True fictions : an investigation of identity, narrative, and photography
Creators: name: Psotova, H
Publisher: name: University Of Tasmania
Year: 2023

description: This research project explores the narrative potential of the photographic medium, and the ways in which photography translates reality and fiction. As an aesthetic object, a photograph is an iconographic form not unlike an open-ended story, which in its dualism incites the viewer's imagination and curiosity. I have intended to test the complex translations of reality and truth within the photographic image. Taking into consideration the continuum of photography's history, the work of the artists who have explored the terrain of constructed photography, and in a visual and/or conceptual way inspired my project, and my personal desire to explore the duplicate truth of photography, I have tried to find new ways to visually reconfigure the aspect of truth within fiction. Additionally, I have sought a new approach to the issues of identity using the self-portrait technique and the theatrical practice of transformation and role-playing. Combining documentary and staged self-portrait techniques, my aim was to produce an imagery, which presents the viewers with an open-ended narrative where fantasies and deceptions blend. I have employed photography's mechanical and semi-objective nature to produce a realistic representation of the construct. Relying on photography's ability to generate believable fictions, I have chosen to participate in my images as a pretended character. I have set my performance against the real life street milieu, and blended the pretence directly with the element of chance, hoping to emulate the immediate reality with the utmost veracity. As a result, the images contain both the naturalness of a documentary photograph and the theatricality of the construct. They suggest the 'real', but their effect is, essentially, always tentative and ambiguous. The intent of the imagery is to extend the interpretation and symbolic potential of a photographic narrative, and to encourage the viewer to search beyond the obvious. Through the fluid mix of reality and fiction my imagery invokes the proximity of truth and deceptiveness, encouraging the viewers to enter into a dialogue on the identity subsumed in the instantaneous reality of the street. Represented in the straightforward manner of street photography, the images are stimuli and evocations, reflecting on the discourse between the real and imaginary, the personal 'truth' and intended deceptiveness.

description: We propose a general method to circumvent the singularity of arbitrary 2D cloaks, which arises from infinitely large values of material parameters at inner boundaries. The presented method is based on the deformation view of the transformation design method. It is shown that by adjusting the principle stretch out of the cloaking plane, 2D cloaks of arbitrary shapes without singularity can be constructed. It is also demonstrated that the method based on the equivalent dispersion relation and the design method for nonsingular 2D cloak from mirror-symmetric cross section of 3D cloak can be derived from the proposed theory. Examples of a cylindrical electromagnetic cloak and an arbitrary shaped 2D electromagnetic cloak without singularity are provided to illustrate the method.

description: We present an analysis of magnetic traps for ultracold atoms based on current-carrying wires with sub-micron dimensions. We analyze the physical limitations of these conducting wires, as well as how such miniaturized magnetic traps are affected by the nearby surface due to tunneling to the surface, surface thermal noise, electron scattering within the wire, and the Casimir-Polder force. We show that wires with cross sections as small as a few tens of nanometers should enable robust operating conditions for coherent atom optics (e.g. tunneling barriers for interferometry). In particular, trap sizes on the order of the deBroglie wavelength become accessible, based solely on static magnetic fields, thereby bringing the atomchip a step closer to fulfilling its promise of a compact device for complex and accurate quantum optics with ultracold atoms.

John Collier and the Protestant churches
Creators: name: Stacey, Susan Carol LeCompte
Publisher: name: University of British Columbia
Year: 2010

