description: We study the properties of compacton-anticompacton collision processes. We compare and con- trast results for the case of compacton-anticompacton solutions of the K(l, p) Rosenau-Hyman (RH) equation for l = p = 2, with compacton-anticompacton solutions of the L(l,p) Cooper-Shepard- Sodano (CSS) equation for p = 1 and l = 3. This study is performed using a Padé discretization of the RH and CSS equations. We find a significant difference in the behavior of compacton- anticompacton scattering. For the CSS equation, the scattering can be interpreted as "annihila- tion" as the wake left behind dissolves over time. In the RH equation, the numerical evidence is that multiple shocks form after the collision which eventually lead to "blowup" of the resulting waveform.

title: Mythology, Ideology and the Contemporary American Short Story Cycle
Creators: name: Edwards, Robert
Publisher: name: University of Kent
Year: 2016

description: The present study proposes that there is an intrinsic relationship between the contemporary American short story cycle and the myth and ideology of the United States. I argue that the contemporary form of the story cycle has become the genre of choice for certain authors whose work explicitly challenges the dominant ideological discourses of Euroamerica and its underpinning mythologies. The five authors and the texts I discuss are Tim O’Brien and The Things They Carried, Julia Alvarez and How The Garcia Girls Lost Their Accents, Gerald Vizenor and Landfill Meditation, Sherman Alexie and Ten Little Indians, and Thomas King and Green Grass, Running Water. In the thesis I address the interrelationship between ideology and mythology and this is the foundation for my examination of the way that these five disparate writers each uses the story cycle in his or her own distinctive way to challenge a dominant ideology and the mythology that underpins it.

description: We fabricated a double negative acoustic metamaterial which consisted of Helmholtz resonators and membranes. Experimental data on the transmission and dispersion relation are presented. The system exhibits three frequencies where the acoustic state makes sharp transitions from density negative (ρ -NG) to double negative (DNG), modulus negative (B-NG), and double positive (DPS) in sequence with the frequency. We observed a wide range of negative refractive index from -0.06 to -3.7 relative to air, which will allow for new acoustic transformation techniques.

description: Objective: Acute kidney injury (AKI) is associated with higher morbidity and mortality in cardiac arrest (CA). There are limited contemporary data on the incidence and outcomes of AKI in CA. Methods: We comprehensively searched the databases of MEDLINE, EMBASE, PUBMED, and the Cochrane from inception to November 2020. Observational studies that reported the incidence of AKI in CA survivors were included. Data from each study were combined using the random effects to calculate pooled incidence and risk ratios with 95% confidence intervals (CIs). The primary outcome was short-term mortality and secondary outcomes included long-term mortality, incidence of AKI, and use of renal replacement therapy (RRT). Subgroup and meta-regression analyses were performed to explore heterogeneity. Main results: A total of 25 observational studies comprising 8,165 patients were included. The incidence of AKI in CA survivors was 40.3% (range 32.9–47.8%). In stage 3 AKI, one-fourth of patients required RRT. AKI was associated with an increased risk of both short-term (OR 2.27 [95% CI 1.74–2.96]; p p Conclusion: AKI complicates the care of 40% of CA survivors and is associated with significantly increased short- and long-term mortality.

Time-travel programming: programming language support for interacting with past executions
Creators: name: Salkeld, Robin
Publisher: name: University of British Columbia
Year: 2018

description: Because software so often behaves unexpectedly or fails only in production environments, several recent tools from both industry and academia record data about execution for the benefit of post-hoc analysis. Debugging on these data instead of a live program is much more difficult, however, because the semantic abstractions provided by the programming language are no longer available. Many post-hoc analysis tools process this data through additional reflection-based code or domain-specific query languages, but do not recover the expressive power of the original programming language. This thesis proposes the concept of time-travel programming, which we define as simulating the execution of additional code in the same programming language as if it were present in the past environment of recorded data. Furthermore, we show that the aspect-oriented programming (AOP) paradigm provides a natural mechanism for specifying this additional execution, and allows us to reuse established semantics and implementations. We provide evidence of this technique’s flexibility, feasibility and effectiveness through two implementations: one an interpreter for an extremely simple AOP language in the style of a core calculus, and one for the AspectJ programming language. We evaluate flexibility via applying the implementations to multiple execution recording formats, feasibility by showing the AspectJ implementation is performant enough for post-hoc analysis, and effectiveness by demonstrating that evaluating new and existing aspects retroactively can be used to address common post-hoc analysis tasks.

