subject: International finance--Law and legislation

description: This dissertation explores the role of law in the financial development of an emerging economic country. Its main proposition is that law plays a fundamental part in both the construction and the subsequent failure of a financial system, in addition to the function of reducing frictions and distortions in order to maintain the orderly running of the market. The dissertation illustrates the aforementioned proposition with an in-depth case study of the Asian Financial Crisis (AFC) which was initially rooted in the Thai financial sector. Aided by the analytical paradigm offered by Legal Theory of Finance, it parses the legal and institutional aspects of the rapidly developing financial markets in Thailand and her investing partners. This allows the ensuing Crisis to be seen from the previously underexplored institutional underpinning of the volatile financial cycle which characterized the region at the time. Subsequently, the dissertation employs the same intellectual framework in order to explain the post-crisis reform initiatives and their systemic implications for the regional financial architecture under the auspices of the Association of the South East Asian Nations. This dissertation cuts across a number of disciplines: law and finance, law and economic development, financial and banking regulation, international financial law, to name but a few.

description: Abstract: Dosage forms for topical drug delivery systems are applied directly to the skin in order to treat a variety of illnesses. The most recent and widely used drug delivery technology for hydrophobic medications is emulgels. Different polymers are used to prepare emulgel, which serves as both an emulsifying and thickening agent. The gelling capacity reduces surface tension and interfacial tension, increasing the viscosity of the aqueous phase and producing stable emulsions and creams. Emulgels offer significant advantages over both traditional and new vesicular systems when taking into account a number of factors. This formulation, which combines gel and emulsion, is thought to be a novel kind of drug delivery method. Emulgel is a highly promising product for use in dermatology since it is translucent, has an exquisite appearance, is greaseless, readily removed, easily spreadable, emollient, non-staining, and has a longer shelf life. It also has less potential to cause major adverse effects.

description: We demonstrate the possibility to rectify the nanoscale radiative heat flux between two nanoparticles by coupling them with the nonreciprocal surface modes of a magneto-optical substrate in a Voigt configuration. When the non-reciprocal medium supports a surface wave in the spectral window where heat exchanges take place the rectification coefficient can reach large values opening so the way to the design of true thermal diodes.

description: Let $X$ be a projective curve of genus 2 over an algebraically closed field of characteristic 2. The Frobenius map on X induces a rational map on the moduli space of rank-2 bundles. We show that up to isomorphism, there is only one (up to tensoring by an order two line bundle) semi-stable vector bundle of rank 2 with determinant equal to a theta characteristic whose Frobenius pull-back is not stable. The indeterminacy of the Frobenius map at this point can be resolved by introducing Higgs bundles.

description: Quasi-one-dimensional (Q1D) Cr-based pnictide K$_2$Cr$_3$As$_3$ has aroused great research interest due to its possible triplet superconducting pairing symmetry. Recent experiments have shown that incorporating hydrogen atoms into K$_2$Cr$_3$As$_3$ would significantly change its electronic and magnetic properties. Hence, it's necessary to investigate the impact of hydrogen doping in superconducting pairing symmetry of this material. Employing the hydrogen as an non-trivial electron-doping, our calculates show that, different from the $p_z$-wave obtained without hydrogen, the system exhibits $p_x\pm ip_y$ pairing superconductivity under specific hydrogen doping. Specifically, we adopt the random-phase-approximation approach based on a six-band tight-binding model equipped with multi-orbital Hubbard interactions to study the hydrogen-doping dependence of the pairing symmetry and superconducting $T_c$. Under the rigid-band approximation, our pairing phase diagram shows the spin-triplet pairing states is dominated through out the hydrogen-doping regime $x\in (0,0.7)$. Particularly, the $T_c\sim x$ curve shows a peak at the 3D-quasi-1D Lifshitz transition point, and the pairing symmetry around this doping level is $p_x\pm ip_y$. The physical origin of this pairing symmetry is that the density of states is mainly concentrated at $k_x(k_y)$ with large momentum. Due to the three-dimensional character of the real material, this $p_x\pm ip_y$-wave superconducting state possesses point gap nodes. We further provide experiment prediction to identify this triplet $p_x\pm ip_y$-wave superconductivity.

