Phenomenal improvements in the computational performance of multiprocessors have not been matched by comparable gains in I/O system performance. This imbalance has resulted in I/O becoming a significant bottleneck for many scientific applications. One key to overcoming this bottleneck is improving the performance of parallel file systems. The design of a high-performance parallel file system re...

Digital Interactive Storytelling (DIS) is a relatively novel area of computer entertainment which aims at investigating interactive applications capable of generating consistent, emergent and rich stories. To provide new solutions for DIS, we have proposed a novel multi-agent DIS framework, DIEGESIS, which includes agents' coordination and new planning and replanning solutions for DIS. A natura...

It is becoming increasingly clear that post-merger and acquisition (M&A) performance, especially in terms of achieving the integration of merging firms, is strongly affected by organizational factors, such as leadership. This paper presents a theoretical model showing how alternative forms of charismatic leadership can be relevant to the implementation of M&As. A unique aspect of our conceptual...

AIMS The aim of this study was to determine whether clopidogrel plus aspirin provides greater protection against major cardiovascular events than aspirin alone in patients with peripheral arterial disease (PAD). METHODS AND RESULTS This is a post hoc analysis of the 3096 patients with symptomatic (2838) or asymptomatic (258) PAD from the CHARISMA trial. The rate of cardiovascular death, myoca...
