description: We present a numerical study of the robustness of a specific class of non-abelian holonomic quantum gates . We take into account the parametric noise due to stochastic fluctuations of the control fields which drive the time-dependent Hamiltonian along an adiabatic loop. The performance estimator used is the state fidelity between noiseless and noisy holonomic gates. We carry over our analysis with different correlation times and we find out that noisy holonomic gates seem to be close to the noiseless ones for 'short' and 'long' noise correlation times. This result can be interpreted as a consequence of to the geometric nature of the holonomic operator. Our simulation have been performed by using parameters relevant to the excitonic proposal for implementation of holonomic quantum computation [P. Solinas et al. Phys. Rev. B 67, 121307 (2003)]

title: Vietnam's foreign policy strategy vis-à-vis China over the South China Sea issues
Creators: name: Bui, Dung Thi Thu
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: When it comes to Vietnam's response to China's threat in the South China Sea, it can be said that most of the arguments revolve around whether Vietnam employs a balancing, bandwagoning, or hedging strategy toward China. Across the literature, there is a general consensus that since the 1990s, Vietnam has engaged in a hedging strategy against China’s threat in the SCS. However, the rise of China and its increasing assertiveness in the SCS, coupled with current explanations of Vietnam’s hedging strategy, caused difficulties in identifying Vietnam’s strategic behavior toward China. Using “the patterns of hedging” built off of Koga’s hedging conceptualization (2018), this paper attempts to identify what type of hedging strategy Vietnam uses and its effectiveness in response to China’s aggressive actions in the SCS. The findings indicated first that Vietnam’s policy toward China’s challenge in the SCS fell into the hedging spectrum but leaned more towards soft hedging given a combination of economic bandwagoning and diplomatic balancing; second, while China increases maritime encroachment in the SCS, rather than pure balancing and bandwagoning, soft hedging is a less risky option for Vietnam against China.

description: We present an exact solution that describes collision of electromagnetic shock waves coupled with axion plane waves. The axion has a rather special coupling to the cross polarization term of the metric. The initial data on the null surfaces is well-defined and collision results in a singularity free interaction region. Our solution is a generalization of the Bell-Szekeres solution in the presence of an axion field.

description: Simulations expect an enhanced star-formation and active galactic nuclei (AGN) activity during galaxy mergers, which can lead to formation of binary/dual AGN. AGN feedback can enhance or suppress star-formation. We have carried out a pilot study of a sample of 10 dual nuclei galaxies with AstroSat's Ultraviolet Imaging Telescope (UVIT). Here, we present the initial results for two sample galaxies (Mrk 739, ESO 509) and deep multi-wavelength data of another galaxy (Mrk 212). UVIT observations have revealed signatures of positive AGN feedback in Mrk 739 and Mrk 212, and negative feedback in ESO 509. Deeper UVIT observations have recently been approved; these will provide better constraints on star-formation as well as AGN feedback in these systems.

description: We apply G. Prasad's volume formula for the arithmetic quotients of semi-simple groups and Bruhat-Tits theory to study the covolumes of arithmetic subgroups of SO(1,n). As a result we prove that for any even dimension n there exists a unique compact arithmetic hyperbolic n-orbifold of the smallest volume. We give a formula for the Euler-Poincare characteristic of the orbifolds and present an explicit description of their fundamental groups as the stabilizers of certain lattices in quadratic spaces. We also study hyperbolic 4-manifolds defined arithmetically and obtain a number theoretical characterization of the smallest compact arithmetic 4-manifold.

description: We introduce a new statistical tool (the TP-statistic and TE-statistic) designed specifically to compare the behavior of the sample tail of distributions with power-law and exponential tails as a function of the lower threshold u. One important property of these statistics is that they converge to zero for power laws or for exponentials correspondingly, regardless of the value of the exponent or of the form parameter. This is particularly useful for testing the structure of a distribution (power law or not, exponential or not) independently of the possibility of quantifying the values of the parameters. We apply these statistics to the distribution of returns of one century of daily data for the Dow Jones Industrial Average and over one year of 5-minutes data of the Nasdaq Composite index. Our analysis confirms previous works showing the tendency for the tails to resemble more and more a power law for the highest quantiles but we can detect clear deviations that suggest that the structure of the tails of the distributions of returns is more complex than usually assumed; it is clearly more complex that just a power law.

