    Primary particles of cosmic radiation with highest energies cannot in view of their low intensity be recorded directly but for this purpose the phenomenon is used that these particles interact with nuclei in the atmosphere and give rise to what are known as extensive air showers. It was found that 40% of primary particles with an energy of 10 15 to 10 16 eV consist of protons, 12 to 15% of helium nuclei, 15% of iron nuclei, the rest of nuclei of other elements. Radiation intensity with an energy of 10 18 to 10 19 eV depends on the direction of incoming particles. Maximum intensity is in the direction of the centre of the nearest clustre of galaxies, minimal in the direction of the central area of our galaxy. (Ha)

  3. The highest energies in the Universe

    There are not many issues of fundamental importance which have induced so many problems for astrophysicists like the question of the origin of cosmic rays. This radiation from the outer space has an energy density comparable with that of the visible starlight or of the microwave background radiation. It is an important feature of our environment with many interesting aspects. A most conspicuous feature is that the energy spectrum of cosmic rays seems to have no natural end, though resonant photopion production with the cosmic microwave background predicts a suppression of extragalactic protons above the so-called Greisen-Zatsepin-Kuz’min cutoff at about EGZK = 5 × 10"1"9 eV. In fact the highest particle energies ever observed on the Earth, stem from observations of Ultrahigh Energy Cosmic Rays (E > 3 × 10"1"9 eV). But the present observations by the AGASA and HiRes Collaborations, partly a matter of debate, are origin of a number of puzzling questions, where these particles are coming from, by which gigantic acceleration mechanism they could gain such tremendous energies and how they have been able to propagate to our Earth. These questions imply serious problems of the understanding of our Universe. There are several approaches to clarify the mysteries of the highest energies and to base the observations on larger statistical accuracy. The Pierre Auger Observatory, being in installation in the Pampa Amarilla in the Province Mendoza in Argentina, is a hybrid detector, combining a large array of water Cerenkov detectors (registering charged particles generated in giant extended air showers) with measurements of the fluorescence light produced during the air shower development. This contribution will illustrate the astrophysical motivation and the current status of the experimental efforts, and sketch the ideas about the origin of these particles.

    Introducing a simple Galactic wind model patterned after the solar wind we show that back-tracing the orbits of the highest energy cosmic events suggests that they may all come from the Virgo cluster, and so probably from the active radio galaxy M87. This confirms a long standing expectation. Those powerful radio galaxies that have their relativistic jets stuck in the interstellar medium of the host galaxy, such as 3C147, will then enable us to derive limits on the production of any new kind of particle, expected in some extensions of the standard model in particle physics. New data from HIRES will be crucial in testing the model proposed here.

  5. Directional clustering in highest energy cosmic rays

    2001-01-01

    An unexpected degree of small-scale clustering is observed in highest-energy cosmic ray events. Some directional clustering can be expected due to purely statistical fluctuations for sources distributed randomly in the sky. This creates a background for events originating in clustered sources. We derive analytic formulas to estimate the probability of random cluster configurations, and use these formulas to study the strong potential of the HiRes, Auger, Telescope Array and EUSO-OWL-AirWatch facilities for deciding whether any observed clustering is most likely due to nonrandom sources. For a detailed comparison to data, our analytical approach cannot compete with Monte Carlo simulations, including experimental systematics. However, our derived formulas do offer two advantages: (i) easy assessment of the significance of any observed clustering, and most importantly, (ii) an explicit dependence of cluster probabilities on the chosen angular bin size

    In these lectures I introduce and discuss aspects of currently active fields of interest related to the production, transport and detection of high energy particles from extraterrestrial sources. I have payed most attention to the highest energies and I have divided the material according to the types of particles which will be searched for with different experimental facilities in planning: hadrons, gamma rays and neutrinos. Particular attention is given to shower development, stochastic acceleration and detection techniques

  7. Z-burst scenario for the highest energy cosmic rays

    2002-10-01

    The origin of highest energy cosmic rays is yet unknown. An appealing possibility is the so-called Z-burst scenario, in which a large fraction of these cosmic rays are decay products of Z bosons produced in the scattering of ultrahigh energy neutrinos on cosmological relic neutrinos. The comparison between the observed and predicted spectra constrains the mass of the heaviest neutrino. The required neutrino mass is fairly robust against variations of the presently unknown quantities, such as the amount of relic neutrino clustering, the universal photon radio background and the extragalactic magnetic field. Considering different possibilities for the ordinary cosmic rays the required neutrino masses are determined. In the most plausible case that the ordinary cosmic rays are of extragalactic origin and the universal radio background is strong enough to suppress high energy photons, the required neutrino mass is 0.08 eV ≤ m ν ≤ 0.40 eV. The required ultrahigh energy neutrino flux should be detected in the near future by experiments such as AMANDA, RICE or the Pierre Auger Observatory. (orig.)

    EGRET has extended the highest energy observations of gamma-ray bursts to GeV gamma rays. Such high energies imply the fireball that is radiating the gamma-rays has a bulk Lorentz factor of several hundred. However, EGRET only detected a few gamma-ray bursts. GLAST will likely detect several hundred bursts and may extend the maximum energy to a few 100 GeV. Meanwhile new ground based detectors with sensitivity to gamma-ray bursts are beginning operation, and one recently reported evidence for TeV emission from a burst

  14. Development of an Interferometric Phased Array Trigger for Balloon-Borne Detection of the Highest Energy Cosmic Particles

    Science.gov (United States)

    Vieregg, Abigail

    Through high energy neutrino astrophysics, we explore the structure and evolution of the universe in a unique way and learn about the physics inside of astrophysical sources that drives the acceleration of the highest energy particles. Neutrinos travel virtually unimpeded through the universe, making them unique messenger particles for cosmic sources and carrying information about very distant sources that would otherwise be unavailable. The highest energy neutrinos (E>10^{18} eV), created as a by-product of the interaction of the highest energy cosmic rays with the cosmic microwave background, are an important tool for determining the origin of the highest energy cosmic rays and still await discovery. Balloon-borne and ground-based experiments are poised to discover these ultra-high energy (UHE) cosmogenic neutrinos by looking for radio emission from two different types of neutrino interactions: particle cascades induced by neutrinos in glacial ice, and extensive air showers in the atmosphere induced by the charged-particle by-product of tau neutrinos interacting in the earth. These impulsive radio detectors are also sensitive to radio emission from extensive air showers induced directly by UHE cosmic rays. Balloon-borne experiments are especially well-suited for discovering the highest energy neutrinos, and are the only way to probe the high energy cutoff of the sources themselves to reveal the astrophysics that drives the central engines inside the most energetic accelerators in the universe. Balloon platforms offer the chance to monitor extremely large volumes of ice and atmosphere, but with a higher energy threshold compared to ground-based observatories, since the neutrino interaction happens farther from the detector. This tradeoff means that the sensitivity of balloon-borne experiments, such as the Antarctic Impulsive Transient Antenna (ANITA) or the ExaVolt Antenna, is optimized for discovery of the highest energy neutrinos. We are developing an

  16. Where do the highest energy CR's come from? and How does the Milky Way affect their arrival directions?

    Directory of Open Access Journals (Sweden)

    Kronberg Philipp

    2013-06-01

    Full Text Available A “grand magnetic design” for the Milky Way disk clearly emerges within ~1.5 kpc of the Galactic mid-plane near the Sun [1], and reveals a pitch angle of −5.5°. directed inward from the Solar tangential. This pitch angle can be expected to differ for Galactic disc locations other than ours. Above ~1.5 kpc, the field geometry is completely different, and its 3-D structure is not yet completely specified. However it appears that the UHECR (> 5 · 1019 eV propagation to us is not much affected by the halo field, at least for protons. I discuss new multi-parameter analyses of UHECR deflections which provide a conceptual “template” for future interpretations of energy-species-direction data from AUGER, HiRes etc., and their successors [2]. I show how the strength and structure of the cosmologically nearby intergalactic magnetic field, BIGM, is now well-estimated out to D ~5 Mpc from the Milky Way: − 20nG. These are the first VHECR data-based estimates of BIGM on nearby supragalactic scales, and are also important for understanding and modeling CR propagation in the more distant Universe. CR Acceleration to the highest energies is probably a natural accompanying phenomenon of Supermassive Black Hole (SMBH-associated jets and lobes [3]. I briefly describe what we know about magnetic configurations in these candidate sites for UHECR acceleration, and the first direct estimate of an extragalactic Poynting flux current, ~3 · 1018 Amperes [4, 5]. This number connects directly to SMBH accretion disk physics, and leads directly to ideas of how VHECR acceleration in jets and lobes, possibly involving magnetic reconnection, is likely to be common in the Universe. It remains to be fully understood.

    1982-01-01

    The avalanche production of magnetic monopoles is possible in neutron stars. Big part of the magnetic field energy can be used to accelerate a pulse of 10 30 monopoles to the energy E > approximately 10 17 eV. Thus the neutron stars may be ''point'' sources of bursts of highest energy Cosmic Rays. The emission of brehmsstrahlung photons by these highly relativistic monopoles would be seen as X and gamma bursts. This ''exotic'' model for March 5th, 1979 event, predicts that it has been followed by burst of highest energy Cosmic Rays coming from the direction of LMC supernovae remanent N49

    2016-10-19

    Meiosis is a key event of sexual life cycles in eukaryotes. Its mechanistic details have been uncovered in several model organisms, and most of its essential features have received various and often contradictory evolutionary interpretations. In this perspective, we present an overview of these often 'weird' features. We discuss the origin of meiosis (origin of ploidy reduction and recombination, two-step meiosis), its secondary modifications (in polyploids or asexuals, inverted meiosis), its importance in punctuating life cycles (meiotic arrests, epigenetic resetting, meiotic asymmetry, meiotic fairness) and features associated with recombination (disjunction constraints, heterochiasmy, crossover interference and hotspots). We present the various evolutionary scenarios and selective pressures that have been proposed to account for these features, and we highlight that their evolutionary significance often remains largely mysterious. Resolving these mysteries will likely provide decisive steps towards understanding why sex and recombination are found in the majority of eukaryotes.This article is part of the themed issue 'Weird sex: the underappreciated diversity of sexual reproduction'. © 2016 The Author(s).

    One of the mysteries puzzling human mind since the origin of mankind is the concept of "reincarnation" which literally means "to take on the flesh again." As the civilizations evolved, beliefs got discriminated and disseminated into various religions. The major division manifested was "East" and "West." The eastern religions being more philosophical and less analytical, have accepted reincarnation. However, the different eastern religions like Hinduism, Jainism, and Buddhism have differed in their faith on rebirth. Further, the Islam as well as the most dominant religion of the world, Christianity, having its origin in the west, have largely denied reincarnation, though some sub-sects still show interest in it. Also many mystic and esoteric schools like theosophical society have their unique description on rebirth. This article describes reincarnation as perceived by various religions and new religious movements as well as some research evidence.

    1997-01-01

    It has long been one of the most fundamental problems of philosophy, and it is now, John Searle writes, "the most important problem in the biological sciences": What is consciousness? Is my inner awareness of myself something separate from my body? In what began as a series of essays in The New York Review of Books, John Searle evaluates the positions on consciousness of such well-known scientists and philosophers as Francis Crick, Gerald Edelman, Roger Penrose, Daniel Dennett, David Chalmers, and Israel Rosenfield. He challenges claims that the mind works like a computer, and that brain functions can be reproduced by computer programs. With a sharp eye for confusion and contradiction, he points out which avenues of current research are most likely to come up with a biological examination of how conscious states are caused by the brain. Only when we understand how the brain works will we solve the mystery of consciousness, and only then will we begin to understand issues ranging from artificial intelligence...

  5. The mystery of Morgellons disease: infection or delusion?

    Savely, Virginia R; Leitao, Mary M; Stricker, Raphael B

    2006-01-01

    Morgellons disease is a mysterious skin disorder that was first described more than 300 years ago. The disease is characterized by fiber-like strands extruding from the skin in conjunction with various dermatologic and neuropsychiatric symptoms. In this respect, Morgellons disease resembles and may be confused with delusional parasitosis. The association with Lyme disease and the apparent response to antibacterial therapy suggest that Morgellons disease may be linked to an undefined infectious process. Further clinical and molecular research is needed to unlock the mystery of Morgellons disease.

After discussing the mystifications a new formulation of the problem is proposed. Then we turn to the mysteries. An answer to the recurring question 'Just what are we accomplishing when we maximize entropy?' [8], based on MaxProb rationale of MaxEnt [6], is recalled. A brief view on the other mystery: 'What is the relation between MaxEnt and the Bayesian method?' [9], in light of the MaxProb rationale of MaxEnt suggests that there is not and cannot be a conflict between MaxEnt and Bayes Theorem.

  10. Groundwater: from mystery to management

    International Nuclear Information System (INIS)

    Narasimhan, T N

    2009-01-01

    Groundwater has been used for domestic and irrigation needs from time immemorial. Yet its nature and occurrence have always possessed a certain mystery because water below the land surface is invisible and relatively inaccessible. The influence of this mystery lingers in some tenets that govern groundwater law. With the birth of modern geology during the late nineteenth century, groundwater science became recognized in its own right. Over the past two centuries, groundwater has lost its shroud of mystery, and its scientific understanding has gradually grown hand-in-hand with its development for human use. Groundwater is a component of the hydrological cycle, vital for human sustenance. Its annual renewability from precipitation is limited, and its chemical quality is vulnerable to degradation by human action. In many parts of the world, groundwater extraction is known to greatly exceed its renewability. Consequently, its rational management to benefit present and future generations is a matter of deep concern for many nations. Groundwater management is a challenging venture, requiring an integration of scientific knowledge with communal will to adapt to constraints of a finite common resource. As scientists and policy makers grapple with the tasks of groundwater management, it is instructive to reflect on the evolution of groundwater knowledge from its initial phase of demystification at the beginning of the nineteenth century, through successive phases of technological conquest, scientific integration, discovery of unintended consequences and the present recognition of an imperative for judicious management. The following retrospective provides a broad context for unifying the technical contributions that make up this focus issue on groundwater resources, climate and vulnerability.

  11. Challenges for highest energy circular colliders

    2014-01-01

    A new tunnel of 80–100 km circumference could host a 100 TeV centre-of-mass energy-frontier proton collider (FCC-hh/VHE-LHC), with a circular lepton collider (FCCee/TLEP) as potential intermediate step, and a leptonhadron collider (FCC-he) as additional option. FCC-ee, operating at four different energies for precision physics of the Z, W, and Higgs boson and the top quark, represents a significant push in terms of technology and design parameters. Pertinent R&D efforts include the RF system, topup injection scheme, optics design for arcs and final focus, effects of beamstrahlung, beam polarization, energy calibration, and power consumption. FCC-hh faces other challenges, such as high-field magnet design, machine protection and effective handling of large synchrotron radiation power in a superconducting machine. All these issues are being addressed by a global FCC collaboration. A parallel design study in China prepares for a similar, but smaller collider, called CepC/SppC.

  14. The mystery of language evolution

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available Understanding the evolution of language requires evidence regarding origins and processes that led to change. In the last 40 years, there has been an explosion of research on this problem as well as a sense that considerable progress has been made. We argue instead that the richness of ideas is accompanied by a poverty of evidence, with essentially no explanation of how and why our linguistic computations and representations evolved. We show that, to date, 1 studies of nonhuman animals provide virtually no relevant parallels to human linguistic communication, and none to the underlying biological capacity; 2 the fossil and archaeological evidence does not inform our understanding of the computations and representations of our earliest ancestors, leaving details of origins and selective pressure unresolved; 3 our understanding of the genetics of language is so impoverished that there is little hope of connecting genes to linguistic processes any time soon; 4 all modeling attempts have made unfounded assumptions, and have provided no empirical tests, thus leaving any insights into language’s origins unverifiable. Based on the current state of evidence, we submit that the most fundamental questions about the origins and evolution of our linguistic capacity remain as mysterious as ever, with considerable uncertainty about the discovery of either relevant or conclusive evidence that can adjudicate among the many open hypotheses. We conclude by presenting some suggestions about possible paths forward.

  5. Distance Measurement Solves Astrophysical Mysteries

    Science.gov (United States)

    2003-08-01

    Location, location, and location. The old real-estate adage about what's really important proved applicable to astrophysics as astronomers used the sharp radio "vision" of the National Science Foundation's Very Long Baseline Array (VLBA) to pinpoint the distance to a pulsar. Their accurate distance measurement then resolved a dispute over the pulsar's birthplace, allowed the astronomers to determine the size of its neutron star and possibly solve a mystery about cosmic rays. "Getting an accurate distance to this pulsar gave us a real bonanza," said Walter Brisken, of the National Radio Astronomy Observatory (NRAO) in Socorro, NM. Monogem Ring The Monogem Ring, in X-Ray Image by ROSAT satellite CREDIT: Max-Planck Institute, American Astronomical Society (Click on Image for Larger Version) The pulsar, called PSR B0656+14, is in the constellation Gemini, and appears to be near the center of a circular supernova remnant that straddles Gemini and its neighboring constellation, Monoceros, and is thus called the Monogem Ring. Since pulsars are superdense, spinning neutron stars left over when a massive star explodes as a supernova, it was logical to assume that the Monogem Ring, the shell of debris from a supernova explosion, was the remnant of the blast that created the pulsar. However, astronomers using indirect methods of determining the distance to the pulsar had concluded that it was nearly 2500 light-years from Earth. On the other hand, the supernova remnant was determined to be only about 1000 light-years from Earth. It seemed unlikely that the two were related, but instead appeared nearby in the sky purely by a chance juxtaposition. Brisken and his colleagues used the VLBA to make precise measurements of the sky position of PSR B0656+14 from 2000 to 2002. They were able to detect the slight offset in the object's apparent position when viewed from opposite sides of Earth's orbit around the Sun. This effect, called parallax, provides a direct measurement of

  6. Population cycles: generalities, exceptions and remaining mysteries

    Science.gov (United States)

    2018-01-01

    Population cycles are one of nature's great mysteries. For almost a hundred years, innumerable studies have probed the causes of cyclic dynamics in snowshoe hares, voles and lemmings, forest Lepidoptera and grouse. Even though cyclic species have very different life histories, similarities in mechanisms related to their dynamics are apparent. In addition to high reproductive rates and density-related mortality from predators, pathogens or parasitoids, other characteristics include transgenerational reduced reproduction and dispersal with increasing-peak densities, and genetic similarity among populations. Experiments to stop cyclic dynamics and comparisons of cyclic and noncyclic populations provide some understanding but both reproduction and mortality must be considered. What determines variation in amplitude and periodicity of population outbreaks remains a mystery. PMID:29563267

It is therefore better to see how he identifies the mystery than to focus on his answers, because he too recognizes his limits. His intellectual prowess can be seen more clearly when he “names the mystery” than by thinking that he has solved it.

    Full Text Available The mystery fiction is a popular pleasure reading genre in Taiwan. This article describes a grounded theory study that explored the reading pleasures and selection behavior of mystery fans. Based on the in-depth interview with 21 engaged mystery readers, this study identified seven types of reading pleasures, i.e., a sense of achievement from puzzle solving, feelings of amazement from the revelation of truths, satisfaction of curiosity for the unknown, a sense of compensation from seeing justice, senses of empathy and sympathy from identifying with the story characters, and the reflection of the social issues and values raised in the stories. The charms of mystery fiction may be systematically described by following four of Hudson’s (1910 conceptualization of fiction elements: i.e. the plot, characters, time and place, and the author’s view of life prevailed in the stories. In regards to readers’ selection behavior, this study identified four selection approaches commonly used by the experienced readers to discover works that possibly meet their expectations, i.e., the subgenre-oriented, author-oriented, series-oriented, and story-oriented approaches. In addition, six factors may influence readers’ selection of works, i.e., availability of expert comments, trust and confidence in the publishers, book award information, adaptation into movies or television, quality of translation, and first impression of the physical books.

    Quinn, Helen R

    2008-01-01

    In the first fractions of a second after the Big Bang lingers a question at the heart of our very existence: why does the universe contain matter but almost no antimatter? The laws of physics tell us that equal amounts of matter and antimatter were produced in the early universe--but then, something odd happened. Matter won out over antimatter; had it not, the universe today would be dark and barren. But how and when did this occur? Helen Quinn and Yossi Nir guide readers into the very heart of this mystery--and along the way offer an exhilarating grand tour of cutting-edge physics. They explain both the history of antimatter and recent advances in particle physics and cosmology. And they discuss the enormous, high-precision experiments that particle physicists are undertaking to test the laws of physics at their most fundamental levels--and how their results reveal tantalizing new possibilities for solving this puzzle at the heart of the cosmos. The Mystery of the Missing Antimatter is at once a history of i...

  16. Quantum physics and the beam splitter mystery

    2015-09-01

    Optical lossless beam splitters are frequently encountered in fundamental physics experiments regarding the nature of light, including "which-way" determination or the EPR paradox and their measurement apparatus. Although they look as common optical components at first glance, their behaviour remains somewhat mysterious since they apparently exhibit stand-alone particle-like features, and then wave-like characteristics when inserted into a Mach-Zehnder interferometer. In this communication are examined and discussed some basic properties of these beamssplitters, both from a classical optics and quantum physics point of view. Herein the most evident convergences and contradictions are highlighted, and the results of a few emblematic experiments demonstrating photon existence are discussed. Alternative empirical models are also proposed in order to shed light on some remaining issues.

  17. Searching for Judy: How small mysteries affect narrative processes and memory

    Science.gov (United States)

    Love, Jessica; McKoon, Gail; Gerrig, Richard J.

    2010-01-01

    Current theories of text processing say little about how author’s narrative choices, including the introduction of small mysteries, can affect readers’ narrative experiences. Gerrig, Love, and McKoon (2009) provided evidence that one type of small mystery—a character introduced without information linking him or her to the story—affects readers’ moment-by-moment processing. For that project, participants read stories that introduced characters by proper name alone (e.g., Judy) or with information connecting the character to the rest of the story (e.g., our principal Judy). In an on-line recognition probe task, responses to the character’s name three lines after his or her introduction were faster when the character had not been introduced with connecting information, suggesting that the character remained accessible awaiting resolution. In the four experiments in this paper, we extended our theoretical analysis of small mysteries. In Experiments 1 and 2, we found evidence that trait information (e.g., daredevil Judy) is not sufficient to connect a character to a text. In Experiments 3 and 4, we provide evidence that the moment-by-moment processing effects of such small mysteries also affect readers’ memory for the stories. We interpret the results in terms of Kintsch’s Construction-Integration model (1988) of discourse processing. PMID:20438273

    Ferre, P. A.

    2011-12-01

    In an article in the New Yorker in 2007, Malcolm Gladwell discussed the distinction that national security expert Gregory Treverton has made between puzzles and mysteries. Specifically, puzzles are problems that we understand and that will eventually be solved when we amass enough information. (Think crossword puzzles.) Mysteries are problems for which we have the necessary information, but it is often overwhelmed by irrelevant or misleading input. To solve a mystery, we require improved analysis. (Think find-a-word.) Gladwell goes on to explain that, in the national security realm, the Cold War was a puzzle while the current national security condition is a mystery. I will discuss the past, current, and future trajectories of hydrogeophysics in terms of puzzles and mysteries. I will also add a third class of problem: conundrums - those for which we lack sufficient information about their structure to know how to solve them. A conundrum is a mystery with an unexpected twist. I hope to make the case that the future growth of hydrogeophysics lies in our ability to address this more challenging and more interesting class of problem.

  20. The Mysteries of the Quantum World

    CERN Multimedia

    2005-01-01

    As part of the World Year of Physics, the Physics Section of the University of Geneva is organising a series of lectures for the uninitiated. Each of the lectures will begin with a demonstration in the auditorium of the detection of cosmic rays and, in collaboration with Professor E. Ellberger of the Conservatoire de Musique de Genève, of how these signals from the farthest reaches of the Universe can be used to create 'cosmic music'. The sixth lecture, entitled 'Einstein's objections to the quantum computer', tackles a mysterious subject, one which Einstein had numerous doubts about. The lecture will be given by Professor Alain Aspect of the Orsay Institute for Optics. In 1935 Einstein discovered a mind-boggling property of quantum mechanics: entanglement, which conflicted with his realist and localised vision of the world. This led him into a heated debate with Niels Bohr. We now know that entangled 'twin photons', even when separated by distances of dozens of kilometres, have this extraordinary proper...

    .Bassa and collaborators also found that the properties of the host galaxy are consistent with those of a type of galaxy known as extreme emission line galaxies. This provides a tantalizing clue, as these galaxies are known to host both hydrogen-poor superluminous supernovae and long-duration gamma-ray bursts.Linking to the CauseWhat can this tell us about the cause of FRB 121102? The fact that this burst repeats already eliminates cataclysmic events as the origin. But the projected location of FRB 121102 within a star-forming region especially in a host galaxy thats similar to those typically hosting superluminous supernovae and long gamma-ray bursts strongly suggests theres a relation between these events.Artists impression of a gamma-ray burst in a star-forming region. [NASA/Swift/Mary Pat Hrybyk-Keith and John Jones]The authors propose that this observed coincidence, supported by models of magnetized neutron star birth, indicate an evolutionary link between fast radio bursts and neutron stars. In this picture, neutron stars or magnetars are born as long gamma-ray bursts or hydrogen-poor supernovae, and then evolve into fast-radio-burst-emitting sources.This picture may finally explain the cause of fast radio bursts but Bassa and collaborators caution that its also possible that this model applies only to FRB 121102. Since FRB 121102 is unique in being the only burst discovered to repeat, its cause may also be unique. The authors suggest that targeted searches of star-forming regions in galaxies similar to FRB 121102s host may reveal other repeating burst candidates, helping us to unravel the ongoing mystery of fast radio bursts.CitationC.

    2008-01-01

    Astronomers have produced a scientific gold mine of detailed, high-quality images of nearby galaxies that is yielding important new insights into many aspects of galaxies, including their complex structures, how they form stars, the motions of gas in the galaxies, the relationship of "normal" matter to unseen "dark matter," and many others. An international team of scientists used more than 500 hours of observations with the National Science Foundation's Very Large Array (VLA) radio telescope to produce detailed sets of images of 34 galaxies at distances from 6 to 50 million light-years from Earth. Their project, called The HI Nearby Galaxy Survey, or THINGS, required two years to produce nearly one TeraByte of data. HI ("H-one") is an astronomical term for atomic hydrogen gas. The astronomers presented their initial findings to the American Astronomical Society's (AAS) meeting in Austin, Texas. "Studying the radio waves emitted by atomic hydrogen gas in galaxies is an extremely powerful way to learn what's going on in nearby galaxies. The THINGS survey uses that tool to provide sets of images of the highest quality and sensitivity for a substantial sample of galaxies of different types," said Fabian Walter, of the Max-Planck Institute for Astronomy in Heidelberg, Germany.

