description: We study the transversal motion of paramagnetic particles on a uniaxial garnet film, exhibiting a longitudinal ratchet effect in the presence of an oscillating magnetic field. Without the field, the thermal diffusion coefficient obtained by video microscopy is $D_{0}\approx 3\times 10^{-4}$ $μm^2/s$. With the field, the transversal diffusion exhibits a giant enhancement by almost four decades and a pronounced maximum as a function of the driving frequency. We explain the experimental findings with a theoretical interpretation in terms of random disorder effects within the magnetic film.

Envisioning a higher education system for the 21st century : Cambodia
Creators: name: Phan, Sopheap
Publisher: name: University of British Columbia
Year: 2015

description: Higher education is essential for Cambodia’s human, social, cultural, and economic development. Yet, it is ineffective and inefficient. Improving higher education, especially making it more responsive to the needs for human resources, is one of the gravest and most urgent reforms Cambodia needs to undertake. This study aimed to explore options to help Cambodia improve in this area. To achieve this objective, the study incorporated the qualitative research methods of document review and stakeholder interviews as a means of collecting and analysing data. A document review of statistics, technical reports, policy papers, and academic literature sources obtained from both local and international institutions was conducted throughout the research project. During July and August 2014, semi-structured interviews with 18 Cambodian participants were conducted to obtain their perspectives about Cambodian higher education development and challenges. These participants were purposively selected from various backgrounds and included students, parents, faculty, university administrators, higher education officers/expert, employers, and non-governmental staff member. In keeping with the research purpose, three questions were deployed to guide the study: (a) What are the challenges facing higher education in Cambodia? (b) What lessons can Cambodia learn from policy and practice reforms in developing countries and how can these lessons inform higher education policy development in Cambodia? and (c) What do key stakeholders see as issues and directions for Cambodian higher education? Overall, the findings indicated that, despite rapid development and growth after the introduction of private higher education in the mid-1990s, Cambodia’s higher education subsector still faces many overarching challenges that need to be addressed to ensure greater effectiveness and efficiencies. This study points out those problems. Also, it suggests some key changes that higher education institutions and the Cambodian government need to make to correct the mismatch between higher education and labour market demand. The directions proposed in this study are expected to provide policymakers in Cambodia (and hopefully elsewhere) with a foundation for their future higher education policy discussions and debates.

description: Motivation. Modern methods of whole transcriptome sequencing accurately recover nucleotide sequences of RNA molecules present in cells and allow for determining their quantitative abundances. The coding potential of such molecules can be estimated using open reading frames (ORF) finding algorithms, implemented in a number of software packages. However, these algorithms show somewhat limited accuracy, are intended for single-molecule analysis and do not allow selecting proper ORFs in the case of long mRNAs containing multiple ORF candidates.
 Results. We developed a computational approach, corresponding machine learning model and a package, dedicated to automatic identification of the ORFs in large sets of human mRNA molecules. It is based on vectorization of nucleotide sequences into features, followed by classification using a random forest. The predictive model was validated on sets of human mRNA molecules from the NCBI RefSeq and Ensembl databases and demonstrated almost 95% accuracy in detecting true ORFs. The developed methods and pre-trained classification model were implemented in a powerful ORFhunteR computational tool that performs an automatic identification of true ORFs among a large set of human mRNA molecules.

description: Silicon undergoes a phase transition from the semiconducting diamond phase to the metallic beta-Sn phase under pressure. We use quantum Monte Carlo calculations to predict the transformation pressure and compare the results to density functional calculations employing the LDA, PBE, PW91, WC, AM05, PBEsol and HSE06 exchange-correlation functionals. Diffusion Monte Carlo predicts a transition pressure of 14.0 +- 1.0 GPa slightly above the experimentally observed transition pressure range of 11.3 to 12.6 GPa. The HSE06 hybrid functional predicts a transition pressure of 12.4 GPa in excellent agreement with experiments. Exchange-correlation functionals using the local-density approximation and generalized-gradient approximations result in transition pressures ranging from 3.5 to 10.0 GPa, well below the experimental values. The transition pressure is sensitive to stress anisotropy. Anisotropy in the stress along any of the cubic axes of the diamond phase of silicon lowers the equilibrium transition pressure and may explain the discrepancy between the various experimental values as well as the small overestimate of the quantum Monte Carlo transition pressure.

