description: Cylindrically reduced Einstein gravity can be regarded as an $SL(2,R)/SO(2)$ sigma model coupled to 2D dilaton gravity. By using the corresponding 2D diffeomorphism algebra of constraints and the asymptotic behaviour of the Ernst equation we show that the theory can be mapped by a canonical transformation into a set of free fields with a Minkowskian target space. We briefly discuss the quantization in terms of these free-field variables, which is considerably simpler than in the other approaches.

description: It is well recognized that the role of zoning is essential in planning for wind energy. Wind energy zoning is not regulated at the federal level. The responsibility of regulating wind energy projects falls on states and cities, except on federal lands or when special laws apply (e.g. Federal Aviation Regulations). As more local governments explore their roles and responsibilities in climate change adaptation and mitigation, policies and zoning regulations related to distributed wind energy systems are constantly being added or updated. There is little consistency throughout the United States in regards to wind energy zoning. Local or state (or sometimes both) authorities can regulate wind energy facilities (Redburn, 2017). New York State's law, Chapter 388 of the Laws of 2011 that enacted Article 10 of the Public Service Law defines a major electric generating facility as facilities of 25 megawatts or more. The installation and modification of such facilities require environmental and public health impact analyses, a utility security plan, and advising interested parties and members of the public (Chapter 388 of the Laws of 2011). Facilities with capacity under 25 megawatts are not subjected to the requirement. This study does research on small-scale distributed wind energy conversion systems, as defined by the New York City Zoning Resolution (2018). Concerns related to visual impacts, sound, safety, and threats to wildlife are raised whenever there are wind energy facilities siting projects. The goal of the study is to analyze the regulations on which the amendment relies, identify if and how the zoning text addresses public concerns, challenges it encountered, and potential improvements.

description: The observation of the non-Keplerian behavior of propeller structures in Saturn's outer A ring (Tiscareno et al. 2010, Seiler et al. 2017, Spahn et al. 2018) raises the question, how the propeller responds to the wandering of the central embedded moonlet. Here, we study numerically how the induced propeller is changing for a librating moonlet. It turns out, that the libration of the moonlet induces an asymmetry in the structural imprint of the propeller, where the asymmetry is depending on the moonlet's libration period and amplitude. Further, we study the dependence of the asymmetry on the libration period and amplitude for a moonlet with 400 m Hill radius, which is located in the outer A ring. In this way, we are able to apply our findings to the largest found propeller structures -- such as Blériot -- which are expected to be of similar size. For Blériot, we can conclude that, supposed the moonlet is librating with the largest observed period of 11.1 years and an azimuthal amplitude of about 1845 km (Seiler et al. 2017, Spahn et al. 2018), a small assymmetry should be measurable but depends on the moonlet's libration phase at the observation time. The excess motions of the other giant propellers -- such as Santos Dumont and Earhart -- have similar amplitudes as Blériot and thus might allow the observation of larger asymmetries due to their smaller azimuthal extent. This would permit to scan the whole gap structure for asymmetries. Although the librational model of the moonlet is a simplification, our results are a first step towards the development of a consistent model for the description of the formation of asymmetric propellers caused by a freely moving moonlet.

description: We present a method for time series analysis of both, scalar and nonscalar time-delay systems. If the dynamics of the system investigated is governed by a time-delay induced instability, the method allows to determine the delay time. In a second step, the time-delay differential equation can be recovered from the time series. The method is a generalization of our recently proposed method suitable for time series analysis of {\it scalar} time-delay systems. The dynamics is not required to be settled on its attractor, which also makes transient motion accessible to the analysis. If the motion actually takes place on a chaotic attractor, the applicability of the method does not depend on the dimensionality of the chaotic attractor - one main advantage over all time series analysis methods known until now. For demonstration, we analyze time series, which are obtained with the help of the numerical integration of a two-dimensional time-delay differential equation. After having determined the delay time, we recover the nonscalar time-delay differential equation from the time series, in agreement with the 'original' time-delay equation. Finally, possible applications of our analysis method in such different fields as medicine, hydrodynamics, laser physics, and chemistry are discussed.

