Virtual Betti numbers of real algebraic varieties
McCrory, Clint; Parusinski, Adam
2002-01-01
The weak factorization theorem for birational maps is used to prove that for all nonnegative i the ith mod 2 Betti number of compact nonsingular real algebraic varieties has a unique extension to a "virtual Betti number" beta_i defined for all real algebraic varieties, such that if Y is a closed subvariety of X, then beta_i(X) = beta_i(X\\Y) + beta_i(Y).
Betty Van Dyke: The Van Dyke Ranch
Rabkin, Sarah
2010-01-01
Born in 1932 to Croatian American farmers in the Santa Clara Valley town of Cupertino, Betty Van Dyke saw her fertile home ground transformed, in a few decades, from seemingly endless orchards to unrelenting urban sprawl. As the energetic matriarch of a popular family-run fruit-growing business, she has since participated in the region’s organic agricultural renaissance, overseeing one of the first California operations to grow and dry fruit organically (becoming certified in 1986), and playi...
Obituary: Elisabetta (Betty) Pierazzo (1963-2011)
Sykes, Mark
2011-12-01
Elisabetta Pierazzo, Senior Scientist at the Planetary Science Institute, died at her home in Tucson, Arizona, on May 15. She was 47. Betty was an expert in the area of impact modeling throughout the solar system, as well as an expert on the astrobiological and environmental effects of impacts on Earth and Mars. Her work ranged widely, from providing detailed insights into the Chicxulub impact that caused the extinction of the dinosaurs to putting constraints on the thickness of the ice shell of Jupiter's moon Europa. She was interested in the rise of life and explored the delivery of organics to planets and Europa by comets as well as the creation of subsurface hydrothermal systems by impacts that may have been favorable sites for life on Mars. She was also an expert on Meteor Crater in Arizona and made several appearances on national and international broadcasts of programs including National Geographic specials, explaining the formation of this well-known structure. Betty was innovative, rigorous and systematic in her approach to science. She recognized the need for benchmarking and validating the different complex numerical codes to model impact and explosion cratering, organizing and leading a community effort to accomplish this major task. In addition to her science, Betty passionately promoted science education and public outreach. She took time away from her successful research career to teach undergraduates at the University of Arizona, she developed interactive websites and impact rock and meteorite kits for classroom use, as well as created professional development workshops for elementary and middle school science teachers. Betty arrived in the United States in 1989 from Italy and the following year attended graduate school at the Department of Planetary Sciences at the University of Arizona. She handled the difficulties of living in a foreign country by opening her house and her kitchen to others. She received her Ph.D. in 1997. The quality of her
Non-vanishingness of Betti numbers of edge ideals
Kimura, Kyouko
2011-01-01
Given finite simple graph one can associate the edge ideal. In this paper we discuss the non-vanishingness of the graded Betti numbers of edge ideals in terms of the original graph. In particular, we give a necessary and sufficient condition for a chordal graph on which the graded Betti number does not vanish and characterize the graded Betti number for a forest. Moreover we characterize the projective dimension for a chordal graph. As a result, we prove that for a chordal graph, the projective dimension of the quotient module of the edge ideal is equal to its big height.

L^2-Betti Numbers of Algebras and Equivalence Relations
2008-01-01
In this thesis, we consider the L^2-Betti numbers associated to algebras and equivalence relations. For algebras, we expand upon the motivation between Connes and Shlyakhtenko's definition of L^2-Betti numbers of tracial algebras, and give an alternative definition of these numbers through an excision-type theorem. For equivalence relations we consider the definitions given by Gaboriau and Sauer and show that they coincide, in the process proving a theorem of Gaboriau. The methods used are st...

Upper Bounds for Betti Numbers of Multigraded Modules
Beecher, Amanda
2006-01-01
This paper gives a sharp upper bound for the Betti numbers of a finitely generated multigraded $R$-module, where $R=\\Bbbk [x_{1},...,x_{m}]$ is the polynomial ring over a field $\\Bbbk$ in $m$ variables. The bound is given in terms of the rank and the first two Betti numbers of the module. An example is given which achieves these bounds simultaneously in each homological degree. Using Alexander duality, a bound is established for the total multigraded Bass numbers of a finite multigraded modul...
L2-Betti numbers of locally compact groups
Petersen, Henrik Densing
We introduce a notion of L2-Betti numbers for locally compact, second countable, unimodular groups. We study the relation to the standard notion of L2-Betti numbers of countable discrete groups for lattices. In this way, several new computations are obtained for countable groups, including lattic...... in algebraic groups over local elds, and Kac-Moody lattices. We also extend the vanishing of reduced L2-cohomology for countable amenable groups, a well known theorem due to Cheeger and Gromov, to cover all amenable, second countable, unimodular locally compact groups....

Different moment-angle manifolds arising from two polytopes having the same bigraded Betti numbers
CHOI, SUYOUNG
2012-01-01
Two simple polytopes of dimension 3 having the identical bigraded Betti numbers but non-isomorphic Tor-algebras are presented. These polytopes provide two homotopically different moment-angle manifolds having the same bigraded Betti numbers. These two simple polytopes are the first examples of polytopes that are (toric) cohomologically rigid but not combinatorially rigid.
Analysis of 2015 Meteorological Data from the Bettis Atomic Power Laboratory
Aluzzi, F. J. [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
2016-02-19
The Bettis Atomic Power Laboratory (Bettis) in West Miffin, PA is required to estimate the effects of hypothetical emissions of radiological material from its facility by the U.S. Environmental Protection Agency (EPA). An atmospheric dispersion model known as CAP88, which was developed and approved by the EPA for such purposes, is used by Bettis to meet this requirement. CAP88 calculations over a given time period are based on statistical data on the meteorological conditions for that period. The Bettis facility has an on-site meteorological tower which takes atmospheric measurements at a frequency ideal for EPA regulatory model input. However, an independent analysis and processing of the meteorological data from the site tower is required to derive a data set appropriate for use in the CAP88 model. The National Atmospheric Release Advisory Center (NARAC) was contracted by the Bettis Atomic Power Laboratory to process the on-site meteorological data for the calendar year 2015.
Domesticity in postwar America : The feminine mystique and Betty Friedan's impact on American women
2006-01-01
Betty Friedan has been celebrated as the author of the 1963 bestseller, The Feminine Mystique, a book that changed women s lives and was inspiration for the women s liberation movement. In The Feminine Mystique Betty Friedan gave a name to the frustration white middle-class women living in suburbia with 3.2 children felt. Women suddenly realized that they were not alone with their problems. Betty Friedan named the frustration that many career homemakers felt the problem that has no name, an...
Alpha, Betti and the Megaparsec Universe: on the Topology of the Cosmic Web
van de Weygaert, Rien; Edelsbrunner, Herbert; Jones, Bernard J T; Pranav, Pratyush; Park, Changbom; Hellwing, Wojciech A; Eldering, Bob; Kruithof, Nico; P., E G; Bos,; Hidding, Johan; Feldbrugge, Job; Have, Eline ten; van Engelen, Matti; Caroli, Manuel; Teillaud, Monique
2013-01-01
We study the topology of the Megaparsec Cosmic Web in terms of the scale-dependent Betti numbers, which formalize the topological information content of the cosmic mass distribution. While the Betti numbers do not fully quantify topology, they extend the information beyond conventional cosmological studies of topology in terms of genus and Euler characteristic. The richer information content of Betti numbers goes along the availability of fast algorithms to compute them. For continuous density fields, we determine the scale-dependence of Betti numbers by invoking the cosmologically familiar filtration of sublevel or superlevel sets defined by density thresholds. For the discrete galaxy distribution, however, the analysis is based on the alpha shapes of the particles. These simplicial complexes constitute an ordered sequence of nested subsets of the Delaunay tessellation, a filtration defined by the scale parameter, $\\alpha$. As they are homotopy equivalent to the sublevel sets of the distance field, they are ...

Emanating from algebraic topology and Morse theory, Betti numbers and persistence diagrams represent an extension and deepening of the cosmologically familiar topological genus measure, and the related geometric Minkowski functionals. In addition to a description of the mathematical background, this study presents the computational procedure for computing Betti numbers and persistence diagrams for density field filtrations. The field may be computed starting from a discrete spatial distribution of galaxies or simulation particles. The main emphasis of this study concerns an extensive and systematic exploration of the imprint of different weblike morphologies and different levels of multiscale clustering in the corresponding...
Betti Numbers and Degree Bounds for Some Linked Zero-Schemes
Gold, Leah; Schenck, Hal; Srinivasan, Hema
2005-01-01
In their paper on multiplicity bounds (1998), Herzog and Srinivasan study the relationship between the graded Betti numbers of a homogeneous ideal I in a polynomial ring R and the degree of I. For certain classes of ideals, they prove a bound on the degree in terms of the largest and smallest Betti numbers, generalizing results of Huneke and Miller (1985). The bound is conjectured to hold in general; we study this using linkage. If R/I is Cohen-Macaulay, we may reduce to the case where I defi...

Density functional theory (DFT) was used to study the stereochemistry, thermodynamic stability, and spectra of recently synthesized bis-Betti base derivatives of 2,3-dihydroxynaphthalene obtained through multicomponent reactions of 2,3-dihydroxynaphthalene with aminoisoxazole and benzaldehyde derivatives. The stereochemistry of the products was investigated by theoretically calculating the infrared (IR) and proton nuclear magnetic resonance ((1)H NMR) spectra of the diastereomers and comparing them to the corresponding experimental data. The thermochemical properties of the reactions, including the enthalpy, internal energy, entropy, and Gibbs free energy, were also calculated. The diastereoselectivity of the reactions was estimated from the equilibrium distribution of diastereomers. According to the results, the synthesis of bis-Betti bases is exothermic and accompanied by a decrease in entropy. The energy difference between the diastereomers is quite small, but the Gibbs free energy change for the equilibrium syn [Formula: see text] anti favors the anti over syn configuration. These results are in good agreement with experimental observations. Graphical Abstract Calculated and experimental IR spectrum for bis-Betti base 2 (mixture of anti and syn configurations).

There is interest in developing potent, selective, and cell-permeable inhibitors of human ferrous iron and 2-oxoglutarate (2OG) oxygenases for use in functional and target validation studies. The 3-component Betti reaction enables efficient one-step C-7 functionalisation of modified 8-hydroxyquinolines (8HQs) to produce cell-active inhibitors of KDM4 histone demethylases and other 2OG oxygenases; the work exemplifies how a template-based metallo-enzyme inhibitor approach can be used to give biologically active compounds.

