    We present a prototype implementation of SOS meta-theory in the Maude term rewriting language. The prototype defines the basic concepts of SOS meta-theory (e.g., transition formulae, deduction rules and transition system specifications) in Maude. Besides the basic definitions, we implement methods

  2. Lifting Term Rewriting Derivations in Constructor Systems by Using Generators

    2015-01-01

    Full Text Available Narrowing is a procedure that was first studied in the context of equational E-unification and that has been used in a wide range of applications. The classic completeness result due to Hullot states that any term rewriting derivation starting from an instance of an expression can be "lifted" to a narrowing derivation, whenever the substitution employed is normalized. In this paper we adapt the generator- based extra-variables-elimination transformation used in functional-logic programming to overcome that limitation, so we are able to lift term rewriting derivations starting from arbitrary instances of expressions. The proposed technique is limited to left-linear constructor systems and to derivations reaching a ground expression. We also present a Maude-based implementation of the technique, using natural rewriting for the on-demand evaluation strategy.

  3. Rewriting Logic Semantics of a Plan Execution Language

    The Plan Execution Interchange Language (PLEXIL) is a synchronous language developed by NASA to support autonomous spacecraft operations. In this paper, we propose a rewriting logic semantics of PLEXIL in Maude, a high-performance logical engine. The rewriting logic semantics is by itself a formal interpreter of the language and can be used as a semantic benchmark for the implementation of PLEXIL executives. The implementation in Maude has the additional benefit of making available to PLEXIL designers and developers all the formal analysis and verification tools provided by Maude. The formalization of the PLEXIL semantics in rewriting logic poses an interesting challenge due to the synchronous nature of the language and the prioritized rules defining its semantics. To overcome this difficulty, we propose a general procedure for simulating synchronous set relations in rewriting logic that is sound and, for deterministic relations, complete. We also report on the finding of two issues at the design level of the original PLEXIL semantics that were identified with the help of the executable specification in Maude.

  4. Simulation and Verification of Synchronous Set Relations in Rewriting Logic

    2011-01-01

    This paper presents a mathematical foundation and a rewriting logic infrastructure for the execution and property veri cation of synchronous set relations. The mathematical foundation is given in the language of abstract set relations. The infrastructure consists of an ordersorted rewrite theory in Maude, a rewriting logic system, that enables the synchronous execution of a set relation provided by the user. By using the infrastructure, existing algorithm veri cation techniques already available in Maude for traditional asynchronous rewriting, such as reachability analysis and model checking, are automatically available to synchronous set rewriting. The use of the infrastructure is illustrated with an executable operational semantics of a simple synchronous language and the veri cation of temporal properties of a synchronous system.

  5. Specification and Verification of Web Applications in Rewriting Logic

    Science.gov (United States)

    Alpuente, María; Ballis, Demis; Romero, Daniel

    This paper presents a Rewriting Logic framework that formalizes the interactions between Web servers and Web browsers through a communicating protocol abstracting HTTP. The proposed framework includes a scripting language that is powerful enough to model the dynamics of complex Web applications by encompassing the main features of the most popular Web scripting languages (e.g. PHP, ASP, Java Servlets). We also provide a detailed characterization of browser actions (e.g. forward/backward navigation, page refresh, and new window/tab openings) via rewrite rules, and show how our models can be naturally model-checked by using the Linear Temporal Logic of Rewriting (LTLR), which is a Linear Temporal Logic specifically designed for model-checking rewrite theories. Our formalization is particularly suitable for verification purposes, since it allows one to perform in-depth analyses of many subtle aspects related to Web interaction. Finally, the framework has been completely implemented in Maude, and we report on some successful experiments that we conducted by using the Maude LTLR model-checker.

  8. Rewriting and suppressing UMLS terms for improved biomedical term identification

    2010-03-01

    Full Text Available Abstract Background Identification of terms is essential for biomedical text mining.. We concentrate here on the use of vocabularies for term identification, specifically the Unified Medical Language System (UMLS. To make the UMLS more suitable for biomedical text mining we implemented and evaluated nine term rewrite and eight term suppression rules. The rules rely on UMLS properties that have been identified in previous work by others, together with an additional set of new properties discovered by our group during our work with the UMLS. Our work complements the earlier work in that we measure the impact on the number of terms identified by the different rules on a MEDLINE corpus. The number of uniquely identified terms and their frequency in MEDLINE were computed before and after applying the rules. The 50 most frequently found terms together with a sample of 100 randomly selected terms were evaluated for every rule. Results Five of the nine rewrite rules were found to generate additional synonyms and spelling variants that correctly corresponded to the meaning of the original terms and seven out of the eight suppression rules were found to suppress only undesired terms. Using the five rewrite rules that passed our evaluation, we were able to identify 1,117,772 new occurrences of 14,784 rewritten terms in MEDLINE. Without the rewriting, we recognized 651,268 terms belonging to 397,414 concepts; with rewriting, we recognized 666,053 terms belonging to 410,823 concepts, which is an increase of 2.8% in the number of terms and an increase of 3.4% in the number of concepts recognized. Using the seven suppression rules, a total of 257,118 undesired terms were suppressed in the UMLS, notably decreasing its size. 7,397 terms were suppressed in the corpus. Conclusions We recommend applying the five rewrite rules and seven suppression rules that passed our evaluation when the UMLS is to be used for biomedical term identification in MEDLINE. A software

  12. Dist-Orc: A Rewriting-based Distributed Implementation of Orc with Formal Analysis

    Directory of Open Access Journals (Sweden)

    José Meseguer

    2010-09-01

    Full Text Available Orc is a theory of orchestration of services that allows structured programming of distributed and timed computations. Several formal semantics have been proposed for Orc, including a rewriting logic semantics developed by the authors. Orc also has a fully fledged implementation in Java with functional programming features. However, as with descriptions of most distributed languages, there exists a fairly substantial gap between Orc's formal semantics and its implementation, in that: (i programs in Orc are not easily deployable in a distributed implementation just by using Orc's formal semantics, and (ii they are not readily formally analyzable at the level of a distributed Orc implementation. In this work, we overcome problems (i and (ii for Orc. Specifically, we describe an implementation technique based on rewriting logic and Maude that narrows this gap considerably. The enabling feature of this technique is Maude's support for external objects through TCP sockets. We describe how sockets are used to implement Orc site calls and returns, and to provide real-time timing information to Orc expressions and sites. We then show how Orc programs in the resulting distributed implementation can be formally analyzed at a reasonable level of abstraction by defining an abstract model of time and the socket communication infrastructure, and discuss the assumptions under which the analysis can be deemed correct. Finally, the distributed implementation and the formal analysis methodology are illustrated with a case study.

  14. Termination of canonical context-sensitive rewriting and productivity of rewrite systems

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Termination of programs, i.e., the absence of infinite computations, ensures the existence of normal forms for all initial expressions, thus providing an essential ingredient for the definition of a normalization semantics for functional programs. In lazy functional languages, though, infinite data structures are often delivered as the outcome of computations. For instance, the list of all prime numbers can be returned as a neverending stream of numerical expressions or data structures. If such streams are allowed, requiring termination is hopeless. In this setting, the notion of productivity can be used to provide an account of computations with infinite data structures, as it "captures the idea of computability, of progress of infinite-list programs" (B.A. Sijtsma, On the Productivity of Recursive List Definitions, ACM Transactions on Programming Languages and Systems 11(4:633-649, 1989. However, in the realm of Term Rewriting Systems, which can be seen as (first-order, untyped, unconditional functional programs, termination of Context-Sensitive Rewriting (CSR has been showed equivalent to productivity of rewrite systems through appropriate transformations. In this way, tools for proving termination of CSR can be used to prove productivity. In term rewriting, CSR is the restriction of rewriting that arises when reductions are allowed on selected arguments of function symbols only. In this paper we show that well-known results about the computational power of CSR are useful to better understand the existing connections between productivity of rewrite systems and termination of CSR, and also to obtain more powerful techniques to prove productivity of rewrite systems.

    The description of a single state of a modelled system is often complex in practice, but few procedures for synthesis address this problem in depth. We study systems in which a state is described by an arbitrary finite structure, and changes of the state are represented by structure rewriting rules, a generalisation of term and graph rewriting. Both the environment and the controller are allowed to change the structure in this way, and the question we ask is how a strategy for the controller that ensures a given property can be synthesised.

  1. A Rewriting Logic Approach to Type Inference

    Science.gov (United States)

    Ellison, Chucky; Şerbănuţă, Traian Florin; Roşu, Grigore

    Meseguer and Roşu proposed rewriting logic semantics (RLS) as a programing language definitional framework that unifies operational and algebraic denotational semantics. RLS has already been used to define a series of didactic and real languages, but its benefits in connection with defining and reasoning about type systems have not been fully investigated. This paper shows how the same RLS style employed for giving formal definitions of languages can be used to define type systems. The same term-rewriting mechanism used to execute RLS language definitions can now be used to execute type systems, giving type checkers or type inferencers. The proposed approach is exemplified by defining the Hindley-Milner polymorphic type inferencer mathcal{W} as a rewrite logic theory and using this definition to obtain a type inferencer by executing it in a rewriting logic engine. The inferencer obtained this way compares favorably with other definitions or implementations of mathcal{W}. The performance of the executable definition is within an order of magnitude of that of highly optimized implementations of type inferencers, such as that of OCaml.

    2014-03-01

    Full Text Available String diagrams are a powerful tool for reasoning about physical processes, logic circuits, tensor networks, and many other compositional structures. Dixon, Duncan and Kissinger introduced string graphs, which are a combinatoric representations of string diagrams, amenable to automated reasoning about diagrammatic theories via graph rewrite systems. In this extended abstract, we show how the power of such rewrite systems can be greatly extended by introducing pattern graphs, which provide a means of expressing infinite families of rewrite rules where certain marked subgraphs, called !-boxes ("bang boxes", on both sides of a rule can be copied any number of times or removed. After reviewing the string graph formalism, we show how string graphs can be extended to pattern graphs and how pattern graphs and pattern rewrite rules can be instantiated to concrete string graphs and rewrite rules. We then provide examples demonstrating the expressive power of pattern graphs and how they can be applied to study interacting algebraic structures that are central to categorical quantum mechanics.

  6. Rewriting Modulo SMT and Open System Analysis

    Science.gov (United States)

    Rocha, Camilo; Meseguer, Jose; Munoz, Cesar

    2014-01-01

    This paper proposes rewriting modulo SMT, a new technique that combines the power of SMT solving, rewriting modulo theories, and model checking. Rewriting modulo SMT is ideally suited to model and analyze infinite-state open systems, i.e., systems that interact with a non-deterministic environment. Such systems exhibit both internal non-determinism, which is proper to the system, and external non-determinism, which is due to the environment. In a reflective formalism, such as rewriting logic, rewriting modulo SMT can be reduced to standard rewriting. Hence, rewriting modulo SMT naturally extends rewriting-based reachability analysis techniques, which are available for closed systems, to open systems. The proposed technique is illustrated with the formal analysis of: (i) a real-time system that is beyond the scope of timed-automata methods and (ii) automatic detection of reachability violations in a synchronous language developed to support autonomous spacecraft operations.

    East Antarctic Ice Sheet (EAIS) mass balance is largely driven by snowfall. Recently, increased snowfall in Queen Maud Land led to years of EAIS mass gain. It is difficult to determine whether these years of enhanced snowfall are anomalous or part of a longer-term trend, reducing our ability to assess the mitigating impact of snowfall on sea level rise. We determine that the recent snowfall increases in western Queen Maud Land (QML) are part of a long-term trend (+5.2 ± 3.7% decade-1) and are unprecedented over the past two millennia. Warming between 1998 and 2016 is significant and rapid (+1.1 ± 0.7°C decade-1). Using these observations, we determine that the current accumulation and temperature increases in QML from an ensemble of global climate simulations are too low, which suggests that projections of the QML contribution to sea level rise are potentially overestimated with a reduced mitigating impact of enhanced snowfall in a warming world.

  9. SLIM-MAUD - a computer based technique for human reliability assessment

    International Nuclear Information System (INIS)

    Embrey, D.E.

    1985-01-01

    The Success Likelihood Index Methodology (SLIM) is a widely applicable technique which can be used to assess human error probabilities in both proceduralized and cognitive tasks (i.e. those involving decision making, problem solving, etc.). It assumes that expert assessors are able to evaluate the relative importance (or weights) of different factors called Performance Shaping Factors (PSFs), in determining the likelihood of error for the situations being assessed. Typical PSFs are the extent to which good procedures are available, operators are adequately trained, the man-machine interface is well designed, etc. If numerical ratings are made of the PSFs for the specific tasks being evaluated, these can be combined with the weights to give a numerical index, called the Success Likelihood Index (SLI). The SLI represents, in numerical form, the overall assessment of the experts of the likelihood of task success. The SLI can be subsequently transformed to a corresponding human error probability (HEP) estimate. The latest form of the SLIM technique is implemented using a microcomputer based system called MAUD (Multi-Attribute Utility Decomposition), the resulting technique being called SLIM-MAUD. A detailed description of the SLIM-MAUD technique and case studies of applications are available. An illustrative example of the application of SLIM-MAUD in probabilistic risk assessment is given

    2012-01-01

    The effect of interaction between liquid crystal (LC) and photoalignment material on the speed of optical rewriting process is investigated. The theoretical analysis shows that a smaller frank elastic constant K 22 of liquid crystal corresponds to a larger twist angle, which gives rise to a larger rewriting speed. Six different LC cells with the same boundary conditions (one substrate is covered with rubbed polyimide (PI) and the other with photo sensitive rewritable sulfuric dye 1(SD1)) are tested experimentally under the same illumination intensity (450 nm, 80 mW/cm 2 ). The results demonstrate that with a suitable liquid crystal, the LC optical rewriting speed for e-paper application can be obviously improved. For two well known LC materials E7 (K 22 is larger) and 5CB (K 22 is smaller), they require 11 s and 6 s corresponding to change alignment direction for generating image information. (general)

    Most of the standard pleasant properties of term rewriting systems are undecidable; to wit: local confluence, confluence, normalization, termination, and completeness.

    2015-05-01

    Full Text Available The general form of safe recursion (or ramified recurrence can be expressed by an infinite graph rewrite system including unfolding graph rewrite rules introduced by Dal Lago, Martini and Zorzi, in which the size of every normal form by innermost rewriting is polynomially bounded. Every unfolding graph rewrite rule is precedence terminating in the sense of Middeldorp, Ohsaki and Zantema. Although precedence terminating infinite rewrite systems cover all the primitive recursive functions, in this paper we consider graph rewrite systems precedence terminating with argument separation, which form a subclass of precedence terminating graph rewrite systems. We show that for any precedence terminating infinite graph rewrite system G with a specific argument separation, both the runtime complexity of G and the size of every normal form in G can be polynomially bounded. As a corollary, we obtain an alternative proof of the original result by Dal Lago et al.

    The days of rewritable paper are coming, printers of the future will use water-jet paper. Although several kinds of rewritable paper have been reported, practical usage of them is rare. Herein, a new rewritable paper for ink-free printing is proposed and demonstrated successfully by using water as the sole trigger to switch hydrochromic dyes on solid media. Water-jet prints with various colours are achieved with a commercial desktop printer based on these hydrochromic rewritable papers. The prints can be erased and rewritten dozens of times with no significant loss in colour quality.

    Context-dependent rewrite rules are used in many areas of natural language and speech processing. Work in computational phonology has demonstrated that, given certain conditions, such rewrite rules can be represented as finite-state transducers (FSTs). We describe a new algorithm for compiling rewrite rules into FSTs. We show the algorithm to be simpler and more efficient than existing algorithms. Further, many of our applications demand the ability to compile weighted rules into weighted FST...

  3. Rewriting the language of creativity

    DEFF Research Database (Denmark)

    Glaveanu, Vlad Petre

    2013-01-01

    For the past 5 decades the psychology of creativity has been influenced by what is known as the 4 P's of creative expression: person, process, product, and press. This conceptual schema, initially proposed by Rhodes (1961), helped researchers structure their thinking about the phenomenon. However......, it also supported an individualistic, static, and oftentimes disjointed vision of creativity. The present article aims to rewrite this fundamental language of the discipline by using terms that explicitly endorse a systemic, contextual, and dynamic approach. The 5 A's framework—actor, action, artifact...

    We propose a modal logic tailored to describe graph transformations and discuss some of its properties. We focus on a particular class of graphs called termgraphs. They are first-order terms augmented with sharing and cycles. Termgraphs allow one to describe classical data-structures (possibly with pointers) such as doubly-linked lists, circular lists etc. We show how the proposed logic can faithfully describe (i) termgraphs as well as (ii) the application of a termgraph rewrite rule (i.e. ma...

As target contaminants 32 PCB congeners, α- and γ-hexachlorocyclohexane (HCH, trans- and cis-chlordane, trans- and cis-nonachlor, p,p'- and o,p-DDT, DDD, DDE as well as hexachlorobenzene (HCB were selected. The monitoring program with weekly samples taken during the period 2007–2010 was coordinated with the parallel program at the Norwegian Arctic monitoring site (Zeppelin mountain, Ny-Ålesund, Svalbard in terms of priority compounds, sampling schedule as well as analytical methods. The POP concentration levels found in Antarctica were considerably lower than Arctic atmospheric background concentrations. Similar to observations for Arctic samples, HCB is the predominant POP compound, with levels of around 22 pg m−3 throughout the entire monitoring period. In general, the following concentration distribution was found for the Troll samples analyzed: HCB > Sum HCH > Sum PCB > Sum DDT > Sum chlordanes. Atmospheric long-range transport was identified as a major contamination source for POPs in Antarctic environments. Several long-range transport events with elevated levels of pesticides and/or compounds with industrial sources were identified based on retroplume calculations with a Lagrangian particle dispersion model (FLEXPART.

    2002-01-01

    Vertical successions (>80 m thick) of the Permian Amelang Formation were studied in the southern Kirwannveggen, western Dronning Maud Land. Geochemical and petrographic results indicate that the dominant provenance of the formation was the Sverdrupfjella gneiss. A paleocurrent change in the formation and a difference in the clay mineralogy suggest the formation could be divided into two members. The thin coal seams have a rank of sub-bituminous B with associated maximum maturation temperatures of 80 degrees C. Palynological evindence indicates a Sakmarian (Early Permian) age for samples taken from immediately above the thickest coal seam. Sinusoidal trace fossils have a similar amplitude and wavelength to modern and Eocene Diptera traces, suggesting that traces which would normally be termed Cochlichnus may have been formed by Ceratopognid larvae.

  15. PVeStA: A Parallel Statistical Model Checking and Quantitative Analysis Tool

    KAUST Repository

    AlTurki, Musab

    2011-01-01

    Statistical model checking is an attractive formal analysis method for probabilistic systems such as, for example, cyber-physical systems which are often probabilistic in nature. This paper is about drastically increasing the scalability of statistical model checking, and making such scalability of analysis available to tools like Maude, where probabilistic systems can be specified at a high level as probabilistic rewrite theories. It presents PVeStA, an extension and parallelization of the VeStA statistical model checking tool [10]. PVeStA supports statistical model checking of probabilistic real-time systems specified as either: (i) discrete or continuous Markov Chains; or (ii) probabilistic rewrite theories in Maude. Furthermore, the properties that it can model check can be expressed in either: (i) PCTL/CSL, or (ii) the QuaTEx quantitative temporal logic. As our experiments show, the performance gains obtained from parallelization can be very high. © 2011 Springer-Verlag.

    2001-01-01

    We present recent work on the development Java PathExplorer (JPAX), a tool for monitoring the execution of Java programs. JPAX can be used during program testing to gain increased information about program executions, and can potentially furthermore be applied during operation to survey safety critical systems. The tool facilitates automated instrumentation of a program's late code which will then omit events to an observer during its execution. The observer checks the events against user provided high level requirement specifications, for example temporal logic formulae, and against lower level error detection procedures, for example concurrency related such as deadlock and data race algorithms. High level requirement specifications together with their underlying logics are defined in the Maude rewriting logic, and then can either be directly checked using the Maude rewriting engine, or be first translated to efficient data structures and then checked in Java.

    1986-10-01

    The US Nuclear Regulatory Commission (NRC) has been conducting a multiyear research program to investigate different methods for using expert judgments to estimate human error probabilities (HEPs) in nuclear power plants. One of the methods investigated, derived from multi-attribute utility theory, is the Success Likelihood Index Methodolocy implemented through Multi-Attribute Utility Decomposition (SLIM-MAUD). This report describes a systematic test application of the SLIM-MAUD methodology. The test application is evaluated on the basis of three criteria: practicality, acceptability, and usefulness. Volume I of this report represents an overview of SLIM-MAUD, describes the procedures followed in the test application, and provides a summary of the results obtained. Volume II consists of technical appendices to support in detail the materials contained in Volume I, and the users' package of explicit procedures to be followed in implementing SLIM-MAUD. The results obtained in the test application provide support for the application of SLIM-MAUD to a wide variety of applications requiring estimates of human errors

    2014-07-01

    Full Text Available We present strategic portgraph rewriting as a basis for the implementation of visual modelling and analysis tools. The goal is to facilitate the specification, analysis and simulation of complex systems, using port graphs. A system is represented by an initial graph and a collection of graph rewriting rules, together with a user-defined strategy to control the application of rules. The strategy language includes constructs to deal with graph traversal and management of rewriting positions in the graph. We give a small-step operational semantics for the language, and describe its implementation in the graph transformation and visualisation tool PORGY.

    We answer an open question related to bisimilarity checking on labelled transition systems generated by prefix rewrite rules on words. Stirling (1996, 1998) proved the decidability of bisimilarity for normed pushdown processes. This result was substantially extended by Senizergues (1998, 2005) who...... language) was left open; this was repeatedly indicated by both Stirling and Senizergues. Here we answer the question negatively, i.e., we show undecidability of bisimilarity on Type -1 systems, even in the normed case. We complete the picture by considering classes of systems that use rewrite rules...

    In this dissertation we investigate two independent areas of research. In the first part, we develop techniques for implementing programming languages in a modular fashion. Within this problem domain, we focus on operations on typed abstract syntax trees with the goal of developing a framework...... that facilitates the definition, manipulation and composition of such operations. The result of our work is a comprehensive combinator library that provides these facilities. What sets our approach apart is the use of recursion schemes derived from tree automata in order to implement operations on abstract syntax...... trees. The second part is concerned with infinitary rewriting, a field that studies transfinite rewrite sequences. We extend the established theory of infinitary rewriting in two ways: (1) a novel approach to convergence in infinitary rewriting that replaces convergence in a metric space with the limit...

    Emma Maud McCarthy was one of the most decorated nurses of the First World War. Born in Sydney in 1859, she trained as a nurse at The London Hospital in England. She was one of the first nurses to go to the South African War and in 1914 was one of the first members of Queen Alexandra's Imperial Nursing Service. Maud McCarthy went to France as Matron-in-Chief of British, Colonial and US nursing services until the end of hostilities in 1918. After the First World War she became Matron-in-Chief of the Territorial Army Nursing Service and retired five years later. She was appointed Dame Grand Cross in 1918 and earned awards from Britain, France, Belgium and America. Her influence on nursing was profound. One of the first senior nurses to recognise the impact of war on minds, she set up separate units for men who had self-harmed and she pioneered nurse anaesthetists in the British Armed Forces. Dame Maud McCarthy was an administrator par excellence whose determination to provide the best conditions possible for both her nurses and the men for whom they cared made possible the highest standards of nursing care in the First World War. © The Author(s) 2015.

    It is very difficult to make a liquid crystal display (LCD) that is flexible. However, for an optically re-writable LCD (ORWLCD), only the spacers and the substrates need to be flexible because the driving unit and the display unit are separate and there are no electronics in the display part of ORWLCD. In this paper, three flexible-spacer methods are proposed to achieve this goal. A cholesteric liquid crystal colored mirror with a polarizer behind it is used as the colored reflective backboard of an ORWLCD. Polyethersulfone substrates and flexible spacers are used to make the optically re-writable cell insensitive to mechanical force.

