description: A sensor network consisting of small circuits that can be attached to physical equipment in a classroom environment was designed, manufactured, programmed, and tested. Each sensor measures human interaction with the equipment to which it is attached based on motion and reports the data wirelessly to a central Hub computer. All sensor operation is autonomous and requires no direct user-input. The sensors optionally and automatically pair with users through an associated user-worn sensor. The sensor network operates continuously over a long period of time with zero maintenance or operator intervention. The intention of this system is to collect data in a classroom to identify what equipment students use regularly. With this information, educators can make informed decisions about the impact that various resources have. To prove the functionality of the technology developed, a study was done at a fitness center where the sensors were attached to exercise machines. This was a comparable environment to a classroom as it involves consistent human-equipment interaction and was more readily accessible for this research due to ethics involving young students in research along with access restrictions due to COVID-19. The work carefully details the hardware and firmware development of the sensors as they are intended to be commercial-grade yet low cost for mass production. Thirty-five Equipment Sensors and fifteen User Sensors were fabricated and installed in the fitness facility for a two-week period and produced over 30,000 data points. Using redundant sensors on each equipment enabled comparison of the technical performance without having to directly involve gym participants. This gave the benefit of an authentic testing environment where participants would not change their behavior due to the study. The sensor data was used to assess the sensor’s technical performance. The Equipment Sensors provided reliable indication of equipment usage. The User Sensor portion of the study was limited as participation was voluntary and only passively advertised. Recommendations are provided on how to improve the sensor network and use it for future educational research in the classroom.

description: This project utilized the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database to explore preoperative patient variables as predictors of adverse postoperative respiratory occurrences (APRO) in thoracic surgery patients. These APROs include pulmonary embolism, pneumonia, unplanned intubation, and failure to wean. APROs are a significant problem in patients undergoing thoracic surgery. APROs can result in prolonged lengths of stay, poor long-term and short-term outcomes, and increased healthcare costs for patients and healthcare organizations. Conditional logistic regression explored which preoperative patient variables significantly influenced the odds of observing the APROs. Current Procedural Terminology (CPT) codes were used to match 722 thoracic surgery cases to a control case based on age +/- five years. Each APRO model contained five preoperative patient variables: sex, body mass index (BMI), serum creatinine, serum albumin, and hematocrit. These variables were chosen based on a review of recent literature and data available within the NSQIP database. Preoperative serum albumin was found to be significantly associated with all four APROs, and preoperative hematocrit was found to be significantly associated with three of four APROs (pulmonary embolism, unplanned intubation, and failure to wean). Findings from this project emphasize the need to optimize preoperative serum albumin, serum hematocrit, and serum creatinine at or near normal levels to decrease the odds of observing APROs after thoracic surgery. The authors of this project recommend the creation of checklists or risk assessment tools to preoperatively evaluate patients' risk for developing an APRO after thoracic surgery.

description: We report observations of 16 candidate polar ring galaxies (PRGs) identified by the Galaxy Zoo project in the Sloan Digital Sky Survey (SDSS) database. Deep images of five galaxies are available in the SDSS Stripe82 database, while to reach similar depth we observed the remaining galaxies with the 1.8-m Vatican Advanced Technology Telescope. We derive integrated magnitudes and u-r colours for the host and ring components and show continuum-subtracted Hα+[NII] images for seven objects. We present a basic morphological and environmental analysis of the galaxies and discuss their properties in comparison with other types of early-type galaxies. Follow-up photometric and spectroscopic observations will allow a kinematic confirmation of the nature of these systems and a more detailed analysis of their stellar populations.

