description: We examine one- and two-dimensional (1D and 2D) models of linearly coupled lattices of the discrete-nonlinear-Schr{ö}dinger type. Analyzing ground states of the systems with equal powers in the two components, we find a symmetry-breaking phenomenon beyond a critical value of the squared $l^2$-norm. Asymmetric states, with unequal powers in their components, emerge through a subcritical pitchfork bifurcation, which, for very weakly coupled lattices, changes into a supercritical one. We identify the stability of various solution branches. Dynamical manifestations of the symmetry breaking are studied by simulating the evolution of the unstable branches. The results present the first example of spontaneous symmetry breaking in 2D lattice solitons. This feature has no counterpart in the continuum limit, because of the collapse instability in the latter case.

description: Kination dominated quintessence models of dark energy have the intriguing feature that the relic abundance of thermal cold dark matter can be significantly enhanced compared to the predictions from standard cosmology. Previous treatments of such models do not include a realistic embedding of inflationary initial conditions. We remedy this situation by constructing a viable inflationary model in which the inflaton and quintessence field are the same scalar degree of freedom. Kination domination is achieved after inflation through a strong push or "kick" of the inflaton, and sufficient reheating can be achieved depending on model parameters. This allows us to explore both model-dependent and model-independent cosmological predictions of this scenario. We find that measurements of the B-mode CMB polarization can rule out this class of scenarios almost model independently. We also discuss other experimentally accessible signatures for this class of models.

description: The pulsar light curves and energy spectra are explored in dissipative pulsar magnetospheres with the Aristotelian electrodynamics (AE), where particle acceleration is fully balanced with radiation reaction. The AE magnetospheres with non-zero pair multiplicity are computed by a pseudo-spectral method in the co-moving frame. The dissipative region near the current sheet outside the LC is accurately captured by the high-resolution simulation. The pulsar light curves and spectra are computed by the test particle trajectory method including the influence of both the consistent accelerating electric field and radiation reaction. Our results can generally reproduce the double-peak light curves and the GeV cut-off energy spectra in agreement with the Fermi observations for the pair multiplicity $κ\gtrsim1$.

description: We suggest and implement a parallelization scheme based on an efficient multiband eigenvalue solver, called the locally optimal block preconditioned conjugate gradient LOBPCG method, and using an optimized three-dimensional (3D) fast Fourier transform (FFT) in the ab initio}plane-wave code ABINIT. In addition to the standard data partitioning over processors corresponding to different k-points, we introduce data partitioning with respect to blocks of bands as well as spatial partitioning in the Fourier space of coefficients over the plane waves basis set used in ABINIT. This k-points-multiband-FFT parallelization avoids any collective communications on the whole set of processors relying instead on one-dimensional communications only. For a single k-point, super-linear scaling is achieved for up to 100 processors due to an extensive use of hardware optimized BLAS, LAPACK, and SCALAPACK routines, mainly in the LOBPCG routine. We observe good performance up to 200 processors. With 10 k-points our three-way data partitioning results in linear scaling up to 1000 processors for a practical system used for testing.

In particular, we look for the appearance of a superradiant instability for the spinning black holes but we find no evidence of such an instability. We compare this situation with that for the smooth soliton geometries, which were recently observed to suffer from an ergoregion instability, and consider the implications for the fuzzball proposal.

description: In many-body quantum systems with spatially local interactions, quantum information propagates with a finite velocity, reminiscent of the ``light cone" of relativity. In systems with long-range interactions which decay with distance $r$ as $1/r^α$, however, there are multiple light cones which control different information theoretic tasks. We show an optimal (up to logarithms) ``Frobenius light cone" obeying $t\sim r^{\min(α-1,1)}$ for $α>1$ in one-dimensional power-law interacting systems with finite local dimension: this controls, among other physical properties, the butterfly velocity characterizing many-body chaos and operator growth. We construct an explicit random Hamiltonian protocol that saturates the bound and settles the optimal Frobenius light cone in one dimension. We partially extend our constraints on the Frobenius light cone to a several operator $p$-norms, and show that Lieb-Robinson bounds can be saturated in at most an exponentially small $e^{-Ω(r)}$ fraction of the many-body Hilbert space.

