Development and testing of a field instrument for research into the study of attitudes and preferences involved in the purchase of homes
Creators: name: Sim, Ah Ba
Publisher: name: University of British Columbia
Year: 2012

description: The object of the thesis was to develop a field instrument for the determination of aesthetic tastes and preferences among various social groups. The instrument has been developed for use in research on attitudes and preferences involved in the purchase of homes. The instrument was constructed as a visual attitude scale, consisting of three house photographs graduated along a social class continuum to represent the lower, middle, and upper scale categories; and will be developed on the assumption that people can consistently discriminate among house photographs on the basis of perceived social class of occupant families. The three house photographs were derived from a rating process in the field which used 60 respondents to rate a set of 30 carefully selected house photographs among three social class categories. The house photographs associated most with each of the three categories were selected to represent each social stratum in the visual attitude scale. Use of the visual attitude scale in conjunction with the Semantic Differential and open-end questions was proposed as a means to determine differences in aesthetic tastes and preferences and, also, other attitudes involved in the decision making process to buy a home. The actual utility and validity of the field instrument cannot be established here, but must be the object of further research. The study did reveal, however, a high degree of consistency of ratings by respondents from different social class backgrounds and, therefore, provided face validation for the assumptions underlying the construction of the field instrument.
Pulmonary arterial wave intensity analysis in health and disease.
Creators: name: Dwyer, NB
Publisher: name: University Of Tasmania
Year: 2023

description: Wave intensity analysis (WIA) is a time-domain technique utilising high fidelity pressure and velocity measurements to determine the intensity, direction, type and timing of waves that may simultaneously exist. Travelling wavefronts represent elemental units of energy transmitted within and between the heart and blood vessels. Thus, WIA allows us to study ventricular-arterial interactions providing information on ventricular performance and the state of the circulation. In the pulmonary circulation WIA allows the study of upstream and downstream events that influence net pulmonary arterial blood flow. WIA was performed in the pulmonary arteries of anaesthetised open-chest sheep, determining a normal mean wave speed of 2.1 ms-1. Whilst wave reflection was minimal in healthy resting pulmonary arteries, two minor but clearly discernible backward travelling waves were identified that serve as important physiological markers. The first was an early systolic backward expansion wave representing open-end reflection from a site approximately 3 cm downstream, most likely from the main pulmonary bifurcation, and would serve to augment flow out of the right ventricle. The second was a late systolic backward compression wave representing closed-end reflection from a site approximately 20 cm downstream, most likely from the pulmonary microcirculation, and would serve to oppose flow out of the right ventricle. The open-end reflection was enhanced by increased pulmonary blood flow or circulating blood volume. With pulmonary vasoconstriction or obstruction, WIA was able to accurately determine the distance to the newly developed closed-end reflection site from which a backward compression arrives in mid-systole and opposes flow out of the right ventricle. In human volunteers with normal or diseased pulmonary vasculature, wave speed was shown to increase linearly with pulmonary vascular resistance. The difficulties in reproducing instantaneous pulmonary blood velocity accurately invivo limited assessment of reflected waves.
The effect of transcranial magnetic stimulation on pain and detection thresholds in both healthy individuals and individuals suffering from chronic pain
Creators: name: Colquhoun, S

description: Chronic pain is a complex phenomenon that is thought to affect between 17 and 22% of the Australian population. The complexities of chronic pain and the many different contributing factors to this condition, makes the relief of the symptomatic experience of pain difficult in many cases. Although there are a wide variety of treatment options available with varying degrees of invasiveness, often these options alone and in combination do not provide adequate pain relief for chronic pain sufferers. There is some evidence that repetitive transcranial magnetic stimulation (rTMS) can alleviate the experience of chronic pain in individuals with medication-resistant chronic pain. The mechanisms by which rTMS may induce pain relief, however, are unknown. Consequently, there is a need to further explore the underlying mechanisms contributing to the analgesic effect that rTMS displays. The present research examines the ability of TMS to directly influence peripheral sensations. The first two studies compared the effects of a single session of low frequency (1 Hz) TMS and high frequency (20 Hz) rTMS on thermal sensory thresholds in healthy individuals. High frequency rTMS was found to produce greater alterations in sensory thresholds than low frequency rTMS. A third study was carried out examining the effect of a single session of high frequency (20 Hz) rTMS on the sensory thresholds of individuals suffering from chronic pain and to measure rTMS-induced changes in their experience of pain. Overall, this research revealed a limited degree of sensory alteration following low frequency rTMS in which only cold detection thresholds were significantly modified. High frequency rTMS, however, significantly altered cold detection and pain thresholds for healthy individuals, and cold detection, pain and heat pain thresholds were significantly altered for individuals suffering from chronic pain. In addition, individuals suffering from chronic pain reported a significant reduction in their experience of pain following high frequency rTMS. The finding that rTMS can have a direct effect on sensory thresholds has implications for the therapeutic use of rTMS in the relief of chronic pain and provides scope for further investigation into the long-term effects of these alterations and the use of multiple sessions of rTMS in reducing the experience of chronic pain.

