description: We use Fabry-Perot absorption line imaging spectroscopy to measure radial velocities using the Ca II 8542 line in 3360 stars towards three lines of sight in the Milky Way's bar: Baade's Window and offset position at (l,b) ~ (+-5.0, -3.5). This sample includes 2488 bar red clump giants, 339 bar M/K-giants, and 318 disk main sequence stars. We measure the first four moments of the stellar velocity distribution of the red clump giants, and find it to be symmetric and flat-topped. We also measure the line-of-sight average velocity and dispersion of the red clump giants as a function of distance in the bar. We detect stellar streams at the near and far side of the bar with velocity difference > 30 km/s at l = +-5, but we do not detect two separate streams in Baade's Window. Our M-giants kinematics agree well with previous studies, but have dispersions systematically lower than those of the red clump giants by ~ 10 km/s. For the disk main sequence stars we measure a velocity dispersion of ~ 45 km/s for all three lines-of-sight, placing a majority of them in the thin disk within 3.5 kpc of the Sun, associated with the Sagittarius spiral arm. We measure the equivalent widths of the Ca II 8542 line that can be used to infer metallicities. We find indications of a metallicity gradient with Galactic longitude, with greater metallicity in Baade's Window. We find the bulge to be metal-rich, consistent with some previous studies.

description: The individual care plan is a collaborative process used in the management ofmanaging long-term health conditions in which people and health professionals identify and discuss problems caused by or related to the person's health condition, and develop a plan to ad-dress them. We elaborated a scoping review with the objective to understand the extent and type of evidence in relation to the impact of individual care plan management on health outcomes in people with multiple long-term health problems in the community.

description: We study a generalized Pólya urn model with two types of ball. If the drawn ball is red, it is replaced together with a black ball, but if the drawn ball is black it is replaced and a red ball is thrown out of the urn. When only black balls remain, the roles of the colors are swapped and the process restarts. We prove that the resulting Markov chain is transient but that if we throw out a ball every time the colors swap, the process is recurrent. We show that the embedded process obtained by observing the number of balls in the urn at the swapping times has a scaling limit that is essentially the square of a Bessel diffusion. We consider an oriented percolation model naturally associated with the urn process, and obtain detailed information about its structure, showing that the open subgraph is an infinite tree with a single end. We also study a natural continuous-time embedding of the urn process that demonstrates the relation to the simple harmonic oscillator; in this setting, our transience result addresses an open problem in the recurrence theory of two-dimensional linear birth and death processes due to Kesten and Hutton. We obtain results on the area swept out by the process. We make use of connections between the urn process and birth--death processes, a uniform renewal process, the Eulerian numbers, and Lamperti's problem on processes with asymptotically small drifts; we prove some new results on some of these classical objects that may be of independent interest. For instance, we give sharp new asymptotics for the first two moments of the counting function of the uniform renewal process. Finally, we discuss some related models of independent interest, including a "Poisson earthquakes" Markov chain on the homeomorphisms of the plane.

description: We investigate a class of theories involving a symmetric two-tensor field in Minkowski spacetime with a potential triggering spontaneous violation of Lorentz symmetry. The resulting massless Nambu-Goldstone modes are shown to obey the linearized Einstein equations in a fixed gauge. Imposing self-consistent coupling to the energy-momentum tensor constrains the potential for the Lorentz violation. The nonlinear theory generated from the self-consistent bootstrap is an alternative theory of gravity, containing kinetic and potential terms along with a matter coupling. At energies small compared to the Planck scale, the theory contains general relativity, with the Riemann-spacetime metric constructed as a combination of the two-tensor field and the Minkowski metric. At high energies, the structure of the theory is qualitatively different from general relativity. Observable effects can arise in suitable gravitational experiments.

