Purpose: The purpose of this paper is discriminating between tumor progression and response to treatment based on follow-up multi-parametric magnetic resonance imaging (MRI) data retrieved from glioblastoma multiforme (GBM) patients. Materials and Methods: Multi-parametric MRI data consisting of conventional MRI (cMRI) and advanced MRI [i.e., perfusion weighted MRI (PWI) and diffusion kurtosis ...

The aim of the study is to examine student football players’ perceived risk levels according some variables. Descriptive survey model was used in research. research applied on 240 students playing 1st amateur league, Ordu. ‘Risk Assessment Scale’ developed by Karataş (2012) as a data collection tool. scale scores groups independent variables were compared with t-test, one-way analysis variance ...

We generated exact probability distributions for sample sizes up to 35 in each of three groups ( 105 N  ) and up to 10 in each of four groups ( 40 N  ). We provided a portion of these exact probability tables and compared the exact distributions to the chi-square, gamma, and beta approximations. The beta approximation was best in terms of the root mean squared error. At specific significance ...

Coherent bipolar electric field structures with negative unipolar potentials are widely observed in space plasmas. These often found to be ion Bernstein Greene Kruskal (BGK) modes or holes. Most theoretical models of holes assume them stationary respect the background plasma that follows either Maxwellian kappa-type distribution. In this paper, we present a new model where non-stationary, and e...

The non-normality may occur in the data due to several reasons such as presence of outlier or skewness. It leads lose power and fail control Type I error probability tests which are used test equality group means under heteroscedasticity. To overcome this problem, a revised generalized F-test (RGF) is proposed heteroscedasticity caused by skewness study. An extensive Monte-Carlo simulation stud...

The aim of this retrospective study was to determine whether a virtually created occlusion is as accurate conventionally occlusion. Seventeen orthognathic patients were included in the study, which conducted university clinic. Plaster cast models obtained and digitized. Two experienced observers conventional (gold standard) virtual assess inter-observer variability. One observer second time int...
