  2. Efforts and success world-wide in the field of clinical pharmacology. A personal review on the occasion of Folke Sjöqvist's 80th birthday.

    Science.gov (United States)

    Orme, Michael

    2013-05-01

    In this personal review I describe my early expectations and experiences when I first came to work with Prof. Folke Sjöqvist as a training fellow in the early 1970s. At that time Prof. Sjöqvist and his unit had already earned an international reputation, and in the following decades this success has been magnified many times. Although a description of the research performed by Prof. Sjöqvist during his long career is not the main objective of this article, it is clear that the research carried out in his unit has been instrumental in the development of his international reputation. Over an 18-year period from 1994 onwards, some 272 papers bearing the name of Folke Sjöqvist have been cited over 13,000 times, with an average of over 50 citations per paper. In terms of training clinical pharmacologists from around the world, at the last count 112 individuals from 37 different countries have received a substantial part of their training in his unit. As another measure of his world-wide success, 33 individuals from 18 different countries who received a substantial part of their training in his unit between 1968 and 1996 have gone on to become professors of clinical pharmacology. Prof. Sjöqvist has been requested to consult on various aspects of clinical pharmacology in 15 different countries, from Russia to Spain and from Egypt to Latvia. Here I describe the long-term involvement that Prof. Sjöqvist has had with IUPHAR (now the International Union of Basic and Clinical Pharmacology) and with institutions such as the World Health Organisation (WHO). In particular, I recount his role in the long-term saga involved in updating the original WHO manifesto on clinical pharmacology published in 1970 up to the eventual success of the new manifesto published by WHO in 2012. Finally, I briefly describe the international honours that have been bestowed on Prof. Sjöqvist, including various prizes, designated lectureships and honorary Doctorates (5). Taken together, these

  18. Golden Jubilee Photos: World Wide Web

    CERN Multimedia

    2004-01-01

    At the end of the 1980s, the Internet was already a valuable tool to scientists, allowing them to exchange e-mails and to access powerful computers remotely. A more simple means of sharing information was needed, however, and CERN, with its long tradition of informatics and networking, was the ideal place to find it. Moreover, hundreds of scientists from all over the world were starting to work together on preparations for the experiments at the Large Electron-Positron (LEP) collider. In 1989, Tim Berners-Lee (see photo), a young scientist working at CERN, drafted a proposal for an information-management system combining the internet, personal computers and computer-aided document consultation, known as hypertext. In 1990 he was joined by Robert Cailliau and the weaving of the World Wide Web began in earnest, even though only two CERN computers were allocated to the task at the time. The Web subsequently underwent a steady expansion to include the world's main particle physics institutes. The Web was not the...

  19. World Wide Web Metasearch Clustering Algorithm

    Directory of Open Access Journals (Sweden)

    Adina LIPAI

    2008-01-01

    Full Text Available As the storage capacity and the processing speed of search engine is growing to keep up with the constant expansion of the World Wide Web, the user is facing an increasing list of results for a given query. A simple query composed of common words sometimes have hundreds even thousands of results making it practically impossible for the user to verify all of them, in order to identify a particular site. Even when the list of results is presented to the user ordered by a rank, most of the time it is not sufficient support to help him identify the most relevant sites for his query. The concept of search result clustering was introduced as a solution to this situation. The process of clustering search results consists of building up thematically homogenous groups from the initial list results provided by classic search tools, and using up characteristics present within the initial results, without any kind of predefined categories.

    CERN Document Server

    Haubold, H J

    2004-01-01

    The UN/ESA Workshops on Basic Space Science is a long-term effort for the development of astronomy and regional and international co-operation in this field on a world wide basis, particularly in developing nations. The first four workshops in this series (India 1991, Costa Rica and Colombia 1992, Nigeria 1993, and Egypt 1994) addressed the status of astronomy in Asia and the Pacific, Latin America and the Caribbean, Africa, and Western Asia, respectively. One major recommendation that emanated from the first four workshops was that small astronomical facilities should be established in developing nations for research and education programmes at the university level and that such facilities should be networked. Subsequently, material for teaching and observing programmes for small optical telescopes were developed or recommended and astronomical telescope facilities have been inaugurated at UN/ESA Workshops on Basic Space Science in Sri Lanka (1995), Honduras (1997), and Jordan (1999). UN/ESA Workshops on Bas...

    2007-01-01

    The results are in, and the winner is...the World Wide Web! An online survey conducted by the CNN news group ranks the World Wide Web-invented at CERN--as the most wonderful of the seven modern wonders of the world. (See Bulletin No. 49/2006.) There is currently no speculation about whether they would have had the same results had they distributed the survey by post. The World Wide Web won with a whopping 50 per cent of the votes (3,665 votes). The runner up was CERN again, with 16 per cent of voters (1130 votes) casting the ballot in favour of the CERN particle accelerator. Stepping into place behind CERN and CERN is 'None of the Above' with 8 per cent of the votes (611 votes), followed by the development of Dubai (7%), the bionic arm (7%), China's Three Gorges Damn (5%), The Channel Tunnel (4%), and France's Millau viaduct (3%). Thanks to everyone from CERN who voted. You can view the results on http://edition.cnn.com/SPECIALS/2006/modern.wonders/

  3. Geomorphology and the World Wide Web

    Science.gov (United States)

    Shroder, John F.; Bishop, Michael P.; Olsenholler, Jeffrey; Craiger, J. Philip

    2002-10-01

    The Internet and the World Wide Web have brought many dimensions of new technology to education and research in geomorphology. As with other disciplines on the Web, Web-based geomorphology has become an eclectic mix of whatever material an individual deems worthy of presentation, and in many cases is without quality control. Nevertheless, new electronic media can facilitate education and research in geomorphology. For example, virtual field trips can be developed and accessed to reinforce concepts in class. Techniques for evaluating Internet references helps students to write traditional term papers, but professional presentations can also involve student papers that are published on the Web. Faculty can also address plagiarism issues by using search engines. Because of the lack of peer review of much of the content on the Web, care must be exercised in using it for reference searches. Today, however, refereed journals are going online and can be accessed through subscription or payment per article viewed. Library reference desks regularly use the Web for searches of refereed articles. Research on the Web ranges from communication between investigators, data acquisition, scientific visualization, or comprehensive searches of refereed sources, to interactive analyses of remote data sets. The Nanga Parbat and the Global Land Ice Measurements from Space (GLIMS) Projects are two examples of geomorphologic research that are achieving full potential through use of the Web. Teaching and research in geomorphology are undergoing a beneficial, but sometimes problematic, transition with the new technology. The learning curve is steep for some users but the view from the top is bright. Geomorphology can only prosper from the benefits offered by computer technologies.

  4. World wide web: opportunities, challenges, and threats.

    Edworthy, S M

    1999-01-01

    The Internet provides new opportunities to gather information on the population and may provide alternatives to the traditional methods of conducting clinical trials in systemic lupus erythematosus. The 'world wide web-www' has grown extensively in the past decade and it is estimated that there will be over 1 billion individuals on the net by the year 2005. Notifying, recruiting and assessing patients using Internet technology are already potential uses of this electronic medium. However, total reliance on the Internet could lead to biased sampling of patients with lupus. Women with low incomes or who are unemployed are less likely to have access to the Internet. Individuals with neurological deficits may have trouble using the Internet effectively. Data collected on the web may not have high reliability and much work needs to be completed to determine the psychometric properties of information derived from this source. One of the greatest threats to contend with is protecting the confidentiality of patient information when using electronic communication. Safeguards against inadvertent or unintended release of information must receive high priority in any attempt to use the Internet for clinical trials. Particular attention should be paid to email messages, which have the potential to be intercepted or sent to individuals without clearance to see patient information. Nevertheless, the costs to systems performance caused by security measures must also be considered and balanced against the need for access by those with appropriate authority. A number of websites already exist for the benefit of patients and providers. Clinicians and scientists interested in the field of lupus research will need to keep up to date on the rapidly proliferating information that is becoming available. This article lists sites which can be visited now.

  5. World's Biggest Astronomy Event on the World-Wide

    Science.gov (United States)

    1996-06-01

    `Astronomy On-Line' will connect students all over Europe Astronomy On-Line is a major, all-European project that will take place in conjunction with the 4th European Week for Scientific and Technological Culture later this year. It is based on intensive use of the World-Wide-Web (WWW) and represents the first large-scale attempt in the world to bring together pupils and their teachers all over one continent to explore challenging scientific questions, using modern communication tools, both for obtaining and for communicating information. The programme will be carried out in a collaboration between the European Association for Astronomy Education (EAAE) [1] and the European Southern Observatory, and together with the European Commission (EC). The active phase of Astronomy On-Line will start on October 1 and reach a climax on November 18 - 22, 1996 . What is `Astronomy On-Line'? In this project, a large number of students and their teachers at schools all over Europe, together with professional and amateur astronomers and others interested in astronomy, will become associated in a unique experience that makes intensive use of the vast possibilities of the World-Wide-Web (WWW). Although the exact number of participants will not be known until the beginning of October, it is expected to run into thousands, possibly many more. The unusual size and scope of Astronomy On-Line will contribute to make it an important all-European media event. The central idea is that the participants, through the WWW, will `meet' in a `marketplace' where a number of different `shops' will be available, each of which will tempt them with a number of exciting and educational `events', carefully prepared to cater for different age groups, from 12 years upwards. The events will cover a wide spectrum of activities, some of which will be timed to ensure the proper progression of this very complex project through its main phases. The benefits In fact, Astronomy On-Line will be the first

    Anglin, Richard L., Jr.

    1993-01-01

    Numbers of systems exist or have been proposed to provide world-wide mobile satellite services (MSS). Developers of these systems have formulated institutional structures they consider most appropriate for profitable delivery of these services. MSS systems provide niche services and complement traditional telecommunications networks; they are not integrated into world-wide networks. To be successful, MSS system operators must be able to provide an integrated suite of services to support the increasing globalization, interconnectivity, and mobility of business. The critical issue to enabling 'universal roaming' is securing authority to provide MSS in all of the nations of the world. Such authority must be secured in the context of evolving trends in international telecommunications, and must specifically address issues of standardization, regulation and organization. Today, only one existing organization has such world-wide authority. The question is how proponents of new MSS systems and services can gain similar authority. Securing the appropriate authorizations requires that these new organizations reflect the objectives of the nations in which services are to be delivered.

  9. Component-Based Software Reuse on the World Wide Web

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Component-based software reuse (CBSR) has been widely used in software developing practice and has an even more brilliant future with the rapid extension of the Internet, because World Wide Web (WWW) makes the large scale of component resources from different vendors become available to software developers. In this paper, an abstract component model suitable for representing components on WWW isproposed, which plays important roles both in achieving interoperability among components and amongreusable component libraries (RCLs). Some necessary changes to many aspects of component management brought by WWW are also discussed, such as the classification of components and the corresponding searching methods, and the certification of components.

    2014-01-01

    The ATLAS collaboration accounts for more than 3000 members located all over the world. The efficiency of the experiment can be improved allowing system experts not present on site to follow the ATLAS operations in real-time, spotting potential problems which otherwise may remain unattended for a non-negligible time. Taking into account the wide geographical spread of the ATLAS collaboration, the solution of this problem is to have all monitoring information with minimal access latency available world-wide. We have implemented a framework which defines a standard approach for retrieving arbitrary monitoring information from the ATLAS private network via HTTP. An information request is made by specifying one of the predefined URLs with some optional parameters refining data which has to be shipped back in XML format. The framework takes care of receiving, parsing and forwarding such requests to the appropriate plugins. The plugins retrieve the requested data and convert it to XML (or optionally to JSON) format...

    1998-05-01

    WIRED (World-Wide Web Interactive Remote Event Display) is a framework, written in the Java™ language, for building High Energy Physics event displays. An event display based on the WIRED framework enables users of a HEP collaboration to visualise and analyse events remotely using ordinary WWW browsers, on any type of machine. In addition, event displays using WIRED may provide the general public with access to the research of high energy physics. The recent introduction of the object-oriented Java™ language enables the transfer of machine independent code across the Internet, to be safely executed by a Java enhanced WWW browser. We have employed this technology to create a remote event display in WWW. The combined Java-WWW technology hence assures a world wide availability of such an event display, an always up-to-date program and a platform independent implementation, which is easy to use and to install.

    2002-01-01

    A basis for automatic discovery of information resources on the World Wide Web is characterized by three underlying equations. With these equations, the information universe on the Web is divided into three associated spaces. This model differs from the hypertext employed by the Web, in that the former supports the notion of automatic resource discovery. A private library, which is able to gather automatically from the Web the information useful to the library owner, is envisaged to illustrate that the basic equations and their derivations can be applied to Web automation, including crawling and classifying.

    2001-01-01

    Remote sensing education is increasingly in demand across academic and professional disciplines. Meanwhile, Internet technology and the World Wide Web (WWW) are being more frequently employed as teaching tools in remote sensing and other disciplines. The current wealth of information on the Internet and World Wide Web must be distilled, nonetheless, to be useful in remote sensing education. An extensive literature base is developing on the WWW as a tool in education and in teaching remote sensing. This literature reveals benefits and limitations of the WWW, and can guide its implementation. Among the most beneficial aspects of the Web are increased access to remote sensing expertise regardless of geographic location, increased access to current material, and access to extensive archives of satellite imagery and aerial photography. As with other teaching innovations, using the WWW/Internet may well mean more work, not less, for teachers, at least at the stage of early adoption. Also, information posted on Web sites is not always accurate. Development stages of this technology range from on-line posting of syllabi and lecture notes to on-line laboratory exercises and animated landscape flyovers and on-line image processing. The advantages of WWW/Internet technology may likely outweigh the costs of implementing it as a teaching tool.

    2013-02-01

    The World Wide Web is increasingly becoming an important source of information for healthcare professionals. However, finding reliable information from unauthoritative Web sites to inform healthcare can pose a challenge to nurses. A study, using grounded theory, was undertaken in two phases to understand how qualified nurses judge the quality of Web nursing information. Data were collected using semistructured interviews and focus groups. An explanatory framework that emerged from the data showed that the judgment process involved the application of forms of knowing and modes of cognition to a range of evaluative tasks and depended on the nurses' critical skills, the time available, and the level of Web information cues. This article mainly focuses on the six evaluative tasks relating to assessing user-friendliness, outlook and authority of Web pages, and relationship to nursing practice; appraising the nature of evidence; and applying cross-checking strategies. The implications of these findings to nurse practitioners and publishers of nursing information are significant.

    1994-01-01

    On January 14, 1993, NASA Langley Research Center (LaRC) made approximately 130 formal, 'unclassified, unlimited' technical reports available via the anonymous FTP Langley Technical Report Server (LTRS). LaRC was the first organization to provide a significant number of aerospace technical reports for open electronic dissemination. LTRS has been successful in its first 18 months of operation, with over 11,000 reports distributed and has helped lay the foundation for electronic document distribution for NASA. The availability of World Wide Web (WWW) technology has revolutionized the Internet-based information community. This paper describes the transition of LTRS from a centralized FTP site to a distributed data model using the WWW, and suggests how the general model for LTRS can be applied to other similar systems.

    2010-01-01

    Digital planetariums can provide a broader range of educational experiences than the more classical planetariums that use star-balls. This is because of their ability to project images, content from current research and the 3D distribution of the stars and galaxies. While there are hundreds of planetariums in the country the reason that few of these are full digital is the cost. In collaboration with Microsoft Research (MSR) we have developed a way to digitize existing planetariums for approximately \\$40,000 using software freely available. We describe here how off the shelf equipment, together with MSR's WorldWide Telescope client can provide a rich and truly interactive experience. This will enable students and the public to pan though multi-wavelength full-sky scientific data sets, explore 3d visualizations of our Solar System (including trajectories of millions of minor planets), near-by stars, and the SDSS galaxy catalog.

An electronic periodical is usually defined as a regular publication on some particular topic distributed in digital form, chiefly through the Web, but also by electronic mail or digital disk. The author has surveyed 106 publications. Thirty-four are distributed only on the Web, and 72 have printed versions. The number of analysed publications is not very big, but four years of electronic publishing and the variety of periodicals enables us to establish the causes of this phenomenon, the main features of development, and some perspectives. Electronic periodicals were analysed according to their type, purpose, contents, publisher, regularity, language, starting date and place of publication, and other features.

    A mass of heterogeneous, distributed and dynamic information on the World Wide Web (the Web) has resulted in "information overload". It's an important and urgent research issue to provide users with effective information retrieval service on the Web. Web search engines attempt to solve this problem, yet their effect is far from satisfying. In this paper, a distributed and cooperative strategy for information retrieval on the Web is proposed to substitute the centralized mode adopted by the current search engines. Then a new information retrieval system model IRSM is presented, which supports the retrieval of metadata about Web documents and uses Z39.50 standard protocol to unify the heterogeneous interfaces of different systems. Based on that, a distributed and cooperative information retrieval framework, called DCIRF, is designed to help users in fast and effective information retrieval on the Web.

    This project aims to improve astronomy education at the high school level, and to increase awareness in astronomy for pre-university students, on an international scale. In 2013, the WorldWide Telescope Ambassadors Program began a collaboration with the International Olympiad in Astronomy and Astrophysics (IOAA), which was held in the city of Volos, Greece in August 2013. Now at its VIIth edition, IOAA is the largest annual astronomy competition for high school students, and it consists of one team task and three individual ones - Theoretical, Data Analysis, and Observational. Each of the participating countries (35 in 2013, compared to 21 in 2007) is responsible for selecting up to five representative students for the International round. IOAA is meant to promote future collaborations between these students, and to encourage friendships inside a global scientific community. Ana-Maria Constantin, a current Harvard undergraduate student and a former medalist of IOAA, represented WorldWide Telescope Ambassadors in Greece by giving a talk on the advantages of using WWT as a tool for research and education. As a result, the President and the International Board of the Olympiad have expressed support for including WWT in the competition for future editions. WWTA is working with the Organizing Board for next year’s competition in Romania, to include WWT as a testing tool. This poster will summarize key points from the WWTA presentation in Greece, present ideas for WWT-based activities in future IOAA competitions, and outline plans for new collaborations from representatives of Sri Lanka, Poland, Bangladesh, and Colombia. Given the positive feedback we have received after the presentation in Greece, we are also considering future implementations of WWT in summer research camps for high school students, such as the Summer Science Program.

    The Great World Wide Star Count is an international field campaign encouraging participants to go outside, look skyward after dark, count the stars they see in certain constellations, and report what they see online. This Windows to the Universe citizen science event is designed to raise awareness about light pollution and the night sky as well as promote learning in astronomy. Star Count benefits from the current excitement in citizen science. The 2007 pilot effort included 15 nights for observations in October & November. Utilizing the international networking capabilities of Windows to the Universe, Star Count is able to engage people from all countries. Data collection and online reporting is designed to be simple and user-friendly for citizen scientists of all ages. The collected data is available online in a variety of formats for use by students, teachers and scientists worldwide to assess how the quality of the night sky varies around the world. This session will share our results and demonstrate how students and scientists worldwide can explore and analyze the data from the of the 2007 campaign. We will discuss how the Star Count team planned and executed the project in such a way that non-astronomers were able to make valid and useful contributions. We will also discuss lessons learned and best practices based on this inaugural campaign, as well as our plans for the future, including IYA 2009.

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer and technology awareness applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The NASA Technical Report Server (NTRS) provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people.

    Full Text Available Two methods were employed in this study of the use of the World Wide Web by business: first, a sample of 300 businesses with Web sites, across a wide range of industry types, was examined, by selecting (rather than sampling companies from the Yahoo! directory. The sites were investigated in relation to several areas - the purpose of the Web site, the use being made of electronic mail and the extent to which multi-media was being utilised. In addition, any other aspects of the site which were designed to make it more interesting to potential customers were also noted. Secondly, an electronic-mail questionnaire was sent to 222 of the 300 companies surveyed: that is, those that provided an e-mail address for contact. 14 were returned immediately due to unknown addresses or technical problems. Of the remaining 208, 102 replies were received, five of which were of no relevance, leaving 97 completed questionnaires to examine; a response rate of 47%, which is surprisingly good for a survey of this kind.

    1991-06-01

    The problem of isolating radioactive wastes from the biosphere presents specialists in the earth sciences with some of the most complicated problems they have ever encountered. This is especially true for high-level waste (HLW), which must be isolated in the underground and away from the biosphere for thousands of years. The most widely accepted method of doing this is to seal the radioactive materials in metal canisters that are enclosed by a protective sheath and placed underground in a repository that has been carefully constructed in an appropriate rock formation. Much new technology is being developed to solve the problems that have been raised, and there is a continuing need to publish the results of new developments for the benefit of all concerned. Table 1 presents a summary of the various formations under investigation according to the reports submitted for this world wide review. It can be seen that in those countries that are searching for repository sites, granitic and metamorphic rocks are the prevalent rock type under investigation. Six countries have developed underground research facilities that are currently in use. All of these investigations are in saturated systems below the water table, except the United States project, which is in the unsaturated zone of a fractured tuff.

    The distribution of numbers in human documents is determined by a variety of diverse natural and human factors, whose relative significance can be evaluated by studying the numbers' frequency of occurrence. Although it has been studied since the 1880's, this subject remains poorly understood. Here, we obtain the detailed statistics of numbers in the World Wide Web, finding that their distribution is a heavy-tailed dependence which splits in a set of power-law ones. In particular, we find that the frequency of numbers associated to western calendar years shows an uneven behavior: 2004 represents a `singular critical' point, appearing with a strikingly high frequency; as we move away from it, the decreasing frequency allows us to compare the amounts of existing information on the past and on the future. Moreover, while powers of ten occur extremely often, allowing us to obtain statistics up to the huge 10^127, `non-round' numbers occur in a much more limited range, the variations of their frequencies being dram...

    We report preliminary results from an NSF-funded project to build, test, and research the impact of a WorldWide Telescope Visualization Lab (WWT Vizlab), meant to offer learners a deeper physical understanding of the causes of the Moon's phases. The Moon Phases VizLab is designed to promote accurate visualization of the complex, three dimensional Earth-Sun-Moon relationships required to understand the Moon's phases, while also providing opportunities for middle school students to practice critical science skills, like using models, making predictions and observations, and linking them in evidence-based explanations. In the VizLab, students use both computer-based models and lamp + ball physical models. We present findings from the first two phases of the study—one in which we compared learning gains from the WWT VizLab with a traditional two dimensional Moon phases simulator, and another in which we experimented with different ways of blending physical and virtual models in the classroom.

    The WorldWide Telescope computer program, released to researchers and the public as a free resource in 2008 by Microsoft Research, has changed the way the ever-growing Universe of online astronomical data is viewed and understood. The WWT program can be thought of as a scriptable, interactive, richly visual browser of the multi-wavelength Sky as we see it from Earth, and of the Universe as we would travel within it. In its web API format, WWT is being used as a service to display professional research data. In its desktop format, WWT works in concert (thanks to SAMP and other IVOA standards) with more traditional research applications such as ds9, Aladin and TOPCAT. The WWT Ambassadors Program (founded in 2009) recruits and trains astrophysically-literate volunteers (including retirees) who use WWT as a teaching tool in online, classroom, and informal educational settings. Early quantitative studies of WWTA indicate that student experiences with WWT enhance science learning dramatically. Thanks to the wealth ...

    Full Text Available Some content in multimedia resources can depict or evoke certain emotions in users. The aim of Emotional Information Retrieval (EmIR and of our research is to identify knowledge about emotional-laden documents and to use these findings in a new kind of World Wide Web information service that allows users to search and browse by emotion. Our prototype, called Media EMOtion SEarch (MEMOSE, is largely based on the results of research regarding emotive music pieces, images and videos. In order to index both evoked and depicted emotions in these three media types and to make them searchable, we work with a controlled vocabulary, slide controls to adjust the emotions’ intensities, and broad folksonomies to identify and separate the correct resource-specific emotions. This separation of so-called power tags is based on a tag distribution which follows either an inverse power law (only one emotion was recognized or an inverse-logistical shape (two or three emotions were recognized. Both distributions are well known in information science. MEMOSE consists of a tool for tagging basic emotions with the help of slide controls, a processing device to separate power tags, a retrieval component consisting of a search interface (for any topic in combination with one or more emotions and a results screen. The latter shows two separately ranked lists of items for each media type (depicted and felt emotions, displaying thumbnails of resources, ranked by the mean values of intensity. In the evaluation of the MEMOSE prototype, study participants described our EmIR system as an enjoyable Web 2.0 service.

