description: We use Gaia DR3 data to study the Collinder 132-Gulliver 21 region via the machine learning algorithm StarGO, and find eight subgroups of stars (ASCC 32, Collinder 132 gp 1--6, Gulliver 21) located in close proximity. Three co-moving populations were identified among these eight subgroups: (i) a coeval 25 Myr-old moving group (Collinder 132); (ii) an intermediate-age (50--100 Myr) group; and (iii) the 275 Myr-old dissolving cluster Gulliver 21. These three populations form parallel diagonal stripe-shape over-densities in the U--V distribution, which differ from open clusters and stellar groups in the solar neighborhood. We name this kinematic structure the Collinder 132-Gulliver 21 stream, as it extends over 270 pc in the 3D space. The oldest population Gulliver21 is spatially surrounded by the Collinder 132 moving group and the intermediate-age group. Stars in the Collinder 132-Gulliver 21 stream have an age difference up to 250 Myr. Metallicity information shows a variation of 0.3 dex between the youngest and oldest populations. The formation of the Collinder132-Gulliver 21 stream involves both star formation and dynamical heating. The youngest population (Collinder 132 moving group) with homogeneous metallicity is probably formed through filamentary star formation. The intermediate-age and the oldest population were then scatted by the Galactic bar or spiral structure resonance to intercept Collinder 132's orbit. Without mutual interaction between each population, the three populations are flying by each other currently and will become distinct three groups again in approximately ~50Myr.

description: This research sets out to ascertain the perspectives of Australian teachers on using data to enhance both the quality of teaching and student learning outcomes in the context of music literacy in classroom music education. The aim of the study is to develop an understanding of classroom teachers’ beliefs and perspectives on using data generated from formative assessment of music literacy. The purpose of conducting the study is multifaceted: (i) To understand how perspectives influence teachers’ use of data to guide the teaching and learning process; (ii) to guide professional learning in relation to assessment and (iii) to build assessment capacity that supports learning with a view to enhancing pedagogy, student outcomes and improving participation rates in post-compulsory music education. Whilst existing research into assessment in music education suggests that teachers engage in idiosyncratic, inconsistent and conflicting practices which encompass assessment for learning but do not ensure enhancement of student learning outcomes, a paucity of research has been conducted into teacher perspectives on using student assessment data in classroom music literacy. Inferential coding and thematic analysis of data from qualitative surveys (N=86) and semi-structured interviews (N=8) with participants from across Australia, identified six main themes. Expressed as a set of assessment dilemmas faced by music educators, these dilemmas highlight factors that inhibit music teachers from fully engaging with formative assessment data that could lead to improved pedagogy and learning outcomes in their classrooms. Recommendations from this study have implications for pre-service training, professional learning, teacher assessment identity formation and teacher assessment literacy, through reframing the dilemmatic assessment space as a place of positive growth. Additionally, recommendations identify addressing the Australian curriculum requirements for music education across primary and the first year of secondary education.

description: Very little is yet known regarding the Willmore flow of surfaces with Dirichlet boundary conditions. We consider surfaces with a rotational symmetry as initial data and prove a global existence and convergence result for solutions of the Willmore flow with initial data below an explicit, sharp energy threshold. Strikingly, this threshold depends on the prescribed boundary conditions — it can even be made to be 0. We show sharpness for some critical boundary data by constructing surfaces above this energy threshold so that the corresponding Willmore flow develops a singularity. Finally, a Li–Yau inequality for open curves in is proved.

description: We report neutron inelastic scattering measurements and analysis of the spectrum of magnons propagating within the Fe2O4 bilayers of LuFe2O4. The observed spectrum is consistent with six magnetic modes and a single prominent gap, which is compatible with a single bilayer magnetic unit cell containing six spins. We model the magnon dispersion by linear spin-wave theory and find very good agreement with the domain-averaged spectrum of a spin-charge bilayer superstructure comprising one Fe3+ -rich monolayer and one Fe2+ -rich monolayer. These findings indicate the existence of polar bilayers in LuFe2O4, contrary to recent studies that advocate a charge-segregated non-polar bilayer model. Weak scattering observed below the magnon gap suggests that a fraction of the bilayers contain other combinations of charged monolayers not included in the model. Refined values for the dominant exchange interactions are reported.