description: In 1933 President Franklin Roosevelt appointed John Collier to the post of United States Indian Commissioner. Collier had been a social worker in New York City and California during the early twentieth century, but the effects of the industrial mode of life that he constantly witnessed made him extremely pessimistic about the ability of the modern world to foster and sustain any type of healthy social system. In the early 1920's he was the guest of the Taos Pueblos Indian tribe for several months, and during his stay with these native Americans he was deeply impressed by their genius at maintaining, in the face of nearly overwhelming pressure, a culture whose primary function was the creation and sustenance of well-balanced individual and group personalities. Throughout the 1920's: he incessantly battled against any legislation, executive order, or social or economic pressure that was endangering what he saw to be one of the last truly humane civilizations on earth. When he became Commissioner, he instituted a program designed to revive the tribal structures, their power and status systems, their languages, their religions, and all other vital aspects of their existence. He backed this up with a comprehensive plan for economic, educational, and health improvement so that the natives would be able to solidly entrench themselves in the type of life they desired. One group who opposed this policy of Collier's were the Protestant missionaries who labored among the aborigines. From the earliest days of their missions they had set themselves to the task of "civilizing" the Indian and helping him to assimilate into the larger American society where he could more easily and more effectively function as a Christian. They were therefore dismayed by Collier's attempt to promote segregation, isolation, and a return to the original lifestyles, although they did come to approve of the other aspects of his work. This thesis examines Collier's philosophy and program of Indian administration through his own writings and through executive reports, explores the depth and importance of their Indian missions to the Protestant churches, and then sets forth and analyzes the negative Protestant reaction to Collier's Commissionership. It attempts to explore the nature of a confrontation between two powerful forces in American life. The general conclusion that emerges from this work is that Collier's appointment marks the first real break in the cooperation of church and state in Indian affairs. Collier began a secularization of the office that has continued to the present day. The missionaries recognized the implication of this secularization for their own future and responded accordingly. Both-sides had rallied around ideological standards (the church was committed to its theology, Collier to his sociological beliefs) and neither could nor would give way. Thus the missionaries tended to work themselves out of a major role in the management of Indian affairs.

Computer simulation and investigation of underwater two-part and multi tow systems
Creators: name: Ranmuthugala, Susantha
Publisher: name: University Of Tasmania
Year: 2023

description: To maximise effectiveness, towed underwater sonar bodies generally require perturbations from the steady state motion to be minimised. The instantaneous position of the towed body is influenced by the unsteady, wave-induced motion of the surface vessel, transmitted via the tow cable. This can render the trajectory of the underwater body beyond acceptable limits for sonar operations. In an effort to decouple this motion, a two-part tow configuration has been employed. This thesis describes a three-dimensional dynamic computer model developed to investigate two-part tows by modelling the individual cables separately and coupling them dynamically. This approach also enables the modelling of series and parallel multiple tow configurations. The cable system, modelled using a three degree-of freedom finite difference approach, is then coupled to the six degree-of-freedom underwater towed bodies at the appropriate locations of the cable system. The modelling of the cable as a continuous medium and the derivation of the stress wave speeds are also presented, followed by the validity and.effects of representing it as a discretised model. The solution to the dynamic equations describing the motion of the discretised tow configuration is carried out using an implicit multi-step numerical technique, subject to specific boundary conditions. This allows the values to be improved through an iterative procedure, until sufficient convergence is achieved. An introduction into the use of such numerical techniques in engineering and an analysis of the numerical procedure used in the solution are also presented. The requirements for accuracy and numerical stability of the integration technique are investigated and a guide to the time interval for the time stepping algorithm is deduced. The computer model is successfully validated using experimental results from scaled model tests in a circulating water channel. These results together with those obtained from full scale sonar trials utilising small coastal craft are used to further investigate the behaviour of the two-part tow configuration to varying parameters. The experimental results and the computer model enables the user to identify the optimum tow configuration for the prevailing conditions. The thesis also presents a detailed review of the various methods available to investigate underwater cables and vehicles, together with prediction methods for their hydrodynamic coefficients. The latter coefficients for the scaled models used in the project are obtained via experimental procedures. Although a number of investigations have been carried out dealing with aspects of underwater towing operations, the strength of this investigation lies in that it combines these aspects, i. e. mathematical modelling, computer simulation, prediction of the hydrodynamic coefficients, scaled model experiments, full scale trials, and the analysis of the numerical technique, into one study.

description: By comparing the Q-values for the 46Ti(3He,t)46V and 47Ti(3He,t)47}V reactions to the isobaric analog states the Q-value for the superallowed Fermi-decay of 46V has been determined as Q_{EC}(46V)=(7052.11+/-0.27) keV. The result is compatible with the values from two recent direct mass measurements but is at variance with the previously most precise reaction Q-value. As additional input quantity we have determined the neutron separation energy S_n(47Ti)=(8880.51+/-0.25) keV.

