Kit out to amp up -  The ARDC Trainer Toolkit
Creators: name: Wong, Adeline
Publisher: name: Zenodo
Year: 2023

description: Quality learning only happens when trainers are equipped with best practice andragogy and tools which guide the design and delivery of quality learning resources. Many in the digital research trainer community are subject matter experts (SMEs) or practitioners in their fields and are highly proficient at the tech they teach. But how might highly technical expert knowledge be translated for effective learning? How might training be made more accessible for diverse audiences? How might specialist trainers demonstrate their trainer value?

One way the Skilled Workforce Development team at the Australian Research Data Commons (ARDC) supports digital skills trainers is by kitting them out to help them upskill their learners and themselves.  The ARDC Trainer Toolkit comprises a suite of resources for trainers and their learners. These include the Trainer Certification Guide, learning resource self-assessment tools, and learning/training related templates. The self-assessment tools enable SMEs to critically reflect on their practices, encourage learner-centred approaches and apply inclusive design principles.

In helping trainers look out for diverse learners, there is also a need to look out for the trainer community and to help them make visible what's often invisible – their value. Certification often serves as shorthand for trainer skill sets and can help amplify trainer value.  A resource from the toolkit, the Trainer Certification Guide helps skills trainers in Australia navigate certification pathways.

This presentation aims to provide an overview of the ARDC Trainer Toolkit and showcase some of its tools. Feedback, and suggestions for new trainer resources is welcomed.
Do we need the $W^{(n>3)}$ constraints to solve the $(1,q)$ models coupled to 2D gravity?

description: We prove that all the correlation functions in the $(1,q)$ models are calculable using only the Virasoro and the $W^{(3)}$ constraints. This result is based on the invariance of correlators with respect to an interchange of the order of the operators they contain. In terms of the topological recursion relations, it means that only two and three contacts and the corresponding degenerations of the underlying surfaces are relevant. An algorithm to compute correlators for any $q$ and at any genus is presented and demonstrated through some examples. On route to these results, some interesting polynomial identities, which are generalizations of Abel's identity, were discovered. }

subject: Algebraic and differential geometry

description: The second fundamental form of Riemannian geometry is generalised to the case of a manifold with a linear connection and an integrable distribution. This bilinear form is generally not symmetric and its skew part is the torsion. The form itself is closely related to the shape map of the connection. The codimension one case generalises the traditional shape operator of Riemannian geometry.

The College has been a forerunner to venture semester system, comprehensive continuous evaluation, non-traditional methods of teaching & learning, inculcation of value system, personality development, career counseling and a fine tuned Tutor Guardian Cell (Mentor’s Club). Thanks to the Nutan fraternity and a galaxy of our graduates who transformed our tiny strides into a great success. It was even more reinforcing and rewarding to all of us when the state government decided to implement these initiatives at the state level.The preparation of SSR paved way to identify our short falls and we accepted it as an opportunity to work upon and transmute these into real strength. Over the years, the College has exercised the power of autonomy, to the extent allowed by the regulating body, to marginally update the curriculum. The students are permitted to view their valued answer books after declaration of results. ICT has been integrated in teaching, learning and the internet facility has been strengthened and supplemented with Wi-Fi. The academic departments have entered into collaboration and memorandum of understanding with other institutes. The faculty has been recognized and awarded at state and national level. The College has developed a plan for next one decade in the name of VISION 2025. Feedback from students on teachers has been restructured and from teachers on principal has been introduced for the first time.......... Interdisciplinary research work is being promoted, physical infrastructure has been augmented, teachers are using satellite communication for teaching, learning. Consultancy has been initiated and community linked extension activities are being given priority. The students have been given an opportunity for getting experience of real work situation through JOPW.But the quest for excellence is a process that never ends. The pursuit of quality enhancement must go on. We understand one cannot afford to sit upon one’s laurels. The present report is a humble submission of information pertaining to our College for assessment and accreditation. It is not a more plethora of achievements; rather, it is revelation of a path we have adhered to. Let us invite you to reel through the pages and be a part of our legacy. Dr H.K.

