  2. Photosynthesis, environmental change, and plant adaptation: Research topics in plant molecular ecology. Summary report of a workshop

    NONE

    1995-07-01

    As we approach the 21st Century, it is becoming increasingly clear that human activities, primarily related to energy extraction and use, will lead to marked environmental changes at the local, regional, and global levels. The realized and the potential photosynthetic performance of plants is determined by a combination of intrinsic genetic information and extrinsic environmental factors, especially climate. It is essential that the effects of environmental changes on the photosynthetic competence of individual species, communities, and ecosystems be accurately assessed. From October 24 to 26, 1993, a group of scientists specializing in various aspects of plant science met to discuss how our predictive capabilities could be improved by developing a more rational, mechanistic approach to relating photosynthetic processes to environmental factors. A consensus emerged that achieving this goal requires multidisciplinary research efforts that combine tools and techniques of genetics, molecular biology, biophysics, biochemistry, and physiology to understand the principles, mechanisms, and limitations of evolutional adaptation and physiological acclimation of photosynthetic processes. Many of these basic tools and techniques, often developed in other fields of science, already are available but have not been applied in a coherent, coordinated fashion to ecological research. The efforts of this research program are related to the broader efforts to develop more realistic prognostic models to forecast climate change that include photosynthetic responses and feedbacks at the regional and ecosystem levels.

    2014-07-01

    Full Text Available In this study, we used the approach of topic modeling to uncover the possible structure of research topics in the field of Informetrics, to explore the distribution of the topics over years, and to compare the core journals. In order to infer the structure of the topics in the field, the data of the papers published in the Journal of Informetricsand Scientometrics during 2007 to 2013 are retrieved from the database of the Web of Science as input of the approach of topic modeling. The results of this study show that when the number of topics was set to 10, the topic model has the smallest perplexity. Although data scopes and analysis methodsare different to previous studies, the generating topics of this study are consistent with those results produced by analyses of experts. Empirical case studies and measurements of bibliometric indicators were concerned important in every year during the whole analytic period, and the field was increasing stability. Both the two core journals broadly paid more attention to all of the topics in the field of Informetrics. The Journal of Informetricsput particular emphasis on construction and applications ofbibliometric indicators and Scientometrics focused on the evaluation and the factors of productivity of countries, institutions, domains, and journals.

  18. A method of detecting emerging trends in research topics

    Fei; GE; Zongying; TAN

    2014-01-01

    Purpose:This paper proposes a method of detecting emerging trends in research topics from a more micro perspective.Design/methodology/approach:Through co-word clustering to identify research topics and analyzing position changes of topic words in the keywords life-cycle diagram during different time periods,we detected emerging trends in research topics from a more micro perspective.I’he method was applied to the field of nanotechnology to verify its effectiveness and practicability.Findings:The results show that this method can be used to detect emerging trends in research topics from a more micro perspective,as it divides keywords into five categories:Potential keywords,emerging keywords,hot keywords,stable keywords and recession keywords,through which more details of topic changes can be found.Research limitations:We used keywords provided by authors and database indexers for keywords extraction.But this approach may lead to the problem of "indexer effect".The method may have a limited effect when applied to a disciplinary domain such as mathematics,which evolves slowly.Practical implications:This study provides information analysts with insights into the way to better understand specialty areas of a discipline domain and formulate research policies and strategic plans.Originality/value:This study contributes to the current literature by proposing a new method,which can detect emerging trends in research topics from a more micro perspective.

  4. A TEXT MINING RESEARCH BASED ON LDA TOPIC MODELLING

    Zhou Tong

    2016-05-01

    Full Text Available A Large number of digital text information is generated every day. Effectively searching, managing and exploring the text data has become a main task. In this paper, we first represent an introduction to text mining and a probabilistic topic model Latent Dirichlet allocation. Then two experiments are proposed - Wikipedia articles and users’ tweets topic modelling. The former one builds up a document topic model, aiming to a topic perspective solution on searching, exploring and recommending articles. The latter one sets up a user topic model, providing a full research and analysis over Twitter users’ interest. The experiment process including data collecting, data pre-processing and model training is fully documented and commented. Further more, the conclusion and application of this paper could be a useful computation tool for social and business research.

The book examines how RESTful systems can be designed and deployed, and what the results are in terms of benefits and challenges encountered in the process. This book is intended for information and service architects and designers who are interested in learning about REST, how it is applied, and how it is being advanced.

  7. Adaptation to heat and exercise performance under cooler conditions: a new hot topic.

    Corbett, Jo; Neal, Rebecca A; Lunt, Heather C; Tipton, Michael J

    2014-10-01

    Chronic exposure to a stressor elicits adaptations enhancing the tolerance to that stressor. These adaptive responses might also improve tolerance under less stressful conditions. For example, historically there has been much interest in the adaptive responses to high-altitude, or hypoxia, and their ergogenic potential under sea-level, or normoxic, conditions. In contrast, the influence of the adaptive responses to heat on exercise under cooler conditions has received relatively little interest. Heat acclimation/acclimatization (HA) is known to increase work capacity in hot environments. Yet, aerobic exercise performance can progressively deteriorate as ambient temperature increases beyond ~10 °C, indicating a thermal limitation even under relatively cool conditions. The improved thermoregulatory capability induced by HA might attenuate this thermal decrement in a manner similar to that seen when exposed to hotter temperatures. Moreover, the suite of adaptations elicited by HA has the potential to increase maximal oxygen uptake, lactate threshold and economy, and thus may be ergogenic even under conditions where performance is not thermally limited. Indeed, evidence is now emerging to support an ergogenic effect of HA but the number of studies is limited and in some instances lack appropriate control, are confounded by methodological limitations, or do not address the mechanisms of action. Nevertheless, these tantalising insights into the ergogenic potential of heat will likely generate considerable interest in this new 'hot topic'. Future research will need to employ well-designed studies to clarify the exercise conditions under which ergogenic effects of HA are apparent, to elucidate the precise mechanisms, and to optimise HA strategies for performance.

  11. Characterizing interdisciplinarity of researchers and research topics using web search engines.

    Sayama, Hiroki; Akaishi, Jin

    2012-01-01

    Researchers' networks have been subject to active modeling and analysis. Earlier literature mostly focused on citation or co-authorship networks reconstructed from annotated scientific publication databases, which have several limitations. Recently, general-purpose web search engines have also been utilized to collect information about social networks. Here we reconstructed, using web search engines, a network representing the relatedness of researchers to their peers as well as to various research topics. Relatedness between researchers and research topics was characterized by visibility boost-increase of a researcher's visibility by focusing on a particular topic. It was observed that researchers who had high visibility boosts by the same research topic tended to be close to each other in their network. We calculated correlations between visibility boosts by research topics and researchers' interdisciplinarity at the individual level (diversity of topics related to the researcher) and at the social level (his/her centrality in the researchers' network). We found that visibility boosts by certain research topics were positively correlated with researchers' individual-level interdisciplinarity despite their negative correlations with the general popularity of researchers. It was also found that visibility boosts by network-related topics had positive correlations with researchers' social-level interdisciplinarity. Research topics' correlations with researchers' individual- and social-level interdisciplinarities were found to be nearly independent from each other. These findings suggest that the notion of "interdisciplinarity" of a researcher should be understood as a multi-dimensional concept that should be evaluated using multiple assessment means.

  15. Research on Online Topic Evolutionary Pattern Mining in Text Streams

    Qian Chen

    2014-06-01

    Full Text Available Text Streams are a class of ubiquitous data that came in over time and are extraordinary large in scale that we often lose track of. Basically, text streams forms the fundamental source of information that can be used to detect semantic topic which individuals and organizations are interested in as well as detect burst events within communities. Thus, intelligent system that can automatically extract interesting temporal pattern from text streams is terribly needed; however, Evolutionary Pattern Mining is not well addressed in previous work. In this paper, we start a tentative research on topic evolutionary pattern mining system by discussing fully properties of a topic after formally definition, as well as proposing a common and formal framework in analyzing text streams. We also defined three basic tasks including (1 online topic Detection, (2 event evolution extraction and (3 topic property life cycle, and proposed three common mining algorithms respectively. Finally we exemplify the application of Evolutionary Pattern Mining and shows that interesting patterns can be extracted in newswire dataset

  16. Novelty Detection via Topic Modeling in Research Articles

    S. Sendhilkumar

    2013-05-01

    Full Text Available In today’s world redundancy is the most vital probl em faced in almost all domains. Novelty detection is the identification of new or unknown d ata or signal that a machine learning system is not aware of during training. The problem become s more intense when it comes to “Research Articles”. A method of identifying novelty at each sections of the article is highly required for determining the novel idea proposed in the research paper. Since research articles are semi- structured, detecting novelty of information from t hem requires more accurate systems. Topic model provides a useful means to process them and p rovides a simple way to analyze them. This work compares the most predominantly used topic mod el- Latent Dirichlet Allocation with the hierarchical Pachinko Allocation Model. The results obtained are promising towards hierarchical Pachinko Allocation Model when used fo r document retrieval.

  17. Radiation and lung cancer: problems and topics of future research

    It was the purpose of this critical review to outline the main uncertainties of present risk estimates for radiation-induced lung cancer and the resulting topics of future research in this field. The main emphasis was the actual problems of dose and risk estimates for indoor exposure to radon daughters. The discussion indicates that the conclusions of the ICRP and the BEIR IV studies, which proceed from data of radon-exposed miners, are based on models and assumptions that are too simple. Comparison with the lung cancer data from the atomic bomb survivors indicates that these uncertainties concern mainly the transfer of the data from male miners to the female population and the influence of smoking. This underlines the importance of large direct case-control studies on lung cancer from indoor radon. A detailed list of topics for future research in this field is presented in the summary of this session. (author)

  10. Research Priorities on Vulnerability, Impacts and Adaptation: Responding to the Climate Change Challenge

    Rosenzweig, C.; Horton, R. M.

    2013-12-01

    A major challenge of the research community is to provide relevant information to policymakers on vulnerability, impacts and adaptation (VIA) in the context of a changing climate, and to do so in a coherent and coordinated way. The Programme of Research on Climate Change Vulnerability, Impacts and Adaptation (PROVIA) aims to respond to this challenge by harmonizing, mobilizing, and communicating the growing knowledgebase on VIA to relevant audiences. PROVIA, in consultation with experts and policymakers, has developed a set of Research Priorities for the global VIA research community, whose activities are primarily carried out by individual researchers and research institutions. The Research Priorities include new and emerging topics as well as topics that have long been recognized as important but for which research is still required. To develop the Research Priorities, input was gathered from expert and policymaker communities through separate solicitation pathways. The expert prioritization of research topics began with a gap analysis based on existing literature. The members of the PROVIA Scientific Steering Committee (SSC) then participated in a two-day Foresight Panel that focused on determining selection criteria for inclusion in the Research Priorities, grouping the research topics into themes, and identifying additional topics. A newly framed list of 54 priority research topics was generated by compiling the SSC selections and updated findings from new literature. This list was distributed as an electronic survey to a broad group of experts in the VIA community. Respondents were asked to score each topic, provide suggestions for additional topics, and offer comments. A research prioritization process with policymakers was developed in parallel with the expert community process described above and included representatives from both developed and developing countries. The rankings of the expert and policymaker processes were then combined, along with an

  11. An Adaptive Updating Topic Specific Web Search System Using T-Graph

    Ahmed Patel

    2010-01-01

    Full Text Available Problem statement: The main goal of a Web crawler is to collect documents that are relevant to a given topic in which the search engine specializes. These topic specific search systems typically take the whole document's content in predicting the importance of an unvisited link. But current research had proven that the document's content pointed to by an unvisited link is mainly dependent on the anchor text, which is more accurate than predicting it on the contents of the whole page. Approach: Between these two extremes, it was proposed that Treasure Graph, called T-Graph is a more effective way to guide the Web crawler to fetch topic specific documents predicted by identifying the topic boundary around the unvisited link and comparing that text with all the nodes of the T-Graph to obtain the matching node(s and calculating the distance in the form of documents to be downloaded to reach the target documents. Results: Web search systems based on this strategy allowed crawlers and robots to update their experiences more rapidly and intelligently that can also offer speed of access and presentation advantages. Conclusion/Recommendations: The consequences of visiting a link to update a robot's experiences based on the principles and usage of T-Graph can be deployed as intelligent-knowledge Web crawlers as shown by the proposed novel Web search system architecture.

  12. Research recommendations of the ESA Topical Team on Artificial Gravity

    Clément, Gilles; Bukley, Angie

    Many experts believe that artificial gravity will be required for an interplanetary mission. However, despite its attractiveness as an efficient, multi-system countermeasure and its potential for simplifying operational activities, much still needs to be learned regarding the human response to rotating environments before artificial gravity can be successfully implemented. The European Space Agency (ESA) Topical Team on Artificial Gravity recommended a comprehensive program to determine the gravity threshold required to reverse or prevent the detrimental effects of microgravity and to evaluate the effects of centrifugation on various physiological functions. Part of the required research can be accomplished using animal models on a dedicated centrifuge in low Earth orbit. Studies of human responses to centrifugation could be performed during ambulatory, short- and long-duration bed rest, and in-flight studies. Artificial-gravity scenarios should not be a priori discarded in Moon and Mars mission designs. One major step is to determine the relationship between the artificial gravity dose level, duration, and frequency and the physiological responses of the major body functions affected by spaceflight. Once its regime characteristics are defined and a dose-response curve is established, artificial gravity should serve as the standard against which all other countermeasure candidates are evaluated, first on Earth and then in space.

  3. Research Trends in Adapted Physical Activity Quarterly From 2004 to 2013.

    Haegele, Justin A; Lee, Jihyun; Porretta, David L

    2015-07-01

    The purpose of this documentary analysis was to examine trends in research published in Adapted Physical Activity Quarterly (APAQ) over a 10-yr span. A total of 181 research articles published from 2004 to 2013 were coded and analyzed using the following categories: first-author country affiliation, theoretical framework, intervention, research methods, disability categories, and topical focus. Results indicate high frequencies of nonintervention and group-design studies, as well as a low frequency of studies that describe a theoretical or conceptual framework. Trends in disability of participants and topical focus reflect current interests of researchers publishing in APAQ. While some scholars have suggested that changes in research on adapted physical activity would occur, the results of this analysis suggest that many of these categories remain largely unchanged for research published in APAQ. This study calls attention to similarities between the results of the current analysis and previous ones. PMID:26113549

  11. Topical advances and recent studies in paleolimnological research

    Thomas J. Whitmore

    2014-04-01

    Full Text Available Paleolimnology combines the disciplines of limnology, geology and ecology, but because of challenges that separate investigators from direct knowledge about past lake conditions, the field is multidisciplinary by necessity. As a result, paleolimnology is influenced continuously by advances in many disciplines. As with limnological studies in recent decades, paleolimnology has diverged largely from the ecological and theoretical focuses of early investigators, but recent studies demonstrate the need for more integration of ecological and paleolimnological research. This paper provides a brief overview of recent paleolimnological investigations that have addressed questions related to theoretical ecology, as well as applied lake-management and climate research issues. We examine the use of transfer function models for estimating past water-quality conditions, and important caveats expressed by investigators about limitations in the development and use of such models. Paleolimnological research has contributed new insights about biological, physical and chemical processes in lakes that have been subject to change because of climate drivers and anthropogenic influences. These findings are relevant to predicting how lakes will respond to climate change, and will require new management approaches in the future. As the range of paleolimnological studies expands, there will be greater need for basic limnological research in order for paleolimnological investigators to better understand how sediments reflect lake processes of those regions.

  12. Selected topics in research program on IBR-2

    The physical start-up of the IBR-2 fast pulsed reactor took place in the Laboratory of Neutron Physics, Joint Institute for Nuclear Research, USSR. Design values for instantaneous thermal neutron fluxes are: 10/sup 17/ cm/sup -2/s/sup -1/ inside the moderator and 10/sup 16/ cm/sup -2/ s/sup -1/ from its surface. In combination with the heavy current, short pulse injector (electron induction accelerator LIU-30 being under construction now), it will become a high intensity neutron source for the time-of-flight investigations in the energy range from 10/sup -7/ to 10/sup 6/ ev. The characteristics of the complex IBR-2+LIU-30 2+are described. The neutron beams and their use in the condensed matter and applied research are mentioned. The program for n/alpha/-, n/gamma/-and nf- cross section measurements as well as neutron cross section study for few nucleon systems are reported. The prospects for nuclear physics research on the LIU-30 non-multiplying target facility are outlined using as examples the experiments with polarized neutrons and nuclei and some others. The description is illustrated with the results obtained recently on the operating IBR-30 pulsed reactor. 40 refs

  13. Development of a topic-related sentence corpus for speech perception research

    Helfer, Karen S.; Freyman, Richard L.

    2001-05-01

    A large sentence corpus has been developed for use in speech recognition research. Sentences (n=881, three scoring words per sentence) were developed under 23 topics. In the first phase of development subjects rated each individual scoring word for relatedness to its given topic on a Likert scale. Next, two groups of young, normal-hearing listeners (n=16/group) listened and responded to the recordings of the sentences (spoken by a female talker) presented with one of two types of maskers: steady-state noise (S:N=-13 dB) or two other females speaking random sentences (S:N=-8 dB). Each subject responded to half of the sentences with topic supplied and half with no topic supplied. Data analyses focused on addressing two questions: whether supplementation of topic would be more important in the presence of the speech masker versus the noise masker, and how the degree of relatedness of each key word to the topic influenced the effect of topic on recognition. The data showed little difference in how beneficial the topic was for speech versus noise maskers. Moreover, there was a complex relationship between effect of topic, type of masker, and position of the word in the sentence. [Work supported by NIDCD DC01625.

  14. Proceedings of International Topical Meeting on Nuclear Research Applications and Utilization of Accelerators

    The IAEA has responded to Member States needs by implementing programmatic activities that provide interested Member States, particularly those in developing countries, forums to exchange information on new trends and applications in accelerator-based nuclear science and technology. Accelerator-based technologies are regarded by many Member States as a key element to serve social and economic development in a wide variety of applications in the energy, health, agriculture, environment, materials, natural resources and education sectors. Almost all of the more than 18 000 particle accelerators in the world today are dedicated machines used for commercial applications, being either in the medical sector (radiotherapy treatments) or in the industrial sector (materials modification). Only a few percent (a few hundred) of the worldwide inventory of accelerators is used for scientific research, mainly at universities, research institutes and international organizations. However, the knowledge and technological spin-offs gained from these research accelerators drive the development of commercial applications and support the research and development needs of researchers in a wide and diverse range of fields, including strategic and applied research, safety and security, environment, materials, analytical services, advanced nuclear fuel cycles, radioisotope production and radiation processing. The ongoing benefits afforded by accelerators derive principally from their ability to adapt to and keep pace with evolving changes in user demands. The trend in advanced countries is to utilize accelerators in a dedicated and optimized way to support a few specific high technology application areas. The main demand from researchers is for high quality X ray, neutron and ion beams to engage in cutting-edge research in energy, food and agriculture, biology, medicine and materials science. The enhancement of nuclear science education and research in all Member States, but in particular

    2016-02-01

    The 2015 United Nations Climate Change Conference in Paris (COP21) highlighted the importance of cities to climate action, as well as the unjust burdens borne by the world's most disadvantaged peoples in addressing climate impacts. Few studies have documented the barriers to redressing the drivers of social vulnerability as part of urban local climate change adaptation efforts, or evaluated how emerging adaptation plans impact marginalized groups. Here, we present a roadmap to reorient research on the social dimensions of urban climate adaptation around four issues of equity and justice: (1) broadening participation in adaptation planning; (2) expanding adaptation to rapidly growing cities and those with low financial or institutional capacity; (3) adopting a multilevel and multi-scalar approach to adaptation planning; and (4) integrating justice into infrastructure and urban design processes. Responding to these empirical and theoretical research needs is the first step towards identifying pathways to more transformative adaptation policies.

  2. Adaptive Sensor Optimization and Cognitive Image Processing Using Autonomous Optical Neuroprocessors; TOPICAL

    Measurement and signal intelligence demands has created new requirements for information management and interoperability as they affect surveillance and situational awareness. Integration of on-board autonomous learning and adaptive control structures within a remote sensing platform architecture would substantially improve the utility of intelligence collection by facilitating real-time optimization of measurement parameters for variable field conditions. A problem faced by conventional digital implementations of intelligent systems is the conflict between a distributed parallel structure on a sequential serial interface functionally degrading bandwidth and response time. In contrast, optically designed networks exhibit the massive parallelism and interconnect density needed to perform complex cognitive functions within a dynamic asynchronous environment. Recently, all-optical self-organizing neural networks exhibiting emergent collective behavior which mimic perception, recognition, association, and contemplative learning have been realized using photorefractive holography in combination with sensory systems for feature maps, threshold decomposition, image enhancement, and nonlinear matched filters. Such hybrid information processors depart from the classical computational paradigm based on analytic rules-based algorithms and instead utilize unsupervised generalization and perceptron-like exploratory or improvisational behaviors to evolve toward optimized solutions. These systems are robust to instrumental systematics or corrupting noise and can enrich knowledge structures by allowing competition between multiple hypotheses. This property enables them to rapidly adapt or self-compensate for dynamic or imprecise conditions which would be unstable using conventional linear control models. By incorporating an intelligent optical neuroprocessor in the back plane of an imaging sensor, a broad class of high-level cognitive image analysis problems including geometric

  3. Confronting international research topics with stakeholders on multifunctional land use: the case of Inner Mongolia, China

    König HJ

    2014-12-01

    Full Text Available The established pattern of land use in the Inner Mongolia Autonomous Region is being challenged by China’s rapid overall economic transition. The provision of required land-related functions and services is subject to land management decision making. Scientific research can offer substantial support for this decision making by providing evidence of the interaction between land management and land function services. This paper’s objective was to identify the most important land use functions and services from a local perspective and to compare these functions and services with the land-related research topics addressed in the scientific literature. For this purpose, we conducted a workshop with local stakeholders (land use decision makers in the West Ujimqin Banner (Inner Mongolia as a specific case study and performed a comprehensive survey of the Inner Mongolian land use research published in international scientific journals. Our analysis indicated that the stakeholders assigned particular importance to social land use functions, such as jobs, as well as environmental land use functions and ecosystem processes. In contrast, the research topics were primarily concerned with natural science. We discussed possible shortcomings in the research agenda by emphasising and contrasting local stakeholder perspectives with the research topics and concluded that without bottom-up stakeholder participation, there would be a mismatch between the research interests of land use scientists and the needs of stakeholders. Future research that can contribute to local policy making with the aim of meeting the objectives of a multifunctional land use concept is required.

    Volpentesta, Antonio P.; Felicetti, Alberto M.

    2010-01-01

    In this paper we propose a weighted multi-hypergraph as logical structure to model relationships between researchers and interest groups that join them on the base of shared research topics in a given scientific community. The well known concept of eingenvector centrality for graphs is extended to weighted multi-hypergraphs and we present a model instantiation for centrality analysis in the Pro-VE scientific community.

    2006-01-01

    Adaptive Modulation and Coding (AMC) has gained a lot of attentions in the research of High Speed Downlink Packet Access (HSDPA). The idea is to adapt the transmission to the fast changing channel conditions by the use of different Modulation and Coding Schemes (MCS). This paper presents an adaptive AMC algorithm and introduces a theoretical analysis model in order to to investigate its throughput and Frame Error Rate (FER). Subject to the given FER target, our numerical and link level simulation results both show that our algorithm outperforms other existing adaptive algorithms.

  11. Teachers, Mentors, Researchers, Popularizers, Publicists and Their Publications on Educational Topics [In Bulgarian

    B.V. Toshev

    2009-06-01

    Full Text Available There are two professions in education – teachers who do it and researchers who study it. Teachers and researchers both write papers but those papers are quite different. In addition there exist other people who attempt to write on educational topics: mentors, involved in teachers training, popularizers of science, publicists. The paper stresses in the peculiarities of these literature works. The problems of the professional identification of teachers and educational researchers are also considered in detail. Who is the successful teacher, who is the successful researcher – the paper gives answers of such questions.