description: We investigate whether it is possible to explain the wide range of observed gradients in early type galaxies in the framework of monolithic models. To do so, we extend the set of hydrodynamical simulations by Pipino et al. (2008a) by including low-mass ellipticals and spiral (true) bulges. These models satisfy the mass-metallicity and the mass-[alpha/Fe] relations. The typical metallicity gradients predicted by our models have a slope of -0.3 dex per decade variation in radius, consistent with the mean values of several observational samples. However, we also find a few quite massive galaxies in which this slope is -0.5 dex per decade, in agreement with some recent data. In particular, we find a mild dependence from the mass tracers when we transform the stellar abundance gradients into radial variations of the Mg_2 line-strength index, but not in the Mg_b. We conclude that, rather than a mass- slope relation, is more appropriate to speak of an increase in the scatter of the gradient slope with the galactic mass. We can explain such a behaviour with different efficiencies of star formation in the framework of the revised monolithic formation scenario, hence the scatter in the observed gradients should not be used as an evidence of the need of mergers. Indeed, model galaxies that exhibit the steepest gradient slopes are preferentially those with the highest star formation efficiency at that given mass.

description: Analyzing how provenance signatures of tectonically complex ancient sedimentary basins vary between the outcrop and the subsurface is crucial to understanding basin filling history. The 500+ km-long outcrop belt of the Magallanes-Austral Basin in southern Patagonia and its subsurface to the east allows us to constrain relationships between longitudinal and transverse sediment sources feeding the basin. New detrital zircon U-Pb ages (n=2558) from nine subsurface core samples from the Springhill, Piedra Clavada, and La Anita Formations along a 140 km east-west seismic reflection transect (50°S latitude; 71.5-69.5°W longitude) reveal provenance and filling history of the basin’s eastern subsurface extent. Detrital zircon ages (n=1068) were also collected from four outcrop Springhill Formation samples 140 km northwest from the transect near Lago San Martin. Maximum depositional ages (MDAs) from the Springhill Formation cores range from 154.9–146.8 Ma, which are older than correlative outcrop ages of 144.6–126.7 Ma. MDAs from the Piedra Clavada and La Anita Formations range from 93.4–91.4 Ma and 78.9–78.3 Ma, respectively, and overlap in age or are slightly younger than outcrop ages. The unimodal Late Jurassic age distribution from the Springhill Formation suggests that it almost exclusively was sourced by recycling of its underlying El Quemado Complex and highlights the underfilled nature of the Rocas Verdes Basin. By the Early Cretaceous, detritus supplied to the basin was derived from the arc, fold and thrust belt, and distal synrift volcanic sources. The occurrence of Early–Middle Jurassic ages in the Piedra Clavada Formation samples suggest either the basin was sourcing from the North Patagonia Massif to the north-northeast and from the Deseado Massif to the northeast or recycling exhumed volcaniclastic sequences in the northern margin of the basin. By the Late Cretaceous, the basin fill was more locally sourced, as suggested by the muted signal of Early–Middle Jurassic ages in La Anita Formation samples and a second mode of Late Jurassic–Early Cretaceous ages locally derived from recycling exhumed El Quemado Complex from the fold and thrust belt. We suggest that the longitudinal and local transverse drainages that sourced the Magallanes-Austral Basin outcrop belt also propagated eastward across the basin (what is now subsurface strata). Distal sourcing from the North Patagonian Massif is determined by subsidence and bypass in the Golfo San Jorge Basin and existence of Albian–Turonian fluvial transport systems capable of transporting Jurassic sediment to the Magallanes-Austral Basin.

