Publisher: name: F1000 Research Limited
Year: 2023

description: Introduction/Background
 The internet is a stable presence in our lives and has become increasingly interactive and pervasive thanks to smart devices and social media use. Tools such as Facebook, Twitter, Reddit, Instagram, and TikTok have provided new avenues for people to gather and connect with peers worldwide. Medical students are no exception: in-person interactions related to education within medical schools are now complemented by online interactions through social networks. These Medical Students Online Networks (MSONs) may be much larger than any medical school. MSONs are both an avenue to explore students’ perspectives and attitudes, and a source of culture and norms that students are exposed to, learn from, and participate in.

 Aim/Objectives
 We believe it is important to explore students’ use of large online networks of medical students, as content shared within MSONs contributes to their training. We aimed to understand the influence of interactions happening in these groups on the students’ learning, using the hidden curriculum theory as conceptual framework.

 Summary of Work
 After exploring online content related to medical education, we identified the MSONs on the public platform Reddit. We identified r/medicalschool as the largest MSON to date, extracted all content from it, and analysed it descriptively. Thematic analysis is being conducted; preliminary findings will be presented.

 Summary of Results
 As of February 6th 2023, r/medicalschool has 632,181 members, publishing approximately 63 posts and 561 comments each day. Over the past three years, r/medicalschool members tripled, and number of comments doubled. Content is primarily related to learning resources, postgraduate training, career opportunities, professionalism and students’ wellbeing. Posts are categorised by “flair”, which include “News”, “Serious”, “Preclinical”, “Clinical”, “Residency”, “Shitpost”, and “Meme”.

 Discussion and Conclusion
 MSONs currently complement medical schools' learning environment, contributing to informal and hidden curricula that students experience. MSONs' use is increasing, and students are exposed to a global digital learning environment in addition to the localised learning environment of their institution.

 Take Home Messages
 Medical educators are often unaware of the pervasiveness of MSONs, and of their influence on medical students. Further research is required to understand the prevalence of student engagement with MSONs, the influence MSONs have on students, and the implications of this phenomenon for medical educators.

description: Background
 The implementation of Competency-Based Medical Education (CBME) in postgraduate medical education across Canada aims to enhance training by fostering a personalized, learner-centered approach. The potential impact of CBME is disrupted by challenges and uncertainties during implementation, such as resident and preceptor roles and expectations. We examined the complex interactions during the provision and acquisition of workplace-based feedback to develop mental models that illustrate points of convergence and divergence between participant groups.

 Summary of Work
 Posters and email listservs were used to recruit participants from November 2019 - October 2021; 51 preceptors (n=25 non-CBME/traditional, n=26 CBME) and 94 residents (n=68 non-CBME/traditional, n=26 CBME). Through qualitative interviews, we utilized cognitive task analysis to capture complex cognitive processes of participants as they recalled how they engaged in the feedback exchange. We analyzed data through inductive thematic analysis to extract themes of the feedback process. We deductively mapped themes to macrocognitive functions (what) and processes (how) to describe how residents and preceptors think under complex conditions, in natural settings.

 Summary of Results
 Macrocognitive themes include functions (decision making, sensemaking, insight, complex learning) and processes (detecting problems, monitoring, managing risk, managing uncertainty, coordinating). Positive experiences involve all macrocognitive functions across both traditional and CBME curricula. The process of detecting problems is commonly identified in negative experiences, which compliments the recurrent identification of managing risks in positive experiences. Managing risks was also a recurrent theme in preceptors’ negative experiences compared to residents’. There was little to no difference in macrocognitive themes between CBME and traditional curricula across participants.

 Discussion and Conclusion
 The preceptor and resident macrocognitive patterns from this study contribute to the existing literature exploring early impact of CBME. This study presents mental models as perceived differences between preceptor and resident roles and the potential impact on feedback exchange. Future directions include exploring the stability (and malleability) of mental models over time as CBME becomes embedded and integrated further in contexts.

 Take Home Messages
 To achieve the potential impact of CBME, a culture shift is necessary for residents and preceptors to better understand each other's roles and expectations. This change in cognitive thinking is plausible if the system and innovation adapt alongside mental models.
Longitudinal training more effective than episodic time with experts

Publisher: name: F1000 Research Limited
Year: 2023

description: Introduction:
 After three decades of efforts to improve Mental and Behavioral Health (MBH) training for pediatricians in the United States (US), little progress has been made. The COVID-19 pandemic has exponentially increased pediatric mental health needs, and yet studies show graduates of US pediatric residency programs are inadequately prepared to manage these issues. Accreditation requirements for pediatric training programs focus on exposing trainees to experts. These have included a required block rotation in child development and behavioral pediatrics since 2000, and may soon require a Psychiatry rotation. Our pediatric residency program has tried these as well as other training approaches including integrating MBH specialists in the residents’ pediatric clinics. We conducted a qualitative study of graduates from our program to explore the factors impacting trainee ability to learn and later apply MBH in practice.

