description: A patient with glioblastoma mutliforme underwent serial computerized analysis of tumor-associated vasculature defined from magnetic resonance angiographic (MRA) scans obtained over almost a four year period. The clinical course included tumor resection with subsequent radiation therapy, a long symptom-free interval, emergence of a new malignant focus, resection of that focus, a stroke, and treatment with chemotherapy and anti-angiogenic therapy. Image analysis methods included segmentation of vessels from each MRA and statistical comparison of vessel morphology over 4 regions of interest (the initial tumor site, the second tumor site, a distant control region, and the entire brain) to the same 4 regions of interest in 50 healthy volunteers (26 females and 24 males; mean age 39 years). Results suggested that following completion of focal radiation therapy (RT) vessel shape abnormalities, if elevated at the time of RT completion, may progressively normalize for months in focal regions, that progressively severe vessel shape abnormalities can precede the emergence of a gadolinium enhancing lesion by months, that lesion resection can produce a dramatic but highly transient drop in abnormal vessel tortuosity both focally and globally, and that treatment with anti-angiogenic agents does not necessarily normalize vessel shape. Quantitative measurements of vessel morphology as defined from MRA may provide useful insights into tumor development and response to therapy.

description: We investigate the fluctuation dynamics of a probe around a deterministic motion induced by interactions with driven particles. The latter constitute the nonequilibrium medium in which the probe is immersed and is modelled as overdamped Langevin particle dynamics driven by nonconservative forces. The expansion that yields the friction and noise expressions for the reduced probe dynamics is based on linear response around a time dependent nonequilibrium condition of the medium. The result contains an extension of the second fluctuation dissipation relation between friction and noise for probe motion in a nonequilibrium fluid
A framework for offsite construction manufacturing process improvement through digitalization and automated real-time data collection
Creators: Barkokebas, Beda
Publisher: name: University of Alberta Library
Year: 2022

This thesis proposes methods to apply real-time data to improve manufacturing operations in offsite construction using a combination of tools such as simulation, machine learning, and exploratory data analysis. These methods are applied to increase flexibility in operations and digitalize the design, planning, and manufacturing phases in offsite construction. Through empirical implementations, the proposed methods provide applications of digitalization to improve offsite construction manufacturing operations by integrating existing information systems while combining and applying design-related and real-time data gathered from shop floors. The proposed framework includes implementation of digitalization strategies in the design, bidding, and procurement phases of offsite construction. The proposed framework also integrates building information modelling with lean-based metrics based on real-time data gathered using radio-frequency identifier sensors logistically installed on a shop floor The proposed method addresses improvement measures using a combination of expert’s knowledge and statistical analysis, thus reducing the impact of personal opinions with respect to proposed changes to the shop floor in favor of empirical analysis supported by actual production data. A simulation-based analysis is also introduced to address the impact of the proposed framework in terms of increasing labour flexibility and reducing the average cycle time of projects in offsite construction. The key contribution of this research is the development of a framework and methods to improve manufacturing operations in offsite construction by leveraging digitalization and real-time data.

description: Diffusion tensor imaging (DTI) provides a unique source of information about the underlying tissue structure of brain white matter in vivo including both the geometry of major fiber bundles as well as quantitative information about tissue properties represented by derived tensor measures. This paper presents a method for statistical comparison of fiber bundle diffusion properties between populations of diffusion tensor images. Unbiased diffeomorphic atlas building is used to compute a normalized coordinate system for populations of diffusion images. The diffeomorphic transformations between each subject and the atlas provide spatial normalization for the comparison of tract statistics. Diffusion properties, such as fractional anisotropy (FA) and tensor norm, along fiber tracts are modeled as multivariate functions of arc length. Hypothesis testing is performed non-parametrically using permutation testing based on the Hotelling T2 statistic. The linear discriminant embedded in the T2 metric provides an intuitive, localized interpretation of detected differences. The proposed methodology was tested on two clinical studies of neurodevelopment. In a study of one and two year old subjects, a significant increase in FA and a correlated decrease in Frobenius norm was found in several tracts. Significant differences in neonates were found in the splenium tract between controls and subjects with isolated mild ventriculomegaly (MVM) demonstrating the potential of this method for clinical studies.

