Sample records for soft news production

  1. Soft computing and electronic product engineering

    1997-10-01

    The methodologies of soft computing (fuzzy logic, neural networks, evolutionary computation, etc.), represent a new computational paradigm which may usefully complement the conventional digital computing approaches in the application to real life problems. This paper considers the potential role of soft computing (SC) in electronic product engineering. The problem is first treated on general grounds, using electronic design as example. Then a more specific discussion is presented, concerning the use of SC methodologies (fuzzy logic and neural nets) in a representative problem of testing, the analysis and interpretation of infrared thermal maps.

  2. Dependencies between soft proofing and prepress production

    In order to save time and money, more and more printing organizations are investing in on-line customer portals to allow uploading content and giving formal approvals based on soft proofs before the final production process (plate making and printing) can be initiated. The approvals are typically made on soft proofs of pages whereas, obviously, the images used for plate making are so-called imposed flats (a combination of pages rotated in such a way that the printed matter can be obtained after folding and cutting). The main goal of a soft proof of a page is to simulate accurately on a display device how the page will be finally printed. The quality expectations of a soft proof are very high since a formal approval implies contractual obligations from the printing organization. This quality, however, can be influenced by many parameters. By definition, soft proofs will be displayed on a monitor (being a light emitting device), whereas a print on paper can only be seen as the reflection of a light source. As a consequence, monitors can be described by an additive color model whereas printers or presses will be modeled by a subtractive color model. Other differences relate to how the image is generated: presses can only output binary information (ink or no ink) and continuous tones are simulated by using screening techniques whereas, on a monitor, a multi-level signal can generate different shades of a specific color. The differences described above are addressed by many color management systems available on the market today. An upcoming requirement in this area is that people do not only expect the color management software to behave well but also expect this software to validate its behavior. Another range of problems with soft proofs relates to the rendering (converting vector-based page data into bitmaps) and separation process. These can be divided in two classes: spatial issues (related to resolution differences, high-frequency patterns, aliasing problems etc.) and issues related to object layering (overprint and transparency issues). Also when optimizations are carried out for plate reuse across versioned products, many things can go wrong. In this paper, we will categorize the different potential problems occurring with soft proofs and examine in detail how these problems can be avoided. It will turn out that this can only be realized if one knows the details on how the printing plates will be generated in prepress production.

  6. Soft Gluon Effects in Supersymmetric Particle Production at the LHC

    Kulesza, A.; Motyka, L.

    2009-07-01

    We report on recent results A. Kulesza, L. Motyka, Phys. Rev. Lett. 102, 111802 (2009) on soft gluon effects in the production of squark-antisquark and gluino-gluino pairs at the LHC. The soft gluon corrections are resummed at the next-to-leading logarithmic (NLL) accuracy and matched with the known next-to-leading (NLO) order estimates of the cross-sections. The one-loop soft anomalous dimension matrices controlling the colour evolution of the gluino pair production are presented. We show that the resummation of soft gluon effects reduces substantially the theoretical uncertainty for gluino pair-production at the LHC.

  9. The Interaction of Production and Consumption in the News Media Social Space

    NASA Astrophysics Data System (ADS)

    Graham, Gary; Kerrigan, Finola; Mehmood, Rashid; Rahman, Mustafizur

    Newspapers are operating in increasingly competitive and fragmented markets for audiences and advertising revenues, government media policy and changing audience requirements for news and the ways in which it is presented and delivered. A growing army of bloggers and amateur citizen journalists now delivers - but rarely edits - content for all media platforms, while new media technologies, combined with the changing structure of global news industries, are radically changing the ways in which newspapers and media business functions and struggles for profitability. Our research sought to answer the question of how the internet is impacting on producer/consumer value activities in the news media supply chain. To answer this question initial descriptive statistical analysis was performed on 51 newspapers. This was followed by a focus group undertaken with London-based news media organizations and bloggers. The findings showed that in spite of initial fear and rejection, the internet is now firmly embedded in news media supply chain operations. Firms are now using the internet as an operant resource and working proactively with consumers to develop various forms of relationship value. We highlight the role of consumers in the creation of news (editorial) content and consumer-driven moves toward a merged media platform of distribution (including television, online, mobile and printed forms). Regional news media organizations will probably continue to survive if they are able to supply a highly specialized and 'hyper local' community service. This will be in the form of 'hybrid' content: analysis, interpretation and investigative reporting in a print product that appears less than daily combined with constant updating and reader interaction on the web.

    This cross-national comparative case study of online news production analyzes the strategies of Cable News Network (CNN) and the Norwegian Broadcasting Corporation (NRK), aiming at understanding of the implications of organizational strategy on the role of journalists, explains why traditional media organizations have a tendency to develop a multi-platform approach (distributing content on several platforms, such as television, online, mobile) rather than developing the cross-media (with interplay between media types) or multimedia approach anticipated by both scholars and practitioners.

    2009-02-25

    The method developed previously for the determination of bisphenol A (BPA) in liquid infant formula was adapted and validated for determination of BPA in soft drink products. This method was based on solid phase extraction and derivatization with acetic anhydride followed by gas chromatography-mass spectrometry in selected-ion monitoring mode. The average method detection limit was 0.045 microg/L for a 10 mL sample. The average extraction recoveries were 101 and 99.9% obtained with seven different soft drink products spiked with BPA at 0.5 and 2.5 microg/L, respectively. Good repeatability of the method was observed with replicate analyses of seven different soft drinks; relative standard deviations ranged from 1.3 to 6.6%. This method was used to analyze samples of 72 canned soft drink products for BPA. Except for three products from which BPA-d16 could not be recovered at all due to interference of product compositions (e.g., quinine hydrochloride in tonic water), BPA was detected in samples of all the other products at levels ranging from 0.032 to 4.5 microg/L. About 75% of the products had BPA levels of <0.5 microg/L, and 85% of the products had BPA levels of <1 microg/L. Exposure to BPA through consumption of canned soft drink products is low; dietary intake of BPA was estimated at 0.027 microg/kg of body weight/day on the basis of the consumption of one canned soft drink with the highest BPA level (4.5 microg/L) for an adult with a 60 kg body weight, well below the provisional tolerable daily intake of 25 microg/kg of body weight/day established by Health Canada.

  13. The two-loop soft function for heavy quark pair production at future linear colliders

    2015-08-01

    We report on the calculation of the threshold soft function for heavy quark pair production in e+e- annihilation at two-loop order. Our main result is a generalization of the familiar Drell-Yan threshold soft function to the case of nonzero primary quark mass. We set up a framework based on the method of differential equations which allows for the straightforward calculation of the bare soft function to arbitrarily high orders in the dimensional regularization parameter. Remarkably, we find that we can obtain the bare two-loop Drell-Yan soft function from the heavy quark soft function to the order in epsilon required for a two-loop calculation by making simple replacements. We expect that our results will be of use, both as an important input for precision physics calculations at linear colliders and, more formally, as a first step toward a better understanding of the connection between vacuum matrix elements of massive soft Wilson lines and vacuum matrix elements of massless soft Wilson lines.

    2016-01-01

    Date fruit based products are gaining popularity among the consumers in almost all date growing countries due to its added nutritional value. Therefore, novel products were developed by combining two types of foods i.e., soft ripened cheeses and date fruit syrups or date powder. This study is the first to report the surface mold-ripened cheese production with date syrup and date powder. Model cheeses were prepared from pasteurized milk inoculated with Streptococcus thermophilus, Penicillium camemberti and Geotrichum candidum. Date syrup-1, date syrup-2, date powder or the date mixture were added at the stage of curdling. Based on the kinetic growth of the microbial groups in all the treatments, there was no change in the growth of these in various date palm product. On the contrary It may be said that addition of the date fruit product supports their growth. After 35 days, the amounts of total poly phenols were 128.3 ± 1.01, 81.8 ± 1.11, 33.5 ± 2.19, 156.23 ± 1.27 mg GAE/100 g in the cheeses support with date syrup-1, date syrup-2, date powder or the date mixture, respectively. Antioxidant activity of date fruits ranged from 80.13 IC50 (date syrup-2) to 82.23 IC50 (date syrup-1). Based on the chemical characteristics and sensory analysis, the study results showed the potential for innovative application of date products for developing new functional dairy products as an ideal medium for the delivery of biological active compounds with beneficial health effects over.

  16. Higgs boson production via gluon fusion: Soft-gluon resummation including mass effects

    2016-01-01

    We analyze soft and collinear gluon resummation effects at the N3LL level for Standard Model Higgs boson production via gluon fusion g g ?H and the neutral scalar and pseudoscalar Higgs bosons of the minimal supersymmetric extension at the next-to-next-to-next-to-leading-log (N3LL ) and next-to-next-to-leading-log (NNLL) level, respectively. We introduce refinements in the treatment of quark mass effects and subleading collinear gluon effects within the resummation. Soft and collinear gluon resummation effects amount to up to about 5% beyond the fixed-order results for scalar and pseudoscalar Higgs boson production.

    2013-10-01

    The propagation of a high energy quark distrurbs the confining vacuum inducing the currents in Dirac sea. Since quarks possess electric charge, these induced vacuum currents act as a source of soft photon radiation. This can lead to the enhancement of the soft photon production above the expectations based on the charged hadron yields and the Low theorem. We illustrate the phenomenon by using the exactly soluble 1 + 1 dimensional massless Abelian gauge model that shares with QCD all of the ingredients involved in this mechanism: confinement, chiral symmetry breaking, axial anomaly, and the periodic ?-vacuum. We show that the propagating quark throughout the process of hadronization induces in the vacuum charged transition currents that lead to a strong resonant enhancement of the soft photon yield; the Low theorem however remains accurate in the limit of very soft momenta. We then construct on the basis of our result a simple phenomenological model and apply it to the soft photon production in the fragmentation of jets produced in Z0 decays. We find a qualitative agreement with the recent result from the DELPHI Collaboration.

    Bonocore, D.; Laenen, E.; Magnea, L.; Vernazza, L.; White, C. D.

    2015-03-01

    We perform a case study of the behaviour of gluon radiation beyond the soft approximation, using as an example the Drell-Yan production cross section at NNLO. We draw a careful distinction between the eikonal expansion, which is in powers of the soft gluon energies, and the expansion in powers of the threshold variable 1 - z, which involves important hard-collinear effects. Focusing on the contribution to the NNLO Drell-Yan K-factor arising from real-virtual interference, we use the method of regions to classify all relevant contributions up to next-to-leading power in the threshold expansion. With this method, we reproduce the exact two-loop result to the required accuracy, including z-independent non-logarithmic contributions, and we precisely identify the origin of the soft-collinear interference which breaks simple soft-gluon factorisation at next-to-eikonal level. Our results pave the way for the development of a general factorisation formula for next-to-leading-power threshold logarithms, and clarify the nature of loop corrections to a set of recently proposed next-to-soft theorems.

    We study the differential cross sections for electroweak gauge-boson and Higgs production at small and very small transverse-momentum qT. Large logarithms are resummed using soft-collinear effective theory. The collinear anomaly generates a non-perturbative scale q*, which protects the processes from receiving large long-distance hadronic contributions. A numerical comparison of our predictions with data on the transverse-momentum distribution in Z-boson production at the Tevatron and LHC is given.

    We present methods to compute higher orders in the threshold expansion for the one-loop production of a Higgs boson in association with two partons at hadron colliders. This process contributes to the N3LO Higgs production cross section beyond the soft-virtual approximation. We use reverse unitarity to expand the phase-space integrals in the small kinematic parameters and to reduce the coefficients of the expansion to a small set of master integrals. We describe two methods for the calculation of the master integrals. The first was introduced for the calculation of the soft triple-real radiation relevant to N3LO Higgs production. The second uses a particular factorization of the three body phase-space measure and the knowledge of the scaling properties of the integral itself. Our result is presented as a Laurent expansion in the dimensional regulator, although some of the master integrals are computed to all orders in this parameter.

    Micropatterning and microfabrication techniques have been widely used to pattern cells on surfaces and to have a deeper insight into many processes in cell biology such as cell adhesion and interactions with the surrounding environment. The aim of this study was the development of an easy and versatile technique for the in vitro production of arrays of functional cardiac and skeletal muscle myofibers using micropatterning techniques on soft substrates. Cardiomyocytes were used for the production of oriented cardiac myofibers whereas mouse muscle satellite cells for that of differentiated parallel myotubes. We performed micro-contact printing of extracellular matrix proteins on soft polyacrylamide-based hydrogels photopolymerized onto functionalized glass slides. Our methods proved to be simple, repeatable and effective in obtaining an extremely selective adhesion of both cardiomyocytes and satellite cells onto patterned soft hydrogel surfaces. Cardiomyocytes resulted in aligned cardiac myofibers able to exhibit a synchronous contractile activity after 2 days of culture. We demonstrated for the first time that murine satellite cells, cultured on a soft hydrogel substrate, fuse and form aligned myotubes after 7 days of culture. Immunofluorescence analyses confirmed correct expression of cell phenotype, differentiation markers and sarcomeric organization. These results were obtained in myotubes derived from satellite cells from both wild type and MDX mice which are research models for the study of muscle dystrophy. These arrays of both cardiac and skeletal muscle myofibers could be used as in vitro models for pharmacological screening tests or biological studies at the single fiber level. PMID:18987976

  7. Systematic studies of the centrality dependence of soft photon production in Au + Au collision with PHENIX

    2014-11-01

    Since the earliest days of Heavy Ion Physics thermal soft photon radiation emitted during the reaction had been theorized as a smoking gun signal for formation of a quark-gluon plasma and as a tool to characterize its properties. In recent years the existence of excess photon radiation in heavy ion collisions over the expectation from initial hard interactions has been confirmed at both RHIC and LHC energies by PHENIX and ALICE respectively. There the radiation has been found to exhibit elliptic flow v2 well above what can currently be reconciled with a picture of early emission from a plasma phase. During the 2007 and 2010 Au + Au runs PHENIX has measured a high purity sample of soft photons down to pT > 0.4 GeV / c using an external conversion method. We present recent systematic studies by PHENIX from that sample on the centrality dependence of the soft photon yield, and elliptic and triangular flow v2 and v3 in Au + Au collisions which fill in the experimental picture and enable discrimination of competing soft photon production scenarios.

    1986-01-01

    The fully differential cross section for photon-electron pair production is integrated numerically over phase space. Results are obtained for the astrophysically interesting case in which the interaction between an ultrarelativistic electron and a soft photon results in electron-positron pair production. The positron spectrum is a function of the energies of both the photon and the electron, as well as the angle of interaction. It is found that the energy at which the positron distribution peaks is inversely proportional to the photon energy and independent of the electron energy. The positron spectrum is integrated once more over initial electron energies for a power-law energy distribution of primary electrons. The same procedure is repeated for the recoil particle; it is shown that the peak of the recoil energy distribution depends linearly on the energy of the primary electron. Finally, semianalytical expressions are obtained for the energy losses of the primary electrons.

    An analysis of the direct soft photon production rate as a function of the parent jet characteristics is presented, based on hadronic events collected by the DELPHI experiment at LEP1. The dependences of the photon rates on the jet kinematic characteristics (momentum, mass, etc.) and on the jet charged, neutral and total hadron multiplicities are reported. Up to a scale factor of about four, which characterizes the overall value of the soft photon excess, a similarity of the observed soft photon behavior to that of the inner hadronic bremsstrahlung predictions is found for the momentum, mass, and jet charged multiplicity dependences. However for the dependence of the soft photon rate on the jet neutral and total hadron multiplicities a prominent difference is found for the observed soft photon signal as compared to the expected bremsstrahlung from final state hadrons. The observed linear increase of the soft photon production rate with the jet total hadron multiplicity and its strong dependence on the jet neutral multiplicity suggest that the rate is proportional to the number of quark pairs produced in the fragmentation process, with the neutral pairs being more effectively radiating than the charged ones.

    Exchange spring composites (hard-soft magnetic composites) are interesting for many applications such as rare-earth free permanent magnets and information storage. One key aspect is the figure of merit, the energy product, also called (BH)max. The system of study is a magnetic nano composite where each bilayer consists of a soft and hard magnetic material of total height of 22 nm. Using micromagnetic simulations we have investigated the influence of different ratios of the volume of the hard and soft layers on the energy product and the number of bilayer repetitions. Our findings indicate that the maximum energy product depends strongly on the volume ratio as well as on the number of repetitions. In addition we have studied the influence of different anisotropy contributions of the hard and soft magnetic layer on the energy product. Finally we have studied the influence of the interlayer exchange coupling on the energy product, which show that strong interlayer exchange coupling is necessary to reach a high energy product.

    Results obtained using a new technique for studying cell metabolism are presented. The technique, consisting in CO2 production monitoring, has been applied to Saccharomyces cerevisiae yeast cells. Also the cells were irradiated using the soft X-ray laser-plasma source at Rutherford Appleton Laboratory with the aim of producing a damage of metabolic processes at the wall level, responsible for fermentation, without great interference with respiration, taking place in mitochondria, and DNA activity. The source was calibrated with PIN diodes and X-ray spectrometers and used Teflon stripes as target, emitting X-rays at about 0.9 keV, with a very low penetration in biological material. X-ray doses delivered to the different cell compartments were calculated following a Lambert-Bouguet-Beer law. Immediately after irradiation, the damage to metabolic activity was measured again by monitoring CO2 production. Results showed a general reduction in gas production by irradiated samples, together with non-linear and non-monotone response to dose. There was also evidence of oscillations in cell metabolic activity and of X-ray induced changes in oscillation frequency.

    NASA Astrophysics Data System (ADS)

    2000-07-01

    When Mary took up her appointment in the Institute's Education Department in June 1997, she indicated that she wished to return to teaching in two or three years. We have just heard that in September she will be joining the staff of the Science Department at Camden Girls' School, London. Mary's departure from the Institute is a great loss to the Department, where she has worked tirelessly, and with great imagination, to support those who teach physics at all secondary levels - and at primary level too when the opportunity presented itself. She has made tremendous contributions to the careers side of the Department's work, supporting careers events, providing informal training for others willing to do the same, helping to develop new careers materials and identifying people whom the Institute could use as role models or as the subject of case studies in print or electronic publications. Mary has been equally happy and willing to support pupils, students and teachers, and has been a wonderful role model herself, coming from an industrial research background, training for teaching after a career break and willing and able to teach biology, chemistry and design technology as well as physics. Mary has also written and edited Phases virtually single-handed. We are delighted to hear that Mary will continue to support the department's work as one of its teacher `volunteers'. Ilya Eigenbrot We are pleased to report that Ilya Eigenbrot, who will be known to some through his work at the Royal Institution and his appearances at the Christmas Lectures in a technical support role, has agreed to give the IOP Schools (touring) Lecture next year. The subject will be Lasers and this will follow nicely on to Zbig's lecture this year. Resources (print) Physics on Course The tenth issue of the Institute's popular guide to higher education, Physics on Course 2001, will be published early in July and distributed to all schools and colleges in the United Kingdom and the Republic of Ireland. Its pages are brimming with useful information to help sixth-formers and college students who wish to study physics make the very important decision regarding their particular choice of course and university. Under the heading `Summary tables of physics courses' every university listed in the publication has a table which includes all the courses on offer, their entrance requirements, duration and the awards given. Another section of the book entitled `Departmental information' includes data on the teaching and assessment styles of the Physics Department, special facilities plus a contact name and address. These sections, together with an expanded set of case studies of recent students and various other interesting articles, make this publication a must for anyone who is considering studying physics at university. Copies of Physics on Course 2001 will be available from Leila Solomon, Education Department, Institute of Physics, 76 Portland Place, London, W1N 3DH. The Particle Physics Wallchart (PCET) This full-colour chart, with a set of Teachers Notes, was published recently. It has been developed by PCET with Professor Peter Kalmus acting as expert consultant. The cost of the chart and notes is £7.75 plus VAT and copies can be purchased from PCET, 27 Kirchen Road, London W13 0UD (fax: 020 8566 5120). Inspire II The second part of Inspire was published in the Spring. It is a highly visual, full-colour leaflet which can be used as a stand-alone item but which was designed to `nest' inside the first four-page spread which was distributed in February. The occupational areas for physicists covered in the second leaflet include the media/leisure, finance and engineering (at technician level) industries. The third of the intended four sheets will be published later this year. (Copies of Inspire II have been included in the Affiliated schools/colleges package; other schools/colleges will be sent copies on request.) Nanotechnology - a technical brief The Industrial Affairs Department of the Institute is working on a series of Technical Briefs to broaden the provision of physics information to Members. The first title in the series, `Nanotechnology', is due to be published last month. The aim of this new series is to provide technical updates on current applications of physics, targeted at the nonspecialist scientist and engineer. The emphasis will be on burgeoning areas of physics with potential application across several or many fields. `Nanotechnology', for example, will sketch the background to the field, indicate the current state of the art and give a realistic view on future developments. The target readers are Institute of Physics Members in general, not specialists in nanotechnology or related topics and, in this respect, the Briefs could be of great interest to teachers. They are free of charge to Members but £7.50 for non-members. To obtain a copy, contact Emma Woods on 020 7470 4927 or by e-mail (emma.woods@iop.org). Courses Physics Update: 8-10 July, University of York The information leaflet/booking form for this course was sent to schools and colleges at the beginning of this term. Lecture topics include Ultrasonic imaging, Chaos, and The search for extra-terrestrial intelligent life. There will be workshops on New activities from Salters Horners physics, Computer modelling in A2 physics and Misconceptions in the learning of forces. Further information and booking forms are available from Leila Solomon. The venues and dates of subsequent Update courses are: 8-10 December, Oxford University 31 March-2 April 2001, Malvern College 7-9 July 2001, Royal Holloway College, London Teaching Physics INSET Days Following successful pilot runs in the summer term last year and at IOP Congress, the Education Department is organizing four (possibly five) INSET days for those teaching physics at KS3 without a strong background in the subject. The recent dates in June were all fully booked. The programme will be basically same for all the events with an introductory talk Inspiring Your Pupils, followed by workshops on Forces, Electricity and Light designed to enhance participants' knowledge of physics and its applications and to improve their confidence in teaching that knowledge. At each venue there will be an opportunity to tour the facilities, meet the staff and to assess the potential for school visits or link activities. The fee including course materials, lunch and other refreshments is £25. Leaflets have been sent to schools in the localities but further copies will be sent on request. Places are limited and prompt booking is essential. Further courses are planned for the autumn term as follows: Explore@Bristol (4 October) and possibly London in November. Substantially similar events may be organized for those teaching physics at KS4 in the Spring term of 2001. Physics Discipline Network Workshop: 14/15 September, University of Leeds `Our assessment of students and the media's assessment of us!' is the focus of this two-day event. The network was established in 1994 to encourage debate and discussion of teaching and learning initiatives among university physicists. Over the past five years the annual workshops have attracted over 200 delegates from most of the UK university physics departments. This year's workshop looks set to get off to a lively start with Professor Paul Black questioning the typical format of university physics examinations. This will be followed by a session on `A question of chemistry - creative problems for critical thinkers' which it is hoped will prompt thinking about comparable approaches in physics. This is just the start of a full programme of presentations including grass roots innovative practices as well as lead speakers of national prominence. Attention will focus on schools, too, with an input on the Pupil Researcher Initiative as a way of promoting physics at school level. Further details of this event are available from Dr Ashley Clarke in the Department of Physics and Astronomy at the University of Leeds. Physics at Work Exhibition: 12-14 September, University of Cambridge The year 2000 Exhibition will be the 16th organized by Brenda Jennison. The exhibition will be held at the Cavendish Laboratory and further details can be obtained from Brenda at the University (tel: 01223 332888, fax: 01223 332894 or e-mail: bmj10@cam.ac.uk). News on GNVQ science The Institute of Physics and the Royal Society of Chemistry are currently financing the compilation of a directory of resources to assist teachers in identifying and selecting suitable materials for teaching the new GNVQ science specifications. Work on the first part of the directory will soon be completed and it is hoped to publish the material in both print and electronic forms before the end of the summer term. This first part covers resources - all evaluated by practising GNVQ teachers - supporting the teaching of the compulsory units for Advanced GNVQ Science. A small team comprising a physics teacher, a chemistry teacher and a biology teacher, all involved with GNVQ programmes and led by Dr Ken Gadd, has carried out the work. They have established a network of teachers around the country to help with the evaluation of curriculum materials. The next part of the project will be to examine the feasibility of providing a similar listing for the optional units at this level. Future development, depending on the availability of funds, will extend the project to Intermediate level programmes in science, including the Part One, once its structure has been agreed at QCA. Further information about the Directory and the next phase of development will be available in the autumn. Activities Physics on Stage The future of science, technology and the ensuing wealth creation potential for Britain will depend on the quality of science education in schools today. Yet the numbers studying physics, which underpins science and engineering, are falling. This problem is currently evident throughout Europe. CERN, ESA and ESO (the European centres for high-energy physics, cosmology, space and astronomy) have just launched Physics on Stage, a Europe-wide programme which aims to draw attention to some of the best practices in physics teaching in schools and colleges. During this year, national programmes are being planned in 22 nations, leading on to a celebratory event at CERN during the European Week for Science and Technology (6-11 November). Here 400 delegates from the 22 participating nations will gather to present selected projects. The UK will have 40 delegates present, funded by the EC and we are seeking practising teachers to contribute their simple, transferable, practical ideas. These can be kitemarked and your school can use the Physics on Stage logo. We would like to hear from both primary and secondary schools in the UK. Teachers can apply to join the delegation by saying what they have to offer to the festival and how they would contribute to the dissemination of good practice afterwards. This would be an opportunity to discover what novel ideas and insights there are on the continent and then to share what you have learned with colleagues at home. It would also be an excellent opportunity to show off some of the good practice from UK classrooms. In return for the week's trip to Geneva (and cover) we ask that participants commit themselves to sharing what they have learned with UK teachers - through meetings, advanced skills teaching or perhaps even writing an article (for Physics Education?). Applications should be supported by a letter from your headteacher. Schools, other organizations and individuals may apply for a kite-mark for a project but the application should be supported by a letter from someone unconnected with the organization of the project. Nominations should be sent to Dr Steven Chapman, Secretary to the UK National Steering Committee Physics on Stage, 76 Portland Place, London W1N 3DH (e-mail: steven.chapman@iop.org), from whom further information about this initiative can also be obtained. More details can additionally be found on the website at www.physics-on-stage.co.uk. The closing date for kite-marking of projects is 30 September and that for applications to travel to Geneva is 30 July.

