description: We present the dynamic velocity profiles of a Newtonian fluid (glycerol) and a viscoelastic Maxwell fluid (CPyCl/NaSal in water) driven by an oscillating pressure gradient in a vertical cylindrical pipe. The frequency range explored has been chosen to include the first three resonance peaks of the dynamic permeability of the viscoelastic fluid / pipe system. Three different optical measurement techniques have been employed. Laser Doppler Anemometry has been used to measure the magnitude of the velocity at the centre of the liquid column. Particle Image Velocimetry and Optical Deflectometry are used to determine the velocity profiles at the bulk of the liquid column and at the liquid--air interface respectively. The velocity measurements in the bulk are in good agreement with the theoretical predictions of a linear theory. The results, however, show dramatic differences in the dynamic behaviour of Newtonian and viscoelastic fluids, and demonstrate the importance of resonance phenomena in viscoelastic fluid flows, biofluids in particular, in confined geometries.

Normalizing pathologies of difference : the discursive function of IMF conditionality
Creators: name: Pahuja, Sundhya
Publisher: name: University of British Columbia
Year: 2009

description: This thesis aims to complicate conventional understandings of the way in which the "conditionally" of the International Monetary Fund operates in relation to North/South relations. Part One is comprised of three sections. The first section is a brief introduction to the context of the project, namely the need to re-examine the contemporary roles of international economic institutions in what is perceived to be a globalizing economic environment. The second section provides an outline of the methodologies being used in the paper. In this regard, the author will explain the need to compile a historical genealogy of the legal development of Fund conditionality vis a vis the South, and describe the interdisciplinary approaches to discourse analysis taken in the paper. The third section briefly sets out the origins of the International Monetary Fund and provides a background to the Fund's conditionality. Part Two is a detailed account, or historical genealogy, of the way in which the IMF became involved in the business of lending to the South. This account is directed at tracing the transformation of the Fund through what the author considers to be three major developments in the evolution of Fund conditionality. The transformation which the author argues took place was a transformation of the role of the Fund from an institution concerned primarily with managing monetary institutions between industrialised nations to a surveillance organisation directed at providing information about the Third World to the First World. Part Three takes the idea of the contemporary role of the Fund as a surveillance organisation revealed in the preceding section and explores what discursive functions the Fund might be performing in the context of the relationship between North and South. In this regard the author identifies two major themes underlying IMF discourse about the Third World both of which suggest that an underlying sense of danger of the Third World is felt by the First World, and that this sense of danger replicates older fears. The author then examines the discursive practices employed to address these fears and the extent to which they too resonate with older discursive strategies. The author then considers why the reoccurrence of these older discursive technologies might be problematic. Part Four provides some closing comments about the insights gained from the preceding analysis. In doing so, it offers a tentative suggestion for how we might productively disrupt the colonial continuum of which the discursive practices described above seem to form part.

description: We explore the possibility that quantum cosmology considerations could provide a selection principle in the landscape of string vacua. We propose that the universe emerged from the string era in a thermally excited state and determine, within a mini-superspace model, the probability of tunneling to different points on the landscape. We find that the potential energy of the tunneling end point from which the universe emerges and begins its classical evolution is determined by the primordial temperature. By taking into account some generic properties of the moduli potential we then argue that the tunneling to the tail of the moduli potentials is disfavored, that the most likely emergence point is near an extremum, and that this extremum is not likely to be in the outer region of moduli space where the compact volume is very large and the string coupling very weak. As a concrete example we discuss the application of our arguments to the KKLT model of moduli stabilization.

description: In an increasingly connected global market, news sentiment towards one company may not only indicate its own market performance, but can also be associated with a broader movement on the sentiment and performance of other companies from the same or even different sectors. In this paper, we apply NLP techniques to understand news sentiment of 87 companies among the most reported on Reuters for a period of seven years. We investigate the propagation of such sentiment in company networks and evaluate the associated market movements in terms of stock price and volatility. Our results suggest that, in certain sectors, strong media sentiment towards one company may indicate a significant change in media sentiment towards related companies measured as neighbours in a financial network constructed from news co-occurrence. Furthermore, there exists a weak but statistically significant association between strong media sentiment and abnormal market return as well as volatility. Such an association is more significant at the level of individual companies, but nevertheless remains visible at the level of sectors or groups of companies.