description: We describe a new method to automatically discriminate between patients with Alzheimer's disease (AD) or mild cognitive impairment (MCI) and elderly controls, based on multidimensional classification of hippocampal shape features. This approach uses spherical harmonics (SPHARM) coefficients to model the shape of the hippocampi, which are segmented from magnetic resonance images (MRI) using a fully automatic method that we previously developed. SPHARM coefficients are used as features in a classification procedure based on support vector machines (SVM). The most relevant features for classification are selected using a bagging strategy. We evaluate the accuracy of our method in a group of 23 patients with AD (10 males, 13 females, age±standard-deviation (SD)=73±6 years, mini-mental score (MMS)=24.4±2.8), 23 patients with amnestic MCI (10 males, 13 females, age±SD=74±8 years, MMS=27.3±1.4) and 25 elderly healthy controls (13 males,12 females, age±SD=64±8 years), using leave-one-out cross-validation. For AD vs controls, we obtain a correct classification rate of 94%, a sensitivity of 96%, and a specificity of 92%. For MCI vs controls, we obtain a classification rate of 83%, a sensitivity of 83%, and a specificity of 84%. This accuracy is superior to that of hippocampal volumetry and is comparable to recently published SVM-based whole-brain classification methods, which relied on a different strategy. This new method may become a useful tool to assist in the diagnosis of Alzheimer's disease.
Near-tubular fiber bundle segmentation for diffusion weighted imaging: Segmentation through frame reorientation

description: This paper proposes a methodology to segment near-tubular fiber bundles from diffusion weighted magnetic resonance images (DW-MRI). Segmentation is simplified by locally reorienting diffusion information based on large-scale fiber bundle geometry. Segmentation is achieved through simple global statistical modeling of diffusion orientation. Utilizing a modification of a recent segmentation approach by Bresson et al. allows for a convex optimization formulation of the segmentation problem, combining orientation statistics and spatial regularization. The approach compares favorably with segmentation by full-brain streamline tractography.

description: The crystal structure and chemical bonding of magnetron-sputtering deposited nickel carbide Ni$_{1-x}$C$_{x}$ (0.05$\leq$x$\leq$0.62) thin films have been investigated by high-resolution X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, and soft X-ray absorption spectroscopy. By using X-ray as well as electron diffraction, we found carbon-containing hcp-Ni (hcp-NiC$_{y}$ phase), instead of the expected rhombohedral-Ni$_{3}$C. At low carbon content (4.9 at\%) the thin film consists of hcp-NiC$_{y}$ nanocrystallites mixed with a smaller amount of fcc-NiC$_{x}$. The average grain size is about 10-20 nm. With the increase of carbon content to 16.3 at\%, the film contains single-phase hcp-NiC$_{y}$ nanocrystallites with expanded lattice parameters. With further increase of carbon content to 38 at\%, and 62 at\%, the films transform to X-ray amorphous materials with hcp-NiC$_{y}$ and fcc-NiC$_{x }$ nanodomain structures in an amorphous carbon-rich matrix. Raman spectra of carbon indicate dominant $sp^{2}$ hybridization, consistent with photoelectron spectra that show a decreasing amount of C-Ni phase with increasing carbon content. The Ni $3d$ - C $2p$ hybridization in the hexagonal structure gives rise to the salient double-peak structure in Ni $2p$ soft X-ray absorption spectra at 16.3 at\% that changes with carbon content. We also show that the resistivity is not only governed by the amount of carbon, but increases by more than a factor of two when the samples transform from crystalline to amorphous.

