description: This study inspects the influence of various effects and free parameters of the accretion disc and circumstellar material on the emerging light curve of eclipsing binary systems that have a circumstellar disc, by using the SHELLSPEC code. The results indicate that some of the parameters namely the temperature and inclination of the disc, spot, jet, stream and shell significantly affect on the emerging light curve while some other parameters namely the exponent of the power-law behavior of the density of the disc, microturbulence, inner and outer radius of the disc don't noticeably affect on the emerging light curve. An application to the Algol-type eclipsing binary system AV Del and an accretion disc model for the system using the SHELLSPEC code is included.

description: Molecular motors are found throughout the cells of the human body, and have many different and important roles. These micro-machines move along filament tracks, and have the ability to convert chemical energy into mechanical work that powers cellular motility. Different types of motors are characterized by different duty-ratios, which is the fraction of time that a motor is attached to its filament. In the case of myosin II - a non-processive molecular machine with a low duty ratio - cooperativity between several motors is essential to induce motion along its actin filament track. In this work we use statistical mechanical tools to calculate the duty ratio of cooperative molecular motors. The model suggests that the effective duty ratio of non-processive motors that work in cooperation is lower than the duty ratio of the individual motors. The origin of this effect is the elastic tension that develops in the filament which is relieved when motors detach from the track.

Meshing and rendering of patient-specific deformation models with application to needle insertion simulation
Creators: name: Goksel, Orcun
Publisher: name: University of British Columbia
Year: 2010

description: Tissue deformation is common during many medical interventions. An accurate simulation of these procedures necessitates accounting for tissue displacements by modeling tissue deformation and medical tool interaction. In minimally-invasive procedures, due to lack of visibility, physicians rely on haptic feedback and medical imaging to assess the immediate anatomical configuration and relative medical tool position. These procedures are often difficult to learn and therefore extensive training becomes essential. Computerized training systems offer an alternative to cadavers and training on patients. To accurately model the tissue deformation, most such systems require a mesh representation of the anatomy. To replicate the medical imaging feedback offered during procedures, a realistic image simulation approach is also needed. In this thesis, a novel energy-based meshing technique taking medical images and producing desirable meshes for the finite element method is introduced. This method employs an image-based discretization energy combined with a geometry-based element quality energy. The former promotes each mesh element to cover similar intensity image regions, while the latter ensures the element suitability for finite element simulation. A method that can mimic realistic B-mode ultrasound images under deformation is also presented in this thesis. This method first maps the pixels of an image from a deformed mesh configuration back to the nominal configuration, and then interpolates them in a B-mode voxel volume reconstructed a priori. Needle insertion is involved in several medical procedures. These percutaneous procedures will benefit significantly from advances in simulating needle-tissue interaction, for which a 3D model is proposed in this thesis. Simulating needle flexibility is achieved fast and accurately using a novel approach employing torsional springs. The needle insertion simulation with haptic feedback is presented for a training scenario for prostate brachytherapy, where simulated ultrasound images coupled with deformation are also displayed. A scheme to generate patient models for this system is also devised using both the conventional meshing techniques in the literature and the proposed variational meshing method.

description: In the context of kernel density estimation, we give a characterization of the kernels for which the parametric mean integrated squared error rate $n^{-1}$ may be obtained, where $n$ is the sample size. Also, for the cases where this rate is attainable, we give an asymptotic bandwidth choice that makes the kernel estimator consistent in mean integrated squared error at that rate and a numerical example showing the superior performance of the superkernel estimator when the bandwidth is properly chosen.

description: Sustainable practices are seen as one of the solutions to redress the negative impact of agriculture's growing intensification. Despite efforts by many governments, the adoption rate of sustainable practices amongst farmers is still low. One of the causes is policymakers’ insufficient knowledge of farming-system diversity. In order to account for such diversity, this paper proposes classifying farming systems, including new elements such as the sustainability level of agricultural practices and market channel traits, in combination with socio-economic and farm characteristics. We apply a farming typology approach, using vegetable production in Chile as our case study. We developed the typology using multivariate analysis techniques including principal component analysis (PCA) and hierarchical clustering (CA). We collected data using surveys (n = 352) in the central region of Chile. The results reveal five farming-system types: (1) Large dual farming, (2) ecological farming, (3) traditional farming, (4) conventional small-scale farming, and (5) conventional medium-scale farming. The five farming system types provide insights on the different agricultural practices used and their different starting points in terms of their transition towards more sustainable agriculture practices. We also propose possible policies based on these farming-system types that can be useful for policymakers to promote sustainable practices.

