Communication of technical information

description: The purpose of this study is to explore how social media can be used as a data source and to engage citizens in urban planning and governance process. Given the rise of mobile technologies and the extensive use of social media networks in cities in the global south, electronic participation (e-participation) has become a mechanism for constant interaction between residents and government officials and is a method to collect unique information from the public. However, it is still not clear how reliable and accurate social media data can be for urban planning. Through a case study analysis of Sucre Municipality in Caracas, the capital city of Venezuela, this research used a social media platform, Twitter, to examine the content collected through the exchange between the public and the Mayor of Sucre over three months. The tweets were examined regarding time, location, theme and content and comparisons were made with official documents and news articles to evaluate accuracy and relevance of the data. People engage more with the Mayor than the institution and the amount of tweets regarding the city overpass political or personal ones. Slum areas use social media as an advocacy platform to rise their concerns regarding water shortage and waste management irregularities. Urban and formal areas use tweets as primary mechanism to communicate crimes and irregularities in the physical state of streets. Two tweet-sourced interactive maps were developed in web mapping platform to visualize the content of the tweets. Recommendations were made to help municipalities and planners to incorporate efficiently and critically social media as a new participatory tool for planning and governance.

Two Approaches to Non-Zero-Sum Stochastic Differential Games of Control and Stopping
Creators: Li, Qinghua
Publisher: name: Columbia University
Year: 2011
Subjects: subject: Mathematics
subject: FOS: Mathematics

description: This dissertation takes two approaches - martingale and backward stochastic differential equation (BSDE) - to solve non-zero-sum stochastic differential games in which all players can control and stop the reward streams of the games. Existence of equilibrium stopping rules is proved under some assumptions. The martingale part provides an equivalent martingale characterization of Nash equilibrium strategies of the games. When using equilibrium stopping rules, Isaacs' condition is necessary and sufficient for the existence of an equilibrium control set. The BSDE part shows that solutions to BSDEs provide value processes of the games. A multidimensional BSDE with reflecting barrier is studied in two cases for its solution: existence and uniqueness with Lipschitz growth, and existence in a Markovian system with linear growth rate.

description: For high-resolution separators like the projected Super-FRS at FAIR, an adapted and accurate ion-optical model considering realistic B-dependent magnet parameters is crucial in achieving the desired parameters (e.g. resolution) and to enable a fast optimization. Starting from the magnetic field measurements and simulations, rigidity-dependent Taylor transfer maps are generated for the Super-FRS preseparator dipole magnets. The effects of the magnetic saturation in the steel yoke on the image aberrations are analyzed.

description: We match the vacuum, stationary, cylindrically symmetric solution of Einstein's field equations with $Λ$, in a form recently given by Santos, as an exterior to an infinite cylinder of dust cut out of a Gödel universe. There are three cases, depending on the radius of the cylinder. Closed timelike curves are present in the exteriors of some of the solutions. There is a considerable similarity between the spacetimes investigated here and those of van Stockum referring to an infinite cylinder of rotating dust matched to vacuum, with $Λ=0$.

Two Essays in Financial Engineering

description: This dissertation consists of two parts. In the first part, we investigate the potential impact of wrong-way risk on calculating credit valuation adjustment (CVA) of a derivatives portfolio. A credit valuation adjustment (CVA) is an adjustment applied to the value of a derivative contract or a portfolio of derivatives to account for counterparty credit risk. Measuring CVA requires combining models of market and credit risk. Wrong-way risk refers to the possibility that a counterparty's likelihood of default increases with the market value of the exposure. We develop a method for bounding wrong-way risk, holding fixed marginal models for market and credit risk and varying the dependence between them. Given simulated paths of the two models, we solve a linear program to find the worst-case CVA resulting from wrong-way risk. We analyze properties of the solution and prove convergence of the estimated bound as the number of paths increases. The worst case can be overly pessimistic, so we extend the procedure for a tempered CVA by penalizing the deviation of the joint model of market and credit risk from a reference model. By varying the penalty for deviations, we can sweep out the full range of possible CVA values for different degrees of wrong-way risk. Here, too, we prove convergence of the estimate of the tempered CVA and the joint distribution that attains it. Our method addresses an important source of model risk in counterparty risk measurement. In the second part, we study investors' trading behavior in a model of realization utility. We assume that investors' trading decisions are driven not only by the utility of consumption and terminal wealth, but also by the utility burst from realizing a gain or a loss. More precisely, we consider a dynamic trading problem in which an investor decides when to purchase and sell a stock to maximize her wealth utility and realization utility with her reference points adapting to the stock's gain and loss asymmetrically. We study, both theoretically and numerically, the optimal trading strategies and asset pricing implications of two types of agents: adaptive agents, who realize prospectively the reference point adaptation in the future, and naive agents, who fail to do so. We find that an adaptive agent sells the stock more frequently when the stock is at a gain than a naive agent does, and that the adaptive agent asks for a higher risk premium for the stock than the naive agent does in equilibrium. Moreover, compared to a non-adaptive agent whose reference point does not change with the stock's gain and loss, both the adaptive and naive agents sell the stock less frequently, and the naive agent requires the same risk premium as the non-adaptive agent does.
Two Papers of Financial Engineering Relating to the Risk of the 2007--2008 Financial Crisis