description: Many strongly correlated electronic materials, including high-temperature superconductors, colossal magnetoresistance and metal-insulator-transition (MIT) materials, are inhomogeneous on a microscopic scale as a result of domain structure or compositional variations. An important potential advantage of nanoscale samples is that they exhibit the homogeneous properties, which can differ greatly from those of the bulk. We demonstrate this principle using vanadium dioxide, which has domain structure associated with its dramatic MIT at 68 degrees C. Our studies of single-domain vanadium dioxide nanobeams reveal new aspects of this famous MIT, including supercooling of the metallic phase by 50 degrees C; an activation energy in the insulating phase consistent with the optical gap; and a connection between the transition and the equilibrium carrier density in the insulating phase. Our devices also provide a nanomechanical method of determining the transition temperature, enable measurements on individual metal-insulator interphase walls, and allow general investigations of a phase transition in quasi-one-dimensional geometry.

description: We investigate the fitness advantage associated with the robustness of a phenotype against deleterious mutations using deterministic mutation-selection models of quasispecies type equipped with a mesa shaped fitness landscape. We obtain analytic results for the robustness effect which become exact in the limit of infinite sequence length. Thereby, we are able to clarify a seeming contradiction between recent rigorous work and an earlier heuristic treatment based on a mapping to a Schrödinger equation. We exploit the quantum mechanical analogy to calculate a correction term for finite sequence lengths and verify our analytic results by numerical studies. In addition, we investigate the occurrence of an error threshold for a general class of epistatic landscape and show that diminishing epistasis is a necessary but not sufficient condition for error threshold behavior.

description: In the minimal supersymmetric standard model the R-parity violating interactions can trigger various exotic three-body decays for the top quark, which may be accessible at the LHC. In this work we examine the R-violating decays t-> c X_1 X_2, which include the tree-level processes t-> c l^-_i l^+_j (l_i=e, mu, tau) and t->c d_i \bar{d}_j (d_i=d, s, b), as well as the loop induced processes t->c g X (X=g, γ, Z, h). We find that the hereto weakly constrained R-violating couplings can render the decay branching ratios quite sizable, some of which already reach the sensitivity of the Tevatron collider and can be expored at the LHC with better sensitivity.

description: The importance of a node in a directed graph can be measured by its PageRank. The PageRank of a node is used in a number of application contexts - including ranking websites - and can be interpreted as the average portion of time spent at the node by an infinite random walk. We consider the problem of maximizing the PageRank of a node by selecting some of the edges from a set of edges that are under our control. By applying results from Markov decision theory, we show that an optimal solution to this problem can be found in polynomial time. Our core solution results in a linear programming formulation, but we also provide an alternative greedy algorithm, a variant of policy iteration, which runs in polynomial time, as well. Finally, we show that, under the slight modification for which we are given mutually exclusive pairs of edges, the problem of PageRank optimization becomes NP-hard.

\Strategising\" and the career development of women : a case study of a department in the Tasmanian Public Service"
Creators: name: Milewicz, Elizabeth Dorothy
Publisher: name: University Of Tasmania
Year: 2023

description: While women form an increasing proportion of the Australian labour market, their experience of work is often reactive and characterised by 'drift'. To counteract this, women are advised by an ever increasing number of researchers, consultants and lay people to engage in long term planning and decision making, in sum, to both think and act strategically. The opportunity to think strategically, however, may not necessarily arise and may not necessarily result in the pursuit of particular strategies. The possibility and opportunity for women to strategise is dependant on their domestic circumstances both in their responsibilities and the degree of dependence. The way in which the two intersect affects the possibility of women actively strategising. A typology of such responses is developed showing that it is only under specific conditions that women will be able to 'strategise'. Under other conditions their responses may by characterised as 'tactising', 'routinising' or 'feminising'. This thesis therefore is specifically interested in the effects of domestic dependancy and responsibility on women's strategising and how this, in turn, affects the range and variety of strategies which they can pursue. In order to explore the proposed link between women's domestic arrangements and strategising, the thesis reports results from a study of a bureaucratic organisation, the Department of Community Services of the Tasmanian Public Service. Recent reforms have made it a friendly work environment for women such that, formally, they have the same opportunities as their male counterparts. However women's opportunity to strategise will be affected by their domestic circumstances. The empirical findings from this study are broadly consistent with the theoretical approach. Women with heavy domestic commitments, find it negatively affects the time and energy available for work in the public sphere, and respond by 'routinising'. By contrast, women relatively free of such responsibilities can devote time and effort to their occupational lives. They are free to engage in a range of 'occupational \strategies\"' in order to be occupationally mobile and to advance their careers."
Irradiation pasteurization of bovine muscle
Creators: name: Mawdsley, Robert Leslie
Publisher: name: University of British Columbia
Year: 2011

