description: We investigate the nonlinear interaction between two laser beams in a plasma in the weakly nonlinear and relativistic regime. The evolution of the laser beams is governed by two nonlinear Schroedinger equations that are coupled with the slow plasma density response. We study the growth rates of the Raman forward and backward scattering instabilities as well of the Brillouin and self-focusing/modulational instabilities. The nonlinear evolution of the instabilities is investigated by means of direct simulations of the time-dependent system of nonlinear equations.

description: In this research we used bio-inspired metaheuristics, as artificial immune systems and ant colony algorithms that are based on a number of characteristics and behaviors of living things that are interesting in the computer science area. This paper presents an evaluation of bio-inspired solutions to combinatorial optimization problem, called the Job Shop Scheduling or planning work, in a simple way the objective is to find a configuration or job stream that has the least amount of time to be executed in machine settings. The performance of the algorithms was characterized and evaluated for reference instances of the job shop scheduling problem, comparing the quality of the solutions obtained with respect to the best known solution of the most effective methods. The solutions were evaluated in two aspects, first in relation of quality of solutions, taking as reference the makespan and secondly in relation of performance, taking the number evaluations performed by the algorithm to obtain the best solution.

description: This paper is concerned with theories describing spinning particles that are formulated in terms of actions possessing either local world-line supersymmetry or local fermionic {\it kappa} invariance. These classical actions are obtained by adding a finite number of spinor or vector coordinates to the usual space-time coordinates. Generalizing to superspace leads to corresponding types of \lq spinning superparticle' theories in which the wave-functions are superfields in some (generally reducible) representation of the Lorentz group. A class of these spinning superparticle actions possesses the same spectrum as ten-dimensional supersymmetric Yang--Mills theory, which it is shown can be formulated in terms of either vector or spinor superfields satisfying supercovariant constraints. The models under consideration include some that were known previously and some new ones.

Magnetic-distortion-induced ellipticity and gravitational wave radiation of neutron stars: millisecond magnetars in short GRBs, Galactic pulsars, and magnetars

description: Neutron stars may sustain a non-axisymmetric deformation due to magnetic distortion and are potential sources of continuous gravitational waves (GWs) for ground-based interferometric detectors. With decades of searches using available GW detectors, no evidence of a GW signal from any pulsar has been observed. Progressively stringent upper limits of ellipticity have been placed on Galactic pulsars. In this work, we use the ellipticity inferred from the putative millisecond magnetars in short gamma-ray bursts (SGRBs) to estimate their detectability by current and future GW detectors. For $\sim 1$ ms magnetars inferred from the SGRB data, the detection horizon is $\sim 30$ Mpc and $\sim 600$ Mpc for advanced LIGO (aLIGO) and Einstein Telescope (ET), respectively. Using the ellipticity of SGRB millisecond magnetars as calibration, we estimate the ellipticity and gravitational wave strain of Galactic pulsars and magnetars assuming that the ellipticity is magnetic-distortion-induced. We find that the results are consistent with the null detection results of Galactic pulsars and magnetars with the aLIGO O1. We further predict that the GW signals from these pulsars/magnetars may not be detectable by the currently designed aLIGO detector. The ET detector may be able to detect some relatively low frequency signals ($<50$ Hz) from some of these pulsars. Limited by its design sensitivity, the eLISA detector seems not suitable for detecting the signals from Galactic pulsars and magnetars.

description: The percolation properties of clustered networks are analyzed in detail. In the case of weak clustering, we present an analytical approach that allows to find the critical threshold and the size of the giant component. Numerical simulations confirm the accuracy of our results. In more general terms, we show that weak clustering hinders the onset of the giant component whereas strong clustering favors its appearance. This is a direct consequence of the differences in the $k$-core structure of the networks, which are found to be totally different depending on the level of clustering. An empirical analysis of a real social network confirms our predictions.

