description: We construct uniform and point-wise asymptotic confidence sets for the single edge in an otherwise smooth image function which are based on rotated differences of two one-sided kernel estimators. Using methods from M-estimation, we show consistency of the estimators of location, slope and height of the edge function and develop a uniform linearization of the contrast process. The uniform confidence bands then rely on a Gaussian approximation of the score process together with anti-concentration results for suprema of Gaussian processes, while point-wise bands are based on asymptotic normality. The finite-sample performance of the point-wise proposed methods is investigated in a simulation study. An illustration to real-world image processing is also given.

description: The energy and time variables of the elementary classical dynamical systems are described geometrically, as canonically conjugate coordinates of an extended phase-space. It is shown that the Galilei action of the inertial equivalence group on this space is canonical, but not Hamiltonian equivariant. Although it has no effect at classical level, the lack of equivariance makes the Galilei action inconsistent with the canonical quantization. A Hamiltonian equivariant action can be obtained by assuming that the inertial parameter in the extended phase-space is quasi-isotropic. This condition leads naturally to the Lorentz transformations between moving frames as a particular case of symplectic transformations. The limit speed appears as a constant factor relating the two additional canonical coordinates to the energy and time. Its value is identified with the speed of light by using the relationship between the electromagnetic potentials and the symplectic form of the extended phase-space.

description: This contribution aims to publicize the efforts made in the identification of gas hydrates in the Uruguayan continental shelf, analyze the most outstanding aspects related to its energy potential, as well as include this topic in other areas of knowledge for a comprehensive understanding of the subject. The hydrates, crystalline solid formed mainly by water and natural gas, are reservoirs of carbon that occur naturally in the continents in permafrost areas, and at sea, in the offshore basins of continental margins. They contain more than twice the total carbon in the world, surpassing the conventional hydrocarbon reserves. Principal energy programs foresee its commercial exploitation by 2015. International research programs include not only the energy aspect, but studying such systems considering their participation in the global carbon cycle, climate change and benthic communities associated with them. In our country, several seismic surveys showed evidence of the presence of gas hydrates in continental shelf and the surrounding area. The first survey was carried out by Brazil in the south of the Brazilian continental shelf, ANCAP then showed the continuity of the hydrate layer on the Uruguayan continental shelf and estimated the gas potential of the mineralized layer (87 TCF). Finally, the BGR survey verified the existence of seismic evidence of gas hydrates layer and the presence of free gas below these. The typical seismic response of gas hydrate and free gas is the BSR (Bottom Simulating Reflector) and is interpreted as a positive intensity reflection, followed by a negative intensity, showing the wave passage from a high acoustic impedance zone to a low acoustic impedance zone.
Environmental Controls on Foliar Respiration in Arctic Plants

description: The Arctic is warming at rapid, unprecedented rates, causing cascading ecological and environmental changes that threaten to destabilize the vast amounts of carbon stored in the vegetation and soils of the tundra. Foliar gas exchange, which is responsible for the initial fixation of carbon, is likely to respond to warming and associated environmental change in tundra plants, though the direction and degree of these responses are not well studied. This dissertation aims to quantify multiple cellular and leaf-level processes underlying carbon cycling in tundra plants, and to address the responses of these processes to abiotic and biotic effects of warming in the Arctic. To assess the impact of environmental change on foliar gas exchange physiology of tundra plants, a series of empirical studies were conducted on common and abundant plant species located near Toolik Lake, on the North Slope of Alaska. Long-term manipulated treatment plots that simulate the effects of climate change in this region, including elevated growth temperature and increased soil nutrient availability, served as the research setting for multiple experiments that addressed the response of variables such as foliar photosynthesis, respiration, photorespiration, mitochondria and chloroplast size and density, and physical leaf traits. Due to the extreme photoperiod experienced by arctic vegetation, respiration in the light (estimated using the Kok method) was quantified in addition to dark respiration for a more accurate depiction of plant carbon fluxes. Individual studies, presented as dissertation chapters, examine the responses of the aforementioned variables to a gradient of soil nitrogen and phosphorus availability; decades-long warming and fertilization; seasonal timing and short-term intra-season temperature fluctuations; and canopy position within a shrub community. Collectively, the results of these studies find respiration to be more sensitive to long- and short-term environmental variation than photosynthesis, indicating a decoupling of the processes controlling foliar carbon cycling. Across all species and environmental conditions, respiration is inhibited by light, emphasizing the need for the estimation of this physiological phenomena and its inclusion in regional terrestrial ecosystem carbon models. Also, foliar carbon fluxes in woody shrub species are significantly higher than non-shrub species across experiments, a finding that demands attention given the general trend of increasing shrub cover associated with warming in the Arctic tundra. The results presented in this study on the environmental controls on leaf-level gas exchange allow for a more thorough understanding of the current carbon balance of this region and provides new data the can inform predictions and models of its future status.

