description: Bismuth has recently attracted interest in connection with Na-ion battery anodes due to its high volumetric capacity. It reacts with Na to form Na$_3$Bi which is a prototypical Dirac semimetal with a nontrivial electronic structure. Density-functional-theory based first-principles calculations are playing a key role in understanding the fascinating electronic structure of Na$_3$Bi and other topological materials. In particular, the strongly-constrained-and-appropriately-normed (SCAN) meta-generalized-gradient-approximation (meta-GGA) has shown significant improvement over the widely used generalized-gradient-approximation (GGA) scheme in capturing energetic, structural, and electronic properties of many classes of materials. Here, we discuss the electronic structure of Na$_3$Bi within the SCAN framework and show that the resulting Fermi velocities and {\it s}-band shift around the $Γ$ point are in better agreement with experiments than the corresponding GGA predictions. SCAN yields a purely spin-orbit-coupling (SOC) driven Dirac semimetal state in Na$_3$Bi in contrast with the earlier GGA results. Our analysis reveals the presence of a topological phase transition from the Dirac semimetal to a trivial band insulator phase in Na$_{3}$Bi$_{x}$Sb$_{1-x}$ alloys as the strength of the SOC varies with Sb content, and gives insight into the role of the SOC in modulating conduction properties of Na$_3$Bi.

description: Inspired by recent measurements of forces and conductances of bipyridine nano-junctions, we have performed density functional theory calculations of structure and electron transport in a bipyridine molecule attached between gold electrodes for seven different contact geometries. The calculations show that both the bonding force and the conductance are sensitive to the surface structure, and that both properties are in good agreement with experiment for contact geometries characterized by intermediate coordination of the metal atoms corresponding to a stepped surface. The conductance is mediated by the lowest unoccupied molecular orbital, which can be illustrated by a quantitative comparison with a one-level model. Implications for the interpretation of the experimentally determined force and conductance distributions are discussed.

description: Disc-driven planet migration is integral to the formation of planetary systems. In standard, gas-dominated protoplanetary discs, low-mass planets or planetary cores undergo rapid inwards migration and are lost to the central star. However, several recent studies indicate that the solid component in protoplanetary discs can have a significant dynamical effect on disc-planet interaction, especially when the solid-to-gas mass ratio approaches unity or larger and the dust-on-gas drag forces become significant. As there are several ways to raise the solid abundance in protoplanetary discs, for example through disc winds and dust-trapping in pressure bumps, it is important to understand how planets migrate through a dusty environment. To this end, we study planet migration in dust-rich discs via a systematic set of high-resolution, two-dimensional numerical simulations. We show that the inwards migration of low-mass planets can be slowed down by dusty dynamical corotation torques. We also identify a new regime of stochastic migration applicable to discs with dust-to-gas mass ratios $\gtrsim 0.3$ and particle Stokes numbers $\gtrsim 0.03$. In these cases, disc-planet interaction leads to the continuous development of small-scale, intense dust vortices that scatter the planet, which can potentially halt or even reverse the inwards planet migration. We briefly discuss the observational implications of our results and highlight directions for future work.

description: The global players in beef production are North America, Brazil, Argentina, Australia and the EU-25. In value-terms, the main exporters are North America, Australia, Brazil and Argentina. Main importers are again North America, Japan and the Far East. Within the framework of the International Farm Comparison Network (IFCN), and using harmonised methods for analysis, a total of 29 typical beef finishing farms in 15 important beef producing countries were analysed. The farms show significant differences in production systems and productivity levels. The highest cost of beef production is found in the EU-countries (US$ 350-500 per 100 kg carcass weight), the lowest in Argentina, Uruguay and Pakistan (US$ 100-130). In the case of trade liberalisation, farms with low costs of production have an incentive to export to markets with higher price levels. A benchmarking example is given for Brazilian, German and Argentinian farms revealing the specific strengths and weaknesses of the typical farms. Further, the time series analysis of identical farms illustrates the necessity of regular cost and price comparisons. The future potential of beef production depends on availability of land, possibilities for intensifying production and the competition with other land uses. Whether an increase in production leads to a net trade surplus depends mainly on the development of the demand for beef.