description: Introduction: Although in-person hospitalist presence, increasingly staffed by dedicated nocturnists, has become the norm overnight in the hospital, the scope of nocturnist practice and typical workload has not been defined. This study examines the clinical responsibilities and patient safety perceptions of hospitalists who work night shifts in the United States. Methods: In the fall of 2019, a cross-sectional, web-based survey was administered to physician and nurse practitioner/physician assistant (NP/PA) hospitalists who work night shifts. The questionnaire assessed night staffing structure, typical responsibilities, patient volume, perceptions of safety overnight, as well as demographic information. The survey was posted on the Society of Hospital Medicine (SHM) Hospital Medicine Exchange (HMX) Online Discussion Forum. Additionally, the survey was distributed by ‘snowball method’ by respondents to other night hospitalists. Responses were collected anonymously. Results: Of the 167 respondents, 157 reported working night shifts. There was at least one respondent from 32 different states. In addition to performing admissions to medicine services and covering inpatients, night hospitalists cover ICU patients, participate in RRT/Code teams and procedure teams, perform consults, participate in medical education, and take outpatient calls. Across institutions, there was a large distribution in numbers of patients covered in a night shift; however, patient volume fell into typical ranges: 5–10 admissions for physicians, 0–6 admissions for NP/PAs, and 25–75 patient cross-coverage census. When physicians perform more than five admissions per night, hospitalists were less likely to agree that they could provide safe care (88% vs. 63%, p = 0.0006). Conclusions: This is the first national study to examine the clinical responsibilities of hospitalists working overnight. Overnight responsibilities are heterogeneous across institutions. As hospitals are increasingly employing nocturnists, more research is needed to guide night staffing and optimize patient safety.

Deep learning for feature discovery in brain MRIs for patient-level classification with applications to multiple sclerosis
Creators: name: Yoo, Youngjin
Publisher: name: University of British Columbia
Year: 2018

description: Network architectures and training strategies are crucial considerations in applying deep learning to neuroimaging data, but attaining optimal performance still remains challenging, because the images involved are high-dimensional and the pathological patterns to be modeled are often subtle. Additional challenges include limited annotations, heterogeneous modalities, and sparsity of certain image types. In this thesis, we have developed detailed methodologies to overcome these challenges for automatic feature extraction from multimodal neuroimaging data to perform image-level classification and segmentation, with applications to multiple sclerosis (MS). We developed our new methods in the context of four MS applications. The first was the development of an unsupervised deep network for MS lesion segmentation that was the first to use image features that were learned completely automatically, using unlabeled data. The deep-learned features were then refined with a supervised classifier, using a much smaller set of annotated images. We assessed the impact of unsupervised learning by observing the segmentation performance when the amount of unlabeled data was varied. Secondly, we developed an unsupervised learning method for modeling joint features from quantitative and anatomical MRIs to detect early MS pathology, which was novel in the use of deep learning to integrate high-dimensional myelin and structural images. Thirdly, we developed a supervised model that extracts brain lesion features that can predict conversion to MS in patients with early isolated symptoms. To efficiently train a convolutional neural network on sparse lesion masks and to reduce the risk of overfitting, we proposed utilizing the Euclidean distance transform for increasing information density, and a combination of downsampling, unsupervised pretraining and regularization during training. The fourth method models multimodal features between brain lesion and diffusion patterns to distinguish between MS and neuromyelitis optica, a neurological disorder similar to MS, to support differential diagnosis. We present a novel hierarchical multimodal fusion architecture that can improve joint learning of heterogeneous imaging modalities. Our results show that these models can discover subtle patterns of MS pathology and provide enhanced classification and prediction performance over the imaging biomarkers previously used in clinical studies, even with relatively small sample sizes.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: The motion of micro- and nanomechanical resonators can be coupled to electromagnetic fields. This allows to explore the mutual interaction and introduces new means to manipulate and control both light and mechanical motion. Such optomechanical systems have recently been implemented in nanoelectromechanical systems involving a nanomechanical beam coupled to a superconducting microwave resonator. Here, we propose optomechanical systems that involve multiple, coupled microwave resonators. In contrast to similar systems in the optical realm, the coupling frequency governing photon exchange between microwave modes is naturally comparable to typical mechanical frequencies. For instance this enables new ways to manipulate the microwave field, such as mechanically driving coherent photon dynamics between different modes. In particular we investigate two setups where the electromagnetic field is coupled either linearly or quadratically to the displacement of a nanomechanical beam. The latter scheme allows to perform QND Fock state detection. For experimentally realistic parameters we predict the possibility to measure an individual quantum jump from the mechanical ground state to the first excited state.