This combination provides an unprecedented resource for unravelling the mystery of how a galaxy's gaseous material influences its overall evolution. Analysis of THINGS data already has yielded numerous scientific payoffs. For example, one study has shed new light on astronomers' understanding of the gas-density threshold required to

  12. Ordinary Dark Matter versus Mysterious Dark Matter in Galactic Rotation

    Science.gov (United States)

    Gallo, C. F.; Feng, James

    2008-04-01

    To theoretically describe the measured rotational velocity curves of spiral galaxies, there are two different approaches and conclusions. (1) ORDINARY DARK MATTER. We assume Newtonian gravity/dynamics and successfully find (via computer) mass distributions in bulge/disk configurations that duplicate the measured rotational velocities. There is ordinary dark matter within the galactic disk towards the cooler periphery which has lower emissivity/opacity. There are no mysteries in this scenario based on verified physics. (2) MYSTERIOUS DARK MATTER. Others INaccurately assume the galactic mass distributions follow the measured light distributions, and then the measured rotational velocity curves are NOT duplicated. To alleviate this discrepancy, speculations are invoked re ``Massive Peripheral Spherical Halos of Mysterious Dark Matter.'' But NO matter has been detected in this UNtenable Halo configuration. Many UNverified ``Mysteries'' are invoked as necessary and convenient. CONCLUSION. The first approach utilizing Newtonian gravity/dynamics and searching for the ordinary mass distributions within the galactic disk simulates reality and agrees with data.

  20. Community in Panic: Perceptions, impacts and lessons at risk communication on Pangasinan Mysterious Disease

    Directory of Open Access Journals (Sweden)

    Adrian Lawrence Carvajal

    2015-02-01

    Full Text Available Communicating information about possible life threatening concerns can be very delicately difficult, and if it is not done well, the communicator can put the affected public at greater risk by creating misunderstanding or possibly inciting unwarranted panic. On February 24, 2014, a late night news program reported that a “mysterious flesh-eating illness is slowly” spreading in Pangasinan, a province in the Philippines with a population of more than three million.The news report connected two case studies from the towns of Villasis and Santa Barbara, Pangasinan to a prophecy by a self-titled prophet who forewarns of a flesh-eating disease in the said province. Just hours after the report came out that night, the hashtag #PrayForPangasinan trended on Twitter, and link of the video have been boundlessly shared on Facebook and other online social media. Anchored on the mental noise and risk perception theories, the study delves into the perceptions of risk of the affected public and determines the risk communication impacts and lessons of the Pangasinan Mysterious Disease. The findings of the study on the perceptions of risk by the affected public, the risk communication impacts and lessons on the news report is significant as the fundamental goal of risk communication is to provide meaningful, relevant and accurate information, in clear and understandable terms targeted to the concerned and affected publicand spur all concerned to a higher degree of consensus and support for a beneficial action.

  1. Climate change projections: past and future mysteries of climate science

    International Nuclear Information System (INIS)

    Meehl, Gerald A.

    2007-01-01

    Full text: Full text: The history of climate change has been wrapped in mysteries. Some have been solved, and we await the outcome of others. The major mystery of 20th century climate was why did temperatures rise in the early part of the century, level off, and then rise rapidly again after the 1970s? It has only been in the past seven years that advances in climate modelling have allowed us to deconstruct 20th century climate to pull apart the separate influences of natural and human-caused factors. This has allowed us to understand the subtle interplay between these various influences that produced the temperature time evolution. Another mystery has involved extreme weather and climate events. Again, climate models have allowed us to quantify how the small changes in average climate translate into much larger changes of regional extremes. The biggest remaining mysteries in climate science involve the future, and how the climate will evolve over the coming century. Up until now, various scenarios postulating different possible outcomes for 21st century climate, assuming different types of human activities, have been run in the climate models to provide a wide range of possible futures. However, more recently the outlook for global warming is being framed as a combination of mitigation and adaptation. If policy actions are taken to mitigate part of the problem of global warming, then climate models must be relied on to quantify the time-evolving picture of how much regional climate change we must adapt to. Solving this mystery will be the biggest and most important challenge ever taken on by the climate modelling community

    Brau, James E [University of Oregon

    2010-11-23

    The universe is dark and mysterious, more so than even Einstein imagined. While modern science has established deep understanding of ordinary matter, unidentified elements ("Dark Matter" and "Dark Energy") dominate the structure of the universe, its behavior and its destiny. What are these curious elements? We are now working on answers to these and other challenging questions posed by the universe with experiments at particle accelerators on Earth. Results of this research may revolutionize our view of nature as dramatically as the advances of Einstein and other quantum pioneers one hundred years ago. Professor Brau will explain for the general audience the mysteries, introduce facilities which explore them experimentally and discuss our current understanding of the underlying science. The presentation is at an introductory level, appropriate for anyone interested in physics and astronomy.

    Johnston, Daniel; Narayanan, Rishikesh

    2008-06-01

    Santiago Ramón y Cajal had referred to neurons as the 'mysterious butterflies of the soul.' Wings of these butterflies--their dendrites--were traditionally considered as passive integrators of synaptic information. Owing to a growing body of experimental evidence, it is now widely accepted that these wings are colorful, endowed with a plethora of active conductances, with each family of these butterflies made of distinct hues and shades. Furthermore, rapidly evolving recent literature also provides direct and indirect demonstrations for activity-dependent plasticity of these active conductances, pointing toward chameleonic adaptability in these hues. These experimental findings firmly establish the immense computational power of a single neuron, and thus constitute a turning point toward the understanding of various aspects of neuronal information processing. In this brief historical perspective, we track important milestones in the chameleonic transmogrification of these mysterious butterflies.

  8. A Brief Introduction on Mystery, the Unknown, Surprise

    2012-03-01

    Full Text Available In this age of globalization, this age of so many ways to know—and so many ways to know things so quickly—it is both satisfying and deeply unnerving to come upon things and events that are really hard to understand, things and events so shocking or strange or mysterious, that they seem Unknown. Perhaps even unknowable. The first note of NANO Issue 2 focuses on an unsolved murder and reveals a mystery that is confounding, creepy, and yet oddly compelling. In “Karr’s Kill Cult: Virtual Cults and Pseudo-Killing in the Digital Age,” Jeremy Biles and Brian Collins explore the edges of where cyber-crime threatens to turn real—and vice versa. In the second note, Jennifer Ballengee compares Oedipus at Colonus with Don DeLillo’s Falling Man.

    The mystery of the gun turret in the desert began with an ingenious idea: to develop a reusable open-air line of sight diagnostic device to support LLNL’s early nuclear weapons development efforts. Obtained from the Mare Island Navy Shipyard (MINS) in January 1957, the gun turret traveled by ship to the Naval Construction Battalion base at Port Hueneme, California, and then by truck to Area 2 in the Yucca Flats valley at the Nevada Nuclear Security Site (NNSS).

  11. Reconstitutions of the evangelical text in the Mysteries of the Orthodox Church

    Directory of Open Access Journals (Sweden)

    Tuca Nicusor

    2015-11-01

    Full Text Available The miracles performed by Jesus Christ are primary forms of practice of the Holy Mysteries. Therefore, every one of the seven Holy Mysteries finds its correspondent in the healings performed by our Savior: for the Mystery of Baptism, we have highlighted as paradigms the healing of the man born blind, but also the resurrections from the dead; for the Chrismation Mystery, the paradigms are the healing of the woman who had been suffering from a hemorrhage for 12 years and the healing of the deaf man who could hardly speak, while for the Mystery of Confession we have highlighted as defining examples the public confession of the father of the lunatic child, the blind men of Jericho and Bethsaida and the leper of Galilee. The Mystery of the Holy Eucharist has as special paradigms the parable of the emperor’s son’s wedding and the parable of the people invited to supper, while the Mystery of Priesthood (or Ordination is prefigured by the second wonderful fishing and the first multiplication of the loaves of bread. As far as the Mystery of Marriage is concerned, beside the miracle of Cana in Galilee, suggestive is also the “salvation of Zacchaeus’ house”, while the healings of the devil-possessed are eloquent for the illustration of the Mystery of the Holy Unction.

    The Chinese mystery snail (Bellamya chinensis) is a non-indigenous, invasive species in freshwater ecosystems of North America. We provide fecundity estimates for a population of these snails in a Nebraska reservoir. We dissected 70 snails, of which 29 were females. Nearly all female snails contained developing young, with an average of 25 young per female. Annual fecundity was estimated at between 27.2 and 33.3 young per female per year. Based on an estimated adult population and the calculated fecundity, the annual production for this reservoir was between 2.2 and 3.7 million young.

    Science.gov (United States)

    Atmospheric electricity research has come a long way since Benjamin Franklin's kite-flying days. But what researchers have been learning lately about above-thunderstorm electricity has wrought a whole new era of mysteries.For a start, last summer a Colorado meteorologist sparked interest in a terrestrial phenomenon that the community first observed more than 100 years ago: optical flashes that occur above thunderstorms—at least 30 km above Earth. Walter Lyons with the Ft. Collins-based Mission Research Corporation, demonstrated that such flashes are not anomalies, as conventional scientific wisdom had held. He filmed hundreds of flashes during a 2-week period.

    Slow Light is a popular treatment of today's astonishing breakthroughs in the science of light. Even though we don't understand light's quantum mysteries, we can slow it to a stop and speed it up beyond its Einsteinian speed limit, 186,000 miles/sec; use it for quantum telecommunications; teleport it; manipulate it to create invisibility; and perhaps generate hydrogen fusion power with it. All this is lucidly presented for non-scientists who wonder about teleportation, Harry Potter invisibility cloaks, and other fantastic outcomes. Slow Light shows how the real science and the fantasy inspire

    2007-12-01

    Water is perhaps the most ubiquitous, and the most essential, of any molecule on earth. Indeed, it defies the imagination of even the most creative science fiction writer to picture what life would be like without water. Despite decades of research, however, water's puzzling properties are not understood and 63 anomalies that distinguish water from other liquids remain unsolved. We introduce some of these unsolved mysteries, and demonstrate recent progress in solving them. We present evidence from experiments and computer simulations supporting the hypothesis that water displays a special transition point (which is not unlike the “tipping point” immortalized by Malcolm Gladwell). The general idea is that when the liquid is near this “tipping point,” it suddenly separates into two distinct liquid phases. This concept of a new critical point is finding application to other liquids as well as water, such as silicon and silica. We also discuss related puzzles, such as the mysterious behavior of water near a protein.

    Genetics professor Michelle Murphy loses her husband under mysterious circumstances and without warning, while their brilliant eight year old daughter Avalon, adopted in Kazakhstan, stubbornly believes she is a mutant. As if this were not enough she soon finds herself thrown into the middle of a quickly thickening plot, where the legacy of Genghis Khan meets the hunt for FOXP5, a genetic transcription factor that could herald the dawn of new human species. Initially caught helplessly between well-meaning fellow scientists, the government and more sinister agents, Michelle, with the help of a host of unlikely heroes, eventually takes control and finds the courage to confront the decision of whether to save human lives or humanity. The scientific and technical aspects underlying the plot - in particular aspects of FOX proteins, genetic mutations, viruses and cancer as well as the relation between intelligence and cortical complexity - are introduced and discussed by the authors in an extensive non-technical a...

    2007-01-01

    Full Text Available Fetus in Fetu (FIF is a rare condition where a monozygotic diamnionic parasitic twin is incorporated into the body of its fellow twin and grows inside it. FIF is differentiated from teratoma by the presence of vertebral column. An eight year old girl presented with an abdominal swelling which by X-ray, ultrasonography and CT scan revealed a fetiform mass containing long bones and vertebral bodies surrounded by soft tissue situated on right lumber region. On laparotomy, a retroperitoneal mass resembling a fetus of 585 gm was removed. It had a trunk and four limbs with fingers and toes, umbilical stump, intestinal loops and abundant scalp hairs but was devoid of brain and heart. Histology showed various well-differentiated tissues in respective sites. FIF is a mystery in reproduction and it is scarce in literature in such well-developed stage.

  2. Mystery of the First Russian Rifle Naval Guns

    2015-09-01

    Full Text Available In 1859 France completed the first ocean-going ironclad warship, «La Gloire», and changed the definition of naval power completely. Russia, as all the other Powers, found that her most powerful naval gun, the 60-pdr, was insufficient for modern warfare, and realized the future naval armament relied on heavy rifled artillery. Both the Army and Navy began purchasing such cannon from foreign providers until a suitable domestic weapon could be produced. The relationship between the Russian military and Krupp is well known. But there was another provided, the Blakely Ordnance Company in England sold many guns to the Army and Navy, beginning with 8-inch MLR in early 1863 to a large number of 9- and 11-inch guns. Deliveries began in November 1863 and continued until mid-1866. But no sources on the armament of Russian ships and fortresses mentions these guns. What happened to them is a mystery.

    The Trapped Gyro-Landau Fluid (TGLF) quasi-linear model [G. M. Staebler, et al., Phys. Plasmas 12, 102508 (2005)], which is calibrated to nonlinear gyrokinetic turbulence simulations, is now able to predict the electron density, electron and ion temperatures, and ion toroidal rotation simultaneously for internal transport barrier (ITB) discharges. This is a strong validation of gyrokinetic theory of ITBs, requiring multiple instabilities responsible for transport in different channels at different scales. The mystery of transport inside the ITB is that momentum and particle transport is far above the predicted neoclassical levels in apparent contradiction with the expectation from the theory of suppression of turbulence by E×B velocity shear. The success of TGLF in predicting ITB transport is due to the inclusion of ion gyro-radius scale modes that become dominant at high E×B velocity shear and to improvements to TGLF that allow momentum transport from gyrokinetic turbulence to be faithfully modeled.

  6. A Missing Link in Galaxy Evolution: The Mysteries of Dissolving Star Clusters

    2007-05-01

    Star-forming events in starbursts and normal galaxies have a direct impact on the global stellar content of galaxies. These events create numerous compact clusters where stars are produced in great number. These stars eventually end up in the star field background where they are smoothly distributed. However, due to instrumental limitations such as spatial resolution and sensitivity, the processes involved during the transition phase from the compact clusters to the star field background as well as the impact of the environment (spiral waves, bars, starburst) on the lifetime of clusters are still poorly constrained observationally. I will present our latest results on the physical properties of dissolving clusters directly detected in HST/ACS archival images of the three nearby galaxies IC 2574, NGC 1313, and IC 10 (D detect and spatially resolve individual stars in nearby galaxies within a large field-of-view. For all ACS images obtained in three filters (F435W, F555W or F606W, and F814W), we performed PSF stellar photometry in crowded field. Color-magnitude diagrams (CMD) allow us to identify the most massive stars more likely to be part of dissolving clusters (A-type and earlier), and to isolate them from the star field background. We then adapt and use a clustering algorithm on the selected stars to find groups of stars to reveal and quantify the properties of all star clusters (compactness, size, age, mass). With this algorithm, even the less compact clusters are revealed while they are being destroyed. Our sample of three galaxies covers an interesting range in gravitational potential well and explores a variety of galaxy morphological types, which allows us to discuss the dissolving cluster properties as a function of the host galaxy characteristics. The properties of the star field background will also be discussed.

  7. Consolidity: Mystery of inner property of systems uncovered

    Directory of Open Access Journals (Sweden)

    Hassen T. Dorrah

    2012-10-01

    Full Text Available This paper uncovers the mystery of consolidity, an inner property of systems that was amazingly hidden. Consolidity also reveals the secrecy of why strong stable and highly controllable systems are not invulnerable of falling and collapsing. Consolidity is measured by its Consolidity Index, defined as the ratio of overall changes of output parameters over combined changes of input and system parameters, all operating in fully fuzzy environment. Under this notion, systems are classified into consolidated, quasi-consolidated, neutrally consolidated, unconsolidated, quasi-unconsolidated and mixed types. The strategy for the implementation of consolidity is elaborated for both natural and man-made existing systems as well as the new developed ones. An important critique arises that the by-product consolidity of natural or built-as-usual system could lead to trapping such systems into a completely undesired unconsolidity. This suggests that the ample number of conventional techniques that do not take system consolidity into account should gradually be changed, and adjusted with improved consolidity-based techniques. Four Golden Rules are highlighted for handling system consolidity, and applied to several illustrative case studies. These case studies cover the consolidity analysis of the Drug Concentration problem, Predator-Prey Population problem, Spread of Infectious Disease problem, AIDS Epidemic problem and Arm Race model. It is demonstrated that consolidity changes are contrary (opposite in sign to changes of both stability and controllability. This is a very significant result showing that our present practice of stressing on building strong stable and highly controllable systems could have already jeopardized the consolidity behavior of an ample family of existing real life systems. It is strongly recommended that the four Golden Rules of consolidity should be enforced as future strict regulations of systems modeling, analysis, design and

  10. Emanations and 'induced' radioactivity: from mystery to (mis)use

    International Nuclear Information System (INIS)

    Kolar, Z.I.

    1999-01-01

    The natural Rn isotopes were discovered within the period 1899-1902 and at that time referred to as emanations because they came out (emanated) of sources/materials containing actinium, thorium and radium, respectively. The (somewhat mysterious) emanations appeared to disintegrate into radioactive decay products which by depositing at solid surfaces gave rise to 'induced' radioactivity i.e. radioactive substances with various half-lives. Following the discovery of the emanations the volume of the research involving them and their disintegration products grew steeply. The identity of a number of these radioactive products was soon established. Radium emanation was soon used as a source of RaD ( 210 Pb) to be applied as an 'indicator' (radiotracer) for lead in a study on the solubility of lead sulphide and lead chromate. Moreover, radium and its emanation were introduced into the medical practice. Inhaling radon and drinking radon-containing water became an accepted medicinal use (or misuse?) of that gas. Shortly after the turn of the century, the healing (?) action of natural springs (spas) was attributed to their radium emanation, i.e. radon. Bathing in radioactive spring water and drinking it became very popular. Even today, bathing in radon-containing water is still a common medical treatment in Jachymov, Czech Republic. (author)

    Gott, J Richard

    2016-01-01

    J. Richard Gott was among the first cosmologists to propose that the structure of our universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies—a magnificent structure now called the "cosmic web" and mapped extensively by teams of astronomers. Here is his gripping insider’s account of how a generation of undaunted theorists and observers solved the mystery of the architecture of our cosmos. The Cosmic Web begins with modern pioneers of extragalactic astronomy, such as Edwin Hubble and Fritz Zwicky. It goes on to describe how, during the Cold War, the American school of cosmology favored a model of the universe where galaxies resided in isolated clusters, whereas the Soviet school favored a honeycomb pattern of galaxies punctuated by giant, isolated voids. Gott tells the stories of how his own path to a solution began with a high-school science project when he was eighteen, and how he and astronomer Mario Jurič measured the Sloan Great Wall of Galaxies, a fi...

In addition, we shall refute the claim that recently appeared in the physics literature that the Detweiler-Teukolsky-Press resonance equation for the characteristic gravitational eigenfrequencies of rapidly-rotating Kerr black holes is not valid in the regime of damped quasinormal resonances with ℑω/T_B_H≫1 (here ω and T_B_H are respectively the characteristic quasinormal resonant frequency of the Kerr black hole and its Bekenstein-Hawking temperature). The main goal of the present paper is to highlight and expose this important black-hole quasinormal mystery (that is, the intriguing discrepancy between the analytical and numerical results regarding the gravitational quasinormal resonance spectra of rapidly-rotating Kerr black holes).

  15. Staging Icons, Performing Storyworlds – From Mystery Play to Cosplay

    2014-12-01

    Full Text Available One of the oldest complex forms of intermediality is the static live-performance adaptation of the iconographic qualities of well-known stories. Early examples of this phenomenon are the depictions of biblical scenes in the form of grand (and largely static tableaux in medieval Mystery Plays, very popular until the emergence of the professional entertainment stage. The nineteenth century had its fascination with the tableaux vivants - not coincidentally during the time that photography was introduced - and the late twentieth century saw the beginning of the newest variety with cosplay, which has by now become a global cultural phenomenon. Cosplay, the activity of fans dressing up and posing in a visually recognizable way as characters from popular media franchises such as manga, anime, or TV series, developed from role-playing activities into its current, highly ritualized static form through its symbiosis with amateur photography. This paper wants to first analyse the underlying art form in its historical varieties from an intermedial perspective, and in connection with that, it will explore the deeper philosophical significance of this practice, looking particularly at the role of embodiment.

    Citizen Sky is a multi-year, NSF funded citizen science project involving the bright star eps Aur. The project was conceived by the IYA 2009 working group on Research Experiences for Students, Teachers, and Citizen-Scientists. Citizen Sky goes beyond simple observing to include a major data analysis component. The goal is to introduce the participant to the full scientific process from background research to paper writing for a peer-reviewed journal. It begins with a 10 Star Training Program of several types of binary and transient variable stars that are easy to observe from suburban locations with the naked eye. Participants then move on to monitoring the rare and mysterious 2009-2011 eclipse (already underway) of epsilon Aurigae. This object undergoes eclipses only every 27.1 years and each eclipse lasts nearly two years. The star is bright enough to be seen with the naked eye from most urban areas. Training will be provided in observing techniques as well as basic data analysis of photometric and visual datasets (light curve and period analysis). The project also involves two public workshops, one on observing (already held in August of 2009) and one on data analysis and scientific paper writing (to be held in 2010.) This project has been made possible by the National Science Foundation.

  17. Mysteries of attraction: Giovanni Pico della Mirandola, astrology and desire.

    2010-06-01

    Although in his later years Giovanni Pico della Mirandola (1463-1494) vehemently rejected astrology, he earlier used it in a variety of ways, but primarily to provide further evidence for positions to which he had arrived by other means. One such early use appears in his commentary on his friend Girolamo Benivieni's love poetry, the Canzone d'amore, of 1486-1487. In the passages discussed here, Pico presents an intensive Platonic natural philosophical analysis based on a deep astrologically informed understanding of human nature as he attempts to explain a perennial question, namely, why one person is attracted to a certain person (or people), and another to others. I will place this discussion of the mysteries of attraction and desire in historical perspective by tracing Pico's changing relationship to astrology during the course of his short but passionate life, and in historiographic perspective by revising Frances Yates's still influential views concerning Pico's contribution to Renaissance thought and his relationship with Marsilio Ficino.

  18. The mysterious world of plutonium metallurgy: Past and future

    1998-01-01

    The first atomic bomb detonated at the Trinity Site in New Mexico on July 16, 1945, used plutonium, a man-made element discovered < 5 yr earlier. The story of how Manhattan Project scientists and engineers tackled the mysteries of this element and fabricated it into the first atomic bomb is one of the most fascinating in the history of metallurgy and materials. The authors are currently trying to generate renewed interest in plutonium metallurgy because of the challenge posed by President Clinton, i.e., to keep the nuclear stockpile of weapons safe and reliable without nuclear testing. The stockpile stewardship challenge requires either a lifetime extension of the plutonium components or a remanufacture--neither of which can be verified by testing. In turn, this requires that one achieve a better fundamental understanding of plutonium. Of special interest is the effect of self-irradiation on the properties and on the long-term stability of plutonium and its alloys. Additional challenges arise from long-term concerns about disposing of plutonium and dealing with its environmental legacy. It is imperative to interest the next generation of students in these plutonium challenges

  19. Hidden Attraction - The History and Mystery of Magnetism

    Science.gov (United States)

    Verschuur, Gerrit L.

    1996-04-01

    Long one of nature's most fascinating phenomena, magnetism was once the subject of many superstitions. Magnets were thought useful to thieves, effective as a love potion, and as a cure for gout or spasms. They could remove sorcery from women and put demons to flight and even reconcile married couples. It was said that a lodestone pickled in the salt of sucking fish had the power to attract gold. Today, these beliefs have been put aside, but magnetism is no less remarkable for our modern understanding of it. In Hidden Attraction , Gerrit L. Verschuur, a noted astronomer and National Book Award nominee for The Invisible Universe , traces the history of our fascination with magnetism, from the mystery and superstition that propelled the first alchemical experiments with lodestone, through the more tangible works of Faraday, Maxwell, Hertz and other great pioneers of magnetism (scientists responsible for the extraordinary advances in modern science and technology, including radio, the telephone, and computers, that characterize the twentieth century), to state-of-the-art theories that see magnetism as a basic force in the universe. Boasting many informative illustrations, this is an adventure of the mind, using the specific phenomenon of magnetism to show how we have moved from an era of superstitions to one in which the Theory of Everything looms on the horizon.

    Merle, Alexander

    2009-12-09

    This doctoral thesis deals with the mysteries of the leptonic sector of the Standard Model of Elementary Particle Physics. After giving a short overview about the Standard Model itself, the text starts with introducing the so-called ''GSI anomaly'', the observation of a periodic modulation of the exponential decay law, which is still unexplained and has erroneously been attributed to neutrino oscillations. It is argued why this interpretation is incorrect and several further aspects of the phenomenon are discussed. Afterwards two topics of New Physics beyond the Standard Model are treated, double beta processes and lepton flavour violation. Some important phenomenological aspects of the former are discussed before performing a detailed calculation of the radiative process of neutrino-less double electron capture. In spite of the tiny rates, a detailed understanding of this process is important for setting proper experimental limits. The last part of the thesis starts with very general (and nearly model-independent) constraints for lepton flavour conservation, before discussing the interplay of structure and freedom in the Yukawa sector when a model is confronted with phenomenology. We also comment on a new mechanism that can indeed introduce some realistic structures leading to lepton flavour violating effects. (orig.)

    2003-01-01

    The authors described the mysterious oil spill which occurred in the Detroit River in 2002. Advanced chemical fingerprinting and data interpretation techniques were conducted on spill samples collected by Environment Canada, Ontario Region, to determine the chemical composition of the oil and find out where it came from. The objective was to gather information concerning the nature, type, and components of the spill samples. The authors checked if the samples were identical to determine if they originated from the same source. They used a tiered analytical approach which facilitates the detailed compositional analysis by gas chromatograph-mass spectrometer (GC-MS) and GC-flame ionization detection (FID). A wide range of diagnostic ratios of source-specific marker compounds for interpreting chemical data was determined and analyzed. The results proved that: (1) the spill samples were largely composed of lube oil mixed with a smaller portion of diesel fuel, (2) sample number 3 collected from N. Boblo Island was more weathered than samples 1 and 2, (3) the oil in three samples was the same and originated from the same source, as shown by fingerprinting results, (4) most PAH compounds were from the diesel portion in the spill samples, and the biomarker compounds were mostly from the lube oil, (5) the diesel in the samples had been weathered and degraded, and the lube oil in the spill samples was waste lube oil, and (6) input of pyrogenic PAHs to the spill samples was clearly proven. The spill likely came from a place where both combustion and motor lubrication processes occur. 46 refs., 4 tabs., 6 figs

    2006-01-01

    The purpose of the study was to evaluate the accessibility of, and advice provided by, sexual health and advice services for young people in Croydon, UK using a 'mystery shopper' approach. Nineteen young people aged 13-21 years were trained as mystery shoppers. The group developed a set of standards, based in part on existing guidelines of best practice, that should be met when working with young people. The group accessed local sexual health services in pairs posing as genuine patients. Using one of four scenarios, the mystery shoppers assessed the service they received against the predefined standards. The main access difficulties occurred in the reception area. Confidentiality was a major concern and was frequently not explained. The advice and information received was generally clearly given and with an appropriate level of detail. Additional training and support needs to be offered to receptionists. Confidentiality policies and statements need to be more effectively communicated.