Reducing variabilities in the mixer inflow concentration
Creators: name: Soltanzadeh, Ali
Publisher: name: University of British Columbia
Year: 2012

description: The thesis focuses on mixing fluids, and it has three main parts. The first part investigates mixing in agitated pulp chests. A new model for identifying the performance of mixing in the pulp chest is developed. This newly developed model simplifies the previous pulp chest model and successfully describes non-ideal flow behavior, including channeling and dead-zones which occurs in the agitated pulp chests. The model is verified through experimental data obtained in a laboratory-scale agitated pulp chest. In the second part of the thesis, a novel method for identifying residence time (the average time that it takes for material to exit the mixer) from input and output data is developed. The main benefit of this new method is that it does not require that an individual have prior knowledge of the process to evaluate the mixing inside the flow system. The same idea is used to estimate the higher moments of linear time invariant transfer functions from a batch of input and output data. The ability to estimate higher moments of a transfer function enables one to reconstruct the original transfer function without having knowledge of its structure. This opens new possibilities in non-parametric system identification and residence-time theory. It is also shown how a bound on the delay of all pole transfer functions can be found using the first and second moments. In the third part of the thesis, a new class of mixers is designed. These mixers do not have agitators, yet they are as effective as stirred tanks in reducing fluctuations in their inlet stream. However, they are only effective for reducing the concentration fluctuations in the flow direction (axial mixing). This design splits the fluid into different channels and recombines these streams to achieve mixing. These mixers are especially useful in microfluidic applications where there is a physical limitation in using agitators for mixing; therefore, in the final section of the thesis, a mixer is designed and its geometry is calculated for microfluidic purposes. Moreover, the effectiveness of the mixer in reducing inlet concentration fluctuations is shown through computational fluid dynamic simulations (CFD).

description: We report magnetic and spectroscopic observations and modeling of the Of?p star HD 148937 within the context of the MiMeS LP at the CFHT. Thirty-two high signal-to-noise ratio circularly polarised (Stokes V) spectra and 13 unpolarised (Stokes I) spectra of HD 148937 were acquired in 2009 and 2010. A definite detection of a Stokes V Zeeman signature is obtained in the grand mean of all observations (in both LSD mean profiles and individual spectral lines). The longitudinal magnetic field inferred from the Stokes V LSD profiles is consistently negative, in contrast to the essentially zero field strength measured from the diagnostic null profiles. A period search of equivalent width measurements confirms the previously-reported 7.03 d variability period. The variation of equivalent widths is not strictly periodic: we present evidence for evolution of the amount or distribution of circumstellar plasma. Interpreting the 7.03 d period as the stellar rotational period within the context of the ORM, we have phased the equivalent widths and longitudinal field measurements. The longitudinal field measurements show a weak sinusoidal variation of constant sign, with extrema out of phase with the Hα variation by about 0.25 cycles. The inferred magnetic configuration confirms the suggestion of Nazé et al (2010), who proposed that the weaker variability of HD 148937 as compared to other members of this class is a consequence of the stellar geometry. Based on the derived magnetic properties and published wind characteristics, we find a wind magnetic confinement parameter η\ast \simeq 20 and rotation parameter W = 0.12, supporting a picture in which the Halpha emission and other line variability have their origin in an oblique, rigidly rotating magnetospheric structure resulting from a magnetically channeled wind.

Geochemistry of Mud Gas Hydrocarbons and Flowback Waters for Assessment of Reservoir Characterization Techniques in the Montney Formation, Western Canada

