Discovering co-expressed genes and coherent expression patterns in gene expression data is an important data analysis task in bioinformatics research and biomedical applications. Although various clustering methods have been proposed, two tough challenges still remain on how to integrate the users’ domain knowledge and how to handle the high connectivity in the data. Recently, we have systemati...

JUMP-1 is currently under development by seven Japanese universities to establish techniques for building an e cient distributed shared memory on a massively parallel processor. It provides a coherent cache with reduced hierarchical bit-map directory scheme to achieve cost e ective and high performance management. Messages for coherent cache are transferred through a fat tree on the RDT(Recursi...

Spin impurities in diamond can be versatile tools for a wide range of solid-state-based quantum technologies, but finding spin impurities that offer sufficient quality in both photonic and spin properties remains a challenge for this pursuit. The silicon-vacancy center has recently attracted much interest because of its spin-accessible optical transitions and the quality of its optical spectrum...

Three sample information retrieval systems, archie, autoLib, and WAIS, are compared as to their expressiveness and usefulness — first, in the general context of information retrieval, and then as prospective software reuse repositories. While the representational capabilities of these systems are limited, they provide a useful foundation for future repository efforts, particularly from the pers...

The objective of this effort is: (1) understand the physical processes acting above and below the airwater interface in rivers that drive the coherent structures in the thermal skin observed in the infrared imagery; (2) develop the capability to use airborne time-series infrared imagery to derive surface currents in rivers and estuaries; and (3) use this emerging capability to explore river hyd...

Recent network information retrieval systems are compared for their expressiveness and usefulness — first, in the general context of information retrieval, and then as prospective software reuse repositories. While the representational capabilities of these some of these systems are limited, they provide a useful foundation for future repository efforts, particularly from the perspective of rep...

In this paper, we evaluate Scalable Coherent Interface (SCI) as avionics real-time network. An OPNET based SCI node model is established. The results of our preliminary experiments show that a certain utilization of network load should be maintained in order to guarantee the timely delivery of real-time messages in avionics system where basic SCI ring is adopted.

A diagrammatic method is presented for averaging over the circular ensemble of random-matrix theory. The method is applied to phase-coherent conduction through a chaotic cavity (a “quantum dot”) and through the interface between a normal metal and a superconductor.

The paper contrasts a list-based approach to interface design with a structured, analytical, taxonomic approach. The taxonomy employed categorizes behaviour in ‘orthogonal’ terms: manipulation, selection, symbol mediation. It is argued that the taxonomical approach permits more coherent design responses to the needs of special users.
