Topological Lattice Gravity Using Self-Dual Variables

Publisher: name: arXiv
Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Topological gravity is the reduction of general relativity to flat space-times. A lattice model describing topological gravity is developed starting from a Hamiltonian lattice version of $B\w F$ theory. The extra symmetries not present in gravity that kill the local degrees of freedom in $B\wedge F$ theory are removed. The remaining symmetries preserve the geometrical character of the lattice. Using self-dual variables, the conditions that guarantee the geometricity of the lattice become reality conditions. The local part of the remaining symmetry generators, that respect the geometricity-reality conditions, has the form of Ashtekar's constraints for GR. Only after constraining the initial data to flat lattices and considering the non-local (plus local) part of the constraints does the algebra of the symmetry generators close. A strategy to extend the model for non-flat connections and quantization are discussed.

description: Exact cosmological solutions for effective actions in D dimensions inspired by the tree-level superstring action are studied. For a certain range of free parameters existing in the model, nonsingular bouncing solutions are found. Among them, of particular interest can be open hyperbolic models, in which, without any fine tuning, the internal scale factor and the dilaton field (connected with string coupling in string theories) tend to constant values at late times. A cosmological singularity is avoided due to nonminimal dilaton-gravity coupling and, for D > 11, due to pure imaginary nature of the dilaton, which conforms to currently discussed unification models. The existence of such and similar solutions supports the opinion that the Universe had never undergone a stage driven by full-scale quantum gravity.

Landscape design : a new planning and assessment framework for mine reclamation
Creators: name: McKenna, Gord
name: Ducharme, Janelle
name: Keys, Marie
Publisher: name: The University of British Columbia
Year: 2009

description: Traditional mine reclamation has focused on greening up disturbed areas. As a mining operation finishes with the land, it is turned over to the reclamation department, regraded, top soiled and planted. Eventually this land is turned back to the original owner. To date, this approach has had considerable success except that, in the end, lands are seldom returned to the original owner due to uncertainties in future landscape performance. As mine sites become larger and expectations of regulatory agencies, other stakeholders and the mining companies become greater, greening up small areas in a patch-work quilt-like fashion can result in a landscape that fails to meet expectations. Recognizing that a broader approach with a new framework is required, Syncrude has been developing a process called landscape design to meet this challenge. Landscape design begins with defining spécifie objectives for landscape performance, with a focus on providing acceptable long-term performance for specific end land uses. Objectives can be grouped in categories such as geotechnical stability, drainage and topography, groundwater, vegetation, soil, fish and wildlife, end land use, and health and safety. Qualified specialists evaluate the objectives using performance indicators (short-term indicators of long-term performance) wherever possible. The performance objectives form a checklist for guiding reclamation and closure activities throughout a mine's life. This checklist is used to provide guidance in closure planning from the pre-feasibility studies and initial design of specific mining landforms, to detailed design of reclamation, and through the decommissioning arid reclamation certification process. Landscape design provides a simple, objective and transparent process for the design, construction and assessment of landscape performance. It also forms the basis for landscape performance monitoring and is integral to the development of a geographical information system (GIS). Syncrude has started implementing the landscape design process at its oil sands mining operations near Fort McMurray, Alberta.

Haroldiellus

description: Haroldiellus Gordon and Skelley, 2007
 Haroldiellus Gordon and Skelley 2007: 269. Type species: Aphodius sallei Harold 1863: 336, by original designation.
 Diagnosis. [Modified from Gordon and Skelley 2007, and Skelley’s website (Skelley 2008)] Body length 4.3–5.8 mm, ovate, robust, dark brown to black. Body not fimbriate. Head with three tubercles along frontal suture, lateral ones weak, most prominent in males. Clypeus lacking teeth and setal fringe. Scutellum small, pentagonal. Elytral striae deep and coarsely punctate. Protibial dorsal surface with few punctures in an indistinct longitudinal row, lost in some species. Metatibial apical spinules short and equal in length.
 Remarks. A key to genera of Aphodiini in the US is in Gordon and Skelley (2007). A key to New World genera can be found at Skelley (2008). Gordon and Skelley’s (2007) generic description was based primarily on H. sallei. Specimens of H. lansbergei and the new species were not available at that time. The protibial punctation partially used to define Haroldiellus is present only on H. sallei, not on the other species.
 The tribe Aphodiini can be divided easily by genera that possess a punctate dorsal protibial surface and those that do not. However, the vast majority of those with a punctate surface are covered with scattered, more densely spaced punctures. In H. sallei and Gordonius Skelley, the protibial punctures are few, sparse and arranged in a couple more or less longitudinal, medial rows. In the New World, the body shape of those with dense protibial punctation is more elongate and flattened, while Haroldiellus and Gordonius are robust and more rounded.

