abstract:
The Purkinje system is the conduction network of the heart that facilitates coordinated ventricular contraction and couples to the myocardium at discrete sites called Purkinje-Myocyte Junctions (PMJs). Fine and intricate geometry of the Purkinje system have confined experimental observations, therefore density and distribution of PMJs and Purkinje system contribution during cardiac arrhythmia are unclear. This thesis presents a detailed computer simulation study that highlights the role of the Purkinje system and its interaction with ventricles in arrhythmogenesis and maintenance.
Firstly,  simulations were performed on a model of rabbit ventricles to explore Purkinje system contributions during ventricular fibrillation. A fractal method for growing the Purkinje system was implemented  to allow construction of anatomically realistic Purkinje network and investigation of PMJ density. The role of the Purkinje system in maintaining the arrhythmia was assessed by analyzing reentry dynamics. Results showed that the activation pattern at PMJs had little consistency over time during functional reentry, and a Purkinje system with a higher PMJ density
contributed more to reentrant arrhythmia; however, the overall  dynamics of sustained reentry did not appear to be  significantly affected by Purkinje system complexity and coupling strengths at PMJs. Secondly, the realistic model of the Purkinje system was used to investigate mechanisms through which reduced myocardial coupling, induced by ischemia, modify  the interaction between the Purkinje system and ventricular tissue, and affect ventricular excitation pattern. Experimental and modeling results suggest that ischemia-induced closing of
gap junctions  activates normally quiescent PMJs due to reduced source-sink mismatch and as a result, increased the complexity of activation. Modeling results indicated that a higher number of functional PMJs can speed activation of tissue and compensate for effects of uncoupling in slowing activation of the ventricles. Finally, effects of a potential antiarrhythmic drug, dantrolene,  on suppressing  delayed afterdepolarizations (DADs) due to Calcium overload were modeled. In ventricular model, rapid pacing promoted triggered activity but only those arising in the Purkinje fibers could generate action potential that propagated throughout the myocardium. According to modeling results, dantrolene could eliminate DAD at the Purkinje level by blocking channels that are only present in the Purkinje system.

abstract: This project is concerned with figuring out under what conditions addiction serves as an excuse from blame. The first chapter argues that addicts have diminished control over their drug use. Chapter 2 develops the ethical framework that I will use to approach the question. Chapter 3 argues that addiction does not undermine moral responsibility. The upshot of this is that if addiction is excusing, it is not because addicts are the kinds of people who cannot serve as subjects for blame. Chapter 4 offers and defends a different account of addiction as an excuse, which holds that addiction is excusing for people with a certain kind of character and a certain kind of history. It also illustrates the practical application of my account and points to an important outstanding problem for future research.

abstract: The NOD-like Receptors (NLRs) are a family of pattern recognition receptors known to regulate a variety of immune signaling pathways. A substantial portion of NLR research focuses on the pyrin domain-containing NLRP subfamily. The canonical NLRPs are inflammasome-forming proteins responsible for the activation of caspase-1 and the maturation and secretion of the pro-inflammatory cytokines IL-1β and IL-18. In contrast, the non-canonical inflammasome-independent NLRPs regulate a variety of other pathways, including MAPK and NF-κB, through the formation of non-inflammasome complexes. Interestingly, not all inflammasomes are nucleated by NLRPs. The recently characterized non-canonical caspase-4 (caspase-11 in mice) inflammasome is known to be a key driver of the innate immune response to intracellular pathogens (and the molecules associated with them), by triggering both inflammatory cell death and the activation of canonical inflammasomes.  At the outset of this PhD work, the understanding of both non-inflammasome-forming NLRPs and the non-canonical caspase-4 inflammasome was poor and the studies were sparse. It was the goal of this thesis to characterize the expression, gene regulation, and function of the non-inflammasome-forming NLR protein NLRP6, both at the cellular and biochemical level. Furthermore, using a pathogen-associated molecular pattern (PAMP)-driven model of inflammation, we sought to elucidate the function of the non-canonical caspase-4 inflammasome, particularly as it pertains to the regulation of the canonical inflammasome and cell death. By studying the fundamental biology underlying these lesser-known mediators of the innate immune system, we hoped to better understand their contribution to the early immune response and their role in driving inflammatory disease with a view to, one day, ameliorating the condition of patients suffering from these afflictions through the development of targeted therapeutics.

abstract: Studies have shown that though there is a recent push to include computational thinking and coding in elementary schools, many elementary school teachers have no background in the subject and would require training to effectively teach computational thinking to their students. In this thesis, the development of a framework to train elementary school teachers and students in computational thinking is presented. It is based on a framework for engineering education, and modifies that framework to design and implement creative, cross-curricular activities to teach computational thinking and engineering concepts for students in grades K-6. The activities are also used in a professional development workshop to train teachers in these skills. These activities have positive impacts on perceptions of computational thinking for both elementary school teachers and their students, as evaluated by surveys and interview responses. As well, teachers felt more confident in their ability to implement similar activities in their classrooms.

abstract: I examined the relationship between selective habitat use and population genetic structure of black-and-white ruffed lemurs (Varecia variegata) in the fragmented Kianjavato- Vatovavy landscape in southeastem Madagascar. I calculated ranges for 17 lemurs in two forest fragments (June 2010 - March 2011, 4149 GPS points) and analysed the relationship between microhabitat characteristics and the probability of use of areas, and the extended use of trees within ranges. I genotyped 33 faecal samples for 16 microsatellites, adding 22 individuals from nearby continuous forest Ranomafana National Park. Despite the preferential use of large trees with broad crowns, low elevations, forest interiors, and areas with a large basal area of food species, it appears moderate fragment isolation (< lOOm) is insufficient to disrupt V variegata gene flow. However, larger distances (6km) isolated populations, leading to a population bottleneck and a drop in allelic richness. These results may inform reforestation and management efforts.

