  1. Bob Dobinson (1943-2004)

    CERN Multimedia


    Bob Dobinson died, very unexpectedly, in England on Thursday 19th February. Bob came to CERN as a NATO Fellow in April 1968, directly after gaining his PhD in London. He joined the CERN-Rome Group, carrying out experiments both at the CERN PS and at Serpukhov. He became a CERN fellow before being appointed as a Staff Member in 1971. His professional interests were always in the area of electronics, instrumentation, networking and computing at the "front-end" of experiments. In that context, mention must be made of his outstanding work in driving the CAMAC standard, and his later work on FASTBUS; of his leadership of the European Muon Collaboration's online team and of his support, as a user, for standard PDP-11 data acquisition software; of his interest in Ethernet at all times from its very initial use to inter-connect computers to his latest work with the Gigabit and 10 Gigabit versions as the basis for data transmission within experiments. Bob lived life the way he wanted to, and wit...

    It was a great shock to the many friends and colleagues of Bob Dobinson to hear of his sudden and unexpected death in England on Thursday 19th February. Bob came to CERN in April 1968 and his professional interests were always in the area of electronics, instrumentation, networking and computing at the "front-end" of experiments. These interests included Ethernet, right from its very initial use to interconnect computers to his latest work with the Gigabit and 10 Gigabit versions as the basis for data transmission for experiments, both in the DAQ and between computing centres. Bob lived life the way he wanted to, and with great energy. He drove himself hard and generated enthusiasm amongst his collaborators to do the same. Always willing to learn from first principles about topics that interested him, he persisted with questions until he had obtained a full understanding. He was a first-class teacher, and he held positions as Visiting Professor at the Universities of Liverpool and London. He was also an exc...

  4. Bob's meltdown. (United States)

    Carr, Nicholas G


    Annette Innella is just coming into the lunchroom at Concord Machines when Bob Dunn starts screaming at her. After throwing his lunch tray against the wall, he stomps out, leaving Annette stunned. Naturally, Annette, the new senior VP for knowledge management, is beside herself. She knows her proposal to establish a cross-functional knowledge management committee is progressive thinking for this oldline manufacturer, but Bob's reaction is totally over the line. If Bob stays, she goes--that's all there is to it. Bob is contrite, but he's under a lot of pressure. The general manager of the Services Group, he's just returned from a two-week trip around the globe to gear up his troops to beat revenue targets again, despite shrinking budgets and hiring freezes. And what does he see when he gets back? An e-mail from Annette requesting that two of his best people devote half their time to what he calls her "idiotic" Knowledge Protocols Group. He's carrying the company on his back, and she's throwing this nonsense at him. Graphics specialist Paula Chancellor is surprised. Sure, Bob's gruff, but his staff loves him, and he's the only one of the big shots who ever talks to her. But HR director Nathan Singer is incensed; Bob's never been a team player, Singer complains, and it's time he learned a lesson. CEO Jay Nguyen is in a bind. Bob is his top manager; he brings in all the money. And even though future revenues are going to have to come from somewhere else, Jay is not totally behind Annette's initiative in the current business climate. He can't afford to lose Bob. But if he reins in Annette, it will look like he's condoning Bob's outburst. What should he do? Four commentators offer advice in this fictional case study.

    When, during a performance in 1964, Bob Dylan was recorded referring to a “Bob Dylan mask”, he provided a perfect soundbite for later critics keen to highlight the artist’s seemingly deliberate manipulation of his audience’s expectations. Keith Negus’s short, lucid analysis of Dylan as popular music icon opens with a discussion of the mask quip, the importance granted to it by previous Dylan commentators and the usefulness of biographical information in explaining the work of public figures. ...

  8. Bob Dylan and religion

    Directory of Open Access Journals (Sweden)

    Andreas Häger


    Full Text Available This article, which is located within the field of research on religion and popular culture, is a discussion of the relations of one particular rock artist, Bob Dylan, to religion. Religion can be seen as a recurring topic in Dylan’s work—particularly during a period at the end of the 1970s and beginning of the 1980s, often referred to as his ‘Christian era’—and also in the discourses around him. This article explores how the topic of religion appears in discourses around Bob Dylan. In this article one particular aspect of the connection between religion and popular culture is looked at: the construction of certain artists or stars as religious figures, and more specifically Bob Dylan as a case. The author does not try to discover whether Dylan is religious or not; or which religion he possibly adheres to. Rather, the author looks at how rock artists and in this case Bob Dylan are ‘constructed’ as religious figures.

    Full Text Available The new artificial bob sleigh ice track was constructed on the occasion of the XII Winter Olympics. It is 1330 m long and consists of: straight stretches, right and left turn curves, supporting zones and a circular element with a 267° opening angle. The average slope between the starting point and the goal is 18%. The section of the dike consists of a 1.45 m wide horizontal part and 0.55 m high flanges except in the curves where the flange extends into a circular security arch which serves as a retaining element. For the construction the track was subdivided into 4 m long sections, each one with its own foundation. On this foundation were placed the prefabricated supporting ribs which sustain steel laths, graders of the profile in each section. The cooling pipes were placed hanging down from the ribs by way of distance plates. The complex forms a rigid unit by means of Design Mix. The track is further completed by; he cabins at the starting point and the goal; the power plant for the technical installations; access roads to the starting points for the competing bob-sleighs; roads for transportation of equipment material.La nueva pista de hielo artificial, construida con motivo de la celebración de los XII Juegos Olímpicos de Invierno, tiene 1.330 m de longitud y está formada por: tramos rectos, curvas a derecha e izquierda, zonas de apoyo y un elemento circular con un ángulo de apertura de 267º.

  13. IDA 'Galileo Award' presented to Bob Mizon (United States)

    Miles, R.


    The Galileo Award is given once per year by the European Region of the International Dark-Sky Association (IDA) for outstanding achievements in combating light pollution in Europe. I am pleased to report that the 2006 award has been made to our very own Bob Mizon, Coordinator of the BAA Campaign for Dark Skies (CfDS). As most of you will know, the CfDS was set up by concerned members of the BAA in 1989 to counter the ever-growing tide of skyglow which has tainted the night sky over Britain since the 1950s, and to address the related problems of light trespass and energy wastage. Bob has been doing an outstanding job as Coordinator of the CfDS for many years and so it was a real pleasure for me not only to attend the 6th European Dark-Skies Symposium in Portsmouth (of which Bob was one of the organisers) but also to be present when Bob received his much-deserved award from Bob Gent, Vice-President of the Board of Directors of the IDA.

  17. Robert (Bob) L. Helmreich (1937-2012). (United States)

    Wilhelm, John; Domjan, Michael


    Presents an obituary for Robert (Bob) L. Helmreich (1937-2012). Helmreich was born April 29, 1937, in Kansas City, Missouri, the only son of Ralph and Caroline Helmreich. Bob received his undergraduate degree from Yale University in 1959. He immediately enlisted in the U.S. Navy, where he served for four years. Upon his retirement from the service he was executive officer of the USS Decatur (DD-936). Perhaps it was his service in the Navy that sparked his lifelong professional interest in how people work together in teams to accomplish technically precise goals. He returned to Yale University to obtain a doctor of philosophy degree in social psychology under Barry Collins. Bob joined the faculty at The University of Texas at Austin as an assistant professor in 1966 and remained on the faculty in the Department of Psychology until his retirement in 2007, 41 years later. During the course of his career, Helmreich published more than 200 research articles and monographs. Most of his publications dealt with issues related to airline and medical safety, and much of this work was done in collaboration with graduate students and colleagues. In recognition of his extensive contributions to improving crew performance, in 2005 Helmreich received the Lifetime Achievement Award from the Flight Safety Foundation. Helmreich also received the Franklin V. Taylor Award for Outstanding Contributions in the Field of Applied Experimental/Engineering Psychology from the American Psychological Association (APA), the Pro Bene Meritus A ward from The University of Texas (for his commitment to the liberal arts), and the David S. Sheridan Award from Albany Medical College.

  18. Neutron bound beta-decay: BOB

    Energy Technology Data Exchange (ETDEWEB)

    McAndrew, Josephine, E-mail:; Paul, Stephan; Emmerich, Ralf [TUM, Physik-Department (Germany); Engels, Ralf [Forschungszentrum Juelich, Institut Fuer Kernphysik (Germany); Fierlinger, Peter [TUM, Excellence Cluster Universe (Germany); Gabriel, Mirko; Gutsmiedl, Erwin; Mellenthin, Johannes; Schoen, Johannes; Schott, Wolfgang; Ulrich, Andreas; Grueenauer, Florian [TUM, Physik-Department (Germany); Roehrmoser, Anton [FRMII (Germany)


    An experiment to observe the bound beta-decay (BOB) of the free neutron into a hydrogen atom and an electron anti-neutrino is described. The hyperfine spin state population of the monoenergetic hydrogen atom yields the neutrino left-handedness or possible right-handed admixture as well as possible small scalar and tensor contributions to the weak force. The BOB H(2s) hyperfine states can be separated with a Lamb-Shift Spin Filter. These monoenergetic H(2s) atoms are ionised into H{sup -} by charge exchanging within an argon cell. These ions are then separated using an adaptation of a MAC-E Filter. A first experiment is proposed at the FRMII high thermal-neutron flux beam reactor SR6 through-going beam tube, where we will seek to observe this rare neutron decay-mode for the first time and determine the branching ratio. After successful completion, the hyperfine spin state population will be determined, possibly at the ILL high-flux beam reactor through-going beam tube H6-H7, where the thermal neutron flux is a factor of four larger.

  1. Obituary: Janet Akyüz Mattei, 1943-2004 (United States)

    Williams, Thomas R.; Willson, Lee Anne


    As director of the American Association of Variable Star Observers for thirty years, Janet Mattei led the organization through a series of major improvements and in the process, helped and influenced amateur and professional astronomers around the world. Having successfully tackled many challenges, however, Janet lost her battle with acute myelogenous leukemia on 22 March 2004. One of five children of Bella and Baruk Akyüz, Janet was born on 2 January 1943 in Bodrum, Turkey and received her pre-collegiate education there. She attended Brandeis University from 1962 until 1965 on a full Wein Scholarship, earning a BA in General Science. After eighteen months of supervising a cardiopulmonary laboratory, in 1967 she returned to Turkey to teach physics and mathematics in a high school, and then entered graduate school at Turkey's Ege University. Janet learned of the summer scholarships available at the Maria Mitchell Observatory on Nantucket, and applied to observatory director Dorrit Hoffleit for the opportunity to come back to the United States and learn about variable stars. That summer (1969) she learned to love variable stars, became acquainted with the AAVSO, and met her future husband, Michael Mattei. In 1970, after she earned her master's degree in astronomy at Ege University, Janet entered the University of Virginia where she earned a second master's degree in 1972 with a thesis on T Tauri stars. After receiving her degree in Virginia, Janet married Mike Mattei and became an assistant to Margaret Mayall at AAVSO headquarters. When Mayall decided to retire in 1973, the AAVSO Council asked Janet to assume the helm as director of the association. With such a sudden advance in her responsibilities, Janet had to rapidly learn the management side of running the organization as well as keep up with the day-to-day scientific activities - responding to requests for data, recording observations as pencil-points on paper charts, and predicting future maxima of long period variables. She accelerated a ten-year project to digitize all of AAVSO's archived as well as current data, without which a century of AAVSO observations would now be nearly inaccessible. In the mid-1970s professional interest in the cataclysmic variables began to ramp up. When she received the first requests for an AAVSO visual observing campaign coordinated with observations by orbiting observatories as well as large ground based telescopes, Janet accepted the invitation as both an opportunity and a challenge. AAVSO observers responded marvelously and, coupled with Janet's astute forecasting of when cataclysmic variables were likely to brighten again, the program emerged as one of the major technical successes of her tenure. Many AAVSO members will never forget their excitement when France Córdova came to our Fall meeting in 1978 to announce to the astronomical world that X-rays from SS Cyg had been detected by HEAO-1 on the first occasion after the satellite reached orbit when AAVSO observers reported that the star was brightening to a maximum. It was a moment of tremendous pride for everyone, most of all for Janet. It was a success that was repeated frequently in over six hundred subsequent coordinated observing runs with various satellites. This success greatly increased the impact of AAVSO on current astronomical research, enhanced its reputation, and also provided a more immediate thrill for the observers than the ongoing commitment to monitor slowly varying stars. The late 1970s and early 1980s were a period of substantial inflation in our nation's economy. Furthermore, staff turnover slowed progress with the data processing work, while observations coming to AAVSO from international variable star organizations and independent observers, especially from behind the iron curtain, were increasing rapidly. Faced with rising costs at the same time additional staff was needed to pursue the data processing problems, Janet reacted characteristically: she began taking night courses in management, data processing, fund raising, and other topics that could help her handle the AAVSO work load more efficiently. Nor was her formal education in astronomy quite complete, for during that difficult period she completed writing her dissertation and earned a PhD in astronomy from Ege University in 1982. AAVSO's headquarters on Concord Avenue was increasingly crowded and also insecure, as the historical data were stored in a building that was vulnerable to fire. In August 1985 long-term AAVSO secretary and benefactor Clinton Banker Ford (BAAS, 1994:1602) solved these problems by donating a new headquarters building at 25 Birch Street in Cambridge. Janet managed the move into the AAVSO's present facilities masterfully, and then led planning for a dedication of the building combined with a celebration of the AAVSO's seventy-fifth anniversary. It is a measure of Janet's growth in stature in the professional community that Ricardo Giacconi, then director of the Space Telescope Science Institute, was the keynote speaker for the celebration and it was attended by the leaders of variable star organizations from a number of countries. The meeting marked a major turning point in the affairs of AAVSO as well as in Janet's own outlook. Substantially more confident in her abilities as a manager and leader of the organization, Janet never looked back. Janet's international contacts, through her active participation in the International Astronomical Union (IAU), led her to participate in 1987 as one of the organizers of an IAU colloquium in Paris on the contribution of amateurs to astronomy, the first of her many later involvements in the field of professional-amateur (Pro-Am) cooperation. During that meeting, the Sociétié Astronomique de France (SAF) honored Janet with their Centennial Award for her leadership in variable star astronomy and within the AAVSO. She received an invitation from the Vereniging voor Sterrenkunde, the variable star observers in Belgium for AAVSO to hold its first European meeting in Brussels in July 1990. The meeting proved a huge success, and was followed in 1997 by a second AAVSO European meeting in Sion, Switzerland and a Pan-Pacific meeting in 2003 in Hawaii. Through Janet's leadership, AAVSO reached out to the observers who were already supporting the association with their observations. One of Janet's strong interests was in education. Using a grant from the National Science Foundation, she led efforts to create Hands-On Astrophysics (HOA) based largely on variable stars and AAVSO data. Though it took several years to develop, HOA became the basis for a number of popular teacher workshops and is sure to lead many high school students into careers in science. Janet also helped many future professionals in astronomy, including Karen Meech and Peter Garnavich, and a few in other areas, by providing opportunities for them to work at headquarters during their studies or during an intermission in their formal schooling. Janet was active in, and honored by, other professional and amateur organizations. A member of the American Astronomical Society (AAS), she received the AAS's George van Biesbroeck award in 1993, served on the AAS Annenberg Award Committee (1994-1997) and served as the first chair of the AAS Professional Amateur Cooperation Committee. Also in 1993, the Astronomical League with their Leslie Peltier Award honored Janet for her leadership of the AAVSO and contributions to variable star astronomy. Janet was elected a director of the Astronomical Society of the Pacific (ASP) and served six years in that capacity (1994-2000), co-chairing at least one Pro-Am workshop with the ASP. She was a member of three IAU Commissions over her thirty-five years of membership in that organization. In 1995, Janet was honored by the award of the Royal Astronomical Society's Jackson-Gwilt Medal and was the first recipient of the Giovanni Battista Lacchini Award for collaboration with amateur astronomers from Unione Astrofili Italiana. To honor her professional achievements, an asteroid was named for her (11695 Mattei). She always felt that these awards honored not just of her own work, but also the contributions of the members and observers who make up the AAVSO community. Janet Mattei left a very different AAVSO than the one she took over in 1973. From 150,000 observations arriving annually and being handled on paper, now 500,000 arrive each year and are mostly processed and posted automatically. The association has a substantial endowment and owns its headquarters building in Cambridge, Massachusetts. The historical archive has been put into usable form, following two multi-year investments in digitization and validation. The activities of the AAVSO have been extended to include notifying space and ground observatories that particular objects are erupting and to capturing short-lived gamma ray burst afterglows. The organization's ties to those with similar missions around the world have been strengthened and, increasingly, the AAVSO's International Variable Star Database incorporates their data. Janet's final illness was followed, through email bulletins, by hundreds of her friends and colleagues around the world. Characteristically, during a remission-and-recovery time between treatments, Janet reached out by phone and email to many of her AAVSO associates and friends, and resumed her habit of sending appropriate cards for special occasions. The more than 200 email "memoriam" notes posted on the AAVSO web site after her death show that all who knew her, even if only briefly, considered her a friend, a mentor, or a fine example of a scientist and leader.

  3. Function of head-bobbing behavior in diving little grebes. (United States)

    Gunji, Megu; Fujita, Masaki; Higuchi, Hiroyoshi


    Most birds show a characteristic head movement that consists of head stabilization and quick displacement. In this movement, which is analogous to saccadic eye movement in mammals, head stabilization plays an important role in stabilizing the retinal image. This head movement, called "head bobbing", is particularly pronounced during walking. Previous studies focusing on anatomical and behavioral features have pointed out that visual information is also important for diving birds, indicating its significance in the head movements of diving birds. In the present study, the kinematic and behavioral features of head bobbing in diving little grebes were described by motion analysis to identify the head movement in diving birds. The results showed that head-bobbing stroke (HBS) consisted of a thrust phase and a hold phase as is typical for head bobbing during walking birds. This suggests that HBS is related to visual stabilization under water. In HBS, grebes tended to dive with longer stroke length and smaller stroke frequency than in non-bobbing stroke. This suggests that the behavior, which is related to vision, affects the kinematic stroke parameters. This clarification of underwater head movement will help in our understanding not only of vision, but also of the kinematic strategy of diving birds.

  9. Essay: Bob Siemann-SLC Days at SLAC

    Energy Technology Data Exchange (ETDEWEB)

    Raubenheimer, Tor O.; /SLAC


    Bob Siemann was a great experimentalist and an excellent teacher.We will greatly miss him. Bob came to SLAC in early 1991 to work on the Stanford Linear Collider (SLC). The SLC was a challenging accelerator which began operating in the late 1980's but still had numerous obstacles to be overcome years into operation. One of the compounding difficulties was making reproducible measurements, since the stability of the collider was poor and the diagnostics were insufficient. Bob dove into this challenge and helped design experiments and diagnostics that provided further clarity. I first got to know Bob while I was still a graduate student, trying to finish my thesis and performing some experimental studies on the SLC, which, at the time, was proving to be very difficult. Most of my expertise had been in beam theory and simulation. Dealing with the real issues of the accelerator was challenging. Bob helped me understand the difference between systematic and statistical errors, and separate operational issues from the fundamental physics. His way of teaching was not to provide an explanation but to ask enough questions so that I could find the answer on my own - this was the best way to learn. I later asked Bob to be a reader on my thesis. As in all things, he took this role extremely seriously. He read through the draft and marked every page to the point where I was regretting my decision. However, his questions again helped me understand my own work better and greatly improved my thesis.

He made people think for themselves and refused to simply provide answers. He also worked hard himself, expressing real interest and curiosity. After the studies of the SLC damping rings identified a sawtooth instability due to the vacuum chamber impedance as a source of many downstream fluctuations, Bob took charge of upgrading the rings.

  10. A C-terminal acidic domain regulates degradation of the transcriptional coactivator Bob1. (United States)

    Lindner, John M; Wong, Christina S F; Möller, Andreas; Nielsen, Peter J


    Bob1 (Obf-1 or OCA-B) is a 34-kDa transcriptional coactivator encoded by the Pou2af1 gene that is essential for normal B-cell development and immune responses in mice. During lymphocyte activation, Bob1 protein levels dramatically increase independently of mRNA levels, suggesting that the stability of Bob1 is regulated. We used a fluorescent protein-based reporter system to analyze protein stability in response to genetic and physiological perturbations and show that, while Bob1 degradation is proteasome mediated, it does not require ubiquitination of Bob1. Furthermore, degradation of Bob1 in B cells appears to be largely independent of the E3 ubiquitin ligase Siah. We propose a novel mechanism of Bob1 turnover in B cells, whereby an acidic region in the C terminus of Bob1 regulates the activity of degron signals elsewhere in the protein. Changes that make the C terminus more acidic, including tyrosine phosphorylation-mimetic mutations, stabilize the instable murine Bob1 protein, indicating that B cells may regulate Bob1 stability and activity via signaling pathways. Finally, we show that expressing a stable Bob1 mutant in B cells suppresses cell proliferation and induces changes in surface marker expression commonly seen during B-cell differentiation.

  11. Partial reversion at the bobbed locus of Drosophila melanogaster. (United States)

    Terracol, R; Iturbide, Y; Prud'Homme, N


    In Drosophila melanogaster the tandemly arranged repetitive sequences coding for 18S and 28S rRNA are heterogenous at the level of the spacers between units and insertions that interrupt many 28S rRNA genes. This heterogeneity contrasts with the homogeneity of the regions transcribed into 18S and 28S rRNA. Homogenization and evolution of repetitive genes are usually explained by conversion, amplification events or unequal crossovers. In this paper we studied the change in rDNA patterns associated with partial reversion of bobbed mutations. In most cases, no increase in rDNA gene number, but a new repartition of gene types were found.

  17. BOB.1/OBF.1 controls the balance of TH1 and TH2 immune responses. (United States)

    Brunner, Cornelia; Sindrilaru, Anca; Girkontaite, Irute; Fischer, Klaus-Dieter; Sunderkötter, Cord; Wirth, Thomas


    BOB.1/OBF.1 is a transcriptional coactivator essential at several stages of B-cell development. In T cells, BOB.1/OBF.1 expression is inducible by co-stimulation. However, a defined role of BOB.1/OBF.1 for T-cell function had not been discovered so far. Here, we show that BOB.1/OBF.1 is critical for T helper cell function. BOB.1/OBF.1(-/-) mice showed imbalanced immune responses, resulting in increased susceptibility to Leishmania major infection. Functional analyses revealed specific defects in TH1 and TH2 cells. Whereas expression levels of TH1 cytokines were reduced, the secretion of TH2 cytokines was increased. BOB.1/OBF.1 directly contributes to the IFNgamma and IL2 promoter activities. In contrast, increased TH2 cytokine production is controlled indirectly, probably via the transcription factor PU.1, the expression of which is regulated by BOB.1/OBF.1. Thus, BOB.1/OBF.1 regulates the balance of TH1 versus TH2 mediated immunity.

  18. Btk expression is controlled by Oct and BOB.1/OBF.1. (United States)

    Brunner, Cornelia; Wirth, Thomas


    BOB.1/OBF.1 is a lymphocyte-restricted transcriptional coactivator. It binds together with the Oct1 and Oct2 transcription factors to DNA and enhances their transactivation potential. Mice deficient for the transcriptional coactivator BOB.1/OBF.1 show several defects in differentiation, function and signaling of B cells. In search of BOB.1/OBF.1 regulated genes we identified Btk--a cytoplasmic tyrosine kinase-as a direct target of BOB.1/OBF.1. Analyses of the human as well as murine Btk promoters revealed a non-consensus octamer site close to the start site of transcription. Here we show that Oct proteins together with BOB.1/OBF.1 are able to form ternary complexes on these sites in vitro and in vivo. This in turn leads to the induction of Btk promoter activity in synergism with the transcription factor PU.1. Btk, like BOB.1/OBF.1, plays a critical role in B cell development and B cell receptor signalling. Therefore the down-regulation of Btk expression in BOB.1/OBF.1-deficient B cells could be related to the functional and developmental defects observed in BOB.1/OBF.1-deficient mice.

  19. Orphan receptor GPR15/BOB is up-regulated in rheumatoid arthritis. (United States)

    Cartwright, Alison; Schmutz, Caroline; Askari, Ayman; Kuiper, Jan-Herman; Middleton, Jim


    Chemokine receptors on leukocytes mediate the recruitment and accumulation of these cells within affected joints in chronic inflammatory diseases such as rheumatoid arthritis (RA). Identification of involved receptors offers potential for development of therapeutic interventions. The objective of this study was to investigate the expression of orphan receptor GPR15/BOB in the synovium of RA and non-RA patients and in peripheral blood of RA patients and healthy donors. GPR15/BOB protein and messenger RNA expression were examined in RA and non-RA synovium by immunofluorescence and reverse-transcription polymerase chain reaction (RT-PCR) respectively. GPR15/BOB expression on peripheral blood leukocytes was analysed by flow cytometry and GPR15/BOB messenger RNA was examined in peripheral blood monocytes by RT-PCR. GPR15/BOB protein was observed in CD68+ and CD14+ macrophages in synovia, with greater expression in RA synovia. GPR15/BOB protein was expressed in all patient synovia whereas in non-RA synovia expression was low or absent. Similarly GPR15/BOB messenger RNA was detected in all RA and a minority of non-RA synovia. GPR15/BOB protein was expressed on peripheral blood leukocytes from RA and healthy individuals with increased expression by monocytes and neutrophils in RA. GPR15/BOB messenger RNA expression was confirmed in peripheral blood monocytes. In conclusion GPR15/BOB is expressed by macrophages in synovial tissue and on monocytes and neutrophils in peripheral blood, and expression is up-regulated in RA patients compared to non-RA controls. This orphan receptor on monocytes/macrophages and neutrophils may play a role in RA pathophysiology.

