OBJECTIVE This study aimed to translate and culturally adapt the Falls Risk Awareness Questionnaire (FRAQ) for the elderly Brazilian population as well as to evaluate the internal consistency and reliability of this instrument. METHOD The study used internationally accepted guidelines for the cross-cultural adaptation process. The questionnaire in its final Portuguese version was then applied...

One of the important fields in statistics is testing hypothesis of correlation coefficient. The extension of the idea of testing correlation to fuzzy hypothesis is of great interesting. In this study, we examined the use of fuzzy hypothesis testing approach for the Sequential Probability Ratio Test (SPRT) of correlation coefficient. Use of fuzzy hypothesis testing for correlation coefficient wi...

A method for using gray-scale statistics for the inspection of assemblies is described. A test image of an assembly under inspection is registered with a model image of a nondefective assembly and the two images are corn ared on the basis of two statistical tests: a X 3 test of the two marginal gray-level distributions and the correlation coefficient of the joint distribution. These tests are m...

Serum of multiparous women can contain HLA polyclonal antibodies which can be used as reagents for serological typing of HLA class I and class II. The aim of this study was to investigate an alloimmunization of multiparous women and to identify HLA polyclonal antibodies which could be useful as laboratory reagents in view of the future HLA unit of the Department of Immunology at Abidjan. In an ...

AIM To compare intravoxel incoherent motion (IVIM)-derived parameters with conventional diffusion-weighted imaging (DWI) parameters in predicting the histological grade of hepatocellular carcinoma (HCC) and to evaluate the correlation between the parameters and the histological grades. METHODS A retrospective study was performed. Sixty-two patients with surgically confirmed HCCs underwent dif...

Estimation model between soil moisture content and the near infrared reflectance was established by the linear regression method and the models between soil total nitrogen content and the near infrared reflectance were also established by the BP neural network method and Support Vector Machine (SVM) method. Forty-eight soil samples were collected from China Agricultural University Experimental ...

The purpose of this study was to assess the reliability of critical power (CP) and the total amount of work accomplished above CP (W´) across repeated tests using ecologically valid maximal effort time-trials (TT) under laboratory conditions. After an initial incremental exercise test, ten well-trained male triathletes (age: 28.5 ± 4.7 years; body mass: 73.3 ± 7.9 kg; height: 1.80 ± 0.07 m; max...

conclusions test-retest and correlation analyses have identified non-redundant radiomics features and this feature are prone to errors if they employed as quantitative biomarker for gbm image analysis. however when we use robust and redundant feature, quantitative image radiomics features are informative and prognostic biomarkers for gbm magnetic resonance imaging. results results shows that th...
