description: In recent years, deep learning has proven to be a viable methodology for surrogate modeling and uncertainty quantification for a vast number of physical systems. However, in their traditional form, such models can require a large amount of training data. This is of particular importance for various engineering and scientific applications where data may be extremely expensive to obtain. To overcome this shortcoming, physics-constrained deep learning provides a promising methodology as it only utilizes the governing equations. In this work, we propose a novel auto-regressive dense encoder-decoder convolutional neural network to solve and model non-linear dynamical systems without training data at a computational cost that is potentially magnitudes lower than standard numerical solvers. This model includes a Bayesian framework that allows for uncertainty quantification of the predicted quantities of interest at each time-step. We rigorously test this model on several non-linear transient partial differential equation systems including the turbulence of the Kuramoto-Sivashinsky equation, multi-shock formation and interaction with 1D Burgers' equation and 2D wave dynamics with coupled Burgers' equations. For each system, the predictive results and uncertainty are presented and discussed together with comparisons to the results obtained from traditional numerical analysis methods.

description: DeTurck and Yang have shown that in the neighbourhood of every point of a $3$-dimensional Riemannian manifold, there exists a system of orthogonal coordinates (that is, whith respect to which the metric has diagonal form). We show that this property does not generalize to higher dimensions. In particular, the complex projective spaces $\mathbb{CP}^m$ and the quaternionic projective spaces $\mathbb{HP}^q$, endowed with their canonical metrics, do not have local systems of orthogonal coordinates for $m,q\ge 2$.

description: Efficient manipulation of magnetization at ultrashort time scales is of particular interest for future technology. Here, we numerically investigate the influence of the so-called field-derivative torque, which was derived earlier based on relativistic Dirac theory [Mondal et al., Phys. Rev. B 94, 144419 (2016)], on the spin dynamics triggered by ultrashort laser pulses. We find that only considering the THz Zeeman field can underestimate the spin excitation in antiferromagnetic oxide systems as, e.g., NiO and CoO. However, accounting for both, the THz Zeeman torque and the field-derivative torque, the amplitude of the spin excitation increases significantly. Studying the damping dependence of field-derivative torque we observe larger effects for materials having larger damping constants.

title: Characterisation of Campylobacter jejuni glycoprotease and its Role in Bacteria - Host Interactions
Creators: name: Klipic, Zoran
Publisher: name: Griffith University
Year: 2011
Subjects: subject: Glycoprotease
subject: C. jejune Cj1344c
subject: Campylobacter species

description: The bacterial enzyme glycoprotease (gcp) was first discovered in the culture supernatant of Mannheimia (Pasteurella) haemolytica A1 associated with bovine pneumonic pasteurellosis. The enzyme is highly specific for O-sialoglycoproteins, but the function of the enzyme in bacterial homeostasis was not fully elucidated. The in silico analysis of C. jejuni genome strain NCTC11168 has revealed Cj1344c, a protein with predicted amino acid sequence showing 55% similarity to the M. haemolytica O-sialoglycoprotease. The C. jejuni Cj1344c homologue was present in all to-date sequenced strains of C. jejuni with higher than 97% amino acid identity and an orthologue of this enzyme was present in other Campylobacter species, with greater than 70% amino acid similarity. The glycoprotease was also present in the genomes of Campylobacter related species, such as Helicobacter and Wollinella with 65-70% similarity to C. jejuni Cj1344c. Comparative analysis also identified presence of orthologues in bacterial species such as Bacillus anthracis, Staphylococcus aureus and Haemophilus influenzae, with more than 49% amino acid similarity to the predicted Cj1344c amino acid sequence. In this study, the utilisation of gene mutagenesis approach demonstrated that a putative glycoprotease (Cj1344c) is required for C. jejuni survival and growth, as the inactivation of the gene by insertion of an antibiotic resistance gene cassette resulted in bacterial death. The gene products essential for bacterial growth in vitro and survival during infection constitute an initial set of protein targets for the development of antibacterial vaccines. The results of this study indicate that Cj1344c is a potential novel target for the development of antimicrobials against C. jejuni or a target for the development of a vaccine.

