description: We analyze the link between active galactic nuclei (AGN) and mid-infrared flux using dust radiative transfer calculations of starbursts realized in hydrodynamical simulations. Focusing on the effects of galaxy dust, we evaluate diagnostics commonly used to disentangle AGN and star formation in ultraluminous infrared galaxies (ULIRGs). We examine these quantities as a function of time, viewing angle, dust model, AGN spectrum, and AGN strength in merger simulations representing two possible extremes of the ULIRG population: one is a typical gas-rich merger at z ~ 0, and the other is characteristic of extremely obscured starbursts at z ~ 2 to 4. This highly obscured burst begins star-formation-dominated with significant PAH emission, and ends with a ~10^9 yr period of red near-IR colors. At coalescence, when the AGN is most luminous, dust obscures the near-infrared AGN signature, reduces the relative emission from polycyclic aromatic hydrocarbons (PAHs), and enhances the 9.7 micron absorption by silicate grains. Although generally consistent with previous interpretations, our results imply none of these indicators can unambiguously estimate the AGN luminosity fraction in all cases. Motivated by the simulations, we show that a combination of the extinction feature at 9.7 micron, the PAH strength, and a near-infrared slope can simultaneously constrain the AGN fraction and dust grain distribution for a wide range of obscuration. We find that this indicator, accessible to the James Webb Space Telescope, may estimate the AGN power as tightly as the hard X-ray flux alone, thereby providing a valuable future cross-check and constraint for large samples of distant ULIRGs.

description: Precision management of the mango crop can be aided by quantitative measures of indices relevant to fruit maturation and measurement of the fruit load per tree. Such measures address fruit quantity and quality, respectively. Mango fruit DM at harvest is an index of ripened fruit eating quality of ripened fruit, and DM is also useful in assessment of the stage of maturation of the fruit. This thesis considered the robustness of NIR spectroscopy based DM models for use with fruit from different harvest events and of five cultivars (Calypso™, Honey Gold, Keitt, Kensington Pride and R2E2), from two distinct growing regions (Northern Territory and Queensland, over two seasons). Individual cultivar calibrations achieved cross validation statistics of Rcv2 = 0.85-0.93; RMSECV = 0.61-0.96% DM, while a combined cultivar (global) model had satisfactory statistics of Rcv2 = 0.84; RMSECV = 0.99% DM.

description: In this letter we propose a test to detect the linearity of the dark energy equation of state, and apply it to two different Type Ia Supernova (SN Ia) data sets, Union2.1 and SNLS3. We find that: a. current SN Ia data are well described by a dark energy equation of state linear in the cosmic scale factor a, at least up to a redshift z = 1, independent of the pivot points chosen for the linear relation; b. there is no significant evidence of any deviation from linearity. This apparent linearity may reflect the limit of dark energy information extractable from current SN Ia data.

description: In human crowds, interactions among individuals give rise to a variety of self-organized collective motions that help the group to effectively solve the problem of coordination. However, it is still not known exactly how humans adjust their behavior locally, nor what are the direct consequences on the emergent organization. One of the underlying mechanisms of adjusting individual motions is the stepping dynamics. In this paper, we present first quantitative analysis on the stepping behavior in a one-dimensional pedestrian flow studied under controlled laboratory conditions. We find that the step length is proportional to the velocity of the pedestrian, and is directly related to the space available in front of him, while the variations of the step duration are much smaller. This is in contrast with locomotion studies performed on isolated pedestrians and shows that the local density has a direct influence on the stepping characteristics. Furthermore, we study the phenomena of synchronization -walking in lockstep- and show its dependence on flow densities. We show that the synchronization of steps is particularly important at high densities, which has direct impact on the studies of optimizing pedestrians flow in congested situations. However, small synchronization and antisynchronization effects are found also at very low densities, for which no steric constraints exist between successive pedestrians, showing the natural tendency to synchronize according to perceived visual signals.