  5. Dark Matter Mystery Deepens in Cosmic "Train Wreck"

    Science.gov (United States)

    2007-08-01

    Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wreck" between giant galaxy clusters. NASA's Chandra X-ray Observatory and optical telescopes revealed a dark matter core that was mostly devoid of galaxies, which may pose problems for current theories of dark matter behavior. "These results challenge our understanding of the way clusters merge," said Dr. Andisheh Mahdavi of the University of Victoria, British Columbia. "Or, they possibly make us even reexamine the nature of dark matter itself." There are three main components to galaxy clusters: individual galaxies composed of billions of stars, hot gas in between the galaxies, and dark matter, a mysterious substance that dominates the cluster mass and can be detected only through its gravitational effects. Illustration of Abell 520 System Illustration of Abell 520 System Optical telescopes can observe the starlight from the individual galaxies, and can infer the location of dark matter by its subtle light-bending effects on distant galaxies. X-ray telescopes like Chandra detect the multimillion-degree gas. A popular theory of dark matter predicts that dark matter and galaxies should stay together, even during a violent collision, as observed in the case of the so-called Bullet Cluster. However, when the Chandra data of the galaxy cluster system known as Abell 520 was mapped along with the optical data from the Canada-France-Hawaii Telescope and Subaru Telescope atop Mauna Kea, HI, a puzzling picture emerged. A dark matter core was found, which also contained hot gas but no bright galaxies. "It blew us away that it looks like the galaxies are removed from the densest core of dark matter," said Dr. Hendrik Hoekstra, also of University of Victoria. "This would be the first time we've seen such a thing and could be a huge test of our knowledge of how dark matter behaves."

    Full Text Available John Searle repeatedly claims to have offered a solution to the mind-brain problem, especially as regards the mystery of consciousness. The aim of this paper is to present and analyse Searle’s theory of biological naturalism, from its earliest expression in the 1980s to his most recent works. Our analysis shows that Searle’s biological naturalism suffers from many theoretical difficulties and logical inconsistencies, which disqualify it as a sound explanation for consciousness and the mind-brain problem. We conclude that, far from offering a solution to the problem of consciousness, Searle ended up creating a new mystery of consciousness.

  9. Venus Express en route to probe the planet's hidden mysteries

    mechanics of the planetary atmosphere in general terms. With Mars Express, we are studying the Martian atmosphere. With Huygens, we have explored that of Saturn's satellite Titan. And now with Venus Express, we are going to add a further specimen to our collection. Originally, Venus and the Earth must have been very similar planets. So we really do need to understand why and how they eventually diverged to the point that one became a cradle for life while the other developed into a hostile environment." The Venus Express mission is planned to last at least two Venusian days (486 Earth days) and may be extended, depending on the spacecraft's operational state of health. Twin sister of Mars Express Venus Express largely reuses the architecture developed for Mars Express. This has reduced manufacturing cycles and halved the mission cost, while still targeting the same scientific goals. Finally approved in late 2002, Venus Express was thereby developed fast, indeed in record time, to be ready for its 2005 launch window. However, Venusian environmental conditions are very different to those encountered around Mars. Solar flux is four times higher and it has been necessary to adapt the spacecraft design to this hotter environment, notably by entirely redesigning the thermal insulation. Whereas Mars Express sought to retain heat to enable its electronics to function properly, Venus Express will in contrast be aiming for maximum heat dissipation in order to stay cool. The solar arrays on Venus Express have been completely redesigned. They are shorter and are interspersed with aluminium strips to help reject some solar flux to protect the spacecraft from temperatures topping 250ºC. It has even been necessary to protect the rear of the solar arrays - which normally remain in shadow - in order to counter heat from solar radiation reflected by the planet's atmosphere.

    The Chinese mystery snail (Bellamya chinensis) is an aquatic invasive species in North America. Little is known regarding this species' impacts on freshwater ecosystems. It is be lieved that population densities can be high, yet no population estimates have been reported. We utilized a mark-recapture approach to generate a population estimate for Chinese mystery snail in Wild Plum Lake, a 6.47-ha reservoir in southeast Nebraska. We calculated, using bias-adjusted Lincoln-Petersen estimation, that there were approximately 664 adult snails within a 127 m2 transect (5.2 snails/m2). If this density was consistent throughout the littoral zone (Chinese mystery snail wet biomass is estimated to be 3,119 kg (643 kg/ha). If this density is confined to the depth sampled in this study (1.46 m), then the adult population is estimated to be 169,400 snails, and wet biomass is estimated to be 2,084 kg (643 kg/ha). Additional research is warranted to further test the utility of mark-recapture methods for aquatic snails and to better understand Chinese mystery snail distributions within reservoirs.

    Making an extra effort to image a faint, gigantic corkscrew traced by fast protons and electrons shot out from a mysterious microquasar paid off for a pair of astrophysicists who gained new insights into the beast's inner workings and also resolved a longstanding dispute over the object's distance. Microquasar SS 433 VLA Image of Microquasar SS 433 CREDIT: Blundell & Bowler, NRAO/AUI/NSF (Click on Image for Larger Version) The astrophysicists used the National Science Foundation's Very Large Array (VLA) radio telescope to capture the faintest details yet seen in the plasma jets emerging from the microquasar SS 433, an object once dubbed the "enigma of the century." As a result, they have changed scientists' understanding of the jets and settled the controversy over its distance "beyond all reasonable doubt," they said. SS 433 is a neutron star or black hole orbited by a "normal" companion star. The powerful gravity of the neutron star or black hole draws material from the stellar wind of its companion into an accretion disk of material tightly circling the dense central object prior to being pulled onto it. This disk propels jets of fast protons and electrons outward from its poles at about a quarter of the speed of light. The disk in SS 433 wobbles like a child's top, causing its jets to trace a corkscrew in the sky every 162 days. The new VLA study indicates that the speed of the ejected particles varies over time, contrary to the traditional model for SS 433. "We found that the actual speed varies between 24 percent to 28 percent of light speed, as opposed to staying constant," said Katherine Blundell, of the University of Oxford in the United Kingdom. "Amazingly, the jets going in both directions change their speeds simultaneously, producing identical speeds in both directions at any given time," Blundell added. Blundell worked with Michael Bowler, also of Oxford. The scientists' findings have been accepted by the Astrophysical Journal Letters. SS 433 New VLA

    Full Text Available Leptospirosis is an emerging infectious disease which has been recognized as the most common zoonotic infection in the world. It affects human beings and many other species of vertebrates .Most commonly, the infection is acquired by direct or indirect exposure to urine of reservoir animals through contaminated soil, mud & water entering via small abrasions or breaches in the skin & mucous membranes during occupational, recreational or vocational activities. The signs & symptoms resemble a wide range of bacterial & viral diseases & sometimes can present as food poisoning, chemical poisoning & snake bite also due to which the diagnosis is often missed. This review article aims to focus on the role of Dark Field Microscopy (DFM, culture, Enzyme Linked Immuno Sorbent Assay (ELISA, Macroscopic Slide Agglutination test (MSAT, Microscopic Agglutination Test (MAT and Faine’s criteria in the diagnosis of leptospirosis.

    A mystery spill, or an oil spill of unknown origin, is one whose source cannot be identified at the time the environmental impact of the spill is noted. Unlike a known incident during which preventive action may be taken, mystery spills are often assessed based on the damages they have caused. In Canada, the coast guard regularly reports many spills with unidentified sources, and the most frequently reported sign of a spill is the presence of an oily film on the water surface. The smell of oil is also an important indication of a recent spill. The spill at Baie-des-Sables, Quebec, is presented as an illustrative example of a mystery spill. The size of the spill was estimated at 25 tons of bunker oil. The first indication of the spill was a number of contaminated ducks from the Rimouski region, reported by hunters to the appropriate government agency. Two days later, an oil slick was reported in the channel between Baie-Comeau and Rimouski; this provided sufficient information to trigger an alert. The next day an aerial inspection of the slick was carried out and a dispersion model was made. Contamination of seagulls and the south shore of the St. Lawrence River were noted. Over the next week response measures were organized and more inspections of shorelines were undertaken. Of the shoreline studied, 50 km were contaminated and 14 km were restored. Lack of precise early observations of the slick precluded identification of the vessel responsible for the spill. Recommendations are made for improving assessment of mystery spills and ensuring faster response times. 1 fig

  5. Energy and Technology Review: Unlocking the mysteries of DNA repair

    1993-04-01

    DNA, the genetic blueprint, has the remarkable property of encoding its own repair following diverse types of structural damage induced by external agents or normal metabolism. We are studying the interplay of DNA damaging agents, repair genes, and their protein products to decipher the complex biochemical pathways that mediate such repair. Our research focuses on repair processes that correct DNA damage produced by chemical mutagens and radiation, both ionizing and ultraviolet. The most important type of DNA repair in human cells is called excision repair. This multistep process removes damaged or inappropriate pieces of DNA -- often as a string of 29 nucleotides containing the damage -- and replaces them with intact ones. We have isolated, cloned, and mapped several human repair genes associated with the nucleotide excision repair pathway and involved in the repair of DNA damage after exposure to ultraviolet light or mutagens in cooked food. We have shown that a defect in one of these repair genes, ERCC2, is responsible for the repair deficiency in one of the groups of patients with the recessive genetic disorder xeroderma pigmentosum (XP group D). We are exploring ways to purify sufficient quantities (milligrams) of the protein products of these and other repair genes so that we can understand their functions. Our long-term goals are to link defective repair proteins to human DNA repair disorders that predispose to cancer, and to produce DNA-repair-deficient mice that can serve as models for the human disorders.

  6. Developing a Mystery Shopping Measure to Operate a Sustainable Restaurant Business: The Power of Integrating with Corporate Executive Members’ Feedback

    Rachel J. C. Chen

    2015-09-01

    Full Text Available Mystery shopping has been used to objectively measure whether employees follow the visions of a company’s quality service standards. It then creates a feedback loop that allows companies to train their employees to consistently deliver quality services. The main purposes of this project are aimed at examining (1 the overall benefits of mystery shopper projects in the hospitality business through literature reviews; and (2 the importance of how a company can work with an outside agency (consultant, academic institution, etc. to develop a mystery shopping program that can enhance and complement ongoing service quality programs. A casual steakhouse restaurant in the Eastern U.S. was selected as our pilot project. The basic concept of using secret shoppers is to have individuals experience real-time and onsite quality of services and record how the mystery shoppers felt about the quality of services and if the employees met or exceeded the company’s standards. For this reason, the authors believe that mystery shopping, especially in hospitality, is an important means of developing and maintaining a sustainable business. While the sustainability of a business is largely dependent upon “people, profits and planet” in the hospitality industry, it is also dependent upon meeting service standards and developing a feedback loop. Mystery shopping programs have demonstrated their ability to contribute to organizations in this regard.

    The LHC accelerator at CERN will be completed soon and the experiments are about to start, making it possible to explore the TeV energy region for the first time in human history. There exists a clear reason why the TeV region is especially important for experimental exploration. The Higgs particle, the last elusive element of the Standard Model, will be discovered with very high probability. In addition there are high chances to discover signs of new physics beyond the Standard Model such as SUSY particles. Dark matter may be discovered. As an introduction of the mini-special issue for LHC, its goals and history is briefly reviewed, followed by a description on LHC accelerator, four LHC experiments as well as the contributions by Japan.

    The bulk of observed ultrahigh-energy cosmic rays could be light or heavier elements and originate from an either steady or transient population of sources. This leaves us with four general categories of sources. Energetic requirements set a lower limit on single-source luminosities, while the distribution of particle arrival directions in the sky sets a lower limit on the source number density. The latter constraint depends on the angular smearing in the skymap due to the magnetic deflections of the charged particles during their propagation from the source to the Earth. We contrast these limits with the luminosity functions from surveys of existing luminous steady objects in the nearby universe and strongly constrain one of the four categories of source models, namely, steady proton sources. The possibility that cosmic rays with energy >8 × 10{sup 19} eV are dominantly pure protons coming from steady sources is excluded at 95% confidence level, under the safe assumption that protons experience less than 30° magnetic deflection on flight.

    In the last decade there was under debate the issue concerning the composition of the ultra high energy cosmic rays and some authors suggested that the light composition seems to be a relating issue. There was another debate concerning the limit of the energy of gamma rays. The bottom-up approaches suggest a limit at 10 15 eV. Some top-down approaches rise this limit at about 10 20 eV or above. The present paper provides an approach to estimate the limit of the energy of gamma rays using the recent paper of Claus W. Turtur. (author)

    them for downlink to Earth at the next ground station contact. ESA has installed a new deep-space antenna at New Norcia, near Perth in Western Australia, as the main communications link between the spacecraft and the ESOC Mission Control in Darmstadt, Germany. This 35-metre diameter parabolic antenna allows the radio signal to reach distances of more than 1 million kilometres from Earth. The radio signals, travelling at the speed of light, will take up to 50 minutes to cover the distance between the spacecraft and Earth. Rosetta's Science Operations Centre, which is responsible for collecting and distributing the scientific data, will share a location at ESOC and ESTEC in Noordwijk, The Netherlands. The Lander Control Centre is located in DLR in Cologne, Germany, and the Lander Science Centre in CNES in Toulouse, France. Building Rosetta Rosetta was selected as a mission in 1993. The spacecraft has been built by Astrium Germany as prime contractor. Major subcontractors are Astrium UK (spacecraft platform), Astrium France (spacecraft avionics), and Alenia Spazio (assembly, integration, and verification). Rosetta’s industrial team involves more than 50 contractors from 14 European countries, Canada and the United States. Scientific consortia from institutes across Europe and the United States have provided the instruments on the orbiter. A European consortium under the leadership of the German Aerospace Research Institute (DLR) has provided the lander. Rosetta has cost ESA Euro 701 million at 2000 economic conditions. This amount includes the launch and the entire period of development and mission operations from 1996 to 2013. The lander and the experiments, the so-called 'payload', are not included since they are funded by the member states through the scientific institutes. Note to editors Europe is certainly a pioneer in comet exploration. In 1986, ESA’s spacecraft Giotto performed the closest comet fly-by ever achieved by any spacecraft (at a distance of 600

Problems such as the nonexistence of a script and the way the film seems structured by oral narration, in loco, as if the film were being written as it is told, will be analyzed. Finally, I describe how, through this structure, the film reflects upon the specificity of cinema as a way of telling/showing stories.

    2017-01-01

    I saw something extraordinary on Wednesday, 25 September 2013, at about 10:10AM local time, while in a parking lot at the NASA Goddard Space Flight Center in Greenbelt, Maryland USA (located in the suburbs of Washington, D.C., about 20 km northeast of the White House). I looked northeast at about a 45 degree angle at a cirrus cloud. The cloud was elongated horizontally from my perspective. T o my surprise I saw a band of ripples rapidly pass from right to left along the axis of the cloud. The ripples appeared dark, like a bar code, with the bars being almost vertical (see Figure 1). There appeared to be approximately 10 bars in the band. Each bar was a few degrees in length. I estimate that each bar was about 1/10 to 1/4 degree in width and the white spaces between them about the same width. I guessed that the angular speed of the band passing along the cloud was about 1/2 to 1 degree per second. A half-moon was in another part of the sky; looking at the Moon later helped me make the estimates. After a few seconds at most the band disappeared. Then a second band repeated the performance. I kept watching to see if this was going to be a periodic phenomenon, but no further bands appeared; just the two. Of course there may have been other bands passing across the cloud before I started looking. About 30 seconds to a minute after the bands disappeared, a low-flying jetliner on the usual northeast to southwest route passed almost exactly through the spot where I had seen the bands. I estimate the jetliner was a bit bigger than the full moon. My first thought was that maybe there was something wrong inside my eyes. But looking at other clouds revealed no bands. So what caused the bands? They do not seem to have been due to the exhausts on top of the nearby building, with the cloud acting as a backdrop: one would expect a continuous, disorganized shimmering instead of two separate organized bands. Moreover, there would be no reason for bands to stop unless the exhausts suddenly stopped right while I was looking at the cloud. Hence the explanation does not seem to be local. This or a similar phenomenon was photographed in France during World War II, apparently produced by distant artillery. Jones (1947) proffered the explanation that shock waves from the guns were made visible in the sky by a process akin to Schlieren photography, with the cloud apparently acting as a screen against which to view the waves. The photograph shows 3 bars, compared to the 10 or so I saw. Rather than the cloud just being a backdrop, Andrew T. Young of San Diego State University and my colleague Coerte Voorhies (private communications) point out that the bands may have been made in the cloud itself. A passing disturbance jostling the ice crystals in the cloud would change the reflection of sunlight to the observer, giving the light and dark pattern. Assuming Young and Voorhies are correct, what made the disturbance? Cirrus clouds range from approximately 4 km to approximately 13 km in height. A cloud at a 45 degree angle would be 5.7 km to 18.4 km away. For my estimated angular speeds of 1/2 to 1 degree per second and the range of cirrus heights, the linear speeds range from approximately 100 m s(exp -1)-1 to approximately 642 m s(exp -1), which is subsonic to supersonic. Supersonic speed is unlikely. Young suggests that if the disturbance was subsonic, then it may have been due to the twin vortices produced, not by the jet I saw a half-minute to a minute later, but by a previous jet on the populous route. Twin vortices would explain two bands. On the other hand, if the bands were sound waves traveling at the speed of sound, approximately 343 m s(exp -1), Voorhies notes that the range of estimated distances to the cloud and the estimated center-to-center spacing of 1/5 to 1/2 degrees between the bars give frequencies between approximately 5 Hz and approximately 17 Hz. This is in the infrasound range. Possibly a jet or other man-made disturbance produced infrasound. Another possibility is the passage of a large meteorite. The American Meteor Society reported that September 2013 was a busy month for bright meteors (http://earthsky.org/earth/u-smidwest- sees-another-bright-fireball). However, no daylight meteor was noticed near the appropriate place and time, and such a large meteor going undetected except for a lucky sighting of its infrasound signature in a cirrus cloud seems unlikely. I thank Andrew T. Young and Coerte Voorhies for their input.

    Full Text Available A 69-year-old man presented with multiple spontaneous bruises in the past 2 weeks. Several large-sized hematomas were found on examination. The initial investigation revealed a prolonged activated partial thromboplastin time (aPTT with normal platelet count and international normalized ratio. Further investigation revealed a low factor VIII activity secondary to presence of factor VIII inhibitor, making the diagnosis of acquired hemophilia A. Further work-up revealed that pernicious anemia was present and acted as an associated disease. After steroids therapy, his aPTT was normalized and the factor VIII inhibitor titer became undetectable. 2 months later, a relapse occurred and new hematomas appeared at his retropharyngeal space and left arm. His bleeding was controlled by administration of recombinant factor VIIa, and a combined therapy of intravenous steroids and rituximab was given to eradicate the inhibitor. The approach to workup of bleeding disorders as well as treatment of acquired hemophilia A are herein discussed.

    Mystery shops (MS) involving attempted tobacco purchases by young buyers have been employed to monitor retail stores’ performance in refusing underage sales. Anecdotal evidence suggests that MS visits with immediate feedback to store personnel can improve age verification. This study investigated the impact of monthly and twice-monthly MS reports on age verification. Forty-five Walgreens stores were each visited 20 times by mystery shoppers. The stores were randomly assigned to one of three conditions. Control group stores received no feedback, whereas two treatment groups received feedback communications every visit (twice monthly) or every second visit (monthly) after baseline. Logit regression models tested whether each treatment group improved verification rates relative to the control group. Post-baseline verification rates were higher in both treatment groups than in the control group, but only the stores receiving monthly communications had a significantly greater improvement than control group stores. Verification rates increased significantly during the study period for all three groups, with delayed improvement among control group stores. Communication between managers regarding the MS program may account for the delayed age-verification improvements observed in the control group stores. Encouraging inter-store communication might extend the benefits of MS programs beyond those stores that receive this intervention. PMID:21541874

    Full Text Available Aside from the nature of consciousness itself, there are still many unsolved problems in the neurosciences. Despite the vast and quickly growing body of work in this field, we still find ourselves perplexed at seemingly simple qualities of our mental being such as why we need to sleep. The neurosciences are at least beginning to take a hold on these mysteries and are working toward solving them. We hold a perspective that metastable consciousness models, specifically the Default Space Model (DSM, provide insights into these mysteries. In this perspective article, we explore some of these curious questions in order to elucidate the interesting points they bring up. The DSM is a dynamic, global theory of consciousness that involves the maintenance of an internal, 3D simulation of the external, physical world which is the foundation and structure of consciousness. This space is created and filled by multiple frequencies of membrane potential oscillations throughout the brain and body which are organized, synchronized and harmonized by the thalamus. The veracity of the DSM is highlighted here in its ability to further understanding of some of the most puzzling problems in neuroscience.

    Full Text Available Background: Although emergency contraceptive pills are available over the counter, the quality of consultation, including key areas of contraceptive counseling and prevention of sexually transmitted infections (STI, has not been well documented. Objective: To evaluate actual pharmacist services while dispensing emergency contraception through a mystery shopper technique. Material and Methods: This cross-sectional study was conducted in 81 pharmacies situated in Delhi by 4 trained mystery shoppers posed as customers over a period of 6 months. Results: None of the pharmacists asked about the time lapsed since last unprotected sexual intercourse or last menstrual period before deciding the eligibility of the customer. The majority were unclear about side effects associated with emergency contraception (78.57% or with anticipated changes in menstrual flow (78.57%; 85.71% did not know whether subsequent unprotected intercourse would be protected. Only 15.71% counseled shoppers regarding risk of STI on asking leading questions and 88.5% did not provide any contraceptive advice. Conclusion: There is a huge gap in the technical knowledge and mindset of the pharmacists when it comes to checking for the eligibility of the client and providing advice regarding use of regular contraception and barrier for protection from STI, which needs to be addressed in order to realize the full benefit of making emergency contraceptive pills available over the counter.

    To explore the availability and provision of misoprostol and other medicines for menstrual regulation (MR) among pharmacies in Bangladesh. Between March and November 2011, a cross-sectional study using mystery client visits was conducted among pharmacy workers in Dhaka and Gazipur Districts, Bangladesh. Mystery clients were trained to present 1 of 4 pre-developed situations to pharmacy workers to elicit information on the regimen, adverse effects, and complications of misoprostol use. Mystery clients visited 331 pharmacies. Among the 331 pharmacy workers, 45.8% offered the mystery clients misoprostol and/or other medicines for MR; 25.7% referred them to private clinics or hospitals. Only 7% recommended an effective regimen of misoprostol for MR; 65% suggested administering vaginal and oral misoprostol together. Overall, 72.4% did not provide any advice on complications; the remainder suggested visiting trained providers for complications. Counseling on excessive bleeding as a danger sign was provided by 46% of pharmacy workers. Most (94%) did not provide or refer for post-MR family planning. Pharmacy workers in urban Bangladesh are providing ineffective drugs and regimens for MR. A training package is needed to strengthen service delivery by providing accurate information, high-quality products, and referral mechanisms for women seeking MR through pharmacies. © 2013.

Its goal is to introduce them to some of the main topics of the Solar System: a) the role of gravity; b) the distribution of mass & light; c) the effects of rotation; d) the distribution of water. The game was held both at the Perugia (2004) and the Genova Science Festival (2005), obtaining great success. Teams of about 6-8 members are introduced to Mr Schioppanelli, the astro-detective of the town (the name is a pun: it reminds Schiaparelli, the famous italian astronomer, and it is a slang expression meaning "ring-breaker"). Mr Schioppanelli has his office in an "gastronomical astronomical observatory", known as The Red Giant Pizzeria. Schioppanelli informs the kids that a mysterious Centaur succeded in stealing the rings of Saturn. The partecipants are appointed astro-detectives in-charge and asked to find the rings by browsing around the Solar System, which is scaled so as to fit the town historical centre or a pedestrian area, going from the Sun to Saturn or beyond, depending on the actual area at disposal. Great care must be taken allowing children playing only in a car-free area of the town. At the right scaled distances, the partecipants meet characters playing as the various planets. The kids can talk to them after solving a riddle, obtaining useful informations. A special characters play as a comet, timely going in and out of the inner solar system.

    2015-04-01

    Full Text Available The problems connected with the issue of service quality is an important aspect in the service industry, however it is difficult to measure. It may be quite difficult to estimate it unequivocally and objectively due to the fact that each service includes more or fewer materi-al elements. It is impossible to improve something that has not been measured and estimated before and one does not know whether it fulfils the requirements. Hotel gastronomy services are a kind of service that are partly materialized which makes the quality estimation easier. Nevertheless, one ought to remember that they are also shaped by non-material elements that influence the final quality estimation which seems to be problematic. The so-called Mystery Shopper Technique as a way of improving the quality of hotel gastronomy services is pre-sented in the article.

    A previously unremarkable star in the constellation Cygnus has, in the past year, become known as the most mysterious object in our Galaxy. Boyajian’s star exhibits puzzling episodes of sporadic, deep dimming discovered in photometry with the Kepler Mission. Proposed explanations have focused on its obscuration by colliding exoplanets, exocomets, and even intervention of alien intelligence. These hypotheses have considered only phenomena external to the star because the radiative flux missing in the dimmings was believed to exceed the star’s storage capacity. We point out that modeling of variations in solar luminosity indicates that convective stars can store the required fluxes. It also suggests explanations for (a) a reported time-profile asymmetry of the short, deep dimmings and (b) a slower, decadal scale dimming reported from archival and Kepler photometry. Our findings suggest a broader range of explanations of Boyajian’s star that may produce new insights into stellar magneto-convection.

    The large frieze of the "Villa of the Mysteries" at Pompeji is interpreted on the base of the psychology of C. G. Jung, especially of his student Erich Neumann. According to his psychological theories the frieze is depicting the development of the female principle to individuation, arranged with extraordinary artistic inspiration. Through the myth of Ariadne-Theseus-Dionysus the change of the woman, disappointed from the personal man and hero is shown. Through the experience of the transpersonal male principle in herself she is entering in a new level of conscience, the patriarchism, and so coming to the highest development, to the "Selbst". The experience of the male principle is made through Dionysus, a symbol of change in the theory of the "Archetypen" found by C. G. Jung.

