description: Modern radio telescopes, such as the Square Kilometre Array (SKA), will probe the radio sky over large fields-of-view, which results in large w-modulations of the sky image. This effect complicates the relationship between the measured visibilities and the image under scrutiny. In algorithmic terms, it gives rise to massive memory and computational time requirements. Yet, it can be a blessing in terms of reconstruction quality of the sky image. In recent years, several works have shown that large w-modulations promote the spread spectrum effect. Within the compressive sensing framework, this effect increases the incoherence between the sensing basis and the sparsity basis of the signal to be recovered, leading to better estimation of the sky image. In this article, we revisit the w-projection approach using convex optimisation in realistic settings, where the measurement operator couples the w-terms in Fourier and the de-gridding kernels. We provide sparse, thus fast, models of the Fourier part of the measurement operator through adaptive sparsification procedures. Consequently, memory requirements and computational cost are significantly alleviated, at the expense of introducing errors on the radio-interferometric data model. We present a first investigation of the impact of the sparse variants of the measurement operator on the image reconstruction quality. We finally analyse the interesting super-resolution potential associated with the spread spectrum effect of the w-modulation, and showcase it through simulations. Our C++ code is available online on GitHub.

description: Hořava-Lifshitz gravity has been proposed as a ghost-free quantum gravity model candidate with an anisotropic UV-scaling between space and time. We present here a cosmological background analysis of two different formulations of the theory, with particular focus on the running of the parameter $λ$. Using a large dataset consisting of Cosmic Microwave Background data from {\it Planck}, Pantheon+ supernovae catalogue, SH0ES Cepheid variable stars, Baryon acoustic oscillations (BAO), Cosmic Chronometers, and gamma-ray bursts (GRB), we arrive at new bounds on the cosmological parameters, in particular $λ$, which describes deviation from classical general relativity. For the detailed balance scenario we arrive at the bound $λ=1.02726\pm0.00012$, and for beyond detailed balance the limit reads $λ=0.9949^{+0.0045}_{-0.0046}$. We also study the influence of different data sets and priors, and we find that removing low-redshift data generally moves $λ$ closer towards UV values, whilst simultaneously widening the error bars. In the detailed balance scenario, this effect is more noticeable, and $λ$ takes on values that are significantly below unity, which corresponds to the infrared limit of the theory.

description: Education for Sustainable Development is a key goal for LJMU, articulated in the Climate Change Action Plan and Learning & Teaching Strategy. These outline an expectation for considerations of climate awareness and sustainability to be integrated into the formal and informal curriculum across LJMU. This presents significant challenges, and this workshop will explore how the principles of sustainable development can be integrated into curricula and the wider student experience. Reflecting on examples from across LJMU and the HE sector as a whole, the session will examine the implications of Education for Sustainable Development for a range of university practices, including programme development, teaching, support and campus management. The workshop will provide an opportunity for delegates to recognise opportunities for embedding sustainability into their own area of work. It will encourage all of us to consider how the principles of Education for Sustainable Development can both challenge and enrich our practice Education for Sustainable Development in LJMU Powerpoint.

description: The galaxy cluster Abell~3376 is a nearby (z=0.046) dissociative merging cluster surrounded by two prominent radio relics and showing an X-ray comet-like morphology. The merger system is comprised of the subclusters A3376W & A3376E. Based on new deep multi-wavelength large-field images and published redshifts, we bring new insights about the history of this merger. Despite the difficulty of applying the weak lensing technique at such low redshift, we successfully recovered the mass distribution in the cluster field. Moreover, with the application of a two-body model, we have addressed the dynamics of these merging system. We have found the individual masses of M_{200}^{W}=3.0_{-1.7}^{+1.3}x10^{14} M_{\odot} and M_{200}^{E}=0.9_{-0.8}^{+0.5}x10^{14} M_{\odot}. The cometary shaped X-ray distribution shows only one peak spatially coincident with both Eastern BCG and the A3376E mass peak whereas the gas content of A3376W seems to be stripped out. Our data allowed us to confirm the existence of a third subcluster located at the North, 1147+-62 kpc apart from the neighbour subcluster A3376E and having a mass M_{200}^{N}=1.4_{-1.0}^{+0.7}x10^{14} M_{\odot}. From our dynamical analysis, we found the merging is taking place very close to the plane of the sky, with the merger axis just 10 deg +-11 deg from it. The application of a two-body analysis code showed that the merging cluster is seen 0.9_{-0.3}^{+0.2} Gyr after the pericentric passage and it is currently going to the point of maximum separation between the subclusters.