  19. World-Wide Web Tools for Locating Planetary Images

    Kanefsky, Bob; Deiss, Ron (Technical Monitor)

    1995-01-01

    The explosive growth of the World-Wide Web (WWW) in the past year has made it feasible to provide interactive graphical tools to assist scientists in locating planetary images. The highest available resolution images of any site of interest can be quickly found on a map or plot, and, if online, displayed immediately on nearly any computer equipped with a color screen, an Internet connection, and any of the free WWW browsers. The same tools may also be of interest to educators, students, and the general public. Image finding tools have been implemented covering most of the solar system: Earth, Mars, and the moons and planets imaged by Voyager. The Mars image-finder, which plots the footprints of all the high-resolution Viking Orbiter images and can be used to display any that are available online, also contains a complete scrollable atlas and hypertext gazetteer to help locating areas. The Earth image-finder is linked to thousands of Shuttle images stored at NASA/JSC, and displays them as red dots on a globe. The Voyager image-finder plots images as dots, by longitude and apparent target size, linked to online images. The locator (URL) for the top-level page is http: //ic-www.arc.nasa.gov/ic/projects/bayes-group/Atlas/. Through the efforts of the Planetary Data System and other organizations, hundreds of thousands of planetary images are now available on CD-ROM, and many of these have been made available on the WWW. However, locating images of a desired site is still problematic, in practice. For example, many scientists studying Mars use digital image maps, which are one third the resolution of Viking Orbiter survey images. When they douse Viking Orbiter images, they often work with photographically printed hardcopies, which lack the flexibility of digital images: magnification, contrast stretching, and other basic image-processing techniques offered by off-the-shelf software. From the perspective of someone working on an experimental image processing technique for

  20. World-Wide Effort Produces Dramatic "Movie" of Cosmic Jet

    2001-05-01

    Astronomers using a world-wide collection of radio telescopes, including the National Science Foundation's Very Long Baseline Array (VLBA) of the National Radio Astronomy Observatory (NRAO), have made a dramatic "movie" of a voracious, superdense neutron star repeatedly spitting out subatomic particles at nearly the speed of light into two narrow jets as it pulls material from a companion star. The movie shows these jets ejecting clouds of hot plasma that are then "zapped" by pulses of energy in the jets as they move away from the neutron star. Frame from Radio-Telescope 'Movie' of Scorpius X-1 "We have directly measured the speed of energy flow in a cosmic jet for the first time," said Ed Fomalont, an astronomer at the NRAO in Charlottesville, Virginia. Fomalont worked with Barry Geldzahler and Charles Bradshaw of George Mason University in Fairfax, Virginia. The astronomers used the VLBA, the NSF's Very Large Array (VLA) and the Green Bank 140-foot telescope, along with radio telescopes from the European VLBI Network, Australia, Japan and South Africa to record the double-star system's eruptions continuously for 56 hours. "This study is going to be extremely valuable in helping us understand a phenomenon that we see throughout the universe," Fomalont said. Cosmic jets of superfast particles are ejected from the cores of numerous galaxies. On a smaller scale, similar jets are ejected from binary-star systems closer to home, in our own Milky Way Galaxy. While the jets from galaxy cores are thought to be powered by supermassive black holes millions of times more massive than the Sun, the closer "microquasars" are powered by much smaller black holes or by neutron stars only a few times more massive than the sun. "Studying one of the closer, smaller examples will help us understand how they all work, including the bigger ones," Geldzahler said. "The jets coming from distant galaxies are harder to study because of their much greater distance and the slowness of their

    2013-01-01

    The world-wide sensor web has become a very useful technique for monitoring the physical world at spatial and temporal scales that were previously impossible. Yet we believe that the full potential of sensor web has thus far not been revealed. In order to harvest the world-wide sensor web's full potential, a geospatial cyberinfrastructure is needed to store, process, and deliver large amount of sensor data collected worldwide. In this paper, we first define the issue of the sensor web long tail followed by our view of the world-wide sensor web architecture. Then, we introduce the Geospatial Cyberinfrastructure for Environmental Sensing (GeoCENS) architecture and explain each of its components. Finally, with demonstration of three real-world powered-by-GeoCENS sensor web applications, we believe that the GeoCENS architecture can successfully address the sensor web long tail issue and consequently realize the world-wide sensor web vision.

    Peterson, Randall L.; Warmbrodt, William (Technical Monitor)

    1996-01-01

    The tilt rotor aircraft holds great promise for improving air travel in the future. It's benefits include vertical take off and landing combined with airspeeds comparable to propeller driven aircraft. However, the noise from a tilt rotor during approach to a landing is potentially a significant barrier to widespread acceptance of these aircraft. This approach noise is primarily caused by Blade Vortex Interactions (BVI), which are created when the blade passes near or through the vortex trailed by preceding blades. The XV- 15 Aeroacoustic test will measure the noise from a tilt rotor during descent conditions and demonstrate several possible techniques to reduce the noise. The XV- 15 Aeroacoustic test at NASA Ames Research Center will measure acoustics and performance for a full-scale XV-15 rotor. A single XV-15 rotor will be mounted on the Ames Rotor Test Apparatus (RTA) in the 80- by 120-Foot Wind Tunnel. The test will be conducted in helicopter mode with forward flight speeds up to 100 knots and tip path plane angles up to +/- 15 degrees. These operating conditions correspond to a wide range of tilt rotor descent and transition to forward flight cases. Rotor performance measurements will be made with the RTA rotor balance, while acoustic measurements will be made using an acoustic traverse and four fixed microphones. The acoustic traverse will provide limited directionality measurements on the advancing side of the rotor, where BVI noise is expected to be the highest. Baseline acoustics and performance measurements for the three-bladed rotor will be obtained over the entire test envelope. Acoustic measurements will also be obtained for correlation with the XV-15 aircraft Inflight Rotor Aeroacoustic Program (IRAP) recently conducted by Ames. Several techniques will be studied in an attempt to reduce the highest measured BVI noise conditions. The first of these techniques will use sub-wings mounted on the blade tips. These subwings are expected to alter the size

    2010-01-01

    We identify the presence of Pet-Fish problem situations and the corresponding Guppy effect of concept theory on the World-Wide Web. For this purpose, we introduce absolute weights for words expressing concepts and relative weights between words expressing concepts, and the notion of 'meaning bound' between two words expressing concepts, making explicit use of the conceptual structure of the World-Wide Web. The Pet-Fish problem occurs whenever there are exemplars - in the case of Pet and Fish these can be Guppy or Goldfish - for which the meaning bound with respect to the conjunction is stronger than the meaning bounds with respect to the individual concepts.

    Full Text Available This year a prominent Ukrainian theoretical physicist and public leader Anatolij Svidzynskyj marks his 85th birthday. Anatolij Svidzynskyj was born on 1 March 1929 in Mohyliv-Podilskyy (Ukraine to a family of a physics teacher and an economist. Since 1939 and to the end of WWII Svidzynskyj's family lived in Kiev. In 1945 they moved to Lviv, where A. Svidzynskyj graduated from the Faculty of Physics and Mathematics of the Lviv State University. Vasyl Milyanchuk was his first supervisor. Due to his advice A. Svidzynskyj moved to Moscow State University where Mykola Boholiubov worked at the time. Under Bogoliubov's supervision the PhD thesis ``On the method of functional averaging in the theory of Green's function'' was written, which was defended in 1956 at Lviv State University. One of the most important results obtained in the thesis is an exact solution of Bloch-Nordsieck model that describes an infrared asymptotic of the electron Green's function in a realistic theory - quantum electrodynamics. In this way, a non-analytical dependence of this function on a coupling constant was obtained, and the nature of infrared divergences in quantum electrodynamics was clarified.

    2012-01-01

    With the advent of the World Wide Web, historic images previously having limited distributions are now widely available. As tobacco use has evolved, so have images of nurses related to smoking. Using a systematic search, the purpose of this article is to describe types of images of nurses and smoking available on the World Wide Web. Approximately 10,000 images of nurses and smoking published over the past century were identified through search engines and digital archives. Seven major themes were identified: nurses smoking, cigarette advertisements, helping patients smoke, "naughty" nurse, teaching women to smoke, smoking in and outside of health care facilities, and antitobacco images. The use of nursing images to market cigarettes was known but the extent of the use of these images has not been reported previously. Digital archives can be used to explore the past, provide a perspective for understanding the present, and suggest directions for the future in confronting negative images of nursing.

Black Monday on stock markets throughout the world - a new phenomenon of collective panic disorder? A psychiatric approach. Med Hypotheses 2008;71(6):972-4], which illustrate typical psychiatric symptoms of panic disorder. We now complete this model by a therapeutic approach for the patient. Therefore the identification of a therapeutic regime "step by step" was necessary.

His research interests cover various fields of condensed matter physics. In particular, he obtained important results in the theory of ferroelectrics, quantum liquids, critical phenomena in magnets and random systems, spin liquids, superconductors, and neural networks. Reinhard Folk and his collaborators performed a series of studies that became the basis for understanding and quantitative description of phenomena occurring in many systems. Included amongst these are the description of the thermodynamic properties of matter in the vicinity of Lifshitz points, the description of critical dynamics in systems with different types of conservation laws, the analysis of effective (non-asymptotic critical behaviour, and generalized hydrodynamics of many-particle systems. Computing algorithms, resummation methods of asymptotic perturbation series proposed by Reinhard Folk and his collaborators, cover a wide range of applications. In 1982 (together with Volker Dohm he was awarded the Walter Schottky Prize of the German Physical Society for his studies of the critical dynamics of helium-4 . Those of us who were fortunate to know Reinhard Folk closer, are aware of his interests in the history of culture and the history of

    Full Text Available The rapid expansion occurring in World-Wide Web activity is beginning to make the concepts of ‘global hypermedia’ and ‘universal document readership’ realistic objectives of the new revolution in information technology. One consequence of this increase in usage is that educators and students are becoming more aware of the diversity of the knowledge base which can be accessed via the Internet. Although computerised databases and information services have long played a key role in bioinformatics these same resources can also be used to provide core materials for teaching and learning. The large datasets and arch ives th at have been compiled for biomedical research can be enhanced with the addition of a variety of multimedia elements (images. digital videos. animation etc.. The use of this digitally stored information in structured and self-directed learning environments is likely to increase as activity across World-Wide Web increases.

  11. Do We Need to Impose More Regulation Upon the World Wide Web? -A Metasystem Analysis

    Directory of Open Access Journals (Sweden)

    John P. van Gigch

    2000-01-01

    Full Text Available Every day a new problem attributable to the World Wide Web's lack of formal structure and/or organization is made public. What arguably could be represented as one of its main strengths is rapidly turning out to be one of its most flagrant weaknesses. The intent of this article is to show the need to establish a more formal organization than presently exists over the World Wide Web. (This article will use the terms the Internet and Cyberspace interchangeably. It is proposed that this formal organization take the form of a metacontrol system--to be explained-- and rely, at least in part, for this control to self-regulate. The so-called metasystem system would be responsible for preventing some of the unanticipated situations that take place in cyberspace and that, due to the web's lack of maturity, have not been encountered heretofore. Some activities, such as the denial-of-service (DoS attacks, may well be illicit. Others, like the question of establishing a world-wide democratic board to administer the Internet's address system, are so new that there are no technical, legal or political precedents to ensure its design will succeed. What is needed is a formal, over-arching control system, i.e. a "metasystem," to arbitrate over controversies, decide on the legality of new policies and, in general, act as a metalevel controller over the activities of the virtual community called Cyberspace. The World Wide Web Consortium has emerged as a possible candidate for this role.This paper uses control theory to define both the problem and the proposed solution. Cyberspace lacks a metacontroller that can be used to resolve the many problems that arise when a new organizational configuration, such as the Internet, is created and when questions surface about the extent to which new activities interfere with individual or corporate freedoms.

  12. Embedded Web Technology: Applying World Wide Web Standards to Embedded Systems

    Ponyik, Joseph G.; York, David W.

    2002-01-01

    Embedded Systems have traditionally been developed in a highly customized manner. The user interface hardware and software along with the interface to the embedded system are typically unique to the system for which they are built, resulting in extra cost to the system in terms of development time and maintenance effort. World Wide Web standards have been developed in the passed ten years with the goal of allowing servers and clients to intemperate seamlessly. The client and server systems can consist of differing hardware and software platforms but the World Wide Web standards allow them to interface without knowing about the details of system at the other end of the interface. Embedded Web Technology is the merging of Embedded Systems with the World Wide Web. Embedded Web Technology decreases the cost of developing and maintaining the user interface by allowing the user to interface to the embedded system through a web browser running on a standard personal computer. Embedded Web Technology can also be used to simplify an Embedded System's internal network.

  14. Curvature of co-links uncovers hidden thematic layers in the World Wide Web.

    Science.gov (United States)

    Eckmann, Jean-Pierre; Moses, Elisha

    2002-04-30

    Beyond the information stored in pages of the World Wide Web, novel types of "meta-information" are created when pages connect to each other. Such meta-information is a collective effect of independent agents writing and linking pages, hidden from the casual user. Accessing it and understanding the interrelation between connectivity and content in the World Wide Web is a challenging problem [Botafogo, R. A. & Shneiderman, B. (1991) in Proceedings of Hypertext (Assoc. Comput. Mach., New York), pp. 63-77 and Albert, R. & Barabási, A.-L. (2002) Rev. Mod. Phys. 74, 47-97]. We demonstrate here how thematic relationships can be located precisely by looking only at the graph of hyperlinks, gleaning content and context from the Web without having to read what is in the pages. We begin by noting that reciprocal links (co-links) between pages signal a mutual recognition of authors and then focus on triangles containing such links, because triangles indicate a transitive relation. The importance of triangles is quantified by the clustering coefficient [Watts, D. J. & Strogatz, S. H. (1999) Nature (London) 393, 440-442], which we interpret as a curvature [Bridson, M. R. & Haefliger, A. (1999) Metric Spaces of Non-Positive Curvature (Springer, Berlin)]. This curvature defines a World Wide Web landscape whose connected regions of high curvature characterize a common topic. We show experimentally that reciprocity and curvature, when combined, accurately capture this meta-information for a wide variety of topics. As an example of future directions we analyze the neural network of Caenorhabditis elegans, using the same methods.

    Preferential attachment is the most popular explanation for the emergence of scaling behavior in the World Wide Web, but this explanation has been challenged by the global information hypothesis, the existence of linear preference and the emergence of new big internet companies in the real world. We notice that most websites have an obvious feature that their pages are organized as a tree (namely hidden tree) and hence propose a new model that introduces a hidden tree structure into the Erd(o)s-Rényi model by adding a new rule: when one node connects to another, it should also connect to all nodes in the path between these two nodes in the hidden tree. The experimental results show that the degree distribution of the generated graphs would obey power law distributions and have variable high clustering coefficients and variable small average lengths of shortest paths. The proposed model provides an alternative explanation to the emergence of scaling in the World Wide Web without the above-mentioned difficulties, and also explains the "preferential attachment" phenomenon.

    Wind energy is now being deployed world-wide at a rapidly increasing rate and the International Energy Agency (IEA) has a changing role in its growth. IEA was founded in 1974 within the framework of the Organization for Economic Cooperation and Development (OECD) to collaborate on comprehensive international energy programs. IEA membership consists of eighteen parties from sixteen countries and the European Commission. Recently there has been increasing interest in IEA participation from both OECD and non-OECD countries. Non-OECD countries participating in various IEA Agreements include: China, India, Israel, Korea, and Russia. Because of its diverse international makeup, the IEA is viewed as a source of reliable technical and economic information. The World Bank has approached the Executive Committee for Wind Energy R & D, through the IEA Renewable Energy Working Party, to assist in the expansion of wind deployment. In addition, IEA is moving from R & D programs to include tracking of implementation incentives offered by its members.

  1. Global Deliberative Democracy and Climate Change: Insights from World Wide Views on Global Warming in Australia

    Directory of Open Access Journals (Sweden)

    Chris Riedy

    2011-12-01

    Full Text Available On 26 September 2009, approximately 4,000 citizens in 38 countries participated in World Wide Views on Global Warming (WWViews. WWViews was an ambitious first attempt to convene a deliberative mini-public at a global scale, giving people from around the world an opportunity to deliberate on international climate policy and to make recommendations to the decision-makers meeting at the United Nations Climate Change Conference in Copenhagen (COP-15 in December 2009. In this paper, we examine the role that deliberative mini-publics can play in facilitating the emergence of a global deliberative system for climate change response. We pursue this intent through a reflective evaluation of the Australian component of the World Wide Views on Global Warming project (WWViews. Our evaluation of WWViews is mixed. The Australian event was delivered with integrity and feedback from Australian participants was almost universally positive. Globally, WWViews demonstrated that it is feasible to convene a global mini-public to deliberate on issues of global relevance, such as climate change. On the other hand, the contribution of WWViews towards the emergence of a global deliberative system for climate change response was limited and it achieved little influence on global climate change policy. We identify lessons for future global mini-publics, including the need to prioritise the quality of deliberation and provide flexibility to respond to cultural and political contexts in different parts of the world. Future global mini-publics may be more influential if they seek to represent discourse diversity in addition to demographic profiles, use designs that maximise the potential for transmission from public to empowered space, run over longer time periods to build momentum for change and experiment with ways of bringing global citizens together in a single process instead of discrete national events.

    As of 2015, about 20 million people have downloaded the computer program called "WorldWide Telescope," and even more have accessed it via the web, at http://worldwidetelescope.org. But, the vast majority of these millions are not professional astronomers. This talk will explain why WorldWide Telescope (WWT) is also a powerful tool for research astronomers. I will focus on how WWT can be, and is, being built-in to Journals, and into day-to-day research environments. By way of example, I will show how WWT already: allows users to display images, including those in Journals, in the context of multi-wavelength full-sky imagery; allows for the display of which parts of the Sky have been studied, when, how, and for what reason (see http://adsass.org); allows, via right-click, immediate access to ADS, SIMBAD, and other professional research tools. I will also highlight new work, currently in development, that is using WWT as a tool for observation planning, and as a display mode for advanced high-dimensional data visualization tools, like glue (see http://glueviz.org). WWT is now well-known in the education community (see http://wwtambassadors.org), so the explicit goal of this talk will be to make researchers more aware of its full power. I will explain how WWT transitioned, over 8 years, from a Microsoft Research project to its current open-source state (see https://github.com/WorldWideTelescope), and I will conclude with comments on the future of WWT, and its relationship to how research should be carried out in the future (see http://tinyurl.com/aas-potf).

    1999-09-01

    Higher education is moving with deliberate speed to an electronic classroom. Much has been published on faculty experiences with World Wide Web (WWW) course delivery. However, little research exists on the evaluation of these methods. The purpose of this study was to evaluate students' perceptions of two approaches to teaching: classroom and WWW modules. Classroom methods were rated significantly higher in relation to content, interaction, participation, faculty preparation, and communication. Technical skills were rated higher for WWW modules. Critical thinking and time allotted for assignments were not significantly different between classroom and WWW instruction. Open-ended comments were rich and supported both positive and negative aspects of classroom and WWW-based modules. Implications call for creativity in course development, course redesign and orientation, active communication with students, support for technical problems, faculty development, and university-wide planning through partnerships.

  15. World-wide association of timberline forest advance with microsite type along a precipitation gradient

    Science.gov (United States)

    Johnson, A. C.; Yeakley, A.

    2009-12-01

    Timberline forest advance associated with global climate change is occurring worldwide and is often associated with microsites. Microsites, controlled by topography, substrates, and plant cover, are localized regions dictating temperature, moisture, and solar radiation. These abiotic factors are integral to seedling survival. From a compilation of world-wide information on seedling regeneration on microsites at timberline, including our on-going research in the Pacific Northwest, we classified available literature into four microsite categories, related microsite category to annual precipitation, and used analysis of variance to detect statistical differences in microsite type and associated precipitation. We found statistical differences (p = 0.022) indicating the usefulness of understanding microsite/precipitation associations in detecting world-wide trends in timberline expansion. For example, wetter timberlines with downed wood, had regeneration associated with nurse logs, whereas on windy, drier landscapes, regeneration was typically associated with either leeward sides of tree clumps or on microsites protected from frost by overstory canopy. In our study of timberline expansion in the Pacific Northwest, we expect that such knowledge of microsite types associated with forest expansion will reveal a better understanding of mechanisms and rates of timberline forest advance during global warming.

    Geneva, 13 March 2009. Web inventor Tim Berners-Lee returned to the birthplace of his invention today, 20 years after submitting his paper ‘Information Management: A Proposal’ to his boss Mike Sendall. By writing the words ‘Vague, but exciting’ on the document’s cover, and giving Berners-Lee the go-ahead to continue, Sendall was signing into existence the information revolution of our times: the World Wide Web. In September of the following year, Berners-Lee took delivery of a computer called a NeXT cube, and by December the Web was up and running, albeit between just a couple of computers at CERN1. Today’s event takes a look back at some of the early history, and pre-history, of the World Wide Web at CERN, includes a keynote speech from Tim Berners-Lee, and concludes with a series of talks from some of today’s Web pioneers. “It’s a pleasure to be back at CERN today,” said Berners-Lee. “CERN has come a long way since 1989, and so has the Web, but its roots will always be here.” The Wo...

  17. WorldWide Telescope: A Newly Open Source Astronomy Visualization System

    Science.gov (United States)

    Fay, Jonathan; Roberts, Douglas A.

    2016-01-01

    After eight years of development by Microsoft Research, WorldWide Telescope (WWT) was made an open source project at the end of June 2015. WWT was motivated by the desire to put new surveys of objects, such as the Sloan Digital Sky Survey in the context of the night sky. The development of WWT under Microsoft started with the creation of a Windows desktop client that is widely used in various education, outreach and research projects. Using this, users can explore the data built into WWT as well as data that is loaded in. Beyond exploration, WWT can be used to create tours that present various datasets a narrative format.In the past two years, the team developed a collection of web controls, including an HTML5 web client, which contains much of the functionality of the Windows desktop client. The project under Microsoft has deep connections with several user communities such as education through the WWT Ambassadors program, http://wwtambassadors.org/ and with planetariums and museums such as the Adler Planetarium. WWT can also support research, including using WWT to visualize the Bones of the Milky Way and rich connections between WWT and the Astrophysical Data Systems (ADS, http://labs.adsabs.harvard.edu/adsabs/). One important new research connection is the use of WWT to create dynamic and potentially interactive supplements to journal articles, which have been created in 2015.Now WWT is an open source community lead project. The source code is available in GitHub (https://github.com/WorldWideTelescope). There is significant developer documentation on the website (http://worldwidetelescope.org/Developers/) and an extensive developer workshops (http://wwtworkshops.org/?tribe_events=wwt-developer-workshop) has taken place in the fall of 2015.Now that WWT is open source anyone who has the interest in the project can be a contributor. As important as helping out with coding, the project needs people interested in documentation, testing, training and other roles.

  18. Health information seeking and the World Wide Web: an uncertainty management perspective.

    Science.gov (United States)

    Rains, Stephen A

    2014-01-01

    Uncertainty management theory was applied in the present study to offer one theoretical explanation for how individuals use the World Wide Web to acquire health information and to help better understand the implications of the Web for information seeking. The diversity of information sources available on the Web and potential to exert some control over the depth and breadth of one's information-acquisition effort is argued to facilitate uncertainty management. A total of 538 respondents completed a questionnaire about their uncertainty related to cancer prevention and information-seeking behavior. Consistent with study predictions, use of the Web for information seeking interacted with respondents' desired level of uncertainty to predict their actual level of uncertainty about cancer prevention. The results offer evidence that respondents who used the Web to search for cancer information were better able than were respondents who did not seek information to achieve a level of uncertainty commensurate with the level of uncertainty they desired.

    Callahan, John; Ramakrishnan, Sudhaka

    1996-01-01

    We briefly describe a system for forms-based, work-flow management that helps members of a software development team overcome geographical barriers to collaboration. Our system, called the Web Integrated Software Environment (WISE), is implemented as a World-Wide-Web service that allows for management and measurement of software development projects based on dynamic analysis of change activity in the workflow. WISE tracks issues in a software development process, provides informal communication between the users with different roles, supports to-do lists, and helps in software process improvement. WISE minimizes the time devoted to metrics collection and analysis by providing implicit delivery of messages between users based on the content of project documents. The use of a database in WISE is hidden from the users who view WISE as maintaining a personal 'to-do list' of tasks related to the many projects on which they may play different roles.

    Sun, Charles; Windrem, May; Givens, John J. (Technical Monitor)

    1998-01-01

    World Wide Web (W3) technologies such as the Hypertext Transfer Protocol (HTTP) and the Java object-oriented programming environment offer a powerful, yet relatively inexpensive, framework for distributed application software development. This paper describes the design of a real-time payload control and monitoring system that was developed with W3 technologies at NASA Ames Research Center. Based on Java Development Toolkit (JDK) 1.1, the system uses an event-driven "publish and subscribe" approach to inter-process communication and graphical user-interface construction. A C Language Integrated Production System (CLIPS) compatible inference engine provides the back-end intelligent data processing capability, while Oracle Relational Database Management System (RDBMS) provides the data management function. Preliminary evaluation shows acceptable performance for some classes of payloads, with Java's portability and multimedia support identified as the most significant benefit.

  1. Educational use of World Wide Web pages on CD-ROM.

    Engel, Thomas P; Smith, Michael

    2002-01-01

    The World Wide Web is increasingly important for medical education. Internet served pages may also be used on a local hard disk or CD-ROM without a network or server. This allows authors to reuse existing content and provide access to users without a network connection. CD-ROM offers several advantages over network delivery of Web pages for several applications. However, creating Web pages for CD-ROM requires careful planning. Issues include file names, relative links, directory names, default pages, server created content, image maps, other file types and embedded programming. With care, it is possible to create server based pages that can be copied directly to CD-ROM. In addition, Web pages on CD-ROM may reference Internet served pages to provide the best features of both methods.

    The world-wide procurement of Nb3Sn and NbTi for the ITER superconducting magnet systems will involve eight to ten strand suppliers from six Domestic Agencies (DAs) on three continents. To ensure accurate and consistent measurement of the physical and superconducting properties of the composite strand, a strand test facility benchmarking effort was initiated in August 2008. The objectives of this effort are to assess and improve the superconducting strand test and sample preparation technologies at each DA and supplier, in preparation for the more than ten thousand samples that will be tested during ITER procurement. The present benchmarking includes tests for critical current (I-c), n-index, hysteresis loss (Q(hys)), residual resistivity ratio (RRR), strand diameter, Cu fraction, twist pitch, twist direction, and metal plating thickness (Cr or Ni). Nineteen participants from six parties (China, EU, Japan, South Korea, Russia, and the United States) have participated in the benchmarking. This round, conducted...