  12. Towards a research agenda for adapting to climate change

    The views, publications and research related to building design and climate change are reviewed in generic terms at the outset of this paper in order to identify a number of questions and potential research avenues. In particular, the links between the roles of building design and its implications for occupant behaviour are addressed in the context of the environmental performance of buildings and climate change. The emphasis is on the integration of adaptation with energy-efficient design, both in terms of how buildings can be designed to increase their adaptive potential and of the significance of occupant adaptive opportunities.

  13. Adaptive forward-inverse modeling of reservoir fluids away from wellbores; TOPICAL

    This Final Report contains the deliverables of the DeepLook Phase I project entitled, ''Adaptive Forward-Inverse Modeling of Reservoir Fluids Away from Wellbores''. The deliverables are: (i) a description of 2-D test problem results, analyses, and technical descriptions of the techniques used, (ii) a listing of program setup commands that construct and execute the codes for selected test problems (these commands are in mathematical terminology, which reinforces technical descriptions in the text), and (iii) an evaluation and recommendation regarding continuance of this project, including considerations of possible extensions to 3-D codes, additional technical scope, and budget for the out-years. The far-market objective in this project is to develop advanced technologies that can help locate and enhance the recovery of oil from heterogeneous rock formations. The specific technical objective in Phase I was to develop proof-of-concept of new forward and inverse (F-I) modeling techniques[Gelinas et al, 1998] that seek to enhance estimates (images) of formation permeability distributions and fluid motion away from wellbore volumes. This goes to the heart of improving industry's ability to jointly image reservoir permeability and flow predictions of trapped and recovered oil versus time. The estimation of formation permeability away from borehole measurements is an ''inverse'' problem. It is an inseparable part of modeling fluid flows throughout the reservoir in efforts to increase the efficiency of oil recovery at minimum cost. Classic issues of non-uniqueness, mathematical instability, noise effects, and inadequate numerical solution techniques have historically impeded progress in reservoir parameter estimations. Because information pertaining to fluid and rock properties is always sampled sparsely by wellbore measurements, a successful method for interpolating permeability and fluid data between the measurements must be: (i) physics-based, (ii) conditioned by signal

  14. Adaptive nonlinear control for a research reactor

    Linearization by feedback of states is based on the idea of transform the nonlinear dynamic equation of a system in a linear form. This linear behavior can be achieve well in a complete way (input state) or in partial way (input output). This can be applied to systems of single or multiple inputs, and can be used to solve problems of stabilization and tracking of references trajectories. Comparing this method with conventional ones, linearization by feedback of states is exact in certain region of the space of state, instead of linear approximations of the equations in a certain point of the operation. In the presence of parametric uncertainties in the model of the system, the introduction of adaptive schemes provide a type toughness to the control system by nonlinear feedback, which gives as result the eventual cancellation of the nonlinear terms in the dynamic relationship between the output and the input of the auxiliary control. In the same way, it has been presented the design of a nonlinearizing control for the non lineal model of a TRIGA Mark III type reactor, with the aim of tracking a predetermined power profile. The asymptotic tracking of such profile is, at the present moment, in the stage of verification by computerized simulation the relative easiness in the design of auxiliary variable of control, as well as the decoupling action of the output variable, make very attractive the utilization of the method herein presented.

  18. Selecting their Own Research Topic: An Effective Means of Engaging Undergraduates in Geoscience Careers

    Sloan, V.; Haacker-Santos, R.

    2012-12-01

    Research experiences have been shown to successfully help draw undergraduates into STEM fields. In the SOARS and RESESS summer internship programs, which focus on the atmospheric and Earth sciences respectively, we attempt to match each intern with a project that is of specific interest to them, and to place the student with a science mentor with that expertise. Initially interns are solicited before the summer on their preferred topics of interest by having applicants or reapplicants choose fields of study from a list of topics. Follow-up conversations help to better define their area of interest. We then match those with the projects that have been proposed by prospective mentors, or seek scientists in the community who do research in that subdiscipline. Mentors also evaluate the intern's course background to determine if they have the foundation necessary for that work. Interns report that the opportunity to work on a topic that they perceive as interesting is vital to their engagement in the research. One intern wrote, "One of the most important components of internships like this is definitely letting the students somewhat chose their project. I think that a really good way to turn students OFF from research is by having them spend a summer researching something they are not even close to interested in." Another commented, "I really appreciated being matched with a project in my interest area. I think that's really important, even if it just teaches you that you might want to work in a different field than you initially thought." Being immersed in such a research group or lab provides interns with a rich opportunity to learn relevant content and skills, and to start developing a professional support network. Interns continue to engage with experts in their field of interest when they present at at scientifically relevant meeting sessions during the following academic year. Many of our interns go on to study the same subdiscipline of atmospheric or Earth

  19. Text analysis tools for identification of emerging topics and research gaps in conservation science.

    Westgate, Martin J; Barton, Philip S; Pierson, Jennifer C; Lindenmayer, David B

    2015-12-01

    Keeping track of conceptual and methodological developments is a critical skill for research scientists, but this task is increasingly difficult due to the high rate of academic publication. As a crisis discipline, conservation science is particularly in need of tools that facilitate rapid yet insightful synthesis. We show how a common text-mining method (latent Dirichlet allocation, or topic modeling) and statistical tests familiar to ecologists (cluster analysis, regression, and network analysis) can be used to investigate trends and identify potential research gaps in the scientific literature. We tested these methods on the literature on ecological surrogates and indicators. Analysis of topic popularity within this corpus showed a strong emphasis on monitoring and management of fragmented ecosystems, while analysis of research gaps suggested a greater role for genetic surrogates and indicators. Our results show that automated text analysis methods need to be used with care, but can provide information that is complementary to that given by systematic reviews and meta-analyses, increasing scientists' capacity for research synthesis.

  1. International topical meeting on nuclear research applications and utilization of accelerators. Book of abstracts

    Applications of particle accelerators cover a number of areas, from strategic and applied research, safety and security, environmental applications, materials research and analytical sciences, to radioisotope production and radiation processing. Accelerator based techniques and pulsed neutron sources are expected to lead to new initiatives in materials research of relevance for both the nuclear and non-nuclear fields. Material science studies with the use of accelerators, neutron beams and other nuclear analytical methods are relevant to the development of advanced reactors, nuclear fuel cycle needs and fusion research. In this regard, a better understanding of the irradiation effects in materials for energy and non-energy applications is needed, and is reflected in accelerator techniques for modification and analysis of materials for nuclear technologies. Accelerator applications for innovative nuclear systems aiming at rad-waste transmutation (e.g., accelerator driven systems) are being pursued in many countries. Research and development using accelerators involves a broad spectrum of skills to build a cadre of trained experts in nuclear techniques in IAEA Member States, and to generate knowledge for innovative methodologies and tools. The present conference is also being held in cooperation with the American Nuclear Society (ANS), which successfully organized the series of accelerator applications conferences known as AccApp. The ANS series of topical meetings has provided a forum for the global exchange of scientific and technical knowledge on a wide variety of related topics since the first AccApp took place in 1997 in Albuquerque, USA. The last conference which was held in 2007 in Pocatello, USA, was jointly organized by the ANS and the IAEA. The main objectives of the conference are to promote exchange of information among IAEA Member States representatives/delegates and to discuss new trends in accelerator applications including nuclear materials research

  2. Proceedings of IAERU seminar-VII, 'research works with cold neutrons and the related recent topics'

    The 7th seminar of the Institute for Atomic Energy, Rikkyo University, was held on June 8, 1991, and this is the proceedings of the seminar. The program was arranged centering around the research using cold neutrons and the related recent topics. The true values of research reactors are dependent on how effectively the generated neutrons are utilized, but as for neutrons, many things are still unkown. It was considered that the study on neutrons returning to the original aim may open the new way for the utilization of research reactors, this theme was selected. The mystery of quantum theory and neutrons, neutron lifetime and solar neutrinos, the application of small angle neutron scattering to biological systems, and imaging through inside of materials-cold neutron radiography were the subjects of lectures.

  7. The research and development of the adaptive optics in ophthalmology

    Wu, Chuhan; Zhang, Xiaofang; Chen, Weilin

    2015-08-01

    Recently the combination of adaptive optics and ophthalmology has made great progress and become highly effective. The retina disease is diagnosed by retina imaging technique based on scanning optical system, so the scanning of eye requires optical system characterized by great ability of anti-moving and optical aberration correction. The adaptive optics possesses high level of adaptability and is available for real time imaging, which meets the requirement of medical retina detection with accurate images. Now the Scanning Laser Ophthalmoscope and the Optical Coherence Tomography are widely used, which are the core techniques in the area of medical retina detection. Based on the above techniques, in China, a few adaptive optics systems used for eye medical scanning have been designed by some researchers from The Institute of Optics And Electronics of CAS(The Chinese Academy of Sciences); some foreign research institutions have adopted other methods to eliminate the interference of eye moving and optical aberration; there are many relevant patents at home and abroad. In this paper, the principles and relevant technique details of the Scanning Laser Ophthalmoscope and the Optical Coherence Tomography are described. And the recent development and progress of adaptive optics in the field of eye retina imaging are analyzed and summarized.

  14. The Global Evidence Mapping Initiative: Scoping research in broad topic areas

    Tavender Emma

    2011-06-01

    Full Text Available Abstract Background Evidence mapping describes the quantity, design and characteristics of research in broad topic areas, in contrast to systematic reviews, which usually address narrowly-focused research questions. The breadth of evidence mapping helps to identify evidence gaps, and may guide future research efforts. The Global Evidence Mapping (GEM Initiative was established in 2007 to create evidence maps providing an overview of existing research in Traumatic Brain Injury (TBI and Spinal Cord Injury (SCI. Methods The GEM evidence mapping method involved three core tasks: 1. Setting the boundaries and context of the map: Definitions for the fields of TBI and SCI were clarified, the prehospital, acute inhospital and rehabilitation phases of care were delineated and relevant stakeholders (patients, carers, clinicians, researchers and policymakers who could contribute to the mapping were identified. Researchable clinical questions were developed through consultation with key stakeholders and a broad literature search. 2. Searching for and selection of relevant studies: Evidence search and selection involved development of specific search strategies, development of inclusion and exclusion criteria, searching of relevant databases and independent screening and selection by two researchers. 3. Reporting on yield and study characteristics: Data extraction was performed at two levels - 'interventions and study design' and 'detailed study characteristics'. The evidence map and commentary reflected the depth of data extraction. Results One hundred and twenty-nine researchable clinical questions in TBI and SCI were identified. These questions were then prioritised into high (n = 60 and low (n = 69 importance by the stakeholders involved in question development. Since 2007, 58 263 abstracts have been screened, 3 731 full text articles have been reviewed and 1 644 relevant neurotrauma publications have been mapped, covering fifty-three high priority

  15. Demographic changes and the demands on agricultural landscapes: Refl ections on a new research topic

    K. Müller

    2008-12-01

    Full Text Available Demographic change suggests substantial effects on future societal demands on agricultural landscape use and thus on rural areas. Demographic change is thereby defined as both the decrease of the population and the shift in the age distribution („aging“ and in the spatial distribution („rural flight“ particularly of young people. The exploration of the research object is based on the starting hypothesis that the demands and preferences of an aging and urbanizing population are changing and have effects on the controlling state interventions, which are also reflected in the agricultural use of landscapes. After a short description of demographic change, a conceptual politico-economic model, which describes the transmission of demographic change on land use, through the analysis of group (age groups, groups of residences demands on agrarian landscape use is presented. The focus is on the demand for land use related non-commodity outputs (NCO. The starting hypothesis is then examined using selected studies. The literature suggests that urban-rural dichotomy is likely to be greatly diminished. In addition, the urbanization of preferences is expected while preferences differentiated against heterogeneous cultural lifestyles seem to become even more important. However, without further research on the related topics, the basic issues cannot be clearly dealt with. Assumptions are finally made regarding changing societal demands for agrarian landscapes due to demographic change. The limitations of the selected approach and the identification of further research needs will be discussed in closing.

    2015-04-01

    Topics in Current Science Research (TCSR) is a five-week summer course offered at the University of California, Berkeley through a collaboration between the Level Playing Field Institute's Summer Math and Science Honors Academy (SMASH) Program and the Cryogenic Dark Matter Search (CDMS) group at UC Berkeley. SMASH is an academic enrichment program geared towards under-resourced, high school students of color. The goals of the course are to expand the students' conception of STEM, to teach the students that science is a method of inquiry and not just a collection of facts that are taught in school, and to expose the scholars to critical thinking within a scientific setting. The course's curriculum engages the scholars in hands-on scientific research, project proposal writing, and presentation of their scientific work to their peers as well as to a panel of UC Berkeley scientists. In this talk, we describe the course and the impact it has had on previous scholars, we discuss how the course's pedagogy has evolved over the past 10 years to enhance students' perception and understanding of science, and we present previous participants' reflections and feedback about the course and its success in providing high school students a genuine research experience at the university level.

  17. FILLER ENGINEERING FOR PAPERMAKING: COMPARISION WITH FIBER ENGINEERING AND SOME IMPORTANT RESEARCH TOPICS

    Jing Shen

    2010-05-01

    Full Text Available Fibers and fillers are important raw materials for the preparation of paper products. Similar to fiber engineering, filler engineering for papermaking has become an active research area. There are similarities as well as differences between engineering involving each of these classes of materials. There are differences in such aspects as the nature of materials to be engineered, applicable engineering methods, and engineerablity of the material surfaces. The co-development of fiber engineering and filler engineering can potentially provide many benefits to the papermaking industry. For filler engineering, the relevant research topics broadly can include fibrous filler engineering, hollow/porous filler engineering, acid-stabilization of calcium carbonate fillers, surface encapsulation of naturally occurring polymers or their derivatives, preflocculation, precoagulation, cationic modification, filler/size hybrid formation, organic filler engineering, using combinations of different types of available fillers, multilayer deposition modification, modification with polymer latexes or dispersants, physical modification, mechanical modification, surface functionalization, fines-filler composite/hybrids or fiber-filler composite/ hybrid formation, in-situ polymerization modification, surface grafting, physical treatment in the presence of polymeric additives, filler precipitation, and core-shell composite filler engineering.

    Vesela Valkova

    2016-05-01

    Full Text Available This systematic review looks at thematic trends in clinical research publications on dental implants. For this purpose, MEDLINE electronic searches as well as additional hand searches of six main journals in the field were conducted. A total of 2875 clinical studies published between 2001 and 2012 met the inclusion criteria and were subjected to statistical analysis. Hot topics in dental implant literature included immediate loading (14.3%, bone substitutes (11.6%, cross-arch full bridges (8.0%, and immediate implant placement (7.5%. A significant increase in scientific interest for immediate loading (+6.3%, p = 0.001, platform switching (+2.9%, p = 0.001, guided implant surgery (+1.9%, p = 0.011, growth factors (p = 0.014, +1.4%, piezoelectric surgery (+1.3%, p = 0.015, and restorative materials (+0.7%, p = 0.011 was found. A declining scientific interest in onlay grafting (−0.3%, p = 0.042 was recorded. The findings regarding current clinical oral implants research tie in with better-informed consumers and increased patient demands. Our results demonstrate an increasing interest in techniques that avoid complicated procedures such as bone grafting and that reduce treatment duration.

  19. Disentangling Scale Approaches in Governance Research: Comparing Monocentric, Multilevel, and Adaptive Governance

    Maartje van. Lieshout

    2010-12-01

    Full Text Available The question of how to govern the multiscale problems in today's network society is an important topic in the fields of public administration, political sciences, and environmental sciences. How scales are defined, studied, and dealt with varies substantially within and across these fields. This paper aims to reduce the existing conceptual confusion regarding scales by disentangling three representative approaches that address both governance and scaling: monocentric governance, multilevel governance, and adaptive governance. It does so by analyzing the differences in (1 underlying views on governing, (2 assumptions about scales, (3 dominant problem definitions regarding scales, and (4 preferred responses for dealing with multiple scales. Finally, this paper identifies research opportunities within and across these approaches.

  20. Design guidelines for adapting scientific research articles: An example from an introductory level, interdisciplinary program on soft matter

    Langbeheim, Elon; Safran, Samuel A.; Yerushalmi, Edit

    2013-01-01

    We present design guidelines for using Adapted Primary Literature (APL) as part of current interdisciplinary topics to introductory physics students. APL is a text genre that allows students to comprehend a scientific article, while maintaining the core features of the communication among scientists, thus representing an authentic scientific discourse. We describe the adaptation of a research paper by Nobel Laureate Paul Flory on phase equilibrium in polymer-solvent mixtures that was presented to high school students in a project-based unit on soft matter. The adaptation followed two design strategies: a) Making explicit the interplay between the theory and experiment. b) Re-structuring the text to map the theory onto the students' prior knowledge. Specifically, we map the theory of polymer-solvent systems onto a model for binary mixtures of small molecules of equal size that was already studied in class.

    In recent years, many epidemiological and toxicological studies have investigated the adverse effects of air particulate matter (PM) on the cardiovascular system. However, it is difficult for the researchers to have a timely and effective overall command of the latest characteristics and popular topics in such a wide field. Different from the previous reviews, in which the research characteristics and trends are empirically concluded by experts, we try to have a comprehensive evaluation of the above topics for the first time by bibliometric analysis, a quantitative tool in information exploration. This study aims to introduce the bibliometric method into the field of PM and cardiovascular system. The articles were selected by searching PubMed/MEDLINE (from 2007 to 2012) using Medical Subject Headings (MeSH) terms "particulate matter" and "cardiovascular system". A total of 935 eligible articles and 1895 MeSH terms were retrieved and processed by the software Thomson Data Analyzer (TDA). The bibliographic information and the MeSH terms of these articles were classified and analyzed to summarize the research characteristics. The top 200 high-frequency MeSH terms (the cumulative frequency percentage was 74.2%) were clustered for popular-topic conclusion. We summarized the characteristics of published articles, of researcher collaborations and of the contents. Ten clusters of MeSH terms are presented. Six popular topics are concluded and elaborated for reference. Our study presents an overview of the characteristics and popular topics in the field of PM and cardiovascular system in the past five years by bibliometric tools, which may provide a new perspective for future researchers.

    The report proposes five key research themes under the heading 'Future climate and climate adaptation' which can support the Danish climate adaptation efforts. These themes underpin climate adaptation in the light of research needs identified by the research environments and sectors under the government's strategy on adaptation to climate change in Denmark from March 2008. The paper has been prepared within the framework of RESEARCH2015-proposal by the Ministry of Science, Technology and Innovation in order to bring about the knowledge and tools that are demanded by sectors and authorities to implement the government's climate adaptation strategy. This concept paper for research themes is a thorough, holistic and inter-sectoral suggestion for future research priorities in climate adaptation with anchoring in both the research community as well as in the political-administrative system. The five key themes are; 1. Models and climate adaptation; 2. Communities and climate adaptation; 3. Construction and climate adaptation; 4. Landscape and climate adaptation; 5. Climate adaptation in the coastal zone. The overall research needs over a 5 year period is estimated at 700 million DKK, of which 85 million DKK yearly can be estimated to be financed primarily through national basic funds and research council funds. Research is assumed to be coupled to external financing, for which the EU's 7th Framework Program and the Nordic excellence and innovation program in the energy, climate and environment will be significant sources.

  8. How is adaptation, resilience, and vulnerability research engaging with gender?

    Bunce, A.; Ford, J.

    2015-12-01

    The gendered dimensions of climate change have received increasing interest in climate change adaptation, resilience, and vulnerability (ARV) research. Yet concerns have been expressed that engagement with ‘gender’ in this work has been tokenistic. In this context, we ask: how is climate change ARV research engaging with gender? To answer this question, we develop an assessment framework capturing key attributes of engagement and use it to evaluate peer reviewed ARV articles with a focus on gender published since 2006 (n = 123). Results indicate an increase in ARV studies with a gender focus over this period, with the level of gender engagement also increasing. There are a relatively equal numbers of studies categorized as engaging gender at a high, medium, and low level, with studies from Sub-Saharan Africa consistently exhibiting high levels of gender engagement. Gender focused ARV has a strong focus on examining female experiences, with few studies explicitly focusing on men, and no work accounting for those identifying outside the gender binary.

  9. State of research and perspective on adaptive response to low doses of ionizing radiation in Japan

    In a review article entitled ''Physical Benefits from Low Levels of Ionizing Radiation,'' published in Health Physics in December of 1982, Professor T.D. Luckey of the University of Missouri, asserted the ''radiation hormesis'' with 200 references. This resulted in the first International Symposium on Radiation Hormesis in Oakland, California (August 1985). CRIEPI consulted many specialists about Luckey's paper and studied many other papers such as Lorenz, 1954; Luckey, 1980, Liu et al., 1985. Radiation hormesis research in Japan has been based on the rationale that if Luckey's claim were to be true, radiation management in Japan has been extremely erroneous. CRIEPI organized a Hormesis Research Steering Committee composed of leading specialists in the field concerned, and began research in cooperation with a number of universities, as well as the National Cancer Research Institute, and the National Institute of Radiological Sciences. After obtaining interesting results in various experiments on the health effects of exposure to low doses of radiation, we have proceeded on an expanded program, which involves fourteen universities and two research institutes throughout Japan. The interesting results we obtained can be categorized in five groups. 1. Enhancement of immune systems such as lymphocytes and suppression of cancer, 2. Radio-adaptive response relating to the activation of DNA repair and adoptosis, 3. Rejuvenation of cells such as increase of SOD and cell membrane permeability, 4. Radiation effect on neuro-transmitting system through increase of key enzymes, 5. Others, including the therapy of adult-disease such as diabetes and hypertension. We are now carrying out experimental activities on the effects of low-dose radiation on mammals. After several years of research activities, we are recognizing Luckey's claim. Some basic surveys including Hiroshima Nagasaki and animal experiments in Japan have brought us valuable informations on the health effects of low

  18. A Network Analysis of the Teachers and Graduate Students’ Research Topics in the Field of Mass Communication

    Ming-Shu Yuan

    2013-06-01

    Full Text Available The completion of a master’s thesis requires the advisor’s guidance on topic selection, data collection, analysis, interpretation and writing. The advisory committee’s input also contributes to the work. This study conducted content analysis and network analysis on a sample of 547 master’s theses from eight departments of the College of Journalism and Communications of Shih Hsin University to examine the relationships between the advisors and committee members as well as the connections of research topics. The results showed that the topic “lifestyle” have attracted cross-department research interests in the college. The academic network of the college is rather loose, and serving university administration duties may have broadened a faculty member’s centrality in the network. The Department of Communications Management and the Graduate Institute of Communications served as the bridges for the inter-departmental communication in the network. One can understand the interrelations among professors and departments through study on network analysis of thesis as to identify the characteristics of each department, as well as to reveal invisible relations of academic network and scholarly communication.

  19. For a better understanding of adaptive capacity to climate change: a research framework

    It is generally accepted that there exists a systematic link between a low level of adaptive capacity and a low level of development, which thus implies that the poor inevitably have low adaptive capacities. We argue here that this viewpoint is biased because adaptation to climate change is not solely determined by economic and technological capacities. Many other characteristics of a community can play a major role in its ability to react to and anticipate climate changes (e.g. the territorial identity or the social relationships). From our point of view, this limited view of adaptive capacity is related to a relative immaturity of the science of adaptation, a discipline that analyses the processes and determinants of adaptive capacity. This can be explained by the fact that there are currently few existing frameworks for studying adaptive capacity. This paper consists in a proposal for a research framework which is based upon four main fields of investigation: (i) the influential factors of adaptive capacity and their interactions, (ii) the relevant spatial and temporal scales of adaptive capacity, (iii) the links between adaptive capacity, vulnerability and the level of development and (iv) the theoretical links between adaptation and sustainability. These four fields of research should bring new knowledge on adaptive capacity and feed a more general reflection on the adaptation pathways for dealing with climate change. (author)

    The rapidly changing requirements and business rules stimulate software developers to make their applications more dynamic, configurable, and adaptable. An effective way to meet such requirements is to apply an adaptive object-model (AOM). The AOM architecture style is composed of metamodel, model engine and tools. Firstly, two small patterns for building up metamodel are analyzed in detail. Then model engine for interpreting metamodel and tools for end-uses to define and configure object models are discussed. Finally, a novel platform-applicationware-is proposed.

  9. Flash Flood Risk Perception in an Italian Alpine Region. From Research into Adaptive Strategies.

    Scolobig, A.; de Marchi, B.; Borga, M.

