description: The magnetic field dependence of energy levels in gapped single- and bilayer graphene quantum dots (QDs) defined by electrostatic gates is studied analytically in terms of the Dirac equation. Due to the absence of sharp edges in these types of QDs, the valley degree of freedom is a good quantum number. We show that its degeneracy is efficiently and controllably broken by a magnetic field applied perpendicular to the graphene plane. This opens up a feasible route to create well-defined and well controlled spin- and valley-qubits in graphene QDs. We also point out the similarities and differences in the spectrum between single- and bilayer graphene quantum dots. Striking in the case of bilayer graphene is the anomalous bulk Landau level (LL) that crosses the gap which results in crossings of QD states with this bulk LL at large magnetic fields in stark contrast to the single-layer case where this LL is absent. The tunability of the gap in the bilayer case allows us to observe different regimes of level spacings directly related to the formation of a pronounced ``Mexican hat'' in the bulk bandstructure. We discuss the applicability of such QDs to control and measure the valley isospin and their potential use for hosting and controlling spin qubits.

This action is a Dirac-consistent stand-alone action with two physical degrees of freedom per point.

A Generalized Sznajd Model

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: In the last decade the Sznajd Model has been successfully employed in modeling some properties and scale features of both proportional and majority elections. We propose a new version of the Sznajd model with a generalized bounded confidence rule - a rule that limits the convincing capability of agents and that is essential to allow coexistence of opinions in the stationary state. With an appropriate choice of parameters it can be reduced to previous models. We solved this new model both in a mean-field approach (for an arbitrary number of opinions) and numerically in a Barabasi-Albert network (for three and four opinions), studying the transient and the possible stationary states. We built the phase portrait for the special cases of three and four opinions, defining the attractors and their basins of attraction. Through this analysis, we were able to understand and explain discrepancies between mean-field and simulation results obtained in previous works for the usual Sznajd Model with bounded confidence and three opinions. Both the dynamical system approach and our generalized bounded confidence rule are quite general and we think it can be useful to the understanding of other similar models.

description: The most degenerate unitary principal series representations π_{iλ,δ} (with λ \in R, δ\in Z/2Z) of G = GL(N,R) attain the minimum of the Gelfand-Kirillov dimension among all irreducible unitary representations of G. This article gives an explicit formula of the irreducible decomposition of the restriction π_{iλ,δ}|_H (branching law) with respect to all symmetric pairs (G,H). For N=2n with n \geq 2, the restriction π_{iλ,δ}|_H remains irreducible for H=Sp(n,R) if λ\neq0 and splits into two irreducible representations if λ=0. The branching law of the restriction π_{iλ,δ}|_H is purely discrete for H = GL(n,C), consists only of continuous spectrum for H = GL(p,R) \times GL(q,R) (p+q=N), and contains both discrete and continuous spectra for H=O(p,q) (p>q\geq1). Our emphasis is laid on geometric analysis, which arises from the restriction of `small representations' to various subgroups.

description: Interpreting the J/psi suppression reported in nucleus--nucleus collisions at SPS and RHIC requires the quantitative understanding of cold nuclear matter effects, such as the inelastic rescattering of J/psi states in nuclei or the nuclear modification of parton densities. With respect to our former Glauber analysis, we include in the present work the new PHENIX d--Au measurements, and analyze as well all existing data using the EPS08 nuclear parton densities recently released. The largest suppression reported in the new PHENIX analysis leads in turn to an increase of sigma from 3.5 +/- 0.3 mb to 5.4 +/- 2.5 mb using proton PDF. The stronger x-dependence of the G^{A}/G^p ratio in EPS08 as compared to e.g. EKS98 shifts the cross section towards larger values at fixed target energies (x_2 ~ 0.1) while decreasing somehow the value extracted at RHIC (x_2 ~10^{-2}).

