The likely requirement that books should be OA if submitted to the REF (Research Excellence Framework after next means that OA development must be based on an understanding of the importance of the monograph in the AHSS (arts, humanities and social sciences as well as the challenges involved in making the transition to online OA. The project focused on three issues and each is summarized in turn in the article: What is the place of the monograph and other long-form publications in AHSS disciplines that makes it so important? What is happening to the monograph and is there a crisis as some suggest? What are the issues involved in moving monographs into a digital and OA environment – not just the challenge of effective business models but also many other aspects of sustaining and enhancing the qualities of the monograph? These include third-party rights, technical challenges, licences and the need for international collaboration.

    BACKGROUND: Recently the International Agency for Research on Cancer (IARC) Programme for the Evaluation of Carcinogenic Risks to Humans has been criticized for several of its evaluations, and also the approach used to perform these evaluations. Some critics have claimed that IARC Working Groups...... carcinogens. We have examined here criticisms of the IARC classification process to determine the validity of these concerns. We review the history of IARC evaluations and describe how the IARC evaluations are performed. DISCUSSION: We conclude that these recent criticisms are unconvincing. The procedures....... This does not mean, however, that the current procedures are flawed. CONCLUSIONS: The IARC Monographs have made, and continue to make, major contributions to the scientific underpinning for societal actions to improve the public's health....

    Approximately 30% of patients with breast cancer will develop metastatic breast disease. Metastatic breast cancer is considered an incurable disease, with complete remission rarely achieved after treatment. The goal of treatment for metastatic breast cancer patients is to increase overall survival time and delay disease progression while ameliorating symptoms and improving or maintaining quality of life. Single-agent therapeutic regimens are appropriate for most metastatic breast cancer patients. Patients with the luminal A subtype of breast cancer, which is more indolent in nature and tends to be more sensitive to treatment in general, often respond well to single-agent therapy. Several chemotherapy regimens are recommended for the treatment of metastatic breast cancer. Compared with single-agent regimens, these combination regimens often produce a greater improvement in the rate of objective response as well as a prolongation of progression-free survival. There is little evidence, however, of improvement in overall survival. Combination chemotherapy regimens are often associated with a greater degree of toxicity depending on schedules and doses used. The use of bevacizumab in metastatic breast cancer is currently a topic of controversy. It is hoped that forthcoming trial data will enable the identification of a group of patients, based on tumor biology, who could benefit from bevacizumab-based therapy.

    Children require special considerations for drug prescribing. Drug information summarized in a formulary containing drug monographs is essential for safe and effective prescribing. Currently, little is known about the information needs of those who prescribe and administer medicines to children. Our primary objective was to identify a list of important and relevant items to be included in a pediatric drug monograph. Following the establishment of an expert steering committee and an environmental scan of adult and pediatric formulary monograph items, 46 participants from 25 countries were invited to complete a 2-round Delphi survey. Questions regarding source of prescribing information and importance of items were recorded. An international consensus meeting to vote on and finalize the items list with the steering committee followed. Pediatric formularies are most commonly the first resource consulted for information on medication used in children by 31 Delphi participants. After the Delphi rounds, 116 items were identified to be included in a comprehensive pediatric drug monograph, including general information, adverse drug reactions, dosages, precautions, drug-drug interactions, formulation, and drug properties. Health care providers identified 116 monograph items as important for prescribing medicines for children by an international consensus-based process. This information will assist in setting standards for the creation of new pediatric drug monographs for international application and for those involved in pediatric formulary development.

    Full Text Available Twitter, an online micro blogs, enables its users to write and read text-based posts known as “tweets”. It became one of the most commonly used social networks. However, an important problem arises is that the returned tweets, when searching for a topic phrase, are only sorted by recency not relevancy. This makes the user to manually read through the tweets in order to understand what are primarily saying about the particular topic. Some strategies were developed for summarizing English micro blogs but Arabic micro blogs summarization is still an active research area. This paper presents a machine learning based solution for summarizing Arabic micro blogging posts and more specifically Egyptian dialect summarization. The goal is to produce short summary for Arabic tweets related to a specific topic in less time and effort. The proposed strategy is evaluated and the results are compared with that obtained by the well-known multi-document summarization algorithms including; SumBasic, TF-IDF, PageRank, MEAD, and human summaries.

    1998-12-01

    We address the problem of key-frame summarization of vide in the absence of any a priori information about its content. This is a common problem that is encountered in home videos. We propose a hierarchical key-frame summarization algorithm where a coarse-to-fine key-frame summary is generated. A hierarchical key-frame summary facilitates multi-level browsing where the user can quickly discover the content of the video by accessing its coarsest but most compact summary and then view a desired segment of the video with increasingly more detail. At the finest level, the summary is generated on the basis of color features of video frames, using an extension of a recently proposed key-frame extraction algorithm. The finest level key-frames are recursively clustered using a novel pairwise K-means clustering approach with temporal consecutiveness constraint. We also address summarization of MPEG-2 compressed video without fully decoding the bitstream. We also propose efficient mechanisms that facilitate decoding the video when the hierarchical summary is utilized in browsing and playback of video segments starting at selected key-frames.

    Full Text Available Summarization is a process to select important information from a source text. Summarizing strategies are the core cognitive processes in summarization activity. Since summarization can be important as a tool to improve comprehension, it has attracted interest of teachers for teaching summary writing through direct instruction. To do this, they need to review and assess the students' summaries and these tasks are very time-consuming. Thus, a computer-assisted assessment can be used to help teachers to conduct this task more effectively.This paper aims to propose an algorithm based on the combination of semantic relations between words and their syntactic composition to identify summarizing strategies employed by students in summary writing. An innovative aspect of our algorithm lies in its ability to identify summarizing strategies at the syntactic and semantic levels. The efficiency of the algorithm is measured in terms of Precision, Recall and F-measure. We then implemented the algorithm for the automated summarization assessment system that can be used to identify the summarizing strategies used by students in summary writing.

  15. Video summarization using motion descriptors

    Science.gov (United States)

    Divakaran, Ajay; Peker, Kadir A.; Sun, Huifang

    2001-01-01

    We describe a technique for video summarization that uses motion descriptors computed in the compressed domain to speed up conventional color based video summarization technique. The basic hypothesis of the work is that the intensity of motion activity of a video segment is a direct indication of its 'summarizability.' We present experimental verification of this hypothesis. We are thus able to quickly identify easy to summarize segments of a video sequence since they have a low intensity of motion activity. Moreover, the compressed domain extraction of motion activity intensity is much simpler than the color-based calculations. We are able to easily summarize these segments by simply choosing a key-frame at random from each low- activity segment. We can then apply conventional color-based summarization techniques to the remaining segments. We are thus able to speed up color-based summarization techniques by reducing the number of segments on which computationally more expensive color-based computation is needed.

    Daumé, Hal

    2009-01-01

    We present BayeSum (for ``Bayesian summarization''), a model for sentence extraction in query-focused summarization. BayeSum leverages the common case in which multiple documents are relevant to a single query. Using these documents as reinforcement for query terms, BayeSum is not afflicted by the paucity of information in short queries. We show that approximate inference in BayeSum is possible on large data sets and results in a state-of-the-art summarization system. Furthermore, we show how BayeSum can be understood as a justified query expansion technique in the language modeling for IR framework.

    The ability to summarize and abstract information will be an essential part of intelligent behavior in consumer devices. Various summarization methods have been the topic of intensive research in the content-based video analysis community. Summarization in traditional information retrieval is a well understood problem. While there has been a lot of research in the multimedia community there is no agreed upon terminology and classification of the problems in this domain. Although the problem has been researched from different aspects there is usually no distinction between the various dimensions of summarization. The goal of the paper is to provide the basic definitions of widely used terms such as skimming, summarization, and highlighting. The different levels of summarization: local, global, and meta-level are made explicit. We distinguish among the dimensions of task, content, and method and provide an extensive classification model for the same. We map the existing summary extraction approaches in the literature into this model and we classify the aspects of proposed systems in the literature. In addition, we outline the evaluation methods and provide a brief survey. Finally we propose future research directions based on the white spots that we identified by analysis of existing systems in the literature.

    Full Text Available The paper attempts to reconsider some theoretical and methodological principles practiced by the Bucharest School of Sociology by invoking some concepts put forward by the so called Critical Ethnography. It considers three major ideas of the Monographic Sociology, that can be also found as theoretical assumptions of the postmodern critical ethnographic theory, in an interesting parallel that can be, thus, reconstructed and further suggested as useful paradigm within current approaches in social sciences and policies: interdisciplinarity, activism and criticism. The paper concludes on the contribution that the Monographic School may have to the current social theory, research and policy developed today in Romania.

    2015-01-01

    This monograph deals with all 95 names described in the Cucurbitaceae genus Coccinia and recognizes 25 species. Taxonomic novelties are Cocciniaadoensisvar.aurantiaca (C.Jeffrey) Holstein, stat. nov., Cocciniasessilifoliavar.variifolia (A.Meeuse) Holstein, stat. nov., and Cocciniaadoensisvar.jeffreyana Holstein, var. nov. For the 25 species 3157 collections were examined, of which 2024 were georeferenced to produce distribution maps. All species are distributed in sub-Saharan Africa with one species, Cocciniagrandis, extending from Senegal in West Africa east to Indonesia and being naturalized on Pacific Islands, in Australia, the Caribbean, and South America. Coccinia species are dioecious creepers or climbers with simple or bifid tendrils that occupy a range of habitats from arid scrubland, woodlands to lowland rainforest and mist forest. The corolla of Coccinia species is sympetalous, usually pale yellow to orange, and 1 to 4.5 cm long. Pollination is by bees foraging for pollen or nectar. After pollination, the developing ovary often exhibits longitudinal mottling, which usually disappears during maturation. All species produce berries with a pericarp in reddish colors (orange-red through to scarlet red), hence the generic name. The globose to cylindrical fruits contain numerous grayish-beige flat to lenticular seeds. Chromosome numbers are 2n = 20, 24, and 22 + XX/XY. Many Coccinia species are used for food, either as roasted tubers, greens as spinach, or the fruits as vegetables. Medicinal value is established in Cocciniagrandis, of which leaves and sap are used against diabetes.

    Bearing in mind the rising prevalence of chronic medical conditions, the chronic disease management is one of the key features required by medical information systems used in primary healthcare. Our research group paid a particular attention to this specific area by offering a set of custom data collection forms and reports in order to improve medical professionals' daily routine. The main idea was to provide an overview of history for chronic diseases, which, as it seems, had not been properly supported in previous administrative workflows. After five years of active use of medical information systems in more than 25 primary healthcare institutions, we were able to identify several scenarios that were often end-user-action dependent and could result in the data related to chronic diagnoses being loosely connected. An additional benefit would be a more effective identification of potentially new patients suffering from chronic diseases. For this particular reason, we introduced an extension of the existing data structures and a summarizing method along with a specific tool that should help in connecting all the data related to a patient and a diagnosis. The summarization method was based on the principle of connecting all of the records pertaining to a specific diagnosis for the selected patient, and it was envisaged to work in both automatic and on-demand mode. The expected results were a more effective identification of new potential patients and a completion of the existing histories of diseases associated with chronic diagnoses. The current system usage analysis shows that a small number of doctors used functionalities specially designed for chronic diseases affecting less than 6% of the total population (around 11,500 out of more than 200,000 patients). In initial tests, the on-demand data summarization mode was applied in general practice and 89 out of 155 users identified more than 3000 new patients with a chronic disease over a three-month test period

    Abt, Helmut A.

    2014-04-01

    I explored the use of astronomical monographs used for research. After scanning 135 monographs (excluding conference proceedings and textbooks) listed in 2000-2003 issues of Physics Today and counting citations of them in 2000-2013 in ADS (Astrophysics Data System), I found that 67% of the monographs received fewer than 2 citations per year. The average citation rate for the 135 monographs is statistically the same as for ApJ papers. In contrast, only 41% of the ApJ papers produce fewer than 2 citations per year. ADS also counts the number of times each book or paper is read on-line. The average in 14 years is 181 ± 27 times for the monographs and 633 ± 47 times for ApJ papers. The total numbers of citations in 14 years for the monographs ranged from 0 to 711. I explored reasons for this range and only learned that it did not depend on (1) the numbers of book reviews published or (2) the scientific stature of the authors. I am unable to predict whether a monograph will be successful or not. The decreasing of references to monographs seems to be due to (1) monographs becoming so expensive that individuals and libraries cannot afford many of them, (2) readers seeming to prefer concise reviews, such as online searches and the Annual Reviews, and (3) most of the monographs having not been available free online.

  11. Dynamic summarization of bibliographic-based data

    2011-02-01

    Full Text Available Abstract Background Traditional information retrieval techniques typically return excessive output when directed at large bibliographic databases. Natural Language Processing applications strive to extract salient content from the excessive data. Semantic MEDLINE, a National Library of Medicine (NLM natural language processing application, highlights relevant information in PubMed data. However, Semantic MEDLINE implements manually coded schemas, accommodating few information needs. Currently, there are only five such schemas, while many more would be needed to realistically accommodate all potential users. The aim of this project was to develop and evaluate a statistical algorithm that automatically identifies relevant bibliographic data; the new algorithm could be incorporated into a dynamic schema to accommodate various information needs in Semantic MEDLINE, and eliminate the need for multiple schemas. Methods We developed a flexible algorithm named Combo that combines three statistical metrics, the Kullback-Leibler Divergence (KLD, Riloff's RlogF metric (RlogF, and a new metric called PredScal, to automatically identify salient data in bibliographic text. We downloaded citations from a PubMed search query addressing the genetic etiology of bladder cancer. The citations were processed with SemRep, an NLM rule-based application that produces semantic predications. SemRep output was processed by Combo, in addition to the standard Semantic MEDLINE genetics schema and independently by the two individual KLD and RlogF metrics. We evaluated each summarization method using an existing reference standard within the task-based context of genetic database curation. Results Combo asserted 74 genetic entities implicated in bladder cancer development, whereas the traditional schema asserted 10 genetic entities; the KLD and RlogF metrics individually asserted 77 and 69 genetic entities, respectively. Combo achieved 61% recall and 81% precision, with an F

    2014-01-01

    Full Text Available The use of medicinal plants in Brazil is widespread and is supported by public policies; it has the objective of providing the population with safe and effective herbal medicines of adequate quality. An action in these policies is to develop medicinal plant monographs to gather published information and decide which medicinal plants should be financed by the Brazilian government and distributed by the public health system. Currently, the monographs published worldwide do not present unified information regarding medicinal plants, and generally, they do not cover enough requirements for herbal medicine registration. The aim of this study is to develop a monograph model with standardized information not only about botany, agronomy, quality control, safety, and efficacy but also about relating regulatory aspects that support herbal medicine regulation. The development of standardized monographs favors the fast authorization and distribution of herbal medicines in the public system. The model also points out the lacking studies that should be carried out to supplement the necessary regulatory information of medicinal plants.

    2012-05-01

    Full Text Available Abstract Background PubMed data potentially can provide decision support information, but PubMed was not exclusively designed to be a point-of-care tool. Natural language processing applications that summarize PubMed citations hold promise for extracting decision support information. The objective of this study was to evaluate the efficiency of a text summarization application called Semantic MEDLINE, enhanced with a novel dynamic summarization method, in identifying decision support data. Methods We downloaded PubMed citations addressing the prevention and drug treatment of four disease topics. We then processed the citations with Semantic MEDLINE, enhanced with the dynamic summarization method. We also processed the citations with a conventional summarization method, as well as with a baseline procedure. We evaluated the results using clinician-vetted reference standards built from recommendations in a commercial decision support product, DynaMed. Results For the drug treatment data, Semantic MEDLINE enhanced with dynamic summarization achieved average recall and precision scores of 0.848 and 0.377, while conventional summarization produced 0.583 average recall and 0.712 average precision, and the baseline method yielded average recall and precision values of 0.252 and 0.277. For the prevention data, Semantic MEDLINE enhanced with dynamic summarization achieved average recall and precision scores of 0.655 and 0.329. The baseline technique resulted in recall and precision scores of 0.269 and 0.247. No conventional Semantic MEDLINE method accommodating summarization for prevention exists. Conclusion Semantic MEDLINE with dynamic summarization outperformed conventional summarization in terms of recall, and outperformed the baseline method in both recall and precision. This new approach to text summarization demonstrates potential in identifying decision support data for multiple needs.

    2012-06-01

    Although reductions in lead (Pb) exposure for the U.S. population have resulted in lower blood Pb levels over time, epidemiological studies continue to provide evidence of health effects at lower and lower blood Pb levels. Low-level Pb was selected for evaluation by the National Toxicology Program (NTP) because of (1) the availability of a large number of epidemiological studies of Pb, (2) a nomination by the National Institute for Occupational Safety and Health for an assessment of Pb at lower levels of exposure, and (3) public concern for effects of Pb in children and adults. This evaluation summarizes the evidence in humans and presents conclusions on health effects in children and adults associated with low-level Pb exposure as indicated by less than 10 micrograms of Pb per deciliter of blood (Monograph on Health Effects of Low-Level Lead. The document and appendices are available at http://ntp.niehs.nih.gov/go/evals. This document provides background on Pb exposure and includes a review of the primary epidemiological literature for evidence that low-level Pb is associated with neurological, immunological, cardiovascular, renal, and/or reproductive and developmental effects. The NTP Monograph presents specific conclusions for each health effect area. Overall, the NTP concludes that there is sufficient evidence that blood Pb levels Monograph on November 17-18, 2011 (http://ntp.niehs.nih.gov/go/37090.

    Full Text Available Due to the explosive amounts of text data being created and organizations increased desire to leverage their data corpora, especially with the availability of Big Data platforms, there is not usually enough time to read and understand each document and make decisions based on document contents. Hence, there is a great demand for summarizing text documents to provide a representative substitute for the original documents. By improving summarizing techniques, precision of document retrieval through search queries against summarized documents is expected to improve in comparison to querying against the full spectrum of original documents. Several generic text summarization algorithms have been developed, each with its own advantages and disadvantages. For example, some algorithms are particularly good for summarizing short documents but not for long ones. Others perform well in identifying and summarizing single-topic documents but their precision degrades sharply with multi-topic documents. In this article we present a survey of the literature in text summarization. We also surveyed some of the most common evaluation methods for the quality of automated text summarization techniques. Last, we identified some of the challenging problems that are still open, in particular the need for a universal approach that yields good results for mixed types of documents.

    2016-01-01

    This paper presents a literature review in the field of summarizing software artifacts, focusing on bug reports, source code, mailing lists and developer discussions artifacts. From Jan. 2010 to Apr. 2016, numerous summarization techniques, approaches, and tools have been proposed to satisfy the ongoing demand of improving software performance and quality and facilitating developers in understanding the problems at hand. Since aforementioned artifacts contain both structured and unstructured data at the same time, researchers have applied different machine learning and data mining techniques to generate summaries. Therefore, this paper first intends to provide a general perspective on the state of the art, describing the type of artifacts, approaches for summarization, as well as the common portions of experimental procedures shared among these artifacts. Moreover, we discuss the applications of summarization, i.e., what tasks at hand have been achieved through summarization. Next, this paper presents tools that are generated for summarization tasks or employed during summarization tasks. In addition, we present different summarization evaluation methods employed in selected studies as well as other important factors that are used for the evaluation of generated summaries such as adequacy and quality. Moreover, we briefly present modern communication channels and complementarities with commonalities among different software artifacts. Finally, some thoughts about the challenges applicable to the existing studies in general as well as future research directions are also discussed. The survey of existing studies will allow future researchers to have a wide and useful background knowledge on the main and important aspects of this research field.

    2003-12-01

    This paper proposes a statistical approach to automatic speech summarization. In our method, a set of words maximizing a summarization score indicating the appropriateness of summarization is extracted from automatically transcribed speech and then concatenated to create a summary. The extraction process is performed using a dynamic programming (DP) technique based on a target compression ratio. In this paper, we demonstrate how an English news broadcast transcribed by a speech recognizer is automatically summarized. We adapted our method, which was originally proposed for Japanese, to English by modifying the model for estimating word concatenation probabilities based on a dependency structure in the original speech given by a stochastic dependency context free grammar (SDCFG). We also propose a method of summarizing multiple utterances using a two-level DP technique. The automatically summarized sentences are evaluated by summarization accuracy based on a comparison with a manual summary of speech that has been correctly transcribed by human subjects. Our experimental results indicate that the method we propose can effectively extract relatively important information and remove redundant and irrelevant information from English news broadcasts.

    Full Text Available This article evaluates the current state of academic book publishing based on the findings of the Hybrid Publishing Lab's business model research. With students relying more and more on Google and Wikipedia, the role of books within today's university studies is a difficult one. From the perspective of publishers, open access (OA embracing the digital is seen as one potential way to bridge this gap between online search engines and traditional monographs. To illustrate this further, the article delivers an overview of its findings, which highlight changes in academic publishing: publishers have switched their emphasis from delivering a product to creating a service, whereby the author rather than the reader becomes their most focused-on customer. Research frameworks, funding and conventions about academic careers, however, often still need to adjust to this new development. If these frameworks acknowledge and foster OA publishing, and new experiments with collaborative book productions flourish, the monograph will have a future.

    1997-01-01

    The practice of limiting the shaker force in vibration tests was investigated at the NASA Jet Propulsion Laboratory (JPL) in 1990 after the mechanical failure of an aerospace component during a vibration test. Now force limiting is used in almost every major vibration test at JPL and in many vibration tests at NASA Goddard Space Flight Center (GSFC) and at many aerospace contractors. The basic ideas behind force limiting have been in the literature for several decades, but the piezo-electric force transducers necessary to conveniently implement force limiting have been available only in the last decade. In 1993, funding was obtained from the NASA headquarters Office of Chief Engineer to develop and document the technology needed to establish force limited vibration testing as a standard approach available to all NASA centers and aerospace contractors. This monograph is the final report on that effort and discusses the history, theory, and applications of the method in some detail.

    Although the goal of traditional text summarization is to generate summaries with diverse information,most of those applications have no explicit definition of the information structure.Thus,it is difficult to generate truly structureaware summaries because the information structure to guide summarization is unclear.In this paper,we present a novel framework to generate guided summaries for product reviews.The guided summary has an explicitly defined structure which comes from the important aspects of products.The proposed framework attempts to maximize expected aspect satisfaction during summary generation.The importance of an aspect to a generated summary is modeled using Labeled Latent Dirichlet Allocation.Empirical experimental results on consumer reviews of cars show the effectiveness of our method.

  9. Summarizing Vocabularies in the Global Semantic Web

    2009-01-01

    In the Semantic Web, vocabularies are defined and shared among knowledge workers to describe linked data for scientific, industrial or daily life usage. With the rapid growth of online vocabularies, there is an emergent need for approaches helping users understand vocabularies quickly. In this paper, we study the summarization of vocabularies to help users understand vocabularies. Vocabulary summarization is based on the structural analysis and pragmatics statistics in the global Semantic Web. Local Bipartite Model and Expanded Bipartite Model of a vocabulary are proposed to characterize the structure in a vocabulary and links between vocabularies. A structural importance for each RDF sentence in the vocabulary is assessed using link analysis. Meanwhile, pragmatics importance of each RDF sentence is assessed using the statistics of instantiation of its terms in the Semantic Web. Summaries are produced by extracting important RDF sentences in vocabularies under a re-ranking strategy. Preliminary experiments show that it is feasible to help users understand a vocabulary through its summary.

    We present two new vortex-summarization techniques designed to portray vortex motion over an entire simulation and over an ensemble of simulations in a single image. Linear "vortex core timelines" with cone glyphs summarize flow over all time steps of a single simulation, with color varying to indicate time. Simplified "ribbon summarizations" with hue nominally encoding ensemble membership and saturation encoding time enable direct visual comparison of the distribution of vortices in time and space for a set of simulations.

    2014-06-01

    Full Text Available Now day’s internet has become part of our life, the WWW is most important service of internet because it allows presenting information such as document, imaging etc. The WWW grows rapidly and caters to a diversified levels and categories of users. For user specified results web search results are extracted. Millions of information pouring online, users has no time to surf the contents completely .Moreover the information available is repeated or duplicated in nature. This issue has created the necessity to restructure the search results that could yield results summarized. The proposed approach comprises of different feature extraction of web pages. Web page visual similarity assessment has been employed to address the problems in different fields including phishing, web archiving, web search engine etc. In this approach, initially by enters user query the number of search results get stored. The Earth Mover's Distance is used to assessment of web page visual similarity, in this technique take the web page as a low resolution image, create signature of that web page image with color and co-ordinate features .Calculate the distance between web pages by applying EMD method. Compute the Layout Similarity value by using tag comparison algorithm and template comparison algorithm. Textual similarity is computed by using cosine similarity, and hyperlink analysis is performed to compute outward links. The final similarity value is calculated by fusion of layout, text, hyperlink and EMD value. Once the similarity matrix is found clustering is employed with the help of connected component. Finally group of similar web pages i.e. summarized results get displayed to user. Experiment conducted to demonstrate the effectiveness of four methods to generate summarized result on different web pages and user queries also.

    2015-01-01

    Biomedical literature incorporates millions of figures, which are a rich and important knowledge resource for biomedical researchers. Scientists need access to the figures and the knowledge they represent in order to validate research findings and to generate new hypotheses. By themselves, these figures are nearly always incomprehensible to both humans and machines and their associated texts are therefore essential for full comprehension. The associated text of a figure, however, is scattered throughout its full-text article and contains redundant information content. In this paper, we report the continued development and evaluation of several figure summarization systems, the FigSum+ systems, that automatically identify associated texts, remove redundant information, and generate a text summary for every figure in an article. Using a set of 94 annotated figures selected from 19 different journals, we conducted an intrinsic evaluation of FigSum+. We evaluate the performance by precision, recall, F1, and ROUGE scores. The best FigSum+ system is based on an unsupervised method, achieving F1 score of 0.66 and ROUGE-1 score of 0.97. The annotated data is available at figshare.com (http://figshare.com/articles/Figure_Associated_Text_Summarization_and_Evaluation/858903).

    Full Text Available In this paper, we focus on video programs that are intended to disseminate information and knowledge such as news, documentaries, seminars, etc, and present an audiovisual summarization system that summarizes the audio and visual contents of the given video separately, and then integrating the two summaries with a partial alignment. The audio summary is created by selecting spoken sentences that best present the main content of the audio speech while the visual summary is created by eliminating duplicates/redundancies and preserving visually rich contents in the image stream. The alignment operation aims to synchronize each spoken sentence in the audio summary with its corresponding speaker′s face and to preserve the rich content in the visual summary. A Bipartite Graph-based audiovisual alignment algorithm is developed to efficiently find the best alignment solution that satisfies these alignment requirements. With the proposed system, we strive to produce a video summary that: (1 provides a natural visual and audio content overview, and (2 maximizes the coverage for both audio and visual contents of the original video without having to sacrifice either of them.

Everyone wants the latest in TVs, computers, mobiles, cars, household appliances, industrial machinery, the works.We want to hear the latest news. Nobody prefers to read yesterday's newspaper today out of choice. We also want to read the latest edition of a book, and look up recent references and research work.We want the latest in treatments as well. The most recent is always considered an advancement over what was available earlier. Newer therapies, newer investigations, newer procedures.But, at the some time, we want to go to the senior consultant. And, given a choice, the older the better. Even elsewhere, we do not go to the junior most person to solve our problems if we can approach the senior man, and he is amenable. The recent graduate or postgraduate has the latest information, but it is the senior man who sits on the panel of examiners.We want the most recent in some cases, and the older and more experienced in others. Why should this happen? How should we handle our great need to update our knowledge on the latest, and yet not neglect the old and time-tested?This dilemma occurs in the research field as well, and psychiatry is no exception.What can be a healthy way of resolving this issue is the subject matter of this monograph.

  20. Document summarization using positive pointwise mutual information

    CERN Document Server

    S, Aji

    2012-01-01

    The degree of success in document summarization processes depends on the performance of the method used in identifying significant sentences in the documents. The collection of unique words characterizes the major signature of the document, and forms the basis for Term-Sentence-Matrix (TSM). The Positive Pointwise Mutual Information, which works well for measuring semantic similarity in the Term-Sentence-Matrix, is used in our method to assign weights for each entry in the Term-Sentence-Matrix. The Sentence-Rank-Matrix generated from this weighted TSM, is then used to extract a summary from the document. Our experiments show that such a method would outperform most of the existing methods in producing summaries from large documents.

    2004-01-01

    We explore a knowledge-rich (abstraction) approach to summarization and apply it to multiple documents from an online medical encyclopedia. A semantic processor functions as the source interpreter and produces a list of predications. A transformation stage then generalizes and condenses this list, ultimately generating a conceptual condensate for a given disorder topic. We provide a preliminary evaluation of the quality of the condensates produced for a sample of four disorders. The overall precision of the disorder conceptual condensates was 87%, and the compression ratio from the base list of predications to the final condensate was 98%. The conceptual condensate could be used as input to a text generator to produce a natural language summary for a given disorder topic.

    2001-01-01

    This paper describes a video summarization and semantics editing tool that is suited for content-based video indexing and retrieval with appropriate human operator assistance. The whole system has been designed with a clear focus on the extraction and exploitation of motion information inherent in the dynamic video scene. The dominant motion information has ben used explicitly for shot boundary detection, camera motion characterization, visual content variations description, and for key frame extraction. Various contributions have been made to ensure that the system works robustly with complex scenes and across different media types. A window-based graphical user interface has been designed to make the task very easy for interactive analysis and editing of semantic events and episode where appropriate.

    2001-12-01

    To provide users with an overview of medical video content at various levels of abstraction which can be used for more efficient database browsing and access, a hierarchical video summarization strategy has been developed and is presented in this paper. To generate an overview, the key frames of a video are preprocessed to extract special frames (black frames, slides, clip art, sketch drawings) and special regions (faces, skin or blood-red areas). A shot grouping method is then applied to merge the spatially or temporally related shots into groups. The visual features and knowledge from the video shots are integrated to assign the groups into predefined semantic categories. Based on the video groups and their semantic categories, video summaries for different levels are constructed by group merging, hierarchical group clustering and semantic category selection. Based on this strategy, a user can select the layer of the summary to access. The higher the layer, the more concise the video summary; the lower the layer, the greater the detail contained in the summary.

