description: We apply the mimetic $f(T)$ theory into the thick brane model. We take the Lagrange multiplier formulation of the action and get the corresponding field equations of motion. We find solutions for different kinds of $f(T)$. Besides, we investigate the stability of the mimetic $f(T)$ brane by considering the tensor perturbations of the vielbein. Localization problem is also studied and it is shown that the four-dimensional gravity can be recovered for all the solutions. The effects of the torsion show that for the polynomial form of $f(T)$, the zero mode has a split compared with that of $f(T)=T$, but the situations for the exponential form of $f(T)$ are similar to that of $f(T)=T$.

description: We provide necessary and sufficient conditions for when an algebraic stack admits a good moduli space and prove a semistable reduction theorem for points of algebraic stacks equipped with a $Θ$-stratification. These results provide a generalization of the Keel--Mori theorem to moduli problems whose objects have positive dimensional automorphism groups and give criteria on the moduli problem to have a separated or proper good moduli space. To illustrate our method, we apply these results to construct proper moduli spaces parameterizing semistable $\mathcal{G}$-bundles on curves and moduli spaces for objects in abelian categories.

description: In this work, we present the analysis of 35,464 M-dwarf stars located within 100 parsecs in the Transiting Exoplanet Survey Satellite (TESS) Full Frame Images (FFIs) of the observed southern ecliptic hemisphere sectors 1 – 5. We present a new pipeline called NEMESIS which was developed to extract photometry, remove instrumental effects and perform transit searches of single sector data in TESS FFIs. As many M-dwarfs are faint and are not observed with a 2 minute cadence by TESS, FFI transit surveys can give an empirical validation of how many planets are missed by using the 30 minute cadence data. In this work, we detected 183 threshold crossing events and present 29 planet candidates for Sectors 1 – 5, 24 of which are new detections. Our sample contains orbital periods ranging from 1.25 – 6.84 days and planetary radii from 1.26 – 5.31 R⊕. We intend to extract light curves of other nearby M-dwarfs in TESS FFIs observed in Sectors 6 – 26 and will provide all of our data products for our planet candidates.

description: We are witnessing an increasing use of data-driven predictive models to inform decisions. As decisions have implications for individuals and society, there is increasing pressure on decision makers to be transparent about their decision policies. At the same time, individuals may use knowledge, gained by transparency, to invest effort strategically in order to maximize their chances of receiving a beneficial decision. Our goal is to find decision policies that are optimal in terms of utility in such a strategic setting. To this end, we first characterize how strategic investment of effort by individuals leads to a change in the feature distribution. Using this characterization, we first show that, in general, we cannot expect to find optimal decision policies in polynomial time and there are cases in which deterministic policies are suboptimal. Then, we demonstrate that, if the cost individuals pay to change their features satisfies a natural monotonicity assumption, we can narrow down the search for the optimal policy to a particular family of decision policies with a set of desirable properties, which allow for a highly effective polynomial time heuristic search algorithm using dynamic programming. Finally, under no assumptions on the cost individuals pay to change their features, we develop an iterative search algorithm that is guaranteed to find locally optimal decision policies also in polynomial time. Experiments on synthetic and real credit card data illustrate our theoretical findings and show that the decision policies found by our algorithms achieve higher utility than those that do not account for strategic behavior.

description: In recent years, deep learning methods applying unsupervised learning to train deep layers of neural networks have achieved remarkable results in numerous fields. In the past, many genetic algorithms based methods have been successfully applied to training neural networks. In this paper, we extend previous work and propose a GA-assisted method for deep learning. Our experimental results indicate that this GA-assisted approach improves the performance of a deep autoencoder, producing a sparser neural network.