description: Agile Project Management is the dominant methodology for managing Software Development across the IT industry; and having been adopted by SME development teams and large development studios on multi-million-pound ventures alike, is one of the most sought-after soft skills in sector, particularly for Graduates. This talk reflects on transferring techniques practised from a highly successful 3-Year Knowledge Transfer Partnership (graded Outstanding by Innovate), which relied on the Agile process to keep the project alive and functioning efficiently over the COVID period, into the curriculum of our Computer Games Development and Software Engineering courses across all three years of our programme. We will discuss the principles of the Agile Manifesto (Beck et al, 2001) and how to reframe them into an academic setting to enhance collaboration, help students to plan and reflect and progress their work, to foster a closer communication bond with the academic teams and students, to measure and analyse incremental changes and add value to modules focused on more specific, knowledge-based learning outcomes. As we venture into a post-pandemic era of academic delivery, we will also look at how Agile fits into Remote Working Practices (Deshpande,2016) and the tools and technologies that can support this in practice both on and off-campus. Using practical examples of Agile configuration and collaboration tools and their application across three domain specific modules and their integration into a VLE, with the goals of: improving student performance in group courseworks; increasing their employability via soft skills outside the curriculum; increasing productivity across the semester; whilst simultaneously providing learning analytics and facilitating engaging formative feedback. We will conclude by discussing why Agile is not just for software, and how some of its key features can be adopted by the wider academic communities and the roles that Academics can play Embedding agile practices into the curriculum: a manifesto for proactivity Powerpoint.

description: We report resonant inelastic X-ray scattering (RIXS) measurements on ordered double perovskite samples containing Re$^{5+}$ and Ir$^{5+}$ with $5d^2$ and $5d^4$ electronic configurations respectively. In particular, the observed RIXS spectra of Ba$_2$YReO$_6$ and Sr$_2$MIrO$_6$ (M=Y, Gd) show sharp intra-t$_{2g}$ transitions, which can be quantitatively understood using a minimal `atomic' Hamiltonian incorporating spin-orbit coupling ($λ$) and Hund's coupling ($J_H$). Our analysis yields $λ=0.38(2)$eV with $J_H=0.26(2)$eV for Re$^{5+}$, and $λ=0.42(2)$eV with $J_H=0.25(4)$eV for Ir$^{5+}$. Our results provide the first sharp estimates for the Hund's coupling in $5d$ oxides, and suggest that it should be treated on equal footing with spin-orbit interaction in multi-orbital $5d$ transition metal compounds.

Switching MCQ exams from closed-book to online: time to re-visit assertion-reason questions?

Year: 2023

description: There has been a recent increase in the number of remote online exams within the Faculty of Science, replacing closed-book, in-person assessments. Online exams offer advantages in terms of convenience and accessibility for students, but present challenges around potential collusion and access to AI-enabled resources. Multiple-choice questions (MCQs), such as those deployed within Canvas quizzes, remain popular because they enable broad syllabus coverage and can challenge students’ recall of fundamental factual content. We argue that traditional MCQ exams are perhaps at the greatest risk of being undermined by a shift from in-person to remote format: setting challenging recall-type questions under open-book conditions is in itself a challenge. This session will present a proposed model for running online MCQ exams via Canvas using the wellestablished ‘assertion-reason’ MCQ type. Although originally envisaged as a means to assess understanding at higher levels, it is suggested that they could work equally well in testing elementary understanding in a contemporary environments where factual information is readily accessible online. In addition, it will be shown how native features of Canvas could be used to discourage collusion and address the potential for bias.

