A new concept based on fluorescence lifetime correlation spectroscopy (FLCS) is presented allowing the simultaneous determination of diffusion coefficients of identical molecules located in different environments. The difference in fluorescence lifetimes, which is the main prerequisite for FLCS, is reached by locating one population of the dye close to a light-absorbing surface. Since such surf...
Introduction: Student assessment is of the most important responsibilities of a clinical teacher. Application of new methods of assessment is necessary due to significant improvement in clinical teaching methods. In the meantime, new assessment approaches that simultaneously enforce learning have been greeted more than other methods. Therefore, this study was conducted to compare the new method...
Introduction: Assessment is an essential and integral part of medicine. In addition to validity and reliability, a desirable method for student evaluation should leave a positive effect on student’s learning and be feasible and acceptable by students and teachers. Hence, this study aimed to survey students’ and teachers’ satisfaction with DOPS examination. Methods: This experimental study used...

The fossil record represents the world’s largest historical dataset of biodiversity. However, biomechanical and ecological potential this has been restricted by various unique barriers obstructing experimental study. Fossils are often partial, modified taphonomy, or lacking modern analogs. In past, these confined many studies to descriptive observational techniques. Fortunately, advances in com...
This paper presents techniques for speeding up commonly used algorithms for bounding volume construction using Intel’s SIMD SSE instructions. A case study is presented, which shows that speed-ups between 7–9 can be reached in the computation of k-DOPs. For the computation of tight fitting spheres, a speed-up factor of approximately 4 is obtained. In addition, it is shown how multi-core CPUs can...
Creating an appropriate mesh is one of demanding tasks of many global illumination algorithms. Discontinuity meshing proved to diminish artifacts caused by other meshing strategies. Since naive discontinuity meshing would produce a great amount of geometric computations, accelerating techniques are usually involved. In this paper, we present results obtained with help of k-discrete orientation ...
