description: We construct the action-angle variables for the spherical part of conformal mechanics describing the motion of a particle near extreme Kerr throat. We indicate the existence of the critical point $|p_φ|=mc R_{\rm Sch}$ (with $m$ being the mass of the particle, $c$ denoting the speed of light, $R_{\rm Sch}=2γM /c^2$ being the Schwarzschild radius of a black hole with mass $M$, and $γ$ denoting the gravitational constant), where these variables are expressed in terms of elementary functions. Away from this point the action-angle variables are defined by elliptic integrals. The proposed formulation allows one to easily reconstruct the whole dynamics of the particle both in initial coordinates, as well as in the so-called conformal basis, where the Hamiltonian takes the form of conventional non-relativistic conformal mechanics. The related issues, such as semiclassical quantization and supersymmetrization are also discussed.

Multimodal identity texts : pictures of engagement for adult immigrant language learners
Creators: name: Bonham, Susan
Publisher: name: University of British Columbia
Year: 2013

description: Studies with K-12 learners have identified benefits for language and content learning when students engage in multimodal pedagogical tasks that access students’ resources for learning, but few studies have examined how a multimodal pedagogical approach might benefit adult learners in non-academic contexts. This action research study was undertaken in a government-funded English language class for adult immigrants. It investigated, from student and teacher/researcher perspectives, the opportunities and challenges of a multimodal pedagogical approach for integrated content and language learning, as well as the level of students’ investment in the unit of learning. Theoretical frameworks that informed this research project included Norton and colleagues’ concepts of identity and investment, imagined communities (Anderson, 1991) and imagined identities, new literacies theory, Kress’s theory of multimodality, and the New London Group’s theoretical overview of a pedagogy of multiliteracies. Data were collected during a unit of study on the education system in Canada and consist of observations, focus group interviews, teacher and student reflection journals, and students’ projects. Data were coded using ATLAS.ti and analyzed iteratively to identify emergent themes. Both student and teacher perspectives were that the multimodal pedagogical approach enabled students’ meaning making in ways that supported longer-term learning and development of language beyond expectations for the officially designated level of the class. Participants were very invested in the topic, and the affordances of the multimodal project supported this investment by allowing them to make meaning in multiple modes, including but not limited to linguistic modes. Themes identified in the data include: exploration of identity issues, opportunities to design with their children, importance of authentic communicative experiences, accessing prior knowledge to learn, unique characteristics and needs of adult learners, and importance of the student-teacher relationship. Tentative implications are drawn for policy, practice, and further research.

Vulnerability and adaptation to climate change in Indigenous communities in Canada and Guatemala : the role of social capital
Creators: name: Magzul, Lorenzo
Publisher: name: University of British Columbia
Year: 2013

description: The burning of fossil fuels and other human activities generating GHG are causing global warming. Global warming impacts such as droughts and floods are not uniform, and societies that are most vulnerable will be affected most. Indigenous communities are more vulnerable because they face more challenging socio-economic and environmental conditions compared to the dominant societies that surround them. However, some indigenous communities have developed strategies that enable them to adapt to climate change. Some of these adaptation strategies include the sustainable management of resources, diverse sources of income and the maintenance and reliance on social support systems–social capital. Some indigenous communities utilize networks of social support that allow them to influence their social, economic, political and environmental conditions. These networks of social support can also be utilized for the flow of information and to disseminate strategies that lead to collective action required to address the various stresses that they face. This study investigated the importance of social capital in adaptation to impacts of climate change. Two indigenous communities with different forms of livelihood: the Blood Tribe, in Canada, and the town of Patzún, in Guatemala were compared and contrasted. Understanding the role of social capital in adaptations to climate change impacts can provide adaptation insights to other indigenous communities and other vulnerable sectors. The change from a subsistence livelihood tends to reduce the social capital of these communities. In Canada, indigenous communities’ dependence on commercial activities and/or government support reflects the dramatic change from an earlier subsistence livelihood. In the highlands of Guatemala, most communities still maintain their subsistence livelihood, though it is increasingly being integrated into a market economy. The results of the investigation project show that the community of Patzún has more diverse livelihood strategies and stronger social capital compared to the Blood Tribe. The community of Patzún has a larger capacity, and therefore more options to adapt to climate change. This conclusion has implications for the current discussions on change and direction required to enhance the adaptive capacity of indigenous people and the factors that hinder their adaptation.

