Despite the popularity of Java, problems may arise from potential data-race conditionsduring execution of a Java program. Data-races are considered errors in concurrent pro-gramming languages and greatly complicate both programming and runtime optimizationefforts. A race-free version of Java is therefore…

Speculative multithreading (SpMT), also known as thread level speculation (TLS), is a dynamic parallelization technique that relies on out-of-order execution, dependence buffering, and misspeculation rollback to achieve speedup of sequential programs on multiprocessors. A large number of hardware studies have…

Numerous techniques mine change data captured in software archives to assist software engineering efforts. These change-based approaches typically analyze change sets -- groups of co-committed changes -- under the assumption that the development work represented by change sets is both…

High-sulfidation epithermal deposits are genetically associated with calc-alkaline volcanism in subduction zones, and although these ore deposits are excellent places to focus research, subduction zone stratovolcanoes provide important windows on magmatic-hydrothermal processes that are not available from study of the…
