    2008-12-01

    Full Text Available Abstract Background Since the full genome sequences of Saccharomyces cerevisiae were released in 1996, genome sequences of over 90 fungal species have become publicly available. The heterogeneous formats of genome sequences archived in different sequencing centers hampered the integration of the data for efficient and comprehensive comparative analyses. The Comparative Fungal Genomics Platform (CFGP was developed to archive these data via a single standardized format that can support multifaceted and integrated analyses of the data. To facilitate efficient data visualization and utilization within and across species based on the architecture of CFGP and associated databases, a new genome browser was needed. Results The Seoul National University Genome Browser (SNUGB integrates various types of genomic information derived from 98 fungal/oomycete (137 datasets and 34 plant and animal (38 datasets species, graphically presents germane features and properties of each genome, and supports comparison between genomes. The SNUGB provides three different forms of the data presentation interface, including diagram, table, and text, and six different display options to support visualization and utilization of the stored information. Information for individual species can be quickly accessed via a new tool named the taxonomy browser. In addition, SNUGB offers four useful data annotation/analysis functions, including 'BLAST annotation.' The modular design of SNUGB makes its adoption to support other comparative genomic platforms easy and facilitates continuous expansion. Conclusion The SNUGB serves as a powerful platform supporting comparative and functional genomics within the fungal kingdom and also across other kingdoms. All data and functions are available at the web site http://genomebrowser.snu.ac.kr/.

    Full Text Available Recently, web browser based applications have become very popular in many domains. As an important method to ensure the quality of Web applications, Web testing attracts more and more attentions in the academic community and industrial world. Testing Web applications raises new problems and faces very high challenges. Recently web applications have grown rapidly and have become more and more complex. As web applications become more complex, there is a growing concern about their quality. Web application testing is a challenging work owing to its dynamic behaviors and complex dependencies. As in case what if the end user uses different types of browsers to access the application. So, to deal with Browser compatibility issue this work proposes Browser based testing tools named as Watir (Web Application Testing in Ruby and WET for the scenario of web-based applications. Starting with the preliminary architectural design, this paper includes the testing scenario for both the tools alongwith the comparative analysis based on well defined parameters.

    Full Text Available In this current era of information technology websites are very important means of communication. Lot of efforts is required by different institutions / organizations to portray complete information on beautifully designed websites. Websites act as an online agent through which a user can get his work done without physically visiting the organizations. Website design is given with a very critical look by the designer so that it can provide users with all the facilities of the concerned institutions / organizations online. To make websites behavior similar in all the different browsers employed by the different categories of the users, the responsibility of the designer and the concerned institutions / organizations increases manifold. In this research paper author developed an online tool using .NET Framework using C# to study cross browser compatibility as Design issue in various categories of the websites like Job portals, Government, educational, Commercial and Social networking. The automated tool developed by author function on the basis of the different standards prescribed in W3C guidelines document UAAG 2.0 [7] and act like a parser and renders the complete code of the website and produces result on basis of the behavior of the websites in five most popular and widely used Browsers like parameters like Internet Explorer[7,8,9], Chrome, Safari, Fire fox. Each Browser is tested on the basis of the five parameters which are included in the parser are Blinking, Active X control, Website Resolution; image Formats, HTML Tag errors. The results obtained after testing five different categories of websites shows that educational and social networking sites shows least compatibility in multiple browsers where as job portals, commercial and government websites shows 100% compliance to the website design standards recommended by W3C w.r.t browser compatibility of different websites on different browsing platform.

  8. CpGislandEVO: A Database and Genome Browser for Comparative Evolutionary Genomics of CpG Islands

    Directory of Open Access Journals (Sweden)

    Guillermo Barturen

    2013-01-01

    Full Text Available Hypomethylated, CpG-rich DNA segments (CpG islands, CGIs are epigenome markers involved in key biological processes. Aberrant methylation is implicated in the appearance of several disorders as cancer, immunodeficiency, or centromere instability. Furthermore, methylation differences at promoter regions between human and chimpanzee strongly associate with genes involved in neurological/psychological disorders and cancers. Therefore, the evolutionary comparative analyses of CGIs can provide insights on the functional role of these epigenome markers in both health and disease. Given the lack of specific tools, we developed CpGislandEVO. Briefly, we first compile a database of statistically significant CGIs for the best assembled mammalian genome sequences available to date. Second, by means of a coupled browser front-end, we focus on the CGIs overlapping orthologous genes extracted from OrthoDB, thus ensuring the comparison between CGIs located on truly homologous genome segments. This allows comparing the main compositional features between homologous CGIs. Finally, to facilitate nucleotide comparisons, we lifted genome coordinates between assemblies from different species, which enables the analysis of sequence divergence by direct count of nucleotide substitutions and indels occurring between homologous CGIs. The resulting CpGislandEVO database, linking together CGIs and single-cytosine DNA methylation data from several mammalian species, is freely available at our website.

    A special browser is a specialized browser designed only for a specific website, providing a very comfortable user interface for that website. However, it is usually necessary to update the special browser when there is a design change to the website. Therefore, a special browser should be easy to update. I propose such a browser here. The proposed browser also has robustness, meaning that it does not need to be updatedfor a small change to the website. abstract environment.

    2012-07-01

    Full Text Available Web browser is one of the most important internet facilities for surfing the internet. A good web browser must incorporate literally tens of features such as integrated search engine, automatic updates, etc. Each year, ten web browsers are formally introduced as top best reviewers by some organizations. In this paper, we propose the implementation of TOPSIS technique to rank ten web browsers. The proposed model of this paper uses five criteria including speed, features, security, technical support and supported configurations. In terms of speed, Safari is the best web reviewer followed by Google Chrome and Internet Explorer while Opera is the best web reviewer when we look into 20 different features. We have also ranked these web browsers using all five categories together and the results indicate that Opera, Internet explorer, Firefox and Google Chrome are the best web browsers to be chosen.

    For the past 15 years, the UCSC Genome Browser (http://genome.ucsc.edu/) has served the international research community by offering an integrated platform for viewing and analyzing information from a large database of genome assemblies and their associated annotations. The UCSC Genome Browser has been under continuous development since its inception with new data sets and software features added frequently. Some release highlights of this year include new and updated genome browsers for various assemblies, including bonobo and zebrafish; new gene annotation sets; improvements to track and assembly hub support; and a new interactive tool, the "Data Integrator", for intersecting data from multiple tracks. We have greatly expanded the data sets available on the most recent human assembly, hg38/GRCh38, to include updated gene prediction sets from GENCODE, more phenotype- and disease-associated variants from ClinVar and ClinGen, more genomic regulatory data, and a new multiple genome alignment.

    2009-09-01

    We describe an open source, portable, JavaScript-based genome browser, JBrowse, that can be used to navigate genome annotations over the web. JBrowse helps preserve the user's sense of location by avoiding discontinuous transitions, instead offering smoothly animated panning, zooming, navigation, and track selection. Unlike most existing genome browsers, where the genome is rendered into images on the webserver and the role of the client is restricted to displaying those images, JBrowse distributes work between the server and client and therefore uses significantly less server overhead than previous genome browsers. We report benchmark results empirically comparing server- and client-side rendering strategies, review the architecture and design considerations of JBrowse, and describe a simple wiki plug-in that allows users to upload and share annotation tracks.

    2011-01-01

    ELSSI is a web-based event metadata (TAG) browser and event-level selection service for ATLAS. TAGs from all ATLAS physics and Monte Carlo data sets are routinely loaded into Oracle databases as an integral part of event processing. As data volumes increase, more and more sites are joining the distributed TAG data hosting topology. Meanwhile, TAG content and database schemata continue to evolve as new user requirements and additional sources of metadata emerge. All of this has posed many challenges to the development of ELSSI, which must support vast amounts of TAG data while source, content, geographic locations, and user query patterns may change over time. In this paper, we describe some of the challenges encountered in the process of developing ELSSI, and the software engineering strategies adopted to address those challenges. Approaches to management of access to data, browsing, data rendering, query building, query validation, execution, connection management, and communication with auxiliary services a...

    2015-05-01

    Full Text Available Browsers are applications that allow Internet access. A defining characteristic is their unidirectionality: Navigator-> Internet. The purpose of this article is to support the idea of Intelligent Browsers that is defined by bidirectional: Navigator-> Internet and Internet-> Navigator. The fundamental idea is that the Internet contains huge resources of knowledge, but they are “passive”. The purpose of this article is to propose the “activation” of this knowledge so that they, through “Intelligent Browsers”, to become from Sitting Ducks to Active Mentors. Following this idea, the present article proposes changes to Bookmarks function, from the current status of Favorites to Recommendations. The article presents an analysis of the utility of this function (by presenting a research of web browsing behaviors and in particular finds that the significance of this utility has decreased lately (to the point of becoming almost useless, as will be shown, in terms data-information-knowledge. Finally, it presents the idea of a project which aims to be an applied approach that anticipates the findings of this study and the concept of Intelligent Browsers (or Active Browsers required in the context of the Big Data concept.

  1. Trajectory Browser Website

    2012-01-01

    The Trajectory Browser is a web-based tool developed at the NASA Ames Research Center to be used for the preliminary assessment of trajectories to small-bodies and planets and for providing relevant launch date, time-of-flight and V requirements. The site hosts a database of transfer trajectories from Earth to asteroids and planets for various types of missions such as rendezvous, sample return or flybys. A search engine allows the user to find trajectories meeting desired constraints on the launch window, mission duration and delta V capability, while a trajectory viewer tool allows the visualization of the heliocentric trajectory and the detailed mission itinerary. The anticipated user base of this tool consists primarily of scientists and engineers designing interplanetary missions in the context of pre-phase A studies, particularly for performing accessibility surveys to large populations of small-bodies. The educational potential of the website is also recognized for academia and the public with regards to trajectory design, a field that has generally been poorly understood by the public. The website is currently hosted on NASA-internal URL http://trajbrowser.arc.nasa.gov/ with plans for a public release as soon as development is complete.

    2011-01-01

    Demand for more advanced Web applications is the driving force behind Web browser evolution. Recent requirements for Rich Internet Applications, such as mashing-up data and background processing, are emphasizing the need for building and executing Web applications as a coordination of browser execution contexts. Since development of such Web applications depends on cross-context communication, many browser primitives and client-side frameworks have been developed to support this communication. In this paper we present a systematization of cross-context communication systems for Web browsers. Based on an analysis of previous research, requirements for modern Web applications and existing systems, we extract a framework for classifying cross-context communica-tion systems. Using the framework, we evaluate the current ecosystem of cross-context communication and outline directions for future Web research and engineering.

  5. CompaGB: An open framework for genome browsers comparison

    2011-05-01

    Full Text Available Abstract Background Tools to visualize and explore genomes hold a central place in genomics and the diversity of genome browsers has increased dramatically over the last few years. It often turns out to be a daunting task to compare and choose a well-adapted genome browser, as multidisciplinary knowledge is required to carry out this task and the number of tools, functionalities and features are overwhelming. Findings To assist in this task, we propose a community-based framework based on two cornerstones: (i the implementation of industry promoted software qualification method (QSOS adapted for genome browser evaluations, and (ii a web resource providing numerous facilities either for visualizing comparisons or performing new evaluations. We formulated 60 criteria specifically for genome browsers, and incorporated another 65 directly from QSOS's generic section. Those criteria aim to answer versatile needs, ranging from a biologist whose interest primarily lies into user-friendly and informative functionalities, a bioinformatician who wants to integrate the genome browser into a wider framework, or a computer scientist who might choose a software according to more technical features. We developed a dedicated web application to enrich the existing QSOS functionalities (weighting of criteria, user profile with features of interest to a community-based framework: easy management of evolving data, user comments... Conclusions The framework is available at http://genome.jouy.inra.fr/CompaGB. It is open to anyone who wishes to participate in the evaluations. It helps the scientific community to (1 choose a genome browser that would better fit their particular project, (2 visualize features comparatively with easily accessible formats, such as tables or radar plots and (3 perform their own evaluation against the defined criteria. To illustrate the CompaGB functionalities, we have evaluated seven genome browsers according to the implemented methodology

    Full Text Available The technology evolution of smartphones, systems and the growing of telecommunications, allow the use of Augmented Reality in the exploration of geo-referenced information, complementing the real environment of the users with various types of content displayed on robust mobile cameras through applications called augmented reality browsers. Although this type of application is being in development and growing use by society, the technology, and especially its software architecture do not have any kind of standardization. This work presents concepts about augmented reality browsers for mobile devices. It shows the main aspects and applications of those types of reality. Besides that, the specific features of those types of architecture are discussed and compared, and new architecture, whose most relevant feature is the interoperability of applications in various platforms for mobile devices, are presented. This work has the objective to develop an architectural framework for the development of these browsers.

    2009-04-01

    Browser games--mostly persistent game worlds that can be used without client software and monetary cost with a Web browser--belong to the understudied digital game types, although they attract large player communities and motivate sustained play. The present work reports findings from an online survey of 8,203 players of a German strategy browser game ("Travian"). Results suggest that multiplayer browser games are enjoyed primarily because of the social relationships involved in game play and the specific time and flexibility characteristics ("easy-in, easy-out"). Competition, in contrast, seems to be less important for browser gamers than for users of other game types. Findings are discussed in terms of video game enjoyment and game addiction. PMID:19260776

    Ueno; Asai; Arita

    1999-01-01

    We have constructed a general framework for integrating application programs with control through a local Web browser. This method is based on a simple inter-process message function from an external process to application programs. Commands to a target program are prepared in a script file, which is parsed by a message dispatcher program. When it is used as a helper application to a Web browser, these messages will be sent from the browser by clicking a hyper-link in a Web document. Our framework also supports pluggable extension-modules for application programs by means of dynamic linking. A prototype system is implemented on our molecular structure-viewer program, MOSBY. It successfully featured a function to load an extension-module required for the docking study of molecular fragments from a Web page. Our simple framework facilitates the concise configuration of Web softwares without complicated knowledge on network computation and security issues. It is also applicable for a wide range of network computations processing private data using a Web browser. PMID:11072353

    International Nuclear Information System (INIS)

    Geant4 is a toolkit for the simulation of the passage of particles through matter. The Geant4 visualization system supports many drivers including OpenGL[1], OpenInventor, HepRep[2], DAWN[3], VRML, RayTracer, gMocren[4] and ASCIITree, with diverse and complementary functionalities. Web applications have an increasing role in our work, and thanks to emerging frameworks such as Wt [5], building a web application on top of a C++ application without rewriting all the code can be done. Because the Geant4 toolkit's visualization and user interface modules are well decoupled from the rest of Geant4, it is straightforward to adapt these modules to render in a web application instead of a computer's native window manager. The API of the Wt framework closely matches that of Qt [6], our experience in building Qt driver will benefit for Wt driver. Porting a Geant4 application to a web application is easy, and with minimal effort, Geant4 users can replicate this process to share their own Geant4 applications in a web browser.

  17. Controlling EPICS from a web browser

    International Nuclear Information System (INIS)

    An alternative to using a large graphical display manager like MEDM [1,2] to interface to a control system, is to use individual control objects, such as text boxes, meters, etc., running in a browser. This paper presents three implementations of this concept, one using ActiveX controls, one with Java applets, and another with Microsoft Agent. The ActiveX controls have performance nearing that of MEDM, but they only work on Windows platforms. The Java applets require a server to get around Web security restrictions and are not as fast, but they have the advantage of working on most platforms and with both of the leading Web browsers. The agent works on Windows platforms with and without a browser and allows voice recognition and speech synthesis, making it somewhat more innovative than MEDM

  20. gEVAL — a web-based browser for evaluating genome assemblies

    Science.gov (United States)

    Chow, William; Brugger, Kim; Caccamo, Mario; Sealy, Ian; Torrance, James; Howe, Kerstin

    2016-01-01

    Motivation: For most research approaches, genome analyses are dependent on the existence of a high quality genome reference assembly. However, the local accuracy of an assembly remains difficult to assess and improve. The gEVAL browser allows the user to interrogate an assembly in any region of the genome by comparing it to different datasets and evaluating the concordance. These analyses include: a wide variety of sequence alignments, comparative analyses of multiple genome assemblies, and consistency with optical and other physical maps. gEVAL highlights allelic variations, regions of low complexity, abnormal coverage, and potential sequence and assembly errors, and offers strategies for improvement. Although gEVAL focuses primarily on sequence integrity, it can also display arbitrary annotation including from Ensembl or TrackHub sources. We provide gEVAL web sites for many human, mouse, zebrafish and chicken assemblies to support the Genome Reference Consortium, and gEVAL is also downloadable to enable its use for any organism and assembly. Availability and Implementation: Web Browser: http://geval.sanger.ac.uk, Plugin: http://wchow.github.io/wtsi-geval-plugin.

    2012-01-01

    Full Text Available Abstract Background With the rapid growth of genome sequencing projects, genome browser is becoming indispensable, not only as a visualization system but also as an interactive platform to support open data access and collaborative work. Thus a customizable genome browser framework with rich functions and flexible configuration is needed to facilitate various genome research projects. Results Based on next-generation web technologies, we have developed a general-purpose genome browser framework ABrowse which provides interactive browsing experience, open data access and collaborative work support. By supporting Google-map-like smooth navigation, ABrowse offers end users highly interactive browsing experience. To facilitate further data analysis, multiple data access approaches are supported for external platforms to retrieve data from ABrowse. To promote collaborative work, an online user-space is provided for end users to create, store and share comments, annotations and landmarks. For data providers, ABrowse is highly customizable and configurable. The framework provides a set of utilities to import annotation data conveniently. To build ABrowse on existing annotation databases, data providers could specify SQL statements according to database schema. And customized pages for detailed information display of annotation entries could be easily plugged in. For developers, new drawing strategies could be integrated into ABrowse for new types of annotation data. In addition, standard web service is provided for data retrieval remotely, providing underlying machine-oriented programming interface for open data access. Conclusions ABrowse framework is valuable for end users, data providers and developers by providing rich user functions and flexible customization approaches. The source code is published under GNU Lesser General Public License v3.0 and is accessible at http://www.abrowse.org/. To demonstrate all the features of ABrowse, a live demo for

    Genome browsers have gained importance as more genomes and related genomic information become available. However, the increase of information brought about by new generation sequencing technologies is, at the same time, causing a subtle but continuous decrease in the efficiency of conventional genome browsers. Here, we present Genome Maps, a genome browser that implements an innovative model of data transfer and management. The program uses highly efficient technologies from the new HTML5 standard, such as scalable vector graphics, that optimize workloads at both server and client sides and ensure future scalability. Thus, data management and representation are entirely carried out by the browser, without the need of any Java Applet, Flash or other plug-in technology installation. Relevant biological data on genes, transcripts, exons, regulatory features, single-nucleotide polymorphisms, karyotype and so forth, are imported from web services and are available as tracks. In addition, several DAS servers are already included in Genome Maps. As a novelty, this web-based genome browser allows the local upload of huge genomic data files (e.g. VCF or BAM) that can be dynamically visualized in real time at the client side, thus facilitating the management of medical data affected by privacy restrictions. Finally, Genome Maps can easily be integrated in any web application by including only a few lines of code. Genome Maps is an open source collaborative initiative available in the GitHub repository (https://github.com/compbio-bigdata-viz/genome-maps). Genome Maps is available at: http://www.genomemaps.org.

    As vertebrate genome sequences near completion and research refocuses to their analysis, the issue of effective genome annotation display becomes critical. A mature web tool for rapid and reliable display of any requested portion of the genome at any scale, together with several dozen aligned annotation tracks, is provided at http://genome.ucsc.edu. This browser displays assembly contigs and gaps, mRNA and expressed sequence tag alignments, multiple gene predictions, cross-species homologies, single nucleotide polymorphisms, sequence-tagged sites, radiation hybrid data, transposon repeats, and more as a stack of coregistered tracks. Text and sequence-based searches provide quick and precise access to any region of specific interest. Secondary links from individual features lead to sequence details and supplementary off-site databases. One-half of the annotation tracks are computed at the University of California, Santa Cruz from publicly available sequence data; collaborators worldwide provide the rest. Users can stably add their own custom tracks to the browser for educational or research purposes. The conceptual and technical framework of the browser, its underlying MYSQL database, and overall use are described. The web site currently serves over 50,000 pages per day to over 3000 different users. PMID:12045153

    I will introduce and describe Aladin Lite1, a lightweight interactive sky viewer running natively in the browser. The past five years have seen the emergence of powerful and complex web applications, thanks to major improvements in JavaScript engines and the advent of HTML5. At the same time, browser plugins Java applets, Flash, Silverlight) that were commonly used to run rich Internet applications are declining and are not well suited for mobile devices. The Aladin team took this opportunity to develop Aladin Lite, a lightweight version of Aladin geared towards simple visualization of a sky region. Relying on the widely supported HTML5 canvas element, it provides an intuitive user interface running on desktops and tablets. This first version allows one to interactively visualize multi-resolution HEALPix image and superimpose tabular data and footprints. Aladin Lite is easily embeddable on any web page and may be of interest for data providers which will be able to use it as an interactive previewer for their own image surveys, previously pre-processed as explained in details in the poster "Create & publish your Hierarchical Progressive Survey". I will present the main features of Aladin Lite as well as the JavaScript API which gives the building blocks to create rich interactions between a web page and Aladin Lite.

    The increasing number of vertebrate genomes being sequenced in draft or finished form provide a unique opportunity to study and decode the language of DNA sequence through comparative genome alignments. However, novel tools and strategies are required to accommodate this increasing volume of genomic information and to facilitate experimental annotation of genome function. Here we present the ECR Browser, a tool that provides an easy and dynamic access to whole genome alignments of human, mouse, rat and fish sequences. This web-based tool (http://ecrbrowser.dcode.org) provides the starting point for discovery of novel genes, identification of distant gene regulatory elements and prediction of transcription factor binding sites. The genome alignment portal of the ECR Browser also permits fast and automated alignment of any user-submitted sequence to the genome of choice. The interconnection of the ECR browser with other DNA sequence analysis tools creates a unique portal for studying and exploring vertebrate genomes.

    2016-01-01

    The paper presents an open source system that allows the user to interact with a 3D molecular viewer using associated hand gestures for rotating, scaling and panning the rendered model. The novelty of this approach is that the entire application is browser-based and doesn't require installation of third party plug-ins or additional software components in order to visualize the supported chemical file formats. This kind of solution is suitable for instruction of users in less IT oriented environments, like medicine or chemistry. For rendering various molecular geometries our team used GLmol (a molecular viewer written in JavaScript). The interaction with the 3D models is made with Leap Motion controller that allows real-time tracking of the user's hand gestures. The first results confirmed that the resulting application leads to a better way of understanding various types of translational bioinformatics related problems in both biomedical research and education.

  16. Interactive metagenomic visualization in a Web browser

    Directory of Open Access Journals (Sweden)

    Phillippy Adam M

    2011-09-01

    Full Text Available Abstract Background A critical output of metagenomic studies is the estimation of abundances of taxonomical or functional groups. The inherent uncertainty in assignments to these groups makes it important to consider both their hierarchical contexts and their prediction confidence. The current tools for visualizing metagenomic data, however, omit or distort quantitative hierarchical relationships and lack the facility for displaying secondary variables. Results Here we present Krona, a new visualization tool that allows intuitive exploration of relative abundances and confidences within the complex hierarchies of metagenomic classifications. Krona combines a variant of radial, space-filling displays with parametric coloring and interactive polar-coordinate zooming. The HTML5 and JavaScript implementation enables fully interactive charts that can be explored with any modern Web browser, without the need for installed software or plug-ins. This Web-based architecture also allows each chart to be an independent document, making them easy to share via e-mail or post to a standard Web server. To illustrate Krona's utility, we describe its application to various metagenomic data sets and its compatibility with popular metagenomic analysis tools. Conclusions Krona is both a powerful metagenomic visualization tool and a demonstration of the potential of HTML5 for highly accessible bioinformatic visualizations. Its rich and interactive displays facilitate more informed interpretations of metagenomic analyses, while its implementation as a browser-based application makes it extremely portable and easily adopted into existing analysis packages. Both the Krona rendering code and conversion tools are freely available under a BSD open-source license, and available from: http://krona.sourceforge.net.

    2014-01-01

    Recent years have seen massive, distributed datasets become the norm in neuroimaging research, and the methodologies used to analyze them have, in response, become more collaborative and exploratory. Tools and infrastructure are continuously being developed and deployed to facilitate research in this context: grid computation platforms to process the data, distributed data stores to house and share them, high-speed networks to move them around and collaborative, often web-based, platforms to provide access to and sometimes manage the entire system. BrainBrowser is a lightweight, high-performance JavaScript visualization library built to provide easy-to-use, powerful, on-demand visualization of remote datasets in this new research environment. BrainBrowser leverages modern web technologies, such as WebGL, HTML5 and Web Workers, to visualize 3D surface and volumetric neuroimaging data in any modern web browser without requiring any browser plugins. It is thus trivial to integrate BrainBrowser into any web-based platform. BrainBrowser is simple enough to produce a basic web-based visualization in a few lines of code, while at the same time being robust enough to create full-featured visualization applications. BrainBrowser can dynamically load the data required for a given visualization, so no network bandwidth needs to be waisted on data that will not be used. BrainBrowser's integration into the standardized web platform also allows users to consider using 3D data visualization in novel ways, such as for data distribution, data sharing and dynamic online publications. BrainBrowser is already being used in two major online platforms, CBRAIN and LORIS, and has been used to make the 1TB MACACC dataset openly accessible. PMID:25628562

    This work presents a pWeb - a new language and compiler for parallelization of client-side compute intensive web applications such as surgical simulations. The recently introduced HTML5 standard has enabled creating unprecedented applications on the web. Low performance of the web browser, however, remains the bottleneck of computationally intensive applications including visualization of complex scenes, real time physical simulations and image processing compared to native ones. The new proposed language is built upon web workers for multithreaded programming in HTML5. The language provides fundamental functionalities of parallel programming languages as well as the fork/join parallel model which is not supported by web workers. The language compiler automatically generates an equivalent parallel script that complies with the HTML5 standard. A case study on realistic rendering for surgical simulations demonstrates enhanced performance with a compact set of instructions. PMID:24732497

    2013-01-01

    High-throughput mass spectrometry and antibody-based experiments have begun to produce a large amount of proteomic data sets. Chromosome-based visualization of these data sets and their annotations can help effectively integrate, organize, and analyze them. Therefore, we developed a web-based, user-friendly Chromosome-Assembled human Proteome browsER (CAPER). To display proteomic data sets and related annotations comprehensively, CAPER employs two distinct visualization strategies: track-view for the sequence/site information and the correspondence between proteome, transcriptome, genome, and chromosome and heatmap-view for the qualitative and quantitative functional annotations. CAPER supports data browsing at multiple scales through Google Map-like smooth navigation, zooming, and positioning with chromosomes as the reference coordinate. Both track-view and heatmap-view can mutually switch, providing a high-quality user interface. Taken together, CAPER will greatly facilitate the complete annotation and functional interpretation of the human genome by proteomic approaches, thereby making a significant contribution to the Chromosome-Centric Human Proteome Project and even the human physiology/pathology research. CAPER can be accessed at http://www.bprc.ac.cn/CAPE . PMID:23256906

    With the solution of key scientific and technical problems and development of instrumentation, the application of terahertz technology in various fields has been paid more and more attention. Owing to the unique characteristic advantages, terahertz technology has been showing a broad future in the fields of fast, non-damaging detections, as well as many other fields. Terahertz technology combined with other complementary methods can be used to cope with many difficult practical problems which could not be solved before. One of the critical points for further development of practical terahertz detection methods depends on a good and reliable terahertz spectral database. We developed a BS (browser/server) -based terahertz spectral database recently. We designed the main structure and main functions to fulfill practical requirements. The terahertz spectral database now includes more than 240 items, and the spectral information was collected based on three sources: (1) collection and citation from some other abroad terahertz spectral databases; (2) collected from published literatures; and (3) spectral data measured in our laboratory. The present paper introduced the basic structure and fundament functions of the terahertz spectral database developed in our laboratory. One of the key functions of this THz database is calculation of optical parameters. Some optical parameters including absorption coefficient, refractive index, etc. can be calculated based on the input THz time domain spectra. The other main functions and searching methods of the browser/server-based terahertz spectral database have been discussed. The database search system can provide users convenient functions including user registration, inquiry, displaying spectral figures and molecular structures, spectral matching, etc. The THz database system provides an on-line searching function for registered users. Registered users can compare the input THz spectrum with the spectra of database, according to

    Full Text Available In the phishing attack, the user sends their confidential information on mimic websites and face the financial problem, so the user should be informed immediately about the visiting website. According to the Third Quarter Phishing Activity Trends Report, there are 55,282 new phishing websites have been detected in the month of July 2014. To solve the phishing problem, a browser based add-on system may be one of the best solution to aware the user about the website type. In this paper, a novel browser based add-on system is proposed and compared its performance with the existing antiphishing tools. The proposed anti-phishing tool ‘ePhish’ is compared with the existing browser based antiphishing toolbars. All the anti-phishing tools have been installed in computer systems at an autonomous college to check their performance. The obtained result shows that if the task is divided into a group of systems, it can give better results. For different phishing features, the add-on system tool show around 97 percentage successful results at different case conditions. The current study would be very helpful to countermeasure the phishing attach and the proposed system is able to protect the user by phishing attacks. Since the system tool is capable of handling and managing the phishing website details, so it would be helpful to identify the category of the websites.

    Electronic data resources can enable molecular biologists to query and display many useful features that make benchwork more efficient and drive new discoveries. The UCSC Genome Browser provides a wealth of data and tools that advance one’s understanding of genomic context for many species, enable detailed understanding of data, and provide the ability to interrogate regions of interest. Researchers can also supplement the standard display with their own data to query and share with others. Effective use of these resources has become crucial to biological research today, and this unit describes some practical applications of the UCSC Genome Browser. PMID:19816931

  9. Autoplot: a Browser for Science Data on the Web

    Faden, J.; Weigel, R. S.; West, E. E.; Merka, J.

