description: Performing accurate large eddy simulations in compressible, turbulent magnetohydrodynamics is more challenging than in non-magnetized fluids due to the complex interplay between kinetic, magnetic and internal energy at different scales. Here we extend the sub-grid-scale gradient model, so far used in the momentum and induction equations, to account also for the unresolved scales in the energy evolution equation of a compressible ideal MHD fluid with a generic equation of state. We assess the model by considering box simulations of the turbulence triggered across a shear layer by the Kelvin-Helmholtz instability, testing cases where the small-scale dynamics cannot be fully captured by the resolution considered, such that the efficiency of the simulated dynamo effect depends on the resolution employed. This lack of numerical convergence is actually a currently common issue in several astrophysical problems, where the integral and fastest-growing-instability scales are too far apart to be fully covered numerically. We perform a-priori and a-posteriori tests of the extended gradient model. In the former, we find that, for many different initial conditions and resolutions, the gradient model outperforms other commonly used models in terms of correlation with the residuals coming from the filtering of a high-resolution run. In the second test, we show how a low-resolution run with the gradient model is able to quantitatively reproduce the evolution of the magnetic energy (the integrated value and the spectral distribution) coming from higher-resolution runs. This extension is the first step towards the implementation in relativistic magnetohydrodynamics.

description: We report on a spectro-polarimetric analysis of four southern Ultra-Luminous Infrared Galaxies (ULIRGs), aimed at constraining the presence of hidden broad AGN lines. For IRAS 19254--7245 ({\sl The Superantennae}) we find evidence for a significant level of polarized light in the H$α$ line with FWHM$>$2300 km/s. Some degree of polarization is also detected in IRAS 20551-4250, though with lower significance. In the two other sources (IRAS 20100--4156 and IRAS 22491--1808) no polarized signals are detected. Although it is unclear from the present data if the origin of polarization is due to reflected light from an AGN or more simply to dichroic transmission by a dust slab, we find interesting correlation between the presence of polarized components in the optical spectra and independent evidence for AGN emissions in hard X-rays and the far-IR.

Pseudochetoneura

description: Pseudochetoneura gen. nov.
 Type species. Pseudochetoneura otongensis sp. nov., here designated.
 Diagnosis. Two ocelli. Antennae with 14 flagellomeres. Flagellomeres short, cylindrical, at most as long as wide. Mouthparts strongly reduced, palpus with only one segment. Compound eyes relatively narrow in lateral view. Both mediotergite and laterotergite bare. Mediotergite without distinct membranous subscutellar area. Wing unmarked, slightly darkened, membrane covered with microtrichia. Radial veins and CuA 2 dark and strong, the other veins lighter. C produced beyond R 5 to about half the distance between the tips of R 5 and M 1. Vein Sc ending free, apically obsolete, reaching to the level of Rs. R-M fusion short but distinct. Crossvein Rs relatively short and almost vertical. M-Cu connection and basal part of M indistinct. The stem of M-fork long. Cu-fork with point of furcation at the base of wing. CuA 1 weaker, CuA 2 strong, distinctly downcurved towards the tip. CuP relatively long and strong, A 1 short, distally weak. Legs without special tibial organs. Tibial setae irregularly arranged. Abdomen distinctly bent downwards. Male terminalia with gonocoxites fused only basally. Gonostylus relatively large, about as long as wide, with rounded apical projection. Aedeagal complex large, its laterally compressed plate extending into segment 7. Tergite 9 short, transverse, three times as broad as long.
 Differential diagnosis. The new genus is most similar to the Oriental genera Chetoneura and Microkeroplatus Ševčík & Papp, 2009, from which it differs mainly in the length of male antennae (only 3 times as long as head), shape of flagellomeres (these are not S-shaped or anteriorly prolonged), stronger reduction of mouthparts (reduced labella, one palpomere without palpifer), shorter wings (ratio of length to width only 2.2), wing venation (Sc ending free, R 1 reaching well beyond the point of furcation of M), distinctly bent abdomen, and peculiar male terminalia (remarkable aedeagal complex, short tergite 9). The habitus photograph of Chetoneura cavernae Colless, 1962 is presented here for comparison (Fig. 6) to supplement the description by COLLESS (1962).
 Etymology. The name is modified from Chetoneura, a related genus, by the Greek prefix pseudo-, referring to their similarity. Gender is feminine.

