Inactivation of plf>'"l"IAand other tumor suppressor genes has been associated with promoter region hypermethylation in neoplasia. However, direct proof for aberrant DNA methylation as an independent event for loss of gene function has been difficult to obtain. We addressed this question in the colon carcinoma cell line HCT116, which contains one alÃ-eleof plSnk4A with a coding region fra mes h...

Resequencing problem is a crucial issue in communication systems, databases, production and information networks because correct processing of information by them may often be performed only if original order of packets, queries, jobs is preserved. In this paper consideration is given to one of the queueing systems that may model processes of discrete nature where resequencing phenomenon may ar...

Examines the individual buyer-supplier relationships of the four major Japanese automobile manufacturers. Building on the relationship marketing and the interorganizational trust literature, relates their supplier management practices to the type of supplier organizations they use, the relative sales revenues, number of employees, and profitability of both buyers and suppliers, and the level of...

A set A is m-reducible (or Karp-reducible) to B i there is a polynomial-time computable function f such that, for all x, x 2 A () f(x) 2 B. Two sets are: 1-equivalent i each is m-reducible to the other by one-one reductions; p-invertible equivalent i each is m-reducible to the other by one-one, polynomial-time invertible reductions; and p-isomorphic i there is an m-reduction from one set to the...

Diversity in teams, while potentially beneficial, increases the likelihood that individual team members will define the team’s task differently, leading to gaps in their perceptions of what is important for team task execution. These representational gaps are likely to create conflict as teammates try to solve what are essentially incompatible problems. We articulate how these representational ...