1996 environmental monitoring report for the Bettis Atomic Power Laboratory, Pittsburgh Site
The 1996 results for the Bettis-Pittsburgh radiological and non-radiological environmental monitoring programs are presented. The primary mission of the Bettis Laboratory has been directed toward the design, development, testing, and operation of nuclear reactor propulsion plants for naval surface and submarine vessels. The results obtained from the monitoring programs demonstrate that the existing procedures ensured that releases to the environment during 1996 were in accordance with applicable federal, state, county, and local regulations. Evaluation of the environmental data indicated that the current operations at the Site continue to have no adverse effect on the quality of the environment. A conservative assessment of radiation exposure to the general public as a result of Site operations demonstrated that the dose received by any member of the public was well below the most restrictive dose limits established by the Environmental Protection Agency, the Nuclear Regulatory Commission and the US Department of Energy. A risk assessment of potentially exposed populations to chemical residues in the environment at the Site demonstrated that these residues do not pose any significant health risk

Full Text Available The article treats verbal irony in the poetry of two emblematic Estonian poets, Heiti Talvik and Betti Alver. The texts analysed are from the 1930s. Following the example of many scholars of irony, I have distinguished between two basic types of irony: verbal irony and situational irony. The first departs from the traditional definition of irony (saying one thing and meaning the contrary and centres on the use of language, on certain verbal and stylistic devices that make the receiver of the text perceive it as ironic. Situational irony refers to the recognition of the coexistence of incompatible opposites, to the feeling of the most absurd unexpectedness. The aim of the article is to locate and explain the functioning mechanisms of this verbal device in the poetry of Heiti Talvik and Betti Alver. First, there are ironies based on antonyms and/or on the negation of predication, which can be categorized as instances of classic rhetorical irony. We find in Talvik’s and Alver’s poetry few metaphors that can be explained as simple ironic metaphors (L is said but metaphorically N is meant, which in turn must be changed to its opposite value to reach the final referent N ->M=~N. Metonymy has a great inherent potential for irony: if the whole is represented by one of its parts, this often produces a mocking effect, which is the basic characteristic of irony. One can identify a particular kind of ironic metonymy in Talvik’s and Alver’s poetry when proper names (such as Casanova or Jeanne d’Arc are used to indicate certain traits (the art of living and courage, while actually meaning the opposite (triviality and cowardice. Similar to the first group of classic irony are those instances where ironic oppositions between what is said and what is meant are not based on antonyms but rather on the difference between the highest, the most valuable level, of the imaginable scale and the zero point; for example, what is said is noble, but what is meant

J. F. Powers and Betty Wahl: Irish Americans and Returning Yanks
John L. Murphy
2013-03-01
Full Text Available The limited critical attention given J.F. Powers (1917-99 has concentrated on his engagement with Catholicism. Powers also applies Irish American motifs to his fiction. This article analyzes the depiction that Powers and his wife Betty Wahl (1924-88, who left postwar America to live on and off in Ireland, made of the Irish in both their homeland and in America. Powers only once directly addressed his own experience as a sporadic Irish resident, in the final story, “Tinkers,” anthologized in his third and last collection in 1975. Wahl’s writing career proved limited. Her only novel, Rafferty and Co. (1969, semi-fictionalizes the Powers family’s decision to move to Ireland, for a series of extended stays in the 1950s and early 1960s. This article examines these writers’ dramatization of postwar Ireland as expatriate Americans. Powers’ story and Wahl’s novel depict the stresses of living in suburbs south of Dublin while struggling to sustain a countercultural yet conservative idealism. That combination drove the family away from the Midwest, in both fiction and fact, to settle in an economically destitute and patriotically insecure Ireland.

The aim was sexual and existential healing (salutogenesis) through direct confrontation and integration of both the repressed shame, guilt, and other negative feelings associated with body, genitals, and sexuality, and the repressed sexual pleasure and desire. We conducted a retrospective analysis of clinic data from holistic sexological manual therapeutic intervention, an intensive subtype of clinical holistic medicine (CHM). The patients received 3 "e 5 h of group therapy, integrating short-term psychodynamic psychotherapy (STPP) and complementary medicine (CAM bodywork, manual sexology similar to the inverted exclamation mark section signsexological examination inverted exclamation mark ). The therapy used the advanced tools of reparenting, genital acceptance, acceptance through touch, and direct sexual clitoral stimulation. A clitoral vibrator was used. Participants were 500 female patients between 18 and 88 years of age (mean of 35 years) with chronic anorgasmia (for 12 years on average) who were participating in the inverted exclamation mark section signorgasm course for anorgasmic women inverted exclamation mark ; 25% of the patients had never experienced an orgasm. Our results show that 465 patients (93%) had an orgasm during therapy, witnessed by the therapist, and 35 patients (7%) did not. Postmenopausal women were as able to achieve orgasm as fertile women, as were women who never had an orgasm. No patients had detectable negative side effects or adverse effects. NNT: 1.04 500. Therapeutic value: TV = NNH/NNT > 446. Our conclusions are that holistic sexological manual therapy may be rational, safe, ethical, and efficient. PMID:18836654

Full Text Available The objective of this study was to test the Betty Dodson method of breaking the female orgasm barrier in chronic anorgasmic women. The aim was sexual and existential healing (salutogenesis through direct confrontation and integration of both the repressed shame, guilt, and other negative feelings associated with body, genitals, and sexuality, and the repressed sexual pleasure and desire. We conducted a retrospective analysis of clinic data from holistic sexological manual therapeutic intervention, an intensive subtype of clinical holistic medicine (CHM. The patients received 3 × 5 h of group therapy, integrating short-term psychodynamic psychotherapy (STPP and complementary medicine (CAM bodywork, manual sexology similar to the “sexological examination”. The therapy used the advanced tools of reparenting, genital acceptance, acceptance through touch, and direct sexual clitoral stimulation. A clitoral vibrator was used. Participants were 500 female patients between 18 and 88 years of age (mean of 35 years with chronic anorgasmia (for 12 years on average who were participating in the “orgasm course for anorgasmic women”; 25% of the patients had never experienced an orgasm. Our results show that 465 patients (93% had an orgasm during therapy, witnessed by the therapist, and 35 patients (7% did not. Postmenopausal women were as able to achieve orgasm as fertile women, as were women who never had an orgasm. No patients had detectable negative side effects or adverse effects. NNT: 1.04 500. Therapeutic value: TV = NNH/NNT > 446. Our conclusions are that holistic sexological manual therapy may be rational, safe, ethical, and efficient.

A generalization of the formula of Fine and Rao for the ranks of the intersection homology groups of a complex algebraic variety is given. The proof uses geometric properties of intersection homology and mixed Hodge theory.
This paper details how the Bettis Atomic Power Laboratory modified and utilized a commercially available, solid carbon dioxide (CO2) pellet, non-destructive cleaning system to support the disposition and disposal of radioactive waste from shielded hot cells. Some waste materials and equipment accumulated in the shielded hot cells cannot be disposed directly because they are contaminated with transuranic materials (elements with atomic numbers greater than that of uranium) above waste disposal site regulatory limits. A commercially available CO2 pellet non-destructive cleaning system was extensively modified for remote operation inside a shielded hot cell to remove the transuranic contaminants from the waste and equipment without generating any secondary waste in the process. The removed transuranic contaminants are simultaneously captured, consolidated, and retained for later disposal at a transuranic waste facility

Full Text Available En este artículo analizo la obra capital de Betty Friedan, The Feminine Mystique (1963. Exploro sus descripciones del ama de casa que dedi- ca su trabajo, energía y su vida adulta a su marido, hijos y hogar. El estudio de Friedan sobre la cuestión de la mano de obra doméstica de la esposa se basó en una mezcla de posturas marxistas de la vieja izquierda de la preguerra y la creciente influencia de la ideología liberal dominante antirradical de la década de 1950, conforme acadé- micos y comentaristas sociales contemporáneos habían articulado es- tas visiones. El ensayo examina cómo el enfoque social, psicológico y económico de Friedan subvirtió y validó de manera simultánea a las ciencias sociales y las ideologías rivales de la época. El hecho de cruzar fronteras le permitió a Friedan convertirse en una “figura puen- te transicional” entre generaciones.

贝蒂·弗里丹是美国女权运动史上的领军人物之一，她在20世纪60年代前后的主要女性主义思想于《女性的奥秘》一书中得到了充分而详尽的呈现。在这部美国女性主义经典著作中，弗里丹揭露了女性奥秘论的本质，解构了源自美国主流文化的歧视性性别话语，并鼓励美国女性争取作为完备的人类所应享有的生活。弗里丹在这一历史阶段中的女性主义思想于美国内外以实现性别平等为目标的斗争而言，均发挥了重要而积极的作用。%Betty Friedan is one of the leading figures in the history of American feminist movements, and her main feminist ideas around the 1960s are fully reflected in"The Feminine Mystique". In this classic of American feminism, Friedan reveals the essence of the feminine mystique, deconstructs the discriminatory gender discourse generated by American mainstream culture, and en-courages American women to strive for the lives of complete hu-man beings. Her feminist ideas in this historical period have been playing a significant and positive role in the struggle for gender equality both inside and outside the United States.
L^2-Betti numbers of coamenable quantum groups
Kyed, David
2007-01-01
We prove that a compact quantum group is coamenable if and only if its corepresentation ring is amenable. We further propose a Foelner condition for compact quantum groups and prove it to be equivalent to coamenability. Using this Foelner condition, we prove that for a coamenable compact quantum group with tracial Haar state, the enveloping von Neumann algebra is dimension flat over the Hopf algebra of matrix coefficients. This generalizes a theorem of Lueck from the group case to the quantum...

Flashes of patterned wallpaper, whiskey neat, babies born that are never mentioned, contact lining for kitchen drawers, Ayn Rand, polaroids, skinny ties, Hilton hotels, Walter Cronkite, and a time when Don Draper can ask ‘What do women want?’ and dry old Roger Sterling can reply ‘Who Cares?’ This essay explores the embrace of period detail in Mad Men finding it to be both loving and fetishistic, and belonging, like all period film, to the politics of the present.
Betti numbers and stability for configuration spaces via factorization homology
Knudsen, Ben
2014-01-01
Using factorization homology, we realize the rational homology of the unordered configuration spaces of an arbitrary manifold $M$, possibly with boundary, as the homology of a Lie algebra constructed from the compactly supported cohomology of $M$. By locating the homology of each configuration space within the Chevalley-Eilenberg complex of this Lie algebra, we extend theorems of B\\"{o}digheimer-Cohen-Taylor and F\\'{e}lix-Thomas and give a new, combinatorial proof of the homological stability...

