Agape Open Science Community

description: This presentation was created for the ENLIGHT RISE and Arqus Ambassador Webinar Series on Open Science as the 4th presentation in this series.

Abstract

Embark on a journey with us as we recount our experiences navigating the realm of open science. Beginning with our serendipitous encounter, we found ourselves immersed in the ethos of open science and the wonderful opportunities and challenges it brings. Inspired by this experience, we founded AGAPE - a community dedicated to promoting open science among students and early career researchers. Join us as we share our story of discovery, getting lost, and ultimately finding our path within the open science community, and learn how AGAPE strives to be a beacon of inclusivity and support for open science enthusiasts.

Entanglement detection with imprecise measurements

description: We investigate entanglement detection when the local measurements only nearly correspond to those intended. This corresponds to a scenario in which measurement devices are not perfectly controlled, but nevertheless operate with bounded inaccuracy. We formalise this through an operational notion of inaccuracy that can be estimated directly in the lab. To demonstrate the relevance of this approach, we show that small magnitudes of inaccuracy can significantly compromise several renowned entanglement witnesses. For two arbitrary-dimensional systems, we show how to compute tight corrections to a family of standard entanglement witnesses due to any given level of measurement inaccuracy. We also develop semidefinite programming methods to bound correlations in these scenarios.

Higgs boson decays into a pair of heavy vector quarkonia

description: Rare Higgs decays into a pair of heavy vector quarkonia, $h\to VV$ ($V=J/Ψ$, $Υ$ etc.), have been investigated in the standard model. Different from the past literature in which these decays are thought to be only dominated by the longitudinally polarized final states, we also include the transitions, which proceed through $h\to γ^*γ^*$/$h\to Vγ^*$, followed by $γ^*\to V$. The final vector quarkonia via these ways are dominantly transversely polarized. Our calculation however shows that these transitions could lead to significant contributions to the decay rate, especially for the charmonium final states. The total branching ratios of these processes are predicted to be around $10^{-10}$, far below the current experimental upper bounds. Hopefully, experimental studies of these very rare decays in future high-precision experimental facilities might be interesting both to test the standard model and to look for new physics scenarios.

description: In this paper, two 8-point multiplication-free DCT approximations based on the Chen's factorization are proposed and their fast algorithms are also derived. Both transformations are assessed in terms of computational cost, error energy, and coding gain. Experiments with a JPEG-like image compression scheme are performed and results are compared with competing methods. The proposed low-complexity transforms are scaled according to Jridi-Alfalou-Meher algorithm to effect 16- and 32-point approximations. The new sets of transformations are embedded into an HEVC reference software to provide a fully HEVC-compliant video coding scheme. We show that approximate transforms can outperform traditional transforms and state-of-the-art methods at a very low complexity cost.

description: The Wnt signaling suppressor Notum is a promising target for osteoporosis, Alzheimer's disease, and colorectal cancers. To develop novel Notum inhibitors, we used an X-ray crystallographic fragment screen with the Diamond-SGC Poised Library (DSPL) and identified 59 fragment hits from the analysis of 768 data sets. Fifty-eight of the hits were found bound at the enzyme catalytic pocket with potencies ranging from 0.5 to >1000 μM. Analysis of the fragments' diverse binding modes, enzymatic inhibitory activities, and chemical properties led to the selection of six hits for optimization, and five of these resulted in improved Notum inhibitory potencies. One hit, 1-phenyl-1,2,3-triazole 7, and its related cluster members, have shown promising lead-like properties. These became the focus of our fragment development activities, resulting in compound 7d with IC50 0.0067 μM. The large number of Notum fragment structures and their initial optimization provided an important basis for further Notum inhibitor development.

