description: Developing mathematical models of dynamic systems is central to many disciplines of engineering and science. Models facilitate simulations, analysis of the system's behavior, decision making and design of automatic control algorithms. Even inherently model-free control techniques such as reinforcement learning (RL) have been shown to benefit from the use of models, typically learned online. Any model construction method must address the tradeoff between the accuracy of the model and its complexity, which is difficult to strike. In this paper, we propose to employ symbolic regression (SR) to construct parsimonious process models described by analytic equations. We have equipped our method with two different state-of-the-art SR algorithms which automatically search for equations that fit the measured data: Single Node Genetic Programming (SNGP) and Multi-Gene Genetic Programming (MGGP). In addition to the standard problem formulation in the state-space domain, we show how the method can also be applied to input-output models of the NARX (nonlinear autoregressive with exogenous input) type. We present the approach on three simulated examples with up to 14-dimensional state space: an inverted pendulum, a mobile robot, and a bipedal walking robot. A comparison with deep neural networks and local linear regression shows that SR in most cases outperforms these commonly used alternative methods. We demonstrate on a real pendulum system that the analytic model found enables a RL controller to successfully perform the swing-up task, based on a model constructed from only 100 data samples.
Selection of Climate Change-Informed Design Storm Events for a Tailings Storage Facility at Red Dog Operations, Alaska, USA

description: The Global Industry Standard on Tailings Management (GISTM; Global Tailings Review, 2020) requires that climate change knowledge be incorporated to increase the climate resiliency of tailings facilities. At this time, guidance for incorporating climate change knowledge into the design and operation of tailings facilities and their appurtenant structures is limited. Due to the high degree of uncertainty in climate change modelling, additional guidance is needed to effectively and consistently incorporate climate changeinformed design criteria for tailings facilities. Red Dog Operations (RDO), located in the Northwest Arctic Borough, Alaska, USA, has observed an increasing trend in the magnitude of precipitation in the region, as well as an increase in the frequency of extreme storm events, hypothesized to be a result of climate change. To achieve GISTM conformance, RDO has undertaken steps to evaluate the design, operation, and closure criteria of its tailings storage facility (TSF) and assess how operations may be impacted by climate change through the mining lifecycle. RDO initiated assessments of climate change-informed storm event return periods and probable maximum precipitation (PMP) in the region through the year 2100. Climate change modelling is subject to a high degree of uncertainty driven by variability in possible climate and socioeconomic outcomes. In the assessment of future storm events, climate modelling produces a wide range of plausible values for precipitation magnitudes. Selecting reasonable estimates to inform TSF design, operation, and closure requires a series of decisions based on existing internal and external guidance and organizational risk tolerance. This case study implements a framework for selection of climate changeinformed storm event values for evaluation of TSF design, operation, and closure criteria. The goal of the demonstrated framework is to reduce the risk of a precipitation-induced failure to as low as reasonably practicable (ALARP) while also considering the likelihood of the storm event. The decision factors discussed in this case study include climate scenario representation, timeframe, statistical quantification metric, storm event type and duration, and estimation method.

description: Two-particle correlation functions were measured for $\rm p\overline{p}$, $\rm p\overlineΛ$, $\rm \overline{p}Λ$, and $Λ\overlineΛ$ pairs in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV and $\sqrt{s_{\rm NN}}=5.02$ TeV recorded by the ALICE detector. From a simultaneous fit to all obtained correlation functions, real and imaginary components of the scattering lengths, as well as the effective ranges, were extracted for combined $\rm p\overlineΛ$ and $\rm \overline{p}Λ$ pairs and, for the first time, for $Λ\overlineΛ$ pairs. Effective averaged scattering parameters for heavier baryon-antibaryon pairs, not measured directly, are also provided. The results reveal similarly strong interaction between measured baryon-antibaryon pairs, suggesting that they all annihilate in the same manner at the same pair relative momentum $k^{*}$. Moreover, the reported significant non-zero imaginary part and negative real part of the scattering length provide motivation for future baryon-antibaryon bound state searches.