description: This thesis investigates the use of flowback water analysis and mud gas isotope logging techniques to understand the stable isotope characteristics of the Montney Formation, an unconventional reservoir in northwestern Alberta and northeastern British Columbia, Canada. To produce valuable hydrocarbons from the Montney Formation, multi-lateral, stacked horizontal wells are drilled into various zones in the formation and the rock is hydraulically fractured to release the hydrocarbons from the tight pores. Following well drilling and fracturing operators use various techniques to assess the reach of the fractures. Ideally, the fractures are concentrated in the zones of interest and do not extend to overlying or underlying zones. The aim of this research is to assess isotope analysis techniques that are used for reservoir and fracture assessment. Isotopic and chemical analysis of flowback water samples were used to focus on the processes that occur in the formation after fracturing fluid is introduced during completions. Conservative tracers, including hydrogen and oxygen isotope ratios, and a mass balance mixing equation showed that the flowback water that was recovered from the Upper and Middle Montney zones was mostly formation water, while the Lower Montney evolved from fracturing fluid to formation water over the sampling period. The use of flowback water isotope analysis is useful to distinguish processes that control end- member water mixing in the Upper, Middle, and Lower zones of the Montney Formation and can be employed to assess the success of an induced fracturing program. IsoTube and IsoJar sampling systems are utilized to collect gas samples for isotope analysis as a well is drilled. The second section of the thesis assessed the sampling systems ability to preserve carbon isotope ratios samples that were collected as a horizontal well was drilled in the Montney Formation and as an adjacent vertical well was drilled through the Montney Formation. Produced gas samples from the Montney formation was used as a proxy for the expected results of the sampling systems. This research found that the IsoTube better preserves the carbon isotope signature of methane. The comparison of IsoJar and IsoTube samples over the depth of the vertical well highlights the relatively greater permeability in the Upper Montney zone. Neither the IsoJar or IsoTube sampling system preserved the gas composition for gas dryness and butane ratio assessment and are not recommended to be used for gas maturity analysis.
Improving Quantum Query Complexity of Boolean Matrix Multiplication Using Graph Collision

description: The quantum query complexity of Boolean matrix multiplication is typically studied as a function of the matrix dimension, n, as well as the number of 1s in the output, \ell. We prove an upper bound of O (n\sqrt{\ell}) for all values of \ell. This is an improvement over previous algorithms for all values of \ell. On the other hand, we show that for any \eps < 1 and any \ell <= \eps n^2, there is an Ω(n\sqrt{\ell}) lower bound for this problem, showing that our algorithm is essentially tight. We first reduce Boolean matrix multiplication to several instances of graph collision. We then provide an algorithm that takes advantage of the fact that the underlying graph in all of our instances is very dense to find all graph collisions efficiently.

description: We study the contextuality of a three-level quantum system using classical conditional entropy of measurement outcomes. First, we analytically construct the minimal configuration of measurements required to reveal contextuality. Next, an entropic contextual inequality is formulated, analogous to the entropic Bell inequalities derived by Braunstein and Caves in [Phys. Rev. Lett. {\bf 61}, 662 (1988)], that must be satisfied by all non-contextual theories. We find optimal measurements for violation of this inequality. The approach is easily extendable to higher dimensional quantum systems and more measurements. Our theoretical findings can be verified in the laboratory with current technology.

We show that the resultant equation suggests a novel ansatz for the functional form to be used in Grad moment method, which turns out to give the same expressions for the transport coefficients as those given in the Chapman-Enskog theory as well as the novel expressions for the relaxation times and lenghts allowing natural physical interpretaion.

Parent-Child Reminiscing in the Context of Procedural and Postsurgical Pediatric Pain

subject: memory for pain

subject: Psychology--Clinical

description: Objective. Children experience pain often and remember it long after painful experiences are over. Up to 25% of children remember past pain in a negatively-biased way (i.e., recalling higher levels of pain as compared to the initial pain reports) and are at risk of experiencing higher levels of pain in the future. Pain memories are malleable and can be reframed through conversations. Recent evidence demonstrated that the way parents reminisce about past pain with their children influenced how children remembered their past pain. Yet, no interventions have used parental reminiscing to change children’s memories for pain. The present dissertation aimed to develop a parent-led memory-reframing intervention that harnesses parent-child reminiscing about past pain and to examine the intervention’s efficacy to change children’s memories for pain. Methods. Three randomized controlled trials investigated whether parents can be taught to reminisce about past pain optimally to, in turn, change children’s memories for pain to be more accurate/positively-biased (i.e., recalling lower levels of pain compared to the initial reports). Additionally, the dissertation examined whether optimal parent-child reminiscing would result in lower levels of future needle pain. Parental beliefs regarding reminiscing about past pain were investigated to optimize the intervention and increase parental motivation to engage in reminiscing about past pain. Results. The parent-led memory-reframing intervention resulted in young children remembering their past post-surgical, but not needle, pain in a more accurate/positively-biased way. The intervention also changed parental reminiscing style to include optimal strategies for reframing past painful experiences. Parents rated the intervention to be feasible and highly acceptable in the context of post-surgical and needle pain. Results also demonstrated that some parental beliefs regarding reminiscing about past painful experiences may be a barrier that prevents parents from engaging in reminiscing about past pain. Conclusions. This dissertation developed and examined the efficacy of a parent-led memory-reframing intervention, a new avenue in pediatric pain management that targets children’s pain memories. The intervention was efficacious in changing how children remember their past post-surgical pain. The preliminary results warrant future large-scale trials to further examine the intervention’s potential to change children’s pain and health trajectories.