description: In an earlier study, we reported on the excitation of large-scale vortices in Cartesian hydrodynamical convection models subject to rapid enough rotation. In that study, the conditions of the onset of the instability were investigated in terms of the Reynolds (Re) and Coriolis (Co) numbers in models located at the stellar North pole. In this study, we extend our investigation to varying domain sizes, increasing stratification and place the box at different latitudes. The effect of the increasing box size is to increase the sizes of the generated structures, so that the principal vortex always fills roughly half of the computational domain. The instability becomes stronger in the sense that the temperature anomaly and change in the radial velocity are observed to be enhanced. The model with the smallest box size is found to be stable against the instability, suggesting that a sufficient scale separation between the convective eddies and the scale of the domain is required for the instability to work. The instability can be seen upto the co-latitude of 30 degrees, above which value the flow becomes dominated by other types of mean flows. The instability can also be seen in a model with larger stratification. Unlike the weakly stratified cases, the temperature anomaly caused by the vortex structures is seen to depend on depth.

description: The existence of the $J^p=1/2^+$ narrow resonance predicted by the chiral soliton model has been investigated by utilizing the new kaon photoproduction data. For this purpose, we have constructed two phenomenological models, which are able to describe kaon photoproduction from threshold up to W=1730 MeV. By varying the resonance mass, width, and $KΛ$ branching ratio in this energy range we found that the most convincing mass of this resonance is 1650 MeV. Using this result we estimate the masses of other antidecuplet family members.

In MDMO-PPV:PC61BM we find a strongly field dependent polaron pair dissociation which can be attributed to geminate recombination in the device. Our findings are in good agreement with field dependent photoluminescence measurements published before, supporting a scenario of polaron pair dissociation via an intermediate charge transfer (CT) state. In contrast, polaron pair dissociation in P3HT:PC61BM shows only a very weak field dependence, indicating an almost field independent polaron pair dissociation or a direct photogeneration. Furthermore, we found Langevin recombination for MDMO-PPV:PC61BM and strongly reduced Langevin recombination for P3HT:PC61BM.

Computational prediction of regulatory element combinations and transcription factor cooperativity
Creators: name: Fulton, Debra Louise
Publisher: name: University of British Columbia
Year: 2011

description: Cellular identity and function is determined, in part, by the subset of genes transcribed. Gene transcription regulation is directed by a subgroup of proteins called transcription factors (TF), which can interact directly or indirectly with DNA to promote transcription initiation. In multi-cellular eukaryotes, gene expression often derives from synergistic and/or antagonistic interplay of multiple TFs with coordinate activity in response to physiological, developmental, and environmental stimuli. Sequence-specific interactions of TFs with DNA occur at TF binding sites (TFBS). Such TFBS can be predicted based on previously observed target DNA sequence specificity of a TF. Experimental studies have confirmed that proximally situated TFBS are often associated with synergistic interactions of multiple proteins that lead to cooperative regulation. The identification of clustered TFBS combinations (often called cis-regulatory modules) in a set of co-expressed genes can implicate regulatory roles for homologous groups of TFs that may contribute to co-regulation of a gene cohort. The identification of the specific TFs that interact with TFBS motifs is an important step in deciphering mechanisms of co-regulation. My thesis research addressed these challenges, firstly, through the design and development of a Combination Site Analysis (CSA) algorithm to identify over-representation of combinations of TFBS in co-expressed genes and, secondly, the assembly of a comprehensive wiki-based catalog of human-mouse TFs (TFCat) using literature curation and homolog prediction approaches. These applications were incorporated within a new promoter sequence analyses procedure for the identification of TFs that may be acting cooperatively to co-regulate expression of myelin-associated genes during myelin production in the CNS. Dysregulation of gene expression is frequently implicated in human pathologies and development of approaches that identify the molecular components of transcriptional regulatory systems is an important step towards the elucidation of molecular mechanisms for the design of therapeutic interventions.

