Examining Mental Health and Wellbeing Policies in Australian Universities
Authors: Ryan Tracii , Marangell Samantha , Baik Chi 
Published: March 2023

AbstractThe mental wellbeing of higher education students has become a salient issue facing higher education worldwide. This increased attention can be at least partially attributed to prevalence studies which indicate that the severity of mental health difficulties is growing across student populations, and a high proportion of students—higher than the general community—are experiencing moderate-to-severe levels of depression, anxiety, and stress. There has also been increasing recognition that universities have a critical role in providing supportive and health-promoting environments and developing whole-of-institution wellbeing policies. In addition to their moral imperative to ensure the safety of all students, supporting the mental health and wellbeing of students should be a priority for universities given that psychological distress is known to adversely affect students’ academic motivation, retention, and achievement. This is arguably even more important in the wake of COVID-19, which led to rapid changes in learning delivery, as well as a reduction in social connectedness and students’ perceptions of the quality of their university experience. This chapter examines the current state of play with regard to institutional mental health and wellbeing strategies and policies in the Australian higher education sector and suggests recommendations for future directions.
Speculating on Higher Education in 2041—Earthworms and Liminalities
Authors: Arndt Sonja , Belton Amanda , Cochrane Thomas , Healy Sarah , Gurr David 
Published: March 2023

AbstractWhat if… this chapter asks, might higher education be twenty years from now? This chapter speculates a future that takes place 20 years from now, a future that acknowledges the challenges of the present, as discussed at greater length in the earlier chapters. We take up speculative inquiry as a method to consider a future where the teens of 2021 bring their experience of living and learning during this pandemic time to the shaping and leadership of universities in 2041. Beginning with a what-if scenario of a reconceived higher education, we create a speculative fiction text—a letter from the future—around which we perform a diffractive reading (Barad, 2014). What this diffraction brings about is a higher education imaginary of activisms and revolts that result from current tensions and challenges in education and research. The imaginary does not predict the future but offers a critical lens through which to make sense of this present and the possible futures tied to it. In so doing, we suggest potentialities of practices like elevating decolonised ways of knowing and engaging geographical, human and nonhuman diversities in campuses across urban and remote areas. Traversing twenty years from now, the chapter speculates on higher education, spanning virtual and physical spaces for re-connection of research, learning and assessment with, in and through assemblies of diverse beings, human and otherwise. The chapter concludes with a codetta, which leaves the reader with a brief account of a speculative encounter with Socrabots as they prepare to enter the teaching profession in the 2040s.
The Teaching Profession: Where to from Here?
Authors: Klieve Sharon , Gillis Shelley , Smith Kylie , Arkoudis Sophie 
Published: March 2023

AbstractDuring the health crisis in Victoria, teachers were positioned as essential workers in the media and by government. Teachers were seen to play a critical role in minimizing the impacts of the health and economic crisis. At the system level, reactionary responses targeted online platforms and structures to support remote learning. Along with supporting learning, educators’ roles broadened to encompass the additional responsibilities of social and emotional support and wellbeing for their students, particularly those at risk of disengagement. This chapter will present four vignettes across early childhood, disability, vocational education, and English as an Additional Language (EAL) delivered within school contexts. The vignettes illuminate challenges faced by the teaching profession in maintaining equitable access and learning for diverse students. Issues around equity and inclusion have long existed in education. In recent times, policies have been employed as the means of achieving an equal playing field for all students. The vignettes highlight the challenges that continue around equity and inclusion. This chapter speculates on how higher education can reposition the complex role of the teaching profession in striving for inclusivity and equity in the constantly changing educational landscape. The chapter advocates for pedagogical and funding changes to support more interconnected and collaborative approaches to teaching.
N3LO quadratic-in-spin interactions for generic compact binaries
Authors: Kim Jung-Wook , Levi Michèle , Yin Zhewei 
Published: March 2023

