description: The recent detection of a 3-hr X-ray flare by the Chandra Observatory has raised the possibility of enhanced emission over a broad range of wavelengths from Sgr A*, the suspected 2.6 x 10^6 solar mass black hole at the Galactic Center, during a flaring event. We have, therefore, reconstructed 3-hr data sets from 2 micron speckle and adaptive optics images (theta_core = 50 - 100 mas) obtained with the W. M. Keck 10-m telescopes between 1995 and 2001. In 25 separate observations, no evidence of any significant excess emission associated with Sgr A* was detected. The lowest of our detection limits gives an observed limit for the quiescent state of Sgr A* of 0.09+/-0.005 mJy, or, equivalently, a dereddened value of 2.0+/-0.1 mJy, which is a factor of 2 lower than the best previously published quiescent value. Under the assumption that there are random 3-hr flares producing both enhanced X-ray and near-infrared emission, our highest limit constrains the variable state of Sgr A* to <0.8 mJy (observed) or 19 mJy (dereddened). These results suggest that the model favored by Markoff et al. (2001), in which the flare is produced through local heating of relativistic particles surrounding Sgr A* (e.g., a sudden magnetic reconnection event), is unlikely, because it predicts peak 2 micron emission of 300 mJy, well above our detection limit.

description: Deep neural networks (DNN) are known to be vulnerable to adversarial attacks. Numerous efforts either try to patch weaknesses in trained models, or try to make it difficult or costly to compute adversarial examples that exploit them. In our work, we explore a new "honeypot" approach to protect DNN models. We intentionally inject trapdoors, honeypot weaknesses in the classification manifold that attract attackers searching for adversarial examples. Attackers' optimization algorithms gravitate towards trapdoors, leading them to produce attacks similar to trapdoors in the feature space. Our defense then identifies attacks by comparing neuron activation signatures of inputs to those of trapdoors. In this paper, we introduce trapdoors and describe an implementation of a trapdoor-enabled defense. First, we analytically prove that trapdoors shape the computation of adversarial attacks so that attack inputs will have feature representations very similar to those of trapdoors. Second, we experimentally show that trapdoor-protected models can detect, with high accuracy, adversarial examples generated by state-of-the-art attacks (PGD, optimization-based CW, Elastic Net, BPDA), with negligible impact on normal classification. These results generalize across classification domains, including image, facial, and traffic-sign recognition. We also present significant results measuring trapdoors' robustness against customized adaptive attacks (countermeasures).

description: The hydrogen absorption behavior of organic-compound clathrate hydrates was investigated using five kinds of organic compounds as well as tetrahydrofuran (THF). These hydrates were pressurized by hydrogen, and Raman analysis, the determination of the amount of hydrogen and calorimetric measurement were carried out. The Raman results show that the samples investigated in this work formed binary clathrate hydrate of hydrogen and each organic compound. The organic-compound clathrate hydrates presented similar performances to that of THF clathrate hydrate regarding hydrogen absorption and heat of dissociation. These results suggested that the organic compounds investigated in this work may become alternatives to THF.