description: Cardiovascular diseases are a leading cause of death throughout the developed world. With the demand for donor hearts far exceeding the supply, a bridge-to-transplant or permanent solution is required. This can be achieved with rotary ventricular assist devices (VADs). Rotary VADs show a weaker response to preload than the native heart. This may lead to ventricular suction or pulmonary congestion, which can be deleterious to the patient’s recovery. A physiological control system which optimizes responsiveness of VADs may reduce adverse events. Active physiological control systems rely either on pressure and flow measurements or on estimated data. However these controllers may be limited by the low reliability of long term blood pressure and flow sensors or potential of inaccurate estimators due to changes in the VAD circuit (e.g. thrombus formation resulting in false estimation). A passive physiological control system might be able to overcome the limitation of active physiological control systems. This research project had three key aims: • Investigation of the steady state and time response of the healthy heart and circulatory system to changes in patient state (e.g. active postural changes and exercise). • In-vitro development and in-vivo validation of novel compliant inflow cannulae for rotary LVADs and RVADs to improve preload sensitivity of RBPs and provide a passive physiological control system for ventricular suction prevention. • Rigorous in-vitro evaluation of the compliant inflow cannulae together with various active physiological control systems previously presented in the literature under identical conditions.

description: The standard wisdom on the origin of massless bosons in the spectrum of a Quantum Field Theory $(QFT)$ describing the interaction of gauge fields coupled to matter fields is based on two well known features: gauge symmetry, and spontaneous symmetry breaking of continuous global symmetries. However we will show in this article how the topological properties, that originate the $U(1)_A$ axial anomaly in a $QFT$ which describes the interaction of fermion matter fields and gauge bosons, are the basis of an alternative mechanism to generate massless bosons in the chiral limit, if the non-abelian $SU(N_f)_A$ chiral symmetry is fulfilled in the vacuum. We will also test our predictions with the results of a well known two-dimensional model, the two-flavour Schwinger model, which was analyzed by Coleman long ago, and will give a reliable answer to some of the questions he asked himself on the spectrum of the model in the strong-coupling (chiral) limit. We will also analyze what are the expectations for the $U(N)$ gauge-fermion model in two dimensions, and will discuss on the impact of our results in the chirally symmetric high temperature phase of $QCD$, which was present in the early universe, and is expected to be created in heavy-ion collision experiments.

description: The tuning curve of the cochlea measures how large an input is required to elicit a given output level as a function of the frequency. It is a fundamental object of auditory theory, for it summarizes how to infer what a sound was on the basis of the cochlear output. A simple model is presented showing that only two elements are sufficient for establishing the cochlear tuning curve: a broadly tuned traveling wave, moving unidirectionally from high to low frequencies, and a set of mechanosensors poised at the threshold of an oscillatory (Hopf) instability. These two components suffice to generate the various frequency-response regimes which are needed for a cochlear tuning curve with a high slope.

description: The notion of symmetry is shown to be at the heart of all error correction/avoidance strategies for preserving quantum coherence of an open quantum system S e.g., a quantum computer. The existence of a non-trivial group of symmetries of the dynamical algebra of S provides state-space sectors immune to decoherence. Such noiseless sectors, that can be viewed as a noncommutative version of the pointer basis, are shown to support universal quantum computation and to be robust against perturbations. When the required symmetry is not present one can generate it artificially resorting to active symmetrization procedures.