    International Nuclear Information System (INIS)

    2008-01-01

    The Nilpotent Universal Computer Rewrite System (NUCRS) has operationalized the radical ontological dilemma of Nothing at All versus Anything at All down to the ground recursive syntax and principal mathematical realisation of this categorical dichotomy as such and so governing all its sui generis modalities, leading to fulfilment of their individual terms and compass when the respective choice sequence operations are brought to closure. Focussing on the general grammar, NUCRS by pure logic and its algebraic notations hence bootstraps Quantum Mechanics, aware that it ''is the likely keystone of a fundamental computational foundation'' also for e.g. physics, molecular biology and neuroscience. The present work deals with classical geometry where morphology is the modality, and ventures that the ancient regular solids are its specific rewrite system, in effect extensively anticipating the detailed elementary particle spectroscopy, and further on to essential structures at large both over the inorganic and organic realms. The geodetic antipode to Nothing is extension, with natural eigenvector the endless straight line which when deployed according to the NUCRS as well as Plotelemeian topographic prescriptions forms a real three-dimensional eigenspace with cubical eigenelements where observed quark-skewed quantum-chromodynamical particle events self-generate as an Aristotelean phase transition between the straight and round extremes of absolute endlessness under the symmetry- and gauge-preserving, canonical coset decomposition SO(3)xO(5) of Lie algebra SU(3). The cubical eigen-space and eigen-elements are the parental state and frame, and the other solids are a range of transition matrix elements and portions adapting to the spherical root vector symmetries and so reproducibly reproducing the elementary particle spectroscopy, including a modular, truncated octahedron nano-composition of the Electron which piecemeal enter into molecular structures or compressed to each

    dykes of the Schirmacher Oasis and basalts and dolerites of the Queen Maud Land (180 Ma) are identical in petrology and geochemistry terms and supposedly could be interpreted as the manifestation of the Karoo-Maud plume activity in Antarctica [Sushchevskaya et al., 2012]. The spatial distribution of the dikes indicates the eastward spreading of the plume material from DML to the Schirmacher Oasis within at least 10 Ma (up to ~35 Ma, taking into account the uncertainty of age determination). On the other hand, the considerable duration and multistage character of plume magmatism related to the activity of the Karoo-Maud plume in Antarctica and Africa [Leat et al., 2007; Luttinen et al., 2002] may indicate that the Mesozoic dikes of the oasis correspond to a single stage of plume magmatism. On the basis of obtained isotopic data it has been determined two magmatic melt evolution trends for basalts from: Queen Maud Land - Kerguelen Archipelago - Afanasy Nikitin Rise (Indian Ocean) and Jetty - Schirmacher oasises which mantle sources are quite different. Thus the Jetty - Schirmacher oasises magmatic melt sources are characterized by prevalence of the matter of moderately enriched or primitive chondritic mantle source and lithospheric mantle of Proterozoic ages but the substances of depleted mantle source similar to MORB-type and ancient mantle are absent. New data obtained on Nd, Sr, Pb isotopic and lithophile elements compositions of the alkaline-ultrabasic rocks from the Jetty oasis and Gaussberg volcano completed imagine of the Kerguelen-plume evolution. It has been confirmed unique character of the alkaline lamproiites of the Gaussberg volcano enrichments. Highly radiogenic Sr and Pb isotope ratios of these lamproiites reflect melting of the ancient sublithospheric depleted mantle which was stored from the Archean till nowadays unaffected by metasomatic-enrichment processes. During modern melting of this mantle part there is input of additional substances (crustal fluid

    We describe the first DNA-based storage architecture that enables random access to data blocks and rewriting of information stored at arbitrary locations within the blocks. The newly developed architecture overcomes drawbacks of existing read-only methods that require decoding the whole file in order to read one data fragment. Our system is based on new constrained coding techniques and accompanying DNA editing methods that ensure data reliability, specificity and sensitivity of access, and at the same time provide exceptionally high data storage capacity. As a proof of concept, we encoded parts of the Wikipedia pages of six universities in the USA, and selected and edited parts of the text written in DNA corresponding to three of these schools. The results suggest that DNA is a versatile media suitable for both ultrahigh density archival and rewritable storage applications.

    A series of lava flows from Mountain B (6 0 13.9'W, 74 0 06.9'S) of the Kirwan Escarpment in Dronning Maud Land, Antarctica, is composed of tholeiite basalts of Jurassic age. Their chemical compositions are similar to those of Jurassic basalts elsewhere in Dronning Maud Land but differ from those of the Kirkpatrick Basalt of the Transantarctic Mountains. The basalts on Mountain B contain 50.39% SiO 2 , 9.7 ppm Rb, 174.4 ppm Sr, have a Rb/Sr ratio of 0.057, and a K/Rb ratio of 417. Their average initial 87 Sr/ 86 Sr ratio is 0.7044 +- 0.0010 (1sigma) which suggests that the magma from which they formed could have been derived from the upper mantle without extensive contamination with 87 Sr and other elements. These results confirm earlier suggestions that the Jurassic basalts of Dronning Maud Land differ significantly from the Kirkpatrick Basalt and the Ferrar Dolerite of the Transantarctic Mountains. These differences in chemical and Sr-isotopic composition may be related to tectonic activity and magma formation during the break-up of Gondwanaland. (Auth.)

    We succeeded in recording and observing femtosecond light pulse propagation as a form of moving picture by means of light-in-flight recording by holography using a rewritable holographic material, for the first time. We used a femtosecond pulsed laser whose center wavelength and duration were 800 nm and {approx}120 fs, respectively. A photo-conductor plastic hologram was used as a rewritable holographic material. The femtosecond light pulse was collimated and obliquely incident to the diffuser plate. The behavior of the cross-section between the collimated femtosecond light pulse and the diffuser plate was recorded on the photo-conductor plastic hologram. We experimentally obtained a spatially and temporally continuous moving picture of the femtosecond light pulse propagation for 58.3 ps. Meanwhile, we also investigated the rewritable performance of the photo-conductor plastic hologram. As a result, we confirmed that ten-time rewriting was possible for a photo-conductor plastic hologram.

    Structural colors (SCs) of photonic crystals (PCs) arise from selective constructive interference of incident light. Here, an ink-jet printable and rewritable block copolymer (BCP) SC display is demonstrated, which can be quickly written and erased over 50 times with resolution nearly equivalent to that obtained with a commercial office ink-jet printer. Moreover, the writing process employs an easily modified printer for position- and concentration-controlled deposition of a single, colorless, water-based ink containing a reversible crosslinking agent, ammonium persulfate. Deposition of the ink onto a self-assembled BCP PC film comprising a 1D stack of alternating layers enables differential swelling of the written BCP film and produces a full-colored SC display of characters and images. Furthermore, the information can be readily erased and the system can be reset by application of hydrogen bromide. Subsequently, new information can be rewritten, resulting in a chemically rewritable BCP SC display. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2011-01-01

    This paper explores Maude Abbott's internationally significant career in medicine and her parallel commitment to caring for her sister, Alice Abbott. An examination of Abbott's life reveals the difficulties faced by an ambitious Canadian woman in medicine from the 1890s to the 1920s; difficulties compounded by caring for a sister with a mental illness. The Abbott archive suggests that it was far more difficult for a woman doctor to make the kind of sharp distinction between public and private life that might be expected of professional men.

    We report the development of on-chip fluorescence switching system based on DNA strand displacement and DNA hybridization for the construction of a rewritable and randomly accessible data storage device. In this study, the feasibility and potential effectiveness of our proposed system was evaluated with a series of wet experiments involving 40 bits (5 bytes) of data encoding a 5-charactered text (KRIBB). Also, a flexible data rewriting function was achieved by converting fluorescence signals between "ON" and "OFF" through DNA strand displacement and hybridization events. In addition, the proposed system was successfully validated on a microfluidic chip which could further facilitate the encoding and decoding process of data. To the best of our knowledge, this is the first report on the use of DNA hybridization and DNA strand displacement in the field of data storage devices. Taken together, our results demonstrated that DNA-based fluorescence switching could be applicable to construct a rewritable and randomly accessible data storage device through controllable DNA manipulations.

    Zamanali, J.H.; Hubbard, F.R.; Mosleh, A.; Waller, M.A.

    1992-01-01

    The methodology described in this paper assigns plant-specific dynamic human error rates (HERs) for individual plant examinations based on procedural difficulty, on configuration features, and on the time available to perform the action. This methodology is an evolutionary improvement of the success likelihood index methodology (SLIM-MAUD) for use in systemic scenarios. It is based on the assumption that the HER in a particular situation depends of the combined effects of a comprehensive set of performance-shaping factors (PSFs) that influence the operator's ability to perform the action successfully. The PSFs relate the details of the systemic scenario in which the action must be performed according to the operator's psychological and cognitive condition

    2004-10-01

    A new rewritable printing media using electrophoresis and selective heating is proposed to contribute to the reduction in paper consumption by printers. The mechanism is that when a heated part of the rewritable media is melted, white particles in that part of the media are able to move by electrophoresis. The media is initialized by heating its entire surface under the condition of voltage application and imaging is carried out by selective heating under the condition of an applied reversed-polarity voltage. Using a mixture system of carnauba wax and particles coated with titanium oxide (TiO2), the feasibility of the mechanism is confirmed.

    This paper describes Grrr, a prototype visual graph drawing tool. Previously there were no visual languages for programming graph drawing algorithms despite the inherently visual nature of the process. The languages which gave a diagrammatic view of graphs were not computationally complete and so could not be used to implement complex graph drawing algorithms. Hence current graph drawing tools are all text based. Recent developments in graph rewriting systems have produced computationally com...

  14. Testing Linear Temporal Logic Formulae on Finite Execution Traces

    Science.gov (United States)

    Havelund, Klaus; Rosu, Grigore; Norvig, Peter (Technical Monitor)

    2001-01-01

    We present an algorithm for efficiently testing Linear Temporal Logic (LTL) formulae on finite execution traces. The standard models of LTL are infinite traces, reflecting the behavior of reactive and concurrent systems which conceptually may be continuously alive. In most past applications of LTL. theorem provers and model checkers have been used to formally prove that down-scaled models satisfy such LTL specifications. Our goal is instead to use LTL for up-scaled testing of real software applications. Such tests correspond to analyzing the conformance of finite traces against LTL formulae. We first describe what it means for a finite trace to satisfy an LTL property. We then suggest an optimized algorithm based on transforming LTL formulae. The work is done using the Maude rewriting system. which turns out to provide a perfect notation and an efficient rewriting engine for performing these experiments.

    We analyze the structure of Te-based chalcogenide compounds that are used as materials for rewritable DVDs by using a combination of neutron diffraction and ab initio computer simulation. We show that in the liquid, the atoms have a low average coordination number, as the result of a Peierls distortion. The partial pair correlation functions are obtained from the computer simulation data.

  6. Incremental Query Rewriting with Resolution

    Science.gov (United States)

    Riazanov, Alexandre; Aragão, Marcelo A. T.

    We address the problem of semantic querying of relational databases (RDB) modulo knowledge bases using very expressive knowledge representation formalisms, such as full first-order logic or its various fragments. We propose to use a resolution-based first-order logic (FOL) reasoner for computing schematic answers to deductive queries, with the subsequent translation of these schematic answers to SQL queries which are evaluated using a conventional relational DBMS. We call our method incremental query rewriting, because an original semantic query is rewritten into a (potentially infinite) series of SQL queries. In this chapter, we outline the main idea of our technique - using abstractions of databases and constrained clauses for deriving schematic answers, and provide completeness and soundness proofs to justify the applicability of this technique to the case of resolution for FOL without equality. The proposed method can be directly used with regular RDBs, including legacy databases. Moreover, we propose it as a potential basis for an efficient Web-scale semantic search technology.

    Kalff, Floris; Rebergen, Marnix; Fahrenfort, Nora; Girovsky, Jan; Toskovic, Ranko; Lado, Jose; FernáNdez-Rossier, JoaquíN.; Otte, Sander

    The ability to manipulate individual atoms by means of scanning tunneling microscopy (STM) opens op opportunities for storage of digital data on the atomic scale. Recent achievements in this direction include data storage based on bits encoded in the charge state, the magnetic state, or the local presence of single atoms or atomic assemblies. However, a key challenge at this stage is the extension of such technologies into large-scale rewritable bit arrays. We demonstrate a digital atomic-scale memory of up to 1 kilobyte (8000 bits) using an array of individual surface vacancies in a chlorine terminated Cu(100) surface. The chlorine vacancies are found to be stable at temperatures up to 77 K. The memory, crafted using scanning tunneling microscopy at low temperature, can be read and re-written automatically by means of atomic-scale markers, and offers an areal density of 502 Terabits per square inch, outperforming state-of-the-art hard disk drives by three orders of magnitude.

  10. Concept of rewritable organic ferroelectric random access memory in two lateral transistors-in-one cell architecture

    International Nuclear Information System (INIS)

    Kim, Min-Hoi; Lee, Gyu Jeong; Keum, Chang-Min; Lee, Sin-Doo

    2014-01-01

    We propose a concept of rewritable ferroelectric random access memory (RAM) with two lateral organic transistors-in-one cell architecture. Lateral integration of a paraelectric organic field-effect transistor (OFET), being a selection transistor, and a ferroelectric OFET as a memory transistor is realized using a paraelectric depolarizing layer (PDL) which is patterned on a ferroelectric insulator by transfer-printing. For the selection transistor, the key roles of the PDL are to reduce the dipolar strength and the surface roughness of the gate insulator, leading to the low memory on–off ratio and the high switching on–off current ratio. A new driving scheme preventing the crosstalk between adjacent memory cells is also demonstrated for the rewritable operation of the ferroelectric RAM. (paper)

    Directory of Open Access Journals (Sweden)

    Sanna Lehtonen

    2010-01-01

    Full Text Available The attempts to challenge conventional gendered discourses in children's fantasy have often resulted in feminist rewritings of earlier stories. Ghost dance (1994 by the English author Susan Price is a novel that reflects a specific feminist poetics of rewriting: metafictional passages highlight the constructedness of the narrative and at the end readers are invited to tell their own versions of the story. Moreover, the rewriting freely combines and recontextualises elements from different source texts and reformulates them to create a narrative that challenges conventional discourses of gender. While this poetics has an appeal from a feminist perspective, the play with cross-cultural intertexts and gender becomes more complex when the novel is examined in a postcolonialist framework in relation to ethnicity and the issue of cultural appropriation. Ghost dance is situated in a setting that has a real-world equivalent (Russia, involves characters that are identified with names of real-world ethnic groups (Lapps (Sámi, Russian, and mixes elements from Russian wonder tales, Nordic mythology and an Ojibwe legend. The novel does not aim at historical accuracy in its representations nor is it a direct retelling of any of the pre-texts but combines motifs, themes, names, characters and settings freely from each source. In this textual melting pot, the protagonist Shingebiss is, on one level, a revision of the witch Baba Yaga, but also described as a Lappish shaman with an Ojibwe name. To rewrite gendered discourses, certain elements from the pretexts are chosen and others left out – the question is, then, what effects does this recontextualisation have on the representation of ethnicity? Or, are the feminist rewriting strategies actually a form of cultural appropriation?

    Science.gov (United States)

    Schwanke, Joerg; Megnet, Roland; Jensch, Peter F.

    1993-03-01

    The automation of plant-micropropagation is necessary to produce high amounts of biomass. Plants have to be dissected on particular cutting-points. A vision-system is needed for the recognition of the cutting-points on the plants. With this background, this contribution is directed to the underlying formalism to determine cutting-points on abstract-plant models. We show the usefulness of pattern recognition by graph-rewriting along with some examples in this context.

    International Nuclear Information System (INIS)

    Wand, U.; Muehle, K.

    1988-01-01

    In order to estimate the peak metamorphic temperatures in high-grade regional metamorphic marbles from central Dronning Maud Land (East Antarctica), 13 C/ 12 C isotope ratios have been measured for coexisting carbonate and graphite pairs. The δ 13 C values of carbonates (calcite ± dolomite) and graphite vary from -0.1 to +4.6 permill (PDB) and from -3.3 to +1.7 permill, respectively. The isotopic fractionation between carbonate and graphite ranges from 2.9 to 4.0 permill and is similar to the Δ 13 C (carb-gr) values observed in other East Antarctic and non-Antarctic granulite-facies marbles. The metamorphic temperatures calculated using the equation of VALLEY and O'NEIL (1981) for calcite-graphite pairs are predominantly in the range 700 0 - 800 0 C (x n=5 ± s = 730 0 ± 30 0 C) and agree well with metamorphic temperatures derived from mineral chemical studies in this East Antarctic region.

    Mamyu rock specimens, were collected from the sor-rondane mountains and Breid Bay area of Drojnning Maud land, eastern Antarctica, during the 2nd Pakistan Antarctic Expedition, 1992-93. Petrography and geochemical studies suggest that the rocks are essentially of igneous origin. The samples dredged from ocean bottom include olivine basalt, amygdaloidal volcanics, dacites and rhyodacites. A majority of these rocks are calc-alkaline and formed by the fraction of olivine, clinopyroxene and plagioclase +- titanomagnetite. Most of these rocks apparently formed in an island arc or continental margin set up. However, volcanics showing ocean floor basalt character are also present. A metamorphosed and deformed basement consisting of amphibolites, calc-silicate rocks and gneisses is intrude by under formed or only slightly deformed granites with a minor arkosic sandstone cover. The granites are chemically distinguished as I-type, originate at deeper crystal level by collisional/subduction related processes during organic environments. (author)

  16. Good grief: Lord of the Flies as a post-war rewriting of salvation history

    Directory of Open Access Journals (Sweden)

    M. van Vuuren

    2004-07-01

    Full Text Available Golding’s Lord of the Flies, first published in 1954, reflects a bleak sense of post-war pessimism. But with undue attention focused on its portrayal of original sin and the problem of evil, readings have often remained reductive. In this article it is argued that the novel’s symbolic narrative is polysemic and, when it is read as anagogic myth, may be seen to span Judaeo-Christian Heilsgeschichte or salvation history, rewriting its chapters of creation, Fall, the problem of evil, the failure of law, the hope of salvation, the mission of a messianic figure, and – in the clearest departure from the Biblical narrative – an ambiguous representation of his return. This study examines the novel’s often paradoxical symbolism using Frye’s phases of anagogic myth, with its poles of apocalyptic and demonic imagery. It traces the relation of symbols to their counterparts in Biblical narratives, drawn in particular from the symbolic writings of the origin and end of humanity, to elucidate Golding’s bleak but certainly not hopeless rewriting of the salvation story for a post-faith readership.

  17. Characteristic Seismic Waves Associated with Cryosphere Dynamics in Eastern Dronning Maud Land, East Antarctica

    Full Text Available Several kinds of natural source signals are recorded by seismic exploration stations on the continental ice sheet in Eastern Dronning Maud Land, East Antarctica, during 2002 austral summer. They include not only tectonic earthquakes, but also ice-related phenomena possibly involving recent global climate change. The recorded signals are classified into (1 teleseismic events, (2 local ice quakes, and (3 unidentified events (X-phases. The teleseismic waves show the high signal-to-noise ratio in spite of the small magnitude of the event; this indicates that it is highly feasible to study not only the local shallow structure but also the deep structure of the earth by using teleseismic events. Frequency spectra of the all waveforms represent discordances along the observation seismic profile. The abrupt change of topography in the valley along the seismic profile might cause both the anomalous frequency content and travel times. Finally, an origin of the X-phases is speculated as the intraplate earthquakes or possibly large ice-quakes (glacial earthquakes around Antarctica, involving global warming appeared in polar region.

    An electrically bistable device utilizing a nanocomposite of hexadecylamine-functionalized graphene oxide (HDAGO) with poly(3-hexylthiophene) (P3HT) is demonstrated. The device has an ITO/P3HT-HDAGO/Al sandwich structure, in which the composite film of P3HT-HDAGO was prepared by simple solution phase mixing of the exfoliated HDAGO monolayers with P3HT matrix and a spin-coating method. The memory device exhibits typical bistable electrical switching behavior and a nonvolatile rewritable memory effect, with a turn-on voltage of about 1.5 V and an ON/OFF-state current ratio of 10{sup 5}. Under ambient conditions, both the ON and OFF states are stable under a constant voltage stress or a continuous pulse voltage stress at a read voltage of 1 V. The conduction mechanism is deduced from the modeling of the nature of currents in both states, and the electrical switching behavior can be attributed to the electric-field-induced charge transfer between P3HT and HDAGO nanosheets. - Highlights: • Nonvolatile rewritable memory effect in P3HT–graphene composite is demonstrated. • The memory device was fabricated through a simple solution processing technique. • The device shows a remarkable electrical bistable behavior and excellent stability. • Memory mechanism is deduced from the modeling of the currents in both states.

    Aspects of the geology and geochemistry of the layered rocks at Annandagstoppane (72 degrees 33'S, 06 degrees 16'W) and Juletoppane (72 degrees 23'S, 05 degrees 33'W) in the Giaeverryggen, western Dronning Maud Land, are discussed. The mafic rocks in the two areas have been divided into a 'main suite' and a 'younger suite'. The main suite rocks comprise medium-grained gabbros, gabbronorites and anorhositic gabbros. lenticular and discontinuous rhythmic layers are present. The younger suite comprises basaltic dykes at Annandagstoppane, and a dolerite sill and small pods of fine-grained gabbroic bodies at Juletoppane. Petrographic and geochemical aspects of main suite rocks in the two areas show close similarities, and indicate that pyroxene and plagioclase were the primocrysts in the orthocumulate assemblages. The preliminary results suggest that the Annandagstoppane and Juletoppane gabbroic rocks may either constitute a single layered intrusion, or reflect outcrops of intrusions of several ages, their magmas having been derived from compositionally similar mantle sources. The close chemical similarities of the younger suite with the main suite suggest that all the mafic phases in the two areas are genetically related

    Rapidly responsive and flexible photonic papers are manufactured by coassembly of cellulose nanocrystals (CNCs) and waterborne polyurethane (WPU) latex for fully taking advantage of the chiral nematic structure of CNCs and the flexibility of WPU elastomer. The resulting CNC/WPU composite papers exhibit not only tunable iridescent colors by adjusting the helical pitch size, but also instant optical responses to water and wet gas, ascribed to the easy chain movement of the elastomeric WPU that does not restrict the fast water absorption-induced swelling of CNCs. By choosing water or NaCl aqueous solutions as inks, the colorful patterns on the CNC/WPU photonic paper can be made temporary, durable, or even disguisable. In addition, the photonic paper is simultaneously rewritable for all these three types of patterns, and the disguisable patterns, which are invisible at normal times and show up under stimuli, exhibit a quick reveal conversion just by exhaling on the paper. The rewritability, rapid responsibility, easy fabrication, and the eco-friendly nature of the inks make the flexible photonic paper/ink combination highly promising in sensors, displays, and photonic circuits.

  3. The Politics of Rewriting History: New History Textbooks and Curriculum Materials in Russia

    2003-07-01

    The collapse of communism in Russia in 1991 necessitated, among other things, the rewriting of school history textbooks, which had been dominated by Marxist-Leninist interpretations of historical events. The aim of this article is to evaluate the new postcommunist history taught in upper secondary schools, giving particular attention to how the models for Russian identity presented in the new textbooks redefine legitimate culture for students. Attention will also be given to the multiple perspectives on history that textbooks and other curriculum materials emphasize; these new methods contrast with the grand narrative that dominated the study of history before 1991.

  4. SPARQL Query Re-writing Using Partonomy Based Transformation Rules

    Jain, Prateek; Yeh, Peter Z.; Verma, Kunal; Henson, Cory A.; Sheth, Amit P.

    Often the information present in a spatial knowledge base is represented at a different level of granularity and abstraction than the query constraints. For querying ontology's containing spatial information, the precise relationships between spatial entities has to be specified in the basic graph pattern of SPARQL query which can result in long and complex queries. We present a novel approach to help users intuitively write SPARQL queries to query spatial data, rather than relying on knowledge of the ontology structure. Our framework re-writes queries, using transformation rules to exploit part-whole relations between geographical entities to address the mismatches between query constraints and knowledge base. Our experiments were performed on completely third party datasets and queries. Evaluations were performed on Geonames dataset using questions from National Geographic Bee serialized into SPARQL and British Administrative Geography Ontology using questions from a popular trivia website. These experiments demonstrate high precision in retrieval of results and ease in writing queries.

    The development of nanostructures that can be reversibly arranged and assembled into 3D patterns may enable optical tunability. However, current dynamic recording materials such as photorefractive polymers cannot be used to store information permanently while also retaining configurability. Here, we describe the synthesis and optimization of a silver nanoparticle doped poly(2-hydroxyethyl methacrylate-co-methacrylic acid) recording medium for reversibly recording 3D holograms. We theoretically and experimentally demonstrate organizing nanoparticles into 3D assemblies in the recording medium using optical forces produced by the gradients of standing waves. The nanoparticles in the recording medium are organized by multiple nanosecond laser pulses to produce reconfigurable slanted multilayer structures. We demonstrate the capability of producing rewritable optical elements such as multilayer Bragg diffraction gratings, 1D photonic crystals, and 3D multiplexed optical gratings. We also show that 3D virtual holograms can be reversibly recorded. This recording strategy may have applications in reconfigurable optical elements, data storage devices, and dynamic holographic displays.

    2012-06-01

    Full Text Available This article focuses on Laura Esquivel’s Like Water for Chocolate and reads the novel using the literary theories of the “new mestiza,” postcolonial theories, feminist theories, and historiographic metafiction. It seeks to find out how this novel rewrites the female experience of the Mexican Revolution, and the various techniques used in the rewriting of history. It reads the novel from a “new mestiza” feminist perspective, which enables the Filipina reader to find commonalities in the Mexican woman’s struggle in Mexican history and society, and finds ways to help her appreciate the Filipina’s struggle in Philippine history and society. The theories of historiographic metafiction are grounded in Linda Hutcheon’s theories about historiography, or the writing of history, and metafiction, or fiction that makes us aware of the craft of fiction. The theories regarding the “new mestiza” consciousness are from Gloria Anzaldua. This is a feminist theory that is contextualized on the historic oppression of women during Spanish colonization and its resulting patriarchal structures in society, and how women can seek to free themselves from such residual structures. Finally, the article touches upon a Filipina feminist perspective on the novel and what it signifies for the Philippine female experience.

