description: Evidence-based Medicine (EBM) is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patient. Billions of dollars are spent annually on the conduct of randomized clinical trials (RCT), one type of experiments widely regarded as yielding the most valuable evidence. Yet, the number of studies is growing exponentially, and most experiment results are published only as text-based articles in the medical journal, causing difficulties for both practitioners and researchers in searching, synthesizing, and ultimately, translating the best available evidence to the patient care. To address the problem, I aim to develop a unified information extraction framework for medical evidence, and build novel computational approaches based upon it to make evidence from research more accessible in Evidence-based Medicine. In this dissertation, I (i) present a unified conceptual model and coordinated workflow for evidence representation, (ii) develop open-source NLP tools for supporting EBM tasks (evidence extraction, retrieval, and synthesis), (iii) develop a medical evidence base to cater various information needs, and (iv) present a new machine reading comprehension model for answering clinical questions.

description: Hamilton variational principle for special type of statistical ensemble of deterministic dynamical systems is derived. Thie form of variational principle allows one to describe the statistical ensemble in terms of wave functions and provides a basis for a description of statistical ensemble of stochastic systems. It is shown that sometimes such a statistical description of stochastic particle motion appears to coincide with the quantum description in terms of Schroedinger equation.

description: The benefits of reclamation under current Kentucky regulations unambiguously exceed reclamation costs; the incremental benefits of reclamation. under the currently introduced Federal Bill, are positive and under certain assumptions exceed costs. Even assuming application of best available reclamation technologies in the study region, surface coal mining generates residual social costs.

description: We construct a $C^r$ transformation of the interval (or the torus) which is topologically mixing but has no invariant measure of maximal entropy. Whereas the assumption of $C^{\infty}$ ensures existence of maximal measures for an interval map, it shows we cannot weaken the smoothness assumption. We also compute the local entropy of the example.

A technology-aided social marketing approach for domestic hot water consumption reduction in a multi-unit residential building
Creators: name: Iniesta, Edgar David Sotelo
Publisher: name: The University of British Columbia
Year: 2014

description: The purpose of this project was to examine the effectiveness of a behavioral change pilot program aimed to reduce hot water consumption in the Clement's Green residential building located at UBC Vancouver campus. The project was supported by an online communication tool provided by BuiltSpace Technologies and hot water sub-metering provided by Enerpro Systems. During this project, a new method for providing consumption information to building occupants was pilot tested as a means to stimulate a reduction in hot water consumption. This strategy was underpinned with a behavioral change program following the steps suggested by Doug McKenzie-Mohr [1]. The pilot was launched with a group of nine volunteers who live in the building. Hot water consumption data was analyzed before and after the deployment of the strategy. There is not enough information to observe statistical evidence of a reduction in hot water consumption due to high variability in the after-deployment dataset. An extension of the after-deployment stage is suggested to overcome this lack of evidence. Nevertheless, participants agreed that the improvement in availability of consumption information from this pilot was useful to them in regards to understanding their hot water usage and ultimately, this could lead to a reduction in consumption.

description: As organizations increasingly use cloud services to host their IT infrastructure, there is a need to share data among these cloud hosted services and systems. A majority of IT organizations have workloads spread across different cloud service providers, growing their multi-cloud environments. When an organization grows their multi-cloud environment, the threat vectors and vulnerabilities for their cloud systems and services grow as well. The increase in the number of attack vectors creates a challenge of how to prioritize mitigations and countermeasures to best defend a multi-cloud environment against attacks. Utilizing multiple industry standard risk analysis tools, we conducted an analysis of multi-cloud threat vectors enabling calculation and prioritization for the identified mitigations and countermeasures. The prioritizations from the analysis showed that authentication and architecture are the highest risk areas of threat vectors. Armed with this data, IT managers are able to more appropriately budget cybersecurity expenditure to implement the most impactful mitigations and countermeasures.

