Development of Multi-Functional Add-On Hybrid Armor Models and Designs used for Vehicle Protection
Creators: Pisavadia, Harshil H
Publisher: name: University of Alberta Library
Year: 2022

In the first part of this thesis, a validated polyurethane adhesive model is implemented into a system-scale ceramic/armor model for ballistic impact simulations. Here, the trilinear cohesive zone (TCZM) technique is used to simulate the dynamic failure of SikaForceTM6 7752-L60 polyurethane adhesive which is used to bond the alumina ceramic layer to the aluminum metal backing in add-on armor vehicle systems. The effect of adhesive thicknesses, manufacturing defects, and strain rates on the armor performance are explored. Armor performance was found to decrease with increasing adhesive thicknesses and defects (trapped air bubbles). Including strain rate terms in the material model increased the overall damage area of the adhesive, thus predicting a decrease in multi-hit capabilities. Overall, novel insights are provided for modelling adhesives using the TCZM technique in ceramic/metal armor systems.In the second part of this thesis, optical models are developed for micro- and macro-scale polyethylene-based metamaterials for thermal signature management applications. Specifically, micro-scale post and macro-scale lenticular lens designs (singleand sandwiched configurations) are explored for achieving thermal radiation control. The micro-scale post design was found to be highly emissive-tuneable through varying post configurations (e.g., post width, height, and spacings). Actively actuating the post configuration through strain modulation allowed to redshift the emissivity. The macro-scale lenticular lens configurations exhibited emissive stability for a range of configurations (e.g., lens radii, height, and strain modulation). In summary, the proposed polyethylene-based metamaterial models inform manufacturers of military vehicles and other equipment on designs for thermal signature management solutions.

description: Human apolipoprotein E (apoE) exists in three isoforms: apoE2, apoE3 and apoE4. APOE ε4 (E4) is a major genetic risk factor for cardiovascular disease (CVD) and Alzheimer's disease (AD). ApoE mediates cholesterol metabolism by binding various receptors. The low-density lipoprotein receptor (LDLR) has a high affinity for apoE, and is the only member of its receptor family to demonstrate an apoE isoform specific binding affinity (E4>E3>>E2). Evidence suggests that a functional interaction between apoE and LDLR influences the risk of CVD and AD. We hypothesize that the differential cognitive effects of the apoE isoforms are a direct result of their varying interactions with LDLR. To test this hypothesis, we have employed transgenic mice that express human apoE2, apoE3, or apoE4, and either human LDLR (hLDLR) or no LDLR (LDLR−/−). Our results show that plasma and brain apoE levels, cortical cholesterol, and spatial memory are all regulated by isoform-dependent interactions between apoE and LDLR. Conversely, both anxiety-like behavior and cued associative memory are strongly influenced by APOE genotype, but these processes appear to occur via an LDLR-independent mechanism. Both the lack of LDLR and the interaction between E4 and the LDLR were associated with significant impairments in the retention of long term spatial memory. Finally, levels of hippocampal apoE correlate with long term spatial memory retention in mice with human LDLR. In summary, we demonstrate that the apoE-LDLR interaction affects regional brain apoE levels, brain cholesterol, and cognitive function in an apoE isoform-dependent manner.

description: Icosahedral nanoparticles composed of fivefold twinned tetrahedra have broad applications. The strain relief mechanism and angular deficiency in icosahedral multiply twinned particles are poorly understood in three dimensions. Here, we resolved the three-dimensional atomic structures of Janus icosahedral nanoparticles using atomic resolution electron tomography. A geometrically fivefold face consistently corresponds to a less ordered face like two hemispheres. We quantify rich structural variety of icosahedra including bond orientation order, bond length, strain tensor; and packing efficiency, atom number, solid angle of each tetrahedron. These structural characteristics exhibit two-sided distribution. Edge dislocations near the axial atoms and small disordered domains fill the angular deficiency. Our findings provide new insights how the fivefold symmetry can be compensated and the geometrically-necessary internal strains relived in multiply twinned particles.