    Terrestrial cosmogenic nuclide exposure ages for the Wohlthat Massif (Antarctica), have previously been determined. This was done with {sup 10}Be and {sup 26}Al measurements by accelerator mass spectrometry (AMS) at the AMS facility at the ETH Zurich. In order to determine the extent to which the results from the Wohlthat Massif are of regional significance, additional samples were collected during the 2007 BGR-expedition “Queenmet”. Two of the Steingarden Nunataks (isolated mountain peaks) were chosen as sampling locations, approximately 100 km south-east of the Wohlthat Massif/Queen Maud Land, at the edge of the Polar Plateau. Quartz rich samples were collected at different elevations on the nunataks to reconstruct an elevation-dependent exposure history. The in situ produced cosmogenic nuclides {sup 10}Be and {sup 26}Al in these samples were measured by AMS. During sample processing the quartz separates were prepared by two different methods (Kohl and Nishiizumi, 1992, Altmaier, 2000) and measurements were performed at two different facilities (CologneAMS und Zurich AMS) to confirm the reproducibility of the results. The new results of rock surface exposure ages reveal that the exposure of the lower nunatak to cosmic radiation started between 0.65 and 1.1 Ma ago, while the more elevated regions of the second nunatak were apparently above the ice 3–4 Ma ago.

    Full Text Available In The City of Ladies and Bell in Campo, Christine de Pizan and Margaret Cavendish imagine women’s participation to war as a metaphor of the sexual conflict that they must fight in order to conquer their visibility in history. While Pizan rewrites history from women’s stand point and acknowledges the universal value of sexual difference for the plan of salvation, Cavendish moves within a modern frame and thinks history as the result of human action. In both cases, the tale of women’s participation to war allows criticizing the moral and normative implications of «nature».

  10. Laser writing and rewriting on YBa2Cu3O7 films

    1991-01-01

    High-resolution patterning (4 μm) has been achieved on epitaxial thin films of the high-temperature superconductor YBa 2 Cu 3 O 7-δ using laser writing. A focused laser beam is applied to write semiconducting patterns on superconducting films in a vacuum or in a nitrogen atmosphere. The semiconducting patterns are shown to be formed by a reduction of the oxygen content due to local heating caused by the laser beam. The process does not cause any structural damage and does not change the surface morphology. When reapplying the same laser beam and rewriting the film in an oxygen atmosphere, it is possible to restore the superconductive properties. The application of this method for production of superconducting microelectronic circuits is discussed

  11. The Lacanian Concept of Cut in Light of Lacan's Interactions with Maud Mannoni

    Directory of Open Access Journals (Sweden)

    Laure Razon

    2017-12-01

    Full Text Available This article sets out to shed light on the Lacanian concept of cut (introduced in 1961–1962: it refers to the symbolic (i.e., linguistic operation which produces the object a and thereby enables separation, through which the subject emerges. To that effect, we show how this concept benefitted from Lacan's interactions with Maud Mannoni (1923-1998, who focused on clinical situations where implementing a cut in the subject's environment is the only way to enable a separation between the child and the Other. Lacan first drew on Mannoni's clinical elaborations about the retarded child's alienation to the maternal fantasy: when the mother's unconscious doesn't leave room for the cut, it prevents the separation through which the child could become a subject. Lacan generalized this in the late 1960s: he broadened Mannoni's alienation to the maternal fantasy to characterize a type of child symptom, where children become their mother's non-separated, de-phallicized object a. Then, in the 1970s, Mannoni proposed an original theoretico-clinical setting to address the configurations where the object a isn't separated: in the splintered institution, the team follows on projects of activities (professional, personal, etc. outside the institution voiced by children who haven't previously encountered the symbolic cut, by helping them realize these external projects. By thus acknowledging their attempts at establishing a cut and giving them consistency, the splintered institution helps them psychically elaborate separation.

    Phase-change materials based on chalcogenide alloys have been widely used for optical data storage and are promising materials for nonvolatile electrical memory use. However, the mechanism behind the utilization is unclear as yet. Since the rewritable data storage involved an extremely fast laser melt-quenched process for chalcogenide alloys, the liquid structure of which is one key to investigating the mechanism of the fast reversible phase transition and hence rewritable data storage, here by means of ab initio molecular dynamics we have studied the local structure of liquid Ge{sub 1}Sb{sub 2}Te{sub 4}. The results show that the liquid structure gives a picture of most Sb atoms being octahedrally coordinated, and the coexistence of tetrahedral and fivefold coordination at octahedral sites for Ge atoms, while Te atoms are essentially fourfold and threefold coordinated at octahedral sites, as characterized by partial pair correlation functions and bond angle distributions. The local structure of liquid Ge{sub 1}Sb{sub 2}Te{sub 4} generally resembles that of the crystalline form, except for the much lower coordination number. It may be this unique liquid structure that results in the fast and reversible phase transition between crystalline and amorphous states.

    Full Text Available Abstract For several years children at Joyce Public School have been rewriting traditional stories from localized cultural and linguistic perspectives, creating innovative, individualized narrative forms with digital technology. Our experimental multiliteracies research project is a collaboration of school and university teachers and researchers following a guided action research paradigm. The study has as one of its stated objectives the development of multilingual story retelling as a means of inexpensively supporting home language maintenance, fostering language awareness and aiding English as a second language learning in a community of high linguistic diversity. This paper tells our story thus far, focusing on how we have approached the creation of multilingual stories in heterogeneous, urban language classes, discussing stumbling blocks that have forced creative problem-solving and showcasing successes.

  15. Oxygen isotope variability in snow from western Dronning Maud Land, Antarctica and its relation to temperature

    This paper presents (delta) 18 O records from snow pits from four locations in Dronning Maud Land, Antarctica that contain at least four annual cycles. The aim of the study was to analyse in detail these records as well as the prevailing temperatures during accumulation in order to infer to what extent isotopic composition in this area can be interpreted as temperature information. The original seasonal amplitudes of the isotope records were reconstructed by use of a simple back-diffusion model. Automatic weather station data were used to describe the accumulation history and the near-surface temperatures; the temperatures at the atmospheric level of snow formation were inferred from a regional climate model. The results show that the strongly intermittent nature of the accumulation in this area can result in the exclusion of entire seasons from the isotope records. The temperature records also reveal that the oxygen isotope records in these snow pits are biased towards higher temperatures, since snowfall conditions are associated with higher temperatures. This effect is greatest at low temperatures. A comparison between the seasonal extreme isotopic and temperature values points out that on timescales of seasons to several years, isotopic variability cannot be interpreted with confidence as temperature changes at the accumulation sites

  16. ReWritable Data Storage on DVD by Using Phase Change Technology

    Kleine, H.; Martin, F.; Kapeller, M.; Cord, B.; Ebinger, H.

    It is expected that the next few years the VHS casette will be replaced by rewritable Digital Versatile Discs (DVD) for home video recording. At this moment three different standards DVD+RW, DVD-RW and DVD-RAM exist, out of which the DVD+RW is expected to dominate the market in Europe and the United States. The disc holds 4.7 GB of computer data, which is equivalent to several hours of high quality video content. At the heart of the disc is a thin film layer stack with a special phase change recording layer. By proper laser irradiation the disc can be overwritten up to 1000 times without noticeable quality loss. A shelf lifetime of 20-50 years is anticipated. With these characteristics the disc is well suited for consumer applications. The present article illuminates how a process engineer can control the disc recording sensitivity, the recording speed and the number of overwriting cycles by the design of the thin film layer stack.

    To examine the Manufacturer and User Facility Device Experience Database (MAUDE) database to capture adverse events experienced with the Da Vinci Surgical System. In addition, to design a standardized classification system to categorize the complications and machine failures associated with the device. Overall, 1,057,000 DaVinci procedures were performed in the United States between 2009 and 2012. Currently, no system exists for classifying and comparing device-related errors and complications with which to evaluate adverse events associated with the Da Vinci Surgical System. The MAUDE database was queried for events reports related to the DaVinci Surgical System between the years 2009 and 2012. A classification system was developed and tested among 14 robotic surgeons to associate a level of severity with each event and its relationship to the DaVinci Surgical System. Events were then classified according to this system and examined by using Chi-square analysis. Two thousand eight hundred thirty-seven events were identified, of which 34% were obstetrics and gynecology (Ob/Gyn); 19%, urology; 11%, other; and 36%, not specified. Our classification system had moderate agreement with a Kappa score of 0.52. Using our classification system, we identified 75% of the events as mild, 18% as moderate, 4% as severe, and 3% as life threatening or resulting in death. Seventy-seven percent were classified as definitely related to the device, 15% as possibly related, and 8% as not related. Urology procedures compared with Ob/Gyn were associated with more severe events (38% vs 26%, p tool with moderate inter-rater agreement that can be used to better understand device-related adverse events. The majority of robotic related events were mild but associated with the device.

    Full Text Available The character of Charlot, created by Charles Chaplin, rewrites the myth of don Quixote in silent movies. While sharing the roots of the picaresque tradition, they represent a harsh criticism of modernity in all its stages. A distinction has to be made between the plain vaudevillesque humor of Charlot in the brief comic strips from 1914 and its tragi-comical shaping in some short films from 1915 up to Modern Times (1936. Beyond their mere physical aspects and their hilarious exploits, an underlying tragic heroism and idealism lead them to uphold all good causes and to support the wronged ones while they also struggle for survival. Charlot combines the comic with the sublime and, as well as the ingenious hidalgo, his soul becomes gradually fuller, deeper and more human. For all these reasons, this character could be regarded as a “quixote” of the big screen.

    - In the early 1900s, it was common practice to retain, prepare, and display instructive pathologic specimens to teach pathology to medical trainees and practitioners; these collections were called medical museums. Maude Abbott established her reputation by developing expertise in all aspects of medical museum work. She was a founder of the International Association of Medical Museums (later renamed the International Academy of Pathology) and became an internationally renowned expert on congenital heart disease. Her involvement in the Canadian Medical War Museum (CMWM) is less well known. - To explore Abbott's role in the development of the CMWM during and after World War I and to trace its history. - Available primary and secondary historical sources were reviewed. - Instructive pathologic specimens derived from Canadian soldiers dying during World War I were shipped to the Royal College of Surgeons in London, which served as a clearinghouse for museum specimens from Dominion forces. The Canadian specimens were repatriated to Canada, prepared by Abbott, and displayed at several medical meetings. Abbott, because she was a woman, could not enlist and so she reported to a series of enlisted physicians with no expertise in museology. Plans for a permanent CMWM building in Ottawa eventually failed and Abbott maintained the collection at McGill (Montreal, Quebec, Canada) until her death in 1940. We trace the CMWM after her death. - Sadly, after Abbott had meticulously prepared these precious teaching specimens so that their previous owners' ultimate sacrifice would continue to help their military brethren, the relics were bureaucratically lost.

    Organic molecules having extended π-conjugated moieties is useful for creating 'dynamic' functional materials by modulating the photophysical properties and molecular packing through non-covalent interactions. Herein, we report the photoluminescence properties of a luminogen, NBA, exhibiting aggregation-induced emission (AIE) characteristics, synthesized by Knoevenagel condensation reaction between 2-Hydroxy naphthaldehyde and malononitrile. NBA emits strongly upon aggregation and in solid state with large Stokes shift whereas it is non emissive in pure solvents. The aggregation induced emission behavior of the compound was carried out in DMSO (good solvent)-water mixture (poor solvent) with water fraction (fw) ranging from 0% to 98%. The AIE property of the luminogen were further exploited for fabricating rewritable fluorescent paper substrates that found applications in security printing and data storage where the written images or letters stored on the filter paper are invisible under normal light.

    Full Text Available Living organisms have evolved over millions of years to fine tune their metabolism to create efficient pathways for producing metabolites necessary for their survival. Advancement in the field of synthetic biology has enabled the exploitation of these metabolic pathways for the production of desired compounds by creating microbial cell factories through metabolic engineering, thus providing sustainable routes to obtain value-added chemicals. Following the past success in metabolic engineering, there is increasing interest in diversifying natural metabolic pathways to construct non-natural biosynthesis routes, thereby creating possibilities for producing novel valuable compounds that are non-natural or without elucidated biosynthesis pathways. Thus, the range of chemicals that can be produced by biological systems can be expanded to meet the demands of industries for compounds such as plastic precursors and new antibiotics, most of which can only be obtained through chemical synthesis currently. Herein, we review and discuss novel strategies that have been developed to rewrite natural metabolic blueprints in a bid to broaden the chemical repertoire achievable in microorganisms. This review aims to provide insights on recent approaches taken to open new avenues for achieving biochemical production that are beyond currently available inventions.

    2013-09-01

    Understanding how important phenotypic, developmental, and genomic features of animals originated and evolved is essential for many fields of biological research, but such understanding depends on robust hypotheses about the phylogenetic interrelationships of the higher taxa to which the studied species belong. Molecular approaches to phylogenetics have proven able to revolutionize our knowledge of organismal evolution. However, with respect to the deepest splits in the metazoan Tree of Life-the relationships between Bilateria and the four non-bilaterian phyla (Porifera, Placozoa, Ctenophora, and Cnidaria)-no consensus has been reached yet, since a number of different, often contradictory, hypotheses with sometimes spectacular implications have been proposed in recent years. Here, we review the recent literature on the topic and contrast it with more classical perceptions based on analyses of morphological characters. We conclude that the time is not yet ripe to rewrite zoological textbooks and advocate a conservative approach when it comes to developing scenarios of the early evolution of animals.

    Full Text Available Photography was a key medium for creating, spreading, and cementing myths about the Cuban Revolution and its leaders. In the first part of this essay, I’ll explore several iconic images as well as responses to these pictures, all parts of a Cuban “cross-national memory discourse” (cf. Quiroga, 2005. Walter Benjamin’s media philosophy can help in developing insights about the functioning of these photographs. In the second part of the paper, I turn to Tania Bruguera’s piece Tatlin’s Whisper#6 (staged at the 10th Havana Biennial in 2009, which radically rewrites the poetics of the images and aspires to create a sense of participation and direct involvement.

    Full Text Available Since the ancient times, the fairy tale manages to catch the imagination of human beings everywhere in the world. Its appeal comes to us even thanks to reinterpretations, constant contaminations from different media, from the oral writing, from cinema to theatre, from advertising to animation. This article will highlight the key features of a very much analysed genre, after the most recent studies and will follow it also by referring to the new routes that it has embarked on in our time. Special attention is then paid on the woman presence and on her origin and evolution that she, in her most varied personifications – innocent girl persecuted by the fairy and by the witch – has suffered up to the latest rewriting of the fairy tales.

    Reversible multicolor displays on solid media using single molecule pigments have been a long-awaited goal. Herein, a new and simple molecular dyad, which can undergo switchable CMY color changes both in solution and solid substrate upon exposure to light, water/acid, and nucleophiles, is designed and synthesized. The stimuli used in this work can be applied independent of each other, which is beneficial for color changes without mutual interference. As a comparison, the mixtures of the two molecular switching motifs forming the basis of the dyad were also studied. The dyad greatly outperforms the corresponding mixed system with respect to reversible color-switching on the paper substrate. Its potential for full-color rewritable paper with excellent reversibility has been demonstrated. Legible multicolor prints, that is, high color contrast and resolution, good dispersion, excellent reversibility, were achieved using common water-jet and light-based printers. This work provides a very promising approach for further development of full-color switchable molecules, materials and displays. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  8. Relativistic particles coupled to Chern-Simons term-revisited

    International Nuclear Information System (INIS)

    Chakraborty, B.

    1995-01-01

    The author considers the model of N relativistic spinless particles coupled to an abelian Chern-Simons term. Rewriting the action in a time reparamaterized form by introducing an arbitary parameter, parameterizing the world line of the particles, the author makes a classical constraint Hamiltonian analysis of the model. Subsequent to gauge fixing by equating the arbitrary parameter with the time the author identifies the Hamiltonian of the system, which agrees with the Hamiltonian obtained by using Banerjee's method of fixing the arbitrary Langrange multiplier by using equations of motion. The author exhibits the Poincare invariance of the model, at the classical level, by constructing spacetime generators using either the canonical or symmetric definition of the energy-momentum tensor. A detailed comparison of the expressions of angular momentum obtained by both methods show that both agree up to a boundary term. In presence of rotationally symmetric vortex configuration this term can be interpreted as an anomalous angular momentum term. The author also heuristically discusses the effect of gauge fixing on the transformation properties. 13 refs

    In this system description, we present the tool AProVE for automatic termination and complexity proofs of Java, C, Haskell, Prolog, and rewrite systems. In addition to classical term rewrite systems (TRSs), AProVE also supports rewrite systems containing built-in integers (int-TRSs). To analyze...... programs in high-level languages, AProVE automatically converts them to (int-)TRSs. Then, a wide range of techniques is employed to prove termination and to infer complexity bounds for the resulting rewrite systems. The generated proofs can be exported to check their correctness using automatic certifiers...

  10. Anachronism and the rewriting of history: the South Africa case

    Directory of Open Access Journals (Sweden)

    Georgi Verbeeck

    2006-04-01

    Full Text Available The use and abuse of anachronism is often seen as the quintessence of the writing of history. Historians tend to conceive it as the hardcore of their métier to avoid anachronism. It designates a confusion in order of time, especially the mistake of placing an event, attitude, or circumstance too early. The awareness of historical anachronism is omnipresent in times of a radical rewriting of history, in particular as a result of political transformation. History reflects the needs and ambitions of a political context, and the sense of what is deemed historically significant does not remain unattached hereby. Chronology and anachronism are essential to particular conceptions of history, and if history is in a process of being rewritten, they are the first items to be addressed by the defenders of the old system and the advocates of a new discourse. In political debates on the use or abuse of history anachronism is often seen as ultimate proof of the (un-reliability of new insights and conceptions. As anachronism is defined as a way of transferring contemporary sets of values, assumptions and interpretative categories, every political reorientation inevitably provokes a discussion on that level. If a ‘new nation’ is in search of a ‘new past’, a new reflection on the basic categories of historical thinking becomes necessary. The changing discourses in South African historiography since the end of Apartheid serve here as an illuminative example.

    2009-04-01

    This paper presents a single-phase written pole motor using a bonded ring magnet for the small power home application. The motor has an exciter pole structure inside the stator and hybrid characteristics of an induction motor and permanent magnet motor. The design parameters and operating characteristics of the hybrid concept motor are investigated to increase starting torque and efficiency, which is most important for the small power home application. Larger starting torque and higher efficiency than those of the conventional induction motor could be obtained by using the rewritable characteristics of bonded magnet on the starting and running conditions.

    2015-08-01

    Full Text Available Drawing on in-depth interviews with sixteen Facebook users, this paper presents a series of vignettes that explore cross-platform Facebook apps as ‘tools’ for self-writing, self-expression and identity performance. The paper argues that the capacity of apps to write in the user’s stead – at times without the user’s knowledge or explicit consent – works to intervene in and on occasion disrupt users’ staged self-performances to their ‘invisible audience’ (Sauter, 2013 on Facebook. Furthermore, if such instances of automated self-writing are treated as performative, apps hold the constitutional capacity to actively rewrite, regulate and even constitute the self to suit the logic of the ‘like economy’ (Gelitz and Helmond, 2013, in ways that transcend the boundaries of Facebook.

  15. Re-thinking representations, re-writing nursing texts: possibilities through feminist and Foucauldian thought.

    Science.gov (United States)

    Huntington, A D; Gilmour, J A

    2001-09-01

    Critical approaches are increasingly being used to inform theory and research within the discipline of nursing. In this paper we discuss the work of feminist writers, particularly those located within the postmodern, and Michel Foucault. Their work, although having significant points of difference, can be viewed as complementary and our engagement with these ideas has led us to re-think nursing knowledge. Using ideas from Foucault and postmodern feminism foregrounds critical questions such as whose knowledge is visible in nursing literature, whose is suppressed, and the power relationships reflected in representations of knowledge. Our exploration of representations of knowledge has led us to review fundamental nursing texts that we consider to be important political and ideological artefacts in the enculturation of student nurses. The dominant position of medical knowledge in the texts reviewed continues to position this 'voice' as primary in nursing literature. Drawing on our current research on endometriosis to illustrate the potential inherent in rewriting such texts, we argue for a repositioning of knowledge related to the illness experience. Privileging the voices of people who are the focus of our clinical care reflects the reality of nurses' work; the embodied experience of the person is made visible rather than marginalized in the illness discourse.

  16. Evidence for the former existence of a thicker ice sheet on the Vestfjella nunataks in western Dronning Maud Land, Antarctica

    Directory of Open Access Journals (Sweden)

    Lintinen, P.

    1996-06-01

    Full Text Available Vestfjella (73-74°S, 13-16°W is a 130 km long nunatak range in western Dronning Maud Land in East Antarctica, and its northern and southern ends are situated close to the present ice sheet grounding-line. Striations and lodgement till on nunatak Basen indicate that the northernmost Vestfjella nunataks were formerly covered by a thicker Antarctic ice sheet. Striations on the summit ridge of nunatak Plogen indicate that the minimum change in ice thickness has been 700 m at the present ice sheet grounding-line. The relatively uniform oldest striation direction on different nunatak summits and the altitude of Plogen, which is less than 200 m lower than the highest Vestfjella summits, indicates that the whole of Vestfjella may have been covered by an ice sheet. Oxidation of till surface stones and an increased clay fraction in the upper part of the till layer were the only indications of soil formation on Basen. The unweathered nature of the Basen lodgement till indicate a relatively young age for deglaciation. This conclusion is also supported by age determinations and sedimentological data obtained from Weddell Sea sediments by Norwegian researchers, suggesting that a grounded ice sheet extended to the shelf edge at around 21 ka B.P. However the age of the glaciation which covered Basen and Plogen and the subsequent deglaciation is not based on precise dates and therefore the late Wisconsinan/Weichselian age is only a working hypothesis.

    More than a personal microblogging site, Twitter has been transformed by common use to an information publishing venue, which public characters, media channels and common people daily rely on for, e.g., news reporting and consumption, marketing, and social messaging. The use of Twitter...... in a cooperative and interactive setting calls for the precise awareness of the dynamics regulating message spreading. In this paper, we describe Twitlang, a language for modelling the interactions among Twitter accounts.

    Development of rewritable DVD is desired which has feedback compatibility with the existing players and ROM drives. The DVD is formed on a substrate with a thickness of 0.6 mm (dummy plate), and is composed of the multilayer film, i.e., protective coating made of UV hardening resin, reflective layer, dielectric protective layer, phase change type recording layer, and polycarbonate layer from the lower in order. A pair of dummy plates are pasted to enhance the mechanical strength, which has the same thickness of 1.2 mm as CD. Since the grooves and prepits are very fine, injection molding is more difficult compared with CD. Since a great stress change occurs during the formation and initialization processes of multilayer of phase change recording medium layer which is particular to DVD manufacturing process, control of warping is significant. Control of warping of the substrate is also significant, which affects the pasting and the whole process. The recording layer, dielectric protective layer and reflective layer are formed by the discharge spattering. The initialization is a particular process to the phase change medium. Complete non-recording state can be obtained by crystallizing the amorphous recording layer after the film formation. 3 figs.

  19. Petrogenesis of peralkaline granite dykes of the Straumsvola complex, western Dronning Maud Land, Antarctica

    Harris, Chris; Dreyer, Tanya; le Roux, Petrus

    2018-01-01

    Peralkaline syenite and granite dykes cut the Straumsvola nepheline syenite pluton in Western Dronning Maud Land, Antarctica. The average peralkalinity index (PI = molecular Al/[Na + K]) of the dykes is 1.20 ( n = 29) and manifests itself in the presence of the Zr silicates eudialyte, dalyite and vlasovite, and the Na-Ti silicate, narsarsukite. The dykes appear to have intruded during slow cooling of the nepheline syenite pluton, and the petrogenetic relationship of the dykes and the pluton cannot be related to closed-system processes at low pressure, given the thermal divide that exists between silica-undersaturated and oversaturated magmas. Major and trace element variations in the dykes are consistent with a combination of fractional crystallization of parental peralkaline magma of quartz trachyte composition, and internal mineral segregation prior to final solidification. The distribution of accessory minerals is consistent with late-stage crystallization of isolated melt pockets. The dykes give an Rb-Sr isochron age of 171 ± 4.4 Ma, with variable initial 87Sr/86Sr ratio (0.7075 ± 0.0032), and have an average ɛ Nd of - 12.0. Quartz phenocrysts have δ18O values of 8.4-9.2‰, which are generally in O-isotope equilibrium with bulk rock. Differences in the δ18O values of quartz and aegirine (average Δquartz-aegirine = 3.5‰) suggest aegirine formation temperatures around 500 °C, lower than expected for a felsic magma, but consistent with poikilitic aegirine that indicates subsolidus growth. The negative ɛ Nd (< - 10) and magma δ18O values averaging 8.6‰ (assuming Δquartz-magma = 0.6‰) are inconsistent with a magma produced by closed-system fractional crystallization of a mantle-derived magma. By contrast, the nepheline syenite magma had mantle-like δ18O values and much less negative ɛ Nd (average - 3.1, n = 3). The country rock has similar δ18O values to the granite dykes (average 8.0‰, n = 108); this means that models for the petrogenesis of

    Directory of Open Access Journals (Sweden)

    Vuorio, Pia

    2016-12-01

    Full Text Available One of the most complex forms of relationship in fiction for young adults seems to be the one between mothers and daughters. The Swedish author Maud Reuterswärd (1920−1980 has written several books for young adults in which a relational crisis between a mother and her daughter is the central theme. Throughout Reuterswärd’s trilogy about Elisabet Hof, the mother plays a key role. The trilogy features an emotionally instable and mentally absent mother whose depression eventually leads to her attempting to commit suicide. Through a psychoanalytical lens, this paper highlights and discusses how the mother-daughter relationship in Reuterswärd’s trilogy is mediated through dialogue, point of view and tone. The mother’s voice and the verbal communication between mother and daughter is focused by using Luce Irigaray’s theoretical approach of the maternal function in psychoanalysis and culture. In addition the paper attempts to widen the critical perspectives and provide alternative ways of understanding the mother in Reuterswärd’s trilogy.

