  1. Kafka, paranoic doubles and the brain: hypnagogic vs. hyper-reflexive models of disrupted self in neuropsychiatric disorders and anomalous conscious states

    Kafka's writings are frequently interpreted as representing the historical period of modernism in which he was writing. Little attention has been paid, however, to the possibility that his writings may reflect neural mechanisms in the processing of self during hypnagogic (i.e., between waking and sleep) states. Kafka suffered from dream-like, hypnagogic hallucinations during a sleep-deprived state while writing. This paper discusses reasons (phenomenological and neurobiological) why the self projects an imaginary double (autoscopy) in its spontaneous hallucinations and how Kafka's writings help to elucidate the underlying cognitive and neural mechanisms. I further discuss how the proposed mechanisms may be relevant to understanding paranoid delusions in schizophrenia. Literature documents and records cognitive and neural processes of self with an intimacy that may be otherwise unavailable to neuroscience. To elucidate this approach, I contrast it with the apparently popularizing view that the symptoms of schizophrenia result from what has been called an operative (i.e., pre-reflective) hyper-reflexivity. The latter approach claims that pre-reflective self-awareness (diminished in schizophrenia) pervades all conscious experience (however, in a manner that remains unverifiable for both phenomenological and experimental methods). This contribution argues the opposite: the "self" informs our hypnagogic imagery precisely to the extent that we are not self-aware. PMID:20727134

  5. Franz Kafka.

    Roubicek, J

    1975-01-01

    The hereditary and environmental influences on the genius of Kafka's personality are discussed. His exterior, somatic constitution is represented by photos taken during his lifetime as well as some posthumous, imaginary portraits and sculptures by various, mostly Prague, artists. The concept of the artist's psychic formation - his mental makeup - is documented from his diary, dreams, letters, literary work and reports by his friends. The whole proves his introversion, ambivalence, hypersensitivity, obstinancy, anxieties, behavioral anomalies, a life rich in fantasies and his underestimation of his own literary work. (He speaks about it as an idiosyncrasy, wishing it to be burned after his death.) Some little-known drawings by Kafka complement the picture of his talents and creativity. The psychological and psychopathological roots of his extraordinary position in the cultural awareness of his epoch are discussed.

  6. Kafka's Stereoscopes

    DEFF Research Database (Denmark)

    Holm, Isak Winkel

    In 1911, in the provincial town of Friedland, Franz Kafka encountered the Kaiserpanorama: a stereoscopic peep show offering an illusion of three-dimensional depth. After the experience, he began to create literary passages that emulate the binocular set-up of the stereoscope in the juxtaposition...... of two images of the same object seen from slightly different perspectives. Kafka’s stereoscopes, as I suggest calling these passages, are crucial to an understanding of the relation between literature and the political in his work. The book sets out to map the political function of the stereoscopic...... style by proposing three theses concerning the content, form and function of the literary stereoscopes. At the level of content, Kafka’s stereoscopes offer a representation of the configuration of a specific community. At the level of form, his stereoscopes are structured as the juxtaposition of two...

  7. [Franz Kafka's anorexia nervosa].

    Fichter, M M

    1988-07-01

    The evidence for the hypothesis that the poet Franz Kafka had suffered from an atypical anorexia nervosa is presented. Kafka was slim and underweight throughout his life and showed an ascetic attitude and abjuration of physical enjoyment and pleasure (fasting, vegetarianism, sexual abstinence, emphasis on physical fitness). The analysis is mainly based on Kafka's own descriptions in his letters, diaries, and literary work. Kafka was achievement oriented, reported many sadomasochistic fantasies, and had an anancastic (obsessive-compulsive) depressive personality. In addition there is evidence for a disturbed psychosexual and gender identity development. Our results concerning Kafka's psychopathology do not question his genius as a poet.

  14. Kafka and Autism : The Undisclosed Logic Behind Kafka's Work.

    Science.gov (United States)

    Stuger, Jerry

    2017-08-01

    In this paper the hypothesis is presented that Franz Kafka was a person with autism. This is done by analyzing and discussing his biography, letters, diaries and major works. Kafka's autism is an integral diagnosis which encompasses both his personal life and his work. This interpretation is contrary to other interpretations from the past which in all cases were only partially applicable to explain Kafka's life and work. In Kafka research the big secret of Kafka was how he was able to write he did, like no one before him had done. The function and use of parables are also discussed to support this autism hypothesis concerning Franz Kafka which ultimately makes his life and work more understandable and accessible.

    On June 3, 2004, 80 years have passed since the death of one of the greatest and the most important world writers of 20th century, the Prague German writer Franz Kafka. On November 5, 2004 we reminded that remarkable anniversary, which was also the 3rd anniversary of revelation of the monument of Franz Kafka in Tatranské Matliare, the High Tatras. Franz Kafka suffered from lung tuberculosis from 1917 until his death 1924. He was treated on lung tuberculosis in the sanatorium "Villa Tatra" from December 20, 1920 until August 27, 1921 in Tatranské Matliare, the High Tatras. Lung tuberculosis was a very dangerous disease in that time and the treatment by dietotherapy, climatotherapy and symptomatic therapy without antituberculotic drugs was less effective in many patients. In the paper the disease of Franz Kafka was described according to available literature.

    The Breakdown of the Apparatus: With Franz Kafka ‘In the Penal Colony’ The article proposes a meticulous reading of ‘In the Penal Colony’ (1914), aiming to show how this story, in ways so far unnoticed by Kafka scholarship, represents something decisively new in his work. ‘In the Penal Colony......’ (1914) introduces a new social motif, afterwards recurrent in Kafka: a cruel, old legal and social formation breaking up, leaving an empty gap and opening to a new situation that could be even worse. My initial reading is expanded by placing the story in personal, literary and historical contexts. From...... a point of departure in Kafka’s diaries in 1914 a mapping is suggested of some important instances of specific intertextuality – Octave Mirbeau, Fyodor Dostoevsky and the Passion of the New Testament. Further, the story’s conception of society is – through Oswald Spengler – read into concrete historical...

  19. Franz Kafka's The Trial: guilty or innocent?

    Science.gov (United States)

    Siegel, E

    1996-07-01

    Through an examination of The Trial by Kafka I attempt to show that the depiction of the Court apparatus is dynamically related to the commission of unconscious crimes of the type we encounter in our patients. To provide a context for the novel, I discuss Kafka's biography and some possible unconscious motivations. My goal is to show how the concept of a particular type of superego pressure can be used to understand the subtle irony in The Trial. Although Joseph K.'s behavior frequently involves oedipal crimes, there are many preoedipal themes that help account for his experience of the Court. I contrast this psychoanalytic understanding of K.'s guilt with that of literary critics who interpret The Trial as an allegory of guilt but who minimize the psychological dimensions.

    Full Text Available In this paper, I discuss the poetic impact of the change of the grammatical gender of the words within literary texts. Indeed, the differences between languages make the translation of the gender and of its ambivalence very hard to transpose. Expressed by words designating clothes and machines, the discursive articulations of the sex and of the gender, closely linked to the cultural conditions of its construction, can be observed in the narratives of Nicolai Gogol, Franz Kafka and Stanisław Lem.

    COMENTARIO AL LIBRO " EL MUNDO PSICOLÓGICO DE KAFKA" POR EL ACADÉMICO ADOLFO DE FRANCISCO ZEA.

     

    Fui invitado en forma comedida, por el doctor Adolfo De Francisco, para comentar su obra: "El Mundo Psicológico de Kafka". Respondí que no era literato y menos crítico de Kafka. Sin embargo, acepté
    hacerlo siendo consciente de las limitaciones que me acompañan y para las que pido de todos ustedes su consideración. Tenía sí el deseo al reto de lo incógnito.
    Además sus argumentos fueron contundentes, pues se referían al compromiso con la Academia y, sin decírmelo, era también con él en nuestra historia compartida. Mis motivaciones y expectativas personales conscientes eran múltiples para sumergirme en sus ideas que mueven el espíritu desde la piel a lo trascendente, de lo interno a lo externo y viceversa, y en que cada palabra puede ser objeto de análisis profundo, pues esa es su esencia. Por ejemplo cuando el doctor De Francisco se refiere a la sublimación y a la estética, a la política, a la religiosidad, a la burguesía, al campesinado, a la nobleza, al absolutismo, al arte o a la historia, a la cosmovisión sociológica y literaria, al psicoanálisis para afrontar la realidad interna y externa, entonces el autor penetra en el mundo de la fantasía y del psiquismo, para entender el simbolismo implícito de Kafka.
    Las motivaciones personales inconscientes, pertenecen a las tendencias irracionales de hundirme en espacios complejos para luego intentar'ordenarlos; en medio está
    la contratransferencia que me une con el autor Adolfo De Francisco y otra la que se refiere a la temática kafkiana...

    Full Text Available Resumo O artigo tem por objeto o Direito e a Literatura. Mais precisamente, objetiva vislumbrar a possibilidade de uma intersecção entre os campos cognitivos do Direito e da Literatura, para compreender a dignidade humana à luz da obra artístico-literária A metamorfose, de Franz Kafka. Assim, em primeiro lugar, o texto centrou-se na possibilidade do diálogo entre as dimensões do Direito e da Arte, essencialmente a Literatura. Como toda grande obra de arte, o livro analisado contém em seu seio uma semente de ruptura e de proposta de movimento criador. Permite aos seus leitores uma abertura de consciência ao novo, a vislumbrar mundos diversos, a pensar transformações dos espaços socioculturais. Assim, no segundo momento, a partir da ideia de que as grandes obras de arte permitem uma análise da sociedade concreta e imanente, o texto centrou-se na investigação da trama literária. Por fim, a partir da história narrada por Kafka e das críticas dos valores da sociedade presentes no texto, principalmente a anulação do sujeito – transformado em animal – partiu-se para a possibilidade de se pensar uma mudança, visando à dignidade humana no mundo contemporâneo, marcado pelo totalitarismo. Palavras-chave: Direito, Literatura, Dignidade Humana, Kafka, Metamorfose Abstract The article focuses on the Law and Literature. More precisely, it aims to glimpse the possibility of an intersection between the cognitive fields of law and literature, in order to understand human dignity in light of the artistic and literary work The Metamorphosis by Franz Kafka. Thus, first, the text centered on the possibility of dialogue between the dimensions of the law of the literature. Like any great work of art, the book analyzed contains in its bosom a seed burst and proposing creative movement.

    Max Weber’s and Franz Kafka’s respective understandings of bureaucracy are as different as night and day. Yet, Kafka’s novel The Castle is best read with Max Weber at hand. In fact, Kafka relates systematically to all the dimensions in Weber’s ideal type of bureaucracy and give us a much......’s painting: Ascending and Descending. Nevertheless, Weber and Kafka can both be right. While Kafka looks at the bureaucratic phenomenon through persons who are marginalized, Weber’s perspective is historic-comparative and top-down. Are the observations of the one more correct than the other? The question...... is meaningless. As two opposite poles, Weber and Kafka ‘magnetize’ each other....

    Full Text Available In 1983 Giulio Einaudi asked Primo Levi to translate Kafka’s Trial for the new series «Scrittori tradotti da scrittori». The proposal sounded original and provocative, and Levi accepted eagerly. The translation, however, had a negative effect on him. While working on The Trial, Levi relived his Auschwitz season, revived his deepest fears, and fell back into depression: he felt as if he was himself on trial. This was partially due to a clash of literary styles as well as to two contrasting – and yet at times kindred – conceptions of language and communication. The present study addresses the following questions: were Levi and Kafka’s literary styles as opposed as Levi implies? How is Levi’s “obscure part” connected to Kafka? Why did Levi associate The Trial with his Holocaust experience and identify himself with Josef K.? What does Levi’s encounter with Kafka tell us about the shame of being human and our capacity to give an account of ourselves? By investigating Levi’s uncanny encounter with Kafka, my essay will discuss Levi’s theory of language, showing how the Levi-Kafka intersection opens up new ways of interpreting Levi’s concerns about communication, the work of the witness, moral responsibility, and shame, which coalesced into the reflections of The Drowned and the Saved.Nel 1983 Giulio Einaudi chiese a Primo Levi di tradurre Il processo di Kafka per la nuova serie Scrittori tradotti da scrittori.

Mentre lavorava al Processo, Levi rivisse la stagione di Auschwitz, risentì le sue più profonde paure e ricadde in depressione. Si sentiva come se fosse lui stesso processato.

  18. Natural and anthropogenic rare earth elements in Lago de Paranoá, Brasilia, Brazil

    Rare earth elements (REE) belong to the group of particle reactive elements and occur at ultratrace levels in natural waters. They are exclusively trivalent, but Ce and Eu can also be tetravalent and divalent, respectively, depending on the redox-level, the pH and the temperature of the fluid. Due to these redox changes, normalized REE patterns may show Ce and/or Eu anomalies. Recently, these high-tech metals raised significant public attention, as they are of great economic importance and consumption and hence release into the environment increased sharply. The most prominent example of a REE contamination is anthropogenic Gd, which is derived from Gd-based contrast agents used in magnetic resonance imaging. Due to their high stabilities, these compounds are not readily removed by commonly applied waste water treatment technologies and, therefore, are released from treatment plants into surface and ground waters. Hence, this anthropogenic Gd can be used as a tracer for the presence of waste water-derived substances such as pharmaceuticals and personal care products in river, lake, ground and tap waters. Lago de Paranoá is an artificial reservoir lake in the city of Brasilia, Brazil, and is currently considered a potential freshwater resource. The city's two waste water treatment plants are located on its shore and their effluents are discharged into the lake. To investigate the level of contamination, we took water samples at 11 stations in the lake and compared the REE concentrations in unfiltered and filtered (<200 nm) lake water. The unfiltered water samples show light REE enrichment (LaSN/YbSN: 1.37-1.98) and high REE concentrations (Sum REE: 192 - 476 ng/L), while the unfiltered water samples are heavy REE enriched (LaSN/YbSN: 0.15-0.61) at lower concentrations (Sum REE: 50 - 85 ng/L). This is due to the fact that light REE are preferentially bound to particle surfaces, while the heavy REE are preferentially complexed with ligands in solution. In marked

  2. Sediments in urban river basins: identification of sediment sources within the Lago Paranoá catchment, Brasilia DF, Brazil - using the fingerprint approach.

    2014-01-01

    The development of effective sediment management strategies is a key requirement in tropical areas with fast urban development, like Brasilia DF, Brazil, because of the limited resources available. Accurate identification and management of sediment sources areas, however, is hampered by the dearth of reliable information on the primary sources of sediment. Few studies have attempted to quantify the source of sediment within fast urbanizing, mixed used, tropical catchments. In this study, statistically verified composite fingerprints and a multivariate mixing model have been used to identify the main land use specific sources of sediment deposited in the artificial Lago Paranoá, Central Brazil. Because of the variability of urban land use types within the Lago Paranoá sub-catchments, the fingerprinting approach was additionally undertaking for the Riacho Fundo sub-catchment. The main contributions from individual source types (i.e. surface materials from residential areas, constructions sites, road deposited sediment, cultivated areas, pasture, farm tracks, woodland and natural gullies) varied between the whole catchment and the Riacho Fundo sub-catchment, reflecting the different proportions of land uses. The sediments deposited in the silting zones of the Lago Paranoá originate largely from urban sources (85 ± 4%). Areas with (semi-) natural vegetation and natural gullies contribute 10 ± 2% of the sediment yield. Agricultural sites have only a minor sediment contribution of about 5 ± 4% within the whole catchment. Within the Riacho Fundo sub-catchment there is a significant contribution from urban (53 ± 4%) source, such as residential areas with semi-detached housings (42 ± 3%) with unpaved roads (12 ± 3%) and construction sites (20 ± 3%) and agricultural areas (31 ± 2%). The relative contribution from land use specific sources to the sediment deposition in the silting zone of the Lago Paranoá demonstrated that most of the sediment is derived from

    Ogden, Thomas H

    2009-04-01

    The ways in which Franz Kafka and Jorge Luis Borges struggled with the creation of consciousness in their lives and in their literary works are explored in this two-part essay. In Part I, the author juxtaposes a biographical sketch of Kafka with a close reading of his story "A Hunger Artist" (1924), in which a character (whose personality holds much in common with that of Kafka) spends his life in a quasi-delusional state starving himself in public performances. The hunger artist's self-awareness (of having lived a life devoid of the experience of love and mutual recognition) is achieved in the context of an interpersonal experience in which he has, in fact, found/created "the food [he] liked," that is, an experience of loving and being loved, of seeing and being seen, of being aware of and alive to his own imminent death. This fragile, paradoxical state of consciousness is sustained for only a moment before it is attacked, but not entirely destroyed.

    Full Text Available Attempts at the literary classification of Kafka's texts often prove to be problematic. Most authors are at a loss, so they propose more than classification. The problem of the literary classification of Kafka's texts is treated only in a few German literary encyclopedias and in interpretations and analyses of his texts. In the interpretations and literary analyses Kafka is mostly classified as a Modernist, but some authors see him as a Postmodernist. Most German literary historians and encyclopedia writers are caught in a dilemma about this subject and so propose more than one literary classification: Kafka is assigned to Expressionism and also proclaimed as a representative of the Existentialism, Surrealism or Magic realism. However most German literary historians often assign Kafka to the Expressionism on historical grounds.

    In many cases in large urban centers, which have appropriate waterbodies, small-scale fisheries are the only source of cheap protein for the poor. In Lago Paranoá, located in Brasília, the capital city of Brazil, fishing was studied by conducting interviews with 53 fishers filling in logbooks from March, 1999 to March, 2000 in three fishing communities. The fishers come from the poorest towns around Brasília, known as satellite-towns. They have been living there on average for 21.7 years (s = 9.6 years), their families have 4.9 members (s = 3.6) on average and 44.2% do not have a basic education. However, such characteristics are similar to the socioeconomic indices of the metropolis where they live. In spite of being illegal between 1966 and 2000, fishing generated an average monthly income of U 239.00 dollars (s = U 171.77 dollars). The Nile Tilapia Oreocrhromis niloticus is the main captured species (85% of a total number of landings in weight of 62.5 t.). Fishing is carried out in rowing boats, individually or in pairs. The fishing equipment used are gillnets and castnets. Gillnets were used actively, whereby the surface of the water is beaten with a stick to drive Tilapias towards nets as they have the ability to swim backwards. This fishing strategy was used in 64.7% of the fisheries, followed by castnets (31.1%) and by gillnets which were used less (4.2%). The fish is sold directly in the streets and fairs of the satellite-towns to middlemen or to bar owners. Three communities have different strategies in terms of fishing equipments, fishing spots and commercialization. Consequently, there are statistically significant differences in relation to the monthly income for each one of these communities.

  10. Mysterious Illnesses of Human Commodities in Woody Allen and Franz Kafka

    Directory of Open Access Journals (Sweden)

    Iris Bruce

    1998-01-01

    Full Text Available The article examines correspondences between Woody Allen's film Zelig and texts by Franz Kafka. Both Leonard Zelig and Gregor Samsa ( The Metamorphosis suffer from mysterious illnesses which are multi-determined. Twentieth-century racial stereotypes are partially responsible for them; other causes lie in the commercialization of life in early twentieth-century society. Zelig's illness parallels the cultural trends and political movements of his time and becomes full-blown in the fascist movement. Zelig is therefore also a commentary on the cultural climate which helped bring about the rise of fascism. Kafka could not benefit from Allen's hindsight, but Kafka's representation of what turns human beings into commodities with no identity of their own nonetheless complements Allen's picture. Further parallels are drawn between Zelig and Kafka's hunger artist, the performing ape Rotpeter ("A Report to an Academy", and Karl Rossmann ( Amerika . All of these protagonists fail to retain a sense of selfhood in a commodified world. Yet the causes for their illnesses lie not in themselves but in society on the whole, and for this reason there is no cure for these human commodities. Unlike Kafka, though, Woody Allen grants Zelig a cure in the end, a cure which is possible only in the realm of fantasy.

    Full Text Available Kafka non è stato un impiegato passivo e distratto. Recenti studi sui suoi documenti di lavoro hanno evidenziato una passione e una competenza professionale notevoli. Questa competenza è stata riversata nelle sue opere letterarie che parlano di lavoro e di organizzazioni con una conoscenza diretta. Lo stile simbolista di Kafka è stato molto efficace nel cambiare il modo di vedere le organizzazioni. Lo scrittore, in particolare, ha intuito la crescita degli ultimi anni della popolazione eccedente. Kafka ha saputo afferrare la psicologia e gli atteggiamenti profondi dei lavoratori che fronteggiano la loro superfluità e l’espulsione dal mondo del lavoro. Più in dettaglio, Kafka è stato capace di analizzare la resa psicologica alla superfluità che si esprime soprattutto con una specifica forma di “vuoto mentale”.

    2016-02-01

    Full Text Available Ao falar sobre Contemplação, o seu primeiro livro, Kafka diz haver nele uma “desordem sem salvação”, que “é preciso se aproximar muito” para ver aí “alguma coisa”. Esse artigo é resultado de uma tentativa de aproximação desse lugar ideal de contemplação a partir do qual não apenas podemos ver neste conto “alguma coisa”, mas a coisa que está em jogo em uma de suas últimas obras, o conto A construção. Em Contemplação, nos interessará o movimento dos personagens de dentro para fora e de fora para dentro e a fuga ao perigo de alienação que é representado por um outro com um poder aniquilador sempre articulados à busca da autonomia. “A coisa” que está em jogo em “A construção” e em Contemplação será a escrita na qual irão se cruzar, como estados inseparáveis, a autonomia e a alienação.

    2000-12-01

    What happens when we heed a call? Few writers have been as suspicious of their vocation as Franz Kafka (1883-1924). His story, A Country Doctor, (1919) ostensibly about a night visit to a patient that goes badly wrong, suggests a modern writer's journey to the heart of his work. There he discovers that trust, like the tradition which might sustain him, is blighted. This essay also examines Kafka's attitude to illness and the medical profession, and his close relationship with his uncle, Siegfried Löwy (1867-1942), a country doctor in Moravia.

  18. [From the preoedipal to the oedipal: Kafka as an example of the problems of transition from dyadic to triangular relationships].

    Science.gov (United States)

    Odağ, Celal

    2004-01-01

    In early childhood, the mother is the primary object of the child's dyadic relationship, and mother and child form a unity together. In the oedipal period, however, the father enters this dyadic unity, and it is with his entry that the dyad becomes triangular and begins to incorporate features of a triangular relationship. In some cases the father may even replace the mother, thereby reducing the mother's relevance. Kafka is an interesting example of this unusual case. In addition, a close look at Kafka's psychopathology facilitates a better understanding of the interdependency of preoedipal, oedipal and adolescent stages. A psychoanalytic approach to Kafka reveals severe disturbances of these major developmental steps, which, on their part, impede the development of Kafka's individual identity. It is against this background that Kafka's author identity will be analysed in greater detail, by regarding representations of separatedness, continuity, and originality in his literary work to be expressions of his author identity. One further assumption of this paper is that Kafka's ideal self and superego are not separate from each other. His feelings of guilt, shame and fear demonstrate that these instances are very much intertwined and not distinct from each other. The reader's emotional agony while reading some of Kafka's work signalizes that Kafka's ideal self and superego form a unity together. Psychoanalysts, however, commonly accept that, in normal development, ideal self and superego should become separate entities, and continue their activities separately. It seems as though Kafka's ideal self and superego have not gained sovereignty yet, and likewise, it is difficult to separate the son's superego or ideal self from his father's.

