description: We derive a theoretical model which describes Bose-Einstein condensation in an open driven-dissipative system. It includes external pumping of a thermal reservoir, finite life time of the condensed particles and energy relaxation. The coupling between the reservoir and the condensate is described with semi-classical Boltzmann rates. This results in a dissipative term in the Gross-Pitaevskii equation for the condensate, which is proportional to the energy of the elementary excitations of the system. We analyse the main properties of a condensate described by this hybrid Boltzmann Gross-Pitaevskii model, namely, dispersion of the elementary excitations, bogolon distribution function, first order coherence, dynamic and energetic stability, drag force created by a disorder potential. We find that the dispersion of the elementary excitations of a condensed state fulfils the Landau criterion of superfluidity. The condensate is dynamically and energetically stable as longs it moves at a velocity smaller than the speed of excitations. First order spatial coherence of the condensate is found to decay exponentially in 1D and with a power law in 2D, similarly with the case of conservative systems. The coherence lengths are found to be longer due to the finite life time of the condensate excitations. We compare these properties with the ones of a condensate described by the popular "diffusive" models in which the dissipative term is proportional to the local condensate density. In the latter, the dispersion of excitations is diffusive which as soon as the condensate is put into motion implies finite mechanical friction and can lead to an energetic instability.

description: For the sake of completeness, it was felt that a brief resume' of x-ray scattering theory as it affects the alignment procedure of a two crystal spectrometer would be beneficial.

X-ray diffraction from a single crystal slab.

W. L. Bragg (1912) tried the experiment of reflecting a beam of x-rays from the cleavage surface of a crystal and found on the photo-graphic plate a spot at the angle of reflection. He then replaced the photo graphic plate with an ionization chamber which he mounted so that it could be rotated about the axis upon which the reflecting crystal is mounted. He then rotated the reflecting crystal with respect to the incoming x-ray beam and plotted the ionization as a function of the reflecting angle. It was found that at certain angles the ionization current would reach a sharp maximum.

description: We report the observation of macroscopic field-free orientation, i.e. more than 73 % of CO molecules pointing in the same direction. This is achieved through an all-optical scheme operating at high particle densities ($>10^{17}$cm$^{-3}$) that combines a one-color ($ω$) and a two-color ($ω+ 2ω$) non-resonant femtosecond laser pulses. We show that the achieved orientation solely relies on the hyperpolarizability interaction as opposed to an ionization-depletion mechanism thus opening a wide range of applications. The achieved strong orientation enables us to reveal the molecular-frame anisotropies of the photorecombination amplitudes and phases caused by a shape resonance. The resonance appears as a local maximum in the even-harmonic emission around 28~eV. In contrast, the odd-harmonic emission is suppressed in this spectral region through the combined effects of an asymmetric photorecombination phase and a sub-cycle Stark effect, generic for polar molecules, that we experimentally identify.

ADVANCED MACHINE LEARNING EMPOWERING MICROWAVE SENSORS WITH GENERATIVE/PREDICTIVE CAPABILITIES
Creators: Kazemi, Nazli
Publisher: name: University of Alberta Library
Year: 2023

This dissertation, addressing the critical shortage of microwave planar sensors, embarks on a journey to advance noncontact sensing applications, with a particular emphasis on the application of machine learning techniques to address existing problems. It pioneers the introduction of a unique planar reflective sensor, employing complementary split ring resonators (CSRRs) as the primary sensing element, complemented by an additional loss-compensating negative resistance. Experimental results validate that this innovative design substantially amplifies the sensor's resolution without any detriment to sensitivity.

The thesis further unveils a novel design that utilizes coupled CSRRs, resulting in a sensor with heightened sensitivity. The sensor response in passive mode undergoes processing using CycleGAN, a machine learning algorithm typically harnessed for image-to-image translation. This groundbreaking application of machine learning effectively transmutes low-quality factor sensor profiles in the passive domain into their high-quality factor counterparts in the active domain. The resolution achieved by this CycleGAN-enhanced response rivals that of an active sensor, marking a significant leap in the resolution of passive sensors. This is a clear demonstration of how machine learning can be used to address the limitations of traditional sensor designs.

