description: The powerful group theoretical formalism of potential algebras is extended to non-Hermitian Hamiltonians with real eigenvalues by complexifying so(2,1), thereby getting the complex algebra sl(2,\C) or $A_1$. This leads to new types of both PT-symmetric and non-PT-symmetric Hamiltonians.

description: The statistical-mechanical origin of the Bekenstein-Hawking entropy $S^{BH}$ in the induced gravity is discussed. In the framework of the induced gravity models the Einstein action arises as the low energy limit of the effective action of quantum fields. The induced gravitational constant is determined by the masses of the heavy constituents. We established the explicit relation between statistical entropy of constituent fields and black hole entropy $S^{BH}$.

The two-phase approximation for black hole collisions: Is it robust?

description: Recently Abrahams and Cook devised a method of estimating the total radiated energy resulting from collisions of distant black holes by applying Newtonian evolution to the holes up to the point where a common apparent horizon forms around the two black holes and subsequently applying Schwarzschild perturbation techniques . Despite the crudeness of their method, their results for the case of head-on collisions were surprisingly accurate. Here we take advantage of the simple radiated energy formula devised in the close-slow approximation for black hole collisions to test how strongly the Abrahams-Cook result depends on the choice of moment when the method of evolution switches over from Newtonian to general relativistic evolution. We find that their result is robust, not depending strongly on this choice.

description: Let H be a self-adjoint operator bounded below by 1, and let V be a small form perturbation such that RVS has finite norm, where R is the resolvent at zero to the power 1/2 +epsilon, and S is the resolvent to the power 1/2-epsilon. Here, epsilon lies between 0 and 1/2. If the Gibbs state defined by H is sufficiently regular, we show that the free energy is an analytic function of V in the sense of Frechet, and that the family of density operators defined in this way is an analytic manifold modelled on a Banach space.

description: Motivated by a recent experimental observation of superconductivity in the Al-Zn-Mg quasicrystal, we study the low-temperature behavior of electrons moving in the quasiperiodic potential of the Ammann-Beenker tiling in the presence of a local attraction. We employ the Bogoliubov-de Gennes approach for approximants of different sizes and determine the local pairing amplitude $Δ_{i}$ as well its spatial average, $Δ_{0}$, the superconducting order parameter. Due to the lack of periodicity of the octagonal tiling, the resulting superconducting state is inhomogeneous, but we find no evidence of the superconductivity islands, as observed in disordered systems, with $Δ_{i}\rightarrow0$ at $T_{c}$ for all sites. In the weak-coupling regime, we find that the superconducting order parameter depends appreciably on the approximant size only if the Fermi energy sits at a pseudogap in the noninteracting density of states, with $Δ_{0}$ decreasing as the system size increases. These results are in line with the experimental observations for the Al-Zn-Mg quasicrystal, and they suggest that, despite their electronic structure, quasicrystals are prone to display conventional BCS-like superconductivity.

description: Even though little is known about the quantum entropy cone for $N\geq4$ subsystems, holographic techniques allow one to get a handle on the subspace of entropy vectors corresponding to states with gravity duals. For static spacetimes and $N$ boundary subsystems, this space is a convex polyhedral cone known as the holographic entropy cone $\mathcal{C}_N$ for $N$ regions. While an explicit description of $\mathcal{C}_N$ was accomplished for all $N\leq4$ in the initial study, the information given about larger $N$ was only partial already for $\mathcal{C}_5$. This letter provides a complete construction of $\mathcal{C}_5$ by exhibiting graph models for every extreme ray orbit generating the cone defined by all proven holographic entropy inequalities for $N=5$. The question of whether there exist additional inequalities for $5$ parties is thus settled with a negative answer. The conjecture that $\mathcal{C}_5$ coincides with the analogous cone for dynamical spacetimes is supported by demonstrating that the information quantities defining its facets are primitive.

description: Results are reported for a search for supersymmetry in final states with photons and missing transverse momentum in proton-proton collisions at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb$^{-1}$ collected at a center-of-mass energy of 13 TeV using the CMS detector. The results are interpreted in the context of models of gauge-mediated supersymmetry breaking. Production cross section limits are set on gluino and squark pair production in this framework.

