description: We exhaust all exact self-consistent solutions of complex-valued fermionic condensates in the 1+1 dimensional Bogoliubov-de Gennes and chiral Gross-Neveu systems under uniform boundary conditions. We obtain $n$ complex (twisted) kinks, or grey solitons, with $2n$ parameters corresponding to their positions and phase shifts. Each soliton can be placed at an arbitrary position while the self-consistency requires its phase shift to be quantized by $π/N$ for $N$ flavors.

description: Point-like Liouville integrable dynamical defects are introduced in the context of the Landau-Lifshitz and Principal Chiral (Faddeev-Reshetikhin) models. Based primarily on the underlying quadratic algebra we identify the first local integrals of motion, the associated Lax pairs as well as the relevant sewing conditions around the defect point. The involution of the integrals of motion is shown taking into account the sewing conditions.

The role and function of remote area nurses at Birdsville 1923-1953
Creators: name: Klotz, Jeanette

Year: 2023
Subjects: classificationCode: 429999
subject: Other health sciences not elsewhere classified

description: This dissertation examines the way in which the role and function of remote area nurses (RANs) employed by the Australian Inland Mission (AIM), was established and developed during the years 1923 to 1953 at Birdsville in far south-west Queensland. In a geographically remote and technologically isolated environment, registered trained nurses in the absence of any other on-site medical or allied health personnel, provided the only formal health service to the people of Birdsville and the surrounding district. A unique feature of the AIM'S nursing service is that it was designed to meet the holistic health needs of isolated white people and apart from strictly clinical services, did not include the local indigenous population. In effect, the nurses' role and function developed within a framework of institutional racism. Free of the rigid hierarchical constraints and structures experienced during this time period by their metropolitan colleagues, the RANs at Birdsville developed their role and function within the broader context of this remote community's culture. In such a small community as Birdsville, community dynamics and politics based on the concepts of class, religion and ethnicity were considerably heightened. Within this environment, the ability of the nurses to effectively carry out their role and function for all of the community, was at times severely challenged and restricted. Essentially, the nurses shared with the community harsh climatic and living conditions which were exacerbated at times by the AIM'S inability to raise sufficient funds to adequately support their nursing staff. The nurses' professional isolation although apparent throughout the period under study, was most acute in the first few years prior to the installation of a pedal radio transceiver at Birdsville. During these early years their extended scope of clinical practice was established. However, it is demonstrated within the dissertation that even with improved communication and aviation technology, a high degree of autonomy in their clinical decision-making was maintained and incorporated into a culture of remote area nursing.

description: Community detection is the process of assigning nodes and links in significant communities (e.g. clusters, function modules) and its development has led to a better understanding of complex networks. When applied to sizable networks, we argue that most detection algorithms correctly identify prominent communities, but fail to do so across multiple scales. As a result, a significant fraction of the network is left uncharted. We show that this problem stems from larger or denser communities overshadowing smaller or sparser ones, and that this effect accounts for most of the undetected communities and unassigned links. We propose a generic cascading approach to community detection that circumvents the problem. Using real and artificial network datasets with three widely used community detection algorithms, we show how a simple cascading procedure allows for the detection of the missing communities. This work highlights a new detection limit of community structure, and we hope that our approach can inspire better community detection algorithms.

description: A kinetic theory can be modified to incorporate triangle anomalies and the chiral magnetic effect by taking into account the Berry curvature flux through the Fermi surface. We show how such a kinetic theory can be derived from underlying quantum field theories. Using the new kinetic theory, we also compute the parity-odd correlation function that is found to be identical to the result in the perturbation theory in the next-to-leading order hard dense loop approximation.

description: We show that the two dimensional Ising model is complete, in the sense that the partition function of any lattice model on any graph is equal to the partition function of the 2D Ising model with complex coupling. The latter model has all its spin-spin coupling equal to iπ/4 and all the parameters of the original model are contained in the local magnetic fields of the Ising model. This result has already been derived by using techniques from quantum information theory and by exploiting the universality of cluster states. Here we do not use the quantum formalism and hence make the completeness result accessible to a wide audience. Furthermore our method has the advantage of being algorithmic in nature so that by following a set of simple graphical transformations, one is able to transform any discrete lattice model to an Ising model defined on a (polynomially) larger 2D lattice.