    Holton, Avery E; Chyi, Hsiang Iris

    2012-11-01

    News producers continue to increase their volume of production and delivery platforms in an effort to reach and maintain news consumers. However, consumers may not necessarily find more news desirable. Previous studies have suggested that information surplus can lead to negative outcomes for consumers, but research of outcomes related to news production and consumption has been scant. This study explores novel areas of news surplus and overload, empirically examining factors associated with the degree of perceived overload across a broad spectrum of news delivery platforms. The findings reveal that the majority of today's news consumers feel overloaded with the amount of news they are confronted with. Gender, news interest, and the use of specific news platforms and outlets predict the degree of that overload. News access through platforms and outlets such as computers, e-readers, and Facebook is positively associated with overload, whereas other platforms such as television and the iPhone are negatively associated with overload. Implications for media psychology and news consumption are discussed. PMID:23020743

    Scientists, observatories, academic institutions and funding agencies persistently review the usefulness and productivity of investment in scientific research. The Science News Metrics was created over 10 years ago to review NASA's performance in this arena. The metric has been useful for many years as one facet in measuring the scientific discovery productivity of NASA-funded missions. The metric is computed independently of the agency and has been compiled in a consistent manner. Examination of the metric yields year-by-year insight into NASA science successes in a world wide context. The metric has shown that NASA's contribution to worldwide top science news stories has been approximately 5% overall with the Hubble Space Telescope dominating the performance.

  6. Soft X-ray production by photon scattering in pulsating binary neutron star sources

    NASA Technical Reports Server (NTRS)

    Bussard, R. W.; Meszaros, P.; Alexander, S.

    1985-01-01

    A new mechanism is proposed as a source of soft (less than 1 keV) radiation in binary pulsating X-ray sources, in the form of photon scattering which leaves the electron in an excited Landau level. In a plasma with parameters typical of such sources, the low-energy X-ray emissivity of this mechanism far exceeds that of bremsstrahlung. This copious source of soft photons is quite adequate to provide the seed photons needed to explain the power-law hard X-ray spectrum by inverse Comptonization on the hot electrons at the base of the accretion column.

  7. Variability of antibiotic susceptibility and toxin production of Staphylococcus aureus strains isolated from skin, soft tissue, and bone related infections

    PubMed Central

    2013-01-01

    Background Staphylococcus aureus is an opportunistic commensal bacterium that mostly colonizes the skin and soft tissues. The pathogenicity of S. aureus is due to both its ability to resist antibiotics, and the production of toxins. Here, we characterize a group of genes responsible for toxin production and antibiotic resistance of S. aureus strains isolated from skin, soft tissue, and bone related infections. Results A total of 136 S. aureus strains were collected from five different types of infection: furuncles, pyomyositis, abscesses, Buruli ulcers, and osteomyelitis, from hospital admissions and out-patients in Benin. All strains were resistant to benzyl penicillin, while 25% were resistant to methicillin, and all showed sensitivity to vancomycin. Panton-Valentine leukocidin (PVL) was the most commonly produced virulence factor (70%), followed by staphylococcal enterotoxin B (44%). Exfoliative toxin B was produced by 1.3% of the strains, and was only found in isolates from Buruli ulcers. The tsst-1, sec, and seh genes were rarely detected (?1%). Conclusions This study provides new insight into the prevalence of toxin and antibiotic resistance genes in S. aureus strains responsible for skin, soft tissue, and bone infections. Our results showed that PVL was strongly associated with pyomyositis and osteomyelitis, and that there is a high prevalence of PVL-MRSA skin infections in Benin. PMID:23924370

    2013-05-01

    Wastewaters from the soft drinks industry were examined as media for producing bioethanol using yeast-mediated fermentation. Fermentation assays were performed using cola-type, orange and lemon-lime soft drinks and the biomass, sugar and ethanol levels were monitored over time. The effect of the addition of yeast extract was evaluated; the results indicated that 15 g/L is a suitable value for successful fermentation. Depletion of the sugars contained in the soft drinks (10-12% w/v) was achieved in less than 12 h when the medium was inoculated with 2 g/L of Saccharomyces cerevisiae var. Windsor. Ethanol yields were close to the theoretical values. The performance of several kinetic models was evaluated, and their parameters were determined. A model including inhibition by ethanol enabled the best adjustment of the experimental results in all assayed media. Some soft drinks include sodium benzoate in their formulae, the effect of which on yeast metabolism is discussed. PMID:23567674

    The results of experiments testing the effects of yeasts, sunlight, and temperature on the food dyes tartrazine, ponceau 4R, indigotin and azorubin (used for colouring ginger soft drink) are reported. Light was found to exert a greater influence than heat, and yeasts growth hastened colour degradation. Yeasts assimilated to varying extent the colouring compounds and, when failing to do it, showed a certain power of adsorption by the no longer viable cells. PMID:1509827

  10. In vitro screening of potential probiotic activities of selected lactobacilli isolated from unpasteurized milk products for incorporation into soft cheese.

    PubMed

    Coeuret, Valrie; Gueguen, Micheline; Vernoux, Jean Paul

    2004-11-01

    The aim was to select potentially probiotic lactobacilli from 88 strains isolated from unpasteurized milk and cheese products, and to incorporate these bacteria in a viable state into a soft cheese, without changing its quality. The survival of these bacteria was assessed in acidic and bile conditions, after freezing at -80 degrees C. Four strains from unpasteurized Camembert--two Lactobacillus plantarum strains and two Lb. paracasei/casei strains--were identified and typed by PCR and PFGE and were found to display potentially probiotic characteristics in addition to resistance to low pH and bile. These characteristics were resistance to lysozyme, adhesion to CACO-2 cells, antimicrobial effects against common foodborne pathogens (Listeria monocytogenes, Staphylococcus aureus, Salmonella spp., Escherichia coli, innocuity following the ingestion of high doses by mice and appropriate antibiotic susceptibility profiles. The potential of Lb. plantarum strain UCMA 3037 for incorporation into a soft cheese (Pont-l'Eveque registered designation of origin (RDO)) was investigated. This strain grew well and survived in sufficient numbers (more than 10(7) cfu/g throughout the shelf-life of the product) in the cheese. This strain did not change the quality score of the product until the best before date (75 days after manufacture). Thus, unpasteurized Camembert is a natural source of potentially probiotic lactobacilli, which could be used as an additive in the development of potentially probiotic soft cheeses. Further work is required to demonstrate the persistence and efficacy of these strains in the human host upon ingestion. PMID:15605712

  13. Localising News: Translation and the "Global-National" Dichotomy

    ERIC Educational Resources Information Center

    Orengo, Alberto

    2005-01-01

    Due to the peculiar nature of news texts, the adoption of a theory of "localisation" rather than conventional translation theories accounts more easily for both the commercial nature and the global scale of news distribution. News texts are global products which are distributed through a localisation process involving not only reception by locales

  14. Image Analysis via Soft Computing: Prototype Applications at NASA KSC and Product Commercialization

    NASA Technical Reports Server (NTRS)

    Dominguez, Jesus A.; Klinko, Steve

    2011-01-01

    This slide presentation reviews the use of "soft computing" which differs from "hard computing" in that it is more tolerant of imprecision, partial truth, uncertainty, and approximation and its use in image analysis. Soft computing provides flexible information processing to handle real life ambiguous situations and achieve tractability, robustness low solution cost, and a closer resemblance to human decision making. Several systems are or have been developed: Fuzzy Reasoning Edge Detection (FRED), Fuzzy Reasoning Adaptive Thresholding (FRAT), Image enhancement techniques, and visual/pattern recognition. These systems are compared with examples that show the effectiveness of each. NASA applications that are reviewed are: Real-Time (RT) Anomaly Detection, Real-Time (RT) Moving Debris Detection and the Columbia Investigation. The RT anomaly detection reviewed the case of a damaged cable for the emergency egress system. The use of these techniques is further illustrated in the Columbia investigation with the location and detection of Foam debris. There are several applications in commercial usage: image enhancement, human screening and privacy protection, visual inspection, 3D heart visualization, tumor detections and x ray image enhancement.

  15. Higgs boson production with one bottom quark including higher-order soft-gluon corrections

    Field, B.; Reina, L.; Jackson, C. B.

    2007-10-01

    A Higgs boson produced in association with one or more bottom quarks is of great theoretical and experimental interest to the high-energy community. A precise prediction of its total and differential cross section can have a great impact on the discovery of a Higgs boson with large bottom-quark Yukawa coupling, like the scalar (h{sup 0} and H{sup 0}) and pseudoscalar (A{sup 0}) Higgs bosons of the minimal supersymmetric standard model in the region of large tan{beta}. In this paper we apply the threshold resummation formalism to determine both differential and total cross sections for bg{yields}b{phi} (where {phi}=h{sup 0},H{sup 0}), including up to next-to-next-to-next-to-leading order soft plus virtual QCD corrections at next-to-leading logarithmic accuracy. We present results for both the Fermilab Tevatron and the CERN Large Hadron Collider.

  19. Drift tube soft-landing for the production and characterization of materials: Applied to Cu clusters

    SciTech Connect

    Davila, Stephen J.; Birdwell, David O.; Verbeck, Guido F.

    2010-03-15

    We have recently developed a soft-landing (SL) instrument that is capable of depositing ions onto substrates for preparative and developmental research of new materials using a laser ablation source. This instrument was designed with a custom drift tube and a split-ring ion optic for the isolation of selected ions. The drift tube allows for the separation and thermalization of ions formed after laser ablation through collisions with an inert bath gas. These collisions allow the ions to be landed at energies below 1 eV onto substrates. The split-ring ion optic is capable of directing ions toward the detector or a landing substrate for selected components. Experiments will be shown ablating Cu using an Nd:YAG (1064 and 532 nm) for cluster formation and landing onto a muscovite (mica) surface. The laser ablation of Cu in 8 Torr of He gas gives a spectrum that contains multiple peaks corresponding to Cu{sub n}, Cu{sub n}O{sub m} clusters, and their corresponding isomers. Atomic force microscopy and drift tube measurements were performed to characterize the performance characteristics of the instrument.

  1. Hard gains through soft contracts: productive engagement of private providers in tuberculosis control.

    PubMed Central

    Lnnroth, Knut; Uplekar, Mukund; Blanc, Lopold

    2006-01-01

    Over the past decade, there has been a rapid increase in the number of initiatives involving "for-profit" private health care providers in national tuberculosis (TB) control efforts. We reviewed 15 such initiatives with respect to contractual arrangements, quality of care and success achieved in TB control. In seven initiatives, the National TB Programme (NTP) interacted directly with for-profit providers; while in the remaining eight, the NTP collaborated with for-profit providers through intermediary not-for-profit nongovernmental organizations. All but one of the initiatives used relational "drugs-for-performance contracts" to engage for-profit providers, i.e. drugs were provided free of charge by the NTP emphasizing that providers dispense them free of charge to patients and follow national guidelines for diagnosis and treatment. We found that 90% (range 61-96%) of new smear-positive pulmonary TB cases were successfully treated across all initiatives and TB case detection rates increased between 10% and 36%. We conclude that for-profit providers can be effectively involved in TB control through informal, but well defined drugs-for-performance contracts. The contracting party should be able to reach a common understanding concerning goals and role division with for-profit providers and monitor them for content and quality. Relational drugs-for-performance contracts minimize the need for handling the legal and financial aspects of classical contracting. We opine that further analysis is required to assess if such "soft" contracts are sufficient to scale up private for-profit provider involvement in TB control and other priority health interventions.

    S ions with a mean charge state of about 14+ and Cl ions with a mean charge state of 12+ were used to study Ne L-shell vacancy production. The ions caused copious production of NeII-NeVIII excited states with approximately 10 to the minus 18 sq cm cross sections. The induced recoil velocities might have application to a significantly higher resolution spectroscopy than is possible with beam-foil methods.

Given about three weeks notice, we can outfit you with a variety of materials that will help others get tuned in to the good things that are happening in chemical education. We can send you an assortment of Journal issues, subscription forms, our Publications/Software Catalog, reprints from the Viewpoints series, copies of Classroom Activities, or JCE Gift Award Certificates, assuming that supplies are available. Of course we can arrange for the group to have temporary access to JCE Online. We can send you a brochure about the Ambassador program or answer any questions - just ask: email to jce@chem.wisc.edu; phone 1-800-991-5534 (U.S.) or 608-262-5153 (non-U.S.); fax 608-265-8094. If by chance you were a Journal Ambassador in 1999 but your name was not included, just let us know so that you can be recognized in a future column. Gift Subscription Awards As spring, the season of awards, approaches, we remind you of our handy Gift Certificates (a replica is shown on page 142). A gift of the Journal is not only affordable (gift subscriptions are 37/year (U.S.), 50/year (non-U.S.), but has lasting value. This is a really good way to help someone just starting out on a teaching career. An idea worth sharing comes from Carl Minnier of Essex Community College in Baltimore. He is chair of the Student Awards Committee of the Maryland Section of the ACS. This section has asked for 25 certificates because they honor annually an outstanding student from each of the two-year and four-year colleges within the territory of the Maryland Section. Want another interesting idea: give a one-year subscription to each Undergraduate Research Symposium participant. Classroom Activities for Outreach Many of our readers are involved with outreach programsindividually in their child's class, in a regional group that visits schools, in a van program, or as a demonstrator at their local science museum. Many readers have enthusiastically reported that our Classroom Activities series is a great resource for such programs. Since the Activities are designed for a high school classroom or lab (Activity 24 in this continuing series can be found in this issue), they are purposely not demanding of equipment, facilities, or time. But outreach activities often take place in very restricted environments, perhaps without sinks or electricity, sometimes with limited table space. So that we can provide timely advice in recommending activities for you to take "on the road", Nancy Gettys and Erica Jacobsen of the Journal staff have done an analysis of each, recommending whether it might be done in a workshop setting (where tables, a sink, and electricity could be expected) or in a booth (probably no sink and very limited space). There are also very useful notes. Some sample entries are: Activity:What's Gluep? Characterizing a Cross-Linked Polymer. J. Chem. Educ. 1998, 75, 1432A (November 1998).

Soaring Endowments: Research Corp. Report "The Midas Touch: Do Soaring Endowments Have Any Impact on College Science?" is the title of their 1998 annual report, just published by Research Corporation. In it the foundation reports that endowment growth appears to have only incidental effects on ongoing support for college research and education in the physical sciences. More likely targets for expenditures are new and remodeled buildings and student aid. Interviews with college administrators support the conclusion that large endowments do not guarantee the funds needed to hire enough faculty scientists to teach and do related research with students, to house the sciences in up-to-date buildings, or equip laboratories with modern instrumentation. Copies of "The Midas Touch" are available without charge from Research Corporation, 101 North Wilmot Road, Suite 250, Tucson, AZ 85711.

  4. CGC/saturation approach for soft interactions at high energy: Inclusive production

    NASA Astrophysics Data System (ADS)

    Gotsman, E.; Levin, E.; Maor, U.

    2015-06-01

    In this letter we demonstrate that our dipole model is successful in describing inclusive production within the same framework as diffractive physics. We believe that this achievement stems from the fact that our approach incorporates the positive features of the Reggeon approach and CGC/saturation effective theory, for high energy QCD.

    News from Journal House

    Guidelines for Submission The Journal's current Guide to Submissions can be found on pages 29-30 of this issue. They have been streamlined a bit and also include a handy check list. This information is also available on JCE Online at http://jchemed.chem.wisc.edu/Journal/Authors/. Wanted: Demo Checkers The Tested Demonstrations column needs people who like to try out demos. Column editor Ed Vitz is looking for additional volunteers to serve as "checkers" for manuscripts that have been submitted to the Journal for possible publication as Tested Demonstrations. A checker is expected to perform two functions: to review the manuscript for accuracy and novelty, and to attempt to perform the demonstration according to the procedure supplied by the author. Checkers may suggest important improvements in demonstration procedures, and for their efforts they are cited in the byline when the manuscript is published. For instance, the demo showing the yellow cascading precipitates (lead iodide) made from potassium iodide and lead nitrate was submitted by Wobbe de Vos and checked by Kim Kostka. The (yellow) cascading precipitates are from "Using Large Glass Cylinders To Demonstrate Chemical Reactions" that appeared in the April 1999 issue of JCE. We prefer that checkers begin the review process (which may in some cases involve procuring supplies) very soon after being contacted so that their review can be completed in the timely manner that authors deserve. Checkers are usually teachers who routinely present lecture demonstrations in their classes in either high school or colleges. We try not to call on checkers more often than once a year, which is one of the reasons for this request. Another is that we lose many highly valued, experienced checkers to retirement or other endeavors. Prospective checkers may want to look at a copy of the JCE Tested Demonstration Evaluation Form. It can be found on the Web at http://www.kutztown.edu/ vitz/TD/TDhome.html. This site also has links to JCE guidelines for prospective authors. Volunteers should contact Vitz by the medium of their preference: Ed Vitz, Editor, Tested Demonstrations, Journal of Chemical Education, Department of Chemistry, Kutztown University, Kutztown, PA 19530; phone: 610/683-4443; fax: 610/683-1352; email: vitz@kutztown.edu.

  6. Analysis of sugar degradation products with ?-dicarbonyl structure in carbonated soft drinks by UHPLC-DAD-MS/MS.

    PubMed

    Gensberger, Sabrina; Glomb, Marcus A; Pischetsrieder, Monika

    2013-10-30

    Sugar-sweetened carbonated soft drinks (CSDs) are broadly consumed worldwide. The added sugar, particularly high-fructose corn syrup (HFCS), can be an important source of sugar degradation products, such as ?-dicarbonyl compounds. This study recorded the ?-dicarbonyl profile in CSDs by ultrahigh-performance liquid chromatography with hyphenated diode array-tandem mass spectrometry after derivatization with o-phenylenediamine. Thus, 3-deoxy-D-erythro-hexos-2-ulose (3-DG), D-lyxo-hexos-2-ulose (glucosone), 3-deoxy-D-threo-hexos-2-ulose (3-DGal), 1-deoxy-D-erythro-hexos-2,3-diulose (1-DG), 3,4-dideoxyglucosone-3-ene (3,4-DGE), methylglyoxal, and glyoxal were identified as major ?-dicarbonyls and, with the exception of glyoxal, quantified (recovery rates, 85.6-103.1%; RSD, 0.8-3.6%). Total ?-dicarbonyl concentration in 25 tested commercial products ranged between 0.3 and 116 ?g/mL and was significantly higher in HFCS-sweetened CSDs compared to CSDs sweetened with HFCS and sucrose or with sucrose alone. Predominant was 3-DG (?87 ?g/mL) followed by glucosone (?21 ?g/mL), 3-DGal (?7.7 ?g/mL), 1-DG (?2.8 ?g/mL), methylglyoxal (?0.62 ?g/mL), and 3,4-DGE (?0.45 ?g/mL). PMID:23452313

    Summary Background Phenol-soluble modulins (PSMs) are amphipathic, pro-inflammatory proteins secreted by most Staphylococcus aureus isolates. This study tested the hypothesis that in vitro PSM production levels are associated with specific clinical phenotypes. Methods 177 methicillin-resistant S. aureus (MRSA) isolates from infective endocarditis (IE), skin and soft tissue infection (SSTI), and hospital-acquired/ventilator-associated pneumonia (HAP) were matched by geographic origin, then genotyped using spa-typing. In vitro PSM production was measured by high performance liquid chromatography/mass spectrometry. Statistical analysis was performed using Chi-squared or Kruskal–Wallis tests as appropriate. Results Spa type 1 was significantly more common in SSTI isolates (62.7% SSTI; 1.7% IE; 16.9% HAP; p < 0.0001) while HAP and IE isolates were more commonly spa type 2 (0% SSTI; 37.3% IE; 40.7% HAP; p < 0.0001). USA300 isolates produced the highest levels of PSMs in vitro. SSTI isolates produced significantly higher quantities of PSMα1-4, PSMβ1, and δ-toxin than other isolates (p < 0.001). These findings persisted when USA300 isolates were excluded from analysis. PMID:26079275

  8. Two-loop soft anomalous dimensions for single top quark associated production with a W{sup -} or H{sup -}

    SciTech Connect

    Kidonakis, Nikolaos

    2010-09-01

    I present results for the two-loop soft anomalous dimensions for associated production of a single top quark with a W boson or a charged Higgs boson. The calculation uses expressions for the massive cusp anomalous dimension, which are presented in different forms, and it allows soft-gluon resummation at next-to-next-to-leading-logarithm (NNLL) accuracy. From the NNLL resummed cross section I derive approximate NNLO cross sections for bg{yields}tW{sup -} and bg{yields}tH{sup -} at LHC energies of 7, 10, and 14 TeV.

