description: Hydrogen is currently considered by many as the “fuel of the future”. It is particularly favoured as a replacement for fossil fuels due to its clean-burning properties; the waste product of combustion being water. While hydrogen is relatively easy to produce, there is currently a lack of practical storage methods for molecular H2, and this is greatly hindering the use of hydrogen as a fuel. Gases are normally stored in vessels under only moderate pressures and in liquid form where possible, which yields the highest energy density. However, to store reasonable quantities of hydrogen in similar volume containers, cryogenic temperatures or extreme pressure are required. Many potential hydrogen storage technologies are currently under investigation, including adsorption on metal hydrides, nanotubes and glass microspheres, and the chemical breakdown of compounds containing hydrogen to release H2. Recent studies have sparked interest in hydrates as a potential hydrogen storage material. The molecular storage of hydrogen in clathrate hydrates could offer significant benefits with regard to ease of formation/regeneration, cost and safety, as compared to other storage materials currently under investigation. Here, we present new experimental hydrate stability data for sII forming hydrogen–water (up to pressures of 180 MPa) and hydrogen–water–tetrahydrofuran systems, the structure-H forming hydrogen–water–methyclycohexane system, and semi-clathrate forming hydrogen–water–tetra-n-butyl ammonium bromide/tetra–n-butyl ammonium fluoride systems.

description: We present a study of the recently discovered spatially-extended chaotic state known as spiral-defect chaos, which occurs in low-Prandtl-number, large-aspect-ratio Rayleigh-Benard convection. We employ the modulus squared of the space-time Fourier transform of time series of two-dimensional shadowgraph images to construct the structure factor ${S}({\vec k},ω)$. This analysis is used to characterize the average spatial and temporal scales of the chaotic state. We find that the correlation length and time can be described by power-law dependences on the reduced Rayleigh number $ε$. These power laws have as yet no theoretical explanation.

description: We present narrow-band H-alpha, [S II], and [O I] Hubble Space Telescope images of the young planetary nebula GL 618. This object is a compact, bipolar nebula that is currently undergoing the transition from asymptotic giant branch star to planetary nebula. Our images confirm the presence of at least three highly collimated outflows emanating from the central regions of GL 618. We also detect H-alpha emission close to the central dust lane and in an extended scattered light halo. The three outflows are occurring simultaneously in this object, as opposed to being the result of a precessing jet. We derive an inclination for the brightest outflow in the East lobe of 39 degrees. This differs from the previous estimate of 45 degrees. In addition, our results indicate that the outflows seen in GL 618 are probably not coplanar. Line strengths derived from the narrow-band images indicate a shock velocity in the range of 40 - 100 km/s. Based on the shock velocity we estimate that the age of the outflows is less than 500 years. The outflows seen in the optical images of GL 618 are related to features seen in near-IR, CO and CS maps of this object. This relationship indicates that the outflows are playing a major role in the morphological evolution of this young planetary nebula, interacting with and shaping the neutral envelope surrounding GL 618. We discuss the implications of these jets and their interaction with the neutral envelope in the context of current models of planetary nebula formation.

description: Tuberculosis (TB) is the leading cause of death from infectious diseases in the world, affecting more than ten million patients each year. However, multi-drug resistance (MDR-TB) threatens progress achieved in TB care and control, and there are few drugs available to treat MDR-TB. Our overall aim was to identify anti-TB natural products from microbes sourced from unique environments. This thesis presents efforts to achieve an effective approach to identify anti-TB microbial natural products with the combination of one strain many compounds (OSMAC) strategy, NMR fingerprint and principal component analysis. The thesis begins with an introduction of TB and the current anti-TB drugs and candidates. It also covers a review on anti-TB natural products from marine microbe and endophyte origin and analysis of their physicochemical properties using Lipinski’s rule of five as well as the ChemGPS tool. As part of a research program aiming to identify anti-TB microbial constituents, a cell-based screening assay was developed to screen 2562 crude extracts. Among the active hits, 46 actinomyces isolated from marine, desert or Traditional Chinese Medicines were selected for further chemical investigation according to their chemical profiles or anti-TB activities. The results are presented in chapters 2 to 7.