    Pharmacy access to emergency contraception (EC) could involve men in pregnancy prevention. The objectives were to assess the availability and cost of EC. Male mystery shoppers visited 158 pharmacies in three neighborhoods in New York City. They asked for EC and its cost and noted weekend hours. Twenty-two (73.3%) of 30 pharmacies created barriers to get EC. The cost of EC was higher in the higher-socioeconomic status (SES) neighborhood (p<.001), and the higher-SES neighborhood pharmacies had a greater number of weekend hours (p<.001). Overall, males had a 20% probability of not being able to access EC. The national dialogue should include males. Copyright © 2014 Elsevier Inc. All rights reserved.

    2018-03-08

    In ancient hothouses lacking ice sheets, the origins of large, million-year (myr)-scale sea-level oscillations remain a mystery, challenging current models of sea-level change. To address this mystery, we develop a sedimentary noise model for sea-level changes that simultaneously estimates geologic time and sea level from astronomically forced marginal marine stratigraphy. The noise model involves two complementary approaches: dynamic noise after orbital tuning (DYNOT) and lag-1 autocorrelation coefficient (ρ 1 ). Noise modeling of Lower Triassic marine slope stratigraphy in South China reveal evidence for global sea-level variations in the Early Triassic hothouse that are anti-phased with continental water storage variations in the Germanic Basin. This supports the hypothesis that long-period (1-2 myr) astronomically forced water mass exchange between land and ocean reservoirs is a missing link for reconciling geological records and models for sea-level change during non-glacial periods.

  3. The Mysteries and Curiosities of Mars: A Tour of Unusual and Unexplained Terrains

    The large amount of data available from orbiting satellites around Mars has provided a wealth of information about the Martian surface and geological history. The published literature tends to focus on regions of Mars for which there are ready explanations; however, many regions of Mars remain mysterious. In this contribution, we present some of the strangest and least explained terrains on Mars: The Taffy Terrain: This complex terrain, consisting of swirling layers with variably sized bands, is present mostly at the bottom of Hellas Basin, but versions of it can also be found on the floor of Melas Chasma and in the Medusae Fossae Formation near Apollinaris Sulci. While little has been written about the taffy terrain, hypotheses include "glacial features" and salt domes. The taffy terrain bears some resemblance to submarine salt domes in the Gulf of Mexico, glacial deposits with mixed ash and ice in Iceland, or chalk formations in Egypt's White Desert. The Fishscale Terrain: At the northern edge of Lucus Planum, the friable Medusae Fossae Formation transitions into a chaos-like terrain with hundreds of mesas forming a pattern like the scales of a fish. While chaos terrains are mysterious in general, this morphologically fresh, near-equatorial chaos is especially unusual. Polygonal Ridges in Gordii Dorsum: Also a part of the Medusae Fossae Formation, the ridges in Gordii Dorsum represent a negative image of the fishscale terrain—a intricate lattice of slender black ridges. These are thought to form via the embayment of the fishscale terrain with lava and the subsequent erosion of the original mesas. Horseshoe Features: These geomorphological features look like inverted barchan dunes, but they are actually pits eroded into the surface of the Medusae Fossae Formation. Channels surrounding Elysium Mons: These channel systems are among the most complex on Mars, but they appear on a young Amazonian lava surface. The channels cut through topography, anastomose, and

    Full Text Available Being on a positive trend and addressing to a market that is less willing to compromise, the tourism industry develops a highly complex content, represented by various organizations and services, having as a main objective meeting the expectations of consumers of tourism services and reporting to the challenges of contemporary dynamics generated by the emergence of new information technologies. To respond effectively to these issues, tourism requires among other things a modern HR management. For travel agencies, human resources are the main asset of the company that serves to implement the entity's objectives. The most important qualities of the travel agent are polite attitude, promptness, sagacity and firmness. However, the ability to display with celerity their own capabilities - intellectual, psycho-motivational and persuasive - represents the quintessence of the travel agent profession. When we refer to these features, in the universal tourism language we talk about SAP concept: Speed, Accuracy, Politeness. Therefore, the major objective of this study aims to assess the employees of travel agencies from Suceava County in terms of SAP components using three different methods of qualitative research: Mystery Shopping, Mystery Calling and Mystery Emailing.

    From the author of "Celestial Sleuth" (2014), yet more mysteries in art, history, and literature are solved by calculating phases of the Moon, determining the positions of the planets and stars, and identifying celestial objects in paintings. In addition to helping to crack difficult cases, these studies spark our imagination and provide a better understanding of the skies. Weather archives, vintage maps, tides, historical letters and diaries, military records and the assistance of experts in related fields help with this work. For each historical event influenced by astronomy, there is a different kind of mystery to be solved. How did the changing tides affect an army's battle plans? How did the phases of the moon affect how an artist painted a landscape? Follow these exciting investigations with a master “celestial sleuth” as he tracks down the truth and helps unravel mysteries as far back as the Middle Ages and as recent as the iconic 1945 photograph of a kiss in Times Square on VJ Day.

    2013-01-01

    The Chinese mystery snail (Bellamya chinensis) is an aquatic invasive species found throughout the USA. Little is known about this species’ life history or ecology, and only one population estimate has been published, for Wild Plum Lake in southeast Nebraska. A recent die-off event occurred at this same reservoir and we present a mortality estimate for this B. chinensis population using a quadrat approach. Assuming uniform distribution throughout the newly-exposed lake bed (20,900 m2), we estimate 42,845 individuals died during this event, amounting to approximately 17% of the previously-estimated population size of 253,570. Assuming uniform distribution throughout all previously-reported available habitat (48,525 m2), we estimate 99,476 individuals died, comprising 39% of the previously-reported adult population. The die-off occurred during an extreme drought event, which was coincident with abnormally hot weather. However, the exact reason of the die-off is still unclear. More monitoring of the population dynamics of B. chinensis is necessary to further our understanding of this species’ ecology.

  9. Investigating the mysteries of groundwater in the Badain Jaran Desert, China

    Science.gov (United States)

    Wang, Xu-Sheng; Zhou, Yanyi

    2018-03-01

    The Badain Jaran Desert (BJD) in China is a desert with impressive sand dunes and a groundwater situation that has attracted numerous researchers. This paper gives an overview of the mysteries of groundwater in the BJD that are exhibited as five key problems identified in previous studies. These problems relate to the origin of the groundwater, the hydrological connection between the BJD and the Heihe River Basin (HRB), the infiltration recharge, the lake-groundwater interactions, and the features of stable isotope analyses. The existing controversial analyses and hypotheses have caused debate and have hindered effective water resources management in the region. In recent years, these problems have been partly addressed by additional surveys. It has been revealed that the Quaternary sandy sediments and Neogene-Cretaceous sandstones form a thick aquifer system in the BJD. Groundwater flow at the regional scale is dominated by a significant difference in water levels between the surrounding mountains and lowlands at the western and northern edges. Discharge of groundwater from the BJD to the downstream HRB occurs according to the regional flow. Seasonal fluctuations of the water level in lakes are less than 0.5 m due to the quasi-steady groundwater discharge. The magnitude of infiltration recharge is still highly uncertain because significant limitations existed in previous studies. The evaporation effect may be the key to interpreting the anomalous negative deuterium-excess in the BJD groundwater. Further investigations are expected to reveal the hydrogeological conditions in more detail.

  10. The mysterious age invariance of the planetary nebula luminosity function bright cut-off

    2018-05-01

    Planetary nebulae mark the end of the active life of 90% of all stars. They trace the transition from a red giant to a degenerate white dwarf. Stellar models1,2 predicted that only stars above approximately twice the solar mass could form a bright nebula. But the ubiquitous presence of bright planetary nebulae in old stellar populations, such as elliptical galaxies, contradicts this: such high-mass stars are not present in old systems. The planetary nebula luminosity function, and especially its bright cut-off, is almost invariant between young spiral galaxies, with high-mass stars, and old elliptical galaxies, with only low-mass stars. Here, we show that new evolutionary tracks of low-mass stars are capable of explaining in a simple manner this decades-old mystery. The agreement between the observed luminosity function and computed stellar evolution validates the latest theoretical modelling. With these models, the planetary nebula luminosity function provides a powerful diagnostic to derive star formation histories of intermediate-age stars. The new models predict that the Sun at the end of its life will also form a planetary nebula, but it will be faint.

    There are still many questions that remain about the Moon. From concentric craters to lunar swirls, water vapor and lunar reverberations on impact, Foster collects it all for a fascinating tour that will illuminate the backyard observer's understanding of this easily viewed, yet also imperfectly understood, celestial object. Data from Apollo and a flotilla of unmanned Moon orbiters, crashers, and landers have all contributed to our understanding of the Moon, but these mysteries linger despite decades of research. When Project Apollo brought back lunar rocks and soil samples, it opened a new chapter of understanding Earth's lone natural satellite, a process that continues to this day, as old results are revisited and new techniques are used on existing samples. Topics such as the origin, evolution, structure and composition of the Moon, however, are still under debate. Lunar research is still an active field of study. New technologies make it possible to continue to learn. But even so, the Moon continues to h...

    We use near-infrared grism spectroscopy from the Hubble Space Telescope to examine the strength of [Ne III] λ3869 relative to Hβ, [O II] λ3727, and [O III] λ5007 in 236 low-mass (7.5 ≲ log (M {sub *}/M {sub ☉}) ≲ 10.5) star-forming galaxies in the redshift range 1.90 < z < 2.35. By stacking the data by stellar mass, we show that the [Ne III]/[O II] ratios of the z ∼ 2 universe are marginally higher than those seen in a comparable set of local Sloan Digital Sky Survey galaxies, and that [Ne III]/[O III] is enhanced by ∼0.2 dex. We consider the possible explanations for this ∼4σ result, including higher oxygen depletion out of the gas phase, denser H II regions, higher production of {sup 22}Ne via Wolf-Rayet stars, and the existence of a larger population of X-ray obscured active galactic nuclei at z ∼ 2 compared to z ∼ 0. None of these simple scenarios, alone, are favored to explain the observed line ratios. We conclude by suggesting several avenues of future observations to further explore the mystery of enhanced [Ne III] emission.

  14. Unraveling the mystery of music: music as an evolved group process.

    2013-11-01

    As prominently highlighted by Charles Darwin, music is one of the most mysterious aspects of human nature. Despite its ubiquitous presence across cultures and throughout recorded history, the reason humans respond emotionally to music remains unknown. Although many scientists and philosophers have offered hypotheses, there is little direct empirical evidence for any perspective. Here we address this issue, providing data which support the idea that music evolved in service of group living. Using 7 studies, we demonstrate that people's emotional responses to music are intricately tied to the other core social phenomena that bind us together into groups. In sum, this work establishes human musicality as a special form of social cognition and provides the first direct support for the hypothesis that music evolved as a tool of social living. In addition, the findings provide a reason for the intense psychological pull of music in modern life, suggesting that the pleasure we derive from listening to music results from its innate connection to the basic social drives that create our interconnected world.

    It is generally accepted in plant-microbe interactions research that disease is the exception rather than a common outcome of pathogen attack. However, in nature, plants with symptoms that signify colonization by obligate biotrophic powdery mildew fungi are omnipresent. The pervasiveness of the disease and the fact that many economically important plants are prone to infection by powdery mildew fungi drives research on this interaction. The competence of powdery mildew fungi to establish and maintain true biotrophic relationships renders the interaction a paramount example of a pathogenic plant-microbe biotrophy. However, molecular details underlying the interaction are in many respects still a mystery. Since its introduction in 1990, the Arabidopsis-powdery mildew pathosystem has become a popular model to study molecular processes governing powdery mildew infection. Due to the many advantages that the host Arabidopsis offers in terms of molecular and genetic tools this pathosystem has great capacity to answer some of the questions of how biotrophic pathogens overcome plant defense and establish a persistent interaction that nourishes the invader while in parallel maintaining viability of the plant host.

  16. Unravelling the Mystery of the Atomic Nucleus A Sixty Year Journey 1896 — 1956

    CERN Document Server

    Fernandez, Bernard

    2013-01-01

    Unravelling the Mystery of the Atomic Nucleus tells the story of how, in the span of barely sixty years, we made a transition from the belief that matter was composed of indivisible atoms, to the discovery that in the heart of each atom lies a nucleus which is ten thousand times smaller than the atom, which nonetheless carries almost all its mass, and the transformations of which involve energies that could never be reached by chemical reactions. It was not a smooth transition. The nature of nuclei, their properties, the physical laws which govern their behaviour, and the possibility of controlling to some extent their transformations, were discovered in discontinuous steps, following paths which occasionally led to errors which in turn were corrected by further experimental discoveries. The story begins in 1896 when radioactivity was unexpectedly discovered and continues up to the nineteen-sixties. The authors describe the spectacular progress made by physics during that time, which not only revealed a new f...

    The amorphous blue phase III of cholesteric liquid crystals, also known as the "blue fog," are among the rising stars in materials science that can potentially be used to develop next-generation displays with the ability to compete toe-to-toe with disruptive technologies like organic light-emitting diodes. The structure and properties of the practically unobservable blue phase III have eluded scientists for more than a century since it was discovered. This progress report reviews the developments in this field from both fundamental and applied research perspectives. The first part of this progress report gives an overview of the 130-years-long scientific tour-de-force that very recently resulted in the revelation of the mysterious structure of blue phase III. The second part reviews progress made in the past decade in developing electrooptical, optical, and photonic devices based on blue phase III. The strong and weak aspects of the development of these devices are underlined and criticized, respectively. The third- and-final part proposes ideas for further improvement in blue phase III technology to make it feasible for commercialization and widespread use. © 2017 WILEY-VCH Verlag GmbH & Co.

  18. Joseph Carpue's file drawer experiment – A murder mystery from 1801

    M. Felix Freshwater

    2015-12-01

    Full Text Available Today unpublished or “file drawer” experiments are the impetus for trial registration and reporting of all results. In 1801, Joseph Carpue, the father of modern plastic surgery, did a file drawer experiment for Benjamin West, who was President of the Royal Academy of Arts. George III had commissioned West to create the largest stained glass window ever created whose theme, the Crucifixion, was based upon Michelangelo's drawing. Subsequently, West suffered a series of political, professional and economic setbacks. In the summer of 1801, West's project was delayed. By the fall, West hoped that independent scientific confirmation of his design could salvage the project. West approached Carpue who obtained a murderer's fresh corpse that he crucified and documented the results with plaster casts created by sculptor Thomas Banks. Carpue's experiment showed that West's window design wrongly depicted the Crucifixion because West had posed the hands and shoulders incorrectly. West died in 1820 without ever being associated with Carpue's experiment. Carpue's obituary in The Lancet in 1846 contained Carpue's handwritten note that described the experiment but not West's Royal commission. As no records or publications associate the cast with West project, this can be considered to be a file drawer experiment. After 1801, West made further drawings of the Crucifixion that showed the figures in the same position as the cast. Nineteenth century auction catalogues suggest that West made a corrected Crucifixion painting, but its current location remains a mystery.

  19. Origin of the mysterious Yin-Shang bronzes in China indicated by lead isotopes.

    Fine Yin-Shang bronzes containing lead with puzzlingly highly radiogenic isotopic compositions appeared suddenly in the alluvial plain of the Yellow River around 1400 BC. The Tongkuangyu copper deposit in central China is known to have lead isotopic compositions even more radiogenic and scattered than those of the Yin-Shang bronzes. Most of the Yin-Shang bronzes are tin-copper alloys with high lead contents. The low lead and tin concentrations, together with the less radiogenic lead isotopes of bronzes in an ancient smelting site nearby, however, exclude Tongkuangyu as the sole supplier of the Yin-Shang bronzes. Interestingly, tin ingots/prills and bronzes found in Africa also have highly radiogenic lead isotopes, but it remains mysterious as to how such African bronzes may have been transported to China. Nevertheless, these African bronzes are the only bronzes outside China so far reported that have lead isotopes similar to those of the Yin-Shang bronzes. All these radiogenic lead isotopes plot along ~2.0-2.5 Ga isochron lines, implying that deposits around Archean cratons are the most likely candidates for the sources. African cratons along the Nile and even micro-cratons in the Sahara desert may have similar lead signatures. These places were probably accessible by ancient civilizations, and thus are the most favorable suppliers of the bronzes.

  20. Mysteries of Mind and Matter in the Perspective of Colin McGinn’s Philosophy

    Directory of Open Access Journals (Sweden)

    Dmytro Sepetyi

    2016-02-01

    Full Text Available The paper discusses the approach to the mind-body problem that was developed by Colin McGinn and is known as “mysterianism”. The basic thesis of this approach, which McGinn opposes to both materialism and dualism, is that consciousness and its relationship to physical reality is an inscrutable mystery that cannot be get over in principle, because of insurmountable, constitutive limitations of human mind. In this paper, the critical analysis of McGinn’s approach is given. It is pointed out that McGinn’s thesis of the inscrutablility of the mind-body relationship is based on the ungrounded idea that a mediating substance is necessary. An argument is made that the mind-body relationship is better understood as interaction that is mediated only by natural psychophysical laws. McGinn’s hypothesis of the origin of physical space in a non-spatial reality that has the same nature as consciousness is explained in the context of different interpretations of the Big Bang theo- ry. It is argued that McGinn’s hypothesis does not provide a solution to the problem of the origin of human consciousness, because consciousness belongs to mental individuals whose emergence is just as unexplainable by the hypothesis of non-spatial reality as it is by physical processes.

  1. Brightness Variations of Sun-like Stars: The Mystery Deepens - Astronomers facing Socratic "ignorance"

    Science.gov (United States)

    2009-12-01

    An extensive study made with ESO's Very Large Telescope deepens a long-standing mystery in the study of stars similar to the Sun. Unusual year-long variations in the brightness of about one third of all Sun-like stars during the latter stages of their lives still remain unexplained. Over the past few decades, astronomers have offered many possible explanations, but the new, painstaking observations contradict them all and only deepen the mystery. The search for a suitable interpretation is on. "Astronomers are left in the dark, and for once, we do not enjoy it," says Christine Nicholls from Mount Stromlo Observatory, Australia, lead author of a paper reporting the study. "We have obtained the most comprehensive set of observations to date for this class of Sun-like stars, and they clearly show that all the possible explanations for their unusual behaviour just fail." The mystery investigated by the team dates back to the 1930s and affects about a third of Sun-like stars in our Milky Way and other galaxies. All stars with masses similar to our Sun become, towards the end of their lives, red, cool and extremely large, just before retiring as white dwarfs. Also known as red giants, these elderly stars exhibit very strong periodic variations in their luminosity over timescales up to a couple of years. "Such variations are thought to be caused by what we call 'stellar pulsations'," says Nicholls. "Roughly speaking, the giant star swells and shrinks, becoming brighter and dimmer in a regular pattern. However, one third of these stars show an unexplained additional periodic variation, on even longer timescales - up to five years." In order to find out the origin of this secondary feature, the astronomers monitored 58 stars in our galactic neighbour, the Large Magellanic Cloud, over two and a half years. They acquired spectra using the high resolution FLAMES/GIRAFFE spectrograph on ESO's Very Large Telescope and combined them with images from other telescopes [1

    The exoskeleton of gastropods provides a convenient surface for carrying marks, and i the interest of improving future marking methods our laboratory assessed the performance of an enamel paint. The endurance of the paint was also compared to other marking methods assessed in the past. We marked the shells of 30 adult Chinese mystery snails Bellamya chinensis and held them in an aquarium for 181 days. We observed no complete degradation of any enamel-paint mark during the 181 days. The enamel-paint mark was superior to a nai;-polish mark, which lasted a median of 100 days. Enamel-paint marks also have a lower rate of loss (0.00 month-1 181 days) than plastic bee tags (0.01 month-1, 57 days), gouache paint (0.07 month-1, 18.5 days), or car body paint from studies found in scientific literature. Legibility of enamel-paint marks had a median lifetime of 102 days. The use of enamel paint on the shells of gastropods is a viable option for studies lasting up to 6 months. Furthermore, visits to capture-mark-recapture site 1 year after application of enamel-paint marks on B. chinesnis shells produced several individuals on which the enamel paint was still visible, although further testing is required to clarify durability over longer periods.

    Napoleon Bonaparte (1769 to 1821) is one of the most studied historical figures in European history. Not surprisingly, amongst the many mysteries still surrounding his person is the cause of his death, and particularly the suspicion that he was poisoned, continue to intrigue medical historians. After the defeat of the Napoleonic Army at the battle of Waterloo in 1815, Napoleon was exiled to the small island of Saint Helena in the South Atlantic, where he died 6 years later. Although his personal physician, Dr François Carlo Antommarchi, stated in his autopsy report that stomach cancer was the cause of death, this diagnosis was challenged in 1961 by the finding of an elevated arsenic concentration in one of Napoleon's hair samples. At that time it was suggested that Napoleon had been poisoned by one of his companions in exile who was allegedly supported by the British Government. Since then Napoleon's cause of death continues to be a topic of debate. The aim of this review is to use a multidisciplinary approach to provide a systematic and critical assessment of Napoleon's cause of death.

    2010-12-01

    UK women increasingly prefer to attend a pharmacy for emergency contraception (EC) rather than a doctor. Most women who use EC do not conceive and remain at risk of pregnancy unless they start regular contraception. We undertook a study to evaluate the quality of service provision in community pharmacies in Lothian, Scotland, and to determine what advice is given about contraception after EC use. Mystery shopper study. EC was unobtainable from 5/40 pharmacies (12.5%), refused because of "contraindications" in 7 (17.5%) and offered in 28 (70%). Most pharmacists appeared nonjudgemental, over 75% asked appropriate questions about eligibility, and over 90% gave appropriate advice about use. EC was universally refused beyond 72 h after sex but universally provided when the date of the last menstrual period was uncertain. Ongoing contraception after EC use was discussed in only 32.5% of all pharmacies and only 43% of those issuing EC. The quality of consultations for EC in pharmacies is generally good but only a minority discuss ongoing contraception after EC use. The implications for contraceptive use and unintended pregnancy rates are worrying. Copyright © 2010 Elsevier Inc. All rights reserved.

It is a cause of chronic hepatitis in immunosuppressed patients. It has human to human transmission through blood and mantains high seroprevalence in blood donors. HEV has also been found to occur more frequently in the West in those without a history of travel to endemic countries. It has varied extrahepatic manifestations and has multiple non-human reservoirs including pigs and rats. Considering these recent discoveries, it appears odd that HEV is not sought more frequently when working up acute and chronic hepatitis patients. The disease is particularly severe among pregnant women and has a high attack rate in young adults. What adds to its ambiguity is the absence of a well-established diagnostic criteria for its detection and that there is no specific antiviral drug for hepatitis E, except for isolated cases where ribavirin or pegylated interferon alpha has been used with occasional success. This review paper discusses the recent advances in the knowledge of the virus itself, its epidemiology, diagnostic approach and prevention, and the treatment options available.

    Background A Noh mask worn by expert actors when performing on a Japanese traditional Noh drama is suggested to convey countless different facial expressions according to different angles of head/body orientation. The present study addressed the question of how different facial parts of a Noh mask, including the eyebrows, the eyes, and the mouth, may contribute to different emotional expressions. Both experimental situations of active creation and passive recognition of emotional facial expressions were introduced. Methodology/Principal Findings In Experiment 1, participants either created happy or sad facial expressions, or imitated a face that looked up or down, by actively changing each facial part of a Noh mask image presented on a computer screen. For an upward tilted mask, the eyebrows and the mouth shared common features with sad expressions, whereas the eyes with happy expressions. This contingency tended to be reversed for a downward tilted mask. Experiment 2 further examined which facial parts of a Noh mask are crucial in determining emotional expressions. Participants were exposed to the synthesized Noh mask images with different facial parts expressing different emotions. Results clearly revealed that participants primarily used the shape of the mouth in judging emotions. The facial images having the mouth of an upward/downward tilted Noh mask strongly tended to be evaluated as sad/happy, respectively. Conclusions/Significance The results suggest that Noh masks express chimeric emotional patterns, with different facial parts conveying different emotions This appears consistent with the principles of Noh which highly appreciate subtle and composite emotional expressions, as well as with the mysterious facial expressions observed in Western art. It was further demonstrated that the mouth serves as a diagnostic feature in characterizing the emotional expressions. This indicates the superiority of biologically-driven factors over the traditionally

    Modern Astrophysics is one of the most data intensive research fields in the world and is driving many of the required innovations in the "big data" space. Foremost in astronomy in terms of data generation is radio astronomy, and in the last decade an increase in global interest and investment in the field had led to a large number of new or upgraded facilities which are each currently generating petabytes of data per annum. The peak of this so-called 'radio renaissance' will be the Square Kilometre Array (SKA) - a global observatory designed to uncover the mysteries of the Universe. The SKA will create the highest resolution, fastest frame rate movie of the evolving Universe ever and in doing so will generate 160 terrabytes of data a second, or close to 5 zettabytes of data per annum. Furthermore, due to the extreme faintness of extraterrestrial radio signals, the telescope elements for the SKA must be located in radio quite parts of the world with very low population density. Thus the project aims to build the most data intensive scientific experiment ever, in some of the most remote places on Earth. Generating and serving scientific data products of this scale to a global community of researchers from remote locations is just the first of the "big data" challenges the project faces. Coordination of a global network of tiered data resources will be required along with software tools to exploit the vast sea of results generated. In fact, to fully realize the enormous scientific potential of this project, we will need not only better data distribution and coordination mechanisms, but also improved algorithms, artificial intelligence and ontologies to extract knowledge in an automated way at a scale not yet attempted in science. In this keynote I will present an overview of the SKA project, outline the "big data" challenges the project faces and discuss some of the approaches we are taking to tame the astronomical data deluge we face.

