description: The electrochemical CO2 reduction reaction (eCO2RR) is a scalable, flexible, compact, and energy-efficient route to convert CO2 into value-added products. However, the viability of eCO2RR relies on reducing energy demands and production costs to compete with established alternatives. Integration of CO2 capture and conversion, where the capture system is unified with eCO2RR, has the potential to eliminate energy-intensive steps of CO2 capture and regeneration, leading to improved process economics. The first part of this study conducted a comprehensive review of available literature to identify the potential sources of CO2 and the relevant capture technologies. The second part focuses on using ambient air to capture CO2 using direct air capture (DAC) technology using alkali-hydroxide-based solvent to produce carbonate and converting carbonate into an electrochemical system. The concept of carbonate electrolysis was explored as a method for regenerating the capture solvent while converting CO2 to carbon monoxide (CO). It was found that the electrochemical cell could serve as both a solvent regeneration and CO2 conversion step. Our modeling study showed a trade-off between the regeneration and CO2 conversion step. However, the techno-economic analysis (TEA) showed that with technological advancements, the production cost of CO could drop below 200 $/ton CO compared to the current production cost over 1500 $/ton CO. The third chapter focused the on direct electrolysis of CO2 from a dilute stream to simulate industrial flue gasses. A permselective gas diffusion electrode (PGDE) consisting of a metal-organic framework-based permselective layer and a silver-based gas diffusion electrode (GDE) was designed. The PGDE enables in-situ CO2 capture and electrochemical conversion. A comparative study of various PGDEs was performed to find the optimum conditions. With 10% CO2 purity in the feedstock, the CALF-20/PSF-based PGDE delivered a 5-fold increased maximum partial current density compared to the unmodified GDE. In addition, it was able to perform continuously for more than 20 hours and retained around 70% FE for CO. In conclusion, this thesis provides an understanding of the efficiency trade-off between CO2 capture and conversion and identifies pathways for optimizing efficiency. The integration of CO2 capture and conversion reduces the need for energy-intensive steps and has the potential to lower the production costs of CO2 derived chemical feedstocks.

On the estimation of the polychoric correlation coefficient via Markov Chain Monte Carlo methods
Creators: name: Olvera Astivia, Oscar Lorenzo
Publisher: name: University of British Columbia
Year: 2013

description: Bayesian statistics is an alternative approach to traditional frequentist statistics that is rapidly gaining adherents across different scientific fields. Although initially only accessible to statisticians or mathematically-sophisticated data analysts, advances in modern computational power are helping to make this new paradigm approachable to the everyday researcher and this dissemination is helping open doors to problems that have remained unsolvable or whose solution was extremely complicated through the use of classical statistics. In spite of this, many researchers in the behavioural or educational sciences are either unaware of this new approach or just vaguely familiar with some of its basic tenets. The primary purpose of this thesis is to take a well-known problem in psychometrics, the estimation of the polychoric correlation coefficient, and solve it using Bayesian statistics through the method developed by Albert (1992). Through the use of computer simulations this method is compared to traditional maximum likelihood estimation across various sample sizes, skewness levels and numbers of discretisation points for the latent variable, highlighting the cases where the Bayesian approach is superior, inferior or equally effective to the maximum likelihood approach. Another issue that is investigated is a sensitivity analysis of sorts of the prior probability distributions where a skewed (bivariate log-normal) and symmetric (bivariate normal) priors are used to calculate the polychoric correlation coefficient when feeding them data with varying degrees of skewness, helping demonstrate to the reader how does changing the prior distribution for certain kinds of data helps or hinders the estimation process. The most important results of these studies are discussed as well as future implications for the use of Bayesian statistics in psychometrics

