description: Optimistic parallelization is a promising approach for the parallelization of irregular algorithms: potentially interfering tasks are launched dynamically, and the runtime system detects conflicts between concurrent activities, aborting and rolling back conflicting tasks. However, parallelism in irregular algorithms is very complex. In a regular algorithm like dense matrix multiplication, the amount of parallelism can usually be expressed as a function of the problem size, so it is reasonably straightforward to determine how many processors should be allocated to execute a regular algorithm of a certain size (this is called the processor allocation problem). In contrast, parallelism in irregular algorithms can be a function of input parameters, and the amount of parallelism can vary dramatically during the execution of the irregular algorithm. Therefore, the processor allocation problem for irregular algorithms is very difficult. In this paper, we describe the first systematic strategy for addressing this problem. Our approach is based on a construct called the conflict graph, which (i) provides insight into the amount of parallelism that can be extracted from an irregular algorithm, and (ii) can be used to address the processor allocation problem for irregular algorithms. We show that this problem is related to a generalization of the unfriendly seating problem and, by extending Turán's theorem, we obtain a worst-case class of problems for optimistic parallelization, which we use to derive a lower bound on the exploitable parallelism. Finally, using some theoretically derived properties and some experimental facts, we design a quick and stable control strategy for solving the processor allocation problem heuristically.

Fundamental aspects of thiosulfate leaching of silver sulfide in the presence of additives
Creators: name: Deutsch, Jared Luke
Publisher: name: University of British Columbia
Year: 2012

description: Thiosulfate is a promising alternative for leaching silver sulfide ores such as those at the epithermal Yanacocha deposit. These ores suffer from low silver recovery, high mercury extraction and environmental challenges when treated with conventional cyanide. In this study, cupric-ammonia, ferric-ethylenediaminetetraacetic acid (EDTA), ferric-oxalate and ferric-citrate are tested with thiosulfate in a series of rotating disk experiments with silver sulfide and with ore from Yanacocha. This thesis publishes experimental evidence that supports the use of thiosulfate with different additives as a potential alternative to conventional cyanidation for silver sulfide leaching. The leaching of silver sulfide by cupric-ammonia thiosulfate can occur either by the substitution of cupric or cuprous for silver. The cupric catalyzed reaction is favored due to a thermodynamic barrier to the cuprous reaction. Rotating disk experiments demonstrate that cupric-ammonia leaching is under mixed chemical/diffusion control. The leaching rate is maximized by stabilizing cupric in solution with ammonia and increasing the availability of thiosulfate for silver dissolution. The addition of EDTA to this system decreased the leaching rate of the silver sulfide disk by lowering the cupric reactivity, but accelerated silver leaching of the ore, likely due to the prevention of passive oxide film formation on sulfides. Ferric complexes used were found to be very unreactive towards thiosulfate, but are reduced by sulfides present in the ore. Ferric-EDTA was the most effective oxidant of the three for leaching silver sulfide with thiosulfate. Silver recovery of the ground ore in batch leaching tests is low due to quartz locking of silver, with cupric-ammonia and ferric-EDTA leaches exposed to air recovering 31% and 26% after 24 hours, respectively. Cyanidation recovered 34% silver with a 95% confidence interval of 28-37%. The slightly lower recovery by thiosulfate may be due to silver minerals which are not amenable to thiosulfate leaching.

description: Previous research has revealed differences in the experience of negative consequences and the likelihood of help-seeking relative to a gambler’s preferred mode of play (i.e., exclusively online, exclusively offline, and mixed-mode). Little research has identified and compared mixed-mode gamblers to exclusively online and offline gamblers, and although stigma has been recognized as a common barrier to seeking help for disordered gambling, there is a paucity of research that has examined the relationship between stigma and disordered gambling. Thus, the primary goal of the present study was to examine relationships between preferred gambling mode, gambling-related stigma, and help-seeking behaviours in a sample of disordered gamblers. A total of N = 517 disordered gamblers (n = 166 online gamblers, n = 171 offline gamblers, and n = 180 mixed-mode gamblers) completed measures related to their past six-month gambling behaviours, lifetime decision to seek help, endorsement of perceived and experienced stigma, and coping orientations toward gambling-related stigma. Results showed that (a) compared to offline gamblers, mixed-mode gamblers reported worse disordered gambling severity and a greater number of gambling-related harms; (b) the likelihood of lifetime help-seeking did not differ between groups; (c) among mixed-mode gamblers, secrecy and withdrawal coping orientations were negative and positive predictors of help-seeking, respectively; (d) a willingness to educate people about the realities of having gambling problems was predictive of help-seeking among offline gamblers; and (e) experienced stigma was a positive predictor of help-seeking, regardless of preferred gambling mode. Possible reasons for differences in help-seeking predictors and implications of this research are discussed.