description: Some reports of supernova (SN) discoveries turn out not to be true core-collapse explosions. One such case was SN 2009ip, which was recognized to be a luminous blue variable (LBV) eruption. This source had a massive hot progenitor star identified in pre-explosion data, it had documented evidence of pre-outburst variability, and it was subsequently discovered to have a 2nd outburst in 2010. This same source rebrightened again in 2012, and early spectra showed the same narrow-line profiles as before, suggesting another LBV-like eruption. We present new photometry and spectroscopy of SN 2009ip, indicating that it has transitioned into a true SN. The most striking discovery in these data is that unlike previous reports, the spectrum exhibited Balmer lines with very broad P-Cygni profiles characteristic of normal Type II supernovae (SNe II), in addition to narrow emission lines seen in SNe IIn and LBVs. Emission components have FWHM 8000 km/s, while the P-Cygni absorption component has blue wings extending to -13,000 km/s. These velocities are typical of SNe II, but have never been associated with emission lines from a nonterminal LBV-like eruption. Initially, the peak absolute magnitude seemed fainter than that of normal SNe. However, after a brief period of fading, the source quickly brightened again to M_R=-17.5 mag over a couple days. The broad lines mostly disappeared, and the spectrum began to resemble the early optically thick phases of SNe IIn. Two weeks later the source leveled off near -18 mag, after which broad emission lines again developed in the spectrum as the source faded. We conclude that the 2012 outburst of SN 2009ip was the result of a true core-collapse SN IIn that occured when the progenitor star was in an LBV-like outburst phase, and where the SN was initially faint and then rapidly brightened due to interaction with circumstellar material (abridged).

description: Relativistic shocks that accompany supernovae (SNe) produce X-ray burst emissions as they break out in the dense circumstellar medium around the progenitors. This phenomenon is sometimes associated with peculiar low-luminosity gamma-ray bursts (LL GRBs). Here, we investigate the high energy neutrino and gamma-ray counterparts of such a class of SNe. Just beyond the shock breakout radius, particle acceleration in the collisionless shock starts to operate in the presence of breakout photons. We show that protons may be accelerated to sufficiently high energies and produce high energy neutrinos and gamma rays via the photomeson interaction. These neutrinos and gamma rays may be detectable from 10 Mpc away by IceCube/KM3Net as multi-TeV transients almost simultaneously with the X-ray burst emission, and even from 100 Mpc away with follow-up observations by CTA using a wide-field sky monitor like Swift as a trigger. A statistical technique using a stacking approach could also be possible for the detection, with the aid of the SN optical/infrared counterparts. Such multi-messenger observations offer the possibility to probe the transition of relativistic shocks from radiation-mediated to collisionless ones, and would also constrain the mechanisms of particle acceleration and emission in LL GRBs.

description: We present a global study of the simplest scalar phantom dark matter model. The best fit parameters of the model are determined by simultaneously imposing (i) relic density constraint from WMAP, (ii) 225 live days data from direct experiment XENON100, (iii) upper limit of gamma-ray flux from Fermi-LAT indirect detection based on dwarf spheroidal satellite galaxies, and (iv) the Higgs boson candidate with a mass about 125 GeV and its invisible branching ratio no larger than 40% if the decay of the Higgs boson into a pair of dark matter is kinematically allowed. The allowed parameter space is then used to predict annihilation cross sections for gamma-ray lines, event rates for three processes mono-b jet, single charged lepton and two charged leptons plus missing energies at the Large Hadron Collider, as well as to evaluate the muon anomalous magnetic dipole moment for the model.

description: Cancer is a challenging chronic disease. For families affected by hereditary cancers, understanding and adapting to the disease is complex. A Maori family in New Zealand have recently been found to have a genetically inherited form of stomach cancer – hereditary diffuse gastric cancer. They are armed with genetic knowledge about their predisposition to the disease and can take steps to avert the cancer but this knowledge does create risk and psychosocial ramifications. The aim of the study was to explore the experience of being predisposed to hereditary diffuse gastric cancer from members on one Maori family. The existing literature had an advanced scientific understanding of the cancer and led to useful treatment guidelines, but a subjective understanding of the experience of the cancer was limited. The study reported in this thesis used a narrative inquiry methodology to understand the subjective experience of being predisposed to the stomach cancer. Eight people were interviewed and the stories they shared revealed the complexities of how the illness was uniquely experienced, in context, and over time. Nuances were also uncovered about human interactions with health care providers.