    2008-12-01

    Autoplot (www.autoplot.org) is software for plotting data from many different sources and in many different file formats. Data from CDF, CEF, Fits, NetCDF, and OpenDAP can be plotted, along with many other sources such as ASCII tables and Excel spreadsheets. This is done by adapting these various data formats and APIs into a common data model that borrows from the netCDF and CDF data models. Autoplot uses a web browser metaphor to simplify use. The user specifies a parameter URL, for example a CDF file accessible via http with a parameter name appended, and the file resource is downloaded and the parameter is rendered in a scientifically meaningful way. When data span multiple files, the user can use a file name template in the URL to aggregate (combine) a set of remote files. So the problem of aggregating data across file boundaries is handled on the client side, allowing simple web servers to be used. The das2 graphics library provides rich controls for exploring the data. Scripting is supported through Python, providing not just programmatic control, but for calculating new parameters in a language that will look familiar to IDL and Matlab users. Autoplot is Java-based software, and will run on most computers without a burdensome installation process. It can also used as an applet or as a servlet that serves static images. Autoplot was developed as part of the Virtual Radiation Belt Observatory (ViRBO) project, and is also being used for the Virtual Magnetospheric Observatory (VMO). It is expected that this flexible, general-purpose plotting tool will be useful for allowing a data provider to add instant visualization capabilities to a directory of files or for general use in the Virtual Observatory environment.

  10. A KML-BASED APPROACH FOR DISTRIBUTED COLLABORATIVE INTERPRETATION OF REMOTE SENSING IMAGES IN THE GEO-BROWSER

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Existing implementations of collaborative image interpretation have many limitations for very large satellite imageries, such as inefficient browsing, slow transmission, etc. This article presents a KML-based approach to support distributed, real-time, synchronous collaborative interpretation for remote sensing images in the geo-browser. As an OGC standard, KML (Keyhole Markup Language has the advantage of organizing various types of geospatial data (including image, annotation, geometry, etc. in the geo-browser. Existing KML elements can be used to describe simple interpretation results indicated by vector symbols. To enlarge its application, this article expands KML elements to describe some complex image processing operations, including band combination, grey transformation, geometric correction, etc. Improved KML is employed to describe and share interpretation operations and results among interpreters. Further, this article develops some collaboration related services that are collaboration launch service, perceiving service and communication service. The launch service creates a collaborative interpretation task and provides a unified interface for all participants. The perceiving service supports interpreters to share collaboration awareness. Communication service provides interpreters with written words communication. Finally, the GeoGlobe geo-browser (an extensible and flexible geospatial platform developed in LIESMARS is selected to perform experiments of collaborative image interpretation. The geo-browser, which manage and visualize massive geospatial information, can provide distributed users with quick browsing and transmission. Meanwhile in the geo-browser, GIS data (for example DEM, DTM, thematic map and etc. can be integrated to assist in improving accuracy of interpretation. Results show that the proposed method is available to support distributed collaborative interpretation of remote sensing image

    Full Text Available We are living in the electronic age where electronic transactions such as e-mail, e-banking, e-commerce and e-learning becoming more and more prominent. To access online for this services, the web browser is today’s almost unique software used. These days’ hackers know that browsers are installed into all computers and can be used to compromise a machine by distributing malware via malicious or hacked websites. Also these sites use JavaScript to manipulate browsers and can drive user system to failures. Each browser have inbuilt features setting that define his behavior, unfortunately most of end users are unwilling to enable or disable this features securely, because many of them still do not understand even basic security concepts nor variety of security technologies present in a browser. This study will deeply discuss specific modern browser inbuilt features settings and associated security risks and we present a framework developed to enhance user surfing safety by configuring automatically all installed browsers features settings securely, we call it Automatic Safe Browser Launcher, to solidify the claim, we check each browser before and after with free tool (browser_tests-1.03 which is a collection of test cases to test browser vulnerability. The more configured security features your browser has, the better protected you are from online threats.

    Science.gov (United States)

    Awale, Mahendra; Reymond, Jean-Louis

    2014-01-01

    To confirm the activity of an initial small molecule ‘hit compound’ from an activity screening, one needs to probe the structure–activity relationships by testing close analogs. The multi-fingerprint browser presented here (http://dcb-reymond23.unibe.ch:8080/MCSS/) enables one to rapidly identify such close analogs among commercially available compounds in the ZINC database (>13 million molecules). The browser retrieves nearest neighbors of any query molecule in multi-dimensional chemical spaces defined by four different fingerprints, each of which represents relevant structural and pharmacophoric features in a different way: sFP (substructure fingerprint), ECFP4 (extended connectivity fingerprint), MQNs (molecular quantum numbers) and SMIfp (SMILES fingerprint). Distances are calculated using the city-block distance, a similarity measure that performs as well as Tanimoto similarity but is much faster to compute. The list of up to 1000 nearest neighbors of any query molecule is retrieved by the browser and can be then clustered using the K-means clustering algorithm to produce a focused list of analogs with likely similar bioactivity to be considered for experimental evaluation.

    M K Naskar; D Kundu; M Chatterjee

    2009-10-01

    Silicalite-1 zeolite membranes were prepared hydrothermally on the porous ceramic supports, both unmodified and modified with 3-aminopropyl triethoxysilane (APTES) as a coupling agent following ex situ (secondary) crystal growth process. The microstructure of the membranes was examined by scanning electron microscopy (SEM). The permeation study with a single gas, nitrogen (N2) was performed through the membranes. For the surface modified support, a more surface coverage of the seed crystals on the porous support was observed resulting in a relatively higher dense packing of the crystals during secondary crystal growth process compared to that obtained from the unmodified support. The membrane developed on surface modified support rendered lower permeance value i.e. 9 × 10-7 mol m-2 s-1 Pa-1 of N2 compared to that formed on the unmodified support which gave permeance value of 20 × 10-7 mol m-2 s-1 Pa-1 of N2.

    The rapid development of spatial information technology has promoted a large variety of applications. The use of diverse,datasets in these applications has often been limited to single-platform analysis and distribution. Recent improvements in networking capabilities have led to the possibility of cross-platform access to geographical information and improved interoperability. To promote access to various databases and limit unsecured use of datasets across networks, spatial data browsers have been developed to allow simple analysis of data void of permanent update. Furthermore, applicable network configurations have greatly improved dissemination of views of existing data and individual use of distributed heterogeneous databases. Various user interfaces and networking applications can be combined to maximize data flow between storage media and data browsing software. This paper reviews the use of such distributed data browsing systems and the characteristics of platform-specific access and performance. Distinct discussions will review both geographical browser interface and networking services components. The selection of networking and software solutions was based on the development of a data browsing system for a twenty-user environment of mixed platforms (Unix, DOS, and Macintosh). Seventy percent of the user environment, however, was Macintosh-based.

  12. ROOT I/O in Javascript - Reading ROOT files in a browser

    CERN Document Server

    CERN. Geneva

    2012-01-01

    A JavaScript version of the ROOT I/O subsystem is being developed, in order to be able to browse (inspect) ROOT files in a platform independent way. This allows the content of ROOT files to be displayed in most web browsers, without having to install ROOT or any other software on the server or on the client. This gives a direct access to ROOT files from new (e.g. portable) devices in a light way. It will be possible to display simple graphical objects such as histograms and graphs (TH1, TH2, TH3, TProfile, TGraph, ...). The rendering will first be done with an external JavaScript graphic library, before investigating a way to produce graphics closer to what ROOT supports on other platforms (X11, Windows).

  13. A model to compare performance of space and ground network support of low-Earth orbiters

    Science.gov (United States)

    Posner, E. C.

    1992-01-01

    This article compares the downlink performance in a gross average sense between space and ground network support of low-Earth orbiters. The purpose is to assess what the demand for DSN support of future small, low-cost missions might be, if data storage for spacecraft becomes reliable enough and small enough to support the storage requirements needed to enable support only a fraction of the time. It is shown that the link advantage of the DSN over space reception in an average sense is enormous for low-Earth orbiters. The much shorter distances needed to communicate with the ground network more than make up for the speedup in data rate needed to compensate for the short contact times with the DSN that low-Earth orbiters have. The result is that more and more requests for DSN-only support of low-Earth orbiters can be expected.

  14. Implementing a Web Browser with Phishing Detection Techniques

    CERN Document Server

    Jain, Aanchal

    2011-01-01

    Phishing is the combination of social engineering and technical exploits designed to convince a victim to provide personal information, usually for the monetary gain of the attacker. Phishing has become the most popular practice among the criminals of the Web. Phishing attacks are becoming more frequent and sophisticated. The impact of phishing is drastic and significant since it can involve the risk of identity theft and financial losses. Phishing scams have become a problem for online banking and e-commerce users. In this paper we propose a novel approach to detect phishing attacks. We implemented a prototype web browser which can be used as an agent and processes each arriving email for phishing attacks. Using email data collected over a period time we demonstrate data that our approach is able to detect more phishing attacks than existing schemes.

  16. A Hybrid Web Browser Architecture for Mobile Devices

    Directory of Open Access Journals (Sweden)

    CHO, J.

    2014-08-01

    Full Text Available Web browsing on mobile networks is slow in comparison to wired or Wi-Fi networks. Particularly, the connection establishment phase including DNS lookups and TCP handshakes takes a long time on mobile networks due to its long round-trip latency. In this paper, we propose a novel web browser architecture that aims to improve mobile web browsing performance. Our approach delegates the connection establishment and HTTP header field delivery tasks to a dedicated proxy server located at the joint point between the WAN and mobile network. Since the traffic for the connection establishment and HTTP header fields delivery passes only through the WAN between the proxy and web servers, our approach significantly reduces both the number and size of packets on the mobile network. Our evaluation showed that the proposed scheme reduces the number of mobile network packets by up to 42% and, consequently, the average page loading time is shortened by up to 52%.

  17. The Small Bodies Imager Browser --- finding asteroid and comet images without pain

    Science.gov (United States)

    Palmer, E.; Sykes, M.; Davis, D.; Neese, C.

    2014-07-01

    To facilitate accessing and downloading spatially resolved imagery of asteroids and comets in the NASA Planetary Data System (PDS), we have created the Small Bodies Image Browser. It is a HTML5 webpage that runs inside a standard web browser needing no installation (http://sbn.psi.edu/sbib/). The volume of data returned by spacecraft missions has grown substantially over the last decade. While this wealth of data provides scientists with ample support for research, it has greatly increased the difficulty of managing, accessing and processing these data. Further, the complexity necessary for a long-term archive results in an architecture that is efficient for computers, but not user friendly. The Small Bodies Image Browser (SBIB) is tied into the PDS archive of the Small Bodies Asteroid Subnode hosted at the Planetary Science Institute [1]. Currently, the tool contains the entire repository of the Dawn mission's encounter with Vesta [2], and we will be adding other datasets in the future. For Vesta, this includes both the level 1A and 1B images for the Framing Camera (FC) and the level 1B spectral cubes from the Visual and Infrared (VIR) spectrometer, providing over 30,000 individual images. A key strength of the tool is providing quick and easy access of these data. The tool allows for searches based on clicking on a map or typing in coordinates. The SBIB can show an entire mission phase (such as cycle 7 of the Low Altitude Mapping Orbit) and the associated footprints, as well as search by image name. It can focus the search by mission phase, resolution or instrument. Imagery archived in the PDS are generally provided by missions in a single or narrow range of formats. To enhance the value and usability of this data to researchers, SBIB makes these available in these original formats as well as PNG, JPEG and ArcGIS compatible ISIS cubes [3]. Additionally, we provide header files for the VIR cubes so they can be read into ENVI without additional processing. Finally

    2011-03-01

    Full Text Available Abstract Background The concurrent release of rice genome sequences for two subspecies (Oryza sativa L. ssp. japonica and Oryza sativa L. ssp. indica facilitates rice studies at the whole genome level. Since the advent of high-throughput analysis, huge amounts of functional genomics data have been delivered rapidly, making an integrated online genome browser indispensable for scientists to visualize and analyze these data. Based on next-generation web technologies and high-throughput experimental data, we have developed Rice-Map, a novel genome browser for researchers to navigate, analyze and annotate rice genome interactively. Description More than one hundred annotation tracks (81 for japonica and 82 for indica have been compiled and loaded into Rice-Map. These pre-computed annotations cover gene models, transcript evidences, expression profiling, epigenetic modifications, inter-species and intra-species homologies, genetic markers and other genomic features. In addition to these pre-computed tracks, registered users can interactively add comments and research notes to Rice-Map as User-Defined Annotation entries. By smoothly scrolling, dragging and zooming, users can browse various genomic features simultaneously at multiple scales. On-the-fly analysis for selected entries could be performed through dedicated bioinformatic analysis platforms such as WebLab and Galaxy. Furthermore, a BioMart-powered data warehouse "Rice Mart" is offered for advanced users to fetch bulk datasets based on complex criteria. Conclusions Rice-Map delivers abundant up-to-date japonica and indica annotations, providing a valuable resource for both computational and bench biologists. Rice-Map is publicly accessible at http://www.ricemap.org/, with all data available for free downloading.

    Mathias Kuhring

    Full Text Available Proteogenomic approaches have gained increasing popularity, however it is still difficult to integrate mass spectrometry identifications with genomic data due to differing data formats. To address this difficulty, we introduce iPiG as a tool for the integration of peptide identifications from mass spectrometry experiments into existing genome browser visualizations. Thereby, the concurrent analysis of proteomic and genomic data is simplified and proteomic results can directly be compared to genomic data. iPiG is freely available from https://sourceforge.net/projects/ipig/. It is implemented in Java and can be run as a stand-alone tool with a graphical user-interface or integrated into existing workflows. Supplementary data are available at PLOS ONE online.

    Full Text Available Background and aim: Postpartum period is an exclusive period after birth which can act as a potential stressor and could be accompanied with psychological disorders. Social support could play an important role in maternal mental health. Considering various stressors and different levels of social support for women, this study aimed to compare postpartum stressors as well as social support level between primiparous and multiparous women. Method: This descriptive comparative study was conducted on 400 primiparous and multiparous mothers who referred to urban health centers, Mashhad, Iran in 2011. They had no history of medical or psychological problems and had healthy term neonates who were 8-25 days old. The sampling was carried out through a multistage cluster sampling. Data were collected using modified Hung questionnaire of postpartum stressors, Helen questionnaire of anxiety and Hopkins social support questionnaire. Data were analyzed using descriptive analytic statistics by SPSS version 11. Results: The mean stress scores were 242.5±157.1 in primiparous and 28.8±179.8 in multiparous women. The main stressor of primiparous and multiparous women was neonate bathing and lower-back pain, respectively. The mean score of social support was 108.3±8.25 in the primiparous and 102.0±26.6 in multiparous women, which showed a significant difference between two groups (P=0.000. Conclusion: Various care programs are essential to support primiparous and multiparous mothers from different stressors that they face in postpartum period. It is also recommended to provid more information regarding the social support for the families.

    Full Text Available The purpose of this study was to test the support to undermined occlusal enamel provided by posterior restorative composite (FiltekTM P60, 3M Dental products USA, polyacid modified resin composite (F2000 compomer, 3M Dental products, USA., radiopaque silver alloy-glass ionomer cement (Miracle Mix. GC Corp, Tokyo, Japan and Glass Ionomer cement (Fuji IX GP. To test each material, 20 human permanent mandibular third molars were selected. The lingual cusps were removed and the dentin supporting the facial cusps was cut away, leaving a shell of enamel. Each group of prepared teeth was restored using the materials according to the manufacturer′s instructions. All the specimens were thermocycled (250 cycles, 6°C- 60°C, dwell time 30 seconds and then mounted on an acrylic base. Specimens were loaded evenly across the cusp tips at a crosshead speed of 5 mm /minute in Hounsfield universal testing machine until fracture occurred. Data obtained was analyzed using analysis of variance and Studentized- Newman- Keul′s range test. No significant differences were detected in the support provided by P-60, F 2000, Miracle Mix or Fuji IX GP groups. The support provided to undermined occlusal enamel by these materials was intermediate between no support and that provided by sound dentin. Without further development in dental material technology and evidence of its efficacy, restorative materials should not be relied upon to support undermined occlusal enamel to a level comparable to that provided by sound dentin.

    members. Conclusion: This analysis demonstrated that in all five partners state-of-the-art preventative mental healthcare was included in the last deployment in Afghanistan, including a positive approach towards strengthening the mental resilience, a focus on self-regulatory skills and self-empowerment, and several initiatives that were well-integrated in a military context. These initiatives were partly/completely implemented by the military/colleagues/supervisors and applicable during several phases of the deployment cycle. Important new developments in operational mental health support are recognition of the role of social leadership and enhancement of operational peer support. This requires awareness of mental problems that will contribute to reduction of the barriers to care in case of problems. Finally, comparing mental health support services across countries can contribute to optimal preparation for the challenges of military deployment.

    Full Text Available Treadmill walking and running using a supportive harness has been used as a training method to rehabilitate injured patients' walking or running gait. Comparison of full weight support (FWS and body weight support (BWS kinematic measures in competitive runners has received little attention. The purpose of this study was to compare selected FWS to BWS kinematic measures in healthy competitive runners. Ten male runners (age = 21.4 ± 1.5 years with a training regimen averaging 64 km per week at 3.8 m·s-1 participated. All participants ran three 3-minute trials. The randomized trial conditions were: FWS, 20% BWS, and 40% BWS. All conditions were videotaped with 2 cameras and a 21-point, 3-D model was generated for analysis. From the position-time data, cycle length (CL, cycle frequency (CF, time of contact (TC, hip-, knee-, ankle- range of motion in degrees (H-ROM, K-ROM, and A-ROM, respectively, and vertical displacement of the center of mass (COM were derived and compared. With increasing support conditions, cycle length increased. Cycle frequency, hip and ankle angle ranges, and COM vertical displacement decreased (p 0.05. BWS running produced significant changes in selected kinematic measures. These changes may provide insight into runners' behavior when using BWS in training or recovery from competition. Additional investigation of BWS training affect with competitive runners would be recommended

    2001-07-01

    Full Text Available The diet of buffalo (Syncerus coffer and Burchell's zebra (Equus burchelli was investigated in the Addo Elephant National Park to test the hypothesis that the shortage of grass associated with thicket vegetation results in grazers increasing the proportion of dicotyledonous plant species in their diet. Diet composition, estimated from faecal analysis, indicated that 19 and 21 plant species were identified in the faeces of zebra and buffalo, respectively. Buffalo proved to have a higher percentage dicotyledonous (28.1 vs. 8.5 and lower percentage monocotyledonous (71.9 vs. 91.5 species in their diet than zebra. The grass Eragrostis curvula was found to be the dominant food item for both buffalo (18 of diet and zebra (39 of diet during the period of study. The present study indicated that a great proportion of the buffalo diet does in fact consist of grass, thereby refuting the perception that the Addo buffalo are primarily browsers. Both buffalo and zebra are specialised grazers and unsuited to a diet of browse. The probability of dietary shift by these grazers in the grass limited thicket vegetation is therefore challenged.

  13. Mining plant genome browsers as a means for efficient connection of physical, genetic and cytogenetic mapping: an example using soybean

    Directory of Open Access Journals (Sweden)

    Luis C. Belarmino

    2012-01-01

    Full Text Available Physical maps are important tools to uncover general chromosome structure as well as to compare different plant lineages and species, helping to elucidate genome structure, evolution and possibilities regarding synteny and colinearity. The increasing production of sequence data has opened an opportunity to link information from mapping studies to the underlying sequences. Genome browsers are invaluable platforms that provide access to these sequences, including tools for genome analysis, allowing the integration of multivariate information, and thus aiding to explain the emergence of complex genomes. The present work presents a tutorial regarding the use of genome browsers to develop targeted physical mapping, providing also a general overview and examples about the possibilities regarding the use of Fluorescent In Situ Hybridization (FISH using bacterial artificial chromosomes (BAC, simple sequence repeats (SSR and rDNA probes, highlighting the potential of such studies for map integration and comparative genetics. As a case study, the available genome of soybean was accessed to show how the physical and in silico distribution of such sequences may be compared at different levels. Such evaluations may also be complemented by the identification of sequences beyond the detection level of cytological methods, here using members of the aquaporin gene family as an example. The proposed approach highlights the complementation power of the combination of molecular cytogenetics and computational approaches for the anchoring of coding or repetitive sequences in plant genomes using available genome browsers, helping in the determination of sequence location, arrangement and number of repeats, and also filling gaps found in computational pseudochromosome assemblies.

  15. Comparing the innovation effects of support schemes for renewable electricity technologies: A function of innovation approach

    International Nuclear Information System (INIS)

    The aim of this paper is to provide a comparative assessment of the innovation effects of instruments which support the diffusion of renewable electricity technologies with a functions-oriented technological innovation system perspective. The paper provides a link between two major streams of the literature: the functions of innovation systems and the literature on renewable electricity support schemes. We show that, when a functional perspective is adopted, feed-in tariffs are likely to be superior to other policy instruments (quotas with tradable green certificates and tendering), although they still need to be complemented with other instruments, most importantly, direct R and D support. Furthermore, those innovation effects are affected by the specific design elements of the instruments chosen. - Highlights: ► A comparison of the innovation effects of instruments for the diffusion of renewable technologies. ► A functions-oriented technological innovation system perspective. ► A link between the functions of innovation systems and the literature on renewable electricity support schemes. ► Feed-in tariffs are likely to be superior to other instruments. ► Innovation effects are affected by the specific design elements of instruments.

    Full Text Available Effectively facilitating the growth of learners demonstrates prudent stewardship (Galatians 6:10; Genesis 2:15. As wise stewards of what God has entrusted to them, Christian educators are challenged to identify factors critical for supporting students’ learning in whatever environment they are teaching. When teaching in the online environment, this includes adopting technological applications to support learning. This study compared the use of two technological applications and their affect on student learning. Findings provided evidence that online graduate learners who used the combination of a content management system and e-conferencing system reported significantly higher perceptions of learning than learners who used only the content management system. Additional findings were not significant.

  17. Comparative Investigation of Benzene Steam Reforming over Spinel Supported Rh and Ir Catalysts

    In a combined experimental and first-principles density functional theory (DFT) study, benzene steam reforming (BSR) over MgAl2O4 supported Rh and Ir catalysts was investigated. Experimentally, it has been found that both highly dispersed Rh and Ir clusters (1-2 nm) on the MgAl2O4 spinel support are stable during the BSR in the temperature range of 700-850˚C. Compared to the Ir/MgAl2O4 catalyst, the Rh/MgAl2O4 catalyst is more active with higher benzene turnover frequency and conversion. At typical steam conditions with the steam-to-carbon ratio > 12, the benzene conversion is only a weak function of the H2O concentration in the feed. This suggests that the initial benzene decomposition step rather than the benzene adsorption is most likely the rate-determined step in BSR over supported Rh and Ir catalysts. In order to understand the differences between the two catalysts, we followed with a comparative DFT study of initial benzene decomposition pathways over two representative model systems for each supported metal (Rh and Ir) catalysts. A periodic terrace (111) surface and an amorphous 50-atom metal cluster with a diameter of 1.0 nm were used to represent the two supported model catalysts under low and high dispersion conditions. Our DFT results show that the decreasing catalyst particle size enhances the benzene decomposition on supported Rh catalysts by lowering both C-C and C-H bond scission. The activation barriers of the C-C and the C-H bond scission decrease from 1.60 and 1.61 eV on the Rh(111) surface to 1.34 and 1.26 eV on the Rh50 cluster. For supported Ir catalysts, the decreasing particle size only affects the C-C scission. The activation barrier of the C-C scission of benzene decreases from 1.60 eV on the Ir(111) surface to 1.35 eV on the Ir50 cluster while the barriers of the C-H scission are practically the same. The experimentally measured higher BSR activity on the supported highly dispersed Rh catalyst can be rationalized by the thermodynamic

    2014-07-01

    The importance in promoting, sustaining industries, manufacturing systems and economy through reliability measurement has become an area of interest. The profit of a system may be enhanced using highly reliable structural design of the system or subsystem of higher reliability. On improving the reliability and availability of a system, the production and associated profit will also increase. Reliability, availability and profit are some of the most important factors in any successful industry and manufacturing settings. In this paper, we compare three different repairable redundant systems using an external supporting device for operation based on the profit. Explicit expressions for the busy period of repairmen, steady-state availability and profit function are derived using linear first-order differential equations. Furthermore, we compare the profit for the three systems and find that system I is more profitable than systems II and III.

  1. A Policy Based Approach for the Management of Web Browser Resources to Prevent Anonymity Attacks in Tor

    Science.gov (United States)

    Navarro-Arribas, Guillermo; Garcia-Alfaro, Joaquin

    Web browsers are becoming the universal interface to reach applications and services related with these systems. Different browsing contexts may be required in order to reach them, e.g., use of VPN tunnels, corporate proxies, anonymisers, etc. By browsing context we mean how the user browsers the Web, including mainly the concrete configuration of its browser. When the context of the browser changes, its security requirements also change. In this work, we present the use of authorisation policies to automatise the process of controlling the resources of a Web browser when its context changes. The objective of our proposal is oriented towards easing the adaptation to the security requirements of the new context and enforce them in the browser without the need for user intervention. We present a concrete application of our work as a plug-in for the adaption of security requirements in Mozilla/Firefox browser when a context of anonymous navigation through the Tor network is enabled.

    Full Text Available The hacking is the greatest problem in the wireless local area network (WLAN. Many algorithms like DES, 3DES, AES,UMARAM, RC6 and UR5 have been used to prevent the outside attacks to eavesdrop or prevent the data to be transferred to the end-user correctly. We have proposed a Web programming language to be analyzed with five Web browsers in term of their performances to process the encryption of the programming language’s script with the Web browsers. This is followed by conducting tests simulation in order to obtain the best encryption algorithm versus Web browser. The results of the experimental analysis are presented in the form of graphs. We finally conclude on the findings that different algorithms perform differently to different Web browsers like Internet Explorer, Mozilla Firefox, Opera and Netscape Navigator. Hence, we now determine which algorithm works best and most compatible with which Web browser.A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as encryption/decryption speed in the different web Browsers. Experimental results are given to demonstrate the effectiveness of each algorithm.

    The objective of this study is to compare incineration and composting in a Mars-based advanced life support (ALS) system. The variables explored include waste pre-processing requirements, reactor sizing and buffer capacities. The study incorporates detailed mathematical models of biomass production and waste processing into an existing dynamic ALS system model. The ALS system and incineration models (written in MATLAB/SIMULINK(c)) were developed at the NASA Ames Research Center. The composting process is modeled using first order kinetics, with different degradation rates for individual waste components (carbohydrates, proteins, fats, cellulose and lignin). The biomass waste streams are generated using modified "Eneray Cascade" crop models, which use light- and dark-cycle temperatures, irradiance, photoperiod, [CO2], planting density, and relative humidity as model inputs. The study also includes an evaluation of equivalent system mass (ESM).

    2013-07-01

    Full Text Available Mobile technologies have helped establish new channels of communication among learners and instructors, potentially providing greater access to course information, and promoting easier access to course activities and learner motivation in online learning environments. The paper compares motivation between groups of learners being taught through an online course based on an e-learning system with and without the support of mobile communication tools, respectively. These tools, which are implemented on a mobile phone, extend the use of the existing Moodle learning management system (LMS under the guidance of a mobile communication tools framework. This framework is considered to be effective in promoting learner motivation and encouraging interaction between learners and instructors as well as among learner peers in online learning environments. A quasi-experimental research design was used to empirically investigate the influence of these tools on learner motivation using subjective assessment (for attention, relevance, confidence, satisfaction, and social ability and objective assessment (for disengagement, engagement, and academic performance. The results indicate that the use of the tools was effective in improving learner motivation, especially in terms of the attention and engagement variables. Overall, there were statistically significant differences in subjective motivation, with a higher level achieved by experimental-group learners (supported by the tools than control-group learners (unsupported by the tools.

  10. CDAPubMed: a browser extension to retrieve EHR-based biomedical literature

    Directory of Open Access Journals (Sweden)

    Perez-Rey David

    2012-04-01

    Full Text Available Abstract Background Over the last few decades, the ever-increasing output of scientific publications has led to new challenges to keep up to date with the literature. In the biomedical area, this growth has introduced new requirements for professionals, e.g., physicians, who have to locate the exact papers that they need for their clinical and research work amongst a huge number of publications. Against this backdrop, novel information retrieval methods are even more necessary. While web search engines are widespread in many areas, facilitating access to all kinds of information, additional tools are required to automatically link information retrieved from these engines to specific biomedical applications. In the case of clinical environments, this also means considering aspects such as patient data security and confidentiality or structured contents, e.g., electronic health records (EHRs. In this scenario, we have developed a new tool to facilitate query building to retrieve scientific literature related to EHRs. Results We have developed CDAPubMed, an open-source web browser extension to integrate EHR features in biomedical literature retrieval approaches. Clinical users can use CDAPubMed to: (i load patient clinical documents, i.e., EHRs based on the Health Level 7-Clinical Document Architecture Standard (HL7-CDA, (ii identify relevant terms for scientific literature search in these documents, i.e., Medical Subject Headings (MeSH, automatically driven by the CDAPubMed configuration, which advanced users can optimize to adapt to each specific situation, and (iii generate and launch literature search queries to a major search engine, i.e., PubMed, to retrieve citations related to the EHR under examination. Conclusions CDAPubMed is a platform-independent tool designed to facilitate literature searching using keywords contained in specific EHRs. CDAPubMed is visually integrated, as an extension of a widespread web browser, within the standard

  11. Comparing Virtual and Physical Robotics Environments for Supporting Complex Systems and Computational Thinking

    Berland, Matthew; Wilensky, Uri

    2015-10-01

    Both complex systems methods (such as agent-based modeling) and computational methods (such as programming) provide powerful ways for students to understand new phenomena. To understand how to effectively teach complex systems and computational content to younger students, we conducted a study in four urban middle school classrooms comparing 2-week-long curricular units—one using a physical robotics participatory simulation and one using a virtual robotics participatory simulation. We compare the two units for their effectiveness in supporting students' complex systems thinking and computational thinking skills. We find that while both units improved student outcomes to roughly the same extent, they engendered different perspectives on the content. That is, students using the physical system were more likely to interpret situations from a bottom-up ("agent") perspective, and students using the virtual system were more likely to employ a top-down ("aggregate") perspective. Our outcomes suggest that the medium of students' interactions with systems leads to differences in their learning from and about those systems. We explore the reasons for and effects of these differences, challenges in teaching this content, and student learning gains. The paper contributes operationalizable definitions of complex systems perspectives and computational perspectives and provides both a theoretical framework for and empirical evidence of a relationship between those two perspectives.