description: The five major agricultural producing provinces are compared in terms of farm labour and management incomes, return on investment to farm capital, total farm family income, and farm family net worth. In each province, comparisons are made with non-farm incomes, investment returns and net worth levels. The results show that farm family incomes in Canada are much better today than 30 years ago, returns on farmland investment are very comparable to average stock market returns, and average farm family net worth is significantly higher than the average for all families. The conclusion is that Canadian farmers have adapted well to declining commodity prices mainly by being adapters of and investors in new technologies, allowing them to increase farm size (increased cost efficiencies) and by diversifying their income sources to include more off-farm income.

description: Motivated and competent team members are a vital part of Agile Software development and make or break any project's success. Motivation is fostered by continuous progress and recognition of efforts. These concepts are founding pillars of the Scrum methodology, which focuses on self-organizing teams. The types of contributions Scrum development team members make to a project's progress are not only technical. However, a comprehensive model comprising the varied contributions in modern software engineering teams is not yet established. We propose a model that incorporates contributions of all Scrum roles, explicitly including those which are not directly related to project artifacts. It improves the visibility of performed tasks, acts as a starting point for team retrospection, and serves as a foundation for discussion in the research community.

description: This article examines the role of imperfect competition in determining total factor productivity growth (TFPG) by bringing together a New Empirical Industrial Organization (NEIO) model and the TFPG model of Nadiri and Mamuneas (1998). Applying the integrated model to 1973-92 data from 29 food processing industries revealed that changes in markups, economies of scale, and demand growth contributed positively to TFPG while the disembodied technical change was a negative contributor. Furthermore, the TFPG estimates are starkly different from the conventional (Solow's residual) TFPG measures, underscoring the need to account for imperfect competition, returns to scale, and demand in analyses of this type.

description: This report analyzes the economic impact of price fixing in the wet corn milling industry on consumers in the State of Michigan. Two of the companies who produce citric acid have pleaded guilty to fixing its price. In this report we assume that price fixing also occurred among HFCS producers. Given the structure of the corn wet milling industry and the direct purchaser industries, the overcharge is essentially uniform across buyers and selling arrangements. We develop an actual economic model of price transmission based upon the three facts: 1) The overcharge as a percent of the processed product value at wholesale and at retail is small, 2) Fixed proportion technology, and 3) consumers have imperfect information about prices so a small price change has no effect on their purchase behavior. These facts establish that 100 percent or more of the common overcharge will be passed through to consumers. In a more general economic model, we analyze pass through when consumer demand is not perfectly inelastic. For different strategies (profit maximization, sales maximization subject to a target level of profit, and loss leader strategies) and for different market structures (competitive, monopoly, oligopoly), the rate of pass through is 100 percent or greater given certain documented characteristics of the industries in this case. Given the prior points consumer damages are the common overcharges for each commodity times the amount of the commodity sold during the damage period. This is a lower bound estimate of consumer damages because pass through may well be greater than 100%.