title: Feasibility of Representing Selected Elements of The 1985 Building Regulations in Prolog or other Rule-Based Form
Creators: name: Keevil, Philip
Publisher: name: The Open University
Year: 1998

description: This dissertation examines the proposition that there is a consistent and repeatable internal structure within regulations. This is demonstrated to be the case for regulations which make up The Building Regulations 985, which is used to illustrate many of the arguments discussed. The outcome of the research is the representation of a series of example regulations to reveal the nature of their internal structure. The form that the internal structure takes is embodied in a series of linked data structures known as 'frames' using the Prolog computer language.
Evidence for the existence of an internal structure is based upon data obtained from analysis of one year's Appeals and Determinations in a report taken from a series published from time to time by the Institute of Building Control.
Theories about the nature of prescriptive rules are discussed to introduce the subject of regulations which are described in the light of relevant legal theories about rules in general. To clarify the issues involved a systems model is proposed to provide an overview of the building regulations process. The history of regulatory control of building construction in this country is described as a prelude to considering the nature of disputes and the type of information they can yield to support the thesis. Research into the application of Artificial Intelligence techniques for processing legal statements is reviewed to establish how such experiments relate to the concept of internal structure in regulations. The appraisal identifies a number of representational problems that restrict presentation of the internal structure. The dissertation is supported by worked examples of regulations that have been analysed and by output from a sample analysis session.

description: We study a variation of the trapping reaction, A+B->A, in which both the traps (A) and the particles (B) undergo diffusion, and the traps upon meeting react according to A+A->0 or A. This two-species reaction-diffusion system is known to exhibit a non-trivial decay exponent for the B particles, and recently renormalization group methods have predicted an anomalous dimension in the BB correlation function. To test these predictions we develop a computer simulation method, motivated by the technique of Mehra and Grassberger, that determines the complete probability distribution of the B particles for a given realization of the A particle dynamics, thus providing a significant increase the quality of statistics. Our numerical results indeed reveal the anomalous dimension predicted by the renormalization group, and compare well quantitatively to precisely known values in cases where the problem can be related to a 4-walker problem.

description: A network is said to have the properties of a small world if a suitably defined average distance between any two nodes is proportional to the logarithm of the number of nodes, $N$. In this paper, we present a novel derivation of the small-world property for Gilbert-Erdös-Renyi random networks. We employ a mean field approximation that permits the analytic derivation of the distribution of shortest paths that exhibits logarithmic scaling away from the phase transition, inferable via a suitably interpreted order parameter. We begin by framing the problem in generality with a formal generating functional for undirected weighted random graphs with arbitrary disorder, recovering the result that the free energy associated with an ensemble of Gilbert graphs corresponds to a system of non-interacting fermions identified with the edge states. We then present a mean field solution for this model and extend it to more general realizations of network randomness. For a two family class of stochastic block models that we refer to as dimorphic networks, which allow for links within the different families to be drawn from two independent discrete probability distributions, we find the mean field approximation maps onto a spin chain combinatorial problem and again yields useful approximate analytic expressions for mean path lengths. Dimorophic networks exhibit a richer phase structure, where distinct small world regimes separate in analogy to the spinodal decomposition of a fluid. We find that is it possible to induce small world behavior in sub-networks that by themselves would not be in the small-world regime.