description: Pancreatic cancer is associated with a high mortality rate, and the prognosis is positively related to immune status. In this study, we constructed a prognostic signature from survival- and immune-related genes (IRGs) to guide treatment and assess prognosis of patients with pancreatic cancer. The transcriptomic data were obtained from The Cancer Genome Atlas (TCGA) database, and IRGs were extracted from the ImmPort database. Univariate and LASSO regression analysis were used to obtain survival-related IRGs. Finally, the prognostic signature was constructed using multivariate regression analysis. The laboratory experiments were conducted to verify the key IRG expression. Immune cells infiltration was analyzed using the CIBERSORT algorithm and TIMER database. Prognostic signature containing four IRGs (ADA2, TLR1, PTPN6, S100P) was constructed with good predictive performance; in particular, S100P played a significant role in the immune microenvironment, and tumorigenesis of pancreatic cancer. Moreover, we found that CD8+ T cell and activated CD4+ memory T cell tumor infiltration was lower in the high-risk group, while high-risk score correlated positively with higher tumor mutational burden, and the higher half inhibitory centration 50 of chemotherapeutic agents Docetaxel and Sunitinib. In summary, this study identified and constructed an immune-related prognostic signature that can predict overall survival, besides suggests that S100P was a novel immune-related biomarker. We hope that this signature will aid the identification of new biomarkers for the individualized immunotherapy of pancreatic cancer.

Diet analysis of Pacific harbour seals (Phoca vitulina richardsi) using high-throughput DNA sequencing
Creators: name: Thomas, Austen Clause
Publisher: name: University of British Columbia
Year: 2015

description: Harbour seals have long been perceived to compete with fisheries for economically valuable fish resources in the Pacific Northwest, but assessing the amounts of fish consumed by seals requires estimates of harbour seal diets. Unfortunately, traditional diet analysis techniques cannot provide the necessary information to estimate the species, life stage, and biomass of key prey (e.g. salmonids) consumed by seals. I therefore developed a new harbour seal diet analysis methodology, using scat DNA metabarcoding and prey hard-part analysis to create refined estimates of salmon in harbour seal diet. I also sought to understand the quantitative potential of DNA metabarcoding diet analysis (i.e. the relationship between prey biomass proportions and DNA sequence percentages produced by high-throughput amplicon sequencing of seal scat DNA). Analysis of faecal samples (scats) from captive harbour seals fed a constant diet indicated that a wide range of factors influence the numbers of prey sequences resulting from scat amplicon sequencing. These biases ranged from preferential amplification of certain prey species DNA, to sequence quality filtering—in addition to interactions between the various biases. I was able to apply correction factors derived from tissue mixtures of the species fed to captive seals that improved prey biomass estimates from DNA, and found that the lipid content of prey fish species perfectly predicted the magnitude of bias resulting from differential prey digestion. My results suggest that highly accurate pinniped prey biomass estimates can be attained by applying two stages of corrections to prey DNA sequence counts. However applying these corrections to the scats of wild seals is challenging, and requires a complete prey tissue mix library to create species-specific correction factors for all prey. While I established an approach that could be applied to wild seals, a thorough statistical evaluation and follow-up feeding studies are needed to determine if the additional effort is justified for population level diet estimates. Lastly, I developed a decision tree approach for merging salmon DNA and hardparts data from seal scats to determine the species and life stages of salmon consumed by seals in the Strait of Georgia, British Columbia.
I trusted myself to pick what works for me : the meaning and management of complementary and alternative medicine during pregnancy
Creators: name: Schmidt, Bethany
Publisher: name: University of British Columbia
Year: 2015