abstract: Background: A plethora of psychosocial predictors of Type 2 diabetes self-management adherence have been identified, yet these variables generally fail to account for more than about 25% of the variance in measures of diabetes adherence. The predominance of the Type 2 diabetes adherence literature represents behaviour change (intrapersonal) and social support (interpersonal) models. Few studies have examined the roles of empirically supported diabetes adherence predictors within a social-ecological model framework. Purpose: To use structural equation modeling to increase our understanding of the associations among social-ecological support resources, perceived locus of control of diabetes, negative affect (anxiety, depression, and alexithymia), and Type 2 diabetes self-care activities. Methods: This cross-sectional study utilized a convenience sample of 235 participants (54% male, 46% female) aged 25 to 87 (Mage= 56, SD = 11) with Type 2 diabetes from Calgary's Regional Diabetes Education Centre. Self-report measures were distributed for home completion and returned by post. Primary measures included (1) Chronic Illness Resources Survey, (2) Perceived Control of Diabetes Scales, (3) Twenty-Item Toronto Alexithymia Que tionnaire, (4) Well-Being Questionnaire anxiety and depression subscales, and (5) ummary of Diabetes Self-Care Activities Questionnaire, with an appended foot-care measure. Structural equation modeling was used to assess measurement and structural models. Results: Social-ecological support resources emerged as the sole direct predictor of diabetes self-care activity, accounting for 45% of the variance in diabetes self-care activity. Intraindividual variables ( decreased emotional well-being, perceived personal and situational control) had indirect effects on diabetes self-care activity primarily through their direct influence on social- 111 ecological support resources. Conclusions: The present study suggests that previous emphasis on the direct influence of intrapersonal variables measured in this study is likely an oversimplification of the complex interaction among variables influencing Type 2 diabetes self-care activities. Further, the results support a strong positive direct influence of utilization of social-ecological support resources on diabetes self-care activity, while the measured intrapersonal variables had only a very modest indirect relationship with diabetes self-care activity. Results point to the importance of considering social-ecological models of Type 2 diabetes adherence and ensuring sufficient availability and personal utilization of social-ecological support resources in clinical practice.

subject: Biomedical Colonoscopy Real-time Quality Assessment

abstract: Colonoscopy is the gold standard method for the diagnosis of colorectal cancer and the identification of precancerous polyps. Unfortunately, there is not yet a metric (formally recommended by consensus guidelines) for the quantification of colonoscopy quality. Though, there are established quality indicators such as the bowel preparation and the withdrawal time; fast withdrawal time is highly correlated with adenoma detection rate. Current metric tools for these parameters are not objective. This limitation leads to the formalization of the present study, which focuses on the development of a real-time, novel colonoscopy evaluation system and the assessment of its clinical efficacy. The proposed tool consists of an embedded system that can automatically measure: a) the quantity of stool and waste matter existing within the patient during a colonoscopy procedure; b) withdrawal velocity; c) image clarity; and d) determination of colonoscope direction and traveling distance. The proposed method can be used to create practice standards for colonoscopy training, or as part of medical skill evaluation.

subject: Architecture

abstract: Buildings are arguably more meaningfully approached as process versus product. We cannot decarbonize a part of this process (e.g., operation stage) and thereby claim such building(s) as ‘sustainable.’ A zero-carbon structure with no robust functional flexibility will become obsolete long before its physical life concludes. The present research reveals that robust sustainability resides at the nexus of durability, flexibility, and responsibility principles. The author suggests that such principles are not mutually exclusive nor incompatible with values of aesthetics and performance. Through the study of flexible architecture, particularly in residential projects, the present thesis establishes a novel multi-criteria decision-making framework for design projects. The theoretical framework, offering holistic and unified design criteria, corresponds to physical, functional, economic, technological, social, legal, and political facets that instigate and propel building. The methodological approach of the research follows three sequential stages: literature meta-analysis, a survey of experts, and case studies. Theory is evoked, including recent considerations of open building, holistic design, and systems thinking (Langston 2013, Sinclair 2009, 2015, 2016; Imam and Sinclair, 2018, 2020, 2021). Industry perceptions regarding environmental, social, and economic tenets of sustainable development are identified via a purposive survey with 69 architects and researchers. Seminal cases of eight (8) award-winning projects are drawn from regions with the highest reported current and projected floor area, illustrating agility concepts in design, legislative, and/or financial ethos. Case study data, together with the strategic literature review and survey, highlights leading themes, suggesting agile systems that are composed of four key characteristics: 1) diverse approaches and strategies that can learn (design intelligence), 2) the relationship among systems and sub-systems is nonlinear, 3) co-evolve with their environment, and 4) display emergent properties. The large-scale impact of climate change that is accelerating before our eyes, now complicated by the pandemic, calls us to be resilient and more open-ended in designing our built environment. Agility proves a compelling means to proffer more inclusive distributed decision-making structures appropriate for daunting and rapidly evolving realities of contemporary life. Agility is not optional - rather, it is essential to next iterations of responsive & responsible process, product, space, and place.

abstract: Video games are immensely popular in contemporary society, and it conveys explicit and implicit messages to the consumer. The author investigates the presence of gender portrayal and how the popular culture phenomenon League of Legends depict and represent women. The author analyzes its content, such as roles and appearances, to develop an understanding of its accuracies regarding femininity in the game, and to expand upon the general body of knowledge on video games. A literature review was conducted by the author analyzing the presence of gender in various forms of media (books, television etc.), and gender in video games, and how women are portrayed in them. As prior literature shows, women are underrepresented, stereotyped, and presented in a sexualized manner. The author contends that media including video games, have an impact on an individual’s identity, socializing them to imitate the content that they see in video games under the pretense that it is ‘normal’ and ‘the way it is’ in reality. As a result, the author draws on the theories posited by George Gerbner and Ann Swidler in order to explain the implications of their theories on socialization. The author then engages in a qualitative content analysis of the roles in the game, and twelve female characters or ‘champions’ in League of Legends to uncover any themes or patterns, in relation to their roles, personality traits, occupation, and appearances etc. In addition, the author briefly discusses the male characters in the game to understand if the results on the female characters were unique only to them and not the male characters. Results suggest that women were more likely to be placed in typically male-coded roles, such as leaders and protectors, but at the expense of being depicted in scantily-clad clothing and sexualized manners. Presented research reflect some of the conclusions drawn in previous studies, but opens the field of video games to more research topics regarding League of Legends as a case study. It is an evolving video game with new content added frequently, as a result, the game can be re-investigated to explore developments on gender representations of men and women.

