BACKGROUND The calcium-binding protein S100A12 correlates with measures of disease activity in patients with rheumatoid arthritis (RA). The protein reflects neutrophil activation and the present objective was to explore in a pilot study the associations between S100A12 and other inflammatory markers, clinical assessments as well as degree of synovitis detected by a comprehensive ultrasonography...

We have examined whether the major axes of rich galaxy clusters tend to point toward their nearest neighboring cluster. We have used the data of Ulmer, McMillan, and Kowalski, who used position angles based on X-ray morphology. We also studied a subset of this sample with updated positions and distances from the MX Northern Abell Cluster Survey (for rich clusters (R ≥ 1) with well known redshif...

This paper reports two studies that assessed whether the six factors of assertiveness, bargaining, coalition, friendliness, higher authority, and reasoning best represent the domain of influence tactics in India. Data was collected from 281 graduate business students on their lateral influence tactics and value systems, and from 280 managers on their upward influence tactics, their value system...

BACKGROUND Reductions in vascular surgery reimbursement emphasize the need to decrease cost while maintaining quality. Hospital solvency is essential if we are to preserve acceptable levels of nursing/support personnel and acquire new diagnostic and treatment programs. METHODS Care processes for patients undergoing carotid, aortic, or dialysis access surgery were retrospectively analyzed and ...

Abstract In this work, we collected a sample of BL Lacs and FR I II(G) radio galaxies with available core extended emissions from published works to discuss the unified schemes estimate Doppler factor for Lacs. A Wilcoxon rank-sum test Kolmogorov–Smirnov both suggest that probabilities distribution luminosity being same parent are pWRS = 0.779 pK-S 0.326, suggesting they unified. Based on schem...

Methods We performed a nested case-control analysis with 1:2 matching for 39 cases of paroxysmal AF (n=28, in sinus rhythm during cardiac magnetic resonance (CMR)) and HF (n=14, AF+HF; n=3) and 78 controls with similar demographic and clinical characteristics at the baseline (Table 1). LA circumferential (short axis) and longitudinal strain rate (horizontal long axis) were measured using Multi-...

UnifyPow is a freeware SAS ® macro that performs statistical power analysis and other matters related to sample-size choice. Its functionality covers an extensive set of methods. One-group tests include the t and Wilcoxon for H 0 : μ = μ 0 ; the binomial and Z approximation for H 0 : π = π 0 ; t and Wilcoxon for paired means; McNemar's for paired proportions; and Fishers's r-to-Z for H 0 : ρ = ...

Due to historical legal challenges, there is a driving force for the development of objective methods of forensic toolmark identification. This study utilizes an algorithm to separate matching and nonmatching shear cut toolmarks created using fifty sequentially manufactured pliers. Unlike previously analyzed striated screwdriver marks, shear cut marks contain discontinuous groups of striations,...

In this paper, we propose a support vector machine (SVM) ensemble classification method. Firstly, dataset is preprocessed by Wilcoxon rank sum test to filter irrelevant genes. Then one SVM is trained using the training set, and is tested by the training set itself to get prediction results. Those samples with error prediction result or low confidence are selected to train the second SVM, and al...
