description: The Rapid Transient Surveyor (RTS) is a proposed rapid-response, high-cadence adaptive optics (AO) facility for the UH 2.2-m telescope on Maunakea. RTS will uniquely address the need for high-acuity and sensitive near-infrared spectral follow-up observations of tens of thousands of objects in mere months by combining an excellent observing site, unmatched robotic observational efficiency, and an AO system that significantly increases both sensitivity and spatial resolving power. We will initially use RTS to obtain the infrared spectra of ~4,000 Type Ia supernovae identified by the Asteroid Terrestrial-Impact Last Alert System over a two year period that will be crucial to precisely measuring distances and mapping the distribution of dark matter in the z < 0.1 universe. RTS will comprise an upgraded version of the Robo-AO laser AO system and will respond quickly to target-of-opportunity events, minimizing the time between discovery and characterization. RTS will acquire simultaneous-multicolor images with an acuity of 0.07-0.10" across the entire visible spectrum (20% i'-band Strehl in median conditions) and <0.16" in the near infrared, and will detect companions at 0.5" at contrast ratio of ~500. The system will include a high-efficiency prism integral field unit spectrograph: R = 70-140 over a total bandpass of 840-1830 nm with an 8.7" by 6.0" field of view (0.15" spaxels). The AO correction boosts the infrared point-source sensitivity of the spectrograph against the sky background by a factor of seven for faint targets, giving the UH 2.2-m the H-band sensitivity of a 5.7-m telescope without AO.

description: Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics. We simulated AF with different severity grades of left-sided valvular diseases and compared the cardiovascular effects that they exert during AF, compared to lone AF. The fluid dynamics model used here has been recently validated for lone AF and relies on a lumped parameterization of the four heart chambers, together with the systemic and pulmonary circulation. Three different grades of severity (mild, moderate, severe) were analyzed for each of the four valvulopathies (aortic stenosis, mitral stenosis, aortic regurgitation, mitral regurgitation). Regurgitation was hemodynamically more relevant than stenosis, as the latter led to inefficient cardiac flow, while the former introduced more drastic fluid dynamics variation. Moreover, mitral valvulopathies were more significant than aortic ones. In case of aortic valve diseases, proper mitral functioning damps out changes at atrial and pulmonary levels. In the case of mitral valvulopathy, the mitral valve lost its regulating capability, thus hemodynamic variations almost equally affected regions upstream and downstream of the valve. The present study revealed that both mitral and aortic regurgitation strongly affect hemodynamics, followed by mitral stenosis, while aortic stenosis has the least impact among the analyzed valvular diseases. The proposed approach can provide new mechanistic insights as to which valvular pathologies merit more aggressive treatment of AF. Present findings, if clinically confirmed, hold the potential to impact AF management (e.g., adoption of a rhythm control strategy) in specific valvular diseases.

description: Relativistic fermions in topological quantum materials are characterized by linear energy-momentum dispersion near band crossing points. Under magnetic field, relativistic fermions acquire Berry phase of π in cyclotron motion, leading to a zeroth Landau level (LL) at the crossing point. Such field-independent zeroth LL, which distinguishes relativistic fermions from conventional electron systems, is hardly probed in transport measurements since the Fermi energy (EF) is usually not right at the band crossing points in most topological materials. Here we report the observation of exotic quantum transport behavior resulting from the zeroth LL in a multiband topological semimetal YbMnBi2 which possesses linear band crossings both at and away from the Fermi level (FL). We show that the Dirac bands with the crossing points being above or below the FL leads to Shubnikov de-Haas oscillations in the in-plane magnetoresistance, whereas the Dirac bands with the crossing points being at the FL results in unusual angular dependences of the out-of-plane magnetoresistance and in-plane Hall resistivity due to the dependence of the zeroth LL's degeneracy on field orientation. Our results shed light on the transport mechanism of the zeroth LL's relativistic fermions in layered materials.

description: Presented in this paper are measurements of an optomechanical device in which various acoustic modes of a sample of superfluid helium couple to a fiber-based optical cavity. In contrast with recent work on the paraxial acoustic mode confined by the cavity mirrors, we focus specifically on the acoustic modes associated with the helium surrounding the cavity. This paper provides a framework for understanding how the acoustic modes depend on device geometry. The acoustic modes are observed using the technique of optomechanically induced transparency/amplification. The optomechanical coupling to these modes is found to be predominantly photothermal.

