The (not so) classical productions of Peter Sellars : Ajax, Persians and Children of Heracles
Creators: name: Kallos, Marios
Publisher: name: University of British Columbia
Year: 2018

description: Peter Sellars’ reperformances of the plays belonging to the ancient Geek canon have always been controversial. Ηis radical choices regarding the performance elements, affected by and directly referencing the sociopolitical context of the time when they were staged, provide important evidence for both understanding the afterlife of classical texts on the modern stage, but also the development of Sellars as a director. More specifically, in the productions of Sophocles’ Ajax (1986), Aeschylus’ Persians (1993) and Euripides’ Children of Herakles (2003), Sellars explores how the ancient Greek tragedies can be staged in such a way as to open channels of communication and how the theatrical space can become an arena of debate, in hopes of creating an active audience, similar to that of fifth century BC Athens, where societal issues could be discussed through performative means. Drawing on reception and performance theories, reviews of the performances, interviews with Sellars and an overview of the sociopolitical context of when the three tragedies were staged, both in antiquity and the contemporary world, this thesis will explore these productions through different methodological lenses, arguing that by applying multiple methodologies we can better understand the productions and their audience reception, as well as the larger theatrical and cultural context in which they were produced. By exploring Sellars’ directorial choices, I will argue that it is not simply about how ancient plays are being reused and restaged, but also what information they can provide us regarding significant trends in contemporary American theatre during the last two decades of the twentieth century.

description: We study the spin exchange between two electrons localized in separate quantum dots in graphene. The electronic states in the conduction band are coupled indirectly by tunneling to a common continuum of delocalized states in the valence band. As a model, we use a two-impurity Anderson Hamiltonian which we subsequently transform into an effective spin Hamiltonian by way of a two-stage Schrieffer-Wolff transformation. We then compare our result to that from a Coqblin-Schrieffer approach as well as to fourth order perturbation theory.

description: Previous studies have found that Vega is surrounded by an extended debris disc that is very smooth in the far infrared, but displays possible clumpiness at 850micron and dust emission peaks at 1.3mm. We reobserved Vega at 1.3mm with PdBI to constrain its circumstellar dust distribution. Our observations of a three-field mosaic have a factor of two higher sensitivity than previous observations. We detect Vega photosphere with the expected flux, but none of the previously reported emission peaks that should have been detected at the >6sigma level, with a sensitivity <1mK. This implies that the dust distribution around Vega is principally smooth and circularly symmetric. This also means that no planet is needed to account for dust trapped in mean-motion resonnance.

policy brief

description: In short Many current challenges, such as overcoming the Covid-19 pandemic, migration, or climate change, require political action that goes beyond the national level and requires broad public legitimacy. If the values that underpin the policy-making process do not match the values and attitudes that prevail in society, the rules are not followed, or people express their dissatisfaction in protest. On highly polarizing issues, when political decisions involve choosing in favour of one side or another, it is almost impossible for policymakers to base their decisions on the conflicting attitudes and values of the entire population. In a democratic society, the key to this challenge is transparency and openness in the decision-making process. The different dimensions of values and attitudes that characterize a particular society should be considered when explaining the decisions made, facts and political decisions are not value neutral. Policy makers and the media and need to be careful about confronting different identity groups, as this exacerbates conflicts and makes decision-making more difficult. In the policy-making process, one way to avoid conflict and confrontation between two groups is to find another, unifying identity or unifying value that underpins the political message. In Latvia, one of the unifying values of society is the family and family relationships as a value.
Density functional theory based study of graphene and dielectric oxide interfaces