  9. Sorption and recycling of harmful materials during the production of polyurethane (PUR) block soft foam. Compendium on low- and non-waste technology. Monograph

    SciTech Connect

    1984-04-19

    The technology involves the sorption and recycling of harmful materials in process gases generated during the production of polyurethane (PUR) block soft foam. Activated charcoal is used for removing CC13F and TDI which are emitted with exhaust air during the conventional production process. Adsorption of TDI is an irreversible process, which eliminates the option of recovering the TDI. The CC13F, however, is recovered through regeneration of the charcoal bed with hot steam.

  10. Soft X-ray irradiation of methanol ice: Formation of products as a function of photon energy

    SciTech Connect

    Chen, Y.-J.; Juang, K.-J.; Yih, T.-S.; Ciaravella, A.; Cecchi-Pestellini, C.; Muñoz Caro, G. M.; Jiménez-Escobar, A.

    2013-12-01

    Pure methanol ices have been irradiated with monochromatic soft X-rays of 300 and 550 eV close to the 1s resonance edges of C and O, respectively, and with a broadband spectrum (250-1200 eV). The infrared (IR) spectra of the irradiated ices show several new products of astrophysical interest such as CH{sub 2}OH, H{sub 2}CO, CH{sub 4}, HCOOH, HCOCH{sub 2}OH, CH{sub 3}COOH, CH{sub 3}OCH{sub 3}, HCOOCH{sub 3}, and (CH{sub 2}OH){sub 2}, as well as HCO, CO, and CO{sub 2}. The effect of X-rays is the result of the combined interactions of photons and electrons with the ice. A significant contribution to the formation and growth of new species in the CH{sub 3}OH ice irradiated with X-rays is given by secondary electrons, whose energy distribution depends on the energy of X-ray photons. Within a single experiment, the abundances of the new products increase with the absorbed energy. Monochromatic experiments show that product abundances also increase with the photon energy. However, the abundances per unit energy of newly formed species show a marked decrease in the broadband experiment as compared to irradiations with monochromatic photons, suggesting a possible regulatory role of the energy deposition rate. The number of new molecules produced per absorbed eV in the X-ray experiments has been compared to those obtained with electron and ultraviolet (UV) irradiation experiments.

    News from Journal House Perspective on JCE Online Recently a reader asked us for a perspective on JCE Onlinehow the chemical education community is receiving it and how the Journal staff itself views it. We share our responses below. Subscriber Numbers How many people subscribe to JCE Online+? As of June 1, 1999, our records show that 13% of individual JCE subscriptions in the USA include JCE Online+. This percentage has increased significantly during the past year- in June 1998 it was approximately 4% and December 1998 about 7%. Almost all subscribers to JCE Online subscribe to print as well. Since JCE Online has only very recently been made available to institutional subscribers, there are no numbers to report. There has been considerable interest in online from libraries. Given that JCE Online+ is a fairly recent subscriber option and that many subscribers have a wait-and-see approach to any new option, we feel that the numbers above are quite high. The steady growth is encouraging. Online Usage How many people visit our Web site? Statistics for the period January 1, 1999, through May 31, 1999, that may be of interest include:

    Total Pages Served 361,115

    Total Visits 138,377

    Total Unique Visitors 51,744

    Total Repeat Visitors 11,536

    Average Visit Length 03:05

    Average Requests/Visit 10.8

    Average Pages/Visit 2.6

    Average Daily Visits 916 Online Rationale and Expectations JCE Online is a very important part of the whole Journal, but we do not expect it to supplant print: online and print are very different media. Usage of JCE Online is growing steadily; our subscribers are realizing what we have learned: it is not possible to deliver the Journal in the print medium alone- print is no longer adequate to accomplish our mission. Examples of things not possible in print include:

    ·JCE Index to all 76 years of Journal issues, available all the time with responses within seconds.

    ·Supplementary materials that are important to only a limited number of our subscribers; materials that augment laboratory experiments are a good example.

    ·Supplementary videos, such as the videos, still images, and excerpts from interviews with nuclear chemists that give fuller meaning to the Viewpoints article "Chemistry of the Heaviest Elements- One Atom at a Time" referred to below.

    ·Internet feature columns are more effective in a dynamic medium. Two that are in place are Mathcad in the Chemistry Curriculum (edited by Theresa Zielinski) and Conceptual Questions and Challenge Problems (edited by William Robinson and Susan Nurrenbern).

    ·Buyers Guides have their content updated often and link to other useful sites. There is one for books and software and another for supplies and equipment. Elements Added to Periodic Table Two new transuranic elements have been added to the list in the Viewpoints article "Chemistry of the Heaviest ElementsOne Atom at a Time" by Darleane C. Hoffman and Diana M. Lee (JCE, 1999, 76, 331). The new elements have atomic numbers 118 and 116. The path to the discovery of these elements was predicted by Robert Smolanczuk, a young Polish theorist whose calculations led him to conclude that a lead-krypton collision technique could produce element 118, which then decays to element 116. Others questioned his results, but Hoffman invited him to join the team at the Lawrence Berkeley National Laboratory and a decision was made to try out his ideas. The result was almost complete verification of Smolanczuk's calculations. The experimental team was headed by Kenneth E. Gregorich; Darleane Hoffman is one of 15 codiscoverers of element 118. Awards Willard Gibbs Medal Lawrence F. Dahl of the University of Wisconsin-Madison is the recipient of 1999 Willard Gibbs Medal, the highest award of the Chicago Section of the American Chemical Society. It is awarded annually to a world-renowned scientist selected by a jury of panelists composed of eminent chemists elected by the Board of Directors of the Chicago Section. The award was presented at the Chicago Section's meeting in May 1999. Courses, Seminars, Meetings, Opportunities Grant Program for Senior Scientist Mentors The Camille and Henry Dreyfus Foundation announces a new initiative within its Special Grant Program in the Chemical Sciences: the Senior Scientist Mentors. Undergraduate participation in research is generally acknowledged to be one of the most effective ways for students to learn and appreciate chemistry. Key to a meaningful research experience is the advising and counseling a student can receive from leaders in chemical research. Application Details Emeritus faculty who maintain active research programs in the chemical sciences may apply for one of a limited number of awards that will allow undergraduates to do research under their guidance. Successful applicants, who are expected to be closely engaged in a mentoring relationship with the students, will receive grants of 10,000 annually for two years (20,000 total) for undergraduate stipends and modest research support. In approximately three pages, applicants should describe their ongoing research and the nature of the participation by undergraduates in the research activity. The role of the applicant as mentor should be clearly outlined. The application should also contain a curriculum vitae of no more than five pages that includes representative publications; a letter of support from the department chair that also commits appropriate space and facilities for the undergraduate participants; and a letter of support from a colleague (preferably from outside the department) who is familiar with the applicant's research and teaching. This initiative is open to all institutions that offer bachelor's or higher degrees in the chemical sciences. Use the standard cover page for the Special Grant Program in the Chemical Sciences, which is available at www.dreyfus.org. "Senior Scientist Mentors" should be entered as the project title. An original and five copies of the application are required. Applications should be received in the Foundation office (555 Madison Avenue, Suite 1305, New York, NY 10022) by September 1, 1999; awards will be announced toward the end of January 2000.

    Many students enroll in video production courses in high school as part of a vocational, career, or technical program. While there has been an explosion of scholarly work in digital literacy in informal settings, less is known about how digital and media literacy competencies are developed through school-based video production courses.

  13. Size Structure of Marine Soft-Bottom Macrobenthic Communities across Natural Habitat Gradients: Implications for Productivity and Ecosystem Function

    PubMed Central

    Macdonald, Tara A.; Burd, Brenda J.; van Roodselaar, Albert

    2012-01-01

    Size distributions of biotic assemblages are important modifiers of productivity and function in marine sediments. We investigated the distribution of proportional organic biomass among logarithmic size classes (2?6J to 216J) in the soft-bottom macrofaunal communities of the Strait of Georgia, Salish Sea on the west coast of Canada. The study examines how size structure is influenced by 3 fundamental habitat descriptors: depth, sediment percent fines, and organic flux (modified by quality). These habitat variables are uncorrelated in this hydrographically diverse area, thus we examine their effects in combination and separately. Cluster analyses and cumulative biomass size spectra reveal clear and significant responses to each separate habitat variable. When combined, habitat factors result in three distinct assemblages: (1) communities with a high proportion of biomass in small organisms, typical of shallow areas (<10 m) with coarse sediments (<10% fines) and low accumulation of organic material (<3.0 gC/m2/yr/?15N); (2) communities with high proportion of biomass in the largest organisms found in the Strait, typical of deep, fine sediments with high modified organic flux (>3 g C/m2/yr/?15N) from the Fraser River; and (3) communities with biomass dominated by moderately large organisms, but lacking the smallest and largest size classes, typical of deep, fine sediments experiencing low modified organic flux (<3.0 gC/m2/yr/?15N). The remaining assemblages had intermediate habitat types and size structures. Sediment percent fines and flux appear to elicit threshold responses in size structure, whereas depth has the most linear influence on community size structure. The ecological implications of size structure in the Strait of Georgia relative to environmental conditions, secondary production and sediment bioturbation are discussed. PMID:22911694

    Unification of Journal Options Beginning in 2000, the Journal subscription form will get much simpler and your Journal subscription will bring you even more than previously. Below is an outline of how the new system will work for individuals. Subscriptions for Individuals

    • Beginning September 1, 1999, all Journal print subscriptionscurrent, continuing, new, and renewalwill bring you monthly print issues and give you full access to JCE Online+everything that we have online.
    • If you don't want paper copy of your issue, there is a No-Print Optionwe donate your print copy to our Teacher Workshop Program and you have full access to everything online.
    • If you do want both paper and online but don't want to keep back issuessaving storage spaceyou can purchase JCE CD each year.
    A chart illustrating this new system appears below. It lists all subscription choices for individuals in the U. S., for ACS Student Affiliates, and for non-U.S. individuals. Other Subscription Rates There are now two types of subscriptions for libraries. These are described under New IP-Address Option for Libraries, below. For information about Promotional (larger quantities for workshops, classes, etc.) or Gift Subscription Award Certificate rates, contact the Journal (jce@chem.wisc.edu); 1-800-991-5534 (U.S.) or 608/262-5153. Extensions for Current JCE Online Subscribers At present there are more than 1,000 subscribers to JCE Online+: we think of these as our technological pioneers. These subscribers will have their subscriptions automatically extended according to the scheme below.

Password: 99990 New IP-Address Option for Libraries While standard username/password access (where all users share the same access information) may be fine for some libraries, others find this system too limited and therefore unworkable. Such institutions have requested access by IP address, with no prompting for UserName and Password. We believe that this is just the tip of the iceberg and that many, if not most, library and institutional subscribers will want this type of access in the near future. Therefore we have added an IP-Address subscription option for libraries and institutions. With this option, the library or institution provides us with a list of all IP numbers that will receive access. Any desktop computer using one of these IP numbers will have immediate access, without the prompt for name and password. Because this requires considerably more administrative work on our end, there is a somewhat larger (but reasonable) fee. Please make your librarian aware of this new option that will provide you and all your colleagues with desktop access to JCE. Immediate Access to Online At present new subscribers are not able to get immediate access to JCE Onlinea limitation for subscribers who order over the telephone using a credit card. We now have an arrangement with our subscription fulfillment agent to give new subscribers immediate access to JCE Online by a guest account. The temporary guest account information will be provided as a part of the telephone order; when the new account is active, the account information will be emailed. Remember to Provide Your Email Address Knowing your email address has become important for Journal communication. In addition to account information, we will send an order confirmation to each subscriber who provides an email address. For those who want it, we intend, in the near future, to send an email message announcing when each month's issue goes online. We do not sell or give email addresses to anyone else. Keeping Up to Date with JCE Online JCE Online will continue to change and expand, as the technology around us changes and as new features and columns are added. The best way to keep abreast of new developments is to look for the JCE Online column in both print and online. Jon Holmes, editor of JCE Online, uses this column to keep readers in touch with the latest happenings:
    • JCE Online FAQs (March 1999, p 446)
    • JCE Online 99 (April 1999, p 584)
    • JCE Feature Columns (May 1999, p 718)

    JCE: A Good Deal That Keeps Getting Better If you carry copies of JCE around in hopes of finding time to read them, you may think they are getting heavierand they are. Your Journal was more than a third bigger in 1998 than it was in 1995! We have printed more pages every year since 1996 (see graph for the past 25 years). We estimate that you will receive more than 2000 pages this year and even more next year. This is more pages than at any time in the Journal 's history, excepting the four years 1929-1932, when the pages were smaller. We are printing more pages because we need to. We have many good manuscripts that have been peer reviewed and accepted and now are awaiting publication in print. The time between acceptance of a manuscript and its publication is already too long. Unless we print more pages, it will grow longer. For the past three years we have been slowly but steadily reducing this publication lag, and we don't want to stop now. JCE accepts only those manuscripts that pass strict peer review (fewer than half the number we receive), but we are receiving more manuscripts each year, with no apparent decline in quality. A recent analysis of our expenses revealed that to process a subscription order, print 12 issues of JCE, and mail those 12 issues to you costs about 37 - exactly what we charged in 1999 for an individual subscription. This 37 does not include the cost of the editorial work that goes into making JCE an excellent journal: evaluating, reviewing, and working with authors to improve manuscripts, copy editing and preparing proofs, and laying out and desktop publishing each of the 600 articles we publish each year. JCE is a nonprofit operation, but we cannot survive if we provide a product whose production costs exceed income. Therefore the Board of Publication found it necessary to increase the individual subscription fee for next year to 42. This is a 31% increase over 1995 (less than 21% if inflation is taken into account), which is significantly below the estimated 40% increase in number of pages you will receive in 2000. Another way to see the tremendous value of JCE is to compare the cost per page for various journals. JCE costs less per printed page than any other journal we know. A quick survey revealed that cost per page ranges from 2 cents for JCE to 2-28 cents for various ACS journals to 46 cents for a science education research journal published by a commercial publisher to as much as 2 for a commercially published science research journal. JCE 's costs to institutional subscribers such as libraries are even more favorable by comparison with other journals, because we want JCE to be accessible to libraries in high schools and small colleges. How can we afford to be such a bargain? The entire community of chemical education contributes to writing, reviewing, and testing the materials we publish. Some members volunteer even more time as feature editors. The editorial staff work hard and often spend more than the typical work week doing their jobs superlatively and making this a great Journal. The Board of Publication, the Division of Chemical Education, and everyone associated with the Journal are dedicated to providing our readers with the best possible publication at the lowest possible cost. All that effort counts for a lot, and you are the beneficiary. What can you do to help continue this tradition of excellence at minimal cost? Become a JCE Ambassador. Ask others to join with us as subscribers. Or give them gift subscriptions (an even better bargain) and encourage them to continue to subscribe. The more subscribers we have, the less the cost to each. Also, volunteer your time as an author, reviewer, column editor, or in some other capacity. JCE is a great journal because its readers have given of themselves to make it that way. Please continue to work with us to keep it that way.

  20. Soft lubrication

    NASA Astrophysics Data System (ADS)

    Skotheim, Jan; Mahadevan, Laksminarayanan

    2004-11-01

    We study the lubrication of fluid-immersed soft interfaces and show that elastic deformation couples tangential and normal forces and thus generates lift. We consider materials that deform easily, due to either geometry (e.g a shell) or constitutive properties (e.g. a gel or a rubber), so that the effects of pressure and temperature on the fluid properties may be neglected. Four different system geometries are considered: a rigid cylinder moving tangentially to a soft layer coating a rigid substrate; a soft cylinder moving tangentially to a rigid substrate; a cylindrical shell moving tangentially to a rigid substrate; and finally a journal bearing coated with a thin soft layer, which being a conforming contact allows us to gauge the influence of contact geometry. In addition, for the particular case of a soft layer coating a rigid substrate we consider both elastic and poroelastic material responses. Finally, we consider the role of contact geometry in the context of the journal bearing, a conforming contact. For all these cases we find the same generic behavior: there is an optimal combination of geometric and material parameters that maximizes the dimensionless normal force as a function of the softness.

  4. Optimum thickness of soft magnetic phase in FePt/FeCo permanent magnet superlattices with high energy product and large magnetic anisotropy energy

    NASA Astrophysics Data System (ADS)

    Jain, Sandeep Kumar; Chittari, Bheema Lingam; Kumar, Vijay

    2016-02-01

    Ab initio calculations on hard/soft (FePt)m/(FeCo)n, (m = 4, 6, 8 and n = 2-2m) magnetic superlattices show that the B2 type FeCo layers become anisotropic with varying interlayer spacing and enhanced magnetic moments. The average magnetic moment in superlattices is higher than in bulk FePt, resulting in high maximum energy product for (FePt)4/(FeCo)8 which is nearly double the calculated value for bulk FePt. The calculation of the magnetic anisotropy energy shows that the optimal thickness of the soft magnetic phase for good permanent magnet behaviour of the superlattice is less than ˜2 nm.

  5. A false report of product tampering involving a rodent and soft drink can: light microscopy, image analysis and scanning electron microscopy/energy dispersive X-ray analysis.

    PubMed

    Platek, F; Ranieri, N; Wolnik, K A

    1997-11-01

    The "Pepsi Tamperings" of 1993 resulted in a large number of cases involving foreign objects reportedly found inside canned soft drinks. Although the majority of cases involved medical syringes and metallic objects, one case involved the report of a mouse found inside a can of Caffeine-Free Diet Pepsi. Using light and polarized light microscopy and computer-assisted image analysis, trace evidence and tooth structure from the suspect mouse were matched to scratches and indentions on the suspect can. Scanning electron microscopy and energy dispersive X-ray analysis were used to compare and match particles of gnawed metal from the lid of the suspect can to other particles recovered from the muzzle and stomach of the suspect mouse. The forensic analyses in this case proved the mouse could not have been canned in the soft drink product and refuted the defendant's sworn statements. PMID:9397564

  11. Soft electronics for soft robotics

    NASA Astrophysics Data System (ADS)

    Kramer, Rebecca K.

    2015-05-01

    As advanced as modern machines are, the building blocks have changed little since the industrial revolution, leading to rigid, bulky, and complex devices. Future machines will include electromechanical systems that are soft and elastically deformable, lending them to applications such as soft robotics, wearable/implantable devices, sensory skins, and energy storage and transport systems. One key step toward the realization of soft systems is the development of stretchable electronics that remain functional even when subject to high strains. Liquid-metal traces embedded in elastic polymers present a unique opportunity to retain the function of rigid metal conductors while leveraging the deformable properties of liquid-elastomer composites. However, in order to achieve the potential benefits of liquid-metal, scalable processing and manufacturing methods must be identified.

  13. Do you want the good news or the bad news first? The nature and consequences of news order preferences.

    PubMed

    Legg, Angela M; Sweeny, Kate

    2014-03-01

    Information often comes as a mix of good and bad news, prompting the question, "Do you want the good news or the bad news first?" In such cases, news-givers and news-recipients differ in their concerns and considerations, thus creating an obstacle to ideal communication. In three studies, we examined order preferences of news-givers and news-recipients and the consequences of these preferences. Study 1 confirmed that news-givers and news-recipients differ in their news order preferences. Study 2 tested two solutions to close the preference gap between news-givers and recipients and found that both perspective-taking and priming emotion-protection goals shift news-givers' delivery patterns to the preferred order of news-recipients. Study 3 provided evidence that news order has consequences for recipients, such that opening with bad news (as recipients prefer) reduces worry, but this emotional benefit undermines motivation to change behavior.

    From April 16, 2006, through May 30, 2013, a team of reviewers from HealthNewsReview.org, many of whom were physicians, evaluated the reporting by US news organizations on new medical treatments, tests, products, and procedures. After reviewing 1889 stories (approximately 43% newspaper articles, 30% wire or news services stories, 15% online pieces [including those by broadcast and magazine companies], and 12% network television stories), the reviewers graded most stories unsatisfactory on 5 of 10 review criteria: costs, benefits, harms, quality of the evidence, and comparison of the new approach with alternatives. Drugs, medical devices, and other interventions were usually portrayed positively; potential harms were minimized, and costs were ignored. Our findings can help journalists improve their news stories and help physicians and the public better understand the strengths and weaknesses of news media coverage of medical and health topics.

    We present a measurement of the top quark pair production cross section in p{bar p} collisions at {radical}s = 1.96 TeV using a data sample corresponding to 1.7 fb{sup -1} of integrated luminosity collected with the Collider Detector at Fermilab. We reconstruct t{bar t} events in the lepton+jets channel, consisting of e{nu}+jets and {mu}{nu}+jets final states. The dominant background is the production of W bosons in association with multiple jets. To suppress this background, we identify electrons from the semileptonic decay of heavy-flavor jets ('soft electron tags'). From a sample of 2196 candidate events, we obtain 120 tagged events with a background expectation of 51 {+-} 3 events, corresponding to a cross section of {sigma}{sub t{bar t}} = 7.8 {+-} 2.4 (stat) {+-} 1.6 (syst) {+-} 0.5 (lumi) pb. We assume a top-quark mass of 175 GeV/c{sup 2}. This is the first measurement of the t{bar t} cross section with soft electron tags in Run II of the Tevatron.

  6. Enzyme production by wood-rot and soft-rot fungi cultivated on corn fiber followed by simultaneous saccharification and fermentation.