description: One of the key questions in the study of relativistic jets is how magnetic reconnection occurs and whether it can effectively accelerate electrons in the jet. We performed 3D particle-in-cell (PIC) simulations of a relativistic electron-proton jet of relatively large radius that carries a helical magnetic field. We focussed our investigation on the interaction between the jet and the ambient plasma and explore how the helical magnetic field affects the excitation of kinetic instabilities such as the Weibel instability (WI), the kinetic Kelvin-Helmholtz instability (kKHI), and the mushroom instability (MI). In our simulations these kinetic instabilities are indeed excited, and particles are accelerated. At the linear stage we observe recollimation shocks near the center of the jet. As the electron-proton jet evolves into the deep nonlinear stage, the helical magnetic field becomes untangled due to reconnection-like phenomena, and electrons are repeatedly accelerated as they encounter magnetic-reconnection events in the turbulent magnetic field.

description: Shared quantum correlations find application in a wide range of modern quantum information protocols. This thesis presents several optical experiments towards the improved certification of shared quantum correlations, using photonic qubits. The first experiment demonstrates the Einstein–Podolsky–Rosen (EPR) steering effect with no detection loophole. Polarisation–entangled photon pairs generated in a Sagnac interferometer were used to test new loss–tolerant EPR steering inequalities. To test the robustness of the loss–tolerant EPR steering nequalities, a transmission loss of −4.3dB was introduced using a 1km optical fibre loop, finding inequality violations for n = 10 and n = 16 measurement settings with no detection loophole (equating to a total loss of 87%). The findings demonstrate how the new loss–tolerant protocols can be used to certify the EPR steering effect for arbitrarily high losses, and may find application in one–sided device–independent quantum key distribution protocols. The second experiment introduces EPR steering in the context of an EPR steering game. The rules of the game allow for certification of shared quantum correlations via EPR steering inequalites without requiring trust in devices or parties external to a quantum referee. In particular, the experiment successfully demonstrates EPR steering in a measurement–device independent framework; a framework which has typically been accessible only through Bell inequality violations. The findings suggest the possibility for quantum–refereed one–sided device–independent quantum key distribution protocols.

description: Objective: To describe the prevalence and costs of anxiety and depression among moderate-to-severe psoriasis (PsO) patients in a commercially-insured US population. Methods: The IBM MarketScan Commercial database was used to select adults with moderate-to-severe PsO (≥1 PsO diagnosis and ≥1 systemic or biologic medication) within each calendar year from 2014 to 2016. Adults with no diagnosis of PsO or similar disorders were randomly selected (2014–2016) and matched 1:1 to PsO patients to compare the prevalence of anxiety and depression each year. Moderate-to-severe PsO patients identified in 2014 with continuous enrollment through 2015 were stratified into those with treated anxiety and/or depression (≥1 anxiety or depression diagnosis plus any anxiolytics, antidepressants, or antipsychotics within 30 days) vs those without anxiety/depression, and then matched 1:1 to determine the incremental burden of treated anxiety/depression among PsO patients. All-cause and PsO-related healthcare costs were compared between the matched cohorts using generalized linear models. Results: In total, 69,644 matched PsO and non-PsO patients were identified in 2014, 61,478 in 2015, and 66,880 in 2016. The prevalence of anxiety/depression among PsO patients increased more than for matched controls, from 18.2% vs 12.2% in 2014 (p p p p p p Conclusions: The prevalence of psychiatric disorders is higher among PsO patients than the general population, and the incremental burden of treated anxiety/depression is substantial. Further research is needed, but PsO treatments that improve psychiatric symptoms such as anxiety/depression may benefit patients and reduce their economic burden.