description: The effect of pasteurizing dose levels of irradiation on the lipid and protein fractions of raw bovine muscle was studied by chemical amalysis and taste panel evaluation. The following storage conditions were evaluated: (a) Long term anaerobic storage at 39°F (b) Short term aerobic storage at 39°F (c) Frozen storage at -10°F (d) Cooking and short term aerobic storage at 39°F. Free fatty acid content increased with time of storage at 39°F. Irradiation with 1 Mrad of γ irradiation depressed free fatty acid development. During frozen storage the unirradiated sample was significantly higher in free fatty acids than the irradiated samples (0.1 Mrad and 0.5 Mrad). The quantity of phospholipid was reduced by both aerobic and anaerobic storage but no significant difference was evident between irradiated and unirradiated samples. The formation of free amino acids during storage was retarded by irradiation. A significant difference in flavour between control samples and those which received 0.5 Mrad of irradiation was found consistently by taste panel evaluation. The flavour difference resulted from characteristic irradiation odour. Rancid flavours were not detected by the panel. Thiobarbituric reactive substances (TBRS) increased during short term aerobic storage, however a significant difference did not exist between irradiated and unirradiated samples. During long term anaerobic storage the TBRS of irradiated samples increased faster than that of unirradiated samples, but the difference was relatively small. During frozen storage TBRS increased in direct proportion to the level of irradiation. Aerobic storage of cooked meat at 39°F resulted in a rapid increase of TBRS but the level was not affected by irradiation.

description: In order to study an intrinsic chemical potential jump between the hole- and electron-doped high-Tc superconductors, we have performed core-level X-ray photoemission spectroscopy (XPS) measurements of Y0.38La0.62Ba1.74La0.26Cu3Oy (YLBLCO), into which one can dope both holes and electrons with maintaining the same crystal structure. Unlike the case between the hole-doped system La_2-xSrxCuO4 and the electron-doped system Nd_2-xCexCuO4, we have estimated the true chemical potential jump between the hole- and electron-doped YLBLCO to be ~0.8 eV, which is much smaller than the optical gaps of 1.4-1.7 eV reported for the parent insulating compounds. We attribute the reduced jump to the indirect nature of the charge-excitation gap as well as to the polaronic nature of the doped carriers.

description: We discuss the feasibility of negative refraction with reduced absorption in coherently driven atomic media. Coherent coupling of an electric and a magnetic dipole transition by laser fields induces magneto-electric cross-coupling and negative refraction at dipole densities which are considerably smaller than necessary to achieve a negative permeability. At the same time the absorption gets minimized due to destructive quantum interference and the ratio of negative refraction index to absorption becomes orders of magnitude larger than in systems without coherent cross-coupling. The proposed scheme allows for a fine-tuning of the refractive index. We derive a generalized expression for the impedance of a medium with magneto-electric cross coupling and show that impedance matching to vacuum can easily be achieved. Finally we discuss the tensorial properties of the medium response and derive expressions for the dependence of the refractive index on the propagation direction.

description: Unpublished results of S Straus and W Browder state that two notions of homotopy equivalence for manifolds with smooth group actions - isovariant and equivariant - often coincide under a condition called the Gap Hypothesis; the proofs use deep results in geometric topology. This paper analyzes the difference between the two types of maps from a homotopy theoretic viewpoint more generally for degree one maps if the manifolds satisfy the Gap Hypothesis, and it gives a more homotopy theoretic proof of the Straus-Browder result.

