those of brightest cluster members, sometimes also showing luminosity excess over the $r^{1/4}$ law in the outer parts, as is observed in cD galaxies.

description: Transient stability assessment is a critical tool for power system design and operation. With the emerging advanced synchrophasor measurement techniques, machine learning methods are playing an increasingly important role in power system stability assessment. However, most existing research makes a strong assumption that the measurement data transmission delay is negligible. In this paper, we focus on investigating the influence of communication delay on synchrophasor-based transient stability assessment. In particular, we develop a delay aware intelligent system to address this issue. By utilizing an ensemble of multiple long short-term memory networks, the proposed system can make early assessments to achieve a much shorter response time by utilizing incomplete system variable measurements. Compared with existing work, our system is able to make accurate assessments with a significantly improved efficiency. We perform numerous case studies to demonstrate the superiority of the proposed intelligent system, in which accurate assessments can be developed with time one third less than state-of-the-art methodologies. Moreover, the simulations indicate that noise in the measurements has trivial impact on the assessment performance, demonstrating the robustness of the proposed system.
From UNSW Data Archives to UNSWorks – learnings from the ARDC Data Retention project

description: At UNSW, a significant volume of research data is hosted within the 'Data Archive', UNSW's solution for providing long-term end-of-project storage of research data. This data is typically closed access. As part of UNSW's involvement in the ARDC's 'Data Retention' initiative (aimed at enriching data collections and making them publicly accessible), a concerted effort was made to document and openly publish as much of this data as possible into UNSWorks, UNSW's Institutional Repository. In total, 176 data custodians of datasets within the Data Archive were contacted and offered assistance in making their specific datasets openly available in the repository. These engagements provided many insights, both positive and negative, around the awareness of, capability in, and general thoughts towards research data publishing. This presentation will share these insights and the patterns of behaviours of UNSW researchers when asked to consider publishing data from their archived collection. The presentation will also share how these findings could influence improve support by ResTech Services and the Library. The outcomes from this work strongly highlight the importance of considering and planning for publishing data at the outset of any research endeavour.

description: How do real graphs evolve over time? What are ``normal'' growth patterns in social, technological, and information networks? Many studies have discovered patterns in static graphs, identifying properties in a single snapshot of a large network, or in a very small number of snapshots; these include heavy tails for in- and out-degree distributions, communities, small-world phenomena, and others. However, given the lack of information about network evolution over long periods, it has been hard to convert these findings into statements about trends over time. Here we study a wide range of real graphs, and we observe some surprising phenomena. First, most of these graphs densify over time, with the number of edges growing super-linearly in the number of nodes. Second, the average distance between nodes often shrinks over time, in contrast to the conventional wisdom that such distance parameters should increase slowly as a function of the number of nodes (like O(log n) or O(log(log n)). Existing graph generation models do not exhibit these types of behavior, even at a qualitative level. We provide a new graph generator, based on a ``forest fire'' spreading process, that has a simple, intuitive justification, requires very few parameters (like the ``flammability'' of nodes), and produces graphs exhibiting the full range of properties observed both in prior work and in the present study. We also notice that the ``forest fire'' model exhibits a sharp transition between sparse graphs and graphs that are densifying. Graphs with decreasing distance between the nodes are generated around this transition point.

description: We investigate of a special dam optimal location at the Volga river in area of the Akhtuba left sleeve beginning (7 \, km to the south of the Volga Hydroelectric Power Station dam). We claim that a new water-retaining dam can resolve the key problem of the Volga-Akhtuba floodplain related to insufficient water amount during the spring flooding due to the overregulation of the Lower Volga. By using a numerical integration of Saint-Vacant equations we study the water dynamics across the northern part of the Volga-Akhtuba floodplain with taking into account its actual topography. As the result we found an amount of water $V_A$ passing to the Akhtuba during spring period for a given water flow through the Volga Hydroelectric Power Station (so-called hydrograph which characterises the water flow per unit of time). By varying the location of the water-retaining dam $ x_d, y_d $ we obtained various values of $V_A (x_d, y_d) $ as well as various flow spatial structure on the territory during the flood period. Gradient descent method provide us the dam coordinated with the maximum value of ${V_A}$. Such approach to the dam location choice let us to find the best solution, that the value $V_A$ increases by a factor of 2. Our analysis demonstrate a good potential of the numerical simulations in the field of hydraulic works.