abstract: In 2016, Alberta Health Services implemented the ICU Delirium Initiative in all intensive care units (ICUs) in Alberta. The ICU Delirium Initiative was based on the ABCDEF care bundle and recommended (A) appropriate pain management, (B) daily breaks in continuous sedation along with lowering mechanical ventilation support, (C) appropriate choices for sedation and pain control, (D) routine screening and management of delirium, (E) early mobilization and (F) engagement of family. The purpose of this thesis was to examine the effects of the ABCDEF delirium care bundle on patient-centred outcomes and processes of care among adults admitted to ICUs in Alberta. An interrupted time series analysis using retrospective linked clinical and administrative data from November 2014 to June 2019 was conducted in 14 adult general medical-surgical and one neurological ICU in Alberta. All patient admissions from each site were included after the site had transitioned to the current population-based electronic health documentation system. Provincial outcome trends were compared before and after the ICU Delirium Initiative was implemented in September 2016. The primary outcome was percent of delirium days per ICU. Secondary outcomes included: ever delirium, duration of mechanical ventilation, percent of coma days per ICU, percentage of sedation days using midazolam, adverse events and ICU length of stay and mortality. All outcomes were examined using mixed effects segmented linear regression with ICU site as the random effect. After the intervention, the overall percent of delirium days per ICU was 33.48% [95% Confidence Interval (CI) 29.64-37.31%] in January/February 2017 and decreased significantly by 0.34% every two months (95% CI 0.18-0.50%) following intervention implementation to a final estimate of 28.74% (95% CI 25.22-32.26%) in May/June 2019. The percentage of sedation days using midazolam decreased immediately following the intervention [decrease of 7.58% (95%CI 4.00-11.16%)]. Additionally, there were no significant changes in major adverse events (e.g., patient fall), minor adverse events (e.g., patient removal of peripheral intravenous), duration of mechanical ventilation, percentage of coma days per ICU or ICU mortality. These results suggest that population-based implementation of the ABCDEF bundle is feasible, effective, and safe.

abstract: Rigorous analytical techniques are combined with phylogeneticsystematic methodology to provide a new perspective on the scientific informativeness of the eggs and eggshells of both extant and extinct dinosaurs. Re-description of the eggs of paleognathous birds reveals that numerous eggshell characteristics were overlooked by previous investigators. A cladistic analysis of discrete egg characters of paleognaths reveals that although trees based on egg data provide less resolution among taxa than those based on skeletal data, egg data do provide phylogenetic information and can help resolve disagreements in relationships derived from skeletal data. In an analysis based on the egg data alone, tinamous are basal among paleognaths, Apteryx is basal among ratites and the sister taxon of an unresolved clade consisting of large ratites, within which Aepyornis and dinornithids form a subclade and Casuarius and Dromaius form a subclade. When the egg data are combined with the skeletal data of Bledsoe (1988), the clade of Apteryx, Casuarius, and Dromaius is dissolved, and Apteryx moves to a basal position within Ratitae. Analysis of 13 absolute measurements and ratios from the eggs reveals that only 4 of these continuous characters are suitable for cladistic analysis. A cladistic analysis of the continuous and discrete characters provides further resolution among taxa within the tree based on egg data in that Struthio and Rhea form a clade. Fossil eggs of several dinosaurs (including birds) are described and included in a cladistic analysis of 24 ootaxa, the results of which, in general, are comparable to those drawn from skeletal-based studies. Sauropod eggs are basal in Saurischia, allosauroid eggs are basal in Theropoda, the eggs of oviraptorids and dromaeosaurids form a derived clade, and the eggs of troodontids and birds form a clade. Unexpected results include the basal position of therizinosaurid eggs, a clade consisting of Protoceratopsidovum (Protoceratops eggs) and troodontid eggs, and a clade consisting of Deinonychus and oviraptorid eggs. These anomalies may call the alleged parentage of these eggs into question. The evolutionary-systematic method that was used to construct the traditional parataxonomic system for fossil eggs is eschewed, and a new nomenclatural system employing a phylogenetic-systematic methodology is proposed. Phylogenetic definitions are erected for seven ooclades of Saurischia, following the tenets of phylogenetic nomenclature.

abstract: It is becoming increasingly evident that major abatement strategies need to be implemented to tackle anthropogenic greenhouse gas (GHG) emissions. Balancing the expected growth of global energy demand while mitigating CO2 emissions is an urgent challenge of this century. With the growing interest in carbon capture and conversion technologies, there is a growing need to assess the economic feasibility and environmental benefit of these technologies. While broad deployment of carbon capture and sequestration (CCS) has significant potential for carbon mitigation, the potential value that can be created by utilizing the captured CO2 in a way that can create economic value, often referred to as carbon capture and utilization (CCU), is receiving growing momentum globally. Many proposals for CCU technologies assume that the capture and utilization facilities are geographically isolated, necessitating transport of captured CO2 and raising questions on the economic and environmental feasibility of the overall process. An alternative approach would be to develop an integrated process, wherein a utilization (i.e., conversion herein) process would likely be directly coupled with a compatible CO2 capture process, leading to in situ production of carbon-based fuels and feedstocks. In this context, high temperature fuel cell-based carbon capture technology (i.e., molten carbonate fuel cell or MCFC) offers an interesting opportunity, as it simultaneously produces electricity and concentrates CO2 (>96%) for subsequent utilization. Therefore, its is important to reveal the economic feasibility, environmental impacts and any trade-offs of an integrated carbon capture and utilization (CCU) for in situ production of fuels and chemicals. Here, we propose and subsequently assess an integrated electrochemical CCU process and compare with CCS route from economic and environmental aspects. This technoeconomic analysis reveals under baseline CCU scenario, carbon products reap either economic (67% and 10% gross margin increase for carbon monoxide and n-propanol, respectively) or environmental benefits (formic acid production would reduce ~721 thousand ton CO2e/year) relative to CCS route. Under optimistic scenario, while all the CO2 derived products are economically compelling over CCS route, only formic acid production would reduce ~1465 thousand ton CO2e/year over CCS (~575 thousand ton CO2e/year). This study may serve as a framework to decide whether a CCS or CCU pathway would be compelling under a given scenario when fuel cell-based CO2 capture technology is utilized to reduce carbon emissions and create economic value from fossil-based power plants.

abstract: Prenatal depression is a potentially debilitating experience that can affect both birthing parent and child. The current study investigates the role of cortisol, a hormone well-known for its involvement in the stress response, in the association between prenatal depression and child neurocognitive outcomes. Specifically, we assessed child executive function and cortical thickness in the right frontal and prefrontal cortices. Pregnant participants completed the Edinburgh Postnatal Depression Scale (EPDS) to assess prenatal depression, and we examined prenatal cortisol using salivary cortisol samples. Children completed six executive function tasks spanning the three domains of executive functioning and underwent magnetic resonance imaging to assess their cortical thickness. Our results indicate that prenatal depression during pregnancy, particularly early pregnancy, has the potential to adversely impact mental flexibility in children ages 3 – 4 years. Furthermore, an elevated prenatal cortisol awakening response (CAR) was related to timing-specific and region-specific cortical thinning in the right frontal cortex of children ages 3 – 7 years. Lastly, increased CAR in the third trimester was associated with better mental flexibility outcomes. Prenatal cortisol did not mediate the relationship between prenatal depression and child cortical thickness or executive function outcomes in our sample. Future research directions are discussed. Our study emphasizes the importance of caring for prenatal mental health in improving outcomes for child neurocognition.

