We isolated several stilbene compounds including rhaponticin (3',5-dihydroxy-4'-methoxystilbene 3- O-beta- D-glucopyranoside) from extracts of rhubarb rhizomes. These compounds showed significant hypoglycemic effects in streptozotocin (STZ)-induced type 1 diabetic rats and mice. In this study, we investigated the effect of rhaponticin on glucose(More)
To solve the invalidation problem of Dempster-Shafer theory of evidence (DS) with high conflict in multi-sensor data fusion, this paper presents a novel combination approach of conflict evidence with different weighting factors using a new probabilistic dissimilarity measure. Firstly, an improved probabilistic transformation function is proposed to map(More)
In this paper, we propose a novel method for fast face recognition called L 1/2-regularized sparse representation using hierarchical feature selection. By employing hierarchical feature selection, we can compress the scale and dimension of global dictionary, which directly contributes to the decrease of computational cost in sparse representation that our(More)
The Glu298Asp polymorphism in the NOS3 gene has been implicated as a risk factor for prostate cancer. To date, several studies have evaluated the associations between the Glu298Asp polymorphism and prostate cancer risk; however, the results were inconclusive. The aim of the current study was to perform a meta-analysis to investigate the association between(More)

Extreme learning machine (ELM) as a neural network algorithm has shown its good performance, such as fast speed, simple structure etc, but also, weak robustness is an unavoidable defect in original ELM for blended data. We present a new machine learning framework called “LARSEN-ELM” for overcoming this problem. In our paper, we would like to show two key(More)
With the keywords of "acupuncture" "acupuncture and moxibustion" "perimenopausal syndrome" "rules of acupoint selection", the clinical literature in recent 10 years regarding perimenopausal syndrome treated with acupuncture and moxibustion was searched from China National Knowledge Infrastructure(CNKI). One hundred and ninety-seven relevant articles were(More)
Background. With the development of massively parallel sequencing (MPS), noninvasive prenatal diagnosis using maternal cell-free DNA is fast becoming the preferred method of fetal chromosomal abnormality detection, due to its inherent high accuracy and low risk. Typically, MPS data is parsed to calculate a risk score, which is used to predict whether a(More)
In Vehicular Cyber-Physical Systems (VCPS), the collected sensor data are always uncertain and conflicting. Dempster-Shafer (DS) evidence theory can effectively deal with uncertain information, but the Dempster's rule may produce counter-intuitive results when the information is conflicting. This paper proposed an improved approach for combining conflicting(More)