British Columbia's new reality : the politics of neo-conservatism and defensive defiance
Creators: name: Shields, John Mackie
Publisher: name: University of British Columbia
Year: 2010

description: British Columbia has long been viewed by social scientists as a laboratory for social and political experimentation. The appearance in the province in the 1980s of what Premier William Bennett termed the 'new reality' and the subsequent Social Credit government's bold new policy directives has led to close scrutiny by the academic community. A debate has begun concerning the nature and meaning of the Social Credit governments' legislative agenda, as well as the character and significance of the forces which have arisen to resist this new political direction. The importance of understanding the changing political climate in British Columbia is evident because, as past practice illustrates, what transpires in B.C. may have bearing upon political developments in other parts of Canada. This dissertation advances the argument that B.C. politics after July 1983 entered a new era. Social Credit governments, as of this date, departed from the practices of the previous Keynesian consensus, targetting the welfare state and its defenders for attack. The provincial government embraced a neo-conservative solution to the crisis of capitalism. Neo-conservatism abandons pan-class resolutions to 'political' problems, adopting instead a radical and confrontational approach. It attempts to redefine the role of the state in society, seeking the transformation of 'political’ questions into private or economic Issues capable of resolution In the market place. The province's July 1983 Budget and the 1987 Bill 19, considered herein, are the two prime examples of this rightward shift. Social Credit's conversion to neo-conservative public policy / has met with vigorous extra-parliamentary opposition which arose in both 1983 and 1987 to resist its formative legislation. While the province has long had a polarized political culture, in this 'new era’ politics has breached the confines of parliamentary-based struggle and asserted itself in the streets and workplaces. This extra-parliamentary struggle has been marked by shifting strategies and tactics and, I argue, can be best understood as 'defensive defiance' to neo-conservatism.

description: The coming-of-age streaming series, Ramy (2019) and Never Have I Ever (2020), push the boundaries of mainstream popular culture. Created by Egyptian American Muslim comedian, Ramy Youssef, and Indian American comedian, Mindy Kaling, these shows center the experiences of Arab American and Indian American communities, respectively. The producers and writers of these shows challenge ideas about how youth come of age by privileging the stories of multicultural children of immigrants. They upend Orientalist constructions and trouble assimilationist immigrant trajectories. This thesis explores how characters in both shows negotiate gendered Orientalism, push back against xenophobic constructions of the East, and redefine parameters of home in order to establish unique identities and pave their own path to belonging.
Discovery of new faint radio emission on 8$\arcdeg$ to 3$\arcmin$ scales in the Coma field, and some Galactic and extragalactic implications

description: We present a deep, 8$\degr$ diameter, 0.4 GHz radio image using a first time combination of the NAIC Arecibo 305-m telescope in Puerto Rico, and the wide-angle interferometer at the Dominion Radio Astrophysical Observatory at Penticton, Canada. Our observations are centered on the Coma Cluster of galaxies in the ``Great Wall'' of galaxies near the North Galactic Pole. The complementary nature of these two instruments enables us to produce a distortion-free image that is sensitive to radiation on scales from 8$\degr$ down to that of an individual galaxy halo at the 100 Mpc distance of the Great Wall. Newly revealed patches of distributed radio ``glow'' are seen well above the detection limit. One prominent such area coincides with groupings of radio galaxies near the Coma cluster, and indicates intergalactic IGM magnetic fields in the range 0.2 to 0.4 $μ$G on scales of up to $\sim$ 4 Mpc. Other patches of diffuse emission, not previously explored at these high latitudes on arcminute scales, probably contain Galactic ``cirrus''. A striking anticorrelation is found between low-level diffuse radio glow and some regions of enhanced optical galaxy surface density, suggesting that cosmological Large Scale Structure (LSS), normally defined by the baryonic (or dark) matter density, is not {\it uniquely} traced by faint continuum radio glow. Rather, intergalactic diffuse synchrotron radiation represents IGM magnetic and Cosmic ray energy density, instead of matter density. The diffuse, arcminute-level structures over a large region of sky are potentially important pathfinders to CMB foreground radiation on high multipole scales.