 Methods:
 We performed semi-structured interviews with graduates purposefully sampled from a 6-year period spanning the implementation of various MBH training approaches in our program. Participants were asked to reflect on their training and current practice, and discuss experiences that impacted their learning and use of MBH skills. We iteratively analyzed and coded the interview transcripts using the Consensual Qualitative Research method followed by abstraction and synthesis of themes.

 Results:
 Eleven graduates were interviewed. Factors impacting the learning and application of MBH skills centered around experiences that either facilitated or inhibited self-efficacy. Experiences where training had been ‘outsourced’ to non-pediatrician experts, the lack of modeling by pediatric faculty, episodic education resulting in limited exposure, and observation only learning environments limited the usefulness of training. Valuable experiences were those that provided ‘access to the specialist’ while caring for their own patients, graduated autonomy with scaffolded support, and environments that provided longitudinal education.

 Discussion/Conclusions:
 Consistent with experiential learning theory, sending trainees to ‘learn from experts’ is not enough to achieve MBH competence. Residents who developed MBH self-efficacy did so over time while providing the care to their own patients with support from mental health specialists integrated into their clinics.

 Take Home Message:
 Longitudinal training approaches allowing autonomy with graduated levels of support from knowledgeable faculty are more effective than episodic time with experts for learning complex skills.
Pharmacy technicians in primary care: A cost saving analysis towards role optimisation
Creators: name: Hamad, Hanan
name: Jalil, Majid
Publisher: name: F1000 Research Limited
Year: 2023

description: Background
 While primary care workforce is facing growing demands, the National Institute of Health and Social Care Research concluded recently that the introduction of skill mix employment in primary care did not reduce NHS expenditure or general practitioner (GP) workload (1). However, emerging evidence suggests that pharmacy professionals could substantially reduce GP’s medicines management workload (2). Engagement of other staff groups enhances the integration process and optimises role benefits. Latest evidence has led to inclusion of pharmacy technicians' role and training requirements in the Additional Role Reimbursement scheme (ARRs) (3).

 Aim:
 The study aims to investigate if the integration of pharmacy technicians in primary care offers perceived benefits for cost saving or reduction in GPs workload.

 Methods:
 Online survey of GPs in Thames Valley and Wessex region regarding perceived role of pharmacy technicians in primary care, the potential benefits and training needs.

 Summary of results:
 All respondents (100%) spend on average 6.5 hours a week on medication related queries. An additional average of 10.15 hours a week is spent on prescription signing tasks. Majority (88%) believe that pharmacy technicians could relieve part of the medication related queries. While (68%) believed that pharmacy technicians could help with reducing prescription signing tasks by managing the repeat dispensing process. Cost saving analysis revealed that pharmacy technicians could save GPs up to 10.75 hours (£677) a week. The need for extra support to train new recruits was highlighted by the majority (83%).

 Discussion and conclusion:
 GPs perceive potential reduction in workload due to pharmacy technicians’ contribution. Primary cost saving analysis indicates that savings could be made by more involvement of pharmacy technicians in primary care workforce. More support needed to optimise the training process.

 Take home messages:
 Staff engagement and good quality integration process enhances the potential benefits of the pharmacy technicians’ role in primary care.

description: In present work we study the production of ground and excited charmonium pairs in $e^- e^+ \rightarrow Ψ(nS)+ χ_{cJ}(nP)$ for $J=0,1$ and $n=1,2$, through leading order (LO) tree-level diagrams $\sim O(α_{em} α_s)$, which proceed through exchange of a virtual photon and an internal gluon line connecting two quark lines (in the triangle quark loop part of the diagram), in the framework of $4\times 4$ Bethe-Salpeter equation, at center of mass energy, $\sqrt{s}=10.6 GeV.$ We have tried to show that the cross sections for this process calculated with use of the four leading order $\sim O(α_{em} α_s)$ diagrams using BSE approach come close to experimental data, which might be mainly due to the consistent treatment of motion of quarks inside the hadrons in the BSE framework.

