description: In this paper, we propose to estimate the spatial curvature of the universe and the cosmic opacity in a model-independent way with expansion rate measurements, $H(z)$, and type Ia supernova (SNe Ia). On the one hand, using a nonparametric smoothing method Gaussian process, we reconstruct a function $H(z)$ from opacity-free expansion rate measurements. Then, we integrate the $H(z)$ to obtain distance modulus $μ_{\rm H}$, which is dependent on the cosmic curvature. On the other hand, distances of SNe Ia can be determined by their photometric observations and thus are opacity-dependent. In our analysis, by confronting distance moduli $μ_{\rm H}$ with those obtained from SNe Ia, we achieve estimations for both the spatial curvature and the cosmic opacity without any assumptions for the cosmological model. Here, it should be noted that light curve fitting parameters, accounting for the distance estimation of SNe Ia, are determined in a global fit together with the cosmic opacity and spatial curvature to get rid of the dependence of these parameters on cosmology. In addition, we also investigate whether the inclusion of different priors for the present expansion rate ($H_0$: global estimation, $67.74\pm 0.46~\rm km~ s^{-1} ~Mpc^{-1}$, and local measurement, $73.24\pm 1.74~\rm km~ s^{-1} ~Mpc^{-1}$) exert influence on the reconstructed $H(z)$ and the following estimations of the spatial curvature and cosmic opacity. Results show that, in general, a spatially flat and transparent universe is preferred by the observations. Moreover, it is suggested that priors for $H_0$ matter a lot. Finally, we find that there is a strong degeneracy between the curvature and the opacity.

description: We use the hot spot eclipse times of the newly discovered deeply-eclipsing dwarf nova IY UMa to trace out the shape of its disc during the late superhump era. We find an eccentric disc. We show that the brightness of the stream-disc impact region varies as expected with |deltaV|^2, where deltaV is the differential velocity of the stream with respect to the velocity of the disc at the impact point. We conclude that the hot spot is the source of late superhump light.

description: Careful examination of communicative outcomes of mHealth technology is critical for understanding its capacity to shape the clinical interview and structure clinic communication. Drawing on a communicative affordances framework and adopting a video-based inductive analytic approach, we extend the concept of actualizations. We do so by examining the in situ communicative actions afforded by a mHealth web interface utilized during medication titration interviews with parents of children beginning stimulant medication for ADHD. We find that the web interface served five broad communicative functions that provided opportunities for improving information accuracy and for rendering clinical reasoning transparent, while jeopardizing opportunities for parents to narrativize medication experiences. We discuss clinical, theoretical, and methodological implications.

description: Recent years have seen many examples of how the strong spin-orbit coupling (SOC) present in iridates can stabilize new emergent states that are difficult or impossible to realize in more conventional materials. In this review we outline a representative set of studies detailing how heterostructures based on Ruddlesden-Popper (RP) and perovskite iridates can be used to access yet more novel physics. Beginning with a short synopsis of iridate thin film growth, the effects of the heterostructure morphology on the RP iridates including Sr2IrO4 and SrIrO3 are discussed. Example studies explore the effects of epitaxial strain, laser-excitation to access transient states, topological semimetallicity in SrIrO3, 2D magnetism in artificial RP iridates, and interfacial magnetic coupling between iridate and neighboring layers. Taken together, these works show the fantastic potential for controlled engineering of novel quantum phenomena in iridate heterostructures.

title: Measurement and Stochastic Computational Modeling of the Elastic Properties of Parallel Strand Lumber
Creators: name: Arwade,

Publisher: name: University of Massachusetts Amherst
Year: 2009

description: This paper describes a model for the spatial variation of the elastic modulus of parallel strand lumber (PSL) that is based on bending experiments and also describes a validated stochastic computational model that incorporates orthotropic elasticity and uncertainty in strand geometry and material properties. The PSL exhibits significant variability both within members and between members, but this variability is less than that of equivalent sawn-wood members, and decreases with increasing member size. The correlation length of the elastic modulus is found to be several meters and is independent of the cross-sectional size. The variance of PSL elastic modulus is found to scale inversely with the number of strands in the cross section. The validated computational model is flexible enough to allow preliminary exploration of the properties of new mixes of species and strand sizes in PSL material design.

