description: Biological regulatory networks depend upon chemical interactions to process information. Engineering such molecular computing systems is a major challenge for synthetic biology and related fields. The chemical reaction network (CRN) model idealizes chemical interactions, allowing rigorous reasoning about the computational power of chemical kinetics. Here we focus on function computation with CRNs, where we think of the initial concentrations of some species as the input and the equilibrium concentration of another species as the output. Specifically, we are concerned with CRNs that are rate-independent (the computation must be correct independent of the reaction rate law) and composable ($f\circ g$ can be computed by concatenating the CRNs computing $f$ and $g$). Rate independence and composability are important engineering desiderata, permitting implementations that violate mass-action kinetics, or even "well-mixedness", and allowing the systematic construction of complex computation via modular design. We show that to construct composable rate-independent CRNs, it is necessary and sufficient to ensure that the output species of a module is not a reactant in any reaction within the module. We then exactly characterize the functions computable by such CRNs as superadditive, positive-continuous, and piecewise rational linear. Thus composability severely limits rate-independent computation unless more sophisticated input/output encodings are used.

description: We prove the non-integrability (non-existence of additional analytic conserved quantities other than Hamiltonian) for Fermi-Pasta-Ulam (FPU) lattices by virtue of Lyapunov-Kovalevskaya- -Ziglin-Yoshida's monodromy method about the variational equations. The key to this analysis is that the normal variational equations along a certain solution happen to be in a type of Lamé equations. We also introduce the classification problem towards non-homogeneous nonlinear lattices including FPU lattices using non-integrability preserving transformation.

description: The behaviour of electrons in nanostructures such as quantum wells is of interest for the design of new electronic and electro-optic devices, and also for exploration of basic many-body physics. This thesis develops and tests improved methods for describing such electronic behaviour. The system used for this work was the parabolic quantum well (PQW), an important special system which has recently attracted much experimental and theoretical attention. We firstly report self-consistent nonlinear groundstate solutions of the Poisson equation together with the Thomas-Fermi (TF) hydrostatic equations. In contrast to most previous solutions, all the electron density profiles were inhomogeneous and continuous. We also added a von Weizsacker term with and without the exchange/exchange-correlation to the above treatment, using a novel numerical approach allowing for wider electron gases than previously possible. We also report for the first time the effects of spatially varying effective mass and dielectric function in theories of this type. To investigate infrared response of these systems, we apply new hydrodynamic theories recently proposed by Dobson. By using this type of theory, we simultaneously satisfy the Harmonic Potential Theorem (extended generalized Kohn theorem) and obtain the correct 2D plasmon dispersion, as well as obtaining the correct spacing of standing plasmons. Other inhomogeneous hydrodynamic theories do not achieve this. We also showed analytically an exact solution for a plasmon mode at the Kohn frequency in addition to one found in the Harmonic Potential Theorem. An open hydrodynamic theory was then developed based on this type of mode. Numerical application of Kohn Frequency Theorem theory was shown and the results were compared with other existing hydrodynamic theories.

Essays on Institutional Investors

Year: 2013
Subjects: Finance

description: This dissertation analyzes the role of institutional investors in capital markets. The first essay studies what affect mutual fund decisions on hiring and firing sub-advisors and the ex-post effects. We show that deterioration in mutual fund performance or increase in outflows predicts a higher propensity of a fund to change its sub-advisors. However, mutual funds continue to underperform by about 1% in the 18-months after a change in sub-advisor, even after controlling for fund category, past returns and past flows. The continuing underperformance of mutual funds can be attributed to decreasing returns for sub-advisors in deploying their ability as suggested in Berk and Green (2004). The second essay provides empirical analysis on hedge fund exposures to overpriced real estate assets. Consistent with models in which delegated portfolio managers may want to invest in overpriced assets, I find that hedge funds were holding real estate stocks instead of selling short during the period of overpricing (2003Q1-2007Q2). The third essay finds that investor composition affect fund managers' portfolio choices. Specifically, I show that retail-oriented hedge funds invested more in overpriced real estate assets than institution-oriented hedge funds.