    2009-04-01

    Flash floods are characterised by short lead times and high levels of uncertainty. Adaptive strategies to face them need to take into account not only the physical characteristics of the hydro-geological phenomena, but also peoples' risk perceptions, attitudes and behaviours in case of an emergency. It is quite obvious that a precondition for an effective adaptation, e.g. in the case of a warning, is the awareness of being endangered. At the same time the perceptions of those at risk and their likely actions inform hazard warning strategies and recovery programmes following such events. Usually low risk awareness or "wrong perceptions" of the residents are considered among the causes of an inadequate preparedness or response to flash floods as well as a symptom of a scarce self-protection culture. In this paper we will focus on flood risk perception and on how research on this topic may contribute to design adaptive strategies and give inputs to flood policy decisions. We will report on a flood risk perception study of the population residing in four villages in an Italian Alpine Region (Trentino Alto-Adige), carried out between October 2005 and January 2006. A total of 400 standardised questionnaires were submitted to local residents by face to face interviews. The surveys were preceded by focus groups with officers from agencies in charge of flood risk management and semi-structured and in-depth interviews with policy, scientific and technical experts. Survey results indicated that people are not so worried about hydro-geological phenomena, and think that their community is more endangered than themselves. The knowledge of the territory and danger sources, the unpredictability of flash floods and the feeling of safety induced by structural devices are the main elements which make the difference in shaping residents' perceptions. The study also demonstrated a widespread lack of adoption of preparatory measures among residents, together with a general low

  10. Trends and topics in eye disease research in PubMed from 2010 to 2014

    Denion, Eric; Mortemousque, Bruno; Mouriaux, Fréderic

    2016-01-01

    Background: The purpose of this study is to provide a report on scientific production during the period 2010–2014 in order to identify the major topics as well as the predominant actors (journals, countries, continents) involved in the field of eye disease. Methods: A PubMed search was carried out to extract articles related to eye diseases during the period 2010–2014. Data were downloaded and processed through developed PHP scripts for further analysis. Results: A total of 62,123 articles were retrieved. A total of 3,368 different journals were found, and 19 journals were identified as “core journals” according to Braford’s law. English was by far the predominant language. A total of 853,182 MeSH terms were found, representing an average of 13.73 (SD = 4.98) MeSH terms per article. Among these 853,182 MeSH terms, 14,689 different MeSH terms were identified. Vision Disorders, Glaucoma, Diabetic Retinopathy, Macular Degeneration, and Cataract were the most frequent five MeSH terms related to eye diseases. The analysis of the total number of publications showed that Europe and Asia were the most productive continents, and the USA and China the most productive countries. Interestingly, using the mean Five-Year Impact Factor, the two most productive continents were North America and Oceania. After adjustment for population, the overall ranking positions changed in favor of smaller countries (i.e. Iceland, Switzerland, Denmark, and New Zealand), while after adjustment for Gross Domestic Product (GDP), the overall ranking positions changed in favor of some developing countries (Malawi, Guatemala, Singapore). Conclusions: Due to the large number of articles included and the numerous parameters analyzed, this study provides a wide view of scientific productivity related to eye diseases during the period 2010–2014 and allows us to better understand this field.

    2009-12-01

    Full Text Available There have been advances in the understanding of supply chain management (SCM since its inception in the early-1980s. However, there are still some basic issues of SCM that remain unresolved. Much of the research that has been conducted takes one or more of the following three perspectives: (1 development of methods and techniques to study SCM and its components/processes; (2 developing solutions or answers to specific supply chain-related problems or challenges; and/or (3 measuring the results or outcomes of supply chain strategies and tactics. Each of these three perspectives is briefly examined, with selected examples from the literature cited to illustrate the type of research that has been conducted. Some potential areas of research exploration are presented. The areas examined include: theory development, and SCM processes and functions.

  12. Utilization of radiation facilities at TNRC for shielding researches and related topics

    This paper presents the running shielding research activities at Tajura Nuclear research center. The main area of researches are concentrated on the investigation of different types of concrete made from local materials such as conventional concrete, Magnetite-Limonite concrete, and heat resistant concrete. The measuring techniques used were neutron-gamma spectrometry, and activation foils. The measurements were performed using collimated beam of reactor neutrons emitted from one of the horizontal channels, as well as from californium-252 neutron source. The transmitted neutron spectra through concrete barriers of different thicknesses were measured by a scintillation spectrometer with NE-213 liquid organic scintillator. A non-destructive testing of some reactor materials were also carried out using neutron and gamma ray computerized tomography technique (CT). Some experiments were also carried out related to measurements of neutron depth dose distributions inside tissue equivalent materials. 10 figs

  14. Fuels and Space Propellants for Reusable Launch Vehicles: A Small Business Innovation Research Topic and Its Commercial Vision

    Palaszewski, Bryan A.

    1997-01-01

    Under its Small Business Innovation Research (SBIR) program (and with NASA Headquarters support), the NASA Lewis Research Center has initiated a topic entitled "Fuels and Space Propellants for Reusable Launch Vehicles." The aim of this project would be to assist in demonstrating and then commercializing new rocket propellants that are safer and more environmentally sound and that make space operations easier. Soon it will be possible to commercialize many new propellants and their related component technologies because of the large investments being made throughout the Government in rocket propellants and the technologies for using them. This article discusses the commercial vision for these fuels and propellants, the potential for these propellants to reduce space access costs, the options for commercial development, and the benefits to nonaerospace industries. This SBIR topic is designed to foster the development of propellants that provide improved safety, less environmental impact, higher density, higher I(sub sp), and simpler vehicle operations. In the development of aeronautics and space technology, there have been limits to vehicle performance imposed by traditionally used propellants and fuels. Increases in performance are possible with either increased propellant specific impulse, increased density, or both. Flight system safety will also be increased by the use of denser, more viscous propellants and fuels.

  18. Research of Adaptation of Infrastructures for WSRF in Grid Computing

    YANG Qing; WANG Ru-chuan; WANG Hai-yan

    2005-01-01

    One of the challenges that come from the development of Grid Computing applications is to predigest complicated process of compiling, deploying on the infrastructures and toolkits such as Globus Toolkit. As we explain in this article, we think it is essential to find the solution for rapid Grid Computing applications development. Gbuilder is just such a tool we worked out for rapid develop on extant Grid Computing infrastructure platforms. By using Gbuilder, applications should be able to react dynamically to different infrastructures and toolkits. Since WS-Resource Framework (WSRF) specifications provide technique standard to developers to declare and implement the association between Web service and one or more stateful resources, we aim at making infrastructures provide WS-Resource according these specifications automatically by adding a middleware. This paper focuses on the adapting mechanisms that are provided as the lowermost component of Gbuilder. First we study the adapting model for Globus Toolkit in patterns of combination dynamic and static. Then it describes how to apply the dynam-static adaptation flexibly to adjust different infrastructures to provide WS-Resource based on WSRF. At last, it comes along the conclusion and we give out our future works.

  19. Evaluation of the Benefits Attributable to Automotive Lightweight Materials Program Research and Development Projects; TOPICAL

    The purpose of this project is to identify and test methods appropriate for estimating the benefits attributable to research and development (R and D) projects funded by the Automotive Lightweight Materials (ALM) Program of the Office of Advanced Automotive Technologies (OAAT) of the U.S. Department of Energy (DOE). Funded projects range from basic materials science research to applied research in production environments. Collaborators on these projects include national laboratories, universities, and private sector firms, such as leading automobile manufacturers and their suppliers. Three ALM R and D projects were chosen for this pilot evaluation: Low-Cost, Continuous Cast Aluminum Sheet; Advanced Forming Technologies for Aluminum; and Manufacturing of Composite Automotive Structures. These projects were chosen because they represent a range of benefits evaluation situations. The first project resulted in an improved process that may be commercialized. The second project is on going and has two distinct components. The third project has yielded an improved technology that has been commercialized. This completed project also benefited from numerous complementary projects

  2. Adapt

    Bargatze, L. F.

    2015-12-01

    Active Data Archive Product Tracking (ADAPT) is a collection of software routines that permits one to generate XML metadata files to describe and register data products in support of the NASA Heliophysics Virtual Observatory VxO effort. ADAPT is also a philosophy. The ADAPT concept is to use any and all available metadata associated with scientific data to produce XML metadata descriptions in a consistent, uniform, and organized fashion to provide blanket access to the full complement of data stored on a targeted data server. In this poster, we present an application of ADAPT to describe all of the data products that are stored by using the Common Data File (CDF) format served out by the CDAWEB and SPDF data servers hosted at the NASA Goddard Space Flight Center. These data servers are the primary repositories for NASA Heliophysics data. For this purpose, the ADAPT routines have been used to generate data resource descriptions by using an XML schema named Space Physics Archive, Search, and Extract (SPASE). SPASE is the designated standard for documenting Heliophysics data products, as adopted by the Heliophysics Data and Model Consortium. The set of SPASE XML resource descriptions produced by ADAPT includes high-level descriptions of numerical data products, display data products, or catalogs and also includes low-level "Granule" descriptions. A SPASE Granule is effectively a universal access metadata resource; a Granule associates an individual data file (e.g. a CDF file) with a "parent" high-level data resource description, assigns a resource identifier to the file, and lists the corresponding assess URL(s). The CDAWEB and SPDF file systems were queried to provide the input required by the ADAPT software to create an initial set of SPASE metadata resource descriptions. Then, the CDAWEB and SPDF data repositories were queried subsequently on a nightly basis and the CDF file lists were checked for any changes such as the occurrence of new, modified, or deleted

  3. Climate change and health in the United States of America: impacts, adaptations, and research

    After a description of the various impacts of climate change on human health, this report describes and comments the impacts of climate change on health in the USA: impacts of heat waves, of air quality degradation, of extreme climate events, of climate change on infectious diseases and allergies, regional impacts of climate change.

  4. Compilation status and research topics in Hokkaido University nuclear reaction data centre

    The Hokkaido University Nuclear Reaction Data Centre (JCPRG) is a member of the International Network of Nuclear Reaction Data Centres (NRDC) under the auspices of the International Atomic Energy Agency (IAEA). JCPRG contributes about 10 percent of the data on charged-particle nuclear reactions in the EXFOR. In addition to the worldwide collaboration of compilation, Asian collaboration on compilation and evaluation was also promoted. As a result of this promotion, a research on the 9Be+n reaction was launched between Hokkaido University and Al-Farabi Kazakh National University. Beryllium is one of essential materials as a target window and a reflector for a spallation neutron source. The theoretical study and evaluation of the 9Be+n reaction are indispensable for nuclear engineering. We report current status of our activity and collaboration on compilation and evaluation of nuclear reaction data. (author)

  5. [Psychoanalysis and early childhood research. Some basic topics of the debate].

    Dornes, M

    1993-12-01

    In Dornes' view it is time for psychoanalytic development psychology to stand back from its preoccupation with the reconstructed child and gain access to the real child via direct observation, thus re-establishing contact with the state of research in neighbouring disciplines. Such direct observation would both stimulate a review of the cogency of the symbiosis and borderline theories of normal early development and question the assumption of lack of psychic differentiation in newborn children. So far, the author contends, psychoanalytic theory has both underestimated and overestimated the abilities of infants, ascribing to them in the latter case the capacity for complicated psychic operations (hallucinatory wish fulfillment, grandeur fantasies, projective identifications) which are in fact beyond their powers.

  6. Virtual reality in planning and operations from research topic to practical issue

    During the last decade of research and development on advanced visualization systems for the nuclear industry, the available technology has evolved significantly. In the same period, nuclear companies have entered a more competitive environment due to the increasingly open electricity market, resulting in strong demands on cost effective operations. This paper reports on some of the 3D applications developed by Inst. for Energy Technology in this time period, and on the emerging possibilities for practical applications of Virtual and Augmented Reality. Finally the paper proposes that well-considered deployment of recent and on-going technological advances in this field can be a contribution to improving economy and efficiency without compromising safety.

    Ute Armbruster; Paolo Pesaresi; Mathias Pribil; Alexander Hertle; Dario Leister

    2011-01-01

    Chloroplasts, the green differentiation form of plastids, are the sites of photosynthesis and other important plant functions. Genetic and genomic technologies have greatly boosted the rate of discovery and functional characterization of chloroplast proteins during the past decade. Indeed, data obtained using high-throughput methodologies, in particular proteomics and transcriptomics, are now routinely used to assign functions to chloroplast proteins. Our knowledge of many chloroplast processes, notably photosynthesis and photorespiration, has reached such an advanced state that biotechnological approaches to crop improvement now seem feasible. Meanwhile, efforts to identify the entire complement of chloroplast proteins and their interactions are progressing rapidly, making the organelle a prime target for systems biology research in plants.

  8. Key Topics for High-Lift Research: A Joint Wind Tunnel/Flight Test Approach

    Fisher, David; Thomas, Flint O.; Nelson, Robert C.

    1996-01-01

    Future high-lift systems must achieve improved aerodynamic performance with simpler designs that involve fewer elements and reduced maintenance costs. To expeditiously achieve this, reliable CFD design tools are required. The development of useful CFD-based design tools for high lift systems requires increased attention to unresolved flow physics issues. The complex flow field over any multi-element airfoil may be broken down into certain generic component flows which are termed high-lift building block flows. In this report a broad spectrum of key flow field physics issues relevant to the design of improved high lift systems are considered. It is demonstrated that in-flight experiments utilizing the NASA Dryden Flight Test Fixture (which is essentially an instrumented ventral fin) carried on an F-15B support aircraft can provide a novel and cost effective method by which both Reynolds and Mach number effects associated with specific high lift building block flows can be investigated. These in-flight high lift building block flow experiments are most effective when performed in conjunction with coordinated ground based wind tunnel experiments in low speed facilities. For illustrative purposes three specific examples of in-flight high lift building block flow experiments capable of yielding a high payoff are described. The report concludes with a description of a joint wind tunnel/flight test approach to high lift aerodynamics research.

  14. Adapting Project Management Practices to Research-Based Projects

    Bahr, P.; Baker, T.; Corbin, B.; Keith, L.; Loerch, L.; Mullenax, C.; Myers, R.; Rhodes, B.; Skytland, N.

    2007-01-01

    From dealing with the inherent uncertainties in outcomes of scientific research to the lack of applicability of current NASA Procedural Requirements guidance documentation, research-based projects present challenges that require unique application of classical project management techniques. If additionally challenged by the creation of a new program transitioning from basic to applied research in a technical environment often unfamiliar with the cost and schedule constraints addressed by project management practices, such projects can find themselves struggling throughout their life cycles. Finally, supplying deliverables to a prime vehicle customer, also in the formative stage, adds further complexity to the development and management of research-based projects. The Biomedical Research and Countermeasures Projects Branch at NASA Johnson Space Center encompasses several diverse applied research-based or research-enabling projects within the newly-formed Human Research Program. This presentation will provide a brief overview of the organizational structure and environment in which these projects operate and how the projects coordinate to address and manage technical requirements. We will identify several of the challenges (cost, technical, schedule, and personnel) encountered by projects across the Branch, present case reports of actions taken and techniques implemented to deal with these challenges, and then close the session with an open forum discussion of remaining challenges and potential mitigations.

  16. RESEARCH ON ADAPTIVE DATA COMPRESSION METHOD FOR TRIANGULATED SURFACES

    Wang Wen; Wu Shixiong; Chen Zichen

    2004-01-01

    NC code or STL file can be generated directly from measuring data in a fast reverse-engineering mode.Compressing the massive data from laser scanner is the key of the new mode.An adaptive compression method based on triangulated-surfaces model is put forward.Normal-vector angles between triangles are computed to find prime vertices for removal.Ring data structure is adopted to save massive data effectively.It allows the efficient retrieval of all neighboring vertices and triangles of a given vertices.To avoid long and thin triangles,a new re-triangulation approach based on normalized minimum-vertex-distance is proposed,in which the vertex distance and interior angle of triangle are considered.Results indicate that the compression method has high efficiency and can get reliable precision.The method can be applied in fast reverse engineering to acquire an optimal subset of the original massive data.

  17. Hydrogen from biomass: state of the art and research challenges; TOPICAL

    appropriate feedstocks and deployment scenarios that match hydrogen to the local markets. Co-production opportunities are of particular interest for near-term deployment since multiple products improve the economics; however, co-product development is not covered in this report. Biomass has the potential to accelerate the realization of hydrogen as a major fuel of the future. Since biomass is renewable and consumes atmospheric CO2 during growth, it can have a small net CO2 impact compared to fossil fuels. However, hydrogen from biomass has major challenges. There are no completed technology demonstrations. The yield of hydrogen is low from biomass since the hydrogen content in biomass is low to being with (approximately 6% versus 25% for methane) and the energy content is low due to the 40% oxygen content of biomass. Since over half of the hydrogen from biomass comes from splitting water in the steam reforming reaction, the energy content of the feedstock is an inherent limitation of the process . The low yield of hydrogen on a weight basis is misleading since the energy conversion efficiency is high. However, the cost for growing, harvesting, and transporting biomass is high. Thus even with reasonable energy efficiencies, it is not presently economically competitive with natural gas steam reforming for stand-alone hydrogen without the advantage of high-value co-products. Additionally, as with all sources of hydrogen, production from biomass will require appropriate hydrogen storage and utilization systems to be developed and deployed. The report also looked at promising areas for further research and development. The major areas for R,D and D are: feedstock preparation and feeding; gasification gas conditioning; system integration; modular systems development; valuable co-product integration; and larger-scale demonstrations. These are in addition to the challenges for any hydrogen process in storage and utilization technologies

  18. Pressurized fluidized-bed hydroretorting of Eastern oil shales -- Beneficiation. Topical report for Task 4, Beneficiation research

    Roberts, M.J.; Lau, F.S.; Mensinger, M.C. [Institute of Gas Technology, Chicago, IL (United States); Schultz, C.W.; Mehta, R.K.; Lamont, W.E. [Alabama Univ., University, AL (United States); Chiang, S.H.; Venkatadri, R. [Pittsburgh Univ., PA (United States); Misra, M. [Nevada Univ., Reno, NV (United States)

    1992-05-01

    The Mineral Resources Institute at the University of Alabama, along with investigators from the University of Pittsburgh and the University of Nevada-Reno, have conducted a research program on the beneficiation, of Eastern oil shales. The objective of the research program was to evaluate and adapt those new and emerging technologies that have the potential to improve the economics of recovering oil from Eastern oil shales. The technologies evaluated in this program can be grouped into three areas: fine grinding kerogen/mineral matter separation, and waste treatment and disposal. Four subtasks were defined in the area of fine grinding. They were as follows: Ultrasonic Grinding, Pressure Cycle Comminution, Stirred Ball Mill Grinding, and Grinding Circuit Optimization. The planned Ultrasonic grinding research was terminated when the company that had contracted to do the research failed. Three technologies for effecting a separation of kerogen from its associated mineral matter were evaluated: column flotation, the air-sparged hydrocyclone, and the LICADO process. Column flotation proved to be the most effective means of making the kerogen/mineral matter separation. No problems are expected in the disposal of oil shale tailings. It is assumed that the tailings will be placed in a sealed pond and the water recycled to the plant as is the normal practice. It may be advantageous, however, to conduct further research on the recovery of metals as by-products and to assess the market for tailings as an ingredient in cement making.

  19. The application of computers to controlled thermonuclear research. A report to the USAEC Division of Controlled Thermonuclear Research; TOPICAL

    This report surveys the need for large computers in analyzing the properties of magnetically confined plasmas and simulating the characteristics of fusion reactors. The major conclusion of the report is that, to meet the program schedule developed by Magnetic Confinement Systems, it would be necessary to immediately scale up the CTR (controlled thermonuclear research) computerized effort to a level of two Class IV computers by FY 1975. Based on this report, and in an attempt to best meet this need, it was decided to establish the National CTR Computer Center at the Lawrence Livermore Laboratory

  20. Increasing sustainable stormwater management adaption through transdisciplinary research

    Wingfield, Thea; Potter, Karen; Jones, Gareth; Spees, Jack; Macdonald, Neil

    2016-04-01

    The Ribble Rivers Trust leads a partnership of land and water management organisations that use a holistic approach to water management in the Ribble catchment. They are interested in incorporating sustainable stormwater systems, into their program of delivery with a view to ensuring that their activities to improve the environments and habitats of the catchment also contribute to reducing flood risk. A methodology, to locate interventions that would slow water within the catchment are identified; however partner buy in, institutional caution and economic barriers are felt to be hindering delivery. In response a transdisciplinary research project in which both the academics of the University of Liverpool and the practitioners of The Ribble Rivers Trust are active investigators has been established. The project aims to increase the uptake of sustainable stormwater management techniques through the analysis of the institutional, experiential and governance processes and their interactions with the physical hydrological processes governing stormwater systems. Research that is transdisciplinary must integrate academic knowledge with practitioner, local understanding and practice. Furthermore methodologies belonging to different academic fields must be blended together to collect, analyse and interpret data in order to examine complex problems through different disciplinary lenses in an integrated way. This approach has been developed in response to the complex relationships of cause and effect of contemporary inter-related economic, environmental and societal challenges. There have been a number of challenges to overcome as transdisciplinary researchers, the first and most important was to understand the different research philosophies and theoretical assumptions behind various natural science and social science research methods. Without this understanding research methodologies could be flawed and would not be effectively integrated and the data would not be

  1. The dimension of adaptive behavior in mental retardation research: an analysis of recent practices.

    Smith, J D; Polloway, E A

    1979-09-01

    The dimension of adaptive behavior has been accepted by many professionals as an important component of identification in mental retardation since the definitions of Heber (1961) and Grossman (1973). In order to investigate the impact of this more comprehensive concept of mental retardation on research practices, we analyzed the use of adaptive behavior in the selection and description of subjects. This investigation was based in research articles published in the Americal Journal of Mental Deficiency from 1974 through 1978. In a significant percentage of the articles reviewed, the researchers had not attended to adaptive behavior and used only measures of intellectual functioning for descriptive purposes. These results were discussed in light of the validity of research on mental retardation. Recommendations were included for future research practices. PMID:495669

  2. Pathobiology of biliary epithelia and cholangiocarcinoma: proceedings of the Henry M. and Lillian Stratton Basic Research Single-Topic Conference.

    Sirica, Alphonse E; Nathanson, Michael H; Gores, Gregory J; Larusso, Nicholas F

    2008-12-01

    In June 2008, the American Association for the Study of Liver Diseases (AASLD) sponsored the Henry M. and Lillian Stratton Basic Research Single-Topic Conference on the Pathobiology of Biliary Epithelia and Cholangiocarcinoma, which was held in Atlanta, GA. Attendees from 12 different countries participated in this conference, making it a truly international scientific event. Both oral and poster presentations were given by multidisciplinary experts, who highlighted important areas of current basic and translational research on biliary epithelial cell biology and pathophysiology, and on the etiology, cellular and molecular pathogenesis, and target-based therapy of cholangiocarcinoma. The specific goals and objectives of the conference were: (1) to advance knowledge of basic and molecular mechanisms underlying developmental and proliferative disorders of the biliary tract; (2) to foster a better and more comprehensive understanding of mechanisms regulating biliary epithelial (cholangiocyte) growth and transport, signaling, cell survival, and abnormalities that result in disease; and (3) to understand basic mechanisms of cholangiocarcinoma development and progression, with the added goal of identifying and exploiting potentially critical molecular pathways that may be targeted therapeutically. A number of interrelated themes emerged from the oral and poster sessions that affected current understandings of the complex organization of transcriptional and signaling mechanisms that regulate bile duct development, hepatic progenitor cell expansion, cholangiocyte secretory functions and proliferation, and mechanisms of cholangiocarcinogenesis and malignant cholangiocyte progression. Most notable were the critical questions raised as to how best to exploit aberrant signaling pathways associated with biliary disease as potential targets for therapy. PMID:18855901

  4. Topic Tracking with Dynamic Topic Model and Topic-based Weighting Method

    Xiaoyan Zhang

    2010-05-01

    Full Text Available In topic tracking, a topic is usually described by several stories. How to represent a topic is always an issue and a difficult problem in the research on topic tracking. To emphasis the topic in stories, we provide an improved topic-based tf*idf weighting method to measure the topical importance of the features in the representation model. To overcome the topic drift problem and filter the noise existed in the tracked topic description, a dynamic topic model is proposed based on the static model. It extends the initial topic model with the information from the incoming related stories and filters the noise using the latest unrelated story. The topic tracking systems are implemented on the TDT4 Chinese corpus. The experimental results indicate that both the new weighting method and the dynamic model can improve the tracking performance.