  19. Geochemical signature and properties of sediment sources and alluvial sediments within the Lago Paranoá catchment, Brasilia DF: a study on anthropogenic introduced chemical elements in an urban river basin.

    One of the largest urban agglomerations in Brazil is the capital Brasilia and its surrounding area. Due to fast urban sprawl and accelerated land use changes, available water supplies are near their limits. The water supply depends largely on surface water collected in reservoirs. There are increasing concerns regarding water shortages due to sediment aggradations, and of water quality due to geochemical modification of sediments from human activities. The concentration of 18 chemical elements and five sediment properties was analyzed from different potential land-based sediment sources and deposited alluvial sediment within the Lago Paranoà catchment. The goal of this study was to assess the distribution of chemical elements and geochemical/physical properties of potential sediment sources in the Lago Paranoá catchment. Principal component analysis and hierarchical cluster analysis were used to investigate the influence of different land use types on the geochemistry of sediments. Geochemical fingerprints of anthropogenic activities were developed based on the results of the cluster analysis grouping. The anthropogenic input of land use specific geochemical elements was examined and quantified by the calculation of enrichment factors using the local geological background as reference. Through comparison of the geochemical signature of potential sediment sources and alluvial sediments of the Lago Paranoá and sub-catchments, the relative contribution of land use specific sediment sources to the sediment deposition of the main water reservoir were estimated. The existing findings suggest a strong relationship between land use and quantifiable features of sediment geochemistry and indicate that urban land use had the greatest responsibility for recent silting in the Lago Paranoá. This assessment helps to characterize the role of human activities in mixed-used watersheds on sediment properties, and provides essential information to guide management responses

    The paper summarises the accessible literature on the life and work of well-known American lung surgeon, Professor Dr. Med. Robert Klopstock, who was in the years 1920-1924 a friend Franz Kafka. Professor Klopstock was of Hungarian origin and he got acquainted with Franz Kafka at the end of the year 1920 in Tatranské Matliare (The High Tatras). They were both patients treated for lung tuberculosis. They became close friends and their mutual correspondence shows their real friendship. Robert Klopstock was present at Franz Kafka's death-bed on June 3, 1924 in Kierling, near Klosterneuburg, not far from Vienna. Robert Klopstock studied at Medical Faculties of the Universities in Budapest, Prague, Kiel and Berlin. After his graduation in 1933 in Berlin, he worked as a lung surgeon at various surgical clinics and departments in Budapest and Berlin. In 1936 Robert Klopstock together with his wife visited the High Tatras and Tatranské Matliare. In 1937 Robert Klopstock with his wife Gizela, a writer and a translator, who translated the first chapters of Franz Kafka's novel "Trial" into Hungarian language, went to United States of America. During his stay in U.S.A. Dr. Med. Robert Klopstock was very active as a lung surgeon and a scientist. He published 64 specialized scientific papers, mostly in American medical journals. He became Professor of Lung Surgery at Downstate Medical Centre in New York-Brooklyn. He died on June 15, 1972 in New York.

    Full Text Available O objetivo do presente ensaio é apresentar um panorama geral da recepção brasileira de Kafka. O texto inicia-se com a justificativa sobre a pertinência da pesquisa e mostra como Kafka, no início de seu processo receptivo, ou seja, 1956, foi traduzido de maneira não sistemática para o português. O primeiro texto publicado no Brasil foi Die Verwandlung, cuja versão alemã data de 1915. Entretanto a narrativa não foi traduzida a partir do alemão, mas sim do inglês. Outros textos foram traduzidos a partir do francês. Traduções diretas do original alemão só vieram a lume a partir de 1983, entre elas: Kleine Fabel, Der Geier, Gibs auf! e Vor dem Gesetz É digno de nota que, já em 1941, publicaram-se ensaios e outras informações sobre Kafka e sua obra, portanto muito antes das traduções das obras propriamente ditas. Em agosto daquele mesmo ano, por exemplo, Otto Maria Carpeaux escreveu o primeiro artigo sobre o autor no jornal Correio da Manhã. A obra de Kafka é hoje tema de inúmeras pesquisas.

A palestra empreende a reintegração do escritor no panorama de vários contextos da modernidade no início do século XX, tais como: o movimento da reforma da vida, debates intelectuais, pesquisa acadêmica no campo de acidentes de trabalho, várias relações amorosas e o entusiasmo para novas invenções técnicas. Como resultado, o autor sustenta que se poderia imaginar Kafka perfeitamente na sociedade européia anterior à I Guessa, descrita por Thomas Mann no romance "A montanha mágica".

    Full Text Available Directed by Piotr Dumala, Franz Kafka is a very unusual example of a biographical movie. The film is composed of carefully thought-out poetic images which, according to the director himself, reflect the “psychic landscape” of the title character. Thus scenes inspired by Kafka's life and his Diaries intertwine with episodes that refer to his literary works. Dumala shows deep understand-ing of the writer’s characteristic way of depicting reality and the unusual perspective of narration indicates his thorough knowledge of Kafka’s works. Dumala draws on this heritage and creates an emotional portrait of the writer, while at the same time providing a universal reflection on the human condition.

Franz Kafka and Bruno Schulz – two classics of modernity, residents of “Republic of dreams”, if to use a beautiful metaphor of Schultz, were from Jewish families lived in a multicultural and multilingual Austro-Hungarian Empire absorbed with best achievements of the Austrian culture. As noted by J. Updike: «Kafka and Schulz – two unremarkable man, born in the backyard of once powerful empire, took a bite at the same apple myth, but from different sides». Both were able to transform the insightful observation in prophecy, describing the dreams and nightmares as precisely as if they were facts of life, both shed light on human nature and witnessed history, complementing each other. I. Klekh rightly observes certain «commonness» of their creative method, stressing the importance for the two writers’ motif of transformation, transformation, mutual penetration of books and worlds.

    Full Text Available Algunos escritos de Franz Kafka, cartas y diarios, tomados a manera de material clínico, sirven como pretexto para investigar acerca de las dificultades que siempre acompañan al sujeto en el acceso a su propio deseo. La palabra de Kafka en estos textos, es especialmente valiosa para tratar lo paradójico del deseo humano, y para ilustrar un aspecto importante que vemos en la clínica, aquel que consiste en mantener este deseo a distancia, en prolongar el momento del encuentro con él. Su correspondencia amorosa y la "Carta al padre", son un testimonio iluminador en el que está presente el terror que siempre tuvo Kafka a contraer matrimonio. Partiendo de esta carta, vemos cómo es abordada la cuestión de la elección de objeto amoroso, qué vínculos pueden establecer algunos sujetos con una mujer, y cómo la función paterna es determinante. Cómo la clave en la elección de objeto, estaría en relación a la posición del sujeto frente al límiteimpuesto por la ley del padre.

    Full Text Available A literatura de Kafka, produzida no alvorecer do século XX, é mais um processo em andamento na Europa fin-de-siècle. É a escrita de um jovem que busca, para além de seu trabalho burocrático, um sentido para estar ali. Sua produção literária é a tentativa de dar conta desse mundo que não permite uma apropriação, que ora o incorpora, ora o exclui, por sua condição judaica. Condição muitas vezes secundária para ele e os de sua geração, mas que não deixa de marcá-los significativamente. Marcas involuntárias, que não os abandonam e retornam conforme as produzem. Marcas que caracterizam e permitem a construção de uma obra e de uma vida. Aqui tenta-se ler os vestígios dessa tradição abandonada, mas que não se deixa apagar. Que retorna, que impulsiona a produção, não como uma Musa, mas sim como angústia e necessidade de produzir.Kafka's literature is one of the many intellectual projects underway in the European fin-de-siècle. It is the work of a young man in search of a meaning for being there, despite his bureaucratic work at a government agency. His literature is an attempt to get a hold of a society that sometimes accepts him and sometimes rejects him, for his Jewish background. A background usually not considered by him and his fellows, but always present in many different ways. It is this background that gives way to his literary production and, thus, his own life. This paper is an attempt to read the Jewish background that is behind Kafka's work, a background always present, which works in favor of his production, not as a Muse, but as anguish and the necessity to write.

    Kafka' s thoughts and writings might come from three cultural sources: Western culture, Jewish culture and Chinese culture. The relationship between Kafka and the latter two has been much studied before, but the relationship between Kafka and Western culture, especially ancient Greek culture, has been neglected. Kafka referred to Greek culture broadly and profoundly: borrowing, applying, deconstructing and even rewriting Greek myths. He took in the ideas of absurdity and labyrinth, and the image of Sisyphus, to deduce and develop them into images and structures of paradox and conundrum, as well as a series of characters like "K", who have a fate similar to that Sisyphus.%卡夫卡思想与创作的文化渊源应该包括三个方面:西方文化、犹太文化和中国文化,但以往我们对卡夫卡与后二者的关系的研究往往较多,反而忽略了卡夫卡与西方文化,尤其是与古希腊文化的关系的研究。卡夫卡广泛而深入地涉猎希腊文化,借用、利用、消解,甚至改写希腊神话。他从古希腊文化中吸纳了有关荒诞、迷宫的观念,以及西西弗斯的形象,然后演绎、发展成了他笔下的悖谬、谜语意象和结构,以及一系列的与西西弗斯同命运的"K们"形象。

    There have always been two forces in the world: one that is sharp as knife, and one that is tender as water. Kafka obviously belongs to the latter. His ever presentation of delicateness reflects his loneliness and timidity. However, when it turns to the nature of soft approach to power, such delicateness often gives immeasurable power, as we have observed in Kafka's literature world. His works, full of strangeness in novelty, show a profound charm in quietness, from which however one read will find a "mystery" and "unfathomed depth", such as in "Castle", "Metamorphosis", even in "Cave". Such are the reflection of Kafka's life, and the entanglement of his dream and reality. Today, when we cherish the memory of Kafka with great respect, we may feel that literature may be light as air, but it nourishes man constantly.%世界上向来有两种力量:一种是锋利如刀,一种是温柔似水。卡夫卡显然属于后者。他孤独胆怯处处表现出一种柔弱。不过这柔弱一旦变成一种"以柔克刚",又常常会让人有无法估量的感觉,而卡夫卡正是在文学的世界里让我们看到了他的力量。他的作品,在新奇中充满诡异,显示出一种深不见底的"幽魅",不论你如何解读,都能找到一种"神秘"而又"意犹未尽"。《城堡》是这样,《变形记》甚至包括《地洞》无不如此。它是卡夫卡生命的写真,又是他梦与现实的一种纠结。今天我们怀着无比崇敬的心情缅怀他,纪念他,或许从中能感觉到,文学就是这样,虽轻如空气,但却无时无刻不在给人以滋养。

    When Sigmund Freud was taken ill in 1923 with a malignant tumor of his right upper jaw he was initially treated by the famous Viennese rhino-laryngologist, Professor Markus Hajek. One year later, Franz Kafka, who was suffering from pulmonary tuberculosis which had spread to the larynx, was likewise placed under the care of this distinguished specialist. Neither of the encounters proved beneficial from the professional point of view and both well-known patients received remarkably poor attentions in keeping with the general autocratic attitude by clinical chiefs of the time in Vienna. Franz Kafka was terminally ill when he came to Hajek and no treatment was yet available for the disabling and painful laryngeal complication of his advanced tuberculosis. He died about a month after leaving Hajek's ward in Vienna. Sigmund Freud required repeated subsequent operations on his jaw and the insertion of a prothesis. Hajek had handed Freud over to Hans Pichler for further care and it was entirely due to the skill of this extremely competent and empathetic maxilliary surgeon that Freud lived for another 16 years, working to almost full capacity.

Freud, in this text, enquires into the origins of religion, morality, social institutions and law. He contends that this origin is to be found in a crime, the killing of the primal father by a band of brothers, followed by the institution of totemism and the incest prohibition. Freud's psychoanalytical account of the origins of the totem and the prohibition of incest has been challenged from various quarters. The article enquires whether Freud's Totem and Taboo and its theory of the primal horde in relation to the origins of law should be dismissed in light of these challenges, or whether some insight can still be gained from it. The second option is affirmed, with Derrida's 'Before the Law' pointing to the importance of reading Freud in a way analogous to Kafka's Before the Law, and more specifically to the need for a reconsideration of the originary nature of the Oedipus complex, so as to arrive eventually at a kind of 'pre-origin' of law.

Jedoch war der Prozess der Verbreitung von Kafkas Schaffen in Litauen, besonders in den 70er Jahren, unsystematisch, auch wurde der Prager Dichter unterschiedlich, widersprüchlich und tenden­ziell bewertet – mal wurde er als ein pessimistischer und somit der „sozialistischen“ Welt fremde Autor gesehen, mal als ein Kritiker der kapitalistischen Ge­sellschaft akzeptiert.

    In the current studies, we tested the prediction that learning of novel patterns of association would be enhanced in response to unrelated meaning threats. This prediction derives from the meaning-maintenance model, which hypothesizes that meaning-maintenance efforts may recruit patterns of association unrelated to the original meaning threat. Compared with participants in control conditions, participants exposed to either of two unrelated meaning threats (i.e., reading an absurd short story by Franz Kafka or arguing against one's own self-unity) demonstrated both a heightened motivation to perceive the presence of patterns within letter strings and enhanced learning of a novel pattern actually embedded within letter strings (artificial-grammar learning task). These results suggest that the cognitive mechanisms responsible for implicitly learning patterns are enhanced by the presence of a meaning threat.

    Using Kafka's short story A Country Doctor and clinical examples as vehicles, the author demonstrates the centrality of psychoanalysts' styles and life experiences to the psychoanalytic process. Albeit charged with a distinct facilitative task, psychoanalysts inevitably bring their qualities as "fellow sufferers" (to use D. M. Orange's term) into their sessions. They experience pressures placed upon them as the "subject presumed to know," as Lacan describes. They encounter the ubiquity of self-deception, facing many unknown and unpredictable elements as they surrealistically travel through time with their patients. While understandably wanting to take refuge from their vulnerability, psychoanalysts cannot escape the influence of their individualistic and idiosyncratic natures on the transformational encounters they facilitate.

    The dying emperor in Kafka's tale has sent you a message of great importance, entrusted to his strongest herald. But the throne room, the palace, the city are so huge and so crowded with people that the message can never reach you. Reverse the tale and you have the problem of Knowledge Transfer (KT)--brutally illustrated by the fate of New Orleans. Important information, of unquestioned validity, soundly based in research and easy to understand, simply does not get through to practice. A recent evaluation of the Ottawa Ankle Rules makes the point all too clearly. Indeed, the KT problem is worse than Kafka's. Economically motivated people and organizations actively distort the messages--and try to trip the herald--while grossly oversimplified frameworks of understanding include no language in which the messages can be expressed. "More research" is not the answer.

Nevertheless there are very few critics that have taken this sentence to the letter. As Josef K. is executed at last, it must be supposed that the character should have commited some sort of crime. Though it has been speculated a lot about which this crime could be, it has been impossible to reach a firm decision. What this way of reading the story shows is that is tremendously difficult to conceive the idea of a world in which it would be possible to arrest and execute innocent people with no justification at all. But this is precisely the basis of the fiction world imagined by Kafka, who through The Process prefigured the terror lived all over Europe dominated by totalitarism.

    Al comienzo de El proceso el narrador afirma que Josef K. fue arrestado una mañana «sin que hubiera hecho nada malo». Son muy pocos, sin embargo, los críticos que se han tomado esta frase al pie de la letra. Puesto que Josef K. es finalmente ejecutado, se supone más bien que el personaje habría cometido algún tipo de falta. Aunque se ha especulado mucho sobre cuál pudiera ser esa falta, no se ha podido llegar a una firme decisión al respecto. Lo que este modo de leer el relato revela es que resulta muy difícil concebir la idea de un mundo en el que fuera posible arrestar y ejecutar a personas inocentes, sin ninguna clase de justificación. Pero en esto consiste, precisamente, el mundo de ficción imaginado por Kafka, quien prefiguró así en El proceso el terror vivido en la Europa dominada por el totalitarismo.

    Full Text Available O uso de espaço e de alimento pela lontra Lontra longicaudis no Lago Paranoá de Brasília vêm sendo estudados desde 1997. Entre novembro de 2000 e outubro de 2002 foram realizadas visitas semanais a um transecto de 1700m às margens do lago para coleta de fezes e localização de pegadas e tocas. Foi confirmado que as lontras usam o lago permanentemente durante todo o ano para alimentação e repouso. Nos 24 meses foram coletadas 239 amostras de fezes de lontras e identificados doze diferentes itens alimentares. O item encontrado com mais freqüência foi a tilápia Oreochromis niloticus presente em 39,6% das amostras. A maioria das amostras foi encontrada em uma toca específica e nas suas imediações. Há evidências de que as lontras utilizam o lago principalmente para alimentação enquanto seus abrigos estão nos córregos tributários. O período de nascimento dos filhotes parece coincidir com o final da estação seca.

    Full Text Available This study aims to analyze how Haruki Murakami reads the real icons of Johnnie Walker and Colonel Sanders in Kafka on the Shore deconstructively. First, we will focus on the signification process of the icon, which are to a great extent molded by advertisements, and then on the deconstruction of their signifieds. For the purpose, we will apply Barthes’ idea of myth. We are also interested in revealing how Murakami constructs Johnnie Walker and Colonel Sanders to be characters in the novel. The analysis shows that the construction of the icons through advertisements leads to the creation of their mtyhs, and then Murakami reads them deconstructively to be opposite signifieds.

    Full Text Available En este ensayo se disertará sobre un problema que parece ser poco cuestionado en los trabajos precedentes que se han inspirado en la incomparable narrativa de Franz Kafka. Hablamos en particular de la “estética de lo adverso”, de la imposibilidad, del obstáculo, del fracaso; aspectos que se desvelan como un vector temático con desarrollo semántico y de constante aparición en la obra del escritor checo. Frente a tan intrincada semiosis, nuestra pretensión es responder parcialmente a algunas preguntas que buscan abrir espacios sígnicos que permitan hacer una lectura más amplia y, quizá, más edificante de la obra kafkiana, lo que necesariamente concluirá en el fracaso como una nueva alternativa hermenéutica, o una alternativa hermenéutica construida desde el fracaso. This essay deals with a problem that does not seem to be questioned in preceding works based on Franz Kafta’s incomparable narrative. We are specifically speaking of “the aesthetics of the adverse,” the impossibility, the obstacle, the failure; aspects that are revealed as a topic with semantic development and with permanent appearance in the work of this Czech writer. Before such a complicated semiosis, our intention is to partially respond to some questions intended to open sign spaces that allow having a wider and maybe more edifying reading of Kaffa’s work, which will necessarily result in the failure as a new hermeneutic alternative or a hermeneutic alternative built from failure.

  15. "Brücke dreht sich um!". A Deconstructionist Reading of Kafka's "Die Brücke"

    Directory of Open Access Journals (Sweden)

    Eva Hoffmann

    2014-12-01

    Full Text Available Franz Kafka's (1883-1924 "Die Brücke" is one of the less well-known texts by one of the most prolific authors of literary modernity. However, this short prose text embodies prevalent questions of literary modernity and philosophy as it reflects the crisis of language in regard of identity, communication, and literary production. Placed in the context of fin-de-siècle's discourse of language crisis, this article provides a dialogue between Kafka's "Die Brücke" and Hannah Arendt's (1906-1975 philosophy of thinking and speaking in The Life of the Mind. Contrary to Arendt's understanding of the metaphor as "a carrying over" between the mental activities of the solitude thinker and a reconciliation with the pluralistic world shared with others, this article argues for a deconstructionist reading of "Die Brücke" as a tool to reevaluate Arendt's notion of a shared human experience ensured through language and illustrates the advantages of poetic texts within philosophical discourses.

  16. Kafka, Borges, and the creation of consciousness, Part II: Borges--a life of letters encompassing everything and nothing.

    Science.gov (United States)

    Ogden, Thomas H

    2009-04-01

    The ways in which Kafka and Borges struggled with the creation of consciousness in their lives and in their literary works are explored in this two-part essay. In Part II, a biographical sketch of Jorge Luis Borges is juxtaposed with a close reading of one of his fictions, "The Library of Babel" (1941a). In this story, the universe is an infinite Library, a psychological/literary space comprised of books that contain everything that has ever been or ever will be written. By the end of the story, Borges becomes a character in his own fiction. This development was paralleled in Borges's "real life" as he invented a persona named "Borges," a literary creation that allowed Borges to become a character in a story that was his life. The essay concludes with a comparison of the ways in which Borges and Kafka each used writing as a way of creating his own distinctive form of consciousness, and, in so doing, contributed to the creation of twentieth-century consciousness.

  17. The Relationship Between Character and Destiny in Modernity Through the Siren's Myth: from Homer to Kafka and Joyce

    Directory of Open Access Journals (Sweden)

    Jacobo de Camps Mora

    2016-02-01

    Full Text Available The present article studies the relationship between Heraclitean concepts êthos and daímôn from Classical Antiquity to the first half of the 20th century by analysing the differences between the siren’s myth in The Odyssey and its contemporary readings in Kafka and Joyce. It starts by approaching the relationship Erich Auerbach establishes between both concepts in Homer and Greek Tragedy and opposing them to the modern birth of what Imre Kertész terms “functional man”. It then focuses on Kafka to show the modern lack of communication between character and destiny –the symbol of which is the siren’s silence in Das Schweigen der Sirenen–, as well as a possible answer to the set out nihilism. Regarding Joyce, it studies the chapter “Sirens” from Ulysses to reveal how the modern song’s universal attraction frustrates its listeners’ self-expression.

    Full Text Available Dopo il confronto con il famoso testo kafkiano Il Processo da parte di Alberto Spaini, Ervinio Pocar e Giorgio Zampa, nel 1983 esce nella collana ‘Scrittori tradotti da scrittori’ di Einaudi il Kafka di Primo Levi. È certamente una prova non semplice, sia perché lo scrivere di Kafka è uno scrivere oscuro ed enigmatico sia perché le pagine di Kafka obbligano per chi le traduce a misurarsi e a riflettere su temi quali la colpa, la vergogna e la dignità umana, temi che anche Levi, reduce da Auschwitz, fu costretto ad affrontare. Come sostiene Levi in un articolo pubblicato su «Il Tempo» sempre in quel 1983: «[R]ivisitare Kafka [è] una palinodia del mio ottimismo illuministico, ed un modo singolare di rivivere quella mia lontana stagione». Ma il lavoro sul testo kafkiano, tra avvicinamento e prese di distanza, si dipana anche come processo di riflessione sulla scrittura, in particolare su compiti e responsabilità dello scrivere e del comunicare, e sullo svisceramento di una lingua, il tedesco, che assume un ruolo in molti eventi decisivi della vicenda personale leviana.After Alberto Spaini, Ervino Pocar and Giorgio Zampa’s edition of Kafka’s famous novel The Trial, in 1983 Primo Levi’s translation of the same text was published by Einaudi in the series ‘Scrittori tradotti da scrittori’. The translation of Kafka’s works is certainly not an easy task. Indeed, on the one hand, Kafka’s writing is obscure and enigmatic; on the other hand, it forces the translator to deal with and reflect upon such themes as guilt, shame and human dignity, which Levi, as an Auschwitz survivor, had to tackle as well. In an article published by «Il Tempo» in the same year, Levi claimed that «[R]ivisitare Kafka» was «una palinodia del mio ottimismo illuministico, ed un modo singolare di rivedere quella mia lontana stagione».  Levi’s work on Kafka’s text, oscillating between proximity and distance, also entails a process of reflection

  19. The sanctuary of empathy and the invitation of engagement: psychic retreat, Kafka's "A Hunger Artist," and the psychoanalytic process.