description: Modern observational and analytic techniques now enable the direct measurement of star formation histories and the inference of galaxy assembly histories. However, current theoretical predictions of assembly are not ideally suited for direct comparison with such observational data. We therefore extend the work of prior examinations of the contribution of ex-situ stars to the stellar mass budget of simulated galaxies. Our predictions are specifically tailored for direct testing with a new generation of observational techniques by calculating ex-situ fractions as functions of galaxy mass and morphological type, for a range of surface brightnesses. These enable comparison with results from large FoV IFU spectrographs, and increasingly accurate spectral fitting, providing a look-up method for the estimated accreted fraction. We furthermore provide predictions of ex-situ mass fractions as functions of galaxy mass, galactocentric radius and environment. Using $z=0$ snapshots from the 100cMpc$^3$ and 25cMpc$^3$ EAGLE simulations we corroborate the findings of prior studies, finding that ex-situ fraction increases with stellar mass for central and satellite galaxies in a stellar mass range of 2$\times$10$^{7}$ - 1.9$\times$10$^{12}$ M$_{\odot}$. For those galaxies of mass M$_*$>5$\times$10$^{8}$M$_{\odot}$, we find that the total ex-situ mass fraction is greater for more extended galaxies at fixed mass. When categorising satellite galaxies by their parent group/cluster halo mass we find that the ex-situ fraction decreases with increasing parent halo mass at fixed galaxy mass. This apparently counter-intuitive result may be the result of high passing velocities within large cluster halos inhibiting efficient accretion onto individual galaxies.

Publisher: name: Swinburne
Year: 2024

description: In this thesis, a dermal 3D cell culture model was developed to study light-matter interactions in microscopy, using human fibroblast cells (BJ5ta) embedded in collagen or gelatin methacryloyl (GelMA). The feasibility of endoscopy tools for monitoring cells in living 3D systems was investigated using confocal endomicroscopy, FT-NIR endospectroscopy and Raman endospectroscopy. The model was then extended to study fibrosis, using TGF-β1, and compared against human cirrhotic liver tissue biopsies. Finally, the model was adapted to study how the thermal lens generation affects mechanical contrast in photothermal microscopy. This thesis contributed to advancing the understanding of light-matter interactions that occur when imaging complex 3D cell culture models.
A phenomenological investigation of the coaching experience : implications for counselling psychology
Creators: name: Dhaliwal, Indira
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to examine the subjective experience of individuals who had experienced coaching within the last year. Since coaching is a relatively new phenomenon, this study was exploratory in nature. Therefore, a qualitative phenomenological methodology was used to guide the data collection and analysis. The research question that guided this study was: "What is the lived experience of individuals who have been coached?" Data was collected through in-depth semi-structured interviews with a volunteer sample of six participants. The main criterion for recruitment of participants included those individuals who had been coached for a minimum of five months or at least 15 sessions. The interviews were audio-taped and transcribed verbatim. Using Colaizzi's (1978) method of data analysis, individual themes and themes common to all six participants were extracted. The results highlight the experiences of individuals, thereby contributing to a discussion of the comparisons and contrasts between coaching and counselling psychology.

description: Active feedback stabilization of the dominant resistive wall mode (RWM) for an ITER H-mode scenario at high plasma pressure using infinite-horizon model predictive control (MPC) is presented. The MPC approach is closely-related to linear-quadratic-Gaussian (LQG) control, improving the performance in the vicinity of constraints. The control-oriented model for MPC is obtained with model reduction from a high-dimensional model produced by CarMa code. Due to the limited time for on-line optimization, a suitable MPC formulation considering only input (coil voltage) constraints is chosen, and the primal fast gradient method is used for solving the associated quadratic programming problem. The performance is evaluated in simulation in comparison to LQG control. Sensitivity to noise, robustness to changes of unstable RWM dynamics, and size of the domain of attraction of the initial conditions of the unstable modes are examined.

description: This paper documents the extent of cooperative penetration into branded dairy product markets and presents case study evidence on competitive strategies in the skim/low fat milk, whole milk, cottage cheese, butter, margarine, and ice cream markets. We employ data for 51 local market areas from the Information Resources, Inc. "Supermarket Review" data base for 1988 and 1989. Using national data, we identify the twenty top brands (by volume sales) and all cooperatives that market one or more brands in each of the above categories, and report their national market shares, averages prices, number of local markets in which they are sold, and a summary of their local rankings. Using local data for selected brands, we graphically analyze how prices, quantities, and shares change over time in particular markets. We find that cooperatives have much stronger positions in local markets than their national market shares indicate. When looking at the brand share-price relationships for particular brands across local markets, we find examples of positive, negative, and no relationships.