Children in the United Kingdom watch more television and are exposed to more advertising than children in any other European country. This article investigates the extent to which preschool children (aged 4-5 years) prefer brands advertised on television. Seventy-five children were interviewed and given a choice task in which they had to select the product, from eight pairs each comprising a branded and nonbranded product, that children of their own age and gender preferred. Products included popular drinks, snacks, toys, breakfast cereals, and sportswear. Nonbranded control products were carefully selected as close perceptual matches for the branded advertised products. Yet, on 68% of occasions, children chose the branded, advertised product in preference to the nonbranded product. This preference was reliably higher for girls (78%) than boys (58%). Gender-linked differences are discussed in relation to socialization theory and to girls' greater verbal ability and emotional sensitivity. PMID:12915793

The purpose of this note is to give a refinement of the product formula proved in [1] for the Poincare polynomial of a smooth Schubert variety in the flag variety of an algebraic group G over C. This yields a factorization of the number of elements in a Bruhat interval [e,w] in the Weyl group W of G provided the Schubert variety associated to w is smooth. This gives an elementary necessary condition for a Schubert variety in the flag variety to be smooth.

Full Text Available Objetivou-se propor uma estratégia de atenção para usuário de crack, por meio da aplicação do Processo de Enfermagem. Trata-se de estudo de caso, descritivo e exploratório com abordagem qualitativa, fundamentado em Neuman e em NANDANIC-NOC. O cenário foi o Centro de Atenção Psicossocial - Álcool e Drogas de Vitória-ES. Aplicou-se o questionário do padrão de consumo de crack, Escala de Gravidade de Dependência, Mini Internacional Neuropsychiatric Interview e Parental Bonding Instrument. Constatou-se a complexidade das situações relativas aos estressores intra, inter e extrapessoais. Foram discutidos três diagnósticos: 'conhecimento deficiente sobre o controle do uso de substâncias', 'enfrentamento ineficaz' e 'isolamento social', e sugeridas intervenções por meio de articulação entre a NIC, a NOC e a prevenção secundária de Neuman. Assim, é função primordial do enfermeiro: mobilizar os recursos do sistema - internos e externos - para estabilização e conservação da energia, de forma a fortalecer as linhas de resistência, além de considerar todas as variáveis do sistema e não só o uso do crack.

Latina women are vulnerable to poor body image, eating disorders, and obesity, particularly during the college years. This study sought to identify common cultural antecedents of these concerns in order to inform the development of prevention programs for this population. Six groups of university students who identified as Latina (N=27) discussed cultural aspects of body image, eating disorders, and obesity. Thematic analysis identified four main themes: (a) cultural disparities in body-ideal, including the influence of the media and acculturation issues; (b) messages about body shape and weight received by family, peers, and society; (c) difficulties making healthy eating and physical activity choices as a function of college life; and (d) the influence of peers and potential male partners on body satisfaction and body-ideals. These results have implications for the development of programs targeting body dissatisfaction and risk for eating disorders and obesity in Latina college women. PMID:22609033

在无溶剂无催化剂条件下,无论是含有吸电子基团还是含有供电子基团的芳香醛都能与2-萘酚以及仲胺反应,短时间内以高产率生成氨基烷基萘酚.该方法实验操作简单,不需要使用催化剂和溶剂,减少了废物排放,降低了成本,是一种绿色合成氨基烷基萘酚的方法.%Aromatic aldehyde containing electron-donating and electron-withdrawing substituents was reacted with 2-naphthol and secondary amine to furnish aminoalkylnaphthols in short time with high yield under solvent-free conditions in the absence of catalyst. The advantages of these reactions were simplicity of the reaction procedure, simple work-up, catalyst-and solvent-free conditions, reducing the amount of waste, and lower cost. The present method provides a green route for synthesis of aminoalkylnaphthols.

Betti numbers of configuration spaces of mechanical linkages (known also as polygon spaces) depend on a large number of parameters -- the lengths of the bars of the linkage.

We establish a surprising fact that for a reasonably ample class of sequences of ...

L^2-homology for compact quantum groups
Kyed, David

A notion of L^2-homology for compact quantum groups is introduced, generalizing the classical notion for countable, discrete groups. If the compact quantum group in question has tracial Haar state, it is possible to define its L^2-Betti numbers and Novikov-Shubin invariants/capacities. It is proved that these L^2-Betti numbers vanish for the Gelfand dual of a compact Lie group and that the zeroth Novikov-Shubin invariant equals the dimension of the underlying Lie group. Finally, we relate our...
Modification of the resonance treatment in multigroup neutron slowing-down codes
The previously reported computer codes GRACE and BETTY for resonance treatment in the multigroup neutron slowing-down processes have been improved, employing the new results of resonance absorption calculations. The total resonance integral formulae were changed, 239Pu resonance integral data were included in the library of group constants and the selection of partial resonance integral distribution functions was automatized. The users of the GRACE and BETTY codes are provided with a more credible and more comfortable resonance treatment. Explicit description of modification of user's manuals is given. (D.P.)
Poincaré Polynomial of the Moduli Spaces of Parabolic Bundles
Yogish I Holla
2000-08-01
In this paper we use Weil conjectures (Deligne's theorem) to calculate the Betti numbers of the moduli spaces of semi-stable parabolic bundles on a curve. The quasi parabolic analogue of the Siegel formula, together with the method of Harder-Narasimhan filtration gives us a recursive formula for the Poincaré polynomials of the moduli. We solve the recursive formula by the method of Zagier, to give the Poincaré polynomial in a closed form. We also give explicit tables of Betti numbers in small rank, and genera.

We introduce a notion of a sheaf of vector spaces on a graph, and develop the foundations of homology theories for such sheaves. One sheaf invariant, its "maximum excess," has a number of remarkable properties. It has a simple definition, with no reference to homology theory, that resembles graph expansion. Yet it is a "limit" of Betti numbers, and hence has a short/long exact sequence theory and resembles the $L^2$ Betti numbers of Atiyah. Also, the maximum excess is defined via a supermodul...

A remark on an algebraic Riemann-Roch formula for flat bundles
Esnault, H
1997-01-01
We propose an algebraic Riemann-Roch formula for moving flat bundles on contant families in characteristic zero with values in the ring of algebraic differential characters. This formula lifts Grothendieck-Riemann-Roch formula in the Chow groups and Bismut-Lott formula in the odd dimensional Betti cohomology with $\\C/\\Z$ coefficients over the field of complex numbers.

Sheaves on Graphs and Their Homological Invariants
Friedman, Joel
2011-01-01
We introduce a notion of a sheaf of vector spaces on a graph, and develop the foundations of homology theories for such sheaves. One sheaf invariant, its "maximum excess," has a number of remarkable properties. It has a simple definition, with no reference to homology theory, that resembles graph expansion. Yet it is a "limit" of Betti numbers, and hence has a short/long exact sequence theory and resembles the $L^2$ Betti numbers of Atiyah. Also, the maximum excess is defined via a supermodular function, which gives the maximum excess much stronger properties than one has of a typical Betti number. The maximum excess gives a simple interpretation of an important graph invariant, which will be used to study the Hanna Neumann Conjecture in a future paper. Our sheaf theory can be viewed as a vast generalization of algebraic graph theory: each sheaf has invariants associated to it---such as Betti numbers and Laplacian matrices---that generalize those in classical graph theory.

Mathematical Physics in Italy in the XIX Century: The Theory of Elasticity
Capecchi, Danilo
In the second half of the nineteenth century there was in Italy an important group of mathematicians who focused their attention on mathematical physics. The most prominent of them were Enrico Betti, Eugenio Beltrami, Gregorio Ricci-Curbastro and some others (Vito Volterra, Carlo Somigliana and Tullio Levi Civita) whose activity persevered for many years in the twentieth century. In this article, I will write about the contribution of this group to the theory of elasticity. The best representative writing on continuum mechanics and elasticity as theories of mathematical physics is presented in the book Teoria della elasticità by Enrico Betti. The book is interesting not only for the particular results found but also for its structure which became paradigmatic for the development of subsequent texts on elasticity, not only those in Italian. Betti's interest was concentrated on the mathematical aspects of a physical theory. Physical principles are not discussed; they are only exposed in the most formal way possible. The objective is to arrive, without discussing epistemological or empirical problems, at the formulation and solution of differential equations that rule elasticity, as had become classic in the emerging mathematical physics. Beltrami wrote no complete books on elasticity; however, his contribution to this field was perhaps more original than that of Betti. A similar consideration holds true for Volterra and Somigliana.

Cohomology of line bundles: Proof of the algorithm
We present a proof of the algorithm for computing line bundle valued cohomology classes over toric varieties conjectured by Blumenhagen et al. [e-print arXiv:cond-mat/1003.5217] and suggest a kind of Serre duality for combinatorial Betti numbers that we observed when computing examples.
On the cohomology and instantons number in E-infinity Cantorian spacetime
El Naschie, M.S. [Frankfurt Institute of Advanced Studies, Frankfurt (Germany); Department of Astrophysics, Faculty of Science, University of Cairo, Cairo (Egypt)
2005-10-01
The paper deals with the cohomology and instantons number in E-infinity space. It is found that E-infinity may be described by a fuzzy hyperbolic manifold. The Betti numbers of this manifold lead to the conclusion that the Euler characteristic of this manifold is {chi} {approx_equal} 26 and that this is equal to the number of instantons.

I am thankful to Lucy Skaer for her thoughtful answers and to Henry VIII’s Wives for permission to present their video and filmic work.The interview serves to introduce an artist portfolio containing three videos – Spiral Betty, Mr. Hysteria, and The Returning Officer – by the art collective Henry VIII’s Wives.
The L2-cohomology of Discrete Groups
Schreve, Kevin
Given a space with a proper, cocompact group action, the L2-cohomology groups are a particularly interesting invariant that incorporates the topology of the space and the geometry of the group action. We are interested in both the algebraic and geometric aspects of these invariants. From the algebraic side, the Strong Atiyah Conjecture claims that the L2-Betti numbers assume only rational values, with certain prescribed denominators related to the torsion subgroups of the group. We prove this conjecture for the class of virtually cocompact special groups. This implies the Zero Divisor Conjecture holds for such groups. On the geometric side, the Action Dimension Conjecture claims that a group with that acts properly on a contractible n-manifold has vanishing L2-Betti numbers above the middle dimension. We will prove this conjecture for many classes of right-angled Artin groups and Coxeter groups.

Twilight of the Grrrls: Stephenie Meyer’s Rehash of the Feminine Mystique
Casarini, Alice
2015-01-01
In spite of the abundance of powerful female leads in recent media productions, Stephenie Meyer’s Twilight saga (2005-2008) signaled a relapse into the ideology of the feminine mystique, famously addressed in Betty Friedan's eponymous volume (1963). By analyzing Meyer's portrayal of protagonist Bella Swan's utter lack of agency, this paper explores the ways in which the saga rehashes and perpetuates an age-old Weltanschauung in which women find their natural self-fulfillment through marriage ...