description: The present study contributes to an increased understanding of pyro-convection phenomena by using a fire-atmosphere coupled simulation, and investigates in detail the large-scale meteorological conditions affecting Portugal during the occurrence of multiple mega-fires events on 15 October 2017. Two numerical simulations were performed using the MesoNH atmospheric model. The first simulation, was run for a large single domain (300 x 250 grid points) with a 15 km resolution. In the second one, the MesoNH was coupled to a fire propagation model (ForeFire) to study in detail the Quiaios's fire. To optimize both high resolution in the proximity of the fire region and computational efficiency, the simulation is set up using 3 nested domains (300 x 300 grid points) with horizontal resolution of 2000 m, 400 m, and 80 m respectively. The emission into the atmosphere of the heat and the water vapour fluxes caused by the evolving fire is managed by the ForeFire code. The fire spatio-temporal evolution is based on an assigned map, which follows what reported by public authorities. At the large scale, the simulation shows the evolution of the hurricane Ophelia, pointing out the influence of south/southwest winds on the rapid spread of active fires, as well as the subtropical moisture transport toward mainland Portugal in the early evening, when violent pyro-convective activity was observed in Central Portugal. The coupled simulation allowed to reproduce the formation of a PyroCu cloud inside the smoke plume. The convective updraughts caused by the fire led to the vertical transport of water vapour to higher levels and enhanced the development of a high-based cloud over a dry atmospheric layer within the smoke plume.
The Impact of Prenatal Mental Health Disorders on Birth Outcomes before and during the COVID-19 Pandemic in Anhui, China
Creators: Zhao, Tianqi
Publisher: name: University of Alberta Library
Year: 2022

Adverse birth outcomes, including low birth weight, preterm birth, and small for gestational age are associated with increased neonatal morbidity and mortality globally. In China, adverse birth outcomes remain challenging public health problems. Prenatal depression and anxiety have been found to be associated with these adverse birth outcomes. In China, there is increasing literature that reported the importance and severity of prenatal depression and anxiety. The severity of the COVID-19 pandemic is likely to exacerbate mental health problems during the prenatal period and increase the risk of adverse birth outcomes, possibly adding further burden to the current healthcare system in China. The aim of this research is to explore the impacts of prenatal mental health issues on birth outcomes before and during the COVID-19 pandemic in Anhui, China. Insights generated through this work will help fill an existing knowledge gap in China and help stakeholders to gain a better understanding of how the pandemic could have impacted perinatal health.A scoping review methodology was used in Chapter 2 to identify peer-reviewed articles published from late 2019 to the end of July 2021. After removing duplicates, 642 articles were identified, of which two full texts were included for analysis. Both articles highlighted that pregnant women have experienced increasing prenatal mental health issues during the COVID-19 pandemic and, further, increased risk of developing adverse birth outcomes. This scoping review highlighted that there is a lack of research on the impact of prenatal mental health issues on birth outcomes during the pandemic.Study presented in Chapter 3 found that during the pandemic, the prevalence of prenatal depression and anxiety decreased compared to levels before the pandemic. The prevalence of adverse birth outcomes, including low birth weight, preterm birth and small for gestational age also slightly decreased after the pandemic occurred, but the differences were not significant and could be due to other factors, such as sample differences. Interestingly, this study showed that higher PHQ-9 measured depression scores were significantly associated with higher infant birth weights (β=5.51, 95% CI 0.21 to 10.81, p=0.042) and longer gestation age (β=0.02, 95% CI 0.001 to 0.04, p=0.03). Furthermore, EPDS measured prenatal depression and GAD-7 measured anxiety were not significantly associated with birth outcomes. In addition, findings also provided insights into prenatal mental health disorders and adverse birth outcomes by exploring the sociodemographic risk factors for prenatal depression and anxiety, preterm birth, low birth weight and small for gestational age before and during the pandemic in Anhui.

description: WISE J085510.83-071442.5 was recently discovered as the coldest known brown dwarf based on four epochs of images from the Wide-field Infrared Survey Explorer and the Spitzer Space Telescope. We have improved the accuracy of its parallax measurement by obtaining two additional epochs of Spitzer astrometry. We derive a parallactic distance of 2.31+/-0.08 pc, which continues to support its rank as the fourth closest known system to the Sun when compared to WISE J104915.57-531906.1 AB (2.02+/-0.02 pc) and Wolf 359 (2.386+/-0.012 pc). The new constraint on the absolute magnitude at 4.5um indicates an effective temperature of 235-260 K based on four sets of theoretical models. We also show the updated positions of WISE J085510.83-071442.5 in two color-magnitude diagrams. Whereas Faherty and coworkers cited its location in MW2 versus J-W2 as evidence of water clouds, we find that those data can be explained instead by cloudless models that employ non-equilibrium chemistry.