description: We show that if $K$ is a knot in $S^3$ and $Σ$ is a bridge sphere for $K$ with high distance and $2n$ punctures, the number of perturbations of $K$ required to interchange the two balls bounded by $Σ$ via an isotopy is $n$. We also construct a knot with two different bridge spheres with $2n$ and $2n-1$ bridges respectively for which any common perturbation has at least $3n-1$ bridges. We generalize both of these results to bridge surfaces for knots in any 3-manifold.

description: Tin doped indium oxide (ITO) thin films provide excellent transparency and conductivity for electrodes in displays and photovoltaic systems. Current advances in producing printable ITO inks are reducing the volume of wasted indium during thin film patterning. However, their applicability to flexible electronics is hindered by the need for high temperature processing that results in damage to conventional polymer substrates. Here, we detail the conditions under which laser heating can be used as a replacement for oven and furnace treatments. Measurements of the optical properties of both the printed ITO film and the polymer substrate (polyethylene terephthalate, PET) identify that in the 1.5–2.0 μm wavelength band there is absorption in the ITO film but good transparency in PET. Hence, laser light that is not absorbed in the film does not go on to add a deleterious energy loading to the substrate. Localization of the energy deposition in the film is further enhanced by using ultrashort laser pulses (~1 ps) thus limiting heat flow during the interaction. Under these conditions, laser processing of the printed ITO films results in an improvement of the conductivity without damage to the PET. © 2019, The Author(s).
Evolution equation for the B-meson distribution amplitude in the heavy-quark effective theory in coordinate space
Creators: name: Kawamura, Hiroyuki

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The B-meson distribution amplitude (DA) is defined as the matrix element of a quark-antiquark bilocal light-cone operator in the heavy-quark effective theory, corresponding to a long-distance component in the factorization formula for exclusive B-meson decays. The evolution equation for the B-meson DA is governed by the cusp anomalous dimension as well as the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi-type anomalous dimension, and these anomalous dimensions give the "quasilocal" kernel in the coordinate-space representation. We show that this evolution equation can be solved analytically in the coordinate-space, accomplishing the relevant Sudakov resummation at the next-to-leading logarithmic accuracy. The quasilocal nature leads to a quite simple form of our solution which determines the B-meson DA with a quark-antiquark light-cone separation $t$ in terms of the DA at a lower renormalization scale $μ$ with smaller interquark separations $zt$ ($z \leq 1$). This formula allows us to present rigorous calculation of the B-meson DA at the factorization scale $\sim \sqrt{m_b Λ_{\rm QCD}}$ for $t$ less than $\sim 1$ GeV^{-1}, using the recently obtained operator product expansion of the DA as the input at $μ\sim 1$ GeV. We also derive the master formula, which reexpresses the integrals of the DA at $μ\sim \sqrt{m_b Λ_{\rm QCD}}$ for the factorization formula by the compact integrals of the DA at $μ\sim 1$ GeV.