Complex Geometry of Nuclei and Atoms
Atiyah, M F
2016-01-01
We propose a new geometrical model of matter, in which neutral atoms are modelled by compact, complex algebraic surfaces. Proton and neutron numbers are determined by a surface's Chern numbers. Equivalently, they are determined by combinations of the Hodge numbers, or the Betti numbers. Geometrical constraints on algebraic surfaces allow just a finite range of neutron numbers for a given proton number. This range encompasses the known isotopes.

Overview of the history of neutronics computations
This paper provides some background and perspective on the history of neutronics computations. The author started his carerr at Bettis Atomic Power Laboratory (BAPL) in 1954. At that time, computers were primitive and unfamiliar to most of us. Bettis did own an IBM Card Programmed Computer, which, as its name suggested, had a punched-card memory, and some of the industry's first cross-section preparation codes (the early MUFTs) were written for this machine by Ben Mount. There was also at BAPL another digital machine, which spewed output everywhere on punched tape. But the laboratory's most powerful machine was an analog computer that solved two-group diffusion equations in two dimensions. An excellent physicist of that period argued that analog machines were the wave of the future because digital computers could never solve the diffusion equation in two dimensions. At the time, this seemed like a very reasonable prediction; yet it was not very long before Bettis was renting time on UNIVACs all over the country precisely to solve the two-dimensional diffusion equation. Since then, we have learned that it is always risky to predict future trends in the computer industry

In Betty's Brain, students instruct a character called a Teachable Agent (TA) which can reason based on how it is taught. Two studies demonstrate the protégé effect: students make greater effort to learn for their TAs than they do for themselves. The first study involved 8th-grade students learning biology. Although all students worked with the same Betty's Brain software, students in the TA condition believed they were teaching their TAs, while in another condition, they believed they were learning for themselves. TA students spent more time on learning activities (e.g., reading) and also learned more. These beneficial effects were most pronounced for lower achieving children. The second study used a verbal protocol with 5th-grade students to determine the possible causes of the protégé effect. As before, students learned either for their TAs or for themselves. Like study 1, students in the TA condition spent more time on learning activities. These children treated their TAs socially by attributing mental states and responsibility to them. They were also more likely to acknowledge errors by displaying negative affect and making attributions for the causes of failures. Perhaps having a TA invokes a sense of responsibility that motivates learning, provides an environment in which knowledge can be improved through revision, and protects students' egos from the psychological ramifications of failure.
K-theory of locally finite graph C∗-algebras
Iyudu, Natalia
2013-09-01
We calculate the K-theory of the Cuntz-Krieger algebra OE associated with an infinite, locally finite graph, via the Bass-Hashimoto operator. The formulae we get express the Grothendieck group and the Whitehead group in purely graph theoretic terms. We consider the category of finite (black-and-white, bi-directed) subgraphs with certain graph homomorphisms and construct a continuous functor to abelian groups. In this category K0 is an inductive limit of K-groups of finite graphs, which were calculated in Cornelissen et al. (2008) [3]. In the case of an infinite graph with the finite Betti number we obtain the formula for the Grothendieck group K0(OE)=Z, where β(E) is the first Betti number and γ(E) is the valency number of the graph E. We note that in the infinite case the torsion part of K0, which is present in the case of a finite graph, vanishes. The Whitehead group depends only on the first Betti number: K1(OE)=Z. These allow us to provide a counterexample to the fact, which holds for finite graphs, that K1(OE) is the torsion free part of K0(OE).
This book discusses the GAO's work on the Naval Reactors Program's environmental, health, and safety practices at its research and development facilities, the Knolls Atomic Power Laboratory near Schenectady, New York; the Bettis Atomic Power Laboratory near Pittsburgh, Pennsylvania; and their related reactor sites. This review was conducted because of several allegations concerning poor environmental, health, and safety practices at the facilities. These allegations involved employee over-exposures to radiation, reactor safety, asbestos problems, and improper management of areas containing radioactive and hazardous waste. In summary the review of the environmental, health, and safety practices at the Naval Reactors laboratories and sites has found no significant deficiencies

Closed forms and multi-moment maps
Madsen, Thomas Bruun
2011-01-01
We extend the notion of multi-moment map to geometries defined by closed forms of arbitrary degree. We give fundamental existence and uniqueness results and discuss a number of essential examples, including geometries related to special holonomy. For forms of degree four, multi-moment maps are guaranteed to exist and are unique when the symmetry group is (3,4)-trivial, meaning that the group is connected and the third and fourth Lie algebra Betti numbers vanish. We give a structural description of some classes of (3,4)-trivial algebras and provide a number of examples.

The formulation of reverberation-ray matrix analysis has been proposed to study wave propagation in planar frames. It is applied here to modal analysis of complex three-dimensional framed structures, optionally with lumped masses and/or elastic supports. Furthermore, by means of Betti's reciprocity theorem, orthogonal conditions are established for different natural modes, and hence transient response analysis based on mode superposition is developed. Both the reverberation-ray matrix analysis for free vibration and the mode superposition method for transient response are illustrated by numerical examples.

On the structure of Stanley-Reisner rings associated to cyclic polytopes
Boehm, Janko
2009-01-01
We study the structure of Stanley-Reisner rings associated to cyclic polytopes, using ideas from unprojection theory. Consider the boundary simplicial complex Delta(d,m) of the d-dimensional cyclic polytope with m vertices. We show how to express the Stanley-Reisner ring of Delta(d,m+1) in terms of the Stanley-Reisner rings of Delta(d,m) and Delta(d-2,m-1). As an application, we use the Kustin-Miller complex construction to identify the minimal graded free resolutions of these rings. In particular, we recover results of Schenzel, Terai and Hibi about their graded Betti numbers.
Quantum algorithms for topological and geometric analysis of data.
Lloyd, Seth; Garnerone, Silvano; Zanardi, Paolo
2016-01-01
Extracting useful information from large data sets can be a daunting task. Topological methods for analysing data sets provide a powerful technique for extracting such information. Persistent homology is a sophisticated tool for identifying topological features and for determining how such features persist as the data is viewed at different scales. Here we present quantum machine learning algorithms for calculating Betti numbers--the numbers of connected components, holes and voids--in persistent homology, and for finding eigenvectors and eigenvalues of the combinatorial Laplacian. The algorithms provide an exponential speed-up over the best currently known classical algorithms for topological data analysis. PMID:26806491
Pseudo-Anosov extensions and degree one maps between hyperbolic surface bundles
Boileau, Michel; NI, YI; Wang, Shicheng
2005-01-01
Let $F',F$ be any two closed orientable surfaces of genus $g'>g\\ge 1$, and $f:F\\to F$ be any pseudo-Anosov map. Then we can "extend" $f$ to be a pseudo-Anosov map $f':F'\\to F'$ so that there is a fiber preserving degree one map $M(F',f')\\to M(F,f)$ between the hyperbolic surface bundles. Moreover the extension $f'$ can be chosen so that the surface bundles $M(F',f')$ and $M(F,f)$ have the same first Betti numbers.

Nursing theory: the 21st century.
Randell, B P
1992-01-01
On September 21, 1990, at the University of California, Los Angeles, Neuropsychiatric Institute and Hospital, six nurse theorists participated in a panel discussion on theory development for the 21st century. The theorists included Dorothy Johnson, Betty Neuman, Dorothea E. Orem, Rosemarie Rizzo Parse, Martha E. Rogers and Callista Roy. The panel provided the participants the opportunity to speculate on the course for future development of nursing knowledge. Three questions were posed to the panel relating to the development of their models, the direction nursing theory will take in the 21st century, and current research emerging from the extant theories. The panel also addressed questions from the audience. PMID:1454278
In search of applications of nursing theories: the Nursing Citation Index.
Johnson, E D
1989-04-01
Cited author searches were conducted in Nursing Citation Index to determine its utility in locating clinical studies that apply the conceptual frameworks of Dorothea Orem, Callista Roy, Martha Rogers, Betty Neuman, and Dorothy Johnson. Fully 75 percent of the relevant papers would have been missed by a conventional subject/textword search in the MEDLINE or CINAHL databases. Had Nursing Citation Index not been available, only 22 percent of relevant papers could have been retrieved by cited author searches of Social Science Citation Index. In summary, Nursing Citation Index provides an important indexing link between nursing theory and nursing research. PMID:2655783
An Additive Basis for the Chow Ring of $overline{mathcal M}_{0,2}({mathbb P}^r,2$
Jonathan A. Cox
2007-08-01
Full Text Available We begin a study of the intersection theory of the moduli spaces of degree two stable maps from two-pointed rational curves to arbitrary-dimensional projective space. First we compute the Betti numbers of these spaces using Serre polynomial and equivariant Serre polynomial methods developed by E. Getzler and R. Pandharipande. Then, via the excision sequence, we compute an additive basis for their Chow rings in terms of Chow rings of nonlinear Grassmannians, which have been described by Pandharipande. The ring structure of one of these Chow rings is addressed in a sequel to this paper.

Topology of configuration space of two particles on a graph, II
Farber, Michael
2010-01-01
This paper continues the investigation of the configuration space of two distinct points on a graph. We analyze the process of adding an additional edge to the graph and the resulting changes in the topology of the configuration space. We introduce a linking bilinear form on the homology group of the graph with values in the cokernel of the intersection form (introduced in Part I of this work). For a large class of graphs, which we call mature graphs, we give explicit expressions for the Betti numbers of the configuration space. We show that under a simple condition, adding an edge to a mature graph yields another mature graph.

The inverted flag instability occurs when a pliable plate is held parallel to a free-stream, with the leading edge free to move and the trailing edge clamped. Large-amplitude flapping is observed across a slim band of non-dimensional wind speeds. This specific boundaries of this flapping band vary greatly, depending on both the aspect ratio and the angle of attack of the plate with respect to the incoming flow. In addition, both periodic and aperiodic flapping modes exist. The frequency of the plate motion was analyzed and was found to be consistent with vortex-induced vibration. This research is supported by the Gordon and Betty Moore Foundation.
A non-commutative Path Space approach to stationary free Stochastic Differential Equations
Dabrowski, Yoann
2010-01-01
By defining tracial states on a non-commutative analogue of a path space, we construct Markov dilations of certain conservative completely Markov semigroups on finite von Neumann algebras. For well chosen semigroups they solve certain stationary free SDEs previously considered by D. Shlyakhtenko. Among applications, we prove a non-commutative Talagrand's inequality for non-microstate free entropy. We also use those new deformations in conjunction with Popa's deformation/rigidity techniques. For instance, combining our results with techniques of Popa-Ozawa and Peterson, we prove that the von Neumann algebra of a countable discrete group with CMAP and positive first L^2 Betti number has no Cartan subalgebras.