description: We study tunable polaritons in monolayers of silicene, germanene, and stanene (Xenes) via an external electric field in an open optical microcavity whose length can be adjusted. An external electric field applied perpendicular to the plane of the Xene monolayer simultaneously changes the band gap and the exciton binding energy, while the variable length of the open microcavity allows one to keep the exciton and cavity photon modes in resonance. First, the Schrödinger equation for an electron and hole in an Xene monolayer is solved, yielding the eigenergies and eigenfunctions of the exciton as a function of the external electric field. The dependence of the polaritonic properties, such as the Rabi splitting and cavity photon damping, on the external electric field and on the cavity length, is analyzed. The Berezinskii-Kosterlitz-Thouless (BKT) transition temperature of polaritons is calculated as a function of the external electric field. We analyze and present the conditions for a room-temperature superfluid of lower polaritons by simultaneously maximizing the Rabi splitting and BKT transition temperature.
The Consequences of assuming m=0 for Global Model-fitting

description: A recent re-analysis of Whole Earth Telescope observations of GD 358 obtained in 1990 suggests that asteroseismology of additional DBV white dwarfs can lead to independent constraints on the important, but poorly determined, ^{12}C(alpha,gamma)^{16}O nuclear reaction rate. Data exist for several other DBV white dwarfs, but relatively few modes are detected and there is often no multiplet structure to aid in the identification of the spherical harmonic indices (l,m). I use a new grid of one million DBV models covering a broad range of masses, temperatures, and surface helium layer masses to investigate the consequences of assuming m=0 for global model-fitting. I find that when the spherical degree is known and the rotation period is of order 1 day, the model-fitting procedure applied to modes with unknown m-values will still correctly identify the_families_ of possible solutions, and has a high probability of identifying the same globally optimal solution found when the m-value is known.

description: New York City and many other cities around the world are experiencing increasing risks to climate change and its related climate problems. Hurricane Sandy exposed the vulnerability of NYC’s communities with devastating consequences, in which many of them are will come back in the future. Meanwhile, affordable housing as an important component for both the community and city, need to respond to various urban needs and the increasing risks of climate change. As the city looks to be a global leader in fighting against climate change while strive to provide affordable housings to more New Yorkers, it is imperative that city agencies work with communities to plan for a resilient and affordable future. Spring Creek is a waterfront neighborhood in the East New York portion of Brooklyn in New York City, within Brooklyn Community District 5. It is named after Spring Creek, a creek that runs through the area and goes into the Jamaica Bay. Like many other communities in New York City, Spring Creek experienced various kinds of climate and environmental hazards in the last few decades. For example, Industrial activities and lack of tree canopies worsen the Urban Heat Island (UHI) effect and outdoor air pollution. However, similar to all out-lying communities in NYC, Spring Creek is physically isolated from most central city resources. This physical isolation exacerbates resident’s ability to cope with climate hazards if happening, as well as highlights the challenge of limited access to resilient and affordable services and amenities such as housing and healthcare. Partnering with HPD, this capstone project conducted a comprehensive analysis on the level of resilience of an identified study area in the neighborhood of Spring Creek, Brooklyn. By conducting an initial study and an indicator-based resiliency assessment, the project identifies existing risks and hazards prone to the neighborhood, and provides a concept plan with recommended mitigation measures that would help increase the level of resiliency. The purpose of this project is to help HPD envision a livable, sustainable, and affordable future for Spring Creek.
State Space Reconstruction Parameters in the Analysis of Chaotic Time Series - the Role of the Time Window Length

