Inclusion dependencies and their interaction with functional dependencies

Marco A. Casanova, Ronald Fagin, Christos H. Papadimitriou
1984 Journal of computer and system sciences (Print)  
Inclusion dependencies, or INDs (which can say, for example, that every manager is an employee) are studied, including their interaction with functional dependencies, or FDs.  ...  INCLUSION DEPENDENCIES 31 Although INDs, like FDs, have a simple complete axiomatization, we show that the interaction of FDs and INDs is complex.  ...  ACKNOWLEDGMENTS The authors are grateful to David Johnson and Moshe Vardi, each of whom carefully read the paper and made helpful comments, and to Nick Pippenger for bringing Landau's result (mentioned  ...

Inclusion dependencies and their interaction with functional dependencies

Marco A. Casanova, Ronald Fagin, Christos H. Papadimitriou
1982 Proceedings of the 1st ACM SIGACT-SIGMOD symposium on Principles of database systems - PODS '82  
Inclusion dependencies, or INDs (which can say, for example, that every manager is an employee) are studied, including their interaction with functional dependencies, or FDs.  ...  It is shown that finite implication (implication over databases with a finite number of tuples) is the same as unrestricted implications for INDs, although finite implication and unrestricted implication  ...  Although the decision problem for FDs is decidable and the decision problem for INDs is decidable, we do not know whether the decision problem for FDs and INDs together is decidable.  ...

Mutual Diffusion of Inclusions in Freely Suspended Smectic Liquid Crystal Films

Zhiyuan Qi, Zoom Hoang Nguyen, Cheol Soo Park, Matthew A. Glaser, Joseph E. Maclennan, Noel A. Clark, Tatiana Kuriabova, Thomas R. Powers
2014 Physical Review Letters  
We study experimentally and theoretically the hydrodynamic interaction of pairs of circular inclusions in two-dimensional, fluid smectic membranes suspended in air.  ...  By analyzing their Brownian motion, we find that the radial mutual mobilities of identical inclusions are independent of their size but that the angular coupling becomes strongly size-dependent when their  ...  When the membrane has multiple inclusions, the mobilities of the inclusions depend not only on their size and the drag from the surrounding fluid(s) but also on the hydrodynamic interactions between them  ...
