description: Fullerenes have been observed in several astronomical objects since the discovery of C$_{60}$ in the mid-infrared (mid-IR) spectrum of the planetary nebula (PN) Tc 1. It has been suggested that the carriers of the broad unidentified infrared (UIR) plateau features, such as the 9$-$13$μ$m emission feature (12$μ$m hereafter), may be related to the formation of fullerenes. In particular, their carriers have been suggested to be mixed aromatic or aliphatic hydrocarbons such as hydrogenated amorphous carbon (HAC-like hereafter) grains. For this study, we modeled the mid-IR emission of the C$_{60}$-PN Tc 1 with a photoionization code, including for the first time the laboratory optical constants ($n$ and $k$ indices) of HAC-like dust at 300 K. Interestingly, we find that the broad 12$μ$m plateau feature in Tc 1 is well reproduced by using a distribution of canonical HAC grains, while at the same time they provide an important fraction of the IR dust continuum emission and are consistent with the other UIR features observed (e.g., the broad 6$-$9$μ$m plateau feature). This finding suggests that HAC-like grains may be possible carriers of the 12$μ$m plateau feature, being likely related to the fullerene formation mechanism in PNe. More laboratory experiments, to obtain the optical constants of HAC-like dust with several structures or a composition at different physical conditions, are strongly encouraged -- that is, in order to extend this pilot study to more fullerene PNe, and to unveil the details of fullerene formation and of the potential carriers of the elusive UIR plateau features.

description: We present measurements of Josephson junctions containing three magnetic layers with noncolinear magnetizations. The junctions are of the form $S/F^{\prime}/N/F/N/F^{\prime \prime}/S$, where $S$ is superconducting Nb, $F^\prime$ is either a thin Ni or Permalloy layer with in-plane magnetization, $N$ is the normal metal Cu, $F$ is a synthetic antiferromagnet (SAF) with magnetization perpendicular to the plane, composed of Pd/Co multilayers on either side of a thin Ru spacer, and $F^{\prime \prime}$ is a thin Ni layer with in-plane magnetization. The supercurrent in these junctions decays more slowly as a function of the $F$-layer thickness than for similar spin-singlet junctions not containing the $F^\prime$ and $F^{\prime \prime}$ layers. The slower decay is the prime signature that the supercurrent in the central part of these junctions is carried by spin-triplet pairs. The junctions containing $F^{\prime}=$ Permalloy are suitable for future experiments where either the amplitude of the critical current or the ground-state phase difference across the junction is controlled by changing the relative orientations of the magnetizations of the $F^{\prime}$ and $F^{\prime \prime}$ layers.

description: Deep near-infrared images of a blank 2'x2' section of sky near the Galactic north pole taken by Subaru Telescope are presented. The total integration times of the J and K' bands are 12.1 hours and 9.7 hours, resulting in 5-sigma limiting magnitudes of 25.1 and 23.5 mag, respectively. The numbers of sources within these limiting magnitudes found with an automated detection procedure are 385 in the J band and 350 in K'. Based on photometric measurements of these sources, we present number count vs. magnitude relations, color vs. magnitude diagrams, size vs. color relationships, etc. The slope of the galaxy number count plotted against the AB magnitude scale is about 0.23 in the 22 to 26 AB magnitude range of both bands. The spatial number density of galaxies as well as the slopes in the faint-end region given by the Subaru Deep Field (SDF) survey is consistent with those given by HST-NICMOS surveys as expressed on the AB magnitude diagram. Several sources having very large J-K' color are found including a few K' objects without detection at J. In addition, a number of faint Galactic stars are also detected, most of which are assigned to M-subdwarfs, together with a few brown dwarf candidates.

description: The composition-dependent behavior of the Dzyaloshinskii-Moriya interaction (DMI), the spin-orbit torque (SOT), as well as anomalous and spin Hall conductivities of Mn$_{1-x}$Fe$_x$Ge alloys have been investigated by first-principles calculations using the relativistic multiple scattering Korringa-Kohn-Rostoker (KKR) formalism. The $D_{\rm xx}$ component of the DMI exhibits a strong dependence on the Fe concentration, changing sign at $x \approx 0.85$ in line with previous theoretical calculations as well as with experimental results demonstrating the change of spin helicity at $x \approx 0.8$. A corresponding behavior with a sign change at $x \approx 0.5$ is predicted also for the Fermi sea contribution to the SOT, as this is closely related to the DMI. In the case of anomalous and spin Hall effects it is shown that the calculated Fermi sea contributions are rather small and the composition-dependent behavior of these effects are determined mainly by the electronic states at the Fermi level. The spin-orbit-induced scattering mechanisms responsible for both these effects suggest a common origin of the minimum of the AHE and the sign change of the SHE conductivities.