description: Tensor networks impose a notion of geometry on the entanglement of a quantum system. In some cases, this geometry is found to reproduce key properties of holographic dualities, and subsequently much work has focused on using tensor networks as tractable models for holographic dualities. Conventionally, the structure of the network - and hence the geometry - is largely fixed a priori by the choice of tensor network ansatz. Here, we evade this restriction and describe an unbiased approach that allows us to extract the appropriate geometry from a given quantum state. We develop an algorithm that iteratively finds a unitary circuit that transforms a given quantum state into an unentangled product state. We then analyze the structure of the resulting unitary circuits. In the case of non-interacting, critical systems in one dimension, we recover signatures of scale invariance in the unitary network, and we show that appropriately defined geodesic paths between physical degrees of freedom exhibit known properties of a hyperbolic geometry.

description: Experiential active learning has been shown to develop student skills, knowledge, abilities and confidence in their specific areas of study, whilst also preparing them for future work and their careers. University campus-based projects can provide excellent opportunities for experiential outdoor active learning, whilst also having the potential to provide both educational, health and wellbeing improvement benefits for students, staff and the wider university community. At last year’s Student at the Heart conference (2022) we presented our projected plans to engage students in nature based outdoor campus-based projects to enhance learning, health and well-being outcomes. This project has now physically commenced, and a range of activities have been undertaken and a range of resources developed for use within the LJMU community Activities and resources for campus-based staff and students developed as part of the herb garden project will be shared and discussed as part of the session. Longer term implications and the sustainability of this project and WRL opportunity, will also be examined. This presentation will: • Provide an updated overview of the herb garden project that has been undertaken and further developed this year here at LJMU • Outline the experiential active learning tasks undertaken by students as part of the project, • Discuss the critical learning and holistic personal outcomes for students and staff as a result of their participation. The student’s voices, engagement and attendance will be pivotal and central to this presentation. The students we have worked with this year will present alongside us, so that they can share their balanced, judicious reflections, thoughts and feelings about their WRL hybrid learning experience in the campus herb garden. Presentation links to the new LJMU strategy aims of: • Education and Student Experience: transforming lives and futures - examples of enhancing graduate employment prospects, diversifying, responsive support, delivering outstanding teaching and learning, providing an excellent student experience beyond the curriculum and supporting communities • Research and Knowledge Exchange: curiosity, creativity and impact - examples of teaching inspired by research, evidence-based service development, knowledge exchange, and student-led research Personal growth: using the LJMU herb garden to enhance student learning outcomes, confidence and well-being PowerPoint.

Formative conversations: developing dialogic exchanges around student feedback
Creators: name: Smith, Charlie
Publisher: name: Student Experience Proceedings
Year: 2023

description: There has been considerable energy invested in the move from transmission-based teaching toward more active, participative methods. However, whilst research on feedback has proposed similar moves toward dialogic methods with agentic student participation, arguably there has been less uptake of such methods in feedback practice. This presentation will discuss one approach to dialogic feedback – the design review. Commonly used throughout design education, the approach is also very comparable to verbal feedback on student presentations used in other disciplines. In theory, providing verbal feedback on students’ presentations in class aligns well with what Winstone and Carless (2020) describe as ‘learning-focused models of the feedback process’ (p. 2). It creates opportunity for students to elicit feedback, share meanings and clarify misunderstandings, and generate internal feedback through comparison with their peers. As such, there is considerable opportunity to enhance the student experience of their feedback. However, the design review has faced criticism, including the power asymmetry between students and teachers, and fostering an intimidating environment. This session will present initial findings from a study investigating dialogic feedback exchanges occurring during student presentations. The objective is to understand the nature of the interactions taking place, and the extent to which they effectively support student agency within the feedback process. The findings reveal that the feedback exchanges adopted a strong dialogic nature during the early stages; however, in the latter part of sessions feedback gravitated toward a more transmissive mode. These findings provide opportunity to apply and refine verbal exchanges in feedback practice, deepen students’ agentic participation in feedback approaches, and strengthen their contribution to their learning. Although studying feedback exchanges in an architecture programme, given the similarities to verbal feedback on student presentations used across other disciplines, the presentation will contribute to wider feedback practice and the development of dialogic feedback methods.

