description: In this note the order reduction phenomenon of diagonally implicit Runge-Kutta methods (DIRK--methods) and Rosenbrock--Wanner methods (ROW--methods) applied on the Prothero-Robinson example is analysed. New order conditions to avoid order reduction are derived and a new second order DIRK and ROW--method is created. The new schemes are applied on the Prothero--Robinson example and on the semi-discretised
incompressible Navier--Stokes equations. Numerical examples show that the
new methods converge with second order for velocity and pressure.

Parents Speak: An Ethnographic Study of Autism Parents
Creators: de Wolfe, Juliette Lynn
Publisher: name: Columbia University
Year: 2013
Subjects: subject: Education
subject: Anthropology
subject: FOS: Sociology

description: This ethnography documents the everyday experiences of the parents of children diagnosed with autism with whom I conducted fieldwork from April 2010 through September 2011.  It describes the daily activities of self proclaimed "autism parents" living in Queens, New York, who tirelessly campaign for their children's medical, educational, and social needs.  The parents described are all members of a local support group, and together, they engage in practices of self-education, advocacy, and activism.  By recounting parents' stories, this ethnography demonstrates the difficulties of the early moments of becoming an autism parent: the official diagnosis, receiving Early Intervention services, and navigating relationships with friends, family and loved ones.  Through descriptive fieldnotes from the 18-month study, it also interrogates the uniqueness of parents' circumstances as they are shaped by their children's bodies and their own bodies, and urges the reader to think about the peculiarities of bodies and the particularities of the situations in which they find themselves.  Furthermore this ethnography traces the navigational obstacles parents face as they work to secure educational and medical services for their children. Finally, the project examines the educative practices that parents engage in as they learn from each other, tell their stories to others, and work to express their experiences with autism to the world.  The content presented in each chapter works to answer the question, "how does one become and be an autism parent?" by demonstrating that the paths of autism parenthood are multiple, varied, and textured - each a unique autism experience.

description: Recognizing the patterns of citation and material usage in thesis writing, this research intends to identify the researcher’s needs for data in History area by citation analysis. The output taken from PhD thesis on History at Al-Zahra University would highly contribute to History research and studies. Employing citation analysis method, the research studies on bibliography in 25 thesis from 1380 to 1391 (Solar Calendar) with a total citation of 5949 by applying Microsoft Excel. Findings: It seems that books, having 4736 calls (79.61%), possess the highest rank in citation while Persian resource, with 3414 calls (57.39%) is the first among other language resource such as Arabic , with 2035 calls (34.21%). The field “History of Islamic Iran” assigned the largest number of citation to itself with almost 57.25% as well as comparing to the field “History of Islam” the average half-life of books cited in the former field is 10.97 to 9.90 in the latter. Moreover, the average half-life of total journals cited in the former field is 8.62 when the average in the latter field is 7.95. The findings also show that books have been the main accesible source with the emphasis on compiled rather than translated works. Cited journals and periodicals in Persian have been more up-to-date comparing with Arabic and Latin ones.

description: Lunar laser ranging (LLR) data and Apollo seismic data analyses, revealed independent evidence for the presence of a fluid lunar core. However, the size of the lunar fluid core remained uncertain by $\pm55$ km (encompassing two contrasting 2011 Apollo seismic data analyses). Here we show that a new description of the lunar interior's dynamical model provides a determination of the radius and geometry of the lunar core-mantle boundary (CMB) from the LLR observations. We compare the present-day lunar core oblateness obtained from LLR analysis with the expected hydrostatic model values, over a range of previously expected CMB radii. The findings suggest a core oblateness ($f_c=(2.2\pm0.6)\times10^{-4}$) that satisfies the assumption of hydrostatic equilibrium over a tight range of lunar CMB radii ($\mathcal{R}_{CMB}=381\pm12$ km). Our estimates of a presently-relaxed lunar CMB translates to a core mass fraction in the range of $1.59-1.77\%$ with a present-day Free Core Nutation (FCN) within $(367\pm100)$ years.

description: We introduce a precise notion, in terms of few Schlessinger's type conditions, of extended deformation functors which is compatible with most of recent ideas in the Derived Deformation Theory (DDT) program and with geometric examples. With this notion we develop the (extended) analogue of Schlessinger and obstruction theories. The inverse mapping theorem holds for natural transformations of extended deformation functors and all such functors with finite dimensional tangent space are prorepresentable in the homotopy category.