    Full Text Available Like all good neighbours, competing schools of psychiatry claw at each other. Like all good samaritans, some people try to play arbiters and douse the fires. The tradition of fights and retaliation is not new to psy­chiatry, neither is it unique to the branch. Competing schools of thought exist almost everywhere. And it is tempting to say that the more intellec­tually robust a field, the greater the controversies and fights in it.In fact if intellectuals were to come together and not voice differences, either they are not intellectuals, or they have no opinions. (Or they may be simply scared, or silenced for other reasons.Ofcourse we must note that while in other fields of thought there can be controversies, there is one essential difference. They may not be dealing with patients and their lives. And to that the corollary is that psychiatric controversies should not be carried out at the expense of patient welfare.Having said that, let us also note that when there are fights, arbiters become very active. As do advocates, of one or the other approach.In this monograph we have tried to act the arbiters. Maybe because it is appropriate. Maybe also because that's the only thing we can do (and may be do well: atleast that's what we would love to believe.Why not advocates ? Well, for one, there are so many already. For another, we run the risk of doing a poor job of it.Not that we have necessarily done a good job of being arbiters.

    Information retrieval systems consist of many complicated components. Research and development of such systems is often hampered by the difficulty in evaluating how each particular component would behave across multiple systems. We present a novel hybrid information retrieval system--the Query, Cluster, Summarize (QCS) system--which is portable, modular, and permits experimentation with different instantiations of each of the constituent text analysis components. Most importantly, the combination of the three types of components in the QCS design improves retrievals by providing users more focused information organized by topic. We demonstrate the improved performance by a series of experiments using standard test sets from the Document Understanding Conferences (DUC) along with the best known automatic metric for summarization system evaluation, ROUGE. Although the DUC data and evaluations were originally designed to test multidocument summarization, we developed a framework to extend it to the task of evaluation for each of the three components: query, clustering, and summarization. Under this framework, we then demonstrate that the QCS system (end-to-end) achieves performance as good as or better than the best summarization engines. Given a query, QCS retrieves relevant documents, separates the retrieved documents into topic clusters, and creates a single summary for each cluster. In the current implementation, Latent Semantic Indexing is used for retrieval, generalized spherical k-means is used for the document clustering, and a method coupling sentence ''trimming'', and a hidden Markov model, followed by a pivoted QR decomposition, is used to create a single extract summary for each cluster. The user interface is designed to provide access to detailed information in a compact and useful format. Our system demonstrates the feasibility of assembling an effective IR system from existing software libraries, the usefulness of the modularity of

    2015-02-18

    A bibliometric analysis of the UK National Institute for Health Research (NIHR) Health Technology Assessment (HTA) monographs and their related journal articles by: (1) exploring the differences in citations to the HTA monographs in Google Scholar (GS), Scopus and Web of Science (WoS), and (2) comparing Scopus citations to the monographs with their related journal articles. A study of 111 HTA monographs published in 2010 and 2011, and their external journal articles. Citations to the monographs in GS, Scopus and WoS, and to their external journal articles in Scopus. The number of citations varied among the three databases, with GS having the highest and WoS the lowest; however, the citation-based rankings among the databases were highly correlated. Overall, 56% of monographs had a related publication, with the highest proportion for primary research (76%) and lowest for evidence syntheses (43%). There was a large variation in how the monographs were cited, compared to journal articles, resulting in more frequent problems, with unlinked citations in Scopus and WoS. When comparing differences in the number of citations between monograph publications with their related journal articles from the same project, we found that monographs received more citations than their journal articles for evidence syntheses and methodology projects; by contrast, journal articles related to primary research monographs were more highly cited than their monograph. The numbers of citations to the HTA monographs differed considerably between the databases, but were highly correlated. When a HTA monograph had a journal article from the same study, there were more citations to the journal article for primary research, but more to the monographs for evidence syntheses. Citations to the related journal articles were more reliably recorded than citations to the HTA monographs. Published by the BMJ Publishing Group Limited.

    Full Text Available In today's world, the rapid development of digital video and editing technology has led to fast growing of video data, creating the need for effective and advanced techniques for analysis and video retrieval, as multimedia repositories have made browsing, delivery of contents (video and video retrieval very slow. Hence, video summarization proposes various ways for faster browsing among a large amount of data and also for content indexing. Many people spend their free time to watch or play different sports like soccer, cricket, etc. but it is not possible to watch each and every game due to the longer timing of the game. In such cases, the users may just want to view the summary of the video that is just an abstract of the original video, instead of watching the whole video that provides more information about the occurrence of various incidents in the video. It is preferable to watch just highlights of the game or just review/trailer of a movie. Apparently, summarizing a video is an important process. In this paper, video summarization approaches are discussed, that can generate static or dynamic summaries. We present different techniques for each mode in literature. We have discussed some features used for generating video summaries. As soccer is the world’s most famous game played and watched, it is taken as a case study. Research done in this domain is discussed. We conclude that there is a broad perspective for further research in this field.

  16. Leveraging Usage Data for Linked Data Movie Entity Summarization

    2012-01-01

    Novel research in the field of Linked Data focuses on the problem of entity summarization. This field addresses the problem of ranking features according to their importance for the task of identifying a particular entity. Next to a more human friendly presentation, these summarizations can play a central role for semantic search engines and semantic recommender systems. In current approaches, it has been tried to apply entity summarization based on patterns that are inherent to the regarded data. The proposed approach of this paper focuses on the movie domain. It utilizes usage data in order to support measuring the similarity between movie entities. Using this similarity it is possible to determine the k-nearest neighbors of an entity. This leads to the idea that features that entities share with their nearest neighbors can be considered as significant or important for these entities. Additionally, we introduce a downgrading factor (similar to TF-IDF) in order to overcome the high number of commonly occurri...

    The National Toxicology Program conducted a cancer evaluation on 1 bromopropane for possible listing in the Report on Carcinogens (RoC). The cancer evaluation is captured in the RoC monograph, which was peer reviewed in a public forum. The monograph consists of two components: (Part 1) the cancer evaluation, which reviews the relevant scientific information, assesses its quality, applies the RoC listing criteria to the scientific information, and provides the NTP recommendation for listing status for 1 bromopropane in the RoC, and (Part 2) the substance profile proposed for the RoC, containing the NTP's listing status recommendation, a summary of the scientific evidence considered key to reaching that decision, and data on properties, use, production, exposure, and Federal regulations and guidelines to reduce exposure to 1-bromopropane. This monograph provides an assessment of the available scientific information on 1 bromopropane, including human exposure and properties, disposition and toxicokinetics, cancer studies in experimental animals, and studies of mechanisms and other related effects, including relevant toxicological effects, genetic toxicology, and mechanisms of carcinogenicity. From this assessment, the NTP recommended that 1 bromopropane be listed as reasonably anticipated to be a human carcinogen in the RoC based on sufficient evidence from studies in experimental animals, which found inhalation exposure to 1-bromopropane caused skin tumors in male rats, large intestine tumors in female and male rats, and lung tumors in female mice. Also noted was that 1 bromopropane, either directly or via reactive metabolites, caused molecular alterations that typically are associated with carcinogenesis, including genotoxicity, oxidative stress, and glutathione depletion. These alterations, observed in mainly in vitro and toxicity studies in rodents, are relevant to possible mechanisms of human carcinogenicity and support the relevance of the cancer studies in

This monograph provides an assessment of the available scientific information on cumene, including human exposure and properties, disposition and toxicokinetics, cancer studies in experimental animals, and studies of mechanisms and other related effects, including relevant toxicological effects, genetic toxicology, and mechanisms of carcinogenicity. From this assessment, the NTP recommended that cumene be listed as reasonably anticipated to be a human carcinogen in the RoC based on sufficient evidence from studies in experimental animals, which found that cumene exposure caused lung tumors in male and female mice and liver tumors in female mice. Several proposed mechanisms of carcinogenesis support the relevance to humans of the lung and liver tumors observed in experimental animals. Specifically, there is evidence that humans and experimental animals metabolize cumene through similar metabolic pathways. In addition, mutations of the K-ras oncogene and p53 tumor-suppressor gene observed in cumene-induced lung tumors in mice, along with altered expression of many other genes, resemble molecular alterations found in human lung and other cancers.

    Rautray, Rasmita; Balabantaray, Rakesh Chandra

    2017-07-01

    Today, World Wide Web has brought us enormous quantity of on-line information. As a result, extracting relevant information from massive data has become a challenging issue. In recent past text summarization is recognized as one of the solution to extract useful information from vast amount documents. Based on number of documents considered for summarization, it is categorized as single document or multi document summarization. Rather than single document, multi document summarization is more challenging for the researchers to find accurate summary from multiple documents. Hence in this study, a novel Cat Swarm Optimization (CSO) based multi document summarizer is proposed to address the problem of multi document summarization. The proposed CSO based model is also compared with two other nature inspired based summarizer such as Harmony Search (HS) based summarizer and Particle Swarm Optimization (PSO) based summarizer. With respect to the benchmark Document Understanding Conference (DUC) datasets, the performance of all algorithms are compared in terms of different evaluation metrics such as ROUGE score, F score, sensitivity, positive predicate value, summary accuracy, inter sentence similarity and readability metric to validate non-redundancy, cohesiveness and readability of the summary respectively. The experimental analysis clearly reveals that the proposed approach outperforms the other summarizers included in the study.

    Full Text Available A systematic and transparent layout of library material on book shelves of public libraries is one of the essential conditions for successful viewing and searching of materials. The research tried to determine the contemporary classification system of library material for the youth. The data needed for the research was gathered and analyzed by a questionnaire completed by five randomly selected central public libraries. Special collections, arrangement and classification of certain fiction and specialized monographic publications for infants, teenagers and adolescents were analyzed. It was of our interest to observe whether the libraries assign the elements of a call number - which are evident on the library material and in online catalogs – according to standards and current instructions. The article also focuses on the unity and differences of the technical processing, and on color and/or image of labels which additionally explain the classification and the contents of the monographic publications for the youth.

    This review examines work on automated summarization of electronic health record (EHR) data and in particular, individual patient record summarization. We organize the published research and highlight methodological challenges in the area of EHR summarization implementation. The target audience for this review includes researchers, designers, and informaticians who are concerned about the problem of information overload in the clinical setting as well as both users and developers of clinical summarization systems. Automated summarization has been a long-studied subject in the fields of natural language processing and human-computer interaction, but the translation of summarization and visualization methods to the complexity of the clinical workflow is slow moving. We assess work in aggregating and visualizing patient information with a particular focus on methods for detecting and removing redundancy, describing temporality, determining salience, accounting for missing data, and taking advantage of encoded clinical knowledge. We identify and discuss open challenges critical to the implementation and use of robust EHR summarization systems. © The Author 2015.

    2014-10-28

    The European Directive 2004/24/EC introducing a simplified registration procedure for traditional herbal medicinal products, plays an important role in harmonising the current legislation framework for all herbal medicinal products in the European Union (EU). Although substantial achievements have been made under the new scheme, only a limited number of herbal medicinal products from non-European traditions commonly used in Europe have been registered. Therefore, identification of the obstacles, and determination of appropriate means to overcome the major challenges in the registration of non-European traditional herbal medicinal products are of critical importance for the EU herbal medicinal product market. The primary aims of this study were to understand the key issues and obstacles to registration of non-European traditional herbal medicinal products within the EU. The findings may identify the need for more attention on the Community herbal monographs elaborated by the Herbal Medicinal Products Committee (HMPC), as well as further evidence based scientific research on non-European herbal substances/preparations by the scientific community. A systematic evaluation of the herbal substances and preparations included in Community herbal monographs and public statements has been carried out. The focus was herbal substances and preparations derived from non-European traditions. Of the 109 adopted Community herbal monographs, 10 are herbal substances used in Chinese traditional medicine. Where the HMPC issued a public statement because it was unable to elaborate a monograph more than half-involved herbal substances/preparations from non-European traditions. The main reasons herbal substances/preparations from non-European traditions were not accepted for inclusion in the Community herbal monographs have been identified as due to unfulfilled requirements of Directive 2004/24/EC. The most common reasons were the lack of evidence to demonstrate a 15-year minimum

    The current USP National Formulary contains 65 Monographs for drug formulations containing neomycin. All 65 Monographs prescribe a bioassay for neomycin assay. This bioassay, based on cell culture, is labor intensive, has poor precision, and cannot be adapted for purity or identification. High-performance anion-exchange chromatography with integrated pulsed amperometric detection (HPAE-IPAD), a liquid chromatography technique, has been shown to be suitable for neomycin purity analysis and neomycin assay of an over-the-counter first aid cream (Hanko and Rohrer [17]). Here we propose that an HPAE-IPAD assay can replace the bioassay in the 65 neomycin-containing Monographs. We applied the HPAE-IPAD assay to four neomycin-containing drug products representing the four classes of formulations found in the 65 Monographs, liquid, solid, suspension, and cream. Each drug was analyzed with two chromatography systems, and on 3 separate days. For all products, HPAE-IPAD measurements were precise and accurate with respect to the label concentrations. There was also high accuracy for spike recovery of neomycin from the four drug products throughout 70-150% of the labeled concentration. These results suggest that an HPAE-IPAD assay would be an accurate assay for neomycin, and would be faster and more precise than the current bioassay.

    Full Text Available Many of previous research have proven that the usage of rhetorical relations is capable to enhance many applications such as text summarization, question answering and natural language generation. This work proposes an approach that expands the benefit of rhetorical relations to address redundancy problem for cluster-based text summarization of multiple documents. We exploited rhetorical relations exist between sentences to group similar sentences into multiple clusters to identify themes of common information. The candidate summary were extracted from these clusters. Then, cluster-based text summarization is performed using Conditional Markov Random Walk Model to measure the saliency scores of the candidate summary. We evaluated our method by measuring the cohesion and separation of the clusters constructed by exploiting rhetorical relations and ROUGE score of generated summaries. The experimental result shows that our method performed well which shows promising potential of applying rhetorical relation in text clustering which benefits text summarization of multiple documents

    The realization that statistical physics methods can be applied to analyze written texts represented as complex networks has led to several developments in natural language processing, including automatic summarization and evaluation of machine translation. Most importantly, so far only a few metrics of complex networks have been used and therefore there is ample opportunity to enhance the statistics-based methods as new measures of network topology and dynamics are created. In this paper, we employ for the first time the metrics betweenness, vulnerability and diversity to analyze written texts in Brazilian Portuguese. Using strategies based on diversity metrics, a better performance in automatic summarization is achieved in comparison to previous work employing complex networks. With an optimized method the Rouge score (an automatic evaluation method used in summarization) was 0.5089, which is the best value ever achieved for an extractive summarizer with statistical methods based on complex networks for Brazilian Portuguese. Furthermore, the diversity metric can detect keywords with high precision, which is why we believe it is suitable to produce good summaries. It is also shown that incorporating linguistic knowledge through a syntactic parser does enhance the performance of the automatic summarizers, as expected, but the increase in the Rouge score is only minor. These results reinforce the suitability of complex network methods for improving automatic summarizers in particular, and treating text in general.

  3. WEB DOCUMENT SEGMENTATION USING FREQUENT TERM SETS FOR SUMMARIZATION

    Full Text Available Query sensitive summarization aims at extracting the query relevant contents from web documents. Web page segmentation focuses on reducing the run time overhead of the summarization systems by grouping the related contents of a web page into segments. At query time, query relevant segments of the web page are identified and important sentences from these segments are extracted to compose the summary. DOM tree structures of the web documents are utilized to perform the segmentation of the contents. Leaf nodes of DOM tress are merged to form segments according to the statistical and linguistic similarity measure. The proposed system has been evaluated by intrinsic approach making use of user satisfaction index. The performance of the system is compared with summarization without using preprocessed segments. Performance of this system is more promising than the other measures like cosine similarity, jaccard measure which make use of sparse term-frequent vectors, since the most frequent term sets are considered to measure the relevance. Relevant segments alone need to be processed at run time for summarization which reduces the time complexity of the summarization process.

  4. Syntactic and Sentence Feature Based Hybrid Approach for Text Summarization

    Full Text Available Recently, there has been a significant research in automatic text summarization using feature-based techniques in which most of them utilized any one of the soft computing techniques. But, making use of syntactic structure of the sentences for text summarization has not widely applied due to its difficulty of handling it in summarization process. On the other hand, feature-based technique available in the literature showed efficient results in most of the techniques. So, combining syntactic structure into the feature-based techniques is surely smooth the summarization process in a way that the efficiency can be achieved. With the intention of combining two different techniques, we have presented an approach of text summarization that combines feature and syntactic structure of the sentences. Here, two neural networks are trained based on the feature score and the syntactic structure of sentences. Finally, the two neural networks are combined with weighted average to find the sentence score of the sentences. The experimentation is carried out using DUC 2002 dataset for various compression ratios. The results showed that the proposed approach achieved F-measure of 80% for the compression ratio 50 % that proved the better results compared with the existing techniques.

    2017-01-01

    Full Text Available In order to reduce the redundancy of answer summary generated from community q&a dataset without topic tags, we propose an answer summarization algorithm based on keyword extraction. We combine tf-idf with word vector to change the influence transferred ratio equation in TextRank. And then during summarizing, we take the ratio of the number of sentences containing any keyword to the total number of candidate sentences as an adaptive factor for AMMR. Meanwhile we reuse the scores of keywords generated by TextRank as a weight factor for sentence similarity computing. Experimental results show that the proposed answer summarization is better than the traditional MMR and AMMR.

    2016-01-01

    Full Text Available Text summarization is to generate a condensed version of the original document. The major issues for text summarization are eliminating redundant information, identifying important difference among documents, and recovering the informative content. This paper proposes a Semantic Graph Model which exploits the semantic information of sentence using FSGM. FSGM treats sentences as vertexes while the semantic relationship as the edges. It uses FrameNet and word embedding to calculate the similarity of sentences. This method assigns weight to both sentence nodes and edges. After all, it proposes an improved method to rank these sentences, considering both internal and external information. The experimental results show that the applicability of the model to summarize text is feasible and effective.

    This paper will be submitted to the proceedings The Eleventh IASTED International Conference on. Signal and Image Processing. Given a video or video archive how does one effectively and quickly summarize, classify, and search the information contained within the data? This paper addresses these issues by describing a process for the automated generation of a table-of-contents and keyword, topic-based index tables that can be used to catalogue, summarize, and search large amounts of video data. Having the ability to index and search the information contained within the videos, beyond just metadata tags, provides a mechanism to extract and identify "useful" content from image and video data.

    Ten years have passed since Directive 2004/24/EC regulating herbal medicinal products across the EU were published. The directive created the Committee on Herbal Medicinal Products within the European Medicines Agency whose remit includes the creation and publishing of official EU monographs on herbal medicinal products. These monographs include the official uses of the products and their evidence for efficacy and safety. To this effect, we are interested in analysing the potential impact herbal product EU monographs could have on the therapeutic treatment options available for prescribers in Malta. Therefore our aim was two-fold. First, to rationalise the spread of indications of the herbal substances listed in the community herbal monograph inventory and subsequently determine if these herbal substances could potentially contribute to the treatment options available in our local scenario (Malta). 128 EU monographs were analysed resulting in a total of 230 indications which subsequently codified into 42 unique ATC codes. The Malta Medicines List contains 1456 unique ATC codes. Comparative analysis of the Malta Medicines List revealed that the 21 therapeutic areas had 4 or less pharmaceutically used substances (5th level ATC codes) registered and therefore in our opinion are areas with limited therapeutic choice. The following 4 therapeutic areas, A05 bile and liver therapy, A13 tonics, A15 appetite stimulants and D03 preparations for treatment of wounds and ulcers, could potentially benefit from the registration of herbal medicinal products according to the EU herbal monographs. If such registration is effected the aforementioned areas would no longer be considered limited because more than 4 therapeutic choices would be available to prescribers. This study is the first study across the EU to analyse the potential impact of published EU herbal monographs on therapeutic coverage in an EU member state and confirms the notion that herbal products could potentially

    Full Text Available The outbreak of unexpected news events such as large human accident or natural disaster brings about a new information access problem where traditional approaches fail. Mostly, news of these events shows characteristics that are early sparse and later redundant. Hence, it is very important to get updates and provide individuals with timely and important information of these incidents during their development, especially when being applied in wireless and mobile Internet of Things (IoT. In this paper, we define the problem of sequential update summarization extraction and present a new hierarchical update mining system which can broadcast with useful, new, and timely sentence-length updates about a developing event. The new system proposes a novel method, which incorporates techniques from topic-level and sentence-level summarization. To evaluate the performance of the proposed system, we apply it to the task of sequential update summarization of temporal summarization (TS track at Text Retrieval Conference (TREC 2013 to compute four measurements of the update mining system: the expected gain, expected latency gain, comprehensiveness, and latency comprehensiveness. Experimental results show that our proposed method has good performance.

  14. Enhancing biomedical text summarization using semantic relation extraction.

    Directory of Open Access Journals (Sweden)

    Yue Shang

    Full Text Available Automatic text summarization for a biomedical concept can help researchers to get the key points of a certain topic from large amount of biomedical literature efficiently. In this paper, we present a method for generating text summary for a given biomedical concept, e.g., H1N1 disease, from multiple documents based on semantic relation extraction. Our approach includes three stages: 1 We extract semantic relations in each sentence using the semantic knowledge representation tool SemRep. 2 We develop a relation-level retrieval method to select the relations most relevant to each query concept and visualize them in a graphic representation. 3 For relations in the relevant set, we extract informative sentences that can interpret them from the document collection to generate text summary using an information retrieval based method. Our major focus in this work is to investigate the contribution of semantic relation extraction to the task of biomedical text summarization. The experimental results on summarization for a set of diseases show that the introduction of semantic knowledge improves the performance and our results are better than the MEAD system, a well-known tool for text summarization.

    2013-11-01

    Genome-wide association studies, which typically report regression coefficients summarizing the associations of many genetic variants with various traits, are potentially a powerful source of data for Mendelian randomization investigations. We demonstrate how such coefficients from multiple variants can be combined in a Mendelian randomization analysis to estimate the causal effect of a risk factor on an outcome. The bias and efficiency of estimates based on summarized data are compared to those based on individual-level data in simulation studies. We investigate the impact of gene-gene interactions, linkage disequilibrium, and 'weak instruments' on these estimates. Both an inverse-variance weighted average of variant-specific associations and a likelihood-based approach for summarized data give similar estimates and precision to the two-stage least squares method for individual-level data, even when there are gene-gene interactions. However, these summarized data methods overstate precision when variants are in linkage disequilibrium. If the P-value in a linear regression of the risk factor for each variant is less than 1×10⁻⁵, then weak instrument bias will be small. We use these methods to estimate the causal association of low-density lipoprotein cholesterol (LDL-C) on coronary artery disease using published data on five genetic variants. A 30% reduction in LDL-C is estimated to reduce coronary artery disease risk by 67% (95% CI: 54% to 76%). We conclude that Mendelian randomization investigations using summarized data from uncorrelated variants are similarly efficient to those using individual-level data, although the necessary assumptions cannot be so fully assessed. © 2013 WILEY PERIODICALS, INC.

    Constant working surveillance cameras in public places, such as airports and banks, produce huge amount of video data. Faces in such videos can be extracted in real time. However, most of these detected faces are either redundant or useless. Redundant information adds computational costs to facial...... analysis systems and useless data makes the final results of such systems noisy, unstable, and erroneous. Thus, there is a need for a mechanism to summarize the original video sequence to a set of the most expressive images of the sequence.

The summarized results of this technique have been used in three different facial analysis systems and the experimental results on real video sequences are promising....

  19. Generalized minimum dominating set and application in automatic text summarization

    CERN Document Server

    Xu, Yi-Zhi

    2016-01-01

    For a graph formed by vertices and weighted edges, a generalized minimum dominating set (MDS) is a vertex set of smallest cardinality such that the summed weight of edges from each outside vertex to vertices in this set is equal to or larger than certain threshold value. This generalized MDS problem reduces to the conventional MDS problem in the limiting case of all the edge weights being equal to the threshold value. We treat the generalized MDS problem in the present paper by a replica-symmetric spin glass theory and derive a set of belief-propagation equations. As a practical application we consider the problem of extracting a set of sentences that best summarize a given input text document. We carry out a preliminary test of the statistical physics-inspired method to this automatic text summarization problem.

    2016-10-05

    Video summarization is a timely and rapidly developing research field with broad commercial interest, due to the increasing availability of massive video data. Relevant algorithms face the challenge of needing to achieve a careful balance between summary compactness, enjoyability and content coverage. The specific case of stereoscopic 3D theatrical films has become more important over the past years, but not received corresponding research attention. In the present work, a multi-stage, multimodal summarization process for such stereoscopic movies is proposed, that is able to extract a short, representative video skim conforming to narrative characteristics from a 3D film. At the initial stage, a novel, low-level video frame description method is introduced (Frame Moments Descriptor, or FMoD), that compactly captures informative image statistics from luminance, color, optical flow and stereoscopic disparity video data, both in a global and in a local scale. Thus, scene texture, illumination, motion and geometry properties may succinctly be contained within a single frame feature descriptor, which can subsequently be employed as a building block in any key-frame extraction scheme, e.g., for intra-shot frame clustering. The computed key-frames are then used to construct a movie summary in the form of a video skim, which is post-processed in a manner that also takes into account the audio modality. The next stage of the proposed summarization pipeline essentially performs shot pruning, controlled by a userprovided shot retention parameter, that removes segments from the skim based on the narrative prominence of movie characters in both the visual and the audio modalities. This novel process (Multimodal Shot Pruning, or MSP) is algebraically modelled as a multimodal matrix Column Subset Selection Problem, which is solved using an evolutionary computing approach. Subsequently, disorienting editing effects induced by summarization are dealt with, through manipulation of

    Image resizing can be more effectively achieved with a better understanding of image semantics. In this paper, similar patterns that exist in many real-world images are analyzed. By interactively detecting similar objects in an image, the image content can be summarized rather than simply distorted or cropped. This method enables the manipulation of image pixels or patches as well as semantic objects in the scene during image resizing process. Given the special nature of similar objects in a general image, the integration of a novel object carving (OC) operator with the multi-operator framework is proposed for summarizing similar objects. The object removal sequence in the summarization strategy directly affects resizing quality. The method by which to evaluate the visual importance of the object as well as to optimally select the candidates for object carving is demonstrated. To achieve practical resizing applications for general images, a template matching-based method is developed. This method can detect similar objects even when they are of various colors, transformed in terms of perspective, or partially occluded. To validate the proposed method, comparisons with state-of-the-art resizing techniques and a user study were conducted. Convincing visual results are shown to demonstrate the effectiveness of the proposed method.

    As the Internet and multimedia technology is becoming advanced, the number of digital multimedia contents is also becoming abundant in learning area. In order to facilitate the access of digital knowledge and to meet the need of a lifelong learning, e-learning could be the helpful alternative way to the conventional learning paradigms. E-learning is known as a unifying term to express online, web-based and technology-delivered learning. Mobile-learning (m-learning) is defined as e-learning through mobile devices using wireless transmission. In a survey, more than half of the people remarked that the re-consumption was one of the convenient features in e-learning. However, it is not easy to find user's preferred segmentation from a full version of lengthy e-learning content. Especially in m-learning, a content-summarization method is strongly required because mobile devices are limited to low processing power and battery capacity. In this paper, we propose a new user preference model for re-consumption to construct personalized summarization for re-consumption. The user preference for re-consumption is modeled based on user actions with statistical model. Based on the user preference model for re-consumption with personalized user actions, our method discriminates preferred parts over the entire content. Experimental results demonstrated successful personalized summarization.

    The easily recognised genus Otidea is subjected to numerous problems in species identification. A number of old names have undergone various interpretations, materials from different continents have not been compared and misidentifications occur commonly. In this context, Otidea is monographed, based on our multiple gene phylogenies assessing species boundaries and comparative morphological characters (see Hansen & Olariaga 2015). All names combined in or synonymised with Otidea are dealt with. Thirty-three species are treated, with full descriptions and colour illustrations provided for 25 of these. Five new species are described, viz. O. borealis, O. brunneoparva, O. oregonensis, O. pseudoleporina and O. subformicarum. Otidea cantharella var. minor and O. onotica var. brevispora are elevated to species rank. Otideopsis kaushalii is combined in the genus Otidea. A key to the species of Otidea is given. An LSU dataset containing 167 sequences (with 44 newly generated in this study) is analysed to place collections and determine whether the named Otidea sequences in GenBank were identified correctly. Fourty-nine new ITS sequences were generated in this study. The ITS region is too variable to align across Otidea, but had low intraspecific variation and it aided in species identifications. Thirty type collections were studied, and ITS and LSU sequences are provided for 12 of these. A neotype is designated for O. cantharella and epitypes for O. concinna, O. leporina and O. onotica, along with several lectotypifications. The apothecial colour and shape, and spore characters are important for species identification. We conclude that to distinguish closely related or morphologically similar species, a combination of additional features are needed, i.e. the shape of the paraphyses, ectal excipulum structure, types of ectal excipulum resinous exudates and their reactions in Melzer's reagent and KOH, tomentum and basal mycelium colours and exudates.

  8. Summarization of Surveillance Video Sequences Using Face Quality Assessment

    DEFF Research Database (Denmark)

    Nasrollahi, Kamal; Moeslund, Thomas B.; Rahmati, Mohammad

    2011-01-01

    Constant working surveillance cameras in public places, such as airports and banks, produce huge amount of video data. Faces in such videos can be extracted in real time. However, most of these detected faces are either redundant or useless. Redundant information adds computational costs to facial...... analysis systems and useless data makes the final results of such systems noisy, unstable, and erroneous. Thus, there is a need for a mechanism to summarize the original video sequence to a set of the most expressive images of the sequence. The proposed system in this paper uses a face quality assessment...

    For many Web-based applications, it's important to be able to analyze the paths users have taken through a site--for example, to understand how they're discovering engaging content. These paths are difficult to summarize visually because of the underlying data's complexity. A Google researcher applied a sunburst visualization to this problem, after simplifying the data into a hierarchical format. The resulting visualization was successful in YouTube and is widely referenced and accessed. The code for the visualization is available as open source.

  12. Towards an Automatic Forum Summarization to Support Tutoring

    Science.gov (United States)

    Carbonaro, Antonella

    The process of summarizing information is becoming increasingly important in the light of recent advances in resource creation and distribution and the resulting influx of large numbers of information in everyday life. These advances are also challenging educational institutions to adopt the opportunities of distributed knowledge sharing and communication. Among the most recent trends, the availability of social communication networks, knowledge representation and of activate learning gives rise for a new landscape of learning as a networked, situated, contextual and life-long activities. In this scenario, new perspectives on learning and teaching processes must be developed and supported, relating learning models, content-based tools, social organization and knowledge sharing.