description: At colliders massive long-lived charged particles could be revealed through their anomalously large ionisation energy loss $dE/dx$. In this paper we explore a class of scenarios in which the LLPs are particularly boosted, owing to production from the decay of a heavy parent resonance. Such scenarios give rise to unique signatures as compared to traditionally considered $dE/dx$ new-physics benchmarks. We demonstrate that this class of models, unlike traditional new-physics theories, can explain the recently reported excess of events in the $dE/dx$ search by the ATLAS collaboration without conflicting with the determination of $β$ from ionisation and time-of-flight measurements.

description: While a quantum spin liquid (QSL) phase has been identified in the $J_1$-$J_2$ Heisenberg model on a triangular lattice via numerical calculations, debate persists about whether or not such a QSL is gapped or gapless, with contradictory conclusions from different techniques. Moreover, information about excitations and dynamics is crucial for the experimental detection of such a phase. In this work, we use exact diagonalization to characterize signatures of a QSL phase on the triangular lattice through the dynamical spin structure factor $\mathcal{S}(q,ω)$ and Raman susceptibility $\mathcalχ(ω)$. We find that spectra for the QSL phase show distinct features compared to those of neighboring phases; and both the Raman spectra and spin structure factor show gapped behaviour in the QSL phase. Interestingly, there is a prominent excitation mode in the Raman $A_2$ channel, indicating a strong subleading tendency toward a chiral spin liquid phase.

Neutron scattering and muon-spin spectroscopy studies of the magnetic triangular-lattice compounds $A_2$La$_2$NiW$_2$O$_{12}$ ($A$ = Sr, Ba)

description: We report on the geometrically frustrated two-dimensional triangular-lattice magnets $A_2$La$_2$NiW$_2$O$_{12}$ ($A$ = Sr, Ba) studied mostly by means of neutron powder diffraction (NPD) and muon-spin rotation and relaxation ($μ$SR) techniques. The chemical pressure induced by the Ba-for-Sr substitution suppresses the ferromagnetic (FM) transition from 6.3 K in the Ba-compound to 4.8 K in the Sr-compound. We find that the $R\bar{3}$ space group reproduces the NPD patterns better than the previously reported $R\bar{3}m$ space group. Both compounds adopt the same magnetic structure with a propagation vector $\boldsymbol{k} = (0, 0, 0)$, in which the Ni$^{2+}$ magnetic moments are aligned ferromagnetically along the $c$-axis. The zero-field {\textmu}SR results reveal two distinct internal fields (0.31 and 0.10 T), caused by the long-range ferromagnetic order. The small transverse muon-spin relaxation rates reflect the homogeneous internal field distribution in the ordered phase and, thus, further support the simple FM arrangement of the Ni$^{2+}$ moments. The small longitudinal muon-spin relaxation rates, in both the ferromagnetic- and paramagnetic states of A$_2$La$_2$NiW$_2$O$_{12}$, indicate that spin fluctuations are rather weak. Our results demonstrate that chemical pressure indeed changes the superexchange interactions in $A_2$La$_2$NiW$_2$O$_{12}$ compounds, with the FM interactions being dominant.

The $R_{\mathrm{h}}=ct$ universe and quintessence

description: Over the last few years the $R_{\mathrm{h}}=ct$ universe has received a lot of attention, particularly when observational evidence seems to favor this over the standard $Λ$ cold dark matter ($ΛCDM$) universe. Like the $ΛCDM$, the $R_{\mathrm{h}}=ct$ universe is based on a Friedmann-Robertson-Walker (FRW) cosmology where the total energy density $ρ$ and pressure $p$ of the cosmic fluid contain a dark energy component besides the usual (dark and baryonic) matter and radiation components. However unlike the $ΛCDM$ this model has the simple equation of state (EOS) $ρ+ 3p = 0$, i.e., its total active gravitational mass vanishes, which would therefore exclude a cosmological constant as the source of its dark energy component. Faced with this issue, in this paper we examine various possible sources for the dark energy component of the $R_{\mathrm{h}}=ct$ universe and show that quintessence which has been used in other various dynamical dark energy models could also be a possible source in this case.