description: We study the effects of insulating oxides in their crystalline forms on the energy band structure of monolayer and bilayer graphene using a \textit{first principles} density functional theory based electronic structure method and a local density approximation. We consider the dielectric oxides, SiO$_{2}$ ($α$-quartz) and Al$_{2}$O$_{3}$ (alumina or $α$-sapphire) each with two surface terminations. Our study suggests that atomic relaxations and resulting equilibrium separations play a critical role in perturbing the linear band structure of graphene in contrast to the less critical role played by dangling bonds that result from cleaving the crystal in a particular direction. We also see that with the addition of a second graphene layer, the Dirac cone is restored for the quartz surface terminations. Alumina needs more than two graphene layers to preserve the Dirac cone. Our results are at best semi-quantitative for the common amorphous forms of the oxides considered. However, crystalline oxides for which our results are quantitative provide an interesting option for graphene based electronics, particularly in light of recent experiments on graphene with crystalline dielectrics (hexagonal BN) that find considerable improvements in transport properties as compared to the those with amorphous dielectrics.

description: We consider a system of identical van der Pol oscillators, globally coupled through their velocities, and study how the presence of competitive interactions affects its synchronisation properties. We will address the question from two points of view. Firstly, we will investigate the role of competitive interactions on the synchronisation among identical oscillators. Then, we will show that the presence of an intermediate fraction of repulsive links results in the appearance of macroscopic oscillations at that signal's rhythm, in regions where the individual oscillator is unable to synchronise with a weak external signal.

description: We analyze the effect of environment on the gate operation of flux-biased phase qubits. We employ the master equation for a reduced density matrix of the qubit system coupled to an Ohmic environment, described by the Caldeira-Leggett model. Numerically solving this equation, we evaluate the gate error as a function of energy splitting between qubit states, junction capacitance, and temperature. The analysis is presented for single-quadrature microwave (control) pulses as well as for two-quadrature pulses, which lower the gate error significantly for idealized systems in the absence of environment. Our results indicate that two-quadrature pulses outperform single quadrature pulses even in the presence of environment.

description: Une nouvelle approche : les mythes (Zeus, Indra, les dieux mésopotamiens comme « ordre social et moral » (R Reyes) et les forces sociales (Durkheim)
Comme l'a observé il y a longtemps Confucius, un philosophe et chef spirituel chinois qui a vécu de 551 à 479 avant J.-C., « les signes et les symboles gouvernent le monde, pas les mots ou les lois ». Comme l'a observé Rollo May, la psychologie et les sciences sociales ont largement mis de côté et marginalisé le symbolisme. Muzafer Sherif et Viktor Frankl ont tous deux souligné le fait que les différentes disciplines scientifiques et les différentes écoles de pensée sont largement séparées et déconnectées.
L'école de pensée de l'interactionnisme symbolique, qui a émergé vers 1890-1910, est une théorie sociologique qui se concentre sur la façon dont les gens créent du sens par le biais d'interactions sociales, en se basant sur l'argument selon lequel le langage et les symboles construisent le monde social. Bien que principalement en dehors des sciences sociales traditionnelles, le « symbolisme social » a fait quelques progrès. Dans son article, « Social Symbolism Forms and Functions, Elzbieta Halas énumère plus de 20 chercheurs relativement récents qui contribuent à la théorie symbolique sociale. Halas déclare : « L'action communicationnelle est un processus collectif. Fondamentalement, la vie d'un groupe est organisée autour de la communication. Plus profondément, les groupes n'existent que sur la base de la symbolisation commune de leurs membres. »
Le monde moderne a donné raison à Confucius. Pour le meilleur ou pour le pire, les symboles politiques et religieux sont les plus saillants du monde d'aujourd'hui. Le régime nazi a manipulé les symboles pour créer des motivations chez ses membres et promouvoir son idéologie. Il a utilisé une propagande largement fondée sur les symboles et le symbolisme pour défendre sa version biaisée de la vérité. Les nazis ont également encouragé la suppression des symboles religieux. Les symboles religieux sont également extrêmement populaires. Le symbole de Jésus-Christ sur la croix est un symbole prototypique.

