description: As a newly emergent sport, Rock .Paper Scissors (RPS) has been an under-researched area of study in the sociology of sport. Individuals who are involved with RPS in one capacity or another can be seen to have entered into a contested terrain that challenges previously conceived notions of sport, lifestyle sport, subculture, and 'adulthood'. The result is a complex negotiation of play (in the most pure and child-like sense of the term) and sport both at the theoretical level between resistance and incorporation, and in the lived experiences of those involved in the RPS subculture. This can be seen while RPS subculture members negotiate with and reconcile ideas (and ideologies) of sport, play, and the notion of 'rejuvenile'. Using a cultural studies perspective, multiple methods were used (including semi-structured interviews, and observation) to understand the unique characteristics that have come to define and distinguish the sport of RPS and its respective subculture.

description: DisSLib:CC (Distributed Search Library: Common Central) is a library for creating distributed search systems. It allows developers to take advantage of the now common access to multi­ple processors, either as part of a multi-core processor in a single machine or part of a cluster of computational power that exists around us. Some software can take advantage of this new configuration of hardware without a lot of extra work, but some software needs special consid­eration to get benefits from multiple processors, especially knowledge based search. Knowledge-based search allows us to find good solutions to hard problems, it combines knowledge about how to solve problems and knowledge about the problems that need to be solved with the raw processing power of a computer. In knowledge-based search systems solutions are found by taking small computational steps, some of which may be in the right di­rection and some of which may be wrong. Because of these small steps and the need to evaluate what was a good choice simply spreading these steps across multiple processors without a plan does not work. Fortunately there are paradigms for distributed knowledge-based search that let us use multiple processors to speed search up. Given the universality of these paradigms, it is possible to use them to design libraries that let developers create distributed search systems. DisSLib:CC was created to allow developers to build distributed search systems that solve their problems as quickly as possible without having to do the hard parts of handling commu­nications and the repetitive parts handling configuration and writing logs and search protocols. DisSLib:CC allows developers to create distributed search systems from sequential search sys­tems with minimal extra code. Two systems developed using DisSLib:CC were used to test some aspects of the configuration of distributed search systems and showed speed ups based on finding the right conditions.
The ambiguity of violence : ideology, state, and religion in the late Chosŏn dynasty

Publisher: name: University of British Columbia
Year: 2011

description: My dissertation focuses on the violence associated with two Korean Catholics from the late Chosŏn dynasty. My first subject, Alexius Hwang Sayŏng, wrote a letter during the anti-Catholic suppression of 1801 to the bishop of Beijing proposing that a Western armada invade Korea to force the Chosŏn state to tolerate Catholicism, only to be arrested and executed for treason. In 1909, my second subject, Thomas An Chunggŭn, assassinated Itō Hirobumi, the first resident-general of Korea, in hopes that his death would lead to the restoration of Korean independence. Through the study of their writings, interrogation reports, court records, public pronouncements, newspapers, missionary letters and journals, I reveal the different types of violence they sought to justify, suffered, and were reacting to. While Hwang and Neo-Confucian officials both believed that violence could be legitimately deployed in order to actualize the worldviews mandated by their respective religions, the centrality of religion had largely been eclipsed by the secular ideologies of nationalism, Social-Darwinism, and Pan-Asianism, by An’s time. This situation led to a struggle within and between An and foreign missionaries over the proper relationship between nation, state, and religion, and eventually to An’s decision to kill Itō for both religious and secular reasons, even as the Catholic Church forbade violent resistance to Japan’s colonial project. Through a comparison of the violence associated with Hwang and An, I show that religion can both encourage and discourage violence at the same time, and that its influence can be shaped, magnified, or diminished by secular worldviews, proving the difficulty in simply labeling violence as “religious” or “secular,” and the essentially ambiguous nature of violence. I therefore propose that, in contravention to scholars who argue that religion is somehow more violent than secular ideologies, it is not so much whether a type of violence can be labeled as secular or religious, but the contents of that worldview, its relationship with other worldviews within an individual, and the historical context in which it is actualized, that is more important in determining its propensity for violence.

