description: The standard implementation of the conjugate gradient algorithm suffers from communication bottlenecks on parallel architectures, due primarily to the two global reductions required every iteration. In this paper, we study conjugate gradient variants which decrease the runtime per iteration by overlapping global synchronizations, and in the case of pipelined variants, matrix-vector products. Through the use of a predict-and-recompute scheme, whereby recursively-updated quantities are first used as a predictor for their true values and then recomputed exactly at a later point in the iteration, these variants are observed to have convergence behavior nearly as good as the standard conjugate gradient implementation on a variety of test problems. We provide a rounding error analysis which provides insight into this observation. It is also verified experimentally that the variants studied do indeed reduce the runtime per iteration in practice and that they scale similarly to previously-studied communication-hiding variants. Finally, because these variants achieve good convergence without the use of any additional input parameters, they have the potential to be used in place of the standard conjugate gradient implementation in a range of applications.

description: A research program supported by Westmin Resources and the Mineral Development Agreement (MDA), has evaluated the use of cementitious dry surface covers in the prevention of water and oxygen infiltration into acid waste rock piles. This paper presents the results of a field trial of a dry cover over a large test area on a waste rock pile at the Westmin Myra Falls site. The field trial was supported by Westmin Resources and CANMET under the Mine Environment Neutral Drainage (MEND) program. The objectives of this study were to apply the cementitious cover in the most cost effective manner and to evaluate the material properties and the long term efficacy of the cover system. Approximately 3500 square metres of area was covered using the shotcrete process. A robotic arm mounted onto a vehicle was used to apply the shotcrete onto the rock slope. The cementitious material used in the project incorporated high volumes of fly ash (a waste product) to reduce the material cost. The shotcrete mix also included the use of polypropylene fibres to control cracks. The test area was instrumented with infiltration boxes and survey markers to monitor seepage through the shotcrete and settlement in the rock slope. The performance of this test area will be monitored over the subsequent years to evaluate the long term durability of this cover when subjected to field conditions.

description: In this paper we develop a functorial language of probabilistic morphisms and apply it to some basic problems in Bayesian nonparametrics. First we extend and unify the Kleisli category of probabilistic morphisms proposed by Lawvere and Giry with the category of statistical models proposed by Chentsov and Morse-Sacksteder. Then we introduce the notion of a Bayesian statistical model that formalizes the notion of a parameter space with a given prior distribution in Bayesian statistics. {We revisit the existence of a posterior distribution, using probabilistic morphisms}. In particular, we give an explicit formula for posterior distributions of the Bayesian statistical model, assuming that the underlying parameter space is a Souslin space and the sample space is a subset in a complete connected finite dimensional Riemannian manifold. Then we give a new proof of the existence of Dirichlet measures over any measurable space using a functorial property of the Dirichlet map constructed by Sethuraman.

description: Recent calculations have shown that the linear proportionality between black hole entropy and area can be explained by performing a density matrix calculation for a massless free field theory. By applying the same formalism to an empirical fluid ``field theory,'' entropic quantities such as surface tension can be calculated in a novel fashion. Good agreement with experiment is obtained for a number of liquids. This approach may lead to a practical new technique for the evaluation of thermodynamic quantities important entropic components. Implications for the protein folding problem are discussed.

Subjects: International Relations/Trade

description: This paper relaxes the assumption of perfect and costless policy enforcement implicit in traditional analysis of output and export subsidies and introduces enforcement costs and cheating into the economic analysis of these policy instruments. Analytical results show that compliance with policy rules is not the natural outcome of self-interest and complete deterrence of cheating is not economically efficient. The introduction of enforcement costs and cheating changes the welfare effects of the policy mechanisms, their efficiency in redistributing income to producers, and their normative ranking in terms of transfer efficiency.

description: Bluegrass as it is played in the United States today is not simply a resistant category of country music, but performs a particular and emergent view of past/present relations. More than a "micromusic" mediating between "supercultures" and "subcultures" (in Mark Slobin's terms 1993), in fact bluegrass's complex history resists simple top down or bottom up perspectives, articulating a distinct space of authenticity. Active `genre tending' in a jam setting poetically articulates emergent social relations, in a specific spatiotemporal frame, at New York City's The Baggot Inn jam scene, a site of bluegrass performance at which the genre is employed creatively as a way of socializing and articulating contemporary presence. Learning a genre on an individual level is an actively embodied linking of technique and feeling, and differing listening experiences may lead to differing ideas of what a musical text represents. Expressive skill, executed through embodied musical gestures derived from specific pieces of music, may embed personal biography with social history and experience. Successful coperformance of a genre (bluegrass, in this case) requires a dynamic performative flexibility. This flexibility in turn can permanently affect both player and context, though different players may have to work to agree or disagree. These live, face to face interactions which depend on local specifics, maintain the coherence of the wider musical genre that facilitates those very actions themselves.