In this paper, we show that Jacquet-Shalika integral attains a certain L-function, so called the formal exterior square L-function, when the Whittaker function is associated to a newform for $π$. By consideration on the Galois side, formal exterior square L-functions are equal to exterior square L-functions for some principal series representations.

description: The aim of this study was to develop a method that would identify the cluster centroids and the optimal number of clusters for a given sensitivity level and could work equally well for the different sequence datasets. A novel method that combines the linear mapping hash function and multiple sequence alignment (MSA) was developed. This method takes advantage of the already sorted by similarity sequences from the MSA output, and identifies the optimal number of clusters, clusters cut-offs, and clusters centroids that can represent reference gene vouchers for the different species. The linear mapping hash function can map an already ordered by similarity distance matrix to indices to reveal gaps in the values around which the optimal cut-offs of the different clusters can be identified. The method was evaluated using sets of closely related (16S rRNA gene sequences of Nocardia species) and highly variable (VP1 genomic region of Enterovirus 71) sequences and outperformed existing unsupervised machine learning clustering methods and dimensionality reduction methods. This method does not require prior knowledge of the number of clusters or the distance between clusters, handles clusters of different sizes and shapes, and scales linearly with the dataset. The combination of MSA with the linear mapping hash function is a computationally efficient way of gene sequence clustering and can be a valuable tool for the assessment of similarity, clustering of different microbial genomes, identifying reference sequences, and for the study of evolution of bacteria and viruses.

description: We investigate nonequilibrium phase transitions in the presence of disorder that locally breaks the symmetry between two equivalent macroscopic states. In low-dimensional equilibrium systems, such "random-field" disorder is known to have dramatic effects: It prevents spontaneous symmetry breaking and completely destroys the phase transition. In contrast, we demonstrate that the phase transition of the one-dimensional generalized contact process persists in the presence of random field disorder. The dynamics in the symmetry-broken phase becomes ultraslow and is described by a Sinai walk of the domain walls between two different absorbing states. We discuss the generality and limitations of our theory, and we illustrate our results by means of large-scale Monte-Carlo simulations.

Product Returns

description: In this paper, we investigate the assortment planning decisions of a retailer that operates an online sales channel and a brick-and-mortar store simultaneously. We consider the impact of product returns, which is a norm in retailing but also a factor for lost profit, explicitly. Assortment decisions impact the product returns because customers who shop online after visiting a physical store does not have complete information about the products that are not showcased in the physical store since the customer cannot experience the product before purchase. Our results indicate that the retailer prefers some level of inaccuracy in customers' online utility evaluation, rather than a perfect evaluation. Moreover, in case of consistent inaccuracy, customers always prefer to return an item with lower price. Furthermore, there are cases where it is optimal to not fully use all the available capacity.
Spontaneous formation of permanent shear bands in a mesoscopic model of flowing disordered matter