description: Dietary carotenoids are associated with lower risk of CHD. Assessment of dietary carotenoid intake using questionnaires can be susceptible to measurement error. Consequently, there is a need to validate data collected from FFQs which measure carotenoid intake. This study aimed to assess the performance of the Cardio-Med Survey Tool (CMST)-FFQ-version 2 (v2) as a measure of dietary carotenoid intake over 12-months against plasma carotenoids biomarkers and 7-Day Food Records (7DFR) in an Australian cardiology cohort. Dietary carotenoid intakes (β- and α-carotene, lycopene, β-cryptoxanthin and lutein/ zeaxanthin) were assessed using the 105-item CMST-FFQ-v2 and compared to intakes measured by 7DFR and plasma carotenoid concentrations. Correlation coefficients were calculated between each dietary method, and validity coefficients (VCs) were calculated between each dietary method and theoretical true intake using the ‘methods of triads’. Thirty-nine participants aged 37–77 years with CHD participated in the cross-sectional study. The correlation between FFQ and plasma carotenoids were largest and significant for β-carotene (0.39, p=0.01), total carotenoids (0.37, p=0.02) and β-cryptoxanthin (0.33, p=0.04), with weakest correlations observed for α-carotene (0.21, p=0.21) and lycopene (0.21, p=0.21). The FFQ VCs were moderate (0.3–0.6) or larger for all measured carotenoids. The strongest were observed for total carotenoids (0.61) and β-carotene (0.59), while the weakest were observed for α-carotene (0.33) and lycopene (0.37). In conclusion, the CMST-FFQ-v2 measured dietary carotenoids intakes with moderate confidence for most carotenoids, however, there was less confidence in ability to measure α-carotene and lycopene intake, thus further research is warranted using a larger sample.

description: We present a stochastic model predictive control (SMPC) framework for linear systems subject to possibly unbounded disturbances. State of the art SMPC approaches with closed-loop chance constraint satisfaction recursively initialize the nominal state based on the previously predicted nominal state or possibly the measured state under some case distinction. We improve these initialization strategies by allowing for a continuous optimization over the nominal initial state in an interpolation of these two extremes. The resulting SMPC scheme can be implemented as one standard quadratic program and is more flexible compared to state-of-the-art initialization strategies. As the main technical contribution, we show that the proposed SMPC framework also ensures closed-loop satisfaction of chance constraints and suitable performance bounds.

description: The critical behavior of many physical systems involves two competing $n^{}_1-$ and $n^{}_2-$component order-parameters, ${\bf S}^{}_1$ and ${\bf S}^{}_2$, respectively, with $n=n^{}_1+n^{}_2$. Varying an external control parameter $g$, %(e.g. uniaxial stress or magnetic field), one encounters ordering of ${\bf S}^{}_1$ below a critical (second-order) line for $g<0$ and of ${\bf S}^{}_2$ below another critical line for $g>0$. These two ordered phases are separated by a first-order line, which meets the above critical lines at a bicritical point, or by an intermediate (mixed) phase, bounded by two critical lines, which meet the above critical lines at a tetracritical point. For $n=1+2=3$, the critical behavior around the (bi- or tetra-) multicritical point either belongs to the universality class of a non-rotationally invariant (cubic or biconical) fixed point, or it has a fluctuation driven first-order transition. These asymptotic behaviors arise only very close to the transitions. We present accurate renormalization-group flow trajectories yielding the effective crossover exponents near multicriticality.

description: Machine Learning (ML) techniques have been employed for the high energy physics (HEP) community since the early 80s to deal with a broad spectrum of problems. This work explores the prospects of using Deep Learning techniques to estimate elliptic flow ($v_2$) in heavy-ion collisions at the RHIC and LHC energies. A novel method is developed to process the input observables from particle kinematic information. The proposed DNN model is trained with Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV minimum bias events simulated with AMPT model. The predictions from the ML technique are compared to both simulation and experiment. The Deep Learning model seems to preserve the centrality and energy dependence of $v_2$ for the LHC and RHIC energies. The DNN model is also quite successful in predicting the $p_{\rm T}$ dependence of $v_2$. When subjected to event simulation with additional noise, the proposed DNN model still keeps the robustness and prediction accuracy intact up to a reasonable extent.