description: We study two-component (or pseudo-spin-1/2) Bose or Fermi gases in one dimension, in which particles are convertible between the components. Through bosonization and numerical analyses of a simple lattice model, we demonstrate that, in such gases, a strong intercomponent repulsion induces spontaneous population imbalance between the components, namely, the ferromagnetism of the pseudo spins. The imbalanced phase contains gapless charge excitations characterized as a Tomonaga-Luttinger liquid and gapped spin excitations. We uncover a crucial effect of the intercomponent particle hopping on the transition to the imbalanced phase. In the absence of this hopping, the transition is of first order. At the transition point, the energy spectrum reveals certain degeneracy indicative of an emergent SU(2) symmetry. With an infinitesimal intercomponent hopping, the transition becomes of Ising type. We determine the phase diagram of the model accurately and test the reliability of the weak-coupling bosonization formalism.

description: The beam-beam interaction is one of the dominant sources of emittance growth and luminosity lifetime deterioration. A current carrying wire has been proposed to compensate long-range beam-beam effects in the LHC and strong localized long-range beam-beam effects are experimentally investigated in the RHIC collider. Tune shift, beam transfer function, and beam loss rate are measured in dedicated experiments. In this paper, we report on simulations to study the effect of beam-wire interactions based on diffusive apertures, beam loss rates, and beam transfer function using a parallelized weak-strong beam simulation code (bbsimc). The simulation results are compared with measurements performed in RHIC during 2007 and 2008.

description: In 2017, the Evergreen State College gained national attention for a series of student protests and demonstrations centered on racial issues and social justice. The discussion regarding these events has been largely critical and mostly kept to the popular press. While we understand the who, when, and where of the Evergreen affair, our understanding of the what is underdeveloped. Student protestors filmed and streamed over eighteen hours of demonstrations, meetings, and confrontations, and due to the relatively recent ubiquity of streaming-capable smartphones, as well as the generation raised in the context of such technology, this offers a unique source of information. Utilizing computer-assisted qualitative coding, this study endeavors to understand the fundamental beliefs and moral considerations that underpinned the Evergreen affair. In the final analysis, I argue that the Evergreen affair was the manifestation of a coherent social system implicated by a thick system of belief, characterized by victimhood morality and ethnocentric ideas, which ultimately resulted in a racially hierarchical social order.

description: We study closed choice principles for different spaces. Given information about what does not constitute a solution, closed choice determines a solution. We show that with closed choice one can characterize several models of hypercomputation in a uniform framework using Weihrauch reducibility. The classes of functions which are reducible to closed choice of the singleton space, of the natural numbers, of Cantor space and of Baire space correspond to the class of computable functions, of functions computable with finitely many mind changes, of weakly computable functions and of effectively Borel measurable functions, respectively. We also prove that all these classes correspond to classes of non-deterministically computable functions with the respective spaces as advice spaces. Moreover, we prove that closed choice on Euclidean space can be considered as "locally compact choice" and it is obtained as product of closed choice on the natural numbers and on Cantor space. We also prove a Quotient Theorem for compact choice which shows that single-valued functions can be "divided" by compact choice in a certain sense. Another result is the Independent Choice Theorem, which provides a uniform proof that many choice principles are closed under composition. Finally, we also study the related class of low computable functions, which contains the class of weakly computable functions as well as the class of functions computable with finitely many mind changes. As one main result we prove a uniform version of the Low Basis Theorem that states that closed choice on Cantor space (and the Euclidean space) is low computable. We close with some related observations on the Turing jump operation and its initial topology.
Role of secrecy in meeting business competition
Creators: name: Huang, Hua Chai
Publisher: name: University of British Columbia
Year: 2011

description: Information and data are essentially the basic ingredients for the formulation of informed judgments and the making of rational decisions. In recent years, the inadequacy of business information and data available to the various segments of the economy has led them to advocate that business enterprises should disclose all their relevant and material information fully and comprehensively. Seldom, however, have they, who are outside the corporate management, given adequate consideration to the role that secrecy of business information can play in enabling competition among rival business enterprises. In this thesis, it is suggested that secrecy of some information, not full disclosure, is necessary if business enterprises are to be competitive against rivals. This study has found that the business enterprises interviewed in the field study are strongly opposed to disclosing fully and comprehensively all their information. In the views of some of the executives who are in the selected enterprises, secrecy of certain information is required not only in the maintenance of the competitive positions of their enterprises, but also as a necessary part of their competitive weaponry against rivals. Secrecy is also desired in the interests of their enterprises. Apparently, therefore, the exigencies of the various segments of the economy for business information and data cannot be met by voluntary full disclosure of information by business enterprises; certainly it is not attainable without opposition from the business community.

