What Makes an Efficient Physician? Evidence from Florida Emergency Room Visits
Creators: name: Van Parys, Jessica
Publisher: name: Columbia University
Year: 2013
Subjects: Economics

description: This is the first paper to use the quasi-random assignment of patients to physicians in emergency rooms to estimate how physician human capital affects efficiency. It focuses on commonplace medical conditions, where we might not expect patients to receive different care. It finds that physician experience is the primary characteristic that affects efficiency. Experienced physicians perform fewer invasive procedures and charge less per visit, with no differences in health outcomes. There is evidence that high-quality physicians from top-20 medical schools exit the ER over time, so experienced physicians from lower ranked schools are the most efficient providers of urgent, but routine healthcare.

What is the Complexity of the Fredholm Problem of the Second Kind?
Creators: name: Werschulz, Arthur G.
Publisher: name: Columbia University
Year: 1984
Subjects: Computer science

description: This paper deals with the approximate solution of the Fredholm problem Lu = f of the second kind, with f ∈Wr,p(I). Of particular interest is the quality of the finite element method (FEM) of degree k using n inner products of f. The error of the approximation is measured in the Lp (I)-norm. We find that the FEM has minimal error iff k ≥ r - 1. However in the Hilbert case p = 2, there always exists a linear combination (called the spline algorithm) of the inner products used by the FEM which does have minimal error; this holds regardless of whether k ≥ r - 1. We also investigate the case where the inner products used by the FEM are not available. Suppose, however, that we can evaluate f (x) for any x ∈ I. In this case, it is reasonable to consider a finite element method with quadrature (FEMQ), in which the inner products required by the FEM are approximated via numerical quadrature. We prove that the FEMQ has minimal error iff k ≥ r - 1. Moreover, we show that the asymptotic penalty for using the FEM or FEMQ with a value of k that is too small is unbounded.
Modification of the Gay-Berne potential for improved accuracy and speed

Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: A modification of the Gay-Berne potential is proposed which is about 10% to 20% more speed efficient (that is, the original potential runs 15% to 25% slower, depending on architecture) and statistically more accurate in reproducing the energy of interaction of two linear Lennard-Jones tetratomics when averaged over all orientations. For the special cases of end-to-end and side-by-side configurations, the new potential is equivalent to the Gay-Berne one.

Parametrization of Newton's iteration for computations with structured matrices and applications
Creators: name: Pan, Victor

Subjects: Computer science

description: We apply a new parametrized version of Newton's iteration in order to compute (over any field F of constants) the solution, or at least-squares solution, to linear system Bx = v with an n × n Toeplitz or Toeplitz-like matrix B, as well as the determinant of B and the coefficients of its characteristic polynomial, det(λI âˆ’ B), dramatically improving the processor efficiency of the known fast parallel algorithms. Our algorithms, together with some previously known and some recent results of [1““5], as well as with our new techniques for computing polynomial god's and lcm's, imply respective improvement of the known estimates for parallel arithmetic complexity of several fundamental computations with polynomials, and with both structured and general matrices.

description: Here is presented recalculated value of the mass of Ceres, based on explicit tracking of its gravitational influence on orbits evolution of 21 selected asteroids during their mutual close encounters (CE). It was applied a new modified method (MM) for mass determination, based on the connecting of pre-encounter observations to the orbit determined from post-encounter ones. The calculated weighted mean value of Ceres mass, based on modified method, is $(4.54\pm0.07)\,10^{-10}M_{\odot}$ while standard procedure (SM) provided result of $(4.70\pm0.04)\,10^{-10}M_{\odot}$. We found that correlation between individual estimated masses based on modified and standard method is 0.78, which confirms reliability of using modified method.

description: We present an interaction model enabling data-source probes and action-based gauges to communicate using an intelligent event model known as ActEvents. ActEvents build on conventional event concepts by associating structural and semantic information with raw data, thereby allowing recipients to be able to dynamically understand the content of new kinds of events. Two submodels of ActEvents are proposed: SmartEvents, which are XML-structured events containing references to their syntactic and semantic models, and Gaugents, which are heavier but more flexible intelligent mobile software agents. This model is presented in light of DARPA's DASADA program, where ActEvents are used in a larger-scale subsystem, called KX, which supports continual validation of distributed, component-based systems. ActEvents are emitted by probes in this architecture, and propagated to gauges, where 'measurements' of the raw data associated with probes are made, thereby continually determining updated target-system properties. ActEvents are also proposed as solutions for a number of other applications, including a distributed collaborative virtual environment (CVE) known as CHIME.

