description: Under high pressures, phase transition, as well as deformation twins, are constantly reported in many BCC metals, whose interactions are of fundamental importance to understand strengthen mechanism of these metals under extreme conditions. However, the interactions between twins and phase transition in BCC metals are remain largely unexplored. In this work, interactions between coherent twin boundaries and $α\to ε$ phase transition of iron are investigated using both non- equilibrium molecular dynamics simulations and nudge elastic band method. Mechanisms of both twin-assisted phase transition and reverse phase transition are studied and orientation relationships between BCC and HCP phase are found to be <11-1>BCC || HCP and <1-10>BCC || <0001>HCP for both cases. The twin boundary corresponds to after the phase transition. It is amazing that the reverse transition seems to be able to "memory" and recover the initial BCC twins. The memory would partly loss when plastic slips take place in the HCP phase before the reverse transition. In the recovered initial BCC twins, three major twin spacing are observed, which are well explained in terms of energy barriers of the transition from HCP phase to BCC twin. Besides, variant selection rule of the twin assisted phase transition is also discussed. The results of present work could be expected to give some clues for producing ultra-fine grain structure in materials exhibiting martensitic phase transition.

description: There is an overprovision of chemicals for the control of plant diseases. But owing to rising consciousness, these chemicals, on account of their ill-effects, are being put on hold. Rather, emphasis is being laid on bio-controlling agents and making use of eco-friendly & safe alternative methods.Andrographis paniculata has been used in traditional Siddha and Ayurvedic systems of medicine in India since medieval times. It has been popular even in tribes of India and elsewhere for multiple clinical applications. During present investigation, chemical characterization and efficacy of Andrographis paniculata were observed, in vitro, on seed borne fungi Aspergillus and Rhizopus. The growth of the fungal species was inhibited significantly (p<0.02) with both alcoholic as well as water extract of all ages and of the concentrations used. The alcoholic leaf extracts of Andrographis paniculatawere more effective in comparison to aqueous extract as long as the growth retardation of Rhizopus and Aspergillus was concerned. However, in separate experiments, the crude aqueous and alcoholic leaf extracts of Andrographis paniculatawere found to be inhibitorier for Aspergillus as compared to Rhizopus in the artificial culture media. Leaf extracts of Andrographis paniculata are easy on pocket, environmentally safe, assure fine crop yield and are unswerving to guard the crops against fungal infestations.

description: Cytological studies were carried out on Himalayan green pigeon, Treron phoenicoptera (Columbidae : Columbiformes : Aves). Sixteen males and twelve females were sacrificed and their bone-marrow cells extracted through a sternal puncture. Cells were treated in hypotonic saline, fixed in 1:3 aceto-alcohol and stained in Giemsa. Chromosomes were classified according to Levan et al (1964).In all, one hundred thirty three cellular plates were examined and the modal diploid count was found to be 76+3. There were seven pairs of macrochromosomes, including a pair of sex element (ZZ in case of male and ZW in case of female individuals). All, with clearly defined size and centromeric position, could be easily recognized.A total number of thirty-one pairs formed a gradated series of elements, whose morphology could not be resolved, and have been included in the category of microchromosomes. They comprised 45.6% of TCL. Both the sex chromosomes - Z & W has centromeres at their median point, however, Z is a macrochromosome { Relative Length (LR) = 11.82% ; IC = 49.19 }, whereas, W is the largest microchromosome (LR = 6.67% ; IC = 40.45).Among the twenty eight adult individuals examined, eight karyotypic combinations, irrespective of sex, were observed. In majority of cases, chromosome I and II had centromere in their median region. However, owing to gradual shift in the position of centromere, 8 different chromosome morphs ( Im Im IIm IIm, Im Im IIm IIst, Im Im IIst IIst, Im Ist IIst IIst, Ist Im IIm IIm, Ist Ist IIm IIm, Ist Ist IIst IIm, Ist Ist IIst IIst ) were encountered. According to Garg & Garg [1] [2] [3] [4] [5] [6] [7] [8] [9] and Garg et. al., [10] [11] [12], presence of such widespread inversion polymorphism in Treron phoenicoptera suggests that it may confer an adaptive advantage on the species.