description: We consider the semiclassical quantization condition for the energy of an electron in a magnetic field in the case when the electron orbit lies on a Fermi-surface pocket surrounding the Weyl point of a topological semimetal and analyze the constant $γ$ appearing in this condition. It is shown that this constant has the universal value, $γ=0$, independent of the tilt of the Weyl spectrum. Since the constant $γ$ for an extremal cross section of the Fermi surface determines the phase of quantum oscillations, this result explains why measurements of the phase permit one to find Weyl points in crystals even though the extremal cross section of the pocket does not pass through this point, and the appropriate Berry phase of the orbit differs from $π$.

description: Existing studies on multimodal sentiment analysis heavily rely on textual modality and unavoidably induce the spurious correlations between textual words and sentiment labels. This greatly hinders the model generalization ability. To address this problem, we define the task of out-of-distribution (OOD) multimodal sentiment analysis. This task aims to estimate and mitigate the bad effect of textual modality for strong OOD generalization. To this end, we embrace causal inference, which inspects the causal relationships via a causal graph. From the graph, we find that the spurious correlations are attributed to the direct effect of textual modality on the model prediction while the indirect one is more reliable by considering multimodal semantics. Inspired by this, we devise a model-agnostic counterfactual framework for multimodal sentiment analysis, which captures the direct effect of textual modality via an extra text model and estimates the indirect one by a multimodal model. During the inference, we first estimate the direct effect by the counterfactual inference, and then subtract it from the total effect of all modalities to obtain the indirect effect for reliable prediction. Extensive experiments show the superior effectiveness and generalization ability of our proposed framework.

description: We elucidate the mechanisms that underly the formation of temporal localized states and frequency combs in vertical external-cavity Kerr-Gires-Tournois interferometers. We reduce our first principle model based upon delay algebraic equations to a minimal pattern formation scenario. It consists in a real cubic Ginzburg-Landau equation modified by high-order effects such as third order dispersion and nonlinear drift. The latter are responsible for generating localized states via the locking of domain walls connecting the high and low intensity levels of the injected micro-cavity. We interpret the effective parameters of the normal form in relation with the configuration of the optical setup. Comparing the two models, we observe an excellent agreement close to the onset of bistability.

description: The recently discovered C-19 stellar stream is a collection of kinematically associated metal-poor stars in the halo of the Milky Way lacking an obvious progenitor. The stream spans an arc of ~15 degrees in the sky, and orbit-fitting suggests an apocentric distance of ~20 kpc and a pericentre of ~10 kpc. The narrow metallicity dispersion of stars with available spectra, together with light element abundance variations, suggests a globular cluster (GC) origin. The observed metallicity ([Fe/H] ~ -3.4), however, is much lower than that of any known GC. In addition, the width and velocity dispersion of the stream are similar to those expected from disrupting dwarf galaxies, and substantially larger than the tidal debris of GCs able to disrupt on C-19's orbit. We propose here an unconventional model where the C-19 progenitor is a dark matter-dominated stellar system with GC-like abundance patterns. We use N-body simulations to show that the tidal disruption of a ~100 pc King-model stellar component embedded in a ~20 km/s cuspy cold dark matter halo yields debris consistent with C-19's observed width and velocity dispersion. The stellar component of the progenitor is fully disrupted, and is spread over two distinct streams; one corresponding to C-19 and another possibly hiding behind the Galactic plane. If such companion stream were found, it would suggest that dark matter-dominated dwarfs may also develop GC-like enrichment patterns, a finding that would inform our theoretical understanding of the formation of multiple populations in GCs and dwarf galaxies alike.

description: The Fisher information matrix (FM) plays an important role in forecasts and inferences in many areas of physics. While giving fast parameter estimation with the Gaussian likelihood approximation in the parameter space, the FM can only give the ellipsoidal posterior contours of parameters and lose the higher-order information beyond Gaussianity. We extend the FM in gravitational-wave (GW) data analysis using the Derivative Approximation for LIkelihoods (DALI), a method to expand the likelihood while keeping it positive definite and normalizable at every order, for more accurate forecasts and inferences. When applied to the two real GW events, GW150914 and GW170817, DALI can reduce the difference between FM approximation and the real posterior by 5 times in the best case. The calculation time of DALI and FM is at the same order of magnitude, while obtaining the real full posterior will take several orders of magnitude longer. Besides more accurate approximations, higher-order correction from DALI provides a fast assessment on the FM analysis and gives suggestions for complex sampling techniques which are computationally intensive. We recommend using the DALI method as an extension to the FM method in GW data analysis to pursue better accuracy while still keeping the speed.

