    Design for Portability of Reconfigurable Virtual Instrumentation

    No full text
    A portable architectural design strategy is described for the implementation of reconfigurable virtual instrumentation based on programmable Systems-on-Chip integrating microprocessors and FPGA in the same physical device. The key role is played by a general purpose communication block as a means to efficiently separate the activities carried out in the microprocessor and in the FPGA. Both parts interact according to simple logic protocols by reading and writing data on the common memory resources of the communication block. The architecture of the proposed communication system can be easily implemented in practically any modern programmable System-on-Chip. With the proposed strategy, the porting of embedded software programs and associated FPGA designs among different device families and vendors is facilitated. A structured methodology is proposed for handling complex real-time systems based on these programmable Systems-on-Chip. We described a concrete communication block that has been successfully implemented and utilized for a quick implementation of a data acquisition system based on a Xilinx Zynq-7030 FPGA Mezzanine Card (FMC) and a custom FMC module with an 8-bit 500 MSPS ADC

    DAQ platform based on SoC-FPGA for high resolution time stamping in cosmic ray detection

    No full text
    Accurate timing in cosmic ray detection is critical for reconstruction of events from multiple scattered detectors. Since most of the detectors dedicated to study cosmic rays generate continuous analog signals, a precise timing depends on the sampling rate and the subsequent triggering system operating on the generated digital data stream. In this paper, a data acquisition platform based on a fully programmable System-On-Chip (SoC) and a high-speed analog to digital converter, able to manage 8-bit data resolution, 500MHz sampling rate and GPS connection for data synchronization is presented. The SoC is a ZYNQ 7000 device with a Field Programmable Gate Array (FPGA) and a dual core ARM processor embedded on a single chip. The system achieves 2 ns time resolution and is also able to increase data amplitude resolution through oversampling and can simultaneously generate a real time histogram of the incoming data. The platform has an embedded high voltage power supply control with temperature and pressure compensation for optimal and stable operation of different detectors. While the time critical activities are handled and carried out by the FPGA, software running on the dual core ARM processor with a real time operating system (FreeRTOS) provides Ethernet connection for remote control of the platform

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Expanding “Communities and Collections” in the K-State Research Exchange (K-REx) to benefit the K-State Community and Beyond

    No full text
    Kansas State University has used its institutional repository, the K-State Research Exchange (K-REx), to store and share its first year experience program, K-State First, and notably its common reading program, K-State First Book. We have done so with the aim that the accessibility and preservation of these documents ensures program stability, promotes engagement with first year programming, and provides the ability to foster growth,educational opportunities, and community building outside of K-State. Moving away from research concentrated repositories and taking a more holistic approach to scholarship, especially when realizing the pedagogical significance of collaborative campus programming, institutions can showcase, discover, preserve, and grow programs that shape campus communities and engagement. This session will provide an overview of K-REx and spotlight the digital archive of the university’s first year experience program and common reading program, K-State First Book. We will discuss the benefits and challenges to expanding the purview of your repositories. We talkthrough the types of materials we decide to host in our repository and why we share what we do. We will also provide recommendations on new ways to evaluate what belongs in institutional repositories and how this diversity can benefit your program, your institution, the community, and others

    Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution

    No full text
    Non-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