description: In this thesis I argue that negative attributions mediate between attachment insecurity and relationship outcomes. Using a sample of 59 couples the well-documented association between attachment insecurity and relationship satisfaction was replicated. I then tested whether this association was mediated by attributions for hypothetical behaviour for a real partner and a hypothetical potential partner. Attributions for real partner behaviour did mediate between insecure attachment and relationship satisfaction, but not attributions for a potential partner. It was further hypothesised that an association would exist between couple communication and attachment insecurity, which would be mediated by negative attributions. Couples completed two ten-minute problem-solving discussions and participated in a video-mediated recall process, providing a measure of attributions for real events with their current partner. Results supported the hypotheses for self-reported, but not observed, communication. It was concluded that the association between attachment and attributions does not represent a consistent cognitive processing bias, but rather a relationship-specific phenomena. Future research directions were proposed to investigate mediation from a long-term perspective and the therapeutic implications of these findings were discussed.

description: The paper discusses the efficiency of the classical BiCGStab method and several of its modifications for solving systems with multiple right-hand side vectors. These iterative methods are widely used for solving systems with large sparse matrices. The paper presents execution time analytical model for the time to solve the systems. The BiCGStab method and several modifications including the Reordered BiCGStab and Pipelined BiCGStab methods are analyzed and the range of applicability for each method providing the best execution time is highlighted. The results of the analytical model are validated by the numerical experiments and compared with results of other authors. The presented results demonstrate an increasing role of the vector operations when performing simulations with multiple right-hand side vectors. The proposed merging of vector operations allows to reduce the memory traffic and improve performance of the calculations by about 30%.

Towards an Understanding of the Resolution Dependence of Core-Collapse Supernova Simulations

description: Using our new state-of-the-art core-collapse supernova (CCSN) code Fornax, we explore the dependence upon spatial resolution of the outcome and character of three-dimensional (3D) supernova simulations. For the same 19-M$_{\odot}$ progenitor star, energy and radial binning, neutrino microphysics, and nuclear equation of state, changing only the number of angular bins in the $θ$ and $ϕ$ directions, we witness that our lowest resolution 3D simulation does not explode. However, when jumping progressively up in resolution by factors of two in each angular direction on our spherical-polar grid, models then explode, and explode slightly more vigorously with increasing resolution. This suggests that there can be a qualitative dependence of the outcome of 3D CCSN simulations upon spatial resolution. The critical aspect of higher spatial resolution is the adequate capturing of the physics of neutrino-driven turbulence, in particular its Reynolds stress. The greater numerical viscosity of lower-resolution simulations results in greater drag on the turbulent eddies that embody turbulent stress, and, hence, in a diminution of their vigor. Turbulent stress not only pushes the temporarily stalled shock further out, but bootstraps a concomitant increase in the deposited neutrino power. Both effects together lie at the core of the resolution dependence we observe.

Radiation Front Sweeping the Ambient Medium of Gamma-Ray Bursts
Creators: name: Beloborodov, Andrei M.
Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Gamma-ray bursts (GRBs) are emitted by relativistic ejecta from powerful cosmic explosions. Their light curves suggest that the gamma-ray emission occurs at early stages of the ejecta expansion, well before it decelerates in the ambient medium. If so, the launched gamma-ray front must overtake the ejecta and sweep the ambient medium outward. As a result a gap is opened between the ejecta and the medium that surfs the radiation front ahead. Effectively, the ejecta moves in a cavity until it reaches a radius R_{gap}=10^{16}E_{54}^{1/2} cm where E is the isotropic energy of the GRB. At R=R_{gap} the gap is closed, a blast wave forms and collects the medium swept by radiation. Further development of the blast wave is strongly affected by the leading radiation front: the front plays the role of a precursor where the medium is loaded with e+- pairs and preaccelerated just ahead of the blast. It impacts the emission from the blast at R < R_{load}=5R_{gap} (the early afterglow). A spectacular observational effect results: GRB afterglows should start in optical/UV and evolve fast (< min) to a normal X-ray afterglow. The early optical emission observed in GRB 990123 may be explained in this way. The impact of the front is especially strong if the ambient medium is a wind from a massive progenitor of the GRB. In this case three phenomena are predicted: (1) The ejecta decelerates at R