    Recent programmatic and research efforts on addressing gaps in health systems of low-income countries increasingly see task shifting, i.e. the provision of healthcare by non-medically trained personnel, as a possible solution to increase the availability of specific services and commodities. In Kinshasa, private-sector pharmacies are the primary and preferred provider of family planning (FP) methods, and thus constitute a potential resource for expanding access to specific contraceptives. The objective of this study is to explore selected pharmacies' readiness to serve women seeking emergency contraception (EC). This study used a mystery client (MC) methodology to visit 73 pharmacies in Kinshasa, Democratic Republic of Congo (DRC). Trained interviewers posed as novice EC users and asked specific questions to evaluate the pharmacy staff's technical knowledge of EC and their attitudes towards EC clients. The results of the MC visit were recorded immediately after the MC left the pharmacy. Findings indicate that more than two-thirds of EC providers were knowledgeable about EC dosage, timeframe, and side effects, and 90% were deemed helpful towards novice EC users. Rare but glaring misconceptions about EC timeframe (20% of providers) and long-term side effects (4% of providers), as well as frequent stock-out (22%) and cost issues highlight priorities for programmatic improvements. As new service delivery strategies are explored to complement the uneven network of health structures in DRC, this study suggests that, given proper training and integration in FP programming, private-sector pharmacies have the potential to meet specific contraceptive needs for women living in Kinshasa. Private pharmacies included in study sample in Kinshasa (DRC) have adequate family planning (FP) service skills to provide clients with emergency contraceptive pills. These higher-end outlets constitute an opportunity for expanding access to FP, although, under total market approaches, a more

    The next major earthquake to strike the ~7 million residents of the San Francisco Bay Area will most likely result from rupture of the Hayward or Rodgers Creek faults. Until now, the relationship between these two faults beneath San Pablo Bay has been a mystery. Detailed subsurface imaging provides definitive evidence of active faulting along the Hayward fault as it traverses San Pablo Bay and bends ~10° to the right toward the Rodgers Creek fault. Integrated geophysical interpretation and kinematic modeling show that the Hayward and Rodgers Creek faults are directly connected at the surface-a geometric relationship that has significant implications for earthquake dynamics and seismic hazard. A direct link enables simultaneous rupture of the Hayward and Rodgers Creek faults, a scenario that could result in a major earthquake ( M = 7.4) that would cause extensive damage and loss of life with global economic impact.

  15. Potential Remedies for the High Synchrotron-Radiation-Induced Heat Load for Future Highest-Energy-Proton Circular Colliders

    CERN Document Server

    AUTHOR|(CDS)2084568; Baglin, Vincent; Schaefers, Franz

    2015-01-01

    We propose a new method for handling the high synchrotron radiation (SR) induced heat load of future circular hadron colliders (like FCC-hh). FCC-hh are dominated by the production of SR, which causes a significant heat load on the accelerator walls. Removal of such a heat load in the cold part of the machine, as done in the Large Hadron Collider, will require more than 100 MW of electrical power and a major cooling system. We studied a totally different approach, identifying an accelerator beam screen whose illuminated surface is able to forward reflect most of the photons impinging onto it. Such a reflecting beam screen will transport a significant part of this heat load outside the cold dipoles. Then, in room temperature sections, it could be more efficiently dissipated. Here we will analyze the proposed solution and address its full compatibility with all other aspects an accelerator beam screen must fulfill to keep under control beam instabilities as caused by electron cloud formation, impedance, dynamic...

    The 4m Daniel K. Inouye Solar Telescope (DKIST) currently under construction on Haleakala, Maui will be the world’s largest solar telescope. Designed to meet the needs of critical high resolution and high sensitivity spectral and polarimetric observations of the sun, this facility will perform key observations of our nearest star that matters most to humankind. DKIST’s superb resolution and sensitivity will enable astronomers to address many of the fundamental problems in solar and stellar astrophysics, including the origin of stellar magnetism, the mechanisms of coronal heating and drivers of the solar wind, flares, coronal mass ejections and variability in solar and stellar output. DKIST will also address basic research aspects of Space Weather and help improve predictive capabilities. In combination with synoptic observations and theoretical modeling DKIST will unravel the many remaining mysteries of the Sun.The construction of DKIST is progressing on schedule with 80% of the facility complete. Operations are scheduled to begin early 2020. DKIST will replace the NSO facilities on Kitt Peak and Sac Peak with a national facility with worldwide unique capabilities. The design allows DKIST to operate as a coronagraph. Taking advantage of its large aperture and infrared polarimeters DKIST will be capable to routinely measure the currently illusive coronal magnetic fields. The state-of-the-art adaptive optics system provides diffraction limited imaging and the ability to resolve features approximately 20 km on the Sun. Achieving this resolution is critical for the ability to observe magnetic structures at their intrinsic, fundamental scales. Five instruments will be available at the start of operations, four of which will provide highly sensitive measurements of solar magnetic fields throughout the solar atmosphere – from the photosphere to the corona. The data from these instruments will be distributed to the world wide community via the NSO/DKIST data center

  17. Specular Reflections from Titan's Equatorial Region: Solving the Decade Old Mystery

    Hofgartner, J. D.; Campbell, D. B.; Hayes, A.; Lunine, J. I.

    2014-12-01

    Specular reflections from Titan's equatorial region have been detected using the Arecibo Observatory's (AO) 13 cm wavelength radar system (Campbell et al., 2003, Science, 302, 431). Fitting the echo spectra to radar scattering models indicated that they originated from smooth surfaces with root-mean-square slopes of only a few degrees; on this basis they were interpreted as evidence for liquid surfaces. The Cassini Saturn Orbiter however has detected stable surface liquids only in the polar regions and not in the southern tropical regions covered by the AO tracks. High resolution Cassini imagery that overlaps with the AO tracks between the years 2000 and 2008 does not suggest the presence of hydrocarbon liquids and exhibits no apparent correlation with the 13 cm scattering (Black et al., 2011, Icarus, 212, 300). In this work in progress, we explore alternative explanations for the origin of these low latitude specular reflections and attempt to resolve this now decade old mystery. In particular, we use the accumulating Cassini RADAR altimetry coverage to compare the nadir backscatter at 2.2 cm to that at 13 cm. This nadir-to-nadir comparison allows us to constrain whether the southern tropical regions are also smooth and specular at smaller scales. We also plan to constrain whether these regions are representative of Titan in general or have unusually smooth surface by utilizing the complete Cassini altimetry dataset that includes observations dispersed around the globe. Distant Cassini RADAR scatterometry-mode observations suggest that Titan exhibits a greater nadir backscatter than expected from traditional quasi-specular plus diffuse backscattering models (L. Wye, 2011, Ph.D. Thesis, Stanford University), hinting that unusually specular radar echoes may be the general behavior for Titan. Additionally, we employ the long baseline of Cassini observations over nearly half a Titan year, to constrain the possible temporal evolution in backscatter that was suggested

  18. Profile: Mistress of the mysteries of Russian oil and Faberge egg

    Lorenz, A.

    2002-10-07

    A book, entitled 'The Russian oil economy', co-authored by Jennifer Considine and William A. Kerr, is reviewed. This singularly instructive book, based on Considine's doctoral dissertation and published by Edward Elger Publishing, Cheltenham, is intended as essential reading for anyone planning to invest in the Russian petroleum industry. The book is also an example of how will-power and discipline will overcome personal tragedy. It is based on a thorough study of how Russia's economy descended to its current decrepit state. The conclusion reached from that study is that the Russian petroleum industry has never been guided by market forces as they are understood in the West. Rather, the Russian industry has been shaped by historical forces and therefore cannot be approached from a market economy perspective. Accordingly, the reader is guided through the turbulent history of the Soviet era, focusing on economic policies affecting the petroleum industry, the forces that were brought to bear on the industry and that guided its development under each of the presidents and party chairmen, Stalin, Kruschev, Brezhnev, Yeltsin. The authors capture the ineptitude -- but also the drama and the fleeting moments of brilliance -- that characterize Russia's petroleum industry, and through painstaking analysis arrive at the conclusion that even today the Russian Federation is not a market economy, and may never become one. As a sideline to the main theme, but at the same time an integral part of the forces that shaped Considine's own personal development, runs the story of her difficult youth, the struggle to continue her studies while looking after her gravely ill mother and while trying also to be part of an investigation of the disappearance of a $3 million Faberge egg from her mother's home, allegedly stolen by a trusted friend. The mystery of the Faberge egg is still unresolved, but Considine completed her studies, the book has been

  19. An Attempt to Interpret the Concept of «Mystery» in Relation to the Divine Liturgy and Church Temple

    Artur Aleksiejuk

    2016-12-01

    Full Text Available This article is an attempt to look at the most important events in the history of salvation from a liturgical perspective. This reflection begins with an etymological and theological interpretation of the concept of «anamnesis» (ανάμνησις and «mystery» (μυστήρὶα, which have fundamental significance in the liturgical practice of the Orthodox Church. This reflection also serves as an occasion to emphasise the necessity of a continual search for answers to questions which have always had crucial importance for the life and experience of the Church as a human-divine community of the faithful: for Christians, what is the liturgical commemoration of the life and death of the Saviour Jesus Christ, from His Incarnation to Ascension into Heaven to be seated at the Right Hand of the Father? Although the liturgical gift of commemoration is a mystery, it takes place in the Temple Church. This is therefore a visible sign of the invisible, deifying and saving grace of the Triune God, which loves mankind and the world which He created and longs to be “all in all”.

  20. Linking high-energy cosmic particles by black-hole jets embedded in large-scale structures

    Fang, Ke; Murase, Kohta

    2018-04-01

    The origin of ultrahigh-energy cosmic rays (UHECRs) is a half-century-old enigma1. The mystery has been deepened by an intriguing coincidence: over ten orders of magnitude in energy, the energy generation rates of UHECRs, PeV neutrinos and isotropic sub-TeV γ-rays are comparable, which hints at a grand unified picture2. Here we report that powerful black hole jets in aggregates of galaxies can supply the common origin for all of these phenomena. Once accelerated by a jet, low-energy cosmic rays confined in the radio lobe are adiabatically cooled; higher-energy cosmic rays leaving the source interact with the magnetized cluster environment and produce neutrinos and γ-rays; the highest-energy particles escape from the host cluster and contribute to the observed cosmic rays above 100 PeV. The model is consistent with the spectrum, composition and isotropy of the observed UHECRs, and also explains the IceCube neutrinos and the non-blazar component of the Fermi γ-ray background, assuming a reasonable energy output from black hole jets in clusters.

  2. Young Star Cluster Found Aglow With Mysterious X-Ray Cloud

    Science.gov (United States)

    2002-12-01

    A mysterious cloud of high-energy electrons enveloping a young cluster of stars has been discovered by astronomers using NASA's Chandra X-ray Observatory. These extremely high-energy particles could cause dramatic changes in the chemistry of the disks that will eventually form planets around stars in the cluster. Known as RCW 38, the star cluster covers a region about 5 light years across. It contains thousands of stars formed less than a million years ago and appears to be forming new stars even today. The crowded environment of a star cluster is thought to be conducive to the production of hot gas, but not high-energy particles. Such particles are typically produced by exploding stars, or in the strong magnetic fields around neutron stars or black holes, none of which is evident in RCW 38. "The RCW 38 observation doesn't agree with the conventional picture," said Scott Wolk of the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA, lead author of an Astrophysical Journal Letters paper describing the Chandra observation. "The data show that somehow extremely high-energy electrons are being produced there, although it is not clear how." RCW 38 RCW 38 X-ray, Radio, Infrared Composite Electrons accelerated to energies of trillions of volts are required to account for the observed X-ray spectrum of the gas cloud surrounding the ensemble of stars, which shows an excess of high-energy X-rays. As these electrons move in the magnetic field that threads the cluster, they produce X-rays. One possible origin for the high-energy electrons is a previously undetected supernova that occurred in the cluster. Although direct evidence for the supernova could have faded away thousands of years ago, a shock wave or a rapidly rotating neutron star produced by the outburst could be acting in concert with stellar winds to produce the high-energy electrons. "Regardless of the origin of the energetic electrons," said Wolk, "their presence would change the chemistry of proto

  4. Can increases in the cigarette tax rate be linked to cigarette retail prices? Solving mysteries related to the cigarette pricing mechanism in China.

    2012-11-01

    To explain China's cigarette pricing mechanism and the role of the Chinese State Tobacco Monopoly Administration (STMA) on cigarette pricing and taxation. Published government tobacco tax documentation and statistics published by the Chinese STMA are used to analyse the interrelations among industry profits, taxes and retail price of cigarettes in China. The 2009 excise tax increase on cigarettes in China has not translated into higher retail prices because the Chinese STMA used its policy authority to ensure that retail cigarette prices did not change. The government tax increase is being collected at both the producer and wholesale levels. As a result, the 2009 excise tax increase in China has resulted in higher tax revenue for the government and lower profits for the tobacco industry, with no increase in the retail price of cigarettes for consumers. Numerous studies have found that taxation is one of the most effective policy instruments for tobacco control. However, these findings come from countries that have market economies where market forces determine prices and influence how cigarette taxes are passed to the consumers in retail prices. China's tobacco industry is not a market economy; therefore, non-market forces and the current Chinese tobacco monopoly system determine cigarette prices. The result is that tax increases do not necessarily get passed on to the retail price.

    Nonnative invasive mollusks degrade aquatic ecosystems and induce economic losses worldwide. Extended air exposure through water body drawdown is one management action used for control. In North America, the Chinese mystery snail (Bellamya chinensis) is an invasive aquatic snail with an expanding range, but eradication methods for this species are not well documented. We assessed the ability of B. chinensis to survive different durations of air exposure, and observed behavioral responses prior to, during, and following desiccation events. Individual B. chinensis specimens survived air exposure in a laboratory setting for > 9 weeks, and survivorship was greater among adults than juveniles. Several B. chinensis specimens responded to desiccation by sealing their opercula and/or burrowing in mud substrate. Our results indicate that drawdowns alone may not be an effective means of eliminating B. chinensis. This study lays the groundwork for future management research that may determine the effectiveness of drawdowns when combined with factors such as extreme temperatures, predation, or molluscicides.

    PIXE/PIGE have been utilized extensively in the search for gold and volcanic hosted massive sulphide deposits, using rock powders from relatively fresh rock. The present study uses regolith samples, from which weathering products (oxides, hydroxides, carbonates, sulphates and clay) have been removed by sequential treatment with aqua regia and sulphuric acid. The samples come from the Mystery Zone, Mt Percy, Kalgoorlie, comprising both mineralized and barren samples. The acid insoluble residue consist essentially of quartz with minor sericite. The PlXE/PIGE data from the acid insoluble residue shows that the geochemical character of W, Al, K, Ca, V, Ga, Rb, Rb/K and Rb/Al could correctly define the location of underlying mineralization at depth. The ratio of Ti/Zr remained relatively constant in different geological units and can be used to distinguish lithologies. (authors)

    Science.gov (United States)

    Clancy, R. T.

    1986-01-01

    Visible limb radiances measured by the Solar Mesosphere Explorer (SME) are used to obtain volume scattering ratios for aerosol loading in the 30-55 km altitude range of the stratosphere. Global maps of these ratios are presented for the period January 1982 to August 1984. Significant aerosol scattering from the 'mystery cloud' and El Chichon aerosol layers are found above 30 km. A timescale of approximately 2 months between the appearance of the aerosol at 30.5 km and at 37.5 km is consistent with vertical transport of aerosol or vapor by eddy diffusion above 30 km. An anticorrelation exists between aerosol scattering and stratospheric temperatures. Periods of lower stratospheric temperatures may account for the formation of aerosol between 40 and 55 km altitude.

  12. Stutterheim’s enigma: The mystery of his mapping of the Majapahit kraton at Trowulan in 1941

    Full Text Available For over a century archaeologists have been trying to unravel the mystery of the location of the fourteenth-century kraton (palace of the rulers of the Majapahit kingdom which held power in Java from the thirteenth to the sixteenth century. It has been long known that the royal city and its palace was located at Trowulan about 50 kilometres southwest of Surabaya, the present-day capital of East Java. Today, unfortunately, all that remains of its former glory are isolated piles of broken bricks and an archaeologically mutilated landscape littered with craters dug by colonial-era asset strippers and treasure hunters. Knowledge of its exact position seemed to have vanished. In 1365 AD, however, the Javanese author Prapañca, had described the Majapahit capital and its royal palace in an extant Old Javanese text, called the N?garakr?t?gama or De?awarn?ana. Based upon this description, several scholars published reconstructions of the lay-out of the kraton of Majapahit, but none of them have been able to offer an identification of its exact location. In 1941, however, the then Head of the Netherlands Indies Archaeological Service (Oudheidkundige Dienst, W.F. Stutterheim, made a detailed reconstruction of the kraton of Majapahit, which the present authors are convinced correctly identified its precise location. The mystery is that Stutterheim himself did not reveal that location. This article sheds new light on the accuracy of Stutterheim’s reconstruction and his seemingly intentional obfuscation of the site identifications in Prapañca’s monumental work.

    To explore the supply of emergency contraception (EC) from Australian community pharmacies after the introduction of ulipristal acetate (UPA) and to explore pharmacists' knowledge, decision-making, attitudes and beliefs surrounding supplying EC. A mixed-methods approach of mystery shopping with structured interview was employed. From August to November 2017, 20 pharmacy students mystery-shopped 10 community pharmacies in metropolitan Sydney, Australia, requesting "the morning after pill." Each pharmacy was visited five times with varying scenarios. Structured interviews were conducted immediately postvisit. Visit data were analyzed descriptively and comparatively. Interviews were transcribed verbatim and categorically analyzed. Of 50 planned visits, 43 were analyzed. EC was supplied in 38 requests by pharmacists (54% male). Levonorgestrel (LNG) was more frequently supplied than UPA (74% vs. 26%). UPA was only supplied when intercourse occurred >72 h prior. Directions for use were provided in 35 supplies. No difference in questioning or counseling was found based on sex of requester. Female pharmacists provided more counseling points (MED=4 [IQR=4-5] vs. MED=3 [IQR=0-4]; p<.01). Two pharmacists asked all guideline questions, and no pharmacist provided all guideline counseling points. Interviews elicited supply guidelines, regulatory and clinical knowledge, financial considerations, privacy and stock availability as factors influencing EC supply. EC was supplied in accordance with local legislation in all instances, with the majority supplied within the licensed timeframe for each EC formulation. LNG was supplied more frequently than UPA. UPA was only supplied in the 72-120-h timeframe. Clinical and regulatory knowledge, availability and cost to consumer were identified as factors influencing supply. This study found that despite the introduction of ulipristal acetate to the Australian market, it is not frequently supplied. Interviews identified the need for

  14. Mystery of Foil Air Bearings for Oil-free Turbomachinery Unlocked: Load Capacity Rule-of-thumb Allows Simple Estimation of Performance

    2002-01-01

    The Oil-Free Turbomachinery team at the NASA Glenn Research Center has unlocked one of the mysteries surrounding foil air bearing performance. Foil air bearings are self-acting hydrodynamic bearings that use ambient air, or any fluid, as their lubricant. In operation, the motion of the shaft's surface drags fluid into the bearing by viscous action, creating a pressurized lubricant film. This lubricating film separates the stationary foil bearing surface from the moving shaft and supports load. Foil bearings have been around for decades and are widely employed in the air cycle machines used for cabin pressurization and cooling aboard commercial jetliners. The Oil-Free Turbomachinery team is fostering the maturation of this technology for integration into advanced Oil-Free aircraft engines. Elimination of the engine oil system can significantly reduce weight and cost and could enable revolutionary new engine designs. Foil bearings, however, have complex elastic support structures (spring packs) that make the prediction of bearing performance, such as load capacity, difficult if not impossible. Researchers at Glenn recently found a link between foil bearing design and load capacity performance. The results have led to a simple rule-of-thumb that relates a bearing's size, speed, and design to its load capacity. Early simple designs (Generation I) had simple elastic (spring) support elements, and performance was limited. More advanced bearings (Generation III) with elastic supports, in which the stiffness is varied locally to optimize gas film pressures, exhibit load capacities that are more than double those of the best previous designs. This is shown graphically in the figure. These more advanced bearings have enabled industry to introduce commercial Oil-Free gas-turbine-based electrical generators and are allowing the aeropropulsion industry to incorporate the technology into aircraft engines. The rule-of-thumb enables engine and bearing designers to easily size and

    While taking a giant leap towards solving one of the greatest mysteries of X-ray astronomy, NASA's Chandra X-ray Observatory also may have revealed the most distant objects ever seen in the universe and discovered two puzzling new types of cosmic objects. Not bad for being on the job only five months. Chandra has resolved most of the X-ray background, a pervasive glow of X-rays throughout the universe, first discovered in the early days of space exploration. Before now, scientists have not been able to discern the background's origin, because no X-ray telescope until Chandra has had both the angular resolution and sensitivity to resolve it. "This is a major discovery," said Dr. Alan Bunner, Director of NASA's Structure andEvolution of the universe science theme. "Since it was first observed thirty-seven years ago, understanding the source of the X-ray background has been aHoly Grail of X-ray astronomy. Now, it is within reach." The results of the observation will be discussed today at the 195th national meeting of the American Astronomical Society in Atlanta, Georgia. An article describing this work has been submitted to the journal Nature by Dr. Richard Mushotzky, of NASA Goddard Space Flight Center, Greenbelt, Md., Drs. Lennox Cowie and Amy Barger at the University of Hawaii, Honolulu, and Dr. Keith Arnaud of the University of Maryland, College Park. "We are all very excited by this finding," said Mushotzky. "The resolution of most of the hard X-ray background during the first few months of the Chandra mission is a tribute to the power of this observatory and bodes extremely well for its scientific future," Scientists have known about the X-ray glow, called the X-ray background, since the dawn of X-ray astronomy in the early 1960s. They have been unable to discern its origin, however, for no X-ray telescope until Chandra has had both the angular resolution and sensitivity to resolve it. The German-led ROSAT mission, now completed, resolved much of the lower

    The Villa of Mysteries with its Dionisiac Frieze is one of the well-known buildings of ancient Pompeii. It has been excavated in the early 20th century. Since then many initiatives have been taken for its preservation. Currently, the Frieze is investigated in detail and tests have been made to clean the wall paintings. Non-destructive investigations as infrared thermography (IR), Ground penetrating radar (GPR), and ultrasonic measurements have been performed in order to test if these methods are well suited to reveal the walls' and paintings' structure and to identify the detachments or cracks. IR, GPR and ultrasonic measurements have different penetration capabilities and resolution in depths. So, using these three methods simultaneously can improve the knowledge of the investigated structures at several depths from millimetres and centimetres to metres. It has been tested if detachments of the paintings, cracks, or alterations of the paintings can be detected by passive and active IR measurements. 6 passive and 3 active measurements have been conducted on the Dionisiac Frieze. Lateral temperature differences present at the Frieze are mapped by passive measurements. Here, we show that temperature differences up to about 0.3°C are present and detectable. These small changes in temperature may be related to detachments, cracks, or wet areas. By active IR measurements the paintings are artificially heated by about 1°C and the cooling to normal temperature is observed and analyzed. Lateral differences in the heating and cooling behavior are related to variability in the heat absorption properties and in thermal conductivity. It is shown that detachments as well as restorative treatments are associated with changes in the thermal behavior. In order to image the construction and the condition of the investigated walls, Ground Penetrating Radar (GPR) was measured with a 2 GHz antenna. Each profile was 1.2 m long, the spacing cross-line was 3 cm and in-line 1 mm. The

    Radio astronomers have directly measured the distance to a faraway galaxy, providing a valuable "yardstick" for calibrating large astronomical distances and demonstrating a vital method that could help determine the elusive nature of the mysterious Dark Energy that pervades the Universe. Galaxy UGC 3789 Visible-light image of UGC 3789 CREDIT: STScI "We measured a direct, geometric distance to the galaxy, independent of the complications and assumptions inherent in other techniques. The measurement highlights a valuable method that can be used to determine the local expansion rate of the Universe, which is essential in our quest to find the nature of Dark Energy," said James Braatz, of the National Radio Astronomy Observatory (NRAO), who presented the work to the American Astronomical Society's meeting in Pasadena, California. Braatz and his colleagues used the National Science Foundation's Very Long Baseline Array (VLBA) and Robert C. Byrd Green Bank Telescope (GBT), and the Effelsberg Radio Telescope of the Max Planck Institute for Radioastronomy (MPIfR) in Germany to determine that a galaxy dubbed UGC 3789 is 160 million light-years from Earth. To do this, they precisely measured both the linear and angular size of a disk of material orbiting the galaxy's central black hole. Water molecules in the disk act as masers to amplify, or strengthen, radio waves the way lasers amplify light waves. The observation is a key element of a major effort to measure the expansion rate of the Universe, known as the Hubble Constant, with greatly improved precision. That effort, cosmologists say, is the best way to narrow down possible explanations for the nature of Dark Energy. "The new measurement is important because it demonstrates a one-step, geometric technique for measuring distances to galaxies far enough to infer the expansion rate of the Universe," said Braatz.

    Despite the use of glasses for thousands of years, the nature of the glass transition is still mysterious. On approaching the glass transition, the growth of dynamic heterogeneity has long been thought to play a key role in explaining the abrupt slowdown of structural relaxation. However, it still remains elusive whether there is an underlying link between structural relaxation and dynamic heterogeneity. Here, we unravel the link by introducing a characteristic time scale hiding behind an identical dynamic heterogeneity for various model glass-forming liquids. We find that the time scale corresponds to the kinetic fragility of liquids. Moreover, it leads to scaling collapse of both the structural relaxation time and dynamic heterogeneity for all liquids studied, together with a characteristic temperature associated with the same dynamic heterogeneity. Our findings imply that studying the glass transition from the viewpoint of dynamic heterogeneity is more informative than expected.

    "The Lord of Rings - the mysterious case of the stolen rings" is a live astronomical role-playing game for kids aged 10 -13 [1]. Its goal is to introduce them to some of the main topics of the Solar System: a) the role of gravity; b) the distribution of mass & light; c) the effects of rotation; d) the distribution of water. The game was held at several Science Festival in Italy (Perugia, Genova, Fiorano, Bologna) obtaining great success. Teams of about 6-8 members are introduced to Mr Schioppanelli, the astro-detective of the town (the name is a pun: it reminds Schiaparelli, the famous italian astronomer, and it is a slang expression meaning "ring-breaker"). Mr Schioppanelli has his office in an "gastronomical astronomical observatory", known as The Red Giant Pizzeria. Schioppanelli informs the kids that a mysterious Centaur succeded in stealing the rings of Saturn. The partecipants are appointed astro-detectives incharge and asked to find the rings by browsing around the Solar System, which is scaled so as to fit the town historical centre or a pedestrian area, going from the Sun to Saturn or beyond, depending on the actual area at disposal. Great care must be taken allowing children playing only in a car-free area of the town. At the right scaled distances, the partecipants meet characters playing as the various planets. The kids can talk to them after solving a riddle, obtaining useful informations. A special characters play as a comet, timely going in and out of the inner solar system. The teams can also talk to some shepherdmoons of the rings. They easily discover that the rings were totally destroyed by the Centaur: a real disaster! They are also suggested to gather the necessary ingredients (gravity, light, rotation, inclination, dust and water, represented by simple objects like apples, spinning tops and so on) to rebuild the rings. The kids can buy the ingredients from different planets: every planet has ingredients in quantities which are proportionate to

    Three-dimensional (3D) printing moves beyond interactive 3D graphics and provides an excellent tool for both visual and tactile learners, since 3D printing can now easily communicate complex geometries and full color information. Some limitations of interactive 3D graphics are also alleviated by 3D printable models, including issues of limited software support, portability, accessibility, and sustainability. We describe the motivations, methods, and results of our work on using 3D printing (1) to visualize and understand the η Car Homunculus nebula and central binary system and (2) for astronomy outreach and education, specifically, with visually impaired students. One new result we present is the ability to 3D print full-color models of η Car’s colliding stellar winds. We also demonstrate how 3D printing has helped us communicate our improved understanding of the detailed structure of η Car’s Homunculus nebula and central binary colliding stellar winds, and their links to each other. Attached to this article are full-color 3D printable files of both a red-blue Homunculus model and the η Car colliding stellar winds at orbital phase 1.045. 3D printing could prove to be vital to how astronomer’s reach out and share their work with each other, the public, and new audiences.