description: The most common state space reconstruction method in the analysis of chaotic time series is the Method of Delays (MOD). Many techniques have been suggested to estimate the parameters of MOD, i.e. the time delay $τ$ and the embedding dimension $m$. We discuss the applicability of these techniques with a critical view as to their validity, and point out the necessity of determining the overall time window length, $τ_w$, for successful embedding. Emphasis is put on the relation between $τ_w$ and the dynamics of the underlying chaotic system, and we suggest to set $τ_w \geq τ_p$, the mean orbital period; $τ_p$ is approximated from the oscillations of the time series. The procedure is assessed using the correlation dimension for both synthetic and real data. For clean synthetic data, values of $τ_w$ larger than $τ_p$ always give good results given enough data and thus $τ_p$ can be considered as a lower limit ($τ_w \geq τ_p$). For noisy synthetic data and real data, an upper limit is reached for $τ_w$ which approaches $τ_p$ for increasing noise amplitude.

description: Judging an action's safety requires knowledge of the context in which the action takes place. To human agents who act in various contexts, this may seem obvious: performing an action such as email deletion may or may not be appropriate depending on the email's content, the goal (e.g., to erase sensitive emails or to clean up trash), and the type of email address (e.g., work or personal). Unlike people, computational systems have often had only limited agency in limited contexts. Thus, manually crafted policies and user confirmation (e.g., smartphone app permissions or network access control lists), while imperfect, have sufficed to restrict harmful actions. However, with the upcoming deployment of generalist agents that support a multitude of tasks (e.g., an automated personal assistant), we argue that we must rethink security designs to adapt to the scale of contexts and capabilities of these systems. As a first step, this paper explores contextual security in the domain of agents and proposes contextual agent security (Conseca), a framework to generate just-in-time, contextual, and human-verifiable security policies.

description: Robust machine learning relies on access to data that can be used with standardized frameworks in important tasks and the ability to develop models whose performance can be reasonably reproduced. In machine learning for healthcare, the community faces reproducibility challenges due to a lack of publicly accessible data and a lack of standardized data processing frameworks. We present MIMIC-Extract, an open-source pipeline for transforming raw electronic health record (EHR) data for critical care patients contained in the publicly-available MIMIC-III database into dataframes that are directly usable in common machine learning pipelines. MIMIC-Extract addresses three primary challenges in making complex health records data accessible to the broader machine learning community. First, it provides standardized data processing functions, including unit conversion, outlier detection, and aggregating semantically equivalent features, thus accounting for duplication and reducing missingness. Second, it preserves the time series nature of clinical data and can be easily integrated into clinically actionable prediction tasks in machine learning for health. Finally, it is highly extensible so that other researchers with related questions can easily use the same pipeline. We demonstrate the utility of this pipeline by showcasing several benchmark tasks and baseline results.