abstract:
Reports show that 75% of the electricity demand of the whole United Arab Emirates comes from the buildings and that 70% goes into cooling (Supreme Council of Energy, 2014). Secondly, many modern buildings in the region have glazed glass façades. In line with the emirate's vision for sustainability 2021, Dubai Municipality (DM) Building Department prioritized the improvement of building efficiency. Buildings that have been constructed in the last 12 years have complied with the DM's minimum efficiency requirements. These included air conditioning equipment and thermal insulation for energy saving (Supreme Council of Energy, 2014). The Dubai Silicon Oasis
Authority (DSOA) is one of those complying with the energy saving requirements set by the DM Building Department. The DSOA headquarters building is, however, incurring high-energy cost that can be attributed to its cooling system.
The main goal of this study was to evaluate passive techniques to reduce cooling loads in multi-storeyed glass-façade commercial buildings. In recent years, Passive Cooling has found greater acceptance as an energy reducing measure across the world, as it is sustainable, economical, and is in alignment with the local natural resources. The effectiveness of each alternative cooling system depends on factors such as insulation, building design, orientation, etc. In addition, the applicable passive cooling techniques vary from region to region owing to variance in climate conditions and building material, local vegetation and climatic features. This study, therefore,
assessed which of these systems or strategies is appropriate for the Dubai Silicon Oasis Authority (DSOA) headquarters building as a case study and explored the principles of passive cooling techniques applicable to multi-storeyed buildings with glass façades. One wing (B) has been selected from the case study building. An Hourly Analysis Program, HAP, was used as a simulation tool in this research. Data of the studied building were collected and further analyzed by the said Program. The studied parameters were Air System Properties and Space Parameters.
Results showed that 18% saving in the cooling load of the seventh floor could be achieved by installing a green roof with a U-value glass of 0.7 W/m2K. This saving figure can be obtained from the other typical floors.

abstract:
Chronic medical conditions such as diabetes, hypertension, and heart disease are common in Canada and often occur together. Despite the availability of effective treatments, many Canadians do not receive optimal care for these conditions. This may be due to a number of factors, including reduced access to health services. The overall objective of this thesis was to improve knowledge of barriers to care and their association with adverse outcomes among patients with chronic disease.

We conducted three independent studies to address this objective. Our first study provides a national perspective on the potential gaps in care for Canadians with chronic disease. Using population-based survey data we found that 1 in 7 adults with chronic disease report a perceived unmet health care need – a commonly used indicator of limited access to care. Participants with multiple chronic conditions (multi-morbidity) were more likely to report a barrier to care. Furthermore, the most commonly reported reasons for an unmet need were related to service wait times and resource availability. By linking national survey and administrative data, our second study explored whether these perceived barriers to care were associated with adverse health outcomes. Unmet health care need was not associated with an increased risk of hospitalization when studied in aggregate form. However, when stratified by unmet need type, adults reporting barriers related to resource availability had an increased risk of all-cause hospitalization compared to those without. Our final study examined factors related to health system use and their association with adverse outcomes. Using provincial administrative data, specific patterns of health resource use and discharge disposition were associated with increased risk of subsequent hospitalization after discharge among patients with diabetes.

Despite a universal health care system, gaps in care for patients with chronic medical conditions remain. Although our findings highlight a number of potentially modifiable gaps in chronic disease care, further understanding of the concept of unmet health care need and the various factors that influence it are required. This may inform areas for future intervention aimed at enhancing and improving management for those living with chronic medical conditions.

abstract: The nutritional quality of foods is one important feature of habitat quality. For folivores, the protein-to-fiber ratio is a reliable predictor of food selection and folivore biomass and allows for comparisons between forests. I analyzed the nutritional quality of mature leaves eaten by Colobus vellerosus in three forests. This study fits well with previous research and there was a correlation between feeding time and the protein-to-fiber ratio. Surprisingly we found that food, nonfood, deciduous, evergreen, pioneer, and nonpioneer species had similar nutrient profiles. Seasonality and leaf longevity may have an overriding influence on leaf quality. Additionally, plants allocated nutrients evenly throughout plant parts because of their deciduous phenology pattern. Differences between forests were variable and may have been the result of ecological disturbance or soil quality. From a conservation perspective, nutritional studies allow us to assess the population viability of primates that are living in increasingly fragmented habitats.

abstract: One of the ways to dispose of spent carbon-based catalysts is gasification. In this study, the kinetics of CO2 gasification of Ni/activated carbon (AC) catalysts, produced from petroleum coke, were investigated at 700-900 °C using a thermogravimetric analyzer (TGA). The catalysts were coked by exposure to ethylene at 400-600 °C and/or impregnated with ~3.5 and 8.5 wt% vanadium, which is typically deposited during hydrodemetalization (HDM) of heavy oil. The gasification rates of all samples were 30-400 times greater than the rate of gasification of uncatalyzed (i.e., no metal) AC. Rate profiles as a function of conversion were different for all samples, which suggested that nickel was promoted/inhibited as a gasification catalyst in different ways depending on the composition of the sample. Transmission electron microscopy was used to analyze samples before and after gasification. The particle morphologies and chemical analysis (energy dispersive X-ray) help to explain the different gasification behaviours. In particular, the nickel particles on the coked Ni/AC sample became encapsulated by graphite and sintered over time from 20 nm initially to 150 nm after 80% conversion (~10 min at 900 °C). After preparation at 500 °C, the AC support was decorated with ~10 nm nickel particles and wetted with a layer of vanadium. After heating to 900 °C, however, sintering of both metals was evident as well as the formation of new vanadium species including vanadium carbide. The interaction between nickel and vanadium lowered the initial gasification rate but also slowed the deactivation of the nickel.

abstract: We study the Merton investment problem in insurance where the risk process is based on the general compound Hawkes process. That means the arrival of claims modeled with a Hawkes process and the modeled claim sizes follow a finite number of fixed jump sizes governed by a Markov chain evolution. The Merton investment problem in insurance is an optimal control problem and we use the dynamic programming method to derive the stochastic Hamilton-Jacobi-Bellman (SHJB) equation satisfied by the value function. The stochastic HJB equation yields a means to obtain the optimal control and thus the optimally controlled stochastic differential equation.  Finally, using the claim size from the empirical data set, we simulate the optimal investment portfolio and risk process.