description: The purpose of this Master's Degree Project is to determine what adaptations to conventional downtown revitalization strategies are necessary to turn a downtown in a medium sized satellite city into a vibrant, pedestrian-friendly area. The City of Airdrie is used as a case study. To this end, the MDP examines the conventional downtown redevelopment strategies. An analysis of these strategies indicates that there are inherent assumptions in the literature which make these strategies insufficient for downtown redevelopment in a satellite city. These assumptions include a particular historical trajectory, spatial location of the city, city size. As the literature has a USA bias, additional case studies from Alberta investigate what downtown redevelopment strategies are being utilized more locally. The literature review leads to the development of a new analytical framework for examining satellite city downtown redevelopment. That framework emphasizes locational advantages while addressing the spatial economy, pedestrian flow generation, urban design and stakeholder participation. This project proposes that successful downtown redevelopment in a satellite city requires a modified approach.

description: The Cecotti-Fendley-Intriligator-Vafa (CFIV) index in two-dimensional ${\mathcal N} =(2,2)$ models is revisited. We address the problem of "elementary" (nontopological) excitations over a kink solution, in the one-kink sector (using the Wess-Zumino or Landau-Ginzburg models with two vacua as examples). In other words, we limit ourselves to the large-$β$ limit. The excitation spectrum over the BPS-saturated at the classical level kink is discretized through a large box with judiciously chosen boundary conditions. The boundary conditions are designed in such a way that half of supersymmetry is preserved as well as the BPS kink itself, and relevant zero modes. The excitation spectrum acquires a mass gap. All (discretized) excited states enter in four-dimensional multiplets (two bosonic states + two fermionic). Their contribution to $\mathrm{ind}_{\rm CFIV}$ vanishes level by level. The ground state contribution produces $|\mathrm{ind}_{\rm CFIV}|=1$.

description: We consider a theory of massless reduced quantum electrodynamics (RQED$_{d_γ,d_e}$), e.g., a quantum field theory where the U(1) gauge field lives in $d_γ$-spacetime dimensions while the fermionic field lives in a reduced spacetime of $d_e$ dimensions ($d_e \leqslant d_γ$). In the case where $d_γ=4$ such RQEDs are renormalizable while they are super-renormalizable for $d_γ<4$. The 2-loop electromagnetic current correlation function is computed exactly for a general RQED$_{d_γ,d_e}$. Focusing on RQED$_{4,3}$, the corresponding $β$-function is shown to vanish which implies the scale invariance of the theory. Interaction correction to the 1-loop vacuum polarization, $Π_1$, of RQED$_{4,3}$ is found to be: $Π= Π_1 (1 + 0.056 \al)$ where $\al$ is the fine structure constant. The scaling dimension of the fermion field is computed at 1-loop and is shown to be anomalous for RQED$_{4,3}$.

Optimizing Top-K Selection Queries over Multimedia Repositories

Publisher: name: Columbia University
Year: 2002
Subjects: Computer science

description: Repositories of multimedia objects having multiple types of attributes (e.g., image, text) are becoming increasingly common. A query on these attributes will typically request not just a set of objects, as in the traditional relational query model (filtering), but also a grade of match associated with each object, which indicates how well the object matches the selection condition (ranking). Furthermore, unlike in the relational model, users may just want the k top-ranked objects for their selection queries, for a relatively small k. In addition to the differences in the query model, another peculiarity of multimedia repositories is that they may allow access to the attributes of each object only through indexes. In this paper, we investigate how to optimize the processing of top-k selection queries over multimedia repositories. The access characteristics of the repositories and the above query model lead to novel issues in query optimization. In particular, the choice of the indexes used to search the repository strongly influences the cost of processing the filtering condition. We define an execution space that is search-minimal, i.e., the set of indexes searched is minimal. Although the general problem of picking an optimal plan in the search-minimal execution space is NP-hard, we present an efficient algorithm that solves the problem optimally when the predicates in the query are independent. We also show that the problem of optimizing top-k selection queries can be viewed, in many cases, as that of evaluating more traditional selection conditions. Thus, both problems can be viewed together as an extended filtering problem to which techniques of query processing and optimization may be adapted.

