description: We consider the even parity superLax operator for the supersymmetric KP hierarchy of the form $L~=~D^2 + \sum_{i=0}^\infty u_{i-2} D^{-i+1}$ and obtain the two Hamiltonian structures following the standard method of Gelfand and Dikii. We observe that the first Hamiltonian structure is local and linear whereas the second Hamiltonian structure is non-local and nonlinear among the superfields appearing in the Lax operator. We discuss briefly on their connections with the super $w_{\infty}$ algebra.

description: Conditional local independence is an asymmetric independence relation among continuous time stochastic processes. It describes whether the evolution of one process is directly influenced by another process given the histories of additional processes, and it is important for the description and learning of causal relations among processes. We develop a model-free framework for testing the hypothesis that a counting process is conditionally locally independent of another process. To this end, we introduce a new functional parameter called the Local Covariance Measure (LCM), which quantifies deviations from the hypothesis. Following the principles of double machine learning, we propose an estimator of the LCM and a test of the hypothesis using nonparametric estimators and sample splitting or cross-fitting. We call this test the (cross-fitted) Local Covariance Test ((X)-LCT), and we show that its level and power can be controlled uniformly, provided that the nonparametric estimators are consistent with modest rates. We illustrate the theory by an example based on a marginalized Cox model with time-dependent covariates, and we show in simulations that when double machine learning is used in combination with cross-fitting, then the test works well without restrictive parametric assumptions.

Building EcoCommons Australia - the Good, the Bad and the Ugly
Creators: name: Bayraktarov, Elisa
Publisher: name: Zenodo
Year: 2023

description: EcoCommons Australia, a partnership of nine organisations (including ARDC, QCIF and Griffith University), aims to provide ecological and environmental researchers and policymakers with access to trusted, world-leading modelling tools, environmental data and a flexible national digital research infrastructure. With a total investment of approximately $8.45M since 2013, EcoCommons has evolved from its predecessors (Biodiversity and Climate Change Virtual Laboratory, ecocloud and the Collaborative Species Distribution Modelling Portal) to become the platform of choice for ecological and environment modelling.

Launched in November 2022, EcoCommons has now attracted over 600 registered users from universities, government agencies, and environmental NGOs, gaining recognition through multiple prestigious awards. However, behind the success lies a story of challenges and lessons learned in building a platform of this magnitude in a post-COVID world.

In this presentation, I will explore the "Good, the Bad, and the Ugly" aspects of EcoCommons, sharing experiences and insights gained throughout its development. Key challenges encompassed staff availability, skills, and training, while ensuring staff wellbeing and work/life balance. Managing multiple collaborations and handling Technical Debt accumulation posed additional hurdles. Moreover, staying abreast of ever-evolving science and technology and ensuring sustainability proved to be continuous struggles.

This talk aims to summarise the valuable lessons learned from developing a complex digital innovation platform. By sharing our experiences, I hope to provide valuable advice to those involved in building National Research Infrastructure.

description: Nuclear reactions induced by muon neutrino with energies in the range from 0.2 to 1.5 GeV in Monte Carlo calculations framework in the intra-nuclear cascade model are studied. This study was done by comparison between the available experimental data and theoretical values of total cross section, and the energy distribution of emitted lepton energy in the reaction muon neutrino-nucleus, using the targets: $^{12}$C, $^{16}$O, $^{27}$Al, $^{40}$Ar, $^{56}$Fe and $^{208}$Pb. A phenomenological toy model of primary neutrino-nucleon interaction gives a good agreement of our theoretical inclusive neutrino nucleus cross in comparison with the available experimental data. Some interesting results on the behavior of the cross section as function of 1p-1n and higher contributions are also sketched. The previous results on the percentage of fake events related in available experiments in $^{12}$C were expanded for the set studied nuclei. With the increase of mass target, the nuclear effects in the cross sections were observed along with the importance to take into account fake events in the reactions.

description: We outline a theoretical approach supporting strong phase transitions from normal nuclear matter to the deconfined quark-gluon plasma, in the equation of state (EOS) for compact star matter. Implications of this hypothesis are discussed for astrophysical applications. Special emphasis is devoted to potentially detectable signatures, which can be directly related with the occurrence of a sufficiently strong phase transition. Therefore, simulations of core-collapse supernovae and binary compact star mergers are considered, including the subsequent emission of gravitational waves and, in the case of supernova, in addition the neutrinos play the role of messengers.