    The most direct method of investigating past variations of the atmospheric CO 2 concentration before 1958, when continuous direct atmospheric CO 2 measurements started, is the analysis of air extracted from suitable ice cores. Here we present a new detailed CO 2 record from the Dronning Maud Land (DML) ice core, drilled in the framework of the European Project for Ice Coring in Antarctica (EPICA) and some new measurements on a previously drilled ice core from the South Pole. The DML CO 2 record shows an increase from about 278 to 282 parts per million by volume (ppmv) between ad 1000 and ad 1200 and a fairly continuous decrease to a mean value of about 277 ppmv around ad 1700. While the new South Pole measurements agree well with DML at the minimum at ad 1700 they are on average about 2 ppmv lower during the period ad 1000-1500. Published measurements from the coastal high-accumulation site Law Dome are considered as very reliable because of the reproducibility of the measurements, high temporal resolution and an accurate time scale. Other Antarctic ice cores could not, or only partly, reproduce the pre-industrial measurements from Law Dome. A comparison of the trends of DML and Law Dome shows a general agreement. However we should be able to rule out co-variations caused by the same artefact. Two possible effects are discussed, first production of CO 2 by chemical reactions and second diffusion of dissolved air through the ice matrix into the bubbles. While the first effect cannot be totally excluded, comparison of the Law Dome and DML record shows that dissolved air diffusing to bubbles cannot be responsible for the pre-industrial variation. Therefore, the new record is not a proof of the Law Dome results but the first very strong support from an ice core of the Antarctic plateau

    Directory of Open Access Journals (Sweden)

    Frances Jane P. Abao

    2000-12-01

    Full Text Available Despite its ongoing popularity with women readers, romantic fiction has traditionally been regarded as an instrument of women's oppression, largely due to its reinforcement and even glorification of sexual stereotypes and bourgeois values. Latin American writer Isabel Allende's novels The House of the Spirits and Eva Luna both contain a number of the elements and conventions of romantic fiction, including distinct similarities to the two acknowledged foundations of this genre: Charlotte Brontë's Jane Eyre and Emily Brontë's Wuthering Heights.However, The House of the Spirits and Eva Luna can also be read as rewritings of the genre of romantic fiction. In these two texts, Isabel Allende appropriates and then reworks certain conventions of romantic fiction in order to portray her notion of "fulfilling egalitarian relationships" between men and women. Nevertheless, despite these feminist revisions, Allende's rewritten romances do retain the "wish-fulfillment" element-or ideal-of romantic fiction, its depiction of women's fantasy of feminine values being appreciated and validated within heterosexual romantic relationships in the real world.

    Graphitic carbon nitride nanosheet (g-C3N4-NS) has layered structure similar with graphene nanosheet and presents unusual physicochemical properties due to the s-triazine fragments. But their electronic and electrochemical applications are limited by the relatively poor conductivity. The current work provides the first example that atomically thick g-C3N4-NSs are the ideal candidate as the active insulator layer with tunable conductivity for achieving the high performance memory devices with electrical bistability. Unlike in conventional memory diodes, the g-C3N4-NSs based devices combined with graphene layer electrodes are flexible, metal-free and low cost. The functionalized g-C3N4-NSs exhibit desirable dispersibility and dielectricity which support the all-solution fabrication and high performance of the memory diodes. Moreover, the flexible memory diodes are conveniently fabricated through the fast laser writing process on graphene oxide/g-C3N4-NSs/graphene oxide thin film. The obtained devices not only have the nonvolatile electrical bistability with great retention and endurance, but also show the rewritable memory effect with a reliable ON/OFF ratio of up to 105, which is the highest among all the metal-free flexible memory diodes reported so far, and even higher than those of metal-containing devices.

A partir de unas primeras experimentaciones con reescritura de textos literarios, se puede concluir que las nociones de tono y estilo están intuitivamente disponibles para los escritores noveles y son por tanto excelentes candidatas para ser operativas en la formación en traducción literaria.  The distinguishing characteristics of First Language training - a vaguely defined area of study which is not usually explored in literary publications - will form the basis of our investigation.  We will consider two sets of activities, both linked to evaluation and rewriting, which will allow us to explore the concepts of intentional reading and deautomisation of the writing process. These notions seem especially useful for encouraging creativity in language use, a highly important skill in literary translation. Based on the results of a few initial experiments involving the rewriting of literary texts, we can conclude that novice writers are intuitively aware of tone and style. These notions could therefore provide an excellent focus for literary translation training.

    Major ions were analysed in firn and ice cores located at Fimbul Ice Shelf (FIS), Dronning Maud Land - DML, Antarctica. FIS is the largest ice shelf in the Haakon VII Sea, with an extent of approximately 36 500 km2. Three shallow firn cores (about 20 m deep) were retrieved in different ice rises, Kupol Ciolkovskogo (KC), Kupol Moskovskij (KM), and Blåskimen Island (BI), while a 100 m long core (S100) was drilled near the FIS edge. These sites are distributed over the entire FIS area so that they provide a variety of elevation (50-400 m a.s.l.) and distance (3-42 km) to the sea. Sea-salt species (mainly Na+ and Cl-) generally dominate the precipitation chemistry in the study region. We associate a significant sixfold increase in median sea-salt concentrations, observed in the S100 core after the 1950s, to an enhanced exposure of the S100 site to primary sea-salt aerosol due to a shorter distance from the S100 site to the ice front, and to enhanced sea-salt aerosol production from blowing salty snow over sea ice, most likely related to the calving of Trolltunga occurred during the 1960s. This increase in sea-salt concentrations is synchronous with a shift in non-sea-salt sulfate (nssSO42-) toward negative values, suggesting a possible contribution of fractionated aerosol to the sea-salt load in the S100 core most likely originating from salty snow found on sea ice. In contrast, there is no evidence of a significant contribution of fractionated sea salt to the ice-rises sites, where the signal would be most likely masked by the large inputs of biogenic sulfate estimated for these sites. In summary, these results suggest that the S100 core contains a sea-salt record dominated by the proximity of the site to the ocean, and processes of sea ice formation in the neighbouring waters. In contrast, the ice-rises firn cores register a larger-scale signal of atmospheric flow conditions and a less efficient transport of sea-salt aerosols to these sites. These findings are a

  12. The Afterlife of Thomas Campbell and ‘The Soldier’s Dream’ in the Crimean War

    Full Text Available Studies of Crimean War poetry tend to focus on Alfred Tennyson’s celebrated war poem ‘The Charge of the Light Brigade’ (1854, a civilian poetic rewriting of 'The Times'’s despatches. While recent scholarship has highlighted the impact of modern forms of reportage on artistic representations of the Crimean War, this article will argue that the two-year military campaign waged at a long distance was not only a media war but also a literary one, during which civilians drew on established forms of war poetry to make sense of the pressing issues provoked by the conflict overseas. This literary war was manifest in the myriad ways armchair poets and artists rewrote Thomas Campbell’s ‘The Soldier’s Dream’ (1804 to address the reading public’s anxieties and expectations about the welfare of the common soldier. The rewritings of Campbell’s poem this article will consider include: 'Punch'’s ‘The Soldier’s Dream’ alongside an accompanying cartoon by John Tenniel of 1 April 1854; the poem ‘A Night on the Heights’, penned by the pseudonymous poet ‘Private Jones’ in 'Tait’s Edinburgh Magazine' in December 1854; a piece of commemorative pottery designed by George Eyre in January 1855; and Part III of Tennyson’s ‘Maud’, published in 'Maud and Other Poems' in July 1855. By examining these works at specific moments of the conflict, I will demonstrate that mid-Victorians deployed Campbell’s dream-vision framework to negotiate the soldier’s public duties and private emotions, as well as the government’s responsibilities for the soldier and his family. While in general mid-century commentators utilized Campbell’s dream vision to foreground a benign government’s efforts to care for the soldier, Tennyson’s conclusion of ‘Maud’' 'offered an ironic rendition of this interpretation. Instead, a civilian’s dream of fighting a glorious war becomes a nightmarish vision of the government’s military incompetence

    Graphitic carbon nitride nanosheet (g-C3N4-NS) has layered structure similar with graphene nanosheet and presents unusual physicochemical properties due to the s-triazine fragments. But their electronic and electrochemical applications are limited by the relatively poor conductivity. The current work provides the first example that atomically thick g-C3N4-NSs are the ideal candidate as the active insulator layer with tunable conductivity for achieving the high performance memory devices with electrical bistability. Unlike in conventional memory diodes, the g-C3N4-NSs based devices combined with graphene layer electrodes are flexible, metal-free and low cost. The functionalized g-C3N4-NSs exhibit desirable dispersibility and dielectricity which support the all-solution fabrication and high performance of the memory diodes. Moreover, the flexible memory diodes are conveniently fabricated through the fast laser writing process on graphene oxide/g-C3N4-NSs/graphene oxide thin film. The obtained devices not only have the nonvolatile electrical bistability with great retention and endurance, but also show the rewritable memory effect with a reliable ON/OFF ratio of up to 105, which is the highest among all the metal-free flexible memory diodes reported so far, and even higher than those of metal-containing devices.

  15. Rewriting the Matrix of Life. Biomedia Between Ecological Crisis and Playful Actions

    Directory of Open Access Journals (Sweden)

    Christoph Neubert, Serjoscha Wiemer

    2014-09-01

    Full Text Available The paper discusses concepts of ‘nature’ and ‘life’ as subjected to historical changes. The 21st century seems to be obsessed with ‘life’ and ‘nature’, which are reconfigured as objects of simulation practices and of a multitude of technoscientific enterprises as well as of political struggle. The historical influences and epistemological shifts of systems thinking are significant within two distinctive and interwoven fields: On the one hand the discourse of environmentalism with the paradigm of ecological crises, centered around ideas of resource management, sustainability, the general idea of an ‘endangered nature’ and the interconnectedness of global politics and individual actions. On the other hand the optimistic promises of artificial life, with synthetic biology and digital cyborg technologies as its avantgarde, which are very much driven by the idea of technoscientific mastery to surpass natures ‘weakness’ and by desires to improve ‘life’ and to even refashion ‘life itself’. On the field of historical ecology, concepts of systems thinking are traced back to the middle of the 19th century, where ecological thought emerged at the intersections of biology and geography. Meandering between vitalistic, holistic, and mechanistic concepts, between living and non-living elements, systems ecology finally substitutes ‘nature’, which in turn is re-established in its new ‘gestalt’ as computer simulated world model since the early 1970s. Resurrected as an interrelation of system variables at the level of global simulations ‘nature’ strikes as a zombie. As a second turning point of the rewriting of the matrix, of life we will discuss the advance of ‘games’ since the early 1970ies, with the example of ‘Game of life’ (‘Life’ as a significant landmark. When ‘life’ becomes ‘Life’, it is by computerized modeling in terms of dynamic processes. Computer games can be thought of as instances of

    Full Text Available Lin Haire-Sargeant’s 1992 novel The Story of Heathcliff’s Journey Back to Wuthering Heights is typical of the interest shown by contemporary American writers in Victorian novels. It could indeed be classified doubly as a “retro-Victorian novel” since it partly re-writes not only Emily Brontë’s most famous novel, Wuthering Heights, as the title points out, but also, somewhat less obviously, Charlotte Brontë’s Jane Eyre. We will study in this article how Lin Haire-Sargeant’s attempt at re-writing highlights the usual aims of the retro-Victorian novel: taking advantage of the blanks left by the source novels to propose to the reader a modern critical approach, while at the same time being as faithful as possible to the writing conventions of the 19th century, and suggesting another point of view on a well-known story, through a postmodern mixing of historical and fictive characters.

  17. New aeromagnetic data of eastern Dronning Maud Land: implications for the spatial extent of a major Early Neoproterozoic juvenile crustal province

    A long-standing collaboration between Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) and the Federal Institute for Geosciences and Natural Resources (BGR) aims to investigate the sub-ice crustal architecture and tectonic evolution of East Antarctica. Its main emphasis is on Dronning Maud Land (DML). During the austral summers 2014 and 2015, ca. 40.000 line kilometre of new magnetic, gravity and ice-penetrating radar data were collected with 10 km line spacing. Here, we report on magnetic anomaly data to the east and south of Sør Rondane (eastern DML), analysed with several filtering techniques. These data are integrated with exposure information from Sør Rondane, the Belgica Mts., and the Yamato Mts.. The study area covers the eastern part of a major, recently revealed Early Neoproterozoic juvenile crustal block, the Tonian Oceanic Arc Super Terrane (TOAST). The western extent of the TOAST is well defined by the Forster Magnetic Anomaly and characterized by a province of subdued SE-striking parallel positive magnetic anomalies in the mostly ice-covered region of south-eastern DML (the SE DML province). Geological investigations showed that this area can be correlated with exposures in Sør Rondane and scattered nunataks west of it. U-Pb ages of ca. 1000-900 Ma, are documented from zircons of gabbro-trondhjemite-tonalite-granodiorite (GTTG) suites in both areas. Further, geochemical analyses prove a juvenile character of the GTTGs, which are interpreted as oceanic arc complexes. Glacial drift from southern Sør Rondane points to an inland continuation of the TOAST, so far of unknown dimensions. The new magnetic data constrain the southern and eastern minimum extent of the TOAST, which we think has a minimum area of 450.000 km2. The spatial extent of this major juvenile crustal province has major significance for the tectonic reconstruction of East Antarctica and its involvement in Rodinia since it is suggested having evolved

    1993-04-01

    We construct a model of the RNA world in terms of naturally evolving nucleotide sequences assuming only Crick-Watson base pairing and self-cleaving/splicing capability. These sequences have the following properties. (1) They are recognizable by an automation (or automata). That is, to each k-sequence, there exist a k-automation which accepts, recognizes or generates the k-sequence. These are known as automatic sequences. Fibonacci and Morse-Thue sequences are the most natural outcome of pre-biotic chemical conditions. (2) Infinite (resp. large) sequences are self-similar (resp. nearly self-similar) under certain rewrite rules and consequently give rise to fractal (resp.fractal-like) structures. Computationally, such sequences can also be generated by their corresponding deterministic parallel re-write system, known as a DOL system. The self-similar sequences are fixed points of their respective rewrite rules. Some of these automatic sequences have the capability that they can read or ``accept`` other sequences while others can detect errors and trigger error-correcting mechanisms. They can be enlarged and have block and/or palindrome structure. Linear recurring sequences such as Fibonacci sequence are simply Feed-back Shift Registers, a well know model of information processing machines. We show that a mutation of any rewrite rule can cause a combinatorial explosion of error and relates this to oncogenetical behavior. On the other hand, a mutation of sequences that are not rewrite rules, leads to normal evolutionary change. Known experimental results support our hypothesis. (author). Refs.

  20. Finite automata, their algebras and grammars towards a theory of formal expressions

    Büchi, J Richard

    1989-01-01

    The author, who died in 1984, is well-known both as a person and through his research in mathematical logic and theoretical computer science. In the first part of the book he presents the new classical theory of finite automata as unary algebras which he himself invented about 30 years ago. Many results, like his work on structure lattices or his characterization of regular sets by generalized regular rules, are unknown to a wider audience. In the second part of the book he extends the theory to general (non-unary, many-sorted) algebras, term rewriting systems, tree automata, and pushdown automata. Essentially Büchi worked independent of other rersearch, following a novel and stimulating approach. He aimed for a mathematical theory of terms, but could not finish the book. Many of the results are known by now, but to work further along this line presents a challenging research program on the borderline between universal algebra, term rewriting systems, and automata theory.

    The primary objective of this thesis is to explore the approach of using rule-based systems and strategies, for a complex problem of chemical kinetic: the automated generation of reaction mechanisms. The chemical reactions are naturally expressed as conditional rewriting rules. The control of the chemical reactions chaining is easy to describe using a strategies language, such as the one of the ELAN system, developed in the Protheo team. The thesis presents the basic concepts of the chemical kinetics, the chemical and computational problems related to the conception and validation of a reaction mechanism, and gives a general structure for the generator of reaction mechanisms called GasEI. Our research focuses on the primary mechanism generator. We give solutions for encoding the chemical species, the reactions and their chaining, and we present the prototype developed in ELAN. The representation of the chemical species uses the notion of molecular graphs, encoded by a term structure called GasEI terms. The chemical reactions are expressed by rewriting rules on molecular graphs, encoded by a set of conditional rewriting rules on GasEI terms. The strategies language of the ELAN system is used to express the reactions chaining in the primary mechanism generator. This approach is illustrated by coding ten generic reactions of the oxidizing pyrolysis. Qualitative chemical validations of the prototype show that our approach gives, for acyclic molecules, the same results as the existing mechanism generators, and for polycyclic molecules produces original results.

    Full Text Available As the anonymous author of “The Hard Church Novel” underlined in his article, “Theology and Literature – the study of God and the study of Man – need to go hand in hand, and are only just beginning to know it”. The links between literature and religion are in fact much older than we might imagine when reading this statement; however, it is a fact that the Victorian period was a time when many authors tried to reconcile secular writing and the Scriptures, to the extent that a new literary genre, the religious novel, was born. Although Elizabeth Gaskell’s works do not belong to this category, she set her heart on reconciling her vocation as a novelist with her beliefs as a Christian. Unlike her husband, she was not a Minister and therefore her own way of preaching the Word of God was to write fiction. She was convinced that the Pharisees had not disappeared with the Advent of Christ and, in her novels, she used her own, sometimes unorthodox, interpretation and rewriting of the Gospels to convert the Pharisees of her own time to the true essence of Christianity. Indeed, her Unitarian education granted her a greater freedom than most of her contemporaries in terms of biblical exegesis, as we can see in many of her works, but most particularly in Ruth, in which the eponymous heroine, a fallen woman, is not only described as a Magdalen but soon turns into a Madonna and then a Christ-like figure.

    2018-03-01

    To assess the utility of the Manufacturer And User Facility Device Experience (MAUDE) database in objectively capturing adverse events for transvaginal mesh in the United States. We reviewed 1,103 individual medical device reports submitted to the MAUDE database that inspired the United States (US) Food and Drug Administration's 2008 Public Health Notification. Entries were compiled into a categorical database that reported manufacturer, brand, reporter type, report source, and type of adverse event. There were numerous examples of missing, duplicated, and non-standardized entries. Analysis revealed 64 reports with duplicated information, and six reports representing multiple patients. Forty-seven percent of medical device reports did not identify a reporter source. At least 28% of reported devices are no longer on the US market. There was wide variability in the quality and completeness of submitted reports and true adverse event rates could not be accurately calculated because the number of total cases was unknown. The MAUDE database was limited in its ability to collect, quantify, and standardize real-life adverse events related to transvaginal mesh. While it functions to collect information related to isolated adverse events, systematic limitations of the MAUDE database, that no doubt extend to other medical devices, necessitate the development of new reporting systems. Alternatives are under development, which may allow regulators to more accurately scrutinize the safety profiles of specific medical devices.

    Optical holographic storage in single-crystal LiNbO3 is described which can be optically erased at room temperature and then rewritten with no degradation in efficiency or writing rate. The diffraction efficiencies associated with the process are about 0.0001. Some variations from previously obtained results include a lack of threshold power density for writing, very-long-term persistence of the stored hologram, and a lack of a dependence of the diffracted intensity on the polarization of the readout beam.

    Occasional very intense snowfall events over Dronning Maud Land (DML) region in East Antarctica, contributed significantly to the entire Antarctic ice sheet surface mass balance (SMB) during the last years. The meteorological-cloud-precipitation observatory running at the Princess Elisabeth station (PE) in the DML escarpment zone since 2009 (HYDRANT/AEROCLOUD projects), provides unique opportunity to estimate contribution of precipitation to the local snow accumulation and new data for evaluating precipitation in climate models. Our previous work using PE measurements showed that occasional intense precipitation events determine the total local yearly SMB and account for its large interannual variability. Here we use radar measurements to evaluate precipitation in a regional climate model with a special focus on intense precipitation events together with the large-scale atmospheric dynamics responsible for these events. The coupled snow-atmosphere regional climate model MAR (Modèle Atmosphérique Régional) is used to simulate climate and SMB in DML at 5-km horizontal resolution during 2012 using initial and boundary conditions from the European Centre for Medium-range Weather Forecasts (ECMWF) Interim re-analysis atmospheric and oceanic fields. Two evaluation approaches are used: observations-to-model and model-to-observations. In the first approach, snowfall rate (S) is derived from the MRR (vertically profiling 24-GHz precipitation radar) effective reflectivity factor (Ze) at 400 m agl using various Ze-S relationships for dry snow. The uncertainty in Ze-S relationships is constrained using snow particle size distribution from Snow Video Imager - Precipitation Imaging Package (SVI/PIP) and information about particle shapes. For the second approach we apply the Passive and Active Microwave radiative TRAnsfer model (PAMTRA), which allows direct comparison of the radar-measured and climate model-based vertical profiles of the radar Ze and Doppler velocity.

    Health information technology (HIT) events, a subtype of patient safety events, pose a major threat and barrier toward a safer healthcare system. It is crucial to gain a better understanding of the nature of the errors and adverse events caused by current HIT systems. The scarcity of HIT event-exclusive databases and event reporting systems indicates the challenge of identifying the HIT events from existing resources. FDA Manufacturer and User Facility Device Experience (MAUDE) database is a potential resource for HIT events. However, the low proportion and the rapid evolvement of HIT-related events present challenges for distinguishing them from other equipment failures and hazards. We proposed a strategy to identify and synchronize HIT events from MAUDE by using a filter based on structured features and classifiers based on unstructured features. The strategy will help us develop and grow an HIT event-exclusive database, keeping pace with updates to MAUDE toward shared learning.

    We introduce techniques for proving uniform termination of graph transformation systems, based on matrix interpretations for string rewriting. We generalize this technique by adapting it to graph rewriting instead of string rewriting and by generalizing to ordered semirings. In this way we obtain a

    2010-11-01

    Full Text Available The goal of this article is to discuss how digital war games such as the Call of Duty series elicit consent for the U.S. military, militarism and the wars waged by the U.S. and its allies abroad. Building bridges between the humanities approach to Game Studies, American Studies, International Relations and Critical Geopolitics, we start from the assumption that digital games are more than “kid’s games”; they are sophisticated vehicles inhabiting and disseminating specific ideologies (Leonard 2004. Accordingly, our goal is to conduct a content analysis (Sisler 2008 of Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2 to show how these games contain images and narratives that (1 resonate with and reinforce a tabloid imaginary of post-9/11 geopolitics (Debrix 2008; (2 glorify military power and elicit consent for the idea that state violence and wars are inevitable; and (3 encourage our myopia by depicting a sanitized vision of war and downplaying the negative consequences of state violence (Stahl 2006. The conclusion invites players to think about ways to criticize the way games like Call of Duty employ and deploy values that (rewrite the militarist mindset that has often pervaded the post-9/11 U.S. national security debate.

    The Heisenberg uncertainty relation is expressed in terms of the Tsallis entropies associated with the conjugate coordinate and momentum probability densities. By rewriting this in terms of a positive joint probability distribution suggested by Cohen and coworkers, a different insight into the statistical dependence of the quantum variables is obtained. A discussion of how this improves the previous results on this subject is given. (orig.)

    2018-03-01

    Full Text Available Purpose: To assess the utility of the Manufacturer And User Facility Device Experience (MAUDE database in objectively capturing adverse events for transvaginal mesh in the United States. Materials and Methods: We reviewed 1,103 individual medical device reports submitted to the MAUDE database that inspired the United States (US Food and Drug Administration's 2008 Public Health Notification. Entries were compiled into a categorical database that reported manufacturer, brand, reporter type, report source, and type of adverse event. Results: There were numerous examples of missing, duplicated, and non-standardized entries. Analysis revealed 64 reports with duplicated information, and six reports representing multiple patients. Forty-seven percent of medical device reports did not identify a reporter source. At least 28% of reported devices are no longer on the US market. There was wide variability in the quality and completeness of submitted reports and true adverse event rates could not be accurately calculated because the number of total cases was unknown. Conclusions: The MAUDE database was limited in its ability to collect, quantify, and standardize real-life adverse events related to transvaginal mesh. While it functions to collect information related to isolated adverse events, systematic limitations of the MAUDE database, that no doubt extend to other medical devices, necessitate the development of new reporting systems. Alternatives are under development, which may allow regulators to more accurately scrutinize the safety profiles of specific medical devices.