    Mark, Andrew


    Full Text Available This paper describes Bob Wiseman’s allegorical piece, Uranium, arguing that it accesses emotion to alter the consciousness of percipients. Audiences respond with unusual intensity to Uranium’s tragic environmental narrative. By using puppet theatre, film, comedy, and song to win their trust, Wiseman is able to shock his spectators. With interviews and consideration of the semiotic content of Uranium, I explore possibilities for activation of ecological consciousness through performing arts. Building on the shared ideas of Heinrich von Kleist, Gregory Bateson, and Thomas Turino, I argue that Wiseman offers one particularly useful mechanism to advance environmental concerns and learning through the arts. This paper seeks to bridge environmental and (ethnomusicological thought, and has specific relevance to the growing field of ecomusicology, presenting a musical ethnographic case-study in singer-song-writer activism.

    The B fields in OB stars (BOB) survey is an ESO large programme collecting spectropolarimetric observations for a large number of early-type stars in order to study the occurrence rate, properties, and ultimately the origin of magnetic fields in massive stars. As of July 2014, a total of 98 objects were observed over 20 nights with FORS2 and HARPSpol. Our preliminary results indicate that the fraction of magnetic OB stars with an organised, detectable field is low. This conclusion, now independently reached by two different surveys, has profound implications for any theoretical model attempting to explain the field formation in these objects. We discuss in this contribution some important issues addressed by our observations (e.g., the lower bound of the field strength) and the discovery of some remarkable objects.

    Full Text Available Taking issue with approaches to Bob Dylan’s art that are preoccupied with his lyrics, this article suggests a route into thinking about his music by focusing on how Dylan’s vocal melodies work at the intersection of speech and singing. Drawing on Gino Stefani’s work on popular melodies, this article explores this issue through a discussion of how people sing along with Dylan’s songs at concerts. The discussion focuses on the song “It Ain’t Me Babe,” and examines more general points about the ways in which Dylan’s melodies connect with the everyday lives of his listeners.

  3. Tangled up in grief: Bob Dylan's songs of separation. (United States)

    Smith, Keverne

    This article argues that much can be learned about the ways in which individuals grieve through a careful analysis of the presentation of loss in creative fiction, especially in terms of unconscious and uncensored responses presented indirectly through figurative language and structural patterns. It takes Bob Dylan's collection of songs about the anguish caused by lost love, Blood on the Tracks, as an example. An examination of the songs included in, and some rejected for, the album reveals developing responses to grief resulting from relationship breakdown, including the search for the absent one and for reconciliation; the intrusion of deep pain into everyday situations; the problem of infidelity and guilt; the attempt to reach a more detached perspective; the consequences of the pain becoming unbearable; and the attempt at a kind of closure. Taken together, the songs reveal how complex and contradictory responses to the agony of loss can be.

  5. BOB.1 of the channel catfish, Ictalurus punctatus: not a transcriptional coactivator? (United States)

    Richard, Mara L Lennard; Hikima, Jun-ichi; Wilson, Melanie R; Miller, Norman W; Cunningham, Charles; Warr, Gregory W


    Expression of the immunoglobulin heavy chain (IGH) locus of the channel catfish (Ictalurus punctatus) is driven by the Emu3' enhancer, whose core region contains two octamer motifs and a muE5 site. Orthologues of the Oct1 and Oct2 transcription factors have been cloned in the channel catfish and shown to bind to the octamer motifs within the core enhancer. While catfish Oct2 is an activator of transcription, catfish Oct1 failed to drive transcription and may act as a negative regulator of IGH transcription. In mammals, the Oct co-activator BOB.1 (B cell Oct-binding protein1, also known as OCA-B and OBF-1) greatly enhances the transcriptional activity of Oct factors and plays an important role in the development of the immune system. An orthologue of BOB.1 has been cloned in the catfish, and its function characterized. The POU binding domain of the catfish BOB.1 was found to be 95% identical at the amino acid level with the binding domain of human BOB.1, and all the residues directly involved in binding to the Oct-DNA complex were conserved. Despite this conservation, catfish BOB.1 failed to enhance transcriptional activation mediated by endogenous or co-transfected catfish Oct2, and failed to rescue the activity of the inactive catfish Oct1. Electrophoretic mobility shift assays showed that catfish BOB.1 was capable of binding both catfish Oct1 and Oct2 when they formed a complex with the Oct motif. Analysis of recombinant chimeric catfish and human BOB.1 proteins demonstrated that the failure to drive transcription was due to the lack of a functional activation domain within the catfish BOB.1.

  6. NF-κB-dependent signals control BOB.1/OBF.1 and Oct2 transcriptional activity in B cells. (United States)

    Kilzheimer, Melanie; Quandt, Jasmin; Langhans, Julia; Weihrich, Petra; Wirth, Thomas; Brunner, Cornelia


    The transcriptional co-activator BOB.1/OBF.1 is crucial for Octamer-driven transcription in B cells. BOB.1/OBF.1-deficiency leads to tremendous defects in B-cell development and function. Therefore, in the past research focused on the identification of BOB.1/OBF.1 target genes. However, the regulation of BOB.1/OBF.1 expression itself is poorly understood. Here we show that in B cells NF-κB as well as to some extent NFAT proteins are involved in the activation of basal as well as inducible BOB.1/OBF.1 expression by direct binding to the BOB.1/OBF.1 promoter. Moreover, the analysis of different inducers of NF-κB, like several TLR ligands, TNF-α, BAFF, or LTα1β2, revealed that both the canonical and noncanonical NF-κB pathways are involved in the induction of BOB.1/OBF.1 gene. The identification of so far unknown inducers that regulate BOB.1/OBF.1 expression in B cells provides novel insights in the potential function of BOB.1/OBF.1 during different aspects of B-cell development and function.

  7. Effect of sulfites on the performance of LiBOB/{gamma}-butyrolactone electrolytes

    Energy Technology Data Exchange (ETDEWEB)

    Ping, Ping; Wang, Qingsong; Sun, Jinhua [State Key Laboratory of Fire Science, University of Science and Technology of China, Hefei 230026, Anhui (China); Feng, Xuyong; Chen, Chunhua [Department of Materials Science and Engineering, University of Science and Technology of China, Hefei 230026, Anhui (China)


    {gamma}-Butyrolactone (GBL) increases the irreversible capacity of lithium ion battery when it is employed as the solvent for the lithium bis(oxalate)borate (LiBOB)-based electrolyte. To solve this problem, four sulfites are introduced to the electrolyte. The effects of ethyl sulfite (ES), propylene sulfite (PS), dimethyl sulfite (DMS) and diethyl sulfite (DES) on the LiBOB/GBL-based electrolytes are studied. The ionic conductivity, electrochemical stability, cycle performance and thermal stability of the sulfite containing electrolytes are tested and compared with that of the common electrolyte and the 1 M LiBOB/GBL electrolyte. The results indicate that the cyclic sulfites ES and PS show little benefit to the performance of the electrolyte. However, the linear sulfites DMS and DES could increase the ionic conductivity of the electrolyte and form an effective SEI film on the anode surface. In particular, the 1 M LiBOB/GBL+DMS (3:1 wt.) electrolyte mitigates the irreversible capacity and enhances the first coulomb efficiency and the capacity retention. The thermal stability of the DMS containing electrolyte is also improved and is better than that of the common electrolyte. These beneficial effects make them possibly to be a promising cosolvent for the LiBOB/GBL electrolyte. (author)

  11. The transcriptional coactivator Bob1 promotes the development of follicular T helper cells via Bcl6. (United States)

    Stauss, Dennis; Brunner, Cornelia; Berberich-Siebelt, Friederike; Höpken, Uta E; Lipp, Martin; Müller, Gerd


    Follicular T helper (Tfh) cells are key regulators of the germinal center reaction and long-term humoral immunity. Tfh cell differentiation requires the sustained expression of the transcriptional repressor Bcl6; however, its regulation in CD4(+)T cells is incompletely understood. Here, we report that the transcriptional coactivator Bob1, encoded by thePou2af1gene, promotes Bcl6 expression and Tfh cell development. We found that Bob1 together with the octamer transcription factors Oct1/Oct2 can directly bind to and transactivate theBcl6andBtlapromoters. Mixed bone marrow chimeras revealed that Bob1 is required for the expression of normal levels of Bcl6 andBTLA, thereby controlling the pool size and composition of the Tfh compartment in a T cell-intrinsic manner. Our data indicate that T cell-expressed Bob1 is directly involved in Tfh cell differentiation and required for mounting normal T cell-dependent B-cell responses.

  17. Barack Obama Blindness (BOB): Absence of Visual Awareness to a Single Object. (United States)

    Persuh, Marjan; Melara, Robert D


    In two experiments, we evaluated whether a perceiver's prior expectations could alone obliterate his or her awareness of a salient visual stimulus. To establish expectancy, observers first made a demanding visual discrimination on each of three baseline trials. Then, on a fourth, critical trial, a single, salient and highly visible object appeared in full view at the center of the visual field and in the absence of any competing visual input. Surprisingly, fully half of the participants were unaware of the solitary object in front of their eyes. Dramatically, observers were blind even when the only stimulus on display was the face of U.S. President Barack Obama. We term this novel, counterintuitive phenomenon, Barack Obama Blindness (BOB). Employing a method that rules out putative memory effects by probing awareness immediately after presentation of the critical stimulus, we demonstrate that the BOB effect is a true failure of conscious vision.

  20. Gel polymer electrolyte based on LiBOB and PAN for the application in dye-sensitized solar cells (United States)

    Arof, A. K.; Jun, H. K.; Sim, L. N.; Kufian, M. Z.; Sahraoui, B.


    Dye-sensitized solar cells (DSSCs) have been fabricated using metal complex N3 dye coupled with LiBOB and PAN-based gel polymer electrolyte (GPE). Conductivity of the GPE at room temperature was 1.2 × 10-2 S cm-1. The deconvoluted vibration spectra at different temperatures between 1000 and 970 cm-1 show the existence of ion pairs and free ions. Overall efficiency and fill factor of the DSSC with LiBOB-BMII-PAN-I2 GPE system is 0.65% and 48% respectively. The cell with LiBOB-BMII-PAN-I2 GPE system appears to be stable under varied light intensity attributed to the presence of redox couple mediator in the GPE. Impedance measurements show that the DSSC with LiBOB-BMII-PAN-I2 GPE has longer electron lifetime which suggests a lower electron recombination rate.

    Jun, H. K.; Buraidah, M. H.; Noor, M. M.; Kufian, M. Z.; Majid, S. R.; Sahraoui, B.; Arof, A. K.


    Co-sensitized solar cells have been fabricated using metal complex N3 dye and Ag2S/CdS quantum dots coupled with LiBOB-based liquid electrolyte. Quantum dots (QDs) were synthesized via the successive ionic layer adsorption and reaction (SILAR) route. The absorbance and band gap energy of Ag2S and CdS QDs were determined. Their refractive indices were observed to be in the range of 1.5175-1.5200. It has been shown that LiBOB-based liquid electrolyte is able to function in the QD/N3 dye co-sensitized solar cells but some stability issues of the QD were observed in the electrolyte system containing iodide whereby the QD-sensitized TiO2 was easily etched. Overall efficiencies and fill factors of the co-sensitized solar cells varied from 0.98% to 1.66% and 40% to 46% respectively. CdS QD was shown to be effective when coupled with polysulfide electrolyte while Ag2S QD was favorable towards the LiBOB-based liquid electrolyte.

    J.W. Kaczmar


    Full Text Available The paper presents a research on abrasion resistance of aluminium-based composites consisting of EN AC-44200 matrix reinforcedwith AlB2BOB3B particles. The examinations revealed that wear intensity of the composites decreased with increasing volume fraction of the particles. Much more intensive abrasive wear was observed on the first kilometre in comparison to the wear on the subsequent distances, i.e. from 1 to 3.5 km and from 3.5 to 8.5 km of the wear distance. Microscopic examinations permitted determining the way and type of wear occurring in the examined materials. In the case of the AC-44200 matrix, typical adhesive wear is observed. In composite materials however, abrasive wear prevails over adhesive wear. Increased volume fraction of AlB2BOB3B particles in composite materials results in increasing friction factor in average by 0.250 per each 10 vol.%. Wear of the cast-iron counterspecimen is also strongly dependent on volume fraction of the reinforcing particles. The counterspecimen demonstrates the largest wear when working in contact with a composite material containing 40 vol.% of AlB2BOB3B particles.

    Full Text Available Abstract Multimedia services over resource constrained wireless sensor networks (WSNs face a performance bottleneck issue from the gateway node to the sink node. Therefore, the queue management at the gateway node is crucial for diversified messages conveyed from the front nodes to the sink node. In this article, beacon order-based random early detection (BOB-RED queue management is proposed. BOB-RED is a dynamic adaptation scheme based on adjusting beacon interval and superframe duration in the IEEE 802.15.4 MAC superframe accompanied with RED queue management scheme to increase the transmission efficiency of multimedia over WSNs. We focus on the performance improvement upon different traffic loads over WSNs. Evaluation metrics include end-to-end delay, packet delivery ratio, and energy consumption in IEEE 802.15.4 beacon enabled mode. Simulation results show that BOB-RED can effectively decrease end-to-end delay and energy consumption compared to the DropTail scheme.

    In natural and social science, many events happened at different space-times may be closely entangled or correlated. Two events, $A$ (Alice) and $B$ (Bob) are defined as correlated if one event is determined by another, say, $B=\\hat{f}A$ for suitable $\\hat{f}$ operators. Can we find these kinds of correlated solutions from the known physically significant models? Alternatively, can we establish/derive some significant physical models to describe these kinds of correlated phenomena? Taking KdV and coupled KdV systems as examples, we can find some types of models (defined as Alice-Bob KdV systems) to exhibit the existence on the correlated solutions linked with two events, event $A=A(x,\\ t)$ and event $B=B(x',\\ t')=\\hat{f}A$ happened at $\\{x,\\ t\\}$ and $\\{x',\\ t'\\}$ respectively. The idea of this letter is valid not only for the physical problems related to the KdV systems but also for all physical problems which can be described by arbitrary continuous or discrete mathematical models.

  10. B fields in OB stars (BOB): Concluding the FORS 2 observing campaign (United States)

    Schöller, M.; Hubrig, S.; Fossati, L.; Carroll, T. A.; Briquet, M.; Oskinova, L. M.; Järvinen, S.; Ilyin, I.; Castro, N.; Morel, T.; Langer, N.; Przybilla, N.; Nieva, M.-F.; Kholtygin, A. F.; Sana, H.; Herrero, A.; Barbá, R. H.; de Koter, A.; BOB Collaboration


    Aims: The B fields in OB stars (BOB) Collaboration is based on an ESO Large Programme to study the occurrence rate, properties, and ultimately the origin of magnetic fields in massive stars. Methods: In the framework of this program, we carried out low-resolution spectropolarimetric observations of a large sample of massive stars using FORS 2 installed at the ESO VLT 8 m telescope. Results: We determined the magnetic field values with two completely independent reduction and analysis pipelines. Our in-depth study of the magnetic field measurements shows that differences between our two pipelines are usually well within 3σ errors. From the 32 observations of 28 OB stars, we were able to monitor the magnetic fields in CPD -57° 3509 and HD 164492C, confirm the magnetic field in HD 54879, and detect a magnetic field in CPD -62° 2124. We obtain a magnetic field detection rate of 6 ± 3% for the full sample of 69 OB stars observed with FORS 2 within the BOB program. For the preselected objects with a v sin i below 60 km s-1, we obtain a magnetic field detection rate of 5 ± 5%. We also discuss X-ray properties and multiplicity of the objects in our FORS 2 sample with respect to the magnetic field detections. Based on observations made with ESO Telescopes at the La Silla Paranal Observatory under program ID 191.D-0255(E,G).

  12. Property Analysis of Ethanol--Natural Gasoline--BOB Blends to Make Flex Fuel

    Energy Technology Data Exchange (ETDEWEB)

    Alleman, Teresa L. [National Renewable Energy Lab. (NREL), Golden, CO (United States); Yanowitz, Janet [Ecoengineering, Inc., Sharonville, OH (United States)


    Ten natural gasolines were analyzed for a wide range of properties, including Reid vapor pressure (RVP), benzene, sulfur, distillation, stability, metals, and aromatic content, to determine their quality. Benzene and sulfur content were sufficiently low in all but one of the samples that they could be blended without further upgrading. Four of these samples were selected to blend with blendstock for oxygenate blending (BOB) and ethanol to produce E51, E70, and E83 blends, targeting 7.8 and 9.0-psi finished fuels. The volume of each component in the blend was estimated using the Reddy model, with the assumption that the BOB and natural gasoline blend linearly and behave as a single component in the model calculations. Results show that the Reddy model adequately predicts the RVP of the finished blend for E51 and E70, but significantly underpredicts the RVP of E83 blends by nearly 2 psi. It is hypothesized that the underprediction is a function of the very low aromatic content of the E83 blends, even compared to the E51 and E70 blends.

  13. On vision in birds: coordination of head-bobbing and gait stabilises vertical head position in quail (United States)


    Introduction Head-bobbing in birds is a conspicuous behaviour related to vision comprising a hold phase and a thrust phase. The timing of these phases has been shown in many birds, including quail, to be coordinated with footfall during locomotion. We were interested in the biomechanics behind this phenomenon. During terrestrial locomotion in birds, the trunk is subjected to gait-specific vertical oscillations. Without compensation, these vertical oscillations conflict with the demands of vision (i.e., a vertically stable head position). We tested the hypothesis that the coordination between head-bobbing and trunk movement is a means of reconciling the conflicting demands of vision and locomotion which should thus vary according to gait. Results Significant differences in the timing of head-bobbing were found between gaits. The thrust phase was initiated just prior to the double support phase in walking (vaulting) trials, whereas in running (bouncing) trials, thrust started around midstance. Altering the timing of head-trunk-coordination in simulations showed that the timing naturally favoured by birds minimizes the vertical displacement of the head. When using a bouncing gait the timing of head bobbing had a compensatory effect on the fluctuation of the potential energy of the bird’s centre of mass. Conclusion The results are consistent with expectations based on the vertical trunk fluctuations observed in biomechanical models of vaulting and bouncing locomotion. The timing of the head-bobbing behaviour naturally favoured by quail benefits vision during vaulting and bouncing gaits and potentially helps reducing the mechanical cost associated with head bobbing when using a bouncing gait.

  14. What does Batman think about SpongeBob? children's understanding of the fantasy/fantasy distinction. (United States)

    Skolnick, Deena; Bloom, Paul


    Young children reliably distinguish reality from fantasy; they know that their friends are real and that Batman is not. But it is an open question whether they appreciate, as adults do, that there are multiple fantasy worlds. We test this by asking children and adults about fictional characters' beliefs about other characters who exist either within the same world (e.g., Batman and Robin) or in different worlds (e.g., Batman and SpongeBob). Study 1 found that although both adults and young children distinguish between within-world and across-world types of character relationships, the children make an unexpected mistake: they often claim that Batman thinks that Robin is make believe. Study 2 used a less explicit task, exploring intuitions about the actions of characters-whom they could see, touch, and talk to--and found that children show a mature appreciation of the ontology of fictional worlds.

  18. No man is an island. A personal tribute to Bob Blanchard and ethoexperimental approaches to the study of behaviour. (United States)

    Rodgers, Robert John


    I first met Bob Blanchard at an international conference in Paris some 40 years ago. We collaborated intensively during the late 1980s/early 1990s on the ethopharmacology of antipredator defence in wild and laboratory rats, and remained good friends until his untimely passing in November 2013. Bob will undoubtedly be remembered as one of the most influential behavioural neuroscientists of the 20th century and, with Caroline, the most eloquent advocate of ethoexperimental approaches to the study of behaviour. In this brief trip down memory lane, I describe when and where Bob and I first met and how, over a lengthy period, he directly and indirectly helped shape my own research career. His profound influence in this regard is illustrated by reference to not only our collaborative research on antipredator behaviour but also my other work on the ethopharmacology of agonistic behaviour, social conflict analgesia, anxiety, and appetite. The element common to all of this work has been ethoexperimental analysis and, for teaching me the true value of this approach, I shall always remain indebted to the big man. Literally and figuratively, Bob was most certainly larger than life.

  19. BOB.1-positive Classical Hodgkin's Lymphoma Carries Hypermethylation of Its Promoter as Epigenetic Marker of Gene-silencing Memory. (United States)

    Watanabe, Takafumi; Kitazawa, Riko; Mizuno, Yosuke; Kuwahara, Natsumi; Ito, Chizu; Sugita, Atsuro; Haraguchi, Ryuma; Kitazawa, Sohei


    Analysis of archival formalin-fixed, paraffin-embedded (FFPE) pathological specimens of three case of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) and three cases of classical Hodgkin lymphoma (CHL) revealed that hypermethylation of the BOB.1 gene promoter was exclusively observed in CHL. A discrepancy was observed, however, between the methylation status of the BOB.1 gene promoter and its expression in the EBV-positive mixed cellular CHL (MCCHL). Since MCCHL lacks the typical B-cell phenotype even in the presence of abundant BOB.1 transcription factors, functional activity of BOB.1 may be lost or reduced by a mechanism other than epigenetic gene silencing. When some tumor-suppressor gene products have lost their biological function, impact or significance of derepression of such genes may be little. Therefore, when interpreting immunohistochemical results for diagnostic or research purposes, it must be borne in mind that apparent positive immunostaining can merely be the result of chromatin remodeling and that such transient expression often has little functional significance. Any apparent positive immunohistochemical result needs to be interpreted carefully with the help of the hypermethylation status as a molecular marker of gene silencing memory.

  1. Emotional fluctuations in Bob Dylan's lyrics measured by the dictionary of affect accompany events and phases in his life. (United States)

    Whissell, Cynthia


    Lyrics for Bob Dylan's songs between 1962 and 2001 (close to 100,000 words) were scored with the help of the Dictionary of Affect in Language (Whissell, 2006). Means for Pleasantness, Activation, and Imagery are reported for 22 Blocks characterizing this time span. Significant but weak differences across Blocks were found for all three measures at the level of individual words. Emotional fluctuations in words included in Bob Dylan's lyrics accompanied events and phases in his life, although they were not entirely dictated by these events. Dylan used more highly Imaged and more Active words at times when his work was critically acclaimed. More Passive word choices characterized times of prolonged stress, and more Pleasant choices times of experimentation. Dylan's three popularity peaks were used to divide the singer's career into three stages (rhetor, poet, sage) which differed in terms of pronouns used.

    Full Text Available What does the photography in contemporary visual culture? In the ever increasing interference between art and society, photography took over, as you can see, a leading role in what Enrico Menduni defines the process of "picture show", especially if it isconsidered in its close relationship with the advertising industry. However you cannot ignore the fact that, being closely bound to functions that is responsible, photography is also a social practice. These considerations have a concrete response in the contemporary art. Arturo Ghergo (1901-1959, Bob Richardson (1928-2005 and Bettina Rheims (1952 are artists with very different poetics that while making photographs on commission (for movies, advertising, fashion and magazines told through pictures their time (and the aspects of reality that have characterized reaching high and recognized results of artistic and aesthetic value. They are just three of the many photographers who put us in front of the hybrid status of photography as "a medium [...] inextricably linked to two aspects: aesthetic and sociological" (Dorfles 2012. Discussions on the border between photography-craft and photography-art, which long have marked and restricted the destiny of many photographers, today finally appear anachronistic, but not entirely overcome. We see more and more often a dissolution of identity between the two areas with important examples of the deep connection of the dichotomy between art and social aspects. If it is true that art has always told, interpreted and reflected on the reality that is part, what seems interesting to highlight is the fact that the impact on the collective imaginary that new visual media, photography in primis, have had and continue to have increasingly appears to have no background. Therefore, art has never been so close to life.