description: To achieve near-zero training error in a classification problem, the layers of a feed-forward network have to disentangle the manifolds of data points with different labels, to facilitate the discrimination. However, excessive class separation can bring to overfitting since good generalisation requires learning invariant features, which involve some level of entanglement. We report on numerical experiments showing how the optimisation dynamics finds representations that balance these opposing tendencies with a non-monotonic trend. After a fast segregation phase, a slower rearrangement (conserved across data sets and architectures) increases the class entanglement.The training error at the inversion is stable under subsampling, and across network initialisations and optimisers, which characterises it as a property solely of the data structure and (very weakly) of the architecture. The inversion is the manifestation of tradeoffs elicited by well-defined and maximally stable elements of the training set, coined ``stragglers'', particularly influential for generalisation.

description: Understanding the magnetic excitations in high-transition temperature (high-$T_c$) copper oxides is important because they may mediate the electron pairing for superconductivity. By determining the wavevector ({\bf Q}) and energy ($\hbarω$) dependence of the magnetic excitations, one can calculate the change in the exchange energy available to the superconducting condensation energy. For the high-$T_c$ superconductor YBa$_2$Cu$_3$O$_{6+x}$, the most prominent feature in the magnetic excitations is the resonance. Although the resonance has been suggested to contribute a major part of the superconducting condensation, the accuracy of such an estimation has been in doubt because the resonance is only a small portion of the total magnetic scattering. Here we report an extensive mapping of magnetic excitations for YBa$_2$Cu$_3$O$_{6.95}$ ($T_c\approx 93$ K). Using the absolute intensity measurements of the full spectra, we estimate the change in the magnetic exchange energy between the normal and superconducting states and find it to be about 15 times larger than the superconducting condensation energy. Our results thus indicate that the change in the magnetic exchange energy is large enough to provide the driving force for high-$T_c$ superconductivity in YBa$_2$Cu$_3$O$_{6.95}$.

What Do We Really Need to Know? Balancing User Data Privacy vs Quality of Service vs Impact Reporting
Creators: name: Klump, Jens
Publisher: name: Zenodo
Year: 2023

description: Data repositories  play a crucial role in supporting open data and open science by curating datasets and providing access services. Monitoring the usage of data repositories has traditionally involved simply logging access to datasets and collecting user feedback. New advancements in IT tools now enable finer-grained usage monitoring, offering a clearer picture of data centre usage and facilitating improved funding prospects. At the same time, funders increasingly ask for more detailed usage statistics to gauge the impact of the services provided by a data centre.

Enhanced usage statistics can include finer geographical resolution and capture the purpose of data access, aiding funders and stakeholders in assessing the impact and outcomes of research infrastructures. Identifying indicators such as publications, citations, user satisfaction, scientific user demographics, open data use, and data sharing can provide valuable insights.

However, the implementation of more granular user identification and usage tracking may introduce barriers to data access. Concerns regarding costs, privacy legislation compliance, and the feasibility of providing detailed user information have also been raised.
This BoF explores the feasibility and benefits of implementing more detailed statistics and tracking mechanisms in data repositories without compromising user data privacy and aims to shed light on the opportunities and challenges associated with enhancing usage monitoring, and the need to balance these with implications for open science and data-driven research.

To address these challenges, a panel discussion involving representatives from different stakeholder groups will be conducted. The panellists will present their perspectives, followed by moderated discussions and audience questions.

A Bregman-Kaczmarz method for nonlinear systems of equations

description: We propose a new randomized method for solving systems of nonlinear equations, which can find sparse solutions or solutions under certain simple constraints. The scheme only takes gradients of component functions and uses Bregman projections onto the solution space of a Newton equation. In the special case of euclidean projections, the method is known as nonlinear Kaczmarz method. Furthermore, if the component functions are nonnegative, we are in the setting of optimization under the interpolation assumption and the method reduces to SGD with the recently proposed stochastic Polyak step size. For general Bregman projections, our method is a stochastic mirror descent with a novel adaptive step size. We prove that in the convex setting each iteration of our method results in a smaller Bregman distance to exact solutions as compared to the standard Polyak step. Our generalization to Bregman projections comes with the price that a convex one-dimensional optimization problem needs to be solved in each iteration. This can typically be done with globalized Newton iterations. Convergence is proved in two classical settings of nonlinearity: for convex nonnegative functions and locally for functions which fulfill the tangential cone condition. Finally, we show examples in which the proposed method outperforms similar methods with the same memory requirements.

