description: From multi-epoch adaptive optics imaging and integral field unit spectroscopy we report the discovery of an expanding and narrowly confined bipolar shell surrounding the helium nova V445 Puppis (Nova Puppis 2000). An equatorial dust disc obscures the nova remnant, and the outflow is characterised by a large polar outflow velocity of 6720 +/- 650 km/s and knots moving at even larger velocities of 8450 +/- 570 km/s. We derive an expansion parallax distance of 8.2 +/- 0.5 kpc and deduce a pre-outburst luminosity of the underlying binary of log L/L_Sun = 4.34 +/- 0.36. The derived luminosity suggests that V445 Puppis probably contains a massive white dwarf accreting at high rate from a helium star companion making it part of a population of binary stars that potentially lead to supernova Ia explosions due to accumulation of helium-rich material on the surface of a massive white dwarf.

description: Mixing processes such as convection, overshooting and rotational mixing have long been known to affect the evolutionary properties of low-mass stars. While modeling a 1.2 Msun star, we encountered a semiconvective region outside the fully convective core, reminiscent of the well-known situation for massive stars. In this study we focus on low-mass stars presenting convective cores and, by applying different prescriptions for the determination of the convective boundaries and using different mixing descriptions for the dynamical processes in the core, we look for the effects of semiconvective mixing in the interior structure of the stars and its observable quantities. With this purpose, we have constructed different sets of evolutionary models using a stellar evolution code (GARSTEC), and analyzed the models looking for imprints of these processes.

description: We calculate the phase diagrams at high temperature of SU(N) gauge theories with massive fermions by minimizing the one-loop effective potential. Considering fermions in the adjoint (Adj) representation at various N we observe a variety of phases when Nf >= 2 Majorana flavours and periodic boundary conditions are applied to fermions. Also the confined phase is perturbatively accessible. For N = 3, we add Fundamental (F) representation fermions with antiperiodic boundary conditions to adjoint QCD to show how the Z(3)-symmetry breaks in the confined phase.

An investigation of sound attentuation by tree stands
Creators: name: Matthews, John Russel
Publisher: name: University of British Columbia
Year: 2011

description: The thesis had two main objectives: namely to provide information on the sound attenuating abilities of tree species of the lower mainland region of British Columbia and to ascertain what stand characteristics cause trees to attenuate sound. After an extensive literature review an experiment was designed to investigate sound attenuation in eighteen tree stands, comprised of four species, at three distances, for eight different sound frequencies. The exerimental work was done during the winter of 1969 and the summer of 1970. Prior to this the tree stands were enumerated and various tree parameters measured. No patterns could be found which significantly correlated the measured stand characteristics with the amount of sound attenuated. Little significant difference was found between the summer and winter attenuations and it was found that stands reacted independently of the season. Tables are presented in the Appendix showing the attenuations for each stand, at each distance and for each frequency. Mean values together with their standard deviations are given for all stands within a species. Suggestions are given for future work on this topic and the implications of the results on various design fields are discussed.
Semi-invariants of symmetric quivers of finite type

Subjects: subject: Representation Theory (math.RT)
subject: FOS: Mathematics

description: Let $(Q,σ)$ be a symmetric quiver, where $Q=(Q_0,Q_1)$ is a finite quiver without oriented cycles and $σ$ is a contravariant involution on $Q_0\sqcup Q_1$. The involution allows us to define a nondegenerate bilinear form $$ on a representation $V$ of $Q$. We shall call the representation orthogonal if $$ is symmetric and symplectic if $$ is skew-symmetric. Moreover we can define an action of products of classical groups on the space of orthogonal representations and on the space of symplectic representations. For symmetric quivers of finite type, we prove that the rings of semi-invariants for this action are spanned by the semi-invariants of determinantal type $c^V$ and, in the case when matrix defining $c^V$ is skew-symmetric, by the Pfaffians $pf^V$.
Timing Signatures of the Internal-Shock Model for Blazars