description: It is common in modern prediction problems for many predictor variables to be counts of rarely occurring events. This leads to design matrices in which many columns are highly sparse. The challenge posed by such “rare features” has received little attention despite its prevalence in diverse areas, ranging from natural language processing (e.g., rare words) to biology (e.g., rare species). We show, both theoretically and empirically, that not explicitly accounting for the rareness of features can greatly reduce the effectiveness of an analysis. We next propose a framework for aggregating rare features into denser features in a flexible manner that creates better predictors of the response. Our strategy leverages side information in the form of a tree that encodes feature similarity. We apply our method to data from TripAdvisor, in which we predict the numerical rating of a hotel based on the text of the associated review. Our method achieves high accuracy by making effective use of rare words; by contrast, the lasso is unable to identify highly predictive words if they are too rare. A companion R package, called rare, implements our new estimator, using the alternating direction method of multipliers.
On the classification of scalar evolutionary integrable equations in $2+1$ dimensions

description: We consider evolutionary equations of the form $u_t=F(u, w)$ where $w=D_x^{-1}D_yu$ is the nonlocality, and the right hand side $F$ is polynomial in the derivatives of $u$ and $w$. The recent paper \cite{FMN} provides a complete list of integrable third order equations of this kind. Here we extend the classification to fifth order equations. Besides the known examples of Kadomtsev-Petviashvili (KP), Veselov-Novikov (VN) and Harry Dym (HD) equations, as well as fifth order analogues and modifications thereof, our list contains a number of equations which are apparently new. We conjecture that our examples exhaust the list of scalar polynomial integrable equations with the nonlocality $w$. The classification procedure consists of two steps. First, we classify quasilinear systems which may (potentially) occur as dispersionless limits of integrable scalar evolutionary equations. After that we reconstruct dispersive terms based on the requirement of the inheritance of hydrodynamic reductions of the dispersionless limit by the full dispersive equation.

Assessment of novel accessory enzymes to enhance biomass deconstruction
Creators: name: Vargas Figueroa, Daniela Alejandra
Publisher: name: University of British Columbia
Year: 2018

description: The production of monomeric sugars from lignocellulosic feedstocks is challenging, partly due to the high enzyme loadings that are typically required to effectively break down biomass substrates. One pretreatment approach is to try to keep most of the sugars associated with the solid fraction where cellulose and hemicellulose degrading enzymes will be needed to both open-up the lignocellulosic matrix and hydrolyse the polymeric matrix. Past work has shown that the addition of “accessory enzymes” to the “cellulase” cocktail can enhance the hydrolytic performance of enzyme mixture while reducing the protein/enzyme loading required to hydrolyse pretreated biomass substrates. The potential of novel “hemicellulose-specific” enzymes to work synergistically with traditional (Celluclast) and more recent (CTec series) cellulase mixtures was assessed on a range of pretreated and “model” cellulosic substrates. Xyloglucanases showed a higher degree of cooperation than did mixed-linkage glucanases. However, although they generally enhanced cellulose hydrolysis, this synergistic cooperation was strongly influenced by the type of enzyme activity, substrate composition and enzyme and substrate concentration. The backbone-acting xyloglucanase from Bacteroides ovatus, BoGH5, demonstrated a broader specificity compared to other accessory enzymes, resulting in a higher degree of cooperation with cellulase enzymes and enhanced cellulose hydrolysis. Supplementing Celluclast with both backbone acting and debranching enzyme α-xylosidase, resulted in an over 10% improvement in cellulose hydrolysis for substrates with a higher hemicellulose content. This also correlated with an increase in the release of xyloglucan-derived oligomers. As a result of this enhanced synergism, it was possible to reduce the overall protein/enzyme loading by 35% when a goal of 80% cellulose hydrolysis of alkali pretreated corn stover within 72 hrs was targeted. The thesis work suggested that xyloglucan plays a role in limiting enzyme access to the cellulose and therefore the xyloglucan must be disrupted in order to facilitate effective cellulose hydrolysis. It is likely that xyloglucan acts as a physical barrier, possibly coating cellulose microfibrills and/or restraining cellulose fiber swelling.