  3. Prototyping of Remote Experiment and Exercise Systems for an Engineering Education based on World Wide Web

    Iwatsuki, Masami; Kato, Yoriyuki; Yonekawa, Akira

    State-of-the-art Internet technologies allow us to provide advanced and interactive distance education services. However, we could not help but gather students for experiments and exercises in an education for engineering because large-scale equipments and expensive software are required. On the other hand, teleoperation systems with robot manipulator or vehicle via Internet have been developed in the field of robotics. By fusing these two techniques, we can realize remote experiment and exercise systems for the engineering education based on World Wide Web. This paper presents how to construct the remote environment that allows students to take courses on experiment and exercise independently of their locations. By using the proposed system, users can exercise and practice remotely about control of a manipulator and a robot vehicle and programming of image processing.

  4. Remote monitoring using technologies from the Internet and World Wide Web

    Energy Technology Data Exchange (ETDEWEB)

    Puckett, J.M.; Burczyk, L.

    1997-11-01

    Recent developments in Internet technologies are changing and enhancing how one processes and exchanges information. These developments include software and hardware in support of multimedia applications on the World Wide Web. In this paper the authors describe these technologies as they have applied them to remote monitoring and show how they will allow the International Atomic Energy Agency to efficiently review and analyze remote monitoring data for verification of material movements. The authors have developed demonstration software that illustrates several safeguards data systems using the resources of the Internet and Web to access and review data. This Web demo allows the user to directly observe sensor data, to analyze simulated safeguards data, and to view simulated on-line inventory data. Future activities include addressing the technical and security issues associated with using the Web to interface with existing and planned monitoring systems at nuclear facilities. Some of these issues are authentication, encryption, transmission of large quantities of data, and data compression.

    2002-09-01

    The World Wide Web (WWW) is continuing to grow exponentially both in terms of numbers of users and numbers of web pages. There is a trend toward the increasing use of the WWW for medical educational purposes, both among physicians and patients alike. The multimedia capabilities of this evolving medium are particularly relevant to visual medical specialties such as dermatology. The origins of information consumerism on the WWW are examined, and the public health issues surrounding dermatologic information and misinformation, and how consumers navigate through the WWW are reviewed. The economic realities of medical information as a "capital good," and the impact this has on dermatologic information sources on the WWW are also discussed.Finally, strategies for guiding consumers and ourselves toward credible medical information sources on the WWW are outlined.

  7. Using the World Wide Web to Connect Research and Professional Practice: Towards Evidence-Based Practice

    Directory of Open Access Journals (Sweden)

    Daniel L. Moody

    2003-01-01

    Full Text Available In most professional (applied disciplines, research findings take a long time to filter into practice, if they ever do at all. The result of this is under-utilisation of research results and sub-optimal practices. There are a number of reasons for the lack of knowledge transfer. On the "demand side", people working in professional practice have little time available to keep up with the latest research in their field. In addition, the volume of research published each year means that the average practitioner would not have time to read all the research articles in their area of interest even if they devoted all their time to it. From the "supply side", academic research is primarily focused on the production rather than distribution of knowledge. While they have highly developed mechanisms for transferring knowledge among themselves, there is little investment in the distribution of research results be-yond research communities. The World Wide Web provides a potential solution to this problem, as it provides a global information infrastructure for connecting those who produce knowledge (researchers and those who need to apply this knowledge (practitioners. This paper describes two projects which use the World Wide Web to make research results directly available to support decision making in the workplace. The first is a successful knowledge management project in a health department which provides medical staff with on-line access to the latest medical research at the point of care. The second is a project currently in progress to implement a similar system to support decision making in IS practice. Finally, we draw some general lessons about how to improve transfers of knowledge from research and practice, which could be applied in any discipline.

  8. Hierarchical structure of mitochondrial DNA gene flow among humpback whales Megaptera novaeangliae, world-wide.

    The genetic structure of humpback whale populations and subpopulation divisions is described by restriction fragment length analysis of the mitochondrial (mt) DNA from samples of 230 whales collected by biopsy darting in 11 seasonal habitats representing six subpopulations, or 'stocks', world-wide. The hierarchical structure of mtDNA haplotype diversity among population subdivisions is described using the analysis of molecular variance (AMOVA) procedure, the analysis of gene identity, and the genealogical relationship of haplotypes as constructed by parsimony analysis and distance clustering. These analyses revealed: (i) significant partitioning of world-wide genetic variation among oceanic populations, among subpopulations or 'stocks' within oceanic populations and among seasonal habitats within stocks; (ii) fixed categorical segregation of haplotypes on the south-eastern Alaska and central California feeding grounds of the North Pacific; (iii) support for the division of the North Pacific population into a central stock which feeds in Alaska and winters in Hawaii, and an eastern or 'American' stock which feeds along the coast of California and winters near Mexico; (iv) evidence of genetic heterogeneity within the Gulf of Maine feeding grounds and among the sampled feeding and breeding grounds of the western North Atlantic; and (v) support for the historical division between the Group IV (Western Australia) and Group V (eastern Australia, New Zealand and Tonga) stocks in the Southern Oceans. Overall, our results demonstrate a striking degree of genetic structure both within and between oceanic populations of humpback whales, despite the nearly unlimited migratory potential of this species. We suggest that the humpback whale is a suitable demographic and genetic model for the management of less tractable species of baleen whales and for the general study of gene flow among long-lived, mobile vertebrates in the marine ecosystem.

  9. Role of Halden Reactor Project for world-wide nuclear energy development

    Energy Technology Data Exchange (ETDEWEB)

    McGrath, M.A.; Volkov, B.

    2011-07-01

    The great interest for utilization of nuclear materials to produce energy in the middle of last century needed special investigations using first class research facilities. Common problems in the area of nuclear fuel development motivated the establishment of joint research efforts. The OECD Halden Reactor Project (HRP) is a good example of such a cooperative research effort, which has been performing for more than 50 years. During that time, the Halden Reactor evolved from a prototype heavy water reactor envisaged as a power source for different applications to a research reactor that is able to simulate in-core conditions of modern commercial power reactors. The adaptability of the Halden Reactor enables the HRP to be an important international test facility for nuclear fuels and materials development. The long-term international cooperation is based on the flexible HRP organizational structure which also provides the continued success. [1,2] This paper gives a brief history of the Halden Reactor Project and its contribution to world-wide nuclear energy development. Recent expansion of the Project to the East and Asian countries may also assist and stimulate the development of a nuclear industry within these countries. The achievements of the HRP rely on the versatility of the research carried out in the reactor with reliable testing techniques and in-pile instrumentation. Diversification of scientific activity in the areas of development of alternative energy resources and man-machine technology also provide the HRP with a stable position as one of the leaders in the world scientific community. All of these aspects are described in this paper together with current experimental works, including the investigation of ULBA (Kazakhstan) production fuel in comparison with other world fuel suppliers, as well as other future and prospective plans of the Project.(Author)

    Batchuluun Batpurev

    2007-06-01

    Full Text Available Two studies are reported, comparing the browser loading times of webpages created using common Web development techniques. The loading speeds were estimated in 12 Asian countries by members of the PANdora network, funded by the International Development Research Centre (IDRC to conduct collaborative research in the development of effective distance education (DE practices. An online survey tool with stopwatch-type counter was used. Responses were obtained from Bhutan, Cambodia, India, Indonesia, Laos, Mongolia, the Philippines, Sri Lanka, Pakistan, Singapore, Thailand, and Vietnam. In most of the survey conditions, browser loading times were noted up to four times slower than commonly prescribed as acceptable. Failure of pages to load at all was frequent. The speediest loading times were observed when the online material was hosted locally, and was created either in the Docebo learning management system (LMS, or in the HTML option provided by the Moodle LMS. It is recommended that formative evaluation of this type should become standard practice in the selection and use of online programming techniques, in order to preserve the accessibility of the World-Wide-Web across large geographical distances, as for DE in the developing world.

    2002-04-25

    The world wide web (WWW) has become a valuable source of 24 hour-a-day access to information needed by human health risk assessors. Various web sites and other Internet resources provide information needed for human hazard identification, dose-response evaluation, exposure assessment, risk characterization, and risk management. Information on risk communication is also available. Substantial collections of information on multiple aspects of risk assessment are found in sites sponsored by RiskWorld, the (US) EPA's National Center for Environmental Assessment (NCEA), the (US) National Library of Medicine's TOXNET, the (US) Agency for Toxic Substances and Disease Registry (ATSDR), and the International Programme on Chemical Safety (IPCS). Also valuable are various web sites providing information on the physical and chemical properties of chemicals, the environmental fate and transport of chemicals, government regulations, and guidance and training for performing risk assessments. Several professional societies and other organizations have web sites addressing risk assessment issues and information, and there are Internet mailing lists for online help and for sharing information and perspectives. We classify selected web sites according to user needs and provide the reader with a collection of selected sites that can serve as entry points to risk assessment-related web resources.

    A recent published model described the phenomenon of a global panic reaction (GPR) on the stock markets based on two remarkable stock market crashes in the months of January and March [Sperling W, Bleich S, Reulbach U, Black Monday on stock markets throughout the world - a new phenomenon of collective panic disorder? A psychiatric approach. Med Hypotheses; 2008]. This model was completed by a therapeutic approach following typical elements of cognitive behavioural therapy (CBT) [Sperling W, Biermann T, Maler JM, Global panic reaction - a therapeutic approach to a world-wide economic crisis. Med Hypotheses; 2009]. The phenomenon of a global panic reaction due to economic crises seems to have even larger implications on human health as well. It is well known that acute and chronic distress is competent to suppress the immune system by various mechanisms that are discussed in detail. This global panic reaction - that has also been observed in former times - might therefore be responsible for the new variation of recent influenza pandemic coming from Mexico.

    The Great World Wide Star Count is an international citizen science event encouraging everyone, astronomers and non-astronomers alike, to measure their local light pollution and report their observations online. This project is designed to raise awareness about light pollution as well as encourage learning in astronomy. Utilizing the international networking capabilities of Windows to the Universe, Star Count has engaged over 40,000 individuals from 64 countries and all 7 continents in its first five years. Data collection and online reporting is simple and user-friendly for citizen scientists of all ages. The collected data is available online in a variety of formats for use by students, teachers and scientists worldwide to assess how the quality of the night sky varies around the world. This session will share our results and demonstrate how students and scientists worldwide can explore and analyze the results from the first five years of the project. We will discuss how our team planned and executed the project in such a way that non-astronomers were able to make valid and useful contributions.

    Watson, Val; Chancellor, Marisa K. (Technical Monitor)

    1996-01-01

    Two new technologies, the FASTexpedition and Remote FAST, have been developed that provide remote, 3D (three dimensional), high resolution, dynamic, interactive viewing of scientific data. The FASTexpedition permits one to access scientific data from the World Wide Web, take guided expeditions through the data, and continue with self controlled expeditions through the data. Remote FAST permits collaborators at remote sites to simultaneously view an analysis of scientific data being controlled by one of the collaborators. Control can be transferred between sites. These technologies are now being used for remote collaboration in joint university, industry, and NASA projects. Also, NASA Ames Research Center has initiated a project to make scientific data and guided expeditions through the data available as FASTexpeditions on the World Wide Web for educational purposes. Previously, remote visualization of dynamic data was done using video format (transmitting pixel information) such as video conferencing or MPEG (Motion Picture Expert Group) movies on the Internet. The concept for this new technology is to send the raw data (e.g., grids, vectors, and scalars) along with viewing scripts over the Internet and have the pixels generated by a visualization tool running on the viewers local workstation. The visualization tool that is currently used is FAST (Flow Analysis Software Toolkit). The advantages of this new technology over using video format are: (1) The visual is much higher in resolution (1280x1024 pixels with 24 bits of color) than typical video format transmitted over the network. (2) The form of the visualization can be controlled interactively (because the viewer is interactively controlling the visualization tool running on his workstation). (3) A rich variety of guided expeditions through the data can be included easily. (4) A capability is provided for other sites to see a visual analysis of one site as the analysis is interactively performed. Control of

    We report results from an NSF-funded project to build, test, and research the impact of a WorldWide Telescope Visualization Lab (WWT Vizlab), meant to offer learners a deeper physical understanding of the causes of the Moon’s phases and eclipses. The Moon Phases VizLab is designed to promote accurate visualization of the complex, 3-dimensional Earth-Sun-Moon relationships required to understand the Moon’s phases, while also providing opportunities for middle school students to practice critical science skills, like using models, making predictions and observations, and linking them in evidence-based explanations. In the Moon Phases VizLab, students use both computer-based models and lamp + ball physical models. The VizLab emphasizes the use of different scales in models, why some models are to scale and some are not, and how choices we make in a model can sometimes inadvertently lead to misconceptions. For example, textbook images almost always depict the Earth and Moon as being vastly too close together, and this contributes to the common misconception that the Moon’s phases are caused by the Earth’s shadow. We tested the Moon Phases VizLab in two separate phases. In Phase 1 (fall 2012), we compared learning gains from the WorldWide Telescope (WWT) VizLab with a traditional 2-dimensional Moon phases simulator. Students in this study who used WWT had overall higher learning gains than students who used the traditional 2D simulator, and demonstrated greater enthusiasm for using the virtual model than students who used the 2D simulator. In Phase 2 (spring 2013), all students in the study used WWT for the virtual model, but we experimented with different sequencing of physical and virtual models in the classroom. We found that students who began the unit with higher prior knowledge of Moon phases (based on the pre-unit assessment) had overall higher learning gains when they used the virtual model first, followed by the physical model, while students who had

    1994-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of the WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology Opportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. During its first year on the Web, LaRC also developed several WWW-based information repositories. The Langley Technical Report Server (LTRS), a technical paper delivery system with integrated searching and retrieval, has proved to be quite popular. The NASA Technical Report Server (NTRS), an outgrowth of LTRS, provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software with the possible phase-out of NASA's COSMIC program. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people. With the completion of the LaRC reorganization, the Technology Applications Group, charged with interfacing with non-aerospace companies, opened for business with a popular home page.

    New, visually rich, astronomical software environments coupled with large web-accessible data sets hold the promise of new and exciting ways to teach, collaborate, and explore the universe. These freeware tools provide contextual views of astronomical objects, real time access to multi-wavelength sky surveys, and, most importantly, the ability to incorporate new data and to produce user created content. This interactive panel examined the capabilities of Google Sky and WorldWide Telescope, and explored case studies of how these tools have been used to create compelling and participatory educational experiences in both formal (i.e., K-12 and undergraduate non-science majors classrooms), and informal (e.g., museum) settings. The overall goal of this session was to stimulate a discussion about future uses of these technologies. Substantial time was allotted for participants to create conceptual designs of learning experiences for use at their home institutions, with feedback provided by the panel members. Activities included technical discussions (e.g., mechanisms for incorporating new data and dissemination tools), exercises in narrative preparation, and a brainstorming session to identify potential future uses of these technologies.

    Compact optical discs (CDs and the World Wide Web (the Web are two mechanisms that contemporary libraries extensively use for digitized information storage, dissemination, and retrieval. The Web features an unparalleled global accessibility free from many previously known temporal and spatial restrictions. Its real-time update capability is impossible for CDs. Web-based information delivery can reduce the cost in hardware and software ownership and management of a local library, and provide one-to-one zcustomization to better serve library's clients. The current limitations of the Web include inadequate speed in data transmission, particularly for multimedia applications, and its insufficient reliability, search capabilities, and security. In comparison, speed, quality, portability, and reliability are the current advantages of CDs over the Web. These features, together with the trend in the PC industry and market, suggest that CDs will exist and continue to develop. CD/Web hybrids can combine the best of both developing mechanisms and offer optimal results. Through a comparison of CDs and the Web, it is argued that the functionality and unique features of a technology determine its future.

    Information on mutations in human hemoglobin is important in many efforts, including understanding the pathophysiology of hemoglobin diseases, developing therapies, elucidating the dynamics of sequence alterations inhuman populations, and dissecting the details of protein structure/function relationships. Currently, information is available on a large number of mutations and variants, but is distributed among thousands of papers. In an effort to organize this voluminous data set, two Syllabi have been prepared compiling succinct information on human hemoglobin abnormalities. In both of these, each entry provides amino acid and/or DNA sequence alterations, hematological and clinical data, methodology used for characterization, ethnic distribution, and functional properties and stability of the hemoglobin, together with appropriate literature references. A Syllabus of Human Hemoglobin Variants (1996) describes 693 abnormal hemoglobins resulting from alterations in the alpha-, beta-, gamma-, and delta-globin chains, including special abnormalities such as double mutations, hybrid chains, elongated chains, deletions, and insertions. We have converted this resource to an electronic form that is accessible via the World Wide Web at the Globin Gene Server (http://globin.cse.psu.edu). Hyperlinks are provided from each entry in the tables of variants to the corresponding full description. In addition, a simple query interface allows the user to find all entries containing a designated word or phrase. We are in the process of converting A Syllabus of Thalassemia Mutations (1997) to a similar electronic format.

    The Department of Energy - Office of Special Projects and Argonne National Laboratory (ANL), along with the Department of Energy - office of Scientific and Technical Information have previously designed and implemented the Environment, Safety and Health Facility Profile Information Management System (FPIMS) to facilitate greater efficiency in searching, analyzing and disseminating information found within environment, safety and health oversight documents. This information retrieval based system serves as a central repository for full-text electronic oversight documents, as well as a management planning and decision making tool that can assist in trend and root cause analyses. Continuous improvement of environment, safety and health programs are currently aided through this personal computer-based system by providing a means for the open communication of lessons learned across the department. Overall benefits have included reductions in costs and improvements in past information management capabilities. Access to the FPIMS has been possible historically through a headquarters-based local area network equipped with modems. Continued demand for greater accessibility of the system by remote DOE field offices and sites, in conjunction with the Secretary of Energy` s call for greater public accessibility to Department of Energy (DOE) information resources, has been the impetus to expand access through the use of Internet technologies. Therefore, the following paper will discuss reasons for migrating the FPIMS system into the World Wide Web (Web), various lessons learned from the FPIMS migration effort, as well as future plans for enhancing the Web-based FPIMS.

    The `conjunction fallacy' has been extensively debated by scholars in cognitive science and, in recent times, the discussion has been enriched by the proposal of modeling the fallacy using the quantum formalism. Two major quantum approaches have been put forward: the first assumes that respondents use a two-step sequential reasoning and that the fallacy results from the presence of `question order effects'; the second assumes that respondents evaluate the cognitive situation as a whole and that the fallacy results from the `emergence of new meanings', as an `effect of overextension' in the conceptual conjunction. Thus, the question arises as to determine whether and to what extent conjunction fallacies would result from `order effects' or, instead, from `emergence effects'. To help clarify this situation, we propose to use the World Wide Web as an `information space' that can be interrogated both in a sequential and non-sequential way, to test these two quantum approaches. We find that `emergence effects', and not `order effects', should be considered the main cognitive mechanism producing the observed conjunction fallacies.

    Satellite data summary images and analysis plots from the Tropical Ocean Global Atmosphere Coupled Ocean-Atmosphere Response Experiment (TOGA COARE), which were initially prepared in the field at the Honiara Operations Center, are now available on the Internet via World Wide Web browsers such as Mosaic. These satellite data summaries consist of products derived from the Japanese Geosynchronous Meteorological Satellite IR data: a time-size series of the distribution of contiguous cold cloudiness areas, weekly percent high cloudiness (PHC) maps, and a five-month time-longitudinal diagram illustrating the zonal motion of large areas of cold cloudiness. The weekly PHC maps are overlaid with weekly mean 850-hPa wind calculated from the European Centre for Medium-Range Weather Forecasts (ECMWF) global analysis field and can be viewed as an animation loop. These satellite summaries provide an overview of spatial and temporal variabilities of the cloud population and a large-scale context for studies concerning specific processes of various components of TOGA COARE.

    In response to a 1995 NASA SPDS announcement of support for preservation and distribution of important data sets online, the Geophysical Institute, University of Alaska Fairbanks, Alaska, proposed to provide World Wide Web access to the Poker Flat Auroral All-sky Camera images in real time. The Poker auroral all-sky camera is located in the Davis Science Operation Center at Poker Flat Rocket Range about 30 miles north-east of Fairbanks, Alaska, and is connected, through a microwave link, with the Geophysical Institute where we maintain the data base linked to the Web. To protect the low light-level all-sky TV camera from damage due to excessive light, we only operate during the winter season when the moon is down. The camera and data acquisition is now fully computer controlled. Digital images are transmitted each minute to the Web linked data base where the data are available in a number of different presentations: (1) Individual JPEG compressed images (1 minute resolution); (2) Time lapse MPEG movie of the stored images; and (3) A meridional plot of the entire night activity.

    In order for humans and electronics to fully and safely operate in the space environment, codes like HZETRN (High Charge and Energy Transport) must be included in any designer's toolbox for design evaluation with respect to radiation damage. Currently, spacecraft designers do not have easy access to accurate radiation codes like HZETRN to evaluate their design for radiation effects on humans and electronics. Today, the World Wide Web is sophisticated enough to support the entire HZETRN code and all of the associated pre and post processing tools. This package is called SIREST (Space Ionizing Radiation Effects and Shielding Tools). There are many advantages to SIREST. The most important advantage is the instant update capability of the web. Another major advantage is the modularity that the web imposes on the code. Right now, the major disadvantage of SIREST will be its modularity inside the designer's system. This mostly comes from the fact that a consistent interface between the designer and the computer system to evaluate the design is incomplete. This, however, is to be solved in the Intelligent Synthesis Environment (ISE) program currently being funded by NASA.

    The World Wide Web has provided the public with easy and affordable access to a vast range of information. However, claims may be unsubstantiated and misleading. The purpose of this study was to use cutaneous laser surgery as a model to assess the availability and reliability of Web sites and to evaluate this resource for the quality of patient and provider education. Three commercial methods of searching the Internet were used, identifying nearly 500,000 possible sites. The first 100 sites listed by each search engine (a total of 300 sites) were compared. Of these, 126 were listed repeatedly within a given retrieval method, whereas only 3 sites were identified by all 3 search engines. After elimination of duplicates, 40 sites were evaluated for content and currency of information. The most common features included postoperative care suggestions, options for pain management or anesthesia, a description of the way in which lasers work, and the types of lasers used for different procedures. Potential contraindications to laser procedures were described on fewer than 30% of the sites reviewed. None of the sites contained substantiation of claims or referrals to peer-reviewed publications or research. Because of duplication and the prioritization systems of search engines, the ease of finding sites did not correlate with the quality of the site's content. Our findings show that advertisements for services exceed useful information.

    The Boyd E. Christenberry Planetarium at Samford University (Birmingham, AL) offers family friendly, live, and interactive planetarium presentations that educate the public on topics from astronomy basics to current cutting edge astronomical discoveries. With limited funding, it is not possible to provide state of the art planetarium hardware for these community audiences. In a society in which many people, even young children, have access to high resolution smart phones and highly realistic video games, it is important to leverage cutting-edge technology to intrigue young and old minds alike. We use an Oculus Rift virtual reality headset running AAS WorldWide Telescope software to visualize 3D data in a fully immersive environment. We create interactive experiences and videos to highlight astronomical concepts and also to communicate the beauty of our universe. The ease of portability enables us to set up at Virtual Reality (VR) experience at various events, festivals, and even in classrooms to provide a community outreach that a fixed planetarium cannot. This VR experience adds the “wow” factor that encourages children and adults to engage in our various planetarium events to learn more about astronomy and continue to explore the final frontier of space. These VR experiences encourages our college students to participate in our astronomy education resulting in increased interest in STEM fields, particularly physics and math.

    Internet use has increased greatly in the past decade across all demographic sectors in the United States, and the World Wide Web currently serves as a valuable informational resource for physicians. A study was conducted in 2005 to evaluate the role of the Web in radiology education. A 28-question multiple-choice survey was administered during two institutionally run continuing medical education (CME) conferences. Questions addressed perceptions and use of the Web, as well as preferred resources for radiologic information and radiology education. Surveys were submitted by 92 radiologists, 97% of whom use the Web for radiology education. The reliability of information on the Web was deemed equal to that of information from traditional sources by 69% of respondents. Forty-five percent use the Web for CME; however, an institutionally run course was selected most frequently as the preferred method of CME, as well as the most effective and efficient. The search engine used by the largest number of participants to identify radiologic information is Google. For reading journal articles, 67% of respondents prefer hard copy. Monthly review of publications made available online before the print version is performed by only 26%. The results of the survey indicate that, despite an increase in Internet use and the perception that Web-based information is reliable, most practicing radiologists still prefer traditional educational resources for radiologic information and radiology education.

    Full Text Available The primary goal of this paper is to investigate various elements of websites and compare the quality of two groups of university website designs. The procedure for the quality assessment of website design involves various modules: Extracting components of websites, validating web pages, and identifying broken links. It continues with collecting the compared data of the existing statement of Iranian and British universities websites. The 5-point scale has been chosen as evaluator tool. Different kinds of tools are used to examine above components. These tools include: World Wide Web Consortium (W3C Link Checker, W3C markup validation service, web page analyzer, and website extractor. The W3C statistics findings show that Iranians university websites have high rate of errors compared with British university websites. These errors had been occurred in various levels of the websites: For example, HTML errors, broken links, server connectivity, image load error, and so on. It is clear that some of the websites donot followthe explicit website designing standards like W3Cs standards, and use nonprofessional designers whichcauseescalating the rate of website′s errors.