description: The mitigation of material defects from additive manufacturing (AM) processes is critical to reliability in their fabricated parts and is enabled by modeling the complex relations between available build monitoring signals and final mechanical performance. To this end, the present study investigates a machine learning approach for predicting mechanical properties for Ti-6Al-4V fabricated through laser powder bed fusion (PBF-LB) AM using in situ photodiode processing signals. Samples were fabricated under different processing parameters, varying laser powers and scan speeds for the purpose of probing a wide range of microstructure and property variations. Photodiode data were collected during fabrication, later to be arranged in image format and extracted to information-dense vectors by the transferal of deep convolutional neural network (DCNN) structures and weights pre-trained on a large computer vision benchmark image database. The extracted features were then used to train and test a newly designed regression model for mechanical properties. Average cross-validation accuracies were found to be 98.7% (r2 value of 0.89) for the prediction of ultimate tensile strength, which ranged from 900 to 1150 MPa in the samples studied, and 93.1% (r2 value of 0.96) for the prediction of elongation to fracture, which ranged from 0 to 17%. Thus, with high accuracy and hardware accelerated inference speeds, we demonstrate that a transfer learning framework can be used to predict strength and ductility of metal AM components based on processing signals in PBF-LB, illustrating a potential route toward real-time closed-loop control and process optimization of PBF-LB in industrial applications.

Effect of discontinuity in threshold distribution on the critical behaviour of a random fiber bundle

description: The critical behaviour of a Random Fiber Bundle Model with mixed uniform distribution of threshold strengths and global load sharing rule is studied with a special emphasis on the nature of distribution of avalanches for different parameters of the distribution. The discontinuity in the threshold strength distribution of fibers non-trivially modifies the critical stress as well as puts a restriction on the allowed values of parameters for which the recursive dynamics approach holds good. The discontinuity leads to a non-universal behaviour in the avalanche size distribution for smaller values of avalanche size. We observe that apart from the mean field behaviour for larger avalanches, a new behaviour for smaller avalanche size is observed as a critical threshold distribution is approached. The phenomenological understanding of the above result is provided using the exact analytical result for the avalanche size distribution. Most interestingly,the prominence of non-universal behaviour in avalanche size distribution depends on the system parameters.

description: The stability of metal-free very massive stars ($Z$ = 0; $M = 120 - 500 \msol$) is analyzed and compared with metal-enriched stars. Such zero-metal stars are unstable to nuclear-powered radial pulsations on the main sequence, but the growth time scale for these instabilities is much longer than for their metal-rich counterparts. Since they stabilize quickly after evolving off the ZAMS, the pulsation may not have sufficient time to drive appreciable mass loss in Z = 0 stars. For reasonable assumptions regarding the efficiency of converting pulsational energy into mass loss, we find that, even for the larger masses considered, the star may die without losing a large fraction of its mass. We find a transition between the $ε$- and $κ$-mechanisms for pulsational instability at $Z\sim 2\E{-4} - 2\E{-3}$. For the most metal-rich stars, the $κ$-mechanism yields much shorter $e$-folding times, indicating the presence of a strong instability. We thus stress the fundamental difference of the stability and late stages of evolution between very massive stars born in the early universe and those that might be born today.

description: We study the time dependent polariton condensation as well as the parametric scattering process of polaritons in a semiconductor microcavity. Based upon a new stochastic scheme the dynamics for both cases is fully analyzed. We show how the evolution of the system is described by a set of stochastic differential Schrodinger equations which in average reproduces the exact dynamics. Furthermore, we underline the role that Coulomb correlations plays in the polariton dynamics. Threshold behaviors are well captured by the present approach. The results are in complete agreement with recent experimental observations.

description: Find the training you need. Fast.

At the heart of good research is a highly skilled research workforce. But who doesn't struggle to find the training they need?

Digital Research Skills Australasia (DReSA) [https://dresa.org.au] is an online and freely accessible registry that describes and links to digital research training events, materials and trainers. It's a training community initiative born out of the need to improve the discoverability of training to upskill the research workforce on digital research methods and technologies. DReSA launched at eRA21.

More providers, more content, one location.

