Creators: name: Straker, Justin

Publisher: name: The University of British Columbia
Year: 2010

description: Teck Coal operates five metallurgical coal mines in the Elk Valley of southeast B.C.: Fording River, Greenhills, Line Creek, Elkview, and Coal Mountain Operations. Along with their sister mine in Alberta, Cardinal River, these mines make Teck the second-largest exporter of coking coal in the world. Teck Coal also has two non-operating mines, Quintette and Bullmoose, in northeast B.C. Reclamation and reclamation research has been conducted on some of these sites since the beginning of modern mine development in the late 1960s. Together, these mines have reclaimed almost 7,000 hectares of land. In 2010, Teck Coal initiated a project to compile data and interpretations on reclamation research conducted to date on their eight open-pit metallurgical coal mining operations, with the objective of producing a synthesis of the current state of knowledge with respect to reclamation techniques on these sites. This synthesis focuses on the following two questions: 1. What has Teck Coal learned in over 40 years of reclamation at its operations? or “What do we know?” and 2. What are the future challenges or needs with respect to reclamation research and practice? or “What do we need to know?” This paper will present highlights from the Teck Coal Reclamation Research synthesis document, particulary with respect to the two questions above.

description: We show that gravitational radiation is produced quite efficiently in interactions of classical waves created by resonant decay of a coherently oscillating field. For simple models of chaotic inflation in which the inflaton interacts with another scalar field, we find that today's ratio of energy density in gravitational waves per octave to the critical density of the universe can be as large as 10^{-12} at the maximal wavelength of order 10^{5} cm. In the pure $λϕ^4$ model, the maximal today's wavelength of gravitational waves produced by this mechanism is of order 10^6 cm, close to the upper bound of operational LIGO and TIGA frequencies. The energy density of waves in this model, though, is likely to be well below the sensitivity of LIGO or TIGA at such frequencies. We discuss possibility that in other inflationary models interaction of classical waves can lead to an even stronger gravitational radiation background.

Rotation Period Evolution in Low-Mass Binary Stars: The Impact of Tidal Torques and Magnetic Braking

description: We examine how tides, stellar evolution, and magnetic braking shape the rotation period (P$_{rot}$) evolution of low-mass stellar binaries up to orbital periods (P$_{orb}$) of 100 d across a wide range tidal dissipation parameters using two common equilibrium tidal models. We find that many binaries with P$_{orb} < 20$ d tidally lock, and most with $P_{orb} < 4$ d tidally lock into synchronous rotation on circularized orbits. At short P$_{orb}$, tidal torques produce a population of fast rotators that single-star only models of magnetic braking fail to produce. In many cases, we show that the competition between magnetic braking and tides produces a population of subsynchronous rotators that persists for Gyrs, even in short P$_{orb}$ binaries, qualitatively reproducing the subsynchronous eclipsing binaries (EBs) discovered in the Kepler field by Lurie et al. (2017). Both equilibrium tidal models predict that binaries can tidally-interact out to P$_{orb} \approx 80$ d, while the Constant Phase Lag tidal model predicts that binaries can tidally lock out to P$_{orb} \approx 100$ d. Tidal torques often force the P$_{rot}$ evolution of stellar binaries to depart from the long-term magnetic braking-driven spin down experienced by single stars, revealing that P$_{rot}$ is not be a valid proxy for age in all cases, i.e. gyrochronology can underpredict ages by up to $300\%$ unless one accounts for binarity. We suggest that accurate determinations of orbital eccentricties and P$_{rot}$ can be used to discriminate between which equilibrium tidal models best describes tidal interactions in low-mass binary stars.

description: We study the effects of the leading irrelevant perturbations on chiral symmetry breaking in the effective $QED_3$ theory of d-wave superconductor-insulator transition in underdoped cuprates. For weak symmetry breaking, the effect of a perturbation on energies of various insulating states can be classified according to its engineering dimension in the maximally symmetric theory. Considering the velocity anisotropy, repulsive interactions, and higher order derivatives we show that the insulating state with the lowest energy is the spin density wave.

A length operator for canonical quantum gravity

Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We construct an operator that measures the length of a curve in four-dimensional Lorentzian vacuum quantum gravity. We work in a representation in which a $SU(2)$ connection is diagonal and it is therefore surprising that the operator obtained after regularization is densely defined, does not suffer from factor ordering singularities and does not require any renormalization. We show that the length operator admits self-adjoint extensions and compute part of its spectrum which like its companions, the volume and area operators already constructed in the literature, is purely discrete and roughly is quantized in units of the Planck length. The length operator contains full and direct information about all the components of the metric tensor which faciliates the construction of a new type of weave states which approximate a given classical 3-geometry.