description: It has been recently shown that the relative velocity between the dark matter and the baryons (vbc) at the time of recombination can affect the structure formation in the early universe (Tseliakhovich & Hirata 2010). We statistically quantify this effect using large cosmological simulations. We use three different high resolution sets of simulations (with separate transfer functions for baryons and dark matter) that vary in box size, particle number, and the value of the relative velocity between dark matter and baryons. We show that the total number density of halos is suppressed by ~ 20% at z = 25 for vbc = 1σ(vbc), where σ(vbc) is the variance of the relative velocity, while for vbc = 3.4σ(vbc) the relative suppression at the same redshift reaches 50%, remaining at or above the 30% level all the way to z = 11. We also find high abundance of "empty halos", i.e., halos that have gas fraction below half of the cosmic mean baryonic fraction fb. Specifically we find that for vbc = 1σ(vbc) all halos below 10^5M\odot are empty at z \geq 19. The high abundance of empty halos results in significant delay in the formation of gas rich mini-halos and the first galaxies.

description: The smoothelin-like 1 (SMTNL1) protein is a regulator of vascular homeostasis, wherein it modulates smooth muscle contraction, myogenic response, endothelial barrier function, and inflammatory responses. Vascular function is known to reciprocally influence cardiac function, with impaired diastole and left ventricular (LV) stiffness causally linked to endothelial dysfunction and coronary microvascular inflammation. SMTNL1, also highly expressed in skeletal muscle, can impact the energy metabolism and insulin sensitivity of female mice during pregnancy. Therefore, I investigated the metabolic and cardiac outcome in a mouse model deficient in SMTNL1 with advancing age. The cardiac function of SMTNL1 global knockout (KO) mice (3-, 12- and 18-month-old, male and female) was assessed by echocardiography and pressure-volume loop, and the metabolic measurements of middle-aged animals (12-month-old, male and female) were carried out in the comprehensive lab animal monitoring system (CLAMS). The cardiac hemodynamic profiling showed that young male SMTNL1 KO mice developed hypertension and diastolic dysfunction as evidenced by increased systolic blood pressure, end diastolic pressure, LV relaxation time constant (tau), and steeper end diastolic pressure-volume relationship. Unlike young males, the 3-month-old female KO mice did not develop diastolic dysfunction. However, ageing elicited progressive impairment of diastolic function in female KO mice with reduced LV diastolic compliance and elevated filling pressures in comparison to their wild-type counterparts, along with a preserved systolic function in all age groups. Furthermore, flow-mediated dilation, an index of endothelial function was impaired in both male and female KO cohorts at 12 months age, the endocrinal equivalent of human menopausal age. Ageing was also associated with altered cardiac morphology and fibrotic levels along with energy imbalance and glucose intolerance with the loss of SMTNL1. Collectively, the study identified pathophysiological effects of SMTNL1 deletion on metabolic, vascular, and diastolic function with increasing age in a sex-dependent manner. The SMTNL1 KO model for the first time recapitulates the sex dimorphic onset of diastolic dysfunction that is central to heart failure with preserved ejection fraction (HFpEF) condition and represents a novel preclinical model with comorbidities to study the etiology of the HFpEF clinical phenotype.

description: The Lya emission has been observed from galaxies over a redshift span z ~ 0 - 8.6. However, the evolution of high-redshift Lya emitters (LAEs), and the link between these populations and local galaxies, remain poorly understood. Here, we investigate the Lya properties of progenitors of a local L* galaxy by combining cosmological hydrodynamic simulations with three-dimensional radiative transfer calculations using the new ART^2 code. We find that the main progenitor (the most massive one) of a Milky Way-like galaxy has a number of Lya properties close to those of observed LAEs at z ~ 2 - 6, but most of the fainter ones appear to fall below the detection limits of current surveys. The Lya photon escape fraction depends sensitively on a number of physical properties of the galaxy, such as mass, star formation rate, and metallicity, as well as galaxy morphology and orientation. Moreover, we find that high-redshift LAEs show blue-shifted Lya line profiles characteristic of gas inflow, and that the Lya emission by excitation cooling increases with redshift, and becomes dominant at z > 6. Our results suggest that some observed LAEs at z ~ 2-6 with luminosity of L_Lya ~ 10^{42-43} ergs/s may be similar to the main progenitor of the Milky Way at high redshift, and that they may evolve into present-day L* galaxies.