In this paper, we derive a new formula to describe VD in a head-on collision geometry of an XFEL pulse and a laser pulse. A wavefront curvature of the XFEL pulse is newly considered in this formula. With this formula, we also discuss the curvature effect on VD signals based on realistic parameters at SACLA XFEL facility.

title: Modelling the Accretion Process in Intermediate Polars
Creators: name: Taylor, Peter
Publisher: name: The Open University
Year: 1998

description: Intermediate Polars form a subclass of the cataclysmic variables, wherein a white dwarf accretes material from a main sequence star. They are inferred to have a magnetic field of ≥ 106 G which has observable effects on the accretion, in particular whether it occurs mainly through a truncated disc, or directly via a stream. The result is pulsed X-ray emissions, caused by occultation of the bright area, and absorption of the X-rays. The project concerning this thesis is to develop a computer model to simulate these pulses using the assumed physics involved, hence to constrain the physical parameters for particular systems.

 This thesis starts in Chapter 1 with an introduction to intermediate polars, setting them in context, and pointing out some of the unknown quantities and problems involved with them. Chapter 2 briefly describes some of the instrumentation used to obtain the data, and gives examples of X-ray data from some of the systems. Chapter 3 gives a more detailed examination of two particular objects, AO Psc and V1223 Sgr, using observations from the Ginga and ROSAT satellites, and concludes that both have a high inclination, and are predominantly disc-fed. Chapter 4 is the core of the thesis, in which some of the work discussed in Chapter 1 is taken further, with a detailed re-evaluation of the geometry involved, and how these are incorporated into the computer simulation. The results of using this are discussed in Chapter 5, although its use up to the present has been in investigating the parameter space rather than formally fitting to known systems. Chapter 6 discusses this latter possibility, and considers enhancements which would be useful to include. Also in this final chapter, a brief comparison to another model from a different research team is made.

Year: 2021
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We demonstrate that a separation of the velocity field in large and small scales according to a streamwise Fourier decomposition identifies subspaces with stable Lyapunov exponents and allows the dynamics to exhibit properties of an inertial manifold, such as the synchronization of the small scales in simulations sharing the same large scales or equivalently the decay of all small scale flow states to the state uniquely determined from the large scale flow. This behaviour occurs for deviations with streamwise wavelength smaller than 130 wall units which was shown in earlier studies to correspond to the streamwise spectral peak of the cross-flow velocity components of the top Lyapunov vector of the turbulent flow.
The WSRT wide-field HI survey: II. Local Group features

description: We have used the WSRT to carry out an unbiased wide-field survey of HI emission features, achieving an RMS sensitivity of about 18 mJy/Beam at a velocity resolution of 17 km/s over 1800 deg^2. In this paper we present our HI detections at negative velocities which could be distinguished from the Galactic foreground. Fully 29% of the entire survey area has high velocity HI emission with N_HI exceeding our 3 sigma limit of about 1.5x10^17cm^-2 over 30 km/s. A faint population of discrete HVCs is detected in the immediate vicinity of M31 which spans a large fraction of the M31 rotation velocity. This class of features is confined to about 12 deg (160 kpc) projected radius of M31 and appears to be physically associated. We detect a diffuse northern extension of the Magellanic Stream (MS) from at least Dec=+20 to +40 deg., which then loops back toward the south. Recent numerical simulations had predicted just such an MS extension corresponding to the apo-galacticon portion of the LMC/SMC orbit at a distance of 125 kpc. A faint bridge of HI emission appears to join the systemic velocities of M31 with that of M33 and continues beyond M31 to the north-west. This may be the first detection of HI associated with the warm-hot intergalactic medium (WHIM). The distribution of peculiar velocity HI associated with M31 can be described by a projected exponential of 25 kpc scale-length and 5x10^17cm^-2 peak column density. We present the distribution function of N_HI in the extended M31 environment, which agrees well with the low red-shift QSO absorption line data over the range log(N_HI)=17.2 to 21.9. Our data extend this comparison about two orders of magnitude lower than previously possible and provide the first image of the Lyman limit absorption system associated with an L* galaxy. (abridged)

description: In this paper we briefly comment on the observational status of the possible physical association between unidentified EGRET sources and supernova remnants (SNRs) in our Galaxy. We draw upon recent results presented in the review by Torres et al. (Physics Reports, 2003), concerning molecular gas in the vicinity of all 19 SNRs found to be positionally coincident with EGRET sources at low Galactic latitudes. In addition, we present new results regarding the supernova remnant CTA~1. Our findings disfavor the possibility of a physical connection with the nearby (in projection) EGRET source. There remains possible, however, that the compact object produced in the supernova explosion be related with the observed $γ$-ray flux.

