description: What is a DMP?A Data Management Plan (DMP) is a document detailing how the data from a research project is to be managed throughout its lifecycle. This implies describing the techniques, methods and policies on how data is to be created, documented, accessed, preserved and disseminated.
Issues with DMPsNowadays several funding agents require funding applications to be accompanied by a DMP, but than it rarely is required for anything else. Consequently, the DMP is frequently a text document holding a static structure, that once created is rarely revisited. As a result, the DMP is seen more as bureaucratic obligation, than as a valuable asset for data management. However, the DMP can be a major tool to support the application of the FAIR data principles, especially if we can understand it as an alive object.
What is a maDMP?The concept of Machine-Actionable DMP (maDMP), aiming at making the DMP machine-readable without compromising its human-readability can support that vision. The adoption of an open, shared and interoperable concept of maDMP could bring multiple benefits, such as to data discovery and reuse, evaluation and monitoring, etc.
Our Challenge!We propose ELIXIR as a perfect context to experiment this concept! The proposal is the engage ELIXIR in this challenge, promoting the design and development of an open distributed infrastructure that can demonstrate and validate the sharing of good practices for this purpose, by offering templates and services for creating, sharing, reuse and process maDMP, as also to demonstrate new kinds of value.

description: The introduction of synthetic dimensions in topological photonic systems enriches the exploration of topological phase of light in higher-dimensional space beyond three-dimensional real-space. Recently, the gapless corner modes of topological photonic crystals under translational deformation have been proposed, but their experimental observation is still absent. Here, we observe the gapless corner modes in a photonic crystal slab under translational deformation. The corner mode exhibits a frequency dependence that can be tuned through the translation of the slab. Importantly, we find that the existence of gapless corner modes is independent of the specific corner configuration. The gapless corner modes are experimentally imaged via the near-field scanning measurement, and validated numerically by full-wave simulations. Our work contributes to the advancement of topological photonics and provides valuable insights into the exploration of gapless corner modes in synthetic dimensions.
Quantum machine learning for quantum anomaly detection

description: Anomaly detection is used for identifying data that deviate from `normal' data patterns. Its usage on classical data finds diverse applications in many important areas like fraud detection, medical diagnoses, data cleaning and surveillance. With the advent of quantum technologies, anomaly detection of quantum data, in the form of quantum states, may become an important component of quantum applications. Machine learning algorithms are playing pivotal roles in anomaly detection using classical data. Two widely-used algorithms are kernel principal component analysis and one-class support vector machine. We find corresponding quantum algorithms to detect anomalies in quantum states. We show that these two quantum algorithms can be performed using resources logarithmic in the dimensionality of quantum states. For pure quantum states, these resources can also be logarithmic in the number of quantum states used for training the machine learning algorithm. This makes these algorithms potentially applicable to big quantum data applications.

description: We study the phase transition between conducting and insulating states taking place in disordered multi-channel Luttinger liquids with inter-channel interactions. We derive renormalisation group equations which are perturbative in disorder but nonperturbative in interaction. In the vicinity of the simultaneous phase transition in all channels, these equations become a set of coupled Berezinskii--Kosterlitz--Thouless equations, which we analyze within two models: an array of identical wires and a two-channel model with distinct channels. We show that a competition between disorder and interaction results in a variety of phases, expected to be observable at intermediate temperatures where the interaction and disorder are relevant but weak hybridization and the charge-density wave interaction may be ignored.

description: Cerium is a fascinating element due to its diverse physical properties, which include forming various crystal structures ($γ$, $α$, $α^{'}$, $α^{''}$ and $ε$), mixed valence behavior and superconductivity, making it an ideal platform for investigating the interplay between different electronic states. Here, we present a comprehensive transport study of cerium under hydrostatic pressures up to 54 GPa. Upon applying pressure, cerium undergoes the $α$ $\rightarrow$ $α^{''}$ transition at around 4.9 GPa, which is accompanied by the appearance of superconductivity with $T_{\rm c}$ of 0.4 K, and $T_{\rm c}$ slightly increases to 0.5 K at 11.4 GPa. At 14.3 GPa, $T_{\rm c}$ suddenly increases when the $α^{''}$ phase transforms into the $ε$ phase, reaching a maximum value of 1.25 K at around 17.2 GPa. Upon further increasing the pressure, $T_{\rm c}$ monotonically decreases. Together with the results of previous studies, our findings suggest that the evolution of superconductivity in cerium is closely correlated with the multiple pressure-induced structural transitions and corresponding unusual electronic structures.