description: BRCA1 preserves genome integrity through both homology-directed repair (HDR) and stalled fork protection (SFP). In vivo, BRCA1 exists as a heterodimer with the BARD1 tumor suppressor, and both proteins harbor a C-terminal BRCT domain with a phospho-recognition surface. Most pathogenic lesions of BRCA1 and BARD1 disrupt their respective BRCT domains, and BRCA1 BRCT phospho-recognition is required for its tumor suppression activity. Here we evaluate mice with mutations (Bard1S563F and Bard1K607A) that ablate Bard1 BRCT phospho-recognition. Although not affecting HDR, these mutations impair BRCA1/BARD1 recruitment to stalled replication forks, resulting in stalled fork degradation, chromosomal instability, and sensitivity to PARP inhibitors. However, Bard1S563F/S563F and Bard1K607A/K607A mice are not tumor-prone, indicating that ablation of SFP activity alone is insufficient for spontaneous tumor susceptibility. Nevertheless, since SFP, unlike HDR, is also impaired in Brca1/Bard1 heterozygous-mutant cells, SFP and HDR may contribute to distinct stages of tumor development in BRCA1/BARD1 mutation carriers.

description: Considerable work has been devoted to the question of how to best parameterize the properties of dark energy, in particular its equation of state w. We argue that, in the absence of a compelling model for dark energy, the parameterizations of functions about which we have no prior knowledge, such as w(z), should be determined by the data rather than by our ingrained beliefs or familiar series expansions. We find the complete basis of orthonormal eigenfunctions in which the principal components (weights of w(z)) that are determined most accurately are separated from those determined most poorly. Furthermore, we show that keeping a few of the best-measured modes can be an effective way of obtaining information about w(z).

The Baroque Effect: Architecture and Art History in Berlin, 1886-1900
Creators: Narath, Albert
Publisher: name: Columbia University
Year: 2011
Subjects: Art

description: This dissertation explores the rich interplay between architecture and art historical research that emerged in Germany in the final decades of the nineteenth century through the rediscovery of the Baroque. The close connection during these years between the establishment of the Baroque as an independent architectural style within the young field of Kunstwissenschaft, the burgeoning interest in Baroque space and the mechanics of perception in psychological aesthetics, and the appearance of the Baroque in many of the most important architectural projects of the late nineteenth century made the style a flashpoint for far-reaching debates concerning the roles of art history and architecture in a period marked by profound transformations. Focusing on the reception of the Baroque in Berlin, this dissertation examines the important role of the style in attempts by architects to reexamine their discipline in the context of historicism, the unprecedented growth of the metropolis, and the complex and often conflicting array of regional and national conceptions of identity that accompanied the political development of the German Empire. Through a series of case studies documenting the remarkable interplay of art history and architectural practice in Berlin from the mid-1880's to the turn of the twentieth century, the dissertation traces the emergence of the "NeuBarock" ("New Baroque").

description: This paper examines the relative size of the effects of New Zealand monetary policy and macroeconomic data surprises on the spot exchange rate, 2 and 5 year swap rate differentials, and the synthetic forward exchange rate schedule. We find that the spot exchange rate and 5 year swap rates respond by a similar magnitude to monetary surprises, implying there is little response of the forward exchange rate to this type of news. In contrast, the spot exchange rate responds by nearly three times as much as 5 year interest rates to CPI and GDP surprises, implying that forward rates appreciate to higher than expected CPI or GDP news. This is in contrast to standard theoretical models and US evidence. Lastly, we show that exchange rates but not interest rates respond to current account news. The implications of these results for monetary policy are considered.