description: We identified trajectories of illness uncertainty in chronic hepatitis C patients and examined their association with fatigue levels during 12 months of disease monitoring without treatment (watchful waiting). Sixty-two men and 63 women completed uncertainty and fatigue measures. Groups were formed by uncertainty scores (high, medium, low) at baseline. Baseline fatigue levels were higher in the high uncertainty group than in the medium and low groups. Over time, uncertainty levels did not change. Fatigue levels in the low uncertainty group remained constant, increased in the medium, and decreased in the high groups. Findings suggest that uncertainty and fatigue do not remit spontaneously. Being aware of this may help nurses identify those patients needing support for these two concerns.

description: A method for calculating littoral transport, direct determination of the sediment flux, has been proposed and evaluated. Three sampling stations, located between Virginia Beach and Sandbridge, Virginia, were occupied for a period of thirteen months (September, 1972 to September, 1973). Measurements include velocity of the littoral current, cross-sectional area of the surf zone, and in situ samples of suspended and bottom sediment load. Observations of sea and atmospheric conditions were obtained. Two ways of calculating littoral transport were derived from the same basic method, thus two sets of transport values were generated. Two annual littoral transport values were calculated by use of these figures and regional wave data. The numbers were 1.2 x 1012 and 9.6 x 1011 grams per year or 355,000 and 294,000 cubic yards per year.

Tidal effects on the rate of littoral transport were examined. Transport was greatly affected by changes in cross-sectional area and subsequently in the shape of the zone of littoral transport due to the tidal fluctuations. In addition, beach cusps in conjunction with tidal rise and fall were found to affect the littoral current; cusps were found to retard littoral current at high tide, but were ineffectual at low tide.

It is felt that more work needs to be done in both evaluation of the method and investigation of problems that were encountered.
Quality nursing care for hospitalized patients with advanced illness: Concept development

description: The quality of nursing care as perceived by hospitalized patients with advanced illness has not been examined. A concept of quality nursing care for this population was developed by integrating the literature on constructs defining quality nursing care with empirical findings from interviews of 16 patients with advanced illness. Quality nursing care was characterized as competence and personal caring supported by professionalism and delivered with an appropriate demeanor. Although the attributes of competence, caring, professionalism, and demeanor were identified as common components of quality care across various patient populations, the caring domain increased in importance when patients with advanced illness perceived themselves as vulnerable. Assessment of quality nursing care for patients with advanced illness needs to include measures of patient perceptions of vulnerability.

description: Despite recognition as a significant stressor in childhood cancer, illness-related uncertainty from the perspective of children remains under-studied. We tested a conceptual model of uncertainty, derived from Mishel’s uncertainty in illness theory, in 68 school-aged children and adolescents with cancer. As hypothesized, uncertainty was significantly related to psychological distress, but only one hypothesized antecedent (parental uncertainty) significantly predicted children’s uncertainty. An alternative model incorporating antecedent developmental factors (age and illness-specific expertise) explained 21% of the variance in child uncertainty; controlling for stage of treatment, uncertainty was higher in children with shorter time since diagnosis, older age, lower cancer knowledge, and higher parental uncertainty. These findings provide the foundation for further studies to understand children’s management of uncertainty and its contribution to psychological adjustment to illness.

description: The Higgs-boson decay h -> gamma l+ l- for various lepton states l = (e, mu, tau) is analyzed. The differential decay width and forward-backward asymmetry are calculated as functions of the dilepton invariant mass in a model where the Higgs boson interacts with leptons and quarks via a mixture of scalar and pseudoscalar couplings. These couplings are partly constrained from data on the decays to leptons, h -> l+ l-, and quarks h -> q \bar{q} (where q = (c, b)), while the Higgs couplings to the top quark are chosen from the two-photon and two-gluon decay rates. Nonzero values of the forward-backward asymmetry will manifest effects of new physics in the Higgs sector. The decay width and asymmetry integrated over the dilepton invariant mass are also presented.

description: With professional and home Internet users becoming increasingly concerned with data protection and privacy, the privacy afforded by popular cloud file synchronisation services, such as Dropbox, OneDrive and Google Drive, is coming under scrutiny in the press. A number of these services have recently been reported as sharing information with governmental security agencies without warrants. BitTorrent Sync is seen as an alternative by many and has gathered over two million users by December 2013 (doubling since the previous month). The service is completely decentralised, offers much of the same synchronisation functionality of cloud powered services and utilises encryption for data transmission (and optionally for remote storage). The importance of understanding BitTorrent Sync and its resulting digital investigative implications for law enforcement and forensic investigators will be paramount to future investigations. This paper outlines the client application, its detected network traffic and identifies artefacts that may be of value as evidence for future digital investigations.