description: Nachhaltige Kleidung geht verglichen mit dessen Fast-Fashion Alternative oft mit einem erhöhten Preis einher. In dieser Bachelorarbeit wird für das nachhaltige Modelabel thoughts of september untersucht, welche Bedürfnisse Konsumierende haben, damit sie die erhöhten Preise von nachhaltigen Kleidungsstücken als gerechtfertigt und fair sehen und bereit sind diesen zu bezahlen. Demnach behandelt diese Arbeit folgende Fragestellung: „Wie können Konsumierende, trotz erhöhter Preise von nachhaltiger Kleidung, zu nachhaltigem Kleiderkonsum angeregt werden?“. Dabei wurde untersucht, ob das Wissen über den Kleiderkonsum und dessen Konsequenzen, über die Verfügbarkeit am Markt und über Preiszusammensetzung, sowie die Sensibilisierung für diese Themen einen positiven Effekt auf den Konsum nachhaltiger Kleidung haben. Zudem wurde untersucht, ob der Preis den grössten Hinderungsgrund von nachhaltigem Kleiderkonsum darstellt und somit den grössten negativen Effekt darauf hat. Dafür wurden qualitative Leitfaden-Interviews mit potenziellen Kundinnen von thoughts of september durchgeführt. Dabei wurden Themen wie Nachhaltigkeit in der Kleiderbranche, Hinderungs- und Motivationsgründe, Wissen, Preiswahrnehmung und Sensibilisierung erhoben. Aus den gewonnenen Erkenntnissen folgte die Ableitung praktischer Lösungsansätze für das Unternehmen. Der vorgeschlagene Hauptlösungsansatz ist die Sensibilisierung von Konsumierenden für Nachhaltigkeit und Preisgestaltung in der Kleiderbranche.

description: High-order nonlinear light-matter interactions in gases enable generation of x-ray and attosecond light pulses, metrology, and spectroscopy. Optical nonlinearities in solid-state materials are particularly interesting for combining optical and electronic functions for high-bandwidth information processing. Third-order nonlinear optical processes in silicon have been used to process optical signals with greater than 1 GHz bandwidths. Fundamental physical processes for a Si-based optical modulator in the THz bandwidth range, however, have not yet been explored. Here we demonstrate ultrafast phononic modulation of the optical index of Si by irradiation with intense few-cycle femtosecond pulses. The anisotropic reflectivity modulation by the resonant Raman susceptibility at the fundamental frequency of the longitudinal optical (LO) phonon of Si (15.6 THz) generates a frequency comb up to 7th-order. All optical >100 THz frequency comb generation is realized by harnessing the coherent atomic motion of the Si crystalline lattice at its highest mechanical frequency.

description: We theoretically study the deterministic generation of photon Fock states on-demand using a protocol based on a Jaynes Cummings quantum random walk which includes damping. We then show how each of the steps of this protocol can be implemented in a low temperature solid-state quantum system with a Nitrogen-Vacancy centre in a nano-diamond coupled to a nearby high-Q optical cavity. By controlling the coupling duration between the NV and the cavity via the application of a time dependent Stark shift, and by increasing the decay rate of the NV via stimulated emission depletion (STED) a Fock state with high photon number can be generated on-demand. Our setup can be integrated on a chip and can be accurately controlled.

description: The model of quantum associative memories (QAM) we propose here consists in simplifying and generalizing that of Rigui Zhou \etal \cite{zhou2012} who uses the quantum matrix with binary decision diagram and nonlinear search algorithm in his model. It is worth noting that David Rosenbaum put forth the quantum matrix with binary decision diagram \cite{Rosenbaum2010} and Abrams and Llyod did the nonlinear algorithm. \cite{Abrams1998} Our model gives the possibility to retrieve one of the sought states in multi-values retrieving scheme when a measure on the first register is done. It is better than Grover's algorithm and its modified form which need $\mathcal{O}(\sqrt{\frac{2^n} {m}})$ steps when they are used as the retrieval algorithm. $n$ is the number of qubit of the first register and $m$ the number of values $x$ for which $f(x)=1$. As the nonlinearity makes the system highly susceptible to noise, an analysis of the influence of the single qubit noise channels on the Nonlinear Search Algorithm of our model of QAM, shows a fidelity of about $0.7$ whatever the number of qubits present in the first register.

