title: The Role of GPR84 in Medium-chain Saturated Fatty Acid Taste Transduction
Creators: name: Liu, Yan
Publisher: name: Utah State University
Year: 2016

description: Previous research has shown the gustatory recognition of the long-chain unsaturated fatty acids. In this study, I showed for the first time that medium-chain saturated fatty acids (MCFAs) are effective taste stimuli at both the cellular and behavioral levels. The mechanisms of gustatory recognition of MCFAs in mice were also partially elucidated using pharmaceutical approaches. The inward currents induced by capric acid in mouse taste cells were significantly inhibited by the antagonists of G-protein signaling, protein kinase A (PKA), and protein kinase C (PKC), but they were not affected by the phospholipase C (PLC) and phosphodiesterase (PDE) inhibitors, which suggested that MCFA taste transduction involves G-protein, PKA, and PKC activation, but does not involve PLC and PDE. Furthermore, transient receptor potential channel type M5 (TRPM5) knockout mice showed unaffected cellular and behavioral responses, indicating MCFA taste transduction in mice was TRPM5-independent. The receptor of MCFAs on taste cells was also investigated in this study. Previous research has shown that GPR84 is a novel G protein-coupled receptor (GPCR) activated by MCFAs with 9 to 14 carbons, and the real-time PCR results supported the mRNA expression of GPR84 in mouse taste cells. Therefore, GPR84 is a good candidate for the MCFA receptor in taste cells. By using a cell line that had an inducible GPR84 + Gqi9 (a chimeric G-protein), ligand specificity experiments showed that the ligands of GPR84 included saturated fatty acids with 6 to 12 carbons and other fatty acids (oleic acid, arachidic acid) previously not known to activate this receptor. Compared to wild type cells, taste cells lacking GPR84 showed significantly lower calcium responses and inward currents to capric acid (C10), and GPR84 knockout mice showed decreased taste sensitivities to both lauric (C12) and capric acids behaviorally, suggesting that GPR84 plays an essential role in MCFA taste transduction process.
title: Analyzing Irrigation District Water Productivity by Benchmarking Current Operations Using Remote Sensing and Simulation of Alternative Water Delivery Scenarios
Creators: name: van Opstal, Jonna D.
Publisher: name: Utah State University
Year: 2016

description: Irrigation systems are designed to deliver water to crops, but their efficacy varies widely due to operational decisions, weather variability, and water availability. The operation of an irrigation system is studied in this dissertation to determine irrigation performance and potential for improvement.Satellite remote-sensing was used to determine inter-annual variability in crop evapotranspiration and link it with weather patterns and operational decisions. A decade was studied to include several dry, wet and average years of snowfall. It was found that the irrigation district has the capacity to buffer a dry year, but crop evapotranspiration patterns indicated that the buffer capacity of the irrigation district is limited in a second dry year.
Studying the current operations of an irrigation system also requires an analysis of the spatial variability within the system to identify potential areas for improvement. Achieving such information is challenging due to the spatial heterogeneity between farm fields. The Ador irrigation system simulation model is used in this study with satellite remote sensing data, which were combined in the calibration and validation process to ease the re-adjustment of management parameters. This approach provides a cost-effective and innovative method for model simulation when field observations are limited.
Alternative water delivery scenarios were simulated with the Ador irrigation system simulation model to quantify changes in the water balance, irrigation performance, and water productivity. Results for implementing a minimal irrigation time indicated that irrigation events occurred with a higher frequency and reduced crop water stress. Water productivity for the irrigation district increased substantially in this scenario, whilst district water savings were achieved by diverting less irrigation water. Advantages are only achieved if farmers collectively make the decision to change.
A water accounting analysis is required to examine if water savings are achieved at basin scale. There is a potential for the rebound effect to occur, which suggests that an increase of water efficiency causes the increase of water consumption. Simulation results indicated that if the efficiency is increased through improvements of the water delivery, the water consumption increased. Water savings achieved by reducing irrigation diversions did not compensate for the decrease in drainage that downstream users depend on.