description: The handling of droplets in a controlled manner is essential to numerous technological and scientific applications. In this work, we present a new open-surface platform for droplet manipulation based on an array of bendable nozzles that are dynamically controlled by a magnetic field. The actuation of these nozzles is possible thanks to the magnetically responsive elastomeric composite which forms the tips of the nozzles; this is fabricated with Fe3O4 microparticles embedded in a polydimethylsiloxane matrix. The transport, mixing, and splitting of droplets can be controlled by bringing together and separating the tips of these nozzles under the action of a magnet. Additionally, the characteristic configuration for droplet mixing in this platform harnesses the kinetic energy from the feeding streams; this provided a remarkable reduction of 80% in the mixing time between drops of liquids about eight times more viscous than water, i.e., 6.5 mPa/s, when compared against the mixing between sessile drops of the same fluids. © 2019 by the authors.
Enhancing automotive stability control with artificial neural networks
Creators: name: Butler, DA
Publisher: name: University Of Tasmania
Year: 2023

description: Many studies of automotive crash statistics have shown that driver error is a major cause of accident and injury on the roads worldwide. This has lead to the development of many active control systems to aid the driver during panic maneuvers, such as antilock braking systems. Nonetheless, there has been a slow growth in the control methodology of these systems, with wheel speed regulation based on the information derived from a small number of sensors the norm across all past and present systems. To achieve greater performance gains, it is important to control more vehicle parameters and obtain vehicle state information from larger sensor arrays. Problems arise using traditional control methodology, as additional variables create exponential increases in control algorithm complexity, and in computational requirements. Artificial neural networks (ANN) are presented in literature as an artificial intelligence solution to approaching problems. Significant benefits include, the ability to model highly non-linear and complex systems, capacity to incorporate many model inputs and outputs, low computational requirements and capability for self-learning from observed data. However, previous work has largely been limited to simulation or very narrow practical testing, from which it is difficult to draw useful conclusions. This thesis addresses these problems by developing two new ANN systems, implemented in broad practical tests. The first uses suspension and wheel speed vibration to intelligently predict road surface conditions, which is a major performance limitation in all current systems. The second models complex vehicle dynamics through a large sensor array and ANN process optimisation to implement intelligent traction control. This method determines the optimal driven wheel speed for maximum acceleration in the driver's desired direction, in a process that is generic and adaptable to current and future active control systems. All results are derived from a real test vehicle, which was adapted for this investigation. This included the installation of chassis and engine sensors, data acquisition and control systems, engine management hardware and user interfaces, as well as constructing ANN models and controllers in the NI LabVIEW language. The positive outcomes of this work are a step towards establishing new methods of active vehicle control on a statistical and quantitative basis.
Immobile element geochemistry of altered volcanics and exhalites at the Thalanga deposit, North Queensland
Creators: name: Hermann, W
Publisher: name: University Of Tasmania
Year: 2023

description: Thalanga is a deformed and metamorphosed volcanic hosted massive sulphide deposit consisting of several thin, stratiform semi-connected lenses located at a sub-vertically dipping contact between rhyolite and dacite formations. Rocks composed of quartzmagnetite- barite and chlorite-tremolite-carbonate, which have previously been interpreted to be exhalites, exist in intimate stratabound association with sulphides, particularly in the western lenses. Rhyolites stratigraphically beneath the deposit are extensively hydrothermally altered with a stratabound stringer zone of intense silicification containing 4-20% pyrite in the immediate footwall of the sulphide lenses, grading outwards and downwards through progressively weaker zones of qu~rtzchlorite- sericite and quartz-sericite alteration. Titanium, aluminium and zirconium remained chemically immobile during alteration, and subsequent metamorphism. These immobile elements permit identification of the volcanic precursors of altered rocks and quantitative estimation of the chemical changes due to alteration. Large gains of silica, iron, sulphur and loss of sodium are indicated for the zone of most intense footwall alteration. Chlorite-tremolite-carbonate rocks associated with sulphides have immobile element contents and ratios identical to those of altered footwall rhyolites and their chemistry is consistent with a derivation from rhyolite involving large gains of calcium, magnesium, C02 and losses of silica and sodium. They are re-interpreted to be metamorphosed chlorite-carbonate alteration assemblages which probably formed in permeable rhyolitic volcaniclastics by hydrothermal fluid and sea water mixing at the upper and outer parts of a mineralising sub-marine hydrothermal system. Magnetite-quartzites have very low immobile element contents and may be the only true exhalites at Thalanga, other than massive barite and base metal sulphide assemblages.

description: We study the superfluid to Mott-insulator (SF-MI) transition of hardcore bosons in commensurate superlattices in two and three dimensions. We focus on the special case where the superlattice has period two and the system is at half filling. We obtain exact numerical results by using the stochastic series expansion (SSE) algorithm, and compute various properties of the system, such as the ground-state energy, the fraction of bosons in the zero-momentum mode, the superfluid density, and the compressibility. With finite-size scaling, we find the critical points of the phase transition. We also explore the extent to which several approximate solutions such as mean-field theory, with and without spin-wave corrections, can help one gain analytical insight into the behavior of the system in the vicinity of the phase transition.

