The role of Generative AI Test Ranges to protect online services from the impact of malicious synthetic content
Creators: name: Leckie, Christopher
Publisher: name: Zenodo
Year: 2023

description: Generative Artificial Intelligence (AI) has made remarkable progress in recent years in terms of the ability to automate the production of different types of content, such as long-format text, images, speech, music and video. While "off-the-shelf" generative AI tools are now widely available to assist in content generation for workplace and entertainment applications, the ready availability of these tools raises the question of how might criminal and other hostile actors use such tools for malign purposes?

Organisations such as Europol have already identified several possible scenarios where generative AI could be used to automate content generation for activities such as fraud, disinformation campaigns and cyber attacks. These malicious activities require the development of a new class of cyber defences that can detect synthetic content and identify its intent in specific application contexts.

To achieve this aim, we have been developing a Generative AI Test Range. This builds on our experience of cyber security test ranges to design an environment in which online services, such as social media channels, can be emulated in a closed environment, and subjected to attacks using malicious synthetic content. New defences can then be implemented and tested in the closed environment of the test range to assess their effectiveness against potential attacks.

Through the development of this generative AI test range, we can anticipate likely online threats of the future. This can inform the design of future services and prepare effective defences to mitigate the effects of malign content in a proactive rather than reactive manner.

description: Gravitational wave interferometers have proved the existence of a new class of binary black holes (BBHs) weighting tens of solar masses and they have provided the first reliable measurement of the rate of coalescing black holes (BHs) in the local universe. On another side, long gamma-ray bursts (GRBs) detected with gamma-ray satellites are believed to be associated with the birth of stellar mass BHs, providing a measure of the rate of these events across the history of the universe, thanks to the measure of their cosmological redshift. These two types of sources, which are subject to different detection biases and involve BHs born in different environments with potentially different characteristics, provide complementary information on the birth rate of stellar BHs. We compare here the birth rates of BHs found in BBH mergers and in long GRBs. We construct a simple model which makes reasonable assumptions on the history of GRB formation, and which takes into account some major uncertainties, like the beaming angle of GRBs or the delay between the formation of BBHs and their coalescence. We use this model to evaluate the ratio of the number of stellar mass BHs formed in BBH mergers to those formed in GRBs. We find that in our reference model the birth rate of stellar BHs in BBH mergers represents from few percent to 100% of the rate of long GRBs and that comparable birth rates are favored by models with moderate beaming angles. We briefly discuss this result in view of our understanding of the progenitors of GRBs and BBH mergers, and we emphasize that this ratio, which will be better constrained in the coming years, can be directly compared with the prediction of stellar evolution models if a single model is used to produce GRBs and of BBH mergers with the same assumptions.

Sharpend Cosine Similarity based Neural Network for Hyperspectral Image Classification
Creators: name: Ahmad, Muhammad
Publisher: name: arXiv
Year: 2023
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: Hyperspectral Image Classification (HSIC) is a difficult task due to high inter and intra-class similarity and variability, nested regions, and overlapping. 2D Convolutional Neural Networks (CNN) emerged as a viable network whereas, 3D CNNs are a better alternative due to accurate classification. However, 3D CNNs are highly computationally complex due to their volume and spectral dimensions. Moreover, down-sampling and hierarchical filtering (high frequency) i.e., texture features need to be smoothed during the forward pass which is crucial for accurate HSIC. Furthermore, CNN requires tons of tuning parameters which increases the training time. Therefore, to overcome the aforesaid issues, Sharpened Cosine Similarity (SCS) concept as an alternative to convolutions in a Neural Network for HSIC is introduced. SCS is exceptionally parameter efficient due to skipping the non-linear activation layers, normalization, and dropout after the SCS layer. Use of MaxAbsPool instead of MaxPool which selects the element with the highest magnitude of activity, even if it's negative. Experimental results on publicly available HSI datasets proved the performance of SCS as compared to the convolutions in Neural Networks.
Consistent Interactions between Gauge Fields and Local BRST Cohomology : The Example of Yang-Mills Models

description: Recent results on the cohomological reformulation of the problem of consistent interactions between gauge fields are illustrated in the case of the Yang-Mills models. By evaluating the local BRST cohomology through descent equation techniques, it is shown (i) that there is a unique local, Poincaré invariant cubic vertex for free gauge vector fields which preserves the number of gauge symmetries to first order in the coupling constant; and (ii) that consistency to second order in the coupling constant requires the structure constants appearing in the cubic vertex to fulfill the Jacobi identity. The known uniqueness of the Yang-Mills coupling is therefore rederived through cohomological arguments.