description: The Casimir interaction and torque are related phenomena originating from the exchange of electromagnetic excitations between objects. While the Casimir force exists between any types of objects, the materials or geometrical anisotropy drives the emergence of the Casimir torque. Here both phenomena are studied theoretically between dielectric films with immersed parallel single wall carbon nanotubes in the dilute limit with their chirality and collective electronic and optical response properties taken into account. It is found that the Casimir interaction is dominated by thermal fluctuations at sub-micron separations, while the torque is primarily determined by quantum mechanical effects. This peculiar quantum vs. thermal separation is attributed to the strong influence of reduced dimensionality and inherent anisotropy of the materials. Our study suggests that nanostructured anisotropic materials can serve as novel platforms to uncover new functionalities in ubiquitous Casimir phenomena.

description: We derive the Feynman rules for the graviton in the presence of a flat Robertson-Walker background and give explicit expressions for the propagator in the physically interesting cases of inflation, radiation domination, and matter domination. The aforementioned background is generated by a scalar field source which should be taken to be dynamical. As an elementary application, we compute the corrections to the Newtonian gravitational force in the present matter dominated era and conclude -- as expected -- that they are negligible except for the largest scales.

Offset errors in probabilistic inversion of small-loop frequency-domain electromagnetic data: a synthetic study on their influence on magnetic susceptibility estimation

description: Small-loop frequency-domain electromagnetic (FDEM) devices measure a secondary magnetic field caused by the application of a stronger primary magnetic field. Both the in-phase and quadrature component of the secondary field commonly suffer from systematic measurement errors, which would result in a non-zero response in free space. The in-phase response is typically strongly correlated to subsurface magnetic susceptibility. Considering common applications on weakly to moderately susceptible grounds, the in-phase component of the secondary field is usually weaker than the quadrature component, making it relatively more prone to systematic errors. Incorporating coil-specific offset parameters in a probabilistic inversion framework, we show how systematic errors in FDEM measurements can be estimated jointly with electrical conductivity and magnetic susceptibility. Including FDEM measurements from more than one height, the offset estimate becomes closer to the true offset, allowing an improved inversion result for the subsurface magnetic susceptibility.

description: We study how to use the surface states in a Bi$_{2}$Se$_{3}$ topological insulator ultra-thin film that are affected by finite size effects for the purpose of quantum computing. We demonstrate that: (i) surface states under the finite size effect can effectively form a two-level system where their energy levels lie in between the bulk energy gap and a logic qubit can be constructed, (ii) the qubit can be initialized and manipulated using electric pulses of simple forms, (iii) two-qubit entanglement is achieved through a $\sqrt{\text{SWAP}}$ operation when the two qubits are in a parallel setup, and (iv) alternatively, a Floquet state can be exploited to construct a qubit and two Floquet qubits can be entangled through a Controlled-NOT operation. The Floquet qubit offers robustness to background noise since there is always an oscillating electric field applied, and the single qubit operations are controlled by amplitude modulation of the oscillating field, which is convenient experimentally.

Exclusive diffractive J/psi and Psi(2S) production in dipole model using a holographic AdS/QCD light front wavefunction with longitudinal confinement

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We use an anti-de Sitter/Quantum Chromodynamics (AdS/QCD) based holographic light-front wavefunction (LFWF) for vector meson, in conjunction with the dipole model to investigate the cross-sections data for the diffractive and exclusive J/psi and Psi(2S) production. We confront the experimental data using a new explicit form of the holographic LFWF, where the longitudinal confinement dynamics in light-front Schrodinger equation is captured by 't Hooft equation of (1+1)-dim, in large Nc approximation, in addition to the transverse confinement dynamics governed by the confining mass scale parameter, kappa in vector mesons. We obtain the LFWF parameters from fitting to the exclusive J/psi electro production data from electron-proton collision at HERA collider for m_c = 1.27 GeV. Our results suggest that the dipole model together with holographic meson LFWFs with longitudinal confinement is able to give a successful description for differential scattering cross-section for exclusive J/psi electro production for H1 and ZEUS data. We also predict the rapidity distributions of differential scattering cross-section and total photo production of J/psi and Psi(2S) states in proton-proton ultra-peripheral collisions(UPCs) at center of mass energy sqrt s = 7, 13 TeV. Using the minimum set of parameters, our predictions for the UPCs are in good agreement with the recent experimental observations of UPCs at ALICE and LHCb Collaborations.