City planning

description: Climate scientists predict that extreme weather events will increase in intensity and frequency as the global climate changes. Extreme weather such as Hurricane Sandy has shown the importance of planning for climate change adaptation, but few public transit agencies have developed their own adaptation plans. As demonstrated by Hurricane Sandy’s effect on transportation infrastructure in the New York City region, it is important for city officials to plan for extreme weather events and also for protecting infrastructure from the risk of flooding. The public transit agencies of nine cities were studied with a qualitative evaluation to determine the strength of their climate change planning documents. Only four transit agencies had some type of climate change document, and none of the agencies have official climate change plans. Overall, transit agencies are not developing clear goals for climate change adaptation. Possible reasons for this are a lack of funding and the perception of a lack of urgency. The Metropolitan Transportation Authority of New York’s sustainability report emerged as a model for other agencies’ adaptation planning efforts due to its level of detail.

Low-income housing--Government policy

description: City governments across the United States are struggling to keep housing and services affordable for lower-income households as neighborhood conditions improve in previously disinvested areas. Despite considerable fiscal and political constraints, numerous cities are tackling this challenge through policy tools that protect the stock of low-cost housing and support lower-income residents’ ability to remain in place when reinvestment raises the threat of displacement. Drawing on a framework informed by theories of equity planning, the Just City, and redistributive policy action, this study examines how cities are mitigating displacement in neighborhoods at risk of gentrification and analyzes the conditions that motivate, facilitate, and shape their policy responses. Data were collected through an original survey of housing, planning, and community development officials, a systematic review of policy documents, and semi-structured interviews with city officials and community advocates. Through sequential quantitative and qualitative analyses, I show that although city governments possess and are using diverse tools to create more equitable outcomes in neighborhoods at risk of gentrification, their tendency to delay action until market appreciation is advanced, dependence on market-based tools amid fiscal constraint, and need to balance neighborhood-based and city-wide goals weaken their capacity to tackle displacement. This study concludes that proactive approaches that address reinvestment and long-term affordability concurrently would minimize the tensions associated with the timing, form, and scale of intervention. Cities’ demonstrated responsiveness to community organizing suggests one key channel through which such a policy shift could be activated.
Constraints on Mediator Coupled to Heavy Quarks from LHC Data

description: We apply LHC data to constrain a simplified extension of the Standard Model containing a new spin-1 mediator $R$, which does not couple to first generation quarks, and a spinor dark matter particle $χ$. We recast ATLAS and CMS searches for final states containing one or more jet(s) + missing $E_T$, with or without $b$ tags, as well as searches for di-jet resonances with $b$ or $t$ tagging. We find that LHC constraints on the axial vector couplings of the mediator are always stronger than the unitarity bound, which scales like $m_R/m_t$. If $R$ has a sizable invisible branching ratio, the strongest LHC bound on both vector couplings and axial vector coupling comes from a di-jet + missing $E_T$ search with or without double $b$ tag. These bounds are quite strong for $m_R < 1$ TeV, even though we have switched off all couplings to valence quarks. Searches for a di-jet resonance with double $b$ tag lead to comparable bounds with the previous results even if $R \rightarrow χ\bar χ$ decays are allowed; these are the only sensitive LHC searches if the invisible branching ratio of $R$ is very small or zero.

description: We investigate the influence of dissipation on one- and two-qubit rotations in coupled semiconductor quantum dots, using a (pseudo) spin-boson model with adiabatically varying parameters. For weak dissipation, we solve a master equation, compare with direct perturbation theory, and derive an expression for the `fidelity loss' during a simple operation that adiabatically moves an electron between two coupled dots. We discuss the possibility of visualizing coherent quantum oscillations in electron `pump' currents, combining quantum adiabaticity and Coulomb blockade. In two-qubit spin-swap operations where the role of intermediate charge states has been discussed recently, we apply our formalism to calculate the fidelity loss due to charge tunneling between two dots.