Models for Accretion Disk Fluctuations through Self-Organized Criticality Including Relativistic Effects

description: The possibility that some of the observed X-ray and optical variability in active galactic nuclei and galactic black hole candidates is produced in accretion disks through the development of a self-organized critical state is reconsidered. New simulations, including more complete calculations of relativistic effects, do show that this model can produce light-curves and power-spectra for the variability which agree with the range observed in optical and X-ray studies of AGN and X-ray binaries. However, the universality of complete self-organized criticality is not quite achieved. This is mainly because the character of the variations depend quite substantially on the extent of the unstable disk region. If it extends close to the innermost stable orbit then a physical scale is introduced and the scale-free character of self-organized criticality is vitiated. Significant dependence of the power spectrum density slope on the type of diffusion within the disk and a weaker dependence on the amount of differential rotation are noted. When general relativistic effects are incorporated in the models, additional substantial differences are produced if the disk is viewed from directions far from the accretion disk axis.

description: We derive curvature counterterms in two-dimensional gravity coupled to conformal matter up to infinite order. By construction the higher-order action is equivalent to a finite first-order theory with auxiliary scalar. Due to this equivalence it shares the following remarkable properties: There is no need for gravitational dressing of the cosmological constant, quantization is consistent for any conformal anomaly $c$ of the coupled matter system, and if the coupled matter system is a $c=d~$-dimensional string theory in a Euclidean background then the effective string theory is $D=d+2~$-dimensional with Minkowski signature $(1,D-1)$. The resulting quantum theory favours flat geometries and suppresses both parabolic and hyperbolic singularities.

description: Background: The metabolism of cancer cells is often reprogrammed by dysregulation of metabolic enzymes. Transketolase-like 1 (TKTL1) is a homodimeric transketolase linking the pentose-phosphate pathway with the glycolytic pathway. It is generally silenced at a transcriptional level in somatic tissues. However, in human cancers its expression is associated with the acquisition of a glycolytic phenotype (the Warburg effect) by cancer cells that contributes to the progression of malignant tumors. In melanoma, defective promoter methylation results in the expression of genes and their products that can affect the tumor cell's phenotype including the modification of immune and functional characteristics. The present study evaluates the role of TKTL1 as a mediator of disease progression in melanoma associated with a defective methylation phenotype. Methods: The expression of TKTL1 in metastatic melanoma tumors and cell lines was analysed by qRT-PCR and immunohistochemistry. The promoter methylation status of TKTL1 in melanoma cells was evaluated by quantitative methylation specific PCR. Using qRT-PCR, the effect of a DNA demethylating agent 5-aza-2'-deoxycytidine (5aza) on the expression of TKTL1 was examined. Biochemical and molecular analyses such as glucose consumption, lactate production, invasion, proliferation and cell cycle progression together with ectopic expression and siRNA mediated knockdown were used to investigate the role of TKTL1 in melanoma cells. Results: Expression of TKTL1 was highly restricted in normal adult tissues and was overexpressed in a subset of metastatic melanoma tumors and derived cell lines. The TKTL1 promoter was activated by hypomethylation and treatment with 5aza induced TKTL1 expression in melanoma cells. Augmented expression of TKTL1 in melanoma cells was associated with a glycolytic phenotype. Loss and gain of function studies revealed that TKTL1 contributed to enhanced invasion of melanoma cells. Conclusions: Our data provide evidence for an important role of TKTL1 in aerobic glycolysis and tumor promotion in melanoma that may result from defective promoter methylation. This epigenetic change may enable the natural selection of tumor cells with a metabolic phenotype and thereby provide a potential therapeutic target for a subset of melanoma tumors with elevated TKTL1 expression.

description: Spin wave dispersion in the metallic antiferromagnet Mn$_3$Pt was investigated just above the order-order transition temperature by using the inelastic neutron scattering technique. The spin wave dispersion at $T = 400$ K along [100], [110] and [111] directions was isotropic within the measurement accuracy. The dispersion was described by $({\hbarω})^2 = c^2q^2 + Δ^2$ with $c = 190$ meV Å and $Δ= 3.3$ meV. Compared with the dispersion at $T = 419$ K previously reported, the result demonstrates a large reduction of the stiffness constant $c$ with increasing temperature. This is similar to that observed in the metallic antiferromagnet FePt$_3$, and is an indication of the itinerancy of the magnetic moments.

description: The standard approach for integrating the multidimensional Vlasov equation using grid based, conservative schemes is based on a time splitting approach. Here, we show that although the truncation error is of second order, time splitting can introduce systematic heating of the plasma. We introduce a backsubstitution method, which not only avoids this deficiency but also is computationally less expensive. The general approach is demonstrated in conjunction with Boris' scheme for evaluating the characteristics.

