We present the results of searches for nucleon decay via n → ¯ νπ 0 and p → ¯ νπ þ using data from a combined 172.8 kt · yr exposure of Super-Kamiokande-I,-II, and-III. We set lower limits on the partial lifetime for each of these modes: τ n→¯ νπ 0 > 1.1 × 10 33 years and τ p→¯ νπ þ > 3.9 × 10 32 years at a 90% confidence level.
A search for the relic neutrinos from all past core-collapse supernovae was conducted using 1496 days of data from the Super-Kamiokande detector. This analysis looked for electron-type anti-neutrinos that had produced a positron with an energy greater than 18 MeV. In the absence of a signal, 90% C.L. upper limits on the total flux were set for several(More)

In this paper, we give a status report of a real-world application scenario that uses two distinct types of workflow within the Triana problem solving environment: serial scientific workflow for the data processing of gravitational waves signals; and the distributed workflows that dynamically map to the virtual Grid overlay of Triana services. We briefly(More)
Service composition refers to the aggregation of services to build complex applications to achieve client requirements. It is an important challenge to make it possible for users to construct complex workflows transparently and thereby insulating them from the complexity of interacting with numerous heterogeneous services. We present an extension to the(More)
In this paper, we describe the graphical abstractions for Grids and services that have been implemented within the Triana problem solving environment. We provide an overview of the ways in which Triana interacts with services (e.g., Web and P2P services) and then how we interact with core Grid components, such as resource managers and data management(More)
