description: We find new 1/8-BPS giant graviton solutions in $AdS_5 \times S^5$, carrying three angular momenta along $S^5$, and investigate their properties. Especially, we show that nonzero worldvolume gauge fields are admitted preserving supersymmetry. These gauge field modes can be viewed as electromagnetic waves along the compact D3 brane, whose Poynting vector contributes to the BPS angular momenta. We also analyze the (nearly-)spherical giant gravitons with worldvolume gauge fields in detail. Expressing the $S^3$ in Hopf fibration ($S^1$ fibred over $S^2$), the wave propagates along the $S^1$ fiber.

A method for simulating interfacial mass transfer on arbitrary meshes

description: This paper presents a method for modelling interfacial mass transfer in Interface Capturing simulations of two-phase flow with phase change. The model enables mechanistic prediction of the local rate of phase change at the vapour-liquid interface on arbitrary computational meshes and is applicable to realistic cases involving two-phase mixtures with large density ratios. The simulation methodology is based on the Volume Of Fluid (VOF) representation of the flow, whereby an interfacial region in which mass transfer occurs is implicitly identified by a phase indicator, in this case the volume fraction of liquid, which varies from the value pertaining to the "bulk" liquid to the value of the bulk vapour. The novel methodology proposed here has been implemented using the Finite Volume framework and solution methods typical of "industrial" CFD practice. The proposed methodology for capturing mass transfer is applicable to arbitrary meshes without the need to introduce elaborate but artificial smearing of the mass transfer term as is often done in other techniques. The method has been validated via comparison with analytical solutions for planar interface evaporation and bubble growth test cases, and against experimental observations of steam bubble growth.

description: This paper presents the story behind developing the Cambodia-UK prosthetics and orthotics (P&O) project âLMIC Limbsâ. We describe the methods employed in identifying and iterating the project scope, the principles underpinning our collaboration, and our reflections on the process. In the context of growing digital technology possibilities for P&O services (CAD/CAM, 3D scanning, and 3D printing or additive manufacturing), this set of principles addresses issues of:
â¢ ensuring the project is defined by a technology pull, instead of a technology push,
â¢ objectively mapping project stakeholders and the value proposition, and
â¢ consulting these stakeholders on the potential benefits and disadvantages of these technologies, and the barriers and facilitators associated with their implementation.These issues are addressed simultaneously through approaching the project development by co-design of research with equal status partnerships across nationalities and multidisciplinary team professions. As such, the project deliverables are designed according to the definition of Appropriate Technology in the context of UN Sustainable Development Goal 3: Good Health & Wellbeing.

description: There are pressing problems with traditional computing, especially for accomplishing data-intensive and real-time tasks, that motivate the development of in-memory computing devices to both store information and perform computation. Magnetic tunnel junction (MTJ) memory elements can be used for computation by manipulating a domain wall (DW), a transition region between magnetic domains. But, these devices have suffered from challenges: spin transfer torque (STT) switching of a DW requires high current, and the multiple etch steps needed to create an MTJ pillar on top of a DW track has led to reduced tunnel magnetoresistance (TMR). These issues have limited experimental study of devices and circuits. Here, we study prototypes of three-terminal domain wall-magnetic tunnel junction (DW-MTJ) in-memory computing devices that can address data processing bottlenecks and resolve these challenges by using perpendicular magnetic anisotropy (PMA), spin-orbit torque (SOT) switching, and an optimized lithography process to produce average device tunnel magnetoresistance TMR = 164%, resistance-area product RA = 31 Ω-μm^2, close to the RA of the unpatterned film, and lower switching current density compared to using spin transfer torque. A two-device circuit shows bit propagation between devices. Device initialization variation in switching voltage is shown to be curtailed to 7% by controlling the DW initial position, which we show corresponds to 96% accuracy in a DW-MTJ full adder simulation. These results make strides in using MTJs and DWs for in-memory and neuromorphic computing applications.