description: In petroleum production systems, hydrate morphology is observed to be influenced by the crude oil composition. This work is aimed at identifying which crude oil compositional parameters that need to be determined in order to evaluate natural anti-agglomerating properties of crude oils, i.e. the critical compositional descriptors. The compositional features of 22 crude oils have been studied, and multivariate data analysis has been used to investigate the possibility for correlations between several crude oil properties. The results show that biodegradation together with a relatively large amount of acids are characteristic for non-plugging crude oils, while excess of basic compounds is characteristic for plugging crude oils. The multivariate data analysis shows a division of the nonbiodegraded oils, which are all plugging, and the biodegraded oils. In addition, the biodegraded oils seem to be divided into two groups, one with plugging oils and one with mostly non-plugging oils. The results show that the wettability can be predicted from the variables biodegradation level, density, asphaltene content and TAN.

description: Emotion regulation is a topic of great interest due to its relevance to navigating everyday life, as well as its relevance to psychopathology. Recent research indicates that beliefs about the automaticity of mood regulation are critical to psychological health. In the present study we assessed beliefs about the automaticity of positive mood regulation in relationship to self-reported mood symptoms and explicit emotion regulation strategies. Participants (n = 200) completed an online survey including a scale assessing beliefs about automatic downregulation of positive emotions (i.e. BAMR-PED), beliefs about automatic mood regulation for negative emotions, mood symptoms, and emotion regulation strategies. Results suggested that beliefs about automatic positive emotion regulation were associated with unhelpful emotion regulation strategies and reduced negative affect as well as fewer depressive, manic, and anxiety symptoms. Test-retest of the novel BAMR-PED measure was tested with a further sample (n = 46) and found to be acceptable. Future research should explore how these automatic beliefs have relevance to clinical disorders characterised by positive emotion disturbance, such as bipolar disorder.

Essays on Open Economy Macroeconomics

Year: 2018
Subjects: Economics

Monetary policy

description: This Ph.D. dissertation contains three essays on Open Economy Macroeconomics. The first chapter investigates monetary policy problem of emerging economies known as the Tosovsky Dilemma, which says that when an emerging economy experiences a boom associated with capital inflows and exchange rate appreciation, it is not appealing to tighten monetary policy to counteract inflationary pressures as this might further exacerbate inflows and appreciation. In the chapter, I develop an intertemporal general equilibrium framework of the monetary transmission mechanism to investigate how this dilemma shapes optimal monetary policy. In the model, financing is decentralized and collateralized by physical capital, which is nontradable and costly to adjust over time. The Dilemma materializes when there is a positive external shock that increases capital inflows and generates real exchange rate appreciation and inflation in the nontradable sector, all of which are inefficient. Contrary to conventional wisdom, the Ramsey optimal monetary policy calls for lowering the policy rate in such circumstances in order to suppress capital inflows and appreciation, while accepting inflation in the nontradable sector. If the capital flows can be controlled by an additional policy instrument, then optimal policy becomes countercyclical, as in the conventional framework without the Dilemma.
      The second and third chapters focus on dynamics of labor shares over the business cycles in small open economies. The second chapter uses annual labor shares data of 40 years for 35 small open economy countries and finds three empirical regularities. First, labor shares are not constant, but they are as volatile as output. Second, labor shares in emerging economies are about twice as volatile as labor shares in advanced economies. Third, labor shares in emerging economies are procyclical on average, whereas they are countercyclical in most advanced economies. The empirical findings offer a skeptical view of the conventional beliefs about the unitary elasticity of substitution between capital and labor, and countercyclical labor shares in the short-run.
      The third chapter paper builds a theoretical model which can comprehensively explain the empirical findings in the second chapter. The model is a dynamic stochastic general equilibrium, small open economy, composed of tradable and nontradable sectors with CES production functions. In the model, there are two margins of labor share fluctuations over the business cycles, which are fluctuations of the capital-labor ratio in each sector and fluctuations in the relative value of sectoral production. The estimated models show a countercyclical labor share and volatility near that of output in Canada, and procyclical and excessively volatile labor share in Mexico, all of which are in line with the data.

