description: Solving jigsaw puzzles is a classic problem in computer vision with various applications. Over the past decades, many useful approaches have been introduced. Most existing works use edge-wise similarity measures for assembling puzzles with square pieces of the same size, and recent work innovates to use the loop constraint to improve efficiency and accuracy. We observe that most existing techniques cannot be easily extended to puzzles with rectangular pieces of arbitrary sizes, and no existing loop constraints can be used to model such challenging scenarios. In this paper, we propose a new corner-wise matching approach, modelled using the MatchLift framework to solve square puzzles with cycle consistency. We further show one exciting example illustrating how puzzles with rectangular pieces of arbitrary sizes would be solved by our technique.

description: The black hole of the widely used ordinary 2d--dilaton model (DBH) deviates from the Schwarzschild black hole (SBH) of General Relativity in one important feature: Whereas non-null extremals or geodesics show the expected incompleteness this turns out {\it not to be the case for the null extremals}. After a simple analysis in Kruskal coordinates for singularities with power behavior of this -- apparently till now overlooked -- property we discuss the global structure of a large family of generalized dilaton theories which does not only contain the DBH and SBH but also other proposed dilaton theories as special cases. For large ranges of the parameters such theories are found to be free from this defect and exhibit global SBH behavior.

Biological treatment of tailings solution at the Nickel Plate Mine
Creators: name: Given, Barry

Publisher: name: The University of British Columbia
Year: 2009

description: During the closure of the Homestake Nickel Plate Mine, located in south central British Columbia, there was a need to remove cyanide and other contaminants from water stored in the tailings impoundment prior to releasing the water to a nearby stream. Several water management and treatment alternatives were considered including land application, biological treatment, breakpoint chlorination, hydrogen peroxide, and the lnco SO2/Air process which was already in use at the mine. After extensive evaluations, the decision was made to use a combined aerobic and anaerobic biological treatment system for removal of residual cyanide, thiocyanate, ammonia, and nitrate, coupled with a High Density Sludge (HDS) process for removal of residual metals. The aerobic biological process utilized expertise and experience associated with the original biological treatment process still in use at the Homestake Gold Mine located in Lead, South Dakota, USA. The anaerobic biological process utilized experience developed through bench scale and pilot plant evaluations at the Nickel Plate mine. This paper will discuss the development and operation of the combined full scale biological treatment process. The discussion will include the decant or reclaim water characteristics, the basic process chemistry, the original bench and pilot plant evaluations, design considerations, effluent limitations, and an evaluation of the first year of full scale operation.

description: Radiographers need to know a broad range of knowledge about X-ray radiography, which can be specific to each part of the body. Due to the harmfulness of the ionising radiation used, teaching and training using real patients is not ethical. Students have limited access to real X-ray rooms and anatomic phantoms during their studies. Books, and now web apps, containing a set of static pictures are then often used to illustrate clinical cases. In this study, we have built an Interactive X-ray Projectional Simulator using a deformation algorithm with a real-time X-ray image simulator. Users can load various anatomic models and the tool enables virtual model positioning in order to set a specific position and see the corresponding X-ray image. It allows teachers to simulate any particular X-ray projection in a lecturing environment without using real patients and avoiding any kind of radiation risk. This tool also allows the students to reproduce the important parameters of a real X-ray machine in a safe environment. We have performed a face and content validation in which our tool proves to be realistic (72% of the participants agreed that the simulations are visually realistic), useful (67%) and suitable (78%) for teaching X-ray radiography.

description: To investigate the effect of sea buckthorn puree consumption on reducing blood lipid and other risk factors of CVD. A total of 111 patients with hypercholesteromia who were treated with 90 ml sea buckthorn puree or placebo for 90 days were enrolled in this trial. Physical examination and analysis of lipid markers, hsCRP concentrations and cell adhesion protein concentrations with fasting blood samples were performed at 0-day, 45-day and 90-day after treatment. We found that the sea buckthorn puree did not affect the levels of serum total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) and triglyceride (TG). However, the level of HDL-C was decreased by sea buckthorn puree in a short period (first 6 weeks), which was increased in the last 6 weeks (p < 0.05). Compared with placebo, diastolic blood pressure (DBP) was decreased after taking sea buckthorn puree (p > 0.05). There was moderately decreased in hsCRP concentration in sea buckthorn group. Nevertheless, there was no correlation between changes in ICAM-1 and VCAM-1 concentration. In conclusion, long term consumption of sea buckthorn puree has anti-inflammatory and anti-hypertensive effects on hypercholesterolemia in hypercholesterolemic patients. However, it did not translate into an effect on the concentration of lipid markers in the circulation.
Quasiequilibrium sequences of synchronized and irrotational binary neutron stars in general relativity. III. Identical and different mass stars with gamma=2