    Science.gov (United States)

    Karbelnig, Alan Michael

    2014-12-01

    As part of a broader scholarly and political effort to unify clinical psychoanalysis, the author argues that psychoanalysts' presence, engagement, and framing constitute the three overarching features of their work. Additionally, patients' propensity to turn inward, alternatively known as psychic retreat or narcissistic withdrawal, provides a similarly unifying way to view psychoanalytic patients. Narrowing the investigation to a phenomenological one, the author tapers the exploration further by studying the psychoanalytic process as it unfolds in real time. After addressing the problems of diffusion in professional identity and psychoanalytic theory that have plagued psychoanalysis from the start, the author presents three case examples into which he integrates Kafka's short story "A Hunger Artist." These vehicles are utilized to demonstrate how such nomenclature provides the basis for a more cohesive understanding of how psychoanalysts work.

    Full Text Available A leitura interpretativa que o presente estudo faz de O Processo afasta-se das interpretações tradicionais. Os fundamentos metafísicos que deram origem aos gêneros e aos estilos de época são insuficientes para apreenderem a especificidade da obra literária. Eles são substituídos pela própria obra, entendida como processo. Ler poeticamente a obra é fazer eclodir a sua poética. Para tanto, assinalam-se na obra de Kafka três grandes processos: a vida cotidiana, a vida jurídico-institucional, o manifestação do real. A unidade desses três processos é realizada por um quarto: o processo narrativo. A culpa de Joseph K. é lida como a morte que irrompe com a vida, mas da qual o personagem não quer tomar-se consciente. Todo o processo narrativo, do qual resulta O Processo, consiste nesta descoberta abissal e inexorável.

Argüimos que, sendo talvez o mais esperançoso do escritor, o texto analisa de forma estética e em estado extremo o fantástico que envolve nossas relações com a técnica maquinística.  O registro histórico em que se inscreve o conto é transcendido por uma criação poética que deixa entrever de forma original e pioneira, mas não tecnológica, o que atualmente começa a ser chamado de pensamento pós-humanista. Palavras-chave Kafka, “Na Colônia penal”, técnica e cultura; tecnologia: crítica. Abstract Kafka offers us an astonishing reflection about the relationship between man and machine in his short story ‘In the penal colony’. We argue here that, perhaps being the most hopeful text written by the author, this piece analyses in an extreme and original way the fantastical that surrounds us in the midst of the machinistic technological universe. The historical register in which the text inserts itself is transcended by a poetical creation that allows us to see an original and pioneering, but not technical, point of view – what now begins to be called post-humanist thought.

    Full Text Available The author explores the central importance of death in Bakhtin’s carnival and notes that death is joyfully accepted as it gets rid of the old and makes space for the new. Death for Bakhtin is “life’s regeneration”. But in many societies both simple and sophisticated this is not the case. Here we deal with a sacrificial logic where death is feared and displaced onto a sacrificial victim who is killed for the benefit of the majority. Although we like to think of modern society as being beyond sacrifice we see it in many cultural formations. The author uses anthropology as an interpretive key to explain the story of Franz Kafka’s Metamorphosis. Indeed the Metamorphosis reads like a purificatory rite in which one member of the social group (a family becomes a monster (the insect, literally and is slowly but systematically rejected by the other members of his family. In the end, Gregor the insect/family member who has become a kind of filthy cockroach, dies to save his family from further disgust. His body is disposed of anonymously. At the end of the story we see Gregor’s sister has bloomed into adolescence and so (without doing too much damage to the text we can interpret the story as a kind of spring purification right to discard the bad and the rotten and bring in the good and the fertile.

  14. A Comparative Study on the Narrative Styles of Kafka and Ma Yuan%卡夫卡与马原叙事风格的比较研究

    Ma Yuan is a representative of Chinese Avant-garde writers and Kafka is a writer of Western expressionism.The former is good at using narrative traps,while the latter is skilled in absurd description. Kafka is the father of modernism,while Ma Yuan starts the Chinese Avant-garde literature.Although dif-ferent in the way of expression,the two,with absurd description,provide the reader with imagery of multi-ple symbolic connotations.Ma Yuan in his early period of creation unconsciously absorbs the Kafkaesque creative features and internalizes these characteristics.Meanwhile,Ma Yuan has his own distinctive quality in these aspects:the mixture of the illusory and the real,the switch between the reader,the author and the narrator,and mystical narration.%马原是中国先锋派的代表作家,卡夫卡是西方表现主义大家。马原善用叙述圈套,卡夫卡善用悖谬化描写。卡夫卡开创了现代派文学的先河,马原则开启了中国先锋文学。虽然两者的表达方式不同,但都通过荒诞化的描写,向世人展开了一幅毕加索式具有多重象征内涵的意象之画。马原在文学创作早期不自觉地吸收了卡夫卡式的创作特征,并将这些特征内化为自己的作品风格。同时,他在虚幻与真实交织,读者、作者及叙述者的互换,神秘主义的叙述化方面具有独到之处。

    Kafka was a keen interested in the art of fable during his lifetime,and his creation of fiction showed obviously some allegoricalized features.In order to make the art of fiction return to its original liv-ing poetic,Kafka constantly strengthened allegorical feature of his novels,and even there was a fable-like structure contained in the each fiction of his later creation.Kafka's fictions with the fable-like structure j ust directly presented itself,but didn't seem to point to any other specific"means",and had the aesthetic char-acteristics of extra-parable,so it can be regarded as a kind of artistic form with"nothingness".%卡夫卡生前一直钟情于寓言艺术,其小说创作呈现出明显的寓言化特征。为了让小说回归其本来所具有的生活诗性,卡夫卡小说创作的寓言化特征也在不断地得到深化,乃至于其后来的小说均蕴含着一个拟寓言结构。卡夫卡小说的拟寓言结构,除了赤裸地袒呈自身外,似乎根本不指向其他任何特定的“意味”,具有一种超寓言的审美功能,故而可以被看做是一种“无”意味的形式。

    The era Kafka lived in was the era of great machine invention and application. Kafka was very familiar with the ins and outs of machines, since his job in an insurance company was to deal with the performance of machines. Therefore, his attention is directed to the issues of machines in " In the Penal Colony", one of his famous short stories. The age of machines reverses the relationship between human beings and the machine. Consequently, humans are reduced to the victims rather than the beneficiaries of the age of machines. Through his depiction of the machines, Kafka shows the evils and diseases of modern society.%卡夫卡生活在一个机器大发明、大运用、大规模机械复制的时代。他对机器非常熟悉,在劳工工伤保险公司所从事的工作也与机器的安全性能密切相关。他对机器时代的关注与思考集中地体现在他的短篇小说《在流放地》中。机器时代首先将人与机器的关系颠倒过来,随后这种被颠倒的关系渗透到社会的各个领域,最终人更多地成为机器时代的受害者,而不是受益者。通过对机器的描写,卡夫卡敏锐地触摸到现代社会的弊端与疾病。

Distributed messaging system, which shares data on message basis,become the core technology gradually. With the extreme growing of information recently, the traditional system which focus on small account of data, cannot meet our demands for data processing. A high-throughput distributed messaging system with the function of real-time consumption become necessary. Kafka is such arequirement.

    From several evidence,it shows that Franz Kafka had read the Stran-ge Stories from a Chinese Studio in German version. Through comparative readi-ng in both composes from Pu Songling and Kafka,it could be found,Kafka's creative concept,alienation logic,the law of his different world,and other aspects are influenced and inspirited by Strange Stories from a Chinese Studio rom Pu Songling in varying degrees. It can be conclude, Pu Singling's influence on Kaf-ka and the contribution of surrealist literature are immense.%根据迄今为止各家的探轶结果可知,弗朗兹·卡夫卡曾阅读过德文版的《聊斋志异》。通过对蒲松龄与卡夫卡作品的对比阅读,可以发现,在卡夫卡的创作构思、异化逻辑、异世界法则等方面都不同程度地受到了蒲松龄《聊斋志异》的影响与启发。由此可以得见,蒲松龄对卡夫卡创作的影响以及对超现实主义文学的贡献巨大。

The two factors may be found in the identification between the two narrators and in the two most emphasized possibilities in the interpretation of the novel, or rather, subjectivity and national identity. Agualusa’s novel may also be defined as belonging to ‘minor literature’, as conceived by Deleuze and Guattari’s text Kafka: Toward a minor literature. According to these authors, in minor literature, each subject is inscribed in and connected with politics, a highly strong factor in The Book of Chameleons.O presente trabalho visa a apontar a presença do duplo e da duplicidade no romance O vendedor de passados, do escritor angolano José Eduardo Agualusa, que podem ser encontradas desde a identificação entre os dois narradores do texto até as duas mais insistentes possibilidades de leitura da obra: uma referente à subjetividade e, a outra, relativa à identidade nacional.

  5. Double supergeometry

    CERN Document Server

    Cederwall, Martin

    2016-01-01

    A geometry of superspace corresponding to double field theory is developed, with type II supergravity in D=10 as the main example. The formalism is based on an orthosymplectic extension OSp(d,d|2s) of the continuous T-duality group. Covariance under generalised super-diffeomorphisms is manifest. Ordinary superspace is obtained as a solution of the orthosymplectic section condition. A systematic study of curved superspace Bianchi identities is performed, and a relation to a double pure spinor superfield cohomology is established. A Ramond-Ramond superfield is constructed as an infinite-dimensional orthosymplectic spinor. Such objects in minimal orbits under the OSp supergroup ("pure spinors") define super-sections.

    Attempts to modify gravity in the infrared typically require a screening mechanism to ensure consistency with local tests of gravity. These screening mechanisms fit into three broad classes; we investigate theories which are capable of exhibiting more than one type of screening. Specifically, we focus on a simple model which exhibits both Vainshtein and kinetic screening. We point out that due to the two characteristic length scales in the problem, the type of screening that dominates depends on the mass of the sourcing object, allowing for different phenomenology at different scales. We consider embedding this double screening phenomenology in a broader cosmological scenario and show that the simplest examples that exhibit double screening are radiatively stable.

    Shakespeare's Hamlet has special appeal to Franz Kafka,and the two have a deep spiritual relationship.The paper tries to use the relevant records in Kafka's diaries,letters and literary works,especially the play The Warden of the Tomb,to analyze this relationship.The paper argues that,as the symbol of modern psyche,Prince Leo is a more modern version of Hamlet,and there exist complicated and deep conflicts between various moral attitudes in his cosmopolitan impulse.The ghosts in the play are the metaphorical representation of moral labyrinth in Kafka's literary world.Kafka's writings not only diagnose and anatomize the modern psyche,but also set modern individuals the difficult task to set right their psyche's ecology.%莎士比亚笔下的哈姆莱特形象吸引着卡夫卡,二者之间存在着深刻的精神联系。本文结合卡夫卡日记、书信中的相关记述,并通过对其剧本《墓园看守人》及相关作品的解读来探讨这一联系。本文认为,作为现代灵魂的象征,剧本中的利奥王子是哈姆莱特形象的进一步发展,也是卡夫卡的自传性形象,其兼容并包的世界主义冲动内部包含着复杂而深刻的伦理冲突,作品中的鬼魂形象则是卡夫卡的文学世界中道德迷宫的隐喻;卡夫卡的写作不仅对现代灵魂混乱的伦理生态做出了剖析,也向现代人提出了重整自我灵魂内部秩序的要求。

    Does knowledge of language consist of abstract principles, or is it fully embodied in the sensorimotor system? To address this question, we investigate the double identity of doubling (e.g., slaflaf, or generally, XX; where X stands for a phonological constituent). Across languages, doubling is known to elicit conflicting preferences at different levels of linguistic analysis (phonology vs. morphology). Here, we show that these preferences are active in the brains of individual speakers, and they are demonstrably distinct from sensorimotor pressures. We first demonstrate that doubling in novel English words elicits divergent percepts: Viewed as meaningless (phonological) forms, doubling is disliked (e.g., slaflaf linguistic preferences doubly dissociate from sensorimotor demands: A single stimulus can elicit diverse percepts, yet these percepts are invariant across stimulus modality--for speech and signs. These conclusions are in line with the possibility that some linguistic principles are abstract, and they apply broadly across language modality.

    In Kafka' s The Castle and other novels, the relationship between the serious character "K" and the funny assistants often constitutes a key narrative, which makes the novel full of distinct comedy. This description shows Kafka' s "God-like" observer status in his works, in which he let "K" to be tested in comic scenes. At the same time it can also be seen as of Kafka' s positive understanding of the world and life in enduring spirit. Responding to Kafka with this interpretation may he seen as a possible way of entering into his world.%在卡夫卡的《城堡》等小说中,严肃的主人公"K"与滑稽的助手们的关系常会构成叙事的关节,使小说充满鲜明的喜剧色彩。这种描写是卡夫卡"上帝般"旁观者身份的表现,使他让K在喜剧情景中接受考验,同时也可以看做是卡夫卡以坚韧的精神、喜剧的意识对世界和人生的积极理解。以这种解读来回应卡夫卡,兴许是进入卡夫卡世界的可能路径。

    This article analyses the influence of Austrian writer Kafka on Yu Hua who is one of the Chinese vanguard writers in the style of the two novels The Metamorphosis and The 1986. Not only on narrative style, but on the mode of plot, the processing of details and the thought of theme, Yu Hua echoes from afar with Kafka who is the originator of modernist sehool in the 20th century. Such influence en- abled Yu Hua to break through and innovate from the level of both the form and tile thought in his novels. Under the deep influence of Kafka, Yu Hua' s creation, has witnessed space for free expression and no longer gets bogged down in the bondage of reality.%摘要:本文从影响研究的角度,以《变形记》和《一九八六年》两部短篇小说为例,分析奥地利作家卡夫卡对中国先锋作家余华的影响。余华的《一九八六午》在叙事风格、情节模式、细节处理和主题思路方面,均与20世纪现代文学鼻祖卡夫卡遥相呼应。这种影响使余华的写作无论是在形式层面上还是在思想层面上,都有了相当的突破与创新;在卡夫卡的深刻影响下,余华的创作同时有了一个自由表述的空间,而不再拘泥于现实的束缚。

    We present the construction of unintegrated double parton distribution functions which include dependence on transverse momenta of partons. We extend the formulation which was used to obtain the single unintegrated parton distributions from the standard, integrated parton distribution functions. Starting from the homogeneous part of the evolution equations for the integrated double parton distributions, we construct the unintegrated double parton distributions as the convolutions of the integrated double distributions and the splitting functions, multiplied by the Sudakov form factors. We show that there exist three domains of external hard scales which require three distinct forms of the unintegrated double distributions. The additional transverse momentum dependence which arises through the Sudakov form factors leads to non-trivial correlations in the parton momenta. We also discuss the non-homogeneous contribution to the unintegrated double parton distributions, which arises due to the splitting of a singl...

    Double stars have been systematically observed since William Herschel initiated his program in 1779. In 1803 he reported that, to his surprise, many of the systems he had been observing for a quarter century were gravitationally bound binary stars. In 1830 the first binary orbital solution was obtained, leading eventually to the determination of stellar masses. Double star observations have been a prolific field, with observations and discoveries - often made by students and amateurs - routinely published in a number of specialized journals such as the Journal of Double Star Observations. All published double star observations from Herschel's to the present have been incorporated in the Washington Double Star Catalog. In addition to reviewing the history of visual double stars, we discuss four observational technologies and illustrate these with our own observational results from both California and Hawaii on telescopes ranging from small SCTs to the 2-meter Faulkes Telescope North on Haleakala. Two of these technologies are visual observations aimed primarily at published "hands-on" student science education, and CCD observations of both bright and very faint doubles. The other two are recent technologies that have launched a double star renaissance. These are lucky imaging and speckle interferometry, both of which can use electron-multiplying CCD cameras to allow short (30 ms or less) exposures that are read out at high speed with very low noise. Analysis of thousands of high speed exposures allows normal seeing limitations to be overcome so very close doubles can be accurately measured.

    We probe doubled geometry with dual fundamental branes. i.e. solitons. Restricting ourselves first to solitonic branes with more than two transverse directions we find that the doubled geometry requires an effective wrapping rule for the solitonic branes which is dual to the wrapping rule for fundam

  6. Topological Quantum Double

    Science.gov (United States)

    Bonneau, Philippe

    Following a preceding paper showing how the introduction of a t.v.s. topology on quantum groups led to a remarkable unification and rigidification of the different definitions, we adapt here, in the same way, the definition of quantum double. This topological double is dualizable and reflexive (even for infinite dimensional algebras). In a simple case we show, considering the double as the "zero class" of an extension theory, the uniqueness of the double structure as a quasi-Hopf algebra. A la suite d'un précédent article montrant comment l'introduction d'une topologie d'e.v.t. sur les groupes quantiques permet une unification et une rigidification remarquables des différentes définitions, on adapte ici de la même manière la définition du double quantique. Ce double topologique est alors dualisable et reflexif (même pour des algèbres de dimension infinie). Dans un cas simple on montre, en considérant le double comme la "classe zéro" d'une théorie d'extensions, l'unicité de cette structure comme algèbre quasi-Hopf.

    The ancient record, "During the first year of King Yi, the day dawned twice at Zheng", has provided important clues to early Chinese chronicles. The astronomical conditions and visible area distributions related to such a "double dawn" event are discussed, and the precision and current problems in the calculations of ancient astronomical phenomena are shown. On such a basis, all the solar eclipses from 1000 BC to 840 BC are calculated and their associated "double dawn" features investigated. The conclusion that the "double dawn" was a solar eclipse occurring on April 21st, 899 BC is corfirmed to be the most reasonable.

    Full Text Available (francuski Nous aimerions montrer que Le Terrier de Kafka est représentatif de l’étrange «intersubjectivité» telle qu’elle peut être pensée chez un auteur «mineur». La nouvelle tend à nous rappeler qu’être un sujet à part entière (susceptible d’intersubjectivité c’est tout d’abord occuper une place «majeure» dans la société. C’est à cette condition que peut être dépassé le moi animal, que peut être risquée la vie, pour se poser comme maître. Ceux qui occupent une place mineure en sont réduit à un Moi animal au sens hégélien, pour qui la vie est la suprême valeur. Ils n’ont pas la force de la risquer et ne peuvent donc entrer dans une lutte frontale pour l’affirmation de leur liberté et de leurs droits, dite de maîtrise. Leur espace de lutte n’est pas une scène publique, de bataille, une scène de la représentation pour filer la métaphore théâtrale, mais un boyau souterrain duquel, dans leur farouche isolement, ils entendent grouiller d’autres consciences prisonnières comme eux. Cellesci n’arrivent pas à accéder à la lumière de la reconnaissance publique, condition d’une existence pleinement accomplie chez Hegel, pour qui l’homme trouve son accomplissement en tant que citoyen de l’État. Ceux qui sont à la marge doivent inventer de nouvelles formes de luttes, souterraines, sous la figure du couloir retors, du réseau, de l’interaction, de branchement de masses entre elles.

    At least one neutrino has a mass of about 50 meV or larger. However, the absolute mass scale for the neutrino remains unknown. Furthermore, the critical question: Is the neutrino its own antiparticle? is unanswered. Studies of double beta decay offer hope for determining the absolute mass scale. In particular, zero-neutrino double beta decay (\\BBz) can address the issues of lepton number conservation, the particle-antiparticle nature of the neutrino, and its mass. A summary of the recent results in \\BBz, and the related technologies will be discussed in the context of the future \\BBz\\ program.

    A new stellarator configuration, the Double-Helix Stellarator (DHS), is introduced. This novel configuration features a double-helix center post as the only helical element of the stellarator coil system. The DHS configuration has many unique characteristics. One of them is the extreme low plasma aspect ratio, A {approx} 1--1.2. Other advantages include a high enclosed volume, appreciable rotational transform, and a possibility of extreme-high-{beta} MHD equilibria. Moreover, the DHS features improved transport characteristics caused by the absence of the magnetic field ripple on the outboard of the torus. Compactness, simplicity and modularity of the coil system add to the DHS advantages for fusion applications.

    2016-01-01

    Here we introduce reflection positive doubles, a general framework for reflection positivity, covering a wide variety of systems in statistical physics and quantum field theory. These systems may be bosonic, fermionic, or parafermionic in nature. Within the framework of reflection positive doubles, we give necessary and sufficient conditions for reflection positivity. We use a reflection-invariant cone to implement our construction. Our characterization allows for a direct interpretation in terms of coupling constants, making it easy to check in concrete situations. We illustrate our methods with numerous examples.

    2013-01-01

    Double-slits provide incoming photons with a choice. Those that survive the passage have chosen from two possible paths which interfere to distribute them in a wave-like manner. Such wave-particle duality continues to be challenged and investigated in a broad range of disciplines with electrons, neutrons, helium atoms, C60 fullerenes, Bose-Einstein condensates and biological molecules. All variants have hitherto involved material constituents. We present a matterless double-slit scenario in which photons generated from virtual electron-positron pair annihilation in head-on collisions of a probe laser field with two ultra-intense laser beams form a double-slit interference pattern. Such electromagnetic fields are predicted to induce material-like behaviour in the vacuum, supporting elastic scattering between photons. Our double-slit scenario presents on the one hand a realisable method to observe photon-photon scattering, and demonstrates on the other, the possibility of both controlling light with light and n...

    2013-11-27

    Motivated by the problem of identifying Majorana mode operators at junctions, we analyze a basic algebraic structure leading to a doubled spectrum. For general (nonlinear) interactions the emergent mode creation operator is highly nonlinear in the original effective mode operators, and therefore also in the underlying electron creation and destruction operators. This phenomenon could open up new possibilities for controlled dynamical manipulation of the modes. We briefly compare and contrast related issues in the Pfaffian quantum Hall state.

    2014-06-01

    Full Text Available The work concerns contact problems focused on biomechanical systems modelled by a multibody approach. The example is modelling of impact between a body and an infrastructure. The paper firstly presents algorithm for minimum distance calculation. An analytical approach using a tangential plain perpendicular to an initial one is applied. Contact force generated during impact is compared by three different continuous force models, namely the Hertz’s model, the spring-dashpot model and the non-linear damping model. In order to identify contact parameters of these particular models, the method of numerical optimization is used. Purpose of this method is to find the most corresponding results of numerical simulation to the original experiment. Numerical optimization principle is put upon a bouncing ball example for the purpose of evaluation of desirable contact force parameters. The contact modelling is applied to a double pendulum problem. The equation of motion of the double pendulum system is derived using Lagrange equation of the second kind with multipliers, respecting the contact phenomena. Applications in biomechanical research are hinted at arm gravity motion and a double pendulum impact example.