description: This paper considers the effects of gravitational induced uncertainty on some well-known quantum optics issues. First we will show that gravitational effects at quantum level destroy the notion of harmonic oscillations. Then it will be shown that, although it is possible(at least in principle) to have complete coherency and vanishing broadening in usual quantum optics, gravitational induced uncertainty destroys complete coherency and it is impossible to have a monochromatic ray. We will show that there is an additional wave packet broadening due to quantum gravitational effects.

description: A number of possible pulsar radio emission mechanisms are based on streaming instabilities in relativistically hot electron-positron pair plasmas. At saturation the unstable waves can form, in principle, stable solitary waves which could emit the observed intense radio signals. We searched for the proper plasma parameters which would lead to the formation of solitons, investigated their properties and dynamics as well as the resulting oscillations of electrons and positrons possibly leading to radio wave emission. We utilized a one-dimensional version of the relativistic Particle-in-Cell code ACRONYM initialized with an appropriately parameterized one-dimensional Maxwell-Jüttner velocity space particle distribution to study the evolution of the resulting streaming instability in a pulsar pair plasma. We found that strong electrostatic superluminal L-mode solitons are formed for plasmas with normalized inverse temperatures $ρ\geq 1.66$ or relative beam drift speeds with Lorentz factors $γ> 40$. The parameters of the solitons fulfill the wave emission conditions. For appropriate pulsar parameters the resulting energy densities of superluminal solitons can reach up to $1.1 \times 10^5$ erg$\cdot$cm$^{-3}$, while those of subluminal solitons reach only up to $1.2 \times 10^4$ erg$\cdot$cm$^{-3}$. Estimated energy densities of up to $7 \times 10^{12}$ erg$\cdot$cm$^{-3}$ suffice to explain pulsar nanoshots.

description: We investigate the effects of space noncommutativity and the generalized uncertainty principle on the thermodynamics of a radiating Schwarzschild black hole. We show that evaporation process is in such a way that black hole reaches to a maximum temperature before its final stage of evolution and then cools down to a nonsingular remnant with zero temperature and entropy. We compare our results with more reliable results of string theory. This comparison Shows that GUP and space noncommutativity are similar concepts at least from view point of black hole thermodynamics.

description: We present a measurement of the rate of type Ia supernovae (SNe Ia) from the first of three seasons of data from the SDSS-II Supernova Survey. For this measurement, we include 17 SNe Ia at redshift $z\le0.12$. Assuming a flat cosmology with $Ω_m = 0.3=1-Ω_Λ$, we find a volumetric SN Ia rate of $[2.93^{+0.17}_{-0.04}({\rm systematic})^{+0.90}_{-0.71}({\rm statistical})] \times 10^{-5} {\rm SNe} {\rm Mpc}^{-3} h_{70}^3 {\rm year}^{-1}$, at a volume-weighted mean redshift of 0.09. This result is consistent with previous measurements of the SN Ia rate in a similar redshift range. The systematic errors are well controlled, resulting in the most precise measurement of the SN Ia rate in this redshift range. We use a maximum likelihood method to fit SN rate models to the SDSS-II Supernova Survey data in combination with other rate measurements, thereby constraining models for the redshift-evolution of the SN Ia rate. Fitting the combined data to a simple power-law evolution of the volumetric SN Ia rate, $r_V \propto (1+z)^β$, we obtain a value of $β= 1.5 \pm 0.6$, i.e. the SN Ia rate is determined to be an increasing function of redshift at the $\sim 2.5 σ$ level. Fitting the results to a model in which the volumetric SN rate, $r_V=Aρ(t)+B\dot ρ(t)$, where $ρ(t)$ is the stellar mass density and $\dot ρ(t)$ is the star formation rate, we find $A = (2.8 \pm 1.2) \times 10^{-14} \mathrm{SNe} \mathrm{M}_{\sun}^{-1} \mathrm{year}^{-1}$, $B = (9.3^{+3.4}_{-3.1})\times 10^{-4} \mathrm{SNe} \mathrm{M}_{\sun}^{-1}$.