description: With the advent of the Gaia data, the unprecedented kinematic census of great part of the Milky Way disc will allow us to characterise the local kinematic groups and new groups in different disc neighbourhoods. First, we show here that the models predict a stellar kinematic response to the spiral arms and bar strongly dependent on disc position. For example, we find that the kinematic groups induced by the spiral arm models change significantly if one moves only ~ 0.6 kpc in galactocentric radius, but ~ 2 kpc in azimuth. There are more and stronger groups as one approaches the spiral arms. Depending on the spiral pattern speed, the kinematic imprints are more intense in nearby vicinities or far from the Sun. Secondly, we present a preliminary study of the kinematic groups observed by RAVE. This sample will allow us, for the first time, to study the dependence on Galactic position of the (thin and thick) disc moving groups. In the solar neighbourhood, we find the same kinematics groups as detected in previous surveys, but now with better statistics and over a larger spatial volume around the Sun. This indicates that these structures are indeed large scale kinematic features.

description: The Graph Convolutional Networks (GCNs) have achieved excellent results in node classification tasks, but the model's performance at low label rates is still unsatisfactory. Previous studies in Semi-Supervised Learning (SSL) for graph have focused on using network predictions to generate soft pseudo-labels or instructing message propagation, which inevitably contains the incorrect prediction due to the over-confident in the predictions. Our proposed Dual-Channel Consistency based Graph Convolutional Networks (DCC-GCN) uses dual-channel to extract embeddings from node features and topological structures, and then achieves reliable low-confidence and high-confidence samples selection based on dual-channel consistency. We further confirmed that the low-confidence samples obtained based on dual-channel consistency were low in accuracy, constraining the model's performance. Unlike previous studies ignoring low-confidence samples, we calibrate the feature embeddings of the low-confidence samples by using the neighborhood's high-confidence samples. Our experiments have shown that the DCC-GCN can more accurately distinguish between low-confidence and high-confidence samples, and can also significantly improve the accuracy of low-confidence samples. We conducted extensive experiments on the benchmark datasets and demonstrated that DCC-GCN is significantly better than state-of-the-art baselines at different label rates.

description: We report a multisite photometric campaign for the Beta Cep stars V2052 Oph and V986 Oph. 670 hours of high-quality differential photoelectric Stromgren, Johnson and Geneva time-series photometry were obtained with eight telescopes on five continents during 182 nights. Frequency analyses of the V2052 Oph data enabled the detection of three pulsation frequencies, the first harmonic of the strongest signal, and the rotation frequency with its first harmonic. Pulsational mode identification from analysing the colour amplitude ratios confirms the dominant mode as being radial, whereas the other two oscillations are most likely l=4. Combining seismic constraints on the inclination of the rotation axis with published magnetic field analyses we conclude that the radial mode must be the fundamental. The rotational light modulation is in phase with published spectroscopic variability, and consistent with an oblique rotator for which both magnetic poles pass through the line of sight. The inclination of the rotation axis is 54o

Violation of Leggett-Garg inequalities in quantum measurements with variable resolution and back-action

description: Quantum mechanics violates Leggett-Garg inequalities because the operator formalism predicts correlations between different spin components that would correspond to negative joint probabilities for the outcomes of joint measurements. However, the uncertainty principle ensures that such joint measurements cannot be implemented without errors. In a sequential measurement of the spin components, the resolution and back-action errors of the intermediate measurement can be described by random spin flips acting on an intrinsic joint probability. If the error rates are known, the intrinsic joint probability can be reconstructed from the noisy statistics of the actual measurement outcomes. In this paper, we use the spin-flip model of measurement errors to analyze experimental data on photon polarization obtained with an interferometric setup that allows us to vary the measurement strength and hence the balance between resolution and back-action errors. We confirm that the intrinsic joint probability obtained from the experimental data is independent of measurement strength and show that the same violation of the Leggett-Garg inequality can be obtained for any combination of measurement resolution and back-action.