description: This dissertation focuses on institutional investors in corporate bond markets and their impacts on the underlying corporate bonds. The dissertation is composed of three chapters. The first chapter studies how information networks of corporate bond mutual funds may be constructed. It highlights how information flow between corporate bond mutual funds affects fund performance, herding behaviors, and the underlying corporate bond market. By examining the trading behavior of corporate bond mutual funds, I show that bond funds in more central positions of a trading network have an informational advantage that results in 0.33% higher future fund risk-adjusted return. This positive relationship becomes stronger during periods of high market uncertainty and for bond funds with more liquid assets as they can respond to the information signal with a lower asset reallocation cost. I further show that manager turnover, ranking pressure, and fund flow fluctuation drive within-fund time varying changes in network centrality. The second chapter exploits the influence of information networks of corporate bond mutual funds on their underlying corporate bonds. I show that corporate bonds owned by highly network-central bond funds increase underlying liquidity, leading to a 3.5% decrease in future bid/ask spreads and a lower Amihud illiquidity measure. This is hypothesized to occur due to increased information efficiency, which allows for more bond specific information to be reflected in the price, and intensified herding behavior. Moreover, I construct a network to represent herding behavior by following the same trades across quarters. A 0.3% decrease in risk-adjusted fund return is found for bond funds that have the strongest herding behavior. The third chapter studies how corporate bond exchange-traded funds (ETF) impact the underlying corporate bond return comovement and how it relates to trading and arbitrage activities of corporate bond ETFs. The literature is silence about the effect of corporate bond ETFs on the comovement of underlying bond securities. This chapter aims to fill this gap by providing the first empirical evidence of bond return comovement driven by bond ETFs ownership. I find that bond ownership by corporate bond ETFs leads to higher bond return comovement, an increase of 0.26 in the beta of corporate bond return with respect to the aggregate bond portfolio. In contrast, bond ownership by other traditional institutional investors in the corporate bond market like bond mutual funds and insurance companies do not contribute to corporate bond return comovement. Furthermore, this chapter highlights that return comovement is driven by corporate bond ETFs’ creation and redemption activities.

description: We develop a theoretical and computational framework to study polarons in semiconductors and insulators from first principles. Our approach provides the formation energy, excitation energy, and wavefunction of both electron and hole polarons, and takes into account the coupling of the electron or hole to all phonons. An important feature of the present method is that it does not require supercell calculations, and relies exclusively on electron band structures, phonon dispersions, and electron-phonon matrix elements obtained from calculations in the crystal unit cell. Starting from the Kohn-Sham (KS) equations of density-functional theory, we formulate the polaron problem as a variational minimization, and we obtain a nonlinear eigenvalue problem in the basis of KS states and phonon eigenmodes. In our formalism the electronic component of the polaron is expressed as a coherent superposition of KS states, in close analogy with the solution of the Bethe-Salpeter equation for the calculation of excitons. We demonstrate the power of the methodology by studying polarons in LiF and Li2O2. We show that our method describes both small and large polarons, and seamlessly captures Frohlich-type polar electron-phonon coupling and non-Frohlich coupling to acoustic and optical phonons. To analyze in quantitative terms the electron-phonon coupling mechanisms leading to the formation of polarons, we introduce spectral decompositions similar to the Eliashberg spectral function. We validate our theory using both analytical results and direct calculations on large supercells. This study constitutes a first step toward complete ab initio many-body calculations of polarons in real materials.

