Catheter tip dislocation is the main complication of permanent pacemaker implantation using the subclavian vein. In this study of 50 patients we compared the incidence of complications using two endocardial electrodes specially designed to prevent tip dislocation. One catheter had a helical endocardial electrode and the other had retractable nylon barbs. The helical electrode was superior in ev...
This paper details the development and application of the RDS-SUMO-CEASIOM-EDGE rapid-CFD tool. It uses the RDS CAD model as geometry for automated meshing and CFD analysis to produce an aero-data base for control and stability analysis. It is applied to two non-conventional design proposals, an asymmetric twin-prop aircraft and an airliner with rear Open Rotor propulsion, retractable canard, a...
All known algorithms for the Fréchet distance between curves proceed in two steps: first, they construct an efficient oracle for the decision version; second, they use this oracle to find the optimum from a finite set of critical values. We present a novel approach that avoids the detour through the decision version. This gives the first quadratic time algorithm for the Fréchet distance between...
background: current development of surgery is due to medical practitioners and surgeons practices and experiments throughout the history. albucasis, the muslim spanish physician in 10 century ad was one of the pioneers in surgery that had major influence by his innovations in surgical techniques, treatment approaches and invention of instruments. he introduced a type of surgical knife named mok...
Purpose. For accurate resection of nonpalpable malignant breast lesions with a tumor-free resection rim, an exact and stable wire localization is essential. We tested the resistance towards traction force of different localization devices used in our clinic for breast lesions in two types of tissue. Materials and Methods. Eight different commercially available hook-wire devices were examined fo...