description: This study proposes a coherent scenario of the formation of permanent shear bands in the flow of yield stress materials. It is a well accepted point of view that flow in disordered media is occurring via local plastic events, corresponding to small size rearrangements, that yield a long range stress redistribution over the system. Within a minimalistic mesoscopic model that incorporates these local dynamics, we study the spatial organisation of the local plastic events. The most important parameter in this study is the typical restructuring time needed to regain the original structure after a local rearrangement. In agreement with a recent mean field study [Coussot \textit{et al., Eur. Phys. J. E}, 2010, \textbf{33}, 183] we observe a spontaneous formation of permanent shear bands, when this restructuring time is large compared to the typical stress release time in a rearrangement. The bands consist of a large number of plastic events within a solid region that remains elastic. This heterogeneous flow behaviour is different in nature from the transient dynamical heterogeneities that one observes in the small shear rate limit in flow without shear-banding [Martens \textit{et al., Phys. Rev. Lett.}, 2011, \textbf{106}, 156001]. We analyse in detail the dependence of the shear bands on system size, shear rate and restructuring time. Further we rationalise the scenario within a mean field version of the spatial model, that produces a non monotonous flow curve for large restructuring times. This explains the instability of the homogeneous flow below a critical shear rate, that corresponds to the minimum of the curve. Our study therefore strongly supports the idea that the characteristic time scales involved in the local dynamics are at the physical origin of permanent shear bands.

description: The intra- and inter-species genetic diversity of bacteria and the absence of 'reference', or the most representative, sequences of individual species present a significant challenge for sequence-based identification. The aims of this study were to determine the utility, and compare the performance of several clustering and classification algorithms to identify the species of 364 sequences of 16S rRNA gene with a defined species in GenBank, and 110 sequences of 16S rRNA gene with no defined species, all within the genus Nocardia. A total of 364 16S rRNA gene sequences of Nocardia species were studied. In addition, 110 16S rRNA gene sequences assigned only to the Nocardia genus level at the time of submission to GenBank were used for machine learning classification experiments. Different clustering algorithms were compared with a novel algorithm or the linear mapping (LM) of the distance matrix. Principal Components Analysis was used for the dimensionality reduction and visualization. Results: The LM algorithm achieved the highest performance and classified the set of 364 16S rRNA sequences into 80 clusters, the majority of which (83.52%) corresponded with the original species. The most representative 16S rRNA sequences for individual Nocardia species have been identified as 'centroids' in respective clusters from which the distances to all other sequences were minimized; 110 16S rRNA gene sequences with identifications recorded only at the genus level were classified using machine learning methods. Simple kNN machine learning demonstrated the highest performance and classified Nocardia species sequences with an accuracy of 92.7% and a mean frequency of 0.578.
Jane Austen's free indirect style : a linguistic ethnography

description: This study assesses the relationship between the diffusion of free indirect discourse and the decline of the British epistolary novel in the late-eighteenth and early-nineteenth centuries. Studying the works of a single stylist, Jane Austen, and her engagement with the mobility of the letter genre at the turn of the century, it synthesizes literary-historical, linguistic, and narratological perspectives on discourse representation in order to evaluate claims that Austen was the “pioneer” of this free indirect style, and to comment on how her simultaneous shift in genre from the first-person epistolary mode to third-person classical realism informs that style’s development.

description: Introduction: Cancer survivors commonly report deterioration in cognitive function during and for several years following cancer treatment, adversely affecting their quality of life. Cognitive changes in cancer survivors likely occur due a complex interaction of disease-related, treatment-related, and psychological factors. One promising intervention for alleviating disruptions in cognitive function in cancer survivors is Mindfulness-Based Cancer Recovery (MBCR). Methods: A systematic review examined the effects of mindfulness-based interventions (MBIs) on cognitive function in cancer survivors. An observational study included 38 breast and colorectal cancer survivors to investigate predictors of self-reported and objectively-assessed cognitive function before chemotherapy treatment. Finally, an intervention study including 38 breast and colorectal cancer survivors investigated the effects of participating in an online MBCR group during (immediate group) or after (waitlist group) chemotherapy treatment in self-reported and objectively-assessed cognitive function. Results: Results of the systematic review indicated significant effects on self-reported cognitive function, favouring MBIs over inactive controls (e.g., waitlist, usual care) and active controls (e.g., metacognition training, walking groups). Mixed results were reported for objectively-assessed cognitive function. Results of the observational study indicated that mood disturbance was a significant predictor of self-reported cognitive function. Objectively-assessed cognitive function was not significantly correlated with other unwanted side effects. Results of the intervention study indicated an average worsening of self-reported cognitive function from pre- to post-MBCR/post-waiting regardless of group assignment. Small to large within-person and between-group effects were observed across timepoints for objectively-assessed cognitive function. Differences in objectively-assessed cognitive function across time were not statistically significant. Conclusion: Future research is warranted to further investigate the role of MBIs in improving both self-reported and objectively-assessed cognitive function in cancer survivors undergoing treatment. In particular, there is a need for studies adequately powered to detect cognitive changes between groups over time, using a range of cognitive assessment methods, with diverse samples.