description: Almost all Galactic black hole binaries with low mass donor stars are transient X-ray sources; we expect most of the X-ray transients observed in external galaxies to be black hole binaries also. Obtaining period estimates for extra-galactic transients is challenging, but the resulting period distribution is an important tool for modeling the evolution history of the host galaxy. We have obtained periods, or upper limits, for 12 transients in M31, using an updated relation between the optical and X-ray luminosities. We have monitored the central region of M31 with Chandra for the last ~12 years, and followed up promising transients with HST; 4σB magnitude limits for optical counterparts are ~26--29, depending on crowding. We obtain period estimates for each transient for both neutron star and black hole accretors. Periods range from <0.4 to 490+/-90 hours (<0.97 to <175 hrs if all are BH systems). These M31 transients appear to be somewhat skewed towards shorter periods than the Milky Way (MW) transients; indeed, comparing the M31 and MW transients with survival analysis techniques used to account for some data with only upper limits yield probabilities of ~0.02--0.08 that the two populations are drawn from the same distribution. We also checked for a correlation between orbital period and distance from the nucleus, finding a 12% probability of no correlation. Further observations of M31 transients will strengthen these results.

description: The outer automorphism group Out(F_2g) of a free group on 2g generators naturally contains the mapping class group of a punctured surface as a subgroup. We define a subsurface projection of the sphere complex of the connected sum of n copies of S^1 x S^2 into the arc complex of the surface and use this to show that this subgroup is a Lipschitz retract of Out(F_2g). We also use subsurface projections to give a simple proof of a result of Handel and Mosher [HM10] stating that stabilizers of conjugacy classes of free splittings and corank 1 free factors in a free group Fn are Lipschitz retracts of Out(F_n).

description: We apply the plaquette renormalization scheme of tensor network states [Phys. Rev. E, 83, 056703 (2011)] to study the spin-1/2 frustrated Heisenberg J1-J2 model on a L*L square lattice with L = 8, 16 and 32. By treating tensor elements as variational parameters, we obtain the ground states for different J2/J1 values, and investigate the staggered magnetic order parameters, the nearest-neighbor spin-spin correlations and the plaquette order parameters. In addition to the well-known Néel-order and collinear-order at low and high J2/J1, we observe a plaquette order at intermediate J2/J1. A continuous transition between the Néel order and the plaquette order near J2 = 0.40J1 is observed. The collinear order emerges at J2 = 0.62J1 through a first-order phase transition.

Exploring the cognitive correlates of artistic practice using a parameterized non-photorealistic toolkit
Creators: name: DiPaola, Stephen
Publisher: name: University of British Columbia
Year: 2013

description: Artists and scientists have different approaches to knowledge acquisition, usage and dissemination. This research work is one attempt to bridge these different fields, through a multi-stage process involving the creation of a software toolkit for non-photorealistic rendering (NPR). Our domain of inquiry is the creation and viewing of fine art painting -- we are interested in elucidating cognitive and perceptual mechanisms or ‘cognitive correlates’ which correspond and relate to artists’ techniques and conceptions regarding fine art painting in general and portraiture in particular. As our starting point, we analyse an extensive corpus of art-theory literature to identify broadly accepted understandings and techniques, which might be relevant to human perception and cognition. We further condense this artistic knowledge into a concise set of heuristics, which are suitable for parameterization and algorithmic implementation, and examine findings from psychology and neuroscience, which correlate to each heuristic. We present our system design for a painterly NPR toolkit, which is informed by these heuristics within a suitable object-oriented, cognitively inspired architecture. By interpreting artistic and cognitive science knowledge into a well-defined computational framework, we gain opportunities to formalize and test new hypotheses. We demonstrate the productive power of such an approach by examining in depth two particular techniques (lost-and-found edges and varying fine detail level) used by a particular artist (Rembrandt). We formulate four experiments based on eye tracking of human viewers, using our painterly NPR toolkit to generate example artworks with manipulated generation parameters. We obtain significant findings suggesting that artists such as Rembrandt use techniques, which leverage perceptual and cognitive function to exert control over viewer’s gaze patterns, which in turn influences the experienced artistic merit of a painting.
Three Dimensional MHD Simulation of Circumbinary Accretion Disks: Disk Structures and Angular Momentum Transport

description: We present the first three-dimensional magnetohydrodynamic (MHD) simulations of a circumbinary disk surrounding an equal mass binary. The binary maintains a fixed circular orbit of separation $a$. As in previous hydrodynamical simulations, strong torques by the binary can maintain a gap of radius $\simeq 2a$. Streams curve inward from $r \simeq 2a$ toward the binary; some of their mass passes through the inner boundary, while the remainder swings back out to the disk. However, we also find that near its inner edge the disk develops both a strong $m=1$ asymmetry and growing orbital eccentricity. Because the MHD stresses introduce more matter into the gap, the total torque per unit disk mass is $\simeq 14$ times larger than found previously. The inner boundary accretion rate per unit disk mass is $\simeq 40$ times greater than found from previous hydrodynamical calculations. The implied binary shrinkage rate is determined by a balance between the rate at which the binary gains angular momentum by accretion and loses it by gravitational torque. The large accretion rate brings these two rates nearly into balance, but in net, we find that $\dot a/a < 0$, and its magnitude is about 2.7 times larger than predicted by the earlier hydrodynamic simulations. If the binary comprises two massive black holes, the accretion rate may be great enough for one or both to be AGN, with consequences for the physical state of the gas both in the disk body and in its inner gap.