  5. Course review: the 4th Bob Huffstadt upper and lower limb flap dissection course. (United States)

    Dunne, Jonathan A


    The Bob Huffstadt course is a 2-day upper and lower limb flap dissection course held in Groningen, the Netherlands. The course is in English, with an international faculty of senior consultants from the Netherlands, Belgium, and United Kingdom. Faculty to participant ratio is 2:1, with 2 participants at each dissection table. The course is aimed at trainees in plastic surgery of all levels, and a comprehensive DVD is provided before the course, which demonstrates dissection of 35 flaps, ensuring those with little experience to have an understanding before dissection.This course offered a comprehensive overview with plenty of practical application. The course can greatly develop operative and theoretical knowledge, while also demonstrating a commitment for those wishing to pursue a career in plastic surgery. Longer courses are available; however, the 2-day course can already provide an excellent introduction for junior trainees. There are few flap courses in the United Kingdom and senior trainees may have difficulty acquiring a place as they book up well in advance. With reductions in operating time, trainees may welcome further experience and development of techniques in the dissection room.Most of both days were spent in the dissection room, raising flaps and receiving teaching from the faculty. Dissections included Foucher, Moberg, Becker, radial forearm, anterolateral thigh, and fibula flaps. Dissection specimens were fresh-frozen preparation, and 9 upper limb flaps were raised on the first day and 5 lower limb flaps on the second day. The faculty provided live demonstrations of perforator dissection, use of the hand-held Doppler, and tips and tricks. The last 2 hours of each day were spent with 2 lectures, including topics from the history of flaps and developments to challenging cases and reconstructive options.The course fee was 1000 euros, including a 5-course dinner, lunch on both days, and a drinks reception on the final evening. I would recommend this

  6. D-558-1 on ramp with ground crew and NACA pilot Bob Champine (United States)


    NACA test pilot Robert Champine is seen in the cockpit of the Douglas D-558-1 Skystreak with the ground crew. Robert A. Champine was a research pilot with the National Advisory Committee for Aeronautics (NACA) and the National Aeronautics and Space Administration (NASA) from December 1947 to 1979, when he retired as Langley Research Center's senior research pilot. He began his career with the NACA at the Langley Memorial Aeronautical Laboratory in Hampton, Virginia (as Langley Research Center was then called). He transferred to the NACA's High-Speed Flight Research Station in the Mojave Desert of California in October 1948, where he flew the X-1 and D-558-1 and -2 research airplanes. On December 2, 1948, Bob became the 6th man and 3rd civilian to break the mysterious sound barrier. He exceeded Mach 1 on NACA flight 23 checking handling qualities and pressure distribution on the XS-1 #2, after having been dropped from the B-29 mother ship, above the Rogers Dry Lake in California. On August 4, 1949, NACA flight 32, he again exceeded Mach 1 performing rolls, pullups, sideslips, and check of stabilizer effectiveness. This was his 13th and last flight in the XS-1. He flew the first NACA research flight of the D-558-1 #3 (Skystreak) on April 22, 1949, and the first NACA research flight of the D-558-2 #2 (Skyrocket) on May 24, 1949, beginning the supersonic research program for these aircraft on June l, 1949. Conceived in 1945, the D558-1 Skystreak was designed by the Douglas Aircraft Company for the U.S. Navy Bureau of Aeronautics, in conjunction with the National Advisory Committee for Aeronautics (NACA). The Skystreaks were turojet powered aircraft that took off from the ground under their own power and had straight wings and tails. All three D-558-1 Skystreaks were powered by Allison J35-A-11 turbojet engines producing 5,000 pounds of thrust. All the Skystreaks were initially painted scarlet, which lead to the nickname 'crimson test tube.' NACA later had the color of

    Bob Baron of the Dryden Flight Research Center (left) and Brian Anderson of the Johnson Space Flight Center (right) flank an X-38 prototype Crew Return Vehicle technology demonstrator under construction at the Johnson Space Center, Houston, Texas. The X-38 Crew Return Vehicle (CRV) research project is designed to develop the technology for a prototype emergency crew return vehicle, or lifeboat, for the International Space Station. The project is also intended to develop a crew return vehicle design that could be modified for other uses, such as a joint U.S. and international human spacecraft that could be launched on the French Ariane-5 Booster. The X-38 project is using available technology and off-the-shelf equipment to significantly decrease development costs. Original estimates to develop a capsule-type crew return vehicle were estimated at more than $2 billion. X-38 project officials have estimated that development costs for the X-38 concept will be approximately one quarter of the original estimate. Off-the-shelf technology is not necessarily 'old' technology. Many of the technologies being used in the X-38 project have never before been applied to a human-flight spacecraft. For example, the X-38 flight computer is commercial equipment currently used in aircraft and the flight software operating system is a commercial system already in use in many aerospace applications. The video equipment for the X-38 is existing equipment, some of which has already flown on the space shuttle for previous NASA experiments. The X-38's primary navigational equipment, the Inertial Navigation System/Global Positioning System, is a unit already in use on Navy fighters. The X-38 electromechanical actuators come from previous joint NASA, U.S. Air Force, and U.S. Navy research and development projects. Finally, an existing special coating developed by NASA will be used on the X-38 thermal tiles to make them more durable than those used on the space shuttles. The X-38 itself was an

  8. “The Low Hum in Syllables and Meters”: Blues Poetics in Bob Dylan’s Verbal Art

    Directory of Open Access Journals (Sweden)

    Catharine Mason


    Full Text Available Applying the linguistic category of style as put forth by Dell Hymes, this article seeks to identify the poetic devices borrowed by Bob Dylan from lyrics of traditional blues masters. The author highlights rhetorical form as it is connected to personal and cultural meaning in Blind Willie McTell’s “Broke Down Engine,” as recorded both by McTell and later by Dylan. Among the stylistic operations examined, we find a description of the phenomenon of songfulness as defined by Lawrence Kramer, metaphoric designs of Southern American English, expressive grammar deviations, and the syntactic formulation the author defines as “binary blues clauses,” commonly used in the AAB blues structure. The study is illustrated with a close analysis of language and genre use in Dylan’s “10,000 Men.”

    Directory of Open Access Journals (Sweden)

    Carolina Moreira Voloch


    Full Text Available The sea-bob shrimp, Xiphopenaeus kroyeri, is one of the most important economic marine resources along the entire Brazilian coast. Nevertheless, despite its economic importance, no studies have examined the population genetics of this species. In this paper, we used ten allozyme loci to study the pattern of genetic structuring in X. kroyeri along the southeastern Brazilian coast. Seven of the ten analyzed loci were polymorphic, yielding observed heterozygosity values higher than those reported for other penaeid shrimps. The population from São Paulo was significantly different from the other two populations (Rio de Janeiro and Espírito Santo, which, in turn, seem to form a single panmitic unit. Therefore, our results clearly indicate that conservation policies for this species should consider the São Paulo population as an independent stock from those of Rio de Janeiro and Espírito Santo.

    A new lithium salt(LiBOB) based on a chelated borate anion, BOB [Bis (oxalate) borate] was synthesized by an improved solid-state method and purified by rectification. Four different lithium-containing compounds were selected as lithium sources. The synthesized LiBOB was identified by infrared spectrum, X-ray diffraction(XRD) and quantitative chemical analysis. The effects of lithium sources on the purity and electrochemical performance of LiBOB products were investigated. The results show that the purity of LiBOB synthesized from LiOH.H2O is larger than 99.4% after one time of purification and larger than 99.8% after two times of purification. The LiBOB synthesized from Li2C2O4has impurity phases and that from CH3COOLi-2H2O has high water content. The lithium manganese dioxide button cell was assembled with 0.7 mol/L LiBOB/(EC:PC:DMC =1:1:3, mass ratio) as electrolyte and the cycle performance of the cell was tested. LiBOB with LiOHH2O or Li2CO3 as lithium sources shows better electrochemical performance while that with Li2C2O4 or CH3COOLi-2H2O as lithium sources shows poor electrochemical performance.%用改进的固相合成方法及精馏提纯方法,获得一种含有螯合硼酸根离子的电解质锂盐—双草酸硼酸锂(LiBOB).分别选取4种含锂化合物作为锂源,采用红外光谱、X线衍射方法和化学定量分析方法,比较不同锂源对合成LiBOB的产物纯度、电化学性能的影响.研究结果表明:由LiOH·H2O合成的粗产品1次纯化纯度为99.4%,2次纯化纯度为99.8%;由Li2C2O4合成的LiBOB杂相较多;由CH3COOLi.2H2O合成的LiBOB含水分较多.用不同锂源合成的LiBOB配制成0.7 mol/L LiBOB/(EC/PC/DMC=1∶1∶3,质量比)电解液,组装成LiM2O4/Li电池进行电池循环性能的测试.LiOH·H2O和Li2CO3作为锂源合成的LiBOB具有良好的电化学性能,Li2C2O4和CH3COOLi·2H2O作为锂源合成的LiBOB电化学性能较差.

  17. Homage to Bob Brodkey at 85: Ejections, Sweeps and Reynolds Shear Stress Generation in Turbulent Pipe Flow

    CERN Document Server

    Wallace, James M


    Almost 50 years ago Bob Brodkey and his student, Corino, conceived of and carried out a visualization experiment for the very near wall region of a turbulent pipe flow that, together with the turbulent boundary layer visualization of Kline et al., excited the turbulence research community. Using a high-speed movie camera mounted on a lathe bed that recorded magnified images in a frame of reference moving with the flow, they observed the motions of submicron particles in the sub-layer, buffer-layer and lower part of the log-layer. Surprisingly, these motions were not nearly so locally random as was the general view of turbulence at the time. Rather, connected regions of the near wall flow decelerated and then erupted away from the wall in what they called "ejections". These decelerated motions were followed by larger scale connected motions toward the wall from above that they called "sweeps". They estimated that ejections accounted for 70% of the Reynolds shear stress at Re_d = 20,000 while only occurring abo...

  18. B fields in OB stars (BOB): low-resolution FORS2 spectropolarimetry of the first sample of 50 massive stars

    Within the context of the collaboration "B fields in OB stars (BOB)", we used the FORS2 low-resolution spectropolarimeter to search for a magnetic field in 50 massive stars, including two reference magnetic massive stars. Because of the many controversies of magnetic field detections obtained with the FORS instruments, we derived the magnetic field values with two completely independent reduction and analysis pipelines. We compare and discuss the results obtained from the two pipelines. We obtained a general good agreement, indicating that most of the discrepancies on magnetic field detections reported in the literature are caused by the interpretation of the significance of the results (i.e., 3-4 sigma detections considered as genuine, or not), instead of by significant differences in the derived magnetic field values. By combining our results with past FORS1 measurements of HD46328, we improve the estimate of the stellar rotation period, obtaining P = 2.17950+/-0.00009 days. For HD125823, our FORS2 measurem...

  20. B-cell transcription factors Pax-5, Oct-2, BOB.1, Bcl-6, and MUM1 are useful markers for the diagnosis of nodular lymphocyte predominant Hodgkin lymphoma. (United States)

    Herbeck, Rosemarie; Teodorescu Brînzeu, D; Giubelan, Marioara; Lazăr, Elena; Dema, Alis; Ioniţă, Hortensia


    In some instances, the overlap in morphologic features and antigen expression between nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and classical Hodgkin lymphoma (cHL) can cause confusion in the diagnosis. In these cases, the transcription factors (TFs) B-cell specific activator protein (BSAP)/Pax-5, octamer binding protein-2 (Oct-2), B-lymphocyte-specific co-activator BOB.1/OBF.1, Bcl-6 protein and multiple myeloma-1/interferon regulatory factor-4 (MUM1/IRF-4) may aid in clarifying the diagnosis. Twenty-two cases of NLPHL were studied for the immunohistochemical expression of Pax-5, Oct-2, BOB.1, Bcl-6 protein and MUM1/IRF-4. Our results sustain the usefulness of the selected set of TFs to diagnose and distinguish NLPHL from cHL since Pax-5, Oct-2, BOB.1 and Bcl-6 are consistently expressed by lymphocyte predominant (LP) cells and reported by others to be often unexpressed in Hodgkin and Reed-Sternberg cells. By contrast, MUM1/IRF-4 protein scored negative in the majority of LP cells, but is reported to be expressed in almost all cases of cHL. Thus, although the expression of transcription factors is very heterogeneous, their simultaneous implementation for positive and differential diagnosis may be useful.

    OCT-2 and its co-activator, BOB.1, are B-cell associated transcription factors expressed in a subset of patients with acute myeloid leukemia (AML). We evaluated OCT-2 and BOB.1 expression by immunohistochemistry in patients with newly diagnosed AML. The median overall survival (OS) for patients with varying levels of OCT-2 expression was statistically different (p = 0.03) (OCT-2 50%: 11.6 months). On multivariate analysis, co-expression of OCT-2/BOB.1 remained predictive for achievement of complete remission (HR 0.44, p = 0.010) and increased risk of relapse (HR 2.30, p = 0.047). OCT-2 (per 10% increase) was associated with a decreased progression-free survival (HR 1.10, p = 0.036) and a trend toward a worse OS (HR 1.10, p = 0.063). OCT-2 may act as a cell survival factor in AML by mediating expression of downstream targets, such as BCL-2. These results will need to be validated prospectively.

  5. From the Bob/Kirk effect to the Benoit/Éric effect: Testing the mechanism of name sound symbolism in two languages. (United States)

    Sidhu, David M; Pexman, Penny M; Saint-Aubin, Jean


    Although it is often assumed that language involves an arbitrary relationship between form and meaning, many studies have demonstrated that nonwords like maluma are associated with round shapes, while nonwords like takete are associated with sharp shapes (i.e., the Maluma/Takete effect, Köhler, 1929/1947). The majority of the research on sound symbolism has used nonwords, but Sidhu and Pexman (2015) recently extended this effect to existing labels: real English first names (i.e., the Bob/Kirk effect). In the present research we tested whether the effects of name sound symbolism generalize to French speakers (Experiment 1) and French names (Experiment 2). In addition, we assessed the underlying mechanism of name sound symbolism, investigating the roles of phonology and orthography in the effect. Results showed that name sound symbolism does generalize to French speakers and French names. Further, this robust effect remained the same when names were presented in a curved vs. angular font (Experiment 3), or when the salience of orthographic information was reduced through auditory presentation (Experiment 4). Together these results suggest that the Bob/Kirk effect is pervasive, and that it is based on fundamental features of name phonemes.

  6. Phospholipase C mediates (±)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI)-, but not lysergic acid diethylamide (LSD)-elicited head bobs in rabbit medial prefrontal cortex. (United States)

    Schindler, Emmanuelle A D; Harvey, John A; Aloyo, Vincent J


    The phenethylamine and indoleamine classes of hallucinogens demonstrate distinct pharmacological properties, although they share a serotonin(2A) (5-HT(2A)) receptor mechanism of action (MOA). The 5-HT(2A) receptor signals through phosphatidylinositol (PI) hydrolysis, which is initiated upon activation of phospholipase C (PLC). The role of PI hydrolysis in the effects of hallucinogens remains unclear. In order to better understand the role of PI hydrolysis in the MOA of hallucinogens, the PLC inhibitor, 1-[6-((17β-3-methoxyestra-1,3,5(10)-trien-17-yl)amino)hexyl]-1H-pyrrole-2,5-dione (U73122), was used to study the effects of two hallucinogens, the phenethylamine, (±)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI), and the indoleamine, lysergic acid diethylamide (LSD). PI hydrolysis was quantified through release of [3H]inositol-4-phosphate from living rabbit frontocortical tissue prisms. Head bobs were counted after hallucinogens were infused into the medial prefrontal cortex (mPFC) of rabbits. Both DOI and LSD stimulated PI hydrolysis in frontocortical tissue through activation of PLC. DOI-stimulated PI hydrolysis was blocked by 5-HT(2A/2C) receptor antagonist, ketanserin, whereas the LSD signal was blocked by 5-HT(2B/2C) receptor antagonist, SB206553. When infused into the mPFC, both DOI- and LSD-elicited head bobs. Pretreatment with U73122 blocked DOI-, but not LSD-elicited head bobs. The two hallucinogens investigated were distinct in their activation of the PI hydrolysis signaling pathway. The serotonergic receptors involved with DOI and LSD signals in frontocortical tissue were different. Furthermore, PLC activation in mPFC was necessary for DOI-elicited head bobs, whereas LSD-elicited head bobs were independent of this pathway. These novel findings urge closer investigation into the intracellular mechanism of action of these unique compounds.

  7. A Face like a Mask and a Voice that Croaks: An Integrated Poetics of Bob Dylan’s Voice, Personae, and Lyrics

    Directory of Open Access Journals (Sweden)

    Christophe Lebold


    Full Text Available This article seeks to examine the literary pleasures derived from Bob Dylan’s songs, paying special attention to how Dylan’s poetical texts are performed and rhythmically rewritten by his voice, as well as the ways in which Dylan uses the songs to “write himself” through the creation of numerous and competing *personae*. Close reading of the lyrics, this article argues, must therefore be supplemented by a “poetics of the voice” and a detailed analysis of the theatricality of his “games of masks.” While a stylistic approach to the lyrics reveals a thrust towards *writerly* openness and new poetical idioms that fuse oral traditions with high poetry, the aesthetic and semantic uses Dylan makes of his voice are equally sophisticated. A study of Dylan’s “masks” will show that the artist uses archetypal poetic identities (prophet, trickster, man of sorrow, and so on as fictional figurations of himself offered to the audience.

    Within the context of the "B fields in OB stars (BOB)" collaboration, we used the HARPSpol spectropolarimeter to observe the early B-type stars beta CMa (HD44743; B1 II/III) and epsilon CMa (HD52089; B1.5 II). For both stars, we consistently detected the signature of a weak (<30 G in absolute value) longitudinal magnetic field. We determined the physical parameters of both stars and characterise their X-ray spectrum. For beta CMa, our mode identification analysis led to determining a rotation period of 13.6+/-1.2 days and of an inclination angle of the rotation axis of 57.6+/-1.7 degrees, with respect to the line of sight. On the basis of these measurements and assuming a dipolar field geometry, we derived a best fitting obliquity of ~22 degrees and a dipolar magnetic field strength (Bd) of ~100 G (60

  9. In tribute to Bob Blanchard: Divergent behavioral phenotypes of 16p11.2 deletion mice reared in same-genotype versus mixed-genotype cages. (United States)

    Yang, Mu; Lewis, Freeman; Foley, Gillian; Crawley, Jacqueline N


    Mouse models offer indispensable heuristic tools for studying genetic and environmental causes of neuropsychiatric disorders, including autism. Development of useful animal models of complex human behaviors depends not only on extensive knowledge of the human disease, but also on a deep understanding of animal behavior and ethology. Robert and Caroline Blanchard pioneered a number of elegant social paradigms in rodents. Their early work led to systematic delineations of rodent naturalist defensive behaviors,which were proven to be highly useful models of human psychiatric disorders, including fear and anxiety. Their work using the Visible Burrow System to study social stress in rats represented an unprecedented approach to study biological mechanisms of depression. In recent years, their extensive knowledge of mouse behavior and ethology enabled them to quickly become leading figures in the field of behavioral genetics of autism. To commemorate Robert Blanchard's influences on animal models of human psychiatric disorders, here we describe a study conceptualized and led by Mu Yang who was trained as a graduate student in the Blanchard laboratory in the early 2000s. This investigation focuses on social housing in a genetic mouse model of 16p11.2 deletion syndrome. Heterozygous deletions and duplications of a segment containing about 29 genes on human chromosome 16 appear in approximately 0.5–1% of all cases of autism. 16p11.2 deletion syndrome is also associated with intellectual disabilities and speech impairments. Our previous studies showed that a mouse model of 16p11.2 deletion syndrome exhibited deficits in vocalizations and novel object recognition, as compared to wildtype littermate control cagemates. In the spirit of Bob Blanchard's careful attention to the role of social dominance in rodent behaviors, we became interested in the question of whether behavioral outcomes of a mutation differ when mutants are housed in mixed genotype cages, versus housing only

  10. Hot topic: investigating the risk of violative meat residues in bob veal calves fed colostrum from cows treated at dry-off with cephapirin benzathine. (United States)

    Hausler, K; Godden, S M; Schneider, M J; Lightfield, A R; Bulthaus, M; Haines, D


    The objective was to conduct a study to investigate if violative meat residues are detected in very young bob veal calves that are fed first-milking colostrum harvested from cows that were dry treated, on-label, with cephapirin benzathine. First-milking colostrum was collected from cows that were given intramammary treatment at dry off, on-label, with cephapirin benzathine (ToMORROW, Boehringer Ingelheim Vetmedica Inc., St. Joseph, MO). Newborn bull calves meeting study inclusion criteria were removed from their dams shortly after birth and before suckling, and assigned to 1 of 2 trials. For the first trial, 6 treated calves were fed 3.8L of fresh maternal colostrum and 1 control calf was fed 1.5 doses of a plasma-derived colostrum replacer (Secure Calf Colostrum Replacer, VitaPlus Inc., Madison, WI) within 1h after birth. For the second trial, 5 treated calves were fed 3.8L of fresh maternal colostrum and 1 control calf was fed 1.5 doses of Secure Calf Colostrum Replacer within 1h after birth. All calves were humanely euthanized at 24h (trial 1) or 48h (trial 2) of age, and tissues were harvested for antimicrobial residue testing. Samples of maternal colostrum and colostrum replacer were also submitted for antimicrobial residue testing. Kidneys collected from all study calves tested negative for cephapirin benzathine residues when using both the KIS assay (Charm Sciences, Lawrence, MA) and liquid chromatography-tandem mass spectrometry analysis. The potential transfer of cephapirin from cows treated on-label at dry off to calves via colostrum may not be a significant source of cephapirin residues in veal tissues.

  16. Evaluating the Efficacy of Three U.S. Department of Agriculture-Approved Antimicrobial Sprays for Reducing Shiga Toxin-Producing Escherichia coli Surrogate Populations on Bob Veal Carcasses. (United States)


    Effective antimicrobial intervention strategies to reduce Shiga toxin-producing Escherichia coli (STEC) risks associated with veal are needed. This study evaluated the efficacy of lactic acid (4.5%, pH 2.0), Citrilow (pH 1.2), and Beefxide (2.25%, pH 2.3) for reducing STEC surrogates on prerigor and chilled bob veal carcasses and monitored the effects of these interventions on chilled carcass color. Dehided bob veal carcasses were inoculated with a five-strain cocktail of rifampin-resistant, surrogate E. coli bacteria.E. coli surrogates were enumerated after inoculation, after water wash, after prechill carcass antimicrobial spray application, after chilling for 24 h, and after postchill carcass antimicrobial spray application; carcass color was measured throughout the process. A standard carcass water wash (∼50°C) reduced the STEC surrogate population by 0.9 log CFU/cm(2) (P ≤ 0.05). All three antimicrobial sprays applied to prerigor carcasses delivered an additional ∼0.5-log reduction (P ≤ 0.05) of the surrogates. Chilling of carcasses for 24 h reduced (P ≤ 0.05) the surrogate population by an additional ∼0.4 log cycles. The postchill application of the antimicrobial sprays provided no further reductions. Carcass L*, a*, and b* color values were not different (P > 0.05) among carcass treatments. Generally, the types and concentrations of the antimicrobial sprays evaluated herein did not negatively impact visual or instrumental color of chilled veal carcasses. This study demonstrates that warm water washing, followed by a prechill spray treatment with a low-pH chemical intervention, can effectively reduce STEC risks associated with veal carcasses; this provides processors a validated control point in slaughter operations.

  19. The complete mitochondrial genomes of deep-sea squid (Bathyteuthis abyssicola), bob-tail squid (Semirossia patagonica) and four giant cuttlefish (Sepia apama, S. latimanus, S. lycidas and S. pharaonis), and their application to the phylogenetic analysis of Decapodiformes. (United States)

    Kawashima, Yuumi; Nishihara, Hidenori; Akasaki, Tetsuya; Nikaido, Masato; Tsuchiya, Kotaro; Segawa, Susumu; Okada, Norihiro


    We determined the complete mitochondrial (mt) genomes of the deep-sea squid (Bathyteuthis abyssicola; supperfamily Bathyteuthoidea), the bob-tail squid (Semirossia patagonica; order Sepiolida) and four giant cuttlefish (Sepia apama, S. latimanus, S. lycidas and S. pharaonis; order Sepiida). The unique structures of the mt genomes of Bathyteuthis and Semirossia provide new information about the evolution of decapodiform mt genomes. We show that the mt genome of B. abyssicola, like those of other oegopsids studied so far, has two long duplicated regions that include seven genes (COX1-3, ATP6 and ATP8, tRNA(Asn), and either ND2 or ND3) and that one of the duplicated COX3 genes has lost its function. The mt genome of S. patagonica is unlike any other decapodiforms and, like Nautilus, its ATP6 and ATP8 genes are not adjacent to each other. The four giant cuttlefish have identical mt gene order to other cuttlefish determined to date. Molecular phylogenetic analyses using maximum likelihood and Bayesian methods suggest that traditional order Sepioidea (Sepiolida+Sepiida) is paraphyletic and Sepia (cuttlefish) has the sister-relationship with all other decapodiforms. Taking both the phylogenetic analyses and the mt gene order analyses into account, it is likely that the octopus-type mt genome is an ancestral state and that it had maintained from at least the Cephalopoda ancestor to the common ancestor of Oegopsida, Myopsida and Sepiolida.