The geology of the Royal George area
Creators: name: Beattie, RD
Publisher: name: University Of Tasmania
Year: 2023

description: The Silurian (?) to Lower Devonian Mathinna Beds have been folded during the Tabberabberan Orogeny and later intruded by the Royal George Granite Complex of probable early Late Devonian age. The Complex is a high level stock, with sharp margins and a narrow contact metamorphic aureole. Its major rock types are coarse-grained granites, porphyries and microgranites, which are alkali-rich and have a low K/Rb ratio. The latter is suggestive of strong differentiation. Low grade tin mineralization is associated with the Complex. A Permian marine and non-marine succession is unconformable on the Mathinna Beds and granite. It is only 150 feet thick over a basement high near Royal George, but thickens to 406 feet at St. Pauls Dome to the west. The basement high may have been above sea level until the time of deposition of the Grange Mudstone Correlate. Silllike (?) Jurassic dolerite intrudes both the Permian strata and the overlying Triassic non-marine, arenaceous sediments. Fluvial and lacustrine (?) sediments may have been deposited behind Tertiary basalt which dammed (?) the South Esk River near Avoca.

description: We present an energy-conserving multiple-relaxation-time finite difference lattice Boltzmann model for compressible flows. This model is based on a 16-discrete-velocity model. The collision step is first calculated in the moment space and then mapped back to the velocity space. The moment space and corresponding transformation matrix are constructed according to the group representation theory. Equilibria of the nonconserved moments are chosen according to the need of recovering compressible Navier-Stokes equations through the Chapman-Enskog expansion. Numerical experiments showed that compressible flows with strong shocks can be well simulated by the present model. The used benchmark tests include (i) shock tubes, such as the Sod, Lax, Sjogreen, Colella explosion wave and collision of two strong shocks, (ii) regular and Mach shock reflections, and (iii) shock wave reaction on cylindrical bubble problems. The new model works for both low and high speeds compressible flows. It contains more physical information and has better numerical stability and accuracy than its single-relaxation-time version.

description: A gravitational potential in the relativistic case is introduced as an alternative to Wald's potential used by Verlinde, which reproduces the familiar entropy/area relation S=A/4 (in the natural units) when Verlinde's idea is applied to the black hole case. Upon using the equipartition rule, the correct form of the Komar mass (energy) can also be obtained, which leads to the Einstein equations. It is explicitly shown that our entropy formula agrees with Verlinde's entropy variation formula in spherical cases. The stationary space-times, especially the Kerr-Newman black hole, are then discussed, where it is shown that the equipartition rule involves the reduced mass, instead of the ADM mass, on the horizon of the black hole.
description: 13 pages, a discussion is added into section III in the new version, which explicitly shows that our entropy formula agrees with Verlinde's entropy variation formula in spherical cases. The abstract, introduction and conluding remarks also have been revised. Some typing mistakes in old versions have been corrected. v4: minor modifications, match the published version.

Deformation and metamorphism of the Aileu formation, East Timor
Creators: name: Berry, RF
Publisher: name: University Of Tasmania
Year: 2023