This preservation is of strong contemporary interest in computer graphics and visualization. We establish a criterion to preserve knot type under approximation that relies upon pointwise convergence and convergence in total curvature.

description: We explore the connections between various coordinate systems associated with observers moving inwardly along radial geodesics in the Schwarzschild geometry. Painlevé-Gullstrand (PG) time is adapted to freely falling observers dropped from rest from infinity; Lake-Martel-Poisson (LMP) time coordinates are adapted to observers who start at infinity with non-zero initial inward velocity; Gautreau-Hoffmann (GH) time coordinates are adapted to observers dropped from rest from a finite distance from the black hole horizon. We construct from these an LMP family and a proper-time family of time coordinates, the intersection of which is PG time. We demonstrate that these coordinate families are distinct, but related, one-parameter generalizations of PG time, and show linkage to Lemaître coordinates as well.

description: Ultracompact minihalos would be formed if there are larger density perturbations ($0.0003 < δρ/ρ< 0.3$) in the earlier epoch. The density profile of them is steeper than the standard dark matter halos. If the dark matter can annihilate or decay into the standard particles, e.g., photons, these objects would be the potential astrophysical sources. In order to be consistent with the observations, such as $Fermi$, the abundance of ultracompact minihalos must be constrained. On the other hand, the formation of these objects has very tight relation with the primordial curvature perturbations on smaller scale, so the fraction of ultracompact minihalos is very important for modern cosmology. In previous works, the studies are focused on the dark matter annihilation for these objects. But if the dark matter is not annihilated, the dark matter decay is another important possible case. On the other hand, the abundance of ultracompact minihalos is related to many other parameters, such as the mass of dark matter, the decay channels and the density profile of dark matter halo. One of the important aspects of this work is that we investigate the $γ$-ray signals from nearby ultracompact minihalos due to dark matter decay and another important aspect is to study in detail how the different decay channels and density profiles affect the constraints on the abundance of ultracompact minihalos.

description: Neutrophil extracellular traps (NETs) are involved in bacterial killing as well as autoimmunity, because NETs contain proteases, bactericidal peptides, DNA and ribonucleoprotein. NETs are formed via a novel type of cell death called NETosis. NETosis is distinct from apoptosis, but it resembles necrosis in that both membranes are not intact so that they allow intracellular proteins to leak outside of the cells. Removal of NETs and neutrophils undergoing NETosis by phagocytes and its subsequent response are not completely clarified, as compared with the response after removal of either apoptotic or necrotic neutrophils by phagocytes. How neutrophil density in peripheral blood is kept within a certain range is important for health and disease. Although the studies on severe congenital neutropenia and benign ethnic neutropenia have provided unbiased views on it, the studies are rather limited to human neutropenia, and mice with a mutation of mouse counterpart gene often fail to exhibit neutropenia. Degranulation plays a critical role in bactericidal action. The recent studies revealed that it is also involved in immunomodulation, pain control and estrous cycle control. N1 and N2 are representative of neutrophil subpopulations. The dichotomy holds true in patients or mice with severe trauma or cancer, providing the basis of differential roles of neutrophils in diseases.

