    OpenAIRE

    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).

    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

  9. Non-vanishingness of Betti numbers of edge ideals

    CERN Document Server

    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.

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...

    DEFF Research Database (Denmark)

    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....

    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.

    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 ...

    We introduce a multiscale topological description of the Megaparsec weblike cosmic matter distribution. Betti numbers and topological persistence offer a powerful means of describing the rich connectivity structure of the cosmic web and of its multiscale arrangement of matter and galaxies. 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...

  8. Betti Numbers and Degree Bounds for Some Linked Zero-Schemes

    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...

    2016-04-01

    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).

    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

  3. Verbaalsest irooniast Heiti Talviku ja Betti Alveri luule näitel. Verbal irony in the poetry of Heiti Talvik and Betti Alver

    2012-06-01

    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

  5. J. F. Powers and Betty Wahl: Irish Americans and Returning Yanks

    Directory of Open Access Journals (Sweden)

    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.

  6. Clinical holistic medicine: teaching orgasm for females with chronic anorgasmia using the Betty Dodson method.

    2008-01-01

    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 "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

  11. Use of a CO2 pellet non-destructive cleaning system to decontaminate radiological waste and equipment in shielded hot cells at the Bettis Atomic Power Laboratory

    International Nuclear Information System (INIS)

    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.

    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...

    Pine, Karen J; Nash, Avril

    2003-08-01

    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.

    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

    OpenAIRE

    Farber, Michael

    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. Motivated by applications in topological robotics, statistical shape theory and molecular biology, we view these lengths as random variables and study asymptotic values of the average Betti numbers as the number of links n tends to infinity. We establish a surprising fact that for a reasonably ample class of sequences of ...

The Betti numbers of the binomial ideal and its natural initial ideal coincide and they correspond to the number of 'connected flags' in the graph. In particular the Betti numbers are ...

  13. L^2-homology for compact quantum groups

    OpenAIRE

    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...

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.)

  15. Poincaré Polynomial of the Moduli Spaces of Parabolic Bundles

    Indian Academy of Sciences (India)

    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.

    CERN Document Server

    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.

  12. Mathematical Physics in Italy in the XIX Century: The Theory of Elasticity

    Science.gov (United States)

    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.

    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.

    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.

  1. The L2-cohomology of Discrete Groups

    Science.gov (United States)

    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.

    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 ...

(2) There exist two simplicial complexes with equal bigrade...

    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.

  2. Overview of the history of neutronics computations

    International Nuclear Information System (INIS)

    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

  3. Teachable Agents and the Protégé Effect: Increasing the Effort Towards Learning

    Science.gov (United States)

    Chase, Catherine C.; Chin, Doris B.; Oppezzo, Marily A.; Schwartz, Daniel L.

    2009-08-01

    Betty's Brain is a computer-based learning environment that capitalizes on the social aspects of learning. 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.

  4. K-theory of locally finite graph C∗-algebras

    Science.gov (United States)

    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

    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.

  9. Dynamic analysis of space frames: The method of reverberation-ray matrix and the orthogonality of normal modes

    Science.gov (United States)

    Guo, Y. Q.; Chen, W. Q.; Pao, Y.-H.

    2008-11-01

    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.

    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.

    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

    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.

    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

    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.

    Directory of Open Access Journals (Sweden)

    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.

  1. Properties of thoria and thoria-urania: a review (LWBR Development Program)

    International Nuclear Information System (INIS)

    Information on the physical, chemical, and mechanical properties of thoria and thoria-urania is reviewed and assessed. The properties discussed are those judged to be important for an understanding of the behavior of these oxides as nuclear fuel materials. Evaluation was made, where possible, of the effects of composition, material variables, temperature, and irradiation exposure. Data were taken from a review of the literature and from both published and unpublished data derived from the Light Water Breeder Reactor (LWBR) Program at the Bettis Atomic Power Laboratory. 30 figs., 23 tables, 163 refs

  2. Topology of configuration space of two particles on a graph, II

    CERN Document Server

    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.

  5. A non-commutative Path Space approach to stationary free Stochastic Differential Equations

    CERN Document Server

    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.

    2010-04-01

    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.

  8. The universal perturbative quantum 3-manifold invariant, Rozansky-Witten invariants, and the generalized Casson invariant

    International Nuclear Information System (INIS)

    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...

  10. Cohomological orientifold Donaldson-Thomas invariants as Chow groups

    CERN Document Server

    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.

  11. 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.

  12. 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.

    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....

    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.

    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.

    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.

  19. Implementation of a New DTSTEP Algorithm for use in RELAP5-3D and PVMEXEC Completion Report

    Energy Technology Data Exchange (ETDEWEB)

    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.

  20. Efficient Computation of the Topology of Level Sets

    Energy Technology Data Exchange (ETDEWEB)

    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.

  1. Key Factors Influencing the Decision on the Number of Brayton Units for the Prometheus Space Reactor

    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

    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

  3. Radiochemical studies in support of the low level waste ocean disposal program (East Coast Site)

    International Nuclear Information System (INIS)

    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

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

    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.

  6. PWSCC crack growth rate of alloy 690 to simulate actual plant material

    International Nuclear Information System (INIS)

    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)

    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

  9. Global anomalies in six dimensions

    International Nuclear Information System (INIS)

    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)

  10. Community-local homology of force chains in granular materials

    Science.gov (United States)

    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.

  11. Materials Reliability Program Low-Temperature Cracking of Nickel-Based Alloys and Weld Metals (MRP-108)

    International Nuclear Information System (INIS)

    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.

    CERN Document Server

    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.

    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.

  15. A model-of three-dimensional lattice gravity

    International Nuclear Information System (INIS)

    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

  16. 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

  18. A Banach space-valued ergodic theorem for amenable groups and applications

    CERN Document Server

    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.

  19. Local non-Calderbank-Shor-Steane quantum error-correcting code on a three-dimensional lattice

    International Nuclear Information System (INIS)

    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.

  20. A critical analysis of Neuman's systems model in relation to public health nursing.

    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

  1. Integral identities for a semi-infinite interfacial crack in 2D and 3D elasticity

    CERN Document Server

    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.

  2. Persistent Homology of Collaboration Networks

    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.

    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.

  6. Excitation of the Slichter mode by collision with a meteoroid or pressure variations at the surface and core boundaries

    Rosat, S; 10.1016/J.PEPI.2011.10.007

    2012-01-01

    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.

    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.

    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.

  10. 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.

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.

  15. Cohomology of quasiperiodic patterns and matching rules

    International Nuclear Information System (INIS)

    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

    A record fuel hot-spot pressure Phs=56 ±7 Gbar was inferred from x-ray and nuclear diagnostics for direct-drive inertial confinement fusion cryogenic, layered deuterium-tritium implosions on the 60-beam, 30-kJ, 351-nm OMEGA Laser System. 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.

    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.

  1. The Shippingport Pressurized Water Reactor and Light Water Breeder Reactor

    International Nuclear Information System (INIS)

    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 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.

  8. Resolution of stringy singularities by non-commutative algebras

    International Nuclear Information System (INIS)

    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)

  9. Morse Set Classification and Hierarchical Refinement Using Conley Index

    KAUST Repository

    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.

  10. A topological study of repetitive co-activation networks in in vitro cortical assemblies

    International Nuclear Information System (INIS)

    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.

    Full Text Available Rabindranath Tagore's Educational Philosophy Generally, Western philosophy of education comprises two schools, traditional and modern. It has its roots in Athens, Rome and Judeo-Christianity, whilst Tagore's philosophy of education draws its inspiration from ancient Indian philosophy of education. However, it could be said that Tagore's philosophy of education may become a representation of the Eastern philosophy apart from others like Islam, Confucianism, Taoism, and Mahayana Buddhism. By looking on Western countries and India, both countries have distinct differences in their ways of developing and shaping an individual, in terms of skills and attitudes. Thus, different cultures will have different philosophies, which results in different ways of doing things, especially in educating the next generation. Philosophy of education developed by the West was shaped through philosophical thought, which manifested through an idea characterized by Materialism, Idealism, Secularism, and Rationalism. This philosophical thinking, however, affected the concept, interpretation and the definition of the knowledge itself. Rene Descartes, for instance, uses ratio as the sole criteria to measure the truth. Other western philosophers, such as John Locke, Immanuel Kant, Martin Heidegger, Emilio Betti, and Hans-Georg Gadammer, among others, also emphasize the use of ratio and the five senses as their source of knowledge, by which it creates a variety stream of philosophies and thoughts, such as empiricism, humanism, capitalism, existentialism, relativism, atheism, and many others that profoundly affect a number of disciplines, such as philosophy, science, sociology, psychology, politics, economics, and so on.

  14. The topology of the directed clique complex as a network invariant.

    Masulli, Paolo; Villa, Alessandro E P

    2016-01-01

    We introduce new algebro-topological invariants of directed networks, based on the topological construction of the directed clique complex. The shape of the underlying directed graph is encoded in a way that can be studied mathematically to obtain network invariants such as the Euler characteristic and the Betti numbers. Two different cases illustrate the application of the Euler characteristic. We investigate how the evolution of a Boolean recurrent artificial neural network is influenced by its topology in a dynamics involving pruning and strengthening of the connections, and to show that the topological features of the directed clique complex influence the dynamical evolution of the network. The second application considers the directed clique complex in a broader framework, to define an invariant of directed networks, the network degree invariant, which is constructed by computing the topological invariant on a sequence of sub-networks filtered by the minimum in- or out-degree of the nodes. The application of the Euler characteristic presented here can be extended to any directed network and provides a new method for the assessment of specific functional features associated with the network topology.

    In this work we review single step methods of the Runge–Kutta type with special properties. Among them are methods specially tuned to integrate problems that exhibit a pronounced oscillatory character and such problems arise often in celestial mechanics and quantum mechanics. Symplectic methods, exponentially and trigonometrically fitted methods, minimum phase-lag and phase-fitted methods are presented. These are Runge–Kutta, Runge–Kutta–Nyström and Partitioned Runge–Kutta methods. The theory of constructing such methods is given as well as several specific methods. In order to present the performance of the methods we have tested 58 methods from all categories. We consider the two dimensional harmonic oscillator, the two body problem, the pendulum problem and the orbital problem studied by Stiefel and Bettis. Also we have tested the methods on the computation of the eigenvalues of the one dimensional time independent Schrödinger equation with the harmonic oscillator, the doubly anharmonic oscillator and the exponential potentials.

  16. Quantum tunneling between Chern states in a Topological Insulator

    Liu, Minhao; Wang, Wudi; Richardella, Anthony R.; Kandala, Abhinav; Li, Jian; Yazdani, Ali; Samarth, Nitin; Ong, N. P.

    The tunneling of a macroscopic object through a barrier is a quintessentially quantum phenomenon important in field theory, low-temperature physics and quantum computing. Progress has been achieved in experiments on Josephson junctions, molecular magnets, and domain wall dynamics. However, a key feature - rapid expansion of the true vacuum triggered by a tunneling event is virtually unexplored. Here we report the detection of large jumps in the Hall resistance Ryx in a magnetized topological insulator which result from tunneling out of a metastable topological state. In the TI, the conducting electrons are confined to surface Dirac states. When magnetized, the TI enters the quantum anomalous Hall insulator state in which Ryx is strictly quantized. If the magnetic field is reversed, the sample is trapped in a metastable state. We find that, below 145 mK, Ryx exhibits abrupt jumps as large as one quantum unit on time-scales under 1 ms. If the temperature is raised, the escape rate is suppressed consistent with tunneling in the presence of dissipation. The jumps involve expansion of the thermodynamically stable state bubble over macroscopic lengths, but dissipation limits the final size. The results uncover novel effects of dissipation on macroscopic tunneling. We acknowledge support from DARPA SPAWAR (N66001-11-1-4110) and the Gordon and Betty Moore Foundations (GBMF4539).

  17. Internal hydriding in irradiated defected Zircaloy fuel rods: A review (LWBR Development Program)

    International Nuclear Information System (INIS)

    Although not a problem in recent commercial power reactors, including the Shippingport Light Water Breeder Reactor, internal hydriding of Zircaloy cladding was a persistent cause of gross cladding failures during the 1960s. It occurred in the fuel rods of water-cooled nuclear power reactors that had a small cladding defect. This report summarizes the experimental findings, causes, mechanisms, and methods of minimizing internal hydriding in defected Zircaloy-clad fuel rods. Irradiation test data on the different types of defected fuel rods, intentionally fabricated defected and in-pile operationally defected rods, are compared. Significant factors affecting internal hydriding in defected Zircaloy-clad fuel rods (defect hole size, internal and external sources of hydrogen, Zircaloy cladding surface properties, nickel alloy contamination of Zircaloy, the effect of heat flux and fluence) are discussed. Pertinent in-pile and out-of-pile test results from Bettis and other laboratories are used as a data base in constructing a qualitative model which explains hydrogen generation and distribution in Zircaloy cladding of defected water-cooled reactor fuel rods. Techniques for minimizing internal hydride failures in Zircaloy-clad fuel rods are evaluated

    2011-01-01

    In the first part of this thesis we study baryonic U(1) symmetries dual to Betti multiplets in the AdS_4/CFT_3 correspondence for M2 branes at Calabi-Yau 4-fold singularities. We begin by focusing on isolated toric singularities without vanishing 6-cycles, which we classify, and propose for them field theory duals. We then study in detail the cone over Q^111 and find agreement between the spectrum of baryonic operators in this theory and M5 branes wrapping 5-cycles in the Q^111 space. The physics of vacua in which these symmetries are spontaneously broken precisely matches a dual gravity analysis involving resolutions of the singularity, where we are able to match condensates, Goldstone bosons and global strings. We then study the implications of turning on a torsion 4-form flux. This flux non-trivially affects the supergravity dual of Higgsing, and we show that the supergravity and field theory analyses precisely match in an example based on Y^12(CP^2). We then explain how the choice of M-theory circle can r...

  20. Numerical Investigation of Capability of Self-Starting and Self-Rotating of a Vertical Axis Wind Turbine

    Tsai, Hsieh-Chen; Colonius, Tim

    2015-11-01

    The immersed boundary method is used to simulate the incompressible flow around two-dimensional airfoils at low Reynolds numbers in order to investigate the self-starting and self-rotating capability of a vertical axis wind turbine (VAWT) with NACA 0018 blades. By examining the torque generated by a three-bladed VAWT fixed at various orientations, a stable equilibrium and the optimal starting orientation that produces the largest torque have been observed. When Reynolds number is below a critical value, the VAWT oscillates around a stable equilibrium. However, the VAWT goes into continuous rotation from the optimal orientation when Reynolds number is above this critical value. It is also shown that VAWT with more blades is easier to self-start due to a wilder range of positive starting torques. Moreover, with a proper choice of load model, a VAWT is able to self-rotate and generate a designed averaged power. This project is supported by Caltech FLOWE center/Gordon and Betty Moore Foundation.