description: A 10 km wide coastal strip of the Aileu Formation was mapped in detail. This section of the north coast of Timor lies 70 km south of a recently active island arc and was chosen as a potential type example of the deformation style in an arc-continent collision zone. In addition a brief study was made of the petrography and chemistry of altered igneous rocks from this coastal strip and igneous rocks of a similar age from other regions in East Timor. The Aileu Formation is composed of metamorphosed shales, siltstones and arenites with minor limestones and basites. The metamorphic grade of this formation is zoned from lower greenschist facies in the southwest to upper almandine-amphibolite facies in the east. Five structural phases are recognised. The first generation isa cleavage or schistosity which predates the single prograde metamorphism. No folds were found associated with this foliation and its significance is unknown. The second deformation phase occurred in the Late Miocene. It syn- and post-dates the prograde metamorphic event, produced tight folds and transposed the compositional layering and early cleavage on all scales. The last three deformation phases produced open to gentle macroscopic folds. Correlations with structural data from other formations suggest the third and fourth phases occurred in the Late Miocene and the fifth deformation occurred in the Early Pleistocene. The major high angle faults, which form the boundaries of the Aileu Formation, were also active in the Early Pleistocene. The amphibolites and altered dolerites of the Aileu Formation are transitional, in composition, between alkaline and tholeiitic basalts. Permian and Mesozoic basalts and dolerites from other regions in East Timor include both alkaline and tholeiitic compositions. All these igneous rocks are characteristic of continental rift valleys and ocean islands. However the associated sedimentary rocks were deposited on a continental shelf or slope. There is no evidence that the Aileu Formation or the Permian and Mesozoic formations were not formed on the Australian continental margin. The geology of Timor is consistent with its evolution as a rift valley in the Late Palaeozoic and Early Mesozoic, and a trailing margin from the Cretaceous to the Early Miocene. Structural data suggests a Late Miocene arc-continent collision. There has been post-orogenic uplift and minor additional deformation in the Plio-Pleistocene. Comparison of Papua New Guinea with Timor suggests that the mobile belt in arc-continent collisions is characterised by medium pressure metamorphism, relatively coherent deformation style, and a short history of orogenic activity. Little evidence of thrusting or imbrication has been uncovered and their importance as deformation processes in this environment remains speculative.
Small-scale instabilities in dynamical systems with sliding

description: We demonstrate with a minimal example that in Filippov systems (dynamical systems governed by discontinuous but piecewise smooth vector fields) stable periodic motion with sliding is not robust with respect to stable singular perturbations. We consider a simple dynamical system that we assume to be a quasi-static approximation of a higher-dimensional system containing a fast stable subsystem. We tune a system parameter such that a stable periodic orbit of the simple system touches the discontinuity surface: this is the so-called grazing-sliding bifurcation. The periodic orbit remains stable, and its local return map becomes piecewise linear. However, when we take into account the fast dynamics the local return map of the periodic orbit changes qualitatively, giving rise to, for example, period-adding cascades or small-scale chaos.

title: 'Shades of the prison-house': the disciplining of the Victorian literary orphan
Creators: name: Peters, Laura Lynn
Publisher: name: University of Kent
Year: 2021

description: The Victorian fictive orphan as an aesthetic trope hypostatises a cultural moment in which the bourgeois ideology of the family attains a socio-political universal status. The thesis considers how the mode of narrating (what I will call the penal narrative) the oprhan in mid-Victorian literature reflects the ideology of the age: this penal narrative is a product of the Grand Narrative of the family which surveys and attempts to neutralise the orphan. This neutralisation manifests itself in the production of orphan fictional autobiographies which are increasingly confessional in nature. The 'Introduction' undertakes to contextualise the fictive orphan in three ways: cultural-historically through a consideration of the rise of the bourgeois ideology of the family; aesthetically through a consideration of Worsworthian Romanticism which fetishised the child; and theoretically through a consideration of Girard's notion of the scapegoat, Althusser's concept of ideology and Foucault's documentation of disciplinary techniques. The first chapter on Victorian Orphan Popular Literature deals with the production of the orphan as trope; establishing the orphan as representative of both a textual attitude and of the discursive regime of the period which articulates this new structure of feeling. This chapter considers how the discourse of orphanhood, in intersecting with other Victorian cultural discourses (especially high culture, religion and popular literature) forms a literary subgenre. The second chapter will analyse Dickens's Oliver Twist and The Old Curiosity Shop in which the orphans function primarily as redemptive child-orphans who do not grow. The third chapter deals with the novels Jane Eyre, Vanity Fair and David Copperfield. This chapter reads these narratives as penal narratives - functioning to neutralise and assimilate the orphan. The resistance offered by the orphan figures arises from their spiritual power inherited from their Romantic aesthetic genealogy. Chapter Four, in considering Villette and Little Dorrit, identifies a shift in the function of fictional autobiographical narrative from the creation to confession. In these narratives the notion of orphanhood is also extended to a socio-political status as Lucy Snowe and Arthur Clenman are orphan outcasts bereft of the family of the nation-state. This chapter also explore to what extent these narratives interpellate the reader into an agent for bourgeois ideology. Chapter Five reads George Eliot's Silas Marner as a hybrid between high art and fairy tale which endeavours to mythologise the notion of family (inh a Barthesian notion of myth). This chapter will form the conclusion of the thesis in its attempt to extend the notion of orphan as a cultural trope and ultimately an imperial trope.