description: Most NLP and Computer Vision tasks are limited to scarcity of labelled data. In social media emotion classification and other related tasks, hashtags have been used as indicators to label data. With the rapid increase in emoji usage of social media, emojis are used as an additional feature for major social NLP tasks. However, this is less explored in case of multimedia posts on social media where posts are composed of both image and text. At the same time, w.e have seen a surge in the interest to incorporate domain knowledge to improve machine understanding of text. In this paper, we investigate whether domain knowledge for emoji can improve the accuracy of emotion classification task. We exploit the importance of different modalities from social media post for emotion classification task using state-of-the-art deep learning architectures. Our experiments demonstrate that the three modalities (text, emoji and images) encode different information to express emotion and therefore can complement each other. Our results also demonstrate that emoji sense depends on the textual context, and emoji combined with text encodes better information than considered separately. The highest accuracy of 71.98\% is achieved with a training data of 550k posts.

description: Causal inference -- the process of drawing a conclusion about the impact of an exposure on an outcome -- is foundational to biomedicine, where it is used to guide intervention. The current gold-standard approach for causal inference is randomized experimentation, such as randomized controlled trials (RCTs). Yet, randomized experiments, including RCTs, often enforce strict eligibility criteria that impede the generalizability of causal knowledge to the real world. Observational data, such as the electronic health record (EHR), is often regarded as a more representative source from which to generate causal knowledge. However, observational data is non-randomized, and therefore causal estimates from this source are susceptible to bias from confounders. This weakness complicates two central tasks of causal inference: the replication or evaluation of existing causal knowledge and the generation of new causal knowledge. In this dissertation I (i) address the feasibility of observational data to replicate existing causal knowledge and (ii) present new methods for the generation of causal knowledge with observational data, with a focus on the causal tasks of comparing an outcome between two cohorts and the estimation of attributable risks of exposures in a causal system.

Then each component manifold M_i of M-F has handle number at most one, i.e. admits a Heegaard splitting obtained by attaching a single 1-handle to one or two components of boundary M_i. This result also holds for a decomposition of M along a maximal collection of incompressible tori.

description: We study field equations for a weak anisotropic model on the tangent Lorentz bundle $TM$ of a spacetime manifold. A geometrical extension of General Relativity (GR) is considered by introducing the concept of local anisotropy, i.e. a direct dependence of geometrical quantities on observer $4-$velocity. In this approach, we consider a metric on $TM$ as the sum of an h-Riemannian metric structure and a weak anisotropic perturbation, field equations with extra terms are obtained for this model. As well, extended Raychaudhuri equations are studied in the framework of Finsler-like extensions. Canonical momentum and mass-shell equation are also generalized in relation to their GR counterparts. Quantization of the mass-shell equation leads to a generalization of the Klein-Gordon equation and dispersion relation for a scalar field. In this model the accelerated expansion of the universe can be attributed to the geometry itself. A cosmological bounce is modeled with the introduction of an anisotropic scalar field. Also, the electromagnetic field equations are directly incorporated in this framework.