description: We investigate the spectral and timing signatures of the internal-shock model for blazars. For this purpose, we develop a semi-analytical model for the time-dependent radiative output from internal shocks arising from colliding relativistic shells in a blazar jet. The emission through synchrotron and synchrotron-self Compton (SSC) radiation as well as Comptonization of an isotropic external radiation field are taken into account. We evaluate the discrete correlation function (DCF) of the model light curves in order to evaluate features of photon-energy dependent time lags and the quality of the correlation, represented by the peak value of the DCF. The almost completely analytic nature of our approach allows us to study in detail the influence of various model parameters on the resulting spectral and timing features. This paper focuses on a range of parameters in which the gamma-ray production is dominated by Comptonization of external radiation, most likely appropriate for gamma-ray bright flat-spectrum radio quasars (FSRQs) or low-frequency peaked BL Lac objects (LBLs). In most cases relevant for FSRQs and LBLs, the variability of the optical emission is highly correlated with the X-ray and high-energy (HE: > 100 MeV) gamma-ray emission. Our baseline model predicts a lead of the optical variability with respect to the higher-energy bands by 1 - 2 hours and of the HE gamma-rays before the X-rays by about 1 hour. We show that variations of certain parameters may lead to changing signs of inter-band time lags, potentially explaining the lack of persistent trends of time lags in most blazars.

Renewable energy systems for the Australian Antarctic stations
Creators: name: Brown, CI
Publisher: name: University Of Tasmania
Year: 2023

description: Large quantities of fossil fuels are imported each year to meet the electrical and thermal energy needs of Australia's scientific research stations in Antarctica. A significant part of this fuel, used by diesel generator sets, could be offset through the introduction of renewable energy systems. Reduced fuel usage would lead to savings in transportation time and costs, lower atmospheric emissions and reduce the risk of fuel spills. Research has been conducted to estimate the renewable energy resources of the four Australian Antarctic stations: Casey, Davis and Mawson and Macquarie Island. To achieve this goal, the following procedures were employed: 1. analysis of local meteorological records to identify the wind and solar energy resources; 2. identification and breakdown of station energy demands; and 3. modelling of renewable energy generation and storage systems to estimate potential fuel savings. Analysis of the wind energy potential indicated high resources for Mawson and Macquarie Island, while low resources for Casey and Davis. The solar energy potential was identified as being promising for the continental stations, with high exploitable levels estimated for the summer months. Field work to validate these results was initiated at Casey, including the installation of a 10 kW wind-turbine and a small photovoltaic panel linked with a pyranometer measuring solar insolation levels. Three renewable energy system configurations, envisaged to operate in conjunction with the current diesel generator system, were sized using estimates of each station's electrical energy demand. Configurations investigated include: 1. diesel displacement systems with renewable penetration limited to 40%; 2. renewables in conjunction with power conditioning equipment allowing full penetration; 3. battery storage systems; and 4. hydrogen storage systems. Mawson and Macquarie Island have been identified as the most promising sites. Electrical fuel consumption reductions of 24% and 30% are predicted at these stations for diesel displacement systems with wind turbines rated at 100 kW and 50 kW respectively. Higher fuel consumption reductions of 48% and 75% are predicted in full renewable penetration systems with wind turbines rated at 200 kW and 100 kW. Battery storage systems, beyond a role for power regulation, indicate minimal returns for large investments. A similar result was obtained for a fully integrated renewable energy system involving hydrogen storage. These results demonstrate that renewable energy systems would allow for substantial fuel savings if introduced to the Australian Antarctic Stations.

description: Starting from a previously collected set of tachyon-free closed strings, we search for N=2 minimal model orientifold spectra which contain the standard model and are free of tachyons and tadpoles at lowest order. For each class of tachyon-free closed strings -- bulk supersymmetry, automorphism invariants or Klein bottle projection -- we do indeed find non-supersymmetric and tachyon free chiral brane configurations that contain the standard model. However, a tadpole-cancelling hidden sector could only be found in the case of bulk supersymmetry. Although about half of the examples we have found make use of branes that break the bulk space-time supersymmetry, the resulting massless open string spectra are nevertheless supersymmetric in all cases. Dropping the requirement that the standard model be contained in the spectrum, we find chiral tachyon and tadpole-free solutions in all three cases, although in the case of bulk supersymmetry all massless spectra are supersymmetric. In the other two cases we find truly non-supersymmetric spectra, but a large fraction of them are nevertheless partly or fully supersymmetric at the massless level.