A blueprint for a systemwide approach to Trust and Identity
Creators: name: Rossow, Nick
Publisher: name: Zenodo

Subjects: Trust and Identity
Access and Authorisation

description: Identity and access management has always been a critical component of digital research infrastructure. In modern research infrastructure, there is a need for it to be more than just a username, password and access controls. In 2019, the Australian Access Federation (AAF) developed Making the Case - a proposal to elevate identity and access management into trust and identity (T&I).

T&I is more than giving a digital identity permission to access a digital resource. It  builds and manages trusted relationships between users and research infrastructures. It is fundamental infrastructure that will create significant advances for Australian researchers. AAF in partnership with fellow NCRIS facilities, are collaboratively building a T&I Framework that includes common policies, standards and technologies, enabling researchers to enjoy a more cohesive network of services. The goal of the project is to create a standard approach to T&I across the NCRIS system.

AAF are partnering with the NCRIS community to pilot and implement a T&I Framework which has been successfully adopted internationally by large research communities such as the:
* Worldwide Large Hadron Collider Computing Grid
* The Cherenkov Telescope Array
* European Life Science Research Infrastructures.

This presentation will show how the AAF and NCRIS facilities are taking a system-wide approach to T&I, and how this will improve connectivity across the research infrastructure ecosystem. We will also show how the T&I Framework is enhancing the cyber security of NCRIS and powering global connectivity.

Rigorous approach to the nonlinear saturation of the tearing mode in cylindrical and slab geometry

description: The saturation of the tearing mode instability is described within the standard framework of reduced magnetohydrodynamics (RMHD) in the case of an $r$-dependent or of a uniform resistivity profile. Using the technique of matched asymptotic expansions, where the perturbation parameter is the island width $w$, the problem can be solved in two ways: with the so-called flux coordinate method, which is based on the fact that the current profile is a flux function, and with a new perturbative method that does not use this property. The latter is applicable to more general situations where an external forcing or a sheared velocity profile are involved. The calculation provides a new relationship between the saturated island width and the $Δ'$ stability parameter that involves a $\ln{w/w_{0}}$ term, where $w_{0}$ is a nonlinear scaling length that was missing in previous work. It also yields the modification of the equilibrium magnetic flux function.

description: We study the stable rationality problem for quadric and cubic surface bundles over surfaces from the point of view of the degeneration method for the Chow group of 0-cycles. Our main result is that a very general hypersurface X of bidegree (2,3) in P^2 x P^3 is not stably rational. Via projections onto the two factors, X is a cubic surface bundle over P^2 and a conic bundle over P^3, and we analyze the stable rationality problem from both these points of view. This provides another example of a smooth family of rationally connected fourfolds with rational and nonrational fibers. Finally, we introduce new quadric surface bundle fourfolds over P^2 with discriminant curve of any even degree at least 8, having nontrivial unramified Brauer group and admitting a universally CH_0-trivial resolution.

We categorify the left and right symmetric group actions on these exceptional sequences to two braid group actions: of spherical twists along simple modules, and of right mutations. In particular, every such exceptional sequence is obtained by spherical twists from a standard sequence, and likewise for right mutations.

description: The realization of single-photon generation is important for implementing various quantum information technologies. The use of rare-earth ions in an optical fiber is a promising single photon generation method due to its ability to operate at room temperature as well as the low cost involved. Neodymium ions are especially interesting because the ions are one of the most commercially affordable rare-earth materials in the current industry. The neodymium ion also has the advantage of having a rich energy level structure, which offers several possible wavelengths for emitted single photons from visible to near-telecommunication wavelengths. In this paper, we experimentally demonstrated single-photon generation using an isolated single neodymium ion in tapered silica fiber at room temperature. Our results have significant implications as a platform for low-cost wavelength-selectable single-photon sources and photonic quantum applications.