description: When chiral liquid crystals or magnets are subjected to applied fields or other anisotropic environments, the competition between favored twist and anisotropy leads to the formation of complex defect structures. In some cases, the defects are skyrmions, which have 180° double twist going outward from the center, and hence can pack together without singularities in the orientational order. In other cases, the defects are merons, which have 90° double twist going outward from the center; packing such merons requires singularities in the orientational order. In the liquid crystal context, a lattice of merons is regarded as a blue phase. Here, we perform theoretical and computational studies of skyrmions and merons in chiral liquid crystals and magnets. Through these studies, we calculate the phase diagrams for liquid crystals and magnets in terms of dimensionless ratios of energetic parameters. We also predict the range of metastability for liquid crystal skyrmions, and show that these skyrmions can move and interact as effective particles. The results show how the properties of skyrmions and merons depend on the vector or tensor nature of the order parameter.

description: The 2022 National Research Infrastructure Roadmap provides a clear path for Australia to build on strong existing foundations and deliver step-changes to support future national needs. The Australian Research Data Commons (ARDC) launched the Planet Research Data Commons (Planet RDC) in 2022-2023 to collaboratively develop and deliver sustainable digital research infrastructure for the earth and environmental sciences on a national scale.

Our nationwide consultation process identified the following significant data challenges: "Trusted Data Supply Chains," "Integrated Datasets and Services," "Modelling, Analytics, and Decision-Support Infrastructure," and "FAIR, CARE and Indigenous Data Governance." To address these data challenges, the Planet RDC is working with governments, universities, industry, and our partners in the National Earth and Environmental Science Facilities Forum (NEESFF) and beyond.

We will present our 5 year vision and outline the most recent developments of the Planet RDC. For example, with industry and government partners, we co-designed a process to define and map an environmental data and information supply chain, and will be piloting this with exemplar projects. We are working with NCRIS partners to enable federated discovery of and access to National Virtual Collections, and to create a skills framework. We have begun developing our modelling, analytics and decision support infrastructure by building on and enhancing existing infrastructure, and we will present our approach to reference architectures. Finally, we will outline our work towards implementing the CARE principles and a common approach to Indigenous data governance with our NEESFF partners.

description: In this year, in which we celebrate 100 years of the cosmological term, $Λ$, in Einstein's gravitational field equations, we are still facing the crucial question whether $Λ$ is truly a fundamental constant or a mildly evolving dynamical variable. After many theoretical attempts to understand the meaning of $Λ$, and in view of the enhanced accuracy of the cosmological observations, it seems now mandatory that this issue should be first settled empirically before further theoretical speculations on its ultimate nature. In this work, we summarize the situation of some of these studies. Devoted analyses made recently show that the $Λ=$const. hypothesis, despite being the simplest, may well not be the most favored one. The overall fit to the cosmological observables $SNIa+BAO+H(z)+LSS+CMB$ singles out the class RVM of the "running" vacuum models, in which $Λ=Λ(H)$ is an affine power-law function of the Hubble rate. It turns out that the performance of the RVM as compared to the "concordance" $Λ$CDM model (with $Λ=$const.) is much better. The evidence in support of the RVM may reach $\sim 4σ$ c.l., and is bolstered with Akaike and Bayesian criteria providing strong evidence in favor of the RVM option. We also address the implications of this framework on the tension between the CMB and local measurements of the current Hubble parameter.

We find a period of $16.4\pm0.2~$hr and a peak-to-peak amplitude of $1.07\pm0.04\%$ for W0047, and a period of $11\pm2~$hr and amplitude of $0.8\pm 0.2\%$ for 2M2244. This period is significantly longer than that measured previously during a shorter observation. {We additionally detect significant $J$-band variability in 2M2244 using the Wide-Field Camera on UKIRT. } We determine the radial and rotational velocities of both objects using Keck NIRSPEC data. We find a radial velocity of $-16.0_{-0.9}^{+0.8}~$km s$^{-1}$ for 2M2244, and confirm it as a bona fide member of the AB Doradus moving group. We find rotational velocities of $v \sin i=9.8\pm0.3~$km s$^{-1}$and $14.3^{+1.4}_{-1.5}~$km s$^{-1}$ for W0047 and 2M2244, respectively. With inclination angles of $85 ^{+5\circ}_{-9}$ and $76 ^{+14\circ}_{-20}$, W0047 and 2M2244 are viewed roughly equator-on. Their remarkably similar colours, spectra and inclinations are consistent with the possibility that viewing angle may influence atmospheric appearance. We additionally present \textit{Spitzer} $[4.5~μ\mathrm{m}]$ monitoring of the young, T5.5 object SDSS111010+011613 (SDSS1110) where we detect no variability. For periods $<18~$hr, we place an upper limit of $1.25\%$ on the peak-to-peak variability amplitude of SDSS1110.