  12. Tamoxifen compared to best supportive care in advanced hepatocelluar carcinoma: A retrospective matched-cohort study

    International Nuclear Information System (INIS)

    Hepatocelluar carcinoma (HCC) is a common cancer worldwide as well as in Egypt with hepatitis B and C, alcohol and aflatoxins being the commonest risk factors. Tamoxifen was initially reported to confer a marginal survival benefit in advanced HCC. However, later reports declined any benefit. Objective: To study the impact of tamoxifen on overall survival (OS) compared to best supportive care (BSC) in Egyptian patients with advanced HCC. Methods: This retrospective matched-cohort study was conducted at Tanta Cancer Center (TCC), Egypt where 116 advanced HCC cases treated with tamoxifen were compared to TNM stage and Child-Pugh class matched 116 HCC cases who received BSC. Results: The median OS in the tamoxifen group was 9.3 months (95% confidence interval [Cl], 6.7- 11.9 months) compared to 8.7 months (95%CI, 6.8-10.6) in the BSC group (p = 0.758). With univariate analyses, it was shown that absence of fatigue, Child-Pugh class A, single tumors, less advanced tumors (T2), and absence of metastases (M0), had significantly better OS than their counterparts. Multivariate analysis showed that absence of fatigue, Child-Pugh class A and T2 tumors were independent prognostic factors affecting OS. Tamoxifen produced partial response and clinical stabilization in one% and 16% of cases, respectively. The median PFS with tamoxifen was 7.2 months (95%CI, 5.2-9.5). Conclusions: Tamoxifen did not show any OS advantage in Egyptian patients with advanced HCC. Use of this drug is discouraged

    Abstract Background Candida species are the most common cause of opportunistic fungal infection worldwide. Recent sequencing efforts have provided a wealth of Candida genomic data. We have developed the Candida Gene Order Browser (CGOB), an online tool that aids comparative syntenic analyses of Candida species. CGOB incorporates all available Candida clade genome sequences including two Candida albicans isolates (SC5314 and WO-1) and 8 closely related species (Candida dubliniensis, Candida tropicalis, Candida parapsilosis, Lodderomyces elongisporus, Debaryomyces hansenii, Pichia stipitis, Candida guilliermondii and Candida lusitaniae). Saccharomyces cerevisiae is also included as a reference genome. Results CGOB assignments of homology were manually curated based on sequence similarity and synteny. In total CGOB includes 65617 genes arranged into 13625 homology columns. We have also generated improved Candida gene sets by merging\\/removing partial genes in each genome. Interrogation of CGOB revealed that the majority of tandemly duplicated genes are under strong purifying selection in all Candida species. We identified clusters of adjacent genes involved in the same metabolic pathways (such as catabolism of biotin, galactose and N-acetyl glucosamine) and we showed that some clusters are species or lineage-specific. We also identified one example of intron gain in C. albicans. Conclusions Our analysis provides an important resource that is now available for the Candida community. CGOB is available at http:\\/\\/cgob.ucd.ie.

  14. Outdated document retrieved using a web browser, Hanford site, USA. Annex II-3

    International Nuclear Information System (INIS)

    While workers have an obligation to ensure that they are using the latest version of a document, they generally assume that they will receive the latest approved version when accessing a document from the web. This is typically a valid assumption because the Hanford site default browser setting forces the data to be refreshed each time a web page is accessed. In this case, a procedure user's browser setting had been changed from the default setting. As a result, they unknowingly accessed an outdated procedure because the older version had been cached on their system by the web browser. Site administrators should consider restricting users' ability to change browser settings from the configuration that forces a refresh procedure every time a web page is visited. Implementing a system to periodically reset them to the default setting is another option. For web sites where referenced documents change on a frequent basis, changes can be implemented to prevent workstations from caching information. Such changes will force all users accessing that web site to obtain the latest versions of documents regardless of the client browser setting. Web authors and those responsible for reference web servers (e.g. procedure web sites) should review the information in the technical supplement, and implement the appropriate techniques listed there for preventing documents from being stored in the user's cache

    Background Semantically-enriched browsing has enhanced the browsing experience by providing contextualised dynamically generated Web content, and quicker access to searched-for information. However, adoption of Semantic Web technologies is limited and user perception from the non-IT domain sceptical. Furthermore, little attention has been given to evaluating semantic browsers with real users to demonstrate the enhancements and obtain valuable feedback. The Sealife project investigates semantic browsing and its application to the life science domain. Sealife's main objective is to develop the notion of context-based information integration by extending three existing Semantic Web browsers (SWBs) to link the existing Web to the eScience infrastructure. Methods This paper describes a user-centred evaluation framework that was developed to evaluate the Sealife SWBs that elicited feedback on users' perceptions on ease of use and information findability. Three sources of data: i) web server logs; ii) user questionnaires; and iii) semi-structured interviews were analysed and comparisons made between each browser and a control system. Results It was found that the evaluation framework used successfully elicited users' perceptions of the three distinct SWBs. The results indicate that the browser with the most mature and polished interface was rated higher for usability, and semantic links were used by the users of all three browsers. Conclusion Confirmation or contradiction of our original hypotheses with relation to SWBs is detailed along with observations of implementation issues. PMID:19796398

  16. LCA and external costs in comparative assessment of electricity chains. Decision support for sustainable electricity provision?

    International Nuclear Information System (INIS)

    The provision of energy and electricity plays an important role in a country's economic and environmental performance and the sustainability of its development. Sustainable development of the energy and electricity sector depends on finding ways of meeting energy service demands of the present generation that are economically viable, environmentally sound, and socially acceptable and do not jeopardize the ability of future generations to meet their own energy needs. Life Cycle Assessment (LCA) and external cost valuation are considered to offer opportunities to assist energy policy in a comprehensive comparative evaluation of electricity supply options with regard to the different dimensions of sustainable energy provision as well as in the implementation of appropriate internalization strategies. The paper addresses life cycle assessment and external cost analysis carried out for selected electricity systems of interest under German conditions. Results from a comprehensive comparative assessment of various electricity supply options with regard to their environmental impacts, health risks, raw materials requirements as well as their resulting external cost will be summarised. The use of LCA based indicators for assessing the relative sustainability of electricity systems and the use of total (internal plus external) cost assessment as measure of economic and environmental efficiency of energy systems will be discussed. Open problems related to life cycle analysis of energy chains and the assessment of environmental damage costs are critically reviewed, to illustrate how in spite of existing uncertainties the state of the art results may provide helpful energy policy decision support. The paper starts with some remarks on what the concept of sustainability in terms of energy systems means. (author)

  17. Comparative evaluation of support vector machine classification for computer aided detection of breast masses in mammography

    International Nuclear Information System (INIS)

    False positive (FP) marks represent an obstacle for effective use of computer-aided detection (CADe) of breast masses in mammography. Typically, the problem can be approached either by developing more discriminative features or by employing different classifier designs. In this paper, the usage of support vector machine (SVM) classification for FP reduction in CADe is investigated, presenting a systematic quantitative evaluation against neural networks, k-nearest neighbor classification, linear discriminant analysis and random forests. A large database of 2516 film mammography examinations and 73 input features was used to train the classifiers and evaluate for their performance on correctly diagnosed exams as well as false negatives. Further, classifier robustness was investigated using varying training data and feature sets as input. The evaluation was based on the mean exam sensitivity in 0.05–1 FPs on normals on the free-response receiver operating characteristic curve (FROC), incorporated into a tenfold cross validation framework. It was found that SVM classification using a Gaussian kernel offered significantly increased detection performance (P = 0.0002) compared to the reference methods. Varying training data and input features, SVMs showed improved exploitation of large feature sets. It is concluded that with the SVM-based CADe a significant reduction of FPs is possible outperforming other state-of-the-art approaches for breast mass CADe. (paper)

  18. A comparative analysis of support vector machines and extreme learning machines.

    The theory of extreme learning machines (ELMs) has recently become increasingly popular. As a new learning algorithm for single-hidden-layer feed-forward neural networks, an ELM offers the advantages of low computational cost, good generalization ability, and ease of implementation. Hence the comparison and model selection between ELMs and other kinds of state-of-the-art machine learning approaches has become significant and has attracted many research efforts. This paper performs a comparative analysis of the basic ELMs and support vector machines (SVMs) from two viewpoints that are different from previous works: one is the Vapnik-Chervonenkis (VC) dimension, and the other is their performance under different training sample sizes. It is shown that the VC dimension of an ELM is equal to the number of hidden nodes of the ELM with probability one. Additionally, their generalization ability and computational complexity are exhibited with changing training sample size. ELMs have weaker generalization ability than SVMs for small sample but can generalize as well as SVMs for large sample. Remarkably, great superiority in computational speed especially for large-scale sample problems is found in ELMs. The results obtained can provide insight into the essential relationship between them, and can also serve as complementary knowledge for their past experimental and theoretical comparisons.

    Full Text Available Lack of security awareness amongst end users when dealing with online banking and electronic commerce leave many client side application vulnerabilities open. Thus, this is enables attackers to exploit the vulnerabilities and launch client-side attacks such as man-in-the-browser attack. The attack is designed to manipulate sensitive information via client’s application such as internet browser by taking advantage of the browser’s extension vulnerabilities. This attack exists due to lack of preventive measurement to detect any malicious changes on the client side platform. Therefore, in this paper we are proposing an enhanced remote authentication protocol with hardware based attestation and pseudonym identity enhancement to mitigate man-in-the-browser attacks as well as improving user identity privacy.

  4. Comparative Study Between Support Vector Machines And Neural Networks For Lithological Discrimination Using Hyper spectral Data

    International Nuclear Information System (INIS)

    Remote sensing hyper spectral data has many applications especially in the field of , earth science. Utilization of this technology has shown a rapid increase in many areas of economic and scientific significance. Hyper spectral sensors capture the detailed spectral signatures that uniquely characterize a great number of diverse surface materials. Classification, clustering, and visualization of these very high dimensional signatures need untraditional methods. Different approaches for spectral image interpretation have been studied using Artificial Neural Networks (ANNs) and Support Vector Machines (SVM) to meet the challenge of high dimensionality. The study used SVMs for geological mapping of hyper spectral imagery at Abu Zenima area, western Sinai, Egypt, the hyper spectral data has been captured in 2003 by Hyperion instrument on the United States Geological survey (USGS) Earth Observing 1 (EO-I) satellite. Precisely the study compares between the use of SVMs and a neural network built on the concept of SVMs, this network uses the Kernel-Adatron algorithm with the Gaussian kernel for the process of training. The SVMs also uses the Gaussian kernel with different bandwidths to enhance the performance of the interpretation process; the results are compared in details. The Neural Network was trained with four data sets, the first consists of 11310 samples, gives recognition rate of 84%, the second has 22620 samples, recognition rate was 91.5%; the third has 33930 samples, recognition rate was 94.6%; finally the fourth has 45240 samples, recognition rate of 99.2%. The previous results fall in comparison with the results of SVMs which use two algorithms for training the first is the one against one algorithm which gave a recognition rate of 84% for the first data set, a recognition rate of 76.9% for the second data set, a recognition rate of 95.2% for the third one and 98.5% for the fourth one. and the other is one against many algorithms which gave a recognition

    Monitoring applications are an extremely important task for the analysis and understanding geo-hazards, as well as for promptly recognizing and eventually warn about their potential paroxysmal evolution. Nowadays, a wide range of monitoring strategies and instruments can be applied in operative monitoring scenarios, and the technological evolution of last decades has considerably increased the possibility of managing complex multi-parametric networks. The effectiveness of a monitoring network in geo-hazard scenarios is usually directly associated to the type of instruments considered, the suitability and completeness of the monitoring network, and the frequency of acquisition of measurements (revisit time). However, especially during emergency scenarios, another fundamental parameter to consider is the possibility to achieve an easy and clear access to all the available information. The Geohazard Monitoring Group of CNR IRPI exploited the Google Earth® plugin to organize and present the information obtained d from a monitoring network installed on a landslide scenario in a straightforward fashion. The system restitutes all the available information on the monitored area as different layers, which are superimposed to the base map and digital elevation models provided by Google. The layers include data as raster (ortophotos, shaded relieves, etc.) and point information (position of instruments, monitored targets, etc.), as well as the most recent results obtained from the monitoring network in near real time. The resulting geo-browser is hosted on a dedicated website, where authorized end-users can select between several thematic visualizations. The system has been developed and tested in the Mont de La Saxe landslide scenario, a large instable slope located in the northwestern Italian. This new data exploitation modality has demonstrated to be an efficient tool to support the decision makers in particular during emergency phases.

    2011-07-01

    Full Text Available The Internet and World Wide Web being an essential part of everyone’s life, the users have become more conscious about their privacy. The user’s web privacy unfortunately, is not focused much by the current browsers. This paper focuses on the attacks which compromises user’s anonymity, grab user’s private data. It highlights the privacy attacks such as history sniffing, web beacons, browser fingerprinting. We focus on the protection of user’s information which is transferred over the network to the web server without the users consent rather than stealing attempts which fools the user and trap them to install malicious software which perform the theft, using social engineering techniques. A generic algorithm has been proposed in this paper which will stop the attacker from violating privacy. We have proposed a secure way of interaction between browser objects through browser API’S and the JavaScript. We developed an add-on which implements the proposed solution.

    2012-12-01

    The line between native and web applications is becoming increasingly blurred as modern web browsers are becoming powerful platforms on which applications can be run. Such applications are trivial to install and are readily extensible and easy to use. In an educational setting, web applications permit a way to deploy deploy tools in a highly-restrictive computing environment. The I2U2 collaboration has developed a browser-based event display for viewing events in data collected and released to the public by the CMS experiment at the LHC. The application itself reads a JSON event format and uses the JavaScript 3D rendering engine pre3d. The only requirement is a modern browser using HTML5 canvas. The event display has been used by thousands of high school students in the context of programs organized by I2U2, QuarkNet, and IPPOG. This browser-based approach to display of events can have broader usage and impact for experts and public alike.

    Sauer, J; Wastell, D G; Schmeink, C

    2009-03-01

    The study examined the influence of different types of enhanced system support on user performance during the management of a central heating system. A computer-based simulation of a central heating system, called CHESS V2.0, was used to model different interface options, providing different support facilities to the user (e.g., historical, predictive, and instructional displays). Seventy-five participants took part in the study and completed a series of operational scenarios under different support conditions. The simulation environment allowed the collection of performance measures (e.g., energy consumption), information sampling, and system control behaviour. Subjective user evaluations of various aspects of the system were also measured. The results showed performance gains for predictive displays whereas no such benefits were observed for the other display types. The data also revealed that status and predictive displays were valued most highly by users. The implications of the findings for designers of central heating systems are discussed. PMID:18433730

    Although folic acid is essential to numerous bodily functions, recent research indicates that a massive exposition to the vitamin could be a double-edged sword. In this study, the capacity of different caped mesoporous silica particles (i.e. Hollow Silica Shells, MCM-41, SBA-15 and UVM-7) to dose FA during its passage through the gastrointestinal tract has been evaluated. Results confirmed that the four capped materials were capable to hinder the delivery of FA at low pH (i.e. stomach) as well as able to deliver great amounts of the vitamin at neutral pH (i.e. intestine). Nevertheless, the encapsulation efficiency and the deliver kinetics differed among supports. While supports with large pore entrance exhibited an initial fast release, MCM-41, showed a sustained release along the time. This correlation between textural properties and release kinetics for each of the supports reveals the importance of a proper support selection as a strategy to control the delivery of active molecules.

Analysis of the concept maps suggests that both treatment groups significantly improved their understanding of evolution. However, the two groups developed different c...

    AEGSE Virtuoso Charting is an application that enables animated, real-time charting of telemetry streams of data from a rover. These automatically scaled charts are completely interactive, and allow users to choose the variables that they want to monitor. The charts can process data from streams with many variables. This application allows for the simultaneous viewing of up to four individually configured charts on a small touch-screen laptop. The charting application has been tested and found to be extremely robust during long operations. It was left running overnight, with incoming telemetry at 100 Hz, and it did not experience any signs of lost functionality or memory leaks. This robustness is critical for an application that will be used to support vital tests for the Mars Science Laboratory rover. The charting component also provides an interactive interface that allows the engineers to decide how many charts they want on their screen, and which attributes should be plotted on each chart. The application is optimized to make the charts on display take up as much of the available space as possible to maximize the use of the screen real estate. Engineers are also able to plot multiple attributes on the same chart, which enables them to observe the correlation between various attributes.

    This study evaluates the applicability of eight renewable electricity policy mechanisms for Southeast Asian electricity markets. It begins by describing the methodology behind 90 research interviews of stakeholders in the electricity industry. It then outlines four justifications given by respondents for government intervention to support renewables in Southeast Asia: unpriced negative externalities, counteracting subsidies for conventional energy sources, the public goods aspect of renewable energy, and the presence of non-technical barriers. The article develops an analytical framework to evaluate renewable portfolio standards, green power programs, public research and development expenditures, systems benefits charges, investment tax credits, production tax credits, tendering, and feed-in tariffs in Southeast Asia. It assesses each of these mechanisms according to the criteria of efficacy, cost effectiveness, dynamic efficiency, equity, and fiscal responsibility. The study concludes that one mechanism, feed-in tariffs, is both the most preferred by respondents and the only one that meets all criteria. (author)

  9. A 'compare and contrast' exercise: wrapping versus personalised external aortic root support (PEARS).

    2016-01-01

    Wrapping of the aorta and personalised external aortic root support (PEARS) both have the purpose of preventing further expansion of the ascending aorta in order to reduce the risk of aortic dissection and to spare the patient the disastrous consequences of aortic rupture. For the first time, Plonek and colleagues have reported systematically the CT appearances of a series of cases of wrapping. They illustrate the important finding that there are residual spaces between the aorta and the wrap. PEARS by contrast is intimately in contact with the aorta due to its personalised design and is fully incorporated due it construction from a porous mesh. A limitation of PEARS is that it is, of its nature, a planned and elective operation while wrapping can be undertaken during an emergency operation and can be used without prior planning as an intraoperative decision.

    2011-01-01

    The Lockheed Martin Aeronautics Company has been awarded several programs to modernize the aging C-5 military transport fleet. In order to ensure its continuation amidst budget cuts, it was important to engage the decision makers by providing an environment to analyze the benefits of the modernization program. This paper describes an interface that allows the user to change inputs such as the scenario airfields, take-off conditions, and reliability characteristics. The underlying logistics surrogate model was generated using data from a discrete-event simulation. Various visualizations such as intercontinental flight paths illustrated in 3D, have been created to aid the user in analyzing scenarios and performing comparative assessments for various output logistics metrics. The capability to rapidly and dynamically evaluate and compare scenarios was developed enabling real time strategy exploration and trade-offs.

In new research, Thomas Baker tests this, finding that a majority actually prefer resources be allocated to rehabilitative rather than punitive criminal justice policies. Further exploring why people prefer one approach to the other, he finds that living i...

    International Nuclear Information System (INIS)

    Many programs in experimental particle physics do not yet have a graphical interface, or demand strong platform and software requirements. With the most recent development of the VISPA project, we provide graphical interfaces to existing software programs and access to multiple computing clusters through standard web browsers. The scalable clientserver system allows analyses to be performed in sizable teams, and disburdens the individual physicist from installing and maintaining a software environment. The VISPA graphical interfaces are implemented in HTML, JavaScript and extensions to the Python webserver. The webserver uses SSH and RPC to access user data, code and processes on remote sites. As example applications we present graphical interfaces for steering the reconstruction framework OFFLINE of the Pierre-Auger experiment, and the analysis development toolkit PXL. The browser based VISPA system was field-tested in biweekly homework of a third year physics course by more than 100 students. We discuss the system deployment and the evaluation by the students.

  15. Integration of a browser based operator manual in the system environment of a process computer system

    International Nuclear Information System (INIS)

    The integration of a browser based operator manual in the system environment of a process computer system is an optimization of the operating procedure in the control room and a safety enhancement due to faster and error-free access to the manual contents. Several requirements by the authorities have to be fulfilled: the operating manual has to be available as hard copy, the format has to be true to original, protection against manipulation has to be provided, the manual content of the browser-based version and the hard copy have to identical, and the display presentation has to be consistent with ergonomic principals. The integration of the on-line manual in the surveillance process computer system provides the operator with the relevant comments to the surveillance signal. The described integration of the on-line manual is an optimization of the operator's everyday job with respect to ergonomics and safety (human performance).

    Full Text Available Web usage prediction has become a widely addressed topic with the huge proliferation of World Wide Web and computers. Most of the work done in this area of research is centered around prediction of what links the user is expected to visit next given his usage history, making suggestions for new web-sites he may be interested in and the like. We propose two algorithms to make browsers intelligent enough to gauge usage patterns. This algorithms are a blend of statistical and fuzzy logic techniques to gauge the surfing pattern of users, hence intelligently predicting the time ranges of likely user hits forparticular websites, speeding up the browsing experience by means of caching and preloading of predicted websites. Thus our design intends to make the browsers intelligent to speed up and better organize the browsing experience.

    2010-01-01

    This work presents the design and implementation of our Browser-based Massively Multiplayer Online Game, Living City, a simulation game fully developed at the University of Messina. Living City is a persistent and real-time digital world, running in the Web browser environment and accessible from users without any client-side installation. Today Massively Multiplayer Online Games attract the attention of Computer Scientists both for their architectural peculiarity and the close interconnection with the social network phenomenon. We will cover these two aspects paying particular attention to some aspects of the project: game balancing (e.g. algorithms behind time and money balancing); business logic (e.g., handling concurrency, cheating avoidance and availability) and, finally, social and psychological aspects involved in the collaboration of players, analyzing their activities and interconnections.

  1. Formats and Network Protocols for Browser Access to 2D Raster Data

    Science.gov (United States)

    Plesea, L.

    2015-12-01

    Tiled web maps in browsers are a major success story, forming the foundation of many current web applications. Enabling tiled data access is the next logical step, and is likely to meet with similar success. Many ad-hoc approaches have already started to appear, and something similar is explored within the Open Geospatial Consortium. One of the main obstacles in making browser data access a reality is the lack of a well-known data format. This obstacle also represents an opportunity to analyze the requirements and possible candidates, applying lessons learned from web tiled image services and protocols. Similar to the image counterpart, a web tile raster data format needs to have good intrinsic compression and be able to handle high byte count data types including floating point. An overview of a possible solution to the format problem, a 2D data raster compression algorithm called Limited Error Raster Compression (LERC) will be presented. In addition to the format, best practices for high request rate HTTP services also need to be followed. In particular, content delivery network (CDN) caching suitability needs to be part of any design, not an after-thought. Last but not least, HTML 5 browsers will certainly be part of any solution since they provide improved access to binary data, as well as more powerful ways to view and interact with the data in the browser. In a simple but relevant application, digital elevation model (DEM) raster data is served as LERC compressed data tiles which are used to generate terrain by a HTML5 scene viewer.

    A six-lobed membrane spanning cellulose synthesis complex (CSC) containing multiple cellulose synthase (CESA) glycosyltransferases mediates cellulose microfibril formation. The number of CESAs in the CSC has been debated for decades in light of changing estimates of the diameter of the smallest microfibril formed from the β-1,4 glucan chains synthesized by one CSC. We obtained more direct evidence through generating improved transmission electron microscopy (TEM) images and image averages of the rosette-type CSC, revealing the frequent triangularity and average cross-sectional area in the plasma membrane of its individual lobes. Trimeric oligomers of two alternative CESA computational models corresponded well with individual lobe geometry. A six-fold assembly of the trimeric computational oligomer had the lowest potential energy per monomer and was consistent with rosette CSC morphology. Negative stain TEM and image averaging showed the triangularity of a recombinant CESA cytosolic domain, consistent with previous modeling of its trimeric nature from small angle scattering (SAXS) data. Six trimeric SAXS models nearly filled the space below an average FF-TEM image of the rosette CSC. In summary, the multifaceted data support a rosette CSC with 18 CESAs that mediates the synthesis of a fundamental microfibril composed of 18 glucan chains. PMID:27345599

    Barth, Alexander; Watelet, Sylvain; Troupin, Charles; Beckers, Jean-Marie

    2015-04-01

    OceanBrowser is a web-based visualization tool for gridded oceanographic data sets. Those data sets are typically four-dimensional (longitude, latitude, depth and time). OceanBrowser allows one to visualize horizontal sections at a given depth and time to examine the horizontal distribution of a given variable. It also offers the possibility to display the results on an arbitrary vertical section. To study the evolution of the variable in time, the horizontal and vertical sections can also be animated. Vertical section can be generated by using a fixed distance from coast or fixed ocean depth. The user can customize the plot by changing the color-map, the range of the color-bar, the type of the plot (linearly interpolated color, simple contours, filled contours) and download the current view as a simple image or as Keyhole Markup Language (KML) file for visualization in applications such as Google Earth. The data products can also be accessed as NetCDF files and through OPeNDAP. Third-party layers from a web map service can also be integrated. OceanBrowser is used in the frame of the SeaDataNet project (http://gher-diva.phys.ulg.ac.be/web-vis/) and EMODNET Chemistry (http://oceanbrowser.net/emodnet/) to distribute gridded data sets interpolated from in situ observation using DIVA (Data-Interpolating Variational Analysis).

    Point cloud data, in the form of Light Detection and Ranging (LiDAR), RADAR, or semi-global matching (SGM) image processing, are rapidly becoming a foundational data type to quantify and characterize geospatial processes. Visualization of these data, due to overall volume and irregular arrangement, is often difficult. Technological advancement in web browsers, in the form of WebGL and HTML5, have made interactivity and visualization capabilities ubiquitously available which once only existed in desktop software. plas.io is an open source JavaScript application that provides point cloud visualization, exploitation, and compression features in a web-browser platform, reducing the reliance for client-based desktop applications. The wide reach of WebGL and browser-based technologies mean plas.io's capabilities can be delivered to a diverse list of devices -- from phones and tablets to high-end workstations -- with very little custom software development. These properties make plas.io an ideal open platform for researchers and software developers to communicate visualizations of complex and rich point cloud data to devices to which everyone has easy access.

  10. Nessi: An EEG-Controlled Web Browser for Severely Paralyzed Patients

    Directory of Open Access Journals (Sweden)

    Michael Bensch

    2007-01-01

    Full Text Available We have previously demonstrated that an EEG-controlled web browser based on self-regulation of slow cortical potentials (SCPs enables severely paralyzed patients to browse the internet independently of any voluntary muscle control. However, this system had several shortcomings, among them that patients could only browse within a limited number of web pages and had to select links from an alphabetical list, causing problems if the link names were identical or if they were unknown to the user (as in graphical links. Here we describe a new EEG-controlled web browser, called Nessi, which overcomes these shortcomings. In Nessi, the open source browser, Mozilla, was extended by graphical in-place markers, whereby different brain responses correspond to different frame colors placed around selectable items, enabling the user to select any link on a web page. Besides links, other interactive elements are accessible to the user, such as e-mail and virtual keyboards, opening up a wide range of hypertext-based applications.

  11. Systematic comparative and sensitivity analyses of additive and outranking techniques for supporting impact significance assessments

    International Nuclear Information System (INIS)

    Assessing the significance of environmental impacts is one of the most important and all together difficult processes of Environmental Impact Assessment. This is largely due to the multicriteria nature of the problem. To date, decision techniques used in the process suffer from two drawbacks, namely the problem of compensation and the problem of identification of the 'exact boundary' between sub-ranges. This article discusses these issues and proposes a methodology for determining the significance of environmental impacts based on comparative and sensitivity analyses using the Electre TRI technique. An application of the methodology for the environmental assessment of a Power Plant project within the Valencian Region (Spain) is presented, and its performance evaluated. It is concluded that contrary to other techniques, Electre TRI automatically identifies those cases where allocation of significance categories is most difficult and, when combined with sensitivity analysis, offers greatest robustness in the face of variation in weights of the significance attributes. Likewise, this research demonstrates the efficacy of systematic comparison between Electre TRI and sum-based techniques, in the solution of assignment problems. The proposed methodology can therefore be regarded as a successful aid to the decision-maker, who will ultimately take the final decision

  12. Evaluating ecological equivalence of created marshes: comparing structural indicators with stable isotope indicators of blue crab trophic support

    Science.gov (United States)

    Llewellyn, Chris; LaPeyre, Megan K.

    2010-01-01

    This study sought to examine ecological equivalence of created marshes of different ages using traditional structural measures of equivalence, and tested a relatively novel approach using stable isotopes as a measure of functional equivalence. We compared soil properties, vegetation, nekton communities, and δ13C and δ15N isotope values of blue crab muscle and hepatopancreas tissue and primary producers at created (5-24 years old) and paired reference marshes in SW Louisiana. Paired contrasts indicated that created and reference marshes supported equivalent plant and nekton communities, but differed in soil characteristics. Stable isotope indicators examining blue crab food web support found that the older marshes (8 years+) were characterized by comparable trophic diversity and breadth compared to their reference marshes. Interpretation of results for the youngest site was confounded by the fact that the paired reference, which represented the desired end goal of restoration, contained a greater diversity of basal resources. Stable isotope techniques may give coastal managers an additional tool to assess functional equivalency of created marshes, as measured by trophic support, but may be limited to comparisons of marshes with similar vegetative communities and basal resources, or require the development of robust standardization techniques.