Essays on Misallocation and Firm Regulations

description: This dissertation is a collection of three essays on misallocation and firm regulations. The first chapter investigates how size-dependent firm regulation policies can mitigate misallocation. The second chapter uses the same framework as the first to explore the intuition of a theoretically more subtle concept of misallocation. The third chapter analyzes a more specific firm regulation that targets at financial dealers.
      In chapter 1, I study the welfare implications of size-dependent firm regulation policies (SDPs) in the presence of entrepreneurial risks. Although SDP has been considered a source of misallocation, I show that, once entrepreneurial risks are taken into account, SDP might improve efficiency. Quantitatively, I show that, based on French data, removing the SDP leads to output and welfare loss by 1.5% and 1.3%, respectively, in opposition to the output gain reported by the previous literature that abstracts from risks. Qualitatively, I solve an optimal non-linear SDP problem and show that the observed SDP shares certain features with the optimal SDP. The analysis uncovers a novel trade-off between the inefficiencies of the intensive and extensive margins. In extension, it is shown that (1) whether SDPs improve efficiency depends on the level of financial development and (2) capital accumulation and consumption-smoothing motive further justify SDPs.
      In chapter 2, which is a joint work with Misaki Matsumura, we use the same competitive entrepreneurship model to investigate the economic intuition of constrained inefficiency caused by uninsurable risks. Although the constrained efficiency of various models has been studied in the literature, the economic intuition of why the constrained planner's intervention yields an improvement is usually not available. The competitive entrepreneurship model is particularly suitable for seeing the logic of constrained inefficiency since the structure of the market equilibrium is characterized by the indifference condition instead of the marginal condition. To illustrate this point, we contrast the competitive entrepreneurship model with simple versions of the Aiyagari model and the Krebs model.
      In chapter 3, which is also a joint work with Misaki Matsumura, we build a general equilibrium model to analyze the impact of the Volcker rule, a dealer regulation imposed after the financial crisis, on price quality (informativeness and volatility) and its implications on the welfare of market participants. We argue that although price informativeness, volatility and the dealer's profitability all deteriorate, against conventional wisdom, other market participants are better off due to the dealer's risk-shifting motive. A static model is used to clarify the main intuition, and the robustness of the welfare results as well as the fragility of the conventional wisdom about price quality are discussed by incorporating dynamics and endogenizing information acquisition.

description: The topological pressure introduced by Ruelle and similar quantities describe dynamical multifractal properties of dynamical systems. These are important characteristics of mesoscopic systems in the classical regime. Original definition of these quantities are based on the symbolic description of the dynamics. It is hard or impossible to find symbolic description and generating partition to a general dynamical system, therefore these quantities are often not accessible for further studies. Here we present a new method by which the symbolic description can be omitted. We apply the method for a mixing and an intermittent system.

We establish a strong law of large numbers, a bounded law of the iterated logarithms and a central limit theorem under a dependence condition. The main ingredients for the proof are an approximation by U-statistics whose data is a functional of $\ell$ i.i.d. random variables and an analogue of the Hoeffding's decomposition for U-statistics of this type.

description: Nigeria’s peasant cattle production is based in its semi-arid north. The area’s aridity becomes a major problem to cattle in the dry season. Herds are protected by bringing them down to the southern parts that are usually wetter at such times. Presence of tsetse fly in the south, particularly in the rainy season precludes sustained all year round grazing in the south. This sets the stage for migration back to the north at the onset of rains in the south. A number of social events has been observed that suggest possible change in the way this transhumance is conducted. The Fulani herders from northern Nigeria appear to be staying longer in the south. They are also turning sedentary and pressurizing local resources and farmlands more intensely leading to violent and deadly conflicts with their local farming hosts in the south. On the other hand, some southern farmers now have successful cattle production enterprises based on the tsetse fly prone Fulani cattle breeds. This study seeks to find out if these trends indicate a negatively changed northern environment that is turning more hostile to peasant cattle production and promoting greater pressures on the south. It also seeks to finds out if the trends show a positive change in the environment of southern Nigeria in terms of a changed tsetse fly habitat and decline in its populations. The study is approached through surveys involving the Fulani herdsmen operating in southern Nigeria and their host communities. Results indicate a paradigm shift in understanding of ethnic clashes in Nigeria in the light of environmental change; some positive effects of environmental change; that positive environmental change may lead to negative social impacts. They also show that internal migration in Nigeria is largely environment dependent.

Essays on Microfoundations of Peacebuilding in War-Torn Societies: Hypotheses and Evidence from a Field Experiment in Rural Liberia.