description: The purpose of the current study was to examine patterns of state anxiety and pregnancy-specific distress across pregnancy in a diverse sample of women with (n = 113) and without (n = 250) prior miscarriage. For both groups, state anxiety and pregnancy-specific distress were highest in the first trimester and decreased significantly over the course of pregnancy. Compared to women without prior miscarriage, women with prior miscarriage experienced greater state anxiety in the second and third trimesters. Having a living child did not buffer state anxiety in women with a prior miscarriage. Attention to patterns of distress can contribute to delivery of appropriate support resources to women experiencing pregnancy after miscarriage and may help reduce risk for stress-related outcomes.

description: Nursing scholars and healthcare administrators often assume that a more diverse nursing workforce will lead to better patient and nurse outcomes, but this assumption has not been subject to rigorous empirical testing. In a study of nursing units in acute care hospitals, the influence of age, gender, education, race/ethnicity, and perceived value diversity on nurse job satisfaction, nurse intent to stay, and patient satisfaction were examined. Support was found for a negative relationship between perceived value diversity and all outcomes and for a negative relationship between education diversity and intent to stay. Additionally, positive relationships were found between race/ethnicity diversity and nurse job satisfaction as well as between age diversity and intent to stay. From a practice perspective, the findings suggest that implementing retention, recruitment, and management practices that foster a strong shared value system among nurses may lead to better workplace outcomes.

description: Der Einsatz von Feststoffelektrolyten in Lithiumionenbatterien wird als erfolgversprechender Lösungsansatz gesehen, den steigenden Anforderungen an die Energie-dichte und die Sicherheit gerecht zu werden. Eine Herausforderung dabei besteht in der Synthese geeigneter Festkörperelektrolyte mit hoher ionischer Leitfähigkeit und in der Integration dieser Werkstoffe als funktionale Elektrolyte innerhalb des Zellaufbaus. Im Fokus dieser Arbeit stehen dafür oxid-basierte Vertreter der Festkörperelektrolyte. In Bezug auf die Materialentwicklung wird grundlegend untersucht, welche Faktoren für die Derivate der Struktur Li1+xMxTi2-x(PO4)3 einen Einfluss auf die Verdichtung und die ionische Leitfähigkeit haben. Dafür wird systematisch sowohl die Größe als auch die Menge der Substitutionsionen in der Struktur mit M = Al3+, Fe3+ und Sc3+ variiert. Der Herstellungsprozess dieser Materialien wird ausgehend von der Sol-Gel-Synthese, über die Aufbereitung der Pulver, bis hin zu den Sinterbedingungen der keramischen Proben betrachtet und analysiert. Dabei werden die Zusammenhänge zwischen der Mikrostrukturausbildung, dem Anteil an Fremdphasen und den Eigenschaften der Elektrolyte herausgearbeitet. Zusätzlich werden für das ionisch leitfähigste Material Li1,3Al0,3Ti1,7(PO4)3, mit einer ionischen Leitfähigkeit von 1·10-3 S/cm bei Raumtemperatur, in Bezug auf eine skalierbare Produktion geeignete Prozessparameterbereiche aufgezeigt. Im Hinblick auf die funktionelle Integration der oxidischen Elektrolyte in einer Feststoffzelle werden die Prozessparameter für die Formgebung mittels Foliengieß- und Replika-Verfahren für die Materialien Li1,3Al0,3Ti1,7(PO4)3 und Li0,33La0,557TiO3 erarbeitet. Anschließend werden aus den erhaltenen Grünkörperelementen tragfähige Elektrolytstrukturen co-gesintert, die durch Infiltration mit Aktivmaterialien zu Vollzellen komplettiert werden können. Erste Zyklierversuche bestätigen die prinzipielle Funktion der Festkörperbatterien und geben Hinweise für eine effiziente Gestaltung des Aufbaus.

description: Sequent calculus is widely used for formalizing proofs. However, due to the proliferation of data, understanding the proofs of even simple mathematical arguments soon becomes impossible. Graphical user interfaces help in this matter, but since they normally utilize Gentzen's original notation, some of the problems persist. In this paper, we introduce a number of criteria for proof visualization which we have found out to be crucial for analyzing proofs. We then evaluate recent developments in tree visualization with regard to these criteria and propose the Sunburst Tree layout as a complement to the traditional tree structure. This layout constructs inferences as concentric circle arcs around the root inference, allowing the user to focus on the proof's structural content. Finally, we describe its integration into ProofTool and explain how it interacts with the Gentzen layout.