description: Robust stimulated Raman exact passages are requisite for controlling nonlinear quantum systems, with the wide applications ranging from ultracold molecules, non-linear optics to superchemistry. Inspired by shortcuts to adiabaticity, we propose the fast-forward scaling of stimulated Raman adiabatic processes with the nonlinearity involved, describing the transfer from an atomic Bose-Einstein condensate to a molecular one by controllable external fields. The fidelity and robustness of atom-molecule conversion are shown to surpass those of conventional adiabatic passages, assisted by fast-forward driving field. Finally, our results are extended to the fractional stimulated Raman adiabatic processes for the coherent superposition of atomic and molecular states.

Two-particle azimuthal correlations in photonuclear ultraperipheral Pb+Pb collisions at 5.02 TeV with ATLAS

description: Two-particle long-range azimuthal correlations are measured in photonuclear collisions using 1.7 nb$^{-1}$ of 5.02 TeV Pb+Pb collision data collected by the ATLAS experiment at the LHC. Candidate events are selected using a dedicated high-multiplicity photonuclear event trigger, a combination of information from the zero-degree calorimeters and forward calorimeters, and from pseudorapidity gaps constructed using calorimeter energy clusters and charged-particle tracks. Distributions of event properties are compared between data and Monte Carlo simulations of photonuclear processes. Two-particle correlation functions are formed using charged-particle tracks in the selected events, and a template-fitting method is employed to subtract the non-flow contribution to the correlation. Significant nonzero values of the second- and third-order flow coefficients are observed and presented as a function of charged-particle multiplicity and transverse momentum. The results are compared with flow coefficients obtained in proton-proton and proton-lead collisions in similar multiplicity ranges, and with theoretical expectations. The unique initial conditions present in this measurement provide a new way to probe the origin of the collective signatures previously observed only in hadronic collisions.

description: We introduce families of one-dimensional Lindblad equations describing open many-particle quantum systems that are exactly solvable in the following sense: $(i)$ the space of operators splits into exponentially many (in system size) subspaces that are left invariant under the dissipative evolution; $(ii)$ the time evolution of the density matrix on each invariant subspace is described by an integrable Hamiltonian. The prototypical example is the quantum version of the asymmetric simple exclusion process (ASEP) which we analyze in some detail. We show that in each invariant subspace the dynamics is described in terms of an integrable spin-1/2 XXZ Heisenberg chain with either open or twisted boundary conditions. We further demonstrate that Lindbladians featuring integrable operator-space fragmentation can be found in spin chains with arbitrary local physical dimension.

Canada’s international posture on human rights : consequences in the domestic domain
Creators: name: Hunter, Rebecca Winesanker
Publisher: name: University of British Columbia
Year: 2009

description: A fundamental tension exists today between the increasing willingness of states to participate in international efforts to protect fundamental human rights, and their desire to retain control over internal laws and procedures. Canada, as an active participant in international human rights regimes, has assumed numerous international obligations which have not for the most part been directly incorporated into Canadian law. Canadian law has traditionally drawn a distinction between the international obligations which Canada has undertaken as a party to international treaties, and the individual domestic rights which may be enforced in Canadian courts. In recent years, however, this distinction has become blurred. At present, the international human rights instruments to which Canada is a party have an uneasy place in Canadian law. Many courts in Canada are unfamiliar with the provisions of these instruments. In recent years the Supreme Court of Canada has increasingly demonstrated a willingness to refer to international conventions, particularly as aids in interpreting the Charter of Rights and Freedoms, but the articulation of the impact of international human rights law on domestic law remains less than clear. Canada has accepted the competence of international treaty bodies to adjudicate upon individual complaints alleging violations of international human rights obligations by Canada, yet Canada's responses to the views and requests of these treaty bodies has been inconsistent. The result is a lack of clarity regarding Canada's policies on implementation of its international human rights obligations. Questions are increasingly being raised in relation to the domestic impact of Canada's international posture on human rights. It is time that the Government of Canada recognize that there are serious issues that need to be addressed and reflect upon what steps might be taken to achieve a more rational, effective approach to the assumption and implementation of international human rights obligations. Four areas which the Government should examine in this regard are the pressing need for informed public debate, changes to the ratification process, the positions advanced before domestic courts, and the need to improve the credibility of the international treaty body process.