description: We derive a Dirac-like equation, the asymmetric Dirac equation, where particles and antiparticles sharing the same wave number have different energies and momenta. We show that this equation is Lorentz covariant under proper Lorentz transformations (boosts and spatial rotations) and also determine the corresponding transformation law for its wave function. We obtain a formal connection between the asymmetric Dirac equation and the standard Dirac equation and we show that by properly adjusting the free parameters of the present wave equation we can make it reproduce the predictions of the usual Dirac equation. We show that the rest mass of a particle in the theoretical framework of the asymmetric Dirac equation is a function of a set of four parameters, which are relativistic invariants under proper Lorentz transformations. These four parameters are the analog to the mass that appears in the standard Dirac equation. We prove that in order to guarantee the covariance of the asymmetric Dirac equation under parity and time reversal operations (improper Lorentz transformations) as well as under the charge conjugation operation, these four parameters change sign in exactly the same way as the four components of a four-vector. The mass, though, being a function of the square of those parameters remains an invariant. We also extensively study the free particle plane wave solutions to the asymmetric Dirac equation and derive its energy, helicity, and spin projection operators as well as several Gordon's identities. The hydrogen atom is solved in the present context after applying the minimal coupling prescription to the asymmetric Dirac equation, which also allows us to appropriately obtain its non-relativistic limit.

Ict systems in the post 9/11 context: a comparative US/Canada soft system analysis

Year: 2011

description: Bibliography: p. 352-379
description: This dissertation is a document based analysis of the major social and technology factors involved in developing Canada' s post 9/ 11 response and national integrated security system. The role of ICT (information and communication technology) systems is of special interest. There is a paucity of academic research of Canadian post 9/11 federal responses apart from a narrow focus on the major moves announced, even though the impact extends far beyond these. 9/11 occurred against a background of technological advances and ICT systems already presenting the Canadian federal government with policy, regulatory and legislative challenges profoundly important in shaping the Canadian federal response. These have not received sufficient academic study. A substantial part of Canada's federal post 9/11 national security agenda plays out through ICT systems and the underlying layer of information. This research analyzes actual or intended Canadian federal government action (according to official publicly available documents), and also goes deeper to analyze the role of ICT and information. Significantly, it positions both in Canadian historical and current contexts and includes the central but missing element: information. The research establishes the baseline of soft system components (legislation, institutional organization and strategy) Canada had to draw upon in its post 9/1 1 response. Federal processes for civil defence were established in World War II and the Cold War, and these were brought forward into the post 9/11 context. The research also establishes points in the US homeland security agenda relevant to Canada (according to each country's official publicly available documents). In the aftermath of 9/11 the US federal focus firmly fixed on information, and this has not waivered. ICT systems and ICT critical infrastructure are primary targets for information capture to serve the evolving and expanding homeland security agenda. Canada responded to the US responses to the terrorist attacks, and information is also the central feature of the Canadian response. A major conclusion reached is the post 9/11 Canadian federal integrated security system encompasses not only the announced system, but also a number of other systems. These include hidden and shadow systems, and unannounced and backdoor systems. All involve ICT and information.

description: Despite the fundamental progress in autonomous molecular and materials discovery, data scarcity throughout chemical compound space still severely hampers the use of modern ready-made machine learning models as they rely heavily on the paradigm, 'the bigger the data the better'. Presenting similarity based machine learning (SML), we show an approach to select data and train a model on-the-fly for specific queries, enabling decision making in data scarce scenarios in chemistry. By solely relying on query and training data proximity to choose training points, only a fraction of data is necessary to converge to competitive performance. After introducing SML for the harmonic oscillator and the Rosenbrock function, we describe applications to scarce data scenarios in chemistry which include quantum mechanics based molecular design and organic synthesis planning. Finally, we derive a relationship between the intrinsic dimensionality and volume of feature space, governing the overall model accuracy.

description: In this thesis, several outstanding problems in sketch-based interfaces for 3d modeling (SBIM) are addressed in two major areas of focus: understanding and identifying the components of a complex sketch (analysis), and using those identified components to construct a 3d model (interpretation). Unlike previous approaches that assume simple or rigorously constrained input sketches, the goal in this research was to support natural, unconstrained sketching with many pen strokes. An image-based tracing method is used to blend the input and extract salient strokes, followed by a stroke classification method that captures how the strokes define the boundary, regions, and features of objects. Unconstrained sketches that contain numerous strokes of different classes require a new approach to mesh construction. A feature-based method is proposed to embed all input lines into the underlying geometry. Furthermore, using an initial sparse triangulation followed by a subdivide-and-snap approach results in an output mesh with subdivision connectivity. By offering a direct connection between the sketch and the underlying geometry, the output is suitable for further refinement and use in later parts of the modeling pipeline. This construc­tion enables a set of feature-based annotations, in which the user specifies the cross-section, holes, bumps, and extrusions by marking up a sketch with simple, evocative gestures. These advancements are united in an image-assisted interface in which user-provided images are used actively in the modeling process. Input strokes can be automatically aligned with image edges, accelerating the process of tracing an object feature. The image can also be used as texture and shape information to enhance the 3d model. Taken together, this thesis advances the state of SBIM in several important ways. The main contributions are the stroke classification, feature-based subdivision surface creation, image-assisted interface, and region-based annotations for shape deformation. To demon­strate the combined power of these components, several results and applications are presented, along with a user study that argues for the usability of the overall approach.