description: Literary and linguistic prosody principles can provide a wealth of creative strategies within songwriting. Very often, these strategies are part of the songwriter’s innate, internal process of creation, or when consciously employed are so embedded in the work that they may not be immediately apparent to a listener. This research project attempts to shed light on some of the ways prosody impacts a final work, or body of work, guided by the primary research question: In what ways does literary and linguistic prosody inform songwriting? The vehicle for this inquiry has been my own songwriting practice; a driver has been my ongoing commitment as a musician of over 30 years to continually hone my own songwriting skills and to understand the craft. Interpreting and reflecting on extensive literature on literary and linguistic prosody has assisted me to highlight the relevance of these areas to my practice. Early in the project I noted discussions about the duality of prosody and developed a personal maxim which has helped to shape this inquiry, that words make the music and music makes the words. Framed by an overarching constructivist worldview, the project adopts a mixed method research design to interrogate and test this maxim. Elements of this research design include artistic research, action research, interviews, participant observation and musical analysis. The quest to answer my primary, and subsequently identified secondary research questions, has generated a network of themes which I hope will make a contribution to the growing theory and understanding of prosody. More practically, I intend that a detailed analysis of songwriting and composing techniques will offer some guidelines and strategies for my students, and fellow singer-songwriter artists. Finally, I offer my own example of the application of prosody in the CD of original work created to accompany this exegesis. This research album titled Beginner’s Mind will, I hope, illustrate my final opinions and decisions reached by the work within the research project about the centrality of prosody in songwriting – in all its forms.

description: We report on our findings of the bright, pulsating, helium atmosphere white dwarf GD 358, based on time-resolved optical spectrophotometry. We identify 5 real pulsation modes and at least 6 combination modes at frequencies consistent with those found in previous observations. The measured Doppler shifts from our spectra show variations with amplitudes of up to 5.5 km/s at the frequencies inferred from the flux variations. We conclude that these are variations in the line-of-sight velocities associated with the pulsational motion. We use the observed flux and velocity amplitudes and phases to test theoretical predictions within the convective driving framework, and compare these with similar observations of the hydrogen atmosphere white dwarf pulsators (DAVs). The wavelength dependence of the fractional pulsation amplitudes (chromatic amplitudes) allows us to conclude that all five real modes share the same spherical degree, most likely, l=1. This is consistent with previous identifications based solely on photometry. We find that a high signal-to-noise mean spectrum on its own is not enough to determine the atmospheric parameters and that there are small but significant discrepancies between the observations and model atmospheres. The source of these remains to be identified. While we infer T_eff=24kK and log g~8.0 from the mean spectrum, the chromatic amplitudes, which are a measure of the derivative of the flux with respect to the temperature, unambiguously favour a higher effective temperature, 27kK, which is more in line with independent determinations from ultra-violet spectra.

description: The correlation-driven Mott transition is commonly characterized by a drop in resistivity across the insulator-metal phase boundary; yet, the complex permittivity provides a deeper insight into the microscopic nature. We investigate the frequency- and temperature-dependent dielectric response of the Mott insulator $κ$-(BEDT-TTF)$_{2}$-Cu$_2$(CN)$_3$ when tuning from a quantum spin liquid into the Fermi-liquid state by applying external pressure and chemical substitution of the donor molecules. At low temperatures the coexistence region at the first-order transition leads to a strong enhancement of the quasi-static dielectric constant $ε_1$ when the effective correlations are tuned through the critical value. Several dynamical regimes are identified around the Mott point and vividly mapped through pronounced permittivity crossovers. All experimental trends are captured by dynamical mean-field theory of the single-band Hubbard model supplemented by percolation theory.

description: In this paper, we investigate the effect of a wide binary companion of the lens on the astrometric behavior of Galactic gravitational microlensing events and compare it to the effect on the photometric behavior. We find that the wide binary companion of the lens can affect the centroid motion of images substantially even if the corresponding light curve appears to be the one of a standard single point-mass lens event. The relatively significant effect of the wide binary lens on the astrometric lensing behavior, on one side, calls for careful consideration of the lens binarity in analyzing the future astrometric lensing data. On the other side, larger astrometric effect of the companion makes astrometric lensing an efficient method to detect binary lenses over a broad range of separations.