description: In the internal shock model of gamma ray bursts ultrahigh energy muons, pions, neutrons and kaons are likely to be produced in the interactions of shock accelerated relativistic protons with low energy photons (KeV-MeV). These particles subsequently decay to high energy neutrinos/antineutrinos and other secondaries. In the high internal magnetic fields of gamma ray bursts, the ultrahigh energy charged particles ($μ^+$, $π^+$, $K^+$) lose energy significantly due to synchrotron radiations before decaying into secondary high energy neutrinos and antineutrinos. The relativistic neutrons decay to high energy antineutrinos, protons and electrons. We have calculated the total neutrino flux (neutrino and antineutrino) considering the decay channels of ultrahigh energy muons, pions, neutrons and kaons. We have shown that the total neutrino flux generated in neutron decay can be higher than that produced in $μ^+$ and $π^+$ decay. The charged kaons being heavier than pions, lose energy slowly and their secondary total neutrino flux is more than that from muons and pions at very high energy. Our detailed calculations on secondary particle production in $pγ$ interactions give the total neutrino fluxes and their flavour ratios expected on earth. Depending on the values of the parameters (luminosity, Lorentz factor, variability time, spectral indices and break energy in the photon spectrum) of a gamma ray burst the contributions to the total neutrino flux from the decay of different particles (muon, pion, neutron and kaon) may vary and they would also be reflected on the neutrino flavour ratios.

description: Apart from cost, major challenges facing the recovery of bitumen from Canadian oil sands are the amount of energy utilized per volume of bitumen recovered as well as the amount of greenhouse gas (GHG) emitted to the environment. The situation is even worse in reservoirs that are considered to be challenging or difficult-to-produce due to the reservoir geology. Steam-assisted gravity drainage (SAGD) is the primary in-situ recovery technique for bitumen recovery in Northern Alberta, Western Canada. Within the reservoir, steam chamber conformance is a major control on the efficiency, economic performance, and GHG emissions intensity of the process. There is a search for ways to significantly reduce the costs and emissions of SAGD. Multilateral wells possess the potential to contribute towards this goal. To date, different theoretical designs of multilateral wells have been proposed in literature. One of the most common designs studied is the fishbone well configuration. This configuration has large reservoir contact and thus enhances the productivity of the well. While the merits of the application of multilateral wells are well documented in lighter oil systems, an understanding of the best operating conditions for the use in oil sands reservoirs is poorly understood. The research documented in this thesis examines in detail how fishbone multilateral wells can be used to improve the performance of SAGD. In summary, the results demonstrate that fishbone well are able to improve steam chamber conformance and ultimately minimize cumulative steam-oil ratio (cSOR), maximize ultimate bitumen recovery, improve net present value (NPV), and reduce GHG emissions. Therefore, fishbone multilateral wells should be considered for future SAGD operations.