description: These are the slides from the LIBER 2020 Session: Data Visualisation and Metrics. Session Description: In this session, three papers will be presented focusing on developments in the field of metrics and how these could aid libraries across Europe and worldwide. The first paper will help libraries to be equipped with better data to negotiate with publishers, communicate with the administration and faculty, and better understand their own serials collection spend and fulfillment. Jason Priem and Dr. Heather Piwowar will outline ways to forecast both the “read” side of your subscription spend and the “publish” side of article-processing charges (APCs) paid by your university, as well as fulfillment path forecasts over the next five years. They will discuss new metrics, open datasets and open tools to achieve the goal set above. The second presentation by Britt-Marie Wideberg and Anna Lundén will explore how the Steering Committee of the Bibsam Consortium plan to take action on the results of the study conducted by the National Library of Sweden, addressing future cost distribution scenarios, an international comparison, and a calculation of the financial impact of changing cost distribution models on participants of Consortium. They will subsequently focus on possible next steps on how to continue the work to find a fair and transparent internal cost allocation model. By sharing the insights from the study and the internal work currently in progress, they hope to share experiences gained so far and inspire and enter into dialogue with other interested libraries and consortia. The final talk will focus on the consideration of governance and appropriate use of performance metrics as an ongoing concern among the academic community. After Labour Action in October and November 2016, the mediated agreement included a recommendation to form a joint committee with a mandate to determine whether the collective agreement could include language restricting the use of performance metrics at an individual level. Andrea Szwajcer and Sherri Vokey will provide an instructive case study on the role of academic librarians’ evolving role in the responsible and ethical stewardship of metrics for libraries wishing to provide support services for bibliometric and related performance metrics-based services.

description: We introduce a mean field model based on realistic 2-body baryon interactions and calculate spectra of a set of p-shell and sd-shell Λ hypernuclei - 13ΛC, 17ΛO, 21ΛNe, 29ΛSi and 41ΛCa. The hypernuclear spectra are compared with the results of a relativistic mean field (RMF) model and available experimental data. The sensitivity of Λ single-particle energies to the nuclear core structure is explored. Special attention is paid to the effect of spin-orbit ΛN interaction on the energy splitting of the Λ single particle levels 0p3/2 and 0p1/2. In particular, we analyze the contribution of the symmetric (SLS) and the anti-symmetric (ALS) spin-orbit terms to the energy splitting. We give qualitative predictions for the calculated hypernuclei.

description: This paper introduces a novel neural network - flow completion network (FCN) - to infer the fluid dynamics, includ-ing the flow field and the force acting on the body, from the incomplete data based on Graph Convolution AttentionNetwork. The FCN is composed of several graph convolution layers and spatial attention layers. It is designed to inferthe velocity field and the vortex force contribution of the flow field when combined with the vortex force map (VFM)method. Compared with other neural networks adopted in fluid dynamics, the FCN is capable of dealing with bothstructured data and unstructured data. The performance of the proposed FCN is assessed by the computational fluiddynamics (CFD) data on the flow field around a circular cylinder. The force coefficients predicted by our model arevalidated against those obtained directly from CFD. Moreover, it is shown that our model effectively utilizes the exist-ing flow field information and the gradient information simultaneously, giving a better performance than the traditionalconvolution neural network (CNN)-based and deep neural network (DNN)-based models. Specifically, among all thecases of different Reynolds numbers and different proportions of the training dataset, the results show that the proposedFCN achieves a maximum norm mean square error of 5.86% in the test dataset, which is much lower than those of thetraditional CNN-based and DNN-based models (42.32% and 15.63% respectively).

description: This document is the final update of deliverables D6.4 [1] and D6.12 [2] and provides a description of the end-to-end (E2E) scenarios that explored how policy makers effectively used PolicyCLOUD platform as a part of the experimentation process. The given scenarios encompass the different steps required to perform the modelling, implementation and validation of the policies and include details of the necessary configuration settings needed in order to determine the output for the visualisation. The E2E stories were used to experiment the adaptability of the PolicyCLOUD platform in conjunction with several use case-based scenarios. This document describes all the workshops organized by the pilot users and all the scenarios integrated in the platform for each Use Case during the last months of the project (January 2022 – December 2022). The experimentation process for software usually consists of four phases definition, planning, operation and interpretation. Therefore, this approach was adopted for the design, implementation and experimentation of the E2E stories. Taking these four phases into consideration the E2E scenarios description has been used to implement the definition and planning stages. The E2E scenarios help to explore how well the PolicyCLOUD platform can be adapted for various situations. Finally, this deliverable describes the experimentation methodology adopted and how it has been applied to each use case. In particular, the details about the co-creation workshops are provided, including the agenda, list of participants, and a short summary of the general impressions and feedback.