description: Pregnancy and childbirth are major life events for some women. These experiences hold great personal and social significance. In Western countries, the use of complementary and alternative medicine (CAM) among pregnant women is on the rise (Bakx, 1991; Eastwood, 2000; Tovey, Easthope, and Adams, 2003). There is little research into pregnant women’s decision-making when choosing CAM (Adams et al., 2009) or how they negotiate discordant discourses on pregnancy, health, and wellbeing. This thesis explores the experiences of pregnant women who access CAM while simultaneously embracing biomedical knowledge and expertise. This study utilized semi-structured interviews to explore pregnant women’s decisions to use CAM within the context of consumer-driven health care, rising neoliberalism, and the history of the medicalization of women’s bodies. Foucault’s theory of biopolitics is used as the theoretical framework for this project. The process of designing an individual prenatal health care regimen is complex and multi-faceted. The agency on the part of pregnant women to pick and choose the therapies that suit their own needs and preferences remains a potentially subversive act in the context of overarching medical dominance.
Locality and scheduling in the massively multithreaded era
Creators: name: Rogers, Timothy Glenn
Publisher: name: University of British Columbia
Year: 2015

description: Massively parallel processing devices, like Graphics Processing Units (GPUs), have the ability to accelerate highly parallel workloads in an energy-efficient manner. However, executing irregular or less tuned workloads poses performance and energy-efficiency challenges on contemporary GPUs. These inefficiencies come from two primary sources: ineffective management of locality and decreased functional unit utilization. To decrease these effects, GPU programmers are encouraged to restructure their code to fit the underlying hardware architecture which affects the portability of their code and complicates the GPU programming process. This dissertation proposes three novel GPU microarchitecture enhancements for mitigating both the locality and utilization problems on an important class of irregular GPU applications. The first mechanism, Cache-Conscious Warp Scheduling (CCWS), is an adaptive hardware mechanism that makes use of a novel locality detector to capture memory reference locality that is lost by other schedulers due to excessive contention for cache capacity. On cache-sensitive, irregular GPU workloads, CCWS provides a 63% speedup over previous scheduling techniques. This dissertation uses CCWS to demonstrate that improvements to the hardware thread scheduling policy in massively multithreaded systems offer a promising new design space to explore in locality management. The second mechanism, Divergence-Aware Warp Scheduling (DAWS), introduces a divergence-based cache footprint predictor to estimate how much L1 data cache capacity is needed to capture locality in loops. We demonstrate that the predictive, pre-emptive nature of DAWS can provide an additional 26% performance improvement over CCWS. This dissertation also demonstrates that DAWS can effectively shift the burden of locality management from software to hardware by increasing the performance of simpler and more portable code on the GPU. Finally, this dissertation details a Variable Warp-Size Architecture (VWS) which improves the performance of irregular applications by 35%. VWS improves irregular code by using a smaller warp size while maintaining the performance and energy-efficiency of regular code by ganging the execution of these smaller warps together in the warp scheduler.
Subtle Emergences

Publisher: name: University of British Columbia

description: We often understand the world around us by studying its parts. This approach, known as reductionism, has long dominated rational inquiry. The limitations of using this approach in isolation have started to become apparent as people have started to realize that complex systems, such as ecosystems, do not behave as a linear combination of parts. In many cases, the emergent behaviours of complex systems cannot be deduced empirically. I explore the role of experience and embodied inquiry as an alternative approach to studying complex systems. Through the proposal, production, installation, and exhibition of a complex, interactive art system, Subtle Emergences, I argue that experience of complexity is a valid and vital tool in our attempt to grapple with the uncertainty of complex systems. Ultimately, we need to use all available methods together, if we hope to be able to understand complexity.

description: We analyze the link between standardization and economic growth by systematically reviewing leading economics journals, leading economic growth researchers' articles, and economic growth-related books. We make the following observations: 1) No article has analyzed the link between standardization and economic growth in top5 economics journals between 1996 and 2018. 2) A representative sample of the leading researchers of economic growth has allocated little attention to the link between standardization and economic growth. 3) Typically, economic growth textbooks do not contain "standards" or "standardization" in their word indexes. These findings suggest that the economic growth theory has neglected the role of standardization.
Kinetic and deactivation studies of methane oxidation over palladium catalysts in the presence of water
Creators: name: Gholami Shahrestani, Rahman
Publisher: name: University of British Columbia
Year: 2015