  9. Unsolved mystery: the role of BRCA1 in DNA end-joining

    2016-01-01

    Heritable mutations in the tumor suppressor gene BRCA1 increase a woman's lifetime risk of developing breast and ovarian cancer. BRCA1's tumor suppressor function is directly linked to its myriad of functions in the cellular response to DNA double-strand breaks (DSBs). BRCA1 interacts with an extensive array of DNA damage responsive proteins and plays important roles in DSB repair, mediated by the homologous recombination pathway, and in the activation of cell cycle checkpoints. However, the role of BRCA1 in the other two DSB repair pathways, classical non-homologous end-joining (C-NHEJ) and alternative NHEJ (A-NHEJ), remains unclear. In this review, we will discuss the current literature on BRCA1's potential role(s) in modulating both C-NHEJ and A-NHEJ. We also present a model showing that BRCA1 contributes to genomic maintenance by promoting precise DNA repair across all cell cycle phases via the direct modulation of DNA end-joining

    This book provides a broad introduction to the physics and technology of the High Luminosity Large Hadron Collider (HL-LHC). This new configuration of the LHC is one of the major accelerator projects for the next 15 years and will give new life to the LHC after its first 15-year operation. Not only will it allow more precise measurements of the Higgs boson and of any new particles that might be discovered in the next LHC run, but also extend the mass limit reach for detecting new particles. The HL-LHC is based on the innovative accelerator magnet technologies capable of generating 11–13 Tesla fields, with effectiveness enhanced by use of the new Achromatic Telescopic Squeezing scheme, and other state-of-the-art accelerator technologies, such as superconducting compact RF crab cavities, advanced collimation concepts, and novel power technology based on high temperature superconducting links.

    "Linked Data" is a term used in Computer Science to encapsulate a methodology for publishing data and metadata in a structured format so that links may be created and exploited between objects. Berners-Lee (2006) outlines the following four design principles of a Linked Data system: Use Uniform Resource Identifiers (URIs) as names for things. Use HyperText Transfer Protocol (HTTP) URIs so that people can look up those names. When someone looks up a URI, provide useful information, using the standards (Resource Description Framework [RDF] and the RDF query language [SPARQL]). Include links to other URIs so that they can discover more things. In 2010, Berners-Lee revisited his original design plan for Linked Data to encourage data owners along a path to "good Linked Data". This revision involved the creation of a five star rating system for Linked Data outlined below. One star: Available on the web (in any format). Two stars: Available as machine-readable structured data (e.g. An Excel spreadsheet instead of an image scan of a table). Three stars: As two stars plus the use of a non-proprietary format (e.g. Comma Separated Values instead of Excel). Four stars: As three stars plus the use of open standards from the World Wide Web Commission (W3C) (i.e. RDF and SPARQL) to identify things, so that people can point to your data and metadata. Five stars: All the above plus link your data to other people's data to provide context Here we present work building on the SeaDataNet common vocabularies served by the NERC Vocabulary Server, connecting projects such as the Rolling Deck to Repository (R2R) and the Biological and Chemical Oceanography Data Management Office (BCO-DMO) and other vocabularies such as the Marine Metadata Interoperability Ontology Register and Repository and the NASA Global Change Master Directory to create a Linked Ocean Data cloud.

    The Large Hadron Collider (LHC) will become operational in 2005 at The European Laboratory for Particle Physics (CERN). The LHC will be the highest energy proton-proton collider in the world. One of the electronic particle detectors which will operate at the LHC is called ATLAS. The environment for electronics placed within ATLAS is extremely hostile due to the high levels of radiation and the general lack of access to components during the expected 10 year lifetime of the experiment. It is planned to use custom radiation tolerant VCSEL- based optical links to transfer data from the ATLAS inner detector to remote data acquisition electronics. A low mass, non-magnetic and radiation tolerant VCSEL packaging has been developed for the most hostile region in the center of ATLAS where the inner detector is located. The performance of the package is reported on. Qualification tests of commercial VCSELs are also described. The VCSELs were irradiated with neutrons (up to 8.10/sup 14/ n(1 MeV)/cm/sup 2/) and annealing...

    2014-11-01

    Because of its retrogastric location and appearance, which is similar to mesenteric fat, for centuries the pancreas has been a mysterious, hidden organ that has received little attention. However, its importance was intuited and described by Herophilus, Ruphos of Ephesus and Galen. This gland began to appearin distinct medical treatises from the 16th century. There are two important scientists in the history of the pancreas. The fist, Johann Georg Wirsung, described the main pancreatic duct in 1642, a date considered by many to be the start of Pancreatology. The second, Claude Bernard, described pancreatic exocrine function between 1849 and 1856 and is considered the father of pancreatic physiology. Besides these two outstanding figures, there is a constellation of personalities who contributed to improving knowledge of this enigmatic gland with the results of their studies. The aim of this article is to call attention to some of the most notable findings that have enhanced knowledge of this gland over the years. Copyright © 2014 Elsevier España, S.L.U. and AEEH y AEG.

    Globally, chronic kidney disease of unknown aetiology (CKDu) is observed in several areas and among specific ethnic or occupational groups. Given the widespread environmental pollution and the proportions of agriculture workers world-wide, CKDu may be the next global public health issue demanding attention. Recent escalation of CKDu in Sri Lanka has caused a serious public health crisis in the country, made worse by lack of national data. The specific geographic distribution, preponderance among farming population, similar histology findings and absence of usual risk factors for kidney disease indicate undetected nephrotoxic agents playing a role in causation. Some of the challenges for the country are uncoordinated preventive efforts, diverse opinions among stakeholders on causality and fragmented research efforts with limited focus on potential causes of CKDu. As a result, accurate estimation of the CKDu burden, identification of causative agents and implementation of effective actions have been delayed. Stakeholder engagement, with involvement of international experts has been the starting point for finalizing a working case definition to establish community based surveillance as a future platform to conduct long-term research. The country is now poised to contribute to global knowledge by solving the mystery of 'u' in CKDu. This commentary highlights the importance and the mechanisms of making an effective breakthrough as early as possible; failing which CKDu can progress rapidly as demonstrated by the situation in Sri Lanka.

    Full Text Available Sir Geoffrey Hill, long hailed as Britain’s greatest living poet, was devoted to remembering the deceased, those forgotten in the debased din of mass culture—some of them worthy of our emulation, others edifying by their “folly” or “criminality” (Paris Review interview. Hill’s recent death, on 30 June 2016, presents an apt time to remember his own life-work. In its act of memorial as homage, The Mystery of the Charity of Charles Péguy marks a departure for Hill: whereas his earlier work often rests in ambiguity, Péguy labors through the ambiguity—through characteristically antiphonal tones of voice, rhythms, and images—and concludes in affirmation, a note of hope, which points in the direction of some of his later work. Through all of his complexity, Péguy’s life—like Hill’s poem—conforms to a kenotic, Christological pattern and is thus worthy of our emulation.

    Synchrotron-induced X-ray fluorescence (Sy-XRF) analysis was used to study the chemical composition of precious Renaissance silverpoint drawings. Drawings by famous artists such as Albrecht Duerer (1471-1528) and Jan van Eyck (approximately 1395-1441) must be investigated non-destructively. Moreover, extremely sensitive synchrotron- or accelerator-based techniques are needed since only small quantities of silver are deposited on the paper. New criteria for attributing these works to a particular artist could be established based on the analysis of the chemical composition of the metal points used. We illustrate how analysis can give new art historical information by means of two case studies. Two particular drawings, one of Albrecht Duerer, showing a profile portrait of his closest friend, 'Willibald Pirckheimer' (1503), and a second one attributed to Jan van Eyck, showing a 'Portrait of an elderly man', often named 'Niccolo Albergati', are the object of intense art historical controversy. Both drawings show inscriptions next to the figures. Analyses by Sy-XRF could reveal the same kind of silverpoint for the Pirckheimer portrait and its mysterious Greek inscription, contrary to the drawing by Van Eyck where at least three different metal points were applied. Two different types of silver marks were found in this portrait. Silver containing gold marks were detected in the inscriptions and over-subscriptions. This is the first evidence of the use of gold points for metal point drawings in the Middle Ages

    O final do século XVIII na Inglaterra foi marcado pelo início da consolidação de um novo gênero literário, o romance. Este gênero já se destacava na época pela participação significativa das mulheres, tanto como leitoras como escritoras. Este fato foi provavelmente encorajado, entre outros aspectos, pela Revolução Industrial que reorganizou e mudou inúmeros aspectos da vida doméstica e conjugal. Neste contexto, o Romance Gótico foi um dos tipos de romance mais populares e Ann Radcliffe, a romancista mais renomada. Esse artigo discute The Mysteries of Udolpho (1794, quarto livro escrito por Radcliffe, com foco na análise do espaço. O espaço é apresentado e descrito em detalhe ao longo da narrativa, o que evidencia sua importância neste romance. Os dois tipos de espaço, doméstico e externo, são analisados a fim de compreendermos a sua função neste romance.

  18. Unraveling mysteries of personal performance style; biomechanics of left-hand position changes (shifting) in violin performance.

    Instrumental music performance ranks among the most complex of learned human behaviors, requiring development of highly nuanced powers of sensory and neural discrimination, intricate motor skills, and adaptive abilities in a temporal activity. Teaching, learning and performing on the violin generally occur within musico-cultural parameters most often transmitted through aural traditions that include both verbal instruction and performance modeling. In most parts of the world, violin is taught in a manner virtually indistinguishable from that used 200 years ago. The current study uses methods from movement science to examine the "how" and "what" of left-hand position changes (shifting), a movement skill essential during violin performance. In doing so, it begins a discussion of artistic individualization in terms of anthropometry, the performer-instrument interface, and the strategic use of motor behaviors. Results based on 540 shifting samples, a case series of 6 professional-level violinists, showed that some elements of the skill were individualized in surprising ways while others were explainable by anthropometry, ergonomics and entrainment. Remarkably, results demonstrated each violinist to have developed an individualized pacing for shifts, a feature that should influence timing effects and prove foundational to aesthetic outcomes during performance. Such results underpin the potential for scientific methodologies to unravel mysteries of performance that are associated with a performer's personal artistic style.

  1. Helically linked mirror arrangement

    Ranjan, P.

    1986-08-01

    A scheme is described for helical linking of mirror sections, which endeavors to combine the better features of toroidal and mirror devices by eliminating the longitudinal loss of mirror machines, having moderately high average β and steady state operation. This scheme is aimed at a device, with closed magnetic surfaces having rotational transform for equilibrium, one or more axisymmetric straight sections for reduced radial loss, a simple geometrical axis for the links and an overall positive magnetic well depth for stability. We start by describing several other attempts at linking of mirror sections, made both in the past and the present. Then a description of our helically linked mirror scheme is given. This example has three identical straight sections connected by three sections having helical geometric axes. A theoretical analysis of the magnetic field and single-particle orbits in them leads to the conclusion that most of the passing particles would be confined in the device and they would have orbits independent of pitch angle under certain conditions. Numerical results are presented, which agree well with the theoretical results as far as passing particle orbits are concerned

  2. A 'mystery client' evaluation of adolescent sexual and reproductive health services in health facilities from two regions in Tanzania.

    Zaina Mchome

    Full Text Available Unwelcoming behaviours and judgemental attitudes have long been recognised as a barrier to young people's access to reproductive health services. Over the last decade youth friendly reproductive health services have been promoted and implemented world-wide. However, long term evidence of the impact of these programmes is lacking. We report the results of a large mystery client evaluation of adolescent sexual and reproductive health services in Tanzania, a country that has had a long established youth friendly policy. Forty-eight visits made to thirty-three health facilities were conducted by twelve young people (six in each region trained to perform three different scripted scenarios (i.e., condom request, information on sexually transmitted infections and family planning. The study revealed barriers in relation to poor signage and reception for services. In addition health workers demonstrated paternalistic attitudes as well as lack of knowledge about adolescent sexual and reproductive health services. In some cases, health workers discouraged young people from using services such as condoms and family planning methods. Lack of confidentiality and privacy were also noted to be common challenges for the young people involved. Intervention strategies that focus on changing health workers' mind-set in relation to adolescent sexual and reproductive health are crucial for ensuring quality provision of sexual and reproductive health services to young people. The study identified the importance of reception or signs at the health units, as this can facilitate young people's efforts in seeking sexual and reproductive health services. Likewise, improvement of health workers knowledge of existing policy and practice on sexual and reproductive health services and youth friendly services is much needed.

  3. What Are Women Told When Requesting Family Planning Services at Clinics Associated with Catholic Hospitals? A Mystery Caller Study.

    Catholic Church directives restrict family planning service provision at Catholic health care institutions. It is unclear whether obstetrics and gynecology clinics that are owned by or have business affiliations with Catholic hospitals offer family planning appointments. Mystery callers phoned 144 clinics nationwide that were found on Catholic hospital websites between December 2014 and February 2016, and requested appointments for birth control generally, copper IUD services specifically, tubal ligation and abortion. Chi-square and Fisher's exact tests assessed potential correlates of appointment availability, and multivariable logistic regressions were computed if bivariate testing suggested multiple correlates. Although 95% of clinics would schedule birth control appointments, smaller proportions would schedule appointments for copper IUDs (68%) or tubal ligation (58%); only 2% would schedule an abortion. Smaller proportions of Catholic-owned than of Catholic-affiliated clinics would schedule appointments for birth control (84% vs. 100%), copper IUDs (4% vs. 97%) and tubal ligation (29% vs. 72%); for birth control and copper IUD services, no other clinic characteristics were related to appointment availability. Multivariable analysis confirmed that tubal ligation appointments were less likely to be offered at Catholic-owned than at Catholic-affiliated clinics (odds ratio. 0.1); location and association with one of the top 10 Catholic health care systems also were significant. Adherence to church directives is inconsistent at Catholic-associated clinics. Women visiting such clinics who want highly effective methods may need to rely on less effective methods or delay method uptake while seeking services elsewhere.

  4. Young Stars in Orion May Solve Mystery of Our Solar System

    Science.gov (United States)

    2001-09-01

    very close to the Solar System's progenitor gas cloud, simultaneously triggering its collapse and seeding it with short-lived isotopes. Solar flares could produce such isotopes, but the flares would have to be hundreds of thousands of times more powerful and hundreds of times more frequent than those our Sun generates. Enter the stars in the Orion Nebula. This star-forming region has several dozen new stars nearly identical to our Sun, only much younger. Feigelson's team used Chandra to study the flaring in these analogs of the early Sun and found that nearly all exhibit extremely high levels of X-ray flaring--powerful and frequent enough to forge many of the kinds of isotopes found in the ancient meteorites from the early solar system. "This is a very exciting result for space X-ray astronomy," said Donald Clayton, Centennial Professor of Physics and Astronomy at Clemson University. "The Chandra Penn State team has shown that stellar-flare acceleration produces radioactive nuclei whether we want them or not. Now the science debate can concentrate on whether such irradiation made some or even all of the extinct radioactivities that were present when our solar system was formed, or whether some contamination of our birth molecular cloud by external material is also needed." "This is an excellent example of how apparently distant scientific fields, like X-ray astronomy and the origins of solar systems, can in fact be closely linked," said Feigelson. The Orion observation was made with Chandra's Advanced CCD Imaging Spectrometer, which was conceived and developed for NASA by Penn State and Massachusetts Institute of Technology under the leadership of Gordon Garmire, the Evan Pugh Professor of Astronomy and Astrophysics at Penn State. The Penn State observation team includes Pat Broos, James Gaffney, Gordon Garmire, Leisa Townsley and Yohko Tsuboi. Collaborators also include Lynne Hillenbrand of CalTech and Steven Pravdo of the NASA Jet Propulsion Laboratory. Background

    1988-01-01

    The multitude of different supplements recommended for animals grazing natural pastures, which testifies to the need for a metabolic basis for supplementary feeding practices. The first approach to this problem was to simulate different feeding conditions in the laboratory, where the metabolic responses of body tissues to changes in the supply of purified nutrients could be studied using radioisotope techniques. The second step was to link these fundamental studies to field conditions. The results of these studies suggest that the efficiency of feed conversion and growth rates of ruminants grazing winter pastures in the highveld region of South Africa could be substantially improved by strategic supplementation with glucose precursors. Acetate clearance rate represents a valuable link in the process of applying information obtained from controlled laboratory experiments to field conditions. As this technique is inexpensive, quick and simple to carry out, it is ideally suited to application under field conditions where the use of isotopes is impractical. By providing a link with field conditions, it greatly extended the scope and practical application of isotope tracer techniques

    Rolfsen's beautiful book on knots and links can be read by anyone, from beginner to expert, who wants to learn about knot theory. Beginners with a basic background find an inviting introduction to the elements of topology, emphasizing the tools needed for understanding knots, the fundamental group and van Kampen's theorem, for example, which are then applied to concrete problems, such as computing knot groups. For experts, Rolfsen explains advanced topics, such as the connections between knot theory and surgery and how they are useful to understanding three-manifolds. Besides providing a guide

  10. The mysterious Misirlou

    2013-01-01

    Full Text Available My article deals with an unusual story on the roots of a song that has left a significant imprint on the twentieth century popular music all over the world. It is the song Misirlou, created somewhere on the territory of the Ottoman Empire, probably in Asia Minor. The author of this song is unknown. It was created in the so-called rebetiko musical style, typical of the Greeks from Asia Minor, who developed that style after the World War I. The first recordings of this song were made in the 1930s by Greek musicians Tethos Demetriades and Mihalis Patrinos. In no time, there was a true proliferation of different versions of this song, in almost every possible musical genre: jazz, latino, taksym, klezmer, makam, Serbian folk, hip hop, trash metal, pop and rock’n’roll. A number of these versions are mentioned in the article. The fact that this song is considered by many nations – Greeks, Turks, Arabs, Serbs, Jews, Americans – as their own, demonstrates its aptitude for incredible metamorphoses. What attracted me to this song was the story on how it was appropriated into Serbian folk music by the remarkable composer and singer Dragoljub Dragan Toković. The song was called Lela Vranjanka [Lela, the girl from Vranje] and became a standard in the so-called “Vranje folk music”, marvelously interpreted by the singer Staniša Stošić. I also compare various textual versions of Misirlou, in different languages, in order to show its parallel development in verse.

  11. The Mysterious Southern Torque

    McDowell, M. S.

    2004-05-01

    Something weird happened to twist the southern hemisphere out of alignment with the northern, as evidenced by the positions of the mountain ranges of North and South America, the Atlantic MAR, and the closure of West Africa to North America - all smooth were the torque reversed. What happened, and when, and why? We identify a number of global "cracks" of almost exactly the same length and direction, with some, even more peculiarly, turning the same angle, and proceeding an equal distance in the new direction. The Emperor-Hawaiian chain, the Louisville chain and the west coast of North America, as examples, are essentially parallel. Their northerly legs follow the angle of the axis of orbital ellipse. But then they all make equal 45 degree easterly bends, to 17.5 NW, and continue on, still parallel, for very similar distances. It is the same at the north coast of South America, and the mid-section of the MAR from 46W to 12W. It is the distance from the Cameroons to Kenya, from the south end of the Red Sea to the SE Indian Ridge at the Nema Fracture zone, from west to east of the Nazca plate.What is all this? Coincidence? Seeing things? Researchers have attributed plate motion or hot spot motion or both or absolutely none, to all of the above. Geophysicists have dated the surfaces from Archean to Pleistocene by all possible scientific means, certainly no possible correlation can be made. Yet we postulate the physical reality can be demonstrated. It is so global a phenomenon that it is well beyond what a hot spot or a plate could do. Even a really tremendous impact would have trouble making such precise geometric arrangements. So what is it - perhaps the angle of rotation, or the inertia of northern hemisphere mass above the geoid? And if so, then, what changed it? It would seem that some huge imbalance occurred. Suppose the whole bottom blew out of the southern hemisphere, and the center of mass drastically altered. Suppose some unknown universal force changed our composition - magnetic or other. Were the magnetic poles ever the elliptic axis? What this world needs is a few more outrageous ideas.

    Full Text Available ABSTRACT: The economic opportunity hypothesis states that perceived shrinkage of opportunity discourages women or couples from embarking on marriage or reproduction. On the contrary, the sense that opportunity is expanding encourages couples to raise their family-size target. The hypothesis assumes that humans are genetically programmed to maximize successful reproduction by having more offspring when environmental/economic conditions appear favorable, but exercise restraint --- waiting or limiting the total number of offspring --- if the latter strategy promises greater longrun success.

    An account is given of the growth of human understanding of comets with emphasis initially placed on theories developed before the twentieth century and subsequently on information regarding the nature of comets, their origin and possible relation to life on earth. Special consideration is given to a description of how the author arrived at his own model of the origin and nature of comets, the dirty snowball theory. The significance of comets (i.e. the hazards they may represent) is assessed and space missions to Halley's comet together with the first landing on a comet (tentatively planned for 1995) are described. It is noted that this growth of cometary understanding is presented as an integral part of the growth of science and technology. 14 references

    We comment on short- and long-term pulsation period variations of Z CVn, a classical RR Lyrae star with the Blazhko effect. Z CVn shows cyclic-like O-C diagram that can be interpreted as a consequence of binarity throught the light travel time effect. We show that this hypothesis is false and that the observed long-term period variations must be caused by some effect that is intrinsic to the star. We also show that the Blazhko period is not simply anti-correlated with the long-term period variations as was suggested by previous authors.

    CERN Document Server

    Rubtsov, Vladimir

    2009-01-01

    The purpose of the book is a dual one: to detail the nature and results of Tunguska investigations in the former USSR and present-day CIS, and to destroy two long-standing myths still held in the West. The first concerns alleged “final solutions” that have ostensibly been found in Russia or elsewhere. The second concerns the mistaken belief that there has been little or no progress in understanding the nature of the Tunguska phenomenon. All this is treated by the author in a scholarly and responsible manner. Although the book does present certain unusual findings of Russian and Ukrainian scholars, it is important to stress that this is not a sensational book; it is, rather, a serious exposition of the results of rational investigations into a difficult scientific problem. We are demonstrating the true complexity of the problem that is now entering its second century of existence. Simple meteoritic models cannot explain all the characteristics of this complicated event, and therefore certain so-called “u...

Two sets of lower molecular weight proteins of 30-31 kDa and 24-26 kDa also contained link protein epitopes recognized by the monoclonal antibody and were most likely degradative products of the intact link proteins. The link proteins of 48 and 40 kDa were identified as phosphoproteins while the 44 kDa link protein did not contain 32 P. The phosphorylated 48 and 40 kDa link proteins contained approximately 2 moles PO 4 /mole link protein

    Expectancy-value theory (EVT) is a dominant theory of human motivation. Historically, the Expectancy × Value interaction, in which motivation is high only if both expectancy and value are high, was central to EVT. However, the Expectancy × Value interaction mysteriously disappeared from published research more than 25 years ago. Using large representative samples of 15-year-olds (N = 398,750) from 57 diverse countries, we attempted to solve this mystery by testing Expectancy × Value interactions using latent-variable models with interactions. Expectancy (science self-concept), value (enjoyment of science), and the Expectancy × Value interaction all had statistically significant positive effects on both engagement in science activities and intentions of pursuing scientific careers; these results were similar for the total sample and for nearly all of the 57 countries considered separately. This study, apparently the strongest cross-national test of EVT ever undertaken, supports the generalizability of EVT predictions--including the "lost" Expectancy × Value interaction.

    Various aspects of knot theory are discussed when fermionic degrees of freedom are taken into account in the braid group representations and in the state models. It is discussed how the R matrix for the Alexander polynomial arises from the Fox differential calculus, and how it is related to the quantum group U q gl(1,1). New families of solutions of the Yang Baxter equation obtained from ''linear'' representations of the braid group and exterior algebra are investigated. State models associated with U q sl(n,m), and in the case n=m=1 a state model for the multivariable Alexander polynomial are studied. Invariants of links in solid handlebodies are considered and it is shown how the non trivial topology lifts the boson fermion degeneracy is present in S 3 . (author) 36 refs

    In this chapter we propose to expand and enhance the understanding of wayfi nding beyond the strictly “instrumental” (i.e., getting from point A to point B), to include the qualities and multi-sensorial inputs that inform and shape people’s movement through space. We take as a point of departure...... of environmental information , which includes the embodied, multi-sensorial experience of moving through physical space. We base our examination in part on the classic positions of the wayfi nding literature—for example, Lynch’s seminal study, The Image of the City ( 1960 ). However, we also examine the so......-called mobilities turn in which mobility is viewed as a complex, multilayered process that entails much more than simply getting from point A to point B (see Cresswell 2006 ; Jensen 2013 ; Urry 2007 ).The structure of the chapter is simple: We fi rst introduce the concepts that are key to linking wayfi nding...

    The project described in this paper aims to provide assistive tools to support elderly people affected by vestibular dysfunction (i.e. a form of balance disorder leading to dizziness and nausea) in their home-based rehabilitation activities. Challenges emerge as the rehabilitation moves from...... a supervised hospital setting to private homes. Our studies have shown that the elderly people are less motivated to perform the training at home. This paper presents a tangible, portable, two dimensional modular platform called LinkLights that has been developed to sustain the home-based rehabilitation......, giving clear guidelines what to do, adding motivational cues and elements of variation and surprise in the activity. Furthermore, a set of challenges for successful translocation of the therapeutic regimen from a supervised, hospital setting to an unsupervised home-based setting together with some early...