description: In this study we investigate the growth index $γ_L$, which characterizes the growth of linear matter perturbations, while analysing different cosmological datasets. We compare the approaches implemented by two different patches of the cosmological solver CAMB: MGCAMB and CAMB_GammaPrime_Growth. In our analysis we uncover a deviation of the growth index from its expected $Λ$CDM value of $0.55$ when utilizing the Planck dataset, both in the MGCAMB case and in the CAMB_GammaPrime_Growth case, but in opposite directions. This deviation is accompanied by a change in the direction of correlations with derived cosmological parameters. However, the incorporation of CMB lensing data helps reconcile $γ_L$ with its $Λ$CDM value in both cases. Conversely, the alternative ground-based telescopes ACT and SPT consistently yield growth index values in agreement with $γ_L=0.55$. We conclude that the presence of the A$_{\mathrm{lens}}$ problem in the Planck dataset contributes to the observed deviations, underscoring the importance of additional datasets in resolving these discrepancies.

description: We propose a scheme for the measurement of the s-wave scattering length $a$ of an atom or molecule with significant dipole-dipole interaction with an accuracy at the percent level. The frequencies of the collective oscillations of a Bose-Einstein condensate are shifted by the magnetic dipole interaction. The shift is polarization dependent and proportional to the ratio $ε_{dd}$ of dipolar and s-wave coupling constants. Measuring the differences in the frequencies for different polarization we can extract the value of $ε_{dd}$ and thus measure $a$. We calculate the frequency shifts for a large variety of non-axisymmetric harmonic traps in the Thomas-Fermi limit and find optimal trapping geometries to maximize the shifts.

description: Porous ceria for high temperature catalytic applications demands structural integrity concomitant with sinter resistance and improved gas permeability. The current state of the art hinges on complex synthesis methodologies which are not only expensive but also lack flexibility in pore tailorability. Hence, the development of porous scaffolds through low-cost processes without compromising on the functionality is in order. Herein, we demonstrate porous ceria with an open porosity of 88% developed through camphene assisted freeze casting for the first time. Microstructural evolution with different building blocks – micrometre-sized particles and short fibres were also studied. Preliminary catalytic activity obtained via temperature programmed reduction exemplified similar profiles showing no effect of the initial building blocks on the activity.

description: This work proposes provably-correct self-organizing strategies for platoons of heterogeneous vehicles. We refer to self-organization as the capability of a platoon to autonomously homogenize to a common group behavior. We show that self-organization promotes resilience to acceleration limits and communication failures, i.e., homogenizing to a common group behavior makes the platoon recover from these causes of impairments. In the presence of acceleration limits, resilience is achieved by self-organizing to a common constrained group behavior that prevents the vehicles from hitting their acceleration limits. In the presence of communication failures, resilience is achieved by self-organizing to a common group observer to estimate the missing information. Stability of the self-organization mechanism is studied analytically, and correctness with respect to traffic actions (e.g. emergency braking, cut-in, merging) is realized through a provably-correct safety layer. Numerical validations via the platooning toolbox OpenCDA in CARLA and via the CommonRoad platform confirm improved performance through self-organization and the provably-correct safety layer.

description: In conventional Bardeen-Cooper-Schrieffer (BCS) superconductors, electrons with opposite momenta bind into Cooper pairs due to an attractive interaction mediated by phonons in the material. While superconductivity naturally emerges at thermal equilibrium, it can also emerge out of equilibrium when the system's parameters are abruptly changed. The resulting out-of-equilibrium phases are predicted to occur in real materials and ultracold fermionic atoms but have not yet all been directly observed. Here we realize an alternate way to generate the proposed dynamical phases using cavity quantum electrodynamics (cavity QED). Our system encodes the presence or absence of a Cooper pair in a long-lived electronic transition in $^{88}$Sr atoms coupled to an optical cavity and represents interactions between electrons as photon-mediated interactions through the cavity. To fully explore the phase diagram, we manipulate the ratio between the single-particle dispersion and the interactions after a quench and perform real-time tracking of subsequent dynamics of the superconducting order parameter using non-destructive measurements. We observe regimes where the order parameter decays to zero (phase I), assumes a non-equilibrium steady-state value (phase II), or exhibits persistent oscillations (phase III). This opens up exciting prospects for quantum simulation, including the potential to engineer unconventional superconductors and to probe beyond mean-field effects like the spectral form factor, and for increasing coherence time for quantum sensing.