This anisotropic spectra can assume both scale-invariant and non scale-invariant form. The implications for the evolution of the acoustic turbulence with non-isotropic pumping are discussed. The main result of the article is that the spectra of acoustic turbulence tend to become more isotropic.

description: With the two most profound conceptual revolutions of XXth century physics, quantum mechanics and relativity, which have culminated into relativistic spacetime geometry and quantum gauge field theory as the principles for gravity and the three other known fundamental interactions, the physicist of the XXIst century has inherited an unfinished symphony: the unification of the quantum and the continuum. As an invitation to tomorrow's quantum geometers who must design the new rulers by which to size up the Universe at those scales where the smallest meets the largest, these lectures review the basic principles of today's conceptual framework, and highlight by way of simple examples the interplay that presently exists between the quantum world of particle interactions and the classical world of geometry and topology.

Starting from the operator formalism and then combining techniques of path integration in polar coordinates and in spaces with constraints, the propagator and its path integral representation are derived. "Quantum correction" in the Lagrangian appears naturally and no a priori assumption is made about connectivity of the configuration space.

description: Object grasping is an important ability required for various robot tasks. In particular, tasks that require precise force adjustments during operation, such as grasping an unknown object or using a grasped tool, are difficult for humans to program in advance. Recently, AI-based algorithms that can imitate human force skills have been actively explored as a solution. In particular, bilateral control-based imitation learning achieves human-level motion speeds with environmental adaptability, only requiring human demonstration and without programming. However, owing to hardware limitations, its grasping performance remains limited, and tasks that involves grasping various objects are yet to be achieved. Here, we developed a cross-structure hand to grasp various objects. We experimentally demonstrated that the integration of bilateral control-based imitation learning and the cross-structure hand is effective for grasping various objects and harnessing tools.

description: The possibility of Fast Radio Burst (FRB) emission being suppressed at low frequencies, resulting in a cutoff of the average rest-frame spectrum, has been raised as an explanation for the lack of detections at meter wavelengths. We examine propagation effects that could cause this suppression, and find that a low-frequency spectral cutoff may be generic regardless of the specific FRB emission mechanism. We then illustrate the effects of a low-frequency spectral cutoff on the statistics of FRBs, given a cosmological source population. The observed FRB rate peaks at a specific frequency under a variety of assumptions. Observations at lower frequencies are more sensitive to high-redshift events than observations above the maximal-rate frequency, and therefore result in more sharply broken fluence distributions. Our results suggest that the absence of low-frequency FRBs, and the differences between the Parkes and the Australian Square Kilometre Array (ASKAP) FRB samples, can be fully explained by suppressed low-frequency FRB emission.

Absolute spacetime: the twentieth century ether

Publisher: name: arXiv
Year: 1998
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: All gauge theories need ``something fixed'' even as ``something changes.'' Underlying the implementation of these ideas all major physical theories make indispensable use of an elaborately designed spacetime model as the ``something fixed,'' i.e., absolute. This model must provide at least the following sequence of structures: point set, topological space, smooth manifold, geometric manifold, base for various bundles. The ``fine structure'' of spacetime inherent in this sequence is of course empirically unobservable directly, certainly when quantum mechanics is taken into account. This issue is at the basis of the difficulties in quantizing general relativity and has been approached in many different ways. Here we review an approach taking into account the non-Boolean properties of quantum logic when forming a spacetime model. Finally, we recall how the fundamental gauge of diffeomorphisms (the issue of general covariance vs coordinate conditions) raised deep conceptual problems for Einstein in his early development of general relativity. This is clearly illustrated in the notorious ``hole'' argument. This scenario, which does not seem to be widely known to practicing relativists, is nevertheless still interesting in terms of its impact for fundamental gauge issues.