  6. Intrinsic motivation inventory: an adapted measure for schizophrenia research.

    Choi, Jimmy; Mogami, Tamiko; Medalia, Alice

    2010-09-01

    This article describes the psychometric validation of a scale designed to measure intrinsic motivation (IM) in schizophrenia. Recent studies have highlighted the relationship between motivation and functional outcome in schizophrenia and identified IM as an important mediating factor between neurocognition and psychosocial outcome. It therefore becomes imperative to have validated measures of IM for empirical use. To that end, we validated a self-report IM scale that gauges the central motivational structures identified by Self-determinism Theory as pertinent to cognitive task engagement, skill acquisition, treatment compliance, and remediation outcome. Participants were schizophrenia outpatients involved in a cognitive remediation study (n = 58), a convenience subsample of clinically stable schizophrenia outpatients (n = 15), and a group of healthy normals (n = 22). The Intrinsic Motivation Inventory for Schizophrenia Research (IMI-SR) is a concise instrument, possessing good internal consistency (alpha = .92) and test-retest reliability (intraclass correlation = .77). Data were analyzed to abridge the original 54 items into a final 21-item questionnaire comprised of 3 domains relevant to motivation for treatments (interest/enjoyment, perceived choice, value/usefulness). The scale was highly associated with germane constructs of motivation for health-related behaviors, including perceived competency for attempting challenging tasks and autonomous treatment engagement. Importantly, the scale was able to distinguish improvers and nonimprovers on a cognitive task and actual learning exercises, delineate high vs low treatment attendance, and demonstrate sensitivity to motivational changes due to intervention variation. The IMI-SR is a viable instrument to measure IM in schizophrenia as part of a cognitive remediation protocol or psychosocial rehabilitation program. PMID:19386577

    Tabak, Rachel G; Sinclair, Kàimi A; Baumann, Ana A; Racette, Susan B; Sebert Kuhlmann, Anne; Johnson-Jennings, Michelle D; Brownson, Ross C

    2015-12-01

    The Diabetes Prevention Program (DPP) has been shown to prevent type 2 diabetes through lifestyle modification. The purpose of this study was to describe the literature on DPP translation, synthesizing studies using cultural adaptation and implementation research. A systematic search was conducted. Original studies evaluating DPP implementation and/or cultural adaptation were included. Data about cultural adaptation, implementation outcomes, and translation strategies was abstracted. A total of 44 were included, of which 15 reported cultural adaptations and 38 explored implementation. Many studies shortened the program length and reported a group format. The most commonly reported cultural adaptation (13 of 15) was with content. At the individual level, the most frequently assessed implementation outcome (n = 30) was adoption. Feasibility was most common (n = 32) at the organization level. The DPP is being tested in a variety of settings and populations, using numerous translational strategies and cultural adaptations. Implementation research that identifies, evaluates, and reports efforts to translate the DPP into practice is crucial. PMID:26622913

  11. Towards an integrated agenda for adaptation research: theory, practice, and policy: Strategy paper

    Wilbanks, Thomas J [ORNL; Patwardhan, Anand [Indian Institute of Technology, Bombay; Downing, Tom [Stockholm Environment Institute, UK; Leary, Neil [Dickinson College

    2009-01-01

    Adaptation to the adverse impacts of climate change has been recognized as a priority area for national and international policy. The findings of the Fourth Assessment Report of the IPCC have reemphasized the urgency of action and the scale of response needed to cope with climate change outcomes. The scientific community has an important role to play in advancing the information and knowledge base that would help in identifying, developing and implementing effective responses to enhance adaptive capacity and reduce vulnerability. This paper examines the way in which science and research could advance the adaptation agenda. To do so, we pose a number of questions aimed at identifying the knowledge gaps and research needs. We argue that in order to address these science and research needs, an integrated approach is necessary, one that combines new knowledge with new approaches for knowledge generation, and where research and practice co-evolve; and that such a learning-by-doing approach is essential to rapidly scale up and implement concrete adaptation actions.

  13. Status of Issues in U.S. Edge-Plasma Research and Priority Topics for the Next Five Years

    The Edge Coordinating Committee (ECC) was formed in July 14-15, 2004 when OFES Theory Team invited 14 plasma researchers to a two-day meeting in Germantown, MD to discuss the state of edge-plasma research in the U.S. with a focus on theory and modeling (see http://www.mfescience.org/ecc/ ecc/). At that time, OFES tasked the ECC with providing, in about a six month period, a report on the present status of key issues in this area together with a roadmap of what range of activities should be undertaken in the next five years to resolve these issues. This document is a response to that charge. Future edge-plasma research described here is assumed to fit into a budget constraint of a ''flat budget,'' with some additional activities cited for budget increases of as much as 50%. To obtain some measure of the relative fraction of OFES Theory funding presently devoted to edge plasma research, the OFES Theory Team informally surveyed funded work they support in this area at National Labs, Universities, and industry. John Mandrekas reported to us that approximately 10% of the present budget goes to edge-physics areas at 10 institutions, for a total of ∼$2.5M each year. While not explicitly estimated, we note that there are also important edge plasma projects in the Plasma Technology program, especially related to plasma/material sputtering interactions, near-surface plasma chemistry and transport, and impurity transport. Likewise, the Confinement Program has important efforts in interpreting edge-plasma data through modeling codes. This initial status/roadmap work of the ECC is complimentary to the Fusion Energy Science Sciences Advisory Committee (FESAC) Panel on Program Priorities (see http://www.mfescience.org/fesac/ fesac/). This Panel is charged with identifying major science and technology issues for all of controlled fusion and also with recommending campaigns to address these issues. The Panel has organized their report along six thematic areas, one of which

  16. Spotlight Topics

    A Spotlight Topic consists of a set of two or more review articles focused on a specific subject in surface science. The topics are recommended by the Board of Editors. A topic may be chosen because it is particularly new or fast-breaking, thus deserving introduction to the general readership. Or, it may be because a topic is especially controversial or confusing, requiring clarification by experts. Each review will give a critical assessment rather than an encyclopedic report. While our editors always will insist on fairness and accuracy, any review which forwards an opinion is bound to be somewhat subjective. Therefore, it is the editors' wish that the set of reviews written by different authors on the same subject matter will provide a broad and balanced viewpoint. It is often the case that an author who is an expert in a technique or method may be especially enthusiastic or critical about this technique or method. A companion review in the set may provide a different viewpoint. We are hopeful that the reader, after studying these reviews and checking some of the key references, will obtain an informed opinion of the subject. We think the set of reviews in a spotlight area will considerably shorten the ``learning time'' that a nonexpert would otherwise need to become knowledgeable about a subject. In this issue, we feature a spotlight topic on oxide surfaces. The set contains an overview article by Jacques Jupille, and four articles written by G. Pacchioni, F. Cosandey and T. E. Madey, B. G. Daniels, R. Lindsay and G. Thornton, and C. Noguera respectively. Of these, the article by Pacchioni has already appeared in SRL 7, 277 (2000). The other three articles appear in this issue. A reader who wishes to suggest a spotlight topic or recommend authors to write such reviews should contact the Editor-in-Chief. We would like to hear from you.

  17. Planning adaptation for food and farming: lessons from 40 year's research

    Reid, Hannah; Chambwera, Muyeye; Murray, Laurel

    2012-05-15

    Local farmers and pastoralists in poor countries have long coped with droughts, floods and variable rainfall patterns. This first-hand experience is invaluable for those working on climate change adaptation policies, but how do we access it? The International Institute for Environment and Development (IIED) has 40 years' experience working alongside vulnerable communities to help inform regional, national and global policies. Our research has shown that measures to increase climate change resilience must view food, energy, water and waste management systems as interconnected and mutually dependent. This holistic approach must also be applied to economic analysis on adaptation planning. Similarly, it is vital to use traditional knowledge and management skills, which can further support adaptation planning. Taking these lessons into account, we can then address the emerging policy challenges that we face.

  2. Cooperative Research and Development Agreement Final Report for Cooperative Research and Development Agreement Number ORNL93-0237 Adhesive Bonding Technologies for Automotive Structural Composites; TOPICAL

    In 1993, the Oak Ridge National Laboratory (ORNL) entered into a Cooperative Research and Development Agreement (CRADA) with the Automotive Composites Consortium (ACC) to conduct research and development that would overcome technological hurdles to the adhesive bonding of current and future automotive materials. This effort is part of a larger Department of Energy (DOE) program to promote the use of lighter weight materials in automotive structures for the purpose of increasing fuel efficiency and reducing environmental pollutant emissions. In accomplishing this mission, the bonding of similar and dissimilar materials was identified as being of primary importance to the automotive industry since this enabling technology would give designers the freedom to choose from an expanded menu of low mass materials for component weight reduction. The research undertaken under this CRADA addresses the following areas of importance: bulk material characterization, structural fracture mechanics, modeling/characterization, process control and nondestructive evaluation (PC/NDE), manufacturing demonstration, and advanced processing. For the bulk material characterization task, the individual material properties of the adherends and adhesives were characterized. This included generating a database of mechanical and physical properties, after identifying and developing standard test methods to obtain properties. The structural fracture mechanics task concentrated on test development to characterize the fracture toughness of adhesively bonded joints subjected to Mode I, Mode II and mixed-mode conditions. Standard test procedures for quantifying an adhesive/adherend system's resistance to crack growth were developed for use by industry. In the modeling/characterization task, fracture mechanics-based design guidelines and predictive methodologies have been developed which will facilitate iteration on design concepts for bonded joints while alleviating the need for extensive testing

  3. Technical Note: DIRART- A software suite for deformable image registration and adaptive radiotherapy research

    Purpose: Recent years have witnessed tremendous progress in image guide radiotherapy technology and a growing interest in the possibilities for adapting treatment planning and delivery over the course of treatment. One obstacle faced by the research community has been the lack of a comprehensive open-source software toolkit dedicated for adaptive radiotherapy (ART). To address this need, the authors have developed a software suite called the Deformable Image Registration and Adaptive Radiotherapy Toolkit (DIRART). Methods: DIRART is an open-source toolkit developed in MATLAB. It is designed in an object-oriented style with focus on user-friendliness, features, and flexibility. It contains four classes of DIR algorithms, including the newer inverse consistency algorithms to provide consistent displacement vector field in both directions. It also contains common ART functions, an integrated graphical user interface, a variety of visualization and image-processing features, dose metric analysis functions, and interface routines. These interface routines make DIRART a powerful complement to the Computational Environment for Radiotherapy Research (CERR) and popular image-processing toolkits such as ITK. Results: DIRART provides a set of image processing/registration algorithms and postprocessing functions to facilitate the development and testing of DIR algorithms. It also offers a good amount of options for DIR results visualization, evaluation, and validation. Conclusions: By exchanging data with treatment planning systems via DICOM-RT files and CERR, and by bringing image registration algorithms closer to radiotherapy applications, DIRART is potentially a convenient and flexible platform that may facilitate ART and DIR research.

  4. Genomic resources for a model in adaptation and speciation research: characterization of the Poecilia mexicana transcriptome

    Kelley Joanna L

    2012-11-01

    Full Text Available Abstract Background Elucidating the genomic basis of adaptation and speciation is a major challenge in natural systems with large quantities of environmental and phenotypic data, mostly because of the scarcity of genomic resources for non-model organisms. The Atlantic molly (Poecilia mexicana, Poeciliidae is a small livebearing fish that has been extensively studied for evolutionary ecology research, particularly because this species has repeatedly colonized extreme environments in the form of caves and toxic hydrogen sulfide containing springs. In such extreme environments, populations show strong patterns of adaptive trait divergence and the emergence of reproductive isolation. Here, we used RNA-sequencing to assemble and annotate the first transcriptome of P. mexicana to facilitate ecological genomics studies in the future and aid the identification of genes underlying adaptation and speciation in the system. Description We provide the first annotated reference transcriptome of P. mexicana. Our transcriptome shows high congruence with other published fish transcriptomes, including that of the guppy, medaka, zebrafish, and stickleback. Transcriptome annotation uncovered the presence of candidate genes relevant in the study of adaptation to extreme environments. We describe general and oxidative stress response genes as well as genes involved in pathways induced by hypoxia or involved in sulfide metabolism. To facilitate future comparative analyses, we also conducted quantitative comparisons between P. mexicana from different river drainages. 106,524 single nucleotide polymorphisms were detected in our dataset, including potential markers that are putatively fixed across drainages. Furthermore, specimens from different drainages exhibited some consistent differences in gene regulation. Conclusions Our study provides a valuable genomic resource to study the molecular underpinnings of adaptation to extreme environments in replicated sulfide

  5. Research Progress of Space-Time Adaptive Detection for Airborne Radar

    Wang Yong-liang

    2014-04-01

    Full Text Available Compared with Space-Time Adaptive Processing (STAP, Space-Time Adaptive Detection (STAD employs the data in the cell under test and those in the training to form reasonable detection statistics and consequently decides whether the target exists or not. The STAD has concise processing procedure and flexible design. Furthermore, the detection statistics usually possess the Constant False Alarm Rate (CFAR property, and hence it needs no additional CFAR processing. More importantly, the STAD usually exhibits improved detection performance than that of the conventional processing, which first suppresses the clutter then adopts other detection strategy. In this paper, we first summarize the key strongpoint of the STAD, then make a classification for the STAD, and finally give some future research tracks.

    Serengil Y

    2011-04-01

    Full Text Available Climate change and air pollution are two of the anthropogenic stressors that require international collaboration. Influence mechanisms and combating strategies towards them have similarities to some extent. Impacts of air pollution and climate change have long been studied under IUFRO Research Group 7.01 and state of the art findings are presented at biannual meetings. Monitoring, modelling, assessment of multiple stressors, ecophysiology, and nutrient cycles have been thoroughly studied aspects of climate change and air pollution research for a long time under the umbrella of IUFRO RG 7.01. Recently, social and economic issues together with water relations are gaining more attention in parallel with science requirements on adaptation. In this paper, we summarise the main research needs emphasized at the recent 24th IUFRO RG 7.01 Conference titled “Adaptation of Forest Ecosystems to Air Pollution and Climate Change”. One important conclusion of the conference was the need for information on nutritional status of forest stands for sustainable forest management. It has been suggested to maintain long-term monitoring programs and to account for the effects of extreme years, and past and present management practices. Long-term monitoring can also help to understand the effects of forestry treatments on the nutrient and water budgets of the ecosystems which may enable to improve management practices like water saving silviculture.

  8. Adapting Pd Gains with Neural Network for Egyptian Second Research Reactor (ETRR-2)

    There is no doubt that selection of conventional Pd gains has a great influence over the system performance. So, this paper presents a developed adapted Pd (APD) control system to fit suitable control action. This system is based on ANN to select, on-line, the proper gains for Pd controller. Both Pd and developed APD control systems are simulated with Egyptian Second Research Reactor (ETRR-2) model subjected to different perturbations. Simulation results proved that, APD controller has faster response than Pd, besides its capability of absorbing more reactivity variations

  14. Participatory Research for Adaptive Water Management in a Transition Country - a Case Study from Uzbekistan

    Nilufar Matin

    2010-09-01

    Full Text Available Participatory research has in recent years become a popular approach for problem-oriented scientific research that aims to tackle complex problems in a real management context. Within the European Union project NeWater, stakeholder processes were initiated in seven case studies to develop approaches for adaptive water management. The Uzbek part of the Amudarya River basin was one of the studied river basins. However, given the current political and cultural context in Uzbekistan, which provides little room for stakeholder participation, it was unclear to what extent participation could be realized there. In this paper, we present an evaluation of the participatory research carried out in the Amudarya case study with respect to (i the choice and application of different participatory methods and their adaptation to the given political, socioeconomic, and cultural environment, (ii their usefulness in improving system understanding and developing strategies and measures to improve water management and monitoring, and (iii their acceptance and suitability for enhancing policy-making processes in the Amudarya River basin context. The main lessons learned from the comparison of the different participatory methods were (1 the stakeholder process provided an opportunity for meetings and discussions among stakeholders from different organizational levels and thus promoted communication between different levels and organizations, and (2 in a context where most stakeholders are not generally involved in policy-making, there is a danger of raising expectations that a research project cannot meet, e.g., of transferring local interests to higher levels. Our experience shows that in order to choose participatory methods and adapt them to the Uzbek cultural and political setting (and most likely this applies to other post-Soviet transition countries as well, four aspects should be taken into account: the time required to prepare and apply the method, good

  15. Adaptive Water Governance: Assessing the Institutional Prescriptions of Adaptive (Co-Management from a Governance Perspective and Defining a Research Agenda

    Claudia Pahl-Wostl

    2009-06-01

    Full Text Available This article assesses the institutional prescriptions of adaptive (co-management based on a literature review of the (water governance literature. The adaptive (co-management literature contains four institutional prescriptions: collaboration in a polycentric governance system, public participation, an experimental approach to resource management, and management at the bioregional scale. These prescriptions largely resonate with the theoretical and empirical insights embedded in the (water governance literature. However, this literature also predicts various problems. In particular, attention is called to the complexities associated with participation and collaboration, the difficulty of experimenting in a real-world setting, and the politicized nature of discussion on governance at the bioregional scale. We conclude this article by outlining a common research agenda that invites the collaborative efforts of adaptive (co-management and governance scholars.

  16. [Topical contraceptives].

    Alipov, V I; Korkhov, V V

    1982-02-01

    Recently there has been little interest in topical contraceptives. The most popular are the cervical cap and the diaphragm. Other types of mechanical contraceptive devices are being investigated. Standley and Kessler have developed a device for introduction into the cervical canal with a reservoir of spermatocide, it does not block the flow of blood during menstruation. New models of vaginal rings are also being developed which are simple enough for self-insertion and also contain a reservoir of spermatocide. Work is being done on spermatocide-containing sponges in many countries. Another project being investigated is the possibility of using natural proteins, collagens, and other substances which absorb spermatozoids. The ancients used various vaginal suppositories to kill spermatozoids; in the late 19th century quinine sulfate was used for this, and a variety of substances have been used recently. These spermicidal creams also have the advantage of acting as anti-infectious agents in many cases. But they do have some negative effects. They are about 85% effective, are local irritants, and some cause discomfort during intercourse. And it is possible that some are resorbed by the body and act on the liver and other organs. Vaginal globules and suppositories are also popular. The "Kontraceptin-T" brand contains quinosol, boric acid, and tannin. There are also foaming tablets which are mixed with water and then introduced. New locally-active chemical substances are being developed in Japan, West Germany, and the USSR. Kontraceptin-E contains paranonyl-phenoxypolyethylene glycol and sodium dioctylsulfosuccinate. The "Norforks" and other preparations contain mercurial compounds which may turn out to be harmful. The future promises the development of products which will act to prevent fertilization by acting on the hyaluronidase and the acrosine of the spermatozoid, thus preventing it from penetrating the ovum. It would be best to find enzyme inhibitors which are

  17. SIMPLIFIED PREDICTIVE MODELS FOR CO₂ SEQUESTRATION PERFORMANCE ASSESSMENT RESEARCH TOPICAL REPORT ON TASK #3 STATISTICAL LEARNING BASED MODELS

    Mishra, Srikanta; Schuetter, Jared

    2014-11-01

    We compare two approaches for building a statistical proxy model (metamodel) for CO₂ geologic sequestration from the results of full-physics compositional simulations. The first approach involves a classical Box-Behnken or Augmented Pairs experimental design with a quadratic polynomial response surface. The second approach used a space-filling maxmin Latin Hypercube sampling or maximum entropy design with the choice of five different meta-modeling techniques: quadratic polynomial, kriging with constant and quadratic trend terms, multivariate adaptive regression spline (MARS) and additivity and variance stabilization (AVAS). Simulations results for CO₂ injection into a reservoir-caprock system with 9 design variables (and 97 samples) were used to generate the data for developing the proxy models. The fitted models were validated with using an independent data set and a cross-validation approach for three different performance metrics: total storage efficiency, CO₂ plume radius and average reservoir pressure. The Box-Behnken–quadratic polynomial metamodel performed the best, followed closely by the maximin LHS–kriging metamodel.

  20. Scaling up Dynamic Topic Models

    Bhadury, Arnab; Chen, Jianfei; Zhu, Jun; Liu, Shixia

    2016-01-01

    Dynamic topic models (DTMs) are very effective in discovering topics and capturing their evolution trends in time series data. To do posterior inference of DTMs, existing methods are all batch algorithms that scan the full dataset before each update of the model and make inexact variational approximations with mean-field assumptions. Due to a lack of a more scalable inference algorithm, despite the usefulness, DTMs have not captured large topic dynamics. This paper fills this research void, a...

  2. ADEX optimized adaptive controllers and systems from research to industrial practice

    Martín-Sánchez, Juan M

    2015-01-01

    This book is a didactic explanation of the developments of predictive, adaptive predictive and optimized adaptive control, including the latest methodology of adaptive predictive expert (ADEX) control, and their practical applications. It is focused on the stability perspective, used in the introduction of these methodologies, and is divided into six parts, with exercises and real-time simulations provided for the reader as appropriate. ADEX Optimized Adaptive Controllers and Systems begins with the conceptual and intuitive knowledge of the technology and derives the stability conditions to be verified by the driver block and the adaptive mechanism of the optimized adaptive controller to guarantee achievement of desired control performance. The second and third parts are centered on the design of the driver block and adaptive mechanism, which verify these stability conditions. The authors then proceed to detail the stability theory that supports predictive, adaptive predictive and optimized adaptive control m...

  4. Full-Scaled Advanced Systems Testbed: Ensuring Success of Adaptive Control Research Through Project Lifecycle Risk Mitigation

    Pavlock, Kate M.

    2011-01-01

    The National Aeronautics and Space Administration's Dryden Flight Research Center completed flight testing of adaptive controls research on the Full-Scale Advance Systems Testbed (FAST) in January of 2011. The research addressed technical challenges involved with reducing risk in an increasingly complex and dynamic national airspace. Specific challenges lie with the development of validated, multidisciplinary, integrated aircraft control design tools and techniques to enable safe flight in the presence of adverse conditions such as structural damage, control surface failures, or aerodynamic upsets. The testbed is an F-18 aircraft serving as a full-scale vehicle to test and validate adaptive flight control research and lends a significant confidence to the development, maturation, and acceptance process of incorporating adaptive control laws into follow-on research and the operational environment. The experimental systems integrated into FAST were designed to allow for flexible yet safe flight test evaluation and validation of modern adaptive control technologies and revolve around two major hardware upgrades: the modification of Production Support Flight Control Computers (PSFCC) and integration of two, fourth-generation Airborne Research Test Systems (ARTS). Post-hardware integration verification and validation provided the foundation for safe flight test of Nonlinear Dynamic Inversion and Model Reference Aircraft Control adaptive control law experiments. To ensure success of flight in terms of cost, schedule, and test results, emphasis on risk management was incorporated into early stages of design and flight test planning and continued through the execution of each flight test mission. Specific consideration was made to incorporate safety features within the hardware and software to alleviate user demands as well as into test processes and training to reduce human factor impacts to safe and successful flight test. This paper describes the research configuration

  5. Adapting an evidence-based model to retain adolescent study participants in longitudinal research.

    Davis, Erin; Demby, Hilary; Jenner, Lynne Woodward; Gregory, Alethia; Broussard, Marsha

    2016-02-01

    Maintaining contact with and collecting outcome data from adolescent study participants can present a significant challenge for researchers conducting longitudinal studies. Establishing an organized and effective protocol for participant follow-up is crucial to reduce attrition and maintain high retention rates. This paper describes our methods in using and adapting the evidence-based Engagement, Verification, Maintenance, and Confirmation (EVMC) model to follow up with adolescents 6 and 12 months after implementation of a health program. It extends previous research by focusing on two key modifications to the model: (1) the central role of cell phones and texting to maintain contact with study participants throughout the EVMC process and, (2) use of responsive two-way communication between staff and participants and flexible administration modes and methods in the confirmation phase to ensure that busy teens not only respond to contacts, but also complete data collection. These strategies have resulted in high overall retention rates (87-91%) with adolescent study participants at each follow-up data collection point without the utilization of other, more involved tracking measures. The methods and findings presented may be valuable for other researchers with limited resources planning for or engaged in collecting follow-up outcome data from adolescents enrolled in longitudinal studies.