description: Global industrialization generates large amount of waste which strongly affects the depositing areas andthe living creatures from the surroundings. In the same time, the construction sector meets an exponentialdevelopment process, resulting in materials and construction areas increase. Therefore, the need of newmaterials was felt worldwide. One solution that knew a rapid development, especially in this sector, was toobtain new eco-friendly materials through a mechanism called geopolymerization. True this powerfulchemical reaction between a waste, rich in aluminum and silicon, and a strong alkaline solution, a tetragonalstructure of Al-O-Si is obtained that possess properties comparable to those of Portland cement-basedconcrete. In the present paper the effect of aggregates on local fly ash based geopolymers is analyzed fromthe structure and mechanical properties point of view. According to this study, the aggregates stronglyinfluence the density, compression strength and flexural strength at any age of samples.
Parallel Controllability Methods For the Helmholtz Equation

description: The Helmholtz equation is notoriously difficult to solve with standard numerical methods, increasingly so, in fact, at higher frequencies. Controllability methods instead transform the problem back to the time-domain, where they seek the time-harmonic solution of the corresponding time-dependent wave equation. Two different approaches are considered here based either on the first or second-order formulation of the wave equation. Both are extended to general boundary-value problems governed by the Helmholtz equation and lead to robust and inherently parallel algorithms. Numerical results illustrate the accuracy, convergence and strong scalability of controllability methods for the solution of high frequency Helmholtz equations with up to a billion unknowns on massively parallel architectures.

description: In this paper, discrete analogues of Euler-Poincaré and Lie-Poisson reduction theory are developed for systems on finite dimensional Lie groups $G$ with Lagrangians $L:TG \to {\mathbb R}$ that are $G$-invariant. These discrete equations provide ``reduced'' numerical algorithms which manifestly preserve the symplectic structure. The manifold $G \times G$ is used as an approximation of $TG$, and a discrete Langragian ${\mathbb L}:G \times G \to {\mathbb R}$ is construced in such a way that the $G$-invariance property is preserved. Reduction by $G$ results in new ``variational'' principle for the reduced Lagrangian $\ell:G \to {\mathbb R}$, and provides the discrete Euler-Poincaré (DEP) equations. Reconstruction of these equations recovers the discrete Euler-Lagrange equations developed in \cite{MPS,WM} which are naturally symplectic-momentum algorithms. Furthermore, the solution of the DEP algorithm immediately leads to a discrete Lie-Poisson (DLP) algorithm. It is shown that when $G=\text{SO} (n)$, the DEP and DLP algorithms for a particular choice of the discrete Lagrangian ${\mathbb L}$ are equivalent to the Moser-Veselov scheme for the generalized rigid body. %As an application, a reduced symplectic integrator for two dimensional %hydrodynamics is constructed using the SU$(n)$ approximation to the volume %preserving diffeomorphism group of ${\mathbb T}^2$.

description: Simultaneous electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) have gained increasing popularity in studying human cognition due to their potential to map the brain dynamics with high spatial and temporal fidelity. Such detailed mapping of the brain is crucial for understanding the neural mechanisms by which humans make perceptual decisions. Despite recent advances in data acquisition and analysis of simultaneous EEG-fMRI, the lack of effective computational tools for optimal fusion of the two modalities remains a major challenge. The goal of this dissertation is to provide a recipe of machine learning methods for fusion of simultaneous EEG-fMRI data. Specifically, we investigate three types of fusion approaches and apply them to study the whole-brain spatiotemporal dynamics during a rapid object recognition task where subjects discriminate face, car, and house images under ambiguity. We first use an asymmetric fusion approach capitalizing on temporal single-trial EEG variability to identify early and late neural subsystems selective to categorical choice of faces versus nonfaces. We find that the degree of interaction in these networks accounts for a substantial fraction of our bias to see faces. Based on a computational modeling of behavioral measures, we further dissociate separate neural correlates of the face decision bias modulated by varying levels of stimulus evidence. Secondly, we develop a state-space model based symmetric fusion approach to integrate EEG and fMRI in a probabilistic generative framework. We use a variational Bayesian method to infer the network connectivity among latent neural states shared by EEG and fMRI. Finally, we use a data-driven symmetric fusion approach to compare representations of the EEG and fMRI against those of a deep convolutional neural network (CNN) in a common similarity space. We show a spatiotemporal hierarchical correspondence in visual processing stages between the human brain and the CNN. Collectively, our results show that the spatiotemporal properties of neural circuits revealed by the analysis of simultaneous EEG-fMRI data can reflect the choice behavior of subjects during rapid perceptual decision making.