description: In this paper we study genus 2 curves whose Jacobians admit a polarized (4,4)-isogeny to a product of elliptic curves. We consider base fields of characteristic different from 2 and 3, which we do not assume to be algebraically closed. We obtain a full classification of all principally polarized abelian surfaces that can arise from gluing two elliptic curves along their 4-torsion and we derive the relation their absolute invariants satisfy. As an intermediate step, we give a general description of Richelot isogenies between Jacobians of genus 2 curves, where previously only Richelot isogenies with kernels that are pointwise defined over the base field were considered. Our main tool is a Galois theoretic characterization of genus 2 curves admitting multiple Richelot isogenies.

description: Extensively applied to both light and heavy meson decay and standing as one of the most successful strong decay models is the $3^P_0$ model, in which $q\bar{q}$ pair production is the dominant mechanism. The pair production can be obtained from the non-relativistic limit of a microscopic interaction Hamiltonian involving Dirac quark fields. The evaluation of the decay amplitude can be performed by a diagrammatic technique for drawing quark lines. In this paper we use an alternative approach which consists in a mapping technique, the Fock-Tani formalism, in order to obtain an effective Hamiltonian starting from same microscopic interaction. An additional effect is manifest in this formalism associated to the extended nature of mesons: bound-state corrections. A corrected $3^P_0$ is obtained and applied, as an example, to $b_{1}\toωπ$ and $a_{1}\toρπ$ decays.

description: We propose a way to remove black hole singularities by using a particular nonlinear electrodynamics Lagrangian that has been recently used in various astrophysics and cosmological frameworks. In particular, we adapt the cosmological analysis discussed in a previous work to the black hole physics. Such analysis will be improved by applying the Oppenheimer-Volkoff equation to the black hole case. At the end, fixed the radius of the star, the final density depends only on the introduced quintessential density term $ρ_γ$ and on the mass.

As a corollary we prove that for $N\ge 3$ the action of $Out(F_N)$ on the subset of $\mathbb PCurr(F_N)$ consisting of all projectivized currents with full support is properly discontinuous.

description: We evaluate the quantum discord dynamics of two qubits in independent and common non-Markovian environments. We compare the dynamics of entanglement with that of quantum discord. For independent reservoirs the quantum discord vanishes only at discrete instants whereas the entanglement can disappear during a finite time interval. For a common reservoir, quantum discord and entanglement can behave very differently with sudden birth of the former but not of the latter. Furthermore, in this case the quantum discord dynamics presents sudden changes in the derivative of its time evolution which is evidenced by the presence of kinks in its behavior at discrete instants of time.

description: Solutions to the most challenging and ambitious problems in science and engineering often require power of supercomputers. In this paper we review supercomputing research, especially in Australia and in CSIRO, and present examples of supercomputing applications in different fields of science and technology. Some examples of projects in the "Grand Challenges" category in supercomputing are summarised. One of the the most advanced supercomputing tools, UniChem from Cray Research, for molecular quantum chemistry calculations of structural, electronic, optical and other properties of molecules and clusters is presented in our recent video: "UniChem: The state-of-the-art molecular chemistry supercomputational environment. CSIRO experience - the first six months". Examples of research completed using UniChem include the studies of electronic vibrations on the C60 molecule (Buckyball), modelling of enzyme mechanisms in influenza virus, and an illustration of the work of CSIRO scientists on (the world's first) synthesis and identification of C60H36 hydrofullerenes.