    Full Text Available A pesca artesanal do camarão sete-barbas é denominada "pesca de sol a sol" e realizada em grande escala no litoral brasileiro, apresentando uma significativa importância econômica, histórica, social e cultural. Atualmente, a pesca desse camarão é considerada a de maior interesse econômico e o segundo recurso pesqueiro nas regiões Sudeste-Sul do Brasil. Com o objetivo de estudar a biologia e pesca do camarão sete-barbas na Armação do Itapocoroy, Penha (26º40'-26º47'S e 48º36'-48º38'W, durante o período de agosto de 1996 a julho de 2003 foram realizadas coletas mensais com 30 minutos de duração. Foram registrados o número e a biomassa dos exemplares por arrasto, e entre anos de 1996-1997 e 1999-2001, também foram anotados o sexo, o comprimento e peso total, estádio de maturação. Além dessas informações, entre agosto de 1998 a julho de 1999 foi analisado a dieta natural da espécie. X. kroyeri (Heller, 1862 apresentou comprimento total variando entre 3,0 e 16,0 cm e flutuações sazonais na abundância e biomassa, com as maiores taxas de captura ocorreram durante os meses de verão e outono.

    Full Text Available A ictiofauna acompanhante na pesca de camarão sete-barbas foi estudada mensalmente entre agosto 1996 a julho 2003 nas áreas de atuação da pesca artesanal na Armação do Itapocoroy, Penha. Foram utilizadas duas redes-de-arrasto com portas, malha de 3,0 cm na manga e corpo e de 2,0 cm no ensacador, tracionada por baleeira com velocidade média de 2,0 nós. A temperatura e salinidade média da água de fundo mantiveram um padrão uniforme de flutuação sazonal, sem diferença significativa entre os anos de coleta. Das 60 espécies capturadas, 22 foram comuns ao longo do período de coleta. As famílias Sciaenidae, Carangidae e Clupeidae apresentaram o maior número de espécies contribuindo com 92,0% das capturas, onde Stellifer spp., Paralonchurus brasiliensis e Isopisthus parvipinnis foram mais abundantes nas coletas, apresentando ocorrência regular ao longo dos anos. Ocorreram flutuações sazonais na abundância e diversidade da ictiofauna com diferença significativa entre os anos de coleta e biomassa, bem como em número de exemplares. O monitoramento da pesca de arrasto direcionada ao camarão sete-barbas poderá contribuir na manutenção dos estoques e assegurar a subsistência das comunidades tradicionais no litoral catarinense.The ichthyofauna bycatch in sea-bob-shrimp's fishery was monthly studied from August 1996 to July 2003, in the artisanal fishing grounds at Armação do Itapocoroy, Penha.

    Secure key distribution among classical parties is impossible both between two parties and in a network. In this paper, we present a quantum key distribution (QKD) protocol to distribute secure key bits among one quantum party and numerous classical parties who have no quantum capacity. We prove that our protocol is completely robust, i.e.,any eavesdropping attack should be detected with nonzero probability. Our calculations show that our protocol may be secure against Eve's symmetrically individual attack.

  3. Vocal Performance and Speech Intonation: Bob Dylan’s “Like a Rolling Stone”

    Directory of Open Access Journals (Sweden)

    Michael Daley


    Full Text Available This article proposes a linguistic analysis of a recorded performance of a single verse of one of Dylan’s most popular songs—the originally released studio recording of “Like A Rolling Stone”—and describes more specifically the ways in which intonation relates to lyrics and performance. This analysis is used as source material for a close reading of the semantic, affective, and “playful” meanings of the performance, and is compared with some published accounts of the song’s reception. The author has drawn on the linguistic methodology formulated by Michael Halliday, who has found speech intonation (which includes pitch movement, timbre, syllabic rhythm, and loudness to be an integral part of English grammar and crucial to the transmission of certain kinds of meaning. Speech intonation is a deeply-rooted and powerfully meaningful aspect of human communication. This article argues that is plausible that a system so powerful in speech might have some bearing on the communication of meaning in sung performance.

  13. Alice Meets Bob: A Comparative Usability Study of Wireless Device Pairing Methods for a "Two-User" Setting

    CERN Document Server

    Kumar, Arun; Uzun, Ersin


    When users want to establish wireless communication between/among their devices, the channel has to be bootstrapped first. To prevent any malicious control of or eavesdropping over the communication, the channel is desired to be authenticated and confidential. The process of setting up a secure communication channel between two previously unassociated devices is referred to as "Secure Device Pairing". When there is no prior security context, e.g., shared secrets, common key servers or public key certificates, device pairing requires user involvement into the process. The idea usually involves leveraging an auxiliary human-perceptible channel to authenticate the data exchanged over the insecure wireless channel. We observe that the focus of prior research has mostly been limited to pairing scenarios where a single user controls both the devices. In this paper, we consider more general and emerging "two-user" scenarios, where two different users establish pairing between their respective devices. Although a num...

  15. Working to Design: The Self-Perpetuating Ideology of Rock or ... ‘The New Bob Dylan’

    Directory of Open Access Journals (Sweden)

    John Scannell


    Full Text Available This premise of this article is that music and the writing process have no inherent kinship, and that the often ill-conceived merger of these activities as the “music writing” process, is generally destined for failure. That is because writing about music subsumes its affective power into a foreign modality; it is captured and rendered into the printed word, made to signify, made to represent something, where that something is generally resolved within the presuppositions of the writers’ often-limited referential framework. At the heart of the matter is that writing about music often does not attempt to capture the affective processes that inspired creation in the first place, and in this respect, the paper argues that it may be more appropriate for the music writer/journalist to respond in kind, or as Deleuze and Guattari might say, that the music writing process should pursue a ‘becoming-music’ itself. For rather than subjecting music to the realm of representation, or subsuming its creative power within the realm of opinion and cliché, the writer should instead be concerned with harnessing and re-channelling those forces of sensation or affect that gave rise to it in the first place, and which might, in turn, inspire a literary creativity that is commensurate to the power of the music at hand.

  20. Seismic Imaging and Inversion: Application of Linear Theory (2012), Cambridge University Press, co-authored with Bob Stolt

    Energy Technology Data Exchange (ETDEWEB)

    Weglein, Arthur B.; Stolt, Bob H.


    Extracting information from seismic data requires knowledge of seismic wave propagation and reflection. The commonly used method involves solving linearly for a reflectivity at every point within the Earth, but this book follows an alternative approach which invokes inverse scattering theory. By developing the theory of seismic imaging from basic principles, the authors relate the different models of seismic propagation, reflection and imaging - thus providing links to reflectivity-based imaging on the one hand and to nonlinear seismic inversion on the other. The comprehensive and physically complete linear imaging foundation developed presents new results at the leading edge of seismic processing for target location and identification. This book serves as a fundamental guide to seismic imaging principles and algorithms and their foundation in inverse scattering theory and is a valuable resource for working geoscientists, scientific programmers and theoretical physicists.

  1. Versatility of continuous-variable asymmetric tripartite entanglement allows Alice and Clare to keep secrets from Bob (United States)

    Olsen, M. K.; Cavalcanti, E. G.


    The fully symmetric Gaussian tripartite entangled pure states will not exhibit two-mode Einstein-Podolsky-Rosen (EPR) steering. This means that any two participants cannot share quantum secrets using the security of one-sided device independent quantum key distribution (1SDI-QKD) without involving the third. They are restricted at most to standard quantum key distribution, which is less secure. Here we demonstrate an asymmetric tripartite system that can exhibit bipartite EPR steering, so that two of the participants can use 1SDI-QKD without involving the other. This is possible because the promiscuity relations of continuous-variable tripartite entanglement are different from those of discrete-variable systems. We analyze these properties for two different systems, showing that the asymmetric system exhibits practical properties not found in the symmetric one.

  2. Management of Barrett esophagus: a practical guide for clinicians based on the BADCAT and BoB CAT recommendations. (United States)

    Jankowski, Jakob; Bennett, Cathy; Jankowski, Janusz A


    We undertook two of the largest evidence-based reviews in clinical medicine to assess the rationale for the management of gastroesophageal reflux disease, Barrett esophagus (BE), dysplasia, and early invasive esophageal adenocarcinoma. These reviews involved over 150 world experts in 4 continents, and over 20 000 papers were assessed. Quality assessment of the publications was made using Grading of Recommendations Assessment, Development and Evaluation, and of over 240 questions formulated, we were able to answer 30% with an agreement of at least 80%. We agreed on a unique global definition of BE meaning that the presence both of hiatus hernia endoscopically and of intestinal metaplasia histologically should be noted. In addition, we devised an escalation and deescalation pathway for the management of esophagitis, metaplasia, dysplasia, and adenocarcinoma sequence. Endoscopic resection (ER) is recommended for visible mucosal lesions. Moreover, we endorsed the early use of ablation therapy for persistent dysplasia of any degree. In this regard, ER may be both diagnostic and therapeutic and may be sufficient even in early mucosal lesions (T1m). In conclusion, fewer people should be surveyed but those that do will require more detailed mapping and endoscopic interventions than currently. In addition, patients accumulating other potentially life-threaten-ing comorbidities should be offered cessation of surveillance. In the future, chemoprevention may be the game-changing solution but results from large randomized trials, including AspECT and BOSS, are awaited.

  3. B fields in OB stars (BOB): The magnetic triple stellar system HD 164492C in the Trifid nebula (United States)

    HD 164492C is a spectroscopic triple stellar system that has been recently detected to possess a strong magnetic field. We have obtained high-resolution spectroscopic and spectropolarimetric observations over a timespan of two years and derived physical, chemical, and magnetic properties for this object. The system is formed by an eccentric close spectroscopic binary (Ca1-Ca2) with a period of 12.5 days, and a massive tertiary Cb. We calculated the orbital parameters of the close pair, reconstructed the spectra of the three components, and determined atmospheric parameters and chemical abundances by spectral synthesis. From spectropolarimetric observations, multi-epoch measurements of the longitudinal magnetic fields were obtained. The magnetic field is strongly variable on timescales of a few days, with a most probable period in the range of 1.4-1.6 days. Star Cb with Teff ˜ 25 000 K is the apparently fastest rotator and the most massive star of this triple system and has anomalous chemical abundances with a marked overabundance of helium, 0.35±0.04 by number. We identified this star as being responsible for the observed magnetic field, although the presence of magnetic fields in the components of the Ca pair cannot be excluded. Star Ca1 with a temperature of about 24 000 K presents a normal chemical pattern, while the least massive star Ca2 is a mid-B type star (Teff ˜ 15 000 K) with an overabundance of silicon. The obtained stellar parameters of the system components suggest a distance of 1.5 kpc and an age of 10-15 Myr.

  4. Langerhans cell histiocytosis is a neoplasm and consequently its recurrence is a relapse: In memory of Bob Arceci. (United States)

    Egeler, R Maarten; Katewa, Satyendra; Leenen, Pieter J M; Beverley, Peter; Collin, Matthew; Ginhoux, Florent; Arceci, Robert J; Rollins, Barrett J


    Langerhans cell histiocytosis (LCH) remains a poorly understood disorder with heterogeneous clinical presentations characterized by focal or disseminated lesions that contain excessive CD1a+ langerin+ cells with dendritic cell features known as "LCH cells." Two of the major questions investigated over the past century have been (i) the origin of LCH cells and (ii) whether LCH is primarily an immune dysregulatory disorder or a neoplasm. Current opinion is that LCH cells are likely to arise from hematopoietic precursor cells, although the stage of derailment and site of transformation remain unclear and may vary in patients with different extent of disease. Over the years, evidence has provided the view that LCH is a neoplasm. The demonstration of clonality of LCH cells, insufficient evidence alone for neoplasia, is now bolstered by finding driver somatic mutations in BRAF in up to 55% of patients with LCH, and activation of the RAS-RAF-MEK-ERK (where MEK and ERK are mitogen-activated protein kinase and extracellular signal-regulated kinase, respectively) pathway in nearly 100% of patients with LCH. Herein, we review the evidence that recurrent genetic abnormalities characterized by activating oncogenic mutations should satisfy prerequisites for LCH to be called a neoplasm. As a consequence, recurrent episodes of LCH should be considered relapsed disease rather than disease reactivation. Mapping the complete genetic landscape of this intriguing disease will provide additional support for the conclusion that LCH is a neoplasm and is likely to provide more potential opportunities for molecularly targeted therapies.

    We report the detection of a magnetic field in the helium-strong star CPD-57 3509 (B2 IV), a member of the Galactic open cluster NGC3293, and characterise the star's atmospheric and fundamental parameters. Spectropolarimetric observations with FORS2 and HARPSpol are analysed using two independent approaches to quantify the magnetic field strength. A high-S/N FLAMES/GIRAFFE spectrum is analysed using a hybrid non-LTE model atmosphere technique. Comparison with stellar evolution models constrains the fundamental parameters of the star. We obtain a firm detection of a surface averaged longitudinal magnetic field with a maximum amplitude of about 1 kG. Assuming a dipolar configuration of the magnetic field, this implies a dipolar field strength larger than 3.3 kG. Moreover, the large amplitude and fast variation (within about 1 day) of the longitudinal magnetic field implies that CPD-57 3509 is spinning very fast despite its apparently slow projected rotational velocity. The star should be able to support a centr...

    Healthcare is considered a service profession and most of what clinicians do is manage information. Thus, information is not a necessary adjunct to care. It is care and effective patient management that require effective management of patients' clinical data. This perspective is supported by the World Health Organisation in its use of the quotation from Gonzalo Vecina Neto, head of the Brazilian National Health Regulatory Agency, 'There is no health without management, and there is no management without information'. This opinion paper discusses how traditional clinical decision-making led 'by the doctor' is unsustainable in the modern era and how e-technologies will facilitate distributed effective decision-making and new divisions of labour across the health workforce.

  11. Concrete poetry in England and Scotland 1962-75: Ian Hamilton Finlay, Edwin Morgan, Dom Sylvester Houédard and Bob Cobbing


    Thomas, Gregory Charles


    This thesis examines concrete poetry in England and Scotland from 1962 to 1975. Through the 1950s-70s, international concrete poetry evolved away from constructivist influenced, “classical” ideals of minimalism and iconic visual effect towards principles owing more to Dadaism and Futurism: spontaneity, maximalism, sonority and an emphasis on intermedial expression. Against this backdrop, using close textual analysis supported by primary research, I engage with four poets whose ...

    Massive B-type stars with strong magnetic fields and fast rotation are very rare and provide a mystery for theories of both star formation and magnetic field evolution. Only two such stars, called sigma Ori E analogs, were previously known. Recently, a team involved in APOGEE, one of the Sloan Digital Sky Survey III programs, announced the discovery of two additional rigidly rotating magnetosphere stars, HD23478 and HD345439. The presence of magnetic fields in these newly discovered sigma Ori E analogs was not investigated in the past. In the framework of our ESO Large Programme, and one normal ESO programme, we carried out low-resolution FORS2 spectropolarimetric observations of HD23478 and HD345439. From the measurements using hydrogen lines, we discover a rather strong longitudinal magnetic field of the order of up to 1.5kG in HD23478, and up to 1.3kG using the entire spectrum. The analysis of HD345439 using four subsequent spectropolarimetric subexposures does not reveal the presence of a magnetic field a...

    Aims: Massive B-type stars with strong magnetic fields and fast rotation are very rare and pose a mystery for theories of star formation and magnetic field evolution. Only two such stars, called σ Ori E analogues, were known until recently. A team involved in APOGEE, one of the Sloan Digital Sky Survey III programs, announced the discovery of two additional rigidly rotating magnetosphere stars, HD 23478 and HD 345439. The magnetic fields in these newly discovered σ Ori E analogues have not been investigated so far. Methods: In the framework of our ESO Large Programme and one normal ESO programme, we carried out low-resolution FORS 2 spectropolarimetric observations of HD 23478 and HD 345439. Results: In the measurements of hydrogen lines, we discover a rather strong longitudinal magnetic field of up to 1.5 kG in HD 23478 and up to 1.3 kG using the entire spectrum. The analysis of HD 345439 using four subsequent spectropolarimetric subexposures does not reveal a magnetic field at a significance level of 3σ. On the other hand, individual subexposures indicate that HD 345439 may host a strong magnetic field that rapidly varies over 88 min. The fast rotation of HD 345439 is also indicated by the behaviour of several metallic and He i lines in the low-resolution FORS 2 spectra that show profile variations already on this short time-scale. Based on observations obtained in the framework of the ESO Prgs. 191.D-0255(E) and 094.D-0355(B).Appendix A is available in electronic form at

  15. B field in OB stars (BOB): The outstandingly strong magnetic field in the evolved He-strong star CPD -62° 2124 (United States)

    The origin and evolution of magnetism in OB stars is far from being well understood. With approximately 70 magnetic OB stars known, any new object with unusual characteristics may turn out to be a key piece of the puzzle. We report the detection of an exceptionally strong magnetic field in the He-strong B2IV star CPD -62° 2124. Spectropolarimetric FORS2 and HARPSpol observations were analysed by two independent teams and procedures, concluding on a strong longitudinal magnetic field of approximately 5.2 kG. The quantitative characterisation of the stellar atmosphere yields an effective temperature of 23 650 ± 250 K, a surface gravity of 3.95 ± 0.10 dex and a surface helium fraction of 0.35 ± 0.02 by number. The metal composition is in agreement with the cosmic abundance standard, except for Mg, Si and S, which are slightly non-solar. The strong and broad ( 300 km s-1) disc-like emission displayed by the Hα line suggests a centrifugal magnetosphere supported by the strong magnetic field. Our results imply that CPD -62° 2124 is an early B-type star hosting one of the strongest magnetic fields discovered to date, and one of the most evolved He-strong stars known, with a fractional main-sequence lifetime of approximately 0.6. Based on observations made with ESO telescopes at the La Silla and Paranal observatories under programme ID 191.D-0255(G,I).

    The number of magnetic stars detected among massive stars is small; nevertheless, the role played by the magnetic field in stellar evolution cannot be disregarded. Links between line profile variability, enhancements/depletions of surface chemical abundances, and magnetic fields have been identified for low-mass B-stars, but for the O-type domain this is almost unexplored. Based on FORS2 and HARPS spectropolarimetric data, we present the first detection of a magnetic field in HD54879, a single slowly rotating O9.7 V star. Using two independent and different techniques we obtained the firm detection of a surface average longitudinal magnetic field with a maximum amplitude of about 600 G, in modulus. A quantitative spectroscopic analysis of the star with the stellar atmosphere code FASTWIND results in an effective temperature and a surface gravity of 33000$\\pm1000$ K and 4.0$\\pm0.1$ dex. The abundances of carbon, nitrogen, oxygen, silicon, and magnesium are found to be slightly lower than solar, but compatible ...

  20. PCB-Based Break-Out Box (United States)

    Lee, Jason H.


    Break-out boxes (BOBs) are necessary for all electrical integration/cable checkouts and troubleshooting. Because the price of a BOB is high, and no work can be done without one, often the procedure stops, simply waiting for a BOB. A less expensive BOB would take less time in the integration, testing, and troubleshooting process. The PCB-based BOB works and looks the same as a standard JPL BOB, called Gold Boxes. The only differences between the old BOB and the new PCB-based BOB is that the new one has 80 percent of its circuitry in a printed circuit board. This process reduces the time for fabrication, thus making the BOBs less expensive. Moreover, because of its unique design, the new BOBs can be easily assembled and fixed. About 80 percent of the new PCB-based BOB is in a $22 (at the time of this reporting) custom-designed, yet commercially available PCB. This device has been used successfully to verify that BOB cables were properly made. Also, upon completion, the BOB was beeped out via a multimeter to ensure that all sockets on the connectors were properly connected to the respective banana jack. When compared to the Gold Box BOBs, the new BOB has many advantages. It is much more cost efficient, it delivers equal usability at substantially lower cost of the BOB, and the Gold Box is much heavier when compared to the new BOB. The new BOB is also a bit longer and much more versatile in that connectors are easily changeable and if a banana jack is broken, it can be replaced instead of throwing away an entire BOB.

  10. Quantum Information Splitting of Arbitrary Three-qubit State by Using Five-qubit Cluster state and GHZ-state (United States)

    Yin, Aihan; Wang, Jiwei


    In this paper, a new scheme of quantum information splitting (8QIS) by using five-qubit state and GHZ-state as quantum channel is proposed. The sender Alice performs Bell-state measurements (BSMs) on her qubit-pairs respectively,then tells her measurement result to the receivers Bob. If Bob wants to reconstruct the original states, he must cooperates with the controller Charlie, that Charlie performs two single particle measurement on his qubits and tells Bob the results. According to Alice's and Bob's results, Bob can reconstruct the initial state by applying appropriate unitary operation.

  11. Gaussian quantum steering and its asymmetry in curved spacetime

    We study Gaussian quantum steering and its asymmetry in the background of a Schwarzschild black hole. We present a Gaussian channel description of quantum state evolution under the influence of Hawking radiation. We find that thermal noise introduced by Hawking effect will destroy the steerability between an inertial observer Alice and an accelerated observer Bob who hovers outside an event horizon, while it generates steerability between Bob and a hypothetical observer Anti-Bob inside the event horizon. Besides, unlike entanglement behaviors in curved spacetime, here the steering from Alice to Bob suffers from a ``sudden death" and the steering from Anti-Bob to Bob appears a ``sudden birth" with the increasing of Hawking temperature. We also find that the Gaussian steering is always asymmetric and the maximum steering asymmetry can \\emph{ exceed} $\\ln 2$ in curved spacetime, which is quite different from the flat spacetime case [Phys. Rev. Lett. 114, 060403 (2015)] where the steering asymmetry can \\emph{neve...

  18. Two Ways of Robust Quantum Dialogue by Using Four-Qubit Cluster State (United States)

    Wang, Rui-jin; Li, Dong-fen; Liu, Yao; Qin, Zhi-guang; Baagyere, Edward


    In this paper, we present a scheme for quantum dialogue by using a four-qubit cluster state as quantum channel.The scheme has two cases: Case 1, Sender Alice and receiver Bob share information using an orderly sequence of entangled state as quantum channel which was prepared by Alice. This case is achieved as follows: The two sides agreed to encode quantum state information, then Alice perform a bell state measurement for quantum information which has been encoded. This will convey the information to Bob, then Bob measuring his own qubits, through the analysis of the measurement results of Alice and Bob, Bob can obtain quantum information. For case 2, four-qubit cluster state and quantum state information is transmitted to form a total quantum system. In the Case 2 scenario, Alice and Bob perform bell state measurements for part of the qubits, and tell the measurement result to each other through the classical channel. Finally, according to the measurement result, Alice and Bob operate an appropriate unitary transformation, as a result, Alice's qubit will be renewed upon Bob's measurements, and also, Bob's qubit will be renewed upon Alice's measurements. Thus, a bidirectional quantum dialogue is achieved. After analysis, this scheme has high security by taking certain eavesdropping attacks into account. There is therefore a certain reference value to the realization of quantum dialogue.

    A scheme to teleport an unknown two-qubit state from Alice (the sender) to Bob (the receiver) using two Einstein-Podolsky-Rosen (EPR) pairs is presented, each EPR pair being shared by both Alice and Bob. Firstly, Alice combines each of the two particles in the teleported state with an EPR particle and makes Bell state measurement on each combination. Then she transmits the outcomes of her measurements to Bob classically. According to Alice′s measurement results, Bob can perform appropriate unitary operations on his two EPR particles to retrieve the initial state.

  12. An efficient two-step quantum key distribution protocol with orthogonal product states

    Institute of Scientific and Technical Information of China (English)

    Yang Yu-Guang; Wen Qiao-Yan; Zhu Fu-Chen


    An efficient two-step quantum key distribution (QKD) protocol with orthogonal product states in the n( )n(n ≥ 3) Hilbert space is presented. In this protocol, the particles in the orthogonal product states form two particle sequences.The sender, Alice, first sends one sequence to the receiver, Bob. After Bob receives the first particle sequence, Alice and Bob check eavesdropping by measuring a fraction of particles randomly chosen. After ensuring the security of the quantum channel, Alice sends the other particle sequence to Bob. By making an orthogonal measurement on the two particle sequences, Bob can obtain the information of the orthogonal product states sent by Alice. This protocol has many distinct features such as great capacity, high efficiency in that it uses all orthogonal product states in distributing the key except those chosen for checking eavesdroppers.

  13. A Doubly Exponentially Crumbled Cake

    CERN Document Server

    Christ, Tobias; Gebauer, Heidi; Matoušek, Jiří; Uno, Takeaki


    We consider the following cake cutting game: Alice chooses a set P of n points in the square (cake) [0,1]^2, where (0,0) is in P; Bob cuts out n axis-parallel rectangles with disjoint interiors, each of them having a point of P as the lower left corner; Alice keeps the rest. It has been conjectured that Bob can always secure at least half of the cake. This remains unsettled, and it is not even known whether Bob can get any positive fraction independent of n. We prove that if Alice can force Bob's share to tend to zero, then she must use very many points; namely, to prevent Bob from gaining more than 1/r of the cake, she needs at least 2^{2^{\\Omega(r)}} points.