description: We present the first computations of quasiequilibrium binary neutron stars with different mass components in general relativity, within the Isenberg-Wilson-Mathews approximation. We consider both cases of synchronized rotation and irrotational motion. A polytropic equation of state is used with the adiabatic index gamma=2. The computations have been performed for the following combinations of stars: (M/R)_{star 1} vs. (M/R)_{star 2} = 0.12 vs. (0.12, 0.13, 0.14), 0.14 vs. (0.14, 0.15, 0.16), 0.16 vs. (0.16, 0.17, 0.18), and 0.18 vs. 0.18, where (M/R) denotes the compactness parameter of infinitely separated stars of the same baryon number. It is found that for identical mass binary systems there is no turning point of the binding energy (ADM mass) before the end point of the sequence (mass shedding point) in the irrotational case, while there is one before the end point of the sequence (contact point) in the synchronized case. On the other hand, in the different mass case, the sequence ends by the tidal disruption of the less massive star (mass shedding point). It is then more difficult to find a turning point in the ADM mass. Furthermore, we find that the deformation of each star depends mainly on the orbital separation and the mass ratio and very weakly on its compactness. On the other side, the decrease of the central energy density depends on the compactness of the star and not on that of the companion.

However, the model and its implications are easily misunderstood. Thus, we present a guide to help understand and avoid misinterpreting it. Focusing on the five assumptions, underlying the model, we define figures of merit to quantify how close real solar cells approach each of these assumptions.
A Mesh Correspondence Approach for Efficient Animation Transfer

description: Animating a novel character not only needs a lot of effort and time but also requires the intervention of an experienced user. Moreover, the traditional animation pipeline for a set of characters can be a tedious and cumbersome process which often needs to be repeated several times to correct artifacts. We propose a user-friendly, semi-automated efficient method which is realized in two phases: (i) mesh correspondence, and (ii) skeleton and skinning transfer. We have developed a software tool for realizing the entire process without the need of third party software. We have improved the efficiency of the entire animation transfer process. To substantiate this, we provide a comparative performance evaluation with previous competent approaches.

description: Recognising Human-object interactions (HOIs) in videos is a challenge task especially when a human can interact with multiple objects. This paper attempts to solve the problem of HOIs by proposing a hierarchical framework that analyzes human-object interactions from a video sequence. The framework consists of LSTMs that firstly capture both human motion and temporal object information independently, followed by fusing these information through a bilinear layer to aggregate human-object features, which are then fed to a global deep LSTM to learn high-level information of HOIs. The proposed approach applies an attention mechanism to LSTMs in order to focus on important parts of human and object temporal information.

description: Capital Markets Union (CMU) is a plan towards a single market for capital in the EU. While the plan is not limited to the euro area, some of its stated objectives are aimed at supporting EMU, especially by financial stability through private risk-sharing. The present Article seeks to specify and clarify these EMU objectives. It points out their expressions in official documents, discusses their role in creating legislative momentum for CMU and its individual initiatives, and observes them in the legislative process and content of selected initiatives. The research results include an explanation of the significance of EMU objectives as arguments in debates and decision-making concerning CMU as well as an assessment of their justificatory force.

description: The disintegration of quasiparticle in a quantum dot due to the electron interaction is considered. It was predicted recently that above the energy $\eps^{*} = Δ(g/\ln g)^{1/2}$ each one particle peak in the spectrum is split into many components ($Δ$ and $g$ are the one particle level spacing and conductance). We show that the observed value of $\eps^{*}$ should depend on the experimental resolution $δ\eps$. In the broad region of variation of $δ\eps$ the $\ln g$ should be replaced by $\ln(Δ/ gδ\eps)$. We also give the arguments against the delocalization transition in the Fock space. Most likely the number of satellite peaks grows continuously with energy, being $\sim 1$ at $\eps \sim \eps^{*}$, but remains finite at $\eps > \eps^{*}$. The predicted logarithmic distribution of inter-peak spacings may be used for experimental confirmation of the below-Golden-Rule decay.