  13. A comparative study of surface EMG classification by fuzzy relevance vector machine and fuzzy support vector machine

    International Nuclear Information System (INIS)

    We present a multiclass fuzzy relevance vector machine (FRVM) learning mechanism and evaluate its performance to classify multiple hand motions using surface electromyographic (sEMG) signals. The relevance vector machine (RVM) is a sparse Bayesian kernel method which avoids some limitations of the support vector machine (SVM). However, RVM still suffers the difficulty of possible unclassifiable regions in multiclass problems. We propose two fuzzy membership function-based FRVM algorithms to solve such problems, based on experiments conducted on seven healthy subjects and two amputees with six hand motions. Two feature sets, namely, AR model coefficients and room mean square value (AR-RMS), and wavelet transform (WT) features, are extracted from the recorded sEMG signals. Fuzzy support vector machine (FSVM) analysis was also conducted for wide comparison in terms of accuracy, sparsity, training and testing time, as well as the effect of training sample sizes. FRVM yielded comparable classification accuracy with dramatically fewer support vectors in comparison with FSVM. Furthermore, the processing delay of FRVM was much less than that of FSVM, whilst training time of FSVM much faster than FRVM. The results indicate that FRVM classifier trained using sufficient samples can achieve comparable generalization capability as FSVM with significant sparsity in multi-channel sEMG classification, which is more suitable for sEMG-based real-time control applications.

    2015-01-01

    The purpose of this study was to clinically and radiographically compare implant-connected and tooth-connected implant-supported fixed-detachable mandibular partial dentures. Twenty partially edentulous patients (age range: 25 to 50 years) with mandibular Kennedy Class II configurations were equally divided into two groups receiving a three-unit, fixed-detachable, screw-retained partial denture. Group 1 comprised patients with unilateral missing mandibular molars and premolars. Two implants were placed at the mandibular first premolar and first molar areas. Group 2 comprised patients with missing mandibular molars and second premolars. An implant was placed at the mandibular first molar area, the first premolar was prepared, and a coping was cemented to the tooth with permanent cement. Each case was evaluated clinically and radiographically at baseline (partial denture insertion) and after 6, 12, and 24 months. Data were collected and statistically analyzed using repeated-measures one-way and two-way analysis of variance tests. There was no statistically significant difference between the two groups (P > .05). The implant-tooth-supported prosthesis provided an equally predictable treatment option compared to the totally implant-supported prosthesis in terms of implant survival and loss of marginal bone.

    Full Text Available Abstract Background Inhalation of helium-oxygen (He/O2 mixtures has been explored as a means to lower the work of breathing of patients with obstructive lung disease. Non-invasive ventilation (NIV with positive pressure support is also used for this purpose. The bench experiments presented herein were conducted in order to compare simulated patient inspiratory effort breathing He/O2 with that breathing medical air, with or without pressure support, across a range of adult, obstructive disease patterns. Methods Patient breathing was simulated using a dual-chamber mechanical test lung, with the breathing compartment connected to an ICU ventilator operated in NIV mode with medical air or He/O2 (78/22 or 65/35%. Parabolic or linear resistances were inserted at the inlet to the breathing chamber. Breathing chamber compliance was also varied. The inspiratory effort was assessed for the different gas mixtures, for three breathing patterns, with zero pressure support (simulating unassisted spontaneous breathing, and with varying levels of pressure support. Results Inspiratory effort increased with increasing resistance and decreasing compliance. At a fixed resistance and compliance, inspiratory effort increased with increasing minute ventilation, and decreased with increasing pressure support. For parabolic resistors, inspiratory effort was lower for He/O2 mixtures than for air, whereas little difference was measured for nominally linear resistance. Relatively small differences in inspiratory effort were measured between the two He/O2 mixtures. Used in combination, reductions in inspiratory effort provided by He/O2 and pressure support were additive. Conclusions The reduction in inspiratory effort afforded by breathing He/O2 is strongly dependent on the severity and type of airway obstruction. Varying helium concentration between 78% and 65% has small impact on inspiratory effort, while combining He/O2 with pressure support provides an additive

  17. Probing public perceptions on energy: Support for a comparative, deep-probing survey design for complex issue domains

    International Nuclear Information System (INIS)

    Surveys of public attitudes have increasingly been criticized for being superficial and too fragmented to sufficiently represent views comprehensively within a complex issue domain. Attitudes are often assessed without context, and the scope of these surveys tends to be relatively narrow. With these concerns in mind, we developed a survey of adults in the United States that incorporated an approach that looks comparatively and in-depth at sub-issues within a larger policy domain, thereby probing deeper into individuals' attitudes than typically found. Our emphasis is on energy issues. As debates over energy issues like hydraulic fracturing, oil exploration, gas prices, and renewable energy rage, it is increasingly important to accurately and fully evaluate public attitudes. We present the results of this survey and evaluate the benefits of utilizing a sub-issue comparative, deep-probing survey instrument. - Highlights: • Comparing across energy types yields a stronger understanding of public opinions. • Stronger support for increased renewable energy than for increased natural gas use. • Stronger support for nuclear is stronger than for coal even though least favored technology

    Full Text Available In the recent years, everything is in web. It may be Organization’s administration software, Custom ERP application, Employee portals or Real estate portals. The Social networking sites like Face book, Twitter, MySpace which is a web application is been used by millions of users around the world. So web applications have become very popular among users. Hence they are observed and may be exploited by hackers. Researchers and industry experts state that the Cross-site Scripting (XSS is the one of the top most vulnerabilities in the web application. The cross-site scripting has become a common vulnerability of many web sites and web applications. XSS consists in the exploitation of input validation flaws, with the purpose of injecting arbitrary script code which is later executed at the web browser of the victim. According to OSWAP, Cross-site scripting attacks on web applications have experienced an important rise in recent year. This demands an efficient approach on the server side to protect the users of the application as the reason for the vulnerability primarily lies on the server side. The actual exploitation is within the victim’s web browser on the client-side. Therefore, an operator of a web application has only very limited evidence of XSS issues. However, there are many solutions for this vulnerability. But such techniques may degrade the performance of the system. In such scenarios challenge is to decide which method, platform, browser and middleware can be used to overcome the vulnerabilities, with reasonable performance over head to the system.

    2012-12-01

    The distribution of earthquakes is often easier to interpret in 3D, but most 3D visualization tools require the installation of specialized software and some practice in their use. To reduce this barrier for students and the general public, a pseudo-3D seismicity viewer has been developed which runs in a web browser as part of the IRIS Earthquake Browser (IEB). IEB is an interactive map for viewing earthquake epicenters all over the world, and is composed of a Google map, HTML, JavaScript and a fast earthquake hypocenter web service. The web service accesses seismic data at IRIS from the early 1960s until present. Users can change the region, the number of events, and the depth and magnitude ranges to display. Earthquakes may also be viewed as a table, or exported to various formats. Predefined regions can be selected and zoomed to, and bookmarks generally preserve whatever region and settings are in effect when bookmarked, allowing the easy sharing of particular "scenarios" with other users. Plate boundaries can be added to the display. The 3DV viewer displays events for the currently-selected IEB region in a separate window. They can be rotated and zoomed, with a fast response for plots of up to several thousand events. Rotation can be done manually by dragging or automatically at a set rate, and tectonic plate boundaries turned on or off. 3DV uses a geographical projection algorithm provided by Gary Pavils and collaborators. It is written in HTML5, and is based on CanvasMol by Branislav Ulicny.; A region SE of Fiji, selected in IRIS Earthquake Browser. ; The same region as viewed in 3D Viewer.

    Background: Unwanted pregnancy induces adverse attitudes regarding pregnancy which is a natural event by increasing mental and socio-economic difficulties. Insufficient maternal care and low adjustment to parental role are known as consequences of unwanted pregnancy. Perceived social support and self-efficacy in pregnancy influence health related behaviors and may play a crucial role in adaptation to pregnancy; this study was conducted to examine and compare the self-efficacy and social support among two groups of women with wanted and unwanted pregnancy. Methods: This analytical descriptive research was conducted on 315 women referred to 13 health centers in the east and west of Ahvaz in 2011. Data were collected via random stratified sampling method through interview. The instrument of this study was a questionnaire in three distinct parts including demographic, modified Persian version of Vaux General social support (Chronbach`s alpha =0.80) and Persian version of self-efficacy scale (Chronbach`s alpha =0.80). Data were analyzed through independent t-test and ANOVA. A P<0.05 was considered significant. Results: The mean age of the subjects was 25.8±5.6; unwanted pregnancy occurred in 135 women (42.2%). The mean scores of social support in the two given groups with wanted and unwanted pregnancy were 26.62±4.16 and 22.28±7.57, respectively (P<0.001). Furthermore, the mean scores of self-efficacy for the wanted pregnancy group was 37.77±6.66 and for unwanted pregnancy group it was 31.03±6.31 (P<0.001). Women and their husbands’ age, the number of male offspring in family and marriage years were significantly different in the two groups (P<0.05). Conclusion: This study showed that unwanted pregnant women are more likely to be exposed to low level of perceived social support and self-efficacy. Therefore more studies and interventions are recommended to be conducted to analyze the effect of family and friends’ supports on unwanted pregnant women’s perceived

    Full Text Available Abstract Background Multiple Sclerosis (MS is an incurable, chronic, potentially progressive and unpredictable disease of the central nervous system. The disease produces a range of unpleasant and debilitating symptoms, which can have a profound impact including disrupting activities of daily living, employment, income, relationships, social and leisure activities, and life goals. Adjusting to the illness is therefore particularly challenging. This trial tests the effectiveness of a Cognitive Behavioural intervention compared to Supportive Listening to assist adjustment in the early stages of MS. Methods/Design This is a two arm randomized multi-centre parallel group controlled trial. 122 consenting participants who meet eligibility criteria will be randomly allocated to receive either Cognitive Behavioral Therapy or Supportive Listening. Eight one hour sessions of therapy (delivered over a period of 10 weeks will be delivered by general nurses trained in both treatments. Self-report questionnaire data will be collected at baseline (0 weeks, mid-therapy (week 5 of therapy, post-therapy (15 weeks and at six months (26 weeks and twelve months (52 weeks follow-up. Primary outcomes are distress and MS-related social and role impairment at twelve month follow-up. Analysis will also consider predictors and mechanisms of change during therapy. In-depth interviews to examine participants' experiences of the interventions will be conducted with a purposively sampled sub-set of the trial participants. An economic analysis will also take place. Discussion This trial is distinctive in its aims in that it aids adjustment to MS in a broad sense. It is not a treatment specifically for depression. Use of nurses as therapists makes the interventions potentially viable in terms of being rolled out in the NHS. The trial benefits from incorporating patient input in the development and evaluation stages. The trial will provide important information about the

    Traumatic victimization and associated problems with posttraumatic stress disorder (PTSD) and affect dysregulation are prevalent among incarcerated women, but there is limited evidence to support psychotherapeutic interventions for these problems in this underserved population. A group psychotherapy designed to enhance affect regulation without trauma memory processing-Trauma Affect Regulation: Guide for Education and Therapy (TARGET)-was compared to a supportive group therapy (SGT) in a randomized clinical trial with 72 incarcerated women with full or partial PTSD. Both interventions achieved statistically significant reductions in PTSD and associated symptom severity and increased self-efficacy. Dropout rates for both interventions were low (forgiveness toward others who have caused harm in the past. Group therapy that teaches affect regulation may enhance incarcerated women's ability to achieve affective resolution (forgiveness) while also reducing their victimization-related PTSD and associated symptoms. Experiential-focused supportive group therapy also may reduce victimization-related PTSD and associated symptoms. Both group therapy approaches warrant further study with this vulnerable population.

  7. Comparative economic analysis of supporting policies for residential solar PV in the United States: Solar Renewable Energy Credit (SREC) potential

    International Nuclear Information System (INIS)

    Numerous studies and market reports suggest that the solar photovoltaic markets rely heavily, if not entirely, upon governmental support policies at present. Unlike in other countries where these policies are enacted at a national level, the 50 states in the US pursue different policies in an attempt to foster the growth of renewable energy, and specifically solar photovoltaics. This paper provides an economic and financial analysis of the US federal and state level policies in states with solar-targeted policies that have markets. After putting a value on SRECs, this study further compares solar carve-outs with other incentives including the federal tax credit, net metering, and state personal tax credits. Our findings show that SREC markets can certainly be strong, with New Jersey, Delaware, and Massachusetts having the most potential. Despite their strong potential as effective renewable policies, the lack of a guaranteed minimum and the uncertainty attached are major drawbacks of SREC markets. However, the leveraging of this high value offers hope that the policies will indeed stimulate residential solar photovoltaic markets. - Highlights: ► We measure solar support incentives in eight US states with set-asides that include SREC policies. ► Compare each financial incentive using DCF, NPV, IRR, and Present Value/Watt-capacity. ► Most US SREC markets have strong potential to stimulate solar photovoltaics. ► SREC success requires price floors to alleviate uncertainty issues. ► Private financial entities can leverage SRECs to provide necessary price floors.

    International Nuclear Information System (INIS)

    The purposes of this study were to construct an interactive atlas of the temporal bone using a web-browser and to provide a template for web-based teaching files, using free and shared applets and scripts on the internet. HRCT and MR images of the temporal bone including its normal anatomy, tumors, trauma, inflammation, anomalies and vascular diseases were used in this study. Acquired radiologic images were transformed to GIF/JPG formats and to achieve appropriate image quality, were retouched. Text and image files of normal anatomy and diseases were written by HTML. JavaScript and applets were inserted in the HTML files for the interactive display of images and texts. In order to review anatomic features and diseases, a search index was also attached to the last part of the file. Using interactive images and text, temporal bone anatomy and disorders were displayed. Scripts and applets were also useful for indicating specific points of interest when a mouse was placed over the anatomic sites. The atlas may be viewed in the form of a CD-ROM, or via the internet using any computer platform or web-browser. This web-based teaching file of the temporal bone offers dynamic and interactive education. It can be usefully employed as a template for the production of interactive educational materials, offering JavaScript and providing suitable input for classes. It can replace texts and imaging contents. (author)

  11. Seed dispersers, seed predators, and browsers act synergistically as biotic filters in a mosaic landscape.

    Regino Zamora

    Full Text Available In this study, we analize the functional influence of animals on the plants they interact with in a mediterranean mountain. We hypothesise that seed dispersers, seed predators, and browsers can act as biotic filters for plant communities. We analyse the combined effects of mutualistic (seed dispersal and antagonistic (seed predation, herbivory animal interactions in a mosaic landscape of Mediterranean mountains, basing our results on observational and experimental field. Most of the dispersed seeds came from tree species, whereas the population of saplings was composed predominantly of zoochorous shrub species. Seed predators preferentially consumed seeds from tree species, whereas seeds from the dominant fleshy-fruited shrubs had a higher probability of escaping these predators. The same pattern was repeated among the different landscape units by browsers, since they browsed selectively and far more intensely on tree-species saplings than on the surrounding shrubs. In synthesis, our work identifies the major biotic processes that appear to be favoring a community dominated by shrubs versus trees because seed dispersers, predators, and herbivores together favored shrub dispersal and establishment versus trees.

    1998-07-01

    The current version of the Global PACS software system uses a Java-based implementation of the Remote Consultation and Diagnosis (RCD) system. The Java RCD includes a multimedia consultation session between physicians that includes text, static image, image annotation, and audio data. The JAVA RCD allows 2-4 physicians to collaborate on a patient case. It allows physicians to join the session via WWW Java-enabled browsers or stand alone RCD application. The RCD system includes a distributed database archive system for archiving and retrieving patient and session data. The RCD system can be used for store and forward scenarios, case reviews, and interactive RCD multimedia sessions. The RCD system operates over the Internet, telephone lines, or in a private Intranet. A multimedia consultation session can be recorded, and then played back at a later time for review, comments, and education. A session can be played back using Java-enabled WWW browsers on any operating system platform. The JAVA RCD system shows that a case diagnosis can be captured digitally and played back with the original real-time temporal relationships between data streams. In this paper, we describe design and implementation of the RCD session playback.

    Full Text Available Abstract Web applications for biology and medicine often need to integrate data from Entrez services provided by the National Center for Biotechnology Information. However, direct access to Entrez from a web browser is not possible due to 'same-origin' security restrictions. The use of "Asynchronous JavaScript and XML" (AJAX to create rich, interactive web applications is now commonplace. The ability to access Entrez via AJAX would be advantageous in the creation of integrated biomedical web resources. We describe EntrezAJAX, which provides access to Entrez eUtils and is able to circumvent same-origin browser restrictions. EntrezAJAX is easily implemented by JavaScript developers and provides identical functionality as Entrez eUtils as well as enhanced functionality to ease development. We provide easy-to-understand developer examples written in JavaScript to illustrate potential uses of this service. For the purposes of speed, reliability and scalability, EntrezAJAX has been deployed on Google App Engine, a freely available cloud service.

    need to provide common workspace for analysis because the client is physically separated from a server. We solved the file format problem by extension of rules of OptionControlFile of Eos. Furthermore, to solve workspace problems, we have developed two type of system. The first system is to use only local environments. The user runs a web server provided by Eos, access to a web client through a web browser, and manipulate the local files with GUI on the web browser. The second system is employing PIONE (Process-rule for Input/Output Negotiation Environment), which is our developing platform that works under heterogenic distributed environment. The users can put their resources, such as microscopic images, text files and so on, into the server-side environment supported by PIONE, and so experts can write PIONE rule definition, which defines a workflow of image processing. PIONE run each image processing on suitable computers, following the defined rule. PIONE has the ability of interactive manipulation, and user is able to try a command with various setting values. In this situation, we contribute to auto-generation of GUI for a PIONE workflow.As advanced functions, we have developed a module to log user actions. The logs include information such as setting values in image processing, procedure of commands and so on. If we use the logs effectively, we can get a lot of advantages. For example, when an expert may discover some know-how of image processing, other users can also share logs including his know-hows and so we may obtain recommendation workflow of image analysis, if we analyze logs. To implement social platform of image processing for electron microscopists, we have developed system infrastructure, as well. PMID:25359837

  16. Governing new technology: A comparative analysis of government support for nanotechnology in the Netherlands and the United States

    Science.gov (United States)

    Eijmberts, Johannes

    This study examines this variance in national government support for nanotechnology---its shape, size, and policy priorities---by comparing the United States and the Netherlands. Our operating hypothesis is that national government support for nanotechnology development is driven not by the intrinsic nature of the technology but by longstanding structural and institutional arrangements. That is, in the U.S., pluralist political traditions and reliance on classical liberal market economics would suggest a detached national government approach, leaving any initiative to market actors. At the same time, legacies of corporatism in the Dutch political system and a tradition of greater direct government involvement in the national economy would suggest a government-led policy on nanotechnology development. The findings show otherwise. Early on, the U.S. government established the National Nanotechnology Initiative, an overarching federal mechanism to promote and coordinate nanotechnology development. Yet, despite its appearance of central direction and coordination, the NNI reflected pluralist arrangements by leaving ample autonomy for participating federal departments and agencies. The creation of the NNI was driven particularly by concerns of about foreign challenges to American global leadership in science and technology. In the Netherlands, by contrast, the path taken shows the legacy of Dutch corporatist practice---slow, incremental, and embedded in pre-existing institutional arrangements. The Dutch government initially took no directive role, relying instead on established links among universities, public research funding organizations, and industries to advance nanotechnology development in the Netherlands. However, over time, Dutch government involvement in nanotechnology grew to be more supportive, sizeable, comprehensive, and directive---particulary by requiring substantial investments in risk-related research as a condition for public funding and, notably, by

    2013-01-01

    The trajectory browser is a web-based tool developed at the NASA Ames Research Center for finding preliminary trajectories to planetary bodies and for providing relevant launch date, time-of-flight and (Delta)V requirements. The site hosts a database of transfer trajectories from Earth to planets and small-bodies for various types of missions such as rendezvous, sample return or flybys. A search engine allows the user to find trajectories meeting desired constraints on the launch window, mission duration and (Delta)V capability, while a trajectory viewer tool allows the visualization of the heliocentric trajectory and the detailed mission itinerary. The anticipated user base of this tool consists primarily of scientists and engineers designing interplanetary missions in the context of pre-phase A studies, particularly for performing accessibility surveys to large populations of small-bodies.

    Full Text Available Currently there are many different Identity Management Systems which differ in their architectures as well as use different protocols and serve different purposes and are extensively used by organisations to provide online services. With the remarkable growth of mobile phones in the last few years, both in number and computational power, more and more users are accessing an array of online services using their mobile phones. One of the major concerns for the user of mobile phones is the battery life which is limited and tends to run out quickly. Hence, efficiency in power consumption is a crucial factor for any system when it is accessed using a mobile phone. In this paper, we analyse the efficiency, in terms ofpower consumption, of different browsers in mobile phones and different Identity Management Systems when the mobile phones are used to access online services protected by those Identity Management Systems.

    The aim of the present study was to compare the efficacy, tolerability and patients' satisfaction after the use of oral dydrogesterone with vaginal micronized progesterone for luteal-phase support (LPS) among infertile women undergoing in vitro fertilization (IVF). A total of 210 women (aged 20-40 years old) with a history of infertility, who underwent controlled ovarian stimulation for fresh intra-cytoplasmic sperm injection-embryo transfer cycles, were included in the study. Consequently, they were randomized to receive LPS with dydrogesterone 20 mg twice daily (n = 96) or micronized progesterone 400 mg twice daily at the day of oocyte retrieval (n = 114). The clinical success rate (31% versus 33%; p = 0.888), miscarriage rate (5.0% versus 3.0%; p = 0.721), ongoing pregnancy rate (30.0% versus 30.0%; p = 1.000), implantation (22.0% versus 24.0%; p = 0.254) and multiple pregnancy rate (5.30% versus 7.20%; p = 0.394) were comparable among the two groups. Serum progesterone levels were significantly lower among the patients receiving dydrogesterone than the control group (13.62 ± 13.83 ng/ml versus 20.66 ± 18.09 ng/ml; p = 0.001). However, there was no statistically significant difference regarding the patients' satisfaction (p = 0.825) and tolerability (0.790) between the two groups. Our results showed that oral dydrogesterone (40 mg/day) is as effective as vaginal micronized progesterone considering its clinical outcomes and patients' satisfaction and tolerability, for LPS among women undergoing IVF.

    Full Text Available Multipotent stromal cells can be isolated from a variety of different tissues in the body. In contrast to stromal cells from the adult bone marrow (BM or adipose tissue, cord blood (CB multipotent stromal cells (MSC are biologically younger. Since first being described by our group, delta like 1 homologue (DLK-1 was determined as a discriminating factor between the distinct cord blood-derived subpopulations: the unrestricted somatic stromal cells (USSC, which lack adipogenic differentiation capacity, and the BM MSC-like CB MSC. In this study, experiments assessing the haematopoiesis-supporting capacity and molecular biological analyses were conducted and clearly confirmed different properties. Compared to CB MSC, USSC lead to a higher expansion of haematopoietic cells and in addition express significantly higher levels of insulin-like growth factor binding protein 1 (IGFBP1, but lower levels of IGF2. The data presented here also indicate that DLK-1 might not be the sole factor responsible for the inhibition of adipogenic differentiation potential in USSC but nevertheless indicates a biological diversity among cord blood-derived stromal cells.

    The quantitative assessment of image quality is an important consideration in any type of imaging system. The modulation transfer function (MTF) is a graphical description of the sharpness and contrast of an imaging system or of its individual components. The MTF is also known and spatial frequency response. The MTF curve has different meanings according to the corresponding frequency. The MTF of an optical system specifies the contrast transmitted by the system as a function of image size, and is determined by the inherent optical properties of the system. In this study, the polynomial and radial basis function (RBF) are applied as the kernel function of Support Vector Regression (SVR) to estimate and predict estimate MTF value of the actual optical system according to experimental tests. Instead of minimizing the observed training error, SVR_poly and SVR_rbf attempt to minimize the generalization error bound so as to achieve generalized performance. The experimental results show that an improvement in predictive accuracy and capability of generalization can be achieved by the SVR_rbf approach in compare to SVR_poly soft computing methodology.

    2010-12-01

    Full Text Available Abstract Background Experimentally validated data on gene regulation are hard to obtain. In particular, information about transcription factor binding sites in regulatory regions are scattered around in the literature. This impedes their systematic in-context analysis, e.g. the inference of their conservation in evolutionary history. Results We demonstrate the power of integrative bioinformatics by including curated transcription factor binding site information into the UCSC genome browser, using wiki and custom tracks, which enable easy publication of annotation data. Data integration allows to investigate the evolution of gene regulation of the pluripotency-associated genes Oct4, Sox2 and Nanog. For the first time, experimentally validated transcription factor binding sites in the regulatory regions of all three genes were assembled together based on manual curation of data from 39 publications. Using the UCSC genome browser, these data were then visualized in the context of multi-species conservation based on genomic alignment. We confirm previous hypotheses regarding the evolutionary age of specific regulatory patterns, establishing their "deep homology". We also confirm some other principles of Carroll's "Genetic theory of Morphological Evolution", such as "mosaic pleiotropy", exemplified by the dual role of Sox2 reflected in its regulatory region. Conclusions We were able to elucidate some aspects of the evolution of gene regulation for three genes associated with pluripotency. Based on the expected return on investment for the community, we encourage other scientists to contribute experimental data on gene regulation (original work as well as data collected for reviews to the UCSC system, to enable studies of the evolution of gene regulation on a large scale, and to report their findings.

    Aim: Psychological distress is common among patients affected by cancer. In this study, we examined the relationship between resilience, social support, and hopelessness among cancer patients treated with curative and palliative care. Patients and Methods: Sixty cancer patients in the age range of 18–65 years were randomly selected and divided into two groups based on their treatment intent namely, curative care (n = 30) and palliative care (n = 30). Both groups were assessed by the following instruments: Bharathiar University Resilience Scale, Multidimensional Scale of Perceived Social Support and Beck Hopelessness Scale. Results: Resilience was significantly associated with less hopelessness and higher levels of perceived social support. Conclusion: Cancer patients are found to be resilient, and the role of social support and hopelessness on promoting resilience cannot be ignored.

    2010-12-01

    This article analyses the benefits and shortcomings of the recently developed decision support systems (DSS) FLUMAGIS, Elbe-DSS, CatchMODS, and MedAction. The analysis elaborates on the following aspects: (i) application area/decision problem, (ii) stakeholder interaction/users involved, (iii) structure of DSS/model structure, (iv) usage of the DSS, and finally (v) most important shortcomings. On the basis of this analysis, we formulate four criteria that we consider essential for the successful use of DSS in landscape and river basin management. The criteria relate to (i) system quality, (ii) user support and user training, (iii) perceived usefulness and (iv) user satisfaction. We can show that the availability of tools and technologies for DSS in landscape and river basin management is good to excellent. However, our investigations indicate that several problems have to be tackled. First of all, data availability and homogenisation, uncertainty analysis and uncertainty propagation and problems with model integration require further attention. Furthermore, the appropriate and methodological stakeholder interaction and the definition of `what end-users really need and want' have been documented as general shortcomings of all four examples of DSS. Thus, we propose an iterative development process that enables social learning of the different groups involved in the development process, because it is easier to design a DSS for a group of stakeholders who actively participate in an iterative process. We also identify two important lines of further development in DSS: the use of interactive visualization tools and the methodology of optimization to inform scenario elaboration and evaluate trade-offs among environmental measures and management alternatives.

  9. Trajectory Browser: An online tool for interplanetary trajectory analysis and visualization

    Science.gov (United States)

    Foster, C.

    The Trajectory Browser is a web-based tool developed at the NASA Ames Research Center for finding preliminary trajectories to planetary bodies and for providing relevant launch date, time-of-flight and Δ V requirements. The site hosts a database of transfer trajectories from Earth to planets and small-bodies for various types of missions such as rendezvous, sample return or flybys. A search engine allows the user to find trajectories meeting desired constraints on the launch window, mission duration and Δ V capability, while a trajectory viewer tool allows the visualization of the heliocentric trajectory and the detailed mission itinerary. The anticipated user base of this tool consists primarily of scientists and engineers designing interplanetary missions in the context of pre-phase A studies, particularly for performing accessibility surveys to large populations of small-bodies. The educational potential of the website is also recognized for academia and the public with regards to trajectory design, a field that has generally been poorly understood by the public. The website is currently hosted on NASA-internal URL http://trajbrowser.arc.nasa.gov/ with plans for a public release in early 2013.

    Full Text Available Evolution of cloud makes users to manage the data and applications online. It is the responsibility of the cloud service providers to care of data secure in terms of transferring and efficient byproviding reliable performance. There are many challenges that are faced by the service providers to achieve the trust of the user. User feels insecure while the data is send to the cloud servers, when the data is more confident and uses applications that provide security to the data (by encryption and decryption. These applications to encrypt data will consume more time and systems resources. All these applications work depending upon the operating system of the user. This proposed approach will reduce user’s burden in interacting to the cloud through browsers add-on. This add-on is designed by AES encryption methodology with a SHA-2 key which is proved to be secure. The main aim of this paper is to explore various environments and design cloud based applications which are more user friendly at the same time reduce hardware cost. This design also highlights a threat to the mailing servers as they can’t find the transmitting information from the user.

    Weertman, B. R.

    2007-12-01

    We present a new generation of web based earthquake query tool - the IRIS Earthquake Browser (IEB). The IEB combines the DMC's large set of earthquake catalogs (provided by USGS/NEIC, ISC and the ANF) with the popular Google Maps web interface. With the IEB you can quickly and easily find earthquakes in any region of the globe. Using Google's detailed satellite images, earthquakes can be easily co-located with natural geographic features such as volcanoes as well as man made features such as commercial mines. A set of controls allow earthquakes to be filtered by time, magnitude, and depth range as well as catalog name, contributor name and magnitude type. Displayed events can be easily exported in NetCDF format into the GEON Integrated Data Viewer (IDV) where hypocenters may be visualized in three dimensions. Looking "under the hood", the IEB is based on AJAX technology and utilizes REST style web services hosted at the IRIS DMC. The IEB is part of a broader effort at the DMC aimed at making our data holdings available via web services. The IEB is useful both educationally and as a research tool.

  13. OpenMeetings as a browser-based teleconferencing tool for EFDA laboratories

    International Nuclear Information System (INIS)

    Remote participation is a key success factor for worldwide organizations and video-conference is an important aspect when laboratory collaborators are geographically dispersed. Several tools for video-conference are available worldwide. However, there is a need for a default integrated set of tools which provide all the needed features for remote participation between cooperating laboratories. Moreover, laboratories currently use different video-conference tools to communicate leading to a non-compatible method among them. OpenMeetings is open source software which provides video-conferences through web-browsing. It is operating system independent, requires no computer installation providing easy integration with already existing tools and customization of requirements. This paper intends to give an OpenMeetings overview as a video-conference application between worldwide laboratories and to demonstrate its integration with the European Fusion Development Agreement (EFDA) Federation authentication and authorization features. EFDA Federation is a multi-organization security infrastructure, whose purpose is to provide sharing and provision of a wide set of resources so that authenticated users may access them in a transparent and secure mode. This infrastructure is based on a distributed security technology called PAPI (Point of Access to Providers of Information). OpenMeetings can be a valuable EFDA Federation resource and a good approach as a method to provide a worldwide laboratory video-conferencing application, based on standard browsers.