description: From our 2023-2030 Strategy, LJMU’s vision is to be an inclusive civic university. We can be proud of what we have already done to ensure our positive culture builds community, embraces diversity and supports well-being. We respond to modern-day challenges, reflecting our position at the heart of the Liverpool City Region and our standing nationally and internationally. Our Public Health programmes build upon our research excellence in substance use and the impact drug or alcohol use has on our communities. Our students include those with lived experience or who are in recovery, particularly within our Public Health (Addictions) Masters where our teaching reflects our commitment to breaking down stigma by having honest conversations about alcohol and other drugs. There are only a handful of UK universities that demonstrate a tangible commitment to promoting recovery and supporting those with lived experience of substance use. One way a university can do this is to sign up to the University Recovery Friendly Pledge. Alternatively, universities can engage with peer-led voluntary sector organisations to promote higher education as an invaluable opportunity to grow and learn which should be available to all. This lightning talk will aim to start a conversation about recovery in LJMU. If we are honest in our strategic commitment to retain our role as an agent of social mobility, what more might we want to do to promote recovery across the university and break down barriers for people in recovery? Should we be considering signing up to the University Recovery Pledge or are there other ways of embedding recovery in our approach to supporting a student’s journey?

description: Tensor-optimized antisymmetrized molecular dynamics (TOAMD) is the basis of the successive variational method for nuclear many-body problem. We apply TOAMD to finite nuclei to be described by the central interaction with strong short-range repulsion, and compare the results with the unitary correlation operator method (UCOM). In TOAMD, the pair-type correlation functions and their multiple products are operated to the AMD wave function. We show the results of TOAMD using the Malfliet-Tjon central potential containing the strong short-range repulsion. Adding the double products of the correlation functions in TOAMD, the binding energies are converged quickly to the exact values of the few-body calculations for s-shell nuclei. This indicates the high efficiency of TOAMD for treating the short-range repulsion in nuclei. We also employ the s-wave configurations of nuclei with the central part of UCOM, which reduces the short-range relative amplitudes of nucleon pair in nuclei to avoid the short-range repulsion. In UCOM, we further perform the superposition of the s-wave configurations with various size parameters, which provides a satisfactory solution of energies close to the exact and TOAMD values.

Latest widening participation data show that in 2018 – 19, just 13% of young people who met the government definition of a Former Relevant Looked After Child entered higher education, compared to 43% of all other pupils (DfE). As such, OfS has designated care experienced learners as a Priority Cohort to be included in institutional Access and Participation Plans for targeted support. LJMU has a long history of supporting care experienced students and those estranged from their families and, in 2022, was the first university to be awarded the National Network for the Education of Care Leavers (NNECL) Quality Mark for Higher Education outside of the pilot phase after undertaking a significant review of current LJMU provision and the submission of a three year institutional action plan. As part of this action plan, colleagues from the Faculty of Arts, Professional and Social Studies, the Teaching and Learning Academy and Student Advice and Wellbeing Services have initiated a cross-institutional research project utilising PhotoVoice to capture the experiences of students studying at Foundation and Level 4 in 2022 / 23.