description: Immigrant and refugee women in Canada bear a disproportionate burden of HIV and HIV risk, and simultaneously experience a greater risk of gender-based violence (GBV), including interpersonal, community, and structural violence. The observed increase in multiple forms of GBV during the recent COVID-19 pandemic underscores the urgent need for research-informed progressive policies, practices, and community services to support this population. Understanding the impact of systemic racism and sexism within the context of immigrant and refugee women’s dual experiences of HIV/HIV-risk and GBV (HIV/GBV) is necessary to effectively develop comprehensive strategies that can challenge structural barriers and promote equity, social inclusion, and psycho-social well-being. This project sought to understand: • How systemic racism and sexism impact immigrant and refugee women’s dual experiences of HIV/GBV. • What policies, programs, or services, or lack there-of, support or create barriers for immigrant and refugee women experiencing HIV/GBV and what changes are required.

description: The heat conduction behavior of one dimensional momentum conserving lattice systems with asymmetric interparticle interactions is numerically investigated. It is found that with certain degree of interaction asymmetry, the heat conductivity measured in nonequilibrium stationary states converges in the thermodynamical limit, in clear contrast to the well accepted viewpoint that Fourier's law is generally violated in low dimensional momentum conserving systems. It suggests in nonequilibrium stationary states the mass gradient resulted from the asymmetric interactions may provide an additional phonon scattering mechanism other than that due to the nonlinear interactions.

description: Escherichia coli is a gram-negative bacterium commonly found in the human and animal gastrointestinal tract. Antibiotic resistance in E. coli is a significant concern in human and veterinary medicine, as it can lead to treatment challenges and transmission to other bacteria [3]. Antibiotic-free beef cattle certifications have been implemented to address antimicrobial resistance concerns in the food chain [7]. Objectives: To define the range of existing research in the area, individualize research gaps and suggest areas important for future research studies about Antimicrobial Resistance in Escherichia coli of Antibiotic-free and Conventionally Raised Beef Cattle from North America. Methods: This scoping review has been designed following the JBI Reviewer’s Manual and the PRISMA ScR guidelines for scoping reviews. The search question was constructed using the PICO framework. We will search the literature for peer-reviewed articles using the following databases: CAB Abstracts, BIOSIS Previews, Environmental Complete, the Web of Science’s Science Citation Index and Emerging Sources Citation Index. The grey literature search will include a search of ProQuest Dissertations and the websites of relevant government departments, agencies, and industry groups. Two independent reviewers will screen the articles at the title, abstract, and full-text levels.
Tidal disruption rate of stars by spinning supermassive black holes