description: Self-testing is a device independent method which can be used to determine the nature of a physical system or device, without knowing any detail of the inner mechanism or the physical dimension of Hilbert space of the system. The only information required are the number of measurements, number of outputs of each measurement and the statistics of each measurement. Earlier works on self testing restricted either to two parties scenario or multipartite graph states. Here, we construct a method to self-test the three-qubit $W$ state, and show how to extend it to other pure three-qubit states. Our bounds are robust against the inevitable experimental errors.

Increased expression of the dopamine transporter leads to loss of dopamine neurons, oxidative stress and l-DOPA reversible motor deficits

description: The dopamine transporter is a key protein responsible for regulating dopamine homeostasis. Its function is to transport dopamine from the extracellular space into the presynaptic neuron. Studies have suggested that accumulation of dopamine in the cytosol can trigger oxidative stress and neurotoxicity. Previously, ectopic expression of the dopamine transporter was shown to cause damage in non-dopaminergic neurons due to their inability to handle cytosolic dopamine. However, it is unknown whether increasing dopamine transporter activity will be detrimental to dopamine neurons that are inherently capable of storing and degrading dopamine. To address this issue, we characterized transgenic mice that over-express the dopamine transporter selectively in dopamine neurons. We report that dopamine transporter over-expressing (DAT-tg) mice display spontaneous loss of midbrain dopamine neurons that is accompanied by increases in oxidative stress markers, 5-S-cysteinyl-dopamine and 5-S-cysteinyl-DOPAC. In addition, metabolite-to-dopamine ratios are increased and VMAT2 protein expression is decreased in the striatum of these animals. Furthermore, DAT-tg mice also show fine motor deficits on challenging beam traversal that are reversed with L-DOPA treatment. Collectively, our findings demonstrate that even in neurons that routinely handle dopamine, increased uptake of this neurotransmitter through the dopamine transporter results in oxidative damage, neuronal loss and LDOPA reversible motor deficits. In addition, DAT over-expressing animals are highly sensitive to MPTP-induced neurotoxicity. The effects of increased dopamine uptake in these transgenic mice could shed light on the unique vulnerability of dopamine neurons in Parkinson’s disease.

description: Autism is characterized by abnormal prefrontal brain activation during cognitive control, a potential biomarker of repetitive behaviors. In this proof-of-principle study, functional magnetic resonance imaging (fMRI) was used to examine brain activity during an oddball task in two high-functioning males with autism before and after 12 weeks of treatment with citalopram, a selective serotonin reuptake inhibitor. One participant showed marked reductions in repetitive behaviors whereas the other showed mild worsening. Brain activation in relevant prefrontal regions increased in only the participant whose repetitive behavior symptoms improved. These findings suggest that fMRI may elucidate potential mechanisms of action of targeted autism interventions.

description: Ethanol causes pathological changes in GABAA receptor trafficking and function. These changes are mediated in part by ethanol activation of protein kinase A (PKA). The current study investigated the expression of the GABAA α1 and α4 subunits and the kinase anchoring protein AKAP150, as well as bicuculline-induced seizure threshold, at baseline and following acute injection of ethanol (3.5 g/kg IP) in a mouse line lacking the regulatory RIIβ subunit of PKA. Whole cerebral cortices were harvested at baseline, 1 h, or 46 h following injection of ethanol or saline and subjected to fractionation and western blot analysis. Knockout (RIIβ−/−) mice had similar baseline levels of PKA RIIα and GABAA α1 and α4 subunits compared to wild type (RIIβ+/+) littermates, but had deficits in AKAP150. GABAA α1 subunit levels were decreased in the P2 fraction of RIIβ−/−, but not RIIβ+/+, mice following 1 h ethanol, an effect that was driven by decreased α1 expression in the synaptic fraction. GABAA α4 subunits in the P2 fraction were not affected by 1 h ethanol; however, synaptic α4 subunit expression was increased in RIIβ+/+, but not RIIβ−/− mice, while extrasynaptic α4 expression was decreased in RIIβ−/−, but not RIIβ+/+ mice. Finally, RIIβ knockout was protective against bicuculline-induced seizure susceptibility. Overall, the results suggest that PKA has differential roles in regulating GABAA receptor subunits. PKA may protect against ethanol-induced deficits in synaptic α1 and extrasynaptic α4 receptors, but may facilitate the increase of synaptic α4 receptors.