Non-Depth-First Search against Independent Distributions on an AND-OR Tree

description: Suzuki and Niida (Ann. Pure. Appl. Logic, 2015) showed the following results on independent distributions (IDs) on an AND-OR tree, where they took only depth-first algorithms into consideration. (1) Among IDs such that probability of the root having value 0 is fixed as a given r such that 0 < r < 1, if d is a maximizer of cost of the best algorithm then d is an independent and identical distribution (IID). (2) Among all IDs, if d is a maximizer of cost of the best algorithm then d is an IID. In the case where non-depth-first algorithms are taken into consideration, the counter parts of (1) and (2) are left open in the above work. Peng et al. (Inform. Process. Lett., 2017) extended (1) and (2) to multi-branching trees, where in (2) they put an additional hypothesis on IDs that probability of the root having value 0 is neither 0 nor 1. We give positive answers for the two questions of Suzuki-Niida. A key to the proof is that if ID d achieves the equilibrium among IDs then we can chose an algorithm of the best cost against d from depth-first algorithms. In addition, we extend the result of Peng et al. to the case where non-depth-first algorithms are taken into consideration.

A Roadmap for the Future of Shared Vocabularies in Australia: Harmonising Across Sectors, Disciplines and Internationally
Creators: name: McEachern, Steven
Publisher: name: Zenodo
Year: 2023

description: Shared Vocabularies form a key part of the Australian and international data landscape. Vocabularies, ontologies, classifications, glossaries and thesauri, form a key foundation for many data assets, services and infrastructure across the research, government and industry sectors. Formalised vocabularies capture expert knowledge, including definitions, in a form that can be used to organise and enrich data collections. Their use increases data interoperability by enhancing a shared understanding of the concepts used.

Shared Vocabularies and services supporting them form a diverse ecosystem in Australia that is not fully coordinated, meaning that many potentially valuable vocabularies are not discoverable or reusable by those communities that could benefit from their reuse.

In November 2022 a group of vocabulary experts came together in Canberra for a workshop to explore how the current ecosystem of vocabularies in Australia could be made more sustainable and broadly used. A draft roadmap has been developed for the future of the vocabulary ecosystem within Australia and more broadly.

The BoF will present key elements of the roadmap, including possible means for achieving a future state for the creation, management, use and sustainability of vocabularies.
This BoF will seek feedback on the draft roadmap and ask several questions of the audience:
 - Is there anything missing?
 - Are the perspectives of government, research and industry covered?
 - How does it align with equivalent initiatives internationally?
 - How do we best leverage cross-disciplinary commonalities?
 - What should the priorities be in the short and medium term?
Gravity or turbulence? IV. Collapsing cores in out-of-virial disguise

description: We study the dynamical state of cores by using a simple analytical model, a sample of observational massive cores, and numerical simulations of collapsing massive cores. From the model, we find that, if cores are formed from turbulent compressions, they evolve from small to large column densities, increasing their velocity dispersion as they collapse, while they tend to equipartition between gravity and kinetic energy. From the observational sample, we find that: (a) cores with substantially different column densities in the sample do not follow a Larson-like linewidth-size relation. Instead, cores with higher column densities tend to be located in the upper-left corner of the Larson velocity dispersion-size diagram, a result predicted previously (Ballesteros-Paredes et al. 2011a). (b) The data exhibit cores with overvirial values. Finally, in the simulations we reproduce the behavior depicted by the model and observational sample: cores evolve towards larger velocity dispersions and smaller sizes as they collapse and increase their column density. However, collapsing cores appear to approach overvirial states within a free-fall time. The cause of this apparent excess of kinetic energy is an underestimation of the gravitational energy, due to the assumption that the gravitational energy is given by the energy of an isolated sphere of constant column density. This excess disappears when the gravitational energy is correctly calculated from the actual spatial mass distribution, where inhomogeneities, as well as the potential due to the mass outside of the core, also contribute to the gravitational energy. We conclude that the observed energy budget of cores in surveys is consistent with their non-thermal motions being driven by their self-gravity and in a hierarchical and chaotic collapse.