On the star formation efficiency in high redshift Lyman-α emitters

Year: 2019
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present semi-analytical models of high redshift Lyman-α emitters (LAEs) in order to constrain the star formation efficiency in those galaxies. Our supernova feedback induced star formation model along with Sheth-Tormman halo mass function correctly reproduces the shape, amplitude and the redshift evolution of UV and Lyman-α luminosity functions of LAEs in the redshift range z = 2 to 7.3. We show that the fraction of Lyman-α emitting galaxies increases with increasing redshifts reaching to unity just after the reionisation. However, we show that star formation efficiency in those LAEs does not show any redshift evolution within the uncertainty in available observations. This would have significant repercussion on the reionisation of the intergalactic medium.

Miss Fortune X is the name of a radio controlled model airplane my father built and flew several iterations of throughout his lifetime. The work uses segments of the base plan as a guide for the construction of the score, and in more detail, the piano part, where an e-bow and roughened plectrums are used to alter the timbre of the instrument. The original plan, from a magazine, had been copied and resized many times over many years, creating a layer of visual noise in later copies which is also included as musical material for the work. The piece continues my explorations of drone and glissandi, and the sonic colour of radio static, which carries a new metaphorical meaning in this work. It is dedicated to Douglas Campbell Hope (1937 – 2012).

A digital or hard copy of the score is available from Material Press.

description: “Parsing Truth in Merovingian Gaul: Evidence and the Early Medieval Critic” considers how people distinguished truth from falsehood in a set of post-Roman kingdoms occupying much of modern France and western Germany from c. 450 to 751. Using Merovingian saints’ lives, legal documents, law codes, letters, and theological and philosophical texts, I consider how people and institutions navigated the possibility that information might be presented with the intent to deceive, or might just be wrong. Responses to questions about the reliability of information ranged from the practical to the abstractly epistemological, and the period produced multiple and contradictory arguments about how knowledge could, indeed, be certain. The dissertation concludes by examining some points of contact between Merovingian critical practices and Early Modern ones, looking specifically at the management of knowledge about relics at Sens.
Modified calibration strategies and parameter regionalization potential for streamflow estimation using a hydrological model

description: Calibration and regionalization are two key tasks in hydrological modelling, and the availability of increased data and computing resources has enhanced our ability to complete these tasks. This paper addresses both tasks, i.e. (i) it proposes novel model structure-based calibration strategies with the goal to improve estimation of high streamflows, and (ii) it explores the association of soil hydraulic properties with optimal parameters to estimate streamflows in ungauged catchments. Both tasks are demonstrated by employing a conceptual hydrological model, Sacramento Soil Moisture Accounting (SAC-SMA), on multiple catchments in the Narmada River Basin. The initial calibrated model exhibited good model performance, with high flows being underestimated. Seven calibration strategies via revising parameter space are explored, and improvement in high flow performance is observed at nine out of 12 catchments. Estimated streamflows based on soil hydraulic parameters demonstrate regionalization potential. The results indicate successful application of the proposed methods which are transferable to other basins.
Part 1. Diaziridinium Ions: First Reported Synthesis and Reactivity Studies.  Part 2. Tropylium Ion Mediated alpha-Cyanation of Amines.  Part 3. Multicatalytic Synthesis of Complex Tetrahydrofurans

description: The first synthesis and full characterization of a new functionality, called the diaziridinium ion, is reported.  The original synthetic intent behind its design was to explore its potential use as a non-metal based N-transfer reagent.  During this study, we have uncovered a practical rearrangement to access 2,3-benzodiazepines reliably and efficiently.  Efforts to achieve N-transfer from these species are described and are ongoing. We have identified the tropylium ion as a highly efficient organic-based amine oxidant and have demonstrated its practical use in a one-pot protocol for alpha-aminonitrile synthesis.  We also report an application of this new oxidant towards an aza-Cope rearrangement. Finally, we report a multicatalytic method that uses bismuth(III) triflate to catalyze a nucleophilic addition to an aldehyde followed by hydroalkoxylation to generate highly functionalized tetrahydrofuran rings, a motif that is often encountered in natural product architectures.