description: We introduce a new number-theoretic spin chain and explore its thermodynamics and connections with number theory. The energy of each spin configuration is defined in a translation-invariant manner in terms of the Farey fractions, and is also expressed using Pauli matrices. We prove that the free energy exists and exhibits a unique phase transition at inverse temperature beta = 2. The free energy is the same as that of a related, non translation-invariant number-theoretic spin chain. Using a number-theoretic argument, the low-temperature (beta > 3) state is shown to be completely magnetized for long chains. The number of states of energy E = log(n) summed over chain length is expressed in terms of a restricted divisor problem. We conjecture that its asymptotic form is (n log n), consistent with the phase transition at beta = 2, and suggesting a possible connection with the Riemann zeta function. The spin interaction coefficients include all even many-body terms and are translation invariant. Computer results indicate that all the interaction coefficients, except the constant term, are ferromagnetic.

description: This dissertation examines an underexplored type of innovation - the discovery of new resources. Schumpeter distinguishes among five types of innovation: new products, new processes, new organizations, new markets, and new resources. Most prior work has focused on the first three types of innovation. This study focuses on the last type of innovation, the discovery of new resources, in creative industries where talent is the most important resource of creativity and profit. This dissertation is comprised of three chapters. Each of the chapters examines a strategy or an environmental change such as unbundling, digitalization, and cross-border acquisition which may facilitate or weaken the discovery of new talent and experiment with new artists. In the first chapter, I explore the impact of unbundling on the discovery of new talent.  The results highlight the trade-off between breadth-oriented experimentation (experimenting with more new alternatives by producing unbundled products) and depth-oriented experimentation (collecting more accurate information on fewer alternatives by producing bundled products) and suggest that unbundling may facilitate firms’ breadth-oriented experimentation and the discovery of new talent. In the second chapter, I investigate whether digitalization (digital market) facilitated the discovery of new talent by entrepreneurial firms. Digitalization offers diverse niche opportunities from a long-tail market and decreases the cost of experimenting with new artists. However, the findings from this chapter suggest that entrepreneurial firms did not benefit from such opportunities; iTunes and YouTube did not facilitate entrepreneurial firms’ discovery of new talent and experimentation with new artists (compared to incumbent firms). In the third chapter, I turn to look at the impact of foreign ownership or capital on the discovery of new domestic talent. The “liability of foreignness” argument suggests that foreign ownership may weaken the discovery of new talent from the host country because foreign owners may lack a good understanding of the host country culture. This study analyzes the case of Sony’s acquisition of CBS Records (a US major label) in 1988, which is the first merger by a Japanese firm with a firm of a distant culture. The results suggest that Sony did not undermine CBS Records’ discovery of domestic new talent but instead increased the popularity of new domestic artists in CBS Records and its subsidiaries.

description: This paper presents a novel framework, MGNER, for Multi-Grained Named Entity Recognition where multiple entities or entity mentions in a sentence could be non-overlapping or totally nested. Different from traditional approaches regarding NER as a sequential labeling task and annotate entities consecutively, MGNER detects and recognizes entities on multiple granularities: it is able to recognize named entities without explicitly assuming non-overlapping or totally nested structures. MGNER consists of a Detector that examines all possible word segments and a Classifier that categorizes entities. In addition, contextual information and a self-attention mechanism are utilized throughout the framework to improve the NER performance. Experimental results show that MGNER outperforms current state-of-the-art baselines up to 4.4% in terms of the F1 score among nested/non-overlapping NER tasks.

Year: 2023
Subjects: subject: thiopene
subject: UV emission
subject: photochromism