In the biomedical sensing arena, the thesis emphasizes the paramount importance of continuous glucose monitoring systems that obviate the need for invasive finger pricking, thereby ameliorating the comfort and lifestyle of diabetic patients. It advocates for a compact planar resonator-based sensor for noncontact glucose sensing, delivering real-time response and a strong linear correlation between sensor readings and blood glucose levels. The integration of the Long Short Term Memory (LSTM) algorithm, another machine learning technique, enables the prediction of glucose level fluctuations in both non-diabetic and diabetic patients. This facilitates early interventions in case of abnormal glucose trends and aids in identifying sensor anomalies. This is another example of how machine learning can be used to address real-world problems, in this case, improving the management of diabetes.

This research makes a monumental contribution to the field of microwave planar sensors by bolstering their robustness and resolution using machine learning algorithms of CycleGAN and LSTM. This paves the way for an expansion of potential applications in material characterization and biomedical analysis. The insights extracted from this thesis are instrumental in propelling the development of advanced sensor technologies, with a focus on crafting miniaturized devices. The central role of machine learning in these advancements cannot be overstated.

description: We study the gravitational clustering of spherically symmetric overdensities and the statistics of the resulting dark matter halos in the "symmetron model", in which a new long range force is mediated by a $Z_2$ symmetric scalar field. Depending on the initial radius of the overdensity, we identify two distinct regimes: for small initial radii the symmetron mediated force affects the spherical collapse at all redshifts; for initial radii larger than some critical size this force vanishes before collapse because of the symmetron screening mechanism. In both cases overdensities collapse earlier than in the $Λ$CDM and statistically tend to form more massive dark matter halos. Regarding the halo-mass function of these objects, we observe order one departures from standard $Λ$CDM predictions. The formalism developed here can be easily applied to other models where fifth-forces participate to the dynamics of the gravitational collapse.

description: Quantitative and realistic computer simulations of mass transfer associated with CO2 disposal in subsurface aquifers is a challenging endeavor. This article has proposed a novel and efficient multiscale modeling framework, and has examined its potential to study the pen- etrative mass transfer in a CO2 plume that migrates in an aquifer. Nu- merical simulations indicate that the migration of the injected CO2 enhances the vorticity generation, and the dissolution of CO2 has a strong effect on the natural convection mass transfer. The vorticity decays with the increase of the porosity. The time scale of the vertical migration of a CO2 plume is strongly dependent on the rate of CO2 dissolution. Comparisons confirm the near optimal performance of the proposed multiscale model. These primary results with an idealized computational model of the CO2 migration in an aquifer brings the potential of the proposed multiscale model to the field of heat and mass transfer in the geoscience.

Investigating the process of implementation of Inquiry-Based Learning in a University- Certificated Professional Development Program for EFL  In-Service Teachers in Egypt
Creators: Khalil, Lobna
Publisher: name: University of Alberta Library
Year: 2023

The current interpretive qualitative study explores the process of implementation of inquiry-based learning (IBL) in English as a Foreign Language (EFL) teachers’ certificated professional development programs at a higher education institution (HEI) in Egypt. The victories and barriers seen in the process of implementation are articulated through the perceptions of junior high in-service student teachers, their HEI instructors, and the HEI administrators. The design of the semi-structured interviews emerged from a literature review about IBL and reports from the Egyptian government’s mandates on the quality of professional development curricula. Through the lens of the theory of social constructivism, the study explores how using IBL in professional development programs might enrich an inquiry stance and critical thinking among student teachers. Moreover, study results might help professional development instructors and administrators bridge the gap between the theoretical knowledge exchanged in the program and the practices of inquiry-based approaches to learning.
A holistic optimization framework for integrating PV systems into building façades
Creators: Bakmohammadi, Parnian
Publisher: name: University of Alberta Library
Year: 2023

In recent years, the growing concern over fossil fuel supply insecurity and its negative environmental impacts has led researchers to focus on advancing renewable energy technologies. Buildings, which account for a significant portion of global energy consumption, offer great potential for incorporating renewable energy applications. Solar energy, particularly through the installation of PV panels on building façades, is regarded as a promising resource. However, the full potential of PV systems in buildings has not always been maximized, highlighting the need for collaborative efforts to develop practical and optimized designs for PV integration.