description: We study information-disturbance trade-off in generalized entanglement swapping protocols wherein starting from Bell pairs $\left(1,2\right)$ and $\left(3,4\right)$, one performs an arbitrary joint measurement on $\left(2,3\right)$, so that $\left(1,4\right)$ now becomes correlated. We obtain trade-off inequalities between information gain in correlations of $\left(1,4\right)$ and residual information in correlations of $\left(1,2\right)$ and $\left(3,4\right)$ respectively and argue that information contained in correlations (information) is conserved if each inequality is an equality. We show that information is conserved for a maximally entangled measurement but is not conserved for any other complete orthogonal measurement and Bell measurement mixed with white noise. However, rather surprisingly, we find that information is conserved for rank-two Bell diagonal measurements, although such measurements do not conserve entanglement. We also show that a separable measurement on $\left(2,3\right)$ can conserve information, even if, as in our example, the post-measurement states of all three pairs $\left(1,2\right)$, $\left(3,4\right)$, and $\left(1,4\right)$ become separable. This implies correlations from an entangled pair can be transferred to separable pairs in nontrivial ways so that no $information$ is lost in the process.

description: A promising route for revealing the existence of dark matter structures on mass scales smaller than the faintest galaxies is through their effect on strong gravitational lenses. We examine the role of local, lens-proximate clustering in boosting the lensing probability relative to contributions from substructure and unclustered line-of-sight (LOS) halos. Using two cosmological simulations that can resolve halo masses of $M_{\rm halo} \simeq 10^{9}\ M_{\odot}$ (in a simulation box of length $L_{\rm box}{\sim}100\,{\rm Mpc}$) and $10^{7}\ M_{\odot}$ ($L_{\rm box}\sim20\,{\rm Mpc}$), we demonstrate that clustering in the vicinity of the lens host produces a clear enhancement relative to an assumption of unclustered halos that persists to $> 20\,R_{\rm vir}$. This enhancement exceeds estimates that use a two-halo term to account for clustering, particularly within $2-5\,R_{\rm vir}$. We provide an analytic expression for this excess, clustered contribution. We find that local clustering boosts the expected count of $10^9 \ M_\odot$ perturbing halos by ${\sim}35\%$ compared to substructure alone, a result that will significantly enhance expected signals for low-redshift ($z_l \simeq 0.2$) lenses, where substructure contributes substantially compared to LOS halos. We also find that the orientation of the lens with respect to the line of sight (e.g., whether the line of sight passes through the major axis of the lens) can also have a significant effect on the lensing signal, boosting counts by an additional $\sim 50\%$ compared to a random orientations. This could be important if discovered lenses are biased to be oriented along their principal axis.

description: We present the SAO 6m telescope spectroscopy of a blue compact galaxy (BCG) HS 2134+0400 discovered in frame of the dedicated Hamburg/SAO survey for Low Metallicity BCGs (HSS-LM). Its very low abundance of oxygen (12+log(O/H) = 7.44), as well as other heavy elements (S, N, Ne, Ar), assigns this dwarf galaxy to the group of BCGs with the lowest metal content. There are only eight that low metallicity among several thousand known BCGs in the nearby Universe. The abundance ratios for the heavy elements (S/O, Ne/O, N/O, and Ar/O) are well consistent with the typical values of other very metal-poor BCGs. The global environment of HS 2134+0400 is atypical of the majority of BCGs. The object falls within the Pegasus void, the large volume with the very low density of galaxies with the normal (M_B* = -19.6) or high luminosity. Since we found in voids a dozen more the very metal-poor galaxies, we discuss the hypothesis that such objects can be representative of a substantial fraction of the void dwarf galaxy population.