    Muenkelt, Olaf; Kaufmann, Oliver; Eckstein, Wolfgang

    1997-01-01

    This article propose a way to automatically retrieve images from the world-wide-web using a semantic description for images and an agent concept for the retrieval of images. The system represents image in a textual way, e.g. look for a portrait of the a specific person, or fetch an image showing a countryside in Southern California. This textual descriptions are fed in search machines, e.g. yahoo, alta- vista. The resulting html documents are seeked for links. The next step subsequently processes each link by fetching the document other the net, converting it to an ascii representation, and performing a full text search by using the image description. This leads to starting points of images which are retrieved via a web-agent. The image descriptions are decomposed in a set of parts containing image operations which are further processed, e.g. a set for representing the background of a portrait tries to find a homogeneous region in the image because this is likely to find in a portrait. Additional operations are performed on the foreground, i.e. the image region which contains e.g. the face of a person. The system is realized using two C++ libraries: one for building up web-agents, LIWA++, and one for processing images, HORUS.

    Full Text Available In the past decade, the use of the World Wide Web (WWW as a tool for job-seeking and recruitment has increased globally, changing the dynamics for job-seekers and recruitment organisations. The purpose of this study was to gain greater insight into the factors that influence the adoption of the Internet (WWW for job-seeking within a South African context. The impact of the Internet (WWW and newspaper-reading habits on the adoption process was of specific interest. Data was gathered by survey through telephonic interviews with 228 job seekers applying for information technology (IT work in Cape Town, South Africa. The findings show that the income of a job-seeker influences the favourability of internet facilitating conditions they encounter. Facilitating conditions in turn influence Internet (WWW usage habits. Such habits influence performance expectancy, effort expectancy and intentions to use the Internet (WWW for job-seeking. The actual extent of Internet (WWW usage for job-seeking is positively influenced by these usage intentions and negatively influenced by newspaper-reading habits. These and other findings are discussed and implications drawn.

    2015-01-01

    A principal tenant of the scientific method is that experiments must be repeatable and relies on ceteris paribus (i.e., all other things being equal). As a scientific community, involved in data sciences, we must investigate ways to establish an environment where experiments can be repeated. We can no longer allude to where the data comes from, we must add rigor to the data collection and management process from which our analysis is conducted. This paper describes a computing environment to support repeatable scientific big data experimentation of world-wide scientific literature, and recommends a system that is housed at the Oak Ridge National Laboratory in order to provide value to investigators from government agencies, academic institutions, and industry entities. The described computing environment also adheres to the recently instituted digital data management plan mandated by multiple US government agencies, which involves all stages of the digital data life cycle including capture, analysis, sharing, and preservation. It particularly focuses on the sharing and preservation of digital research data. The details of this computing environment are explained within the context of cloud services by the three layer classification of Software as a Service , Platform as a Service , and Infrastructure as a Service .

  16. ETDEWEB versus the World-Wide-Web: a specific database/web comparison

    2010-06-28

    A study was performed comparing user search results from the specialized scientific database on energy-related information, ETDEWEB, with search results from the internet search engines Google and Google Scholar. The primary objective of the study was to determine if ETDEWEB (the Energy Technology Data Exchange – World Energy Base) continues to bring the user search results that are not being found by Google and Google Scholar. As a multilateral information exchange initiative, ETDE’s member countries and partners contribute cost- and task-sharing resources to build the largest database of energy-related information in the world. As of early 2010, the ETDEWEB database has 4.3 million citations to world-wide energy literature. One of ETDEWEB’s strengths is its focused scientific content and direct access to full text for its grey literature (over 300,000 documents in PDF available for viewing from the ETDE site and over a million additional links to where the documents can be found at research organizations and major publishers globally). Google and Google Scholar are well-known for the wide breadth of the information they search, with Google bringing in news, factual and opinion-related information, and Google Scholar also emphasizing scientific content across many disciplines. The analysis compared the results of 15 energy-related queries performed on all three systems using identical words/phrases. A variety of subjects was chosen, although the topics were mostly in renewable energy areas due to broad international interest. Over 40,000 search result records from the three sources were evaluated. The study concluded that ETDEWEB is a significant resource to energy experts for discovering relevant energy information. For the 15 topics in this study, ETDEWEB was shown to bring the user unique results not shown by Google or Google Scholar 86.7% of the time. Much was learned from the study beyond just metric comparisons. Observations about the strengths of each

    Following the success of the first Worldwide Energy Efficiency Benchmark (WEEB) in the brewing Industry in 2000 using the data from 1999, a second WEEB was set up in 2004 using the data from 2003. The results of the energy benchmark 2003 are presented in this report. The Dutch and Belgium brewers commissioned the study and a consortium of KWA Business Consultants (Amersfoort, The Netherlands) and Brewing Research International (Surrey, UK) performed a world-wide benchmarking study on energy efficiency in the brewing industry. 158 breweries from all over the world, representing 26% of the world's beer production, took part in this project (all with an output of at least 0.5 million hectolitres beer per year). This report consists out of two parts: a description of the methodology, used for benchmarking the energy efficiency in the brewing industry; and the results of the benchmark in world wide figures.

    The quick ascendance of the World Wide Web as the dominant vehicle for internet communication has recently made experimentation in a multimedia environment feasible on the Internet. Although web sites containing online psychology demonstrations and experiments for non-handicapped individuals have appeared in recent years (especially in the areas of cognitive and social psychology), there appear to have been few attempts to conduct online experimentation with special populations. We recently completed two online pilot studies of families with Down syndrome or Williams syndrome members: a) A survey that asks (via Likert rating scales, adjective checklists, multiple-choice style questions, and text-entry boxes) about family background, computer use, and temperament of the special needs family member; and b) An experiment (completed by an individual with special needs) that includes auditory and visual digit span tasks and a memory-for-orientation task in which responses are entered via mouse clicks. Recruiting began with e-mail announcements to representative Down syndrome and Williams syndrome discussion groups, listserves, and bulletin boards, and submission of the project's URL (http://www.cofc.edu/~marcellm/testaw.htm) and key indexing terms to selected search engines. This paper reviews technical aspects of developing the online programmes as well as the strengths and weaknesses of online vs. traditional laboratory-based research in relation to issues such as experimental control, delivery of instructions, experimenter bias, participant recruitment, sample heterogeneity, generalization, attrition, privacy, financial costs, data integrity, and ethics. We conclude by offering our thoughts on two ways of implementing online experimentation with special populations: a) Using a remote parent 'helper' as a proxy to work with the target individual; and b) Collaborating with professional colleagues in Web-based projects conducted in traditional laboratory settings.

    Both global area coverage (GAC) and high-resolution picture transmission (HRTP) data from the Advanced Very High Resolution Radiometer (AVHRR) are made available to laternet users through an online data access system. Older GOES-7 data am also available. Created as a "testbed" data system for NASA's future Earth Observing System Data and Information System (EOSDIS), this testbed provides an opportunity to test both the technical requirements of an onune'd;ta system and the different ways in which the -general user, community would employ such a system. Initiated in December 1991, the basic data system experienced five major evolutionary changes In response to user requests and requirements. Features added with these changes were the addition of online browse, user subsetting, dynamic image Processing/navigation, a stand-alone data storage system, and movement,from an X-windows graphical user Interface (GUI) to a World Wide Web (WWW) interface. Over Its lifetime, the system has had as many as 2500 registered users. The system on the WWW has had over 2500 hits since October 1995. Many of these hits are by casual users that only take the GIF images directly from the interface screens and do not specifically order digital data. Still, there b a consistent stream of users ordering the navigated image data and related products (maps and so forth). We have recently added a real-time, seven- day, northwestern United States normalized difference vegetation index (NDVI) composite that has generated considerable Interest.

  20. Global Cooling: Increasing World-Wide Urban Albedos to Offset CO2

    Energy Technology Data Exchange (ETDEWEB)

    Akbari, Hashem; Menon, Surabi; Rosenfeld, Arthur

    2008-01-14

    Modification of urban albedos reduces summertime urban temperatures, resulting in a better urban air quality and building air-conditioning savings. Furthermore, increasing urban albedos has the added benefit of reflecting some of the incoming global solar radiation and countering to some extent the effects of global warming. In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). Using reflective materials, both roof and the pavement albedos can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60% (a U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills). On a global basis, our preliminary estimate is that increasing the world-wide albedos of urban roofs and paved surfaces will induce a negative radiative forcing on the earth equivalent to removing {approx} 22-40 Gt of CO{sub 2} from the atmosphere. Since, 55% of the emitted CO{sub 2} remains in the atmosphere, removal of 22-40 Gt of CO{sub 2} from the atmosphere is equivalent to reducing global CO{sub 2} emissions by 40-73 Gt. At {approx} $25/tonne of CO{sub 2}, a 40-73 Gt CO{sub 2} emission reduction from changing the albedo of roofs and paved surfaces is worth about $1,000B to 1800B. These estimated savings are dependent on assumptions used in this study, but nevertheless demonstrate considerable benefits that may be obtained from cooler roofs and pavements.

    1998-01-01

    NASA's New Millenium Program (NMP) has identified a variety of revolutionary technologies that will support orders of magnitude improvements in the capabilities of spacecraft missions. This program's Autonomy team has focused on science and engineering automation technologies. In doing so, it has established a clear development roadmap specifying the experiments and demonstrations required to mature these technologies. The primary developmental thrusts of this roadmap are in the areas of remote agents, PI/operator interface, planning/scheduling fault management, and smart execution architectures. Phases 1 and 2 of the ASSET Project (previously known as the WebSat project) have focused on establishing World Wide Web-based commanding and telemetry services as an advanced means of interfacing a spacecraft system with the PI and operators. Current automated capabilities include Web-based command submission, limited contact scheduling, command list generation and transfer to the ground station, spacecraft support for demonstrations experiments, data transfer from the ground station back to the ASSET system, data archiving, and Web-based telemetry distribution. Phase 2 was finished in December 1996. During January-December 1997 work was commenced on Phase 3 of the ASSET Project. Phase 3 is the subject of this report. This phase permitted SSDL and its project partners to expand the ASSET system in a variety of ways. These added capabilities included the advancement of ground station capabilities, the adaptation of spacecraft on-board software, and the expansion of capabilities of the ASSET management algorithms. Specific goals of Phase 3 were: (1) Extend Web-based goal-level commanding for both the payload PI and the spacecraft engineer; (2) Support prioritized handling of multiple PIs as well as associated payload experimenters; (3) Expand the number and types of experiments supported by the ASSET system and its associated spacecraft; (4) Implement more advanced resource

    1998-01-01

    There is a great deal of excitement about using the internet and the World Wide Web in education. There are such exciting possibilities and there is a wealth and variety of material up on the web. There are however many problems, problems of access and resources, problems of quality -- for every excellent resource there are many poor ones, and there are insufficiently explored problems of teacher training and motivation. For example, Wiesenmayer and Meadows report on a study of 347 West Virginia science teachers. These teachers were enrolled in a week-long summer workshop to introduce them to the internet and its educational potential. The teachers were asked to review science sites as to overall quality and then about their usefulness in their own classrooms. The teachers were enthusiastic about the web, and gave two-thirds of the sites high ratings, and essentially all the rest average ratings. But alarmingly, over 80% of these sites were viewed as having no direct applicability in the teacher's own classroom. This summer I was assigned to work on the Amphion project in the Automated Software Engineering Group under the leadership of Michael Lowry. I wished to find educational applications of the Amphion system, which in its current implementation can be used to create fortran programs and animations using the SPICE libraries created by the NAIF group at JPL. I wished to find an application which provided real added educational value, which was in line with educational curriculum standards and which would serve a documented need of the educational community. The application selected was teaching about the causes of the seasons -- at the approximately the fourth, fifth, sixth grade level. This topic was chosen because it is in line with national curriculum standards. The fourth, fifth, sixth grade level was selected to coincide with the grade level served by the Ames Aerospace Encounter, which services 10,000 children a year on field trips. The hope is that

  3. Obtaining Streamflow Statistics for Massachusetts Streams on the World Wide Web

    2000-01-01

    A World Wide Web application has been developed to make it easy to obtain streamflow statistics for user-selected locations on Massachusetts streams. The Web application, named STREAMSTATS (available at http://water.usgs.gov/osw/streamstats/massachusetts.html ), can provide peak-flow frequency, low-flow frequency, and flow-duration statistics for most streams in Massachusetts. These statistics describe the magnitude (how much), frequency (how often), and duration (how long) of flow in a stream. The U.S. Geological Survey (USGS) has published streamflow statistics, such as the 100-year peak flow, the 7-day, 10-year low flow, and flow-duration statistics, for its data-collection stations in numerous reports. Federal, State, and local agencies need these statistics to plan and manage use of water resources and to regulate activities in and around streams. Engineering and environmental consulting firms, utilities, industry, and others use the statistics to design and operate water-supply systems, hydropower facilities, industrial facilities, wastewater treatment facilities, and roads, bridges, and other structures. Until now, streamflow statistics for data-collection stations have often been difficult to obtain because they are scattered among many reports, some of which are not readily available to the public. In addition, streamflow statistics are often needed for locations where no data are available. STREAMSTATS helps solve these problems. STREAMSTATS was developed jointly by the USGS and MassGIS, the State Geographic Information Systems (GIS) agency, in cooperation with the Massachusetts Departments of Environmental Management and Environmental Protection. The application consists of three major components: (1) a user interface that displays maps and allows users to select stream locations for which they want streamflow statistics (fig. 1), (2) a data base of previously published streamflow statistics and descriptive information for 725 USGS data

    signals is a fundamental advantage of isotopomer ratios (Augusti et al., Chem. Geol 2008). These results demonstrate that increasing [CO2] has reduced the ratio of photorespiration to photosynthesis on a global scale. Photorespiration is a side reaction that decreases the C gain of plants; the suppression of photorespiration in all analyzed trees indicates that increasing atmospheric [CO2] is enhancing the photosynthetic efficiency of trees world-wide. The consensus response of the trees agrees with the response of annual plants in greenhouse experiments, with three important conclusions. First, the generality of the isotopomer shift confirms that the CO2 response reflects the ratio of photosynthesis to photorespiration, and that it creates a robust signal in tree rings. Second, the agreement between greenhouse-grown plants and trees indicates that there has not been an acclimation response of the trees during the past centuries. Third, the results show that the regulation of tree gas exchange has during past centuries been governed by the same rules as observed in manipulative experiments, in contradiction to recent reports (Keenan et al., Nature 2013).

    A gap-free, world-wide, ocean-, atmosphere-, and land surface-spanning geophysical data-set of three decades time-duration containing the full set of geophysical parameters characterizing global weather is the scientific perquisite for defining the climate; the generally-accepted definition in the meteorological community is that climate is the 30-year running-average of weather. Until such a tridecadal climate baseline exists, climate change discussions inevitably will have a semi-speculative, vs. a purely scientific, character, as the baseline against which changes are referenced will at least somewhat uncertain.

Since the network resou rces are expensive, so IG is a resource-bounded task. The main purpose of this paper is to find an efficient gathering method for specific topic. This paper pr esents methods for predicting page's content without downloading it, designs dif ferent controlling strategies, and defines several kinds of page downloading pri ority measures. An IG system, TH-Gatherer, was built to test the methods, and d ifferent experiments were carried out. Through experiments, it was found that th e content of candidate pages can be predicted approximately without downloading. When the priority based gathering strategy and hybrid measure are used, the gat hering efficiency is four times of that of BFS strategy which is used by many cu rrent IG tools (including crawlers and off-line browsing tools).

    During the 227th American Astronomical Society meeting last week in Kissimmee, the AAS announced the exciting news that it will become the new institutional home of Microsofts WorldWide Telescope (WWT) astronomy software.WWT is a scriptable and interactive way of browsing the multi-wavelength sky as it is seen from Earth, and the universe as we would travel within it. WWT can be run either as a desktop app or from within an internet browser. And of interest to researchers especially its an incredibly useful way to visualize and contextualize astronomical data.What does WWTs transition to the AAS as its new host mean? WWT was open-sourced by Microsoft Research last year, and hosting by the AAS will permit broad community involvement in the form of contribution of both code and guidance in WWTs further development.All of this begs the question: why might YOU want to use WWT? That depends on whether your goal is to use it for research, education, or just for fun.WWT for ResearchIfyou thought WWT was just for education and outreach, think again! Here are just a few things you can do with WWT to advance your astronomical research1:1) Put surveys into context, on top of more than 40 different all-sky images, spanning the electromagnetic spectrum.2) Perform literature searches from the sky.3) Compare images and catalogs at different wavelengths, on-the-fly in seconds.4) Show your own online data to the world, in an API that allows users to see it on the sky in their browsers.5) Communicate to colleagues and learners about the sky using interactive tours of your data and ideas.An example of WWT used to perform astronomy research is the recently highlighted work on the bones of the Milky Way, in which the authors used WWT to overlay multiple data sets and visually identify and then search for infrared dark clouds along the predicted positions of Milky Way spiral arms.An example of WWT used to communicate research is given in this paper, wherein a link in the caption of a

  2. Use of the World Wide Web in Lower-Division Chemistry Courses

    Science.gov (United States)

    Stevens, Karen E.; Stevens, Richard E.

    1996-10-01

    Recent articles have identified the plethora of chemical information existing currently on the World-Wide Web (WWW) available via the Internet (1). This information medium is particularly valuable because it represents a very up-to-date source of information. Site managers can update information and it can be "instantaneously visited" by someone. As an example, several current topics of chemical significance were highlighted in a nonmajor chemistry class held in January 1996 at our college. December 31, 1995, represented the last day that leaded gasoline could be sold for use in automobiles. In early January, the FDA approved the synthetic fat olestra for use in snack foods. Both of these topics provoked great interest in students as they brought up issues of relevance and interest to their lives that were currently being discussed in the news. The WWW was utilized extensively as a source of information and current updates. Print media, such as texts and reference manuals, have a much longer "lag-time" before current information can be typeset, printed, and accessed by a researcher. Previous articles (1, 2) have focused on Internet use for upper-division classes, but we have found a useful way to bring the Internet into nonmajor and freshman level classes composed of 20-50 students. The student assignment was to find information on a chemical topic currently in the news by using the WWW and use that information to write a 2-3 page essay (3, 4). Using the Internet to find information presents one issue not previously encountered when using encyclopedias, reference books, or textbooks, but an issue raised in previous editorials in this Journal (5, 6). That difference is that virtually anyone can post information on the WWW. Thus, the WWW can have governmental organizations, environmental groups, large corporations, or just individuals posting their views. Hence, when searching a particular topic, students might find a very factual article, or they might find a very

  8. Singapore National Medical Image Resource Centre (SN.MIRC): a world wide web resource for radiology education.

    Yang, Guo-Liang; Lim, C C Tchoyoson

    2006-08-01

    Radiology education is heavily dependent on visual images, and case-based teaching files comprising medical images can be an important tool for teaching diagnostic radiology. Currently, hardcopy film is being rapidly replaced by digital radiological images in teaching hospitals, and an electronic teaching file (ETF) library would be desirable. Furthermore, a repository of ETFs deployed on the World Wide Web has the potential for e-learning applications to benefit a larger community of learners. In this paper, we describe a Singapore National Medical Image Resource Centre (SN.MIRC) that can serve as a World Wide Web resource for teaching diagnostic radiology. On SN.MIRC, ETFs can be created using a variety of mechanisms including file upload and online form-filling, and users can search for cases using the Medical Image Resource Center (MIRC) query schema developed by the Radiological Society of North America (RSNA). The system can be improved with future enhancements, including multimedia interactive teaching files and distance learning for continuing professional development. However, significant challenges exist when exploring the potential of using the World Wide Web for radiology education.

    The World Wide Web-based form is a promising method for the construction of an on-line data collection system for clinical and epidemiological research. It is, however, laborious to prepare a common gateway interface (CGI) program for each project, which the World Wide Web server needs to handle the submitted data. In medicine, it is even more laborious because the CGI program must check deficits, type, ranges, and logical errors (bad combination of data) of entered data for quality assurance as well as data length and meta-characters of the entered data to enhance the security of the server. We have extended the specification of the hypertext markup language (HTML) form to accommodate information necessary for such data checking and we have developed software named AUTOFORM for this purpose. The software automatically analyzes the extended HTML form and generates the corresponding ordinary HTML form, 'Makefile', and C source of CGI programs. The resultant CGI program checks the entered data through the HTML form, records them in a computer, and returns them to the end-user. AUTOFORM drastically reduces the burden of development of the World Wide Web-based data entry system and allows the CGI programs to be more securely and reliably prepared than had they been written from scratch.

  14. The global inventor gap: distribution and equality of world-wide inventive effort, 1990-2010.

    Directory of Open Access Journals (Sweden)

    Hannes Toivanen

    Full Text Available Applying distance-to-frontier analysis, we have used 2.9 million patents and population data to assess whether the relative capacity of world countries and major regions to create new knowledge and technology has become globally more equal or less equal between 1990 and 2010. We show with the Gini coefficient that the global distribution of inventors has become more equal between major countries and regions. However, this trend has been largely due to the improved performance of only two major countries, China and India. The worst performing regions, totalling a population of almost 2 billion, are actually falling behind. Our results suggest that substantial parts of the global population have fallen further behind countries at the global frontier in their ability to create new knowledge and inventions, and that the catch-up among the least developed and middle-income countries is highly uneven, prompting questions about the nature and future of the global knowledge economy.

Everyone on Earth is invited to join the celebration by hosting or attending an InOMN event - and uniting on one day each year to look at and learn about the Moon together. This year marks the seventh year of InOMN, which will be held on October 8, 2016. Between 2010 and 2015, a total of 3,275 events were registered worldwide, 49% of which were held in the United States. In 2015, a total of 545 events were registered on the InOMN website from around the world. These events were scheduled to be held in 54 different countries, 43% of which were registered in the United States from 40 states and the District of Columbia. InOMN events are hosted by a variety of institutions including astronomy clubs, observatories, schools, and universities and hosted at a variety of public and private institutions all over the world including museums, planetaria, schools, universities, observatories, parks, and private businesses and private homes. Evaluation of InOMN is led by the Planetary Science Institute who assesses the success of InOMN through analysis of event registrations, facilitator surveys, and visitor survey. Current InOMN efforts demonstrate success in meeting the overall goals of the LRO E/PO goals including raising visitors' awareness of lunar science and exploration, providing audiences with information about lunar science and exploration along with access to LRO data and science results, and inspiring visitors to want to learn more about the Moon and providing connections to opportunities to do so. InOMN is sponsored by NASA's Lunar Reconnaissance Orbiter, NASA's Solar System Exploration Research Virtual Institute (SSERVI), and the Lunar and Planetary Institute.

    2011-01-01

    The extraordinary progress in the knowledge of infectious disease, the discovery of antibiotics and effective vaccines are among the great achievement of the nineteenth and twentieth centuries. These achievement have led to a dramatic reduction in the levels of mortality from these diseases. According to the World Health Organization, the term "re-emerging infectious diseases" refers to infectious diseases, which although well known, have not been of recent public health importance. However, climate change, migration, changes in health services, antibiotic resistance, population increase, international travel, the increase in the number of immune-depressed patients ,etc have lead to the re-emergence of these diseases. The climate changes are exposing sectors of the population to inadequate fresh air, water, food and resources for survival which, in consequence, provoke increases in both internal and international migration. In this particular period in which we find ourselves, characterized by globalization, the international community has become aware that the re-emergence of these diseases poses an important risk for public health underlines the necessity to adopt appropriate strategies for their prevention and control. The re-emerging diseases of the twenty-first century are a serious problem for public health and even though there has been enormous progress in medical science and in the battle against infectious diseases, they are still a long way from being really brought under control. A well organized monitoring system would enable the epidemiological characteristics of the infectious diseases to be analyzed and the success or otherwise of preventive interventions to be precisely evaluated. For this reason, the World Health Organization and the European Union have discussed the formation of a collaborative network for the monitoring and control of re-emerging diseases and has initiated special programmes.

    1996-12-31

    A priority of government and business in the United States and other first tier industrial countries continues to be the improvement of science, mathematics and technology (SMT) instruction in pre university level education. The U.S. federal government has made SMT instruction an educational priority and set goals for improving it in the belief that science, math and technology education are tied to our economic well being and standard of living. The new national standards in mathematics education, science education and the proposed standards in technology education are all aimed at improving knowledge and skills in the essential areas that the federal government considers important for protecting our technological advantage in the world economy. This paper will discuss a pilot project for establishing graphical Web capability in a limited number of rural Nevada schools (six) with support from the US Department of Energy (DOE) and the state of Nevada. The general goals of the pilot project are as follows: (1) to give rural teachers and students access to up to date science information on the Web; (2) to determine whether Web access can improve science teaching and student attitudes toward science in rural Nevada schools; and (3) to identify science content on the Web that supports the National Science Standards and Benchmarks. A specific objective that this paper will address is stated as the following question: What potential do nuclear energy information office web sites offer for changing student attitudes about nuclear energy and creating greater nuclear literacy.

The study was conducted in the same 12 Asian countries, with the assistance of members of the International Development Research Centre’s PANdora distance education research network. The data were generated by network members in Bhutan, Cambodia, India, Indonesia, Laos, Mongolia, the Philippines, Sri Lanka, Pakistan, Singapore, Thailand, and Vietnam. Additional data for the follow-up study were collected in China. Using a ‘traceroute’ routine, the study indicates that webpage loading time is linked to the complexity of the Internet routes between Web users and the host server. It is indicated that distance educators can apply such information in the design of improved online delivery and mirror sites, notably in areas of the developing world which currently lack an effective infrastructure for online education.