This result is new even when S equals a single Toeplitz operator. Our main result can be used to prove, via a unified approach, several previously known results about compact Toeplitz operators, compact Hankel operators, and appropriate products of these operators.

description: The well-known problem of wormholes in general relativity (GR) is the necessity of exotic matter, violating the Weak Energy Condition (WEC), for their support. This problem looks easier if, instead of island-like configurations, one considers string-like ones, among them, cylindrically symmetric space-times with rotation. However, for cylindrical wormhole solutions a problem is the lacking asymptotic flatness, making it impossible to observe their entrances as local objects in our Universe. It was suggested to solve this problem by joining a wormhole solution to flat asymptotic regions at some surfaces $Σ_-$ and $Σ_+$ on different sides of the throat. The configuration then consists of three regions, the internal one containing a throat and two flat external ones. We discuss different kinds of source matter suitable for describing the internal regions of such models (scalar fields, isotropic and anisotropic fluids) and present two examples where the internal matter itself and the surface matter on both junction surfaces $Σ_\pm$ respect the WEC. In one of these models the internal source is a stiff perfect fluid whose pressure is equal to its energy density, in the other it is a special kind of anisotropic fluid. Both models are free from closed timelike curves. We thus obtain examples of regular twice asymptotically flat wormhole models in GR without exotic matter and without causality violations.

title: Australian and British home ownership policies

Publisher: name: University of Glasgow
Year: 1984
Subjects: subject: Urban planning.

description: This dissertation examines the housing policies of Britain and Australia. It has been suggested that Britain is moving towards an increased level of home ownership, especially with the implementation of the 1980 Housing Act which gave local authority and housing association tenants the right to purchase their homes. As Australia has a high level of home ownership and a policy of selling public sector houses to tenants, it is appropriate to examine the current problems and issues in the Australian housing field and to ascertain the possible implications for British housing policy makers, in the light of the 1980 Act, in order simply not to replicate their failures. Chapter One examines the historical development of Australian housing policy and the emergence of home ownership as the major tenure form. It traces the involvement of the Commonwealth Government in housing policy via the Commonwealth State Housing Agreement (CSHA) which remains the main vehicle for the implementation of housing policy. The first CSHA of 1945 is examined fully as it laid the foundation stone for subsequent Agreements, although those Agreements were to drift away from the original aim of providing rented housing as a priority. Subsequent Agreements and the major policy decisions contained within them are discussed, up to the most recent Agreement of 1981. Chapter Two follows through the historical development of British housing policy with its original concerns with health and sanitation culminating in the 1919 Addison Act. Changes in direction and policy from 1919 through the inter war years, from 1945 up to the 1970's are reviewed. As the 1977 Green Paper and the 1980 Housing Act are central to this piece of work, they are examined and discussed fully. Chapter Three explores the current issues and problems in Australian housing policy, namely the introduction of a market rents policy, the move towards a welfare housing sector, increasing waiting lists for the public sector, sales of public sector stock and concern as to the inequity of subsidies between the two sectors. The notion of a tenure-neutral housing policy is also discussed. Chapter Four discusses the current issues and problems in British housing policy. The crucial issue of the sale of council houses is reviewed in depth. Government intervention, which is central to an understanding of housing policy, is examined along with the question of subsidies. Chapter Five, the concluding chapter, attempts to draw together the issues discussed in previous chapters and to outline the possible implications for British housing policy makers wishing to pursue a policy of home ownership.

description: Polyglycerol (PG) coated polypropylene (PP) films were synthesized in a two- step approach that involved plasma bromination and subsequently grafting hyperbranched polyglycerols with very few amino functionalities. The influence of different molecular weights and density of reactive linkers were investigated for the grafted PGs. Longer bromination times and higher amounts of linkers on the surface afforded long-term stability. The protein adsorption and bacteria attachment of the PP-PG films were studied. Their extremely low amine content proved to be beneficial for preventing bacteria attachment.