Inner and outer weather: Creative practice as contemplative ecological inquiry
Creators: name: Vasko, Zuzana
Publisher: name: PRISM: Casting New Light on Learning, Theory and Practice
Year: 2020

description: Ecological crises exist not only in the external environment; they have their source within us — in the mind and in personal and cultural values (Bai, 2012; Stoknes, 2018). Arts-based and contemplative inquiry are helpful in opening the self and the senses to the natural world and its elemental dynamics of weather. Creative contemplative practice also creates room for inner exploration about how we relate to other species and to the larger cosmos. This article describes a drawing project that was undertaken in an endeavour to build these connections, both within and without. Through the process of walking and making drawings of the bark of trees in a local ecosystem, attention was given also to the dynamics of weather and how we might be more conscious of its role in everyday life, with the belief that such caring attentiveness is necessary in a time of critical climate change. From a perspective that values interconnectivity, this exploration puts forth that the elements of air and water are within us too, and that our inner weather – our shifting psycho spiritual states – is affected by earth’s dynamics, just as, more importantly, and our more long-term values and psycho-spiritual perspectives have significant effects on ecological health.

Investigation of Bovills landslip, near Devonport, Tasmania
Creators: name: Moon, AT
Publisher: name: University Of Tasmania
Year: 2023

description: Bovills Slip occurs in weathered basalt colluvium at the base of a coastal scarp about 2 km east of Devonport on the north coast of Tasmania. The colluvium consists of red-brown fissured silty clay with rock fragments. Many landslips occur in colluvial soils on the coastal scarp and also in basalt-derived soils elsewhere. Thus a detailed investigation and stability analysis of Bovills Slip is relevant to the general slope failure problem in Tasmania. Pore water pressures measured with open standpipe piezometers show a correlation with rainfall, with peak pressures occurring during wet winter months. Effective shear strength parameters were determined by both multi-stage direct shear tests and consolidated undrained triaxial tests with pore pressure measurements. Different residual shearing mechanisms were recognised in the shear box tests. Significantly different values of residual strength were associated with these different mechanisms. The fully softened strength parameters appropriate for the analysis of first-time landslips were investigated by both triaxial and shear box tests. For the soil tested both the residual and fully softened effective friction angles showed a pattern of dependence on the plasticity. Surface movements have been monitored by repeated surveys, and subsurface movements have been monitored by regularly checking piezometer tubes for deformation. After heavy rain, in August 1981, the landslip moved by 20 to 30 mm. A two dimensional model of the August 1981 failure has been analysed by limit equilibrium methods. The factor of safety is most sensitive to variations in piezometric head and cohesion. Analysis has been used to assess the relative change in factor of safety (stability) caused by changes in the slope and by remedial measures. The stability was reduced when the slope was undercut by roadworks in 1973, and the first movements caused a decrease in shear strength of the soil. Downslope movements have produced shape changes which have tended to increase the factor of safety. Toe drainage, toe surcharge, 'and re-grading have already resulted in increased stability. Subsurface drainage, although effective, would be relatively expensive. Lime stabilisation and tree planting were also considered. In the long term well established trees may increase the factor of safety by as much as 50%. Possible future research on landslips in Tasmania is discussed in order to demonstrate how the results of this detailed investigation may be used as a starting point for regional studies.

description: Pb films embedded with homogeneously distributed cobalt (Co) nanoparticles (mean size 4.5 nm) have been prepared. Previous transport investigations have shown that Co particles induce spontaneous vortices below the superconducting transition temperature (T$_{c}$) in zero external magnetic field. In this paper we study in detail the influence of the Co volume franction and an external magnetic field on the superconducting transition in such composites. The large difference in T$_c$-reduction between the as-prepared and annealed samples can be attributed to the different superconducting coherence lengths and the resulting different diameters of the spontaneous vortices in these samples.