description: We investigate a peculiar feature at the hottest, blue end of the horizontal branch of Galactic globular cluster omega Centauri, using the high-precision and nearly complete catalog that has been constructed from a survey taken with the ACS on board the HST, that covers the inner 10x10 arcminutes. It is a densely populated clump of stars with an almost vertical structure in the F435W-(F435W-F625W) plane, that we termed "blue clump". A comparison with theoretical models leads to the conclusion that this feature must necessarily harbor either hot flasher stars, or canonical He-rich stars --progeny of the blue Main Sequence sub population observed in this cluster-- or a mixture of both types, plus possibly a component from the normal-He population hosted by the cluster. A strong constraint coming from theory is that the mass of the objects in the "blue clump" has to be very finely tuned, with a spread of at most only $\sim$0.03Mo. By comparing observed and theoretical star counts along both the H- and He-burning stages we then find that at least 15% of the expected He-rich Horizontal Branch stars are missing from the color-magnitude diagram. This missing population could be the progeny of red giants that failed to ignite central He-burning and have produced He-core White Dwarfs. Our conclusion supports the scenario recently suggested by Calamida et al. (2008) for explaining the observed ratio of White Dwarfs to Main Sequence stars in omega Centauri.

description: We show that inverse problems with a truncated quadratic regularization are NP-hard in general to solve, or even approximate up to an additive error. This stands in contrast to the case corresponding to a finite-dimensional approximation to the Mumford-Shah functional, where the operator involved is the identity and for which polynomial-time solutions are known. Consequently, we confirm the infeasibility of any natural extension of the Mumford-Shah functional to general inverse problems. A connection between truncated quadratic minimization and sparsity-constrained minimization is also discussed.

A fast-track ship simulation model for port studies
Creators: name: Reynolds, E. J.
Publisher: name: University Of Tasmania
Year: 2023

description: Port studies are systematic investigations of the safety, or difficulty, of manoeuvring ships in a port in various environmental conditions. They are often used to enable decision-makers to analyse alternate port layouts for a proposed new port, or to assess the safety of manoeuvring a particular ship in an existing port. Port studies are generally carried out in ship manoeuvring simulators, in real time, using real pilots. These studies can be extremely time consuming and costly, as a port study requires a large number of simulations covering a range of weather conditions and ships. Although a computer can perform these simulations much faster than real time, a human pilot cannot. In order to reduce the numbers of scenarios which must be investigated in a full mission bridge simulator, it is proposed to develop a 'fast-track' method of rating the difficulty of simulation scenarios, using a simple computer search algorithm in place of a human pilot. As the first step in developing this search method, a simple model, capable of manipulating the rudder and engine only, has been created. Using the Australian Maritime Engineering Co-operative Research Centre's existing PC-based ship handling simulator, this computer search algorithm replaces the supervisory role of a human pilot in a simulation, and uses rudder and engine commands to search all possible routes from a start point to a given target point. The computer search method logs the numbers of successful and unsuccessful paths tested in this process. Two simple computer search models were created and used to evaluate the difficulty of a number of port exercises, and each of these port exercises was also evaluated in the Australian Maritime College's full-bridge simulator, using experienced master mariners. These mariners rated the difficulty of each port exercise on a preset scale, for comparison with the results of the computer assessments of difficulty. This thesis presents the models for the computer search algorithms, and the results of two series of tests using a 215m bulk carrier. The final set of tests shows good agreement between the assessments of difficulty given by the master mariners, and the assessments produced by the one of computer search methods. The other computer search method proved to be impractical to implement.
Evidence of an initially magnetically dominated outflow in GRB 080916C

description: The composition of gamma-ray burst (GRB) ejecta is still a mystery. The standard model invokes an initially hot ``fireball'' composed of baryonic matter. Here we analyze the broad band spectra of GRB 080916C detected by the Fermi satellite. The featureless Band-spectrum of all five epochs as well as the detections of >~10 GeV photons in this burst place a strong constraint on the prompt emission radius, which is typically >~ 10^{15} cm, independent on the details of the emission process. The lack of detection of a thermal component as predicted by the baryonic models strongly suggests that a significant fraction of the outflow energy is initially not in the ``fireball'' form, but is likely in a Poynting flux entrained with the baryonic matter. The ratio between the Poynting and baryonic fluxes is at least ~(15-20) at the photosphere radius, if the Poynting flux is not directly converted to kinetic energy below the photosphere.