Laboratory Practices for Purification of Drinking Water

subject: FOS: Biological sciences

description: Cyanophytes encompass an old subdivision of minuscule organisms, settled in a large variety of environments such as freshwaters, sea, oceans, rocks, soil and hot springs. In freshwaters, some are benthic, but many are found on the surface, floating at the mercy of winds and water currents. Under enriched conditions, these unicellular microscopic entities multiply profusely, amassed together and form scums. On lysis, they produce toxins that are not easily inactivated by laboratory equivalents of water purification process viz. flocculation-filtration-chlorination treatment. Even activated carbon, in small doses, falls short to yield desirable results. However, vast amount of charcoal can do so. Besides, activated carbon filtration, in combination with ionization, has been found effectual in neutralizing toxins.As a rule, slow sand-filters are considered to be more dependable than high-speed filters in doing away with phytoplankton. Albeit, the slow filters do not take out color from water as some cyanophytes succeed in penetrating the filtration bed. Moreover, Microcystis aeruginosa, at the ultimate stages of bloom formation secretes substantial amount of organic compounds with polysaccharide base. This dross is seldom removed by conventional treatments like sand-filtration, Al2(SO4)3 coagulation, FeCl3 flocculation, sedimentation, etc. and much of it goes into the water supply, making the water obnoxious to users. Though toxic degradations are possible, yet the current state of practice seems insufficient to exterminate cent-per-cent algae from raw water entering the supply system.Although there is no way to deal with these nuisance microphytes, use of blue stone CuSO4 in chunk or granular form can be suggested as an algicide. However, the same cannot be used further than a certain limit and that too in a large basin. Obviously, ionization at the end of filtration may be a good permutation to get rid of plant organisms with their associated organoleptic properties.

description: We consider the quantum stochastic dynamics of a system whose interaction with the reservoir is considered to be linear in bath co-ordinates but nonlinear in system co-ordinates. The role of the space-dependent friction and diffusion has been examined in the decay rate of a particle from a meta-stable well. We show how the decay rate can be hindered by inhomogeneous dissipation due nonlinear system-bath coupling strength.

description: (abridged) We investigate the signatures left by the cosmic neutrino background on the clustering of matter, CDM+baryons and halos in redshift-space using a set of more than 1000 N-body and hydrodynamical simulations with massless and massive neutrinos. We find that the effect neutrinos induce on the clustering of CDM+baryons in redshift-space on small scales is almost entirely due to the change in $σ_8$. Neutrinos imprint a characteristic signature in the quadrupole of the matter (CDM+baryons+neutrinos) field on small scales, that can be used to disentangle the effect of $σ_8$ and $M_ν$. We show that the effect of neutrinos on the clustering of halos is very different, on all scales, to the one induced by $σ_8$. We find that the effects of neutrinos of the growth rate of CDM+baryons ranges from $\sim0.3\%$ to $2\%$ on scales $k\in[0.01, 0.5]~h{\rm Mpc}^{-1}$ for neutrinos with masses $M_ν\leqslant 0.15$ eV. We compute the bias between the momentum of halos and the momentum of CDM+baryon and find it to be 1 on large scales for all models with massless and massive neutrinos considered. This point towards a velocity bias between halos and total matter on large scales that it is important to account for in order to extract unbiased neutrino information from velocity/momentum surveys such as kSZ observations. We show that baryonic effects can affect the clustering of matter and CDM+baryons in redshift-space by up to a few percent down to $k=0.5~h{\rm Mpc}^{-1}$. We find that hydrodynamics and astrophysical processes, as implemented in our simulations, only distort the relative effect that neutrinos induce on the anisotropic clustering of matter, CDM+baryons and halos in redshift-space by less than $1\%$. Thus, the effect of neutrinos in the fully non-linear regime can be written as a transfer function with very weak dependence on astrophysics.