The Automatic Inversion of Attribute Grammars

Publisher: name: Columbia University
Year: 1984
Subjects: Computer science

description: Over the last decade there has developed an acute awareness of the need to introduce abstraction and mathematical rigor into the programming process. This increased formality allows for the automatic manipulation of software, increasing productivity and, even more importantly, the manageability of complex systems. Along these lines, attribute grammars constitute a formal mechanism (or specifying translations between languages; from a Cormal description of the translation a translator can be automatically constructed. In this paper we consider taking this process one step further: given an attribute grammar specifying the translation from language L1 to the language L2, we address the question of whether the inverse attribute grammar specifying the inverse translation from L2 to L1 can be automatically generated. We show how to solve this problem for a restricted subset of attribute grammars. This inversion process allows for compatible two-way translators to be generated from a single description. To show the practical feasibility of attribute grammar inversion, we relate our experience in inverting an attribute grammar used as an interface for a formal database accessing language, SQL. The attribute grammar is used to paraphrase SQL database queries in English.
Optimal Policy for Blood Inventory Management Problem

description: Blood units that are used for transfusion can be stored for a limited amount of time. The blood that is older than 42 days must be discarded. In order not to face shortage usually the oldest blood is used. But the risk of complications after surgery is growing as the age of used blood is growing as well. In this work we find the optimal policy to use blood for transfusion for two blood types. The main goal is to find the policy that will reduce the shortage and minimize the risk of complications at the same time. For this purpose, we use two methods (Linear Programming and Approximate Dynamic Programming) and compare the results of two approaches.
Integrin-linked kinase is an essential mediator of ERG-induced epithelial-to-mesenchymal transition in prostate cancer models
Creators: name: Becker Dos Santos, Daiana
Publisher: name: University of British Columbia
Year: 2011

description: Approximately 50% of human prostate cancers carry a gene fusion involving the 5' untranslated region of TMPRSS2, an androgen-regulated gene, and the protein-coding sequences of ERG, which encodes an ETS transcription factor. Exogenous expression of ERG in human prostatic epithelial cell lines (PrECs) promotes phenotypic changes associated with epithelial-to-mesenchymal transition (EMT), a process implicated in the invasion and metastasis of carcinomas. To gain insight into the biological mechanism by which ERG promotes EMT, I used two immortalized PrECs stably infected with a lentiviral vector expressing a Flag epitope-tagged ERG3 (fERG-PrECs). qRT-PCR and Western blotting show that integrin-linked kinase (ILK) mRNA and protein levels are increased in fERG-PrECs. The mesenchymal markers and downstream effectors of ILK, LEF-1 and Snail, are also upregulated in fERG-PrECs. Depletion of ILK expression by siRNA or inhibition of its activity with a highly selective small molecule inhibitor, QLT-0267, results in a substantial decrease in ERG-mediated upregulation of Snail and LEF-1. Furthermore, I show that inhibition of ILK activity impairs the in vitro invasive properties and suppresses the anchorage-independent growth of fERG-PrECs. In conclusion, I have provided novel insights into critical pathways by which aberrant ERG expression may promote prostate cancer progression. In particular, I presented evidence to support the hypothesis that ERG-mediated oncogenesis in prostate cancer involves activation of ILK signaling, leading to key cancer-promoting phenotypic effects, such as EMT.

description: Coherent light beams composed of ultrashort pulses are now increasingly used in different fields of Science, from time-resolved spectroscopy to plasma physics. Under the effect of even simple optical components, the spatial properties of these beams can vary over the duration of the light pulse. In this letter, we show how such spatio-temporally coupled electromagnetic fields can be exploited to produce an attosecond lighthouse, i.e. a source emitting a collection of isolated attosecond pulses, propagating in angularly well-separated light beams. This very general effect not only opens the way to a new generation of attosecond light sources, particularly suitable for pump-probe experiments, but also provides a powerful new tool for ultrafast metrology, for instance giving direct access to fluctuations in the phase of the laser field oscillations with respect to the pulse envelop, right at the focus of even the most intense ultrashort laser beams.