description: Thiophene-based materials are some of the most versatile conjugated materials due to their combination of environmental stability and ease of synthetic modification. They are widely employed for photoelectronic applications, such as Organic Photovoltaics, however, thiophene-based materials in emissive applications fall far behind, possibly because of the limited fluorescent quantum yields in both solution and the solid state. Regardless of this limitation, thiophene-based materials still provide a number of characteristics that have made them popular systems for technological applications. In addition to the stability and synthetic diversity already discussed, these characteristics include controllable color tuning of absorption and emission, good charge mobility, and the ability to produce materials with low band gaps. The interest in emissive thiophene derivatives has also increased due to various approaches for overcoming the commonly reduced fluorescence efficiencies, as well as new applications such as fluorescent biomarkers. Besides the emissive properties, thiophene-based functional materials for photochromic systems are also studied intensively. Molecules in this category are usually termed "dithienylethene" concerning the structural motif of two thiophene rings bridged at their third position with an ethene group. Dithienylethenes (DTEs) outperform other photochromic systems in many ways, such as their excellent thermal stability in both isomers, high fatigue resistance, and switchability in the crystalline state. Before and after the irradiation, the two isomers differ not only in the absorption spectra but also in various physical and chemical properties, such as refractive indices, dielectric constants, oxidation-reduction potentials, and geometrical structures. The instant property changes without processing lead to their use in various optoelectronic devices, such as optical memory, photo-optical switching, display, and nonlinear optics. […]
Denuded Dwarfs Demystified: Gas Loss from dSph Progenitors and Implications for the Minimum Mass of Galaxies

description: The placement of early-type dwarf galaxies (dSphs and dEs) with respect to the Potential Plane defined by pressure-supported late-type dwarf galaxies (dIs and BCDs) has been determined from surface brightness profiles. dEs and the most luminous dSphs lie on the Plane, suggesting that they emerged from late-type dwarfs that converted most of their gas into stars. However, there is a critical value of the potential at which dSphs start to fall systematically below the Plane, with the deviation growing as the potential becomes shallower. The displacements are attributed to depletion of baryons through gas loss, smaller galaxies having lost proportionately more gas. The critical potential corresponds to an escape velocity of 50 $\pm$ 8 km/s, which is what is expected for gas with a temperature of 13,000 $\pm$ 4,000 K, typical of a low-metallicity HII region. This suggests that photoionization was responsible for instigating the loss of gas by galaxies with potentials shallower than the critical value, with evacuation occurring over a few tens of millions of years. Extreme ratios of dynamical to luminous masses observed for the smallest dSphs are an artifact of mass loss. Because the efficiency with which gas was converted into stars was lower for dSphs with shallower potentials, there should be a minimum baryonic mass for a galaxy below which the stellar mass is negligible. Gross extrapolation of the trend of inferred gas masses with stellar masses suggests a value between 500 and 10,000 M$_\odot$. The corresponding dynamical mass is below 10$^6$ M$_\odot$.

title: De-Domesticating the Actor: Applying Ankoku Butoh's Training Process of De-domestication to Develop Presence in Western Actor Training through Experiences of Awareness, Discipline and Energy

description: The primary aim of this research is to contribute to existing Western actor training methods that explore the experience of ‘presence’ in actor training environments, through the construction of a suite of exercises, formulated from the Japanese psychophysical performance practice of ankoku butoh (‘dance of darkness’). The research differentiates between the states of ‘being present’ and of ‘having presence’, with ‘being present’ equivalent to being in the moment, and ‘having presence’ representing an actor’s authentic presence as perceived by others. Subsequently, exercises derived from this research are specifically designed to develop each state individually, and specifically in the order of ‘being present’ and ‘having presence’. The process of ‘de-domestication’, as discussed in this research, and in its application in ankoku butoh training, refers to the elements of awareness, discipline and energy, experiences that this research posits are central to the development of presence as a performance technique. Utilising a mixed methodology of action research and reflective practice within the research framework, the study incorporated two action cycles of practical workshops whereby actor-participants experienced ankoku butoh-derived exercises to examine the possibilities of enhancing presence in actors. Cyclic principles of development, action, practice and reflection were utilised to determine if/how the exercises generated or encouraged the development of the states of ‘being present and of ‘having presence’ in the participants. The outcome of the research was the creation of a suite of exercises formulated from ankoku butoh’s process of de-domestication that may be used for enhancing presence in actors. Further applications of the exercises formulated from this study may contribute to the development of presence in other non-acting physical training disciplines such as martial arts.

