BACKGROUND The standard diagnostic approach in patients with suspected deep vein thrombosis is to repeat the compression ultrasonography after 1 week in all patients with an initial normal result. We hypothesized that a normal finding of a D-dimer assay safely obviates the need for repeated ultrasonography. In addition, we evaluated the potential value of a pretest probability assessment for th...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

BackgroundMany studies reported that copper, zinc and magnesium play important roles in the pathogenesis and development of neonatal hyperbilirubinemia. Exchange transfusion and intensive phototherapy are known two modalities of therapy for severe neonatal hyper bilirubinemia, but the effect of them on those trace elements is unknown.Materials and MethodsCopper, Zinc and Magnesium serum levels ...

The spatial arrangement of social network data in graphs can influence viewers’ perceptions of structural characteristics such as prominence, bridging and grouping. To study the extent of this effect, we conducted an experiment with 80 graduate students. Each student viewed three of five different spatial arrangements of the same network. We found that viewers' perceptions of structural feature...

BACKGROUND Institutionalization after hip fracture is a socio-economical burden. We examined the predictive value of Instrumental Activities of Daily Living (IADL) and Mini Mental State Examination (MMSE) for institutionalization after hip fracture to identify patients at risk for institutionalization. METHODS Fragility hip fracture patients ≥65 years of age (n = 584) were comprehensively exa...

In this paper, we propose a class of general pretest estimators for the univariate normal mean. The main mathematical idea proposed is adaptation randomized tests, where randomization probability related to shrinkage parameter. Consequently, includes many existing estimators, such as pretest, shrinkage, Bayes, and empirical Bayes special cases. Furthermore, can be easily tuned users by adjustin...

Drawing upon earlier studies of reforms and institutional changes in higher education, the purpose this paper is to trace how understanding accountability has changed over past twenty years it understood have impacted on education institutions. We do so by reviewing more than 350 papers asking three questions: Who answers whom? For what are they answering? And assess those arrangements? With th...