Critical Rotational Frequency for Superfluid Fermionic Gases across a Feshbach Resonance

description: We present a method to determine the critical rotational frequencies for superfluidity of both uniform and trapped Fermi gases across wide Feshbach resonance. It is found that as one approaches the resonance from the BCS side, beyond a critical scattering length, pairing is so robust that superfluidity cannot be destroyed by rotation. Moreover, the critical frequency has a sequence of jumps revealing the appearance of Landau levels, which are particularly prominent for systems up to a few thousand particles. For rotational frequency below an "ultimate" critical frequency, defined to be the lowest frequency at which the center of the cloud goes normal, a trapped gas has a superfluid core surrounded by a normal gas, as seen in recent experiments.

Year: 2023

description: The National Collaborative Research Infrastructure Strategy (NCRIS) funds the Australian Urban Research Infrastructure Network (AURIN) to provide national research infrastructure which plays a key role in supporting Australia's response to the rising challenges of climate change, energy transition, and demographic change. AURIN facilitates this through the Urban Data as a Service (UDaaS) platform which aims to seamlessly empower researchers and Urban Digital Twin (UDT) efforts across Australia with high-value data to inform planning, policy and decision making.

The UDaaS platform provides users with data that is curated and standardised to reduce the costs of transactions for the development and management of the UDTs. AURIN utilises and continues to develop an Extract, Transform and Load (ETL) data pipeline focusing on enabling the creation of data products in a reproducible, atomic, automated, and flexible manner. Distributed infrastructure acts as the basis to allow for the flexibility and scalability of the data pipelines; and Directed Acyclic Graphs (DAGs) provide control for actions made to the data. The AURIN ETL pipeline allows ingestion, curation, and delivery of data from any data provider to any data consumer in a robust and streamlined way. It is designed flexible enough to seamlessly incorporate new and emerging data formats, empowering users to harness the full potential of data from various sources in their analyses and applications.

AURIN's commitment to innovative technologies and streamlined processes makes it a crucial resource for urban research and evidence-based decision-making to tackle critical urban challenges.

An Empirical Procedure to Estimate Distances to Stellar Clusters

Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A most desirable feature of a standard candle to estimate astronomical distances is robustness against changes in metallicity and age. It is argued that the radii of main sequence stars with spectral types from solar to A0 show predictable changes with metallicity, and detectable changes with evolution. Such stars populate the solar neighborhood, and therefore benefit from measurements of angular diameters. Also, reliable determinations of their masses and radii are available from observations of eclipsing binaries. Three empirical relationships are defined and suggested for estimating distances to dwarfs from only BVK photometry. Comparison with HIPPARCOS trigonometric parallaxes shows that the method provides errors of about 15% for a particular star, which can be reduced to roughly 1.5% when applied to young clusters (age

description: Opportunities for U.S. cooperatives to trade grains, oilseeds, and products with Czechoslovakia, the German Democratic Republic (G.DR), Hungary, and Poland are evaluated and marketing alternatives discussed. U.S. agricultural exports to these four countries totaled $497 million in 1982, representing 2.4 percent of total U.S. agricultural exports. Poland was the largest customer, followed by GDR, Czechoslovakia, and Hungary. Despite increased efforts toward self-sufficiency in grain and oilseed production, Eastern European countries are expected to remain substantial net importers in the 1980’s. Net imports of the four countries are projected to reach 6.3 million tons of feedgrains, 2.8 million tons of wheat, and 3.8 million tons of oilseed products in 1985. By 1990, net imports are projected to increase slightly to 6.4 million tons of oilseeds and products. Imports in these countries are arranged through Foreign Trade Organizations (FTO’s). Doing business with these state-owned monopolies requires special marketing skills and considerations. The FTO’s prefer to deal with suppliers that can provide desired commodities, quantities, qualities, and related services and can assure performance according to agreed terms. FTO’s tend to buy from the lowest bidder. Buyers preferred to deal with European-based sellers to facilitate communications and other relationships. To date, counter trade requests tied to grains and oilseeds imports are infrequent. Increasing hard currency balance of payments problems may increase the frequency of such requests. Credit terms are essential in making sales to some countries. Recent repayment difficulties, however, suggest caution in extending credit.