  16. Named Entity Linking Algorithm

    Full Text Available In the tasks of processing text in natural language, Named Entity Linking (NEL represents the task to define and link some entity, which is found in the text, with some entity in the knowledge base (for example, Dbpedia. Currently, there is a diversity of approaches to solve this problem, but two main classes can be identified: graph-based approaches and machine learning-based ones. Graph and Machine Learning approaches-based algorithm is proposed accordingly to the stated assumptions about the interrelations of named entities in a sentence and in general.In the case of graph-based approaches, it is necessary to solve the problem of identifying an optimal set of the related entities according to some metric that characterizes the distance between these entities in a graph built on some knowledge base. Due to limitations in processing power, to solve this task directly is impossible. Therefore, its modification is proposed. Based on the algorithms of machine learning, an independent solution cannot be built due to small volumes of training datasets relevant to NEL task. However, their use can contribute to improving the quality of the algorithm. The adaptation of the Latent Dirichlet Allocation model is proposed in order to obtain a measure of the compatibility of attributes of various entities encountered in one context.The efficiency of the proposed algorithm was experimentally tested. A test dataset was independently generated. On its basis the performance of the model was compared using the proposed algorithm with the open source product DBpedia Spotlight, which solves the NEL problem.The mockup, based on the proposed algorithm, showed a low speed as compared to DBpedia Spotlight. However, the fact that it has shown higher accuracy, stipulates the prospects for work in this direction.The main directions of development were proposed in order to increase the accuracy of the system and its productivity.

    2015-06-01

    Full Text Available Since the advent of Linked Data (LD as a method for building webs of data, there have been many attempts to apply and implement LD in various settings. Efforts have been made to convert bibliographic data in libraries into Linked Data, thereby generating Library Linked Data (LLD. However, when memory institutions have tried to link their data with external sources based on principles suggested by Tim Berners-Lee, identifying appropriate vocabularies for use in describing their bibliographic data has proved challenging. The objective of this paper is to discuss the potential role of Linked Open Vocabularies (LOV in providing better access to various open datasets and facilitating effective linking. The paper will also examine the ways in which memory institutions can utilize LOV to enhance the quality of LLD and LLD-based ontology design.

    Objective Injury, the most common type of pediatric trauma, can lead to a number of adverse psychosocial outcomes, including posttraumatic stress disorder. Currently, few evidence-based parent programs exist to support children hospitalized after a traumatic injury. Using methods in evaluation and intervention research, we completed a formative research study to develop a new program of psychological first aid, Link for Injured Kids, aimed to educate parents in supporting their children after a severe traumatic injury. Methods Using qualitative methods, we held focus groups with parents and pediatric trauma providers of children hospitalized at a Level I Children's Hospital because of an injury in 2012. We asked focus group participants to describe reactions to trauma and review drafts of our intervention materials. Results Health professionals and caregivers reported a broad spectrum of emotional responses by their children or patients; however, difficulties were experienced during recovery at home and upon returning to school. All parents and health professionals recommended that interventions be offered to parents either in the emergency department or close to discharge among admissions. Conclusions Results from this study strongly indicate a need for posttrauma interventions, particularly in rural settings, to support families of children to address the psychosocial outcomes in the aftermath of an injury. Findings presented here describe the process of intervention development that responds to the needs of an affected population. PMID:26428077

    The Compact Muon Solenoid (CMS) is a multi-purpose detector that is going to be installed in the future Large Hadron Collider (LHC) at CERN. Muons are one of the main physical signatures of the expected new physics. The muons are going to be detected by the Central Tracker (CT) and the Muon Spectrometer (MS). Both, the CT and MS can provide an independent muon momentum measurement, but for all η and momentum values the highest precision for muon momentum measurement is achieved when the muon tracks are reconstructed using both tracking detectors. The calorimeters and the solenoid volumes separate about three meters the CT and the MS. It has been shown that the alignment of the CT with respect to the MS can not be guaranteed by a software alignment in a reasonable time scale. Therefore, an opto-mechanical system (the multipoint link system) have been designed to monitor, on-line, the relative position of both sub-detectors providing a common reference frame for both of them. The local alignment of the muon barrel spectrometer determines the relative position of the muon chambers with respect to themselves and also with respect to a carbon fiber rigid structure called MAB (Module for the Alignment of the Barrel). There are a total of 36 MABs distributed in the boundary planes of each muon spectrometer sector. This paper describes all the equipment and presents the principle of measurement. (author)

    Full Text Available Introduction The number of patients suffering from diabetes mellitus is growing globally. It is expected to observe 253.4 million sufferers in geriatric population in 2045. In this time, also 131.5 million of people is going to have dementia and other cognitive problems. In people aged over 65 these two diseases are concomitant quite often. What are the connections in the area of etiology and treatment? Aim The purpose of this study is to present links between dementia and diabetes are depicted in professional literature. Results Diabetes and dementia are associated on many levels. These conditions have common risk factors. Diabetes may contribute to cognitive impairment in many ways, promoting development of atherosclerosis, brain vessel damage and vascular dementia. Alzheimer disease may be promoted by hyperglycemia and hyperinsulinemia. On contrary also hypoglycaemia, often met in elderly diabetic patients has negative impact on cognitive function. Dementia seriously affects treatment of diabetes. The main problems are not satisfying adherence and diabetes self-management. Conclusions Prevention of diabetes and dementia risk factors can be performed simultaneously as the are common for both diseases. Enhancing physical activity, reducing saturated fats consumption, levels of cholesterol and body mass are considered to be beneficial in the context of described conditions. Furthermore, treatment of diabetes is strongly affected by cognitive dysfunction. Management of dementive diabetics requires individualization and using long-acting drugs. It is crucial to reduce risk of life-threatening hypoglycaemias and to create wide team to take care of these patients.

  2. Hierarchical Linked Views

    Energy Technology Data Exchange (ETDEWEB)

    Erbacher, Robert; Frincke, Deb

    2007-07-02

    Coordinated views have proven critical to the development of effective visualization environments. This results from the fact that a single view or representation of the data cannot show all of the intricacies of a given data set. Additionally, users will often need to correlate more data parameters than can effectively be integrated into a single visual display. Typically, development of multiple-linked views results in an adhoc configuration of views and associated interactions. The hierarchical model we are proposing is geared towards more effective organization of such environments and the views they encompass. At the same time, this model can effectively integrate much of the prior work on interactive and visual frameworks. Additionally, we expand the concept of views to incorporate perceptual views. This is related to the fact that visual displays can have information encoded at various levels of focus. Thus, a global view of the display provides overall trends of the data while focusing in on individual elements provides detailed specifics. By integrating interaction and perception into a single model, we show how one impacts the other. Typically, interaction and perception are considered separately, however, when interaction is being considered at a fundamental level and allowed to direct/modify the visualization directly we must consider them simultaneously and how they impact one another.

    of JCE in the mail each month, and I expect you do too. I can glance at the cover to get an overview of an issue's content, and I usually am enticed inside by intriguing cover art. I can scan the table of contents to find articles I want to read, or I can just browse through the issue to see what looks interesting. Usually the editors have juxtaposed related articles so that I often find a small treasure trove. The printed Journal is quite portable and can be read in a car or airplane. It will last a long time, and until the paper deteriorates, I will never have a problem reading back issues. I have almost every issue from the first day I subscribed and have even added some older ones from collections of retired colleagues who no longer had shelf space for them. I certainly would not want to give up my printed copies, and I want to keep getting them. I find that JCE Online provides a different kind of resource that is equally valuable. It contains more information, and information that is more appropriate in electronic form. It links related ideas into a much more complex web of information than is possible in print. And it opens pathways to lots of information that is not part of JCE but resides elsewhere. Using this issue as an example, let's take a tour of what JCE Online can do. Point your Web browser to http://jchemed.chem.wisc.edu Click on Journal and then on Current Issue (unless September 1999 is no longer the current issue, in which case you will find it in Past Issues). In the table of contents, find the article "UV Catalysis, Cyanotype Photography, and Sunscreens". Click on the title. When the abstract appears, click on Full Text (PDF) to see the article, just as it appears on page 1199 in this issue. When you are prompted, enter the name and subscriber number from your address label. At the end of the article you will find that supplementary materials are available (including a procedure for testing sunscreens) and you can click on the link to view them

  4. Object linking in repositories

    Eichmann, David (Editor); Beck, Jon; Atkins, John; Bailey, Bill

    1992-01-01

    This topic is covered in three sections. The first section explores some of the architectural ramifications of extending the Eichmann/Atkins lattice-based classification scheme to encompass the assets of the full life cycle of software development. A model is considered that provides explicit links between objects in addition to the edges connecting classification vertices in the standard lattice. The second section gives a description of the efforts to implement the repository architecture using a commercially available object-oriented database management system. Some of the features of this implementation are described, and some of the next steps to be taken to produce a working prototype of the repository are pointed out. In the final section, it is argued that design and instantiation of reusable components have competing criteria (design-for-reuse strives for generality, design-with-reuse strives for specificity) and that providing mechanisms for each can be complementary rather than antagonistic. In particular, it is demonstrated how program slicing techniques can be applied to customization of reusable components.

    Highlights: • We investigate the voltage settings for the four-element injection lens of an HDA. • The two well-known approaches, BEM and FDM, in charged particle optics were used. • We tested optimal lens voltages from simulation on the actual experimental setup. • The measured FWHM were well modeled using realistic source parameters. • The results are helpful to experimenters. - Abstract: The methodology and results of a detailed four-element lens optimization analysis based on electron trajectory numerical simulations are presented for a hemispherical deflector analyzer (HDA), whose entry aperture size is determined by the injection lens itself and is therefore virtual. Trajectory calculations were performed using both the boundary-element method (BEM) and the finite-difference method (FDM) and results from these two different approaches were benchmarked against each other, to probe and confirm the accuracy of our results. Since the first and last electrode are held at fixed potentials, the two intermediate adjustable lens electrode voltages were varied over the entire available voltage space in a direct, systematic, brute-force approach, while minima in beam spot size on the 2-D position sensitive detector (PSD) at the exit of the HDA were investigated using a beam shaping approach. Lens voltages demonstrating improved energy resolution for the combined lens/HDA/PSD spectrograph system were sought with and without pre-retardation. The optimal voltages were then tested experimentally on the modeled HDA system using a hot-wire electron gun. The measured energy resolution was found to be in good overall agreement with our simulations, particularly at the highest resolution (∼0.05%) working conditions. These simulations also provide a detailed insight to the distinctive trajectory optics and positions of the first and second image planes, when the PSD has to be placed some distance away from the HDA exit plane, and is therefore not at the ideal optics conjugate image position. The substantial time savings afforded over usual trial-and-error experimentation should make this type of make-do simulation approach attractive to experimentalists.

    Young men who have sex with men (YMSM) are at increased risk for HIV and STI infection. While encouraging HIV and STI testing among YMSM remains a public health priority, we know little about the cultural competency of providers offering HIV/STI tests to YMSM in public clinics. As part of a larger intervention study, we employed a mystery shopper methodology to evaluate the LGBT cultural competency and quality of services offered in HIV and STI testing sites in Southeast Michigan (n = 43).We trained and deployed mystery shoppers (n = 5) to evaluate the HIV and STI testing sites by undergoing routine HIV/STI testing. Two shoppers visited each site, recording their experiences using a checklist that assessed 13 domains, including the clinic's structural characteristics and interactions with testing providers. We used the site scores to examine the checklist's psychometric properties and tested whether site evaluations differed between sites only offering HIV testing (n = 14) versus those offering comprehensive HIV/STI testing (n = 29). On average, site scores were positive across domains. In bivariate comparisons by type of testing site, HIV testing sites were more likely than comprehensive HIV/STI testing clinics to ascertain experiences of intimate partner violence, offer action steps to achieve safer sex goals, and provide safer sex education. The developed checklist may be used as a quality assurance indicator to measure HIV/STI testing sites' performance when working with YMSM. Our findings also underscore the need to bolster providers' provision of safer sex education and behavioral counseling within comprehensive HIV/STI testing sites.

    For 2 weeks in the fall of 2017, traces of the isotope ruthenium-106 wafted across Europe. The radioactive cloud was too thin to be dangerous, but it posed a mystery to scientists. Now, researchers at the French Institute of Radioprotection and Nuclear Security say the isotope may have been released from the Mayak nuclear facility in southern Russia. They argue the leak may have happened when technicians botched the fabrication of a cerium-144 source needed in the search for sterile neutrinos at the Gran Sasso National Laboratory in L'Aquila, Italy. The Russian government has vehemently denied that an accident took place, however.

    It is possible to expand the data acquisition capabilities of an existing process computer to include other dedicated computer based systems, provided each system has at least minimal data link capabilities. The following paper discusses the addition of three computer based acquisition systems to a Honeywell 4500C (also designated the 45000) running the SEER system. Only one data link port was required to support the link. Each of the three specialized systems implemented data link protocols used by their suppliers in previous projects: none of the three were compatible with Honeywell's protocol. Part one of the following provides a generic overview of the project and would be relevent to the operator of any process system interested in expansion. Part two provides specific details of this project and may serve to provide performance benchmarks to those who wish to consider a similar project

  16. Khovanov homology of graph-links

    Energy Technology Data Exchange (ETDEWEB)

    Nikonov, Igor M [M. V. Lomonosov Moscow State University, Faculty of Mechanics and Mathematics, Moscow (Russian Federation)

    2012-08-31

    Graph-links arise as the intersection graphs of turning chord diagrams of links. Speaking informally, graph-links provide a combinatorial description of links up to mutations. Many link invariants can be reformulated in the language of graph-links. Khovanov homology, a well-known and useful knot invariant, is defined for graph-links in this paper (in the case of the ground field of characteristic two). Bibliography: 14 titles.

  17. LinkMind: link optimization in swarming mobile sensor networks.

    Science.gov (United States)

    Ngo, Trung Dung

    2011-01-01

    A swarming mobile sensor network is comprised of a swarm of wirelessly connected mobile robots equipped with various sensors. Such a network can be applied in an uncertain environment for services such as cooperative navigation and exploration, object identification and information gathering. One of the most advantageous properties of the swarming wireless sensor network is that mobile nodes can work cooperatively to organize an ad-hoc network and optimize the network link capacity to maximize the transmission of gathered data from a source to a target. This paper describes a new method of link optimization of swarming mobile sensor networks. The new method is based on combination of the artificial potential force guaranteeing connectivities of the mobile sensor nodes and the max-flow min-cut theorem of graph theory ensuring optimization of the network link capacity. The developed algorithm is demonstrated and evaluated in simulation.

    A wide spectrum of maturing methods and tools, collectively characterized as the Semantic Web, is helping to vastly improve the dissemination of scientific research. Creating semantic integration requires input from both domain and cyberinfrastructure scientists. OceanLink, an NSF EarthCube Building Block, is demonstrating semantic technologies through the integration of geoscience data repositories, library holdings, conference abstracts, and funded research awards. Meeting project objectives involves applying semantic technologies to support data representation, discovery, sharing and integration. Our semantic cyberinfrastructure components include ontology design patterns, Linked Data collections, semantic provenance, and associated services to enhance data and knowledge discovery, interoperation, and integration. We discuss how these components are integrated, the continued automated and semi-automated creation of semantic metadata, and techniques we have developed to integrate ontologies, link resources, and preserve provenance and attribution.

  5. A TALE OF THREE MYSTERIOUS SPECTRAL FEATURES IN CARBON-RICH EVOLVED STARS: THE 21 μm, 30 μm, AND “UNIDENTIFIED INFRARED” EMISSION FEATURES

    2015-03-20

    The mysterious “21 μm” emission feature seen almost exclusively in the short-lived protoplanetary nebula (PPN) phase of stellar evolution remains unidentified since its discovery two decades ago. This feature is always accompanied by the equally mysterious, unidentified “30 μm” feature and the so-called “unidentified infrared” (UIR) features at 3.3, 6.2, 7.7, 8.6, and 11.3 μm which are generally attributed to polycyclic aromatic hydrocarbon (PAH) molecules. The 30 μm feature is commonly observed in all stages of stellar evolution from the asymptotic giant branch through PPN to the planetary nebula phase. We explore the interrelations among the mysterious 21, 30 μm, and UIR features of the 21 μm sources. We derive the fluxes emitted in the observed UIR, 21, and 30 μm features from published Infrared Space Observatory or Spitzer/IRS spectra. We find that none of these spectral features correlate with each other. This argues against a common carrier (e.g., thiourea) for both the 21 μm feature and the 30 μm feature. This also does not support large PAH clusters as a possible carrier for the 21 μm feature.

    The Versatile Link PLUS project targets the phase II upgrades of the ATLAS and CMS experiments. It will develop a radiation resistant optical link, operating at up to 10 Gb/s in the upstream and up to 5 Gb/s in the downstream directions with a smaller footprint and higher channel count than its predecessor. A low-profile package is being developed that allows volume production at reduced costs, but which nevertheless can be configured to suit the individual channel count needs of different detectors. This paper describes the development strategies and summarizes the status of the feasibility demonstration phase of the project.

  7. The Mysterious Fall of Soeharto: A Genre Analysis of Richard Mann’s Plots and Schemes that Brought Down Soeharto (PSBDS

    Full Text Available The real cause of Soeharto’s fall from the Indonesian presidency remains a mystery. Richard Mann (1998 launched three significant rhetorical questions: (a Was President Soeharto toppled by student demonstrators and people’s power? (b Was he brought down by the withdrawal of support from the United States? (c Or, was his sudden fall brought about by all of the two plus large doses of Oriental plotting and scheming? This article attempts to analyze Richard Mann’s PSBDS in terms of its macrostructure in order to find out the real cause of Soeharto’s fall. The analysis is substantiated by different resources as linguistic evidences, to justify the validity of the findings. The study revealed a proposition that critical reading is the key to successful comprehension of a text which may include a crosschecking with other resources, a careful identification of the generic structure of a text, and paying attention to how an author positions his or her readers. The article concludes, that in fact, Soeharto resigned from presidency on his own wisdom in order to avoid more bloodshed in Indonesian dreamland.

  8. How well are national guidelines relating to the general sales of aspirin and paracetamol, adhered to by retail stores: a mystery shopper study

    Molloy, Phillip; Chambers, Ruth; Cork, Tania

    2016-01-01

    Objective To determine whether non-pharmaceutical retail outlets are aboding to the current Medicines and Healthcare products Regulatory Agency (MHRA) national guidelines for over-the-counter (OTC) sales of aspirin and paracetamol. Methods Stages 1 and 2 of the study deployed eight and four medical students, respectively, to undertake a mystery shopper style investigation. Stage 1: eight medical students attempted to buy ≥96 tablets/capsules aspirin or paracetamol in one transaction in 62 shops. Stage 2: four medical students attempted to purchase 32 paracetamol 500 mg along with a ‘flu remedy preparation also containing paracetamol, in 54 shops. Results Stage 1 data revealed that 58% and 57% retailers sold more than the MHRA guidelines recommended for paracetamol and aspirin, respectively. We observed that 23% and 28% retailers were willing to sell ≥96 tablets of paracetamol or aspirin with no questions asked. Stage 2 results showed that 57% retailers sold 32×500 mg paracetamol in conjunction with a paracetamol-containing ‘flu preparation; while 98% shops sold 16×paracetamol 500 mg along with a paracetamol-containing ‘flu remedy, with no questions asked of the shopper or advice given. Discussion MHRA national guidelines for OTC medicines sales appear to be poorly adhered to in non-pharmacy shops. Sales of aspirin and paracetamol OTC must be better regulated in the UK to ultimately reduce morbidity and mortality rates of deliberate and accidental overdoses. PMID:26781508

    The superior properties of natural rubber (cis-1,4-polyisoprene [NR]) are a function of its structure and composition, properties that still remain a mystery and that are irreplaceable by any synthetic rubber. NR from guayule (Parthenium argentatum) has been gaining special interest for its hypoallergenic properties while maintaining superior mechanical properties that are commonly associated with the Brazilian rubber tree (Hevea brasiliensis), the most common source of NR. Techniques exist to isolate washed rubber particles (WRPs) that contain enzymatically active rubber transferase, to study NR biosynthesis, and previous work on the in vitroNRgrowth in Hevea has demonstrated the presence of around 50wt%of a low molecular weight ([MW], Mn <10 000 g/mol) fraction. Structural and compositional analyses of this low MW fraction in Hevea are challenging due to the high protein content. Here, we discuss the analysis and composition of guayule latex and WRPs using high-resolution Size Exclusion Chromatography. We also discuss the composition of the soluble fraction of inactive guayule latex using matrix-assisted laser desorption ionization/time of flight mass spectrometry.

  10. From Antarctica or Asia? New colonization scenario for Australian-New Guinean narrow mouth toads suggested from the findings on a mysterious genus Gastrophrynoides

    Directory of Open Access Journals (Sweden)

    Ahmad Norhayati

    2011-06-01

    Full Text Available Abstract Background Microhylidae is a geographically widespread family of anurans. Although several extensive molecular analyses have attempted to elucidate their subfamilial relationships, and correlate these with Mesozoic and Cenozoic continental drifts, consensus has not been reached. Further, generic level relationships have not been well investigated in some microhylid subfamilies, and therefore subfamilial affiliations of some genera are still unclear. To elucidate the phylogenetic positions of two mysterious Asian genera, Gastrophrynoides and Phrynella, and to better understand the trans-continental distributions of microhylid taxa, we performed molecular phylogenetic and dating analyses using the largest molecular dataset applied to these taxa to date. Results Six nuclear and two mitochondrial genes (approx. 8 kbp were sequenced from 22 microhylid frog species representing eight subfamilies. The maximum likelihood and Bayesian analyses could not fully elucidate the subfamilial relationships, suggesting a rapid radiation of these taxa between 85 and 66 million years ago. In contrast, generic relationships of Asian microhylines were generally well resolved. Conclusion Our results clearly showed that one of two problematic Asian genera, Phrynella, was nested in the clade of the Asian subfamily Microhylinae. By contrast, Gastrophrynoides occupied the most basal position of the Australian-New Guinean subfamily Asterophryinae. The estimated divergence of Gastrophrynoides from other asterophryine was unexpectedly around 48 million years ago. Although a colonization scenario via Antarctica to the Australian-New Guinean landmass has been suggested for Asterophryinae, our finding suggested a novel colonization route via Indo-Eurasia.

  11. A Discovered Ducal Seal Does Not Belong to the Incorporation Charter for the City of Krakow Solving the Mystery Using Genetic Methods.

    Science.gov (United States)

    Lech, Tomasz

    2016-01-01

    The Incorporation Charter for the city of Krakow, the former capital of Poland, is one of the most valuable documents stored in the National Archives in Krakow. The document, which was written in 1257 on parchment, grants Krakow the Magdeburg rights and regulates its legal, statutory, economic and settlement-related aspects. The Charter was placed in the National Register of the Memory of the World UNESCO programme in 2014. A ducal seal, considered to be the lost seal detached from the Incorporation Charter, was found in the sphragistic collection after nearly 500 years. Unfortunately, it was uncertain whether the seal in question was indeed the missing part of the document. The aim of the study presented below was to solve this mystery. For this purpose, the parchment on which the Incorporation Charter was written was compared with the fragment of the parchment attached to the discovered seal. The study involved the analysis of selected mitochondrial DNA sequences and additional analysis at the level of nuclear DNA using microsatellite markers in the form of 11 STR (Short Tandem Repeat) loci, to identify the species and individual whose skin had been used to make the parchment. This analysis revealed that seal and parchment was from different individuals and thereby discovered that the seal was never a part of the Incorporation Charter. The study is further an example of informative DNA preservation in cultural heritage objects.

  12. Von Economo Neurons and Fork Cells: A Neurochemical Signature Linked to Monoaminergic Function.

    Science.gov (United States)

    Dijkstra, Anke A; Lin, Li-Chun; Nana, Alissa L; Gaus, Stephanie E; Seeley, William W

    2018-01-01

    The human anterior cingulate and frontoinsular cortices are distinguished by 2 unique Layer 5 neuronal morphotypes, the von Economo neurons (VENs) and fork cells, whose biological identity remains mysterious. Insights could impact research on diverse neuropsychiatric diseases to which these cells have been linked. Here, we leveraged the Allen Brain Atlas to evaluate mRNA expression of 176 neurotransmitter-related genes and identified vesicular monoamine transporter 2 (VMAT2), gamma-aminobutyric acid (GABA) receptor subunit θ (GABRQ), and adrenoreceptor α-1A (ADRA1A) expression in human VENs, fork cells, and a minority of neighboring Layer 5 neurons. We confirmed these results using immunohistochemistry or in situ hybridization. VMAT2 and GABRQ expression was absent in mouse cerebral cortex. Although VMAT2 is known to package monoamines into synaptic vesicles, in VENs and fork cells its expression occurs in the absence of monoamine-synthesizing enzymes or reuptake transporters. Thus, VENs and fork cells may possess a novel, uncharacterized mode of cortical monoaminergic function that distinguishes them from most other mammalian Layer 5 neurons. © The Author 2016.

  13. LinkED: A Novel Methodology for Publishing Linked Enterprise Data

    Directory of Open Access Journals (Sweden)

    Shreyas Suresh Rao

    2017-01-01

    Full Text Available Semantic Web technologies have redefined and strengthened the Enterprise-Web interoperability over the last decade. Linked Open Data (LOD refers to a set of best practices that empower enterprises to publish and interlink their data using existing ontologies on the World Wide Web. Current research in LOD focuses on expert search, the creation of unified information space and augmentation of core data from an enterprise context. However, existing approaches for publication of enterprise data as LOD are domain-specific, ad-hoc and suffer from lack of uniform representation across domains. The paper proposes a novel methodology called LinkED that contributes towards LOD literature in two ways: (a streamlines the publishing process through five stages of cleaning, triplification, interlinking, storage and visualization; (b addresses the latest challenges in LOD publication, namely: inadequate links, inconsistencies in the quality of the dataset and replicability of the LOD publication process. Further, the methodology is demonstrated via the publication of digital repository data as LOD in a university setting, which is evaluated based on two semantic standards: Five-Star model and data quality metrics. Overall, the paper provides a generic LOD publication process that is applicable across various domains such as healthcare, e-governance, banking, and tourism, to name a few.

    Full Text Available Keratoconus is a common ectatic disorder occurring in more than 1 in 1,000 individuals. The condition typically starts in adolescence and early adulthood. It is a disease with an uncertain cause and its progression is unpredictable, but in extreme cases, vision deteriorates and can require corneal transplant surgery. Corneal collagen cross-linking (CCL with riboflavin (C3R is a recent treatment option that can enhance the rigidity of the cornea and prevent disease progression. Since its inception, the procedure has evolved with newer instrumentation, surgical techniques, and is also now performed for expanded indications other than keratoconus. With increasing experience, newer guidelines regarding optimization of patient selection, the spectrum of complications and their management, and combination procedures are being described. This article in conjunction with the others in this issue, will try and explore the uses of collagen cross-linking (CXL in its current form.