description: In this paper we calculate the entropy of a thin spherical shell that contracts reversibly from infinity down to its event horizon. We find that, for a broad class of equations of state, the entropy of a non-extremal shell is one-quarter of its area in the black hole limit. The considerations in this paper suggest the following operational definition for the entropy of a black hole: $S_{BH}$ is the equilibrium thermodynamic entropy that would be stored in the material which gathers to form the black hole, if all of this material were compressed into a thin layer near its gravitational radius. Since the entropy for a given mass and area is maximized for thermal equilibrium we expect that this is the maximum entropy that could be stored in the material before it crosses the horizon. In the case of an extremal black hole the shell model does not assign an unambiguous value to the entropy.

description: LINEAR 1169665 is a RR Lyrae of sub-type c discovered by the asteroid survey LINEAR. The robotic telescope TAROT at Calern Observatory has observed it between the years 2006 and 2015. The present study of TAROT data as well as those from the surveys ASAS-SN (2012-2019) and LINEAR (2002-2008) shows that this star presents a period modulation with a period of 1800.1 days (4.9 years) but with no significant variation of magnitude at maximum. This phenomenon is similar to the one found in KEPLER data for the RRc KIC 2831097 (Sodor et al., 2017) which was suspected to be the result of a light time effect in a double stellar system. The large modulation period and the lack of amplitude modulation exclude it to be attributed to a Blazhko effect. But alternatively to the light time effect this phenomenon might be due to a new modulation phenomenon with long period affecting at least RRc stars.

Zoning for Exchange: Creative-Industrial Incubators in North Brooklyn and the Formalization of Innovation

Zoning
Cultural industries

description: Despite its stated purpose, land use zoning has struggled to respond and proactively shape the dynamic processes that create vibrant and diverse urban spaces. Emerging from nuisance protection and deliberation, land use zoning has historically aimed to create a more efficient regulatory framework. In removing the conflict between noxious industrial uses and residential development, it reduced the threat to economic growth and improved overall public welfare. However, with recent improvements in industrial environmental regulations, and a shift in manufacturing processes, the industrial-residential conflict needs to be re-evaluated. The North Brooklyn creative-industrial sector is a vibrant and essential part of New York City's economy, building cultural capital through agglomeration and exchange. However, it requires particular spatial organization and social interactions to thrive. A broad perspective on these issues is gained though interviews with city planners, manufacturing policy analysts, industrial real estate developers, and small-scale manufacturers. A close look at the land use changes that followed the 2005 Williamsburg-Greenpoint rezoning as a Special Mixed Use District shows the weaknesses of zoning as a mixed-use facilitator. If city planners intend to address the contemporary conflicts between residential, manufacturing, and other commercial land uses without hindering the positive exchanges that arise from their interactions, regulatory and support mechanisms outside of the current zoning framework need to be applied. Planners need to remove restrictions on interactions, while strengthening the networks where they occur. They need to level the playing field through financial incentives, institutional support, and infrastructure development. Most importantly, planners need to actively promote an increase in the types of spaces, primarily multi-story loft buildings, where these interactions thrive.

description: The time evolution of an initially uncorrelated system is governed by a completely positive (CP) map. More generally, the system may contain initial (quantum) correlations with an environment, in which case the system evolves according to a not-completely positive (NCP) map. It is an interesting question what the relative measure is for these two types of maps within the set of positive maps. After indicating the scope of the full problem of computing the true volume for generic maps acting on a qubit, we study the case of Pauli channels in an abstract space whose elements represent an equivalence class of maps that are identical up to a non-Pauli unitary. In this space, we show that the volume of NCP maps is twice that of CP maps.