Abstract
We derive the third subleading (N3LO) corrections of the quadratic-in-spin sectors via the EFT of spinning objects in post-Newtonian (PN) gravity. These corrections consist of contributions from 4 sectors for generic compact binaries, that enter at the fifth PN order. One of these contributions is due to a new tidal interaction, that is unique to the sectors with spin, and complements the first tidal interaction that also enters at this PN order in the simple point-mass sector. The evaluation of Feynman graphs is carried out in a generic dimension via advanced multi-loop methods, and gives rise to dimensional-regularization poles in conjunction with logarithms. At these higher-spin sectors the reduction of generalized Lagrangians entails redefinitions of the position beyond linear order. We provide here the most general Lagrangians and Hamiltonians. We then specify the latter to simplified configurations, and derive the consequent gauge-invariant relations among the binding energy, angular momentum, and frequency. We end with a derivation of all the scattering angles that correspond to an extension of our Hamiltonians to the scattering problem in the simplified aligned-spins configuration, as a guide to scattering-amplitudes studies.
Dark photon and dark Z mediated B meson decays
Authors: Datta Alakabha , Hammad A. , Marfatia Danny , Mukherjee Lopamudra , Rashed Ahmed 
Published: March 2023

Abstract
We study flavor changing neutral current decays of B and K mesons in the dark U(1)D model, with the dark photon/dark Z mass between 10 MeV and 2 GeV. Although the model provides an improved fit (compared to the standard model) to the differential decay distributions of B → K(∗)ℓ+ℓ−, with ℓ = μ, e, and Bs→ ϕμ+μ−, the allowed parameter space is ruled out by measurements of atomic parity violation, K+→ μ+ + invisible decay, and $$ {B}_s-{\overline{B}}_s $$

mixing, among others. To evade constraints from low energy data, we extend the model to allow for (1) additional invisible ZD decay, (2) a direct vector coupling of ZD to muons, and (3) a direct coupling of ZD to both muons and electrons, with the electron coupling fine-tuned to cancel the ZD coupling to electrons via mixing. We find that only the latter case survives all constraints.
The desert and the swampland
Authors: Long Cody , Montero Miguel , Vafa Cumrun , Valenzuela Irene 
Published: March 2023

Abstract
The most natural expectation away from asymptotic limits in moduli space of supergravity theories is the desert scenario, where there are few states between massless fields and the quantum gravity cutoff. In this paper we initiate a systematic study of these regions deep in the moduli space, and use it to place a bound on the number of massless modes by relating it to the black hole species problem. There exists a consistent sub-Planckian UV cutoff (the species scale) which resolves the black hole species problem without bounding the number of light modes. We reevaluate this in the context of supersymmetric string vacua in the desert region and show that even though heuristically the species scale is compatible with expectations, the BPS states of the actual string vacua lead to a stronger dependence of the cutoff scale on the number of massless modes. We propose that this discrepancy, which can be captured by the “BPS desert conjecture”, resurrects the idea of a uniform bound on the number of light modes as a way to avoid the black hole species problem. This conjecture also implies a stronger form of the Tadpole Conjecture, which leads to an obstruction in stabilizing all moduli semi-classically for large number of moduli in flux compactifications.
Simulating lepton number violation induced by heavy neutrino-antineutrino oscillations at colliders
Authors: Antusch Stefan , Hajer Jan , Rosskopp Johannes 
Published: March 2023

Abstract
We study pseudo-Dirac pairs of two almost mass-degenerate sterile Majorana neutrinos which generate light neutrino masses via a low-scale seesaw mechanism. These pseudo-Dirac heavy neutral leptons can oscillate between interaction eigenstates that couple to leptons and antileptons and thus generate oscillations between lepton number conserving and lepton number violating processes. With the phenomenological symmetry protected seesaw scenario (pSPSS), we introduce a minimal framework capable of describing the dominant features of low-scale seesaws at colliders and present a FeynRules implementation usable in Monte Carlo generators. Additionally, we extend MadGraph to simulate heavy neutrino-antineutrino oscillations and present results from such simulations.
Phase transitions and stability of Eguchi-Hanson-AdS solitons
Authors: Durgut Turkuler , Hennigar Robie A. , Kunduri Hari K. , Mann Robert B. 
Published: March 2023

Abstract
The Eguchi-Hanson-AdS5 family of spacetimes are a class of static, geodesically complete asymptotically locally AdS5 soliton solutions of the vacuum Einstein equations with negative cosmological constant. They have negative mass and are parameterized by an integer p ≥ 3 with a conformal boundary with spatial topology L(p, 1). We investigate mode solutions of the scalar wave equation on this background and show that, similar to AdS5, the geometry admits a normal mode spectrum (i.e. solutions that neither grow or decay in time). In addition, we also discuss other geometric properties of these soliton spacetimes, including the behaviour of causal geodesics and their thermodynamic properties. We also point out a surprising connection with the AdS soliton.
Instantons on Young diagrams with matters
Authors: Chen Yanyan , Jiang Jiaqun , Nawata Satoshi , Shao Yilu 
Published: March 2023

