Endophytic fungi of Cassia fistula L.
Endophytic fungi from Cassia fistula or golden shower, a well known medicinal plant in Thailand and Asia, were isolated from trees growing in three geographical separate sites. These locations were Kanchanaburi, Nakhon Ratchasima and Bangkok and were selected to allow comparisons between their endophytic assemblages and to evaluate these data in relation to differences in plant diversity and density and local environment. Kanchanaburi which was the site closest to a natural forest situation provided the highest number of isolates with Bangkok, where the trees were isolated individuals, having the least. Members of the Xylariaceae proved to be common and frequent isolates especially species of Xylaria and Daldinia but Nemania and Hypoxylon were also obtained. Phomopsis was also well represented and clearly was dominant at the Kanchanaburi site. Species of Fusarium, Colletotrichum, Penicillium, Nigrospora, Coprinus and Psathyrella were also identified but were occasional isolates. Differences in endophytic assemblages between samples obtained early in the rainy season (July, 2001) with those sampled towards the end of the rainy season (December, 2001) were found to occur in the Nakhon Ratchasima samples with over twice as many isolates obtained from the December samples. This is likely to be a reflection on the longer exposure period to the potential inoculum of these leaves. A total of 956 endophytic isolates were obtained from the three sites with samples from Kanchanaburi (December 2000) and Bangkok and Nakhon Ratchasima in July 2001 with a further samples from Nakhon Ratchasima in December, 2001. Isolations were also made from different anatomical regions of the leaf, leaf lamina, midrib and veins. There were no appreciable differences in either the number of isolates obtained or an association between leaf area and specific fungal species. Identification of many xylariaceous endophytic isolates is well known to be problematic since Xylaria species rarely produce their anamorphic form in culture and virtually no members of the Xylariaceae develop their teleomorph in culture. Therefore molecular techniques were used to compare DNA sequences of the ITS region from a selection of endophyes with sequences obtained from teleomorphic material, or cultures derived from teleomorphs of identified and authenticated Xylariaceae. Comparisons were also made with data held in GenBank. This enabled the identity of a number of taxa to be made although more sequences from Xylaria species are required for future investigations. A number of non-xylariaceous taxa were also named as a result of DNA sequence comparisons. Secondary metabolites from the xylariaceae were also investigated and their metabolite profiles used to support identifications. The metabolite profiles proved to be a useful tool to confirm doubtful endophytic isolates when their DNA sequences could not place them with certainty in a right group. Together with extracts from other endophytic species, their inhibitory effects on bacteria and fungi were tested. Cassia endophytes were found to show low antimicrobial activity. However, they may later be shown to have other activities when when tested e. g. anti-malarial, anti-cancer and anti-HIV
Visualisation of Linked Data – Reprise
Linked Data promises to serve as a disruptor of traditional approaches to data management and use, promoting the push from the traditional Web of documents to a Web of data. The ability for data consumers to adopt a follow your nose approach, traversing links defined within a dataset or across independently-curated datasets, is an essential feature of this new Web of Data, enabling richer knowledge retrieval thanks to synthesis across multiple sources of, and views on, inter-related datasets. But for the Web of Data to be successful, we must design novel ways of interacting with the corresponding very large amounts of complex, interlinked, multi-dimensional data throughout its management cycle. The design of user interfaces for Linked Data, and more specifically interfaces that represent the data visually, play a central role in this respect. Contributions to this special issue on Linked Data visualisation investigate different approaches to harnessing visualisation as a tool for exploratory discovery and basic-to-advanced analysis. The papers in this volume illustrate the design and construction of intuitive means for end-users to obtain new insight and gather more knowledge, as they follow links defined across datasets over the Web of Data

Guidance in the human–machine analytics process
In this paper, we list the goals for and the pros and cons of guidance, and we discuss the role that it can play not only in key low-level visualization tasks but also the more sophisticated model-generation tasks of visual analytics. Recent advances in artificial intelligence, particularly in machine learning, have led to high hopes regarding the possibilities of using automatic techniques to perform some of the tasks that are currently done manually using visualization by data analysts. However, visual analytics remains a complex activity, combining many different subtasks. Some of these tasks are relatively low-level, and it is clear how automation could play a role—for example, classification and clustering of data. Other tasks are much more abstract and require significant human creativity, for example, linking insights gleaned from a variety of disparate and heterogeneous data artifacts to build support for decision making. In this paper, we outline the potential applications of guidance, as well as the inputs to guidance. We discuss challenges in implementing guidance, including the inputs to guidance systems and how to provide guidance to users. We propose potential methods for evaluating the quality of guidance at different phases in the analytic process and introduce the potential negative effects of guidance as a source of bias in analytic decision making

Using Propositional Logic for Requirements Verification of Service Workflow
This paper presents a requirement-oriented automated framework for formal verification of service workflows. It is based on our previous work describing the requirement-oriented service workflow specification language called SWSpec. This language has been developed to facilitate workflow composer as well as arbitrary services willing to participate in a workflow to formally and uniformly impose their own requirements. As such, SWSpec provides a formal way to regulate and control workflows. The key component of the to-be-proposed framework centers on verification algorithms that rely on propositional logic. We demonstrate that logic-based workflow verification can be applied to SWSpec which is capable of checking compliance and also detecting conflicts of the imposed requirements. By automating compliance checking process, this framework will support scalable services interoperation in the form of workflows in opened environments. © 2005-2012 IEEE
