Introduction Perforation of the gallbladder is a benign and common complication during laparoscopic cholecystectomy. However, it may result in stone spilling, which potentially can lead to serious postoperative complications. Case report A 70-year-old male underwent laparoscopic cholecystectomy for acute cholecystitis. The procedure was complicated by perforation of the gallbladder and spilling...

Current trends in CMPs indicate that the core count will increase in the near future. One of the main performance limiters of these forthcoming microarchitectures is the latency and high-demand of the on-chip network and the off-chip memory communication. To optimize the usage of on-chip memory space and reduce off-chip traffic several techniques have proposed to use the N-chance forwarding mec...

Rumen microbes produce cellular protein inefficiently partly because they do not direct all ATP toward growth. They direct some ATP toward maintenance functions, as long-recognized, but they also direct ATP toward reserve carbohydrate synthesis and energy spilling (futile cycles that dissipate heat). Rumen microbes expend ATP by vacillating between (1) accumulation of reserve carbohydrate after...

Many architectures require that a program use pairs of adjacent registers to hold double-precision oating-point values. Register allocators based on Chaitin's graph-coloring technique have trouble with programs that contain both single-register values and values that require adjacent pairs of registers. In particular, Chaitin's algorithm often produces excessive spilling on such programs. This ...

Because of the high volume and unpredictable arrival rates, stream processing systems may not always be able to keep up with the input data streams, resulting in buffer overflow and uncontrolled loss of data. To continuously supply online results, two alternate solutions to tackle this problem of unpredictable failures of such overloaded systems can be identified. One technique, called load she...

Recent research shows that maintaining SSA form allows to split register allocation into separate phases: spilling, register assignment and copy coalescing. After spilling, register assignment can be done in polynomial time, but copy coalescing is NP-complete. In this paper we present an assignment approach with integrated copy coalescing, which maps the problem to the Partitioned Boolean Quadr...