A valid subspecies, Tenthredo (Tenthredo) jakowlewi centrorufa (Mocsáry, 1909).
TYPES. Allantus centrorufus Mocsáry, 1909: 21. Syntypes Ƥ 3, “Turkestania: Saty-Ashu”. Lectotype 3, hereby designated (Fig. 7). Type locality: “Turkestan”, “Saty-Ashu” [=? Kyrgyzstan, Alatau: Saty, River Asu].
DISCUSSION. In the collection of the HNHM two syntypes (Ƥ 3) were found. As the female no longer has antennae, the male is hereby selected as lectotype (Fig. 7) (Ƥ paralectotype, same data as the lectotype). The status of the taxon is still under discussion. In agreement with Zhelochovtsev (1976), Taeger (1992) treated it as a subspecies of T. jakowlewi (Jakowlew, 1891) from Tian Shan, whereas Lacourt (1999) considered centrorufus without further explanation as a synonym of this species.

description: This paper studies clustering for possibly high dimensional data (e.g. images, time series, gene expression data, and many other settings), and rephrase it as low rank matrix estimation in the PAC-Bayesian framework. Our approach leverages the well known Burer-Monteiro factorisation strategy from large scale optimisation, in the context of low rank estimation. Moreover, our Burer-Monteiro factors are shown to lie on a Stiefel manifold. We propose a new generalized Bayesian estimator for this problem and prove novel prediction bounds for clustering. We also devise a componentwise Langevin sampler on the Stiefel manifold to compute this estimator.

Certain linear combinations of them satisfy the anti - de Sitter algebra so(2,2) in either ADM or holonomy variables. Quantisation is straightforward in terms of the holonomy parameters. On inclusion of the Hamiltonian three new global constants are derived and the quantum algebra extends to that of the conformal algebra so(2,3). The modular group appears as a discrete subgroup of the conformal group. Its quantum action is generated by these conserved quantities.

The manifolds are related to the compactified level sets of the generalized (nonperiodic) Toda lattice equations defined on the semisimple Lie algebras. We then give a cellular decomposition and the associated chain complex of the manifold by introducing colored Dynkin diagrams which parametrize the cells in the decomposition. We also discuss the Morse chain complex of the manifold.

description: In this work, we present a novel distributed method for constructing an occupancy grid map of an unknown environment using a swarm of robots with global localization capabilities and limited inter-robot communication. The robots explore the domain by performing Levy walks in which their headings are defined by maximizing the mutual information between the robot's estimate of its environment in the form of an occupancy grid map and the distance measurements that it is likely to obtain when it moves in that direction. Each robot is equipped with laser range sensors, and it builds its occupancy grid map by repeatedly combining its own distance measurements with map information that is broadcast by neighboring robots. Using results on average consensus over time-varying graph topologies, we prove that all robots' maps will eventually converge to the actual map of the environment. In addition, we demonstrate that a technique based on topological data analysis, developed in our previous work for generating topological maps, can be readily extended for adaptive thresholding of occupancy grid maps. We validate the effectiveness of our distributed exploration and mapping strategy through a series of 2D simulations and multi-robot experiments.

Trade associations

description: This dissertation traces the formation and development of the Hollywood film industry’s trade association between 1922 and 1945. For nearly three decades, an oligopoly of vertically integrated production-distribution firms dominated the American film industry. Throughout this period these Hollywood majors relied on a powerful trade organization, the Motion Picture Producers and Distributors Association (MPPDA) to coordinate cooperative programs aimed at maintaining this form of industrial organization. In the existing literature, the operations of the MPPDA are taken as coincident with the economic imperatives of the major firms who were its sponsors, but this trade association often struggled to coordinate a membership that viewed its efforts with skepticism and outright resistance. Negotiating the competing member interests and reconciling their divergent views of cooperative action were core functions of the MPPDA that have been largely overlooked. This dissertation asks how the MPPDA created consensus around cooperative actions, what prevented it doing so by the early 1940s, and what the consequences of this failure were for the industry it represented. In order to account for the internal activities of this trade association and their consequences on the development of the film industry, this dissertation integrates a primary archival methodology with conceptual tools from economic sociology and organizational studies. Part One analyzes the trade association’s structure, resources, and activities in relation to changing economic and political contexts between 1922 and 1938. Part Two offers three case studies of the association’s cooperative actions during the 1940s—lobbying, public relations, and intellectual-property registration—in order to demonstrate how changes in the broader political environment, the workforce at member firms, and the production sector of the film industry exacerbated tensions among stakeholders in the MPPDA and undermined its ability to maintain the support of the oligopoly. This dissertation highlights the value in investigating the collision of various stakeholders, interests, and agendas within seemingly unified institutions. The use of overlooked archival resources reveals new sources for primary research, and the use of theoretical frameworks from fields like economic sociology suggests approaches to understanding aspects of institutions that have been largely neglected in film and media history.
The Battle over Critical Race Curriculum: U.S. States and the Political Struggle over Ethnic Studies in K-12 Schools in the 21st Century