Abstract
We present the unrefined instanton partition functions of various 5d gauge theories with matter beyond the fundamental representation as sums over Young diagrams. By using these explicit expressions, we verify a range of identities among the instanton partition functions predicted by Higgsing procedures of fivebrane web diagrams and representation theory.
Shifted homotopy analysis of the linearized higher-spin equations in arbitrary higher-spin background
Authors: Tarusov A. A. , Ushakov K. A. , Vasiliev M. A. 
Published: March 2023

Abstract
Analysis of the first-order corrections to higher-spin equations is extended to homotopy operators involving shift parameters with respect to the spinor Y variables, the argument of the higher-spin connection ω(Y) and the argument of the higher-spin zero-form C(Y). It is shown that a relaxed uniform (y + p)-shift and a shift by the argument of ω(Y) respect the proper form of the free higher-spin equations and constitute a one-parametric class of vertices that contains those resulting from the conventional (no shift) homotopy. A pure shift by the argument of ω(Y) is shown not to affect the one-form higher-spin field W in the first order and, hence, the form of the respective vertices.
Systematic study of one-loop realizations of d = 7 long-range 0νββ decay operators
Authors: Chen Ping-Tao , Ding Gui-Jun , Yao Chang-Yuan 
Published: March 2023

Abstract
We study the systematical one-loop decomposition of the dimension-7 long-range 0νββ decay operators. We find that there are 3 genuine one-loop topologies and 8 diagrams. The procedure to determine the SM quantum number assignments for both internal and external fields is presented. The Majorana neutrino mass in long-range 0νββ models is discussed. We also present a one-loop 0νββ decay model which produces Majorana neutrino mass at three-loop level. The phenomenological predictions for light neutrino mass and 0νββ decay half-life time including both mass mechanism and long-range contribution are studied.
Modular parallel transport of multiple intervals in 1+1-dimensional free fermion theory
Authors: Chen Bowen , Czech Bartłomiej , Hung Ling-Yan , Wong Gabriel 
Published: March 2023

Abstract
Modular parallel transport is a generalization of Berry phases, applied to modular (entanglement) Hamiltonians. Here we initiate the study of modular parallel transport for disjoint field theory regions. We study modular parallel transport in the kinematic space of multi-interval regions in the vacuum of 1+1-dimensional free fermion theory — one of the few theories for which modular Hamiltonians on disjoint regions are known. We compute explicitly the generators of modular parallel transport, and explain why their relatively simple form follows from a half-sided modular inclusion. We also compute explicitly the curvature two-form of modular parallel transport. We contrast all calculations with the expected behavior of modular parallel transport in holographic theories, emphasizing the role of non-local terms that couple distinct intervals.
Novel loop-diagrammatic approach to QCD θ parameter and application to the left-right model

The Circular Helical Staircase at Palazzo Spada
Authors: Mancini Matteo Flavio , Farroni Laura 
Published: March 2023

AbstractThe paper deals with the unpublished survey and geometric analysis of the circular helical staircase built around 1660 in Palazzo Spada’s wing on Via del Polverone in Rome. Its role in the development of the place and the history of its design process are addressed thanks to historical drawings and the reference model proposed both in the treatise and construction between the fifteenth and seventeenth centuries. A description of the 3D digital survey procedures is followed by the reconstruction of a NURBS 3D model that describes the staircase and its geometric properties. Three helical turns of the staircase undergo an in-depth analysis of the slope angle thanks to the development of the helical lines. This leads to the recognition of the main features of this staircase: its unique central structure; the implementation of geometrical proportions descending from Andrea Palladio’s treatise; the changes of the slope angle that characterize the staircase flights and the space they generate.
A Virtual Reconstruction of Gaudi’s Skyscraper Hotel Attraction Using Physics-Based Simulation
Authors: Luque-Sala Arnau , del Blanco García Federico Luis 
Published: March 2023

AbstractThis article aims to provide a virtual reconstruction of the skyscraper Hotel Attraction based on the original documentation, which makes it possible to analyze the project and propose hypotheses regarding the contradictory information in the original drawings. The geometry of the project has been defined using a physics-based simulation, emulating Gaudí’s methodology in his models. To define the curves, a model based on weighted hanging chains has been generated, using a system with springs and particles. This method has made it possible to precisely control the catenary deformation, avoiding the definition of each curve independently in favor of a unified approach. Over 300 m tall, the Hotel Attraction would have been the tallest skyscraper in the world at the time.

