We introduce the NP-hard graph-based data clustering problem s-Plex Cluster Vertex Deletion, where the task is to delete at most k vertices from a graph so that the connected components of the resulting graph are s-plexes. In an s-plex, every vertex has an edge to all but at most s − 1 other vertices; cliques are 1-plexes. We propose a new method for kernelizing a large class of vertex deletion...

Enterprise Information Systems (EIS) have become the core information processing architecture of large businesses. This study examines the role of Knowledge Social Networks (KSN) in facilitating EIS-related knowledge acquisition accounting for the domain expertise of knowledge sources, its interplay with user task complexity, and their impact on EIS implementation. While research on KSNs has co...

The title compound, KSn(2)(PO(4))(3), belongs to the NASICON-type family of phosphates with the space group R[Formula: see text]. Its structure is constructed by very regular [with P-O distances ranging from 1.513 (6) to 1.522 (6) Å] PO(4) tetra-hedra and SnO(6) octa-hedra on the 3. axis, which are linked by O atoms, forming an [Sn(2)(PO(4))(3)] framework. The K atoms occupy the [Formula: see t...

the aitamir formation (albian- cenomanian) in the kopet- dagh basin consists of fine to medium grained sandstone, siltstone, shale and limestone. its lower contact with the sanganeh formation is gradual and its upper contact with the abderaz formation is unconformable. field and petrographic studies of the aitamir formation in artenj and ghorghoreh sections, located in bazangan area- east of ko...

Let Sn be the symmetric group on n letters, k be a field of characteristic p and D be the irreducible kSn-module corresponding to a p-regular partition λ of n, as in [12]. By tensoring D with the 1-dimensional sign representation we obtain another irreducible kSn-module. If p = 0, D λ ⊗ sgn ∼= D ′ , where λ′ is the conjugate of the partition λ, and if p = 2, we obviously have that D ⊗ sgn ∼= D....

The associative operad is a certain algebraic structure on the sequence of group algebras of the symmetric groups. The weak order is a partial order on the symmetric group. There is a natural linear basis of each symmetric group algebra, related to the group basis by Möbius inversion for the weak order. We describe the operad structure on this second basis: the surprising result is that each op...