    Teitelboim, Ayelet; Meir, Noga; Kazes, Miri; Oron, Dan

    2016-05-17

    Pairs of coupled quantum dots with controlled coupling between the two potential wells serve as an extremely rich system, exhibiting a plethora of optical phenomena that do not exist in each of the isolated constituent dots. Over the past decade, coupled quantum systems have been under extensive study in the context of epitaxially grown quantum dots (QDs), but only a handful of examples have been reported with colloidal QDs. This is mostly due to the difficulties in controllably growing nanoparticles that encapsulate within them two dots separated by an energetic barrier via colloidal synthesis methods. Recent advances in colloidal synthesis methods have enabled the first clear demonstrations of colloidal double quantum dots and allowed for the first exploratory studies into their optical properties. Nevertheless, colloidal double QDs can offer an extended level of structural manipulation that allows not only for a broader range of materials to be used as compared with epitaxially grown counterparts but also for more complex control over the coupling mechanisms and coupling strength between two spatially separated quantum dots. The photophysics of these nanostructures is governed by the balance between two coupling mechanisms. The first is via dipole-dipole interactions between the two constituent components, leading to energy transfer between them. The second is associated with overlap of excited carrier wave functions, leading to charge transfer and multicarrier interactions between the two components. The magnitude of the coupling between the two subcomponents is determined by the detailed potential landscape within the nanocrystals (NCs). One of the hallmarks of double QDs is the observation of dual-color emission from a single nanoparticle, which allows for detailed spectroscopy of their properties down to the single particle level. Furthermore, rational design of the two coupled subsystems enables one to tune the emission statistics from single photon

    Full Text Available This paper is an attempt to sketch out a reading of Kafka’s work based on the idea that thephysiognomic principle is the pillar of his grotesque poetics. According to this principle, Kafka’s literarywork is not to be interpreted (i.e. there is no meaning beyond it to look for but it is instead to be read asan experimental machine that immanently produces its own sense. This anti-transcendent reading, whichmakes use of some fundamental philosophical accounts (such as Deleuze and Guattari’s, Wittgenstein’sand Adorno’s, is developed in particular in two directions: on the one side the abolition of the subjectand on the other side the creation of an anti-perspective and anti-metaphorical literature.

    Full Text Available The Double Star Programme (DSP was first proposed by China in March, 1997 at the Fragrant Hill Workshop on Space Science, Beijing, organized by the Chinese Academy of Science. It is the first mission in collaboration between China and ESA. The mission is made of two spacecraft to investigate the magnetospheric global processes and their response to the interplanetary disturbances in conjunction with the Cluster mission. The first spacecraft, TC-1 (Tan Ce means "Explorer", was launched on 29 December 2003, and the second one, TC-2, on 25 July 2004 on board two Chinese Long March 2C rockets. TC-1 was injected in an equatorial orbit of 570x79000 km altitude with a 28° inclination and TC-2 in a polar orbit of 560x38000 km altitude. The orbits have been designed to complement the Cluster mission by maximizing the time when both Cluster and Double Star are in the same scientific regions. The two missions allow simultaneous observations of the Earth magnetosphere from six points in space. To facilitate the comparison of data, half of the Double Star payload is made of spare or duplicates of the Cluster instruments; the other half is made of Chinese instruments. The science operations are coordinated by the Chinese DSP Scientific Operations Centre (DSOC in Beijing and the European Payload Operations Service (EPOS at RAL, UK. The spacecraft and ground segment operations are performed by the DSP Operations and Management Centre (DOMC and DSOC in China, using three ground station, in Beijing, Shanghai and Villafranca.

    Radical-ion-pair reactions, fundamental in photosynthesis and at the basis of the avian magnetic compass mechanism, have been recently shown to offer a rich playground for applying methods and concepts from quantum measurement/quantum information science. We will demonstrate that radical-ion-pair reactions are almost the exact analog of the optical double slit experiment, i.e. Nature has already engineered biochemical reactions performing the act of quantum interference. We will further elaborate on the non-trivial quantum effects pertaining in these reactions and the recent debate on their fundamental theoretical description that these effects have sparked.

  16. Firewalls From Double Purity

    CERN Document Server

    Bousso, Raphael

    2013-01-01

    The firewall paradox is often presented as arising from double entanglement, but I argue that more generally the paradox is double purity. Near-horizon modes are purified by the interior, in the infalling vacuum. Hence they cannot also be pure alone, or in combination with any third system, as demanded by unitarity. This conflict arises independently of the Page time, for entangled and for pure states. It implies that identifications of Hilbert spaces cannot resolve the paradox. Traditional complementarity requires the unitary identification of infalling matter with a scrambled subsystem of the Hawking radiation. Extending this map to the infalling vacuum overdetermines the out-state. More general complementarity maps ("A=R_B", "ER=EPR") founder when the near-horizon zone is pure. I argue that pure-zone states span the microcanonical ensemble, and that this suffices to make the horizon a special place. I advocate that the ability to detect the horizon locally, rather than the degree or probability of violence...

  17. Double Field Theory Inspired Cosmology

    CERN Document Server

    Wu, Houwen

    2014-01-01

    Double field theory proposes a generalized spacetime action possessing manifest T-duality on the level of component fields. We calculate the cosmological solutions of double field theory with vanishing Kalb-Ramond field. It turns out that double field theory provides a more consistent way to construct cosmological solutions than the standard string cosmology. We find two sets of solutions in double field theory cosmology, respecting or violating the strong (weak) constraint. Both sets of solutions naturally contain the pre- and post-big bang evolutions in one single line element. This novel feature opens a window for possible resolution of the cosmic amnesia. We also demonstrate that the scale factor duality in the standard string cosmology is nothing but the T-duality in double field theory. The scale dual dilatons in the standard string cosmology is simply the usual diffeomorphic scalar dilaton $\\phi$ and dual diffeomorphic scalar dilaton $\\tilde\\phi$ in double field theory. Furthermore, we identify the "sh...

    Regardless of the formation mechanism, an exotic object, the double degenerate star (DDS), is introduced and investigated, which is composed of baryonic matter and some unknown fermion dark matter. Different from the simple white dwarfs (WDs), there is additional gravitational force provided by the unknown fermion component inside DDSs, which may strongly affect the structure and the stability of such kind of objects. Many possible and strange observational phenomena connecting with them are concisely discussed. Similar to the normal WD, this object can also experience thermonuclear explosion as type Ia supernova explosion when DDS's mass exceeds the maximum mass that can be supported by electron degeneracy pressure. However, since the total mass of baryonic matter can be much lower than that of WD at Chandrasekhar mass limit, the peak luminosity should be much dimmer than what we expect before, which may throw a slight shadow on the standard candle of SN Ia in the research of cosmology.

  1. GENERALIZED DOUBLE PARETO SHRINKAGE.

    Science.gov (United States)

    Armagan, Artin; Dunson, David B; Lee, Jaeyong

    2013-01-01

    We propose a generalized double Pareto prior for Bayesian shrinkage estimation and inferences in linear models. The prior can be obtained via a scale mixture of Laplace or normal distributions, forming a bridge between the Laplace and Normal-Jeffreys' priors. While it has a spike at zero like the Laplace density, it also has a Student's t-like tail behavior. Bayesian computation is straightforward via a simple Gibbs sampling algorithm. We investigate the properties of the maximum a posteriori estimator, as sparse estimation plays an important role in many problems, reveal connections with some well-established regularization procedures, and show some asymptotic results. The performance of the prior is tested through simulations and an application.

  2. Dual Double Field Theory

    2016-01-01

    We present the dual formulation of double field theory at the linearized level. This is a classically equivalent theory describing the duals of the dilaton, the Kalb-Ramond field and the graviton in a T-duality or O(D,D) covariant way. In agreement with previous proposals, the resulting theory encodes fields in mixed Young-tableau representations, combining them into an antisymmetric 4-tensor under O(D,D). In contrast to previous proposals, the theory also requires an antisymmetric 2-tensor and a singlet, which are not all pure gauge. The need for these additional fields is analogous to a similar phenomenon for "exotic" dualizations, and we clarify this by comparing with the dualizations of the component fields. We close with some speculative remarks on the significance of these observations for the full non-linear theory yet to be constructed.

    The Laser Doppler flowmetry (LDF) is a non-invasive method for estimating the tissular blood flow and speed at a microscopic scale (microcirculation). It is used for medical research as well as for the diagnosis of diseases related to circulatory system tissues and organs including the issues of microvascular flow (perfusion). It is based on the Doppler effect, created by the interaction between the laser light and tissues. LDF measures the mean blood flow in a volume formed by the single laser beam, that penetrate into the skin. The size of this measurement volume is crucial and depends on skin absorption, and is not directly reachable. Therefore, current developments of the LDF are focused on the use of always more complex and sophisticated signal processing methods. On the other hand, laser Double Doppler Flowmeter (FL2D) proposes to use two laser beams to generate the measurement volume. This volume would be perfectly stable and localized at the intersection of the two laser beams. With FL2D we will be able to determine the absolute blood flow of a specific artery. One aimed application would be to help clinical physicians in health care units.

    2014-01-01

    The latest results from the Double Chooz experiment on the neutrino mixing angle $\\theta_{13}$ are presented. A detector located at an average distance of 1050 m from the two reactor cores of the Chooz nuclear power plant has accumulated a live time of 467.90 days, corresponding to an exposure of 66.5 GW-ton-year (reactor power $\\times$ detector mass $\\times$ live time). A revised analysis has boosted the signal efficiency and reduced the backgrounds and systematic uncertainties compared to previous publications, paving the way for the two detector phase. The measured $\\sin^2 2\\theta_{13} = 0.090^{+0.032}_{-0.029}$ is extracted from a fit to the energy spectrum. A deviation from the prediction above a visible energy of 4 MeV is found, being consistent with an unaccounted reactor flux effect, which does not affect the $\\theta_{13}$ result. A consistent value of $\\theta_{13}$ is measured in a rate-only fit to the number of observed candidates as a function of the reactor power, confirming the robustness of the ...

    We show that an alkali atom with a tripod electronic structure can yield rich electromagnetically induced transparency phenomena even at room temperature. In particular we introduce double-double electromagnetically induced transparency wherein signal and probe fields each have two transparency windows. Their group velocities can be matched in either the first or second pair of transparency windows. Moreover signal and probe fields can each experience coherent gain in the second transparency windows. We explain using a semi-classical-dressed-picture to connect the tripod electronic structure to a double-\\Lambda\\ scheme.

    We clarify the relation between various approaches to the manifestly T-duality symmetric string. We explain in detail how the PST covariant doubled string arises from an unusual gauge fixing. We pay careful attention to the role of "spectator" fields in this process and also show how the T-duality invariant doubled dilaton emerges naturally. We extend these ideas to non-Abelian T-duality and show they give rise to the duality invariant formalism based on the semi-Abelian Drinfeld Double. We then develop the N=(0,1) supersymmetric duality invariant formalism.

  17. Gas-filled double glazing

    Goesele, K.; Schuele, W.; Lakatos, B.

    1982-01-01

    On the basis of the results of experiments the sonar and thermal properties of insulated double glazing filled with gas are tested. The sound insulation properties of double glazing can be improved by introducing a gas of a heavy specific weight, such as CO/sub 2/ or SF/sub 6/ into the hollow space. Even gases with a light specific weight produce an improvement in sound insulation; light gases diffuse outwards much more rapidly, however, and can thus be eliminated for practical purposes. The combination of a gas-filled space between the panes and the use of sufficiently heavy compound panes were tested. The thermal properties of insulated double glazing filled with specifically heavy gas gave favourable results with a lower heat transition coefficient. The use of gas to fill double glazing has a particularly favourable effect if the panes are given a heat-reflecting coating in synthetic frames.

    Ruddick, Barry; Gargett, Ann E.

    2003-03-01

    Double-diffusion, the mixing of fluids with two constituents of different molecular diffusivities, was originally discovered in the mid-1800s, forgotten, then rediscovered as an ‘oceanographic curiosity’ a century later. Many oceanographers suspect that double-diffusion has major effects on oceanic water masses and circulation, but direct measurement of the effects has proven difficult. In 1996, a Working Group was formed under the auspices of the Scientific Committee on Ocean Research (SCOR WG108), with the goal to identify progress and barriers to quantifying oceanic double-diffusive fluxes, and make recommendations for further progress. This document gives a brief history of double-diffusion, a review of evidence of its potential effects in the ocean, and gives an overview of the review articles contained in this volume, written by the Working Group members with the above aim in mind.

  19. The Double Love Commandment

    2015-03-01

    Full Text Available The Gospel of Matthew was written during a period of dispute between the Matthean community and their fellow Jews, with the Pharisees playing a leading role. The Matthean community was heir to the same scriptures as its opponents. They continued to have a firm commitment to the Torah, but they developed a distinctive understanding of it based on Jesus’ teaching. The formation of this community is investigated in this article, considering the Mediterranean perspectives of group-oriented societies prevalent in the first century. Such a group provided a sense of self and an interactive support system, where love functioned to bind the group together. The subordinates showed their undivided loyalty towards their superiors because of the favours they received from them, whilst they supported and cared for other members within the group as they care for themselves. Reading the double love commandment of Matthew 22:34−40 from this perspective reveals significant aspects of the community’s identity with regard to their commitment to God and their view of their neighbours.Die Dubbele Liefdesgebod. Die Matteusevangelie is gedurende ’n periode van konfliktussen die Matteusgemeenskap en mede-Jode geskryf met die Fariseërs in ’n leidende rol. Die Matteusgemeenskap het van dieselfde geskrifte as hulle opponente gebruik gemaak. Hulle was steeds aan die Torah lojaal, maar het ’n unieke interpretasie daarvan gehuldig, gebaseer op die onderrig van Jesus. In hierdie artikel word die vorming van die Matteusgemeenskap ondersoek met inagneming van die Mediterreense beskouing van die groepgeoriënteerde gemeenskappe wat tipies van die eerste eeu was. So ’n groep het aan individue ’n bewustheid van eie waarde verskaf te midde van ’n interaktiewe ondersteuningsisteem waarin liefde as samebindende faktor gefunksioneer het.

    The electron spectra emitted when a double capture occurs in N[sup 7+]+He and Ne[sup 8+]+He systems at 10 qkeV collisional energy, allow us to determine the angular distributions of the 3[ell]3[ell] [prime] lines through a special spectra fitting procedure which includes interferences between neighbouring states. It is found that the doubly excited states populated in double capture processes are generally aligned.

  3. Double-Difference Adjoint Tomography

    Science.gov (United States)

    Yuan, Yanhua O.; Simons, Frederik J.; Tromp, Jeroen

    2016-04-01

    We introduce a double-difference method for the inversion of seismic wavespeed structure by adjoint tomography. Differences between seismic observations and model-based predictions at individual stations may arise from factors other than structural heterogeneity, such as errors in the assumed source-time function, inaccurate timings, and systematic uncertainties. To alleviate the corresponding nonuniqueness in the inverse problem, we construct differential measurements between stations, thereby largely canceling out the source signature and systematic errors. We minimize the discrepancy between observations and simulations in terms of differential measurements made on station pairs. We show how to implement the double-difference concept in adjoint tomography, both theoretically and in practice. We compare the sensitivities of absolute and differential measurements. The former provide absolute information on structure along the ray paths between stations and sources, whereas the latter explain relative (and thus higher-resolution) structural variations in areas close to the stations. Whereas in conventional tomography, a measurement made on a single earthquake-station pair provides very limited structural information, in double-difference tomography, one earthquake can actually resolve significant details of the structure. The double-difference methodology can be incorporated into the usual adjoint tomography workflow by simply pairing up all conventional measurements; the computational cost of the necessary adjoint simulations is largely unaffected. Rather than adding to the computational burden, the inversion of double-difference measurements merely modifies the construction of the adjoint sources for data assimilation.

    2014-07-01

    Double field theory proposes a generalized spacetime action possessing manifest T-duality on the level of component fields. We calculate the cosmological solutions of double field theory with vanishing Kalb-Ramond field. It turns out that double field theory provides a more consistent way to construct cosmological solutions than the standard string cosmology. We construct solutions for vanishing and non-vanishing symmetry preserving dilaton potentials. The solutions assemble the pre- and post-big bang evolutions in one single line element. Our results show a smooth evolution from an anisotropic early stage to an isotropic phase without any special initial conditions in contrast to previous models. In addition, we demonstrate that the contraction of the dual space automatically leads to both an inflation phase and a decelerated expansion of the ordinary space during different evolution stages.

    Tunnelling magnetoresistance (TMR) in polycrystalline double perovskites has been an important research topic for more than a decade now, where the nature of the insulating tunnel barrier is the core issue of debate. Other than the nonmagnetic grain boundaries as conventional tunnel barriers, intragrain magnetic antiphase boundaries (APB) as well as magnetically frustrated grain surfaces have also been proposed to act as tunnel barriers in Sr2FeMoO6. In this review, the present state of the debate has been discussed briefly and how the physical state of the material can affect the magnetoresistance signal of double perovskites in many different ways has been pointed out.

    A new scheme for a double-slit experiment in the time domain is presented. Phase-stabilized few-cycle laser pulses open one to two windows (slits) of attosecond duration for photoionization. Fringes in the angle-resolved energy spectrum of varying visibility depending on the degree of which-way information are measured. A situation in which one and the same electron encounters a single and a double slit at the same time is observed. The investigation of the fringes makes possible interferometry on the attosecond time scale. From the number of visible fringes, for example, one derives that the slits are extended over about 500 as.

    This invention describes a new method of constructing double-stranded DNA (dsDNA) microarrays based on the use of pre-synthesized or natural DNA duplexes without a stem-loop structure. The complementary oligonucleotide chains are bonded together by a novel connector that includes a linker for immobilization on a matrix. A non-enzymatic method for synthesizing double-stranded nucleic acids with this novel connector enables the construction of inexpensive and robust dsDNA/dsRNA microarrays. DNA-DNA and DNA-protein interactions are investigated using the microarrays.

  13. Topics in Double Field Theory

    Science.gov (United States)

    Kwak, Seung Ki

    The existence of momentum and winding modes of closed string on a torus leads to a natural idea that the field theoretical approach of string theory should involve winding type coordinates as well as the usual space-time coordinates. Recently developed double field theory is motivated from this idea and it implements T-duality manifestly by doubling the coordinates. In this thesis we will mainly focus on the double field theory formulation of different string theories in its low energy limit: bosonic, heterotic, type II and its massive extensions, and N = 1 supergravity theory. In chapter 2 of the thesis we study the equivalence of different formulations of double field theory. There are three different formulations of double field theory: background field E formulation, generalized metric H formulation, and frame field EAM formulation. Starting from the frame field formalism and choosing an appropriate gauge, the equivalence of the three formulations of bosonic theory are explicitly verified. In chapter 3 we construct the double field theory formulation of heterotic strings. The global symmetry enlarges to O( D, D + n) for heterotic strings and the enlarged generalized metric features this symmetry. The structural form of bosonic theory can directly be applied to the heterotic theory with the enlarged generalized metric. In chapter 4 we develop a unified framework of double field theory for type II theories. The Ramond-Ramond potentials fit into spinor representations of the duality group O( D, D) and the theory displays Spin+( D, D) symmetry with its self-duality relation. For a specific form of RR 1-form the theory reduces to the massive deformation of type IIA theory due to Romans. In chapter 5 we formulate the N = 1 supersymmetric extension of double field theory including the coupling to n abelian vector multiplets. This theory features a local O(1, 9 + n) x O(1, 9) tangent space symmetry under which the fermions transform. (Copies available exclusively from

    Double photoionization of atomic oxygen was first measured at Aladdin, a second-generation synchrotron source, at lower resolution (Angel and Samson, PRA, 38, 5573, 1988). Here we present new experimental and theoretical results for the direct double photoionization of atomic oxygen. The experiment was performed at the Advanced Light Source for photon energies near the double-ionization threshold, revealing rich resonance structures converging to multiple single-ionization thresholds. State-of-the-art calculations were performed using the R-matrix with pseudostates (RMPS) method (P. G. Burke, R-matrix Theory of Atomic Collisions, Springer 2011) as implemented by Gorczya and Badnell (JPB, 30, 3897, 1997), and recently applied, in a converged representation, to the double photoionization of helium (T. W. Gorczyca et al., JPB, 46, 195201, 2013). The much-larger calculation required for oxygen, due to the many target state symmetries compared to helium, necessitated a parallel RMPS approach. Comparison between theoretical and experimental results shows overall qualitative agreement but also some puzzling discrepancies: experimental features that are not reproduced by the RMPS calculations.

    Astronomers have long tracked double stars in efforts to find those that are gravitationally-bound binaries and then to determine their orbits. Early catalogues by the Herschels, Struves, and others began with their own discoveries. In 1906 court reporter and amateur astronomer Sherburne Wesley Burnham published a massive double star catalogue containing data from many observers on more than 13,000 systems. Lick Observatory astronomer Robert Grant Aitken produced a much larger catalogue in 1932 and coordinated with Robert Innes of Johannesburg, who catalogued the southern systems. Aitken maintained and expanded Burnham's records of observations on handwritten file cards, and eventually turned them over to the Lick Observatory, where astrometrist Hamilton Jeffers further expanded the collection and put all the observations on punched cards. With the aid of Frances M. "Rete" Greeby he made two catalogues: an Index Catalogue with basic data about each star, and a complete catalogue of observations, with one observation per punched card. He enlisted Willem van den Bos of Johannesburg to add southern stars, and together they published the Index Catalogue of Visual Double Stars, 1961.0. As Jeffers approached retirement he became greatly concerned about the disposition of the catalogues. He wanted to be replaced by another "double star man," but Lick Director Albert E. Whitford had the new 120-inch reflector, the world's second largest telescope, and he wanted to pursue modern astrophysics instead. Jeffers was vociferously opposed to turning over the card files to another institution, and especially against their coming under the control of Kaj Strand of the United States Naval Observatory. In the end the USNO got the files and has maintained the records ever since, first under Charles Worley, and, since 1997, under Brian Mason. Now called the Washington Double Star Catalog (WDS), it is completely online and currently contains more than 1,200,000 measures of more than 125

  7. Pathways to doubled haploidy: chromosome doubling during androgenesis.

    2008-01-01

    Production of doubled haploid (DH) plants through androgenesis induction is a promising and convenient alternative to conventional selfing techniques for the generation of pure lines for breeding programs. This process comprises two main steps: induction of androgenesis and duplication of the haploid genome. Such duplication is sometimes indirectly induced by the treatments used to promote androgenic development. But usually, an additional step of direct chromosome doubling must be included in the protocol. Duplication of the haploid genome of androgenic individuals has been thought to occur through three mechanisms: endoreduplication, nuclear fusion and c-mitosis. In this review we will revise and analyze the evidences supporting each of the proposed mechanisms and their relevance during androgenesis induction, embryo/callus development and plant regeneration. Special attention will be devoted to nuclear fusion, whose evidences are accumulating in the last years.

  8. Double layers and double wells in arbitrary degenerate plasmas

    2016-06-01

    Using the generalized hydrodynamic model, the possibility of variety of large amplitude nonlinear excitations is examined in electron-ion plasma with arbitrary electron degeneracy considering also the ion temperature effect. A new energy-density relation is proposed for plasmas with arbitrary electron degeneracy which reduces to the classical Boltzmann and quantum Thomas-Fermi counterparts in the extreme limits. The pseudopotential method is employed to find the criteria for existence of nonlinear structures such as solitons, periodic nonlinear structures, and double-layers for different cases of adiabatic and isothermal ion fluids for a whole range of normalized electron chemical potential, η0, ranging from dilute classical to completely degenerate electron fluids. It is observed that there is a Mach-speed gap in which no large amplitude localized or periodic nonlinear excitations can propagate in the plasma under consideration. It is further revealed that the plasma under investigation supports propagation of double-wells and double-layers the chemical potential and Mach number ranges of which are studied in terms of other plasma parameters. The Mach number criteria for nonlinear waves are shown to significantly differ for cases of classical with η0 0 regimes. It is also shown that the localized structure propagation criteria possess significant dissimilarities for plasmas with adiabatic and isothermal ions. Current research may be generalized to study the nonlinear structures in plasma containing positrons, multiple ions with different charge states, and charged dust grains.