    2016-01-01

    Summary: One gene can produce multiple transcript variants encoding proteins with different functions. To facilitate visual analysis of transcript variants, we developed ProtAnnot, which shows protein annotations in the context of genomic sequence. ProtAnnot searches InterPro and displays profile matches (protein annotations) alongside gene models, exposing how alternative promoters, splicing and 3′ end processing add, remove, or remodel functional motifs. To draw attention to these effects, ProtAnnot color-codes exons by frame and displays a cityscape graphic summarizing exonic sequence at each position. These techniques make visual analysis of alternative transcripts faster and more convenient for biologists. Availability and implementation: ProtAnnot is a plug-in App for Integrated Genome Browser, an open source desktop genome browser available from http://www.bioviz.org.

  18. From SuperClusters to Browsers: Using Research Simulations in Informal Education

    Science.gov (United States)

    Harold, J.; Dusenbery, P. B.

    2001-12-01

    As research fields push forward, continually creating more sophisticated and computationally intensive simulations, it can be forgotten that older modeling approaches can play a valuable role in educating the public. The bleeding edge simulation of a decade ago that ran only on supercomputers can now run from a browser window, giving non-scientists insights into physical systems as well as insights into how science is done. This translation from research to education is not always practical: many approaches are too abstract or not sufficiently "bullet proof" to be used in this way. But at their best, simulations can help create inquiry-based environments that allow the public to "do science" without needing to mastering the underlying mathematics. This approach is illustrated by a project funded by a small grant from NSF ISE through a program that provides education supplements to existing research awards. The project is a cooperative one that includes research scientists as well as professional educators. Using techniques adapted from a magnetospheric research program, applets are being built that allow web site visitors to explore the motion of particles in the Earth's magnetosphere. In order to maximize the impact of the program, the web pages will be linked to the Space Science Institute's Space Weather Center, a larger Space Weather outreach program that can provide background and context for the simulations. The scientists provide the technical expertise to re-implement the simulation in Java, so that it can be run over the web. The educators provide insight into how to identify specific learning goals, and how to accomplish those goals in an inquiry-based way using the web. We will describe some of the learning goals for the applets, as well as the approximations and compromises that need to be made to balance simulation accuracy with general public accessibility.

  19. Socializing Young People to Ethics via Play Experience: Browser Games and Parental Concerns for Safety Online

    Directory of Open Access Journals (Sweden)

    Divina Meigs

    2009-01-01

    Full Text Available This paper considers an online game and its relation to safety and privacy, in order to examine social and ethical issues raised by parental concern over harmful content. To gain real insights on the responsibility of adults, it develops a hands-on approach that takes into account the major stakeholders, especially young people and the related circle of people around them. Therefore the research question that is raised is: how do browser games provide reassurance to parents about their children’s safety and privacy? The issue of safety online is explored in three parts, using an ethnographic research framework: it explores a specific online game, it provides a profile of participants, it analyses their types of actions in relation to safety and privacy, and discusses the results in terms of incidence of risk, peer-monitoring and community control. The findings show that there is a rather strong tendency to self-regulation, but that tendency is partly due to a strong presence of mediating adults and peers. The results are discussed in terms of incidence of risk, peer-monitoring and networked means of control on the one hand, and in terms of scientific contribution to socialization theory on the other hand. They lead to final considerations on the repertoire of ethical strategies set up online and its meaning for the concerns of adults towards online risk as well as the need for policies on regulation and self-regulation. They also lead to extensions on the socialization to norms and the appropriation of ethics by young people.

    Wilkinson Mark

    2006-10-01

    Full Text Available Abstract Background The BioMoby project aims to identify and deploy standards and conventions that aid in the discovery, execution, and pipelining of distributed bioinformatics Web Services. As of August, 2006, approximately 680 bioinformatics resources were available through the BioMoby interoperability platform. There are a variety of clients that can interact with BioMoby-style services. Here we describe a Web-based browser-style client – Gbrowse Moby – that allows users to discover and "surf" from one bioinformatics service to the next using a semantically-aided browsing interface. Results Gbrowse Moby is a low-throughput, exploratory tool specifically aimed at non-informaticians. It provides a straightforward, minimal interface that enables a researcher to query the BioMoby Central web service registry for data retrieval or analytical tools of interest, and then select and execute their chosen tool with a single mouse-click. The data is preserved at each step, thus allowing the researcher to manually "click" the data from one service to the next, with the Gbrowse Moby application managing all data formatting and interface interpretation on their behalf. The path of manual exploration is preserved and can be downloaded for import into automated, high-throughput tools such as Taverna. Gbrowse Moby also includes a robust data rendering system to ensure that all new data-types that appear in the BioMoby registry can be properly displayed in the Web interface. Conclusion Gbrowse Moby is a robust, yet facile entry point for both newcomers to the BioMoby interoperability project who wish to manually explore what is known about their data of interest, as well as experienced users who wish to observe the functionality of their analytical workflows prior to running them in a high-throughput environment.

    Cheng, Andrew Y.; Li, Robert K.

    1992-03-01

    The method of finite element analysis is used to study some candidate composite materials: carbon filter reinforced epoxy and glass fiber reinforced epoxy. These composites may have real applications in the design of the optical support structures of very large telescopes where stringent thermomechanical stability are needed. The lightweight property of these materials allows one to build very stiff members for the optical support to withstand the structural deflections due to wind, vibration, and gravity. We have run finite element models of these composites using ABAQUS on a VAX VMS computer. Simple beams with rectangular cross- sections were computed for the composites with structural steel as a comparison. The static properties of these beams were studied.

  6. Evaluation of outputs from a 'Sustainable Nutrient Management Decision Support System' (SNM-DSS) compared to farmer opinion

    Science.gov (United States)

    2012-04-01

    Eutrophication of both fresh and coastal water bodies is one of the greatest threats to water quality in Europe and other developed countries. Sources of pollution are multiple but agriculture is known to be a large contributor, due to farm nutrient management such as land spreading of fertilisers and their subsequent loss via overland flow to surface waters. The stringent targets set for compliance with the Water Framework Directive by 2015 have led to action by the Irish regulatory authorities to reduce risk and prevent further deterioration of water status. One step was to prohibit the spreading of fertilisers over the winter period, with closed periods in 3 zones based on annual rainfall statistics. While this calendar approach is supported by scientific evidence, its justification has been debated by the farming community. A consequence of the regulation has been the concentration of hazard on dates directly preceding and following the closed period when soils can be heavily loaded with organic slurries and manures. An alternative lies in a Sustainable Nutrient Management Decision Support System (SNM-DSS), which has been developed to predict optimum conditions for fertiliser application depending on real-time observations of soil and weather conditions. The Hybrid Soil Moisture Deficit (HSMD) model forms the basis of this system and is essential for defining the thresholds for optimum management. The model outputs were tested against field water content data (θ) and evaluated by comparison with farmer opinion over a 3-year period. Daily Soil Moisture Deficit (SMD) was calculated from weather data collected on 5 sites and θ was estimated using time domain Reflectometry probes on 10 fields (2 × 5 sites). The question "Can slurry be spread today?" was also answered on a daily basis by 6 farmers located at the instrumented sites and the responses were related to calculated SMD values. A significant relationship between SMD and θ for all test sites showed that

    2007-09-01

    Captive giraffe (Giraffa camelopardalis) mostly do not attain the longevity possible for this species and frequently have problems associated with low energy intake and fat storage mobilization. Abnormal tooth wear has been among the causes suggested as an underlying problem. This study utilizes a tooth wear scoring method ("mesowear") primarily used in paleobiology. This scoring method was applied to museum specimens of free-ranging (n=20) and captive (n=41) giraffes. The scoring system allows for the differentiation between attrition--(typical for browsers, as browse contains little abrasive silica) and abrasion--(typical for grazers, as grass contains abrasive silica) dominated tooth wear. The dental wear pattern of the free-ranging population is dominated by attrition, resembles that previously published for free-ranging giraffe, and clusters within browsing herbivores in comparative analysis. In contrast, the wear pattern of the captive population is dominated by abrasion and clusters among grazing herbivores in comparative analyses. A potential explanation for this difference in tooth wear is likely related to the content of abrasive elements in zoo diets. Silica content (measured as acid insoluble ash) is low in browse and alfalfa. However, grass hay and the majority of pelleted compound feeds contain higher amounts of silica. It can be speculated that the abnormal wear pattern in captivity compromises tooth function in captive giraffe, with deleterious long-term consequences. PMID:17939353

    Full Text Available Abstract Background Deciphering gene regulatory networks by in silico approaches is a crucial step in the study of the molecular perturbations that occur in diseases. The development of regulatory maps is a tedious process requiring the comprehensive integration of various evidences scattered over biological databases. Thus, the research community would greatly benefit from having a unified database storing known and predicted molecular interactions. Furthermore, given the intrinsic complexity of the data, the development of new tools offering integrated and meaningful visualizations of molecular interactions is necessary to help users drawing new hypotheses without being overwhelmed by the density of the subsequent graph. Results We extend the previously developed TranscriptomeBrowser database with a set of tables containing 1,594,978 human and mouse molecular interactions. The database includes: (i predicted regulatory interactions (computed by scanning vertebrate alignments with a set of 1,213 position weight matrices, (ii potential regulatory interactions inferred from systematic analysis of ChIP-seq experiments, (iii regulatory interactions curated from the literature, (iv predicted post-transcriptional regulation by micro-RNA, (v protein kinase-substrate interactions and (vi physical protein-protein interactions. In order to easily retrieve and efficiently analyze these interactions, we developed In-teractomeBrowser, a graph-based knowledge browser that comes as a plug-in for Transcriptome-Browser. The first objective of InteractomeBrowser is to provide a user-friendly tool to get new insight into any gene list by providing a context-specific display of putative regulatory and physical interactions. To achieve this, InteractomeBrowser relies on a "cell compartments-based layout" that makes use of a subset of the Gene Ontology to map gene products onto relevant cell compartments. This layout is particularly powerful for visual integration

  11. A Phylogenetic Comparative Study of Bantu Kinship Terminology Finds Limited Support for Its Co-Evolution with Social Organisation.

    Directory of Open Access Journals (Sweden)

    Myrtille Guillon

    Full Text Available The classification of kin into structured groups is a diverse phenomenon which is ubiquitous in human culture. For populations which are organized into large agropastoral groupings of sedentary residence but not governed within the context of a centralised state, such as our study sample of 83 historical Bantu-speaking groups of sub-Saharan Africa, cultural kinship norms guide all aspects of everyday life and social organization. Such rules operate in part through the use of differing terminological referential systems of familial organization. Although the cross-cultural study of kinship terminology was foundational in Anthropology, few modern studies have made use of statistical advances to further our sparse understanding of the structuring and diversification of terminological systems of kinship over time. In this study we use Bayesian Markov Chain Monte Carlo methods of phylogenetic comparison to investigate the evolution of Bantu kinship terminology and reconstruct the ancestral state and diversification of cousin terminology in this family of sub-Saharan ethnolinguistic groups. Using a phylogenetic tree of Bantu languages, we then test the prominent hypothesis that structured variation in systems of cousin terminology has co-evolved alongside adaptive change in patterns of descent organization, as well as rules of residence. We find limited support for this hypothesis, and argue that the shaping of systems of kinship terminology is a multifactorial process, concluding with possible avenues of future research.

    Here, we present the data from a comparative physiology and proteomics approach used to analyze the response of two wheat genotypes (SERI M 82 (SE) and SW89.5193/kAu2 (SW)) with contrasting responses to drought stress. Proteomic analysis resulted in identification of 49 unique proteins with significant change in abundance (2-fold) under water shortage in roots and leaves. Gene ontology analysis of drought-responsive proteins (DRPs) suggested an induction of proteins related to cell wall biogenesis, ATP synthesis, photosynthesis, and carbohydrate/energy metabolism in leaves under stress condition. A large fraction of root proteins were identified to be involved in defense and oxidative stress response. In addition, a significant change was detected in proteins related to protein synthesis, ATP synthesis, and germin-like proteins in response to drought stress. A detailed analysis of this data may be obtained from Ref. [1]. PMID:26217700

    Full Text Available Here we provide the LC–MS/MS data from a comparative analysis of Listeria monocytogenes ATCC 7644 treated and non-treated with a sublethal concentration of nisin (10−3 mg/mL. Protein samples were analyzed by multidimensional protein identification technology (MudPIT approach, in an off-line configuration. The raw MS/MS data allowed the detection of 49,591 spectra which resulted in 576 protein identifications. After Scaffold validation, 179 proteins were identified with high confidence. A label-free quantitative analysis based of normalized spectral abundance factor (NSAF was used and 13 proteins were found differentially expressed between nisin-treated and non-treated cells. Gene ontology analysis of differentially expressed proteins revealed that most of them are correlated to metabolic process, oxidative stress response mechanisms and molecular binding. A detailed analysis and discussion of these data may be found in Miyamoto et al. [1].

  14. Comparative analysis of instance selection algorithms for instance-based classifiers in the context of medical decision support

    International Nuclear Information System (INIS)

    When constructing a pattern classifier, it is important to make best use of the instances (a.k.a. cases, examples, patterns or prototypes) available for its development. In this paper we present an extensive comparative analysis of algorithms that, given a pool of previously acquired instances, attempt to select those that will be the most effective to construct an instance-based classifier in terms of classification performance, time efficiency and storage requirements. We evaluate seven previously proposed instance selection algorithms and compare their performance to simple random selection of instances. We perform the evaluation using k-nearest neighbor classifier and three classification problems: one with simulated Gaussian data and two based on clinical databases for breast cancer detection and diagnosis, respectively. Finally, we evaluate the impact of the number of instances available for selection on the performance of the selection algorithms and conduct initial analysis of the selected instances. The experiments show that for all investigated classification problems, it was possible to reduce the size of the original development dataset to less than 3% of its initial size while maintaining or improving the classification performance. Random mutation hill climbing emerges as the superior selection algorithm. Furthermore, we show that some previously proposed algorithms perform worse than random selection. Regarding the impact of the number of instances available for the classifier development on the performance of the selection algorithms, we confirm that the selection algorithms are generally more effective as the pool of available instances increases. In conclusion, instance selection is generally beneficial for instance-based classifiers as it can improve their performance, reduce their storage requirements and improve their response time. However, choosing the right selection algorithm is crucial.

    Full Text Available Objectives: While mindfulness-based interventions have received widespread application in both clinical and non-clinical populations, the mechanism by which mindfulness meditation improves well-being remains elusive. One possibility is that mindfulness training alters the processing of emotional information, similar to prevailing cognitive models of depression and anxiety. The aim of this study was to investigating the effects of mindfulness training on emotional information processing (i.e. memory biases in relation to both clinical symptomatology and well-being in comparison to active control conditions.Methods: Fifty-eight university students (28 female, age = 20.1 ± 2.7 years participated in either a 12-week course containing a "meditation laboratory" or an active control course with similar content or experiential practice laboratory format (music. Participants completed an emotional word recall task and self-report questionnaires of well-being and clinical symptoms before and after the 12-week course.Results: Meditators showed greater increases in positive word recall compared to controls F(1, 56 = 6.6, p = .02. The meditation group increased significantly more on measures of well-being [F(1, 56 = 6.6, p = .01], with a marginal decrease in depression and anxiety [(F(1, 56 = 3.0, p = .09] compared to controls. Increased positive word recall was associated with increased psychological well-being [r = 0.31, p = .02] and decreased clinical symptoms [r = -0.29, p = .03].Conclusion: Mindfulness training was associated with greater improvements in processing efficiency for positively valenced stimuli than active control conditions. This change in emotional information processing was associated with improvements in psychological well-being and less depression and anxiety. These data suggest that mindfulness training may improve well-being via changes in emotional information processing.

    Panic disorder (PD) is one of the most common psychiatric disorders. Web-based self-help treatments for PD have had promising results. These online treatments seem to have larger effect sizes (ESs) when professional support is added. However, the amount of support or how it should be administered is not yet clear. The aim of this trial was to study two ways of administering psychological support provided by phone as a part of Internet-based self-help treatment for PD based on cognitive behavioral therapy. Seventy-seven participants diagnosed with PD were randomly assigned to one of three experimental conditions: a waiting list control group; a treatment group with non-scheduled psychological support; or a treatment group with scheduled psychological support. PD symptoms of participants who received treatment improved significantly compared to the control group (mean ES d = 1.18, p < .05). In addition, there were statistically and clinically significant differences between treatment groups (Mean difference = -3.20, p = .005, 95% CI [-5.62, -.79]). The scheduled group showed a larger ES, a lower dropout rate, and better adherence to treatment than the non-scheduled group. Scheduled support seems to be indicated for patients who seek Web-based treatment for PD, and their symptoms of panic, anxiety, and depression improve at post-treatment and six-month follow-up. In contrast, when support depends on patient demand, they receive less support and so, the therapeutic effect is poorer. PMID:27007256

    2013-06-01

    Full Text Available Aim of present study is to evaluate the effect of salinity on the growth of Rhizobium symbiosis with various cultivars of Berseem (WARDAN, BB3, JHB 052 and BB2. Two sets of plots were maintained in which one set contained non-inoculated while another set contained inoculated seeds with Rhizobium culture, which were irrigated with saline waters of different concentrations (0, 3, 6, 7.2, 10, 12 and 14 dSm-1. The observations have been recorded only at 90 and 120 DAS but nodular leghaemoglobin had been estimated at 90th day stage. Results indicated that nodulation and lb content had been increased generally upto 7.2 dSm-1 and declined thereafter. Inoculation with Rhizobium culture had invariably and significantly promoted nodulation and lb content at both durations particularly at lower EC levels and minimized the deleterious effect of salinity at 10 to 14 dSm-1. Taken together, our findings indicate that cv. BB3 produced maximum nodulation and lb content almost at all saline irrigations but cv. WARDAN registered beneficial effect of Rhizobium culture inoculation as this cultivar registered greater lb content at 3 to 7.2 dSm-1 and lesser reductions at 10 to 14 dSm-1 when compared with uninoculated sets. We concluded that this experiment reveals the great impact of Rhizobium trifolii culture on berseem cultivars along with the use of saline soil and water for agriculture without using fertile land and normal water, hence there will be a substantial conservation of normal water and soil for further use.

  20. Comet-toolbox: Numerical simulations of cometary dust tails in your browser

    Vincent, J.

    2014-07-01

    The last few years have seen a rise in the popularity of comets, on both professional and amateur levels. Many cometary events, sometimes visible without a telescope, have triggered worldwide campaigns of ground- and space-based observations: for instance, the explosion of comet 17P/Holmes, the sungrazers C/2006 P1 (McNaught) and C/2012 S1 (ISON), or the forthcoming close encounter of C/2013 A1 (Siding Springs) and Mars. With the overwhelming amount of data available, it becomes more and more important to release the models we use to analyze these events. This ensures not only that more people get the opportunity to investigate the data, but is also beneficial for the science itself as everybody is able to see, use, and improve the models. As a professional planetary scientist, I have written many tools to process the data I use, especially in the field of cometary and asteroid science [1-6]. With the progress of modern computers, it is now possible to translate these tools to simple HTML/Javascript interfaces and run the models in an Internet browser. I have decided to make my tools available in this way, to be used by anybody interested in modeling cometary processes. The first tool being released at ACM 2014 is the Finson-Probstein diagram. The motion of dust particles in a cometary environment is a complex process. A precise description of the grain trajectories requires advanced hydrodynamic models. In the tail, dust and gas are decoupled and the only significant forces affecting the grain trajectories are the solar gravity and radiation pressure. Both forces depend on the square of the heliocentric distance but work in opposite directions. Their sum can be seen as a reduced solar gravity, and the equation of motion is simply m × a = (1-β) × Sun_{gravity}, where β is the ratio P_{radiation}/Sun_{gravity}, and is inversely proportional to the size of the grains for particles larger than 1 micron. From this relation, Finson & Probstein (1968, [7]) proposed a

  1. How robust is a robust policy? A comparative analysis of alternative robustness metrics for supporting robust decision analysis.

    In response to climate and socio-economic change, in various policy domains there is increasingly a call for robust plans or policies. That is, plans or policies that performs well in a very large range of plausible futures. In the literature, a wide range of alternative robustness metrics can be found. The relative merit of these alternative conceptualizations of robustness has, however, received less attention. Evidently, different robustness metrics can result in different plans or policies being adopted. This paper investigates the consequences of several robustness metrics on decision making, illustrated here by the design of a flood risk management plan. A fictitious case, inspired by a river reach in the Netherlands is used. The performance of this system in terms of casualties, damages, and costs for flood and damage mitigation actions is explored using a time horizon of 100 years, and accounting for uncertainties pertaining to climate change and land use change. A set of candidate policy options is specified up front. This set of options includes dike raising, dike strengthening, creating more space for the river, and flood proof building and evacuation options. The overarching aim is to design an effective flood risk mitigation strategy that is designed from the outset to be adapted over time in response to how the future actually unfolds. To this end, the plan will be based on the dynamic adaptive policy pathway approach (Haasnoot, Kwakkel et al. 2013) being used in the Dutch Delta Program. The policy problem is formulated as a multi-objective robust optimization problem (Kwakkel, Haasnoot et al. 2014). We solve the multi-objective robust optimization problem using several alternative robustness metrics, including both satisficing robustness metrics and regret based robustness metrics. Satisficing robustness metrics focus on the performance of candidate plans across a large ensemble of plausible futures. Regret based robustness metrics compare the

    2008-07-01

    Full Text Available The study compared the support and rewards provided faculty members for online course teaching and the development approaches used at business schools accredited by AACSB between 2001 and 2006. Data were collected from 81 professors in 2001 and 140 professors in 2006. The professors were involved in developing or teaching online courses at AACSB business schools across the United States. The findings indicate that faculty members received limited support and are not taking advantage of training options. Faculty members are most likely rewarded for their involvement in distance learning through stipends based on the number of online sections taught. Little has changed during the five-year period in regards to course development. Faculty members continue to use an individual instead of a team approach to course development and most faculty members learned online course development and delivery techniques on their own.

  3. A database and tool, IM Browser, for exploring and integrating emerging gene and protein interaction data for Drosophila

    2006-04-01

    Full Text Available Abstract Background Biological processes are mediated by networks of interacting genes and proteins. Efforts to map and understand these networks are resulting in the proliferation of interaction data derived from both experimental and computational techniques for a number of organisms. The volume of this data combined with the variety of specific forms it can take has created a need for comprehensive databases that include all of the available data sets, and for exploration tools to facilitate data integration and analysis. One powerful paradigm for the navigation and analysis of interaction data is an interaction graph or map that represents proteins or genes as nodes linked by interactions. Several programs have been developed for graphical representation and analysis of interaction data, yet there remains a need for alternative programs that can provide casual users with rapid easy access to many existing and emerging data sets. Description Here we describe a comprehensive database of Drosophila gene and protein interactions collected from a variety of sources, including low and high throughput screens, genetic interactions, and computational predictions. We also present a program for exploring multiple interaction data sets and for combining data from different sources. The program, referred to as the Interaction Map (IM Browser, is a web-based application for searching and visualizing interaction data stored in a relational database system. Use of the application requires no downloads and minimal user configuration or training, thereby enabling rapid initial access to interaction data. IM Browser was designed to readily accommodate and integrate new types of interaction data as it becomes available. Moreover, all information associated with interaction measurements or predictions and the genes or proteins involved are accessible to the user. This allows combined searches and analyses based on either common or technique-specific attributes

    The Current Comparative Table (CCT) software program enables working biologists to automate customized bioinformatics searches, typically of remote sequence or HMM (hidden Markov model) databases. CCT currently supports BLAST, hmmpfam and other programs useful for gene and ortholog identification. The software is web based, has a BioPerl core and can be used remotely via a browser or locally on Mac OS X or Linux machines. CCT is particularly useful to scientists who study large sets of molecules in today's evolving information landscape because it color-codes all result files by age and highlights even tiny changes in sequence or annotation. By empowering non-bioinformaticians to automate custom searches and examine current results in context at a glance, CCT allows a remote database submission in the evening to influence the next morning's bench experiment. A demonstration of CCT is available at and the open source software is freely available from . PMID:15980582

  6. Prototype of Multifunctional Full-text Library in the Architecture Web-browser / Web-server / SQL-server

    Science.gov (United States)

    Lyapin, Sergey; Kukovyakin, Alexey

    Within the framework of the research program "Textaurus" an operational prototype of multifunctional library T-Libra v.4.1. has been created which makes it possible to carry out flexible parametrizable search within a full-text database. The information system is realized in the architecture Web-browser / Web-server / SQL-server. This allows to achieve an optimal combination of universality and efficiency of text processing, on the one hand, and convenience and minimization of expenses for an end user (due to applying of a standard Web-browser as a client application), on the other one. The following principles underlie the information system: a) multifunctionality, b) intelligence, c) multilingual primary texts and full-text searching, d) development of digital library (DL) by a user ("administrative client"), e) multi-platform working. A "library of concepts", i.e. a block of functional models of semantic (concept-oriented) searching, as well as a subsystem of parametrizable queries to a full-text database, which is closely connected with the "library", serve as a conceptual basis of multifunctionality and "intelligence" of the DL T-Libra v.4.1. An author's paragraph is a unit of full-text searching in the suggested technology. At that, the "logic" of an educational / scientific topic or a problem can be built in a multilevel flexible structure of a query and the "library of concepts", replenishable by the developers and experts. About 10 queries of various level of complexity and conceptuality are realized in the suggested version of the information system: from simple terminological searching (taking into account lexical and grammatical paradigms of Russian) to several kinds of explication of terminological fields and adjustable two-parameter thematic searching (a [set of terms] and a [distance between terms] within the limits of an author's paragraph are such parameters correspondingly).

    Full Text Available Personalised external aortic support was first proposed in 2000 by Tal Golesworthy, an engineer with familial Marfan syndrome and an aortic root aneurysm. After putting together a research and development team, and finding a surgeon to take on the challenge to join him in this innovative approach, he was central to the manufacture of the device, custom made for his own aorta. He was the patient for the ‘first in man’ operation in 2004. Ten years later he is well and 45 other people have had their own personalised device implanted. In this account, the stepwise record of proof of principle, comparative quantification of the surgical and perioperative requirements, 10 years of results, and development and research plans for the future are presented.

  8. A comparative study of silver-graphene oxide nanocomposites as a recyclable catalyst for the aerobic oxidation of benzyl alcohol: Support effect

    International Nuclear Information System (INIS)

    Graphical abstract: - Highlights: • Characteristics of three different graphene oxide (GO) are studied as a support for Ag nanoparticles. • The required conditions for a best support are determined. • For the first time the silver nanoparticles decorated GO as catalyst for aerobic oxidation of benzyl alcohol and the effects of the degree of reduction of GO on AgNPs on GO are reported. - Abstract: Three different nanocomposites of silver and graphene oxide, namely silver nanoparticles (AgNPs) immobilized on reduced graphene oxide (AgNPs/rGO), partially reduced graphene oxide (AgNPs/GO) and thiolated partially reduced graphene oxide (AgNPs/GOSH), were synthesized in order to compare their properties. Characterizations were carried out by infrared and UV–Vis and Raman spectroscopy, ICP, X-ray diffraction, SEM and TEM, confirming both the targeted chemical modification and the composite formation. The nanocomposites were successfully employed in the aerobic oxidation of benzyl alcohol at atmospheric pressure. AgNPs/GOSH is stable and recyclable catalyst which showed the highest activity in the aerobic oxidation of benzyl alcohol in the presence of N-hydroxyphthalimide (NHPI) to give benzaldehyde with 58% selectivity in 24 h at 61% conversion. The favorite properties of AgNPs/GOSH are reasonably attributed to the stable and well distributed AgNPs over GOSH due to strong adhesion between AgNPs and GOSH

    2011-08-01

    Full Text Available Abstract Background Effective treatment strategies for chronic depression are urgently needed since it is not only a common and particularly disabling disorder, but is also considered treatment resistant by most clinicians. There are only a few studies on chronic depression indicating that traditional psycho- and pharmacological interventions are not as effective as in acute, episodic depression. Current medications are no more effective than those introduced 50 years ago whereas the only psychotherapy developed specifically for the subgroup of chronic depression, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP, faired well in one large trial. However, CBASP has never been directly compared to a non-specific control treatment. Methods/Design The present article describes the study protocol of a multisite parallel-group randomized controlled trial in Germany. The purpose of the study is to estimate the efficacy of CBASP compared to supportive psychotherapy in 268 non-medicated early-onset chronically depressed outpatients. The intervention includes 20 weeks of acute treatment with 24 individual sessions followed by 28 weeks of continuation treatment with another 8 sessions. Depressive symptoms are evaluated 20 weeks after randomisation by means of the 24-item Hamilton Rating Scale of Depression (HRSD. Secondary endpoints are depressive symptoms after 12 and 48 weeks, and remission after 12, 20, and 48 weeks. Primary outcome will be analysed using analysis of covariance (ANCOVA controlled for pre-treatment scores and site. Analyses of continuous secondary variables will be performed using linear mixed models. For remission rates, chi-squared tests and logistic regression will be applied. Discussion The study evaluates the comparative effects of a disorder-specific psychotherapy and a well designed non-specific psychological approach in the acute and continuation treatment phase in a large sample of early-onset chronically

    2003-08-01

    The Continuous Plankton Recorder (CPR) survey provides a unique multi-decadal dataset on the abundance of plankton in the North Sea and North Atlantic and is one of only a few monitoring programmes operating at a large spatio-temporal scale. The results of all samples analysed from the survey since 1946 are stored on an Access Database at the Sir Alister Hardy Foundation for Ocean Science (SAHFOS) in Plymouth. The database is large, containing more than two million records (~80 million data points, if zero results are added) for more than 450 taxonomic entities. An open data policy is operated by SAHFOS. However, the data are not on-line and so access by scientists and others wishing to use the results is not interactive. Requests for data are dealt with by the Database Manager. To facilitate access to the data from the North Sea, which is an area of high research interest, a selected set of data for key phytoplankton and zooplankton species has been processed in a form that makes them readily available on CD for research and other applications. A set of MATLAB tools has been developed to provide an interpolated spatio-temporal description of plankton sampled by the CPR in the North Sea, as well as easy and fast access to users in the form of a browser. Using geostatistical techniques, plankton abundance values have been interpolated on a regular grid covering the North Sea. The grid is established on centres of 1° longitude x 0.5° latitude (~32 × 30 nautical miles). Based on a monthly temporal resolution over a fifty-year period (1948-1997), 600 distribution maps have been produced for 54 zooplankton species, and 480 distribution maps for 57 phytoplankton species over the shorter period 1958-1997. The gridded database has been developed in a user-friendly form and incorporates, as a package on a CD, a set of options for visualisation and interpretation, including the facility to plot maps for selected species by month, year, groups of months or years, long

    Data from captive animals indicated that browsing (BR) ruminants have larger fecal particles-indicative of lesser chewing efficiency-than grazers (GR). To answer whether this reflects fundamental differences between the animal groups, or different reactions of basically similar organisms to diets fed in captivity, we compared mean fecal particle size (MPS) in a GR and a BR ruminant (aurox Bos primigenius taurus, giraffe Giraffa camelopardalis) and a GR and a BR hindgut fermenter (Przewalski's...