Fuzzy logic particle filter for high-performance targets tracking in track-while-scan radar
Creators: name: Kamel, Hazem Zakareya Fahim
Publisher: name: University of Calgary
Year: 2006

description: Bibliography: p. 181-189
description: The efficiency and accuracy of the particle filter and its extensions depend mainly on two key factors: the propagation function used to re-allocate the particles and the number of particles used to estimate the posterior distribution. Previous studies have failed to consider these two factors together. In this thesis, a new self adaptive fuzzy logic particle filter (FLPF) that uses fuzzy logic systems (FLS) is proposed. It estimates the angular turn rate, which is included as a state component, and tunes dynamically the number of particles used to estimate the posterior distribution. The estimated angular turn rate defines the propagation function used to re-allocate the particles. Also, the number of particles used to estimate the posterior distribution is measured using FLS based on the target's maneuverability. Thus, the FLPF can improve the efficiency and accuracy of the particle filter by estimating the two key factors simultaneously using a fuzzy-logic framework. Also in this thesis, a tracker fusion technique is proposed to reduce the computation load when the target is non-maneuvering by using the unscented Kalman filter (UKF) as it has less computational load compared to the particle filters. The UKF is known to be optimal and is employed for state estimation for linear and Gaussian systems. Data association is also considered in this thesis as it is a crucial element and one of the most important components of any track-while-scan (TWS) radar system. A merged probabilistic data association (MPDA) is proposed. It merges the probabilistic nearest-neighbor filter (PNNF) with the joint probabilistic data association (JPDA) approach. The MPDA cooperates with the UKF to track non-maneuvering targets; meanwhile the independent sample based joint probabilistic data association (ISBJPDA) approach cooperates with the FLPF to track maneuvering targets. Different scenarios are simulated to evaluate and analyze the performance of the FLPF algorithm, the MPDA approach, and the tracker fusion technique. The experimental results verify that the proposed MPDA outperforms other data association techniques when applied to dense clutter environments and higher noise levels. Also, the FLPF show better performance compared to the integrated multiple models (IMM) in tracking high-performance maneuvering targets.

description: In North American Cities with a winter climate, the use of the bicycle drops dramatically during the winter season. The thesis of this research, is that the drop in ridership is not determined solely by climate. Climactic variables will likely always cause some effect, however, If bikeways are properly maintained and designed, the effect of the winter will be far less dramatic. A case study of the city of Calgary was conducted using a survey of cyclists to the Central Business District as the principal research instrument. This determines characteristics of winter cyclists and along with the literature review, provides the basis for a strategy to increase winter cycling in that city. Calgary retains a high number of winter cyclists compared with other Canadian municipalities, with 47% of cyclists commuting year round. Winter cyclists in Calgary tend to be male, located slightly closer to their destinations and tend to cycle because they believe it is faster than other modes of travel. The high number of cyclists retained is believed to be due to the existence of a high quality pathway that is cleared of snow, that directly links outlying communities with the Central Business District.

description: In this article, we consider how important developments in game theory have contributed to the theory of industrial organization. Our goal is not to survey the theory of industrial organization; rather, we consider the contribution of game theory through a careful discussion of a small number of topics within the industrial organization field. We also identify some points in which developments in the theory of industrial organization have contributed to game theory. The topics that we consider are: commitment in two-stage games and the associated theories of strategic-trade policy and entry deterrence; asymmetric-information games and the associated theories of limit pricing and predation; repeated games with public moves and the associated theory of collusion in markets with public demand fluctuations; mixed-strategy equilibria and purification theory and the associated theory of sales; and repeated games with imperfect monitoring and the associated theory of collusion and price wars. We conclude with a general assessment concerning the contribution of game theory to industrial organization.

In both cases the Higgs field and the U(1) vortex connection are constructed directly from the Riemannian data of the surface corresponding to the sinh--Gordon or the Tzitzeica equation. Radially symmetric solutions lead to vortices with a topological charge equal to one, and the connection formulae for the resulting third Painlevé transcendents are used to compute explicit values for the strength of the vortices.