    Full Text Available Diabetic kidney disease – which is defined by elevated urine albumin excretion or reduced glomerular filtration rate (GFR or both – is a serious complication that occurs in 20% to 40% of all diabetics. In this review we try to highlight the prevalence of diabetic nephropathy which is not uncommon complication of diabetes all over the world. The prevalence of diabetes worldwide has extended epidemic magnitudes and is expected to affect more than 350 million people by the year 2035. There is marked racial/ethnic besides international difference in the epidemiology of diabetic kidney disease which could be explained by the differences in economic viability and governmental infrastructures. Approximately one-third of diabetic patients showed microalbuminuria after 15 years of disease duration and less than half develop real nephropathy. Diabetic kidney disease (DKD is more frequent in African-Americans, Asian-Americans, and Native Americans. Progressive kidney disease is more frequent in Caucasians patients with type 1 than type 2 diabetes mellitus (DM, although its overall prevalence in the diabetic population is higher in patients with type 2 DM while this type of DM is more prevalent. Hyperglycemia is well known risk factor for in addition to other risk factors like male sex, obesity, hypertension, chronic inflammation, resistance to insulin, hypovitaminosis D, and dyslipidemia and some genetic loci and polymorphisms in specific genes. Management of its modifiable risk factors might help in reducing its incidence in the nearby future.

    In the next few years, several modest-sized telescopes around the world will be upgraded with autonomous laser adaptive optics systems based on the Robo-AO prototype deployed at the Palomar Observatory 1.5-m telescope. The prototype commenced scientific operations in June 2012 and more than 19,000 observations have since been performed at the ~0.12" visible-light diffraction limit. We are planning to move the prototype system to the 2.1-m telescope at Kitt Peak for a 3-year deployment which will serve a consortium of users including Caltech, the University of Hawai`i, IUCAA, NCU and institutions in China. Additionally, 2 months per year will be made available to the US astronomical community.New Robo-AO systems are in various stages of development: a clone by IUCAA for the 2-m IGO telescope in India; a natural guide star variant, KAPAO, by Pomona College at the 1-m Table Mountain telescope in California; and second generation Robo-AO systems are planned for the 3-m IRTF and 2.2-m University of Hawai'i telescopes on Maunakea, Hawai`i. The latter will exploit Maunakea's excellent observing conditions to provide higher Strehl ratios, sharper imaging, ~0.07", and correction to lambda = 400 nm. An additional infrared integral-field spectrograph will be fed by the UH 2.2-m Robo-AO system to quickly classify transients, such as supernovae and asteroids, discovered by the ATLAS system in Hawai`i.

    1998-01-01

    The Automated Space System Experimental Testbed (ASSET) system is a simple yet comprehensive real-world operations network being developed. Phase 3 of the ASSET Project was January-December 1997 and is the subject of this report. This phase permitted SSDL and its project partners to expand the ASSET system in a variety of ways. These added capabilities included the advancement of ground station capabilities, the adaptation of spacecraft on-board software, and the expansion of capabilities of the ASSET management algorithms. Specific goals of Phase 3 were: (1) Extend Web-based goal-level commanding for both the payload PI and the spacecraft engineer. (2) Support prioritized handling of multiple (PIs) Principle Investigators as well as associated payload experimenters. (3) Expand the number and types of experiments supported by the ASSET system and its associated spacecraft. (4) Implement more advanced resource management, modeling and fault management capabilities that integrate the space and ground segments of the space system hardware. (5) Implement a beacon monitoring test. (6) Implement an experimental blackboard controller for space system management. (7) Further define typical ground station developments required for Internet-based remote control and for full system automation of the PI-to-spacecraft link. Each of those goals are examined. Significant sections of this report were also published as a conference paper. Several publications produced in support of this grant are included as attachments. Titles include: 1) Experimental Initiatives in Space System Operations; 2) The ASSET Client Interface: Balancing High Level Specification with Low Level Control; 3) Specifying Spacecraft Operations At The Product/Service Level; 4) The Design of a Highly Configurable, Reusable Operating System for Testbed Satellites; 5) Automated Health Operations For The Sapphire Spacecraft; 6) Engineering Data Summaries for Space Missions; and 7) Experiments In Automated Health

    Full Text Available In a world where the internet and its image are becoming more and more important, this study is about the importance of Investment and Financial Services Companies web sites. Market competition, creates the need of studies, focused on assessing and analyzing the websites of companies who are active in this sector. Our study wants to respond at several questions related to Romanian Investment and Financial Services Companies web sites through four dimensions: content, layout, handling and interactivity. Which web sites are best and from what point of view? Where should financial services companies direct their investments to differentiate themselves and their sites? In fact we want to rank the 58 Investment and Financial Services Companies web sites based on 127 criteria. There are numerous methods for evaluating web pages. The evaluation methods are similar from the structural point of view and the most popular are: Serqual, Sitequal, Webqual / Equal EtailQ, Ewam, e-Serqual, WebQEM (Badulescu, 2008:58. In the paper: "Assessment of Romanian Banks E-Image: A Marketing Perspective" (Catana, Catana and Constantinescu, 2006: 4 the authors point out that there are at least four complex variables: accessibility, functionality, performance and usability. Each of these can be decomposed into simple ones. We used the same method, and we examined from the utility point of view, 58 web sites of Investment and Financial Services Companies based on 127 criteria following a procedure developed by Institut fur ProfNet Internet Marketing, Munster (Germany. The data collection period was 1-30 September 2010. The results show that there are very large differences between corporate sites; their creators are concentrating on the information required by law and aesthetics, neglecting other aspects as communication and online service. In the future we want to extend this study at international level, by applying the same methods of research in 5 countries from

  4. Rapid and recent world-wide diversification of bluegrasses (Poa, Poaceae and related genera.

    Full Text Available Rapid species diversifications provide fascinating insight into the development of biodiversity in time and space. Most biological radiations studied to date, for example that of cichlid fishes or Andean lupines, are confined to isolated geographical areas like lakes, islands or island-like regions. Using DNA sequence data of the ribosomal internal transcribed spacer (ITS for many species of the Poa alliance, a group comprising about 775 C3 grass species, revealed rapid and parallel diversifications in various parts of the world. Some of these radiations are restricted to isolated areas like the Andes, whereas others are typical of the lowlands of mainly the northern hemisphere. These radiations thus are not restricted to island-like areas and are seemingly actively ongoing. The ages of the diversifying clades are estimated to be 2.5-0.23 million years (Myr. Conservative diversification rates in the Poa alliance amount to 0.89-3.14 species per Myr, thus are in the order of, or even exceeding, other instances of well-known radiations. The grass radiations of the mainly cold-adapted Poa alliance coincide with the Late Tertiary global cooling, which resulted in the retreat of forests and the subsequent formation of cold-adapted grasslands especially in the northern, but also in parts of the southern hemisphere. The cold tolerance, suggested to be one of the ecological key innovations, may have been acquired during the early diversification of the subfamily Pooideae, but became significant millions of years later during the Pliocene/Pleistocene radiation of the Poa alliance.

  5. Nutrient Intake Values for Folate during Pregnancy and Lactation Vary Widely around the World

    Full Text Available Folate is a B-vitamin with particular importance during reproduction due to its role in the synthesis and maintenance of DNA. Folate is well known for its role in preventing neural tube defects (NTDs during the periconceptional period. There is also an increased need for folate throughout pregnancy to support optimal growth and development of the fetus and blood volume expansion and tissue growth of the mother. During lactation, women are at risk of folate deficiency due to increased demands to accommodate milk folate levels. Nutrient Intake Values (NIVs for folate have been calculated to take into account additional needs during pregnancy and lactation. However, these values vary widely between countries. For example, the folate requirement that is set to meet the needs of almost all healthy women during pregnancy varies from 300 µg/day in the United Kingdom to 750 µg/day in Mexico. Currently, there is no accepted standardized terminology or framework for establishing NIVs. This article reviews country-specific NIVs for folate during pregnancy and lactation and the basis for setting these reference values.

    Software-based medical knowledge packages (MKPs) are packages of highly structured medical knowledge that can be integrated into various health-care information systems or the World Wide Web. They have been established to provide different forms of clinical decision support such as textual interpretation of combinations of laboratory rest results, generating diagnostic hypotheses as well as confirmed and excluded diagnoses to support differential diagnosis in internal medicine, or for early identification and automatic monitoring of hospital-acquired infections. Technically, an MKP may consist of a number of inter-connected Arden Medical Logic Modules. Several MKPs have been integrated thus far into hospital, laboratory, and departmental information systems. This has resulted in useful and widely accepted software-based clinical decision support for the benefit of the patient, the physician, and the organization funding the health care system.

    2013-04-01

    Full Text Available The unexpected wide spread use of WWW and dynamically increasing nature of the web creates new challenges in the web mining since the data in the web inherently unlabelled, incomplete, non linear, and heterogeneous. The investigation of user usage behaviour on WWW is real time problem which involves multiple conflicting measures of performance. These measures make not only computational intensive butalso needs to the possibility of be unable to find the exact solution. Unfortunately, the conventional methods are limited to optimization problems due to the absence of semantic certainty and presence of human intervention. In handling such data and overcome the limitations of conventional methodologies it is necessary to use a soft computing model that can work intelligently to attain optimal solution. To achieve the optimized solution for investigating the web user usage behaviour, the authors in the present paper proposes an Intelligent Optimal Genetic Model, IOGM, which is designed as an optimization tool based on the concept of natural genetic systems. Initially, IOGM comprise a set of individual solutions or chromosomes called the initial population. Later, biologically inspired operators create a new and potentially better population. Finally, by the theory of evolution, survive only optimal individuals from the population and then generate the next biological population. This process is terminated as when an acceptable optimal set of visited patterns is found or after fixed time limit. Additionally, IOGM strengthen by its ability to estimate the optimal stopping time of process. The proposed soft computing model ensures the identifiable features like learning, adaptability, self-maintenance and self-improvement. To validate the proposed system, several experiments were conducted and results proven this are claimed in this paper

    Visualization tools for biological data are often limited in their ability to interactively integrate data at multiple scales. These computational tools are also typically limited by two-dimensional displays and programmatic implementations that require separate configurations for each of the user's computing devices and recompilation for functional expansion. Towards overcoming these limitations we have developed "ePlant" (http://bar.utoronto.ca/eplant) - a suite of open-source world wide web-based tools for the visualization of large-scale data sets from the model organism Arabidopsis thaliana. These tools display data spanning multiple biological scales on interactive three-dimensional models. Currently, ePlant consists of the following modules: a sequence conservation explorer that includes homology relationships and single nucleotide polymorphism data, a protein structure model explorer, a molecular interaction network explorer, a gene product subcellular localization explorer, and a gene expression pattern explorer. The ePlant's protein structure explorer module represents experimentally determined and theoretical structures covering >70% of the Arabidopsis proteome. The ePlant framework is accessed entirely through a web browser, and is therefore platform-independent. It can be applied to any model organism. To facilitate the development of three-dimensional displays of biological data on the world wide web we have established the "3D Data Display Initiative" (http://3ddi.org).

    This study has attempted to demonstrate the feasibility of obtaining information specific to foot and ankle orthopaedics from the World Wide Web (WWW). Six search engines (Lycos, AltaVista, Infoseek, Excite, Webcrawler, and HotBot) were used in scanning the Web for the following key words: "cavus foot," "diabetic foot," "hallux valgus,"and "pes equinovarus." Matches were classified by language, provider, type, and relevance to medical professionals or to patients. Sixty percent (407 sites) of the visited websites contained information intended for use by physicians and other medical professionals; 30% (206 sites) were related to patient information; 10% of the sites were not easily classifiable. Forty-one percent (169 sites) of the websites were commercially oriented homepages that included advertisements.

    The hit rate, a major metric for evaluating proxy caches, is mostly limited by the replacementstrategy of proxy caches. However, in traditional proxy caches, the hit rate does not usually successfullypredict how well a proxy cache will perform because the proxy cache counts any hit in its caching space whichhas many pages without useful information, so its replacement strategy fails to determine which pages to keepand which to release. The proxy cache efficiency can be measured more accurately using the valid hit rateintroduced in this paper. An efficient replacement strategy based on the Site-Graph model for WWW(World-Wide Web) documents is also discussed in this paper. The model analyzes user access behavior as abasis for the replacement strategy. Simulation results demonstrate that the replacement strategy improvesproxy cache efficiency.``

    A great barrier to the use of Internet resources for patient education is the concern over the quality of information available. We conducted a study to determine what information was available in Web pages, both within text and metadata source code, that could be used in the assessment of information quality. Analysis of pages retrieved from 97 unique sites using a simple keyword search for "breast cancer treatment" on a generic and a health-specific search engine revealed that basic publishing elements were present in low frequency: authorship (20%), attribution/references (32%), disclosure (41%), and currency (35%). Only one page retrieved contained all four elements. Automated extraction of metadata elements from the source code of 822 pages retrieved from five popular generic search engines revealed even less information. We discuss the design of a metadata-based system for the evaluation of quality of medical content on the World Wide Web that addresses current limitations in ensuring quality.

    In the handful of years since the World Wide Web (WWW or Web) came into being, Web sites have developed at an astonishing rate. With the influx of Web pages comes a disparity of site types, including personal homepages, commercial sales sites, and educational data. The variety of sites and the deluge of information contained on the Web exemplify the individual nature of the WWW. Whereas some people argue that it is this eclecticism which gives the Web its charm, we propose that sites which are repositories of technical data would benefit from standardization. This paper proffers a methodology for publishing ecological research on the Web. The template we describe uses capabilities of HTML (the HyperText Markup Language) to enhance the value of the traditional scientific paper.

    Using an open-access distribution model, the Crystallography Open Database (COD, http://www.crystallography.net) collects all known 'small molecule / small to medium sized unit cell' crystal structures and makes them available freely on the Internet. As of today, the COD has aggregated ~150,000 structures, offering basic search capabilities and the possibility to download the whole database, or parts thereof using a variety of standard open communication protocols. A newly developed website provides capabilities for all registered users to deposit published and so far unpublished structures as personal communications or pre-publication depositions. Such a setup enables extension of the COD database by many users simultaneously. This increases the possibilities for growth of the COD database, and is the first step towards establishing a world wide Internet-based collaborative platform dedicated to the collection and curation of structural knowledge.

    Full Text Available This article has evaluated the impact of using Meta tag on the improvement of information retrieval of the World Wide Web. So it reviewed the research papers that have examined Meta tag as a means to enhance information retrieval. Results showed there were some researches that have confirmed the using of Meta tags was efficient for improving information retrieval of the web, but results of a research that has done by Mohamed (2006 indicated no significant difference in the rank of pages that include metadata and those that don’t include any metadata. Therefore more studies should be done in this field. In general, Meta tags can provide site owners and authors with a degree of control over how a web page is indexed and this is a considerable advantage that it shouldn’t be ignore easily.

    2009-12-01

    The papers in this special feature have been contributed by scientific partners in international research projects and from former PhD students of the Editor-in-Chief of this journal, Professor Dr Peter Hauptmann. The motivation for this feature is the occasion of Peter Hauptmann's 65th birthday on 24 July 2009 and his retirement from his chair at the Otto-von-Guericke-University, Magdeburg, Germany this autumn. Peter graduated in Physics at the Technical University Dresden and received his PhD from the Technical University Leuna-Merseburg in 1973. He habilitated in 1979. With his appointment at the Faculty of Electrical Engineering and Information Technology in 1985 the Chair of Measurement Science extended its profile to the fast growing area of sensors. Peter was one of the very early developers of ultrasonic sensor systems for process monitoring and quality assurance. The working style here was characteristic of all his future activities. He combined his background in theory and experiment on ultrasonic wave propagation and its application to material science with the advantages of rapidly developing capabilities in microelectronics and data processing. The results have meanwhile found their way into products that are now on the market worldwide. Germany's reunification opened the door to the international sensor community and the most challenging sensor research areas. Peter Hauptmann very soon became a well respected colleague and was consequently appointed as member of the Technical Program Committee of the most important sensor conferences, elected member and head of expert groups of research associations and funding organizations, and of course reviewer of many scientific journals. Nowadays Peter Hauptmann can rightly be called one of the key players in the area of sensors. Professor Hauptmann's research interests combine fundamental aspects of the sensor transduction scheme with application issues up to the use of the sensor system in the industrial world

  3. Identification and characterization of highly divergent simian foamy viruses in a wide range of new world primates from Brazil.

    Full Text Available Foamy viruses naturally infect a wide range of mammals, including Old World (OWP and New World primates (NWP, which are collectively called simian foamy viruses (SFV. While NWP species in Central and South America are highly diverse, only SFV from captive marmoset, spider monkey, and squirrel monkey have been genetically characterized and the molecular epidemiology of SFV infection in NWPs remains unknown. We tested a large collection of genomic DNA (n = 332 comprising 14 genera of NWP species for the presence of SFV polymerase (pol sequences using generic PCR primers. Further molecular characterization of positive samples was carried out by LTR-gag and larger pol sequence analysis. We identified novel SFVs infecting nine NWP genera. Prevalence rates varied between 14-30% in different species for which at least 10 specimens were tested. High SFV genetic diversity among NWP up to 50% in LTR-gag and 40% in pol was revealed by intragenus and intrafamilial comparisons. Two different SFV strains infecting two captive yellow-breasted capuchins did not group in species-specific lineages but rather clustered with SFVs from marmoset and spider monkeys, indicating independent cross-species transmission events. We describe the first SFV epidemiology study of NWP, and the first evidence of SFV infection in wild NWPs. We also document a wide distribution of distinct SFVs in 14 NWP genera, including two novel co-speciating SFVs in capuchins and howler monkeys, suggestive of an ancient evolutionary history in NWPs for at least 28 million years. A high SFV genetic diversity was seen among NWP, yet these viruses seem able to jump between NWP species and even genera. Our results raise concerns for the risk of zoonotic transmission of NWP SFV to humans as these primates are regularly hunted for food or kept as pets in forest regions of South America.

    Background. AIDA is a widely available downloadable educational simulator of glucose-insulin interaction in diabetes. Methods. A web-based version of AIDA was developed that utilises a server-based architecture with HTML FORM commands to submit numerical data from a web-browser client to a remote web server. AIDA online, located on a remote server, passes the received data through Perl scripts which interactively produce 24 hr insulin and glucose simulations. Results. AIDA online allows users to modify the insulin regimen and diet of 40 different prestored "virtual diabetic patients" on the internet or create new "patients" with user-generated regimens. Multiple simulations can be run, with graphical results viewed via a standard web-browser window. To date, over 637,500 diabetes simulations have been run at AIDA online, from all over the world. Conclusions. AIDA online's functionality is similar to the downloadable AIDA program, but the mode of implementation and usage is different. An advantage to utilising a server-based application is the flexibility that can be offered. New modules can be added quickly to the online simulator. This has facilitated the development of refinements to AIDA online, which have instantaneously become available around the world, with no further local downloads or installations being required.

    Full Text Available Background. AIDA is a widely available downloadable educational simulator of glucose-insulin interaction in diabetes. Methods. A web-based version of AIDA was developed that utilises a server-based architecture with HTML FORM commands to submit numerical data from a web-browser client to a remote web server. AIDA online, located on a remote server, passes the received data through Perl scripts which interactively produce 24 hr insulin and glucose simulations. Results. AIDA online allows users to modify the insulin regimen and diet of 40 different prestored “virtual diabetic patients” on the internet or create new “patients” with user-generated regimens. Multiple simulations can be run, with graphical results viewed via a standard web-browser window. To date, over 637,500 diabetes simulations have been run at AIDA online, from all over the world. Conclusions. AIDA online’s functionality is similar to the downloadable AIDA program, but the mode of implementation and usage is different. An advantage to utilising a server-based application is the flexibility that can be offered. New modules can be added quickly to the online simulator. This has facilitated the development of refinements to AIDA online, which have instantaneously become available around the world, with no further local downloads or installations being required.

    CERN Document Server

    Schmeisser, Gerhard

    2014-01-01

    Paul Butzer, who is considered the academic father and grandfather of many prominent mathematicians, has established one of the best schools in approximation and sampling theory in the world. He is one of the leading figures in approximation, sampling theory, and harmonic analysis. Although on April 15, 2013, Paul Butzer turned 85 years old, remarkably, he is still an active research mathematician. In celebration of Paul Butzer’s 85th birthday, New Perspectives on Approximation and Sampling Theory is a collection of invited chapters on approximation, sampling, and harmonic analysis written by students, friends, colleagues, and prominent active mathematicians. Topics covered include approximation methods using wavelets, multi-scale analysis, frames, and special functions. New Perspectives on Approximation and Sampling Theory requires basic knowledge of mathematical analysis, but efforts were made to keep the exposition clear and the chapters self-contained. This volume will appeal to researchers and graduate...

  20. Affordances of students' using the World Wide Web as a publishing medium in project-based learning environments

    Science.gov (United States)

    Bos, Nathan Daniel

    This dissertation investigates the emerging affordance of the World Wide Web as a place for high school students to become authors and publishers of information. Two empirical studies lay groundwork for student publishing by examining learning issues related to audience adaptation in writing, motivation and engagement with hypermedia, design, problem-solving, and critical evaluation. Two models of student publishing on the World Wide Web were investigated over the course of two 11spth grade project-based science curriculums. In the first curricular model, students worked in pairs to design informative hypermedia projects about infectious diseases that were published on the Web. Four case studies were written, drawing on both product- and process-related data sources. Four theoretically important findings are illustrated through these cases: (1) multimedia, especially graphics, seemed to catalyze some students' design processes by affecting the sequence of their design process and by providing a connection between the science content and their personal interest areas, (2) hypermedia design can demand high levels of analysis and synthesis of science content, (3) students can learn to think about science content representation through engagement with challenging design tasks, and (4) students' consideration of an outside audience can be facilitated by teacher-given design principles. The second Web-publishing model examines how students critically evaluate scientific resources on the Web, and how students can contribute to the Web's organization and usability by publishing critical reviews. Students critically evaluated Web resources using a four-part scheme: summarization of content, content, evaluation of credibility, evaluation of organizational structure, and evaluation of appearance. Content analyses comparing students' reviews and reviewed Web documents showed that students were proficient at summarizing content of Web documents, identifying their publishing

  1. Toward Robust Climate Baselining: Objective Assessment of Climate Change Using Widely Distributed Miniaturized Sensors for Accurate World-Wide Geophysical Measurements

    Energy Technology Data Exchange (ETDEWEB)

    2001-11-13

    A gap-free, world-wide, ocean-, atmosphere-, and land surface-spanning geophysical data-set of three decades time-duration containing the full set of geophysical parameters characterizing global weather is the scientific perquisite for defining the climate; the generally-accepted definition in the meteorological community is that climate is the 30-year running-average of weather. Until such a tridecadal climate base line exists, climate change discussions inevitably will have a semi-speculative, vs. a purely scientific, character, as the baseline against which changes are referenced will be at least somewhat uncertain. The contemporary technology base provides ways-and-means for commencing the development of such a meteorological measurement-intensive climate baseline, moreover with a program budget far less than the {approx}$2.5 B/year which the US. currently spends on ''global change'' studies. In particular, the recent advent of satellite-based global telephony enables real-time control of, and data-return from, instrument packages of very modest scale, and Silicon Revolution-based sensor, data-processing and -storage advances permit 'intelligent' data-gathering payloads to be created with 10 gram-scale mass budgets. A geophysical measurement system implemented in such modern technology is a populous constellation 03 long-lived, highly-miniaturized robotic weather stations deployed throughout the weather-generating portions of the Earths atmosphere, throughout its oceans and across its land surfaces. Leveraging the technological advances of the OS, the filly-developed atmospheric weather station of this system has a projected weight of the order of 1 ounce, and contains a satellite telephone, a GPS receiver, a full set of atmospheric sensing instruments and a control computer - and has an operational life of the order of 1 year and a mass-production cost of the order of $20. Such stations are effectively &apos

    The applications of DNA profiling aim to identify perpetrators, missing family members and disaster victims in forensic investigations. Single nucleotide polymorphisms (SNPs) based forensic applications are emerging rapidly with a potential to replace short tandem repeats (STRs) based panels which are now being used widely, and there is a need for a well-designed SNP panel to meet such challenge for this transition. Here we present a panel of 175 SNP markers (referred to as Fudan ID Panel or FID), selected from ∼3.6 million SNPs, for the application of personal identification. We optimized and validated FID panel using 729 Chinese individuals using a next generation sequencing (NGS) technology. We showed that the SNPs in the panel possess very high heterozygosity as well as low within- and among-continent differentiations, enabling FID panel exhibit discrimination power in both regional and worldwide populations, with the average match probabilities ranging from 4.77×10(-71) to 1.06×10(-64) across 54 world populations. With the advent of biomedical research, the SNPs connecting physical anthropological, physiological, behavioral and phenotypic traits will be eventually added to the forensic panels that will revolutionize criminal investigation.

    Nanomachine and molecular machines are state-of-the-art objects in current physics and chemistry. The operation and manufacturing of nanosize machines are top-level technologies that we have desired to accomplish for a long time. There have been extensive attempts to design and synthesize nanomachines. In this paper, we review the these attempts using the concept of nanoarchitectonics toward the design, synthesis, and testing of molecular machinery, especially at interfacial media. In the first half of this review, various historical attempts to design and prepare nanomachines are introduced as well as their operation mechanisms from their basic principles. Furthermore, in order to emphasize the importance and possibilities of this research field, we also give examples of two new challenging topics in the second half of this review: (i) a world wide nanocar race and (ii) new modes of nanomachine operation on water. The nanocar race event involves actual use of nanomachines and will take place in the near future, and nanomachine operation of a dynamic fluidic interface will enable future advances in nanomachine science and technology.

  4. A large-scale study of the World Wide Web: network correlation functions with scale-invariant boundaries

    CERN Document Server

    Luduena, G A; Kaczor, Gregor; Gros, Claudius

    2013-01-01

    We performed a large-scale crawl of the World Wide Web, covering 6.9 Million domains and 57 Million subdomains, including all high-traffic sites of the Internet. We present a study of the correlations found between quantities measuring the structural relevance of each node in the network (the in- and out-degree, the local clustering coefficient, the first-neighbor in-degree and the Alexa rank). We find that some of these properties show strong correlation effects and that the dependencies occurring out of these correlations follow power laws not only for the averages, but also for the boundaries of the respective density distributions. In addition, these scale-free limits do not follow the same exponents as the corresponding averages. In our study we retain the directionality of the hyperlinks and develop a statistical estimate for the clustering coefficient of directed graphs. We include in our study the correlations between the in-degree and the Alexa traffic rank, a popular index for the traffic volume, fi...