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks

Subjects: subject: Geophysics (physics.geo-ph)

description: We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging electric battery under increasing stress. The electric charges are released by activation of dormant charge carriers in the oxygen anion sublattice, called peroxy bonds or positive hole pairs (PHP), where a PHP represents an $O_3X/^{OO}\backslash YO_3$ with $X,Y = Si^{4+}, Al^{3+}...$, i.e. an $O^-$ in a matrix of $O^{2-}$ of silicates. We propose that PHP are activated by plastic deformations during the slow cooperative build-up of stress and the increasingly correlated damage culminating in a large ``critical'' earthquake. Recent laboratory experiments indeed show that stressed rocks form electric batteries which can release their charge when a conducting path closes the equivalent electric circuit. We conjecture that the intermittent and erratic occurrences of EM signals are a consequence of the progressive build-up of the battery charges in the Earth crust and their erratic release when crack networks are percolating throughout the stressed rock volumes, providing a conductive pathway for the battery currents to discharge. EM signals are thus expected close to the rupture, either slightly before or after, that is, when percolation is most favored.

description: Around a million quasars have been catalogued in the Universe by probing deeper and using new methods for discovery. However, the hardest ones to find seem to be the rarest and brightest specimen. In this work, we study the properties of the most luminous of all quasars found so far. It has been overlooked until recently, which demonstrates that modern all-sky surveys have much to reveal. The black hole in this quasar accretes around one solar mass per day onto an existing mass of $\sim$17 billion solar masses. In this process its accretion disc alone releases a radiative energy of $2\times 10^{41}$ Watts. If the quasar is not strongly gravitationally lensed, then its broad line region (BLR) is expected to have the largest physical and angular diameter occurring in the Universe, and will allow the Very Large Telescope Interferometer to image its rotation and measure its black hole mass directly. This will be an important test for BLR size-luminosity relations, whose extrapolation has underpinned common black-hole mass estimates at high redshift.

description: The subjects of this article are the life and spirituality of Genoese Carmelite nun Maria Agnese Pinceti (born Francesca Pinceti 1693 - 1761). After discussing the origins of Genoa’s Carmel between the sixteenth and seventeenth century, the article will focus on the papers that informed us on Pinceti’s life. In specific, the article focuses on Pinceti’s life – narrated in a manuscript preserved at the Carmelitan monastery in Genoa – as well as on the letters she received from the Augustinian father Carlo Giacinto di Santa Maria (1658 - 1721). Both Carmelitan and Genoese spirituality of that era emerge as key subjects of the manuscript, with themes including the Marian devotion, the cult of relics, the craftsmanship inside the convent and the multiple forms of prayers.

description: We obtain the exact Dirac algebra obeyed by the conserved non-local charges in bosonic non-linear sigma models. Part of the computation is specialized for a symmetry group $O(N)$. As it turns out the algebra corresponds to a cubic deformation of the Kac-Moody algebra. The non-linear terms are computed in closed form. In each Dirac bracket we only find highest order terms (as explained in the paper), defining a saturated algebra. We generalize the results for the presence of a Wess-Zumino term. The algebra is very similar to the previous one, containing now a calculable correction of order one unit lower.

description: Data from the first three years of RXTE observations have been systematically analyzed to yield a set of 300 day, 2-10 keV light curves with similarly uniform, ~5 day sampling, for a total of nine Seyfert 1 galaxies. This is the first X-ray variability survey to consistently probe time scales longer than a few days in a large number of AGN. Comparison with ASCA data covering a similar band but much shorter (~1 day) time scales shows that all the AGN are more strongly variable on long time scales than on short time scales. This increase is greatest for the highest-luminosity sources. The well-known anticorrelation between source luminosity and variability amplitude is both stronger and shallower in power-law slope when measured on long time scales. This is consistent with a picture in which the X-ray variability of Seyfert 1s can be can be described by a single, universal fluctuation power density shape for which the cutoff moves to longer time scales for higher luminosity sources. All of the Seyfert 1s exhibit stronger variability in the relatively soft 2-4 keV band than in the harder 7-10 keV band. This effect is much too pronounced to be explained by simple models based on either the dilution of the power-law continuum by the Compton reflection component or on the hard X-rays being produced in a static, pair-dominated, plane-parallel Comptonizing corona.