  2. Mean and turbulent flow development through an array of rotating elements

    2014-11-01

    The adjustment of an incoming boundary layer profile as it impacts and interacts with an array of elements has received significant attention in the context of terrestrial and aquatic canopies and more recently in the context of horizontal axis wind farms. The distance required for the mean flow profile to stabilize, the energy transport through the array, and the structure of the turbulence within the array are directly dependent upon such factors as the element height, density, rigidity/flexibility, frontal area distribution, element homogeneity, and underlying topography. In the present study, the mean and turbulent development of the flow through an array of rotating elements was examined experimentally. Element rotation has been shown to drastically alter wake dynamics of single and paired elements, but the possible extension of such rotation-driven dynamics had not previously been examined on larger groups of elements. Practically, such an array of rotating elements may provide insight into the flow dynamics of an array of vertical axis wind turbines. 2D particle image velocimetry was used along the length of the array in order to examine the effects of an increasing ratio of cylinder rotation speed to streamwise freestream velocity on flow development and structure.

    This volume of the LLE Review, covering October–December 2007, features “High-Intensity Laser–Plasma Interactions in the Refluxing Limit,” by P. M. Nilson, W. Theobald, J. Myatt, C. Stoeckl, M. Storm, O. V. Gotchev, J. D. Zuegel, R. Betti, D. D. Meyerhofer, and T. C. Sangster. In this article (p. 1), the authors report on target experiments using the Multi-Terawatt (MTW) Laser Facility to study isochoric heating of solid-density targets by fast electrons produced from intense, short-pulse laser irradiation. Electron refluxing occurs due to target-sheath field effects and contains most of the fast electrons within the target volume. This efficiently heats the solid-density plasma through collisions. X-ray spectroscopic measurements of absolute Kα (x-radiation) photon yields and variations of the Kβ/Kα b emission ratio both indicate that laser energy couples to fast electrons with a conversion efficiency of approximately 20%. Bulk electron temperatures of at least 200 eV are inferred for the smallest mass targets.

  5. Judaism in the theology of Sir Isaac Newton

    Goldish, Matt

    1998-01-01

    This book is based on my doctoral dissertation from the Hebrew University of Jerusalem (1996) of the same title. As a master's student, working on an entirely different project, I was well aware that many of Newton's theological manuscripts were located in our own Jewish National and University Library, but I was under the mistaken assumption that scores of highly qualified scholars must be assiduously scouring them and publishing their results. It never occurred to me to look at them at all until, having fmished my master's, I spoke to Professor David Katz at Tel-Aviv University about an idea I had for doctoral research. Professor Katz informed me that the project I had suggested was one which he himself had just fmished, but that I might be interested in working on the famous Newton manuscripts in the context of a project being organized by him, Richard Popkin, James Force, and the late Betty Jo Teeter Dobbs, to study and publish Newton's theological material. I asked him whether he was not sending me into ...

    Full Text Available An almost contact metric 3-submersion is a Riemannian submersion, π from an almost contact metric manifold (M4m+3,(φi,ξi,ηii=13,g onto an almost quaternionic manifold (N4n,(Jii=13,h which commutes with the structure tensors of type (1,1;i.e., π*φi=Jiπ*, for i=1,2,3. For various restrictions on ∇φi, (e.g., M is 3-Sasakian, we show corresponding limitations on the second fundamental form of the fibres and on the complete integrability of the horizontal distribution. Concommitantly, relations are derived between the Betti numbers of a compact total space and the base space. For instance, if M is 3-quasi-Saskian (dΦ=0, then b1(N≤b1(M. The respective φi-holomorphic sectional and bisectional curvature tensors are studied and several unexpected results are obtained. As an example, if X and Y are orthogonal horizontal vector fields on the 3-contact (a relatively weak structure total space of such a submersion, then the respective holomorphic bisectional curvatures satisfy: Bφi(X,Y=B′J′i(X*,Y*−2. Applications to the real differential geometry of Yarg-Milis field equations are indicated based on the fact that a principal SU(2-bundle over a compactified realized space-time can be given the structure of an almost contact metric 3-submersion.

    The Nuclear Energy - Knowledge base for Advanced Modeling and Simulation (NE-KAMS) is being developed at the Idaho National Laboratory in conjunction with Bettis Laboratory, Sandia National Laboratories, Argonne National Laboratory, Oak Ridge National Laboratory, Utah State University and others. The objective of this consortium is to establish a comprehensive knowledge base to provide Verification and Validation (V&V) and Uncertainty Quantification (UQ) and other resources for advanced modeling and simulation (M&S) in nuclear reactor design and analysis. NE-KAMS will become a valuable resource for the nuclear industry, the national laboratories, the U.S. NRC and the public to help ensure the safe operation of existing and future nuclear reactors. A survey and evaluation of the state-of-the-art of existing V&V and M&S databases, including the Department of Energy and commercial databases, has been performed to ensure that the NE-KAMS effort will not be duplicating existing resources and capabilities and to assess the scope of the effort required to develop and implement NE-KAMS. The survey and evaluation have indeed highlighted the unique set of value-added functionality and services that NE-KAMS will provide to its users. Additionally, the survey has helped develop a better understanding of the architecture and functionality of these data and knowledge bases that can be used to leverage the development of NE-KAMS.

  8. Analytic fields on compact balanced Hermitian manifolds

    Ganchev, G; Ganchev, George; Ivanov, Stefan

    1996-01-01

    On a Hermitian manifold we construct a symmetric $(1,1)$- tensor $H$ using the torsion and the curvature of the Chern connection. On a compact balanced Hermitian manifold we find necessary and sufficient conditions in terms of the tensor $H$ for a harmonic $1$-form to be analytic and for an analytic $1$-form to be harmonic. We prove that if $H$ is positive definite then the first Betti number $b_1 = 0$ and the Hodge number $h^{1,0} = 0$. We obtain an obstruction to the existence of Killing vector fields in terms of the Ricci tensor of the Chern connection: if the Chern form of the Chern connection on a compact balanced Hermitian manifold is non- positive definite then every Killing vector field is analytic; if moreover the Chern form is negative definite then there are no Killing vector fields. It is proved that on a compact balanced Hermitian manifold every affine with respect to the Chern connection vector field is an analytic vector field.

    International Nuclear Information System (INIS)

    The PDQ-8 program is designed to solve the neutron diffusion, depletion problem in one, two, or three dimensions on the CDC-6600 and CDC-7600 computers. The three dimensional spatial calculation may be either explicit or discontinuous trial function synthesis. Up to five lethargy groups are permitted. The fast group treatment may be simplified P(3), and the thermal neutrons may be represented by a single group or a pair of overlapping groups. Adjoint, fixed source, one iteration, additive fixed source, eigenvalue, and boundary value calculations may be performed. The HARMONY system is used for cross section variation and generalized depletion chain solutions. The depletion is a combination gross block depletion for all nuclides as well as a fine block depletion for a specified subset of the nuclides. The geometries available include rectangular, cylindrical, spherical, hexagonal, and a very general quadrilateral geometry with diagonal interfaces. All geometries allow variable mesh in all dimensions. Various control searches as well as temperature and xenon feedbacks are provided. The synthesis spatial solution time is dependent on the number of trial functions used and the number of gross blocks. The PDQ-8 program is used at Bettis on a production basis for solving diffusion--depletion problems. The report describes the various features of the program and then separately describes the input required to utilize these features

In addition, gender influences the creation of an environment that makes them unable to self-care, so that the field work that resulted in each of the members a comprehensive view on itself, which includes body, mind and spirit strengthen their mental health.

  13. Runge–Kutta type methods with special properties for the numerical integration of ordinary differential equations

    International Nuclear Information System (INIS)

    In this work we review single step methods of the Runge–Kutta type with special properties. Among them are methods specially tuned to integrate problems that exhibit a pronounced oscillatory character and such problems arise often in celestial mechanics and quantum mechanics. Symplectic methods, exponentially and trigonometrically fitted methods, minimum phase-lag and phase-fitted methods are presented. These are Runge–Kutta, Runge–Kutta–Nyström and Partitioned Runge–Kutta methods. The theory of constructing such methods is given as well as several specific methods. In order to present the performance of the methods we have tested 58 methods from all categories. We consider the two dimensional harmonic oscillator, the two body problem, the pendulum problem and the orbital problem studied by Stiefel and Bettis. Also we have tested the methods on the computation of the eigenvalues of the one dimensional time independent Schrödinger equation with the harmonic oscillator, the doubly anharmonic oscillator and the exponential potentials

    We use thermoeletric power (TEP), temperature- and field-dependent resistivity, and ultrahigh resolution, tunable, vacuum ultraviolet laser-based, angle-resolved photoemission spectroscopy (ARPES) measurements to study the electronic properties of WTe2, a compound that manifests exceptionally large, temperature-dependent magnetoresistance. The Fermi surface consists of two pairs of electron and two pairs of hole pockets along the X - Γ - X direction. We find a rare example of a temperature-induced Lifshitz transition at T ~ 160 K. Temperature dependent TEP shows a change of slope at T ~ 175 K and Kohler's rule was breakdown in the 70-140 K range. ARPES temperature scans confirm that the hole pockets completely disappear around 160 K. Our electronic structure calculations show a clear and substantial shift of the chemical potential μ (T) due to the semimetal nature of this material driven by modest changes in temperature.

  16. New two-dimensional response matrix iterative sweeping techniques

    International Nuclear Information System (INIS)

    Four closely related two-dimensional iterative sweeping techniques for solving response matrix equations have been developed and specifically applied to the within-group inner iteration strategy of the nodal transport option of the Argonne National Laboratory DIF3D production code. This option is used for multidimensional neutron transport calculations with a standard fission source outer/inner iteration strategy and fission source extrapolation (FSE) as a possible outer iteration acceleration technique. The inner iterations using a red/black (R/B) checkerborad strategy solve for the nodal surface quantities defined by response matrix equations. To counteract anomalous behavior in the fine-mesh limit, DP1 weights and positive ordinates are used to approximate the exponential integral functions. The new sweeping methods (specialized here for x-y geometry) employ a strategy similar to that used in the Bettis SN code TPT. For the new two-dimensional iterative techniques, this encompasses an upsweep/downsweep through the spatial mesh calculating the nodal surface quantities

    Significant progress in direct-drive inertial confinement fusion (ICF) research has been made since the completion of the 60-beam, 30-kJUV OMEGA Laser System [Boehly, Opt. Commun. 133, 495 (1997)] in 1995. A theory of ignition requirements, applicable to any ICF concept, has been developed. Detailed understanding of laser-plasma coupling, electron thermal transport, and hot-electron preheating has lead to the measurement of neutron-averaged areal densities of ˜200mg/cm2 in cryogenic target implosions. These correspond to an estimated peak fuel density in excess of 100g/cm3 and are in good agreement with hydrodynamic simulations. The implosions were performed using an 18-kJ drive pulse designed to put the converging fuel on an adiabat of two. The polar-drive concept will allow direct-drive-ignition research on the National Ignition Facility while it is configured for indirect drive. Advanced ICF ignition concepts—fast ignition [Tabak et al., Phys. Plasmas 1, 1626 (1994)] and shock ignition [Betti et al., Phys. Rev. Lett. 98, 155001 (2007)]—have the potential to significantly reduce ignition driver energies and/or provide higher target gain.

  18. Superconformal Symmetry in the Kaluza-Klein Spectrum of Warped AdS(3)

    2016-01-01

    We study the Kaluza-Klein spectrum of warped $AdS_3$ compactifications of type IIB with five-form flux which are dual to $\\mathcal{N}=(0,2)$ SCFTs in two dimensions. We prove that the spectra of fluctuations of both the spin 2 sector of the graviton and the axio-dilaton are bounded. At the bound the modes have the correct quantum numbers to be chiral primaries and descendants thereof respectively. Moreover, we prove that the same modes give rise to superpartners in the dilatino spectrum. Our results show that a subset of the mesonic chiral ring of the dual SCFT is isomorphic to the first Kohn-Rossi cohomology groups. As an example, we consider the compactification of four-dimensional $Y^{p,q}$ theories on Riemann surfaces for the case of the universal twist. We conclude by studying fluctuations of the three-form, where we are able to identify Betti multiplets after imposing some mild assumptions.

    2012-11-01

    We analyze the flow field within an array of 18 vertical-axis wind turbines (VAWTs) at full-scale and under natural wind conditions. The emphasis is on the energy flux into the turbine array and the energy extraction by the turbines. The wind velocities throughout the turbine array are measured using a portable meteorological tower with seven, vertically-staggered, three-component ultrasonic anemometers. These measurements yield a detailed insight into the turbine wakes and the recovery of the flow. A high planform kinetic energy flux is detected, which enables the flow velocities to return to 95% of the upwind value within six rotor diameters downwind from a turbine row. This is significantly faster than the recovery behind a typical horizontal-axis wind turbine (HAWT). The Presentation will compare the results for different rotor configurations. Conclusions will be drawn about the influence of these configurations on the power production of the individual turbines as well as the turbine array as a whole.

    2014-11-01

    The behavior of inverted flags has received recent attention in the study of the interaction of flexible bodies with fluid flows. It has implications in a variety of natural phenomena, such as the fluttering of leaves in the wind. As opposed to a conventional flag, defined by a fixed leading edge and a free trailing edge, an inverted flag has a free leading edge and a fixed trailing edge. The reversed flow orientation of inverted flags has led to a surprising observation. Over a narrow range of wind speeds, they exhibit a large-amplitude flapping motion that is not present in their conventional counterparts. Our study experimentally investigates the effects of flag morphology on the flapping behavior of inverted flags. Different flags ranging from rectangles to triangles are studied in a wind tunnel to assess the underlying parameters that govern their dynamics. We observe a significant shift in the limit-cycle flapping mode that is a function of flag shape parameters. This research is supported by the Lester Lees Aeronautics Summer Undergraduate Research Fellowship and the Gordon and Betty Moore Foundation.