description: This thesis analyzes the mortars used in the construction of Guastavino tile vault assemblies through an in-depth study of St. Paul’s Chapel and observations at five other Guastavino projects. Limited research has been published that addresses the mortars used in Guastavino vaults, but the available literature indicates that only gypsum mortar and Portland cement mortar were used in their construction. Furthermore, literature establishes that vaults were assembled by installing the first layer of tiles with gypsum mortar, while the above tile layers were set in Portland cement mortar. Preservation professionals often encounter discrepancies between this assembly described in literature and the assemblies and mortars observed during restoration projects. To address these discrepancies, this thesis performed a material study at St. Paul’s Chapel, identifying the mortars and their assembly through archival review, physical observation, and cursory petrographic analysis of select samples. It was determined that at least four different types of mortars, including gypsum mortar, gypsum-lime mortar, natural cement mortar, and portland cement mortar were used in the construction of St. Paul’s Chapel. Furthermore, it was discovered that the used mortar types varied by the form and finish of different vaults at St. Paul’s Chapel. Similarly, in the supporting case studies, mortars other than gypsum mortar and portland cement mortar were identified, again varying based on the particularities of the assembly of each vault. The variety of these materials and assemblies illustrate the oversimplification of the description of Guastavino vault assemblies in published literature. This thesis therefore provides schematic section drawings of the studied vaults that identify the types of mortar used and their locations within the vault assembly. While only a fraction of the projects of the Guastavino Company were analyzed in this thesis, the chosen case studies clearly demonstrate that the company used mortars other than gypsum mortars and Portland cement mortars. Furthermore, this thesis establishes that the type of mortar used in a Guastavino project was intricately linked to the assembly method, and that both mortar and assembly varied based on the specific parameters of particular projects.

description: We present a method for the identification of continuous, spatiotemporal dynamics from experimental data. We use a model in the form of a partial differential equation and formulate an optimization problem for its estimation from data. The solution is found as a multivariate nonlinear regression problem using the ACE-algorithm. The procedure is successfully applied to data, obtained by simulation of the Swift-Hohenberg equation. There are no restrictions on the dimensionality of the investigated system, allowing for the analysis of high-dimensional chaotic as well as transient dynamics. The demands on the experimental data are discussed as well as the sensitivity of the method towards noise.
Inextendible Schwarzschild black hole with a single exterior: How thermal is the Hawking radiation?

description: Several approaches to Hawking radiation on Schwarzschild spacetime rely in some way or another on the fact that the Kruskal manifold has two causally disconnected exterior regions. We investigate the Hawking(-Unruh) effect for a real scalar field on the $\RPthree$ geon: an inextendible, globally hyperbolic, space and time orientable eternal black hole spacetime that is locally isometric to Kruskal but contains only one exterior region. The Hartle-Hawking-like vacuum~$\hhvacgeon$, which can be characterized alternatively by the positive frequency properties along the horizons or by the complex analytic properties of the Feynman propagator, turns out to contain exterior region Boulware modes in correlated pairs, and any operator in the exterior that only couples to one member of each correlated Boulware pair has thermal expectation values in the usual Hawking temperature. Generic operators in the exterior do not have this special form; however, we use a Bogoliubov transformation, a particle detector analysis, and a particle emission-absorption analysis that invokes the analytic properties of the Feynman propagator, to argue that $\hhvacgeon$ appears as a thermal bath with the standard Hawking temperature to any exterior observer at asymptotically early and late Schwarzschild times. A~(naive) saddle-point estimate for the path-integral-approach partition function yields for the geon only half of the Bekenstein-Hawking entropy of a Schwarzschild black hole with the same ADM mass: possible implications of this result for the validity of path-integral methods or for the statistical interpretation of black-hole entropy are discussed. Analogous results hold for a Rindler observer in a flat spacetime whose global properties mimic those of the geon.