description: The aim of this paper is to evaluate changes in the role of agribusiness in the Polish economy, the relationships between various spheres of agribusiness and its links with othersectors of the national economy. The research was conducted on the basis of the input-output tables for 2005, 2010, and 2015 published by Statistics Poland. The analysis also confirmed most of the relationships formulated so far between the agribusiness development path and the level of economic development of a given country. From 2005-2015, the share of agri-business in creating the gross value added of the Polish economy decreased, similarly as the role of internal turnover in the material supply of agriculture, while the food sector became the leading link in the agri-food sector. The agri-business sector also showed strong links with the other sectors of the economy. The changes in the food economy were caused by the intensified relations of this sector with the other countries, which translated into benefits from the international division of labor.

The effect of spatial layout and social similarity on urban neighbouring
Creators: name: Treasurywala, Mary-Rose
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents a detailed study of the effect of functional distance and social similarity on the greetings and visits between contiguous neighbours. Functional distance is predicted to have an inverse relation with greetings while social similarity is predicted to have a direct relation with visiting between contiguous neighbours. In accordance with previous researchers, functional distance is predicted to have an inverse relation with visiting only for socially similar, but not for socially dissimilar, neighbours. Women, whose single family houses are located throughout metropolitan Vancouver, were interviewed in the summer months. Similarity in six characteristics, which were employed separately, in specific combinations, and all together, was determined for each respondent-contiguous neighbour pair. This pair was the unit of analysis. Somers' d was used to test the direction and strength of the relationships. A calculation of Goodman and Kruskal's gamma substantiated the deductions which were based on Somers' d values. It was found that these contiguous neighbours tend not to have any form of contact with each other. The functional distance between neighbour pairs was found, as predicted, to be consistently negatively related to greetings while their similarity was consistently positively related to visiting. Functional distance was negatively, and more strongly, related to casual visiting for similar rather than dissimilar pairs, but the strength of its association with planned visiting was the same regardless of similarity. Some limitations of this research are outlined with suggestions for improvements in future endeavours in this area.

description: As the application of generative adversarial networks (GANs) expands, it becomes increasingly critical to develop a unified approach that improves performance across various generative tasks. One effective strategy that applies to any machine learning task is identifying harmful instances, whose removal improves the performance. While previous studies have successfully estimated these harmful training instances in supervised settings, their approaches are not easily applicable to GANs. The challenge lies in two requirements of the previous approaches that do not apply to GANs. First, previous approaches require that the absence of a training instance directly affects the parameters. However, in the training for GANs, the instances do not directly affect the generator's parameters since they are only fed into the discriminator. Second, previous approaches assume that the change in loss directly quantifies the harmfulness of the instance to a model's performance, while common types of GAN losses do not always reflect the generative performance. To overcome the first challenge, we propose influence estimation methods that use the Jacobian of the generator's gradient with respect to the discriminator's parameters (and vice versa). Such a Jacobian represents the indirect effect between two models: how removing an instance from the discriminator's training changes the generator's parameters. Second, we propose an instance evaluation scheme that measures the harmfulness of each training instance based on how a GAN evaluation metric (e.g., Inception score) is expected to change by the instance's removal. Furthermore, we demonstrate that removing the identified harmful instances significantly improves the generative performance on various GAN evaluation metrics.

description: In this paper, we propose a scheme, called the "algebraic watchdog" for wireless network coding, in which nodes can detect malicious behaviors probabilistically, police their downstream neighbors locally using overheard messages, and, thus, provide a secure global "self-checking network". Unlike traditional Byzantine detection protocols which are receiver-based, this protocol gives the senders an active role in checking the node downstream. This work is inspired by Marti et. al.'s watchdog-pathrater, which attempts to detect and mitigate the effects of routing misbehavior. As the first building block of a such system, we focus on a two-hop network. We present a graphical model to understand the inference process nodes execute to police their downstream neighbors; as well as to compute, analyze, and approximate the probabilities of misdetection and false detection. In addition, we present an algebraic analysis of the performance using an hypothesis testing framework, that provides exact formulae for probabilities of false detection and misdetection.