  1. The role of tip deflection on the thrust produced by rigid flapping fins

    Huera-Huarte, Francisco; Gharib, Morteza

    2015-11-01

    It is well known that flexibility plays an important role in the propulsion performance and efficiency of oscillating fin based propulsion systems. Compliance is one of the aspects that has received more attention, as it seems to be a common feature in nature's flyers and swimmers. Active control strategies are also common in nature. We will show how by deflecting only the last 10% of length of a rigid fin, at the tip, the thrust can be changed dramatically. This can be thought as an alternative to passive flexibility for controlling very efficiently the momentum transfer in the wake and therefore the thrust generation when flapping. A series of experiments have been carried with a robotic fin that allowed the control of its flapping kinematics as well as the control of the motions of its tip independently. We will be showing situations in which the tip was kept at a certain fixed position during a power stroke, and others in which it moved either in-phase or out-of-phase with the fin. The observed thrust and wake dynamics will be discussed for all these situations.

  2. On the Brauer group

    International Nuclear Information System (INIS)

    For an arithmetic model X of a Fermat surface or a hyperkahler variety with Betti number b2(V otimes k-bar)>3 over a purely imaginary number field k, we prove the finiteness of the l-components of Br'(X) for all primes l>>0. This yields a variant of a conjecture of M. Artin. If V is a smooth projective irregular surface over a number field k and V(k)≠ nothing, then the l-primary component of Br(V)/Br(k) is an infinite group for every prime l. Let A1→M1 be the universal family of elliptic curves with a Jacobian structure of level N>=3 over a number field k supset of Q(e2πi/N). Assume that M1(k) ≠ nothing. If V is a smooth projective compactification of the surface A1, then the l-primary component of Br(V)/Br(M-bar1) is a finite group for each sufficiently large prime l

  3. Moment-angle complexes from simplicial posets

    2009-01-01

    We extend the construction of moment-angle complexes to simplicial posets by associating a certain T^m-space Z_S to an arbitrary simplicial poset S on m vertices. Face rings Z[S] of simplicial posets generalise those of simplicial complexes, but have much more complicated algebraic structure. Our primary motivation is to study the face rings Z[S] by topological methods. The space Z_S has many important topological properties of the original moment-angle complex Z_K associated to a simplicial complex K. In particular, we prove that the integral cohomology algebra of Z_S is isomorphic to the Tor-algebra of the face ring Z[S]. This leads directly to a generalisation of Hochster's theorem, expressing the algebraic Betti numbers of the ring Z[S] in terms of the homology of full subposets in S. Finally, we estimate the total amount of homology of Z_S from below by proving the toral rank conjecture for the moment-angle complexes Z_S.

    2012-12-01

    There are many barriers to data management and sharing among earth and environmental scientists; among the most significant are lacks of knowledge about best practices for data management, metadata standards, or appropriate data repositories for archiving and sharing data. We have developed an open-source add-in for Excel and an open source web application intended to help researchers overcome these barriers. DataUp helps scientists to (1) determine whether their file is CSV compatible, (2) generate metadata in a standard format, (3) retrieve an identifier to facilitate data citation, and (4) deposit their data into a repository. The researcher does not need a prior relationship with a data repository to use DataUp; the newly implemented ONEShare repository, a DataONE member node, is available for any researcher to archive and share their data. By meeting researchers where they already work, in spreadsheets, DataUp becomes part of the researcher's workflow and data management and sharing becomes easier. Future enhancement of DataUp will rely on members of the community adopting and adapting the DataUp tools to meet their unique needs, including connecting to analytical tools, adding new metadata schema, and expanding the list of connected data repositories. DataUp is a collaborative project between Microsoft Research Connections, the University of California's California Digital Library, the Gordon and Betty Moore Foundation, and DataONE.

    Microwave Kinetic Inductance Detectors (MKIDs) are superconducting resonators useful for detecting light from the millimeter-wave to the X-ray. These detectors are easily multiplexed, as the resonances can be tuned to slightly different frequencies, allowing hundreds of detectors to be read out simultaneously using a single feedline. The Multicolor Submillimeter Inductance Camera, MUSIC, will use 2304 antenna-coupled MKIDs in multicolor operation, with bands centered at wavelengths of 0.85, 1.1, 1.3 and 2.0 mm, beginning in 2011. Here we present the results of our demonstration instrument, DemoCam, containing a single 3-color array with 72 detectors and optics similar to MUSIC. We present sensitivities achieved at the telescope, and compare to those expected based upon laboratory tests. We explore the factors that limit the sensitivity, in particular electronics noise, antenna efficiency, and excess loading. We discuss mitigation of these factors, and how we plan to improve sensitivity to the level of background-limited performance for the scientific operation of MUSIC. Finally, we note the expected mapping speed and contributions of MUSIC to astrophysics, and in particular to the study of submillimeter galaxies. This research has been funded by grants from the National Science Foundation, the Gordon and Betty Moore Foundation, and the NASA Graduate Student Researchers Program.

A patient registry is a tool that documents the natural history of target diseases. Clinicians and researchers use registries to monitor patient comorbidities, care procedures and processes, and treatment effectiveness for the purpose of improving care quality. Enactments of the Affordable Care Act 2010 and the Mental Health Parity and Addiction Equity Act 2008 open opportunities for many substance users to receive treatment services in general medical settings. An increased number of patients with a wide spectrum of SUD will initially receive services with a chronic disease management approach in primary care. The establishment of computer-based SUD patient registries can be assisted by wide adoption of electronic health record systems. The linkage of SUD patient registries with electronic health record systems can facilitate the advancement of SUD treatment research efforts and improve patient care.

    In Brazil, where cultivated pastures constitute the dominant land use form, cattle ranching intensification plays a major role towards more environmentally sustainable agricultural practices, through its potential for mitigating GHG emissions, as well as by making available cost-effective land reserve for other uses. However, environmentally sustainable livestock intensification, one of the key goals pursued by Plano ABC (the federal government low carbon agriculture plan), strongly depends on our ability to more precisely identify pasture conditions, improvement needs, and the respective cattle support capacities. To this end, and with the support of the Gordon and Betty Moore Foundation, we have concentrated efforts in order to have: 1) a more detailed and updated map of the brazilian pasturelands; 2) a thorough biophysical differentiation of these pastures according to degradation stages / forage levels; and 3) an estimation of overall pasture productivity trends. Our initial estimates, based on the interpretation of satellite and census data, suggest that as much as 50% of the total grazing area in Brazil (about 170 Mhectares) are moderately or severely affected by soil-plant degradation. On the other hand, our preliminary results also corroborate the enormous potential of well managed pastures to positively impact carbon and water fluxes. Based on satellite data and pasture samples from large and productive cattle ranch operations in the central savanna biome in Brazil (Cerrado), we estimated total growing season (October to April) biomass and evapotranspiration to correspond to 9 Gt of carbon and 420 Gt of water, respectively.

  8. Chemical and spectrochemical production analysis of ThO2 and 233UO2-ThO2 pellets for the light water breeder reactor core for Shippingport (LWBR development program)

    International Nuclear Information System (INIS)

    The Bettis Atomic Power Laboratory has utilized wet chemical, emission spectrochemical, and mass spectrometric analytical techniques for the production analysis of the ThO2 and 233UO2-ThO2 (1 to 6 wt percent 233UO2) pellets for the Light Water Breeder Reactor (LWBR) core for Shippingport. Proof of the fuel breeding concept necessitates measurement of precise and accurate chemical characterization of all fuel pellets before core life. Chemistry's efforts toward this goal are presented in three main sections: (1) general discussions relating the chemical requirements for ThO2 and 233UO2-ThO2 core materials to the analytical capabilities, (2) technical discussions of the chemical and instrumental technology applied for the analysis of aluminum, boron, calcium, carbon, chloride plus bromide, chromium, cobalt, copper, dysprosium, europium, fluoride, gadolinium, iron, magnesium, manganese, mercury, molybdenum, nickel, nitrogen, samarium, silicon, titanium, vanadium, thorium, and uranium (total, trace, and uranium VI), and (3) a formal presentation of the analytical procedures as applied to the LWBR Development Program.

    Let X be a Zariski open subset of a compact Kaehler manifold. In this paper, we study the set $\\Sigma^k(X)$ of one dimensional local systems on X with nonvanishing kth cohomology. We show that under certain conditions ( X compact, X has a smooth compactification with trivial first Betti number, or k=1) $\\Sigma^k(X)$ is a union of translates of sets of the form $f^*H^1(T, C^*)$, where $f:X \\to T$ is a holomorphic map to a complex Lie group which is an extension of a compact complex torus by a product of C^*'s (these correspond to semiabelian varieties in the algebraic category). This generalizes earlier work of Beauville, Green, Lazarsfeld, Simpson and the author in the compact case. The main novelty lies in the proofs which involve consideration of Higgs fields with logarithmic poles. While a completely satifactory theory of such objects is still lacking, we are able to work out what we need in the rank one case by borrowing ideas from mixed Hodge theory. This will appear in the Journal of Algebraic Geometry.

    Theoretical work has shown that a low energy spike pulse in front of the drive laser pulse can help mitigate the growth of hydrodynamic instabilities in targets for inertial confinement fusion.[1]^ While other experiments [2] used higher spike pulse energies, this study reports the influence of a lower energy spike and longer spike-main pulse delay on the acceleration of planar CH targets. Time evolution of preimposed sinusoidal ripples on the target surface was observed using a monochromatic x-ray imaging system. Delayed onset and/or suppression of mode growth was found for the spike prepulse shots compared to those with a low intensity foot, in good agreement with predictions from FAST2D simulations. The propagation velocity of the decaying shock wave from the spike pulse was measured with VISAR and was also in good agreement with an analytical prediction.[3] [1] Metzler et al., Phys.

Sharing of patient health records among care providers is essential to realize the benefits of electronic health records. Health information exchange through meaningful use of electronic health records can improve health care safety, quality, and efficiency. Implementation of electronic health records and health information exchange presents great opportunities for health care integration, but also makes patient privacy potentially vulnerable. Privacy issues are paramount for patients with substance use problems. This paper discusses major differences between two federal privacy laws associated with health care for substance use disorders, identifies health care problems created by privacy policies, and describes potential solutions to these problems through technology innovation and policy improvement.Keywords: substance abuse, patient privacy, electronic health records, health information exchange

  12. Constrained maximum likelihood modal parameter identification applied to structural dynamics

    2016-05-01

    A new modal parameter estimation method to directly establish modal models of structural dynamic systems satisfying two physically motivated constraints will be presented. The constraints imposed in the identified modal model are the reciprocity of the frequency response functions (FRFs) and the estimation of normal (real) modes. The motivation behind the first constraint (i.e. reciprocity) comes from the fact that modal analysis theory shows that the FRF matrix and therefore the residue matrices are symmetric for non-gyroscopic, non-circulatory, and passive mechanical systems. In other words, such types of systems are expected to obey Maxwell-Betti's reciprocity principle. The second constraint (i.e. real mode shapes) is motivated by the fact that analytical models of structures are assumed to either be undamped or proportional damped. Therefore, normal (real) modes are needed for comparison with these analytical models. The work done in this paper is a further development of a recently introduced modal parameter identification method called ML-MM that enables us to establish modal model that satisfies such motivated constraints. The proposed constrained ML-MM method is applied to two real experimental datasets measured on fully trimmed cars. This type of data is still considered as a significant challenge in modal analysis. The results clearly demonstrate the applicability of the method to real structures with significant non-proportional damping and high modal densities.

    A record fuel hot-spot pressure P_{hs}=56±7  Gbar was inferred from x-ray and nuclear diagnostics for direct-drive inertial confinement fusion cryogenic, layered deuterium-tritium implosions on the 60-beam, 30-kJ, 351-nm OMEGA Laser System. 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, 011201(R) (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. PMID:27447511

    Dunne, Reeve; McKeon, Beverley

    2013-11-01

    The flow over a pitching and surging NACA 0018 airfoil at a chord Reynolds number of 100,000 is investigated using 2D time resolved particle image velocimetry. Sinusoidal pitch experiments between +/-30° at a reduced frequency k =Ωc/2U∞ = . 12 closely simulate the unsteady angle of attack experienced by the blade of a representative commercial vertical axis wind turbine (VAWT). The unsteady separation process is analyzed in detail with a focus on development of vorticity at the leading edge. Reduced order modeling techniques are used to deconstruct the flow and identify the evolution of dominant flow structures over the pitching cycle. Surging at the same reduced frequency and Umax/-Umin Umean = . 80 is added to investigate the effect of the Reynolds number variation associated with the rotation of a VAWT blade in a non-rotating, laboratory frame. This research is funded by the Gordon and Betty Moore Foundation through Grant GBMF #2645 to the California Institute of Technology.

    2014-11-01

    We present experimental results from three different full scale arrays of vertical-axis wind turbines (VAWTs) under natural wind conditions. One array consists of a row of four single turbines while the other two are made up of nine counter rotating turbine pairs. The wind velocities throughout the turbine arrays are measured using a portable meteorological tower with seven, vertically-staggered, three-component ultrasonic anemometers. Furthermore, the power output of each turbine is measured simultaneously with the free stream wind velocity and direction. These measurements yield detailed understanding of the aerodynamics inside the VAWT arrays and the resulting power productions. Quadrant hole analysis is employed to gain a better understanding of the vertical energy transport at the top of the VAWT array. Results comparing the energy transport and the responsible mechanisms between the larger turbine arrays and the four single turbines configuration will be presented. Furthermore, results are compared to the flow in urban and plant canopies. Emphasis is given to the flow physics in the adjustment region of the canopy, i.e. the region where the flow transitions from an atmospheric surface layer to a canopy flow. This project is funded by the Gordon and Betty Moore Foundation through Grant 2645.

    The immersed boundary method is used to simulate the incompressible flow around two-dimensional airfoils at sub-scale Reynolds number in order to investigate the self-starting capability of a vertical-axis wind turbine (VAWT). By investigating a single blade fixed at various angle of attacks, the leading edge vortex (LEV) is shown to play an important role in the starting mechanism for both flat-plate and NACA 0018 blades. Depending on the angle of attack of the blade, as the LEV grows, the corresponding low pressure region results in a thrust in the tangential direction, which produces a positive torque to VAWT. Due to the characteristics of the blades, a NACA 0018 blade produces a larger thrust over a wider range of angle of attacks than a flat-plate blade. Therefore, a VAWT with NACA 0018 blades can self-start more easily than one with flat-plate blades. Moreover, by investigating the starting torque of three-bladed VAWTs fixed at various orientations, the optimal orientation that produces the largest torque to start both VAWTs is with a blade parallel to the flow and facing downstream. The simulations are also compared to results from companion water-tunnel experiments at Caltech. This project is supported by Caltech FLOWE center/Gordon and Betty Moore Foundation.

The wind velocities throughout the turbine array are measured using a portable meteorological tower with seven, vertically-staggered, three-component ultrasonic anemometers. These measurements yield detailed insight into the turbine wakes and the recovery of the flow velocity behind the turbines. Quadrant hole analysis is employed to gain a better understanding of the energy transport at the top and the bottom of the VAWT array. The results are compared to the flow in horizontal-axis wind farms as well as urban and plant canopies. Emphasis is given to the flow physics in the adjustment region of the canopy, i.e. the region where the flow transitions from an atmospheric boundary layer to a canopy flow.

