Digital networks and the capability of addressable sensing devices ooer new challenges for system theory. Rather than reading sensors continuously or periodically , as has traditionally been done, addressable sensing devices allow readings to be taken aperiodically and only as needed. In this paper, we introduce the notion of a sensing policy to determine which sensors should be read and when. ...

We introduce a set of iterative equations that exactly solves the size distribution of components on small arbitrary graphs after the random removal of edges. We also demonstrate how these equations can be used to predict the distribution of the node partitions (i.e., the constrained distribution of the size of each component) in undirected graphs. Besides opening the way to the theoretical pre...

The fragmentation of knowledge management as a field and as an area of research poses serious theoretical challenges for researchers. The viability of KM rests on how the community responds to these challenges, but it also depends on how they garner empirical support for their purported theories. One aspect of this would involve the evaluation of the evidence provided in KM research. This paper...

We study the process ¯ pp → J/ψ + γ + X at the Tevatron energy (√ s = 1.8 TeV). The perturbative QCD contributions to this process from the gluon-fusion and the fragmentation mechanisms are computed. For the entire range of p T that can be probed at the Tevatron, the fusion contribution is found to be dominant. Consequently the QCD prediction for this process has better precision than the purel...

Academics, politicians, and journalists are often highly critical of U.S. firms for holding too much cash. Cash holdings are stockpiled free-cash flow and incur substantial opportunity costs from the perspectives of economics. However, behavioral theory highlights the benefits of cash holdings as fungible slack resources facilitating adaptive advantages. We use the countervailing forces embodie...

The state of the art of the theoretical calculations for heavy quarks photoproduc-tion is reviewed. The full fixed order next-to-leading order massive calculation and the resummation of large log(p T /m) terms for differential cross sections are described. The implementation of a non-perturbative fragmentation function describing the c → D * meson transition is also discussed.

We discuss a number of ways in which single arm and coincident measurements of electroproduction on proton and nuclear targets can test fundamental QCD phenomena and provide constraints on hadronic wavefunctions. The topics include tests of color transparency, predictions for charm production at threshold, formation zone phenomena, and non-additive nuclear effects. We particularly emphasize the...

We review the state-of-the-art of our understanding of heavy quark fragmentation. Recent e + e − data for B mesons are compared to the most up-to-date theoretical predictions, and the need for inclusion of a non-perturbative component is discussed. Experimental analyses in moments space are suggested, and it is pointed out how perturbative and non-perturbative contributions are to be properly m...

This paper explores a new mechanism for B production in which a b quark combines with a light parton from the hard-scattering process before hadronizing into the B hadron. This recombination mechanism can be calculated within perturbative QCD up to a few nonperturbative constants. Though suppressed at large transverse momentum by a factor mb/p 2 ⊥ relative to b fragmentation production, it can ...

We show that experimental data are in very good agreement with predictions from the string fragmentation model by Bowler and Morris. We present a physical interpretation and discuss the relation to results obtained from Perturbative QCD and Local Hadron Parton Duality (LPHD). We also present implications for Bπ correlations and the possibility to use these as a tag to study CP violation in B de...