description: Objective: The significantly higher incidence rates of microscopic colitis (MC) in Denmark compared to Sweden remains unexplained. Methods: Consecutive patients with newly diagnosed MC in the neighbouring regions of Skåne in 2011–2015 and Zealand in 2010–2016 were prospectively identified. Data on large bowel endoscopies and biopsies rates were retrieved. Information on putative factors were obtained from registers and literature. Interobserver agreement between pathologists from both regions on 40 blinded hematoxylin and eosin (H&E)-stained colon biopsies (collagenous colitis (CC), lymphocytic colitis (LC), non-specific inflammation and normal) was evaluated using kappa statistics. Results: The mean annual incidence per 105 inhabitants in Skåne and Zealand 2010–2015 was 5.9 (95% CI 4.6–7.3) versus 16.4 (95% confidence intervals (95% CI) 13.6–19.2) for CC and 2.7 (95% CI 1.0–4.3) versus 11.1 (95% CI 8.8–13.4) for LC, respectively. Number of endoscopies with biopsy per 1000 and the rate of MC per endoscopy with biopsy was higher in Zealand (34–52/1000) than in Skåne (12–21/1000). The kappa value for overall agreement between pathologists was good (0.72; 95% CI 0.64–0.79). Prescription of proton pump inhibitors and selective serotonin reuptake inhibitors was higher in Skåne in the relevant age groups and prescription of non-steroidal anti-inflammatory drugs and smoking rate higher in Zealand. Alcohol consumption was higher in Denmark than in Sweden. Conclusion: The incidence of MC and number of cases per colonic biopsy was higher in Zealand and could not be readily explained by endoscopy or biopsy rates, differences in histological assessment or putative risk factors.
Holographic Heat engine within the framework of massive gravity

description: Heat engine models are constructed within the framework of massive gravity in this paper. For the four-dimensional charged black holes in massive gravity, it is shown that the heat engines have a higher efficiency for the cases $m^2>0$ than for the case $m=0$ when $c_1<0, c_2<0$. Considering a specific example, we show that the maximum efficiency can reach $0.9219$ while the efficiency for $m=0$ reads $0.5014$. The existence of graviton mass improves the heat engine efficiency significantly. The situation is more complicated for the five-dimensional neutral black holes. Not only the $c_1, c_2, m^2$ exert influence on the efficiency, but also the constant $c_3$ corresponding to the third massive potential contributes to the efficiency. When $c_1<0, c_2<0, c_3<0$, the heat engine efficiency of the cases $m^2>0$ is higher than that of the case $m=0$. By studying the ratio $η/η_C$, we also probe how the massive gravity influences the behavior of the heat engine efficiency approaching the Carnot efficiency.

Emission from accelerating jets in gamma-ray bursts: Radiation dominated flows with increasing mass outflow rates

description: We study the narrowest spectra expected from gamma-ray bursts. We present an analytical function for the spectrum that is emitted from the photosphere of a radiation-dominated flow that is under acceleration. This is the narrowest possible spectrum and it differs from a Planck function. We also present numerical spectra from photospheres occurring during the transition into the coasting phase of the flow. Using these spectral models, we reanalyse Fermi observations of GRB100507 and GRB101219, which both have been reported to have very narrow spectra. The bursts can be fitted by the spectral models: For GRB101219 the spectrum is consistent with the photosphere occurring below or close to the saturation radius, while for GRB100507 the photosphere position relative to the saturation radius can be determined as a function of time. In the latter case, we find that the photosphere initially occurs in the acceleration phase and thereafter transitions into the coasting phase. We also find that this transition occurs at the same time as the change in observed cooling behaviour: the temperature is close to constant before the break and decays after. We argue that such a transition can be explained by an increasing mass outflow rate. Both analysed bursts thus give strong evidence that the jets are (initially) radiation dominated.

description: In preparation for a set of hydrodynamical simulations of core-collapse supernovae and protoneutron star winds, we investigate the rates of production and thermalization of $ν_μ$ and $ν_τ$ neutrinos in dense nuclear matter. Included are contributions from electron scattering, electron-positron annihilation, nucleon-nucleon bremsstrahlung, and nucleon scattering. We find that nucleon scattering dominates electron scattering as a thermalization process at neutrino energies greater than $\sim$15 MeV. In addition, nucleon-nucleon bremsstrahlung dominates electron-positron annihilation as a production mechanism at low neutrino energies, near and below the $ν_μ$ and $ν_τ$ neutrinospheres. Furthermore, we have begun a study of steady-state general relativistic protoneutron star winds employing simple neutrino heating and cooling terms. From this analysis we obtain acceleration profiles as well as asymptotic lepton fractions and baryon entropies essential in assessing the wind as a potential site for $r$-process nucleosynthesis.