Tracing Tarbiya: Women, Education, and Childrearing in Lebanon and Egypt, 1860-1939

description: “Tracing Tarbiya” is a feminist conceptual history of education and upbringing as they were articulated by intellectuals writing in Arabic between the last decades of the Ottoman Empire and the outbreak of the second World War. It focuses on women writers raised in the educational crucible of Beirut and Mount Lebanon who moved to Cairo and Alexandria around 1900 to become theorists of tarbiya, an old Arabic word for cultivation and upbringing that came in the nineteenth century to refer to new structures of formal schooling, new pedagogies, and the feminized labor of childrearing, moral cultivation, and subject formation in the home. Through the work of these writers and others, the concept of tarbiya moved across gender, geography, and sect to enable new political imaginaries: upbringing became the way to shape men and women fit for representative politics, to produce an Arab world capable of facing rising European power, and to refashion Muslim, Christian, and European intellectual traditions for a new age. "Tracing Tarbiya" makes three main arguments. First, while scholars have highlighted the ongoing importance of affective and embodied practices of subject cultivation within the Islamic tradition, this story shows how new pedagogies based around affect and embodiment captivated both Christians and Muslims between 1860 and 1939. Second, this work traces the ongoing power of discourses about motherhood and childrearing to show how writers in Beirut, Cairo, and Alexandria came to identify tarbiya as the foundation of successful reform, making women, children, and the family into a primary site for political argument and action. Finally, “Tracing Tarbiya” puts gendered discourses about upbringing at the center of the history of representative governance in the Arab world, proposing that a non-Western political concept might help us to better understand the disjuncture between the promises of representative democracy and its actual outcomes in Egypt, Lebanon, and beyond. By adopting conceptual history methods, it shows how debates about tarbiya identified women's capabilities as childraisers as a way to bridge two contradictions central to actualizing liberal political ideals: first, the contradiction between legal equality and human difference, and second, the tension between the promises of mass politics and the desires of reformist elites.

description: Die vorliegende Arbeit gibt einen Abriss über die Grundlagen des Brandenburgisch-Preußischen Fürsorgeerziehungssystems am Beispiel des Brandenburgischen Mädchenfürsorgeheims in Prenzlau, das in den Jahren 1902 bis 1935 bestand. Basierend auf historischer und erziehungswissenschaftlicher Forschung werden die Lebens- und Arbeitsverhältnisse junger Mädchen und Frauen und Erzieherinnen im Fürsorgesystem epochenübergreifend aufgezeigt. Vor diesem Hintergrund erfolgte (in der Forschung erstmalig) die Rekonstruktion des geografischen und sozialen Raums des Brandenburgischen Mädchenfürsorgeheims mit seinen Spezifika als Heim für ‚verwahrloste‘, schulentlassene Mädchen, also Mädchen und junge Frauen im Alter von 14 bis 21 bzw. 19 Jahren. Dabei wird die Anstalt als eigenes System betrachtet, das von der Gesellschaft durch herrschende Diskurse, Normsetzungen und ökonomische Rahmenbedingungen beeinflusst war, gleichzeitig aber ein eigenes Regelsystem in Form einer festen Tagesstruktur, Disziplinierungsmaßnahmen und religiösen Ritualen ausbildete und den historischen Akteur*innen sehr eigene Handlungsspielräume und Grenzen aufzeigte. Grundlage der Arbeit sind ungedruckte und gedruckte Quellen wie die Verwaltungsberichte des Provinzialausschusses, die „Statistiken über die Fürsorgeerziehung Minderjähriger und über die Zwangserziehung Jugendlicher“ des Preußischen Innenministeriums, zahlreiches Kartenmaterial und Gebäudezeichnungen, Verwaltungsunterlagen sowie vier persönliche Briefe von Zöglingen und Angehörigen. Die verfügbaren statistischen Angaben zu den Mädchen des Heims sind in Form von Diagrammen zusammengefasst, aufgearbeitet und der Arbeit angehängt worden.
Drain water heat recovery : a review of performance, economics, practical issues and applications
Creators: name: Frankowski, Chris
Publisher: name: The University of British Columbia
Year: 2014