Subjects: subject: Political participation
subject: Democracy

subject: FOS: Political science

description: Can international peacebuilding efforts in war-torn societies have positive influence on democratic outcomes at the grassroots level? Does any such influence occur through military channels (e.g., security provision) or civilian channels (e.g., democratic education)? How do different local settings respond to various activities carried out by outside interveners? A key objective of contemporary peacebuilding interventions is to transform war-torn societies into stable, liberal democratic polities, based on the premise that democracy is the best way to achieve stable and self-sustaining peace because democracies are more respectful toward their citizens and peaceful toward their neighbors (Barnett 2006). Toward this end, in addition to providing security, international interveners typically undertake a wide range of activities to democratize existing structures both at the macro-level and micro-level. There are important variations in local settings in which peacebuilding activities tend to be carried out. Surprisingly, there have been few systematic efforts to investigate whether and how differences in local settings shape the performance and outcomes of peacebuilding interventions, in particular to ascertain the effectiveness of efforts to promote democratic norms and liberal values at the grassroots level. This dissertation attempts to fill this gap--theoretically and empirically. It draws on social science theories to outline specific hypotheses about when and how various activities carried out by outside actors may be effective in promoting liberal democratic outcomes in different local settings. These hypotheses are tested empirically through a nine-month field experiment carried out in 142 villages in postwar Liberia, in partnership with a United Nations peacekeeping mission and two local civil society organizations. Empirical findings reveal that the effects of outside interventions on democratic outcomes at the grassroots level critically depend on context types, but the saliency of local contexts is more pronounced for some outcome areas (e.g., political participation) than others (e.g., social cohesion). Theoretical and policy implications of these results will be discussed.

description: This dissertation analyzes problems related to matching in general networks and decision under uncertainty. Chapter 1 introduces the framework of convex matching games. Chapter 2 discusses three distinct applications of the framework. Chapter 3 develops a new test of choice models with expected utility.
      In Chapter 1, I use Scarf's lemma to show that given a convexity structure that I introduce, the core of a matching game is always nonempty, and the framework I introduce can accommodate general contracting networks, multilateral contracts, and complementary preferences.
      In Chapter 2, I provide three applications to show how the convexity structure is satisfied in different contexts by different assumptions. In the first application, I show that in large economies, the convexity structure is satisfied if the set of participants in each contract is small compared to the overall economy. The second application considers finite economies, and I show that the convexity structure is satisfied if all agents have convex, but not necessarily substitutable, preferences. The third application considers a large-firm, many-to-one matching market with peer preferences, and I show that the convexity structure is satisfied under convexity of preferences and a competition aversion restriction on workers' preferences over colleagues.
      In Chapter 3, I show that some form of cyclic choice pattern across distinct information scenarios should be regarded as inconsistent with a utility function that is linear in beliefs.

description: We suggest that the Virgo Overdensity (VOD) of stars in the stellar halo is the result of a radial dwarf galaxy merger that we call the Virgo Radial Merger. Because the dwarf galaxy passed very near to the Galactic center, the debris has a large range of energies but nearly zero $L_z$ angular momentum. The debris appears to extend from 5 to 50 kpc from the Sun in the Virgo region. We connect different parts of this merger debris to the Perpendicular and Parallel Streams (the Virgo Stellar Stream is associated with either or both of these streams), the Hercules-Aquila Cloud (HAC), and possibly the Eridanus Phoenix Overdensity (EriPhe). This radial merger can explain the majority of the observed moving groups of RR Lyrae and blue horizontal branch stars that have previously been identified in Virgo. This merger also produces debris in the Solar neighborhood similar to that identified as the Gaia-Enceladus or it Gaia-sausage merger. Orbits are provided for components of the Virgo Radial Merger progenitor and for debris that appears to be related to the Cocytos Stream, which was also recovered in the Virgo region.

description: The $X^{s,b}$ spaces, as used by Beals, Bourgain, Kenig-Ponce-Vega, Klainerman-Machedon and others, are fundamental tools to study the low-regularity behaviour of non-linear dispersive equations. It is of particular interest to obtain bilinear or multilinear estimates involving these spaces. By Plancherel's theorem and duality, these estimates reduce to estimating a weighted convolution integral in terms of the $L^2$ norms of the component functions. In this paper we systematically study weighted convolution estimates on $L^2$. As a consequence we obtain sharp bilinear estimates for the KdV, wave, and Schrödinger $X^{s,b}$ spaces.