Building a Collaborative Foundation for Australian Urban Digital Twins: Enhancing Interoperability as the First Step
Creators: name: Rahimi, Masoud
Publisher: name: Zenodo
Year: 2023
Subjects: Urban Digital Twins; Data Interoperability; Tools Interoperability

description: Urban Digital Twins (UDTs) offer effective enablers to addressing key Australian urban challenges, including climate change, energy transition and demographic transformation. UDTs' fit-for-purpose digital representations of the urban environment in 3- and 4-D, along with real-time data acquisition and analytical and modelling capabilities enable comprehending complex urban phenomena across time and space, allowing researchers, planners, and policymakers to create better-informed decisions.

However, effective implementation and application of UDTs in Australia are hindered by absence of standardised and coordinated approaches for accessing, exchanging, integrating, governing, and utilizing the wide range of available data and tools. This challenge results in time-consuming and costly processes, limiting the effective use and integration of UDTs. Moreover, complexity of customised workarounds hinders the seamless updating, adaptation, and governance of UDTs.

Collaboration is needed among Australian industries, academia, and governments to develop and evaluate standards, technologies, policies, and procedures. By assessing, designing and refining international best practices, we can promote interoperability in Australian UDTs holistically. This approach allows making knowledge assets findable, accessible, interoperable, and reusable, enabling effective utilization by both humans and machines, while maximizing the use of existing solutions.

This session will feature an interactive discussion among AURIN, OGC, CSIRO Data61, CSDILA, AGLDWG, FrontierSI and the audience. Lessons from national and international projects will be shared, emphasizing the significance of seamless interoperability for successful UDTs. We will discuss state-of-the-art technologies and standards for UDT implementation in open, secure, and scalable environments. This collaborative approach contributes to establishing a national consortium dedicated to advancing Australian UDTs.

description: We discuss different exotic phases and components of matter from the crust to the core of neutron stars based on theoretical models for equations of state relevant to core collapse supernova simulations and neutron star merger. Parameters of the models are constrained from laboratory experiments. It is observed that equations of state involving strangeness degrees of freedom such as hyperons and Bose-Einstein condensates are compatible with 2M$_{solar}$ neutron stars. The role of hyperons is explored on the evolution and stability of the protoneutron star (PNS) in the context of SN1987A. Moment of inertia, mass and radius which are direct probes of neutron star interior are computed and their observational consequences are discussed. We continue our study on the dense matter under strong magnetic fields and its application to magnetoelastic oscillations of neutron stars.

description: Beak and feather disease virus (BFDV) threatens a wide range of endangered psittacine birds worldwide. In this study, we assessed a novel PCR assay and genetic screening method using high-resolution melt (HRM) curve analysis for BFDV targeting the capsid (Cap) gene (HRM-Cap) alongside conventional PCR detection as well as a PCR method that targets a much smaller fragment of the virus genome in the replicase initiator protein (Rep) gene (HRM-Rep). Limits of detection, sensitivity, specificity and discriminatory power for differentiating BFDV sequences were compared. HRM-Cap had a high positive predictive value and could readily differentiate between a reference genotype and 17 other diverse BFDV genomes with more discriminatory power (genotype confidence percentage) than HRM-Rep. Melt curve profiles generated by HRM-Cap correlated with unique DNA sequence profiles for each individual test genome. The limit of detection of HRM-Cap was lower (2 × 10−5 ng/reaction or 48 viral copies) than that for both HRM-Rep and conventional BFDV PCR which had similar sensitivity (2 × 10−6 ng or 13 viral copies/reaction). However, when used in a diagnostic setting with 348 clinical samples there was strong agreement between HRM-Cap and conventional PCR (kappa = 0.87, P < 0.01, 98% specificity) and HRM-Cap demonstrated higher specificity (99.9%) than HRM-Rep (80.3%).