Remission einer therapierefraktären generalisierten pustulösen Psoriasis unter dem Interleukin-36-Rezeptor-Inhibitor Spesolimab
Authors: Müller Valentina Laura , Kreuter Alexander 
Published: March 2023

ZusammenfassungDie generalisierte pustulöse Psoriasis (GPP) ist eine inflammatorische Erkrankung, die prinzipiell lebensbedrohlich verlaufen kann. Im Gegensatz zur „klassischen“ Psoriasis (Psoriasis vulgaris) geht diese mit einer sterilen Pustelbildung auf erythematöser Haut einher. Bislang gab es in Europa keine suffiziente, zugelassene Therapieoption, sodass die für die Psoriasis vulgaris eingesetzten Medikamente auch bei der GPP Verwendung fanden. Neuere Studien belegen, dass bei der GPP oft eine Mutation des Interleukin-36-Rezeptor-Antagonisten (IL-36Ra) zu einer gesteigerten Inflammation und entsprechend zur Krankheitsaktivität führt. Wir berichten den Fall einer schweren GPP mit einer kompletten Remission nach 2‑maliger Gabe von Spesolimab, einem neuen Interleukin-36-Rezeptor-Antikörper.
Unbiased estimation of the OLS covariance matrix when the errors are clustered
Authors: Boot Tom , Niccodemi Gianmaria , Wansbeek Tom 
Published: March 2023

AbstractWhen data are clustered, common practice has become to do OLS and use an estimator of the covariance matrix of the OLS estimator that comes close to unbiasedness. In this paper, we derive an estimator that is unbiased when the random-effects model holds. We do the same for two more general structures. We study the usefulness of these estimators against others by simulation, the size of the t-test being the criterion. Our findings suggest that the choice of estimator hardly matters when the regressor has the same distribution over the clusters. But when the regressor is a cluster-specific treatment variable, the choice does matter and the unbiased estimator we propose for the random-effects model shows excellent performance, even when the clusters are highly unbalanced.
Differences in the prefrontal cortex responses of healthy young men performing either water-based or land-based exercise at light to moderate intensity
Authors: Hashitomi Tatsuya , Hoshi Daisuke , Fukuie Marina , Tarumi Takashi , Sugawara Jun , Watanabe Koichi 
Published: March 2023

AbstractCerebral blood flow increases more during water-based exercise than land-based exercise owing to the effects of end-tidal CO2 (PETCO2) and mean arterial pressure (MAP) changes due to water immersion. However, it is unclear whether oxygenated hemoglobin (oxy-Hb) concentrations in the prefrontal cortex (PFC) are increased more by water-based or land-based exercise. We hypothesized that oxy-Hb concentrations in the PFC are higher during water-based exercise than land-based exercise when the exercise intensity is matched. To test this hypothesis, 10 healthy participants (age: 24.2 ± 1.7 years; height: 1.75 ± 0.04 m; weight: 69.5 ± 5.2 kg) performed light- to moderate-intensity cycling exercise in water (water-based cycling (WC); chest-high water at 30 °C) and on land (LC). Stroke volume, cardio output, heart rate, MAP, respiratory rate, PETCO2, and oxy-Hb in the PFC were assessed during 15 min of exercise, with exercise intensity increased every 5 min. Both WC and LC significantly increased oxy-Hb concentrations in the PFC as exercise intensity was increased (intensity effect: p < 0.001). There was no significant difference in oxy-Hb concentrations during WC and LC in most prefrontal areas, although significant differences were found in areas corresponding to the left dorsolateral PFC (exercise effect: p < 0.001). Thus, WC and LC increase oxy-Hb concentrations in the PFC in a similar manner with increasing exercise intensity, but part of the PFC exhibits enhanced oxy-Hb levels during WC. The neural response of the PFC may differ during water-based and land-based exercise owing to differences in external information associated with water immersion.