description: This dissertation explores the racial politics of the U.S. through an examination of political contention over the inclusion of ethnic studies in K-12 public schools. Black, Indigenous, Chicanx/Latinx, and Asian/Pacific Islander Americans have indelibly shaped the political, economic, and social contours of the U.S. from its founding to present. However, the fullness of their experiences in and contributions to the nation remain woefully inadequate in K-12 U.S. history/social studies curricula (Brown & Brown, 2010; Journell, 2009; Ladson-Billings, 2003; Loewen, 1996; Reddick, 1934; Woodson, 1933; Woodson & Wesley, 1922). To address this curricular gap, a wave of 21st century activism is demanding that K-12 schools teach ethnic studies, curricula that centers and examines the history of race, racism, and the contributions of people of color in the U.S. Contemporary state policies requiring the inclusion of ethnic studies in K-12 schools are far more progressive (and contentious) than aligned education reforms of previous decades, which were overwhelmingly school district policies focused on offering an optional ethnic studies elective. Drawing on archival, media, and interview data from three states (Arizona, California and Oregon) which recently decided on including ethnic studies in K-12 schools, I explore how race shaped the state policy processes and outcomes. While Arizona banned ethnic studies, Oregon adopted an ethnic studies requirement, and California’s ethnic studies requirement was vetoed by its governor. I argue that advocacy for the inclusion of ethnic studies which employs critical race conscious frames, mitigates intra-partisan conflict, and engages intersectional mobilization is most strongly positioned to advance such systemic, state-level reform. By examining the racial political dynamics of systemic policy change, this dissertation intervenes in political sociology and race scholarship in education. The findings can, moreover, help advocates of the full inclusion of ethnic studies in K-12 schools navigate the path toward systemic reform.

description: Quantum spin Hall (QSH) insulators are materials that feature an insulating bulk and host edge states protected by time-reversal symmetry. The helical locking of spin and momentum in these states suppresses backscattering of charge carriers, promising applications from low-power electronics to quantum computing. A major challenge for applications is the identification of large gap QSH materials, which would enable room temperature dissipationless transport in their edge states. Here we show that the layered mineral jacutingaite (Pt$_2$HgSe$_3$) is a candidate QSH material, realizing the long sought after the Kane-Mele insulator. Using scanning tunneling microscopy, we measure a band gap of 110 meV, above room temperature, and identify the hallmark edge states. By calculating the $\mathbb{Z}_2$ invariant, we confirm the topological nature of the gap. Being a layered mineral, it is stable in air and can be thinned down to a few atomic layers by mechanical exfoliation. Furthermore, we demonstrate that it can be integrated into heterostructures with other two-dimensional materials. This adds a topological insulator to the 2D quantum material library, greatly expanding the possibilities for tuning 2D electron systems using stacks of layered materials.