Benefits of aeration of subsurface drip irrigation water: Field evidence on CQ highlands vertosols

Subjects: classificationCode: 300499
subject: Crop and pasture production not elsewhere classified

description: Irrigation of heavy soils can result in temporary anoxic conditions in the rhizosphere. The aeration of the subsurface drip irrigation water was calculated to deliver an amount of oxygen that is significant to root respiration (equivalent to some hours of respiration need). Broadacre cotton (Gossypium hirsutum L.) irrigated with aerated water developed significantly more extensive and heavier (17.3%) root systems, canopies that enabled greater light interception (2.6% ), and produced significantly higher lint yields ( 16%) due to more bolls per plant (15%) in the 05/06 season. The increased yields of aerated plants were associated with improved gross production water use index (GPWUI), irrigation water use index (IWUI) and crop water use index (CWUI) by 16.9, 16.8 and 15.5% respectively. These improvements in yields and water use efficiencies in response to aeration were ascribed to enhanced root development and performance. Although trends were similar across two seasons, the differences were not significantly different in the first (04/05) season, a result attributed to inadequate replication in the trials of that year. A chickpea ( Cicer arietinum L.) crop grown in rotation to cotton produced significantly higher yields (26.9%; 359 vs. 283 g m-2), IWUI (27%, 2400 vs. 1890 g m-3) and GPWUI (26.8%; 1750 vs. 1380 g m-3) under aerated SDI, compared to nonaerated SDI. The aeration effect was more pronounced when drippers were placed at depth (25 and 35 em, compared to 5 and 15 em) (chickpea pot experiment). Aerated chickpea irrigated at the deepest emitter depth produced significantly higher yields (by 1 0.9%) and GPWUI (21 %) than their non-aerated counterparts. A field sorghum (Sorghum bicolor L.) crop grown following the second chickpea crop did not respond to the aeration treatment in terms of yield or water use efficiency (WUE), a result attributable to either the effect of a relatively wet season where the contribution of irrigation to total water use was less than 50%, or to a relative insensitivity of sorghum to soil anoxia. Aeration of SDI water improved cotton plant growth (larger root systems, heavier above-ground biomass and higher yield) for irrigation water with an electrical conductivity of0.78 dSm-1, but not at higher levels. The ratios of cotton leaf K+:Na+, Ca2+:Na+ and Mg2+:Na+ were increased (by 45.7%, 31.7% and 34.9%, respectively) by the aeration treatment, compared to the control, suggesting a higher level of salt exclusion by the root in the aerated treatments. This result is interpreted as due to maintenance of membrane integrity under aerobic conditions. Aeration of SDI has the potential to make a major contribution to sustainable water use for irrigated agriculture on heavy soils. The benefits of aeration of SDI in terms of both crop yield and water use efficiency improve the economic feasibility of this irrigation method.
Regulation of the spectral peak in gamma-ray bursts
Creators: name: Beloborodov, Andrei M.
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Observations indicate that the peak of gamma-ray burst spectrum forms in the opaque region of an ultra-relativistic jet. Recent radiative transfer calculations support this picture and show that the spectral peak is inherited from initially thermal radiation, which is changed by heating into a broad photon distribution with a high-energy tail. We discuss the processes that regulate the observed position of the spectral peak E_pk. The opaque jet has three radial zones: (1) Planck zone r>1 where radiation has a Bose-Einstein spectrum, and (3) Comptonization zone r>R_W where the radiation spectrum develops the high-energy tail. Besides the initial jet temperature, an important factor regulating E_pk is internal dissipation (of bulk motions and magnetic energy) at large distances from the central engine. Dissipation in the Planck zone reduces E_pk, and dissipation in the Wien zone increases E_pk. In jets with sub-dominant magnetic fields, the predicted E_pk varies around 1 MeV up to a maximum value of about 10 MeV. If the jet carries an energetically important magnetic field, E_pk can be additionally increased by dissipation of magnetic energy. This increase is hinted by observations, which show E_pk up to about 20 MeV. We also consider magnetically dominated jets; then a simple model of magnetic dissipation gives E_pk~30 Gamma_W keV where Gamma_W is the jet Lorentz factor at the Wien radius R_W.