description: A number of recent, low-redshift, lensing measurements hint at a universe in which the amplitude of lensing is lower than that predicted from the $Λ$CDM model fit to the data of the Planck CMB mission. Here we use the auto- and cross-correlation signal of unWISE galaxies and Planck CMB lensing maps to infer cosmological parameters at low redshift. In particular, we consider three unWISE samples (denoted as "blue", "green" and "red") at median redshifts $z \sim 0.6$, $1.1$ and 1.5, which fully cover the Dark Energy dominated era. Our cross-correlation measurements, with combined significance $S/N \sim 80$, are used to infer the amplitude of low-redshift fluctuations, $σ_8$; the fraction of matter in the Universe, $Ω_m$; and the combination $S_8 \equiv σ_8 (Ω_m / 0.3)^{0.5}$ to which these low-redshift lensing measurements are most sensitive. The combination of blue, green and red samples gives a value $S_8=0.784\pm 0.015$, that is fully consistent with other low-redshift lensing measurements and in 2.4$σ$ tension with the CMB predictions from Planck. This is noteworthy, because CMB lensing probes the same physics as previous galaxy lensing measurements, but with very different systematics, thus providing an excellent complement to previous measurements.

description: We consider the Keller-Segel system of consumption type coupled with an incompressible fluid equation. The system describes the dynamics of oxygen and bacteria densities evolving within a fluid. We establish local well-posedness of the system in Sobolev spaces for partially inviscid and fully inviscid cases. In the latter, additional assumptions on the initial data are required when either the oxygen or bacteria density touches zero. Even though the oxygen density satisfies a maximum principle due to consumption, we prove finite time blow-up of its $C^{2}$--norm with certain initial data.

description: Linear operations on coefficients in the spherical harmonics (SH) transform domain that again yield SH-domain coefficients are an important toolset in many disciplines of research and engineering. They comprise rotations, spatially selective filters, and many other modifications for various applications, or describe the response of a MIMO system to an excitation. It is of particular importance to characterize these operations both qualitatively and quantitatively, and make them accessible for people to work with. In this paper, we identify different key properties of such operations and propose a method for their visualization. With our proposed method, we succeed to show many important aspects of an operation in a single plot and give rise to a comprehensive interpretation of the behavior of a system. In our evaluation, we show the potential of the proposed method on the basis of various practical examples from spatial audio signal processing, where SH-domain filtering is used to modify acoustic scenes given by higher-order Ambisonics signals.

The value controversy and social theory : an inquiry into Marx's 'labor theory of value'
Creators: name: Smith, Murray E. G.
Publisher: name: University of British Columbia
Year: 2010

description: The aim of this study is to establish the key importance of preserving and developing Marx's 'labor theory of value' to the project of reconstructing social theory on an 'historical-materialist' basis. The seminal significance of the conceptualization of 'economic value' to wide bodies of social theory is indicated by the profound impact of the 'marginalist' theory of value/price on twentieth-century social science — not just economic theory, but such sociological paradigms as structural functionalism and social exchange theory as well. Curiously, however, the controversy surrounding Marx's theory of value has seldom been addressed by sociologists seeking to elaborate a Marxist alternative to these paradigms. The present study seeks to redress this situation by a) 'demystifying' the value controversy by disclosing its methodological, theoretical and programmatic roots, b) establishing in Marx's 'value' a category which is useful not only to the explication of capitalist reality but also in the understanding of the 'forces-relations' dialectic which is at the heart of Marx's theory of historical development, and c) demonstrating how Marx's value theory transcends the conventional academic bifurcation of the 'economic' and the 'sociological’. In contrast to the marginalist doctrine, which analyzes the relation between 'things' and 'persons', Marx's theory of value focuses on the relation of people to people within the total process of production/reproduction: the social relations of production. Accordingly, Marx's theory is not essentially a theory of individual price formation, but rather of the articulation, division and distribution of social labor within commodity-producing economies, and of the laws of motion of societies characterized by 'generalized' commodity production. Key to this interpretation of Marx's project is the historical materialist thesis that the most significant theoretical distinction of use in the interrogation of the human world is the distinction between the material (or 'natural') and the social, not the distinction between a material 'object world' and an ideal 'subject world' which is basic to theories influencing and influenced by neo-classical marginalism. To bring the methodological and substantive-theoretical implications of Marx's theory of value into full view, a comparative critical analysis of the principal 'schools' that have participated in the value controversy is undertaken. These implications are then explored in relation to such problems as economic crisis, imperialism/underdevelopment, class structuration, the social determination of knowledge/ideology, bureaucracy, and the current 'crisis' of social theory as expressed in the division between a poitivistic scientism and a 'life-philosophical' humanism.