We derive an analytical expression for the universal scaling factor and use this to calculate domain wall thickness and gradient coefficients (exchange constants) in some ferroic materials. We then use these to discuss some of the wider implications for the physics of ferroelectric nano-devices and periodically poled photonic crystals.

Knitting jumpers from steel wool and spaghetti: implementing a modified Darwin Core Event model for the Australian Reference Genome Atlas (ARGA) to increase trust through provenance.
Creators: name: Hall, Kathryn
Publisher: name: Zenodo
Year: 2023

description: Trust is a key concern for researchers who work in data-intensive fields; if they cannot trust data they find, they are unlikely to reuse it.  Addressing data trustability is a core imperative for the Australian Reference Genome Atlas (ARGA).  New architecture to integrate genomics data from domain-specific repositories with Darwin Core formatted occurrence records, and other biodiversity data, from collectories lies at the digital heart of ARGA.

Problematically, each data type indexed by ARGA is generated from source biologicals using its own method; some of these data are raw, some are derivatives, some are aggregates.  While data reuse within the biosciences is not restricted to primary data (indeed often secondary or tertiary data are preferred), it is critically important that clear provenance chains are visible to researchers to inform their discernment processes.  Repositories for genomics data, such as NCBI GenBank, have historically been built with an emphasis on the molecular datasets themselves, providing complex metadata around annotations, but not explicitly recording methodology and source materials in detail.

Foundational work by ARGA integrates data from these two different structures, via a series of ingestion scripts implementing customised field mappings, to harmonise both data sources within an extended Event framework.  Here we demonstrate our mapping process and detail how we have woven the two data structures together to form a coherent whole for genomics data.  In creating a hybrid framework, ARGA transforms genomics data and their metadata, and enriches it with trusted organismal provenances, to enable discoverability within biological and ecological contexts.

description: We investigate gravitational correlation functions in a curved background with the help of nonperturbative renormalization group methods. Beta functions for eleven couplings are derived, two of which correspond to running gauge parameters. A unique ultraviolet fixed point is found, suitable for a UV completion in the sense of Asymptotic Safety. To arrive at a well-behaved flow in a curved background, the regularization must be chosen carefully. We provide two admissible choices to solve this issue in the present approximation. We further demonstrate by an explicit calculation that the Landau limit is a fixed point also for quantum gravity, and additionally show that in this limit, the gauge parameter $β$ does not flow.

description: Most people can recognize and perform a musical piece under a variety of transformations such as altering the key or varying the tempo. However, we also know that other mental transformations of music can be difficult to generate and to recognize. Two factors that might affect this mental flexibility are the familiarity of the piece and musical ability of the listener, in this case singing accuracy. The current experiment addressed the accuracy and flexibility of representations of novel and traditional melodies among accurate, moderate, and inaccurate singers. Participants sang or recognized melodies in either their original form or as a transformation: a transposition, a shift of serial position, and a reversal of the melody. Participants showed an advantage for traditional melodies, but only when singing or recognizing tunes in their original form. Participants were similarly disrupted by mental transformations of traditional and novel tunes in both production and recognition tasks. Interestingly, we found that the only advantage for traditional melodies when singing repetitions of the melody occurred among the moderate singers, but all three groups showed an advantage for traditional melodies when recognizing exact repetitions.