On the O(1/N^2) Beta-Function of the Nambu-Jona-Lasinio Model with Non-Abelian Chiral Symmetry

description: We present the formalism for computing the critical exponent corresponding to the $β$-function of the Nambu--Jona-Lasinio model with $SU(M)$ $\times$ $SU(M)$ continuous chiral symmetry at $O(1/N^2)$ in a large $N$ expansion, where $N$ is the number of fermions. We find that the equations can only be solved for the case $M$ $=$ $2$ and subsequently an analytic expression is then derived. This contrasting behaviour between the $M$ $=$ $2$ and $M$ $>$ $2$ cases, which appears first at $O(1/N^2)$, is related to the fact that the anomalous dimensions of the bosonic fields are only equivalent for $M$ $=$ $2$.

Spin noise spectroscopy of randomly moving spins in the model of light scattering: Two-beam arrangement

description: A strict analytical solution of the problem of spin-noise signal formation in a volume medium with randomly moving spin carriers is presented. The treatment is performed in the model of light scattering in a medium with fluctuating inhomogeneity. Along with conventional single-beam, geometry, we consider the two-beam arrangement, with the scattering field of the auxiliary ("tilted") beam heterodyned on the photodetector illuminated by the main beam. It is shown that the spin noise signal detected in the two-beam arrangement is highly sensitive to motion (diffusion) of the spin carriers within the illuminated volume and thus can provide additional information about spin dynamics and spatial correlations of spin polarization in volume media. Our quantitative estimates show that, under real experimental conditions, spin diffusion may strongly suppress the spin-noise signal in the two-beam geometry. Mechanism of this suppression is similar to that of the time-of-flight broadening with the critical distance determined by the period of spatial interference of the two beams rather than by the beam diameter.
Total Variation-Based Dense Depth from Multi-Camera Array

description: Multi-Camera arrays are increasingly employed in both consumer and industrial applications, and various passive techniques are documented to estimate depth from such camera arrays. Current depth estimation methods provide useful estimations of depth in an imaged scene but are often impractical due to significant computational requirements. This paper presents a novel framework that generates a high-quality continuous depth map from multi-camera array/light field cameras. The proposed framework utilizes analysis of the local Epipolar Plane Image (EPI) to initiate the depth estimation process. The estimated depth map is then processed using Total Variation (TV) minimization based on the Fenchel-Rockafellar duality. Evaluation of this method based on a well-known benchmark indicates that the proposed framework performs well in terms of accuracy when compared to the top-ranked depth estimation methods and a baseline algorithm. The test dataset includes both photorealistic and non-photorealistic scenes. Notably, the computational requirements required to achieve an equivalent accuracy are significantly reduced when compared to the top algorithms. As a consequence, the proposed framework is suitable for deployment in consumer and industrial applications.

The amplitude fluctuation of a finite bandwidth introduces a low-lying spectral structure in the lineshape and thus its effect can be isolated from that of the phase fluctuation. Our technique provides extreme sensitivity suited for single-atom-level applications.

description: We show that certain type II string amplitudes at genus $g$ are given by the topological partition function $F_g$ discussed recently by Bershadsky, Cecotti, Ooguri and Vafa. These amplitudes give rise to a term in the four-dimensional effective action of the form $\sum_g F_g W^{2g}$, where $W$ is the chiral superfield of $N=2$ supergravitational multiplet. The holomorphic anomaly of $F_g$ is related to non-localities of the effective action due to the propagation of massless states. This result generalizes the holomorphic anomaly of the one loop case which is known to lead to non-harmonic gravitational couplings.

Functional form for the leading correction to the distribution of the largest eigenvalue in the GUE and LUE

Year: 2017
Subjects: subject: Mathematical Physics (math-ph)

description: The neighbourhood of the largest eigenvalue $λ_{\rm max}$ in the Gaussian unitary ensemble (GUE) and Laguerre unitary ensemble (LUE) is referred to as the soft edge. It is known that there exists a particular centring and scaling such that the distribution of $λ_{\rm max}$ tends to a universal form, with an error term bounded by $1/N^{2/3}$. We take up the problem of computing the exact functional form of the leading error term in a large $N$ asymptotic expansion for both the GUE and LUE --- two versions of the LUE are considered, one with the parameter $a$ fixed, and the other with $a$ proportional to $N$. Both settings in the LUE case allow for an interpretation in terms of the distribution of a particular weighted path length in a model involving exponential variables on a rectangular grid, as the grid size gets large. We give operator theoretic forms of the corrections, which are corollaries of knowledge of the first two terms in the large $N$ expansion of the scaled kernel, and are readily computed using a method due to Bornemann. We also give expressions in terms of the solutions of particular systems of coupled differential equations, which provide an alternative method of computation. Both characterisations are well suited to a thinned generalisation of the original ensemble, whereby each eigenvalue is deleted independently with probability $(1 - ξ)$. In the final section, we investigate using simulation the question of whether upon an appropriate centring and scaling a wider class of complex Hermitian random matrix ensembles have their leading correction to the distribution of $λ_{\rm max}$ proportional to $1/N^{2/3}$.