description: A supermassive black hole can disrupt a star when its tidal field exceeds the star's self-gravity, and can directly capture stars that cross its event horizon. For black holes with mass M > 10^7 solar masses, tidal disruption of main-sequence stars occurs close enough to the event horizon that a Newtonian treatment of the tidal field is no longer valid. The fraction of stars that are directly captured is also no longer negligible. We calculate generically oriented stellar orbits in the Kerr metric, and evaluate the relativistic tidal tensor at pericenter for those stars not directly captured by the black hole. We combine this relativistic analysis with previous calculations of how these orbits are populated to determine tidal-disruption rates for spinning black holes. We find, consistent with previous results, that black-hole spin increases the upper limit on the mass of a black hole capable of tidally disrupting solar-like stars to ~7 x 10^8 solar masses. More quantitatively, we find that direct stellar capture reduces tidal-disruption rates by a factor 2/3 (1/10) at M = 10^7 (10^8) solar masses. The strong dependence of tidal-disruption rates on black-hole spin for M > 10^8 solar masses implies that future surveys like LSST that discover thousands of tidal disruption events can constrain supermassive black-hole spin demographics.

We find that the local density of states decreases in the regions where the bound states are localized. Dependence of bound-state energies on the asymptotic twist of the nanotubes is determined. We also show that each of the constructed unextended first order matrix systems possesses a proper nonlinear hidden supersymmetric structure with a nontrivial grading operator.

Developing a Novel Care Pathway for Symptoms of Agitation or Aggression in Persons Living with Dementia in Long-Term Care: A Multi-Methods Implementation Research Study
Creators: name: Wong, Britney
Publisher: name: Graduate Studies
Year: 2023
Subjects: subject: Education--Health
subject: Education--Sciences

description: Background: Agitation and/or aggression are common among persons living with dementia (PLWD) in LTC, and together pose a significant burden to residents and their caregivers. Current treatment practices for agitation and/or aggression are highly variable among PLWD in LTC. There is a need to develop a more effective approach to treatment and to explore the barriers and facilitators to providing care for agitation and/or aggression among PLWD in LTC. Objectives: The first objective was to develop an evidence-informed clinical care pathway co-designed with stakeholders, to improve care for agitation and/or aggression among PLWD in LTC. The second objective was to identify barriers and facilitators to agitation and/or aggression care across the spectrum of care. Methods: Objective 1 used a modified Delphi panel to develop the clinical care pathway. Objective 2 used semi-structured interviews with key stakeholders to identify the barriers and facilitators to care. Framework Analysis was used to map identified barriers and facilitators to key behavioral domains of the Theoretical Domains Framework. Results: Crucial pathway features included using an interdisciplinary care team approach across the spectrum of care and featuring a broad range of non-pharmacological interventions. Several statements in our pathway did not reach agreement and require a third round of the Delphi. Perceived barriers for agitation and/or aggression care included a lack of validated tools to detect agitation and/or aggression, inconsistent training practices, and a limited number of available non-pharmacological interventions. Key facilitators were using an interdisciplinary care team and having trained healthcare providers to administer non-pharmacological interventions. Conclusions: Our study advances the state of evidence for agitation and/or aggression care among PLWD in LTC. Our efforts will inform future implementation research strategies working to improve the delivery and management of care. With more effective care approaches, the quality of life of PLWD in LTC will also improve.
Astrometric confirmation of young low-mass binaries and multiple systems in the Chamaeleon star-forming regions

description: The star-forming regions in Chamaeleon are one of the nearest (distance ~165 pc) and youngest (age ~2 Myrs) conglomerates of recently formed stars and the ideal target for population studies of star formation. We investigate a total of 16 Cha targets, which have been suggested, but not confirmed as binaries or multiple systems in previous literature. We used the adaptive optics instrument Naos-Conica (NACO) at the Very Large Telescope Unit Telescope 4 of the Paranal Observatory, at 2-5 different epochs, in order to obtain relative and absolute astrometric measurements, as well as differential photometry in the J, H, and K band. On the basis of known proper motions and these observations, we analyse the astrometric results in our "Proper Motion Diagram" (PMD: angular separation / position angle versus time), to eliminate possible (non-moving) background stars, establish co-moving binaries and multiples, and search for curvature as indications for orbital motion. All previously suggested close components are co-moving and no background stars are found. The angular separations range between 0.07 and 9 arcseconds, corresponding to projected distances between the components of 6-845 AU. Thirteen stars are at least binaries and the remaining three (RX J0919.4-7738, RX J0952.7-7933, VW Cha) are confirmed high-order multiple systems with up to four components. In 13 cases, we found significant slopes in the PMDs, which are compatible with orbital motion whose periods range from 60 to 550 years. However, in only four cases there are indications of a curved orbit, the ultimate proof of a gravitational bond. Massive primary components appear to avoid the simultaneous formation of equal-mass secondary components. (abridged)