Nudging policy: The role of knowledge in behavioural insights
Creators: name: Einfeld, Colette
Publisher: name: The Australian National University

description: Behavioural insights is used increasingly by governments around the world in designing public policy. It is an important addition to our knowledge about how policy works. However, little is known about policy actors' interpretation and use of different types of knowledge in the development and applications of behavioural insights. This omission matters because policy actors' privileging or excluding of different knowledges in policy making influences whose voices are heard, how problems are seen and framed, and what solutions are made possible (and preferable). Policy actors bring different forms of knowledge to policy making and, in making sense of policy problems and designing policy, shape policy processes. My research explores the question, how do policy actors interpret and use knowledge in behavioural insights? It has two lines of enquiry: which knowledges are used in behavioural insights, and do policy actors use knowledge instrumentally, politically or conceptually? I adopted an interpretive approach in my research in order to uncover the interpretations that shape policy actors' actions. The interpretations emerged from the analysis of thirty interviews with policy actors in Australia familiar with behavioural insights in their policy work. My findings demonstrate that it is important to pay attention to both what knowledge(s) are used and how they are used. I find policy actors interpret behavioural insights as an instrumental application of policy making that draws on and produces knowledge, with local knowledge struggling to fit into processes that privilege technical knowledge. Local and technical knowledges are interwoven with craft and normative knowledge as policy actors use knowledge politically to support their approach to behavioural insights, granting them resources and authority. These types of knowledge in behavioural insights influence how policy problems are interpreted, understood and addressed. My research contributes to understanding of behavioural insights as a policy approach, but also provides methodological insights into interpretive policy analysis by challenging the intentionality between interpretation and action. It contributes to the knowledge utilisation literature in describing the interdependent uses of instrumental, political and conceptual knowledge. Finally my research suggests that the uses of knowledge shape and are shaped by each other, and it is this 'system' that should be included in the study of knowledge in public policy.

description: This paper studies a novel privacy-preserving anonymization problem for pedestrian images, which preserves personal identity information (PII) for authorized models and prevents PII from being recognized by third parties. Conventional anonymization methods unavoidably cause semantic information loss, leading to limited data utility. Besides, existing learned anonymization techniques, while retaining various identity-irrelevant utilities, will change the pedestrian identity, and thus are unsuitable for training robust re-identification models. To explore the privacy-utility trade-off for pedestrian images, we propose a joint learning reversible anonymization framework, which can reversibly generate full-body anonymous images with little performance drop on person re-identification tasks. The core idea is that we adopt desensitized images generated by conventional methods as the initial privacy-preserving supervision and jointly train an anonymization encoder with a recovery decoder and an identity-invariant model. We further propose a progressive training strategy to improve the performance, which iteratively upgrades the initial anonymization supervision. Experiments further demonstrate the effectiveness of our anonymized pedestrian images for privacy protection, which boosts the re-identification performance while preserving privacy.

description: This study focuses on XenConservation's revelatory conservation communication in local governance, a small matrix of lowland freshwater mangrove wetland situated in Jimenez, Misamis Occidental, southern island of Mindanao, Philippines. A qualitative exploratory single case study in criterion-i purposeful sampling was employed to examine the nature of the conservation communication of the locale. The study revealed a transformative conservation communication in local governance continuum of care in private type governance alongside protected areas (PAs): convergent care, ancillary care, and diversified care, in a gradation of polarities within conservation communication in its conservation actions. In conclusion, the study theorizes in a constructivist and transformative worldview as a hobbyist in the in-situ conservation of threatened species. Tacit minority practice of affordances in a conservation communication's ancillary view of convergent-ancillary-diversified continuum of care encompasses a criterion-i conservation communication. Hence, a better protection policy and improved governance management for seasonal wetland and peatland of local conservation sites' agro-biodiversity and tree count status need to be strengthened.