description: The price of water to the urban consumer is one of the most politicised issues confronting state and federal legislators in Australia today. Water is an essential requirement of life and, arguably, there will always be a public sentiment that the price of water should not constitute an economic burden, least of all for those more economically disadvantaged members of society. As a result, and regardless of the "proper" underlying economic principles such as "user pays” and “full cost recovery”, there has always been a political willingness in Queensland, at both the state and local level, to continue with cross subsidies that distort the price of water. This has led to a political blame game amongst the major political parties that leaves the average consumer even more confused about the cost of water. Though the politics of water in Queensland may have seen the flight of rationality from public debate, the water industry itself has progressed substantially in recent years in securing a reliable future supply in South East Queensland (SEQ). On the supply side, important initiatives such as a desalination plant, dual reticulation schemes and provision for potable reuse have assured supply in SEQ for many years. The downside, however, is significant state debt and given the current public sensitivity to water pricing, passing this cost burden directly to the consumer is simply not on the agenda.

description: Object detection is one of the most important and challenging branches of computer vision, which has been widely applied in peoples life, such as monitoring security, autonomous driving and so on, with the purpose of locating instances of semantic objects of a certain class. With the rapid development of deep learning networks for detection tasks, the performance of object detectors has been greatly improved. In order to understand the main development status of object detection pipeline, thoroughly and deeply, in this survey, we first analyze the methods of existing typical detection models and describe the benchmark datasets. Afterwards and primarily, we provide a comprehensive overview of a variety of object detection methods in a systematic manner, covering the one-stage and two-stage detectors. Moreover, we list the traditional and new applications. Some representative branches of object detection are analyzed as well. Finally, we discuss the architecture of exploiting these object detection methods to build an effective and efficient system and point out a set of development trends to better follow the state-of-the-art algorithms and further research.

description: We investigate the scattering of strahl electrons by microinstabilities as a mechanism for creating the electron halo in the solar wind. We develop a mathematical framework for the description of electron-driven microinstabilities and discuss the associated physical mechanisms. We find that an instability of the oblique fast-magnetosonic/whistler (FM/W) mode is the best candidate for a microinstability that scatters strahl electrons into the halo. We derive approximate analytic expressions for the FM/W instability threshold in two different $β_{\mathrm c}$ regimes, where $β_{\mathrm c}$ is the ratio of the core electrons' thermal pressure to the magnetic pressure, and confirm the accuracy of these thresholds through comparison with numerical solutions to the hot-plasma dispersion relation. We find that the strahl-driven oblique FM/W instability creates copious FM/W waves under low-$β_{\mathrm c}$ conditions when $U_{0\mathrm s}\gtrsim 3w_{\mathrm c}$, where $U_{0\mathrm s}$ is the strahl speed and $w_{\mathrm c}$ is the thermal speed of the core electrons. These waves have a frequency of about half the local electron gyrofrequency. We also derive an analytic expression for the oblique FM/W instability for $β_{\mathrm c}\sim 1$. The comparison of our theoretical results with data from the \emph{Wind} spacecraft confirms the relevance of the oblique FM/W instability for the solar wind. The whistler heat-flux, ion-acoustic heat-flux, kinetic-Alfvén-wave heat-flux, and electrostatic electron-beam instabilities cannot fulfill the requirements for self-induced scattering of strahl electrons into the halo. We make predictions for the electron strahl close to the Sun, which will be tested by measurements from \emph{Parker Solar Probe} and \emph{Solar Orbiter}.

description: We propose a scheme for conditional quantum logic between two 3-state atoms that share a quantum data-bus such as a single mode optical field in cavity QED systems, or a collective vibrational state of trapped ions. Making use of quantum interference, our scheme achieves successful conditional phase evolution without any real transitions of atomic internal states or populating the quantum data-bus. In addition, it only requires common addressing of the two atoms by external laser fields.