description: The black-hole binary LMC X-3 is known to be variable on time scales of days to years. We investigate X-ray and ultraviolet variability in the system as a function of the 1.7 day binary phase using a 6.4 day observation with the Rossi X-ray Timing Explorer (RXTE) from December 1998. An abrupt 14% flux decrease, lasting nearly an entire orbit, is followed by a return to previous flux levels. This behavior occurs twice, at nearly the same binary phase, but it is not present in consecutive orbits. When the X-ray flux is at lower intensity, a periodic amplitude modulation of 7% is evident in data folded modulo the orbital period. The higher intensity data show weaker correlation with phase. This is the first report of X-ray variability at the orbital period of LMC X-3. Archival RXTE observations of LMC X--3 during a high flux state in December 1996 show similar phase dependence. An ultraviolet light curve obtained with the High Speed Photometer aboard the Hubble Space Telescope shows orbital modulation consistent with that in the optical, caused by the ellipsoidal variation of the spatially deformed companion. The X-ray spectrum of LMC X-3 can be acceptably represented by a phenomenological disk-black-body plus a power law. Changes in the spectrum of LMC X-3 during our observations are compatible with earlier observations during which variations in the 2-10 keV flux are tracked closely by the disk geometry spectral model parameter.

description: The rate of energy transfer from ion projectiles onto the electrons of a solid target is hard to determine experimentally in the velocity regime between the adiabatic limit and the Bragg peak. First-principles simulations have lately offered relevant new insights and quantitative information for prototypical homogeneous materials. Here we study the influence of structural anisotropy on electronic stopping power with time-dependent density functional theory simulations of a hydrogen projectile in graphite. The projectile traveled at a range of angles and impact parameters for velocities between 0.1 and 1.4 a.u., and the electronic stopping power was calculated for each simulation. After validation with average experimental data, the anisotropic crystal structure was found to have a strong influence on the stopping power, with a difference between simulations parallel and perpendicular to the graphite plane of up to 25%, more anisotropic than expected based on previous work. The velocity dependence at low velocity displays clear linear behavior in general, except for projectiles traveling perpendicular to graphitic layers, for which a threshold-like behavior is obtained. For projectiles traveling along graphitic planes metallic behaviour is observed with a change of slope when the projectile velocity reaches the Fermi velocity of the electrons.

description: Quantum entanglement obscures the notion of local operations; there exist quantum states for which all local actions on one subsystem can be equivalently realized by actions on another. We characterize the states for which this fundamental property of entanglement does and does not hold, including multipartite and mixed states. Our results lead to a method for quantifying entanglement based on operational symmetries and has connections to quantum steering, envariance, the Reeh-Schlieder theorem, and classical entanglement.

Thermal Comptonization and Disk Thermal Reprocessing in NGC 3516
Creators: name: Chiang, James

Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present an application of the thermal Comptonization/disk reprocessing model recently proposed by Zdziarski, Lubiński, & Smith. We show that the absence of strong optical variations in the presence of strong concurrent X-ray variations, similar to those found by HST/RXTE monitoring observations of NGC 3516, can be explained by changing the geometry of the Comptonizing plasma rather than the accretion disk itself. The total X-ray luminosity of the Comptonizing plasma must decrease as its spatial extent increases. In contrast, the disk inner radius must be roughly fixed in order not to produce optical/ultraviolet color variations stronger than observed. By including emission due to internal viscous dissipation in the disk, we can roughly match the optical and X-ray flux levels and variability amplitudes seen from NGC 3516 during the HST/RXTE campaign.

title: Dyadic Decision-Making: A Grounded Theory of Top Level Team Decision and Exchange Behavior
Creators: name: Rowland, Paul
Publisher: name: Griffith University
Year: 2007
Subjects: subject: Dyadic decision making
subject: Organisational behavior