  17. Using turbocodes on optical links

    Directory of Open Access Journals (Sweden)

    Glenn Claes

    2006-04-01

    Full Text Available The fast evolving telecommunication world is permanently in search for faster and better communication links. On one hand, turbo codes are like a dream come true. Due to their amazing performance, they have become the reference in the word of error detecting and correcting codes. On the other hand, broadband transmission channels like optical fibres can meet the need for higher transmission velocity. In this paper therefore we will bring these two elements together and thus the performance of turbocodes on optical links will be studied. First the turbocode will be optimised throughout an individual analysis of each of its design parameters. Moreover it wil be shown that turbocodes have much better performance than the well known Reed-Solomon codes. Finally we will show that the 8Bit/10Bit code, which is required to comply with the Gigabit Ethernet standard, becomes superfluous when working with turbocodes. All tests were carried out on multimode graded-index glass fibres.

    It is often said that it is easier to learn what is observed and practiced on a daily basis; to the need to effectively link theory with practice considered in the process of teaching and learning, many strategies have been developed to allow this process to be carried out in a more efficiently maner. It is, therefore, very important to recognize that an appropriate teacher/student relationship is essential for students to acquire the skills and abilities required.

    Do you have a poor-performing employee on your medical practice team? If so, you're not alone. Unfortunately, this is a problem that many medical practice managers face. This article describes the best strategies for managing your team's weakest link. It explores common yet very difficult circumstances that cause low employee performance and that test the patience, heart, and skills of a practice manager. It guides readers through a process of self-discovery to determine whether their negative biases or grudges may be causing employees to perform poorly. It suggests several possible other reasons for weak employee performance, including problems with the job, practice, leadership, communication, and fit between the employee and the job. This article also suggests the best strategy for communicating concerns about performance to the weakest-link employee. It offers guidance to practice managers about protecting their time and energy when handling a poor performer. It provides a simple formula for calculating the cost of a low-performing employee, 10 possible personal reasons for the employee's poor work performance, specific questions to ask to uncover the reasons for poor performance, and an eight-rule strategy for confronting poor performance effectively. Finally, this article offers practice managers a practical strategy for handling resistance from their weakest link, illustrated with a sample dialogue.

  2. The wounded male persona and the mysterious feminine in the poetry of James Wright: a study in the transformation of the self.

    Science.gov (United States)

    Graves, M; Schermer, V L

    1998-12-01

    James Wright's work is multilayered. Taken as a whole, which Annie Wright's beautiful compilation, Above the River, allows one to do, Wright's poems (as well as his masterful "prose poems") have a pattern akin to a mythic cycle. "Mythemes" (Lévi-Strauss, 1979) recur as dialectic opposites from one poem to another, whether the abandoned male and mysterious woman, humankind and nature, blindness and seeing, secrets and revelation. Suggestive and symbolic forms such as birds, horses, earth, sky, the destitute, rivers, and adolescence weave themselves throughout in inner and outer "landscapes" of images and experiential moments. There is a frequent shift of "gestalts" between the inner world and external reality. Such a "blooming, buzzing confusion" of internal and external referents might appear to be psychotic and imply a loss of "reality testing." Chassaguet-Smirgel (1988), citing Oscar Wilde's The Picture of Dorian Gray as an example, contended that the artist narrowly averts psychosis by transforming it into a work of art. Surrealists, for whom the psychoanalyst Jacques Lacan was an important figure (cf. Sarup, 1992, pp. 17-27), elevated psychosis to the status of art, and Wright has been considered to be a surrealistic poet, although he himself denied such an affiliation. Hall (Wright, 1990, Introduction, pp. xxiii-xxxvii) suggests that Wright, in addition to an extensive history of alcoholism, from which he seemed to recover towards the end of his life, suffered from a major mental illness, which included episodes of severe depression, hospitalizations, and at least one suicide attempt. The severity of the asceticism and the extreme damage to the self in some Wright's work suggests their roots in early traumatic experiences. (A terribly damaged yet heroic personage, whose disfigurement perhaps symbolizes the poet's trauma, is "Hook" [ATR, pp. 315-316], about a man who gives his last few cents to the poet with a hook replacing his amputated hand.) Not enough is

  4. Current practice of usual clinic blood pressure measurement in people with and without diabetes: a survey and prospective 'mystery shopper' study in UK primary care.

    Stevens, Sarah L; McManus, Richard J; Stevens, Richard John

    2018-04-12

    Hypertension trials and epidemiological studies use multiple clinic blood pressure (BP) measurements at each visit. Repeat measurement is also recommended in international guidance; however, little is known about how BP is measured routinely. This is important for individual patient management and because routinely recorded readings form part of research databases. We aimed to determine the current practice of BP measurement during routine general practice appointments. (1) An online cross-sectional survey and (2) a prospective 'mystery shopper' study where patients agreed to report how BP was measured during their next appointment. Primary care. Patient charity/involvement group members completing an online survey between July 2015 and January 2016. 334 participants completed the prospective study (51.5% male, mean age=59.3 years) of which 279 (83.5%) had diabetes. Proportion of patients having BP measured according to guidelines. 217 participants with (183) and without diabetes (34) had their BP measured at their last appointment. BP was measured in line with UK guidance in 63.7% and 60.0% of participants with and without diabetes, respectively. Initial pressures were significantly higher in those who had their BP measured more than once compared with only once (p=0.016/0.089 systolic and p<0.001/p=0.022 diastolic, in patients with/without diabetes, respectively). Current practice of routine BP measurement in UK primary care is often concordant with guidelines for repeat measurement. Further studies are required to confirm findings in broader populations, to confirm when a third repeat reading is obtained routinely and to assess adherence to other aspects of BP measurement guidance. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  5. ON IRON MONOXIDE NANOPARTICLES AS A CARRIER OF THE MYSTERIOUS 21 μm EMISSION FEATURE IN POST-ASYMPTOTIC GIANT BRANCH STARS

    International Nuclear Information System (INIS)

    Li, Aigen; Jiang, B. W.; Liu, J. M.

    2013-01-01

    A prominent mysterious emission feature peaking at ∼20.1 μm—historically known as the '21 μm' feature—is seen in over two dozen Galactic and Magellanic Cloud carbon-rich, post-asymptotic giant branch (post-AGB) stars. The nature of its carrier remains unknown since the first detection of the 21 μm feature in 1989. Over a dozen materials have been suggested as possible carrier candidates. However, none of them has been accepted: they either require too much material (compared to what is available in the circumstellar shells around these post-AGB stars), or exhibit additional emission features that are not seen in these 21 μm sources. Recently, iron monoxide (FeO) nanoparticles seem to be a promising carrier candidate as Fe is an abundant element and FeO emits exclusively at ∼21 μm. In this work, using the proto-typical protoplanetary nebula HD 56126 as a test case, we examine FeO nanoparticles as a carrier for the 21 μm feature by modeling their infrared emission, with FeO being stochastically heated by single stellar photons. We find that FeO emits too broad a 21 μm feature to explain that observed and the Fe abundance required to be locked up in FeO exceeds what is available in HD 56126. We therefore conclude that FeO nanoparticles are not likely to be responsible for the 21 μm feature

    In march 1994 the Central Planning Bureau (CPB) in the Hague, the National Institute of Public Health and Environmental Protection (RIVM) in Bilthoven and the Institute of Environmental Studies (IES) in Amsterdam started the first phase of a joint research program aimed at creating integrated scenarios of the global economy, GHG emissions, and climate impacts. The goal of the first phase of this project was to design and test a linked version of the economic model WORLD SCAN of the former, and the climate model IMAGE 2 of the latter institute. This first phase has resulted in the planned test runs with an operational version of the linked models by May 1995. The experiences in the first year were encouraging, both in the scientific and the organizational sense. In a sense, a link was made between scientific disciplines: a coupling of disciplines concerning with global economic development and the global physical climate system is difficult and novel. The goal of the project was to integrate long-term economic developments and effects of climate change. Both the WORLD SCAN model and IMAGE 2 provide a consistent analysis of the global system, but from different perspectives. IMAGE 2 simulates climate change and its effects in a global context but treats the economic system as exogenous. WORLD SCAN covers the world economic system in a consistent manner but does not take into account the global environment. The links are constructed in the area of agriculture and energy. The basic idea is that WORLD SCAN determines demand and supply on economic principles, while IMAGE 2 provides information on changes of land area and average quality of productive land, and other damage costs based on its three sub-systems. The demand for energy is fed into IMAGE 2's Energy Industry subsystem (EIS), which in turn determines emissions of greenhouse gases. Furthermore, some additional output from WORLD SCAN on activity levels, prices and capital structure can be used to determine

    Alport syndrome (AS) is a type IV collagen hereditary disease characterized by the association of progressive hematuric nephritis, hearing loss, and, frequently, ocular changes. Mutations in the COL4A5 collagen gene are responsible for the more common X-linked dominant form of the disease....... Considerable allelic heterogeneity has been observed. A "European Community Alport Syndrome Concerted Action" has been established to delineate accurately the AS phenotype and to determine genotype-phenotype correlations in a large number of families. Data concerning 329 families, 250 of them with an X...

In particular, we consider the case when the underlying data structure is a linked...... list, and the testing algorithm is allowed to either sample randomly from the list, or walk to nodes that are adjacent to those already visited. We study the well-known monotonicity testing problem in this model, and show that (n13) queries are both necessary and sufficient to distinguish whether...... a list is sorted (monotone increasing) versus a constant distance from sorted. Our bound is strictly greater than the (logn) queries required in the standard testing model, that allows element access indexed by rank, and strictly less than the (n12) queries required by a weak model that only allows...

    Cortical brain areas and dynamics evolved to organize motor behavior in our three-dimensional environment also support more general human cognitive processes. Yet traditional brain imaging paradigms typically allow and record only minimal participant behavior, then reduce the recorded data to single map features of averaged responses. To more fully investigate the complex links between distributed brain dynamics and motivated natural behavior, we propose the development of wearable mobile brain/body imaging (MoBI) systems that continuously capture the wearer's high-density electrical brain and muscle signals, three-dimensional body movements, audiovisual scene and point of regard, plus new data-driven analysis methods to model their interrelationships. The new imaging modality should allow new insights into how spatially distributed brain dynamics support natural human cognition and agency.

    In the general causative chain: radiation physics-radiation chemistry - radiobiology - cancer treatment, physics, the initiating and therefore cardinal agent, continues to play the role of the poor relation. The main reason for this state of affairs rests with the fact that most models of radiation action - the actual link between physics and biology - make very little or no use of information concerning the radiation field: they are simply convenient vehicles for describing a large body of radiobiological data with analytical expressions containing a minimum number of parameters. In spite of their practical usefulness such models will not be further considered here. It is a reasonable assertion that the main goal of radiation biophysics is to elucidate the mechanisms of radiation action on biological entities

    The high costs to develop, launch and maintain a satellite network makes protecting the assets imperative. Attacks may be passive such as eavesdropping on the payload data. More serious threat are active attacks that try to gain control of the satellite, which may lead to the total lost of the satellite asset. To counter these threats, new satellite and ground systems are using cryptographic technologies to provide a range of services: confidentiality, entity & message authentication, and data integrity. Additionally, key management cryptographic services are required to support these services. This paper describes the key points of current satellite control and operations, that are authentication of the access to the satellite TMTC link and encryption of security relevant TM/TC data. For payload data management the key points are multi-user ground station access and high data rates both requiring frequent updates and uploads of keys with the corresponding key management methods. For secure satellite management authentication & key negotiation algorithms as HMAC-RIPEMD160, EC- DSA and EC-DH are used. Encryption of data uses algorithms as IDEA, AES, Triple-DES, or other. A channel coding and encryption unit for payload data provides download data rates up to Nx250 Mbps. The presented concepts are based on our experience and heritage of the security systems for all German MOD satellite projects (SATCOMBw2, SAR-Lupe multi- satellite system and German-French SAR-Lupe-Helios- II systems inter-operability) as well as for further international (KOMPSAT-II Payload data link system) and ESA activities (TMTC security and GMES).

  5. Intermittent thermal plasma acceleration linked to sporadic motions of the magnetopause, first Cluster results

    Directory of Open Access Journals (Sweden)

    J.-A. Sauvaud

    Full Text Available This paper presents the first observations with Cluster of a very dense population of thermal ionospheric ions (H+, He+, O+ locally "accelerated" perpendicularly to the local magnetic field in a region adjacent to the magnetopause and on its magnetospheric side. The observation periods follow a long period of very weak magnetic activity. Recurrent motions of the magnetopause are, in the presented cases, unexpectedly associated with the appearance inside closed field lines of recurrent energy structures of ionospheric ions with energies in the 5 eV to  ~1000 eV range. The heaviest ions were detected with the highest energies. Here, the ion behaviour is interpreted as resulting from local electric field enhancements/decreases which adiabatically enhance/lower the bulk energy of a local dense thermal ion population. This drift effect, which is directly linked to magnetopause motions caused by pressure changes, allows for the thermal ions to overcome the satellite potential and be detected by the suprathermal CIS Cluster experiment. When fast flowing, i.e. when detectable, the density (~ 1 cm-3 of these ions from a terrestrial origin is (in the cases presented here largely higher than the local density of ions from magnetospheric/plasma sheet origin which poses again the question of the relative importance of solar and ionospheric sources for the magnetospheric plasma even during very quiet magnetic conditions.

    Tout, Christopher A.

    We pay tribute to the memory of Manuel Forestini by recalling his contributions to astronomy and in particular to our understanding of AGB stars. We critically examine the current status of this understanding amongst the community and deduce that major uncertainties arise in the physics of convection, any form of extra mixing beyond convection and the mass loss from the stellar surface. Coupled with these are numerical difficulties associated with the short and similar timescales for structural changes, nuclear burning and convective mixing. We hope that workshops such as this will promote familiarity amongst our diverse international community young and old and so promote effective dialogue that will ultimately lead to solutions to our problems along with the creation of new ones for the future!

(AECL); AECL expand its research and development activities, including non-nuclear R and D; AECL be allowed to hold a minority interest in any component of AECL that is privatized; any new entity created by privatization from AECL be required to remain under Canadian control; the Atomic Energy Control Act be altered to allow the Atomic Energy Control Board (AECB) to recover costs through licensing fees and user charges, while the AECB's parliamentary appropriation is increased to offset remaining costs of operations; membership on the AECB be increased from one to five full-time members, retaining the present four part-time members; the AECB hold its hearings in public; the name of the AECB be changed so it is more readily distinguishable from AECL; the AECB establish an office of public information; and that federal and provincial governments cooperate more closely to identify opportunities where more efficient use of electricity could be achieved and to promote those measures that can attain the greatest economic efficiency

  12. Does medical mystery threaten biotech

    Raphals, P.

    1990-11-02

    A puzzling medical syndrome caused by substances grown in a genetically engineered bacterium could have profound consequences for the entire biotechnology industry-if Jeremy Rifkin has his way. Rifkin, the controversial biotech critic, has filed a petition based on the eosinophilia-myalgia syndrome (EMS) with the Food and Drug Administration. In it, he asks that the FDA's review of all products made by genetic engineering techniques be suspended until strict new rules are in place to protect the public. The problem is that no one yet knows whether the specific contaminant that has caused up to 5000 EMS cases and 27 deaths was actually the result of genetic engineering. It might well have been the result of problems with chemical purification steps that have little to do with molecular genetics. Until now there has been no way to resolve that uncertainty. But help is on the way-in the form of a recently published animal model of the disease that should eventually enable researchers to pinpoint the precise cause of the syndrome.

    2015-01-01

    As only 0.5 per cent (the shining part) of the Universe is seen by telescopes, and corresponds to a tenth of ordinary matter or 5 per cent of the cosmos, astrophysicists postulated that the remaining 95 per cent are made of dark matter and dark energy. But always more researchers put the existence of this dark matter and energy into question again. They notably think of giving up Newton's law of universal gravitation, and also the basic assumption of cosmology, i.e. the homogeneous character of the Universe. The article recalls the emergence of the notion of dark matter to explain the fact that stars stay within a galaxy, whereas with their observed speed and the application of the gravitational theory they should escape their galaxy. Then, the issue has been to find evidence of the existence of dark matter. Neutrinos were supposed to be a clue, but only for a while. The notion of dark energy was introduced more recently by researchers who, by the observation of supernovae, noticed that the Universe expansion was accelerated in time. Then, after having discussed the issues raised by the possible existence of dark energy, the article explains how and why a new non homogeneous cosmology emerged. It also evokes current and future researches in this field. In an interview, an astrophysicist outlines why we should dare to modify Newton's law

    Over the first 50 years of its existence, before digital photography became the norm, CERN accumulated about a quarter of a million hard-copy images in its archive. Now, a project is underway to digitise the entire collection and make it searchable via the CERN Document Server (CDS).   Some 120,000 black and white images from the period 1955-1985 are currently being digitised, with files being uploaded in batches of several hundred per week. They are then automatically sorted into albums based on the existing information. In most cases, at least some descriptions exist, allowing us to identify the pictures. However, many albums are still in need of titles, the names of the people in the photos, descriptions of equipment, etc., and we believe that much of this information could be crowd-sourced from the CERN community.

  1. [Mystery and problems of cloning].

    Nikitin, V A

    2010-01-01

    The attention of investigators is attracted to the fact that, in spite of great efforts in mammalian cloning, advances that have been made in this area of research are not great, and cloned animals have developmental pathologies often incompatible with life and/or reproduction ability. It is yet not clear what technical or biological factors underlie this, and how they are connected or interact with each other, which is more realistic strategically. There is a great number of articles dealing with the influence of cloning with the nuclear transfer on genetic and epigenetic reprogramming of donor cells. At the same time we can see the practical absence of analytical investigations concerning the technology of cloning as such, its weak points, and possible sources of cellular trauma in the course of microsurgery of nuclear transfer or twinning. This article discusses step by step several nuclear transfer techniques and the methods of dividing early preimplanted embryos for twinning with the aim to reveal possible sources of cell damage during micromanipulation that may have negative influence on the development of cloned organisms. Several new author's technologies based on the study of cell biophysical characteristics are described, which allow one to avoid cellular trauma during manipulation and minimize the possibility of cell damage at any rate.

  3. The mysteries of remote memory

    Science.gov (United States)

    2018-01-01

    Long-lasting memories form the basis of our identity as individuals and lie central in shaping future behaviours that guide survival. Surprisingly, however, our current knowledge of how such memories are stored in the brain and retrieved, as well as the dynamics of the circuits involved, remains scarce despite seminal technical and experimental breakthroughs in recent years. Traditionally, it has been proposed that, over time, information initially learnt in the hippocampus is stored in distributed cortical networks. This process—the standard theory of memory consolidation—would stabilize the newly encoded information into a lasting memory, become independent of the hippocampus, and remain essentially unmodifiable throughout the lifetime of the individual. In recent years, several pieces of evidence have started to challenge this view and indicate that long-lasting memories might already ab ovo be encoded, and subsequently stored in distributed cortical networks, akin to the multiple trace theory of memory consolidation. In this review, we summarize these recent findings and attempt to identify the biologically plausible mechanisms based on which a contextual memory becomes remote by integrating different levels of analysis: from neural circuits to cell ensembles across synaptic remodelling and epigenetic modifications. From these studies, remote memory formation and maintenance appear to occur through a multi-trace, dynamic and integrative cellular process ranging from the synapse to the nucleus, and represent an exciting field of research primed to change quickly as new experimental evidence emerges.

  4. The mysterious SU UMa stars

    Charles, P.A.

    1990-01-01

    This paper discusses the characteristics and the source of energy of the explosive stars called cataclysmic variables (CVs), with special attention given to the SU UMa stars, which represent CVs which have disks. In SU UMa binaries, a gas stream from a cool reddish star hits an accretion disk spiraling around a white dwarf. The impact of the stream produces a bright 'hot spot' on the edge of the disk, seen only when the system is quiescent and the disk is relatively dim (during outbursts, the hot spot is swamped by the light of the disk itself). The principal source of energy and light of most CVs is the gravitational potential energy released by matter falling from the dim reddish companion onto the white dwarf. The mechanism involved in the overflow of the reddish star is believed to be magnetic braking. Simulations are presented that explain the SU UMa phenomena and which may be applicable to other high-mass-ratio interacting binaries

    Predicting missing links in incomplete complex networks efficiently and accurately is still a challenging problem. The recently proposed Cannistrai-Alanis-Ravai (CAR) index shows the power of local link/triangle information in improving link-prediction accuracy. Inspired by the idea of employing local link/triangle information, we propose a new similarity index with more local structure information. In our method, local link/triangle structure information can be conveyed by clustering coefficient of common-neighbors directly. The reason why clustering coefficient has good effectiveness in estimating the contribution of a common-neighbor is that it employs links existing between neighbors of a common-neighbor and these links have the same structural position with the candidate link to this common-neighbor. In our experiments, three estimators: precision, AUP and AUC are used to evaluate the accuracy of link prediction algorithms. Experimental results on ten tested networks drawn from various fields show that our new index is more effective in predicting missing links than CAR index, especially for networks with low correlation between number of common-neighbors and number of links between common-neighbors.

  9. Hacking 360 Link: A hybrid approach

    Full Text Available When the University of Victoria Libraries switched from a locally-hosted link resolver (SFX to a vendor-hosted link resolver (360Link, new strategies were required to effectively integrate the vendor-hosted link resolver with the Libraries' other systems and services. Custom javascript is used to add links to the 360Link page; these links then point at local PHP code running on UVic servers, which can then redirect to appropriate local service or display a form directly. An open source PHP OpenURL parser class is announced. Consideration is given to the importance of maintaining open protocols and standards in the transition to vendor-hosted services.

We demonstrate that numerous diversity measures satisfying all the desirable criteria mentioned by Patil and Taillie can be defined by the generating functions of certain disparities and the associated residual adjustment functions. This provides the statistician and the ecologist a wide class of flexible indices for the statistical measurement of diversity.

  11. Materializing the web of linked data

    CERN Document Server

    Konstantinou, Nikolaos

    2015-01-01

    This book explains the Linked Data domain by adopting a bottom-up approach: it introduces the fundamental Semantic Web technologies and building blocks, which are then combined into methodologies and end-to-end examples for publishing datasets as Linked Data, and use cases that harness scholarly information and sensor data. It presents how Linked Data is used for web-scale data integration, information management and search. Special emphasis is given to the publication of Linked Data from relational databases as well as from real-time sensor data streams. The authors also trace the transformation from the document-based World Wide Web into a Web of Data. Materializing the Web of Linked Data is addressed to researchers and professionals studying software technologies, tools and approaches that drive the Linked Data ecosystem, and the Web in general.

    Two complementary de facto standards for the publication of electronic documents are HTML on theWorldWideWeb and Adobe s PDF (Portable Document Format) language for use with Acrobat viewers. Both these formats provide support for hypertext features to be embedded within documents. We present a method, which allows links and other hypertext material to be kept in an abstract form in separate link databases. The links can then be interpreted or compiled at any stage and applied, in the correct ...

    Cascading failure is an important process which has been widely used to model catastrophic events such as blackouts and financial crisis in real systems. However, so far most of the studies in the literature focus on the cascading process on nodes, leaving the possibility of link cascade overlooked. In many real cases, the catastrophic events are actually formed by the successive disappearance of links. Examples exist in the financial systems where the firms and banks (i.e. nodes) still exist but many financial trades (i.e. links) are gone during the crisis, and the air transportation systems where the airports (i.e. nodes) are still functional but many airlines (i.e. links) stop operating during bad weather. In this letter, we develop a link cascade model in complex networks. With this model, we find that both artificial and real networks tend to collapse even if a few links are initially attacked. However, the link cascading process can be effectively terminated by setting a few strong nodes in the network which do not respond to any link reduction. Finally, a simulated annealing algorithm is used to optimize the location of these strong nodes, which significantly improves the robustness of the networks against the link cascade. - Highlights: • We propose a link cascade model in complex networks. • Both artificial and real networks tend to collapse even if a few links are initially attacked. • The link cascading process can be effectively terminated by setting a few strong nodes. • A simulated annealing algorithm is used to optimize the location of these strong nodes.

    Full Text Available In Nicaragua levels Linking state, university and business are low, Nicaraguan universities have initiated communication strategies with the state and the private sector. The idiosyncrasies of its citizens favor this link. The entailment policies formalize the communications and information networks. Universities have a key role in building models and organizations that provide alternatives to economic development. Linking the university with the environment, generating virtuous circles, where companies achieve greater competitiveness, the state, higher taxes and public stability, universities generate new knowledge. This article analyzes the strategies linking U-E- E that can be applied in Nicaragua, to strengthen and achieve positive developments in the country.

  18. S-LINK, a data link interface specification for the LHC era

    International Nuclear Information System (INIS)

    Bij, H.C. van der; McLaren, R.A.; Boyle, O.

    1996-01-01

    In the Technical Proposals for ATLAS, CMS and ALICE there is a requirement for several thousand data links. Although there is an obvious need for standardization, this seems difficult to achieve as the links run at different speeds, over different distances and have various constraints of power consumption, size and radiation hardness. An additional complication is that today we cannot decide which will be the most cost effective technology for the implementation of the final links. Furthermore, we must allow designers of boards at each end of the link, for example readout electronics and input buffers, to work in parallel with the development of the links. The S-LINK is a new concept which should provide the benefits of standardization without the limitations. The S-LINK specification defines, at both ends of the link, a simple FIFO-like user interface which remains independent of the technology used to implement the physical link. The physical link provides transfer of event data and control words, error detection, optional flow control and test facilities. This paper describes the S-LINK specification and gives examples of the use of the S-LINK, the physical links being designed, and the test equipment that is being developed

  19. Radiation-induced linking reactions in polyethylene

    Zoepfl, F.J.

    1983-01-01

    Three types of measurements are reported relating to chemical reactions in polyethylene induced by ionizing radiation: 1) viscometric and low-angle laser light scattering measurements to determine the effect of a radical scavenger on the yield of links; 2) calorimetric measurements to determine the effect of radiation-induced linking on the melting behavior of polyethylene; and 3) high-resolution solution carbon 13 nuclear magnetic resonance (NMR) spectrometry measurements to determine the nature of the links and the method of their formation. The NMR results present the first direct detection of radiation-induced long-chain branching (Y links) in polyethylene, and place an apparent upper limit on the yield of H-shaped crosslinks that are formed when polyethylene is irradiated to low absorbed doses. The effect of radiation-induced linking on the melting behavior of polyethylene was examined using differential scanning calorimetry (DSC). It was found that radiation-induced links do not change the heat of fusion of polythylene crystals, but decrease the melt entropy and increase the fold surface free energy per unit area of the crystals. The carbon 13 NMR results demonstrate that long-chain branches (Y links) are formed much more frequently than H-shaped crosslinks at low absorbed doses. The Y links are produced by reactions of alkyl free radicals with terminal vinyl groups in polyethylene