Understanding our Research Data as an Asset

description: Morning focus: Characterising the Properties of our Data

Modern institutions routinely support digital research activities through an ever-increasing number of instrument capabilities, and data and compute services. This has greatly contributed to the amount of digital research content being generated and sustained, but little is known about its characteristics. The RDM Business Intelligence and Reporting project (commenced March 2023) aims to develop a taxonomy and reporting format for research data that satisfies local institutional needs while enabling sector-wide aggregation of data for benchmarking. This workshop will be the last of the three project workshops and will provide an opportunity for feedback on the developed taxonomy, reporting schema and updated estimates for Australia's retained data, and discuss strategies around its adoption and sustainability.

Afternoon Focus - Retiring and Retaining Data

Australian research institutions face a significant challenge arising from the uncontrolled expansion and indefinite retention of uncurated digital content associated with research activities. It is reasonable to think that only a portion of the digital content is research data and only some of that will meet the requirements for permanent retention. The Retention and Disposal of Research Data project (commenced March 2023) aims to develop a set of agreed best practices for the retention and disposal of research data, at various points through the research project lifecycle. This workshop will be the last of the three project workshops and aims for a broader review and adoption, and long-term sustainability of the agreed best practices recommendations developed throughout the project.

description: The present study investigated Italian consumers’ awareness, perception, knowledge of European Union (EU) quality certifications: Protected Designation of Origin (PDO), Protected Geographical Indication (PGI), Traditional Specialty Guar-anteed (TSG), and organic as well as the consumption of agri-food products carrying those certifications. A total of 212 consumers responsible for food purchases took part in a web-based survey between June and December 2019, inclusive. Descriptive sta-tistics were calculated in relation to the data collected, followed by a factor analysis to reduce data dimensionality, and a cluster analysis on the latent variables generated, to identify similarities and differences among respondents. Awareness, perception, knowl-edge and consumption of agri-food products carrying EU quality labels has increased among consumers in recent years. The results related to the consumer’s knowledge of quality-certified products showed that more than half of respondents were able to spontaneously quote examples of PDO (76%), PGI (56%) and organic food products (73%) while only 33% of participants could name at least one TSG product. The gener-al awareness of the guarantees offered by PDO and PGI certifications was also assessed in relation to production processes, the natural and human factors of a particular envi-ronment and the reputation and quality of a particular region. Cluster analysis showed that consumers with the highest education were most likely to value EU quality certi-fications and support their local economies. The information obtained have practical implications for marketing and communication of European certified food products at national and international level.

description: Interactions between atoms and light in optical cavities provide a means of investigating collective (many-body) quantum physics in controlled environments. Such ensembles of atoms in cavities have been proposed for studying collective quantum spin models, where the atomic internal levels mimic a spin degree of freedom and interact through long-range interactions tunable by changing the cavity parameters. Non-classical steady-state phases arising from the interplay between atom-light interactions and dissipation of light from the cavity have previously been investigated. These systems also offer the opportunity to study dynamical phases of matter that are precluded from existence at equilibrium but can be stabilized by driving a system out of equilibrium, as demonstrated by recent experiments. These phases can also display universal behaviors akin to standard equilibrium phase transitions. Here, we use an ensemble of about a million strontium-88 atoms in an optical cavity to simulate a collective Lipkin-Meshkov-Glick model, an iconic model in quantum magnetism, and report the observation of distinct dynamical phases of matter in this system. Our system allows us to probe the dependence of dynamical phase transitions on system size, initial state and other parameters. These observations can be linked to similar dynamical phases in related systems, including the Josephson effect in superfluid helium, or coupled atomic and solid-state polariton condensates. The system itself offers potential for generation of metrologically useful entangled states in optical transitions, which could permit quantum enhancement in state-of-the-art atomic clocks.