description: We explore novel gauge enhancements from abelian to non-simply-connected gauge groups in F-theory. To this end we consider complex structure deformations of elliptic fibrations with a Mordell--Weil group of rank one and identify the conditions under which the generating section becomes torsional. For the specific case of Z2 torsion we construct the generic solution to these conditions and show that the associated F-theory compactification exhibits the global gauge group [SU(2) x SU(4)]/Z2 x SU(2). The subsolution with gauge group SU(2)/Z2 x SU(2), for which we provide a global resolution, is related by a further complex structure deformation to a genus-one fibration with a bisection whose Jacobian has a Z2 torsional section. While an analysis of the spectrum on the Jacobian fibration reveals an SU(2)/Z2 x Z2 gauge theory, reproducing this result from the bisection geometry raises some conceptual puzzles about F-theory on genus-one fibrations.

description: The Murchison Widefield Array (MWA), located in Western Australia, is one of the low-frequency precursors of the international Square Kilometre Array (SKA) project. In addition to pursuing its own ambitious science program, it is also a testbed for wide range of future SKA activities ranging from hardware, software to data analysis. The key science programs for the MWA and SKA require very high dynamic ranges, which challenges calibration and imaging systems. Correct calibration of the instrument and accurate measurements of source flux densities and polarisations require precise characterisation of the telescope's primary beam. Recent results from the MWA GaLactic Extragalactic All-sky MWA (GLEAM) survey show that the previously implemented Average Embedded Element (AEE) model still leaves residual polarisations errors of up to 10-20 % in Stokes Q. We present a new simulation-based Full Embedded Element (FEE) model which is the most rigorous realisation yet of the MWA's primary beam model. It enables efficient calculation of the MWA beam response in arbitrary directions without necessity of spatial interpolation. In the new model, every dipole in the MWA tile (4 x 4 bow-tie dipoles) is simulated separately, taking into account all mutual coupling, ground screen and soil effects, and therefore accounts for the different properties of the individual dipoles within a tile. We have applied the FEE beam model to GLEAM observations at 200 - 231 MHz and used false Stokes parameter leakage as a metric to compare the models. We have determined that the FEE model reduced the magnitude and declination-dependent behaviour of false polarisation in Stokes Q and V while retaining low levels of false polarisation in Stokes U.

We discuss here in detail a problem of practical interest, particle identification based on time-of-flight or dE/dx information. We show that large biases can occur in estimating particle fractions in a sample if differences between the momentum spectra of particles are ignored, and we present a more robust fit technique, allowing bias-free estimation even when the particle spectra in the sample are unknown.

On the emergence of gauge structures and generalized spin when quantizing on a coset space

Year: 1993
Subjects: subject: High Energy Physics - Theory (hep-th)

description: It has been known for some time that there are many inequivalent quantizations possible when the configuration space of a system is a coset space G/H. Viewing this classical system as a constrained system on the group G, we show that these inequivalent quantizations can be recovered from a generalization of Dirac's approach to the quantization of such a constrained system within which the classical first class constraints (generating the H-action on G) are allowed to become anomalous (second class) when quantizing. The resulting quantum theories are characterized by the emergence of a Yang-Mills connection, with quantized couplings, and new 'spin' degrees of {}freedom. Various applications of this procedure are presented in detail: including a new account of how spin can be described within a path-integral formalism, and how on S^4 chiral spin degrees of {}freedom emerge, coupled to a BPST instanton.

Head out on the HPC Highway: Opening Up HPC to Underrepresented & Cross-Disciplinary Domains
Creators: name: Haseen, Fathima
Publisher: name: Zenodo
Year: 2023

description: SITUATION
"Traditional" domains have historically consumed a lion's share of High Performance Computing (HPC) infrastructure, especially in supercomputing. For example, at the Pawsey Supercomputing Research Centre, almost 70% of super compute allocation goes to Engineering and Physical Sciences projects.

What are the key barriers to entry and/or scaling for underrepresented ("Non-traditional") domains?

TASK
During this Birds of a Feather (BoF), we will discuss the current project demographics on Australia's top supercomputers. The goal is to identify the top perceived barriers to using HPC across all aspects of a project, including the human, technology, and science angles.