description: Background These last decades have seen the emergence and development of cell-based therapies, notably those based on mesenchymal stromal cells (MSCs). The advancement of these promising treatments requires increasing the throughput of processed cell for industrialization in order to reduce production costs. Among the various bioproduction challenges, downstream processing (DSP), including medium exchange, cell washing, cell harvesting and volume reduction, remains a critical step on which improvements are needed. Typically, these processes are performed by centrifugation. However, this approach limits the automation, especially in small batch productions where it is performed manually in open system. Methods An acoustophoresis-based system was developed for cell washing. The cells were transferred from one stream to another via the acoustic forces and were collected in a different medium. The optimal flow rates of the different streams were assessed using Red Blood Cells (RBCs) suspended in an albumin solution. Finally, the impact of acoustic washing on adipose tissue-derived MSCs (AD-MSCs) transcriptome was investigated by RNA-sequencing. Results With a single passage through the acoustic device at input flow rate of 45 mL/h, the albumin removal was up to 90% while recovering 99% of RBCs. To further increase the protein removal, a loop washing in two steps was performed and has allowed an albumin removal $\ge$99% and a RBCs/AD-MSCs recovery of 99%. After loop washing of AD-MSCs, only 2 genes, HES4 and MIR-3648-1, were differently expressed compared to the input. Conclusion In this study, we developed a continuous cell washing system based on acoustophoresis. The process allows a high cell throughput while inducing little gene expression changes. These results highly suggest that cell washing based on acoustophoresis is a relevant and promising solution for numerous applications in cell manufacturing.

description: Diagnostic Fracture Injection Tests (DFIT), are commonly used to derive key parameters for hydraulic fracture design and modeling. Although this process can identify properties needed for well optimization, it is also time intensive, affected by interpretation bias, and incomplete data. In this thesis, I address these adversities by applying unsupervised clustering methods: K-Means, DB-Scan, Hierarchical modeling, and Gaussian mixture models to identify point density variation that correlates to key parameters on a DFIT pressure decline. Deep Neural networks (DNN) trained using labeled DFITs are further tested for event prediction. To test these methods a variety of platforms are tested such as R-Studio Shiny Web App® to create user-friendly testing platforms and Python® for its computational ability when faced with supervised learning methods. Collectively unsupervised and supervised learning methods show significant promise in the DFIT interpretation realm.
Second-order hyperbolic Fuchsian systems. Asymptotic behavior of geodesics in Gowdy spacetimes

description: Recent work by the authors led to the development of a mathematical theory dealing with `second--order hyperbolic Fuchsian systems', as we call them. In the present paper, we adopt a physical standpoint and discuss the implications of this theory which provides one with a new tool to tackle the Einstein equations of general relativity (under certain symmetry assumptions). Specifically, we formulate the `Fuchsian singular initial value problem' and apply our general analysis to the broad class of vacuum Gowdy spacetimes with spatial toroidal topology. Our main focus is on providing a detailed description of the asymptotic geometry near the initial singularity of these inhomogeneous cosmological spacetimes and, especially, analyzing the asymptotic behavior of timelike geodesics ---which represent the trajectories of freely falling observers --- and null geodesics. In particular, we numerically construct Gowdy spacetimes which contain a black hole--like region together with a flat Minkowski--like region. By using the Fuchsian technique, we investigate the effect of the gravitational interaction between these two regions and we study the unexpected behavior of geodesic trajectories within the intermediate part of the spacetime limited by these two regions.

description: The eyes present us with a window through which we view the world and gather information. Eye-gaze tracking systems are the means by which a user's point of gaze (POG) can be measured and recorded. Despite the active research in gaze tracking systems and major advances in this field, calibration remains one of the primary challenges in the development of eye tracking systems. In order to facilitate gaze measurement and tracking, eye-gaze trackers utilize simplifications in modeling the human eye. These simplifications include using a spherical corneal model and using population averages for eye parameters in place of individual measurements, but use of these simplifications in modeling contribute to system errors and impose inaccuracies on the process of point of gaze estimation. This research introduces a new one-time per-user calibration method for gaze estimation systems. The purpose of the calibration method developed in this thesis is to calculate and estimate different individual eye parameters based on an aspherical corneal model. Replacing average measurements with individual measurements promises to improve the accuracy and reliability of the system. The approach presented in this thesis involves estimating eye parameters by statistical modeling through least squares curve fitting. Compared to a current approach referred to here as the Hennessey's calibration method, this approach offers significant advantages, including improved, individual calibration. Through analysis and comparison of this new calibration method with the Hennessey calibration method, the research data presented in this thesis shows an improvement in gaze estimation accuracy of approximately 27%. Research has shown that the average accuracy for the Hennessey calibration method is about 1:5 cm on an LCD screen at a distance of 60 cm, while the new system, as tested on eight different subjects, achieved an average accuracy of 1:1 cm. A statistical analysis (T-test) of the comparative accuracy of the new calibration method versus the Hennessey calibration method has demonstrated that the new system represents a statistically significant improvement.