description: MR diffusion tensor imaging (DTI) can measure and visualize organization of white matter fibre tracts in vivo. DTI is a relatively new imaging technique, and new tools developed for quantifying fibre tracts require evaluation. The purpose of this study was to compare the reliability of a novel clustering approach with a multiple region of interest (MROI) approach in both healthy and disease (schizophrenia) populations. DTI images were acquired in 20 participants (n=10 patients with schizophrenia: 56 ± 15 years; n=10 controls: 51 ± 20 years) (1.5 Tesla GE system) with diffusion gradients applied in 23 non-collinear directions, repeated three times. Whole brain seeding and creation of fibre tracts were then performed. Interrater reliability of the clustering approach, and the MROI approach, were each evaluated and the methods compared. There was high spatial (voxel-based) agreement within and between the clustering and MROI methods. Fractional anisotropy, trace, and radial and axial diffusivity values showed high intraclass correlation (p<0.001 for all tracts) for each approach. Differences in scalar indices of diffusion between the clustering and MROI approach were minimal. The excellent interrater reliability of the clustering method and high agreement with the MROI method, quantitatively and spatially, indicates that the clustering method can be used with confidence. The clustering method avoids biases of ROI drawing and placement, and, not limited by a priori predictions, may be a more robust and efficient way to identify and measure white matter tracts of interest.

description: Randolph Air Force Base (AFB) is one of the most significant military installations in America. Constructed during the early 1930s, the base was the center for the Army Air Corps' pilot and pilot instructor training program. As the primary center for pilot training, it was an integral part of the nation’s air defense system before and during World War II. The base continues to serve as the only Pilot-Instructor Training Wing in the United States Air Force. This study provides an historical overview of the development of the base and documents all remaining pre-1950 buildings, structures, and sites. A total of 382 properties meet the criteria of the survey and were inventoried in accordance with standards set forth by the Texas Historical Commission, which serves as the State Historic Preservation Office [SHPO]. The Consultant on this project designed inventory forms expressly suited to the Randolph AFB survey. These 382 forms, along with photographic and mapping documentation, comprise the survey component of the Randolph study.

description: Within our recently proposed generalized nonlocal optical response (GNOR) model, we revisit the fundamental problem of an optically excited plasmonic dimer. The dimer consists of two identical cylinders separated by a nanometre-sized gap. We consider the transition from separated dimers via touching dimers to finally overlapping dimers. In particular, we focus on the touching case, showing a fundamental limit on the hybridization of the bonding plasmon modes due to nonlocality. Using transformation optics we determine a simple analytical equation for the resonance energies of the bonding plasmon modes of the touching dimer.

description: A brain image registration algorithm, referred to as RABBIT, is proposed to achieve fast and accurate image registration with the help of an intermediate template generated by a statistical deformation model. The statistical deformation model is built by principal component analysis (PCA) on a set of training samples of brain deformation fields that warp a selected template image to the individual brain samples. The statistical deformation model is capable of characterizing individual brain deformations by a small number of parameters, which is used to rapidly estimate the brain deformation between the template and a new individual brain image. The estimated deformation is then used to warp the template, thus generating an intermediate template close to the individual brain image. Finally, the shape difference between the intermediate template and the individual brain is estimated by an image registration algorithm, e.g., HAMMER. The overall registration between the template and the individual brain image can be achieved by directly combining the deformation fields that warp the template to the intermediate template, and the intermediate template to the individual brain image. The algorithm has been validated for spatial normalization of both simulated and real magnetic resonance imaging (MRI) brain images. Compared with HAMMER, the experimental results demonstrate that the proposed algorithm can achieve over five times speedup, with similar registration accuracy and statistical power in detecting brain atrophy.

Multiscale Investigation of the Earth's Internal Structure and Processes Using Seismic Arrays
Creators: Wang, Jingchuan
Publisher: name: University of Alberta Library
Year: 2022

The fast expansion of seismic arrays has improved our ability to understand the Earth's internal structure and dynamics at various spatial scales. This thesis applies both conventional and novel approaches to dense array recordings to address major questions in (1) earthquake location and source mechanisms, (2) upper-crustal seismic structure, (3) subduction zone dynamics, and (4) variations in the elastic properties of upper mantle transition zone discontinuities.