Modelling pseudomonad growth in milk and milk-based products
Creators: name: Neumeyer, K
Publisher: name: University Of Tasmania
Year: 2023

description: Predictive microbiology is a method by which the growth responses of microorganisms of concern are modelled mathematically in respect of the major factors affecting growth. A model for the growth of Pseudomonas (the main organism of concern in refrigerated milk and some milk products) was developed and validated. Psychrotrophic psuedomonads were isolated from various modified and whole milks, using both Victorian (obtained from CSIRO Dairy Research Laboratories) and Tasmanian milks. Growth rates in artificial broth media were determined using turbidimetric methods. By fitting a sigmoidal curve (using the Gompertz function) to the data, generation times can be calculated and growth rates (by turbidimetric or viable count methods) determined. All strains were grown in artificial broth media at 10¬¨‚àûC and growth rates compared. The fastest growing strain (Pseudomonas putida 1442) was used to develop the model i.e., a worst case approach was adopted. A square root model (Ratkowsky et al, 1982) was developed for P.putida 1442 in artificial broth media by determining the generation time at 0.5¬¨‚àûC intervals from 0 to 50 ¬¨‚àûC. A similar procedure was used to model the effect of water activity (using sodium chloride as the solute) on Pseudomonas spp. Generation times calculated by turbidimetric and viable counts were found to differ. This difference was found to be constant with respect to temperature and was incorporated into the modelling process so that all models expressed generation times equivalent to those calculated by viable counts, the standard method for enumerating microorganisms in food products. A literature search comparing the notional minimum temperature (T min) for growth of psychrotrophic pseudomonads found that the Tmin was the same (265.4K ¬¨¬± 0.7) despite the source of the organism. This implies that only one model for temperature dependence is needed for psychrotrophicPseudomonas in dairy, meat and poultry products. The model was validated both in the laboratory and in industry using various milk and milk based products. The validation process involved monitoring the growth of pseudomonads at various temperatures and comparing the observed generation times to those predicted using bias and accuracy factors (Ross, 1993). The temperature model has been incorporated into prototype computer software and trialled in the dairy industry. The validation process showed the psychrotrophic pseudmonad model to accurately predict the growth of pseudomonads in the products tested. In some instances in industry, further information in the form of the duration of lag phase, is required to maximise the accuracy of the model. The capacity to input this information was included in the prototype software.

description: V440 Per is a Population I Cepheid with the period of 7.57 day and low amplitude, almost sinusoidal light and radial velocity curves. With no reliable data on the 1st harmonic, its pulsation mode identification remained controversial. We obtained a radial velocity curve of V440 Per with our new high precision and high throughput Poznan Spectroscopic Telescope. Our data reach the accuracy of 130 m/s per individual measurement and yield a secure detection of the 1st harmonic with the amplitude of A_2= 140+/- 15 m/s. The velocity Fourier phase ϕ_21 of V440 Per is inconsistent at the 7.25 σlevel with those of the fundamental mode Cepheids, implying that the star must be an overtone Cepheid, as originally proposed by Kienzle et al.(1999). Thus, V440 Per becomes the longest period Cepheid with the securely established overtone pulsations. We show, that the convective nonlinear pulsation hydrocode can reproduce the Fourier parameters of V440 Per very well. Requirement to match the observed properties of V440 Per constrains free parameters of the dynamical convection model used in the pulsation calculations, in particular the radiative losses parameter.