description: We introduce a new correlation-based measure of spike timing reliability. Unlike other measures, it does not require the definition of a posteriori “events”. It relies on only one parameter, which relates to the timescale of spike timing precision. We test the measure on surrogate data sets with varying amounts of spike time jitter, and missing or additional spikes, and compare it with a widely used histogram-based measure. The measure is efficient and faithful in characterizing spike timing reliability and produces smaller errors in the reliability estimate than the histogram-based measure based on the same number of trials.

description: The brain produces dynamical rhythms at many frequencies that shift in amplitude and phase. To understand the functional consequences of mixtures of oscillations at the single cell level, we recorded the spike trains from single rat cortical neurons in vitro in response to two mixed sine wave currents. The reliability of spike timing was measured as a function of the relative power, phase and frequencies of the sine wave mixture. Peaks in the reliability were observed at a preferred phase difference, frequency and relative power. These results have a natural interpretation in terms of spike train attractors and bifurcations.

description: Salient object detection has been attracting a lot of interest, and recently various heuristic computational models have been designed. In this paper, we formulate saliency map computation as a regression problem. Our method, which is based on multi-level image segmentation, utilizes the supervised learning approach to map the regional feature vector to a saliency score. Saliency scores across multiple levels are finally fused to produce the saliency map. The contributions lie in two-fold. One is that we propose a discriminate regional feature integration approach for salient object detection. Compared with existing heuristic models, our proposed method is able to automatically integrate high-dimensional regional saliency features and choose discriminative ones. The other is that by investigating standard generic region properties as well as two widely studied concepts for salient object detection, i.e., regional contrast and backgroundness, our approach significantly outperforms state-of-the-art methods on six benchmark datasets. Meanwhile, we demonstrate that our method runs as fast as most existing algorithms.

The impact of rotation and magnetism on the stochastic excitation of acoustic modes

description: Amplitudes of acoustic modes in solar-like stars are intrinsically linked to the properties of turbulent convection in their envelope, which acts as their excitation source. Recent observational works, using results from the Kepler space mission, showed that acoustic modes’ signals are not detected in a large fraction of solar-type stars, where they are nevertheless expected because of their convective envelope. This non-detection is a function of both stellar magnetism and rotation. One hypothesis is that the excitation source term is too low to trigger the oscillations. In addition, observations of solar-type stars show that the amplitudes of these stellar acoustic modes are modulated along their magnetic activity cycles. A key to understanding these observations could be to remember that rotation and magnetic fields strongly influence convection. Their action is most of the time ignored in the models that allow astrophysicists to predict acoustic modes’ amplitudes. To assess the impact of rotation and magnetic field, we extend the state-of-the-art of the formalism describing the stochastic excitation of stellar acoustic modes. We show that the turbulent source terms are modified by the presence of rotation and magnetism. We illustrate how the acoustic waves' amplitudes are modulated, depending on their rotation period and their magnetic activity. This work helps predict their detectability in rotating magnetic solar-like stars, which is paramount to preparing PLATO.

description: By matching infrared-selected, massive young stellar objects (MYSOs) and compact HII regions in the RMS survey to massive clumps found in the submillimetre ATLASGAL survey, we have identified ~1000 embedded young massive stars between 280\degr < $\ell$ < 350\degr and 10degr < $\ell$ < 60\degr with |b|<1.5degr. Combined with an existing sample of radio-selected methanol masers and compact HII regions, the result is a catalogue of ~1700 massive stars embedded within ~1300 clumps located across the inner Galaxy, containing three observationally distinct subsamples, methanol-maser, MYSO and HII-region associations, covering the most important tracers of massive star formation, thought to represent key stages of evolution. We find that massive star formation is strongly correlated with the regions of highest column density in spherical, centrally condensed clumps. We find no significant differences between the three samples in clump structure or the relative location of the embedded stars, which suggests that the structure of a clump is set before the onset of star formation, and changes little as the embedded object evolves towards the main sequence. There is a strong linear correlation between clump mass and bolometric luminosity, with the most massive stars forming in the most massive clumps. We find that the MYSO and HII-region subsamples are likely to cover a similar range of evolutionary stages and that the majority are near the end of their main accretion phase. We find few infrared-bright MYSOs associated with the most massive clumps, probably due to very short pre-main sequence lifetimes in the most luminous sources.