Integrating neural networks into the blind deblurring framework to compete with the end-to-end learning-based methods

description: Recently, end-to-end learning-based methods based on deep neural network (DNN) have been proven effective for blind deblurring. Without human-made assumptions and numerical algorithms, they are able to restore images with fewer artifacts and better perceptual quality. However, in practice, we also find some of their drawbacks. Without the theoretical guidance, these methods can not perform well when the motion is complex and sometimes generate unreasonable results. In this paper, for overcoming these drawbacks, we integrate deep convolution neural networks into conventional deblurring framework. Specifically, we build Stacked Estimation Residual Net (SEN) to estimate the motion flow map and Recurrent Prior Generative and Adversarial Net (RP-GAN) to learn the implicit image prior in the optimization model. Comparing with state-of-the-art end-to-end learning-based methods, our method restores reasonable details and shows better generalization ability.

Year: 2010

description: In 2003 a waterway swale was retrofitted into an Alberta oil sands overburden dump. In spring 2004, Terra Erosion Control Limited was retained to develop and implement an erosion control prescription using a soil bioengineering approach. Repair and maintenance work were carried out in 2005 and 2006. The site was monitored in 2005, 2006, 2007 and 2009, results demonstrated that the use of contour fascines type structures were more efficient at dispersing intermittent water flow than brush sills. Overall the work was considered to be successful in preventing accelerated gully formation in the swale, as well as creating wildlife habitat.

description: We study the problem of satisfiability of randomly chosen clauses, each with K Boolean variables. Using the cavity method at zero temperature, we find the phase diagram for the K=3 case. We show the existence of an intermediate phase in the satisfiable region, where the proliferation of metastable states is at the origin of the slowdown of search algorithms. The fundamental order parameter introduced in the cavity method, which consists of surveys of local magnetic fields in the various possible states of the system, can be computed for one given sample. These surveys can be used to invent new types of algorithms for solving hard combinatorial optimizations problems. One such algorithm is shown here for the 3-sat problem, with very good performances.

Part 1: Lanthanum(III) Triflate-Catalyzed Cyclopropanation via Intramolecular Methylene Transfer. Part 2: Reaction Design with Aromatic Ions - Nucleophilic Acyl Substitution and Organophotoredox Catalysts
Creators: Hardee, David James
Publisher: name: Columbia University
Year: 2011
Subjects: Chemistry, Organic

description: This thesis describes the development of novel synthetic methods in the areas of methylene transfer cyclopropanation and reaction design with aromatic cations. The first chapter presents a new cyclopropanation method involving intramolecular methylene transfer from an epoxide to an olefin. The lanthanum(III) triflate-catalyzed process proceeds with high stereoselectivity and a range of examples are presented to illustrate the reaction scope. An asymmetric cyclopropane synthesis combining enantioselective epoxidation and the methylene transfer protocol is also presented. The second chapter describes the application of aromatic cation activation for nucleophilic acyl substitution. The strategy is used to rapidly convert carboxylic acids to their corresponding acid chlorides with dichlorocyclopropene reagents. The effect of cyclopropene substituents and amine base additives on the rate of conversion is examined. A mild amidation protocol employing acid chloride formation is described and applied to acid-sensitive substrates and preparative peptide couplings. The final chapter discloses the development of aromatic cation photoredox catalysts. Investigations into the relationship between cyclopropenium substitution and ultraviolet/visible light absorption are presented. Cyclopropenium ions are shown to be effective photocatalysts for a variety of photoredox transformation.