For this purpose, we use regional aggregated data and esti-mate the capitalisation rate upon the entire sample and, in a second stage, splitting the sample according to the implementation regime applied by the different EU Member States (MSs), following the three options introduced by the CAP regulations (histori-cal, regional and hybrid model). We find that between 28 and 52 cents per Euro of additional subsidy capitalise into land prices in MSs that adopted the hybrid and the regional model, respectively. We find as well that subsidies do not capitalise in farm-land prices in MSs that adopted the historical model.

In this work we systematically reconstruct the logical implications of both methods on quantum black hole physics and provide the link between these two approaches. Our conclusions completely support our previous findings based solely on the WKB method: quantum black holes are effectively p-brane excitations and, consequently, no information loss paradox exists in this problem.

description: We realize the treatment of bound and continuum nuclear systems in the proximity of a three-body breakup threshold within the ab initio framework of the no-core shell model with continuum. Many-body eigenstates obtained from the diagonalization of the Hamiltonian within the harmonic-oscillator expansion of the no-core shell model are coupled with continuous microscopic three-cluster states to correctly describe the nuclear wave function both in the interior and asymptotic regions. We discuss the formalism in detail and give algebraic expressions for the case of core+$n$+$n$ systems. Using similarity-renormalization-group evolved nucleon-nucleon interactions, we analyze the role of $^4$He+$n$+$n$ clustering and many-body correlations in the ground and low-lying continuum states of the Borromean $^6$He nucleus, and study the dependence of the energy spectrum on the resolution scale of the interaction. We show that $^6$He small binding energy and extended radii compatible with experiment can be obtained simultaneously, without recurring to extrapolations. We also find that a significant portion of the ground-state energy and the narrow width of the first $2^+$ resonance stem from many-body correlations that can be interpreted as core-excitation effects.

description: During a scan of the archival BATSE daily records covering the entire 9.1 years (TJD 8369-11690) of the BATSE operation, 3906 gamma-ray bursts (GRBs) have been detected. 2068 of these GRBs are previously known BATSE triggers while 1838 of them are new non-triggered bursts. It is important that all events were detected in the same type of data and were processed with the same procedure. Therefore these 3906 GRBs constitute a uniform sample. We have created a publically available electronic data base containing this sample. We describe the procedures of the data reduction, the selection of the GRB candidates, and the statistical tests for possible non-GRB contaminations. We also describe a novel test burst method used to measure the scan efficiency and the information obtained using the test bursts. Our scan decreases the BATSE detection threshold to ~0.1 photons/sec/cm2. As a first result, we show that the differential log N - log P distribution corrected for the detection efficiency extends to low brightnesses without any indication of a turn-over. Any reasonable extrapolation of the new log N - log P to lower brightnesses imply a rate of several thousands of GRBs in the Universe per year.

description: The beam coupling impedances of small discontinuities of an accelerator vacuum chamber have been calculated [e.g., S.S. Kurennoy, R.L. Gluckstern, and G.V. Stupakov, Phys. Rev. E 52, 4354 (1995)] for ultrarelativistic beams using the Bethe diffraction theory. Here we extend the results to an arbitrary beam velocity. The vacuum chamber is assumed to have an arbitrary, but uniform along the beam path, cross section. The longitudinal and transverse coupling impedances are derived in terms of series over cross-section eigenfunctions, while the discontinuity shape enters via its polarizabilities. Simple explicit formulas for two important particular cases - circular and rectangular chamber cross sections - are presented. The impedance dependence on the beam velocity exhibits some unusual features: for example, the reactive impedance, which dominates in the ultrarelativistic limit, can vanish at a certain beam velocity, or its magnitude can exceed the ultrarelativistic value many times. In addition, we demonstrate that the same technique, the field expansion into a series of cross-section eigenfunctions, is convenient for calculating the space-charge impedance of uniform beam pipes with arbitrary cross section.

description: RMIT is the first Australian university to go live with a dedicated commercial cloud supercomputing facility – RACE (RMIT AWS Cloud Supercomputing) by partnering with Amazon Web Services (AWS) and AARNet. RACE was officially launched in October 2022 and was quickly embraced by the RMIT research cohort. For the last six months, RACE has successfully onboarded more than 200 researchers and HDR students, allowing our researchers to test ideas and solutions up to 100 times faster than existing on-site servers.