These identities have the same product side as the (first) Andrews--Gordon identity for modulus 2ab\pm 1, but an altogether different sum side, based on the representation of (a/b-1)^{\pm 1} as a continued fraction. Our proof, which relies on the Burge transform, first establishes a binary tree of polynomial identities. Each identity in this Burge tree settles a special case of Bressoud's generalized Borwein conjecture.

description: Collisions with windows are one of the main causes of human-induced bird deaths (Klem et al. 2014). Indeed, University of British Columbia (UBC) Sustainability estimates that more than 10,000 birds are killed on the UBC campus annually. These collisions occur as a result of birds attempting to fly through transparent glass, or mistaking reflections in windows as a part of their environment (Martin 2011). UBC shares its campus with various species of wildlife, including birds. The campus is situated on the Pacific Flyway, the route that migratory birds use during their bi-annual migrations from Alaska to Central and South America (City of Vancouver 2015). Birds provide important ecosystem services, such as pest management, nutrient cycling, and promotion of feelings of well-being in nearby humans. UBC Sustainability has therefore identified the need to promote a campus that is inclusive to non-human organisms. With this in mind, various buildings on UBC’s campus have added art to their windows to prevent bird collisions. However, launching such an initiative requires several significant considerations. The purpose of this project is to identify successful strategies for creating community-engaged window art that reduces bird collisions, and to provide recommendations for how other buildings on campus can similarly be retrofitted. Hummingbird Daycare, a childcare centre located on the south-west side of UBC campus, has been identified by UBC’s SEEDS (Social Ecological Economic Development Studies) Sustainability Program as a hotspot for bird collisions. Therefore, we have tailored recommendations for this particular case. Disclaimer: “UBC SEEDS Sustainability Program provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

description: This dissertation is an ethnography centered around two bands based in Guangzhou and their relationships with one of China’s largest record companies. Bridging ethnomusicology, popular music studies, cultural geography, media studies, vocal anthropology, and the anthropology of infrastructure, it examines emergent forms of musical creativity and modes of circulation as they relate to shifts in concepts of self, space, publics, and state instigated by China’s political and economic reforms. Chapter One discusses a long history of state-sponsored cartographic musical anthologies, as well as Confucian and Maoist ways of understanding the relationships between place, person, and music. These discussions provide a context for understanding contemporary musical cosmopolitanisms that both build upon and disrupt these histories; they also provoke a rethinking of ethnomusicological and related linguistic theorizations about music, place, and subjectivity. Through biographies of seven musicians working in present-day Guangzhou, Chapter Two outlines a concept of “musical subjectivity” that looks to the intersection of personal histories, national histories, and creativity as a means of exploring the role of individual agency and expressive culture in broader cultural shifts. Chapter Three focuses on the intertwining of actual corporeal mobilities and vicarious musical mobilities, and explores relationships between circulations of global popular musics, emergent forms of musical creativity, and an evolving geography of contemporary China. Chapter Four extends these concerns to a discussion of media systems in China, and outlines an approach to “sonic infrastructures” that puts sound studies in dialogue with the anthropology of infrastructure in order to understand how evolving modes of musical circulation and the listening practices associated with them are connected to broader economic, political, and cultural spatialities. Finally, Chapter Five examines the intersecting aesthetic and political implications of popular music sung in local languages (fangyan) by focusing on contemporary forms of articulation between music, language, listening, and place. Taken together, these chapters explore musical cosmopolitanisms as knowledge-making processes that are reconfiguring notions of self, state, publics, and space in contemporary China.

description: Transport signatures of exchange gap opening because of magnetic proximity effect (MPE) are reported for bilayer structures of Bi2Se3 thin films on yttrium iron garnet (YIG) and thulium iron garnet (TmIG) of perpendicular magnetic anisotropy (PMA). Pronounced negative magnetoresistance (MR) was detected, and attributed to an emergent weak localization (WL) effect superimposing on a weak antilocalization (WAL). Thickness-dependent study shows that the WL originates from the time-reversal-symmetry breaking of topological surface states by interfacial exchange coupling. The weight of WL declined when the interfacial magnetization was aligned toward the in-plane direction, which is understood as the effect of tuning the exchange gap size by varying the perpendicular magnetization component. Importantly, magnetotransport study revealed anomalous Hall effect (AHE) of square loops and anisotropic magnetoresistance (AMR) characteristic, typifying a ferromagnetic conductor in Bi2Se3/TmIG, and the presence of an interfacial ferromagnetism driven by MPE. Coexistence of MPE-induced ferromagnetism and the finite exchange gap provides an opportunity of realizing zero magnetic-field dissipation-less transport in topological insulator/ferromagnetic insulator heterostructures.