description: The purpose of the research is to evaluate the socio-economic consequences of increasing the area of agricultural land under organic farming in Poland. Increasing the share of organic farms in agricultural land could lead to a reduced agricultural production, which would pose a threat to food security. Implementing the principles of an integrated and precise production system of a greater range comparing to organic farming could be a competitive solution that would contribute to achieving the environmental and climate protection objectives to a greater extent, while maintaining the existing production rate. The implementation of the objectives was based on a comparative method: the authors compareorganic farms in Poland and Germany with farms applying conventional agricultural production systems. The research results demonstrate that implementing the Green Deal assumptions related to reaching 25% of agricultural land under organic farming in Poland, while maintaining the existing trends, will lead to a drop in agricultural production by approximately 11%. A competitive solution is to allocate the CAP funds to support pro-environmental measures and programs in the case of all farms. Participation in such programs should be voluntary.

description: It is known that every homeomorphism of the plane has a fixed point in a non-separating, invariant subcontinuum. Easy examples show that a branched covering map of the plane can be periodic point free. In this paper we show that any branched covering map of the plane of degree with absolute value at most two, which has an invariant, non-separating continuum $Y$, either has a fixed point in $Y$, or $Y$ contains a \emph{minimal (by inclusion among invariant continua), fully invariant, non-separating} subcontinuum $X$. In the latter case, $f$ has to be of degree -2 and $X$ has exactly three fixed prime ends, one corresponding to an \emph{outchannel} and the other two to \emph{inchannels}.

Environmental and cultural factors influencing pollination and fruit set in commercial crops of fennel (Foeniculum vulgare Mill.)
Creators: name: Falzari, LM
Publisher: name: University Of Tasmania
Year: 2023

description: Foeniculum vulgare Mill., (fennel), is grown commercially in Tasmania as an essential oil crop. Although oil is produced throughout the plant, approximately 95% is located in the fruits and fruit set directly influences oil yield. In Tasmania commercially grown fennel frequently has a percentage fruit set less than 50%. Research was undertaken into factors influencing fruit set, with the objective of improving fruit set, oil yield and economic returns to growers. The project began with an examination of flower morphology and physiology. Particular importance was placed on the fact that fennel is protandrous and therefore self-incompatible through the timing of pollen production and stigma receptivity. A field trial demonstrated that at high planting densities, fennel produces fewer higher order umbels. This reduces the time span of pollen production and reduces the quantity of pollen available for pollination of the flowers developing later in the season. The work incorporated a study of pollen viability and appeared to show that although pollen viability of glasshouse grown plants is often poor, the problem is not carried over into the field. A field trial involving the application of exogenous hormone gave rise to the hypothesis that competition within the fennel canopy causes poor fruit set. This competition could be for a number of growth factors including nutrients or carbon dioxide. The two factors studied in more detail were light intensity and water stress. Trials suggested fennel to be an obligate heliophyte. It has an open canopy as an adaptation to avoid the absorption of light in excess of that which can be utilised in photosynthesis. In the Tasmanian environment this feature is beneficial in allowing penetration of light through the canopy and prevents shading of the lower umbels. However, it makes fennel inefficient with respect to light absorption and thus possibly makes light a limiting factor. Initial experiments on the effect of water stress in fennel showed the stomata to react slowly to decreasing water availability. They remained open despite the plant wilting. Further investigation showed fennel to have a root system capable of tapping water at depth. Fennel is thought to be a phreatophyte. Fennel plants showed the ability to adjust to cycles of decreasing water potential and after a few cycles of water stress, they no longer wilted. Attempts were made to test the theory ttiat the plant adapted to water stress by increasing its osmotic potential but the methods used were inconclusive.