Optimal Adaptive Prediction Intervals for Electricity Load Forecasting in Distribution Systems via Reinforcement Learning

description: Prediction intervals offer an effective tool for quantifying the uncertainty of loads in distribution systems. The traditional central PIs cannot adapt well to skewed distributions, and their offline training fashion is vulnerable to unforeseen changes in future load patterns. Therefore, we propose an optimal PI estimation approach, which is online and adaptive to different data distributions by adaptively determining symmetric or asymmetric probability proportion pairs for quantiles. It relies on the online learning ability of reinforcement learning to integrate the two online tasks, i.e., the adaptive selection of probability proportion pairs and quantile predictions, both of which are modeled by neural networks. As such, the quality of quantiles-formed PI can guide the selection process of optimal probability proportion pairs, which forms a closed loop to improve the quality of PIs. Furthermore, to improve the learning efficiency of quantile forecasts, a prioritized experience replay strategy is proposed for online quantile regression processes. Case studies on both load and net load demonstrate that the proposed method can better adapt to data distribution compared with online central PIs method. Compared with offline-trained methods, it obtains PIs with better quality and is more robust against concept drift.

description: The pervasive presence spatial and size structure in biological populations challenges fundamental assumptions at the heart of continuum models of population dynamics based on mean densities (local or global) only. Individual-based models (IBM's) were introduced over the last decade in an attempt to overcome this limitation by following explicitly each individual in the population. Although the IBM approach has been quite insightful, the capability to follow each individual usually comes at the expense of analytical tractability, which limits the generality of the statements that can be made. For the specific case of spatial structure in populations of sessile (and identical) organisms, space-time point processes with local regulation seem to cover the middle ground between analytical tractability and a higher degree of biological realism. Continuum approximations of these stochastic processes distill their fundamental properties, but they often result in infinite hierarchies of moment equations. We use the principle of constrained maximum entropy to derive a closure relationship for one such hierarchy truncated at second order using normalization and the product densities of first and second orders as constraints. The resulting `maxent' closure is similar to the Kirkwood superposition approximation, but it is complemented with previously unknown correction terms that depend on on the area for which third order correlations are irreducible. This region also serves as a validation check, since it can only be found if the assumptions of the closure are met. Comparisons between simulations of the point process, alternative heuristic closures, and the maxent closure show significant improvements in the ability of the maxent closure to predict equilibrium values for mildly aggregated spatial patterns.