description: The critical behavior of the chiral quark-meson model is studied within the Functional Renormalization Group (FRG). We derive the flow equation for the scale dependent thermodynamic potential at finite temperature and density in the presence of a symmetry-breaking external field. Within this scheme, the critical scaling behavior of the order parameter, its transverse and longitudinal susceptibilities as well as the correlation lengths near the chiral phase transition are computed. We focus on the scaling properties of these observables at non-vanishing external field when approaching the critical point from the symmetric as well as from the broken phase. We confront our numerical results with the Widom-Griffiths form of the magnetic equation of state, obtained by a systematic epsilon-expansion of the scaling function. Our results for the critical exponents are consistent with those recently computed within Lattice Monte-Carlo studies of the O(4) spin system.

description: This thesis proposes a modiﬁcation of trajectory shaping guidance to provide more accurate path convergence in curved paths. The object of this thesis is to apply this simple guidance law to platooning control to ensure all vehicles in the platoon converge to a desired constant radius path at a desired vehicle separation distance. To show the viability of this new guidance law, it is shown mathematically to be exponentially stable. It is also conﬁrmed through simulations and on ground robots.

description: We report reliable transport of 9Be+ ions through a 2-D trap array that includes a separate loading/reservoir zone and an "X-junction". During transport the ion's kinetic energy in its local well increases by only a few motional quanta and internal-state coherences are preserved. We also examine two sources of energy gain during transport: a particular radio-frequency (RF) noise heating mechanism and digital sampling noise. Such studies are important to achieve scaling in a trapped-ion quantum information processor.

Using compatible actions, we construct a new resolution to compute the cohomology of semi-direct products of Lie algebras. We also give an alternative way to construct the Hochschild-Serre spectral sequence associated to a split extension of finite dimensional Lie algebras and obtain a sharper bound for the length of this spectral sequence.

title: Political Parties and Direct Democracy: An Analysis of the 2015 Greek Referendum
Creators: name: Hansen, Megan E.
Publisher: name: Utah State University
Year: 2016

description: On July 5, 2015, Greek voters were asked to vote on whether the country should accept the terms of austerity offered by the European Union for bailout from the country’s financial crisis. With a turnout rate of 62.5% overall, 61.3% of Greeks voted “no.” While a majority of voters in every district opposed the bailout’s terms, the margin against the proposed austerity measures ranged from 51.2% in Lakonias to 73.8% in Chanion. This paper explores whether political parties influenced Greek voters’ decisions to accept or reject the EU's budgetary reforms. We first review the literature relevant to that question, focusing on whether party platforms are merely “cheap talk” or instead are salient in determining electoral outcomes. We then test our hypotheses empirically at the voting district level.
In this model, our key independent variable is party influence, which is measured by party vote shares in the nationwide election held in January of 2015. The dependent variable is the percentage that voted “no” to austerity in July 2015 in each of Greece’s 56 electoral districts. We also control for average age and the unemployment rate across regions, as well as the fraction of first-time voters in each electoral district. After conducting simple regression analysis, we report evidence that a pro-austerity party (New Democracy) was a significant factor impacting the results of the referendum. This research finding bolsters the claim that parties can shape electoral outcomes on questions decided by an institution of direct democracy.
title: A Light in the Dark: Luminescence Dating Intermountain Ware Ceramics from Four Archaeological Sites in Northwestern Wyoming
Creators: name: Ideker, Carlie J.