description: This dissertation studies two financial engineering and econometrics problems relating to two facets of the 2007-2008 financial crisis. In the first part, we construct the Spatial Capital Asset Pricing Model and the Spatial Arbitrage Pricing Theory to characterize the risk premiums of futures contracts on real estate assets. We also provide rigorous econometric analysis of the new models. Empirical study shows there exists significant spatial interaction among the S&P/Case-Shiller Home Price Index futures returns. In the second part, we perform empirical studies on the jump risk in the equity market. We propose a simple affine jump-diffusion model for equity returns, which seems to outperform existing ones (including models with Levy jumps) during the financial crisis and is at least as good during normal times, if model complexity is taken into account. In comparing the models, we made two empirical findings: (i) jump intensity seems to increase significantly during the financial crisis, while on average there appears to be little change of jump sizes; (ii) finite number of large jumps in returns for any finite time horizon seem to fit the data well both before and after the crisis.

description: We propose the use of quantum optical systems to perform universal simulation of quantum dynamics. Two specific implementations that require present technology are put forward for illustrative purposes. The first scheme consists of neutral atoms stored in optical lattices, while the second scheme consists of ions stored in an array of micro--traps. Each atom (ion) supports a two--level system, on which local unitary operations can be performed through a laser beam. A raw interaction between neighboring two--level systems is achieved by conditionally displacing the corresponding atoms (ions). Then, average Hamiltonian techniques are used to achieve evolutions in time according to a large class of Hamiltonians.

description: Maternal psychosocial stress can negatively impact gestational length and development of the fetus. These effects may be sex-specific but have not been extensively studied. The objective of this study was to examine the associations between prenatal maternal stress and birth outcomes and whether effects are modified by sex. Prenatal maternal stress was indexed by a maternal negative life events (NLEs) score ascertained in 527 urban mothers; a higher NLE score indicates greater stress. Birth outcomes included gestational age, preterm birth (PTB) (<37 weeks), and birthweight for gestational age z-scores. Modified Poisson regression and linear models were used to evaluate associations of prenatal NLE scores with birth outcomes. Sex differences were assessed by inclusion of an interaction term for sex by NLE score and in sex-stratified analyses. In analyses adjusted for maternal age, education, race/ethnicity, and pre-pregnancy body mass index (BMI), increasing prenatal stress was associated with shortened gestational age (days) (β = −0.63, [95% CI −1.20, −0.06]). This effect was sex specific, with increasing prenatal stress associated with shortened gestational age, as well as increased risk of PTB, in male infants (β = −1.35 [95% CI −2.17, −0.54] and RR = 1.18 [95% CI 0.99, 1.42], respectively) but not female infants (β = 0.15 [95%CI −0.63, 0.94] and RR = 0.85, [95%CI 0.65, 1.11], respectively). Prenatal stress was not associated with birthweight z-scores. Our results support the importance of psychosocial stress as a programming factor that may have sex-specific effects for adverse fetal outcomes. Understanding sex-specific effects of prenatal stress on birth outcomes may inform prevention strategies. LAY SUMMARY Higher stress experienced by mothers in pregnancy was associated with shorter length of pregnancy and the effect was stronger in male infants when compared to female infants.