The coloring game on matroids

description: A coloring of the ground set of a matroid is proper if elements of the same color form an independent set. For a loopless matroid $M$, its chromatic number $χ(M)$ is the minimum number of colors in a proper coloring. In this note we study a game-theoretic variant of this parameter. Suppose that Alice and Bob alternately properly color the ground set of a matroid $M$ using a fixed set of colors. The game ends when the whole matroid has been colored, or if they arrive to a partial coloring that cannot be further properly extended. Alice wins in the first case, while Bob in the second. The game chromatic number of $M$, denoted by $χ_{g}(M)$, is the minimum size of the set of colors for which Alice has a winning strategy. Clearly, $χ_{g}(M)\geqχ(M)$. We prove an upper bound $χ_{g}(M)\leq 2χ(M)$ for every matroid $M$. This improves and extends a result of Bartnicki, Grytczuk and Kierstead, who showed that $χ_{g}(M)\leq 3χ(M)$ holds for graphic matroids. Our bound is almost tight, as we construct a family of matroids $M_k$ (for $k\geq 3$) satisfying $χ(M_k)=k$ and $χ_{g}(M_k)=2k-1$.

description: An ageing population challenges healthcare systems and resources. Efforts are underway in Australia and around the world to find alternatives to hospitalisation for older persons, particularly those transferred from residential aged care facilities (RACFs), where emergency transfers are frequent, costly, stressful for residents, and often considered unnecessary or preventable. RACF nursing staff play a pivotal role in managing residents with deteriorating health and hospital avoidance efforts; therefore, information on their intentions and perceptions regarding this area of their work is needed to underpin programs that aim to enhance nursing skills and confidence. The overarching aim of the study presented in this thesis is to understand and identify factors that influence RACF nursing staff management of residents with deteriorating health.

description: Disruption in cold chain during distribution and retail could have a significant impact on in‐package condensation of optimally designed packaged fresh produce. The aim of this work was to regulate in‐package condensation and evaluate the performance of different packaging design systems for strawberries under fluctuating temperatures (between 10°C and 20°C) for 5 days. The design included the use of condensation control strategies, namely, enhanced permeable films (NatureFlex and Xtend) and FruitPad of different fructose content (0%, 20%, 30%, 35%, and 40%). Package performance was evaluated in terms of headspace gas composition, mass loss, condensation, physico‐chemical changes, and visual and ortho‐nasal quality evaluation. Percentage mass loss of packaged strawberries ranged from 0.6% to 4% and was 33% for unpackaged. Results also showed that compared with the control sample, both strategies (enhanced permeable films and FruitPads) were effective in reducing condensation. In addition, transpirational water loss, results of the water absorbed by the FruitPads and transferred through the films were used to understand the packaging design needs under fluctuating temperature.

description: Arrays of suitably patterned and arranged magnetic elements may display artificial spin-ice structures with topological defects in the magnetization, such as Dirac monopoles and Dirac strings. It is known that these defects strongly influence the quasi-static and equilibrium behavior of the spin-ice lattice. Here we study the eigenmode dynamics of such defects in a square lattice consisting of stadium-like thin film elements using micromagnetic simulations. We find that the topological defects display distinct signatures in the mode spectrum, providing a means to qualitatively and quantitatively analyze monopoles and strings which can be measured experimentally.

A simple consequence is the change of the concept of target entity from a single protein to a whole molecular pathway and or cellular network. Deep-sea-derived drugs fit well to this new concept.

description: Animal rights campaigners use a variety of strategies to challenge the conventional view that it is the prerogative of humans to use animals as they see fit. However, no psychological examination of the effectiveness of these strategies has been undertaken. The present research examined the emotional response, within the Belief Disconfirmation paradigm of cognitive dissonance theory, to images exemplifying identified campaign strategies.

description: We decompose sphere partition functions and indices of three-dimensional N=2 gauge theories into a sum of products involving a universal set of "holomorphic blocks". The blocks count BPS states and are in one-to-one correspondence with the theory's massive vacua. We also propose a new, effective technique for calculating the holomorphic blocks, inspired by a reduction to supersymmetric quantum mechanics. The blocks turn out to possess a wealth of surprising properties, such as a Stokes phenomenon that integrates nicely with actions of three-dimensional mirror symmetry. The blocks also have interesting dual interpretations. For theories arising from the compactification of the six-dimensional (2,0) theory on a three-manifold M, the blocks belong to a basis of wavefunctions in analytically continued Chern-Simons theory on M. For theories engineered on branes in Calabi-Yau geometries, the blocks offer a non-perturbative perspective on open topological string partition functions.