Static Axially Symmetric Einstein-Yang-Mills-Dilaton Solutions: II.Black Hole Solutions

description: We discuss the new class of static axially symmetric black hole solutions obtained recently in Einstein-Yang-Mills and Einstein-Yang-Mills-dilaton theory. These black hole solutions are asymptotically flat and they possess a regular event horizon. The event horizon is almost spherically symmetric with a slight elongation along the symmetry axis. The energy density of the matter fields is angle-dependent at the horizon. The static axially symmetric black hole solutions satisfy a simple relation between mass, dilaton charge, entropy and temperature. The black hole solutions are characterized by two integers, the winding number $n$ and the node number $k$ of the purely magnetic gauge field. With increasing node number the magnetically neutral black hole solutions form sequences tending to limiting solutions with magnetic charge $n$, corresponding to Einstein-Maxwell-dilaton black hole solutions for finite dilaton coupling constant and to Reissner-Nordstrøm black hole solutions for vanishing dilaton coupling constant.

description: The past few years have been marked by an increased use of sensor technologies, abundant availability of mobile devices, and growing popularity of wearables, which enable the direct integration of their data as part of rich client applications. Despite the potential and added value that such aggregate applications bring, the implementations are usually custom solutions for particular use cases and do not support easy integration of further devices. To this end, the vision of the Web of Things (WoT) is to leverage Web standards in order to interconnect all types of devices and real-world objects, and thus to make them a part of the World Wide Web (WWW) and provide overall interoperability. In this context we introduce Smart Web Services (SmartWS) that not only provide remote access to resources and functionalities, by relying on standard communication protocols, but also encapsulate `intelligence'. Smartness features can include, for instance, context-based adaptation, cognition, inference and rules that implement autonomous decision logic in order to realize services that automatically perform tasks on behalf of the users, without requiring their explicit involvement. In this paper, we present the key characteristics of SmartWS, and introduce a reference implementation framework. Furthermore, we describe a specific use case for implementing SmartWS in the medical domain and specify a maturity model for determining the quality and usability of SmartWS.

description: We construct a class of linear partial differential equations describing general perturbations of non-rotating black holes in 3D Cartesian coordinates. In contrast to the usual approach, a single equation treats all radiative $\ell -m$ modes simultaneously, allowing the study of wave perturbations of black holes with arbitrary 3D structure, as would be present when studying the full set of nonlinear Einstein equations describing a perturbed black hole. This class of equations forms an excellent testbed to explore the computational issues of simulating black spacetimes using a three dimensional adaptive mesh refinement code. Using this code, we present results from the first fully resolved 3D solution of the equations describing perturbed black holes. We discuss both fixed and adaptive mesh refinement, refinement criteria, and the computational savings provided by adaptive techniques in 3D for such model problems of distorted black holes.

Universality of Probability Distributions Among Two-Dimensional Turbulent Flows
Creators: name: Schorghofer, Norbert
Publisher: name: arXiv
Year: 1999
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: We study statistical properties of two-dimensional turbulent flows. Three systems are considered: the Navier-Stokes equation, surface quasi-geostrophic flow, and a model equation for thermal convection in the Earth's mantle. Direct numerical simulations are used to determine 1-point fluctuation properties. Comparative study shows universality of probability density functions (PDFs) across different types of flow. Especially for the derivatives of the ``advected'' quantity, the shapes of the PDFs are the same for the three flows, once normalized by the average size of fluctuations. Theoretical models for the shape of PDFs are briefly discussed.