    Double trisomy is rare and the only case reported in the literature died soon after birth. We present another case of double trisomy (48XYY, +18) in a male neonate, who was born to a 28-year-old gravida three parity one mother at 35 weeks of gestation. The baby had features of trisomy 18. Karyotype of the patient showed 48, XYY, +18, Ish (DYZ3*2), (D18Z1*3), nuc ish (DYZ3*2), (D18Z1*3) . The patient had clinical features of trisomy 18. There was no family history of diabetes mellitus and no exposure to chemicals. It has been suggested that the rarity of Y-chromosome involvement in trisomy 18 may be due to discrepancy between the sexes.

    We develop doubled-coordinate field theory to determine the α′ corrections to the massless sector of oriented bosonic closed string theory. Our key tool is a string current algebra of free left-handed bosons that makes O(D,D) T-duality manifest. While T-dualities are unchanged, diffeomorphisms and b-field gauge transformations receive corrections, with a gauge algebra given by an α′-deformation of the duality-covariantized Courant bracket. The action is cubic in a double metric field, an unconstrained extension of the generalized metric that encodes the gravitational fields. Our approach provides a consistent truncation of string theory to massless fields with corrections that close at finite order in α′.

    2003-12-01

    We analyze Neuberger’s double-pass algorithm for the matrix-vector multiplication R(H)ṡY [where R(H) is (n-1,n)th degree rational polynomial of positive definite operator H], and show that the number of floating-point operations is independent of the degree n, provided that the number of sites is much larger than the number of iterations in the conjugate gradient. This implies that the matrix-vector product (H)-1/2Y≃R(n-1,n)(H)ṡY can be approximated to very high precision with sufficiently large n, without noticeably extra costs. Further, we show that there exists a threshold nT such that the double-pass is faster than the single pass for n>nT, where nT≃12 25 for most platforms.

    Nuclei with double strangeness (S = -2) provide the key information to understand Baryon-Baryon interaction under the SU(3)f symmetry. Therefore we have carried out the experiments at KEK for quarter a century. Recently, the interaction in S = -2 sector is noted to derive the information of the EOS of neutron star. The Lambda-Lambda interaction has been presented to be weak attractive by NAGARA event which showed the production and decay of 6He double-hypernucleus. The event also presented the lower mass limit of H dibaryon. In other five events, we obtained the knowledge about an excitation level of 10Be double-hypernucleus under the consistency with NAGARA event. Moreover, very recently, we have discovered a Xi-14N system which was deeply bound far from the atomic 3D level (0.17 MeV) for a captured Xi hyperon. Since a 8Li nucleus was associated with the decay of one of twin-hypernuclei, the event was uniquely identified as Xi- + 14N ==> 10BeL + 5HeL. The system was selected from 8 million pictures on the test running for development of ``Overall Scanning'' to be used in the coming experiment. This is the first evidence of Xi hypernucleus to be bound and it is impacting for the study of Xi-N interaction. At J-PARC facility, for the further study of hyperon-hyperon interaction, we plan to perform the E07 experiment at J-PARC. In the workshop, we will review the above knowledge obtained by the experiments at KEK-PS, and discuss developed technologies to detected 102 or more double-hypernuclei in the E07 experiment at J-PARC.

    2002-01-01

    We report a quantum eraser experiment which actually uses a Young double-slit to create interference. The experiment can be considered an optical analogy of an experiment proposed by Scully, Englert and Walther. One photon of an entangled pair is incident on a Young double-slit of appropriate dimensions to create an interference pattern in a distant detection region. Quarter-wave plates, oriented so that their fast axes are orthogonal, are placed in front of each slit to serve as which-path markers. The quarter-wave plates mark the polarization of the interfering photon and thus destroy the interference pattern. To recover interference, we measure the polarization of the other entangled photon. In addition, we perform the experiment under delayed erasure circumstances.

  16. Supergravity with Doubled Spacetime Structure

    CERN Document Server

    Ma, Chen-Te

    2016-01-01

    Double Field Theory (DFT) is a low-energy effective theory of a manifestly $O(D,D)$ invariant formulation of the closed string theory when the toroidally compact dimensions are present. The theory is based on a doubled spacetime structure and, in order to preserve the gauge symmetry provided by the invariance under generalized diffeomorphisms, a constraint has to be imposed on fields and gauge parameters. In this paper, we propose a DFT-inspired Supergravity by using a suitable {\\em star product} with the aim of studying the corresponding algebraic structure. We get a consistent DFT in which also an orthogonality condition of momenta is necessary for having a closed gauge algebra. In constructing this theory, we start from the simplest case of doubling one spatial dimension where the action is uniquely determined, without any ambiguities, by the gauge symmetry. Then, the extension to the generic $O(D, D)$ case is studied and it results to be consistent with the closed string field theory.

    Striking examples of episodic jet activity in active galactic nuclei (AGN) are the double-double radio galaxies (DDRGs) with two pairs of lobes emerging from the same central engine. The number of DDRGs reported so far is very limited, and it is important to identify more of these to provide a significant statistical overview of the conditions to trigger the jets and the role of jets in terms of feedback mechanisms that affect the host galaxies. Although most DDRGs were believed initially to be giant radio sources with sizes more than a Mpc, a significant number of smaller sized candidate DDRGs have also been identified in our recent study. We started GMRT observation of this sample to confirm that the sources are related to distinct epochs of nuclear activity. In addition to this radio observation we have also investigated the properties of the host galaxies and their environments to understand the triggering mechanisms for recurrent jet emission. Here, I will highlight the main results from these observations and discuss on the possible scenarios responsible for the episodic activity in different types of DDRGs .

  2. Enhanced nonlinear susceptibility via double-double electromagnetically induced transparency

    2016-11-01

    We investigate the nonlinear optical susceptibility of an alkali-metal atom with tripod electronic configuration responsible for generating cross-phase modulation and self-phase modulation under the condition of double-double electromagnetically induced transparency. Our investigation demonstrates an enhancement in the nonlinear optical susceptibility of an alkali-metal atom by a factor of 1000 in the region of the second transparency window. This enhancement is in comparison with the atom's susceptibility in the first transparency window for the same parameters under the same conditions. Nonlinear-absorption enhancement arises by canceling Raman-gain generation, which arises when the probe and signal fields have equal intensities. At the center of the second transparency window, we obtain the condition required to attain a nonvanishing nonlinear optical susceptibility. In the bare-state picture, the coupling field must be off resonant from a bare-to-bare-state transition, while working in the semiclassical dressed picture required the signal field to be tuned off resonantly with a bare-to-dressed-state transition. The relation that governs the values of coupling- and signal-field detuning are also obtained. Our scheme exhibits the fact that the second transparency window has advantages over the first transparency window with respect to obtaining an enhanced Kerr effect, and our calculation includes simulation of both low-temperature and Doppler-broadened regimes.

    The coherent generation of light, from masers to lasers, relies upon the specific structure of the individual emitters that lead to gain. Devices operating as lasers in the few-emitter limit provide opportunities for understanding quantum coherent phenomena, from terahertz sources to quantum communication. Here we demonstrate a maser that is driven by single-electron tunneling events. Semiconductor double quantum dots (DQDs) serve as a gain medium and are placed inside a high-quality factor microwave cavity. We verify maser action by comparing the statistics of the emitted microwave field above and below the maser threshold. Copyright © 2015, American Association for the Advancement of Science.

From experimental point of view, a very large number of different techniques are or have been used increasing the sensitivity of this experiments quite a lot (the factor of 10{sup 4} in the last 20 years). In future, in spite of several difficulties, the sensitivity would be increased further, keeping the interest of this very important process. (author) 4 figs., 5 tabs., 21 refs.

    The motivation behind implementing a booster double harmonic include the reduced transverse space charge force from a reduced peak beam current and reduced momentum spread of the beam, both of which can be achieved from flattening the RF bucket. RF capture and acceleration of polarized protons (PP) is first set up in the single harmonic mode with RF harmonic h=1. Once capture and acceleration have been set up in the single harmonic mode, the second harmonic system is brought on and programmed to operate in concert with the single harmonic system.

    Full Text Available In the past ten years, neutrino oscillation experiments have provided the incontrovertible evidence that neutrinos mix and have finite masses. These results represent the strongest demonstration that the electroweak Standard Model is incomplete and that new Physics beyond it must exist. In this scenario, a unique role is played by the Neutrinoless Double Beta Decay searches which can probe lepton number conservation and investigate the Dirac/Majorana nature of the neutrinos and their absolute mass scale (hierarchy problem with unprecedented sensitivity. Today Neutrinoless Double Beta Decay faces a new era where large-scale experiments with a sensitivity approaching the so-called degenerate-hierarchy region are nearly ready to start and where the challenge for the next future is the construction of detectors characterized by a tonne-scale size and an incredibly low background. A number of new proposed projects took up this challenge. These are based either on large expansions of the present experiments or on new ideas to improve the technical performance and/or reduce the background contributions. In this paper, a review of the most relevant ongoing experiments is given. The most relevant parameters contributing to the experimental sensitivity are discussed and a critical comparison of the future projects is proposed.

  9. Infinite sets and double binds.

    Science.gov (United States)

    Arden, M

    1984-01-01

    There have been many attempts to bring psychoanalytical theory up to date. This paper approaches the problem by discussing the work of Gregory Bateson and Ignacio Matte-Blanco, with particular reference to the use made by these authors of Russell's theory of logical types. Bateson's theory of the double bind and Matte-Blanco's bilogic are both based on concepts of logical typing. It is argued that the two theories can be linked by the idea that neurotic symptoms are based on category errors in thinking. Clinical material is presented from the analysis of a middle-aged woman. The intention is to demonstrate that the process of making interpretations can be thought of as revealing errors in thinking. Changes in the patient's inner world are then seen to be the result of clarifying childhood experiences based on category errors. Matte-Blanco's theory of bilogic and infinite experiences is a re-evaluation of the place of the primary process in mental life. It is suggested that a combination of bilogic and double bind theory provides a possibility of reformulating psychoanalytical theory.

    2008-12-01

    Double Exposure, Photographing Climate Change, is a fine-art photography exhibition that examines climate change through the prism of melting glaciers. The photographs are twinned shots of glaciers, taken in the mid-20th century by world-renowned photographer Brad Washburn, and in the past two years by Boston journalist/photographer David Arnold. Arnold flew in Washburn's aerial "footprints", replicating stunning black and white photographs, and documenting one irreversible aspect of climate change. Double Exposure is art with a purpose. It is designed to educate, alarm and inspire its audiences. Its power lies in its beauty and the shocking changes it has captured through a camera lens. The interpretive text, guided by numerous experts in the fields of glaciology, global warming and geology, helps convey the message that climate change has already forced permanent changes on the face of our planet. The traveling exhibit premiered at Boston's Museum of Science in April and is now criss-crossing the nation. The exhibit covers changes in the 15 glaciers that have been photographed as well as related information about global warming's effect on the planet today.

  11. Double-Front Detonation Waves

    Science.gov (United States)

    Gubin, S. A.; Sumskoi, S. I.; Victorov, S. B.

    According to the theory of detonation, in a detonation wave there is a sound plane, named Chapman-Jouguet (CJ) plane. There are certain stationary parameters for this plane. In this work the possibility of the second CJ plane is shown. This second CJ plane is stationary as well. The physical mechanism of non-equilibrium transition providing the existence of the second CJ plane is presented. There is a non-equilibrium state, when the heat is removed from the reaction zone and the heat capacity decreases sharply. As a result of this non-equilibrium state, the sound velocity increases, and the local supersonic zone with second sonic plane (second CJ plane) appears. So the new mode of detonation wave is predicted. Equations describing this mode of detonation are presented. The exact analytical solution for the second CJ plane parameters is obtained. The example of double-front detonation in high explosive (TNT) is presented. In this double-front structure "nanodiamond-nanographite" phase transition takes place in condensed particles of detonation products.

    A double Dirac cone is realized at the center of the Brillouin zone of a two-dimensional phononic crystal (PC) consisting of a triangular array of core-shell-structure cylinders in water. The double Dirac cone is induced by the accidental degeneracy of two double-degenerate Bloch states. Using a perturbation method, we demonstrate that the double Dirac cone is composed of two identical and overlapping Dirac cones whose linear slopes can also be accurately predicted from the method. Because the double Dirac cone occurs at a relatively low frequency, a slab of the PC can be mapped onto a slab of zero refractive index material by using a standard retrieval method. Total transmission without phase change and energy tunneling at the double Dirac point frequency are unambiguously demonstrated by two examples. Potential applications can be expected in diverse fields such as acoustic wave manipulations and energy flow control.

    Buffing, Maarten G A; Kasemets, Tomas

    2016-01-01

    The cross section for transverse momentum dependent double parton scattering involves transverse momentum dependent double parton distributions (DTMDs). In the region of perturbative transverse momentum the DTMDs can be matched onto collinear double parton distributions. We present the framework and results for this matching, as well as the evolution equations for DTMDs in the region of large distance between the two partons. We discuss explicit results for one-loop matching coefficients and evolution kernels.

    We calculate the complete double logarithmic contribution to cross sections for semi-inclusive hadron production in the modified minimal-subtraction (MS) scheme by applying dimensional regularization to the double logarithm approximation. The full double logarithmic contribution to the coefficient functions for inclusive hadron production in electron-positron annihilation is obtained in this scheme for the first time. Our result agrees with all fixed order results in the literature, which extend to next-next-to-leading order. (orig.)

  15. Approximation by double Walsh polynomials

    1992-01-01

    Full Text Available We study the rate of approximation by rectangular partial sums, Cesàro means, and de la Vallée Poussin means of double Walsh-Fourier series of a function in a homogeneous Banach space X. In particular, X may be Lp(I2, where 1≦p<∞ and I2=[0,1×[0,1, or CW(I2, the latter being the collection of uniformly W-continuous functions on I2. We extend the results by Watari, Fine, Yano, Jastrebova, Bljumin, Esfahanizadeh and Siddiqi from univariate to multivariate cases. As by-products, we deduce sufficient conditions for convergence in Lp(I2-norm and uniform convergence on I2 as well as characterizations of Lipschitz classes of functions. At the end, we raise three problems.

  16. Doubling bialgebras of rooted trees

    Science.gov (United States)

    Mohamed, Mohamed Belhaj; Manchon, Dominique

    2017-01-01

    The vector space spanned by rooted forests admits two graded bialgebra structures. The first is defined by Connes and Kreimer using admissible cuts, and the second is defined by Calaque, Ebrahimi-Fard and the second author using contraction of trees. In this article, we define the doubling of these two spaces. We construct two bialgebra structures on these spaces which are in interaction, as well as two related associative products obtained by dualization. We also show that these two bialgebras verify a commutative diagram similar to the diagram verified Calaque, Ebrahimi-Fard and the second author in the case of rooted trees Hopf algebra, and by the second author in the case of cycle-free oriented graphs.

  17. Double Semions in Arbitrary Dimension

    Science.gov (United States)

    Freedman, Michael H.; Hastings, Matthew B.

    2016-10-01

    We present a generalization of the double semion topological quantum field theory to higher dimensions, as a theory of {d-1} dimensional surfaces in a d dimensional ambient space. We construct a local Hamiltonian that is a sum of commuting projectors and analyze the excitations and the ground state degeneracy. Defining a consistent set of local rules requires the sign structure of the ground state wavefunction to depend not just on the number of disconnected surfaces, but also upon their higher Betti numbers through the semicharacteristic. For odd d the theory is related to the toric code by a local unitary transformation, but for even d the dimension of the space of zero energy ground states is in general different from the toric code and for even {d > 2} it is also in general different from that of the twisted {Z_2} Dijkgraaf-Witten model.

    We have experimentally investigated the double-photoionization process in C{sub 6}BrF{sub 5} using monochromatized synchrotron radiation. We compare our results with previously published data for partially deuterated benzene (C{sub 6}H{sub 3}D{sub 3}) over a wide range of photon energies from threshold to 270 eV. A broad resonance in the ratio of doubly to singly charged parent ions at about 65 eV appears shifted in energy compared to benzene data. This shift is due to the difference in the bond lengths in two molecules. A simple model can explain the shape of this resonance. At higher photon energies, we observe another broad resonance that can be explained as a second harmonic of the first resonance.

    It is shown that the contribution from double parton scattering to the inclusive double heavy meson yield is quite comparable with the usually considered mechanism of their production at the LHC energy. For some pairs of heavy flavored quarks in the final state the double parton scattering will be a dominant mode of their production.

In particular, we find how certain delicate limits of Feynman diagrams play an important role in obtaining this equivalence.

    1987-05-01

    Various mechanisms for driving double layers in plasmas are briefly described, including applied potential drops, currents, contact potentials, and plasma expansions. Some dynamical features of the double layers are discussed. These features, as seen in simulations, laboratory experiments, and theory, indicate that double layers and the currents through them undergo slow oscillations which are determined by the ion transit time across an effective length of the system in which double layers form. It is shown that a localized potential dip forms at the low potential end of a double layer, which interrupts the electron current through it according to the Langmuir criterion, whenever the ion flux into the double is disrupted. The generation of electric fields perpendicular to the ambient magnetic field by contact potentials is also discussed. Two different situations were considered; in one, a low-density hot plasma is sandwiched between high-density cold plasmas, while in the other a high-density current sheet permeates a low-density background plasma. Perpendicular electric fields develop near the contact surfaces. In the case of the current sheet, the creation of parallel electric fields and the formation of double layers are also discussed when the current sheet thickness is varied. Finally, the generation of electric fields and double layers in an expanding plasma is discussed.

Two type cloak materials are proposed and installed in the each layer, respectively. The outer layer cloak of the GL double layered cloak has the invisible function, the inner layer cloak has fully absorption function. The GL double layered metamaterials are weak degenerative and weak dispersive. When the source is located outside of the GL double layered cloak, the excited EM wave field propagation outside of the double layered cloak is as same as in free space and never be disturbed by the cloak; also, the exterior EM wave can not penetrate into the inner layer and concealment. When local sources are located inside of the GL double cloaked concealment with the normal EM materials, the excited EM wave is propagating under Maxwell equation governing, it is complete absorbed by the inner layer cloak of GL double cloak and...

    Double walled or double containment piping is considered for use in the ITER international project and other next-generation fusion device designs to provide an extra barrier for tritium gas and other radioactive materials. The extra barrier improves confinement of these materials and enhances safety of the facility. This paper describes some of the design challenges in designing double containment piping systems. There is also a brief review of a few operating experiences of double walled piping used with hazardous chemicals in different industries. This paper recommends approaches for the reliability analyst to use to quantify leakage from a double containment piping system in conceptual and more advanced designs. The paper also cites quantitative data that can be used to support such reliability analyses.

    2002-02-03

    The peer review process in medical sciences is much debated. The method is not yet evidence based. Who are the reviewers and how do they perform? They are "independent" experts. As such they are bound to be involved in research similar to that outlined in the manuscript. Very often they are contestant in the same race. That is why the author consider the double blind method, where the author is blinded and the reviewer masked from each other's identity, the best choice. Nevertheless in very many scientific journals of high quality and envied impact factors do not blind the identity of the authors. Science is a race for fame, self accomplishment and also a means to get grants for pursuing the scientific research. Only success is able to provide resources for expensive scientific research. There is no fail-safe method against bias in grant giving and editorial process. In the tidal wave of electronic information it is mandatory to help in differentiating between signal and noise in science. Peer review is the best method to protect readers from the trash of uncontrolled publications in medical science.

    2016-12-01

    The Asteroid Impact Deflection Assessment (AIDA) mission will be the first space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic impactor. AIDA is a joint ESA-NASA cooperative project, consisting of the NASA Double Asteroid Redirection Test (DART) kinetic impactor mission and the ESA Asteroid Impact Mission (AIM) which is the rendezvous spacecraft. The AIDA target is the near-Earth binary asteroid 65803 Didymos. During the Didymos close approach to Earth in October, 2022, the DART spacecraft will impact the Didymos secondary at 6 km/s and deflect its trajectory, changing the orbital period of the binary. This change can be measured by Earth-based optical and radar observations. The primary goals of AIDA are to (1) perform a full-scale demonstration of asteroid deflection by kinetic impact; (2) measure the resulting deflection; and (3) validate and improve models for momentum transfer in high-speed impacts on an asteroid. The combined DART and AIM missions will provide the first measurements of momentum transfer efficiency from a kinetic impact at full scale on an asteroid, where the impact conditions of the projectile are known, and physical properties and internal structures of the target asteroid are also characterized. In addition to a measurable change in the binary orbit period, the DART kinetic impact is predicted to induce forced librations of the Didymos secondary of up to several degrees amplitude. It will furthermore make a crater that will be studied in detail by the AIM spacecraft, and it will release a volume of particulate ejecta that may be directly observable from Earth or even resolvable as a coma or an ejecta tail by ground-based telescopes. Updates will be given on DART status and study results.

    2013-03-15

    Double hard scattering in proton-proton collisions is described in terms of double parton distributions. We derive bounds on these distributions that follow from their interpretation as probability densities, taking into account all possible spin correlations between two partons in an unpolarized proton. These bounds constrain the size of the polarized distributions and can for instance be used to set upper limits on the effects of spin correlations in double hard scattering. We show that the bounds are stable under leading-order DGLAP evolution to higher scales.

    Presented is a theoretical study of double-clad Er-doped fiber power amplifier(EDFA). Two kinds of double clad fibers(DCF) with rectangular and "flower" inner clad shapes are studied, and these fibers have different coupling constants and propagation losses. We calculate the effective pump power absorption ratio along the fiber with different coupling constants from the first cladding to the doped core and with different propagation losses for the power in the inner cladding. Then the gains of the double clad Er-doped fiber amplifiers versus fiber lengths are calculated using the EDFA model based on propagation and rate equations of a homogeneous, two-level medium.

    A new class of stationary double layer structure, with three or more distinct steps, is demonstrated in the laboratory. A large monotonic potential increase results from a series of smaller double layers. In many respects, these double layer structures resemble those inferred from satellite measurements of auroral double layers. This new class of double layer appears to depend on turbulence for its existence and to be a hybrid structure, intermediate between anomalous resistivity and BGK double layers.

The experiments are performed in a Q-machine plasma and the double layers are generated by applying a positive step potential to a cold collector plate terminating the plasma column. The double layer is created...... at the grounded plasma source just after the pulse is applied and it propagates towards the collector with a speed around the ion acoustic speed. When the collector is biased positively, large oscillations are obserced in the plasma current. These oscillations are found to be related to a recurring formation...... difference is applied between two plasmas in a Q-machine with two sources. In this case a stationary double layer forms in the plasma column, but the low potential tail is subject to "back and forth" oscillations leading to large amplitude current oscillations....