    Thermal decomposition of LiPF6 and LiBC4O8 (lithium bis(oxalate)borate, abbreviated as LiBOB) were studied using TG (thermogravimetry)-DTG (derivative thermogravimetry) method with different heating rate of 5, 10, 20 and 40°C min-1 or at different constant temperature C (109.80, 118.79, 148.41, 176.86 °C for LiPF6 and 278.51, 298.13, 317.65, 336.13 for LiBOB). From the nonisothermal kinetics we calculate that LiPF6 is 1.01, LiBOB is 1.04, LiPF6 is 91907.61 J/mol, and LiBOB is 205179.88 J/mol; from the isothermal kinetics we calculate that n for both LiPF6 and LiBOB are 1, LiPF6 is 91907.61 J/mol, LiBOB is 205179.88 J/mol, lnALiPF6 is 16.89 s-1, and lnALiBOB is 31.96 s-1. The results obtained from the two ways have minor differences and can validate each other.

  15. Tri(ethylene glycol)-substituted trimethylsilane/lithium bis(oxalate)borate electrolyte for LiMn2O4/graphite system (United States)

    Kusachi, Yuki; Dong, Jian; Zhang, Zhengcheng; Amine, Khalil


    Silane-based electrolyte is a promising candidate for safer electrochemical energy storage devices because it is thermally and electrochemical stable, less flammable and environmental benign. In this paper, electrochemical properties of one of the silane-based electrolytes, tri(ethylene glycol)-substituted trimethylsilane (1NM3)-lithium bis(oxalate)borate (LiBOB) was studied using LiMn2O4 as cathode and MAG graphite as anode. When combined with LiBOB as lithium salt, the 1NM3-LiBOB electrolyte can provide solid electrolyte interface (SEI) formation due to the reductive decomposition of LiBOB at first charging cycle. Compared to the electrolyte used in the conventional lithium-ion batteries, 1NM3-LiBOB electrolyte showed compatible battery performance in LiMn2O4/MAG chemistry. The AC impedance measurement indicates that the activation energy (Ea) obtained from the charge transfer impedance for 1NM3-LiBOB was higher than that of the state-of-the-art electrolyte. Due to its low conductivity, the rate capability of 1NM3-LiBOB electrolyte needs to be improved.

  16. Dynamics of the Asian Summer Monsoon Onset and the Tibetan Plateau Impacts (United States)

    Yimin, Liu; Guoxiong, Wu; Boqi, Liu; Suling, Ren; Yue, Guan


    The formation and development of the South Asian High (SAH) in early spring over South China Sea (SCS) provides upper tropospheric pumping over the Southeast Bay of Bengal (BOB) and leads to the BOB monsoon onset. The strong latent heat release of the BOB monsoon results in the northeastward unstable development of the SAH which contributes to the SCS monsoon onset. The zonal asymmetric unstable development of the SAH after the SCS monsoon onset leads to the Indian summer monsoon onset. In spring over South BOB, usually there is vortex development preceding the Asian summer monsoon onset. The rapid development of the BOB monsoon onset vortex is due to the local strong air-sea interaction, which is modulated by the Tibetan Plateau (TP) forcing and the land-sea thermal contrast across South Asia. Strong heating from BOB monsoon generates stationary Rossby-wave in lower troposphere, producing weak cold advection and convection over North SCS. Development of surface BOB cyclone provides Northeastward water vapor transport towards North SCS where convection develops. Before the Indian Summer Monsoon (ISM) onset, the North- South land- sea thermal contrast increases eastward remarkably on the southeast of Arabian Sea. Air traveling eastward along the near- surface tropical westerly jet gets northward accelerated, forcing a lower tropospheric convergence near and to the north of the jet stream. Such a forced convection development occurs intensively over the southeastern Arabian Sea and southwestern India, contributing to the ISM onset.

  17. Influence of circulation parameters on the AOD variations over the Bay of Bengal during ICARB

    MODIS (Moderate Resolution Imaging Spectroradiometer) level-3 aerosol data, NCEP (National Centers for Environmental Prediction) reanalysis winds and QuikSCAT ocean surface winds were made use of to examine the role of atmospheric circulation in governing aerosol variations over the Bay of Bengal (BoB) during the first phase of the ICARB (Integrated Campaign for Aerosols, gases and Radiation Budget) campaign (March 18–April 12, 2006). An inter-comparison between MODIS level-3 aerosol optical depth (AOD) data and ship-borne MICROTOPS measurements showed good agreement with correlation 0.92 ( > 0.0001) and a mean MODIS underestimation by 0.01. During the study period, the AOD over BoB showed high values in the northern/north western regions, which reduced towards the central and southern BoB. The wind patterns in lower atmospheric layers (< 850 hPa) indicated that direct transport of aerosols from central India was inhibited by the presence of a high pressure and a divergence over BoB in the lower altitudes. On the other hand, in the upper atmospheric levels, winds from central and northern India stretched south eastwards and converged over BoB with a negative vorticity indicative of a downdraft. These wind patterns pointed to the possibility of aerosol transport from central India to BoB by upper level winds. This mechanism was further confirmed by the significant correlations that AOD variations over BoB showed with aerosol flux convergence and flux vorticity at upper atmospheric levels (600–500 hPa). AOD in central and southern BoB away from continental influences displayed an exponential dependence on the QuikSCAT measured ocean surface wind speed. This study shows that particles transported from central and northern India by upper atmospheric circulations as well as the marine aerosols generated by ocean surface winds contributed to the AOD over the BoB during the first phase of ICARB.

  18. Upconversion-based receivers for quantum hacking-resistant quantum key distribution (United States)

    Jain, Nitin; Kanter, Gregory S.


    We propose a novel upconversion (sum frequency generation)-based quantum-optical system design that can be employed as a receiver (Bob) in practical quantum key distribution systems. The pump governing the upconversion process is produced and utilized inside the physical receiver, making its access or control unrealistic for an external adversary (Eve). This pump facilitates several properties which permit Bob to define and control the modes that can participate in the quantum measurement. Furthermore, by manipulating and monitoring the characteristics of the pump pulses, Bob can detect a wide range of quantum hacking attacks launched by Eve.

  19. Radiative properties of Bay of Bengal aerosols: Spatial distinctiveness and source impacts (United States)

    Babu, S. Suresh; Gogoi, Mukunda M.; Kumar, V. H. Arun; Nair, Vijayakumar S.; Moorthy, K. Krishna


    Simultaneous and collocated measurements of spectrally resolved scattering and absorption coefficients and mass concentration of near-surface composite aerosols in the marine atmosphere over the Bay of Bengal (BOB), along with incoming shortwave (0.3-3 μm) global solar radiation and columnar spectral aerosol optical depths (AOD), were made on a research cruise during the winter phase of the Integrated Campaign for Aerosols, Gases and Radiation Budget (W-ICARB). The aerosol radiative properties revealed distinct spatial features associated with the contrasting outflows from Indo-Gangetic Plain (IGP) and East Asia. Both scattering and absorption coefficients depicted very high values (>200 and >15 Mm-1) over the northwestern and southeastern BOB and extremely low values (<50 and <10 Mm-1) over the central BOB. The mean value of the total scattering coefficient at 550 nm (˜123.7 ± 85.3 Mm-1) over the entire BOB during winter was higher than the mean values (˜94 ± 47 Mm-1) reported for the premonsoon season. While SSA at 550 nm showed very low values (<0.8) over a very large region in the central BOB and moderately low values over the southern BOB (˜0.85-0.9), the columnar AOD varied from the least values of ˜0.1 over the northeastern BOB to the highest values of ˜0.8 over the northwestern BOB. While significant cooling was observed at the top of the atmosphere and surface over the northwestern BOB, the atmospheric forcing was found to be significantly high (˜15 W m-2) over the southern BOB, where the aerosol radiative forcing efficiency (ARFE) at the surface was also found to be high. Examination of the Moderate Resolution Imaging Spectroradiometer (MODIS)-derived fire count along with the advection pathways revealed a strong contribution from the emissions of biomass smoke from East Asia, which might be contributing to the enhanced aerosol induced warming over the southern BOB. However, the ARFE at the surface was low over the northwestern BOB, where the

  12. Blind Quantum Computation

    CERN Document Server

    Arrighi, P; Arrighi, Pablo; Salvail, Louis


    We investigate the possibility of having someone carry out the work of executing a function for you, but without letting him learn anything about your input. Say Alice wants Bob to compute some well-known function f upon her input x, but wants to prevent Bob from learning anything about x. The situation arises for instance if client Alice has limited computational resources in comparison with mistrusted server Bob, or if x is an inherently mobile piece of data. Could there be a protocol whereby Bob is forced to compute f(x) "blindly", i.e. without observing x? We provide such a blind computation protocol for the class of functions which admit an efficient procedure to generate random input-output pairs, e.g. factorization. The setting is quantum, the security is unconditional, the eavesdropper is as malicious as can be. Keywords: Secure Circuit Evaluation, Secure Two-party Computation, Information Hiding, Information gain vs disturbance.

  17. Uncertainty relations and approximate quantum error correction (United States)

    Renes, Joseph M.


    The uncertainty principle can be understood as constraining the probability of winning a game in which Alice measures one of two conjugate observables, such as position or momentum, on a system provided by Bob, and he is to guess the outcome. Two variants are possible: either Alice tells Bob which observable she measured, or he has to furnish guesses for both cases. Here I derive uncertainty relations for both, formulated directly in terms of Bob's guessing probabilities. For the former these relate to the entanglement that can be recovered by action on Bob's system alone. This gives an explicit quantum circuit for approximate quantum error correction using the guessing measurements for "amplitude" and "phase" information, implicitly used in the recent construction of efficient quantum polar codes. I also find a relation on the guessing probabilities for the latter game, which has application to wave-particle duality relations.

  19. Oscillating pendulum decay by emission of vortex rings (United States)

    Bolster, Diogo; Hershberger, Robert E.; Donnelly, Russell J.


    We have studied oscillation of a pendulum in water using spherical bobs. By measuring the loss in potential energy, we estimate the drag coefficient on the sphere and compare to data from liquid-helium experiments. The drag coefficients compare very favorably illustrating the true scaling behavior of this phenomenon. We also studied the decay of amplitude of the pendulum over time. As observed previously, at small amplitudes, the drag on the bob is given by the linear Stokes drag and the decay is exponential. For larger amplitudes, the pendulum bob sheds vortex rings as it reverses direction. The momentum imparted to these vortex rings results in an additional discrete drag on the bob. We present experiments and a theoretical estimate of this vortex-ring-induced drag. We analytically derive an estimate for a critical amplitude beyond which vortex ring shedding will occur as well as an estimate of the radius of the ring as a function of amplitude.

  1. Location-Oblivious Data Transfer with Flying Entangled Qudits

    CERN Document Server



    We present a simple and practical quantum protocol involving two mistrustful agencies in Minkowski space, which allows Alice to transfer data to Bob at a spacetime location that neither can predict in advance. The location depends on both Alice's and Bob's actions. The protocol guarantees unconditionally to Alice that Bob learns the data at a randomly determined location; it guarantees to Bob that Alice will not learn the transfer location even after the protocol is complete. The task implemented, transferring data at a space-time location that remains hidden from the transferrer, has no precise analogue in non-relativistic quantum cryptography. It illustrates further the scope for novel cryptographic applications of relativistic quantum theory.

    Institute of Scientific and Technical Information of China (English)

    YAN Feng-Li; GAO Ting; LI You-Cheng


    @@ We propose a scheme of quantum secret sharing between Alice's group and Bob's group with single photons and unitary transformations. In the protocol, one member in Alice's group prepares a sequence of single photons in one of four different states, while other members directly encode their information on the sequence of single photons via unitary operations; after that, the last member sends the sequence of single photons to Bob's group.Then Bob's, except for the last one, do work similarly. Finally the last member in Bob's group measures the qubits. If the security of the quantum channel is guaranteed by some tests, then the qubit states sent by the last member of Alice's group can be used as key bits for secret sharing. It is shown that this scheme is safe.

After Alice has published the matching information of the particle sequence, Bob recovers the correct correspondences and makes an orthogonal measurement on the orthogonal product states to obtain the information sent by Alice. Finally, security analysis is also made.

  18. Permanently Secure Quantum Bit Commitment from a Temporary Computation Bound

    CERN Document Server

    Kent, A


    Alice is a private citizen whose computational resources are modest. Bob represents a large organisation at the forefront of computational and cryptological research. Bob's computational and cryptanalytic power is unknown to Alice, but Bob can confidently estimate a bound on Alice's ability to carry out a computation that would break a classical bit commitment. Alice wishes to commit a bit to Bob. She requires that he will never be able to decode it unless she chooses to reveal it, but also that if she does he will be confident that her commitment was genuine. We describe here a simple quantum bit commitment scheme which satisfies these criteria. By iterating the scheme, we obtain quantum bit commitment schemes which allow either Alice or Bob to commit bits to the other. These schemes do not contradict Mayers' and Lo and Chau's no-go results: they rely on a temporary computability bound. However, they are permanently secure against cheating by either party, provided only that Alice was not able to break Bob's...

  19. Gaussian quantum steering and its asymmetry in curved spacetime (United States)

    Wang, Jieci; Cao, Haixin; Jing, Jiliang; Fan, Heng


    We study Gaussian quantum steering and its asymmetry in the background of a Schwarzschild black hole. We present a Gaussian channel description of quantum state evolution under the influence of Hawking radiation. We find that thermal noise introduced by the Hawking effect will destroy the steerability between an inertial observer Alice and an accelerated observer Bob who hovers outside the event horizon, while it generates steerability between Bob and a hypothetical observer anti-Bob inside the event horizon. Unlike entanglement behaviors in curved spacetime, here the steering from Alice to Bob suffers from a "sudden death" and the steering from anti-Bob to Bob experiences a "sudden birth" with increasing Hawking temperature. We also find that the Gaussian steering is always asymmetric and the maximum steering asymmetry cannot exceed ln 2 , which means the state never evolves to an extremal asymmetry state. Furthermore, we obtain the parameter settings that maximize steering asymmetry and find that (i) s =arccosh cosh/2r 1 -sinh2r is the critical point of steering asymmetry and (ii) the attainment of maximal steering asymmetry indicates the transition between one-way steerability and both-way steerability for the two-mode Gaussian state under the influence of Hawking radiation.

    Objective:To investigate the leishmanicidal effect of the Bixa orellana crude seed extract and its fractions against Leishmania amazonensis. Methods:Four main fractions (BO-A, BO-B, BO-C and BO-D) were obtained by exhaustion with solvent with increased polarity from the Bixa orellana crude seed extract and 28 sub-fractions. The antileishmanial activity was evaluated in intracellular amastigotes and the cytotoxicity was assessed in murine intraperitoneal macrophages. Results:The BO-A and BO-B fractions showed a good antileishmanial activity with IC50 values of (12.9±4.1) and (12.4±0.3) μg/mL, respectively. The sub-fractions BO-B1 (IC50=(11.8±3.8) μg/mL) and BO-B3 [IC50=(13.6±4.7) μg/mL] also proved to have a good leishmanicidal effect. In general, the sub-fractions showed a lower toxicity than the crude extract. A selectivity index of 9 indicated a moderate selectivity of the BO-A, BO-B and BO-C fractions and BO-B1 sub-fraction. Conclusions: Potential of this plant against cutaneous leishmaniasis should be further investigated.

  1. Prey processing in the Siamese fighting fish (Betta splendens). (United States)

    Konow, Nicolai; Krijestorac, Belma; Sanford, Christopher P J; Boistel, Renauld; Herrel, Anthony


    We studied prey processing in the Siamese fighting fish (Betta splendens), involving slow, easily observed head-bobbing movements, which were compared with prey processing in other aquatic feeding vertebrates. We hypothesized that head-bobbing is a unique prey-processing behaviour, which alternatively could be structurally and functionally analogous with raking in basal teleosts, or with pharyngognathy in neoteleosts. Modulation of head-bobbing was elicited by prey with different motility and toughness. Head-bobbing involved sustained mouth occlusion and pronounced cranial elevation, similar to raking. However, the hyoid and pectoral girdle were protracted, and not retracted as in both raking and pharyngognathy. High-speed videofluoroscopy of hyoid movements confirmed that head-bobbing differs from other known aquatic prey-processing behaviours. Nevertheless, head-bobbing and other prey-processing behaviours converge on a recurrent functional theme in the trophic ecology of aquatic feeding vertebrates; the use of intraoral and oropharyngeal dentition surfaces to immobilize, reduce and process relatively large, tough or motile prey. Prey processing outside the pharyngeal region has not been described for neoteleosts previously, but morphological evidence suggests that relatives of Betta might use similar processing behaviours. Thus, our results suggest that pharyngognathy did not out-compete ancestral prey-processing mechanisms completely during the evolution of neoteleosts.

  3. Effect of the early and late onset of summer monsoon over the Bay of Bengal on Asian precipitation in May (United States)

    Xing, Nan; Li, Jianping; Wang, Lanning


    The impact of early and late Bay of Bengal (BoB) summer monsoon (BoBSM) onset on Asian precipitation in May is investigated. When the BoBSM occurs earlier (later), May rainfall tends to be enhanced (suppressed) in the southern Indian peninsula (SIP), the Indochinese peninsula (ICP), southwest China (SWC) and the South China Sea (SCS), while south China (SC) rainfall tends to be suppressed (enhanced). When the BoBSM occurs earlier than the climatological mean (late April), strong convective activity emerges earlier over the BoB, which causes local strong convective heating earlier. Then, earlier spread of heating in the BoB towards both sides leads to earlier retreat of the subtropical highs in the western Pacific (WPSH) and Indian Ocean outwards the BoB. Thus, compared to the climatological mean, the two subtropical highs present larger retreat outwards the BoB and smaller meridional extent over the SCS and Arabian Sea in May, which contributes to positive heating anomalies over the SCS and Arabian Sea. Therefore, anomalous cyclonic circulations occur over the BoB, SCS and Arabian Sea in May. Anomalous cyclonic circulation is favorable for low-level convergence over the SIP, and thus resulting in local heavy rainfall. Associated with cyclonic circulation anomalies over the BoB and SCS, anomalous low-level convergent winds and ascending flows favor positive precipitation anomalies in the ICP, SWC, and SCS, while anomalous northeasterlies and descending flows affected by the southward retreat of the WPSH lessen SC rainfall. In late onset years the opposite occurs.

  4. Air Pollution over North-West Bay of Bengal in the Early Post-Monsoon Season Based on NASA MERRAero Data (United States)

    Kishcha, Pavel; DaSilva, Arlindo M.; Starobinets, Boris; Alpert, Pinhas


    The MERRA Aerosol Reanalysis (MERRAero) has been recently developed at NASA's Global Modeling Assimilation Office (GMAO). This reanalysis is based on a version of the GEOS-5 model radiatively coupled with GOCART aerosols, and it includes assimilation of bias-corrected Aerosol Optical Thickness (AOT) from the MODIS sensor on both Terra and Aqua satellites. Our main finding is that, in October, in the absence of aerosol sources in north-west Bay of Bengal (BoB), MERRAero showed increasing AOT trends over north-west BoB exceeding those over the east of the Ganges basin. The Ganges basin is characterized by significant population growth accompanied by developing industry, agriculture, and increasing transportation: this has resulted in declining air quality. MERRAero data for the period 2002-2009 was used to study AOT trends over north-west Bay of Bengal (BoB) in the early post-monsoon season. This season is characterized by aerosol transport from the Ganges basin to north-west BoB by prevailing winds; and still significant rainfall of over 150 mmmonth. Different aerosol components showed strong increasing AOT trends over north-west BoB. The following factors contributed to the increasing AOT trend over the area in question in October: an increasing number of days when prevailing winds blew from land to sea, resulting in a drier environment and an increase in air pollution over north-west BoB; wind convergence was observed over north-west BoB causing the accumulation of aerosol particles over that region, when prevailing winds blew from land to sea. MERRAero aerosol reanalysis can be used on a global scale.

  5. Obituary: Robert C. Bless (1927 - 2015) (United States)

    Surrounded by his loving family, Robert Charles Bless died at home on November 29th, three days before his 88th birthday. He was born in Ithaca, NY on Dec. 3, 1927 to a Russian father, Arthur Aaron Bless, and a French mother, Eva Chantrell Bless. Bob spent many summers on the family farm in the South of France, where he gained a great pride and joy in his French heritage, large extended family, and mother tongue. As a child growing up in Gainesville, FL, Bob's first job was snake wrangling, earning 10 cents per foot, with an added bonus for the more venomous species. Young Robbie took daily adventures in the Florida woods and swamps, armed only with pockets full of pecans and oranges. He enjoyed spending time at the family's lake cabin, where he learned to sail and helped his father plant acres of trees to grow their timber plantation. As a first generation immigrant, Bob's father received a PhD in physics, which inspired Bob to pursue an extensive educational route in astrophysics. Bob excelled in academics, graduating high school at the age of 16 and the University of Florida (B.Sc.) at 19. His path to graduate school was interrupted by a diagnosis of tuberculosis that forced him into a Florida sanitorium for one year. During this time, Bob made the most of what he described as the most dismal part of life by advocating for patient rights, initiating an inter-sanitorium newsletter, and gaining skills and experience in community organization and leadership - qualities that would later inform his leadership in academe. After being one of the first successfully treated tuberculosis patients in the US, Bob went on to earn a M.Sc. from Cornell University, and received his PhD degree in Astronomy from the University of Michigan in 1958. That same year, Bob joined the staff of the Astronomy Department of the University of Wisconsin (UW), Madison. It was there that Bob met Diane McQueen. Despite Bob's Dodge Dart and what has been described as the worst first date in

  6. Secure communication via quantum illumination (United States)

    Shapiro, Jeffrey H.; Zhang, Zheshen; Wong, Franco N. C.


    In the quantum illumination protocol for secure communication, Alice prepares entangled signal and idler beams via spontaneous parametric downconversion. She sends the signal beam to Bob, while retaining the idler. Bob imposes message modulation on the beam he receives from Alice, amplifies it, and sends it back to her. Alice then decodes Bob's information by making a joint quantum measurement on the light she has retained and the light she has received from him. The basic performance analysis for this protocol—which demonstrates its immunity to passive eavesdropping, in which Eve can only listen to Alice and Bob's transmissions—is reviewed, along with the results of its first proof-of-principle experiment. Further analysis is then presented, showing that secure data rates in excess of 1 Gbps may be possible over 20-km-long fiber links with technology that is available or under development. Finally, an initial scheme for thwarting active eavesdropping, in which Eve injects her own light into Bob's terminal, is proposed and analyzed.

  7. Influence of Summer Monsoon on Asymmetric Bimodal Pattern of Tropical Cyclogenesis Frequency over the Bay of Bengal

    Institute of Scientific and Technical Information of China (English)

    XING Wen; HUANG Fei


    influence of summer monsoon on tropical cyclone (TC) genesis over the Bay of Bengal (BoB) is explored using an empirical genesis potential (GP) index.The annual cycle of cyclogenesis frequency over the BoB shows an asymmetric bimodal pattern with the maximum genesis number appearing in late October and the second largest in early May.The two peaks correspond to the withdrawal and onset of the BoB summer monsoon,respectively.The semimonthly GP index calculated without TC days over the BoB is consistent with TC genesis frequency,indicating that the index captures the monsoon-induced changes in the environment that are responsible for the seasonal variation of TC genesis frequency.Of the four environmental variables (i.e.,low-level vorticity,mid-level relative humidity,potential intensity,and vertical wind shear) that enter into the GP index,the potential intensity makes the largest contribution to the bimodal distribution,followed by vertical wind shear due to small wind speed during the summer monsoon onset and withdrawal.The difference in TC genesis frequency between autumn and late spring is mainly owing to the relative humidity difference because a divergence (convergence) of horizontal moisture flux associated with cold dry northerlies (warm wet westerlies) dominates the BoB in late spring (autumn).

  8. Spatial and temporal variability of chlorophyll in Bay of Bengal. (United States)

    Jutla, A.; Akanda, S.; Islam, S.