description: The formation of a superstructure - with a related Moiré pattern - plays a crucial role in the extraordinary optical and electronic properties of twisted bilayer graphene, including the recently observed unconventional superconductivity. Here we put forward a novel, interdisciplinary approach to determine the Moiré angle in twisted bilayer graphene based on the photonic spin Hall effect. We show that the photonic spin Hall effect exhibits clear fingerprints of the underlying Moiré pattern, and the associated light beam shifts are well beyond current experimental sensitivities in the near-infrared and visible ranges. By discovering the dependence of the frequency position of the maximal photonic spin Hall effect shift on the Moiré angle, we argue that the latter could be unequivocally accessed via all-optical far-field measurements. We also disclose that, when combined with the Goos-Hänchen effect, the spin Hall effect of light enables the complete determination of the electronic conductivity of the bilayer. Altogether our findings demonstrate that sub-wavelength spin-orbit interactions of light provide a unprecedented toolset for investigating optoelectronic properties of multilayer two-dimensional van der Waals materials.

description: Over the last two decades, Bolivian migration inside South America has had two main destinations: Buenos Aires (Argentina) and São Paulo (Brazil). There is a long tradition of Bolivian migration to Buenos Aires, however, in the late twentieth century São Paulo has also became attractive because of Argentina's economic crisis and Brazil's impressive development. The central part of this thesis presents vast information about the formation and daily lives of these two Little Bolivias, including both socioeconomic and sociocultural aspects of the two immigrant groups, with the objective of giving the reader a comparative understanding of both scenarios. The issues of assimilation are a fundamental part of this thesis since the capacity of making its way to be assimilated together with the receptiveness of the host societies are the conditions that propitiate a debate about the future of these Bolivian collectivities in Buenos Aires and São Paulo. Hence, this thesis aims to make an innovative comparative analysis of the contemporary realities of Bolivian immigrants in both cities, looking for similarities and differences, trying to understand the unfolding of each process, and the experiences of adaptation and cultural assimilation in two of the most referential cities in South America.

description: Supersymmetry (SUSY) in quantum mechanics is extended from square-integrable states to those satisfying the outgoing-wave boundary condition, in a Klein-Gordon formulation. This boundary condition allows both the usual normal modes and quasinormal modes with complex eigenvalues. The simple generalization leads to three features: the counting of eigenstates under SUSY becomes more systematic; the linear-space structure of outgoing waves (nontrivially different from the usual Hilbert space of square-integrable states) is preserved by SUSY; and multiple states at the same frequency (not allowed for normal modes) are also preserved. The existence or otherwise of SUSY partners is furthermore relevant to the question of inversion: are open systems uniquely determined by their complex outgoing-wave spectra?

description: The evolution of electronics has become the staple thrust of modern scientific innovation: a need for advancing materials engineered for our equally rapidly advancing needs and computing requirements has fueled recent wealth of new materials. Here, I use the ideals of exotic materials design to answer this need, specifically for 2D materials. Two-dimensional (2D) van der Waals materials with in-plane anisotropy are of great interest for directional transport of charge and energy. I perform solid state synthesis to produce several such materials: an intrinsic antiferromagnet, superatomic semiconductors, and a polytype system with a component that displays the possibilities of Weyl nodes.The former, chromium sulfur bromide (CrSBr), is first synthesized, then fully studied structurally, compositionally, electronically, and magnetically. Second harmonic generation (SHG), more advanced than older techniques such as magneto-optical Kerr spectroscopy or Raman spectroscopy, allows us to fully understand the magnetic symmetry in this system as an interlayer antiferromagnetic and intralayer ferromagnetic in-plane anisotropic material. I also introduce published work in which we integrate CrSBr into different devices to show the utility of this fundamental research into a more practical application setting. It is used to stimulate more magnetic response from graphene — promising ultra-thin magnetic memory or sensory devices in future projects. Applying strain and external magnetic fields provides another tuning knob through which to access different functional modalities. In the latter third of this dissertation, we report a layered van der Waals semiconductor with in-plane anisotropy built upon the superatomic units of Mo₆S₃Br₆ (MSB), a robust construction with a direct gap of 1.64 eV. Next, MSB and Re₆Se₈Cl₂, another analogous superatomic vdW material, are potential candidates for optoelectronic applications; we qualify this by studying their Auger dynamics as a measure of quantum efficiency. Finally, layered van der Waals (vdW) materials belonging to the MM’Te₄ structure class have recently received intense attention due to their ability to host exotic electronic transport phenomena, such as in-plane transport anisotropy, Weyl nodes, and superconductivity. In summary, we have discovered two ternary exfoliatable vdW TMD polytypes with the composition TaFeTe₄, one of which (ꞵ) shows the prerequisite symmetry elements to be a type-II Weyl semimetal. This dissertation is a treatise to solid state synthesis, exploration into the more exotic spectrum of 2D materials, and robust and eclectic methods used to paint a full picture of different magnetic and electronic systems within.
The Effect Of Temporary Import Protection On Future Prices