description: Natural gas vehicles (NGVs) generate considerably fewer emissions of CO, NOx and CO₂ in comparison to conventional diesel and gasoline vehicles, although these benefits are mitigated by the presence of significant amounts of CH₄ in the exhaust. The relatively low temperature (423–823 K) and high concentrations of CO₂ and H₂O in the NGV exhaust gas make current catalytic converters inefficient for the removal of unburned CH₄. Although Pd is the most active metal for CH₄ oxidation, Pd catalysts deactivate after long time exposure to the NGV exhaust conditions. This thesis develops an understanding of the deactivation mechanisms of Pd supported catalysts following thermal treatments and examines the kinetics of CH₄ oxidation, accounting for the effect of H₂O. Hydrothermal aging (HTA) at high temperatures (673–973 K) is shown to significantly deactivate PdO/SiO₂ catalysts used for CH₄ oxidation. PdO occlusion by the SiO₂ support is responsible for catalyst deactivation at low HTA temperatures (673 K), whereas a combination of PdO sintering and PdO occlusion contributes to significant deactivation at high HTA temperatures (973 K). The stability of PdO catalysts during HTA is dependent upon the support. PdO/α-Al₂O₃ is found to have the highest catalyst stability during HTA at 973 K for up to 65 h and its high stability is attributed to a strong Pd-support interaction. Although PdO crystallites sinter and are occluded by the support during HTA, PdO occlusion only affects PdO/SiO₂ performance significantly. The deactivation of PdO/γ-Al₂O₃ and PdO/SnO₂ during HTA at 973 K is attributed to PdO sintering and a PdO → Pd⁰ transformation. The kinetics of CH₄ oxidation over a PdO/γ-Al₂O₃ catalyst is also reported. A power law model can accurately predict the observed temperature-programmed CH₄ oxidation data profiles measured for PdO/γ-Al₂O₃ at conversions < 40% when 0.1 v.% CH₄ with no H₂O or 0.5 v.% CH₄ with ≤ 2 v.% H₂O are present in the feed. At high H₂O concentration, model fit is improved with 0.1 v.% CH₄ in the feed but shows significant deviation with 0.5 v.% CH₄ in the feed.

description: The tumbling dynamics of individual polymers in semidilute solution is studied by large-scale non-equilibrium mesoscale hydrodynamic simulations. We find that the tumbling time is equal to the non-equilibrium relaxation time of the polymer end-to-end distance along the flow direction and strongly depends on concentration. In addition, the normalized tumbling frequency as well as the widths of the alignment distribution functions for a given concentration-dependent Weissenberg number exhibit a weak concentration dependence in the cross-over regime from a dilute to a semidilute solution. For semidilute solutions a universal behavior is obtained. This is a consequence of screening of hydrodynamic interactions at polymer concentrations exceeding the overlap concentration.

We investigate the role of optical birefringence on the stability of these solitons. In agreement with recent experimental observations, we show that birefringence-induced astigmatism can eventually destabilize these vortex solitons. However, for low and moderate birefringence, vortex solitons can propagate stably over experimentally relevant distances.

description: We have discovered an ultrasoft X-ray transient source, 2XMMi J184725.1-631724, which was detected serendipitously in two XMM-Newton observations in the direction of the center of the galaxy IC 4765-f01-1504 at a redshift of 0.0353. These two observations were separated by 211 days, with the 0.2-10 keV absorbed flux increasing by a factor of about 9. Their spectra are best described by a model dominated by a thermal disk or a single-temperature blackbody component (contributing >80% of the flux) plus a weak power-law component. The thermal emission has a temperature of a few tens of eV, and the weak power-law component has a photon index of ~3.5. Similar to the black hole X-ray binaries in the thermal state, our source exhibits an accretion disk whose luminosity appears to follow the $L\propto T^4$ relation. This would indicate that the black hole mass is about 10^5-10^6 M_sun using the best-fitting inner disk radius. Both XMM-Newton observations show variability of about 21% on timescales of hours, which can be explained as due to fast variations in the mass accretion rate. The source was not detected by ROSAT in an observation in 1992, indicating a variability factor of >64 over longer timescales. The source was not detected again in X-rays in a Swift observation in 2011 February, implying a flux decrease by a factor of >12 since the last XMM-Newton observation. The transient nature, in addition to the extreme softness of the X-ray spectra and the inactivity of the galaxy implied by the lack of strong optical emission lines, makes it a candidate tidal disruption event. If this is the case, the first XMM-Newton observation would have been in the rising phase, and the second one in the decay phase.