  2. Hypertextualités décadentes // Decadent hypertextualities

    Directory of Open Access Journals (Sweden)

    Marie-Françoise Melmoux-Montaubin

    2015-12-01

    Full Text Available This article aims at demonstrating the double hypothesis that hypertextuality both constitutes the essence of the end of the century’s literature and explains the negative term of « decadence » used to describe the literary production of the 1880–1900’s. Reading the two founding texts of the decadence, Huysmans’ A rebours (1884 and Les Déliquescences, poèmes décadents d’Adoré Floupette (1885, one can draw some of the major consequences of these practices of rewriting. They mark the end of a mimetic regime of literature defended by the Classics and the Realists, in which the aim is to represent the world, and substitute a new form of creation based on the texts only. They destroy in the same way the claim of originality praised to the skies by the Romantics. Those rewrites also contribute to the setting of new reading strategies that demand culture and erudition. Literature is affected by the rewritings of which she is constantly the object and which sometimes take the appearance of mystifications more or less melancholic. The use of hypertextuality both threatens and enchants literature.

    Previously, Soeken and Thomsen presented six basic semantics-preserving rules for rewriting reversible logic circuits, defined using the well-known diagrammatic notation of Feynman. While this notation is both useful and intuitive for describing reversible circuits, its shortcomings in generality...... complicates the specification of more sophisticated and abstract rewriting rules. In this paper, we introduce Ricercar, a general textual description language for reversible logic circuits designed explicitly to support rewriting. Taking the not gate and the identity gate as primitives, this language allows...... circuits to be constructed using control gates, sequential composition, and ancillae, through a notion of ancilla scope. We show how the above-mentioned rewriting rules are defined in this language, and extend the rewriting system with five additional rules to introduce and modify ancilla scope...

    Full Text Available We describe a tool to create, edit, visualise and compute with interaction nets - a form of graph rewriting systems. The editor, called GraphPaper, allows users to create and edit graphs and their transformation rules using an intuitive user interface. The editor uses the functionalities of the TULIP system, which gives us access to a wealth of visualisation algorithms. Interaction nets are not only a formalism for the specification of graphs, but also a rewrite-based computation model. We discuss graph rewriting strategies and a language to express them in order to perform strategic interaction net rewriting.

    Faulds, Eileen R; Wyne, Kathleen L; Buschur, Elizabeth O; McDaniel, Jodi; Dungan, Kathleen

    2016-06-01

    Insulin pump malfunctions and failures continue to occur; however, more severe malfunctions such as the "runaway pump" phenomenon are rarely reported. This article describes two cases of pump malfunction in which pump users appear to have received an unsolicited bolus of insulin resulting in severe episodes of hypoglycemia during hospitalization. Both cases of insulin pump malfunction occurred in the inpatient setting at a large academic medical center in the United States. An analysis of the corresponding insulin pump downloads was performed. The Food and Drug Administration's (FDA's) Manufacturer and User Facility Device Experience (MAUDE) database was searched for similar cases involving Medtronic (Northridge, CA) insulin pumps using the terms "pump," "infusion," "insulin AND malfunction AND Medtronic." The two cases described show remarkable similarities, each demonstrating a severe hypoglycemic event preceded by an infusion site change followed by an alarm. In both cases a rapid spraying of insulin was reported. The insulin pump downloads validated much of the patients' and medical staff's descriptions of events. The FDA's MAUDE database search revealed 425 cases meeting our search term criteria. All cases were reviewed. Seven cases were identified involving independent movement of the reservoir piston. The cases detailed are the first to describe an insulin pump malfunction of this nature in the hospital setting involving unsolicited insulin boluses leading to severe hypoglycemia. The cases are particularly compelling in that they were witnessed by medical personnel. Providers and patients should receive instruction education on the recognition and management of insulin pump malfunction.

  11. ‘Text’ and ‘voice’ in recent South African poetry

    Directory of Open Access Journals (Sweden)

    C. Woeber

    1996-04-01

    Full Text Available This article explores in some depth two volumes of poetry which are indicative of a tension between the poem as ‘text’ and the poem as ‘voice’, or the self-conscious (metaphoric ‘reading' or ‘rewriting ’ of the world versus the outward (prophetic ‘speaking' to the world. While neither book is hermetically sealed and, like all rich poetry, delights in transgressing categories, each is distinctive enough to lend itself to exploration in terms of ‘text’ and ‘voice’. The article argues that John Mateer, the self-avowed iconoclast yet to find an individual voice, is postmodern in his reading and rewriting of the fragmented world, while Joan Metelerkamp is closer to the modernists in her speaking to the hallowed world as poet-prophet, eschewing textual pyrotechnics while situating herself within poetic tradition.

  13. MatchingTools: A Python library for symbolic effective field theory calculations

    Science.gov (United States)

    Criado, Juan C.

    2018-06-01

    MatchingTools is a Python library for doing symbolic calculations in effective field theory. It provides the tools to construct general models by defining their field content and their interaction Lagrangian. Once a model is given, the heavy particles can be integrated out at the tree level to obtain an effective Lagrangian in which only the light particles appear. After integration, some of the terms of the resulting Lagrangian might not be independent. MatchingTools contains functions for transforming these terms to rewrite them in terms of any chosen set of operators.

  14. Resistive switching effect in the planar structure of all-printed, flexible and rewritable memory device based on advanced 2D nanocomposite of graphene quantum dots and white graphene flakes

    2017-01-01

    Pursuit of the most appropriate materials and fabrication methods is essential for developing a reliable, rewritable and flexible memory device. In this study, we have proposed an advanced 2D nanocomposite of white graphene (hBN) flakes embedded with graphene quantum dots (GQDs) as the functional layer of a flexible memory device owing to their unique electrical, chemical and mechanical properties. Unlike the typical sandwich type structure of a memory device, we developed a cost effective planar structure, to simplify device fabrication and prevent sneak current. The entire device fabrication was carried out using printing technology followed by encapsulation in an atomically thin layer of aluminum oxide (Al 2 O 3 ) for protection against environmental humidity. The proposed memory device exhibited attractive bipolar switching characteristics of high switching ratio, large electrical endurance and enhanced lifetime, without any crosstalk between adjacent memory cells. The as-fabricated device showed excellent durability for several bending cycles at various bending diameters without any degradation in bistable resistive states. The memory mechanism was deduced to be conductive filamentary; this was validated by illustrating the temperature dependence of bistable resistive states. Our obtained results pave the way for the execution of promising 2D material based next generation flexible and non-volatile memory (NVM) applications. (paper)

    The increased effort in recent years towards methods for computer aided design of reversible logic circuits has also lead to research in algorithms for optimising the resulting circuits; both with higher-level data structures and directly on the reversible circuits. To obtain structural patterns...... that can be replaced by a cheaper realisation, many direct algorithms apply so-called moving rules; a simple form of rewrite rules that can only swap gate order. In this paper we first describe the few basic rules that are needed to perform rewriting directly on reversible logic circuits made from general...... as problems based on our rewrite rules. Finally, we outline a path to generalising the rewrite rules by showing their forms for reversible control-gates. This can be used to expand our method to other gates such as the controlled-swap gate or quantum gates....

    Full Text Available The purpose of this article is to explore the mythical representations in two of the six short stories that make up Lourdes Ortiz's Voces de mujer (2007, previously published under the title Los motivos de Circe. It is well known that most rewritings of the classical myths have been faithful to the “official truth” of the original versions. But recent works in search of other meanings, have explored dimensions often hidden or blurred by the “official” version. This is the case of the short stories in this collection whose protagonists are six archetypal or mythical women and their respectful references to the biblical, Homeric and pictorial world: Eve, Circe, Penelope, Betsabé, Salomé and Gioconda. The perspective offered by Lourdes Ortiz about the history of these myths allows us to read the story from the point of view of her female heroines. As such, then, in this article I will focus on two female characters from the Homeric epic: Circe and Penelope.El propósito de este artículo es explorar las representaciones míticas en dos de los seis cuentos que componen Voces de mujer (2007, de Lourdes Ortiz, publicado anteriormente bajo el título Los Motivos de Circe.

    In this Letter a new functional integral representation for classical dynamics is introduced. It is achieved by rewriting the Liouville picture in terms of bosonic creation-annihilation operators and utilizing the standard derivation of functional integrals for dynamical quantities in the coherent states representation. This results in a new class of functional integrals which are exactly solvable and can be found explicitly when the underlying classical systems are integrable

    The double field theory action in the flux formulation is dimensionally reduced on a Calabi-Yau three-fold equipped with non-vanishing type IIB geometric and non-geometric fluxes. First, we rewrite the metric-dependent reduced DFT action in terms of quantities that can be evaluated without explicitly knowing the metric on the Calabi-Yau manifold. Second, using properties of special geometry we obtain the scalar potential of N=2 gauged supergravity. After an orientifold projection, this potential is consistent with the scalar potential arising from the flux-induced superpotential, plus an additional D-term contribution.

    Directory of Open Access Journals (Sweden)

    Stefano Nicosia

    2013-01-01

    Full Text Available Many authors in the last century offer us the possibility to look at romance through their rewriting of Italian tradition, but they also offer the possibility to look at rewriting through romance. A systematic examination of every single work would need an article itself. Here the focus is rather on the phenomenon and its implications with tradition and its transformations; and on the intellectual context where they take place. Despite the very core of the poetics of rewriting can be located between the Sixties and the Eighties, these palimpsests go further, into the Nineties. From Calvino, Manganelli and Sanguineti, to Celati, Bufalino and Santagata, we are able to look at different declensions of rewriting. Through these texts and the techniques they are built with, it is possible to verify the strength and the qualities of some cultural and intellectual practices, which can be related to a coherent Italian postmodern poetics, which operates through the reuse of traditional materials. These reuse should be seen – and this is one of the cues and conclusions the article would like to offer – as a vital way of reproducing stories and genres in the postmodern era.

    Type classes and type families are key ingredients in Haskell programming. Type classes were introduced to deal with ad-hoc polymorphism, although with the introduction of functional dependencies, their use expanded to type-level programming. Type families also allow encoding type-level functions......, now as rewrite rules. This paper looks at the interplay of type classes and type families, and how to deal with shortcomings in both of them. Furthermore, we show how to use families to simulate classes at the type level. However, type families alone are not enough for simulating a central feature...... of type classes: elaboration, that is, generating code from the derivation of a rewriting. We look at ways to solve this problem in current Haskell, and propose an extension to allow elaboration during the rewriting phase....

    1992-01-01

    In Germany, the private use of nuclear energy for peaceful uses is strictly regulated by a Nuclear Energy Act. Since its enactment back in 1959, this legislation has been overhauled five times - most recently in 1985. Now Klaus Toepfer, Germany's Federal Minister for the Environment, Protection of Nature, and Nuclear Safety, has set out to revise the Act for the sixth time. The present draft bill is intended to reorganise the back end of the nuclear fuel cycle; eliminate public promotion of nuclear power; clarify points of legal dispute. Of the draft bill's three aims, the last two are more parochial. The real novelty lies in the changes to the rules for the back end of the fuel cycle. First, the Federal Government proposes to abandon the priority given to spent fuel recycling. In future, direct disposal will be an equivalent option, and waste avoidance will have top priority. Intimately linked to the back end proposal is the Government's plan to load on the shoulders of nuclear operators the full responsibility for building and operating repositories for the final disposal of nuclear waste. The third aspect of Government's back end plans concerns decommissioning. At present, operators accumulate provisions over the plant lifetime, which for that purpose is estimated at 19 years. The provisions vary from plant to plant but are generally around DM1 billion and are tax free. Under the proposed regulations, this sum must be available from the first day of operation to cover the case of an early shutdown. In practice, this will increase the initial investment for a nuclear power plant in Germany by 10-20% and so make nuclear power less competitive. (author)

    Full Text Available The calculus of looping sequences is a formalism for describing the evolution of biological systems by means of term rewriting rules. We enrich this calculus with a type discipline to guarantee the soundness of reduction rules with respect to some biological properties deriving from the requirement of certain elements, and the repellency of others. As an example, we model a toy system where the repellency of a certain element is captured by our type system and forbids another element to exit a compartment.

  3. Between Buddhism and Science, Between Mind and Body

    Full Text Available Buddhism has been seen, at least since the Theravāda reform movements of the late nineteenth and early twentieth centuries, as particularly compatible with Western science. The recent explosion of Mindfulness therapies have strengthened this perception. However, the 'Buddhism' which is being brought into relation with science in the context of the Mindfulness movement has already undergone extensive rewriting under modernist influences, and many of the more critical aspects of Buddhist thought and practice are dismissed or ignored. The Mind and Life Institute encounters, under the patronage of His Holiness the Dalai Lama, present a different kind of dialogue, in which a Tibetan Buddhism which is only beginning to undergo modernist rewriting confronts Western scientists and scholars on more equal terms. However, is the highly sophisticated but radically other world of Tantric thought really compatible with contemporary science? In this article I look at problem areas within the dialogue, and suggest that genuine progress is most likely to come if we recognise the differences between Buddhist thought and contemporary science, and take them as an opportunity to rethink scientific assumptions.

    Full Text Available Since the beginning of the 21st century, different Brazilian publishing houses have released Charles Perrault’s Stories or Tales of Olden Days with Morals in editions which present rewritings of the 17th century French author’s tales done by translators and adaptors of great prestige in the translation area or in children’s literature: Mário Laranjeira (Iluminuras, 2007, Maria Luiza Borges (Zahar, 2010, Ivone Benedetti (L&PM, 2012, Rosa Freire d’Aguiar (Companhia das Letrinhas, 2012, Katia Canton (DCL, 2005 and Walcyr Carrasco (Manole, 2009; Moderna, 2013. Besides promoting a rediscovery of the author by the Brazilian reading public, these rewritings – translations and adaptations – also help to promote and value his work, with editions that contain paratexts commenting on Perrault’s life and work as well as on the work done by the translator or adaptor. Considering the visibility of the translator/adaptor’s work provided by the paratexts that accompany the rewritings, this article discusses how a new publishing project is able to resignify a rewriting, in this case, Walcyr Carrasco's adaptation of Perrault’s tales, first launched by Manole (2009 and now in a new edition published by Moderna (2013, with a preface written by Regina Zilberman.

    2017-08-01

    The aim of this study is to investigate the frequency of electrosurgery-related pacemaker malfunction. A retrospective study was conducted to investigate electrosurgery-related pacemaker malfunction in consecutive patients undergoing pulse generator (PG) replacement or upgrade from two large hospitals in Minneapolis, MN between January 2011 and January 2014. The occurrence of this pacemaker malfunction was then studied by using MAUDE database for all four major device vendors. A total of 1398 consecutive patients from 2 large tertiary referral centers in Minneapolis, MN undergoing PG replacement or upgrade surgery were retrospectively studied. Four patients (0.3% of all patients), all with pacemakers from St Jude Medical (2.8%, 4 of 142) had output failure or inappropriately low pacing rate below 30 bpm during electrosurgery, despite being programmed in an asynchronous mode. During the same period, 1174 cases of pacemaker malfunctions were reported on the same models in MAUDE database, 37 of which (3.2%) were electrosurgery-related. Twenty-four cases (65%) had output failure or inappropriate low pacing rate. The distribution of adverse events was loss of pacing (59.5%), reversion to backup pacing (32.4%), inappropriate low pacing rate (5.4%), and ventricular fibrillation (2.7%). The majority of these (78.5%) occurred during PG replacement at ERI or upgrade surgery. No electrosurgery-related malfunction was found in MAUDE database on 862 pacemaker malfunction cases during the same period from other vendors. Electrosurgery during PG replacement or upgrade surgery can trigger output failure or inappropriate low pacing rate in certain models of modern pacemakers. Cautions should be taken for pacemaker-dependent patients.

    Full Text Available Here we tackle a problem from biology in terms of discrete mathematics. We are interested in a complex DNA manipulation process happening in eukaryotic organisms of a subclass of ciliate species called {\\it Stichotrichia} during so-called gene assembly. This process is in particular interesting since one can interpret gene assembly in ciliates as sorting of permutations. We survey here results related to studies on sorting permutations with some specific rewriting rules that formalize elementary intramolecular gene assembly operations. The research question is ``what permutation may be sorted with our operations?"

    2009-04-01

    Laser induced fluorescence imaging using excitation in ultraviolet (UV) wavelengths has been proposed as a nondestructive astrobiological rapid survey tool to search for amino and nucleic acids [1], microbial life [2], and polycyclic aromatic hydrocarbons (PAHs) deep in the Mars regolith [3, 4]. However, the technique is easily adapted to search for complex biomolecular targets using longer wavelength sources [5]. Of particular interest is the ability of excitation at 532 nm to detect photosynthetic pigments in cyanobacteria-dominated microbial communities populating the ice of alpine, Arctic, and Antarctic lakes, glaciers, and ice sheets [6-8]. During the months of November and December 2008 we tested the technique as part of an extended international, interdisciplinary field campaign in the Dry Valleys of Schirmacher Oasis and Lake Untersee, Queen Maud Land, Antarctica. In this paper we review our recent laboratory experiments on the use of UV excitation for detection of PAHs doped on Mars analogue soils [9] and chasmo- and epilithic lichen communities within basaltic Iceland lavas. We present for the first time the results of our field experiments conducted during the Tawani 2008 International Antarctic Expedition for in situ detection and quantification of photosynthetic biomass in the ice caps of annual and perennially ice-covered Antarctic lakes. We discuss the advantages of using a nondestructive rapid survey photonic tools such as laser induced fluorescence imaging that can be easily implemented from lander, rover, airborne, or orbital platforms. The techniques presented can be utilized to monitor the microbial potential of large, critical ecosystems on Earth, or to facilitate the remote or manned search for organics and photosynthetic life on any terrestrial planet.

    Full Text Available Political rewritings of the Our Father prayer in four Afrikaans poems. The utilisation of religious elements is a prominent trend in Afrikaans poetry − often in service of the political struggle, for example during the apartheid years. In this article four rewritings of the “Our Father” prayer are examined, using Linda Hutcheon’s theory of parody, as discussed in (among others, her pioneering work, “A theory of parody” (2000. For Hutcheon, parody does not necessarily imply ridiculing a previous text. According to her well-known definition, parody is “ironic transcontextualization, is repetition with difference. A critical distance is implied between the backgrounded text being parodied and the new incorporating work, a distance usually signaled by irony.” The rewritings of the “Our Father” by Jan Blom (Breyten Breytenbach, Ronnie Belcher and André Letoit (Koos Kombuis are distinct examples of ironic inversion, while in Hans du Plessis’s poem (in Griqua Afrikaans the irony is less obvious and the critique (if any more subdued. As Hutcheon explains and motivates, parody does not always take place at the expense of the parodied text. Thus the parodical rewritings of the “Our Father” need not necessarily be seen as destructive and belittling of the prayer itself, but as critically constructive vis-à-vis the Christian community.

  1. Dual DNA methylation patterns in the CNS reveal developmentally poised chromatin and monoallelic expression of critical genes.

    Directory of Open Access Journals (Sweden)

    Jinhui Wang

    Full Text Available As a first step towards discovery of genes expressed from only one allele in the CNS, we used a tiling array assay for DNA sequences that are both methylated and unmethylated (the MAUD assay. We analyzed regulatory regions of the entire mouse brain transcriptome, and found that approximately 10% of the genes assayed showed dual DNA methylation patterns. They include a large subset of genes that display marks of both active and silent, i.e., poised, chromatin during development, consistent with a link between differential DNA methylation and lineage-specific differentiation within the CNS. Sixty-five of the MAUD hits and 57 other genes whose function is of relevance to CNS development and/or disorders were tested for allele-specific expression in F(1 hybrid clonal neural stem cell (NSC lines. Eight MAUD hits and one additional gene showed such expression. They include Lgi1, which causes a subtype of inherited epilepsy that displays autosomal dominance with incomplete penetrance; Gfra2, a receptor for glial cell line-derived neurotrophic factor GDNF that has been linked to kindling epilepsy; Unc5a, a netrin-1 receptor important in neurodevelopment; and Cspg4, a membrane chondroitin sulfate proteoglycan associated with malignant melanoma and astrocytoma in human. Three of the genes, Camk2a, Kcnc4, and Unc5a, show preferential expression of the same allele in all clonal NSC lines tested. The other six genes show a stochastic pattern of monoallelic expression in some NSC lines and bi-allelic expression in others. These results support the estimate that 1-2% of genes expressed in the CNS may be subject to allelic exclusion, and demonstrate that the group includes genes implicated in major disorders of the CNS as well as neurodevelopment.

  2. Symbol manipulation and rule learning in spiking neuronal networks.

    2011-04-21

    It has been claimed that the productivity, systematicity and compositionality of human language and thought necessitate the existence of a physical symbol system (PSS) in the brain. Recent discoveries about temporal coding suggest a novel type of neuronal implementation of a physical symbol system. Furthermore, learning classifier systems provide a plausible algorithmic basis by which symbol re-write rules could be trained to undertake behaviors exhibiting systematicity and compositionality, using a kind of natural selection of re-write rules in the brain, We show how the core operation of a learning classifier system, namely, the replication with variation of symbol re-write rules, can be implemented using spike-time dependent plasticity based supervised learning. As a whole, the aim of this paper is to integrate an algorithmic and an implementation level description of a neuronal symbol system capable of sustaining systematic and compositional behaviors. Previously proposed neuronal implementations of symbolic representations are compared with this new proposal. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2009-11-01

    Full Text Available In Nice Work, David Lodge appropriates the model of the « condition-of-England novel » which he transposes into the 1980s. More than a mere transposition, Nice Work turns out to be an open rewriting of the Victorian novels quoted in epigraphs since the text, with its comical aspect and its auto-reflexive dimension, distances itself from realism. Far from being innocent, this rewriting considers critically the Thatcher era as well as contemporary literary theory and gives a discerning homage to Victorian novels.

    Full Text Available Translation seems to play a more important role in the development of culture than is generally supposed. Jorge Luis Borges is one writer who understood this phenomenon particularly well and in his writings translation gains in dignity. In a very original way, Borges considers the corpus of translated texts not inferior but even superior, to their prestigious originals, as it happens with the many versions of the Odyssey in English. Translation is also central to Borges’s poetics, where rereading and rewriting are essential. Keywords: Borges, translation, original, rereading, rewriting.

    2010-11-01

    The universal nilpotent computational rewrite system (UNCRS) is shown to formalize an irreversible process of evolution in conformity with the First, Second and Third Laws of Thermodynamics, in terms of a single algebraic creation operator (ikE+ip+jm) which delivers the whole quantum mechanical language apparatus, where k, i, j are quaternions units and E, p, m are energy, momentum and rest mass. This nilpotent evolution describes `a dynamic zero totality universe' in terms of its fermion states (each of which, by Pauli exclusion, is unique and nonzero), where, together with their boson interactions, these define physics at the fundamental level. (The UNCRS implies that the inseparability of objects and fields in the quantum universe is based on the fact that the only valid mathematical representations are all automorphisms of the universe itself, and that this is the mathematical meaning of quantum entanglement. It thus appears that the nilpotent fermion states are in fact what is called the splitting field in Quantum Mechanics of the Galois group which leads to the roots of the corresponding algebraic equation, and concerns in this case the alternating group of even permutations which are themselves automorphisms). In the nilpotent evolutionary process: (i) the Quantum Carnot Engine (QCE) extended model of thermodynamic irreversibility, consisting of a single heat bath of an ensemble of Standard Model elementary particles, retains a small amount of quantum coherence / entanglement, so as to constitute new emergent fermion states of matter, and (ii) the metric (E2-p2m2) = 0 ensures the First Law of the conservation of energy operates at each nilpotent stage, so that (iii) prior to each creation (and implied corresponding annihilation / conserve operation), E and m can be postulated to constitute dark energy and matter respectively.

    Full Text Available This paper addresses the topic of rewriting in journalistic discourse by examining the typical textual features of the press release, one of the most commonly used journalistic sources. Journalism has long being recognised as being based on reproductive writing practices (Jakobs 2003, as it consists, as Bell (1991: 41 puts it, “of previously composed text reworked into text news”. In this process of rewriting, a key role is played by sources. While their use (and occasional manipulation on the part of journalists has been variously explored in the literature, less has been done to investigate the textual features of documents specifically designed to serve as sources, most notably press releases. The paper provides a description of the characterising features of the genre of the press release, highlighting the essentially “preformulated” nature (Jacobs 1999 of these documents, i.e. the fact that their formal traits, as well as the structuring of their content, are strategically designed to facilitate reproduction. The paper concludes that while the re-use of textual material from sources is a crucial aspect of journalistic text production, care should be taken to distinguish between rewriting and uncritical textual reproduction: although recourse to the latter has been growing exponentially over the last decade due to an increasing shortening of news production cycles that has turned journalists into “processors rather than generators of news” (Lewis et al. 2008: 27 under constant pressure to continuously “churn out” (Davis 2008 stories, a renewed attention to rewriting as a key component of journalistic text production practices should be encouraged.