description: Repositories have historically focused on retrospective capture of research products, reflecting existing. research recognition systems, which do not effectively recognise non-traditional (non-text) outputs created by researchers in arts and humanities disciplines. Bulley and Sahin (2021) define practice research as a "term that describes all manners of research where practice is the significant method of research conveyed in a research output." taking place across disciplines. In 2022, the UK's Arts and Humanities Research Council, funded two projects – Practice Research Voices (PRVoices) and Sustaining Practice Research Assets for Research, Knowledge, Learning and Engagement (SPARKLE). They built on work done by the University of Westminster and software company Cayuse, open standards work carried out by this team in collaboration with Jisc and the British Library, and the recommendations of the PRAG-UK reports. This presentation will present the findings and recommendations of both projects to move the repositories landscape towards becoming a platform for ongoing engagement throughout the research lifecycle and beyond, capturing process and product, enabling digital preservation, and subsequently embedding in open standards. This would lead to a more equitable open research landscape where all research is recognized, discoverable and preserved and all researchers benefit from the interoperability benefits this brings.

description: We investigate the presence of triangles in a class of correlated random graphs in which hidden variables determine the pairwise connections between vertices. The class rules out self-loops and multiple edges and allows for negative degree correlations (disassortative mixing) due to infinite-variance degrees controlled by a structural cutoff $h_s$ and natural cutoff $h_c$. We show that local clustering decreases with the hidden variable (or degree). We also determine how the average clustering coefficient $C$ scales with the network size $N$, as a function of $h_s$ and $h_c$. For scale-free networks with exponent $2

Closure of the Operator Product Expansion in the Non-Unitary Bootstrap

description: We use the numerical conformal bootstrap in two dimensions to search for finite, closed sub-algebras of the operator product expansion (OPE), without assuming unitarity. We find the minimal models as special cases, as well as additional lines of solutions that can be understood in the Coulomb gas formalism. All the solutions we find that contain the vacuum in the operator algebra are cases where the external operators of the bootstrap equation are degenerate operators, and we argue that this follows analytically from the expressions in arXiv:1202.4698 for the crossing matrices of Virasoro conformal blocks. Our numerical analysis is a special case of the "Gliozzi" bootstrap method, and provides a simpler setting in which to study technical challenges with the method. In the supplementary material, we provide a Mathematica notebook that automates the calculation of the crossing matrices and OPE coefficients for degenerate operators using the formulae of Dotsenko and Fateev.

description: The knowledge of frequencies of vibration of the first modes of minarets is essential to anticipate their behaviour under seismic loads. Masonry minarets are very slender structures with an extensive history of many centuries of construction and damages inflicted by earthquakes. Their construction techniques did not change much throughout the historical epochs, and only very recently, new minarets of the same type were built with Reinforced Concrete. Minarets lately have been the object of several studies because both the monitoring technologies for in-situ vibration observations and the existence of non-linear large-displacement software have become available. Many teams dedicated their attention to analysing frequencies of these structures and a few to study their behaviour. Several formulae were proposed to obtain frequencies as a function of their geometrical and mechanical characteristics, trying to arrive at some law valid for the set of minarets they studied. Others tried to extend their formulae to other slender traditional masonry structures such as towers, or chimneys. In this state-of-the-art review paper, the authors use a large set of data (79 Ottoman minarets) on frequency values as obtained by the authors as well as data compiled from the literature, to revisit this problem and discuss the details of how accurate the estimate of the frequencies might be. This large set confirms the trend of published formulae but includes uncertainties. A proposal for a simple formula, anchored on theoretical grounds, of the type f=α⋅√K/M +c=α⋅RgH2+c, is presented with a minimum number of aggregated variables and better Coefficient of determination, R2.

description: In the paper we present a low cost optical device which splits the light in the focal plane into two separate optical paths and collimates it back into a single image plane, and where a selective information processing ca be carried out. The optical system is straightforward and easy implementable as it consists of only three lens and two mirrors. The system is dedicated for imaging in low-light-level conditions in which widely used optical devices, based on beam-splitters or dichroic mirrors, suffer from light loss. We expose examples of applications of our device, using a prototype model. The proposed optical system may be employed for: monitoring the objects located in different distances from observer (1), creating regions of different magnification within a single image plane (2), high dynamic range photometry (3), or imaging in two wavelength bands simultaneously (4).

