As a core step in clustering analysis, distance measurement results can influence accuracy. Existing methods are mostly based on cluster feature information. However, these features may be insufficient and result losing data information for clusters containing number of objects. To improve accuracy, we make full use the distribution characteristics objects clusters, i.e., descriptive statistics...

BACKGROUND The stability of mammalian serum and urine in large metabolomic investigations is essential for accurate, valid and reproducible studies. The stability of mammalian serum and urine, either processed immediately by freezing at -80 degrees C or stored at 4 degrees C for 24 h before being frozen, was compared in a pilot metabolomic study of samples from 40 separate healthy volunteers. ...

Purpose: The aim of this study is to evaluate effectiveness of regularly used disinfectant solution in the disinfection of acrylic resin specimens contaminated with Candida albicans. Materials and methods: Thirty six acrylic resin specimens contaminated in vitro with 1.5×10 8 cfu/ml suspensions of microorganisms were immersed in disinfectants for 10 minutes, the control group was not submitted ...

In contrast to the multitude of investigations regarding aesthetic changes in nasal surgery, few data are available concerning nasal function. This is especially important for cleft patients with a compromised nasal respiration.In this prospective study, 68 cleft patients, who underwent nasal surgery, were evaluated concerning aesthetic and respiratory outcome. To assess nasal respiration, acti...

For comparing the distribution of two samples with multiple endpoints, O'Brien (1984) proposed rank-sum-type test statistics. Huang et al. (2005) extended these statistics to the general nonparametric Behrens-Fisher hypothesis problem and obtained improved test statistics by replacing the ad hoc variance with the asymptotic variance of the rank-sum statistics. In this paper we generalize the wo...

The problem of sample size determination based on three commonly used non-parametric rank based tests, namely, one-sample Wilcoxon's rank sum test, two-sample's Wilcoxon's rank sum test, and the rank-based test for independence is studied. Explicit formulas for variabilities of the test statistics under the alternative hypotheses are derived. Consequently, close forms of power functions of thes...

INTRODUCTION Receptor activator of nuclear factor kappa B ligand (RANKL) is a key regulator of bone metabolism. Anti-citrullinated protein antibodies (ACPA) have been suggested to cause bone destruction by osteoclast activation. We investigated the relationship between RANKL and ACPA in patients with early untreated rheumatoid arthritis (RA). METHODS Patients with newly diagnosed untreated RA...

OBJECTIVE To test the effectiveness of the FHWA guidelines for intersection design. METHODS In an experimental design we used kinematics measures from an instrumented vehicle and behavioral (error) data collected during on-road evaluations to quantify the effects of improved versus unimproved intersections (turn phase) and to determine if these intersections were safer (vehicular stability an...

BACKGROUND Previous studies have suggested that some children with autosomal recessive polycystic kidney disease (ARPKD) have growth impairment out of proportion to their degree of chronic kidney disease (CKD). The objective of this study was to systematically compare growth parameters in children with ARPKD to those with other congenital causes of CKD in the chronic kidney disease in Children ...