    2012-11-01

    A NACA 0018 airfoil is pitched about the leading edge over a large angle of attack range (+/- ~40°) at a chord Reynolds number of 110,000 to simulate the flow over a single blade in a vertical axis wind turbine (VAWT). Particle image velocimetry (PIV) measurements are made to investigate the effects of pitching on leading edge vortex (LEV) development and separation. Time resolved experiments are performed to track vortex formation and convection over the airfoil for sinusoidal pitching motions corresponding to a VAWT trajectory as well as impulsive pitch up and pitch down motions. These results are compared to the wake of steady, post stall, high angle of attack airfoils (α =20° -30°). The characteristics of the leading edge vortex development and subsequent separation from the airfoil are discussed, with a view to characterizing its effect on power generation with VAWTs and future flow control strategies for turbine performance improvement. Funding from the Gordon and Betty Moore Foundation is gratefully acknowledged.

  19. Coriolis effect on dynamic stall in a vertical axis wind turbine

    Tsai, Hsieh-Chen; Colonius, Tim

    2013-11-01

    The immersed boundary method is used to simulate the flow around a two-dimensional rotating NACA 0018 airfoil at moderate (sub-scale) Reynolds number in order to investigate separated flow occurring on a vertical-axis wind turbine (VAWT). The influence of dynamic stall on the forces is characterized as a function of tip-speed ratio. The influence of the Coriolis effect is also investigated by comparing the rotating airfoil to one undergoing a surging and pitching motion that produces an equivalent speed and angle-of-attack variation over the cycle. While the Coriolis force produces only small differences in the averaged forces, it plays an important role during dynamic stall. Due to the fact that the Coriolis force deflects the fluid and propagates the vortices differently, the wake-capturing phenomenon of the trailing edge vortex is observed in the flow around the rotating airfoil during a certain range of azimuthal angle. This wake-capturing of the trailing edge vortex leads to a large decrease in lift. However, because of the phase difference between each wake-capturing, there are only small differences in the average forces. The simulations are also compared to results from companion water-tunnel experiments at Caltech. This project is supported by the Gordon and Betty Moore Foundation.

  20. Vortex shedding from vertical axis wind turbine blades under linear motion

    Dunne, Reeve; McKeon, Beverley

    2014-11-01

    A NACA 0018 airfoil was pitched and surged sinusoidally in in a mean free stream flow at Rec = 100 , 000 to simulate the flow over vertical axis wind turbine (VAWT) blades. Angle of attack variations between α = +/-30° and velocity variation of Umax/-Umin Umean = . 80 at a reduced frequency k =Ωc/2U∞ = . 12 result in strong dynamic stall on the blade. Multiple flow regimes occur during the airfoil motion resulting in vortex shedding over a large range of frequencies. A model of the phase averaged (based on airfoil angle of attack and velocity) flow developed using dynamic mode decomposition highlights the evolution of the leading edge or dynamic stall vortex at the airfoil frequency. Instantaneous results show vortex shedding at frequencies up to 100 times higher than the frequency of the pitch/surge motion and smeared out by the phase averaging process. The implications for forcing on the blade (and associated wind turbine) are described. This research is funded by the Gordon and Betty Moore Foundation through Grant GBMF #2645 to the California Institute of Technology.

    Recent studies have indicated that arrays of vertical axis wind turbines (VAWTs) could potentially harvest significantly more power per unit land area than arrays composed of conventional horizontal axis wind turbines. However, to design VAWT arrays for optimal power conversion, a more comprehensive understanding of inter-turbine energy transfer is needed. In the presented study, a geometrically scaled array of rotating circular cylinders is used to model a VAWT array. The horizontal inter-cylinder mean fluid velocities and Reynolds stresses are measured on several cross-sections using 2D particle image velocimetry in a flume. Two orientations of the array relative to the incoming flow are tested. The results indicate that cylinder rotation drives asymmetric mean flow patterns within and above the array, resulting in non-uniform distributions of turbulent kinetic energy. The variability is observed to be directly related to the ratio of the cylinder rotation speed to the streamwise water velocity. Emphasis is placed on the implications of the asymmetries for power production.

    James N. Kile, of Needham Heights, Massachusetts, died on 17 August 2007, following a brave two-year battle with cancer. One of three children of David R. Kile and Betty Jane Kile, Jim was born in Niagara Falls, New York, on 20 April 1958 and lived in the nearby village of Lewiston before his family settled in Alden, an hour east of Niagara Falls, when Jim was nine. Jim's father worked for American Telephone and Telegraph for 37 years, and his mother was a homemaker. Jim earned his Bachelor's degree in Physics from Rensselaer Polytechnic Institute in 1980, a Master's degree from Northwestern University in 1982, and a Doctorate from Tufts University in 1996 under the direction of Robert Willson. His thesis involved comparison of radio data from the Very Large Array and the Russian RATAN 600 telescope with Yohkoh soft X-ray data, with an emphasis on understanding the relationship between solar noise storms and coronal magnetic fields. While working on his thesis, Jim collaborated with one of us (EWC) at the Air Force Research Laboratory on an investigation of the 154-day periodicity in solar flares. The resulting publication (ApJ 370, 442, 1991) is his most cited work. Jim co-authored four other papers in refereed journals. Jim's professional affiliations included the American Astronomical Society, the American Institute of Aeronautics and Astronautics, the American Geophysical Union, and the Astronomical Society of the Pacific. Jim worked as a contractor in the defense industry from 1982 until the time of his death, settling in the Boston area in the early 1980s. He worked for Calspan Corporation from 1982-1989, the Ultra Corporation from 1989-1994, and the Riverside Research Institute from 1994-2007. He was a highly-respected expert in radar systems, including radar data and systems analysis, systems engineering, and planning support for radar acquisition programs and technology development. The work entailed frequent extended travel to Norway for system testing

  3. Hidden landscapes in thin film topological insulators: between order and disorder, 2D and 3D, normal and topological phases

    Science.gov (United States)

    Oh, Seongshik

    Topological insulator (TI) is one of the rare systems in the history of condensed matter physics that is initiated by theories and followed by experiments. Although this theory-driven advance helped move the field quite fast despite its short history, apparently there exist significant gaps between theories and experiments. Many of these discrepancies originate from the very fact that the worlds readily accessible to theories are often far from the real worlds that are available in experiments. For example, the very paradigm of topological protection of the surface states on Z2 TIs such as Bi2Se3, Bi2Te3, Sb2Te3, etc, is in fact valid only if the sample size is infinite and the crystal momentum is well-defined in all three dimensions. On the other hand, many widely studied forms of TIs such as thin films and nano-wires have significant confinement in one or more of the dimensions with varying level of disorders. In other words, many of the real world topological systems have some important parameters that are not readily captured by theories, and thus it is often questionable how far the topological theories are valid to real systems. Interestingly, it turns out that this very uncertainty of the theories provides additional control knobs that allow us to explore hidden topological territories. In this talk, I will discuss how these additional knobs in thin film topological insulators reveal surprising, at times beautiful, landscapes at the boundaries between order and disorder, 2D and 3D, normal and topological phases.

  4. Operator algebras and topology

    International Nuclear Information System (INIS)

    These notes, based on three lectures on operator algebras and topology at the 'School on High Dimensional Manifold Theory' at the ICTP in Trieste, introduce a new set of tools to high dimensional manifold theory, namely techniques coming from the theory of operator algebras, in particular C*-algebras. These are extensively studied in their own right. We will focus on the basic definitions and properties, and on their relevance to the geometry and topology of manifolds. A central pillar of work in the theory of C*-algebras is the Baum-Connes conjecture. This is an isomorphism conjecture, as discussed in the talks of Luck, but with a certain special flavor. Nevertheless, it has important direct applications to the topology of manifolds, it implies e.g. the Novikov conjecture. In the first chapter, the Baum-Connes conjecture will be explained and put into our context. Another application of the Baum-Connes conjecture is to the positive scalar curvature question. This will be discussed by Stephan Stolz. It implies the so-called 'stable Gromov-Lawson-Rosenberg conjecture'. The unstable version of this conjecture said that, given a closed spin manifold M, a certain obstruction, living in a certain (topological) K-theory group, vanishes if and only M admits a Riemannian metric with positive scalar curvature. It turns out that this is wrong, and counterexamples will be presented in the second chapter. The third chapter introduces another set of invariants, also using operator algebra techniques, namely L2-cohomology, L2-Betti numbers and other L2-invariants. These invariants, their basic properties, and the central questions about them, are introduced in the third chapter. (author)

    The OSDT Android SensorPod is a custom-designed mobile computing platform for assembling wireless sensor networks for environmental monitoring applications. Funded by an award from the Gordon and Betty Moore Foundation, the OSDT SensorPod represents a significant technological advance in the application of mobile and cloud computing technologies to near-real-time applications in environmental science, natural resources management, and disaster response and recovery. It provides a modular architecture based on open standards and open-source software that allows system developers to align their projects with industry best practices and technology trends, while avoiding commercial vendor lock-in to expensive proprietary software and hardware systems. The integration of mobile and cloud-computing infrastructure represents a disruptive technology in the field of environmental science, since basic assumptions about technology requirements are now open to revision, e.g., the roles of special purpose data loggers and dedicated site infrastructure. The OSDT Android SensorPod was designed with these considerations in mind, and the resulting system exhibits the following characteristics - it is flexible, efficient and robust. The system was developed and tested in the three science applications: 1) a fresh water limnology deployment in Wisconsin, 2) a near coastal marine science deployment at the UCSD Scripps Pier, and 3) a terrestrial ecological deployment in the mountains of Taiwan. As part of a public education and outreach effort, a Facebook page with daily ocean pH measurements from the UCSD Scripps pier was developed. Wireless sensor networks and the virtualization of data and network services is the future of environmental science infrastructure. The OSDT Android SensorPod was designed and developed to harness these new technology developments for environmental monitoring applications.

  6. Mechanistic modeling of Zircaloy deformation and fracture in fuel element analysis

    Nichols, F.A.

    1985-06-01

    A review is given of the comprehensive model developed in the 1960's at the Bettis Atomic Power Laboratory to explain the creep of Zircaloy during neutron irradiation and applied to fuel element analysis and design. The in-pile softening observed at low stresses was hypothesized to be due to a combination of the growth-directed Roberts-Cottrell yielding creep originally proposed for ..cap alpha..-uranium and the formation of point defect loops preferentially on certain planes in response to the applied stress, with the second process being of relatively greater importance. The in-pile hardening observed at high stresses (or strain-rates) was proposed to be due to the cutting by dislocations of radiation-produced obstacles. In this stress (strain-rate) region, in-pile behavior was proposed to be identical to post-irradiation behavior. At intermediate stresses (strain-rates) a mechanism of radiation-enhanced climb around obstacles was suggested as being rate controlling. As the stress is decreased, the climb process becomes easier and the rate was then predicted to be controlled by glide at a flow stress characteristic of unirradiated, annealed material, where radiation-enhanced diffusion enabled climbing around the normal strain-hardening obstacles. At still lower stresses, this glide process became negligibly slow compared with the growth-connected creep mechanism which was presumed to operate independently. The overall scheme was shown to be good agreement with all the in-pile data then available and implemented into the computer analysis of fuel element behavior. 48 refs., 1 fig.

  7. Stress corrosion cracking growth rate of TT alloy 690 and its weld joint in simulated PWR primary water

    International Nuclear Information System (INIS)

    Recently, some researchers reported that the SCC growth rate (SCCGR) of cold worked thermally treated (TT) Alloy 690 was significantly different in heat by heat. But, author has hypothesized that these high SCCGRs in cold worked TT Alloy 690 could be due to the metallurgical characteristics of these heats. In order to confirm this hypothesis, this study has been started in the author's laboratory, and the following 4 new evidences were obtained. First, microcracks of carbides and voids were observed in eutectic M23C6 GB carbides (primary carbides) for cold rolled laboratory heat after as cast or lightly forged condition or for chemical composition simulated Bettis'TT Alloy 690 heat, after cold rolling, before SCC test. However, microcracks in primary carbides along grain boundaries and voids were rarely detected in the cold rolled commercial heat of TT Alloy 690 used for CRDM penetrations. Secondly, the SCCGR observed in TT Alloy 690 was different in each hot working process and each heat. Comparing the SCCGRs for all heats of cold worked TT Alloy 690, the SCCGR decreased with increasing of Vickers hardness. However, in same heats of cold worked TT Alloy 690, the SCCGR increased with increasing of Vickers hardness. Thirdly, the SCCGR in cold rolled TT Alloy 690 should be integrated by the effect of hardness or cold working ratio and by the effect of existing ratio of primary M23C6 carbides with cracks and Voids due to chemical composition and the fabrication process of TT Alloy 690. Fourthly, it is argued that the high SCCGRs in highly cold rolled TT Alloy 690 are not representative of the practical situation with TT Alloy 690 in service for CRDM adapter nozzles etc. The high SCCGR of highly cold rolled TT Alloy 690 is not thought to be an accurate tool in predicting the possibility of cracking of TT Alloy 690 for CRDM adapter nozzles.