    PubMed

    2009-05-27

    This research aims at developing a biorefinery platform to convert lignocellulosic corn fiber into fermentable sugars at a moderate temperature (37 °C) with minimal use of chemicals. White-rot (Phanerochaete chrysosporium), brown-rot (Gloeophyllum trabeum), and soft-rot (Trichoderma reesei) fungi were used for in situ enzyme production to hydrolyze cellulosic and hemicellulosic components of corn fiber into fermentable sugars. Solid-substrate fermentation of corn fiber by either white- or brown-rot fungi followed by simultaneous saccharification and fermentation (SSF) with coculture of Saccharomyces cerevisiae has shown a possibility of enhancing wood rot saccharification of corn fiber for ethanol fermentation. The laboratory-scale fungal saccharification and fermentation process incorporated in situ cellulolytic enzyme induction, which enhanced overall enzymatic hydrolysis of hemi/cellulose components of corn fiber into simple sugars (mono-, di-, and trisaccharides). The yeast fermentation of the hydrolyzate yielded 7.8, 8.6, and 4.9 g ethanol per 100 g corn fiber when saccharified with the white-, brown-, and soft-rot fungi, respectively. The highest ethanol yield (8.6 g ethanol per 100 g initial corn fiber) is equivalent to 35% of the theoretical ethanol yield from starch and cellulose in corn fiber. This research has significant commercial potential to increase net ethanol production per bushel of corn through the utilization of corn fiber. There is also a great research opportunity to evaluate the remaining biomass residue (enriched with fungal protein) as animal feed. PMID:21314197

  17. Ultra-sensitive detection of tumorigenic cellular impurities in human cell-processed therapeutic products by digital analysis of soft agar colony formation

    Contamination with tumorigenic cellular impurities is one of the most pressing concerns for human cell-processed therapeutic products (hCTPs). The soft agar colony formation (SACF) assay, which is a well-known in vitro assay for the detection of malignant transformed cells, is applicable for the quality assessment of hCTPs. Here we established an image-based screening system for the SACF assay using a high-content cell analyzer termed the digital SACF assay. Dual fluorescence staining of formed colonies and the dissolution of soft agar led to accurate detection of transformed cells with the imaging cytometer. Partitioning a cell sample into multiple wells of culture plates enabled digital readout of the presence of colonies and elevated the sensitivity for their detection. In practice, the digital SACF assay detected impurity levels as low as 0.00001% of the hCTPs, i.e. only one HeLa cell contained in 10,000,000 human mesenchymal stem cells, within 30 days. The digital SACF assay saves time, is more sensitive than in vivo tumorigenicity tests, and would be useful for the quality control of hCTPs in the manufacturing process. PMID:26644244

    An efficient protocol for the Agrobacterium tumefaciens-mediated transformation of calla lily (Zantedeschia elliottiana (W. Wats.) Engl. cultivar 'Florex Gold') is described. Shoot basal discs were co-cultivated with A. tumefaciens C58C1 carrying a plasmid containing neomycin phosphotransferase (nptII) and plant ferredoxin-like protein (pflp) genes. After Agrobacterium co-cultivation, the shoot basal discs were exposed to 100 mg l(-1) kanamycin for selection. Twenty-eight out of 260 discs (10.8%) were found to have survived and produced shoot clusters. Twenty-six of these were confirmed to contain the pflp transgene by PCR, ending up in 10% transformation efficiency. The disease resistance investigation revealed that 18 transgenic plants exhibited resistance to soft rot disease caused by Erwinia carotovora subsp. carotovora. The presence of pflp gene was demonstrated by PCR, and its accumulation and activity was confirmed by Western blot and disease resistance assay. This was the first report to show the successful transformation and resistance to a bacterial pathogen in Zantedeschia. The protocol is useful for the quality improvement of calla lily through genetic transformation. PMID:17033825

  1. Soft X-Ray Photoionizing Organic Matter from Comet Wild 2: Evidence for the Production of Organic Matter by Impact Processes

    2011-01-01

    The Stardust mission collected both mineral and organic matter from Comet Wild 2 [1,2,3,4]. The organic matter discovered in Comet Wild 2 ranges from aromatic hydrocarbons to simple aliphatic chains and is as diverse and complex as organic matter found in carbonaceous chondrites and interplanetary dust particles.[3,5,6,7,8,9]. Compared to insoluble organic matter from carbonaceous chondrites the organic matter in Comet Wild 2 more closely resembles organic matter found in the IDPS both hydrous and anhydrous. Common processes for the formation of organic matter in space include: Fischer-Tropsch, included with this aqueous large body and moderate heating alterations; UV irradiation of ices; and; plasma formation and collisions. The Fischer-Tropsch could only occur on large bodies processes, and the production of organic matter by UV radiation is limited by the penetration depth of UV photons, on the order of a few microns or less for most organic matter, so once organic matter coats the ices it is formed from, the organic production process would stop. Also, the organic matter formed by UV irradiation would, by the nature of the process, be in-sensitive to photodissocation from UV light. The energy of soft X-rays, 280-300 eV occur within the range of extreme ultraviolet photons. During the preliminary examination period we found a particle that nearly completely photoionized when exposed to photons in the energy range 280-310eV. This particle experienced a long exposure time to the soft x-ray beam which caused almost complete mass loss so little chemical information was obtain. During the analysis of our second allocation we have discovered another particle that photoionized at these energies but the exposure time was limited and more chemical information was obtained.

    Breaking bad news is one of the most stressful duties of the physician in oncology. Among other issues, it includes discussion of cancer diagnosis or the failure of therapy. The oncologist is often puzzled by an apprehension regarding the delivery of bad news. The fear to be exposed to unexpected strong emotional reactions by the patient, such as aggression or despair, may cause the oncologist to adopt unproductive coping strategies such as discussion about technical details while avoiding to deliver the main message. However, good communication skills are the key for a satisfying conversation with the patient. The oncologists' discomfort induced by the above mentioned apprehension is one of the most important barriers for a successful conversation. PMID:15991627

Dirac's college, St. John's of Cambridge, generously endowed annual lectures to be held at Cambridge University in his memory. This volume contains a much expanded version of the 1994 Dirac Lecture by Nobel Laureate Pierre Gilles de Gennes. The book presents an impressionistic tour of the physics of soft interfaces. Full of insight and interesting asides, it not only provides an accessible introduction to this topic, but also lays down many markers and signposts that will be of interest to researchers in physics or chemistry. Features discussions of wetting and dewetting, the dynamics of different types of interface and adhesion and polymer/polymer welding.

  6. Contact: Releasing the news

    NASA Astrophysics Data System (ADS)

    Pinotti, Roberto

    The problem of mass behavior after man's future contacts with other intelligences in the universe is not only a challenge for social scientists and political leaders all over the world, but also a cultural time bomb as well. In fact, since the impact of CETI (Contact with Extraterrestrial Intelligence) on human civilization, with its different cultures, might cause a serious socio-anthropological shock, a common and predetermined worldwide strategy is necessary in releasing the news after the contact, in order to keep possible manifestations of fear, panic and hysteria under control. An analysis of past studies in this field and of parallel historical situations as analogs suggests a definite "authority crisis" in the public as a direct consequence of an unexpected release of the news, involving a devastating "chain reaction" process (from both the psychological and sociological viewpoints) of anomie and maybe the collapse of today's society. The only way to prevent all this is to prepare the world's public opinion concerning contact before releasing the news, and to develop a long-term strategy through the combined efforts of scientists, political leaders, intelligence agencies and the mass media, in order to create the cultural conditions in which a confrontation with ETI won't affect mankind in a traumatic way. Definite roles and tasks in this multi-level model are suggested.

  6. Modeling Soft Matter

    NASA Astrophysics Data System (ADS)

    Kremer, Kurt

    Soft matter science or soft materials science is a relatively new term for the science of a huge class of rather different materials such as colloids, polymers (of synthetic or biological origin), membranes, complex molecular assemblies, complex fluids, etc. and combinations thereof. While many of these systems are contained in or are even the essential part of everyday products ("simple" plastics such as yoghurt cups, plastic bags, CDs, many car parts; gels and networks such as rubber, many low fat foods, "gummi" bears; colloidal systems such as milk, mayonnaise, paints, almost all cosmetics or body care products, the border lines between the different applications and systems are of course not sharp) or as biological molecules or assemblies (DNA, proteins, membranes and cytoskeleton, etc.) are central to our existence, others are basic ingredients of current and future high tech products (polymers with specific optical or electronic properties, conducting macromolecules, functional materials). Though the motivation is different in life science rather than in materials science biomolecular simulations, the basic structure of the problems faced in the two fields is very similar.

    2006-09-01

    We study QCD effects in single graviton production at the CERN Large Hadron Collider (LHC) in the Randall-Sundrum (RS) model. We present in detail the complete next-to-leading order (NLO) QCD corrections to the inclusive total cross sections. The NLO QCD corrections enhance significantly the total cross sections and decrease efficiently the dependence of the total cross sections on the factorization and renormalization scales. We also examine the uncertainty of the total cross sections due to the parton distribution function (PDF) uncertainties. For the differential cross sections on the transverse momentum (q{sub T}) of the graviton, within the CSS resummation formalism, we resum the logarithmically-enhanced terms at small q{sub T} to all orders up to NLO logatithmic accuracy. Combined with the fixed-order calculations, we give consistent predictions for both small q{sub T} and large q{sub T}.

    Marine and Earth Science graduates will be under increasing pressure in future to delve into research questions of relevance to societal challenges. Even fundamental research focused on basic processes of the environment and universe will in the coming decade need to justify their societal impact. As the Research Excellence Frameworks (REF) for research evaluation shift more and more away from the classical Impact Factor and number of peer-reviewed publications to "societal impact", the question remains whether the current graduates, and future researchers, are sufficiently prepared to deal with this reality. The essential compliment of skills beyond research excellence, rigor and method are traditionally described as "soft skills". This includes how to formulate an argument, how to construct a scientific publication, how to communicate such publications to non-experts, place them in context of societal challenges and relevant policies, how to write a competitive proposal and "market" one's research idea to build a research group around an interesting research topic. Such "soft skills" can produce very measurable and concrete impact for career development, but are rarely provided systematically and coherently by graduate schools in general. The presentation will focus on Open Science as a set of "soft skills", and demonstrate why graduate schools should train Open Science competencies alongside research excellence by default. Open Science is about removing all barriers to research process and outputs, both published and unpublished, and directly supports transparency and reproducibility of the research process. Open Science as a set of news competencies can also foster unexpected collaborations, engage citizen scientists into co-creation of solutions to societal challenges, as well as use concepts of Open Science to transfer new knowledge to the knowledge-based private sector, and help them with formulating more competitive research proposals in future.

    Secondary crystallization is the subject of much investigation in magnetic amorphous and nanocomposites (MANCs) as it limits the long term and thermal stability of their operation in device applications, including power electronics, sensors, and electric motors. Secondary crystal products [Blazquez et al., Philos. Mag. Lett. 82(7), 409–417 (2002); Ohodnicki et al., Phys. Rev. B 78, 144414 (2008); Willard et al., Metall. Mater. Trans.

Phys. 101, 09N114 (2007)] at constant heating have been reported for similar alloys. However, a time-temperature-transformation (TTT) diagram for isothermal crystallization, more typical of application environments, has not been reported in literature. Here, a TTT diagram for the Co based, Co-Fe-Si-Nb-B-Mn MANC system is presented, along with a method for determining such. The method accounts for the presence of primary crystal phases and yields crystal fraction of secondary phase(s) by using a novel four stage heating profile. The diagram, affirmed by Kissinger activation energy analysis, reports thermal stability of the MANC for millennia at conventional device operating temperatures, and stability limits less than a minute at elevated temperatures. Both extremes are necessary to be able to avoid secondary crystalline products and establish operating limits for this mechanically attractive, high induction soft magnetic nanocomposite.

  9. Soft selective sweeps in complex demographic scenarios.

    PubMed

    Wilson, Benjamin A; Petrov, Dmitri A; Messer, Philipp W

    2014-10-01

    Adaptation from de novo mutation can produce so-called soft selective sweeps, where adaptive alleles of independent mutational origin sweep through the population at the same time. Population genetic theory predicts that such soft sweeps should be likely if the product of the population size and the mutation rate toward the adaptive allele is sufficiently large, such that multiple adaptive mutations can establish before one has reached fixation; however, it remains unclear how demographic processes affect the probability of observing soft sweeps. Here we extend the theory of soft selective sweeps to realistic demographic scenarios that allow for changes in population size over time. We first show that population bottlenecks can lead to the removal of all but one adaptive lineage from an initially soft selective sweep. The parameter regime under which such "hardening" of soft selective sweeps is likely is determined by a simple heuristic condition. We further develop a generalized analytical framework, based on an extension of the coalescent process, for calculating the probability of soft sweeps under arbitrary demographic scenarios. Two important limits emerge within this analytical framework: In the limit where population-size fluctuations are fast compared to the duration of the sweep, the likelihood of soft sweeps is determined by the harmonic mean of the variance effective population size estimated over the duration of the sweep; in the opposing slow fluctuation limit, the likelihood of soft sweeps is determined by the instantaneous variance effective population size at the onset of the sweep. We show that as a consequence of this finding the probability of observing soft sweeps becomes a function of the strength of selection. Specifically, in species with sharply fluctuating population size, strong selection is more likely to produce soft sweeps than weak selection. Our results highlight the importance of accurate demographic estimates over short evolutionary timescales for understanding the population genetics of adaptation from de novo mutation. PMID:25060100

    Most news recommender systems try to identify users' interests and news' attributes and use them to obtain recommendations. Here we propose an adaptive model which combines similarities in users' rating patterns with epidemic-like spreading of news on an evolving network. We study the model by computer agent-based simulations, measure its performance and discuss its robustness against bias and malicious behavior. Subject to the approval fraction of news recommended, the proposed model outperforms the widely adopted recommendation of news according to their absolute or relative popularity. This model provides a general social mechanism for recommender systems and may find its applications also in other types of recommendation.

  7. Temporal and Cross Correlations in Business News

    NASA Astrophysics Data System (ADS)

    Mizuno, T.; Takei, K.; Ohnishi, T.; Watanabe, T.

    We empirically investigate temporal and cross correlations inthe frequency of news reports on companies, using a dataset of more than 100 million news articles reported in English by around 500 press agencies worldwide for the period 2003--2009. Our first finding is that the frequency of news reports on a company does not follow a Poisson process, but instead exhibits long memory with a positive autocorrelation for longer than one year. The second finding is that there exist significant correlations in the frequency of news across companies. Specifically, on a daily time scale or longer the frequency of news is governed by external dynamics, while on a time scale of minutes it is governed by internal dynamics. These two findings indicate that the frequency of news reports on companies has statistical properties similar to trading volume or price volatility in stock markets, suggesting that the flow of information through company news plays an important role in price dynamics in stock markets.

    This collection of snippets has as its theme the 1999 Solar Eclipse, and covers items that might be of interest to eclipse watchers and their associates. Much information can be obtained from the national web site at http://www.eclipse.org.uk. Set up by the CLRC Rutherford Appleton Laboratory, on behalf of the UK Eclipse Group, the site is intended to keep viewers abreast of developments during the countdown to the eclipse. The list of contents includes: about eclipses; eclipse pictures; eclipse science; safety advice; latest news; and local information. There is also a wealth of images and video footage, so the site has been organized with the visitor having a small PC and modem in mind, so that the key information can be accessed as quickly as possible. Free colour leaflets containing useful details for eclipse watchers can be obtained from the Particle Physics and Astronomy Research Council. `The Sun - our local star' and `Neutrinos' are additions to PPARC's series introducing key areas of its science. They answer such questions as what the Sun is, what eclipses are, why the Sun is important and where neutrinos come from. They support the National Curriculum Key Stages 3 and 4 plus A-level physics. The A5 leaflets open out into an A2 sized double-sided wall chart and bulk quantitites are available for class sets, visitor centres, exhibitions, open days etc. A full list of PPARC materials can be found at the website http://www.pparc.ac.uk or by order from Mark Wells, PPARC, Polaris House, North Star Avenue, Swindon SN2 1SZ (fax: 01793 442002).

  9. Sheet Bending using Soft Tools

    NASA Astrophysics Data System (ADS)

    Sinke, J.

    2011-05-01

    Sheet bending is usually performed by air bending and V-die bending processes. Both processes apply rigid tools. These solid tools facilitate the generation of software for the numerical control of those processes. When the lower rigid die is replaced with a soft or rubber tool, the numerical control becomes much more difficult, since the soft tool deforms too. Compared to other bending processes the rubber backed bending process has some distinct advantages, like large radius-to-thickness ratios, applicability to materials with topcoats, well defined radii, and the feasibility of forming details (ridges, beads). These advantages may give the process exclusive benefits over conventional bending processes, not only for industries related to mechanical engineering and sheet metal forming, but also for other disciplines like Architecture and Industrial Design The largest disadvantage is that also the soft (rubber) tool deforms. Although the tool deformation is elastic and recovers after each process cycle, the applied force during bending is related to the deformation of the metal sheet and the deformation of the rubber. The deformation of the rubber interacts with the process but also with sheet parameters. This makes the numerical control of the process much more complicated. This paper presents a model for the bending of sheet materials using a rubber lower die. This model can be implemented in software in order to control the bending process numerically. The model itself is based on numerical and experimental research. In this research a number of variables related to the tooling and the material have been evaluated. The numerical part of the research was used to investigate the influence of the features of the soft lower tool, like the hardness and dimensions, and the influence of the sheet thickness, which also interacts with the soft tool deformation. The experimental research was focused on the relation between the machine control parameters and the most dominant output parameter, the product angle. The numerical analyses are used for the support of the experimental results.

  13. Soft Pion Processes

    DOE R&D Accomplishments Database

    Nambu, Y.

    1968-01-01

    My talk is concerned with a review, not necessarily of the latest theoretical developments, but rather of an old idea which has contributed to recent theoretical activities. By soft pion processes I mean processes in which low energy pions are emitted or absorbed or scattered, just as we use the word soft photon in a similar context. Speaking more quantitatively, we may call a pion soft if its energy is small compared to a natural scale in the reaction. This scale is determined by the particular dynamics of pion interaction, and one may roughly say that a pion is soft if its energy is small compared to the energies of the other individual particles that participate in the reaction. It is important to note at this point that pion is by far the lightest member of all the hadrons, and much of the success of the soft pion formulas depends on this fact.

  18. Double soft theorems in gauge and string theories

    NASA Astrophysics Data System (ADS)

    Volovich, Anastasia; Wen, Congkao; Zlotnikov, Michael

    2015-07-01

    We investigate the tree-level S-matrix in gauge theories and open superstring theory with several soft particles. We show that scattering amplitudes with two or three soft gluons of non-identical helicities behave universally in the limit, with multi-soft factors which are not the product of individual soft gluon factors. The results are obtained from the BCFW recursion relations in four dimensions, and further extended to arbitrary dimensions using the CHY formula. We also find new soft theorems for double soft limits of scalars and fermions in and pure SYM. Finally, we show that the double-soft-scalar theorems can be extended to open superstring theory without receiving any ?' corrections.

    It is estimated that more than 40% of new chemical entities (NCEs) coming out of the current drug discovery process have poor biopharmaceutical properties, such as low aqueous solubility and/or permeability. These suboptimal properties pose significant challenges for the oral absorption of the compounds and for the development of orally bioavailable dosage forms. Development of soft gelatin capsule (softgel) dosage form is of growing interest for the oral delivery of poorly water soluble compounds (BCS class II or class IV). The softgel dosage form offers several advantages over other oral dosage forms, such as delivering a liquid matrix designed to solubilize and improve the oral bioavailability of a poorly soluble compound as a unit dose solid dosage form, delivering low and ultra-low doses of a compound, delivering a low melting compound, and minimizing potential generation of dust during manufacturing and thereby improving the safety of production personnel. However, due to the very dynamic nature of the softgel dosage form, its development and stability during its shelf-life are fraught with several challenges. The goal of the current review is to provide an in-depth discussion on the softgel dosage form to formulation scientists who are considering developing softgels for therapeutic compounds.

    2011-03-01

    Social media are revolutionizing the ways that people communicate and the ways they get their news. Traditional news outlets are in decline, and no subject area is declining faster than science news. Every day there are fewer professional science journalists working in traditional media. On the other hand, ever greater numbers of scientists, science enthusiasts, and online journalists are turning to blogs, podcasts, eBooks, twitter feeds, and social media sites like Facebook and Tumbler to spread news about science. I will present an overview of the state of science journalism and speculate on the likely directions it seems to be heading. I will also offer some general guidelines to help scientists understand what makes a good science news story, as well as suggesting ways that they can get their work in the news.

    Supplementary Materials The number of supplementary materials that accompany print articles has grown and also become more varied. The new guidelines for lab experiments call for supplementary materials in most cases, so that the actual materials used in lab can be made available. The From Past Issues column edited by Kathryn Williams and many of the technology columns frequently have supplements for JCE Online. An especially interesting supplement that we would like to call to the attention of readers is a collection of videos from the E. O. Lawrence Berkeley National Laboratory, based on interviews with nuclear chemists who have discovered and studied the heaviest elements. These movies accompany the Viewpoints article, "Chemistry of the Heaviest Elements-One Atom at a Time" by Darleane C. Hoffman and Diana M. Lee. The titles of the movies are listed below; illustrative stills are shown at the bottom of the page. Researchers involved with the segments about Lawrencium include Robert Silva, Torbjorn Sikkeland, Matti Nurmia, Robert Latimer, and Albert Ghiorso, all of whom are from the Lawrence Berkeley Laboratory.

People: Glenn Seaborg Glenn Seaborg, frequent contributor and faithful supporter of this Journal, died February 25, 1999, at his home in Lafayette, California, at the age of 86. At the Fall 1998 ACS Meeting in Boston he suffered a serious fall following a stroke, from which he never recovered. One of his last photographs, taken the previous day at a Journal luncheon, appears on page 1360 of the November 1998 issue. His commentary on his long career in chemistry and education appears on page 1520 of the December 1998 issue. Seaborg was a Nobel laureate, discoverer of elements, scientific advisor to presidents, former chancellor of the University of California, former chairman of the Atomic Energy Commission, chairman of the steering committee of the CHEM Study project, founder of Lawrence Hall of Science, , the list goes on and on. He was at the same time a passionate supporter of education. Seaborg published fourteen articles in the Journal between 1951 and 1998. He was interviewed in 1975 by David Ridgway as part of the Impact series (JCE 1975, 52, 70), and that interview is highly recommended reading (see supplement to this article). He received the 1994 ACS George C. Pimentel Award in Chemical Education; his award address was published in the ACS Division of Chemical Education's CHED Newsletter, Fall 1995. Memorial articles with details of his life and his scientific contributions have appeared in The New York Times (Saturday, February 27, 1999, page 1) and Chemical & Engineering News (March 8, 1999, page 29). But there is also the spirit of the man, what he believed in, what he tried to do, what he hoped he had accomplished. A sense of that can be gained from the excerpts that are reprinted below, taken first from the Impact interview and then from the award address. Ridgway: On reflection, now, out of your many contributions to chemistry, is there one that you feel has had more of an impact than others? Seaborg: The discovery of plutonium would answer that question. The impact there is probably nearly as great as any single chemical discovery. Ridgway: What was the state of the "art" in your field when you first decided to bend your energies in this direction? Seaborg: In nuclear science? Very crude. I mean we had difficulty even making the simplest Geiger counter work. This facet alone was always a challenge. Ridgway: What do you look for in a young person who wishes to work with you in your research program? Seaborg: Certainly I try to identify intelligence and creativity and very importantly, industry, that is the willingness to work hard which leads to dedication. Ridgway: ...research and teaching or research versus teaching. Do you consider in your own pursuits in the academic life a dichotomy between teaching and research? Seaborg: Definitely not! I think they go together very well. I teach freshman chemistry and it's a joy to meet my freshman chemistry sections. It gives me a better perspective even though it's at the beginning level. In addition, the fact that I'm conducting research helps (in my opinion) freshman chemistry. As your readers well know, freshman chemistry is a sophisticated and complicated subject these days. Pimentel Award Address: Regarding the CHEM Study project: Although my heavy schedule as Chancellor of the University of California, Berkeley, and numerous other commitments should have made me decline this added responsibility, the unusual circumstances of our meeting and the ardor of the group led to my somewhat bewildered acceptance. Report of the National Commission on Excellence in Education (1983): If an unfriendly foreign power had attempted to impose on America the mediocre educational performance that exists today, we might well have viewed it as an act of war. As it stands, We have allowed this to happen to ourselves Discussing Great Explorations in Math and Science (GEMS): It is an unfortunate fact, borne out by research and much anecdotal experience, that by the time they reach high school most students have already decided whether or not they like chemistry, and whether or not they are good at it. In Summary: Having served in many capacities, educational and governmental over my career, I have no illusions about the complexities involved in implementing change. Yet there is really no choice if we are to survive and thrive as a nation. We must shine a strong spotlight on education, with special and lasting emphasis on science and technology, and the real-world connections so apparent to us in chemistry and all the sciences.