This study presents a comprehensive framework that considers energy efficiency, economic viability, and environmental factors when integrating PV panels into building façades. The process begins with importing 3D models of buildings from Google Maps into Rhinoceros 3D software. After simplifying the building geometry, a deep learning model is used to identify areas suitable for PV installation, primarily the walls. PV generation and energy demand simulation models are then defined, and an evolutionary multi-objective optimization engine is utilized to determine the best PV system design parameters, including tilt, azimuth, and rotation angles, as well as the vertical and horizontal distances of the panels. This holistic approach allows engineers to thoroughly assess multiple sustainability aspects related to various PV system layouts and make informed decisions based on their preferences.

The framework is applied to two buildings situated in a cold climate on the North Campus of the University of Alberta in Edmonton, Alberta, Canada, serving as case study examples. The results demonstrate that adjusting the priorities of objectives can lead to different optimized solutions, emphasizing the importance of considering various factors when designing PV systems for building façades.
Adaptive Multi-paddock Grazing Increases Organic Carbon in Grassland Soils
Creators: Silva Sobrinho, Laio
Publisher: name: University of Alberta Library
Year: 2023

Grasslands cover 30% of the planet’s terrestrial surface and provide habitat and forage for livestock and wildlife. In addition, grasslands have the potential to mitigate climate change by sequestering substantial amounts of carbon (C) in the soil. However, the ability of grassland soils to sequester C varies greatly depending on the grazing management system adopted. This study examined the difference in soil organic C (SOC) mass between two different grazing systems, including adaptive multi-paddock (AMP) grazing, which involves rotating livestock through many small paddocks based on forage availability and allowing extended rest periods between grazing events, and conventional grazing (i.e., neighboring to AMP, hereafter n-AMP, varying from continuous to slow or fast rotational grazing, representative of the typical variation in grazing practices observed on-farm). I evaluated the effects of diverse grazing practices on SOC in soil depths up to 1 meter, using equivalent soil mass (ESM) to offset differences in soil bulk density among different paddocks, thus ensuring the proper comparison of grazing system effects on SOC mass. Soil samples were collected from 26 ranch pairs, where one ranch practiced AMP while the other n-AMP grazing across the Canadian prairies. In addition to assessing differences in equivalent SOC mass between grazing systems at the treatment level (AMP vs. n-AMP), I used an information theoretic model selection approach to assess the influence of nuanced grazing management practices, including stocking rate, animal stock density, and rest intervals, on SOC. My results show AMP grazed grasslands with higher stocking rates and extended rest periods sequestered significantly more SOC in the 10-30 cm ESM soil layer than n-AMP grazed grasslands. Conversely, n-AMP can sequester more SOC than AMP grazing at stocking rates lower than 3.5 AUM ha-1. These results highlight the importance of using sampling protocols that encompass deeper soil layers to adequately quantify the effect of grazing management on SOC. This study emphasizes the potential for enhancing soil C sequestration in grazed grasslands through the use of rotational grazing systems at adequate stocking rates.
Plant Metabolomics and Terpenoid Profiling by GC×GC-TOFMS: Strategies on Sample Analysis and Data Handling for Large or Multi-Year Studies
Creators: Dias, Ryan
Publisher: name: University of Alberta Library
Year: 2023

Since the days of Hippocrates, it has been generally accepted that the human body and the bodies of all living things emit different odors when sick or stressed. Rather than sniffing patients’ urine, modern researchers apply the metabolomics approach to measure metabolite levels and infer biological changes. Metabolomics is the newest of the “omics” fields, preceded by genomics, proteomics and transcriptomics, respectively. In general, metabolomics refers to the study of all—or as close as possible—metabolites contained in a biological sample that may impart information about the health or condition of the subject. The problem for these studies becomes discovering the compounds that signal a biological change in an overwhelming background of irrelevant compounds.