    We present DisPerSE, a novel approach to the coherent multiscale identification of all types of astrophysical structures, in particular the filaments, in the large-scale distribution of the matter in the Universe. This method and the corresponding piece of software allows for a genuinely scale-free and parameter-free identification of the voids, walls, filaments, clusters and their configuration within the cosmic web, directly from the discrete distribution of particles in N-body simulations or galaxies in sparse observational catalogues. To achieve that goal, the method works directly over the Delaunay tessellation of the discrete sample and uses the Delaunay tessellation field estimator density computed at each tracer particle; no further sampling, smoothing or processing of the density field is required. The idea is based on recent advances in distinct subdomains of the computational topology, namely the discrete Morse theory which allows for a rigorous application of topological principles to astrophysical data sets, and the theory of persistence, which allows us to consistently account for the intrinsic uncertainty and Poisson noise within data sets. Practically, the user can define a given persistence level in terms of robustness with respect to noise (defined as a 'number of σ') and the algorithm returns the structures with the corresponding significance as sets of critical points, lines, surfaces and volumes corresponding to the clusters, filaments, walls and voids - filaments, connected at cluster nodes, crawling along the edges of walls bounding the voids. From a geometrical point of view, the method is also interesting as it allows for a robust quantification of the topological properties of a discrete distribution in terms of Betti numbers or Euler characteristics, without having to resort to smoothing or having to define a particular scale. In this paper, we introduce the necessary mathematical background and describe the method and implementation

    The development of earthquake early warning capabilities in the United States is now accelerating and expanding as the technical capability to provide warning is demonstrated and additional funding resources are making it possible to expand the current testing region to the entire west coast (California, Oregon and Washington). Over the course of the next two years we plan to build a prototype system that will provide a blueprint for a full public system in the US. California currently has a demonstrations warning system, ShakeAlert, that provides alerts to a group of test users from the public and private sector. These include biotech companies, technology companies, the entertainment industry, the transportation sector, and the emergency planning and response community. Most groups are currently in an evaluation mode, receiving the alerts and developing protocols for future response. The Bay Area Rapid Transit (BART) system is the one group who has now implemented an automated response to the warning system. BART now stops trains when an earthquake of sufficient size is detected. Research and development also continues to develop improved early warning algorithms to better predict the distribution of shaking in large earthquakes when the finiteness of the source becomes important. The algorithms under development include the use of both seismic and GPS instrumentation and integration with existing point source algorithms. At the same time, initial testing and development of algorithms in and for the Pacific Northwest is underway. In this presentation we will review the current status of the systems, highlight the new research developments, and lay out a pathway to a full public system for the US west coast. The research and development described is ongoing at Caltech, UC Berkeley, University of Washington, ETH Zurich, Southern California Earthquake Center, and the US Geological Survey, and is funded by the Gordon and Betty Moore Foundation and the US Geological

  10. DNBR analyses under steady-state and accident conditions for a double-flat-core high conversion light water reactor

    International Nuclear Information System (INIS)

    A double-flat-core high conversion light water reactor (HCLWR-JDF1) has been developed at JAERI aiming at better fuel utilization and higher safety margin. The HCLWR has two pancake type cores piled up with lower, internal and upper axial blankets. Fuel rods are arranged in a triangular lattice with p/d = 1.23. The lengths of each core part and each blanket part are 60 cm and 30 cm, respectively. Departure from nucleate boiling (DNB) analyses were performed under steady-state operational condition and accident conditions. The primary coolant pump trip accident and locked rotor accident were selected for the transient analyses. The primary system transient calculations under accident conditions were performed with a best-estimate code J-TRAC using the same conservative assumptions as in the licensing calculation for a current LWR. The KfK critical heat flux (CHF) correlation coupled with the COBRA-IV-I subchannel analysis was used to evaluate the DNB ratio (DNBR). The KfK correlation was verified with the data from small scale (4 and 7 rods) CHF experiments at JAERI and 20-rods CHF experiments at Bettis Atomic Power Laboratory. The mixing coefficient and grid spacer loss coefficient used in the subchannel analyses were experimentally determined. Based on the criterion that no fuel rod in the core experiences DNB with 95 % probability at 95 % confidence level, which is used in the current LWR licensing procedure, the minimum DNBR was determined to be 1.28 with the KfK correlation. The estimated minimum DNBR's were 1.66 for the steady-state condition, 1.56 for the pump trip accident and 1.34 for the locked rotor accident. These minimum DNBR's are larger than the minimum allowable DNBR limit. The results indicate that the present HCLWR design is acceptable from a view point of the DNBR criterion. (author)

  11. The history of breast cancer advocacy.

    There have been four key steps in the advent of breast cancer advocacy: priming the market, engaging consumers, establishing political advocacy, and taking the advocacy mainstream. Breast cancer was surrounded by secrecy until the 1980s, when brave individuals such as former First Ladies Betty Ford and Nancy Reagan, and founder of the Susan G. Komen Foundation, Nancy Brinker (Susan Komen's sister), began speaking publicly about the personal impact of the disease, which increased awareness of breast cancer and made it more acceptable to talk about it openly. At the same time, statistics about breast cancer were presented in new ways that the public could understand. Public health advocates played a key role in the second step, engaging consumers, when they established guidelines in the 1980s that encouraged women to perform breast self-examinations (BSEs) and have screening mammograms and clinical breast examinations (CBEs). Other events that helped engage consumers were increased media coverage of breast cancer issues, the founding of the Komen Race for the Cure in 1983, and the establishment of other programs that both educated the public and raised funds. Funds from these efforts enabled advocates to hold educational forums and produce educational materials in different media and tailored to different audiences and to become active in the funding of research. The third step, political action, became possible when breast cancer advocates joined together in the 1980s and 1990s to work toward legislative, regulatory, and funding changes, such as passage of the Mammography Quality Standards Act and increased funding for the National Cancer Institute. These efforts contributed to a more than quadrupling of federal funding for breast cancer research in the 1990s. Going mainstream, the final step in the advocacy process, entailed establishing a solid base of support to ensure that the message about breast cancer stays strong and fresh. This has been achieved by engaging

Research data suggest that the majority of individuals with a substance use disorder either do not use treatment or delay treatment-seeking for over a decade. The separation of substance abuse services from mainstream medical care and a lack of preventive services for substance abuse in primary care can contribute to under-detection of substance use problems. When fully enacted in 2014, the Patient Protection and Affordable Care Act 2010 will address these barriers by supporting preventive services for substance abuse (screening, counseling and integration of substance abuse care with primary care. One key factor that can help to achieve this goal is to incorporate the standardized screeners or common data elements for substance use and related disorders into the electronic health records (EHR system in the health care setting. Incentives for care providers to adopt an EHR system for meaningful use are part of the Health Information Technology for Economic and Clinical Health Act 2009. This commentary focuses on recent evidence about routine screening and intervention for alcohol/drug use and related disorders in primary care. Federal efforts in developing common data elements for use as screeners for substance use and related disorders are described. A pressing need for empirical data on screening, brief intervention, and referral to treatment (SBIRT for drug-related disorders to inform SBIRT and related EHR efforts is highlighted

  13. PACER-IBM: A two dimensional Monte Carlo multigroup program for the IBM personal computer

    International Nuclear Information System (INIS)

    PACER-IBM is a Monte Carlo computer program written in BASIC at Bettis for the IBM personal computer. This program is capable of solving simple two dimensional neutron transport problems in X - Y geometry. The space - energy neutron flux distribution over the energy range of 10 MeV to 0 eV is calculated using fixed source starts within the source regions of the solution geometry. PACER-IBM accesses multigroup cross sections which have been prepared using the CDC-7600 program RCPL1, a program to prepare neutron and photon cross section libraries for RCP01, and down loaded from the CDC-7600. Neutron behavior in the PC program is simulated by a random walk, a process that is identical to that used in the CDC-7600 Monte Carlo program PACER. A neutron's location in phase space, i.e.., its position, direction, and energy is selected randomly and the neutron is tracked through the solution geometry (in free flight) until a collision occurs. In the collision analysis new neutron direction and energy are selected randomly based upon probabilities determined from basic neutron cross section data. The tracking process and the collision analysis is continued until a termination event, such as absorption, leakage, or slowing down below a specified energy, occurs. The set of calculations for one neutron from source to termination is called a neutron history. A large number of histories is processed to estimate the space-energy neutron flux. Comparisons of results with CDC-7600 PACER solutions are favorable for several two dimensional test problems. 2 refs

Previous findings showed that hyperinsulinism and type 2 diabetes are positively associated with neural sympathetic and adrenal sympathetic activities, respectively. These peripheral sympathetic branches depend on the pontine (A5-noradrenergic and the rostral ventrolateral (C1-adrenergic medullary nuclei. They are excited by glutamate axons which act at NMDA postsynaptic receptors.Research design and methods: One OGTT plus placebo and one OGTT plus oral amantadine test were carried out two weeks apart in 15 caucasic normal voluntary humans. Noradrenaline, adrenaline, dopamine, plasma-free serotonin, platelet serotonin, glucose, glucagon, and insulin were measured throughout the 180-minute testing period.Results: Maximal reductions of plasma glucose and glucagon plus exacerbated insulin rises were significantly greater throughout the oral glucose plus amantadine test than those registered throughout the oral glucose plus placebo challenge. The above findings were paralleled by greater than normal noradrenaline/adrenaline plasma ratio increases. In addition, maximal reductions of the platelet serotonin and plasma serotonin circulating values contrasted with the normal rises of these parameters, always registered during the glucose load plus placebo challenge.Conclusion: This study supports the theory that

The impulsivity was measured by means of the Barratt Impulsivity Scale, version 11 (BIS-11, a widely used self-report questionnaire, and the platelet SERT was evaluated by means of the specific binding of 3H-paroxetine (3H-Par to platelet membranes, according to standardized protocols. The results showed that women had a higher BIS-11 total score than men, and also higher scores of two factors of the same scale: the motor impulsivity and the cognitive complexity. The analysis of the correlations revealed that the density of the SERT proteins, as measured by the maximum binding capacity (Bmax of 3H-Par, was significantly and positively related to the cognitive complexity factor, but only in men. Men showed also a significant and negative correlation with the dissociation constant, Kd, of (3H-Par binding, and the motor impulsivity factor. These findings suggest that women are generally more impulsive than men, but that the 5-HT system is more involved in the impulsivity of men than in that of women.Keywords: impulsivity, gender, serotonin transporter, Barratt Impulsivity Scale, platelets, 3H-paroxetine

    The TMT will consist of a 30-m filled-aperture segmented primary mirror and will include non-sidereal rate tracking capabilities for observing Solar System objects. Its sensitivity will be 14 times larger than that of 8-m class telescopes for seeing-limited observations -up to 200 times larger for background limited adaptive optics (AO) observations- and will allow high angular/spatial resolution with diffraction-limited capability in the near infrared. AO guiding will accommodate faint, small angular size solar system objects to serve as natural guide stars for non-sidereal observations. For Kuiper belt objects (KBOs), on-instrument wavefront sensors can crawl the field-of-view to look for background natural stars that can be used for tip/tilt correction. We will describe the main characteristics of the Thirty Meter Telescope, its first light instrumentation suite, and the most relevant science-driven requirements for its design, emphasizing the strengths of the TMT for Solar System astronomical research. Some real-case scenarios of sensitivities for solar system targets will be presented for the first-light instruments.Complementary information about TMT, and the opportunities it offers for planetary science research, will be presented at this meeting by Dumas et al., and at the TMT Solar System Town Hall event on Tuesday.The international TMT partnership includes Canada, China, India, Japan, Caltech, the University of California, and Funding is also provided by the Gordon and Betty Moore Foundation.

    Lamb wave interaction with flaws is a complex, three-dimensional phenomenon, which often frustrates signal interpretation schemes based on mode arrival time shifts predicted by dispersion curves. As the flaw severity increases, scattering and mode conversion effects will often dominate the time-domain signals, obscuring available information about flaws because multiple modes may arrive on top of each other. Even for idealized flaw geometries the scattering and mode conversion behavior of Lamb waves is very complex. Here, multi-mode Lamb waves in a metal plate are propagated across a rectangular flat-bottom hole in a sequence of pitch-catch measurements corresponding to the double crosshole tomography geometry. The flaw is sequentially deepened, with the Lamb wave measurements repeated at each flaw depth. Lamb wave tomography reconstructions are used to identify which waveforms have interacted with the flaw and thereby carry information about its depth. Multiple features are extracted from each of the Lamb wave signals using wavelets, which are then fed to statistical pattern classification algorithms that identify flaw severity. In order to achieve the highest classification accuracy, an optimal feature space is required but it’s never known a priori which features are going to be best. For structural health monitoring we make use of the fact that physical flaws, such as corrosion, will only increase over time. This allows us to identify feature vectors which are topologically well-behaved by requiring that sequential classes “line up” in feature vector space. An intelligent feature selection routine is illustrated that identifies favorable class distributions in multi-dimensional feature spaces using computational homology theory. Betti numbers and formal classification accuracies are calculated for each feature space subset to establish a correlation between the topology of the class distribution and the corresponding classification accuracy.

(Myofibroblasts are embedded in a sophisticated extracellular matrix (ECM that they secrete, and a complex and interactive dialogue exists between (myofibroblasts and their microenvironment. In addition to the secretion of the ECM, (myofibroblasts, by secreting matrix metalloproteinases and tissue inhibitors of metalloproteinases, are able to remodel this ECM. (Myofibroblasts and their microenvironment form an evolving network during tissue repair, with reciprocal actions leading to cell differentiation, proliferation, quiescence, or apoptosis, and actions on growth factor bioavailability by binding, sequestration, and activation. In addition, the (myofibroblast phenotype is regulated by mechanical stresses to which they are subjected and thus by mechanical signaling. In pathological situations (excessive scarring or fibrosis, or during aging, this dialogue between the (myofibroblasts and their microenvironment may be altered or disrupted, leading to repair defects or to injuries with damaged and/or cosmetic skin alterations such as wrinkle development. The intimate dialogue between the (myofibroblasts and their microenvironment therefore represents a fascinating domain that must be better understood in order not only to characterize new therapeutic targets and drugs able to prevent or treat pathological developments but also to interfere with skin alterations observed during normal aging or premature aging induced by a deleterious environment.

It acts as a reducing agent for the graphene oxide as well as a capping agent, allowing the formation of titanium dioxide nanoparticles with a narrow size distribution (~20 nm. Transmission electron micrographs show that the nanoparticles are uniformly distributed on the reduced graphene oxide nanosheet.

    Full Text Available One of the earliest morphogenetic processes in the development of many animals is epiboly. In the zebrafish, epiboly ensues when the animally localized blastoderm cells spread, thin over, and enclose the vegetally localized yolk. Only a few factors are known to function in this fundamental process. We identified a maternal-effect mutant, betty boop (bbp, which displays a novel defect in epiboly, wherein the blastoderm margin constricts dramatically, precisely when half of the yolk cell is covered by the blastoderm, causing the yolk cell to burst. Whole-blastoderm transplants and mRNA microinjection rescue demonstrate that Bbp functions in the yolk cell to regulate epiboly. We positionally cloned the maternal-effect bbp mutant gene and identified it as the zebrafish homolog of the serine-threonine kinase Mitogen Activated Protein Kinase Activated Protein Kinase 2, or MAPKAPK2, which was not previously known to function in embryonic development. We show that the regulation of MAPKAPK2 is conserved and p38 MAP kinase functions upstream of MAPKAPK2 in regulating epiboly in the zebrafish embryo. Dramatic alterations in calcium dynamics, together with the massive marginal constrictive force observed in bbp mutants, indicate precocious constriction of an F-actin network within the yolk cell, which first forms at 50% epiboly and regulates epiboly progression. We show that MAPKAPK2 activity and its regulator p38 MAPK function in the yolk cell to regulate the process of epiboly, identifying a new pathway regulating this cell movement process. We postulate that a p38 MAPKAPK2 kinase cascade modulates the activity of F-actin at the yolk cell margin circumference allowing the gradual closure of the blastopore as epiboly progresses.