description: Spectroscopic observations of 63 HII regions in six spiral galaxies (NGC 628, NGC 783, NGC 2336, NGC 6217, NGC 7331, and NGC 7678) were carried out with the 6-meter telescope (BTA) of Russian Special Astrophysical Observatory with the Spectral Camera attached to the focal reducer SCORPIO in the multislit mode with a dispersion of 2.1A/pixel and a spectral resolution of 10A. These observations were used to estimate the oxygen and nitrogen abundances and the electron temperatures in HII regions through the recent variant of the strong line method (NS calibration). The parameters of the radial distribution (the extrapolated central intercept value and the gradient) of the oxygen and nitrogen abundances in the disks of spiral galaxies NGC 628, NGC 783, NGC 2336, NGC 7331, and NGC 7678 have been determined. The abundances in the NGC 783, NGC 2336, NGC 6217, and NGC 7678 are measured for the first time. Galaxies from our sample follow well the general trend in the luminosity - central metallicity diagram for spiral and irregular galaxies.

description: In the realm of deep learning-based recommendation systems, the increasing computational demands, driven by the growing number of users and items, pose a significant challenge to practical deployment. This challenge is primarily twofold: reducing the model size while effectively learning user and item representations for efficient recommendations. Despite considerable advancements in model compression and architecture search, prevalent approaches face notable constraints. These include substantial additional computational costs from pre-training/re-training in model compression and an extensive search space in architecture design. Additionally, managing complexity and adhering to memory constraints is problematic, especially in scenarios with strict time or space limitations. Addressing these issues, this paper introduces a novel learning paradigm, Dynamic Sparse Learning (DSL), tailored for recommendation models. DSL innovatively trains a lightweight sparse model from scratch, periodically evaluating and dynamically adjusting each weight's significance and the model's sparsity distribution during the training. This approach ensures a consistent and minimal parameter budget throughout the full learning lifecycle, paving the way for "end-to-end" efficiency from training to inference. Our extensive experimental results underline DSL's effectiveness, significantly reducing training and inference costs while delivering comparable recommendation performance.

description: For Riemannian manifolds there are several examples which are isospectral but not isometric, see e.g. J. Milnor [Proc. Nat. Acad. Sci. USA 51 (1964), 542]; in the present paper, we investigate pairs of domains in ${\mathbb R}^2$ which are isospectral but not congruent. All known such counter examples to M. Kac's famous question can be constructed by a certain tiling method ("transplantability") using special linear operator groups which act 2-transitively on certain associated modules. In this paper we prove that if any operator group acts 2-transitively on the associated module, no new counter examples can occur. In fact, the main result is a corollary of a result on Schreier coset graphs of 2-transitive groups.

We investigated the phase structure in this regime by computing the Higgs vacuum expectation value, and by exploring the finite-size scaling behaviour of the susceptibility corresponding to the magnetisation. Our preliminary results indicate the existence of a second-order phase transition when the Yukawa coupling becomes large enough, at which the Higgs vacuum expectation value vanishes and the susceptibility diverges.

description: Excavations were undertaken near the town of Lillooet in 1970 and 1971 to collect information about the prehistoric cultures of the area. Attention was focused upon the last 2,500 to 3,000 years of regional prehistory, a period poorly understood at that time. Six sites were selected for intensive excavation. These sites are described along with the artifacts, features, and burials which were uncovered. Age estimates are offered for most components based primarily on radiocarbon and obsidian hydration dating. The Nesikep Tradition is defined as the basic integrative or archaeological unit for Plateau prehistory. It is divided into an earlier microlithic period dating from about 5000 to 800 B.C., and a later non-microlithic period from 800 B.C. to A.D. 1858. A chronology of archaeological units is proposed for the later Nesikep Tradition consisting of four sequential phases: Nicola Phase, 800 B.C.-A.D. 200: Lillooet Phase, A.D. 200-800: Kamloops Phase, A.D. 800-1750: and Protohistoric Phase, A.D. 1750-1858. The temporal and spatial distribution as well as the trait inventory of each phase is discussed. A reconstruction of the later Nesikep Tradition culture(s) on the mid Fraser is offered. Paleo-environmental, archaeological, and ethno-linguistic information are integrated to arrive at an overall developmental scheme for the evolution of culture on the Interior Plateau of British Columbia and the Lillooet excavations are placed within the context of Plateau culture history.