Approximate Implicitization of Triangular Bézier Surfaces

description: We discuss how Dokken's methods of approximate implicitization can be applied to triangular Bézier surfaces in both the original and weak forms. The matrices $\mathbf{D}$ and $\mathbf{M}$ that are fundamental to the respective forms of approximate implicitization are shown to be constructed essentially by repeated multiplication of polynomials and by matrix multiplication. A numerical approach to weak approximate implicitization is also considered and we show that symmetries within this algorithm can be exploited to reduce the computation time of $\mathbf{M}.$ Explicit examples are presented to compare the methods and to demonstrate properties of the approximations.

description: Recently, the free energy of the target space mean field (TSMF) matrix model has been calculated in the low temperature phase, order-by-order in a low temperature expansion. The TSMF model is a matrix model whose discrete target space has an infinite coordination number, and whose free energy assumes a universal form, corresponding to baby universes joined into a tree. Here the free energy is summed to all orders, and expressed through a transcendental algebraic equation, using which we analyze the critical phenomena that occur in the TSMF model. There are two critical curves, at which the matter and the geometry become critical, and for which the critical exponents are alpha = 1/2 and gamma_str = -1/2, respectively. There is a bicritical point where the curves meet, at which gamma_str = +1/3.

description: Cluster algebras have recently become an important player in mathematics and physics. In this work, we investigate them through the lens of modern data science, specifically with techniques from network science and machine learning. Network analysis methods are applied to the exchange graphs for cluster algebras of varying mutation types. The analysis indicates that when the graphs are represented without identifying by permutation equivalence between clusters an elegant symmetry emerges in the quiver exchange graph embedding. The ratio between number of seeds and number of quivers associated to this symmetry is computed for finite Dynkin type algebras up to rank 5, and conjectured for higher ranks. Simple machine learning techniques successfully learn to classify cluster algebras using the data of seeds. The learning performance exceeds 0.9 accuracies between algebras of the same mutation type and between types, as well as relative to artificially generated data.

Building Bunya: An Evergreen and Bespoke Approach to High-Performance Computing Clusters
Creators: name: Walters, Sarah
Publisher: name: Zenodo
Year: 2023

description: High-Performance Computing (HPC) clusters are complex systems comprising various hardware and software components. Typically, these systems are acquired through a single large purchase and implemented using pre-configured software packages like OpenHPC. However, this conventional approach hampers individual component upgrades and presents budgetary challenges due to substantial upfront costs.

At the University of Queensland (UQ) Research Computing Centre (RCC), we have embraced an evergreen approach to HPC clusters. Our bespoke cluster, Bunya, leverages commodity components, allowing incremental additions of diverse system configurations over time. Along with a regular funding cycle of smaller annual investments, research groups are encouraged to contribute by purchasing additional hardware, which seamlessly integrates into Bunya. This collaborative model ensures a constant influx of cutting-edge technologies, including upcoming GPUs, empowering researchers to leverage the latest architectures.

To address researchers' evolving needs, we employ modern configuration management techniques and leverage EasyBuild for streamlined software deployment. These practices are complemented by rigorous testing suites that evaluate software before deployment. This enables us to respond rapidly to changing requirements, encourage end-user contributions to package builds, and accommodate a wide range of hardware and software configurations on the Bunya HPC cluster.

In our presentation, we will delve into the advantages of our bespoke design, highlighting the flexibility, control, and adaptability it offers. Additionally, we will discuss the software stack we employ to support the cluster.

Through our approach, we have accelerated the deployment of new hardware and software, providing timely solutions to meet the ever-evolving requirements of our researchers.

description: There is growing scientific consensus that an average global warming of 2°C above the pre-industrial level, which is around 450 ppm atmospheric carbon dioxide equivalent (IPCC 4th Assessment Working Group I), would constitute a dangerous level of climate change with serious implications for the achievement of Millennium Development Goals, the objectives of the Convention on Biological Diversity (CBD) and other Rio Conventions.Global greenhouse gas emissions are on an accelerating trend and if left unchecked, could lead to a 6.4°C (11.5° F) temperature increase by the end of the century, exceeding conservative estimates (The Copenhagen Diagnosis: Climate Science Report).It is now widely recognized that climate change and biodiversity are interconnected, not only through the effects of climate change on biodiversity, but also through changes in biodiversity and ecosystem functioning that affect climate change. The carbon cycle and the water cycle, arguably the two most important large scale processes for life on Earth, both depend on biodiversity at genetic, species and ecosystem levels.The Millennium Ecosystem Assessment identified climate change as a dominant driver of future biodiversity loss and indicated that it would adversely affect key development challenges, including the provision of clean water, energy services, & food; maintenance of a healthy environment; and conservation of ecological systems, their biodiversity, and associated ecosystem goods and services (Ecosystems & Human Well-being : Policy Responses).