description: We study the quantum phase transition from an antiferromagnetic metal to a heavy fermion metal in the Kondo lattice model. Based on the strong coupling approach we {\it first} diagonalize the Kondo coupling term. Since this strong coupling approach makes the resulting Kondo term {\it relevant}, the Kondo hybridization persists even in the antiferromagnetic metal, indicating that fluctuations of Kondo singlets are not critical in the phase transition. We find that the quantum transition in our strong coupling approach results from {\it softening of antiferromagnetic spin fluctuations of localized spins}, driven by the Kondo interaction. Thus, the volume change of Fermi surface becomes continuous across the transition. ......
Data governance for responsible research
Creators: name: Brown, Dianne
Publisher: name: Zenodo
Year: 2023

description: Responsible research is one of the three research principles at Monash University and Research Data Governance is one of the core areas for responsible conduct of research at Monash. Responsible management of research data requires significant investment of time, effort and resources from both institutions and researchers, but lack of clarity on institutional and researcher responsibilities leads to inconsistent data governance practices across the institution.

To address the inconsistencies, we developed a program to
1. Clearly articulate the roles and responsibilities of the institution and the individual researchers/Principal investigators
2. Develop a roadmap for addressing the capability gaps to perform the identified roles and responsibilities, which includes  policies, processes, people, technology and literacy.

Our approach was
1. The ARC/NHMRC's "The Australian Code for the Responsible Conduct of Research (2018)" and the supporting guidelines in their "Management of Data and Information In Research" have been used to outline the responsibilities of the institution and the researchers. This has then been overlaid with the emerging concepts from the broader Data Governance frameworks used in industry.
2. A Gap assessment of capabilities available at the institutional level has been conducted through surveys, interviews and consultations.
3. Tools, guidelines and literacy programs available for researchers has been evaluated

The gaps assessment has been used to develop a comprehensive program plan to address policies, guidelines, tools and literacy programs required to roll out consistent data governance practices across the institution. This has complemented the application process for the data user accreditation under the DATA scheme.

Nuovi documenti per Francesco Maria Schiaffino in San Siro a Genova-Nervi e per il patrimonio artistico della casaccia di Santa Maria di Caprafico

description: The discovery of unpublished documentation (in the Archivio di Stato di Genova and in the parish archives) on the chapel of the Crucifix in the parish church of San Siro in Genova-Nervi has enabled to attribute to the Genoese sculptor Francesco Maria Schiaffino the great marble structure of the altar and the statues in white marble (1753-1758) at the side of the polychrome wooden crucifix of the Maraglianesca school. In 1759 the confraternity of the 72 Disciples, patrons of the chapel, entrusted Giovanni Agostino Ratti with the task to paint the frescoes of the vault with the Resurrection of Christ and to the quadraturist Rocco Costa the architectural trompe-l’oeils on the walls. On the floor, in front of the chapel, the tombstone of the brothers is still visible. The confraternity was also part of the oratory of the ‘casaccia’ of Santa Maria di Caprafico di Nervi, known from the end of the fifteenth century when the sculptor Giovanni Gaggini had provided the marble balustrade of the presbytery (1495, no longer existing). The oratory, which preserves an altar in polychrome marble by Gaetano Gallo (1745-1748), in 1758 had an organ (no longer existing) made by the famous organist Tomaso Roccatagliata. In addition to the famous eighteenth-century statue of the Assumption in polychrome wood, the confraternity has a processional Crucifix (1762) by a pupil of Maragliano, with a cross decorated with silver figures dated 1823 with the turret punch, and a set of splendid eighteenth-century velvet tabarrini in crimson with gold and silver thread embroidery purchased in 1853 from the now destroyed Genoese oratory of San Giacomo delle Fucine.