Sustainable seafood in an era of overfishing
Creators: name: Nakamura, Katrina
Publisher: name: University of British Columbia
Year: 2015

description: People derive benefits from the seafood trade including food security, work and profits. As trade increases worldwide, the impacts of seafood production increase and are known to include overfishing and labour abuses in distant source areas, including the developing countries that provide most of the world’s seafood. Over the past decade, as demand for sustainably certified wild-caught seafood has begun to increase, seafood buyers, sellers and NGOs have taken voluntary measures to encourage sustainable seafood production, but without knowledge of the effects. What kinds of effects result from voluntary industry measures for sustainable seafood? Do the effects improve the social and environmental impacts of seafood production? Drawing from quality assurance methods and sustainability theory, seven voluntary measures taken in the private sector between 2008 and 2014 were evaluated for their effects against ten qualitative attributes said by sustainable seafood scholars to be necessary conditions for stewardship of common pool natural resources. Results indicate that the seven measures led to new forms of industry self-regulation that help to control some input variables of overfishing and to some increased compliance across supply chains. New empirical information was produced by the measures to determine where change is needed to solve conflicts and to reduce risks where they occur in seafood production. Some measures made access to resources more secure for business. Others provide diagnostic tools to reduce risks for overfishing, illegal fishing and forced and trafficked labour in seafood supply chains. Overall the measures helped the private sector to see and understand what is happening in source fisheries and to agree on ways to fix unsustainable practices.

description: Quantum Monte Carlo approaches such as the diffusion Monte Carlo (DMC) method are among the most accurate many-body methods for extended systems. Their scaling makes them well suited for defect calculations in solids. We review the various approximations needed for DMC calculations of solids and the results of previous DMC calculations for point defects in solids. Finally, we present estimates of how approximations affect the accuracy of calculations for self-interstitial formation energies in silicon and predict DMC values of 4.4(1), 5.1(1) and 4.7(1) eV for the X, T and H interstitial defects, respectively, in a 16(+1)-atom supercell.
The relation of education for autonomy and education for morality : implications for debates over educational aims
Creators: name: Bigari, James
Publisher: name: University of British Columbia
Year: 2015

description: In this dissertation I analyze the relationship between education for autonomy and education for morality, and assess the implications of this analysis for debates between liberal, communitarian, and fundamentalist philosophies of education. A conceptual analysis of education based on R. S. Peters’ later work posits education as the expansion and deepening of awareness of those aspects of the human condition that are of particular relevance for a given socio-historical situation. In this sense, education can be conceptualized as the development of excellent perceivers of the human condition. I then posit nine fundamental awareness-promoting capacities whose development will be a necessary part of education: the five senses, critical thinking, empathy, imagination, memory, self-awareness, concentration, intuition, and language. Drawing upon an expanded account of Eamonn Callan’s conception of autonomy, I propose an integrative account of education for autonomy that includes social conditions, and educational and caregiving practices that facilitate autonomy. Drawing upon work in moral psychology, I conduct an analysis of the degree to which these elements of education for autonomy contribute to or hinder moral development. I conclude that education for autonomy and education for morality are mutually interdependent, and any overemphasis of one to the detriment of the other will be self-defeating. Finally, I argue that this analysis reveals the feasibility of liberal and communitarian philosophies of education that are balanced in their advocating of both morality and autonomy as educational aims, but reveals fundamentalist philosophies of education to be problematic insofar their stated educational aims are incompatible, and their methods partially self-defeating. Conceptual limitations of this study and areas in need of further research are discussed.