Closure of the Lumby Quinto Site
Creators: name: Ames, S.E.
Publisher: name: The University of British Columbia
Year: 2012

description: The Lumby Quinto Mine Site is located approximately 27 km east of Vernon, BC. It is built on the side of Saddle Mountain and overlooks the town of Lumby. The Quinto Mine was an “abandoned underground mine” which has a long history dating back to 1900. No mining or exploration activities have occurred on the property since 1994. The site was acquired by Consolidated Thompson in 2008. The new owner determined that the site needed to be closed. When the last operation closed, everything was left including buildings and milling equipment. The site also included adits, two small tailings storage facilities, a water storage pond, ore stockpiles, and waste rock. The ponds were located on the floodplain of Bessette Creek. Additional drilling was done on the floodplain for metal analysis and a bat study was carried out for the adits. Based on the findings of the detailed investigation, a closure plan was developed. This involved removal of buildings, backfilling of the adits with waste rock and backfilling the ponds. The ore was removed from the site. Material was sorted on site and recycled, as much as possible. The site was closed using local demolition and earthworks operators and reclaimed. All closure activities were monitored. The site was closed in 2011.

description: Since 1967 Saint Paul, Minnesota has allocated municipal bonds through a participatory mechanism called the Capital Improvement Budget Process. In this process a representative from each neighborhood sits on a task force and a committee to help decide which projects should be allocated funding. Projects eligible for funding fall into three categories: community facilities, streets and utilities, and real estate development. This thesis examines how funding has been allocated by neighborhood (district council) and census tract between 1990 and 2005. Furthermore, the paper examines if racially-concentrated areas of poverty (RCAP) received less funding than other areas. Through a quantitative analysis it was found that Saint Paul, MN currently allocates the majority of its municipal bonds to the downtown core and a few surrounding neighborhoods.

description: We report on the buckling and subsequent collapse of orthotropic elastic spherical shells under volume and pressure control. Going far beyond what is known for isotropic shells, a rich morphological phase space with three distinct regimes emerges upon variation of shell slenderness and degree of orthotropy. Our extensive numerical simulations are in agreement with experiments using fabricated polymer shells. The shell buckling pathways and corresponding strain energy evolution are shown to depend strongly on material orthotropy. We find surprisingly robust orthotropic structures with strong similarities to stomatocytes and tricolpate pollen grains, suggesting that the shape of several of Nature's collapsed shells could be understood from the viewpoint of material orthotropy.

description: Purpose: The purpose of this tutorial is to describe a tool and a procedure to support the collection and qualitative manual analysis of aided language samples in Spanish.Method: The Protocol for the Analysis of Aided Language Samples in Spanish (PAALSS) was developed from the present knowledge of Spanish language acquisition, and established procedures for the analysis of aided language samples. A draft version of PAALSS was distributed among 476 augmentative and alternative communication (AAC) service providers in Argentina, Chile, Costa Rica, Mexico, and the United States, who provided feedback on their usability and applicability. The clinical application of PAALSS is illustrated through the analysis of three different language samples of an 8-year-old child who uses aided AAC.Results: The use of PAALSS allowed the child’s educational team to document the child’s strengths and to set therapy goals to address her needs, such as increasing the length of her utterances and other structures essential for grammaticalization including articles, adjectives, adverbs, diminutives, morphemes for gender and number, prepositions, and personal pronouns.Conclusions: PAALSS can be used to describe the expressive language use of children who use aided AAC in Spanish and are in the early stages of language development. PAALSS can also be used as a guide to set goals for and measure outcomes of language therapy along four domains of expressive language including vocabulary, morphology, grammatical complexity, and syntax.

description: We show that under variation of moduli fields $ϕ$ the first law of black hole thermodynamics becomes $dM = {κdA\over 8π} + ΩdJ + ψdq + χdp - Σdϕ$, where $Σ$ are the scalar charges. We also show that the ADM mass is extremized at fixed $A$, $J$, $(p,q)$ when the moduli fields take the fixed value $ϕ_{\rm fix}(p,q)$ which depend only on electric and magnetic charges. It follows that the least mass of any black hole with fixed conserved electric and magnetic charges is given by the mass of the double-extreme black hole with these charges. Our work allows us to interpret the previously established result that for all extreme black holes the moduli fields at the horizon take a value $ϕ= ϕ_{\rm fix}(p,q)$ depending only on the electric and magnetic conserved charges: $ ϕ_{\rm fix}(p,q)$ is such that the scalar charges $Σ( ϕ_{\rm fix}, (p,q))=0$.