description: Using the Matsubara Green's function formalism we calculate the temperature dependence of the nonequilibrium spin polarization induced by an external electric field in the presence of spin-orbit coupling. The model Hamiltonian includes an isotropic k-cubed form of the Rashba spin-orbit interaction. Such a Hamiltonian captures the electronic and spin properties of two-dimensional electron (hole) gas at the surfaces or interfaces of transition metal oxides or in p-doped semiconductor heterostructures. The induced spin polarization is calculated for the nonmagnetic as well as magnetic electron/hole gas. Relation of the spin polarization to the Berry curvature is also discussed.

(2006), published a paper, where they used superposed epoch analyses method to study solar wind features during 549 geomagnetic storms. Unfortunately, the used methodical approach has not allowed to improve essentially understanding of relation of magnetic storms with conditions in the solar wind, and first of all for the following reasons: (1) they did not take into account of existance of storms generated by different types of solar wind, and (2) they took minimum Dst index time as epoch zero time rather than storm onset.

description: This work studies the behaviors of two large-population teams competing in a discrete environment. The team-level interactions are modeled as a zero-sum game while the agent dynamics within each team is formulated as a collaborative mean-field team problem. Drawing inspiration from the mean-field literature, we first approximate the large-population team game with its infinite-population limit. Subsequently, we construct a fictitious centralized system and transform the infinite-population game to an equivalent zero-sum game between two coordinators. We study the optimal coordination strategies for each team via a novel reachability analysis and later translate them back to decentralized strategies that the original agents deploy. We prove that the strategies are $ε$-optimal for the original finite-population team game, and we further show that the suboptimality diminishes when team size approaches infinity. The theoretical guarantees are verified by numerical examples.

The generator of the local gauge symmetry, which cannot be derived from the lagrangian of the enlarged theory, is obtained by making a canonical transformation. We also show that the massless Thirring model possesses a similar local gauge symmetry for a speific value of the coupling constant.

description: The tailoring of the physical properties of semiconductor nanomaterials by strain has been gaining increasing attention over the last years for a wide range of applications such as electronics, optoelectronics and photonics. The ability to introduce deliberate strain fields with controlled magnitude and in a reversible manner is essential for fundamental studies of novel materials and may lead to the realization of advanced multi-functional devices. A prominent approach consists in the integration of active nanomaterials, in thin epitaxial films or embedded within carrier nanomembranes, onto Pb(Mg1/3Nb2/3)O3-PbTiO3-based piezoelectric actuators, which convert electrical signals into mechanical deformation (strain). In this review, we mainly focus on recent advances in strain-tunable properties of self-assembled InAs quantum dots embedded in semiconductor nanomembranes and photonic structures. Additionally, recent works on other nanomaterials like rare-earth and metal-ion doped thin films, graphene and MoS2 or WSe2 semiconductor two-dimensional materials are also reviewed. For the sake of completeness, a comprehensive comparison between different procedures employed throughout the literature to fabricate such hybrid piezoelectric-semiconductor devices is presented. Very recently, a novel class of micro-machined piezoelectric actuators have been demonstrated for a full control of in-plane stress fields in nanomembranes, which enables producing energy-tunable sources of polarization-entangled photons in arbitrary quantum dots. Future research directions and prospects are discussed.

Trialling Collective Access as a data curation and hosting platform
Creators: name: Laverick, Mike
Publisher: name: Zenodo
Year: 2023

description: This talk explores our recent exploration into supporting a University of Auckland archaeology research group to curate and host their project data using Collective Access - a use case that is becoming more and more common.

The nearly decade-long archaeology project uncovered over 200K artefacts with associated metadata, and while their data volume isn't "large" (~50GB) the data is complex: metadata-rich, highly relational, and includes geospatial information. Data was spread across shapefiles, CSVs, and media files, which were shared across and worked on by multiple researchers over several years.

Could the curation process and workflows be improved for new and ongoing projects? How could this data be shared while respecting restrictions around culturally sensitive data? We set out to trial Collective Access (CA) as a solution to these issues, and the more general topics of data curation and hosting.