    2006-01-01

    The association between social determinants and health inequalities is well recognized. What are now needed are tools to assist in disseminating such information. This article describes how the Balanced Scorecard may be used for summarizing data on health inequalities. The process begins by selecting appropriate social groups and indicators, and is followed by the measurement of differences across person, place, or time. The next step is to decide whether to focus on absolute versus relative inequality. The last step is to determine the scoring method, including whether to address issues of depth of inequality.

    1998-10-01

    This paper investigates clustering techniques as a method of organizing image databases to support popular visual management functions such as searching, browsing and navigation. Different types of hierarchical agglomerative clustering techniques are studied as a method of organizing features space as well as summarizing image groups by the selection of a few appropriate representatives. Retrieval performance using both single and multiple level hierarchies are experimented with and the algorithms show an interesting relationship between the top k correct retrievals and the number of comparisons required. Some arguments are given to support the use of such cluster-based techniques for managing distributed image databases.

    2013-11-01

    Full Text Available In this paper, we describe the design and evaluation of extractive summarization approach to assist the learners with reading difficulties. As existing summarization approaches inherently assign more weights to the important sentences, our approach predicts the summary sentences that are important as well as readable to the target audience with good accuracy. We used supervised machine learning technique for summary extraction of science and social subjects in the educational text. Various independent features from the existing literature for predicting important sentences and proposed learner dependent features for predicting readable sentences are extracted from texts and are used for automatic classification. We performed both extrinsic and intrinsic evaluation on this approach and the intrinsic evaluation is carried out using F-measure and readability analysis. The extrinsic evaluation comprises of learner feedback using likert scale and the effect of assistive summary on improving readability for learners’ with reading difficulty using ANOVA. The results show significant improvement in readability for the target audience using assistive summary.

    2009-01-01

    Engineering and research teams often develop new products and technologies by referring to inventions described in patent databases. Efficient patent analysis builds R&D knowledge, reduces new product development time, increases market success, and reduces potential patent infringement. Thus, it is beneficial to automatically and systematically extract information from patent documents in order to improve knowledge sharing and collaboration among R&D team members. In this research, patents are summarized using a combined ontology based and TF-IDF concept clustering approach. The ontology captures the general knowledge and core meaning of patents in a given domain. Then, the proposed methodology extracts, clusters, and integrates the content of a patent to derive a summary and a cluster tree diagram of key terms. Patents from the International Patent Classification (IPC) codes B25C, B25D, B25F (categories for power hand tools) and B24B, C09G and H011 (categories for chemical mechanical polishing) are used as case studies to evaluate the compression ratio, retention ratio, and classification accuracy of the summarization results. The evaluation uses statistics to represent the summary generation and its compression ratio, the ontology based keyword extraction retention ratio, and the summary classification accuracy. The results show that the ontology based approach yields about the same compression ratio as previous non-ontology based research but yields on average an 11% improvement for the retention ratio and a 14% improvement for classification accuracy.

  17. An unsupervised method for summarizing egocentric sport videos

    Habibi Aghdam, Hamed; Jahani Heravi, Elnaz; Puig, Domenec

    2015-12-01

    People are getting more interested to record their sport activities using head-worn or hand-held cameras. This type of videos which is called egocentric sport videos has different motion and appearance patterns compared with life-logging videos. While a life-logging video can be defined in terms of well-defined human-object interactions, notwithstanding, it is not trivial to describe egocentric sport videos using well-defined activities. For this reason, summarizing egocentric sport videos based on human-object interaction might fail to produce meaningful results. In this paper, we propose an unsupervised method for summarizing egocentric videos by identifying the key-frames of the video. Our method utilizes both appearance and motion information and it automatically finds the number of the key-frames. Our blind user study on the new dataset collected from YouTube shows that in 93:5% cases, the users choose the proposed method as their first video summary choice. In addition, our method is within the top 2 choices of the users in 99% of studies.

    2012-01-01

    Schema summarization on large-scale databases is a challenge.In a typical large database schema,a great proportion of the tables are closely connected through a few high degree tables.It is thus difficult to separate these tables into clusters that represent different topics.Moreover,as a schema can be very big,the schema summary needs to be structured into multiple levels,to further improve the usability.In this paper,we introduce a new schema summarization approach utilizing the techniques of community detection in social networks.Our approach contains three steps.First,we use a community detection algorithm to divide a database schema into subject groups,each representing a specific subject.Second,we cluster the subject groups into abstract domains to form a multi-level navigation structure.Third,we discover representative tables in each cluster to label the schema summary.We evaluate our approach on Freebase,a real world large-scale database.The results show that our approach can identify subject groups precisely.The generated abstract schema layers are very helpful for users to explore database.

    2005-01-01

    This paper reports part of a study to develop a method for automatic multi-document summarization. The current focus is on dissertation abstracts in the field of sociology. The summarization method uses macro-level and micro-level discourse structure to identify important information that can be extracted from dissertation abstracts, and then uses a variable-based framework to integrate and organize extracted information across dissertation abstracts. This framework focuses more on research concepts and their research relationships found in sociology dissertation abstracts and has a hierarchical structure. A taxonomy is constructed to support the summarization process in two ways: (1) helping to identify important concepts and relations expressed in the text, and (2) providing a structure for linking similar concepts in different abstracts. This paper describes the variable-based framework and the summarization process, and then reports the construction of the taxonomy for supporting the summarization process. An example is provided to show how to use the constructed taxonomy to identify important concepts and integrate the concepts extracted from different abstracts.

  2. Use of High Throughput Screening Data in IARC Monograph ...

    Science.gov (United States)

    Purpose: Evaluation of carcinogenic mechanisms serves a critical role in IARC monograph evaluations, and can lead to “upgrade” or “downgrade” of the carcinogenicity conclusions based on human and animal evidence alone. Three recent IARC monograph Working Groups (110, 112, and 113) pioneered analysis of high throughput in vitro screening data from the U.S. Environmental Protection Agency’s ToxCast program in evaluations of carcinogenic mechanisms. Methods: For monograph 110, ToxCast assay data across multiple nuclear receptors were used to test the hypothesis that PFOA acts exclusively through the PPAR family of receptors, with activity profiles compared to several prototypical nuclear receptor-activating compounds. For monographs 112 and 113, ToxCast assays were systematically evaluated and used as an additional data stream in the overall evaluation of the mechanistic evidence. Specifically, ToxCast assays were mapped to 10 “key characteristics of carcinogens” recently identified by an IARC expert group, and chemicals’ bioactivity profiles were evaluated both in absolute terms (number of relevant assays positive for bioactivity) and relative terms (ranking with respect to other compounds evaluated by IARC, using the ToxPi methodology). Results: PFOA activates multiple nuclear receptors in addition to the PPAR family in the ToxCast assays. ToxCast assays offered substantial coverage for 5 of the 10 “key characteristics,” with the greates

    Sun, Yan; Hu, Kongfa; Lu, Zhipeng; Zhao, Li; Chen, Ling

    Radio Frequency Identification (RFID) applications are set to play an essential role in object tracking and supply chain management systems. The volume of data generated by a typical RFID application will be enormous as each item will generate a complete history of all the individual locations that it occupied at every point in time. The movement trails of such RFID data form gigantic commodity flowgraph representing the locations and durations of the path stages traversed by each item. In this paper, we use graph to construct a warehouse of RFID commodity flows, and introduce a database-style operation to summarize graphs, which produces a summary graph by grouping nodes based on user-selected node attributes, further allows users to control the hierarchy of summaries. It can cut down the size of graphs, and provide convenience for users to study just on the shrunk graph which they interested. Through extensive experiments, we demonstrate the effectiveness and efficiency of the proposed method.

    Patients have to be respected with dignity as the masters of their own lives. The problem, however, is that autonomy may become so dominant and the fundamental value of caring in professional nursing that the patient's dignity is affected. The aim of this article is to point out some of the issues with the interplay between autonomy, also called self-management and dignity. Given voice to the patient perspective the background is provided by cases from research conducted through qualitative interviews with patients and expanded by summarizing empirical research concerning the interplay between autonomy and dignity. The search strategy and the research question gave five empirical research papers and three theoretical studies and concept analyses. A concise overview of the relevant research contains information about all the major elements of the studies. The background research and an interpretative summary address new issues to be taken into account in dignity conserving care.

    Full Text Available The volume of published biomedical literature on disease related knowledge is expanding rapidly. Traditional information retrieval (IR techniques, when applied to large databases such as PubMed, often return large, unmanageable lists of citations that do not fulfill the searcher’s information needs. In this paper, we present an approach to automatically construct disease related knowledge summarization from biomedical literature. In this approach, firstly Kullback-Leibler Divergence combined with mutual information metric is used to extract disease salient information. Then deep search based on depth first search (DFS is applied to find hidden (indirect relations between biomedical entities. Finally random walk algorithm is exploited to filter out the weak relations. The experimental results show that our approach achieves a precision of 60% and a recall of 61% on salient information extraction for Carcinoma of bladder and outperforms the method of Combo.

  13. Dynamic key-frame extraction for video summarization

    Science.gov (United States)

    Ciocca, Gianluigi; Schettini, Raimondo

    2005-01-01

    We propose an innovative approach to the selection of representative frames of a video shot for video summarization. By analyzing the differences between two consecutive frames of a video sequence, the algorithm determines the complexity of the sequence in terms of visual content changes. Three descriptors are used to express the frame"s visual content: a color histogram, wavelet statistics and an edge direction histogram. Similarity measures are computed for each descriptor and combined to form a frame difference measure. The use of multiple descriptors provides a more precise representation, capturing even small variations in the frame sequence. This method can dynamically, and rapidly select a variable number of key frame within each shot, and does not exhibit the complexity of existing methods based on clustering algorithm strategies.

    Science.gov (United States)

    2013-05-01

    The National Toxicology Program (NTP) Office of Health Assessment and Translation (OHAT) conducted an evaluation of the developmental effects and pregnancy outcomes associated with cancer chemotherapy use during pregnancy in humans. The final NTP monograph was completed in May 2013 (available at http:// ntp.niehs.nih.gov/go/36495). The incidence of cancer during pregnancy has been reported to occur from 17 to 100 per 100,000 pregnant women. Chemotherapy is a common treatment for cancer; however, most chemotherapy agents are classified as known or suspected human teratogens. Cancer chemotherapy use during pregnancy was selected for evaluation by the NTP because of the: (1) paucity of comprehensive reviews on the pregnancy outcomes following cancer chemotherapy use during pregnancy in humans, including the integration of the developmental animal toxicology literature with the observational studies in humans, and (2) growing public interest in the developmental effects of chemotherapy on offspring exposed to cancer chemotherapy during gestation due to the expected incidence of cancer diagnosed during pregnancy as women delay pregnancy to later ages. Of the approximately 110 cancer chemotherapeutic agents currently in use, the NTP monograph includes data on 56 agents used during 1,261 pregnancies for which pregnancy outcomes were documented. Overall, the NTP evaluation found that treatment with chemotherapy for cancer appeared to be associated with: (1) a higher rate of major malformations following exposure during the first trimester compared to exposure in the second and/or third trimester; (2) an increase the rate of stillbirth following exposure in the second and/ or third trimester; abnormally low levels of amniotic fluid (primarily attributable to Trastuzumab); and (3), also data are insufficient, impaired fetal growth and myelosuppression.

    2012-05-01

    Full Text Available Recent developments in digital video and drastic increase of internet use have increased the amount of people searching and watching videos online. In order to make the search of the videos easy, Summary of the video may be provided along with each video. The video summary provided thus should be effective so that the user would come to know the content of the video without having to watch it fully. The summary produced should consists of the key frames that effectively express the content and context of the video. This work suggests a method to extract key frames which express most of the information in the video. This is achieved by quantifying Visual attention each frame commands. Visual attention of each frame is quantified using a descriptor called Attention quantifier. This quantification of visual attention is based on the human attention mechanism that indicates color conspicuousness and the motion involved seek more attention. So based on the color conspicuousness and the motion involved each frame is given a Attention parameter. Based on the attention quantifier value the key frames are extracted and are summarized adaptively. This framework suggests a method to produces meaningful video summary.

  16. Monograph use at an academic health sciences library: the first three years of shelf life

    Blecic, Deborah D.

    2000-01-01

    Objective: To study the circulation of monographs during the first three years of shelf life at an academic health sciences library. Method: A record was kept of monographs added to the circulating collection from mid-1994 to mid-1995. After three years, each monograph was located and the number of times it circulated during the first, second, and third year of shelf life determined by counting checkout stamps on the circulation slip. Results: Of the 1,958 monographs studied, 1,674 had complete data for the first three years of shelf life. Of those 1,674 titles, 81.48% circulated at least once. A total of 7,659 circulations were recorded; 38.69% occurred in the first year of shelf life, 32.37% in the second year, and 28.95% in the third year. The data did not fit the well-known 80/20 rule. Instead, approximately 38% of monographs accounted for 80% of circulation. A small percentage, 2.21%, of monographs accounted for a substantial percentage of circulation, 21.84%. Conclusions: A large percentage of the monographs circulated and use did not decline sharply with age within the first three years of shelf life, indicating a high demand for monographs at this academic health sciences library. These results, combined with the findings of earlier studies, suggested two possibilities. First, academic health sciences libraries might exhibit use of a higher percentage of monograph acquisitions than other types of libraries; or, second, a low monograph-to-user ratio might result in a higher percentage of monographs being used. Perhaps both factors contributed to the results found in this study. Further investigation would be needed to determine the extent to which library type and monograph-to-user ratio influenced monograph use. PMID:10783969

    Evidence regarding carcinogenic mechanisms serves a critical role in International Agency for Research on Cancer (IARC) Monograph evaluations. Three recent IARC Working Groups pioneered inclusion of the US Environmental Protection Agency (EPA) ToxCast program high-throughput screening (HTS) data to supplement other mechanistic evidence. In Monograph V110, HTS profiles were compared between perfluorooctanoic acid (PFOA) and prototypical activators across multiple nuclear receptors. For Monograph V112 -113, HTS assays were mapped to 10 key characteristics of carcinogens identified by an IARC expert group, and systematically considered as an additional mechanistic data stream. Both individual assay results and ToxPi-based rankings informed mechanistic evaluations. Activation of multiple nuclear receptors in HTS assays showed that PFOA targets peroxisome proliferator activated and other receptors. ToxCast assays substantially covered 5 of 10 key characteristics, corroborating literature evidence of "induces oxidative stress" and "alters cell proliferation, cell death or nutrient supply" and filling gaps for "modulates receptor-mediated effects." Thus, ToxCast HTS data were useful both in evaluating specific mechanistic hypotheses and in the overall evaluation of mechanistic evidence. However, additional HTS assays are needed to provide more comprehensive coverage of the 10 key characteristics of carcinogens that form the basis of current IARC mechanistic evaluations.

  19. A novel tool for assessing and summarizing the built environment

    2012-10-01

    Full Text Available Abstract Background A growing corpus of research focuses on assessing the quality of the local built environment and also examining the relationship between the built environment and health outcomes and indicators in communities. However, there is a lack of research presenting a highly resolved, systematic, and comprehensive spatial approach to assessing the built environment over a large geographic extent. In this paper, we contribute to the built environment literature by describing a tool used to assess the residential built environment at the tax parcel-level, as well as a methodology for summarizing the data into meaningful indices for linkages with health data. Methods A database containing residential built environment variables was constructed using the existing body of literature, as well as input from local community partners. During the summer of 2008, a team of trained assessors conducted an on-foot, curb-side assessment of approximately 17,000 tax parcels in Durham, North Carolina, evaluating the built environment on over 80 variables using handheld Global Positioning System (GPS devices. The exercise was repeated again in the summer of 2011 over a larger geographic area that included roughly 30,700 tax parcels; summary data presented here are from the 2008 assessment.

    Background A growing corpus of research focuses on assessing the quality of the local built environment and also examining the relationship between the built environment and health outcomes and indicators in communities. However, there is a lack of research presenting a highly resolved, systematic, and comprehensive spatial approach to assessing the built environment over a large geographic extent. In this paper, we contribute to the built environment literature by describing a tool used to assess the residential built environment at the tax parcel-level, as well as a methodology for summarizing the data into meaningful indices for linkages with health data. Methods A database containing residential built environment variables was constructed using the existing body of literature, as well as input from local community partners. During the summer of 2008, a team of trained assessors conducted an on-foot, curb-side assessment of approximately 17,000 tax parcels in Durham, North Carolina, evaluating the built environment on over 80 variables using handheld Global Positioning System (GPS) devices. The exercise was repeated again in the summer of 2011 over a larger geographic area that included roughly 30,700 tax parcels; summary data presented here are from the 2008 assessment. Results Built environment data were combined with Durham crime data and tax assessor data in order to construct seven built environment indices. These indices were aggregated to US Census blocks, as well as to primary adjacency communities (PACs) and secondary adjacency communities (SACs) which better described the larger neighborhood context experienced by local residents. Results were disseminated to community members, public health professionals, and government officials. Conclusions The assessment tool described is both easily-replicable and comprehensive in design. Furthermore, our construction of PACs and SACs introduces a novel concept to approximate varying scales of community and

    Monitoring on data streams is an efficient method of acquiring the characters of data stream. However the available resources for each data stream are limited, so the problem of how to use the limited resources to process infinite data stream is an open challenging problem. In this paper, we adopt the wavelet and sliding window methods to design a multi-resolution summarization data structure, the Multi-Resolution Summarization Tree (MRST) which can be updated incrementally with the incoming data and can support point queries, range queries, multi-point queries and keep the precision of queries. We use both synthetic data and real-world data to evaluate our algorithm. The results of experiment indicate that the efficiency of query and the adaptability of MRST have exceeded the current algorithm, at the same time the realizationof it is simpler than others.

  2. Circulation of core collection monographs in an academic medical library.

    Academic medical librarians responsible for monograph acquisition face a challenging task. From the plethora of medical monographs published each year, academic medical librarians must select those most useful to their patrons. Unfortunately, none of the selection tools available to medical librarians are specifically intended to assist academic librarians with medical monograph selection. The few short core collection lists that are available are intended for use in the small hospital or internal medicine department library. As these are the only selection tools available, however, many academic medical librarians spend considerable time reviewing these collection lists and place heavy emphasis on the acquisition of listed books. The study reported here was initiated to determine whether the circulation of listed books in an academic library justified the emphasis placed on the acquisition of these books. Circulation statistics for "listed" and "nonlisted" books in the hematology (WH) section of Indiana University School of Medicine's Ruth Lilly Medical Library were studied. The average circulation figures for listed books were nearly two times as high as the corresponding figures for the WH books in general. These data support the policies of those academic medical libraries that place a high priority on collection of listed books.

    Tuberculosis (TB) remains a highly prevalent and potentially severe disease. However, since 2002 the annual incidence has been decreasing both worldwide and in Spain, where the incidence varies widely between regions. The main objective of this study is to describe the experience of a monographic TB unit in a second level hospital. A descriptive study was carried out which included all cases of TB diagnosed in a monographic unit of a secondary hospital between 2003 and 2011. Demographic, clinical, epidemiological and microbiological data were recorded. We analyzed 500 TB cases and found an increasing annual incidence in all subgroups, including native and immigrant populations. Most cases (63.8%) were male, with a median age of 36 years (range 8 months-90 years). In total, 39.8% of patients were foreign born. Coinfection with human immunodeficiency virus was found in 11% of cases. The pulmonary form was most frequently diagnosed (63.8%). Overall mortality was 5.8% with no significant differences between groups (including foreign born and human immunodeficiency virus positive patients). Although TB incidence is globally decreasing, in our study we found an increasing number of cases in recent years in all subgroups, which can be explained by this being a monographic unit with an intensive contact tracing program.

  4. Monograph of Keçiören Municipality

    Full Text Available In Turkey, urban administration can be defined from a judicial perspective as the bundle of powers vested in municipalities. It is known that throughout republican history, municipalities, using these powers, have differentiated themselves via their own internal dynamics in parallel to the evolution of public policy and changes in legislation. Yet, it is obvious that there are important gaps in understanding this differentiation taking into consideration the structural conditions of individual municipalities. In particular, in order to thoroughly understand municipalities, it is important to consider periodical pictures of how each municipality has been affected by waves of decentralization and centralization experienced over the last thirty years. In this respect, this monograph, using the same monographic approach developed for the Çankaya Municipality, provides a picture of the existing situation of Ankara’s Keçiören Municipality and presents related problems and potential. This monograph, based on qualitative and quantitative research, presents a holistic evaluation of Keçiören Municipality in terms of its external environment, provision of services, decision-making processes, use of technology and communications.

  5. Onboard Algorithms for Data Prioritization and Summarization of Aerial Imagery

    Many current and future NASA missions are capable of collecting enormous amounts of data, of which only a small portion can be transmitted to Earth. Communications are limited due to distance, visibility constraints, and competing mission downlinks. Long missions and high-resolution, multispectral imaging devices easily produce data exceeding the available bandwidth. To address this situation computationally efficient algorithms were developed for analyzing science imagery onboard the spacecraft. These algorithms autonomously cluster the data into classes of similar imagery, enabling selective downlink of representatives of each class, and a map classifying the terrain imaged rather than the full dataset, reducing the volume of the downlinked data. A range of approaches was examined, including k-means clustering using image features based on color, texture, temporal, and spatial arrangement

  6. Summarizing the evidence on the international trade in illegal wildlife.

    2010-08-01

    The global trade in illegal wildlife is a multi-billion dollar industry that threatens biodiversity and acts as a potential avenue for invasive species and disease spread. Despite the broad-sweeping implications of illegal wildlife sales, scientists have yet to describe the scope and scale of the trade. Here, we provide the most thorough and current description of the illegal wildlife trade using 12 years of seizure records compiled by TRAFFIC, the wildlife trade monitoring network. These records comprise 967 seizures including massive quantities of ivory, tiger skins, live reptiles, and other endangered wildlife and wildlife products. Most seizures originate in Southeast Asia, a recently identified hotspot for future emerging infectious diseases. To date, regulation and enforcement have been insufficient to effectively control the global trade in illegal wildlife at national and international scales. Effective control will require a multi-pronged approach including community-scale education and empowering local people to value wildlife, coordinated international regulation, and a greater allocation of national resources to on-the-ground enforcement.

    2010-01-01

    Practicing physicians have limited time for consulting medical knowledge and records. We have previously shown that using icons instead of text to present drug monographs may allow contraindications and adverse effects to be identified more rapidly and more accurately. These findings were based on the use of an iconic language designed for drug knowledge, providing icons for many medical concepts, including diseases, antecedents, drug classes and tests. In this paper, we describe a new project aimed at extending this iconic language, and exploring the possible applications of these icons in medicine. Based on evaluators' comments, focus groups of physicians and opinions of academic, industrial and associative partners, we propose iconic applications related to patient records, for example summarizing patient conditions, searching for specific clinical documents and helping to code structured data. Other applications involve the presentation of clinical practice guidelines and improving the interface of medical search engines. These new applications could use the same iconic language that was designed for drug knowledge, with a few additional items that respect the logic of the language.

  18. [The HMPC monograph on Hypericum: Background, development, contents].

    Science.gov (United States)

    Länger, Reinhard

    2010-12-01

    The adoption of the EU community monograph on Hypericum constitutes a milestone in the process of harmonisation of herbal medicinal products within the European Community. The assessment of the published clinical data revealed that for two types of extracts the evidence of the efficacy in mild to moderate depressive episodes compared to placebo or standard medication was found to be acceptable. Additionally, a sufficient efficacy in relapse prophylaxis could be demonstrated for these two herbal preparations. For some other dry extracts, the efficacy in the short-term treatment of symptoms in mild depressive disorders was found to be substantiated. Short-term treatment with preparations containing low amounts of hyperforin did not increase cytochrome P450 enzyme activity. Therefore the oral administration of traditional herbal preparations is restricted to two weeks. In the case that an applicant demonstrates that the daily intake of hyperforin is below 1 mg the warnings on interactions may be omitted in traditional herbal medicinal products. Additionally the cutaneous administration of traditional liquid herbal preparations for the traditional use in symptomatic treatment of minor inflammations of the skin and as an aid in healing minor wounds was included in the monograph.

  19. Revisiting an open access monograph experiment: measuring citations and tweets 5 years later.

    Snijder, Ronald

    2016-01-01

    An experiment run in 2009 could not assess whether making monographs available in open access enhanced scholarly impact. This paper revisits the experiment, drawing on additional citation data and tweets. It attempts to answer the following research question: does open access have a positive influence on the number of citations and tweets a monograph receives, taking into account the influence of scholarly field and language? The correlation between monograph citations and tweets is also investigated. The number of citations and tweets measured in 2014 reveal a slight open access advantage, but the influence of language or subject should also be taken into account. However, Twitter usage and citation behaviour hardly overlap.

    Full Text Available Abstract Background Each day, millions of health consumers seek drug-related information on the Web. Despite some efforts in linking related resources, drug information is largely scattered in a wide variety of websites of different quality and credibility. Methods As a step toward providing users with integrated access to multiple trustworthy drug resources, we aim to develop a method capable of identifying drug's dosage form information in addition to drug name recognition. We developed rules and patterns for identifying dosage forms from different sections of full-text drug monographs, and subsequently normalized them to standardized RxNorm dosage forms. Results Our method represents a significant improvement compared with a baseline lookup approach, achieving overall macro-averaged Precision of 80%, Recall of 98%, and F-Measure of 85%. Conclusions We successfully developed an automatic approach for drug dosage form identification, which is critical for building links between different drug-related resources.

    1993-01-01

    With deforestation in the Asia-Pacific region progressing at the rate of 4.4 million ha per year, many countries have adopted plantation forestry using fast-growing species as a way to sustain the commercial supply of tree products and reduce pressure on natural forests. Acacia mangium (A. mangium) is playing a large role in this development, especially in Indonesia and Malaysia, due to its versatility and its ability to recapture grasslands dominated by the noxious weed, Imperata cylindrica. This monograph consolidates information on A. mangium from published literature, unpublished reports and studies, and observations from those familiar with the species. Priorities for future research are included in each chapter and in the final summary.

    Inter-laboratory verification of European pharmacopoeia (EP) monograph on derivative spectrophotometry (DS) method and its application for chitosan hydrochloride was carried out on two generation of instruments (earlier GBC Cintra 20 and current technology TS Evolution 300). Instruments operate with different versions of Savitzky-Golay algorithm and modes of generating digital derivative spectra. For resolution power parameter, defined as the amplitude ratio A/B in DS method EP monograph, comparable results were obtained only with algorithm's parameters smoothing points (SP) 7 and the 2nd degree polynomial and those provided corresponding data with other two modes on TS Evolution 300 Medium digital indirect and Medium digital direct. Using quoted algorithm's parameters, the differences in percentages between the amplitude ratio A/B averages, were within accepted criteria (±3%) for assay of drug product for method transfer. The deviation of 1.76% for the degree of deacetylation assessment of chitosan hydrochloride, determined on two instruments, (amplitude (1)D202; the 2nd degree polynomial and SP 9 in Savitzky-Golay algorithm), was acceptable, since it was within allowed criteria (±2%) for assay deviation of drug substance, for method transfer in pharmaceutical analyses.

    Product monographs (also known by terms such as Summary of Product Characteristics and Highlights of Prescribing Information, depending on the jurisdiction) provide essential information to ensure the safe and effective use of a drug. Medical practitioners often rely on these monographs for guidance on matters related to pharmacokinetics as well as indications, contraindications, clinical pharmacology, and adverse reactions. The clinical and scientific information found within these documents, forming the basis for decision making, are presumed to be derived from well-designed studies. The objective of this review is to examine the source and validity of the pharmacokinetic data used in establishing the half-lives and times to steady-state reported in the product monographs of second-generation long-acting injectable antipsychotics. Thus, we have critically evaluated the clinical trials from which the pharmacokinetic parameters listed in the product monographs were determined. In many cases, the pharmacokinetic information presented in product monographs is of limited use to clinicians wishing to optimize the effectiveness and tolerability of second-generation long-acting injectable antipsychotics. Under such circumstances, off-label prescribing practices may actually produce better clinical outcomes than if decisions were made based on the product monographs alone.

  5. Three Evidence Based Methods to Compensate for a Lack of Subject Background when Ordering Chemistry Monographs

    2008-09-01

    Full Text Available Objective – The aim of this article is to present evidence based methods for the selection of chemistry monographs, particularly for librarians lacking a background in chemistry. These methods will be described in detail, their practical application illustrated, and their efficacy tested by analyzing circulation data.Methods – Two hundred and ninety-five chemistry monographs were selected between 2005 and 2007 using rigorously-applied evidence based methods involving the Library's integrated library system (ILS, Google, and SciFinder Scholar. The average circulation rate of this group of monographs was compared to the average circulation rate of 254 chemistry monographs selected between 2002 and 2004 when the methods were not used or were in an incomplete state of development.Results – Circulations/month were on average 9% greater in the cohort of monographs selected with the rigorously-applied evidence based methods. Further statistical analysis, however, finds that this result can not be attributed to the different application of these methods. Conclusion – The methods discussed in this article appear to provide an evidence base for the selection of chemistry monographs, but their application does not change circulation rates in a statistically significant way. Further research is needed to determine if this lack of statistical significance is real or a product of the organic development and application of these methods over time, making definitive comparisons difficult.