Margin for Error: rules-based systems of painting and the anticipation of irregular outcomes.
Creators: name: Langridge, Emma
Publisher: name: The Australian National University
Year: 2022

description: My practice-led research explores modes of painting where restrictions on materials and methods generate unpredictable outcomes. I focus on non-objective, processed-based painting, employing rigorous and repetitive methodologies which, I will argue, are essentially a form of machine-mimicry. When the machine encounters a disrupting element, the task continues unabated, forming a glitch. This idea developed from an interrogation of my own art practice, in which a highly disciplined approach paradoxically precipitates the unpredictable bleed of paint, misalignments and inaccuracies. This has led me to explore self-imposed limitations and highly restricted visual vocabulary on the one hand, and the phenomena of glitch and malfunction on the other. I conduct an examination of motives, processes and materials in my own practice, determining the conditions which facilitate glitch and the particular form in which it is manifested. I focus on the history of glitch and malfunction in sound-related media, proposing that glitch can occur in the plastic arts under certain conditions created by the artist. I draw on the work of Sol Lewitt and Jack Whitten, as well as my contemporaries, in order to relate this tendency to a broader trend which confronts and ultimately embraces the aesthetics of decay, entropy, fracture and rupture. Initially I ask, what is glitch in non-objective, process-based painting and what criteria would need to be met for such a description? Coming to suspect that glitch may be an aesthetic dead-end, I develop tactics for development and expansion, via visual splits and ruptures, whilst maintaining my rules-based practice.

description: Solution and solid-state NMR spectroscopy are highly complementary techniques for studying structure and dynamics in very high molecular weight systems. Here we have analysed the dynamics of HIV-1 capsid (CA) assemblies in presence of the cofactors IP6 and ATPγS and the host-factor CPSF6 using a combination of solution state and cross polarisation magic angle spinning (CP-MAS) solid-state NMR. In particular, dynamical effects on ns to µs and µs to ms timescales are observed revealing diverse motions in assembled CA. Using CP-MAS NMR, we exploited the sensitivity of the amide/Cα-Cβ backbone chemical shifts in DARR and NCA spectra to observe the plasticity of the HIV-1 CA tubular assemblies and also map the binding of cofactors and the dynamics of cofactor-CA complexes. In solution, we measured how the addition of host- and co-factors to CA -hexamers perturbed the chemical shifts and relaxation properties of CA-Ile and -Met methyl groups using transverse-relaxation-optimized NMR spectroscopy to exploit the sensitivity of methyl groups as probes in high-molecular weight proteins. These data show how dynamics of the CA protein assembly over a range of spatial and temporal scales play a critical role in CA function. Moreover, we show that binding of IP6, ATPγS and CPSF6 results in local chemical shift as well as dynamic changes for a significant, contiguous portion of CA, highlighting how allosteric pathways communicate ligand interactions between adjacent CA protomers.

Prevalence of infection: 43 of 66 (65%) of A. quadriscutis; 23 of 28 (82%) of A. rugispinis; 17 of 19 (92%) of N. grandicassis; 100% of 84 S. proops; 12 of 13 (92%) of S. passany.
Remarks: The analysis of specimens of Chauhanellus parasitizing the gills of of A. quadriscutis, A. rugispinis, N. grandicassis, S. proops and S. passany indicated that they are conspecific with C. neotropicalis, based on the morphology of the male copulatory organ and haptoral structures. These specimens have a male copulatory organ with 1¼ counterclockwise rings and distal acute tip, ventral bar possessing postero-dorsal footlike protuberances, and dorsal bar with V-shaped with spine-like ends. The specimens collected from those hosts did not differ morphometrically from the type-host collected from the Brazilian Southern Coast, extending the distribution of C. neotropicalis to the North coast of Brazil.