  5. Critical heat flux (CHF) characteristics of high conversion pressurized water reactor with double flat core

    International Nuclear Information System (INIS)

    Thermal-hydraulic feasibility of a high conversion pressurized water reactor (HCPWR) with a double flat core was studied from a view point of minimum departure from nucleate boiling ratio (MDNBR). The proposed HCPWR improves uranium utilization under the same electrical output as a conventional 3-loop PWR. The critical heat flux (CHF) data of Bettis Atomic Power Laboratory were used to evaluate the predictive capability of KfK, EPRI-B and W and EPRI-Columbia correlations for triangular tight lattice cores. Among them, considering a predictive erroe band of 20%, the KfK correlation had the most promising features for a design purpose. The KfK correlation was applied to COBRA-IV-I steady-state subchannel analysis of the double-flat-core HCPWR under the same boundary conditions as the 3-loop PWR. As a result, it was revealed that the MDNBR of a reference design (fuel rod diameter: 9.5mm, control rod thimble diameter: 11.0mm and rod pitch: 11.4mm) satisfied the lower limit of MDNBR for a current PWR with a sufficient margin. Parametric studies clarified that: (1) The DNBR was increased with increasing the rod pitch or decreasing the control rod thimble diameter. (2) The radial peaking factor was recommended to be less than 1.72 under the present reference core disign. (3) A smaller fuel rod diameter required a larger pitch-to-diameter ratio (p/d) to satisfy the lower limit of MDNBR. Based on the steady-state MDNBR analysis results, the feasibility of the double-flat-core HCPWR was proved under proper considerations of core design and radial power distribution. (author)

    Full Text Available Betti Giusti, Anna Maria Gori, Rossella Marcucci, Claudia Saracini, Anna Vestrini, Rosanna AbbateDepartment of Medical and Surgical Critical Care, University of Florence, SOD Atherothrombotic Diseases, AOU Careggi, Florence, ItalyAbstract: The inhibition of platelet function by antiplatelet therapy determines the improvement of the survival of patients with clinically evident cardiovascular disease. Clopidogrel in combination with aspirin is the recommended standard of care for reducing the occurrence of cardiovascular events in patients with acute coronary syndromes undergoing percutaneous coronary intervention. However, major adverse cardiovascular events including stent thrombosis occur in patients taking clopidogrel and aspirin. A growing body of evidence demonstrates that high post-treatment platelet reactivity on antiplatelet treatment is associated with increased risk of adverse clinical events. Clopidogrel requires conversion to active metabolite by cytochrome P450 isoenzymes. The active metabolite inhibits ADP-stimulated platelet activation by irreversibly binding to P2Y12 receptors. Recently, the loss-of-function CYP2C19*2 allele has been associated with decreased metabolization of clopidogrel, poor antiaggregant effect, and increased cardiovascular events. In high risk vascular patients, the CYP2C19*2 polymorphism is a strong predictor of adverse cardiovascular events and particularly of stent thrombosis. Prospective studies evaluating if an antiplatelet treatment tailored on individual characteristics of patients, CYP2C19*2 genotypes, platelet phenotype, drug–drug interaction, as well as traditional and procedural risk factors, are now urgently needed for the identification of therapeutic strategies providing the best benefit for the single subject.Keywords: antiplatelet therapy, clopidogrel, cytochrome P450 2C19 loss-of-function polymorphism, major adverse cardiovascular events, percutaneous coronary interventions

    Full Text Available Michele M Straus, Udi E Ghitza, Betty Tai Center for the Clinical Trials Network, National Institute on Drug Abuse, National Institutes of Health, United States Department of Health and Human Services, Bethesda, MD, USA Abstract: The opioid overdose epidemic is an alarming and serious public health problem in the United States (US that has been escalating for 11 years. The 2011 National Survey on Drug Use and Health (NSDUH demonstrated that 1 in 20 persons in the US aged 12 or older reported nonmedical use of prescription painkillers in the past year. Prescription drug overdose is now the leading cause of accidental death in the United States – surpassing motor vehicle accidents. Great efforts have been initiated to curb the overdose crisis. Notable examples of these efforts are (1 the Drug Enforcement Administration’s (DEA National Take-Back Initiative instituted in 2010; (2 the Prescription Drug Monitoring Programs (PDMPs implemented in most US states to provide practitioners with point-of-care information regarding a patient's controlled substance use; (3 the naloxone rescue programs initiated in the community to avert mortality resulting from overdose. The use of naloxone rescue strategies has gained traction as an effective measure to prevent fatal opioid overdose. Many US federal-government agencies are working to make these strategies more accessible to first responders and community participants. This new approach faces many challenges, such as accessibility to naloxone and the equipment and training needed to administer it, but none is more challenging than the fear of legal repercussions. US federal-government agencies, local governments, health care institutions, and community-based organizations have begun to tackle these barriers, and naloxone take-home programs have gained recognition as a feasible and sensible preventive strategy to avoid a fatal result from opioid overdose. Although many challenges still need to be overcome

    This volume of the LLE Review, covering April-June 2005, features the following articles. ''High-Density and High ρR Fuel Assembly for Fast-Ignition Inertial Confinement Fusion'' by R. Betti and C. Zhou. In this article (p. 117), the authors optimize implosion parameters for fast-ignition inertial confinement fusion and design fast-ignition targets relevant to direct-drive inertial fusion energy (IFE). It is shown that a 750-kJ laser can assemble fuel with VI = 1.7 X 107 cm/s, a = 0.7, t = 400 g/cc, tR = 3 g/cm2, and a hot-spot volume of less than 10% of the compressed core. If fully ignited, this fuel assembly can produce energy gains of 150. In the second article (p. 122), C. Stoeckl, T. R. Boehly, J. A. Delettrez, V. Yu. Glebov, J. Miller, V. A. Smalyuk, W. Theobald, B. Yaakobi, and T. C. Sangster, along with J. A. Frenje, C. K. Li, R. D. Petrasso, and F. H. Séguin (MIT), S. P. Hatchett (LLNL), and R. B. Stephens (GA) describe recent OMEGA experiments that have studied the fuel assembly of gas-filled, cone-in-shell, fast-ignition targets. Using both fusion products and backlit images, an areal density of ~60-70 mg/cm2 was inferred for the dense core assembly. The results are promising for successful integrated fast-ignition experiments on the OMEGA EP facility, scheduled to be completed in 2007.

    Local caregivers such as psychiatric service providers, mental health welfare workers, and nursing-care staff have a major role to play in the long-term support of survivors of the Great Eastern Japan Earthquake of March 11th, 2011. Alcohol-related problems often cause various problems mentally, physically, economically, and socially. Alcoholics tend to show violent behavior, deny their own alcoholism, cause codependency in significant others, and occasionally relapse. Local caregivers bear the burden of caring for them and feel responsible for their relapse. This leads to exhaustion and discomfort with caring for them. In order to provide continuous and effective support for people with alcohol-related problems, it is important for caregivers to know the nature of the illness, the means and stages of recovery, effective support strategies, and how to enjoy providing support. A Leadership Training course on "Mental Health First Aid (MHFA)" was held in November 2011 for caregivers in Iwate Prefecture. MHFA provides help for people suffering from a mental health problem or in a mental health crisis, developed in Australia by Betty A. Kitchener and Anthony F. Jorm. In 2006, the MHFA-Japan (MHFA-J) Project Team translated the program and modified it to fit Japanese culture. The action plan consists of 5 part: 1) Approach the person, assess and assist with any crises, 2) Listen non-judgmentally, 3) Give support and information, 4) Encourage the person to get appropriate, professional help, 5) Encourage other support/self-help. During the leadership training course, MHFA for anxiety disorder, depression, suicidal thoughts, and alcohol-related problems was introduced, as well as how to train caregivers in experience-based and participatory approaches. The session for alcohol-related problems focused on the process of recovery, including how to deal with relapse, how to listen, how to motivate patients, and how to enjoy being a caregiver. There was also a role-play with

  17. Validation study of the reactor physics lattice transport code WIMSD-5B by TRX and BAPL critical experiments of light water reactors

    International Nuclear Information System (INIS)

    Highlights: • To validate the reactor physics lattice code WIMSD-5B by this analysis. • To model TRX and BAPL critical experiments using WIMSD-5B. • To compare the calculated results with experiment and MCNP results. • To rely on WIMSD-5B code for TRIGA calculations. - Abstract: The aim of this analysis is to validate the reactor physics lattice transport code WIMSD-5B by TRX (thermal reactor-one region lattice) and BAPL (Bettis Atomic Power Laboratory-one region lattice) critical experiments of light water reactors for neutronics analysis of 3 MW TRIGA Mark-II research reactor at AERE, Dhaka, Bangladesh. This analysis is achieved through the analysis of integral parameters of five light water reactor critical experiments TRX-1, TRX-2, BAPL-UO2-1, BAPL-UO2-2 and BAPL-UO2-3 based on evaluated nuclear data libraries JEFF-3.1 and ENDF/B-VII.1. In integral measurements, these experiments are considered as standard benchmark lattices for validating the reactor physics lattice transport code WIMSD-5B as well as evaluated nuclear data libraries. The integral parameters of the said critical experiments are calculated using the reactor physics lattice transport code WIMSD-5B. The calculated integral parameters are compared to the measured values as well as the earlier published MCNP results based on the Chinese evaluated nuclear data library CENDL-3.0 for assessment of deterministic calculation. It was found that the calculated integral parameters give mostly reasonable and globally consistent results with the experiment and the MCNP results. Besides, the group constants in WIMS format for the isotopes U-235 and U-238 between two data files have been compared using WIMS library utility code WILLIE and it was found that the group constants are well consistent with each other. Therefore, this analysis reveals the validation study of the reactor physics lattice transport code WIMSD-5B based on JEFF-3.1 and ENDF/B-VII.1 libraries and can also be essential to execute

It is an important protein of the extracellular matrix that contributes to the final structure of a microfibril. Few cases displaying an autosomal recessive transmission are reported in the world. The FBN1 gene, which is made of 66 exons, is located on chromosome 15q21.1. This review, after an introduction on the clinical manifestations that leads to the diagnosis of MFS, focuses on cardiovascular manifestations, pharmacological and surgical therapies of thoracic aortic aneurysm and/or dissection (TAAD, mechanisms underlying the progression of aneurysm or of acute dissection, and biomarkers associated with progression of TAADs. A Dutch group compared treatment with losartan, an angiotensin II receptor-1 blocker, vs no other additional treatment (COMPARE clinical trial. They observed that losartan reduces the aortic dilatation rate in patients with Marfan syndrome. Later on, they also reported that losartan exerts a beneficial effect on patients with Marfan syndrome carrying an FBN1 mutation that causes haploinsufficiency (quantitative mutation, while it has no significant effect on patients displaying dominant negative (qualitative mutations. Moreover, a French group in a 3-year trial compared the administration of

    Los Alamos National Laboratory, Carlsbad Office (LANL-CO), has been tasked to write Project Plans for all of the Small Quantity Sites (SQS) with defense related Transuranic (TRU) waste in the Department of Energy (DOE) complex. Transuranic Work-Off Plans were precursors to the Project Plans. LANL-CO prepared a Work-Off Plan for each small quantity site. The Work-Off Plan that identified issues, drivers, schedules, and inventory. Eight sites have been chosen to deinventory their legacy TRU waste; Bettis Atomic Power Laboratory, General Electric-Vallecitos Nuclear Center, Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory-Area 300, Nevada Test Site, Nuclear Radiation Development, Sandia National Laboratory, and the Separations Process Research Unit. Each plan was written for contact and/or remote handled waste if present at the site. These project plans will assist the small quantity sites to ship legacy TRU waste offsite and de-inventory the site of legacy TRU waste. The DOE is working very diligently to reduce the nuclear foot print in the United States. Each of the eight SQSs will be de-inventoried of legacy TRU waste during a campaign that ends September 2011. The small quantity sites have a fraction of the waste that large quantity sites possess. During this campaign, the small quantity sites will package all of the legacy TRU waste and ship to Idaho or directly to the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico. The sites will then be removed from the Transuranic Waste Inventory if they are de-inventoried of all waste. Each Project Plan includes the respective site inventory report, schedules, resources, drivers and any issues. These project plans have been written by the difficult waste team and will be approved by each site. Team members have been assigned to each site to write site specific project plans. Once the project plans have been written, the difficult team members will visit the sites to ensure nothing has

This study compares the growth of premature infants fed the current standard intake of protein (3.5 g/kg/day with the growth of those fed a higher amount (4.0 g/kg/day.Study design: Fifty-two infants <1500 g and <33 weeks gestational age participated in a blinded, single-center, prospective randomized control trial to compare growth between two groups of different protein-intake levels. Primary outcomes were average daily weight gain (g/kg/day, head-circumference (cm/kg/week and linear growth velocity (cm/kg/week. Secondary outcomes were serum indices of protein tolerance and plasma amino acid concentrations.Results: Infants receiving higher amounts of protein had higher rates of growth for body weight (18.2 ± 0.7 versus 16.2 ± 1.0 g/kg/day; P < 0.05 and head circumference (0.87 ± 0.08 versus 0.62 ± 0.07 cm/kg/week; P < 0.05, with no differences in blood protein or plasma amino acid concentrations. Length of hospital stay was 14 days shorter for the higher-protein group (51.4 ± 4.0 versus 65.9 ± 6.3 days.Conclusion: Increasing premature infant enteral protein supplementation from a calculated intake of 3.5–4.0 g/kg/day improved growth in a safe manner.Keywords: human milk, human milk fortifier, growth, low birth weight

This commentary discusses the scope and clinical implications of the public health problem of coexisting substance use and diabetes, including suggestions for future research. Diabetes is the seventh leading cause of death in the US, and is associated with many severe health complications like cardiovascular disease, stroke, kidney damage, and limb amputations. There are an estimated 24 million adults in the US with type 2 diabetes. Approximately 20% of adults aged 18 years or older with diabetes report current cigarette smoking. The prevalence of current alcohol use in the diabetic population is estimated to be around 50%–60% in epidemiological surveys and treatment-seeking populations. Cigarette smoking is associated with an increased risk of type 2 diabetes in a dose-dependent manner and is an independent modifiable risk factor for development of type 2 diabetes. Diabetic patients with an alcohol or other drug use disorder show a higher rate of adverse health outcomes. For example, these patients experience more frequent and severe health complications as well as an increased risk of hospitalization, and require longer hospital stays. They are also less likely to seek routine care for diabetes or adhere to diabetes treatment than those without an alcohol or other drug use disorder. The Affordable Care Act of 2010 and the Mental Health Parity Act and Addiction Equity Act of 2008 provide opportunities for facilitating integration of