description: Individuals with vision impairments employ a variety of strategies for object identification, such as pans or soy sauce, in the culinary process. In addition, they often rely on contextual details about objects, such as location, orientation, and current status, to autonomously execute cooking activities. To understand how people with vision impairments collect and use the contextual information of objects while cooking, we conducted a contextual inquiry study with 12 participants in their own kitchens. This research aims to analyze object interaction dynamics in culinary practices to enhance assistive vision technologies for visually impaired cooks. We outline eight different types of contextual information and the strategies that blind cooks currently use to access the information while preparing meals. Further, we discuss preferences for communicating contextual information about kitchen objects as well as considerations for the deployment of AI-powered assistive technologies.

description: Planning for hazard mitigation is frequently detached from other planning activities that influence development patterns in hazardous areas. Consistent integration of mitigation reduces hazard vulnerability for people and the built environment. We apply a plan integration for resilience scorecard in six US coastal cities to evaluate the integration of local networks of plans and the degree to which they target areas most vulnerable to flooding hazards. We find that plan integration scores vary widely across the six cities, and that some plans actually increase vulnerability in hazard zones. Policies also frequently support mitigation in areas with low vulnerability, rather than in areas with high vulnerability. The plan integration for resilience scorecard can generate information to improve hazard planning by allowing planners to identify conflicts between plans, assess whether plans target areas that are most vulnerable, and better inform decision makers about opportunities to mainstream mitigation into multiple sectors of planning.

description: High precision radial velocity (RV) measurements spanning the years 1980.8--2000.0 are presented for the nearby (3.22 pc) K2 V star $ε$ Eri. These data, which represent a combination of six independent data sets taken with four different telescopes, show convincing variations with a period of $\approx$ 7 yrs. A least squares orbital solution using robust estimation yields orbital parameters of period, $P$ = 6.9 yrs, velocity $K$-amplitude $=$ 19 {\ms}, eccentricity $e$ $=$ 0.6, projected companion mass $M$ sin $i$ = 0.86 $M_{Jupiter}$, and semi-major axis $a_2$ $=$ 3.3 AU. Ca II H&K S-index measurements spanning the same time interval show significant variations with periods of 3 and 20 yrs, yet none at the RV period. If magnetic activity were responsible for the RV variations then it produces a significantly different period than is seen in the Ca II data. Given the lack of Ca II variation with the same period as that found in the RV measurements, the long-lived and coherent nature of these variations, and the high eccentricity of the implied orbit, Keplerian motion due to a planetary companion seems to be the most likely explanation for the observed RV variations. The wide angular separation of the planet from the star (approximately 1 arc-second) and the long orbital period make this planet a prime candidate for both direct imaging and space-based astrometric measurements.

Dynamical analysis for a scalar-tensor model with kinetic and non-minimal couplings

description: We study the autonomous system for a scalar-tensor model of dark energy with non-minimal coupling to curvature and non-minimal kinetic coupling to the Einstein tensor. The critical points describe important stable asymptotic scenarios including quintessence, phantom and de Sitter attractor solutions. Two functional forms for the coupling functions and the scalar potential were considered: power-law and exponential functions of the scalar field. For power-law couplings, the restrictions on stable quintessence and phantom solutions lead to asymptotic freedom regime for the gravitational interaction. The model with dimensionless kinetic coupling constant gives stable de Sitter solutions. For the exponential functions the stable quintessence, phantom or de Sitter solutions, allow asymptotic behaviors where the effective Newtonian coupling can reach either the asymptotic freedom regime or constant value. The phantom solutions could be realized without appealing to ghost degrees of freedom. Transient inflationary and radiation dominated phases can also be described.

Charge modulations vs. strain waves in resonant x-ray scattering

description: A method is described for using resonant x-ray scattering to separately quantify the charge (valence) modulation and the strain wave associated with a charge density wave. The essence of the method is a separation of the atomic form factor into a "raw" amplitude, fR(w), and a valence-dependent amplitude, fD(w), which in many cases may be determined independently from absorption measurements. The advantage of this separation is that the strain wave follows the quantity |fR(w) + fD(w)|^2 whereas the charge modulation follows only |fD(w)|^2. This allows the two distinct modulations to be quantified separately. A scheme for characterizing a given CDW as Peierls-like or Wigner-like naturally follows. The method is illustrated for an idealized model of a one-dimensional chain.