  15. FROM STORYTELLING TO STORY WRITING: THE IMPLEMENTATION OF READING TO LEARN (R2L PEDAGOGY TO TEACH ENGLISH AS A FOREIGN LANGUAGE IN INDONESIA

    Full Text Available It is widely acknowledged that the use of stories supports the development of literacy in the context of learning English as a first language. However, it seems that there are a few studies investigating this issue in the context of teaching and learning English as a foreign language.  This action-oriented case study aims to enhance students’ written narrative achievement through a pedagogical intervention that incorporates oral story sharing activities. In this paper, the intervention will be briefly described and the preliminary findings from the students’ written texts will be presented. This study which was conducted in a lower secondary school in Bandung Barat region, Indonesia implemented the intervention within eight learning periods. The intervention comprised the following stages: (1 preparing before reading (stories, (2 detailed reading, (3 joint rewriting, and (4 individual rewriting. Before and after the intervention, students’ narrative texts were collected and analysed in terms of how each text achieved its purpose, how it moved through stages and phases of meaning, the control of field, relationship with the reader and its coherence.  The preliminary findings indicate that there is a shift in students’ ability from writing fragmented and spoken-like language to more literate written narratives.   It is expected that this study which implemented R2L pedagogy in the Indonesian context will contribute to English language teaching in EFL contexts.

  16. Recipes

    1985-01-01

    Full Text Available After a distinction is made between avant-garde texts, post-modernist texts, and experimental texts, it is argued that the latter consist in the productions and products of recipes for textual rewritings. These rewritings must be systematic, bear on formal as opposed to contentual matters, and have as a dominant the exploration of writing rather than self or world. Furthermore, they may be more or less impersonal, explicit, massive, and new. To put it in other words, an experimental text is one that is taken to substitute the being of writing for the writing of being.

    2003-06-01

    Full Text Available This article has as a topic the revision of a text with the help of a Web page. Our question was, “What are the elements of the rewriting phase for a didactical sequence on fiction writing, when using computer tools, in this case to create a tale within a medieval setting?” We summarize the advantages of using a Web site for this, and we go on by tracing out the concepts that underlie rereading and rewriting the tale, and by listing the main objects to check during the revision process, completeness, coherence-cohesion, vocabulary, syntax and spelling.

  18. An algebraic method to solve the Tavis-Cummings problem

    International Nuclear Information System (INIS)

    Vadejko, I.P.; Miroshnichenko, G.P.; Rybin, A.V.; Timonen, J.

    2003-01-01

    We study cooperative behaviour of the system of two-level atoms coupled to a single mode of the electromagnetic field in the resonator. We have developed a general procedure allowing one to rewrite a polynomial deformed SU(2) algebra in terms of another polynomial deformation. Using these methods, we have constructed a perturbation series for the Tavis-Cummings Hamiltonian and diagonalized it in the third order. Based on the zero-order Hamiltonian we calculate the intensity of spontaneous emission of N two-level atoms inside a cavity, which are in thermal equilibrium with the reservoir. The atom-atom correlation determining superradiance in the system is analyzed

    Scattering amplitudes in Yang–Mills theory can be represented in the formalism of Cachazo, He and Yuan (CHY) as integrals over an auxiliary projective space—fully localized on the support of the scattering equations. Because solving the scattering equations is difficult and summing over the solutions algebraically complex, a method of directly integrating the terms that appear in this representation has long been sought. We solve this important open problem by first rewriting the terms in a manifestly Möbius-invariant form and then using monodromy relations (inspired by analogy to string theory) to decompose terms into those for which combinatorial rules of integration are known. The result is the foundations of a systematic procedure to obtain analytic, covariant forms of Yang–Mills tree-amplitudes for any number of external legs and in any number of dimensions. As examples, we provide compact analytic expressions for amplitudes involving up to six gluons of arbitrary helicities.

  20. Homogenization of the evolution Stokes equation in a perforated domain with a stochastic Fourier boundary condition

    KAUST Repository

    Bessaih, Hakima

    2015-04-01

    The evolution Stokes equation in a domain containing periodically distributed obstacles subject to Fourier boundary condition on the boundaries is considered. We assume that the dynamic is driven by a stochastic perturbation on the interior of the domain and another stochastic perturbation on the boundaries of the obstacles. We represent the solid obstacles by holes in the fluid domain. The macroscopic (homogenized) equation is derived as another stochastic partial differential equation, defined in the whole non perforated domain. Here, the initial stochastic perturbation on the boundary becomes part of the homogenized equation as another stochastic force. We use the twoscale convergence method after extending the solution with 0 in the holes to pass to the limit. By Itô stochastic calculus, we get uniform estimates on the solution in appropriate spaces. In order to pass to the limit on the boundary integrals, we rewrite them in terms of integrals in the whole domain. In particular, for the stochastic integral on the boundary, we combine the previous idea of rewriting it on the whole domain with the assumption that the Brownian motion is of trace class. Due to the particular boundary condition dealt with, we get that the solution of the stochastic homogenized equation is not divergence free. However, it is coupled with the cell problem that has a divergence free solution. This paper represents an extension of the results of Duan and Wang (Comm. Math. Phys. 275:1508-1527, 2007), where a reaction diffusion equation with a dynamical boundary condition with a noise source term on both the interior of the domain and on the boundary was studied, and through a tightness argument and a pointwise two scale convergence method the homogenized equation was derived. © American Institute of Mathematical Sciences.

    transformations as meta-reductions, i.e., reductions in the internal “substitution calculus.” For partial-evaluation problems, this means that instead of having to prove on a case-by-case basis that one's “two-level functions” operate properly, one can concisely formalize them as a combinatory reduction system...... and obtain as a corollary that static reduction does not go wrong and yields a well-formed residual program. We have found that the CRS substitution calculus provides an adequate expressive power to formalize partial evaluation: it provides sufficient termination strength while avoiding the need...

  6. On the fairlie's Moyal formulation of M(atrix)-theory

    2000-07-01

    Starting from the Moyal formulation of M-theory in the large N-limit, we propose to reexamine the associated membrane equations of motion in 10 dimensions formulated in terms of Poisson bracket. Among the results obtained, we rewrite the coupled first order Nahm's equations into a simple form leading in turn to their systematic relation with SU(∞) Yang Mills equations of motion. The former are interpreted as the vanishing condition of some conserved currents which we propose. We also develop an algebraic analysis in which an ansatz is considered and find an explicit form for the membrane solution of our problem. Typical solutions known in literature can also emerge as special cases of the proposed solution. (author)

  7. On Tree Pattern Matching by Pushdown Automata

    Directory of Open Access Journals (Sweden)

    T. Flouri

    2009-01-01

    Full Text Available Tree pattern matching is an important operation in Computer Science on which a number of tasks such as mechanical theorem proving, term-rewriting, symbolic computation and non-procedural programming languages are based on. Work has begun on a systematic approach to the construction of tree pattern matchers by deterministic pushdown automata which read subject trees in prefix notation. The method is analogous to the construction of string pattern matchers: for given patterns, a non-deterministic pushdown automaton is created and then it is determinised. In this first paper, we present the proposed non-deterministic pushdown automaton which will serve as a basis for the determinisation process, and prove its correctness.

    Wide reactive systems are rewriting systems specified by wide reaction rules, where redex and reactum are lists of terms (forests), i.e. rules of the form ⟨l1(x1),…,ln(xn)⟩⇒⟨r1(y1),…,rn(yn)⟩ such that ∪iyi⊆∪ixi. Wide reaction rules are particularly useful for process calculi for mobile and global...... system), possibly finding the subtrees to be grafted at the forest’s leaves (i.e., instantiating the variables)?

  9. Audre's daughter: Black lesbian steganography in Dee Rees' Pariah and Audre Lorde's Zami: A New Spelling of My Name.

    Science.gov (United States)

    Kang, Nancy

    2016-01-01

    This article argues that African-American director Dee Rees' critically acclaimed debut Pariah (2011) is a rewriting of lesbian poet-activist Audre Lorde's iconic "bio-mythography" Zami: A New Spelling of My Name (1982). The article examines how Rees' work creatively and subtly re-envisions Lorde's Zami by way of deeply rooted and often cleverly camouflaged patterns, resonances, and contrasts. Shared topics include naming, mother-daughter bonds, the role of clothing in identity formation, domestic abuse, queer time, and lesbian, gay, bisexual, and transgender legacy discourse construction. What emerges between the visual and written texts is a hidden language of connection--what may be termed Black lesbian steganography--which proves thought-provoking to viewers and readers alike.

  11. A critique of recent models for human error rate assessment

    International Nuclear Information System (INIS)

    Apostolakis, G.E.

    1988-01-01

    This paper critically reviews two groups of models for assessing human error rates under accident conditions. The first group, which includes the US Nuclear Regulatory Commission (NRC) handbook model and the human cognitive reliability (HCR) model, considers as fundamental the time that is available to the operators to act. The second group, which is represented by the success likelihood index methodology multiattribute utility decomposition (SLIM-MAUD) model, relies on ratings of the human actions with respect to certain qualitative factors and the subsequent derivation of error rates. These models are evaluated with respect to two criteria: the treatment of uncertainties and the internal coherence of the models. In other words, this evaluation focuses primarily on normative aspects of these models. The principal findings are as follows: (1) Both of the time-related models provide human error rates as a function of the available time for action and the prevailing conditions. However, the HCR model ignores the important issue of state-of-knowledge uncertainties, dealing exclusively with stochastic uncertainty, whereas the model presented in the NRC handbook handles both types of uncertainty. (2) SLIM-MAUD provides a highly structured approach for the derivation of human error rates under given conditions. However, the treatment of the weights and ratings in this model is internally inconsistent. (author)

  12. The Circulation of Shakespeare Adaptations in Eastern Europe

    Directory of Open Access Journals (Sweden)

    Nicolaescu Mădălina

    2014-02-01

    Full Text Available The paper discusses the stage adaptations of Shakespeare's Hamlet and Romeo and Juliet that were circulated in the German Länders and the Habsburg Empire in the late 18th and early 19th century. The various forms of re-writing Shakespeare are linked with processes re-contextualizing the text and are discussed as forms of localizing a transnational Shakespeare. The analysis zooms in on the contexts of performance of the German adaptations in two Transylvanian cities. The paper highlights the cultural and linguistic negotiations performed when further translating the already multilayered rewritings of the Shakespearean text and focuses on a Romanian translation of a German adaptation of Hamlet.

The calculus has since been extended to dependent types by Møgelberg. Both works give denotational semantics but no rewrite semantics....... In previous versions of this calculus, different clocks represented separate time streams and clock synchronisation was prohibited. In this paper we show that allowing clock synchronisation is safe by constructing a new model of guarded recursion and clocks. This result will greatly simplify the type theory...... by removing freshness restrictions from typing rules, and is a necessary step towards defining rewrite semantics, and ultimately implementing the calculus....

  18. Generalized metric formulation of double field theory on group manifolds

    International Nuclear Information System (INIS)

    Blumenhagen, Ralph; Bosque, Pascal du; Hassler, Falk; Lüst, Dieter

    2015-01-01

    We rewrite the recently derived cubic action of Double Field Theory on group manifolds http://dx.doi.org/10.1007/JHEP02(2015)001 in terms of a generalized metric and extrapolate it to all orders in the fields. For the resulting action, we derive the field equations and state them in terms of a generalized curvature scalar and a generalized Ricci tensor. Compared to the generalized metric formulation of DFT derived from tori, all these quantities receive additional contributions related to the non-trivial background. It is shown that the action is invariant under its generalized diffeomorphisms and 2D-diffeomorphisms. Imposing additional constraints relating the background and fluctuations around it, the precise relation between the proposed generalized metric formulation of DFT WZW and of original DFT from tori is clarified. Furthermore, we show how to relate DFT WZW of the WZW background with the flux formulation of original DFT.

  19. A Convex Optimization Model and Algorithm for Retinex

    Directory of Open Access Journals (Sweden)

    Qing-Nan Zhao

    2017-01-01

    Full Text Available Retinex is a theory on simulating and explaining how human visual system perceives colors under different illumination conditions. The main contribution of this paper is to put forward a new convex optimization model for Retinex. Different from existing methods, the main idea is to rewrite a multiplicative form such that the illumination variable and the reflection variable are decoupled in spatial domain. The resulting objective function involves three terms including the Tikhonov regularization of the illumination component, the total variation regularization of the reciprocal of the reflection component, and the data-fitting term among the input image, the illumination component, and the reciprocal of the reflection component. We develop an alternating direction method of multipliers (ADMM to solve the convex optimization model. Numerical experiments demonstrate the advantages of the proposed model which can decompose an image into the illumination and the reflection components.

  20. A new repeatable, optical writing and electrical erasing device based on photochromism and electrochromism of viologen

    Gao, Li-ping; Wei, Jian; Wang, Yue-chuan; Ding, Guo-jing; Yang, Yu-lin

    2012-01-01

    New optical writing and electrical erasing devices have been successfully fabricated that exploit the photochromism and electrochromism of viologen. In a preliminary study, both the structures of viologen and device were investigated in detail by UV–vis spectra in order to confirm their effects on the optical writing and electrical erasing performances of corresponding devices. For sandwiched, single and complementary devices based on benzyl viologen (BV 2+ ), only optical writing can be performed, not electrical erasing operations, which indicated these devices cannot realize optical information rewriting. For single and complementary devices based on styrene-functional viologen (V BV 2+ ) and acrylic-functional viologen (ACV 2+ ), optical writing and electrical erasing operations can be reversibly performed and optical information rewriting realized. It is clear that single devices based on V BV 2+ and ACV 2+ possess better performance accompanied with contrast without significant degradation and bleaching times and without significant deterioration over 10 repeated writing/erasing cycles. Furthermore, we put forward possible mechanisms for sandwiched, single and complementary devices based on V BV 2+ and ACV 2+ for the optical writing and electrical erasing operations. This study provides a new strategy to design optical writing and electrical erasing devices to realize optical information rewriting. (paper)

    Full Text Available The aim of this study is to show the presence of classical epic, Homer's Iliad, in the chronicle of Machado de Assis, analyzing the intertextual dialogue between Machado de Assis and the epic poem by Homer, considering the concept of intertextuality developed by Julia Kristeva from philosophical conceptions of Bakhtin. In the chronicle of March 18, 1894 for the newspaper Gazeta de Notícias on sunday column "A Semana", Machado de Assis crosses Homer's epic to his chronicle, rewrites the epic text for the daily issues of his weekly column. To Tiphaine Samoyault, writing is rewriting, "stand on the existing foundations and contribute to a continued creation" (2008, p. 77 one of the principles of intertextuality. It was observed that from the reading and assimilation of the classic poem, Machado de Assis can approach so far genres, bringing the verses to his prose, leaving it closer to poetry. In this sense, we can see the richness of Machado de Assis chronicles, often left on the sidelines in favor of his short stories and romances. In addition, the dialogue, to rewrite the epic in his chronicle, Machado seems to contribute to this "continuous creation", reviving the memory of literature and emphasizing the permanence of classical work.

    Many free-stall bovine dairy herds in Norway fail to eradicate Streptococcus agalactiae despite long-term control measures. In a longitudinal study of 4 free-stall herds with automatic milking systems (AMS), milk and extramammary sites were sampled 4 times with 1-2 month intervals. Composite milk, rectal- and vaginal swabs were collected from dairy cows; rectal swabs from heifers and young stock; rectal- and tonsillar swabs from calves; and environmental swabs from the AMS, the floors, cow beds, watering and feeding equipment. A cross sectional study of 37 herds was also conducted, with 1 visit for environmental sampling. Fifteen of the herds were known to be infected with S. agalactiae while the remaining 22 had not had evidence of S. agalactiae mastitis in the preceding 2 years. All samples were cultured for S. agalactiae, and selected isolates (n=54) from positive herds were genotyped by Multi Locus Sequence Typing (MLST). Results show that the bovine gastrointestinal tract and the dairy cow environment are reservoirs of S. agalactiae, and point to the existence of 2 transmission cycles; a contagious transmission cycle via the milking machine and an oro-fecal transmission cycle, with drinking water as the most likely vehicle for transmission. Ten sequence types were identified, and results suggest that strains differ in their ability to survive in the environment and transmit within dairy herds. Measures to eradicate S. agalactiae from bovine dairy herds should take into account the extra-mammary reservoirs and the potential for environmental transmission of this supposedly exclusively contagious pathogen.

The authors distinguish the stages of realization of audit of long-term and short-term liabilities, the aim of audit on each of the presented stages, and recommend methodical techniques. It is fixed that it is necessary to conduct the estimation of the systems of internal control and record-keeping of an enterprise by implementation of public accountant procedures for determination of volume and maintenance of selection realization. After estimating the indicated systems, a public accountant determines the methodology for realization of public accountant verification of long-term and short-term liabilities. The analytical procedures that public accountants are expedient to use for realization of audit of short-term and long-term obligations are determined. The authors suggest the classification of the educed defects on the results of the conducted public accountant verification of short-term and long-term obligations.

    We present a multifunctional and multistate permanent memory device based on lateral electric field control of a strained surface. Sub-coercive electrical writing of a remnant strain of a PZT substrate imprints stable and rewritable resistance changes on a CoFe overlayer. A proof-of-principle device, with the simplest resistance strain gage design, is shown as a memory cell exhibiting 17-memory states of high reproducibility and reliability for nonvolatile operations. Magnetoresistance of the film also depends on the cell state, and indicates a rewritable change of magnetic properties persisting in the remnant strain of the substrate. This makes it possible to combine strain, magnetic and resistive functionalities in a single memory element, and suggests that sub-coercive stress studies are of interest for straintronics applications.

    We show that the partition functions which enumerate Donaldson-Thomas invariants of local toric Calabi-Yau threefolds without compact divisors can be expressed in terms of specializations of the Schur measure. We also discuss the relevance of the Hall-Littlewood and Jack measures in the context of BPS state counting and study the partition functions at arbitrary points of the Kaehler moduli space. This rewriting in terms of symmetric functions leads to a unitary one-matrix model representation for Donaldson-Thomas theory. We describe explicitly how this result is related to the unitary matrix model description of Chern-Simons gauge theory. This representation is used to show that the generating functions for Donaldson-Thomas invariants are related to tau-functions of the integrable Toda and Toeplitz lattice hierarchies. The matrix model also leads to an interpretation of Donaldson-Thomas theory in terms of non-intersecting paths in the lock-step model of vicious walkers. We further show that these generating functions can be interpreted as normalization constants of a corner growth/last-passage stochastic model.

    2007-01-01

    We address the discretization of the Levermore's two moments and entropy model of the radiative transfer equation. We present a new approach for the discretization of this model: first we rewrite the moment equations as a Compressible Gas Dynamics equation by introducing an additional quantity that plays the role of a density. After that we discretize using a Lagrange-projection scheme. The Lagrange-projection scheme permits us to incorporate the source terms in the fluxes of an acoustic solver in the Lagrange step, using the well-known piecewise steady approximation and thus to capture correctly the diffusion regime. Moreover we show that the discretization is entropic and preserve the flux-limited property of the moment model. Numerical examples illustrate the feasibility of our approach. (authors)

  11. New Massive Gravity and AdS4 Counterterms

    2011-01-01

    We show that the recently proposed Dirac-Born-Infeld extension of new massive gravity emerges naturally as a counterterm in four-dimensional anti-de Sitter space (AdS 4 ). The resulting on-shell Euclidean action is independent of the cutoff at zero temperature. We also find that the same choice of counterterm gives the usual area law for the AdS 4 Schwarzschild black hole entropy in a cutoff-independent manner. The parameter values of the resulting counterterm action correspond to a c=0 theory in the context of the duality between AdS 3 gravity and two-dimensional conformal field theory. We rewrite this theory in terms of the gauge field that is used to recast 3D gravity as a Chern-Simons theory.

    We study the SO(8) superconformal theory proposed recently by Bagger and Lambert as a possible worldvolume theory for multiple M2-branes. For their explicit example with gauge group SO(4), we rewrite the theory (originally formulated in terms of a three-algebra) as an ordinary SU(2) x SU(2) gauge theory with bifundamental matter. In this description, the parity invariance of the theory, required for a proper description of M2-branes, is clarified. We describe the subspace of scalar field configurations on which the potential vanishes, correcting an earlier claim. Finally, we point out, for general three-algebras, a difficulty in constructing the required set of superconformal primary operators which should be present in the correct theory describing multiple M2-branes.

    Full Text Available The term metropolis has a double meaning: it indicates the motherland in the colonialist historical movement and, at the same time, the urban conglomerate that characterizes our postmodernity. The theoretical link between the two meanings can generate a postcolonial critique and an intercultural analysis of our multicultural metropolis, exposed to differences and multiple identifications. At the same time, the metropolitan condition shows us how the contact between the differences is now intra-cultural and no longer inter-cultural, proposing a political rewrite of Intercultural Pedagogy as a plural and materialistic Differences Pedagogy, able to recognize the characteristics of struggle for survival and of cultural creativity that today seem unite indigenous and migrants taking the floor in our cities.

  15. ‘Making and remaking history: categorising ‘conceptual art’ in contemporary Chinese art’

    Directory of Open Access Journals (Sweden)

    Peggy Wang

    2014-06-01

    Full Text Available During the 1990s, curators and critics embraced conceptual art as a category for legitimizing Chinese art’s global and contemporary status. Conceptual art’s ambiguous parameters, critical cachet, and penchant for destabilization offered unprecedented opportunities for demonstrating Chinese art as globally relevant without being imitative, historical without being traditional, and resistant without being reduced to ‘dissident’. In order to apply the label, however, authors necessarily contended with post-colonial anxieties about imported terms and frameworks. This paper examines how curators and critics of contemporary Chinese art turned to writing and rewriting history—through constructed strategic lineages and cross-cultural comparisons—in order to accommodate the category of conceptual art in their claims for global parity.

  16. Some empirical rules concerning the vapor pressure curve revisited

    Highlights: • A Claussius–Claperyron equation is obtained in the Pitzer corresponding states scheme. • Some well-known empirical rules for the vapor pressure are rewritten in terms of the Pitzer acentric factor. • The Guggenheim point follows the corresponding state scheme better than the normal boiling point. • The Ambrose–Walton vapor pressure equation yields excellent agreement with NIST data in all considered cases. -- Abstract: A form for the Clausius–Clapeyron vapor-pressure equation is obtained in the Pitzer corresponding states scheme. This equation allows one to rewrite the well-known Trouton, Guldberg, van Laar and Guggenheim rules in terms of the acentric factor ω. The original forms of these empirical rules are recovered for some particular values of ω. The proposed rules are checked by analyzing National Institute of Standards and Technology (NIST) data on the liquid-vapor coexistence curve for 105 fluids. These rules have been also analyzed by using the well-known Ambrose–Walton (AW) vapor pressure equation

    We rewrite the recently derived cubic action of Double Field Theory on group manifolds http://dx.doi.org/10.1007/JHEP02(2015)001 in terms of a generalized metric and extrapolate it to all orders in the fields. For the resulting action, we derive the field equations and state them in terms of a generalized curvature scalar and a generalized Ricci tensor. Compared to the generalized metric formulation of DFT derived from tori, all these quantities receive additional contributions related to the non-trivial background. It is shown that the action is invariant under its generalized diffeomorphisms and 2D-diffeomorphisms. Imposing additional constraints relating the background and fluctuations around it, the precise relation between the proposed generalized metric formulation of DFT{sub WZW} and of original DFT from tori is clarified. Furthermore, we show how to relate DFT{sub WZW} of the WZW background with the flux formulation of original DFT.

  18. Transverse instability excited by rf deflecting modes for PEP

    Chao, A.W.; Yao, C.Y.

    1979-11-01

    We have looked at the possible transverse instability effects which are caused by the deflecting modes of the rf cavities in PEP. The results are obtained by applying the expression of the instability damping rate. We have assumed that there equal bunches equally spaced in PEP. We have worked out the equivalent for a single bunch beam. The effect of chromaticity ξ is included as a frequency shift in the bunch mode spectra. We rewrite this result in terms of the transverse wake field instead of the impedance. We include an application of the Sacherer formalism to the case of resistive wall. The resulting expression of the damping rate contains two terms. The first term corresponds to the effect of the short wake fields; it agrees with the result of the head-tail instability as derived by Sands. A numerical estimate of this resistive-wall head tail case for PEP is given. It re-confirms that the resistive wall instability is not a serious problem for PEP. The second term gives the effect of long wake fields and it agrees with the result of Courant and Sessler. 10 refs., 2 figs

  19. Gauge invariant Lagrangian formulation of massive higher spin fields in (A)dS3 space

    We develop the frame-like formulation of massive bosonic higher spin fields in the case of three-dimensional (A)dS space with the arbitrary cosmological constant. The formulation is based on gauge invariant description by involving the Stueckelberg auxiliary fields. The explicit form of the Lagrangians and the gauge transformation laws are found. The theory can be written in terms of gauge invariant objects similar to the massless theories, thus allowing us to hope to use the same methods for investigation of interactions. In the massive spin 3 field example we are able to rewrite the Lagrangian using the new the so-called separated variables, so that the study of Lagrangian formulation reduces to finding the Lagrangian containing only half of the fields. The same construction takes places for arbitrary integer spin field as well. Further working in terms of separated variables, we build Lagrangian for arbitrary integer spin and write it in terms of gauge invariant objects. Also, we demonstrate how to restore the full set of variables, thus receiving Lagrangian for the massive fields of arbitrary spin in the terms of initial fields.