  7. NTP-CERHR monograph on Soy Infant Formula.

    Science.gov (United States)

    2010-09-01

    Soy infant formula contains soy protein isolates and is fed to infants as a supplement to or replacement for human milk or cow milk. Soy protein isolates contains estrogenic isoflavones ("phytoestrogens") that occur naturally in some legumes, especially soybeans. Phytoestrogens are non-steroidal, estrogenic compounds. In plants, nearly all phytoestrogens are bound to sugar molecules and these phytoestrogen-sugar complexes are not generally considered hormonally active. Phytoestrogens are found in many food products in addition to soy infant formula, especially soy-based foods such as tofu, soy milk, and in some over-the-counter dietary supplements. Soy infant formula was selected for evaluation by the National Toxicology Program (NTP) because of the: (1)availability of large number of developmental toxicity studies in laboratory animals exposed to the isoflavones found in soy infant formula (namely, genistein) or other soy products, as well as a number of studies on human infants fed soy infant formula, (2)the availability of information on exposures in infants fed soy infant formula, and (3)public concern for effects on infant or child development. The NTP evaluation was conducted through its Center for the Evaluation of Risks to Human Reproduction (CERHR) and completed in September 2010. The results of this soy infant formula evaluation are published in an NTP Monograph. This document contains the NTP Brief on Soy Infant Formula, which presents NTP's opinion on the potential for exposure to soy infant formula to cause adverse developmental effects in humans. The NTP Monograph also contains an expert panel report prepared to assist the NTP in reaching conclusions on soy infant formula. The NTP concluded there is minimal concern for adverse effects on development in infants who consume soy infant formula. This level of concern represents a "2" on the five-level scale of concern used by the NTP that ranges from negligible concern ("1") to serious concern ("5"). This

    Redelings, Benjamin D.

    2017-01-01

    We present a new supertree method that enables rapid estimation of a summary tree on the scale of millions of leaves. This supertree method summarizes a collection of input phylogenies and an input taxonomy. We introduce formal goals and criteria for such a supertree to satisfy in order to transparently and justifiably represent the input trees. In addition to producing a supertree, our method computes annotations that describe which grouping in the input trees support and conflict with each group in the supertree. We compare our supertree construction method to a previously published supertree construction method by assessing their performance on input trees used to construct the Open Tree of Life version 4, and find that our method increases the number of displayed input splits from 35,518 to 39,639 and decreases the number of conflicting input splits from 2,760 to 1,357. The new supertree method also improves on the previous supertree construction method in that it produces no unsupported branches and avoids unnecessary polytomies. This pipeline is currently used by the Open Tree of Life project to produce all of the versions of project’s “synthetic tree” starting at version 5. This software pipeline is called “propinquity”. It relies heavily on “otcetera”—a set of C++ tools to perform most of the steps of the pipeline. All of the components are free software and are available on GitHub. PMID:28265520

  10. A classification and summarization method for analysis of research activities in an academic faculty

    Directory of Open Access Journals (Sweden)

    Eduardo Rocha Loures

    Full Text Available Abstract Nowadays, more and more scientific research activities are carried out in different laboratories and universities, which not only play an important role in the development of science and technology, but also show a significant inference on education. The improvement of the research capability of an academic faculty can directly impact the quality of education, bring innovations to Industrial Engineering curriculum proposals, and guarantee the subjects are up to date. The investigation of the existing issues in the current research activities is usually considered as the primary and challenging step. As the output of research activities, academic articles are often considered as a kind of evidence-based resources for the investigation. Despite some methodological efforts have been made by existing article review methods, less attention has been paid to discover the implicit academic relationships among the academic staffs and to investigate their research expertise. The objective of this study is to address this existing drawback through the proposition of an Academic Information Classification and Summarization method. A case study is carried out in the Industrial and System Engineering Graduate Program (PPGEPS, PUCPR, Brazil. The result not only highlights the advantages that can be obtained from this proposition from the education perspective related to Industrial Engineering, but also can be used as evidence to balance and compare an academic staff’s research expertise and his/her teaching disciplines.

The new supertree method also improves on the previous supertree construction method in that it produces no unsupported branches and avoids unnecessary polytomies. This pipeline is currently used by the Open Tree of Life project to produce all of the versions of project’s “synthetic tree” starting at version 5. This software pipeline is called “propinquity”. It relies heavily on “otcetera”—a set of C++ tools to perform most of the steps of the pipeline. All of the components are free software and are available on GitHub.

    The amount of information for clinicians and clinical researchers is growing exponentially. Text summarization reduces information as an attempt to enable users to find and understand relevant source texts more quickly and effortlessly. In recent years, substantial research has been conducted to develop and evaluate various summarization techniques in the biomedical domain. The goal of this study was to systematically review recent published research on summarization of textual documents in the biomedical domain. MEDLINE (2000 to October 2013), IEEE Digital Library, and the ACM digital library were searched. Investigators independently screened and abstracted studies that examined text summarization techniques in the biomedical domain. Information is derived from selected articles on five dimensions: input, purpose, output, method and evaluation. Of 10,786 studies retrieved, 34 (0.3%) met the inclusion criteria. Natural language processing (17; 50%) and a hybrid technique comprising of statistical, Natural language processing and machine learning (15; 44%) were the most common summarization approaches. Most studies (28; 82%) conducted an intrinsic evaluation. This is the first systematic review of text summarization in the biomedical domain. The study identified research gaps and provides recommendations for guiding future research on biomedical text summarization. Recent research has focused on a hybrid technique comprising statistical, language processing and machine learning techniques. Further research is needed on the application and evaluation of text summarization in real research or patient care settings. Copyright © 2014 Elsevier Inc. All rights reserved.

    2012-12-01

    Approximately 5,000 cases of chronic myelogenous leukemia (CML) are diagnosed each year in the United States. The introduction of tyrosine kinase inhibitors (TKIs) has dramatically improved survival time for many CML patients. Current first-line treatment options include imatinib and the second-generation agents nilotinib and dasatinib. Second- and third-line agents include nilotinib, dasatinib, bosutinib, and the new agent ponatinib. Despite the effectiveness of TKIs, some patients develop resistance or intolerance to these agents. A number of mutations of the BCR-ABL gene have been identified and are associated with TKI resistance. Patients may benefit from switching to a second-line TKI, undergoing hematopoietic stem cell transplant, or receiving newly emerging agents. Although early response is associated with improved patient outcome, clinicians lack tests that can determine which patients will benefit from which therapies. To ensure adequate response, patients should be monitored by both polymerase chain reaction and cytogenetic analysis of the bone marrow. This roundtable monograph reviews key unmet needs in patients with CML related to disease management and treatment options.

    Historically, the treatment of metastatic castration-resistant prostate cancer (CRPC) has been limited to chemotherapeutic regimens that did not improve patient survival. In 2004, clinical studies began to demonstrate significant improvements in patient outcomes, including overall survival, with docetaxel versus mitoxantrone chemotherapy. Since these pivotal trials, the combination of docetaxel plus prednisone has become a standard of care for patients with metastatic CRPC. However, the limited survival benefit achieved with this regimen prompted several investigations into the development of alternative therapeutic options. Recent advances have now led to an unprecedented number of new drug approvals within the past year, providing many new treatment options for patients with metastatic CRPC. Sipuleucel-T, considered a new paradigm in cancer treatment, is the first such immunotherapeutic agent approved by the US Food and Drug Administration. Other successes include abiraterone acetate, the first androgen biosynthesis inhibitor, and cabazitaxel, a novel microtubule inhibitor, both of which have demonstrated improved survival following docetaxel failure. The bone-targeting agent denosumab, also recently approved in this setting, offers these patients significant improvement in the prevention of skeletal-related events. The data supporting the approval of each of these agents are described in this monograph, as are current approaches in the treatment of metastatic CRPC and ongoing clinical trials of novel treatments and strategies. The experts also discuss several of the issues regarding the introduction of these novel agents into clinical practice for metastatic CRPC patients.

    With the rapid development of the Internet, multi documents summarization is becoming a very hot research topic. In order to generate a summarization that can effectively characterize the original information from documents, this paper proposes a multi documents summarization approach based on the physical features and logical structure of the document set. This method firstly clusterssimilar sentences into several Logical Topics (LTs), and then orders these topics according to their physical features of multi documents. After that, sentences used for the summarization are extracted from these LTs, and finally the summarization is generated via certain sorting algorithms. Our experiments show that the information coverage rate of our method is 8.83% higher than those methods based solely on logical structures, and 14.31% higher than Top-N method.

  1. Studying the correlation between different word sense disambiguation methods and summarization effectiveness in biomedical texts

    Full Text Available Abstract Background Word sense disambiguation (WSD attempts to solve lexical ambiguities by identifying the correct meaning of a word based on its context. WSD has been demonstrated to be an important step in knowledge-based approaches to automatic summarization. However, the correlation between the accuracy of the WSD methods and the summarization performance has never been studied. Results We present three existing knowledge-based WSD approaches and a graph-based summarizer. Both the WSD approaches and the summarizer employ the Unified Medical Language System (UMLS Metathesaurus as the knowledge source. We first evaluate WSD directly, by comparing the prediction of the WSD methods to two reference sets: the NLM WSD dataset and the MSH WSD collection. We next apply the different WSD methods as part of the summarizer, to map documents onto concepts in the UMLS Metathesaurus, and evaluate the summaries that are generated. The results obtained by the different methods in both evaluations are studied and compared. Conclusions It has been found that the use of WSD techniques has a positive impact on the results of our graph-based summarizer, and that, when both the WSD and summarization tasks are assessed over large and homogeneous evaluation collections, there exists a correlation between the overall results of the WSD and summarization tasks. Furthermore, the best WSD algorithm in the first task tends to be also the best one in the second. However, we also found that the improvement achieved by the summarizer is not directly correlated with the WSD performance. The most likely reason is that the errors in disambiguation are not equally important but depend on the relative salience of the different concepts in the document to be summarized.

  2. Summarization and Matching of Density-Based Clusters in Streaming Environments

    2011-01-01

    Density-based cluster mining is known to serve a broad range of applications ranging from stock trade analysis to moving object monitoring. Although methods for efficient extraction of density-based clusters have been studied in the literature, the problem of summarizing and matching of such clusters with arbitrary shapes and complex cluster structures remains unsolved. Therefore, the goal of our work is to extend the state-of-art of density-based cluster mining in streams from cluster extraction only to now also support analysis and management of the extracted clusters. Our work solves three major technical challenges. First, we propose a novel multi-resolution cluster summarization method, called Skeletal Grid Summarization (SGS), which captures the key features of density-based clusters, covering both their external shape and internal cluster structures. Second, in order to summarize the extracted clusters in real-time, we present an integrated computation strategy C-SGS, which piggybacks the generation of...

  4. A Unified Framework for Event Summarization and Rare Event Detection from Multiple Views.

    Science.gov (United States)

    Kwon, Junseok; Lee, Kyoung Mu

    2015-09-01

    A novel approach for event summarization and rare event detection is proposed. Unlike conventional methods that deal with event summarization and rare event detection independently, our method solves them in a single framework by transforming them into a graph editing problem. In our approach, a video is represented by a graph, each node of which indicates an event obtained by segmenting the video spatially and temporally. The edges between nodes describe the relationship between events. Based on the degree of relations, edges have different weights. After learning the graph structure, our method finds subgraphs that represent event summarization and rare events in the video by editing the graph, that is, merging its subgraphs or pruning its edges. The graph is edited to minimize a predefined energy model with the Markov Chain Monte Carlo (MCMC) method. The energy model consists of several parameters that represent the causality, frequency, and significance of events. We design a specific energy model that uses these parameters to satisfy each objective of event summarization and rare event detection. The proposed method is extended to obtain event summarization and rare event detection results across multiple videos captured from multiple views. For this purpose, the proposed method independently learns and edits each graph of individual videos for event summarization or rare event detection. Then, the method matches the extracted multiple graphs to each other, and constructs a single composite graph that represents event summarization or rare events from multiple views. Experimental results show that the proposed approach accurately summarizes multiple videos in a fully unsupervised manner. Moreover, the experiments demonstrate that the approach is advantageous in detecting rare transition of events.

  5. Using Confidence Interval to Summarize the Evaluating Results of DSM Systems

    2000-01-01

    Distributed Shared Memory (DSM) systems have gained popular acceptance by combining the scalability and low cost of distributed system with the ease of use of single address space. Many new hardware DSM and software DSM systems have been proposed in recent years. In general, benchmarking is widely used to demonstrate the performance advantages of new systems. However, the common method used to summarize the measured results is the arithmetic mean of ratios,which is incorrect in some cases. Furthermore, many published papers list a lot of data only, and do not summarize them effectively, which confuse users greatly. In fact, many users want to get a single number as conclusion, which is not provided in old summarizing techniques. Therefore, a new data-summarizing technique based on confidence interval is proposed in this paper. The new technique includes two data-summarizing methods: (1) paired confidence interval method; (2) unpaired confidence interval method. With this new technique, it is concluded that at some confidence one system is better than others. Four examples are shown to demonstrate the advantages of this new technique. Furthermore, with the help of confidence level,it is proposed to standardize the benchmarks used for evaluating DSM systems so that a convincing result can be got. In addition, the new summarizing technique fits not only for evaluating DSM systems, but also for evaluating other systems, such as memory system and communication systems.

    1988-09-01

    The purpose of this study was to compare the summary writing skills of hearing-impaired and normally hearing college students. Summarization was defined in terms of the following measures: deletion of trivial text information, inclusion of most important ideas, selection of topic sentences, creation of topic statements, and integration of information within and among several paragraphs. Inclusion of opinionated, incorrect, and uninterpretable information was measured also. Thirty hearing-impaired and 30 normally hearing students read and summarized two expository science passages that were controlled for the number of topic (main idea) sentences and that had been rated previously for the importance of "idea units." Students' factual comprehension also was assessed. Hearing-impaired and normally hearing students exhibited a similar pattern of use among several measured summarization strategies, except for the inclusion of opinions or comments in their summaries. Hearing-impaired students were not as sensitive as normally hearing students to importance of ideas and used the following summarization strategies significantly less often: inclusion of important ideas, selection of topic sentences, creation of topic statements, and integration of ideas within and among paragraphs. The results indicated that hearing-impaired college students have basic summarization skills but do not apply summarization strategies as effectively as normally hearing students.

Diagnostic refinement is a necessary step in this direction, as is use of sophisticated technology to aid the process.And yet, we know that psychiatry, its practitioners, and its patients, do not function in a vacuum. They interact with, and are influenced by, a wide range of complex, interlinked, social and interpersonal forces.These forces are often generated by people not directly connected with the medical speciality of psychiatry. They are the policy-planners, governments, political leaders, activists, social thinkers, NGOs, mass media, enlightened public opinion etc. They have marked influence on social thought and action, policy, funding and research. They influence people and societies often in more significant ways than the medical speciality of psychiatry considers healthy for society.We may continue to function in a vacuum and wait for wisdom to dawn. Or, we may establish a dialogue with them and work for wisdom for happen.The second option seems the more productive one.No doubt, there are some psychiatrists comfortable with the biological label. There are others comfortable with the social one. Both these are needed, for they help to further robust enquiry in their respective fields. But what we also probably need is an integration, a synthesis of the mass of evidence that these two fields have produced. The inevitable conclusions drawn at our present state of knowledge based on such integration will give rise to pointers for further research as well as guidelines for policy-planners. Moreover, it will result in an awakened public opinion empowered with knowledge and evidence, its actions enlightened, and unlikely to be swayed or manipulated by unscrupulous forces.The Mens Sana Monographs are meant to further attempts at such a Fourth

    To describe the development and assessment of monographs as an assignment to incorporate evidence-based medicine (EBM) and pharmacoeconomic principles into a third-year pharmacoeconomic course. Eight newly FDA-approved drugs were assigned to 16 teams of students, where each drug was assigned to 2 teams. Teams had to research their drug, write a professional monograph, deliver an oral presentation, and answer questions posed by faculty judges. One team was asked to present evidence for inclusion of the drug into a formulary, while another team presented evidence against inclusion. The teams' average score on the written report was 99.1%; on the oral presentation, 92.5%, and on the online quiz given at the end of the presentations, 77%. Monographs are a successful method of incorporating and integrating learning across different concepts, as well as increasing relevance of pharmacoeconomics in the PharmD curriculum.

  13. Theory and implementation of summarization: Improving sensor interpretation for spacecraft operations

    Science.gov (United States)

    Swartwout, Michael Alden

    New paradigms in space missions require radical changes in spacecraft operations. In the past, operations were insulated from competitive pressures of cost, quality and time by system infrastructures, technological limitations and historical precedent. However, modern demands now require that operations meet competitive performance goals. One target for improvement is the telemetry downlink, where significant resources are invested to acquire thousands of measurements for human interpretation. This cost-intensive method is used because conventional operations are not based on formal methodologies but on experiential reasoning and incrementally adapted procedures. Therefore, to improve the telemetry downlink it is first necessary to invent a rational framework for discussing operations. This research explores operations as a feedback control problem, develops the conceptual basis for the use of spacecraft telemetry, and presents a method to improve performance. The method is called summarization, a process to make vehicle data more useful to operators. Summarization enables rational trades for telemetry downlink by defining and quantitatively ranking these elements: all operational decisions, the knowledge needed to inform each decision, and all possible sensor mappings to acquire that knowledge. Summarization methods were implemented for the Sapphire microsatellite; conceptual health management and system models were developed and a degree-of-observability metric was defined. An automated tool was created to generate summarization methods from these models. Methods generated using a Sapphire model were compared against the conventional operations plan. Summarization was shown to identify the key decisions and isolate the most appropriate sensors. Secondly, a form of summarization called beacon monitoring was experimentally verified. Beacon monitoring automates the anomaly detection and notification tasks and migrates these responsibilities to the space segment. A

    2012-01-01

    Full Text Available The technology of automatic document summarization is maturing and may provide a solution to the information overload problem. Nowadays, document summarization plays an important role in information retrieval. With a large volume of documents, presenting the user with a summary of each document greatly facilitates the task of finding the desired documents. Document summarization is a process of automatically creating a compressed version of a given document that provides useful information to users, and multi-document summarization is to produce a summary delivering the majority of information content from a set of documents about an explicit or implicit main topic. According to the input text, in this paper we use the knowledge base of Wikipedia and the words of the main text to create independent graphs. We will then determine the important of graphs. Then we are specified importance of graph and sentences that have topics with high importance. Finally, we extract sentences with high importance. The experimental results on an open benchmark datasets from DUC01 and DUC02 show that our proposed approach can improve the performance compared to state-of-the-art summarization approaches

    Anderson, Derek; Luke, Robert H; Keller, James M; Skubic, Marjorie; Rantz, Marilyn; Aud, Myra

    2009-01-01

    In this paper, we present a method for recognizing human activity from linguistic summarizations of temporal fuzzy inference curves representing the states of a three-dimensional object called voxel person. A hierarchy of fuzzy logic is used, where the output from each level is summarized and fed into the next level. We present a two level model for fall detection. The first level infers the states of the person at each image. The second level operates on linguistic summarizations of voxel person's states and inference regarding activity is performed. The rules used for fall detection were designed under the supervision of nurses to ensure that they reflect the manner in which elders perform these activities. The proposed framework is extremely flexible. Rules can be modified, added, or removed, allowing for per-resident customization based on knowledge about their cognitive and physical ability.

See bisphenol A under "CERHR Chemicals" on the homepage or go directly to http://cerhr.niehs. nih.gov/chemicals/bisphenol/bisphenol.html). The NTP reached the following conclusions on the possible effects of exposure to bisphenol A on human development and reproduction. Note that the possible levels of concern, from lowest to highest, are negligible concern, minimal concern, some concern, concern, and serious concern. The NTP has some concern for effects on the brain, behavior, and prostate gland in fetuses, infants, and children at current human exposures to bisphenol A. The NTP has minimal concern for effects on the mammary gland and an earlier age for puberty for females in fetuses, infants, and children at current human exposures to bisphenol A. The NTP has negligible concern that exposure of pregnant women to bisphenol A will result in fetal or neonatal mortality, birth defects, or reduced birth weight and growth in their offspring. The NTP has negligible concern that exposure to bisphenol A will cause reproductive effects in non-occupationally exposed adults and minimal concern for workers exposed to higher levels in occupational settings. NTP will transmit the NTP-CERHR Monograph on Bisphenol A to federal and state agencies, interested parties, and the public and make it available in electronic PDF format on the CERHR web site (http://cerhr.niehs.nih.gov) and in printed text or CD from CERHR.

However, for IE to be practically applicable, adaptability of a system is crucial, considering extremely diverse demands in biomedical IE application. One should be able to extract a set of hidden patterns from these biomedical datasets at low cost. Approach: In this study, a new method is proposed, called Bio-medical Data Aggregation for Relational Attributes (BioDARA, for automatic structuring information extraction for biomedical datasets. BioDARA summarizes biomedical data stored in multiple tables in order to facilitate data modeling efforts in a multi-relational setting. BioDARA has the advantages or capabilities to transform biomedical data stored in multiple tables or databases into a Vector Space model, summarize biomedical data using the Information Retrieval theory and finally extract frequent patterns that describe the characteristics of these biomedical datasets. Results: the results show that data summarization performed by DARA, can be beneficial in summarizing biomedical datasets in a complex multi-relational environment, in which biomedical datasets are stored in a multi-level of one-to-many relationships and also in the case of datasets stored in more than one one-to-many relationships with non-target tables. Conclusion: This study concludes that data summarization performed by BioDARA, can be beneficial in summarizing biomedical datasets in a complex multi-relational environment, in which biomedical datasets are stored in a multi-level of one-to-many relationships.

  20. Research on multi-document summarization based on latent semantic indexing

    Institute of Scientific and Technical Information of China (English)

    QIN Bing; LIU Ting; ZHANG Yu; LI Sheng

    2005-01-01

    A multi-document summarization method based on Latent Semantic Indexing (LSI) is proposed. The method combines several reports on the same issue into a matrix of terms and sentences, and uses a Singular Value Decomposition (SVD) to reduce the dimension of the matrix and extract features, and then the sentence similarity is computed. The sentences are clustered according to similarity of sentences. The centroid sentences are selected from each class. Finally, the selected sentences are ordered to generate the summarization. The evaluation and results are presented, which prove that the proposed methods are efficient.

    Full Text Available Abstract Background Abundant information about gene products is stored in online searchable databases such as annotation or literature. To efficiently obtain and digest such information, there is a pressing need for automated information-summarization and functional-similarity clustering of genes. Results We have developed a novel method for semantic measurement of annotation and integrated it with a biomedical literature summarization system to establish a platform, GeneLibrarian, to provide users well-organized information about any specific group of genes (e.g. one cluster of genes from a microarray chip they might be interested in. The GeneLibrarian generates a summarized viewgraph of candidate genes for a user based on his/her preference and delivers the desired background information effectively to the user. The summarization technique involves optimizing the text mining algorithm and Gene Ontology-based clustering method to enable the discovery of gene relations. Conclusion GeneLibrarian is a Java-based web application that automates the process of retrieving critical information from the literature and expanding the number of potential genes for further analysis. This study concentrates on providing well organized information to users and we believe that will be useful in their researches. GeneLibrarian is available on http://gen.csie.ncku.edu.tw/GeneLibrarian/

  2. Man-made mineral (vitreous) fibres: evaluations of cancer hazards by the IARC Monographs Programme.

    Science.gov (United States)

    Baan, Robert A; Grosse, Yann

    2004-09-03

    Man-made vitreous (glass-like) fibres are non-crystalline, fibrous inorganic substances (silicates) made primarily from rock, slag, glass or other processed minerals. These materials, also called man-made mineral fibres, include glass fibres (used in glass wool and continuous glass filament), rock or stone wool, slag wool and refractory ceramic fibres. They are widely used for thermal and acoustical insulation and to a lesser extent for other purposes. These products are potentially hazardous to human health because they release airborne respirable fibres during their production, use and removal. Man-made mineral fibres and man-made vitreous fibres have been the subject of reviews by IARC Monographs Working Groups in 1987 and 2001, respectively, which resulted in evaluations of the carcinogenic hazard to humans from exposure to these materials. These reviews and evaluations have been published as Volumes 43 and 81 of the IARC Monographs series [IARC Monographs on the Evaluation of Carcinogenic Risks to Humans, vol. 43, Man-made Mineral Fibres and Radon (1988); IARC Monographs on the Evaluation of Carcinogenic Risks to Humans, vol. 81, Man-made Vitreous Fibres (2002)]. The re-evaluation in 2001 was undertaken because there have been substantial improvements in the quality of the epidemiological information available on the carcinogenicity to humans of glass fibres, continuous glass filament and rock/slag wool. The new evaluations have addressed the limitations of earlier cohort studies, particularly concerning the lack of adjustment with respect to concomitant risk factors such as smoking and other sources of occupational exposure. In addition, the evaluation of the evidence for carcinogenicity of glass fibres to experimental animals has been refined, by making a distinction between insulation glass wool and special-purpose glass fibres. The results of the evaluations in 1987 and 2001 are thus different in several aspects. In this paper, the reviews and evaluations

    Directory of Open Access Journals (Sweden)

    R.V.V Murali Krishna

    2012-05-01

    Full Text Available The developments in storage devices and computer networks have given the scope for the world to become a paperless community, for example Digital news paper systems and digital library systems. A paperless community is heavily dependent on information retrieval systems. Text summarization is an area that supports the cause of information retrieval systems by helping the users to get their needed information. This paper discusses on the relevance of using traditional stoplists for text summarization and the use of Statistical analysis for sentence scoring. A new methodology is proposed for implementing the stoplist concept and statistical analysis concept based on parts of speech tagging. A sentence scoring mechanism has been developed by combining the above methodologies with semantic analysis. This sentence scoring method has given good results when applied to find out the relation between natural language queries and the sentences in a document.

  5. Semisupervised Learning Based Opinion Summarization and Classification for Online Product Reviews

    Directory of Open Access Journals (Sweden)

    Mita K. Dalal

    2013-01-01

    Full Text Available The growth of E-commerce has led to the invention of several websites that market and sell products as well as allow users to post reviews. It is typical for an online buyer to refer to these reviews before making a buying decision. Hence, automatic summarization of users’ reviews has a great commercial significance. However, since the product reviews are written by nonexperts in an unstructured, natural language text, the task of summarizing them is challenging. This paper presents a semisupervised approach for mining online user reviews to generate comparative feature-based statistical summaries that can guide a user in making an online purchase. It includes various phases like preprocessing and feature extraction and pruning followed by feature-based opinion summarization and overall opinion sentiment classification. Empirical studies indicate that the approach used in the paper can identify opinionated sentences from blog reviews with a high average precision of 91% and can classify the polarity of the reviews with a good average accuracy of 86%.

  6. Evaluation of a gene information summarization system by users during the analysis process of microarray datasets.

    Yang, Jianji; Cohen, Aaron; Hersh, William

    2009-02-05

    Summarization of gene information in the literature has the potential to help genomics researchers translate basic research into clinical benefits. Gene expression microarrays have been used to study biomarkers for disease and discover novel types of therapeutics and the task of finding information in journal articles on sets of genes is common for translational researchers working with microarray data. However, manually searching and scanning the literature references returned from PubMed is a time-consuming task for scientists. We built and evaluated an automatic summarizer of information on genes studied in microarray experiments. The Gene Information Clustering and Summarization System (GICSS) is a system that integrates two related steps of the microarray data analysis process: functional gene clustering and gene information gathering. The system evaluation was conducted during the process of genomic researchers analyzing their own experimental microarray datasets. The clusters generated by GICSS were validated by scientists during their microarray analysis process. In addition, presenting sentences in the abstract provided significantly more important information to the users than just showing the title in the default PubMed format. The evaluation results suggest that GICSS can be useful for researchers in genomic area. In addition, the hybrid evaluation method, partway between intrinsic and extrinsic system evaluation, may enable researchers to gauge the true usefulness of the tool for the scientists in their natural analysis workflow and also elicit suggestions for future enhancements. GICSS can be accessed online at: http://ir.ohsu.edu/jianji/index.html.

  7. An Efficient Technique for Network Traffic Summarization using Multiview Clustering and Statistical Sampling

    Directory of Open Access Journals (Sweden)

    Mohiuddin Ahmed

    2015-07-01

    Full Text Available There is significant interest in the data mining and network management communities to efficiently analyse huge amounts of network traffic, given the amount of network traffic generated even in small networks. Summarization is a primary data mining task for generating a concise yet informative summary of the given data and it is a research challenge to create summary from network traffic data. Existing clustering based summarization techniques lack the ability to create a suitable summary for further data mining tasks such as anomaly detection and require the summary size as an external input. Additionally, for complex and high dimensional network traffic datasets, there is often no single clustering solution that explains the structure of the given data. In this paper, we investigate the use of multiview clustering to create a meaningful summary using original data instances from network traffic data in an efficient manner. We develop a mathematically sound approach to select the summary size using a sampling technique. We compare our proposed approach with regular clustering based summarization incorporating the summary size calculation method and random approach. We validate our proposed approach using the benchmark network traffic dataset and state-of-theart summary evaluation metrics.

There are eleven text features, i.e, sentence position (f1, positive keywords in sentence (f2, negative keywords in sentence (f3, sentence centrality (f4, sentence resemblance to the title (f5, sentence inclusion of name entity (f6, sentence inclusion of numerical data (f7, sentence relative length (f8, bushy path of the node (f9, summation of similarities for each node (f10, and latent semantic feature (f11. We investigate the effect of the first ten sentence features on the summarization task. Then, we use latent semantic feature to increase the accuracy. All feature score functions are used to train a genetic algorithm model to obtain a suitable combination of feature weights. Evaluation of text summarization uses F-measure. The F-measure directly related to the compression rate. The results showed that adding f11 increases the F-measure by 3.26% and 1.55% for compression ratio of 10% and 30%, respectively. On the other hand, it decreases the F-measure by 0.58% for compression ratio of 20%. Analysis of text feature weight showed that only using f2, f4, f5, and f11 can deliver a similar performance using all eleven features.

    In studies of environmental issues, the question of how to establish a productive interplay between science and policy is widely debated, especially in relation to climate change. The aim of this article is to advance this discussion and contribute to a better understanding of how science is summarized for policy purposes by bringing together two academic discussions that usually take place in parallel: the question of how to deal with formalization (structuring the procedures for assessing and summarizing research, e.g. by protocols) and separation (maintaining a boundary between science and policy in processes of synthesizing science for policy). Combining the two dimensions, we draw a diagram onto which different initiatives can be mapped. A high degree of formalization and separation are key components of the canonical image of scientific practice. Influential Science and Technology Studies analysts, however, are well known for their critiques of attempts at separation and formalization. Three examples that summarize research for policy purposes are presented and mapped onto the diagram: the Intergovernmental Panel on Climate Change, the European Union's Science for Environment Policy initiative, and the UK Committee on Climate Change. These examples bring out salient differences concerning how formalization and separation are dealt with. Discussing the space opened up by the diagram, as well as the limitations of the attraction to its endpoints, we argue that policy analyses, including much Science and Technology Studies work, are in need of a more nuanced understanding of the two crucial dimensions of formalization and separation. Accordingly, two analytical claims are presented, concerning trajectories, how organizations represented in the diagram move over time, and mismatches, how organizations fail to handle the two dimensions well in practice.

