Updating almost complete trees or one level makes all the difference,ry search trees have an amortized update cost of Θ(.), we demonstrate that almost complete binary search trees have an amortized update cost of .(log..). Thus, they are an attractive alternative for those situations that require fast retrieval, that is, log .+.(1) comparisons, and have few updates.

Efficient checking of computations,an also be restricted to be logspace with essentially no loss in performance. We also use this result to show that every set in . is equal to .(.) where . is a homomorphism and . is accepted by a one-way probabilistic logspace machine.

Hard promise problems and nonuniform complexity,ion of PP-., then .∈P./.. From this result, it follows that if . is ≤.-hard for NP, then all solutions of PP-. are hard for NP under a reduction that generalizes both ≤. and ≤.. Specifically, if . is NP-hard, then all solutions of PP-. are ... . The main theorem that leads to this result sta

Towards a process semantics in the logic programming style,on..Actually, the semantic definitions are given at the very basic level of transition systems, and it is shown how to represent a logic program with such a system. Therefore, the same constructions can be applied to every formalism representable as a transition system.

Relation-sorted algebraic specifications with built-in coercers: Basic notions and results,al than order-sorted specification, we et similar results, e.g. concerning the construction of initial algebras and a complete deduction system. Our approach may serve as a general framework for investigating subtypes as injective as well as non-injective conversion.

Klaus Ambos-Spies,Steven Homer,Robert I. Soareifferent epithelial–mesenchymal states may affect metastatic organotropism. In this review, we summarize the current understanding of pancreatic cancer cell plasticity and metastasis, and highlight current model systems that can be used to study these phenomena.