description: A Markovian bridge is a probability measure taken from a disintegration of the law of an initial part of the path of a Markov process given its terminal value. As such, Markovian bridges admit a natural parameterization in terms of the state space of the process. In the context of Feller processes with continuous transition densities, we construct by weak convergence considerations the only versions of Markovian bridges which are weakly continuous with respect to their parameter. We use this weakly continuous construction to provide an extension of the strong Markov property in which the flow of time is reversed. In the context of self-similar Feller process, the last result is shown to be useful in the construction of Markovian bridges out of the trajectories of the original process.

description: In this paper we present high resolution 4.7micron spectra of the isolated Herbig Be star HD100546. HD100546 has been the subject of intense scrutiny because it is a young nearby star with a transitional disk. We observe the Delta v=1 ro-vibrational CO transitions in order to clarify the distribution of warm gas in the inner disk. Modeling of the CO spectrum indicates that the gas is vibrationally excited by collisions and UV fluorescence. The observed emission extends from 13-100AU. The inner edge of the molecular gas emission is consistent with the inner edge of the optically thick dust disk indicating that the inner hole is not simply a hole in the dust opacity but is likely cleared of gas as well. The rotational temperature of the CO is ~1000K - much hotter than the ~200K CO in the otherwise similar transitional disk surrounding HD141569. The origin of this discrepancy is likely linked to the brighter PAH emission observed toward HD100546. We use the excitation of the CO to constrain the geometry of the inner disk and comment on the evolutionary state of the system.

Husband and wife interaction in house buying
Creators: name: Egan, Michael B.
Publisher: name: University of British Columbia
Year: 2011

description: This exploratory study investigated the nature of interaction between husband and wife in the search/decision process leading to the purchase of a home. Interaction was examined in terms of convergence and divergence between the partners. It was suggested that divergence is most likely to occur over decision situations in which one or other partner dominates. A conceptual framework was constructed to examine some of the determinants of dominance. Using this scheme and several intervening variables; a number of possible interaction patterns were then suggested. A questionnaire was formulated and a field survey undertaken to verify the validity of these suggestions. The results indicated that the concepts of convergence and divergence are useful in examining this aspect of house buying behavior. The survey was, however, only partially successful in validating the conceptual framework and the suggested interaction patterns.

While the masses of the compact binary are reasonably well recovered (slightly overestimated), the same does not hold true for the spins. We show the best fit matches both in the time-domain and the frequency-domain. These encompass some of the spinning characteristics of the signal, but far less than what would be required to identify the astrophysical parameters of the system. An improvement of the matching method is necessary, though may be difficult due to the noisy signal.

The targum (1978:Apr. 3 - 1978:Apr. 28)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1978

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Our approach is differential-geometric and based on the theory of metric spaces with curvature bounded above. We use these techniques also to give another proof of the same result for the spherical buildings of classical type.

Internal control of computer applications
Creators: name: Schroeder, Harold John
Publisher: name: University of British Columbia

description: The use of computers is becoming increasingly prevalent in business. They are used, not only to store vast amounts of information, but also to carry out record keeping procedures for assets, equities and expenses that may each involve large dollar amounts. There are a variety of factors which make the computer more complex than any of the preceding innovations in the field of data processing. Perhaps the most important of these factors is the non-readable form of records that could previously be read. In their new form they are readable only when a specific effort is made to put them into readable form. Such complexities, it is suggested, mean that a new system of internal control must be prepared and maintained to ensure the protection of the records and hence the assets of the organization, especially the monetary assets. How can internal control be maintained? This is a very important problem that needs to be solved by every firm contemplating the acquisition of a computer. Failure to solve this problem prior to the time when a computerized system becomes operational, could have very serious repercussions. Retailers offering customer credit, for example, have accounts receivable that constitute a large percentage of total assets. The loss of all, or part, of the subsidiary ledger could precipitate financial ruin. The question of internal control must, therefore, be faced and procedures devised to achieve and maintain control. But how? Obviously the drastic changes in a system employing a computer leave some of the old methods of control out of date and completely inadequate. Moreover, the complexity of the new system and its machinery creates new situations requiring controls heretofore never required or visualized. It is the purpose of this thesis to identify and outline some of the internal control problems that arise with the introduction and operation of a computerized system. An attempt is made to provide solutions to these new problems as they are presented in this thesis. The problems and their solutions have been identified and organized using two main sources of information: a) the specialized literature in the field. b) case histories available to the writer, as an internal auditor significantly involved in the internal control of computerized systems.