This physiological disorder is responsible for gastrointestinal hypomotility, hyperglycemia, raised systolic blood pressure, raised heart rate, and other neuroendocrine disorders. Therefore, we prescribed neuropharmacological therapy to reverse this central and autonomic nervous system disorder, in order to normalize the clinical and neuroendocrine profile.Methods: The study included 22 female patients with anorexia nervosa (10 restricted type, 12 binge-eating type who received three months of treatment with amantadine 100 mg/day. We measured blood pressure, heart rate, and circulating neurotransmitters, (noradrenaline, adrenaline, dopamine, platelet serotonin, free plasma serotonin during supine resting, one minute of orthostasis, and a five-minute exercise test before and after one, two, and three months of treatment with amantadine, a drug which abrogates adrenal sympathetic activity by acting at the C1(Ad medullary nuclei responsible for this branch of the peripheral sympathetic activity.Results: We found the amantadine abolished symptoms of anorexia nervosa from the first oral dose onwards. Normalization of autonomic and cardiovascular parameters was demonstrated within the early days of therapy. Abrupt and sustained increases in the plasma noradrenaline

    Full Text Available La palabra hermenéutica como neologismo fue introducida en el lenguaje por el filósofo Dannhauer, en el año 1654, haciendo alusión a una ciencia general de la interpretación como propedéutica para todas las ciencias. Desde allí, en el horizonte del pasado, la palabra hermenéutica fue considerada por la mitología griega como enunciación del pensamiento, traducción, mandato o adivinación. Pero en Aristóteles la hermenéutica se empieza a concebir en tanto lenguaje, como análisis de los juicios, y en cuanto teoría jurídica, como comprensión, interpretación y creación. Así el uso del término hermeneia se extendió en el Medioevo, alrededor de lo teológico y lo jurídico. En lo teológico se aplicó un texto en particular, la Biblia, desarrollándose entre dos opuestos: lo alegórico expuesto por Filón de Alejandría, Orígenes y Augusto de Dacia y lo literal expuesto por Lutero, Philipp Melanchthon y Flacius Illyricus. En lo jurídico, la hermeneia se desarrolló entre la dogmática y la exégesis, consolidándose como una disciplina profesional. Ahora bien, la contemporaneidad del término hermenéutica como una ciencia general, al estilo de Dannhauer, fue seguida por Wolff, Chladenius y Meier y desde allí en su horizonte, la hermenéutica se constituye como concepto en Schleiermacher, Boeckh, Droysen, Dilthey y el jurista Betti; todos ellos le otorgan la posibilidad de método a la comprensión para postular verdades en las ciencias del espíritu, siguiendo el modelo de las ciencias naturales. Pero ya en el siglo XX, con Heidegger y Gadamer, la hermenéutica incurre de lleno en el problema del ser, es el giro de lo epistemológico a lo filosófico pues el concepto que sustenta las ciencias del espíritu es la formación. La hermenéutica, entonces, en tanto traducción de algo extraño en algo propio, posibilita permanentemente la formación del ser

    A British Medical Journal editor recorded her impressions and experiences at the Fourth World Conference on Women in the form of a 10-day diary. She described a logistical nightmare extending from her attempt to check into the hotel where she had a reservation to workshops and meetings held in unfinished buildings, overcrowded classrooms, and public areas of a hotel (even after hotel management extinguished the lights). The journalist's movements were dutifully recorded by a uniformed attendant, and taxi drivers refused to take her to the conference center. Early lobbying and strategy meetings revolved around the issues to be discussed at the conference. The opening of the Conference was marked with pomp and ceremony while workshops held at the nongovernmental (NGO) forum 50 miles away provided an opportunity for women to describe their attempts to improve their status. Rain forced Hilary Clinton to speak inside and disappointed thousands of women who had waited in line for hours to hear her comments. Betty Friedan described the conference as a metaphor for women's experience in the world and called for a "new vision of equality." Debates at the NGO forum centered around the rights of parents to have access to their children's medical records and punitive measures for women who have had abortions. At the Conference, the UN was unable to explain the paucity of women in positions of under secretary general or higher. By the end of the first week, the governments of Australia, India, Tanzania, China, the US, Ghana, the UK, Turkey, and Cambodia had all made commitments to improve the status of women. During the second week of the Conference the wording for the Beijing Declaration and Platform for Action was passed through various committees. The resulting document represents a significant contribution to the gradual progress towards equity for women, instead of a major shift in world view, but grassroots organizations will find in it the ammunition to hold governments

    V&V and UQ are the primary means to assess the accuracy and reliability of M&S and, hence, to establish confidence in M&S. Though other industries are establishing standards and requirements for the performance of V&V and UQ, at present, the nuclear industry has not established such standards or requirements. However, the nuclear industry is beginning to recognize that such standards are needed and that the resources needed to support V&V and UQ will be very significant. In fact, no single organization has sufficient resources or expertise required to organize, conduct and maintain a comprehensive V&V and UQ program. What is needed is a systematic and standardized approach to establish and provide V&V and UQ resources at a national or even international level, with a consortium of partners from government, academia and industry. Specifically, what is needed is a structured and cost-effective knowledge base that collects, evaluates and stores verification and validation data, and shows how it can be used to perform V&V and UQ, leveraging collaboration and sharing of resources to support existing engineering and licensing procedures as well as science-based V&V and UQ processes. The Nuclear Energy Knowledge base for Advanced Modeling and Simulation (NE-KAMS) is being developed at the Idaho National Laboratory in conjunction with Bettis Laboratory, Sandia National Laboratories, Argonne National Laboratory, Utah State University and others with the objective of establishing a comprehensive and web-accessible knowledge base to provide V&V and UQ resources for M&S for nuclear reactor design, analysis and licensing. The knowledge base will serve as an important resource for technical exchange and collaboration that will enable credible and reliable computational models and simulations for application to nuclear power. NE-KAMS will serve as a valuable resource for the nuclear industry, academia, the national laboratories, the U.S. Nuclear Regulatory Commission (NRC) and

We used behavioral measures and functional magnetic resonance imaging to investigate the response to experimental thermal stimuli with APAP or placebo administration. Region-of-interest analysis revealed that activity in response to noxious stimulation diminished with APAP compared to placebo in prefrontal cortices, insula, thalami, anterior cingulate cortex, and periaqueductal gray matter.Conclusion: These findings suggest an inhibitory effect of APAP on spinothalamic tracts leading to a decreased activation of higher structures, and a top-down influence on descending inhibition. Further binding and connectivity studies are needed to evaluate how APAP modulates pain, especially in the context of repeated

    The Nuclear Energy Computational Fluid Dynamics Advanced Modeling and Simulation (NE-CAMS) system is being developed at the Idaho National Laboratory (INL) in collaboration with Bettis Laboratory, Sandia National Laboratory (SNL), Argonne National Laboratory (ANL), Utah State University (USU), and other interested parties with the objective of developing and implementing a comprehensive and readily accessible data and information management system for computational fluid dynamics (CFD) verification and validation (V&V) in support of nuclear energy systems design and safety analysis. The two key objectives of the NE-CAMS effort are to identify, collect, assess, store and maintain high resolution and high quality experimental data and related expert knowledge (metadata) for use in CFD V&V assessments specific to the nuclear energy field and to establish a working relationship with the U.S. Nuclear Regulatory Commission (NRC) to develop a CFD V&V database, including benchmark cases, that addresses and supports the associated NRC regulations and policies on the use of CFD analysis. In particular, the NE-CAMS system will support the Department of Energy Office of Nuclear Energy Advanced Modeling and Simulation (NEAMS) Program, which aims to develop and deploy advanced modeling and simulation methods and computational tools for reliable numerical simulation of nuclear reactor systems for design and safety analysis. Primary NE-CAMS Elements There are four primary elements of the NE-CAMS knowledge base designed to support computer modeling and simulation in the nuclear energy arena as listed below. Element 1. The database will contain experimental data that can be used for CFD validation that is relevant to nuclear reactor and plant processes, particularly those important to the nuclear industry and the NRC. Element 2. Qualification standards for data evaluation and classification will be incorporated and applied such that validation data sets will result in well

    efficacy of HD arsenic in dark leaf spot control in field has been shown for the first time: since fungal inoculation was performed on the leaves before flowering, we can hypothesize that this treatment induced an increase of plant resistance to fungal infection. Conclusions: This research showed the possibility of using HD arsenic in agriculture (“agrohomeopathy”, as it increased both plant resistance to fungal infection and the content of glucosinolates, ie secondary metabolites involved in plant resistance mechanisms [2] and considered as “plant food protection agents” [3].

  12. Nuclear Energy CFD Application Management System

    International Nuclear Information System (INIS)

    In modeling and simulation (M and S), it is virtually impossible to separately evaluate the effectiveness of the model from the data used because the results produced rely heavily on the interaction between the two. Both the data and the simulation are responsible for achieving the ultimate goal of providing defensible research and development (R and D) products and decisions. It is therefore vital that data verification and validation (V and V) activities, along with stringent configuration management, be considered part of the overall M and S accreditation process. In support of these goals is the Nuclear Energy CFD Application Management System (NE-CAMS) for nuclear system design and safety analysis. Working with Bettis Laboratory and Utah State University, a plan of action is being developed by the Idaho National Laboratory (INL) that will address the highest and most immediate needs to track and manage computational fluid dynamics (CFD) models and experimental data in an electronic database. The database will intrinsically incorporate the Nuclear Regulatory Commission (NRC) approved policies and procedures for quality. The quality requirements will be such that the model and data must conform to the quality specifications outlined by the NRC before they can be entered into the database. The primary focus of this database is CFD V and V for nuclear industry needs and will, in practice, serve as the best practice guideline that will accommodate NRC regulations. Such a database, along with a prescriptive methodology for how to utilize it, will provide the NRC with accepted CFD results that could potentially be used for licensing. Input from major organizations in government and industry have shown the need to develop a coordinated strategy at a national level to effectively accelerate the use of CFD for nuclear systems design and safety analysis. The growth of CFD for nuclear applications is evident from publications, both in journals and conferences, where CFD

    confirmed by the fact that they were used as bookkeeping material by editorial offices. The publisher agreements also provide an idea of the actual royalties. In the article, poetess Betti Alver’s publisher agreements from the end of 1940 are used as an example. A concrete example of the politics of royalties used in the article is what happened with poetess Ilmi Kolla (1933–1954. Kolla’s correspondence and several manuscript notes open up a view of the background to her creative work, and show the role of royalties in an age of ideological demands and the effort to create suitable poems. In the 1940s and 1950s, royalties were relatively large in comparison with the standard of living, constituting Ilmi Kolla’s main source of income and contributing to creative conformism. The Soviet system’s royalty politics can indeed be seen as a kind of hidden bonus which stimulated authors to write conformist texts, revealing the relationship between ideology and material aspects.

The knowledge base will serve as an important resource for technical exchange and collaboration that will enable credible and reliable computational models and simulations for application to nuclear reactor design, analysis and licensing. NE-KAMS will serve as a valuable resource for the nuclear industry, academia, the national laboratories, the U.S. Nuclear Regulatory Commission (NRC) and the public and will help ensure the safe, economical and reliable operation of existing and future nuclear reactors. From its inception, NE-KAMS will directly support nuclear energy research, development and demonstration programs within the U.S. Department of Energy (DOE), including the CASL, NEAMS, Light Water Reactor Sustainability (LWRS), Small Modular Reactors (SMR), and Next Generation Nuclear Power Plant (NGNP) programs. These programs all involve M&S of nuclear reactor systems, components and processes, and it is envisioned that NE-KAMS will help to coordinate and facilitate collaboration and sharing of resources and expertise for V&V and UQ across these programs.

    This volume of the LLE Review, covering July-September 2000, begins with an article by T. R. Boehly, V. N. Goncharov, O. Gotchev, J. P. Knauer, D. D. Meyerhofer, D. Oron, S. P. Regan, Y. Srebro, W. Seka, D. Shvarts, S. Skupsky, and V.A. Smalyuk, who describe measurements of the effect of beam smoothing and pulse shape on imprinting. (Imprinting is defined as the imposition of pressure perturbations on the target by spatial variations in the laser intensity.) A principal result is the observation of reduced levels of imprint with the higher beam smoothing afforded by 1-THz smoothing by spectral dispersion (SSD). Additional highlights of research presented in this issue are: (1) P. W. McKenty, V. N. Goncharov, R. P. J. Town, S. Skupsky, R. Betti, and R. L. McCrory describe calculations of directly driven ignition capsule performance on the National Ignition Facility (NIF). The authors detail how the various contributors to implosion disruption (laser imprint, power imbalance, and target roughness) affect target performance and final gain. The conclusions are obtained by examining the simulated target evolution with the two-dimensional hydrodynamics computer code ORCHID. (2) D. D. Meyerhofer, J. A. Delettrez, R. Epstein, V. Yu.