description: A complete set of existing data on hot fusion reactions leading to synthesis of superheavy nuclei of Z =114-118, obtained in a series of experiments in Dubna and later in GSI Darmstadt and LBNL Berkeley, was analyzed in terms of a new angular-momentum dependent version of the Fusion by Diffusion (FBD) model with fission barriers and ground-state masses taken from the Warsaw macroscopic-microscopic model (involving non-axial shapes) of Kowal et al. The only empirically adjustable parameter of the model, the injection-point distance (sinj), has been determined individually for all the reactions and very regular systematics of this parameter have been established. The regularity of the obtained sinj systematics indirectly points at the internal consistency of the whole set of fission barriers used in the calculations. Having fitted all the experimental excitation functions for elements Z = 114-118, the FBD model (with the new sinj systematics) was used to predict cross sections for synthesis of elements Z = 119 and 120. Regarding prospects to produce the new element Z = 119, our calculations prefer the 252Es(48Ca,xn)300-x119 reaction, for which the synthesis cross section of about 0.2 pb in 4n channel at Ec.m.= 220 MeV is expected. The most favorable reaction to synthesize the element Z = 120 turns out to be 249Cf(50Ti,xn)299-x120, but the predicted cross section for this reaction is only 6 fb (for 3n and 4n channels).

description: Consider a family of distributions $\{π_β\}$ where $X\simπ_β$ means that $\mathbb{P}(X=x)=\exp(-βH(x))/Z(β)$. Here $Z(β)$ is the proper normalizing constant, equal to $\sum_x\exp(-βH(x))$. Then $\{π_β\}$ is known as a Gibbs distribution, and $Z(β)$ is the partition function. This work presents a new method for approximating the partition function to a specified level of relative accuracy using only a number of samples, that is, $O(\ln(Z(β))\ln(\ln(Z(β))))$ when $Z(0)\geq1$. This is a sharp improvement over previous, similar approaches that used a much more complicated algorithm, requiring $O(\ln(Z(β))\ln(\ln(Z(β)))^5)$ samples.

description: We apply the Effective Field Theory of Inflation to study the case where the continuous shift symmetry of the Goldstone boson πis softly broken to a discrete subgroup. This case includes and generalizes recently proposed String Theory inspired models of Inflation based on Axion Monodromy. The models we study have the property that the 2-point function oscillates as a function of the wavenumber, leading to oscillations in the CMB power spectrum. The non-linear realization of time diffeomorphisms induces some self-interactions for the Goldstone boson that lead to a peculiar non-Gaussianity whose shape oscillates as a function of the wavenumber. We find that in the regime of validity of the effective theory, the oscillatory signal contained in the n-point correlation functions, with n>2, is smaller than the one contained in the 2-point function, implying that the signature of oscillations, if ever detected, will be easier to find first in the 2-point function, and only then in the higher order correlation functions. Still the signal contained in higher-order correlation functions, that we study here in generality, could be detected at a subleading level, providing a very compelling consistency check for an approximate discrete shift symmetry being realized during inflation.

description: Dynamic facilitation theory assumes short-ranged dynamic constraints to be the essential feature of supercooled liquids and draws much of its conclusions from the study of kinetically constrained models. While deceptively simple, these models predict the existence of trajectories that maintain a high overlap with their initial state over many structural relaxation times. We use molecular dynamics simulations combined with importance sampling in trajectory space to test this prediction through counting long-lived particle displacements. For observation times longer than the structural relaxation time exponential tails emerge in the probability distribution of this number. Reweighting trajectories towards low mobility corresponds to a phase transition into an inactive phase. While dynamics in these two phases is drastically different structural measures show only slight differences. We discuss the choice of dynamic order parameter and give a possible explanation for the microscopic origin of the effective dynamic constraints.

description: We carry out a thorough analysis on a class of cosmological spacetimes which admit three space-like Killing vectors of Bianchi class B and contain electromagnetic fields. Using dynamical system analysis, we show that a family of vacuum plane-wave solutions of the Einstein-Maxwell equations is the stable attractor for expanding universes. Phase dynamics are investigated in detail for particular symmetric models. We integrate the system exactly for some special cases to confirm the qualitative features. Some of the obtained solutions have not been presented previously to the best of our knowledge. Finally, based on those solutions, we discuss the relation between those homogeneous models and perturbations of open FLRW universes. We argue that the vacuum plane-wave modes correspond to a certain long-wavelength limit of electromagnetic perturbations.