description: In this paper we study the theoretical properties of the deflation-based FastICA method, the original symmetric FastICA method, and a modified symmetric FastICA method, here called the squared symmetric FastICA. This modification is obtained by replacing the absolute values in the FastICA objective function by their squares. In the deflation-based case this replacement has no effect on the estimate since the maximization problem stays the same. However, in the symmetric case a novel estimate with unknown properties is obtained. In the paper we review the classic deflation-based and symmetric FastICA approaches and contrast these with the new squared symmetric version of FastICA. We find the estimating equations and derive the asymptotical properties of the squared symmetric FastICA estimator with an arbitrary choice of nonlinearity. Asymptotic variances of the unmixing matrix estimates are then used to compare their efficiencies for large sample sizes showing that the squared symmetric FastICA estimator outperforms the other two estimators in a wide variety of situations.

description: We show that the geometric scaling of the dipole cross section can be explained using standard DGLAP perturbative evolution. The DGLAP improved saturation model due to the Laplace transforms method is considered at LO and NNLO approximations from the experimental data by relying on a Froissart-bounded parametrization of $F_{2}(x,Q^{2})$. These results are comparable with Golec-Biernat-W$\ddot{\mathrm{u}}$sthoff (GBW) model in a wide kinematic region $rQ_{s}$ which takes into account charm mass. The successful description of $σ_{\mathrm{dip}}(x,r)/σ_{0}$ and $σ_{\mathrm{dip}}(rQ_{s})/σ_{0}$ are presented.

The simple scheme provides an optical to terahertz conversion efficiency of 0.25% when pumped by a collimated laser pulses with duration of 50 fs and central wavelength of 800nm. The generated radiation spans frequencies between 0.2 and 3 THz. We measured the damage threshold as well as the dependency of the conversion efficiency on the pump fluence, pump wavelength, and pulse duration.
Quantifying Non-Markovianity in Open Quantum Dynamics

description: Characterization of non-Markovian open quantum dynamics is both of theoretical and practical relevance. In a seminal work [Phys. Rev. Lett. 120, 040405 (2018)], a necessary and sufficient quantum Markov condition is proposed, with a clear operational interpretation and correspondence with the classical limit. Here we propose two non-Markovianity measures for general open quantum dynamics, which are fully reconciled with the Markovian limit and can be efficiently calculated based on the multi-time quantum measurements of the system. A heuristic algorithm for reconstructing the underlying open quantum dynamics is proposed, whose complexity is directly related to the proposed non-Markovianity measures. The non-Markovianity measures and the reconstruction algorithm are demonstrated with numerical examples, together with a careful reexamination of the non-Markovianity in quantum dephasing dynamics.

description: We investigate a biaxial Bianchi IX model with positive cosmological constant, which is sometimes called the Lambda-Taub-NUT spacetime, whose exact solution is well known. The minisuperspace of biaxial Bianchi IX models admits two non-trivial Killing tensors that play an important role for deriving the Taub-NUT metric. We also give a brief discussion about the asymptotic behaviour of Bianchi IX models.

description: We propose a novel trajectory-optimized Cluster-based Network Model (tCNM) for nonlinear model order reduction from time-resolved data following Li et al. ["Cluster-based network model, " J. Fluid Mech. 906, A21 (2021)] and improving the accuracy for a given number of centroids. The starting point is k-means++ clustering which minimizes the representation error of the snapshots by their closest centroids. The dynamics is presented by 'flights' between the centroids. The proposed trajectory-optimized clustering aims to reduce the kinematic representation error further by shifting the centroids closer to the snapshot trajectory and refining state propagation with trajectory support points. Thus, curved trajectories are better resolved. The resulting tCNM is demonstrated for the sphere wake for three flow regimes, including the periodic, quasi-periodic, and chaotic dynamics. The representation error of tCNM is 5 times smaller as compared to the approximation by the closest centroid. Thus, the error at the same level as Proper Orthogonal Decomposition (POD) of same order. Yet, tCNM has distinct advantages over POD modeling: it is human interpretable by representing dynamics by a handful of coherent structures and their transitions; it shows robust dynamics by design, i.e., stable long-time behavior; and its development is fully automatable, i.e., it does not require tuneable auxiliary closure and other models.