We present the first example of a quick-response nodal experiment in western Canada to investigate the spatiotemporal characteristics of a hydraulic fracturing-induced earthquake swarm in central Alberta at a local scale. A high-precision earthquake catalog is constructed using a machine-learning phase picker and a sequential earthquake association and location method. The outcomes capture the geometry of the reactivated faults and highlight the significance of trailing seismicity in hazard assessment. In Chapter 3, a regional background survey of southwestern Canada based on ambient noise tomography reveals lateral variations in both velocity and anisotropy with spatial affinities to major geological domains. We observe strong radial anisotropy in the southern Canadian Cordillera due to crustal extension similar to that observed in the western United States, while the anisotropic anomaly in the Cordilleran foreland may have resulted from horizontal compression during the plate convergence at the western margin of the North American craton. In the third component of the thesis, a self-consistent model of subduction dynamics at transition zone depths beneath South America is presented, through a combined analysis of travel times and amplitudes of underside shear wave reflections. Our updated topography model of transition zone discontinuities suggests contrasting styles of slab-transition zone interaction. A joint analysis of seismic data and mineral physics modeling provides observational evidence for thermochemical anomalies within the mantle. Finally, we expand the underside reflection data set for global coverage, and a novel amplitude-versus-offset inversion is applied to map lateral variations in density jump across the 660-km discontinuity. Major subduction zones are generally featured by low density jumps; this implies a compositional difference with excess basalt relative to the global average.

description: Cognitive radio has been widely considered as one of the prominent solutions to tackle the spectrum scarcity. While the majority of existing research has focused on single-band cognitive radio, multiband cognitive radio represents great promises towards implementing efficient cognitive networks compared to single-based networks. Multiband cognitive radio networks (MB-CRNs) are expected to significantly enhance the network's throughput and provide better channel maintenance by reducing handoff frequency. Nevertheless, the wideband front-end and the multiband spectrum access impose a number of challenges yet to overcome. This paper provides an in-depth analysis on the recent advancements in multiband spectrum sensing techniques, their limitations, and possible future directions to improve them. We study cooperative communications for MB-CRNs to tackle a fundamental limit on diversity and sampling. We also investigate several limits and tradeoffs of various design parameters for MB-CRNs. In addition, we explore the key MB-CRNs performance metrics that differ from the conventional metrics used for single-band based networks.

description: We present the results of the investigation of the nova V1674 Her (2021), recognised as the swiftest classical nova, with $t_2 \sim 0.90$ days. The distance to the nova is estimated to be 4.97 kpc. The mass and radius of the WD are calculated to be $\sim~1.36~M_\odot$ and $\sim 0.15~R_\oplus$, respectively. Over the course of one month following the outburst, V1674 Her traversed distinct phases -- pre-maxima, early decline, nebular, and coronal -- displaying a remarkably swift transformation. The nebular lines emerged on day 10.00, making it the classical nova with the earliest observed commencement to date. We modelled the observed optical spectrum using the photoionization code \textsc{cloudy}. From the best-fitting model we deduced different physical and chemical parameters associated withe the system. The temperature and luminosity of the central ionizing sources are found in the range of $1.99 - 2.34~\times 10^5$ K and $1.26 - 3.16~ \times 10^{38}$ \ergs, respectively. Elements such as He, O, N, and Ne are found to be overabundant compared to solar abundance in both the nebular and coronal phases. According to the model, Fe II abundance diminishes while Ne abundance increases, potentially elucidating the rare hybrid transition between Fe and He/N nova classes. The ejected mass across all epochs spanned from $3.42 - 7.04~ \times 10^{-5}~M_\odot$. Morpho-kinematic modelling utilising \textsc{shape} revealed that the nova V1674 Her possesses a bipolar structure with an equatorial ring at the centre and an inclination angle of i = 67$\pm$ 1.5$^{\circ}$.