description: A number of authors have in recent years proposed that the processes of macroevolution may give rise to self-organized critical phenomena which could have a significant effect on the dynamics of ecosystems. In particular it has been suggested that mass extinction may arise through a purely biotic mechanism as the result of so-called coevolutionary avalanches. In this paper we first explore the empirical evidence which has been put forward in favor of this conclusion. The data center principally around the existence of power-law functional forms in the distribution of the sizes of extinction events and other quantities. We then propose a new mathematical model of mass extinction which does not rely on coevolutionary effects and in which extinction is caused entirely by the action of environmental stresses on species. In combination with a simple model of species adaptation we show that this process can account for all the observed data without the need to invoke coevolution and critical processes. The model also makes some independent predictions, such as the existence of ``aftershock'' extinctions in the aftermath of large mass extinction events, which should in theory be testable against the fossil record.

description: In this paper we study actions of locally compact quantum groups on von Neumann algebras and prove that every action has a canonical unitary implementation, paralleling Haagerup's classical result on the unitary implementation of a locally compact group action. This result is an important tool in the study of quantum groups in action. We will use it in this paper to study subfactors and inclusions of von Neumann algebras. When alpha is an action of a locally compact quantum group on the von Neumann algebra N we can give necessary and sufficient conditions under which the inclusion of the fixed point algebra in the algebra N in the crossed product, is a basic construction. When alpha is an outer and integrable action on a factor N we prove that the inclusion of the fixed point algebra in the algebra N is irreducible, of depth 2 and regular, giving a converse to the results of Enock and Nest. Finally we prove the equivalence of minimal and outer actions and we generalize a theorem of Yamanouchi: every integrable outer action with infinite fixed point algebra is a dual action.

description: Classical constraints on the reduced density matrix of quantum fluids in a single Landau level, termed as local exclusion conditions (LECs) [B. Yang, arXiv:1901.00047], have recently been shown to characterize the ground state of many FQH phases. In this work, we extend the LEC construction to build the elementary excitations, namely quasiholes and quasielectrons, of these FQH phases. In particular, we elucidate the quasihole counting, categorize various types of quasielectrons, and construct their microscopic wave functions. Our extensive numerical calculations indicate that the undressed quasielectron excitations of the Laughlin state obtained from LECs are topologically equivalent to those obtained from the composite fermion theory. Intriguingly, the LEC construction unveils interesting connections between different FQH phases and offers a novel perspective on exotic states such as the Gaffnian and the Fibonacci state.

description: High-contrast observations with JWST can reveal key composition and vertical mixing dependent absorption features in the spectra of directly imaged planets across the 3-5 $μ$m wavelength range. We present novel coronagraphic images of the HR 8799 and 51 Eri planetary systems using the NIRCam Long Wavelength Bar in an offset "narrow" position. These observations have revealed the four known gas giant planets encircling HR 8799, even at spatial separations challenging for a 6.5 m telescope in the mid-infrared, including the first ever detection of HR 8799 e at 4.6 $μ$m. The chosen filters constrain the strength of CO, CH4, and CO2 absorption in each planet's photosphere. The planets display a diversity of 3-5 $μ$m colors that could be due to differences in composition and ultimately be used to trace their formation history. They also show stronger CO2 absorption than expected from solar metallicity models, indicating that they are metal enriched. We detected 51 Eri b at 4.1 $μ$m and not at longer wavelengths, which, given the planet's temperature, is indicative of out-of-equilibrium carbon chemistry and an enhanced metallicity. Updated orbits fit to the new measurement of 51 Eri b validate previous studies that find a preference for high eccentricities ($e{=}0.57_{-0.09}^{+0.03}$), which likely indicates some dynamical processing in the system's past. These results present an exciting opportunity to model the atmospheres and formation histories of these planets in more detail in the near future, and are complementary to future higher-resolution, continuum-subtracted JWST spectroscopy.