Another consideration must be made for the sample preparation—the choice of analytical instrumentation should be fit-for-purpose. In an ideal world, the analytical platform for a metabolomics study would be able to analyze a wide array of chemical compounds across a large range of physiological concentrations. Though the “holy grail” of metabolomics has not been described or developed yet, comprehensive two-dimensional gas chromatography (GC×GC) is an attractive platform to obtain the volatile metabolome of almost any sample type. GC×GC has started receiving recognition for its applicability to metabolomics, but the greatest challenge still is handling the large datasets produced by the technique.

Work presented herein is devoted to handling large GC×GC datasets obtained from a variety of plant metabolomics studies. Throughout this body of work, specific attention is paid to the terpenoids detected in each study: this class of compounds continually proves itself useful in plant analyses. This thesis discusses the whole workflow, from sample preservation to analytical instrumentation to data analysis, and makes recommendations at each step of the analytical process. GC×GC lends itself to be a powerful tool for volatile metabolomics studies, and is best suited for some of the discovery studies described in the coming chapters. The hope is that the suggestions made in this thesis inform future plant metabolomics studies on the best practices for biomarker discovery by GC×GC and “big data”-handling strategies.
Microwave Heating Of Non-Aqueous Oil Sands Extraction Gangue: Study Of Optimal Cyclohexane-Water Mass Ratio And Solvent Recovery Rate
Creators: Dos Santos De Araujo, Filipe
Publisher: name: University of Alberta Library
Year: 2023

Non-aqueous bitumen extraction processes (NAE) of mined oil sands ore have been investigated to circumvent the environmental and operating limitations of the current hot water-based technology.

However, one primary challenge of NAE is a solvent recovery that meets environmental and economic constraints. Microwave heating (MWH) has been identified as a possible solution due to its selective and rapid heating nature. Nonetheless, this technology is still in the early stages of development, requiring a better understanding of concentrations of solvent and fines that are industrially relevant. Therefore, this work quantifies the solvent removal (cyclohexane) from NAE reconstituted gangue using MWH across different concentrations of cyclohexane, fines particles, and water (MWH absorber). Based on the previous literature, two main mechanisms are suggested for the solvent removal from NAE reconstituted gangue. The main mechanism is attributed to the selective heating of water that efficiently transfers energy to the cyclohexane which vaporizes. Additionally, cyclohexane is removed by steam stripping due to the water vapor generated in the MHW process.

In addition, findings demonstrate that a minimum mass ratio of water/cyclohexane of 1/2 is enough to reduce cyclohexane concentration to undetectable levels (150 ppm) after 780 seconds, in agreement with the previous literature. Therefore, a water/cyclohexane mass ratio of 1/2 was employed to investigate the removal rate of cyclohexane for samples with fine concentrations of 10 and 20 wt% as well as cyclohexane concentrations of 6 and 12 wt%. The experimental data reveal an excellent agreement with a simple Lewis exponential drying model. Moreover, regardless of the initial cyclohexane concentration, a higher fine content results in a shorter vaporization time and a faster solvent removal rate. Fine particles exhibit a specific surface area significantly higher than coarse solids. Therefore, this behavior is attributed to an improvement in heat transfer efficiency promoted by an increased contact area between the heating agent or microwave absorber (water) and the sample. Such results demonstrate an improvement compared to conventional heating which is approximately  3 times slower for low-grade ore (higher fines content). The initial cyclohexane concentration, however, did not substantially affect the removal rate at the same fine concentrations. Overall, the findings show that MWH can effectively remove cyclohexane from NAE gangue, meeting economic and environmental constraints, laying the foundation for developing a greener NAE technology, and supporting the efforts of the oil sands industry to achieve net zero emissions.