description: The recently developed framework of anisotropic hydrodynamics is generalized to describe the dynamics of coupled quark and gluon fluids. The quark and gluon components of the fluids are characterized by different dynamical anisotropy parameters. The dynamical equations describing such mixtures are derived from kinetic theory with the collisional kernel treated in the relaxation- time approximation allowing for different relaxation times for quarks and gluons. Baryon number conservation is enforced in the quark and anti-quark components of the fluid, but overall parton number non-conservation is allowed in the system. The resulting equations are solved numerically in the (0+1)-dimensional boost-invariant case at zero and finite baryon density.

description: "Robots are playing increasingly important roles in our lives. They are widely used in industries and in non-invasive surgeries. Robots also place satellites into orbits and do maintenance work outside the Space Station. At sea, remotely controlled mobile underwater vehicles are used in search and rescue missions. Robo-planes photograph enemy positions and transmit intelligence. Robots will also be clearing land mines and decontaminate polluted sites. Hence, robots are important in today's world. The aim of this thesis is to investigate the control of flexible robots. The objectives are to accurately position the payload at the tip of the arm and suppress vibrations of the links. As simulations were used in this study, different models for robots are first looked at. Next, the various control laws that are in use are studied. To overcome the shortcomings of these control laws, Terminal Sliding Mode Control and Sliding Mode Control used in combination with Linear Control are applied to control these flexible robots: the Mass Beam System, the Single Link Flexible Robot Manipulator and the Two Link Flexible Robot Manipulator. Results obtained show that finite time control of flexible robots can be achieved using the above mentioned control laws which have the added advantage that chatterings often present in conventional sliding mode control are absent when these forms of control are used. The thesis concludes with discussions on the contributions made and suggestions for further research."--Abstract

description: "This thesis ... examines colour as the hues we perceive in everyday activities and their social significance when used deliberately in representation ... investigations have led into psychological, anthropological, philosophical and cultural realms to uncover colour 'knowledge' and from there to semiology, representation and feminism in search of the tools with which to expose colour to a sociological analysis. What follows in this thesis is that journey, colour use examined in respect of its marking of gender attributes in a major social reproducer of these concepts, popular narrative film"--Abstract.

Mixed-symmetry tensor conserved currents and AdS/CFT correspondence
Creators: name: Alkalaev, K. B.
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We present the full list of conserved currents built of two massless spinor fields in Minkowski space and their derivatives multiplied by Clifford algebra elements. The currents have particular mixed-symmetry type described by Young diagrams with one row and one column of arbitrary lengths and heights. Along with Yukawa-like totally antisymmetric currents the complete set of constructed currents exactly matches the spectrum of AdS mixed-symmetry fields arising in the generalized Flato-Fronsdal theorem for two spinor singletons. As a by-product, we formulate and study general properties of primary fields and conserved currents of mixed-symmetry type.

Virtual Color-Kinematics Duality: 6-pt 1-Loop MHV Amplitudes
Creators: name: Yuan, Ellis Ye
Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study 1-loop MHV amplitudes in N=4 super Yang-Mills theory and in N=8 supergravity. For Yang-Mills we find that the simple form for the full amplitude presented by Del Duca, Dixon and Maltoni naturally leads to one that has physical residues on all compact contours. After expanding the simple form in terms of standard scalar integrals, we introduce redundancies under certain symmetry considerations to impose the color-kinematics duality of Bern, Carrasco and Johansson (BCJ). For five particles we directly find the results of Carrasco and Johansson as well as a new compact form for the supergravity amplitude. For six particles we find that all kinematic dual Jacobi identities are encapsulated in a single functional equation relating the expansion coefficients. By the BCJ double-copy construction we obtain a formula for the corresponding N=8 supergravity amplitude. Quite surprisingly, all physical information becomes independent of the expansion coefficients modulo the functional equation. In other words, there is no need to solve the functional equation at all. This is quite welcome as the functional equation we find, using our restricted set of redundancies, actually has no solutions. For this reason we call these results virtual color-kinematics duality. We end with speculations about the meaning of an interesting global vs. local feature of the functional equation and the situation at higher points.