description: Approximately 30,000 biomedical research abstracts are published each week on PubMed. This provides an enormous resource for new information that needs to be retrieved by individuals who desire access to it – researchers, industry, funders, policy makers, clinicians, patients, and the public. This enormous amount of information is retrieved using searches or tables of contents. However, these methods are overwhelming, broad and irrelevant. Biomed News is a free platform that provides a ranked abstract list on a weekly basis. Topic experts select abstracts relevant to their area of expertise. These selections are used by supervised machine learning to identify relevant papers in subsequent weekly issues. This reduces the amount of time required to identify new abstracts. Biomed News also provides an opportunity for selectors to share their weekly topic issues with other interested parties. Biomed News currently has around 80 experts from countries all over the world who are at different stages of their career. We aim for Biomed News to be a user-friendly platform in all areas of biomedical research that allows new abstracts to be identified and shared with interested parties.Biomed News aligns with LJMU strategies including Education and Student Experience as it will help students, especially post-graduate research students, to keep up with the literature in their field. Also, Biomed News will help in Research and Knowledge Exchange as this will help new research to be incorporated into teaching and also the exchange of the latest findings in the subject area.

On the Apparent Power Law in CDM Halo Pseudo Phase Space Density Profiles

description: We investigate the apparent power-law scaling of the pseudo phase space density (PPSD) in CDM halos. We study fluid collapse, using the close analogy between the gas entropy and the PPSD in the fluid approximation. Our hydrodynamic calculations allow for a precise evaluation of logarithmic derivatives. For scale-free initial conditions, entropy is a power law in Lagrangian (mass) coordinates, but not in Eulerian (radial) coordinates. The deviation from a radial power law arises from incomplete hydrostatic equilibrium (HSE), linked to bulk inflow and mass accretion, and the convergence to the asymptotic central power-law slope is very slow. For more realistic collapse, entropy is not a power law with either radius or mass due to deviations from HSE and scale-dependent initial conditions. Instead, it is a slowly rolling power law that appears approximately linear on a log-log plot. Our fluid calculations recover PPSD power-law slopes and residual amplitudes similar to N-body simulations, indicating that deviations from a power law are not numerical artefacts. In addition, we find that realistic collapse is not self-similar: scale lengths such as the shock radius and the turnaround radius are not power-law functions of time. We therefore argue that the apparent power-law PPSD cannot be used to make detailed dynamical inferences or extrapolate halo profiles inward, and that it does not indicate any hidden integrals of motion. We also suggest that the apparent agreement between the PPSD and the asymptotic Bertschinger slope is purely coincidental.

Scalar field dark matter in hybrid approach

description: We develop a hybrid formalism suitable for modeling scalar field dark matter, in which the phase-space distribution associated to the real scalar field is modeled by statistical equal-time two-point functions and gravity is treated by two stochastic gravitational fields in the longitudinal gauge (in this work we neglect vector and tensor gravitational perturbations). Inspired by the commonly used Newtonian Vlasov-Poisson system, we firstly identify a suitable combination of equal-time two-point functions that defines the phase-space distribution associated to the scalar field and then derive both a kinetic equation that contains relativistic scalar matter corrections as well as linear gravitational scalar field equations whose sources can be expressed in terms of a momentum integral over the phase-space distribution function. Our treatment generalizes the commonly used classical scalar field formalism, in that it allows for modeling of (dynamically generated) vorticity and perturbations in anisotropic stresses of the scalar field. It also allows for a systematic inclusion of relativistic and higher order corrections that may be used to distinguish different dark matter scenarios. We also provide initial conditions for the statistical equal-time two-point functions of the matter scalar field in terms of gravitational potentials and the scale factor.