description: Myopia is the most common refractive error. It is generally accepted that there is an epidemic of myopia in urban areas of East Asia, as more than 80% of the children who complete secondary school are shorted-sight, with around 20% highly myopic. Importantly, this problem is not unique to East Asia, and prevalence of myopia is increasing in other parts of the world. The high prevalence of myopia imposes costs for both optical correction and visual impairment. Furthermore, the high prevalence of severe myopia increases the risk of uncorrectable visual impairment and even blindness. Myopia has emerged as major heath issue in the world, and been included as one of the priority areas of Vision 2020. The key findings of this thesis are: 1. The prevalence of myopia has increased progressively from 20-30% to over 80% over the past 100 years in East Asia, and it is plausible that a secular shift in life-style has taken place, resulting in more intensive education and less time spent outside by most children; 2. Environmental influences played an important role during the process, as in Guangzhou, most children now become myopic, and some become highly myopic, irrespective of the refractive status of their parents. There is an additional risk of myopia in children with myopic parents, and an increased risk of developing more severe myopia for those who had severe myopic parents. Exposure to the environment in younger generations did not simply shift the population mean of the refraction; 3. Increased rates of progression in a myopic direction and increased rates of axial elongation occur prior to the onset of clinical myopia. It might therefore be possible to initiate myopia prevention before the onset of myopia. Once a myopic refraction is established, the rates of axial elongation and myopic progression are reduced. The rapid slowing of axial elongation after the onset may suggest that myopic defocus is able to inhibit myopic progression to some extent. 4. The first two years of follow up of the Guangzhou Outdoor Activity Longitudinal Study showed promising results, with a consistent pattern of reduced axial elongation and myopia development in children with outdoor intervention, although greater exposure is needed to obtain clinically significant effects.

description: A theory of electron spin-flip Raman scattering (SFRS) is presented that describes the Raman spectral signals shifted by both single and twice the electron Zeeman energy under nearly resonant excitation of the heavy hole excitons in semiconductor nanoplatelets. We analyze the spin structure of photoexcited intermediate states, derive compound matrix elements of the spin-flip scattering and obtain polarization properties of the one- and two-electron SFRS common for all the intermediate states. We show that, in the resonant scattering process under consideration, the complexes "exciton plus localized resident electrons" play the role of main intermediate states rather than tightly bound trion states. It is demonstrated that, in addition to the direct photoexcitation (and similar photorecombination) channel, there is another indirect channel contributing to the SFRS process. In the indirect channel, the photohole forms the exciton state with the resident electron removed from the localization site while the photoelectron becomes localized on this site. The theoretical results are compared with recent experimental findings for ensembles of CdSe nanoplatelets.

description: Stellar feedback is needed to produce realistic giant molecular clouds (GMCs) and galaxies in simulations, but due to limited numerical resolution, feedback must be implemented using subgrid models. Observational work is an important means to test and anchor these models, but limited studies have assessed the relative dynamical role of multiple feedback modes, particularly at the earliest stages of expansion when HII regions are still deeply embedded. In this paper, we use multiwavelength (radio, infrared, and X-ray) data to measure the pressures associated with direct radiation ($P_{\rm dir}$), dust-processed radiation ($P_{\rm IR}$), photoionization heating ($P_{\rm HII}$), and shock-heating from stellar winds ($P_{\rm X}$) in a sample of 106 young, resolved HII regions with radii $\lesssim$0.5 pc to determine how stellar feedback drives their expansion. We find that the $P_{\rm IR}$ dominates in 84% of the regions and that the median $P_{\rm dir}$ and $P_{\rm HII}$ are smaller than the median $P_{\rm IR}$ by factors of $\approx 6$ and $\approx 9$, respectively. Based on the radial dependences of the pressure terms, we show that HII regions transition from $P_{\rm IR}$-dominated to $P_{\rm HII}$-dominated at radii of $\sim$3 pc. We find a median trapping factor of $f_{\rm trap} \sim$ 8 without any radial dependence for the sample, suggesting this value can be adopted in sub-grid feedback models. Moreover, we show that the total pressure is greater than the gravitational pressure in the majority of our sample, indicating that the feedback is sufficient to expel gas from the regions.