Information Relevance for Informed Consent to Clinical Trials: Patients, Advisors, and Clinicians

Publisher: name: Carnegie Mellon University
Year: 2019
Subjects: subject: 220302 Decision Theory
subject: FOS: Philosophy, ethics and religion

description: This dissertation investigates patient and advisor information preferences regarding informed consent for clinical trials, and provider understanding of those preferences. The revised Common Rule requirements and their focus on identifying key information in consent make such investigation especially timely. This dissertation extends the literature on these topics by including, along with legal surrogates, advisors who lack legal decision making authority (“pure advisors”). Study 1 replicates and extends previous work by using patients’ and advisors’ choices of relevant information from a consent form to shorten the form. The results indicate that this produces a substantially shorter form that is broadly similar across groups, while also highlighting some ways in which surrogates’ preferences seem to diverge from those of patients and advisors, in that they choose less information from the original form and feel somewhat more negatively regarding trial-related decisions. Study 2 tests the shortened form against the original form, and finds that the revised form does not cause decreases in trial comprehension or engagement. However, participants, particularly surrogates, seem to feel less positively toward the shortened form. This result and some stakeholder group differences in decisions captured in this study point toward the importance of both the status quo and group membership to interpretation of informed consent and the clinical trial process. Study 3 evaluates medical providers’ ability to predict patient preferences for informed consent content, and finds that while they tend to overestimate patients’ desire for many types of information on a sentence level, they have a better understanding of the general issues patients find important in clinical research enrollment, though there is some evidence for systematic misunderstanding. Extensions and applications of these studies have the potential to improve the informed consent process for all stakeholder groups discussed.
Differential Interferometric Signatures of Close Binaries of Supermassive Black Holes in Active Galactic Nuclei

description: In the present paper, we explore opportunities of applying the GRAVITY at the Very Large Telescope Interferometry (VLTI) with unprecedented spatial resolution to identify close binaries of supermassive black holes (CB-SMBHs) in active galactic nuclei (AGNs). Each SMBH is assumed to be separately surrounded by their own broad-line regions (BLRs) composed of clouds with virialized motion. Composition of the binary orbital motion and the virial motion of clouds in each BLR determines the projected velocity fields and hence differential phase curves, which are obviously different from that of a single BLR. We calculate emission line profiles and differential phase curves of CB-SMBHs for the GRAVITY. For the simplest case where angular momentums of two BLRs and orbital motion are parallel, a phase plateau generally appears in the phase curves. For other combinations of the angular momentum, the plateau is replaced by new peaks and valleys variously depending on the situations. Given a combination, phase curves are also sensitive to changes of parameters of CB-SMBHs. All these features are easily distinguished from the well-known $S$-shaped phase curves of a single BLR so that the GRAVITY is expected to reveal signals of CB-SMBH from candidates of AGNs. With joint analysis of observations of reverberation mapping campaigns, we can reliably identify CB-SMBHs, and measure their orbital parameters in the meanwhile. This independent measurement of the orbital parameters also has implications to analysis of Pulsar Timing Array (PTA) observations for properties of low-frequency gravitational waves in future.

description: On March 26th, 2019, at the Rencontres de Moriond QCD conference, the LHCb Collaboration reported the observation of three new pentaquarks, namely $P_c(4312)$, $P_c(4440)$ and $P_c(4457)$, which are consistent with the loosely bound molecular hidden-charm pentaquark states composed of an S-wave charmed baryon $Σ_c$ and an S-wave anti-charmed meson ($\bar{D}, \bar{D}^*$). In this work, we present a direct calculation by the one-boson-exchange (OBE) model and demonstrate explicitly that the $P_c(4312)$, $P_c(4440)$ and $P_c(4457)$ do correspond to the loosely bound $Σ_c\bar{D}$ with $(I=1/2,J^P=1/2^-)$, $Σ_c\bar{D}^*$ with $(I=1/2,J^P=1/2^-)$ and $Σ_c\bar{D}^*$ with $(I=1/2,J^P=3/2^-)$, respectively.