  15. Comparative study of supported CuOx and MnOx catalysts for the catalytic wet air oxidation of β-naphthol

    International Nuclear Information System (INIS)

    Highlights: ► Degradation of β-naphthol was carried out by CWAO and the COD removal was 93.7%. ► Comparative study of supported CuOx and MnOx catalysts was implemented. ► Destruction of β-naphthol was catalyzed by metal oxides supported on nano-TiO2. - Abstract: MnOx/nano-TiO2, MnOx/Al2O3–TiO2 (Al-Ti), CuOx/nano-TiO2 and CuOx/Al-Ti were prepared and their application in catalytic wet air oxidation (CWAO) of β-naphthol were investigated. The catalysts had been characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and temperature-programmed reduction (TPR) measurements. Phases of CuO, Cu2O, CuAl2O4, MnO2 and Mn2O3 could be found on the surface of the aforementioned catalysts. Significant differences in activities were observed among the prepared catalysts. Compared to CuOx/nano-TiO2, the combined action of highly dispersed CuO as well as CuAl2O4 of CuOx/Al-Ti helped to achieve higher activity for the CWAO of β-naphthol, while the Cu2O component lead to lower efficiency of CuOx/nano-TiO2. On the surface of MnOx/nano-TiO2, both the larger amount of highly dispersed MnO2 and the stronger electron transfer between MnO2 and Mn2O3 were helpful to promote the activity for the degradation of β-naphthol. However, the higher amount of bulk MnO2 and the weaker electron transfer for MnOx/Al-Ti were unfavorable to increase its efficiency. Among the four catalysts as-prepared, MnOx/nano-TiO2 was identified the highest activity with 93.7% COD removal.

    2015-09-01

    A comparative study was carried out on a small-pore CHA.Cu and a large-pore BEA.Cu zeolite catalyst to understand the lower N2O formation on small-pore zeolite supported Cu catalysts in the selective catalytic reduction (SCR) of NOx with NH3. On both catalysts, the N2O yield increases with an increase in the NO2/NOx ratios of the feed gas, suggesting N2O formation via the decomposition of NH4NO3. Temperature-programmed desorption experiments reveal that NH4NO3 is more stable on CHA.Cu than on BEA.Cu. In situ FTIR spectra following stepwise (NO2 + O2) and (15NO + NH3 + O2) adsorption and reaction, and product distribution analysis using isotope-labelled reactants, unambiguously prove that surface nitrate groups are essential for the formation of NH4NO3. Furthermore, CHA.Cu is shown to be considerably less active than BEA.Cu in catalyzing NO oxidation and the subsequent formation of surface nitrate groups. Both factors, i.e., (1) the higher thermal stability of NH4NO3 on CHA.Cu, and (2) the lower activity for this catalyst to catalyze NO oxidation and the subsequent formation of surface nitrates, likely contribute to the higher SCR selectivity with less N2O formation on this catalyst as compared to BEA.Cu. The latter is determined as the primary reason since surface nitrates are the source that leads to the formation of NH4NO3 on the catalysts.

  17. GrayStarServer: Server-side spectrum synthesis with a browser-based client-side user interface

    CERN Document Server

    Short, C Ian

    2016-01-01

    I present GrayStarServer (GSS), a stellar atmospheric modeling and spectrum synthesis code of pedagogical accuracy that is accessible in any web browser on commonplace computational devices and that runs on a time-scale of a few seconds. The addition of spectrum synthesis annotated with line identifications extends the functionality and pedagogical applicability of GSS beyond that of its predecessor, GrayStar3 (GS3). The spectrum synthesis is based on a line list acquired from the NIST atomic spectra database, and the GSS post-processing and user interface (UI) client allows the user to inspect the plain text ASCII version of the line list, as well as to apply macroscopic broadening. Unlike GS3, GSS carries out the physical modeling on the server side in Java, and communicates with the JavaScript and HTML client via an asynchronous HTTP request. I also describe other improvements beyond GS3 such as more realistic modeling physics and use of the HTML element for higher quality plotting and rendering of result...

    For the Library of Integrated Network-based Cellular Signatures (LINCS) project many gene expression signatures using the L1000 technology have been produced. The L1000 technology is a cost-effective method to profile gene expression in large scale. LINCS Canvas Browser (LCB) is an interactive HTML5 web-based software application that facilitates querying, browsing and interrogating many of the currently available LINCS L1000 data. LCB implements two compacted layered canvases, one to visualize clustered L1000 expression data, and the other to display enrichment analysis results using 30 different gene set libraries. Clicking on an experimental condition highlights gene-sets enriched for the differentially expressed genes from the selected experiment. A search interface allows users to input gene lists and query them against over 100 000 conditions to find the top matching experiments. The tool integrates many resources for an unprecedented potential for new discoveries in systems biology and systems pharmacology. The LCB application is available at http://www.maayanlab.net/LINCS/LCB. Customized versions will be made part of the http://lincscloud.org and http://lincs.hms.harvard.edu websites. PMID:24906883

  20. Nutritional support of bone marrow transplant recipients: a prospective, randomized clinical trial comparing total parental nutrition to an enteral feeding program

    International Nuclear Information System (INIS)

    Allogeneic and autologous bone marrow transplantation (BMT) have been associated with nutritionally-depleting side effects. Total parental nutrition (TPN) has become the standard, but it has not been demonstrated that TPN is the appropriate method of nutritional support. Therefore, in a prospective, randomized clinical trial TPN and enteral feeding were compared for their effectiveness in maintaining the nutritional status of patients through the first 29 post-transplant days. Nutritional assessment included measurement of serum proteins, body weight, anthropometry and isotope dilution analysis of body composition. Total body water (TBW) and extracellular fluid (ECF) were quantified by standard radioisotope dilution techniques using tritiated water and 169ytterbium-diethylenetriaminepentaacetate, respectively as the tracers. Consenting patients 10-58 years of age were stratified by type of BMT (autologous or allogeneic) and randomized to either TPN plus ad libitum oral feeding or the individualized enteral feeding program (EFP), which included one-on-one counseling, meal-by-meal menu selection, special snacks and tube feeding. There were no differences in the rate of hematologic recovery, incidence of graft-versus-host disease, organ toxicity, length of hospitalization or survival. Therefore, the observed changes in body composition were not clinically significant. Even allowing for increased dietary service, the EFP was only half as expensive as TPN. It was concluded that TPN is not superior to the EFP and therefore, TPN should be reserved for patients who demonstrate intolerance to enteral feeding

    Full Text Available This study compares first graders’ acquisition of literacy in two different instructional settings. One teacher used a traditional skill-based approach while the other one was identified as a whole language teacher using literature and writing experiences with incidental attention to phonics. During the school year, documentation collection about the pedagogy included questionnaires, field notes of monthly observations of reading and writing lessons, systematic collections of the activities, and analysis of the linguistic structures contained in the texts used for reading lessons in both classrooms. Data collection was conducted longitudinally and involved three tasks: invented spelling, oral reading and reading content recall. Various analyses indicate that both groups of children learnt the graphophonic system and were able to use it for encoding and decoding. Differences between the two groups were in the difficulties encountered in the three tasks. The influence of the way the teacher leads the reading lessons, the activities proposed and the reading supports used on first graders’ difficulties and the strategies used are discussed.

    The integration of a browser based operator manual in the system environment of a process computer system is an optimization of the operating procedure in the control room and a safety enhancement due to faster and error-free access to the manual contents. Several requirements by the authorities have to be fulfilled: the operating manual has to be available as hard copy, the format has to be true to original, protection against manipulation has to be provided, the manual content of the browser-based version and the hard copy have to identical, and the display presentation has to be consistent with ergonomic principals. The integration of the on-line manual in the surveillance process computer system provides the operator with the relevant comments to the surveillance signal. The described integration of the on-line manual is an optimization of the operator's everyday job with respect to ergonomics and safety (human performance).

    2012-01-01

    Full Text Available Abstract Background Originating from a marine ancestor, the myriapods most likely invaded land independently of the hexapods. As these two evolutionary lineages conquered land in parallel but separately, we are interested in comparing the myriapod chemosensory system to that of hexapods to gain insights into possible adaptations for olfaction in air. Our study connects to a previous analysis of the brain and behavior of the chilopod (centipede Scutigera coleoptrata in which we demonstrated that these animals do respond to volatile substances and analyzed the structure of their central olfactory pathway. Results Here, we examined the architecture of the deutocerebral brain areas (which process input from the antennae in seven additional representatives of the Chilopoda, covering all major subtaxa, by histology, confocal laser-scan microscopy, and 3D reconstruction. We found that in all species that we studied the majority of antennal afferents target two separate neuropils, the olfactory lobe (chemosensory, composed of glomerular neuropil compartments and the corpus lamellosum (mechanosensory. The numbers of olfactory glomeruli in the different chilopod taxa ranged from ca. 35 up to ca. 90 and the shape of the glomeruli ranged from spheroid across ovoid or drop-shape to elongate. Conclusion A split of the afferents from the (first pair of antennae into separate chemosensory and mechanosensory components is also typical for Crustacea and Hexapoda, but this set of characters is absent in Chelicerata. We suggest that this character set strongly supports the Mandibulata hypothesis (Myriapoda + (Crustacea + Hexapoda as opposed to the Myriochelata concept (Myriapoda + Chelicerata. The evolutionary implications of our findings, particularly the plasticity of glomerular shape, are discussed.

    The pace of scientific discovery is being transformed by the availability of 'big data' and open access, open source software tools. These innovations open up new avenues for how scientists communicate and share data and ideas with each other and with the general public. Here, we describe our efforts to bring to life our studies of the Earth system, both at present day and through deep geological time. The GPlates Portal (portal.gplates.org) is a gateway to a series of virtual globes based on the Cesium Javascript library. The portal allows fast interactive visualization of global geophysical and geological data sets, draped over digital terrain models. The globes use WebGL for hardware-accelerated graphics and are cross-platform and cross-browser compatible with complete camera control. The globes include a visualization of a high-resolution global digital elevation model and the vertical gradient of the global gravity field, highlighting small-scale seafloor fabric such as abyssal hills, fracture zones and seamounts in unprecedented detail. The portal also features globes portraying seafloor geology and a global data set of marine magnetic anomaly identifications. The portal is specifically designed to visualize models of the Earth through geological time. These space-time globes include tectonic reconstructions of the Earth's gravity and magnetic fields, and several models of long-wavelength surface dynamic topography through time, including the interactive plotting of vertical motion histories at selected locations. The globes put the on-the-fly visualization of massive data sets at the fingertips of end-users to stimulate teaching and learning and novel avenues of inquiry. PMID:26960151

    This study aimed at investigating the interaction of V2O5 species with TiO2 and Al2O3 supports to understand the effect of supports on SCR reaction. Analysis by XRD, BET, UV-vis, and DFT theoretical calculations, XPS, EPR and in situ DRIFT showed that the two kinds of supports could interact with V2O5. The interaction of electron excitation and charge transfer of supports to V2O5 species was important to the formation of the reduced V2O5. These aspects increased the formation of superoxide ions that could improve the NO oxidation over V2O5/TiO2. It was responsible for the higher SCR catalytic activity of V2O5/TiO2 than V2O5/Al2O3.

    International Nuclear Information System (INIS)

    Different support instruments for renewable energy expose investors differently to market risks. This has implications on the attractiveness of investment. We use mean–variance portfolio analysis to identify the risk implications of two support instruments: feed-in tariffs and feed-in premiums. Using cash flow analysis, Monte Carlo simulations and mean–variance analysis, we quantify risk-return relationships for an exemplary offshore wind park in a simplified setting. We show that feed-in tariffs systematically require lower direct support levels than feed-in premiums while providing the same attractiveness for investment, because they expose investors to less market risk. These risk implications should be considered when designing policy schemes. - Highlights: • Mean–variance portfolio approach to analyse risk implications of policy instruments. • We show that feed-in tariffs require lower support levels than feed-in premiums. • This systematic effect stems from the lower exposure of investors to market risk. • We created a stochastic model for an exemplary offshore wind park in West Denmark. • We quantify risk-return, Sharpe Ratios and differences in required support levels

  11. Comparative analysis of different supporting measures for the production of electrical energy by solar PV and Wind systems. Four representative European cases

    International Nuclear Information System (INIS)

    In the 9th of March 2007, the European Council decided a fixing goal of 20% contribution of the renewable energy sources (RES) on the total European electric energy production in 2020. In order to reach such an ambitious goal, all the European countries are adopting different support policies for encouraging the installations of RES-based generation systems. In this paper, after a brief review on the main support policies for RES in Europe, the specific situations of four representative countries (France, Germany, Italy and Spain) are examined, with the purpose of putting into evidence the main differences in the support policies adopted for Photovoltaic (PV) and Wind systems. In particular, a comparison based on the calculation of the pay-back-period (PBP), the net present value (NPV) and the internal rate of return (IRR), for different sized PV and Wind systems, shows that in some situations a support policy can be not convenient for the owner of the RES-based generation system and that, in many cases, the differences between the way of implementation of the same support policy in different countries, can give place to significantly different results.

    The effects of interactions of Pt nanoparticles with hybrid supports on reactivity towards ethanol oxidation in alkaline solution are investigated. Studies involve catalysts with identical Pt nanoparticles on six hybrid supports containing carbon powder and transition metal oxides (TiO2, ZrO2, SnO2, CeO2, MoO3 and WO3). In situ X-ray absorption spectroscopy (XAS) results evidence that metal-support interactions produce changes in the Pt 5d band vacancy, which appears to determine the catalytic activity. The highest and lowest activities are observed for Pt nanoparticles on hybrid supports containing TiO2 and CeO2, respectively. Further studies are presented for these two catalysts. In situ FTIR reflection spectroscopy measurements, taken using both multi-stepped FTIR spectroscopy (MS-FTIR) and single potential alteration FTIR spectroscopy (SPA-FTIR), evidence that the main product of ethanol oxidation is acetate, although signals attributed to carbonate and CO2 indicate some differences in CO2 production. Fuel cell performances of these catalysts, tested in a 4.5 cm2 single cell at different temperatures (40-90 °C) show good agreement with data obtained by electrochemical techniques. Results of this comprehensive study point out the possibility of compensating a reduction of noble metal load with an increase in activity promoted by interactions between metallic nanoparticles and a support.

  15. Comparative Genome Viewer

    International Nuclear Information System (INIS)

    The amount of information about genomes, both in the form of complete sequences and annotations, has been exponentially increasing in the last few years. As a result there is the need for tools providing a graphical representation of such information that should be comprehensive and intuitive. Visual representation is especially important in the comparative genomics field since it should provide a combined view of data belonging to different genomes. We believe that existing tools are limited in this respect as they focus on a single genome at a time (conservation histograms) or compress alignment representation to a single dimension. We have therefore developed a web-based tool called Comparative Genome Viewer (Cgv): it integrates a bidimensional representation of alignments between two regions, both at small and big scales, with the richness of annotations present in other genome browsers. We give access to our system through a web-based interface that provides the user with an interactive representation that can be updated in real time using the mouse to move from region to region and to zoom in on interesting details.

    Scientists prefer not having to be tied down to a specific machine or operating system in order to analyze local and remote data sets or publish work. Increasingly, analysis has been migrating to decentralized web services and data sets, using web clients to provide the analysis interface. While simplifying workflow access, analysis, and publishing of data, the move does bring with it its own unique set of issues. Web clients used for analysis typically offer workflows geared towards a single user, with steps and results that are often difficult to recreate and share with others. Furthermore, workflow results often may not be easily used as input for further analysis. Older browsers further complicate things by having no way to maintain larger chunks of information, often offloading the job of storage to the back-end server or trying to squeeze it into a cookie. It has been difficult to provide a concept of "session storage" or "workflow sharing" without a complex orchestration of the back-end for storage depending on either a centralized file system or database. With the advent of HTML5, browsers gained the ability to store more information through the use of the Web Storage API (a browser-cookie holds a maximum of 4 kilobytes). Web Storage gives us the ability to store megabytes of arbitrary data in-browser either with an expiration date or just for a session. This allows scientists to create, update, persist and share their workflow without depending on the backend to store session information, providing the flexibility for new web-based workflows to emerge. In the DSASWeb portal ( http://cida.usgs.gov/DSASweb/ ), using these techniques, the representation of every step in the analyst's workflow is stored as plain-text serialized JSON, which we can generate as a text file and provide to the analyst as an upload. This file may then be shared with others and loaded back into the application, restoring the application to the state it was in when the session file

    Composites are prepared by deposition of nanoparticles of RuO{sub 2}.xH{sub 2}O (1-4 nm) on two carbons: microporous carbon (1.3 nm of average micropore size) and mesoporous carbon (11 nm of average mesopore size). Two-preparation procedures are used: (i) procedure A consisting of repetitive impregnations of the carbons with RuCl{sub 3}.0.5H{sub 2}O solutions, and (ii) procedure B based on impregnation of the carbons with Ru(acac){sub 3} vapour. The procedure B leads to supported RuO{sub 2}.xH{sub 2}O particles that appear more crystalline than those obtained by the procedure A. Specific capacitance and specific surface area of the composites are discussed as functions of the RuO{sub 2} content, and different dependences for the composites derived from the two carbons are found. Mesoporous carbon is better support than microporous carbon. Procedure A leads to supported RuO{sub 2}.xH{sub 2}O particles with higher specific capacitance than the particles deposited by procedure B.

    2016-03-01

    In the target paper [1], M.A. Arbib proposes a quite exhaustive review of the (often computational) models developed during the last decades that support his detailed scenario on language evolution (the Mirror System Hypothesis, MSH). The approach considers that language evolved from a mirror system for grasping already present in LCA-m (the last common ancestor of macaques and humans), to a simple imitation system for grasping present in LCA-c (the last common ancestor of chimpanzees and humans), to a complex imitation system for grasping that developed in the hominid line since that ancestor. MSH considers that this complex imitation system is a key evolutionary step for a language-ready brain, providing all the required elements for an open-ended gestural communication system. The transition from the gestural (bracchio-manual and visual) to the vocal (articulatory and auditory) domain is supposed to be a less important evolutionary step.

    2016-01-01

    Full Text Available The purpose of this randomized controlled study is to investigate the clinical results obtained over four years and incidence of complications associated with one- versus two-piece custom made zirconia anchorages, in single tooth implant-supported restorations of the maxillary anterior region. Sixty-five patients, with a total of 74 missing maxillary teeth, were selected in the period from February 2007 to July 2010. Two different ways of custom made zirconia abutment and final prosthetic restoration were evaluated: a standard zirconia abutment associated with a pressed layer of lithium disilicate with an all-ceramic cemented restoration versus one-piece restoration with the facing porcelain fired and pressed straight to the custom made zirconia abutment. In 29 cases, the restoration consisted of an all-ceramic restoration for cementation (two pieces; in 45 cases the restoration was a screw-retained restoration (one piece. Three all-ceramic restorations broke during the observation time. Two one-piece restorations fractured after 26 months. At follow-up examination there were no significant differences between one-piece and two-piece groups regarding the PI, BI, and MBL. Awaiting studies with longer follow-up times, a careful conclusion is that zirconia anchorages for single-implant restorations seem to demonstrate good short-term technical and biological results.

    1997-01-01

    Full Text Available The aim of the paper is to compare the role of the facilitator with the role of the librarian. Firstly, a list of the role dimensions of the facilitation is described. Secondly, a case study of a facilitation proces is presented. Thirdly, the intermediary functions of the librarian is considered. The comparison shows that the similarities between the two roles concerns the communication, the identification of information needs and the translation of the user formulations into a systematized terminology. Moreover, we cannot exclude that two elements of the librarian's information seeking process; i.e., the searching activity and the evaluation of the results, may exist in the work of the facilitator. Still, the important difference is, that the information seeking process, carried out of the facilitator, may be based not on the information needs of the user but on the predetermined outcome of the communication process. However, a more explicit work with the functions of the librarian; i.e.. both the searching activity and the evaluation of the results, during a networked communication process, may strengthen the group understanding development. In this way, the role of the librarian could develop the role of the facilitator. At the same time, the attention of the facilitator to the needs of the group could bring an important aspect into the role of the librarian.

    With the hope of applying laser-induced breakdown spectroscopy (LIBS) to the geological logging field, a series of cutting samples were classified using LIBS coupled with chemometric methods. In this paper, we focused on a comparative investigation of the linear PLS-DA method and non-linear SVM method. Both the optimal PLS-DA model and SVM model were built by the leave-one-out cross-validation (LOOCV) approach with the calibration LIBS spectra, and then tested by validation spectra. We show that the performance of SVM is significantly better than PLS-DA because of its ability to address the non-linear relationships in LIBS spectra, with a correct classification rate of 91.67% instead of 68.34%, and an unclassification rate of 3.33% instead of 28.33%. To further improve the classification accuracy, we then designed a new classification approach by the joint analysis of PLS-DA and SVM models. With this method, 95% of the validation spectra are correctly classified and no unclassified spectra are observed. This work demonstrated that the coupling of LIBS with the non-linear SVM method has great potential to be used for on-line classification of geological cutting samples, and the combination of PLS-DA and SVM enables the cuttings identification with an excellent performance. - Highlights: • The geological cuttings were classified using LIBS coupled with chemometric methods. • The non-linear SVM showed significantly better performance than PLS-DA. • The joint analysis of PLS-DA and SVMs provided an excellent accuracy of 95%.

    The inclusion of students with Autism Spectrum Disorder (ASD) in schools is a source of stress for teachers. Specialized teachers have, in theory, received special training. To compare the experiences of teachers dealing with students with ASD in different classroom environments. A total of 245 teachers filled out four self-report questionnaires measuring perceived stress, social support, coping strategies, and burnout. Specialized teachers perceive their teaching as a challenge, can count on receiving help from colleagues, use more problem-focused coping strategies and social support seeking behavior, and are less emotionally exhausted than teachers in regular classes. This study highlights that teachers in specialized schools and classes have better adjustment, probably due to their training, experience, and tailored classroom conditions. PMID:27282858

    The purposes of this study are to compare the current Space Shuttle Ground Support Equipment (GSE) infrastructure with the proposed GSE infrastructure upgrade modification. The methodology will include analyzing the first prototype installation equipment at Launch PAD B called the "Pathfinder". This study will begin by comparing the failure rate of the current components associated with the "Hardware interface module (HIM)" at the Kennedy Space Center to the failure rate of the neW Pathfinder components. Quantitative data will be gathered specifically on HIM components and the PAD B Hypergolic Fuel facility and Hypergolic Oxidizer facility areas which has the upgraded pathfinder equipment installed. The proposed upgrades include utilizing industrial controlled modules, software, and a fiber optic network. The results of this study provide evidence that there is a significant difference in the failure rates of the two studied infrastructure equipment components. There is also evidence that the support staff for each infrastructure system is not equal. A recommendation to continue with future upgrades is based on a significant reduction of failures in the new' installed ground system components.

    2014-09-01

    Full Text Available Cameroon is committed to reducing emissions from deforestation and forest degradation plus conservation, sustainable management of forests and enhancement of carbon stocks (REDD+. To achieve this goal, the government has introduced a series of policy reforms and formulated a number of key strategic planning documents to advance the REDD+ readiness process in Cameroon. This paper assesses the extent to which major cross-sectoral policies support or impede the development and implementation of an optimal REDD+ strategy in Cameroon from a comparative multi-criteria perspective. Study results reveal that a majority of the policy instruments reviewed appeared to be less prescriptive in terms of any tangible REDD+ strategy, as they do not have provisions for tangible measures to reduce deforestation and forest degradation. Given the lack of adequate flexibility, prompt review and responsiveness of these cross-sectoral policies to adapt themselves to new realities and respond to a changing environment, this paper introduces a GIS-REDD+ decision support system (GIS-REDD+DSS that is necessary to support the adaptive element of an adaptive REDD+ strategy in Cameroon. The GIS-REDD+DSS, an electronic REDD+agri intermediary hub, serves the following purpose: (1 host a database of locally-relevant climate information, improved input technologies, best practices as well as land use and forest cover geo-spatial maps; (2 host a virtual economic tool that performs economic valuations (costs and benefits and financial analysis of REDD+agri projects to aid investment decision-making; and (3 host an electronic marketplace to mediate any-to-any transactions among REDD+agri project developers, service providers, input suppliers, private and institutional investors and buyers (wholesalers and retailers, thereby creating value in two ways: aggregation and matching. This decision support tool, we argue, is a fundamental prerequisite for “policy and REDD+ safeguard

    Fabrice Lopez

    Full Text Available BACKGROUND: As public microarray repositories are constantly growing, we are facing the challenge of designing strategies to provide productive access to the available data. METHODOLOGY: We used a modified version of the Markov clustering algorithm to systematically extract clusters of co-regulated genes from hundreds of microarray datasets stored in the Gene Expression Omnibus database (n = 1,484. This approach led to the definition of 18,250 transcriptional signatures (TS that were tested for functional enrichment using the DAVID knowledgebase. Over-representation of functional terms was found in a large proportion of these TS (84%. We developed a JAVA application, TBrowser that comes with an open plug-in architecture and whose interface implements a highly sophisticated search engine supporting several Boolean operators (http://tagc.univ-mrs.fr/tbrowser/. User can search and analyze TS containing a list of identifiers (gene symbols or AffyIDs or associated with a set of functional terms. CONCLUSIONS/SIGNIFICANCE: As proof of principle, TBrowser was used to define breast cancer cell specific genes and to detect chromosomal abnormalities in tumors. Finally, taking advantage of our large collection of transcriptional signatures, we constructed a comprehensive map that summarizes gene-gene co-regulations observed through all the experiments performed on HGU133A Affymetrix platform. We provide evidences that this map can extend our knowledge of cellular signaling pathways.

    2011-01-01

    The ALMA Observation Support Tool (OST) is an ALMA simulator which is interacted with solely via a standard web browser. It is aimed at users who may or may not be experts in interferometry, or those that do not wish to familarise themselves with the simulation components of a data reduction package. It has been designed to offer full imaging simulation capability for an arbitrary ALMA observation while maintaining the accessibility of other online tools such as the ALMA Sensitivity Calculator. Simulation jobs are defined by selecting and entering options on a standard web form. The user can specify the standard parameters that would need to be considered for an ALMA observation (e.g. pointing direction, frequency set up, duration), and there is also the option to upload arbitrary sky models in FITS format. Once submitted, jobs are sequentially processed by a remote server running a CASA-based back-end system. The user is notified by email when the job is complete, and directed to a standard web page which co...

  12. Evaluation of radiological workstations and web-browser-based image distribution clients for a PACS project in hands-on workshops

    International Nuclear Information System (INIS)

    The methodology and outcome of a hands-on workshop for the evaluation of PACS (picture archiving and communication system) software for a multihospital PACS project are described. The following radiological workstations and web-browser-based image distribution software clients were evaluated as part of a multistep evaluation of PACS vendors in March 2001: Impax DS 3000 V 4.1/Impax Web1000 (Agfa-Gevaert, Mortsel, Belgium); PathSpeed V 8.0/PathSpeed Web (GE Medical Systems, Milwaukee, Wis., USA); ID Report/ID Web (Image Devices, Idstein, Germany); EasyVision DX/EasyWeb (Philips Medical Systems, Eindhoven, Netherlands); and MagicView 1000 VB33a/MagicWeb (Siemens Medical Systems, Erlangen, Germany). A set of anonymized DICOM test data was provided to enable direct image comparison. Radiologists (n=44) evaluated the radiological workstations and nonradiologists (n=53) evaluated the image distribution software clients using different questionnaires. One vendor was not able to import the provided DICOM data set. Another vendor had problems in displaying imported cross-sectional studies in the correct stack order. Three vendors (Agfa-Gevaert, GE, Philips) presented server-client solutions with web access. Two (Siemens, Image Devices) presented stand-alone solutions. The highest scores in the class of radiological workstations were achieved by ID Report from Image Devices (p<0.005). In the class of image distribution clients, the differences were statistically not significant. Questionnaire-based evaluation was shown to be useful for guaranteeing systematic assessment. The workshop was a great success in raising interest in the PACS project in a large group of future clinical users. The methodology used in the present study may be useful for other hospitals evaluating PACS. (orig.)