An Extensible Meta-Learning Approach for Scalable and Accurate Inductive Learning
Creators: name: Chan, Philip K.
Publisher: name: Columbia University
Year: 1996
Subjects: Computer science

description: Much of the research in inductive learning concentrates on problems with relatively small amounts of data. With the coming age of ubiquitous network computing, it is likely that orders of magnitude more data in databases will be available for various learning problems of real world importance. Some learning algorithms assume that the entire data set fits into main memory, which is not feasible for massive amounts of data, especially for applications in data mining.One approach to handling a large data set is to partition the data set into subsets, run the learning algorithm on each of the subsets, and combine the results. Moreover, data can be inherently distributed across multiple sites on the network and merging all the data in one location can be expensive or prohibitive. In this thesis we propose, investigate, and evaluate a meta-learning approach to integrating the results of multiple learning processes. Our approach utilizes machine learning to guide the integration. We identified two main meta-learning strategies:{\it combiner} and {\it arbiter}. Both strategies are independent to the learning algorithms used in generating the classifiers. The combiner strategy attempts to reveal relationships among the learned classifiers' prediction patterns. The arbiter strategy tries to determine the correct prediction when the classifiers have different opinions. Various schemes under these two strategies have been developed. Empirical results show that our schemes can obtain accurate classifiers from inaccurate classifiers trained from data subsets. We also implemented and analyzed the schemes in a parallel and distributed environment to demonstrate their scalability.

description: We consider full implementation in abstract complete-information environments when agents have an arbitrarily small preference for honesty. We offer a condition called separable punishment and show that when it holds and there are at least two agents, any social choice function can be implemented by a simple mechanism in two rounds of iterated deletion of strictly dominated strategies. We also extend our result to settings of incomplete information so long as there is non-exclusive information.

description: Traditional CFD results have a number of freestream inputs. In the physical world, these input conditions often have some uncertainty associated with them. However, this uncertainty is often omitted from the CFD results. The effects of uncertainty in CFD can be determined through application of Uncertainty Quantification (UQ). The primary objective of the present work is to determine the effect of uncertainty in freestream turbulence intensity (FSTI) on the coefficients of lift, drag, and moment for four different airfoils: S809, NACA 0012, SC1095, and RC(4)-10. In this work, the Monte Carlo method is used to calculate the sensitivities of the aerodynamic coefficients to Gaussian distributions of uncertainty in FSTI over a range of angles of attack (AOA) at various Reynolds numbers and Mach numbers. However, the Monte Carlo method would require hundreds of thousands of CFD calculations in order to converge to the correct results. A surrogate surface is therefore generated using a parametric study using the in-house flow solver OVERTURNS. Rather than run a separate CFD run for each Monte Carlo run, all of the results can be attained virtually instantaneously via the surrogate surface. The UQ analysis shows how varying these parameters affects the sensitivies of the aerodynamic coefficients to uncertainty in FSTI. In most cases, the response is nearly Gaussian and the mean response is not too dierent from the discrete FSTI response without uncertainty. However, the output standard deviation for drag and pitching moment can become large when the transition location changes rapidly with changing FSTI.

Syncretism: The Politics of Japan’s Financial Reforms

description: This paper examines how diversely organized capitalist societies evolve by analyzing the transformation of Japan’s financial system since the 1990s. The banking, securities, and insurance, as well as the postal financial institutions changed significantly, but are hardly converging to Anglo-American or ‘liberal market’ models. We contend that Japan’s new financial system is best characterized as syncretic, with new, traditional and hybrid forms of practices, organizations and norms coexisting. Syncretism in industry was driven by a distinctive pattern of interest group politics we call syncretization. Strong political leadership, facing serious electoral threats, shifted the policy logic from gradual incremental reforms following traditional interest group dynamics, to rapid reforms that excluded the traditionally powerful interest groups most affected by these reforms. We support the notion that diverse industry outcomes can be complementary to broader political economy reforms that take Japan away from its traditional model, part of a broader ‘convergence towards diversity’.
Parent- and Teacher-Rated Social Skills and Theory of Mind in Kindergarteners