  6. Lead Research and Development Activity for DOE's High Temperature, Low Relative Humidity Membrane Program (Topic 2)

    James Fenton, PhD; Darlene Slattery, PhD; Nahid Mohajeri, PhD

    2012-09-05

    The Department of Energy’s High Temperature, Low Relative Humidity Membrane Program was begun in 2006 with the Florida Solar Energy Center (FSEC) as the lead organization. During the first three years of the program, FSEC was tasked with developing non-Nafion® proton exchange membranes with improved conductivity for fuel cells. Additionally, FSEC was responsible for developing protocols for the measurement of in-plane conductivity, providing conductivity measurements for the other funded teams, developing a method for through-plane conductivity and organizing and holding semiannual meetings of the High Temperature Membrane Working Group (HTMWG). The FSEC membrane research focused on the development of supported poly[perfluorosulfonic acid] (PFSA) – Teflon membranes and a hydrocarbon membrane, sulfonated poly(ether ether ketone). The fourth generation of the PFSA membrane (designated FSEC-4) came close to, but did not meet, the Go/No-Go milestone of 0.1 S/cm at 50% relative humidity at 120 °C. In-plane conductivity of membranes provided by the funded teams was measured and reported to the teams and DOE. Late in the third year of the program, DOE used this data and other factors to decide upon the teams to continue in the program. The teams that continued provided promising membranes to FSEC for development of membrane electrode assemblies (MEAs) that could be tested in an operating fuel cell. FSEC worked closely with each team to provide customized support. A logic flow chart was developed and discussed before MEA fabrication or any testing began. Of the five teams supported, by the end of the project, membranes from two of the teams were easily manufactured into MEAs and successfully characterized for performance. One of these teams exceeded performance targets, while the other requires further optimization. An additional team developed a membrane that shows great promise for significantly reducing membrane costs and increasing membrane lifetime.

    2014-06-01

    Full Text Available The biomedical information environment is in a state of constant and rapid change due to the increase in research data and rapid technological advances. In Taiwan, few research has investigated the information literacy of biomedical graduate students. This exploratory study examined the information literacy abilities and training of biomedical graduate students in Taiwan. Semi-structured interviews based on the Association of College and Research Libraries Information Literacy Competency Standards for Science and Engineering/Technology were conducted with 20 molecular biological graduate students. The interview inquired about their information-seeking channels and information literacy education. The findings show that the biomedical graduate students developed a workable thesis topic with their advisors. Through various information-seeking channels and retrieval strategies, they obtained and critically evaluated information to address different information needs for their thesis research. Through seminars, annual conferences and papers, the interviewees were informed of current developments in their field. Subsequently, through written or oral communications, they were able to integrate and exchange the information. Most interviewees cared about the social, economic, legal, and ethical issues surrounding the use of information. College courses and labs were the main information literacy education environment for them to learn about research skills and knowledge. The study concludes four areas to address for the information literacy of biomedical graduate students, i.e., using professional information, using the current information, efficiency in assessing the domain information, and utilization of diverse information channels. Currently, the interviewees showed rather low usage of library resources, which is a concern for biomedical educators and libraries. [Article content in Chinese

    2010-04-01

    Full Text Available In this paper we present our research of online hot topic detection and label extraction method for our hot topic recommendation system. Using a new topical feature selection method, the feature space is compressed suitable for an online system. The tolerance rough set model is used to enriching the small set of topical feature words to a topical approximation space. According to the distance defined on the topical approximation space, the web pages are clustered into groups which will be merged with document overlap. The topic labels are extracted based on the approximation topical space enriched with the useful but high frequency topical words dropped by the clustering process. The experiments show that our method could generate more information abundant classes and more topical class labels, alleviate the topical drift caused by the non-topical and noise words.

  9. Topic Model for Graph Mining.

    Xuan, Junyu; Lu, Jie; Zhang, Guangquan; Luo, Xiangfeng

    2015-12-01

    Graph mining has been a popular research area because of its numerous application scenarios. Many unstructured and structured data can be represented as graphs, such as, documents, chemical molecular structures, and images. However, an issue in relation to current research on graphs is that they cannot adequately discover the topics hidden in graph-structured data which can be beneficial for both the unsupervised learning and supervised learning of the graphs. Although topic models have proved to be very successful in discovering latent topics, the standard topic models cannot be directly applied to graph-structured data due to the "bag-of-word" assumption. In this paper, an innovative graph topic model (GTM) is proposed to address this issue, which uses Bernoulli distributions to model the edges between nodes in a graph. It can, therefore, make the edges in a graph contribute to latent topic discovery and further improve the accuracy of the supervised and unsupervised learning of graphs. The experimental results on two different types of graph datasets show that the proposed GTM outperforms the latent Dirichlet allocation on classification by using the unveiled topics of these two models to represent graphs.

    Anderson, Ruth A; Bailey, Donald E; Wu, Bei; Corazzini, Kirsten; McConnell, Eleanor S; Thygeson, N Marcus; Docherty, Sharron L

    2015-01-01

    We propose the Adaptive Leadership Framework for Chronic Illness as a novel framework for conceptualizing, studying, and providing care. This framework is an application of the Adaptive Leadership Framework developed by Heifetz and colleagues for business. Our framework views health care as a complex adaptive system and addresses the intersection at which people with chronic illness interface with the care system. We shift focus from symptoms to symptoms and the challenges they pose for patients/families. We describe how providers and patients/families might collaborate to create shared meaning of symptoms and challenges to coproduce appropriate approaches to care. PMID:25647829

    Full Text Available 路徑搜尋網路(PFNet方法與社群偵測演算法經常被應用在研究主題的視覺化呈現與分析。PFNet方法能夠在保留原先網路的結構特性下,刪除大量不重要的連結線。社群偵測演算法則能夠將網路劃分成凝聚性子群。然而這兩種方法都有不足的地方:PFNet方法無法自動從輸入的網路上發現重要的子群,社群偵測演算法無法保證同一子群的節點會映射在鄰近的區域。本論文建議整合這兩種方法以減輕上述的問題:利用社群偵測演算法將PFNet方法產生的新網路劃分成子群。並且本研究也建議利用子群內的出現頻率較高的詞語做為研究主題的標示,讓結果分析與詮釋更加容易。本研究以臺灣資訊傳播學領域為範例,利用相關系所的碩士論文為分析資料。研究結果發現:整合PFNet方法和社群偵測演算法有利於從論文相關網路上發現代表重要研究主題的子群。子群內最高出現頻次的詞語大多和資訊傳播學以及其基礎領域的問題、方法、理論和技術非常相關,可以做為研究主題的標示。The Pathfinder network (PFNet method and the community detection algorithms both are methods which have been widely applied to visual presentation and analysis of research topics. The PFNet method can delete a large amount of insignificant links in networks but also retains the structural characteristics of the original networks, while the community detection algorithms are able to partition networks into a set of cohesive subgroups. However, each of the methods has its deficiencies. The PFNet method cannot automatically find out critical subgroups in input networks and the community detection algorithms do not guarantee nodes in the same subgroup able to be mapped in neighboring area. The integration of these two methods provides a way to alleviate the above problems: The output network from the PFNet method

  13. Reduced analysis and confirmatory research on co-adaptability theoretical solution to conflicting events in construction engineering projects

    2010-01-01

    The co-adaptability theoretical solution to conflicting events in construction engineering projects has three problems. First, the transformation of constraint conditions of theoretical solution is very difficult in practical engineering applications; second, some coefficients are difficult to be determined; third, there are overfull circular arithmetic operations involved in it. To resolve these problems, a new method to reduce the theoretical solution complications is proposed. By analyzing the operating mechanism of theoretical solution model, redundancies in the theoretical solution can be eliminated, and the ISM mapping with the co-adaptability solution can be set up. Based on this approach, a procedure to solve practical conflicting events in construction projects is established by replacing characteristic variables with mathematic variables. The research results show that the procedure can replace the co-adaptability theoretical solution effectively and solve practical conflicting events in construction projects.

    Zhendong Yin

    2013-01-01

    Full Text Available Satellite communication has become a modern indispensable means of communication. In order to reduce the BER in a maximum limit, the transmitting terminal of adaptive satellite communication technology can automatic select working frequency, data transmission rate and modulation mode. In this study, a simple and practical design of system based on the Signal-to-noise Ratio (SNR estimation scheme with adaptive modulation for satellite communication is presented. This system applies Maximum-likelihood (ML algorithm to estimate SNR. Simulation deduces the modulation mode switching threshold. In addition, the adaptive modulation switching threshold is the trade off between spectral efficiency and Bit Error Rate (BER. Furthermore, the modulation mode decision strategy should be considered to achieve the highest spectral efficiency and to maintain constant average BER. The design of an integrated SNR estimation and adaptive modulation mode decision system is highly challenging. Numerical results show that the design fulfills superior performance.

    Gutowski, William J.; Prusa, Joseph M.; Smolarkiewicz, Piotr K.

    2012-05-08

    demonstrated range of validity of soundproof models, showing that they are more broadly applicable than some had previously thought. Substantial testing of EULAG included application and extension of the Jablonowski-Williamson baroclinic wave test - an archetype of planetary weather - and further analysis of multi-scale interactions arising from collapse of temperature fronts in both the baroclinic wave test and simulations of the Held-Suarez idealized climate. These analyses revealed properties of atmospheric gravity waves not seen in previous work and further demonstrated the ability of EULAG to simulate realistic behavior over several orders of magnitude of length scales. Additional collaborative work enhanced capability for modeling atmospheric flows with adaptive moving meshes and demonstrated the ability of EULAG to move into petascale computing. 3b. CAM-EULAG Advances We have developed CAM-EULAG in collaboration with former project postdoc, now University of Cape Town Assistant Professor, Babatunde Abiodun. Initial study documented good model performance in aqua-planet simulations. In particular, we showed that the grid adaptivity (stretching) implemented in CAM-EULAG allows higher resolution in selected regions without causing anomalous behavior such as spurious wave reflection. We then used the stretched-grid version to analyze simulated extreme precipitation events in West Africa, comparing the precipitation and event environment with observed behavior. The model simulates fairly well the spatial scale and the interannual and intraseasonal variability of the extreme events, although its extreme precipitation intensity is weaker than observed. In addition, both observations and the simulations show possible forcing of extreme events by African easterly waves. 3c. Other Contributions Through our collaborations, we have made contributions to a wide range of outcomes. For research focused on terrestrial behavior, these have included (1) upwind schemes for gas dynamics

    Dan Wang

    2014-02-01

    Full Text Available This paper presents an adaptive controller equipped with a stiffness estimation method for a novel material-testing machine, in order to alleviate the performance depression caused by the stiffness variance of the tested specimen. The dynamic model of the proposed machine is built using the Kane method, and the kinematic model is established with a closed-form solution. The stiffness estimation method is developed based on the recursive least-squares method and the proposed stiffness equivalent matrix. Control performances of the adaptive controller are simulated in detail. The simulation results illustrate that the proposed controller can greatly improve the control performance of the target material-testing machine by online stiffness estimation and adaptive parameter tuning, especially in low-cycle fatigue (LCF and high-cycle fatigue (HCF tests.

    Arnstein, Paul M

    2013-07-01

    Topically applied analgesic therapies have been used throughout history to treat a variety of patient conditions that present with pain. Before modem pharmaceuticals became readily available, mud-based emollients, salves, cold therapies, and other natural remedies were often used. Now we have effective therapies and are developing advanced topical analgesics as we learn more about the physiology and pathophysiology of pain. The use of topical analgesics may be associated with fewer patient systemic side effects than are seen with oral, parenteral, or transdermally administered agents, making the topical route of administration attractive to prescribers and patients. With further refinement of existing drugs and the development of novel agents, topical analgesics may offer relief for treating patient pain conditions that are currently challenging to treat, such as pain resulting from burns, wound debridement, and pressure ulcers. Recognizing the value of a multimodal approach, topical analgesics may offer a therapeutic option that can become part of a comprehensive treatment plan for the patient. With continued advancements in targeted drug-delivery systems, topical analgesics may be able to provide a method to prevent or reverse the phenomena of peripheral and central sensitization, or the neuroplastic changes believed to be responsible for the transition from acute to chronic pain states in patients. For those patients at risk for developing chronic pain states, such as complex regional pain syndrome, the combination of cutaneous stimulation (achieved through rubbing during application) and analgesic effects produced by the drug itself may prevent the disabling pain that often emerges during the subacute phase of disease. In summary, better utilization of currently available topical analgesics and continued research promise to ensure that topical analgesics are, and will continue to be, important tools in the treatment of patients with resistant pain.

  4. A Framing Approach to Cross-disciplinary Research Collaboration: Experiences from a Large-scale Research Project on Adaptive Water Management

    Tharsi Taillieu

    2007-12-01

    Full Text Available Although cross-disciplinary research collaboration is necessary to achieve a better understanding of how human and natural systems are dynamically linked, it often turns out to be very difficult in practice. We outline a framing approach to cross-disciplinary research that focuses on the different perspectives that researchers from different backgrounds use to make sense of the issues they want to research jointly. Based on interviews, participants’ evaluations, and our own observations during meetings, we analyze three aspects of frame diversity in a large-scale research project. First, we identify dimensions of difference in the way project members frame the central concept of adaptive water management. Second, we analyze the challenges provoked by the multiple framings of concepts. Third, we analyze how a number of interventions (interactive workshops, facilitation, group model building, and concrete case contexts contribute to the connection and integration of different frames through a process of joint learning and knowledge construction.

  5. Topics on continua

    Macias, Sergio

    2005-01-01

    Specialized as it might be, continuum theory is one of the most intriguing areas in mathematics. However, despite being popular journal fare, few books have thoroughly explored this interesting aspect of topology. In Topics on Continua, Sergio Macías, one of the field's leading scholars, presents four of his favorite continuum topics: inverse limits, Jones's set function T, homogenous continua, and n-fold hyperspaces, and in doing so, presents the most complete set of theorems and proofs ever contained in a single topology volume. Many of the results presented have previously appeared only in research papers, and some appear here for the first time. After building the requisite background and exploring the inverse limits of continua, the discussions focus on Professor Jones''s set function T and continua for which T is continuous. An introduction to topological groups and group actions lead to a proof of Effros''s Theorem, followed by a presentation of two decomposition theorems. The author then offers an...

  9. Research on Improved Adaptive Control for Static Synchronous Compensator in Power System

    Chao Zhang

    2015-01-01

    Full Text Available This paper deals with the problems of “explosion of term,” uncertain parameter in static synchronous compensator (STATCOM system with nonlinear time-delay. An improved adaptive controller is proposed to enhance the transient stability of system states and reduce computational complexity of STATCOM control system. In contrast to backstepping control scheme in high order systems, the problem of “explosion of term” is avoided by designing dynamic surface controller. The low pass filter is included to allow a design where the model is not differentiated and thus has prevented the mathematical complexities effectively. In addition, unlike the traditional adaptive control schemes, the certainty equivalence principle is not required for estimating the uncertain parameter by system immersion and manifold invariant (I&I adaptive control. A smooth function is added to ensure that the estimation error converges to zero in finite time. The effectiveness of the proposed controller is verified by the simulations. Compared with adaptive backstepping and proportion integration differentiation (PID, the oscillation amplitudes of transient response are reduced by nearly half, and the time of reaching steady state is shortened by at least 11%.

    Goza, B. K.; Hunter, L.; Shaw, J. M.; Metevier, A. J.; Raschke, L.; Espinoza, E.; Geaney, E. R.; Reyes, G.; Rothman, D. L.

    2010-12-01

    This paper describes the interaction of four elements of social science as they have evolved in concert with the Center for Adaptive Optics Professional Development Program (CfAO PDP). We hope these examples persuade early-career scientists and engineers to include social science activities as they develop grant proposals and carry out their research. To frame our discussion we use a metaphor from astronomy. At the University of California Santa Cruz (UCSC), the CfAO PDP and the Educational Partnership Center (EPC) are two young stars in the process of forming a solar system. Together, they are surrounded by a disk of gas and dust made up of program evaluation, applied research, educational assessment, and pedagogy. An idea from the 2001 PDP intensive workshops program evaluation developed into the Assessing Scientific Inquiry and Leadership Skills (AScILS) applied research project. In iterative cycles, AScILS researchers participated in subsequent PDP intensive workshops, teaching social science while piloting AScILS measurement strategies. Subsequent "orbits" of the PDP program evaluation gathered ideas from the applied research and pedagogy. The denser regions of this disk of social science are in the process of forming new protoplanets as tools for research and teaching are developed. These tools include problem-solving exercises or simulations of adaptive optics explanations and scientific reasoning; rubrics to evaluate the scientific reasoning simulation responses, knowledge regarding inclusive science education, and student explanations of science/engineering inquiry investigations; and a scientific reasoning curriculum. Another applied research project is forming with the design of a study regarding how to assess engineering explanations. To illustrate the mutual shaping of the cross-disciplinary, intergenerational group of educational researchers and their projects, the paper ends with a description of the professional trajectories of some of the

A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human–environment interactions (for example, climate change, for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change in multi-actors contexts has progressively been

    2006-01-01

    The study of atomic physics propelled us into the quantum age in the early twentieth century and carried us into the twenty-first century with a wealth of new and, in some cases, unexplained phenomena. Topics in Atomic Physics provides a foundation for students to begin research in modern atomic physics. It can also serve as a reference because it contains material that is not easily located in other sources. A distinguishing feature is the thorough exposition of the quantum mechanical hydrogen atom using both the traditional formulation and an alternative treatment not usually found in textbooks. The alternative treatment exploits the preeminent nature of the pure Coulomb potential and places the Lenz vector operator on an equal footing with other operators corresponding to classically conserved quantities. A number of difficult to find proofs and derivations are included as is development of operator formalism that permits facile solution of the Stark effect in hydrogen. Discussion of the classical hydrogen...

  19. Research of an Adaptive Aggregation Routing Algorithm in Wireless Sensor Networks

    Xiangli Wang

    2012-07-01

    Full Text Available At present, most aggregation routing algorithms for WSNs assume that aggregation expends are so little as to be neglected. But with the growing demand for the collection of multimedia data, the aggregation expends are much larger and can’t be neglect. In view of this problem, this paper proposes an adaptive aggregation routing algorithm with the minimal energy consumption (RMEAAT. Firstly, it constructs an -balancing spanning tree on the basis of SPT and MST as the initial communication path. And then it defines the aggregation benefit with consideration of aggregation expend and transmission expend, and data are adaptively judged whether to aggregate at every node of -balancing spanning tree according to aggregation benefit in the process of transmission. Correspondingly, the initial transmission path is gradually improved in terms of the aggregation judgment. The simulation results show that RMEAAT algorithm has better performance in WSNs with different aggregation expends and fusion degrees.

    Jiang Changsheng; Zhang Chunyu; Zhu Liang

    2008-01-01

    A robust adaptive trajectory linearization control (RATLC) algorithm for a class of nonlinear systems with uncertainty and disturbance based on the T-S fuzzy system is presented. The unknown disturbance and uncertainty are estimated by the T-S fuzzy system, and a robust adaptive control law is designed by the Lyapunov theory. Irrespective of whether the dimensions of the system and the rules of the fuzzy system are large or small, there is only one parameter adjusting on line. Uniformly ultimately boundedness of all signals of the composite closed-loop system are proved by theory analysis. Finally, a numerical example is studied based on the proposed method. The simulation results demonstrate the effectiveness and robustness of the control scheme.

    FAN Xing; GU Wei-kang; YE Xiu-qing

    2005-01-01

    In multimedia conference, the capability of audio processing is basic and requires more for real-time criteria. In this article, we categorize and analyze the schemes, and provide several multipoint speech audio mixing schemes using weighted algorithm, which meet the demand of practical needs for real-time multipoint speech mixing, for which the ASW and AEW schemes are especially recommended. Applying the adaptive algorithms, the high-performance schemes we provide do not use the saturation operation widely used in multimedia processing. Therefore, no additional noise will be added to the output. The above adaptive algorithms have relatively low computational complexity and good hearing perceptibility. The schemes are designed for parallel processing, and can be easily implemented with hardware, such as DSPs, and widely applied in multimedia conference systems.

  7. Research on the adaptation of skeletal muscle to hypogravity: Past and future directions

    Riley, D. A.; Ellis, S.

    Our current understanding of hypogravity-induced atrophy of skeletal muscles is based primarily on studies comparing pre- and post-flight properties of muscles. Interpretations are necessarily qualified by the assumption that the stress of reentry and readjustment to terrestrial gravity do not alter the parameters being analyzed. The neuromuscular system is highly responsive to changes in functional demands and capable of rapid adaptation, making this assumption questionable. A reexamination of the changes in the connective tissue and synaptic terminals of soleus muscles from rats orbited in biosatellites and sampled postflight indicates that these structural alterations represent adaptative responses of the atrophic muscles to the increased workload of returning to 1 G, rather than hypogravity per se. The atrophy of weightlessness is postulated to result because muscles are both underloaded and used less often. Proper testing of this hypothesis requires quantitation of muscle function by monitoring electromyography, force output and length changes during the flight. Experiments conducted in space laboratories, like those being developed for the Space Shuttle, will avoid the complications of reentry before tissue sampling and allow time course studies of the rate of development of adaptive changes to zero gravity. Another area of great importance for future studies of muscle atrophy is inflight measurement of plasma levels of hormones and tissue receptor levels. Glucocorticoids, thyroid hormone and insulin exert dramatic regulatory influences on muscle structure. Prevention of neuromuscular atrophy becomes increasingly more important as spaceflights increase in duration. Definition of the atrophic mechanism is essential to developing means of preventing neuromuscular atrophy.

    2005-07-01

    Full Text Available Using narrative research methods with an emphasis on the value of practical theological wisdom and an awareness of postmodernism and social constructionism as paradigmatic context, the adaptation process of the Vermaak (pseudonym family after a move from South Africa to New Zealand, was explored.  Five major areas of their family life in which change occurred are discussed and their experience of God’s involvement in the process is articulated. This understanding is enriched by an interdisciplinary inquiry which highlighted the process and the importance of the motivation for an overseas move as a helpful or hindering factor for meaningful adaptation. A brief mention of possible physical, psychological and social consequences is followed by a few comments that might be helpful to others.  The Vermaak family managed to strike a balance between the continuation of their past story and embracing their new context. This fact provides a hopeful anticipated future.

  9. Syntactic Topic Models

    Boyd-Graber, Jordan

    2010-01-01

    The syntactic topic model (STM) is a Bayesian nonparametric model of language that discovers latent distributions of words (topics) that are both semantically and syntactically coherent. The STM models dependency parsed corpora where sentences are grouped into documents. It assumes that each word is drawn from a latent topic chosen by combining document-level features and the local syntactic context. Each document has a distribution over latent topics, as in topic models, which provides the semantic consistency. Each element in the dependency parse tree also has a distribution over the topics of its children, as in latent-state syntax models, which provides the syntactic consistency. These distributions are convolved so that the topic of each word is likely under both its document and syntactic context. We derive a fast posterior inference algorithm based on variational methods. We report qualitative and quantitative studies on both synthetic data and hand-parsed documents. We show that the STM is a more pred...

    Full Text Available Topic maps are an ISO standard (ISO 13250 that is used for presenting the information about information resources structures. The initial idea of this standard was raised in 1991 and due to its strength; it turned into an ISO standard. This paper investigates concepts and model of topic maps and aims to mention applications of this standard in library and information science (LIS realm. A topic map, as a type of document is defined as XML or SGML technically. Research show that this standard is compatible with some of LIS techniques and rules especially in knowledge organization, but it attempts to use these rules in the web. So it can be said that according to some challenges that LIS field faces in adapting traditional techniques for knowledge organization in the Web, topic maps standard can help in solving such problems and challenges and this is what some experts of LIS tried to do.