    The SCSN is the modern digital ground motion seismic network in Southern California and performs the following tasks: 1) Operates remote seismic stations and the central data processing systems in Pasadena; 2) Generates and reports real-time products including location, magnitude, ShakeMap, aftershock probabilities and others; 3) Responds to FEMA, CalOES, media, and public inquiries about earthquakes; 4) Manages the production, archival, and distribution of waveforms, phase picks, and other data at the SCEDC; 5) Contributes to development and implementation of the demonstration EEW system called CISN ShakeAlert. Initially, the ShakeAlert project was funded through the US Geological Survey (USGS) and in early 2012, the Gordon and Betty Moore Foundation provided three years of new funding for EEW research and development for the US west coast. Recently, we have also received some Urban Areas Security Initiative (UASI) funding to enhance the EEW capabilities for the local UASI region by making our system overall faster, more reliable and redundant than the existing system. The additional and upgraded stations will be capable of decreasing latency and ensuring data delivery by using more reliable and redundant telemetry pathways. Overall, this will enhance the reliability of the earthquake early warnings by providing denser station coverage and more resilient data centers than before. * Seismic Datalogger upgrade: replaces existing dataloggers with modern equipment capable of sending one-second uncompressed packets and utilizing redundant Ethernet telemetry. * GPS upgrade: replaces the existing GPS receivers and antennas, especially at "zipper array" sites near the major faults, with receivers that perform on-board precise point positioning to calculate position and velocity in real time and stream continuous data for use in EEW calculations. * New co-located seismic/GPS stations: increases station density and reduces early warning delays that are incurred by travel

    2013-12-01

    Earthquake Early Warning (EEW) is a proven use of seismological science that can give people and businesses outside the epicentral area of a large earthquake up to a minute to take protective actions before the most destructive shaking hits them. Since 2006 several organizations have been collaborating to create such a system in the United States. These groups include the US Geological Survey, Caltech, UC Berkeley, the University of Washington, the Southern California Earthquake Center, the Swiss Federal Institute of Technology, Zürich, the California Office of Emergency Services, and the California Geological Survey. A demonstration version of the system, called ShakeAlert, began sending test notifications to selected users in California in January 2012. In August 2012 San Francisco's Bay Area Rapid Transit district began slowing and stopping trains in response to strong ground shaking. The next step in the project is to progress to a production prototype for the west coast. The system is built on top of the considerable technical and organizational earthquake monitoring infrastructure of the Advanced National Seismic System (ANSS). While a fully functional, robust, public EEW system will require significant new investment and development in several major areas, modest progress is being made with current resources. First, high-quality sensors must be installed with sufficient density, particularly near source faults. Where possible, we are upgrading and augmenting the existing ANSS networks on the west coast. Second, data telemetry from those sensors must be engineered for speed and reliability. Next, robust central processing infrastructure is being designed and built. Also, computer algorithms to detect and characterize the evolving earthquake must be further developed and tested. Last year the Gordon and Betty Moore Foundation funded USGS, Caltech, UCB and UW to accelerate R&D efforts. Every available means of distributing alerts must be used to insure the

    The Dean and Betty Gallo Prostate Cancer Center (GPCC) was established with the goal of eradicating prostate cancer and improving the lives of men at risk for the disease through research, treatment, education and prevention. GPCC was founded in the memory of Dean Gallo, a beloved New Jersey Congressman who died tragically of prostate cancer diagnosed at an advanced stage. GPCC unites a team of outstanding researchers and clinicians who are committed to high-quality basic research, translation of innovative research to the clinic, exceptional patient care, and improving public education and awareness of prostate cancer. GPCC is a center of excellence of The Cancer Institute of New Jersey, which is the only NCI-designated comprehensive cancer center in the state. GPCC efforts are now integrated well as part of our Prostate Program at CINJ, in which Dr. Robert DiPaola and Dr. Cory Abate-Shen are co-leaders. The Prostate Program unites 19 investigators from 10 academic departments who have broad and complementary expertise in prostate cancer research. The overall goal and unifying theme is to elucidate basic mechanisms of prostate growth and oncogenesis, with the ultimate goal of promoting new and effective strategies for the eradication of prostate cancer. Members' wide range of research interests collectively optimize the chances of providing new insights into normal prostate biology and unraveling the molecular pathophysiology of prostate cancer. Cell culture and powerful animal models developed by program members recapitulate the various stages of prostate cancer progression, including prostatic intraepithelial neoplasia, adenocarcinoma, androgen-independence, invasion and metastases. These models promise to further strengthen an already robust program of investigator-initiated therapeutic clinical trials, including studies adopted by national cooperative groups. Efforts to translate laboratory results into clinical studies of early detection and

    Cornell University Emeritus Professor of Physics, Kenneth I. Greisen, died on March 17, 2007 of cancer at the Hospicare residence in Ithaca, New York. He was 89 years old. Prof. Greisen was well-known for his participation in the Manhattan Project at Los Alamos and for his many contributions to the study of cosmic ray physics. More quietly, Prof. Greisen also made significant contributions to the teaching of Physics at the high school and university levels. He was of service to the Cornell and Ithaca communities in many ways both during his university career and after his retirement. Kenneth Ingvard Greisen was born in Perth Amboy, New Jersey, on January 24, 1918, to Signa and Ingvard Greisen. Ken attended Wagner College 1934-1935 and then Franklin and Marshall College, where he ran on the track team and graduated summa cum laude with the prestigious Henry S. Williamson Medalist award in 1938. Ken then entered graduate school in physics at Cornell University, where he became the first American student of the eminent Italian physicist Bruno B. Rossi. Together they carried out a study that yielded quantitative verification of the relativistic dilation of time intervals and an improved estimate of the mean life of mesotrons at rest. Their review article on ``Cosmic Ray Theory'' in 1941 was a standard for many years. Ken's Ph.D. thesis entitled ``Intensity of Cosmic Rays at Low Altitude and the Origin of the Soft Component,'' along with related articles, appeared in 1942 and 1943. During this very productive period, Ken also married Betty Chase, a Cornell biology graduate student. Upon graduation, Ken joined the Manhattan Project in Los Alamos, New Mexico. He was among the leaders of the group that designed and built the explosive charge that initiated the nuclear reaction in the first atomic bomb. Witnessing the July 16, 1945 Trinity explosion, he provided an eyewitness account that has become an important historical record. After the explosion, in a remark typical of

    University Press. When Stanford also published his final book One Time Fits All: The Campaigns for Global Uniformity, he was very proud of the glowing endorsement from Peter Galison, one of the country's foremost historians of science. With this book Ian also became the world's expert on the International Date Line, time zones, and standard time, among other aspects of time. Ian's historical work was supported by the National Science Foundation, the Dudley Observatory, and the National Maritime Museum of the Royal Observatory at Greenwich, where his work was highly regarded. He was active in many professional organizations, including the Historical Astronomy Division of the American Astronomical Society. On 29 March 2008 almost exactly 50 years after the death of his father, a memorial service was held in the library of the U. S. Naval Observatory, which had become Ian's second home during his researches, often accompanied by his wife Betty, to whom he dedicated his last book, calling her his "steadfast partner in this endeavor." The service, entitled "The Time of His Life: A Celebration of Research in the Development of Standard Timekeeping," included remarks by numerous colleagues and friends, surrounded by the books he so loved. Ian is survived by his wife of 47 years, Elizabeth Hodgins Bartky of Bethesda, Maryland, a son David J. Bartky, and a daughter Anne B. Goldberg.

  9. A Brief History of the Soil Science Society of America

    Brevik, Eric C.

    2013-04-01

    The Soil Science Society of America (SSSA) was officially born on November 18, 1936 at the Mayflower Hotel in Washington, D.C. with Richard Bradfield as the first President. SSSA was created from the merger of the American Soil Survey Association and the Soils Section of American Society of Agronomy (ASA). Six sections were established: 1) physics, 2) chemistry, 3) microbiology, 4) fertility, 5) morphology, and 6) technology, and total membership was less than 200. The first issue of SSSA Journal, then called SSSA Proceedings, published 87 items totaling 526 pages. The first recorded bank balance for SSSA was at the end of the 1937-38 fiscal year, and showed the Society to be worth 1,300.03. The Soils Section of ASA became the official American section of the International Society of Soil Science in 1934, and the new SSSA inherited that distinction which it retains to this day. SSSA has grown significantly since those early days. The original six sections have grown to 11 divisions, and some of those divisions have changed their names to reflect changes occurring within soil science. For example, the original section 5, morphology, is now Division S05 - Pedology after spending many years under other names such as Division V - Soil Classification and Division S-5 - Soil Genesis, Morphology, and Classification. SSSA was incorporated in the State of Wisconsin, USA on 22 January, 1952. Several awards have been developed to recognize achievement in the field of soil science, including the SSSA Presidential Award, Don and Betty Kirkham Soil Physics Award, Emil Truog Soil Science Award, International Soil Science Award, Irrometer Professional Certification Service Award, L.R. Ahuja Ag Systems Modeling Award, Marion L. and Chrystie M. Jackson Soil Science Award, Soil Science Applied Research Award, Soil Science Distinguished Service Award, Soil Science Education Award, Soil Science Industry and Professional Leadership Award, Soil Science Research Award, and SSSA Early

    2003-12-01

    Ernest H. Cherrington, Jr., a long-time member of the AAS, died in San Jose, California on 13 July 1996, following a long illness. He had a short but active career as a research astronomer at Perkins Observatory at Ohio Wesleyan University in Delaware, Ohio before World War II, in which he served as an officer in the Army Air Force. After the war ended he turned to full-time teaching and administration at the University of Akron, and then at Hood College in Frederick, Maryland. Ernest was born on 10 September 1909 in Westerville, Ohio, where his father, Ernest H. Cherrington, Sr., was a leader in the temperance movement and publisher of "American Issue", a Prohibitionist magazine. Ernest Jr.'s mother, Betty Clifford (née Denny) Cherrington, was a homemaker. He was an outstanding student in high school and at Ohio Wesleyan University, which he entered in 1927. The little university's Perkins Observatory with its 69-inch reflector, briefly the second largest telescope in the United States, had just been built and gone into operation. After graduating with a BA magna cum laude in astronomy in 1931, Ernest stayed on one more year and earned his MS with a thesis on the motion of material in the tail of Comet Morehouse, supervised by Nicholas T. Bobrovnikoff. In 1932 Ernest entered the University of California at Berkeley as a graduate student, with a one-year teaching assistantship in the Astronomical Department. This was followed by a two-year Lick Observatory Fellowship. In June 1933 he married Ann McAfee Naylor, who had been a classmate at Delaware High School and Ohio Wesleyan. Ernest did his PhD thesis on spectrophotometry of the Mg I b lines in the solar spectrum, using a high-resolution grating spectrograph on the Berkeley campus, designed by C. Donald Shane, his adviser. In this thesis, Ernest tested and improved the then current theory of strong absorption lines in stellar atmospheres. He also spent several short periods at Lick Observatory on Mount Hamilton

    2009-01-01

    Philip Solomon, one of the pioneers and leading researchers in molecular astrophysics, died on 30 April 2008 at his apartment on the upper west side of Manhattan after a battle with cancer. His pioneering research included both theoretical and very extensive observational studies of stellar atmospheres, interstellar molecules, high redshift galaxies, and the Earth's stratosphere. Phil was Distinguished Professor at The State University of New York [SUNY], Stony Brook, where he had been since 1974. Phil was born on 29 March 1939 in Manhattan, New York City, to Nat and Betty Solomon. Nat Solomon was a labor organizer and a printer. Phil attended the University of Wisconsin, where he received his BS in 1959 and where he met his future wife Sheila who was studying art. His Ph.D., "On the Role of Light Molecules in Astrophysics," was also from the University of Wisconsin under the guidance of Art Code and Bob Bless. After postdoctoral positions at Princeton and lectureships at Columbia and the University of California, San Diego, Phil spent two years as a Professor at the University of Minnesota. After two years at the Institute for Advanced Study in Princeton, he came to SUNY, Stony Brook, as Professor of Astronomy in the Department of Earth and Space Sciences. In 1988 Phil was selected as a Humboldt Senior Distinguished Scientist, and, in 1999, he was honored with the rank of Distinguished Professor at SUNY. Phil took sabbatical and other leaves at Churchill College and the Institute of Astronomy, Cambridge; the Institute for Advanced Study; l'Ecole Normale Superieure, Paris; Institut d'Astrophysique, Paris; and the Institut de Radioastronomie Millimetrique [IRAM], France. Phil published more than 160 papers and supervised seven Ph.D. students. He served on numerous review, visiting, and advisory panels. Phil's first theoretical research focused on opacity and abundance of light molecules such as H2, CO, and CN in stellar atmospheres, but then shifted quickly to the

    . His legacy is that he succeeded in both areas. Don enjoyed a life-long interest in photography, carpentry and woodworking. In retirement, he spent a great deal of time on family genealogy. He possessed a strong "do-it-yourself" philosophy, manifested for example in clearing land and building a cottage on Georgian Bay, a family project during his younger years. Don died in Toronto of natural causes. He is survived by his older sister Jean Borden, and his three sons David, Charles, and Andrew. Don's wife Betty predeceased him by about one year. He is also survived by his four granddaughters and two grandsons, in all of whom he delighted, as well as nieces and nephews who were particularly dear to him.

  17. Obituary: Hans Albrecht Bethe, 1906-2005

    of massive stellar cores would cause them to collapse to well above nuclear density, contrary to prevailing opinion. With James Applegate and James Lattimer, they published their finding in the BBAL ('"babble") paper of 1979. After that, astrophysics never quite left Bethe again, and with Brown (his "junior collaborator"), he took an interest in the fate of massive stars and black holes more generally. The series of papers on formation of black holes, gamma-ray bursts, and gravity-wave sources continued until close to his death. These papers are done very much the H.A. Bethe Way, often finding simple approximations to much more complicated work of others, and are quite straightforward. An inevitable part of the Bethe-Brown collaboration was a January stay in California; during the 1999 edition I had the good fortune of becoming a small footnote to the great Bethe story. Gerry and Hans invited me to join them for a while, to discuss issues of binary star evolution and population synthesis. I have to admit to being rather taken aback by the way in which the 93-year old gave me a good intellectual runaround every day. And yet, as many others have commented, there was nothing facetious or overbearing in his manner: He made me feel like a valuable colleague and welcome guest. Good meals were an essential part of Hans's every day, and during a dinner prepared by Rose Bethe and Betty Brown, the old stories surfaced. I could not resist asking about the legendary story of Rose and Hans's evening walk under the stars. Hans, so says the story, tried to impress his fiancée by commenting that at that moment, he was probably the only person on Earth who understood why the stars shine. Hans grinned a bit sheepishly, but Rose roundly confirmed the story with a big smile. Not too impressed, she had replied: "That's nice." And so it was.

    Full Text Available “New new media” - that is, media newer than new media, such as Twitter, Facebook, and YouTube, which turn consumers into producers, and are available free of charge to everyone - continued to grow in numbers of users and influence in late 2009 and 2010. Among the specific consequences of this growth: Traditional paper newspapers have continued to sharply decline in circulation, advertising revenue, and numbers of pages. Network television news in America, and network entertainment television, have also declined in numbers of viewers. YouTube and Face book have created new stars such as Susan Boyle and revived the careers of traditional stars such as Betty White. Face book and Twitter were of enormous help in getting crucial information in and out of Haiti in the aftermath of its devastating earthquake. New new media, however, have not only been used to bring assistance to suffering humans - new new media have been used as vehicles of propaganda by all political persuasions, as, for example, the Taliban channel on YouTube. Traditional continue to attempt to offer alternatives to new new media - Oxford University Press now offers bibliographies online compiled by professional scholars, in contrast to the pages of Wikipedia, on which anyone on the Web can write and edit. But Wikipedia continues to attract millions of readers - each of whom can instantly become a writer and editor - and the impact of new new media continues to expand and have influence over the content of older media. In 2010, a hit motion picture was released about the creation of Face book, and a major television network in the United States (CBS put on a television show based on someone’s Tweets. The Library of Congress in the United States of America is now archiving all Tweets. That one act shows that, although just 140 characters in the length, the Tweet - as are all products of new new media - is of enormous importance in our work, play, and lives. Their increase in the
