A succinct SAT solver is presented that exploits the control provided by delay declarations to implement watched literals and unit propagation. Despite its brevity the solver is surprisingly powerful and its elegant use of Prolog constructs is presented as a programming pearl.

The concept of an Intuitionistic Fuzzy Modal Topological Structure (IFMTS) or for brevity, Topology (IFMT), is introduced. It proved that the two standard intuitionistic fuzzy topological operators C and I, modal ? ? generate different IFMTs. Some basic properties both IFMTs are discussed. important These will be a basis next research on IFMTSs. Ideas future development IFMT theory formulated.

We answer some questions about the existence of graphs with a given endotype posed in B* ottcher and Knauer (Discrete Math. 109 (1992) 45–57). All de8nitions and needed terminology can be found there and for brevity they will not be repeated here. All results have been obtained by computer calculations. c © 2003 Elsevier B.V.

Developments in computer and communication technologies over the past ten years aptly support the use of the term global village to describe the present worldwide provision and distribution of information. These technologies are increasingly being employed in Africa, but their presence is not widespread and evenly distributed. Librarians in Africa are establishing the basic tools and organizati...

T h e d a t a f r o m t w o c l i n i c a l trials(Symplicity HTN-1 and Symplicity HTN-2) has proven the safety and efficacy of RD for treating the patients with resistant hypertension.1,2 Symplicity HTN-1 was a non-rand...

Motivated by the need to cope with floods of data, algorithm design is undergoing profound changes. Self-improvement, online property-preserving filtering, uncertainty, sublinearity and property testing are all parts of the story. I will discuss some of these exciting developments with an emphasis on its geometric aspects.

ion Level Incompatibility Generalization Conflicts Aggregation Conflicts (Semantic Relationship) (Semantic Relationship) Figure 8: Abstraction level incompatibilities and the likely types of semantic proximities In this case there is an inclusion relationship between two con icting objects and hence, they may be considered to have a semantic relationship. semPro(O1, O2) = <ALL, Generalization, ...

Metastases are tumors that develop at a distance from their primary origin and are responsible for the death of 90% of cancer patients. For over a century the notion of seed (migrating cells) and soil (the locus where those cells anchor) provided an accurate account of which were the protagonists in their genesis. Despite aggressive efforts to unravel the dynamics involving migrating cells and ...