description: We derive the classical counterpart of a previously obtained quantum mechanical covariant ``continuitylike'' equation for the spin density, and present an intuitive picture for elucidating the non-conservation of the spin current. This reveals the equations of motion for a particle with spin under the Yang-Mills field (in certain semiconductors) as well as the Maxwell field, from which the condition for an infinite spin relaxation time is drawn out directly. As a concrete example, we discuss the procession of the spin orientation in spin Hall effect with the so called ReD field, which undergoes a circle with the frequency dependent on both the strength of the spin-orbit coupling and the initial velocity. The anti-commutation of the Pauli matrices is found to be crucial in simplifying the equations of motion in the view of quantum mechanism of the same topics.

Building the worlds fastest* CryoEM processing platform (*under $100K)
Creators: name: Andrade, Jason
Publisher: name: Zenodo
Year: 2023

description: Situation

Cryogenic Electron Microscopy (CryoEM) continues to generate truly vast amounts of data. These volumes continue to increase as the cameras get better and more microscopes are deployed

UOW identified that our data processing needs (and costs) were growing. A lot!

We needed to build a new infrastructure platform to allow our facility to continue to meet these increased needs and we needed to do this without the "luxury" of a Go8 university budget.

Task

Take the 5 years of lessons we have learned from processing CryoEM data across 3 generations of infrastructure. Lots of people do this work – what have we learned that lets us build a better, more efficient and hopefully a more effective platform?

Design and build something that will work "out of the box" and tuned to our main processing application but also deals with the environmental (cooling, power) limitations as well as building to a budget.

How can we do this in the simplest possible infrastructure footprint (No, you cannot have a cluster!)

Does this technology even exist yet?

Action

Our group worked with our chosen vendor and separately with Nvidia to come up with a design that we were confident would work

We will go through the details we focused on including:

-The specifics of what we needed for computing
-What were the other things we needed to prioritize
-How do we make this work within our environment

Result

UOW currently has the world's fastest CryoEM processing platform under $100k

description: The translation of a bubble under the action of an acoustic forcing finds applications in fields ranging from drug delivery to sonoluminesce. This phenomenon has been widely studied for cases where the amplitude of the forcing remains constant over time. However, in many practical applications, the duration of the forcing is not long enough for the bubble to attain a constant translational velocity, mainly due to the effect of the history force. Here, we develop a formulation, valid in the limit of very viscous flow and small-amplitude acoustic forcing, that allows us to describe the transient dynamics of bubbles driven by acoustic pulses consisting of a finite number of cycles. We also present an asymptotic solution to this theory for the case of a finite-duration sinusoidal pressure pulse. This solution takes into account both the history integral term and the transient period that the bubble needs to achieve steady radial oscillations, being the former dominant during most of the acceleration process. Moreover, by introducing some additional assumptions, we derive a simplified formula that describes fairly well the time evolution of the bubble velocity. Using this solution we show that the convergence to the steady translational velocity, given by the so-called Bjerknes force, occurs rather slowly, namely as $τ^{-1/2}$, which explains the slow convergence of the bubble velocity and stresses the importance of taking into account the history force.