description: Pulsar wind nebulae are now well established as important probes both of neutron stars' relativistic winds and of the surrounding interstellar medium. Amongst this diverse group of objects, pulsar bow shocks have long been regarded as an oddity, only seen around a handful of rapidly moving neutron stars. However, recent efforts at optical, radio and X-ray wavelengths have identified many new pulsar bow shocks, and these results have consequently motivated renewed theoretical efforts to model these systems. Here I review the new results and ideas which have emerged on these spectacular systems, and explain how bow shocks and "Crab-like" nebulae now form a consistent picture within our understanding of pulsar winds.

description: We examine the question of adaptive firm conduct using longitudinal product-level data from three large horizontal mergers in the food manufacturing industry. Our model is grounded in a "poststructural" view of competition that we deduce from recent writings from the fields of strategy, organizational ecology, and industrial organization. Consistent with this model, we find that the influence of horizontal merger on product performance (i.e., rent) varies with the product niche, time, the specific firms that merged, and dominance of the product, and its market scope.

description: Abridged: Debris disks are valuable systems to study dust properties. Because they are optically thin at all wavelengths, we have direct access to the properties of dust grains. One very promising technique to study them is to measure their phase function. Disks that are highly inclined are promising targets as a wider range of scattering angles can be probed. The phase function is usually either inferred by comparing the observations to synthetic disk models assuming a parametrized phase function, or estimating it from the surface brightness of the disk. We argue here that the latter approach can be biased due to projection effects leading to an increase in column density along the major axis of a non flat disk. We present a novel approach to account for those column density effects. The method remains model dependent, as one still requires a disk model to estimate the density variations as a function of the scattering angle. This method allows us however to estimate the shape of the phase function without having to invoke any parametrized form. We apply our method to SPHERE/ZIMPOL observations of HR\,4796 and highlight the differences with previous measurements. Our modelling results suggest that the disk is not vertically flat at optical wavelengths. We discuss some of the caveats of the approach, mostly that our method remains blind to real local increase of the dust density, and that it cannot yet be readily applied to angular differential imaging observations. Similarly to previous studies on HR\,4796, we still cannot reconcile the full picture using a given scattering theory to explain the shape of the phase function, a long lasting problem for debris disks. Nonetheless, we argue that similar effects as the ones highlighted in this study can also bias the determination of the phase function in total intensity.

description: Magnetic impurities with sufficient anisotropy could account for the observed strong deviation of the edge conductance of 2D topological insulators from the anticipated quantized value. In this work we consider such a helical edge coupled to dilute impurities with an arbitrary spin $S$ and a general form of the exchange matrix. We calculate the backscattering current noise at finite frequencies as a function of the temperature and applied voltage bias. We find that in addition to the Lorentzian resonance at zero frequency, the backscattering current noise features Fano-type resonances at non-zero frequencies. The widths of the resonances are controlled by the spectrum of corresponding Korringa rates. At a fixed frequency the backscattering current noise has non-monotonic behaviour as a function of the bias voltage.

Constraining the mass transfer in massive binaries through progenitor evolution models of Wolf-Rayet+O binaries

description: Since close WR+O binaries are the result of a strong interaction of both stars in massive close binary systems, they can be used to constrain the highly uncertain mass and angular momentum budget during the major mass transfer phase. We explore the progenitor evolution of the three best suited WR+O binaries HD 90657, HD 186943 and HD 211853, which are characterized by a WR/O mass ratio of $\sim$0.5 and periods of 6..10 days. We are doing so at three different levels of approximation: predicting the massive binary evolution through simple mass loss and angular momentum loss estimates, through full binary evolution models with parametrized mass transfer efficiency, and through binary evolution models including rotation of both components and a physical model which allows to compute mass and angular momentum loss from the binary system as function of time during the mass transfer process. All three methods give consistently the same answers. Our results show that, if these systems formed through stable mass transfer, their initial periods were smaller than their current ones, which implies that mass transfer has started during the core hydrogen burning phase of the initially more massive star. Furthermore, the mass transfer in all three cases must have been highly non-conservative, with on average only $\sim$10% of the transferred mass being retained by the mass receiving star. This result gives support to our system mass and angular momentum loss model, which predicts that, in the considered systems, about 90% of the overflowing matter is expelled by the rapid rotation of the mass receiver close to the $Ω$-limit, which is reached through the accretion of the remaining 10%.