description: The galaxy distributions along the line-of-sight are significantly contaminated by the uncertainty on redshift measurements obtained through multiband photometry, which makes it difficult to get cosmic distance information measured from baryon acoustic oscillations, or growth functions probed by redshift distortions. We investigate the propagation of the uncertainties into large scale clustering by exploiting all known estimators, and propose the wedge approach as a promising analysis tool to extract cosmic distance information still remaining in the photometric galaxy samples. We test our method using simulated galaxy maps with photometric uncertainties of $σ_{0} =\left(0.01, 0.02, 0.03\right)$. The measured anisotropy correlation function $ξ$ is binned into the radial direction of $s$ and the angular direction of $μ$, and the variations of $ξ(s,μ)$ with perpendicular and radial cosmic distance measures of $D_A$ and $H^{-1}$ are theoretically estimated by an improved RSD model. Although the radial cosmic distance $H^{-1}$ is unable to be probed from any of the three photometric galaxy samples, the perpendicular component of $D_A$ is verified to be accurately measured even after the full marginalisation of $H^{-1}$. We measure $D_A$ with approximately 6% precision which is nearly equivalent to what we can expect from spectroscopic DR12 CMASS galaxy samples.

description: We examine the minimization of information entropy for measures on the phase space of bounded domains, subject to constraints that are averages of grand canonical distributions. We describe the set of all such constraints and show that it equals the set of averages of all probability measures absolutely continuous with respect to the standard measure on the phase space (with the exception of the measure concentrated on the empty configuration). We also investigate how the set of constrains relates to the domain of the microcanonical thermodynamic limit entropy. We then show that, for fixed constraints, the parameters of the corresponding grand canonical distribution converge, as volume increases, to the corresponding parameters (derivatives, when they exist) of the thermodynamic limit entropy. The results hold when the energy is the sum of any stable, tempered interaction potential that satisfies the Gibbs variational principle (e.g.~Lennard-Jones) and the kinetic energy. The same tools and the strict convexity of the thermodynamic limit pressure for continuous systems (valid whenever the Gibbs variational principle holds) give solid foundation to the folklore local homeomorphism between thermodynamic and macroscopic quantities.

description: Supplies of topsoil are often limited for use in mine reclamation activities; it may be necessary to build soils using locally available substrates. Revegetation test plots were established at Huckleberry Mine, Houston, B.C., to investigate the performance of seven native plant species treatments on stockpiled topsoils amended with (or without) non-acid generating (NAG) sand (obtained from desulphurized copper tailings) and NPK fertilizer. Seeding treatments (single or mixed species) consisted of species native to the mine site (local genotype) obtained from commercial seed (mixed genotype). Soil sampling and vegetation monitoring were conducted during two growing seasons. NAG sand reduced some soil properties conducive to plant growth (e.g. cation exchange capacity), yet plant performance was not significantly lower than in soil-only plots. When combined with a fertilizer, plant performance significantly increased over non-amended topsoils. Trace element concentrations in supplemented soils were low and should not adversely affect plants or the local environment. Plant performance of blue wildrye (mixed genotype variety) was shown to be higher than all other species examined and is suggested as the best candidate for the revegetation at Huckleberry Mine.

Geometric Modular Action, Wedge Duality and Lorentz Covariance are Equivalent for Generalized Free Fields

description: The Tomita-Takesaki modular groups and conjugations for the observable algebras of space-like wedges and the vacuum state are computed for translationally covariant, but possibly not Lorentz covariant, generalized free quantum fields in arbitrary space-time dimension d. It is shown that for $d\geq 4$ the condition of geometric modular action (CGMA) of Buchholz, Dreyer, Florig and Summers \cite{BDFS}, Lorentz covariance and wedge duality are all equivalent in these models. The same holds for d=3 if there is a mass gap. For massless fields in d=3, and for d=2 and arbitrary mass, CGMA does not imply Lorentz covariance of the field itself, but only of the maximal local net generated by the field.
Planning for Innovation: An Analysis of Bus Rapid Transit and Institutional Approaches to Transportation Innovation

description: This study explores the institutional implications of Bus Rapid Transit (BRT) as a technological innovation. As an alternative to rail-based mass transit systems, bus rapid transit has emerged as an adaptable and cost-effective means of providing high quality urban mobility. Since its development in Curitiba, Brazil in 1974, over 140 cities have since gone on to implement BRT. While the technological features of BRT are well understood, the role of various stakeholders, institutions, and planning processes is often underemphasized, despite holding the key to successful implementation. By focusing on the experience of Bogota, Colombia and Johannesburg, South Africa in incorporating existing transportation service providers into new BRT systems, this study explores the institutional implications of innovation and the embedding of new planning practices into local contexts. By addressing these questions, I hope to shed light on the processes of innovation and diffusion, so that planners, policy makers, and other stakeholders can be better informed when implementing new technologies such as bus rapid transit.