Partnerships with work placement providers and professional identity: How can we improve the student experience?
Creators: name: McCooey, Thomas
Publisher: name: Student Experience Proceedings

description: Sometimes they are essential to fulfil the requirements of an industry’s standard benchmark. For example, in journalism this has been the case for many years with the National Council for the Training of Journalists, where a set number of work placement days are required to gain the organisation’s diploma in journalism, which many universities, including Liverpool John Moores, provides. But how well do work placements serve their purpose, and serve students about to embark on their careers? Many students get on well, and walk out of a placement after two weeks having boosted their desire to burst into the industry on the back of a wave of confidence-boosting experience. But some may see themselves as a burden to superiors pressed for time, and are perched in a corner of the office and forgotten about. They may leave demoralised and in some cases, re-evaluating their career plans. I have started to research the responsibility education and work placement providers have to ensure students get the best out of their placements through leading LJMU’s scheme with the Liverpool Echo. This is with a view to building tools which can hopefully enhance the student experience in what can be a daunting area. Sitting in any work environment as a student on placement can be a daunting prospect, and I want to use the experiences of students on The Echo scheme to put building blocks into place to ensure in future, more have a chance to prepare by knowing what to expect and how to navigate an experience which may be new to them. I will also use input from The Echo, and this research could be open to other partnership providers for other courses. This research, influenced by students, aims to promote graduate employment prospects and inclusivity, as students would be given access to more resources to help them prepare. At the conference, I would like to share what I have learned so far. Work placements are a common way to try and help prepare students for future employment.

description: This presentation will explore the aims, ambitions and impact of ‘Solidarity TV!’ – an outreach project piloted in Liverpool Screen School – which used the practice of reciprocal mentoring to create moments of understanding through the creation of a learning community between LJMU UG students and students from a global majority heritage who are currently studying in a local sixth form. In doing so, we will explore how and in what ways Solidarity TV! created an educational opportunity for academics, UG students, school students and technicians to come together and learn from one another through lived experience, professional practice, the acquisition of practical knowledge (for example learning how to operate technical equipment) and creative pedagogy. Alongside this, the paper will demonstrate how Solidarity TV! extended the view of a learning community as being situated within the university and addressed the power dynamics inherent in formal education. To conclude, we will illustrate how initiatives such as Solidarity TV! define learning as an ‘exchange of knowledge’ - with the technicians, UG students and school students all being viewed as equals and as experts within their areas.

description: Anisotropy endows topological aspects in optical systems and furnishes a platform to explore non-Hermitian physics, which can be harnessed for the polarization-selective amplification of light. Here, we show a zero-threshold Raman laser can be achieved in an anisotropic optical microcavity via polarization-controlled optical pumping. A loss-gain mechanism between two polarized Stokes modes arises naturally via polarization-dependent stimulated scattering and anisotropic Raman gain of the active layered material inside the microcavity. A Parity-Time (PT) symmetric Hamiltonian has been proposed to explain the emergence of a single polarization mode, essential for achieving a zero-threshold lasing condition. Additionally, intensity correlation measurements of the Stokes modes validate the coherence properties of the emitted light. Our realization of the zero-threshold Raman laser in anisotropic microcavity can open up a new research direction exploring non-Hermitian and topological aspects of light in anisotropic two-dimensional materials.

description: Technological progress consisting of the development of low-cost miniaturized sensors smartphone embedded and 5G infrastructure makes an effective fostering of diffuse data acquisition and citizen science for the earthquake defence and seismic risk mitigation strategies.
 We illustrate here the results of a project aimed at building an innovative solution based on Artificial Intelligence to provide increasingly accurate estimates of ground motion at local scale. The project has the aim of investigating the potential of enhancing the resolution of the earthquake impact reconnaissance
 with respect to site effects. The first phase is based on a specifically developed platform that collects data by an App installed on users' smartphones and then analyses the seismic parameters (i.e. Peak Ground Acceleration, PGA and Peak Ground Velocity, PGV) received at the built-in mobile device accelerometers.
 The test version of the Android mobile App uses a Machine Learning model trained on regional earthquake data.
 3 pairs of Android smartphones placed on seismic stations located in the Umbria region was used to collect real data to be used for ML model improvement and