description: The evolution of a Universe modelled as a mixture of a Chaplygin gas and radiation is determined by taking into account irreversible processes. This mixture could interpolate periods of a radiation dominated, a matter dominated and a cosmological constant dominated Universe. The results of a Universe modelled by this mixture are compared with the results of a mixture whose constituents are radiation and quintessence. Among other results it is shown that: (a) for both models there exists a period of a past deceleration with a present acceleration; (b) the slope of the acceleration of the Universe modelled as a mixture of a Chaplygin gas with radiation is more pronounced than that modelled as a mixture of quintessence and radiation; (c) the energy density of the Chaplygin gas tends to a constant value at earlier times than the energy density of quintessence does; (d) the energy density of radiation for both mixtures coincide and decay more rapidly than the energy densities of the Chaplygin gas and of quintessence.

Quark mass dependence of pseudoscalar masses and decay constants on a lattice

description: Our previous calculations of the sea- and valence-quark mass dependence of the pseudoscalar meson masses and decay constants is repeated on a 16^3x32 lattice which allows for a better determination of the quantities in question. The conclusions are similar as before on the 16^4 lattice [1]. The two light dynamical quark flavours we simulate have masses in the range 1/4 m_s < m_{u,d} < 2/3 m_s. The sea quark mass dependence of f_pi and m_pi^2/m_q is well described by the next-to-leading order (NLO) Chiral Perturbation Theory (ChPT) formulas and clearly shows the presence of chiral logarithms. The valence quark mass dependence requires the presence of NNLO contributions in Partially Quenched ChPT (PQChPT) -- in addition to the NLO terms. The O(a) lattice artifacts in these quantities turn out to be small.

Developing a process-oriented writing program that promotes elementary school children's motivation as writers : a teacher's pedagogical journey
Creators: name: Miller, Kevin Michael Eamon
Publisher: name: The University of British Columbia
Year: 2014

description: The focus of this paper is to describe the ongoing evolution of an elementary school teacher's process-oriented approach to the teaching of writing and the new support structures recently put in place within the teacher's writing program in order to promote his students motivation to write. Research literature on the historical context of the process approach to writing instruction is reviewed, as is research exploring the links between motivation - and its constituent elements, interest, self-efficacy beliefs, and self-regulation - and writing. Next, the author's impetus for changing his approach to teaching writing is discussed. Lastly, the author offers reflections on the connections between these support structures and the positive effects they may (or may not) have had on his students' experiences with writing. These support structures were introduced in the following areas : the day-to-day environment of the writing program ; the overall teaching framework chosen to deliver the author's writing program ; peer response groups ; and types of writing assignments. The paper concludes with the author's reflections on the successes he has recently observed as a writing teacher, and a brief discussion of possible directions to be taken in the writing classroom in the future.

The Wilson function transform

Publisher: name: arXiv
Year: 2003
Subjects: subject: Classical Analysis and ODEs (math.CA)
subject: FOS: Mathematics

description: Two unitary integral transforms with a very-well poised $_7F_6$-function as a kernel are given. For both integral transforms the inverse is the same as the original transform after an involution on the parameters. The $_7F_6$-function involved can be considered as a non-polynomial extension of the Wilson polynomial, and is therefore called a Wilson function. The two integral transforms are called a Wilson function transform of type I and type II. Furthermore, a few explicit transformations of hypergeometric functions are calculated, and it is shown that the Wilson function transform of type I maps a basis of orthogonal polynomials onto a similar basis of polynomials.