The initial operation of RACE has identified three advantages and learned four lessons:
Three Advantages
1.Offer efficient and scalable cloud computing and HPC services to accelerate research excellence and empower RMIT researchers to secure competitive research grants.
2.Provide long-term sustainable cloud-based data storage options to enable RMIT to strengthen and comply with the Australian Code for the Responsible Conduct of Research (2018).
3.Deliver training, technical consultancies and expert services to lower technical barriers and uplift RMIT researchers' capabilities. This improves research efficiency and maximises funding opportunities.

Four Lessons
1.RACE success stories validate the needs.
2.Clear identification of benefits effectively demonstrates RACE values.
3.Building a cost-effective model beyond 2023 is vital.
4.Offering an adaptive and responsive platform, allows the RACE to better respond to current and future needs.

This presentation will detail the advantages of adopting the cloud-based computing approach and the lessons we learned on enabling research excellence by leveraging AWS cloud services.

description: Image registration (IR) is a fundamental task in image processing for matching two or more images of the same scene taken at different times, from different viewpoints and/or by different sensors. Due to the enormous diversity of IR applications, automatic IR remains a challenging problem to this day. A wide range of techniques has been developed for various data types and problems. However, they might not handle effectively very large images, which give rise usually to more complex transformations, e.g., deformations and various other distortions. In this paper we present a genetic programming (GP)-based approach for IR, which could offer a significant advantage in dealing with very large images, as it does not make any prior assumptions about the transformation model. Thus, by incorporating certain generic building blocks into the proposed GP framework, we hope to realize a large set of specialized transformations that should yield accurate registration of very large images.

description: The dynamics of slow landslide motion can predispose oversteepened and extended slide regions to debris-flow initiation. For more than 20 years, our real-time monitoring, combined with repeat high-precision GPS surveys, of the Cleveland Corral landslide complex, California, USA, reveals that debris flows initiate from slow-moving kinematic elements of this complex. Different slide elements move in different wet years, and all remain dormant in dry years. To explore controls on landslide- element kinematics, we use triaxial testing to define the critical state behavior of the landslide material, and use a large-diameter sampling ring to determine in situ material porosities in both extensional and compressional regions of the slide complex. Regions undergoing extension contain materials looser than their critical state, potentially aiding liquefaction and debris-flow mobilization from shallow, secondary slides. Although intense rainfall serves as a trigger for debris-flow initiation, slow deformation of the larger landslide promotes debris-flow formation by oversteeepening toe and lateral margins and by preferentially extending, and effectively loosening, material in these steep regions.

description: Lipkin model of arbitrary particle-number N is studied in terms of exact differential-operator representation of spin-operators from which we obtain the low-lying energy spectrum with the instanton method of quantum tunneling. Our new observation is that the well known quantum phase transition can also occur in the finite-N model only if N is an odd-number. We furthermore demonstrate a new type of quantum phase transition characterized by level-crossing which is induced by the geometric phase interference and is marvelously periodic with respect to the coupling parameter. Finally the conventional quantum phase transition is understood intuitively from the tunneling formulation in the thermodynamic limit.

description: The evolution of quantum coherences comes with a set of conservation laws provided that the Hamiltonian governing this evolution conserves the spin-excitation number. At that, coherences do not intertwist during the evolution. Using the transmission line and the receiver in the initial ground state we can transfer the coherences to the receiver without interaction between them, { although the matrix elements contributing to each particular coherence intertwist in the receiver's state. } Therefore we propose a tool based on the unitary transformation at the receiver side to { untwist these elements and thus} restore (at least partially) the structure of the sender's initial density matrix. A communication line with two-qubit sender and receiver is considered as an example of implementation of this technique.