    Sample, C; Golovin, A A

    2007-09-01

    The nonlinear dynamics of a biological double membrane that consists of two coupled lipid bilayers, typical of some intracellular organelles such as mitochondria or nuclei, is studied. A phenomenological free-energy functional is formulated in which the curvatures of the two parts of the double membrane and the distance between them are coupled to the lipid chemical composition. The derived nonlinear evolution equations for the double-membrane dynamics are studied analytically and numerically. A linear stability analysis is performed, and the domains of parameters are found in which the double membrane is stable. For the parameter values corresponding to an unstable membrane, numerical simulations are performed that reveal various types of complex dynamics, including the formation of stationary, spatially periodic patterns.

  20. The Topology of Double Field Theory

    CERN Document Server

    Hassler, Falk

    2016-01-01

    We describe the doubled space of Double Field Theory as a group manifold $G$ with an arbitrary generalized metric. Local information from the latter is not relevant to our discussion and so $G$ only captures the topology of the doubled space. Strong Constraint solutions are maximal isotropic submanifold $M$ in $G$. We construct them and their Generalized Geometry in Double Field Theory on Group Manifolds. In general, $G$ admits different physical subspace $M$ which are T-dual to each other. By studying two examples, we reproduce the topology changes induced by T-duality with non-trivial $H$-flux which were discussed by Bouwknegt, Evslin and Mathai [hep-th/0306062].

    2015-01-01

    Probing neutrinoless double beta decay is one of the primary goals for SNO+, SNOLAB's multi-purpose neutrino detector. In order to achieve this goal the SNO detector has been adapted so that it can be filled with Te-loaded liquid scintillator. During the initial double beta phase the target loading is 0.3% natural Te, which equates to $\\sim790$ kg of double beta isotope. Estimating the sensitivity to neutrinoless double beta decay requires a well understood background model. For SNO+ this is provided by a comprehensive study considering all possible background contributions, whether they originate from within the liquid scintillator cocktail, the surrounding parts of the detector or other irreducible backgrounds. Given these considerations, for five years running in the initial phase, the expected sensitivity is $T_{1/2}^{0\

  5. The Doubling of Stellar Black Hole Nuclei

    2012-01-01

    It is strongly believed that Andromeda's double nucleus signals a disk of stars revolving around its central super-massive black hole on eccentric Keplerian orbits with nearly aligned apsides. A self-consistent stellar dynamical origin for such apparently long-lived alignment has so far been lacking, with indications that cluster self-gravity is capable of sustaining such lopsided configurations if and when stimulated by external perturbations. Here, we present results of N-body simulations which show unstable counter-rotating stellar clusters around super-massive black holes saturating into uniformly precessing lopsided nuclei. The double nucleus in our featured experiment decomposes naturally into a thick eccentric disk of apo-apse aligned stars which is embedded in a lighter triaxial cluster. The eccentric disk reproduces key features of Keplerian disk models of Andromeda's double nucleus; the triaxial cluster has a distinctive kinematic signature which is evident in HST observations of Andromeda's double ...

  6. Frequency Doubling Broadband Light in Multiple Crystals

    Energy Technology Data Exchange (ETDEWEB)

    ALFORD,WILLIAM J.; SMITH,ARLEE V.

    2000-07-26

    The authors compare frequency doubling of broadband light in a single nonlinear crystal with doubling in five crystals with intercrystal temporal walk off compensation, and with doubling in five crystals adjusted for offset phase matching frequencies. Using a plane-wave, dispersive numerical model of frequency doubling they study the bandwidth of the second harmonic and the conversion efficiency as functions of crystal length and fundamental irradiance. For low irradiance the offset phase matching arrangement has lower efficiency than a single crystal of the same total length but gives a broader second harmonic bandwidth. The walk off compensated arrangement gives both higher conversion efficiency and broader bandwidth than a single crystal. At high irradiance, both multicrystal arrangements improve on the single crystal efficiency while maintaining broad bandwidth.

    In the last few years the search for neutrinoless double beta decay has evolved from being almost a marginal activity in neutrino physics to one of the highest priorities for understanding neutrinos and the origin of mass. There are two main reasons for this paradigm shift: the discovery of neutrino oscillations, which clearly established the existence of massive neutrinos; and the existence of an unconfirmed, but not refuted, claim of evidence for neutrinoless double decay in 76Ge. As a consequence, a new generation of experiments, employing different detection techniques and {\\beta}{\\beta} isotopes, is being actively promoted by experimental groups across the world. In addition, nuclear theorists are making remarkable progress in the calculation of the neutrinoless double beta decay nuclear matrix elements, thus eliminating a substantial part of the theoretical uncertainties affecting the particle physics interpretation of this process. In this report, we review the main aspects of the double beta decay pro...

  8. Double Fell bundles and Spectral triples

    CERN Document Server

    Martins, Rachel A D

    2007-01-01

    As a natural and canonical extension of Kumjian's Fell bundles over groupoids \\cite{fbg}, we give a definition for a double Fell bundle (a double category) over a double groupoid. We show that finite dimensional double category Fell line bundles tensored with their dual with $S^o$-reality satisfy the finite real spectral triples axioms but not necessarily orientability. This means that these product bundles with noncommutative algebras can be regarded as noncommutative compact manifolds more general than real spectral triples as they are not necessarily orientable. By construction, they unify the noncommutative geometry axioms and hence provide an algebraic enveloping structure for finite spectral triples to give the Dirac operator $D$ new algebraic and geometric structures that are otherwise missing in the transition from Fredholm operator to Dirac operator. The Dirac operator in physical applications as a result becomes less ad hoc. The new noncommutative space we present is a complex line bundle over a dou...

    A large number of duplication monstrosities have been observed in cattle, sheep, pigs, horses, goats, cats and dogs, ever since the publication of the famous woodcut of a swine double monster by J. S. Brant in Basel in 1496, better known as the "wunderbare Sau von Landser im Elsass". Albrecht Dürer also made a woodcut of this double monster in front of the village Landser in 1496. A picture of a deer double monster was published in 1603 by Heinrich Ulrich in Germany. In the monograph De monstrorum causis, natura et differentiis ..., published by the Italian Fortunius Licetus in 1616 pictures of double monsters being half man half dog are found. These fantasy figures have been popular for a long time and were supposed to be really in existence. Apart from these fantasy figures many pictures are known from real veterinary double monsters. U. Aldrovandus described in 1642 in his Monstrorum historia, besides many fantasy figures, also real human and veterinary double monsters and he gave also good pictures of them. In the 19th century examples of veterinary duplication monstrosities were published by I. Geoffroy Saint-Hilaire (1832-37), E. F. Gurlt (1832), W. Vrolik (1840) and C. Taruffi (1881); they proposed also concepts concerning the etiology. In the second volume of his famous handbook of teratology (1907), E. Schwalbe described many veterinary double monsters and discussed the theories of the genesis of congenital malformations. Various theories concerning the genesis of double monsters have been given since Aristotle (384-322 B.C.). ...

We prove that if K has nontrivial signature $\\sigma$, then the n-iterated Bing double of K is not concordant to any boundary link with boundary surfaces of genus less than $2^{n-1}\\sigma$. The same result holds with $\\sigma$ replaced by $2\\tau$, twice the Ozsvath-Szabo knot concordance invariant.

    The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6. These lymphomas, which occur in <10% of cases of diffuse large B-cell lymphoma, have been referred to as double-hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium. © 2017 by The American Society of Hematology.

  16. Double infarction in one cerebral hemisphere.

    1991-07-01

    Thirty-two patients whose first stroke was due to double infarct in one cerebral hemisphere were identified among 1,911 consecutive patients from the Lausanne Stroke Registry. The double infarct involved territories of the superficial middle cerebral artery, superficial posterior cerebral artery, lenticulostriate, anterior choroidal artery, or borderzone. The most common combination involved territories of the anterior middle cerebral artery plus the posterior middle cerebral artery. In the patients with the double infarct, the prevalence of potential cardiac sources of embolism (19%) was similar to that found in the registry in general, but the double infarct was closely associated with tight (greater than or equal to 90% of the lumen diameter) stenosis or occlusion (75%) of the internal carotid artery. The most common neurological picture mimicked large infarction in the middle cerebral artery territory, but nearly half of the patients with double infarct in one cerebral hemisphere had a specific clinical syndrome, which was not found in the 1,879 remaining patients from the registry, including hemianopia-hemiplegia (in 6), acute conduction aphasia-hemiparesis (in 2), and acute transcortical mixed aphasia (in 6), in relation to characteristic combinations of infarcts. These unique clinical and etiological correlates warrant the recognition of double infarct in one cerebral hemisphere from other acute ischemic strokes.

  17. THE EFFICIENCY OF TENNIS DOUBLES SCORING SYSTEMS

    Full Text Available In this paper a family of scoring systems for tennis doubles for testing the hypothesis that pair A is better than pair B versus the alternative hypothesis that pair B is better than A, is established. This family or benchmark of scoring systems can be used as a benchmark against which the efficiency of any doubles scoring system can be assessed. Thus, the formula for the efficiency of any doubles scoring system is derived. As in tennis singles, one scoring system based on the play-the-loser structure is shown to be more efficient than the benchmark systems. An expression for the relative efficiency of two doubles scoring systems is derived. Thus, the relative efficiency of the various scoring systems presently used in doubles can be assessed. The methods of this paper can be extended to a match between two teams of 2, 4, 8, …doubles pairs, so that it is possible to establish a measure for the relative efficiency of the various systems used for tennis contests between teams of players.

    The double patterning (DPT) process is foreseen by the industry to be the main solution for the 32 nm technology node and even beyond. Meanwhile process compatibility has to be maintained and the performance of overlay metrology has to improve. To achieve this for Image Based Overlay (IBO), usually the optics of overlay tools are improved. It was also demonstrated that these requirements are achievable with a Diffraction Based Overlay (DBO) technique named SCOLTM [1]. In addition, we believe that overlay measurements with respect to a reference grid are required to achieve the required overlay control [2]. This induces at least a three-fold increase in the number of measurements (2 for double patterned layers to the reference grid and 1 between the double patterned layers). The requirements of process compatibility, enhanced performance and large number of measurements make the choice of overlay metrology for DPT very challenging. In this work we use different flavors of the standard overlay metrology technique (IBO) as well as the new technique (SCOL) to address these three requirements. The compatibility of the corresponding overlay targets with double patterning processes (Litho-Etch-Litho-Etch (LELE); Litho-Freeze-Litho-Etch (LFLE), Spacer defined) is tested. The process impact on different target types is discussed (CD bias LELE, Contrast for LFLE). We compare the standard imaging overlay metrology with non-standard imaging techniques dedicated to double patterning processes (multilayer imaging targets allowing one overlay target instead of three, very small imaging targets). In addition to standard designs already discussed [1], we investigate SCOL target designs specific to double patterning processes. The feedback to the scanner is determined using the different techniques. The final overlay results obtained are compared accordingly. We conclude with the pros and cons of each technique and suggest the optimal metrology strategy for overlay control in double

  1. Double Engine for a Nebula

    Science.gov (United States)

    2009-08-01

    ESO has just released a stunning new image of a field of stars towards the constellation of Carina (the Keel). This striking view is ablaze with a flurry of stars of all colours and brightnesses, some of which are seen against a backdrop of clouds of dust and gas. One unusual star in the middle, HD 87643, has been extensively studied with several ESO telescopes, including the Very Large Telescope Interferometer (VLTI). Surrounded by a complex, extended nebula that is the result of previous violent ejections, the star has been shown to have a companion. Interactions in this double system, surrounded by a dusty disc, may be the engine fuelling the star's remarkable nebula. The new image, showing a very rich field of stars towards the Carina arm of the Milky Way, is centred on the star HD 87643, a member of the exotic class of B[e] stars [1]. It is part of a set of observations that provide astronomers with the best ever picture of a B[e] star. The image was obtained with the Wide Field Imager (WFI) attached to the MPG/ESO 2.2-metre telescope at the 2400-metre-high La Silla Observatory in Chile. The image shows beautifully the extended nebula of gas and dust that reflects the light from the star. The central star's wind appears to have shaped the nebula, leaving bright, ragged tendrils of gas and dust. A careful investigation of these features seems to indicate that there are regular ejections of matter from the star every 15 to 50 years. A team of astronomers, led by Florentin Millour, has studied the star HD 87643 in great detail, using several of ESO's telescopes. Apart from the WFI, the team also used ESO's Very Large Telescope (VLT) at Paranal. At the VLT, the astronomers used the NACO adaptive optics instrument, allowing them to obtain an image of the star free from the blurring effect of the atmosphere. To probe the object further, the team then obtained an image with the Very Large Telescope Interferometer (VLTI). The sheer range of this set of observations

    "Knowledge about the dynamics of the D double prime region is a key to unlock some fundamental mysteries of the Earth heat engine which governs a wide range of global geophysical processes from tectonics to geodynamo." This benign sentence makes complete sense to many geophysicists. But for many others, it makes sense all except the odd nomenclature "D double prime". One knows about the crust, upper and lower mantle, outer and inner core, but where is the D double prime region? What meaning does it try to convey? Where is D prime region, or D, or A, B, C regions for that matter, and are there higher-order primes? How does such an odd name come about anyway? D double prime, or more "simply" D", is a generic designation given to the thin shell, about 200 km thick, of the lowermost mantle just above the core-mantle boundary inside the Earth. Incidentally, whether D" is "simpler" than "D double prime" depends on whether you are pronouncing it or writing/typing it; and D" can be confusing to readers in distinguishing quotation marks (such as in the above sentences) and second derivatives, and to word processors in spelling check and indexing.

    We revisit the fundamental string (F1) solution in the doubled formalism. We show that the wave-like solution of double field theory (DFT) corresponding to the F1/pp-wave duality pair is more properly a solution of the DFT action coupled to a doubled sigma model action. The doubled string configuration which sources the pp-wave can be thought of as static gauge with the string oriented in a dual direction. We also discuss the DFT solution corresponding to a vibrating string, carrying both winding and momentum. We further show that the solution dual to the F1 in both time and space can be viewed as a "negative string" solution. Negative branes are closely connected to certain exotic string theories which involve unusual signatures for both spacetime and brane worldvolumes. In order to better understand this from the doubled point of view, we construct a variant of DFT suitable for describing theories in which the fundamental string has a Euclidean worldsheet, for which T-dualities appear to change the spacetim...

Highlights: Black-Right-Pointing-Pointer We synthesize layered double hydroxides from eggshells. Black-Right-Pointing-Pointer Eggshells are the mainly material in this method. Black-Right-Pointing-Pointer The additional alkaline solution is not required. - Abstract: Ca-Al and Ca-Fe layered double hydroxides (LDHs) were successfully synthesized from chicken eggshells by an ultrasonic wave assistant method. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR) techniques. XRD and TEM analyses showed that the 4Ca-Al LDHs were of high purity but other samples were not. The present study provides a simple, efficient and environmental friendly method to obtain LDHs from biowaste eggshells, in which additional alkaline solution is not required for synthesis. Moreover, eggshells provide all the requisite bivalent metal ions, which are needed to form layered double hydroxides.

  7. Double-difference adjoint seismic tomography

    Science.gov (United States)

    Yuan, Yanhua O.; Simons, Frederik J.; Tromp, Jeroen

    2016-09-01

    We introduce a `double-difference' method for the inversion for seismic wave speed structure based on adjoint tomography. Differences between seismic observations and model predictions at individual stations may arise from factors other than structural heterogeneity, such as errors in the assumed source-time function, inaccurate timings and systematic uncertainties. To alleviate the corresponding non-uniqueness in the inverse problem, we construct differential measurements between stations, thereby reducing the influence of the source signature and systematic errors. We minimize the discrepancy between observations and simulations in terms of the differential measurements made on station pairs. We show how to implement the double-difference concept in adjoint tomography, both theoretically and practically. We compare the sensitivities of absolute and differential measurements. The former provide absolute information on structure along the ray paths between stations and sources, whereas the latter explain relative (and thus higher resolution) structural variations in areas close to the stations. Whereas in conventional tomography a measurement made on a single earthquake-station pair provides very limited structural information, in double-difference tomography one earthquake can actually resolve significant details of the structure. The double-difference methodology can be incorporated into the usual adjoint tomography workflow by simply pairing up all conventional measurements; the computational cost of the necessary adjoint simulations is largely unaffected. Rather than adding to the computational burden, the inversion of double-difference measurements merely modifies the construction of the adjoint sources for data assimilation.

    Generation of high power double-scale pulses from a gain-guided double-clad fiber laser is experimentally demonstrated. By employing the Yb-doped 10/130 double-clad fiber as the gain medium, the laser realizes an output power of 5.1 W and pulse energy of 0.175 µJ at repetition rate of 29.14 MHz. To the best of our knowledge, this average output power is the highest among the reported double-scale pulse oscillators. The autocorrelation trace of pulses contains the short (98 fs) and long (29.5 ps) components, and the spectral bandwidth of the pulse is 27.3 nm. Such double-scale pulses are well suited for seeding the high power MOPA (master oscillator power amplifier) systems, nonlinear frequency conversion and optical coherence tomography.

  11. Double Planet Meets Triple Star

    Science.gov (United States)

    2002-08-01

    High-Resolution VLT Image of Pluto Event on July 20, 2002 A rare celestial phenomenon involving the distant planet Pluto has occurred twice within the past month. Seen from the Earth, this planet moved in front of two different stars on July 20 and August 21, respectively, providing observers at various observatories in South America and in the Pacific area with a long awaited and most welcome opportunity to learn more about the tenuous atmosphere of that cold planet. On the first date, a series of very sharp images of a small sky field with Pluto and the star was obtained with the NAOS-CONICA (NACO) adaptive optics (AO) camera mounted on the ESO VLT 8.2-m YEPUN telescope at the Paranal Observatory. With a diameter of about 2300 km, Pluto is about six times smaller than the Earth. Like our own planet, it possesses a relatively large moon, Charon , measuring 1200 km across and circling Pluto at a distance of about 19,600 km once every 6.4 days. In fact, because of the similarity of the two bodies, the Pluto-Charon system is often referred to as a double planet . At the current distance of nearly 4,500 million km from the Earth, Pluto's disk subtends a very small angle in the sky, 0.107 arcsec. It is therefore very seldom that Pluto - during its orbital motion - passes exactly in front of a comparatively bright star. Such events are known as "occultations" , and it is difficult to predict exactly when and where on the Earth's surface they are visible. Stellar occultations When Pluto moves in front of a star, it casts a "shadow" on the Earth's surface within which an observer cannot see the star, much like the Earth's Moon hides the Sun during a total solar eclipse. During the occultation event, Pluto's "shadow" also moves across the Earth's surface. The width of this shadow is equal to Pluto's diameter, i.e. about 2300 km. One such occultation event was observed in 1988, and two others were expected to occur in 2002, according to predictions published in 2000 by

  12. Particle acceleration and dynamics of double-double radio galaxies: theory versus observations

    2013-12-01

    In this paper, we show that a small sample of radio galaxies with evidence for multiple epochs of jet activity (so-called double-double radio galaxies) have the same electron injection spectral index in the two activity episodes, a result which might be considered surprising given the very different lobe dynamics expected in the first and second episode. We construct models for the dynamics of radio galaxies, with an emphasis on their episodic behaviour, and show that hotspot formation and confinement of lobes for the inner double of double-double radio galaxies are possible even without any thermal matter in the outer cocoon. We argue that (i) the observed similar injection spectral indices are due to similar jet powers in the two episodes, (ii) the `spectral index-radio power' correlation of a flux limited sample of radio galaxies is the primary one, and not the `spectral index-redshift correlation', (iii) jets are made of pair plasma and not electron-proton and (iv) the Lorentz factor of the spine of the jet should be ≳ 10 to explain the observations. Furthermore, we argue that the observations show that higher power radio galaxies do not have a higher jet bulk Lorentz factors, but instead simply have a higher number density of particles in the jet rest frame. A consequence of our models is that aligned double-double radio galaxies with very old ( ≳ 108 yr) outer doubles, or misaligned double-double radio galaxies, are statistically more likely to have dissimilar injection indices in two different episodes, as they will probably have different jet powers.

    We describe a muon track reconstruction algorithm for the reactor anti-neutrino experiment Double Chooz. The Double Chooz detector consists of two optically isolated volumes of liquid scintillator viewed by PMTs, and an Outer Veto above these made of crossed scintillator strips. Muons are reconstructed by their Outer Veto hit positions along with timing information from the other two detector volumes. All muons are fit under the hypothesis that they are through-going and ultrarelativistic. If the energy depositions suggest that the muon may have stopped, the reconstruction fits also for this hypothesis and chooses between the two via the relative goodness-of-fit. In the ideal case of a through-going muon intersecting the center of the detector, the resolution is ~40 mm in each transverse dimension. High quality muon reconstruction is an important tool for reducing the impact of the cosmogenic isotope background in Double Chooz.

    2010-04-01

    Full Text Available Hypernuclear Physics is currently attracting renewed attention. Thanks to the use of stored $ar{p}$ beams, copious production of double Λ hypernuclei is expected at the $ar{P}$anda experiment which will enable high precision γ–spectroscopy of such nuclei for the first time. In the present work we have studied the population of particle stable, excited states in double hypernuclei after the capture of a Ξ− within a statistical decay model. In order to check the feasibility of producing and performing γ–spectroscopy of double hypernuclei at $ar{P}$ANDA, an event generator based on these calculations has been implemented in the $ar{P}$ANDA simulation framework PANDAROOT.

    First measurement of double-hadron production in deep-inelastic scattering has been measured with the HERMES spectrometer at HERA using a 27.6 GeV positron beam with deuterium, nitrogen, krypton and xenon targets. The influence of the nuclear medium on the ratio of double-hadron to single-hadron yields has been investigated. Nuclear effects are clearly observed but with substantially smaller magnitude and reduced $A$-dependence compared to previously measured single-hadron multiplicity ratios. The data are in fair agreement with models based on partonic or pre-hadronic energy loss, while they seem to rule out a pure absorptive treatment of the final state interactions. Thus, the double-hadron ratio provides an additional tool for studying modifications of hadronization in nuclear matter.

  16. Innocuous Double Rounding of Basic Arithmetic Operations

    Directory of Open Access Journals (Sweden)

    Pierre Roux

    2014-11-01

    Full Text Available Double rounding occurs when a floating-point value is first rounded to an intermediate precision before being rounded to a final precision. The result of two such consecutive roundings can differ from the result obtained when directly rounding to the final precision. Double rounding practically happens, for instance, when implementing the IEEE754 binary32 format with an arithmetic unit performing operations only in the larger binary64 format, such as done in the PowerPC or x87 floating-point units. It belongs to the folklore in the floating-point arithmetic community that double rounding is innocuous for the basic arithmetic operations (addition, division, multiplication, and square root as soon as the final precision is about twice larger than the intermediate one. This paper adresses the formal proof of this fact considering underflow cases and its extension to radices other than two.

    Touched evidence is often submitted to forensic laboratories for DNA analysis. Classical stain recovery technique, involving one wet cotton swab, is commonly used for recovering the touched evidence. Double swab technique, using a wet cotton swab followed by a dry cotton swab, was compared with the classical technique for recovering the touched evidence. The wet cotton swabs and the dry cotton swabs were individually extracted. DNA extracts were quantified and amplified at 15 polymorphic loci. DNA recovered in some of the second dry swabs contained sufficient amount of DNA to yield a DNA profile. This study shows that the double swab technique improves the quality of the resulting DNA profiles. The double swab technique for recovering touched evidence at crime scenes is recommended.