description: The ability to parasitize living hosts as well as decompose dead organic matter is both common and widespread across prokaryotic and eukaryotic taxa. These parasitic decomposers have long been considered merely accidental or facultative parasites. However, this is often untrue: in many cases, parasitism is integral to the ecology and evolution of these organisms. Combining life cycle information from the literature with a generalized eco-evolutionary model, we define four distinct life history strategies followed by parasitic decomposers. Each strategy has a unique fitness expression, life cycle, ecological context, and set of evolutionary constraints. Correctly classifying parasitic decomposers is essential for understanding their ecology and epidemiology and directly impacts efforts to manage important medical and agricultural pathogens.
Cache performance in multithreaded processor architectures

description: Multithreading techniques used within computer processors aim to provide the computer system with a means to tolerate long latency operations and also dynamically convert variable software concurrency into the maximum parallelism in hardware. To meet this challenge resources must be allocated to threads. Cache in the memory hierarchy poses a problem because it is not an allocated resource. The effect of interference in the cache between coactive threads because of this can lead to poor performance results compared to the same threads executing without interference on similar hardware. The memory cache poses a resource management problem in a multithreaded architecture because it does not distinguish between accesses from different threads and thus is transparent to the memory model. Short lived or intermittent threads can displace the cache lines still in active use by other threads. This interference in the cache voids the benefit of the cache to those other threads on the subsequent access to a displaced active cache line. Techniques to reduce this interference will increase the performance achieved from multithreaded hardware. We propose analytical models for the instantaneous miss rate of the cache that enable the interference between threads to be determined. The interference between threads is determined dependent on their dynamic interaction. Inputs to the models are the cache design parameters and the memory behaviour of each thread. Sharing, latency effects, cache design, and memory usage are investigated with the models. A type of miss, the latency miss, is investigated. This category of miss has not been described previously and occurs between threads with shared memory in non-blocking multithreaded architectures. A proposal is also made for an approach called thread pulling which is a scheduling scheme aimed at reducing interference by increasing the locality of reference of concurrent threads. New methods were determined that produce mathematically tractable measurements of memory behaviour for the analytical cache miss rate models. The dependence on arbitrary factors used while making the measurements was minimised via these methods. Using these, the calculation of the working set of a thread at an instant without requiring an arbitrary choice of the working set parameter is developed. Two cache miss models are proposed, validated, and used to analyse the performance of the cache under a range of multithreaded loads. First, a single threaded analytical cache miss model at a point in time. Second, a multithreaded analytical cache miss rate model using the working sets of the active threads at a point in time. Significant agreement was found between the predictions of the models and measurements of the real cache performance. Our analytical cache miss rate models provide insight to computer architects and compiler writers toward performance related optimisations.

description: The structural profiles and electronic properties of pentacene (C$_{22}$H$_{14}$) multilayers on Ag(111) surface has been studied within the density functional theory (DFT) framework. We have performed first-principle total energy calculations based on the projector augmented wave (PAW) method to investigate the initial growth patterns of pentacene (Pn) on Ag(111) surface. In its bulk phase, pentacene crystallizes with a triclinic symmetry while a thin film phase having an orthorhombic unit cell is energetically less favorable by 0.12 eV/cell. Pentacene prefers to stay planar on Ag(111) surface and aligns perfectly along silver rows without any molecular deformation at a height of 3.9 Å. At one monolayer (ML) coverage the separation between the molecular layer and the surface plane extends to 4.1 Å due to intermolecular interactions weakening surface--pentacene attraction. While the first ML remains flat, the molecules on a second full pentacene layer deposited on the surface rearrange so that they become skewed with respect to each other. This adsorption mode is energetically more preferable than the one for which the molecules form a flat pentacene layer by an energy difference similar to that obtained for bulk and thin film phases. Moreover, as new layers added, pentacenes assemble to maintain this tilting for 3 and 4 ML similar to its bulk phase while the contact layer always remains planar. Therefore, our calculations indicate bulk-like initial stages for the growth pattern.

description: We evaluate the mixed partition function for dyonic BPS black holes using the recently proposed degeneracy formula for the STU model. The result factorizes into the OSV mixed partition function times a proportionality factor. The latter is in agreement with the measure factor that was recently conjectured for a class of N=2 black holes that contains the STU model.