description: The origin and possible universality of the stellar initial mass function (IMF) is a major issue in astrophysics. One of the main objectives of the Herschel Gould Belt Survey is to clarify the link between the prestellar core mass function (CMF) and the IMF. We present and discuss the core mass function derived from Herschel data for the large population of prestellar cores discovered with SPIRE and PACS in the Aquila Rift cloud complex at d ~ 260 pc. We detect a total of 541 starless cores in the entire ~11 deg^2 area of the field imaged at 70-500 micron with SPIRE/PACS. Most of these cores appear to be gravitationally bound, and thus prestellar in nature. Our Herschel results confirm that the shape of the prestellar CMF resembles the stellar IMF, with much higher quality statistics than earlier submillimeter continuum ground-based surveys.

description: A novel concept of quantum turbulence in finite size superfluids, such as trapped bosonic atoms, is discussed. We have used an atomic $^{87}\mathrm{Rb}$ BEC to study the emergence of this phenomenon. In our experiment, the transition to the quantum turbulent regime is characterized by a tangled vortex lines formation, controlled by the amplitude and time duration of the excitation produced by an external oscillating field. A simple model is suggested to account for the experimental observations. The transition from the non-turbulent to the turbulent regime is a rather gradual crossover. But it takes place in a sharp enough way, allowing for the definition of an effective critical line separating the regimes. Quantum turbulence emerging in a finite-size superfluid may be a new idea helpful for revealing important features associated to turbulence, a more general and broad phenomenon.

description: We present a new method for inferring hidden Markov models from noisy time sequences without the necessity of assuming a model architecture, thus allowing for the detection of degenerate states. This is based on the statistical prediction techniques developed by Crutchfield et al., and generates so called causal state models, equivalent to hidden Markov models. This method is applicable to any continuous data which clusters around discrete values and exhibits multiple transitions between these values such as tethered particle motion data or Fluorescence Resonance Energy Transfer (FRET) spectra. The algorithms developed have been shown to perform well on simulated data, demonstrating the ability to recover the model used to generate the data under high noise, sparse data conditions and the ability to infer the existence of degenerate states. They have also been applied to new experimental FRET data of Holliday Junction dynamics, extracting the expected two state model and providing values for the transition rates in good agreement with previous results and with results obtained using existing maximum likelihood based methods.

Re-acceleration of Nonthermal Particles at Weak Cosmological Shock Waves

description: We examine diffusive shock acceleration (DSA) of the pre-exisiting as well as freshly injected populations of nonthermal, cosmic-ray (CR) particles at weak cosmological shocks. Assuming simple models for thermal leakage injection and Alfvénic drift, we derive analytic, time-dependent solutions for the two populations of CRs accelerated in the test-particle regime. We then compare them with the results from kinetic DSA simulations for shock waves that are expected to form in intracluster media and cluster outskirts in the course of large-scale structure formation. We show that the test-particle solutions provide a good approximation for the pressure and spectrum of CRs accelerated at these weak shocks. Since the injection is extremely inefficient at weak shocks, the pre-existing CR population dominates over the injected population. If the pressure due to pre-existing CR protons is about 5 % of the gas thermal pressure in the upstream flow, the downstream CR pressure can absorb typically a few to 10 % of the shock ram pressure at shocks with the Mach number $M \la 3$. Yet, the re-acceleration of CR electrons can result in a substantial synchrotron emission behind the shock. The enhancement in synchrotron radiation across the shock is estimated to be about a few to several for $M \sim 1.5$ and $10^2-10^3$ for $M \sim 3$, depending on the detail model parameters. The implication of our findings for observed bright radio relics is discussed.

description: Much of economic theory is built on observations of aggregate, rather than individual, behavior. Here, we present novel findings on human shopping patterns at the resolution of a single purchase. Our results suggest that much of our seemingly elective activity is actually driven by simple routines. While the interleaving of shopping events creates randomness at the small scale, on the whole consumer behavior is largely predictable. We also examine income-dependent differences in how people shop, and find that wealthy individuals are more likely to bundle shopping trips. These results validate previous work on mobility from cell phone data, while describing the unpredictability of behavior at higher resolution.