    As we all know too well, building up a collaborative community around a software infrastructure is not easy. Besides recruiting enthusiasts to work as part of it, mostly for free, to succeed you also need to overcome a number of technical, sociological, and, to our surprise, some political hurdles. The ALMA Common Software (ACS) was developed at ESO and partner institutions over the course of more than 10 years. While it was mainly intended for the ALMA Observatory, it was early on thought as a generic distributed control framework. ACS has been periodically released to the public through an LGPL license, which encouraged around a dozen non-ALMA institutions to make use of ACS for both industrial and educational applications. In recent years, the Cherenkov Telescope Array and the LLAMA Observatory have also decided to adopt the framework for their own control systems. The aim of the "ACS Community" is to support independent initiatives in making use of the ACS framework and to further contribute to its development. The Community provides access to a growing network of volunteers eager to develop ACS in areas that are not necessarily in ALMA's interests, and/or were not within the original system scope. Current examples are: support for additional OS platforms, extension of supported hardware interfaces, a public code repository and a build farm. The ACS Community makes use of existing collaborations with Chilean and Brazilian universities, reaching out to promising engineers in the making. At the same time, projects actively using ACS have committed valuable resources to assist the Community's work. Well established training programs like the ACS Workshops are also being continued through the Community's work. This paper aims to give a detailed account of the ongoing (second) journey towards establishing a world-wide open source collaboration around ACS. The ACS Community is growing into a horizontal partnership across a decentralized and diversified group of

    2011-07-01

    The New World Screwworm (NWS), Cochliomyia hominivorax, was eradicated from the USA, Central America to Panama, but in most tropical regions of Latin America, the NWS is still a serious threat to livestock, provoking estimated annual losses of US$ 1.8 billion in Brazil. Between January and May 2009, a pilot-project was performed at the Brazil-Uruguay border. As the results were positive, novel regional Area-Wide Integrated Pest Management projects are being planned. To set a mass-rearing center based in South America is strategic when considering long-term programs. In partnership with CENA/USP and the Biofactory MOSCAMED Brazil, a project to produce sterile NWS started on 2009. The project aimed to maintain a colony of a regional NWS strain, to develop a mass-rearing system and a sterilization protocol by X rays, and to study the sterility induction in regional strains. A colony was successfully established. The adults were kept in cages and fed on a diet (honey and spray dried egg). The larvae were reared in a medium made of spray dried blood, spray dried egg, milk, water, formalin and Ecogel. Egg hatch has been of 80 {+-} 10%. From F{sub 1} to F{sub 22}, the total amount of pupae produced was about 38 L ({approx} 315,400 pupae). The mean adult emergence and sex ratio were 86.7 {+-} 3% and 0.59 {+-} 0.08 respectively. The mean pupal weight was 47.1 {+-} 1.7 mg. The estimated X ray doses to induce 99% sterility in males and females were 43.7 Gy and 47.5 Gy, respectively. To produce 1.5 L of pupae, the current cost is about US$ 15.00. (author)

  11. Evolution and connectivity in the world-wide migration system of the mallard: Inferences from mitochondrial DNA

    Directory of Open Access Journals (Sweden)

    Kraus Robert HS

    2011-11-01

    Full Text Available Abstract Background Main waterfowl migration systems are well understood through ringing activities. However, in mallards (Anas platyrhynchos ringing studies suggest deviations from general migratory trends and traditions in waterfowl. Furthermore, surprisingly little is known about the population genetic structure of mallards, and studying it may yield insight into the spread of diseases such as Avian Influenza, and in management and conservation of wetlands. The study of evolution of genetic diversity and subsequent partitioning thereof during the last glaciation adds to ongoing discussions on the general evolution of waterfowl populations and flyway evolution. Hypothesised mallard flyways are tested explicitly by analysing mitochondrial mallard DNA from the whole northern hemisphere. Results Phylogenetic analyses confirm two mitochondrial mallard clades. Genetic differentiation within Eurasia and North-America is low, on a continental scale, but large differences occur between these two land masses (FST = 0.51. Half the genetic variance lies within sampling locations, and a negligible portion between currently recognised waterfowl flyways, within Eurasia and North-America. Analysis of molecular variance (AMOVA at continent scale, incorporating sampling localities as smallest units, also shows the absence of population structure on the flyway level. Finally, demographic modelling by coalescence simulation proposes a split between Eurasia and North-America 43,000 to 74,000 years ago and strong population growth (~100fold since then and little migration (not statistically different from zero. Conclusions Based on this first complete assessment of the mallard's world-wide population genetic structure we confirm that no more than two mtDNA clades exist. Clade A is characteristic for Eurasia, and clade B for North-America although some representatives of clade A are also found in North-America. We explain this pattern by evaluating competing

  15. Global Patterns of Material Flows and their Socio-Economic and Environmental Implications: A MFA Study on All Countries World-Wide from 1980 to 2009

    Directory of Open Access Journals (Sweden)

    Stefan Giljum

    2014-03-01

    Full Text Available This paper assesses world-wide patterns of material extraction, trade, consumption and productivity based on a new data set for economy-wide material flows, covering used materials for all countries world-wide between 1980 and 2009. We show that global material extraction has grown by more than 90% over the past 30 years and is reaching almost 70 billion tonnes today. Also, trade volumes in physical terms have increased by a factor of 2.5 over the past 30 years, and in 2009, 9.3 billion tonnes of raw materials and products were traded around the globe. China has turned into the biggest consumer of materials world-wide and together with the US, India, Brazil and Russia, consumes more than 50% of all globally extracted materials. We also show that the per-capita consumption levels are very uneven, with a factor of more than 60 between the country with the lowest and highest consumption in 2009. On average, each human being consumed 10 tonnes of materials in 2009, 2 tonnes more than in 1980. We discuss whether decoupling of economies’ growth from resource use has occurred and analyse interrelations of material use with human development. Finally, we elaborate on key environmental problems related to various material groups.

  16. The world-wide increase in tuberculosis: how demographic changes, HIV infection and increasing numbers in poverty are increasing tuberculosis.

    Science.gov (United States)

    Davies, Peter D O

    2003-01-01

    After more than a century of decline, in the mid 1980s tuberculosis began to increase in some developed countries. Health care workers were then forced to look to the developing world, where they found tuberculosis to be out of control, in many countries. It is now appreciated that tuberculosis is not only increasing globally but is likely to do so beyond the next decade for three principal reasons. First, demographically as the expected population increase will be greatest in areas of the world where tuberculosis is most prevalent, particularly middle Africa and South Asia. Secondly, the increase of HIV, which renders the host uniquely susceptible to tuberculosis, is occurring in the same areas of the world and is already causing an increase in tuberculosis case rates of up to tenfold. Thirdly, as more and more people are forced to live in poverty, where poor nutrition and crowded conditions lead to the spread of tuberculosis, the disease risk will be compounded. Sound medical management, particularly the use of the five components of directly observed therapy, will relieve the situation. But until world conditions of poverty and HIV spread are addressed, it is unlikely that tuberculosis can be controlled.

    Full Text Available Polarizing the views on the emergence of Information security around the campus arenas of higher education institutions is the utmost erg of both developing and developed nations in this post catastrophic era of September 11, 2001 where the unthinkable is now potentially a daily reality with root causes of information breaching, misusing and thereby initiating terrorism which have presented the world with many challenges in accommodating peoples personal and work lives to a changed environment. To bring the resources of the academic world to bear on both national policy and on the individual responses and so thus to cope up with and to mitigate such riskier environment various IT security approaches have been proposed. While among them Soft IT Security approach (SITS is highly lucrative now-a-days due to its simplicity and effectiveness in the sector of Information security especially in higher education, however it is unable to secure the all types of educational environment using a general framework due to not most of these environments being homogeneous also because of little focused on cultures and believes of these regions. Addressing this issue, a new security management scheme namely Robust IT Security Balancing (RITS-B Approach is proposed in this paper which is focused on to develop such strategic framework of security environment where facts, national and regional perspectives will be merged up to lead to a proactive leadership and information security system without violating the freedom and openness that is at the very heart of the academia. A quantitative survey has been conducted and the security facts and findings are compared with the three basic survey questionnaires namely more secure than two years ago, system is secure and security program is successful with a 4 point likert scale. The analyzed data shows that institutions which implemented RITS-B approach in their arena either partially or fully feel more high in the above

    These are the proceedings of a meeting in honour of Massimo Capaccioli at the occasion of his 70th birthday. The conference aimed at summarizing the results from the main current and past digital sky survey projects and at discussing how these can be used to inspire ongoing projects and better plan the future ones. Over the last decades, digital sky surveys performed with dedicated telescopes and finely-tuned wide-field cameras, have revolutionized astronomy. They have become the main tool to investigate the nearby and far away universe, thus providing new insights in the understanding of the galaxy structure and assembly across time, the dark components of the universe, as well as the history of our own galaxy. They have also opened the time domain leading to a new understanding of the transient phenomena in the universe. By providing public access to top quality data, digital surveys have also changed the everyday practice of astronomers who have become less dependent on direct access to large observing ...

    Species' geographical distributions are tracking latitudinal and elevational surface temperature gradients under global climate change. To evaluate the opportunities to track these gradients across space, we provide a first baseline assessment of the steepness of these gradients for the world's terrestrial birds. Within the breeding ranges of 9,014 bird species, we characterized the spatial gradients in temperature along latitude and elevation for all and a subset of bird species, respectively. We summarized these temperature gradients globally for threatened and non-threatened species and determined how their steepness varied based on species' geography (range size, shape, and orientation) and projected changes in temperature under climate change. Elevational temperature gradients were steepest for species in Africa, western North and South America, and central Asia and shallowest in Australasia, insular IndoMalaya, and the Neotropical lowlands. Latitudinal temperature gradients were steepest for extratropical species, especially in the Northern Hemisphere. Threatened species had shallower elevational gradients whereas latitudinal gradients differed little between threatened and non-threatened species. The strength of elevational gradients was positively correlated with projected changes in temperature. For latitudinal gradients, this relationship only held for extratropical species. The strength of latitudinal gradients was better predicted by species' geography, but primarily for extratropical species. Our findings suggest threatened species are associated with shallower elevational temperature gradients, whereas steep latitudinal gradients are most prevalent outside the tropics where fewer bird species occur year-round. Future modeling and mitigation efforts would benefit from the development of finer grain distributional data to ascertain how these gradients are structured within species' ranges, how and why these gradients vary among species, and the capacity

    The ROADNet project has enabled the acquisition and storage of diverse data streams through seamless integration of the Antelope Real Time System (ARTS) with (for example) ecological, seismological and geodetic instrumentation. The robust system architecture allows researchers to simply network data loggers with relational databases; however, the ability to disseminate these data to policy makers, scientists and the general public has (until recently) been provided on an 'as needed' basis. The recent development of a Datascope interface to the popular open source scripting language PHP has provided an avenue for presenting near real time data (such as integers, images and movies) from within the ARTS framework easily on the World Wide Web. The interface also indirectly provided the means to transform data types into various formats using the extensive function libraries that accompany a PHP installation (such as image creation and manipulation, data encryption for sensitive information, and XML creation for structured document interchange through the World Wide Web). Using a combination of Datascope and PHP library functions, an extensible tool-kit is being developed to allow data managers to easily present their products on the World Wide Web. The tool-kit has been modeled after the pre-existing ARTS architecture to simplify the installation, development and ease-of-use for both the seasoned researcher and the casual user. The methodology and results of building the applications that comprise the tool-kit are the focus of this presentation, including procedural vs. object oriented design, incorporation of the tool-kit into the existing contributed software libraries, and case-studies of researchers who are employing the tools to present their data. http://anf.ucsd.edu

    A Chinese proverb says that happiness is when friends coming from far and away meet and talk to each other. These wise words could very well be used to sum up the celebrations in honour of the 80th birthdays of Magda and Torleif Ericson, a couple in the normal sense of the word and often also in the field of physics. Torleif joined CERN's Theory Division in 1960, initially to work at the intersection of nuclear and particle physics at the Synchrocyclotron, and retired in 1995.   During the celebratory event on 17 September, speakers reviewed the depth and breadth of the contributions which both Torleif and Magda have made to theoretical physics in general and to nuclear physics in particular. José Bernabeu, Guy Chanfray, Wolfram Wiese, Achim Richter and Anthony Thomas all covered the considerable research that has been stimulated by the Ericson-Ericson correlation(s) over the past 50 years.

    This special issue of Surface Science has been prepared to honor Professor Gabor A. Somorjai on the occasion of his 80th birthday. Professor Somorjai was born on May 4, 1935 in Budapest, Hungary. In 1953 he enrolled as a chemical engineering student at the Technical University of Budapest. Gabor was an active participant in the Hungarian Revolution of 1956. When the Soviet military crushed the revolution, he had to leave the country by walking across the border with his sister and his future wife. After immigrating to the USA in 1957, he applied to begin graduate studies and was accepted at the University of California, Berkeley. Gabor received a PhD in Chemistry in 1960, only three years later. Following a short sojourn at IBM, he returned to Berkeley in 1964 to take up a faculty position in the Department of Chemistry and the Lawrence Berkeley National Laboratory, which he still holds today. For the interested reader, more can be learned about Gabor's fascinating life in his autobiography, "An American Scientist: The Autobiography of Gabor A. Somorjai.

  12. Does tree harvesting in riparian areas increase stream sedimentation and turbidity - world-wide experience relative to Australia.

    Neary, D.; Smethurst, P.; Petrone, K.

    2009-04-01

    A typical improved-pasture property in the high-rainfall zone of Australia contains 0.5-2.0 km of waterways per 100 ha. Nationwide, some 25-30 million ha of improved pasture contains about 100,000 km of streams, of which about 75% are currently un-buffered and contributing to soil and water degradation. Farmers and natural resource managers are considering ways to enhance environmental outcomes at farm and catchment scales using stream-side buffers of trees and other perennial vegetation. Benefits of buffers include improved water quality, biodiversity, carbon sequestration and aesthetics. Lack of sound information and funding for establishing and managing buffer zones is hindering wide-scale adoption of this practice. Stream-side areas of farms are generally highly productive (wet and nutrient-rich) and contain a high biodiversity, but they are also high-risk zones for soil and water values and stock safety. Development of options based on a balance between environmental and economic outcomes would potentially promote wider adoption. Australian codes of forest practice currently discourage or prevent harvesting of trees in streamside buffers. These codes were developed exclusively for large-scale native forests and industrial-scale plantations, and were applicable to farm forestry as now required. In countries including USA and Germany trees in stream-side buffers are harvested using Best Management Practices. Trees may grow at a faster rate in riparian zones and provide a commercial return, but the impacts of tree establishment and harvesting on water yield and quality must be evaluated. However, there have been few designed experiments investigating this problem. Australia has recently initiated studies to explore the use of high-value timber species and associated vegetation in riparian zones to improve water quality, particularly suspended sediment. Preliminary information from the Yan Yan Gurt Catchment in Victoria indicate that forested riparian strips can

    The application of World wide web as an active component of environmental decision support system is still largely unexplored. Environmental problems are distributed in nature, both from the physical and from the social point of view; the Web is thus an ideal tool to share concepts and decisions among multiple interested parties. Also Virtual Reality (VR) that has not find, up to know, a large application in the development and teaching of environmental models. The paper shows some recent applications that highlight the potential of these tools. [Italian] L'uso della rete Internet come componente attiva di sistemi di supporto alle decisioni e' ancora largamente da esplorare. Soprattutto in campo ambientale, i problemi si presentano naturalmente come distribuiti sia sul territorio sia tra le componenti sociali, e quindi il World Wide Web e' uno strumento ideale per condividere informazioni e azioni. Anche la realta' virtuale (VR) e' stata finora poco usata per lo sviluppo e l'addestramento sui problemi ambientali. L'articolo mostra invece alcuni esempi che mettono in luce il grande potenziale di questi strumenti.

    2016-01-01

    Background Off-road vehicles are popular and thrilling for youth outside urban settings, yet sometimes result in a serious crash that requires emergency medical care. The relation between birthdays and the subsequent risk of an off-road vehicle crash is unknown. Methods We conducted a population-based before-and-after longitudinal analysis of youth who received emergency medical care in Ontario, Canada, due to an off-road vehicle crash between April 1, 2002, and March 31, 2014. We identified youth injured in an off-road vehicle crash through population-based health-care databases of individuals treated for medical emergencies. We included youth aged 19 years or younger, distinguishing juniors (age ≤ 15 years) from juveniles (age ≥ 16 years). Results A total 32,777 youths accounted for 35,202 emergencies due to off-road vehicle crashes within six months of their nearest birthday. Comparing the six months following a birthday to the six months prior to a birthday, crashes increased by about 2.7 events per 1000 juniors (18.3 vs 21.0, p juveniles (19.2 vs 19.8, p = 0.61). Conclusions Off-road vehicle crashes leading to emergency medical care increase following a birthday in youth below age 16 years. An awareness of this association might inform public health messages, gift-giving practices, age-related parental permissions, and prevention by primary care physicians. PMID:27695070

  16. Happy birthday neuroleptics! 50 years later: la folie du doute.

    Science.gov (United States)

    Stip, Emmanuel

    2002-05-01

    Given that we are celebrating the 50th birthday of neuroleptics introduction in psychiatry, the author proposes to take a look at certain results related to therapeutic practice. After a brief chronological literature review of the clinical practices and theoretical models that have controlled drug treatment of schizophrenia, the author presents a critical review of four meta-analyses. Since Delay, Deniker and Harl's initial report, the story of neuroleptics comprises several periods. In 1963, the hyper-dopaminergic theory of psychoses was proposed. Another period began with models mainly based on the serotonin/dopamine relative blockade receptor hypothesis. More recently, a new framework to understand the differential effect of antipsychotics is related to the appropriate modulation (e.g., fast dissociation) of the D2 receptor alone. The concept of atypicality has become a new vista for research and to market new compounds. However, after 50 years of neuroleptic drugs, are we able to answer the following simple questions: Are neuroleptics effective in treating schizophrenia? Is there a difference between atypical and conventional neuroleptics? How do the efficacy and safety of newer antipsychotic drugs compare with those of clozapine? Actually, the answers yielded by these simple questions by meta-analysis should elicit in us a good deal of humility. If we wish to base psychiatry on evidence-based medicine, we run a genuine risk in taking a closer look at what has long been considered fact. Each psychiatrist must continue to be critical, sceptical, optimistic (not overoptimistic) and to learn in order to integrate the positive aspects of our growing knowledge base.

    Western and Soviet laser cooling communities. In neutral Finland, accessible to both parties, he organized informal workshops that crucially sped the development of laser cooling. The importance of these meetings is highlighted in Bill Phillips' Nobel lecture in 1997 [6]. However, as the emphasis in laser cooling moved from a semiclassical description to quantum theory, Stig started to look for new avenues of research. My contact with Stig came when I went to see him for an MSc thesis topic. This involved polarization spectroscopy and modelling of an experiment performed by the laser spectroscopy group (Birger Ståhlberg) at the University of Helsinki. Without knowing anything about quantum optics I then found myself immediately in one of the Finnish-Soviet workshops on quantum electronics in the small town of Porvoo slightly east of Helsinki. There I met people like Juha Javanainen, Peter Knight, Axel Schenzle and Vladimir Chebotayev, and my own career in quantum optics began, working on the mathematics of the Landau-Zener model and how to apply it and other such models in molecular excitation by femtosecond pulses for my PhD thesis. This work was done together with Barry Garraway, who was a postdoc in Helsinki in the early 1990s. The Finnish-Soviet meetings continued for a while, and in 1990 we even got to travel to Novosibirsk (and back, too). During its existence (1964-1996), the Research Institute of Theoretical Physics (TFT) had a tremendous impact on physics in Finland. Short and long stays by visitors provided a unique and high-level environment for local researchers, the research fields covered a wide range of physics, and for many Finns returning from abroad it provided a place to stay until something more permanent turned up. Thus many researchers who later became professors had, at some point in their career, a connection with TFT. As a director Stig was very broad-minded and without this the happy atmosphere of TFT could not have existed. In the 1980s young

    Breast cancer patient's expectation and choice of reconstruction is increasing and patients often satisfy their information needs outside clinic time by searching the world wide web. The aim of our study was to analyse the quality of content and extent of information regarding breast reconstruction available on YouTube videos and whether this is an appropriate additional source of information for patients. A snapshot qualitative and quantitative analysis of the first 100 videos was performed after the term 'breast reconstruction' was input into the search window of the video sharing website www.youtube.com on the 1st of September 2011. Qualitative categorical analysis included patient, oncological and reconstruction factors. It was concluded that although videos uploaded onto YouTube do not provide comprehensive information, it is a useful resource that can be utilised in patient education provided comprehensive and validated videos are made available.

    Predation and competition among native and invasive species are difficult to study in aquatic environments. Identification of preys from semi-digested body parts sampled from stomach contents of the predator is very challenging. Recent studies were mainly based on use of DNA extracted from stomach content to identify the prey species. This study presents the molecular evidence that reveals the predation of critically endangered Aphanius transgrediens by world-wide invasive Gambusia affinis for a better understanding of the link between the invasion and the extinction of native species in freshwater ecosystems. DNA samples were extracted from semi-digested stomach contents of the invader and short fragments of mitochondrial NADH1 gene were amplified using species-specific primers designed in this study to make identification at species level. Existence of both the prey and the predator species were also confirmed using environmental DNA extracted from water samples.

    We describe a partnership approach in use at UC Berkeley's Center for EUV Astrophysics (CEA) that facilitates the adaptation of astrophysics data and information---in particular from NASA's EUVE satellite---for use in the K--12 classroom. Our model is founded on a broad collaboration of personnel from research institutions, centers of informal science teaching, schools of education, and K--12 schools. Several CEA-led projects follow this model of collaboration and have yielded multimedia, Internet-based, lesson plans for grades 6 through 12 that are created and distributed on the World Wide Web (http://www.cea.berkeley.edu/Education). Use of technology in the classroom can foster an environment that more closely reflects the processes scientists use in doing research (Linn, diSessa, Pea, & Songer 1994, J.Sci.Ed.Tech., ``Can Research on Science Learning and Instruction Inform Standards for Science Education?"). For instance, scientists rely on technological tools to model, analyze, and ultimately store data. Linn et al. suggest introducing technological tools to students from the earliest years to facilitate scientific modeling, scientific collaborations, and electronic communications in the classroom. Our investigation aims to construct and evaluate a methodology for effective participation of scientists in K--12 education, thus facilitating fruitful interactions with teachers and other educators and increasing effective use of technology in the classroom. We describe several team-based strategies emerging from these project collaborations. These strategies are particular to the use of the Internet and World Wide Web as relatively new media for authoring K--12 curriculum materials. This research has been funded by NASA contract NAS5-29298, NASA grant ED-90033.01-94A to SSL/UCB, and NASA grants NAG5-2875 and NAGW-4174 to CEA/UCB.

    Rodriguez, Lindsey M; Young, Chelsie M; Tomkins, Mary M; DiBello, Angelo M; Krieger, Heather; Neighbors, Clayton

    2016-01-01

    The present research examined how various locations and companions were associated with hazardous drinking during 21st birthday celebrations. The sample included 912 college students (57% female) who completed an online survey to examine 21st birthday drinking. Locations included bars, friends' houses, restaurants, outdoor barbecues, homes, parents' homes, and Fraternity/Sorority houses. Companions included friends, family members, casual acquaintances, roommates, significant others, Fraternity/Sorority members, and none (alone). Participants consumed an average of 7.6 drinks and reached an average eBAC of .15 during their 21st birthday celebrations. Locations accounted for 20%/18% of the variance in number of drinks and eBAC, respectively, whereas companions accounted for 23%/20% of the variance. Drinking with romantic partners was associated with less drinking, whereas drinking with Fraternity/Sorority members was associated with more drinking. Stepwise regressions combining locations and companions suggested that, overall, celebrating in a bar setting and with Fraternity and Sorority members were the strongest variables associated with drinking. With the exception of a bar setting, companions were the most important contextual factors associated with 21st birthday drinking.

    Dommes, Aurelie; Chevalier, Aline; Rossetti, Marilyne

    2010-04-01

    This pilot study investigated the age-related differences in searching for information on the World Wide Web with a search engine. 11 older adults (6 men, 5 women; M age=59 yr., SD=2.76, range=55-65 yr.) and 12 younger adults (2 men, 10 women; M=23.7 yr., SD=1.07, range=22-25 yr.) had to conduct six searches differing in complexity, and for which a search method was or was not induced. The results showed that the younger and older participants provided with an induced search method were less flexible than the others and produced fewer new keywords. Moreover, older participants took longer than the younger adults, especially in the complex searches. The younger participants were flexible in the first request and spontaneously produced new keywords (spontaneous flexibility), whereas the older participants only produced new keywords when confronted by impasses (reactive flexibility). Aging may influence web searches, especially the nature of keywords used.

  4. Selfie and the city: a world-wide, large, and ecologically valid database reveals a two-pronged side bias in naive self-portraits.