    Full Text Available The Alfred Wegener Institute operates two stations in Dronning Maud Land, Antarctica. The German overwintering station Neumayer III is located on the Ekström Ice Shelf at 70°40’S and 08°16’W and is the logistics base for three long-term observatories (meteorology, air chemistry and geophysics and nearby research activities. Due to the vicinity to the coast (ca. 20 km from the ice shelf edge, the Neumayer III Station is the junction for many German Antarctic expeditions, especially as the starting point for the supply traverse for the second German station Kohnen. The summer station Kohnen is located about 600 km from the coast and 750 km from Neumayer III Station on the Antarctic plateau at 75°S and 00°04’E. It was erected as the base for the deep-drilling ice core project, which took place between 2001 and 2006. Since then Kohnen Station is used as a logistics base for different research projects.

    International Nuclear Information System (INIS)

    Woodman, B.

    2009-01-01

    From ends of the ninety, the new nuclear energy has been rejected three times like an option of viable energy generation for United Kingdom: once during the privatization of the electric supply industry and twice during the subsequent revisions to the energy politicians carried out in 2003. Nevertheless, three years more late, a new debate around the energy politics gave an unusual turning in the industry destination, characterized by the firm consideration in the political calendar about the new reactors development, as well as of governmental politicians guided to impel it. This recent interest arises of restlessness regarding the future security of the supply and to the necessity of reducing the carbon dioxide emissions of United Kingdom. With the purpose of obtaining the sufficient support of civil politicians and investors for the new construction project, the industry will have to devise convincing arguments to prove that it has already solved those problems that it suffered in the past and, also that deserves to receive a special treatment in the liberated market of the electricity. This document synthesizes the structure of the nuclear industry in United Kingdom, some recent historical data and the reasons for those that the new nuclear reactors were not very received in the past. It also indicates the measures that have taken in recent times to modify that perspective. Finally, it analyzes the possible future of the nuclear energy at long term in United Kingdom. (Author)

  7. Aspects of AdS, CFT. Black solutions in gauged supergravity and holographic conductivities

    International Nuclear Information System (INIS)

    Barisch-Dick, Susanne

    2013-01-01

    We have met some interesting results within the wide subject of the AdS/CFT correspondence. We have seen how to apply AdS/CFT techniques to calculate the frequency dependent conductivity tensor for field theories dual to a black hole in Einstein-Yang-Mills theory with SU(2) gauge group. Further, we have constructed several new black solutions in N=2 U(1) gauged supergravity in four and five dimensions. The larger part of these solutions behave asymptotically like AdS which makes them interesting within the AdS/CFT context. In addition we found extremal black branes with zero entropy density - the Nernst branes. Nonetheless we are left with some yet unsolved problems. It is very interesting to see what causes the negative entropy production rate we found in chapter 4 for the normal state of the field theory. The next task is to see whether we can find an instability on the gravity side looking at the full Einstein-Yang-Mills equations. Also our work on supergravity solutions in four and five dimension exhibits some ''loose ends''. Since all our four-dimensional Nernst solutions were axion-free it would be nice to find one with axions excited. Moreover, it would be interesting to see whether the singular solutions with flowing γ could be cured by taking into account higher derivative corrections or whether there exist non-singular solutions with non-constant γ. In five dimensions we met problems when adding electric charge. At present we could not find a dyonic solution and we had the impression that having electric charges and having magnetic fields seemed to be somehow complementary to each other. We saw these difficulties even at the beginning when we performed the first-order rewriting since the first-order rewriting in chapter 6 leads to flow equations for the scalars X A which only contain magnetic fields and fluxes but no electric charges. The latter only influence the equations of motion for the X A in an indirect way. However it is possible to find

Earlier versions provided representations for neutron cross sections and distributions, photon production from neutron reactions, a limited amount of charged-particle production from neutron reactions, photo-atomic interaction data, thermal neutron scattering data, and radionuclide production and decay data (including fission products). This version allows higher incident energies, adds more complete descriptions of the distributions of emitted particles, and provides for incident charged particles and photo-nuclear data by partitioning the ENDF library into sublibraries. Decay data, fission product yield data, thermal scattering data, and photo-atomic data have also been formally placed in sublibraries.

Although inevitably limited in number, these studies take us a long way from the ‗originals‘ in their home culture, to mid-twentieth century Romania, to Orson Welles in the 1950‘s or the 2016 American elections, to Japanese contemporary manga or…to the opera, at different times in history, once again testifying to the amazing plurality of response Shakespeare‘s works have received. In addition, as is well known, these studies are all tiny fragments of the same gigantic puzzle that is called Shakespearian scholarship. The editors of this issue hope that the readers will find here new stimulating pieces of information in a field that will never cease to fascinate us.

For parallels to this phenomenon, Luz points to the story of Moses in Deuteronomy and that of the patriarchs in Jubilees.

    Full Text Available We compare the present and last interglacial periods as recorded in Antarctic water stable isotope records now available at various temporal resolutions from six East Antarctic ice cores: Vostok, Taylor Dome, EPICA Dome C (EDC, EPICA Dronning Maud Land (EDML, Dome Fuji and the recent TALDICE ice core from Talos Dome. We first review the different modern site characteristics in terms of ice flow, meteorological conditions, precipitation intermittency and moisture origin, as depicted by meteorological data, atmospheric reanalyses and Lagrangian moisture source diagnostics. These different factors can indeed alter the relationships between temperature and water stable isotopes. Using five records with sufficient resolution on the EDC3 age scale, common features are quantified through principal component analyses. Consistent with instrumental records and atmospheric model results, the ice core data depict rather coherent and homogenous patterns in East Antarctica during the last two interglacials. Across the East Antarctic plateau, regional differences, with respect to the common East Antarctic signal, appear to have similar patterns during the current and last interglacials. We identify two abrupt shifts in isotopic records during the glacial inception at TALDICE and EDML, likely caused by regional sea ice expansion. These regional differences are discussed in terms of moisture origin and in terms of past changes in local elevation histories, which are compared to ice sheet model results. Our results suggest that elevation changes may contribute significantly to inter-site differences. These elevation changes may be underestimated by current ice sheet models.

  4. Near-Term Actions to Address Long-Term Climate Risk

    Science.gov (United States)

    Lempert, R. J.

    2014-12-01

    Addressing climate change requires effective long-term policy making, which occurs when reflecting on potential events decades or more in the future causes policy makers to choose near-term actions different than those they would otherwise pursue. Contrary to some expectations, policy makers do sometimes make such long-term decisions, but not as commonly and successfully as climate change may require. In recent years however, the new capabilities of analytic decision support tools, combined with improved understanding of cognitive and organizational behaviors, has significantly improved the methods available for organizations to manage longer-term climate risks. In particular, these tools allow decision makers to understand what near-term actions consistently contribute to achieving both short- and long-term societal goals, even in the face of deep uncertainty regarding the long-term future. This talk will describe applications of these approaches for infrastructure, water, and flood risk management planning, as well as studies of how near-term choices about policy architectures can affect long-term greenhouse gas emission reduction pathways.

  5. Réécritures du mythe d’Orphée et enjeux esthétiques, philosophiques et formels dans The Mask of Orpheus de Harrison Birtwistle Aesthetic, Philosophical and Formal Questions Raised by the Rewritings of the Myth of Orpheus in Harrison Birtwistle’s The Mask of Orpheus

    Directory of Open Access Journals (Sweden)

    Jean-Philippe Héberlé

    2009-08-01

    Full Text Available This article deals with Harrison Birtwistle’s rewriting of the myth of Orpheus in his opera The Mask of Orpheus (1986. Written on a libretto by Peter Zinovieff, The Mask of Orpheus is part of a long tradition of operas dealing with the famous Greek myth. Yet, the way it is tackled by Birtwistle and Zinovieff is very different from what was done in the past. They do not present the spectator with the key elements of the story in a linear way but simultaneously. Different versions of the myth are introduced and sometimes we are presented with contradictory versions at the same time to force us to be active and aware of the existence of different kinds of dualities. The simultaneous presentation of some events is also connected to the way Birtwistle and Zinovieff play with the notion of time in their opera. One of their aims is to show how memory functions. When you remember something the frontier between past and present is blurred and the remembrance of things past is part of an endless cycle where things are perpetually brought to life, a very important aspect of myths whose universal and timeless nature is thus emphasized. Rituals, like myths, are based on the idea of repetition as well as on the idea of returning to the origins. This is why the opera may be considered as a ritualistic piece of work; this is underlined by the omnipresence of the figure three—a ritual number—in the literary and musical structure of The Mask of Orpheus.

    Directory of Open Access Journals (Sweden)

    Lucas Dixon

    2010-06-01

    Full Text Available We present a form of algebraic reasoning for computational objects which are expressed as graphs. Edges describe the flow of data between primitive operations which are represented by vertices. These graphs have an interface made of half-edges (edges which are drawn with an unconnected end and enjoy rich compositional principles by connecting graphs along these half-edges. In particular, this allows equations and rewrite rules to be specified between graphs. Particular computational models can then be encoded as an axiomatic set of such rules. Further rules can be derived graphically and rewriting can be used to simulate the dynamics of a computational system, e.g. evaluating a program on an input. Examples of models which can be formalised in this way include traditional electronic circuits as well as recent categorical accounts of quantum information.

    Full Text Available Resistive memories are considered the most promising candidates for the next generation of non-volatile memory; however, attention has so far been limited to rewritable memory features for applications in resistive random access memories (RRAM. In this article, we provide a new insight into the applicability of resistive memories. The characteristics of non-rewritable resistive memories (NRRM were investigated. Devices with Pt/ZnO/ITO architecture were prepared using magnetron sputtering, upon which various bipolar and unipolar resistive switching tests were performed. The results showed excellent distinction between the high resistance state (HRS and low resistance state (LRS, with RHRS/RLRS = 5.2 × 1011 for the Pt/ZnO/ITO device with deposition time of 1 h. All samples were stable for more than 104 s, indicating that the devices have excellent applicability in NRRMs.

    Full Text Available This article concerns the re-writing of an Irish historical moment within the short story genre, focusing on the renowned Irish writer Seán O’Faoláin (1900-1991. O’Faoláin, it is argued here, attempted to alleviate the “trauma” of the Irish Civil War (1922-1923 through his writing. This piece offers a comparative analysis of O’Faoláin’s treatment of the Civil War in his autobiography, Vive Moi! (1993, and in two short stories, “Fugue” and “The Bomb Shop”, from the collection Midsummer Night Madness (1932, examining his re-writing of several key episodes from the Civil War. As this article demonstrates, O’Faoláin re-wrote these so that they became part of a less contentious War of Independence narrative.

  12. Long-term associative learning predicts verbal short-term memory performance.

    Science.gov (United States)

    Jones, Gary; Macken, Bill

    2018-02-01

    Studies using tests such as digit span and nonword repetition have implicated short-term memory across a range of developmental domains. Such tests ostensibly assess specialized processes for the short-term manipulation and maintenance of information that are often argued to enable long-term learning. However, there is considerable evidence for an influence of long-term linguistic learning on performance in short-term memory tasks that brings into question the role of a specialized short-term memory system separate from long-term knowledge. Using natural language corpora, we show experimentally and computationally that performance on three widely used measures of short-term memory (digit span, nonword repetition, and sentence recall) can be predicted from simple associative learning operating on the linguistic environment to which a typical child may have been exposed. The findings support the broad view that short-term verbal memory performance reflects the application of long-term language knowledge to the experimental setting.

  9. Aspects of AdS, CFT. Black solutions in gauged supergravity and holographic conductivities

    Energy Technology Data Exchange (ETDEWEB)

    Barisch-Dick, Susanne

    2013-04-26

    We have met some interesting results within the wide subject of the AdS/CFT correspondence. We have seen how to apply AdS/CFT techniques to calculate the frequency dependent conductivity tensor for field theories dual to a black hole in Einstein-Yang-Mills theory with SU(2) gauge group. Further, we have constructed several new black solutions in N=2 U(1) gauged supergravity in four and five dimensions. The larger part of these solutions behave asymptotically like AdS which makes them interesting within the AdS/CFT context. In addition we found extremal black branes with zero entropy density - the Nernst branes. Nonetheless we are left with some yet unsolved problems. It is very interesting to see what causes the negative entropy production rate we found in chapter 4 for the normal state of the field theory. The next task is to see whether we can find an instability on the gravity side looking at the full Einstein-Yang-Mills equations. Also our work on supergravity solutions in four and five dimension exhibits some ''loose ends''. Since all our four-dimensional Nernst solutions were axion-free it would be nice to find one with axions excited. Moreover, it would be interesting to see whether the singular solutions with flowing γ could be cured by taking into account higher derivative corrections or whether there exist non-singular solutions with non-constant γ. In five dimensions we met problems when adding electric charge. At present we could not find a dyonic solution and we had the impression that having electric charges and having magnetic fields seemed to be somehow complementary to each other. We saw these difficulties even at the beginning when we performed the first-order rewriting since the first-order rewriting in chapter 6 leads to flow equations for the scalars X{sup A} which only contain magnetic fields and fluxes but no electric charges. The latter only influence the equations of motion for the X{sup A} in an indirect way. However

  16. Supergravity couplings to Noncommutative Branes, Open Wilson Lines and Generalised Star Products

    International Nuclear Information System (INIS)

    Das, S.R.; Trivedi, S.P.

    2001-01-01

    Noncommutative gauge theories can be constructed from ordinary U(∞) gauge theories in lower dimensions. Using this construction we identify the operators on noncommutative D-branes which couple to linearized supergravity backgrounds, from a knowledge of such couplings to lower dimensional D-branes with no B field. These operators belong to a class of gauge invariant observables involving open Wilson lines. Assuming a DBI form of the coupling we show, to second order in the gauge potential but to all orders of the noncommutativity parameter, that our proposal agrees with the operator obtained in terms of ordinary gauge fields by considering brane actions in backgrounds and then using the Seiberg-Witten map to rewrite this in terms of noncommutative gauge fields. Our result clarify why a certain commutative but non-associative 'generalized star product' appears both in the expansion of the open Wilson line, as well as in string amplitude computations of open string-closed string couplings. We outline how our procedure can be used to obtain operators in the noncommutative theory which are holographically dual to supergravity modes. (author)

    Electrophoretic display (EPD) is a non-luminous type display using electrophoresis of particles dispersing in a solvent. This kind of display is particularly good at displaying like printing matters. By micro-encapsulating the dispersion medium, a realization of the thin and flexible display device become possible. Further, an EPD (MC-EPD) using a microencapsulated suspension is a forceful candidate for realizing digital paper in the future. In this paper, principle and characteristics of the EPD are explained and application to rewritable sheet (MC-EPS) is introduced. MC-EPS is a rewritable sheet-like display formed by coating a flexible base material such as a polymer film or paper with microcapsules and applying an electric field from external. As an electrostatic latent image formation technique in the electro photography field can be applied as a voltage impression method, the development of the special writing equipment is unnecessary.

    2017-01-01

    This volume presents the lecture notes from the authors’ three summer courses offered during the program “Automorphisms of Free Groups: Geometry, Topology, and Dynamics” held at the Centre de Recerca Matemàtica (CRM) in Bellaterra, Spain. The first two chapters present the basic tools needed, from formal language theory (regular and context-free languages, automata, rewriting systems, transducers, etc) and emphasize their connections to group theory, mostly relating to free and virtually-free groups. The material covered is sufficient to present full proofs of many of the existing interesting characterizations of virtually-free groups. In turn, the last chapter comprehensively describes Bonahon’s construction of Thurston’s compactification of Teichmüller space in terms of geodesic currents on surfaces. It also includes several intriguing extensions of the notion of geodesic current to various other, more general settings.

  19. W-infinity ward identities and correlation functions in the c = 1 matrix model

    International Nuclear Information System (INIS)

    Das, S.R.; Dhar, A.; Mandal, G.; Wadia, S.R.

    1992-01-01

    In this paper, the authors explore consequences of W-infinity symmetry in the fermionic field theory of the c = 1 matrix model. The authors derive exact Ward identities relating correlation functions of the bilocal operator. These identities can be expressed as equations satisfied by the effective action of a three-dimensional theory and contain non-perturbative information about the model. The authors use thee identities to calculate the two-point function of the bilocal operator in the double scaling limit. The authors extract the operator whose two-point correlator has a single pole at an (imaginary) integer value of the energy. The authors then rewrite the W-infinity charges in terms of operators in the matrix model and use this to derive constraints satisfied by the partition function of the matrix model with a general time dependent potential

  20. Human errors, countermeasures for their prevention and evaluation

    The accidents originated in human errors have occurred as ever in recent large accidents such as the TMI accident and the Chernobyl accident. The proportion of the accidents originated in human errors is unexpectedly high, therefore, the reliability and safety of hardware are improved hereafter, but the improvement of human reliability cannot be expected. Human errors arise by the difference between the function required for men and the function actually accomplished by men, and the results exert some adverse effect to systems. Human errors are classified into design error, manufacture error, operation error, maintenance error, checkup error and general handling error. In terms of behavior, human errors are classified into forget to do, fail to do, do that must not be done, mistake in order and do at improper time. The factors in human error occurrence are circumstantial factor, personal factor and stress factor. As the method of analyzing and evaluating human errors, system engineering method such as probabilistic risk assessment is used. The technique for human error rate prediction, the method for human cognitive reliability, confusion matrix and SLIM-MAUD are also used. (K.I.)

    2012-01-01

    We introduce constructive and classical systems for nonstandard arithmetic and show how variants of the functional interpretations due to Gödel and Shoenfield can be used to rewrite proofs performed in these systems into standard ones. These functional interpretations show in particular that our

  12. Critical mid-term uncertainties in long-term decarbonisation pathways

    International Nuclear Information System (INIS)

    Usher, Will; Strachan, Neil

    2012-01-01

    Over the next decade, large energy investments are required in the UK to meet growing energy service demands and legally binding emission targets under a pioneering policy agenda. These are necessary despite deep mid-term (2025–2030) uncertainties over which national policy makers have little control. We investigate the effect of two critical mid-term uncertainties on optimal near-term investment decisions using a two-stage stochastic energy system model. The results show that where future fossil fuel prices are uncertain: (i) the near term hedging strategy to 2030 differs from any one deterministic fuel price scenario and is structurally dissimilar to a simple ‘average’ of the deterministic scenarios, and (ii) multiple recourse strategies from 2030 are perturbed by path dependencies caused by hedging investments. Evaluating the uncertainty under a decarbonisation agenda shows that fossil fuel price uncertainty is very expensive at around £20 billion. The addition of novel mitigation options reduces the value of fossil fuel price uncertainty to £11 billion. Uncertain biomass import availability shows a much lower value of uncertainty at £300 million. This paper reveals the complex relationship between the flexibility of the energy system and mitigating the costs of uncertainty due to the path-dependencies caused by the long-life times of both infrastructures and generation technologies. - Highlights: ► Critical mid-term uncertainties affect near-term investments in UK energy system. ► Deterministic scenarios give conflicting near-term actions. ► Stochastic scenarios give one near-term hedging strategy. ► Technologies exhibit path dependency or flexibility. ► Fossil fuel price uncertainty is very expensive, biomass availability uncertainty is not.

    CERN Document Server

    Morris, Dennis

    2015-01-01

    This book is about spinors. The whole mathematical theory of spinors is within Clifford algebra, and so this book is about Clifford algebra. Spinor theory is really the theory of empty space, and so this book is about empty space. The whole of Clifford algebra is rewritten in a much simpler form, and so the whole of spinor theory is rewritten in a much simpler form. Not only does this book make Clifford algebra simple and obvious, but it lifts the fog and mirrors from this area of mathematics to make it clear and obvious. In doing so, the true nature of spinors is revealed to the reader, and, with that, the true nature of empty space. To understand this book you will need an elementary knowledge of linear algebra (matrices) an elementary knowledge of finite groups and an elementary knowledge of the complex numbers. From no more than that, you will gain a very deep understanding of Clifford algebra, spinors, and empty space. The book is well written with all the mathematical steps laid before the reader in a w...

    Directory of Open Access Journals (Sweden)

    Gal, Nissim

    2011-02-01

    Full Text Available Is landscape painting still relevant today? To answer this question the article examines the work of the contemporary artist Yehudit Sasportas. Sasporas offers a unique kind of written-drawn landscape painting that moves between the manual and the mechanical. The theoretical perspectives from which it is approached are taken, among others, from Plato, Heidegger and Derrida on the issue of writing. Sasportas painting, which may be characterized as "painting under erasure" or "Landscape Painting", serves as a key to understanding the status of painting as a relevant medium, not because it defines medium according to the modernist Greenbergian formula, but because it enables an understanding of painting as a field that exists in a variety of media. Painting as a field, in Sasportas's art, works and lives within various techniques and materials, even when it includes within itself a melancholic mark indicating doubt about its own relevance.

    2018-06-01

    We analyzed the adverse events associated with an off-label use of arterial stents and CE-marked iliac vein stents for the treatment of iliac venous thromboembolism and investigated their relationships with the anatomical features of the iliac vein, to gain insights into the development of a better iliac vein stent. Reports of adverse events following the use of stents in the iliac vein were retrieved from the Manufacturer and User Facility Device Experience (MAUDE) database that contain suspected device-associated complications reported to the Food and Drug Administration. Data from 2006 to 2016 were investigated. The literature analysis was also conducted using PubMed, Cochrane Library, EMBASE, and Web of Science focusing on English articles published up to 4 October 2016. The analysis of 88 adverse events from the MAUDE database and 182 articles from the literature revealed that a higher number of adverse events had been reported following the use of arterial stents in the iliac vein compared to CE-marked iliac vein stents. While stent migration and shortening were reported only for the arterial stents, stent fracture and compression occurred regardless of the stent type, even though a vein does not pulsate. A study of the anatomical features of the iliac vein implies that bending, compression, and kink loads are applied to the iliac vein stents in vivo. For designing, developing, and pre-clinical testing of stents intended for use in the iliac vein, the above mechanical load environments induced by the anatomical features should be considered.

  9. Surface and snowdrift sublimation at Princess Elisabeth station, East Antarctica

    2012-08-01

    Full Text Available In the near-coastal regions of Antarctica, a significant fraction of the snow precipitating onto the surface is removed again through sublimation – either directly from the surface or from drifting snow particles. Meteorological observations from an Automatic Weather Station (AWS near the Belgian research station Princess Elisabeth in Dronning Maud Land, East-Antarctica, are used to study surface and snowdrift sublimation and to assess their impacts on both the surface mass balance and the surface energy balance during 2009 and 2010. Comparison to three other AWSs in Dronning Maud Land with 11 to 13 yr of observations shows that sublimation has a significant influence on the surface mass balance at katabatic locations by removing 10–23% of their total precipitation, but at the same time reveals anomalously low surface and snowdrift sublimation rates at Princess Elisabeth (17 mm w.e. yr−1 compared to 42 mm w.e. yr−1 at Svea Cross and 52 mm w.e. yr−1 at Wasa/Aboa. This anomaly is attributed to local topography, which shields the station from strong katabatic influence, and, therefore, on the one hand allows for a strong surface inversion to persist throughout most of the year and on the other hand causes a lower probability of occurrence of intermediately strong winds. This wind speed class turns out to contribute most to the total snowdrift sublimation mass flux, given its ability to lift a high number of particles while still allowing for considerable undersaturation.

  10. Methodological issues in using sequential representations in the teaching of writing

    Directory of Open Access Journals (Sweden)

    Chien-Ching Lee

    2007-12-01

    Full Text Available This study looks at a specific application of Ainsworth's conceptual framework for learning with multiple representations in the context of using multiple sequential graphic organizers that are student-generated for a process-writing task. Process writing refers to writing that consists of multiple drafts. It may be a process of re-writing without feedback or re-writing based on feedback where the teacher or peers will provide feedback on the original draft and then the students will revise their writing based on the feedback given. The objective was to explore how knowledge of students' cognitive processes when using multiple organizers can inform the teaching of writing. The literature review analyzes the interaction of the design, function and task components of the framework; culminating in instructional approaches for using multiple organizers for classes with students of different writing abilities. Extended implications for designers of concept mapping tools based on these approaches are provided.

    2014-06-01

    Full Text Available The present article intends to represent a process of rereading, rewriting, reusing and reflecting about certain contemporary novel and historiography authors. In common, these novelists and historians have a way of writing that emphasizes the act of writing itself (or their own act of writing and, therefore, put their narrators in another discourse position when considering both the realist aesthetic and the historiographycal rhetoric. By textual procedures that describe and simulate acts of drafting, erasing, rewriting, revising, rebuting, and reopening, the authors in question put themselves into the text, questioning and reformulating not only the so called formal realism from the 18th century but also the historical research and its empirical method linked to the 19th century – both schools that survived and thrived for the last hundred years. In writing this article – reading, analyzing and rereading these authors – we could reflect on how academic texts are written.