    The Bay of Bengal (BoB) receives approximately 628 km3/ year of freshwater discharge from the Ganges and Brahmaputra rivers. Freshwater discharge from rivers increases the nutrient load and thereby enhances phytoplankton production in the BoB. Cholera, an infectious water-borne disease caused by bacterium Vibrio cholerae, remains endemic in the BoB region. Phytoplankton provides favorable environment for survival of cholera bacteria. Therefore, for development of any predictive model for cholera, it is important to quantify the spatial and temporal variability of phytoplankton in the BoB. Satellite remote sensing is the most effective way to quantify this variability over a range of space and time scales. Using ten years (1998-2007) of daily, weekly and monthly SeaWiFs chlorophyll, a surrogate variable for measuring phytoplankton, imagery we explore the spatial pattern and dominant temporal variability of chlorophyll over the BoB region. We find that chlorophyll in the coastal waters has more variability, both in temporal and spatial scales, than the offshore waters. Mechanism of production and space-time variability of coastal chlorophyll is different from those of offshore chlorophyll. While coastal chlorophyll is dominated by influx of terrestrial nutrients through river discharge, chlorophyll in the offshore region is primarily controlled by oceanic processes. We will also explore issues related to dominant space and time scales of chlorophyll variations in the entire bay.

    Concentrations of ambient NH{sub 3}, NO, NO{sub 2} and SO{sub 2} were measured over Bay of Bengal (BoB) during 28 December 2008 to 25 January 2009 to study their diurnal variation and relationship of NH{sub 3} with other trace gases over BoB. The measurements were done under the winter phase of Integrated Campaign on Aerosols and Radiation Budget (WICARB). For the first time, ambient NH{sub 3} was monitored precisely over BoB based on chemiluminescence method, having estimation efficiency more precise than the chemical trap method. The average concentration of ambient NH{sub 3}, NO, NO{sub 2} and SO{sub 2} were recorded as 4.78{+-}1.68, 1.89{+-}1.26, 0.31{+-}0.14 and 0.80{+-}0.30 {mu}gm{sup -3}, respectively, over BoB. The prominent latitudinal and longitudinal variations of the trace gases were observed over BoB, whereas NH{sub 3} and NO showed the non-significant diurnal variation. Results reveal that the concentration of ambient NH{sub 3} negatively correlated with ambient NO{sub 2} (r{sup 2} =.0.56), SO{sub 2} (r{sup 2} =.0.58) and ambient temperature (r{sup 2} =.0.27) during the study.

  10. Controlled quantum teleportation and secure direct communication

    Institute of Scientific and Technical Information of China (English)

    Gao Ting; Yan Feng-Li; Wang Zhi-Xi


    We present a controlled quantum teleportation protocol. In the protocol, quantum information of an unknown state of a 2-level particle is faithfully transmitted from a sender Alice to a remote receiver Bob via an initially shared triplet of entangled particles under the control of the supervisor Charlie. The distributed entangled particles shared by Alice, Bob and Charlie function as a quantum information channel for faithful transmission. We also propose a controlled and secure direct communication scheme by means of this teleportation. After ensuring the security of the quantum channel, Alice encodes the secret message directly on a sequence of particle states and transmits them to Bob supervised by Charlie using this controlled quantum teleportation. Bob can read out the encoded message directly by the measurement on his qubit. In this scheme, the controlled quantum teleportation transmits Alice's message without revealing any information to a potential eavesdropper. Because there is not a transmission of the qubit carrying the secret message between Alice and Bob in the public channel, it is completely secure for controlled and direct secret communication if perfect quantum channel is used. The special feature of this scheme is that the communication between two sides depends on the agreement of a third side to co-operate.

  11. Controlled quantum secure direct communication by entanglement distillation or generalized measurement (United States)

    Tan, Xiaoqing; Zhang, Xiaoqian


    We propose two controlled quantum secure communication schemes by entanglement distillation or generalized measurement. The sender Alice, the receiver Bob and the controllers David and Cliff take part in the whole schemes. The supervisors David and Cliff can control the information transmitted from Alice to Bob by adjusting the local measurement angles θ _4 and θ _3. Bob can verify his secret information by classical one-way function after communication. The average amount of information is analyzed and compared for these two methods by MATLAB. The generalized measurement is a better scheme. Our schemes are secure against some well-known attacks because classical encryption and decoy states are used to ensure the security of the classical channel and the quantum channel.

  12. Asymmetric quantum dialogue in noisy environment (United States)

    Banerjee, Anindita; Shukla, Chitra; Thapliyal, Kishore; Pathak, Anirban; Panigrahi, Prasanta K.


    A notion of asymmetric quantum dialogue (AQD) is introduced. Conventional protocols of quantum dialogue are essentially symmetric as the users (Alice and Bob) can encode the same amount of classical information. In contrast, the proposed scheme for AQD provides different amount of communication powers to Alice and Bob. The proposed scheme offers an architecture, where the entangled state to be used and the encoding scheme to be shared between Alice and Bob depend on the amount of classical information they want to exchange with each other. The general structure for the AQD scheme has been obtained using a group theoretic structure of the operators introduced in Shukla et al. (Phys Lett A 377:518, 2013). The effect of different types of noises (e.g., amplitude damping and phase damping noise) on the proposed scheme is investigated, and it is shown that the proposed scheme for AQD is robust and it uses an optimized amount of quantum resources.

  13. Physical Layer Security with Uncoordinated Helpers Implementing Cooperative Jamming

    CERN Document Server

    Luo, Shuangyu; Petropulu, Athina


    A wireless communication network is considered, consisting of a source (Alice), a destination (Bob) and an eavesdropper (Eve), each equipped with a single antenna. The communication is assisted by multiple helpers, each equipped with two antennas, which implement cooperative jamming, i.e., transmitting noise to confound Eve. The optimal structure of the jamming noise that maximizes the secrecy rate is derived. A nulling noise scenario is also considered, in which each helper transmits noise that nulls out at Bob. Each helper only requires knowledge of its own link to Bob to determine the noise locally. For the optimally structured noise, global information of all the links is required. Although analysis shows that under the two-antenna per helper scenario the nulling solution is sub-optimal in terms of the achievable secrecy rate, simulations show that the performance difference is rather small, with the inexpensive and easy to implement nulling scheme performing near optimal.

  14. Hiding Quantum Information in the Perfect Code

    CERN Document Server

    Shaw, Bilal A


    We present and analyze a protocol for quantum steganography where the sender (Alice) encodes her steganographic information into the error syndromes of the perfect (five-qubit) quantum error-correcting code, and sends it to the receiver (Bob) over a depolarizing channel. Alice and Bob share a classical secret key, and hide quantum information in such a way that to an eavesdropper (Eve) without access to the secret key, the quantum message looks like an innocent codeword with a typical sequence of quantum errors. We calculate the average rate of key consumption, and show how the protocol improves in performance as information is spread over multiple codeword blocks. Alice and Bob utilize different encodings to optimize the average number of steganographic bits that they can send to each other while matching the error statistics of the depolarizing channel.

  15. Entanglement creation and distribution on a graph of exchange-coupled qutrits

    CERN Document Server

    Hadley, C; Bose, S; Hadley, Christopher; Serafini, Alessio; Bose, Sougato


    We propose a protocol that allows both the creation and distribution of entanglement, resulting in two distant parties (Alice and Bob) conclusively sharing a bipartite Bell State. The system considered is as graph of three-level objects ("qutrits") coupled by SU(3) exchange operators. The protocol begins with a third party (Charlie) encoding two lattice sites in unentangled states, and allowing unitary evolution under time. Alice and Bob perform a projective measurement on their respective qutrits at a given time, and obtain a maximally-entangled Bell state with a certain probablility. We also consider two protocols, one based on simple repetition and the other based on successive measurements and conditional resetting, and show that the cumulative probability of creating a Bell state between Alice and Bob tends to unity.

  16. Secure Capacity Region for Erasure Broadcast Channels with Feedback

    Czap, László; Diggavi, Suhas; Fragouli, Christina


    We formulate and study a cryptographic problem relevant to wireless: a sender, Alice, wants to transmit private messages to two receivers, Bob and Calvin, using unreliable wireless broadcast transmissions and short public feedback from Bob and Calvin. We ask, at what rates can we broadcast the private messages if we also provide (information-theoretic) unconditional security guarantees that Bob and Calvin do not learn each-other's message? We characterize the largest transmission rates to the two receivers, for any protocol that provides unconditional security guarantees. We design a protocol that operates at any rate-pair within the above region, uses very simple interactions and operations, and is robust to misbehaving users.

  17. Probabilistic Teleportation of an Unknown One-Particle State by a Three-Particle General W State

    Institute of Scientific and Technical Information of China (English)

    XIU Xiao-Ming; DONG Li; GAO Ya-Jun


    Two schemes for teleporting an unknown one-particle state are proposed when a general W state is utilized as quantum channel.In the first scheme,after the sender (Alice) makes a Bell-state measurement on her particles,the recipient (Bob) performs a Von Neumann measurement and introduces an auxiliary particle,and carries out a unitary transformation on his particle and the auxiliary particle,and performs a Von Neumann measurement on the auxiliary particle to confirm whether the teleportation succeeds or not.In the second scheme,the recipient (Bob) does not need to perform the first Von Neumann measurement or introduce the auxiliary particle,which is necessary in the first scheme.It is shown that the maximal probabilities of successful teleportation of the two schemes are identical if the recipient (Bob) performs an appropriate unitary transformation and adopts a proper particle on which he recovers the quantum information of state to be teleported.

    Sheath, Karen L; Duffy, Lisa; Asquith, Philip; Love, Donald R; George, Alice M


    The aim of the present study was to evaluate the use of KaryoLite™ bacterial artificial chromosomes (BACs)‑on‑Beads™ (BoBs) technology for the rapid screening of products of conception (POC). Validation and prospective studies were carried out on 85 and 95 patient samples, respectively. Validation studies had previously been analyzed using routine culture and G-banded karyotyping. BoBs resulted in an abnormality detection frequency of 27%, with a failure rate of <3%. The time required for processing was significantly lower compared with that of tissue culture. In conclusion, BoBs technology decreased the failure rate, while increasing the analytical sensitivity compared with G-banded karyotype analysis alone. Additionally, significant cost savings may be achieved with regard to the time of processing and analysis of specimens.

  1. One Is a Claim, Two Is a Defense: Bringing an End to the Equal Opportunity Harasser Defense

    Directory of Open Access Journals (Sweden)

    Mark J. McCullough


    Full Text Available Consider the following three workplace scenarios. Alice, a female employee at ABC corporation, has been subjected to almost continuous harassment by her immediate supervisor, Bob, for the past two months. Several times each week, Bob makes crude and sexually suggestive comments and, on numerous occasions, Bob has touched Alice inappropriately in the workplace. Assuming Alice attempts to remedy this situation in a reasonable time period and her employer has unreasonably failed “to prevent and correct promptly any sexually harassing behavior,” Alice will most likely be able to bring a hostile workplace sex discrimination claim against her employer for Bob’s sexual harassment under Title VII of the Civil Rights Act of 1964.3

  2. Interactive simulations for quantum key distribution

    CERN Document Server

    Kohnle, Antje


    Secure communication protocols are becoming increasingly important, e.g. for internet-based communication. Quantum key distribution allows two parties, commonly called Alice and Bob, to generate a secret sequence of 0s and 1s called a key that is only known to themselves. Classically, Alice and Bob could never be certain that their communication was not compromised by a malicious eavesdropper. Quantum mechanics however makes secure communication possible. The fundamental principle of quantum mechanics that taking a measurement perturbs the system (unless the measurement is compatible with the quantum state) also applies to an eavesdropper. Using appropriate protocols to create the key, Alice and Bob can detect the presence of an eavesdropper by errors in their measurements. As part of the QuVis Quantum Mechanics Visualization Project, we have developed a suite of four interactive simulations that demonstrate the basic principles of three different quantum key distribution protocols. The simulations use either...

  3. Securing Communication via Transmission of Artificial Noise by Both Sides: Bipolar-Beamforming Optimization

    Directory of Open Access Journals (Sweden)

    Yongkai Zhou


    Full Text Available The paper considers the secure transmission in a wireless environment in which both the transmitter (Alice and the legitimate receiver (Bob send artificial noise (AN to interfere with the eavesdropper (Eve. Optimal design is analyzed in detail for this AN-by-both-side model to deal with Eve’s stochastic channel condition and random spatial distribution. Bipolar-beamforming is first proposed to jointly design Alice and Bob’s transmitting signals. By optimally assigning the transmitting antenna for Bob and allocating the power ratio between Alice’s information and the AN signal, maximum secrecy capacity can be achieved. Simulation is done to illustrate the process of bipolar-beamforming optimization. Results show that the AN-by-both-side model has good secrecy performance on both average and extreme conditions as Eve approaches Alice or Bob.

    Institute of Scientific and Technical Information of China (English)

    Yang Jie


    Utilizing both the general quantum teleportation and the two-step protocol, a new method is presented by which multi-qubit quantum information can be teleported in a much easier way from a sender Alice to a receiver Bob via the control of many agents in a network than by Yang et al's method. In this method, only all the agents collaborate with Bob can the unknown states in Alice's qubits be fully reconstructed in Bob's qubits. Comparisons between the method and Yang et al's method are made. Results show that, in this method, the preparation difficulty of initial states and the identification difficulty of entangled states are considerably reduced, new method is more feasible in technique, and Hadamard operations are not needed at all.

  6. Common knowledge: Now you have it, now you don`t?

    Energy Technology Data Exchange (ETDEWEB)

    Fagin, R.; Halpern, J.Y. [IBM Almaden Research Center, San Jose, CA (United States); Moses, Y. [Weizmann Institute of Science, Rehovot (Israel); Vardi, M.Y. [Rice Univ., Houston, TX (United States)


    The notion of common knowledge, where everyone knows, everyone knows that everyone knows, etc., has proven to be fundamental in various disciplines, including Philosophy, Artificial Intelligence, Economics, and Psychology. This key notion was first studied by the philosopher David Lewis in the context of conventions. Lewis pointed out that in order for something to be a convention, it must in fact be common knowledge among the members of a group. (For example, the convention that green means {open_quotes}go{close_quotes} and red means {open_quotes}stop{close_quotes} is presumably common knowledge among the drivers in our society.) Common knowledge also arises in discourse understanding. Suppose Ann asks Bob {open_quotes}What did you think of the movie?{close_quotes} referring to a showing of Monkey Business they have just seen. Not only must Ann and Bob both know that {open_quotes}the movie{close_quotes} refers to Monkey Business, but Ann must know that Bob knows, Bob must know that Ann knows that Bob knows, and so on. In fact, by a closer analysis of this situation, it can be shown that there must be common knowledge of what movie is meant in order for Bob to answer the question appropriately. Finally, common knowledge also turns out to be a prerequisite for agreement and coordinated action in distributed systems. This is precisely what makes it such a crucial notion in the analysis of interacting groups of agents. On the other hand, in practical settings common knowledge is impossible to achieve. This puts us in a somewhat paradoxical situation, in that we claim both that common knowledge is a prerequisite for agreement and coordinated action and that it cannot be attained. We discuss two answers to this paradox: Modeling the world with a coarser granularity, and relaxing the requirements for coordination.

  7. Interannual variation of tropical cyclone energy metrics over North Indian Ocean (United States)

    Mohapatra, M.; Vijay Kumar, V.


    There is decreasing trend in the tropical cyclone (TC) number over the North Indian Ocean (NIO) in recent years, though there is increasing trend in the sea surface temperature (SST) which is one of the main environmental parameters for the development and intensification of TCs. Hence, a study has been performed to understand whether any trend exists in other TC parameters such as velocity flux (VF), accumulated cyclone energy (ACE) and power dissipation index (PDI). The interseasonal and interannual variations of VF, ACE and PDI for the NIO as a whole and Bay of Bengal (BOB) and Arabian Sea (AS) are analysed based on the data of 1990-2013 (24 years). Role of large scale features like El Nino southern oscillation (ENSO) and Indian Ocean dipole (IOD) have also been analyzed. The mean ACE per year for TCs [maximum sustained wind of 34 knots (kt) or more] over the NIO is about 13.1 × 104 kt2 including 9.5 × 104 kt2 over the BOB and 3.6 × 104 kt2 over the AS. The mean PDI per year for TCs over the NIO is about 10 × 106 kt3 including 3 × 106 kt3 over the AS and 7 × 106 kt3 over the BOB. The VF, ACE and PDI of TCs are significantly less over BOB during post-monsoon season (Oct.-Dec.) of El Nino years than in La Nina and normal years. The VF for TCs over the BOB during post-monsoon season is significantly less (higher) during positive (negative) IOD years. There is significant decreasing trend at 95 % level of confidence in ACE and PDI of TCs over AS during post-monsoon season and PDI over the BOB and NIO during pre-monsoon season mainly due to similar trend in average intensity of TCs and not due to trends in SST over Nino regions or IOD index.

  9. Black carbon and carbon monoxide over Bay of Bengal during W_ICARB: Source characteristics (United States)

    Girach, I. A.; Nair, Vijayakumar S.; Babu, S. Suresh; Nair, Prabha R.


    The ship borne measurements of near-surface black carbon (BC) and carbon monoxide (CO) were carried out over Bay of Bengal (BoB) during the winter period of 2009 under W_ICARB, the second phase of ‘Integrated Campaign for Aerosols, gases and Radiation Budget (ICARB)'. The CO mixing ratio and BC mass concentration varied in the ranges of 80-480 ppbv and 75-10,000 ng m-3, respectively over this marine region. The BC and CO showed similar variations over northern BoB where airmass from Indo-Gangetic Plain (IGP) region prevailed during the observations period leading to a very strong positive correlation. The association of BC and CO was poor over the eastern and southern part of BoB could be due to the removal of BC aerosols by rain and/or processes of dilution and mixing while transported over to BoB. The highest value of CO observed over eastern BoB was partially due to biomass burning over East Asia. The BC/CO ratio for IGP airmass found to be 20.3 ng m-3 ppb-1 and ∼16 ng m-3 ppb-1 during winter and pre-monsoon, respectively which indicate the role of biomass burning as the source of BC over the region. Based on the emission flux of CO from various inventories and observed BC/CO ratios during pre-monsoon and winter, the BC emission for India is estimated to be in the range of 0.78-1.23 Tg year-1. The analysis of scavenging of BC revealed the loss rate of BC due to relative humidity 0.39 ± 0.08 ng m-3 ppb-1 RH (%)-1 over northern BoB and 0.53 ± 0.04 ng m-3 ppb-1 RH (%)-1 over the southern-BoB during winter.

  11. Chemical characteristics of aerosols in MABL of Bay of Bengal and Arabian Sea during spring inter-monsoon: A comparative study

    Indian Academy of Sciences (India)

    Ashwini Kumar; A K Sudheer; M M Sarin


    The chemical composition of aerosols in the Marine Atmospheric Boundary Layer (MABL) of Bay of Bengal (BoB) and Arabian Sea (AS) has been studied during the spring and inter-monsoon (March–May 2006) based on the analysis of water soluble constituents (Na+, NH$^{+}_{4}$, K+, Mg2+, Ca2+, Cl−, NO$^{−}_{3}$ and SO$^{2−}_{4}$), crustal elements (Al, Fe, and Ca) and carbonaceous species (EC, OC). The total suspended particulates (TSP) ranged from 5.2 to 46.6 g m−3 and 8.2 to 46.9 g m−3 during the sampling transects in the BoB and AS respectively. The water-soluble species, on average, accounted for 44% and 33% of TSP over BoB and AS respectively, with dominant contribution of SO$^{2−}_{4}$ over both the oceanic regions. However, distinct differences with respect to elevated abundances of NH$^{+}_{4}$ in the MABL of BoB and that of Na+ and Ca2+ in AS are clearly evident. The non-sea-salt component of SO$^{2−}_{4}$ ranging from 82 to 98% over BoB and 35 to 98% over AS; together with nss-Ca2+/nss-$SO^{2−}_{4}$ equivalent ratios 0.12 to 0.5 and 0.2 to 1.16, respectively, provide evidence for the predominance of anthropogenic constituents and chemical transformation processes occurring within MABL. The concentrations of OC and EC average around 1.9 and 0.4 g m−3 in BoB and exhibit a decreasing trend from north to south; however, abundance of these carbonaceous species are not significantly pronounced over AS. The abundance of Al, used as a proxy for mineral aerosols, varied from 0.2 to 1.9 g m−3 over BoB and AS, with a distinctly different spatial pattern – decreasing north to south in BoB in contrast to an increasing pattern in the Arabian Sea.

    A multiple round quantum dense coding scheme based on the quantum phase estimation algorithm is proposed and implemented in a three qubit nuclear magnetic resonance (NMR) quantum computer. Using an m + 1 qubit system, Bob can transmit one of 2m+1 messages to Alice, through manipulating only one qubit and exchanging it between Alice and Bob for m rounds. The information capacity is enhanced to m + 1 bits as compared to m bits in a classical scheme. The scheme has been demonstrated in NMR system, and the experimental results show a good agreement between theory and experiment.

  15. Teleportation of N-Particle Entangled GHZ State via Entanglement Swapping

    Institute of Scientific and Technical Information of China (English)

    SHA Jin-Qiao; FANG Jian-Xing; ZHU Shi-Qun; JIANG Wei-Xing; QIAN Xue-Min


    In this scheme, N non-maximally entangled particle pairs are used as quantum channel to teleport an unknown N-particle entangled GHZ state via entanglement swapping. In order to realize this teleportation, the sender Alice operates Bell-state measurement on particles belonging to herself. Then she informs the results to the receiver Bob through classical communication. According to the results, Bob operates corresponding transformation to reconstruct the initial state. The advantage of this scheme is that it needs only one common unitary matrix for Alice's different results, which has a more general meaning. As a special case, teleporting an unknown three-particle entangled GHZ state is proposed.

    Hemenway, Mary Kay; Jefferys, William H.; Lambert, David L.


    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

  5. Aiming at Targets: The Autobiography of Robert C. Seamans, Jr. (United States)

    Seamans, Robert C., Jr.


    Bob Seamans originally was inspired to write this book for his family and friends. That is a large audience. By his own count his immediate family numbers twenty-four, not counting brothers and cousins and their families. His friends are uncounted but surely run to hundreds. As one of them and as a colleague at NASA, I am pleased and honored that he asked me to write this foreword. While written in Bob's unique and informal style, this autobiography has significance for many readers beyond his large circles of family and friends. Leaders and students of large, complex technological endeavors should be able to learn much from reading how Bob faced the daunting technical and management challenges in his career. As the title of this book implies, Bob has always set high goals for himself and then kept his eyes focused on both the necessary details and the broader picture. His ability to shift smoothly among jobs that required seemingly disparate abilities and skills speaks volumes about his insight, dedication, and enthusiasm for achievement. The book spans a truly remarkable life story. Bob first takes us through his growing up, education, and early professional and family life. Next he focuses on the crucial years when he was the general manager of NASA. Then he moves on to his career in the top jobs at the Air Force, the National Academy of Engineering, and the Energy Research and Development Administration. Finally, he touches on his later leadership activities in the academic and business worlds. Aiming at Targets is a series of fascinating topical vignettes covering his professional life. Taken together, like broad brushstrokes in an impressionist painting, they give a better picture of Bob Seamans and his work than a detailed recitation of facts and dates could hope to do. This is a cheerful account of an interesting and successful career. The book is full of good stories, with many memorable characters. Like the proverbial sundial, it counts the sunny hours

  6. Distributed Oblivious Function Evaluation and Its Applications

    Institute of Scientific and Technical Information of China (English)

    Hong-Da Li; Xiong Yang; Deng-Guo Feng; Bao Li


    This paper is about distributed oblivious function evaluation (DOFE). In this setting one party (Alice) has a function f(x), and the other party (Bob) with an input α wants to learn f(α) in an oblivious way with the help of a set of servers. What Alice should do is to share her secret function f(x) among the servers. Bob obtains what he should get by interacting with the servers. This paper proposes the model and security requirements for DOFE and analyzes three distributed oblivious polynomial evaluation protocols presented in the paper.

  8. Teleportation of an arbitrary mixture of diagonal states of multiqudit

    Institute of Scientific and Technical Information of China (English)

    Du Qian-Hua; Lin Xiu-Min; Chen Zhi-Hua; Lin Gong-Wei; Chen Li-Bo; Gu Yong-Jian


    This paper proposes a scheme to teleport an arbitrary mixture of diagonal states of multiqutrit via classical correlation and classical communication. To teleport an arbitrary mixture of diagonal states of N qutrits, N classically correlated pairs of two qutrits are used as channel. The sender (Alice) makes Fourier transform and conditional gate (i.e., XOR(3) gate) on her qutrits and does measurement in appropriate computation bases. Then she sends N ctrits to the receiver (Bob). Based on the received information, Bob performs the corresponding unitary transformation on his qutrits and obtains the teleported state. Teleportation of an arbitrary mixture of diagonal states of multiqudit is also discussed.

  9. Probabilistic remote state preparation by W states

    Institute of Scientific and Technical Information of China (English)

    Liu Jin-Ming; Wang Yu-Zhu


    In this paper we consider a scheme for probabilistic remote state preparation of a general qubit by using W states. The scheme consists of the sender, Alice, and two remote receivers Bob and Carol. Alice performs a projective measurement on her qubit in the basis spanned by the state she wants to prepare and its orthocomplement. This allows either Bob or Carol to reconstruct the state with finite success probability. It is shown that for some special ensembles of qubits, the remote state preparation scheme requires only two classical bits, unlike the case in the scheme of quantum teleportation where three classical bits are needed.