An XMM-Newton spectral survey of 12 micron selected galaxies. I. X-ray data

description: We present an X-ray spectral analysis of 126 galaxies of the 12 micron galaxy sample. We pay particular attention to Compton thick AGN with the help of new spectral fitting models that we have produced, which are based on Monte-Carlo simulations of X-ray radiative transfer, using both a spherical and torus geometry, and taking into account Compton scattering and Fe fluorescence. We use this data to show that with a torus geometry, unobscured sight lines can achieve a maximum EW of the Fe Kαline of ~150 eV, originally shown by Ghisellini, Haardt & Matt (1994). In order for this to be exceeded, the line of sight must be obscured with N_H>10^23 cm^-2, as we show for one case, NGC 3690. We also calculate flux suppression factors from the simulated data, the main conclusion from which is that for N_H>10^25 cm^-2, the X-ray flux is suppressed by a factor of >10 in all X-ray bands and at all redshifts, revealing the biases present against these extremely heavily obscured systems inherent in all X-ray surveys. Furthermore, we confirm previous results from Murphy & Yaqoob (2009) that show that the reflection fraction determined from slab geometries is underestimated with respect to toroidal geometries. For the 12 micron selected galaxies, we investigate the distribution of X-ray power-law indices, finding that the mean $=1.90_{-0.07}^{+0.05}$ and $σ_Γ= 0.31_{-0.05}^{+0.05}$) is consistent with previous works, and that the distribution of Γfor obscured and unobscured sources is consistent with the source populations being the same, in general support of unification schemes. We determine a Compton thick fraction for the X-ray AGN in our sample to be 18+/-5% which is higher than the hard X-ray (>10 keV) selected samples. Finally we find that the obscured fraction for our sample is a strong function of X-ray luminosity, peaking at L_X~10^42-43 ergs s^-1.

A camera-based approach to remote pointing interactions in the classroom
Creators: name: Escalona Gonzalez, Francisco
Publisher: name: University of British Columbia

description: Modern classrooms are brimming with technological resources, from sound systems and multiple large wall displays to the individual computers and cellphones of students. Leveraging this technology presents interesting opportunities in human-computer interaction to potentially create a richer experience that improves the effectiveness of classrooms both for lecturers and students. A key enabler of this experience is the ability for lecturers to manipulate objects on the screen by direct pointing, allowing them to be away from a computer for input. We designed and implemented a remote pointing technique that makes use of a web-camera and a pattern of shapes on the wall display to perform target tracking. A controlled study to evaluate performance and compare the camera-based technique to a traditional mouse for a target selection task in a classroom setting revealed that both devices have comparable error rates but that users are almost twice as fast with the mouse. The increased freedom of movement and immediacy of interaction provided by direct pointing makes the trade-off between speed and convenience reasonable. The technique does not require specialized hardware: the ubiquity of personal pocket cameras and computers makes target tracking with a camera a feasible future option for enabling direct pointing interactions on large wall displays in classroom settings.

description: Here we report chemical vapor deposition of graphene on gold surface at ambient pressure. We studied effects of the growth temperature, pressure and cooling process on the grown graphene layers. The Raman spectroscopy of the samples reveals the essential properties of the graphene grown on gold surface. In order to characterize the electrical properties of the grown graphene layers, we have transferred them on insulating substrates and fabricated field effect transistors. Owing to distinctive properties of gold, the ability to grow graphene layers on gold surface could open new applications of graphene in electrochemistry and spectroscopy.

EMTP-based load disaggregation at feeder levels
Creators: name: Shojae, Shima
Publisher: name: University of British Columbia

description: Power distribution networks play an important role in electricity grid. Distribution system components require becoming smarter and more automated for the sake of improving their reliability and increasing their operational efficiency. Smart meters are one of the powerful devices that achieved this goal. However, their data are of minimal use — grid or load information obtained from smart meters are shallowly analysed. This thesis takes advantage of the shortcoming by accurately calculating the load information using EMTP-based load disaggregation method. The approach is applicable to residential loads at small scale and feeders at large scale. In this thesis we first give our theoretical method for load disaggregation inspired by EMTP computational program. Then with simulation and experimental results, we demonstrate that our work outperforms past solutions by the following advantages: 1. EMTP-based load disaggregation is applicable at every point of interest, i.e., from distribution feeder down to the customer’s entry point. 2. Unlike other methods, our method employs both transient and steady state load properties. 3. Last but not least, our solution is capable of determining load’s electrical parameters. In this thesis we stress on three major eigen-loads: (1) motor, (2) resistive, and (3) purely inductive. Then we report how much of the load is made of each eigen-load. We exampled our method on a number of PSCAD simulation cases and a few real appliance measurements. Our results prove load disaggregation shall assist power system engineers in evaluating the power flow on accurate load observations.