    2006-07-01

    Toshiba has developed Non-rewritable (NRW) Field Programmable Gate Array (FPGA)-based safety-related Instrumentation and Control (I and C) system [1]. Considering application to safety-related systems, nonvolatile and non-rewritable FPGA which is impossible to be changed after once manufactured has been adopted in Toshiba FPGA-based system. FPGA is a device which consists only of defined digital circuit: hardware, which performs defined processing. FPGA-based system solves issues existing both in the conventional systems operated by analog circuits (analog-based system) and the systems operated by central processing unit (CPU-based system). The advantages of applying FPGA are to keep the long-life supply of products, improving testability (verification), and to reduce the drift which may occur in analog-based system. The system which Toshiba developed this time is Power Range Monitor (PRM). Toshiba is planning to expand application of FPGA-based technology by adopting this development method to the other safety-related systems from now on. (authors)

  13. Jude the Obscure de Thomas Hardy et l’autorité de la lettre Jude the Obscure by Thomas Hardy and the Power of the Letter

    Directory of Open Access Journals (Sweden)

    Stéphanie Bernard

    2009-10-01

    Full Text Available Thomas Hardy is usually considered a Victorian writer. Nonetheless, his last novel Jude the Obscure, announced the era of modernity which started with the twentieth century, just before he abandoned fiction to concentrate on poetry. With modernity looming in the background, Jude the Obscure allowed for the rewriting of tragedy. Urban settings have replaced the countryside and all signs of transcendence have vanished from society. This defeat of the divine is nevertheless accompanied by a great number of biblical references. Thomas Hardy quotes and uses the Divine Letter as if to rewrite it rather than to appear faithful to the Word. The text keeps offering itself to the spell of voice: it does so when Job utters words of revolt and then worship, when Jude lets his imagination flow from his lips so that he seems to live on in the text after he is dead, or when the voice of the novelist becomes the voice of a poet.

  14. Spatial Decomposition of Translational Water–Water Correlation Entropy in Binding Pockets

    Science.gov (United States)

    2015-01-01

    A number of computational tools available today compute the thermodynamic properties of water at surfaces and in binding pockets by using inhomogeneous solvation theory (IST) to analyze explicit-solvent simulations. Such methods enable qualitative spatial mappings of both energy and entropy around a solute of interest and can also be applied quantitatively. However, the entropy estimates of existing methods have, to date, been almost entirely limited to the first-order terms in the IST’s entropy expansion. These first-order terms account for localization and orientation of water molecules in the field of the solute but not for the modification of water–water correlations by the solute. Here, we present an extension of the Grid Inhomogeneous Solvation Theory (GIST) approach which accounts for water–water translational correlations. The method involves rewriting the two-point density of water in terms of a conditional density and utilizes the efficient nearest-neighbor entropy estimation approach. Spatial maps of this second order term, for water in and around the synthetic host cucurbit[7]uril and in the binding pocket of the enzyme Factor Xa, reveal mainly negative contributions, indicating solute-induced water–water correlations relative to bulk water; particularly strong signals are obtained for sites at the entrances of cavities or pockets. This second-order term thus enters with the same, negative, sign as the first order translational and orientational terms. Numerical and convergence properties of the methodology are examined.

  15. The uranium industry: long-term planning for short-term competition

    International Nuclear Information System (INIS)

    Vottero, X.; Georges Capus, G.

    2001-01-01

    Long term planning for short term competition Today, uranium producers face new challenges in terms of both production (new regulatory, environmental and social constraints) and market conditions (new sources of uranium supply, very low prices and tough competition). In such a context, long-term planning is not just a prerequisite to survive in the nuclear fuel cycle industry. In fact, it also contributes to sustaining nuclear electricity generation facing fierce competition from other energy sources in increasingly deregulated markets. Firstly, the risk of investing in new mining projects in western countries is growing because, on the one hand, of very erratic market conditions and, on the other hand, of increasingly lengthy, complex and unpredictable regulatory conditions. Secondly, the supply of other sources of uranium (uranium derived from nuclear weapons, uranium produced in CIS countries, ...) involve other risks, mainly related to politics and commercial restrictions. Consequently, competitive uranium supply requires not only technical competence but also financial strength and good marketing capabilities in order to anticipate long-term market trends, in terms of both demand and supply. It also requires taking into account new parameters such as politics, environment, regulations, etc. Today, a supplier dedicated to the sustainable production of nuclear electricity must manage a broad range of long-term risks inherent to the procurement of uranium. Taking into account all these parameters in a context of short-term, fast-changing market is a great challenge for the future generation. World Uranium Civilian Supply and Demand. (authors)

  6. What are the differences between long-term, short-term, and working memory?

    Science.gov (United States)

    Cowan, Nelson

    2008-01-01

    In the recent literature there has been considerable confusion about the three types of memory: long-term, short-term, and working memory. This chapter strives to reduce that confusion and makes up-to-date assessments of these types of memory. Long- and short-term memory could differ in two fundamental ways, with only short-term memory demonstrating (1) temporal decay and (2) chunk capacity limits. Both properties of short-term memory are still controversial but the current literature is rather encouraging regarding the existence of both decay and capacity limits. Working memory has been conceived and defined in three different, slightly discrepant ways: as short-term memory applied to cognitive tasks, as a multi-component system that holds and manipulates information in short-term memory, and as the use of attention to manage short-term memory. Regardless of the definition, there are some measures of memory in the short term that seem routine and do not correlate well with cognitive aptitudes and other measures (those usually identified with the term "working memory") that seem more attention demanding and do correlate well with these aptitudes. The evidence is evaluated and placed within a theoretical framework depicted in Fig. 1.

  7. Short term and medium term power distribution load forecasting by neural networks

    International Nuclear Information System (INIS)

    Yalcinoz, T.; Eminoglu, U.

    2005-01-01

    Load forecasting is an important subject for power distribution systems and has been studied from different points of view. In general, load forecasts should be performed over a broad spectrum of time intervals, which could be classified into short term, medium term and long term forecasts. Several research groups have proposed various techniques for either short term load forecasting or medium term load forecasting or long term load forecasting. This paper presents a neural network (NN) model for short term peak load forecasting, short term total load forecasting and medium term monthly load forecasting in power distribution systems. The NN is used to learn the relationships among past, current and future temperatures and loads. The neural network was trained to recognize the peak load of the day, total load of the day and monthly electricity consumption. The suitability of the proposed approach is illustrated through an application to real load shapes from the Turkish Electricity Distribution Corporation (TEDAS) in Nigde. The data represents the daily and monthly electricity consumption in Nigde, Turkey

  8. On R4 threshold corrections in type IIB string theory and (p,q)-string instantons

    International Nuclear Information System (INIS)

    Kiritsis, E.; Pioline, B.

    1997-01-01

    We obtain the exact non-perturbative thresholds of R 4 terms in type IIB string theory compactified to eight and seven dimensions. These thresholds are given by the perturbative tree-level and one-loop results together with the contribution of the D-instantons and of the (p,q)-string instantons. The invariance under U-duality is made manifest by rewriting the sum as a non-holomorphic-invariant modular function of the corresponding discrete U-duality group. In the eight-dimensional case, the threshold is the sum of an order-1 Eisenstein series for SL(2,Z) and an order-3/2 Eisenstein series for SL(3,Z). The seven-dimensional result is given by the order-3/2 Eisenstein series for SL(5,Z). We also conjecture formulae for the non-perturbative thresholds in lower-dimensional compactifications and discuss the relation with M-theory. (orig.)

  9. Computing element evolution towards Exascale and its impact on legacy simulation codes

    International Nuclear Information System (INIS)

    Colin de Verdiere, Guillaume J.L.

    2015-01-01

    In the light of the current race towards the Exascale, this article highlights the main features of the forthcoming computing elements that will be at the core of next generations of supercomputers. The market analysis, underlying this work, shows that computers are facing a major evolution in terms of architecture. As a consequence, it is important to understand the impacts of those evolutions on legacy codes or programming methods. The problems of dissipated power and memory access are discussed and will lead to a vision of what should be an exascale system. To survive, programming languages had to respond to the hardware evolutions either by evolving or with the creation of new ones. From the previous elements, we elaborate why vectorization, multithreading, data locality awareness and hybrid programming will be the key to reach the exascale, implying that it is time to start rewriting codes.

    Full Text Available This paper presents experimental results of a usability evaluation of a controlled language (CL authoring assistant designed to help non-professional writers create machine translatable source texts. As the author drafts the text, the system detects CL rule violations and proscribed terms. It also incorporates several support functions to facilitate rephrasing of the source. In order to assess the usability of the system, we conducted a rewriting experiment, in which we compared two groups of participants, one with the aid of the system and the other without it. The results revealed that our system helped reduce the number of CL violations by about 9% and the time to correct violations by more than 30%. The CL-applied source text resulted in higher fluency and adequacy of MT outputs. Questionnaire and interview results also implied the improved satisfaction with the task completion of those participants who used the system.

  12. From twistor string theory to recursion relations

    International Nuclear Information System (INIS)

    Spradlin, Marcus; Volovich, Anastasia

    2009-01-01

    Witten's twistor string theory gives rise to an enigmatic formula 1 known as the 'connected prescription' for tree-level Yang-Mills scattering amplitudes. We derive a link representation for the connected prescription by Fourier transforming it to mixed coordinates in terms of both twistor and dual twistor variables. We show that it can be related to other representations of amplitudes by applying the global residue theorem to deform the contour of integration. For six and seven particles we demonstrate explicitly that certain contour deformations rewrite the connected prescription as the Britto-Cachazo-Feng-Witten representation, thereby establishing a concrete link between Witten's twistor string theory and the dual formulation for the S matrix of the N=4 SYM recently proposed by Arkani-Hamed et al. Other choices of integration contour also give rise to 'intermediate prescriptions'. We expect a similar though more intricate structure for more general amplitudes.

  7. Managing in the Virtual World: How Second Life is Rewriting the Rules of "Real Life" Business

    Science.gov (United States)

    Wyld, David C.

    In this paper, we will explore the growth of virtual worlds - one of the most exciting and fast-growing concepts in the Web 2.0 era. We will see that while there has been significant growth across all demographic groups, online gaming in MMOGs (Massively Multiplayer Online Games) are finding particular appeal in today's youth - the so-called "digital native" generation. We then overview the today's virtual world marketplace, both in the youth and adult-oriented markets. Second Life is emerging as the most important virtual world today, due to the intense interest amongst both large organizations and individual entrepreneurs to conduct real business in the virtual environment. Due to its prominence today and its forecasted growth over the next decade, we take a look at the unscripted world of Second Life, examining the corporate presence in-world, as well as the economic, technical, legal, ethical and security issues involved for companies doing business in the virtual world. In conclusion, we present an analysis of where we stand in terms of virtual world development today and a projection of where we will be heading in the near future. Finally, we present advice to management practitioners and academicians on how to learn about virtual worlds and explore the world of opportunities in them.

  15. Boson-fermion duality in four dimensions: Comments on the paper by Luther and Schotte

    International Nuclear Information System (INIS)

    Garbaczewsky, P.

    1985-01-01

    Fock space for the fermion field can be identified with this for the boson field, provided the overall numbers of internal degrees of freedom are the same. As a consequence the respective free field Hamiltonian systems are equivalent (dual): the four component neutrino model is thus equivalent to the doublet of independent ('electric' and 'magnetic' respectively) Maxwell fields which are quantized in the manifest Coulomb gauge. This statement arises on the continuum field theory level and seems to falsify the claim that realistic photons can be constructed from (bound) pairs of neutrinos. The more correct claim in this framework is that each (anti)neutrino degree of freedom represents and is represented by the photon type ('electric' and 'magnetic' respectively) degree of freedom. By repeating the classic Weinberg's construction we can rewrite the common for both models Hamiltonian in two equivalent ways: in terms of a relativistic spin 1/2, m=0 field or in terms of the spin 1, m=0 doublet of four-potentials. One of them is the standard Maxwell ('electric') potential while the other has all symmetry properties of the dual ('magnetic') one. (orig.)

  16. Very-long-term and short-term chromatic adaptation: are their influences cumulative?

    Science.gov (United States)

    Belmore, Suzanne C; Shevell, Steven K

    2011-02-09

    Very-long-term (VLT) chromatic adaptation results from exposure to an altered chromatic environment for days or weeks. Color shifts from VLT adaptation are observed hours or days after leaving the altered environment. Short-term chromatic adaptation, on the other hand, results from exposure for a few minutes or less, with color shifts measured within seconds or a few minutes after the adapting light is extinguished; recovery to the pre-adapted state is complete in less than an hour. Here, both types of adaptation were combined. All adaptation was to reddish-appearing long-wavelength light. Shifts in unique yellow were measured following adaptation. Previous studies demonstrate shifts in unique yellow due to VLT chromatic adaptation, but shifts from short-term chromatic adaptation to comparable adapting light can be far greater than from VLT adaptation. The question considered here is whether the color shifts from VLT adaptation are cumulative with large shifts from short-term adaptation or, alternatively, does simultaneous short-term adaptation eliminate color shifts caused by VLT adaptation. The results show the color shifts from VLT and short-term adaptation together are cumulative, which indicates that both short-term and very-long-term chromatic adaptation affect color perception during natural viewing.

  17. Creation of an iOS and Android Mobile Application for Inferior Vena Cava (IVC) Filters: A Powerful Tool to Optimize Care of Patients with IVC Filters.

    Deso, Steven E; Idakoji, Ibrahim A; Muelly, Michael C; Kuo, William T

    2016-06-01

    Owing to a myriad of inferior vena cava (IVC) filter types and their potential complications, rapid and correct identification may be challenging when encountered on routine imaging. The authors aimed to develop an interactive mobile application that allows recognition of all IVC filters and related complications, to optimize the care of patients with indwelling IVC filters. The FDA Premarket Notification Database was queried from 1980 to 2014 to identify all IVC filter types in the United States. An electronic search was then performed on MEDLINE and the FDA MAUDE database to identify all reported complications associated with each device. High-resolution photos were taken of each filter type and corresponding computed tomographic and fluoroscopic images were obtained from an institutional review board-approved IVC filter registry. A wireframe and storyboard were created, and software was developed using HTML5/CSS compliant code. The software was deployed using PhoneGap (Adobe, San Jose, CA), and the prototype was tested and refined. Twenty-three IVC filter types were identified for inclusion. Safety data from FDA MAUDE and 72 relevant peer-reviewed studies were acquired, and complication rates for each filter type were highlighted in the application. Digital photos, fluoroscopic images, and CT DICOM files were seamlessly incorporated. All data were succinctly organized electronically, and the software was successfully deployed into Android (Google, Mountain View, CA) and iOS (Apple, Cupertino, CA) platforms. A powerful electronic mobile application was successfully created to allow rapid identification of all IVC filter types and related complications. This application may be used to optimize the care of patients with IVC filters.

  18. Short-term memory and long-term memory are still different.

    Science.gov (United States)

    Norris, Dennis

    2017-09-01

    A commonly expressed view is that short-term memory (STM) is nothing more than activated long-term memory. If true, this would overturn a central tenet of cognitive psychology-the idea that there are functionally and neurobiologically distinct short- and long-term stores. Here I present an updated case for a separation between short- and long-term stores, focusing on the computational demands placed on any STM system. STM must support memory for previously unencountered information, the storage of multiple tokens of the same type, and variable binding. None of these can be achieved simply by activating long-term memory. For example, even a simple sequence of digits such as "1, 3, 1" where there are 2 tokens of the digit "1" cannot be stored in the correct order simply by activating the representations of the digits "1" and "3" in LTM. I also review recent neuroimaging data that has been presented as evidence that STM is activated LTM and show that these data are exactly what one would expect to see based on a conventional 2-store view.

  6. Thermorewritable card by using dyes; Senryo wo mochiita kakikae kanona card

    Energy Technology Data Exchange (ETDEWEB)

    Muto, Y.

    1998-06-01

    Described herein are thermorewritable cards which use dyes. Rewritable cards, mainly used for membership and point cards, are themselves used repeatedly and required to be rewritable repeatedly for information they carry. The dyes and developers used for the conventional heat- and pressure-sensitive papers are colorless, leuco-dye precursors and acidic compounds with a phenolic hydroxyl group or the like. They transfer electrons to each other, opening the lactone ring of the dye precursor to develop the color. Developing and erasing the color are reversible chemical reactions, where the color is developed under heat and maintained by quenching. For erasing the color, it is heated and then slowly cooled to separate the precursor and developer phases from each other. A printer (thermal head) is required for developing and erasing a color. Durability under various conditions is another requirement of the card; it must be adaptable to weather conditions and resistant to sweat. The new thermorewritable card is protected from various adverse effects on its chemical reactions, and made as durable as the conventional cards. 3 refs., 5 figs., 1 tab.

    We use a variation of the Rietveld refinement method to calculate the amorphous content of composites formed by a silica xerogel amorphous matrix and iron particles embedded into. In order to apply the Rietveld refinement to amorphous structures an initial crystalline model is assumed with the same composition as the material to be modelled. In this work we try to refine the structure of compounds using the program MAUD. It is shown how this program can be used to determine the amorphous and crystalline fractions in composites consisting of an amorphous matrix and incorporated iron oxide particles. The analysed compounds underwent different thermal treatments. (Author)

    Predictions of long-term glass dissolution rates are highly dependent on the form of the affinity term in the rate expression. Analysis of the quantitative effect of saturation state on glass dissolution rate for CSG glass (a simple analog of SRL-165 glass), shows that a simple (1-Q/K) affinity term does not match experimental results. Our data at 100 degree C show that the data is better fit by an affinity term having the form (1 - (Q/K) 1 /σ) where σ = 10

    Exposure to a spatial location leads to habituation of exploration such that, in a novelty preference test, rodents subsequently prefer exploring a novel location to the familiar location. According to Wagner's (1981) theory of memory, short-term and long-term habituation are caused by separate and sometimes opponent processes. In the present study, this dual-process account of memory was tested. Mice received a series of exposure training trials to a location before receiving a novelty preference test. The novelty preference was greater when tested after a short, rather than a long, interval. In contrast, the novelty preference was weaker when exposure training trials were separated by a short, rather than a long interval. Furthermore, it was found that long-term habituation was determined by the independent effects of the amount of exposure training and the number of exposure training trials when factors such as the intertrial interval and the cumulative intertrial interval were controlled. A final experiment demonstrated that a long-term reduction of exploration could be caused by a negative priming effect due to associations formed during exploration. These results provide evidence against a single-process account of habituation and suggest that spatial habituation is determined by both short-term, recency-based memory and long-term, incrementally strengthened memory.

  11. Fokker-Planck equation of the reduced Wigner function associated to an Ohmic quantum Langevin dynamics

    Colmenares, Pedro J.

    2018-05-01

    This article has to do with the derivation and solution of the Fokker-Planck equation associated to the momentum-integrated Wigner function of a particle subjected to a harmonic external field in contact with an ohmic thermal bath of quantum harmonic oscillators. The strategy employed is a simplified version of the phenomenological approach of Schramm, Jung, and Grabert of interpreting the operators as c numbers to derive the quantum master equation arising from a twofold transformation of the Wigner function of the entire phase space. The statistical properties of the random noise comes from the integral functional theory of Grabert, Schramm, and Ingold. By means of a single Wigner transformation, a simpler equation than that mentioned before is found. The Wigner function reproduces the known results of the classical limit. This allowed us to rewrite the underdamped classical Langevin equation as a first-order stochastic differential equation with time-dependent drift and diffusion terms.

  12. The Jones polynomial as a new invariant of topological fluid dynamics

    Ricca, Renzo L; Liu, Xin

    2014-01-01

    A new method based on the use of the Jones polynomial, a well-known topological invariant of knot theory, is introduced to tackle and quantify topological aspects of structural complexity of vortex tangles in ideal fluids. By re-writing the Jones polynomial in terms of helicity, the resulting polynomial becomes then function of knot topology and vortex circulation, providing thus a new invariant of topological fluid dynamics. Explicit computations of the Jones polynomial for some standard configurations, including the Whitehead link and the Borromean rings (whose linking numbers are zero), are presented for illustration. In the case of a homogeneous, isotropic tangle of vortex filaments with same circulation, the new Jones polynomial reduces to some simple algebraic expression, that can be easily computed by numerical methods. This shows that this technique may offer a new setting and a powerful tool to detect and compute topological complexity and to investigate relations with energy, by tackling fundamental aspects of turbulence research.

  13. Mathematical methods for elastic plates

    Constanda, Christian

    2014-01-01

    Mathematical models of deformation of elastic plates are used by applied mathematicians and engineers in connection with a wide range of practical applications, from microchip production to the construction of skyscrapers and aircraft. This book employs two important analytic techniques to solve the fundamental boundary value problems for the theory of plates with transverse shear deformation, which offers a more complete picture of the physical process of bending than Kirchhoff’s classical one.   The first method transfers the ellipticity of the governing system to the boundary, leading to singular integral equations on the contour of the domain. These equations, established on the basis of the properties of suitable layer potentials, are then solved in spaces of smooth (Hölder continuous and Hölder continuously differentiable) functions.   The second technique rewrites the differential system in terms of complex variables and fully integrates it, expressing the solution as a combination of complex ana...

  14. Medium-induced gluon radiation and colour decoherence beyond the soft approximation

    2015-01-01

    We derive the in-medium gluon radiation spectrum off a quark within the path integral formalism at finite energies, including all next-to-eikonal corrections in the propagators of quarks and gluons. Results are computed for finite formation times, including interference with vacuum amplitudes. Rewriting the medium averages in a convenient manner we present the spectrum in terms of dipole cross sections and a colour decoherence parameter with the same physical origin as that found in previous studies of the antenna radiation. This factorisation allows us to present a simple physical picture of the medium-induced radiation for any value of the formation time, of interest for a probabilistic implementation of the modified parton shower. Interestingly -- and unexpectedly -- we also find a modification of the contribution from the hard vertex which cannot be factorized, at finite formation time, as the vacuum Altarelli-Parisi splitting function. Known results are recovered for the particular cases of soft radiatio...

    expressive language of pre-term children. to compare the expressive vocabulary of two year-old children born prematurely, to that of those born at term. the study sample was composed by 118 speech-language assessment protocols, divided in two groups: the pre-term group (PTG) composed by 58 underweight premature children followed by a multi-professional team at the Casa do Prematuro (House of Premature Children) at Unifesp, and the full-term group (FTG) composed by 60 full-term born children. In order to evaluate the expressive language of these children, the Lave - Lista de Avaliação do Vocabulário Expressivo (Assessment List of the Expressive Vocabulary) was used. The Lave is an adaptation of the LDS - Language Development Survey - for the Brazilian Portuguese Language. The Lave investigates the expressive language and detects delays in oral language. children born underweight and prematurely present a greater occurrence of expressive language delay, 27.6%. These pre-term children present significantly lower expressive vocabulary and phrasal extension than children of the same age born at full-term in all semantic categories. Family income proved to be positively associated to phrasal extension, as well as to gestational age and weight at birth; thus indicating the effect of these adverse conditions still during the third year of age. The audiological status was associated to word utterances in the PTG. children born prematurely and underweight are at risk in terms of vocabulary development; this determines the need for speech-therapy intervention programs.

    Stigma is used as a synonym for designation of individuals or group with some characteristic differ from other population. This means that any disease by itself can carry stigma. But the greatest stigmatization is still associated with mental illness. Stigmatization means rewriting the negative characteristics of individual or group and creation of social distance and neglect.

    Ferroelectric vortex in multiferroic materials has been considered as a promising alternative to current memory cells for the merit of high storage density. However, the formation of regular natural ferroelectric vortex is difficult, restricting the achievement of vortex memory device. Here, we demonstrated the creation of ferroelectric vortex-antivortex pairs in BiFeO3 thin films by using local electric field. The evolution of the polar vortex structure is studied by piezoresponse force microscopy at nanoscale. The results reveal that the patterns and stability of vortex structures are sensitive to the poling position. Consecutive writing and erasing processes cause no influence on the original domain configuration. The Z4 proper coloring vortex-antivortex network is then analyzed by graph theory, which verifies the rationality of artificial vortex-antivortex pairs. This study paves a foundation for artificial regulation of vortex, which provides a possible pathway for the design and realization of non-volatile vortex memory devices and logical devices.

    2016-10-01

    Full Text Available The Salem Witchcraft Trials (1692 have received a lot of attention from history and literature, although there are very few critical analysis of how this historical event has entered the literary field. Many works of historical fiction – considered the most suitable literary genre to talk about an historical event - have used it in their storylines; however, popular genres such as romance, crime fiction, fantasy and science fiction have also shown an interest in this witch hunt. The main reason for this interest can be found in the lack of final conclusions as regards what really happened in Salem. The main objective of this paper is to show how what happened in Salem has entered contemporary popular fiction with the aim of showing the interest that it still arises and to vindicate the production of more critical works about the literary construction of one of the events that most dramatically has affected the configuration of the American mind.

The new curriculum is at the same time intended to be a revision of the 1995 national curriculum supposedly in use now. For the purpose a team of three members was appointed by the Secondary School Teacher Development Project (nationally known as Proyek PGSM, comprising English teaching professionalls from Universitas Negeri Malang, GAJAHMADA UNIVERSITY, and a senior high school teacher of English. Following a study of the existing documents related to ELT in Indonesia, an initial draft was written and gradually developed following a series of discussions and exchanges of ideas with teachers and profesionalls in the field of ELT. By the 3 rd year of the appointment of the team, the draft for the new KURNAS comprising Books I, II, and III, has been completed and ready for a try-out. The try-out was intended to put into practise the Intensive Course (IC Program as one of the most important components of the new KURNAS for the development of fluency in English as an essential basis for the preparation of competent high school teachers of English. This article describes the background and the underlying principles of the curriculum revision, along with the classification and identification of courses, descriptions of courses their and syllabus outlines.