We also comment on various aspects of the continuum theory.

description: Sussex Archaeological Collections, 143, 47-69
description: Report on a programme of archaeological investigations undertaken in 2001 in advance of car park development in the North-West Zone of Gatwick Airport. The investigations culminated in the excavation of a partially enclosed Late Bronze Age settlement lying on the edge of the River Mole floodplain. Pollen, plant and insect remains indicated that the settlement occupied an area of previously cleared forest and woodland. An open landscape of grassland floodplain with scattered clumps of trees provided browsing and grazing for domestic animals. It is suggested that tillage occurred on the higher ground beyond the floodplain. The settlement developed and the landscape was cleared for pasture. The floodplain became drier, possibly because of modification and management of the watercourses and the increasing intensity in land-use. The excavation has demonstrated the archaeological and palaeo-environmental potential of the Mole Valley as it cuts through the Weald. Includes separately authored contributions on

Polyacenes and diffuse interstellar bands

description: The identification of the carriers of the diffuse interstellar bands (DIBs) remains to be established, with the exception of five bands attributed to C60+, although it is generally agreed that DIB carriers should be large carbon-based molecules (with ~10-100 atoms) in the gas phase, such as polycyclic aromatic hydrocarbons (PAHs), long carbon chains or fullerenes. More specific possible carriers among PAHs are investigated, namely elongated molecules, which could explain a correlation between the DIB wavelength and the apparent UV resilience of their carriers. We address the case of polyacenes, C4N+2-H2N+4, with N~10-18 fused rectilinear aligned hexagons. Polyacenes are attractive DIB carrier candidates because their high symmetry and large linear size allow them to form regular series of bands in the visible range with strengths larger than most other PAHs, as confirmed by recent laboratory results up to undecacene (C46H26). Those with very strong bands in the DIB spectral domain are just at the limit of stability against UV photodissociation. They are part of the prominent PAH family of interstellar carbon compounds, meaning that only ~10-5 of the total PAH abundance is enough to account for a medium-strength DIB. After summarizing the current knowledge about the properties of polyacenes and recent laboratory results, the likelihood that they might meet the criteria for being carriers of some DIBs is addressed by reviewing the following properties: wavelength and strength of their series of visible bands; interstellar stability and abundances, charge state and hydrogenation; and DIB rotation profiles. No definite inconsistency has been identified that precludes polyacenes from being the carriers of some DIBs with medium or weak strength, including the so-called C2 DIBs. But additional experimental data about long acenes and their visible bands are needed to make robust conclusions

description: A literary thesis on paternal power and presence in classical French theatre, this essay analyzes the following concepts: the father's role separate from the father himself, the mobility of the paternal/the ability of the paternal to exercise its power through characters other than the father, and the omnipresent, omnipotent characteristics of the father's influence on other characters (namely those in his family). A main inspiration for this analysis is the work of Sigmund Freud, specifically his theory on the augmentation of paternal power after the father's death. This thesis focuses primarily on Le Cid by Pierre Corneille, Le Malade imaginaire by Molière, and Jean Racine's Phèdre.

description: The slow-rotation approximation of Hartle is developed to a setting where a charged rotating fluid is present. The linearized Einstein-Maxwell equations are solved on the background of the Reissner-Nordstrom space-time in the exterior electrovacuum region. The theory is put to action for the charged generalization of the Wahlquist solution found by Garcia. The Garcia solution is transformed to coordinates suitable for the matching and expanded in powers of the angular velocity. The two domains are then matched along the zero pressure surface using the Darmois-Israel procedure. We prove a theorem to the effect that the exterior region is asymptotically flat if and only if the parameter C_{2}, characterizing the magnitude of an external magnetic field, vanishes. We obtain the form of the constant C_{2} for the Garcia solution. We conjecture that the Garcia metric cannot be matched to an asymptotically flat exterior electrovacuum region even to first order in the angular velocity. This conjecture is supported by a high precision numerical analysis.