description: A direct Biot-Savart integration is used to decompose the strain rate into its local and nonlocal constituents, allowing the vorticity alignment with the local and nonlocal strain rate eigenvectors to be investigated. These strain rate tensor constituents are evaluated in a turbulent flow using data from highly-resolved direct numerical simulations. While the vorticity aligns preferentially with the intermediate eigenvector of the \textit{combined} strain rate, as has been observed previously, the present results for the first time clearly show that the vorticity aligns with the most extensional eigenvector of the \textit{nonlocal} strain rate. This in turn reveals a significant linear contribution to the vortex stretching dynamics in turbulent flows.

description: Number of Distinct Values (NDV) estimation of a multiset/column is a basis for many data management tasks, especially within databases. Despite decades of research, most existing methods require either a significant amount of samples through uniform random sampling or access to the entire column to produce estimates, leading to substantial data access costs and potentially ineffective estimations in scenarios with limited data access. In this paper, we propose leveraging semantic information, i.e., schema, to address these challenges. The schema contains rich semantic information that can benefit the NDV estimation. To this end, we propose PLM4NDV, a learned method incorporating Pre-trained Language Models (PLMs) to extract semantic schema information for NDV estimation. Specifically, PLM4NDV leverages the semantics of the target column and the corresponding table to gain a comprehensive understanding of the column's meaning. By using the semantics, PLM4NDV reduces data access costs, provides accurate NDV estimation, and can even operate effectively without any data access. Extensive experiments on a large-scale real-world dataset demonstrate the superiority of PLM4NDV over baseline methods. Our code is available at https://github.com/bytedance/plm4ndv.

Graduate nursing performance : a descriptive study of the perceptions of graduates, preceptors and clinical nurse consultants in Tasmania
Creators: name: Roberts, Karen Elizabeth
Publisher: name: University Of Tasmania
Year: 2023

description: This descriptive study used the Australian Nursing Council Incorporated (ANCI) Competencies eighteen major headings as a set of performance criteria to investigate four aspects of graduate nursing performance: ‚Äö the perceptions of registered nurses (RN) (Graduates, Preceptors and Clinical Nurse Consultants (CNC)) regarding the expected level of graduate nursing performance at the completion of a Bachelor of Nursing (BN) course, and the commencement of employment as a registered nurse; ‚Äö the perceptions of registered nurses of the actual level of graduate nursing performance near the completion of the first professional year; ‚Äö the components of nursing practice registered nurses believed were critical to a satisfactory level of graduate nursing performance; and ‚Äö the attributes of a Graduate: pe:rc.f':ivf':ci hy registered nurses to represent outstanding nursing performance. All Graduates from the University of Tasmania's BN 1996 programme, RN Preceptors who worked with the Graduates, and the CNC's of the areas where Graduates were employed were invited to participate in the study. Findings revealed that Graduates expected to be functioning at a higher level of performance at the beginning of their graduate year than did the Preceptors and CNCs. There was little agreement between the three groups. When agreement between pairs of groups was examined Preceptors and CNCs agreed the most, followed by Graduates and Preceptors and Graduates and CNCs. When perceptions were sought regarding Graduates' nursing performance near the end of their graduate year Graduates again rated their nursing performance higher than Preceptors and CNCs. There was little agreement between the three groups. When agreement between pairs of groups was examined Graduates and Preceptors agreed the most. Overall, the Graduate and Preceptor groups were more consistent than the CNC group in their rating of Graduate performance. All three groups identified eight performance criteria that were seen as important to achieving a satisfactory nursing performance. These critical Competencies could be interpreted as a beginning description by RNs of their beliefs about \good nursing practice\" and a \"good nurse\". For the Graduate group \"safe practice\" and \"personal/professional continuing education\" were the most frequently cited attributes of outstanding Graduate performance. For the Preceptor and CNC groups the most frequently cited attributes were \"communication skills\" and \"knowledgeable and skillful caregiving\". The findings of the study would suggest that the Preceptors and CNCs most immediately involved in the transition experiences of Graduates need to discuss and share expectations and perceptions of graduate nursing performance between themselves and with the Graduates."

description: In this paper, we demonstrate a source of photon pairs based on four-wave-mixing in photonic crystal fibres. Careful engineering of the phase matching conditions in the fibres enables us to create photon pairs at 597 nm and 860 nm in an intrinsically factorable state showing no spectral correlations. This allows for heralding one photon in a pure state and hence renders narrow band filtering obsolete. The source is narrow band, bright and achieves an overall detection efficiency of up to 21% per photon. For the first time, a Hong-Ou-Mandel interference with unfiltered photons from separate fibre sources is presented.