description: We present mean angular diameters for two cepheid variables, alpha Ursae Minoris and zeta Geminorum, determined with the Navy Prototype Optical Interferometer (NPOI). We present linear radii for these cepheids and two additional cepheids, delta Cephei and eta Aquilae, previously observed at the NPOI. We find the limb-darkened angular diameter of alpha Ursae Minoris and of zeta Geminorum to be 3.28 +/- 0.02 and 1.55 +/- 0.09 milliarcseconds respectively. Using trigonometric parallaxes, we find the linear radii of alpha Ursae Minoris, zeta Geminorum, delta Cephei and eta Aquilae to be 46 (+/- 3), 60 (+25, -14), 45 (+8, -6), and 69 (+28, -15) Solar radii respectively. We compare the pulsation periods and linear radii of this sample of cepheids, which range in period from three to 11 days, to theoretical and empirical period-radius and period-radius-mass relations found in the literature. We find that the observed diameter of alpha Ursae Minoris is in excellent agreement with the predicted diameter as determined from both surface brightness techniques and theory only if alpha Ursae Minoris is a first overtone pulsator.

description: Deep Operator Networks are an increasingly popular paradigm for solving regression in infinite dimensions and hence solve families of PDEs in one shot. In this work, we aim to establish a first-of-its-kind data-dependent lowerbound on the size of DeepONets required for them to be able to reduce empirical error on noisy data. In particular, we show that for low training errors to be obtained on $n$ data points it is necessary that the common output dimension of the branch and the trunk net be scaling as $Ω\left ( \sqrt[\leftroot{-1}\uproot{-1}4]{n} \right )$.
 This inspires our experiments with DeepONets solving the advection-diffusion-reaction PDE, where we demonstrate the possibility that at a fixed model size, to leverage increase in this common output dimension and get monotonic lowering of training error, the size of the training data might necessarily need to scale at least quadratically with it.

Using the long-term light curves and spectroscopic data, we tried to classify the PMS objects in the field and to define the reasons for the observed brightness variations. Our main goal is to explore the known PMS stars and discover new, young, variable stars. The new variable PMS star 2MASS J21403576+6635000 exhibits unusual brightness variations for very short time intervals (few minutes or hours) with comparatively large amplitudes (Delta I = 2.65 mag).

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We find the exact matrix model description of two dimensional Yang-Mills theories on a cylinder or on a torus and with an arbitrary compact gauge group. This matrix model is the singlet sector of a $c =1$ matrix model where the matrix field is in the fundamental representation of the gauge group. We also prove that the basic constituents of the theory are Sutherland fermions in the zero coupling limit, and this leads to an interesting connection between two dimensional gauge theories and one dimensional integrable systems. In particular we derive for all the classical groups the exact grand canonical partition function of the free fermion system corresponding to a two dimensional gauge theory on a torus.

Clearing residual planetesimals by sweeping secular resonances in transitional disks: a lone-planet scenario for the wide gaps in debris disks around Vega and Fomalhaut

description: Extended gaps in the debris disks of both Vega and Fomalhaut have been observed. These structures have been attributed to tidal perturbations by multiple super-Jupiter gas giant planets. Within the current observational limits, however, no such massive planets have been detected. Here we propose a less stringent `lone-planet' scenario to account for the observed structure with a single eccentric gas giant and suggest that clearing of these wide gaps is induced by its sweeping secular resonance. During the depletion of the disk gas, the planet's secular resonance propagates inward and clears a wide gap over an extended region of the disk. Although some residual intermediate-size planetesimals may remain in the gap, their surface density is too low to either produce super-Earths or lead to sufficiently frequent disruptive collisions to generate any observable dusty signatures. The main advantage of this lone-planet sweeping-secular-resonance model over the previous multiple gas giant tidal truncation scenario is the relaxed requirement on the number of gas giants. The observationally inferred upper mass limit can also be satisfied provided the hypothetical planet has a significant eccentricity. A significant fraction of solar or more massive stars bear gas giant planets with significant eccentricities. If these planets acquired their present-day kinematic properties prior to the depletion of their natal disks, their sweeping secular resonance would effectively impede the retention of neighboring planets and planetesimals over a wide range of orbital semi-major axes.

description: Supply sales of Midsouth cooperatives grew at an annual rate of 43 percent from 1951 to 1983. This rate of growth was unequaled by supply cooperatives in any other region of the United States. Total cooperative sales of 300 member locals reached $1.1 billion in 1983. Supply sales in the five-State area averaged 13 percent of farm production expenditures in 1973 and 22 percent in 1983. Outside factors had only limited effect on cooperative growth. Regionals operated generally free of cooperative competition and serve member locals in a State area. Cooperative management practices and teamwork contributed most to faster growth: Regional managers, dedicated to serving farmers first, developed and coordinated teamwork between regional and local operations; local support and commitment encouraged cooperative employees to help each other help the farmer.