description: We introduce an evolutionary algorithm called recombinator-$k$-means for optimizing the highly non-convex kmeans problem. Its defining feature is that its crossover step involves all the members of the current generation, stochastically recombining them with a repurposed variant of the $k$-means++ seeding algorithm. The recombination also uses a reweighting mechanism that realizes a progressively sharper stochastic selection policy and ensures that the population eventually coalesces into a single solution. We compare this scheme with state-of-the-art alternative, a more standard genetic algorithm with deterministic pairwise-nearest-neighbor crossover and an elitist selection policy, of which we also provide an augmented and efficient implementation. Extensive tests on large and challenging datasets (both synthetic and real-word) show that for fixed population sizes recombinator-$k$-means is generally superior in terms of the optimization objective, at the cost of a more expensive crossover step. When adjusting the population sizes of the two algorithms to match their running times, we find that for short times the (augmented) pairwise-nearest-neighbor method is always superior, while at longer times recombinator-$k$-means will match it and, on the most difficult examples, take over. We conclude that the reweighted whole-population recombination is more costly, but generally better at escaping local minima. Moreover, it is algorithmically simpler and more general (it could be applied even to $k$-medians or $k$-medoids, for example). Our implementations are publicly available at \href{https://github.com/carlobaldassi/RecombinatorKMeans.jl}{https://github.com/carlobaldassi/RecombinatorKMeans.jl}.

Laïcité in Contemporary France: Analyzing the Implementation and Retention of Religious Programming on Publically Supported Television
Creators: Turner, Elizabeth
Publisher: name: Columbia University
Year: 2017
Subjects: Religion on television
Public television
Church and state
Religious broadcasting
Secularism

description: This research seeks to understand the rationale behind the implementation and retention of religious programming on publicly supported television in France. Centering on questions of laïcité in the post-Vatican II era of the early 1950s, this thesis will attempt to delineate the ways in which the separation between church and state is understood and enacted within the context of a secular nation. A consideration of the substantial influence imposed upon the State by the historical dominance of the Catholic Church in France will further provide the background for understanding the environment and political influences that led to the establishment of religious programming. Looking specifically at the program Le Jour du Seigneur, broadcasted on the public service station France 2, this research will examine the decisions made towards the program’s conception and further follow its trajectory into the contemporary era. The particular content of the program, as well as understanding the demographics of its viewership and its reception over time, offers insight into the specific climate that fostered the establishment of Le Jour du Seigneur. Further, a comparison with other similar religious broadcasts, on both public and privatized stations, will illustrate the motives behind continued retention, particularly amidst the backdrop of increasing secularization and declining religious worship. The ultimate objective of this research is to put the question of religious programming on public service stations in conversation with the governing principles of laïcité to determine how pluralism and republican values continue to incite conflict in the secular nation of France.

description: In the context of face recognition systems, liveness test is a binary classification task aiming at distinguishing between input images that come from real people's faces and input images that come from photos or videos of those faces, and presented to the system's camera by an attacker. In this paper, we train the state-of-the-art, general purpose deep neural network ResNet for liveness testing, and measure the effect on its performance of adversarial attacks based on the manipulation of the saturation component of the imposter images. Our findings suggest that higher saturation values in the imposter images lead to a decrease in the network's performance. Next, we study the relationship between the proposed adversarial attacks and corresponding direct presentation attacks. Initial results on a small dataset of processed images which are then printed on paper or displayed on an LCD or a mobile phone screen, show that higher saturation values lead to higher values in the network's loss function, indicating that these colour manipulation techniques can indeed be converted into enhanced presentation attacks.