description: This paper determines the effect of a temporary tariff or import quota on future prices. It assumes that the home country consumes a large portion of world output so that the tariff influences world prices. The temporary tariff affects current investment decisions and this is the channel through which the tariff influences future world prices. The tariff has offsetting effects on future prices because it expands future domestic supply and contracts future foreign supply. For a benchmark case it is shown that the net effect on future prices is positive, i.e., the temporary tariff increases domestic prices even after the tariff measure has expired.

description: Nanoparticles as novel materials have unique properties due to their incredibly small sizes. Ensembles of nanoparticles not only collect their intrinsic properties but also generate new ones when nanoparticles are sufficiently close. One important way of forming nanostructures entails the assembly of nanoparticle monolayers at liquid interfaces. It is important to understand how the iron oxide nanoparticles transport in a liquid phase and on a liquid/liquid interface and self-assemble into nanostructures over time. As a preliminary research topic before the comprehensive small angle X-ray scattering (SAXS) study, real-time optical reflection of incident p-polarized light near Brewster’s angle shows that after drop-casting iron oxide nanoparticle heptane dispersion on top of a diethylene glycol (DEG) liquid substrate, an iron oxide nanoparticle layer forms at the DEG/heptane interface, and it self-limits to one monolayer even when there are excess nanoparticles dispersed in the upper heptane phase. As is needed for the high time resolution and X-ray exposure minimization requirements of kinetics studies, a new cell with walls at angles is designed to significantly reduce the size of the meniscus, which enables the collection of much larger signals in the SAXS images of ordered arrays of nanoparticles at liquid/air interfaces, along with the observation of extremely high degrees of order. Spatial and temporal SAXS scans show that 8.6 and 11.8 nm iron oxide nanoparticles in heptane drop-cast on top of a heptane layer atop a DEG layer are trapped at the DEG/heptane interface to generally form a single ordered, hexagonally close-packed monolayer, and this occurs long before the heptane evaporates. The morphology of the monolayer is independent of the number of nanoparticles used in the formation process. Many nanoparticles remain dispersed in the heptane after this nanoparticle assembly. Assembly occurs faster than expected from considering only the diffusion of nanoparticles from the drop-cast site to this liquid/liquid interface. And, on the same time scale there is a concomitant decrease in the SAXS form factor from disordered nanoparticles. X-ray beam transmission at different vertical heights characterizes the heptane and DEG bulk and interfacial regions, while monitoring the time dependence of SAXS at and near the DEG/heptane interface gives a clear picture of the evolution of nanoparticle assembly at this liquid/liquid interface. These SAXS observations of self-limited nanoparticle monolayer formation at the DEG/heptane interface are consistent with those using the less direct method of real-time optical reflection monitoring of that interface.

description: $\mathrm{MnBi_2Te_4}$ has recently been established as an intrinsic antiferromagnetic (AFM) topological insulator and predicted to be an ideal platform to realize quantum anomalous Hall (QAH) insulator and axion insulator states. We performed comprehensive studies on the structure, nontrivial surface state and magnetotransport properties of this material. Our results reveal an intrinsic anomalous Hall effect arising from a non-collinear spin structure for the magnetic field parallel to the $c$-axis. We also observed remarkable negative magnetoresistance under arbitrary field orientation below and above the Neel temperature (T$_N$), providing clear evidence for strong spin fluctuation-driven spin scattering in both the AFM and paramagnetic states. Further, we found that the nontrivial surface state opens a large gap (~85 meV) even at temperatures far above T$_N$ = 25K. These findings demonstrate that the bulk band structure of $\mathrm{MnBi_2Te_4}$ is strongly coupled to the magnetic structure and that a net Berry curvature in momentum space can be created in a canted AFM state. In addition, our results imply that the gap opening in the surface states is intrinsic, likely caused by the strong spin fluctuations near the surface layers.