Tidal disruptions by rotating black holes: effects of spin and impact parameter

description: We present the results of relativistic smoothed particle hydrodynamics simulations of tidal disruptions of stars by rotating supermassive black holes, for a wide range of impact parameters and black hole spins. For deep encounters, we find that: relativistic precession creates debris geometries impossible to obtain with the Newtonian equations; part of the fluid can be launched on plunging orbits, reducing the fallback rate and the mass of the resulting accretion disc; multiple squeezings and bounces at periapsis may generate distinctive X-ray signatures resulting from the associated shock breakout; disruptions can occur inside the marginally bound radius, if the angular momentum spread launches part of the debris on non-plunging orbits. Perhaps surprisingly, we also find relativistic effects important in partial disruptions, where the balance between self-gravity and tidal forces is so precarious that otherwise minor relativistic effects can have decisive consequences on the stellar fate. In between, where the star is fully disrupted but relativistic effects are mild, the difference resides in a gentler rise of the fallback rate, a later and smaller peak, and longer return times. However, relativistic precession always causes thicker debris streams, both in the bound part (speeding up circularization) and in the unbound part (accelerating and enhancing the production of separate transients). We discuss various properties of the disruption (compression at periapsis, shape and spread of the energy distribution) and potential observables (peak fallback rate, times of rise and decay, duration of super-Eddington fallback) as a function of the impact parameter and the black hole spin.

Year: 2010

description: After a very short history of mining (1964 to 1966), the Mount Washington copper mine has been a major source of acid rock drainage entering the Tsolum River near Courtenay, BC. Previous remediation projects have been partially successful at controlling the ARD generation at the site and treating the copper bearing discharge from the site (Pyrrhotite Creek). The current project includes placement of a bituminous liner over the North Pit, covering the liner with soil for revegetation, improvement of the surface water diversions and, if necessary, treatment of the drainage from under the cover while groundwater recovers. The Ministry of Energy, Mines and Petroleum Resources retained Quantum Environmental, SRK Consultants (Canada) Inc and Stantec to carry out the work. The Tsolum River Partnership, a coalition of community, industry and government were also involved in the planning and implementation of this project The project is ongoing. Site preparation, liner installation and partial placement of the soil cover were completed during the summer of 2009. The placement of the remaining soil cover on top of the liner and revegetation of the site will be completed during the summer of 2010. Post-construction monitoring will be conducted by the Tsolum River Restoration Society and the Ministry of Environment for at least two years to determine if lime treatment will be required.

description: Techniques developed for device-independent characterizations allow one to certify certain physical properties of quantum systems without assuming any knowledge of their internal workings. Such a certification, however, often relies on the employment of device-independent witnesses catered for the particular property of interest. In this work, we consider a one-parameter family of multipartite, two-setting, two-outcome Bell inequalities and demonstrate the extent to which they are suited for the device-independent certification of genuine many-body entanglement (and hence the entanglement depth) present in certain well-known multipartite quantum states, including the generalized Greenberger-Horne-Zeilinger (GHZ) states with unbalanced weights, the higher-dimensional generalizations of balanced GHZ states, and the $W$ states. As a by-product of our investigations, we have found that, in contrast with well-established results, provided trivial qubit measurements are allowed, full-correlation Bell inequalities can also be used to demonstrate the nonlocality of weakly entangled unbalanced-weight GHZ states. Besides, we also demonstrate how two-setting, two-outcome Bell inequalities can be constructed, based on the so-called GHZ paradox, to witness the entanglement depth of various graph states, including the ring graph states, the fully connected graph states, and some linear graph states, etc.

The asymptotic for modified Schwarzschild solution is obtained, as a decomposition in parameter $L \approx 10^{-32}$ cm. It is shown, that singularity at $r = 0$ is absent, being replaced by a `ball of matter' with finite dimensions, such that density of matter is of order of magnitude of the Planck's density. Another solution of the same symmetry is obtained, corresponding to a closed space of finite volume of order $L^3$.

description: This research evaluates the role of participatory planning mechanisms such as Community Boards (CBs) and public hearings through two case studies involving environmental justice advocacy in the South Bronx. By tracing the theoretical and political underpinnings of the Postreform era of planning I contend that the results of the movement to democratize the planning process as encoded in the 1975 and 1989 charter reforms were severely flawed because it did not meaningfully devolve power to citizens - an observation often overlooked by contemporary academics. In the intervening years the agency afforded to communities by these processes has developed unevenly: while some wealthy neighborhoods have wielded their CB to effectively achieve their goals, others like those in the South Bronx have found their priorities repeatedly ignored, overridden, or watered down. Through a thorough examination of the economic development deal which resulted in FreshDirect moving their headquarters to a site in Port Morris and the Sheridan Expressway redesign I develop a theory of co-optation that instrumentalizes participation in order to launder state power to private interests, signaled by a retreat by activists from the official venues of the planning process in favor of ad-hoc advocacy groups.