We report back our efforts, experience, successes, and sticking points with undertaking this project and hope it helps others who attempt to tackle similar scenarios.

description: Traffic flows are studied in terms of their noise of sound, which is an easily accessible experimental quantity. The sound noise data is studied making use of scaling properties of wavelet transforms and Hurst exponents are extracted. The scaling behavior is used to characterize the traffic flows in terms of scaling properties of the memory function in Mori-Lee stochastic differential equations. The results obtained provides for a new theoretical as well as experimental framework to characterize the large-time behavior of traffic flows. The present paper outlines the procedure by making use of one-lane computer simulations as well as sound-data measurements from a real two-lane traffic flow. We find the presence of conventional diffusion as well as 1/f-noise in real traffic flows at large time scales.

description: The massive amounts of data generated by camera sensors motivate data processing inside pixel arrays, i.e., at the extreme-edge. Several critical developments have fueled recent interest in the processing-in-pixel-in-memory paradigm for a wide range of visual machine intelligence tasks, including (1) advances in 3D integration technology to enable complex processing inside each pixel in a 3D integrated manner while maintaining pixel density, (2) analog processing circuit techniques for massively parallel low-energy in-pixel computations, and (3) algorithmic techniques to mitigate non-idealities associated with analog processing through hardware-aware training schemes. This article presents a comprehensive technology-circuit-algorithm landscape that connects technology capabilities, circuit design strategies, and algorithmic optimizations to power, performance, area, bandwidth reduction, and application-level accuracy metrics. We present our results using a comprehensive co-design framework incorporating hardware and algorithmic optimizations for various complex real-life visual intelligence tasks mapped onto our P2M paradigm.
Image Processing Portal (IPP): A web-based solution for efficient processing of large-scale microscopy data
Creators: name: Endrei, Mark
Publisher: name: Zenodo
Year: 2023

description: Modern light-sheet microscopy techniques have made it possible to capture images of biological systems with high spatial resolution over lengthy time-lapse intervals, frequently resulting in the generation of terabytes of data in a single experiment. This drives the need for effective tools and expertise for image data management, processing, and analysis.

To address this challenge, we have developed Image Processing Portal (IPP), a web-based application in collaboration with the Metropolitan Data Caching Infrastructure (MeDICI) at the University of Queensland (UQ). IPP makes it possible for non-computer science researchers to perform microscopy image analysis using organizational High-Performance Computing (HPC) resources without the need for command-line expertise.

IPP streamlines tasks involving massively parallel image processing on GPU-accelerated HPC systems. The portal allows users to handle their experimental data on HPC clustered file systems interactively from within the browser. Users can process image files using a range of tools, including file converters, batch processing, and deskewing with a few mouse clicks. Users can download and execute macros from shared repositories to process image transformations such as Z-projection without needing to use the command line interface. Additionally, a custom metadata scraper is being implemented to accurately read additional image metadata to perform deconvolution all through a web interface.

With the IPP, any researcher with an interest in microscopy is now able to use high performance computing resources to perform image-processing tasks with terabyte-scale datasets without any of the experience required to use the command line tools.
Thermodynamics of the BCS-BEC crossover

description: We present a self-consistent theory for the thermodynamics of the BCS-BEC crossover in the normal and superfluid phase which is both conserving and gapless. It is based on the variational many-body formalism developed by Luttinger and Ward and by DeDominicis and Martin. Truncating the exact functional for the entropy to that obtained within a ladder approximation, the resulting self-consistent integral equations for the normal and anomalous Green functions are solved numerically for arbitrary coupling. The critical temperature, the equation of state and the entropy are determined as a function of the dimensionless parameter $1/k_Fa$, which controls the crossover from the BCS-regime of extended pairs to the BEC-regime of tightly bound molecules. The tightly bound pairs turn out to be described by a Popov-type approximation for a dilute, repulsive Bose gas. Even though our approximation does not capture the critical behaviour near the continuous superfluid transition, our results provide a consistent picture for the complete crossover thermodynamics which compare well with recent numerical and field-theoretic approaches at the unitarity point.