description: Procedural content generation via machine learning (PCGML) in games involves using machine learning techniques to create game content such as maps and levels. 2D tile-based game levels have consistently served as a standard dataset for PCGML because they are a simplified version of game levels while maintaining the specific constraints typical of games, such as being solvable. In this work, we highlight the unique characteristics of game levels, including their structured discrete data nature, the local and global constraints inherent in the games, and the sensitivity of the game levels to small changes in input. We define the robustness of data as a measure of sensitivity to small changes in input that cause a change in output, and we use this measure to analyze and compare these levels to state-of-the-art machine learning datasets, showcasing the subtle differences in their nature. We also constructed a large dataset from four games inspired by popular classic tile-based games that showcase these characteristics and address the challenge of sparse data in PCGML by providing a significantly larger dataset than those currently available.

description: Influence maximization, adaptive routing, and dynamic spectrum allocation all require choosing the right action from a large set of alternatives. Thanks to the advances in combinatorial optimization, these and many similar problems can be efficiently solved given an environment with known stochasticity. In this paper, we take this one step further and focus on combinatorial optimization in unknown environments. We consider a very general learning framework called combinatorial multi-armed bandit with probabilistically triggered arms and a very powerful Bayesian algorithm called Combinatorial Thompson Sampling (CTS). Under the semi-bandit feedback model and assuming access to an oracle without knowing the expected base arm outcomes beforehand, we show that when the expected reward is Lipschitz continuous in the expected base arm outcomes CTS achieves $O(\sum_{i =1}^m\log T/(p_iΔ_i))$ regret and $O(\max\{\mathbb{E}[m\sqrt{T\log T/p^*}],\mathbb{E}[m^2/p^*]\})$ Bayesian regret, where $m$ denotes the number of base arms, $p_i$ and $Δ_i$ denote the minimum non-zero triggering probability and the minimum suboptimality gap of base arm $i$ respectively, $T$ denotes the time horizon, and $p^*$ denotes the overall minimum non-zero triggering probability. We also show that when the expected reward satisfies the triggering probability modulated Lipschitz continuity, CTS achieves $O(\max\{m\sqrt{T\log T},m^2\})$ Bayesian regret, and when triggering probabilities are non-zero for all base arms, CTS achieves $O(1/p^*\log(1/p^*))$ regret independent of the time horizon. Finally, we numerically compare CTS with algorithms based on upper confidence bounds in several networking problems and show that CTS outperforms these algorithms by at least an order of magnitude in majority of the cases.

description: In today's globalized society, financial aid for health is not only an obligation, but also a necessity to safeguard public health. Although efforts began long before the organization of the United Nations and later the targeted actions of the World Health Organization, a strong increase in DAH has been identified since our entry into the last millennium. Clearly, the development of new treatments and the use of financial tools have influenced this increase, but the rapid spread of communicable diseases that have been a direct threat to global health cannot be overlooked. Mainly, from 1990 onwards we have very detailed data on disease trends, reference indicators in the general population, as well as on the amount of financial assistance with detailed reports as to the scope of health operations (development of infrastructures, provision of drugs, educational programs, prophylaxis, etc.). In this study the Central African Republic is examined, one of the poorest countries in the world with an extremely low health budget. Without taking for granted the extent to which health indicators are influenced by health operations financing, the correlation between health indicators and financing amounts is highlighted.

description: Non-Hermitian exceptional points (EPs) represent a special type of degeneracy where not only the eigenvalues coalesce, but also the eigenstates tend to collapse on each other. Recent studies have shown that in the presence of an EP, light-matter interactions are profoundly modified, leading to a host of novel optical phenomena ranging from enhanced sensitivity to chiral light transport. As of now, however, in order to stabilize a system at the vicinity of an exceptional point, its related parameters must be carefully tuned and/or continuously controlled. To overcome this limitation, here we introduce a new family of broadband exceptional points based on unidirectional coupling, implemented by incorporating an Sshaped waveguide in a microring cavity. In active settings, the resulting unidirectionality exhibits unprecedented resilience to perturbations, thus providing a robust and tunable approach for directly generating beams with distinct orbital angular momentum (OAM). This work could open up new possibilities for manipulating OAM degrees of freedom in applications pertaining to telecommunications and quantum computing, while at the same time may expand the notions of non-Hermiticity in the orbital angular momentum space.