abstract: The main obJective of this thesis is to develop a typology of the Kintampo cultural assemblage based upon materials obtained from the Kintampo culture levels, and Kintampo-related surface finds of Daboya, Northern Ghana. The Kintampo culture is believed to represent the earliest farming village communities that inhabited the savanna woodland belt of Ghana. Ever since the culture was identified and defined, there has not been a detailed analysis of the associated artifacts and this has limited the reconstruction of the processes of change to and within the culture. The classification of Daboya Kintampo artifacts can serve as a framework for detailed comparative studies of the culture with other early agricultural village communities in West Africa. The thesis is divided into six chapters. The first is a revival of evidence for the earliest farming villages in West Africa including information on environmental change associated with them. Chapter 2 consists of a brief geography of Daboya, a description of my research at Daboya and summaries materials at of data on other the site. The pits that yielded Kintampo classification of Daboya Kintampo and Kintampo-related pottery is presented in chapter three while the rest of the archaeological finds are analysed in the fourth. Chapter 5 has two sections, the first being a synthesis of the information obtained on the Kintampo occupation. The second section is a comparison of the Daboya Kintampo information with data from other excavated Kintampo culture sites. In the final chapter, the relationships of the Kintampo culture in time and space are evaluated based upon the data from Daboya, other Kintampo culture sites, and West Africa at large.

subject: Chemical Torrefaction, Gasification

abstract:
Torrefaction is a thermo-chemical process, carried out at a relatively low temperature ranging from 200-300°C. This research focuses on torrefaction of flax straw at laboratory scale. A Thermo Gravimetric Analyzer (TGA) was used to study the effect of temperature, particle size and residence time on the torrefaction of flax straw. Proximate analysis of the char showed a significant increase in fixed carbon and ash content, and a noticeable decrease in the moisture and volatile content with an increase in the temperature. Ultimate analysis was performed for the product char and from these results heating value of the torrefied char was calculated. The kinetic analysis showed an activation energy of 76.64 kJ mol-1, for the particle size of 925 µm. The experimental results of the torrefaction of flax straw indicated that the temperature had greater effect on torrefaction process than the residence time and the particle size’s chosen for this study.
CO2 gasification of flax straw char produced by two different processes namely torrefaction and pyrolysis was investigated using a TGA. The objective of this research was to investigate the diffusion and surface reactions that occur during the CO2 gasification of the torrefied and pyrolysed char particles. Gasification experiments were carried out at four different temperature range from 750 to 900ᵒC and at different particle sizes (<90 µm to 925 µm). The effects of temperatures, particle sizes, and the char types on the rate of CO2 gasification process were determined. The reactivity of the char particles at 50% conversion showed an increase in the reactivity values with a corresponding increase in the temperature and decreased with an increase in the particle sizes for both the char types. The diffusional parameters such as effective diffusivity, effectiveness factor, and Diffusion limitation index (DLI) were calculated from the experimental data for both the char types.

abstract:
Strata of the upper Bowser Lake Group in the northern Bowser Basin includes Oxfordian to Early Cretaceous, pre-Albian elastics which were interpreted to have been deposited in a shallow shelf to upper delta plain and alluvial fan setting on the basis of facies relationships, trace fossils, marine, brackish and fresh water faunas, plant macrofossil assemblages, coal chemistry and siderite and pyrite distribution. The strata studied include, in ascending order, the Jackson unit, and the Currier, McEvoy and Devils Claw formations.

The lowermost Jackson unit is a record of storm-dominated shoreface and foreshore deposition in a high energy, largely gravel-dominated shoreline during Oxfordian to Tithonian time. Bioturbation is minimal. Environmentally diagnostic sedimentary structures in the 1-20 m thick coarsening-upwards sequences include hummocky and low angle planar cross-stratification. The occurrence of dispersed pebbles, bivalve coquinas, shore-parallel large fossil logs and plant detritus increases upwards.

The overlying, anthracite-bearing, Currier Formation is interpreted to have been deposited in an interdistributrury bay setting. This interpretation is based on a brackish water trace fossil assemblage of mixed Skolithos-Cruziana ichnofacies affinity, the macrofaunal content, coal chemistry and facies associations. Common facies in this environment include: 1) Macaronichnus-bearing shallow subtidal to intertidal beach sandstones; 2) trough cross-bedded fluvial and/or tidal channels; 3) crevasse splay deposits; 4) floodplain and lacustrine sediments with the fresh water bivalve Ferganoconcha and the ichnogenus cf. Cochlichnus; 5) coal; and 6) bioturbated, fine grained bay-fill sequences. Facies associations attest to the interplay between two dominant processes: 1) interdistributary bay filling by overbank flooding and crevasse splay processes; and 2) transgression by marine waters of fresh and brackish water peat swamps, probably caused by local subsidence.

Fluvial channels, very thin coals, floodplain and crevasse splay facies of theoverlying non-marine McEvoy Formation pass upwards into conglomerate-dominated proximal braidplain and alluvial fan streamflow and debris flow facies of the Devils Claw Formation.

 The Kimmeridgian to Hauterivian unconformity, traditionally interpreted for the southern Bowser Basin, and recently extended into this area on the basis of palynology, is challenged on the basis of the sedimentological model as well as the faunal and floral assemblages. The lowermost Jackson unit contains a suite of biostratigraphically significant, Late Jurassic (mid Oxfordian to Tithonian) Buchia spp. and Vaugonia doroschini, recorded for the first time in the Groundhog coalfield. The overlying Currier, McEvoy and Devils Claw formations contain the Early Cretaceous (Neocomian) bivalve Herzogina, in addition to pre-Aptian plant macrofossil assemblages dominated by typically Jurassic and Early Cretaceous (Aptian and older) cycadophytes, ginkgophytes and fems.

abstract:
The use of trade and economic sanctions as diplomatic tools has changed over time in order to adapt to changing realities: an increase in global political and economic interdependence and relative aversion to use of force: sanctions are becoming more common,1 increasingly targeted, and applied towards individuals.2 More recently, the increased importance of economic policy,3 commercial diplomacy and trade promotion,4 coupled with and in many ways the result of a truly interconnected world renders it useful to reassess some of the calculations involved in utilizing economic sanctions. Global commerce, company structures, and financial flows are increasingly complex and ambiguous, increasing the confusion already inherent to sanctions implementation. Technological advances (such as e-commerce), the growing importance of the internet as a factor for enhancing business and export success, and government's relatively slow adoption of new technologies, have presented new challenges which have not yet adequately been factored in to the sender's5 cost calculation in the use of sanctions.
The domestic burden on the sanctions sender has not adequately considered the opportunity cost of tasking trade bureaus with sanctions-related work. Trade bureaus and diplomats play significant roles in a country's export successes, which is directly linked to domestic job creation as well as foreign policy objectives. The opportunity cost of sanctions communication and application on trade bureaucrats should be measured, and in certain cases, when appropriate and recommended by cost-benefit analysis, the burden should be shifted to other departments which are more aptly suited to efficiently handle it, or preferably, to automated and integrated websites. The calculation of this detrimental effect should be a staple of pre-sanctions analysis and using the right tools it can be mitigated or avoided altogether, therefore reducing the domestic burden of sanctions on the sender.