description: To evaluate their performance, existing dehazing approaches generally rely on distance measures between the generated image and its corresponding ground truth. Despite its ability to produce visually good images, using pixel-based or even perceptual metrics do not guarantee, in general, that the produced image is fit for being used as input for low-level computer vision tasks such as segmentation. To overcome this weakness, we are proposing a novel end-to-end approach for image dehazing, fit for being used as input to an image segmentation procedure, while maintaining the visual quality of the generated images. Inspired by the success of Generative Adversarial Networks (GAN), we propose to optimize the generator by introducing a discriminator network and a loss function that evaluates segmentation quality of dehazed images. In addition, we make use of a supplementary loss function that verifies that the visual and the perceptual quality of the generated image are preserved in hazy conditions. Results obtained using the proposed technique are appealing, with a favorable comparison to state-of-the-art approaches when considering the performance of segmentation algorithms on the hazy images.

description: Calibration and regionalization are two key tasks in hydrological modelling, and the availability of increased data and computing resources has enhanced our ability to complete these tasks. This paper addresses both the tasks, i.e., (i) it proposes novel, model structure based calibration strategies with a goal to improve estimation of high streamflows, and (ii) it explores soil hydraulic properties’ association with optimal parameters to estimate streamflows in ungauged catchments. Both the tasks are demonstrated employing a conceptual hydrological model, SAC-SMA, on multiple catchments in the Narmada River Basin. The initial calibrated model exhibited good model performance with high flows being underestimated. Seven calibration strategies by revising parameter space are explored, and improvement in high flows performance is observed at nine out of the 12 catchments. Estimated streamflows based on soil hydraulic parameters demonstrate regionalization potential. The results indicated successful application of proposed methods which are transferable to other basins.

description: We construct a static axisymmetric wormhole from the gravitational field of two charged shells which are kept in equilibrium by their electromagnetic repulsion. For large separations the exterior tends to the Majumdar-Papapetrou spacetime of two charged particles. The interior of the wormhole is a Reissner-Nordström black hole matching to the two shells. The wormhole is traversable and connects to the same asymptotics without violation of energy conditions. However, every point in the Majumdar-Papapetrou region lies on a closed timelike curve.

description: There exists a clear physical motivation for theoretical studies of the vacuum instability related to the production of electron-positron pairs from a vacuum due to strong external electric fields. Various nonperturbative (with respect to the external fields) calculation methods were developed. Some of these methods are based on possible exact solutions of the Dirac equation. Unfortunately, there are only few cases when such solutions are known. Recently, an approximate but still nonperturbative approach to treat the vacuum instability caused by slowly varying $t$-electric potential steps (time dependent external fields that vanish as $|t|\rightarrow\infty$), which does not depend on the existence of the corresponding exact solutions, was formulated in Ref. [S. P. Gavrilov, D. M. Gitman, Phys. Rev. D \textbf{95}, 076013 (2017)]. Here, we present an approximate calculation method to treat nonperturbatively the vacuum instability in arbitrary weakly inhomogeneous $x$-electric potential steps (time-independent electric fields of a constant direction that are concentrated in restricted space areas, which means that the fields vanish as $|x|\rightarrow\infty$) in the absence of the corresponding exact solutions. Defining the weakly inhomogeneous regime in general terms, we demonstrate the universal character of the vacuum instability. This universality is associated with a large density of states excited from the vacuum by the electric field. Such a density appears in our approach as a large parameter. We derive universal representations for the total number and current density of the created particles. Relations of these representations with a locally constant field approximation for Schwinger's effective action are found.

Quantum-Classical Correspondence in Energy Space: Two Interacting Spin-Particles

description: The Hamiltonian conservative system of two interacting particles has been considered both in classical and quantum description. The quantum model has been realized using a symmetrized two-particle basis reordered in the unperturbed energy. Main attention is paid to the structure of chaotic eigenfunctions (EF) and to the local spectral density of states (LDOS). A remarkable correspondence has been found for the shapes of EF and LDOS in the energy representation, to their classical counterparts. Comparison with the Band Random Matrix theory predictions has revealed quite significant differences which are due to dynamical nature of the model. On the other hand, a partial agreement is found by inserting randomness `` ad hoc '' in the dynamical model for two-body matrix elements. This shows that, at least for small number of particles, care must be taken when classical correlations are neglected. The question of quantum localization in the energy space is discussed both for dynamical and random model.