description: Causality is violated in the early stages of state-of-the-art heavy-ion hydrodynamic simulations. Such violations are present in up to 75% of the fluid cells in the initial time and only after 2-3 fm/$c$ of evolution do we find that 50% of the fluid cells are definitely causal. Superluminal propagation reaches up to 15% the speed of light in some of the fluid cells. The inclusion of pre-equilibrium evolution significantly reduces the number of acausal cells. Our findings suggests that relativistic causality may place constraints on the available parameter space of heavy-ion collision simulations when factored into more thorough statistical analyses.

description: Mobile Crowdsourcing (MCS) photo-based is an arising field of interest and a trending topic in the domain of ubiquitous computing. It has recently drawn substantial attention of the smart cities and urban computing communities. In fact, the built-in cameras of mobile devices are becoming the most common way for visual logging techniques in our daily lives. MCS photo-based frameworks collect photos in a distributed way in which a large number of contributors upload photos whenever and wherever it is suitable. This inevitably leads to evolving picture streams which possibly contain misleading and redundant information that affects the task result. In order to overcome these issues, we develop, in this paper, a solution for selecting highly relevant data from an evolving picture stream and ensuring correct submission. The proposed photo-based MCS framework for event reporting incorporates (i) a deep learning model to eliminate false submissions and ensure photos credibility and (ii) an A-Tree shape data structure model for clustering streaming pictures to reduce information redundancy and provide maximum event coverage. Simulation results indicate that the implemented framework can effectively reduce false submissions and select a subset with high utility coverage with low redundancy ratio from the streaming data.

First-order quasilinear canonical representation of the characteristic formulation of the Einstein equations

description: We prescribe a choice of 18 variables in all that casts the equations of the fully nonlinear characteristic formulation of general relativity in first--order quasi-linear canonical form. At the analytical level, a formulation of this type allows us to make concrete statements about existence of solutions. In addition, it offers concrete advantages for numerical applications as it now becomes possible to incorporate advanced numerical techniques for first order systems, which had thus far not been applicable to the characteristic problem of the Einstein equations, as well as in providing a framework for a unified treatment of the vacuum and matter problems. This is of relevance to the accurate simulation of gravitational waves emitted in astrophysical scenarios such as stellar core collapse.

description: We discuss various aspects of the representation theory of the local nets of von Neumann algebras on the circle associated with positive energy representations of the Virasoro algebra (Virasoro nets). In particular we classify the local extensions of the $c=1$ Virasoro net for which the restriction of the vacuum representation to the Virasoro subnet is a direct sum of irreducible subrepresentations with finite statistical dimension (local extensions of compact type). Moreover we prove that if the central charge $c$ is in a certain subset of $(1,\infty)$, including $[2,\infty)$, and $h \geq (c-1)/24$, the irreducible representation with lowest weight $h$ of the corresponding Virasoro net has infinite statistical dimension. As a consequence we show that if the central charge $c$ is in the above set and satisfies $c\leq 25$ then the corresponding Virasoro net has no proper local extensions of compact type.

General Perfect Fluid Perturbations of Homogeneous and Orthogonal Locally Rotationally Symmetric Class II Cosmologies

description: First order perturbations of homogeneous and hypersurface orthogonal LRS (Locally Rotationally Symmetric) class II cosmologies with a cosmological constant are considered in the framework of the 1+1+2 covariant decomposition of spacetime. The perturbations, which are of perfect fluid type, include general scalar, vector and tensor modes and extend some previous works where vorticity perturbations were excluded. A harmonic decomposition is performed and the field equations are then reduced to a set of eight evolution equations for eight harmonic coefficients, representing perturbations in density, shear, vorticity and the Weyl tensor, in terms of which all other variables can be expressed algebraically. This system decouples into two sub-systems, one for five and one for three coefficients. As previously known, vorticity perturbations cannot be generated to any order in a barytopic perfect fluid. Hence the time development of existing first order vorticity perturbations are seen to be completely determined by the background. However, an already existing vorticity will act as source terms in the evolution equations for the other quantities. In the high frequency approximation the four independent Weyl tensor harmonics evolve as gravitational waves on the anisotropic background in the same manner as in the case without vorticity, whereas vorticity gives a first order disturbance of sonic waves.