description: Using the Caregiver Reaction Assessment (CRA), we assessed positive reactions and burdens of the caregiving experience among parental caregivers (n = 189) of children scheduled to undergo hematopoietic stem cell transplant. Although widely used in non-parental caregivers, the CRA has not been used in parents of pediatric patients. Reliability (Cronbach’s alpha: .72–.81 vs. .63) and concurrent validity (correlation: .41–.61 vs. .28) were higher for negatively framed than positively framed subscales. Results indicate that the caregiving experience is complex. The parents experienced high caregiver’s esteem and moderate family support, but also negative impacts on finances and schedule, and to a lesser degree, health. Compared to non-parental caregivers, parental caregivers experienced higher esteem and more impact on finances and schedule.

description: Measurement-device-independent quantum key distribution (MDIQKD) protocol is immune to all attacks on detection and guarantees the information-theoretical security even with imperfect single photon detectors. Recently, several proof-of-principle demonstrations of MDIQKD have been achieved. Those experiments, although novel, are implemented through limited distance with a key rate less than 0.1 bps. Here, by developing a 75 MHz clock rate fully-automatic and highly-stable system, and superconducting nanowire single photon detectors with detection efficiencies more than 40%, we extend the secure transmission distance of MDIQKD to 200 km and achieve a secure key rate of three orders of magnitude higher. These results pave the way towards a quantum network with measurement-device-independent security.

description: We present results of the point spread function (PSF) calibration of the hard X-ray optics of the Nuclear Spectroscopic Telescope Array (NuSTAR). Immediately post-launch, NuSTAR has observed bright point sources such as Cyg X-1, Vela X-1, and Her X-1 for the PSF calibration. We use the point source observations taken at several off-axis angles together with a ray-trace model to characterize the in-orbit angular response, and find that the ray-trace model alone does not fit the observed event distributions and applying empirical corrections to the ray-trace model improves the fit significantly. We describe the corrections applied to the ray-trace model and show that the uncertainties in the enclosed energy fraction (EEF) of the new PSF model is < 3% for extraction apertures of R > 60" with no significant energy dependence. We also show that the PSF of the NuSTAR optics has been stable over a period of ~300 days during its in-orbit operation.

description: Over a decade of research in health literacy has provided evidence of strong links between literacy skills of patients and health outcomes. At the same time, numerous studies have yielded insight into efficacious action that health providers can take to mitigate the negative effects of limited literacy. This small study focuses on the adaptation, review and use of two new health literacy toolkits for health professionals who work with patients with two of the most prevalent chronic conditions, arthritis and cardiovascular disease. Pharmacists have a key role in communicating with patients and caregivers about various aspects of disease self-management, which frequently includes appropriate use of medications. Participating pharmacists and staff offered suggestions that helped shape revisions and reported positive experiences with brown bag events, suggestions for approaches with patients managing chronic diseases, and with concrete examples related to several medicines [such as Warfarin©] as well as to common problems [such as inability to afford needed medicine]. Although not yet tested in community pharmacy sites, these publically available toolkits can inform professionals and staff and offer insights for communication improvement.

We find that HSC J0839+0113 resides in the outskirt of an overdense region identified by the r-dropout galaxies at a 4.7 sigma significance level. The projected distance between HSC J0839+0113 and the peak position of the overdense region is 0.4 physical Mpc which is shorter than the typical protocluster radius in this epoch. According to the extended Press Schechter and the light cone models, the HSC J0839+0113-hosted overdense region is expected to evolve into a halo > 10^14 Msun at z=0 with a high probability of >80 %. These findings suggest that HSC J0839+0113 is associated with a protocluster. The HSC J0839+0113 rich-system is the most overdense region of LBGs among the known protoclusters with LBGs in the same cosmic epoch.

description: We present a geometric multigrid solver for the M1 model of radiative transfer without source terms. In radiative hydrodynamics applications, the radiative transfer needs to be solved implicitly because of the fast propagation speed of photons relative to the fluid velocity. The M1 model is hyperbolic and can be discretized with an HLL solver, whose time implicit integration can be done using a nonlinear Jacobi method. One can show that this iterative method always preserves the admissible states, such as positive radiative energy and reduced flux less than 1. To decrease the number of iterations required for the solver to converge, and therefore to decrease the computational cost, we propose a geometric multigrid algorithm. Unfortunately, this method is not able to preserve the admissible states. In order to preserve the admissible state states, we introduce a pseudo-time such that the solution of the problem on the coarse grid is the steady state of a differential equation in pseudo-time. We present preliminary results showing the decrease of the number of iterations and computational cost as a function of the number of multigrid levels used in the method. These results suggest that nonlinear multigrid methods can be used as a robust implicit solver for hyperbolic systems such as the M1 model.