description: We look for spectral type differential equations satisfied by the generalized Jacobi polynomials which are orthogonal on the interval [-1,1] with respect to a weight function consisting of the classical Jacobi weight function together with point masses at the endpoints of the interval of orthogonality. In order to find explicit formulas for the coefficients of these differential equations we have to solve systems of equations involving derivatives of the classical Jacobi polynomials. These systems of equations have a unique solution which can be given explicitly in terms of Jacobi polynomials. This is a consequence of the Jacobi inversion formula which is proved in this paper.

description: Recently, brightness variations occurring on twice the accretion disk precession period in the old nova and permanent superhump system V603 Aql have been observed by Bruch & Cook (2018). In an attempt to detect a similar effect in other cataclysmic variables reported to contain permanent superhumps the novalike variable UU Aqr was observed during 11 nights in September 2018. While no traces of superhumps were seen in the data, rendering the quest for variations related to the disk precession period obsolete, the system exhibits regular variations with a period of ~4 days.

description: This dissertation examined the changes of Geometry Education in New York State in connection with the differences in the New York State Mathematics Standards (1999, 2005, 2011).  As a result of this analysis, a theoretical framework was created to support teachers in making the shift from teaching towards the 2005 learning standards to teaching towards the goals of the Common Core Standards (2011).  Once created, the theoretical framework served as the basis of the development of a collection of problems on various topics in geometry used by teachers in their geometry classrooms.  This document can be found in the Appendix of this dissertation.
      	As seen in the past, curriculum, standards, and assessment are all intertwined and reflect one another.  In order to bridge the gaps and explore relationships between these components, this research compares the various New York State Mathematics Standards to determine differences in topical coverage as well as an analysis of the New York State Geometry Regents examinations under the 2005 standards and Common Core Standards.  Additionally, the research builds on these results and also analyzes select New York State Regents Examination questions in specific topics.  This study used the information gathered to create a collection of problems based on certain principles to support teachers in adequate preparation of students for the Common Core Geometry Course.  Teachers found the principles provided to be very useful in creating their own problems for additional topics, and found the collection of problems to be very helpful in the teaching and learning of geometry to their students.

description: In a recent Letter [Phys. Rev. Lett. 79, 889 (1997) and cond-mat/9702054] we have demonstrated that the avalanches in the Bak-Sneppen model display aging behavior similar to glassy systems. Numerical results for temporal correlations show a broad distribution with two distinct regimes separated by a time scale which is related to the age of the avalanche. This dynamical breaking of time-translational invariance results in a new critical exponent, $r$. Here we present results for $r$ from extensive numerical simulations of self-organized critical models in $d=1$ and 2. We find $r_{d=1}=0.45\pm 0.05$ and $r_{d=2}=0.23\pm 0.05$ for the Bak-Sneppen model, and our results suggest $r=1/4$ for the analytically tractable multi-trade model in both dimensions.

The Emergence of Functional Consciousness in the Internet: A Quantitative Model
Creators: name: Monroe, Scott
Publisher: name: Zenodo
Year: 2025

description: In Integrated Information Technology, when a system integrates information in a highly complex manner, a form of consciousness will arise. IIT states that the more interconnected and differentiated the information in a system is, the higher the probability of consciousness manifesting provided it reaches a certain level of integration. We quantify this as “Phi”.