Evidence for partial chiral symmetry restoration from pionic atoms

description: Extensive data on strong interaction effects in pionic atoms are analyzed with a density-dependent isovector scattering amplitude suggested recently by Weise to result from a density dependence of the pion decay constant. Most of the so-called `missing s-wave repulsion' is removed when adopting this approach, thus indicating a partial chiral symmetry restoration in dense matter. The resulting potentials describe quite well also elastic scattering of 20 MeV pions on Ca. Further tests with elastic scattering are desirable.

description: Random models of evolution are instrumental in extracting rates of microscopic evolutionary mechanisms from empirical observations on genetic variation in genome sequences. In this context it is necessary to know the statistical properties of empirical observables (such as the local homozygosity for instance). Previous work relies on numerical results or assumes Gaussian approximations for the corresponding distributions. In this paper we give an analytical derivation of the statistical properties of the local homozygosity and other empirical observables assuming selective neutrality. We find that such distributions can be very non-Gaussian.

title: An Analysis of Climate Change Adaptation in the Agricultural Sector of the Red River Delta, Viet Nam

description: Climate change is predicted to have several major impacts on Viet Nam and highly likely to lead to sea level rise in low lying areas such as the Red River Delta, a major agricultural region in the country’s north. This will cause changes to the environment, including more frequent and extreme floods, and increased salinity of soil and water, disrupting the water supply and causing dislocation of the economy. These impacts in turn increase the vulnerability of people in the Red River Delta. Viet Nam’s government has responded with a number of policies and legal documents that aim to enable adaptation to climate change in water, agriculture and industry. The aim of this study is to examine the climate change issues identified by stakeholders in the agricultural sector within the Red River Delta and analyse whether the selected policy and legal documents give appropriate support to the implementation of integrated water resources management (IWRM) in dealing with those issues. This study analysed five recent policies and legal documents relevant to the response to climate change in the Red River Delta to find out whether or not they match current practical needs. A conceptual framework was developed based on the two related theoretical constructs: IWRM and water governance. The framework enabled evaluation of these policies and legal documents using five criteria: resources and accountability; availability and communication of information and data; participation; sectoral integration; and flexibility. Overall, the conceptual framework aimed to determine how effectively the policies and legal documents address the need for adaptation in the context of climate change.

description: We present and analyse a new tidal disruption event (TDE), AT2017eqx at redshift z=0.1089, discovered by Pan-STARRS and ATLAS. The position of the transient is consistent with the nucleus of its host galaxy; it peaks at a luminosity of $L \approx 10^{44}$ erg s$^{-1}$; and the spectrum shows a persistent blackbody temperature $T \gtrsim 20,000$ K with broad H I and He II emission. The lines are initially centered at zero velocity, but by 100 days the H I lines disappear while the He II develops a blueshift of $\gtrsim 5,000$ km s$^{-1}$. Both the early- and late-time morphologies have been seen in other TDEs, but the complete transition between them is unprecedented. The evolution can be explained by combining an extended atmosphere, undergoing slow contraction, with a wind in the polar direction becoming visible at late times. Our observations confirm that a lack of hydrogen a TDE spectrum does not indicate a stripped star, while the proposed model implies that much of the diversity in TDEs may be due to the observer viewing angle. Modelling the light curve suggests AT2017eqx resulted from the complete disruption of a solar-mass star by a black hole of $\sim 10^{6.3} M_\odot$. The host is another quiescent, Balmer-strong galaxy, though fainter and less centrally concentrated than most TDE hosts. Radio limits rule out a relativistic jet, while X-ray limits at 500 days are among the deepest for a TDE at this phase.

title: A Process Theory of IT Risk Management Implementation
Creators: name: Azizi, Neda
Publisher: name: Griffith University
Year: 2020
Subjects: subject: IT
subject: risk management framework
subject: Information Technology