Intelligent Control of a Quadrotor with Suspended Load
Creators: Mohammadhasani, Arash
Publisher: name: University of Alberta Library
Year: 2022

This thesis targets output tracking problem for payload position and quadrotor yaw in an slung load system (SLS). In spite of its relatively extensive literature, full SLS

control is still a challenging problem since its dimension, nonlinearity, and multiple sources of disturbances are not easy to handle using available nonlinear control tools. Based on the inherent property of SLS having a flat output, in this thesis, we

tried to solve the robust output tracking using tools from differential geometry and reinforcement learning (RL).

We first construct a control-affine model for SLS which is novel in that it is written in pendulum coordinates and considers disturbances in pendulum dynamics.

Our payload is modelled as a single pendulum attached to the center of mass (CoM) of the unmanned aerial vehicle (UAV) with a spherical joint. Based on this model, we use dynamic extension algorithm (DEA) to reformulate SLS dynamics so that

the derived system is feedback linearizable and yet complies with our original output tracking problem. Static state feedback linearization of the augmented system then

provides linear time-invariant (LTI) tracking error dynamics in the linearizing state coordinates. These dynamics are exponentially stable on a well-defined and practical

region of state space for constant disturbances. Moreover, we provide a Maple symbolic script which can be used to apply DEA to general nonlinear control-affine systems.

Finally, we employ ideas from RL to further robustify our proposed DEA-based control scheme against disturbances and to fill its weaknesses in model dependency.

We cover all required definitions and algorithms and highlight what distinguishes the proposed approach from conventional RL-based control. Closed-loop performance is validated in simulation and compared with a state-of-the-art method from the literature.

description: Responses of neurons in monkey visual cortex are modulated when attention is directed into the receptive field of the neuron: the gain or sensitivity of the response is increased or the synchronization of the spikes to the local field potential (LFP) is increased. We investigated, using model simulations, whether the synchrony of inhibitory networks could link these observations. We found that, indeed, an increase in inhibitory synchrony could enhance the coherence of the model neurons with the simulated LFP, and could have different effects on the firing rate. When the firing rate vs. current (f–I) response curves saturated at high I, attention yielded a shift in sensitivity; alternatively, when the f–I curves were non-saturating, the most significant effect was on the gain of the response. This suggests that attention may act through changes in the synchrony of inhibitory networks.

Development of a Waste Rock Simulation Model Including Placement Techniques to Minimize Environmental Impacts of Acid Rock Drainage
Creators: Hurtubise, Rebecca R
Publisher: name: University of Alberta Library
Year: 2022

This research aims to develop a model using a systems dynamics approach that can be coupled with TMSim to account for the deposition of waste rock at hard rock mines at the feasibility stage of mine planning. The model includes waste rock placement techniques to minimize the environmental impacts of acid rock drainage at many hard rock mines. The GoldSim software was used to develop the model, with two aspects, the deposition of waste rock based on mine processes to create the “pile”, and the environmental conditions and associated variably saturated flow of water within the waste rock pile.The conceptualization of the waste rock in the pile was constructed in four lifts. These four lifts were divided into 15 rows and 16 columns to create a pseudo 3-D structure of 240 1-D columns. The model includes waste rock deposition, precipitation, snowmelt, evaporation, runoff, infiltration, and seepage. The variably saturated system was modelled using a modified version of the variably saturated flow sub-model for a tailings cover. Modifications of the model included potential evaporation calculation, snow accumulation and meltwater calculation, and simplification of runoff. The model was run using a case study for a mine site at the feasibility stage to demonstrate the application of the model. Overall, the model behaved as expected with general pile water balance behaviour observed over the course of construction and long-term behaviour. The models clearly show the benefits of paddock dumping versus end dumping with reduced water storage volumes within the pile.

description: We prove that the residual girth of any finitely generated linear group is at most exponential. This means that the smallest finite quotient in which the $n$-ball injects has at most exponential size. If the group is also not virtually nilpotent, it follows that the residual girth is precisely exponential.