subject: History History Missionary Indigenous Pilgrimage

abstract: The Lac Ste-Anne Pilgrimage is an Indigenous-Catholic gathering that takes place along the lake at Lac Ste-Anne, Alberta, seventy-five kilometres west of Edmonton, and continues to attract approximately 50, 000 pilgrims yearly, most of them of First Nations or Métis heritage. It was initiated on June 6, 1889, by Jean-Marie Lestanc, a Catholic father with the Oblates of Mary Immaculate, a congregation which originated in Marseilles, France. This thesis discusses the long history of both Catholic pilgrimage and aboriginal rendezvous traditions in France and Canada respectively, and addresses the complexity of conversion among North-Western Canadian indigenous peoples in the nineteenth century. It suggests that the event was borne of an implicit negotiation and compromise between the largely francophone Oblate fathers and the local First Nations and Métis peoples over the significance of Lac Ste-Anne, and the “nomadic” ritual journey needed to arrive there.

abstract: This study explored the meditative practice and non-meditative process of mindfulness and its application to educational leadership.  The definition of mindfulness that guided this research was – being attentive and aware in the present moment.  Mindfulness was viewed as being more than meditation; it was seen as clear comprehension of a situation and being prepared and willing to address whatever happened.  It was a way of understanding one’s self and one’s self in relation to others and the world.  The purpose of this research was to construct a conceptualization of mindful educational leadership. This Scholarly Personal Narrative (Nash, 2004; Nash & Bradley, 2011; Nash & Viray, 2013) study provided a conceptualization of what it means to be a mindful educational leader.  The conceptualization came from the application of a review: of mindfulness; of leadership as expressed in a way closest to mindfulness, and through the application of Scholarly Personal Narrative to the researcher’s experiences as an educational leader, and as a participant in major life-changing events.  Data collection included: epistolary letters, journal reflections, as well as narrative and poetic life texts.  A parallax vantage analysis was utilized to uncover and identify universalizable themes within the narrative.  These themes offered an understanding of the duality of mindfulness (awareness of self and others) that was linked to the duality of leadership that, at its base, is about the leader and the follower, and thus it is both self and relational.  The resulting construct of mindful educational leadership would fill a gap in the academic literature on leadership and would offer to educational leaders, a reflective and purposeful way of being in the world.

abstract: Immunotherapy is an emerging field of cancer treatment that is transforming the management of numerous human cancers. However, there remains a substantial proportion of cancer subtypes that are unresponsive to many modern immunotherapy strategies. Soft tissue sarcomas (STS) are aggressive, connective-tissue derived solid cancers and are notoriously resistant to systemic therapies including immunotherapy. Immunologically, sarcomas are frequently characterized by a paucity of lymphocytic infiltrates, an immune suppressive microenvironment, and resistance to immunotherapies such as immune checkpoint inhibition and oncolytic viruses. Activation of the STING (stimulator of interferon genes) pathway can induce potent innate and adaptive anti-tumour immune responses within immunogenic solid tumours. However, this approach has never been tried in immune-inert sarcomas. Herein, STING activation in STS was analyzed to determine if STING activation could induce therapeutic anti-tumour effects and promote anti-tumour immunity. The long-term therapeutic responses of STING activation via 5,6-dimethylxanthenone-4-acetic acid (DMXAA) injection were assessed using a syngeneic murine model of undifferentiated pleomorphic sarcoma (UPS). Intratumoural DMXAA resulted in a durable cure in 50-60% of UPS-bearing mice. Flow cytometry was used to quantify immune infiltration after STING activation treatment and a higher proportion of CD8+/CD3+ cells was observed seven days post DMXAA treatment compared to the vehicle control treatment. Surviving mice all rejected UPS re-challenge in both the extremity and lung, and the therapeutic effects of DMXAA were mitigated by lymphocyte deficiency suggesting adaptive immunologic pathways are integral to the therapeutic response. This data suggests modulation of the STING pathway can elicit local and systemic anti-tumour immune responses in UPS and deserves further consideration as a novel local and systemic treatment for sarcomas.

abstract:
In social computing, multiple users may share privacy stakes in a content. Contents contributed by a user may be annotated by other users (e.g., “like” or “comment”). Also users may get associated to a content that is contributed by other users (e.g., get tagged in a photo). In other scenarios, multiple users may co-contribute a piece of information (e.g., friendship articulation). These users, called co-owners in this thesis, share privacy stakes in these contents and they may want to control access to the contents. In this novel situation of multiple ownership a shared resource is administrated simultaneously by co-owners who may have conflicting privacy preferences and/or sharing needs. The study of access control schemes for multiple ownership in social computing has captured the imagination of researchers, and general-purpose schemes for reconciling the differences of privacy stakeholders have been proposed.
   One challenge of existing general-purpose multiple-ownership schemes is that they can be very complex. In the first part of this thesis, we consider the possibility of simplification in special cases. We identify two simple design patterns for handling a significant family of multiple-ownership scenarios. We discuss efficient implementation techniques that solely rely on standard SQL technology. We also identify scenarios in which general-purpose multiple-ownership schemes are necessary.
   Most of the general-purpose schemes in the literature are in the form of unsupervised conflict resolution mechanisms. In the second part of this thesis, driven by the need for human consent in organizational settings, we explore interactive policy negotiation, a different approach but complementary to that of prior work. Specifically, we propose an extension
of Relationship-Based Access Control (ReBAC) to support multiple ownership, in which a policy negotiation protocol is in place for co-owners to come up with and give consent to an access control policy in a structured manner. During negotiation, the quality of the draft policy is assessed by a set of novel and formally defined availability criteria: policy satisfiability, feasibility and resiliency, which all belong to the second level of the polynomial hierarchy. We then propose efficient tool support for deciding these availability criteria.