description: We present RIXS data at O K edge from La2-xSrxCuO4 vs. doping between x=0.10 and x=0.22 with attention to the magnetic excitations in the Mid-Infrared region. The sampling done by RIXS is the same as in the undoped cuprates provided the excitation is at the first pre-peak induced by doping. Note that this excitation energy is about 1.5 eV lower than that needed to see bimagnons in the parent compound. This approach allows the study of the upper region of the bimagnon continuum around 450 meV within about one third of the Brilluoin Zone around Γ. The results show the presence of damped bimagnons and of higher even order spin excitations with almost constant spectral weight at all the dopings explored here. The implications on high Tc studies are briefly addressed.

description: Aggressive behavior is common on psychiatry inpatient units (Bonner et al., 2002). Seclusion rooms and restraints used as interventions for patients’ aggressive behaviour may have the consequence of being traumatizing for patients (O’Brien & Cole, 2004). The voices of many stakeholders involved in the controversial conversation of the use of seclusion and restraint interventions are represented in the literature. In pediatric psychiatry, however, the voices of the children are not represented, even though they hold the most vulnerable position with the most at stake in the practice of seclusion and restraint interventions for aggression management. This hermeneutic nursing research study asked the question “How might we understand children’s experiences of seclusion and restraint on an inpatient psychiatry unit?”. Four pediatric psychiatry inpatients responded to the invitation to be research participants and shared their hospitalization experiences that occurred within the past year when they were 10 years old. Their interviews lead to the interpretation of the importance of nursing discernment in decision making upon the entrance to each room that holds a patient, physically and metaphorically, to ensure the most therapeutic, ethical, and beneficial care is provided to the patient. The text of the research interviews was compared to the theories and models of Attachment Theory (Bowlby, 1980), Trauma Informed Care (Harris & Fallot, 2001), and Collaborative Problem Solving (Greene, 2014) for practical application, and the fairy tale of Hansel and Gretel (The Brothers Grimm, 1812) for a historical illustration of the relevant social-cultural issue regarding the maltreatment of children that continues to resonate today.

description: Academic achievement is an important part of healthy development for children and adolescents because of its impact on mental health, wellbeing, and occupational success. Therefore, promoting academic achievement in students of all ages should be a central goal of educational programming. However, to do this, it is essential to first understand what, and how, different factors impact student achievement. Although there are a variety of variables that contribute to academic achievement, executive functioning (EF) and academic motivation and engagement appear to play particularly important roles. To further explore the relationships between academic achievement, motivation and engagement, and EF, two hierarchical multiple regressions were conducted on a sample of high school students. The Motivation and Engagement Scale – High School (MES-HS) was used to measure the positive and negative aspects of students’ motivation and engagement. The Executive Skills Questionnaire – Teen Version (ESQ-T) was used to measure students’ EF. Grade point average (GPA) was used to measure academic achievement. Regarding EF, only working memory and metacognition significantly predicted GPA. This suggests that, of all components of EF, these two are most strongly implicated in academic achievement for high school students. Regarding motivation and engagement, only positive engagement significantly predicted academic achievement for high school students. This suggests that positive engagement plays an important role in academic achievement for high school students.

