Eight genera and 21 species of the tribe Anisoscelini (Coreidae, Coreinae) are recorded in Argentina: Anisoscelis foliaceus (Fabricius); Coribergia declivicollis (Berg); Dalmatomammurius vandoesburgi (Brailovsky); Holymenia hystrio (Fabricius); Leptoglossus chilensis (Spinola); L. cinctus (Herrich-Schaeffer); L. concolor Walker; L. crassicornis (Dallas); L. dentatus Berg; L. fasciatus (Westwood...

Let Ln denote the lowest crossing of the 2n × 2n square box B(n) centered at the origin for critical site percolation on Z 2 or critical site percolation on the triangular lattice imbedded in Z 2 , and denote by Qn the set of pivotal sites along this crossing. On the event that a pivotal site exists, denote the minimum height that a pivotal site attains above the bottom of B(n) by Mn := min{m ≥...

The starting points for this paper are simple descriptions of the norm and strong* closures of the unitary orbit of a normal operator in a von Neumann algebra. The statements are in terms of spectral data and do not depend on the type or cardinality of the algebra. We relate this to several known results and derive some consequences, of which we list a few here. Exactly when the ambient von Neu...

accuracy Nathan Berg*, Chunyu Chen** and Murat Kantarcioglu*** Introduction Those who study organizational failure commonly diagnose the root cause as breakdowns in information sharing. A vivid example is the failure of US intelligence agencies to share information that, in retrospect, might have prevented 9/11. This interpretation holds that the FBI and CIA could have shared important leads to...