description: The subject of the postgraduate qualification work is single cross-polarization scattering in randomly arranged layers of inhomogeneity. The given work is dedicated to deriving a scattering field formula for particles with different polarizations, and determining the radiation intensity, and finally calculating the radiation power flux scattered from different polarization layers, through this series of theoretical studies, we can study this phenomenon more deeply. In this paper, we first introduce the basic concepts and related formulas of scattering theory. We then deduce it from a single cross-polarized scattering in a randomly arranged inhomogeneous layer and derive the scattering field formulation for particles with different polarizations. Finally, we calculated the radiant power flux scattered from different polarization layers and used a numerical simulation method to determine the radiant power flux, further verifying the accuracy of our derivation results and analyzing them in detail. We found that the radiant power flux changes with obvious regularity during the conversion process between different polarization layers. This provides an important reference for our better understanding of single cross-polarization scattering in randomly arranged inhomogeneous layers. Goal of project is - Derivation of a scattering field formula for particles with different polarizations. - Determination of radiation intensity. - Calculation of radiant power flux scattered from different polarization layers. To sum up, this paper deeply analyzes the phenomenon of single cross-polarization scattering in randomly arranged inhomogeneous layers by deriving formulas and numerical simulations. Our findings have important implications for theory and practice in related fields.

Debating liberalism and political economy in the changing global order
Creators: name: Alpeza, Tomislav
Publisher: name: University of British Columbia
Year: 2009

description: In the first chapter, this thesis exemines the legal, political and economic foundations of the liberal state. Drawing upon the works of Hobbes, Locke, Hume and Rousseau the first chapter focuses upon how the idea of natural "good" was replaced by a political "right" manifested through the law. In chapter one, the thesis criticises neo-liberalism and corporate theory in their attempts to strip nature of all intrinsic values except self-preservation. In the context of neo-liberal domination, the first chapter further argues that the legal and political foundations of the liberal state have been miscast. It defends reform liberalism against criticisms and attacks the assumption common to such criticisms that the landscape of liberalism is barren ethically. From this perspective, the second chapter injects competing neo-liberal and reform-liberal ideas into debates about the role of the state and systems of governance in, what is claimed to be, the globalized world. Troubled as the years of nationhood have been, the thesis suggests that it is misleading to summarize contemporary transformations in legal, political and economic systems under the term "globalization". The changes in the global order do not imply the withering away of the nation-state, but rather suggest a re-interpretation and transformation of its role. Besides the nation-state, macro-regional and local entities are emerging as the new sources of political, legal and economic identity. In the third chapter, the thesis explores the nature, content and legal aspects of privatization as the dominant and hugely misused tool of liberal policy. The thesis discusses the analytical framework of the term "privatization" and suggests that privatization may not be regarded exclusively as an economic process but rather should be seen as a policy tool with political, legal, economic and ethical repercussions. In chapter three, the thesis further suggests an elusive line between public and private ownership and argues that the state has direct or indirect rights in practically every economic activity under its jurisdiction, whether undertaken by individuals or public authorities. Our demand for democratization and "liberalization" of liberalism should not be devoted only to the improvement of economic efficiency and the empowerment of private ownership, but rather to the affirmation of the public sphere and changes in the structures of power. The thesis approaches ideology, government and ownership from a theoretical perspective that sees law as a constitutive part of the political, social and economic field.

description: Wireless signal recognition is becoming increasingly more significant for spectrum monitoring, spectrum management, and secure communications. Consequently, it will become a key enabler with the emerging fifth-generation (5G) and beyond 5G communications, Internet of Things networks, among others. State-of-the-art studies in wireless signal recognition have only focused on a single task which in many cases is insufficient information for a system to act on. In this work, for the first time in the wireless communication domain, we exploit the potential of deep neural networks in conjunction with multi-task learning (MTL) framework to simultaneously learn modulation and signal classification tasks. The proposed MTL architecture benefits from the mutual relation between the two tasks in improving the classification accuracy as well as the learning efficiency with a lightweight neural network model. Additionally, we consider the problem of heterogeneous wireless signals such as radar and communication signals in the electromagnetic spectrum. Accordingly, we have shown how the proposed MTL model outperforms several state-of-the-art single-task learning classifiers while maintaining a lighter architecture and performing two signal characterization tasks simultaneously. Finally, we also release the only known open heterogeneous wireless signals dataset that comprises of radar and communication signals with multiple labels.