description: In this work, two machine learning (ML)-based structures for joint detection-channel estimation in OFDM systems are proposed and extensively characterized. Both ML architectures, namely Deep Neural Network (DNN) and Extreme Learning Machine (ELM), are developed {to provide improved data detection performance} and compared with the conventional matched filter (MF) detector equipped with the minimum mean square error (MMSE) and least square (LS) channel estimators. The bit-error-rate (BER) performance vs. computational complexity trade-off is analyzed, demonstrating the superiority of the proposed DNN-OFDM and ELM-OFDM detectors methodologies.

description: The adaptive and innate immunity are the two branches of the immune system our body uses to defend against invading microbes. After each encounter with a pathogen, the adaptive immune system develops a memory to prevent an infection with the same microbe. This ability to remember has recently also been shown in the innate immune system and was termed “trained immunity”, describing the ability to generate a stronger response towards a broad range of pathogens despite infection with just a single pathogen. The lung is an organ directly exposed to the microbes in the outside world, making it a likely site for immune cells to develop trained immunity. The predominant innate immune cells that reside in the lungs are the alveolar macrophages. These cells encounter countless pathogens every day and therefore are a likely cell in which to study trained immunity. Our lab recently figured out how to watch the macrophages crawl inside the lungs of living animals and this study examined how these macrophages behaved under different conditions (Neupane et al, 2020). However, these macrophages only live for a few months, so cells from the bone marrow constantly replace the macrophages, meaning that there are always two types of macrophages present in the lung. However, without an effective labelling tool, it was previously impossible to distinguish between the two macrophage populations, making their differences in behavior and function unknown. This study utilized a unique model to look at the two different macrophages and visualize these cells inside a living mouse to look for behavioural similarities and differences. Our findings determined the behavioral and functional similarities of these macrophages at homeostasis, their responses against the influenza virus, and provided support for both populations to be trained against influenza.
Implications of barriers to trade for exports of cultural goods and services

description: This dissertation contains three studies. Chapter 2 studies the effect of product quality on foreign entry using data on U.S. movie exports and direct and revealed measures of movie quality. In the model, fixed costs of entry mean only the more appealing movies will find it profitable to enter each country. Empirically, a one-standard-deviation increase in quality increases the probability of entry by 25-50%. Movies in culturally-laden genres are less likely to enter foreign markets and their probability of entry is more sensitive to quality. I exploit differences in the propensity to import different genre types to estimate a measure of cultural distance between countries. The cultural distance measure enters a gravity equation of merchandise trade significantly. Chapter 3 investigates the international diffusion of a new product. Products traditionally enter foreign markets sequentially. This paper proposes that part of the explanation is that firms want to learn about their products’ appeal before incurring the fixed costs of entry. Each successive release serves to update the firm’s expectations for future performance---and thus their decision to enter more markets. On a sample of U.S. movies, I find that a one-standard-deviation increase in the update, based on the previous round’s box-office "surprise", is associated with a 25% increase in the probability of entry to a typical potential destination in the current round. Chapter 4 investigates Canada's interprovincial and international trade in services. While modern technology has allowed for long-distance service provision, regulatory non-tariff barriers may constitute substantial hurdles for further trade liberalization. This chapter describes three exercises contributing to the analysis of Canadian service trade. Using a theoretically-motivated framework, I estimate provincial and national border effects, and track the effect over time that distance has had on international trade.