prolactin, breast cancer, DNA damage

abstract: High serum levels of the peptide hormone prolactin are associated with increased breast cancer risk and poor prognosis. Prolactin is also involved in breast cancer resistance to different chemotherapeutics. The overall goal of this project is to investigate potential pathways involved in prolactin induced resistance to DNA damaging agents with the hypothesis that the cross-talk between the prolactin pathway and the DNA damage response is important in the mechanism. We previously identified that one isoform of heat shock protein-90 (HSP90), Hsp90alpha, is a prolactin-Janus kinase-2 (Jak2)-signal transducer and activator of transcription-5 (Stat5) regulated gene in breast cancer cells. We have now observed that prolactin increased the viability of breast cancer cells to DNA damaging chemotherapeutics, and Hsp90 inhibitors, 17AAG and BIIB021, abrogated the effect of prolactin, indicating the mechanism of enhanced viability involves the master cancer chaperone Hsp90. The stability of Jak2 and both the total ataxia-telangiectasia mutated protein (ATM) and phospho-ATM appear to be dependent on functional Hsp90. Inhibition of Jak2 and ATM, with highly selective inhibitors (G6 and KU55933, respectively), abrogated prolactin enhanced viability, suggesting their role in prolactin induced cell viability. Drug combination experiments with Hsp90 inhibitor BIIB021 and doxorubicin, and ATM inhibitor KU55933 and doxorubicin, showed drug synergism between doxorubicin and both KU55933 and BIIB021 in MCF7 breast cancer cells. Interestingly, in orthotopic xenograft studies, autocrine prolactin from human breast cancer cells increased the tumor latency of doxorubicin induced DNA damaged cells in SCID mice compared to untreated or prolactin or doxorubicin alone. We hypothesize that this is in part due to the cross-talk of the prolactin and DNA damage response pathways that may be affecting the tumor microenvironment.

abstract: The central aims of the present study were to determine if mindfulness and distraction inductions would decrease rumination following a stressor and to investigate whether changes in post stressor rumination would influence cardiovascular recovery. Additional goals were to assess the influence of a brief mindfulness meditation intervention on rumination, mindfulness, depressed mood and symptoms of stress. Cardiovascular and psychological data was collected from 101 undergraduate students during two identical laboratory-testing sessions 5 weeks apart. Each testing session included a 5-minute baseline period, 5-minute stress task and a 15-minute recovery period. Participants were randomized to one of three conditions: mindfulness, distraction or control. During the recovery period, participants in the distraction condition received a distraction induction, those in the control condition received no induction and those in the mindfulness condition received a mindfulness induction. Participants in the mindfulness condition also received a 4-week mindfulness meditation intervention during the period between laboratory testing sessions while participants in the distraction and control conditions received no intervention. Results indicated that, at testing session two, participants in the mindfulness condition showed the greatest decreases in post stressor state rumination compared to the other conditions. The conditions did not differ on cardiovascular reactivity or recovery at either testing session. Mindfulness participants reported increases in trait mindfulness and decreases in depressed mood, following the brief mindfulness meditation intervention, compared to participants who did not receive the intervention. The brief mindfulness intervention was not associated with changes in trait rumination or symptoms of stress. The preliminary findings of the present study suggest the efficacy of a brief mindfulness meditation intervention for decreasing depressed mood, decreasing state rumination, in response to mental stress, and increasing mindfulness compared to a no-intervention control.

abstract: Biological membranes are complex cellular structures formed by a large number of different lipid types, that also contain a variety of bound proteins, carbohydrates, and other molecules. The detailed orchestration of all these elements has been a major focus of scientific research during the last 5 decades. Computer-based methods, such as molecular dynamics (MD) simulations, have proven to be a valuable approach in addressing many of the details of lipid organization and membrane protein activity. I used MD simulations at both atomistic and coarse-grained level of detail to study the number of way lipids and proteins interact and their possible functional ramifications. In part of my work, I studied the interaction of G Protein-Coupled Receptors (GPCRs) with lipids at a family-wide level. Plenty of other computational studies had shown specific lipid-protein interactions for a handful of GPCRs but with quite different outcomes on their number, location, and lipid identity. In my work, I simulated 28 different GPCR structures and showed that they are distinguished by a unique interaction profile with membrane lipids. I provided a comprehensive analysis of simulation results with available crystallographic data. I also studied the lipid-protein interaction profile of AMPA receptors and cyclooxygenases (mainly COX-1), showing that they both form specific interactions with lipids, but do so in a quite different fashion. AMPA receptors interact specifically with diacylglycerol lipids, whereas COX-1 enzymes do so indiscriminately with glycerophospholipids, cholesterol, and fatty acids, but at different levels of interaction strength. Using atomistic simulations, we show the binding pathway of arachidonic acid to COX-1 and identify a series of arginine residues that guide it toward the hydrophobic cavity of the enzyme. As part of my work, I also developed a webserver that automates the analysis and visualization of lipid-protein interactions from MD simulations allowing for the creation of automated pipelines to study lipid-protein interactions in the future. Lastly, I provide a short review of some of the main challenges facing the field along with possible solutions going forward. My work expands our understanding of lipid-protein interactions.

abstract: Wireless Sensor Network (WSN) is a self-organizing, infrastructure-less network of miniature sensors. In this study, we introduce the concept of coverage confidence level and present a detailed analysis on Sensing Spatial Coverage (SSC) of WSN. This analysis aims to determine the required resources for WSN design and implementation. A detailed mathematical sensing model is proposed for photodiodes for a fire detection application. This work also considers the sensors directionality. Afterwards, an improved network lifetime definition is proposed based on the SSC analysis which is more consistent with real-world applications. Finally, a novel routing protocol known as the Lifetime Improved Collection Tree Protocol (LICTP) is proposed, and implemented. LICTP’s performance is evaluated and analyzed via simulations and experiments on a lab set-up that consisted of 25 motes. Results show that LICTP improves the lifetime efficiency by a factor of 2.3 - 2.8 in comparison with commonly used Collection Tree Protocol (CTP).

abstract:
The cestode Echinococcus multilocularis is a trophically-transmitted parasite that is typically maintained in a sylvatic cycle involving wild canid definitive hosts and small mammal intermediate hosts. As etiological agent of Alveolar Echinococcosis in humans, the cestode is currently the third most impacting food-borne parasite globally. Understanding E. multilocularis transmission ecology, combined with reliable diagnostic and surveillance of parasite infection in wild hosts, is crucial for disease prevention and risk management.
In Calgary, Canada, E. multilocularis was found to infect 29.5% (n = 61) of road-killed urban coyotes (Canis latrans) collected in 2009-2010. For the detection of E. multilocularis eggs in coyote feces, sugar fecal flotation showed lower sensitivity than the ZnCl2 centrifugation and sedimentation protocol (0.46 vs. 0.75). The latter technique is therefore recommended for screening of canid hosts.
This study provided the first evidence of an urban sylvatic cycle of E. multilocularis in North America. Parasite prevalence in coyote feces was shown to vary temporally (10.5-43.5%) and spatially (5.3-61.5%) across five city parks, and infection of small mammal intermediate hosts was documented in three competent species (prevalence ranging between 0.7 and 1.4%). Genotyping coyote feces (n = 142) at 4-6 microsatellite loci allowed to correct for repeated sampling of individuals, and to estimate an overall parasite prevalence of 25.0%. Importantly, individual patterns of infection (i.e., parasite egg intensity in feces) allowed to observe temporal variations in parasite transmission that were not detected when examining fecal samples of unknown identity. By looking at the recovery of parasite eggs in genotyped feces over time, a re-infection rate of 57% (n =7) was estimated for coyotes in an area of parasite hyper-endemicity.
Winter was a crucial period for E. multilocularis transmission, as the encounter rate of coyote with the parasite (number of infected hosts ingested) was higher than any other season (95% CI: 1.0-22.4). Voles (Microtus pennsylvanicus and Myodes gapperi) were consumed by coyotes proportionally more than their availability, and likely played a key role for the maintenance of the urban sylvatic life-cycle of E. multilocularis in this urban landscape.