description: This project evaluates the economics of Drain Water Heat Recovery (DWHR), more specifically the performance of a horizontal DWHR device manufactured by EcoDrain, the A1000. The device was tested in a rig that mimics a typical real world installation. The temperature increase and flow rate of fresh water passing through the device was recorded to determine the energy saved while showering. Both the transient and steady state performance of the device was determined. By combining the testing results with a dataset of Canadian household sizes, showering habits, and energy costs, a recommendation is made for the conditions under which the installation of an EcoDrain would be economically advantageous. The testing simulates an installation where the fresh water being preheated supplies only the associated fixture, which would be the easiest installation for an existing building. Testing showed an average temperature increase of 12.2°C with a flow rate of 3.87 L/min of fresh water passing through the DWHR device, which corresponds to a heat transfer rate (power savings) of 3.29 kW, and a total of 0.43 kWh saved per shower. The average Canadian household has a size of 2.59 people, with each person showering once a day for 8.5 minutes each. Energy costs vary significantly around the country, but the average electricity rate is 9.41¢/kWh and 7.13 $/GJ. For the average household, the NPV of DWHR is -$203.68 for homes with electric water heaters and -$464.88 for homes with natural gas water heaters. DWHR is much more economical for households with electric hot water heaters as their energy costs are much higher. A household of 4 or more people with an electric hot water heater would benefit from installing a DWHR device such as the EcoDrain. Locations with natural gas heaters would benefit from DWHR if there are more than 14 users a day, or if natural gas prices return to more historic levels.

description: This paper proposes a multiagent based bi-level operation framework for the low-carbon demand management in distribution networks considering the carbon emission allowance on the demand side. In the upper level, the aggregate load agents optimize the control signals for various types of loads to maximize the profits; in the lower level, the distribution network operator makes optimal dispatching decisions to minimize the operational costs and calculates the distribution locational marginal price and carbon intensity. The distributed flexible load agent has only incomplete information of the distribution network and cooperates with other agents using networked communication. Finally, the problem is formulated into a networked multi-agent constrained Markov decision process, which is solved using a safe reinforcement learning algorithm called consensus multi-agent constrained policy optimization considering the carbon emission allowance for each agent. Case studies with the IEEE 33-bus and 123-bus distribution network systems demonstrate the effectiveness of the proposed approach, in terms of satisfying the carbon emission constraint on demand side, ensuring the safe operation of the distribution network and preserving privacy of both sides.

The Schwinger Model and the Physical Projector: a Nonperturbative Quantization without Gauge Fixing

description: Based on the physical projector approach, a nonpertubative quantization of the massless Schwinger model is considered which does not require any gauge fixing. The spectrum of physical states, readily identified following a diagonalization of the operator algebra, is that of a massive pseudoscalar field, namely the electric field having acquired a mass proportional to the gauge coupling constant. The physical spectrum need not be identified with confined bound fermion-antifermion pairs, an interpretation which one is otherwise led to given whatever gauge fixing procedure but which is not void of gauge fixing artefacts.

Boundary sensitive Lindbladians and relaxation dynamics

description: It is well known that non-Hermitian systems can be extremely sensitive to boundary conditions owing to non-Hermitian skin effect (NHSE). Analogously, we investigate two boundary-sensitive $U(1)$ symmetric Lindbladians: one carries current in the steady state, and the other does not. The numerical results indicate significant change of the Liouvillian spectrum, eigenmodes and relaxation time for both Lindbladians when the boundary conditions are altered. This phenomenon is found to be triggered by the Liouvillian skin effect (LSE), specifically the localization of eigenmodes, which stems from the NHSE of the non-Hermitian effective Hamiltonian. In addition, these two Lindbladians manifest different LSE, ultimately resulting in distinct relaxation behaviors.