Treatment of runoff containing suspended solids resulting from mine construction activities using sedimentation ponds
Creators: name: Clark, J. P.
Publisher: name: The University of British Columbia
Year: 2009

description: Sedimentation control during mine construction is attracting increased interest and regulation. The significance of this for the proponents of new mines and regulators suggests the need for more detailed planning and testing prior to construction for activities that could potentially generate sediment. The topic of designing the appropriate sedimentation pond size to remove nonfilterable residue (TSS) from contaminated runoff is discussed. Designing the appropriate pond size has been based on a "traditional" approach and methodology in BC which has assumed that the surface area of the pond should be large enough to settle out approximately 10 fi and larger particles for the maximum ten-year, 24-hour rainfall event. This approach is not related to the particle size distribution of the soils to be disturbed nor the soil erosion rates, and therefore cannot predict the pond discharge quality. If the "traditional" design methodology results in regulatory compliance, it is merely a fortuitous outcome of the design process, and a reflection of the absence of "abundant fines" in the soils. Modification to this "traditional" approach is suggested so that we predict the optimum surface area of the sedimentation pond, the need to use settling aids and whether the pond discharge will meet statutory requirements. The appropriate time to perform these predictions and testing is recommended; during the review stage (under the Environmental Assessment Act in BC). Although this approach is not novel, it will hopefully enable the more blatantly problematic soils to be identified and receive more focus prior to actual construction (e.g. preparations to select and obtain approval for the use of effective and non-toxic flocculants well ahead of the construction taking place, and placing more emphasis on planning sedimentation control strategies).

description: In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After summarizing this work, we introduce the Fourier sRGB color space. It is defined in terms of Fourier coefficients but designed to behave similar to sRGB. Textures stored in Fourier sRGB support efficient spectral rendering but can be compressed with techniques designed for sRGB textures. Compression errors are similar to sRGB.

Leadership Action-logics and Application of Lean in an Organizational Health Care Setting

Subjects: Adult education

description: The research aim is to contribute to scholarly inquiry on best practices for institutional leaders in health care organizations who are leading improvement work. The goal is to investigate how a specific sustainable continuous improvement methodology—lean management (LM)—is experienced by leaders charged with implementing it to improve health care locally. Adult development can be understood as stage-based theory of growth across the human life-span and has been successfully applied to enhance understanding of how adults approach uncertainty and complexity, yet it has not been applied to understand how institutional leaders go about understanding, implementing, and leading improvement work via LM. The primary research focus is how improvement leaders in an academic health care organization describe the implementation experience of LM and how, if at all, LM varies as a function of improvement leaders’ stage of development, as represented by their assessed action-logic. This study represents the first step in an exploratory agenda to integrate adult developmental theory with LM application in health care by first understanding how LM’s application in hospital settings may vary with individual project leaders’ stages of development and how their descriptions of LM implementations during key implementation points within an advanced and internally offered Black Belt training program may match the intent of LM as a systemic, principle-based approach to health care change within an organization implementing it as organization-wide strategy for improvement.
Leadership Behavioral Complexity as an Antecedent to Scaling Social Impact and Financial Performance

description: This study sought to understand whether leaders of nonprofit social enterprises could influence their organization's ability to pursue social and financial goals through developing necessary organizational capabilities. A mediation model where organizational capabilities (SCALERS, Structure and System) served as potential mediators of the proposed relationship between leadership behavioral complexity and perceptions of scaling social impact and financial stability was tested. Leaders with greater behavioral complexity were argued to have a wider portfolio of behaviors to develop organizational capabilities, which would in turn allow organizations to reach contradictory, social and financial goals. Eighty-three executives in the social sector (primarily nonprofit) completed an online survey. A sub-sample of 12 executives participated in follow-up qualitative interviews. Ordinary least square regression was used to test the study hypotheses. Results showed that organizational capabilities predicted perceptions of scaling social impact and financial stability. However, there was no support for organizational capabilities as a mediator between leadership behavioral complexity and the study outcome variables. Post-hoc, exploratory analyses revealed a subtler, unanticipated mediated relationship where specific capabilities (i.e., lobbying, earnings generation, replication and stimulating market forces) mediated the impact of organizational structure and system on perceptions of scaling social impact and financial stability. Moreover, the study shed new light on previously held assumptions about the relationship between social and financial goals in nonprofit social enterprises. Implications for theory, future research, and practice are discussed.
