Involving the Ricci curvature and the squared mean curvature, we obtain basic inequalities for different kind of submaniforlds of a Sasakian space form tangent to the structure vector field of the ambient manifold. Contrary to already known results, we find a different necessary and sufficient condition for the equality for Ricci curvature of C-totally real submanifolds of a Sasakian space form...

Monitoring spinal curvature in adolescent kyphoscoliosis requires regular radiographic examinations; however, the applied ionizing radiation increases the risk of cancer. Ultrasound imaging is favorable over X-ray because it does not emit ionizing radiation. It has been shown in the past that tracked ultrasound can be used to localize vertebral transverse processes as landmarks along the spine ...

ARTICLE INFO ______________________________________________________________ ______________________ Introduction: The study was aimed to assess the presence of actual differences between the objective and the perceived magnitude of a curvature between patients affected by Peyronie’s disease (PD) and congenital penile curvature (CPC). Materials and Methods: Wee analysed a cohort of 88 consecutive...

Most ground target tracking problems involve nonlinear filtering due to nonlinearity in the measurement model. At present, a quantitative measure of nonlinearity and its relationship with the performance of the filtering algorithms are lacking. We quantify the degree of nonlinearity of a filtering problem using the differential geometry based measures of nonlinearity such as the parameter-effec...