In theory, if we had a sprawling network with enough nodes and feedback loops, it could approach this threshold, however there is no evidence yet that scale alone is enough. That is where my model was developed from. The internet is the largest, most interconnected and diverse network of shared information on the planet, so therefore it makes the perfect study subject, to formulate a mathematical model from.

description: Figure S1. Effect of large concentration of carbon in area or mass on SMA regression. We assumed that the mass in a sample consists of C/0.45 + Z, where 0.45 is the concentration of C in biomass, and Z is material other than organics (minerals, water) on an area basis. The left figure assumes Z = 0, as it may occur in vegetation, where carbon and a nutrient (N) scale allometrically with a SMA slope of 0.8. The slope becomes zero if normalized on a per mass basis (note, we normalized the values so that they are identical at log(N) = 0). We then accounted for different amounts of non-organics (varying Z, bottom). Sufficient high Z lead to convergence of SMA slopes, but differences occur with decreasing Z, and become substantial for peat soils as analyzed in this study. (DOCX 60 kb)

description: We construct noncommutative `Riemannian manifold' structures on dual quasitriangular Hopf algebras such as $C_q[SU_2]$ with its standard bicovariant differential calculus, using the quantum frame bundle formalism introduced previously. The metric is provided by the braided-Killing form on the braided-Lie algebra on the tangent space and the $n$-bein by the Maurer-Cartan form. We also apply the theory to finite sets and in particular to finite group function algebras $C[G]$ with differential calculi and Killing forms determined by a conjugacy class. The case of the permutation group $C[S_3]$ is worked out in full detail and a unique torsion free and cotorsion free or `Levi-Civita' connection is obtained with noncommutative Ricci curvature essentially proportional to the metric (an Einstein space). We also construct Dirac operators in the metric background, including on finite groups such as $S_3$. In the process we clarify the construction of connections from gauge fields with nonuniversal calculi on quantum principal bundles of tensor product form.

Impossible Heroes: Heroism and Political Experience in Early Modern England
Creators: Lowrance, Bryan John
Publisher: name: Columbia University
Year: 2012
Subjects: Literature

description: During the late sixteenth and seventeenth centuries the English commonwealth was caught between competing concepts of the political. England's political culture had traditionally combined monarchy with local autonomy, office-holding, and a republican ethos that understood politics in terms of dynamic individual action and potentiality. In the Renaissance, however, this plural and personalized political paradigm was increasingly at odds with the centralizing tendencies of the Tudor-Stuart monarchs. The tensions that resulted led to both real-world tumults (the Northern Rebellion of 1569, Essex Revolt of 1601, the Civil Wars of 1642-51) and more subtle expressions of political pessimism and anxiety across England's literary and cultural discourses. But this same period also saw a sudden surge of interest in heroism. In a moment when the political impotence of individual action was widely felt, many of England's most prominent writers turned to heroic fictions that imagined personal potential triumphing over constituted political authority. Impossible Heroes argues that we can understand this paradox only if we recognize that heroism functioned in early modern England as a complex political fantasy, one that tried to suture symbolically the widening rift between individual action and the increasing abstraction and alienation of state power. This political function is apparent across early modern English literature, from Spenser's Faerie Queene to Davenant's Gondibert and Dryden's heroic tragedies. But while these writers (and others) use heroism to reconcile the individual to the political totality of the state, Impossible Heroes focuses on four writers--Philip Sidney, Christopher Marlowe, George Chapman, and William Shakespeare--who deploy heroism to craft a different political fantasy. All these writers worked during the final years of Elizabeth's reign and the early years of James I's, anxious decades when royal authoritarianism went hand-in-hand with a widespread sense of political alienation. But rather than using heroism to alleviate this alienation, they emphasized the growing incompatibility between a dynamic, action-oriented experience of political life and institutional situations that conspired (as the Earl of Essex put it) to "suppress all noble, virtuous, and heroical spirits."  Sidney, Marlowe, Chapman and Shakespeare portray heroism as impossible in practice. But out of this practical impossibility, their work posits heroism's potential as a utopian poetic and political fantasy of individual action.

description: Mapping the intergalactic medium (IGM) in Lyman-$α$ emission would yield unprecedented tomographic information on the large-scale distribution of baryons and potentially provide new constraints on the UV background and various feedback processes relevant to galaxy formation. Here, we use a cosmological hydrodynamical simulation to examine the Lyman-$α$ emission of the IGM due to collisional excitations and recombinations in the presence of a UV background. We focus on gas in large-scale-structure filaments in which Lyman-$α$ radiative transfer effects are expected to be moderate. At low density the emission is primarily due to fluorescent re-emission of the ionising UV background due to recombinations, while collisional excitations dominate at higher densities. We discuss prospects of current and future observational facilities to detect this emission and find that the emission of filaments of the cosmic web will typically be dominated by the halos and galaxies embedded in them, rather than by the lower density filament gas outside halos. Detecting filament gas directly would require a very long exposure with a MUSE-like instrument on the ELT. Our most robust predictions that act as lower limits indicate this would be slightly less challenging at lower redshifts ($z \lesssim 4$). We also find that there is a large amount of variance between fields in our mock observations. High-redshift protoclusters appear to be the most promising environment to observe the filamentary IGM in Lyman-$α$ emission.