Year: 2016

description: Late Period (years), high-altitude (>2600 m asl) archaeological sites in northwestern Wyoming prove difficult to date with traditional methods. The presence of Intermountain Ware ceramics at these sites presents an opportunity to use single-grain optically stimulated luminescence (OSL) to date vessel manufacture. These OSL ages also date site occupation as the vessels’ use-life is encapsulated within the standard error of the technique. This thesis develops a protocol to date quartz temper of Intermountain Ware sherds. Additionally, it investigates potential post-depositional thermal resetting of luminescence signals by wildfires. Ceramic sherd samples were obtained from four sites in northwestern Wyoming: Boulder Ridge, High Rise Village, Caldwell Creek, and Platt. Each site, except Caldwell Creek, has existing radiocarbon ages that provide independent age control. Additionally, all sites except Platt were impacted by past wildfires of varying intensity and consequently provide a test of the thermal resetting capabilities of wildfires.The Platt site is also the only site not located at high altitude and therefore, the sample from this site serves as a control in this study.
Luminescence results demonstrate single-grain OSL dating of quartz temper from Intermountain Ware ceramics can provide improved accuracy and precision over radiocarbon dating when sherds are not adversely affected by wildfires. These results underscore the need for cultural resource managers to sample from subsurface contexts when inventorying sites impacted by high-intensity wildfires or to locate and identify sites with strong potential for high-intensity wildfires and date them prior to eventual burning. These results also validate single-grain OSL dating of ceramic temper as a valuable chronometric tool for cultural resource managers and archaeologists seeking to build and refine existing site and regional chronologies.

description: Cellulose nanofibers are green nanomaterials because of their biodegradability and sustainability, they are also attractive structural materials because of their high mechanical performance. For further expansion of their application and acquisition of their reliability, mechanical reinforcement and functionalization of cellulose nanofiber materials are required. In this work, we focused on the mechanical properties and thermal conductivities of composites of cellulose nanofibers and a nanodiamond (ND). Compared with graphene oxides, which are conventional two-dimensional nanocarbon fillers in aqueous media, natural diamond possesses a much larger modulus. It also has the highest thermal conductivity among all the elemental substances. The ND possesses hydrophilic oxygen functional groups at the surface, following a high dispersion in aqueous media and the rigid diamond structure at the core. In this work, the ND resulted in an increased mechanical reinforcement and enhancement of the thermal conductivity of the cellulose nanofiber, while keeping the high visible light transmittance originating from the latter. In particular, 2,2,6,6-tetramethylpiperidine 1-oxyl-oxidized cellulose nanofibers were reinforced more effectively than quaternary ammonium cellulose nanofibers because of the stronger interaction with the ND and higher dispersibility of the ND. Accordingly, it was proved that the cellulose nanofiber/ND composite was a promising high-strength and high-thermal-conductive material.

description: Questioning is an instructional strategy that serves many purposes for teachers and students. The purpose of this study is to evaluate the questioning sequence of moving from low- to high-level questions to support students’ reading text-based comprehension.After engaging in didactic instruction and practice in the TeachLivE™ Lab, teacher participants implemented low- and high-level question sequences during reading instruction with elementary students. Teacher performance was measured as a rate of question sequences in a multiple baseline design across two participants. Students’ verbal responses were assessed based on how they related a personal experience back to the text.Based on the findings, teachers effectively improved the use of questioning sequences.This instructional practice made a significant impact on low performing students. Overall students increased the quantity of c-units and accuracy.
A survey and synthesis of the literature available on anxiety and strategies with coping with anxiety in relation to the musical performer

description: The desire to undertake this specific research project stems from my interest, as a musician, a wind player, of the effect of nerves and anxiety in musical performance and more importantly, in the current coping strategies that are suggested and detailed in the available literature. The aim of the project is to develop a sound knowledge of this topic, of dealing with musical performance anxiety by reading, understanding and then providing a detailed survey and synthesis of what I consider to be the most current and relevant material available. This study will provide simple and concise overviews of a number of current theories and the best strategies to be adopted to cope with anxiety when faced with a musical performance. Nearly all musicians will have to perform at some stage, and most of them will experience some degree of anxiety along with performance. Therefore, it is imperative that those of them that do experience any of the; ‚Äöphysiological; ‚Äöcognitive; ‚Äöbehavioural; and ‚Äöpsychological symptoms of anxiety are aware of and able to adopt the relevant coping strategies to eliminate or at least reduce performance anxiousness. I hope, by this project to gain a knowledge in this area, and having gained this knowledge I hope to be able to evaluate the different studies and approaches and then, in my own performances adopt those that I feel are the most appropriate.