Part I. Total Synthesis and Structural Revision of (±)-Tricholomalides A and B. Part II. Synthetic Studies towards (+)-Cortistatin A
Creators: Wang, Zhang
Publisher: name: Columbia University
Year: 2011
Subjects: Chemistry

description: The first part describes the total synthesis and structural revision of (±)-tricholomalides A and B. The synthetic strategy started from a homo-Robinson annulation, followed by a ketene-olefin [2+2] cycloaddition to introduce the lactone ring. Then a Grignard-type reaction appended the isopropenyl moiety, and the synthesis of tricholomalides A and B was achieved. During the course of synthesis, the structures of tricholomalides A and B were revised. The second part describes the synthetic studies towards (+)-cortistatin A, especially the A ring functionalization. The C3 nitrogen was introduced by azide displacement, and C2 hydroxyl was built up by Luche reduction. The challenging C1 functionalization was achieved with bromine-induced methoxymethyl deprotection, and some interesting chemistry was found in this system. The synthetic endeavor set a promising stage for the total synthesis of cortistatin A.
Part 1: Progress Toward the Total Synthesis of Platensimycin. Part 2: Aromatic Ions: Carbon-Based Nucleofuges and Chiral Cyclopropenones and Formamides

description: This thesis describes progress toward to the total synthesis of the natural product platensimycin, the development of proficient carbon nucleofuges for the Tsuji-Trost allylation, and the use of chiral cyclopropenones and formamides for the kinetic resolution of alcohols by chlorodehydration. The first chapter describes efforts in the total synthesis of platensimycin.  The synthesis attempted to use a thermal rearrangement, through a biradical intermediate, and then radical induced [3+2] cycloaddition between a vinyl cyclopropane and pendant olefin to create the core of platensimycin.  A revised strategy was employed using a palladium(0) catalyzed Heck cascade and palladium(II) catalyzed alkoxypalladation. The second chapter describes the development of a carbon-based nucleofuge.  A substituted cyclopentadienyl anion served as a competent leaving group in the Tsuji-Trost allylation.  Various substrates were examined including carbon and nitrogen nucleophiles.  The reaction mechanism with nitrogen nucleophiles is studied. The third chapter describes the synthesis of chiral cyclopropenones and their use in the kinetic resolution of alcohols by chlorodehydration.  Chiral formamides are also studied for their use in chlorodehydration.  Transition states for enantiodifferentiation are proposed.
Comparative inventory of vegetation and soils surrounding Teck Coal Ltd.'s Coal Mountain Operations

description: Coal mine reclamation has historically consisted primarily of planting agronomic species on forage areas and/or to meet biomass accrual standards; in modern day reclamation a shift is occurring towards more biodiversity driven standards. This project represents a positive step in an ecosystem based approach to developing reclamation prescriptions that follow natural succession trajectories for native plant community establishment. A comparative study was implemented to examine soil and plant community characteristics on mine spoil sites and on natural reference sites to determine what native plant species and communities may be suited to establishment on ecologically comparable mine spoil sites as a reclamation treatment. A total of 22 field plots were established: 3 on spoil and 19 on reference sites. A total of 164 plant species were inventoried including 147 native, 11 introduced, and 6 agronomic species which are likely an artefact of past reclamation efforts. Sixty-seven species were identified as having high reclamation potential and are expected to be readily propagated. The soil data suggests that the mine spoils are nutritionally similar to the soils in the reference ecosystems. Recommended treatments include establishing early successional native plant communities that are developed to follow site specific successional pathways as observed near Coal Mountain Operations in reference areas.

description: We investigate the efficiency of the recently proposed Restricted Boltzmann Machine (RBM) representation of quantum many-body states to study both the static properties and quantum spin dynamics in the two-dimensional Heisenberg model on a square lattice. For static properties we find close agreement with numerically exact Quantum Monte Carlo results in the thermodynamical limit. For dynamics and small systems, we find excellent agreement with exact diagonalization, while for systems up to N=256 spins close consistency with interacting spin-wave theory is obtained. In all cases the accuracy converges fast with the number of network parameters, giving access to much bigger systems than feasible before. This suggests great potential to investigate the quantum many-body dynamics of large scale spin systems relevant for the description of magnetic materials strongly out of equilibrium.