Lefschetz pencils and divisors in moduli space

description: We study Lefschetz pencils on symplectic four-manifolds via the associated spheres in the moduli spaces of curves, and in particular their intersections with certain natural divisors. An invariant defined from such intersection numbers can distinguish manifolds with torsion first Chern class. We prove that pencils of large degree always give spheres which behave `homologically' like rational curves; contrastingly, we give the first constructive example of a symplectic non-holomorphic Lefschetz pencil. We also prove that only finitely many values of signature or Euler characteristic are realised by manifolds admitting Lefschetz pencils of genus two curves.

description: We consider the Schwinger's method of angular momentum addition using the SU(2) algebra with both a fermionic and a bosonic oscillator. We show that the total spin states obtained are: one boson singlet state and an arbitrary number of spin-1/2 states, the later ones are energy degenerate. It means that we have in this case supersymmetric quantum mechanics and also the addition of angular momentum for massless particles. We review too the cases of two bosonic and fermionic oscillators.

description: ALICE Overwatch is a project started in late 2015 to provide augmented online monitoring and data quality assurance utilizing time-stamped QA histograms produced by the ALICE High Level Trigger. The system receives the data via ZeroMQ, stores it for later review, enriches it with detector specific functionality, and visualizes it via a web application. These provided capabilities are complementary to the existing Data Quality Monitoring system. In addition to basic visualization, additional processing options are accessible to the user, including requests for data within a particular time range or reprocessing of a particular run with different processing parameters. For example, the first ten minutes of a particular run could be investigated for a transient hot trigger channel. Due to similarities between the Overwatch architecture and that which will be used for Quality Control (QC) in LHC Run 3 and beyond, Overwatch will also be utilized to develop and test various QC components during LHC Run 2. Some of the areas of QC development include a new trending and alarm framework. We report on the project's design, development, and status.

description: The black hole transient H1743-322 exhibited several outbursts with temporal and spectral variability since its discovery in 1977. These outbursts occur at a quasi-regular recurrence period of around $0.5-2$ years, since its rediscovery in March 2003. We investigate accretion flow dynamics around the Low Mass X-ray Binary H1743-322 during its 2004 outburst using the RXTE/PCA archival data. We use Two Component Advective Flow (TCAF) solution to analyse the spectral data. From the fits with TCAF solution, we obtain day to day variation of physical accretion rates of Keplerian and sub-Keplerian components, size of the Compton cloud and its other properties. Analysis of the spectral properties of the 2004 outburst by keeping fitted normalization to be in a narrow range and its timing properties in terms of the presence and absence of QPOs, enable us to constrain the mass of the black hole in a range of $10.31 M_{\odot} - 14.07 M_{\odot}$ which is consistent with other estimates reported in the literature.

description: Photon counting detection is a promising approach toward effectively reducing the radiation dose in x-ray computed tomography (CT). Full CT reconstruction from a fraction of the detected photons required by scintillation-based detectors has been demonstrated. Current efforts in photon-counting CT have focused mainly on reconstruction techniques. In medical and industrial x-ray computed tomography (CT) applications, truncated projection from the region-of-interest (ROI) is another effective way of dose reduction, as information from the ROI is usually sufficient for diagnostic purpose. Projection truncation poses an ill-conditioned inverse problem, which can be improved by including projections from the exterior region. However, this trade-off between the interior reconstruction quality and the additional exterior measurement (extra dose) has not been studied. In this manuscript, we explore the number of detected x-ray photons as a new dimension for measurement engineering. Specifically, we design a flexible, photon-efficient measurement strategy for ROI reconstruction by incorporating the photon statistics at extremely low flux level (~10 photons per pixel). The optimized photon-allocation strategy shows 10 ~ 15-fold lower ROI reconstruction error than truncated projections, and 2-fold lower than whole-volume CT scan. Our analysis in few-photon interior tomography could serve as a new framework for dose-efficient, task-specific x-ray image acquisition design.