description: Alzheimer's disease (AD) is an irreversible brain disease that can dramatically reduce quality of life, most commonly manifesting in older adults and eventually leading to the need for full-time care. Early detection is fundamental to slowing its progression; however, diagnosis can be expensive, time-consuming, and invasive. In this work we develop a neural model based on a CNN-LSTM architecture that learns to detect AD and related dementias using targeted and implicitly-learned features from conversational transcripts. Our approach establishes the new state of the art on the DementiaBank dataset, achieving an F1 score of 0.929 when classifying participants into AD and control groups.

description: Accurate prediction of solar activity calls for precise calibration of solar cycle models. Consequently we aim to find optimal parameters for models which describe the physical processes on the solar surface, which in turn act as proxies for what occurs in the interior and provide source terms for coronal models. We use a genetic algorithm to optimize surface flux transport models using National Solar Observatory (NSO) magnetogram data for Solar Cycle 23. This is applied to both a 1D model that inserts new magnetic flux in the form of idealized bipolar magnetic regions, and also to a 2D model that assimilates specific shapes of real active regions. The genetic algorithm searches for parameter sets (meridional flow speed and profile, supergranular diffusivity, initial magnetic field, and radial decay time) that produce the best fit between observed and simulated butterfly diagrams, weighted by a latitude-dependent error structure which reflects uncertainty in observations. Due to the easily adaptable nature of the 2D model, the optimization process is repeated for Cycles 21, 22, and 24 in order to analyse cycle-to-cycle variation of the optimal solution. We find that the ranges and optimal solutions for the various regimes are in reasonable agreement with results from the literature, both theoretical and observational. The optimal meridional flow profiles for each regime are almost entirely within observational bounds determined by magnetic feature tracking, with the 2D model being able to accommodate the mean observed profile more successfully. Differences between models appear to be important in deciding values for the diffusive and decay terms. In like fashion, differences in the behaviours of different solar cycles lead to contrasts in parameters defining the meridional flow and initial field strength.

description: Given a spacetime with nonvanishing torsion, we discuss the equation for the evolution of the separation vector between infinitesimally close curves in a congruence. We show that the presence of a torsion field leads, in general, to tangent and orthogonal effects on the congruence; in particular, the presence of a completely generic torsion field contributes to a relative acceleration between test particles. We derive, for the first time in the literature, the Raychaudhuri equation for a congruence of timelike and null curves in a spacetime with the most generic torsion field.

Subjects: Public cloud; Collaborative open infrastructure; Biodiversity

description: The Atlas of Living Australia (ALA) is a collaborative open infrastructure that pulls together Australian biodiversity data from multiple sources, making it accessible and reusable for scientists, policymakers, government, industry and the general public.

The ALA has embraced the potential of cloud computing since 2014, using cloud infrastructure provided by NCI and Nectar, and Amazon Web Services (AWS) as their public cloud provider, allowing the ALA to combine storage, compute, database and serverless services into their solutions.

In 2022, the ALA started a program to improve its user experience and security posture. It began by upgrading core applications to leverage the OpenID protocol for seamless authentication and authorisation across ALA portals and applications with a single set of credentials and OpenID Connect, built on OAuth 2.0, to guarantee secure and standardised integration.

By leveraging public cloud services such as Amazon API Gateway and Amazon Cognito, the ALA added scalability, multi-factor authentication (MFA), audit, encryption, and compromised credential detection, among others, ensuring robust security and privacy, and federation with identity providers like Australian Access Federation and social login (e.g., Facebook, Google).