description: When electrons are driven through unconventional magnetic structures, such as skyrmions, they experience emergent electromagnetic fields that originate several Hall effects. Independently, ground state emergent magnetic fields can also lead to orbital magnetism, even without the spin-orbit interaction. The close parallel between the geometric theories of the Hall effects and of the orbital magnetization raises the question: does a skyrmion display topological orbital magnetism? Here we first address the smallest systems with nonvanishing emergent magnetic field, trimers, characterizing the orbital magnetic properties from first-principles. Armed with this understanding, we study the orbital magnetism of skyrmions, and demonstrate that the contribution driven by the emergent magnetic field is topological. This means that the topological contribution to the orbital moment does not change under continous deformations of the magnetic structure. Furthermore, we use it to propose a new experimental protocol for the identification of topological magnetic structures, by soft x-ray spectroscopy.

description: An interferometer has been used to measure the surface profile of generic object. Frequency scanning interferometry has been employed to provide unambiguous phase readings, to suppress etalon fringes, and to supersede phase-shifting. The frequency scan has been performed in three narrow wavelength bands, each generated by a temperature tuned laser diode. It is shown, that for certain portions of measured object, it was possible to get absolute phase measurement, counting all wave periods from the point of zero path difference, yielding precision of 2.7nm RMS over 11.75mm total path difference. For the other areas where steep slopes were present in object geometry, a relative measurement is still possible, at measured surface roughness comparable to that of machining process (the same 2.7nm RMS). It is concluded, that areas containing steep slopes exhibit systematic error, attributed to a combined factors of dispersion and retrace error.

description: Institutional repositories should carry the features of research information (RIS) and a performance evaluation system in addition to the existing features of IR. This provides a holistic perspective of institutions to their research ecosystems. IZTECH, believing in the transformation and development of IRs, started using GCRIS, Turkey's first and only IR and RIS at international standards, in 2021. Research outputs such as projects, awards, preprint publications, patents, and laboratory equipment have been added to the system, so IR content has been enriched, and all components in the research ecosystem have been made accessible. Everyone has equal access to all components through the technology and infrastructure facilities it uses. Thus, new collaborations, projects, and funding opportunities were created by increasing the institutions' and researchers' visibility. Studies are carried out to increase the research quality of the institution with the department and researcher-based academic performance evaluation system and advanced reports. As a result of the promotion and awareness visits made within the departments, the system received significant attention and support. Researchers started using the system actively, which has also been the primary source of strategic decision support for the university administration.

description: We present a detailed spectral analysis of XMM-Newton and NuSTAR observations of the accreting transient black hole GRS 1739-278 during a very faint low hard state at ~0.02% of the Eddington luminosity (for a distance of 8.5 kpc and a mass of 10 M_sun ). The broad-band X-ray spectrum between 0.5-60 keV can be well-described by a power law continuum with an exponential cutoff. The continuum is unusually hard for such a low luminosity, with a photon index of Gamma = 1.39 +/- 0.04. We find evidence for an additional reflection component from an optically thick accretion disk at the 98% likelihood level. The reflection fraction is low with R_refl = 0.043(+0.033,-0.023). In combination with measurements of the spin and inclination parameters made with NuSTAR during a brighter hard state by Miller and co-workers, we seek to constrain the accretion disk geometry. Depending on the assumed emissivity profile of the accretion disk, we find a truncation radius of 15-35 Rg (5-12 R_ISCO ) at the 90% confidence limit. These values depend strongly on the assumptions and we discuss possible systematic uncertainties.

description: We continue to study the response of black-hole space-times on the presence of additional strong sources of gravity. Restricting ourselves to static and axially symmetric (electro-)vacuum exact solutions of Einstein's equations, we first considered the Majumdar--Papapetrou solution for a binary of extreme black holes in a previous paper, while here we deal with a Schwarzschild black hole surrounded by a concentric thin ring described by the Bach--Weyl solution. The geometry is again revealed on the simplest invariants determined by the metric (lapse function) and its gradient (gravitational acceleration), and by curvature (Kretschmann scalar). Extending the metric inside the black hole along null geodesics tangent to the horizon, we mainly focus on the black-hole interior (specifically, on its sections at constant Killing time) where the quantities behave in a way indicating a surprisingly strong influence of the external source. Being already distinct on the level of potential and acceleration, this is still more pronounced on the level of curvature: for a sufficiently massive and/or nearby (small) ring, the Kretschmann scalar even becomes negative in certain toroidal regions mostly touching the horizon from inside. Such regions have been interpreted as those where magnetic-type curvature dominates, but here we deal with space-times which do {\em not} involve rotation and the negative value is achieved due to the {\em electric}-type components of the Riemann/Weyl tensor. The Kretschmann scalar also shapes rather non-trivial landscapes {\em outside} the horizon.