Similar to high-order statistics, the low-order relative scaling exponents exhibit unambiguous departures from the Kolmogorov 1941 theory and agree well with existing multiscaling models. No transition from normal scaling to anomalous scaling is observed.

description: Coral reefs are one of the most diverse and complex ecosystems on the planet and provide incomes, food, and important ecosystem services for hundreds of millions of people. However, reefs are in global decline and are changing from highly diverse and topographically complex ecosystems dominated by coral species to species-poor and structurally simple ecosystems dominated by macroalgae. The reason of this decline is complex but can be attributed to multiple local stressors such as overfishing, marine pollution and declining water quality, and global stressors such as global warming and ocean acidification product of anthropogenic activities. Corals and algae compete intensely for space, light and nutrients in coral reefs, and this competition is a structuring and shaping process which determines the abundance of both groups of species. Therefore, the general aim of this thesis is to explore experimentally and descriptively the dynamics between corals and macroalgae in coral reefs from three approaches. The first approach focuses on the temporal variability of coral-algal interaction and its implications for coral mortality in different reef habitats. The second study explores the spatial variability of coral-algal interactions and coral health at the local and regional scales within a terrestrial gradient of influence. The third study addresses the potential effects of ocean acidification on competitive mechanisms utilised by algae during coral-algal competition and explores coral-algal competitive outcomes under different levels of ocean acidification. This study was carried out in Heron Island and Keppel Islands, in the southern Great Barrier Reef, Australia.

description: Due to the progressive increase in size of the latest Cherenkov-type detectors, it is becoming increasingly important to design a suitable compensation system based on coils of the Earth's magnetic field to ensure the correct operation of the photomultipliers (PMTs). Until now, most studies have assessed the correct functioning of such a system by the proportion of PMTs experiencing more than 100 mG of magnetic field perpendicular to their axis. In the present study, we discuss whether this evaluation parameter is the most appropriate and propose the average residual perpendicular magnetic field $$ as an alternative that more closely reflects the loss of detection efficiency of PMTs. A compensation system design is also proposed that offers good results as well as being economical to optimise this parameter.

Full family of flattening solitary waves for the mass critical generalized KdV equation

description: For the mass critical generalized KdV equation $\partial_t u + \partial_x (\partial_x^2 u + u^5)=0$ on $\mathbb R$, we construct a full family of flattening solitary wave solutions. Let $Q$ be the unique even positive solution of $Q''+Q^5=Q$. For any $ν\in (0,\frac 13)$, there exist global (for $t\geq 0$) solutions of the equation with the asymptotic behavior \begin{equation*} u(t,x)= t^{-\fracν2} Q\left(t^{-ν} (x-x(t))\right)+w(t,x) \end{equation*} where, for some $c>0$, \begin{equation*} x(t)\sim c t^{1-2ν} \quad \mbox{and}\quad \|w(t)\|_{H^1(x>\frac 12 x(t))} \to 0\quad \mbox{as $t\to +\infty$.} \end{equation*} Moreover, the initial data for such solutions can be taken arbitrarily close to a solitary wave in the energy space. The long-time flattening of the solitary wave is forced by a slowly decaying tail in the initial data. This result and its proof are inspired and complement recent blow-up results for the critical generalized KdV equation. This article is also motivated by previous constructions of exotic behaviors close to solitons for other nonlinear dispersive equations such as the energy-critical wave equation.

Theoretical cosmology

description: The concept of an Isotropic (Past) Singularity (IPS) was defined by Goode and Wainwright in 1985 as a mathematical formalisation of quiescent cosmology and the Weyl Curvature Hypothesis (WCH) for the isotropic initial state of the universe. ¶ In this thesis it is argued that the framework of an IPS is not sufficient to guarantee a future behaviour which is compatible with the future anisotropy implied by quiescent cosmology and the WCH. Therefore it is necessary to complete and combine the framework of an IPS with new definitions, in order to assure an appropriate past and future behaviour of a cosmology satisfying the respective combination of definitions. Since it is not yet clear whether our universe will expand indefinitely or recontract, it is reasonable to provide a new definition for the scenario of an ever expanding cosmos and one for a recollapsing universe. ¶ Specific example space-times are explored for their conformal structure, future evolution and compatibility with the WCH as guidance in the quest for the new definitions. Motivated by these particular models, we present for the first time the definitions for the conformal structure of an Anisotropic Future Endless Universe (AFEU) and an Anisotropic Future Singularity (AFS). For the purpose of completeness and comparison, we furthermore define the physically less realistic Isotropic Future Singularity (IFS) and the Future Isotropic Universe (FIU). ¶ A number of essential technical implications of the new de nitions are derived. It is explicitly shown that a conformal structure, whose conformal factor is a function of cosmic time, necessarily leads to an asymptotically Ricci dominated Weyl curvature and asymptotically expansion dominated kinematics, if the conformal metric remains regular. This condition is satis ed by the IFS and FIU. Based on this, it is argued that a conformal structure for an anisotropic nal state of the universe requires a degenerate conformal metric, as is the case for the AFS and AFEU. ¶ This degeneracy complicates the derivation of physical attributes of the concepts of an AFEU and an AFS and, consequently, new approaches are unavoidable. Some physical properties are examined, such as the behaviour of the expansion scalar and the curvature. It is proven that the conformal space-times always possess a future singularity, which under reasonable assumptions corresponds to a strong curvature singularity. Finally, we reveal sufficient conditions for the AFS, as well as the IPS, to be a strong curvature singularity. ¶ The combination of the IPS with the AFEU and the AFS could provide a possible first version of a complete mathematical formalisation of quiescent cosmology.