Destabilizing Exchange Rate Speculation: A Counterexample To Milton Friedman

description: This paper constructs a counterexample to Milton Friedman's assertion that speculation must stabilize the exchange rate. It is shown that in the case of persistent shocks to monetary growth rates, currency speculators increase exchange rate volatility by buying "strong" currencies and selling "weak" currencies. On the other hand, Friedman's claim is supported in another example with transient monetary shocks. The exchange rate is then stabilized when speculators buy temporarily "weak" currencies in anticipation of their future appreciation.

description: We study the ground state and low-lying excited states of the Kitaev-Heisenberg model on a ladder geometry using the density matrix renormalization group and Lanczos exact diagonalization methods. The Kitaev and Heisenberg interactions are parametrized as $K=\sinϕ$ and $J=\cosϕ$ with an angle parameter $ϕ$. Based on the results for several types of order parameters, excitation gaps, and entanglement spectra, the $ϕ$-dependent ground-state phase diagram is determined. Remarkably, the phase diagram is quite similar to that of the Kitaev-Heisenberg model on a honeycomb lattice, exhibiting the same long-range ordered states, namely rung-singlet (analog to Néel in 3D), zigzag, ferromagnetic, and stripy; and the presence of Kitaev spin liquids around the exactly solvable Kitaev points $ϕ=\pmπ/2$. We also calculate the expectation value of a plaquette operator corresponding to a $π$-flux state in order to establish how the Kitaev spin liquid extends away from the $ϕ=\pmπ/2$. Furthermore, we determine the dynamical spin structure factor and discuss the effect of the Kitaev interaction on the spin-triplet dispersion.

description: Multi-photon emitters are a sought-after resource in quantum photonics. Nonlinear interactions between a multi-level atomic system and a coherent drive can lead to resonant two-photon emission, but harvesting light from this process has remained a challenge due to the small oscillator strengths involved. Here we present a study of two-photon resonance fluorescence at microwave frequencies, using a superconducting, ladder-type artificial atom, a transmon, strongly coupled to a waveguide. We drive the two-photon transition between the ground and second-excited state at increasingly high powers and observe a resonance fluorescence peak whose intensity becomes comparable to single-photon emission until it splits into a Mollow-like triplet. We measure photon correlations of frequency-filtered spectral lines and find that while emission at the fundamental frequency stays antibunched, the resonance fluorescence peak at the two-photon transition is superbunched. Our results provide a route towards the realization of multi-photon sources in the microwave domain.

description: The potential of using rabbit manure as inoculum for biogas production was evaluated through batch assays using bean straw as substrate. The microbial diversity in the rabbit manure included lignin-degrading bacteria (classes Bacteroidia, Bacilli and Clostridia) as well as key acetoclastic (Matheanosarcina and Methanosaeta), and hydrogenotrophic (Methanobacterium, Methanolinea, and Methanovebribacter) archaea. The effects of particle size, substrate to inoculum ratio (S/X) and pH adjustment were studied to improve the inoculum activity. The adjustment of the pH entailed the highest improvement in methane production (515%) and rate (164%). However, high S/X, (3–4), resulted in the acidification of the processes, denoting an imbalance between hydrolytic bacteria and methanogenic archaea in the rabbit manure. This confirmed that the use of rabbit manure as inoculum could sustain anaerobic digestion from agricultural residues, although a proper enrichment and adaptation is necessary to ensure an appropriate methane production.
Two-stage Continual Reassessment Method and Patient Heterogeneity for Dose-finding Studies