description: Excavations at Norton in Bishopstone, East Sussex, revealed a pit complex, a working hollow, a grave, a stove filled with burnt stones, a midden and a horizontal terrace of Middle Iron Age date. The evidence suggests, in addition, that a non post-built house may have been located within the area of the excavation. Traces of Late Iron Age activity were also found. Among the finds made were two chronologically sequential groups of saucepan pottery, a potin coin (from a Middle Iron Age context), a sherd of Campanian amphora, and an assemblage of non-local stone. The understanding of Iron Age Norton that these discoveries make possible clarifies the county's relationship to the period outside Sussex, and to other periods within it.

These solutions were found using the connection between Yang-Mills theory and general relativity. Taking known solutions of the Yang-Mills equations (e.g. the topological BPS monopole solutions) it is possible to construct exact solutions to the general relativistic field equations. Although the general relativistic solutions were found starting from known solutions of Yang-Mills theory they have different physical characteristics.

Automatic detection of tidal disruption events and other long duration transients in XMM-Newton data

Publisher: name: arXiv
Year: 2019
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: XMM-Newton's large field of view and excellent sensitivity have resulted in hundreds of thousands of serendipitous X-ray detections. Whilst their spectra have been widely exploited, their variable nature has been little studied. Part of this is due to the way XMM-Newton currently operates, where observations generally have a 12 month proprietary period. It is often too late to follow-up a serendipitous transient a year after detection. New robust software could be introduced into the pipeline to automatically identify bright transients that are not the target of the observation. Statistically, hundreds of tidal disruption events (TDEs) have been detected serendipitously by XMM-Newton. With prior consent from the PI of the observation, an automatic alert to a new transient could be set up, allowing it to be followed-up within weeks, ideal for TDEs that are bright for about a year. Over the next decade, hundreds more TDEs should be detected. Following-up the brightest in quasi-real time would allow constraints to be made on the black hole mass, spin and accretion regime and identify intermediate-mass black holes that are expected to be hidden in faint, low-mass galaxies. This article discusses the advantages that such changes would have on the follow-up of transients and TDEs.

description: Exact solutions of classical gauge theories in even-dimensional (D=2n) spacetimes are discussed. Common and specific properties of these solutions are analyzed for the particular dimensions D=2, D=4, and D=6. A consistent formulation of classical gauge field theories with pointlike charged or colored particles is proposed for D=6. The particle Lagrangian must then depend on the acceleration. The self-interaction of a point particle is considered for D=2 and D=6. In D=2, radiation is absent and all processes are reversible. In D=6, the expression for the radiation rate and the equation of motion of a self-interacting particle are derived; from which follows that the Zitterbewegung always leads to radiation. It is shown that non-Abelian solutions are absent for any D not equal to 4; only Coulomb-like solutions, which correspond to the Abelian limit of the D-dimensional Yang--Mills--Wong theory, are admitted.

Cariboo Reclamation Project and sediment control during the construction phase of a major mine
Creators: name: McBride, Brian
Publisher: name: The University of British Columbia
Year: 2009

description: This presentation will briefly discuss the Cariboo Reclamation Project and the effectiveness of various erosion control structures implemented during the construction phase of the Kemess South Project. During the 1999 field season the Ministry of Energy and Mines implemented the Cariboo Reclamation Project aimed at cleaning up and reclaiming abandoned placer leases in the Quesnel to Barkerville area. Revenue collected from the seizure of the bonds on the properties was used as the basis for the funding of the project. The order of priority for the Cariboo Reclamation Project was to: 1) ensure public health and safety, 2) ensure there was no environmental risk, 3) remove abandoned equipment and debris, 4) recontour disturbed areas and deactivate roads, 5) revegetate disturbed areas. The second part of this paper will discuss control of sediment during the construction phase of the Kemess South Project.