The temperature drop in the microchannel decreases with an increase in the aspect ratio whereas it increases with an increase in the pressure ratio, the cross-aspect ratio (CAR), and the Knudsen number. 3D and 2D simulations results are compared and effect of the CAR and Knudsen number are brought out. Finally, a correlation that predicts the temperature drop is formulated along with a list of conditions that ensures a near isothermal flow.

description: In the present paper, we show that elliptical galaxies (Es) obey a scaling relation between potential energy and mass. Since they are relaxed systems in a post violent-relaxation stage, they are quasi-equilibrium gravitational systems and therefore they also have a quasi-constant specific entropy. Assuming that light traces mass, these two laws imply that in the space defined by the three Sérsic law parameters (intensity Sigma_0, scale a and shape nu), elliptical galaxies are distributed on two intersecting 2-manifolds: the Entropic Surface and the Energy-Mass Surface. Using a sample of 132 galaxies belonging to three nearby clusters, we have verified that ellipticals indeed follow these laws. This also implies that they are distributed along the intersection line (the Energy-Entropy line), thus they constitute a one-parameter family. These two physical laws (separately or combined), allow to find the theoretical origin of several observed photometrical relations, such as the correlation between absolute magnitude and effective surface brightness, and the fact that ellipticals are located on a surface in the [log R_eff, -2.5 log Sigma_0, log nu] space. The fact that elliptical galaxies are a one-parameter family has important implications for cosmology and galaxy formation and evolution models. Moreover, the Energy-Entropy line could be used as a distance indicator.

Building infrastructure for sensitive data workloads
Creators: name: Mallon, Michael
Publisher: name: Zenodo

description: Security of infrastructure is an increasingly important domain. Obligations and requirements from users, organisations and governments are ever increasing. As this trend continues, these obligations will morph into more formal certification requirements. Over the past two years, the Queensland Cyber Infrastructure Foundation (QCIF) in partnership with The University of Queensland (UQ) have been developing a platform for the analysis of sensitive data, Keypoint. In this talk I will discuss the OpenStack restricted region that we have built in partnership with the Australian Research Data Commons (ARDC) to support this platform.

Regions are a method of dividing up resources in an OpenStack cloud. Regions are full OpenStack deployments with their own set of endpoints, however, they share a common identity service (Keystone). What makes this new region restricted is the choices we have made with regards to who has access, how they access it and what services we provide in the region, as compared with the standard ARDC Research Cloud region. These choices were made with the aim of reducing the burden of achieving certifications, such as the ISO27000 family, for the platforms that run in this region. While this talk will be grounded in the context of an OpenStack environment, the core concepts that we grappled with are applicable to any cloud or virtual environment.

description: By making use of Schwinger's oscillator model of angular momentum, we put forward an interesting connection among three solvable Hamiltonians, widely used for discussions on the quantum measurement problem. This connection implies that a particular macroscopic limit has to be taken for these models to be physically sensible.

description: The present work reports the preparation of wood protective polyurethane (PU) from mahua oil-based polyetheramide polyol and its performance evaluation. The synthesis of polyetheramide polyol was carried out in two steps: the first step deals with the synthesis of mahua oil fatty amide (MFA) from mahua oil by base catalyzed aminolysis reaction and the second step deals with the synthesis of polyetheramide polyol from diglycidyl ether of bisphenol-A (DGEBA) and MFA. The structure of the synthesized polyetheramide polyol was confirmed by the Attenuated total reflection fourier transform infrared (ATR-FTIR) and proton nuclear magnetic resonance (1H NMR) spectroscopy. The synthesized polyetheramide polyol was used as a precursor for the wood protective PU coatings. The performance of the prepared wood protective PU coatings was evaluated by the measurements of the various performance properties. The results reveal that mechanical, thermal, and microbial properties of the prepared PUs are satisfactory compared to other literature reported vegetable oil-based PUs; whereas, water, solvent, and chemical resistance of the prepared PUs are quite good. The study concludes that mahua oil-based polyetheramide polyol is a suitable precursor for the preparation of wood protective PU.
Depolarizing field and "real" hysteresis loops in nanometer-scale ferroelectric films

description: We give detailed analysis of the effect of depolarizing field in nanometer-size ferroelectric capacitors studied by Kim et al. [Phys. Rev. Lett. 95, 237602 (2005)]. We calculate a critical thickness of the homogeneous state and its stability with respect to domain formation for strained thin films of BaTiO3 on SrRuO3/SrTiO3 substrate within the Landau theory. While the former (2.5nm) is the same as given by ab-initio calculations, the actual critical thickness is set by the domains at 1.6nm. There is a large Merz's activation field for polarization relaxation. Remarkably, the results show a_negative_ slope of the "actual" hysteresis loops, a hallmark of the domain structures in ideal thin films with imperfect screening.