description: Flux-limited Keller-Segel (FLKS) model has been recently derived from kinetic transport models for bacterial chemotaxis and shown to represent better the collective movement observed experimentally. Recently, associated to the kinetic model, a new instability formalism has been discovered related to stiff chemotactic response. This motivates our study of traveling wave and aggregation in population dynamics of chemotactic cells based on the FLKS model with a population growth term. Our study includes both numerical and theoretical contributions. In the numerical part, we uncover a variety of solution types in the one-dimensional FLKS model additionally to standard Fisher/KPP type traveling wave. The remarkable result is a counter-intuitive backward traveling wave, where the population density initially saturated in a stable state transits toward an unstable state in the local population dynamics. Unexpectedly, we also find that the backward traveling wave solution transits to a localized spiky solution as increasing the stiffness of chemotactic response. In the theoretical part, we obtain a novel analytic formula for the minimum traveling speed which includes the counterbalancing effect of chemotactic drift vs. reproduction/diffusion in the propagating front. The front propagation speeds of numerical results only slightly deviate from the minimum traveling speeds, except for the localized spiky solutions, even for the backward traveling waves. We also discover an analytic solution of unimodal traveling wave in the large-stiffness limit, which is certainly unstable but exists in a certain range of parameters.

Subjects: subject: Probabilistic fracture, Polycrystals, Statistics, Microcrack, Intergranular fracture,

description: Using Monte Carlo simulation, the statistical properties of intergranular crack trajectories in polycrystalline materials are estimated. The polycrystalline microstructures are two dimensional and are modeled by a Poisson–Voronoi tessellation for the grain geometry and a uniform orientation distribution function for the crystallographic orientation. A heuristic is introduced for determining the path of crack propagation when the crack tip arrives at a grain boundary triple junction. This heuristic applies a combination of two criteria for determining the direction of crack propagation, the maximum circumferential stress criterion, and a criterion in which the crack is assumed to propagate in the direction with the least material resistance. The resistance of grain boundaries is assumed to be related to the crystallographic misorientation at the grain boundary. The trajectories of microcracks can be treated as a random process, and simulation results indicate that the crack process exhibits linear variance growth, the rate of which is related to the importance attached to the circumferential stress and the material resistance in determining the direction of propagation. The rate of variance growth is shown to vary with the average grain diameter, so that microcracks in polycrystals with small grain size will exhibit less spatial uncertainty. The statistics and distributions of the increments of the crack process are also given. Through a small change made to the normalization applied to non-dimensionalize the statistics, the results are extended to polycrystals that have spatially varying grain size. Finally, a probabilistic model is proposed that is able to produce synthetic crack trajectories that replicate the important statistical properties of the simulated cracks. Such a model may prove useful in studies of the transition from micro to macrocracking.

description: We consider spacetime described by observer that uses Trautman's retarded radial coordinates system. Given a metric tensor, we find all the symmetry maps. They set a 10 dimensional family of local diffeomorphisms of spacetime and can be parametrized by the Poincaré algebra. This result is similar to the symmetries of a Gauss observer using the Gauss simultaneous radial coordinates and experiencing the algebra deformation induced by the spacetime Riemann tensor. A new, surprising property of the retarded coordinates is that while the symmetries are differentiable, in general they are not differentiable twice. In other words, a family of smooth symmetries is smaller than in the Gaussian case. We demonstrate examples of that non-smoothness and find necessary conditions for the differentiability to the second order. We also discuss the consequences and relevance of that result for geometric relational observables program. One can interpret our result as that the retarded radial coordinates provide gauge conditions stronger that the Gaussian 4d radial gauge.

description: We study the non-equilibrium dynamics of conformal field theory (CFT) in 1+1 dimensions with a smooth position-dependent velocity $v(x)$ explicitly breaking translation invariance. Such inhomogeneous CFT is argued to effectively describe 1+1-dimensional quantum many-body systems with certain inhomogeneities varying on mesoscopic scales. Both heat and charge transport are studied, where, for concreteness, we suppose that our CFT has a conserved U$(1)$ current. Based on projective unitary representations of diffeomorphisms and smooth maps in Minkowskian CFT, we obtain a recipe for computing the exact non-equilibrium dynamics in inhomogeneous CFT when evolving from initial states defined by smooth inverse-temperature and chemical-potential profiles $β(x)$ and $μ(x)$. Using this recipe, the following exact analytical results are obtained: (i) the full time evolution of densities and currents for heat and charge transport, (ii) correlation functions for components of the energy-momentum tensor and the U$(1)$ current as well as for any primary field, and (iii) the thermal and electrical conductivities. The latter are computed by direct dynamical considerations and alternatively using a Green-Kubo formula. Both give the same explicit expressions for the conductivities, which reveal how inhomogeneous dynamics opens up the possibility for diffusion as well as implies a generalization of the Wiedemann-Franz law to finite times within CFT.