description: At the University of Toronto's Scarborough Library (UTSC) the Digital Scholarship Unit (DSU) a small, core technical team is tasked with developing and managing an infrastructure that supports multiple, diverse digital collections and digital scholarship projects. It is a constant challenge to meet the diverse needs of faculty partners and researchers without amassing unmanageable technical debt in the form of highly-individualized web applications that can cause challenges for maintenance and web-archiving longer-term. A decade-long collaboration between digital-humanities researcher and historian Dr. Natalie Rothman (UTSC Professor and Chair of the Department of Historical and Cultural Studies) and Kirsta Stapelfeldt (Librarian and Head of the DSU) for the Dragoman Renaissance Research platform has provided many opportunities for tackling the challenges of online interoperability, sustainability, and addressing complex research needs with limited resources. By prioritizing robust, iterative data modelling and core research and presentation functions over bespoke interfaces, the project aims to provide ample opportunities for data querying and reuse, while limiting long-term maintenance challenges. This presentation introduces the Islandora-based infrastructure at the UTSC's DSU and presents key features that may be of use to others tasked with supporting and stewarding an increasing number of online digital scholarship projects with limited resources.

description: CORE (https://core.ac.uk) works directly with the global network of Open Repositories, providing a range of tools and services for repositories and repository managers. This presentation introduces the newly updated CORE Repository Dashboard, a free service for repositories whose Open Access content is aggregated by CORE that delivers measurable benefits to repositories in two distinct areas. First, by providing a range of tools to assist in a range of repository management tasks and second, by greatly increasing discoverability of the repository's content. The Repository Dashboard enables managers to manage their content, provides reporting and download statistics, offers compliance checking against Open Access policies (such as REF in the United Kingdom), delivers the ability to register the repositories' OAI identifiers for global resolution with the CORE Resolver (https://oai.core.ac.uk/) and can automatically discover metadata enrichments (such as DOIs) for the repository's content from external sources and other repositories. Further, the Dashboard is the central hub for accessing other free services for data providers, such as CORE's Recommender and Discovery services.

description: Markarian 501 is a high-peaked BL Lacertae object and has undergone many major outburst since its discovery in 1996. As a part of the multiwavelength campaign, in the year 2009 this blazar was observed for 4.5 months from March 9 to August 1 and during the period April 17 to May 5 it was observed by both space and ground based observatories covering the entire electromagnetic spectrum. A very strong high energy $γ$-ray flare was observed on May 1 by Whipple telescope in the energy range 317 GeV to 5 TeV and the flux was about 10 times higher than the baseline flux. We use the photohadronic model complimented by the extragalactic background radiation (EBL) correction to this very high state flare and have shown that the EBL plays an important role in attenuating the very high energy flux even though Markarian 501 is in the local Universe.

On the wavelets-based SWIFT method for backward stochastic differential equations

description: We propose a numerical algorithm for backward stochastic differential equations based on time discretization and trigonometric wavelets. This method combines the effectiveness of Fourier-based methods and the simplicity of a wavelet-based formula, resulting in an algorithm that is both accurate and easy to implement. Furthermore, we mitigate the problem of errors near the computation boundaries by means of an antireflective boundary technique, giving an improved approximation. We test our algorithm with different numerical experiments.
Simulation of a low-background proton detector for studying low-energy resonances relevant in thermonuclear reactions

description: A new detector is being developed at the National Superconducting Cyclotron Laboratory (NSCL) to measure low energy charged-particles from beta-delayed particle emission. These low energy particles are very important for nuclear astrophysics studies. The use of a gaseous system instead of a solid state detector decreases the sensitivity to betas while keeping high efficiency for higher mass charged particles like protons or alphas. This low sensitivity to betas minimizes their contribution to the background down to 150 keV. A detailed simulation tool based on \textsc{Geant4} has been developed for this future detector.