description: There has been proposed a new method of the constructing of the basic functions for spaces of tensor representations of the Lie groups with the help of the generalized Casimir operator. In the definition of the operator there were used the Lie derivatives instead of the corresponding infenitisemal operators. When introducing the generalized Casimir operator we use the metric for which a group being considered will be isometry that follows from the invariance condition for the generalized Casimir operator. This allows us to formulate the eigenvalue and eigenfunction problems correctly. The invariant projection operators have been constructed in order to separate irreducible components. The cases of the Bianchi type G^3 IX and G^3 II groups are considered as examples.

description: The control of thermal expansion represents a challenge in materials design. This work shows that the length of the lattice parameter is a key element for controlling thermal expansion. By varying the lattice parameter through external pressure, chemical or other methods, the single-well potential energy of the polyhedra rotations (or of the atomic transverse vibrations) responsible for negative thermal expansion (NTE), can be turned into a quartic anharmonic potential or into a double-well potential, thus enhancing or suppressing the NTE, respectively. This result applied to framework materials should be taken into account to overcome the challenge of controlling thermal expansion. This research reveals that the thermal expansion of framework-type materials can be tuned by acting on the length of the lattice parameter.

description: Bloom Filter is a probabilistic membership data structure and it is excessively used data structure for membership query. Bloom Filter becomes the predominant data structure in approximate membership filtering. Bloom Filter extremely enhances the query response time, and the response time is very fast. Bloom filter (BF) is used to detect whether an element belongs to a given set or not. The Bloom Filter returns True Positive (TP), False Positive (FP), or True Negative (TN). The Bloom Filter is widely adapted in numerous areas to enhance the performance of a system. In this paper, we present a) in-depth insight on the Bloom Filter,and b) the prominent variants of the Bloom Filters.

 Diagnosis. Pharaxonotha can be distinguished from other members of the Pharaxonothinae by the following combination of characters: antennal club of 3 antennomeres; eyes large, encroaching upon gular area; submentalgular suture apparently lacking; stridulatory files at base of head separated by distance approximately equal to width of scutellar shield; anterior pronotal margin lacking or with very fine marginal line; lateral pronotal carina narrow, same thickness along entire length; elytra with basal bead; internal abdominal calli absent; male genitalia straight, not twisted, median lobe and tegmen rotated 180 degrees when retracted into the abdomen [see Fig. 10G and Tang et al. 2020 for examples; while it is common in the Cucujoidea for the male genitalia to be rotated 90 degrees while retracted into the abdomen (McHugh et al. 1997), 180 degrees is unusual]; median lobe cylindrical; flagellum long hair-like; tegmen flattened or not flattened, basal piece broadened and ring-like to hold coiled flagellum. Known distribution includes the Caribbean Basin from Florida and Bahamas to Greater Antillean islands of the Cayman Islands, Cuba, Jamaica, Hispaniola and Puerto Rico; mainland from southern US and Mexico to South America as far south as Bolivia.

description: Dispersions of rodlike colloidal particles exhibit a plethora of liquid crystalline states, including nematic, smectic A, smectic B, and columnar phases. This phase behavior can be explained by presuming the predominance of hard-core volume exclusion between the particles. We show here how the self-organization of rodlike colloids can be controlled by introducing a weak and highly localized directional attractive interaction between one of the ends of the particles. This has been performed by functionalizing the tips of filamentous viruses by means of regioselectively grafting fluorescent dyes onto them, resulting in a hydrophobic patch whose attraction can be tuned by varying the number of bound dye molecules. We show, in agreement with our computer simulations, that increasing the single tip attraction stabilizes the smectic phase at the expense of the nematic phase, leaving all other liquid crystalline phases invariant. For a sufficiently strong tip attraction, the nematic state may be suppressed completely to get a direct isotropic liquid-to-smectic phase transition. Our findings provide insights into the rational design of building blocks for functional structures formed at low densities.