description: We propose a novel diffusion tensor imaging (DTI) registration algorithm, called Tensor Image Morphing for Elastic Registration (TIMER), which leverages the hierarchical guidance of regional distributions and local boundaries, both extracted directly from the tensors. Currently available DTI registration methods generally extract tensor scalar features from each tensor to construct scalar maps. Subsequently, regional integration and other operations such as edge detection are performed to extract more features to guide the registration. However, there are two major limitations with these approaches. First, the computed regional features might not reflect the actual regional tensor distributions. Second, by the same token, gradient maps calculated from the tensor-derived scalar feature maps might not represent the actual tissue tensor boundaries. To overcome these limitations, we propose a new approach which extracts regional and edge information directly from a tensor neighborhood. Regional tensor distribution information, such as mean and variance, is computed in a multiscale fashion directly from the tensors by taking into account the voxel neighborhood of different sizes, and hence capturing tensor information at different scales, which in turn can be employed to hierarchically guide the registration. Such multiscale scheme can help alleviate the problem of local minimum and is also more robust to noise since one can better determine the statistical properties of each voxel by taking into account the properties of its surrounding. Also incorporated in our method is edge information extracted directly from the tensors, which is crucial to facilitate registration of tissue boundaries. Experiments involving real subjects, simulated subjects, fiber tracking, and atrophy detection indicate that TIMER performs better than the other methods in comparison (Yang et al., 2008a; Zhang et al., 2006).

description: To achieve more accurate and consistent registration in an image population, a novel hierarchical groupwise registration framework, called Atlas Building by Self-Organized Registration and Bundling (ABSORB), is proposed in this paper. In this new framework, the global structure, i.e., the relative distribution of subject images is always preserved during the registration process by constraining each subject image to deform only locally with respect to its neighbors within the learned image manifold. To achieve this goal, two novel strategies, i.e., the self-organized registration by warping one image towards a set of its eligible neighbors and image bundling to cluster similar images, are specially proposed. By using these two strategies, this new framework can perform groupwise registration in a hierarchical way. Specifically, in the high level, it will perform on a much smaller dataset formed by the representative subject images of all subgroups that are generated in the previous levels of registration. Compared to the other groupwise registration methods, our proposed framework has several advantages: 1) It explores the local data distribution and uses the obtained distribution information to guide the registration; 2) The possible registration error can be greatly reduced by requiring each individual subject to move only towards its nearby subjects with similar structures; 3) It can produce a smoother registration path, in general, from each subject image to the final built atlas than other groupwise registration methods. Experimental results on both synthetic and real datasets show that the proposed framework can achieve substantial improvements, compared to the other two widely used groupwise registration methods, in terms of both registration accuracy and robustness.
Diamino Diacid Macrocyclization of Apelin and Neopetrosiamide
Creators: Pascoe, Cameron
Publisher: name: University of Alberta Library
Year: 2022

Peptides can elicit a whole host of beneficial physiological effects. The market for peptide-based therapeutics is rapidly expanding due to their extreme specificity and low toxicity. Conversely, they often possess poor bioavailability, stability, pharmacokinetics and cell permeability, limiting their therapeutic potential. Macrocyclization of peptides has been used to increased peptide stability and cell permeability. Described herein is the expansion of chemistry to increase the accessibility of orthogonally protected diamino diacids and the efforts towards their incorporation to create carbon-based macrocycles of two biologically active peptides. An investigation into their activity through the use of biological assays is also presented.

Chapter 2 discusses efforts toward the synthesis of differentially protected diamino diacids. These molecules can be used to efficiently incorporate macrocycles into peptides and mimic natural linkages that are susceptible to degradation and strengthen them. The attempted use of a solid support to assist the synthesis of diaminosuberic acid analogues is described along with the use of a 1,2-benzenedimethanol scaffold to expand the orthogonally protected diamino diacids available using this methodology from one to four. Each of the synthesized diamino diacids analogues produced is immediately SPPS amenable.