description: We have used the Gemini Near-infrared Integral Field Spectrograph (NIFS) to map the age distribution of the stellar population in the inner 400 pc of the Seyfert 2 galaxy Mrk 1157 (NGC 591), at a spatial resolution of 35 pc. We have performed wavelet and principal component analysis in the data in order to remove instrumental signatures. An old stellar population component (age > 5 Gyr) is dominant within the inner ~ 130 pc which we attribute to the galaxy bulge. Beyond this region, up to the borders of the observation field, young to intermediate age components (0.1--0.7 Gyr) dominate. As for Mrk 1066, previously studied by us, we find a spatial correlation between this intermediate age component and a partial ring of low stellar velocity dispersions (sigma*). Low-sigma* nuclear rings have been observed in other active galaxies and our results for Mrk 1157 and Mrk 1066 reveal that they are formed by intermediate age stars. Such age is consistent with a scenario in which the origin of the low-sigma* rings is a past event which triggered an inflow of gas and formed stars which still keep the colder kinematics of the gas from which they have formed. No evidence for the presence of an unresolved featureless continuum and hot dust component -- as found in Mrk1066 -- are found for Mrk 1157.

description: The HDO/H2O abundance ratio is thought to be a key diagnostic on the evolution of water during the star- and planet-formation process and thus on its origin on Earth. We here present millimeter-wavelength high angular resolution observations of the deeply embedded protostar NGC1333-IRAS4B from the Submillimeter Array targeting the 3(1,2)-2(2,1) transition of HDO at 225.6 GHz (Eu = 170 K). We do not (or only very tentatively) detect the HDO line toward the central protostar, contrasting the previous prominent detection of a line from another water isotopologue, H2-18-O, with similar excitation properties using the IRAM Plateau de Bure Interferometer. The non-detection of the HDO line provides a direct, model independent, upper limit to the HDO/H2O abundance ratio of 6e(-4) (3sigma) in the warm gas associated with the central protostar. This upper limit suggests that the HDO/H2O abundance ratio is not significantly enhanced in the inner 50 AU around the protostar relative to what is seen in comets and Earth's oceans and does not support previous suggestions of a generally enhanced HDO/H2O ratio in these systems.

Craniofacial morphology and the use of neonatal non-invasive ventilation therapy
Creators: name: He, Don
Publisher: name: University of British Columbia
Year: 2018

description: Objective: A prospective cohort study with the overall objective to characterize the three-dimensional facial morphology of preterm infants over the course of the first 18 months of corrected age, participating in the Neonatal Follow-up Program of B.C. Women’s Hospital in Vancouver, BC. The specific aims of this project are to: 1. Characterize the three-dimensional facial morphology of a cohort of preterm infants at 4, 8 and 18 months of corrected age. 2. Determine the effects of the duration of NIV therapy on facial morphology at 4, 8 and 18 months of corrected age. 3. Evaluate the feasibility, time, adverse events, and minimum effect size to predict an appropriate sample size to improve study design prior to performance of a full scale longitudinal research project. Methods: To achieve this goal, infants reporting for follow-up at 4, 8 and 18 months of age corrected for prematurity will be screened for defined eligibility and imaged with a 3dMD surface-imaging camera, and facial morphometric parameters will be related to anthropometric data at birth and the specific characteristics of respiratory therapy received during the neonatal period or longer. Results: The study obtained 43 facial images: 10 images for the four-month cohort; 13 images for the 8-month cohort; 20 images for the 18-month cohort. The mean gestation age is 26 weeks, birth weight is 822 grams, birth length is 32.6 cm, and birth head circumference is 23.8 cm. The mean NIV therapy duration is 45 days and the mean NICU stay is 101 days. There was statistical significant negative correlation between intercanthal width versus duration of NIV therapy in the 4-month cohort. Conclusion: There were not any statistical significant correlations between the duration of NIV therapy and the linear distances measured in the transverse, vertical and anterior-posterior plane other than the intercanthal width. The duration of NIV therapy did not have any statistical significant correlation with measured facial angles and facial ratios. This pilot study was however not powered to detect a difference. There is overall positive feasibility for acceptability, demand, implementation, practicality, adaptation, integration and expansion of the research project.