Social role valorization and supported employment : their application in the institutional setting and effects on the development in adaptive behaviour of people with moderate to severe intellectual disability
Creators: name: McVilly, KR
Publisher: name: University Of Tasmania
Year: 2023

description: Intellectual disability is discussed in terms of both characteristics inherent in the individual and a state determined by the interaction of the individual with their environment. Criticisms of psychometric and etiological categorisation are given. It is proposed that the process of habilitation be best served by a focus on the development of the person's skills of adaptive behaviour. Furthermore, the principles of Social Role Valorization (S.R.V.) as they are applied to the development of supported employment options are proposed as a means of remediating the effects of intellectual disability, by fostering the development of adaptive skills. It is argued that the principles of S.R.V. can be effectively applied in the development of institutional services as well as in community-based settings, and that they are applicable to the development of services for people with even severe degrees of intellectual disability.
Studies on the antigenic properties of ferredoxin from Clostridium pasteurianum

description: It was established that antibodies could be evoked in rabbits against ferredoxin purified from cultures of Clostridium pasteurianum and against its performic acid oxidized derivative. The extent of cross-reaction was studied between the two antisera and four related antigens: native ferredoxin, iron-sulfide free ferredoxin, performic acid oxidized ferredoxin, arid S-carboxymethylated ferredoxin. All combinations demonstrated cross reactivity by complement fixation, and in the case of oxidized ferredoxin antiserum, three preparations, native ferredoxin, iron sulfide free ferredoxin, and performic acid oxidized ferredoxin precipitated antibody. The data obtained with these cross-reactivity studies Indicated that the cysteine-containing regions of the ferredoxin molecule were not critically involved as antigenic determinants. The C-terminal region of the protein was considered for further study. This octapeptide was synthesized and tested for its ability to combine with antibody directed against both native ferredoxin and its performic acid oxidized derivative. The peptide exhibited specific binding to both antisera as demonstrated by inhibition of complement fixation and precipitation, and by equilibrium dialysis experiments. It is suggested that C. pasteurianum ferredoxin is antigenic in rabbits, that cysteine residues are not involved in at least two of the antigenic regions of the protein, and that the C-terminal octapeptide is one of the antigenic determinants of this molecule.

description: Starting from the action of two coincident non-BPS D9-branes, we investigate kink configurations of the U(2) matrix tachyon field. We consider both Str and Tr prescriptions for the trace over gauge indices of the non-BPS action. Non-abelian tachyon condensation in the theory with Tr prescription, and the resulting fluctuations about the kink profile, are shown to give rise to a theory of two coincident BPS D8-branes. This is a natural non-abelian generalization of Sen's mechanism of tachyon condensation on a single non-BPS Dp-brane yielding a single BPS brane of codimesion one. By contrast, starting with the Str gauge trace prescription of the coincident non-BPS D9-brane action, such a generalization of Sen's mechanism appears problematic.

A radical act of remembering

description: Anatomy is a self depiction, a series of body images in the manner of self portraits, created without recourse to a mirror image. The work comprises largescale coloured etchings, which are assemblages of body prints and collaged 'found' anatomical drawings. The symbolism refers to the pre-Oedipal relation. This issue is met in Julia Kristeva's discussion of the semiotic chora, Luce Irigaray's discussion of Merleau-Ponty's analysis of vision, and other sources that I have referred to which reconsider the Lacanian narrative in psychoanalysis. Much of the debate about women's place in the symbolic realm has been conducted at the level of language. Anatomy contributes a visual parallel: a move to subvert the symbolic centrality of the female body as a passive plane or surface upon which meanings are projected, and to reconfigure a body image which acts as an active signifying entity. The pictorial solution that I arrived at utilises back-lighting to activate the body images, adding a visceral, immediate, and deliberately auratic element to the etched images. The illumination notionally returns the viewer's gaze and creates an intimacy - something like a caress - which alludes to the pre-Oedipal maternal gaze.