description: In this article we derive the asymptotic distribution of estimated best linear unbiased predictors (EBLUPs) of the random effects in a nested error regression model. Under very mild conditions which do not require the assumption of normality, we show that asymptotically the distribution of the EBLUPs as both the number of clusters and the cluster sizes diverge to infinity is the convolution of the true distribution of the random effects and a normal distribution. This result yields very simple asymptotic approximations to and estimators of the prediction mean squared error of EBLUPs, and then asymptotic prediction intervals for the unobserved random effects. We also derive a higher order approximation to the asymptotic mean squared error and provide a detailed theoretical and empirical comparison with the well-known analytical prediction mean squared error approximations and estimators proposed by Kackar and Harville and Prasad and Rao. We show that our simple estimator of the predictor mean squared errors of EBLUPs works very well in practice when both the number of clusters and the cluster sizes are sufficiently large. Finally, we illustrate the use of the asymptotic prediction intervals with data on radon measurements of houses in Massachusetts and Arizona.

description: Bilayer graphene is a recently isolated and intriguing class of many-body systems with massive chiral quasiparticles. We present theoretical results for the electronic compressibility of bilayer graphene that are based on a four-band continuum band structure model combined with a random phase approximation treatment of electronic correlations. We find that the compressibility is strongly suppressed by electron-electron interactions at low carrier densities. Correlations do not lead to any qualitative new features, but are crucially important for a quantitative understanding of this fundamental thermodynamic property of graphene bilayers.

description: Let X be a Riemann surface of genus at most 1, i.e. X is the Riemann sphere or a torus. We construct a variety of examples of analytic functions g:W->X, where W is an arbitrary subdomain of X, that satisfy Epstein's "Ahlfors islands condition". In particular, we show that the accumulation set of any curve tending to the boundary of W can be realized as the omega-limit set of a Baker domain of such a function. As a corollary of our construction, we show that there are entire functions with Baker domains in which the iterates converge to infinity arbitrarily slowly. We also construct Ahlfors islands maps with wandering domains and logarithmic singularities, as well as examples where X is a compact hyperbolic surface.

title: Haem Biosynthesis, Utilisation, and Acquisition in Ciliates and other Protists
Creators: name: McGreig, Jake
Publisher: name: University of Kent

description: Haem is an important prosthetic group required for a variety of essential biological processes, such as respiration, as a cofactor of cytochromes, and transport of oxygen as a component of globin proteins. The ability to synthesise or obtain haem from the environment is crucial for survival of most organisms, and protists possess diverse mechanisms to achieve this. Through computational analyses of genomes and transcriptomes from a wide range of protists, novel insights into haem requirements were gained. This work revealed new information on haem biosynthetic pathways of the ciliate species of the spirotrich class, demonstrating several of these organisms encode the near complete biosynthetic pathways to synthesise haem de novo. Additionally, presence of the C5 pathway for production of ALA was predicted in five ciliate species, suggesting a new route for production of this haem precursor as previously only the C4 pathway had been identified in ciliates. Where ciliates lack the requisite enzymes to make haem, the presence of haem acquisition systems in these species was analysed. This work provides new explanations for how certain protists obtain and utilise an important cofactor, which has broader implications for niche adaptation and evolution of these poorly-understood organisms.

description: Reaction-diffusion systems where transition rates exhibit quenched disorder are common in physical and chemical systems. We study pair reactions on a periodic two-dimensional lattice, including continuous deposition and spontaneous desorption of particles. Hopping and desorption are taken to be thermally activated processes. The activation energies are drawn from a binary distribution of well depths, corresponding to `shallow' and `deep' sites. This is the simplest non-trivial distribution, which we use to examine and explain fundamental features of the system. We simulate the system using kinetic Monte Carlo methods and provide a thorough understanding of our findings. We show that the combination of shallow and deep sites broadens the temperature window in which the reaction is efficient, compared to either homogeneous system. We also examine the role of spatial correlations, including systems where one type of site is arranged in a cluster or a sublattice. Finally, we show that a simple rate equation model reproduces simulation results with very good accuracy.

description: We study the traffic dynamics in complex networks where each link is assigned a limited and identical bandwidth. Although the first-in-first-out (FIFO) queuing rule is widely applied in the routing protocol of information packets, here we argue that if we drop this rule, the overall throughput of the network can be remarkably enhanced. We proposed some efficient routing strategies that do not strictly obey the FIFO rule. Comparing with the routine shortest path strategy, the throughput for both Barabási-Albert (BA) networks and the real Internet, the throughput can be improved more than five times. We calculate the theoretical limitation of the throughput. In BA networks, our proposed strategy can achieve 88% of the theoretical optimum, yet for the real Internet, it is about 12%, implying that we have a huge space to further improve the routing strategy for the real Internet. Finally we discuss possibly promising ways to design more efficient routing strategies for the Internet.