The database includes public and private courses at all levels from more than 15 countries and includes only those courses that can be completed fully online. Courses vary from graduate-level engineering offerings to simple "How to" courses. The database provides access to courses and programs leading to accredited degrees, diplomas, and certificates. Professional development and personal interest courses are also included. Students can access course information by browsing subject areas or by searching specific fields. Hotlinks connect students directly to the delivering institutions. In the past year, there has been an exponential rise in the number of courses being offered online, from fewer than 2,000 in January 1998 to more than 10,000 in December 1998. It is expected that there will be more than 40,000 online courses by the year 2000. The TeleCampus Online Course Database provides students with a means of finding information on courses that meet their needs. The database can be accessed from TeleCampus at http://telecampus.edu. Change in the Introductory Chemistry Course, an Online Course An online conference, Proposals for Change in the Introductory Chemistry Course, will take place from March 29 to April 10, 1999. The conference will be chaired by James N. Spencer, Chemistry Department, Franklin & Marshall College, Lancaster, PA 17604; j_spencer@acad.fandm.edu. While both process and content need to be considered in making changes, this conference will be limited to a discussion of content. It will take the approach that if we begin to examine the current content and how and why certain topics came to be considered as essential for the course, we may be able to approach a common curriculum so that the process of how to best to implement it may then be developed. Stephen J. Hawkes of Oregon State University compiled suggestions for the content of general chemistry and served as leader of the Zero Base Course discussion group for the Task Force on the General Chemistry Curriculum. The goal of the zero base approach is a detailed curriculum in which topics are developed so that students understand the phenomena considered necessary for the course. This analysis requires that the principles that should be in the course be identified, that those not necessary be removed, and perhaps additional principles be added. This online conference will list more than 100 proposals compiled from many viewpoints. Proposals are worded as debatable propositions to engender serious discussion. After discussion, amendment, deletion, extension, and some consensus, the proposals will be distributed to the chemistry community in various forms. Future discussions are also planned.

It was written as a step-by-step guide to solving routine crystal structures for crystallographic novices and is entitled "Allen Hunter's Youngstown State University X-ray Structure Analysis Lab Manual: A Beginner's Introduction". The manual has been developed in an undergraduate course that enrolls a broad mixture of chemists, engineers, geologists, and biologists. It is optimized for use with the SHELXTL suite of programs but should prove useful to those using other structure solution packages as well. This edition has been reviewed at twelve sites and will be available for general use in January 1999. The lab manual is available without charge as a .pdf file to academic users, provided that each copy is registered and users inform the author about how it is used in their teaching.

    This manuscript describes a unique class of locomotive robot: A soft robot, composed exclusively of soft materials (elastomeric polymers), which is inspired by animals (e.g., squid, starfish, worms) that do not have hard internal skeletons. Soft lithography was used to fabricate a pneumatically actuated robot capable of sophisticated locomotion (e.g., fluid movement of limbs and multiple gaits). This robot is quadrupedal; it uses no sensors, only five actuators, and a simple pneumatic valving system that operates at low pressures (<10psi). A combination of crawling and undulation gaits allowed this robot to navigate a difficult obstacle. This demonstration illustrates an advantage of soft robotics: They are systems in which simple types of actuation produce complex motion. PMID:22123978

    2014-01-01

    The notion of fuzzy soft sets is a hybrid soft computing model that integrates both gradualness and parameterization methods in harmony to deal with uncertainty. The decomposition of fuzzy soft sets is of great importance in both theory and practical applications with regard to decision making under uncertainty. This study aims to explore decomposition of fuzzy soft sets with finite value spaces. Scalar uni-product and int-product operations of fuzzy soft sets are introduced and some related properties are investigated. Using t-level soft sets, we define level equivalent relations and show that the quotient structure of the unit interval induced by level equivalent relations is isomorphic to the lattice consisting of all t-level soft sets of a given fuzzy soft set. We also introduce the concepts of crucial threshold values and complete threshold sets. Finally, some decomposition theorems for fuzzy soft sets with finite value spaces are established, illustrated by an example concerning the classification and rating of multimedia cell phones. The obtained results extend some classical decomposition theorems of fuzzy sets, since every fuzzy set can be viewed as a fuzzy soft set with a single parameter. PMID:24558342

    Three-dimensional (3D) printing is advantageous over conventional technologies for the fabrication of sophisticated structures such as 3D micro-channels for future applications in tissue engineering and drug screening. We aimed to apply this technology to cell-based assays using polydimethylsiloxane (PDMS), the most commonly used material for fabrication of micro-channels used for cell culture experiments. Useful properties of PDMS include biocompatibility, gas permeability and transparency. We developed a simple and robust protocol to generate PDMS-based devices using a soft lithography mold produced by 3D printing. 3D chemical gradients were then generated to stimulate cells confined to a micro-channel. We demonstrate that concentration gradients of growth factors, important regulators of cell/tissue functions in vivo, influence the survival and growth of human embryonic stem cells. Thus, this approach for generation of 3D concentration gradients could have strong implications for tissue engineering and drug screening. PMID:25686903

    The functions of soft robotics are intimately tied to their form-channels and voids defined by an elastomeric superstructure that reversibly stores and releases mechanical energy to change shape, grip objects, and achieve complex motions. Here, we demonstrate that covalent polymer mechanochemistry provides a viable mechanism to convert the same mechanical potential energy used for actuation in soft robots into a mechanochromic, covalent chemical response. A bis-alkene functionalized spiropyran (SP) mechanophore is cured into a molded poly(dimethylsiloxane) (PDMS) soft robot walker and gripper. The stresses and strains necessary for SP activation are compatible with soft robot function. The color change associated with actuation suggests opportunities for not only new color changing or camouflaging strategies, but also the possibility for simultaneous activation of latent chemistry (e.g., release of small molecules, change in mechanical properties, activation of catalysts, etc.) in soft robots. In addition, mechanochromic stress mapping in a functional robotic device might provide a useful design and optimization tool, revealing spatial and temporal force evolution within the robot in a way that might be coupled to autonomous feedback loops that allow the robot to regulate its own activity. The demonstration motivates the simultaneous development of new combinations of mechanophores, materials, and soft, active devices for enhanced functionality. PMID:26390078

    Delcam, a manufacturing software developer, has supplied substantial funding towards a UK Government initiative intended to revolutionize the study of design and technology in schools. The computer-aided design software for schools (CAD-CAM) programme will give students a bridge into industry by enabling them to employ video links with engineers at companies such as British Aerospace and Rolls Royce. They will then be able to convert their virtual reality designs into a finished product. When the revised National Curriculum comes into effect this year, CAD-CAM will become compulsory from Key Stage 3, reflecting the greater focus on work-related learning, as well as the added importance being given to Information and Communications Technology (ICT) within the curriculum. Under the new scheme, schools can use a range of software designed in the UK (currently used for such items as jet aircraft and Formula One racing cars), which is being made available free of charge. The Design and Technology Association is monitoring the programme and the schools taking part have had to propose targets, focused on curriculum innovation, pupil outcomes and staff development. Still on the theme of design is the `Young Foresight' project launched in January and inviting 13 to 14 year-olds to tackle the challenges of the future through designing a new product for the world of 2020. The aim here is to encourage creativity, enterprise and innovation among young people by giving them an idea of what is involved in the design and development of a successful product. The students will be supported by mentors drawn from the local business community and there will be related BBC schools television programmes early in March with classroom resources, teacher training and an interactive website. The first phase of the initiative, based on 100 schools from across England and Wales, should be completed by autumn 2000, with phase 2 for 3000 schools over a three-year period incorporating a further nine programmes reflecting the work of the national Foresight Panels. The national Foresight programme is about preparing for the future by identifying market drivers, threats and opportunities and using that knowledge to inform the decisions that need to be taken today. Details can be viewed at www.foresight.gov.uk And for those with any remaining untapped ingenuity, the deadline is fast approaching for this year's `Young Engineer for Britain' competition. Young people, either individually or in teams of up to four, are invited to demonstrate their engineering skills in an event with a total prize value of over £65 000. The individual winner takes away a personal prize of £2500 plus a trophy, and their school receives an additional £2500 for engineering teaching equipment. Entry details can be obtained from Young Engineers for Britain, Engineering Council, 10 Maltravers Street, London WC2R 3ER and the closing date is 28 April 2000 .

    In contrast to the hard lenses the soft lens has enough permeability for oxygen and water-soluble substances, whereas high molecular substances, bacteria and virus cannot penetrate the soft lenses, so long as their surfaces are intact. The two principal production methods, the spin cast method and the lathe-turned method are compared. The duration of wearing of the soft lens depends on the deposits of proteins from the tears on the surface of the lens and the desinfection method. The daily boiling of the lenses shortens their useful life, while chemical desinfection causes besides bacteriolysis, damage of the corneal cell protein. The new cleaners on the base of proteolytic plant enzymes promise good results. For the optical correction of astigmatism with more than 1 cyl, soft lenses with conic outer surface are used or combinations of a soft and a hard lens (Duosystem). The therapeutic use of soft lenses has as aim: protection of the cornea against mechanical irritation, release of pain, protracted administration output of medicaments. Further indications for use: aseptic corneal inflammation and corneal defects. PMID:1202269

    Interval-valued fuzzy soft sets realize a hybrid soft computing model in a general framework. Both Molodtsov's soft sets and interval-valued fuzzy sets can be seen as special cases of interval-valued fuzzy soft sets. In this study, we first compare four different types of interval-valued fuzzy soft subsets and reveal the relations among them. Then we concentrate on investigating some nonclassical algebraic properties of interval-valued fuzzy soft sets under the soft product operations. We show that some fundamental algebraic properties including the commutative and associative laws do not hold in the conventional sense, but hold in weaker forms characterized in terms of the relation = L . We obtain a number of algebraic inequalities of interval-valued fuzzy soft sets characterized by interval-valued fuzzy soft inclusions. We also establish the weak idempotent law and the weak absorptive law of interval-valued fuzzy soft sets using interval-valued fuzzy soft J-equal relations. It is revealed that the soft product operations ? and ? of interval-valued fuzzy soft sets do not always have similar algebraic properties. Moreover, we find that only distributive inequalities described by the interval-valued fuzzy soft L-inclusions hold for interval-valued fuzzy soft sets. PMID:25143964

    Support for astronomy in A-level physics aslogo Help is at hand for teachers and students choosing astronomy as part of A-level physics. The Teaching Resources Unit for Modern Physics (TRUMP) has produced a resource package covering all the astronomical options in the Edexcel, OCR and AQA (NEAB) syllabuses. The forerunner to TRUMP was the project that produced the highly successful Particle Physics Pack, sponsored by the Institute of Physics, which was instrumental in introducing particle physics into A-level syllabuses. The TRUMP Astrophysics Resource Package fills a gap between the colourful stimulus of popular materials on the one hand, and professional texts on the other. But this is not just another A-level textbook; the six-part resource pack has a similar structure and purpose to the Particle Physics Pack. It provides over 400 pages of comprehensive information for teachers, building on their existing subject knowledge and bringing them up to date as well as giving suggestions for teaching and notes on syllabus coverage. The package includes nearly 40 photocopiable sheets for students. The emphasis is on the physics that underpins the astronomy. There are details of student activities requiring no specialist equipment beyond that normally found in A-level labs, exercises using authentic data, and plenty of questions (all with worked solutions). The development of the TRUMP Astrophysics Package was funded by the Nuffield Foundation, the Particle Physics and Astronomy Research Council, the Institute of Physics and York University. The package is available by mail order, price £48 (inc. UK p&p) from the TRUMP Project, Science Education Group, University of York, Heslington, York YO10 5DD. Some parts may be purchased separately; for details contact the project's director, Elizabeth Swinbank (tel: 01904 434537, fax: 01904 434078, e-mail: es14@york.ac.uk) or consult the web page www.york.ac.uk/org/seg/trump. The BaBar experiment balogo In the spring of 1999, scientists began to collect data from the BaBar experiment - an international collaboration involving the UK, several other European countries and the USA. The experiment is designed to throw light on the puzzling question of why there is so little antimatter in the universe and so much matter. The TRUMP BaBar resource package brings the mystery of antimatter into schools. There are notes and colourful posters on the physics of BaBar, and photocopiable sheets supporting student activities. These include explorations of symmetry, templates for making a scale model of the BaBar detector, and a web-based research project. The pack is designed mainly for A-level physics (particularly those courses that include some particle physics) but parts also relate to GCSE science, Scottish Higher physics and Standard physics. The BaBar resource package is available free from the Particle Physics and Astronomy Research Council, which fully funded its development and production.

    Classroom Activities Mean Teamwork As much as any other facet of the editing and production of the Journal, the Classroom Activity series means teamwork! The aim is for activities to be interesting and accessible to introductory students, based on inexpensive and readily available materials, connected by content to some part of the Journal issue, able to be integrated into the high school curriculum, and safe. There need to be questions posed and answers at the ready. Additional information in print and on the Web needs to be identified and checked. The activities are designed to be ready for teachers to hand to students, so they really need to work-that means that they go through a lot of testing in Journal House where there is, quite fittingly, no lab. This is a tall order, one requiring someone with experience in high school teaching. From the start of the Activities in September 1997, Nancy Gettys has had a major role in their success. While Nancy's primary responsibility is as the Technical Editor of JCE Software, she has experience in teaching high school and has called on that experience to try and test, expand, try again, plan the illustrations (remember the photographs of the activities with surface phenomena that were featured in the table of contents of the February 1998 issue?), and perhaps hardest of all-tell us when something will just not work in high school. Nancy continues to work with the Classroom Activities, but she now has a colleague in fellow high school teacher Erica Jacobsen who has recently joined our staff. Introducing... Erica Jacobsen joined our staff last fall as an editorial assistant and has recently become an assistant editor. She received her undergraduate degree in education from the University of Wisconsin-Madison. Her teaching licenses include certifications in chemistry, physics, biology, and natural science for grades six through twelve. During her undergraduate years, she worked with the Chemical Education Group. Her undergraduate research and senior thesis were directed by John W. Moore and centered on the subject of HIV and its use as a topic in the chemistry curriculum. The research culminated in writing and publishing "HIV-1 Protease: An Enzyme at Work," a videotape and teacher/student guide offered by the Journal of Chemical Education Software. After graduation, Erica taught chemistry, AP chemistry, and physics for two years at a rural public high school in Minnesota. During her teaching, as a reader of the Journal, she was delighted to see the introduction of the Classroom Activities feature. She found the ready-made activities a great complement to her "hands-on, minds-on" curriculum. Due to her husband's job transfer, she has returned to Madison and is even more delighted to now be a part of the development of Classroom Activities. Her duties at Journal House include helping to test, research, and write Classroom Activities. She divides her time between working at Journal House, taking additional science coursework at the university for professional development, and tutoring chemistry students. She is settling in to her new life in Madison and she and her husband enjoy exploring the Wisconsin outdoors together.

    2011-09-01

    In financial markets, he behavior of investors determines the prices of financial products. However, these investors can also be influenced by good and bad news. Here, we present a mathematical model to reproduce the price dynamics in real financial markets affected by news. The model has both positive and negative feed-back mechanisms. Furthermore, the behavior of the model is examined by considering two different types of noise. Our results show that the dynamic balance of positive and negative feed-back mechanisms with the noise effect determines the asset price movement. For comparison with real market, we have used the Forex data corresponding to the time period of the recent Tohoku-Kanto earthquake in Japan.

  9. Mediating subpolitics in US and UK science news.

    PubMed

    Jensen, Eric

    2012-01-01

    The development of therapeutic cloning research sparked a scientific controversy pitting patients' hopes for cures against religious and anti-abortion opposition. The present study investigates this controversy by examining the production and content of Anglo-American print media coverage of the branch of embryonic stem cell research known as "therapeutic cloning." Data collection included press articles about therapeutic cloning (n = 5,185) and qualitative interviews with journalists (n = 18). Patient activists and anti-abortion groups emerged as key news sources in this coverage. Significant qualitative differences in the mediation of these subpolitical groups and their arguments for and against therapeutic cloning are identified. Results suggest that the perceived human interest news value of narratives of patient suffering may give patient advocacy groups a privileged position in journalistic coverage. Finally, Ulrich Beck's theoretical arguments about subpolitics are critically applied to the results to elicit further insights. PMID:22530488

  10. NEWS: GIREP in Barcelona

    NASA Astrophysics Data System (ADS)

    Dobson, Ken

    2000-11-01

    The 18th biannual conference of GIREP was held in Barcelona from 27 August to 1 September 2000. GIREP stands for Groupe International de Recherche sur l'Enseignement de la Physique. Some 400 delegates from 53 countries attended the conference, whose main concern was Physics Teacher Education beyond 2000. All contributions had to made in English. A conference like this needs to be singularly interesting to keep delegates away from the sunsoaked attractions and delights of one of the most exciting cities in the world - even if some of the excitement comes from wondering whether or not you are going to get your pocket picked. A typical conference day begins with two or three plenary lectures in the morning, with the afternoon given over to a set of nine parallel sessions. These sessions consisted of tightly timetabled 20 minute talks or other types of presentation. This meant that even the most dedicated delegate could get to little more than 10% of the over 200 sessions that were on offer in the afternoons. The event was organized by Catalonian locals working at the conference site, the Universitat Autonoma de Barcelona, and was superbly smooth. The list of organizations supporting the conference is too long to record, but ranged from the European Commission to Barcelona Science Museum. The UK can boast (if that is the right word) just 11 paid-up members of GIREP, which at about £10 per annum is hardly an expensive club - next year it goes up to 20 Euros - and the fee is worth it for the excellently produced book or CD-ROM of the conference proceedings. These contain a great deal of wisdom, plus the fair amount of infuriating rubbish that tends to be generated by educational research. I write here with all the prejudices of an aged ex-teacher, of course. The first morning lecture was given by Jon Ogborn, who used his recent work as organizer of the IoP post-16 Initiative to give some details of the Advancing Physics AS and A2 and make some general points about designing a new curriculum in Physics. His main argument perhaps was that a physics course should be designed as a set of narratives, with beginning, middle, end and a point, rather than as a set of concepts whose meaning was of more significance to the teacher or curriculum designer than to the students. He was followed by Ed Redish of the University of Maryland, another entertaining speaker who addressed the global problem of the decline in the number of students willing to study physics when given a free choice not to do so. His talk was wide ranging, but centred on the apparent fact that physics teaching was essentially unsuccessful - for a variety of reasons. He proposed that this was a problem that could and should be tackled scientifically, with a loop of research-instruction-design. Science is good at solving problems, but so far physics hasn't seen physics teaching and learning as problematic. Maybe physics lecturers are so good at physics that difficulty in learning it is taken to be a student problem (inattention, sheer stupidity) rather than a systemic one. I look forward to hearing more about this. What I did get from one or two lectures about research into the way teachers failed tended to raise my blood pressure to dangerous levels. In both cases considerable skill and effort had been put into finding out that curriculum innovations or new teaching techniques had been badly handled by teachers, who had still kept to their old ways - like using ray boxes in optics work, or failing to make best use of Real Time laboratory systems (i.e. data logging). These new approaches were described as expert-designed innovations. I am afraid that it occurred to me that if experts had been employed to produce a new production system in a factory failure of the workforce to implement it would have resulted in some high-level expert redundancies. Certainly not `more research' as was advocated here. But it wasn't all grief: many talks and lectures were inspiring and showed how many people across the world were working hard and intelligently to improve physics teaching - all for the benefit of learners. It occurred to me too how lucky we are in UK to be at the forefront of so much of this, and usually in a practical and pragmatic way that emphasizes the importance - the absolute necessity - of teachers being fully involved in any development that has a strong likelihood of success. Other countries, especially in Italy and France, seem to be just cottoning on to the need for more thoughtful practical work, the need for smart use of ICT, investigations etc. The UK does well here, partly because of and partly in spite of a strong and increasingly centrally determined curriculum and pedagogy. Some highlights: Ed Taylor (MIT, his website is www.eftaylor.com) made a lightning 20 minute raid on conventional physics teaching, i.e. Newton etc, cutting out the concept of force, F = ma, and replacing this with relativity and the Feynman Many Paths model of quantum physics as introductory topics. All the rest of physics follows naturally and coherently. This radical attack was closely followed by our own Ian Lawrence (now at Birmingham University) giving a concise and cogent demonstration of how Many Paths is taught in Advancing Physics (see the article on pages 400-405 of this issue). Brian Woolnough (Oxford University Department of Education) came down to earth with a nice talk about how teachers and ordinary PGCE students benefited from small educational research projects. Richard Gunstone (Monash University) gave a funny but fundamentally serious account of how bad things were in Australia, blaming Physics lecturers mostly, but making good points too about how other beginning professionals have different expectations and support systems from beginning teachers. I shall leave out the lowlights. I could go on. I could have chosen other talks to go to and been better or worse off. But the weather was hot and sunny, my pocket wasn't picked, transport, food and drink were cheap and there were lots of people to talk to. The conference dinner was at the Barcelona Ritz. The next GIREP conference will be at Lund University, Sweden, in early August 2002. Check out the website: www.blues.uab.es/phyteb

  11. Quality of health news disseminated in the print media in developing countries: a case study in Iran

    PubMed Central

    2012-01-01

    Background Mass media play an important role in keeping people up-to-date with the latest health news. This study aims at investigating the quality of health news disseminated in the print media, its course of production and factors affecting its quality. Methods In the quantitative section of the study, 410 health-related news items, published during a six-month span in the Iranian public press, underwent content analysis. In the qualitative section, focus group discussions were held with journalists, editors-in-chief and news gatekeepers. Results The quantitative phase showed that 18% of the news articles were not fit for dissemination in public. The qualitative phase illustrated that multiple factors at various levels affect the quality of news, namely poor knowledge, inadequate motivations and context-related barriers. Conclusions The quality of health news reporting is not desirable. Educational interventions need to be carried out to raise awareness among researchers and journalists. Also, certain steps should be taken to increase motivations and strengthen infrastructures, including designing guidelines and monitoring news. PMID:22873836

  12. Soft drinks in schools.

    PubMed

    2004-01-01

    This statement is intended to inform pediatricians and other health care professionals, parents, superintendents, and school board members about nutritional concerns regarding soft drink consumption in schools. Potential health problems associated with high intake of sweetened drinks are 1) overweight or obesity attributable to additional calories in the diet; 2) displacement of milk consumption, resulting in calcium deficiency with an attendant risk of osteoporosis and fractures; and 3) dental caries and potential enamel erosion. Contracts with school districts for exclusive soft drink rights encourage consumption directly and indirectly. School officials and parents need to become well informed about the health implications of vended drinks in school before making a decision about student access to them. A clearly defined, district-wide policy that restricts the sale of soft drinks will safeguard against health problems as a result of overconsumption. PMID:14702469

  14. Space Shuttle Status News Conference

    NASA Technical Reports Server (NTRS)

    2005-01-01

    Richard Gilbech, External Tank "Tiger Team" Lead, begins this space shuttle news conference with detailing the two major objectives of the team. The objectives include: 1) Finding the root cause of the foam loss on STS-114; and 2) Near and long term improvements for the external tank. Wayne Hale, Space Shuttle Program Manager, presents a chart to explain the external tank foam loss during STS-114. He gives a possible launch date for STS-121 after there has been a repair to the foam on the External Tank. He further discusses the changes that need to be made to the surrounding areas of the plant in New Orleans, due to Hurricane Katrina. Bill Gerstemaier, NASA Associate Administrator for Space Operations, elaborates on the testing of the external tank foam loss. The discussion ends with questions from the news media about a fix for the foam, replacement of the tiles, foam loss avoidance, the root cause of foam loss and a possible date for a new external tank to be shipped to NASA Kennedy Space Center.