A key driver for the development of DReSA was to provide a comprehensive view of the research sector's digital research skills training. We have twenty-four providers already listed in DReSA. To be effective and sustainable, we need more providers sharing their training in DReSA. Our lightning presentation will demonstrate how easy it is for providers to register and start contributing content.

How easy is it, you ask?

It's pretty straightforward. Learn how to log in, register a provider account, provide approved editors, edit and delete accounts. We'll also share the current ingestion tools and provide information on the simple to set-up automated upload methods.

Add your organisation's name to the growing list of DReSA providers.

If what you hear and see piques your interest, we'll be around after the talk to answer questions and get you and your organisation started on your DReSA journey.
Parallel Approximate Maximum Flows in Near-Linear Work and Polylogarithmic Depth

description: We present a parallel algorithm for the $(1-ε)$-approximate maximum flow problem in capacitated, undirected graphs with $n$ vertices and $m$ edges, achieving $O(ε^{-3}\text{polylog} n)$ depth and $O(m ε^{-3} \text{polylog} n)$ work in the PRAM model. Although near-linear time sequential algorithms for this problem have been known for almost a decade, no parallel algorithms that simultaneously achieved polylogarithmic depth and near-linear work were known.
 At the heart of our result is a polylogarithmic depth, near-linear work recursive algorithm for computing congestion approximators. Our algorithm involves a recursive step to obtain a low-quality congestion approximator followed by a "boosting" step to improve its quality which prevents a multiplicative blow-up in error. Similar to Peng [SODA'16], our boosting step builds upon the hierarchical decomposition scheme of Räcke, Shah, and Täubig [SODA'14].
 A direct implementation of this approach, however, leads only to an algorithm with $n^{o(1)}$ depth and $m^{1+o(1)}$ work. To get around this, we introduce a new hierarchical decomposition scheme, in which we only need to solve maximum flows on subgraphs obtained by contracting vertices, as opposed to vertex-induced subgraphs used in Räcke, Shah, and Täubig [SODA'14]. In particular, we are able to directly extract congestion approximators for the subgraphs from a congestion approximator for the entire graph, thereby avoiding additional recursion on those subgraphs. Along the way, we also develop a parallel flow-decomposition algorithm that is crucial to achieving polylogarithmic depth and may be of independent interest.

description: We construct a correlation matrix based financial network for a set of New York Stock Exchange (NYSE) traded stocks with stocks corresponding to nodes and the links between them added one after the other, according to the strength of the correlation between the nodes. The eigenvalue spectrum of the correlation matrix reflects the structure of the market, which also shows in the cluster structure of the emergent network. The stronger and more compact a cluster is, the earlier the eigenvalue representing the corresponding business sector occurs in the spectrum. On the other hand, if groups of stocks belonging to a given business sector are considered as a fully connected subgraph of the final network, their intensity and coherence can be monitored as a function of time. This approach indicates to what extent the business sector classifications are visible in market prices, which in turn enables us to gauge the extent of group-behaviour exhibited by stocks belonging to a given business sector.

description: We present a new mapping algorithm, the "Accretion Stream Mapping (ASM)" which uses the full phase-coverage of a light curve to derive spatially resolved intensity distributions along the accretion stream in magnetic cataclysmic variables of AM Herculis type (polars). The surface of the accretion stream is approximated as a duodecadon shaped tube. After successfully testing this method on artificial data we applied it to emission line light curves of Hbeta, Hgamma and He II lambda 4686 of the bright eclipsing polar HU Aqr. We find Hydrogen and Helium line emission bright in the threading region of the stream where the stream couples onto magnetic field lines. It is particularly interesting, that the stream is bright on the irradiated side, facing the white dwarf, which highlights the interplay of collisional and radiative excitation/ionization.

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: In disordered elastic systems, driven by displacing a parabolic confining potential adiabatically slowly, all advance of the system is in bursts, termed avalanches. Avalanches have a finite extension in time, which is much smaller than the waiting-time between them. Avalanches also have a finite extension $\ell$ in space, i.e. only a part of the interface of size $\ell$ moves during an avalanche. Here we study their spatial shape $\left< S(x)\right>_{\ell}$ given $\ell$, as well as its fluctuations encoded in the second cumulant $\left< S^{2}(x)\right>_{\ell}^{\rm c}$. We establish scaling relations governing the behavior close to the boundary. We then give analytic results for the Brownian force model, in which the microscopic disorder for each degree of freedom is a random walk. Finally, we confirm these results with numerical simulations. To do this properly we elucidate the influence of discretization effects, which also confirms the assumptions entering into the scaling ansatz. This allows us to reach the scaling limit already for avalanches of moderate size. We find excellent agreement for the universal shape, its fluctuations, including all amplitudes.

