BACKGROUND Diagnosing house dust mite (HDM) allergic rhinitis is difficult. The nasal provocation test (NPT) has been shown to be the most pertinent, but several methods are available. According to guidelines, the NPT requires a skin end-point titration and an objective measurement of nasal patency. Hence, NPT is time consuming and its use is limited. (More)
Changes to a composite service need to be well analyzed in order to ensure the trust of it. The analysis can be driven by identifying the impact caused by the changes on the trust of other component services as well as the composite service. In this paper, we propose a trust impact analysis model to analyze the impact of two kinds of evolution operations(More)
We report on the influence of choice of promoter and RNA polymerase, 5′-untranslated regions and ribosome binding sites, codon usage, leader peptide coding sequences and poly A tail in the 3′-untranslated region on the synthesis of porcine somatotropin (PST) in Escherichia coli. A total of 12 different constructs were tested in this study for the production(More)
As an important method for creating value-added services by composing existing services, Web service composition technology has attracted an increasing attention in recent years. Most current service composition and optimization methods utilize quality of service (QoS) attributes to decide which concrete services to invoke. However, trust which is of(More)
Several studies have shown that soil microorganisms play a key role in the success of plant invasion. Thus, ecologists have become increasingly interested in understanding the ecological effects of biological invasion on soil microbial communities given continuing increase in the effects of invasive plants on native ecosystems. This paper aims to provide a(More)
Trust is one of the most critical factors for a service requestor when selecting the best one from a large pool of services. However, existing web service trust models either do not focus on satisfying customer's preference for different quality of service (QoS) attributes, or do not pay enough attention to the impact of malicious ratings on trust(More)
The performance of commercial websites is a critical issue that has a significant effect on consumers’ online decision-making. This study develops and applies a fuzzy model to assess the performance of hotel websites. It presents a fuzzy decision-making approach to the evaluation of tourism website performance that integrates consumer perceptions with a(More)
Composite services implement value-added functionality by composing service components with smaller granularity. Trust is an important criterion to judge whether a composite service can behave as expected. A feasible trust evaluation method for composite services is needed, which can guide service selection for users and the trust-based optimization and(More)
Previous studies on hotel website performance have relied on frequency counting, content analysis or user behavioral approaches [1]. These studies cannot accurately calculate hotel website performance in terms of user assessments of dimension/ attribute weighting and performance ratings. The aim of this research is to develop a scientific model that(More)