description: Bio-inspired oscillatory foil propulsion has the ability to traverse various propulsive modes by dynamically changing the foil's heave and pitch kinematics. This research characterizes the propulsion properties and wake dynamics of a symmetric oscillating foil, specifically targeting the high Reynolds number operation of small to medium surface vessels whose propulsive specifications have a broad range of loads and speeds. An unsteady Reynolds-averaged Navier-Stokes (URANS) solver with a k-$ω$ SST turbulence model is used to sweep through pitch amplitude and frequency at two heave amplitudes of $h_0/c=1$ and $h_0/c=2$ at $Re=10^6$. At $h_0/c=2$, the maximum thrust coefficient is $C_T=8.2$ due to the large intercepted flow area of the foil, whereas at a decreased Strouhal number the thrust coefficient decreases and the maximum propulsive efficiency reaches 75%. Results illustrate the kinematics required to transition between the high-efficiency and high-thrust regimes at high Reynolds number and the resulting changes to the vortex wake structure. The unsteady vortex dynamics throughout the heave-pitch cycle strongly influence the characterization of thrust and propulsive efficiency, and are classified into flow regimes based on performance and vortex structure.

description: An approach to predictions of position and size of hydrate plugs inside gas wells has been proposed. It is based on the mathematical model of steady non-isothermal flow of real gas in tubes and an algorithm of calculation of equilibrium conditions of hydrate formation. The proposed approach includes the following steps. 1) Numerically solve the system of ordinary differential equations to find the distributions of pressure and temperature along a particular well. 2) Represent the results of calculations as connection between pressure and temperature. 3) Find the intersection of this function with the calculated or experimental equilibrium curve for a particular natural gas. 4) Find the depth of well from the results of numerical solution.

description: Herein, a transparent and reproducible substrate, fabricated using polydimethylsiloxane (PDMS) laminated with self-assembled Ag nanoparticles (Ag NPs), was employed as a universal surface-enhanced Raman scattering (SERS) substrate for the detection of targets with various matrices. The Ag NPs were assembled in a two-dimensional manner via a self-assembly technique. Due to the electrostatic interaction between the Ag NPs, the reproducibility of the assembly was ensured by the fixed density of the assembled Ag NPs at saturated assembly states. The assembled pattern and plasmon resonance of the Ag NPs were well preserved during the molding and curing of PDMS. As a result, the Ag NP laminated PDMS film exhibited a SERS effect to the adsorbed p-aminothiophenol comparable to that of the assembled Ag NPs on a glass slide. Extra SERS enhancement was achieved by construction of a Ag (PDMS)/molecule/Ag (glass) configuration due to the electromagnetic coupling between the Ag NPs. The Raman scattering of 4-mercaptobenzoic acid and benzotriazole modified on the surfaces of a smooth Au electrode and copper foil, respectively, was detected with the aid of the Ag NP-laminated PDMS film. Furthermore, malachite green dispersed in a KBr solid matrix was quantitatively determined with a detection limit of 0.5 μg/g. It is suggested that the SERS enhancement and consequential SERS detection sensitivity of the target molecules may be further maximized by adjusting the distance between the target molecules and the Ag NPs laminated on the PDMS film.
Scrolling Down One's Life: The Importance of Information and Communication Technologies for the (forced) Migrants in Greece