description: The results of an extremely deep, 8-day long observation of the central kpc of the nearby starburst galaxy M82 using MERLIN (Multi-Element Radio Linked Interferometer Network) at 5 GHz are presented. The 17E-06 Jy/beam, rms noise level in the naturally weighted image make it the most sensitive high resolution radio image of M82 made to date. Over 50 discrete sources are detected, the majority of which are supernova remnants, but with 13 identified as HII regions. Sizes, flux densities and radio brightnesses are given for all of the detected sources, which are all well resolved with a majority showing shell or partial shell structures. Those sources within the sample which are supernova remnants have diameters ranging from 0.3 to 6.7 pc, with a mean size of 2.9 pc. From a comparison with previous MERLIN 5 GHz observations made in July 1992, which gives a 9.75 year timeline, it has been possible to measure the expansion velocities of ten of the more compact sources, eight of which have not been measured before. These derived expansion velocities range between 2200 and 10500 km/s.

description: We study the strong maximum principle for the heat equation associated with the Dirichlet form on countable networks. We start by analyzing the boundedness properties of the incidence operators on a countable network. Subsequently, we prove that the strong maximum principle is equivalent to the underlying graph being connected after deletion of the nodes with infinite degree. Using this result, we prove that the number of connected components of the graph with respect to the heat flow equals the number of maximal invariant ideals of the adjacency matrix.

description: The DAMA/Libra experiment has recently confirmed the annual modulation signal obtained in the earlier DAMA/NaI experiment, providing strong evidence that they have actually detected dark matter. We examine the implications of this experiment for the mirror dark matter candidate. We show that mirror dark matter successfully explains the latest DAMA/Libra data, whilst also being consistent with the null results of other direct detection experiments.

description: We re-analyze the published data on the Y(4630) --> Lambda_c Lambdabar_c and the Y(4660) --> psi(2S) pi pi with a consistent Ansatz and we find that the two observations are likely to be due to the same state Y_B with M_{Y_B} = 4660.7 +- 8.7 MeV and Gamma_{Y_B} = 61 +- 23 MeV. Under this hypothesis and reanalizing also the e+e- --> J/psi pi pi gamma_ISR spectrum we extract B(Y_B --> Lambda_c Lambdabar_c) / B(Y_B --> psi(2S) pi pi) = 25 +- 7, B(Y_B --> J/psi pi pi) / B(Y_B --> psi(2S) pi pi) < 0.46 @ 90% C.L., B(Y(4350) --> J/psi pi pi) / B(Y(4350) --> psi(2S) pi pi) < 3.4 x 10^-3 @ 90% C.L. and B(Y_B --> psi(2S) sigma) / B (Y_B --> psi(2S) f_0)=2.0 +- 0.3. These conclusions strongly support the hypothesis of Y_B being the first observation of a charmed baryonium constituted by four quarks. From the analysis of the mass spectrum and the decay properties we show that Y(4350) and Y_B are respectively consistent with the ground state and first radial excitation of the L=1 state.

description: We compute the sheaf of automorphisms of a multiplicity free Hamiltonian manifold over its momentum polytope and show that its higher cohomology groups vanish. Together with a theorem of Losev, arXiv:math/0612561, this implies a conjecture of Delzant: a compact multiplicity free Hamiltonian manifold is uniquely determined by its momentum polytope and its principal isotropy group.