ACTION
During this BoF, we'll conduct a short, introductory, data-driven context setter.

We'll then conduct an in-the-room environmental scan of perceived barriers to HPC domain entry as well as challenges to securing HPC allocations within Underrepresented Domains and/or Cross-Disciplinary Domains. We'll use real-time, online means to identify and rank priorities.

Finally, we'll unpack those challenges with the goal of identifying actionable steps resulting from the BoF. Current approaches being taken in this space by BoF presenters will be given as springboards for further discussion and brainstorming.

RESULTS
One key outcome of this BoF is to name the top challenges being faced by Underrepresented and Cross-disciplinary domains, unpack their complexity, and provide ideas to lower - or altogether eliminate - those barriers.

As presenters, we want to leave with next steps to an important question: How can we construct potential "on ramps" into HPC for currently underrepresented domains?
Gravitational Microlensing of Gamma-Ray Burst Afterglows by Single and Binary Stars

description: We calculate the magnification light curves due to stellar microlensing of gamma-ray burst (GRB) afterglows. A GRB source appears on the sky as a thin ring which expands faster than the speed of light and is maximally magnified as it crosses the lens caustics. While a single star lens produces a single peak in the magnification light curve, binary star lenses may produce multiple peaks. The shape of the magnification light curve provides invaluable information on the surface brightness distribution of the afterglow photosphere on sub micro-arcsecond scales. We find that all afterglows are likely to show variability at the level of a few percent about a year following the explosion, due to stars which are separated by tens of Einstein radii from their line-of-sight.

Tricritical directed percolation
Creators: name: Lubeck, S.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We consider a modification of the contact process incorporating higher-order reaction terms. The original contact process exhibits a non-equilibrium phase transition belonging to the universality class of directed percolation. The incorporated higher-order reaction terms lead to a non-trivial phase diagram. In particular, a line of continuous phase transitions is separated by a tricritical point from a line of discontinuous phase transitions. The corresponding tricritical scaling behavior is analyzed in detail, i.e., we determine the critical exponents, various universal scaling functions as well as universal amplitude combinations.

description: Most giant spiral galaxies have pseudo or disk-like bulges that are considered to be the result of purely secular processes. This may challenge the hierarchical scenario predicting about one major merger per massive galaxy ($>$$3\times 10^{10} M_{\odot}$) since the last $\sim$ 9 billion years. Here we verify whether or not the association between pseudo-bulges and secular processes is irrevocable. Using GADGET2 N-body/SPH simulations, we have conducted a systematic study of remnants of major mergers which progenitors have been selected (1) to follow the gas richness-look back time relationship, and (2) with a representative distribution of orbits and spins in a cosmological frame. Analyzing the surface-mass density profile of both nearby galaxies and merger remnants with two components, we find that most of them show pseudo-bulges or bar dominated centers. Even if some orbits lead to classical bulges just after the fusion, the contamination by the additional gas that gradually accumulates to the center and forming stars later on, leads to remnants apparently dominated by pseudo-bulges. We also found that simple SPH simulations should be sufficient to form realistic spiral galaxies as remnants of ancient gas-rich mergers without need for specifically tuned feedback conditions. We then conclude that pseudo-bulges and bars in spiral galaxies are natural consequences of major mergers when they are realized in a cosmological context, i.e., with gas-rich progenitors as expected when selected in the distant Universe.

Evolution of eResearch Services at the University of Canberra
Creators: name: Hemming, Kyle
Publisher: name: Zenodo
Year: 2023
Subjects: Data Management Planning
Engagement

description: Background
eResearch is the interface between information technology and research. Research is increasingly reliant on eResearch tools and technologies. For instance, data is increasingly stored, shared and published online, requiring secure tools and management practices; data analysis increasingly involves statistical and computational technologies, which require technical skills to use.

Problem
Previously, eResearch services at the University of Canberra (UC) were not well publicised or structured. Researchers could not easily locate or access support for using UC-supported tools. Consequently, eResearch services were not well utilised and researchers may have instead been using inappropriate tools or spending longer than necessary troubleshooting technical issues.