description: Gut microbial dysbiosis is associated with increased susceptibility to infectious diseases, including systemic infection and sepsis. While the impact of the microbiota on intestinal homeostasis is well recognized, gut commensals also influence several processes in extraintestinal niches, including host defense against systemic infection. This thesis aimed to study the microbiota-immune interactions that promote host defense against bacterial sepsis at a cellular and molecular level. Using gnotobiotic mouse models and resonant scanning confocal intravital microscopy, I demonstrated that mice devoid of gut commensals show defective intravascular immune responses against staphylococcal sepsis. In germ-free mice, impaired Kupffer cell-mediated bacterial capture and neutrophil trafficking in the liver contribute to increased bacterial dissemination and host mortality. Gut microbiota-dependent regulation of intravascular immunity is dynamic and partly rescued by replenishing gut-derived D-lactate, indicating this bacterial metabolite mediates the crosstalk between the gut microbiota and the liver microenvironment. D-lactate enhances bacterial clearance by Kupffer cells and primes the liver endothelium to respond robustly to inflammatory stimuli, leading to increased neutrophil adherence after infection. Altogether, this thesis uncovers a line of communication between the gut microbiota and the liver microenvironment that is pivotal for intravascular immune defense against sepsis.

description: We study optical excitations across the Mott gap in the multi-orbital Mott-Hubbard insulators RVO3. The multi-peak structure observed in the optical conductivity can be described consistently in terms of the different 3d^3 multiplets or upper Hubbard bands. The spectral weight is very sensitive to nearest-neighbor spin-spin and orbital-orbital correlations and thus shows a pronounced dependence on both temperature and polarization. Comparison with theoretical predictions based on either rigid orbital order or strong orbital fluctuations clearly rules out the latter. Both, the line shape and the temperature dependence give clear evidence for the importance of excitonic effects.

Determining the impacts of hydrological drought on endangered Nooksack dace (Rhinichthys cataractae) at the population and individual level : Implications for minimum environmental flow requirements
Creators: name: Avery-Gomm, Stephanie
Publisher: name: University of British Columbia
Year: 2013

description: Understanding the impacts of hydrological drought is crucial to the conservation of freshwater fishes. In British Columbia, Nooksack dace (Cyprinidae: Rhinichthys cataractae) are an endangered riffle specialist and are threatened by extremely low summer flows. The purpose of this thesis was to explore the impacts of drought on Nooksack dace, whether pool habitats may act as refugia to mitigate these impacts, and to define minimum environmental flow requirements. The first two objectives were addressed using a combination of field survey and experimental manipulations. A reduction in Nooksack dace population size with declining summer flow in Bertrand Creek, and a marked decrease in growth at low discharge in experimental riffles, indicated that low discharge has negative impacts on dace at both population and individual levels. Pool habitats were found to play a minor role in mitigating the negative impacts of hydrological drought (e.g., decreased growth rate), save as a refuge from stranding when riffles dewater. The third objective was addressed using the Instream Flow Incremental Methodology (IFIM). Because this study involved an endangered species an emphasis was placed on evaluating two fundamental assumptions of the methodology. Experimental results for Nooksack dace growth at different depths and velocities provided support for the first assumption, that density-based Habitat Suitability Curves (HSCs) accurately reflect habitat quality, but only for the lower limits of the HSCs. Next, a significant positive relationship between Weighted Usable Area (WUA) and dace biomass was found, supporting the assumption that such a relationship exists. However, this relationship was weak indicating a high degree of uncertainty in how Nooksack dace biomass will respond at high discharges. The IFIM model predicted that habitat availability for Nooksack dace begins to decline most rapidly at discharges of 0.12 m³.s-¹. As there is low confidence in upper ranges of the HSCs this low flow threshold may underestimate declines with discharge, and therefore protection of at least 0.12 m³.s-¹ is considered necessary for the persistence of Nooksack dace individuals and populations. Compared to conventional instream flow criteria, 0.12 m³.s-¹ represents ~10% mean annual discharge which is the threshold for severely degraded habitat.
Towards High-Strength and Low-Carbon Concrete Masonry Blocks Using Locally Available Materials