title: Why more than what happens matters : robust rights and harmless wronging
Creators: name: Bowen, Joseph
Publisher: name: University of St Andrews
Year: 2020

description: This thesis examines a range of cases in which it appears one’s rights against harm are violated by another’s behaviour, even though this behaviour has done one no harm. Call these cases of harmless wronging. These cases raise a serious problem for most theories of rights, though the problem is most pronounced on the Interest Theory of Rights. According to that theory, rights necessarily protect their holder’s wellbeing. At first glance, one might think that the person’s wellbeing cannot be said to be protected by the right in cases of harmless wronging because they are not harmed in such cases—so, the necessary condition set for the ascription of a right is not satisfied. I offer a novel, welfare-based explanation of why we have rights against harmless wrongs, the Safety Condition. This holds that for someone to hold a right against us that we not perform some action, we look to whether our performing that action could easily leave them sufficiently worse off to place us under a duty. In addition to extensional accuracy, one reason for this focus on modality—on what might have been—is that it removes an objectionable form of luck from rights. And, it matters that rights do not depend on luck in this objectionable way for this requires that we, as duty-bearers, are sensitive to others’ wellbeing: that we do not only not harm others, but that we could not easily have harmed them.
The local polynomial hull near a degenerate CR singularity -- Bishop discs revisited

description: Let S be a smooth real surface in C^2 and let p\in S be a point at which the tangent plane is a complex line. How does one determine whether or not S is locally polynomially convex at such a p --- i.e. at a CR singularity ? Even when the order of contact of T_p(S) with S at p equals 2, no clean characterisation exists; difficulties are posed by parabolic points. Hence, we study non-parabolic CR singularities. We show that the presence or absence of Bishop discs around certain non-parabolic CR singularities is completely determined by a Maslov-type index. This result subsumes all known facts about Bishop discs around order-two, non-parabolic CR singularities. Sufficient conditions for Bishop discs have earlier been investigated at CR singularities having high order of contact with T_p(S). These results relied upon a subharmonicity condition, which fails in many simple cases. Hence, we look beyond potential theory and refine certain ideas going back to Bishop.

title: From ḥadīṯ to adab : the development of ʿilm narratives in Classical Arabic literature ; a case study on the Kitāb al-adab of Ibn Abī Šayba (d. 235/849) and the Kitāb al-ʿilm of Ibn Qutayba (d. 276/889)
Creators: name: Samba Campos, Estrella
Publisher: name: University of St Andrews

description: This thesis is a study on ʿilm as a literary phenomenon in the early ʿAbbāsid Arabic works on ḥadīṯ and adab. It examines the correlation between ʿilm and adab on the basis of selected foundational and pioneering Arabic primary sources from the second/eight-third/ninth centuries. ʿIlm is the term that designates the religious understanding of the Qurʾān and ḥadīṯ. The research on ḥadīṯ has overshadowed the impact of ʿilm and its literary manifestations. There has been a significant shortcoming of studies on ʿilm as a sole concept with no published contributions on the narrative aspects of ʿilm literature to date. Moreover, there is an established division in the perception of ʿilm and adab, isolating both these literary phenomena from one another. Their correlation has been largely overlooked in scholarship. This study aims at understanding ʿilm beyond ḥadīṯ focusing on a set of thematic subjects and narrative elements. It explores the interdependence of ʿilm and adab and suggests a novel perspective to overcome the dichotomy in their definition and interpretation that has been prevalent in research until now. The interconnection of ʿilm as expert knowledge and adab as conduct praxis and etiquette triggered religious narratives and social-cultural constructions of meanings that cross-pollinated one another. This thesis demonstrates that while ʿilm represented the authoritative notion, adab provided a broader potential, promoting literary creativity and a new epistemological significance to ʿilm. The examination of ʿilm as a literary phenomenon, i.e. as a discourse characterised by specific narrative, thematic and structural elements, unveils the intertextual framework spanning from ḥadīṯ to adab, in which both ʿilm and adab were developed in the premodern Arabic literature and thought.