  18. Black holes and the double copy

    Monteiro, Ricardo; White, Chris D

    2014-01-01

    Recently, a perturbative duality between gauge and gravity theories (the double copy) has been discovered, that is believed to hold to all loop orders. In this paper, we examine the relationship between classical solutions of non-Abelian gauge theory and gravity. We propose a general class of gauge theory solutions that double copy to gravity, namely those involving stationary Kerr-Schild metrics. The Schwarzschild and Kerr black holes (plus their higher-dimensional equivalents) emerge as special cases. We also discuss plane wave solutions. Furthermore, a recently examined double copy between the self-dual sectors of Yang-Mills theory and gravity can be reinterpreted using a momentum-space generalisation of the Kerr-Schild framework.

    While the discovery of non-zero neutrino masses is one of the most important accomplishments by physicists in the past century, it is still unknown how and in what form these masses arise. Lepton number-violating neutrinoless double beta decay is a natural consequence of Majorana neutrinos and many BSM theories, and many experimental efforts are involved in the search for these processes. Understanding how neutrinoless double beta decay would manifest in nuclear environments is key for understanding any observed signals. In these proceedings we present an overview of a set of one- and two-body matrix elements relevant for experimental searches for neutrinoless double beta decay, describe the role of lattice QCD calculations, and present preliminary lattice QCD results.

    This article introduces mixed double Hurwitz numbers, which interpolate combinatorially between the classical double Hurwitz numbers studied by Okounkov and the monotone double Hurwitz numbers introduced recently by Goulden, Guay-Paquet and Novak. Generalizing a result of Okounkov, we prove that a certain generating series for the mixed double Hurwitz numbers solves the 2-Toda hierarchy of partial differential equations. We also prove that the mixed double Hurwitz numbers are piecewise polynomial, thereby generalizing a result of Goulden, Jackson and Vakil.

    Astronomers have long tracked double stars in efforts to find those that are gravitationally-bound binaries and then to determine their orbits. Court reporter and amateur astronomer Shelburne Wesley Burnham (1838-1921) published a massive double star catalogue containing more than 13,000 systems in 1906. The next keeper of the double stars was Lick Observatory astronomer Robert Grant Aitken (1864-1951), who produced a much larger catalogue in 1932. Aitken maintained and expanded Burnham’s records of observations on handwritten file cards, eventually turning them over to Lick Observatory astrometrist Hamilton Moore Jeffers (1893-1976). Jeffers further expanded the collection and put all the observations on punched cards. With the aid of Frances M. "Rete" Greeby (1921-2002), he made two catalogues: an Index Catalogue with basic data about each star, and a complete catalogue of observations, with one observation per punched card. He enlisted Willem van den Bos of Johannesburg to add southern stars, and they published the Index Catalogue of Visual Double Stars, 1961.0. As Jeffers approached retirement he became greatly concerned about the disposition of the catalogues. He wanted to be replaced by another "double star man," but Lick Director Albert E. Whitford (1905-2002) had the new 120-inch reflector, the world’s second largest telescope, and he wanted to pursue modern astrophysics instead. Jeffers was vociferously opposed to turning over the card files to another institution, and especially against their coming under the control of Kaj Strand of the U.S. Naval Observatory. In the end the USNO got the files and has maintained the records ever since, first under Charles Worley (1935-1997), and, since 1997, under Brian Mason. Now called the Washington Double Star Catalog (WDS), it is completely online and currently contains more than 1,000,000 measures of more than 100,000 pairs.

  3. Higher Spin Double Field Theory : A Proposal

    2016-01-01

    We construct a double field theory of higher spin gravity. Employing "semi-covariant" differential geometry, we spell a functional in which each term is completely covariant with respect to $\\mathbf{O}(4,4)$ T-duality, doubled diffeomorphisms, $\\mathbf{Spin}(1,3)$ local Lorentz symmetry and, separately, $\\mathbf{HS}(4)$ higher spin gauge symmetry. We also propose a set of BPS-like conditions whose solutions automatically satisfy the full Euler-Lagrange equations. As such a solution, we derive a linear dilaton vacuum. With extra algebraic constraints further imposed, our BPS proposal reduces to the bosonic Vasiliev equations.

    The double loop network G(N; r, s) has N vertices and 2N directed edges. A natural question is how to choose r and s such that G(N; r, s) has diameter as short as possible for a given N. In 1993, Li, Xu and Zhang proposed a method of constructing double loop networks with the minimum diameter for the case of r=1.The method is developed to construct such networks that none of their minimum diameters can be reached at r=1.As a by-product, a flaw in an assertation by Esqu et al. is pointed out.

    In this paper we report a new method for double phase conjugation particularly suited to the tungsten bronze crystal strontium barium niobate. It has also been observed to produce conjugate waves in BaTiO(3) and BSKNN. This new arrangement is called the bridge conjugator because the two beams enter opposing [100] crystal faces and fan together to form a bridge without reflection off a crystal face. Our measurements indicate that the bridge conjugator is competitive with previously reported double phase conjugate mirrors in reflectivity, response time, ease of alignment, and fidelity.

    Easter, Robert Benjamin; Hitzer, Eckhard

    2017-01-01

    The Double Conformal Space-Time Algebra (DCSTA) is a high-dimensional 12D Geometric Algebra G 4,8that extends the concepts introduced with the Double Conformal / Darboux Cyclide Geometric Algebra (DCGA) G 8,2 with entities for Darboux cyclides (incl. parabolic and Dupin cyclides, general quadrics, and ring torus) in spacetime with a new boost operator. The base algebra in which spacetime geometry is modeled is the Space-Time Algebra (STA) G 1,3. Two Conformal Space-Time subalgebras (CSTA) G 2,4 provide spacetime entities for points, flats (incl. worldlines), and hyperbolics, and a complete set of versors for their spacetime transformations that includes rotation, translation, isotropic dilation, hyperbolic rotation (boost), planar reflection, and (pseudo)spherical inversion in rounds or hyperbolics. The DCSTA G 4,8 is a doubling product of two G 2,4 CSTA subalgebras that inherits doubled CSTA entities and versors from CSTA and adds new bivector entities for (pseudo)quadrics and Darboux (pseudo)cyclides in spacetime that are also transformed by the doubled versors. The "pseudo" surface entities are spacetime hyperbolics or other surface entities using the time axis as a pseudospatial dimension. The (pseudo)cyclides are the inversions of (pseudo)quadrics in rounds or hyperbolics. An operation for the directed non-uniform scaling (anisotropic dilation) of the bivector general quadric entities is defined using the boost operator and a spatial projection. DCSTA allows general quadric surfaces to be transformed in spacetime by the same complete set of doubled CSTA versor (i.e., DCSTA versor) operations that are also valid on the doubled CSTA point entity (i.e., DCSTA point) and the other doubled CSTA entities. The new DCSTA bivector entities are formed by extracting values from the DCSTA point entity using specifically defined inner product extraction operators. Quadric surface entities can be boosted into moving surfaces with constant velocities that display the length

    In the field of Double Beta Decay (DBD) searches, the use of high resolution detectors in which background can be actively discriminated is very appealing. Scintillating bolometers containing a Double Beta Decay emitter can largely fulfill this very interesting possibility. In this paper we present the latest results obtained with CdWO4 and CaMoO4 crystals. Moreover we report, for the first time, a very interesting feature of CaMoO4 bolometers: the possibility to discriminate beta-gamma events from those induced by alpha particles thanks to different thermal pulse shape.

In this paper, we propose a new technique for double patterning post decomposition conflict resolution. The algorithm is based on lines positions encoding followed by code pattern matching. Experimental results show that the usage of encoded patterns decreases the time needed for pattern matching and increases the matching accuracy. The overall manual problem solution time is reduced to about 1%.

    Surgically treated patients with arteriovenous malformations (AVMs) are considered cured when the postoperative angiogram proves complete resection. However, despite no residual nidus or early draining vein on postoperative angiogram, rare instances of AVM recurrence have been reported in adults. In this paper, the authors present a case of a 24-year-old woman with asymptomatic double recurrence of her cerebral AVM after angiographically proven complete resection. To the authors' knowledge, this patient represents the first case with double de novo asymptomatic recurrence of Spetzler-Martin grade I AVM. Also, she represents the first case with unique AVM criteria in each recurrence.

    We introduce a simple geometric model for a double-stranded and double-helical polymer. We study the statistical mechanics of such polymers using both analytical techniques and simulations. Our model has a single energy scale which determines both the bending and twisting rigidity of the polymer. The helix melts at a particular temperature T(c) below which the chain has a helical structure and above which this structure is disordered. Under extension we find that for small forces, the behavior is very similar to wormlike chain behavior but becomes very different at higher forces.

    We study the problem of locating a single facility on a real line based on the reports of self-interested agents, when agents have double-peaked preferences, with the peaks being on opposite sides of their locations. We observe that double-peaked preferences capture real-life scenarios and thus...... complement the well-studied notion of single-peaked preferences. We mainly focus on the case where peaks are equidistant from the agents’ locations and discuss how our results extend to more general settings. We show that most of the results for single-peaked preferences do not directly apply to this setting...

  16. Probabilistic double guarantee kidnapping detection in SLAM.

    Tian, Yang; Ma, Shugen

    2016-01-01

    For determining whether kidnapping has happened and which type of kidnapping it is while a robot performs autonomous tasks in an unknown environment, a double guarantee kidnapping detection (DGKD) method has been proposed. The good performance of DGKD in a relative small environment is shown. However, a limitation of DGKD is found in a large-scale environment by our recent work. In order to increase the adaptability of DGKD in a large-scale environment, an improved method called probabilistic double guarantee kidnapping detection is proposed in this paper to combine probability of features' positions and the robot's posture. Simulation results demonstrate the validity and accuracy of the proposed method.

  17. Detecting Double Beta Decays Using Nuclear Emulsions

    CERN Document Server

    2008-01-01

    Neutrino nature and absolute mass scale are major questions in particle physics which cannot be addressed by the present neutrino oscillation program. To answer these two questions, several neutrinoless double beta decay experiments are underway or planed for the near future. These experiments, mainly use bolometric techniques or gaseous counters coupled with scintillator detectors. The energy resolution is better in bolometric experiments but experiments coupling tracking with calorimetry have the advantage of observing the two electron tracks and remove many background sources. Here, we present a proposal of using nuclear emulsions to observe double beta decays. This technique has the advantage of precise tracking and vertexing even for low energy electrons.

    If any double star discoverer is in urgent need of photometry then it is Jonckheere. There are over 3000 Jonckheere objects listed in the WDS catalog and a good part of them have magnitudes which are obviously far too bright. This report covers the Jonckheere objects in the constellation Cancer. Only one image per object was taken as despite the risk of random effects even a single measurement is better than the currently usually given estimation, although the J-objects in this constellation seem with some exceptions better covered with observations as usual for Jonckheere doubles.

    The acoustic transmission of a closely spaced pair of patterned and perforated rigid plates is explored in air. The structure resembles an acoustic double fishnet design, with each plate modified such that the gap between them acts as an array of Helmholtz resonators. This allows the center frequency of the stop band to be reduced by a factor greater than 2 from the value obtained for the conventional acoustic double fishnet design. Experimental results accord well with the predictions of a finite element model.

    A double peak hydrograph features two peaks as a response to a unique rainfall pulse. The first peak occurs at the same time or shortly after the precipitation has started and it corresponds to a fast catchment response to precipitation. The delayed peak normally starts during the recession of the first peak, when the precipitation has already ceased. Double peak hydrographs may occur for various reasons. They can occur (i) in large catchments when lag times in tributary responses are large, (ii) in urban catchments where the first peak is often caused by direct surface runoff on impervious land cover, and the delayed peak to slower subsurface flow, and (iii) in non-urban catchments, where the first and the delayed discharge peaks are explained by different runoff mechanisms (e.g. overland flow, subsurface flow and/or deep groundwater flow) that have different response times. Here we focus on the third case, as a formal description of the different hydrological mechanisms explaining these complex hydrological dynamics across catchments with diverse physiographic characteristics is still needed. Based on a review of studies documenting double peak events we have established a formal classification of catchments presenting double peak events based on their regolith structure (geological substratum and/or its weathered products). We describe the different hydrological mechanisms that trigger these complex hydrological dynamics across each catchment type. We then use hydrometric time series of precipitation, runoff, soil moisture and groundwater levels collected in the Weierbach (0.46 km2) headwater catchment (Luxembourg) to better understand double peak hydrograph generation. Specifically, we aim to find out (1) if the generation of a double peak hydrograph is a threshold process, (2) if the hysteretic relationships between storage and discharge are consistent during single and double peak hydrographs, and (3) if different functional landscape units (the hillslopes

    A double-SQUID qubit (flash-qubit) allows the manipulation of quantum states by very short pulses of magnetic flux, without using microwaves. It consists of an rf-SQUID with a dc-SQUID replacing the single Josephson junction. The energy potential profile is controllable by dc bias fluxes threading the two loops. The initial qubit state in a double well is prepared by applying a dc flux pulse to one loop, thereby tilting the double well so that only one of the two states remains stable. To manipulate the state of the qubit a dc flux pulse is applied to the other loop to change the potential into a single well, where coherent Larmor oscillations between the two lowest eigenstates take place. Reading out the state is once again performed in the double well situation, where our readout dc-SQUID is able to discriminate between the two computational states due to their flux difference. We hope to present measurements done on a new sample, fabricated using shadow evaporation of aluminium and silicon nitride as the dielectric.

  7. [Euthanasia and the doctrine of double effect].

    Science.gov (United States)

    Klein, Martin

    2005-01-01

    Direct active euthanasia is prohibited in most countries while passive and indirect is not. However, many arguments against the legalization of voluntary active euthanasia are flawed. Ethical differences between active and passive or indirect euthanasia are difficult to maintain especially when the passivity of the actor causes death. The crucial point is not activity or passivity but respect for the autonomy of individual human beings. In particular there appears to be little ethical difference between active and indirect euthanasia. Indirect euthanasia has often been justified by the principle of double effect, which traces back to Thomas Aquinas. But resorting to this rule contains a logical fallacy. The principle of double effect does not allow foreseen and unwanted adverse effects of an action to occur when they are avoidable. In terminal sedation, an example for indirect euthanasia, hypoxemia and dehydration can easily be prevented by respirator therapy and fluid administration. Therefore the rule of double effect is not applicable. Indirect and direct active euthanasia cannot be ethically distinguished by resorting to the principle of double effect.

    Epitaxial III-V semiconductor heterostructures are key components in modern microelectronics, electro-optics, and optoelectronics. With superior semiconducting properties, halide perovskite materials are rising as promising candidates for coherent heterostructure devices. In this report, spinodal decomposition is proposed and experimentally implemented to produce epitaxial double heterostructures in halide perovskite system. Pristine epitaxial mixed halide perovskites rods and films were synthesized via van der Waals epitaxy by chemical vapor deposition method. At room temperature, photon was applied as a knob to regulate the kinetics of spinodal decomposition and classic coarsening. By this approach, halide perovskite double heterostructures were created carrying epitaxial interfaces and outstanding optical properties. Reduced Fröhlich electron-phonon coupling was discovered in coherent halide double heterostructure, which is hypothetically attributed to the classic phonon confinement effect widely existing in III-V double heterostructures. As a proof-of-concept, our results suggest that halide perovskite-based epitaxial heterostructures may be promising for high-performance and low-cost optoelectronics, electro-optics, and microelectronics. Thus, ultimately, for practical device applications, it may be worthy to pursue these heterostructures via conventional vapor phase epitaxy approaches widely practised in III-V field.

    Double filtration plasmapheresis, one kind of fractionation plasmapheresis, was developed from membrane type plasmapheresis to remove only the pathogen and return the normal protein back to the patient. We started our automated double filtration plasmapheresis since December 1993. There were 13 patients who received one hundred treatments totally during one year period. And they are myasthenia gravis (8 patients); acute inflammatory demyelinating polyneuropathy (1 patient), multiple myeloma (1 patient); acquired factor VIII inhibitor (1 patient); autoimmune hemolytic anemia (1 patient); systemic lupus erythematous (1 patient). Technically double filtration plasmapheresis is easy to perform and time-saving. It also makes necessity of replacement fluid less frequent. Incidence of complication is rare, and this includes hypotension 2%, palpitation 1%, headache 1%, hemolysis 4%, air emboli 1%, high secondary pressure 2%, and no motality during our treatment. Clinical response is documented in cases of myasthenia gravis; acute inflammatory demyelinating polyneuropathy and acquired factor VIII inhibitor in our study. In conclusion, double filtration plasmapheresis is a time-saving, convenient, and safe therapeutic modality with rare complication. Because its effectiveness on limited kinds of diseases and costs relatively high price, thus plasmapheresis should be used in selected cases and treat aggressively if indicated.

    Double-outlet right ventricle is a form of ventriculoarterial connection. The definition formulated by the International Society for Nomenclature of Paediatric and Congenital Heart Disease is based on hearts with both arterial trunks supported in their greater part by a morphologically right ventricle. Bilateral infundibula and ventricular septal defects are highly debated criteria. This study examines the anatomic controversies surrounding double-outlet right ventricle. We show that hearts with double-outlet right ventricle can have atrioventricular-to-arterial valvular continuity. We emphasize the difference between the interventricular communication and the zone of deficient ventricular septation. The hearts examined were from the University of Florida in Gainesville; Johns Hopkins All Children's Hospital, St Petersburg, Fla; and Lurie Children's Hospital, Chicago, Ill. Each specimen had at least 75% of both arterial roots supported by the morphologically right ventricle, with a total of 100 hearts examined. The morphologic method was used to assess anatomic features, including arterial-atrioventricular valvular continuity, subarterial infundibular musculature, and the location of the hole between the ventricles. Most hearts had fibrous continuity between one of the arterial valves and an atrioventricular valve, with bilateral infundibula in 23%, and intact ventricular septum in 5%. Bilateral infundibula are not a defining feature of double-outlet right ventricle, representing only 23% of the specimens in our sample. The interventricular communication can have a posteroinferior muscular rim or extend to become perimembranous (58%). Double-outlet right ventricle can exist with an intact ventricular septum.

    While double pituitary adenomas have been found in approximately 1% of autopsy pituitaries, those in surgically resected material have been only rarely reported. We report herein 6 cases of double pituitary adenomas, which consisted of two histologically and/or immunohistochemically different areas among approximately 450 surgical specimens. Five out of 6 patients were men and the age was ranged between 18 and 61 years old. All these 6 patients presented acromegaly or acrogigantism and hyperprolactinemia was noted in 3 patients. In 2 patients (cases 1 and 2) the two adenomas belonged to different adenoma groups (GH-PRL-TSH group and FSH/LH group), while in the remaining 4 patients (cases 3-6) the two adenomas belonged to the same group (GH-PRL-TSH group). Thus, in all patients at least one of the two adenomas was GH-producing adenoma. Reasons for a high incidence of GH-producing adenomas in surgically resected double pituitary adenomas may include the presence of a variety of histologic subtypes among GH-producing adenomas and the advantage of cytokeratin immunostaining to distinguish these subtypes. In regard to pathogenesis of double pituitary adenomas, adenomas in cases 1 and 2 may be of multicentric occurrence, while those in cases 3-6 may occur through different clonal proliferation within originally one adenoma, resulting in diverse phenotypic expressions. Since there were patients with familial MEN 1 (case 2) and familial pituitary adenoma unrelated MEN 1 (case 3), genetic background should be also considered. Double pituitary adenomas in surgically resected material may not be so infrequent. Further molecular analysis will provide new insights into understanding the pathogenesis of pituitary adenomas and their mechanisms of multidirectional phenotypic diffrentiation.

    Full Text Available Uterine anomalies involving a double uterus, double cervix, also known as didelphys uterus, and complete septate vagina are rarely seen and have an associated fertility problem. However, artificial reproductive technology with embryo transfers can help solve this fertility challenge. Conception in the uterus in just one side is commonly seen for embryos, which are always transferred through the usually used (dilated vagina. We here present a patient with the above uterine anomaly who conceived with the aid of in vitro fertilization and embryo transfer to both uterine cavities under general anesthesia, which resulted in successful double singleton pregnancies with one fetus in each uterus. With intensive prenatal care, the pregnancy course for each fetus was rather uneventful. Although both fetuses were in cephalic presentation, cesarean section was performed at the 39th week of gestation with good outcomes in order to preclude anticipated difficulties if the baby had been delivered through the rarely dilated vagina. However, order of birth between the two fetuses was a crucial decision during the operation.

  17. Observations of double discontinuities in the magnetotail

    Science.gov (United States)

    Whang, Y. C.; Fairfield, D.; Smith, E. J.; Lepping, R. P.; Kokubun, S.; Saito, Y.

    Observations of slow shocks in the Earth's magnetotail at the plasma sheet-lobe boundaries have been well documented. We restudy the magnetic field data of two slow shocks: one was observed from Geotail on January 17, 1994 at XGSE = -92 RE, and another was observed from ISEE-3 on February 2, 1983 at XGSE = -220 RE. In both cases, the slow shock layer was followed by an adjoining rotational discontinuity layer on the postshock side. Compound structures each composed of a slow shock layer and an adjoining rotational discontinuity layer have been recently observed in interplanetary space from Wind, Geotail and Imp-8. Because the two successive discontinuities are very close to each other, the compound structure looks like a new kind of MHD discontinuity. It may be called a double discontinuity. Since double discontinuities exist not only in interplanetary space but also in the magnetotail region, they could be a general MHD structure in space plasma.

  18. Double Valve Replacement for Lupus Valvulitis

    Ferraris, Victor A.; Hawksley, Vaughn C.; Rabinowitz, Max; Coyne, Carolyn M.; Sullivan, Thomas J.; Sprague, Merle S.

    1990-01-01

    Hemodynamically significant lupus valvulitis, requiring valve replacement, is rare: 21 cases have been reported so far in the literature, and only 2 of these have involved double valve replacement. We describe an additional case of double valve replacement in a patient with systemic lupus erythematosus. The histopathologic and clinical features of this case suggest that valvular involvement resulted from both acute and chronic disease processes. Medical success in the treatment of systemic lupus erythematosus, especially that achieved through prolonged or high-dose steroid therapy, may cause chronic valvular disease to become a more common surgical problem. A review of the literature supports this contention. (Texas Heart Institute Journal 1990;17:56-60) Images PMID:15227191

    The tunneling of optical and acoustic phonons at normal incidence on a double-barrier is studied in this paper. Transmission coefficients and resonance conditions are derived theoretically under the assumption that the long-wavelength approximation is valid. It is shown that the behavior of the transmission coefficients for the symmetric double barrier has a Lorentzian form close to resonant frequencies and that Breit–Wigner's formula have a general validity in one-dimensional phonon tunneling. Authors also study the so-called generalized Hartman effect in the tunneling of long-wavelength phonons and show that this effect is a numerical artifact resulting from taking the opaque limit before exploring the variation with a finite barrier width. This study could be useful for the design of acoustic devices.

  20. Recursive double-size fixed precision arithmetic

    2011-01-01

    This work is a part of the SHIVA (Secured Hardware Immune Versatile Architecture) project whose purpose is to provide a programmable and reconfigurable hardware module with high level of security. We propose a recursive double-size fixed precision arithmetic called RecInt. Our work can be split in two parts. First we developped a C++ software library with performances comparable to GMP ones. Secondly our simple representation of the integers allows an implementation on FPGA. Our idea is to consider sizes that are a power of 2 and to apply doubling techniques to implement them efficiently: we design a recursive data structure where integers of size 2^k, for k>k0 can be stored as two integers of size 2^{k-1}. Obviously for k<=k0 we use machine arithmetic instead (k0 depending on the architecture).