description: It is shown, for the self-consistent system of scalar, electro-magnetic and gravitational fields in general relativity, that the equations of motion admit a special kind of solutions with spherical or cylindrical symmetry. For these solutions, the physical fields vanish and the space-time is flat outside of the critical sphere or cylinder. Therefore, the mass and the electric charge of these configurations are zero. The principal difference between droplet-like solutions with spherical symmetry and those with cylindrical one has been established. In the first case there exists a possibility of continuous transformation of droplet-like configuration into the solitonian one, when for the second case there is no such a possibility.

description: The observed correlation between the EMC effect and the contribution of short-range correlations (SRCs) in nuclei suggests that the modification of the quark distributions of bound protons and neutrons might occur within SRCs. This raises the possibility that the EMC effect may have an isospin dependence arising from the np dominance of SRCs. We discuss previous attempts to test this possibility and perform a new analysis of existing data. We find no experimental support for the observation of an isospin dependence of the EMC effect.

description: The Higher Education Enrolment Decision Support System (HEEDS) of Cagayan State University has been provided as a toolto support registration, assessment, and grade monitoring of students as well as provision ofknowledge to support top-level management decision making. Students, teachers, and administrative support acknowledges the potential of the HEEDS to faster turnaround,efficient utilization of resources, faster delivery of basic transactions, as well timeliness and security of student’s important profile and information. Guided with the ISO 9126 software quality characteristics, the case study employed basic questionnaire, key information interview, analysis of the processes, and documentary review of the operations to obtain necessary data needed to evaluate the current system case. Findings revealed both positive and negative views on the processes, usability and acceptability. Notable strengths and weakness were defined as well as possible opportunities and threats. Information System’s goal and main objectives is to achieve efficiency, effectiveness and productivity ofindividuals within an organization. Collating the responses, the HEEDS as an online integrated Information System is somehow effective and an efficient way of handling students’ transactions and records considering usability. The HEEDS as an information system may be utilized but requires updating of the processes and its features.
On the Construction of Nonsingular Pre-Big-Bang and Ekpyrotic Cosmologies and the Resulting Density Perturbations

description: We consider the construction of nonsingular Pre-Big-Bang and Ekpyrotic type cosmological models realized by the addition to the action of specific higher-order terms stemming from quantum corrections. We study models involving general relativity coupled to a single scalar field with a potential motivated by the Ekpyrotic scenario. We find that the inclusion of the string loop and quantum correction terms in the string frame makes it possible to obtain solutions of the variational equations which are nonsingular and bouncing in the Einstein frame, even when a negative exponential potential is present, as is the case in the Ekpyrotic scenario. We analyze the spectra of perturbations produced during the bouncing phase and find that the spectrum of curvature fluctuations in the model proposed originally to implement the Ekpyrotic scenario has a large blue tilt ($n_R= 3$). Except for instabilities introduced on small scales, the result agrees with what is obtained by imposing continuity of the induced metric and of the extrinsic curvature across a constant scalar field (up to $k^2$ corrections equal to the constant energy density) matching surface between the contracting and the expanding Einstein Universes. We also discuss nonsingular cosmological solutions obtained when a Gauss-Bonnet term with a coefficient suitably dependent on the scalar matter field is added to the action in the Einstein frame with a potential for the scalar field present.

description: Under the new Vision 2030 national transformation plan, the kingdom of Saudi Arabia seeks to increase number of annual pilgrims from eight million to thirty million. If oil has certain limits, then pilgrimage is framed as lasting “forever.” But this exuberant claim of “forever” belies a more subtle transformation unfolding at the level of knowledge, technology, and hospitality as Mecca and its crowds are made and re-made into a resource for a national economy. This dissertation examines the Saudi state’s efforts to manage, and ultimately intensify and optimize Mecca’s pilgrimage through new sciences and technologies of crowd management, logistics, and secular hospitality. I demonstrate how these new forms of knowledge production operate in tension with older and decidedly more Islamic ways of knowing, managing, and belonging in the holy city. Instead of approaching religious knowledge and secular knowledge as discrete spheres, my research explores their entanglements and aporias across a range of techno-political practices: navigation, hospitality, urban planning, systems thinking, crowd management, and optimization. Ultimately, I explore how in this moment of ritual intensity, the cosmopolitan logics of the holy city come to be blunted.