description: Semi-linear response theory determines the absorption coefficient of a driven system using a resistor network calculation: Each unperturbed energy level of a particle in a vibrating trap, or of an electron in a mesoscopic ring, is regarded as a node ($n$) of the network; The transition rates ($w_{mn}$) between the nodes are regarded as the elements of a random matrix that describes the network. If the size-distribution of the connecting elements is wide (e.g. log-normal-like rather than Gaussian-like) the result for the absorption coefficient differs enormously from the conventional Kubo prediction of linear response theory. We use a generalized variable range hopping scheme for the analysis. In particular we apply this approach to obtain practical approximations for the conductance of mesoscopic rings. In this context Mott's picture of diffusion and localization is revisited.

description: We study the edge states in graphene in the presence of a magnetic field perpendicular to the plane of the lattice. Most of the works done so far discuss the edge states in either zigzag or armchair edge graphene considering an isotropic electron hopping. In practice, graphene can have mixture of armchair and zigzag edges and the electron hopping can be anisotropic, which is the subject of this article. We predict that the mixed edges smear the enhanced local density of states (LDOS) at E=0 of the zigzag edge and, on the other hand, the anisotropic hopping gives rise to the enhanced LDOS at E=0 in the armchair edge. The behavior of the LDOS can be studied using scanning tunneling microscopy (STM) experiments. We suggest that care must be taken while interpreting the STM data. It is because the clear distinction between the zigzag edge (enhanced LDOS at E=0) and armchair edge (suppressed LDOS at E=0) can be lost if the hopping is not isotropic and if the edges are mixed.
A whole of system approach to analysis of security in RFID Systems using an integrated layered and partitioned reference model
Creators: name: Mirowski, L
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis proposes the use of a 'whole of system' approach to the analysis of security in Radio Frequency Identification (RFID) systems and introduces a reference model for this purpose. It illustrates the advantages of this approach in the context of detecting clone tags within RFID systems, including the specific example of a pharmaceutical supply chain. It compares the results from using the proposed model with those from previous work that adopted a more localised approach (Rotter 2008; Mitrokotsa et al. 2010). In order to enable the 'whole of system' approach, a domain model for RFID systems is introduced and a simulator based on this is implemented. Interesting insights arising from simulator results are confirmed through laboratory experiments. The reference model proposed consists of the three horizontal layers suggested by previous authors: real world, RFID and strategic (Mitrokotsa et al. 2008, 2009), but adds vertical security partitions for such things as the problem context. This provides a structure that allows existing analysis methods from any appropriate source to be applied systematically, such that their results are integrated across the whole system. It is shown that this provides for the analysis of not only the security requirements of the whole system but also, where in the system it is practicable to place measures that achieve these requirements. The domain model introduced comprises a logical view of RFID components and a data view of the associations and features that characterise the component interactions. The model's controlled vocabulary allows the domain constructs in RFID systems to be identified and described. A simulator, which has been validated for preliminary 'whole of system' analysis and is based on this domain model, allows experimentation with systems via an application programming interface (API). Work suggested by the reference model is reported as simulation results, and confirmed by laboratory experimentation using Class-One Generation-Two RFID equipment. Whereas Juels (2005) showed that tags of this standard can be reprogrammed so that they can be authenticated by a reader, the results in this thesis illustrate how readers can be reprogrammed to expose clone tags, thereby contributing an additional security solution. This thesis addresses an analysis gap in the RFID security field by introducing a 'whole of system' approach made possible by the proposed reference model. The results illustrate that the effectiveness of security in RFID systems can be improved by employing a range of individual analysis methods integrated into this model.

description: We describe the realization of a 5 km free space coherent optical link through the turbulent atmosphere between a telescope and a ground target. We present the phase noise of the link, limited mainly by atmospheric turbulence and mechanical vibrations of the telescope and the target. We discuss the implications of our results for applications, with particular emphasis on optical Doppler ranging to satellites and long distance frequency transfer.