Actions
The eResearch Team at the University of Canberra (UC) has reimagined  its eResearch tools and marketing strategies to support UC researchers. The team has remastered its webpage services, developed an online support channel for technical troubleshooting, and actively showcases these services to faculties. From a single online source, researchers can now access information on data management planning, data storage, common analytical tools, high performance computing, and training. Through a Research support channel, researchers can post research queries relating to these areas, monitored by a research community and UC's eResearch team, for bespoke, timely support.

Results
Through these reimagined services, UC researchers can now more easily access and get up to speed in using eResearch tools, to help them during the different stages of their research journey, which should help increase researchers' "time for science" to support their research outputs.

Project Management, Leadership and Skills: Planning and Control
Creators: name: Musa, Eltigani
Publisher: name: Zenodo
Year: 2024

description: Abstract:

Leadership is recognized to be an important concept that has gained particularly significant attention in the 20th century, during which were developed main leadership theories. By the end of the 1990s, there were developed and popularized six major schools of leadership theory, including: the trait school, the behavioral school, the contingency school, the charismatic/visionary school, the emotional intelligence school, and the competency school (Turner & Müller, 2005). Each school has developed a set of criteria, characteristics, competencies, etc. of different types of leadership, which are widely applied in managerial practice until today. These leadership theories are applicable to different organizational context and activities, including project management. Among a variety of existing leadership theories, many researchers suggest that transactional and transformational leadership styles related to the charismatic leadership school are the most commonly practiced and effective styles in project management. The research of this paper also indicates that the right balance of both task-oriented and people-oriented leadership approach is especially relevant to the project management environment, whereas team work is especially important to project success. However, the research also indicates that there is no universal leadership style, which could fit practically any project management context. Different approach of leadership act differently (either worse or better) on different types of change projects and at different life cycle stages of these projects. Therefore, project manager needs to be able to adopt appropriate leadership style in order to achieve positive results, high level of productivity and enhanced team performance. Moreover, in today’s diverse environments, project managers need to be able to adjust to various socio-cultural contexts and adopt appropriate communication style in order to succeed in project implementation.
On the star-forming ability of Molecular Clouds

description: The star-forming ability of a molecular cloud depends on the fraction of gas it can cycle into the dense-phase. Consequently, one of the crucial questions in reconciling star-formation in clouds is to understand the factors that control this process. While it is widely accepted that the variation in ambient conditions can alter significantly the ability of a cloud to spawn stars, the observed variation in the star-formation rate in nearby clouds that experience similar ambient conditions, presents an interesting question. In this work we attempted to reconcile this variation within the paradigm of colliding flows. To this end we develop self-gravitating, hydrodynamic realisations of identical flows, but allowed to collide off-centre. Typical observational diagnostics such as the gas-velocity dispersion, the fraction of dense-gas, the column density distribution ({\small N-PDF}), the distribution of gas mass as a function of $K$-band extinction and the strength of compressional/solenoidal modes in the post-collision cloud were deduced for different choices of the impact parameter of collision. We find that a strongly sheared cloud is terribly inefficient in cycling gas into the dense phase and that such a cloud can possibly reconcile the sluggish nature of star-formation reported for some clouds. Within the paradigm of cloud-formation via colliding flows this is possible in case of flows colliding with a relatively large impact parameter. We conclude that compressional modes - though probably essential - are insufficient to ensure a relatively higher star-formation efficiency in a cloud.

description: Optimal percolation is the problem of finding the minimal set of nodes such that if the members of this set are removed from a network, the network is fragmented into non-extensive disconnected clusters. The solution of the optimal percolation problem has direct applicability in strategies of immunization in disease spreading processes, and influence maximization for certain classes of opinion dynamical models. In this paper, we consider the problem of optimal percolation on multiplex networks. The multiplex scenario serves to realistically model various technological, biological, and social networks. We find that the multilayer nature of these systems, and more precisely multiplex characteristics such as edge overlap and interlayer degree-degree correlation, profoundly changes the properties of the set of nodes identified as the solution of the optimal percolation problem.