  12. Probabilistic teleportation of an arbitrary GHZ-class state with a pure entangled two-particle quantum channel and its application in quantum state sharing

    Institute of Scientific and Technical Information of China (English)


    This paper presents a scheme for probabilistic teleportation of an arbitrary GHZ-class state with a pure entangled two-particle quantum channel. The sender Alice first teleports the coefficients of the unknown state to the receiver Bob, and then Bob reconstructs the state with an auxiliary particle and some unitary operations if the teleportation succeeds. This scheme has the advantage of transmitting much less particles for teleporting an arbitrary GHZ-class state than others. Moreover, it discusses the application of this scheme in quantum state sharing.

  19. High performance optical encryption based on computational ghost imaging with QR code and compressive sensing technique (United States)

    Zhao, Shengmei; Wang, Le; Liang, Wenqiang; Cheng, Weiwen; Gong, Longyan


    In this paper, we propose a high performance optical encryption (OE) scheme based on computational ghost imaging (GI) with QR code and compressive sensing (CS) technique, named QR-CGI-OE scheme. N random phase screens, generated by Alice, is a secret key and be shared with its authorized user, Bob. The information is first encoded by Alice with QR code, and the QR-coded image is then encrypted with the aid of computational ghost imaging optical system. Here, measurement results from the GI optical system's bucket detector are the encrypted information and be transmitted to Bob. With the key, Bob decrypts the encrypted information to obtain the QR-coded image with GI and CS techniques, and further recovers the information by QR decoding. The experimental and numerical simulated results show that the authorized users can recover completely the original image, whereas the eavesdroppers can not acquire any information about the image even the eavesdropping ratio (ER) is up to 60% at the given measurement times. For the proposed scheme, the number of bits sent from Alice to Bob are reduced considerably and the robustness is enhanced significantly. Meantime, the measurement times in GI system is reduced and the quality of the reconstructed QR-coded image is improved.

  20. Controlled remote implementation of partially unknown quantum operation

    Institute of Scientific and Technical Information of China (English)

    FAN QiuBo; LIU DongDong


    A protocol for controlled remote implementation of a partially unknown operation on an arbitrary quantum state is proposed. In this protocol, a task can be performed using a GHZ state shared among three distant parties: Alice, Bob and the controller Charlie. This protocol is also generalized to the multi-party control system based on sharing an N-qubit GHZ state.

  3. EDITORIAL: Stability and nonlinear dynamics of plasmas: A symposium celebrating Professor Robert Dewar's accomplishments in plasma physics Stability and nonlinear dynamics of plasmas: A symposium celebrating Professor Robert Dewar's accomplishments in plasma physics (United States)

    Bhattacharjee, Amitava


    To celebrate Professor Robert Dewar's 65th birthday, a Symposium was held on 31 October 2009 in Atlanta, Georgia, just before the 51st Annual Meeting of the Division of Plasma Physics of the American Physical Society. The Symposium was attended by many of Bob's colleagues, friends, postdoctoral colleagues and students (present and former). Boyd Blackwell, Anthony Cooper, Chris Hegna, Stuart Hudson, John Krommes, Alexander Pletzer, Ellen Zweibel, and I gave talks that covered various aspects of Bob's wide-ranging scholarship, and his leadership in the Australian and the US fusion program. At the Symposium, Bob gave an insightful talk, published in this issue as a paper with D Leykam. This paper makes available for the first time unpublished results from Bob's M Sc Thesis on a general method for calculating the potential around a `dressed' test particle in an isotropic and collisionless plasma. The paper is interesting not only because it provides a glimpse of the type of elegant applied mathematics that we have come to associate with Bob, but also because he discusses some leitmotifs in his intellectual evolution since the time he was a graduate student at the University of Melbourne and Princeton University. Through his early encounter with quantum field theory, Bob appreciated the power of Lagrangian and Hamiltonian formalisms, which he used with great effectiveness in nonlinear dynamics and plasma physics. A question that animates much of his work is one that underlies the `dressed' particle problem: if one is given a Hamiltonian with an unperturbed (or `bare') part and an interaction part, how is one to obtain a canonical transformation to `the oscillation centre' thatwould reduce the interaction part to an irreducible residual part while incorporating the rest in a renormalized zeroth-order Hamiltonian? One summer in Princeton, I worked with Bob on a possible variational formulation for this problem, and failed. I was daunted enough by my failure that I turned

  6. Quantum key distribution: vulnerable if imperfectly implemented (United States)

    Leuchs, G.


    We report several vulnerabilities found in Clavis2, the flagship quantum key distribution (QKD) system from ID Quantique. We show the hacking of a calibration sequence run by Clavis2 to synchronize the Alice and Bob devices before performing the secret key exchange. This hack induces a temporal detection efficiency mismatch in Bob that can allow Eve to break the security of the cryptosystem using faked states. We also experimentally investigate the superlinear behaviour in the single-photon detectors (SPDs) used by Bob. Due to this superlinearity, the SPDs feature an actual multi-photon detection probability which is generally higher than the theoretically-modelled value. We show how this increases the risk of detector control attacks on QKD systems (including Clavis2) employing such SPDs. Finally, we review the experimental feasibility of Trojan-horse attacks. In the case of Clavis2, the objective is to read Bob's phase modulator to acquire knowledge of his basis choice as this information suffices for constructing the raw key in the Scarani-Acin-Ribordy-Gisin 2004 (SARG04) protocol. We work in close collaboration with ID Quantique and for all these loopholes, we notified them in advance. Wherever possible, we or ID Quantique proposed countermeasures and they implemented suitable patches and upgrade their systems.

    In this series, the Bulletin aims to explain the role of the Ombuds at CERN by presenting practical examples of misunderstandings that could have been resolved by the Ombuds if he had been contacted earlier. Please note that, in all the situations we present, the names are fictitious and used only to improve clarity.   Bob* has been working at CERN for almost four years on a limited-duration contract. Due to the early retirement of one of his colleagues, he was appointed Section Leader very early in his career, as he was the only one who was able to replace this person. As Section Leader, Bob had to provide annual assessments for several staff members, which he did in a very honest and balanced way. When staff members were given their results from the MARS exercise, George – one of Bob’s supervisees – accused Bob of not giving him the promotion he deserved. George had been expecting his MARS appraisal to include work that he claims Bob, being under a limited-durati...

  11. Blind quantum computation over a collective-noise channel (United States)

    Takeuchi, Yuki; Fujii, Keisuke; Ikuta, Rikizo; Yamamoto, Takashi; Imoto, Nobuyuki


    Blind quantum computation (BQC) allows a client (Alice), who only possesses relatively poor quantum devices, to delegate universal quantum computation to a server (Bob) in such a way that Bob cannot know Alice's inputs, algorithm, and outputs. The quantum channel between Alice and Bob is noisy, and the loss over the long-distance quantum communication should also be taken into account. Here we propose to use decoherence-free subspace (DFS) to overcome the collective noise in the quantum channel for BQC, which we call DFS-BQC. We propose three variations of DFS-BQC protocols. One of them, a coherent-light-assisted DFS-BQC protocol, allows Alice to faithfully send the signal photons with a probability proportional to a transmission rate of the quantum channel. In all cases, we combine the ideas based on DFS and the Broadbent-Fitzsimons-Kashefi protocol, which is one of the BQC protocols, without degrading unconditional security. The proposed DFS-based schemes are generic and hence can be applied to other BQC protocols where Alice sends quantum states to Bob.

  16. Information Causality is a Special Point in the Dual of the Gray-Wyner Region

    CERN Document Server

    Beigi, Salman


    Information Causality contributes to the program of deriving fundamentals of quantum theory from information theoretic principles. It puts restrictions on the amount of information learned by a party (Bob) from the other party (Alice) in a one-way communication scenario as follows. Bob receives an index b, and after a one-way communication from Alice, tries to recover a part of Alice's input. Because of the possibility of cloning, this game in its completely classical form is equivalent to one in which there are several Bobs indexed by b, who are interested in recovering different parts of Alice's input string, after receiving a public message from her. Adding a private message from Alice to each Bob, and assuming that the game is played many times, we obtain the Gray-Wyner problem for which a complete characterization of the achievable region is known. In this paper, we first argue that in the classical case Information Causality is only a single point in the dual of the Gray-Wyner region. Next, we show that...

  19. Seasonal variability of salinity budget and water exchange in the northern Indian Ocean from HYCOM assimilation

    Institute of Scientific and Technical Information of China (English)

    ZHANG Yuhong; DU Yan


    Based on HYbrid Coordinate Ocean Model (HYCOM) assimilation and observations,we analyzed seasonal variability of the salinity budget in the southeastern Arabian Sea (AS) and the southern part of the Bay of Bengal (BOB),as well as water exchange between the two basins.Results show that fresh water flux cannot explain salinity changes in salinity budget of both regions.Oceanic advection decreases salinity in the southeastern AS during the winter monsoon season and increases salinity in the southern BOB during the summer monsoon season.In winter,the Northeast Monsoon Current (NMC) carries fresher water from the BOB westward into the southern AS; this westward advection is confined to 4°-6°N and the upper 180 m south of the Indian peninsula.Part of the less saline water then turns northward,decreasing salinity in the southeastern AS.In summer,the Southwest Monsoon Current (SMC) advects high-salinity water from the AS eastward into the BOB,increasing salinity along its path.This eastward advection of high-salinity water south of the India Peninsula extends southward to 2°N,and the layer becomes shallower than in winter.In addition to the monsoon current,the salinity difference between the two basins is important for salinity advection.

  4. Device-independent two-party cryptography secure against sequential attacks (United States)

    Kaniewski, Jędrzej; Wehner, Stephanie


    The goal of two-party cryptography is to enable two parties, Alice and Bob, to solve common tasks without the need for mutual trust. Examples of such tasks are private access to a database, and secure identification. Quantum communication enables security for all of these problems in the noisy-storage model by sending more signals than the adversary can store in a certain time frame. Here, we initiate the study of device-independent (DI) protocols for two-party cryptography in the noisy-storage model. Specifically, we present a relatively easy to implement protocol for a cryptographic building block known as weak string erasure and prove its security even if the devices used in the protocol are prepared by the dishonest party. DI two-party cryptography is made challenging by the fact that Alice and Bob do not trust each other, which requires new techniques to establish security. We fully analyse the case of memoryless devices (for which sequential attacks are optimal) and the case of sequential attacks for arbitrary devices. The key ingredient of the proof, which might be of independent interest, is an explicit (and tight) relation between the violation of the Clauser-Horne-Shimony-Holt inequality observed by Alice and Bob and uncertainty generated by Alice against Bob who is forced to measure his system before finding out Alice’s setting (guessing with postmeasurement information). In particular, we show that security is possible for arbitrarily small violation.

    Synthesizing data from several cruise experiments over the Bay of Bengal (BoB), the seasonal characterization of aerosol black carbon (BC) mass concentration was made. The study indicated that the BC mass concentration (MBC) showed significant seasonal variation over the oceanic region with MBC being the highest during the winter season (˜2407 ± 1756 ng m-3) and lowest in summer monsoon (˜765 ± 235 ng m-3). The seasonal changes in the BC mass concentration were more prominent over the northern BoB (having an annual amplitude of ˜4) compared to southern BoB (amplitude ˜ 2). Significant spatial gradients in MBC, latitudinal as well as longitudinal, existed in all the seasons. Latitudinal gradients, despite being consistently increasing northwards, were found to be sharper during winter and weakest during summer monsoon with e-fold scaling distances of ˜7.7° and ˜15.6° during winter and summer monsoon seasons respectively. Longitudinally, BC concentrations tend to increase toward east during winter and premonsoon seasons, but an opposite trend was seen in monsoon season highlighting the seasonally changing source impacts on BC loading over BoB. Examination of the results in light of possible role of transport from adjoining landmasses, using airmass back trajectory cluster analysis, also supported spatially and temporally varying source influence on oceanic region.

  9. Large-Capacity Three-Party Quantum Digital Secret Sharing Using Three Particular Matrices Coding (United States)

    Lai, Hong; Luo, Ming-Xing; Pieprzyk, Josef; Tao, Li; Liu, Zhi-Ming; Orgun, Mehmet A.


    In this paper, we develop a large-capacity quantum digital secret sharing (QDSS) scheme, combined the Fibonacci- and Lucas-valued orbital angular momentum (OAM) entanglement with the recursive Fibonacci and Lucas matrices. To be exact, Alice prepares pairs of photons in the Fibonacci- and Lucas-valued OAM entangled states, and then allocates them to two participants, say, Bob and Charlie, to establish the secret key. Moreover, the available Fibonacci and Lucas values from the matching entangled states are used as the seed for generating the Fibonacci and Lucas matrices. This is achieved because the entries of the Fibonacci and Lucas matrices are recursive. The secret key can only be obtained jointly by Bob and Charlie, who can further recover the secret. Its security is based on the facts that nonorthogonal states are indistinguishable, and Bob or Charlie detects a Fibonacci number, there is still a twofold uncertainty for Charlie' (Bob') detected value.

  20. An integrated campaign for investigation of winter-time continental haze over Indo-Gangetic Basin and its radiative effects. (United States)

    Das, Sanat Kumar; Chatterjee, Abhijit; Ghosh, Sanjay K; Raha, Sibaji


    An outflow of continental haze occurs from Indo-Gangetic Basin (IGB) in the North to Bay of Bengal (BoB) in the South. An integrated campaign was organized to investigate this continental haze during December 2013-February 2014 at source and remote regions within IGB to quantify its radiative effects. Measurements were carried out at three locations in eastern India; 1) Kalas Island, Sundarban (21.68°N, 88.57°E) - an isolated island along the north-east coast of BoB, 2) Kolkata (22.57°N, 88.42°E) - an urban metropolis and 3) Siliguri (26.70°N, 88.35°E) - an urban region at the foothills of eastern Himalayas. Ground-based AOD (at 0.5 μm) is observed to be maximum (1.25±0.18) over Kolkata followed by Siliguri (0.60±0.17) and minimum over Sundarban (0.53±0.18). Black carbon concentration is found to be maximum at Kolkata (21.6±6.6 μg·m(-3)) with almost equal concentrations at Siliguri (12.6±5.2 μg·m(-3)) and Sundarban (12.3±3.0 μg·m(-3)). Combination of MODIS-AOD and back-trajectories analysis shows an outflow of winter-time continental haze originating from central IGB and venting out through Sundarban towards BoB. This continental haze with high extinction coefficient is identified up to central BoB using CALIPSO observations and is found to contribute ~75% to marine AOD over central BoB. This haze produces significantly high aerosol radiative forcing within the atmosphere over Kolkata (75.4 Wm(-2)) as well as over Siliguri and Sundarban (40 Wm(-2)) indicating large forcing over entire IGB, from foothills of the Himalayas to coastal region. This winter-time continental haze also causes about similar radiative heating (1.5 K·day(-1)) from Siliguri to Sundarban which is enhanced over Kolkata (3 K·day(-1)) due to large emission of local urban aerosols. This high aerosol heating over entire IGB and coastal region of BoB can have considerable impact on the monsoonal circulation and more importantly, such haze transported over to BoB can significantly

  1. Extremely large anthropogenic-aerosol contribution to total aerosol load over the Bay of Bengal during winter season

    Full Text Available Ship-borne observations of spectral aerosol optical depth (AOD have been carried out over the entire Bay of Bengal (BoB as part of the W-ICARB cruise campaign during the period 27 December 2008–30 January 2009. The results reveal a pronounced temporal and spatial variability in the optical characteristics of aerosols mainly due to anthropogenic emissions and their dispersion controlled by local meteorology. The highest aerosol amount, with mean AOD500>0.4, being even above 1.0 on specific days, is found close to the coastal regions in the western and northern parts of BoB. In these regions the Ångström exponent is also found to be high (~1.2–1.25 indicating transport of strong anthropogenic emissions from continental regions, while very high AOD500 (0.39±0.07 and α380–870 values (1.27±0.09 are found over the eastern BoB. Except from the large α380–870 values, an indication of strong fine-mode dominance is also observed from the AOD curvature, which is negative in the vast majority of the cases, suggesting dominance of an anthropogenic-pollution aerosol type. On the other hand, clean maritime conditions are rather rare over the region, while the aerosol types are further examined through a classification scheme based on the relationship between α and dα. It was found that even for the same α values the fine-mode dominance is larger for higher AODs showing the strong continental influence over the marine environment of BoB. Furthermore, there is also an evidence of aerosol-size growth under more turbid conditions indicative of coagulation and/or humidification over specific BoB regions. The results obtained using OPAC model show significant fraction of soot aerosols (~6 %–8 % over the eastern and northwestern BoB, while coarse-mode sea salt particles are found to dominate in the southern parts of BoB.

  2. Changes in water vapor transport during the Meiyu season after 2000 and their relationship with the Indian ocean SST and Pacific-Japan pattern (United States)

    Gao, Qingjiu; Sun, Yuting


    Euler's method of water vapor analysis and the Lagrangian trajectory analysis for 1979-2009 show the water vapor associated with Meiyu rainfall over the Yangtze-Huaihe River Valley (YHRV) mainly comes from the South China Sea (SCS) and the Bay of Bengal (BOB), and the local evaporation from the lower and middle troposphere over the Pacific Ocean and Eurasia are secondary. Compared with that before 2000, the contribution of water vapor from the BOB to Meiyu rainfall doubles in the low level but decreases in the mid-level after 2000, while that from the SCS decreases and mid-level transport path shifts to north of the Indochina Peninsula. The increased water vapor transport from the BOB and north of the Indochina Peninsula is the primary cause for the water vapor budget increase at the southern boundary of the YHRV. It is further noted that the water vapor from the SCS mainly influences precipitation over the region to the south of the mid-lower reaches of the Yangtze River, while water vapor transport from the BOB can cause opposite rainfall variations between north and south of Yangtze River over Meiyu rainfall region. After 2000, the decreased/increased SCS/BOB water vapor transport jointly influences the Meiyu rain belt shift northward. Singular value decomposition is used to study the relationship of changes in the water vapor transport with the Indian Ocean sea surface temperature (SST) and Pacific-Japan (P-J) pattern. Enhancement of the coupling between the Indian Ocean SST basin-wide warming and P-J pattern is an inner mechanism of the changes in water vapor transport and the northward shift of the rain belt.

  3. Possible role of pre-monsoon sea surface warming in driving the summer monsoon onset over the Bay of Bengal (United States)

    Li, Kuiping; Liu, Yanliang; Yang, Yang; Li, Zhi; Liu, Baochao; Xue, Liang; Yu, Weidong


    Sea surface temperature (SST) reaches its annual maximum just before the summer monsoon onset and collapses soon after in the central areas of the Bay of Bengal (BoB). Here, the impact of the peak in the pre-monsoon SST on triggering the earliest monsoon onset in the BoB is investigated, with a focus on the role they play in driving the first-branch northward-propagating intra-seasonal oscillations (FNISOs) over the equatorial Eastern Indian Ocean (EIO). During the calm pre-monsoon period, sea surface warming in the BoB could increase the surface equivalent potential temperature (θe) in several ways. Firstly, warming of the sea surface heats the surface air through sensible heating, which forces the air temperature to follow the SST. The elevated air surface temperature accounts for 30 % of the surface θe growth. Furthermore, the elevated air temperature raises the water vapor capacity of the surface air to accommodate more water vapor. Constrained by the observation that the surface relative humidity is maintained nearly constant during the monsoon transition period, the surface specific humidity exhibits a significant increase, according to the Clausius-Clapeyron relationship. Budget analysis indicates that the additional moisture is primarily obtained from sea surface evaporation, which also exhibits a weak increasing trend due to the sea surface warming. In this way, it contributes about 70 % to the surface θe growth. The rapid SST increase during the pre-monsoon period preconditions the summer monsoon onset over the BoB through its contributions to significantly increase the surface θe, which eventually establishes the meridional asymmetry of the atmospheric convective instability in the EIO. The pre-established greater convective instability leads to the FNISO convections, and the summer monsoon is triggered in the BoB region.

  5. Thermally stable hyperbranched polyether-based polymer electrolyte for lithium-ion batteries (United States)

    Wu, Feng; Feng, Ting; Wu, Chuan; Bai, Ying; Ye, Lin; Chen, Junzheng


    A thermally stable polymer matrix, comprising hyperbranched polyether PHEMO (poly(3-{2-[2-(2-hydroxyethoxy) ethoxy] ethoxy}methyl-3'-methyloxetane)) and PVDF-HFP (poly(vinylidene fluoride-hexafluoropropylene)), has been successfully prepared for applications in lithium-ion batteries. This type of polymer electrolyte has been made by adding different amounts of lithium bis(oxalate)borate (LiBOB) to the polymer matrix. Its thermal and structural properties were measured using differential scanning calorimetry and x-ray diffraction. Experimental results show that the polymer electrolyte system possesses good thermal stability, with a decomposition temperature above 420 °C. The ionic conductivity of the polymer electrolyte system is dependent on the lithium salt content, reaching a maximum of 1.1 × 10-5 S cm-1 at 30 °C and 2.3 × 10-4 S cm-1 at 80 °C when doped with 10 wt% LiBOB.

  6. Effect of aging on the ionic conductivity of polyvinylidenefluoride-hexafluoropropylene (PVdF-HFP) membrane impregnated with different lithium salts (United States)

    Aravindan, Vanchiappan; Vickraman, Palanisamy


    The aging towards the ionic conductivity have been studied using of different lithium salts namely, lithium bis(oxalate)borate (LiBOB), lithium difluoro(oxalato)borate (LiDFOB), lithium fluoroalkylphosphate (LiFAP) and LiPF6 in polyvinylidenefluoride-hexafluoropropylene (PVdF-HFP) matrix. The crystallization behavior of LiBOB and LiDFOB has been noticed for the first time during storage of such membranes within the texture of PVdF-HFP matrix. At the same time, such behavior has not been observed in the case of LiFAP and LiPF6 based membranes. The growth of such crystallites would certainly hinder the mobility mechanism of Li+ ions and it has been confirmed by ionic conductivity measurements. The formation of such crystals has been validated through scanning electron microscopic studies.

  7. Robust Anti-Collective Noise Quantum Secure Direct Dialogue Using Logical Bell States (United States)

    Wu, Di; Lv, Hong-Jun; Xie, Guang-Jun


    In this paper we propose two quantum secure direct dialogue (QSDD) schemes with logical Bell states which can resist collective noise. The two users Alice and Bob encode their secret messages with the help of unitary operations. Compared with many quantum secure direct communication (QSDC), there is no strict information sender and receiver in these schemes, one logical Bell state can be operated twice by Alice and Bob based on what messages they prefer to encode. As a result, the two users are able to share their messages mutually, so the efficiency of communication is improved. By rearranging the order of particles and inserting decoy photons, our protocols are able to avoid the information leakage and detect eavesdropping, and they can be proved to have unconditional security.

  8. Teleportation-based continuous variable quantum cryptography (United States)

    Luiz, F. S.; Rigolin, Gustavo


    We present a continuous variable (CV) quantum key distribution (QKD) scheme based on the CV quantum teleportation of coherent states that yields a raw secret key made up of discrete variables for both Alice and Bob. This protocol preserves the efficient detection schemes of current CV technology (no single-photon detection techniques) and, at the same time, has efficient error correction and privacy amplification schemes due to the binary modulation of the key. We show that for a certain type of incoherent attack, it is secure for almost any value of the transmittance of the optical line used by Alice to share entangled two-mode squeezed states with Bob (no 3 dB or 50% loss limitation characteristic of beam splitting attacks). The present CVQKD protocol works deterministically (no postselection needed) with efficient direct reconciliation techniques (no reverse reconciliation) in order to generate a secure key and beyond the 50% loss case at the incoherent attack level.

Our general model is as follows: two computationally unrestricted players, Alice and Bob, each have s(n) bits of memory....... When a player receives a bit of communication, he "compresses" his state. This compression may be an arbitrary function of his current memory contents, his input, and the bit of communication just received; the only restriction is that the compression must return at most s(n) bits. We obtain memory...... controls two types of memory: (i) a large, oblivious memory, where updates are only a function of the received bit and the current memory content, and (ii) a smaller, non-oblivious/general memory, where updates can be a function of the input given to Bob. We exhibit natural protocols where this semi...

  10. Security Weaknesses in Arbitrated Quantum Signature Protocols (United States)

    Liu, Feng; Zhang, Kejia; Cao, Tianqing


    Arbitrated quantum signature (AQS) is a cryptographic scenario in which the sender (signer), Alice, generates the signature of a message and then a receiver (verifier), Bob, can verify the signature with the help of a trusted arbitrator, Trent. In this paper, we point out there exist some security weaknesses in two AQS protocols. Our analysis shows Alice can successfully disavow any of her signatures by a simple attack in the first protocol. Furthermore, we study the security weaknesses of the second protocol from the aspects of forgery and disavowal. Some potential improvements of this kind of protocols are given. We also design a new method to authenticate a signature or a message, which makes AQS protocols immune to Alice's disavowal attack and Bob's forgery attack effectively.