  1. Double-difference adjoint seismic tomography

    CERN Document Server

    Yuan, Yanhua O; Tromp, Jeroen

    2016-01-01

    We introduce a `double-difference' method for the inversion for seismic wavespeed structure based on adjoint tomography. Differences between seismic observations and model predictions at individual stations may arise from factors other than structural heterogeneity, such as errors in the assumed source-time function, inaccurate timings, and systematic uncertainties. To alleviate the corresponding nonuniqueness in the inverse problem, we construct differential measurements between stations, thereby reducing the influence of the source signature and systematic errors. We minimize the discrepancy between observations and simulations in terms of the differential measurements made on station pairs. We show how to implement the double-difference concept in adjoint tomography, both theoretically and in practice. We compare the sensitivities of absolute and differential measurements. The former provide absolute information on structure along the ray paths between stations and sources, whereas the latter explain relat...

    Full Text Available We show that it is possible to construct a well-defined effective field theory incorporating string winding modes without using strong constraint in double field theory. We show that X-ray (Radon transform on a torus is well-suited for describing weakly constrained double fields, and any weakly constrained fields are represented as a sum of strongly constrained fields. Using inverse X-ray transform we define a novel binary operation which is compatible with the level matching constraint. Based on this formalism, we construct a consistent gauge transform and gauge invariant action without using strong constraint. We then discuss the relation of our result to the closed string field theory. Our construction suggests that there exists an effective field theory description for massless sector of closed string field theory on a torus in an associative truncation.

    2010-01-01

    Ferromagnetic microwires are investigated as fundamental components to generate metamaterials with double negative parameters. Electric and magnetic responses are, respectively, based on the finite conductivity and ferromagnetic resonance of the wires that in turn depend on their chemical composition. Tuning properties of samples are investigated in terms of the composition of the alloy and the applied magnetic field. The samples are measured and simulated in a waveguide environment for a large microwave frequency range. Numerical modeling supports the experimental results and helps to understand the physics involved in the transmission phenomena. Radius and conductivity of the wires are pointed out as the most critical parameters to generate a double negative response in terms of permittivity and permeability.

    The double-acquisition scheme for efficient data collection of hypercomplex data (the States method) of a two-dimensional experiment is adopted to magic-angle hopping (MAH) and magic-angle turning (MAT) experiments, which are powerful methods to measure the principal values of the chemical shift anisotropy (CSA) in a powder sample. It is shown that the double acquisition MAT (DAMAT) sequence realizes the S/N ratio comparable to or better than those of other variants of the MAH/MAT sequences. In addition, we show that DAMAT has preferable features that there are no spinning sidebands in the indirect dimension, and no spectral shearing is necessary. Copyright © 2016 Elsevier Inc.

    Full Text Available Chromosomal abnormalities are seen in nearly 1% of live born infants. We report a 5-year-old boy with the clinical features of Down syndrome, which is the most common human aneuploidy. Cytogenetic analysis showed a mosaicism for a double aneuploidy, Down syndrome and XYY. The karyotype was 47, XY,+21[19]/48, XYY,+21[6]. ish XYY (DXZ1 × 1, DYZ1 × 2. Mosaic double aneuploidies are very rare and features of only one of the aneuploidies may predominate in childhood. Cytogenetic analysis is recommended even if the typical features of a recognized aneuploidy are present so that any associated abnormality may be detected. This will enable early intervention to provide the adequate supportive care and management.

  8. Claus recycle with double combustion process

    2004-12-15

    A new modification is developed on conventional Claus process to increase the overall sulfur recovery as well as to decrease the costs. The modification combines both oxygen enrichment and recycling. The process is simulated and studied for various N{sub 2}/O{sub 2} ratios with and without using SURE double combustion technique. The predictions show that using pure oxygen in combustion, condensing water vapor in a condenser following the first sulfur condenser and recycling the effluent gas to combine it with fresh acid gas feed leads to large savings in the production cost and to a clean environment. However, it leads to a high adiabatic flame temperature which exceeds the maximum allowable temperature of the furnace material of construction as well as its refractory. To avoid these effects, it is necessary to use SURE double combustion technique. The oxygen flow rate to the first combustion stage should not exceed 78% O{sub 2}.

  11. Cascade of period doublings of tori

    Science.gov (United States)

    Arneodo, A.; Coullet, P. H.; Spiegel, E. A.

    1983-02-01

    A three-dimensional map is proposed to model the effects of periodic forcing on a system displaying a transition to chaos through a cascade of period-doubling bifurcations. The study outlined here raises the problem of the existence and bifurcation of invariant tori. A principal feature of the simulations of both the differential equations and the discrete dynamical systems is that it is possible to disrupt period-doubling sequences (and inverse sequences as well) by periodic external forcing. Even though the way in which this abortion works is not understood, the mechanism is thought to be associated with the destruction of tori (Aronson et al., 1982) when the system is on the verge of bifurcation. The simulations therefore suggest that in moving farther along the cascade, the tori become more fragile. It is suspected that for arbitrarily weak driving, the cascade will eventually be disrupted after the cascade has proceeded through a sufficient number of steps.

We show in the limit of slow charging that a combined Poisson-Nernst-Planck and heat equation, first studied by d'Entremont and Pilon [J. Power Sources 246, 887 (2014)JPSODZ0378-775310.1016/j.jpowsour.2013.08.024], recovers the temperature changes as predicted by the thermodynamic identity of Janssen et al. [Phys. Rev. Lett. 113, 268501 (2014)PRLTAO0031-900710.1103/PhysRevLett.113.268501], and disagrees with the approximative model of Schiffer et al. [J. Power Sources 160, 765 (2006)JPSODZ0378-775310.1016/j.jpowsour.2005.12.070] that predominates the literature. The thermal response to the adiabatic charging of supercapacitors contains information on electric double layer formation that has remained largely unexplored.

  14. Double papilla flap technique for dual purpose

    Full Text Available Marginal tissue recession exposes the anatomic root on the teeth, which gives rise to -common patient complaints. It is associated with sensitivity, tissue irritation, cervical abrasions, and esthetic concerns. Various types of soft tissue grafts may be performed when recession is deep and marginal tissue health cannot be maintained. Double papilla flap is an alternative technique to cover isolated recessions and correct gingival defects in areas of insufficient attached gingiva, not suitable for a lateral sliding flap. This technique offers the advantages of dual blood supply and denudation of interdental bone only, which is less susceptible to permanent damage after surgical exposure. It also offers the advantage of quicker healing in the donor site and reduces the risk of facial bone height loss. This case report presents the advantages of double papilla flap in enhancing esthetic and functional outcome of the patient.

  15. Cosmic Topology of Double Action Manifolds

    The cosmic microwave background (CMB) anisotropies in spherical 3-spaces with a non-trivial topology are studied. This paper discusses the special class of the so-called double action manifolds, which are for the first time analysed with respect to their CMB anisotropies. The CMB anisotropies are computed for all double action manifolds generated by a dihedral and a cyclic group with a group order of up to 180 leading to 33 different topologies. Several spaces are found which show a suppression of the CMB anisotropies on large angular distances as it is found on the real CMB sky. It turns out that these spaces possess fundamental cells defined as Voronoi domains which are close to highly symmetric polyhedra like Platonic or Archimedean ones.

    Double-hit lymphomas (DHLs) characterize a unique subset of B-cell non-Hodgkin lymphomas. DHL typically presents in older adults with high-risk clinical features. This entity carries a significantly inferior prognosis compared with typical cases of diffuse large B-cell lymphoma; however, emerging literature can identify discrete clinical features within DHL that are associated with a favorable prognosis. Emerging literature is also demonstrating that intensive upfront treatment strategies may improve outcome. Diagnosis, prognostication, and management of DHL are reviewed, as well as potential future directions incorporating novel biologically targeted therapies. Finally, double-expressing lymphomas (DELs) will be discussed and contrasted with DHL. Copyright © 2016 Elsevier Inc. All rights reserved.

    2016-01-01

    Young's classic double-slit experiment demonstrates the reality of interference when waves and particles travel simultaneously along two different spatial paths. Here, we propose a double-slit experiment in momentum space. We show that elastic scattering of vortex electrons proceeds via two paths in momentum space, which are well localized and well separated from each other. For such vortex beams, the (plane-wave) amplitudes along the two paths acquire adjustable phase shifts and produce interference fringes in the final angular distribution. We argue that this experiment can be realized with the present day technology. We show that it gives experimental access to the Coulomb phase, a quantity which plays an important role in all charged particle scattering but which usual scattering experiments are insensitive to.

  18. Amplitude determinant coupled cluster with pairwise doubles

    CERN Document Server

    Zhao, Luning

    2016-01-01

    Recently developed pair coupled cluster doubles (pCCD) theory successfully reproduces doubly occupied configuration interaction (DOCI) with mean field cost. However, the projective nature of pCCD makes the method non-variational and thus hard to improve systematically. As a variational alternative, we explore the idea of coupled-cluster-like expansions based on amplitude determinants and develop a specific theory similar to pCCD based on determinants of pairwise doubles. The new ansatz admits a variational treatment through Monte Carlo methods while remaining size-consistent and, crucially, polynomial cost. In the dissociations of LiH, HF, H2O and N2, the method performs very similarly to pCCD and DOCI, suggesting that coupled-cluster-like ansatzes and variational evaluation may not be mutually exclusive.

    Differential cross sections have been measured for pion-induced double-charge-exchange (DCX) reactions leading to double-isobaric-analog states (DIAS) and low-lying nonanalog states in the residual nuclei. A description of the experimental details and data analysis is presented. The experimentally observed systematics of reactions leading to DIAS, to nonanalog ground states, and to low-lying 2 states are described. Lowest-order optical-model calculations of DIAS DCX are compared to the data. Efforts to understand the anomalies by invoking additional reaction-mechanism amplitudes and a higher-order optical potential are described. Calculations of nonanalog DCX reactions leading to J/sup / = 0 states were performed within a distorted-wave impulse-approximation framework. The sensitivities of these calculations to input parameters are discussed. 58 refs., 41 figs., 16 tabs.

    2006-12-01

    We consider double-diffusive convection between two parallel plates and compute bounds on the flux of the unstably stratified species using the background method. The bound on the heat flux for Rayleigh Bénard convection also serves as a bound on the double-diffusive problem (with the thermal Rayleigh number equal to that of the unstably stratified component). In order to incorporate a dependence of the bound on the stably stratified component, an additional constraint must be included, like that used by Joseph (Stability of Fluid Motion, 1976, Springer) to improve the energy stability analysis of this system. Our bound extends Joseph's result beyond his energy stability boundary. At large Rayleigh number, the bound is found to behave like R_T(1/2) for fixed ratio R_S/R_T, where R_T and R_S are the Rayleigh numbers of the unstably and stably stratified components, respectively.

    2010-01-01

    MP3 is the most popular audio format nowadays in our daily life, for example music downloaded from the Internet and file saved in the digital recorder are often in MP3 format. However, low bitrate MP3s are often transcoded to high bitrate since high bitrate ones are of high commercial value. Also audio recording in digital recorder can be doctored easily by pervasive audio editing software. This paper presents two methods for the detection of double MP3 compression. The methods are essential for finding out fake-quality MP3 and audio forensics. The proposed methods use support vector machine classifiers with feature vectors formed by the distributions of the first digits of the quantized MDCT (modified discrete cosine transform) coefficients. Extensive experiments demonstrate the effectiveness of the proposed methods. To the best of our knowledge, this piece of work is the first one to detect double compression of audio signal.

    Full Text Available Introduction. Xanthogranulomatous pyelonephritis (XGP is a type of chronic renal inflammation that usually occurs in immunocompromised middle-aged women with chronic urinary tract infection or ureteral obstruction induced by the formation of ureteral stones. XGP with an incomplete double ureter is extremely rare. Case Presentation. A 76-year-old woman was referred to our department to undergo further examination for a left renal tumor that was detected by ultrasonography. Dynamic contrast computed tomography (CT revealed an enhanced tumor in the upper renal parenchyma. Laparoscopic radical nephrectomy was performed based on a preoperative diagnosis of renal cell carcinoma. Histological sections showed the aggregation of foam cells; thus, XGP was diagnosed. Conclusion. We herein report a rare case of XGP in the upper pole of the kidney, which might have been associated with an incomplete double ureter.

    Full Text Available Abstract To our knowledge, this is the first case of synovial osteochondromatosis in a patient presenting with a double patella-like condition. The true duplication of the patella, which is called double patella, is extremely rare. In our case, the operative and histopathological findings showed that the double patella-like condition was secondarily induced by synovial osteochondromatosis. Synovial osteochondromatosis should be considered as a differential diagnosis for congenital double patella.

    We present a new detection scheme for rejecting backgrounds in neutrino less double beta decay experiments. It relies on the detection of Cherenkov light emitted by electrons in the MeV region. The momentum threshold is tuned to reach a good discrimination between background and good events. We consider many detector concepts and a range of target materials. The most promising is a high-pressure 136Xe emitter for which the required energy threshold is easily adjusted. Combination of this conc...

  19. Double charge exchange at high impact energies

    Science.gov (United States)

    Belkić, Dževad

    1994-03-01

    In fast ion-atom collisions, double ionization always dominates the two-electron transfer. For this reason, an adequate description of double charge exchange requires proper inclusion of intermediate ionization channels. This is even more important in two- than in one-electron transitions. First-order Born-type perturbation theories ignore throughout these electronic continuum intermediate states and hence provide utterly unreliable high energy cross sections for two-electron capture processes. Therefore, it is essential to use second- and higher-order theories, which include the intermediate ionization continua of the two electrons in an approximate manner. In the present paper, a new second-order theory called the Born distorted wave (BDW) approximation is introduced and implemented in the case of symmetric resonant double electron capture from the ground state of helium by fast alpha particles. A genuine four-body formalism is adopted, in contrast to the conventional independent particle model of atomic scattering theory. The obtained results for the total cross sections are compared with the available experimental data, and satisfactory agreement is recorded. As the incident energy increases, a dramatic improvement is obtained in going from the CB1 to the BDW approximation, since the latter closely follows the measurement, whereas the former overestimates the observed total cross sections by two orders of magnitude. This strongly indicates that the role of continuum intermediate states is decisive, even at those incident energies for which the Thomas double scattering effects are not important. This is in sharp contrast to the case of one-electron transfer atomic reactions.

    In 1962, James Watson, Francis Crick and Maurice Wilkins received the Nobel prize for the discovery of the structure of DNA. Notably absent from the podium was Rosalind Franklin, whose X-ray photographs of DNA contributed directly to the discovery of the double helix. Franklin's premature death, combined with misogynist treatment by the male scientific establishment, cast her as a feminist icon. This myth overshadowed her intellectual strength and independence both as a scientist and as an individual.

    Full Text Available Ahmed Abd El Alim MohamedOphthalmology department, Ain Shams University, Cairo, EgyptObjective: This study sought to evaluate the result of pars plana vitrectomy in patients with gunshot wounds involving double perforation.Methods: This was a retrospective, noncomparative, interventional case series.Results: Eighteen patients (18 eyes with double-perforation gunshot injuries were treated from February 2010 to March 2012. The group included 16 men (88% and two women (11%; the mean age was 24 (15–33 years. In each case, vitrectomy was scheduled 1–6 weeks after repair of the entrance site. Associated retinal detachments were observed in two eyes (11%, retinal incarceration was observed surrounding the exit site in three eyes (16%, and retention of an intraocular foreign body was observed in two cases. After a follow-up period of 8 ± 2 months, two eyes (11% had achieved visual acuity (VA of 0.5, nine eyes (50% had achieved VA between 0.5 and 0.1, and seven eyes (38% had achieved VA between 0.1 and hand movement. The main reasons for functional failure (VA 0.1 to hand movement were macular dragging (due to fibrosis at the exit site near the macula in seven cases (38%, submacular hemorrhage in four cases (22%, and epimacular fibrosis in five cases (27%. All cases developed postoperative exotropia. One case (5% developed postoperative hemorrhage. No cases exhibited signs of postoperative redetachment.Conclusion: The outcome of pars plana vitrectomy in cases with double perforations is variable. Factors including the surgeon's skill level, the time to surgery, and the efficacy of the intraocular tamponade affect the postoperative outcome.Keywords: pars plana vitrectomy, gunshot injury, double perforation

    A search for various double electron capture modes of $^{74}$Se has been performed using an ultralow background Ge-detector in the Felsenkeller laboratory, Germany. Especially for the potentially resonant transition into the 1204.2 keV excited state of $^{74}$Ge a lower half-life limit of $0.70\\cdot 10^{19}$ yr (90% credibility) has been obtained. Serious concerns are raised about the validity of obtained $^{74}$Se limits in some recent publications.

    Considering the coherent nonlinear dynamics in double square well potential we find the example of coexistence of Josephson oscillations with a self-trapping regime. This macroscopic bistability is explained by proving analytically the simultaneous existence of symmetric, antisymmetric and asymmetric stationary solutions of the associated Gross-Pitaevskii equation. The effect is illustrated and confirmed by numerical simulations. This property allows to make suggestions on possible experiments using Bose-Einstein condensates in engineered optical lattices or weakly coupled optical waveguide arrays.

    Layered double hydroxide was investigated as cordycepin delivery nanocarrier for the first time in this study. Negatively charged biomolecule-cordycepin was intercalated in the gallery spaces of [Mg-Al-NO3], which was confirmed by the results of X-ray diffraction and electrophoretic mobility. Cell experiment suggested that the new bio-LDH nanohybrid could prevent cordycepin decomposition by adenosine deaminase. This new formulation could possibly be used as a novel form cordycepin intravenous injection.

    It is a multi-phase-catalyzed reaction to produce calcium phenylpyruvate by double carbonylation of benzylchloride. Based on the analysis of the reaction mechanism, a kinetic model of the carbonylation reaction was obtained. The model was verified through experiments in which the diffusion effect was neglected with the appropriate operation manner. But it is inevitable that the carbonylation process is controlled by diffusion as the autoclave scaling up.

    The physics of swinging a tennis racquet is examined by modeling the forearm and the racquet as a double pendulum. We consider differences between a forehand and a serve, and show how they differ from the swing of a bat and a golf club. It is also shown that the swing speed of a racquet, like that of a bat or a club, depends primarily on its moment of inertia rather than on its mass.

    We show how the double parton distributions may be obtained consistently from the many-body light-cone wave functions. We illustrate the method on the example of the pion with two Fock components. The procedure, by construction, satisfies the Gaunt-Stirling sum rules. The resulting single parton distributions of valence quarks and gluons are consistent with a phenomenological parametrization at a low scale.

    Mesiodens is the most commonly erupting supernumerary in the midline between two maxillary central incisors. Mesiodentes is a rare condition when mesiodens erupt in multiples, which may present as either labial or palatal to permanent central incisors. We report a rare case of double mesiodentes (non-syndromic mesiodentes) with floret like appearance. The presence of mesiodens has functional and esthetic implications. Careful radiographic evaluation should be done to prevent complications during their extraction.

  16. Doubles of Quasi-Quantum Groups

    Hausser, F; Hausser, Frank; Nill, Florian

    1999-01-01

    Drinfeld showed that any finite dimensional Hopf algebra \\G extends to a quasitriangular Hopf algebra \\D(\\G), the quantum double of \\G. Based on the construction of a so--called diagonal crossed product developed by the authors, we generalize this result to the case of quasi--Hopf algebras \\G. As for ordinary Hopf algebras, as a vector space the ``quasi--quantum double'' \\D(\\G) is isomorphic to the tensor product of \\G and its dual \\dG. We give explicit formulas for the product, the coproduct, the R--matrix and the antipode on quasi--Hopf algebra. In particular \\D(\\G) becomes an associative algebra containing \\G as a quasi--Hopf subalgebra. On the other hand, \\dG øtimes 1 is not a subalgebra of \\D(\\G) unless the coproduct on \\G is strictly coassociative. It is shown that the category of finite dimensional representations of \\D(\\G) coincides with what has been called the double category of \\G--modules by S. Majid [M2]. Thus our construction gives a concrete realization of Majid's abstract definition of quasi-...

    We present a new detection scheme for rejecting backgrounds in neutrino-less double beta decay experiments. It relies on the detection of Cherenkov light emitted by electrons in the MeV region. The momentum threshold is tuned to reach a good discrimination between background and good events. We consider many detector concepts and a range of target materials. The most promising is the high-pressure 136Xe emitter where the required energy threshold is easily adjusted. Combination of this concept and a high pressure Time Projection Chamber could provide an optimal solution. A simple and low cost effective solution is the use of the Spherical Proportional Counter that provides, using a single read-out channel, two delayed signals from ionization and Cherenkov light. In solid-state double beta decay emitters, because of its higher density, the considered process is out of energy range. An escape will be the fabrication of double decay emitters having lower density by using for instance the aerogel technique. It is surprising that a technology used for particle identification in high-energy physics becomes a powerful tool for rejecting backgrounds in such low-energy experiments.

    Full Text Available Abstract: A financial management eficiently begin, primarily, with an accounting record kept in the best possible conditions, this being conditioned on the adoption of a uniform forms, rational, clear and simple accounting. Throughout history, there have been known two forms of accounting: the simple and double entry. Romanian society after 1990 underwent a substantial change in social structure, the sector on which put a great emphasis being private, that of small manufacturers, peddler, freelance, who work independently and authorized or as associative form (family enterprises, various associations (owners, tenants, etc., liberal professions, etc.. They are obliged to keep a simple bookkeeping, because they have no juridical personality. Companies with legal personality are required to keep double entry bookkeeping; therefore, knowledge and border demarcation between the two forms of organisation of accounting is an essential. The material used for this work is mainly represented by the financial and accounting documents, by the analysis of the economic, by legislative updated sources, and as the method was used the comparison method, using hypothetical data, in case of an authorized individual and a legal entity. Based on the chosen material, an authorized individual (who perform single entry accounting system and a juridical entity (who perform double entry accounting system were selected comparative case studies, using hypothetical data, were analysed advantages and disadvantages in term of fiscal, if using two accounting systems, then were highlighted some conclusion that result.

  20. Visual mislocalization during double-step saccades

    Directory of Open Access Journals (Sweden)

    Eckart eZimmermann

    2015-10-01

    Full Text Available Visual objects presented briefly at the time of saccade onset appear compressed toward the saccade target. Compression strength depends on the presentation of a visual saccade target signal and is strongly reduced during the second saccade of a double-step saccade sequence (Zimmermann et al., 2014; 2014. Here, I tested whether perisaccadic compression is linked to saccade planning by contrasting two double-step paradigms. In the same-direction double-step paradigm, subjects were required to perform two rightward 10° saccades successively. At various times around execution of the saccade sequence a probe dot was briefly flashed. Subjects had to localize the position of the probe dot after they had completed both saccades. I found compression of visual space only at the time of the first but not at the time of the second saccade. In the reverse-direction paradigm, subjects performed first a rightward 10° saccade followed by a leftward 10° saccade back to initial fixation. In this paradigm compression was found in similar magnitude during both saccades. Analysis of the saccade parameters did not reveal indications of saccade sequence preplanning in this paradigm. I therefore conclude that saccade planning, rather than saccade execution factors, is involved in perisaccadic compression.