description: This thesis represents an attempt at elucidating the temporal and spatial interrelationships between barrenland cultures, climates and caribou herds. Its core is in the form of a case study, that of the pre­historic interaction of the human hunting bands, climatic effects and caribou herd distributions in the Canadian barrenlands during the Arctic Small Tool tradition occupation after 1500 B.C. Following initial des­criptions of barrenland geography, biology, geology, climatology and ethnology, site locations resulting from the hunter and prey relationship are ex-plored. Basic to this relationship and site locations are two primary suppositions. They are: (1) caribou herds are discrete, their separateness b.?se.d upon environment and behavior; and (2) the hunting soci.eties who prey upori. the caribou tend to be discrete due to their alignment with discrete herds. Three corollaries follow the suppositions: (1) band movements and human communication are usually confined to herd migration corridors and forage areas; (2) differing cultural patterns develop in the hunting societies within herd areas; and (3) artifacts are more homogeneous within herding areas and more heterogeneous between herding areas, primarily due to restricted lateral movement and communi­cation. Because of their distribution, quantity, chronology and excel­lent diagnostic qualities, artifacts of the Arctic Small Tool tradition were used in testing the corollaries. The corollaries and suppositions comprise the discrete band/discrete herd relationship.

description: Archaeological field research at Point Pelee in extreme southern Ontario has revealed a unique sequence of prehistoric aboriginal occupations comprising three major multi-component sites spanning nearly a thousand years. This sequence has been subdivided into four temporal periods, commencing in the 6th century A.D. and terminating about the 15th century A.D. This time frame of nearly a thousand years spans the major duration of aboriginal use of Point Pelee. Absolute temporal control is supported by ten radiocarbon determinations from four Point Pelee sites. Most, if not all sites investigated were seasonally occupied and represent a range of settlement types from encampments of perhaps single family size and brief duration, to larger settlements of multiseasonal occupation supporting possibly band-size groups. Direct archaeological evidence for subsistence strategies chiefly emphasizes the exploitation of the abundant natural resources associated with the Point Pelee marsh and forest habitats and, to a much less degree, the resources of Lake Erie. Inferences drawn from Point Pelee botanical and paleobotanical data, specific site locations and ethnographic analogies, further support the use and overwhelming potential of indigenous wild plant resources. These various lines of evidence point to a high probability that the pursuit of specific wild plants may have been the prime motivation for prehistoric utilization of Point Pelee. There is archaeological evidence for the introduction of corn to Point Pelee by the 10th-11th century A.O., however it is believed that this corn was not grown locally. Archaeological evidence for cultural continuity or an indigenous developing tradition(s) is not characteristic of the Point Pelee cultural components. Instead, at least three and perhaps as many as five distinct cultural groups are represented in this sequence. What appears to emerge is a composite of cultural vignettes derived from a number of cultural traditions and in some instances having their roots in distantly separated geographic areas of the Great Lakes region.

According to Rutherford backscattering the Mn ions are mainly at the Ga-substitutional positions, and they are homogeneously distributed according to depth-resolved Auger-electron spectroscopy and secondary-ion mass-spectroscopy measurements. A random Mn distribution is indicated by transmission electron microscopy, no Mn-rich clusters are present for optimized growth conditions. A linear increase of the c-lattice parameter with increasing Mn concentration is found using x-ray diffraction. The ferromagnetic behavior is confirmed by superconducting quantum-interference measurements showing saturation magnetizations of up to 150 emu/cm^3.

description: Diese Arbeit stellt die erste Anwendung der räumlichen Probenahmetechnik zur Untersuchung von Flüßigphasenreaktionen dar, in diesem Fall des (HP-PO)-Prozesses. Zur Untersuchung der Reaktion unter industriellen Bedingungen wurde ein kompakter Profilreaktor verwendet. Zur Simulation der experimentellen Daten wurden zwei Modelle aus der wissenschaftlichen Literatur und ein im Rahmen dieser Arbeit vorgeschlagenes neues Modell verwendet. Ein Reaktor im Pilotmaßstab wurde implementiert, um die Leistung eines mit Katalysatorextrudaten gefüllten Bettes mit der eines Bettes aus Additiv Hergestellten Offenen Zellstrukturen zu vergleichen.
description: This work constitutes the first application of the spatial sampling technique to study a liquid phase reactions. The reaction under study is the (HP-PO) process. A compact profile reactor was used to study the reaction under industrial conditions. Two models from the scientific literature and a new model proposed within this work were used to simulate the experimental data. A pilot scale reactor with a internal diameter comparable to those in technical scale (HP-PO) reactors was implemented to compare the performance of a bed packed with catalyst extrudates against a bed constituted by additively manufactured open cell structures.

description: In a recent letter [D. Poletti et al., EPL 93, 37008 (2011)] a model of attractive spinless fermions on the honeycomb lattice at half filling has been studied by mean-field theory, where distinct homogenous phases at rather large attraction strength $V>3.36$, separated by (topological) phase transitions, have been predicted. In this comment we argue that without additional interactions the ground states in these phases are not stable against phase separation. We determine the onset of phase separation at half filling $V_{ps}\approx 1.7$ by means of infinite projected entangled-pair states (iPEPS) and exact diagonalization.