description: Convection-dominated accretion flow (CDAF) is a promising model to explain underluminous accreting black holes in X-ray binaries and galactic nuclei. I discuss effects of angular momentum transport in viscous hydrodynamical and MHD CDAFs. In hydrodynamical CDAFs, convection transports angular momentum inward, and this together with outward convection transport of thermal energy determine the radial structure of the flow. In MHD CDAFs, convection can transport angular momentum either inward or outward, depending on properties of turbulence in rotating magnetized plasma, which are not fully understood yet. Direction of convection angular momentum transport can affect the law of rotation of MHD CDAFs.

description: The two-time distribution gives the limiting joint distribution of the heights at two different times of a local 1D random growth model in the curved geometry. This distribution has been computed in a specific model but is expected to be universal in the KPZ universality class. Its marginals are the GUE Tracy-Widom distribution. In this paper we study two limits of the two-time distribution. The first, is the limit of long time separation when the quotient of the two times goes to infinity, and the second, is the short time limit when the quotient goes to zero.

On Super RS algebra and Drinfeld Realization of Quantum Affine Superalgebras
Creators: name: Gould, Mark D.

Subjects: subject: Quantum Algebra (math.QA)

description: We describe the realization of the super Reshetikhin-Semenov-Tian-Shansky (RS) algebra in quantum affine superalgebras, thus generalizing the approach of Frenkel-Reshetikhin to the supersymmetric (and twisted) case. The algebraic homomorphism between the super RS algebra and the Drinfeld current realization of quantum affine superalgebras is established by using the Gauss decomposition technique of Ding-Frenkel. As an application, we obtain Drinfeld realization of quantum affine superalgebra $U_q[osp(1|2)^{(1)}]$ and its degeneration -- central extended super Yangian double $DY_\hbar[osp(1|2)^{(1)}]$.

description: I describe a method, particularly suitable to implementation by computer algebra, for the derivation of low-dimensional models of dynamical systems. The method is systematic and is based upon centre manifold theory. Computer code for the algorithm is relatively simple, robust and flexible. The method is applied to two examples: one a straightforward pitchfork bifurcation, and one being the dynamics of thin fluid films.

description: A quantum spin system is discussed, where a heat flow between infinite reservoirs takes place in a finite region. A time dependent force may also be acting. Our analysis is based on a simple technical assumption concerning the time evolution of infinite quantum spin systems. This assumption, physically natural but currently proved for few specific systems only, says that quantum information diffuses in space-time in such a way that the time integral of the commutator of local observables converges: $\int_{-\infty}^0dt ||[B,α^tA]||

description: Long-range interacting systems are omnipresent in nature. We investigate here the collective dynamical behavior in a long-range interacting system consisting of coupled Stuart-Landau limit cycle oscillators. In particular, we analyze the impact of a repulsive coupling along with symmetry breaking coupling. We report that the addition of repulsive coupling of sufficient strength can induce a swing of the synchronized state which will start disappearing with an increasing disorder as a function of the repulsive coupling. We also deduce analytical stability conditions for the oscillatory states including synchronized state, solitary state, two-cluster state as well as oscillation death state. Finally, we have also analyzed the effect of power-law exponent on the observed dynamical states.

description: We show that for a large class of contact 3-manifolds the groups of Vassiliev invariants of Legendrian and of framed knots are canonically isomorphic. As a corollary, we obtain that the group of finite order Arnold's $J^+$-type invariants of wave fronts on a surface $F$ is isomorphic to the group of Vassiliev invariants of framed knots in the spherical cotangent bundle $ST^*F$ of $F$. On the other hand we construct the first examples of contact manifolds for which Vassiliev invariants of Legendrian knots can distinguish Legendrian knots that realize isotopic framed knots and are homotopic as Legendrian immersions.