description: An intermediate nematic phase is proposed for the interpretation of recent experimental results on phase biaxiality in bent-core nematics. The phase is macroscopically uniaxial but consists of microscopic biaxial, and possibly polar, domains. On applying an electric field the phase exhibits substantial macroscopic biaxial ordering resulting from the collective alignment of the domains. A phenomenological theory is developed for the molecular order in this phase and for its transitions to purely uniaxial and to spontaneously biaxial nematic phases.

description: We apply the Dirac procedure for constrained systems to the Arnowitt-Deser-Misner formalism linearized around the Bianchi I universe. We discuss and employ basic concepts such as Dirac observables, Dirac brackets, gauge-fixing conditions, reduced phase space, physical Hamiltonian, canonical isomorphism between different gauge-fixing surfaces and spacetime reconstruction. We relate this approach to the gauge-fixing procedure for non-perturbative canonical relativity. We discuss the issue of propagating a basis for the scalar-vector-tensor decomposition as, in an anisotropic universe, the wavefronts of plane waves undergo a nontrivial evolution. We show that the definition of a gravitational wave as a traceless-transverse mode of the metric perturbation needs to be revised. Moreover there exist coordinate systems in which a polarization mode of the gravitational wave is given entirely in terms of a scalar metric perturbation. We first develop the formalism for the universe with a single scalar field and then extend it to the multi-field case. The obtained fully canonical formalism will serve as a starting point for a complete quantization of the cosmological perturbations and the cosmological background.

description: We present results from a detailed spectrophotometric analysis of the blue compact dwarf galaxy Mrk 35 (Haro 3), based on deep optical (B,V,R,I) and near-IR (J,H,K) imaging, Halpha narrow-band observations and long-slit spectroscopy. The optical emission of the galaxy is dominated by a central young starburst, with a bar-like shape, while an underlying component of stars, with elliptical isophotes and red colors, extends more than 4 kpc from the galaxy center. High resolution Halpha and color maps allow us to identify the star-forming regions, to spatially discriminate them from the older stars, and to recognize several dust patches. We derive colors and Halpha parameters for all the identified star-forming knots. Observables derived for each knot are corrected for the contribution of the underlying older stellar population, the contribution by emission lines, and from interstellar extinction, and compared with evolutionary synthesis models. We find that the contributions of these three factors are by no means negligible and that they significantly vary across the galaxy. Therefore, careful quantification and subtraction of emission lines, galaxy host contribution, and interstellar reddening at every galaxy position, are essential to derive the properties of the young stars in BCDs. We find that we can reproduce the colors of all the knots with an instantaneous burst of star formation and the Salpeter initial mass function with an upper mass limit of 100 M_solar. In all cases the knots are just a few Myr old. The underlying population of stars has colors consistent with being several Gyr old.