    It has been suggested that goats (typical browser) are better adapted to digest tannin-rich diets than sheep (typical grazer). To evaluate this, Bonga sheep and Kaffa goats were used in a 2 × 3 randomized crossover design with two species, three diets, and three periods (15-day adaptation + 7-day collection). The dietary treatments consisted of grass-based hay only (tannin-free diet = FT), a high-tannin diet (36% Albizia schimperiana (AS) + 9% Ficus elastica (FE) + 55% FT (HT)), and HT + polyethylene glycol 6000 (PEG). Animals were individually fed at 50 g dry matter (DM)/kg body weight (BW) and had free access to clean drinking water and mineralized salt licks. Nutrient intake, apparent nutrient digestibility, nutrient conversion ratios, and live weight changes were determined. Condensed tannin concentrations in AS and FE were 110 and 191 g/kg DM, respectively. Both sheep and goats ate 47% more of HT than FT, and dry matter intake further increased by 9% when PEG was added, with clear difference in effect size between goats and sheep (P effects of the tannin-rich diet and PEG addition were similarly positive for DM digestibility between sheep and goats, but crude protein (CP) digestibility was higher in HT + PEG-fed goats than in sheep fed the same diet. However, PEG addition induced a larger improvement in growth performance and feed efficiency ratio in sheep than in goat (P effect size in sheep. PMID:26519145

  15. Comparative Analysis of Logistic Regression, Support Vector Machine and Artificial Neural Network for the Differential Diagnosis of Benign and Malignant Solid Breast Tumors by the Use of Three-Dimensional Power Doppler Imaging

    International Nuclear Information System (INIS)

    Logistic regression analysis (LRA), Support Vector Machine (SVM) and a neural network (NN) are commonly used statistical models in computeraided diagnostic (CAD) systems for breast ultrasonography (US). The aim of this study was to clarify the diagnostic ability of the use of these statistical models for future applications of CAD systems, such as three-dimensional (3D) power Doppler imaging, vascularity evaluation and the differentiation of a solid mass. A database that contained 3D power Doppler imaging pairs of non-harmonic and tissue harmonic images for 97 benign and 86 malignant solid tumors was utilized. The virtual organ computer-aided analysis-imaging program was used to analyze the stored volumes of the 183 solid breast tumors. LRA, an SVM and NN were employed in comparative analyses for the characterization of benign and malignant solid breast masses from the database. The values of area under receiver operating characteristic (ROC) curve, referred to as Az values for the use of non-harmonic 3D power Doppler US with LRA, SVM and NN were 0.9341, 0.9185 and 0.9086, respectively. The Az values for the use of harmonic 3D power Doppler US with LRA, SVM and NN were 0.9286, 0.8979 and 0.9009, respectively. The Az values of six ROC curves for the use of LRA, SVM and NN for non-harmonic or harmonic 3D power Doppler imaging were similar. The diagnostic performances of these three models (LRA, SVM and NN) are not different as demonstrated by ROC curve analysis. Depending on user emphasis for the use of ROC curve findings, the use of LRA appears to provide better sensitivity as compared to the other statistical models

  16. Randomized phase III study comparing best supportive care to biafine as a prophylactic agent for radiation-induced skin toxicity for women undergoing breast irradiation: Radiation therapy oncology group (RTOG) 97-13

    International Nuclear Information System (INIS)

    Purpose: To determine if Biafine compared to Best Supportive Care (BSC) is effective in minimizing or preventing radiation-induced dermatitis in women undergoing breast irradiation. Methods and Materials: Patients were randomized between Biafine (n = 83) vs. BSC (n = 89). The institutions identified preference for BSC at the time of randomization. A no-treatment arm was allowed (16% received no treatment). Patients were instructed to apply randomized product three times a day, but not within 4 h of their daily RT session. Application began following their first radiation treatment and continued 2 weeks postradiation. Skin dermatitis was scored weekly utilizing the RTOG and ONS (Oncology Nursing Society) skin toxicity scales, a weekly patient satisfaction and quality-of-life questionnaire. Results: Using the RTOG toxicity scale there was no overall difference for maximum dermatitis during RT between Biafine and BSC (p = 0.77). There was no difference in maximum toxicity by arm or breast size. There was an interaction between breast size and toxicity, with large-breasted women exhibiting more toxicity. Large-breasted women receiving Biafine were more likely to have no toxicity 6 weeks post RT. Conclusion: There was no overall difference between BSC and Biafine in the prevention, time to, or duration of radiation-induced dermatitis.

    With the prevalence of the Web, most decision-makers are likely to use the Web to support their decision-making. Web-based technologies are leading a major stream of researching decision support systems (DSS). We propose a formal definition and a conceptual framework for Web-based open DSS (WODSS). The formal definition gives an overall view of WODSS, and the conceptual framework based on browser/broker/server computing mode employs the electronic market to mediate decision-makers and providers, and facilitate sharing and reusing of decision resources. We also develop an admitting model, a trading model and a competing model of electronic market in WODSS based on market theory in economics. These models reveal the key mechanisms that drive WODSS operate efficiently.

  19. Computational Tools for Brassica–Arabidopsis Comparative Genomics

    Directory of Open Access Journals (Sweden)

    2006-04-01

    Full Text Available Recent advances, such as the availability of extensive genome survey sequence (GSS data and draft physical maps, are radically transforming the means by which we can dissect Brassica genome structure and systematically relate it to the Arabidopsis model. Hitherto, our view of the co-linearities between these closely related genomes had been largely inferred from comparative RFLP data, necessitating substantial interpolation and expert interpretation. Sequencing of the Brassica rapa genome by the Multinational Brassica Genome Project will, however, enable an entirely computational approach to this problem. Meanwhile we have been developing databases and bioinformatics tools to support our work in Brassica comparative genomics, including a recently completed draft physical map of B. rapa integrated with anchor probes derived from the Arabidopsis genome sequence. We are also exploring new ways to display the emerging Brassica–Arabidopsis sequence homology data. We have mapped all publicly available Brassica sequences in silico to the Arabidopsis TIGR v5 genome sequence and published this in the ATIDB database that uses Generic Genome Browser (GBrowse. This in silico approach potentially identifies all paralogous sequences and so we colour-code the significance of the mappings and offer an integrated, real-time multiple alignment tool to partition them into paralogous groups. The MySQL database driving GBrowse can also be directly interrogated, using the powerful API offered by the Perl Bio∷DB∷GFF methods, facilitating a wide range of data-mining possibilities.

    The Mental Health Commission of Canada defines peer support as "a supportive relationship between people who have a lived experience in common … in relation to a mental health challenge or illness … related to their own mental health or that of a loved one" (Sunderland et al. 2013: 11). In Ontario, a key resource for peer support is the Ontario Peer Development Initiative (OPDI), which is an umbrella organization of mental health Consumer/Survivor Initiatives (CSIs) and peer support organizations across the province of Ontario. Member organizations are run by and for people with lived experience of a mental health or addiction issue and provide a wide range of services and activities within their communities. The central tenet of member organizations is the common understanding that people can and do recover with the proper supports in place and that peer support is integral to successful recovery. Nationally, Peer Support Accreditation and Certification Canada has recently been established. The relatively new national organization focuses on training and accrediting peer support workers. This paper focuses on a range of diverse peer support groups and CSIs that operate in London and surrounding areas. PMID:26854546

    International Nuclear Information System (INIS)

    A method for the configuration of informatics systems that provide support to DICOM standards using XML files is proposed. The difference with other proposals is base on that this system does not code the information of a DICOM objects file, but codes the standard itself in an XML file. The development itself is the format for the XML files mentioned, in order that they can support what DICOM normalizes for multiple languages. In this way, the same configuration file (or files) can be use in different systems. Jointly the XML configuration file generated, we wrote also a set of CSS and XSL files. So the same file can be visualized in a standard browser, as a query system of DICOM standard, emerging use, that did not was a main objective but brings a great utility and versatility. We exposed also some uses examples of the configuration file mainly in relation with the load of DICOM information objects. Finally, at the conclusions we show the utility that the system has already provided when the edition of DICOM standard changes from 2006 to 2007

    2004-01-01

    Comparison of DNA sequences from different species is a fundamental method for identifying functional elements in genomes. Here we describe the VISTA family of tools created to assist biologists in carrying out this task. Our first VISTA server at http://www-gsd.lbl.gov/VISTA/ was launched in the summer of 2000 and was designed to align long genomic sequences and visualize these alignments with associated functional annotations. Currently the VISTA site includes multiple comparative genomics tools and provides users with rich capabilities to browse pre-computed whole-genome alignments of large vertebrate genomes and other groups of organisms with VISTA Browser, submit their own sequences of interest to several VISTA servers for various types of comparative analysis, and obtain detailed comparative analysis results for a set of cardiovascular genes. We illustrate capabilities of the VISTA site by the analysis of a 180 kilobase (kb) interval on human chromosome 5 that encodes for the kinesin family member3A (KIF3A) protein.

  9. A comparative study of CeO2-Al2O3 support prepared with different methods and its application on MoO3/CeO2-Al2O3 catalyst for sulfur-resistant methanation

    International Nuclear Information System (INIS)

    The CeO2-Al2O3 supports prepared with impregnation (IM), deposition precipitation (DP), and solution combustion (SC) methods for MoO3/CeO2-Al2O3 catalyst were investigated in the sulfur-resistant methanation. The supports and catalysts were characterized by N2-physisorption, transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy (RS), and temperature-programmed reduction (TPR). The N2-physisorption results indicated that the DP method was favorable for obtaining better textural properties. The TEM and RS results suggested that there is a CeO2 layer on the surface of the support prepared with DP method. This CeO2 layer not only prevented the interaction between MoO3 and γ-Al2O3 to form Al2(MoO4)3 species, but also improved the dispersion of MoO3 in the catalyst. Accordingly, the catalysts whose supports were prepared with DP method exhibited the best catalytic activity. The catalysts whose supports were prepared with SC method had the worst catalytic activity. This was caused by the formation of Al2(MoO4)3 and crystalline MoO3. Additionally, the CeO2 layer resulted in the instability of catalysts in reaction process. The increasing of calcination temperature of supports reduced the catalytic activity of all catalysts. The decrease extent of the catalysts whose supports were prepared with DP method was the lowest as the CeO2 layer prevented the interaction between MoO3 and γ-Al2O3.

    2015-01-01

    We aim to ease the process of authoring accessible graphics as well as taking a first step towards the long-term goal of allowing blind persons to access graphics autonomously. We are developing and experimenting with a hierarchical set of knowledge bases related to the presentation of visual objects and cues in the form of ontologies that will act as the formal, axiomatic underpinnings of an accessibility layer or, later on, a graphics reader/browser for blind and visually impaired people. The concept and prototypes of smart (or communicative) graphics [1], in which readers obtain information about the syntactic and semantic content through the use of e.g. a natural language interface, should be expanded by exploiting the benefits of formal semantics supported by domain- and task-aware ontologies describing the elements, visual cues and relations used for visualization or visual display.

    Since the National Bridge Inventory (NBI) was first conducted, structural health monitoring (SHM) of U.S. bridge infrastructure has consisted largely of time and labor-intensive surveys with subjective results. In-situ and embedded sensors, while more reliable and accurate, can be costly and in many cases infeasible for SHM because they require installation in hard-to-reach places or during construction. Remote sensing (RS) technologies such as radar, electrooptical imaging and laser scanning may offer an innovative, cost-effective method of monitoring the dynamic conditions of U.S. bridges in real-time. While some RS techniques may be costly for state agencies to deploy on their own, RS imagery is available through government agencies or commercial vendors for moderate or no cost. How can disparate RS datasets be integrated with one another and with inventory data in a way that is meaningful to bridge asset management decision makers? This paper discusses the development and functionality of the Bridge Condition Decision Support System (DSS), a web-based asset management tool for bridge managers and inspectors. The DSS seamlessly merges bridge metrics from RS data with NBI inventory data allowing decision makers to compare up-to-date bridge condition metrics from multiple inputs as a time series. It enables analysis of RS and inventory data available through user-friendly web services which can also expose virtually unlimited server-side data processing. Using open-source software, the authors developed a scalable, spatially-aware bridge condition database with a fast and flexible server application programming interface (API) and a cross-browser compatible web mapping application written in Javascript.

  12. SU-D-BRD-01: An Automated Physics Weekly Chart Checking System Supporting ARIA

    Energy Technology Data Exchange (ETDEWEB)

    Chang, X; Yang, D [Washington University in St Louis, St Louis, MO (United States)

    2015-06-15

    Purpose: A software tool was developed in this study to perform automatic weekly physics chart check on the patient data in ARIA. The tool accesses the electronic patient data directly from ARIA server and checks the accuracy of treatment deliveries, and generates reports which summarize the delivery history and highlight the errors. Methods: The tool has four modules. 1) The database interface is designed to directly access treatment delivery data from the ARIA database before reorganizing the data into the patient chart tree (PCT). 2) PCT is a core data structure designed to store and organize the data in logical hierarchies, and to be passed among functions. 3) The treatment data check module analyzes the organized data in PCT and stores the checking results into PCT. 4) Report generation module generates reports containing the treatment delivery summary, chart checking results and plots of daily treatment setup parameters (couch table positions, shifts of image guidance). The errors that are found by the tool are highlighted with colors. Results: The weekly check tool has been implemented in MATLAB and clinically tested at two major cancer centers. Javascript, cascading style sheets (CSS) and dynamic HTML were employed to create the user-interactive reports. It takes 0.06 second to search the delivery records of one beam with PCT and compare the delivery records with beam plan. The reports, saved in the HTML files on shared network folder, can be accessed by web browser on computers and mobile devices. Conclusion: The presented weekly check tool is useful to check the electronic patient treatment data in Varian ARIA system. It could be more efficient and reliable than the manually check by physicists. The work was partially supported by a research grant from Varian Medical System.

    Krumm, S.; Thum, I.

    1998-08-01

    The hypertext mark-up language (HTML) is used to create hypertext documents in use on the World-Wide Web (WWW), built up as a client/server model. In this paper we discuss the enhancement of HTML documents with JavaScript, a script language understood by most common browsers. JavaScript is considered an easy means for bringing interactivity and answer checking to educational Web pages. It is faster to learn compared to using a programming language like PERL and has the advantage of high portability between different operating systems. Because all actions are performed on the client side, it reduces net traffic and pages can be used off-line. Educational usage, including tests and operations in future distance learning are outlined. Examples of JavaScript supported documents are given using clay mineralogy and knowledge-based tests as examples. A critical review of this relatively new technology reveals some compatibility problems but these seem to be offset by the possibility to make Web pages more attractive.

    This chapter takes its point of departure in psychosocial aspects of supportive care in adolescent and young adult cancer care. The purpose is to describe some of the challenges that these young people face following a cancer diagnosis and guide healthcare professionals in how to provide care that improves the quality of life. In most hospitals and healthcare systems, adolescents and young adults are cared for and treated in settings for children or adults. Accordingly, healthcare professionals may lack attention to and knowledge about what characterize young peoples' life situation, their special needs and how to meet them. The topics we include in the chapter are the following: the youth friendly environment, social support and social network, parents, information during a psychosocial crisis event, the use of HEADSS, peer support, fertility, body image and self-esteem, after treatment and future challenges and palliative and end of life care.

    This paper empirical analyzes the support effect and different influence of the micro-finance on small micro-enterprise development by the VAR model, the granger causality test, and impulse response function and variance decomposition methods. The empirical results found that the micro-finance has a limited and lag support effect on the micro-enterprise's development. In comparison, direct financing market has a significant support effect on the development of small micro-enterprise, but indirect financing market is far from meeting the requirements of the development of small micro-enterprise. Therefore, we should further broaden the small micro-enterprise financing channels for small micro-enterprise, continue to strengthen the indirect financing market's support effect for small micro enterprise development and guide the different financial institutions in micro-finance service to position reasonably, while make every effort to develop the direct financing market in order to better serve the development of small micro-enterprise.%运用VAR模型,通过格兰杰非因果检验、结合脉冲响应函数及方差分解方法,实证分析了我国微型金融对小微企业的支持力度以及影响的差异性。实证结果表明:我国微型金融对小微企业发展的支持效应滞后且力度有限。相比较而言,直接融资方式对小微企业发展的支持力度较显著,而间接融资对小微企业的支持力度远远不能满足小微企业的发展需要。因此,要进一步拓宽小微企业融资渠道,强化间接融资对小微企业发展的支持力度,引导不同的金融机构在微型金融服务中合理定位,同时大力发展为小微企业服务的直接融资市场,形成多渠道、多元化的微型金融服务体系,更有效地支持小微企业发展。

    2008-03-01

    Full Text Available Abstract Background The conservation of gene order among prokaryotic genomes can provide valuable insight into gene function, protein interactions, or events by which genomes have evolved. Although some tools are available for visualizing and comparing the order of genes between genomes of study, few support an efficient and organized analysis between large numbers of genomes. The Prokaryotic Sequence homology Analysis Tool (PSAT is a web tool for comparing gene neighborhoods among multiple prokaryotic genomes. Results PSAT utilizes a database that is preloaded with gene annotation, BLAST hit results, and gene-clustering scores designed to help identify regions of conserved gene order. Researchers use the PSAT web interface to find a gene of interest in a reference genome and efficiently retrieve the sequence homologs found in other bacterial genomes. The tool generates a graphic of the genomic neighborhood surrounding the selected gene and the corresponding regions for its homologs in each comparison genome. Homologs in each region are color coded to assist users with analyzing gene order among various genomes. In contrast to common comparative analysis methods that filter sequence homolog data based on alignment score cutoffs, PSAT leverages gene context information for homologs, including those with weak alignment scores, enabling a more sensitive analysis. Features for constraining or ordering results are designed to help researchers browse results from large numbers of comparison genomes in an organized manner. PSAT has been demonstrated to be useful for helping to identify gene orthologs and potential functional gene clusters, and detecting genome modifications that may result in loss of function. Conclusion PSAT allows researchers to investigate the order of genes within local genomic neighborhoods of multiple genomes. A PSAT web server for public use is available for performing analyses on a growing set of reference genomes through any

    Prothero, W. A.

    2003-12-01

    The purpose of the EarthEd Online software project is to support a modern instructional pedagogy in a large, college level, earth science course. It is an ongoing development project that has evolved in a large general education oceanography course over the last decade. Primary goals for the oceanography course are to support learners in acquiring a knowledge of science process, an appreciation for the relevance of science to society, and basic content knowledge. In order to support these goals, EarthEd incorporates: a) integrated access to various kinds of real earth data (and links to web-based data browsers), b) online discussions, live chat, with integrated graphics editing, linking, and upload, c) online writing, reviewing, and grading, d) online homework assignments, e) on demand grade calculation, and f) instructor grade entry and progress reports. The software was created using Macromedia Director. It is distributed to students on a CDROM and updates are downloaded and installed automatically. Data browsers for plate tectonics relevant data ("Our Dynamic Planet"), a virtual exploration of the East Pacific Rise, the World Ocean Atlas-98, and a fishing simulation game are integrated with the EarthEd software. The system is modular which allows new capabilities, such as new data browsers, to be added. Student reactions to the software are positive overall. They are especially appreciative of the on demand grade computation capability. The online writing, commenting and grading is particularly effective in managing the large number of papers that get submitted. The TA's grade the papers, but the instructor can provide feedback to them as they grade the papers, and a record is maintained of all comments and rubric item grades. Commenting is made easy by simply "dragging" a selection of pre-defined comments into the student's text. Scoring is supported by an integrated scoring rubric. All assignments, rubrics, etc. are configured in text files that are downloaded

  11. Corrosion of support materials

    International Nuclear Information System (INIS)

    Results from a heavily fouled 19 tube C-E model boiler test to investigate the potential for egg crate corrosion in aggressively fouled AVT chemistry are reported. Substantial support plate and egg crate corrosion was produced in this test. Carbon steel drilled support plates exhibited extensive denting which resulted in flow hole ligament cracking. Corrosion of the carbon steel egg crate, through-wall at areas of tube contact, resulted in denting of the Alloy 600 heat transfer tubes. Corrosion performance of the 409 stainless steel egg crate was improved compared to the carbon steel egg crate although localized through-wall corrosion was noted. The results from the above test and previously reported tests were compared based on the following simplifying assumptions: maximum dent size and/or corrosion penetrations utilized, average bulk water chloride concentrations, pilling bedworth ratios, pot and model boilers data are equivalent, heat flux not significantly variable, and plot is semi-quantitative. Conclusions based on plots of maximum corrosion rates as a function of average bulk water chloride concentrations are presented. Finally, the corrosion performance of the various materials of construction for support systems were ranked for each test. Final material selection for future support systems must be based on a balance of thermal/hydraulic, metallurgical, corrosion and design considerations

    Logistical packaging is conducted to furnish protection, utility, and communication for elements of a logistical system. Once the functional requirements of space logistical support packaging have been identified, decision-makers have a reasonable basis on which to compare package alternatives. Flexible packages may be found, for example, to provide adequate protection and superior utility to that of rigid packages requiring greater storage and postuse waste volumes.

    Clustering is the preferred choice of method in many applications, and support vector clustering (SVC) has proven efficient for clustering noisy and high-dimensional data sets. A method for multiscale support vector clustering is demonstrated, using the recently emerged method for fast calculation of the entire regularization path of the support vector domain description. The method is illustrated on artificially generated examples, and applied for detecting blood vessels from high resolution time series of magnetic resonance imaging data. The obtained results are robust while the need for parameter estimation is reduced, compared to support vector clustering.

  16. Support and development for remote collaboration in fusion research

    International Nuclear Information System (INIS)

    Major fusion experiments and modeling efforts rely on joint research of scientists from several locations around the world. A variety of software tools are in use to provide remote interactive access to facilities and data are routinely available over wide-area-network connections to researchers. Audio and video communications, monitoring of control room information and synchronization of remote sites with experimental operations all enhance participation during experiments. Remote distributed computing capabilities allow utilization of off-site computers that now help support the demands of control room analyses and plasma modeling. A collaborative software development project is currently using object technologies with CORBA-based communications to build a network executable transport code that further demonstrates the ability to utilize geographically dispersed resources. Development to extend these concepts with security and naming services and possible applications to instrumentation systems has been initiated. An Information Technology Initiative is deploying communication systems, ISDN (telephone) and IP (network) audio/video (A/V) and web browser-based, to build the infrastructure needed to support remote physics meetings, seminars and interactive discussions

    Gramene (http://www.gramene.org) is an online resource for comparative functional genomics in crops and model plant species. Its two main frameworks are genomes (collaboration with Ensembl Plants) and pathways (The Plant Reactome and archival BioCyc databases). Since our last NAR update, the database website adopted a new Drupal management platform. The genomes section features 39 fully assembled reference genomes that are integrated using ontology-based annotation and comparative analyses, and accessed through both visual and programmatic interfaces. Additional community data, such as genetic variation, expression and methylation, are also mapped for a subset of genomes. The Plant Reactome pathway portal (http://plantreactome.gramene.org) provides a reference resource for analyzing plant metabolic and regulatory pathways. In addition to ∼ 200 curated rice reference pathways, the portal hosts gene homology-based pathway projections for 33 plant species. Both the genome and pathway browsers interface with the EMBL-EBI's Expression Atlas to enable the projection of baseline and differential expression data from curated expression studies in plants. Gramene's archive website (http://archive.gramene.org) continues to provide previously reported resources on comparative maps, markers and QTL. To further aid our users, we have also introduced a live monthly educational webinar series and a Gramene YouTube channel carrying video tutorials. PMID:26553803

    During the last years, the ubiquity of web interfaces have pushed practically all PACS suppliers to develop client applications in which clinical practitioners can receive and analyze medical images, using conventional personal computers and Web browsers. However, due to security and performance issues, the utilization of these software packages has been restricted to Intranets. Paradigmatically, one of the most important advantages of digital image systems is to simplify the widespread sharing and remote access of medical data between healthcare institutions. This paper analyses the traditional PACS drawbacks that contribute to their reduced usage in the Internet and describes a PACS based on Web Services technology that supports a customized DICOM encoding syntax and a specific compression scheme providing all historical patient data in a unique Web interface.

    International Nuclear Information System (INIS)

    An extensive development effort has resulted in the successful application of energy absorbers as alternative supports. Several installations of energy absorbers demonstrating the feasibility of this support concept have been successfully completed. Designed in accordance with the ASME Code Case N-420, these ductile supports undergo limited and controlled yielding under dynamic conditions, thereby dissipating energy. The design methodology determines the specific damping ratios applicable for a given piping system on the basis of the energy absorbers used. Thus, using energy absorbers permits predictable damping to be engineered into the system desing. They can be used in operating plants to replace existing snubbers. In plants under construction, they can be used in place of both snubbers and rigid supports. In both applications, fewer energy absorbers are required as compared to snubbers and rigid supports.

    Comparative genomics provides the means to demarcate functional regions in anonymous DNA sequences. The successful application of this method to identifying novel genes is currently shifting to deciphering the noncoding encryption of gene regulation across genomes. To facilitate the use of comparative genomics to practical applications in genetics and genomics we have developed several analytical and visualization tools for the analysis of arbitrary sequences and whole genomes. These tools include two alignment tools: zPicture and Mulan; a phylogenetic shadowing tool: eShadow for identifying lineage- and species-specific functional elements; two evolutionary conserved transcription factor analysis tools: rVista and multiTF; a tool for extracting cis-regulatory modules governing the expression of co-regulated genes, CREME; and a dynamic portal to multiple vertebrate and invertebrate genome alignments, the ECR Browser. Here we briefly describe each one of these tools and provide specific examples on their practical applications. All the tools are publicly available at the http://www.dcode.org/ web site.

    1997-02-01

    Under funding from the Defense Advanced Research Projects Agency (DARPA) for joint military and law enforcement technologies, demonstrations of secure information transfer in support of law enforcement and military operations other than war, using wireless and wired technology, were held in September 1996 at several locations in the United States. In this paper, the network architecture, protocols, and equipment supporting the demonstration's scenarios are presented, together with initial results, including lessons learned and desired system enhancements. Wireless networks of opportunity encompassed in-building (wireless-LAN), campus-wide (Metricom Inc.), metropolitan (AMPS cellular, CDPD), and national (one- and two-way satellite) systems. Evolving DARPA-sponsored packet radio technology was incorporated. All data was encrypted, using multilevel information system security initiative (MISSI)FORTEZZA technology, for carriage over unsecured and unclassified commercial networks. The identification and authentication process inherent in the security system permitted logging for database accesses and provided an audit trail useful in evidence gathering. Wireless and wireline communications support, to and between modeled crisis management centers, was demonstrated. Mechanisms for the guarded transport of data through the secret-high military tactical Internet were included, to support joint law enforcement and crisis management missions. A secure World Wide Web (WWW) browser forms the primary, user-friendly interface for information retrieval and submission. The WWW pages were structured to be sensitive to the bandwidth, error rate, and cost of the communications medium in use (e.g., the use of and resolution for graphical data). Both still and motion compressed video were demonstrated, along with secure voice transmission from laptop computers in the field. Issues of network bandwidth, airtime costs, and deployment status are discussed.

    Full Text Available AbstractIn the fourth in this series of ‘comparative healthcare’ medical practitioners explore the approach to mentalillness in Bangladesh and the UK respectively. Differences and similarities in treatment regimens are illustratedwith reference to patients with varying degrees of mental illness. Mental illness poses the greatest challenge inhealth care as national investment in services often reflects cultural attitudes and norms. While the authorsdescribe very similar approaches to the diagnosis and management of severe psychotic illness there are strikingdifferences in the availability of support services for people with substance abuse and those with relapsingconditions. The involvement and co-operation of the family is particularly important in Bangladesh wherecomprehensive access to mental health services is very limited. Private alcohol and drug detoxification centresare available although many are expensive and such treatment may effectively be denied to all but the wealthiestpeople. In the UK all people with serious and enduring mental illness are entered onto a register and thereforeflagged for follow up at least once a year. General Practitioners, working within the nationally funded healthservice have been remunerated since 2003 for maintaining the register. In contrast in the absence of a casemanagementbased psychiatric follow-up framework in Bangladesh, a general practitioner and treatingpsychiatrist would need to formulate a management plan involving recognition of clinical warning signs by thefamily. Indeed the co-operation and support of the patient’s family is of paramount importance in maintainingoutpatient appointments when supporting people with mental health problems in Bangladesh. Finally weemphasise that the views expressed are those of the authors and do not necessarily reflect health policy orpractice in their respective countries. Nonetheless we believe they offer a valuable perspective on mental healthissues and

    AgBase (http://www.agbase.msstate.edu/) provides resources to facilitate modeling of functional genomics data and structural and functional annotation of agriculturally important animal, plant, microbe and parasite genomes. The website is redesigned to improve accessibility and ease of use, including improved search capabilities. Expanded capabilities include new dedicated pages for horse, cat, dog, cotton, rice and soybean. We currently provide 590 240 Gene Ontology (GO) annotations to 105 454 gene products in 64 different species, including GO annotations linked to transcripts represented on agricultural microarrays. For many of these arrays, this provides the only functional annotation available. GO annotations are available for download and we provide comprehensive, species-specific GO annotation files for 18 different organisms. The tools available at AgBase have been expanded and several existing tools improved based upon user feedback. One of seven new tools available at AgBase, GOModeler, supports hypothesis testing from functional genomics data. We host several associated databases and provide genome browsers for three agricultural pathogens. Moreover, we provide comprehensive training resources (including worked examples and tutorials) via links to Educational Resources at the AgBase website. PMID:21075795

  11. Design of decision support systems

    International Nuclear Information System (INIS)

    The paper is addressing the design of decision support systems to be used in the nuclear industry and the requirements placed on such systems. A general model of the decision-making situation is proposed for the structuring of the different functions provided by the decision support system. The relative merits of different functions of the support systems and their practical implementation are discussed. A proposal for the functions to be included in a decision support system is given as a result fo the discussion. The practical design of decision support system is discussed, and some general remarks on the management of design projects are given. The use of decision support systems and their integration in the every day routines are also discussed. Reference is given to experiments, where a large scale validation of decision support systems have been attempted. One of the findings from the validation experiments, is that it might be difficult or even impossible to prove the benefit of a proposed design of a decision support system in quantitative terms. Present design practices are bringing in the concern for the human as a part of the system comparatively late and in a rather unsystematic way. As a conclusion it is argued that more effort should be spent in building up an understanding of the dynamics of design projects. Such an understanding can be used to create better models for carrying out the design projects and to specify different design tools to be used. (author). 17 refs, 1 fig, 5 tabs

    2004-01-01

    In order to enable a wind tunnel support to have a high enough natural frequency to prevent experiencing mechanical resonance and excessive vibration displacement, five kinds of wind tunnel support structures have been simulated and analyzed individually under five different load conditions by means of a nonlinear finite element numerical method. With natural frequency and three directions vibration displacement given, simulation and analyses indicated that additional supports is more beneficial than heightening the rigidity of steel reinforced concrete in support pillars and adopting steel wrappers on the pillars to increase natural frequency of support structure. Increasing the rigidity of steel reinforced concrete, adopting steel wrappers and providing additional supports are all helpful in reducing three directions vibration Max displacement. and additional supports are comparatively more effective. Therefore, a structure scheme with steel reinforced concrete support pillars,steel wrappers and additional supports should be adopted in practical wind tunnel support construction.