description: High-Frequency (HF) radar is well suited to the surveillance of low-earth-orbit space. For large targets, a small deployable HF radar is able to match the detection performance of much larger space surveillance radar systems operating at higher frequencies. However, there are some unique challenges associated with the use of HF, including the range--Doppler coupling bias, coarse detection-level localisation, and the presence of meteor returns and other unwanted signals. This paper details the use of HF radar for space surveillance, including signal processing and radar product formation, tracking, ionospheric correction, and orbit determination. It is shown that by fusing measurements from multiple passes, accurate orbital estimates can be obtained. Included are results from recent SpaceFest trials of the Defence Science and Technology Group's HF space surveillance radar, achieving real-time wide-area surveillance in tracking, orbit determination, and cueing of other space surveillance sensors.

description: Ab initio prediction of the electronic properties of solids is traditionally performed using groundstate Density Functional Theory. These methods are unreliable however, for a class of important problems involving weak attractive forces. These problems include (i) the energetics of hydrogen storage and metal interactions in graphene, (ii) cohesion properties of some polymer systems and (iii) possibly, the weak hydrophobic forces in biomolecules. For these cases a more powerful method than groundstate DFT are timedependent DFT (tdDFT) methods related to the Random-Phase Approximation (RPA). All of these methods proceed by looking at the dynamic density-density response function, whose long-ranged properties naturally lead to the weak forces referred to above. In this thesis we have tested these ideas by investigating electronic response and correlation on the predicted properties of spherical atoms. We have developed and tested a variety of approximations to the timedependent response function through approximations of the tdDFT class and a new method involving greater self-consistency in the screening equation, the inhomogenous STLS approach. Through the development of new methods and computer code, we have solved the response equation allowing us to test our approximations on atoms. Calculation of certain dynamic and static properties of a variety of atoms within our approximations generally agree well with known results. In this thesis we have calculated excitation energies of Helium, dipole polarisabilities and C6 van der Waals (vdW) coefficients of a variety of atoms, and groundstate correlation energies Ec of some atoms. The excitation spectra of Helium generated in our new PGG+c approximation are in good agreement with experiment. The dipole polarisabilities are generally in good agreement with known results, with the exception of Magnesium, Beryllium and Sodium. The C6 coefficients are a little poorer with the exception of Helium where they are nearly exact. Correlation energies are generally reasonable in the PGG+c approximation although they are considerably less accurate than the other properties we have calculated for all atoms other than He. The ISTLS correlation energy of Helium is within 5% suggesting that this method may perform well for larger atoms where our present numerical techniques require improvement. These generally positive results suggest that the approximations we have developed may be applied to more complicated systems such as those described above with good results.

description: Now that the properties of low temperature Bose gases at low density, $ρ$, can be examined experimentally it is appropriate to revisit some of the formulas deduced by many authors 4-5 decades ago. One of these is that the leading term in the energy/particle is $2π\hbar^2 ρa/m$, where $a$ is the scattering length. Owing to the delicate and peculiar nature of bosonic correlations, four decades of research have failed to establish this plausible formula rigorously. The only known lower bound for the energy was found by Dyson in 1957, but it was 14 times too small. The correct bound is proved here.

Essays on Political Institutions and Institutional Design

description: This dissertation attempts to understand the factors that determine the performance and choice of political institutions. We start with the recognition that these two aspects of the problem are fundamentally connected given that political institutions are themselves endogenous, i.e. the way in which they perform and function depends importantly on the reasons behind their adoption. Each chapter of this dissertation analyzes a different class of institutions, identifying specific features of the political and social environment that impact their performance and deriving, whenever possible, implications for institutional design. The first chapter studies the main factors that determine the constitutional preferences of citizens over the form of government. We focus on the case of Brazil, where a referendum in 1993 allowed the population to choose between a presidential and a parliamentary system of government. A model is proposed to explain the main facts emerging from the data. It is shown that the parliamentary regime requires a strong system of protection against expropriation, particularly at the local level, and a class of politicians that can be trusted to represent well the interests of voters. We also show that the poor groups of the population are more likely to vote for the presidential regime since the low quality of their local accountability institutions makes them more vulnerable to the expropriation by legislators. The second chapter studies the question of why checks and balances work well in some cases, but not in others. We investigate the conditions under which a system of checks and balances is beneficial to the society. The analysis emphasizes the important role played by political transparency, which is defined as the ability of voters to observe the proposals submitted to congress during the legislative process. We show that transparency is a necessary, but not sufficient, condition for an effective system of checks and balances. The model yields the surprising result that political transparency may be harmful to voters depending on the characteristics of the social and political environment. The third chapter studies a committee decision-making problem with career oriented agents who may be biased towards one of the alternatives. We investigate how the interaction between career concerns and bias affects the behavior of members and how this effect depends on transparency. The main result is that public voting leads to better decisions when the magnitude of the bias is large relative to the common value, while secret voting performs better otherwise. We also show that the interaction between transparency and reputation concerns may exacerbate the biases of incompetent members, leading them to vote more in accordance with their individual interests.