Identifying coverage holes makes an important topic for optimization of quality service for wireless sensor network hosts. This paper introduces a new way to identify and describe how is the network's structure, its number of holes and its components, assuming there's a sensor covering an area where a network communication exists. The simplicial complex method and algebraic graph theory will be applied. Betti numbers and Euler characteristics will be used for a sensor network represented by a simplicial complex, and the Tutte polynomial will be used for describing visual graphs algebraically, for a complete identification.

Denoting by $g$ the first Betti number of $\\overline \\Omega$ the idea is to find, first $g$ different $1$-boundaries of $\\overline{\\Omega}$ with supports contained in $\\partial\\Omega$ whose homology classes in $\\mathbb R^3 \\setminus \\Omega$ form a basis of $H_1(\\mathbb R^3 \\setminus \\Omega;\\mathbb Z)$, and then to construct in $\\...
Let ZLMO be the 3-manifold invariant of [LMO]. It is shown that ZLMO(M) = 1, if the first Betti number of M, b1 (M), is greater than 3. If b1 (M) = 3, then ZLMO (M) is completely determined by the cohomology ring of M. A relation of ZLMO with the Rozansky-Witten invariants ZXRW[M] is established at a physical level of rigour. We show that ZXRW[M] satisfies appropriate connected sum properties suggesting that the generalized Casson invariant ought to be computable from the LMO invariant. (author)

We introduce a notion of moment map adapted to actions of Lie groups that preserve a closed three-form. We show existence of our multi-moment maps in many circumstances, including mild topological assumptions on the underlying manifold. Such maps are also shown to exist for all groups whose second...... and third Lie algebra Betti numbers are zero. We show that these form a special class of solvable Lie groups and provide a structural characterisation. We provide many examples of multi-moment maps for different geometries and use them to describe manifolds with holonomy contained in G(2) preserved by...
Cohomological orientifold Donaldson-Thomas invariants as Chow groups
Franzen, Hans
2016-01-01
We establish a geometric interpretation of orientifold Donaldson-Thomas invariants of $\\sigma$-symmetric quivers with involution. More precisely, we prove that the cohomological orientifold Donaldson-Thomas invariant is isomorphic to the rational Chow group of the moduli space of $\\sigma$-stable self-dual quiver representations. As an application we prove that the Chow Betti numbers of moduli spaces of stable $m$-tuples in classical Lie algebras can be computed numerically. We also prove a cohomological wall-crossing formula relating semistable Hall modules for different stabilities.
Embedding Seifert manifolds in S^4
Donald, Andrew
2012-01-01
Using an obstruction based on Donaldson's theorem on the intersection forms of definite 4-manifolds, we determine which connected sums of lens spaces smoothly embed in S^4. We also find constraints on the Seifert invariants of Seifert 3-manifolds which embed in S^4 when either the base orbifold is non-orientable or the first Betti number is odd. In addition we construct some new embeddings and use these, along with the d and mu-bar invariants, to examine the question of when the double branched cover of a 3 or 4 strand pretzel link embeds.
Alexander Duals of Multipermutohedron Ideals
Ajay Kumar; Chanchal Kumar
2014-02-01
An Alexander dual of a multipermutohedron ideal has many combinatorial properties. The standard monomials of an Artinian quotient of such a dual correspond bijectively to some -parking functions, and many interesting properties of these Artinian quotients are obtained by Postnikov and Shapiro (Trans. Am. Math. Soc. 356 (2004) 3109–3142). Using the multigraded Hilbert series of an Artinian quotient of an Alexander dual of multipermutohedron ideals, we obtained a simple proof of Steck determinant formula for enumeration of -parking functions. A combinatorial formula for all the multigraded Betti numbers of an Alexander dual of multipermutohedron ideals are also obtained.

2012-01-01
This paper discusses the use of betti numbers to characterize fingerprint and iris images. The goal is to automatically separate fingerprint images from non-fingerprint images; where non-fingerprint images of special interest are biometric samples which are not fingerprints. In this regard...... numbers of “n” prototype images in order to perform classification (“fingerprint” vs “non-fingerprint”). The proposed method is compared against SIVV (a tool provided by NIST). Experimental results on fingerprint and iris databases demonstrate the potential of the scheme....
Cohomology of toric line bundles via simplicial Alexander duality
Jow, Shin-Yao
2011-03-01
We give a rigorous mathematical proof for the validity of the toric sheaf cohomology algorithm conjectured in the recent paper by Blumenhagen, Jurke, Rahn, and Roschy (arXiv:1003.5217). We actually prove not only the original algorithm but also a speed-up version of it. Our proof is independent from (in fact appeared earlier on the arXiv than) the proof by Roschy and Rahn (arXiv:1006.2392), and has several advantages such as being shorter and cleaner and can also settle the additional conjecture on "Serre duality for Betti numbers" which was raised but unresolved in arXiv:1006.2392.
Physicist appeals against security revoke
Gwynne, Peter
2009-01-01
An Egyptian-born nuclear physicist filed a fresh legal appeal last month in an effort to learn why his security clearance was revoked by the US Department of Energy (DOE). Abdel Moniem El-Ganayni, 57, who became a US citizen in 1988, lost his clearance in December 2007. Last May, he lost his job at Bettis Laboratory in Pittsburgh, which is run for the DOE by a subsidiary of the Bechtel Corporation. A lawsuit in which El-Ganayni sought a hearing on the reasons for revoking his clearance was dismissed in late November by US District judge Terrence McVerry, prompting the latest appeal.

Effects of Processing on Wheat Tortilla Quality: Benefits of Hard White Wheat
Michael Tilley; Valquiria Pierucci; Katherine A Tilley; Okkyung Kim Chung
2006-01-01
The suitability of Kansas hard white winter (HWW) wheat milled at a high extraction rate for tortilla production was investigated. All of the Kansas varieties of white wheat, milled to 80% extraction, performed as well as, if not better than, a standard commercial tortilla flour milled to 72% extraction when various quality factors were compared. Tortillas were made from eight wheat cultivars milled at 80% extraction: four HWW wheat cultivars included Betty, Heyne, Oro Blanco and NuWest; three hard red winter (HRW) wheat samples were Jagger and Ike grown at Hutchinson, Kansas (Ike-Hutch) and at Hays, Kansas (Ike-Hays); and one hard white spring (HWS) wheat cultivar, Idaho 377-S. Tortillas made from these flours were compared to tortillas made from one commercial tortilla-flour milled to 72% extraction from a blend of HRW wheat. Mixograph parameters, starch pasting properties,dough-handling characteristics and tortilla- making attributes of the new Kansas HWW wheat cultivars, Betty and Heyne, were superior. In summary, Kansas HWW wheat flours, milled to 80% extraction, produced tortillas which were equal to, or superior to,those made from 80%-extraction HRW wheat flours and 72%-extraction commercial tortilla flour.
Implementation of a New DTSTEP Algorithm for use in RELAP5-3D and PVMEXEC Completion Report
Dr. George L Mesina
2010-12-01
The PVM Coupling methodology for decomposing a complex model into domains onto which individual programs may be applied has proven effective for solving many multi-physics problems. There have been, from the outset, some detailed and/or long-running models that cause the process to fail. This project addressed the PVM coupling issues surrounding the DTSTEP subroutines on RELAP5-3D and PVMEXEC. Some 25 errors are listed in Tables 1 and 18 and in Section 11. These arise from deficiencies in the floating point calculation and testing of time steps, cumulative time, and time targets. The algorithmic replacement of floating point control of these items with integer based timestepping was developed and implemented. The result of the first phase, undertaken by the INL was that all but three of these issues were resolved. Moreover, two conceptual errors in DTSTEP that were not PVM coupling related were discovered and solved. The final, and most difficult three PVM Bettis User Problems, were solved during the Bettis phase of development and debugging. In 8 months since the conclusion of the project, no further DTSTEP related PVM Coupling errors have been reported.
Efficient Computation of the Topology of Level Sets
Pascucci, V; Cole-McLaughlin, K
2002-07-19
This paper introduces two efficient algorithms that compute the Contour Tree of a 3D scalar field F and its augmented version with the Betti numbers of each isosurface. The Contour Tree is a fundamental data structure in scientific visualization that is used to pre-process the domain mesh to allow optimal computation of isosurfaces with minimal storage overhead. The Contour Tree can be also used to build user interfaces reporting the complete topological characterization of a scalar field, as shown in Figure 1. In the first part of the paper we present a new scheme that augments the Contour Tree with the Betti numbers of each isocontour in linear time. We show how to extend the scheme introduced in 3 with the Betti number computation without increasing its complexity. Thus we improve on the time complexity from our previous approach 8 from 0(m log m) to 0(n log n+m), where m is the number of tetrahedra and n is the number of vertices in the domain of F. In the second part of the paper we introduce a new divide and conquer algorithm that computes the Augmented Contour Tree for scalar fields defined on rectilinear grids. The central part of the scheme computes the output contour tree by merging two intermediate contour trees and is independent of the interpolant. In this way we confine any knowledge regarding a specific interpolant to an oracle that computes the tree for a single cell. We have implemented this oracle for the trilinear interpolant and plan to replace it with higher order interpolants when needed. The complexity of the scheme is O(n + t log n), where t is the number of critical points of F. This allows for the first time to compute the Contour Tree in linear time in many practical cases when t = O(n{sup 1-e}). We report the running times for a parallel implementation of our algorithm, showing good scalability with the number of processors.
Key Factors Influencing the Decision on the Number of Brayton Units for the Prometheus Space Reactor
Ashcroft, John; Belanger, Sean; Burdge, Wayne; Clementoni, Eric; Jensen, Krista; Proctor, N. Beth; Zemo-Fulkerson, Annie
2007-01-01
The Naval Reactors (NR) Program and its DOE Laboratories, KAPL and Bettis, were assigned responsibility to develop space reactor systems for the Prometheus Program. After investigating all of the potential reactor and energy conversion options, KAPL and Bettis selected a direct gas Brayton system as the reference approach for the nuclear electric propulsion missions, including the Jupiter Icy Moons Orbiter (JIMO). In order to determine the optimal plant architecture for the direct gas system, KAPL and Bettis investigated systems with one or two active Brayton units and up to two spare units. No final decision was made on the optimal system configuration for the NEP gas-Brayton system prior to closeout of the project. The two most promising options appear to be a single system without spares and a three Brayton system with two operating units, each producing half of the required load, with a single spare unit. The studies show that a single Brayton system, without spares, offers the lowest mass system, with potential for lower operating temperature, and a minimum of system and operational complexity. The lower required mass and increased system efficiency inherent in the single Brayton system may be exploited to satisfy other design objectives such as reduced reactor and radiator operating temperatures. While Brayton system lifetimes applicable to a JIMO or other nuclear electric propulsion (NEP) mission have not been demonstrated, there is no fundamental limit on the lifetime of the Brayton hardware. Use of additional Brayton units with installed spares will allow for continued operation in the event of a failure of an individual Brayton unit. However, preliminary system reliability evaluations do not point to any substantial reliability benefit provided by carrying spare Brayton units. If a spare unit is used, operating two of the units at full power with an unpowered spare proved more efficient than operating all three units at a reduced power and temperature
Parallel Computation of the Topology of Level Sets
Pascucci, V; Cole-McLaughlin, K
2004-12-16
This paper introduces two efficient algorithms that compute the Contour Tree of a 3D scalar field F and its augmented version with the Betti numbers of each isosurface. The Contour Tree is a fundamental data structure in scientific visualization that is used to preprocess the domain mesh to allow optimal computation of isosurfaces with minimal overhead storage. The Contour Tree can also be used to build user interfaces reporting the complete topological characterization of a scalar field, as shown in Figure 1. Data exploration time is reduced since the user understands the evolution of level set components with changing isovalue. The Augmented Contour Tree provides even more accurate information segmenting the range space of the scalar field in portion of invariant topology. The exploration time for a single isosurface is also improved since its genus is known in advance. Our first new algorithm augments any given Contour Tree with the Betti numbers of all possible corresponding isocontours in linear time with the size of the tree. Moreover we show how to extend the scheme introduced in [3] with the Betti number computation without increasing its complexity. Thus, we improve on the time complexity from our previous approach [10] from O(m log m) to O(n log n + m), where m is the number of cells and n is the number of vertices in the domain of F. Our second contribution is a new divide-and-conquer algorithm that computes the Augmented Contour Tree with improved efficiency. The approach computes the output Contour Tree by merging two intermediate Contour Trees and is independent of the interpolant. In this way we confine any knowledge regarding a specific interpolant to an independent function that computes the tree for a single cell. We have implemented this function for the trilinear interpolant and plan to replace it with higher order interpolants when needed. The time complexity is O(n + t log n), where t is the number of critical points of F. For the first time
Radiochemical studies in support of the low level waste ocean disposal program (East Coast Site)
This report describes the final year of field work for the Low Level Waste Ocean Disposal program. The goal of the work has been to describe the extent and rates of scavenging of naturally occurring radionuclides at the Bettis east coast site. In order to characterize the extent of chemical removal of radionuclides from the oceanic water column, data are required on the partitioning between particles and solution, on the fluxes of particles (and radionuclides) through the water column, and on the amount (or inventory) of nuclide accumulated in bottom sediment at the site. This information was collected through analyses of samples taken with in situ pumps, sediment traps and gravity and box cores
This report describes the outcome of a Pacific Ocean research program begun in November 1978 by Sandia National Laboratories for the Bettis Atomic Power Laboratory. The six-year oceanographic program was in support of a US Navy environmental evaluation of possible sea disposal of defueled, decommissioned, nuclear-powered submarines. Evaluation guidelines were written to define a site suitable for such sea disposal. This final report, which combines results from two previous progress reports and data from recently completed studies, characterizes a suitable site, the West Coast, Northern Site (W-N). Although W-N is neither the only possible nor the best Pacific site, it is one suitable location under the site evaluation guidelines. 95 refs., 29 figs., 10 tabs
On the topology of the level sets of a scalar field
Pascucci, V
2000-12-12
This paper introduces a new simple algorithm for the construction of the Contour Tree of a 3D scalar field augmented with the Betti numbers of each contour component. The algorithm has {Omicron}(n log n) time complexity and {Omicron}(n) auxiliary storage. where n is the number of vertices in the domain of the field. The algorithm can be applied to fields of any dimension in which case it computes the Contour Tree augmented, with the Euler characteristic of each contour. The complexity in any dimension remains {Omicron}(n logn). This is the same complexity as in [4] but with correct computation of the tree for fields with bounded domains.
PWSCC crack growth rate of alloy 690 to simulate actual plant material
In order to understand the PWSCC crack growth rate of domestically produced alloy 690, alloy 690 materials were obtained from two companies which supply materials that are used in actual plants. PWSCC crack growth rates of cold worked alloy TT690 were measured under simulated PWR primary water conditions. The crack growth rates of 20% cold-worked alloy TT690 from both companies were less than 5×10-11 m/s, and the crack growth rates were not as fast as reported from Bettis. Also it was observed that there was up to about 2.5 times difference in the crack growth rates of TT690 of the two companies. (author)