Analytical study of non-linear transport across a semiconductor-metal junction

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: In this paper we study analytically a one-dimensional model for a semiconductor-metal junction. We study the formation of Tamm states and how they evolve when the semi-infinite semiconductor and metal are coupled together. The non-linear current, as a function of the bias voltage, is studied using the non-equilibrium Green's function method and the density matrix of the interface is given. The electronic occupation of the sites defining the interface has strong non-linearities as function of the bias voltage due to strong resonances present in the Green's functions of the junction sites. The surface Green's function is computed analytically by solving a quadratic matrix equation, which does not require adding a small imaginary constant to the energy. The wave function for the surface states is given.
Normal fluid eddies in the thermal counterflow past a cylinder

description: A recent Particle Image Velocimetry (PIV) experiment in He II counterflow around a cylindrical obstacle showed the existence of apparently stationary normal fluid ddies both downstream (at the rear) and upstream (in front) of the cylinder. This rather surprising result does not have an analogue in experimental observations of classical fluid flows. We suggest that the explanation for the apparent stability of such eddies can be provided entirely from the viewpoint of classical fluid dynamics. We also discuss a possible connection between the emergence of the normal fluid eddies and the polarization of the vortex tangle in superfluid.

title: Explaining military, law enforcement and intelligence cooperation between Western states
Creators: name: Lewis, Olivier Rémy Tristan David
Publisher: name: University of St Andrews
Year: 2018

description: This thesis answers the question “Why does security cooperation occur between Western states?”. The basic answer is: “Because most state actors do not want their states to integrate”. In other words, cooperation occurs as a coping mechanism, as an imperfect substitute for integration. But the thesis does not only investigate the reasons for cooperation, what Aristotle called the final cause. The thesis also examines the material, formal and efficient causes of cooperation. Such an unorthodox causal explanation of cooperation is based on a Critical Realist philosophy of social science. The application of this philosophy to the empirical study of International Relation is rare, making this thesis original. Beyond the philosophy of social science, the thesis’ research design, many of the cases, and much of the data are also rarely used. The research design is an embedded multiple-case study. The states studied are the United States of America, France and Luxembourg. Within each state, the embedded subcases are three types of state security organisations: the armed forces, law enforcement and intelligence agencies. Rarely have these three types of security organisations been compared. Similarly, Luxembourg is seldom studied. Comparing different types of states and different types of state security organisations has not only allowed the main research question to be answered. It has also allowed temporal, spatial, national, and functional variation in cooperation to be identified and theorised. The empirical evidence studied includes participant observation (at the North Atlantic Treaty Organisation) and documents (e.g. state policy documents, annual reports by organisations, reports by parliaments and non-governmental organisations, autobiographies, books by investigative journalists, articles by newspapers and magazines). The thesis is also based on a score of elite interviews (e.g. with ambassadors, diplomatic liaisons, ministerial advisors, foreign ministry officers, military commanders, etc.), and the careful study of both declassified and classified archival records.

description: A global study of the electric dipole strength in and below the isovector giant dipole resonance (GDR) is presented for mass numbers A>80. It relies on the recently established remarkably good match between data for the nuclear photo effect to novel photon scattering data covering the region below the neutron emission threshold as well as by average resonance neutron capture (ARC). From the wide energy coverage of these data the correlation of the GDR spreading width with energy can be studied with remarkable accuracy. A clear sensitivity to details of the nuclear shape, i.e. the beta- and gamma-deformations, is demonstrated. Based hereon a new parameterization of the energy dependence of the nuclear electric-dipole strength is proposed which - with only two new parameters - allows to describe the dipole strength in all heavy nuclei with A>80. Although it differs significantly from previous parameterizations it holds for spherical, transitional, triaxial and well deformed nuclei. The GDR spreading width depends in a regular way on the respective resonance energy, but it is independent of the photon energy.

Biology of Typhula erythropus Fr.
Creators: name: Koske, Richard E
Publisher: name: University of British Columbia
Year: 2011

