A comparison of agonistic behaviour between two populations of juvenile coho salmon (Oncorhynchus kisutch)
Creators: name: Rosenau, Marvin Leslie
Publisher: name: University of British Columbia
Year: 2010

description: Interpopulation variability in electrophoretically detectable isozyme frequencies, morphology, meristics and migratory behaviour has been demonstrated in many studies for salmonids and these character differences are known to often have an inherited basis. In this study, agonistic behaviours were compared in two British Columbia lower mainland populations of juvenile coho salmon and inherited differences were shown to occur. Using mirror image stimulation techniques, recently emerged laboratory incubated and reared coho juveniles from the study populations were tested for lateral display differences and the Hope Slough coho were found to have an higher activity level than the Nathan Creek fish in two brood years, 1979 and 1980. Additionally, coho of the 1980 experimental group were cross fertilized producing interpopulational "hybrids" and these fish were intermediate to the "pure" fish in lateral display behaviour activity levels. Recently emerged wild juvenile coho were, obtained and brought back to the laboratory and tested with the same mirror image stimulation techniques. Similar interpopulational differences in behaviour were found to occur. Laboratory reared fish were also compared in groups in stream tanks as well as in pairs in isolated aquaria. Hope Slough juvenile coho were found to be relatively more aggressive than Nathan Creek fish. It was felt that these observed differences have an adaptive basis in nature. Therefore, some physical and biological characteristics were measured in the two study watersheds. Potential differences in growth conditions and/or differing densities of predators were postulated as having potential selective effects on the behavioural repertoires of the juvenile coho in the study populations.

Out of hospital cardiac arrest in Saskatoon : an assessment of the emergency medical system
Creators: name: Medd, Lorna May
Publisher: name: University of British Columbia
Year: 2010

description: The question addressed in this thesis is should the City of Saskatoon, Saskatchewan develop an emergency medical system (EMS) specifically designed to deal with out-of-hospital cardiac arrest? In order to answer this question, a series of subsidiary questions must be dealt with, as follows: 1. Can an EMS provide real health gains in terms of decreased morbidity and mortality from cardiac arrest? 2. What are the components of an EMS that are required to achieve this decrease in morbidity and mortality? 3. Is the community in question typical for cardiac arrest in terms of sociodemographic, morbidity, and mortality patterns, or sufficiently different from population data in the published literature that the EMS will be required to accommodate the differences? 4. How important a cause of morbidity and mortality is cardiac arrest, and will it become a greater or a lesser problem in the next decade? 5. Is the establishment of such a service an effective way of reducing morbidity and mortality from cardiac arrest, or are there ways of dealing with cardiac arrest that will have more impact? The province of Saskatchewan and the City of Saskatoon are attempting to deal with these issues in order to develop long range plans for an effective and affordable ambulance service for both the province and the larger cities. The causes and extent of sudden cardiac death in Canada and in Saskatoon are described from reports in the existing scientific literature and local death registry data. The epidemiology of coronary heart disease (CHD) and the impact on mortality from CHD by an array of primary, secondary and tertiary preventive interventions are presented in order to provide a context from which the most appropriate approach for Saskatoon may be chosen. Highly developed EMS1s in North America are described from published reports. Their impact on mortality is analysed, with particular attention paid to recent developments which appear most promising for Saskatoon and area. Features of the system which is currently operating in Saskatoon are drawn from data in the annual reports of the Saskatoon and Area Ambulance Board from 1980 to 1983. Recommendations based on the compiled data are specific to Saskatoon and area and are related to the needs, existing services and structures, and available resources in that community.

description: We study the viscosity and thermodynamic properties of QGP at RHIC by employing the recently extracted equilibrium distribution functions from two hot QCD equations of state of $O(g^5)$ and $O(g^6\ln(1/g))$ respectively. After obtaining the temperature dependence of energy density, and entropy density, we focus our attention on the determination of shear viscosity for a rapidly expanding interacting plasma, as a function of temperature. We find that interactions significantly decrease the shear viscosity. They decrease the viscosity to entropy density ratio, $η/{\mathcal S}$ as well.