description: There is widespread agreement among researchers, policy experts, and community advocates that the United States’ mass incarceration system is a policy failure. Despite bipartisan consensus and sporadic reform attempts, the policies and systems ravaging low-income families and communities of color remain largely intact. Formerly incarcerated people have been driving the social movement to dismantle mass incarceration since the movement’s inception, yet their advocacy efforts and creation of alternative programmatic and policy approaches have only recently been acknowledged and documented and have yet to be implemented widely. Through this study, I aimed to fill these gaps in knowledge about the advocacy work of women impacted by the justice system by documenting the ethos, practices, and strategies of Theater for Social Change (TSC), a performance arts-based advocacy group composed of formerly incarcerated women in service of justice system transformation. Using action research methodology, I employed dialogic and iterative processes, in partnership with TSC, to develop interview and focus group protocols and analyze data. I also undertook a thematic analysis of post-performance audience discussions, as well as the scenes and monologues created by the ensemble over the years. This research project found that the ensemble way of working—defined by Radosavljević (2013) as “collective, creative, and collaborative”—enabled TSC to develop and model the type of caring and self-organized community and capacity development, per Nixon et al. (2008), that they envision for currently and formerly incarcerated women and their families and communities to create conditions for a just and equitable society. The ensemble way of working nurtured a sisterhood and enabled the exploration of individual and shared experiences of the trauma of incarceration, as well as overcoming systemic inequalities through higher education and career success in a safe and supportive space. Performing scenes and monologues developed from personal stories allows TSC to control its advocacy messages, challenge stereotypes, and create new narratives about the worth of formerly incarcerated people. Theater and post-performance discussions also enable ensemble members to model and employ their multilevel expertise: personal experience navigating the justice system; professional expertise in reentry, mental health and human services; and advocacy leadership.

description: An elastic membrane with embedded nematic molecules is considered as a model of anisotropic fluid membrane with internal ordering. By considering the geometric coupling between director field and membrane curvature, the nematic texture is shown to induce anisotropic stresses additional to Canham-Helfrich elasticity. Building upon differential geometry, analytical expressions are found for the membrane stress and torque induced by splaying, twisting and bending of the nematic director as described by the Frank energy of liquid crystals. The forces induced by prototypical nematic textures are visualized on the sphere and on cylindrical surfaces.

description: Stabilization of oxidized sulphidic mine waste deposits with alkaline by-products could be a way of controlling ARD. Mixtures of alkaline by-products (10% by volume) and oxidized waste rock have been studied during six months in 30 L experimental drums. Alkaline by-products are: lime mud (LM), green liquor dreg (GLD), lime kiln dust (LKD), LD slag (LD), water work granules (WWG), carbonized fly ash (FAE) and fresh fly ash (FAF). The experiments are fed with water once a week to imitate natural precipitation. pH of the reference (no alkaline amendment) is below 3 and trace metal concentrations are 2000 mg/l, 4 mg/l and 1 mg/l for Zn, Cd and Pb respectively. LKD, LM and LD amended systems (pH 6.7-7.5) are the most efficient for Cd- and Zn-removal (reduction at least 99 % compared to the reference), while GLD (tap pH 6.5) is the most efficient for Pb-removal (99 % reduction compared to the reference). FAE amended system only reaches pH around 5 and accordingly trace metal reduction is rather low. Geochemical simulations using PHREEQC indicate equilibrium with otavite and smithsonite in the WWG and GLD systems, whereas cerrusite is at equilibrium in the LKD, WWG and GLD systems.

description: We summarize results from a study of spherically symmetric collapse of a {\it charged} (complex) massless scalar-field \cite{Hod}. We present an analytic argument which conjecture the generalization of the mass-scaling relation and echoing phenomena, originally discovered by Choptuik, for the {\it charged} case. Furthermore, we study the behaviour of the self-similar critical solution under {\it external} perturbations -- addition of a cosmological constant $Λ$ and a charge-conjugation $e$. Finally, we study the scaling-relation of the black-hole charge. Using an analytic argument we conjecture that black-holes of infinitesimal mass are neutral or obey the relation $Q_{BH} \ll M_{BH}$. We verify our predictions with numerical results.

description: We provide descriptions for the moduli spaces $\text{Rep}(Γ, PU(m))$, where $Γ$ is any finitely generated abelian group and $PU(m)$ is the group of $m\times m$ projective unitary matrices. As an application we show that for any connected CW-complex $X$ with $π_1(X)\cong \mathbf{Z}^n$, the natural map $π_0(\text{Rep}(π_1(X), PU(m)))\to [X, BPU(m)]$ is injective, hence providing a complete enumeration of the isomorphism classes of flat principal $PU(m)$-bundles over $X$.