description: The outbreak of the new human coronavirus 2019 (HCoV-19/SARS-CoV-2) has caused a pandemic of novel coronavirus disease (COVID-19). Great international efforts have been put into the development of prophylactic vaccines and neutralizing antibodies. However, a systematic profiling of dynamic changes of the patient’s B-cell receptor (BCR) repertoire after being infected by HCoV-19 is still lacking. Here, we report a comprehensive characterization of the dynamics of immunoglobin heavy chain (IGH) repertoire in COVID-19 patients. By using next-generation sequencing technology, we interrogated the landscape of patient’s immunological status over time, featured with dramatic changes of the IGH within the patients’ immune system undergone after symptoms onset. Althouh different patients have distinct immune responses to HCoV-19 infection, through clonotype overlap, lineage expansion and clonotype network analyses, we observed the higher clonotype overlap and substantial lineage expansion of COVID-19 patients during 2-3 weeks of illness, which is of great importance to B-cell immune responses. Meanwhile, for preferences of V gene usage during HCoV-19 infection, IGHV3-74 and IGHV4-34 and IGHV4-39 in COVID-19 patients showed more abundant than that of healthy controls. Overall, we present an immunological resource for HCoV-19 that could promote both therapeutic development and mechanistic research.

description: A multiphysics simulation model incorporating a sintering model coupled with the MultIHeaTS thermal solver was developed to study the evolution of icy moons' microstructure. The sintering process is highly dependent on temperature, and this study represents the first attempt in planetary science to examine the coupled interaction between heat transfer and sintering. Our approach to ice sintering is based upon the literature while offering a refined description of the matter exchange between grains, bonds, and the pore space. By running the numerical framework, we simulate the evolution of ice microstructure on Galilean satellites, specifically tracking the changes in the ice grain and bond radii over time. LunaIcy, our multiphysics model, was applied to study the evolution of Europa's ice microstructure over 1 million yr along its orbit, with a parameter exploration to investigate the diverse configurations of the icy surface. Our results indicate that effective sintering can take place in regions where daily temperatures briefly surpass 115 K, even during short intervals of the day. Such sintering could not have been detected without the diurnal thermal coupling of LunaIcy due to the cold daily mean temperature. In these regions, sintering occurs within timescales shorter than Europa's ice crust age, suggesting that, in present times, their surface is made of an interconnected ice structure.

description: Many electronic structure methods rely on the minimization of the energy of the system with respect to the one-body reduced density matrix (1-RDM). To formulate a minimization algorithm, the 1-RDM is often expressed in terms of its eigenvectors via an orthonormal transformation and its eigenvalues. This transformation drastically alters the energy landscape. Especially in 1-RDM functional theory this means that the convexity of the energy functional is lost. We show that degeneracies in the occupation numbers can lead to additional critical points which are classified as saddle points. Using a Cayley or Householder parametrization for the orthonormal transformation, no extra critical points arise. In case of Given's rotations or the exponential, additional critical points can arise, which are of no concern in practical minimization. These findings provide an explanation for the success of recent minimization procedures using second-order information.

description: The honeybee waggle dance communication system is an intriguing example of abstract animal communication and has been investigated thoroughly throughout the last seven decades. Typically, observables such as waggle durations or body angles are extracted manually either directly from the observation hive or from video recordings to quantify properties of the dance and related behaviors. In recent years, biology has profited from automation, improving measurement precision, removing human bias, and accelerating data collection. We have developed technologies to track all individuals of a honeybee colony and to detect and decode communication dances automatically. In strong contrast to conventional approaches that focus on a small subset of the hive life, whether this regards time, space, or animal identity, our more inclusive system will help the understanding of the dance comprehensively in its spatial, temporal, and social context. In this contribution, we present full specifications of the recording setup and the software for automatic recognition of individually tagged bees and the decoding of dances. We discuss potential research directions that may benefit from the proposed automation. Lastly, to exemplify the power of the methodology, we show experimental data and respective analyses from a continuous, experimental recording of 9 weeks duration.