description: We report the results of a low temperature (T >= 50 mK) and high field (H <= 180 kOe) study of the Hall resistivity in single crystals of YbAgGe, a heavy fermion compound that demonstrates field-induced non-Fermi-liquid behavior near its field-induced quantum critical point. Distinct features in the anisotropic, field-dependent Hall resistivity sharpen on cooling down and at the base temperature are close to the respective critical fields for the field-induced quantum critical point. The field range of the non-Fermi-liquid region decreases on cooling but remains finite at the base temperature with no indication of its conversion to a point for T -> 0. At the base temperature, the functional form of the field-dependent Hall coefficient is field direction dependent and complex beyond existing simple models thus reflecting the multi-component Fermi surface of the material and its non-trivial modification at the quantum critical point.

description: We show that the theory of self-adjoint differential equations can be used to provide a satisfactory solution of the inverse variational problem in classical mechanics. A Newtonian equation when transformed to the self-adjoint form allows one to find an appropriate Lagrangian representation (direct analytic representation) for it. On the other hand, the same Newtonian equation in conjunction with its adjoint provides a basis to construct a different Lagrangian representation (indirect analytic representation) for the system. We obtain the time-dependent Lagrangian of the damped Harmonic oscillator from the self-adjoint form of the equation of motion and at the same time identify the adjoint of the equation with the so called Bateman image equation with a view to construct a time-independent indirect Lagrangian representation. We provide a number of case studies to demonstrate the usefulness of the approach derived by us. We also present similar results for a number of nonlinear differential equations by using an integral representation of the Lagrangian function and make some useful comments.

description: We study the dependence of the galaxy contents within halos on the halo formation time using two galaxy formation models, one being a semianalytic model utilizing the halo assembly history from a high resolution N-body simulation and the other being a smoothed particle hydrodynamics simulation including radiative cooling, star formation, and energy feedback from galactic winds. We confirm the finding by Gao et al. that at fixed mass, the clustering of halos depends on the halo formation time, especially for low-mass halos. This age dependence of halo clustering makes it desirable to study the correlation between the occupation of galaxies within halos and the halo age. We find that, in halos of fixed mass, the number of satellite galaxies has a strong dependence on halo age, with fewer satellites in older halos. The youngest one-third of the halos can have an order of magnitude more satellites than the oldest one-third. For central galaxies, in halos that form earlier, they tend to have more stars and thus appear to be more luminous, and the dependence of their luminosity on halo age is not as strong as that of stellar mass. The results can be understood through the star formation history in halos and the merging of satellites onto central galaxies. The age dependence of the galaxy contents within halos would constitute an important ingredient in a more accurate halo-based model of galaxy clustering.

description: Interest in establishing nationally uniform certification, labeling, and management standards for organic products grew out of concern that the existence of multiple standards led to consumer and supply chain confusion about, and lack of confidence in, these products. The National Organic Program Final Rule, issued in December 2000, is the result of this interest. We analyze the certification system that was in place prior to the new national rule to evaluate the extent of differences between certification standards and how the national rule is likely to impact the market for organic products. Our analysis suggests that most differences among US certification standards were minor. Also, the most important impacts of the national standard may be in facilitating trade in ingredients and products certified by different certifiers, increasing buyer confidence, and facilitating exports. However, the national rule may decrease the ability of organic certifiers and consumers to place differing emphasis on the multiple goals of organic production and may decrease the flexibility of organic standards to respond to changing market conditions, including new technologies.