description: The quark flavor sector of the Standard Model is a fertile ground to look for new physics effects through a unitarity test of the Cabbibo-Kobayashi-Maskawa (CKM) matrix. We present a lattice QCD calculation of the scalar and the vector form factors (over a large $q^2$ region including $q^2 = 0$) associated with the $D \rightarrow Klν$ semi-leptonic decay. This calculation will then allow us to determine the central CKM matrix element, $V_{cs}$ in the Standard Model, by comparing the lattice QCD results for the form factors and the experimental decay rate. This form factor calculation has been performed on the $N_f =2+1+1$ MILC HISQ ensembles with the physical light quark masses.

description: COVID-19 has triggered an unprecedented global crisis, the increasing recessions in many countries and related trade uncertainties are affecting the whole wine sector, from production to distribution, sales, and consumption. While the full recovery is still uncertain, and even worse scenarios are possible if it takes longer to recover trust and financial stability on wine markets, the crisis risks to jeopardies recent developments and sustainability in wine territories. Building on a tailored revi-sion with a mixed-method participatory research process of the conceptual framework on Condition, Strategies, and Performance of Grando et al. (2020), we offer a critical reflection made by researchers and stakeholders supporting several socio-econom-ic narratives and policy implications in the light of the current crisis. Distinguishing between short and long-term implications, we analyse the impact of disruptive chang-es in the external and internal conditions of the business environment, the strategies adopted by the wineries and their implication on performances, as well as a reflec-tion on the policy needs to alleviate the ongoing suffering of the sector. The speed and scope of the pandemic crisis underscore the need for the wine sector to become more resilient by increasing the ability to cooperate and coordinate among supply chain actors and between policy levels. The latter offers a reflection on the balance between short-term interventions and the complementarity of post-2020 CAP measures to sta-bilize market and future incomes. We conclude that once the crisis abates, it will be necessary to reaffirm credible commitment and trust at all levels, not only with regard to production side but also on sale and distribution, especially in the face of changing consumption patterns that in the future will become more pressing for issues related to safety and sustainability.

How Training Development through Collaboration, can Support Organisational Strategies for Safe Data Management
Creators: name: Jones, Yolante
Publisher: name: Zenodo
Year: 2023

description: It almost seems a daily occurrence – another large-scale organisation is reporting a critical data breach. However, data breaches are being reported across all organisations, within the private sector, and public institutions continue to have their own internal discussions about gaps in policies, procedures and training.

Training materials to support the development of staff and students who work with data (especially sensitive data) continue to be a priority at varying levels. There has also been an increase in externally and internally funded projects that support the safe management of sensitive data. Training is becoming important to ensure the safe on-boarding of users as well as support the strategic priorities for the communities in which they operate.

This session will bring together a panel who have or continue to work on a platform that has training as a project output. The panel will explore the following:

* Why developing training was important for the panel member's platform?

* What was the process and what did collaboration look like?

* What were the challenges and will continue to be in the future?

* Recommendations for others who want to develop their own training

* Future proofing and developments
Topological orbital superfluid with chiral d-wave order in a rotating optical lattice

description: Topological superfluid is an exotic state of quantum matter that possesses a nodeless superfluid gap in the bulk and Andreev edge modes at the boundary of a finite system. Here, we study a multi-orbital superfluid driven by attractive s-wave interaction in a rotating optical lattice. Interestingly, we find that the rotation induces the inter- orbital hybridization and drives the system into topological orbital superfluid in accordance with intrinsically chiral d-wave pairing characteristics. Thanks to the conservation of spin, the topological orbital superfluid supports four rather than two chiral Andreev edge modes at the boundary of the lattice. Moreover, we find that the intrinsic harmonic confining potential forms a circular spatial barrier which accumulates atoms and supports a mass current under injection of small angular momentum as external driving force. This feature provides an experimentally detectable phenomenon to verify the topological orbital superfluid with chiral d-wave order in a rotating optical lattice.