abstract:
This thesis proposes practical improvements to arithmetic and exponentiation in the ideal class group of imaginary quadratic number fields for the Intel x64 architecture. This is useful in tabulating the class number and class group structure, but also as an application to a novel integer factoring algorithm called “SuperSPAR”. SuperSPAR builds upon SPAR using an idea from Sutherland, namely a bounded primorial steps search, as well as by using optimized double-based representations of exponents, and general improvements to arithmetic in the ideal class group.

Since the target architecture has 64 bit machine words, we specialize two implementations of ideal class arithmetic: one using 64 bit arithmetic, and the other using 128 bit arithmetic. In each case, our results show an improvement in the average performance of ideal class arithmetic over reference implementations. Since much of the effort of ideal class arithmetic is in computing the extended greatest common divisor, this thesis studies the average performance of several implementations of this and shows an improvement for some over reference implementations. Dimitrov and Cooklev propose the double base number system, and Imbert, Jacobson, and Schmidt propose a method of ideal class cubing. Using these ideas, we explore several techniques for exponentiation using 2,3 number systems and demonstrate an improvement in the average performance of exponentiation in the ideal class group over that of binary exponentiation. Lastly, each of these improvements are applied to our implementation of the SuperSPAR factoring algorithm, and our results show an improvement in the average time to factor integers 49 bits to 62 bits in size.

abstract: The intention of this project was an architectural investigation that used the cultural paradigm of man's obsession with physical beauty and perfection as a vehicle for development. For the discussion of beauty on an architectural level, a laser eye surgery clinic was chosen as the basis for design. It was seen as an architectural intervention that examined both traditional and present day understandings of physical beauty and their manifestations. It also examined the ideas of medicine, it's changing role in society, self image, body image, building and landscape. Beauty as an idea has transcended the boundaries of time and space, being a link binding all human-kind together. The only real changes that have occurred over time are; what is considered beautiful and, what sorts of interventions occur to create that beauty. Through technological advances', mankind has been able to affect beauty in more invasive ways. Traditionally, topical appliques were used to enhance physical appearance. Presently, more invasive methods of surgery are used to affect the individual. As people are willing to go to greater lengths to affect their physical appearance it is obvious that there is a strong relationship between physical beauty and mental well being. It is important that the issue of beauty be addressed as it is seen as an important cultural issue. It is this importance that will cause the issue to pervade other areas of society and culture,. Because this issue will become intertwined within other areas of culture it is important that this topic get appropriate study and thought.

abstract: This study shows how Antioquia elites re-imagined, through commemorations, their collective past and invented their region, as a symbolic appropriation of the space – the highlands – that they inhabited. The identity that emerged from that process was the basis on which Antioqueño elites negotiated hegemony with those of the national capital. Here I show for the first time how provincial institutions, town councils and local elites promoted cultural events that proclaimed the affirmation of a “historical region” and at the same time insisted upon their Colombianidad (Colombianness). Antioqueño elites saw regional history as the mean to emphasize their contribution to a common national identity dating back to the wars of independence. I argue in this dissertation, regional and local elites in Antioquia opposed the history that the Liberals in the capital wanted to impose, which presupposed the existence of a nation before the war of independence. In addition to having challenged the power of the capital through war, regional elites did not find in the nationalization of the anniversary of Bogota’s independence the idea of a stable community advancing towards the liberal utopia.

abstract: Slips, trips and falls are one of the leading causes of injury and result in billions of dollars in medical and insurance costs annually. Current determination of slip potential does not always accurately predict whether an individual will slip or not. To better predict slip incidents, it may be possible to evaluate only one component, horizontal force, of the current friction calculation. The purpose of this dissertation was to determine if horizontal force generation would serve as a more accurate predictor of slip probability for movements associated with a high-risk of slipping; a 90° change in direction. It was discovered that if at least 50N of horizontal force was generated by 10.08ms following heel-strike, the corresponding slip distance was less than 100mm. By using the horizontal force generation associated with early heel-strike, the probability of correctly classifying slip and non-slip situations was greater compared to the currently utilized friction method.

abstract: Background: High-risk adenomas (HRAs) are precursors to colorectal cancer (CRC), and removing them during colonoscopy can halt progression to CRC. The aim of this study was to develop a risk prediction model for HRAs detected at screening colonoscopy based on readily available patient information. Subsequently, we aimed to understand if biomarkers of glucose  metabolism were associated with HRAs, with hopes incorporating them into a baseline risk prediction model to enhance its clinical utility. Methods: The cohort consisted of 3,035 individuals aged 50 to 74 years with no prior history of cancer who underwent a primary screening colonoscopy at a centralized colon cancer screening centre between 2008 and 2016. A multivariable logistic regression model was created using CRC risk factors identified from prior research. Model covariates were collected from a baseline questionnaire and included patient demographics (age and sex), lifestyle parameters (body mass index, alcohol, smoking, and vitamin D supplement use) and medical history (family history of CRC and diabetes). Model calibration was assessed using the c-statistic. Glucose, insulin, glycated hemoglobin A1c, and c-peptide were all measured were assessed using a case control study design from from a subset of the CCSC biorepository.conditional logistic regression was used to understand their associations with HRAs. Results: Mean participant age was 58.8 years, and 54.7% were male. A total of 249 participants with HRAs were identified (8.2%). An optimism adjusted c-statistic of 0.67 was calculated, and a specificity and negative predictive value of  97.0% and 92.4% for the detection of HRAs respectively, were achieved using 20% predicted probability as a high-risk threshold. However, a sensitivity of only 10.8% was achieved. Our model has moderate predictive ability, with strengths in being able to rule those with an absence of HRAs on screening colonoscopy. Finally, after adjustment, no meaningful associations were found between these four biomarkers of glucose metabolism and HRAs. Conclusion: Although these glucose metabolism biomarkers were not found to be associated with HRAs, the production of a simple risk prediction model can still provide benefit to the current screening programs in Alberta. Maximizing screening efficiency through improved risk prediction can enhance resource allocation. Ultimately, this model has the potential to improve patient care by reducing unnecessary colonoscopies, limiting this invasive procedure to those most likely to have significant findings.