  12. Tracking topic birth and death in LDA.

    Wilson, Andrew T.; Robinson, David Gerald

    2011-09-01

    Most topic modeling algorithms that address the evolution of documents over time use the same number of topics at all times. This obscures the common occurrence in the data where new subjects arise and old ones diminish or disappear entirely. We propose an algorithm to model the birth and death of topics within an LDA-like framework. The user selects an initial number of topics, after which new topics are created and retired without further supervision. Our approach also accommodates many of the acceleration and parallelization schemes developed in recent years for standard LDA. In recent years, topic modeling algorithms such as latent semantic analysis (LSA)[17], latent Dirichlet allocation (LDA)[10] and their descendants have offered a powerful way to explore and interrogate corpora far too large for any human to grasp without assistance. Using such algorithms we are able to search for similar documents, model and track the volume of topics over time, search for correlated topics or model them with a hierarchy. Most of these algorithms are intended for use with static corpora where the number of documents and the size of the vocabulary are known in advance. Moreover, almost all current topic modeling algorithms fix the number of topics as one of the input parameters and keep it fixed across the entire corpus. While this is appropriate for static corpora, it becomes a serious handicap when analyzing time-varying data sets where topics come and go as a matter of course. This is doubly true for online algorithms that may not have the option of revising earlier results in light of new data. To be sure, these algorithms will account for changing data one way or another, but without the ability to adapt to structural changes such as entirely new topics they may do so in counterintuitive ways.

  13. Research of Ant Colony Optimized Adaptive Control Strategy for Hybrid Electric Vehicle

    Linhui Li

    2014-01-01

    Full Text Available Energy management control strategy of hybrid electric vehicle has a great influence on the vehicle fuel consumption with electric motors adding to the traditional vehicle power system. As vehicle real driving cycles seem to be uncertain, the dynamic driving cycles will have an impact on control strategy’s energy-saving effect. In order to better adapt the dynamic driving cycles, control strategy should have the ability to recognize the real-time driving cycle and adaptively adjust to the corresponding off-line optimal control parameters. In this paper, four types of representative driving cycles are constructed based on the actual vehicle operating data, and a fuzzy driving cycle recognition algorithm is proposed for online recognizing the type of actual driving cycle. Then, based on the equivalent fuel consumption minimization strategy, an ant colony optimization algorithm is utilized to search the optimal control parameters “charge and discharge equivalent factors” for each type of representative driving cycle. At last, the simulation experiments are conducted to verify the accuracy of the proposed fuzzy recognition algorithm and the validity of the designed control strategy optimization method.

  1. Adaptive Management of the Global Climate Problem. Bridging the Gap Between Climate Research and Climate Policy

    To date the Intergovernmental Panel on Climate Change (IPCC) has concerned itself with gathering a state of the art review of the science of climate change. While significant progress has been made in enhancing our integrated understanding of the climate system and the dynamics of the social systems that produce an array of potential greenhouse gases, it is also clear from the panel's reports how far the science community is from being able to present a dynamic and synoptic view of the climate system as a whole. Clear evidence of these complexities and uncertainties inherent in the climate system is evident in efforts aimed at designing robust policy interventions. In this paper, we argue that the adaptive management framework in ecosystem management may be a useful model for guiding how the IPCC can continue to be relevant both as a scientific establishment and as a policy-relevant scientific endeavor

  7. The Bridge from Text to Mind: Adapting Reader-Response Theory to Consumer Research.

    Scott, Linda M.

    1994-01-01

    Consumer research on advertising response has gradually separated the act of reading an ad from the acquisition of brand information. Because the advertising text is the pathway through which brand information is accessed, current models truncate the process that leads to response in a way that distorts our view of both advertising and the mind that reads it. This author proposes that reader-response theory would help researchers study the process of reading as an essential link between adver...

    Bozic, Mirjana; Man'ko, Margarita

    2009-09-01

    This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and

    邱云飞; 程亮

    2012-01-01

    Against the problem that Topic Detection and Tracking(TDT) can not deal with the short message texts on microblog which have strong randomness and non-standard terms effectively, a detecting method of sudden topics on microblog based on the dynamic sliding window is proposed. It includes the use of windows to extract the information with potential sudden, the use of normalized Term Frequeney-Inverse Doeument Frequeney(TF-IDF) function which is combined with semantic to compute feature weight and build Vector Space Model(VSM), the use of the main idea of Single-Pass clustering algorithm and then improving it in order to generate the final clustering. Experimental results show that the algorithm has an accurate result in sudden topic detection.%话题检测与跟踪模型不能很好地处理随意性强、用语不规范的微博短信息.为此,提出一种基于动态滑动窗口的微博突发话题检测方法.利用窗口提取具有潜在突发性的信息,采用结合语义的归一化词频·反文档频率函数计算特征权重,构建结合语义的空间向量模型,使用Single-Pass聚类算法思想对其加以改进,生成最终聚类.实验结果表明,该算法能获得较准确的突发话题检测结果.

    Topic extraction of web user opinions is an important way of web 2. 0 information analysis. How to analyze valuable informa-tion from miscellaneous user opinions is a challenging issue. Due to short information content and amount of web user opinions, the article put forward information analysis method based on Latent Dirichlet Allocation and HowNet knowledge base to extract net review topic. Firstly, to set up the corpus through textual tagging and semantic analysis of the reviews, then using HowNet to calculate semantic similari-ty of the corpus items and to reduce semantic repetition, finally, using Latent Dirichlet Allocation to map the topic and realize new review topic extraction.%网络用户评论的主题发现研究是Web2.0时代信息分析的重要方式,如何从冗杂的用户评论中分析出有价值的信息是研究的热点。针对网络用户评论信息内容短、信息量少的特征,提出基于LDA( latent Dirichlet alloca-tion)主题发现模型结合HowNet知识库进行信息分析的方法,对网络评论进行主题发现的研究。首先通过评论文本的词性标注、语义分析,形成语料库,然后利用HowNet对语料库中的词项进行语义相似度的计算,完成语义去重、合并,最后通过LDA主题模型将用户评论的内容映射到主题上,实现对用户评论信息主题的发现。

  14. The significance of 'hierarchy' in a research project on adoption and adaptation.

    Mander, R

    1999-06-01

    In the course of phenomenological research project focusing on the midwife's care of the mother who relinquishes her baby for adoption, hierarchy emerged repeatedly as a significant theme. This concept manifested itself both methodologically as well as thematically. In methodological terms, hierarchy first became apparent during the planning phase in the selection of the research design: at this point it took the form of the distinction between quantitative and qualitative research design. In the course of applying for research access the same attitudes re-emerged in the gatekeepers' responses to the research design which had been chose. Later, during the field work, hierarchy appeared in the course of the interviews, in the form of the unequal balance of power between the interviewer and the informant. Specific tactics were required to overcome the likelihood of hierarchy affecting the data at this stage. Eventually this concept was raised by the informants, who included both relinquishing mothers an midwives, and became a major theme. The informants' use of hierarchy to explain the unselfishness of relinquishment proved to be one of a number of strategies which facilitated coping either with the experience of relinquishment or with caring for a women going through that experience. The conclusion which emerges is that hierarchy features in many aspects of life. While it may be beneficial when applied to certain situations to facilitate coping, in other circumstances it may be less than positive. PMID:10703416

  17. Research on giant magnetostrictive micro-displacement actuator with self-adaptive control algorithm

    Giant magnetostrictive micro-displacement actuator has some unique characteristics, such as big output torque and high precision localization which can be in the nanometer scale. Because the relation between input magnetic field and output strain of giant magnetostrictive micro-displacement actuator exhibits hysteresis and eddy flow, the actuator has to be controlled and used in low input frequency mode or in static mode. When the actuator is controlled with a high input frequency (above 100 Hz), the output strain will exhibit strong nonlinearity. This paper found hysteresis and nonlinearity dynamic transfer function of the actuator based on Jiles-Atherton hysteresis model. The output strain of Jiles-Atherton hystersis model can reflect real output of actuator corresponding to the real input magnetic field, and this has been verified by experiment. Against the nonlinearity generated by hysteresis and eddy flow in this paper, the output strain of actuator is used for feedback to control system, and the control system adopted self-adaptive control algorithm, the ideal input and output model of actuator is used for a reference model and a hysteresis transfer function for the actuator real model. Through experiment, it has been verified that this algorithm can improve the dynamic frequency of the giant magnetostrictive micro-displacement actuator and guarantee high precision localization and linearity between the input magnetic field and output strain of the actuator at the same time

  18. NATO Advanced Research Institute on Adaptive Control of Ill-Defined Systems

    Rissland, Edwina; Arbib, Michael

    1984-01-01

    There are some types of complex systems that are built like clockwork, with well-defined parts that interact in well-defined ways, so that the action of the whole can be precisely analyzed and anticipated with accuracy and precision. Some systems are not themselves so well-defined, but they can be modeled in ways that are like trained pilots in well-built planes, or electrolyte balance in healthy humans. But there are many systems for which that is not true; and among them are many whose understanding and control we would value. For example, the model for the trained pilot above fails exactly where the pilot is being most human; that is, where he is exercising the highest levels of judgment, or where he is learning and adapting to new conditions. Again, sometimes the kinds of complexity do not lead to easily analyzable models at all; here we might include most economic systems, in all forms of societies. There are several factors that seem to contribute to systems being hard to model, understand, or control. ...

  19. Climate change adaptation : planning for BC

    This paper explored climate change challenges facing British Columbia in the context of 9 topical issues, notably biodiversity, extreme events, energy, water supply, crop adaptation, health risks, sea level rise, population dynamics and new technologies. Each issue was summarized in terms of threats, current responses in British Columbia and precedents being set in Canada. The key principles of adaptation to climate change were also reviewed. In addition, the paper explored ways to adopt smart adaptation strategies-policy responses to climate change that cut across all major government functions, such as infrastructure, energy, water, economic development, resource management and agriculture. The paper emphasized that strategies that respond to the climate challenge should acknowledge the links between adaptation and mitigation, or emissions reduction. Both concepts need major investment in research, education and infrastructure to support comprehensive, effective responses. refs., tabs., figs

  20. Efficacy and tolerance of the topical application of potassium hydroxide (10% and 15% in the treatment of molluscum contagiosum: Randomized clinical trial: Research protocol

    Galindo Gisela

    2011-10-01

    Full Text Available Abstract Background Molluscum contagiosum is a non-severe pediatric viral infection. Because it is highly contagious and current treatments have negative aesthetic and psychological effects, we want to test an alternative treatment in the primary care setting, consisting of two different concentrations of potassium hydroxide solution. Methods/design The study design is a double-blind, randomized clinical trial, using three types of topical treatment. The treatment consist of daily applications of potassium hydroxide (KOH in aqueous solution at 10% and 15% concentration, and a placebo administered in the control group. Four follow-up visits (at 15, 30, 45 and 60 days are planned to evaluate treatment effectiveness and patient tolerance. The main outcome measure of the trial will be the healing rate, defined as lesion disappearance in the affected zones after the topic application of the experimental treatment. Secondary measures will be the principal characteristics and evolution of the affected zone (surface area, number of lesions, size and density of lesions, treatment tolerance (hyperpigmentation, itching, burning, pain, recurrence rate and the natural evolution of lesions in the control group. Discussion KOH can potentially be an effective and safe treatment for MC in primary care, and can also reduce referrals to dermatologists and hospital pediatric departments. In addition, KOH may be a valid and less expensive alternative to current invasive treatments (surgical excision. Trial Registration ClinicalTrials.gov: NCT01348386

  4. From ships in the night to exchanges in the piazza: Renegotiating the researcher-stakeholder nexus in climate adaptation

    Jackson, S. T.

    2015-12-01

    A substantial divide remains between the communities of research, embedded largely in universities and science agencies, and the communities of practice, comprising the natural-resource managers and other decision-makers in diverse federal, state, local, and tribal agencies and in private-sector enterprises and organizations. In spite of clear needs and best intentions, engagement among the respective communities is imperfect; researchers and stakeholders are often like ships passing in the night, exchanging brief, cryptic signals. A variety of boundary organizations have been developed to facilitate the communications, and a number of successful models for researcher-stakeholder exchange and engagement have been applied. At least two substantial challenges remain. First, how can the successes be scaled up and proliferated to meet the vast demands posed by climate adaptation? Second, how can the various boundary organizations most effectively foster this expansion, individually and collectively? Meeting these challenges will require coordination among the respective organizations, changes in the cultures of research and management, and careful assessment of process and outcomes.

  7. Natural resource mitigation, adaptation and research needs related to climate change in the Great Basin and Mojave Desert

    Hughson, Debra L.; Busch, David E.; Davis, Scott; Finn, Sean P.; Caicco, Steve; Verburg, Paul S.J.

    2011-01-01

    This report synthesizes the knowledge, opinions, and concerns of many Federal and State land managers, scientists, stakeholders, and partners from a workshop, held at the University of Nevada, Las Vegas, on April 20-22, 2010. Land managers, research scientists, and resource specialists identified common concerns regarding the potential effects of climate change on public lands and natural resources in the Great Basin and Mojave Desert and developed recommendations for mitigation, adaptation, and research needs. Water and, conversely, the effects of drought emerged as a common theme in all breakout sessions on terrestrial and aquatic species at risk, managing across boundaries, monitoring, and ecosystem services. Climate change models for the southwestern deserts predict general warming and drying with increasing precipitation variability year to year. Scientists noted that under these changing conditions the past may no longer be a guide to the future in which managers envision increasing conflicts between human water uses and sustaining ecosystems. Increasing environmental stress also is expected as a consequence of shifting ecosystem boundaries and species distributions, expansion of non-native species, and decoupling of biotic mutualisms, leading to increasingly unstable biologic communities. Managers uniformly expressed a desire to work across management and agency boundaries at a landscape scale but conceded that conflicting agency missions and budgetary constraints often impede collaboration. More and better science is needed to cope with the effects of climate change but, perhaps even more important is the application of science to management issues using the methods of adaptive management based on long-term monitoring to assess the merits of management actions. Access to data is essential for science-based land management. Basic inventories, spatial databases, baseline condition assessments, data quality assurance, and data sharing were identified as top

  8. Research on the adaptation of skeletal muscle to hypogravity Past and future directions

    Riley, D. A.; Ellis, S.

    1983-01-01

    The results of previous research on the cellular effects of microgravity on rat tissue are reviewed and areas of future necessary research are identified. The rats were flown on board Cosmos 605, 782, and 936. Postflight tissue analyses revealed increases in connective tissue cells and focal disruption of muscle fibers due to the microgravity environment of space. Evidence has been found for muscular and neural changes occurring as a result of reentry stresses. It is suggested that a data base be established for quantizing muscle function with electromyography, measurements of force output, and length measurement. The data can serve as a reference for comparisons with data obtained in orbiting laboratories such as the Spacelab. The experiments will have a goal of defining and preventing the mechanism of neuromuscular atrophy.

    SinglePass is a very common text clustering algorithm, which is widely used in topic detection and tracking. But in process of SinglePass algorithm, clustering result is not satisfactory, and furthermore, similarity matching reduces processing speed. Focusing on the two defects, the idea of reconstructing text is put forward, which considers the typical features of a topic as theme part and the content as details part through the reorganization of the forum or web information. On this basis, SinglePass clustering algorithm is improved. The results of the experiment prove that this method can solve the problem of sparse sample characteristics effectively, detect network hot topics timely and accurately, display the hierarchical structure at the same time.%SinglePass聚类算法是话题发现中最常用的文本聚类算法,且广泛地用于话题检测和跟踪中. 但它的聚类结果并不理想,此外,SinglePass在对报道与话题进行相似度匹配时导致了处理速度的降低. 基于这2个问题,本研究提出了一种文本重构思想. 即通过对论坛或网页信息的再组织,将和话题相关的主要信息集中在一起形成主题块,其余的部分形成细节块.在此基础上,对SinglePass聚类算法进行了改进. 实验结果证明:改进的SinglePass聚类算法有效地解决了文本特征矩阵稀疏的问题,并能够准确并及时地识别网络中的热点话题,同时展示话题的层次性结构.

    With increasing numbers of organizations automating their business processes by using workflow systems, security aspects of workflow systems has become a heavily researched area. Also, most workflow processes nowadays need to be adaptive, i.e., constantly changing, to meet changing business conditions. However, little attention has been paid to integrating Security and Adaptive Workflow. In this paper, we investigate this important research topic, with emphasis on Role Based Access Control (R...

    2009-07-01

    Full Text Available Abstract Background The SRS-22 is a valid instrument for the assessment of the health related quality of life of patients with Idiopathic scoliosis. The SRS-22 questionnaire was developed in USA and has been widely used in the English speaking countries. Recently it has been translated and validated in many other languages. The purpose of this study is to evaluate the reliability and validity of the adapted Greek version of the refined Scoliosis Research Society-22 Questionnaire. Methods Following the steps of cross – cultural adaptation the adapted Greek version of the SRS-22 questionnaire and a validated Greek version of the SF-36 questionnaire were mailed to 68 patients treated surgically for Idiopathic Scoliosis. 51 out of the 68 patients returned the 1st set of questionnaires, while a second set was emailed to 30 randomly selected patients of the first time responders. 20 out of the 30 patients returned the 2nd set. The mean age at the time of operation was16,2 years and the mean age at the time of evaluation was 21,2 years. Descriptive statistics for content analysis were calculated. Reliability assessment was determined by estimating Cronbach's α and intraclass correlation coefficient (ICC respectively. Concurrent validity was evaluated by comparing SRS-22 domains with relevant domains in the SF-36 questionnaire using Pearson's Correlation Coefficient (r. Results The calculated Cronbach's α of internal consistency for three of the corresponding domains (pain 0.85; mental health 0.87; self image 0.83 were very satisfactory and for two domains (function/activity 0.72 and satisfaction 0.67 were good. The ICC of all domains of SRS-22 questionnaire was high (ICC>0.70, demonstrating very satisfactory or excellent test/retest reproducibility. Considering concurrent validity all correlations were found to be statistically significant at the 0.01 level among related domains and generally demonstrated high correlation coefficient.

  15. Research on evaluations of several grey relational models adapt to grey relational axioms

    Xie Naiming; Liu Sifeng

    2009-01-01

    Grey relational analysis is an important part of the grey systems theory, and it is the basis of the grey clustering analysis, grey decision-making and grey controlling. To research whether grey relational models satisfy the four grey relational theorems, several kinds of grey relational models are commented. Some problems including the properties of normality, pair symmetry and wholeness are discussed. The phenomenon that the lower value of almost each grey relational model is not equal to zero is proved. The contradiction problems between the properties of wholeness and pair symmetry are verified. Finally, several propositions are constructed to explain the above problems.

    1998-01-01

    Full Text Available Pictorial stimuli and words have been widely used to evaluate mnemonic processes in clinical settings, neuropsychological investigations, as well as in studies on the mechanisms underlying the phenomena of memory. However, there seem to be few studies of standardisation of pictures for research in this field. The present paper aimed at adapting the use of a set of pictures standardised for English speaking subjects for Portuguese speakers. Name agreement of 150 pictures was assessed in 100 high-school students. Ninety pictures were found to present the same name for over 90 subjects. Results yield data that may help create more controlled tests for the study of memory for pictorial stimuli in Brazil.

  3. Topical treatment of melasma

    Bandyopadhyay Debabrata

    2009-01-01

    Full Text Available Melasma is a common hypermelanotic disorder affecting the face that is associated with considerable psychological impacts. The management of melasma is challenging and requires a long-term treatment plan. In addition to avoidance of aggravating factors like oral pills and ultraviolet exposure, topical therapy has remained the mainstay of treatment. Multiple options for topical treatment are available, of which hydroquinone (HQ is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin. Topical medications modify various stages of melanogenesis, the most common mode of action being inhibition of the enzyme, tyrosinase. Combination therapy is the preferred mode of treatment for the synergism and reduction of untoward effects. The most popular combination consists of HQ, a topical steroid, and retinoic acid. Prolonged HQ usage may lead to untoward effects like depigmentation and exogenous ochronosis. The search for safer alternatives has given rise to the development of many newer agents, several of them from natural sources. Well-designed controlled clinical trials are needed to clarify their role in the routine management of melasma.

  5. Direct adaptive control for nonlinear uncertain dynamical systems

    Hayakawa, Tomohisa

    In light of the complex and highly uncertain nature of dynamical systems requiring controls, it is not surprising that reliable system models for many high performance engineering and life science applications are unavailable. In the face of such high levels of system uncertainty, robust controllers may unnecessarily sacrifice system performance whereas adaptive controllers are clearly appropriate since they can tolerate far greater system uncertainty levels to improve system performance. In this dissertation, we develop a Lyapunov-based direct adaptive and neural adaptive control framework that addresses parametric uncertainty, unstructured uncertainty, disturbance rejection, amplitude and rate saturation constraints, and digital implementation issues. Specifically, we consider the following research topics; direct adaptive control for nonlinear uncertain systems with exogenous disturbances; robust adaptive control for nonlinear uncertain systems; adaptive control for nonlinear uncertain systems with actuator amplitude and rate saturation constraints; adaptive reduced-order dynamic compensation for nonlinear uncertain systems; direct adaptive control for nonlinear matrix second-order dynamical systems with state-dependent uncertainty; adaptive control for nonnegative and compartmental dynamical systems with applications to general anesthesia; direct adaptive control of nonnegative and compartmental dynamical systems with time delay; adaptive control for nonlinear nonnegative and compartmental dynamical systems with applications to clinical pharmacology; neural network adaptive control for nonlinear nonnegative dynamical systems; passivity-based neural network adaptive output feedback control for nonlinear nonnegative dynamical systems; neural network adaptive dynamic output feedback control for nonlinear nonnegative systems using tapped delay memory units; Lyapunov-based adaptive control framework for discrete-time nonlinear systems with exogenous disturbances

    2010-01-01

    This title adopts the view that physics is the primary driving force behind a number of developments in mathematics. Previously, science and mathematics were part of natural philosophy and many mathematical theories arose as a result of trying to understand natural phenomena. This situation changed at the beginning of last century as science and mathematics diverged. These two fields are collaborating once again; 'Topics in Mathematical Physics' takes the reader through this journey. The author discusses topics where the interaction of physical and mathematical theories has led to new points o

  17. Innovative and adaptive technologies in decommissioning of nuclear facilities. Final report of a coordinated research project 2004-2008

    There are dozens of old reactors and other nuclear facilities worldwide that are either being actively dismantled or are candidates for decommissioning in the near term. A significant proportion of these facilities are situated in Member States or institutions that do not have adequate expertise and technologies for planning and implementing state of the art decommissioning projects. The technology selection process is critical in that regard. The main objective of the IAEA technical activities on decommissioning is to promote the exchange of lessons learned in order to improve the technologies, thereby contributing to successful planning and implementation of decommissioning. This should be achieved through a better understanding of the decision making process in technology comparison and selection and relevant issues affecting the entire decommissioning process. The specific objectives of the Coordinated Research Project (CRP) on Innovative and Adaptive Technologies in Decommissioning of Nuclear Facilities include the following general aspects: (a) To establish methodologies and data needs for developing concepts and approaches relevant to technology comparison and selection in decommissioning; (b) To improve and expand the database on applications and performance of various types of decommissioning technologies; (c) To address specific issues for individual decommissioning technologies and generate data relevant to their comparison and selection. It is also expected that this project, and in particular the papers collected in this TECDOC, will draw Member States' attention to the practicality and achievability of timely planning and implementation of decommissioning, especially for many smaller projects. Concluding reports that summarized the work undertaken under the aegis of the CRP were presented at the third and final research coordination meeting held in Rez, Czech Republic, 3-7 December 2007, and collected in this technical publication.