Regional governance for resilient coastal agricultural systems: the case of the Burnett Mary Region, Australia
Creators: name: Gunasekara, Galwolu
Publisher: name: CQUniversity
Year: 2023
Subjects: classificationCode: 441002
subject: Environmental sociology

description: Threats to coastal agricultural systems from extreme weather events and impacts of climate change require governance systems that build capacity so as to foster system resilience in response to natural disasters. The Burnett Mary (BM) region of Queensland, a high-value agricultural system in coastal Australia, was selected for this study because of its high vulnerability to extreme weather events and projected climate change impacts, the weak adaptive capacity of the farming communities, and on-going governance challenges. Using Interactive Governance Theory (IGT) as a theoretical framework to explore collaborative governance, this research examined the natural resource governance system of the Burnett Mary region. The purpose of the study was to understand the governance challenges and opportunities, and the system requirements that might improve Natural Resource Management (NRM) and to build the adaptive capacity of regional and local stakeholders. The overall research question guiding this thesis was: How does regional governance of natural resources build resilient coastal agricultural systems in Burnett Mary Region? To explore this question in detail, three sub-research questions were asked: (1) How are natural resources governed in this coastal agricultural system?; (2) How has natural resource governance in Burnett Mary region changed as a result of episodic flooding?; (3) How can the regional natural resource governance system of Burnett Mary region adapt to and be more resilient to future extreme weather events?
An exploration of leadership of registered nurses in clinical settings
Creators: name: Chapman, Maureen

Year: 2023
Subjects: classificationCode: 420599
subject: Nursing not elsewhere classified

description: Nurses provide leadership at various levels throughout healthcare organisations as Directors of Nursing, Chief Nursing Officers, as well as clinical leaders at a unit level. Existing research into nursing leadership has mainly focussed on transformational and transactional forms of leadership, which has been at the expense of exploring more contemporary forms of leadership. Furthermore there is limited research into the experiences of leadership from registered nurses working in the clinical settings. This research explored the extent and appropriateness of four forms of leadership namely transactional, transformational, distributed and hybrid leadership as it applies in to clinical nursing.
Noise Kernel for Self-similar Tolman Bondi Metric: Fluctuations on Cauchy Horizon

description: We attempt to calculate the point separated Noise Kernel for self similar Tolman Bondi metric, using a method similar to that developed by Eftekharzadeh et. al for ultra-static spacetimes referring to the work by Page. In case of formation of a naked singularity, the Noise Kernel thus obtained is found to be regular except on the Cauchy horizon, where it diverges. The behavior of the noise in case of the formation of a covered singularity is found to be regular. This result seemingly renders back reaction non-negligible which questions the stability of the results obtained from the semiclassical treatment of the self similar Tolman Bondi metric.
Influential factors in the flow experiences of mobile game players

Publisher: name: CQUniversity

Subjects: classificationCode: 360502
subject: Computer gaming and animation

description: This thesis presents a grounded theory of the flow experiences of mobile game players. Flow is a deeply satisfying state of focused attention that can occur while engaging in a challenging activity such as playing mobile game. Flow experiences are characterised by some common elements, which include: a challenging activity that requires skills; the merging of action and awareness; clear goals; direct, immediate feedback; concentration on the task at hand; a sense of control; a loss of self-consciousness; an altered sense of time; and the autotelic experience. Flow is interesting to game designers because of its connection to important aspects of the user experience such as enjoyment and engagement. Understanding influential factors in the flow experiences of mobile game players could inform practice in the field of interaction design and contribute to the development of more engaging mobile games.
Integrable perturbations of conformal field theories and Yetter-Drinfeld modules

description: In this paper we relate a problem in representation theory - the study of Yetter-Drinfeld modules over certain braided Hopf algebras - to a problem in two-dimensional quantum field theory, namely the identification of integrable perturbations of a conformal field theory. A prescription that parallels Lusztig's construction allows one to read off the quantum group governing the integrable symmetry. As an example, we illustrate how the quantum group for the loop algebra of sl(2) appears in the integrable structure of the perturbed uncompactified and compactified free boson.