  15. The NEWS Water Cycle Climatology

    Rodell, Matthew; Beaudoing, Hiroko Kato; L'Ecuyer, Tristan; William, Olson

    2012-01-01

    NASA's Energy and Water Cycle Study (NEWS) program fosters collaborative research towards improved quantification and prediction of water and energy cycle consequences of climate change. In order to measure change, it is first necessary to describe current conditions. The goal of the first phase of the NEWS Water and Energy Cycle Climatology project was to develop "state of the global water cycle" and "state of the global energy cycle" assessments based on data from modern ground and space based observing systems and data integrating models. The project was a multi-institutional collaboration with more than 20 active contributors. This presentation will describe the results of the water cycle component of the first phase of the project, which include seasonal (monthly) climatologies of water fluxes over land, ocean, and atmosphere at continental and ocean basin scales. The requirement of closure of the water budget (i.e., mass conservation) at various scales was exploited to constrain the flux estimates via an optimization approach that will also be described. Further, error assessments were included with the input datasets, and we examine these in relation to inferred uncertainty in the optimized flux estimates in order to gauge our current ability to close the water budget within an expected uncertainty range.

  16. Some properties of fuzzy soft proximity spaces.

    PubMed

    Demir, İzzettin; Özbakır, Oya Bedre

    2015-01-01

    We study the fuzzy soft proximity spaces in Katsaras's sense. First, we show how a fuzzy soft topology is derived from a fuzzy soft proximity. Also, we define the notion of fuzzy soft δ-neighborhood in the fuzzy soft proximity space which offers an alternative approach to the study of fuzzy soft proximity spaces. Later, we obtain the initial fuzzy soft proximity determined by a family of fuzzy soft proximities. Finally, we investigate relationship between fuzzy soft proximities and proximities. PMID:25793224

  17. Asymptotic symmetries and subleading soft graviton theorem

    NASA Astrophysics Data System (ADS)

    Campiglia, Miguel; Laddha, Alok

    2014-12-01

    Motivated by the equivalence between the soft graviton theorem and Ward identities for the supertranslation symmetries belonging to the Bondi, van der Burg, Metzner and Sachs (BMS) group, we propose a new extension (different from the so-called extended BMS) of the BMS group that is a semidirect product of supertranslations and Diff(S2) . We propose a definition for the canonical generators associated with the smooth diffeomorphisms and show that the resulting Ward identities are equivalent to the subleading soft graviton theorem of Cachazo and Strominger.

  7. Nanobiotechnology: soft lithography.

    PubMed

    Mele, Elisa; Pisignano, Dario

    2009-01-01

    An entirely new scientific and technological area has been born from the combination of nanotechnology and biology: nanobiotechnology. Such a field is primed especially by the strong potential synergy enabled by the integration of technologies, protocols, and investigation methods, since, while biomolecules represent functional nanosystems interesting for nanotechnology, micro- and nano-devices can be very useful instruments for studying biological materials. In particular, the research of new approaches for manipulating matter and fabricating structures with micrometre- and sub-micrometre resolution has determined the development of soft lithography, a new set of non-photolithographic patterning techniques applied to the realization of selective proteins and cells attachment, microfluidic circuits for protein and DNA chips, and 3D scaffolds for tissue engineering. Today, soft lithographies have become an asset of nanobiotechnology. This Chapter examines the biological applications of various soft lithographic techniques, with particular attention to the main general features of soft lithography and of materials commonly employed with these methods. We present approaches particularly suitable for biological materials, such as microcontact printing (muCP) and microfluidic lithography, and some key micro- and nanobiotechnology applications, such as the patterning of protein and DNA microarrays and the realization of microfluidic-based analytical devices.

    2010-01-01

    The shift toward viewing patients as active consumers of health information raises questions about whether individuals respond to health news by seeking additional information. This study examines the relationship between cancer news coverage and information seeking using a national survey of adults aged 18 years and older. A Lexis-Nexis database search term was used to identify Associated Press (AP) news articles about cancer released between October 21, 2002, and April 13, 2003. We merged these data to the Health Information National Trends Survey (HINTS), a telephone survey of 6,369 adults, by date of interview. Logistic regression models assessed the relationship between cancer news coverage and information seeking. Overall, we observed a marginally significant positive relationship between cancer news coverage and information seeking (p < 0.07). Interaction terms revealed that the relationship was apparent only among respondents who paid close attention to health news (p < 0.01) and among those with a family history of cancer (p < 0.05). Results suggest that a notable segment of the population actively responds to periods of elevated cancer news coverage by seeking additional information, but they raise concerns about the potential for widened gaps in cancer knowledge and behavior between large segments of the population in the future.

    "Noticias del Cosmos" (News from the Cosmos) is a web page devoted to the news and press releases published daily on the web about astronomical discoveries and space missions. The discussion about recent pieces of news is a good way to introduce astronomy lessons in school, keeping the sense of discovery alive among the students, who too often think of school subjects as static matters with no or very little relationship to their everyday lives. In order to facilitate the access to the news to Spanish speaking students and teachers, who usually develop their teaching activities only in Spanish, we decided to publish the news abstracts in Spanish with links to the original (almost always in English) piece of news.

  14. Soft interactions in jet quenching

    NASA Astrophysics Data System (ADS)

    Hidalgo-Duque, Carlos; Llanes-Estrada, Felipe J.

    2015-04-01

    We study the collisional aspects of jet quenching in a high-energy nuclear collision, especially in the final state pion gas. The jet has a large energy, and acquires momentum transverse to its axis more effectively by multiple soft collisions than by few hard scatterings (as known from analogous systems such as J/ψ production at Hera). Such regime of large E and small momentum transfer corresponds to Regge kinematics and is characteristically dominated by the pomeron. From this insight we estimate the jet quenching parameter in the hadron medium (largely a pion gas) at the end of the collision, which is naturally small and increases with temperature in line with the gas density and compare it to the jet quenching parameter obtained within the quark-gluon plasma (QGP) phase in widely known perturbative approximations. The physics in the quark-gluon plasma/liquid phase is less obvious, and here we revisit a couple of simple estimates that suggest indeed that the pomeron-mediated interactions are very relevant and should be included in analysis of the jet quenching parameter. Finally, since the occasional hard collisions produce features characteristic of a Lèvy flight in the q⊥2 plane perpendicular to the jet axis, we suggest one- and two-particle q⊥ correlations as interesting experimental probes sensitive to the nature (softness versus hardness) of the interactions of a jet inside the QGP.

  15. A polyvinylsiloxane denture soft lining material.

    PubMed

    McCabe, J F

    1998-01-01

    A new denture soft lining material based on a polyvinylsiloxane system, similar to that used in addition-curing silicone impression materials, has recently been developed. The purpose of the work reported here was to compare certain key properties of the new material with those of other commercially available materials. Setting characteristics, resistance to penetration, elastic properties, water absorption, peel strength and contact angle with water were determined for five materials including the new product. In addition, the change in properties following water storage were determined. In many respects the properties of the new material were noted to be similar to those of a heat-cured silicone product. It is initially elastic and of "medium" softness as defined by ISO 10139-2. It was the only product which did not lose weight on storage in water and over 90 days of storage it gave only a small change in compliance as measured by surface penetration. Bond strength of the new material to an acrylic denture base appears only moderate. However, failure was cohesive within the soft material with no peeling, suggesting that peeling is unlikely to occur in practice. The affinity between the surface of the material and water, as determined by contact angle, is significantly better than for other silicone products. The properties of the polyvinylsiloxane denture soft lining material are in many respects similar to those of other silicone soft lining materials. However, the efficacy of the adhesive which prevents peeling combined with a convenient packaging, proportioning and mixing system suggests that the material may offer some advantages which warrant its clinical evaluation.

    Soft computing is a collection of methodologies that aim to exploit the tolerance for imprecision and uncertainty to achieve tractability, robustness, and low solution cost. Its principal constituents are fuzzy logic, neuro-computing, and probabilistic reasoning. Soft computing is likely to play an increasingly important role in many application areas, including software engineering. The role model for soft computing is the human mind.

    We measure the production cross section of t{bar t} events in p{bar p} collisions at {radical}s = 1.96 TeV. The data was collected by the CDF experiment in Run 2 of the Tevatron accelerator at the Fermi National Accelerator Laboratory between 2002 and 2007. 1.7 fb{sup -1} of data was recorded during this time period. We reconstruct t{bar t} events in the lepton+jets channel, whereby one W boson - resulting from the decay of the top quark pairs - decays leptonically and the other hadronically. The dominant background to this process is the production of W bosons in association with multiple jets. To distinguish t{bar t} from background, we identify soft electrons from the semileptonic decay of heavy flavor jets produced in t{bar t} events. We measure a cross section of {sigma}{sub p{bar p}} = 7.8 {+-} 2.4(stat) {+-} 1.6(syst) {+-} 0.5(lumi).

  1. Identified light-flavour particle production measured with ALICE at the LHC as a probe of soft QCD and hot hadronic matter

    NASA Astrophysics Data System (ADS)

    Guerzoni, Barbara; ALICE Collaboration

    2015-05-01

    ALICE is a general-purpose heavy-ion experiment able to identify particles over a wide momentum range thanks to excellent vertexing and tracking performance, low material budget and different Particle IDentification (PID) techniques. In this paper the measurement of the production of identified light flavour particles in pp, p-Pb and Pb-Pb collisions is reported. It is of fundamental importance to study the particle production mechanisms playing a role in the different momentum ranges and probe the hot medium formed in heavy-ion collisions. Information on the effects of the medium produced in Pb-Pb collisions on particle production can be obtained comparing the particle ratios in pp and Pb-Pb events and studying the nuclear modification factor (RAA). The transverse momentum (pT) integrated yields and ratios are then discussed in terms of thermal models to extract the properties of the medium produced in Pb-Pb collisions at the chemical freeze-out.

  2. Biological Soft Robotics.

    Feinberg, Adam W

    2015-12-01

    In nature, nanometer-scale molecular motors are used to generate force within cells for diverse processes from transcription and transport to muscle contraction. This adaptability and scalability across wide temporal, spatial, and force regimes have spurred the development of biological soft robotic systems that seek to mimic and extend these capabilities. This review describes how molecular motors are hierarchically organized into larger-scale structures in order to provide a basic understanding of how these systems work in nature and the complexity and functionality we hope to replicate in biological soft robotics. These span the subcellular scale to macroscale, and this article focuses on the integration of biological components with synthetic materials, coupled with bioinspired robotic design. Key examples include nanoscale molecular motor-powered actuators, microscale bacteria-controlled devices, and macroscale muscle-powered robots that grasp, walk, and swim. Finally, the current challenges and future opportunities in the field are addressed. PMID:26643022

  3. Soft-sediment mullions

    NASA Astrophysics Data System (ADS)

    Ortner, Hugo

    2015-04-01

    In this contribution I describe the appearance, formation and significance of soft-sediment mullions. I use several examples from synorogenic turbidites of the Alps and the Pyrenees to show their appearance in the field. Soft-sediment mullions are elongate, slightly irregular bulges at the base of coarse-grained clastic beds (sand to conglomerate), separated by narrow, elongate flames of fine-grained material (mud) protruding into the coarse-grained bed. Various processes may lead to the formation of such structures: (1) longitudinal furrows parallel to the sediment transport direction may form by spiral motion in flow rolls during sediment transport (Dzulinski, 1966; Dzulinski & Simpson, 1966). (2) Loading combined with downslope movement can produce elongate structures parallelling the dowslope direction (Anketell et al., 1970). (3) Soft-sediment mullions are oriented perpendicular or oblique to the downslope direction, and show evidence of bedding-parallel shortening. Thus, they resemble cuspate-lobate folds or mullions, which are well-known in ductile structural geology (e.g. Urai et al., 2001). Soft-sediment mullions have been observed in two cases: Either bedding-parallel shortening can be achieved by slump processes, or by active tectonic shortening. Slumping is characterized by an alternation of stretching and shortening (e.g. Ortner, 2007; Alsop & Marco 2014), and therefore mullions do overprint or are overprinted by normal faults. In active depositional systems that are subject to tectonic shortening growth strata will form, but sediments already deposited will be shortened during lithification. In some cases, the formation of soft-sediment mullions predates folding, but the most widespread expression of syn-lithification shortening seems to be soft-sediment mullions, that form in the inner arcs of fold hinges. In the examples documented so far, the size of soft-sediment mullions is dependent on the grain-size of the coarse-grained layer, in which the mullions form. In coarse conglomerates, meter-scale mullions were observed, in sandstones centimeter-scale mullions. There does not seem to exist a relationship to the rate of shortening, as the size of mullions is independent of their position in larger scale folds, or in slump complexes or tectonic folds.

    The surgical approach to reptiles can be challenging. Reptiles have unique physiologic, anatomic, and pathologic differences. This may result in frustrating surgical experiences. However, recent investigations provided novel, less invasive, surgical techniques. The purpose of this review was to describe the technical aspects behind soft tissue surgical techniques that have been used in reptiles, so as to provide a general guideline for veterinarians working with reptiles.

  7. Hypoelastic Soft Tissues

    PubMed Central

    Freed, Alan D.; Einstein, Daniel R.; Sacks, Michael S.

    2010-01-01

    In Part I, a novel hypoelastic framework for soft-tissues was presented. One of the hallmarks of this new theory is that the well-known exponential behavior of soft-tissues arises consistently and spontaneously from the integration of a rate based formulation. In Part II, we examine the application of this framework to the problem of biaxial kinematics, which are common in experimental soft-tissue characterization. We confine our attention to an isotropic formulation in order to highlight the distinction between non-linearity and anisotropy. In order to provide a sound foundation for the membrane extension of our earlier hypoelastic framework, the kinematics and kinetics of in-plane biaxial extension are revisited, and some enhancements are provided. Specifically, the conventional stress-to-traction mapping for this boundary value problem is shown to violate the conservation of angular momentum. In response, we provide a corrected mapping. In addition, a novel means for applying loads to in-plane biaxial experiments is proposed. An isotropic, isochoric, hypoelastic, constitutive model is applied to an in-plane biaxial experiment done on glutaraldehyde treated bovine pericardium. The experiment is comprised of eight protocols that radially probe the biaxial plane. Considering its simplicity (two adjustable parameters) the model does a reasonably good job of describing the non-linear normal responses observed in these experimental data, which are more prevalent than are the anisotropic responses exhibited by this tissue.

  8. Soft hub for bearingless rotors

    Dixon, Peter G. C.

    1991-01-01

    Soft hub concepts which allow the direct replacement of articulated rotor systems by bearingless types without any change in controllability or need for reinforcement to the drive shaft and/or transmission/fuselage attachments of the helicopter were studied. Two concepts were analyzed and confirmed for functional and structural feasibility against a design criteria and specifications established for this effort. Both systems are gimballed about a thrust carrying universal elastomeric bearing. One concept includes a set of composite flexures for drive torque transmittal from the shaft to the rotor, and another set (which is changeable) to impart hub tilting stiffness to the rotor system as required to meet the helicopter application. The second concept uses a composite bellows flexure to drive the rotor and to augment the hub stiffness provided by the elastomeric bearing. Each concept was assessed for weight, drag, ROM cost, and number of parts and compared with the production BO-105 hub.

  10. Soft Magnetic Materials for Improved Energy Performance

    NASA Astrophysics Data System (ADS)

    Willard, Matthew

    2012-02-01

    A main focus of sustainable energy research has been development of renewable energy technologies (e.g. from wind, solar, hydro, geothermal, etc.) to decrease our dependence on non-renewable energy resources (e.g. fossil fuels). By focusing on renewable energy sources now, we hope to provide enough energy resources for future generations. In parallel with this focus, it is essential to develop technologies that improve the efficiency of energy production, distribution, and consumption, to get the most from these renewable resources. Soft magnetic materials play a central role in power generation, conditioning, and conversion technologies and therefore promoting improvements in the efficiency of these materials is essential for our future energy needs. The losses generated by the magnetic core materials by hysteretic, acoustic, and/or eddy currents have a great impact on efficiency. A survey of soft magnetic materials for energy applications will be discussed with a focus on improvement in performance using novel soft magnetic materials designed for these power applications. A group of premiere soft magnetic materials -- nanocrystalline soft magnetic alloys -- will be highlighted for their potential in addressing energy efficiency. These materials are made up of nanocrystalline magnetic transition metal-rich grains embedded within an intergranular amorphous matrix, obtained by partial devitrification of melt-spun amorphous ribbons. The nanoscale grain size results in a desirable combination of large saturation induction, low coercivity, and moderate resistivity unobtainable in conventional soft magnetic alloys. The random distribution of these fine grains causes a reduction in the net magnetocrystalline anisotropy, contributing to the excellent magnetic properties. Recently developed (Fe,Co,Ni)88Zr7B4Cu1 alloys will be discussed with a focus on the microstructure/magnetic property relationship and their effects on the energy efficiency of these materials for AC applications.

  11. Structure and Secondary Production of a Soft Bottom Macrobenthic Community in a Brackish Lagoon (Sacca di Goro, north-eastern Italy)

    NASA Astrophysics Data System (ADS)

    Mistri, M.; Rossi, R.; Fano, E. A.

    2001-05-01

    The composition and distribution of the macrobenthic community in a lagoon in the Po River delta was investigated by taking monthly samples at three sites during 1994. A total of 38 macroinvertebrate taxa, representing five phyla, were identified. Gastropods, amphipods, and chironomid larvae dominated the macrofauna in term of abundance, while in terms of biomass bivalves were the dominant taxon. Monthly total invertebrate abundance showed considerable fluctuations, depending on the season and on the presence of the red macroalgae Gracilaria verrucosa. In the central area of the lagoon, a significant relationship was demonstrated between macrobenthic community parameters and amount of macroalgal cover. Taking the most important species, i.e. those that contributed most to similarity within sites, only Cerastoderma glaucum was found to be negatively related to the amount of macroalgal biomass. Mean annual secondary production varied between 50 and 75 g AFDW m -2yr -1depending on the site, yielding P/B ratios between 1·02 and 1·08. Confinement and moderate disturbance due to the presence of algal cover are hypothesized to determine structure, composition, and production of the macrobenthic community in the Sacca di Goro.

    A brief history is given of approaches that aim at achieving a connectedness of the content of organic chemistry courses to real world issues. Recently, such approaches have relied more and more on online media resources, the tools of the Internet and the World Wide Web. We propose a six-level taxonomy of ‘authentic news media-based learning activities’ to provide a conceptual framework for the description and discussion of such approaches. The Chemistry Is in the News project was designed to allow students to draw explicit connections between the course content and real world issues in ways that engage the students in a full range of cognitive skills. The activities consisted in the study, creation, and peer review of news portfolios by student collaborative groups. A news portfolio consists of an authentic news article taken from the popular press with interpretive comments and questions.

    2004-12-01

    Teachable Moments in the News (www.challenger.org/tmn/) is an online resource developed at Challenger Center for Space Science Education that takes recent news stories related to Solar System science and places them in a context relevant to the grades K-12 science curriculum. Using stories such as the launch of the MESSENGER spacecraft to Mercury, Teachable Moments in the News is meant to provide a seamless pathway from the news desk to the classroom. For each news item, an overview of the story is provided, along with high-quality inquiry-based, standards-driven lessons and links to more in-depth articles. Teachable Moments in the News is also a great tool for scientists who wish to stay informed of the recent events in Solar System exploration. The archived back issues of the quarterly published Web digest allow for a quick refresher on the most important news stories over the past several months. The very accessible nature of the stories makes the resource valuable for college students, and even the general public, as a means to keep up-to-date about current developments in planetary astronomy. Furthermore, college and university teachers can easily adapt many of the lessons to fit into the curriculum of an undergraduate astronomy course. During the poster session, we welcome suggestions from the scientific community on ways to enhance the usefulness of Teachable Moments in the News. For example, researchers could form partnerships with Teachable Moments in the News to provide news stories on their current research to be featured on the Web site. We invite researchers interested in this education and public outreach tool to visit the poster and provide suggestions on how to make the resource work as effectively as possible.

    Soft skills and hard skills are essential in the practice of dentistry. While hard skills deal with technical proficiency, soft skills relate to a personal values and interpersonal skills that determine a person's ability to fit in a particular situation. These skills contribute to the success of organisations that deal face-to-face with clients. Effective soft skills benefit the dental practice. However, the teaching of soft skills remains a challenge to dental schools. This paper discusses the different soft skills, how they are taught and assessed and the issues that need to be addressed in their teaching and assessment.