Bose-Einstein condensation

description: Research into Bose-Einstein condensates is currently a thriving field in physics. Much of the experimental research involves the detection of cold atom clouds under various conditions. Consequently, the fundamental and technical limitations of the imaging techniques and technologies utilized will have a dramatic influence on the results of these experiments. Therefore a detailed analysis of the restrictions on a Bose-Einstein condensate imaging system is overdue and will facilitate further developments in the field due to an increase in the signal to noise ratio; hence a greater level of detail available in experimental images. ¶ The work carried out in this thesis focuses on the properties of absorption imaging techniques, in the quest for an optimized imaging system. Optimization was proposed to be achieved through maximization of the signal to noise ratio by any and all means available. A detailed investigation of the diverse influences on the signal to noise ratio was performed with a focus on eliminating technical restrictions and minimizing fundamental constraints. By studying a 2f - absorption imaging system the maximal signal to noise ratio of 35 was calculated. This corresponded to imaging a cloud of 105 87Rb atoms in a (50 micron) square box with a 31.8MHz detuned, 780nm laser at an intensity of 570W/(m.m) for 35 micro-s. These optimal imaging parameters correspond to our imaging system being limited by the well depth of our detector, not by a fundamental physical process. Furthermore, current experimental noise is identified as the most significant inhibitor to the achievement of an optimized absorption image. ¶ This study represents a first analysis of the quality of current Bose-Einstein condensate imaging techniques and limitations.

description: This dissertation explores and reflects on the professional practice of the author and a group of five experts through case studies. Incorporating interviews, observations, reflective journals, video footage, and a choral project, this research aims to explore how five expert choral conductors work in the rehearsal setting. Rehearsal techniques are as diverse as the individuals who practise them. Yet, even though conductors have their differences, the varied outcomes can still be judged as satisfactory. These techniques are not necessarily skills that have been taught in an undergraduate conducting class. Conducting courses and textbooks focus on beat patterns and other skills that must be mastered by the novice and which, in turn, lend themselves more readily to assessment. However, the running of a rehearsal is a complex mixture of musicianship and teaching skills that are continually developed over a lifetime of practice. The following questions emerge: how, then, do highly successful conductors work in rehearsal? What do they consider to be important parts of their own practice? What skills and attributes are crucial for successful ensemble leadership? For this research, five expert choral conductors were observed on site in multiple rehearsals and in working with a variety of vocal ensembles. They also participated in a wide-ranging, semistructured interview that further explored their approaches to conducting, repertoire selection, planning, personal philosophy, and reflections on their craft. The author used the data generated from the case studies and through a survey of core literature to experiment with their own practice during a 12-week rehearsal period that culminated in a performance of Haydn’s Missa in angustiis. The research project revealed that, while each case study conductor had an individualistic approach to their rehearsal delivery, five main characteristics appeared to be common amongst them all: they recognised the conductor’s role as a teacher; they were interested in working towards a sound ideal; they believed in their responsibility to develop skills; they included performance opportunities in the rehearsal setting; and they emphasised the importance of building community. As a result, these concepts formed the foundation of the author’s work with their own ensemble. These findings have implications for the author’s own practice as well as broader implications for other conductors and the training of student conductors. The results appear to advocate a more holistic approach to conducting and conductor training as well as the importance of developing community within the avocational choir.