description: Black hole solutions in higher dimensional Einstein and Einstein-Maxwell gravity have been discussed by Tangherlini as well as Myers and Perry a long time ago. These solutions are the generalizations of the familiar Schwarzschild, Reissner-Nordstrom and Kerr solutions of four-dimensional general relativity. However, higher dimensional generalization of the Kerr-Newman solution in four dimensions has not been found yet. As a first step in this direction I shall report on a new solution of the Einstein-Maxwell system of equations that describes an electrically charged and slowly rotating black hole in five dimensions.

description: We present the first complete two loop calculation of the electron EDM in the complex two-Higgs doublet model. We confirm gauge-independence by demonstrating analytic cancellation of the gauge parameter $ξ$ in the background field gauge and the 't Hooft $R_ξ$ gauge. We also investigate the behavior of the electron EDM near the decoupling limit, and determine the short- and long-distance contributions by matching onto an effective field theory. Compared with earlier studies of the electron EDM in the complex two-Higgs doublet model, we note disagreements in several places and provide diagnoses where possible. We also provide expressions for EDMs of light quarks.

description: Numerical methods are necessary to solve optimal programming and controlproblems. However, the amount of numerical computations required for even a rel ativelysimple problem is forbidding if it must be done by hand. This is why the calculusof variations found very little use in engineering and applied science until quiterecently.W ith the development of digital computers, it is now possible to solve complicatedoptimal control problems, in a reasonable length of time and at a reasonablecost. The computer uses iterative methods to solve the problem, which have thecharacteristic of solving the problem step by step and not with some kind of sweepingmethod.In this thesis we present three iterative, numerical methods of solving two-pointboundary-value problems. In Chapter 1 we present some basic theory, so that thereader will have a better understanding of the following chapters, in Chapter 2 wepresent the method of steepest descent thoroughly and in Chapters 3 and 4 we presentconcisely the methods variation of extremals and quasilinearization respectively.In Chapter 5 we compare the characteristics among the methods and in Chapter 6we present the algorithm of the steepest descent method in Mathematica and alsosome numerical examples.

Seven phonon modes (eight at low temperature) are identified at frequency below 1000 cm-1. Optical conductivity spectra are obtained by fitting all the reflectivity spectra with the factorized form of the dielectric function. Both the Born effective charges and the static optical primitivity are found to increase with decreasing temperature. Moreover, phonon linewidth narrowering and phonon modes shift with decreasing temperature are also observed, which may result from enhanced charge localization. The redshift of several low frequency modes is attributed to the spin-phonon coupling. All observed optical properties can be explained within the framework of nearest neighbor ferromagnetic(FM) spin ice model.

description: Deep learning methods for chest X-ray interpretation typically rely on pretrained models developed for ImageNet. This paradigm assumes that better ImageNet architectures perform better on chest X-ray tasks and that ImageNet-pretrained weights provide a performance boost over random initialization. In this work, we compare the transfer performance and parameter efficiency of 16 popular convolutional architectures on a large chest X-ray dataset (CheXpert) to investigate these assumptions. First, we find no relationship between ImageNet performance and CheXpert performance for both models without pretraining and models with pretraining. Second, we find that, for models without pretraining, the choice of model family influences performance more than size within a family for medical imaging tasks. Third, we observe that ImageNet pretraining yields a statistically significant boost in performance across architectures, with a higher boost for smaller architectures. Fourth, we examine whether ImageNet architectures are unnecessarily large for CheXpert by truncating final blocks from pretrained models, and find that we can make models 3.25x more parameter-efficient on average without a statistically significant drop in performance. Our work contributes new experimental evidence about the relation of ImageNet to chest x-ray interpretation performance.