It is consistent with the underlying dynamical quantum transport description and is capable of overcoming limitations of the only other consistent approach [New J. Phys. 12, 013013 (2010)]. We illustrate viability of the generalized inside-outside method with numerical simulations for generic junction models.

description: Superconducting parametric amplifiers play a crucial role in the preparation and readout of quantum states at microwave frequencies, enabling high-fidelity measurements of superconducting qubits. Most existing implementations of these amplifiers rely on the nonlinearity from Josephson junctions, superconducting quantum interference devices or disordered superconductors. Additionally, frequency tunability arises typically from either flux or current biasing. In contrast, semiconductor-based parametric amplifiers are tunable by local electric fields, which impose a smaller thermal load on the cryogenic setup than current and flux biasing and lead to vanishing crosstalk to other on-chip quantum systems. In this work, we present a gate-tunable parametric amplifier that operates without Josephson junctions, utilizing a proximitized semiconducting nanowire. This design achieves near-quantum-limited performance, featuring more than 20 dB gain and a 30 MHz gain-bandwidth product. The absence of Josephson junctions allows for advantages, including substantial saturation powers of -120dBm, magnetic field compatibility up to 500 mT and frequency tunability over a range of 15 MHz. Our realization of a parametric amplifier supplements efforts towards gate-controlled superconducting electronics, further advancing the abilities for high-performing quantum measurements of semiconductor-based and superconducting quantum devices.

description: By means of magnetic susceptibility and specific heat measurements, x-ray and unpolarised neutron diffraction investigations on powder and single-crystal samples, simultaneous long-range antiferromagnetic Fe and Nd ordering in NdFe3(11BO3)4 with R 3 2 chemical structure has been found at temperatures below TN = 30.5(5) K down to 1.6 K. At temperatures down to 20 K to the propagation vector is khex = [0,0,3/2] and becomes slightly incommensurate at lower temperatures. Symmetry analysis yields magnetic spiral configurations with the magnetic moments oriented parallel to hexagonal basal plane according to the irreducible representations tau_3 in the commensurate case. This is in agreement with the easy directions of magnetisation perpendicular to the c-axis as determined by magnetic susceptibility measurements. At 1.6 K the magnetic Fe moment amounts to 4.9 muB close to the free ion moment of Fe3+. The magnetic Nd3+ moment saturates presumably due to crystal-field effects at 2.7 muB.

Macquarie University's Path to Excellence in Research Data Management
Creators: name: Dashtbani Moghari, Mahdieh
Publisher: name: Zenodo
Year: 2023

description: Introduction

Data governance is critical for research institutes to manage and safeguard data assets, ensuring data privacy, protection, transparency, retention, sharing, and meeting legislative expectations and funders' requirements. Macquarie University launched its research data management (RDM) framework in late 2021, comprising three key components: 1) official policy, procedure and guideline documents; 2) infrastructure; and 3) support, advice and training.

Discussion

The RDM policy establishes roles, responsibilities, and guidelines for managing research data, considering data sensitivity level to ensure appropriate data handling, storage and sharing. The RDM framework led to the development of RDM Online module and Data Management Plan (DMP) tool, promoting awareness, risk mitigation, and adherence to FAIR and CARE data principles. To support the framework, a new RDM team was established, providing guidance on data management best practices throughout the research life cycle, delivering training, tools, resources, contributing to policy and guidelines development, conducting risk assessment for various research platforms, and ensuring compliance with legal and ethical requirements.