    Directory of Open Access Journals (Sweden)

    Nicola Bruno

    Full Text Available Self-portraits are more likely to show the artist's right than left cheek. This phenomenon may have a psychobiological basis: Self-portraitists often copy their subject from mirrors and, if they prefer to present their left cheek (more expressive due to right-lateralization of emotions to the mirror, this would result in a right-cheek bias in the painting. We tested this hypothesis using SelfieCity (3200 selfies posted on Instagram from December 4 through 12, 2013 from New York, Sao Paulo, Berlin, Moskow, and Bangkok, which includes two selfie-taking styles: a "standard" (photograph of selfie-taker and a "mirror" (photograph of mirror reflection of selfie-taker style. We show that the first style reveals a left cheek bias, whereas the second reveals a right cheek bias. Thus side biases observed in a world-wide, large, and ecologically valid database of naïve self-portraits provide strong support for a role of psychobiological factors in the artistic composition of self-portraits.

    2007-01-01

    As medical information becomes increasingly available and individuals take a more active role in managing their personal health, it is essential for scholars to better understand the general public's information-seeking behavior. The study reported here explores the use of the World Wide Web to seek health information in a contemporary information-media environment. Drawing from uses and gratifications theory and the comprehensive model of health information seeking, perceptions of traditional information sources (e.g., mass media, one's health care provider, etc.) are posited to predict use of the Web to seek health information and perceptions of information acquired from searches. Data from the Health Information National Trends Survey (HINTS; N = 3982) were analyzed to test study hypotheses. Trust in information-oriented media, entertainment-oriented media, and one's health care provider all predicted Web use behavior and perceptions. The implications of the findings for research on information seeking and the role of the Web in patient empowerment are discussed.

    In the frame of the present preoccupation on the global climatic change and its influence in the human activities, the possible mitigation scenarios of green house effect gases are analyzed (GEG) in the world-wide scope, the contribution of carbon dioxide future emissions as main green house effect gas originating from the burning of fossil fuels; taking into account two large classifications: Developed and developing countries. In accordance with the world-wide evolution in the 1972-1995 period and to diverse adjustments of future emissions a study of the necessary levels of these emissions is made to obtain the stabilization of the greenhouse effect gases in the atmosphere in a level in the vicinity of 550 ppmv. The considered projections are: emissions in accordance with the present tendency, basic scenario of the Intergovernmental Panel of Climatic Change (Panel Intergubernamental de Cambio Climatico) (IPCC-IS92a), mitigation proposals of the Netherlands (NL-1%, NL-2%) and profiles that entail the atmospheric CO{sub 2} stabilization. In addition the reduction in the contribution of future emissions that the developing countries would have to face to obtain the stabilization are compared, emissions that will depend on changes in factors such as population growth, economic, emissions per capita and carbon content of the power fuels, changes that would have to take place in all the countries, or certain key countries, in order to arrive to the necessary atmospheric stabilization of the emissions in accordance with those profiles.

    Orchiston, Wayne

    2005-01-01

    This unique work celebrates the 60th birthday of Professor Woodruff Sullivan III (University of Washington, Seattle). The ‘Woodfest’ conference attracted some of the world’s leading astrobiologists and historians of astronomy, so it is no surprise this book provides a collection of key papers and reviews on the history of astronomy, astrobiology and sundials. The emphasis on radio astronomy in the historical papers is a fitting reminder that Woody is widely acknowledged as the world’s leading authority in this field. But there are also papers on astrobiology, which reflect his intimate involvement in this exciting multidisciplinary field. The papers on sundials reveal another passion and his quest to make Seattle the sundial capital of North America! This book will appeal to professional and amateur astronomers, and is a tribute to one of the world’s most remarkable astronomers.

    2014-02-01

    Full Text Available This paper presents a solution to real-world delive ry problems for home delivery services where a large number of roads exist in cities and the tra ffic on the roads rapidly changes with time. The methodology for finding the shortest-travel-tim e tour includes a hybrid meta-heuristic that combines ant colony optimization with Dijkstra’s al gorithm, a search technique that uses both real-time traffic and predicted traffic, and a way to use a real-world road map and measured traffic in Japan. Experimental results using a map of central Tokyo and historical traffic data indicate that the proposed method can find a better solution than conventional methods.

  3. Tribute to Professor Padma Kant Shukla on the occasion of his 60th birthday

    As the Journal of Plasma Physics so fittingly dedicates this current volume to honor Professor Padma Kant Shukla, for his extraordinary and prolific contributions to the field, over a period spanning four decades, on the occasion of his 60th birthday, it gives me great pleasure to contribute this personal tribute. Padma is without doubt one of the preeminent plasma theorists of his generation with a productivity that is phenomenal and perhaps unmatched (well in excess of 1000). What is truly impressive is not only his extraordinary productivity but also the depth and breadth of his contributions, which while being centered in plasma physics, bridge many other disciplines including condensed matter physics, particle physics, and geophysics. Although I was familiar with Padma's work, in several areas, earlier, I first met him about 20 years ago, when he began working in a field of great interest to me, namely dusty plasmas. Very quickly Padma became a leader in this very new and rapidly developing field, in particular, pioneering the fascinating area of waves in dusty plasmas; predicting the existence, among others, of the very low frequency dust acoustic mode, which was spectacularly observed subsequently in the laboratory, and has been cited about 1000 times since. During this time I got to know Padma very well while participating in numerous international meetings convened by him and also while hosting him, several times, as a visiting professor at my home institution, and observing his multifaceted talents as an outstanding scholar, inspiring mentor, tireless organizer, and committed humanitarian. While Padma's accomplishments are extraordinary, what makes them even more noteworthy is his personal history. Padma came from a family of modest means in a small Indian village. He was the first member of his extended family who went to college, mainly due to the efforts of the village schoolteacher who obviously recognized the young student's innate talent. Living up

    Full Text Available Durante la pasada década, las posiciones del Banco Mundial se orientaron hacia la defensa de la orientación competitiva y de mercado de la educación superior, mientras que UNESCO reafirmó el estatuto de servicio público de ella y abogó por mantener un importante financiamiento estatal, con el objetivo de desarrollar una educación superior igualmente accesible a todos sobre la base del mérito. Este artículo es un ejercicio de educación superior internacional comparada. Presenta reflexiones sobre todo respecto a los siguientes temas: principales tendencias globales de la educación superior; modelos mundiales de financiamiento; visión global del financiamiento de las universidades; financiamiento, políticas de educación superior, cooperación internacional e internacionalización; financiamiento de la educación superior en Europa. En resumen, concluye que diversificar las fuentes de financiamiento es positivo y necesario, pero esto no debe implicar una reducción o abdicación del Estado en el financiamiento de la educación terciaria.During the past decade, the World Bank's higher education guidelines were geared towards competition and the market place, while Unesco reaffirmed the statute of its public service and advocated the importance of State financing, with the purpose of developing a higher education that is equally accessible to all and based on merit. This article is a comparison of international higher education. It presents considerations on the following topics: main global tendencies for higher education; world models of financing; global vision of university financing; financing, higher education policies, international cooperation and internationalization; higher education financing in Europe. In short, it concludes that diversifying the sources of financing is both positive and necessary, though this must not imply a reduction or abdication of the State in the financing of higher education.

The reader will find new insights into the composition of solar-system and galactic matter and fractionation processes affecting samples of this matter. These findings are based on measurements by recent space instruments, ground-based studies, and theoretical advances. The five symposium sessions reflect the areas of research presented in this book: linking primordial to solar composition, planetary samples, solar sources and fractionation processes, interstellar gas, and cosmic rays. The structure of the volume at hand largely follows the structure of the symposium. It includes almost all of the overview and invited papers and many of the contributed ones.

  8. Multiparticle Correlations in Mesoscopic Scattering: Boson Sampling, Birthday Paradox, and Hong-Ou-Mandel Profiles

    Urbina, Juan-Diego; Kuipers, Jack; Matsumoto, Sho; Hummel, Quirin; Richter, Klaus

    2016-03-01

    The interplay between single-particle interference and quantum indistinguishability leads to signature correlations in many-body scattering. We uncover these with a semiclassical calculation of the transmission probabilities through mesoscopic cavities for systems of noninteracting particles. For chaotic cavities we provide the universal form of the first two moments of the transmission probabilities over ensembles of random unitary matrices, including weak localization and dephasing effects. If the incoming many-body state consists of two macroscopically occupied wave packets, their time delay drives a quantum-classical transition along a boundary determined by the bosonic birthday paradox. Mesoscopic chaotic scattering of Bose-Einstein condensates is, then, a realistic candidate to build a boson sampler and to observe the macroscopic Hong-Ou-Mandel effect.

  12. Consuming children and making mothers: birthday parties, gifts and the pursuit of sameness

    Full Text Available Children's birthday parties, and related consumption, form an integral part of the social process of mothering in contemporary consumer culture. From the choosing of the 'right' present to the arrangement of the 'appropriate' party theme, an enormous pressure is exerted upon mothers to maintain social equilibrium through the circulation of their children and gifts amongst and across households. Ethnographic research in Britain suggests that the economic growth of children's party provision and services is coupled with a popular discourse that laments the loss of 'authentic' kinship-based birthday parties and home-made provisioning. In contrast to this spoken discourse, this article reveals how women in fact avidly embrace market goods and services; as a means of generating a culture of sameness that avoids the risks (to the motherhood as a collective, localised phenomenon of exceptional or overtly accomplished mothering. Commercialised, mass produced goods and birthday services are used as a means of limiting expressive gift relations and hospitality. In this sense, the search for sameness, through the cultural practice of making children's parties, is at once liberating and potentially oppressive in its strive for the normative and its inadvertent exclusion of 'other' care-givers. Furthermore, children and their related material culture are consumed, through the birthday party circuit, as a means of generating specific types of mothering.Festas de aniversário infantil, e o consumo ligado a elas, formam uma parte integral do processo social da criação dos filhos na cultura de consumo contemporânea. Da escolha do presente "certo" à preparação do tema "apropriado" para a festa, uma grande pressão é exercida sobre as mães para manter um equilíbrio através da circulação de suas crianças e seus presentes entre e além das famílias.

    Full Text Available This working paper brings together concepts and ideas about the role of information in the future of humanity. Different views have emerged within the international debate on sustainable development - a global industrialization view centers on sustaining global industrialization and a new moral order that advocates societal downscaling and de-industrialization based on regional self-sufficiency to preserve humanity. This working paper briefly outlines these approaches to sustainable development and their relationship to information science research. Both views are distinguished by their approach to de-industrialization. Global industrialization includes pockets of de-industrialization of communities and regions, and societal down scaling includes a de-industrialization process to a sustainable community. De-industrialization is therefore a growing interdisciplinary area of research within sociology, urban planning and policy, and economics. However, information science research is becoming primarily concerned with the informational dimensions of the global industrialization - not de-industrialization. Despite the growing interdisciplinary literature on sustainable development and de-industrialization, the informational aspects of these important issues have yet to be fully explored.

    This paper pays a tribute to Dr. Frank I Tovey on his 90th birthday which happens on September 1, 2011, and briefly describes the major findings in his research career and contributions as follows. The geographical prevalence of duodenal ulceration is related to staple diets. Unrefined wheat and maize, soya, certain pulses and millets are associated with a low prevalence while refined wheat, maize and rice, yams, cassava and green banana with a high prevalence. Predominant foodstuffs from low prevalence areas are ulceroprotective in rat peptic ulcer models. The protective activity lies in the lipid fraction present in these foodstuffs. The lipid fraction also promotes ulcer healing, is active both orally and intramuscularly and is ulceroprotective against non-steroidal anti-inflammatory drugs (NSAIDs). The phospholipids and phytosterols present in the lipid have been identified to be responsible for this protective activity. The combination of phospholipids and phytosterols may be of value in the prevention and treatment of duodenal ulceration and protection against the ulcerogenic effect of NSAIDs.

    The main objective of Radio Frequency Identification systems is to provide fast identification for tagged objects. However, there is always a chance of collision, when tags transmit their data to the reader simultaneously. Collision is a time-consuming event that reduces the performance of RFID systems. Consequently, several anti-collision algorithms have been proposed in the literature. Dynamic Framed Slotted ALOHA (DFSA) is one of the most popular of these algorithms. DFSA dynamically modifies the frame size based on the number of tags. Since the real number of tags is unknown, it needs to be estimated. Therefore, an accurate tag estimation method has an important role in increasing the efficiency and overall performance of the tag identification process. In this paper, we propose a novel estimation technique for DFSA anti-collision algorithms that applies birthday paradox theory to estimate the number of tags accurately. The analytical discussion and simulation results prove that the proposed method increases the accuracy of tag estimation and, consequently, outperforms previous schemes.

    This paper intends to summarize the scientific production of Angelo Luongo on the occasion of his Sixtieth Birthday, focusing on his main contributions in the field of Mechanics. The task will not be easy because of the breadth of his scientific production, only apparently attributable to a restricted number of keywords. In fact, even when the work seems purely algorithmic, speculation on the physical and mechanical aspects of the problem is always present, providing new interpretations and innovative openings to a careful reader. Similarly, also the works, which apparently seem to be high-level applications, always reserve methodological aspects that are not negligible. The editorial choice to divide his papers through a small number of keywords is certainly simplistic, but offers the possibility to better highlight all the connections among his variegated production. The most original contributions of Angelo Luongo in the context of perturbation methods, linear and nonlinear dynamics and control, elastic buckling and structural analysis, bifurcation and stability of non-conservative systems, are discussed in detail. Finally, the Angelo Luongo's central role in the creation and development of activities of the international research center M&MoCS is pointed out.

The real burden of B. cereus outbreaks is actually poorly known in Italy. We report a B. cereus foodborne outbreak that occurred in a pub in Bari (Italy on January 22nd 2012 during a birthday party, promptly reported by the pub owner. MATERIALS AND METHODS: Between January 22nd and 24th 2012, we performed a retrospective cohort study among the guests of the party to identify risk factors associated with illness. Leftovers of different meals were available for microbiological analysis. Faecal specimens were collected from cases. RESULTS: A total of 12 cases among the 13 customers (attack rate: 92% were reported. All cases had consumed basmati rice and sweet and sour vegetables (aetiological fraction: 100%. B. cereus was isolated from both basmati rice served during the party and faecal specimens. DISCUSSION: The close collaboration between the pub owner and the public health officers and the possibility to test food leftovers and stool samples contributed to prevent further cases.

  16. Phase transitions in number theory: from the birthday problem to Sidon sets.

    Science.gov (United States)

    Luque, Bartolo; Torre, Iván G; Lacasa, Lucas

    2013-11-01

    In this work, we show how number theoretical problems can be fruitfully approached with the tools of statistical physics. We focus on g-Sidon sets, which describe sequences of integers whose pairwise sums are different, and propose a random decision problem which addresses the probability of a random set of k integers to be g-Sidon. First, we provide numerical evidence showing that there is a crossover between satisfiable and unsatisfiable phases which converts to an abrupt phase transition in a properly defined thermodynamic limit. Initially assuming independence, we then develop a mean-field theory for the g-Sidon decision problem. We further improve the mean-field theory, which is only qualitatively correct, by incorporating deviations from independence, yielding results in good quantitative agreement with the numerics for both finite systems and in the thermodynamic limit. Connections between the generalized birthday problem in probability theory, the number theory of Sidon sets and the properties of q-Potts models in condensed matter physics are briefly discussed.

    Kraepelin described but one single specific sign for all forms of dementia praecox (later: schizophrenia) and coined a new word for it, "Zerfahrenheit" (various translations: distraction, dilapidation, incoherence, among others). What he meant by it, clearly results from Kraepelin's description even now. The origin of the idea could been found in German philosophy of the times of enlightenment, when it had been described already in a distinct way. That time coined the word "Verrücktheit" for it (usual translation: mental derangement; better translations would be the same as for "Zerfahrenheit"). Because of the influence of French psychiatry with its quite different background and the hurly burly about paranoia (Heinroth's Greek translation for "Verrücktheit") the knowledge of the sign got lost. Kraepelin restored the original meaning, without referring however to the sources directly. In spite of having been acknowledged as a specific sign for dementia praecox by all German psychiatrists, only one decade after the first description a new process of unclearing recommenced. This bow curved from Eugen Bleuler via Kurt Schneider and others to DSM III/IV and ICD-10. In the current paper we follow Kraepelin's process of clearing via all 9 editions of his textbook of psychiatry. Since the German original of Kraepelin's first extended description currently can be found only in larger libraries, the integral text of it is being reprinted (in English a recent translation by Jacques M. Quen is available). No corrections or changes are necessary. Kraepelin's 150th birthday is the best occasion for reminding of what remains unique in the clinical unity of schizophrenia, which for ever is linked to his name. It still is a solid sign for schizophrenia, for all its various forms.

    Full Text Available Je breiter der Infrastruktur-Anschluss eines Landes an das World Wide Web, desto größer die Angriffsfläche im Fall eines Netzkriegs. Die Messung der virtuellen Kampfkraft erfolgt auf Basis von drei Faktoren: Offensivkraft, Defensivfähigkeit und die Abhängigkeit vom Internet. Die USA verfügen als "Supermacht" zwar über die größte virtuelle Offensivkraft, gleichzeitig steht die Nation Cyberangriffen sehr verwundbar gegenüber. Dagegen sind in Nordkorea kaum Systeme vom Internet abhängig. Obwohl die offensiven Netzkriegskapazitäten Nordkoreas verhältnismäßig gering sind, präsentiert sich die virtuelle Kampfkraft des nordkoreanischen Regimes in Bestform. Die Verwundbarkeit ziviler Systeme, insbesondere der Energieversorgung, muss in direkter Korrelation mit deren Anknüpfung an das Internet betrachtet werden. The more broadly connected a country’s infrastructure and energy distribution, the greater its vulnerability in the event of a cyber war. Measuring this virtual fighting power is based on three factors: offensive and defensive strength, as well as dependency on the Internet. As a superpower, the USA has the greatest virtual offensive strength available. At the same time, the nation is most susceptible to cyber attacks and therefore most vulnerable. By contrast, North Korea’s offensive cyber fighting power is relatively small, but its overall cyber war capabilities are cutting-edge. The vulnerability of civil systems, especially power supply, must be viewed in direct correlation to their connection to the Internet.

    This book arose from a conference on “Singularities and Computer Algebra” which was held at the Pfalz-Akademie Lambrecht in June 2015 in honor of Gert-Martin Greuel’s 70th birthday. This unique volume presents a collection of recent original research by some of the leading figures in singularity theory on a broad range of topics including topological and algebraic aspects, classification problems, deformation theory and resolution of singularities. At the same time, the articles highlight a variety of techniques, ranging from theoretical methods to practical tools from computer algebra. Greuel himself made major contributions to the development of both singularity theory and computer algebra. With Gerhard Pfister and Hans Schönemann, he developed the computer algebra system SINGULAR, which has since become the computational tool of choice for many singularity theorists. The book addresses researchers whose work involves singularity theory and computer algebra from the PhD to expert level.

His father, Milan Drazic, was a professor at the Faculty of Civil Engineering of the University of Belgrade, while his mother, Zorka, was also a civil engineer working for the City of Belgrade. These facts, as well as the entire intellectual entourage in the “Professors’ Colony” in Belgrade, predetermined his orientation to natural sciences and engineering. Thus, after finishing elementary school before WWII and secondary school by 1949, he entered the Faculty of Science and Mathematics (Department of Chemistry of the University of Belgrade. After his first year of study, he changed the school, enlisting in the faculty of Chemical Engineering (“Faculty of Technology” of the same University. He graduated from the Department of Chemical Technology with the highest grade in 1956. After graduation, he joined the teaching staff of the same school, in the Department of Physical Chemistry and Electrochemistry, in which he spent his entire career, commencing as an assistant lecturer and becoming a full professor. His affinity for science was supported by his wife Vera (b. Kuharic who was in the same profession and also became a university professor in physical chemistry. The family tradition continued with their two sons, Milan and Dusan, who also joined the academic world, becoming capable mathematician and computer scientists. Profesor Drazic taught very successfully a variety of subjects, such as Electrode Kinetics, Corrosion, Electrochemical Double Layer and Adsorption (postgraduate and finally, Physical Chemistry – a General Course.

    The collection of papers in this Festschrift represents the proceedings of a symposium held at the Norwegian Academy of Science and Letters on November 25-26, 1991, marking the occasion of the sixtieth birthday of Professor Jens Lothe. The symposium organizers attempted to invite contributors, either written, oral, or both, from a group of international scientists who have either collaborated with Jens in the past or whose work has had a significant impact in one of three areas in which Jens has focussed his own research interests, namely, statistical physics, elasticity and elastic waves, and the theory of dislocations in crystalline solids. The extent to which we have succeeded in obtaining a proper spectrum of contributors and contributions must be judged by the readers of this volume. It is rather rare in modern times to encounter a physicist such as Jens who has made seminal contributions in fields as diverse as the three included in this Festschrift. For this reason it is both historically interesting and instructive to follow the path that Jens Lothe's research career has taken him, since doing so clearly points out the international nature of the scientific endeavor and the fact that the search for scientific truth transcends national borders and governmental ideologies. Jens' postdoctoral studies at the University of Bristol in the late 1950s brought him in contact with an American postdoctoral student, John Hirth, who had worked on nucleation theory and condensation under the late Professor G M Pound at Carnegie-Mellon University. (Alex Maradudin, one of the contributors to the surface wave session of this symposium was also a postdoctoral fellow at Bristol at this time.) Both Lothe and Hirth had come to Bristol to acquaint themselves with dislocation theory; their first joint paper on double-kink nucleation theory was followed by numerous joint efforts, including their now-classic book Theory of Dislocations. Clearly, their interaction jelled. As legend

    2014-01-01

    To be habitable, a world (planet or moon) does not need to be located in the stellar habitable zone (HZ), and worlds in the HZ are not necessarily habitable. Here, we illustrate how tidal heating can render terrestrial or icy worlds habitable beyond the stellar HZ. Scientists have developed a language that neglects the possible existence of worlds that offer more benign environments to life than Earth does. We call these objects "superhabitable" and discuss in which contexts this term could be used, that is to say, which worlds tend to be more habitable than Earth. In an appendix, we show why the principle of mediocracy cannot be used to logically explain why Earth should be a particularly habitable planet or why other inhabited worlds should be Earth-like. Superhabitable worlds must be considered for future follow-up observations of signs of extraterrestrial life. Considering a range of physical effects, we conclude that they will tend to be slightly older and more massive than Earth and that their host star...

    Full Text Available This paper reports a comprehensive study of the politeness phenomenon in Pinter’s well-known play, “The Birthday party”. It aims at figuring out how politeness strategies are used by the characters and how the variables of power and distance influence the choice of politeness levels. In order to analyze the play’s text Brown and Levinson’s (1987 universal model of politeness was used. The model is characterized by three variables which are power, distance and rank extremity. Careful screening of the dialogues demonstrates that a good many of politeness strategies were used in the drama. However, different preferences were found in the use of the strategies towards the positive pole. Regarding the social distance the findings are consistent with Brown and Levinson’s theory predictions. The findings of this study suggest that the assertion of power is a complicated process which can not merely be explained by the high frequency of the use of certain strategies and an interlocutor’s power depends upon many factors like the role of the interlocutor and his/her status in the particular interaction, and in relation to the addressee.

    The purpose of the present study was to examine between- and within-person relationships among protective behavioral strategies (PBS), alcohol consumption, and related negative consequences during the 21st birthday week. Participants for the present study included undergraduate college students (n = 1,028) who turned 21 during three academic quarters at a large public northwestern university in the United States. Students completed a Web-based survey that comprised measures of 21st birthday PBS, alcohol consumption, and alcohol-related negative consequences. Between-person findings indicated that participants who used more manner of drinking PBS and fewer serious harm reduction PBS consumed fewer drinks and reached lower BACs. Results also showed that participants who used a greater number of limiting/stopping PBS and who used more manner of drinking PBS experienced fewer negative consequences. Within-person findings demonstrated that on days when participants used more limiting/stopping PBS, fewer manner of drinking PBS, and more serious harm reduction PBS than average they also consumed more drinks and reached higher BACs. When examining negative consequences, within-person results showed that on days when participants used more limiting/stopping PBS, fewer manner of drinking PBS, and more serious harm reduction PBS than usual they experienced more negative consequences. Discussion focuses on clarification of the association between PBS and drinking and implications for preventive interventions.

    A software program that searches and browses mission data emulates a Web browser, containing standard meta - phors for Web browsing. By taking advantage of back-end URLs, users may save and share search states. Also, since a Web interface is familiar to users, training time is reduced. Familiar back and forward buttons move through a local search history. A refresh/reload button regenerates a query, and loads in any new data. URLs can be constructed to save search results. Adding context to the current search is also handled through a familiar Web metaphor. The query is constructed by clicking on hyperlinks that represent new components to the search query. The selection of a link appears to the user as a page change; the choice of links changes to represent the updated search and the results are filtered by the new criteria. Selecting a navigation link changes the current query and also the URL that is associated with it. The back button can be used to return to the previous search state. This software is part of the MSLICE release, which was written in Java. It will run on any current Windows, Macintosh, or Linux system.

  14. Health and medication information resources on the World Wide Web.

    Science.gov (United States)

    Grossman, Sara; Zerilli, Tina

    2013-04-01

    Health care practitioners have increasingly used the Internet to obtain health and medication information. The vast number of Internet Web sites providing such information and concerns with their reliability makes it essential for users to carefully select and evaluate Web sites prior to use. To this end, this article reviews the general principles to consider in this process. Moreover, as cost may limit access to subscription-based health and medication information resources with established reputability, freely accessible online resources that may serve as an invaluable addition to one's reference collection are highlighted. These include government- and organization-sponsored resources (eg, US Food and Drug Administration Web site and the American Society of Health-System Pharmacists' Drug Shortage Resource Center Web site, respectively) as well as commercial Web sites (eg, Medscape, Google Scholar). Familiarity with such online resources can assist health care professionals in their ability to efficiently navigate the Web and may potentially expedite the information gathering and decision-making process, thereby improving patient care.