The ALA now supports machine-to-machine interactions, single-page applications (SPA), native mobile apps, and API access. It provides researchers and stakeholders access to over 114 million species occurrence records, comprehensive taxonomy for more than 153,000 species, and over 150 web services for data accessibility and functionality. By leveraging secure and scalable cloud solutions, the ALA delivers its mission of enabling open, accessible, and reusable data to support world-class research and decision-making.

description: The dependence of random telegraph noise (RTN) amplitude on the gate overdrive in a junctionless field-effect transistor (FinFET) with rectangular and trapezoidal channel (fin) cross sections manufactured using silicon-on-insulator technology has been numerically simulated. It is established that the RTN amplitude in the subthreshold region of gate voltages for a FinFET with a trapezoidal cross-section of the channel is significantly lower than that for the transistor with a rectangular cross-section of a channel. In addition, under the same conditions, the RTN amplitude at the threshold gate voltage in a junctionless FinFET is significantly lower than that in planar fully depleted and in usual FinFET.

description: Recent experimental results from the Trident laser confirm the importance of kinetic effects in determining laser reflectivities at high intensities. Examples observed include scattering from low frequency electron acoustic waves (EAWs), and the first few stages of a cascade towards turbulence through the Langmuir decay instability. Interpretive and predictive computational capability in this area is assisted by the development of Vlasov codes, which offer high velocity space resolution in high energy regions of particle phase space, and do not require analytical pre-processing of the fundamental equations. A direct Vlasov solver, capable of resolving these kinetic processes, is used here to address fundamental aspects of the existence and stability of the electron acoustic wave, together with its collective scattering properties. These simulations are extended to realistic laser and plasma parameters characteristic of single hot-spot experiments. Results are in qualitative agreement with experiments displaying both stimulated Raman and stimulated electron acoustic scattering. The amplitude of simulated EAWs is greater than that observed experimentally, and is accompanied by a higher phase velocity. These minor differences can be attributed to the limitations of a one-dimensional collisionless model.

description: The proposed study investigates the damage mechanisms of martensitic stainless steel X3CrNiMo13-4 exposed to cavitation using two complementary experimental apparatus: ultrasonic horn (MUCEF) and hydrodynamic tunnel (PREVERO). Cavitation testing has been carried out on two different metallurgical states: QT780 and QT900 corresponding to coarse and fine microstructure respectively. Acoustic cavitation erosion tests have been performed on the MUCEF equipment inspired from the ASTM G32 standards but specially designed to be installed inside X-Ray tomographs. The ultrasonic horn operates at 20 kHz and the tested specimen is located at 500 $μ$m from the horn tip. Hydrodynamic cavitation erosion tests were conducted with classic experimental conditions of PREVERO device: a cavitation number of 0.87 corresponding to a flow velocity of 90 m.s-1 and an upstream pressure of 40 bars. For acoustic cavitation, mass loss has been identified as dependent of the microstructure while for hydrodynamic cavitation the mass loss is identical whatever the microstructure size.

description: We investigate current-voltage (I-V) characteristics of the ferroelectric material colemanite at room temperature, at a high temperature, and also under the influence of near ultraviolet light. We demonstrate that all three I-V plots exhibit hysteresis effects, and these new results shed new light on the resistance of colemanite. These novel properties are explained on the basis of its microstructure indicating potential applications in devices with negative resistance as well as in photovoltaic devices.

description: In NaNiO2, Ni3+ ions form a quasi two dimensional triangular lattice of S = 1=2 spins. The magnetic order observed below 20K has been described as an A type antiferromagnet with ferro- magnetic layers weakly coupled antiferromagnetically. We studied the magnetic excitations with the electron spin resonance for frequencies 1-20 cm-1, in magnetic fields up to 14 T. The bulk of the results are interpreted in terms of a phenomenological model involving bi-axial anisotropy for the spins: a strong easy-plane term, and a weaker anisotropy within the plane. The direction of the easy plane is constrained by the collective Jahn-Teller distortion occurring in this material at 480 K.
'Don't ruin it with mandatory questions. Mandatory questions aren't cool.': Building a popular research data manager

description: One challenging barrier to the introduction of a new system is user adoption. Researchers are resistant to change in areas where there is already a 'workable' solution in place. However, external hard drives and local share drives do not meet the standards of a good data management plan, let alone best practice in research data management. The goal at UQ was to gain majority user adoption of UQ Research Data Manager (UQRDM) to securely store and manage the university's valuable research data.