description: Accurate description of the topography of active faults surfaces represents an important geophysical issue because this topography is strongly related to the stress distribution along fault planes, and therefore to processes implicated in earthquake nucleation, propagation, and arrest. With the recent development of Light Detection And Ranging (LIDAR) apparatus, it is now possible to measure accurately the 3D topography of rough surfaces with a comparable resolution in all directions, both at field and laboratory scales. In the present study, we have investigated the scaling properties including possible anisotropy properties of several outcrops of two natural fault surfaces (Vuache strike-slip fault, France, and Magnola normal fault, Italy) in limestones.

description: Two of the most striking and yet unresolved manifestations of the hidden order (HO) in URu2Si2, are associated on one hand with the double-step metamagnetic transitions and on the other with the giant anomalous Nernst signal. Both are observed when a magnetic field is applied along the c-axis. Here we provide for the first time a unified understanding of these puzzling phenomena and the related field-temperature (B-T) phase diagram. We demonstrate that the HO phase at finite fields can be explained with a chiral dxy+idx2-y2 spin density wave, assuming that the zero field HO contains only the time-reversal symmetry preserving idx2-y2 component. We argue that the presence of the field-induced chiral HO can be reflected in a distinctive non-linear B-dependence of the Kerr angle, when a Kerr experiment is conducted for finite fields. This fingerprint can be conclusive for the possible emergence of chirality in the HO.

description: Code search is a widely used technique by developers during software development. It provides semantically similar implementations from a large code corpus to developers based on their queries. Existing techniques leverage deep learning models to construct embedding representations for code snippets and queries, respectively. Features such as abstract syntactic trees, control flow graphs, etc., are commonly employed for representing the semantics of code snippets. However, the same structure of these features does not necessarily denote the same semantics of code snippets, and vice versa. In addition, these techniques utilize multiple different word mapping functions that map query words/code tokens to embedding representations. This causes diverged embeddings of the same word/token in queries and code snippets. We propose a novel context-aware code translation technique that translates code snippets into natural language descriptions (called translations). The code translation is conducted on machine instructions, where the context information is collected by simulating the execution of instructions. We further design a shared word mapping function using one single vocabulary for generating embeddings for both translations and queries. We evaluate the effectiveness of our technique, called TranCS, on the CodeSearchNet corpus with 1,000 queries. Experimental results show that TranCS significantly outperforms state-of-the-art techniques by 49.31% to 66.50% in terms of MRR (mean reciprocal rank).

description: Celluloses have attracted much attention as sustainable and abundant materials. Herein, we focus on nanocomposites based on the oxidation-treated nano-sized fibrillated celluloses, namely TOCNs. The silver nanoparticles (AgNPs) were prepared in TOCN aqueous dispersion. Generally, the AgNPs are quickly agglomerated after preparation. For the inhibition of the agglomeration of AgNPs, it is required that AgNPs were prepared under the chelation of TOCN, followed by reduction therein. Therefore, AgNPs possessed the nano-scaled radii and aligned along the TOCN from the atomic force microscopic measurements. The thermal stabilities and mechanical properties were increased. The anisotropic thermal conductivities originated from the orientation of TOCN in nanocomposites were observed. The loading of the large amounts of AgNP fillers led to the drastic increase of the thermal and electrical conductivities. The conductive paths of heat and electron were formed by the contact of AgNP with each other. We functionalized the TOCN papers through the loading of AgNPs and the obtained nanocomposites sheets served as conductors.
title: The Effect of Weight on the Perceptions of and Attitudes Toward Individuals with Anorexia Nervosa
Creators: name: White, Allison E.
Publisher: name: Utah State University
Year: 2016