  15. The future of nuclear power: A world-wide perspective

    Science.gov (United States)

    Aktar, Ismail

    This study analyzes the future of commercial nuclear electric generation worldwide using the Environmental Kuznets Curve (EKC) concept. The Tobit panel data estimation technique is applied to analyze the data between 1980 and 1998 for 105 countries. EKC assumes that low-income countries increase their nuclear reliance in total electric production whereas high-income countries decrease their nuclear reliance. Hence, we expect that high-income countries should shut down existing nuclear reactors and/or not build any new ones. We encounter two reasons for shutdowns: economic or political/environmental concerns. To distinguish these two effects, reasons for shut down are also investigated by using the Hazard Model technique. Hence, the load factor of a reactor is used as an approximation for economic reason to shut down the reactor. If a shut downed reactor had high load factor, this could be attributable to political/environmental concern or else economic concern. The only countries with nuclear power are considered in this model. The two data sets are created. In the first data set, the single entry for each reactor is created as of 1998 whereas in the second data set, the multiple entries are created for each reactor beginning from 1980 to 1998. The dependent variable takes 1 if operational or zero if shut downed. The empirical findings provide strong evidence for EKC relationship for commercial nuclear electric generation. Furthermore, higher natural resources suggest alternative electric generation methods rather than nuclear power. Economic index as an institutional variable suggests higher the economic freedom, lower the nuclear electric generation as expected. This model does not support the idea to cut the carbon dioxide emission via increasing nuclear share. The Hazard Model findings suggest that higher the load factor is, less likely the reactor will shut down. However, if it is still permanently closed downed, then this could be attributable to political hostility against nuclear power. There are also some projections indicating which reactors are most/least likely to be shut downed from the logit model. We also project which countries are most likely to increase/decrease their nuclear reliance from the residuals of EKC model.

    Social relation plays an important role in a real community. Interaction patterns reveal relations among actors (such as persons, groups, companies), which can be merged into valuable information as a network structure. In this paper, we propose a new approach to extract inter-business relationship from the Web. Extraction of relation between a pair of companies is realized by using a search engine and text processing. Since names of companies co-appear coincidentaly on the Web, we propose an advanced algorithm which is characterized by addition of keywords (or we call relation words) to a query. The relation words are obtained from either an annotated corpus or the Web. We show some examples and comprehensive evaluations on our approach.

    Oral contraceptive pills are safe, effective, and available without a prescription in most countries. Despite support from the American Congress of Obstetricians and Gynecologists to provide oral contraceptives as an over-the-counter medication, US women are still required to have a prescription to obtain them. Use of online applications and the Internet has made most things easier to obtain in our society and this includes contraceptive methods. Several online ventures are now underway to enable US women to obtain oral contraceptives without visiting a medical provider's office. Women's health care professionals should encourage these novel approaches, as they will improve contraceptive access. As US women experiment with innovative health care models, providers will need to lead, follow, or be left behind.

    Full Text Available This article explores how the Web can serve as a resource for teaching modality in English to prospective teachers of ESL, EFL and ESP. The first section demonstrates how texts taken from two different registers on the Web can be used to teach epistemic modality (e.g. how modal verbs such as may and could express notions of probability and certainty. The second section explores how the Michigan Corpus of Academic Spoken English (MICASE can be searched to study deontic modality, specifically how the expressions should and might want to are used by teachers and advisors to give advice to students. The discussion demonstrates that teaching grammar is most effective when it is based on real data rather than contrived and decontextualized examples in grammar books.

    Full Text Available This article addresses the basic concepts of herbal technology which is used worldwide. 21st century is the century of Biology mechanical and propelled by scientific knowledge and hi-tech expertise. Herbal technology, are going to be the most influential elements that are fundamental for success and welfare for the people of nations. Information on the herbal technology was collected via electronic search (using pub med, scifinder, Google Scholar and web of science and library search for articles published in peer-reviewed journals. Furthermore, information also was obtained from some local books on ethnopharmacology. Nutraceutical are food or part of the food that grant medical or health benefits together with the prevention or cure of the disease. Cosmaceuticals are the largest accumulation to the health trade and are described as cosmetic products with drug; they are the fastest increased segment in the skin care market. Biopesticides are cost effective, safer, readily available, and ecological and therefore more environment- friendly and will offer substitute to conventional pesticides. Herbal drugs represent a major contribute to all the formally recognized systems of health in India. An upward trend has been experimental in the research on herbals. Export–Import reports reveal that the global trade of herbal technology and plant originated products is around US $250 billion. In the present article, an attempt has been made to present an overview of the herbal technology in the international market and intends to throw in the knowledge about Herbal drugs, Nutraceuticals, Cosmaceuticals, and Biopesticides which comes under herbal technology.

  5. Food irradiation: Standards, regulations and world-wide trade

    Science.gov (United States)

    Roberts, Peter B.

    2016-12-01

    There is an established framework of international standards for food irradiation covering human health, plant protection, labelling, dose delivery, quality assurance and facility management. Approximately 60 countries permit irradiation of one or more food or food classes. National regulations are briefly reviewed. Decontamination of spices, herbs and condiments remains the single largest application of irradiation. However, in recent years the market for irradiated fresh and processed meat has become firmly established in several countries including China and the USA. At least 10 countries have recently established bi-lateral agreements for trade in irradiated fresh fruits and vegetables using phytosanitary irradiation. Irradiated fresh produce volumes now exceed 20,000 t per year. Rationalization and greater consistency in labelling regulations would be advantageous to the future growth of applications of food irradiation.

    Zuraski, Steven M.; Fiorino, Steven T.

    2014-10-01

    This study quantifies the feasibility for a mobile sodium guidestar system. Simulations are run using the High Energy Laser End-to-End Operational Simulation (HELEEOS) software package with global sodium layer climatology data. Sodium layer data used was collected from the Optical Spectrograph and Infrared Imaging System (OSIRIS) sensor package on board the Odin satellite from 2005 through 2011 and provides a detailed global representation of the variable sodium layer occurring at an altitude of approximately 90 km in the atmosphere. This data is used in conjunction with the HELEEOS atmospheric propagation modeling to create realistic sodium guidestar models. The atmospheric effects for the laser propagation scattering model and creation of the sodium guidestar are defined in the worldwide probabilistic climatic database available in the HELEEOS software package. The simulations run evaluated the performance of a guidestar as viewed from along the propagation path and from non-propagation path viewing angles for engagement scenarios in various locations on earth. HELEEOS includes a fast-calculating, first principles, worldwide surface to 100 km, with extensions above 100 km to account for the sodium layer, atmospheric propagation and characterization package. This package enables the creation of profiles of temperature, pressure, water vapor content, optical turbulence, atmospheric particulates and hydrometeors as they relate to line-by-line layer transmission, path and background radiance at wavelengths from the ultraviolet to radio frequencies. HELEEOS is able to produce realistic evaluations of laser propagation, imaging, and adaptive optics systems by use of an end to end directed energy propagation model that incorporates probabilistic, climatological data from temporally and spatially variable meteorological, aerosol, and turbulence profiles. Specifically, HELEEOS performs its propagation calculations utilizing the following algorithms, models and datasets: the Scaling for HEL and Relay Systems (SHaRE) scaling law algorithms, High Resolution Transmission (HITRAN) database for molecular absorption, Global Aerosol Dataset (GADS), Advanced Navy Aerosol Model (ANAM), the Adaptive Optical Compensation of Thermal Blooming (AOTB) model, various turbulence models, and other physics based atmospheric propagation algorithms. HELEEOS was developed by the United States Air Force Institute of Technology (AFIT) under the sponsorship of the High Energy Laser Joint Technology Office.

    WIRED is a framework, written in Java, to build High Energy Physics event displays that can be used across the network. To guarantee portability across all platforms, WIRED is implemented in the Java language and uses the Swing user interface component set. It can be used as a stand-alone application or as an applet inside a WWW browser. The graphical user interface allows for multiple views and for multiple controls acting on those views. A detector tree control is available to toggle the visibility of parts of the events and detector geometry. XML (Extensible Markup Language), RMI (Remote Method Invocation) and CORBA loaders can be used to load event data as well as geometry data, and to connect to FORTRAN, C, C++ and Java reconstruction programs. Non-linear and non-Cartesian projections (e.g. fish-eye, rho-phi, rho-Z, phi-Z) provide special views to get a better understanding of events. WIRED has grown to be a framework in use and under development in several HEP experiments (ATLAS, CHORUS, DELPHI, LHCb, B...

    This pilot study tested the effects of an interactive nutrition education Web site on fruit, vegetable, and fat consumption in minority adolescents genetically at risk for Type 2 diabetes. A one-group nonexperimental pretest, posttest focus group design was used. Twenty-one sixth-grade to eighth-grade junior high adolescents who were minorities volunteered to participate. Participants received 5 hours of Web-based nutrition education over 3 weeks. A significant difference in fat consumption was supported from the computerized dietary assessment. No difference was found in fruit or vegetable consumption. Comparative data indicated a rise in body mass index (BMI) percentile from 88.03 (1999) to 88.40 (2002; boys) and 88.25 (1999) to 91.2 (2002; girls). Focus group responses supported the satisfaction of adolescents in the study with the use of the Web-based intervention for nutrition education. Healthy eating interventions using Web-based nutrition education should be further investigated with adolescents.

    A comparison of aerosol data acquired at five different sites around the globe is presented. All data has been acquired with the same instrumentation and representative size distributions for marine air masses at 10 m/s wind speed have been selected for comparison. Differences in the concentrations of larger and smaller aerosols at the various sites are explained in terms of fetch, trade winds, shielding, pollution, seawater temperature and phytoplankton bloom. The differences in size distribution induce significant differences in the extinction coefficients from the VIS to the LWIR at the various sites. Consequently, the transmission over a specific range also varies significantly. This suggests that a detailed analysis of the conditions at each site is necessary in order to understand the exact aerosol behavior and to correctly predict electro-optical propagation effects due to aerosols.

  18. Digital libraries and World Wide Web sites and page persistence.

    Directory of Open Access Journals (Sweden)

    Wallace Koehler

    1999-01-01

    Full Text Available Web pages and Web sites, some argue, can either be collected as elements of digital or hybrid libraries, or, as others would have it, the WWW is itself a library. We begin with the assumption that Web pages and Web sites can be collected and categorized. The paper explores the proposition that the WWW constitutes a library. We conclude that the Web is not a digital library. However, its component parts can be aggregated and included as parts of digital library collections. These, in turn, can be incorporated into "hybrid libraries." These are libraries with both traditional and digital collections. Material on the Web can be organized and managed. Native documents can be collected in situ, disseminated, distributed, catalogueed, indexed, controlled, in traditional library fashion. The Web therefore is not a library, but material for library collections is selected from the Web. That said, the Web and its component parts are dynamic. Web documents undergo two kinds of change. The first type, the type addressed in this paper, is "persistence" or the existence or disappearance of Web pages and sites, or in a word the lifecycle of Web documents. "Intermittence" is a variant of persistence, and is defined as the disappearance but reappearance of Web documents. At any given time, about five percent of Web pages are intermittent, which is to say they are gone but will return. Over time a Web collection erodes. Based on a 120-week longitudinal study of a sample of Web documents, it appears that the half-life of a Web page is somewhat less than two years and the half-life of a Web site is somewhat more than two years. That is to say, an unweeded Web document collection created two years ago would contain the same number of URLs, but only half of those URLs point to content. The second type of change Web documents experience is change in Web page or Web site content. Again based on the Web document samples, very nearly all Web pages and sites undergo some form of content within the period of a year. Some change content very rapidly while others do so infrequently (Koehler, 1999a. This paper examines how Web documents can be efficiently and effectively incorporated into library collections. This paper focuses on Web document lifecycles: persistence, attrition, and intermittence. While the frequency of content change has been reported (Koehler, 1999a, the degree to which those changes effect meaning and therefore the integrity of bibliographic representation is yet not fully understood. The dynamics of change sets Web libraries apart from the traditional library as well as many digital libraries. This paper seeks then to further our understanding of the Web page and Web site lifecycle. These patterns challenge the integrity and the usefulness of libraries with Web content. However, if these dynamics are understood, they can be controlled for or managed.

    Web-based Virtual Tour has become a desirable and demanded application, yet challenging due to the nature of web application's running environment such as limited bandwidth and no guarantee of high computation power on the client side. Image-based rendering approach has attractive advantages over traditional 3D rendering approach in such Web Applications. Traditional geometry-based approach, such as VRML, requires labor-intensive 3D modeling process, high bandwidth and computation power especially for photo-realistic virtual scenes. QuickTime VR and IPIX as examples of image-based approach, use panoramic photos and the virtual scenes that can be generated from photos directly skipping the modeling process. But, QuickTime VR and IPIX may not only require special cameras or effort to take panoramic views but also provide only one fixed-point navigation (look-around and zooming in-out) rather than "walk around", that is a very important feature to provide immersive experience to virtual tourists. Easy and Effective Virtual Tour constructs virtual tour using several snap shots of conventional photos without special tools, build simple 3D space within each photo using spidery mesh, and expand the virtual spaces by connecting each other using simple user intervention to specify correspondence. The expanded virtual space provides virtual tourists with free navigation and immersive experience of walking around through the WWW.

    In the context of world-wide strategies for the reduction of climatic gases the CCS technology (CCS = carbon capture and sequestration) highlights a great importance. In individual areas the capture of carbon dioxide occurs commercially. However, the losses of the efficiency in the operation of power stations must be reduced by the separation and processing of carbon dioxide. A construction of a demonstration unit is particularly important. On this basis, diaphragm-based procedures, procedures for oxygen production as well as the dry sorption of carbon dioxide are promising. The technical and chemical utilization of carbon dioxide can offer an interesting approach for the direct reduction of the global emissions of carbon dioxide.

    Last month marked the 20th anniversary of TREF, CERN’s Tripartite Employment Conditions Forum, which held its first meeting on 27 September 1994. TREF was established to provide a forum in which the Management, Council delegations and the staff would be able to have their say on employment conditions at CERN. Its mandate remains “to oversee the collection of information [about employment conditions at other employers] and to stimulate communication and discussion between representatives of the Member States, the CERN Management and the CERN Staff Association”.   TREF was preceded by a series of bodies, the first of which was established as far back as 1979, the year in which the concept of a five-yearly review of employment conditions was first introduced at CERN. Fifteen years later, the establishment of TREF marked a coming of age. TREF brought a new methodology to data collection activities, systematically looking at the employers that are CERN’s real co...

  8. Gravitation: Following the Prague Inspiration A Volume in Celebration of the 60th Birthday of Jiri Bicak

    Energy Technology Data Exchange (ETDEWEB)

    Griffiths, Jerry

    2003-10-21

    To a relativist, a time period equivalent to that of 60 orbits of the Earth around the Sun, or 5.676438379482{center_dot}10{sup 19} cm of proper time, may not sound particularly significant. Yet, in our human society, it gives us the opportunity of honouring those we love and respect. Such was the occasion for the publication of this volume in honour of Professor Jiri Bicak of the Institute of Theoretical Physics at Charles University in Prague - a city in which Tycho Brahe and Kepler worked together, and where Einstein struggled to construct his general theory of relativity. An appropriate, but unusual, celebratory event which was organized on the relevant January evening involved an intersection of interesting time-shifted worldlines. A record of this is available at http://astro.troja.mff.cuni.cz/bicak/, which may help in comprehending the preface. Our purpose here, however, is to comment on the more permanent item that was produced for the occasion. It must immediately be stated that this is not a typical festschrift in which leading authorities around the world contribute articles dedicated to an academic colleague. It was a surprise present from past research students to their teacher. It maintains the character of a personal tribute but, basically, the contributions are research papers of the highest quality. The result is a very valuable academic reference. As Bicak would have wanted, this is a substantial contribution to objective science, not a piece of post-modern sentimentalism. Reflecting Bicak's own wide interests, the different contributions to this volume cover specific topics in general relativity, astrophysics, theoretical physics and cosmology. They include original articles and thorough up-to-date reviews. In all cases, detailed mathematical or computational analysis is guided by requirements of physical significance. The first paper is by Dolezel on observations from within slowly rotating voids in cosmological models and their

    2007-01-01

    This book containing 30 articles written by highly reputed experts is dedicated to K. Alex Müller on the occasion of his 80th birthday. The contributions reflect the major research areas of K. Alex Müller which he activated in high temperature superconductivity and phase transitions. They are theoretical as well as experimental ones and focus mainly on high temperature superconductivity. A smaller part deals with ferroelectricity and their applications. Also in this field there have recently been major break throughs experimentally as well as theoretically which will be addressed by the invited authors. During the scientific career of K. Alex Müller he made major advances in the understanding of ferroelectricity, which used to be his major research field. The discovery of superconductivity in cuprates for which he received together with J. Georg Bednorz the Nobel Prize in 1987 has not diminished his interest in this area, but has enlarged his activities considerably.

  15. Looking for Darwin's footprints in the microbial world

    Energy Technology Data Exchange (ETDEWEB)

    Shapiro, B. Jesse; David, Lawrence A.; Friedman, Jonathan; Alm, Eric J.

    2009-03-30

    As we observe the 200th anniversary of Charles Darwin's birthday, microbiologists interested in the application of Darwin's ideas to the microscopic world have a lot to celebrate: an emerging picture of the (mostly microbial) Tree of Life at ever-increasing resolution, an understanding of horizontal gene transfer as a driving force in the evolution of microbes, and thousands of complete genome sequences to help formulate and refine our theories. At the same time, quantitative models of the microevolutionary processes shaping microbial populations remain just out of reach, a point that is perhaps most dramatically illustrated by the lack of consensus on how (or even whether) to define bacterial species. We summarize progress and prospects in bacterial population genetics, with an emphasis on detecting the footprint of positive Darwinian selection in microbial genomes.

    @@ Knowledge of the stress field in the Earth's crust is a key issue for the understanding of geodynamic processes,seismic hazard assessment, and stability of underground openings such as waste disposals, tunnels, mines or wells, and reservoir management. The World Stress Map project is a collaborative project of academia,industry and governmental organizations that aims to understand the states and sources of tectonic stresses in the Earth's crust. We present the Worm Stress Map at 1:46,000,000 scale as a result of more than two decades of international collaboration. The map reveals that the first-order pattern of stress is of plate-wide scale, indicating that plate boundary forces are the major control of the stress orientations and the tectonic regime.

  20. Antiretrovirals for developing world.

    1998-01-24

    The most recent UNAIDS figures indicate that approximately 30 million people are infected with HIV worldwide, 5.8 million of whom were newly infected during 1997. At the 10th International Conference on AIDS and Sexually Transmitted Diseases in Africa, the President and Secretary of Health of France called upon developed countries to establish a Therapeutic Assistance Fund to make antiretrovirals available to people with HIV/AIDS in sub-Saharan Africa. While the annual per capita health budget in most African countries is less than US$10, triple antiretroviral therapy against AIDS in the developed world costs $12,000-14,000 per patient per year. Calculations based upon a lower per patient cost of $7000, and treating all 1.4 million African AIDS cases, would cost US$10 billion per year for drugs alone, more than 30 times the amount currently spent annually by international donors for AIDS programs in the entire developing world. Basic infrastructural requirements would have to be met were antiretrovirals made widely available, ranging from HIV screening and counseling to the provision of clean water with which to consume the required 20-30 tablets per day. High program costs will challenge long-term sustainability. Universal access to care and treatment for HIV infection and AIDS is not a reality in the developed world, let alone feasible in developing countries. Given the competing health care priorities in developing countries, the high costs of antiretroviral agents, poor infrastructure, and inability to sustain such a program, the French initiative is ill-advised and foolish public health practice.

    This special issue of Journal of Physics A: Mathematical and Theoretical collects papers by speakers and participants of the conference `Viewing the World through Spin Glasses', held in Oxford (UK) on 31 August and 1 September 2007 in honour of Professor David Sherrington. It also includes contributions by many other active researchers in the field of spin glasses and related problems. The theory of spin glasses has a history of more than 30 years and continues to develop within itself as well as into an unexpectedly vast range of interdisciplinary subjects, including neural networks, error-correcting codes, optimization problems and social problems. Most of these amazing developments have their formal basis in the ground-breaking work of David Sherrington with Scott Kirkpatrick, centred on the SK model and the techniques devised to analyse it via the replica method. In this 'classic-of-classics' paper, a theoretical paradigm was suddenly established which became the common tool of analysis for thousands of papers in the following decades. It also led to deep developments in probability theory, through the efforts to understand the enigmatic Parisi solution of the SK model. The work of Professor Sherrington will continue to be an infinite source of our inspiration in many years to come. The purpose of the conference `Viewing the World through Spin Glasses' was to provide an overview of the present status of the fields which Professor Sherrington initiated, on the occasion of his 65th birthday, organized by John Cardy, Juan P Garrahan and the present Guest Editors. The first contribution in this special issue, by Professor Paul Goldbart, reflects his salute delivered at the conference dinner, and conveys its atmosphere very well. The papers that follow, ordered by the date of acceptance, represent the current activities of leading researchers in spin glasses and related fields, and we expect these to serve as milestones for future developments.

    Symmetry of the world trade network provides a novel perspective to understand the world-wide trading system. However, symmetry in the world trade network (WTN) has been rarely studied so far. In this paper, the authors systematically explore the symmetry in WTN. The authors construct WTN in 2005 and explore the size and structure of its automorphism group, through which the authors find that WTN is symmetric, particularly, locally symmetric to a certain degree. Furthermore, the authors work out the symmetric motifs of WTN and investigate the structure and function of the symmetric motifs, coming to the conclusion that local symmetry will have great effect on the stability of the WTN and that continuous symmetry-breakings will generate complexity and diversity of the trade network. Finally, utilizing the local symmetry of the network, the authors work out the quotient of WTN, which is the structural skeleton dominating stability and evolution of WTN.

Goddard reported on his rocket experiments. Altogether different from the publications just mentioned was a book entitled "Die Erreichbarkeit der Himmelskörper" (The Attainability of Celestial Bodies) published in 1925. Its author was Dr.-Ing. Walter Hohmann, born 18 March 1880, civil engineer for the city authorities of Essen, who had already made, during World War I, calculations as to the amount of fuel, initial mass and flight time necessary for flights from the Earth to other planets. The transfer trajectories investigated by Hohmann and today attributed with his name have a great practical significance for space flight onto the present. In the lecture a critical appreciation of Hohmann's work is given.

    Full Text Available Objective: In July 2012, an outbreak of Campylobacter infection was investigated by the South Australian Communicable Disease Control Branch and Food Policy and Programs Branch. The initial notification identified illness at a surprise birthday party held at a restaurant on 14 July 2012. The objective of the investigation was to identify the potential source of infection and institute appropriate intervention strategies to prevent further illness.Methods: A guest list was obtained and a retrospective cohort study undertaken. A combination of paper-based and telephone questionnaires were used to collect exposure and outcome information. An environmental investigation was conducted by Food Policy and Programs Branch at the implicated premises.Results: All 57 guests completed the questionnaire (100% response rate, and 15 met the case definition. Analysis showed a significant association between illness and consumption of chicken liver pâté (relative risk: 16.7, 95% confidence interval: 2.4–118.6. No other food or beverage served at the party was associated with illness. Three guests submitted stool samples; all were positive for Campylobacter. The environmental investigation identified that the cooking process used in the preparation of chicken liver pâté may have been inconsistent, resulting in some portions not cooked adequately to inactivate potential Campylobacter contamination.Discussion: Chicken liver products are a known source of Campylobacter infection; therefore, education of food handlers remains a high priority. To better identify outbreaks among the large number of Campylobacter notifications, routine typing of Campylobacter isolates is recommended.

He did his PhD degree under Professor Zaleski supervision in 1938 at Jan Kazimierz University. At that time he concentrated his scientific activity on research on tuberculosis. In 1953 he obtained the title of second degree specialist in ear, nose and throat diseases. He became a chief of Otolaryngology at Urban Hospital No 4 in Katowice in 1960. Since then this eminent physician was working on tumours located in upper respiratory tract and the possibility of its endoscopic diagnosis at Silesian Academy of Medicine in Katowice. As one of the first he pointed out the negative influence of smoking cigarettes on cancer of larynx. It was Wacław Kuśnierczyk who implemented new priorities for integrated programs in patient care, research, education and cancer prevention. He has published widely in peer reviewed journals and has edited or contributed to many books. He has given many major lectures and is the recipient of numerous prestigious awards for his scientific accomplishments. The achievement of Professor Kuśnierczyk were the valuable source of information for the physicians. In 1997, on the 31st of January he died in Katowice.

Ding Yifan,Deputy Director of the Institute of World Development under the Development Research Center of the State Council,has made clear China’s growing impact on the global economy.However,as Ding wrote to the Global Times,a Beijing-based daily publication,the knockdown effect of the mortgage crisis is apparent,and emerging markets look even more vulnerable because of it.Excerpts follow:

    We investigate the nature of objects in a complete sample of 28 galaxies selected from the first sky area fully covered by ALFALFA, being well-detected and having HI profiles wider than 550 km/s. The selection does not use brightness, morphology, or any other property derived from optical or other spectral bands. We investigate the degree of isolation, the morphology, and other properties gathered or derived from open data bases and show that some objects have wide HI profiles probably because they are disturbed or are interacting, or might be confused in the ALFALFA beam. We identify a sub-sample of 14 galaxies lacking immediate interacting neighbours and showing regular, symmetric, two-horned HI profiles that we propose as candidate high-mass disk systems (CHMDs). We measure the net-Halpha emission from the CHMDs and combine this with public multispectral data to model the global star formation (SF) properties of each galaxy. The Halpha observations show SFRs not higher than a few solar masses per year. Sim...