description: This study investigated how kindergartners’ use of Theory of Mind (ToM; understanding and inferring others’ mental states to predict and explain behavior) relate to their Social Competence (SC), as rated by parents and teachers. This study aimed to determine whether social skills items could be classified as more or less conventional (knowledge of emotions and social conventions) or intentional (requires noticing and interpreting other’s beliefs and intentions) based on their correlates with more or less structured performance measures of ToM, respectively. Results partially supported this this distinction. Patterns suggested that parents and teachers judge children’s social skills differently. This study also explored relations of language with SC and ToM. Language accounted for much of the variance in the more structured ToM task and teacher-rated social skills, but not the less structured ToM task or parent-rated social skills. Implications for SC conceptualization and scale construction and interpretation are discussed.
Chaoticity and Shell Effects in the Nearest-Neighbor Distributions

description: Statistics of the single-particle levels in a deformed Woods-Saxon potential is analyzed in terms of the Poisson and Wigner nearest-neighbor distributions for several deformations and multipolarities of its surface distortions. We found the significant differences of all the distributions with a fixed value of the angular momentum projection of the particle, more closely to the Wigner distribution, in contrast to the full spectra with Poisson-like behavior. Important shell effects are observed in the nearest neighbor spacing distributions, the larger the smaller deformations of the surface multipolarities.

description: As part of an intense effort to clean up the Anacostia River and the Chesapeake Bay region, the Maryland Department of Environment will soon enforce new policies to increase the treatment of impervious areas. The University of Maryland’s College Park campus needs to identify potential projects in order to meet the pending stormwater regulations as part of the new municipal separate storm sewer systems (MS4) permit for UM-CP. This thesis investigates retrofits a poorly maintained stormwater pond that has maintained itself as a wetland. The 4.89-acre site is located in the north part of campus is a part of the Anacostia watershed and includes the pond, two parking lots, and a wet swale. This thesis proposes a stormwater retrofit that includes various state acceptable BMPs including: a constructed wetland, mirco-bioretentions, pervious concrete, and a bio-swale. The BMPs forms a treatment train that reducing runoff by 7%, capturing and treating 113% of a one-year storm of 2.63 inches. This redesign that would provide a range of environmental, recreational, and educational services. While the proposal is site-specific, the model can be adaptable for retrofitting centralized stormwater facilities and by other college campuses within the Chesapeake Bay watershed.
Novel Fermi Liquid of 2D Polar Molecules

description: We study Fermi liquid properties of a weakly interacting 2D gas of single-component fermionic polar molecules with dipole moments $d$ oriented perpendicularly to the plane of their translational motion. This geometry allows the minimization of inelastic losses due to chemical reactions for reactive molecules and, at the same time, provides a possibility of a clear description of many-body (beyond mean field) effects. The long-range character of the dipole-dipole repulsive interaction between the molecules, which scales as $1/r^3$ at large distances $r$, makes the problem drastically different from the well-known problem of the two-species Fermi gas with repulsive contact interspecies interaction. We solve the low-energy scattering problem and develop a many-body perturbation theory beyond the mean field. The theory relies on the presence of a small parameter $k_Fr_*$, where $k_F$ is the Fermi momentum, and $r_*=md^2/\hbar^2$ is the dipole-dipole length, with $m$ being the molecule mass. We obtain thermodynamic quantities as a series of expansion up to the second order in $k_Fr_*$ and argue that many-body corrections to the ground-state energy can be identified in experiments with ultracold molecules, like it has been recently done for ultracold fermionic atoms. Moreover, we show that only many-body effects provide the existence of zero sound and calculate the sound velocity.

Optimal taxation of entrepreneurial capital with private information

Entrepreneurship

description: This paper studies optimal taxation of entrepreneurial capital with private information and multiple assets. Entrepreneurial activity is subject to a dynamic moral hazard problem and entrepreneurs face idiosyncratic capital risk. We first characterize the optimal allocation subject to the incentive compatibility constraints resulting from the private information. The optimal tax system implements such an allocation as a competitive equilibrium for a given market structure. We consider several market structures that differ in the assets or contracts traded and obtain three novel results. First, differential asset taxation is optimal. Marginal taxes on bonds depend on the correlation of their returns with idiosyncratic capital risk, which determines their hedging value. Entrepreneurial capital always receives a subsidy relative to other assets in the bad states. Second, if entrepreneurs are allowed to sell equity, the optimal tax system embeds a prescription for double taxation of capital income at the firm level and at the investor level. Finally, we show that taxation of assets is essential even with competitive insurance contracts, when entrepreneurial portfolios are also unobserved.