description: The study develops a process model of the implementation of IT risk management frameworks involving IT department individuals. The literature on IT risk management and specifically participation with IT risk management frameworks, is reviewed. The review indicates a need for process research to improve existing knowledge and practices in the domain of IT risk management. Specifically, the thesis addresses four research questions: (i) What IT culture could be identified during the implementation of ITRM for the first time? (ii) What factors and contextual conditions influence the implementation of ITRM? (iii) What are the processes IT managers go through when implementing ITRM within IT departments? (iv) How can these ITRM processes be depicted in a model? This qualitative study adopts a subjectivist epistemology, complemented with an interpretive paradigm and inductive reasoning. A series of nine case studies were designed around forty-two semi-structured in-depth interviews and were conducted to investigate how and why IT managers and their IT teams implemented risk management for the first time. The study focused on contextual and processual elements as well as the action of key players associated with implementation. The use of a Grounded theory− like qualitative analysis was particularly appropriate, generating a set of insights, issues, and propositions that addressed the critical individual and organisational elements involved in implementing IT risk management, elements to date largely overlooked in the risk management literature. The theory generated from the empirical findings suggests that the intentions and actions of IT department’s members (head of IT, senior IT management and operational IT groups), the processes they enact, as well as the organisational context into which they are implemented, critically influence IT risk management implementation. The findings provide new insights in relation to IT risk management implementation by considering IT individual culture. The thesis conceptualises IT risk management implementation as a cultural process through which IT managers socially construct the meanings and purposes of their work activities. These findings suggest a dynamic approach to implementing IT risk management framework — one that considers the interaction over time of intentions, context, process, and action around risk management frameworks. The research develops a substantive theory (Gregor, 2006) involving a schematic model involving five sub-process and a set of theoretical propositions. The thesis discusses the propositions by way of reference to the literature thereby enhancing the credibility and generalisability of theory building from case research. The last section presents an evaluation of the resulting theory by following the guidelines introduced by Sjøberg et al. (2008) for building behavioural theories in software engineering.

Degenerations of K3, Orientifolds and Exotic Branes

description: A recently constructed limit of K3 has a long neck consisting of segments, each of which is a nilfold fibred over a line, that are joined together with Kaluza-Klein monopoles. The neck is capped at either end by a Tian-Yau space, which is non-compact, hyperkahler and asymptotic to a nilfold fibred over a line. We show that the type IIA string on this degeneration of K3 is dual to the type I$'$ string, with the Kaluza-Klein monopoles dual to the D8-branes and the Tian-Yau spaces providing a geometric dual to the O8 orientifold planes. At strong coupling, each O8-plane can emit a D8-brane to give an O8$^*$ plane, so that there can be up to 18 D8-branes in the type I$'$ string. In the IIA dual, this phenomenon occurs at weak coupling and there can be up to 18 Kaluza-Klein monopoles in the dual geometry. We consider further duals in which the Kaluza-Klein monopoles are dualised to NS5-branes or exotic branes. A 3-torus with $H$-flux can be realised in string theory as an NS5-brane wrapped on $T^3$, with the 3-torus fibred over a line. T-dualising gives a 4-dimensional hyperkahler manifold which is a nilfold fibred over a line, which can be viewed as a Kaluza-Klein monopole wrapped on $T^2$. Further T-dualities then give non-geometric spaces fibred over a line and can be regarded as wrapped exotic branes. These are all domain wall configurations, dual to the D8-brane. Type I$'$ string theory is the natural home for D8-branes, and we dualise this to find string theory homes for each of these branes. The Kaluza-Klein monopoles arise in the IIA string on the degenerate K3. T-duals of this give exotic branes on non-geometric spaces.

description: Quantum random walks have been much studied recently, largely due to their highly nonclassical behavior. In this paper, we study one possible route to classical behavior for the discrete quantum random walk on the line: the use of multiple quantum ``coins'' in order to diminish the effects of interference between paths. We find solutions to this system in terms of the single coin random walk, and compare the asymptotic limit of these solutions to numerical simulations. We find exact analytical expressions for the time-dependence of the first two moments, and show that in the long time limit the ``quantum mechanical'' behavior of the one-coin walk persists. We further show that this is generic for a very broad class of possible walks, and that this behavior disappears only in the limit of a new coin for every step of the walk.
