PURPOSE To compare the measurement of the testicular volume of Wistar rats using a caliper and ultrasonography. METHODS Forty Wistar rats were randomly assigned into four groups. A tensile force of 1.6 Newton (N) and 1.0 N was applied to the right spermatic cord in group I and group II, respectively. Group III was the sham group, and group IV served as a control. The initial and final testicu...

The correlation between delta differences for 20 serum chemistry tests was calculated for 2400 samples from 288 patients. There were 12 pairs of chemistry tests for which correlation coefficients of the delta checks exceeded 0.25; aspartate aminotransferase and alanine aminotransferase had the highest Pearson correlation coefficient, 0.915. The highest negative, indirect, correlation was betwee...

OBJECTIVE The objective of our study was to compare calculated prostate volumes derived from tridimensional MR measurements (ellipsoid formula), manual segmentation, and a fully automated segmentation system as validated by actual prostatectomy specimens. MATERIALS AND METHODS Ninety-eight consecutive patients (median age, 60.6 years; median prostate-specific antigen [PSA] value, 6.85 ng/mL) ...

many other biomedical journals dealing with cancer research, often publishes papers whose principal aim it is to test the association between quantative measurements of biological variables. When these are expressed on continuous scales, the statistics most frequently adopted to test their association are the Bravais-Pearson (parametric) and the Spearman (non-parametric) correlation coefficient...

PURPOSE Plasma volume and blood volume are imaging-derived parameters that are often used to evaluation intracranial tumors. Physiologically, these parameters are directly related, but their two different methods of measurements, T1-dynamic contrast enhanced (DCE)- and T2-dynamic susceptibility contrast (DSC)-MR utilize different model assumptions and approaches. This poses the question of whet...

Methods of testing the equality of conditional correlation of bivariate data across a third variable of interest (covariate) have been studied [9, 10, 11, 12, 13, 14, 15, 16]. Most of these methods, such as the test based on Fisher z-transformation [15], the likelihood ratio tests, and the C(α) statistics [9], are limited to the case where a categorical covariate is considered. When the covaria...

Machine translation translates a speech of text from the source language to target language. This paper introduces machine translation evaluation by calculating the semantic textual similarity between the machine translated sentences. The similarity score varies by using different values of alpha, beta and ranges semantic similarity [0,5]. The experiment is carried out on SemEval 2017 datasets....

METHODS: Prospective, longitudinal cohort study conducted between October 2012 and October 2013. Thirty-three eyes from 33 patients (20 females, 13 males; mean age = 73 ± 7 years) were included in the study, and underwent phacoemulsification followed by pseudophakic intraocular lens (IOL) implantation. All patients were evaluated with a high-speed Scheimpflug camera (Corvis ST, Oculus, Wetzlar,...

The perception of the environment is a major issue in autonomous robots. In our previous works, we have proposed a visual perception system based on an automatic image discarding method as a simple solution to improve the performance of a real-time navigation system. In this paper, we take place in the obstacle avoidance context for vehicles in dynamic and unknown environments, and we propose a...
