Spaces with radially symmetric curvature at base point p are shown to be diffeomorphic to space forms. Furthermore, they are either isometric to Rn or Sn under a radially symmetric metric, to RPn with Riemannian universal covering of Sn equipped with a radially symmetric metric, or else have constant curvature outside a metric ball of radius equal to the injectivity

The growing competitiveness in the automotive industry and strict standards to which it is subject, require high quality standards. For this, tools such as failure mode effects analysis (FMEA) are applied quantify risk of potential modes. However, for qualitative defects with subjectivity associated uncertainty, lack specialized technicians, revealed inefficiency visual inspection process, well...

We present a spectral sequence which efficiently computes Betti numbers of a closed semi-algebraic subset of RP defined by a system of quadratic inequalities and the image of the homology homomorphism induced by the inclusion of this subset in RPn. We do not restrict ourselves to the term E2 of the spectral sequence and give a simple explicit formula for the differential d2.

In 2008, the Ontario Long Term Care Association was awarded funding from HealthForceOntario to assist with its nursing recruitment strategy based on research it had initiated in 2007. The research goal was to understand the career motivations and perceptions of students enrolled in registered nursing (RN) and registered practical nursing (RPN) programs in Ontario to develop and test a message t...

BACKGROUND Nephron-sparing surgery has become the standard treatment for T1 renal tumors. However, relevant data on the Taiwanese population are lacking, and most of the current literature uses global instead of split renal function (SRF) for postoperative renal function follow-up. We evaluated the postoperative renal function after minimally invasive partial nephrectomy in Taiwanese patients. ...

PURPOSE To report our early experiences with failure mode and effects analysis (FMEA) in a community practice setting. METHODS The FMEA facilitator received extensive training at the AAPM Summer School. Early efforts focused on department education and emphasized the need for process evaluation in the context of high profile radiation therapy accidents. A multidisciplinary team was assembled ...

BACKGROUND Minimally invasive approaches to partial nephrectomy have been rapidly gaining popularity but require advanced laparoscopic surgical skills. Renal hilar tumors, due to their anatomic location, pose additional technical challenges to the operating surgeon. OBJECTIVE We compared the outcomes of robot-assisted partial nephrectomy (RPN) for hilar and nonhilar tumors in our large multic...