    As a new model for signing quantum messages, arbitrated quantum signature (AQS) has recently received a lot of attention. In this paper we study the cryptanalysis of previous AQS protocols from the aspects of forgery and disavowal. We show that in these protocols the receiver, Bob, can realize existential forgery of the sender's signature under known message attack. Bob can even achieve universal forgery when the protocols are used to sign a classical message. Furthermore, the sender, Alice, can successfully disavow any of her signatures by simple attack. The attack strategies are described in detail and some discussions about the potential improvements of the protocols are given. Finally we also present several interesting topics on AQS protocols that can be studied in future.

On the way, we find out that a dog - much like a cat - can be both dead and alive, the gaze of a mouse can change the universe, and a comic book can actually make quantum physics fun, easy to understand and downright enchanting.

  14. Quantum hacking of a continuous-variable quantum-key-distribution system using a wavelength attack (United States)

    Huang, Jing-Zheng; Weedbrook, Christian; Yin, Zhen-Qiang; Wang, Shuang; Li, Hong-Wei; Chen, Wei; Guo, Guang-Can; Han, Zheng-Fu


    The security proofs of continuous-variable quantum key distribution are based on the assumptions that the eavesdropper can neither act on the local oscillator nor control Bob's beam splitter. These assumptions may be invalid in practice due to potential imperfections in the implementations of such protocols. In this paper, we consider the problem of transmitting the local oscillator in a public channel and propose a wavelength attack which allows the eavesdropper to control the intensity transmission of Bob's beam splitter by switching the wavelength of the input light. Specifically we target continuous-variable quantum key distribution systems that use the heterodyne detection protocol using either direct or reverse reconciliation. Our attack is proved to be feasible and renders all of the final keys shared between the legitimate parties insecure, even if they have monitored the intensity of the local oscillator. To prevent our attack on commercial systems, a simple wavelength filter should be randomly added before performing monitoring detection.

  15. Teleportation of the one-qubit state with environment-disturbed recovery operations

    CERN Document Server

    Hu, Ming-Liang


    We study standard protocol $\\mathcal{P}_0$ for teleporting the one-qubit state with both the transmission process of the two qubits constitute the quantum channel and the recovery operations performed by Bob disturbed by the decohering environment. The results revealed that Bob's imperfect operations do not eliminate the possibility of nonclassical teleportation fidelity provided he shares an ideal channel state with Alice, while the transmission process is constrained by a critical time $t_{0,c}$ longer than which will result in failure of $\\mathcal{P}_0$ if the two qubits are corrupted by the decohering environment. Moreover, we found that under the condition of the same decoherence rate $\\gamma$, the teleportation protocol is significantly more fragile when it is executed under the influence of the noisy environment than those under the influence of the dissipative and dephasing environments.

La clé est codée dans l'instant de détection des photons chez Bob. Une mesure de la durée de cohérence par moyen interférométrique permet d'assurer un fonctionnement en régime quantique. Nous avons mesuré un taux d'erreur quantique de 3.3% et une chute relative de contraste de l'interféromètre de 8.4%. Ces valeurs permettent d'évaluer un avantage d'information de 0.49 bit/impulsion pour Alice et Bob par rapport à un espion éventuel.

    Lunghi, T; Kaniewski, J; Bussières, F; Houlmann, R; Tomamichel, M; Kent, A; Gisin, N; Wehner, S; Zbinden, H


    Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a secret bit to Alice. Perfectly secure bit commitment between two mistrustful parties is impossible through asynchronous exchange of quantum information. Perfect security is however possible when Alice and Bob split into several agents exchanging classical and quantum information at times and locations suitably chosen to satisfy specific relativistic constraints. Here we report on an implementation of a bit commitment protocol using quantum communication and special relativity. Our protocol is based on [A. Kent, Phys. Rev. Lett. 109, 130501 (2012)] and has the advantage that it is practically feasible with arbitrary large separations between the agents in order to maximize the commitment time. By positioning agents in Geneva and Singapore, we obtain a commitment time of 15 ms. A security analysis considering experimental imperfections and finite statistics is presented.

  18. Quantum Decoys

    CERN Document Server

    Arrighi, P


    Alice communicates with words drawn uniformly amongst $\\{\\ket{j}\\}_{j=1..n}$, the canonical orthonormal basis. Sometimes however Alice interleaves quantum decoys $\\{\\frac{\\ket{j}+i\\ket{k}}{\\sqrt{2}}\\}$ between her messages. Such pairwise superpositions of possible words cannot be distinguished from the message words. Thus as malevolent Eve observes the quantum channel, she runs the risk of damaging the superpositions (by causing a collapse). At the receiving end honest Bob, whom we assume is warned of the quantum decoys' distribution, checks upon their integrity with a measurement. The present work establishes, in the case of individual attacks, the tradeoff between Eve's information gain (her chances, if a message word was sent, of guessing which) and the disturbance she induces (Bob's chances, if a quantum decoy was sent, to detect tampering). Besides secure channel protocols, quantum decoys seem a powerful primitive for constructing n-dimensional quantum cryptographic applications. Moreover the methods emp...

  19. Dynamics of Entropy in Quantum-like Model of Decision Making (United States)

    Basieva, Irina; Khrennikov, Andrei; Asano, Masanari; Ohya, Masanori; Tanaka, Yoshiharu


    We present a quantum-like model of decision making in games of the Prisoner's Dilemma type. By this model the brain processes information by using representation of mental states in complex Hilbert space. Driven by the master equation the mental state of a player, say Alice, approaches an equilibrium point in the space of density matrices. By using this equilibrium point Alice determines her mixed (i.e., probabilistic) strategy with respect to Bob. Thus our model is a model of thinking through decoherence of initially pure mental state. Decoherence is induced by interaction with memory and external environment. In this paper we study (numerically) dynamics of quantum entropy of Alice's state in the process of decision making. Our analysis demonstrates that this dynamics depends nontrivially on the initial state of Alice's mind on her own actions and her prediction state (for possible actions of Bob.)

  20. The Rain Keeps Falling

    Directory of Open Access Journals (Sweden)

    Deborah Rose


    Full Text Available The force of disaster hit me in the heart when, as a young woman, I heard Bob Dylan sing ‘Hard Rain’. In a voice stunned by violence, the young man reports on a multitude of forces that drag the world into catastrophe. In the 1960s I heard the social justice in the song. In 2004 the environmental issues ambush me. The song starts and ends in the dying world of trees and rivers. The poet’s words in both domains of justice are eerily prophetic. They call across the music, and across the years, saying that a hard rain is coming. The words bear no story at all; they give us a series of compelling images, an account of impending calamity. The artistry of the poet—Bob (Billy Boy Dylan—offers sequences of reports that, like Walter Benjamin’s storm from paradise, pile wreckage upon wreckage.

  2. The Impossibility of Pseudo-Telepathy Without Quantum Entanglement

    CERN Document Server

    Galliard, V; Tapp, A; Galliard, Viktor; Wolf, Stefan; Tapp, Alain


    Imagine that Alice and Bob, unable to communicate, are both given a 16-bit string such that the strings are either equal, or they differ in exactly 8 positions. Both parties are then supposed to output a 4-bit string in such a way that these short strings are equal if and only if the original longer strings given to them were equal as well. It is known that this task can be fulfilled without failure and without communication if Alice and Bob share 4 maximally entangled quantum bits. We show that, on the other hand, they CANNOT win the same game with certainty if they only share classical bits, even if it is an unlimited number. This means that for fulfilling this particular distributed task, quantum entanglement can completely replace communication. This phenomenon has been called pseudo-telepathy. The results of this paper complete the analysis of the first proposed game of this type between two players.

  3. Bidirectional and Asymmetric Controlled Quantum Information Transmission via Five-qubit Brown State (United States)

    Fang, Sheng-hui; Jiang, Min


    We put forward a new protocol of deterministic controlled bidirectional quantum information transmission, using a five-qubit Brown state. That is to say Alice wants to teleport an arbitrary single-qubit state to Bob and Bob wants to remotely prepare a known state for Alice via the control of the supervisor Charlie. In terms of physical implementations, only a CNOT gate, one Bell-state measurement and one qubit measurement are used in our protocol. Compared with previous study for solely bidirectional quantum teleportation and solely bidirectional remote state preparation schemes, our protocol is a kind of hybrid approach of information communication which makes the quantum channel multipurpose, i.e., no matter whether the transmitted state is known or unknown, the state information can be transmitted with each other via a five-qubit Brown state under the control of the third party as a supervisor.

    In this paper, we present an evaluation of the hybrid best-of-breed automated VHA (Veteran's Health Administration) clinical text de-identification system, nicknamed BoB, developed within the VHA Consortium for Healthcare Informatics Research. We also evaluate two available machine learning-based text de-identifications systems: MIST and HIDE. Two different clinical corpora were used for this evaluation: a manually annotated VHA corpus, and the 2006 i2b2 de-identification challenge corpus. These experiments focus on the generalizability and portability of the classification models across different document sources. BoB demonstrated good recall (92.6%), satisfactorily prioritizing patient privacy, and also achieved competitive precision (83.6%) for preserving subsequent document interpretability. MIST and HIDE reached very competitive results, in most cases with high precision (92.6% and 93.6%), although recall was sometimes lower than desired for the most sensitive PHI categories.

  5. Measurement of marine productivity using 15N and 13C tracers: Some methodological aspects

    Various experiments involving the measurement of new, regenerated and total productivity using 15N and 13C tracers were carried out in the Bay of Bengal (BOB) and in the Arabian Sea. Results from 15N tracer experiments indicate that nitrate uptake can be underestimated by experiments with incubation time > 4 hours. Indirect evidence suggests pico- and nano-phytoplankton, on their dominance over microphytoplankton, can also influence the f-ratios. Difference in energy requirement for assimilation of different nitrogen compounds decides the preferred nitrogen source during the early hours of incubation. Variation in light intensity during incubation also plays a significant role in the assimilation of nitrogen. Results from time course experiments with both 15N and 13C tracers suggest that photoinhibition appears significant in BOB and the Arabian Sea during noon. A significant correlation has been found in the productivity values obtained using 15N and 13C tracers.

    In situ buoy observation data spanning four years (2008-2011) were used to demonstrate the year-to-year variations of the monsoon onset processes in the Bay of Bengal (BOB). A significant early (late) monsoon onset event in 2009 (2010) was analyzed in detail. It is found that the year-to-year variations of monsoon onset can be attributed to either the interannual variability in the BoB SST or the irregular activities of the intra-seasonal oscillation (ISO). This finding raises concern over the potential difficulties in simulating or predicting the monsoon onset in the BoB region. This uncertainty largely comes from the unsatisfactory model behavior at the intra-seasonal time scale.

But as he found out,first impressions aren't always true. ""When I saw western China, I got confused; the economic situation there is completely different from that of the capital.I really wonder what the true state of the Chinese economy is."" Bob is not alone.The Chinese economy has become the subject of much global debate. In 2004, the Chinese central government carried out a national economic census covering Chinese business and industry.Its aim was to collect a comprehensive range of accurate economic data in order to get a clearer picture of the country's economic make-up.

  8. A new representation and probabilistic teleportation of an arbitrary and unknown N-particle state

    Institute of Scientific and Technical Information of China (English)

    Dong Li; Xiu Xiao-Ming; Gao Ya-Jun


    A new representation of an arbitrary and unknown N-particle state is presented at first. As an application,a scheme for teleporting an arbitrary and unknown N-particle state is proposed when N pairs of two-particle nonmaximally entangled states are utilized as quantum channels. After Alice (sender) makes Bell-state measurement on her particles, Bob (recipient) introduces an auxiliary particle and carries out appropriate unitary transformation on his particle and the auxiliary particle depending on classical information from Alice. Then, yon Neumann measurement that confirms whether the teleportation succeeds or not is performed by Bob on the auxiliary particle. In order to complete the teleportation, another N-1 times operations need to be performed which are similar to the above ones. It can be successfully realized with a certain probability which is determined by the product of the smaller coefficients of non-maximally entangled pairs. All possible unitary transformations are given in detail.

  9. Two-Player 2 × 2 Quantum Game in Spin System (United States)

    Huang, Zhiming; Situ, Haozhen


    In this work, we study the payoffs of quantum Samaritan's dilemma played with the thermal entangled state of XXZ spin model in the presence of Dzyaloshinskii-Moriya (DM) interaction. We discuss the effect of anisotropy parameter, strength of DM interaction and temperature on quantum Samaritan's dilemma. It is shown that although increasing DM interaction and anisotropy parameter generate entanglement, players payoffs are not simply decided by entanglement and depend on other game components such as strategy and payoff measurement. In general, Entanglement and Alice's payoff evolve to a relatively stable value with anisotropy parameter, and develop to a fixed value with DM interaction strength, while Bob's payoff changes in the reverse direction. It is noted that the augment of Alice's payoff compensates for the loss of Bob's payoff. For different strategies, payoffs have different changes with temperature. Our results and discussions can be analogously generalized to other 2 × 2 quantum static games in various spin models.

  10. Randomization for Security in Half-Duplex Two-Way Gaussian Channels

    Gamal, Aly El; Gamal, Hesham El


    This paper develops a new physical layer framework for secure two-way wireless communication in the presence of a passive eavesdropper, i.e., Eve. Our approach achieves perfect information theoretic secrecy via a novel randomized scheduling and power allocation scheme. The key idea is to allow Alice and Bob to send symbols at random time instants. While Alice will be able to determine the symbols transmitted by Bob, Eve will suffer from ambiguity regarding the source of any particular symbol. This desirable ambiguity is enhanced, in our approach, by randomizing the transmit power level. Our theoretical analysis, in a 2-D geometry, reveals the ability of the proposed approach to achieve relatively high secure data rates under mild conditions on the spatial location of Eve. These theoretical claims are then validated by experimental results using IEEE 802.15.4-enabled sensor boards in different configurations, motivated by the spatial characteristics of Wireless Body Area Networks (WBAN).

  11. Interference-free coulometric titration of water in lithium bis(oxalato)borate using Karl Fischer reagents based on N-methylformamide. (United States)

    Larsson, William; Panitz, Jan-Christoph; Cedergren, Anders


    A non-alcoholic coulometric reagent based on N-methylformamide (NMF) was shown to eliminate the severe interference effect caused by the alcohol component of the conventional Karl Fischer (KF) reagent on the battery electrolyte lithium bis(oxalato)borate (LiBOB). For sample amounts up to 240 microg of water, the stoichiometry of the KF reaction deviated only slightly from the ideal 1:1 ratio for the best reagent composition. Both solid and dissolved (in acetonitrile, tetrahydrofuran (THF), and ethylene carbonate/ethyl methyl carbonate) LiBOB were titrated successfully using a Metrohm 756 KF Coulometer with a diaphragm cell. The detection limit was estimated to be 0.5-1 microg of water using 100ml of reagent in this system.

  12. The operational meaning of quantum conditional information

    Devetak, I; Devetak, Igor; Yard, Jon


    With a statistical view towards information and noise, information theory derives ultimate limitations on information processing tasks. These limits are generally expressed in terms of entropic measures of information and correlations. Here we answer the quantum information-theoretic question: ``How correlated are two quantum systems from the perspective of a third?" by solving the following `quantum state redistribution' problem. Given an arbitrary quantum state of three systems, where Alice holds two and Bob holds one, what is the cost, in terms of quantum communication and entanglement, for Alice to give one of her parts to Bob? The communication cost gives the first operational interpretation to quantum conditional mutual information. The optimal procedure is self-dual under time reversal and is perfectly composable. This generalizes known protocols such as the state merging and fully quantum Slepian-Wolf protocols, from which almost every known protocol in quantum Shannon theory can be derived.

  13. Secure quantum communication using classical correlated channel (United States)

    Costa, D.; de Almeida, N. G.; Villas-Boas, C. J.


    We propose a secure protocol to send quantum information from one part to another without a quantum channel. In our protocol, which resembles quantum teleportation, a sender (Alice) and a receiver (Bob) share classical correlated states instead of EPR ones, with Alice performing measurements in two different bases and then communicating her results to Bob through a classical channel. Our secure quantum communication protocol requires the same amount of classical bits as the standard quantum teleportation protocol. In our scheme, as in the usual quantum teleportation protocol, once the classical channel is established in a secure way, a spy (Eve) will never be able to recover the information of the unknown quantum state, even if she is aware of Alice's measurement results. Security, advantages, and limitations of our protocol are discussed and compared with the standard quantum teleportation protocol.

  14. A Weak Quantum Blind Signature with Entanglement Permutation (United States)

    Lou, Xiaoping; Chen, Zhigang; Guo, Ying


    Motivated by the permutation encryption algorithm, a weak quantum blind signature (QBS) scheme is proposed. It involves three participants, including the sender Alice, the signatory Bob and the trusted entity Charlie, in four phases, i.e., initializing phase, blinding phase, signing phase and verifying phase. In a small-scale quantum computation network, Alice blinds the message based on a quantum entanglement permutation encryption algorithm that embraces the chaotic position string. Bob signs the blinded message with private parameters shared beforehand while Charlie verifies the signature's validity and recovers the original message. Analysis shows that the proposed scheme achieves the secure blindness for the signer and traceability for the message owner with the aid of the authentic arbitrator who plays a crucial role when a dispute arises. In addition, the signature can neither be forged nor disavowed by the malicious attackers. It has a wide application to E-voting and E-payment system, etc.

  15. Perfect commuting-operator strategies for linear system games (United States)

    Cleve, Richard; Liu, Li; Slofstra, William


    Linear system games are a generalization of Mermin's magic square game introduced by Cleve and Mittal. They show that perfect strategies for linear system games in the tensor-product model of entanglement correspond to finite-dimensional operator solutions of a certain set of non-commutative equations. We investigate linear system games in the commuting-operator model of entanglement, where Alice and Bob's measurement operators act on a joint Hilbert space, and Alice's operators must commute with Bob's operators. We show that perfect strategies in this model correspond to possibly infinite-dimensional operator solutions of the non-commutative equations. The proof is based around a finitely presented group associated with the linear system which arises from the non-commutative equations.

  16. Quantum locking of classical correlations and quantum discord of classical-quantum states

    CERN Document Server

    Boixo, S; Cavalcanti, D; Modi, K; Winter, A


    A locking protocol between two parties is as follows: Alice gives an encrypted classical message to Bob which she does not want Bob to be able to read until she gives him the key. If Alice is using classical resources, and she wants to approach unconditional security, then the key and the message must have comparable sizes. But if Alice prepares a quantum state, the size of the key can be comparatively negligible. This effect is called quantum locking. Entanglement does not play a role in this quantum advantage. We show that, in this scenario, the quantum discord quantifies the advantage of the quantum protocol over the corresponding classical one for any classical-quantum state.

  17. Ice berg cracking events as identified from underwater ambient noise measurements in the shallow waters of Ny-Alesund, Arctic (United States)

    Ashokan, M.; Latha, G.; Thirunavukkarasu, A.; Raguraman, G.; Venkatesan, R.


    This paper presents the work carried out on the analysis of preliminary underwater ambient noise measurements in the shallow waters of Kongsfjorden fjord, Arctic in the summer season, in which the ice berg cracking noise is identified. In the summer period, the melting of ice cover is fast and hence the ice bergs are free to move and float in the ocean. Underwater ambient noise has been acquired in the Kongsfjorden fjord, Arctic sea on 19th July 2015 at 5 m water depth, where the ocean depth is 50 m. Due to the tensile cracks at the surface of the sea ice by thermal expansion, ice berg calving and bobbing occurred near the experiment site. Analysis of power spectra shows that ice berg calving noise falls in the frequency band 100 Hz-500 Hz and the ice berg bobbing noise falls in the frequency band 200 Hz-400 Hz.

  18. An Operator--like Description of Love Affairs

    CERN Document Server

    Bagarello, Fabio


    We adopt the so--called \\emph{occupation number representation}, originally used in quantum mechanics and recently considered in the description of stock markets, in the analysis of the dynamics of love relations. We start with a simple model, involving two actors (Alice and Bob): in the linear case we obtain periodic dynamics, whereas in the nonlinear regime either periodic or quasiperiodic solutions are found. Then we extend the model to a love triangle involving Alice, Bob and a third actress, Carla. Interesting features appear, and in particular we find analytical conditions for the linear model of love triangle to have periodic or quasiperiodic solutions. Numerical solutions are exhibited in the nonlinear case.

  20. Device-independent two-party cryptography secure against sequential attacks

    DEFF Research Database (Denmark)

    Kaniewski, Jedrzej; Wehner, Stephanie


    The goal of two-party cryptography is to enable two parties, Alice and Bob, to solve common tasks without the need for mutual trust. Examples of such tasks are private access to a database, and secure identification. Quantum communication enables security for all of these problems in the noisy......-storage model by sending more signals than the adversary can store in a certain time frame. Here, we initiate the study of device-independent (DI) protocols for two-party cryptography in the noisy-storage model. Specifically, we present a relatively easy to implement protocol for a cryptographic building block...... known as weak string erasure and prove its security even if the devices used in the protocol are prepared by the dishonest party. DI two-party cryptography is made challenging by the fact that Alice and Bob do not trust each other, which requires new techniques to establish security. We fully analyse...

  1. Timelike information broadcasting in cosmology

    CERN Document Server

    Blasco, Ana; Martin-Benito, Mercedes; Martin-Martinez, Eduardo


    We study the transmission of information and correlations through quantum fields in cosmological backgrounds. With this aim, we make use of quantum information tools to quantify the classical and quantum correlations induced by a quantum massless scalar field in two particle detectors, one located in the early universe (Alice's) and the other located at a later time (Bob's). In particular, we focus on two phenomena: a) the consequences on the transmission of information of the violations of the strong Huygens principle for quantum fields, and b) the analysis of the field vacuum correlations via correlation harvesting from Alice to Bob. We will study a standard cosmological model first and then assess whether these results also hold if we use other than the general relativistic dynamics. As a particular example, we will study the transmission of information through the Big Bounce, that replaces the Big Bang, in the effective dynamics of Loop Quantum Cosmology.

    We investigate the quantum teleportation between a conformal detector Alice and an inertial detector Bob in de Sitter space in two schemes, (i) one uses free scalar modes and (ii) one utilizes cavity to store qubit. We show that the fidelity of the teleportation is degraded for Bob in both cases. While the fidelity-loss is due to the Gibbons–Hawking effect associated with his cosmological horizon in the scheme (i), the entanglement decreases in the scheme (ii) because the ability to entangle the cavities is reduced by the spacetime curvature. With a cutoff at Planck-scale, comparing with the standard Bunch–Davies choice, we also show that the possible Planckian physics cause extra modifications to the fidelity of the teleportation protocol in both schemes.

    Lee, H; Lee, D; Lim, J; Yang, H J; Lee, Hwayean; Lee, Sangjin; Lee, Donghoon; Lim, Jongin; Yang, HyungJin


    We propose a quantum key distribution protocol with quantum based user authentication. User authentication is executed by validating the correlation of GHZ states. Alice and Bob can distribute a secure key using the remaining GHZ states after authentication. This secret key does not leak even to the arbitrator by the properties of the entanglement. We will show that our protocol is secure against the cloning attack.

  8. Quantum hacking on a practical continuous-variable quantum cryptosystem by inserting an external light (United States)

    Qin, Hao; Kumar, Rupesh; Alleaume, Romain


    We report here a new side channel attack on a practical continuous-variable (CV) quantum key distribution (QKD) system. Inspired by blinding attack in discrete-variable QKD, we formalize an attack strategy by inserting an external light into a CV QKD system implemented Gaussian-modulated coherent state protocol and show that our attack can compromise its practical security. In this attack, we concern imperfections of a balanced homodyne detector used in CV QKD. According to our analysis, if one inserts an external light into Bob's signal port, due to the imperfect subtraction from the homodyne detector, the leakage of the external light contributes a displacement on the homodyne signal which causes detector electronics saturation. In consequence, Bob's quadrature measurement is not linear with the quadrature sent by Alice. By considering such vulnerability, a potential Eve can launch a full intercept-resend attack meanwhile she inserts an external light into Bob's signal port. By selecting proper properties of the external light, Eve actively controls the induced displacement value from the inserted light which results saturation of homodyne detection. In consequence, Eve can bias the excess noise due to the intercept-resend attack and the external light, such that Alice and Bob believe their excess noise estimation is below the null key threshold and they can still share a secret key. Our attack shows that the detector loopholes also exist in CV QKD, and it seems influence all the CV QKD systems using homodyne detection, since all the practical detectors have finite detection range.

    We study the capacity of a superdense coding protocol in the case of a noisy channel. We consider the case where the channel acts on Alice's side, and the one where it acts both on Alice's and Bob's side. In the latter case, the noise can be correlated or uncorrelated. We study various noise models and various bipartite input states, and derive the optimal capacity.