Interactions between climate and the rise of explosive volcanic plumes : a new feedback in the Earth system.
Creators: name: Aubry, Thomas J.
Publisher: name: University of British Columbia

description: Volcanic plumes rising above the tropopause inject SO₂ directly into the stratosphere, where it forms sulfate aerosols that modulate Earth’s radiative balance. Stratospheric volcanic sulfate aerosol forcing reduces Earth’s surface temperature and is a predominant driver of climate variability. The processes that govern the volcanic injection of SO₂ into the stratosphere are controlled to a large extent by climate. Thus, climate changes may affect stratospheric volcanic SO₂ inputs, volcanic forcing and climate, in turn. The assessment of this potential feedback is hindered by difficulties in understanding and constraining observationally the key processes governing plume rise. To address this challenge, we compile a new exhaustive database of eruption source parameters, along with their uncertainties (Aubry et al., 2017b). We apply these data along with the results of laboratory experiments to compare the performances of our newly proposed and published scalings for predicting volcanic plume heights. We demonstrate that plume heights are captured better by scalings accounting for atmospheric conditions (Aubry et al., 2017b). Furthermore, we evaluate 1D models of volcanic plume using the experimental and natural eruption datasets. We show that these new datasets enable reliable constraints on processes critical to plume rise including the rate of entrainment of atmosphere as well as the role condensation of water vapor (Aubry et al. (2017a) and Chapter 4). Significant limitations in the compiled data remain and we identify future improvements required to improve plume models evaluation. Next, we explore the impacts of climate projections for ongoing global warming on the rise height of volcanic plumes and SO₂ injection into the stratosphere. Our results reveal a novel feedback where global warming will reduce stratospheric injections of SO₂ by explosive eruptions (Aubry et al., 2016). This would lead to reduced volcanic forcing and surface cooling, and enhance global warming, in turn. To test this feedback, we develop a new idealized model of volcanic aerosol forcing and show that the proposed feedback may have important implications if greenhouse gas concentrations continue to increase at currents rates (Chapter 6). An exciting future direction is to assess interactions among the proposed feedback with other published climate-volcano feedbacks.

description: This paper explores the transformative potential of integrating Artificial Intelligence (AI) with established cybersecurity frameworks such as the Cybersecurity Maturity Model Certification (CMMC) and the National Institute of Standards and Technology (NIST) Special Publication 800-171. The thesis argues that the relationship between AI and these frameworks has the capacity to transform risk management in cybersecurity, where it could serve as a critical element in threat mitigation. In addition to addressing AI’s capabilities, this paper acknowledges the risks and limitations of these systems, highlighting the need for extensive research and monitoring when relying on AI. One must understand boundaries when integrating AI into frameworks that ensure the security of sensitive data, otherwise, the ethicality of AI systems is compromised. This paper overviews compliance audits and their intricate relationship with cybersecurity frameworks CMMC and NIST 800-171, underscoring their complementary nature and shared objectives. Finally, the significance of AI in ensuring compliance with these frameworks will be explored, and the transformative potential of AI in automating processes and its advancements in risk management will be discussed.

description: The federal government has pledged to update Canada's development assistance (ODA) policy and this paper examines the important role of remittances in the development program. Remittances can serve as a significant form of cross-border capital flows and can have sizable effects on both the sending and receiving countries. This policy piece provides an overview of trends in global remittances and gives a context for the policy discussion on the relationship between remittances and ODA. The paper draws from the authors’ expertise and presents a background on the primary reasons behind global remittances and their impacts on other countries including the United States, Mexico, Nepal and Kenya. Within the context of Canada, the paper also examines how remittances have been able to complement and possibly drive other development reform efforts domestically and abroad.  The goal of the analysis is to help inform the policy discussion in Canada and concludes with a set of policy recommendations for the Canadian federal government.