Proteomic analysis of breast cancer

description: Introduction: Breast cancer is a disease that will affect every woman in her life. Whether that affect will be direct or indirect is, at this stage almost impossible to determine. There have been several key findings in recent years with genes being found that are linked directly to breast cancer. With these being attributed to less than 10% of breast cancers diagnosed, the need for new biomarkers of breast cancer exists. This study aims to find new biomarkers though differential analysis of breast cancer tissue. Several different analysis have been conducted to provide insight in to potential new markers for diagnosing early onset breast cancers, looking for signs in otherwise healthy tissue and ascertaining differences between cancer and healthy tissue as a whole. This study also looks in to the functional areas of proteomic research, determining a need for further investigation in to IGF-1 and ~-casein, which have been inconclusively linked to breast cancer in the past. Methods: By employing selected proteomic technologies including iso-electric focusing and polyacrylamide gel electrophoresis and combining samples from populations from different locations across the globe, collections of two-dimensional gels from breast tissue were differentially compared to isolate proteins that have a high likelihood of being involved in breast cancer. Results: This approach to breast cancer research has led to many proteins being isolated that have a role in breast cancer. The proteins found have a diverse range of roles from signaling proteins to structural proteins. Within those proteins successfully identified are proteins like HSP60, known to have a role in breast cancer, serum albumin which has limited information regarding a role in breast cancer and FLJ20309, one of several proteins that have been assumed from cDNA clones with little available information available regarding its function. Conclusions: This study has led to the discovery of proteins that were previously thought to have limited, if no input in breast cancer. All of the proteins found require further experiments to fully elucidate their function in breast cancer however at least some of these are show promise as being of diagnostic and/or therapeutic value.
Temperature dependence of the exchange splitting in ferromagnetic metals

description: The temperature dependence of the exchange splitting of the energy bands in ferromagnetic iron has been studied at low temperatures by carefully examining the de Haas-van Alphen frequency associated with the minority-spin electron 'lens' sheets of the Fermi surface as a function of temperature between 1° and 4°K. A high resolution phase measurement technique revealed that the variation of the lens frequency over this temperature range was less than one part in 10⁵ and was virtually identical to that measured for the corresponding electron lens in molybdenum. By contrast, a variation of one part in 10⁴ would be expected for the iron lens on the basis of a literal interpretation of the Stoner model, in which the exchange splitting of the energy bands is proportional to the magnetization at all temperatures. The absence of any significant change of the frequency with temperature gives strong evidence that the magnetization in iron decreases almost entirely by spin-wave excitations and that spin waves have negligible effect on the exchange splitting. The latter conclusion is consistent with a recent theory by Edwards for the electron-magnon interaction in itinerant-electron ferromagnets. On the basis of Edwards' theory the experimental technique described in this dissertation can be used to systematically study the single-particle magnetization in metallic ferromagnets without any interference from spin-wave excitations. In particular our experimental results yield an upper bound for the single-particle magnetization in iron at low temperatures. A new set of low-frequency de Haas-van Alphen oscillations has been studied in iron and the experimental results obtained so far suggest the oscillations originate from very small ellipsoidal surfaces centered on the points N of the Brillouin zone. This result points to a particular ordering of the energy bands at N, a feature of the band structure that cannot be predicted reliably from first principles.

description: We calculate the leading-order scattering amplitude of one vector and two tensor gauge bosons in a recently proposed non-Abelian tensor gauge field theory and open superstring theory. The linear in momenta part of the superstring amplitude has identical Lorentz structure with the gauge theory, while its cubic in momenta part can be identified with an effective Lagrangian which is constructed using generalized non-Abelian field strength tensors.