description: This dissertation examines the popular politics of the anticolonial struggle in Algiers from the perspective of people who participated in the Algerian Revolution at a grassroots level. It is largely the product of interviews conducted with 30 women and men who participated in the revolution in and around Algiers. Their participation in the struggle took diverse forms, including armed combat, material or logistical support to those fighting, participating in strikes or protests, and so on. In examining Algerians' anticolonial struggle 'from below,' I have sought to illuminate different and more plural perspectives of this period of history. In presenting this new material, I put forward a number of critiques on the existing historiography of the Algerian Revolution. My goal has been not only to include those who have been excluded from larger narratives in order to fold them into the political history of the revolution, but to demonstrate how these perspectives challenge those narratives. Finally, I have taken the experiences and perspectives of these Algerians to be a legitimate and productive vantage point from which to reflect on larger theoretical questions of popular politics and revolutions in the colonized world. These include questions about revolution, the diverse political imaginaries of what constitutes liberation and freedom, the means that can justly be used to attain such ends, the blurry lines between resistance and collaboration, the relationship between avant-garde parties and the masses that lend them support, and the different iterations of Islamic politics in modernity.
Charm and bottom quark production in photon-nucleon and photon-photon collisions

description: I discuss mechanisms of heavy quark production in (real) photon-nucleon and (real) photon - (real) photon collisions. In particular, I focuse on application of the Saturation Model. In addition to the main dipole-nucleon or dipole-dipole contribution included in recent analyses, I propose how to calculate within the same formalism the hadronic single-resolved contribution to heavy quark production. At high photon-photon energies this yields a sizeable correction of about 30-40 % for inclusive charm production and 15-20 % for bottom production.

The Battle before the War: War In Europe and the 1940 U.S. Senate Elections

description: In this thesis, I investigate the foreign policy rhetoric used by candidates in two elections to the United States Senate in 1940. First, by examining the history of the 76th Congress on legislation related to the war in Europe, I develop a political framework for understanding the rhetorical developments that occurred between the outbreak of war and the beginning of the electoral campaign. I then apply this framework to the Senate elections themselves. From this investigation, I conclude that candidates who could be broadly identified as “internationalist,” by the time of the election, had adopted a position of preparedness — the notion that the United States should be socially, economically, and militarily prepared to enter the war in Europe, although entry into the war was not the goal. Candidates who believed in some degree of isolationism, in contrast, framed their position as pro-democratic, attempting to make President Roosevelt’s decision to seek a third term evidence of a sinister, anti-democratic plot. These rhetorical pivots demonstrate what politicians perceived as an American public fraught with contradictory impulses — a fear of both being caught up in foreign entitlements and a fear of tyrannical government occupying most of Europe.

description: We describe and analyze a numerical algorithm for computing the homology (Betti numbers and torsion coefficients) of semialgebraic sets given by Boolean formulas. The algorithm works in weak exponential time. This means that outside a subset of data having exponentially small measure, the cost of the algorithm is single exponential in the size of the data. This extends the previous work of the authors in arXiv:1807.06435 to arbitrary semialgebraic sets. All previous algorithms proposed for this problem have doubly exponential complexity.

description: Toy models for the Hubble rate or the scalar field potential have been used to analyze the amplification of scalar perturbations through a smooth transition from inflation to the radiation era. We use a Hubble rate that arises consistently from a decaying vacuum cosmology, which evolves smoothly from nearly de Sitter inflation to radiation domination. We find exact solutions for super-horizon perturbations (scalar and tensor), and for sub-horizon perturbations in the vacuum- and radiation-dominated eras. The standard conserved quantity for super-horizon scalar perturbations is exactly constant for growing modes, and zero for the decaying modes.

description: We prove that, given a constant $K> 2$ and a bounded linear operator $T$ from a JB$^*$-triple $E$ into a complex Hilbert space $H$, there exists a norm-one functional $ψ\in E^*$ satisfying $$\|T(x)\| \leq K \, \|T\| \, \|x\|_ψ,$$ for all $x\in E$. Applying this result we show that, given $G > 8 (1+2\sqrt{3})$ and a bounded bilinear form $V$ on the Cartesian product of two JB$^*$-triples $E$ and $B$, there exist norm-one functionals $φ\in E^{*}$ and $ψ\in B^{*}$ satisfying $$|V(x,y)| \leq G \ \|V\| \, \|x\|_φ \, \|y\|_ψ$$ for all $(x,y)\in E \times B$. These results prove a conjecture pursued during almost twenty years.