description: We show that a suitable choice for the potential term in the two-dimensional baby Skyrme model yields solitons that have a short-range repulsion and a long-range attraction. The solitons are therefore aloof, in the sense that static multi-soliton bound states have constituents that preserve their individual identities and are sufficiently far apart that tail interactions yield small binding energies. The static multi-soliton solutions are found to have a cluster structure that is reproduced by a simple binary species particle model. In the standard three-dimensional Skyrme model of nuclei, solitons are too tightly bound and are often too symmetric, due to symmetry enhancement as solitons coalesce to form bound states. The aloof baby Skyrmion results endorse a way to resolve these issues and provides motivation for a detailed study of the related three-dimensional version of the Skyrme model.

description: We study modular differential equations for the basic weak Jacobi forms in one abelian variable with applications to the elliptic genus of Calabi--Yau varieties. We show that the elliptic genus of any $CY_3$ satisfies a differential equation of degree one with respect to the heat operator. For a $K3$ surface or any $CY_5$ the degree of the differential equation is $3$. We prove that for a general $CY_4$ its elliptic genus satisfies a modular differential equation of degree $5$. We give examples of differential equations of degree two with respect to the heat operator similar to the Kaneko--Zagier equation for modular forms in one variable. We find modular differential equations of Kaneko--Zagier type of degree $2$ or $3$ for the second, third and fourth powers of the Jacobi theta-series.

The positive-polarity leg also untwists and splits into two parts. The first part runs into the conjugate (negative-polarity) leg, tearing it apart. The second part then converges into the remnant of the conjugate leg, after which both weaken and finally disappear. All these episodes of interaction of oppositely-oriented filament legs are followed by appearance of P-SADs, seen in the on-disk projection to be shaped as loop-tops, along with many weaker SADs. All SADs are preceded by hot supra-arcade downflowing loops. This observed evolution is consistent with the three-dimensional rr-rf (leg-leg) reconnection, where the erupting flux rope reconnects with itself. In our observations, as well as in some models, the reconnection in this geometry is found to be long-lasting. It plays a substantial role in the evolution of the flux rope of the erupting filament and leads to prominent supra-arcade downflows.

description: We present a precise ground-based optical transmission spectrum of the hot-Saturn HATS-5b ($T_{eq} =1025$ K), obtained as part of the ACCESS survey with the IMACS multi-object spectrograph mounted on the Magellan/Baade Telescope. Our spectra cover the 0.5 to 0.9 micron region, and are the product of 5 individual transits observed between 2014 and 2018. We introduce the usage of additional second-order light in our analyses which allows us to extract an "extra" transit light curve, improving the overall precision of our combined transit spectrum. We find that the favored atmospheric model for this transmission spectrum is a solar-metallicity atmosphere with sub-solar C/O, whose features are dominated by H$_2$O and with a depleted abundance of Na and K. If confirmed, this would point to a "clear" atmosphere at the pressure levels probed by transmission spectroscopy for HATS-5b. Our best-fit atmospheric model predicts a rich near-IR spectrum, which makes this exoplanet an excellent target for future follow-up observations with the James Webb Space Telescope, both to confirm this H$_2$O detection and to superbly constrain the atmosphere's parameters.

description: Precision measurements of the Higgs boson properties at the LHC provide relevant constraints on possible weak-scale extensions of the Standard Model (SM). In the context of the Minimal Supersymmetric Standard Model (MSSM) these constraints seem to suggest that all the additional, non-SM-like Higgs bosons should be heavy, with masses larger than about 400 GeV. This article shows that such results do not hold when the theory approaches the conditions for "alignment independent of decoupling", where the lightest CP-even Higgs boson has SM-like tree-level couplings to fermions and gauge bosons, independently of the non-standard Higgs boson masses. The combination of current bounds from direct Higgs boson searches at the LHC, along with the alignment conditions, have a significant impact on the allowed MSSM parameter space yielding light additional Higgs bosons. In particular, after ensuring the correct mass for the lightest CP-even Higgs boson, we find that precision measurements and direct searches are complementary, and may soon be able to probe the region of non-SM-like Higgs boson with masses below the top quark pair mass threshold of 350 GeV and low to moderate values of $\tanβ$.