description: Surface state localization and hybridization on B, Mg, and Li terminated MgB_2(0001) surfaces are studied within density functional theory (DFT). For the B terminated surface we find a low energy B σ_1 surface state, a spz surface state, and B σ_2 and σ_3 quantum well states, which are 90% localized in the topmost B layer. Our results demonstrate that by charging the B atomic layer, either by changing the surface termination or through electro-chemical doping, the B σ surface states are shifted down in energy, filled, and delocalize through hybridization as they cross the bulk MgB_2 bulk bands. On the other hand, the spz surface state should be shifted up in energy, emptied, and gain an increasingly metallic s character by adding a Mg, Mg^{+1}, or Li terminating atomic layer. These results clearly show both the robust nature of MgB_2(0001) surface states, and how their localization and energy range may be tuned by surface termination and charging, with implications for the superconducting and plasmonic behaviour of MgB_2.

Static two-grid mixed finite-element approximations to the Navier-Stokes equations

description: A two-grid scheme based on mixed finite-element approximations to the incompressible Navier-Stokes equations is introduced and analyzed. In the first level the standard mixed finite-element approximation over a coarse mesh is computed. In the second level the approximation is postprocessed by solving a discrete Oseen-type problem on a finer mesh. The two-level method is optimal in the sense that, when a suitable value of the coarse mesh diameter is chosen, it has the rate of convergence of the standard mixed finite-element method over the fine mesh. Alternatively, it can be seen as a postprocessed method in which the rate of convergence is increased by one unit with respect to the coarse mesh. The analysis takes into account the loss of regularity at initial time of the solution of the Navier-Stokes equations in absence of nonlocal compatibility conditions. Some numerical experiments are shown.

description: On a smooth domain in complex n space of finite D'Angelo q-type at a point, an effective upper bound for the vanishing order of the Levi determinant $\text{coeff}\{\partial r \wedge \dbar r \wedge (\partial \dbar r)^{n-q}\}$ at that point is given in terms of the D'Angelo q-type, the dimension of the space n, and q itself. The argument uses Catlin's notion of a boundary system as well as techniques pioneered by John D'Angelo.

description: We report transport measurements of composite Fermions at filling factor $ν=3/2$ in AlAs quantum wells as a function of strain and temperature. In this system the composite Fermions possess a valley degree of freedom and show piezoresistance qualitatively very similar to electrons. The temperature dependence of the resistance (R) of composite Fermions shows a metallic behavior (dR/dT > 0) for small values of valley polarization but turns insulating (dR/dT < 0) as they are driven to full valley polarization. The results highlight the importance of discrete degrees of freedom in the transport properties of composite Fermions and the similarity between composite Fermions and electrons.

Deformation-induced accelerated dynamics in polymer glasses

description: Molecular dynamics simulations are used to investigate the effects of deformation on the segmental dynamics in an aging polymer glass. Individual particle trajectories are decomposed into a series of discontinuous hops, from which we obtain the full distribution of relaxation times and displacements under three deformation protocols: step stress (creep), step strain, and constant strain rate deformation. As in experiments, the dynamics can be accelerated by several orders of magnitude during deformation, and the history dependence is entirely erased during yield (mechanical rejuvenation). Aging can be explained as a result of the long tails in the relaxation time distribution of the glass, and similarly, mechanical rejuvenation is understood through the observed narrowing of this distribution during yield. Although the relaxation time distributions under deformation are highly protocol specific, in each case they may be described by a universal acceleration factor that depends only on the strain.

