A CONTENT ANALYSIS OF SPORTS ANALYTICS RESISTANCE
The use of sports analytics has provided fans with a new experience while leading a revolution for sports organizations and teams. Even though it is clear that sports analytics can be beneficial, a massive resistance to sports analytics has been reported from coaches and managers in sports teams or organizations. The purpose of this paper is to find the nature of resistance to sports analytics in professional sports organizations. This study employs a content analysis of magazines and newspapers covering professional sports and business analytics. The views and remarks of coaches and managers on sports analytics are collected and coded to find out the nature of resistance
Microstructured Thin Film Nitinol for a Neurovascular Flow-Diverter
A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac. People found that a flow-diverter based on thin film nitinol (TFN), works very effectively, however there are no studies proving the mechanical safety in irregular, curved blood vessels. Here, we study the mechanical behaviors and structural safety of a novel microstructured TFN membrane through the computational and experimental studies, which establish the fundamental aspects of stretching and bending mechanics of the structure. The result shows a hyper-elastic behavior of the TFN with a negligible strain change up to 180° in bending and over 500% in radial stretching, which is ideal in the use in neurovascular curved arteries. The simulation determines the optimal joint locations between the TFN and stent frame. In vitro experimental test qualitatively demonstrates the mechanical flexibility of the flow-diverter with multi-modal bending. In vivo micro X-ray and histopathology study demonstrate that the TFN can be conformally deployed in the curved blood vessel of a swine model without any significant complications or abnormalities