description: We calculate new evolutionary models of rotating primordial very massive stars, with initial mass from $100\,M_{\odot}$ to $200\,M_{\odot}$, for two values of the initial metallicity ${Z=0}$ and ${Z=0.0002}$. For the first time in this mass range, we consider stellar rotation and pulsation-driven mass loss, along with radiative winds. The models evolve from the zero-age main sequence, until the onset of pair instability. We discuss the main properties of the models during their evolution and then focus on the final fate and the possible progenitors of jet-driven events. All tracks that undergo pulsational-pair instability produce successful gamma-ray bursts (GRB) in the collapsar framework, while those that collapse directly to black holes (BH) produce jet-driven supernova events. In these latter cases, the expected black hole mass changes due to the jet propagation inside the progenitor, resulting in different models that should produce BH within the pair-instability black-hole mass gap. Successful GRBs predicted here from zero-metallicity and very metal-poor progenitors may be bright enough to be detected even up to redshift ${\sim20}$ using current telescopes such as the Swift-BAT X-ray detector and the JWST.

Asymptotic pairs in positive-entropy systems

description: We show that in a topological dynamical system $(X,T)$ of positive entropy there exist proper (positively) asymptotic pairs, that is, pairs $(x,y)$ such that $x\not= y$ and $\lim_{n\to +\infty} d(T^n x,T^n y)=0$. More precisely we consider a $T$-ergodic measure $μ$ of positive entropy and prove that the set of points that belong to a proper asymptotic pair is of measure $1$. When $T$ is invertible, the stable classes (i.e., the equivalence classes for the asymptotic equivalence) are not stable under $T^{-1}$: for $μ$-almost every $x$ there are uncountably many $y$ that are asymptotic with $x$ and such that $(x,y)$ is a Li-Yorke pair with respect to $T^{-1}$. We also show that asymptotic pairs are dense in the set of topological entropy pairs.

description: This project investigates forms of investment in residential property that began to emerge in the lead up to the 2008 financial crisis, which have since morphed and firmly taken hold. Focused on Philadelphia, PA, the analysis traces the new geographies of real estate purchases made specifically by investors who do not intend to live in the homes they are buying. The project uses a mixed methods approach to uncover how houses purchased as investment vehicles between 2000-2018 have been concentrated spatially, then com- pares these patterns with the geography of houses that have been purchased as homes. The research shows that investors have consistently focused their efforts on Philadelphia neighborhoods with a higher proportion of residents of color and lower incomes. Over the nineteen-year span of this study it is clear that investor activity not only plays a large role in the housing bubble in Philadelphia, but is also continuing to grow as a percentage of overall purchases, and is expanding into new areas of the city. Principally, the project reveals that the geographies of purchases by investors and owner-occupants are largely distinct –inves- tor ownership is fueling a separate housing geography and is not merely a part of the overall housing market. To take up these complexities I draw together literature on the political economic implications of financialization in housing with research on neighborhood-level impacts of house 'flipping' as well as the new single-family rental (SFR) asset class. Through this research, the project considers the implications of these patterns in a context where, facing years of disinvestment, Philadelphia community development organizations and city government have largely been eager for the influx of capital brought through speculative investment in housing even as they simultaneously deal with related waves of displacement and evictions.

description: In this review we try to give a pedagogical introduction to the recent progress in the resolution of old problems of black hole thermodynamics within superstring theory. We start with a brief description of classical black hole dynamics. Then, follow with the consideration of general properties of supersymmetric black holes. We conclude with the review of the statistical explanation of the black hole entropy and string theory description of the black hole evaporation.

Geometric Quantization on the Super-Disc

description: In this article we discuss the geometric quantization on a certain type of infinite dimensional super-disc. Such systems are quite natural when we analyze coupled bosons and fermions. The large-N limit of a system like that corresponds to a certain super-homogeneous space. First, we define an example of a super-homogeneous manifold: a super-disc. We show that it has a natural symplectic form, it can be used to introduce classical dynamics once a Hamiltonian is chosen. Existence of moment maps provide a Poisson realization of the underlying symmetry super-group. These are the natural operators to quantize via methods of geometric quantization, and we show that this can be done.