Edna Mara da Silva de Souza
2013-12-01
Full Text Available The textual construction already stated Bakhtin (2006 is permeated with intertextuality, ie a text takes from other texts, from this perspective, this study examines the intertextuality and the representation of narrative structure presented by students who participated in the workshops creative production of texts after storytime at the Centre for Studies in Reading and Children's and Youth Literature Betty Maria Coelho Silva (CELLIJ at UNESP campus of Presidente Prudente - SP. This paper presents a reflection on the importance of offering new narratives, whether through storytelling or reading literary texts, to build the child repertoire. From the reading of the corpus nine selected texts, we observed a strong influence of the heroes of commercial films and television series in child production, as well as a tendency writing conditional structure of fairy tales.
[Effects of the preparation on anxiety before bronchoscopy].
Léophonte, P; Delon, S; Dalbiès, S; Fontes-Carrère, M; de Carvalho, E G; Lepage, S
2000-03-01
In their daily practice, the nurses note the patients' anxiety when they are in hospital for diagnosis exams. Considering this observation, we wanted to assess the potential benefits provided by the behavioural and relational techniques, such as sophrology, maintenance of the help relation, visualization-relaxation. In order to carry out this survey, we adopted the model of Betty NEUMAN, who relies on the concept of homeostasis and on the stress theory of Hans Seyle. The measurement of anxiety by the STAI (State Trait Anxiety Inventory), a scale worked out by SPIELBERGER, enabled us to prove that these relational tools, used by the nurses, made it possible for the patients to better mobilize their adjustment or coping strategies. Recommendations concerning the management of anxiety were set out as not to trigger an attitude of vigilant coping. PMID:10897742
Global anomalies in six dimensions
Applying Witten's formula for global gauge and gravitational anomalies to six dimensional supergravities, we find: (a) The perturbatively anomaly free N=4 chiral supergravity coupled to 21 tensor multiplets is global anomaly free for any choice of space-time manifold with vanishing third Betti number (b3). (b) The perturbatively anomaly free matter coupled N=2 chiral supergravities with arbitrary number of tensor multiplets, whose Yang-Mills gauge groups do not include G2, SU(2), or SU(3) are free of global anomalies if the theory is formulated on S6. In the case of 9 tensor multiplets coupled to supergravity this result holds for any spacetime with vanishing b3. (c) The N=6 chiral supergravity has perturbative gravitational anomalies, and therefore the global anomalies need not be considered in this case. (author)
Community-local homology of force chains in granular materials
Giusti, Chad; Owens, Eli; Daniels, Karen; Bassett, Danielle
2015-03-01
The development of robust quantitative measurements of the structure of force chains in granular materials remains an open problem. Recent work of Bassett, et. al. applies community detection algorithms to extract subnetworks of strongly interacting particles, and then computes geometric measures of these networks to characterize local branching. Separately, Kramar, et. al. apply persistent homology to extract robust global signatures of chains in terms of their Betti numbers. Here, we investigate a hybrid of these two approaches, computing low-dimensional persistent homology of the clique complexes of communities in force-chain graphs. Such invariants measure the tendency of core chain sections to branch while remaining insensitive to the presence of tightly-packed collections of particles, thus making them natural candidates for both local and global stability analysis.
OAK-B135 A rising load test in low-temperature (50-100 degree C) pH 10 water containing a high concentration of dissolved hydrogen (150 cc/kg) has demonstrated that Alloy 690 as well as weld metals 82 and 52 exhibit a marked loss of ductility. A similar loss of ductility has been shown to occur in widely used weld metal 182 under replica test conditions and simulated PWR primary water containing 100 cc/kg of hydrogen. The objective of this report was to confirm the Bettis test results for weld metal 82 and determine whether weld metal 182 is susceptible to the same reductions in toughness. This report documents the first industry effort to reckon with the low temperature crack propagation (LTCP) issue
Integral identities for a semi-infinite interfacial crack in anisotropic elastic bimaterials
Morini, L; Mishuris, G; Radi, E
2012-01-01
The focus of the article is on analysis of a semi-infinite crack at the interface between two dissimilar anisotropic elastic materials, loaded by a general asymmetrical system of forces acting on the crack faces. Recently derived symmetric and skew-symmetric weight functions matrices are introduced for both plane strain and antiplane shear cracks, and used together with the fundamental reciprocal identity (Betti formula) in order to formulate the elastic fracture problem in terms of singular integral equations relating the applied loading and the resulting crack opening. The proposed compact formulation can be used to solve many problems in linear elastic fracture mechanics (for example various classic crack problems in homogeneous and heterogeneous media). This formulation is also fundamental in many multiphysics applications, where the elastic problem is coupled with other concurrent physical phenomena.
Study on Electrospinning Silk Fibroin Solution
LI Ni; QIN Xiao-hong; WANG Shan-yuan
2007-01-01
A new method of preparing silk fibroin (SF) solution used in the electerospinning was introduced in this paper. According to the method, SF was dissolved in the LiBr/CH2O2 solution directly at room temperature. The method was compared with the traditional method---SF was dissolved in CaCl2 ternary solution. The structure of SF films and the morphology of SF nanofibers were examined by attenuated total reflectance fourier transform intrared (ATR- FrlR) spectroscopy, Scanning electron microscope (SEM) and optical polarizing microscope. The result of this study shows that the new method is a faster, more convenient and high efficient way to get the SF solution and the characteristics of SF fibet made by the new method is much betty.