Essays on Network Formation and Attention
Creators: Neligh, Nate Leigh
Publisher: name: Columbia University
Year: 2018
Subjects: Economics
Attention
Decision making

description: This dissertation tackles two important developing topics in economics: network formation and the allocation of attention. First, it examine the idea that the timing of entry into the network is a crucial determinant of a node’s final centrality. We propose a model of strategic network growth which makes novel predictions about the forward-looking behaviors of players. In particular, the model predicts that agents entering the network at specific times will become central “vie for dominance”. In a laboratory experiment, we find that players do exhibit “vying for dominance” behavior, but do not always do so at the predicted critical times. A model of heterogeneous risk aversion best fits the observed deviations from initial predictions. Timing determines whether players have the opportunity to become attempt to become dominant, but individual characteristics determine whether players exploit that opportunity. This dissertation also examines models of rational inattention, in which decision-makers rationally evaluate the trade-off between the costs and the benefits of information acquisition. We provide results on recovering the implicit attention cost function by looking at the relationship between incentives and performance. We conduct laboratory experiments consisting of simple perceptual tasks with fine-grained variation in the level of potential rewards. We find that most subjects exhibit monotonicity in performance with respect to potential rewards, and there is mixed evidence on continuity and convexity of costs. We also perform a model selection exercise and find that subjects’ behavior is generally most consistent with a small but diverse subset of cost functions commonly assumed in the literature.

Essays on Multidimensional Private Information in the Consumer Credit Market
Creators: Kim, MeeRoo
Publisher: name: Columbia University
Year: 2018
Subjects: Economics
Consumer credit
Information behavior

description: In these essays, I study how multidimensional private information causes advantageous selection in a highly concentrated consumer credit market. All three chapters are tightly correlated with each other. I first carefully investigate conditional correlations between choices of a loan type, private default risks, and an additional private information on consumption smoothing motives. I find that their conditional correlations appear consistent with advantageous selection being driven by unobserved heterogeneity in consumption smoothing motives. Then I document how moral hazard links two dimensions of private information: consumption smoothing motives and default risks. By separately identifying moral hazard from adverse selection, I show that consumers with stronger consumption smoothing motives exert more effort to prevent default, generating an endogenous negative association between consumption smoothing motives and default risks. Finally, using a dynamic model of loan type choices and following outcome of default, I recover the joint distribution of bi-dimensional unobserved heterogeneity. This structural estimation also suggests a new way to estimate the inter-temporal elasticity of substitution that represents heterogeneous consumption smoothing motives. As well as being consistent with the results of previous chapters, the results of the structural estimation reveal a strong and positive correlation between inter-temporal elasticity of substitution and default risks.

description: UAV systems in biochemistry is an emerging field of research that offers to advance optimal medical care through improved timeliness in diagnosis. This thesis reviews the relevant literature on liquid characteristics and current UAV technologies. It then proceeds to study drop behaviour on superhydrophobic surfaces with the objective of creating a practicable UAV system able to conduct biochemical applications. While this objective was not fully achieved, it revealed important insights relevant in the use of vials and capillary tubes. Through the use of manoeuvres and modification of elements, bio-chemical processes such as mixing and centrifugation were attained.

description: Two newly identified magnetic cataclysmic variables discovered in the Sloan Digital Sky Survey (SDSS), SDSSJ155331.12+551614.5 and SDSSJ132411.57+032050.5, have spectra showing highly prominent, narrow, strongly polarized cyclotron humps with amplitudes that vary on orbital periods of 4.39 and 2.6 hrs, respectively. In the former, the spacing of the humps indicates the 3rd and 4th harmonics in a magnetic field of ~60 MG. The narrowness of the cyclotron features and the lack of strong emission lines imply very low temperature plasmas and very low accretion rates, so that the accreting area is heated by particle collisions rather than accretion shocks. The detection of rare systems like these exemplifies the ability of the SDSS to find the lowest accretion rate close binaries.