description: The Fast Handover for MIPv6 protocol (FMIPv6) [1] provides seamlesshandover in wireless IPv6 networks by minimizing handover latency. Toreduce handover latency and to provide faster handover, Fast Handoveruses anticipation based on layer 2 (L2) trigger information. Therefore, itincurs higher signaling costs compared with the Mobile IPv6 protocol.Furthermore, since the L2 trigger is based on fluctuating wireless channelstates, the handover anticipation using the L2 trigger may sometimes beincorrect. In the case of incorrect anticipation, unnecessary buffer spacemay be used for the purpose of providing a smooth handover.In this paper, an enhanced FMIPv6 scheme for Mobile IPv6 hasproposed. In this scheme, each AR (Access Router) maintains a CoA(Care of Address) table and generates the new CoA from NAR then itpass this nCoA to the MN that will move to its domain through PAR.Also, the binding updates to home agent and correspondent node are to beperformed from the time point when the PAR sends FBack to MN andNAR simultaneously. The impact of the L2 triggering time on the totaloverhead cost has studied and formulated these costs based on a timingdiagram and compared proposed scheme with existing FMIPv6.As a result, the L2 triggering time is an important factor to consider in theoptimization of handover performance and the proposed schemegenerates more signal cost comparing with existing FMIPv6 but on theother hand, less overhead comparing with existing FMIPv6 protocol atall.

description: We consider the initialization of the spin-state of a single electron trapped in a self-assembled quantum dot via optical pumping of a trion level. We show that with a magnetic field applied perpendicular to the growth direction of the dot, a near-unity fidelity can be obtained in a time equal to a few times the inverse of the spin-conserving trion relaxation rate. This method is several orders-of-magnitude faster than with the field aligned parallel, since this configuration must rely on a slow hole spin-flip mechanism. This increase in speed does result in a limit on the maximum obtainable fidelity, but we show that for InAs dots, the error is very small.

description: Persistent Identifiers (PIDs) are a core component of a world class, global digital information ecosystem as they provide a universal, machine-readable method to uniquely identify and connect entities within the ecosystem.

The September 2022 report, commissioned by ARDC and AAF, Incentives to invest in identifiers: a cost-benefit analysis of persistent identifiers in Australian research systems, found potential savings to the Australian research system of $24 million and 38, 000 person days per year through use of persistent identifiers (PIDs).  If these savings are re-applied back into research and development this would result in $84 million annual economy-wide benefits for Australia (CSIRO Working Paper).

To realise these anticipated benefits requires a coordinated, comprehensive and collaborative approach to PIDs, bringing together the key stakeholders across the national research, innovation and impact ecosystem. In collaboration with AAF, the ARDC's approach is therefore to convene a broad and open national discussion that will result in a widely understood national PID strategy and an accompanying roadmap. The National PID Strategy and Roadmap are not binding top-down policies. They are rather a stakeholder-driven vision of a future research system optimised through use of PIDs. They seek to provide a shared framework to inform co-investment and policy development by relevant organisations.

This BOF will form part of this national conversation to create shared value and a shared commitment to action.  Drafts of the Strategy and Roadmap will be available prior to the BOF.

description: We conducted multi-epoch VLBA phase reference observations of LS I +61 303 in order to study its precessing radio jet. Compared to similar observations in 2006, we find that the observed elliptical trajectory of emission at 8.4 GHz repeats after the 9-year gap. The accurate alignment of the emission patterns yields a precession period of 26.926 +- 0.005 d, which is consistent with that determined by Lomb-Scargle analysis of the radio light curve. We analytically model the projection on the sky plane of the peak position of a precessing, synchrotron-emitting jet, which traces an elliptical trajectory on the sky. Comparing the simulation with the VLBA astrometry we improve our knowledge of the geometry of the system.We measure the LS I +61 303 absolute proper motion to be -0.150 +- 0.006 mas/yr eastward and -0.264 +- 0.006 mas/yr northward. Removing Galactic rotation, this reveals a small, < 20 km/s, non-circular motion, which indicates a very low kick velocity when the black hole was formed.