description: The demand for energy-efficient and high performance embedded systems drives the evolution of new hardware architectures, including concepts like approximate computing. This paper presents a novel reconfigurable embedded platform named "phoeniX", using the standard RISC-V ISA, maximizing energy efficiency while maintaining acceptable application-level accuracy. The platform enables the integration of approximate circuits at the core level with diverse structures, accuracies, and timings without requiring modifications to the core, particularly in the control logic. The platform introduces novel control features, allowing configurable trade-offs between accuracy and energy consumption based on specific application requirements. To evaluate the effectiveness of the platform, experiments were conducted on a set of applications, such as image processing and Dhrystone benchmark. The core with its original execution engine, occupies 0.024mm2 of area, with average power consumption of 4.23mW at 1.1V operating voltage, average energy-efficiency of 7.85pJ per operation at 620MHz frequency in 45nm CMOS technology. The configurable platform with a highly optimized 3-stage pipelined RV32I(E)M architecture, possesses a DMIPS/MHz of 1.89, and a CPI of 1.13, showcasing remarkable capabilities for an embedded processor.

description: A finite range density and momentum dependent effective interaction is used to calculate the density and temperature dependence of the symmetry energy coefficient Csym(rho,T) of infinite nuclear matter. This symmetry energy is then used in the local density approximation to evaluate the excitation energy dependence of the symmetry energy coefficient of finite nuclei in a microcanonical formulation that accounts for thermal and expansion effects. The results are in good harmony with the recently reported experimental data from energetic nucleus-nucleus collisions.

description: A Spartan random process (SRP) is used to estimate the correlation structure of time series and to predict (extrapolate) the data values. SRP's are motivated from statistical physics, and they can be viewed as Ginzburg-Landau models. The temporal correlations of the SRP are modeled in terms of `interactions' between the field values. Model parameter inference employs the computationally fast modified method of moments, which is based on matching sample energy moments with the respective stochastic constraints. The parameters thus inferred are then compared with those obtained by means of the maximum likelihood method. The performance of the Spartan predictor (SP) is investigated using real time series of the quarterly S&P 500 index. SP prediction errors are compared with those of the Kolmogorov-Wiener predictor. Two predictors, one of which explicit, are derived and used for extrapolation. The performance of the predictors is similarly evaluated.

description: A 33.6 ps LSB Time-to-Digital converter was designed in 130 nm BiCMOS technology. The core of the converter is a differential 9-stage ring oscillator, based on a multi-path architecture. A novel version of this design is proposed, along with an analytical model of linearity. The model allowed us to understand the source of the performance superiority (in terms of linearity) of our design and to predict further improvements. The oscillator is integrated in a event-by-event self-calibration system that allows avoiding any PLL-based synchronization. For this reason and for the compactness and simplicity of the architecture, the proposed TDC is suitable for applications in which a large number of converters and a massive parallelization are required such as High-Energy Physics and medical imaging detector systems. A test chip for the TDC has been fabricated and tested. The TDC shows a DNL$\leq$1.3 LSB, an INL$\leq$2 LSB and a single-shot precision of 19.5 ps (0.58 LSB). The chip dissipates a power of 5.4 mW overall.

description: We study the production of electroweak gauge bosons at high energies in the framework of kt-factorization QCD approach. Contributions from the valence quarks are calculated using the quark-gluon interaction and quark-antiquark annihilation QCD subprocesses. The total and differential cross sections (as a function of the transverse momentum and rapidity) are presented and the ratio of cross sections for W and Z boson production is investigated. The conservative error analysis is performed. In the numerical calculations two different sets of unintegrated gluon distributions in the proton are used: the one obtained from Ciafaloni-Catani-Fiorani-Marchesini evolution equation and the other from Kimber-Martin-Ryskin prescription. Theoretical results are compared with experimental data taken by the D0 and CDF collaborations at the Tevatron. We demonstrate the importance of the quark component in parton evolution in description of the experimental data. This component is very significant also at the LHC energies.

description: XMM-Newton observations of the accreting, pulsating white dwarf in the quiescent dwarf nova GW Librae were conducted to determine if the non-radial pulsations present in previous UV and optical data affect the X-ray emission. The non-radial pulsations are evident in the simultaneous Optical Monitor data but are not detected in X-ray with an upper limit on the pulsation amplitude of 0.092 mags. The best fits to the X-ray spectrum are with a low temperature diffuse gas model or a multi-temperature cooling flow model, with a strong OVIII line, similar to other short period dwarf novae, but with a lower temperature range than evident in normal short period dwarf novae. The lack of pulsations and the spectrum likely indicate that the boundary layer does not extend to the surface of the white dwarf.