description: Recently, there has been an increasing demand for deep imaging surveys to investigate the history of the mass assembly of galaxies in detail by examining the remnants of mergers and accretions, both of which have very low surface brightness (LSB). In addition, the nature of star formation in LSB regions, such as galaxy outer disks, is also an intriguing topic in terms of understanding the physical mechanisms of disk evolution. To address these issues, this study conducts a survey project, called the Korea Microlensing Telescope Network (KMTNet) Nearby Galaxy Survey to construct a deep imaging data set of nearby galaxies in the southern hemisphere using KMTNet. It provides deep and wide-field images with a field-of-view of $\sim$12 deg$^2$ for 13 nearby galaxies drawn from the Carnegie-Irvine Galaxy Survey catalog, in optical broadbands ($BRI$) and an H$α$ narrowband. Through a dedicated data reduction, the surface brightness limit in 10$^{\prime\prime}\times10^{\prime\prime}$ boxes was found to reach as deep as $μ_{1σ}\sim29$-31 mag arcsec$^{-2}$ in the optical broadbands and $f_{1σ}\sim1$-$2\times 10^{-18}$ erg s$^{-1}$ cm$^{-2}$ arcsec$^{-2}$ in the H$α$ narrowband. To conclude the paper, several possible scientific applications for this data set are described.

description: We obtain the Arnowitt-Deser-Misner formulation of general relativity in $n$ dimensions ($n \geq 3$) from its either $SO(n-1,1)$ [$SO(n)$] or $SO(n-1)$ Palatini Hamiltonian formulations and vice versa [we recall that $SO(n-1,1)$ [$SO(n)$] requires no gauge fixing whereas $SO(n-1)$ involves the time gauge]. Similarly, the Hamiltonian formulation of general relativity in terms of Ashtekar-Barbero variables can also be directly obtained from the Arnowitt-Deser-Misner Hamiltonian formulation and vice versa, which is an alternative approach to the way followed by Barbero. We give the relevant maps among the phase-space variables and relate the corresponding symplectic structures and the first-class constraints.

description: Hydrogen and helium transmission signals trace the upper atmospheres of hot gas-giant exoplanets, where the incoming stellar extreme ultraviolet and X-ray fluxes are deposited. Further, for the hottest stars, the near-ultraviolet excitation of hydrogen in the Balmer continuum may play a dominant role in controlling the atmospheric temperature and driving photoevaporation. KELT-9 b is the archetypal example of such an environment as it is the hottest gas-giant exoplanet known to date (T$_{eq}$ $\sim$ 4500 K) and orbits an A0V-type star. Studies of the upper atmosphere and escaping gas of this ultra-hot Jupiter have targeted the absorption in the Balmer series of hydrogen (n$_1$ = 2 $\rightarrow$ n$_2$ $>$ 2). Unfortunately, the lowermost metastable helium state that causes the triplet absorption at 108.3 nm is not sufficiently populated for detection. Here, we present evidence of hydrogen absorption in the Paschen series in the transmission spectrum of KELT-9 b observed with CARMENES. Specifically, we focus on the strongest line covered by its NIR channel, Paschen-$β$ at 1282.16 nm (n$_1$ = 3 $\rightarrow$ n$_2$ = 5). The observed absorption shows a contrast of (0.53 $^{+0.12}_{-0.13}$)%, a blueshift of $-$14.8 $^{+3.5}_{-3.2}$ km/s, and a FWHM of 31.9$^{+11.8}_{-8.3}$ km/s. The observed blueshift in the absorption feature could be explained by day-to-night circulation within the gravitationally bound atmosphere or, alternatively, by Paschen-$β$ absorption originating in a tail of escaping gas moving toward the observer as a result of extreme atmospheric evaporation. This detection opens a new window for investigating the atmospheres of ultra-hot Jupiters, providing additional constraints of their temperature structure, mass-loss rates, and dynamics for future modeling of their scorching atmospheres.

description: Four-dimensional asymptotically-free large $N$ gauge theories compactified on $S^3_R \times \mathbb{R}$ have a weakly-coupled confining regime when $R$ is small compared to the strong scale. We compute the vacuum energy of a variety of confining large $N$ non-supersymmetric gauge theories in this calculable regime, where the vacuum energy can be thought of as the $S^3$ Casimir energy. The $N=\infty$ renormalized vacuum energy turns out to vanish in all of the large $N$ gauge theories we have examined, confirming a striking prediction of temperature-reflection symmetry.