description: In this paper, we study the problem of sampling from a given probability density function that is known to be smooth and strongly log-concave. We analyze several methods of approximate sampling based on discretizations of the (highly overdamped) Langevin diffusion and establish guarantees on its error measured in the Wasserstein-2 distance. Our guarantees improve or extend the state-of-the-art results in three directions. First, we provide an upper bound on the error of the first-order Langevin Monte Carlo (LMC) algorithm with optimized varying step-size. This result has the advantage of being horizon free (we do not need to know in advance the target precision) and to improve by a logarithmic factor the corresponding result for the constant step-size. Second, we study the case where accurate evaluations of the gradient of the log-density are unavailable, but one can have access to approximations of the aforementioned gradient. In such a situation, we consider both deterministic and stochastic approximations of the gradient and provide an upper bound on the sampling error of the first-order LMC that quantifies the impact of the gradient evaluation inaccuracies. Third, we establish upper bounds for two versions of the second-order LMC, which leverage the Hessian of the log-density. We provide nonasymptotic guarantees on the sampling error of these second-order LMCs. These guarantees reveal that the second-order LMC algorithms improve on the first-order LMC in ill-conditioned settings.
Resolving the Mystery of X-ray Faint Elliptical Galaxies: Chandra X-ray Observations of NGC 4697

description: Chandra observations of the X-ray faint elliptical galaxy NGC 4697 resolve much of the X-ray emission (61% within one effective radius) into ~80 point sources, of which most are low mass X-ray binaries (LMXBs). These LMXBs provide the bulk of the hard emission and much of the soft emission as well. Of the remaining unresolved emission, it is likely that about half is from fainter LMXBs, while the other half (~23% of the total emission) is from interstellar gas. Three of the resolved sources are supersoft sources. In the outer regions of NGC 4697, eight of the LMXBs (about 25%) are coincident with candidate globular clusters, which indicates that globulars have a high probability of containing X-ray binaries compared to the normal stellar population. The X-ray luminosities (0.3-10 keV) of the resolved LMXBs range from ~5e37 to ~2.5e39 ergs/s. The luminosity function of the LMXBs has a "knee" at 3.2e38 ergs/s, which is roughly the Eddington luminosity of a 1.4 M_sun neutron star (NS); this knee might be useful as a distance indicator. The highest luminosity source has the Eddington luminosity of a ~20 M_sun black hole (BH). The presence of this large population of NS and massive BH stellar remnants in this elliptical galaxy shows that it (or its progenitors) once contained a large population of massive main sequence stars.

Evolutionary Constraints on the Long-period Subdwarf B Binary PG 1018-047

description: We have revisited the sdB+K-star long-period binary PG 1018-047 based on 20 new high-resolution VLT/UVES spectra that provided regular coverage over a period of more than 26 months. We refine the period and establish that the orbit is significantly eccentric ($P=751.6\pm1.9\rm{d}$ and $e=0.049\pm0.008$). A simultaneous fit derived from the narrow metal lines visible in the spectrum of the sdB star and the metal lines in the red part of the spectrum that originate from the companion provides the mass ratio, $M_{\rm MS}/M_{\rm sdB} = 1.52 \pm 0.04$, for the system. From an NLTE model atmosphere analysis of the combined spectra, we find $T_{\rm eff}$=29900$\pm$330K, log$g$= 5.65$\pm$0.06dex and log($n_{\rm He}$/$n_{\rm H}$)=-3.98$\pm$0.16dex for the primary, consistent with a B-type hot subdwarf star. The spectral contribution of the companion is consistent with a K5V-type star. With the companion having a mass of only $\sim$0.7$\rm M_{\odot}$ this system lies close to the boundary below which stable Roche-lobe overflow (RLOF) cannot be supported. To model the evolution of such a system, we have extended earlier MESA models towards lower companion masses. We find that both phase-dependent mass loss during RLOF, when 30 to 40\% of the available mass is lost through the outer Lagrange point, and phase-dependent mass loss during RLOF in combination with a circumbinary disk of maximum $M_{\rm CB} = 0.001\rm M_{\odot}$ could have formed the PG1018-047 binary system.