Privacy on Social Networking Sites Among Canadian Teenagers

description: The widespread popularity of social networking sites (SNSs) among teenagers continually raises concerns over their safety among parents, educators, and policy makers. Although a teen’s use of such platforms plays a vital role in his or her social development, such online activities lead to a plethora of personal information being shared that increases vulnerability to privacy invasion and information misuse.

The employed monitoring, restriction and educational methods of privacy protection have been unsuccessful in encouraging teens to stay private on SNSs. While researchers have investigated online practices of teens, we lack a clear understanding of the rationales behind their safety and confidence on SNSs. Additionally, with the rapid emergence of new social networking applications each year and the ongoing evolution of educational school programs on privacy, a teen’s notion of privacy and online behaviours are constantly evolving. As a result, a thorough exploration of online interactions and thought processes of teens can help us better understand them and consequently communicate with them.

This thesis explores the perception of online privacy by Canadian teenagers (15-17 year olds) as well as their privacy-related concerns and behaviours on SNSs. To this end, semi- structured interviews were conducted with high school students (N = 20), and an online survey was completed by a more diverse pool of participants (N = 94).

Based on our results, we grounded a theory that highlights our participants’ broad definition of online privacy which directly relates to their online privacy concerns. These concerns shape their decision-making processes about information disclosure. Our theory highlights our participants’ frequently used rationales for feeling safe online, the variety of protective measures used to address their privacy concerns, and the factors that influence their choice of SNSs. Our findings can help parents and educators gain a better under- standing of a teen’s perception of online privacy and interactions on SNSs. Additionally, our findings can inform the creation of better suited policies, educational approaches, and parental supervision techniques for teens.

Determination of some phytoestrogens in alfalfa sprouts
Creators: name: Yada, Sylvia Ann (Duffek)
Publisher: name: University of British Columbia
Year: 2010

description: Alfalfa sprouts were grown under selected conditions in order to determine the effect of growth period, light duration, rinse volume and rinse frequency on the accumulation of phytoestrogens. The phytoestrogens were isolated from a crude methanol extract of alfalfa sprouts using ethyl ether. The residue remaining following ethyl ether evaporation was redissolved in methanol for high-performance liquid chromatography (HPLC). A method for HPLC was developed using an octadecylsilane reversed-phase column, UV detection at 254 nm and a gradient methanol/ water solvent system containing 1.0% acetic acid and 0.1 M ammonium acetate. Baseline resolution of the phytoestrogens daidzein, formonone-tin and coumestrol from the alfalfa sprout extracts was achieved with an elution time of 30 minutes. Total phytoestrogen content ranged from 1 to 22 ppm dry weight alfalfa (or less than 2 ppm fresh weight alfalfa) depending on the growth conditions employed. Alfalfa sprouts grown in the dark (0 h light) for the longer growth period (148 h) had significantly greater (P≤ 0.05) contents of daidzein, formononetin and coumestrol than those sprouts from other chosen treatment combinations. Although the contribution of phytoestrogens to the human diet from alfalfa sprouts would appear to be markedly higher than from other common vegetables, the physiological significance of such an intake has not yet been determined.
Morphological and anatomical variation of picea in southwestern British Columbia
Creators: name: Scagel, Robert Kevin
Publisher: name: University of British Columbia
Year: 2010