description: Polar topological structures in ferroelectric thin films have recently drawn significant interest due to their fascinating physical behaviors and promising applications in high-density nonvolatile memories. However, most polar topological patterns are only observed in the perovskites superlattices. Here, we report the discovery of the tunable ferroelectric polar topological defective structures designed and achieved by strain engineering in two-dimensional PbX (X=S, Se, and Te) materials using multiscale computational simulations. First, the first-principles calculations demonstrate the strain-induced recoverable ferroelectric phase transition in such 2D materials. The unique polar topological vortex pattern is then induced by applied mechanical indentation, evidenced by molecular dynamics simulations based on a developed deep-learning potential. According to the strain phase diagram and applied complex strain loadings, the diverse polar topological structures, including antivortex structure and flux-closure structure, are predicted to be emergent through the finite-element simulations. We conclude that strain engineering is promising to tailor various designed reversible polar topologies in ultra-flexible 2D materials, which provide excellent opportunities for next-generation nanoelectronics and sensor devices.

Mass estimates in short-period compact binaries

description: Using stellar models we investigate the relation between mass and the spectral type of the secondary star in low-mass short-period compact binaries such as cataclysmic variables and soft X-ray transients. Allowing for different mass transfer rates and different system ages prior to mass transfer we find that the secondaries should populate a band in the spectral type vs. mass plane. The mass M_ms of a ZAMS star with the same spectral type as the donor is effectively an upper limit to the donor mass. The lower mass limit for a given spectral type depends on the mixing length parameter. If this is large, there is no lower limit if the spectral type is later than K6. The band width decreases from 0.4 M_sun at K6 to less than 0.2 M_sun at K0. If the mixing length parameter is small, there is no lower mass limit if the spectral type is later than M2, and the band width decreases from 0.2 M_sun at M2 to less than 0.1 M_sun for types earlier than K0. We also point out an error in the method suggested by Beekman et al. (1997) to estimate the primary mass in a soft X-ray transient.

description: We consider the statistics of the areas enclosed by domain boundaries (`hulls') during the curvature-driven coarsening dynamics of a two-dimensional nonconserved scalar field from a disordered initial state. We show that the number of hulls per unit area that enclose an area greater than $A$ has, for large time $t$, the scaling form $N_h(A,t) = 2c/(A+λt)$, demonstrating the validity of dynamical scaling in this system, where $c=1/8π\sqrt{3}$ is a universal constant. Domain areas (regions of aligned spins) have a similar distribution up to very large values of $A/λt$. Identical forms are obtained for coarsening from a critical initial state, but with $c$ replaced by $c/2$.