description: This presentation will introduce NewsTalk, a comprehensive data-as-a-service tool designed to empower researchers to investigate Australian public discourse on daily news topics. NewsTalk harvests data from dozens of Australian news platforms and supports extensive data exploration and data download functionality from a modern web app.  NewsTalk is a component in the ecosystem of resources being developed by the Australian Digital Observatory, a co-investment platform project with the Australian Research Data Commons, Queensland University of Technology, University of Melbourne, Queensland Cyber Infrastructure Foundation, University of New South Wales, and University of Queensland.

We explore the design and architecture of a modern research platform, incorporating backend infrastructure, modern web frontend, custom web harvesters, API services, and client-side Python modules. Services of this kind are typically costly to develop but we focus on a pattern shaped by modest eResearch resources. We discuss useful tactics such as cutting-edge server-side rendered web frameworks and deploying on Nectar ARDC Research Cloud.

Finally, we touch on the breadth of skills necessary for the future full-stack research software engineer to deploy similar research platforms.

description: In this paper, we present two non-perturbative string cosmological solutions without curvature singularities for the bosonic gravi-dilaton system. These solutions are general in the sense that they can straightforwardly match the perturbative solution to arbitrarily high orders in the perturbative region. The first solution includes non-perturbative $α'$ corrections based on Hohm-Zwiebach action. We then use the simple phenomenological map between $α^{\prime}$ corrected theory and loop corrected theory in string cosmology to construct a non-perturbative loop corrected non-singular solution. Both solutions are non-singular everywhere. Therefore, the pre- and post-big-bangs are smoothly connected by these solutions.

The Application of Preconditioned Alternating Direction Method of Multipliers in Depth from Focal Stack

description: Post capture refocusing effect in smartphone cameras is achievable by using focal stacks. However, the accuracy of this effect is totally dependent on the combination of the depth layers in the stack. The accuracy of the extended depth of field effect in this application can be improved significantly by computing an accurate depth map which has been an open issue for decades. To tackle this issue, in this paper, a framework is proposed based on Preconditioned Alternating Direction Method of Multipliers (PADMM) for depth from the focal stack and synthetic defocus application. In addition to its ability to provide high structural accuracy and occlusion handling, the optimization function of the proposed method can, in fact, converge faster and better than state of the art methods. The evaluation has been done on 21 sets of focal stacks and the optimization function has been compared against 5 other methods. Preliminary results indicate that the proposed method has a better performance in terms of structural accuracy and optimization in comparison to the current state of the art methods.

description: Suitable representations of dynamical systems can simplify their analysis and control. On this line of thought, this paper aims to answer the following question: Can a transformation of the generalized coordinates under which the actuators directly perform work on a subset of the configuration variables be found? Not only we show that the answer to this question is yes, but we also provide necessary and sufficient conditions. More specifically, we look for a representation of the configuration space such that the right-hand side of the dynamics in Euler-Lagrange form becomes $[\boldsymbol{I} \; \boldsymbol{O}]^{T}\boldsymbol{u}$, being $u$ the system input. We identify a class of systems, called collocated, for which this problem is solvable. Under mild conditions on the input matrix, a simple test is presented to verify whether a system is collocated or not. By exploiting power invariance, we provide necessary and sufficient conditions that a change of coordinates decouples the input channels if and only if the dynamics is collocated. In addition, we use the collocated form to derive novel controllers for damped underactuated mechanical systems. To demonstrate the theoretical findings, we consider several Lagrangian systems with a focus on continuum soft robots.
Free surface flows with large slopes: beyond lubrication theory
Creators: name: Snoeijer, Jacco H.

description: The description of free surface flows can often be simplified to thin film (or lubrication) equations, when the slopes of the liquid-gas interface are small. Here we present a long wavelength theory that remains fully quantitative for steep interface slopes, by expanding about Stokes flow in a wedge. For small capillary numbers, the variations of the interface slope are slow and can be treated perturbatively. This geometry occurs naturally for flows with contact lines: we quantify the difference with ordinary lubrication theory through a numerical example and analytically recover the full Cox-Voinov asymptotic solution.