description: Relations between individual trees hypothesized to be representative of Picea enqelmannii and P. sitchensis and putative hybrids in southwestern British Columbia were examined using several morphological and anatomical variables measured on cones, needles, and twigs. 36 variables were selected that had an inter-individual variation that exceeded intra-individual variation. Such relative variation suggested that the variables selected were more genetically than developmentally variable. These variables were measured on 640 trees. Patterns of inter- and intra-individual variation of these variables were examined with multivariate analyses. Similar patterns of intra-individual variation with respect to position in the canopy were detected regardless of the age of the tree or the species, suggesting that intra-individual variation in Picea is not necessarily a function of the environment extrinsic to the individual. Further, the two hypothesized taxa were not especially different with respect to the pattern of intra-individual variation. In an inter-individual context, the intra-taxonomic variation was shown to be larger than inter-taxonomic variation. Inter-individual variation attributed to the hypothesized taxa was smaller than intra-population variation. Inter-taxonomic variation was only 25 percent larger than intra-individual variation. Further, the hypothesized taxonomic polarity of the data was not co-incident with the actual polarity of the data. What taxonomic structure emerged was evident only as the extremes of a continuum of variation over a large geographic area reflecting large environmental variation, suggesting that recognition of two taxa of Picea in southwestern British Columbia may not be appropriate or practically feasible. From the evidence available here, it is not possible to attribute the pattern of variation to hybridization followed by introgression or to the differentiation of a single, large polymorphic taxon. The pattern of inter-individual variation was only partially correlated with regional and local scales of geographic and environmental variation. Local patterns of variation were not co-incident in 16 separate geographic areas. The relation of the pattern of variation in nursery grown trees with respect to regional scales of geographic variation was not co-incident with the patterns of variation in naturally grown trees from the same area of origin. This variability of relations suggests that inter-individual variation is probably attributable to processes operating at an extremely local scale. Implications from these conclusions are presented and discussed with respect to the systematics of Picea and the utilization of Picea in forestry and tree improvement programmes.

description: Second harmonic generation (SHG) spectroscopy ubiquitously enables the investigation of surface chemistry, interfacial chemistry as well as symmetry properties in solids. Polarization-resolved SHG spectroscopy in the visible to infrared regime is regularly used to investigate electronic and magnetic orders through their angular anisotropies within the crystal structure. However, the increasing complexity of novel materials and emerging phenomena hamper the interpretation of experiments solely based on the investigation of hybridized valence states. Here, polarization-resolved SHG in the extreme ultraviolet (XUV-SHG) is demonstrated for the first time, enabling element-resolved angular anisotropy investigations. In non-centrosymmetric LiNbO$_3$, elemental contributions by lithium and niobium are clearly distinguished by energy dependent XUV-SHG measurements. This element-resolved and symmetry-sensitive experiment suggests that the displacement of Li ions in LiNbO$_3$, which is known to lead to ferroelectricity, is accompanied by distortions to the Nb ion environment that breaks the inversion symmetry of the NbO$_{6}$ octahedron as well. Our simulations show that the measured second harmonic spectrum is consistent with Li ion displacements from the centrosymmetric position by $\sim$0.5 Angstrom while the Nb-O bonds are elongated/contracted by displacements of the O atoms by $\sim$0.1 Angstrom. In addition, the polarization-resolved measurement of XUV-SHG shows excellent agreement with numerical predictions based on dipole-induced SHG commonly used in the optical wavelengths. This constitutes the first verification of the dipole-based SHG model in the XUV regime. The findings of this work pave the way for future angle and time-resolved XUV-SHG studies with elemental specificity in condensed matter systems.

description: This work aims at performing Functional Principal Components Analysis (FPCA) with Horvitz-Thompson estimators when the observations are curves collected with survey sampling techniques. One important motivation for this study is that FPCA is a dimension reduction tool which is the first step to develop model assisted approaches that can take auxiliary information into account. FPCA relies on the estimation of the eigenelements of the covariance operator which can be seen as nonlinear functionals. Adapting to our functional context the linearization technique based on the influence function developed by Deville (1999), we prove that these estimators are asymptotically design unbiased and consistent. Under mild assumptions, asymptotic variances are derived for the FPCA' estimators and consistent estimators of them are proposed. Our approach is illustrated with a simulation study and we check the good properties of the proposed estimators of the eigenelements as well as their variance estimators obtained with the linearization approach.