The Nexus of Public Perceptions of Contemporary Energy Technologies in the Face of Climate Change
Creators: Mohammed, Abdul-Hamid
Publisher: name: University of Alberta Library
Year: 2023

The pressure to achieve net-zero CO2 objectives has heightened the need to evaluate energy technologies in Canada, where the oil and gas industry remains essential to the economy. Carbon capture and storage (CCS) is a component of Canada’s net-zero CO2 strategies and can absorb up to 90% of the CO2 emissions from major point emitters. However, public perception and support for CCS remain controversial. Hydraulic fracturing (HF), on the other hand, is a non-conventional method of extracting oil and natural gas, with growing public concern about its impact on environmental quality and human health. This study investigated the reasons for the heterogeneity in acceptance and support for CCS and HF in Canada. Random effects and latent class models were applied to vignette experimental data to investigate the public's perceptions of CCS as a climate mitigation technology and HF, respectively. Our findings indicate that cross-border import of CO2 for storage has a strong effect on the acceptance of CCS plant scenarios. Consultation, compensation, proximity, knowledge, risks, and trust are key drivers of CCS acceptance. Public perceptions of HF have also varied. Economic benefits to the community, citizen consultation on HF, proximity, and the likelihood and severity of HF-induced seismicity had the largest effects on individuals’ support (ratings) for the proposed HF projects. Supporters of HF tend to be men living in rural areas who have a high level of education and knowledge about the energy sector, whereas HF protesters tend to be college-educated women who are worried about the negative effects of HF. The ratings of HF scenarios by clean energy supporters tend to hinge on proximity, community consultation, and HF-induced seismicity risks. The study concluded that communication efforts to improve public understanding and acceptance of CCS should focus on demystifying the risks of CCS instead of its technicalities and climate mitigation capacity. In addition, prioritising local firms and services in contracts and providing compensation directly to affected individuals can lead to greater public support for HF projects.

description: Unusually high bending flexibility has been recently reported for DNA on short length scales. We use atomic force microscopy (AFM) in solution to obtain a direct estimate of DNA bending statistics for scales down to one helical turn. It appears that DNA behaves as a Gaussian chain and is well described by the worm-like chain model at length scales beyond 3 helical turns (10.5nm). Below this threshold, the AFM data exhibit growing noise because of experimental limitations. This noise may hide small deviations from the Gaussian behavior, but they can hardly be significant.

description: Analysis of the transit timing variations (TTVs) of candidate pairs near mean-motion resonances (MMRs) is an effective method to confirm planets. Hitherto, 68 planets in 34 multi-planet systems have been confirmed via TTVs. We analyze the TTVs of all candidates from the most recent Kepler data with a time span as long as about 1350 days (Q0-Q15). The anti-correlations of TTV signals and the mass upper limits of candidate pairs in the same system are calculated, using an improved method suitable for long-period TTVs. If the false alarm probability (FAP) of a candidate pair is less than 10^{-3} and the mass upper limit for each candidate is less than 13 M_J, we confirm them as planets in the same system. Finally, 8 planets in 4 multi-planet systems are confirmed via analysis of their TTVs. All of the 4 planet pairs are near first-order MMRs, including KOI-2672 near 2:1 MMR, KOI-1236, KOI-1563 and KOI-2038 near 3:2 MMR. Four planets have relatively long orbital periods (> 35 day). KOI-2672.01 has a period of 88.51658 days and a fit mass of 17 M_\oplus. It is the longest-period planet confirmed, to date, near first-order MMR via TTVs.

description: We propose a new model for the hemispherical power asymmetry of the CMB based on modulated reheating. Non-Gaussianity from modulated reheating can be small enough to satisfy the bound from Planck if the dominant modulation of the inflaton decay rate is linear in the modulating field $σ$. $σ$ must then acquire a spatially-modulated power spectrum with a red scale-dependence. This can be achieved if the primordial perturbation of $σ$ is generated via tachyonic growth of a complex scalar field. Modulated reheating due to $σ$ then produces a spatially modulated and scale-dependent sub-dominant contribution to the adiabatic density perturbation. We show that it is possible to account for the observed asymmetry while remaining consistent with bounds from quasar number counts, non-Gaussianity and the CMB temperature quadupole. The model predicts that the adiabatic perturbation spectral index and its running will be modified by the modulated reheating component.