description: Microcosmal studies were carried out on three inland reservoirs – Upper lake, Lower lake and Shahpura lake, Bhopal, by housing definite amount of water and soil aliquota from natural waters. Changes in physicochemical and limnobiological parameters were recorded at an interval of 1, 3, 5, 10, 15 and 30 days.Exposure to nutrients not only checked the development of Chlorophyceae during colonization but also initiated major shifts in the sociology of phytoplankton after a short time. Supply of nutrients upto 5 mg/l concentration did not affect the vegetation significantly, however, further enrichment largely supressed the ground water dominants i.e, Chlorophytes. Conditions, similar to controlled ones, prevailed in treated microcosms too, but for those treated with 10 mg/l and 15 mg/l of nutrients where blue-green forms dominated at the cost of prevailing green algae. In all cases, Crucigenia crucifera, C. rectangularis, Scenedesmus abundans (UL & LL), S. bijugatus, S. dimorphus (UL, LL & SL), Characiopsis longipes, Crucigenia quadricauda and Scenedesmus armatus (SL) registered their presence for most of the period whereas, certain strains viz. Ankistrodesmus falcatus, Scenedesmus obliques, S. parisiensis, S. quadricauda, Amphora ovalis (UL), Eudorina elegans, Oocystis crassa, Staurastrum gracile, S. orbicularae, Tetraedron minimum, Cosmarium granatum (LL), Coelastrum microporum, Pediastrum tetras and Selanastrum gracile (SL) could not withstand the nutritional changes and perished earlier.Both calcium and magnesium acetate evinced no drastic effect on diatom community, however, depletion in nutrients rendered a regular decline in number with respect to duration. Further, Melosira granulata, which was abundant in natural lakes, propogated successfully in enriched waters and expressed itself to be a eutrophic form. Other species, which indicated a positive correlation with magnesium, include Fragillaria, Navicula cryptocephala, Nitzchia closterium & Tabellaria sps. in Upper lake and Cymbella affinis & Synedra ulna in Lower lake microcosms.Among Cyanophytes, initial growth mainly consisted of Arthrospira massartis (UL & SL), Anabaena sps, Merismopedia punctata (LL & SL), Nostoc microscopicum and Oscillatoria amphigranulata as in natural waters but after addition of nutrient there occurred a sudden spread of Microcystis aeruginosa. It was, atleast in part, due to changed competitive situation where Microcystis sps succeeded in surpassing other forms.Dinophytes underwent swift decline and finally succumbed within a fortnight.

description: We present here numerical modelling of granular flows with the $μ(I)$ rheology in confined channels. The contribution is twofold: (i) a model to approximate the Navier-Stokes equations with the $μ(I)$ rheology through an asymptotic analysis. Under the hypothesis of a one-dimensional flow, this model takes into account side walls friction; (ii) a multilayer discretization following Fernández-Nieto et al. (J. Fluid Mech., vol. 798, 2016, pp. 643-681). In this new numerical scheme, we propose an appropriate treatment of the rheological terms through a hydrostatic reconstruction which allows this scheme to be well-balanced and therefore to deal with dry areas. Based on academic tests, we first evaluate the influence of the width of the channel on the normal profiles of the downslope velocity thanks to the multilayer approach that is intrinsically able to describe changes from Bagnold to S-shaped (and vice versa) velocity profiles. We also check the well balance property of the proposed numerical scheme. We show that approximating side walls friction using single-layer models may lead to strong errors. Secondly, we compare the numerical results with experimental data on granular collapses. We show that the proposed scheme allows us to qualitatively reproduce the deposit in the case of a rigid bed (i. e. dry area) and that the error made by replacing the dry area by a small layer of material may be large if this layer is not thin enough. The proposed model is also able to reproduce the time evolution of the free surface and of the flow/no-flow interface. In addition, it reproduces the effect of erosion for granular flows over initially static material lying on the bed. This is possible when using a variable friction coefficient $μ(I)$ but not with a constant friction coefficient.

description: Background: Starting a study programme at an university, students are confronted with rising requirements regulating their learning processes and motivation. Both difficulties due to this regulation and the quality of instruction are associated with students dropping out from a study programme in the research. Aims: The purpose of this research is to analyse the interplay and effect of difficulties in self-regulated learning, achievement motivation (i.e. academic self-concept, subject interest), and perceived quality of instruction in dropping out from an university study programme. Sample: We sampled 2301 cooperative students in their first academic year. The average age was M = 22.12 (SD = 3.02), and 1167 were male (50.7%). Method: This cross-sectional study used structural equation models for hypothesis analysis. Three years after the survey, dropout information from the university administration was matched to the survey data. Results: The results indicate associations between academic self-concept, subject interest and difficulties in regulating one's motivation with dropout. An indirect effect was found between perceived quality of instruction and dropout via academic self-concept, subject interest and difficulties in regulating one's motivation. Conclusions: The relevance of perceived quality of instruction, self-concept, subject interest and difficulties in motivational regulation and consequences for dropout is illustrated.