description: The life cycle of Typhula erythropus was studied in the field and. in culture. An attempt was made to correlate observations from both and to explain the behavior of this organism in nature. The effect of temperature, pH, various carbon:nitrogen ratios, and nutrient concentration on mycelial growth, sclerotium formation, and basidiocarp production was examined. Vegetative growth, including sclerotium formation, was favored by temperatures above 10 C, high strength media, and a pH of 4-5. Basidiocarp production was maximal at lower temperatures, on low strength media, at pH 6, and at a low C/N ratio. The conditions for sclerotium germination were determined, and sclerotium viability was investigated. Sclerotia produced at 4 C did not germinate until exposed to 15-20.C. These heat activated sclerotia and sclerotia grown to maturity at 15 C germinated rapidly when incubated at k C on water agar. A low germination rate resulted when sclerotia were incubated at 15 C. The growth zone of T. erythropus basidiocarps is subapical. Expansion of the Typhula fructification occurs in the same manner as that in the common mushroom, Agaricus bisporus. A complex relationship between the particular stage of development of the organism and cultural conditions was evident. The interaction of environmental and nutritional factors was especially obvious during sclerotium formation in culture. T. erythropus appears to be facultatively homothallic. In the absence of a compatible mating strain, all nine monokaryotic isolates became dikaryotic. However, when crossed in all combinations, the monosporic isolates exhibited typical tetrapolar heterothallism. This ambivalence in mating is of rare occurrence in the fungi. Species identification in the genus Typhula is based on such characters as basidiospore measurements, basidiocarp dimensions, coloration, substrate, number of basidiocarps per sclerotium, and sclerotial anatomy. The stability of these features under various conditions has never been tested. Four isolates of T. erythropus were examined in culture, and the constancy of certain taxonomically important characteristics was noted. Basidiospore measurements, sclerotial micro-morphology, and the coloration of basidiocarps arising from sclerotia were stable features in all isolates. Other characteristics were variable.
Aquatic macrophytes of the Macquarie and South Esk Rivers, Tasmania
Creators: name: Chappell, KJ
Publisher: name: University Of Tasmania
Year: 2023

description: Aquatic macrophytes are the flowering plants and larger algae growing submerged in or emerging from water. Macrophytes are an essential component of riverine ecosystems: they produce oxygen, filter out sediments and pollutants and provide habitat and food sources for invertebrates, fish and mammals. The Macquarie and South Esk Rivers in Tasmania are the largest rivers of the northern central plain, and are unique in Tasmania in having long stretches of relatively stable and abundant macrophytic vegetation along their mid- to lower reaches. The macrophyte communities of the mid- to lower reaches of the two rivers are described by classification into groups with similar species composition. Significant environmental variation between groups is determined. Depth, substrate type and distance upstream are the environmental factors most strongly associated with variation between the distribution of individual species/species assemblages. Distance upstream, percentage shading, river form, stream width, substrate type and bank height are the factors most strongly associated with variation between groups of sites. Bank vegetation type, distance upstream, percentage shading, level of stock damage and stream width are found to be the environmental factors most strongly associated with differences in richness and diversity. Percentage shading and bank vegetation type are the factors most strongly associated with differences in cover. The two rivers are found to differ significantly in percentage cover and total species richness. The associated environmental factors that vary significantly between the rivers are percentage shading, bank height, bank vegetation type, level of stock damage and stream width. The species rich and abundant macrophyte communities in the mid-reaches of the Macquarie River and in some parts of the South Esk are found to have high conservation value. A vulnerable marginal species, Persicaria decipiens, is also of high conservation value. Willow infestation and changes to flow regimes or water quality are seen as being the greatest threats to these communities. The importance of management of stock access to river edges and the potential value of buffer zones are discussed.
Optimal rates of convergence for estimating the null density and proportion of nonnull effects in large-scale multiple testing

description: An important estimation problem that is closely related to large-scale multiple testing is that of estimating the null density and the proportion of nonnull effects. A few estimators have been introduced in the literature; however, several important problems, including the evaluation of the minimax rate of convergence and the construction of rate-optimal estimators, remain open. In this paper, we consider optimal estimation of the null density and the proportion of nonnull effects. Both minimax lower and upper bounds are derived. The lower bound is established by a two-point testing argument, where at the core is the novel construction of two least favorable marginal densities $f_1$ and $f_2$. The density $f_1$ is heavy tailed both in the spatial and frequency domains and $f_2$ is a perturbation of $f_1$ such that the characteristic functions associated with $f_1$ and $f_2$ match each other in low frequencies. The minimax upper bound is obtained by constructing estimators which rely on the empirical characteristic function and Fourier analysis. The estimator is shown to be minimax rate optimal. Compared to existing methods in the literature, the proposed procedure not only provides more precise estimates of the null density and the proportion of the nonnull effects, but also yields more accurate results when used inside some multiple testing procedures which aim at controlling the False Discovery Rate (FDR). The procedure is easy to implement and numerical results are given.