Epigenetic and geometrical characterisation of cancer cell populations: A personalised-medicine oriented mathematical study of tumour evolutionary dynamics and therapies
Creators: name: Chiari, Giulia
Publisher: name: Swinburne
Year: 2024

description: The thesis focuses on oncological mathematics, developing various mathematical models with distinct theoretical approaches to describe the evolution of tumour masses. It considers the epigenetic and geometric characterisation of cancer cell populations, their interaction with the environment, and the application of therapies. Key objectives achieved include the qualitative and quantitative reproduction of clinical observations using biologically consistent models, the utilisation of models for predictive purposes, and the establishment of design strategies for patient-specific protocols. This work introduces novel modelling approaches, contributes to a deeper understanding of tumour dynamics, and supports the advancement of personalised medicine.
Detection of satellite remnants in the Galactic Halo with Gaia - I. The effect of the Galactic background, observational errors and sampling

description: We address the problem of identifying remnants of satellite galaxies in the halo of our galaxy with Gaia data. The remnants have to be extracted from a very large data set (of order 10^9 stars) in the presence of observational errors and against a background population of Galactic stars. We address this issue through a numerical simulation of the Gaia catalogue with a realistic number of entries. The Galaxy model includes separate light distributions and kinematics for the bulge, disc and stellar halo. Our catalogue contains 3.5x10^8 stars. We perform tree code 10^6-body simulations of satellite dwarf galaxies in orbit around a rigid mass model of the Galaxy. The shrinking satellite cores and tidal tails are added to the Monte Carlo simulation of the Gaia catalogue. When combining the Milky Way and dwarf galaxy models we include the complication that the luminosity function of the satellite is probed at various depths as a function of position along the tidal tails. The combined models are converted to a synthetic Gaia catalogue using a detailed model for the expected astrometric and radial velocity errors, depending on magnitude, colour and sky position of the stars. We explore the feasibility of detecting tidal streams in the halo using the energy versus angular momentum plane. A straightforward search in this plane will be very challenging. The background population and the observational errors make it difficult to detect tidal streams as discrete structures in the E-Lz plane. The propagation of observational errors leads to apparent caustic structures in the integrals of motion space that may be mistaken for physical entities. Any practical search strategy will have to use a combination of pre-selection of high-quality data and complementary searches using the photometric data from Gaia. (abridged)

description: The work is devoted to the analysis of the surface photometric observations of two total lunar eclipses in 2004. The lunar surface relative brightness distribution inside the umbra was used to retrieve the vertical distribution of aerosol extinction of the solar radiation expanding by a tangent path and its dependence on the location at the limb of the Earth. The upper altitude of troposphere aerosol layer was estimated for different latitude zones. The correlation between additional aerosol extinction in the upper troposphere and cyclones was investigated.

description: Using ab initio thermodynamics we compile a phase diagram for the surface of Fe3O4(001) as a function of temperature and oxygen pressures. A hitherto ignored polar termination with octahedral iron and oxygen forming a wave-like structure along the [110]-direction is identified as the lowest energy configuration over a broad range of oxygen gas-phase conditions. This novel geometry is confirmed in a x-ray diffraction analysis. The stabilization of the Fe3O4(001)-surface goes together with dramatic changes in the electronic and magnetic properties, e.g., a halfmetal-to-metal transition.

description: This article decomposes the impact of imports on domestic price-cost margins into separate price and cost effects. Using data from 24 food-processing industries, the empirical results show that although the direct impact of imports on prices is always negative, a positive net impact on price-cost margins occurs in industries characterized by low own-price elasticity of demand and diseconomies of scale. Further results show that the disciplining effect of imports is more preponderant the lower the degree of domestic competition.