description: The debate on food security has highlighted the connection between periur-ban farming systems (PFS) and local food systems (LFS) for academic research. Several researchers have called for in-depth analysis of the participation and impact of farmers in LFS, and the systemic innovation perspective can provide relevant analysis of the sustainability of this agro-food system. The objective of the current study is to investi-gate the integration of PFS into LFS from the systemic innovation perspective, by ana-lysing systemic failures and merits that hinder or promote the contribution of PFS to LFS for farmers and commercial actors. The case study is the LFS of the urban Pisa region in central Italy. Results show that farmers there are adapting to urban pressure, which improves the sustainability of their farming practices. At the same time, com-mercial actors have a commercial opportunity to include local farmers in their eco-nomic strategy. Nevertheless, individual initiatives must be coordinated to support the sustainability of both LFS and PFS. This study thus developed an innovative method to identify systemic failures and merits for farmers and commercial actors to address sustainability strategies at the territorial level.
Managing research data at scale: addressing the growing data challenge together
Creators: name: Jung, David
Publisher: name: Zenodo
Year: 2023

description: The sector is currently grappling with significant data growth and the risks of managing research data at scale. Underlying this challenge are two problems: 1) there is low institutional maturity in the ability to assess this digital corpus that prevents extracting and acting on insights. 2) there is a limited understanding of institutional obligations and best practices of selective research content disposal and retention. This forms the basis of two, parallel, ARDC-funded projects that commenced in March 2023 (Business Intelligence & Reporting and Retention & Disposal). The expected output of the first project is a common taxonomy and reporting format for research data that satisfies local institutional needs while enabling sector-wide aggregation of data for benchmarking. The second project aims to develop a set of agreed best practices throughout the project lifecycle to decide on the retention and disposal of research data. This BoF session seeks wider sector input on the project outputs. The session also brings the two independent projects into the common perspective of tackling the issue of uncontrolled growth of digital content associated with research activities.

In this session, project outputs will be presented, then the floor will be opened to topics arising such as:

1. How does one practically implement the project outputs at their institution?
2. What is the long-term sustainability plan for the project outputs?
Quantum dynamics of two trapped bosons following infinite interaction quenches

description: We investigate the quantum dynamics of two identical bosons in a one-dimensional harmonic trap following an interaction quench from zero to infinite interaction strength and vice versa. For both quench scenarios, closed analytical expressions for the temporal evolution of the wave function as well as the Loschmidt Echo are found and the dynamics of the momentum distribution as well as the reduced single-particle density matrix are analyzed. We observe a crossover of these quantities between bosonic, "symmetrized" fermionic and fermionic properties. Furthermore, several combined quenches are analyzed as well.

description: We analyzed the evolution data of the Daya Bay reactor neutrino experiment in terms of short-baseline active-sterile neutrino oscillations taking into account the theoretical uncertainties of the reactor antineutrino fluxes. We found that oscillations are disfavored at $2.6σ$ with respect to a suppression of the $^{235}\text{U}$ reactor antineutrino flux and at $2.5σ$ with respect to variations of the $^{235}\text{U}$ and $^{239}\text{Pu}$ fluxes. On the other hand, the analysis of the rates of the short-baseline reactor neutrino experiments favor active-sterile neutrino oscillations and disfavor the suppression of the $^{235}\text{U}$ flux at $3.1σ$ and variations of the $^{235}\text{U}$ and $^{239}\text{Pu}$ fluxes at $2.8σ$. We also found that both the Daya Bay evolution data and the global rate data are well-fitted with composite hypotheses including variations of the $^{235}\text{U}$ or $^{239}\text{Pu}$ fluxes in addition to active-sterile neutrino oscillations. A combined analysis of the Daya Bay evolution data and the global rate data shows a slight preference for oscillations with respect to variations of the $^{235}\text{U}$ and $^{239}\text{Pu}$ fluxes. However, the best fits of the combined data are given by the composite models, with a preference for the model with an enhancement of the $^{239}\text{Pu}$ flux and relatively large oscillations.

description: The rapid rise of cryptocurrency has introduced both opportunities and challenges in the financial sector. While digital assets offer a decentralized and efficient means of conducting transactions, they have also become a preferred tool for criminals engaged in maritime illicit activities. From facilitating piracy ransom payments to funding smuggling rings, cryptocurrencies provide anonymity and global accessibility, making it difficult for regulators to track illicit financial flows. Offshore crypto exchanges further exacerbate the issue by offering unregulated financial services that can be exploited by criminal enterprises.

This paper argues that the unchecked use of cryptocurrencies in maritime financial crime threatens international security, economic stability, and the effectiveness of existing anti-money laundering (AML) frameworks. Without stringent regulations, these digital assets serve as an enabler for transnational crime, making it imperative for governments and financial institutions to take decisive action.
