Major ozonated autohemotherapy is classically used in treating ischemic disorder of the lower limbs. In the present study, we performed major ozonated autohemotherapy treatment in patients with acute cerebral infarction, and assessed outcomes according to the U.S. National Institutes of Health Stroke Score, Modified Rankin Scale, and transcranial magnetic(More)
A matched case-control study was conducted in Beijing to identify the relative importance of major environmental risk factors for outbreaks of hand, foot, and mouth disease (HFMD). A case was defined as a kindergarten class with at least 1 HFMD outbreak. As a control, a kindergarten class that did not experience an HFMD outbreak was used. To identify(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)
BACKGROUND Over the last decade, increases in the number of outbreaks of hand, foot and mouth disease (HFMD) have shifted the disease into the public health spotlight in China. Children under the age of five years are particularly susceptible, with fatalities recorded. However, estimating the burden of HFMD has been difficult to conduct to date. METHODS(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)
The interaction between cuprous oxide (Cu2O) nanocubes and bovine serum albumin (BSA) was investigated from a spectroscopic angle under simulative physiological conditions. Under pH 7.4, Cu2O could effectively quench the intrinsic fluorescence of BSA via static quenching. The apparent binding constant (K A) was 3.23, 1.91, and 1.20 × 104 M-1 at 298, 304,(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)
INTRODUCTION This study was conducted to determine the prevalence of serotypes, virulence factors, and antimicrobial resistance patterns of Shigella spp. in Beijing, China, from 2004 to 2011. METHODOLOGY Real-time PCR assays were used to detect virulent genes, and the Kirby-Bauer disk diffusion method was used to evaluate antimicrobial resistance. (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)