    Full Text Available Abstract Background Summarization of gene information in the literature has the potential to help genomics researchers translate basic research into clinical benefits. Gene expression microarrays have been used to study biomarkers for disease and discover novel types of therapeutics and the task of finding information in journal articles on sets of genes is common for translational researchers working with microarray data. However, manually searching and scanning the literature references returned from PubMed is a time-consuming task for scientists. We built and evaluated an automatic summarizer of information on genes studied in microarray experiments. The Gene Information Clustering and Summarization System (GICSS is a system that integrates two related steps of the microarray data analysis process: functional gene clustering and gene information gathering. The system evaluation was conducted during the process of genomic researchers analyzing their own experimental microarray datasets. Results The clusters generated by GICSS were validated by scientists during their microarray analysis process. In addition, presenting sentences in the abstract provided significantly more important information to the users than just showing the title in the default PubMed format. Conclusion The evaluation results suggest that GICSS can be useful for researchers in genomic area. In addition, the hybrid evaluation method, partway between intrinsic and extrinsic system evaluation, may enable researchers to gauge the true usefulness of the tool for the scientists in their natural analysis workflow and also elicit suggestions for future enhancements.

    Automatic Chinese text summarization for dialogue style is a relatively new research area. In this paper, Latent Semantic Analysis (LSA) is first used to extract semantic knowledge from a given document, all question paragraphs are identified,an automatic text segmentation approach analogous to TextTiling is exploited to improve the precision of correlating question paragraphs and answer paragraphs, and finally some "important" sentences are extracted from the generic content and the question-answer pairs to generate a complete summary. Experimental results showed that our approach is highly efficient and improves significantly the coherence of the summary while not compromising informativeness.

    The development of 3D technology provides more advantages in education sectors. In chemistry, the 3D technology makes chemistry objects look more tangible. This research developed a monograph titled “Augmented Chemistry: Hydrocarbon” as learning enrichment materials. The development model consisted of 5 steps, which were the adaptation of the ADDIE model. The 3D objects of chemistry were built using the computer applications of Chem Sketch, and Google Sketch Up with AR Plugin. The 3D objects were displayed by relevant markers on the texts of the monograph from which the visualizations of the 3D objects appeared when they were captured by digital camera of laptop or smartphone, and were possibly viewed with free-rotation. Not only were 3D chemistry objects included in the monograph, but also graphics, videos, audios, and animations, which facilitated more fun learning for readers of the monograph. After the reviews by the experts of subject matter, of media, of instruction, and by peers, the monograph was revised, and then rated by chemistry teachers. The analysis of the data showed that the monograph titled “Augmented Chemistry: Hydrocarbon” was in the criteria of very good for the enrichment materials of Chemistry learning.

    Extracting data from publication reports is a standard process in systematic review (SR) development. However, the data extraction process still relies too much on manual effort which is slow, costly, and subject to human error. In this study, we developed a text summarization system aimed at enhancing productivity and reducing errors in the traditional data extraction process. We developed a computer system that used machine learning and natural language processing approaches to automatically generate summaries of full-text scientific publications. The summaries at the sentence and fragment levels were evaluated in finding common clinical SR data elements such as sample size, group size, and PICO values. We compared the computer-generated summaries with human written summaries (title and abstract) in terms of the presence of necessary information for the data extraction as presented in the Cochrane review's study characteristics tables. At the sentence level, the computer-generated summaries covered more information than humans do for systematic reviews (recall 91.2% vs. 83.8%, plearning and natural language processing are promising approaches to the development of such an extractive summarization system.

    The Danish Government's long-term energy strategy follows up on the political agreement of 29 March 2004. The energy strategy is a coherent formulation of the Government's long-term energy policy. The pivotal point for the energy strategy is liberalized energy markets and market based tools for obtaining goals such as efficiency, security of supply and environment. The focus is increasingly on the substantial business potential within development of new and more efficient energy technology, in which Denmark takes up several globally strong positions. Furthermore, transportation energy consumption has been included directly in an energy strategy for the first time. At the same time as the energy strategy is presented, a summarizing background report from the Danish Energy Agency with facts, analyses and evaluations is published, as well as a report from energinet.dk that summarizes the system responsibilities' input to that part of the energy strategy that deals with power infrastructure.

  16. Heterogeneity image patch index and its application to consumer video summarization.

    Dang, Chinh T; Radha, Hayder

    2014-06-01

    Automatic video summarization is indispensable for fast browsing and efficient management of large video libraries. In this paper, we introduce an image feature that we refer to as heterogeneity image patch (HIP) index. The proposed HIP index provides a new entropy-based measure of the heterogeneity of patches within any picture. By evaluating this index for every frame in a video sequence, we generate a HIP curve for that sequence. We exploit the HIP curve in solving two categories of video summarization applications: key frame extraction and dynamic video skimming. Under the key frame extraction frame-work, a set of candidate key frames is selected from abundant video frames based on the HIP curve. Then, a proposed patch-based image dissimilarity measure is used to create affinity matrix of these candidates. Finally, a set of key frames is extracted from the affinity matrix using a min–max based algorithm. Under video skimming, we propose a method to measure the distance between a video and its skimmed representation. The video skimming problem is then mapped into an optimization framework and solved by minimizing a HIP-based distance for a set of extracted excerpts. The HIP framework is pixel-based and does not require semantic information or complex camera motion estimation. Our simulation results are based on experiments performed on consumer videos and are compared with state-of-the-art methods. It is shown that the HIP approach outperforms other leading methods, while maintaining low complexity.

  17. Automatic video summarization driven by a spatio-temporal attention model

    2008-02-01

    According to the literature, automatic video summarization techniques can be classified in two parts, following the output nature: "video skims", which are generated using portions of the original video and "key-frame sets", which correspond to the images, selected from the original video, having a significant semantic content. The difference between these two categories is reduced when we consider automatic procedures. Most of the published approaches are based on the image signal and use either pixel characterization or histogram techniques or image decomposition by blocks. However, few of them integrate properties of the Human Visual System (HVS). In this paper, we propose to extract keyframes for video summarization by studying the variations of salient information between two consecutive frames. For each frame, a saliency map is produced simulating the human visual attention by a bottom-up (signal-dependent) approach. This approach includes three parallel channels for processing three early visual features: intensity, color and temporal contrasts. For each channel, the variations of the salient information between two consecutive frames are computed. These outputs are then combined to produce the global saliency variation which determines the key-frames. Psychophysical experiments have been defined and conducted to analyze the relevance of the proposed key-frame extraction algorithm.

    This monograph is a companion to UNOAI Monograph 96-2, "The Image of Airport Security: An Annotated Bibliography," compiled in June 1996. The White House Commission on Aviation Safety and Security, headed by Vice President Al Gore, was formed as a result of the TWA Flight 800 crash in August 1996. The Commission's final report included 31 recommendations addressed toward aviation security. The recommendations were cause for security issues to be revisited in the media and by the aviation industry. These developments necessitated the need for an updated bibliography to review the resulting literature. Many of the articles were written in response to the recommendations made by the Gore Commission. "Aviation Security: An Annotated Bibliography of Responses to the Gore Commission" is the result of this need.

    2009-04-01

    Full Text Available This article attempts to provide an "X-ray image" of rural life through the inventory of certain research methods and techniques used in the study of Romanian rural communities. Sociological monographs, including the sociological rural atlas,were the epitome of Gustian sociology. The investigation of rural life focusing on certain key aspects - economic, political, and religious - simultaneously, can provide a more comprehensive perspective on the Romanian village than would be possible by considering each of these elements on its own. Hence, the monograph brings unity to past and present realities. The dynamic character of sociology, on which the Sociological School of Bucharest focused, can be applied nowadays as well. The sociologist is called forth now more than ever in order to interfere with social life. In this case, the methodological tool, that is the monograph, is very useful. Through the Social Atlas, the problems of rural communities can be anticipated and diagnosed and, as such, certain serious problems which take place in a social dimension can be averted. Hence, the Social Atlas project is very useful for research on rural life, as the maps capture the progress of social change.

    2006-10-01

    The extraction methods in selected monographs of the European and the Swiss Pharmacopoeia were compared to pressurized liquid extraction (PLE) with respect to the yield of constituents to be dosed in the quantitative assay for the respective herbal drugs. The study included five drugs, Belladonnae folium, Colae semen, Boldo folium, Tanaceti herba and Agni casti fructus. They were selected to cover different classes of compounds to be analyzed and different extraction methods to be used according to the monographs. Extraction protocols for PLE were optimized by varying the solvents and number of extraction cycles. In PLE, yields > 97 % of extractable analytes were typically achieved with two extraction cycles. For alkaloid-containing drugs, the addition of ammonia prior to extraction significantly increased the yield and reduced the number of extraction cycles required for exhaustive extraction. PLE was in all cases superior to the extraction protocol of the pharmacopoeia monographs (taken as 100 %), with differences ranging from 108 % in case of parthenolide in Tanaceti herba to 343 % in case of alkaloids in Boldo folium.

    2007-01-01

    In this paper we present a fresh look at the problem of summarizing evolving events from multiple sources. After a discussion concerning the nature of evolving events we introduce a distinction between linearly and non-linearly evolving events. We present then a general methodology for the automatic creation of summaries from evolving events. At its heart lie the notions of Synchronic and Diachronic cross-document Relations (SDRs), whose aim is the identification of similarities and differences between sources, from a synchronical and diachronical perspective. SDRs do not connect documents or textual elements found therein, but structures one might call messages. Applying this methodology will yield a set of messages and relations, SDRs, connecting them, that is a graph which we call grid. We will show how such a grid can be considered as the starting point of a Natural Language Generation System. The methodology is evaluated in two case-studies, one for linearly evolving events (descriptions of football matc...

  3. Towards Real-Time Summarization of Scheduled Events from Twitter Streams

    2012-01-01

    This paper explores the real-time summarization of scheduled events such as soccer games from torrential flows of Twitter streams. We propose and evaluate an approach that substantially shrinks the stream of tweets in real-time, and consists of two steps: (i) sub-event detection, which determines if something new has occurred, and (ii) tweet selection, which picks a representative tweet to describe each sub-event. We compare the summaries generated in three languages for all the soccer games in "Copa America 2011" to reference live reports offered by Yahoo! Sports journalists. We show that simple text analysis methods which do not involve external knowledge lead to summaries that cover 84% of the sub-events on average, and 100% of key types of sub-events (such as goals in soccer). Our approach should be straightforwardly applicable to other kinds of scheduled events such as other sports, award ceremonies, keynote talks, TV shows, etc.

    2012-01-01

    Query sensitive summarization aims at providing the users with the summary of the contents of single or multiple web pages based on the search query. This paper proposes a novel idea of generating a comparative summary from a set of URLs from the search result. User selects a set of web page links from the search result produced by search engine. Comparative summary of these selected web sites is generated. This method makes use of HTML DOM tree structure of these web pages. HTML documents are segmented into set of concept blocks. Sentence score of each concept block is computed with respect to the query and feature keywords. The important sentences from the concept blocks of different web pages are extracted to compose the comparative summary on the fly. This system reduces the time and effort required for the user to browse various web sites to compare the information. The comparative summary of the contents would help the users in quick decision making.

    Since 1957, evaluations of offsite impacts from each year of operation have been summarized in publicly available, annual environmental reports. These evaluations included estimates of potential radiation exposure to members of the public, either in terms of percentages of the then permissible limits or in terms of radiation dose. The estimated potential radiation doses to maximally exposed individuals from each year of Hanford operations are summarized in a series of tables and figures. The applicable standard for radiation dose to an individual for whom the maximum exposure was estimated is also shown. Although the estimates address potential radiation doses to the public from each year of operations at Hanford between 1957 and 1984, their sum will not produce an accurate estimate of doses accumulated over this time period. The estimates were the best evaluations available at the time to assess potential dose from the current year of operation as well as from any radionuclides still present in the environment from previous years of operation. There was a constant striving for improved evaluation of the potential radiation doses received by members of the public, and as a result the methods and assumptions used to estimate doses were periodically modified to add new pathways of exposure and to increase the accuracy of the dose calculations. Three conclusions were reached from this review: radiation doses reported for the years 1957 through 1984 for the maximum individual did not exceed the applicable dose standards; radiation doses reported over the past 27 years are not additive because of the changing and inconsistent methods used; and results from environmental monitoring and the associated dose calculations reported over the 27 years from 1957 through 1984 do not suggest a significant dose contribution from the buildup in the environment of radioactive materials associated with Hanford operations.

  6. A spatio-temporal mining approach towards summarizing and analyzing protein folding trajectories

    2007-04-01

    Full Text Available Abstract Understanding the protein folding mechanism remains a grand challenge in structural biology. In the past several years, computational theories in molecular dynamics have been employed to shed light on the folding process. Coupled with high computing power and large scale storage, researchers now can computationally simulate the protein folding process in atomistic details at femtosecond temporal resolution. Such simulation often produces a large number of folding trajectories, each consisting of a series of 3D conformations of the protein under study. As a result, effectively managing and analyzing such trajectories is becoming increasingly important. In this article, we present a spatio-temporal mining approach to analyze protein folding trajectories. It exploits the simplicity of contact maps, while also integrating 3D structural information in the analysis. It characterizes the dynamic folding process by first identifying spatio-temporal association patterns in contact maps, then studying how such patterns evolve along a folding trajectory. We demonstrate that such patterns can be leveraged to summarize folding trajectories, and to facilitate the detection and ordering of important folding events along a folding path. We also show that such patterns can be used to identify a consensus partial folding pathway across multiple folding trajectories. Furthermore, we argue that such patterns can capture both local and global structural topology in a 3D protein conformation, thereby facilitating effective structural comparison amongst conformations. We apply this approach to analyze the folding trajectories of two small synthetic proteins-BBA5 and GSGS (or Beta3S. We show that this approach is promising towards addressing the above issues, namely, folding trajectory summarization, folding events detection and ordering, and consensus partial folding pathway identification across trajectories.

    2012-03-01

    Full Text Available Abstract Background The availability of large-scale curated protein interaction datasets has given rise to the opportunity to investigate higher level organization and modularity within the protein interaction network (PPI using graph theoretic analysis. Despite the recent progress, systems level analysis of PPIS remains a daunting task as it is challenging to make sense out of the deluge of high-dimensional interaction data. Specifically, techniques that automatically abstract and summarize PPIS at multiple resolutions to provide high level views of its functional landscape are still lacking. We present a novel data-driven and generic algorithm called FUSE (Functional Summary Generator that generates functional maps of a PPI at different levels of organization, from broad process-process level interactions to in-depth complex-complex level interactions, through a pro t maximization approach that exploits Minimum Description Length (MDL principle to maximize information gain of the summary graph while satisfying the level of detail constraint. Results We evaluate the performance of FUSE on several real-world PPIS. We also compare FUSE to state-of-the-art graph clustering methods with GO term enrichment by constructing the biological process landscape of the PPIS. Using AD network as our case study, we further demonstrate the ability of FUSE to quickly summarize the network and identify many different processes and complexes that regulate it. Finally, we study the higher-order connectivity of the human PPI. Conclusion By simultaneously evaluating interaction and annotation data, FUSE abstracts higher-order interaction maps by reducing the details of the underlying PPI to form a functional summary graph of interconnected functional clusters. Our results demonstrate its effectiveness and superiority over state-of-the-art graph clustering methods with GO term enrichment.

    To iteratively design a prototype of a computerized clinical knowledge summarization (CKS) tool aimed at helping clinicians finding answers to their clinical questions; and to conduct a formative assessment of the usability, usefulness, efficiency, and impact of the CKS prototype on physicians' perceived decision quality compared with standard search of UpToDate and PubMed. Mixed-methods observations of the interactions of 10 physicians with the CKS prototype vs. standard search in an effort to solve clinical problems posed as case vignettes. The CKS tool automatically summarizes patient-specific and actionable clinical recommendations from PubMed (high quality randomized controlled trials and systematic reviews) and UpToDate. Two thirds of the study participants completed 15 out of 17 usability tasks. The median time to task completion was less than 10s for 12 of the 17 tasks. The difference in search time between the CKS and standard search was not significant (median=4.9 vs. 4.5m in). Physician's perceived decision quality was significantly higher with the CKS than with manual search (mean=16.6 vs. 14.4; p=0.036). The CKS prototype was well-accepted by physicians both in terms of usability and usefulness. Physicians perceived better decision quality with the CKS prototype compared to standard search of PubMed and UpToDate within a similar search time. Due to the formative nature of this study and a small sample size, conclusions regarding efficiency and efficacy are exploratory. Published by Elsevier Ireland Ltd.

    Meghdadi, Amir H; Irani, Pourang

    2013-12-01

    We propose a novel video visual analytics system for interactive exploration of surveillance video data. Our approach consists of providing analysts with various views of information related to moving objects in a video. To do this we first extract each object's movement path. We visualize each movement by (a) creating a single action shot image (a still image that coalesces multiple frames), (b) plotting its trajectory in a space-time cube and (c) displaying an overall timeline view of all the movements. The action shots provide a still view of the moving object while the path view presents movement properties such as speed and location. We also provide tools for spatial and temporal filtering based on regions of interest. This allows analysts to filter out large amounts of movement activities while the action shot representation summarizes the content of each movement. We incorporated this multi-part visual representation of moving objects in sViSIT, a tool to facilitate browsing through the video content by interactive querying and retrieval of data. Based on our interaction with security personnel who routinely interact with surveillance video data, we identified some of the most common tasks performed. This resulted in designing a user study to measure time-to-completion of the various tasks. These generally required searching for specific events of interest (targets) in videos. Fourteen different tasks were designed and a total of 120 min of surveillance video were recorded (indoor and outdoor locations recording movements of people and vehicles). The time-to-completion of these tasks were compared against a manual fast forward video browsing guided with movement detection. We demonstrate how our system can facilitate lengthy video exploration and significantly reduce browsing time to find events of interest. Reports from expert users identify positive aspects of our approach which we summarize in our recommendations for future video visual analytics systems.

  10. Assumption-versus data-based approaches to summarizing species' ranges.

    Peterson, A Townsend; Navarro-Sigüenza, Adolfo G; Gordillo, Alejandro

    2016-08-04

    For conservation decision making, species' geographic distributions are mapped using various approaches. Some such efforts have downscaled versions of coarse-resolution extent-of-occurrence maps to fine resolutions for conservation planning. We examined the quality of the extent-of-occurrence maps as range summaries and the utility of refining those maps into fine-resolution distributional hypotheses. Extent-of-occurrence maps tend to be overly simple, omit many known and well-documented populations, and likely frequently include many areas not holding populations. Refinement steps involve typological assumptions about habitat preferences and elevational ranges of species, which can introduce substantial error in estimates of species' true areas of distribution. However, no model-evaluation steps are taken to assess the predictive ability of these models, so model inaccuracies are not noticed. Whereas range summaries derived by these methods may be useful in coarse-grained, global-extent studies, their continued use in on-the-ground conservation applications at fine spatial resolutions is not advisable in light of reliance on assumptions, lack of real spatial resolution, and lack of testing. In contrast, data-driven techniques that integrate primary data on biodiversity occurrence with remotely sensed data that summarize environmental dimensions (i.e., ecological niche modeling or species distribution modeling) offer data-driven solutions based on a minimum of assumptions that can be evaluated and validated quantitatively to offer a well-founded, widely accepted method for summarizing species' distributional patterns for conservation applications. © 2016 Society for Conservation Biology.

How to have a healthy diet involves many aspects including politics, economy, and culture. China had books on diet quite long time ago. The early and middle period of Qing Dynasty reached the highest stage of development of China's ancient diet literature, which not only summarized the previous generations' diet literature, but also enriched their contents and had a positive effect on the development of modern diet literature. Diet monographs account for a crucial part among the numerous culinary literatures in Qing Dynasty, and they can best embody the achievements of this period. However, the study of diet monographs of the early and middle period of Qing Dynasty is relatively weak. Although there are papers researching on some of those monographs, overall analysis and discussion are insufficient. Therefore, it is very necessary to study the diet monographs of the early and middle period of Qing Dynasty from the point of historical literature view.

    Mantle cell lymphoma (MCL) is a rare subtype of non-Hodgkin lymphoma characterized by CD5 expression and a t(11;14) cytogenetic translocation that results in overexpression of the cyclin D1 gene. Currently, there is no standard of care for the treatment of MCL, and patient prognosis is poor. Traditional treatments for MCL rely on conventional chemotherapy agents, including cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). The addition of the immunotherapeutic agent rituximab to this regimen (CHOP-R) has helped to improve patient response to treatment. These treatments often provide good initial responses that are difficult to sustain. Therefore, a number of newer agents and combinations have been investigated to produce more durable benefit. Several of these advances were reported at the 51st American Society of Hematology (ASH) Annual Meeting and Exposition, held December 5-8, 2009 in New Orleans, Louisiana. In this clinical roundtable monograph, new strategies in the treatment of MCL are discussed. Some of the drug classes examined here are proteasome inhibitors, inhibitors of the protein mammalian target of rapamycin (mTOR), the unique alkylating agent bendamustine, and immunomodulatory agents.

    2014-01-01

    In this monograph, the authors discuss the current progress in the medical application of impedimetric biosensors, along with the key challenges in the field. First, a general overview of biosensor development, structure and function is presented, followed by a detailed discussion of impedimetric biosensors and the principles of electrochemical impedance spectroscopy. Next, the current state-of-the art in terms of the science and technology underpinning impedance-based biosensors is reviewed in detail. The layer-by-layer construction of impedimetric sensors is described, including the design of electrodes, their nano-modification, transducer surface functionalization and the attachment of different bioreceptors. The current challenges of translating lab-based biosensor platforms into commercially-available devices that function with real patient samples at the POC are presented; this includes a consideration of systems integration, microfluidics and biosensor regeneration. The final section of this monograph ...

    2016-07-01

    Full Text Available Subject of Research.The competitive advantage of a modern specialist is the widest possible coverage of informationsources useful from the point of view of obtaining and acquisition of relevant professionally significant information. Among these sources professional web forums occupy a significant place. The paperconsiders the problem of automaticforum text summarization, i.e. identification ofthose fragments that contain professionally relevant information. Method.The research is based on statistical analysis of texts of forums by means of machine learning. Six web forums were selected for research considering aspects of technologies of various subject domains as their subject-matter. The marking of forums was carried out by an expert way. Using various methods of machine learning the models were designed reflecting functional communication between the estimated characteristics of PSI extraction quality and signs of posts. The cumulative NDCG metrics and its dispersion were used for an assessment of quality of models.Main Results. We have shown that an important role in an assessment of PSI extraction efficiency is played by requestcontext. The contexts of requestshave been selected,characteristic of PSI extraction, reflecting various interpretations of information needs of users, designated by terms relevance and informational content. The scales for their estimates have been designed corresponding to worldwide approaches. We have experimentally confirmed that results of the summarization of forums carried out by experts manually significantly depend on requestcontext. We have shown that in the general assessment of PSI extraction efficiency relevance is rather well described by a linear combination of features, and the informational content assessment already requires their nonlinear combination. At the same time at a relevance assessment the leading role is played by the features connected with keywords, and at an informational content

    The aim of this study was to characterize the role of the USA in the global exchange of wildlife and describe high volume trade with an eye toward prioritizing health risk assessment questions for further analysis. Here we summarize nearly 14 years (2000-2013) of the most comprehensive data available (USFWS LEMIS system), involving 11 billion individual specimens and an additional 977 million kilograms of wildlife. The majority of shipments contained mammals (27%), while the majority of specimens imported were shells (57%) and tropical fish (25%). Most imports were facilitated by the aquatic and pet industry, resulting in one-third of all shipments containing live animals. The importer reported origin of wildlife was 77.7% wild-caught and 17.7% captive-reared. Indonesia was the leading exporter of legal shipments, while Mexico was the leading source reported for illegal shipments. At the specimen level, China was the leading exporter of legal and illegal wildlife imports. The number of annual declared shipments doubled during the period examined, illustrating continually increasing demand, which reinforces the need to scale up capacity for border inspections, risk management protocols and disease surveillance. Most regulatory oversight of wildlife trade is aimed at conservation, rather than prevention of disease introduction.

  19. LexRank: Graph-based Lexical Centrality as Salience in Text Summarization

    CERN Document Server

    Erkan, G; 10.1613/jair.1523

    2011-01-01

    We introduce a stochastic graph-based method for computing relative importance of textual units for Natural Language Processing. We test the technique on the problem of Text Summarization (TS). Extractive TS relies on the concept of sentence salience to identify the most important sentences in a document or set of documents. Salience is typically defined in terms of the presence of particular important words or in terms of similarity to a centroid pseudo-sentence. We consider a new approach, LexRank, for computing sentence importance based on the concept of eigenvector centrality in a graph representation of sentences. In this model, a connectivity matrix based on intra-sentence cosine similarity is used as the adjacency matrix of the graph representation of sentences. Our system, based on LexRank ranked in first place in more than one task in the recent DUC 2004 evaluation. In this paper we present a detailed analysis of our approach and apply it to a larger data set including data from earlier DUC evaluatio...

    2017-03-01

    A video is understood by users in terms of entities present in it. Entity Discovery is the task of building appearance model for each entity (e.g., a person), and finding all its occurrences in the video. We represent a video as a sequence of tracklets, each spanning 10-20 frames, and associated with one entity. We pose Entity Discovery as tracklet clustering, and approach it by leveraging Temporal Coherence (TC): the property that temporally neighboring tracklets are likely to be associated with the same entity. Our major contributions are the first Bayesian nonparametric models for TC at tracklet-level. We extend Chinese Restaurant Process (CRP) to TC-CRP, and further to Temporally Coherent Chinese Restaurant Franchise (TC-CRF) to jointly model entities and temporal segments using mixture components and sparse distributions. For discovering persons in TV serial videos without meta-data like scripts, these methods show considerable improvement over state-of-the-art approaches to tracklet clustering in terms of clustering accuracy, cluster purity and entity coverage. The proposed methods can perform online tracklet clustering on streaming videos unlike existing approaches, and can automatically reject false tracklets. Finally we discuss entity-driven video summarization- where temporal segments of the video are selected based on the discovered entities, to create a semantically meaningful summary.

  1. Summarizing and visualizing structural changes during the evolution of biomedical ontologies using a Diff Abstraction Network.

    Biomedical ontologies are a critical component in biomedical research and practice. As an ontology evolves, its structure and content change in response to additions, deletions and updates. When editing a biomedical ontology, small local updates may affect large portions of the ontology, leading to unintended and potentially erroneous changes. Such unwanted side effects often go unnoticed since biomedical ontologies are large and complex knowledge structures. Abstraction networks, which provide compact summaries of an ontology's content and structure, have been used to uncover structural irregularities, inconsistencies and errors in ontologies. In this paper, we introduce Diff Abstraction Networks ("Diff AbNs"), compact networks that summarize and visualize global structural changes due to ontology editing operations that result in a new ontology release. A Diff AbN can be used to support curators in identifying unintended and unwanted ontology changes. The derivation of two Diff AbNs, the Diff Area Taxonomy and the Diff Partial-area Taxonomy, is explained and Diff Partial-area Taxonomies are derived and analyzed for the Ontology of Clinical Research, Sleep Domain Ontology, and eagle-i Research Resource Ontology. Diff Taxonomy usage for identifying unintended erroneous consequences of quality assurance and ontology merging are demonstrated. Copyright © 2015 Elsevier Inc. All rights reserved.

  2. ARABIC TEXT SUMMARIZATION BASED ON LATENT SEMANTIC ANALYSIS TO ENHANCE ARABIC DOCUMENTS CLUSTERING

    2013-01-01

    Full Text Available Arabic Documents Clustering is an important task for obtaining good results with the traditional Information Retrieval (IR systems especially with the rapid growth of the number of online documents present in Arabic language. Documents clustering aim to automatically group similar documents in one cluster using different similarity/distance measures. This task is often affected by the documents length, useful information on the documents is often accompanied by a large amount of noise, and therefore it is necessary to eliminate this noise while keeping useful information to boost the performance of Documents clustering. In this paper, we propose to evaluate the impact of text summarization using the Latent Semantic Analysis Model on Arabic Documents Clustering in order to solve problems cited above, using five similarity/distance measures: Euclidean Distance, Cosine Similarity, Jaccard Coefficient, Pearson Correlation Coefficient and Averaged Kullback-Leibler Divergence, for two times: without and with stemming. Our experimental results indicate that our proposed approach effectively solves the problems of noisy information and documents length, and thus significantly improve the clustering performance.

    Full Text Available Veterinary care plays an influential role in sea turtle rehabilitation, especially in endangered species. Physiological characteristics, hematological and plasma biochemistry profiles, are useful references for clinical management in animals, especially when animals are during the convalescence period. In this study, these factors associated with sea turtle surviving were analyzed. The blood samples were collected when sea turtles remained alive, and then animals were followed up for surviving status. The results indicated that significantly negative correlation was found between buoyancy disorders (BD and sea turtle surviving (p < 0.05. Furthermore, non-surviving sea turtles had significantly higher levels of aspartate aminotranspherase (AST, creatinine kinase (CK, creatinine and uric acid (UA than surviving sea turtles (all p < 0.05. After further analysis by multiple logistic regression model, only factors of BD, creatinine and UA were included in the equation for calculating summarized health index (SHI for each individual. Through evaluation by receiver operating characteristic (ROC curve, the result indicated that the area under curve was 0.920 ± 0.037, and a cut-off SHI value of 2.5244 showed 80.0% sensitivity and 86.7% specificity in predicting survival. Therefore, the developed SHI could be a useful index to evaluate health status of sea turtles and to improve veterinary care at rehabilitation facilities.