The approach used by the UQRDM team to go from launch to 20,000 unique active users in 5 years was simple – provide data storage designed to meet the needs and requirements of researchers. UQRDM data storage is centralized and accessible by mapped drive and cloud interface providing 1 TB of free storage. Storage allocations are project based and can be shared with all collaborators and industry partners. The only requirement for access to UQRDM is a project title and the names of the researchers accessing the data.

Simple design for researchers doesn't mean easy for the UQRDM, Data Library, or ITS teams. A joint effort was undertaken, to promote UQRDM among researchers and administration, gain user adoption, support the system, and deliver continuous improvement. This presentation will describe how these teams successfully accomplished this task, making UQRDM one the largest and most used research data manager in Australia, having provisioned 13,000 researchers and 10,000 students 120 PB of data for more than 18,000 project records.

description: The search for a theory of quantum gravity is the most fundamental problem in all of theoretical physics, but there are as yet no experimental results at all to guide this endeavor. What seems to be needed is a pragmatic way to test if gravitation really occurs between quantum objects or not. In this article we suggest such a potential way out of this deadlock, utilizing macroscopic quantum systems; superfluid helium, gaseous Bose-Einstein condensates and "macroscopic" molecules. It turns out that true quantum gravity effects - here defined as observable gravitational interactions between truly quantum objects - could and should be seen (if they occur in nature) using existing technology. A falsification of the low-energy limit, in the accessible weak-field regime, would also falsify the full theory of quantum gravity, making it enter the realm of testable, potentially falsifiable theories, i.e. becoming real physics after almost a century of pure theorizing. If weak-field gravity between quantum objects is shown to be absent (in the regime where the approximation should apply), we know that gravity then is a strictly classical phenomenon absent at the quantum level.

description: By adiabatically manipulating tunneling amplitudes of cold atoms in a periodic potential with a multiple sublattice structure, we are able to coherently transfer atoms from a sublattice to another without populating the intermediate sublattice, which can be regarded as a spatial analogue of stimulated Raman adiabatic passage. A key is the existence of dark eigenstates forming a flat band in a Lieb-type optical lattice. We also successfully observe a matter-wave analogue of Autler-Townes doublet using the same setup. This work shed light on a novel kind of coherent control of cold atoms in optical potentials.

description: Pervasive Computing is a very challenging and complex domain that still lacks a comprehensive unified architecture. In this paper, we propose a reference architecture for pervasive computing that captures most, if not all, of the key challenges and provides a new architecture model that can be used in almost any business context. It provides conceptual views for the smart environment (SE), the smart object (SO), and the pervasive system (PS). We evaluated the model using a simulation prototype to predict its reliability at runtime.

description: As pointed out in previous studies, the measurement of the skewness of the convergence field $κ$ will be useful in breaking the degeneracy among the cosmological parameters constrained from weak lensing observations. The combination of shot noise and finite survey volume implies that such a measurement is likely to be done in a range of intermediate scales ($0.5'$ to 20') where neither perturbation theory nor the hierarchical ansatz apply. Here we explore the behavior of the skewness of $κ$ at these intermediate scales, based on results for the non-linear evolution of the mass bispectrum. We combined different ray-tracing simulations to test our predictions, and we find that our calculations describe accurately the transition from the weakly non-linear to the strongly non-linear regime. We show that the single lens-plane approximation remains accurate even in the non-linear regime, and we explicitly calculate the corrections to this approximation. We also discuss the prospects of measuring the skewness in upcoming weak lensing surveys.

description: Distance measurements beyond geometrical and semi-geometrical methods, rely mainly on standard candles. As the name suggests, these objects have known luminosities by virtue of their intrinsic proprieties and play a major role in our understanding of modern cosmology. The main caveats associated with standard candles are their absolute calibration, contamination of the sample from other sources and systematic uncertainties. The absolute calibration mainly depends on their chemical composition and age. To understand the impact of these effects on the distance scale, it is essential to develop methods based on different sample of standard candles. Here we review the fundamental properties of young and intermediate-age distance indicators such as Cepheids, Mira variables and Red Clump stars and the recent developments in their application as distance indicators.