In the case of a Gaussian radial density profile, exact analytical eigen solutions are found in terms of the Kummer confluent hypergeometric functions. The mode is identified as a convective cell propagating in the poloidal and axial direction, having at the same time a standing wave structure in the radial direction.

description: Betweenness centrality is a metric that seeks to quantify a sense of the importance of a vertex in a network graph in terms of its "control" on the distribution of information along geodesic paths throughout that network. This quantity however does not capture how different vertices participate together in such control. In order to allow for the uncovering of finer details in this regard, we introduce here an extension of betweenness centrality to pairs of vertices, which we term co-betweenness, that provides the basis for quantifying various analogous pairwise notions of importance and control. More specifically, we motivate and define a precise notion of co-betweenness, we present an efficient algorithm for its computation, extending the algorithm of Brandes in a natural manner, and we illustrate the utilization of this co-betweenness on a handful of different communication networks. From these real-world examples, we show that the co-betweenness allows one to identify certain vertices which are not the most central vertices but which, nevertheless, act as important actors in the relaying and dispatching of information in the network.

description: In the Randall-Sundrum model where the radion is stabilized by a Goldberger-Wise (GW) potential there is a supercooled transition from a deconfined to a confined phase at temperatures orders of magnitude below the typical Standard Model critical temperature. When the Higgs is localized at the IR brane the electroweak phase transition is delayed and becomes a strong first-order one where the Universe expands by a few e-folds. This generates the possibility of having the out-of-equilibrium condition required by electroweak baryogenesis in the electroweak phase transition. We have studied numerically the region of the GW parameter space where the theory is consistent and the latter possibility is realized. We have found that in most of the parameter space the nucleation temperature is so low that sphalerons are totally inactive inside the bubbles. The condition for sphalerons to be inactive after reheating imposes an upper bound on the reheating temperature that is weaker for heavy Higgs bosons so that the out-of-equilibrium condition seems to favor heavy over light Higgses. The condition for sphalerons to be active outside the bubbles puts an upper bound on the number of e-folds at the phase transition, roughly consistent with the critical value required by low-scale inflation to solve the cosmological horizon problem.

description: Volumetric modeling and neural radiance field representations have revolutionized 3D face capture and photorealistic novel view synthesis. However, these methods often require hundreds of multi-view input images and are thus inapplicable to cases with less than a handful of inputs. We present a novel volumetric prior on human faces that allows for high-fidelity expressive face modeling from as few as three input views captured in the wild. Our key insight is that an implicit prior trained on synthetic data alone can generalize to extremely challenging real-world identities and expressions and render novel views with fine idiosyncratic details like wrinkles and eyelashes. We leverage a 3D Morphable Face Model to synthesize a large training set, rendering each identity with different expressions, hair, clothing, and other assets. We then train a conditional Neural Radiance Field prior on this synthetic dataset and, at inference time, fine-tune the model on a very sparse set of real images of a single subject. On average, the fine-tuning requires only three inputs to cross the synthetic-to-real domain gap. The resulting personalized 3D model reconstructs strong idiosyncratic facial expressions and outperforms the state-of-the-art in high-quality novel view synthesis of faces from sparse inputs in terms of perceptual and photo-metric quality.

description: In this paper we make further refinements to the duality proposed between N=1 SQCD and certain string (supergravity plus branes) backgrounds, working in the regime of comparable large number of colors and flavors. Using the string theory solutions, we predict different field theory observables and phenomena like Seiberg duality, gauge coupling and its running, the behavior of Wilson and 't Hooft loops, anomalous dimensions of the quark superfields, quartic superpotential coupling and its running, continuous and discrete anomaly matching. We also give evidence for the smooth interpolation between higgsed and confining vacua. We provide several matchings between field theory and string theory computations.