description: Linear spectral mixture models can be standardized by using endmembers that span the global mixing space. By combining the benefits of location-specific mixture models with standardized spectral indices, standardized mixture models offer consistency, simplicity, inclusivity and applicability. We construct a globally representative mixing space using a spectrally diverse collection of 100 Landsat ETM+ (Thematic Mapper and Enhanced Thematic Mapper +) subscenes. Global composites of 100,000,000 Landsat spectra, constructed from both exoatmospheric reflectance and atmospherically corrected surface reflectance, represent the spectral diversity of a wide range of terrestrial environments. Principal Component (PC) Analysis of the global composite shows that 99% of the spectral variance can be represented in a 3-dimensional mixing space of the low order PCs. Within this 3D space 98% of spectra are contained within a tetrahedral hull bounded by a continuous plane of substrates, and well-defined apexes corresponding to vegetation and dark endmembers. Suites of individual substrate, vegetation and dark endmember spectra are used to derive mean endmembers and to quantify the effects of endmember variability on fractions estimated from a standardized Substrate, Vegetation, and Dark (SVD) linear mixture model. Maximum endmember variability introduces less than 0.05 difference in S, V, and D fractions for most SVD models constructed from individual pixel endmember spectra giving less than 0.05 model misfit for more than 97% of pixels in the global composite. The mean SVD endmembers define a standard global mixture model for Landsat spectra. These SVD endmembers can be used to model mixed reflectance spectra from other sensors with similar spectral responses to Landsat ETM+. Comparisons of endmember fractions estimated from coincident acquisitions of Landsat TM and ETM + and WorldView-2 imagery show strong linear scaling for vegetation and dark fractions. Substrate fractions do not scale as linearly for the urban validation sites because the Landsat substrate endmember does not accurately represent the impervious surfaces imaged by WorldView-2. Comparisons of Landsat and WorldView-2 unmixed with the same Visible-Near Infrared (VNIR) endmembers derived from the global Landsat endmembers are also strongly correlated but with reduced bias. This linear scaling suggests that the Landsat global endmembers may provide a basis for standardized mixture models for WorldView-2 and other broadband sensors with spectral response similar to Landsat TM and ETM+. Comparisons of vegetation fractions with vegetation indices for the global composite show strong linear correspondence for Tasseled Cap Greenness and Enhanced Vegetation Index, with some degree of saturation at high fractions for the Soil Adjusted Vegetation Index and a wide range of responses for the Normalized Difference Vegetation Index.

description: We introduce a method to test if a given velocity definition corresponds to an actual physical flow, when the pulse propagation in dispersive medium is considered. i) We calculate the mean arrival time between two positions in space, using the Fourier expansion in real-ωspace. ii) We calculate the mean spatial displacement between two points in time, using the Fourier expansion in real-k space. We compare the velocities calculated in the two approaches. If the velocity definition truly corresponds to an actual flow, the two velocities must be the same. However, we show that the two velocities differ significantly (4%) in the region of superluminal propagation even for the successful definition introduced by Peatross et al. [Phys. Rev. Lett. 84, 2370 (2000)].

description: With the shrinking of technology nodes and the use of parallel processor clusters in hostile and critical environments, such as space, run-time faults caused by radiation are a serious cross-cutting concern, also impacting architectural design. This paper introduces an architectural approach to run-time configurable soft-error tolerance at the core level, augmenting a six-core open-source RISC-V cluster with a novel On-Demand Redundancy Grouping (ODRG) scheme. ODRG allows the cluster to operate either as two fault-tolerant cores, or six individual cores for high-performance, with limited overhead to switch between these modes during run-time. The ODRG unit adds less than 11% of a core's area for a three-core group, or a total of 1% of the cluster area, and shows negligible timing increase, which compares favorably to a commercial state-of-the-art implementation, and is 2.5$\times$ faster in fault recovery re-synchronization. Furthermore, when redundancy is not necessary, the ODRG approach allows the redundant cores to be used for independent computation, allowing up to 2.96$\times$ increase in performance for selected applications.

description: Stroke, the interruption in blood flow to the brain, initiates a neurotoxic cascade that leads to cell death. The aim of this thesis was to determine the role of Panx 1 channels in the neurotoxic cascade induced by ischemia in the rat hippocampus. Two approaches were taken: (1) the link between Panxl opening and MPT activation was investigated by monitoring dye efflux using live cell fluorescence microscopy, (2) the involvement of Panxl in cell death was determined by Western blot analysis of cleaved cytoskeletal protein, a-fodrin. Ischemia induced opening of the MPT was prevented by blocking calcium influx through Panxl channels. Panxl opening during ischemia also induced calpain proteolysis. This cleavage was prevented when either Panxl or the MPT were blocked. Therefore, opening of Panxl during ischemia activates the MPT and calpain proteases via calcium influx, indicating that Panxl channels induce neuronal death through mitochondria dysfunction and degradation of the cytoskeleton.