  20. Differential Topic Models.

    Chen, Changyou; Buntine, Wray; Ding, Nan; Xie, Lexing; Du, Lan

    2015-02-01

    In applications we may want to compare different document collections: they could have shared content but also different and unique aspects in particular collections. This task has been called comparative text mining or cross-collection modeling. We present a differential topic model for this application that models both topic differences and similarities. For this we use hierarchical Bayesian nonparametric models. Moreover, we found it was important to properly model power-law phenomena in topic-word distributions and thus we used the full Pitman-Yor process rather than just a Dirichlet process. Furthermore, we propose the transformed Pitman-Yor process (TPYP) to incorporate prior knowledge such as vocabulary variations in different collections into the model. To deal with the non-conjugate issue between model prior and likelihood in the TPYP, we thus propose an efficient sampling algorithm using a data augmentation technique based on the multinomial theorem. Experimental results show the model discovers interesting aspects of different collections. We also show the proposed MCMC based algorithm achieves a dramatically reduced test perplexity compared to some existing topic models. Finally, we show our model outperforms the state-of-the-art for document classification/ideology prediction on a number of text collections. PMID:26353238

  1. Contrastive topics decomposed

    Michael Wagner

    2012-12-01

    Full Text Available The analysis of contrastive topics introduced in Büring 1997b and further developed in Büring 2003 relies on distinguishing two types of constituents that introduce alternatives: the sentence focus, which is marked by a FOC feature, and the contrastive topic, which is marked by a CT feature. A non-compositional rule of interpretation that refers to these features is used to derive a topic semantic value, a nested set of sets of propositions. This paper presents evidence for a correlation between the restrictive syntax of nested focus operators and the syntax of contrastive topics, a correlation which is unexpected under this analysis. A compositional analysis is proposed that only makes use of the flatter focus semantic values introduced by focus operators. The analysis aims at integrating insights from the original analysis while at the same time capturing the observed syntactic restrictions. http://dx.doi.org/10.3765/sp.5.8 BibTeX info

  5. Multiple Adaptations and Content-Adaptive FEC Using Parameterized RD Model for Embedded Wavelet Video

    Yu, Ya-Huei; Ho, Chien-Peng; Tsai, Chun-Jen

    2007-12-01

    Scalable video coding (SVC) has been an active research topic for the past decade. In the past, most SVC technologies were based on a coarse-granularity scalable model which puts many scalability constraints on the encoded bitstreams. As a result, the application scenario of adapting a preencoded bitstream multiple times along the distribution chain has not been seriously investigated before. In this paper, a model-based multiple-adaptation framework based on a wavelet video codec, MC-EZBC, is proposed. The proposed technology allows multiple adaptations on both the video data and the content-adaptive FEC protection codes. For multiple adaptations of video data, rate-distortion information must be embedded within the video bitstream in order to allow rate-distortion optimized operations for each adaptation. Experimental results show that the proposed method reduces the amount of side information by more than 50% on average when compared to the existing technique. It also reduces the number of iterations required to perform the tier-2 entropy coding by more than 64% on average. In addition, due to the nondiscrete nature of the rate-distortion model, the proposed framework also enables multiple adaptations of content-adaptive FEC protection scheme for more flexible error-resilient transmission of bitstreams.

  7. Practical considerations for adaptive trial design and implementation

    Pinheiro, José; Kuznetsova, Olga

    2014-01-01

    This edited volume is a definitive text on adaptive clinical trial designs from creation and customization to utilization. As this book covers the full spectrum of topics involved in the adaptive designs arena, it will serve as a valuable reference for researchers working in industry, government and academia. The target audience is anyone involved in the planning and execution of clinical trials, in particular, statisticians, clinicians, pharmacometricians, clinical operation specialists, drug supply managers, and infrastructure providers.  In spite of the increased efficiency of adaptive trials in saving costs and time, ultimately getting drugs to patients sooner, their adoption in clinical development is still relatively low.  One of the chief reasons is the higher complexity of adaptive design trials as compared to traditional trials. Barriers to the use of clinical trials with adaptive features include the concerns about the integrity of study design and conduct, the risk of regulatory non-acceptance, t...

  8. A Survey On Interactivity in Topic Models

    Patrik Ehrencrona Kjellin

    2016-04-01

    Full Text Available Trying to make sense and gain deeper insight from large sets of data is becoming a task very central to computer science in general. Topic models, capable of uncovering the semantic themes pervading through large collections of documents, have seen a surge in popularity in recent years. However, topic models are high level statistical tools; their output is given in terms of probability distributions, suited neither for simple interpretation nor deep analysis. Interpreting the fitted topic models in an intuitive manner requires visual and interactive tools. Additionally, some measure of human interaction is typically required for refining the output offered by such models. In the research, this area remains relatively unexplored – only recently has this aspect been receiving more attention. In this paper, the literature is surveyed as it pertains to interactivity and visualisation within the context of topic models, with the goal of finding current research trends in this area.

    This study, identifies and assesses system approaches in order to prioritize research needs for the capture and non-atmospheric sequestering of a significant portion of the carbon dioxide (CO{sub 2}) emitted from fossil fuel-fired electric power plants (US power plants presently produce about 7% of the world`s CO{sub 2} emissions). The study considers capture technologies applicable either to existing plants or to those that optimistically might be demonstrated on a commercial scale over the next twenty years. The research needs that have high priority in establishing the technical, environmental, and economic feasibility of large-scale capture and disposal of CO{sub 2} from electric power plants are:(1) survey and assess the capacity, cost, and location of potential depleted gas and oil wells that are suitable CO{sub 2} repositories (with the cooperation of the oil and gas industry); (2) conduct research on the feasibility of ocean disposal, with objectives of determining the cost, residence time, and environmental effects for different methods of CO{sub 2} injection; (3) perform an in-depth survey of knowledge concerning the feasibility of using deep, confined aquifers for disposal and, if feasible, identify potential disposal locations (with the cooperation of the oil and gas industry); (4) evaluate, on a common basis, system and design alternatives for integration of CO{sub 2} capture systems with emerging and advanced technologies for power generation; and prepare a conceptual design, an analysis of barrier issues, and a preliminary cost estimate for pipeline networks necessary to transport a significant portion of the CO{sub 2} to potentially feasible disposal locations.

  14. A Many-Objective Approach to Developing Adaptive Water Supply Portfolios in the 'Research Triangle' Region of North Carolina

    Zeff, H. B.; Kasprzyk, J. R.; Reed, P. M.; Characklis, G. W.

    2012-12-01

    This study uses many-objective evolutionary optimization to quantify the tradeoffs water utilities face when developing flexible water shortage response plans. Alternatives to infrastructure development, such as temporary demand management programs and inter-utility water transfer agreements, allow local water providers to develop portfolios of water supply options capable of adapting to changing hydrologic conditions and growing water demand. The extent to which these options are implemented will be determined by a number of conflicting operational and financial considerations. An integrated reservoir simulation model including four large water utilities in the 'Research Triangle' region of North Carolina is used to evaluate the potential tradeoffs resulting from regional demands on shared infrastructure, customer concerns, and the financial uncertainty caused by the intermittent and irregular nature of drought. Instead of providing one optimal solution, multi-objective evolutionary algorithms (MOEAs) use the concept of non-dominations to discover a set of portfolio options in which no solution is inferior to any other solution in all objectives. Interactive visual analytics enable water providers to explore these tradeoffs and develop water shortage response plans tailored to their individual circumstances. The simulation model is evaluated under a number of different formulations to help identify and visualize the impacts of water efficiency, revenue/cost variability, consumer effects, and inter-utility cooperation. The different problems are formulated by adding portfolio options and objectives in such a way that the lower dimensional problem formulations are sub-sets of the full formulation. The full formulation considers reservoir reliability, water use restriction frequency, total water transfer allotment, total costs, revenue/cost variability, and additional consumer losses during restrictions. The simulation results highlight the inadequacy of lower order

    Yeh, Lindsey; Bonati, Lauren Meshkov; Silverberg, Nanette B

    2016-06-01

    Topical retinoids are currently approved by the US Food and Drug Administration for the treatment of acne vulgaris in nonpregnant, nonlactating patients 12 years of age and older. Their efficacy, safety, and tolerability are well documented for inflammatory and noninflammatory acne with studies repeatedly demonstrating a decrease in the number of lesions, significant improvement in acne severity, improvement in the cosmetic appearance of acne, and the prevention of acne lesions through microcomedone formation. There is some variability between prescription retinoid products regarding efficacy, safety, and tolerability; with erythema, peeling, and dryness being common, potential side effects. Due to their efficacious and safe profile, topical retinoids remain the first-line treatment for acne vulgaris. PMID:27416308

  3. The use of fiber Bragg grating sensors in biomechanics and rehabilitation applications: the state-of-the-art and ongoing research topics.

    Al-Fakih, Ebrahim; Abu Osman, Noor Azuan; Mahamd Adikan, Faisal Rafiq

    2012-01-01

    In recent years, fiber Bragg gratings (FBGs) are becoming increasingly attractive for sensing applications in biomechanics and rehabilitation engineering due to their advantageous properties like small size, light weight, biocompatibility, chemical inertness, multiplexing capability and immunity to electromagnetic interference (EMI). They also offer a high-performance alternative to conventional technologies, either for measuring a variety of physical parameters or for performing high-sensitivity biochemical analysis. FBG-based sensors demonstrated their feasibility for specific sensing applications in aeronautic, automotive, civil engineering structure monitoring and undersea oil exploration; however, their use in the field of biomechanics and rehabilitation applications is very recent and its practicality for full-scale implementation has not yet been fully established. They could be used for detecting strain in bones, pressure mapping in orthopaedic joints, stresses in intervertebral discs, chest wall deformation, pressure distribution in Human Machine Interfaces (HMIs), forces induced by tendons and ligaments, angles between body segments during gait, and many others in dental biomechanics. This article aims to provide a comprehensive overview of all the possible applications of FBG sensing technology in biomechanics and rehabilitation and the status of ongoing researches up-to-date all over the world, demonstrating the FBG advances over other existing technologies.

  7. Topics in Banach space theory

    Albiac, Fernando

    2016-01-01

    This text provides the reader with the necessary technical tools and background to reach the frontiers of research without the introduction of too many extraneous concepts. Detailed and accessible proofs are included, as are a variety of exercises and problems. The two new chapters in this second edition are devoted to two topics of much current interest amongst functional analysts: Greedy approximation with respect to bases in Banach spaces and nonlinear geometry of Banach spaces. This new material is intended to present these two directions of research for their intrinsic importance within Banach space theory, and to motivate graduate students interested in learning more about them. This textbook assumes only a basic knowledge of functional analysis, giving the reader a self-contained overview of the ideas and techniques in the development of modern Banach space theory.

  8. Synergetics introduction and advanced topics

    Haken, Hermann

    2004-01-01

    This book is an often-requested reprint of two classic texts by H. Haken: "Synergetics. An Introduction" and "Advanced Synergetics". Synergetics, an interdisciplinary research program initiated by H. Haken in 1969, deals with the systematic and methodological approach to the rapidly growing field of complexity. Going well beyond qualitative analogies between complex systems in fields as diverse as physics, chemistry, biology, sociology and economics, Synergetics uses tools from theoretical physics and mathematics to construct an unifying framework within which quantitative descriptions of complex, self-organizing systems can be made. This may well explain the timelessness of H. Haken's original texts on this topic, which are now recognized as landmarks in the field of complex systems. They provide both the beginning graduate student and the seasoned researcher with solid knowledge of the basic concepts and mathematical tools. Moreover, they admirably convey the spirit of the pioneering work by the founder of ...

  12. Simplified Predictive Models for CO2 Sequestration Performance Assessment: Research Topical Report on Task #4 - Reduced-Order Method (ROM) Based Models

    Mishra, Srikanta; Jin, Larry; He, Jincong; Durlofsky, Louis

    2015-06-30

    Reduced-order models provide a means for greatly accelerating the detailed simulations that will be required to manage CO2 storage operations. In this work, we investigate the use of one such method, POD-TPWL, which has previously been shown to be effective in oil reservoir simulation problems. This method combines trajectory piecewise linearization (TPWL), in which the solution to a new (test) problem is represented through a linearization around the solution to a previously-simulated (training) problem, with proper orthogonal decomposition (POD), which enables solution states to be expressed in terms of a relatively small number of parameters. We describe the application of POD-TPWL for CO2-water systems simulated using a compositional procedure. Stanford’s Automatic Differentiation-based General Purpose Research Simulator (AD-GPRS) performs the full-order training simulations and provides the output (derivative matrices and system states) required by the POD-TPWL method. A new POD-TPWL capability introduced in this work is the use of horizontal injection wells that operate under rate (rather than bottom-hole pressure) control. Simulation results are presented for CO2 injection into a synthetic aquifer and into a simplified model of the Mount Simon formation. Test cases involve the use of time-varying well controls that differ from those used in training runs. Results of reasonable accuracy are consistently achieved for relevant well quantities. Runtime speedups of around a factor of 370 relative to full- order AD-GPRS simulations are achieved, though the preprocessing needed for POD-TPWL model construction corresponds to the computational requirements for about 2.3 full-order simulation runs. A preliminary treatment for POD-TPWL modeling in which test cases differ from training runs in terms of geological parameters (rather than well controls) is also presented. Results in this case involve only small differences between

  14. Collaboratively Architecting a Scalable and Adaptable Petascale Infrastructure to Support Transdisciplinary Scientific Research for the Australian Earth and Environmental Sciences

    Wyborn, L. A.; Evans, B. J. K.; Pugh, T.; Lescinsky, D. T.; Foster, C.; Uhlherr, A.

    2014-12-01

    The National Computational Infrastructure (NCI) at the Australian National University (ANU) is a partnership between CSIRO, ANU, Bureau of Meteorology (BoM) and Geoscience Australia. Recent investments in a 1.2 PFlop Supercomputer (Raijin), ~ 20 PB data storage using Lustre filesystems and a 3000 core high performance cloud have created a hybrid platform for higher performance computing and data-intensive science to enable large scale earth and climate systems modelling and analysis. There are > 3000 users actively logging in and > 600 projects on the NCI system. Efficiently scaling and adapting data and software systems to petascale infrastructures requires the collaborative development of an architecture that is designed, programmed and operated to enable users to interactively invoke different forms of in-situ computation over complex and large scale data collections. NCI makes available major and long tail data collections from both the government and research sectors based on six themes: 1) weather, climate and earth system science model simulations, 2) marine and earth observations, 3) geosciences, 4) terrestrial ecosystems, 5) water and hydrology and 6) astronomy, bio and social. Collectively they span the lithosphere, crust, biosphere, hydrosphere, troposphere, and stratosphere. Collections are the operational form for data management and access. Similar data types from individual custodians are managed cohesively. Use of international standards for discovery and interoperability allow complex interactions within and between the collections. This design facilitates a transdisciplinary approach to research and enables a shift from small scale, 'stove-piped' science efforts to large scale, collaborative systems science. This new and complex infrastructure requires a move to shared, globally trusted software frameworks that can be maintained and updated. Workflow engines become essential and need to integrate provenance, versioning, traceability, repeatability

  20. The Virtual Robotics Laboratory; TOPICAL

    The growth of the Internet has provided a unique opportunity to expand research collaborations between industry, universities, and the national laboratories. The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations

  8. Topical calcineurin inhibitors in systemic lupus erythematosus

    Christos E Lampropoulos

    2010-04-01

    Full Text Available Christos E Lampropoulos, David P D’CruzLupus Research Unit, Rayne Institute, St. Thomas’ Hospital, London, UKAbstract: Cutaneous lupus erythematosus (CLE encompasses a variety of lesions that may be refractory to systemic or topical agents. Discoid lupus erythematosus (DLE and subacute cutaneous lupus erythematosus (SCLE are the most common lesions in clinical practice. The topical calcineurin inhibitors, tacrolimus and pimecrolimus, have been used to treat resistant cutaneous lupus since 2002 and inhibit the proliferation and activation of T-cells and suppress immune-mediated cutaneous inflammation. This article reviews the mechanism of action, efficacy, adverse effects, and the recent concern about their possible carcinogenic effect. Although the total number of patients is small and there is only one relevant randomized controlled study, the data are encouraging. Many patients, previously resistant to systemic agents or topical steroids, improved after four weeks of treatment. DLE and SCLE lesions were less responsive, reflecting the chronicity of the lesions, although more than 50% of patients still showed improvement. Topical calcineurin inhibitors may be a safe and effective alternative to topical steroids for CLE although the only approved indication is for atopic dermatitis.Keywords: tacrolimus, pimecrolimus, cutaneous lupus erythematosus, topical calcineurin inhibitors

  9. Tracking Multiple Topics for Finding Interesting Articles

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

    2007-02-15

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

  10. Current topics in radiation measurements

    Current research topics in radiation measurements will be shown in this presentation. Applications of radiation measurements have grown with the development of radiation sources and new measurement techniques. Recent new developments in this field are briefly introduced. Optical techniques such as lasers and fiber optics, which are widely used in an optical communication field, are successfully applied to radiation measurements. Micro-fabrication techniques and the photolithography technique are indispensable for semiconductor or even gas detectors. Complicated analog signal processing is being simplified by the use of fast computation techniques available in digital chips. Cryogenic X-ray detectors are making a great progress in the energy resolution. Some of the current research topics found in the recent journals and international symposiums are as follows: the development of room temperature semiconductor radiation detectors like CdZnTe and SiC, new signal processing methods such as coplanar grid unipolar charge sensing, medical γ-ray imaging, the development of cryogenic X-ray detectors such as STJs (Superconducting Tunnel Junction) and TES (Transition Edge Sensor) microcalorimeters, micromachined gas proportional counters like MSGC/MGC/GEM, new detection system which requires both the energy and spatial resolutions, the search of longer wavelength scintillators, development of new fast scintillators such as LSO/YAP/LuAP, new digital waveform processing based on fast digitizing technique, etc. Current developments are especially focused on the increase of the information derived from the detector and the improvement in the resolution. One of the other directions of the development is toward the microscopic visualization of the radiation. Such an approach must solve many technological difficulties both in fabrication of the detectors and even in the detection scheme, however, we might proceed to open a new phase of radiation measurements soon.

  11. Adaptive ethnography

    Berth, Mette

    2005-01-01

    This paper focuses on the use of an adaptive ethnography when studying such phenomena as young people's use of mobile media in a learning perspective. Mobile media such as PDAs and mobile phones have a number of affordances which make them potential tools for learning. However, before we begin to...... design and develop educational materials for mobile media platforms we must first understand everyday use and behaviour with a medium such as a mobile phone. The paper outlines the research design for a PhD project on mobile learning which focuses on mobile phones as a way to bridge the gap between...... formal and informal learning contexts. The paper also proposes several adaptive methodological techniques for studying young people's interaction with mobiles....

  18. Adaptive Capacity and Traps

    William A. Brock

    2008-12-01

    Full Text Available Adaptive capacity is the ability of a living system, such as a social–ecological system, to adjust responses to changing internal demands and external drivers. Although adaptive capacity is a frequent topic of study in the resilience literature, there are few formal models. This paper introduces such a model and uses it to explore adaptive capacity by contrast with the opposite condition, or traps. In a social–ecological rigidity trap, strong self-reinforcing controls prevent the flexibility needed for adaptation. In the model, too much control erodes adaptive capacity and thereby increases the risk of catastrophic breakdown. In a social–ecological poverty trap, loose connections prevent the mobilization of ideas and resources to solve problems. In the model, too little control impedes the focus needed for adaptation. Fluctuations of internal demand or external shocks generate pulses of adaptive capacity, which may gain traction and pull the system out of the poverty trap. The model suggests some general properties of traps in social–ecological systems. It is general and flexible, so it can be used as a building block in more specific and detailed models of adaptive capacity for a particular region.

  19. Topics in statistical mechanics

    Elser, V.

    1984-05-01

    This thesis deals with four independent topics in statistical mechanics: (1) the dimer problem is solved exactly for a hexagonal lattice with general boundary using a known generating function from the theory of partitions. It is shown that the leading term in the entropy depends on the shape of the boundary; (2) continuum models of percolation and self-avoiding walks are introduced with the property that their series expansions are sums over linear graphs with intrinsic combinatorial weights and explicit dimension dependence; (3) a constrained SOS model is used to describe the edge of a simple cubic crystal. Low and high temperature results are derived as well as the detailed behavior near the crystal facet; (4) the microscopic model of the lambda-transition involving atomic permutation cycles is reexamined. In particular, a new derivation of the two-component field theory model of the critical behavior is presented. Results for a lattice model originally proposed by Kikuchi are extended with a high temperature series expansion and Monte Carlo simulation. 30 references.

  1. Superconcentration and related topics

    Chatterjee, Sourav

    2014-01-01

    A certain curious feature of random objects, introduced by the author as “super concentration,” and two related topics, “chaos” and “multiple valleys,” are highlighted in this book. Although super concentration has established itself as a recognized feature in a number of areas of probability theory in the last twenty years (under a variety of names), the author was the first to discover and explore its connections with chaos and multiple valleys. He achieves a substantial degree of simplification and clarity in the presentation of these findings by using the spectral approach. Understanding the fluctuations of random objects is one of the major goals of probability theory and a whole subfield of probability and analysis, called concentration of measure, is devoted to understanding these fluctuations. This subfield offers a range of tools for computing upper bounds on the orders of fluctuations of very complicated random variables. Usually, concentration of measure is useful when more direct prob...

  2. Advanced verification topics

    Bhattacharya, Bishnupriya; Hall, Gary; Heaton, Nick; Kashai, Yaron; Khan Neyaz; Kirshenbaum, Zeev; Shneydor, Efrat

    2011-01-01

    The Accellera Universal Verification Methodology (UVM) standard is architected to scale, but verification is growing and in more than just the digital design dimension. It is growing in the SoC dimension to include low-power and mixed-signal and the system integration dimension to include multi-language support and acceleration. These items and others all contribute to the quality of the SOC so the Metric-Driven Verification (MDV) methodology is needed to unify it all into a coherent verification plan. This book is for verification engineers and managers familiar with the UVM and the benefits it brings to digital verification but who also need to tackle specialized tasks. It is also written for the SoC project manager that is tasked with building an efficient worldwide team. While the task continues to become more complex, Advanced Verification Topics describes methodologies outside of the Accellera UVM standard, but that build on it, to provide a way for SoC teams to stay productive and profitable.

  9. Final Report - Regulatory Considerations for Adaptive Systems

    Wilkinson, Chris; Lynch, Jonathan; Bharadwaj, Raj

    2013-01-01

    This report documents the findings of a preliminary research study into new approaches to the software design assurance of adaptive systems. We suggest a methodology to overcome the software validation and verification difficulties posed by the underlying assumption of non-adaptive software in the requirementsbased- testing verification methods in RTCA/DO-178B and C. An analysis of the relevant RTCA/DO-178B and C objectives is presented showing the reasons for the difficulties that arise in showing satisfaction of the objectives and suggested additional means by which they could be satisfied. We suggest that the software design assurance problem for adaptive systems is principally one of developing correct and complete high level requirements and system level constraints that define the necessary system functional and safety properties to assure the safe use of adaptive systems. We show how analytical techniques such as model based design, mathematical modeling and formal or formal-like methods can be used to both validate the high level functional and safety requirements, establish necessary constraints and provide the verification evidence for the satisfaction of requirements and constraints that supplements conventional testing. Finally the report identifies the follow-on research topics needed to implement this methodology.

  10. Getting Started with Topic Modeling and MALLET

    Shawn Graham

    2016-05-01

    Full Text Available In this lesson you will first learn what topic modeling is and why you might want to employ it in your research. You will then learn how to install and work with the MALLET natural language processing toolkit to do so. MALLET involves modifying an environment variable (essentially, setting up a short-cut so that your computer always knows where to find the MALLET program and working with the command line (ie, by typing in commands manually, rather than clicking on icons or menus. We will run the topic modeller on some example files, and look at the kinds of outputs that MALLET installed. This will give us a good idea of how it can be used on a corpus of texts to identify topics found in the documents without reading them individually.

  17. Topics in probability

    Prabhu, Narahari

    2011-01-01

    Recent research in probability has been concerned with applications such as data mining and finance models. Some aspects of the foundations of probability theory have receded into the background. Yet, these aspects are very important and have to be brought back into prominence.

  18. Hot topic [editorial

    simulations 'would be seriously in error'. One may ask if this magazine should give space to Lindzen or those involved in geoengineering to air their views. Given the uncertainties still present within climate models and the potential costs of dealing with global warming, it would be wrong for Physics World to ignore those outside the mainstream. After all, as Richard Feynman once wrote: 'There is no harm in doubt and scepticism, for it is through these that new discoveries are made'. Physicists should never take anything at face value, not least a topic as important as climate change. (U.K.)