    Literature and experimental data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate release (IR) solid oral dosage forms containing piroxicam in the free acid form are reviewed. Piroxicam solubility and permeability, its therapeutic use and therapeutic index, pharmacokinetic properties, data related to the possibility of excipient interactions and reported BE/bioavailability (BA), and corresponding dissolution data are taken into consideration. The available data suggest that according to the current biopharmaceutics classification system (BCS) and all current guidances, piroxicam would be assigned to BCS Class II. The extent of piroxicam absorption seems not to depend on manufacturing conditions or excipients, so the risk of bioinequivalence in terms of area under the curve (AUC) is very low, but the rate of absorption (i.e., BE in terms of Cmax ) can be affected by the formulation. Current in vitro dissolution methods may not always reflect differences in terms of Cmax for BCS Class II weak acids; however, minor differences in absorption rate of piroxicam would not subject the patient to unacceptable risks: as piroxicam products may be taken before or after meals, the rate of absorption cannot be considered crucial to drug action. Therefore, a biowaiver for IR piroxicam solid oral dosage form is considered feasible, provided that (a) the test product contains only excipients, which are also present in IR solid oral drug products containing piroxicam, which have been approved in ICH or associated countries, for instance, those presented in Table 3 of this paper; (b) both the test and comparator drug products dissolve 85% in 30 min or less at pH 1.2, 4.5, and 6.8; and (c) the test product and comparator show dissolution profile similarity in pH 1.2, 4.5, and 6.8. When not all of these conditions can be fulfilled, BE of the products should be established in vivo.

    Mackay and Burnet's Autoimmune diseases, published in 1962, marked the beginning of autoimmunity as a clinical science and led to the future acceptance of the existence of autoimmunity. While there is still controversy regarding the mechanisms of autoimmunity, the authors' insightful hypothesis based on clonal selection theory and the emergence of "forbidden clones", due to somatic mutations, is still current, with recent evidence giving further credence to this hypothesis. We salute Mackay and Burnet on the 50th anniversary of this seminal publication. It is particularly pleasing that it has an iconic Australian origin.

    How to quickly and effectively exchange video information with the user is a major task for video searching engine's user interface. In this paper, we proposed to use Moving Edge Overlaid Frame (MEOF) image to summarize both the local object motion and global camera motion information of the video clip into a single image. MEOF will supplement the motion information that is generally dropped by the key frame representation, and it will enable faster perception for the user than viewing the actual video. The key technology of our MEOF generating algorithm involves the global motion estimation (GME). In order to extract the precise global motion model from general video, our GME module takes two stages, the match based initial GME and the gradient based GME refinement. The GME module also maintains a sprite image that will be aligned with the new input frame in the background after the global motion compensation transform. The difference between the aligned sprite and the new frame will be used to extract the masks that will help to pick out the moving objects' edges. The sprite is updated with each input frame and the moving edges are extracted at a constant interval. After all the frames are processed, the extracted moving edges are overlaid to the sprite according to there global motion displacement with the sprite and the temporal distance with the last frame, thus create our MEOF image. Experiments show that the MEOF representation of the video clip helps the user acquire the motion knowledge much faster and also be compact enough to serve the needs of online applications.

    2016-04-01

    Starting in 2017, all state and federal health insurance exchanges will present quality data on health plans in addition to cost information. We analyzed variations in the current design of information on state exchanges to identify presentation approaches that encourage consumers to take quality as well as cost into account when selecting a health plan. Using an online sample of 1,025 adults, we randomly assigned participants to view the same comparative information on health plans, displayed in different ways. We found that consumers were much more likely to select a high-value plan when cost information was summarized instead of detailed, when quality stars were displayed adjacent to cost information, when consumers understood that quality stars signified the quality of medical care, and when high-value plans were highlighted with a check mark or blue ribbon. These approaches, which were equally effective for participants with higher and lower numeracy, can inform the development of future displays of plan information in the exchanges.

    Literature data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate release (IR) solid oral dosage forms containing prednisone are reviewed. Due to insufficient data prednisone cannot be definitively classified according to the current Biopharmaceutics Classification System (BCS) criteria as both the solubility and the permeability of prednisone are on the borderline of the present criteria of BCS Class I. Prednisone's therapeutic indications and therapeutic index, pharmacokinetics and the possibility of excipient interactions were also taken into consideration. Available evidence indicates that a biowaiver for IR solid oral dosage forms formulated with the excipients tabulated in this article would be unlikely to expose patients to undue risks.

Cimetidine's therapeutic use and therapeutic index, its pharmacokinetic properties, data related to the possibility of excipient interactions, and reported BE/bioavailability (BA) problems were also taken into consideration. On the basis of the overall evidence, a biowaiver can be recommended for cimetidine IR products, provided that the test product contains only those excipients reported in this paper in their usual amounts, and that the test and the comparator drug products both are "rapidly dissolving" as per BCS.

    2012-01-01

    The technology of automatic document summarization is maturing and may provide a solution to the information overload problem. Nowadays, document summarization plays an important role in information retrieval. With a large volume of documents, presenting the user with a summary of each document greatly facilitates the task of finding the desired documents. Document summarization is a process of automatically creating a compressed version of a given document that provides useful information to users, and multi-document summarization is to produce a summary delivering the majority of information content from a set of documents about an explicit or implicit main topic. The lexical cohesion structure of the text can be exploited to determine the importance of a sentence/phrase. Lexical chains are useful tools to analyze the lexical cohesion structure in a text .In this paper we consider the effect of the use of lexical cohesion features in Summarization, And presenting a algorithm base on the knowledge base.

    Identifying cancer hazards is the first step towards cancer prevention. The International Agency for Research on Cancer (IARC) Monographs Programme, which has evaluated nearly 1,000 agents for their carcinogenic potential since 1971, typically selects agents for hazard identification on the basis of public nominations, expert advice, published data on carcinogenicity, and public health importance. Here, we present a novel and complementary strategy for identifying agents for hazard evaluation using chemoinformatics, database integration, and automated text mining. To inform selection among a broad range of pesticides nominated for evaluation, we identified and screened nearly 6,000 relevant chemical structures, after which we systematically compiled information on 980 pesticides, creating network maps that allowed cluster visualization by chemical similarity, pesticide class, and publicly available information concerning cancer epidemiology, cancer bioassays, and carcinogenic mechanisms. For the IARC Monograph meetings that took place in March and June 2015, this approach supported high-priority evaluation of glyphosate, malathion, parathion, tetrachlorvinphos, diazinon, p,p'-dichlorodiphenyltrichloroethane (DDT), lindane, and 2,4-dichlorophenoxyacetic acid (2,4-D). This systematic approach, accounting for chemical similarity and overlaying multiple data sources, can be used by risk assessors as well as by researchers to systematize, inform, and increase efficiency in selecting and prioritizing agents for hazard identification, risk assessment, regulation, or further investigation. This approach could be extended to an array of outcomes and agents, including occupational carcinogens, drugs, and foods. Citation: Guha N, Guyton KZ, Loomis D, Barupal DK. 2016.

    2015-09-01

    Literature and experimental data relevant for the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate release (IR) solid oral dosage forms containing levetiracetam are reviewed. Data on solubility and permeability suggest that levetiracetam belongs to class I of the biopharmaceutical classification system (BCS). Levetiracetam's therapeutic use, its wide therapeutic index, and its favorable pharmacokinetic properties make levetiracetam a valid candidate for the BCS-based biowaiver approach. Further, no BE studies with levetiracetam IR formulations in which the test formulation failed to show BE with the comparator have been reported in the open literature. On the basis of the overall evidence, it appears unlikely that a BCS-based biowaiver approach for levetiracetam IR solid oral dosage forms formulated with established excipients would expose patients to undue risks. Thus, the BCS-based biowaiver approach procedure is recommended for IR solid oral dosage form containing levetiracetam, provided the excipients in the formulation are also present in products that have been approved in countries belonging to or associated with the International Committee on Harmonization and are used in their usual quantities, and provided the dissolution profiles of the test and reference product comply with the current requirements for BCS-based biowaivers.

    Literature data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate release (IR) solid oral dosage forms containing levofloxacin as the only active pharmaceutical ingredient (API) are reviewed. According to the current Biopharmaceutics Classification System, levofloxacin can be assigned to Class I. No problems with BE of IR levofloxacin formulations containing different excipients and produced by different manufacturing methods have been reported and hence the risk of bioinequivalence caused by these factors appears to be low. In addition, levofloxacin has a wide therapeutic index. On the basis of this evidence, a biowaiver is recommended for IR solid oral dosage forms containing levofloxacin as the single API provided that (a) the test product contains only excipients present in IR levofloxacin drug products that have been approved in International Conference on Harmonization (ICH) or associated countries and which have the same dosage form; (b) both the test and comparator dosage form are "very rapidly dissolving" or "rapidly dissolving" with similarity of the dissolution profiles demonstrated at pH 1.2, 4.5, and 6.8; and (c) if the test product contains polysorbates, it should be both qualitatively and quantitatively identical to its comparator in terms of polysorbate content.

    The National Library of Medicine's (NLM) monographic resources in the medical behavioral sciences (MBS) were examined to assess NLM's ability to support the needs of researchers writing in this area. A sample of 239 representative monographs derived from citations in MBS-related articles published in 61 journals in 1981 were evaluated. These monographs were limited to works published between 1978 and 1981, inclusive. The subject distribution of the sample included fourteen of the twenty-one main classes in the LC classification, although BF (psychology), H (social sciences), and R (medicine) constituted 80.3% of the sample. The study revealed that NLM held 48.5% of the sample. The holdings of ten research medical libraries, including six of the seven regional medical libraries, were also evaluated in order to gauge NLM's ability to support that element of the medical library network. The holding rates of these libraries ranged widely (9.6% to 36%), although NLM was found to have far more extensive holdings overall, and when assessed against classes BF, H, and R. Overall, NLM could have supplied from 28.8% to 44.5% of the monographs not held by the medical libraries. In only a few cases were the ten medical libraries able to provide access to monographs not held by NLM. The findings of the study indicate that, regardless of NLM's indication of support to the MBS area, the holdings of more general research and academic libraries are essential to support the monograph needs of MBS researchers.

    Full Text Available This paper examines the martial arts monographs published in Spain between 1906 and 2006 from a bibliometric point of view. Starting from Pérez and Gutiérrez’s previous bibliography (2008, the total number of published monographs following the criteria of subject, decade and the combination of both was analyzed. The results showed a total of 2.036 books (1.285 original editions with a prevalence of Japanese and Chinese martial arts. A group of eight subjects exceeded a hundred volumes (karate, judo/jujutsu, taijiquan, wu-shu/kung fu, classics, qigong, philosophy, history and education, and aikido, with two patterns of bibliographic evolution appearing. The first, represented by Japanese martial arts considered as a group and martial arts focused on the utilitarian and/or sporting performance aspects (judo/jujutsu, karate and wu-shu/kung fu, developed increasingly until the 80’s when it followed a steady-state and/or drop. The second model, which characterises the Chinese martial arts group and martial arts mainly focused on healthy and/or spiritual aspects of training (taijiquan, qigong, aikido, has increased significantly from the 90’s until the present moment. The interpretation of these patterns and the evolution of the martial arts bibliographic production in Spain highlights some aspects such as the development of the Spanish society and sports practice, bibliographic production, reading habits, or the cultural influences of eastern countries on Spain.

    Howe, Nina

    2017-09-01

    Volling et al.'s monograph provides a rich, thoughtful, and rigorous account of how the transition to siblinghood is experienced by the first-born child and the family. In their comprehensive longitudinal study, they followed 241 families from the prenatal period before the second-born's birth until this child was 12-months old. Siblings are a critical, but understudied, relationship in children's development; the challenges posed in researching sibling dynamics in the context of the family are discussed. Prior psychodynamic and developmental research literature is critiqued, which places the current study into perspective and indicates the important theoretical frameworks (i.e., developmental psychopathology and developmental ecological systems) employed by Volling et al. to advance our understanding of this critical transition in the life of the family. The longitudinal study design, sample characteristics, identification of possible trajectories of adjustment (or not) to the birth of the sibling, and selection of family and child variables are addressed. The sophisticated statistical methods (Growth Mixture Modeling and data mining procedures) employed to predict child adjustment in association with parenting variables over time and sibling relationship quality at 12 months identified low- and high-risk trajectories on the seven subscales of the Child Behavior Check List (CBCL). This afforded a nuanced investigation of a variety of potentially problematic child behaviors (e.g., aggression, withdrawal, negative emotionality, somatic problems) in association with parenting behaviors. A final discussion included study limitations, significant strengths, and implications for clinicians and other professionals. The study's conclusion is that most children and families are resilient, take the birth of a sibling in their stride, and do not exhibit empirical evidence of a developmental crisis, as argued by earlier psychodynamic authors. © 2017 The Society for Research

  7. Video summarization using descriptors of motion activity: a motion activity based approach to key-frame extraction from video shots

    Divakaran, Ajay; Radhakrishnan, Regunathan; Peker, Kadir A.

    2001-10-01

    We describe a video summarization technique that uses motion descriptors computed in the compressed domain. It can either speed up conventional color-based video summarization techniques, or rapidly generate a key-frame based summary by itself. The basic hypothesis of the work is that the intensity of motion activity of a video segment is a direct indication of its `summarizability,' which we experimentally verify using the MPEG-7 motion activity descriptor and the fidelity measure proposed in H. S. Chang, S. Sull, and S. U. Lee, `Efficient video indexing scheme for content-based retrieval,' IEEE Trans. Circuits Syst. Video Technol. 9(8), (1999). Note that the compressed domain extraction of motion activity intensity is much simpler than the color-based calculations. We are thus able to quickly identify easy to summarize segments of a video sequence since they have a low intensity of motion activity. We are able to easily summarize these segments by simply choosing their first frames. We can then apply conventional color-based summarization techniques to the remaining segments. We thus speed up color-based summarization by reducing the number of segments processed. Our results also motivate a simple and novel key-frame extraction technique that relies on a motion activity based nonuniform sampling of the frames. Our results indicate that it can either be used by itself or to speed up color-based techniques as explained earlier.

    To identify the current challenges and opportunities in compensation and recognition for pharmacist-provided immunizations across the lifespan and to establish guiding principles for pharmacist-provided immunization compensation and recognition. 22 stakeholders gathered on June 29, 2011, at the American Pharmacists Association (APhA) headquarters in Washington, DC, for a meeting on immunization compensation that was convened by APhA and the Academy of Managed Care Pharmacy. Participants included representatives from community pharmacy practices (chain, grocery, and independent), employers, national consumer health and advocacy organizations, national pharmacy and public health organizations, health plan representatives, pharmacy benefit managers, and health information technology, standards, and safety organizations. Key immunization leaders from TRICARE Management Activity, the Centers for Medicare & Medicaid Services, the National Vaccine Program Office of the Department of Health & Human Services, and the Centers for Disease Control and Prevention (CDC) also participated in the meeting. The increased numbers of pharmacists providing vaccination services and the availability of pharmacist-provided immunizations to populations in need of vaccines has continued to increase. This has resulted in a rise in the percentage of patients who receive vaccines at pharmacies. Pharmacists are now working to lever-age their ability to identify people with key risk factors (e.g., diabetes, heart disease or previous myocardial infarction), encourage them to receive their CDC-recommended vaccinations, and administer the required vaccine. Challenges and opportunities in compensation and recognition for pharmacist-provided immunizations across the adult lifespan persist. Variability in state practice acts, reimbursement and compensation processes and systems, and mechanisms for documentation of vaccine services create substantial differences in how pharmacist-provided immunizations

    Full Text Available This study aimed at comparing the effects of 'question-answer relationship strategy', 'summarizing', and 'syntactic structure identification training'on the reading comprehension of Iranian EFL learners. The participants were sixty (34 women and 26 men intermediate students who answered an English reading comprehension test consisting of three reading passages as the pretest. During the treatment, the students in the first group were supposed to summarize the passages. The subjects in the second group familiarized with the syntactic structure identification strategy and the ones in the third group were taught the question-answer relationship strategy. At the end of the treatment, an English reading comprehension test similar to the pretest was administered to the groups as a posttest. The results suggested that there is statistically significant difference between the reading comprehension abilities of the three classes. Furthermore the use of QAR strategy led to better comprehension of reading texts with syntactic structure training and summarizing between which there was no significant difference. Keywords: Reading comprehension, summarization, question-answer relationship, syntactic structure

    Full Text Available Globalization of traditional Chinese medicines started around 1996, which was initiated by the Chinese government. However, substantial progress was only achieved in recent years including the adoption of TCM quality monographs in the western pharmacopoeias (United States Pharmacopoeia and European Pharmacopoeia and registration in main stream drug regulatory agencies such as US Food and Drug Administration (FDA and European Medicines Agency (EMA. So far, several TCM herbal quality monographs were adopted by the United States Pharmacopoeia including Chinese Salvia, Ganoderma lucidum and Panax notoginseng, etc. Over 45 TCM quality monographs were recorded in the European Pharmacopoeia with 20 more in progress. After the successful registration of the first TCM product named Diao Xin Xue Kang as traditional medicine via the Medicines Evaluation Board of the Netherlands, several other TCM herbal products are in the registration process in several European member states. So far, there has been still not any TCM product authorized as a drug by the FDA regardless of a few TCM products in phase III or phase II clinical trials. This review summarizes the progress made in the globalization of traditional Chinese medicines in recent years and future issues in this regard.

  6. Some Reflections on the Task of Content Determination in the Context of Multi-Document Summarization of Evolving Events

    Afantenos, Stergos D

    2007-01-01

    Despite its importance, the task of summarizing evolving events has received small attention by researchers in the field of multi-document summariztion. In a previous paper (Afantenos et al. 2007) we have presented a methodology for the automatic summarization of documents, emitted by multiple sources, which describe the evolution of an event. At the heart of this methodology lies the identification of similarities and differences between the various documents, in two axes: the synchronic and the diachronic. This is achieved by the introduction of the notion of Synchronic and Diachronic Relations. Those relations connect the messages that are found in the documents, resulting thus in a graph which we call grid. Although the creation of the grid completes the Document Planning phase of a typical NLG architecture, it can be the case that the number of messages contained in a grid is very large, exceeding thus the required compression rate. In this paper we provide some initial thoughts on a probabilistic model ...

    This paper describes the comparative evaluation of an experimental automated text summarization system, Centrifuser and three conventional search engines - Google, Yahoo and About.com. Centrifuser provides information to patients and families relevant to their questions about specific health conditions. It then produces a multidocument summary of articles retrieved by a standard search engine, tailored to the user's question. Subjects, consisting of friends or family of hospitalized patients, were asked to "think aloud" as they interacted with the four systems. The evaluation involved audio- and video recording of subject interactions with the interfaces in situ at a hospital. Results of the evaluation show that subjects found Centrifuser's summarization capability useful and easy to understand. In comparing Centrifuser to the three search engines, subjects' ratings varied; however, specific interface features were deemed useful across interfaces. We conclude with a discussion of the implications for engineering Web-based retrieval systems.

  8. Mobile-Cloud Assisted Video Summarization Framework for Efficient Management of Remote Sensing Data Generated by Wireless Capsule Sensors

    Directory of Open Access Journals (Sweden)

    Irfan Mehmood

    2014-09-01

    Full Text Available Wireless capsule endoscopy (WCE has great advantages over traditional endoscopy because it is portable and easy to use, especially in remote monitoring health-services. However, during the WCE process, the large amount of captured video data demands a significant deal of computation to analyze and retrieve informative video frames. In order to facilitate efficient WCE data collection and browsing task, we present a resource- and bandwidth-aware WCE video summarization framework that extracts the representative keyframes of the WCE video contents by removing redundant and non-informative frames. For redundancy elimination, we use Jeffrey-divergence between color histograms and inter-frame Boolean series-based correlation of color channels. To remove non-informative frames, multi-fractal texture features are extracted to assist the classification using an ensemble-based classifier. Owing to the limited WCE resources, it is impossible for the WCE system to perform computationally intensive video summarization tasks. To resolve computational challenges, mobile-cloud architecture is incorporated, which provides resizable computing capacities by adaptively offloading video summarization tasks between the client and the cloud server. The qualitative and quantitative results are encouraging and show that the proposed framework saves information transmission cost and bandwidth, as well as the valuable time of data analysts in browsing remote sensing data.

  9. An Automatic Multidocument Text Summarization Approach Based on Naïve Bayesian Classifier Using Timestamp Strategy

    Directory of Open Access Journals (Sweden)

    Nedunchelian Ramanujam

    2016-01-01

    Full Text Available Nowadays, automatic multidocument text summarization systems can successfully retrieve the summary sentences from the input documents. But, it has many limitations such as inaccurate extraction to essential sentences, low coverage, poor coherence among the sentences, and redundancy. This paper introduces a new concept of timestamp approach with Naïve Bayesian Classification approach for multidocument text summarization. The timestamp provides the summary an ordered look, which achieves the coherent looking summary. It extracts the more relevant information from the multiple documents. Here, scoring strategy is also used to calculate the score for the words to obtain the word frequency. The higher linguistic quality is estimated in terms of readability and comprehensibility. In order to show the efficiency of the proposed method, this paper presents the comparison between the proposed methods with the existing MEAD algorithm. The timestamp procedure is also applied on the MEAD algorithm and the results are examined with the proposed method. The results show that the proposed method results in lesser time than the existing MEAD algorithm to execute the summarization process. Moreover, the proposed method results in better precision, recall, and F-score than the existing clustering with lexical chaining approach.

  10. The impact of the EMA change in definition of "dose" on the BCS dose-solubility ratio: a review of the biowaiver monographs.

    Science.gov (United States)

    Sediq, Ahmad; Kubbinga, Marlies; Langguth, Peter; Dressman, Jennifer

    2014-01-01

    The Biopharmaceutics Classification System (BCS) defines the solubility characteristics of an active pharmaceutical substance based on its dose-solubility ratio: for highly soluble drugs this ratio is less than 250 mL over a defined pH range. Prior to the revision of the European Medicines Agency (EMA, formerly EMEA) guideline in 2010, the "dose" in this ratio was consistently defined by the US FDA, the EMA, and the WHO biowaiver guidelines as the highest dosage strength. However, in the revised EMA guideline, the dose is defined as the highest single dose administered according to the Summary of Product Characteristics. The new EMA criterion for highly soluble may be closer to the actual conditions of use, but it is not in line with the dose that would be used in the in vivo bioequivalence study. This paper evaluates the impact on the BCS classification of the active pharmaceutical ingredients of the published biowaiver monographs and discusses the consequences of the possible change in classification on biowaiver recommendations. Using the current definition of dose by the EMA, the biowaiver recommendations for metoclopramide hydrochloride and verapamil hydrochloride are no longer valid according to EMA criteria. For prednisolone and prednisone, a reevaluation of the biowaiver recommendation, taking into account the usual dosing levels, seems appropriate.

    2013-08-01

    Literature data on the properties of zidovudine relevant to waiver of in vivo bioequivalence (BE) testing requirements for the approval of immediate-release (IR) solid oral dosage forms containing zidovudine alone or in combination with other active pharmaceutical ingredients (APIs) are reviewed. Solubility, dissolution, and permeability data for zidovudine, along with its dosing schedule, therapeutic index and pharmacokinetic properties, and reports related to BE/bioavailability were all taken into consideration. Data for solubility and permeability suggest that zidovudine belongs to Class I according to the Biopharmaceutics Classification System. Also, zidovudine is not a narrow therapeutic index drug. Although five out of 13 formulations tested in vivo (mostly of unreported composition) failed to show BE, it appears that in vitro studies performed according to biowaiver methods could predict in vivo behavior. Nevertheless, it is highly recommended that if a biowaiver is to be applied, excipient choices be limited to those found in IR drug products approved in International Conference on Harmonisation (ICH) or associated countries in the same dosage form (Table 2 of this monograph), in their usual amounts. These conclusions apply to products containing zidovudine as the only API and also to fixed combination products containing zidovudine with respect to the zidovudine component of the formulation.

  12. Biowaiver monographs for immediate-release solid oral dosage forms: quinine sulfate.

    2012-02-01

    The biowaiver approach permits evaluation of bioequivalence (BE) using a set of laboratory tests, obviating the need for expensive and time-consuming pharmacokinetic BE studies provided that both the active pharmaceutical ingredient and the formulations can meet the specified criteria. In the present monograph, the biowaiver-relevant data including solubility and permeability data, therapeutic use and therapeutic index, pharmacokinetic properties, reported excipient interactions, and BE/bioavailability studies of quinine sulfate are itemized and discussed. Quinine sulfate has borderline solubility characteristics and, on the whole, is highly permeable. Thus, depending on the jurisdiction, it is assigned to Biopharmaceutics Classification System class I or II. Although these characteristics would suggest a low risk of bioinequivalence among oral quinine products, a recent pharmacokinetic study showed bioinequivalence of two products. Even though quinine does not, strictly speaking, fit the definition of a narrow therapeutic index drug, it shows dose-related and, in some cases, irreversible side effects and toxicities at concentrations not far above the therapeutic concentration range. Taking all relevant aspects into consideration, a biowaiver cannot be recommended for new quinine immediate-release multisource products or major post-approval changes of already marketed quinine products, and in such cases, BE should be evaluated using an in vivo BE study.

    The present monograph reviews data relevant to applying the biowaiver procedure for the approval of immediate-release multisource solid dosage forms containing codeine phosphate. Both biopharmaceutical and clinical data of codeine were assessed. Solubility studies revealed that codeine meets the "highly soluble" criteria according to World Health Organization (WHO), the European Medicines Agency (EMA), and the United States Food and Drug Administration (US FDA). Codeine's fraction of dose absorbed in humans was reported to be high (>90%) based on cumulative urinary excretion of drug and drug-related material following oral administration. The permeability of codeine was also assessed to be high in both Caco-2 monolayers and rat intestinal perfusion studies. The main risks associated with codeine, that is, toxicity (attributed to CYP2D6 polymorphism) and its abuse potential, are present irrespective of the dosage form, and do not need to be taken into account for bioequivalence (BE) considerations. Taken together, codeine is a class 1 drug with manageable risk and is a good candidate for waiver of in vivo BE studies.

The USP-NF revisions arose from the Food and DrugAdministration’s (FDA’s requests to include, as part of each monograph’s Identification test, a limit test to detect the presence of Diethylene Glycol (DEG, a toxic adulterant. These revisions alignwith the 2007 FDA Guidance for Industry: Testing of Glycerin for Diethylene Glycol (1, that drug product manufacturers perform a specific identity test for DEG on all containers of all lots ofglycerin before glycerin is used in the manufacture and preparation of drug products. This paper describes several risk factors due to a complex global excipient supply chain, nonspecific specifications, inadequate supply chain qualification, and poor understanding of regulations. Strengthening and conformance to compendial specifications is one of the tools necessary to mitigate risk and help prevent the next DEG adulteration that is part of USP’s efforts to ensure safe medicines.

  15. Clinical roundtable monograph. New alternatives in CLL therapy: managing adverse events.

    Chronic lymphocytic leukemia (CLL) is a B-cell leukemia mainly affecting older adults. Historically, CLL has been regarded as an incurable disease, and treatment has been confined to cytotoxic chemotherapy regimens. However, prognosis for patients treated with these agents remained poor, prompting the development of new, targeted agents. The introduction of rituximab, a CD20-targeted monoclonal antibody, revolutionized the treatment for this disease. Rituximab in combination with fludarabine improved response rates and length of progression-free survival. The success of rituximab in this setting has prompted the development of many more investigational agents for CLL, including other antibody agents. However, as with any medication, the potential benefit achieved with CLL therapies is mitigated by the safety risk for the patient. These agents have been associated with adverse events such as immunosuppression, reactivation of cytomegalovirus, and infusion-related reactions that can occur with antibody administration. Adverse events can greatly affect the patient’s quality of life and ability to tolerate therapy. Management of adverse events is a critical component of the overall treatment strategy for CLL, particularly in elderly patients. In this clinical roundtable monograph, 3 expert physicians discuss the latest clinical studies evaluating the treatment of CLL, focusing on the adverse events associated with each agent and the potential interventions that can be used to manage their occurrence.

    A biowaiver monograph for acetylsalicylic acid (ASA) is presented. Literature and experimental data indicate that ASA is a highly soluble and highly permeable drug, leading to assignment of this active pharmaceutical ingredient (API) to Class I of the Biopharmaceutics Classification System (BCS). Limited bioequivalence (BE) studies reported in the literature indicate that products that have been tested are bioequivalent. Most of the excipients used in products with a marketing authorization in Europe are not considered to have an impact on gastrointestinal motility or permeability. Furthermore, ASA has a wide therapeutic index. Thus, the risks to the patient that might occur if a nonbioequivalent product were to be incorrectly deemed bioequivalent according to the biowaiver procedure appear to be minimal. As a result, the BCS-based biowaiver procedure can be recommended for approval of new formulations of solid oral dosage forms containing ASA as the only API, including both multisource and reformulated products, under the following conditions: (1) excipients are chosen from those used in ASA products already registered in International Conference on Harmonization and associated countries and (2) the dissolution profiles of the test and the comparator products comply with the BE guidance.

    Literature and experimental data relevant to waiver of in vivo bioequivalence (BE) testing for the approval of immediate-release solid oral dosage forms containing amoxicillin trihydrate are reviewed. Solubility and permeability characteristics according to the Biopharmaceutics Classification System (BCS), therapeutic uses, therapeutic index, excipient interactions, as well as dissolution and BE and bioavailability studies were taken into consideration. Solubility and permeability studies indicate that amoxicillin doses up to 875 mg belong to BCS class I, whereas 1000 mg belongs to BCS class II and doses of more than 1000 mg belong to BCS class IV. Considering all aspects, the biowaiver procedure can be recommended for solid oral products of amoxicillin trihydrate immediate-release preparations containing amoxicillin as the single active pharmaceutical ingredient at dose strengths of 875 mg or less, provided (a) only the excipients listed in this monograph are used, and only in their usual amounts, (b) the biowaiver study is performed according to the World Health Organization-, U.S. Food and Drug Administration-, or European Medicines Agency-recommended method using the innovator as the comparator, and (c) results comply with criteria for "very rapidly dissolving" or "similarly rapidly dissolving." Products containing other excipients and those containing more than 875 mg amoxicillin per unit should be subjected to an in vivo BE study. Copyright © 2017 American Pharmacists Association®.

    Oneal, Brent J; Reeb, Roger N; Korte, John R; Butter, Eliot J

    2006-01-01

    Since the publication of Lovaas' (1987) impressive findings, there has been a proliferation of home-based behavior modification programs for autistic children. Parents and other paraprofessionals often play key roles in the implementation and monitoring of these programs. The Behavioral Summarized Evaluation (BSE) was developed for professionals and paraprofessionals to use in assessing the severity of autistic symptoms over the course of treatment. This paper examined the psychometric properties of the BSE (inter-item consistency, factorial composition, convergent validity, and sensitivity to parents' perceptions of symptom change over time) when used by parents of autistic youngsters undergoing home-based intervention. Recommendations for future research are presented.