Publisher: name: Graduate Studies

Subjects: subject: Engineering--Civil

description: High-strength concrete masonry blocks are attracting attention to be used for loadbearing applications, such as tall walls. Such blocks can be achieved via modification of the dry mixture design and production methods. These modifications, however, may increase the carbon footprint of the concrete masonry blocks upon manufacturing. Careful selection of the mixture parameters is, therefore, necessary for the production of concrete blocks that have higher compressive strengths yet low carbon footprints. This study explored the effectiveness of using locally available materials for the production of dry concrete mixtures that can be used for the masonry block manufacturing. First, the suitability of utilizing pumice, sourced in British Columbia, as an alternative for Class F fly ash to partially replace the Portland cement in the concrete mixtures was studied. That was important as the availability of Class F fly ash is declining in Alberta and finding alternative replacements is imperative. To overcome the lower reactivity and strength development of pumice, a performance enhancing chemical admixture was used. Finally, recycled aggregates were obtained by crushing and pulverizing concrete masonry blocks that were used for structural testing in the laboratory. The so-produced aggregates were used as a replacement for the natural aggregates in the production of the dry concrete mixtures without and with pumice and chemical admixture. The resulting dry concrete mixtures were categorized into different classes of 30, 35, 40, and 50 MPa based on their average compressive strength at the age of 28 days in the laboratory conditions. Their mixture proportion with respect to their cement intensity (cement content per unit of strength) and application was discussed, and recommendations for future research were made. It is worth noting that although the results of this study were obtained for producing dry concrete mixtures, they can be extended for other concrete applications.
Stability and evolution of wave packets in strongly coupled degenerate plasmas

Year: 2011

description: We study the nonlinear propagation of electrostatic wave packets in a collisional plasma composed of strongly coupled ions and relativistically degenerate electrons. The equilibrium of ions is maintained by an effective temperature associated with their strong coupling, whereas that of electrons is provided by the relativistic degeneracy pressure. Using a multiple scale technique, a (3+1)-dimensional coupled set of nonlinear Schrödinger-like equations with nonlocal nonlinearity is derived from a generalized viscoelastic hydrodynamic model. These coupled equations, which govern the dynamics of wave packets, are used to study the oblique modulational instability of a Stoke's wave train to a small plane wave perturbation. We show that the wave packets, though stable to the parallel modulation, becomes unstable against oblique modulations. In contrast to the long-wavelength carrier modes, the wave packets with short-wavelengths are shown to be stable in the weakly relativistic case, whereas they can be stable or unstable in the ultra-relativistic limit. Numerical simulation of the coupled equations reveals that a steady state solution of the wave amplitude exists together with the formation of a localized structure in (2+1) dimensions. However, in the (3+1)-dimensional evolution, a Gaussian wave beam self-focuses after interaction and blows up in a finite time. The latter is, however, arrested when the dispersion predominates over the nonlinearities. This occurs when the Coulomb coupling strength is higher or a choice of obliqueness of modulation, or a wavelength of excitation is different. Possible application of our results to the interior as well as in an outer mantle of white dwarfs are discussed.

description: The development of sustainable methods to transform biomass into value-added products is crucial to realize the circular bioeconomy and mitigate the happening climate change. Photocatalysis and biocatalysis have emerged as two such methods in recent years. However, there are some significant obstacles for each one of them. Recently, inspired by the process of photosynthesis in nature, enzyme-photocatalyst-coupled systems (EPCSs) based on Nicotinamide adenine dinucleotide, reduced (NADH) has offered a new method that could potentially mitigate the drawbacks of each one of these methods and yield interesting synergy. In this study, we indicate the huge potential of zinc-blende (ZB) CdS as an outstanding catalyst for NADH regeneration in EPCSs with a rate of 13.1 mM/h, the highest reported in the literature, to the best of our knowledge. The catalyst shows decent stability for repeated cycles. In the second part, we report for the first time, the photoenzymatic reduction of levulinic acid, a major platform chemical derived from biomass. This serves as an example to expand the reaction spectrum of EPCSs based on NADH to enzymes and reactions beyond those that are frequently used. Almost 4 mM of levulinic acid could be reduced within 3 hours using the EPCS. During the course of this study, we also examined the importance of the sacrificial electron donor (SED) in the EPCSs, for the first time, and showed that our catalyst can accept various chemicals, especially glycerol, as SED. Besides, we report some unprecedented cross-inhibitory effects between SED and the enzyme which should be considered for future studies.