  19. Learning to Adapt. Organisational Adaptation to Climate Change Impacts

    Analysis of human adaptation to climate change should be based on realistic models of adaptive behaviour at the level of organisations and individuals. The paper sets out a framework for analysing adaptation to the direct and indirect impacts of climate change in business organisations with new evidence presented from empirical research into adaptation in nine case-study companies. It argues that adaptation to climate change has many similarities with processes of organisational learning. The paper suggests that business organisations face a number of obstacles in learning how to adapt to climate change impacts, especially in relation to the weakness and ambiguity of signals about climate change and the uncertainty about benefits flowing from adaptation measures. Organisations rarely adapt 'autonomously', since their adaptive behaviour is influenced by policy and market conditions, and draws on resources external to the organisation. The paper identifies four adaptation strategies that pattern organisational adaptive behaviour

  4. Research and Application Based on Adaptive Boosting Strategy and Modified CGFPA Algorithm: A Case Study for Wind Speed Forecasting

    Jiani Heng

    2016-03-01

    Full Text Available Wind energy is increasingly considered one of the most promising sustainable energy sources for its characteristics of cleanliness without any pollution. Wind speed forecasting is a vital problem in wind power industry. However, individual forecasting models ignore the significance of data preprocessing and model parameter optimization, which may lead to poor forecasting performance. In this paper, a novel hybrid [k, Bt] -ABBP (back propagation based on adaptive strategy with parameters k and Bt model was developed based on an adaptive boosting (AB strategy that integrates several BP (back propagation neural networks for wind speed forecasting. The fast ensemble empirical mode decomposition technique is initially conducted in the preprocessing stage to reconstruct data, while a novel modified FPA (flower pollination algorithm incorporating a conjugate gradient (CG is proposed for searching for the optimal parameters of the [k, Bt] -ABBP mode. The case studies of five wind power stations in Penglai, China are used as illustrative examples for evaluating the effectiveness and efficiency of the developed hybrid forecast strategy. Numerical results show that the developed hybrid model is simple and can satisfactorily approximate the actual wind speed series. Therefore, the developed hybrid model can be an effective tool in mining and analysis for wind power plants.

    of this study was to analyze the spatial, temporal, institutional and topical distribution of Brazilian research on accelerated soil erosion based on the organization of articles according to thematic lines and to discuss the depth of the approach to the fundamental issues of erosion in order to establish a bibliometric perspective. For this purpose, 225 articles of Brazilian institutions focused on soil erosion were scanned, registered in a database and classified into five thematic lines. Besides, multi-temporal maps were drawn using GIS tools. Brazilian research on erosion is recent and is characterized by: (a concentration in few institutions in the southern and southeastern Brazil, (b focused on two issues, related to the Universal Soil Loss Equation and comparisons of agricultural managements as related to soil loss, with a considerable influence of the consolidation level of the research centers, which have developed research on accelerated soil erosion along these two lines.

  8. Advancements in Topical Antifungal Vehicles.

    Kircik, Leon H

    2016-02-01

    The primary treatment for superficial fungal infections is antifungal topical formulations, and allylamines and azoles represent the two major classes of topical formulations that are used to treat these infections. The stratum corneum (SC) is composed of keratinocytes that are surrounded by a matrix of lipids. The efficacy of topically applied formulations depends on their ability to penetrate this lipid matrix, and the vehicle plays an integral role in the penetration of active molecule into skin. There are several challenges to formulating topical drugs, which include the biotransformation of the active molecules as they pass through the SC and the physical changes that occur to the vehicle itself when it is applied to the skin. This article will review current and emerging topical antifungal vehicles. PMID:26885798

  15. [Current topics in pediatric nutrition].

    Morali, A; Vidailhet, M

    2002-07-01

    As main current topics in pediatric nutrition we have considered the results of the continuing research on the long term consequences of fetal malnutrition and intra-uterine growth retardation with the concept of metabolic imprinting leading to chronic disease in adulthood, the progresses of knowledge in the fields of iron metabolism and regulatory mechanisms of satiety, hunger and energetic balance, a better determination of recommended docosahexanoic and arachidonic acids intake in the first months of life for premature and term infants, and the studies on probiotics and prebiotics utilization for preventive and curative purposes. The concerns about vitamin D insufficiency in France have markedly decreased with the generalization ten years ago of cholecalciferol supplementation of infant formula, and more recently the authorization of dairy products supplementation. On the contrary the problem of iron deficiency in young children remains, as well as two major nutritional concerns: the very low percentage of breast-fed infants and the dramatic increase of childhood obesity which affects presently 14% of 10 year old children versus 5% in 1980.

  17. Simulations suggest that social and natural sciences differ in their research strategies adapted to work for different knowledge landscapes

    Jaffe, Klaus

    2014-01-01

    Do different field of knowledge require different research strategies? A numerical model exploring different virtual knowledge landscapes, revealed different optimal search strategies. Trend following is maximized when the popularity of new discoveries determine the number of individuals researching it. This strategy works best when many researchers explore few large areas of knowledge. In contrast, individuals or small groups of researchers are better in discovering small bits of information in dispersed knowledge landscapes. The best technique for all situations simulated, is to adjust the number of researchers needed to explore a knowledge cluster according to the opportunities and the level of crowding in that cluster. Bibliometric data of scientific publications showed a continuous bipolar distribution of these strategies, ranging from natural sciences, with highly cited publications in journals containing a large number of articles, to the social sciences, with rarely cited publications in journals cont...

    CERN Bulletin

    2012-01-01

    The first annual ARDENT workshop took place in Vienna from 20 to 23 November. The workshop gathered together the Early-Stage Researchers (ESR) and their supervisors, plus other people involved from all the participating institutions.   “The meeting, which was organised with the local support of the Austrian Institute of Technology, was a nice opportunity for the ESRs to get together, meet each other, and present their research plans and some preliminary results of their work,” says Marco Silari, a member of CERN Radiation Protection Group and the scientist in charge of the programme. Two full days were devoted to a training course on radiation dosimetry, delivered by renowned experts. The workshop closed with a half-day visit to the MedAustron facility in Wiener Neustadt.

  19. Research on operation and maintenance support system adaptive to human recognition and understanding in human-centered plant

    As a human-centered plant, advanced nuclear power plant needs appropriate role sharing between human and mobile intelligent agents. Human-machine cooperation for plant operation and maintenance activities is also required with an advanced interface. Plant's maintenance is programmed using mobile robots working under the radiation environments instead of human beings. Operation and maintenance support system adaptive to human recognition and understanding should be developed to establish adequate human and machine interface so as to induce human capabilities to the full and enable human to take responsibility for plan's operation. Plant's operation and maintenance can be cooperative activities between human and intelligent automonous agents having surveillance and control functions. Infrastructure of multi-agent simulation system for the support system has been investigated and developed based on work plans derived from the scheduler. (T. Tanaka)

  20. Research on application of active disturbance rejection control based on adaptive GA in water level control of steam generator

    The steam generator of nuclear power plant is a nonlinear, time-varying system. Application of the active disturbance rejection control method in the water level control of steam generator can solve the contradiction between speed and overshoot in the conventional PID control system, and it also can compensate the internal and external disturbances of the object model dynamically. However, ADRC parameters are numerous and without uniform adjustment specification, and are very difficult to be tuned. In order to overcome the difficulties in the parameter tuning of the ADRC, the adaptive genetic algorithm is used to tune ADRC parameters. The simulation results show that its robustness and its control quality are better than those of the traditional cascade PID control. (authors)

    2014-01-01

    Full Text Available U-model can approximate a large class of smooth nonlinear time-varying delay system to any accuracy by using time-varying delay parameters polynomial. This paper proposes a new approach, namely, U-model approach, to solving the problems of analysis and synthesis for nonlinear systems. Based on the idea of discrete-time U-model with time-varying delay, the identification algorithm of adaptive neural network is given for the nonlinear model. Then, the controller is designed by using the Newton-Raphson formula and the stability analysis is given for the closed-loop nonlinear systems. Finally, illustrative examples are given to show the validity and applicability of the obtained results.

    Authentic research experiences are valuable components of effective undergraduate education. Research experiences during the first years of college are especially critical to increase persistence in science, technology, engineering, and mathematics fields. The Science Education Alliance Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) model provides a high-impact research experience to first-year students but is usually available to a limited number of students, and its implementation is costly in faculty time and laboratory space. To offer a research experience to all students taking introductory biology at Gonzaga University (n = 350/yr), we modified the traditional two-semester SEA-PHAGES course by streamlining the first-semester Phage Discovery lab and integrating the second SEA-PHAGES semester into other courses in the biology curriculum. Because most students in the introductory course are not biology majors, the Phage Discovery semester may be their only encounter with research. To discover whether students benefit from the first semester alone, we assessed the effects of the one-semester Phage Discovery course on students' understanding of course content. Specifically, students showed improvement in knowledge of bacteriophages, lab math skills, and understanding experimental design and interpretation. They also reported learning gains and benefits comparable with other course-based research experiences. Responses to open-ended questions suggest that students experienced this course as a true undergraduate research experience. PMID:27146160

  3. [Research on Adaptive Balance Reaction for Gait Slippery Instability Events on Level Walk Based on Plantar Pressure and Gait Parameter Analysis].

    Li, Yang; Zhang, Junxia; Si, Ying

    2015-12-01

    Nowadays, for gait instability phenomenon, many researches have been carried out at home and abroad. However, the relationship between plantar pressure and gait parameters in the process of balance adjustment is still unclear. This study describes the human body adaptive balance reaction during slip events on slippery level walk by plantar pressure and gait analysis. Ten healthy male subjects walked on a level path wearing shoes with two contrastive contaminants (dry, oil). The study collected and analyzed the change rule of spatiotemporal parameters, plantar pressure parameters, vertical ground reaction force (VGRF), etc. The results showed that the human body adaptive balance reaction during slip events on slippery level walk mainly included lighter touch at the heel strikes, tighter grip at the toe offs, a lower velocity, a shorter stride length and longer support time. These changes are used to maintain or recover body balance. These results would be able to explore new ideas and provide reference value for slip injury prevention, walking rehabilitation training design, research and development of walking assistive equipments, etc. PMID:27079090

  7. A prerecognition model for hot topic discovery based on microblogging data.

    Zhu, Tongyu; Yu, Jianjun

    2014-01-01

    The microblogging is prevailing since its easy and anonymous information sharing at Internet, which also brings the issue of dispersing negative topics, or even rumors. Many researchers have focused on how to find and trace emerging topics for analysis. When adopting topic detection and tracking techniques to find hot topics with streamed microblogging data, it will meet obstacles like streamed microblogging data clustering, topic hotness definition, and emerging hot topic discovery. This paper schemes a novel prerecognition model for hot topic discovery. In this model, the concepts of the topic life cycle, the hot velocity, and the hot acceleration are promoted to calculate the change of topic hotness, which aims to discover those emerging hot topics before they boost and break out. Our experiments show that this new model would help to discover potential hot topics efficiently and achieve considerable performance. PMID:25254235

  12. An external portable device for adaptive deep brain stimulation (aDBS) clinical research in advanced Parkinson's Disease.

    Arlotti, Mattia; Rossi, Lorenzo; Rosa, Manuela; Marceglia, Sara; Priori, Alberto

    2016-05-01

    Compared to conventional deep brain stimulation (DBS) for patients with Parkinson's Disease (PD), the newer approach of adaptive DBS (aDBS), regulating stimulation on the basis of the patient's clinical state, promises to achieve better clinical outcomes, avoid adverse-effects and save time for tuning parameters. A remaining challenge before aDBS comes into practical use is to prove its feasibility and its effectiveness in larger groups of patients and in more ecological conditions. We developed an external portable aDBS system prototype designed for clinical testing in freely-moving PD patients with externalized DBS electrodes. From a single-channel bipolar artifact-free recording, it analyses local field potentials (LFPs), during ongoing DBS for tuning stimulation parameters, independent from the specific feedback algorithm implemented. We validated the aDBS system in vitro, by testing both its sensing and closed-loop stimulation capabilities, and then tested it in vivo, focusing on the sensing capabilities. By applying the aDBS system prototype in a patient with PD, we provided evidence that it can track levodopa and DBS-induced LFP spectral power changes among different patient's clinical states. Our system, intended for testing LFP-based feedback strategies for aDBS, should help understanding how and whether aDBS therapy works in PD and indicating future technical and clinical advances.

  19. Genetic adaptive system for image understanding and learning research. Phase 1. Final technical report, 1 February-1 August 1989

    Douthat, D.Z.; Ross, K.W.

    1989-08-01

    This report documents the efforts and results of initial phase research on machine learning directed at application for real-time machine vision and automatic target recognition. The particular paradigm pursued is based on genetic algorithms and classifiers modeled on the summation of Mendelian genetic recombination, Darwinian selection, and ecological notions of competition. This machine-learning approach is strongly supported by sound statistical theory. A second thread of research was the development of massively parallel computing hardware based on the Geometric/Arithmetic Parallel Processor (GAPP). This machine has a large number of processors, each one bit wide with a full Arithmetic/Logic Unit (full adder) and with local memory per processor. The basic research hypothesis of the subject effort has been that GAPP contained sufficient hardware capability to provide a substrate for a Classifier and Genetic Algorithm system. The goal has been demonstrated by constructing and running the necessary software on the GAPP, its controller and its host. The resulting fusion of software and hardware is called a Genetic Algorithm/Classifier Engine (GACE) in the same sense as a LISP engine or a data base engine. The resulting quantum jump in performance should open doors both to application and to more interesting and relevant research.

  1. Topics on electricity trade

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective. Together with national liberalisation, the opening of the cross border trade between the countries is also urged. The first paper in this thesis describes those different liberalisation processes within northern Europe and discusses problems that may arise in a transition period for integrating the countries into a common electricity market with efficient cross-border competition. Before the liberalisation process started, the electricity generation was determined by a central load dispatch at known prices. The introduction of competition has necessitated the creation of new competitive markets, power exchanges and financial markets where generation and prices are determined by demand and supply on the markets. One implication of this is that investments in new plants shall be made under levels of uncertainty about future prices. The second paper in this thesis analyses the importance of introducing uncertainty in energy-economic modelling of the electricity supply sector. Another implication, which arises on introducing a new market structure and power exchanges, is that the design of the power exchanges influences the price setting on the markets. The third paper of this thesis analyses the price setting on the regulating power market on the Nordic power exchange Nord Pool. More precisely, the paper reveals the pattern of the prices on the regulating power market by analysing the cost of

  3. Adapt or perish? Assessing the recent shift in the European research funding arena from 'ELSA' to 'RRI'.

    Zwart, Hub; Landeweerd, Laurens; van Rooij, Arjan

    2014-12-01

    Two decades ago, in 1994, in the context of the 4(th) EU Framework Programme, ELSA was introduced as a label for developing and funding research into the ethical, legal and social aspects of emerging sciences and technologies. Currently, particularly in the context of EU funding initiatives such as Horizon2020, a new label has been forged, namely Responsible Research and Innovation (RRI). What is implied in this metonymy, this semantic shift? What is so new about RRI in comparison to ELSA? First of all, for both labels, the signifier (S) was introduced in a top-down manner, well before the concept that was signified by it (s) had acquired a clear and stable profile. In other words, the signifier preceded (and helped or helps to shape) the research strategies actually covered by these labels (the precedence of the signifier over the signified: S/s). Moreover, the newness of RRI does not reside in its interactive and anticipatory orientation, as is suggested by authors who introduced the term, but rather in its emphases on social-economic impacts (valorisation, employment and competitiveness).

    Full Text Available Jonisha Shepherd,1 Arash Taheri,1 Steven R Feldman1–31Center for Dermatology Research, Department of Dermatology, 2Department of Pathology, 3Department of Public Health Sciences, Wake Forest School of Medicine, Winston-Salem, NC, USABackground: Topical treatments are usually effective in mild psoriasis. However, the complexity of their use may result in low patient adherence with treatment. Combination of a vitamin D analog and a corticosteroid into a two-compound topical formulation has increased efficacy compared with either drug administered alone. Once-daily application of such a product would likely improve adherence. The purpose of this study was to determine whether twice-daily application of a calcipotriene + betamethasone topical formulation can provide improved clinical outcomes compared with once-daily treatment with the same product.Methods: A review of the literature was performed seeking clinical trials comparing once-daily versus twice-daily application of calcipotriene + betamethasone topical formulations for the treatment of psoriasis.Results: We found only one relevant clinical trial. This study showed similar efficacy and safety with once-daily versus twice-daily application of a topical calcipotriene + betamethasone formulation in the treatment of psoriasis vulgaris.Conclusion: Once-daily application of a topical calcipotriene + betamethasone formulation may offer increased patient convenience and potentially increased patient adherence with long-term treatment, compared with twice-daily use, without reducing the efficacy. In order to enhance adherence, patient preference regarding frequency of application of topical treatments should be considered when prescribing medications.Keywords: calcipotriene, betamethasone, once daily, twice daily, psoriasis, combination product

    Owing to its ability to regenerate epidermal cells Dexpanthenol (D-panthenol; chemically known as (+)-2,4-dihydroxy-N-(3-hydroxypropyl)-3,3-dimethylbutyramide) has found use for the treatment of patholytic ileus and postoperative distention. The purpose of research was to develop a gel containing dexpanthenol by monitoring the effect of various concentrations of a gelating agent on the activity of the ciliary apparatus. A system containing 2.5% of hydroxyethylcellulose was optimal for the preparation of the gel. Together with a formulation containing 5% of dexpanthenol, drops with equal concentration of the active compound were tested for comparison. Physical characteristics, such as osmotic pressure, acidity, density and viscosity of the preparation were determined as well as its microbiological sterility. The anti-inflammatory activity of the gel was determined following its topical application. Epidermal tests showed its good tolerance after topical application to the shaved skin of guinea pigs.

    Adaptive Lighting Adaptive lighting is based on a partial automation of the possibilities to adjust the colour tone and brightness levels of light in order to adapt to people’s needs and desires. IT support is key to the technical developments that afford adaptive control systems. The possibilities...... offered by adaptive lighting control are created by the ways that the system components, the network and data flow can be coordinated through software so that the dynamic variations are controlled in ways that meaningfully adapt according to people’s situations and design intentions. This book discusses...... distributed differently into an architectural body. We also examine what might occur when light is dynamic and able to change colour, intensity and direction, and when it is adaptive and can be brought into interaction with its surroundings. In short, what happens to an architectural space when artificial...

    Full Text Available Introduction Understanding of fluid shifts and recognition of the importance of early and appropriate fluid replacement therapy have significantly reduced mortality in the early post burn period. After the bum patient successfully passes the resuscitation period, the burn wound represents the greatest threat to survival. History Since the dawn of civilization, man has been trying to find an agent which would help burn wounds heal, and at the same time, not harm general condition of the injured. It was not until the XX century, after the discovery of antibiotics, when this condition was fulfilled. In 1968, combining silver and sulfadiazine, fox made silver-sulfadiazine, which is a 1% hydro-soluble cream and a superior agent in topical treatment of burns today. Current topical agents None of the topical antimicrobial agents available today, alone or combined, have the characteristics of ideal prophylactic agents, but they eliminate colonization of burn wound, and invasive infections are infrequent. With an excellent spectrum of activity, low toxicity, and ease of application with minimal pain, silver-sulfadiazine is still the most frequently used topical agent. Conclusion The incidence of invasive infections and overall mortality have been significantly reduced after introduction of topical burn wound antimicrobial agents into practice. In most burn patients the drug of choice for prophylaxis is silver sulfadiazine. Other agents may be useful in certain clinical situations.

    2014-01-01

    Full Text Available Corticosteroids, one of the most widely prescribed topical drugs, have been used for about six decades till date. However, rampant misuse and abuse down the years has given the drug a bad name. Topical steroid abuse may lead to two major problems which lie at the opposing ends of the psychosomatic spectrum. Topical steroid addiction, a phenomenon that came to be recognized about a decade after the introduction of the molecule is manifested as psychological distress and rebound phenomenon on stoppage of the drug. The rebound phenomenon, which can affect various parts of the body particularly the face and the genitalia has been reported by various names in the literature. TC phobia which lies at the opposite end of the psychiatric spectrum of steroid abuse has been reported particularly among parents of atopic children. Management of both conditions is difficult and frustrating. Psychological counseling and support can be of immense help in both the conditions.

  16. Knowledge exchange for climate adaptation planning in western North America

    Garfin, Gregg; Orr, Barron

    2015-04-01

    In western North America, the combination of sustained drought, rapid ecosystem changes, and land use changes associated with urban population growth has motivated concern among ecosystem managers about the implications of future climate changes for the landscapes which they manage. Through literature review, surveys, and workshop discussions, we assess the process of moving from concern, to planning, to action, with an emphasis on questions, such as: What are the roles of boundary organizations in facilitating knowledge exchange? Which practices lead to effective interactions between scientists, decision-makers, and knowledge brokers? While there is no "one size fits all" science communication method, the co-production of science and policy by research scientists, science translators, and decision-makers, as co-equals, is a resource intensive, but effective practice for moving adaptation planning forward. Constructive approaches make use of alliances with early adopters and opinion leaders, and make strong communication links between predictions, impacts and solutions. Resource managers need information on the basics of regional climate variability and global climate change, region-specific projections of climate changes and impacts, frank discussion of uncertainties, and opportunities for candid exploration of these topics with peers and subject experts. Research scientists play critical roles in adaptation planning discussions, because they assist resource managers in clarifying the cascade of interactions leading to potential impacts and, importantly, because decision-makers want to hear the information straight from the scientists conducting the research, which bolsters credibility. We find that uncertainty, formerly a topic to avoided, forms the foundation for constructive progress in adaptation planning. Candid exploration of the array of uncertainties, including those due to modeling, institutional, policy and economic factors, with practitioners, science

  18. Web mining for topics defined by complex and precise predicates

    Lee, Ching-Cheng; Sampathkumar, Sushma

    2004-04-01

    The enormous growth of the World Wide Web has made it important to perform resource discovery efficiently for any given topic. Several new techniques have been proposed in the recent years for this kind of topic specific web-mining, and among them a key new technique called focused crawling which is able to crawl topic-specific portions of the web without having to explore all pages. Most existing research on focused crawling considers a simple topic definition that typically consists of one or more keywords connected by an OR operator. However this kind of simple topic definition may result in too many irrelevant pages in which the same keyword appears in a wrong context. In this research we explore new strategies for crawling topic specific portions of the web using complex and precise predicates. A complex predicate will allow the user to precisely specify a topic using Boolean operators such as "AND", "OR" and "NOT". Our work will concentrate on defining a format to specify this kind of a complex topic definition and secondly on devising a crawl strategy to crawl the topic specific portions of the web defined by the complex predicate, efficiently and with minimal overhead. Our new crawl strategy will improve the performance of topic-specific web crawling by reducing the number of irrelevant pages crawled. In order to demonstrate the effectiveness of the above approach, we have built a complete focused crawler called "Eureka" with complex predicate support, and a search engine that indexes and supports end-user searches on the crawled pages.

    在风洞天平校准系统中,加载头的主要功能是保证力的三要素中“作用点”位置的准确。然而,由于加工制造误差和尺寸测量误差的存在,加载头施力点的实际位置总是会偏离其相应的理论正确位置,从而导致施力点位置坐标产生误差。这些误差会经由加载头传导到天平校准公式中,从而影响天平载荷测量的准确性。因此,有必要对加载头不确定度的评定方法进行研究。首先采用GUM(guide to the expression of uncertainty in the meas-urement,ISO/IEC GUIDE 98-3:2008)方法建立了加载头不确定度的评定方法和步骤,接着给出了加载头不确定度的表示方法及指标要求,最后以某加载头为例,给出了不确定度评定的详细过程及结果。结果表明,该型加载头各施力点位置坐标的扩展不确定度平均值为0.044mm;力矩力臂的相对扩展不确定度平均值为0.0072%。%In the wind tunnel balance calibration system,the main function of the load adapter is to ensure that the application point’s location coordinates are accurate.However,because of the manufacture error and dimension measurement error,the application points’real locations are drifted off from the relevant right locations in the theory,which brings errors to the applica-tion point’s location coordinates.These errors would be transferred to a balance calibration for-mula by a load adapter,which affects the accuracy of the loads measured by the balance.There-fore,it is necessary to research on the evaluation and expression of the uncertainty for a load a-dapter.Firstly,according to GUM (guide to the expression of uncertainty in the measurement, ISO/IEC GUIDE 98-3:2008),a method and steps for uncertainty assessment of a load adapter are founded.Then an expression and technical indices of the uncertainty for a load adapter are given.Finally,taking the type A load adapter belonging to the balance