A model-of three-dimensional lattice gravity
In this paper, a model is proposed which generates all oriented 3D simplicial complexes weighted with an invariant associated with a topological lattice gauge theory. When the gauge group is SUq(2), qn = 1, it is the Turaev-Viro invariant and the model may be regarded as a non-perturbative definition of 3D simplicial quantum gravity. If one takes a finite Abelian group G, the corresponding invariant gives the rank of the first cohomology group of a complex C: IG(C) = rank (H1(C,G)), which means a topological expansion in the Betti number b1. In general, it is a theory of the Dijkgraaf-Witten type, i.e., determined completely by the fundamental group of a manifold
Fuel Summary Report: Shippingport Light Water Breeder Reactor - Rev. 2
Olson, Gail Lynn; Mc Cardell, Richard Keith; Illum, Douglas Brent
2002-09-01
The Shippingport Light Water Breeder Reactor (LWBR) was developed by Bettis Atomic Power Laboratory to demonstrate the potential of a water-cooled, thorium oxide fuel cycle breeder reactor. The LWBR core operated from 1977-82 without major incident. The fuel and fuel components suffered minimal damage during operation, and the reactor testing was deemed successful. Extensive destructive and nondestructive postirradiation examinations confirmed that the fuel was in good condition with minimal amounts of cladding deformities and fuel pellet cracks. Fuel was placed in wet storage upon arrival at the Expended Core Facility, then dried and sent to the Idaho Nuclear Technology and Engineering Center for underground dry storage. It is likely that the fuel remains in good condition at its current underground dry storage location at the Idaho Nuclear Technology and Engineering Center. Reports show no indication of damage to the core associated with shipping, loading, or storage.

On May 12, 1989, in Pittsburgh, six nurse leaders participated in a panel discussion on health at Discovery International, Inc.'s Nurse Theorist Conference. The participants were Imogene King, Nola Pender, Betty Neuman, Martha E. Rogers, Afaf Meleis and Rosemarie Rizzo Parse. The goal of the conferences was to present views on the meaning of health from different perspectives. The panel discussion provided the nurse leaders with an opportunity to engage in a dialogue about health. Five of the participants answered the questions posed and the conference keynote speaker Afaf Meleis responded. Four questions were posed to the panel relating to the meaning of health, the uniqueness of nursing, and nurse-person relationships. The dialogue of the panel discussion follows. PMID:2000198
A Banach space-valued ergodic theorem for amenable groups and applications
Pogorzelski, Felix
2012-01-01
In this paper we study unimodular amenable groups. The first part is devoted to results on the existence of uniform families of quasi tilings for these groups. In light of that, constructions of Ornstein and Weiss are extended by quantitative estimates for the covering properties of the corresponding decompositions. Afterwards, we apply the developed methods to obtain an abstract ergodic theorem for a class of functions mapping subsets of the group into some Banach space. Moreover, applications of this convergence result are studied: the uniform existence of the integrated density of states (IDS) for operators on amenable Cayley graphs; the uniform existence of the IDS for operators on discrete structures being quasi-isometric to some amenable group; the approximation of L2-Betti numbers on cellular CW-complexes; the existence of certain densities of clusters in a percolated Cayley graph.
Local non-Calderbank-Shor-Steane quantum error-correcting code on a three-dimensional lattice
We present a family of non-Calderbank-Shor-Steane quantum error-correcting code consisting of geometrically local stabilizer generators on a 3D lattice. We study the Hamiltonian constructed from ferromagnetic interaction of overcomplete set of local stabilizer generators. The degenerate ground state of the system is characterized by a quantum error-correcting code whose number of encoded qubits are equal to the second Betti number of the manifold. These models (i) have solely local interactions; (ii) admit a strong-weak duality relation with an Ising model on a dual lattice; (iii) have topological order in the ground state, some of which survive at finite temperature; and (iv) behave as classical memory at finite temperature.
A critical analysis of Neuman's systems model in relation to public health nursing.
Haggart, M
1993-12-01
The public health movement is an old discipline being given new life and meaning based on a recognition of continuing health problems associated with social inequalities. The 'new public health' movement has goals which are closely aligned to those of the World Health Organization in their Health for All by 2000 initiative which represent a collective approach to health in contrast to the current political emphasis on individual responsibility for health. Public health nursing is a relatively new concept in Britain but posts are beginning to be established in many areas where nurses are working in partnership with communities in a public health capacity. At a time when this area of nursing is in its relative infancy it is appropriate to develop a clear philosophy and framework and to examine potential strategies. This paper sets out to contribute to the development of this discipline by critically analysing the work of Betty Neuman to determine its utility for public health nursing. PMID:8132923
Integral identities for a semi-infinite interfacial crack in 2D and 3D elasticity
Piccolroaz, Andrea
2011-01-01
The paper is concerned with the problem of a semi-infinite crack at the interface between two dissimilar elastic half-spaces, loaded by a general asymmetrical system of forces distributed along the crack faces. On the basis of the weight function approach and the fundamental reciprocal identity (Betti formula), we formulate the elasticity problem in terms of singular integral equations relating the applied loading and the resulting crack opening. Such formulation is fundamental in the theory of elasticity and extensively used to solve several problems in linear elastic fracture mechanics (for instance various classic crack problems in homogeneous and heterogeneous media). This formulation is also crucial in important recent multiphysics applications, where the elastic problem is coupled with other concurrent physical phenomena. A paradigmatic example is hydraulic fracturing, where the elasticity equations are coupled with fluid dynamics.
Persistent Homology of Collaboration Networks
C. J. Carstens
2013-01-01
Full Text Available Over the past few decades, network science has introduced several statistical measures to determine the topological structure of large networks. Initially, the focus was on binary networks, where edges are either present or not. Thus, many of the earlier measures can only be applied to binary networks and not to weighted networks. More recently, it has been shown that weighted networks have a rich structure, and several generalized measures have been introduced. We use persistent homology, a recent technique from computational topology, to analyse four weighted collaboration networks. We include the first and second Betti numbers for the first time for this type of analysis. We show that persistent homology corresponds to tangible features of the networks. Furthermore, we use it to distinguish the collaboration networks from similar random networks.
High-density carbon ablator ignition path with low-density gas-filled rugby hohlraum
Amendt, Peter; Ho, Darwin D.; Jones, Ogden S. [Lawrence Livermore National Laboratory, Livermore, California 94551 (United States)
2015-04-15
A recent low gas-fill density (0.6 mg/cc {sup 4}He) cylindrical hohlraum experiment on the National Ignition Facility has shown high laser-coupling efficiency (>96%), reduced phenomenological laser drive corrections, and improved high-density carbon capsule implosion symmetry [Jones et al., Bull. Am. Phys. Soc. 59(15), 66 (2014)]. In this Letter, an ignition design using a large rugby-shaped hohlraum [Amendt et al., Phys. Plasmas 21, 112703 (2014)] for high energetics efficiency and symmetry control with the same low gas-fill density (0.6 mg/cc {sup 4}He) is developed as a potentially robust platform for demonstrating thermonuclear burn. The companion high-density carbon capsule for this hohlraum design is driven by an adiabat-shaped [Betti et al., Phys. Plasmas 9, 2277 (2002)] 4-shock drive profile for robust high gain (>10) 1-D ignition performance and large margin to 2-D perturbation growth.

We use a normal-mode formalism to compute the response of a spherical, self-gravitating anelastic PREM-like Earth model to various excitation sources at the Slichter mode period. The formalism makes use of the theory of the Earth's free oscillations based upon an eigenfunction expansion methodology. We determine the complete response in the form of Green's function obtained from a generalization of Betti's reciprocity theorem. Surficial (surface load, fluid core pressure), internal (earthquakes, explosions) and external (object impact) sources of excitation are investigated to show that the translational motion of the inner-core would be best excited by a pressure acting at the core boundaries at time-scales shorter than the Slichter eigenperiods.
Characterization of a vortical gust generator using PIV
Hufstedler, Esteban; McKeon, Beverley
2015-11-01
A heaving plate has been used to generate aperiodic vortical gusts in a free-surface water tunnel as part of an effort to experimentally investigate the interaction between a wing and an incoming parallel vortex. Particle image velocimetry measurements provided information about the growth and evolution of the vortices over a range of heaving and freestream speeds. Vortex tracking methods were used to examine the circulation and movement paths of the vortices. Preliminary results of vortex-airfoil interactions will also be presented, with a view to identifying the gust response and tolerance. This work was supported by the Gordon and Betty Moore Foundation through grant GBMF #2645 to the California Institute of Technology.

2008-01-01
At the forefront of the development of electronic modules, the DEM group provides continuous support for the engineers and technicians of the LHC experiments. The DEM group produced 400 electronic circuit boards needed for checking the LHC accelerating cavities at Point 4. The TS-DEM group is a closely knit community. From left to right: Betty Magnin (section leader of the design office and cabling workshop), Erik van der Bij (group leader), Rui de Oliveira, section leader of PMT (production of printed circuits). Like all the accelerator components, the accelerating cavities that will give the protons the necessary "kick" as they hurtle their way around the ring are brimming with electronics, but their control electronics are highly specific. The challenge of producing the associated electronic boards, which were designed by the AB-RF group, was taken up by the TS Department’s Development of...
Flow Behavior Around Coupled, Rotating Turbines in Steady Flow
Fu, Matthew; Dabiri, John
2012-11-01
Counter-rotating vertical axis turbines (VATs) have been shown to yield increased power density in wind farms as compared to typical horizontal axis wind turbine (HAWT) farms. However, the governing physical mechanisms remain poorly understood. Scale model experiments in a free-surface water tunnel were conducted to characterize the effect of parameters such as turbine separation, tip speed ratio, and flow speed on the downstream flow field and the resulting vortex shedding from VATs. The flow field was visualized using particle image velocimetry (PIV) and planar laser induced fluorescence. The results are compared and contrasted with recent studies of counter-rotating circular cylinders to determine if suppression of vortex shedding plays a similarly important role in dictating the overall wake dynamics. This research was made possible through the generosity of Gordon and Betty Moore Foundation and the Caltech SURF Program.
Dynamic Chord-wise Tip Curvature on Flexible Flapping Plates
Martin, Nathan; Gharib, Morteza
2014-11-01
The aerodynamic characteristics of long rectangular flapping plates are strongly influenced by the interaction between tip and edge vortices. This has led to the development of many tip actuation mechanisms to independently bend or rotate the tip towards the root of the plate in the span-wise direction. In our current work, the influence of dynamically altering the chord-wise curvature of the tip on the generation of aerodynamic forces is investigated; for this case, the two free corners of the flat plate bend towards each other. The parameters of actuation timing, maximum curvature, Reynolds number, flexibility, and tip speed are independently varied to determine their influence. These results will further the fundamental understanding of unsteady aerodynamics. This material is based upon work supported by the National Science Foundation Graduate Research Fellowship and the Gordon and Betty Moore foundation.

This volume of the LLE Review, covering October-December 2000, begins with an article by R. Betti, M. Umansky, V. Lobatchev, V. N. Goncharov, and R. L. McCrory, who report on the development of a model for the deceleration phase of an imploding inertial fusion capsule (p. 1). The model shows that the ablative flow off the inner shell surface plays a critical role in reducing the growth rate and suppressing short-wavelength modes in the deceleration-phase Rayleigh-Taylor instability.