description: We study how the recent ATLAS and CMS Higgs mass bounds affect the renormalization group running of the physical parameters in universal extra dimensions. Using the running of the Higgs self-coupling constant, we derive bounds on the cutoff scale of the extra-dimensional theory itself. We show that the running of physical parameters, such as the fermion masses and the CKM mixing matrix, is significantly restricted by these bounds. In particular, we find that the running of the gauge couplings cannot be sufficient to allow gauge unification at the cutoff scale.

description: Osmostasis relies on the efficient and selective transport of molecules across barriers, often in a directional manner and this, in turn, is dependent on the asymmetric arrangement of channels within the cells comprising the organs that regulate these processes. The primary aim of this thesis is the identification of the extracellular matrix-receptor interactions important in the generation of polarized channel distribution in two such organs, the kidney and the blood-brain barrier. In the first study, we investigated the involvement of fibronectin and laminin in the basolateral localization of Kir4.1, an inwardly-rectifying potassium channel, and aquaporin-4 (AQP4), a water-permeable channel, in polarized Madin-Darby canine kidney (MDCK) cells. We determined using a variety of approaches that laminin-1 and fibronectin, when present in the culture substrate, significantly stablize both channel types at the basolateral surfaces of these cells and accordingly induce their increased expression within this membrane domain without requiring a concomitant upregulation of de novo channel synthesis. We also show that the coexpressed laminin receptor dystroglycan (DG) is important for cell surface expression of Kir4.1 but not AQP4, and demonstrate via the use of disintegrin peptides and function-blocking antibodies that their cell-surface expression and stability is also partly reliant on integrin receptors, with αvβ3 being particularly important in the case of the latter. In the second study, we examined the possibility that laminin-dystroglycan binding is involved in the regulation of AQP4 turnover in astrocytes. We first determined that laminin, when applied to primary astrocytes in culture, causes AQP4 amounts at the plasma membrane to increase in a DG-dependent manner while depleting the channel from intracellular sites, brought about by the suppression of channel endocytosis. We then showed that DG binds to inactive dynamin, and that the latter, when freed from this inhibitory influence, functions in cooperation with clathrin to mediate the rapid internalization of AQP4. Finally, we demonstrated that laminin selectively upregulates the cell-surface expression of the M23 isoform of AQP4 only. Our findings therefore reveal that, through their roles in establishing the microscopic architecture of these systems, the extracellular matrix and cell-surface receptors are critical determinants in osmoregulation

description: We construct a special type of antichain (i. e., a family of subsets of a set, such that no subset is contained in another) using group-theoretical considerations, and obtain an upper bound on the cardinality of such an antichain. We apply the result to bound the number of strong counterpoint dichotomies up to affine isomorphisms.

description: The microbiome has a significant impact on immune health and response to immune-stimulating treatments, including cancer immunotherapy. However, the molecular mechanisms by which commensal microbes influence cancer immunology remain poorly understood. Here, we report on the discovery of a class of microbiome-derived metabolites called hydroxyphenyl propanoates (HPPs) that enhance tumour immune surveillance in mice and synergize with immune checkpoint blockade (ICB) therapy. HPP molecules act as broad spectrum potentiators of innate immune signalling pathways in tumour-associated myeloid cells by promoting cleavage of the pore-forming protein gasdermin D (GSDMD), a critical effector of canonical and non-canonical inflammasome signalling. Heightened secretion of proinflammatory cytokines from HPP-treated myeloid cells, including IL-1β, promotes NF-κB activity within tumour-infiltrating leukocytes. This leads to improved anticancer CD8 T cell function, significant tumour regression, and better long-term cancer control by immune checkpoint therapy in mice. Human peripheral blood mononuclear cells respond to HPP treatment in a similar way. GSDMD cleavage also associates with a favourable response to ICB therapy in advanced stage melanoma patients. Taken together, our study uncovers a previously unknown mechanism of microbiome-mediated modulation of host antitumour immunity that is modifiable and can be harnessed to enhance the efficacy of cancer immunotherapy.