On the Geometry of Graeffe Iteration

Publisher: name: arXiv
Year: 1999
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: A new version of the Graeffe algorithm for finding all the roots of univariate complex polynomials is proposed. It is obtained from the classical algorithm by a process analogous to renormalization of dynamical systems. This iteration is called Renormalized Graeffe Iteration. It is globally convergent, with probability 1. All quantities involved in the computation are bounded, once the initial polynomial is given (with probability 1). This implies remarkable stability properties for the new algorithm, thus overcoming known limitations of the classical Graeffe algorithm. If we start with a degree-$d$ polynomial, each renormalized Graeffe iteration costs $O(d^2)$ arithmetic operations, with memory $O(d)$. A probabilistic global complexity bound is given. The case of univariate real polynomials is briefly discussed. A numerical implementation of the algorithm presented herein allowed us to solve random polynomials of degree up to 1000.

title: Understanding implementation: the Maryhill Corridor Project
Creators: name: Moore, Hugh A.M.
Publisher: name: University of Glasgow
Year: 1985

description: The Study of Implementation has been one of the most obscure aspects of planning, partly because of the lack of documentation and analysis of the processes which it is characterised by and partly because of the complexity and mercurial nature of such processes in practise. This reseach has centred around the examination of implementation in the planning process by focusing attention on a particular place through a particular period of time. The place is Maryhill and the time period is the duration of the Maryhill Corridor Project (1978-84). The thesis is structured on an analysis of alternative views of implementation within a theoretical context where the conventional wisdom of the separation of policy and planning from its implementation is contrasted with an "action-oriented" approach. The issues which the discussion raises provides the backcloth against which the in-depth empirical research of the case study material is presented. This is followed by an evaluation of the factors and processes which have been seen to be significant in influencing implementation. The analysis is fundamentally based on a critique of the rational-comprehensive conceptualisation of the planning process. Finally, the thesis returns to an assessment of how the theoretical understanding of the planning process relates to the processes which have been identified in reality. It is at the interface of theory and practise to which this research is directed, where the study of implementation becomes most significant and where the coming together of different actors and agencies plays a central part.

NOTE
Nous n’avons pas pu examiner le matériel type de Bulbophyllum mayombeense Garay. Cependant la description et l’illustration fournies par Garay (1999), l’image numérisée de l’holotype déposé à Vienne (http://herbarium.univie.ac.at/ database/detail.php?ID=34638) ainsi que les photos de détail des inflorescences, de la fleur, du labelle et des stélidies du matériel vivant cultivé à Vienne et à partir duquel fut prélevé l’holotype (http://www.univie.ac.at/HBV/categories.php?cat_id=270&l=french) montrent très distinctement que ce taxon n’est pas différent de B. schinzianum Kraenzl. var. schinzianum. Garay n’a certainement pas vu le type de ce dernier taxon dont la description faite par Vermeulen (1987) recoupe en tout point celle de B. mayombeense. Dans sa description, Garay (1999) rapproche plutôt son B. mayombeense de B. saltatorium var. albociliatum et les distingue par la forme des pétales (linéaire, non-arquée ou falciforme) et de la colonne qui présente des stélidies dirigées vers le haut, non-falciformes.
Ces observations nous amènent à placer Bulbophyllum mayombeense en synonymie de B. schinzianum var. schinzianum, nouvellement signalé ici pour la République du Congo.

description: We both show experimentally and numerically that the time scales separation introduced by long range activation can induce oscillations and excitability in nonequilibrium reaction-diffusion systems that would otherwise only exhibit bistability. Namely, we show that the Chlorite-Tetrathionate reaction, where autocatalytic species diffuses faster than the substrates, the spatial bistability domain in the nonequilibrium phase diagram is extended with oscillatory and excitability domains. A simple model and a more realistic model qualitatively account for the observed behavior. The latter model provides quantitative agreement with the experiments.

description: We calculate the decay width of the photon splitting into three photons in a model of quantum electrodynamics with broken Lorentz invariance. We show that this process can lead to a cut-off in the very-high-energy part of a photon spectra of astrophysical sources. We obtain the 95\% CL bound on the Lorentz violating mass scale for photons from the analysis of the very-high-energy part of the Crab Nebula spectrum, obtained by HEGRA. This bound improves previous constraints by more than an order of magnitude.