description: It was suggested that two entangled fermions can behave like a single boson and that the bosonic quality is proportional to the degree of entanglement between the two particles. The relation between bosonic quality and entanglement is quite natural if one takes into account the fact that entanglement appears in bound states of interacting systems. However, entanglement can still be present in spatially separated subsystems that do not interact anymore. These systems are often a subject of studies on quantum nonlocality and foundations of quantum physics. Here, we ask whether an entangled spatially separated fermionic pair can exhibit bosonic properties. We show that in certain conditions the answer to this question can be positive. In particular, we propose a nonlocal bunching scenario in which two such pairs form an analogue of a two-partite bosonic Fock state.

description: We introduce a novel method for measuring properties of periodic phenomena with an event camera, a device asynchronously reporting brightness changes at independently operating pixels. The approach assumes that for fast periodic phenomena, in any spatial window where it occurs, a very similar set of events is generated at the time difference corresponding to the frequency of the motion. To estimate the frequency, we compute correlations of spatio-temporal windows in the event space. The period is calculated from the time differences between the peaks of the correlation responses. The method is contactless, eliminating the need for markers, and does not need distinguishable landmarks. We evaluate the proposed method on three instances of periodic phenomena: (i) light flashes, (ii) vibration, and (iii) rotational speed. In all experiments, our method achieves a relative error lower than 0.04%, which is within the error margin of ground truth measurements.

DReSA - a story of continuing collaboration in skills training
Creators: name: Burke, Melissa
Publisher: name: Zenodo
Year: 2023

description: Collaboration: multiplying talent, dividing effort

Collaboration is a valuable approach for leveraging collective knowledge, skills, and resources to achieve common goals that may be impossible to accomplish individually.

This presentation provides perspectives on the importance of collaboration for successfully developing skills training infrastructure, namely the Digital Research Skills Australasia training registry (DReSA).

What is DReSA?

DReSA is an online and freely accessible registry that describes and links to digital research training events, materials and trainers. It's a training community initiative born out of the need to improve the discoverability of training to upskill the research workforce on digital research methods and technologies.

Collaboration: from idea to functioning registry to sustainable future

This presentation will take you on a journey of collaboration.
From:
- A common idea that came out of ARDC Skills Summits and - --trainer forums
- A working group to scope the idea and its challenges
- Leveraging connections between the Australian BioCommons and ELIXIR's training portal TeSS
- Investments from Pawsey and ARDC to support the development of a fully functioning training registry

To:
- A partnership between the ARDC, NCI and Pawsey to ensure DReSA's longevity.
- Continuing support from the wider community, and the grassroots effort that spearheaded and built today's DReSA

Ultimately, DReSA is a story of community and highlights the importance of grassroots support and trusted partnerships for enhancing the longevity, development, outreach, and maintenance of DReSA. An exemplar for other projects.

Untwisting of a Strained Cholesteric Elastomer by Disclination Loop Nucleation

description: The application of a sufficiently strong strain perpendicular to the pitch axis of a monodomain cholesteric elastomer unwinds the cholesteric helix. Previous theoretical analyses of this transition ignored the effects of Frank elasticity which we include here. We find that the strain needed to unwind the helix is reduced because of the Frank penalty and the cholesteric state becomes metastable above the transition. We consider in detail a previously proposed mechanism by which the topologically stable helical texture is removed in the metastable state, namely by the nucleation of twist disclination loops in the plane perpendicular to the pitch axis. We present an approximate calculation of the barrier energy for this nucleation process which neglects possible spatial variation of the strain fields in the elastomer, as well as a more accurate calculation based on a finite element modeling of the elastomer.

description: Starting from a Skyrme interaction with tensor terms, the $β$-decay rates of $^{52}$Ca have been studied within a microscopic model including the $2p-2h$ configuration effects. We observe a redistribution of the strength of Gamow-Teller transitions due to the $2p-2h$ fragmentation. Taking into account this effect results in a satisfactory description of the neutron emission probability of the $β$-decay in $^{52}$Ca.

description: Loop equations of matrix models express the invariance of the models under field redefinitions. We use loop equations to prove that it is possible to define continuum times for the generic hermitian {1-matrix} model such that all correlation functions in the double scaling limit agree with the corresponding correlation functions of the Kontsevich model expressed in terms of kdV times. In addition the double scaling limit of the partition function of the hermitian matrix model agree with the $τ$-function of the kdV hierarchy corresponding to the Kontsevich model (and not the square of the $τ$-function) except for some complications at genus zero.