description: Differentiable programming is a fresh programming paradigm which composes parameterized algorithmic components and trains them using automatic differentiation (AD). The concept emerges from deep learning but is not only limited to training neural networks. We present theory and practice of programming tensor network algorithms in a fully differentiable way. By formulating the tensor network algorithm as a computation graph, one can compute higher order derivatives of the program accurately and efficiently using AD. We present essential techniques to differentiate through the tensor networks contractions, including stable AD for tensor decomposition and efficient backpropagation through fixed point iterations. As a demonstration, we compute the specific heat of the Ising model directly by taking the second order derivative of the free energy obtained in the tensor renormalization group calculation. Next, we perform gradient based variational optimization of infinite projected entangled pair states for quantum antiferromagnetic Heisenberg model and obtain start-of-the-art variational energy and magnetization with moderate efforts. Differentiable programming removes laborious human efforts in deriving and implementing analytical gradients for tensor network programs, which opens the door to more innovations in tensor network algorithms and applications.

description: We study a bound system of N identical bosons interacting by model pair potentials of the form V(r) = A sgn(p)r^p + B/r^2, A > 0, B >= 0. By using a variational trial function and the `equivalent 2-body method', we find explicit upper and lower bound formulas for the N-particle ground-state energy in arbitrary spatial dimensions d > 2 for the two cases p = 2 and p = -1. It is demonstrated that the upper bound can be systematically improved with the aid of a special large-N limit in collective field theory.
Floquet states and persistent currents transitions in a mesoscopic ring

description: We consider the effect of an oscillating potential on the single-particle spectrum and the time-averaged persistent current of a one-dimensional phase-coherent mesoscopic ring with a magnetic flux. We show that in a ring with an even number of spinless electrons the oscillating potential has a strong effect on the persistent current when the excited side bands are close to the eigen levels of a pure ring. Resonant enhancement of side bands of the Floquet state generates a sign change of the persistent current.

description: I set out to prove that deinstitutionalization caused a grand dis-service to the mentally ill, leaving many individuals homeless and without proper care. It was my intention to prove that while they were improperly resourced, institutions served a purpose in society. Public perception and politics played large roles in the inefficiencies of resourcing institutions and subsequent housing and housing programs for the mentally ill and mentally ill homeless. The nexus between mental illness and homelessness has been proven time and again in scholarly literature, however the nexus between deinstitutionalization and an increase in homelessness is tenuous. Though it is clear that deinstitutionalization highlights a distinct gap in service provision and housing which led to homelessness. The literature documents difficulties in housing mentally ill persons throughout the decades and also the significance in recent spikes in mentally ill homeless. Through the collection of oral histories, I have deduced that an area in which future planners should do more research is on the effects of supportive housing programs on the communities in which they are developed. Perhaps by highlighting the ways in which engaging in mental illness services and resources as a community, we may find a way to reduce or even remove the stigma which has plagued individuals with mental illness for centuries.

description: We present a theory for describing the inner structure of the electron bunch in the bubble regime starting from a random distribution of electrons inside the bubble and subsequently minimizing the system's energy. Consequently, we find a filament-like structure in the direction of propagation that is surrounded by various shells consisting of further electrons. If we specify a 2D initial structure, we observe a hexagonal structure for a high number of particles, corresponding to the close-packing of spheres in two dimensions. The two-dimensional structures are in agreement with the equilibrium slice model (ESM).

description: Scale-invariant actions in arbitrary dimensions are investigated in curved space to clarify the relation between scale-, Weyl- and conformal invariance on the classical level. The global Weyl-group is gauged. Then the class of actions is determined for which Weyl-gauging may be replaced by a suitable coupling to the curvature (Ricci gauging). It is shown that this class is exactly the class of actions which are conformally invariant in flat space. The procedure yields a simple algebraic criterion for conformal invariance and produces the improved energy-momentum tensor in conformally invariant theories in a systematic way. It also provides a simple and fundamental connection between Weyl-anomalies and central extensions in two dimensions. In particular, the subset of scale-invariant Lagrangians for fields of arbitrary spin, in any dimension, which are conformally invariant is given. An example of a quadratic action for which scale-invariance does not imply conformal invariance is constructed.