description: The continual reassessment method (CRM) is a widely used model-based design in Phase I dose-finding studies. This dissertation examines two extensions of CRM: one is a two-stage method and the other is a method that accounts for patient heterogeneity. Originally proposed in the Bayesian framework, CRM starts by testing the first patient at the prior guess of the maximum tolerated dose (MTD). However, there are safety concerns with this approach as practitioners often prefer to start from the lowest dose level and are reluctant to escalate to higher dose levels without testing the lower ones with a sufficient number of patients. This calls for a two-stage design, where the model-based phase is preceded by a pre-specified dose escalation phase, and the phase transitions when any dose-limiting toxicity (DLT) occurs. In the first part of this dissertation, I propose a theoretical framework to build a two-stage CRM based on the coherence principle and prove the unique existence of the most conservative and coherent initial design. An accompanying calibration algorithm is formulated to facilitate design implementation. We demonstrate that by using real trial examples, the algorithm yields designs with competitive performance compared to the conventional design which uses a much more labor intensive trial-and-error approach. Furthermore, we show that this algorithm can be applied in a timely and reproducible manner. In addition to the two-stage method, we also take into account of patient's heterogeneity in drug metabolism rate that can result in different susceptibility to drug toxicity. This led to a risk-adjusting design for identifying patient-specific MTDs. The existing dose-finding designs which incorporate patient heterogeneity deal either with only categorical risk factor or with continuous risk factor using models based on strong parametric assumptions. We propose a method that uses a flexible semi-parametric model to identify patient-specific MTDs, adjusting for either categorical or continuous risk factor. Initially, our method assigns dose to patients using the aforementioned two-stage CRM ignoring any patient heterogeneity, and tests the risk effect as trial proceeds. It then transitions to a risk-adjusting stage only if sufficient risk effect on toxicity outcome is observed. The performance of this multi-stage design is evaluated under various scenarios, using dosing accuracy measures calculated based on the final model estimate at the end of a trial and on the intra-trial dose allocation. The results are compared to the conventional two-stage CRM without considering patient heterogeneity. Simulation results demonstrate a substantial improvement in dosing accuracy in scenarios where there are true risk effects on toxicity probability; and in situations where risk factors do not have an effect, the performance of the proposed method is also comparable to that of the conventional design.

description: In this study, we have presented the synthesis of novel 2,5,7-triarylimidazo[1,2-a]pyridine-8-carbonitriles from 2-amino-4,6-diarlypyridine-3-carbonitrile and nitrostyrene using FeCl3 (20 mol%) as Lewis acid under solvent-free conditions. A library of compounds with diverse substitutions have also been synthesized and screened for in-vitro anti-cancer activity against various cell lines such as A549 (Lung), HCT-116 (Colon), SW-620 (Colon), and MIAPACA (Pancreas).
U.S. Federal States in Transatlantic Trade and Investment Policy Making: Actors, Access, Aspirations

description: In their negotiations for the Transatlantic Trade and Investment Partnership (TTIP) between 2011 and 2016, the European Union and the United States of America (U.S.) aimed to not only reduce tariffs but to also establish regulatory coherence. For the U.S. federal states, the proposed comprehensive deal could offer both possibilities to expand transatlantic trade as well as threats to their legislative authority. This study investigates why and how some states represent their transatlantic trade promotion and trade policy interests despite constitutional limitations, why there is variation regarding these two topics of states’ interest representation and what intergovernmental conflicts arise. Based on original qualitative expert interviews, the analysis shows that U.S. states as noncentral governments are viable actors in transatlantic trade and investment relations. It is evident that a small number of mostly progressive state legislators actively engage U.S. federal and European officials to prevent the loss of state regulatory authority. Regarding the proposed trade deal, interest representation is centered around issues of federalism and sovereignty rather than economic growth opportunities. While trade promotion remains the key driver of states’ overall transatlantic activities, these findings expand our view on states’ international affairs beyond economic development.

description: Chains of parametrically driven, damped pendula are known to support soliton-like clusters of in-phase motion which become unstable and seed spatiotemporal chaos for sufficiently large driving amplitudes. We show that the pinning of the soliton on a "long" impurity (a longer pendulum) expands dramatically its stability region whereas "short" defects simply repel solitons producing effective partition of the chain. We also show that defects may spontaneously nucleate solitons.