Publisher: name: University of Leicester
Year: 2021

description: Situated in the field of digital migration studies, the thesis adds to emerging research on the terrain of 'the everyday' in relation to migration and ICT use. Specifically, it examines the importance of Information and Communication Technologies in the lives of the (forced) migrants who arrived in Greece after the border crisis of 2015 and role of self-organised groups as (communication) proxies to them. Through a multi-sited ethnographic approach, the thesis explored how (forced) migrants constructed their everyday realities in a Housing Squat, a Refugee Camp and an Immigration Detention Centre, the role played by ICTs in a context of liminality and the factors affecting their access to and use of such technologies. Theoretically, the project draws upon the work of Agamben (2005) on the State of Exception, Foucault’s (1986) concept of Heterotopias and De Certeau’s (1988) theory of the Practice of Everyday Life. Fieldwork conducted between 2017-2018 concluded in three main findings: first, the study found that relations of in/formal hierarchy existed in all three researched sites. These were not always top down but also spread across different groups of people and migrants employed different tactics to surpass them, when possible; second, that ICTs are valuable among migrants for their everyday, as they offer a range of practical and sentimental uses crucial for their survival, integration and planning of the future and more importantly for combating the persisting state of liminality; thirdly, the study found that relations of solidarity were created between migrants and self-organised groups that extended well beyond the latter’s function as communication proxies. Solidarity groups played a role either in the course of affecting the migrant’s everyday life or supporting them in their struggles for freedom and survival through communication and other practices.

description: FMX101 4% contains 4% micronized minocycline (as an HCl) formulated in a lipophilic foam vehicle for topical administration. FMX101 4% has been shown to be an effective and well-tolerated treatment for moderate-to-severe acne in three Phase 3 pivotal studies, however, skin sensitization and toxicity potential remains to be fully evaluated. Four single-center, randomized, controlled, within-subject comparison studies were conducted to evaluate the potential for phototoxicity, photoallergy, skin sensitization, and cumulative skin irritation with topical administration of FMX101 4% and the corresponding vehicle. Across the four studies, healthy male and non-pregnant female volunteers (age ≥18 years) were randomized to FMX101 4%, vehicle, or other controls. In the phototoxicity study, treated skin was irradiated at 3 and 24 hr post-application, and local tolerability was assessed pre- and post-irradiation. In the photoallergy study, the skin was treated and irradiated (post-24 hr) twice weekly for 3 wk (induction phase), rested for 10–17 d, and naive skin sites were treated and irradiated (challenge phase); skin reactions were assessed after patch removal and post-irradiation. In the sensitization study, the skin was treated for 3 wk (induction phase), then rested for 10–14 d, and naive skin sites were treated for 48 hr (challenge phase); contact sensitization was assessed for both phases. In the cumulative irritation study, treatment and vehicle were applied daily for 21 d; skin irritation was assessed after each application. In all studies, standard safety assessments were conducted. A total of 32, 56, 233, and 42 subjects were enrolled in the phototoxicity, photoallergy, sensitization, and skin irritation studies, respectively. There was no evidence of phototoxicity, photoallergy, skin sensitization, or skin irritation potential with FMX101 4%. Few adverse events, mostly mild to moderate, were reported. In conclusion, FMX101 4% appeared to be well tolerated and non-irritating, and was considered to be non-sensitizing, non-phototoxic, and non-photoallergic.

description: We investigate supercurrent interference patterns measured as a function of magnetic field in ballistic graphene Josephson junctions. At high doping, the expected $Φ_{0}$-periodic "Fraunhofer" pattern is observed, indicating a uniform current distribution. Close to the Dirac point, we find anomalous interference patterns with an apparent 2$Φ_{0}$ periodicity, similar to that predicted for topological Andreev bound states carrying a charge of $e$ instead of $2e$. This feature persists with increasing temperature, ruling out a non-sinusoidal current-phase relationship. It also persists in junctions in which sharp vacuum edges are eliminated. Our results indicate that the observed behavior may originate from an intrinsic property of ballistic graphene Josephson junctions, though the exact mechanism remains unclear.

description: In a previous paper, we have proposed assigning as the value of a physical quantity in quantum theory, a certain kind of set (a sieve) of quantities that are functions of the given quantity. The motivation was in part physical---such a valuation illuminates the Kochen-Specker theorem; and in part mathematical---the valuation arises naturally in the topos theory of presheaves. This paper discusses the conceptual aspects of this proposal. We also undertake two other tasks. First, we explain how the proposed valuations could arise much more generally than just in quantum physics; in particular, they arise as naturally in classical physics. Second, we give another motivation for such valuations (that applies equally to classical and quantum physics). This arises from applying to propositions about the values of physical quantities some general axioms governing partial truth for any kind of proposition.