Chapter 3 discusses the synthesis of methylene analogues of neopetrosiamide as potential antimetastatic agents. Neopetrosiamide is a 28-residue peptide isolated from a marine sponge that contains three disulfide bonds. It has been shown to inhibit mammalian tumour invasion in vitro but requires precise connectivity of the disulfide bonds for activity. Single disulfide bond replacement by methylene bridges through pre-stapling of the peptide using orthogonally protected diaminosuberic acid results in three new active analogues comparable in activity to the native peptide and enhances correct folding of the remaining disulfide bonds. Formation of the remaining disulfide bonds is simplified to a single step, followed by HPLC purification.

Chapter 4 discusses the synthesis of apelin analogues. Apelin is a peptide that evokes significant cardio-protective effects such as increased myocardial contractility, increased heart rate and blood pressure lowering. However, apelin’s therapeutic use is drastically hindered due to rapid degradation in plasma due to multiple degradation sites. Attempts for more stable analogues by isostere substitution of the KLKB1 degradation sites resulted in stable analogues able to evoke a biological response, however, at concentrations too high to be effective. Additional analogues incorporating macrocycles of the C-terminus with orthogonally protected diamino diacids to increase plasma stability and cell permeability were synthesized but proved to be inactive.

Women's Experiences of Self-Compassion in Coping with Sexual Problems Following a Sexual Assault
Creators: Campbell, Debra J
Publisher: name: University of Alberta Library
Year: 2022

The majority of sexual assault incidents in Canada are committed against women and girls. Among the many injurious sequelae survivors can experience post-sexual assault are sexual problems. Sexual concerns related to desire, arousal, pain, orgasm and/or sexual well-being can last for years after the assault. Given the strong association between sexual well-being and both mental and physical health, it is crucial to understand how women effectively cope with sexual concerns stemming from sexual assault. Although self-compassion has been studied as a positive way of coping with other forms of trauma, no study to date has examined self-compassion’s role in addressing the needs of female sexual assault survivors, specific to sexual issues. Thus, this study explored women’s experiences of self-compassion in coping with sexual problems following a sexual assault. Interpretative phenomenological analysis (IPA) was used to explore in detail how female survivors made sense of their world and the meanings these experiences held for them. Data were collected from 10 women across Canada in the form of semi-structured interviews held either in person or over the phone. Data analysis revealed eight themes: (a) honouring time, (b) quieting the inner critic, (c) connecting with social supports, (d) countering societal messages, (e) asserting personal boundaries and taking control, (f) engaging in regular self-care, (g) rebuilding a relationship with one’s body, and (h) persevering through emotional challenges. Clinical implications, limitations, and direction for future research are also discussed.

description: The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory has been in operation since 2000. Over the past decade, the luminosity in the polarized proton (p-p) operations has increased by more than one order of magnitude. The maximum total beam-beam tune shift with two collisions has reached 0.018. The beam-beam interaction leads to large tune spread, emittance growth, and short beam and luminosity lifetimes. In this article, we review the beam-beam observations during the previous RHIC p-p runs. The mechanism for particle loss is presented. The intra-beam scattering (IBS) contributions to emittance and bunch length growths are calculated and compared with the measurements. Finally, we will discuss current limits in the RHIC p-p operations and their solutions.

description: We put forward an operational degree of polarization that can be extended in a natural way to fields whose wave fronts are not necessarily planar. This measure appears as a distance from a state to the set of all its polarization-transformed counterparts. By using the Hilbert-Schmidt metric, the resulting degree is a sum of two terms: one is the purity of the state and the other can be interpreted as a classical distinguishability, which can be experimentally determined in an interferometric setup. For transverse fields, this reduces to the standard approach, whereas it allows one to get a straight expression for nonparaxial fields.
