Curative resection of pancreatic and biliary malignancies is rare. Most tumors are inoperable at presentation, and palliation of jaundice often is the goal. Biliary decompression can be achieved by surgical diversion or endoscopic biliary stents. This study aimed to compare clinical outcomes between surgical bypass and endoscopic uncovered nitinol stents in(More)
BACKGROUND Pyoderma gangrenosum is a rare inflammatory disease of unknown etiology and a poorly understood pathogenesis. Its clinical presentation is variable and a large percentage of cases are associated with inflammatory bowel diseases. Peristomal pyoderma gangrenosum represents a variant of the diseases, occurring in patients with colostomy. Multiple(More)
Verification techniques and software model checking in particular have gained considerable traction in industry, especially after a number of high-profile success stories tackling specific problems. However, widespread adoption remains distant and, among other causes, one obstacle is the huge number of systems that software model checkers cannot fully(More)
Software Model Checkers have shown outstanding performance improvements in recent times. Moreover, for specific use cases, formal verification techniques have shown to be highly effective, leading to a number of high-profile success stories. However, widespread adoption remains unlikely in the short term and one of the remaining obstacles in that direction(More)
In this paper we present an approach to check resource consumption contracts using an off-the-shelf static analyzer. We propose a set of annotations to support resource usage specifications, in particular, dynamic memory consumption constraints. Since dynamic memory may be recycled by a memory manager, the consumption of this resource is not monotone. The(More)