description: We present theoretical approach that allows for calculation of optical functions for Cu$_2$O Quantum Well (QW) with Rydberg excitons in an external magnetic field of an arbitrary field strength. Both Faraday and Voigt configurations are considered, in the energetic region of p-excitons. We use the real density matrix approach and an effective e-h potential, which enable to derive analytical expressions for the QW magneto-optical functions. For both configurations, all three field regimes: weak, intermediate, and high field, are considered and treated separately. With the help of the developed approximeted method we are able to estimate the limits between the field regimes. The obtained theoretical magneto-absorption spectra show a good agreement with available experimental data.

description: We prove an analog of Boettcher's theorem for transcendental entire functions in the Eremenko-Lyubich class B. More precisely, let f and g be entire functions with bounded sets of singular values and suppose that f and g belong to the same parameter space (i.e., are *quasiconformally equivalent* in the sense of Eremenko and Lyubich). Then f and g are conjugate when restricted to the set of points which remain in some sufficiently small neighborhood of infinity under iteration. Furthermore, this conjugacy extends to a quasiconformal self-map of the plane. We also prove that this conjugacy is essentially unique. In particular, we show that an Eremenko-Lyubich class function f has no invariant line fields on its escaping set. Finally, we show that any two hyperbolic Eremenko-Lyubich class functions f and g which belong to the same parameter space are conjugate on their sets of escaping points.

description: Studies of Aspect-Oriented Programming (AOP) usually focus on a language in which a specific aspect extension is integrated with a base language. Languages specified in this manner have a fixed, non-extensible AOP functionality. In this paper we consider the more general case of integrating a base language with a set of domain specific third-party aspect extensions for that language. We present a general mixin-based method for implementing aspect extensions in such a way that multiple, independently developed, dynamic aspect extensions can be subject to third-party composition and work collaboratively.

description: Vacuum ultraviolet (VUV) light at 118 nm has been shown to be a powerful tool to ionize molecules for various gas-phase chemical studies. A convenient table top source of 118 nm light can be produced by frequency tripling 355 nm light from a Nd:YAG laser in xenon gas. This process has a low efficiency, typically producing only nJ/pulse of VUV light. Simple models of the tripling process predict the power of 118 nm light produced should increase quadratically with increasing xenon pressure. However, experimental 118 nm production has been observed to reach a maximum and then decrease to zero with increasing xenon pressure. Here, we describe the basic theory and experimental setup for producing 118 nm light and a new proposed model for the mechanism limiting the production based on pressure broadened absorption.

description: The purpose of this study was to elaborate on existing recommender system techniques and develop an application that will provide automatic film recommendations based on actual movie rental data provided by netflix. Recommender systems can be utilized to efficiently provide personalized services in most e-business domains. The developed application evolved in an object-oriented framework that allows effortless creation, testing and evaluation of recommender systems based on collaborative filtering techniques. The framework provides easy access to native rental data as long as complex calculated data such as Pearson-based user-to-user distances. Finally, as an example of the framework components, a set of collaborative filtering algorithms where developed. These algorithms where compared in means of recommendation speed and efficiency based on error rate. An analysis of the impact of their parameterization was also produced.

description: We consider the generic nonanticommutative model of chiral-antichiral superfields on ${\cal N}={1\over 2}$ superspace. The model is formulated in terms of an arbitrary Kählerian potential, chiral and antichiral superpotentials and can include the nonanticommutative supersymmetric sigma-model as a partial case. We study a component structure of the model and derive the component Lagrangian in an explicit form with all auxiliary fields contributions. We show that the infinite series in the classical action for generic nonanticommutative model of chiral-antichiral superfields in D=4 dimensions can be resumed in a compact expression which can be written as a deformation of standard Zumino's lagrangian and chiral superpotential. Problem of eliminating the auxiliary fields in the generic model is discussed and the first perturbative correction to the effective scalar potential is obtained.