Conclusion

Macquarie's RDM framework ensures effective data management, secure data practices, and long-term integrity and accessibility of research data. Although significant progress has been made in transforming the university's data management culture, we recognize that it is an ongoing process. Through collaboration with IT, Research Ethics and Integrity, Graduate Research Academy, and Library, we are committed to providing optimal support for researchers. By fostering a culture that emphasizes proper data management and handling, we aim to shape the next generation of research and cultivate a lasting impact on data practices.

The $η$ and $η'$ nuclear potentials are obtained in the local density approximation from the mass shift of these mesons in nuclear matter, which is calculated within the quark-meson coupling model. Our results show that the $η$ and $η'$ mesons are expected to form mesic nuclei with all the nuclei considered. However, the signal for the formation of the $η$- and $η'$-mesic nuclei may be difficult to identify experimentally due to possible large widths.

description: In this article we will discuss a few aspects of the spacetime description of matter and fields. In Section:1 we will discuss the completeness of real numbers in the context of an alternate definition of the straight line as a geometric continuum. According to this definition, points are not regarded as the basic constituents of a line segment and a line segment is considered to be a fundamental geometric object. This definition is in particular suitable to coordinatize different points on the straight line preserving the order properties of real numbers. Geometrically fundamental nature of line segments are required in physical theories like the string theory. We will discuss the cardinality of rational numbers in the later half of Section:1. We will first discuss what we do in an actual process of counting and define functions well-defined on the set of all positive integers. We will follow an alternate approach that depends on the Hausdorff topology of real numbers to demonstrate that the set of positive rationals can have a greater cardinality than the set of positive integers. This approach is more consistent with an actual act of counting. This article indicates that the axiom of choice can be a better technique to prove theorems that use second-countability. This is important for the metrization theorems and physics of spacetime. In Section:2 we will discuss an improved proof of the Poisson's equation. We will show that the self energy of a point charge can be zero in the potential approach to evaluate it. In Section:3 we will discuss a few aspects of the equivalence of the Schwarzschild coordinates and the Kruskal-Szekeres coordinates. In Section:4 we will make a few comments on general physics including the special theory of relativity and hydrodynamics.

Accretion disc coronae as magnetic reservoirs

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Most astrophysical sources powered by accretion onto a black hole, either of stellar mass or supermassive, when observed with hard X-rays show signs of a hot Comptonizing component in the flow, the so-called corona, with observed temperatures and optical depths lying in a narrow range (0.1 < τ< 1 and 1x10^9 K < T < 3x10^9 K). Here we argue that these facts constitute strong supporting evidence for a magnetically-dominated corona. We show that the inferred thermal energy content of the corona, in all black hole systems, is far too low to explain their observed hard X-ray luminosities, unless either the size of the corona is at least of the order of 10^3 Schwarzschild radii, or the corona itself is in fact a reservoir, where the energy is mainly stored in the form of a magnetic field generated by a sheared rotator (probably the accretion disc). We briefly outline the main reasons why the former possibility is to be discarded, and the latter preferred.

description: The “green industry” is often noted in discussions of the costs and benefits of environmental policy, and it has been characterized as a unique industry with substantial potential for employment growth, well-paying jobs, and export opportunities. In this paper, we examine the characteristics and recent economic performance of the green industry, using establishment-level data on environmental products manufacturers (EPMs) from the 1995 Survey of Environmental Products and Services, together with data from the Annual Survey of Manufactures and various Census of Manufactures. Results suggest that there are some differences between EPMs and their non-EPM counterparts in the same industry, in terms of employment, employee compensation, exports, and productivity. However, we do not find any evidence that EPMs performed any better than otherwise similar plants, in terms of survival, employment growth, wage growth, and export growth. Our findings offer a more complex and nuanced portrayal of the green industry than is typical, and we suggest that this industry may not be as exceptional as is sometimes maintained.
Study of Electromagnetic Properties of Light Baryons in the Hypercentral Approach
Creators: name: Ghalenovi, Zahra
Publisher: name: arXiv
Year: 2017
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Light flavour baryons are studied in a non-relativistic potential model with colour Coulomb plus linear confinement potential using a simple variational method. The ground-state masses and magnetic moments of the light baryons are computed using a spin- and isospin-dependent potential. We extend our scheme to predict the transition magnetic moments of $B_{(J^P={3/2}^+)} \rightarrow B_{(J^P={1/2}^+)}γ$ processes. We also compute the radiative decay widths and branching ratios of light baryons. A comparison of our results with those of other works and experimental data is also presented.