description: We present a comprehensive analysis of the exact Bethe ansatz solution for the onedimensional spinor Bose gas. The Bethe ansatz equations and the thermodynamic Bethe ansatz equations are derived, before investigating properties of these equations in limiting regimes. We explore the difference between spinless and spinor particles in the onedimensional Bose gas. For the spinor Bose gas, we present a new approximation to the thermodynamic Bethe ansatz equations which allows them to be solved in the strong coupling regime. We derive the first order correction to the solutions of the thermodynamic Bethe ansatz equations in a low temperature regime, where spin effects are most evident. We then derive thermodynamic quantities for this model, adding a first order correction to the thermodynamics of the spinless system. ¶ The subject of fractional exclusion statistics is presented, and its significance with regards to the spinless Bose gas is discussed. We also discuss its significance with regards to the spinor Bose gas, and find a regime in which non-mutual statistics may be applied to the spinor Bose gas to obtain expansions of thermodynamic quantities. These expressions are seen to improve upon previous analytical results for the model.

Thermal interdiffusion

description: An investigation into the effects of thermal interdiffusion on the characteristics of quantum dot infrared photodetectors (QDIPs) yields results useful for the creation of a two-colour QDIP. For high temperature rapid thermal annealing, quantum dot interdiffusion is induced, resulting in a large wavelength redshift in the photodetector spectral response, at the cost of a small degradation in device performance. The evaluation of a two-colour QDIP fabricated using selective suppression of interdiffusion during thermal annealing shows uniform performance in the two different detector pixels. This has implications as a useful process for the future fabrication of multi-colour QDIPs.

description: We study the statistical mechanics of random surfaces generated by NxN one-matrix integrals over anti-commuting variables. These Grassmann-valued matrix models are shown to be equivalent to NxN unitary versions of generalized Penner matrix models. We explicitly solve for the combinatorics of 't Hooft diagrams of the matrix integral and develop an orthogonal polynomial formulation of the statistical theory. An examination of the large N and double scaling limits of the theory shows that the genus expansion is a Borel summable alternating series which otherwise coincides with two-dimensional quantum gravity in the continuum limit. We demonstrate that the partition functions of these matrix models belong to the relativistic Toda chain integrable hierarchy. The corresponding string equations and Virasoro constraints are derived and used to analyse the generalized KdV flow structure of the continuum limit.

Towards a definition of a meteor cluster: Detection of meteor clusters from meteor orbit databases

description: As of today, there is no official definition of a meteor cluster. It is usually identified as a large number of meteors sharing a similar radiant and velocity, all occurring within a few seconds. Only eight clusters have been reported so far, from single-camera or camera network observations. We aim to provide an overview of meteor clusters to help define what constitutes a cluster by potentially adding more to the already identified ones and determining their common parameters. A search for new clusters is performed in publicly available International Astronomical Union meteor databases with the DBSCAN algorithm. Then, a statistical significance method is applied to derive the most promising cluster candidates. However, the method still lacks a way to debias the atmospheric area surveyed by the cameras due to a lack of publicly available data. A set of 16 statistically significant potential clusters is identified, involving 4 to 7 fragments. The 90th percentile includes a duration of 8 seconds, a velocity difference of 2.2 km/s, and a radiant spread of nearly 4 degrees. The velocity difference may arise from the method used for orbit computation. Meteor clusters might be more frequent than currently reported. However, we recommend that future meteor orbit databases also include a way to estimate the surveyed area by the cameras involved in the detection. This would strengthen the veracity of the 16 identified cluster candidates and ultimately allow scientists to fully debias the number of clusters, and hence derive the physical lifetime expectancy of meteoroids, which is often overlooked due to the focus on collisional lifetime estimates only. We also recommend that any future cluster observation report includes the expected number of random occurrences and consider the event to be real if this value is below 0.1.