Publisher: name: Zenodo

Subjects: Climate advocacy, policy change, political advocacy, public affairs

description: What can astronomers do to influence political processes to help change national
 policies? What can astronomers do to encourage funding agencies, universities and
 observatories to implement more climate friendly actions? Influencing political
 processes or organisational systems is a complex task involving grappling with
 changing contexts and beliefs, multiple stakeholders and multiple interests.
 What is the most effective strategy the astronomy community can take to move
 from communicating about climate change and raising awareness, to supporting
 climate action and achieve system change?
 Drawing from several experiences addressing challenging policy topics and from the
 body of knowledge in political science on policy change, I outline a few key
 principles which astronomers can adopt to engage effectively with policy and
 organisational systems: first, develop deep contextual knowledge of decision
 making in policy systems; second, build strong networks including authentic
 partnerships across coalitions, and third, participate for long periods of time in the
 system. With these principles in mind, I outline a specific template for development
 of policy advocacy and communication plan

description: In the above mentioned note (, , published in IEEE Trans. Autom. Cont., 2017), the first and fourth authors proved a local controllability result around the straight configuration for a class of magneto-elastic micro-swimmers.That result is weaker than the usual small-time local controllability (STLC), and the authors left the STLC question open. The present addendum closes it by showing that these systems cannot be STLC.
The impact of vorticity waves on the shock dynamics in core-collapse supernovae

description: Convective perturbations arising from nuclear shell burning can play an important role in propelling neutrino-driven core-collapse supernova explosions. In this work, we analyze the impact of vorticity waves on the shock dynamics and the post-shock flow using the solution of the linear hydrodynamics equations. We show that the entropy perturbations generated by the interaction of the shock with vorticity waves may play a dominant role in generating buoyancy-driven turbulence in the gain region. We estimate that the resulting reduction in the critical luminosity is 17-24%, which approximately agrees with the results of three-dimensional neutrino-hydrodynamics simulations.

description: Cooling of beams circulating in storage rings is critical for many applications including particle colliders and synchrotron light sources. A method enabling unprecedented beam-cooling rates, optical stochastic cooling (OSC), was recently demonstrated in the IOTA electron storage ring at Fermilab. This paper describes the numerical implementation of the OSC process in the particle-tracking program ELEGANT and discusses the validation of the developed model with available experimental data. The model is also employed to highlight some features associated with different modes of operation of OSC. The developed simulation tool should be valuable in guiding future configurations of optical stochastic cooling and, more broadly, modeling self-field-based beam manipulations.

Step-wise responses in mesoscopic glassy systems: a mean field approach

description: We study statistical properties of peculiar responses in glassy systems at mesoscopic scales based on a class of mean-field spin-glass models which exhibit 1 step replica symmetry breaking. Under variation of a generic external field, a finite-sized sample of such a system exhibits a series of step wise responses which can be regarded as a finger print of the sample. We study in detail the statistical properties of the step structures based on a low temperature expansion approach and a replica approach. The spacings between the steps vanish in the thermodynamic limit so that arbitrary small but finite variation of the field induce infinitely many level crossings in the thermodynamic limit leading to a static chaos effect which yields a self-averaging, smooth macroscopic response. We also note that there is a strong analogy between the problem of step-wise responses in glassy systems at mesoscopic scales and intermittency in turbulent flows due to shocks.

Visible Research Software Interest Group
Creators: name: Gustafsson, Johan
Publisher: name: Zenodo
Year: 2023

description: Visible research software are software outputs (source code, executables, workflows) that are made available by their authors, acknowledged in (re)use by other researchers, tracked and supported institutionally and linked to publications and data as part of the provenance of research findings or data handling. A key aspect of visibility is effective sharing. Streamlined approaches to research software sharing increases reuse of existing software, reduces replication of effort and directly supports an ecosystem where software developers gain visibility and recognition for their effort, expertise and fundamental contribution to research. In this BoF we will focus on what should be emerging best practice around software sharing in research: what can support staff do to better support this activity, what systems and processes can be used now, and what gaps need to be filled to do this adequately.

This BoF is an activity supported by the Visible Research Software Interest Group (VRSIG), which was launched in 2022 to address FAIR (findable, accessible, interoperable and reusable) research software and to also make progress by promoting a convergent community effort that describes the changes in culture, policy and practice that will lead to increased software visibility. In addition to the discussion on sharing software, this BOF will include a community update and an opportunity to continue planning VRSIG activities. We invite the community to join the group and the conversation: to make research software visible by connecting and collaborating in sharing knowledge, exchanging best practices, and minimising duplication of effort.