description: This dissertation is a report on a program of research study about top level behaviour in the context of organisational relationships. The aims of the research study were two-fold. First, the research sought to make an original contribution to the theory about the effect of top level team decision-making behaviour on exchange relationships between organisational units. Second, in response to a call in the extant literature for greater understanding of exchange behaviour in an applied sense within organisations, the current program of research also sought to explore the contribution that a grounded theory-based methodology could make to the understanding of this phenomenon. The broad substantive setting for the research was knowledge industries, and the specific focus was on large Australian universities. A basic social process of Dyadic Decision-Making emerged from this program of research. This basic social process was found to be central to top level team behaviour during decisionmaking, especially where matters concerned other organisational areas. This research identifies that top level team decision-making activity serves the practical purpose of dealing with strategic and operational issues at the organisational unit level. Moreover, the current program of study finds that top level team decision-making serves an important role in shaping the longer term exchange relationships which organisational units develop between each other. In this context, Dyadic Decision-Making represents a basic social process by which top level teams build exchange dyads between their own, and other organisational units. This research program identifies that the level of emphasis on relationship considerations within top level teams is a key determinant of decision-making behaviour and, by extension, the messages which organisational units send about the way they wish to exchange with other organisational units. For team leaders, relationship emphasis manifests in the leadership style which they adopt within their teams. For team members, relationship emphasis manifests in the perspectives they exhibit during team discussions, and is shaped inter alia by the definition of their day to day job roles.

description: We present high angular resolution (~0.5") 10 and 18 micron images of the region around G29.96-0.02 taken from the Gemini North 8-m telescope using the mid-infrared imager and spectrometer OSCIR. These observations were centered on the location of a group of water masers, which delineate the site of a hot molecular core believed to contain an extremely young, massive star. We report here the direct detection of a hot molecular core at mid-infrared wavelengths at this location. The size and extent of the core at 18 microns appears to be very similar to the morphology as seen in integrated NH3 maps. However, our observations indicate that the mid-infrared emission may not be exactly coincident with the NH3 emission.

title: Financial Hardship and Strain Predict Student Well-being: The Importance of Socialisation, Social Support and Young Adult Roles
Creators: name: Watson, Stuart James
Publisher: name: Griffith University
Year: 2016
Subjects: subject: University students, Wellbeing
subject: University students, Financial conditions

description: For most tertiary students, participation in higher education occurs directly after high school, when they are navigating a dynamic, and potentially stressful, pathway to adulthood. The years spent studying are often the most cash-strapped for young adults, when economising heavily and sometimes going without are normative experiences. Australian university students report substantial hardship, regularly cutting back their spending on basic necessities and simple life pleasures (Bexley, Daroesman, Arkoudis & James, 2013). A limited income and having to economise in many areas of life can take a toll on health and well-being. This dissertation examines the associations between experiences of financial hardship, perceived strain and psychological well-being for young adults at university. How these associations differ for student young adults with and without supportive resources is then examined. Finally, the associations between financial normative socialisation and young adults’ financial behaviours are explored between students and full-time workers. Two samples of Australian young adults were surveyed. The first two studies include 614 Western Australian university students (67% female, Mage = 20.83, SDage = 2.02) drawn from a single tertiary institution as part of the Australian Pathways to Life Success for University Students (AusPLUS) survey. The third study includes a sample of 301 Western Australians (68% female, Mage = 18.15, SDage = 1.04) surveyed as part of the Post-High School follow up to the Youth Activity Participation Study (YAPS). In both samples, respondents completed a web-based survey.

Momentum-space probability density of ${}^6$He in Halo Effective Field Theory

description: We compute the momentum-space probability density of ${}^6$He at leading order in Halo EFT. In this framework, the ${}^6$He nucleus is treated as a three-body problem with a ${}^4$He core ($c$) and two valence neutrons ($n$). This requires the $nn$ and $nc$ t-matrices as well as a $cnn$ force as input in the Faddeev equations. Since the $nc$ t-matrix corresponds to an energy-dependent potential, we consider the consequent modifications to the standard normalization and orthogonality conditions. We find that these are small for momenta within the domain of validity of Halo EFT. In this regime, the ${}^6$He probability density is regulator independent, provided the cutoff is significantly above the EFT breakdown scale.

description: The cosmic star formation history in Cold Dark Matter dominated cosmological scenarios is studied by means of hydrodynamical numerical simulations. In particular, we explore a low density model with a Lambda-term and two high density models with different power spectra, all of them being spatially flat. Our simulations employ a fully nonlinear N-body and Eulerian hydrodynamics algorithm with a model for star formation and supernovae feedback that depends on two phenomenological parameters determined in agreement with previous papers. We find a nearly constant star formation rate beyond z=1, and we discuss which facts may determine the decrease in the SFR from z=1 to the present epoch. The Lambda-term cosmology with realistic parameters for star formation and feedback best reproduces the observed star formation history.