Qualitative environmental risk assessment applied to the proposed Windy Craggy Project
Creators: name: Pelletier, Clem
name: Dushnisky, Kelvin
Publisher: name: The University of British Columbia
Year: 2009

description: The concept of risk incorporates two predictive aspects: how frequently might an event be expected to occur and what might be the attendant consequences if it should? Environmental Risk Assessment (ERA) is gaining increasing acceptance as a valuable and systematic method for addressing these questions, as regards matters environmental, and has evolved in response to several compelling issues. Among these are the need to respond to the stringent regulatory framework governing project development and to distill, from the multitude of concerns associated with mine development, the key environmental risks requiring particular consideration. It is the latter function of ERA that is viewed as especially beneficial by both mining companies and government regulators alike. By identifying the elements of project design that pose key risks, due to various uncertainties, recommendations can be made to manage and reduce them as the project is developed, operated and, ultimately, abandoned. This paper outlines the results of a Qualitative Risk Assessment completed on the Windy Craggy Project proposed for development in northwestern British Columbia. Special attention is afforded to post-closure reclamation considerations.
Quantum Stability of (2+1)-Spacetimes with Non-Trivial Topology

description: Quantum fields are investigated in the (2+1)-open-universes with non-trivial topologies by the method of images. The universes are locally de Sitter spacetime and anti-de Sitter spacetime. In the present article we study spacetimes whose spatial topologies are a torus with a cusp and a sphere with three cusps as a step toward the more general case. A quantum energy momentum tensor is obtained by the point stripping method. Though the cusps are no singularities, the latter cusps cause the divergence of the quantum field. This suggests that only the latter cusps are quantum mechanically unstable. Of course at the singularity of the background spacetime the quantum field diverges. Also the possibility of the divergence of topological effect by a negative spatial curvature is discussed. Since the volume of the negatively curved space is larger than that of the flat space, one see so many images of a single source by the non-trivial topology. It is confirmed that this divergence does not appear in our models of topologies. The results will be applicable to the case of three dimensional multi black hole\cite{BR}.

On the distribution of $αp$ modulo one in imaginary quadratic number fields with class number one

description: We investigate the distribution of $αp$ modulo one in imaginary quadratic number fields $\mathbb{K}\subset\mathbb{C}$ with class number one, where $p$ is restricted to prime elements in the ring of integers $\mathcal{O} = \mathbb{Z}[ω]$ of $\mathbb{K}$. In analogy to classical work due to R. C. Vaughan, we obtain that the inequality $\lVertαp\rVert_ω< \mathrm{N}(p)^{-1/8+ε}$ is satisfied for infinitely many $p$, where $\lVert\varrho\rVert_ω$ measures the distance of $\varrho\in\mathbb{C}$ to $\mathscr{O}$ and $\mathrm{N}(p)$ denotes the norm of $p$. The proof is based on Harman's sieve method and employs number field analogues of classical ideas due to Vinogradov. Moreover, we introduce a smoothing which allows us to make conveniently use of the Poisson summation formula.

description: Spherical Harmonics, $Y_\ell^m(θ,ϕ)$, are derived and presented (in a Table) for half-odd-integer values of $\ell$ and $m$. These functions are eigenfunctions of $L^2$ and $L_z$ written as differential operators in the spherical-polar angles, $θ$ and $ϕ$. The Fermion Spherical Harmonics are a new, scalar and angular-coordinate-dependent representation of fermion spin angular momentum. They have $4π$ symmetry in the angle $ϕ$, and hence are not single-valued functions on the Euclidean unit sphere; they are double-valued functions on the sphere, or alternatively are interpreted as having a double-sphere as their domain.

description: We show that the quantum relaxation process in a classically chaotic open dynamical system is characterized by a quantum relaxation time scale t_q. This scale is much shorter than the Heisenberg time and much larger than the Ehrenfest time: t_q ~ g^alpha where g is the conductance of the system and the exponent alpha is close to 1/2. As a result, quantum and classical decay probabilities remain close up to values P ~ exp(-sqrt(g)) similarly to the case of open disordered systems.
description: revtex, 5 pages, 4 figures discussion of the relations between time scale t_q and weak localization correction and between dynamical and disordered systems is added