description: We study the spin dependent tunneling of electrons through a zinc-blende semiconductor with the indirect X (or D) minimum serving as the tunneling barrier. The basic difference between tunneling through the G vs. the X barrier is the linear-k spin-orbit splitting of the two spin bands at the X point, as opposed to the k3 Dresselhaus splitting at the G point. The linear coefficient of the spin splitting b at the X point is computed for several semiconductors using density-functional theory and the transport characteristics are calculated using the barrier tunneling model. We show that both the transmission coefficient as well as the spin polarization can be large, suggesting the potential application of these materials as spin filters.

description: We discuss the realization of a universal set of ultrafast single- and two-qubit operations with superconducting quantum circuits and investigate the most relevant physical and technical limitations that arise when pushing for faster and faster gates. With the help of numerical optimization techniques, we establish a fundamental bound on the minimal gate time, which is determined independently of the qubit design solely by its nonlinearity. In addition, important practical restrictions arise from the finite qubit transition frequency and the limited bandwidth of the control pulses. We show that for highly anharmonic flux qubits and commercially available control electronics, elementary single- and two-qubit operations can be implemented in about 100 picoseconds with residual gate errors below $10^{-4}$. Under the same conditions, we simulate the complete execution of a compressed version of Shor's algorithm for factoring the number 15 in about one nanosecond. These results demonstrate that compared to state-of-the-art implementations with transmon qubits, a hundredfold increase in the speed of gate operations with superconducting circuits is still feasible.

Many paths to modernity : human rights, development and the World Bank
Creators: name: MacKenzie, David Richard
Publisher: name: University of British Columbia
Year: 2009

description: This thesis argues that development requires policies which promote comprehensive human development, rather than simple economic growth. While international law and the human rights system mandate that the individual be the central focus of the development paradigm, there are other reasons in addition to legal obligation to engage in people centred development planning. It also addresses the broad support for participatory processes found in the development planning literature. The World Bank is a multilateral development agency charged with providing low interest loans to developing nations. Frequently the development interventions financed by these loans violate the human rights of neighbouring residents. Such violations are contrary to the Bank's international legal obligations as a member of the United Nations system. This thesis enumerates steps the Bank must take to align its project planning and implementation policies with international human rights law. Chapter One summarizes World Bank history, addresses its structure, and discusses its lending policy then moves on to comment on the human rights system, providing the theory and methodology to be used throughout the thesis. The following chapters address specific Bank policies regulating project planning. Chapter Two discusses the policy regarding involuntary resettlement arising from development, and summarize the Bank's indigenous policy. Chapter Three concerns the Bank's environmental assessment policy. Chapter Four investigates two areas where no Bank policy has been developed, contrary to the requirements of the human rights system: formation of national development policies, and the detriments suffered by project affected people not covered by other policies. Each chapter discusses the nature of the relevant human rights issues, outlines Bank policy (where it exists), and recommends modifications and courses of action to bring the Bank into accordance with the human rights requirements. Chapter five reviews the conclusions reached in earlier chapters and offers a brief case study demonstrating how human rights can be practically applied in development projects. The World Bank must create policies consistent with international civil, political, economic, social and cultural rights to meet the challenges, and the legal obligations, of human development.

description: Noncommutative coordinates are decomposed into a sum of geometrical ones and a universal quantum shift operator. With the help of this operator, the mapping of a commutative field theory into a noncommutative field theory (NCFT) is introduced. A general measure for the Lorentz-invariance violation in NCFT is also derived.

description: In this letter we show that the noncommutative spaces, and in particular fuzzy spheres, are natural candidates which explicitly exhibit the holography, by noting that the smallest physically accessible volume is much larger that the expected Planckian size. Moreover, we show that fuzzy spheres provide us with a new approach, ''an $N$-tropic'' approach, to the cosmological constant problem, though in a Euclidean space-time.