description: We study the properties of spin systems realized by cold polar molecules interacting via dipole-dipole interactions in two dimensions. Using a spin wave theory, that allows for the full treatment of the characteristic long-distance tail of the dipolar interaction, we find several anomalous features in the ground state correlations and the spin wave excitation spectrum, which are absent in their counterparts with short range interaction. The most striking consequence is the existence of true long-range order at finite temperature for a two-dimensional phase with a broken U(1) symmetry.

description: Background Improved cardiovascular disease outcomes and reduced mortality are associated with optimal fitness and optimal psychological wellbeing (PWB). Women with obesity are at risk for having lower fitness levels and lower PWB attributed, in part, to weight stigmatization. A deeper understanding of how obesity impacts both fitness and PWB in women is required. Methods Methods for three manuscripts include: a retrospective analysis of cardiorespiratory fitness (CFR) in women with differing BMI categories, following cardiac rehabilitation (CR), a scoping review synthesizing what is known about PWB in women with obesity, and a web-based survey examining relationships between general health, internalized weight bias (IWB), BMI and multiple constructs of PWB in a sample of community dwelling women. Results Women with obesity (BMI>30 kg/m2) had smaller gains in CRF (standard mean difference =0.79, p=.028; n=398), relative to women in the normal (BMI between 18.5 to 24.99 kg/m2) and overweight (BMI between 25.00-29.99 kg/m2) categories (SMD=1.03, n=454 and 0.92, n=461 respectively, p values<.001). Findings from thirty-two studies with over 57,000 women with obesity revealed women with obesity rated their PWB lower than women without obesity. However, this relationship was attenuated when self-health, body satisfaction, and social factors were included in the statistical model. In a survey of 1001 community dwelling women, those with obesity rated their positive emotions (p<.001), engagement (p=.007), relationships (p<.001) sense of meaning (p<.001) and accomplishments (p<.001) (acronym: PERMA), happiness (p<.001), and health (p<.001) lower and their IWB higher (p<.001) than women without obesity. Health accounted for up to 22% of the variance in PERMA and happiness scores whereas BMI and IWB contributed to 1-6% of the variance. Conclusion Women with obesity had lower fitness levels, smaller improvements in exercise capacity (METS) in CR, and generally lower PWB compared to women without obesity. This research offered initial insights into a complex relationship between fitness, health, IWB, BMI, and PERMA and happiness in women with obesity. This research highlights an opportunity to explore the causes of these differences, target interventions to improve exercise capacity, and determine how positive psychological interventions could be used as a psychological resource to support women with obesity.

description: ArgoNeuT, or Argon Neutrino Test, is a 170 liter liquid argon time projection chamber designed to collect neutrino interactions from the NuMI beam at Fermi National Accelerator Laboratory. ArgoNeuT operated in the NuMI low-energy beam line directly upstream of the MINOS Near Detector from September 2009 to February 2010, during which thousands of neutrino and antineutrino events were collected. The MINOS Near Detector was used to measure muons downstream of ArgoNeuT. Though ArgoNeuT is primarily an R&D project, the data collected provide a unique opportunity to measure neutrino cross sections in the 0.1-10 GeV energy range. Fully reconstructing the muon from these interactions is imperative for these measurements. This paper focuses on the complete kinematic reconstruction of neutrino-induced through-going muons tracks. Analysis of this high statistics sample of minimum ionizing tracks demonstrates the reliability of the geometric and calorimetric reconstruction in the ArgoNeuT detector.