    Full Text Available The paper deals with the concept of data mining whereby the data resources can be fetched and accessed accordingly with reduced time complexity. Resource sharing is an important aspect in the field ofinformation science. The retrieval techniques are pointed out based on the ideas of binary search tree, Gantt chart, text summarization. A theorem has been cited regarding the summation of total length ofcodes of each leaf search term. Summarization is a hard problem of Natural Language Processing because, to do it properly, one has to really understand the point of a text. This requires semantic analysis, discourse processing, and inferential interpretation (grouping of the content using world knowledge. The last step, especially, is complex, because systems without a great deal of worldknowledge simply cannot do it. Therefore, attempts so far of erforming true abstraction--creating abstracts as summaries--have not been very successful. Fortunately, however, an approximationcalled extraction is more feasible today. To create an extract, a system need simply to identify the most important/topical/central topic(s of the text, and return them to the reader. Although the summary is not necessarily coherent, the reader can form an opinion of the content of the original. Most automated summarization systems today produce extracts only. Another purpose of this paper is to addresses the problem of information discovery in large collections of text. For users, one of the key problems in working with such collections is determining where to focus their attention. Textdocuments often contain valuable structured data that is hidden in regular English sentences. This data is best exploited if available as a relational table that we could use for answering precise queries or for running data mining tasks. We explore a technique for extracting such tables from document collections that requires only a handful of training examples from users. In this paper we have

    Mendelian randomization is the use of genetic variants as instrumental variables to estimate causal effects of risk factors on outcomes. The total causal effect of a risk factor is the change in the outcome resulting from intervening on the risk factor. This total causal effect may potentially encompass multiple mediating mechanisms. For a proposed mediator, the direct effect of the risk factor is the change in the outcome resulting from a change in the risk factor keeping the mediator constant. A difference between the total effect and the direct effect indicates that the causal pathway from the risk factor to the outcome acts at least in part via the mediator (an indirect effect). Here, we show that Mendelian randomization estimates of total and direct effects can be obtained using summarized data on genetic associations with the risk factor, mediator, and outcome, potentially from different data sources. We perform simulations to test the validity of this approach when there is unmeasured confounding and/or bidirectional effects between the risk factor and mediator. We illustrate this method using the relationship between age at menarche and risk of breast cancer, with body mass index (BMI) as a potential mediator. We show an inverse direct causal effect of age at menarche on risk of breast cancer (independent of BMI) and a positive indirect effect via BMI. In conclusion, multivariable Mendelian randomization using summarized genetic data provides a rapid and accessible analytic strategy that can be undertaken using publicly-available data to better understand causal mechanisms.

  3. Training in summarizing notes: Effects of teaching students a self-regulation study strategy in science learning

    Science.gov (United States)

    Nebres, Michelle

    The last two decades of national data assessments reveal that there has been a sharp decline in nationwide standardized test scores. International assessment data show that in 2012 a very low amount of American students were performing at proficiency or above in science literacy. Research in science literacy education suggests that students benefit most when they are self-regulated (SR) learners. Unfortunately, SR poses a challenge for many students because students lack these skills. The effects of having learned few SR strategies at an early age may lead to long term learning difficulties--preventing students from achieving academic success in college and beyond. As a result, some researchers have begun to investigate how to best support students' SR skills. In order for studying to be successful, students need to know which SR study strategies to implement. This can be tricky for struggling students because they need study strategies that are well defined. This needs to be addressed through effective classroom instruction, and should be addressed prior to entering high school in order for students to be prepared for higher level learning. In this study, students underwent a treatment in which they were taught a SR study strategy called summarizing notes. A crossover repeated measures design was employed to understand the effectiveness of the treatment. Results indicated a weak, but positive correlation between how well students summarized notes and how well they performed on science tests. Self-regulation skills are needed because these are the types of skills young adults will use as they enter the workforce. As young adults began working in a professional setting, they will be expected to know how to observe and become proficient on their own. This study is pertinent to the educational field because it is an opportunity for students to increase SR, which affords students with the skills needed to be a lifelong learner.

  4. NTP-CERHR monograph on the potential human reproductive and developmental effects of hydroxyurea.

    2008-10-01

    The National Toxicology Program (NTP) Center for the Evaluation of Risks to Human Reproduction (CERHR) conducted an evaluation of the potential for hydroxyurea to cause adverse effects on reproduction and development in humans. Hydroxyurea is a drug used to treat cancer, sickle cell disease, and thalassemia. It is the only treatment for sickle cell disease in children, aside from blood transfusion and, in severe cases, hematopoietic stem cell transplantation. Hydroxyurea is FDA-approved for use in adults with sickle cell anemia to reduce the frequency of painful crises and the need for blood transfusions. Hydroxyurea may be given to children and adults with sickle cell disease for an extended period of time or for repeated cycles of therapy. Treatment with hydroxyurea is associated with known side effects such as cytotoxicity and myelosuppression, and hydroxyurea is genotoxic (can damage DNA). CERHR selected hydroxyurea for evaluation because of: its increasing use for treatment of sickle cell disease in children and adults, knowledge that it inhibits DNA synthesis and is cytotoxic, and published evidence of reproductive and developmental toxicity in rodents. The results of this evaluation are published in the NTP-CERHR Monograph on Hydroxyurea, which includes the NTP Brief and Expert Panel Report on the Reproductive and Developmental Toxicity of Hydroxyurea. Additional information related to the evaluation process, including public comments received on the draft NTP Brief and the final expert panel report, are available on the CERHR website (http:// cerhr.niehs.nih.gov/). See hydroxyurea under "CERHR Chemicals" on the homepage or go directly to http://cerhr.niehs.nih.gov/chemicals/hydroxyurea/hydroxyurea-eval.html). The NTP reached the following conclusions on the possible effects of exposure to hydroxyurea on human reproduction or development. The possible levels of concern, from lowest to highest, are negligible concern, minimal concern, some concern, concern

    2012-12-01

    The present monograph reviews data relevant to applying the biowaiver procedure for the approval of immediate release (IR) multisource solid dosage forms containing amodiaquine hydrochloride (ADQ) as the single active pharmaceutical ingredient (API). Both biopharmaceutical and clinical data of ADQ were assessed. Solubility studies revealed that ADQ meets the "highly soluble" criteria according to World Health Organization (WHO) and European Medicines Agency (EMA) but fails to comply with the United States Food and Drug Administration (US FDA) specifications. Although metabolism hints at high permeability, available permeability data are too scanty to classify ADQ inequivocably as a Class I drug substance. According to WHO and EMA guidances, ADQ would be conservatively categorized as a Class III drug, whereas according to the US FDA specifications, it would fall into Class IV. ADQ has a wide therapeutic index. Furthermore, no cases of bioinequivalent products have been reported in the open literature. As risks associated with biowaiving appear minimal and requirements for "highly soluble" API are met in the WHO and EMA jurisdictions, the biowaiver procedure can be recommended for bioequivalence (BE) testing of multisource IR products containing ADQ as the only API, provided the test product contains excipients used in ADQ products approved in International Conference of Harmonisation and associated countries, and in similar amounts. Furthermore, both comparator and test should conform to "very rapidly dissolving" product criteria (≥85% dissolution of the API in 15 min at pH 1.2, 4.5, and 6.8) and the labeling should specify that the product not be coadministered with high-fat meals. If the comparator and/or test product fails to meet these criteria, BE needs to be established by pharmacokinetic studies in humans.

  6. Prevalence of genotoxic chemicals among animal and human carcinogens evaluated in the IARC Monograph Series.

    Bartsch, H; Malaveille, C

    1989-06-01

    To determine whether genotoxic and non-genotoxic carcinogens contribute similarly to the cancer burden in humans, an analysis was performed on agents that were evaluated in Supplements 6 and 7 to the IARC Monographs for their carcinogenic effects in humans and animals and for the activity in short-term genotoxicity tests. The prevalence of genotoxic carcinogens on four groups of agents, consisting of established human carcinogens (group 1, n = 30), probable human carcinogens (group 2A, n = 37), possible human carcinogens (group 2B, n = 113) and on agents with limited evidence of carcinogenicity in animals (a subset of group 3, n = 149) was determined. A high prevalence in the order of 80 to 90% of genotoxic carcinogens was found in each of the groups 1, 2A and 2B, which were also shown to be multi-species/multi-tissues carcinogens. The distribution of carcinogenic potency in rodents did not reveal any specific characteristic of the human carcinogens in group 1 that would differentiate them from agents in groups 2A, 2B and 3. The results of this analysis indicate that (a) an agent with unknown carcinogenic potential showing sufficient evidence of activity in in vitro/in vivo genotoxicity assays (involving as endpoints DNA damage and chromosomal/mutational damage) may represent a hazard to humans; and b) an agent showing lack of activity in this spectrum of genotoxicity assays should undergo evaluation for carcinogenicity by rodent bioassay, in view of the present lack of validated short-term tests for non-genotoxic carcinogens. Overall, this analysis implies that genotoxic carcinogens add more to the cancer burden in man than non-genotoxic carcinogens. Thus, identification of such genotoxic carcinogens and subsequent lowering of exposure will remain the main goal for primary cancer prevention in man.

  8. Dimensionless parameters to summarize the influence of microbial growth and inhibition on the bioremediation of groundwater contaminants.

    Mohamed, M; Hatfield, K

    2011-09-01

    Monod expressions are preferred over zero- and first-order decay expressions in modeling contaminants biotransformation in groundwater because they better represent complex conditions. However, the wide-range of values reported for Monod parameters suggests each case-study is unique. Such uniqueness restricts the usefulness of modeling, complicates an interpretation of natural attenuation and limits the utility of a bioattenuation assessment to a small number of similar cases. In this paper, four Monod-based dimensionless parameters are developed that summarize the effects of microbial growth and inhibition on groundwater contaminants. The four parameters represent the normalized effective microbial growth rate (η), the normalized critical contaminant/substrate concentration (S*), the critical contaminant/substrate inhibition factor (N), and the bioremediation efficacy (η*). These parameters enable contaminated site managers to assess natural attenuation or augmented bioremediation at multiple sites and then draw comparisons between disparate remediation activities, sites and target contaminants. Simulations results are presented that reveal the sensitivity of these dimensionless parameters to Monod parameters and varying electron donor/acceptor loads. These simulations also show the efficacy of attenuation (η*) varying over space and time. Results suggest electron donor/acceptor amendments maintained at relative concentrations S* between 0.5 and 1.5 produce the highest remediation efficiencies. Implementation of the developed parameters in a case study proves their usefulness.

    The responses of intestinal tissues to ionizing radiation can be described by comparing irradiated cell populations qualitatively or quantitatively with corresponding controls. This paper describes quantitative data obtained from resin-embedded sections of neutron-irradiated mouse small intestine at different times after treatment. Information is collected by counting cells or structures present per complete circumference. The data are assessed by using standard statistical tests, which show that early mitotic arrest precedes changes in goblet, absorptive, endocrine and stromal cells and a decrease in crypt numbers. The data can also produce ratios of irradiated:control figures for cells or structural elements. These ratios, along with tissue area measurements, can be used to summarize the structural damage as a composite graph and table, including a total figure, known as the Morphological Index. This is used to quantify the temporal response of the wall as a whole and to compare the effects of different qualities of radiation, here X-ray and cyclotron-produced neutron radiations. It is possible that such analysis can be used predictively along with other reference data to identify the treatment, dose and time required to produce observed tissue damage. (author).

    Miraculin, a taste-modify glycoprotein, is first discovered in the miracle fruit (Synsepalum dulcificum). Miraculin is made up of 191 amino acids, and the main active forms of it are dimmers and tetramers, in which His-30 and His-60 are the active centers. Cys also plays a role in its structure forming and folding to some degree. The glycosylation sites of miraculin are Asn-42 and Asn-186. Miraculin itself does not taste sweet, and in the neutral pH condition it does not show any activity either. But under acidic condition, it can bring about an activity of changing food from sour to sweet, which may last for 1-2 h. On the side, miraculin can increase the sensitivity of diabetic animals to insulin. The latest preparation methods of miraculin are direct extraction from Synsepalum dulcificum and expressing in transgenic plants or microbiology. In this paper, we summarized the miraculin structure, function and preparation methods in many latest researches.%神秘果素(miraculin,MIR)是在神秘果中(Synsepalum dulcificum)发现的一种变味糖蛋白,又称为变味魔术师。神秘果素由191个氨基酸组成,其主要活性形式为二聚体和四聚体,His-30和His-60是这个糖蛋白的活性中心位点,Asn-42和Asn-186是神秘果素的糖基化位点,Cys对蛋白的结构和折叠也有一定的影响。神秘果素本身并没有甜味,在中性条件下不表现出活性,但是在酸性条件下能够产生让酸的食物变甜的活性,并且这种影响能够持续一段时间(1~ 2 h);另一方面,神秘果素能够在一定程度上提高糖尿病动物对胰岛素的敏感性。最新的制备方法是通过从神秘果中直接提取、转基因到植物中和在微生物中进行表达等方法。综述了神秘果素的结构、功能和制备方法等方面的研究进展。

First, students need to master the intellectual skills of the humanities in order to provide critical analysis of social situations. Secondly, students need to know that, as western scholars, they are as much part of any postcolonial problem as those in power, and therefore need to develop good reflective skills and to learn to think ‘otherwise’.

  1. Screening assays for carcinogenic agents and mixtures: an appraisal based on data in the IARC Monograph series.

    Science.gov (United States)

    Bartsch, H; Malaveille, C

    1990-01-01

    To determine whether genotoxic and non-genotoxic carcinogens contribute similarly to the cancer burden in humans and which types of short-term test are more relevant for predicting human hazards, an analysis was performed on agents that were evaluated in IARC Monographs Supplements 6 and 7 for their carcinogenic effects in humans and animals and for activity in short-term genotoxicity tests. The prevalence of genotoxicity among four groups of agents, consisting of established human carcinogens (group 1, n = 30), probable human carcinogens (group 2A, n = 37), possible human carcinogens (group 2B, n = 113) and agents with limited evidence of carcinogenicity in animals (a subset of group 3, n = 66) was determined. Each of the groups 1, 2A and 2B contained a high proportion (80-90%) of genotoxic carcinogens, which were also multi-species or multi-tissue carcinogens. The distribution of carcinogenic potency in rodents did not reveal any specific characteristic of the human carcinogens in group 1 that would differentiate them from agents in groups 2A, 2B and many in group 3. Although limited by the data-base available through the Monographs series, this analysis implies that genotoxic carcinogens add more to the human cancer burden than non-genotoxic carcinogens. Thus, the continued use of in vitro/in vivo short-term tests, involving as endpoints DNA chromosomal or mutational damage, to identify genotoxic carcinogens or in the isolation of carcinogenic components in complex mixtures is fully justified. It is concluded that (a) an agent or complex mixture with unknown carcinogenic potential showing sufficient evidence of activity in genotoxicity assays in vitro or in vivo is likely to represent a hazard to humans and (b) an agent or complex mixture showing lack of activity in this spectrum of genotoxicity assays should undergo evaluation for carcinogenicity for rodent bioassay, in view of the present lack of validated short-term tests for non-genotoxic carcinogens.

    The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

    We summarize recent work on the classification of modular invariant partition functions that can be obtained with simple currents in theories with a center (Z_p)^k with p prime. New empirical results for other centers are also presented. Our observation that the total number of invariants is monodromy-independent for (Z_p)^k appears to be true in general as well.

    2014-01-01

    Perihilar cholangiocarcinoma, which is a rare primary malignancy, originates from the epithelial cells of the bile duct. Usually invading the periductal tissues and the lymph nodes, perihilar cholangiocarcinoma is commonly diagnosed in the advanced stage of the disease and has a dismal prognosis. Currently, complete hepatectomy is the primary therapy for curing this disease. Perioperative assessment and available surgical procedures can be considered for achieving a negative margin resection, which is associated with long-term survival and better quality of life. For patients with unresectable cholangiocarcinoma, several palliative treatments have been demonstrated to produce a better outcome; and liver transplantation for selected patients with perihilar cholangiocarcinoma is promising and desirable. However, the role of palliative treatments and liver transplantation was controversial and requires more evidence and substantial validity from multiple institutions. In this article, we summarize the data from multiple institutions and discuss the resectability, mortality, morbidity and outcome with different approaches.

    2011-08-01

    The United States Pharmacopeia (USP) monograph for unfractionated heparin (UFH) was revised in October 2009. This revision was anticipated, based upon in vitro tests, to reduce UFH potency by approximately 10%. To study the potential in vivo consequences of the monograph change, we evaluated activated partial thromboplastin time (aPTT) and activated clotting time (ACT) responses in animals. Female mini-pigs and monkeys (n=8/species) were administered intravenously 60, 54, 48, or 42 U/kg and 50, 45, 40, or 35 U/kg "old" (pre-USP revision) UFH, respectively, in a Williams 4×4 crossover design. Blood samples for aPTT and ACT were collected at 15 min after dosing. The same study design was then repeated using "new" (post-USP revision) UFH. Mean "new" UFH aPTT and ACT values were generally lower than those for "old" UFH although individual animal responses varied considerably. The aPTT and ACT response was generally dose-proportional for both "old" and "new" UFH. These studies indicate that the USP monograph alteration for UFH may result in a modest reduction in the anticoagulant response across a population, but the variability in animal responses underscores the importance of individualization of clinical UFH dosing and the importance of anticoagulant test monitoring.

  12. NTP-CERHR Monograph on the Potential Human Reproductive and Developmental Effects of 1-Bromopropane (1-BP).

    Science.gov (United States)

    2003-10-01

    The National Toxicology Program (NTP) Center for the Evaluation of Risks to Human Reproduction (CERHR) conducted an evaluation of the potential for 1-bromopropane to cause adverse effects on reproduction and development in humans. 1-Bromopropane was selected for evaluation due to recent consideration of 1-bromopropane as a replacement chemical for hydrochlorofluorocarbons and chlorinated solvents. 1-Bromopropane is used in spray adhesives and in cleaning metal and electronic components; as a solvent for fats, waxes, or resins; and as an intermediate in the synthesis of pharmaceuticals, insecticides, quaternary ammonium compounds, flavors, or fragrances. The results of this evaluation on 1-brompropane are published in a NTP-CERHR monograph which includes: 1) the NTP Brief, 2) the Expert Panel Report on the Reproductive and Developmental Toxicity of 1-Bromopropane, and 3) public comments received on the Expert Panel Report. As stated in the NTP Brief, the NTP reached the following conclusions regarding the possible effects of exposure to 1-bromopropane on human development and reproduction. No data were available on 1-bromopropane exposures in the general US population. Therefore, conclusions were based on the available occupational exposure data and on studies in humans and laboratory animals. First, there is serious concern for reproductive and developmental effects at the upper end of the human occupational exposure range (18-381 ppm). Adverse developmental and/or reproductive effects have been reported in animal studies at exposure levels of >/=200 ppm. Second, there is minimal concern for reproductive and developmental effects when humans are exposed at the lower end of the human occupational exposure range (0.04-0.63 ppm). This level is at least 300- fold lower than the no effect level identified from reproductive studies in laboratory animals. These conclusions are based upon limited occupational inhalation exposure data. It is likely that worker exposures

    Fogazzi, G B

    2007-01-01

    This monograph, published in 1953, describes the findings observed by the author in a cohort of patients affected by diabetes mellitus and renal disease. From a pathological standpoint, the typical renal lesion is represented by ''nodular intercapillary glomerulosclerosis'', which is present in 8 out of 20 patients at postmortem. Marked proteinuria and edema are the most typical clinical features. Urinary sediment examination is the only test allowing to differentiate diabetic nephropathy from other glomerular diseases. In the initial phases, the glomerular filtration rate is increased rather than reduced. The evolution is almost invariably towards end-stage renal disease, and a hypoglucidic diet and insulin are the only therapeutic modalities available. Today this work shows us, on the one hand, how many uncertainties still existed about diabetic nephropathy 17 years after its first description by Kimmelstiel and Wilson in 1936. On the other hand, it shows how much relevant and still valid information was already known at the time. Luigi Scapellato, who is almost completely forgotten today, began his career at the Clinica Medica of the University of Rome under the guidance of Cesare Frugoni (1881-1978). In 1959, he moved to Syracuse (Sicily) to work as director of the internal medicine unit of the ''Umberto I'' Hospital. In April 1957 he was among the 13 founders of the Italian Society of Nephrology.

    The ¹H nuclear magnetic resonance (NMR) acceptance criteria in the new heparin US Pharmacopeia (USP) monograph do not take into account potential structural modifications responsible for any extra signals observed in ¹H NMR spectra, some purified heparins may be non-compliant under the proposed new USP guidelines and incorrectly classified as unsuitable for pharmaceutical use. Heparins from the "ES" source, containing an extra signal at 2.18 ppm, were depolymerized under controlled conditions using heparinases I, II, and III. The oligosaccharides responsible for the 2.18 ppm signal were enriched using orthogonal chromatographic techniques. After multiple purification steps, we obtained an oligosaccharide mixture containing a highly enriched octasaccharide bearing the structural modification responsible for the extra signal. Following heparinase I depolymerization, a pure tetrasaccharide containing the fingerprint structural modification was isolated for full structural determination. Using 1D and 2D ¹H NMR spectroscopy, the structural moiety responsible for the extra signal at 2.18 ppm was identified as an acetyl group on the heparin backbone, most likely resulting from a very minor manufacturing process side reaction that esterifies the uronic acid at position 3. Such analytical peculiarity has always been present in this heparin source and it was used safety over the years. Copyright © 2012 Elsevier B.V. All rights reserved.

  6. 60 YEARS OF NEUROENDOCRINOLOGY: Celebrating the brain's other output-input system and the monograph that defined neuroendocrinology.

    Science.gov (United States)

    Coen, Clive W

    2015-08-01

    The brain's unimaginably complex operations are expressed in just two types of output: muscle activity and hormone release. These are the means by which the brain acts beyond its bony casing. Muscle-mediated actions (such as speaking, writing, pupillary reflexes) send signals to the outside world that may convey thoughts, emotions or evidence of neurological disorder. The outputs of the brain as a hormone secreting gland are usually less evident. Their discovery required several paradigm shifts in our understanding of anatomy. The first occurred in 1655. Exactly 300 years later, Geoffrey Harris' monograph Neural control of the pituitary gland launched the scientific discipline that is now known as neuroendocrinology. His hypotheses have stood the test of time to a remarkable degree. A key part of his vision concerned the two-way 'interplay between the central nervous system and endocrine glands'. Over the past 60 years, the importance of this reciprocity and the degree to which cerebral functions are influenced by the endocrine environment have become increasingly clear. © 2015 Society for Endocrinology.

    Full Text Available Introduction. Bird cherry Padus avium Mill, Rosaceae, is widespread in Ukraine, especially in forests and forest-steppe areas. Bird cherry fruits have long been used in medicine and is a valuable medicinal raw materials. They stated to posess astringent, anti-inflammatory, phytoncidal properties. Bird cherry fruits are included in the USSR Pharmacopoeia IX ed., The State Pharmacopoeia of the Russian Federation, The State Pharmacopoeia of Republic of Belarus. In Ukraine there are no contemporary normative documents for this medicinal plant material, therefore it is the actual to develop projects in the national monographs "dry bird cherry fruit" and "fresh bird cherry fruit" to be included in the State Pharmacopoeia of Ukraine. According to European Pharmacopoeia recommendation method of thin-layer chromatography (TLC is prescribed only for the identification of the herbal drug. The principles of thin-layer chromatography and application of the technique in pharmaceutical analysis are described in State Pharmacopoeia of Ukraine. As it is effective and easy to perform, and the equipment required is inexpensive, the technique is frequently used for evaluating medicinal plant materials and their preparations. The TLC is aimed at elucidating the chromatogram of the drug with respect to selected reference compounds that are described for inclusion as reagents. Aim of this study was to develop methods of qualitative analysis of bird cherry fruits for a monograph in the State Pharmacopoeia of Ukraine (SPU. Materials and Methods. The object of our study was dried bird cherry fruits (7 samples and fresh bird cherry fruits (7 samples harvested in 2013-2015 in Kharkiv, Poltava, Luhansk, Sumy, Lviv, Mykolaiv regions and the city Mariupol. Samples were registered in the department of SPU State Enterprise "Pharmacopeia center". In accordance with the Ph. Eur. and SPU requirements in "identification C" determination was performed by TLC.

    Literature data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate release (IR) solid oral dosage forms containing amitriptyline hydrochloride are reviewed. Its therapeutic uses, its pharmacokinetic properties, the possibility of excipient interactions and reported BE/bioavailability (BA) problems are also taken into consideration. Literature data indicates that amitriptyline hydrochloride is a highly permeable active pharmaceutical ingredient (API). Data on the solubility according to the current Biopharmaceutics Classification System (BCS) were not fully available and consequently amitriptyline hydrochloride could not be definitively assigned to either BCS Class I or BCS Class II. But all evidence taken together, a biowaiver can currently be recommended provided that IR tablets are formulated with excipients used in existing approved products and that the dissolution meets the criteria defined in the Guidances.

  11. Current ornithology

    CERN Document Server

    1983-01-01

    The appearance of the first volume of a projected series is the occasion for comment on scope, aims, and genesis of the work. The scope of Current Ornithology is all of the biology of birds. Ornithology, as a whole-organism science, is concerned with birds at every level of bi­ ological organization, from the molecular to the community, at least from the Jurassic to the present time, and over every scholarly discipline in which bird biology is done; to say this is merely to expand a dic­ tionary definition of "ornithology. " The aim of the work, to be realized over several volumes, is to present reviews or position statements con­ cerning the active fields of ornithological research. The reviews will be relatively short, and often will be done from the viewpoint of a readily­ identified group or school. Such a work could have come into being at any time within the past fifty years, but that Current Ornithology appears now is a result of events that are only seven to eight years old. One important event wa...

  12. Summarizing EC50 estimates from multiple dose-response experiments: a comparison of a meta-analysis strategy to a mixed-effects model approach.

    2014-05-01

    Dose-response studies are performed to investigate the potency of a compound. EC50 is the concentration of the compound that gives half-maximal response. Dose-response data are typically evaluated by using a log-logistic model that includes EC50 as one of the model parameters. Often, more than one experiment is carried out to determine the EC50 value for a compound, requiring summarization of EC50 estimates from a series of experiments. In this context, mixed-effects models are designed to estimate the average behavior of EC50 values over all experiments by considering the variabilities within and among experiments simultaneously. However, fitting nonlinear mixed-effects models is more complicated than in a linear situation, and convergence problems are often encountered. An alternative strategy is the application of a meta-analysis approach, which combines EC50 estimates obtained from separate log-logistic model fitting. These two proposed strategies to summarize EC50 estimates from multiple experiments are compared in a simulation study and real data example. We conclude that the meta-analysis strategy is a simple and robust method to summarize EC50 estimates from multiple experiments, especially suited in the case of a small number of experiments.

  13. Biowaiver monographs for immediate-release solid oral dosage forms: ketoprofen.

    Literature and experimental data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate-release (IR) solid oral dosage forms containing ketoprofen are reviewed. Ketoprofen's solubility and permeability, its therapeutic use and therapeutic index, pharmacokinetic properties, data related to the possibility of excipient interactions, and reported BE/bioavailability (BA)/dissolution data were taken into consideration. The available data suggest that according to the current Biopharmaceutics Classification System (BCS) and all current guidances, ketoprofen is a weak acid that would be assigned to BCS Class II. The extent of ketoprofen absorption seems not to depend on formulation or excipients, so the risk of bioinequivalence in terms of area under the curve is very low, but the rate of absorption (i.e., BE in terms of peak plasma concentration, C(max) ) can be altered by formulation. Current in vitro dissolution methods may not always reflect differences in terms of C(max) for BCS Class II weak acids; however, such differences in absorption rate are acceptable for ketoprofen with respect to patient risks. As ketoprofen products may be taken before or after meals, the rate of absorption cannot be considered crucial to drug action. Therefore, a biowaiver for IR ketoprofen solid oral dosage form is considered feasible, provided that (a) the test product contains only excipients present also in IR solid oral drug products containing ketoprofen, which are approved in International Conference on Harmonisation or associated countries, for instance, as presented in this paper; (b) both the test drug product and the comparator dissolve 85% in 30 min or less in pH 6.8 buffer; and (c) test product and comparator show dissolution profile similarity in pH 1.2, 4.5, and 6.8. When one or more of these conditions are not fulfilled, BE should be established in vivo.

    Literature and experimental data relevant to the decision to allow a waiver of in vivo bioequivalence testing for the approval of immediate release (IR) solid oral dosage forms containing ranitidine hydrochloride are reviewed. According to the current Biopharmaceutics Classification System (BCS), ranitidine hydrochloride should be assigned to Class III. However, based on its therapeutic and therapeutic index, pharmacokinetic properties and data related to the possibility of excipient interactions, a biowaiver can be recommended for IR solid oral dosage forms that are rapidly dissolving and contain only those excipients as reported in this study.

    Chronic lymphocytic leukemia (CLL) is the most frequently diagnosed hematologic malignancy in the United States. Although several features can be useful in the diagnosis of CLL, the most important is the immunophenotype.Two staging systems--the Binet system and the Rai classification--are used to assess risk. After diagnosis, the first major therapeutic decision is when to initiate therapy, as a watchful waiting approach is often appropriate for patients with asymptomatic disease. Once a patient has met the criteria for treatment, the choice of therapy is the next major decision. Younger patients (<65 years) often receive more aggressive treatment that typically consists of cytotoxic chemotherapy. There is a great unmet need concerning treatment of older patients with CLL, who often present with more comorbid conditions that can decrease their ability to tolerate particular regimens. The current standard of care for older patients with CLL is rituximab plus chlorambucil. The concept of targeted agents is currently an area of intense interest in CLL. The Bruton’s tyrosine kinase inhibitor ibrutinib is the targeted agent that is furthest along in clinical development. It is associated with an overall survival rate of 83%. Idelalisib targets the phosphatidyl inositol 3-kinase and is under evaluation in pivotal trials. Targeted agents offer much promise in terms of efficacy, toxicity, and oral availability. They will change the management of patients with CLL.