description: The Euler-Bernoulli model of flexible beam robots is a four-dimensional under-determined partial differential equation, related to define the unique link’s deflection of this type of robots. In this paper, Lie point symmetries of the equation have been investigated by a Lie group method. Then, reductions of the Euler-Bernoulli equation to ordinary equations have been obtained by repeat the method . Two of the reduced equations are of the first order.

 Diagnosis
 Male and female: Comparatively small- to medium-sized flies, about 5–8 mm in length (Figure 15 (a)). Frons and face covered with black hairs. Occiput whitedusted especially at posterior edges of eyes. Scutum and scutellum covered with black hairs, mixed with some white ones on the anterior margin of scutum, in addition to brownish scaly hairs that become whitish and broader at posterior margins. Wings (Figure 15 (a)) with conspicuous black-brown infuscation spread over more than the proximal half, leaving the distal portion, including the apical third of cell r1, entirely hyaline. The proximal pattern of infuscation consists of numerous irregular black-brown confluent spots. The dark spot on origin of vein R4 confluent with the upper dark colouration of wing; this spot may extend to cell r5 which is usually black-brown in basal half. A large black-brown spot found on the cross-vein m-m, sometimes slightly confluent with the infuscated half of cell r5. Cell cup and anal lobe infuscated, mainly with only small hyaline spots at middle and tip of each. Plumula white to brownish. Abdominal tergites 1–4 and anterior portion of 5th tergite covered with black scaly hairs in male, while in female, tergites 4 and 5 with broad brownish scales. Tergites 6 and 7 almost entirely covered with broad silvery white scales except for a more or less narrow mid-dorsal space in male, but these scales are less extensive on the same segments in female. Gonocoxites truncate, triangular, without apical prolongations (Figure 1 (a)); epiphallus simple with hooked apex (Figure 1 (b)). Spermatheca (Figure 1 (c)) with a long, weakly sclerotised, club-shaped bulb.

description: We consider a statistical model for finite-rank symmetric tensor factorization and prove a single-letter variational expression for its asymptotic mutual information when the tensor is of even order. The proof applies the adaptive interpolation method originally invented for rank-one factorization. Here we show how to extend the adaptive interpolation to finite-rank and even-order tensors. This requires new nontrivial ideas with respect to the current analysis in the literature. We also underline where the proof falls short when dealing with odd-order tensors.

description: Suppose that $λ- T$ is left-invertible in $L(H)$ for all $λ\in Ω$, where $Ω$ is an open subset of the complex plane. Then an operator-valued function $L(λ)$ is a left resolvent of $T$ in $Ω$ if and only if $T$ has an extension $\tilde{T}$, the resolvent of which is a dilation of $L(λ)$ of a particular form. Generalized resolvents exist on every open set $U$, with $\bar{U}$ included in the regular domain of $T$. This implies a formula for the maximal radius of regularity of $T$ in terms of the spectral radius of its generalized inverses. A solution to an open problem raised by J. Zemánek is obtained.

description: Leadership training has become increasingly popular since the latter part of the twentieth century, to the point where it is currently the highest form of non-industry specific workplace training. The number of programs on the internet offered to people in cross-sectional enterprises ranging from blue-collar manual labourers to white-collar executive exposed this popularity. It would seem from my research that employers and employees have developed an uncritical acceptance of the benefits of leadership training and that both parties hold high expectations for the outcome post-training. This research project highlights that these ideas are problematic because employees and employers have different expectations post leadership training. The initial focus of the research was to identify what led to the popularity of leadership training by focusing on why employers offer this form of training to their employees and what motivates employees to participate. Later, the emphasis moved to the expectations of both parties for the outcome following leadership training.
