In the virtual manufacturing process based on grid technology, user and resource provider share resource and service connected through different virtual enterprises. In order to realize the target, virtual enterprise will manage the enterprises in its lower level, and then the hierarchically distributed environment will be formed.

In an editorial not long ago in the Proceedings of the National Academy of Sciences, Richard J. Roberts, who won the 1993 Nobel Prize in medicine, issued a call to journals in the life sciences to make their contents available for posting online at no charge after a suitable delay--one month, or perhaps six months, after publication. Specifically, he urged them to deposit the articles they publ...

The control-word negotiation mechanism specified in RFC 4447 has a problem when a PE (Provider Edge) changes the preference for the use of the control word from NOT PREFERRED to PREFERRED. This document updates RFC 4447 and RFC 6073 by adding the Label Request message to resolve this control-word negotiation issue for single-segment and multi-segment pseudowires. Information about the current s...

Furthermore, some applications, or better application...

We present an improved search for single top quarks in two production modes, s-channel (tb) and t-channel (tqb). The search is performed in the electron+jets and muon+jets decay channels, with one or more b-tagged jets, on nearly 370 pb−1 of DØ Run II data collected between August 2002 and October 2004. Impact-parameter based b-quark tagging is used to select signal-like events. We use a likeli...

This paper extends the political agency approach to an environment in which voting may be divided between informed and instrumental, informed and ‘expressive’ and uninformed due to ‘rational irrationality’. It constructs a model where politicians may be good, bad or populist. Initially the existence of only good and populist politicians is assumed and the incentives for good politicians to pool...

Focusing on a femtocell communications market, we study the entrant network service provider’s (NSP’s) longterm decision: whether to enter the market and which spectrum sharing technology to select to maximize its profit. This long-term decision is closely related to the entrant’s pricing strategy and the users’ aggregate demand, which we model as medium-term and short-term decisions, respectiv...

The literature on integrated care is limited with respect to practical learning and experience. Although some attention has been paid to organizational processes and structures, not enough is paid to people, relationships, and the importance of these in bringing about integration. Little is known, for example, about provider engagement in the organizational change process, how to obtain and mai...