A Serological Assessment and Development of a Microbiome and Virome Analysis in Beef Calves

description: Bovine Respiratory Disease Complex (BRDC) is a multifactorial disease and the leading cause of morbidity and mortality on feedlots. In many instances, metaphylactic administration of antimicrobials is used to both treat and prevent BRDC. However, this practice is becoming less sustainable due to increasing antimicrobial resistance. Therefore, methods such as preconditioning are being explored to reduce BRDC incidence and the associated antimicrobial use. Preconditioning includes aspects such as fence line weaning and a strategic vaccination schedule to prepare cattle for life on the feedlot. The serological component of this study aimed to demonstrate a higher proportion of preconditioned (PC) animals would arrive on the feedlot with antibodies present than their auction derived (AD) and ranch-sourced (RS) counterparts. The vaccination protocol was evaluated by collecting serum samples from PC, AD, and RS calves upon arrival at the feedlot. Enzyme-linked immunosorbent assays were used to detect antibodies against viral BRDC-associated pathogens: Bovine Viral Diarrhoea Virus, Infectious Bovine Rhinotracheitis, Bovine Parainfluenza Virus Type 3, Bovine Respiratory Syncytial Virus, and Bovine Coronavirus (BoCoV). Significant differences were only found between PC and AD calves as well as PC and RS calves for BoCoV. A metatranscriptomics pilot study was also included in this work to determine optimal downstream processing of deep nasal swabs (DNS). Four PC calves that showed signs of BRDC during preconditioning were utilized in the pilot study. A total RNA isolation was performed on DNS before samples were divided in two, creating an “A” and “B” for each sample. “A” samples underwent rRNA depletion and poly-A tailed mRNA depletion. While “B” samples only had rRNA depleted. Results were interpreted through two bioinformatic alignment tools MetPhlAn3 and Kaiju. MetPhlAn3 identified a total of 20 species, while Kaiju identified over 5000. However, Kaiju also had a significantly high rate of false-positive when reporting positive controls; therefore, results from Kaiju must be interpreted with a high degree of caution. Data from both ELISA’s and the pilot study can provide insight for future directions for this project and, in doing so, support preconditioning as a viable method for the prevention of BRDC.
Coherence Enhanced Transient Lasing in XUV Regime

description: We report the effect of a coherent drive on transient lasing in three-level $Λ$ and $Ξ$ configurations ($c\leftrightarrow a\leftrightarrow b$). We show that the presence of a resonant coherent drive on the $a\leftrightarrow c$ optical transition can yield an order of magnitude enhancement of the output laser energy on a $a\rightarrow b$ XUV or X-ray transition than with no coherent drive. We demonstrate the crucial role of coherence $\varrho_{ac}$ for the laser power enhancement. Contrary to the forward direction (with respect to the pump), where forward gain can be enhanced for some choice of the drive Rabi frequency $Ω_{c}$, coherent drive on the $ac$ transition always suppresses the backward gain.

Affine GARCH option pricing models, stochastic interest rates, and diffusion limits

description: This article proposes a derivative pricing framework when the asset returns and the short term rate process are modelled with affine GARCH models driven by correlated Gaussian innovations. The risk neutral dynamics are derived based on a co-variance dependent pricing kernel and semi-closed form solutions are derived for European style options and bond prices. We further derive the weak diffusion limits of the underlying processes under both physical and risk-neutral measure and we investigate the consistency between the proposed pricing kernel with the well-known Girsanov principle in continuoustime. A variety of numerical exercises are provided to analyze the validity of our pricing formulae, the sensitivity of the option prices relative to the pricing kernel parameters, and the convergence of option prices to those based on the limiting diffusions. Finally, we illustrate an empirical analysis based on a joint estimation using historical asset returns and short-term rates, and cross sections of options and bond prices.