Evolution of free-living relatives of apicomplexan parasites
Creators: name: Janouškovec, Jan
Publisher: name: University of British Columbia
Year: 2013

description: As obligate parasites of animals and humans, apicomplexan parasites contain many unique characteristics that are critical to their lifestyle, but bear little resemblance to other eukaryotes. Several free-living relatives of apicomplexans represent a great potential in understanding early apicomplexan evolution. The photosynthetic Chromera velia provides a particular promise in addressing the long-contentious origin of the apicomplexan plastid. The data presented here provides evidence that the photosynthetic plastids in Chromera velia and another novel alga, CCMP3155 (later named Vitrella brassicaformis), are closely and specifically related to the apicomplexan plastid, and that they together are related to plastids in dinoflagellates. The ancestral plastid went through an unusual reduction in gene content and acquired unique features such as Rubisco II and transcript oligouridylylation. The plastid genome in C. velia is interesting on its own. Two proteins of Photosystem I and ATP synthase have been split to two fragments, which are independently expressed. The genome also appears to exist prevailingly as a linear monomer. These, and additional unprecedented features, redefine our understanding of plastid genome architecture and point to intra-chromosomal recombination as a putative driving force. Assessing environmental distribution of the newly-discovered Chromera and Vitrella leads to a discovery of six additional apicomplexan-related linages (ARLs) comprising 1,316 sequences primarily from coral reefs environments. The most abundant lineage, ARL-V, is novel and exclusively associated with coral tissue and surface samples. ARL-V is present in at least 20 species of symbiotic corals across time and space, which suggests that its relationship with corals is of potential significance to the reef ecosystem. Successful culturing of five Colponema isolates provides the first molecular data for another apicomplexan relative. The genus represents two independent lineages, one of which is the closest sister to apicomplexans and dinoflagellates. Mitochondrial genome data from both lineages reveals a gene-rich content and suggests that a linear monomeric structure with telomeres was ancestral to all alveolates. Altogether, this data illustrates the significance of Chromera, Vitrella, Colponema and several uncultured lineages in illuminating early evolution in apicomplexans and alveolates.

We then proceed to apply our formalism to the case of quantum harmonic oscillators, such as the motional degrees of freedom of trapped ions or nanomechanical oscillators, interacting with travelling electromagnetic modes through cavity fields and subject to external white noise. Thus, we determine the degree of squeezing that can be transferred from an intra-cavity oscillator to light, and also show that the intra-cavity squeezing can be transformed into distributed optical entanglement if one can access both output fields of a two-sided cavity.

description: A space is od-compact (resp. od-Lindelöf) provided any cover by open dense sets has a finite (resp. countable) subcover. We first show with simple examples that these properties behave quite poorly under finite or countable unions. We then investigate the relations between Lindelöfness, od-Lindelöfness and linear Lindelöfness (and similar relations with `compact'). We prove in particular that if a $T_1$ space is od-compact, then the subset of its non-isolated points is compact. If a $T_1$ space is od-Lindelöf, we only get that the subset of its non-isolated points is linearly Lindelöf. Though, Lindelöfness follows if the space is moreover locally openly Lindelöf (i.e. each point has an open Lindelöf neighborhood).

description: We describe an algorithm that associates to each positive real number $r$ and each finite collection $C_r$ of planar pixels of size $r$ a planar piecewise linear set $S_r$ with the following additional property: if $C_r$ is the collection of pixels of size $r$ that touch a given compact semialgebraic set $S$, then the normal cycle of $S_r$ converges to the normal cycle of $S$ in the sense of currents. In particular, in the limit we can recover the homotopy type of $S$ and its geometric invariants such as area, perimeter and curvature measures. At its core, this algorithm is a discretization of stratified Morse theory.

Reflectionless Transport of Surface Dirac Fermions on Topological Insulators with Induced Ferromagnetic Domain Walls

description: The properties of surface Dirac Fermions on a 3D topological insulator in proximity to a magnetic insulator with spatially textured magnetization are considered. We present an exact analytical treatment of the spectrum, the bound states and the domain wall resistance for an extended generic domain wall with in-plane and out-of-plane magnetizations. In the latter case, we find oscillations in the domain wall resistance as a function of the wall width and for certain widths a complete absence of reflections for all incoming momenta. The surprising occurrence of oscillations and the reflectionless potentials can be related to a supersymmetry of the surface Dirac Hamiltonian combined with the domain wall profile.