description: We have revisited the epitaxial growth modes of Fe on W(110) and Mo(110), and propose an overview or our contribution to the field. We show that the Stranski-Krastanov growth mode, recognized for a long time in these systems, is in fact characterized by a bimodal distribution of islands for growth temperature in the range 250-700°C. We observe firstly compact islands whose shape is determined by Wulff-Kaischev's theorem, secondly thin and flat islands that display a preferred height, ie independant from nominal thickness and deposition procedure (1.4nm for Mo, and 5.5nm for W on the average). We used this effect to fabricate self-organized arrays of nanometers-thick stripes by step decoration. Self-assembled nano-ties are also obtained for nucleation of the flat islands on Mo at fairly high temperature, ie 800°C. Finally, using interfacial layers and solid solutions we separate two effects on the preferred height, first that of the interfacial energy, second that of the continuously-varying lattice parameter of the growth surface.

Permanence of large eddies in variable-density homogeneous turbulence with small Mach numbers

description: In this work, we study the large-scale structure of homogeneous flows displaying high density contrasts and small turbulent Mach numbers. Following Batchelor & Proudman (PTRSA 258, 1956), we draw an analogy between this configuration and that of a single isolated eddy displaying density non-uniformities. By doing so, we are able to highlight the crucial role played by the solenoidal component of the momentum in the preservation of initial conditions. In particular, we show that the large-scale initial conditions of the spectrum of the solenoidal momentum are preserved provided its infrared exponent is smaller than $4$. This condition is reminiscent of the one usually derived in constant density flow, except that it does not apply to the velocity spectrum. The latter is actually shown to be impermanent for infrared exponents larger or equal to $2$. The consequences of these properties on the self-similar decay of the flow are discussed. Finally, these predictions are verified by performing large eddy simulations of homogeneous isotropic turbulence.
Optimizing fingerprinting experiments for parameter identification: Application to spin systems

description: We introduce the Optimal Fingerprinting Process which is aimed at accurately identifying the parameters which characterize the dynamics of a physical system. A database is first built from the time evolution of an ensemble of dynamical systems driven by a specific field, which is designed by optimal control theory to maximize the efficiency of the recognition process. Curve fitting is then applied to enhance the precision of the identification. As an illustrative example, we consider the estimation of the relaxation parameters of a spin- 1/2 particle. The experimental results are in good accordance with the theoretical computations. We show on this example a physical limit of the estimation process.

description: Let ${\mathrm G}$ be the group $({\rm GL}_{2}\times {\rm GU}(1))/{\rm GL}_{1}$ over a totally real field $F$, and let $\mathscr{X}$ be a Hida family for ${\rm G}$. Revisiting a construction of Howard and Fouquet, we construct an explicit section $\mathscr{P}$ of a sheaf of Selmer groups over $\mathscr{X}$. We show, answering a question of Howard, that $\mathscr{P}$ is a universal Heegner class, in the sense that it interpolates geometrically defined Heegner classes at all the relevant classical points of $\mathscr{X}$. We also propose a `Bertolini-Darmon' conjecture for the leading term of $\mathscr{P}$ at classical points.
 We then prove that the $p$-adic height of $\mathscr{P}$ is given by the cyclotomic derivative of a $p$-adic $L$-function. This formula over $\mathscr{X}$ (which is an identity of functionals on some universal ordinary automorphic representations) specialises at classical points to all the Gross-Zagier formulas for ${\rm G}$ that may be expected from representation-theoretic considerations.
 Combined with a result of Fouquet, the formula implies the $p$-adic analogue of the Beilinson-Bloch-Kato conjecture in analytic rank one, for the selfdual motives attached to Hilbert modular forms and their twists by CM Hecke characters. It also implies one half of the first example of a non-abelian Iwasawa main conjecture for derivatives, in $2[F:{\bf Q}]$ variables. Other applications include two different generic non-vanishing results for Heegner classes and $p$-adic heights.