A study on the function of foam from the proctodeal gland of the male Japanese quail (Coturnix coturnix japonica) with respect to its effects on sperm competition
Creators: name: Hickman, Andrew Richard
Publisher: name: University of British Columbia
Year: 2010

description: The effect of foam from the male Japanese quail on sperm competition was investigated by comparing fertility and mating behaviour of foam-producing (sham-operated) and foamless (foam gland cauterized) males in two male / five female mating group situations. In vitro examinations of sperm behaviour in foam were also carried out. Over an eight-week experimental period, foam-producing males sired more than 90% of the progeny produced when in competition with a foamless male. Pens in which two foamless males were competing had significantly lowered fertility and hatchability of eggs, while pens with two foam-producing males had the highest fertility. Foamless males attempted and completed copulations as often or more often than foam-producing males and examinations of females post-copula revealed that sperm transfer was occurring during copulations by both types of males. Results indicate that foam allows a male to copulate less frequently and yet maintain good fertility levels. Foam significantly hindered the penetrating ability of quail sperm in thin albumin-filled capillary tubes (75 mm long x 1.2 inner diameter). On the other hand, foam significantly prolonged quail sperm motility. The behaviour of quail sperm when mixed with foam from the same or from a different male, was indistinguishable when examined on microscope slides at 400x magnification. I found that during copulation by quail, sperm and foam are mixed and deposited into the female's coprodeum, rather than in the oviduct as with most other birds examined. In conclusion, because the temporal pattern of egg laying in the Japanese quail (late in the day) precludes a peak in copulations at the optimum time for fertilization (within an hour post-oviposition), foam may aid a male's reproductive success by suspending and sustaining his sperm in the female's coprodeum, thus avoiding excessive loss of sperm via oviposition. These experiments also suggest a hypothesis about a role for foam in sperm competition: its physical presence fills space which may preclude normal foam and semen deposition by subsequent copulations and thus increase the chances of the foam/sperm mass from subsequent copulations being excreted by the female.

description: We compute the entropy reduction in feedback controlled systems due to the repeated operation of the controller. This was the lacking ingredient to establish the thermodynamics of these systems, and in particular of Maxwell's demons. We illustrate some of the consequences of our general results by deriving the maximum work that can be extracted from isothermal feedback controlled systems. As a case example, we finally study a simple system that performs an isothermal information-fueled particle pumping.

description: We consider general metric $f(R)$ theories of gravity by solving the field equations in the presence of a spherical static mass distribution by analytical perturbative means. Expanding the field equations systematically in $\cO(G)$, we solve the resulting set of equations and show that $f(R)$ theories which attempt to solve the dark energy problem very generally lead to $γ_{PPN}=1/2$ in the solar system. This excludes a large class of theories as possible explanations of dark energy. We also present the first order correction to $γ_{PPN}$ and show that it cannot have a significant effect.

description: Identifying the physiological processes in the central nervous system that underlie our conscious experiences has been at the forefront of cognitive neuroscience. While the principles of classical physics were long found to be unaccommodating for a causally effective consciousness, the inherent indeterminism of quantum physics, together with its characteristic dichotomy between quantum states and quantum observables, provides a fertile ground for the physical modeling of consciousness. Here, we utilize the Schrödinger equation, together with the Planck--Einstein relation between energy and frequency, in order to determine the appropriate quantum dynamical timescale of conscious processes. Furthermore, with the help of a simple two-qubit toy model we illustrate the importance of non-zero interaction Hamiltonian for the generation of quantum entanglement and manifestation of observable correlations between different measurement outcomes. Employing a quantitative measure of entanglement based on Schmidt decomposition, we show that quantum evolution governed only by internal Hamiltonians for the individual quantum subsystems preserves quantum coherence of separable initial quantum states, but eliminates the possibility of any interaction and quantum entanglement. The presence of non-zero interaction Hamiltonian, however, allows for decoherence of the individual quantum subsystems along with their mutual interaction and quantum entanglement. The presented results show that quantum coherence of individual subsystems cannot be used for cognitive binding because it is a physical mechanism that leads to separability and non-interaction. In contrast, quantum interactions with their associated decoherence of individual subsystems are instrumental for dynamical changes in the quantum entanglement of the composite quantum state vector and manifested correlations of different observable outcomes.