description: The present study investigated perceptions, attitudes, and beliefs toward individuals with anorexia nervosa (AN) of varying weight. The primary aim was to examine the associations between eating disorder symptom level and stigma toward eating disorders, perceptions of acceptability/desirability of AN, and perceptions of severity of AN. The second aim was to investigate the impact of body weight on males’ and females’ perceptions and attitudes toward AN, specifically on their stigma toward eating disorders, perception of the severity of AN, and perception of acceptability or desirability of AN behaviors and characteristics. Two-hundred fifty-seven university students (187 females, 70 males, mean age = 22.5, SD = 6.59) in undergraduate courses participated in the online study, and were randomly assigned to view one of three underweight female figures (extremely thin, moderately thin, and mildly thin). Participants read a vignette describing an individual meeting full diagnostic criteria for anorexia and completed measures assessing stigma toward individuals with AN and eating disorder symptomatology.
Regarding the first aim, it was hypothesized that an inverse relationship would emerge between eating disorder pathology in participants and stigmatizing attitudes and beliefs. In support of the hypothesis, findings revealed that increased acceptability of AN and greater perceptions of AN severity were associated with higher levels of eating disorder symptoms. In contrast to the hypothesis, current self-reported eating disorder symptoms were not significantly associated with lower levels of eating disorder stigma. It was also hypothesized that female participants would perceive AN as more positive and acceptable, and as less severe than male participants. The hypothesis was partially supported in that females indicated less stigma toward EDs and reported perceiving AN to be more serious than males. Greater acceptability was not more common among women. In regard to the second aim, there was no significant group differences found in eating disorder stigma, perceived acceptance of AN, and perceived severity of AN according to weight conditions, which was contrary to expectations. Implications of the study are discussed in terms of future research.

description: We described details of a method to estimate with good accuracy the mosaic angle distributions of microcrystallites (platelets) in exfoliated graphite like Grafoil which is commonly used as an adsorption substrate for helium thin films. The method is based on analysis of resonance field shifts in continuous-wave (CW) NMR spectra of $^{3}$He ferromagnetic monolayers making use of the large nuclear polarization of the adsorbate itself. The mosaic angle distribution of a Grafoil substrate analyzed in this way can be well fitted to a gaussian form with a $27.5\pm2.5$ deg spread. This distribution is quite different from the previous estimation based on neutron scattering data which showed an unrealistically large isotropic powder-like component.

Study of 19F-1H couplings in nuclear magnetic resonance.

description: A new method of synthesizing organic fluorides stereospecifically was developed; the elements 'BrF' and 'IF' were added quantitatively across the double bond of simple olefins such as cyclohexene, using elemental halogen and silver fluoride at room temperature in benzene. Application of this reaction to the activated olefin, acenaphthylene, resulted in a variety of products, depending on solvent; with pure acetonitrile solvent, quantitative 'BrF' addition occurs, but with an increasing proportion of benzene various side reactions take place, including difluorination and dimerization. Another series of compounds was synthesized from fluoro- acenaphthylene by various addition and substitution reactions, and all together fifteen acenaphthene fluorides were made, including thirteen new compounds. The ¹H and ¹⁹F N.M.R. spectra of these substances were measured and a set of ³JHF values obtained for a wide variation in the electronegativity of the substituents, and for two values of dihedral angle (0°and 100°). This data showed that the dependence of ³JHF upon electronegativity was far from linear, as had hitherto been supposed, but rather exponential, which is in retrospect more logical. Application of this data on ³JHF to some flexible systems, derivatives of indene and benzofuran, allowed their conformations to be determined. In all cases the pucker of the five-membered ring is small (∼25°), except in the cis-bromofluoride of benzofuran where it is much larger, (45-50°). A separate study was made of the conformational inversion of trans-1-fluoro-2-iodocyclohexane (I) and its specifically deuterated analogue, derived from 3,3,6,6-tetradeutero-cyclohexene. Several methods were employed to measure the position of the conformational equilibrium and this permitted a comparison of the methods themselves. It was found that all chemical shifts and coupling constants were temperature dependent, those involving ¹⁹F being particularly susceptible. The only reliable methods were found to be area measurements (at -90°C), linewidth measurements (at -45°C), and temperature-corrected ¹⁹F chemical shift measurements; thus the compound in question was found to have a preference for the diequatorial form, with ∆G° = 0.650 ± 0.025 kcal./mole (at -90°C to 0°C), and a near zero entropy, ∆S° = 0.0 ± 0.5 e.u. This value of ∆G° is only 0.1 kcal./mole smaller than the sum of the A-values for iodine and fluorine, and indicates that the repulsion between these two halogens in the diequatorial form is quite small, about one tenth that between iodine and chlorine, or between chlorine and chlorine, etc. A kinetic study of I was made by applying the general lineshape equation of Gutowsky and Holm for two-site exchange; calculated line-widths and positions were matched to the experimental ¹⁹F spectra (with all ¹H couplings removed by irradiation) at various temperatures, and thus an Arrhenius plot was made and activation parameters derived. ∆FƗ = 10.38 kcal./mole; ∆SƗ = 2.1 e.u.
Development and characterisation of a colorimetric binding phase for the diffuse gradients in thin films technique
Creators: name: McGifford, RW
Publisher: name: University Of Tasmania
Year: 2023