To accurately reflect the impact of pelvic organ prolapse (POP) from the patient's perspective, PROMs must have strong measurement properties such as validity, reliability, and responsiveness. The aim was to conduct a systematic review of studies reporting on the measurement properties of PROMs used in both surgical and conservative management settings for evaluating POP.

Methods: Medline, EMBASE, CINAHL, Scopus, and Cochrane databases were searched from inception to May 2022 for studies that evaluated female adults with a diagnosis of or seeking treatment for POP. Studies were eligible if they involved 1) at least one group of female adults diagnosed with or presenting with symptoms of POP; 2) a self-reported outcome measure (PROMs, questionnaires) to evaluate POP-related domains; and 3) at least one measurement property including PROM development, content validity, internal consistency, reliability, measurement error, concurrent validity, discriminative validity, and/or responsiveness. Methodological quality was assessed using the COSMIN risk of bias (ROB) checklist, and measurement quality was determined using the COSMIN criteria for good measurement properties.

Results: 2,495 abstracts were screened, and 68 full-text articles were reviewed, from which 12 studies met the selection criteria and were included in this review. The most frequently evaluated measurement properties were internal consistency (6 PROMs, five studies) and responsiveness (11 PROMs, ten studies). Most PROMs received a sufficient rating for the measurement quality of responsiveness in a surgical setting. Only five studies evaluated PROM responsiveness in the conservative management setting, and while most showed sufficient evidence of responsiveness, due to a small number of studies and small sample sizes, confidence in the reported quality of this measurement property is low for conservative settings.

Conclusion: This original work identified a gap in evidence regarding the measurement qualities of identified PROMs used in the POP population. Few PROMs have empirical evidence supporting their content validity and responsiveness for evaluating the effectiveness of conservative interventions. Further research is needed to assess the full spectrum of measurement properties identified by COSMIN when considering existing PROMs used for those with POP.

description: Stimulated by the proton radius conundrum, measurements of the Lamb shift in various light muonic atoms are planned at PSI. The aim is to extract the rms charge radius with high precision, limited by the uncertainty in the nuclear polarization corrections. We present an ab-initio calculation of the nuclear polarization for mu-4He+ leading to an energy correction in the 2S-2P transitions of $δ_{pol}=-2.47$ meV $\pm$ 6%. We use two different state-of-the-art nuclear Hamiltonians and utilize the Lorentz integral transform with hyperspherical harmonics expansion as few-body methods. We take into account the leading multipole contributions, plus Coulomb, relativistic and finite-nucleon-size corrections. Our main source of uncertainty is the nuclear Hamiltonian, which currently limits the attainable accuracy. Our predictions considerably reduce the uncertainty with respect to previous estimates and should timely serve the mu-4He+ experiment planned for 2013.

description: A prominent formulation of the uncertainty principle identifies the fundamental quantum feature that no particle may be prepared with certain outcomes for both position and momentum measurements. Often the statistical uncertainties are thereby measured in terms of entropies providing a clear operational interpretation in information theory and cryptography. Recently, entropic uncertainty relations have been used to show that the uncertainty can be reduced in the presence of entanglement and to prove security of quantum cryptographic tasks. However, much of this recent progress has been focused on observables with only a finite number of outcomes not including Heisenberg's original setting of position and momentum observables. Here we show entropic uncertainty relations for general observables with discrete but infinite or continuous spectrum that take into account the power of an entangled observer. As an illustration, we evaluate the uncertainty relations for position and momentum measurements, which is operationally significant in that it implies security of a quantum key distribution scheme based on homodyne detection of squeezed Gaussian states.