description: We present a rotationally invariant Hirsch-Fye quantum Monte Carlo algorithm in which the spin rotational invariance of Hund's exchange is approximated by averaging over all possible directions of the spin quantization axis. We employ this technique to perform benchmark calculations for the two- and three-band Hubbard models on the infinite-dimensional Bethe lattice. Our results agree quantitatively well with those obtained using the continuous-time quantum Monte Carlo method with rotationally invariant Coulomb interaction. The proposed approach is employed to compute the electronic and magnetic properties of paramagnetic $α$ iron and nickel. The obtained Curie temperatures agree well with experiment. Our results indicate that the magnetic transition temperature is significantly overestimated by using the density-density type of Coulomb interaction.

description: We present an optical group catalog between 0.1 < z < 1 based on 16,500 high-quality spectroscopic redshifts in the completed zCOSMOS-bright survey. The catalog published herein contains 1498 groups in total and 192 groups with more than five observed members. The catalog includes both group properties and the identification of the member galaxies. Based on mock catalogs, the completeness and purity of groups with three and more members should be both about 83% with respect to all groups that should have been detectable within the survey, and more than 75% of the groups should exhibit a one-to-one correspondence to the "real" groups. Particularly at high redshift, there are apparently more galaxies in groups in the COSMOS field than expected from mock catalogs. We detect clear evidence for the growth of cosmic structure over the last seven billion years in the sense that the fraction of galaxies that are found in groups (in volume-limited samples) increases significantly with cosmic time. In the second part of the paper, we develop a method for associating galaxies that only have photo-z to our spectroscopically identified groups. We show that this leads to improved definition of group centers, improved identification of the most massive galaxies in the groups, and improved identification of central and satellite galaxies, where we define the former to be galaxies at the minimum of the gravitational potential wells. Subsamples of centrals and satellites in the groups can be defined with purities up to 80%, while a straight binary classification of all group and non-group galaxies into centrals and satellites achieves purities of 85% and 75%, respectively, for the spectroscopic sample.

“Rock around the Real” Fictional bands on film: The evolution of an invisible genre
Creators: name: Butler, Stephen

subject: Screen and media culture

description: ‘To begin with, everything’– Russell Hammond (Almost famous) Rock music is a global phenomenon that originated in the 1950s and continues to the present day. The rock musician has become a ubiquitous figure in a wide range of mass media forms: novels, biographies, magazines, games, TV shows and films. Since rock music and its ‘project of authenticity’ (Keightley 2003) began ‘becoming residual’ (Grossberg 2002), a phenomenon sometimes characterized as the “death of rock” (Dettmar 2006), fictional band films have proliferated. This thesis documents the evolution of the fictional band film in terms of genre theory, the social history of rock, and the discourses of authenticity circulating in the media. The thesis employs poststructuralist film theory and semiotic analysis to elaborate on the significance of what might be regarded as an ‘invisible genre’ (Brown 2013). The study focuses on five feature films, each of which tells the story of a fictional band in a particular phase of what Bennett (1991, p. 147) calls the ‘paradigmatic rock’n’roll career’: cult phase, crossing over, transcendence, decline, and comeback. In contrast to the prevalent critical view that the rock fiction film is inferior to non-fictional genres such as the documentary, concert film and biopic, analysis suggests that the fictional band film is a specific performance of rock, and perhaps rock’s paradigmatic cinematic expression.

description: A (holomorphic) quantization of a complex contact manifold is a filtered algebroid stack which is locally equivalent to the ring E of microdifferential operators and which has trivial graded. The existence of a canonical quantization has been proved by Kashiwara. In this paper we consider the classification problem, showing that the above quantizations are classified by the first cohomology group with values in a certain sheaf of homogeneous forms. Secondly, we consider the problem of existence and classification for quantizations given by algebras.