Cohomology of quasiperiodic patterns and matching rules
Quasiperiodic patterns described by polyhedral 'atomic surfaces' are considered. It is shown that under certain rationality conditions (which coincide with the necessary conditions for the existence of matching rules), the cohomology ring of the continuous hull of such patterns is isomorphic to that of the complement of a torus TN to an arrangement A of thickened affine tori of codimension 2. Explicit computation of Betti numbers for several two-dimensional tilings and for the icosahedral Ammann-Kramer tiling confirms in most cases the results obtained previously by different methods. The cohomology groups of TN/A have a natural structure of a right module over the group ring of the space symmetry group of the pattern and can be decomposed in a direct sum of its irreducible representations. An example of such decomposition is shown for the Ammann-Kramer tiling

Quasiperiodic patterns described by polyhedral 'atomic surfaces' are considered. It is shown that under certain rationality conditions (which coincide with the necessary conditions for the existence of matching rules), the cohomology ring of the continuous hull of such patterns is isomorphic to that of the complement of a torus T{sup N} to an arrangement A of thickened affine tori of codimension 2. Explicit computation of Betti numbers for several two-dimensional tilings and for the icosahedral Ammann-Kramer tiling confirms in most cases the results obtained previously by different methods. The cohomology groups of T{sup N}/A have a natural structure of a right module over the group ring of the space symmetry group of the pattern and can be decomposed in a direct sum of its irreducible representations. An example of such decomposition is shown for the Ammann-Kramer tiling.

When hydrodynamically scaled to the energy of the National Ignition Facility, these implosions achieved a Lawson parameter ˜60 % of the value required for ignition [A. Bose et al., Phys. Rev. E 93, LM15119ER (2016)], similar to indirect-drive implosions [R. Betti et al., Phys. Rev. Lett. 114, 255003 (2015)], and nearly half of the direct-drive ignition-threshold pressure. Relative to symmetric, one-dimensional simulations, the inferred hot-spot pressure is approximately 40% lower. Three-dimensional simulations suggest that low-mode distortion of the hot spot seeded by laser-drive nonuniformity and target-positioning error reduces target performance.
This report presents two detailed computerized operating procedures developed to assist and control the shearing and dissolution of irradiated fuel rods. The procedures were employed in the destructive analysis of end-of-life fuel rods from the Light Water Breeder Reactor (LWBR) that was designed by the Westinghouse Electric Corporation Bettis Atomic Power Laboratory. Seventeen entire fuel rods from the end-of-life core of the LWBR were sheared into 169 precisely characterized segments, and more than 150 of these segments were dissolved during execution of the LWBR Proof-of-Breeding (LWBR-POB) Analytical Support Project at Argonne National Laboratory. The procedures illustrate our approaches to process monitoring, data reduction, and quality assurance during the LWBR-POB work

Analytic Torsion, 3d Mirror Symmetry And Supergroup Chern-Simons Theories
Mikhaylov, Victor
2015-01-01
We consider topological field theories that compute the Reidemeister-Milnor-Turaev torsion in three dimensions. These are the psl(1|1) and the U(1|1) Chern-Simons theories, coupled to a background complex flat gauge field. We use the 3d mirror symmetry to derive the Meng-Taubes theorem, which relates the torsion and the Seiberg-Witten invariants, for a three-manifold with arbitrary first Betti number. We also present the Hamiltonian quantization of our theories, find the modular transformations of states, and various properties of loop operators. Our results for the U(1|1) theory are in general consistent with the results, found for the GL(1|1) WZW model. We also make some comments on more general supergroup Chern-Simons theories.
The Shippingport Pressurized Water Reactor and Light Water Breeder Reactor
This report discusses the Shippingport Atomic Power Station, located in Shippingport, Pennsylvania, which was the first large-scale nuclear power plant in the United States and the first plant of such size in the world operated solely to produce electric power. A program was started in 1953 at the Bettis Laboratory to confirm the practical application of nuclear power for large-scale electric power generation. It led to the development of zirconium alloy (Zircaloy) clad fuel element containing bulk actinide oxide ceramics (UO2, ThO2, ThO2 -- UO2, ZrO2 -- UO2) as nuclear reactor fuels. The program provided much of the technology being used for design and operation of the commercial, central-station nuclear power plants now in use. The Shippingport Pressurized Water Reactor (PWR) began initial power operation on December 18, 1957, and was a reliable electric power producer until February 1974. In 1965, subsequent to the successful operation of the Shippingport PWR (UO2, ZrO2 -- UO2 fuels), the Bettis Laboratory undertook a research and development program to design and build a Light Water Breeder Reactor (LWBR) core for operation in the Shippingport Station. Thorium was the fertile fuel in the LWBR core and was the base oxide for ThO2 and ThO2 -- UO2 fuel pellets. The LWBR core was installed in the pressure vessel of the original Shippingport PWR as its last core before decommissioning. The LWBR core started operation in the Shippingport Station in the autumn of 1977 and finished routine power operation on October 1, 1982. Successful LWBR power operation to over 160% of design lifetime demonstrated the performance capability of the core for both base-load and swing-load operation. Postirradiation examinations confirmed breeding and successful performance of the fuel system

The technology of breeding /sup 233/U from /sup 232/Th in a light water reactor is being developed and evaluated by the Westinghouse Bettis Atomic Power Laboratory (BAPL) through operation and examination of the Shippingport Light Water Breeder Reactor (LWBR). Bettis is determining the end-of-life (EOL) inventory of fissile uranium in the LWBR core by nondestructive assay of a statistical sample comprising approximately 500 EOL fuel rods. This determination is being made with an irradiated-fuel assay gauge based on neutron interrogation and detection of delayed neutrons from each rod. The EOL fissile inventory will be compared with the beginning-of-life fissile loading of the LWBR to determine the extent of breeding. In support of the BAPL proof-of-breeding (POB) effort, Argonne National Laboratory (ANL) carried out destructive physical, chemical, and radiometric analyses on 17 EOL LWBR fuel rods that were previously assayed with the nondestructive gauge. The ANL work included measurements on the intact rods; shearing of the rods into pre-designated contiguous segments; separate dissolution of each of the more than 150 segments; and analysis of the dissolver solutions to determine each segment's uranium content, uranium isotopic composition, and loading of selected fission products. This report describes the facilities in which this work was carried out, details operations involved in processing each rod, and presents a comprehensive discussion of uncertainties associated with each result of the ANL measurements. Most operations were carried out remotely in shielded cells. Automated equipment and procedures, controlled by a computer system, provided error-free data acquisition and processing, as well as full replication of operations with each rod. Despite difficulties that arose during processing of a few rod segments, the ANL destructive-assay results satisfied the demanding needs of the parent LWBR-POB program.

Full Text Available Daniele da Volterra is better known in Spain for painting the drapery that covers some of the nudes in Michelangelo’s The Last Judgment than for his own work, which defined him as his master’s most loyal successor. Nonetheless, Daniele’s influence on Spanish art through Gaspar Becerra, a disciple of his in Rome, determined to a large extent the development of sculpture in this country in the second half of the 16th century. This article makes known and discusses Daniele’s previously unpublished last will and testament, located in the Archivio di Stato di Roma among the volumes by the notary Thomassino, who attended to the inventory of his possessions. It also provides new details on Daniele’s estate and on his direct disciples Michele Alberti, Feliciano de San Vito, and Biagio Betti along with his indirect ones such as Jacopo Rocchetti.

Resolution of stringy singularities by non-commutative algebras
In this paper we propose a unified approach to (topological) string theory on certain singular spaces in their large volume limit. The approach exploits the non-commutative structure of D-branes, so the space is described by an algebraic geometry of non-commutative rings. The paper is devoted to the study of examples of these algebras. In our study there is an auxiliary commutative algebraic geometry of the center of the (local) algebras which plays an important role as the target space geometry where closed strings propagate. The singularities that are resolved will be the singularities of this auxiliary geometry. The singularities are resolved by the non-commutative algebra if the local non-commutative rings are regular. This definition guarantees that D-branes have a well defined K-theory class. Homological factors also play an important role. They describe the intersection theory of D-branes and lead to a formal definition of local quivers at singularities, which can be computed explicitly for many types of singularities. These results can be interpreted in terms of the derived category of coherent sheaves over the non-commutative rings, giving a non-commutative version of recent work by M. Douglas. We also describe global features like the Betti numbers of compact singular Calabi-Yau threefolds via global holomorphic sections of cyclic homology classes. (author)
Morse Set Classification and Hierarchical Refinement Using Conley Index
Guoning Chen,
2012-05-01
Morse decomposition provides a numerically stable topological representation of vector fields that is crucial for their rigorous interpretation. However, Morse decomposition is not unique, and its granularity directly impacts its computational cost. In this paper, we propose an automatic refinement scheme to construct the Morse Connection Graph (MCG) of a given vector field in a hierarchical fashion. Our framework allows a Morse set to be refined through a local update of the flow combinatorialization graph, as well as the connection regions between Morse sets. The computation is fast because the most expensive computation is concentrated on a small portion of the domain. Furthermore, the present work allows the generation of a topologically consistent hierarchy of MCGs, which cannot be obtained using a global method. The classification of the extracted Morse sets is a crucial step for the construction of the MCG, for which the Poincar index is inadequate. We make use of an upper bound for the Conley index, provided by the Betti numbers of an index pair for a translation along the flow, to classify the Morse sets. This upper bound is sufficiently accurate for Morse set classification and provides supportive information for the automatic refinement process. An improved visualization technique for MCG is developed to incorporate the Conley indices. Finally, we apply the proposed techniques to a number of synthetic and real-world simulation data to demonstrate their utility. © 2006 IEEE.
A topological study of repetitive co-activation networks in in vitro cortical assemblies
To address the issue of extracting useful information from large data-set of large scale networks of neurons, we propose an algorithm that involves both algebraic-statistical and topological tools. We investigate the electrical behavior of in vitro cortical assemblies both during spontaneous and stimulus-evoked activity coupled to Micro-Electrode Arrays (MEAs). Our goal is to identify core sub-networks of repetitive and synchronous patterns of activity and to characterize them. The analysis is performed at different resolution levels using a clustering algorithm that reduces the network dimensionality. To better visualize the results, we provide a graphical representation of the detected sub-networks and characterize them with a topological invariant, i.e. the sequence of Betti numbers computed on the associated simplicial complexes. The results show that the extracted sub-populations of neurons have a more heterogeneous firing rate with respect to the entire network. Furthermore, the comparison of spontaneous and stimulus-evoked behavior reveals similarities in the identified clusters of neurons, indicating that in both conditions similar activation patterns drive the global network activity.