description: The structural, electronic, and optical properties of flat and buckled AlN monolayers are investigated using first-principles approaches. The band gap of a flat AlN monolayer is changed from an indirect one to a direct one, when the planar buckling increases, primarily due to diminishing sp$^2$ overlapping and bond symmetry breaking in the conversion to sp$^3$ bonds. The sp$^3$ hybridization thus results in a stronger $σ\text{-}π$ bond rather than a $σ\text{-}σ$ covalent bond. The calculations of the phonon band structure indicates that the buckled AlN monolayers are structurally and dynamically stable. The optical properties, such as the dielectric function, the refractive index, and the optical conductivity of an AlN monolayer are evaluated for both flat systems and those impacted with planar buckling. The flat AlN monolayer has outstanding optical characteristics in the Deep-UV and absorbs more effectively in the UV spectrum due to its large band gap. The results reveal that optical aspects are enhanced along different directions of light polarization, with a considerable shift in the optical spectrum from Deep-UV into the visible range. Additionally, depending on the polarization direction of the incoming light, increased planar buckling enhances the optical conductivity in both the visible and the Deep-UV domains. The ability to modify the optical and electronic properties of these essential 2D materials using planar buckling technique opens up new technological possibilities, particularly for optoelectronic devices.

description: The fermionic and Majorana edge mode dynamics of various topological systems is compared, after a sudden global quench of the Hamiltonian parameters takes place. Attention is focused on the regimes where the survival probability of an edge state has oscillations either due to critical or off-critical quenches. The nature of the wave functions and the overlaps between the eigenstates of different points in parameter space determine the various types of behaviors, and the distinction due to the Majorana nature of the excitations plays a lesser role. Performing a sequence of quenches it is shown that the edge states, including Majorana modes, may be switched off and on. Also, the generation of Majoranas due to quenching from a trivial phase is discussed.

description: The doubled formulation of the worldsheet provides a description of string theory in which T-duality is promoted to a manifest symmetry. Here we extend this approach to $\mathcal{N}=(2,2)$ superspace providing a doubled formulation for bi-Hermitian/generalised Kähler target spaces. The theory is described by a single function, a doubled-generalised Kähler potential, supplemented with a manifestly $\mathcal{N}=(2,2)$ constraint. Several examples serve to illustrate this construction, including a discussion of the $\mathcal{N}=(2,2)$ description of T-folds.

description: This paper presents a novel method to estimate the power consumption of distinct active components on an electronic carrier board by using thermal imaging. The components and the board can be made of heterogeneous material such as plastic, coated microchips, and metal bonds or wires, where a special coating for high emissivity is not required. The thermal images are recorded when the components on the board are dissipating power. In order to enable reliable estimates, a segmentation of the thermal image must be available that can be obtained by manual labeling, object detection methods, or exploiting layout information. Evaluations show that with low-resolution consumer infrared cameras and dissipated powers larger than 300mW, mean estimation errors of 10% can be achieved.

description: We analyse the flow organization of turbulent fountains in stratified media under different conditions, using three-dimensional finite-time Lyapunov exponents. The dominant Lagrangian coherent structures responsible for the transport barriers in three different configurations suggest a self-similarity behaviour. After proposing a criterion for delimiting the boundary surface of the uprising fountain, we quantify the entrainment and re-entrainment rates under fully developed flow conditions using the proper coefficients. Finally, our analysis was applied to the Selective Inverted Sink, a technological application of turbulent fountains, identifying turbulence as the primary mechanism favouring the device's efficiency.

description: We investigate a holographic realization in Type-IIB string theory of pure Chern-Simons theories, and focus on the level/rank dualities that they enjoy. The level/rank duality is established between the boundary theory, engineered utilizing D3-branes compactified on a $S^1$, and the theory on probe D7-branes located at a specific bulk location. Paying attention to the boundary conditions imposed on the Ramond-Ramond (RR) two- and six-forms, we show that holography precisely reproduces several different level/rank dual pairs. The $SL(2,\mathbf{Z})$ action relating all these theories is realized through the $SL(2,\mathbf{Z})$ electric/magnetic duality involving the RR potentials.

description: Ultralight bosons can affect the dynamics of spinning black holes (BHs) via superradiant instability, which can lead to a time evolution of the supermassive BH shadow. We study prospects for witnessing the superradiance-induced BH shadow evolution, considering ultralight vector and tensor fields. We introduce two observables sensitive to the shadow time-evolution: the shadow drift, and the variation in the azimuthal angle lapse associated to the photon ring autocorrelation. The two observables are shown to be highly complementary, depending on the observer's inclination angle. Focusing on the supermassive object Sgr A$^\star$ we show that both observables can vary appreciably over human timescales of a few years in the presence of superradiant instability, leading to signatures which are well within the reach of the Event Horizon Telescope for realistic observation times (but benefiting significantly from extended observation periods), and paving the way towards probing ultralight bosons in the $\sim 10^{-17}\,{\rm eV}$ mass range.
