The coordination and harmonization of advanced e-Infrastructure project developed with partners from Europe, Latin America, Arabia, Africa, China, and India contributed to developing interoperable platforms based on identity federation and science gateway technologies. This paper presents these technologies to support key services in the development of Arabia networking and services platform for research and education. The platform provides scientists, teachers, and students with seamless access to a variety of advanced resources, services, and applications available at regional e-Infrastructures in Europe and elsewhere. Users simply enter the credentials provided by their home institutions to get authenticated and do not need digital certificate-based mechanisms. Twenty applications from five scientific domains were deployed and integrated. Results showed that on average about 35,000 monthly jobs are running for a total of about 17,500 CPU wall-clock hours. Therefore, seamlessly integrated e-Infrastructures for regional e-Science activities are important resources that support scientists, students, and faculty with computational services and linkage to global research communities. 展开更多

Diabetes is a global public health concern in the 21st century. According to the report in the International Diabetes Federation Diabetes Atlas in 2015, 415 million adults suffer from diabetes globally. Although considerable progress has made in the treatment of diabetes, such as insulin administration, researchers are still looking for alternative therapeutic approaches, e.g. islet transplantation from cadaveric donors, for its radical cure. However, this approach is limited due to the scarcity of donors and availability of islet cells. 展开更多

Digital transformation has been corner stone of business innovation in the last decade, and these innovations have dramatically changed the definition and boundaries of enterprise business applications. Introduction of new products/ services, version management of existing products/ services, management of customer/partner connections, management of multi-channel service delivery (web, social media, web etc.), merger/acquisitions of new businesses and adoption of new innovations/technologies will drive data growth in business applications. These datasets exist in different sharing nothing business applications at different locations and in various forms. So, to make sense of this information and derive insight, it is essential to break the data silos, streamline data retrieval and simplify information access across the entire organization. The information access framework must support just-in-time processing capabilities to bring data from multiple sources, be fast and powerful enough to transform and process huge amounts of data quickly, and be agile enough to accommodate new data sources per user needs. This paper discusses the SAP HANA Smart Data Access data-virtualization technology to enable unified access to heterogenous data across the organization and analysis of huge volume of data in real-time using SAP HANA in-memory platform. 展开更多

This paper suggests an approach for providing the dynamic federations of clouds. The approach is based on risk assessment technology and implements cloud federations without consideration of identity federations. Here, for solving this problem, first of all, important factors which are capable of seriously influencing the information security level of clouds are selected and then hierarchical risk assessment architecture is proposed based on these factors. Then, cloud provider’s risk priority vectors are formed by applying the AHP methodology and fuzzy logic excerpt type risk evaluation is carried out based on this vector. 展开更多

Uterine cervical cancer is the second most common gynecological malignancy.It is estimated that over 35%of tumors are diagnosed at locally advanced disease,stageⅠB2-ⅡB with an estimated 5-year overall survival of 60%.During the last decades,the initial treatment for these women has been debated and largely varies through different countries.Thus,radical concurrent chemoradiation is the standard of care in United Sated and Canada,and neoadjuvant chemotherapy followed by radical surgery is the first line of treatment in some institutions of Europe,Asia and Latin America.Until today,there is no evidence of which strategy is better over the other.This article describe the evidence as well as the advantages and disadvantages of the main strategies of treatment for women affected by uterine cervical cancer stageⅠB2-ⅡB. 展开更多

It has been one of the most hot research topics. Now many corporations have involved in the performance dashboard Architectures related techniques and many performance dashboard Architectures have been put forward. This is a favorable situation to study and application of performance dashboard related techniques. Though interesting, there are also some problems for so many Architectures forms. For to a novice or user with little knowledge about performance dashboard Architectures, it is still very hard to make a reasonable choice. What differences are there for different performance dashboard Architectures and what characteristics and advantages each has? To answer these problems, the characteristics, architectures and applications of several popular performance dashboard Architectures are analyzed and discussed in detail. From the comparison of these Architectures, users can better understand the different performance dashboard Architectures and more reasonably choose what they want. 展开更多

SPARQL endpoints conceptually represent RPC-style, coarse-grained data access mechanisms. Nevertheless, through the potential interlinking of the contained entities, SPARQL endpoints should be able to over distinct advantages over plain Web APIs. To our knowledge, to date, there has been no study conducted that gauges the impact of the link on SPARQL query execution, especially in a federated set-up. In this paper, we investigate how the existence and types of typed links influences the execution characteristics of different SPARQL federation frameworks. In order to measure the query performance, we propose a combined cost model based on a statistic analysis of the query performance metrics that involves parameters such as type of link, the data catalogues and cache, number of links, and number of distinct subjects. As result, we show that number of distinct subject and number of links have significant impact on Federation over SPARQL Endpoints performance whereas type of link does not have significantly influence in federation query performance. 展开更多