description: Passive sampling is a useful method for contaminant analysis and monitoring, and of the techniques available the Diffusive Gradients in Thin Films (DGT) technique is particularly applicable for use in transition metal studies. However, analysis of the metal-accumulating DGT 'binding phase' is typically expensive and time consuming, which limits the technique's application. In order to improve on the cost and speed of analysis, and to allow in-field analysis, a colorimetric binding phase was developed. By employing metallochromic reagents adsorbed onto ion-exchange resins a colour change was obtained as a result of the binding of metal ions, with the degree of change being proportional to the quantity of complexed metal. This reagent-adsorbed resin was immobilised on adhesive paper labels to provide a robust, cheap and effective colorimetric binding phase. Quantification of metal loading on these binding phases was undertaken through use of UV-Vis reflectance or Computer Imaging Densitometry (CID), the latter employing a flat-bed scanner for improved ease of analysis. Analytically robust metal quantification was found to be achievable using these methods, with the CID method equivalent in performance to the reflectance method. The use of a variety of metallochromic reagents was explored, with different reagents noted to provide colorimetric responses for different metal ions. A typical detection limit, provided by Methylthymol Blue adsorbed to Dowex 1x8 resin, was 10 ng Cu(II) per cm\\(^{-2}\\) of disc area. Linear response was seen up to a stoichiometrically defined metal loading, typically providing a linear response from the detection limit to 2 ¬¨¬µg of Cu(II) per cm\\(^{-2}\\). Selectivity was reagent dependant, in particular Zincon was seen to provide a selective response to Cu(II) at neutral pHs and is a promising candidate for deployment of these colorimetric DGT binding phases.

description: In realizations of quantum computing, a two-level system (qubit) is often singled out of the many levels of an anharmonic oscillator. In these cases, simple qubit control fails on short time scales because of coupling to leakage levels. We provide an easy to implement analytic formula that inhibits this leakage from any single-control analog or pixelated pulse. It is based on adding a second control that is proportional to the time-derivative of the first. For realistic parameters of superconducting qubits, this strategy reduces the error by an order of magnitude relative to the state of the art, all based on smooth and feasible pulse shapes. These results show that even weak anharmonicity is sufficient and in general not a limiting factor for implementing quantum gates.

description: Polymer nanocomposites have improved mechanical, optical and thermal properties compared to traditional thermoplastics. To study the impact of grafted brush–matrix interactions on the mechanical properties of nanoparticle filled polymers, uniaxial tensile testing with digital image correlation (DIC) was done on polystyrene (PS) grafted SiO2 in low molecular weight (MW) (N ∼ P), N = degree of polymerization of grafted brush, P = degree of polymerization of matrix, and high MW (2N = P) matrices at different loadings. The low matrix MW composites had higher strength than high MW composites at high loading but lower strength than the pure matrix. The high matrix MW composites had higher toughness at low loadings. SEM images of fracture surfaces revealed particle debonding and plastic void growth in the high toughness samples. The results show that the P/N ratio of polymer grafted nanoparticle composites is important for controlling the mechanical properties of polymer nanocomposites.
title: Synthesis, Structure-Activity Relationship Study, and Mode of Action Study of 1,4-Naphthoquinone Based Anticancer and Antimicrobial Agents