  4. Physician-patient communication: breaking bad news.

    PubMed

    Fields, Scott A; Johnson, W Michael

    2012-01-01

    Physicians often struggle with how to manage the task of breaking bad news with patients. Moreover, the arduous nature of the task can contribute to physician detachment from the patient or an avoidance of breaking the news in a timely manner. A plan of action can only improve physician confidence in breaking bad news, and also make the task more manageable. Over a decade ago, Rabow and McPhee offered a strategy; the ABCDE plan, which provided a patient centered framework from which to deliver troubling news to patients and families. At the heart of this plan was the creation of a safe environment, the demonstration of timely communication skills, and the display of empathy on the physician's part. Careful consideration of the doctor's own reactions to death and dying also played an important role. A close review of the five tenets of this plan indicates the relevance of Rabow and McPhee's strategy today. The patient base in our nation and state continues to be older, on average, and physicians are faced with numerous patients who have terminal illness. A constructive plan with specific ideas for breaking bad news can help physicians effectively navigate this difficult task. PMID:22655433

  5. Measuring the Interestingness of News Articles

    SciTech Connect

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

  6. Deployable Soft Composite Structures.

    PubMed

    Wang, Wei; Rodrigue, Hugo; Ahn, Sung-Hoon

    2016-01-01

    Deployable structure composed of smart materials based actuators can reconcile its inherently conflicting requirements of low mass, good shape adaptability, and high load-bearing capability. This work describes the fabrication of deployable structures using smart soft composite actuators combining a soft matrix with variable stiffness properties and hinge-like movement through a rigid skeleton. The hinge actuator has the advantage of being simple to fabricate, inexpensive, lightweight and simple to actuate. This basic actuator can then be used to form modules capable of different types of deformations, which can then be assembled into deployable structures. The design of deployable structures is based on three principles: design of basic hinge actuators, assembly of modules and assembly of modules into large-scale deployable structures. Various deployable structures such as a segmented triangular mast, a planar structure comprised of single-loop hexagonal modules and a ring structure comprised of single-loop quadrilateral modules were designed and fabricated to verify this approach. Finally, a prototype for a deployable mirror was developed by attaching a foldable reflective membrane to the designed ring structure and its functionality was tested by using it to reflect sunlight onto to a small-scale solar panel.

    2011-06-01

    Recommender systems represent an important tool for news distribution on the Internet. In this work we modify a recently proposed social recommendation model in order to deal with no explicit ratings of users on news. The model consists of a network of users which continually adapts in order to achieve an efficient news traffic. To optimize the network's topology we propose different stochastic algorithms that are scalable with respect to the network's size. Agent-based simulations reveal the features and the performance of these algorithms. To overcome the resultant drawbacks of each method we introduce two improved algorithms and show that they can optimize the network's topology almost as fast and effectively as other not-scalable methods that make use of much more information.

    2000-01-01

    Reporting of astronomical discoveries and events in the news media continues to expand to satisfy a seemingly voracious public interest. New telescopes, instruments, and facilities both up in space and on the ground, provide unique opportunities for media outreach on what scientists are accomplishing. And, new media such as website news providers, high-definition television, and video news walls help to fuel the growing activity. Ever since Tycho Brahe operated his own printing press, astronomers have striven to document their accomplishments for the wider world. In recent years, astronomers' media outreach has been successful in reaching the mass television audience through successful efforts at animation and scientific visualization, and through dramatic images acquired by some facilities, such as the solar physics satellites and ground observatories.

  18. Softness perceptive texture method

    NASA Astrophysics Data System (ADS)

    Kobayashi, Yuichi; Suzuki, Masami; Ohya, Jun

    2004-06-01

    We have been studying about people's visual impression and image features for texture images in order to clarify the human subjective interpretation mechanism for images[1]. In corresponding image features of human impressions for the images, we found that the impressions for material were bottle-necked. We have studied a new analysis method which gives the impression for material from texture images. Especially, we mainly focused on the properties of visual targets which people can feel tactile sense. In this paper, we propose a new texture analysis method which is based on frequency analysis with 3D texture which is designed for photorealistic rendering. We found that our new method can estimate not only the surface roughness but also the surface softness.

  19. Soft Systems Methodology

    NASA Astrophysics Data System (ADS)

    Checkland, Peter; Poulter, John

    Soft systems methodology (SSM) is an approach for tackling problematical, messy situations of all kinds. It is an action-oriented process of inquiry into problematic situations in which users learn their way from finding out about the situation, to taking action to improve it. The learning emerges via an organised process in which the situation is explored using a set of models of purposeful action (each built to encapsulate a single worldview) as intellectual devices, or tools, to inform and structure discussion about a situation and how it might be improved. This paper, written by the original developer Peter Checkland and practitioner John Poulter, gives a clear and concise account of the approach that covers SSM's specific techniques, the learning cycle process of the methodology and the craft skills which practitioners develop. This concise but theoretically robust account nevertheless includes the fundamental concepts, techniques, core tenets described through a wide range of settings.

  20. [Deep soft tissue infections].

    Chargui, M; Uçkay, I; Suvà, D; Christofilopoulos, P; Lomessy, A; Pittet, D

    2014-04-23

    The clinical presentations of deep soft tissue infections can, initially, mimicry superficial skin infections such as erysipelas. However, a rapidly deteriorating health status, the spreading of the lesions and the lack of clear visual limitation of the infection on the skin are hallmarks of a more severe underlying infection, which may endanger patients' life. An immediate adequate multidisciplinary approach to therapy within a few hours is mandatory. The first step is surgical exploration with debridement of all infected tissues, accompanied by antibiotic therapy and additional supportive measures. Despite progress in the understanding of the physiopathology, the delay between suspicion of diagnosis and surgical exploration remains critical. Because of the low incidence of such severe infections, only multicenter studies might reveal deeper insights of optimal therapeutic strategies in the future and for possible improved patients' survival.

  4. The soft keratoprosthesis.

    PubMed Central

    Caldwell, D R

    1997-01-01

    PURPOSE: The purpose of this work was to develop a keratoprosthesis which utilizes a biocolonizable skirt attached to a soft, elastomeric optic for world-wide application. METHODS: Over a period of 20 years, using in vivo animal implantation studies, a series of experiments was conducted testing materials for biocompatibility and durability which resulted in the development of an improved design. A new surgical technique was developed, using porous, biocolonizable haptics embedded within the sclera and combined with the established techniques of resection of Descemet's membrane and a conjunctival flap. RESULTS: Animal implantation studies indicated that 6 haptics, equidistantly placed, was the optimal shape. Two clinical trials resulted in the selection of an aliphatic polyether-based urethane for the optic and 60 mu pore polytetrafluoroethylene for the porous ingrowth material. Heated, pressurized injection moulding proved to be the optimal bonding method between the skirt and the optic. Sclerally embedded haptics achieved excellent integration with the tissue. CONCLUSIONS: This keratoprosthesis is a significant improvement over previous models with a rigid optic in that: 1. The porous ingrowth haptic is sclerally anchored, preventing extrusion. 2. It has a soft elastomeric optic which more successfully defuses the shearing forces of the keratoprosthesis/tissue interface secondary to blinking. 3. The optic is less massive and of greater circumference at the optic/tissue interface, thereby imparting less energy per area with a given movement. 4. The optic does not project posteriorly thereby decreasing anterior chamber irritation and reducing the possibility of glaucoma, uveitis, endophthalmitis, and retinal detachment. 5. This keratoprosthesis allows a normal field of view for the patient and an effective funduscopic view for the surgeon. 6. The large optical diameter eliminates problems with decentralization of the image. 7. It has a significantly better cosmetic appearance.

  5. New double soft emission theorems

    Cachazo, Freddy; He, Song; Yuan, Ellis Ye

    2015-09-01

    We study the behavior of the tree-level S-matrix of a variety of theories as two particles become soft. By analogy with the recently found subleading soft theorems for gravitons and gluons, we explore subleading terms in double soft emissions. We first consider double soft scalar emissions and find subleading terms that are controlled by the angular momentum operator acting on hard particles. The order of the subleading theorems depends on the presence or not of color structures. Next we obtain a compact formula for the leading term in a double soft photon emission. The theories studied are a special Galileon, Dirac-Born-Infeld, Einstein-Maxwell-Scalar, nonlinear sigma model and Yang-Mills-Scalar. We use the recently found Cachazo-He-Yuan representation of these theories in order to give a simple proof of the leading order part of all these theorems.

  6. Optimization of magnetic stirring assisted dispersive liquid-liquid microextraction of rhodamine B and rhodamine 6G by response surface methodology: Application in water samples, soft drink, and cosmetic products.

    2015-07-01

    An exact, rapid and efficient method for the extraction of rhodamine B (RB) and rhodamine 6G (RG) as well as their determination in three different matrices was developed using magnetic stirring assisted dispersive liquid-liquid microextraction (MSA-DLLME) and HPLC-Vis. 1-Octanol and acetone were selected as the extraction and dispersing solvents, respectively. The potentially variables were the volume of extraction and disperser solvents, pH of sample solution, salt effect, temperature, stirring rate and vortex time in the optimization process. A methodology based on fractional factorial design (2(7)(-2)) was carried out to choose the significant variables for the optimization. Then, the significant factors (extraction solvent volume, pH of sample solution, temperature, stirring rate) were optimized using a central composite design (CCD). A quadratic model between dependent and independent variables was built. Under the optimum conditions (extraction solvent volume=1050L, pH=2, temperature=35C and stirring rate=1500rpm), the calibration curves showed high levels of linearity (R(2)=0.9999) for RB and RG in the ranges of 5-1000ngmL(-1) and 7.5-1000ngmL(-1), respectively. The obtained extraction recoveries for 100ngmL(-1) of RB and RG standard solutions were 100% and 97%, and preconcentration factors were 48 and 46, respectively. While the limit of detection was 1.15ngmL(-1) for RB, it was 1.23ngmL(-1) for RG. Finally, the MSA-DLLME method was successfully applied for preconcentration and trace determination of RB and RG in different matrices of environmental waters, soft drink and cosmetic products.

    Graphical abstract: - Highlights: • Exchange-spring behaviour of soft and hard ferrites was studied. • XRD patterns indicated soft and hard ferrites as fcc and hcp structure. • Hysteresis loops indicate wide difference in coercivity of soft and hard phases. • Nanocomposites produced convex hysteresis loop characteristic of single-phase. - Abstract: The paper reports exchange-spring soft and hard ferrite nanocomposites synthesized by chemical co-precipitation with or without the application of ultrasonic vibration. The composites contained BaFe{sub 12}O{sub 19} as the hard phase and CoFe{sub 2}O{sub 4}/MgFe{sub 2}O{sub 4} as the soft phase. X-ray diffraction patterns of the samples in the optimum calcined condition indicated the presence of soft ferrites as face-centred cubic (fcc) and hard ferrites as hexagonal close packed (hcp) structure respectively. Temperature dependence of magnetization in the range of 20–700 °C demonstrated distinct presence of soft and hard ferrites as magnetic phases which are characterized by wide difference in magnetic anisotropy and coercivity. Exchange-spring mechanism led these nanocomposite systems to exchange-coupled, which ultimately produced convex hysteresis loops characteristic of a single-phase permanent magnet. Fairly high value of coercivity and maximum energy product were observed for the samples in the optimum calcined conditions with a maximum applied field of 1600 kA/m (2 T)

  12. A new temporary soft lining material.

    PubMed

    Jepson, N J; McCabe, J F; Basker, R M

    1995-04-01

    The viscoelastic properties of a new light-activated temporary denture soft lining material have been monitored in vitro using a force/distance probe. Its baseline behaviour was characteristic of an elastic material and its compliance considerably less than that of both a short-term and a long-term soft lining material which were used as controls. Sample thickness had no appreciable effect on this compliance. These results suggest that the new product is likely to be perceived as being significantly harder by a patient. Twenty-four weeks' immersion in distilled water had no significant effect on either the compliance or elasticity of the test material and would suggest an improved durability when compared to other conventional short-term resilient denture lining materials, albeit at the expense of compliance.

    Roasted groundnut seeds, amaranth and dates pulp formed the center filling which was coated with sugar, breadings, desiccated coconut and roasted Bengalgram flour (BGF) to get 4 coated snacks. Physicochemical characteristics, microbiological profile, sorption behaviour and sensory quality of 4 coated snacks were determined. Centre filling to coating ratio of the products were in the range of 3:2-7:1, the product having BGF coating had the thinnest coating. Center filling had soft texture and the moisture content was 10.2-16.2% coating had lower moisture content (4.4-8.6%) except for Bengal gram coating, which had 11.1% moisture. Sugar coated snack has lowest fat (11.6%) and protein (7.2%) contents. Desiccated coconut coated snack has highest fat (25.4%) and Bengal gram flour coated snack had highest protein content (15.4%). Sorption studies showed that the coated snack had critical moisture content of 11.2-13.5%. The products were moisture sensitive and hence require packaging in films having higher moisture barrier property. In freshly prepared snacks coliforms, yeast and mold were absent. Mesophillic aerobes count did not show significant change during 90days of storage at 27C and 37C. Sensory analysis showed that products had a unique texture due to combined effect of fairly hard coating and soft center. Flavour and overall quality of all the products were rated as very good.

  19. A fuzzy ontology and its application to news summarization.

    2005-10-01

    In this paper, a fuzzy ontology and its application to news summarization are presented. The fuzzy ontology with fuzzy concepts is an extension of the domain ontology with crisp concepts. It is more suitable to describe the domain knowledge than domain ontology for solving the uncertainty reasoning problems. First, the domain ontology with various events of news is predefined by domain experts. The document preprocessing mechanism will generate the meaningful terms based on the news corpus and the Chinese news dictionary defined by the domain expert. Then, the meaningful terms will be classified according to the events of the news by the term classifier. The fuzzy inference mechanism will generate the membership degrees for each fuzzy concept of the fuzzy ontology. Every fuzzy concept has a set of membership degrees associated with various events of the domain ontology. In addition, a news agent based on the fuzzy ontology is also developed for news summarization. The news agent contains five modules, including a retrieval agent, a document preprocessing mechanism, a sentence path extractor, a sentence generator, and a sentence filter to perform news summarization. Furthermore, we construct an experimental website to test the proposed approach. The experimental results show that the news agent based on the fuzzy ontology can effectively operate for news summarization. PMID:16240764

  20. Soft Decision Analyzer

    2013-01-01

    The Soft Decision Analyzer (SDA) is an instrument that combines hardware, firmware, and software to perform realtime closed-loop end-to-end statistical analysis of single- or dual- channel serial digital RF communications systems operating in very low signal-to-noise conditions. As an innovation, the unique SDA capabilities allow it to perform analysis of situations where the receiving communication system slips bits due to low signal-to-noise conditions or experiences constellation rotations resulting in channel polarity in versions or channel assignment swaps. SDA s closed-loop detection allows it to instrument a live system and correlate observations with frame, codeword, and packet losses, as well as Quality of Service (QoS) and Quality of Experience (QoE) events. The SDA s abilities are not confined to performing analysis in low signal-to-noise conditions. Its analysis provides in-depth insight of a communication system s receiver performance in a variety of operating conditions. The SDA incorporates two techniques for identifying slips. The first is an examination of content of the received data stream s relation to the transmitted data content and the second is a direct examination of the receiver s recovered clock signals relative to a reference. Both techniques provide benefits in different ways and allow the communication engineer evaluating test results increased confidence and understanding of receiver performance. Direct examination of data contents is performed by two different data techniques, power correlation or a modified Massey correlation, and can be applied to soft decision data widths 1 to 12 bits wide over a correlation depth ranging from 16 to 512 samples. The SDA detects receiver bit slips within a 4 bits window and can handle systems with up to four quadrants (QPSK, SQPSK, and BPSK systems). The SDA continuously monitors correlation results to characterize slips and quadrant change and is capable of performing analysis even when the receiver under test is subjected to conditions where its performance degrades to high error rates (30 percent or beyond). The design incorporates a number of features, such as watchdog triggers that permit the SDA system to recover from large receiver upsets automatically and continue accumulating performance analysis unaided by operator intervention. This accommodates tests that can last in the order of days in order to gain statistical confidence in results and is also useful for capturing snapshots of rare events.

    Soft drinks consumption is still a controversial issue for public health and public policy. Over the years, numerous studies have been conducted into the possible links between soft drink intake and medical problems, the results of which, however, remain highly contested. Nevertheless, as a result, increasing emphasis is being placed on the health properties of soft drinks, by both the industry and the consumers, for example, in the expanding area of functional drinks. Extensive legislation has been put in place to ensure that soft drinks manufacturers conform to established national and international standards. Consumers trust that the soft drinks they buy are safe and their quality is guaranteed. They also expect to be provided with information that can help them to make informed decisions about the purchase of products and that the information on product labels is not false or misleading. This paper provides a broad overview of available scientific knowledge and cites numerous studies on various aspects of soft drinks and their implications for health safety. Particular attention is given to ingredients, including artificial flavorings, colorings, and preservatives and to the lesser known risks of microbiological and chemical contamination during processing and storage.

    Motivated by recent financial crises, significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. Much less has been said regarding the influence of financial news on financial markets. We propose a novel measure of collective behaviour based on financial news on the Web, the News Cohesiveness Index (NCI), and we demonstrate that the index can be used as a financial market volatility indicator. We evaluate the NCI using financial documents from large Web news sources on a daily basis from October 2011 to July 2013 and analyse the interplay between financial markets and finance-related news. We hypothesise that strong cohesion in financial news reflects movements in the financial markets. Our results indicate that cohesiveness in financial news is highly correlated with and driven by volatility in financial markets.

    Among other focus areas, interventions designed to improve children's diets need to address key factors contributing to children's consumption of sugar-sweetened beverages. The present study employed structural equation modelling to investigate the relationship between a broad range of predictor variables and the frequency with which Australian children consume soft drinks. In total, 1302 parents of children aged 8 to 14 years responded to an online survey about their children's food consumption behaviours. Soft drink consumption frequency was primarily influenced by parents' attitudes to soft drinks, children's pestering behaviours, and perceived social norms relating to children's consumption of these products. Importantly, pestering and social norms had significant direct effects on consumption frequency in addition to indirect effects via their impact on parents' attitudes to soft drink. PMID:25953597

  6. A website for astronomical news in Spanish

    NASA Astrophysics Data System (ADS)

    Ortiz-Gil, A.

    2008-06-01

    Noticias del Cosmos is a collection of web pages within the Astronomical Observatory of the University of Valencia's website where we publish short daily summaries of astronomical press releases. Most, if not all of, the releases are originally written in English, and often Spanish readers may find them difficult to understand because not many people are familiar with the scientific language employed in these releases. Noticias del Cosmos has two principal aims. First, we want to communicate the latest astronomical news on a daily basis to a wide Spanish-speaking public who would otherwise not be able to read them because of the language barrier. Second, daily news can be used as a tool to introduce the astronomical topics of the school curriculum in a more immediate and relevant way. Most of the students at school have not yet reached a good enough level in their knowledge of English to fully understand a press release, and Noticias del Cosmos offers them and their teachers this news in their mother tongue. During the regular programme of school visits at the Observatory we use the news as a means of showing that there is still a lot to be discovered. So far the visits to the website have been growing steadily. Between June 2003 and June 2007 we had more than 30,000 visits (excluding 2006). More than 50% of the visits come from Spain, followed by visitors from South and Central America. The feedback we have received from teachers so far has been very positive, showing the usefulness of news items in the classroom when teaching astronomy.

    Magnetic resonance imaging is the mainstay of diagnostic imaging for soft tissue masses, but plain film, ultrasound, and computed tomography all have roles. A subset of lesions has specific imaging features that enable a confident radiological diagnosis with appropriate clinical correlation. Many soft tissue masses have nonspecific appearances and should be considered for biopsy in a specialist center. When a biopsy is required for definitive diagnosis, careful multidisciplinary planning is essential to avoid contamination of unaffected tissue, leading to recurrence and unnecessary amputations. This article discusses radiological diagnosis, biopsy, and management of the soft tissue mass. PMID:25246054

  8. The soft genome

    2014-01-01

    Caenorhabditis elegans (C. elegans) nematodes transmit small RNAs across generations, a process that enables transgenerational regulation of genes. In contrast to changes to the DNA sequence, transgenerational transmission of small RNA-mediated responses is reversible, and thus enables soft or flexible inheritance of acquired characteristics. Until very recently only introduction of foreign genetic material (viruses, transposons, transgenes) was shown to directly lead to inheritance of small RNAs. New discoveries however, demonstrate that starvation also triggers inheritance of endogenous small RNAs in C.elegans. Multiple generations of worms inherit starvation-responsive endogenous small RNAs, and starvation also results in heritable extension of the progeny's lifespan. In this Commentary paper we explore the intriguing possibility that large parts of the genome and many additional traits are similarly subjected to heritable small RNA-mediated regulation, and focus on the potential influence of transgenerational RNAi on the worm's physiology. While the universal relevance of this mechanism remains to be discovered, we will examine how the discoveries made in worms already challenge long held dogmas in genetics and evolution.

  9. Polymers and Soft Matter

    NASA Astrophysics Data System (ADS)

    Mahadevan, L.; Rutledge, Gregory C.

    Within the context of this Handbook, the combined areas ofpolymers and soft matter encompasses a vast range of complex materials, including both synthetic and natural polymers, many biological materials, and complex fluids such as colloids and viscoelastic media. What distinguishes these materials from most of those considered in other chapters of this Handbook is the macromolecular or supermolecular nature of the basic components of the material. In addition to the usual atomic level interactions responsible for chemically specific material behavior, as is found in all materials, these macromolecular and supermolecular objects exhibit topological features that lead to new, larger scale, collective nonlinear and nonequilibrium behaviors that are not seen in the constituents. As a consequence, these materials are typically characterized by a broad range of both length and time scales over which phenomena of both scientific and engineering interest can arise. In polymers, for instance, the organic nature of the molecules is responsible for both strong (intramolecular, covalent) and weak (intermolecular, van der Waals) interactions, as well as interactions of intermediate strength such as hydrogen bonds that are common in macromolecules of biological interest. In addition, however, the long chain nature of the molecule introduces a distinction between dynamics that occur along the chain or normal to it; one consequence of this is the observation of certain generic behaviors such as the "slithering snake" motion, or reptation, in polymer dynamics.

    2015-03-01

    Over the past a few years, we have developed Resonant Soft X-ray Scattering (RSoXS) and constructed the first dedicated resonant soft x-ray scattering beamline at the Advanced Light Source, LBNL. RSoXS combines soft x-ray spectroscopy with x-ray scattering thus offers statistical information for 3D chemical morphology over a large length scale range from nanometers to micrometers. Its unique chemical sensitivity, large accessible size scale, molecular bond orientation sensitivity with polarized x-rays and high coherence have shown great potential for chemical/morphological structure characterization for many classes of materials. Some recent development of in-situ soft x-ray scattering with in-vacuum sample environment will be discussed. In order to study sciences in naturally occurring conditions, we need to overcome the sample limitations set by the low penetration depth of soft x-rays and requirement of high vacuum. Adapting to the evolving environmental cell designs utilized increasingly in the Electron Microscopy community, customized designed liquid/gas environmental cells will enable soft x-ray scattering experiments on biological, electro-chemical, self-assembly, and hierarchical functional systems in both static and dynamic fashion. Recent RSoXS results on organic electronics, block copolymer thin films, and membrane structure will be presented.