Certifying 3-Edge-Connectivity
Creators: name: Mehlhorn, Kurt

name: Schmidt, Jens M.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Data Structures and Algorithms (cs.DS)

description: We present a certifying algorithm that tests graphs for 3-edge-connectivity; the algorithm works in linear time. If the input graph is not 3-edge-connected, the algorithm returns a 2-edge-cut. If it is 3-edge-connected, it returns a construction sequence that constructs the input graph from the graph with two vertices and three parallel edges using only operations that (obviously) preserve 3-edge-connectivity. Additionally, we show how compute and certify the 3-edge-connected components and a cactus representation of the 2-cuts in linear time. For 3-vertex-connectivity, we show how to compute the 3-vertex-connected components of a 2-connected graph.

Probing the cool ISM in galaxies via 21cm HI absorption

description: Recent targeted studies of associated HI absorption in radio galaxies are starting to map out the location, and potential cosmological evolution, of the cold gas in the host galaxies of Active Galactic Nuclei (AGN). The observed 21 cm absorption profiles often show two distinct spectral-line components: narrow, deep lines arising from cold gas in the extended disc of the galaxy, and broad, shallow lines from cold gas close to the AGN (e.g. Morganti et al. 2011). Here, we present results from a targeted search for associated HI absorption in the youngest and most recently-triggered radio AGN in the local universe (Allison et al. 2012b). So far, by using the recently commissioned Australia Telescope Compact Array Broadband Backend (CABB; Wilson et al. 2011), we have detected two new absorbers and one previously-known system. While two of these show both a broad, shallow component and a narrow, deep component (see Fig. 1), one of the new detections has only a single broad, shallow component. Interestingly, the host galaxies of the first two detections are classified as gas-rich spirals, while the latter is an early-type galaxy. These detections were obtained using a spectral-line finding method, based on Bayesian inference, developed for future large-scale absorption surveys (Allison et al. 2012a).

Quantitative sum rule analysis of low-temperature spectral functions

description: We analyze QCD and Weinberg-type sum rules in a low-temperature pion gas using vector and axial-vector spectral functions following from the model-independent chiral-mixing scheme. Toward this end we employ recently constructed vacuum spectral functions with ground and first-excited states in both channels and a universal perturbative continuum; they quantitatively describe hadronic tau-decay data and satisfy vacuum sum rules. These features facilitate the implementation of chiral mixing without further assumptions, and lead to in-medium spectral functions which exhibit a mutual tendency of compensating resonance and dip structures, suggestive for an approach toward structureless distributions. In the sum rule analysis, we account for pion mass corrections, which turn out to be significant. While the Weinberg sum rules remain satisfied even at high temperatures, the numerical evaluation of the QCD sum rules for vector and axial-vector channels reveals significant deviations setting in for temperatures beyond ~140 MeV, suggestive of additional physics beyond low-energy chiral pion dynamics.

Education in the "forty-year present": Perceptions of computer scientists on educational futures in a context of rapid technological change
Creators: name: Greening, Anthony
Publisher: name: CQUniversity
Year: 2023
Subjects: classificationCode: 399999
subject: Other education not elsewhere classified

description: This thesis argues that technological pervasiveness and rapid change effects shape the current context of education. It proposes that these effects are potentially transformative and may result in radical departures from traditional approaches to education in the near future. Perceptions of that future form the focus of the research. The concept of a "forty-year present" is used to represent a small window of time surrounding the present in which it is reasonable to conduct such discussion. A futurist approach to research is presented, and an iterative, Internet-based survey technique is used to gather some narrative data about educational futures from a small body of respondents with an interest in computer science education. The research approach itself is evaluated as part of the work and some recommendations for future Internet-based techniques are raised as a result. The data is used to generate an account of 37 futures issues raised by the respondent community, and to derive a list of 19 broad priorities for the future.
Molecular investigation of cellular immunity in marsupials

description: "The T cell signalling cascade is an important biochemical event in the adaptive immune system. In this study, various molecules involved in the T cell biology of marsupials were characterized. Investigation of possible differences in the molecular sequence of these genes was undertaken to explain why marsupials appear to respond differently to other mammals in their reaction to challenge by pathogens. Prior to this study it has been generally accepted that the adaptive immune system in marsupials may not function in the same manner as in other mammals"--Abstract.