description: In the late spring of 2008, the Chevron-led Gulf of Mexico Gas Hydrate Joint Industry Project (JIP) expects to conduct an exploratory drilling and logging campaign to better understand gas hydrate-bearing sands in the deepwater Gulf of Mexico. The JIP Site Selection team selected three areas to test alternative geological models and geophysical interpretations supporting the existence of potential high gas hydrate saturations in reservoir-quality sands. The three sites are near existing drill holes which provide geological and geophysical constraints in Alaminos Canyon (AC) lease block 818, Green Canyon (GC) 955, and Walker Ridge (WR) 313. At the AC818 site, gas hydrate is interpreted to occur within the Oligocene Frio volcaniclastic sand at the crest of a fold that is shallow enough to be in the hydrate stability zone. Drilling at GC955 will sample a faulted, buried Pleistocene channel-levee system in an area characterized by seafloor fluid expulsion features, structural closure associated with uplifted salt, and abundant seismic evidence for upward migration of fluids and gas into the sand-rich parts of the sedimentary section. Drilling at WR313 targets ponded sheet sands and associated channel/levee deposits within a minibasin, making this a non-structural play. The potential for gas hydrate occurrence at WR313 is supported by shingled phase reversals consistent with the transition from gas-charged sand to overlying gas-hydrate saturated sand. Drilling locations have been selected at each site to 1) test geological methods and models used to infer the occurrence of gas hydrate in sand reservoirs in different settings in the northern Gulf of Mexico; 2) calibrate geophysical models used to detect gas hydrate sands, map reservoir thicknesses, and estimate the degree of gas hydrate saturation; and 3) delineate potential locations for subsequent JIP drilling and coring operations that will collect samples for comprehensive physical property, geochemical and other analyses

description: The City of Brownsville, Texas’ initiatives have encouraged commercial redevelopment projects that elevate a history of long overlooked treasures within an abandoned downtown. Despite recent downtown revitalization efforts, the area lacks support for residential growth as a redevelopment strategy. Thus, preventing the increase of residential density that encourages downtown reinvestment. Recognizing this need, the Planning & Redevelopment Department (Client) is prompted with a comprehensive technical report on the existing residential conditions and suggestions of potential housing development. First, the project presents a historic and background analysis of downtown growth in the United States and an overview of Downtown Brownsville’s history. It defines Downtown Living by providing a literature review on nationwide housing trends and residential strategies for downtown redevelopment. Then, an analysis on the study area’s relevant demographics, housing trends, and cultural assets reveals Downtown Brownsville’s potential residential demand. The project exposes existing residential conditions through an analysis on Brownsville’s revitalization efforts and the categorization of current residential uses. Its findings inform on the obstacles faced in developing Downtown Brownsville and residents’ downtown living impediments. Lastly, it presents two sets of recommendations. The first set reveals policy and initiatives recommendations, tailored on providing support for residential growth and improving the development process. The second set reveals a set of schematic design models of residential typologies that help envision infill and adaptive reuse housing units within the study area.

Why are the rational and hyperbolic Ruijsenaars-Schneider hierarchies governed by the same R-operators as the Calogero-Moser ones?

description: We demonstrate that in a certain gauge the Lax matrices of the rational and hyperbolic Ruijsenaars--Schneider models have a quadratic $r$-matrix Poisson bracket which is an exact quadratization of the linear $r$--matrix Poisson bracket of the Calogero--Moser models. This phenomenon is explained by a geometric derivation of Lax equations for arbitrary flows of both hierarchies, which turn out to be governed by the same dynamical $R$--operator.

The Semi-Relativistic Equation Via the Shifted-l Expansion Technique
Creators: name: Barakat, T.
Publisher: name: arXiv
Year: 2000
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The semi-relativistic equation is cast into a second-order Schrodinger-like equation with the inclusion of relativistic corrections up to order (v/c)^2. The resulting equation is solved via the shifted-l expansion technique, which has been recently developed to get eigenvalues of relativistic and non-relativistic wave equations. The Coulomb, Oscillator, and the Coulomb-plus-linear potential used in qq-bar phenomenology are tested. The method gives quite accurate results over a wide range of r and any choice of quantum numbers n and l. However, a comparison of the present work with those of Lucha et al. and Nickisch et al. will serve as a test of this approach.