    2014-02-01

    Literature data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate-release (IR) solid oral dosage forms containing bisoprolol as the sole active pharmaceutical ingredient (API) are reviewed. Bisoprolol is classified as a Class I API according to the current Biopharmaceutics Classification System (BCS). In addition to the BCS class, its therapeutic index, pharmacokinetic properties, data related to the possibility of excipient interactions, and reported BE/bioavailability problems are taken into consideration. Qualitative compositions of IR tablet dosage forms of bisoprolol with a marketing authorization (MA) in ICH (International Conference on Harmonisation) countries are tabulated. It was inferred that these tablets had been demonstrated to be bioequivalent to the innovator product. No reports of failure to meet BE standards have been made in the open literature. On the basis of all these pieces of evidence, a biowaiver can currently be recommended for bisoprolol fumarate IR dosage forms if (1) the test product contains only excipients that are well known, and used in normal amounts, for example, those tabulated for products with MA in ICH countries and (2) both the test and comparator dosage form are very rapidly dissolving, or, rapidly dissolving with similarity of the dissolution profiles demonstrated at pH 1.2, 4.5, and 6.8. © 2013 Wiley Periodicals, Inc. and the American Pharmacists Association.

  2. Current Issues in Cosmology

    Energy Technology Data Exchange (ETDEWEB)

    2007-02-07

    These colloquium proceedings will be valuable, the blurb says, for graduate students and researchers in cosmology and theoretical astrophysics. Specifically, the book 'looks at both the strengths and weaknesses of the current big bang model in explaining certain puzzling data' and gives a 'comprehensive coverage of the expanding field of cosmology'. The reality is rather different. Conference proceedings rarely compare in value with a solid monograph or good review articles, and Current Issues in Cosmology is no exception. The colloquium was convened by the two editors, who have both long harboured doubts about the big bang, and was held in Paris in June 2004. The proceedings contain 19 presented papers and relatively brief summary comments by four panel speakers. The questions and answers at the end of each talk and a general discussion at the end were recorded and transcribed but contain little of interest. The nature of the colloquium is indicated by panellist Francesco Bertola's comment: 'While in the 1950s it was possible to speak of rival theories in cosmology, now the big-bang picture has no strong rivals. This is confirmed by the fact that out of 1500 members of the IAU Division VIII (Galaxies and the Universe) only a dozen, although bright people, devote their time to the heterodox views.' This was largely a platform for them to give their views. At least half of the dozen, all the 'usual suspects', were present: Geoffery and Margaret Burbidge, Jayant Narlikar, Halton Arp, Chandra Wickramasinghe and, in spirit only but playing a role somewhat like the ghost of Hamlet's father, the late Fred Hoyle. Doubters presented 12 of the 19 papers. Orthodoxy should certainly be challenged and the sociology of science questioned, but I found two main problems with this book. The papers putting the orthodox view are too short, even perfunctory. The most that a serious graduate student would get out of them is a reference

  3. Pierre Janet's addition to Charles-Hubert-Antoine Despine's "Old but very curious" Estelle L'Hardy monograph.

    2008-01-01

    In the magisterial book The Discovery of the Unconscious, Ellenberger (1970) showed a keen appreciation for practitioners of many schools of therapy, including those who practiced animal magnetism (hypnotism). He credited Despine and Janet for their contributions to dynamic psychiatry and documented Janet's intellectual debt to Despine's successful magnetic treatment of 11-year-old Estelle's hysteria (dissociative disorder). No scholarship, however, has identified Janet's unique addition to Despine's 1838/1839 monograph--written decades before Janet's birth. Supplementing Despine's account of Estelle's minor fall that precipitated her paralysis, Janet reported that Estelle disobeyed her mother by quarreling with a friend, soiled her frock, experienced fright and shame, and sought to conceal everything from her mother. The author argues (a) that Despine knew yet wisely excluded Janet's data lest Estelle's family prevent his publishing the case; (b) that Janet's published data about the youngster's fall reached him through a professional network; and (c) that Janet's plausible addition comports well with his theoretical psychology of action--used in this article to explain the fine-grained parsing of Estelle's inner processes during the milliseconds of her fall: her vehement affect substituted for adaptive behavior. This article deepens the understanding of the Despin-Janet connection; maintains that Janet's addition deserves a place in the tradition of the medical case report; encourages trauma specialists to become familiar with their pioneers; and highlights the clinical continuity from Janet's affirmation of Despine's pioneering treatment strategies with the chronically traumatized to contemporary treatment for the same population, conceptualized along Janetian lines.

    Literature data are reviewed on the properties of acetaminophen (paracetamol) related to the biopharmaceutics classification system (BCS). According to the current BCS criteria, acetaminophen is BCS Class III compound. Differences in composition seldom, if ever, have an effect on the extent of absorption. However, some studies show differences in rate of absorption between brands and formulations. In particular, sodium bicarbonate, present in some drug products, was reported to give an increase in the rate of absorption, probably caused by an effect on gastric emptying. In view of Marketing Authorizations (MAs) given in a number of countries to acetaminophen drug products with rapid onset of action, it is concluded that differences in rate of absorption were considered therapeutically not relevant by the Health Authorities. Moreover, in view of its therapeutic use, its wide therapeutic index and its uncomplicated pharmacokinetic properties, in vitro dissolution data collected according to the relevant Guidances can be safely used for declaring bioequivalence (BE) of two acetaminophen formulations. Therefore, accepting a biowaiver for immediate release (IR) acetaminophen solid oral drug products is considered scientifically justified, if the test product contains only those excipients reported in this paper in their usual amounts and the test product is rapidly dissolving, as well as the test product fulfils the criterion of similarity of dissolution profiles to the reference product.

    2011-01-01

    Full Text Available Extractive multidocument summarization is modeled as a modified p-median problem. The problem is formulated with taking into account four basic requirements, namely, relevance, information coverage, diversity, and length limit that should satisfy summaries. To solve the optimization problem a self-adaptive differential evolution algorithm is created. Differential evolution has been proven to be an efficient and robust algorithm for many real optimization problems. However, it still may converge toward local optimum solutions, need to manually adjust the parameters, and finding the best values for the control parameters is a consuming task. In the paper is proposed a self-adaptive scaling factor in original DE to increase the exploration and exploitation ability. This paper has found that self-adaptive differential evolution can efficiently find the best solution in comparison with the canonical differential evolution. We implemented our model on multi-document summarization task. Experiments have shown that the proposed model is competitive on the DUC2006 dataset.

    2010-06-01

    Full Text Available Over the last 30 years, the pathogenesis of osteomyelitis has almost been totally elucidated, and many factors responsible for the persistence of this infection have been identified. Numerous antimicrobial agents with distinct spectrums of action, pharmacokinetics, and pharmacodynamics have been used in its treatment. Surgical techniques, including muscle grafts, the Ilizarov technique, and antibiotic bone cements, have been applied. However, bone infections are still a challenge. Despite the importance of isolation and identification of microorganisms to determine the antimicrobial treatment of bone infections, there are few systematic national studies about the etiological profile of these diseases. This article describes the current knowledge of osteomyelitis and summarizes published national data based on the experience of different Orthopedic and Traumatology Services. In general, S. aureus was described as an important etiological agent; however, the difference in design of national studies makes a comparison between the prevalence of bone infection, the associated risk factors, and the different therapeutic approaches difficult. In conclusion, effort is necessary in order to stimulate systematic national studies in different Orthopedics and Traumatology Services to obtain a better consensus on preventive measures and therapies of bone infections.

    2008-01-01

    Full Text Available Purpose: Chronic prostatitis (CP is a common condition. It causes significant suffering to the patients and constitutes a sizeable workload for the urologists. The purpose of this review is to describe the currently accepted concepts regarding the aspects of CP. Materials and Methods: Relevant papers on the epidemiology, etiology, diagnosis, evaluation and management of CP were identified through a search of MEDLINE using text terms "prostatitis", "chronic prostatitis" and "chronic pelvic pain syndrome". The list of articles thus obtained was supplemented by manual search of bibliographies of the identified articles and also by exploring the MEDLINE option "Related Articles". Results: The salient points of the relevant articles on each aspect of CP have been summarized in the form of a non-systematic narrative review. Conclusion: Chronic prostatitis is caused by a variety of infective and non-infective factors and is characterized by a rather long remitting and relapsing clinical course. The diagnosis is based on symptoms comprising pain and nonspecific urinary and/or ejaculatory disturbances and microbiological tests to localize bacteria and/or leucocytes in segmented urinary tract specimens. The contemporary classification was proposed by the National Institutes of Health/National Institute of Diabetes Digestive Kidney Diseases (NIH/NIDDK. National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI is the patient evaluation tool used extensively in clinical practice and research. Management should be individualized, multimodal and of an appropriate duration.

    Excess fat accumulates in the subcutaneous and visceral adipose tissue compartments. We tested the hypothesis that indicators of visceral adiposity, namely, waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR), are better predictors of stroke risk than body mass index (BMI). The association of BMI, WC, WHR, and WHtR with stroke was assessed in 31,201 men and 23,516 women, free of vascular disease at baseline, from the MOnica Risk, Genetics, Archiving and Monograph (MORGAM) study. During a mean follow-up of 11 years, 1130 strokes were recorded. Relative risks (95% CI) were calculated by Cox regression after stratification for center and adjustment for age, smoking, educational level, alcohol consumption, hypertension, diabetes, total cholesterol, high-density lipoprotein cholesterol, and BMI and model fit was assessed using log-likelihoods. BMI, WC, WHR, and WHtR were associated with the risk of stroke in men. After full adjustment including BMI, the relative risks for stroke remained significant for WC (1.19 [1.02 to 1.34] per 1 SD increase in WC), WHR (1.14 [1.03 to 1.26]), and WHtR (1.50 [1.28 to 1.77]). Among women, the extent of the associations with stroke risk was similar for WHtR (1.31 [1.04 to 1.65]), WC (1.19 [0.96 to 1.47]), and WHR (1.08 [0.97 to 1.22]). Further analyses by World Health Organization obesity categories showed that WC, WHR, and WHtR were associated with the risk of stroke also in lean men and women (BMI<25 kg/m2), independently of confounders, cardiovascular risk factors, and BMI. Indicators of abdominal adiposity, especially WHtR, are more strongly associated with stroke risk than BMI. These results emphasize the importance of measuring abdominal adiposity, especially in lean subjects.

    We release GeneBase 1.1, a local tool with a graphical interface useful for parsing, structuring and indexing data from the National Center for Biotechnology Information (NCBI) Gene data bank. Compared to its predecessor GeneBase (1.0), GeneBase 1.1 now allows dynamic calculation and summarization in terms of median, mean, standard deviation and total for many quantitative parameters associated with genes, gene transcripts and gene features (exons, introns, coding sequences, untranslated regions). GeneBase 1.1 thus offers the opportunity to perform analyses of the main gene structure parameters also following the search for any set of genes with the desired characteristics, allowing unique functionalities not provided by the NCBI Gene itself. In order to show the potential of our tool for local parsing, structuring and dynamic summarizing of publicly available databases for data retrieval, analysis and testing of biological hypotheses, we provide as a sample application a revised set of statistics for human nuclear genes, gene transcripts and gene features. In contrast with previous estimations strongly underestimating the length of human genes, a ‘mean’ human protein-coding gene is 67 kbp long, has eleven 309 bp long exons and ten 6355 bp long introns. Median, mean and extreme values are provided for many other features offering an updated reference source for human genome studies, data useful to set parameters for bioinformatic tools and interesting clues to the biomedical meaning of the gene features themselves.

    Tanii, 1985). It can react with DNA in vitro to produce a guanine derivative N7-(2-carbamoyl-2-hydroxyethyl)guanine(Gamboa da Costa et al., 2003; Segerback et al., 1995). In vivo, administration of acrylamide to rats and mice produces low levels of N7-(2-carbamoyl-2-hydroxyethyl)guanine (Gamboa da Costa et al., 2003; Segerback et al., 1995).Acrylamide induces a characteristic peripheral neurotoxicity in animals and man(Spencer and Schaumburg, 1974a, b, 1975). This toxicity manifests itself as a distal to proximal loss of nerve function and dying back of cells. Acrylamide also effects rodent reproduction, namely smaller litter size. At elevated acrylamide doses other reproductive effects are seen, likely as a consequence of the neurotoxicity. Acrylamide is carcinogenic in drinking water studies in laboratory rats (Friedman et al.,1995; Johnson et al., 1986). In male rats, it induces tumors of the tunica vaginalis testes and the thyroid, while in females, it induces mammary fibroadenomas and thyroid tumors(Friedman et al., 1995). The mechanism for this tumorigenicity is unclear, although interaction with the dopamine receptor has been postulated as well as genotoxicity (Tyland Friedman, 2003). If the mechanism were genotoxicity, then conversion of acrylamide to glycidamide is directly proportional to carcinogenic activity.Understanding the mechanism of tumorigenicity is important, since conventional risk assessment techniques place the order of magnitude of the risk at approximately 10-3 with exposures of 70 μg/ day.The relative contributions of acrylamide and glycidamide in the mode of action of acrylamide are the subject of debate and current research. Understanding the conversion of acrylamide to glycidamide and differences that may occur between species, exposure route, and dose are important considerations in assessing the risk of the possible effects of acrylamide exposures in the diet, in consumer products, and in the workplace.The primary objectives of this study

    Presently FAIR, the Facility for Antiproton and Ion Research, entered the final planning phase at GSI. The new accelerator facility requires precise devices for beam current measurements due to the large dynamics in beam intensities for the various synchrotrons, transport lines and storage rings. We report on the actual developments of beam diagnostic devices for the measurement of beam intensities ranging from 5 x 10{sup 11} uranium ions down to the detection of less than 10{sup 4} antiprotons. This contribution gives an overview of the planned instruments with a focus on non-intercepting beam current transformers, and summarizes the on-going development of a cryogenic current comparator.

  5. BOOK REVIEW: The Current Comparator

    Science.gov (United States)

    Petersons, Oskars

    1989-01-01

    This 120-page book is a concise, yet comprehensive, clearly-written and well-illustrated monograph that covers the subject matter from basic principles through design, construction and calibration details to the principal applications. The book will be useful, as a primer, to the uninitiated and, as a reference book to the practitioner involved with transformer-type ratio devices. The length of the book and the style of presentation will not overburden any informed reader. The described techniques and the cited references are primarily from the work at the National Research Council, Canada (NRC). Any omissions, however, are not serious with respect to coverage of the subject matter, since most of the development work has been done at NRC. The role of transformers and transformer-like devices for establishing accurate voltage and current ratios has been recognized for over half a century. Transformer techniques were much explored and developed in the fifties and sixties for accuracy levels suitable for standards laboratories. Three-winding voltage transformers were developed for scaling of impedances in connection with the calculable Thompson Lampard capacitor; three-winding current transformers or current comparators were initially explored for the calibration of current transformers and later for specialized impedance measurements. Extensive development of the current comparator and its applications has been and is still being conducted at the NRC by a team that was started and, until his retirement, led by N L Kusters. The team is now led by W J M Moore. He and P N Miljanic, the authors of this book, have had the principal roles in the development of the current comparator. It is fortunate for the field of metrology that considerabe resources and a talented group of researchers were available to do this development along with mechanisms that were available to transfer this technology to a private sector instrument manufacturer and, thus, disseminate it world wide

  1. Monograph: Concluding Remarks

    Directory of Open Access Journals (Sweden)

    Full Text Available Private investment in biomedical research has increased over the last few decades. At most places it has been welcomed as the next best thing to technology itself. There are significant costs involved too. Major areas of conflict of interest especially applicable to biomedical research have arisen, as academia interacts with industry. Pharma image stinks because of a number of errors of omission and commission. A recent example is suppression of negative findings about Bayer's Trasylol (Aprotinin and the marketing maneuvers of Eli Lilly's Xigris (rhAPC. A voluntary moratorium over pharma spending to pamper drug prescribers is necessary.The integrity of industry-sponsored clinical research has come under increasing scrutiny. The basic shizm is between the value system of a patient welfare driven professional and that of a profit driven industry . While one wants to avoid control but wants the dough, the other wants to exercise the control by supplying the dough. Clinical practice guidelines (CPG are considered important as they guide diagnostic/therapeutic regimen of a large number of medical professionals and hospitals and provide recommendations on drugs, dosages and criteria for selection. Besides clinical trials, they are another area of growing influence by the pharmaceutical industry. For example, in a recent survey it was found that about 60% of 192 authors of clinical practice guidelines reported they had financial connections with the companies whose drugs were under consideration. This finding casts serious doubt on the credibility of this important pillar of modern clinical practice. It needs urgent reparative action. One of them is prospective and retrospective disclosure of financial conflict of interest by authors of CPGs.A Conference on Guideline Standardization (COGS was convened in April 2002 'to define a standard for guideline reporting that would promote guideline quality and facilitate implementation'. It includes items for standardization, conceptual issues, up gradation, conflict of interest, patient interest and systematization. Even items for individual preferences, choice or values are not neglected. Special mention must be made of items that specify disclosure of conflict of interest both in the Developer (including the organization that develops and the individuals involved in the guideline's formulation, as well as in the sponsor or funding source (and its role in developing and/or reporting the guideline.Recommendations of CPGs and CDR panels are conflicting. One considers effectiveness, the other cost-effectiveness. However, CPGs do not adhere to established methodological standards; critical information that would attest to validity is regularly absent; explicit criteria to grade scientific evidence that supports their recommendations is absent from 82% of guidelines; 87% are not in a position to report whether a systematic literature search was performed; 67% do not describe the type of professionals used in guidelines development; and there is marked variation in the quality of guidelines. Moreover, CPG guideline layers often are conflicted in their interests. The problem can be resolved to a large extent by taking a simple step: making CPG panelists go into cost effectiveness along with recommending Guidelines. What then happens is they have to consider not only effectiveness but also costs. Effectiveness can be fudged, cost cannot. Why? Because, what is the cost is well known. Therapies in Guidelines should be recommended and graded according to whether they are Most, Moderately or Least Cost Effective. For that CPGs will have to perform an economic analysis as well. This will meet with resistance for obvious reasons. Since guideline groups cannot be kept on the straight and narrow path and till we find fool proof ways of keeping them thus, we have no option but to stress that under no circumstances they can mislead, or get misled themselves, in the name of patient advocacy, to recommend costly new therapies which have still not proved their effectiveness conclusively, nor get away with conflicted recommendations, which it is still not obligatory to reveal. A simple rider like making it mandatory for guideline groups to go into both effectiveness and cost effectiveness takes care that this is ensured.The AGREE Collaboration (AGREE stands for Appraisal of Guidelines, Research and Evaluation has created and validated tools by which clinicians can themselves rate guidelines by identifying factors that determine their quality. To facilitate this process, a body like the GAC (Guidelines Advisory Committee applies the AGREE criteria to individual guidelines and rates and endorses the best possible guideline. Clinical Practice Guidelines are another example of an excellent idea likely to go to seed due to sponsor manipulation and forces of the market place camouflaging as evidence based medicine. The need to weed out conflicted experts and make the process of therapy selection transparent must go hand in hand with laying down clear-cut criteria for guideline formulation and rejection of conflicted submissions by vigilant journal publication policies and editors. A number of disease-specific foundations are heavily funded by industry that creates serious conflict of interest likely to result in favourably recommending therapies of sponsors. The case of Alteplase and the American Heart Foundation is a recent example. Whistle blowing papers and research to expose misdemeanours must be undertaken and journals and their editors should welcome such papers as legitimate research, without encouraging a witch-hunt. The USP of journals and researchers is credibility. Credibility can be marketed, but it can't be bought. Sponsors will be forced to seek such credibility without allowing them to compromise it. Such is the game journal publishers/editors and genuine researchers will have to play with sponsors. But they can do so only if they are thoroughly competent and have abiding faith in an uncompromising set of ethical values. The Task Force of the AAMC, in its two reports of 2001 and 2002, recognises the necessity and inevitability of the academia-industry connect, but wants to avoid its undesirable influence on the integrity of research and the welfare of human research subjects. It is specially concerned that public, activist and governmental control and concern does not cast a spanner in the works of a potentially promising relationship.Constant pampering by sponsors has dulled most drug prescribers' critical capabilities. Sponsorship is a potent anaeasthetic to many ethical concerns. It can blunt the thrust of many a sabre-rattling critic.Both medical associations and research journal editors are getting concerned with individual and institutional conflicts of interest in the conduct of clinical research and documents are now available which address these issues.Edits are concerned with whether academic medicine is for sale (Angell, in N Engl J Med 2000; what are the controlling interests of research (Editorial, CMAJ, 2002a; how the invisible hand of the marketing department works (Editorial, CMAJ , 2002b; how contracts affect institutions and academic freedom (Drazen in N Engl J Med , 2002; what are the choices for the academic medical center in collaborating with industry - (Moses et al in N Engl J Med , 2002; how does one ensure integrity of scientific research (Editorial, Lancet , 2002; how one maintains public trust in clinical research (Kelch in N Engl J Med , 2002; how does one ensure academic freedom in clinical research (Nathan and Weatherall, editorial, in N Engl J Med 2002; how to maintain the integrity of the scientific record (Smith R.: [editorial]. BMJ 2001; and is the university-industrial complex going out of control? ( Nature , 2001. The 2001 ICMJE revision call for full disclosure of the sponsor's role in research, as well as assurance that investigators are independent of sponsors, are fully accountable for the design and conduct of the trial, have independent access to all trial data and control all editorial and publication decisions. ICMJE has taken an important step in ensuring greater accountability in the research process, its publication and preventing possible malevolent impact on gullible readers. However the findings of a 2002 study suggest that academic institutions routinely participate in clinical research that does not adhere to ICMJE standards of accountability, access to data and control of publication. An issue of major concern is protection of the interests of research subjects because patients agree to become research subjects not only for personal medical benefit but, as an extension, to benefit the rest of the patient population and also advance medical research. These interests are hardly served if research data is doctored or concealed, as can happen to protect industry interests or if industry dictates the terms and conditions of research contracts.The progress of biomedical research depends on ready availability of research subjects. But such ready availability depends on ethical practices by researchers and sponsoring agencies. The clear-cut power to protect research subjects' interests should be inbuilt in the contract process. Establishment of Best Practice Guidelines for researchers and academic medical centers and Good Publication Practice for sponsoring pharmaceuticals are two important developments worth a close study and replication to assess feasibility across diverse geographical areas. Another area of concern is pharma's focus on the marketability rather than usefulness of products. There is an inevitable slant to produce not necessarily useful but marketable products which ensure profitability of industry and research grants outflow to academia. A disturbing but very relevant finding in this connection is that drugs which can be called "substantial improvements" over available treatments is only, mark the finding, a measly 6%. Industry supports new therapies, not traditional therapy, irrespective of what is effective. Whatever traditional therapy is supported is also most probably because the industry concerned has a product with a big stake there, which has remained a 'gold standard' or which that player thinks still has some 'juice' left.The larger issue of benefit to society also concerns us here when we realize that industry sponsorship is mainly for potential medications, not for trying to determine whether there may be non-pharmacological interventions that may be equally good, if not better. This is the reason why methods like yoga, psychotherapy, meditation, non-medicated non-mechanised relaxation will not find industry sponsors readily and will never be proved useful apart from anecdotal reporting.In the paradigm shift towards biological psychiatry, the role of industry sponsorship is not overt but probably more pervasive than many have realized or the right thinking may consider good for the health of the branch in the long run. Ask yourself a simple question: Why should industry sponsor psychotherapeutic research? And why should industry not sponsor biological research? Which of the two will give rise to drugs? How will the profits pour in? The answer is simple enough.Essentially, there are four types of drugs. First, drugs that work and have minimal side-effects; second, drugs which work but have serious side-effects; third, drugs that do not work but have minimal side-effects; and fourth, drugs which work minimally but have serious side-effects. Pharma's major propelling force can only be producing the first type. They accept the second type only till they can lay their hands on the first and, in any case, never project or accept them as the first. The third type can be occasionally played around with to shore up profits, but never by projecting them as the first type. The fourth type are the laggards, a real threat to credibility and therefore do not deserve any market hype or promotion. What makes pharma adopt even questionable means to make profits? Reasons are mainly three: one, pharma business cannot depend only on genuine discoveries; second, newer drugs with no effect are also with no, or little, side-effects - and that helps; and third, image building needs to balance profit with shored up credibility. Industry players have to strike the right balance between profit making and credibility. In profit making, the marketing champions play their role. In credibility ratings, researchers and paid spokes-persons play their role. All is hunky dory till marketing is based on credibility. When there is nothing available to make for credibility, something is projected as one and marketing carried out, in the calculated hope that profits can accrue, since that must continue endlessly. That is what makes pharma adopt even questionable means to make profits.The process of self-correction set into motion due to greater clout of conscientious researchers, unrelenting expose by medical journalists and supportive editors, patients right activism and law suits against industry will, hopefully, help tilt the balance towards value-based advance, even if belated, and done grudgingly. Major industry players may soften the offensive of such self-correction only by playing the game according to the rules. The earlier the major players understand this, the better it is for all concerned.

    2008-01-01

    To assess its usefulness, the peak version of color intensity projections (CIPs) was used to display a summary of the grayscale images composing a renogram as a single color image. Method For each pixel in a renogram, the time point with the maximum intensity was used to control the hue of the color of the corresponding pixel in the CIPs image. The hue ranged over red-yellow-green-light blue-blue with red representing the earliest time. Results For subjects with normal appearing kidneys, the injection site shows up in red, the kidneys in a red-yellow and the bladder in a green-blue. A late fill kidney typically appeared greener or bluer than a normal kidney indicating it reached its peak intensity at a later time point than normal. Conclusions Having the time and intensity information summarized in a single image promises to speed up the initial impression of patients by less experienced interpreters and should also provide a valuable training tool.

    Full Text Available The review concerns the monograph “Peregruznoe I Burial Ground: Results of Interdisciplinary Research. The book was prepared by the team of authors including archaeologists, anthropologists, paleosoil specialists, archaeozoologists. The review contains examination of materials and main conclusions for every chapter of the monograph. The monograph is devoted to the analysis of materials from 52 burial mounds dated from the Aeneolith to the Middle Ages. Most of them were erected in the Sarmatian period. In the review, the controversial points concerning the reconstruction of the paleodemographic and physicalgenetic structure of the buried Sarmatian population were pointed out. The authors consider that the gender disharmony of the Early and Middle Sarmatian samples was determined by the peculiarities of mounds formation of nomadic groups localized at the winter and summer nomad camps. This conclusion provokes some objections. As a positive moment, it should be noted that the authors have discovered new trends by means of analysis of cultural and chronological Sarmatian groups according to anthropological data. The monograph presents new interesting data related to reconstruction of the social structure of the Sarmatian societies, burial mound construction, the taxonomic composition of animals from grave pits and mounds. It is necessary to note, that the authors carried out a great deal of investigation and study. The monograph presents abundant scientific data. Interpretation of this material has a great potential which resources are far from being exhausted. The book is going to be a significant event not only for the study of the Volga-Ural steppe antiquities but for all over the Sarmatian archaeology.

    Background A large number of observational studies have reported harmful effects of low 25-hydroxyvitamin D (25OHD) levels on non-skeletal outcomes. We performed a systematic quantitative review on characteristics of randomized clinical trials (RCTs) included in meta-analyses (MAs) on non-skeletal effects of vitamin D supplementation. Methods and findings We identified systematic reviews (SR) reporting summary data in terms of MAs of RCTs on selected non-skeletal outcomes. For each outcome, we summarized the results from available SRs and scrutinized included RCTs for a number of predefined characteristics. We identified 54 SRs including data from 210 RCTs. Most MAs as well as the individual RCTs reported null-findings on risk of cardiovascular diseases, type 2 diabetes, weight-loss, and malignant diseases. Beneficial effects of vitamin D supplementation was reported in 1 of 4 MAs on depression, 2 of 9 MAs on blood pressure, 3 of 7 MAs on respiratory tract infections, and 8 of 12 MAs on mortality. Most RCTs have primarily been performed to determine skeletal outcomes, whereas non-skeletal effects have been assessed as secondary outcomes. Only one-third of the RCTs had low level of 25OHD as a criterion for inclusion and a mean baseline 25OHD level below 50 nmol/L was only present in less than half of the analyses. Conclusions Published RCTs have mostly been performed in populations without low 25OHD levels. The fact that most MAs on results from RCTs did not show a beneficial effect does not disprove the hypothesis suggested by observational findings on adverse health outcomes of low 25OHD levels.

    An HPLC method with UV detection and separation with the use of a C30 reversed phase analytical column for the determination of chemical purity and assay of menaquinone-7 (MK7) in one chromatographic run was developed. The method is superior to the methods published in the USP Monograph in terms of selectivity, sensitivity and accuracy, as well as time, solvent and sample consumption. The developed methodology was applied to MK7 samples of active pharmaceutical ingredient (API) purity, MK7 samples of lower quality and crude MK7 samples before purification. The comparison of the results revealed that the use of USP methodology could lead to serious overestimation (up to a few percent) of both purity and MK7 assay in menaquinone-7 samples.

    A virtually unknown brief commentary by Freud on the characteristics of his own dreams is described and discussed. Freud's mini-monograph, discovered after some 80 years, has autobiographical, theoretical and organisational significance in the enigmatic context of the early development of psychoanalysis. Found among papers of Alfred Adler, this extraordinary document adds to our knowledge of psychoanalytic history, including the significance of dreams in the evolution of psychoanalytic thought. Freud's commentary permitted the identification of a particular dream as his own. This dream had been presented in anonymity to the fledgling Vienna Psychoanalytic Society for interpretation. The dream was later inserted, again anonymously, into The Interpretation of Dreams with Freud's own remarkable pre-oedipal interpretation. Freud's conflicted relationships with Adler and Jung are considered in historical context.

    General Internal Medicine (GIM) faces a burgeoning crisis in the United States, while patients with chronic illness confront a disintegrating health care system. Reimbursement that rewards using procedures and devices rather than thoughtful examination and management, plus onerous administrative burdens, are prompting physicians to pursue specialties other than GIM. This monograph promotes 9 principles supporting the concept of Coordinated Care--a strategy to sustain quality and enhance the attractiveness and viability of care delivered by highly trained General Internists who specialize in the longitudinal care of adult patients with acute and chronic illness. This approach supplements and extends the concept of the Advanced Medical Home set forth by the American College of Physicians. Specific components of Coordinated Care include clinical support, information management, and access and scheduling. Success of the model will require changes in the payment system that fairly reimburse physicians who provide leadership to teams that deliver high quality, coordinated care.