description: Background: The Ministry of Health in Malawi is implementing a pragmatic and innovative approach for the management of all HIV-infected pregnant women, termed Option B+, which consists of providing life-long antiretroviral treatment, regardless of their CD4 count or clinical stage. Our objective was to determine if Option B+ represents a cost-effective option.
Methods: A decision model simulates the disease progression of a cohort of HIV-infected pregnant women receiving prophylaxis and antiretroviral therapy, and estimates the number of paediatric infections averted and maternal life years gained over a ten-year time horizon. We assess the cost-effectiveness from the Ministry of Health perspective while taking into account the practical realities of implementing ART services in Malawi. Results: If implemented as recommended by the World Health Organization, options A, B and B+ are equivalent in preventing new infant infections, yielding cost effectiveness ratios between US$ 37 and US$ 69 per disability adjusted life year averted in children. However, when the three options are compared to the current practice, the provision of antiretroviral therapy to all mothers (Option B+) not only prevents infant infections, but also improves the ten-year survival in mothers more than four-fold. This translates into saving more than 250,000 maternal life years, as compared to mothers receiving only Option A or B, with savings of 153,000 and 172,000 life years respectively. Option B+ also yields favourable incremental cost effectiveness ratios (ICER) of US$ 455 per life year gained over the current practice. Conclusion: In Malawi, Option B+ represents a favorable policy option from a cost-effectiveness perspective to prevent future infant infections, save mothers’ lives and reduce orphanhood. Although Option B+ would require more financial resources initially, it would save societal resources in the long-term and represents a strategic option to simplify and integrate HIV services into maternal, newborn and child health programmes.

description: Magnitude is a numerical invariant of compact metric spaces, originally inspired by category theory and now known to be related to myriad other geometric quantities. Generalizing earlier results in $\ell_1^n$ and Euclidean space, we prove an upper bound for the magnitude of a convex body in a hypermetric normed space in terms of its Holmes-Thompson intrinsic volumes. As applications of this bound, we give short new proofs of Mahler's conjecture in the case of a zonoid, and Sudakov's minoration inequality.

description: C-theory provides a unified framework to study metric, metric-affine and more general theories of gravity. In the vacuum weak-field limit of these theories, the parameterized post-Newtonian (PPN) parameters $β$ and $γ$ can differ from their general relativistic values. However, there are several classes of models featuring long-distance modifications of gravity but nevertheless passing the Solar system tests. Here it is shown how to compute the PPN parameters in C-theories and also in nonminimally coupled curvature theories, correcting previous results in the literature for the latter.

Estimation of the geometric measure of entanglement with Wehrl Moments through Artificial Neural Networks

description: In recent years, artificial neural networks (ANNs) have become an increasingly popular tool for studying problems in quantum theory, and in particular entanglement theory. In this work, we analyse to what extent ANNs can accurately predict the geometric measure of entanglement of symmetric multiqubit states using only a limited number of Wehrl moments (moments of the Husimi function of the state) as input, which represents partial information about the state. We consider both pure and mixed quantum states. We compare the results we obtain by training ANNs with the informed use of convergence acceleration methods. We find that even some of the most powerful convergence acceleration algorithms do not compete with ANNs when given the same input data, provided that enough data is available to train these ANNs. We also provide an experimental protocol for measuring Wehrl moments, which is state-independent. More generally, this work opens up perspectives for the estimation of entanglement measures and other SU(2)-invariant quantities, such as the Wehrl entropy, in a way that is more accessible in experiments than by means of full state tomography.

description: The problem of organizing information for multidocument summarization so that the generated summary is coherent has received relatively little attention. While sentence ordering for single document summarization can be determined from the ordering of sentences in the input article, this is not the case for multidocument summarization where summary sentences may be drawn from different input articles. In this paper, we propose a methodology for studying the properties of ordering information in the news genre and describe experiments done on a corpus of multiple acceptable orderings we developed for the task. Based on these experiments, we implemented a strategy for ordering information that combines constraints from chronological order of events and topical relatedness. Evaluation of our augmented algorithm shows a significant improvement of the ordering over two baseline strategies.

description: For a proper, geodesic, Gromov hyperbolic metric space X, a discrete subgroup of isometries Γwhose limit set is uniformly perfect, and a disjoint collection of horoballs {H_j}, we show that the set of limit points badly approximable by {H_j} is absolutely winning in the limit set. As an application, we deduce that for a geometrically finite Kleinian group acting on H^{n+1}, the limit points badly approximable by parabolics is absolutely winning, generalizing previous results of Dani and McMullen. As a consequence of winning, we show that the set of badly approximable limit points has dimension equal to the critical exponent of the group. Since this set can alternatively be described as the limit points representing bounded geodesics in the quotient H^{n+1}/Γ, we recapture a result originally due to Bishop and Jones.