description: \There can be no purpose more inspiring than to begin the age of restoration reweaving the wondrous diversity of life that still surrounds us\" ‚Äö- E.O Wilson. Ecological restoration is an expensive time consuming and labour intensive activity. It is therefore important to understand the potential for disturbed natural ecosystems to recover without the need for intervention. This project investigates the rate of vegetation and soil recovery from different types of disturbance at 18 sites within four major ecosystems (grassy dry sclerophyll wet sclerophyll and rainforest) in Tasmania. All sites have a known disturbance history (type and age). At each site randomly located quadrats were placed in the disturbed and control areas and the percentage cover of species bare ground and litter estimated using a modified Braun-Blanquet scale. The pH N P C of surface soils from the subset of these quadrats was measured. Topographic and climatic data were obtained at the site level. Global non-metric multi-dimensional scaling was performed on the presence/absence data for all taxa. Bray-Curtis dissimilarity matrices were produced and these were used to examine similarities and dissimilarities between disturbed and control areas. Vectors were fitted for all variables and significance determined by 1000 randomisations. Sorted tables were used to indicate the abundance and presence or absence of taxa at site and ecosystem levels. Relationships between independent variables and the mean distances between control and disturbance vegetation and soils were determined at the site level. The type of initial disturbance (superficial or severe) rather than the time since cessation of the initial disturbance or other factors was the best single predictor of the recovery of both vegetation and soil. Restoration effort should be directed towards areas that are known (as determined by site history) to have been subjected to extensive soil and vegetation disturbance."

description: Projections of global warming in Africa are generally associated with increasing aridity and decreasing water availability. However, most freshwater assessments focus on single hydroclimatic indicators (e.g., runoff, precipitation, or aridity), lacking analysis on combined changes in evaporative demand, and water availability on land. There remains a high degree of uncertainty over water implications at the basin scale, in particular for the most water-consuming sector—food production. Using the Budyko framework, we perform an assessment of future hydroclimatic change for the 50 largest African basins, finding a consistent pattern of change in four distinct regions across the two main emission scenarios corresponding to the Paris Agreement, and the business as usual. Although the Paris Agreement is likely to lead to less intense changes when compared to the business as usual, both scenarios show the same pattern of hydroclimatic shifts, suggesting a potential roadmap for hydroclimatic adaptation. We discuss the social-ecological implications of the projected hydroclimatic shifts in the four regions and argue that climate policies need to be complemented by soil and water conservation practices to make the best use of future water resources. ©2019.

description: Natural pest and weed regulation are essential for agricultural production, but the spatial distribution of natural enemies within crop fields and its drivers are mostly unknown. Using 28 datasets comprising 1,204 study sites across eight Western and Central European countries, we performed a quantitative synthesis of carabid richness, activity densities and functional traits in relation to field edges (i.e. distance functions). We show for the first time that distance functions of carabids strongly depend on carabid functional traits, crop type and, to a lesser extent, adjacent non-crop habitats. Richness of both predators and granivores and activity densities of small and granivorous species decreased towards field interiors, whereas the densities of large species increased. We found strong distance decays in maize and vegetables whereas richness and densities remained more stable in cereals, oilseed crops and legumes. We conclude that carabid assemblages in agricultural landscapes are driven by the complex interplay of crop types, adjacent non-crop habitats and further landscape parameters with great potential for targeted agroecological management. In particular, our synthesis indicates that a higher edge-interior ratio can counter the distance decay of carabid richness per field and thus likely benefits natural pest and weed regulation, hence contributing to agricultural sustainability.

description: We prove a structure theorem for finite-dimensional indefinite-signature metric 3-Lie algebras admitting a maximally isotropic centre. This algebraic condition indicates that all the negative-norm states in the associated Bagger-Lambert theory can be consistently decoupled from the physical Hilbert space. As an immediate application of the theorem, new examples beyond index 2 are constructed. The lagrangian for the Bagger-Lambert theory based on a general physically admissible 3-Lie algebra of this kind is obtained. Following an expansion around a suitable vacuum, the precise relationship between such theories and certain more conventional maximally supersymmetric gauge theories is found. These typically involve particular combinations of N=8 super Yang-Mills and massive vector supermultiplets. A dictionary between the 3-Lie algebraic data and the physical parameters in the resulting gauge theories will thereby be provided.