  13. Decision Support for Radiologists

    Full Text Available Introduction & Background: Radiology practice like any other discipline in medicine consists of professional problem solving. A practicing radiologist may face different kinds of problems from pathology finding in im-age, suggestion of appropriate workup in a specific situation, formulating relevant differential diagnosis list for comparison with normal variants and artifacts. When a radiologist has the opportunity to use a computer he/she will also be able to use digital material/technology to solve these problems and make sound decisions. The available methods/materials for digital decision support in radiology may be categorized as follow: A. Image Processing When a radiological image is captured or converted to digital format, techniques like edge enhancement and contrast change may improve the diagnostic value of an image and help in decision making. B. Computer-aided Detection Thoracic imaging and mammography are two fields with promising advances in computer-aided diagnosis (CAD. The ultimate role of CAD is as a second opinion besides radiologists own perception. It is obvious how-ever that when available, CAD may decrease detection errors in radiology practice. C. Decision Support Databases Image Banks: An electronic atlas may be used to compare patients’ image to a predefined classified set of im-ages in order to help radiologist in pattern recognition. This may also be used for anatomic details and variants. Knowledge Bases: A digital differential diagnosis table or algorithmic approach to a specific problem may be helpful in reading room. Digital Textbooks: Classical radiological textbooks may be used in routine practice to remember some definitions, lists or hints, When available, digital version of textbooks are invaluable decision aids. D. Internet resources Online resources can be easily updated, widely used by different users, uniformly applied by different radiolo-gists. Although digital decision support materials and

    Full Text Available In recent years, information technology (IT becomes prominent to support teaching and learning activities. IT tools allow us to create, collect, store and use the information and knowledge. E-learning was one of IT tools introduced at College of Science and Technology (CST, University Technology Malaysia (UTM Kuala Lumpur since 2001. It has enabled a paradigm shift from institutio n-centered instruction to anywhere, anytime and anybody learning models. In CST the e-learning technology was used for accessing the syllabus and course content, submitting assignments, and taking class quizzes. This paper focuses on issues relating to the e-learning critical success factors (CSFs from university students’ perspective. In this study, two main factors related to the e-learning CSFs within a university environment included technological and institutional support factors were examined. Confirmatory factor modeling approach was used to assess the criticality of the measures included in each factor. The results indicated that the most critical measures for technological factor in terms of ease of access and infrastructure are the browser efficiency, course website ease of use and computer network reliability. Meanwhile, for institutional support factor, the most critical measure is the availability of technical support or help desk.

  17. Comparative finite element analysis of the cranial performance of four herbivorous marsupials.

    Sharp, Alana C

    2015-10-01

    Marsupial herbivores exhibit a wide variety of skull shapes and sizes to exploit different ecological niches. Several studies on teeth, dentaries, and jaw adductor muscles indicate that marsupial herbivores exhibit different specializations for grazing and browsing. No studies, however, have examined the skulls of marsupial herbivores to determine the relationship between stress and strain, and the evolution of skull shape. The relationship between skull morphology, biomechanical performance, and diet was tested by applying the finite element method to the skulls of four marsupial herbivores: the common wombat (Vombatus ursinus), koala (Phascolarctos cinereus), swamp wallaby (Wallabia bicolor), and red kangaroo (Macropus rufus). It was hypothesized that grazers, requiring stronger skulls to process tougher food, would have higher biomechanical performance than browsers. This was true when comparing the koala and wallaby (browsers) to the wombat (a grazer). The cranial model of the wombat resulted in low stress and high mechanical efficiency in relation to a robust skull capable of generating high bite forces. However, the kangaroo, also a grazer, has evolved a very different strategy to process tough food. The cranium is much more gracile and has higher stress and lower mechanical efficiency, but they adopt a different method of processing food by having a curved tooth row to concentrate force in a smaller area and molar progression to remove worn teeth from the tooth row. Therefore, the position of the bite is crucial for the structural performance of the kangaroo skull, while it is not for the wombat which process food along the entire tooth row. In accordance with previous studies, the results from this study show the mammalian skull is optimized to resist forces generated during feeding. However, other factors, including the lifestyle of the animal and its environment, also affect selection for skull morphology to meet multiple functional demands. PMID:26193997

    Primary reading or further evaluation of diagnostic imaging examination often needs a comparison between the actual findings and the relevant prior images of the same patient or similar radiological data found in other patients. This support is of clinical importance and may have significant effects on physicians' examination reading efficiency, service-quality, and work satisfaction. We developed a visual query-by-example image database for storing and retrieving chest CT images by means of a visual browser Image Management Environment (IME) and tested its retrieval efficiency. The visual browser IME included four fundamental features (segmentation, indexing, quick load and recall, user-friendly interface) in an integrated graphical environment for a user-friendly image database management. The system was tested on a database of 2000 chest CT images, randomly chosen from the digital archives of our institutions. A sample of eight heterogeneous images were used as queries and, for each of them a team of three expert radiologists selected the most similar images from the database (a set of 15 images containing similar abnormalities in the same position of the query). The sensitivity and the positive predictive factor, both averaged over the 8 test queries and 15 answers, were respectively 0.975 and 0.91 The IME system is currently under evaluation at our institutions as an experimental application. We consider it a useful work-in-progress tool for clinical practice facilitating searches for a variety of radiological tasks. PMID:15937719

    Two articles in the current issue of the Psychiatric Rehabilitation Journal bring into focus the important question of the importance of work, and in particular meaningful employment, in people with a serious mental illness. Gewurtz, Cott, Rush, and Kirsh (see record 2012-34112-003) present findings from a change in policy in Canada for the funding of vocational services for people with a serious mental illness from a fee-for-service model to an outcomes-based model, with reimbursement based on successful competitive job placement and retention, irrespective of job type and consumer preference. The results indicated increased rates of competitive work, mainly in entry-level jobs, but they also raised questions as to whether the narrow focus on job attainment may have been at the cost of less career development and ultimately less meaningful work for the consumers. Baksheev, Allott, Jackson, McGorry, and Killackey (see record 2012-34112-002) found that a combined supported employment and education program for people with a first episode of psychosis led to higher rates of employment and class completion than usual services. The analysis presented in this report showed that no individual consumer characteristics other than program assignment (supported employment and education vs. usual services) predicted vocational or educational outcomes. The findings underscore the potency of supported employment, and suggest that combining it with educational services may be fruitful for people who have recently experienced an episode of psychosis. These findings raise several questions that will be touched on in this editorial, including: Why are career development and supported education important? What have we learned about supported education? What are the current gaps in our knowledge about supported education? PMID:23276233

    2009-05-01

    Full Text Available In the third in this series of ‘comparative healthcare’ medical practitioners explore the approach to diabetes inBangaldesh and Australia respectively. The social and medical consequences of this chronic conditionare highlighted through the approach to patients at various stages of the disease from two nationalperspectives. An astonishing 7% of the 153 million people are reported to have diabetes in Bangladesh. Manyremain undiagnosed. Delays in diagnosis or management of diabetes have life limiting consequences for thosewho can ill afford private health care in the poorer nation. Screening and early intervention appear to bedenied to many in the developing country. The context is very different with Australians very fortunate to havea coordinated primary health care sector. The outlook for Bangladeshis with uncontrolled diabetes or withtreatable sequela would be unacceptable in Australia. At every stage in the disease trajectory the doctorsemphasise the importance of life style modification, a particular challenge in affluent Australia with its growingincidence of life style related pre morbid conditions in an increasingly sedentary population. A corner stone ofthe support of people with diabetes is the role of nurses and allied health professionals. With a fundedcommitment to multidisciplinary care in the community people with diabetes in Australia have access tosupport closer to home whereas those in Bangladesh remain heavily dependent on specialist, hospital basedservices. One can only speculate how Bangladesh will cope as its population ages and there are an everincreasing proportion of people who require urgent and expensive medical interventions. At the very leastthere is a strong case for greater investment in primary care especially to limit the economic consequences ofdiabetes and other chronic conditions. Finally as in other articles in this series we would like to emphasise that,the views expressed are those of the authors and do

  10. Supported microporous ceramic membranes

    Science.gov (United States)

    Webster, E.; Anderson, M.

    1993-12-14

    A method for the formation of microporous ceramic membranes onto a porous support includes placing a colloidal suspension of metal or metal oxide particles on one side of the porous support and exposing the other side of the porous support to a drying stream of gas or a reactive gas stream so that the particles are deposited on the drying side of the support as a gel. The gel so deposited can be sintered to form a supported ceramic membrane useful for ultrafiltration, reverse osmosis, or molecular sieving having mean pore sizes less than 100 Angstroms. 4 figures.

  12. Electrocatalyst-support interactions

    Energy Technology Data Exchange (ETDEWEB)

    Kinoshita, K.

    1978-01-01

    The maximum utilization of noble metals as heterogeneous catalysts is achieved by dispersing the noble metals as small particles supported on a porous, high surface area powder. In some studies with supported noble metal catalysts, it has been reported that the metal particle interacts with the support material and that the interaction affects the catalytic properties of the metal. Experimental studies on metal-support interactions that are pertinent to electrocatalysis will be discussed. Platinum supported on carbon black is one of the most active electrocatalysts for oxygen reduction in phosphoric acid fuel cells. In the acid environment at 100 to 200/sup 0/C, the Pt surface area decreases with time due to the growth of the supported Pt particles. The effects of a liquid-phase environment on the particle growth mechanism of supported Pt catalysts is discussed. 60 references.

    2015-01-01

    Compared to humans and other mammals, rodent genomes, specifically Muroidea species, underwent intense chromosome reshuffling in which many complex structural rearrangements occurred. This fact makes them preferential animal models for studying the process of karyotype evolution. Here, we present the first combined chromosome comparative maps between 2 Cricetidae species, Cricetus cricetus and Peromyscus eremicus, and the index species Mus musculus and Rattus norvegicus. Comparative chromosome painting was done using mouse and rat paint probes together with in silico analysis from the Ensembl genome browser database. Hereby, evolutionary events (inter- and intrachromosomal rearrangements) that occurred in C. cricetus and P. eremicus since the putative ancestral Muroidea genome could be inferred, and evolutionary breakpoint regions could be detected. A colocalization of constitutive heterochromatin and evolutionary breakpoint regions in each genome was observed. Our results suggest the involvement of constitutive heterochromatin in karyotype restructuring of these species, despite the different levels of conservation of the C. cricetus (derivative) and P. eremicus (conserved) genomes.

  17. A customized head and neck support system

    International Nuclear Information System (INIS)

    Purpose: To describe a customized head and neck immobilization system for patients receiving radiotherapy including a head support that conforms to the posterior contour of the head and neck. Methods: The system includes a customized headrest to support the posterior head and neck. This is fixed to a thermoplastic face mask that molds to the anterior head/face contours. The shape of these customized head and neck supports were compared to 'standard' supports. Results: This system is comfortable for the patients and appears to be effective in reproducing the setup of the treatment. Conclusions: The variability in the size and shape of the customized posterior supports exceeded that of 'standard' headrests. It is our clinical impression that the customized supports improve reproducibility and are now a standard part of our immobilization system. The quantitative analysis of the customized headrests and some commonly used 'standard' headrests suggests that the customized supports are better able to address variabilities in patient shape

  18. Support for heat exchangers

    International Nuclear Information System (INIS)

    The very large heat exchangers which are typical of many nuclear power plants place great demands on their supports. The support here described is for a vertical heat exchanger. A convex Lubrit plate allows a certain amount of transverse and rotational movement of the heat exhanger relative to the foundation. Taps engaging in the support surface of the heat exchanger and between the support box and the concrete foundation ensure that relative movement is restricted to those surfaces where it is intended. A steel box structure embedded in the concrete foundation dissipates heat transferred through the support system and avoids overheating the concrete. Horizontal stays support the heat exchanger against the concrete walls. (JIW)

    The U.S. Geological Survey Earth Resources Observation Systems Data Center responds to emergencies in support of various government agencies for human-induced and natural disasters. This response consists of satellite tasking and acquisitions, satellite image registrations, disaster-extent maps analysis and creation, base image provision and support, Web-based mapping services for product delivery, and predisaster and postdisaster data archiving. The emergency response staff are on call 24 hours a day, 7 days a week, and have access to many commercial and government satellite and aerial photography tasking authorities. They have access to value-added data processing and photographic laboratory services for off-hour emergency requests. They work with various Federal agencies for preparedness planning, which includes providing base imagery. These data may include digital elevation models, hydrographic models, base satellite images, vector data layers such as roads, aerial photographs, and other predisaster data. These layers are incorporated into a Web-based browser and data delivery service that is accessible either to the general public or to select customers. As usage declines, the data are moved to a postdisaster nearline archive that is still accessible, but not in real time.

  12. Comparative Habitability of Transiting Exoplanets

    CERN Document Server

    Barnes, Rory; Evans, Nicole

    2015-01-01

    Exoplanet habitability is traditionally assessed by comparing a planet's semi-major axis to the location of its host star's "habitable zone," the shell around a star for which Earth-like planets can possess liquid surface water. The Kepler space telescope has discovered numerous planet candidates near the habitable zone, and many more are expected from missions such as K2, TESS and PLATO. These candidates often require significant follow-up observations for validation, so prioritizing planets for habitability from transit data has become an important aspect of the search for life in the universe. We propose a method to compare transiting planets for their potential to support life based on transit data, stellar properties and previously reported limits on planetary emitted flux. For a planet in radiative equilibrium, the emitted flux increases with eccentricity, but decreases with albedo. As these parameters are often unconstrained, there is an "eccentricity-albedo degeneracy" for the habitability of transiti...

These composed of four fields such as neutron beam utilization, materials/nuclear materials irradiation test, neutron activation analysis and radioisotope production. In each field, the numbers of project were 17, 7, 4 and 3 respectively. At first, from a selected project of view, supporting ratio by external manpower was reached to the 58%, that is, 18 out of 31 project was supported. In each field, it was 82% for neutron beam utilization and 100% for neutron activation analysis. Also, from the utilization time point of view, supporting ratio of external manpower was reached to 30% for neutron beam utilization and 59% for neutron activation analysis. Otherwise, supporting ratio by manpower in KAERI was reached to 97%, that is, 30 out of 31 project was supported. Also, from the utilization time point of view, total supporting ratio was reached to 15%. In each field, it was 20% for neutron beam utilization, 18% for materials/nuclear materials irradiation test, 20% for neutron activation analysis and 6% for radioisotope production. In order to contribute finding and cultivating of HANARO potential user and increase utilization ratio of HANARO experimental facility, practice-oriented HANARO user education has been done.

  18. Support for Systematic Code Reviews with the SCRUB Tool

    Science.gov (United States)

    Holzmann, Gerald J.

    2010-01-01

    SCRUB is a code review tool that supports both large, team-based software development efforts (e.g., for mission software) as well as individual tasks. The tool was developed at JPL to support a new, streamlined code review process that combines human-generated review reports with program-generated review reports from a customizable range of state-of-the-art source code analyzers. The leading commercial tools include Codesonar, Coverity, and Klocwork, each of which can achieve a reasonably low rate of false-positives in the warnings that they generate. The time required to analyze code with these tools can vary greatly. In each case, however, the tools produce results that would be difficult to realize with human code inspections alone. There is little overlap in the results produced by the different analyzers, and each analyzer used generally increases the effectiveness of the overall effort. The SCRUB tool allows all reports to be accessed through a single, uniform interface (see figure) that facilitates brows ing code and reports. Improvements over existing software include significant simplification, and leveraging of a range of commercial, static source code analyzers in a single, uniform framework. The tool runs as a small stand-alone application, avoiding the security problems related to tools based on Web browsers. A developer or reviewer, for instance, must have already obtained access rights to a code base before that code can be browsed and reviewed with the SCRUB tool. The tool cannot open any files or folders to which the user does not already have access. This means that the tool does not need to enforce or administer any additional security policies. The analysis results presented through the SCRUB tool s user interface are always computed off-line, given that, especially for larger projects, this computation can take longer than appropriate for interactive tool use. The recommended code review process that is supported by the SCRUB tool consists of

    Full Text Available By passing the law on state support in agriculture, fishery and forestry the former support system has been changed. Fishery support beneficiaries can use several kinds of support and help. Former financial stimulations for fishery regulated by law from 1995 to 1st January 2003 were settled by the production stimulation model. Besides that well received model, there are the capital investment model, the support in production insurance, the right to use blue diesel, and granting credit for production of freshwater and saltwater fry, adult fish and shells. These five models of support and help can be used by freshwater and saltwater fish and shell breeders, while for fishing the marine fish the production stimulation model is applied (fishing of small pelagic fish, as well as the capital investment model and right to use blue diesel. Marine and freshwater processors can use the production stimulation and the capital investment model. All these models have in common the fact that all physical and legal entities registered for fishing activities (having licence for commercial fishery, aquaculture (the licence for aquaculture or the one for fish and other marine organisam breeding and processing (having the regulated veterinarian and sanitary conditions, the registration document and having been registered in the List of approved facilities have the right to use them.

    Objective To summarize the construction,upgrading process and clinical application of prostate cancer database (PC-Follow).Methods From September 2008 to December 2014,we designed two versions of off-line PC-Follow clinical databases based on Microsoft Access to support clinical follow-up and research in prostate cancer patients.Then,in order to achieve unified management of clinical data import and multi-center clinical research,we further upgraded PC-Follow to a browser/server (B/S) schema based web database.After upgrade,a simulated multi-center operation pattern was adopted to transfer all existed data-We then attempted to linkage our database with the hospital information system (HIS) and had eventually undertaken reality and stress testing on 3,124 cases'data migration in the hospital.The nationwide software testing and personnel training was conducted in 12 major medical centers.Results Twice of upgrade and alteration of schema of PC-Follow preserved the original user interface.Multiple functions,including data import,follow-up,research support,were obviously enhanced.Notably,the perfection in multi-user and hierarchical access control meet the future needs for multi-center clinical research.Via the import tool for PC-follow V3.0,we successfully migrated all data from the original one.After linking our database with the HIS software by one-way transmission protocol,the safety data extracting could be achieved.Specified administrators were appointed to process and analyze PC-Follow data in bulk,and data were voluntarily shared between attending centers,and showed stable performance on the 3,124 patients in our database.Feedback from nationwide multicenter training and testing indicated that our database was easy,readily accessible,with functionally stable modules,accurate website displays,and ideal response time.Conclusions The online PC-Follow database with hierarchical access provides support for multi-center clinical research in prostate cancer.The off

  12. Three-dimensional elasticity solution of simple-supported rectangular plate on point supports, line supports and elastic foundation

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    This paper studies the bending of simple-supported rectangular plate on point supports, line supports and elastic foundation. On the basis of three-dimensional elasticity theory, the exact expressions of the displacement functions, which satisfy the governing differential equations and the simply supported boundary conditions at four edges of the plate, are analytically derived. The reaction forces of the in- termediate supports are regarded as the unknown external forces acting on the lower surface of the plate. The unknown coefficients are then determined by the boundary conditions on the upper and lower surfaces of the plate. Comparing the numerical results obtained from the proposed method to those obtained from Kirchhoff plate theory, Mindlin plate theory and those obtained from the commer- cial finite element software ANSYS, the high accuracy of the present method has been demonstrated.

  13. Social support, oxytocin, and PTSD

    Directory of Open Access Journals (Sweden)

    Miranda Olff

    2014-12-01

    Full Text Available Background: A lack of social support and recognition by the environment is one of the most consistent risk factors for posttraumatic stress disorder (PTSD, and PTSD patients will recover faster with proper social support. The oxytocin system has been proposed to underlie beneficial effects of social support as it is implicated in both social bonding behavior and reducing stress responsivity, notably amygdala reactivity (Koch et al., 2014; Olff et al., 2010; Olff, 2012. The amygdala is found to be hypersensitive in people with PTSD. Method: In order to investigate neurobiological mechanisms underlying potential preventive and therapeutic effects of intranasal oxytocin, we performed a series of fMRI studies (funded with a prestigious NWO TOP grant: BONDS standing for “Boosting Oxytocin after trauma: Neurobiology and the Development of Stress-related psychopathology” in acutely traumatized persons admitted to the emergency department (Frijling et al., 2014; BOOSTER “Boosting oxytocin after trauma: the effects of intranasal oxytocin administration on emotional and motivational processing and neural activity in PTSD” in police officers with and without PTSD. Results: In this presentation, we present the BOOSTER results on the effects of a single oxytocin administration on amygdala reactivity in response to emotional faces in PTSD patients versus traumatized controls. We found significantly decreased bilateral amygdala reactivity towards emotional faces in PTSD patients compared to traumatized controls. Conclusions: These promising results call for intervention studies such as studying the effects of medication (oxytocin enhanced psychotherapy in PTSD patients.

  14. Postcolonialism And Comparative Education

    Science.gov (United States)

    Tikly, Leon

    1999-11-01

    The article considers the relevance of recent developments in postcolonial theory for comparative education research. The article starts with an account of these developments. This account is then used as a basis for a critical discussion of previous theoretical frameworks that have been used by comparative researchers to explain the colonial legacy. The implications of adopting a postcolonial approach in comparative education are discussed in relation to issues of race, culture, language and the curriculum. The article concludes by arguing that a consideration of the postcolonial condition is necessary for developing a more holistic and less eurocentric understanding of the relationship between globalisation and education.

    Groupware is a term describing an emerging computer software technology enhancing the ability of people to work together as a group, (a software driven 'group support system'). This project originated at the beginning of 1992 and reports were issued describing the activity through May 1995. These reports stressed the need for process as well as technology. That is, while the technology represented a computer assisted method for groups to work together, the Group Support System (GSS) technology als required an understanding of the facilitation process electronic meetings demand. Even people trained in traditional facilitation techniques did not necessarily aimlessly adopt groupware techniques. The latest phase of this activity attempted to (1) improve the facilitation process by developing training support for a portable groupware computer system, and (2) to explore settings and uses for the portable groupware system using different software, such as Lotus Notes.

    2008-01-01

    Mitome is a specialized mitochondrial genome database designed for easy comparative analysis of various features of metazoan mitochondrial genomes such as base frequency, A+T skew, codon usage and gene arrangement pattern. A particular function of the database is the automatic reconstruction of phylogenetic relationships among metazoans selected by a user from a taxonomic tree menu based on nucleotide sequences, amino acid sequences or gene arrangement patterns. Mitome also enables us (i) to easily find the taxonomic positions of organisms of which complete mitochondrial genome sequences are publicly available; (ii) to acquire various metazoan mitochondrial genome characteristics through a graphical genome browser; (iii) to search for homology patterns in mitochondrial gene arrangements; (iv) to download nucleotide or amino acid sequences not only of an entire mitochondrial genome but also of each component; and (v) to find interesting references easily through links with PubMed. In order to provide users with a dynamic, responsive, interactive and faster web database, Mitome is constructed using two recently highlighted techniques, Ajax (Asynchronous JavaScript and XML) and Web Services. Mitome has the potential to become very useful in the fields of molecular phylogenetics and evolution and comparative organelle genomics. The database is available at: http://www.mitome.info.

  8. A Web-Based Decision Support System for Assessing Regional Water-Quality Conditions and Management Actions

    Science.gov (United States)

    Booth, N. L.; Everman, E.; Kuo, I.; Sprague, L.; Murphy, L.

    2011-12-01

    A new web-based decision support system has been developed as part of the U.S. Geological Survey (USGS) National Water Quality Assessment Program's (NAWQA) effort to provide ready access to Spatially Referenced Regressions On Watershed attributes (SPARROW) results of stream water-quality conditions and to offer sophisticated scenario testing capabilities for research and water-quality planning via an intuitive graphical user interface with a map-based display. The SPARROW Decision Support System (DSS) is delivered through a web browser over an Internet connection, making it widely accessible to the public in a format that allows users to easily display water-quality conditions, distribution of nutrient sources, nutrient delivery to downstream waterbodies, and simulations of altered nutrient inputs including atmospheric and agricultural sources. The DSS offers other features for analysis including various background map layers, model output exports, and the ability to save and share prediction scenarios. SPARROW models currently supported by the DSS are based on the modified digital versions of the 1:500,000-scale River Reach File (RF1) and 1:100,000-scale National Hydrography Dataset (medium-resolution, NHDPlus) stream networks. The underlying modeling framework and server infrastructure illustrate innovations in the information technology and geosciences fields for delivering SPARROW model predictions over the web by performing intensive model computations and map visualizations of the predicted conditions within the stream network.

    Abstract The U.S. Geological Survey National Water Quality Assessment Program has completed a number of water-quality prediction models for nitrogen and phosphorus for the conterminous United States as well as for regional areas of the nation. In addition to estimating water-quality conditions at unmonitored streams, the calibrated SPAtially Referenced Regressions On Watershed attributes (SPARROW) models can be used to produce estimates of yield, flow-weighted concentration, or load of constituents in water under various land-use condition, change, or resource management scenarios. A web-based decision support infrastructure has been developed to provide access to SPARROW simulation results on stream water-quality conditions and to offer sophisticated scenario testing capabilities for research and water-quality planning via a graphical user interface with familiar controls. The SPARROW decision support system (DSS) is delivered through a web browser over an Internet connection, making it widely accessible to the public in a format that allows users to easily display water-quality conditions and to describe, test, and share modeled scenarios of future conditions. SPARROW models currently supported by the DSS are based on the modified digital versions of the 1:500,000-scale River Reach File (RF1) and 1:100,000-scale National Hydrography Dataset (medium-resolution, NHDPlus) stream networks.

    The Association of Dental Support Organizations is a recently formed association of 33 companies representing a range of management and support services for dental practices. These organizations do not engage in the practice of dentistry, although in some cases they operate as holding companies for practices that do, thus separating the legal responsibility of providing treatment from the management and flow of funds. This report summarizes some of the recent trends in oral health care and dentists' practice patterns that are prompting the increased prevalence of this model. The general functioning of the DSO model is described, including some common variations, and the core values of ADSO are featured. PMID:26455048

    The present invention is a thin filament embedded in a low density aerogel for use in radiation detection instruments and incandescent lamps. The aerogel provides a supportive matrix that is thermally and electrically nonconductive, mechanically strong, highly porous, gas-permeable, and transparent to ionizing radiation over short distances. A low density, open-cell aerogel is cast around a fine filament or wire, which allows the wire to be positioned with little or no tension and keeps the wire in place in the event of breakage. The aerogel support reduces the stresses on the wire caused by vibrational, gravitational, electrical, and mechanical forces.

    Functions denoted by specific comparative expressions called generalised comparative determiners are analysed. These expressions form verb arguments when applied to common nouns. They denote functions which take sets and a binary relation as argument and give a set as result. These functions are thus different from denotations of "ordinary" determiners. However, they do obey some similar constraints, properly generalised. It is shown that verbal arguments obtained from such generalised determin...

  19. Cascade Support Vector Machines with Dimensionality Reduction

    Directory of Open Access Journals (Sweden)

    Oliver Kramer

    2015-01-01

    Full Text Available Cascade support vector machines have been introduced as extension of classic support vector machines that allow a fast training on large data sets. In this work, we combine cascade support vector machines with dimensionality reduction based preprocessing. The cascade principle allows fast learning based on the division of the training set into subsets and the union of cascade learning results based on support vectors in each cascade level. The combination with dimensionality reduction as preprocessing results in a significant speedup, often without loss of classifier accuracies, while considering the high-dimensional pendants of the low-dimensional support vectors in each new cascade level. We analyze and compare various instantiations of dimensionality reduction preprocessing and cascade SVMs with principal component analysis, locally linear embedding, and isometric mapping. The experimental analysis on various artificial and real-world benchmark problems includes various cascade specific parameters like intermediate training set sizes and dimensionalities.

    An innovative and visually appealing tool is presented for efficient all-vs-all conjunction analysis on a large catalogue of objects. The conjunction detection uses a nearest neighbour search algorithm, based on spatial binning and identification of pairs of objects in adjacent bins. This results in the fastest all vs all filtering the authors are aware of. The tool is constructed on a server-client architecture, where the server broadcasts to the client the conjunction data and ephemerides, while the client supports the user interface through a modern browser, without plug-in. In order to make the tool flexible and maintainable, Java software technologies were used on the server side, including Spring, Camel, ActiveMQ and CometD. The user interface and visualisation are based on the latest web technologies: HTML5, WebGL, THREE.js. Importance has been given on the ergonomics and visual appeal of the software. In fact certain design concepts have been borrowed from the gaming industry.

    Full Text Available Abstract Background First generation Internet technologies such as mailing lists or newsgroups afforded unprecedented levels of information exchange within a variety of interest groups, including those who seek health information. With emergence of the World Wide Web many communication applications were ported to web browsers. One of the driving factors in this phenomenon has been the exchange of experiential or anecdotal knowledge that patients share online, and there is emerging evidence that participation in these forums may be having an impact on people's health decision making. Theoretical frameworks supporting this form of information seeking and learning have yet to be proposed. Results In this article, we propose an adaptation of Kolb's experiential learning theory to begin to formulate an experiential health information processing model that may contribute to our understanding of online health information seeking behaviour in this context. Conclusion An experiential health information processing model is proposed that can be used as a research framework. Future research directions include investigating the utility of this model in the online health information seeking context, studying the impact of collaborating in these online environments on patient decision making and on health outcomes are provided.

    Darwin's claim ‘that the difference in mind between man and the higher animals … is certainly one of degree and not of kind’ is at the core of the comparative study of cognition. Recent research provides unprecedented support for Darwin's claim as well as new reasons to question it, stimulating new theories of human cognitive uniqueness. This article compares and evaluates approaches to such theories. Some prominent theories propose sweeping domain-general characterizations of the difference ...