description: Synthesizing bioactive small molecules by structural modification of 1,4-naphthoquinone was the primary goal of this research. Several bioactive compounds with anticancer, antifungal, and antibacterial activities were synthesized. All the synthetic protocols were optimized in such ways that do not require cumbersome purification.
First, a new protocol for the synthesis of NQM111 was developed. NQM111 is a highly potent anticancer agent developed in our laboratory, but the old protocol does not provide enough quantity for in vivo study. Therefore, a new safe and improved method was developed which provides enough quantity for in vivo study.
The second project involves the synthesis of 1,4-naphthoquinone conjugated with an aromatic group. These compounds are a highly potent anticancer agent with ~8-fold selectivity towards cancer cell lines than the non-cancer cell line. A mode of action study of this compound was identified, and it was observed that these compounds generate reactive oxygen species,which triggers apoptosis.
The final project involves the synthesis of 1,4-naphthoquinone based antifungal, and antibacterial compounds. These compounds are multi-cationic in nature with a hydrophobic tail. Six different analogs with varying hydrophobic tails were synthesized and tested for their antibacterial and antifungal activity. These compounds showed excellent activity against wide range of fungi including resistant strains.
Development of an implantable blood flow and pressure monitor for pulmonary hypertension : new finite element modelling based conductance catheter techniques for measuring blood flow
Creators: name: Locke, SE

description: Pulmonary hypertension patients could greatly benefit from use of an implantable blood flow and pressure monitor that can be used to derive pulmonary resistance. This thesis concentrates on the development of a suitable implantable sensor for measuring flow. Various methods for measuring flow are assessed. Conductance catheter techniques are proposed as some of the most promising, but suffer from limited accuracy. The main chapters of the thesis concentrate on the development of more accurate conductance catheter techniques. Realistic three-dimensional dynamic models of the heart, developed from MRI and tagged MRI scans, were used with finite element analysis to simulate the electric field arising from the conductance catheter in the heart. Results show that catheter movement and tissue impedance changes give non-negligible error using existing methods for calculating volume from impedance measurements. A new method for calculating volume from impedance measurements was developed that corrects for these and other errors. The new method finds the inverse mapping of a parameterised numerical model. It also allows use of additional data available from the conductance catheter technique, including data from different current source configurations and frequencies. The new technique was tested in a simplified model of the heart. Derivatives of the catheter measurements with respect to the model parameters were determined at one parameter configuration and formed into vectors. Derivative angles were then found between the vectors, providing a method for assessing the separability of the different model parameters. In addition they did not require creation of the inverse mapping. Two different types of techniques for creating the inverse mapping were tested. These were a new technique based on a distance metric and optimisation, and traditional artificial intelligence techniques. Even in the presence of no measurement error, limitations of traditional artificial intelligence techniques prevented successful application. The new technique performed to the order of accuracy of the numerical model on the same amount of data the traditional artificial intelligence techniques were trained on. The new technique was further developed to compensate for measurement error, and resulted in a further increase in accuracy. This thesis has developed and tested new conductance catheter methods, and has moved us a step closer to enabling practical development of an implantable blood flow and pressure monitor.

description: We present an experimental study of the power spectrum of current-driven magnetization oscillations in MgO tunnel junctions under low bias. We find the existence of narrow spectral lines, down to 8 MHz in width at a frequency of 10.7 GHz, for small applied fields with clear evidence of an auto-oscillation threshold. Micromagnetics simulations indicate that the excited mode corresponds to an edge mode of the synthetic antiferromagnet.

title: "Reasonably Bright Girls": Theorizing Women's Agency in Technological Systems of Power
Creators: name: Petersen, Emily January

description: A woman’s experience in the workplace is an inductive process into a technological, hierarchical, and often male-dominated system. This study examines how female practitioners in technical and professional communication confront the technological system of the workplace. I trace the forces that contribute to the hierarchy and power struggles women face, I present how they claim authority and agency within such hierarchical and technological systems, and I show how these experiences can lead to activism and advocacy.In addition, my findings suggest that some women leave the workplace altogether in favor of less structured and more innovative ways of communicating about technologies, particularly technologies and processes they find more applicable to their lives as women. The data from 39 interviews with female practitioners reveals that the traditional notion of the workplace is in crisis, and that women are asserting agency in order to disrupt the system and ensure a place for themselves within it.