description: We show that a Dicke-type pseudo-hermitian Hamiltonian undergoes quantum phase transition by mapping it to the "Dressed Dicke Model" through a similarity transformation. We find the positive-definite metric in the Hilbert space of the pseudo-hermitian Hamiltonian so that it is unitary and allows a consistent quantum description. Further, we obtain the limit in which the pseudo-hermitian Hamiltonian is exactly solvable.

description: Patterned surfaces with large effective slip lengths, such as super-hydrophobic surfaces containing trapped gas bubbles, have the potential to greatly enhance electrokinetic phenomena. Existing theories assume either homogeneous flat surfaces or patterned surfaces with thin double layers (compared to the texture correlation length) and thus predict simple surface-averaged, isotropic flows (independent of orientation). By analyzing electro-osmotic flows over striped slip-stick surfaces with arbitrary double-layer thickness, we show that surface anisotropy generally leads to a tensorial electro-osmotic mobility and subtle, nonlinear averaging of surface properties. Interestingly, the electro-osmotic mobility tensor is not simply related to the hydrodynamic slip tensor, except in special cases. Our results imply that significantly enhanced electro-osmotic flows over super-hydrophobic surfaces are possible, but only with charged liquid-gas interfaces.

description: Diffusive shock acceleration (DSA) at relativistic shocks is expected to be an important acceleration mechanism in a variety of astrophysical objects including extragalactic jets in active galactic nuclei and gamma ray bursts. These sources remain strong and interesting candidate sites for the generation of ultra-high energy cosmic rays. In this paper, key predictions of DSA at relativistic shocks that are salient to the issue of cosmic ray ion and electron production are outlined. Results from a Monte Carlo simulation of such diffusive acceleration in test-particle, relativistic, oblique, MHD shocks are presented. Simulation output is described for both large angle and small angle scattering scenarios, and a variety of shock obliquities including superluminal regimes when the de Hoffman-Teller frame does not exist. The distribution function power-law indices compare favorably with results from other techniques. They are found to depend sensitively on the mean magnetic field orientation in the shock, and the nature of MHD turbulence that propagates along fields in shock environs. An interesting regime of flat spectrum generation is addressed, providing evidence for its origin being due to shock drift acceleration. The impact of these theoretical results on gamma-ray burst and blazar science is outlined. Specifically, Fermi gamma-ray observations of these cosmic sources are already providing significant constraints on important environmental quantities for relativistic shocks, namely the frequency of scattering and the level of field turbulence.

description: We report on changes of the cyclotron resonance energies of the recurrent transient pulsar, X0331+53 (V0332+53). The whole RXTE data acquired in the 2004-2005 outburst were utilized. The 3-80 keV source luminosity varied between 1.7x10^36 and 3.5x10^38 ers/s, assuming a distance of 7 kpc. We confirmed that the fundamental cyclotron resonance energy changed from ~22 to ~27 keV in a clear anti-correlation to the source luminosity, and without any hysteresis effects between the rising and declining phases of the outburst. In contrast, the second harmonic energy changed from ~49 to ~54 keV, implying a weaker fractional change as a function of the luminosity. As a result, the observed resonance energy ratio between the second harmonic and the fundamental was ~2.2 when the source was most luminous, whereas the ratio decreased to the nominal value of 2.0 at the least luminous state. Although the significance of this effect is model dependent, these results suggest that the fundamental and second harmonic resonances represent different heights in the accretion column, depending on the mass accretion rate.

The Tasmania non-ferrous mineral industry
Creators: name: Brinsmead, T. G
Publisher: name: University Of Tasmania
Year: 2023

description: The following is an attempted economic study of Tasmania's principal non-ferrous mineral industries comprising copper, tin, silver-lead and zinc, which are surveyed separately and prefaced by an historical outline of the chief mining fields relating to each. The historical outlines have been included because they indicate the economic problems awaiting solution, and in addition they testify to the wisdom or otherwise of certain policies, and the applicability of specific principles. The economic survey here undertaken was prompted by a spirit of enquiry arising out of a three years' close association with Tasmania's west Coast mining fields. The instability of mining, with its derelict capital, annihilation of whole towns and impermanence in community life generally,first aroused this enquiry. The method adopted has been to collect as many facts as possible pertaining to the subject, and from this data, make a study of the structure and problems of each industry separately In the final analysis, the thesis is permitted to emphasise its most obvious conclusions,and provide a brief practical proposition as an answer to them. The base year taken for copper is 1933, and although this was a very unfavourable year for most industries, no serious objection can be taken to it here, for the copper industry was a steadily expanding one. Whore obtainable, I have tried to make 1928 the base year on which to plot graphs, because this year was generally recognised as a most favourable one. All statistics are authentic, except where marked \Approximate\" and there they are provided only on the most reliable evidence. Companies facing the biggest problems such as the Mt. Lyell Mining and Railway Company Limited proved the most fruitful in my canvass for information while those whose problems were relatively small were the least willing and the most suspicious."