Hereditary topological diagonalizations and the Menger-Hurewicz Conjectures

description: We consider the question, which of the major classes defined by topological diagonalizations of open or Borel covers is hereditary. Many of the classes in the open case are not hereditary already in ZFC, and none of them is provably hereditary. This is contrasted with the Borel case, where some of the classes are provably hereditary. Two of the examples are counter-examples of sizes d$ and b, respectively, to the Menger and Hurewicz Conjectures, and one of them answers a question of Steprans on perfectly meager sets.
QED and relativistic nuclear recoil corrections to the 413 nm tune-out wavelength for the $2\,^3S_1$ state of helium

description: Comparison of high accuracy calculations with precision measurement of the 413 nm tune-out wavelength of the He($2\,^3S_1$) state provides a unique test of quantum electro-dynamic (QED). We perform large-scale relativistic-configuration-interaction (RCI) calculations of the tune-out wavelength, that include the mass-shift operator, and fully account for leading relativistic nuclear recoil terms in the Dirac-Coulomb-Breit (DCB) Hamiltonian. We obtain the QED correction to the tune-out wavelength using perturbation theory, and the effect of finite nuclear size is also evaluated. The resulting tune-out wavelengths for the $2\,^3S_1(M_J=0)$ and $2\,^3S_1(M_J=\pm 1)$ states are 413.084 26(4) nm and 413.090 15(4) nm, respectively. Compared with the only current experimental value of 413.0938(9stat)(20syst) nm for the $2\,^3S_1(M_J=\pm 1)$ state, there is 1.8$σ$ discrepancy between present theoretical work and experiment, which stimulates further theoretical and higher-precision experimental investigations on the 413 nm tune-out wavelength. In addition, we also determine the QED correction for the static dipole polarizability of the He($2\,^3S_1$) state to be 22.5 ppm, which may enable a new test of QED in the future.

description: Given an elliptic curve $E$ in Legendre form $y^2 = x(x - 1)(x - λ)$ over the fraction field of a Henselian ring $R$ of mixed characteristic $(0, 2)$, we present an algorithm for determining a semistable model of $E$ over $R$ which depends only on the valuation of $λ$. We provide several examples along with an easy corollary concerning $2$-torsion.

description: First we identify the free algebras of the class of algebras of binary relations equipped with the composition and domain operations. Elements of the free algebras are pointed labelled finite rooted trees. Then we extend to the analogous case when the signature includes all the Kleene algebra with domain operations; that is, we add union and reflexive transitive closure to the signature. In this second case, elements of the free algebras are 'regular' sets of the trees of the first case. As a corollary, the axioms of domain semirings provide a finite quasiequational axiomatisation of the equational theory of algebras of binary relations for the intermediate signature of composition, union, and domain. Next we note that our regular sets of trees are not closed under complement, but prove that they are closed under intersection. Finally, we prove that under relational semantics the equational validities of Kleene algebras with domain form a decidable set.

description: Basic matrices are defined which provide unique building blocks for the class of normal matrices which include the classes of unitary and Hermitian matrices. Unique builders for quantum logic gates are hence derived since a quantum logic gates is represented by, or is said to be, a unitary matrix. An efficient algorithm for expressing an idempotent as a unique sum of rank $1$ idempotents with increasing initial zeros is derived. This is used to derive a unique form for mixed matrices. A number of (further) applications are given: for example (i) $U$ is a symmetric unitary matrix if and only if it has the form $I-2E$ for a symmetric idempotent $E$, (ii) a formula for the pseudo inverse in terms of basic matrices is derived. Examples for various uses are readily available.