description: The Silent Dragons is an 18-minute work for chamber ensemble and male chorus. The voice part has no literary or linguistic content, but uses phonemes for their sonic and expressive character. Compositional activity is organized into two essential layers; texture and drone. In its many forms, the textural layer persists throughout the entire composition and is perceived as the concurrence of two distinct continuums; the continuum of cumulative rhythmic effect in which the listener registers and interprets change in the total attack rhythm, and the continuum of textural transformation in which one perceives transitions from one overall textural condition to another. Both continuums arise from the consistent change in the structure of successive textural sonorities. Unlike texture, the drone lasts just one half the composition's overall length and is positioned temporally in the textural layer as a central segment. Both texture and drone are structured similarly in ternary form; the ternary form of the drone is contained within the ternary form of the textural layer. In this sense, and in the impression they make, texture and drone, respectively, provide the composition with primary and secondary forms of continuity. Each continuity has a strategic interim destination, an event, that activity 'must' proceed to and recede from; these destinations are, therefore, climatic in nature and are perceived as the two most significant events in the composition. Apart from sonority, texture and drone are distinguished primarily with reference to tonality; the textural layer is essentially non-tonal and is perceived, by and large, in terms of color and rhythm. The drone, however, is designed to induce a sense of tonality by means of heterophonic and linear relationships that conduce to perceptions of pitch emphasis and, ultimately, pitch centricity.
BUSCOMP: BUSCO compilation and comparison – Assessing completeness in multiple genome assemblies
Creators: name: Edwards, Richard J.
Publisher: name: F1000 Research Limited
Year: 2019

description: BUSCO is a widely used tool in genomics for estimating the "completeness" of a genome assembly. However, BUSCO can produce surprising results, due to its reliance on tblastn and gene predictions. In this presentation, I introduce BUSCOMP, a bioinformatics tool to complement BUSCO genome completeness estimates for:

	Comparing BUSCO scores across assemblies
	Compiling a set of "best" complete BUSCO genes
	Robust, consistent and intuitive benchmarking of draft assembly "completeness"

description: This volume covers Leg 60 of the cruises of the Drilling Vessel Glomar Challenger. A major goal of DSDP sampling of tectonically active ocean margins has been to obtain a complete transect of an interoceanic subduction zone- island arc-back-arc basin system. A classic example of such a system is in the western Pacific, where an apparent series of back-arc basins and volcanic arcs have formed behind (west of) the Mariana Trench. Two consecutive drilling legs (Legs 59 and 60) were assigned to drill an east-west transect of sites along latitude 18°N, from the Mariana Basin of the Pacific Ocean to the oldest inactive island arcs and back-arc spreading basins of the Philippine Sea. The western (older, inactive) half of this transect (Philippine Sea, Palau-Kyushu Ridge, Parece Vela Basin, and the West Mariana Ridge—Sites 447-451) was drilled during Leg 59. The objective of Leg 60 was to sample the tectonically active eastern portion of the transect in a closely spaced series of holes across the presently opening back-arc basin (Mariana Trough, Sites 453-456), the Mariana arc itself (Site 457), the Mariana fore-arc region (Sites 458 and 459), and deep within the Mariana Trench (Sites 460 and 461). In addition, one site (Site 452) was drilled on the Pacific plate seaward of the trench to obtain a reference section of sediments and oceanic crust being delivered to the trench. Although even this geographical concentration of drill sites provided sparse data in the complex arc-trench system, it was hoped that by drilling each of the primary structural elements of the area we could elucidate the spreading, subsidence, and sedimentation history of the Mariana Trough, the volcanic and tectonic history of the Mariana arc, and the tectonic history of the trench and fore-arc region. Leg 60 began on 15 March, 1978 at Apra, Guam and ended at the same location on 15 May, 1978. During Leg 60, the Glomar Challenger traveled 2445 nautical miles and attempted to drill 17 holes at 10 sites.

Improving reproducibility from meeting notes to manuscripts using Curvenote
Creators: name: Cockett, Rowan
Publisher: name: Zenodo
Year: 2021
Subjects: Scientific Writing

description: In this presentation we introduce a new tool, Curvenote (curvenote.com), that is built for collaborative scientific writing. Curvenote is designed to improve content reuse, discoverability, interactivity, and reproducibility as researchers evolve their notes, computational notebooks (e.g. in Jupyter), and other content into traditional scientific artifacts including papers, presentations, and textbooks. We will discuss Curvenote’s block-based version control, how this system relates to DOIs, and the implications on content reuse as scientific communication moves towards open-access, smaller & faster publications, and continuous open-science practices.
Self-duality protected multi-criticality in deconfined quantum phase transitions