description: The Laser Interferometer Space Antenna (LISA) defines new demands on data analysis efforts in its all-sky gravitational wave survey, recording simultaneously thousands of galactic compact object binary foreground sources and tens to hundreds of background sources like binary black hole mergers and extreme mass ratio inspirals. We approach this problem with an adaptive and fully automatic Reversible Jump Markov Chain Monte Carlo sampler, able to sample from the joint posterior density function (as established by Bayes theorem) for a given mixture of signals "out of the box'', handling the total number of signals as an additional unknown parameter beside the unknown parameters of each individual source and the noise floor. We show in examples from the LISA Mock Data Challenge implementing the full response of LISA in its TDI description that this sampler is able to extract monochromatic Double White Dwarf signals out of colored instrumental noise and additional foreground and background noise successfully in a global fitting approach. We introduce 2 examples with fixed number of signals (MCMC sampling), and 1 example with unknown number of signals (RJ-MCMC), the latter further promoting the idea behind an experimental adaptation of the model indicator proposal densities in the main sampling stage. We note that the experienced runtimes and degeneracies in parameter extraction limit the shown examples to the extraction of a low but realistic number of signals.

description: We have measured the radiative lifetimes of ns, np and nd Rydberg states of rubidium in the range 28 < n < 45. To enable long-lived states to be measured, our experiment uses slow-moving Rb atoms in a magneto-optical trap (MOT). Two experimental techniques have been adopted to reduce random and systematic errors. First, a narrow-bandwidth pulsed laser is used to excite the target Rydberg state, resulting in minimal shot-to-shot variation in the initial state population. Second, we monitor the target state population as a function of time delay from the laser pulse using a short-duration, millimetre-wave pulse that is resonant with a one- or two-photon transition. We then selectively field ionize the monitor state, and detect the resulting electrons with a micro-channel plate. This signal is an accurate mirror of the target state population, and is uncontaminated by contributions from other states which are populated by black body radiation. Our results are generally consistent with other recent experimental results obtained using a less sensitive method, and are also in excellent agreement with theory.

description: We measured the Raman and the Infrared phonon spectrum of SmFeAsO polycrystalline samples. We also performed Density Functional Theory calculations within the pseudopotential approximation to obtain the structural and dynamical lattice properties of both the SmFeAsO and the prototype LaFeAsO compounds. The measured Raman and Infrared phonon frequencies are well predicted by the optical phonon frequencies computed at the Gamma point, showing the capability of the employed ab-initio methods to describe the dynamical properties of these materials. A comparison among the phonon frequencies of different oxypnictides suggests a possible role of the high frequency phonons in the pairing mechanism leading to superconductivity in these materials.

description: We have measured the spectral energy distribution (SED) of the host galaxy of the z_s=1.7 gravitationally lensed quasar SDSS J1004+4112 from 0.44-8.0 micron (0.16-3.0 micron in the rest frame). The large angular extent of the lensed images and their separation from the centralgalaxy of this cluster lens allows the images to be resolved even with the Spitzer Space Telescope. Based on the SED, the host galaxy is a mixture of relatively old and intermediate age stars with an inferred stellar mass of log(M_stars/M_sun)=11.09+/-0.28 and a star formation rate of log(Mdot/1 M_sun per yr)=1.21+/-0.26. Given the estimated black hole mass of M_BH ~10^8.6 M_sun from locally-calibrated correlations of black hole masses with line widths and luminosities, the black hole represents a fraction log(M_BH/M_stars) = -2.49+/-0.28 of the stellar mass and it is radiating at 0.24+/-0.05 of the Eddington limit. The ratio of the host stellar mass to the black hole mass is only marginally consistent with the locally observed ratio.