description: May the $\mathit{triforce}$ be the 3-uniform hypergraph on six vertices with edges $\{123',12'3,1'23\}$. We show that the minimum triforce density in a 3-uniform hypergraph of edge density $δ$ is $δ^{4-o(1)}$ but not $O(δ^4)$. Let $M(δ)$ be the maximum number such that the following holds: for every $ε> 0$ and $G = \mathbb{F}_2^n$ with $n$ sufficiently large, if $A \subseteq G \times G$ with $A \ge δ|G|^2$, then there exists a nonzero "popular difference" $d \in G$ such that the number of "corners" $(x,y), (x+d,y), (x,y+d) \in A$ is at least $(M(δ) - ε)|G|^2$. As a corollary via a recent result of Mandache, we conclude that $M(δ) = δ^{4-o(1)}$ and $M(δ) = ω(δ^4)$. On the other hand, for $0 < δ< 1/2$ and sufficiently large $N$, there exists $A \subseteq [N]^3$ with $|A|\geδN^3$ such that for every $d \ne 0$, the number of corners $(x,y,z), (x+d,y,z),(x,y+d,z),(x,y,z+d) \in A$ is at most $δ^{c \log (1/δ)} N^3$. A similar bound holds in higher dimensions, or for any configuration with at least 5 points or affine dimension at least 3.

description: We compare different methods used for non-perturbative calculations in strongly interacting fermionic systems. Mean field theory often shows a basic ambiguity related to the possibility to perform Fierz transformations. The results may then depend strongly on an unphysical parameter which reflects the choice of the mean field, thus limiting the reliability. This ambiguity is absent for Schwinger-Dyson equations or fermionic renormalization group equations. Also renormalization group equations in a partially bosonized setting can overcome the Fierz ambiguity if the truncation is chosen appropriately. This is reassuring since the partially bosonized renormalization group approach constitutes a very promising basis for the explicit treatment of condensates and spontaneous symmetry breaking even for situations where the bosonic correlation length is large.

Chiral current-phase relation of topological Josephson junctions: A signature of the $4π$-periodic Josephson effect

description: The $4π$-periodic Josephson effect is an indicator of Majorana zero modes and a ground-state degeneracy which are central to topological quantum computation. However, the observability of a $4π$-periodic Josephson current-phase relation (CPR) is hindered by the necessity to fix the fermionic parity. As an alternative to a $4π$-periodic CPR, this paper proposes a chiral CPR for the $4π$-periodic Josephson effect. This is a CPR of the form $J(ϕ) \propto C \, |\sin(ϕ/2)|$, describing a unidirectional supercurrent with the chirality $C= \pm 1$. Its non-analytic dependence on the Josephson phase difference $ϕ$ translates into the $4π$-periodic CPR $J(ϕ) \propto \sin(ϕ/2)$. The proposal requires a spin-polarized topological Josephson junction which is modeled here as a short link between spin-split superconducting channels at the edge of a two-dimensional topological insulator. In this case, $C$ coincides with the Chern number of the occupied spin band of the topological insulator. The paper details three scenarios of achieving a chiral CPR: By only Zeeman-like splitting, by Zeeman splitting combined with bias currents, and by an external out-of-plane magnetic field.

A theory of average response to large jump perturbations

Year: 2019
Subjects: subject: Mathematical Physics (math-ph)

description: A key feature of the classical Fluctuation Dissipation theorem is its ability to approximate the average response of a dynamical system to a sufficiently small external perturbation from an appropriate time correlation function of the unperturbed dynamics of this system. In the present work, we examine the situation where the state of a nonlinear dynamical system is perturbed by a finitely large, instantaneous external perturbation (jump) -- for example, the Earth climate perturbed by an extinction level event. Such jump can be either deterministic or stochastic, and in the case of a stochastic jump its randomness can be spatial, or temporal, or both. We show that, even for large instantaneous jumps, the average response of the system can be expressed in the form of a suitable time correlation function of the corresponding unperturbed dynamics. For stochastic jumps, we consider two situations: one where a single spatially random jump of a system state occurs at a predetermined time, and another where jumps occur randomly in time with small space-time dependent statistical intensity. For all studied configurations, we compute the corresponding average response formulas in the form of suitable time correlation functions of the unperturbed dynamics. Some efficiently computable approximations are derived for practical modeling scenarios.