Subjects: Persistent Identifiers

description: The Australian Persistent Identifier (PID) graph (also known as National PID Graph) connects Australian research to funders, research activities, and research outcomes using persistent identifiers. Connections between ORCID, ROR, DOI, RAID, and other PIDs provide a valuable source of information about the digital footprint of research and the collaboration network of Australian researchers. In this presentation, we offer insights about the key nodes in this network, such as the most connected funded projects in Australia, and the researchers who have the most international collaborations. We demonstrate how well-established graph algorithms, such as centrality, can offer insights about Australian research, revealing hub nodes and bridge nodes that provide critical links between communities. Additionally, we report on the state of the missing links in the Australian PID graph, including missing ORCID links from publications and ARC/NHMRC grants, as well as missing ROR records for Australian organisations that are collaborators in this network.

description: In this work, we study the entropies of photons, dust (baryonic matter), dark matter, and dark energy in the context of cosmology. When these components expand freely with the universe, we calculate the entropy and specific entropy of each component from the perspective of statistics. Under specific assumptions and conditions, the entropies of these components can satisfy the second law of thermodynamics independently. Our calculations show that the specific entropy of matter cannot be a constant during the expansion of the universe except for photons. When these components interact with the space-time background, there could exist the phenomenon of particle production (annihilation). We study the influence of the interaction on the entropies of these components, and obtain the conditions guaranteeing that the entropy of each component satisfies the second law of thermodynamics.

description: Motivated by the close analogy with the fractional quantum Hall states (FQHSs), fractional Chern insulators (FCIs) are envisioned as strongly correlated, incompressible states emerging in a fractionally filled, (nearly) flat band with non-trivial Chern number. Built upon this vision, fractional topological insulators (FTIs) have been proposed as being composed of two independent copies of the FCI with opposite Chern numbers for different spins, preserving the time-reversal symmetry as a whole. An important question is if the correlation between electrons with different spins can be really ignored. To address this question, we investigate the effects of correlation in the presence of spin-dependent holomorphicity, i.e., electrons of one spin species reside in the holomorphic lowest Landau level, while those of the other in the antiholomorphic counterpart. By constructing and performing exact diagonalization of an appropriate model Hamiltonian, here, we show that generic, strongly correlated, fractionally filled states with spin-dependent holomorphicity cannot be described as two independent copies of the FQHS, suggesting that FTIs in the lattice cannot be described as those of the FCI either. Fractionally filled states in this system are generally compressible except at half filling, where an insulating state called the half-filled spin-holomorphic FTI occurs. It is predicted that the half-filled spin-holomorphic FTI is susceptible to an inherent spontaneous symmetry breaking, leading to the spatial separation of spins.

description: We present the first experimental confirmation of the so-called "self-phaselocked delay interferometry". This laser frequency stabilization technique consists basically in comparing the prompt laser signal with a delayed version of itself that has been reflected in another LISA satellite 5 million km away. In our table-top experiment, the phase of a voltage-controlled oscillator is stabilized by means of a control loop based on this technique. In agreement with the theory, the measured unity gain frequency is not limited by the inverse of the used delay (1.6 microseconds). In the time domain, the system also behaves as predicted, including the appearance of a quasi-periodic "ringing" just after the lock acquisition, which decays exponentially. Its initial amplitude is smaller when the loop gain is slowly ramped up instead of suddenly switched on.

description: A general form of $N$-dark soliton solutions of the multi-component Mel'nikov system is presented. Taking the coupled Mel'nikov system comprised of two-component short waves and one-component long wave as an example, its general $N$-dark-dark soliton solutions in Gram determinant form are constructed through the KP hierarchy reduction method. The dynamics of single dark-dark soliton and two dark-dark solitons are discussed in detail. It can be shown that the collisions of dark-dark solitons are elastic and energies of the solitons in different components completely transmit through. In addition, the dark-dark soliton bound states including both stationary and moving cases are also investigated. An interesting feature for the coupled Mel'nikov system is that the stationary dark-dark soliton bound states can exist for all possible combinations of nonlinearity coefficients including all-positive, all-negative and mixed types, while the moving case are possible when they take opposite signs or they are both negative. The dynamics and several interesting structures of the solutions are illustrated through some figures.

description: We study cosmic shear statistics using the ray-tracing simulation combined with a set of large $N$-body simulations. In this contribution, we first describe our method. Then we show some selected results especially focusing on effects of the deflection of light rays and the lens-lens coupling which are neglected in making the theoretical predictions of the cosmic shear statistics.