description: We study structure of star-forming galaxies at z~2 in GOODS-N field selected as sBzK galaxies down to K_{AB} <24.0 mag. Among 1029 sBzK galaxies, 551 galaxies (54%) show a single component in ACS/F850LP image obtained with the Hubble Space Telescope; the rest show multiple components. We fit the single-component sBzK galaxies with the single Sérsic profile using the ACS/F850LP image and find that a majority of them (64%) show Sérsic index of n=0.5-2.5, indicating that they have a disk-like structure. The resulting effective radii typically range from 1.0 to 3.0 kpc in the rest-frame UV wavelength. After correcting the effective radii to those in the rest-frame optical wavelength, we find that the single-component sBzK galaxies locate in the region where the local and z~1 disk galaxies distribute in the stellar mass-size diagram, suggesting comparable surface stellar mass density between the sBzK and z~0-1 disk galaxies. All these properties suggest that the single-component sBzK galaxies are progenitors of the present-day disk galaxies. However, by studying their intrinsic shape through comparison between the observed distribution of apparent axial ratios and the distribution for triaxial models with axes (A>B>C), we find that the mean B/A ratio is 0.61^{+0.05}_{-0.08} and disk thickness C/A is 0.28^{+0.03}_{-0.04}. This indicates that the single-component sBzK galaxies at z~2 have a bar-like or oval shape rather than a round disk shape. The shape seems to resemble to a bar/oval structure that form through bar instability; if it is the case, the intrinsic shape may give us a clue to understand dynamical evolution of baryonic matter in a dark matter halo.

description: Violations of Lorentz boost symmetry in the electron and photon sectors can be constrained by studying several different high-energy phenomenon. Although they may not lead to the strongest bounds numerically, measurements made in terrestrial laboratories produce the most reliable results. Laboratory bounds can be based on observations of synchrotron radiation, as well as the observed absences of vacuum Cerenkov radiation. Using measurements of synchrotron energy losses at LEP and the survival of TeV photons, we place new bounds on the three electron Lorentz violation coefficients c_(TJ), at the 3 x 10^(-13) to 6 x 10^(-15) levels.

description: The crystal structure and electrical resistance of the structurally-layered EuFe2As2 have been studied up to 70 GPa and down to temperature of 10 K, using a synchrotron x-ray source and the designer diamond anvils. The room-temperature compression of the tetragonal phase of EuFe2As2 (I4/mmm) results in an increase in the a-axis and a rapid decrease in c-axis with increasing pressure. This anomalous compression reaches a maximum at 8 GPa and the tetragonal lattice behaves normal above 10 GPa with a nearly constant c/a axial ratio. The rapid rise in superconducting transition temperature (Tc) to 41 K with increasing pressure is correlated to this anomalous compression and a decrease in Tc is observed above 10 GPa. We present P-V data or equation of state of EuFe2As2 in both the ambient tetragonal phase and the high pressure collapsed tetragonal phase to 70 GPa.

Propagating Waves in a Monolayer of Gas-Fluidized Rods

description: We report on an observation of propagating compression waves in a quasi-two-dimensional monolayer of apolar granular rods fluidized by an upflow of air. The collective wave speed is an order of magnitude faster than the speed of the particles. This gives rise to anomalously large number fluctuations dN ~ $N^{0.72 \pm 0.04}$, which are greater than ordinary number fluctuations of N^{1/2}. We characterize the waves by calculating the spatiotemporal power spectrum of the density. The position of observed peaks, as a function of frequency w and wavevector k, yields a linear dispersion relationship in the long-time, long-wavelength limit and a wavespeed c = w/k. Repeating this analysis for systems at different densities and air speeds, we observe a linear increase in the wavespeed with increasing packing fraction with no dependence on the airflow. Although air-fluidized rods self-propel individually or in dilute collections, the parallel and perpendicular root-mean-square speeds of the rods indicate that they no longer self-propel when propagating waves are present. Based on this mutual exclusivity, we map out the phase behavior for the existence of waves vs self-propulsion as a function of density and fluidizing airflow.