Surface evolution during gallium arsenide homoepitaxy with molecular beam epitaxy
Creators: name: Whitwick, Michael Brian
Publisher: name: University of British Columbia
Year: 2010

description: GaAs grown with MBE is the basis for many useful optoelectric devices. Measurements are presented of the smoothing of patterned and randomly roughened GaAs surfaces during homoepitaxy over a large range of Ga flux, substrate temperatures, arsenic fluxes, and Bi surfactant. The bulk of these measurements were taken by in-situ elastic light scattering or ex-situ AFM. These measurements provide experimental support for a non-linear continuum growth model that has been derived analytically from basic atomic level phenomena that occur in epitaxial film growth. During epitaxial growth the smoothing is observed to change in nature as the surface amplitude decreases. One of the regimes of smoothing is associated with the linear smoothing coefficients from the physically based non-linear continuum growth equation. The temperature and growth rate dependence of the smoothing coefficients are presented and found to be in good agreement with predictions from the continuum growth model. A key parameter in the continuum growth equation, the density of atomic steps, is measured independently using AFM. The step density, which agrees with theoretical predictions, is used to compute smoothing coefficients and is shown to be in agreement with the light scattering measurements. Complex shapes are observed for epitaxial growth on patterned GaAs substrates. Two characteristic surface morphologies were observed. The first is characterized by downward V-shaped cusps and rounded mounds caused by non-linear smoothing. The second morphology is similar, however the symmetry of the surface structure was inverted. This surface morphology has not been previously observed in GaAs. Step edge attachment was found to be the driving mechanism that produced both of these morphologies. Bismuth is observed to act as a surfactant in GaAs homoepitaxy. While Bi assisted growth is found to decrease the overall surface roughness, it is also found to alter the characteristics of the surface morphology. Notably, roughness at low spatial frequency was increased with the addition of Bi, while at high spatial frequency roughness was decreased. Significant changes to the shape evolution of patterned substrate are also observed when Bi is added to GaAs epitaxial growth.

description: We report a Raman scattering investigation of columnar BiFeO3-CoFe2O4 (BFO-CFO) epitaxial thin film nanostructures, where BFO pillars are embedded in a CFO matrix. The feasibility of a strain analysis is illustrated through an investigation of two nanostructures with different BFO-CFO ratios. We show that the CFO matrix presents the same strain state in both nanostructures, while the strain state of the BFO pillars depends on the BFO/CFO ratio with an increasing tensile strain along the out-of-plane direction with decreasing BFO content. Our results demonstrate that Raman scattering allows monitoring strain states in complex 3D multiferroic pillar/matrix composites.

description: The nature of EuroCanadian-Athapaskan interaction is examined in terms of settlement/subsistence behavior for the period 1778- 1900 in the Mackenzie Basin, N.W.T. The fur trade system is isolated intentionally as the primary impetus for nineteenth century Athapaskan adaptive adjustments. The stage for the problem under examination is set through a summary of the environmental and cultural contexts, including both a reconstruction of the aboriginal baseline and a developmental sequence of fur trading facilities in the Mackenzie Basin. The archaeology of nineteenth century EuroCanadian trade is then discussed in an effort to determine the factors affecting the location, distribution and maintenance of the trading establishments. This inquiry into EuroCanadian adaptation is further integrated with an examination of Athapaskan adjustments to ecological, cultural, and historical factors in the nineteenth century. This analysis focuses on 4 aspects of Athapaskan spacing behavior: dispersion, nucleation, mobility, and immobility. The result is a general interpretation of Athapaskan accommodation to the EuroCanadian trade and settlement system , specific to no particular tribal grouping. The essence of this reconstruction is the continuity exhibited between the pre-contact and nineteenth century subsistence/settlement pattern. Additional topics impinging upon this study are discussed in their appropriate context, including differential trade goods acceptance, food and fur overexploitation, pre-adaptation to the fur trade and so forth. There is an attempt to summarize some of these and other related issues in the final chapter.