    Wan, X. L.; Zhao, G. P.; Zhang, X. F.; Xia, J.; Zhang, X. C.; Morvan, F. J.

    2016-01-01

    The demagnetization process in hard/soft multilayer systems has been investigated systematically within a self-contained micromagnetic model when a deviation angle ? between the easy axis and the applied field exists. Hysteresis loops, spin distributions and energy products have been calculated with a finite hard layer thickness th. Both remanence and coercivity of the multilayer system decrease as ? increases, leading to a significant decrease of the maximum energy product. A 30 deviation of the easy axis could result in a drop of the maximum energy product by more than 60%, which offers a possible explanation on the large discrepancy between the experimental and theoretical energy products. The effect of the finite hard layer thickness on the demagnetization process is important, which can only be ignored when th is large enough.

  12. CW Coherent Soft X-Ray Laser

    NASA Astrophysics Data System (ADS)

    Niimura, Marvin

    2007-03-01

    CW Soft X-Ray Laser (CW-SXL) lasing at the ``water window" wavelengths (2.3 - 4.4 nm) is indispensable for CW structural (3D) study of biological polymers such as DNA and proteins. Unlike pulsed X-ray (laser) sources, CW-SXLs have a higher beam quality and do not rely on a high power pulsed laser. The electronic structure necessary for lasing soft X-ray lines is obtainable from a CW source of highly charged ions (HCIs). Soft X-ray emission due to the interaction of HCIs with neutral atoms is taking place in the quasar and cometary gases. Solar and (quasar's) stellar winds are naturally occurring CW sources of HCIs, for which a modern electron cyclotron ion source (ECRIS) can be used in laboratory. Appropriate X-ray cavity (equipped with Bragg reflector) and re-circulating neutral gas atoms can achieve the laser action at water window. Population inversion takes place naturally since the electron transfer from neutral gas atom to HCI is readily a Rydberg pumping, no TW pump laser, as used for pulsed X-ray source, is needed. My preliminary calculation has indicated that the achievable gain-length product gL =2.16 -6.48 with the laser output power P > 26.4 kW, exceeding the level of pulsed X-ray source.

  13. Efficient Tracking of News Topics Based on Chronological Semantic Structures in a Large-Scale News Video Archive

    NASA Astrophysics Data System (ADS)

    Ide, Ichiro; Kinoshita, Tomoyoshi; Takahashi, Tomokazu; Mo, Hiroshi; Katayama, Norio; Satoh, Shin'ichi; Murase, Hiroshi

    Recent advance in digital storage technology has enabled us to archive a large volume of video data. Thanks to this trend, we have archived more than 1,800 hours of video data from a daily Japanese news show in the last ten years. When considering the effective use of such a large news video archive, we assumed that analysis of its chronological and semantic structure becomes important. We also consider that providing the users with the development of news topics is more important to help their understanding of current affairs, rather than providing a list of relevant news stories as in most of the current news video retrieval systems. Therefore, in this paper, we propose a structuring method for a news video archive, together with an interface that visualizes the structure, so that users could track the development of news topics according to their interest, efficiently. The proposed news video structure, namely the topic thread structure, is obtained as a result of an analysis of the chronological and semantic relation between news stories. Meanwhile, the proposed interface, namely mediaWalker II, allows users to track the development of news topics along the topic thread structure, and at the same time watch the video footage corresponding to each news story. Analyses on the topic thread structures obtained by applying the proposed method to actual news video footages revealed interesting and comprehensible relations between news topics in the real world. At the same time, analyses on their size quantified the efficiency of tracking a user's topic-of-interest based on the proposed topic thread structure. We consider this as a first step towards facilitating video authoring by users based on existing contents in a large-scale news video archive.

    We present a soft, bearing-free artificial muscle motor that cannot only turn a shaft but also grip and reposition it through a flexible gear. The bearing-free operation provides a foundation for low complexity soft machines, with multiple degree-of-freedom actuation, that can act simultaneously as motors and manipulators. The mechanism also enables an artificial muscle controlled gear change. Future work will include self-sensing feedback for precision, multidegree-of-freedom operation.

    The recent discovery of the Higgs boson at the LHC attracts much attention to the precise calculation of its production cross section in quantum chromodynamics. In this work, we discuss the calculation of soft triple-emission phase space integral, which is an essential ingredient in the recently calculated soft-virtual corrections to Higgs boson production at next-to-next-to-next-to-leading order. The main techniques used this calculation are method of differential equation for Feynman integral, and integration of harmonic polylogarithms.

    2008-01-01

    Disorders of soft, peri-articular tissues are a common cause of musculoskeletal pain in elderly patients. Nevertheless, most physicians underestimate the role of soft tissue rheumatism in the pathomechanism of the pain. The impairments of soft tissue can not be diagnosed by X-rays examinations, whereas degenerative lesions of joints are easy diagnosed using this method even despite of their uncertain role in producing the symptoms. The incidence of pain syndromes originated from soft tissues differ regarding to the age of patients. In young subjects the incidence of all of them is generally low. Syndromes provoked by overloading during work: repetitive strain syndrome, canal tunnel syndrome, tennis elbow, golfers elbow, shoulder tendon coin disorders and myofascial pain syndrome are common in middle-aged patients. The morbidity of fibromialgia syndrome is also lower in old people probably as the result of diminished numbers and degenerative changes in nociceptive fibers. The syndromes prevailing in elderly patients include trochanteric syndrome and the pain syndromes provoked by muscle spasm depended on posture abnormalities. In the soft tissue pain syndrome prevention adapted to old age kinesitherapy and avoiding muscle overloading are recommended. Soft tissue pain syndromes are usually treated with non steroidal anti inflammatory drugs. In local pain syndromes better results can be obtained by local treatment. Local injections of glikocorticosteroids are usually very effective and safe. PMID:19562972

  17. Dissecting soft radiation with factorization.

    An essential part of high-energy hadronic collisions is the soft hadronic activity that underlies the primary hard interaction. It includes soft radiation from the primary hard partons, secondary multiple parton interactions (MPI), and factorization-violating effects. The invariant mass spectrum of the leading jet in Z+jet and H+jet events is directly sensitive to these effects, and we use a QCD factorization theorem to predict its dependence on the jet radius R, jet p_{T}, jet rapidity, and partonic process for both the perturbative and nonperturbative components of primary soft radiation. We prove that the nonperturbative contributions involve only odd powers of R, and the linear R term is universal for quark and gluon jets. The hadronization model in Pythia8 agrees well with these properties. The perturbative soft initial state radiation (ISR) has a contribution that depends on the jet area in the same way as the underlying event, but this degeneracy is broken by dependence on the jet p_{T}. The size of this soft ISR contribution is proportional to the color state of the initial partons, yielding the same positive contribution for gg→Hg and gq→Zq, but a negative interference contribution for qq[over ¯]→Zg. Hence, measuring these dependencies allows one to separate hadronization, soft ISR, and MPI contributions in the data. PMID:25793802

  20. Incurable Adler relation for soft neutrino interactions

    The Adler relation (AR), which bridges soft interactions of neutrinos and pions, might look as a manifestation of pion dominance. However neutrino cannot fluctuate to a pion because of lepton current conservation, instead it interacts via much heavier hadronic components. This fact leads to nontrivial relations between interaction amplitudes of different hadronic species, in particular, it links diagonal and off-diagonal diffractive interactions of pions. Absorptive corrections break these relations making the AR impossible to hold universally, i.e. for any target and at any energy. We predict a dramatic breakdown of the AR for coherent neutrino-production of pions on nuclei at all energies.

  1. Gravitational memory, BMS supertranslations and soft theorems

    2016-01-01

    The transit of a gravitating radiation pulse past arrays of detectors stationed near future null infinity in the vacuum is considered. It is shown that the relative positions and clock times of the detectors before and after the radiation transit differ by a BMS supertranslation. An explicit expression for the supertranslation in terms of moments of the radiation energy flux is given. The relative spatial displacement found for a pair of nearby detectors reproduces the well-known and potentially measurable gravitational memory effect. The displacement memory formula is shown to be equivalent to Weinberg's formula for soft graviton production.

  2. Sharing good NEWS across the world: developing comparable scores across 12 countries for the neighborhood environment walkability scale (NEWS)

    PubMed Central

    2013-01-01

    Background The IPEN (International Physical Activity and Environment Network) Adult project seeks to conduct pooled analyses of associations of perceived neighborhood environment, as measured by the Neighborhood Environment Walkability Scale (NEWS) and its abbreviated version (NEWS-A), with physical activity using data from 12 countries. As IPEN countries used adapted versions of the NEWS/NEWS-A, this paper aimed to develop scoring protocols that maximize cross-country comparability in responses. This information is also highly relevant to non-IPEN studies employing the NEWS/NEWS-A, which is one of the most popular measures of perceived environment globally. Methods The following countries participated in the IPEN Adult study: Australia, Belgium, Brazil, Colombia, Czech Republic, Denmark, Hong Kong, Mexico, New Zealand, Spain, the United Kingdom, and the United States. Participants (N?=?14,305) were recruited from neighborhoods varying in walkability and socio-economic status. Countries collected data on the perceived environment using a self- or interviewer-administered version of the NEWS/NEWS-A. Confirmatory Factor Analysis (CFA) was used to derive comparable country-specific measurement models of the NEWS/NEWS-A. The level of correspondence between standard and alternative versions of the NEWS/NEWS-A factor-analyzable subscales was determined by estimating the correlations and mean standardized difference (Cohens d) between them using data from countries that had included items from both standard and alternative versions of the subscales. Results Final country-specific measurement models of the NEWS/NEWS-A provided acceptable levels of fit to the data and shared the same factorial structure with six latent factors and two single items. The correspondence between the standard and alternative versions of subscales of Land use mix access, Infrastructure and safety for walking/cycling, and Aesthetics was high. The Brazilian version of the Traffic safety subscale was highly, while the Australian and Belgian versions were marginally, comparable to the standard version. Single-item versions of the Street connectivity subscale used in Australia and Belgium showed marginally acceptable correspondence to the standard version. Conclusions We have proposed country-specific modifications to the original scoring protocol of the NEWS/NEWS-A that enhance inter-country comparability. These modifications have yielded sufficiently equivalent measurement models of the NEWS/NEWS-A. Some inter-country discrepancies remain. These need to be considered when interpreting findings from different countries. PMID:23566032

  3. More on soft theorems: Trees, loops, and strings

    2015-09-01

    We study soft theorems in a broader context, their universality in effective field theories and string theory, as well as continue the analysis of their fate at loop level. In effective field theories with F3 and R3 interactions, the soft theorems are not modified. However, for gravity theories with R2ϕ interactions, the sub-subleading order soft graviton theorem, which is beyond what is implied by the extended Bondi, van der Burg, Metzner, and Sachs symmetry, requires modifications at tree level for nonsupersymmetric theories and at loop level for N ≤4 supergravity due to anomalies. For open and closed superstrings at finite α', via explicit calculation for lower-point examples as well as world sheet operator product expansion analysis for arbitrary multiplicity, we show that scattering amplitudes satisfy the same soft theorem as their field-theory counterpart. This is no longer true for closed bosonic or heterotic strings due to the presence of R2ϕ interactions. We also consider loop corrections to gauge theories in the planar limit, where we show that tree-level soft gluon theorems are respected at the integrand level for 1 ≤N ≤4 SYM. Finally, we discuss the fate of soft theorems for finite loop amplitudes in pure Yang-Mills theory and gravity.

    The media environment of the future may be dramatically different from what exists today. As new computing and communications technologies evolve and synthesize to form a global, integrated communications system of networks, public domain hardware and software, and consumer products, it will be possible for citizens to fulfill most information needs at any time and from any place, to obtain desired information easily and quickly, to obtain information in a variety of forms, and to experience and interact with information in a variety of ways. This system will transform almost every institution, every profession, and every aspect of human life--including the creation, packaging, and distribution of news and information by media organizations. This paper presents one vision of a 21st century global information system and how it might be used by citizens. It surveys some of the technologies now on the market that are paving the way for new media environment.

    Understanding the spin structure of the nucleon in terms of quarks and gluons has been a challenging endeavor for more than 25 years. The quark's contribution to the spin of the nucleon is well established and amounts to about 30% of 1/2[h-bar]. The study of gluon contributions and orbital angular momenta has been the main experimental (and theoretical) focus in recent years. New results of single-spin asymmetries in semi-inclusive deep-inelastic scattering will be presented. The Sivers- and Collins-Effects were investigated using asymmetries in pion electro-production off transversely polarized helium-3 targets.

  11. A Functional Conceptualization of Understanding Science in the News

    NASA Astrophysics Data System (ADS)

    Anderson, Megan M.

    The idea that the public should have the capacity for understanding science in the news has been embraced by scientists, educators, and policymakers alike. An oft-cited goal of contemporary science education, in fact, is to enhance students' understanding of science in the news. But what exactly does it mean to understand science in the news? Surprisingly few have asked this question, or considered the significance of its answer. This dissertation steps away from issues of science teaching and learning to examine the nature of understanding science in the news itself. My work consolidates past scholarship from the multiple fields concerned with the relationship between science and society to produce a theoretical model of understanding science in the news as a complex, multidimensional process that involves an understanding of science as well as journalism. This thesis begins by exploring the relationship between the understanding implicit in understanding science in the news and understanding science. Many assume these two ways of knowing are one in the same. To rebut this assumption, I examine the types of knowledge necessary for understanding science and understanding science in the news. I then use the literature devoted to scientific literacy to show how past research has imagined the knowledge necessary to understand science in the news. Next, I argue that one of the principle difficulties with these conceptualizations is that they define science in the news in essentially the same terms as science. They also, I suggest, oversimplify how and why public interacts with science in the news. This dissertation concludes with a proposal for one way we might think about understanding science in the news on its own terms rather than those of understanding science. This dissertation attempts to connect two fields of research that rarely intersect, despite their multiple common interests: science education and mass communication. It considers the notion of understanding science in the news in light of the principles of each, rather than maintaining their distinction.

  13. Soft nanotechnology: "structure" vs. "function".

    Whitesides, George M; Lipomi, Darren J

    2009-01-01

    This paper offers a perspective on "soft nanotechnology"; that is, the branch of nanotechnology concerned with the synthesis and properties of organic and organometallic nanostructures, and with nanofabrication using techniques in which soft components play key roles. It begins with a brief history of soft nanotechnology. This history has followed a path involving a gradual shift from the promise of revolutionary electronics, nanorobotics, and other futuristic concepts, to the realization of evolutionary improvements in the technology for current challenges in information technology, medicine, and sustainability. Soft nanoscience is an area that is occupied principally by chemists, and is in many ways indistinguishable from "nanochemistry". The paper identifies the natural tendency of its practitioners--exemplified by the speakers at this Faraday Discussion--to focus on synthesis and structure, rather than on function and application, of nanostructures. Soft nanotechnology has the potential to apply to a wide variety of large-scale applied (information technology, healthcare cost reduction, sustainability, energy) and fundamental (molecular biochemistry, cell biology, charge transport in organic matter) problems.

    2015-02-01

    Soft tissue sarcomas are a group of rare tumors derived from mesenchymal tissue, accounting for about 1% of adult cancers. There are over 60 different histological subtypes, each with their own unique biological behavior and response to systemic therapy. The outcome for patients with metastatic soft tissue sarcoma is poor with few available systemic treatment options. For decades, the mainstay of management has consisted of doxorubicin with or without ifosfamide. Trabectedin is a synthetic agent derived from the Caribbean tunicate, Ecteinascidia turbinata. This drug has a number of potential mechanisms of action, including binding the DNA minor groove, interfering with DNA repair pathways and the cell cycle, as well as interacting with transcription factors. Several phase II trials have shown that trabectedin has activity in anthracycline and alkylating agent-resistant soft tissue sarcoma and suggest use in the second- and third-line setting. More recently, trabectedin has shown similar progression-free survival to doxorubicin in the first-line setting and significant activity in liposarcoma and leiomyosarcoma subtypes. Trabectedin has shown a favorable toxicity profile and has been approved in over 70 countries for the treatment of metastatic soft tissue sarcoma. This manuscript will review the development of trabectedin in soft tissue sarcomas. PMID:25686274

    Recommending news stories to users, based on their preferences, has long been a favourite domain for recommender systems research. Traditional systems strive to satisfy their user by tracing users' reading history and choosing the proper candidate news articles to recommend. However, most of news websites hardly require any user to register before reading news. Besides, the latent relations between news and microblog, the popularity of particular news, and the news organization are not addressed or solved efficiently in previous approaches. In order to solve these issues, we propose an effective personalized news recommendation method based on microblog user profile building and sub class popularity prediction, in which we propose a news organization method using hybrid classification and clustering, implement a sub class popularity prediction method, and construct user profile according to our actual situation. We had designed several experiments compared to the state-of-the-art approaches on a real world dataset, and the experimental results demonstrate that our system significantly improves the accuracy and diversity in mass text data.

    Bulk anisotropic composite magnets based on MnBi/Co(Fe) exhibiting the different morphology of the soft magnetic phase were prepared by powder metallurgy processing. First, single-phase MnBi bulk magnets were produced using a maximum energy product [(BH)m] of 6.3 MGOe at room temperature. The nanoscale soft phase with the different morphology was then added to form a composite magnet. It was observed that addition of magnetic soft-phase nanoparticles and nanoflakes causes a dramatic coercivity reduction. However, the addition of soft magnetic phase nanowires enhanced the composite magnetization without sacrificing the coercivity. Nevertheless, a kink was still observed on the demagnetization curves and the coercivity decreased when the soft-phase content was larger than 10 wt. %, which was caused by the agglomeration of the soft phase nanowires that also led to a decreased degree of texture.

    This paper summarizes recent evidence on what achievement tests measure; how achievement tests relate to other measures of “cognitive ability” like IQ and grades; the important skills that achievement tests miss or mismeasure, and how much these skills matter in life. Achievement tests miss, or perhaps more accurately, do not adequately capture, soft skills—personality traits, goals, motivations, and preferences that are valued in the labor market, in school, and in many other domains. The larger message of this paper is that soft skills predict success in life, that they causally produce that success, and that programs that enhance soft skills have an important place in an effective portfolio of public policies.

    Viscoelasticity is the primary mechanical property of bio-soft tissues. It has been widely applied in basic research of biological tissues including cornea, lung, heart and blood vessels. Along with the development of tissue engineering research, the evaluation of soft tissue viscoelasticity is becoming more and more important. In this paper, using the Whittaker function, we give an approximate power series of the exponential integral E 1( X) and the parameters C, ?1 and ?2 of the generalized relaxation function G(t) and generalized creep function J(t). With expanded skin as an example, the relationship between stress relaxation, creep and stress-strain finite deformation are studied.

    Taiwan's electronics industry emerged in the 1960s with the creation of a small but well planned integrated circuit (IC) packaging industry. This industry investment led to bolder investments in research, laboratories, and the island's first semiconductor foundries in the 1980s. Following the success of the emerging IC manufacturers and design houses, hundreds of service firms and related industries (software, legal services, substrate, chemical, and test firms among others) opened for business and completed Taiwan's IC manufacturing supply chain. The challenge for Taiwan's electronics industry is to take the lead in the design, manufacture, and marketing of name brand electronic products. This paper introduces the Si-Soft (silicon software) Project, a national initiative that builds on Taiwan's achievements in manufacturing (referred to as Si-Hard or silicon hardware) to launch a new wave of companies. These firms will contribute to the core underlying technology (intellectual property) used in the creation of electronic products.

    Prepackaged video news releases are being increasingly used to motivate television stations to cover stories in medicine and public health in their news programs. On Feb 26, 1987, the Office on Smoking and Health, US Department of Health and Human Services, distributed a prepackaged video news release to television stations across the country, calling attention to the new health warnings required on smokeless tobacco packages and advertisements. The video was sent by satellite as well as by overnight mail to selected stations. To assess the use of the video, we surveyed 76 stations that had been targeted by special intervention. These stations were in major metropolitan areas in states with a higher prevalence of smokeless tobacco use. Seventeen (22.4%) of the stations aired the story using our video during the six days following the satellite feed, reaching an estimated 2.8 million households. Another 20 stations reported that they were holding the video for use in the near future or for file footage. We conclude that the distribution of prepackaged video news stories can be an effective, relatively inexpensive technique to communicate health information to a large audience. PMID:3339801

    Many types of products and systems that have traditionally featured physical control devices are now being designed with soft controls--input formats appearing on computer-based display devices and operated by a variety of input devices. A review of complex human-machine systems found that soft controls are particularly prone to some types of errors and may affect overall system performance and safety. This paper discusses the application of design approaches for reducing the likelihood of these errors and for enhancing usability, user satisfaction, and system performance and safety.

    Computer-synthesized shadows used to appear with a sharp edge when cast onto a surface. At present the production of more realistic, soft shadows is considered. However, significant costs arise in connection with such a representation. The current investigation is concerned with a pragmatic approach, which combines an existing shadowing method with a popular visible surface rendering technique, called a 'depth buffer', to generate soft shadows resulting from light sources of finite extent. The considered method represents an extension of Crow's (1977) shadow volume algorithm.

  12. Improved scales for metal ion softness and toxicity.

    Kinraide, Thomas B

    2009-03-01

    Ten scales relating to chemical hardness or softness of metal ions were compiled. These included eight published scales such as those of Pearson, Ahrland, Klopman, and Misono. Another scale consisted of the logs of the solubility products of metal sulfides, and yet another was a consensus scale constructed from -log K values for metal ion binding to seven soft ligands. These 10 scales were normalized and averaged. The resulting consensus scale for softness (sigma(Con)) appeared to be superior to any of the 10 scales used in its construction based on correlations among the scales. Other possible indicators of softness were examined, including the standard electrode potential (E(0)) and the bulk metal density (rho(Metal)), both of which were also superior to most of the 10 scales just mentioned. Vales for sigma(Con) may be computed from E(0), rho(Metal), and the first ionization potential (I(P)), R(2) = 0.867, for the equation sigma(Con) = aE(0)I(P) + brho(Metal). A consensus scale for toxicity (T(Con)) derived from studies with many different taxa correlated well (R(2) = 0.807) with sigma(Con) computed from the preceding equation, but incorporation of ion charge (Z) into the following equation, T(Con) = asigma(Con) + bsigma(Con)Z + cZ, increased R(2) to 0.923. Substitution of other softness scales for sigma(Con) into equations to predict T(Con) reduced the value of R(2). Thus, sigma(Con) appears to be a superior scale for metal ion softness and toxicity, the latter being an interactive function of both softness and charge. PMID:18980392