description: Duality places an important constraint on the renormalization group flows and the phase diagrams. For self-dual theories, the self-duality can be promoted as a symmetry, this leads to the multi-criticalities. This work investigates a description of the deconfined quantum criticality, the $N_f=2$ QED$_3$, as an example of self-dual theories and its multi-critical behavior under perturbative deformations. The multi-criticality is described by the theory with Gross-Neveu couplings and falls in a different universality class than the standard deconfined quantum criticality. We systematically calculate the scaling dimensions of various operators in the 3d quantum electrodynamics with the Chern-Simons term and Gross-Neveu couplings by the large-$N$ renormalization group analysis. Specifically, we find certain non-relativistic four-fermion interactions corresponding to the dimer-dimer interactions in the lattice model will drive the deconfined quantum criticality to the first-order transition, consistent with previous numerical studies.

description: We study the ultraviolet to far-infrared (hereafter UV-to-IR) SEDs of a sample of intermediate redshift (0.2 < z < 0.7) UV-selected galaxies from the ELAIS-N1 and ELAIS-N2 fields by fitting a multi-wavelength dataset to a library of GRASIL templates. Star formation related properties of the galaxies are derived from the library of models by using the Bayesian statistics. We find a decreasing presence of galaxies with low attenuation and low total luminosity as redshift decreases, which does not hold for high total luminosity galaxies. In addition the dust attenuation of low mass galaxies increases as redshift decreases, and this trend seems to disappear for galaxies with M* > 10^11 M_sun. This result is consistent with a mass dependent evolution of the dust to gas ratio, which could be driven by a mass dependent efficiency of star formation in star forming galaxies. The specific star formation rates (SSFR) decrease with increasing stellar mass at all redshifts, and for a given stellar mass the SSFR decreases with decreasing redshift. The differences in the slope of the M*--SSFR relation found between this work and others at similar redshift could be explained by the adopted selection criteria of the samples which, for a UV selected sample, favours blue, star forming galaxies.

description: Thomas and Lindner (2014, Phys.Rev.Lett.) defined an asymptotic phase for stochastic oscillators as the angle in the complex plane made by the eigenfunction, having a complex eigenvalue with a least negative real part, of the backward Kolmogorov (or stochastic Koopman) operator. We complete the phase-amplitude description of noisy oscillators by defining the stochastic isostable coordinate as the eigenfunction with the least negative nontrivial real eigenvalue. Our results suggest a framework for stochastic limit cycle dynamics that encompasses noise-induced oscillations.
Breaking a quantum key distribution system through a timing side channel

description: The security of quantum key distribution relies on the validity of quantum mechanics as a description of nature and on the non-existence of leaky degrees of freedom in the practical implementations. We experimentally demonstrate how, in some implementations, timing information revealed during public discussion between the communicating parties can be used by an eavesdropper to undetectably access a significant portion of the ``secret'' key.

object tracking detection

description: Tracking Multiple Objects and Prioritizing them can be an expensive operation. In a real-world scenario where, for example, many cars are being tracked coming through a highway by a certain characteristic such as car color this leads to one needing to process them efficiently, especially when the cars are quickly coming in and out of the screen. This research aims to see if there is an optimal way to process and sort many tracked objects efficiently; thus, the purpose of this Thesis Research Project is to answer the central question of: “whether the AVL self-balancing Binary Search Tree can be used for optimization of data processing from a Computer Vision Robotics camera source?” The Tree data structure is used in many areas of Computer Science and Software Engineering; there are different variations, each with different characteristics for various applications. This research uses the AVL (Adelson-Velsky and Landis) self-balancing binary search tree to see differences in Asymptotic Runtime for insert and traversal operations. A number of specialized hardwares and softwares will be used to conduct this research with rigorous test benchmarking to get the most accurate results. The results of this Thesis Research Project shows the AVL tree being stable with the complexity running time maintaining O (logn) for the tested operations with varying batch data sizes making it feasible for post-processing use in Computer Vision and other industry applications.