description: Enterotoxigenic Escherichia coli (ETEC) is a diarrhoeal pathogen associated with severe morbidity and mortality among young children in developing countries. At present, there is no vaccine for ETEC. One candidate vaccine antigen, EtpA, is a conserved secreted adhesin that presumably binds to the tips of the E. coli flagellum to link ETEC to host intestinal glycans. EtpA is exported through a Gram-negative, two-partner secretion (TPS) system (type Vb) comprised of the secreted EtpA passenger (TpsA) protein and EtpB (TpsB) a transporter integrated into the outer bacterial membrane. TpsA proteins share a conserved, N-terminal domain followed by an extensive C-terminal domain with divergent sequence repeats. Three constructs of EtpA were prepared and analysed respectively including residues 67 to 447 (EtpA67-447), residues 1 to 606 (EtpA1-606) and residues 67-930 (EtpA67-930). The crystal structure of EtpA67-447 solved at 1.76 Å resolution revealed a right-handed parallel β-helix with two extra-helical hairpins and an N-terminal β-strand cap. Analyses by circular dichroism spectroscopy confirmed the β-helical fold and indicated high resistance to chemical and thermal denaturation as well as rapid refolding. A theoretical model of full-length EtpA by AlphaFold largely concurs with the crystal structure adding a long β-helical C-terminal domain after an interdomain kink. We propose that robust folding of the TPS domain upon secretion provides a template to extend the N-terminal β-helix into the C-terminal domains of TpsA proteins. Unexpectedly, size exclusion chromatography and molecular pulldown assays with the N-terminal domain of EtpA failed to show any interaction with flagellin implying that other factors may be involved.

The Benefits and Drawbacks of Mainstreaming Students with Autism

Publisher: name: Columbia University
Year: 2012
Subjects: subject: Psychology
subject: FOS: Psychology
subject: Special education

description: The issue of mainstreaming students with autism into general education settings has become a major source of controversy. Many educators view mainstreaming as beneficial for students with autism, as it allows them access to neurotypical peers who can serve as role models for acceptable social behavior and it teaches their neurotypical peers to be receptive to those who are different from them. In contrast, others believe that mainstreaming will cause students with autism to be socially excluded given their atypical behavior and they will lose out on the necessary individualized instruction they would receive in a special education classroom. The benefits and drawbacks to inclusion will be discussed in this paper. The paper will also address the ethical considerations regarding the role of regular education teachers in accommodating students with autism in general education settings and proposed classroom modifications. The paper will conclude with a discussion of the need for further research.
N-alkynylations of substituted pyrroles with 1-bromo-1-alkynes and C-alkylations and C-alkenylations of cyclic 1,2-diketones

description: Nitrogen-substituted alkynes are a unique class of compounds that have found general use in organic synthesis. The catalytic synthesis of N-substituted alkynes offers a rapid and step-efficient approach for accessing this structural motif. To better understand the synthesis and reactivity profile of N-alkynyl pyrroles, a study of the Cu-catalyzed coupling of pyrroles with 1-bromoalkynes was conducted and the scope uncovered. Subsequently, N-alkynyl pyrroles were applied to the synthesis of pyrrole[2,1-c]oxazin-1-ones and the formal total synthesis of the natural product peramine. Additionally, an N-alkynyl pyrrole was applied toward the synthesis of the pyrrole spiroketal alkaloid shensongine A. The α-alkylation of ketones is an indispensible C-C bond forming process to organic chemists. This process generally involves the formation of an enolate and subsequent alkylation with an electrophile. While very efficient, this series of steps generates a significant amount of waste that is often not on the radar of the typical chemist. Recent work has begun to address this issue resulting in several new “green” α-alkylation procedures. In an effort to better understand the potential application of a C-H activation procedure towards the “green” alkylation of ketones a study of the C-H activation and subsequent alkylation and alkenylation of cyclic 1,2-diketones was conducted.