Single-step synthesis of N-doped TiO2 by flame aerosol method and the effect of synthesis parameters

description: We have established a novel route for the synthesis of N-doped TiO2 by adopting flame aerosol (FSP) technique and investigated the effect of water content on the physico-chemical properties of the as-synthesized nanoparticles. The key characteristics of the developed method are to modify the precursor solution in order to incorporate nitrogen atoms into the TiO2 lattice without altering the FSP set-up. The reduction of the flame enthalpy resulting in N-incorporation into the TiO2 and the N-doping can be greatly enhanced further by the addition of secondary N-source (urea). Our XRD results reveal a shift of the (101) plane anatase diffraction peak to lower angles in our N-doped TiO2 compared to undoped TiO2, which suggest the distortion and strain in the crystal lattice prompted by the incorporation of the nitrogen atoms. The growth or expansion of crystal lattice can be attributed to the larger atomic radius of respective nitrogen atoms (r = 1.7 Å) compared to oxygen (r = 1.40 Å). Our XPS and EDX spectroscopy results elucidate that the nitrogen was effectively doped into the crystal lattice of TiO2 in our as-synthesized N-TiO2 catalysts predominantly in the form of interstitial nitrogen (Ti−O−N). The nitrogen atoms incorporation into the crystal lattice of titania modifies the electronic band structure of TiO2, resulting in a new mid-gap energy state N 2p band formed above O 2p valence band. This occurrence narrows the band gap of TiO2 (from 3.12 to ∼2.51 eV) in our N-doped TiO2 and shifts the optical absorption to the visible region.

description: Surfaces of homoepitaxially grown TiO2-terminated SrTiO3(001) were studied in situ with scanning tunneling microscopy and spectroscopy. By controlling the Ti/Sr ratio, two-dimensional domains of highly ordered linear nanostructures, so-called "nanolines", are found to form on the surface. To further study how the surface structure affects the band structure, spectroscopic studies of these surfaces were performed. Our results reveal significantly more band bending for surfaces with the nanolines, indicative of an acceptor state associated with these features. Additionally, an in-gap state is observed on nanoline surfaces grown under high oxygen deficient conditions. This state appears to be the same as that observed previously, arising from the (++/+) transition level of surface oxygen vacancies.

Simulating Quantum Computing on Traditional HPC Systems: Developing Tomorrow's Quantum Algorithms on Today's CMOS Hardware
Creators: name: Scholz, Werner
Publisher: name: Zenodo
Year: 2023

description: The field of quantum computing is receiving growing attention for its potential to break some barriers of traditional CMOS-based hardware. While practical quantum computers are still under development using a variety of different approaches and physical implementations of their fundamental compute elements (qubits), simulating quantum computing on traditional High-Performance Computing (HPC) systems has emerged as a valuable approach for gaining insights into quantum systems and algorithms. This presentation explores the systems, solutions, and software stacks available today for the simulation of quantum computers on HPC systems.

We will provide an overview of quantum computing simulation techniques and the challenges involved as well as some of the hardware and software available today to run quantum simulations. Recent advances in standard CMOS-based hardware and especially powerful accelerators have increased the size of quantum computer systems which can be simulated, but there are still limits to both the system size and fidelity of the simulations. A variety of simulation tools/frameworks/SDKs are available  and we will review their capabilities, challenges, and limitations.

By attending this presentation, participants will gain insights how traditional HPC systems can be leveraged for the simulation of quantum computing systems and some of the important considerations for choosing the right platform for the development of quantum computing algorithms while awaiting the advent of practical quantum hardware.
Vortices on Higher Genus Surfaces

description: We consider the topological interactions of vortices on general surfaces. If the genus of the surface is greater than zero, the handles can carry magnetic flux. The classical state of the vortices and the handles can be described by a mapping from the fundamental group to the unbroken gauge group. The allowed configurations must satisfy a relation induced by the fundamental group. Upon quantization, the handles can carry ``Cheshire charge.'' The motion of the vortices can be described by the braid group of the surface. How the motion of the vortices affects the state is analyzed in detail.