description: Quantum key distribution is the first major area of quantum information science to find practical use outside of its field. Quantum key distribution involves transmitting cryptographic keys using quantum states. Any attempt to eavesdrop on the transmission will, necessarily by the laws of quantum mechanics, disturb or destroy the states. By identifying and only using keys that have not been disturbed, a perfectly secure cryptographic system can be realised. ¶ Discrete variable quantum key distribution was proposed in 1984. Since then attempts to exploit this technology have been beset with the difficulties of working with the discrete variables in question—single photon states. In the late 90’s the idea of continuous variable quantum key distribution was developed, in which the key-carrying quantum information states are properties of a bright, continuous wave laser beam. Bright laser beams are relatively simple to manipulate and can carry large amounts of information even when subject to high loss. ‘Broadband’ continuous variable quantum key distribution refers to the large information rates obtainable by using broad laser modulation sidebands. ¶ In 2005 the ANU Quantum Optics group published an experimental demonstration of broadband continuous variable quantum key distribution. This thesis documents the project work undertaken to rebuild an improved version of this experiment, and also the work undertaken to prepare for more advanced experiments. The main goal of the improved experiment was to increase the key distribution rate, while the advanced experiments were directed towards practical implementation of the system in optical fibre. ¶ The experiment rebuild was achieved with most improvements for higher bandwidth successfully implemented. Some improvements were unplanned, being necessitated by problems with the initial improvements. Although preliminary experimental data was acquired, time constraints precluded a successful cryptographic key distribution. Pilot design and major purchasing for future experiments was also completed.
From Ideals to Implementation: Explaining the Global Transition to Universal Health Coverage

description: The world is witnessing a groundbreaking transition to universal health coverage. Yet few researchers have explained why nations as distinct as Rwanda and Thailand, for example, have chosen to implement universal coverage within the last decade or so. An analysis of international politics can help illuminate why the idea that everyone has a right to health has materialized into concrete health policies. This paper argues that both international norm construction and domestic conditions of individual states influence whether or not countries adopt universal health coverage. As a principle norm creator and agenda setter, the World Health Organization’s (WHO) pragmatic, evidence-based framing of universal coverage has enabled it to make a strong argument for UHC. Rather than characterize the WHO as the sole determinant of the transition to UHC, this paper asserts that it serves a catalytic role in shaping countries’ decisions to reform their health systems—global and local limitations also constrain its mandate. National governments have unique economic and political conditions that work to enable or disable policy change. Thus, the powerful convergence of effective norm construction in international networks and greater local capacity has encouraged countries across the globe to reform their health systems.
Equilibration on average in quantum processes with finite temporal resolution

description: We characterize the conditions under which a multi-time quantum process with a finite temporal resolution can be approximately described by an equilibrium one. By providing a generalization of the notion of equilibration on average, where a system remains closed to a fixed equilibrium for most times, to one which can be operationally assessed at multiple times, we place an upper-bound on a new observable distinguishability measure comparing a multi-time process with a finite temporal resolution against a fixed equilibrium one. While the same conditions on single-time equilibration, such as a large occupation of energy levels in the initial state remain necessary, we obtain genuine multi-time contributions depending on the temporal resolution of the process and the amount of disturbance of the observer's operations on it.

description: We prove maximal regularity results in Hölder and Zygmund spaces for linear stationary and evolution equations driven by a large class of differential and pseudo-differential operators L, both in finite and in infinite dimension. The assumptions are given in terms of the semigroup generated by L. We cover the cases of fractional Laplacians and Ornstein-Uhlenbeck operators with fractional diffusion in finite dimension, and several types of local and nonlocal Ornstein-Uhlenbeck operators, as well as the Gross Laplacian and its negative powers, in infinite dimension.
A Model for Multi-Agent Autonomy That Uses Opinion Dynamics and Multi-Objective Behavior Optimization

description: This paper reports a new hierarchical architecture for modeling autonomous multi-robot systems (MRSs): a nonlinear dynamical opinion process is used to model high-level group choice, and multi-objective behavior optimization is used to model individual decisions. Using previously reported theoretical results, we show it is possible to design the behavior of the MRS by the selection of a relatively small set of parameters. The resulting behavior - both collective actions and individual actions - can be understood intuitively. The approach is entirely decentralized and the communication cost scales by the number of group options, not agents. We demonstrated the effectiveness of this approach using a hypothetical `explore-exploit-migrate' scenario in a two hour field demonstration with eight unmanned surface vessels (USVs). The results from our preliminary field experiment show the collective behavior is robust even with time-varying network topology and agent dropouts.