description: This talk discusses our work at the University of Auckland (UoA) to support the payload and science operations for the remote-sensing airborne mission Rongowai (te reo M?ori: rongo meaning to sense, wai meaning water) using the Nectar research cloud infrastructure.

 Rongowai is a collaboration between NASA, the New Zealand Space Agency, and Air New Zealand to fly a next-generation Global Navigation Satellite System Reflectometry (GNSS-R) receiver on a commercial aircraft to collect climate data. The payload collects reflection data from the surface of Aotearoa, used to measure soil moisture, inundation, flooding, and even coastal erosion.

 To support the mission the UoA is facilitating post-flight payload communication, the processing of unstructured binary data into Level-0 and higher science data products (L0+), data hosting, and payload health monitoring.

 The payload has been fully supported since first-flight in mid-September 2022 and has experienced several major payload and workflow code updates, in addition to an aircraft lightning strike! Rongowai currently produces a total of ~175GB of binary-through-to L1 products produced per month, with high-level products about to be made available to the public.

description: Transmission spectroscopy provides a window to study exoplanetary atmospheres, but that window is fogged by clouds and hazes. Clouds and haze introduce a degeneracy between the strength of gaseous absorption features and planetary physical parameters such as abundances. One way to break that degeneracy is via statistical studies. We collect all published HST/WFC3 transit spectra for 1.1-1.65 $μ$m water vapor absorption, and perform a statistical study on potential correlations between the water absorption feature and planetary parameters. We fit the observed spectra with a template calculated for each planet using the Exo-Transmit code. We express the magnitude of the water absorption in scale heights, thereby removing the known dependence on temperature, surface gravity, and mean molecular weight. We find that the absorption in scale heights has a positive baseline correlation with planetary equilibrium temperature; our hypothesis is that decreasing cloud condensation with increasing temperature is responsible for this baseline slope. However, the observed sample is also intrinsically degenerate in the sense that equilibrium temperature correlates with planetary mass. We compile the distribution of absorption in scale heights, and we find that this distribution is closer to log-normal than Gaussian. However, we also find that the distribution of equilibrium temperatures for the observed planets is similarly log-normal. This indicates that the absorption values are affected by observational bias, whereby observers have not yet targeted a sufficient sample of the hottest planets.

description: Understanding the mechanical properties of glasses remains elusive since the glass transition itself is not fully understood, even in well studied examples of glass formers in two dimensions. In this context we demonstrate here: (i) a direct evidence for a diverging length scale at the glass transition (ii) an identification of the glass transition with the disappearance of fluid-like regions and (iii) the appearance in the glass state of fluid-like regions when mechanical strain is applied. These fluid-like regions are associated with the onset of plasticity in the amorphous solid. The relaxation times which diverge upon the approach to the glass transition are related quantitatively.

description: From the green alga Cladophora sp. collected in Italy, the marine fungal strain A12 of Trichoderma citrinoviride was isolated, identified and characterized. LC-MS qTOF analysis was applied to perform a metabolic profile of the fungal culture. Chromatographic techniques and spectroscopic methods were used to isolate and characterize the major secondary metabolites produced by this strain in liquid culture. In particular, four known sorbicillinoids (trichodermanone C, spirosorbicillinol A, vertinolide and sorbicillin) were purified and identified, together with 2-phenylethanol and tyrosol. Moreover, metabolomic analysis allowed to detect small amounts of trichodimerol, rezishanone A, 2′,3′-dihydrosorbicillin and bisvertinol. For the first time a significant inhibitory effect on nitrite levels has been shown for trichodermanone C in lipopolysaccharide-stimulated J774A.1 macrophages.
