We consider entanglement witnesses arising from positive linear maps which generate exposed extremal rays. We show that every entanglement can be detected by one of these witnesses, and this witness detects a unique set of entanglement among those. Therefore, they provide a minimal set of witnesses to detect all entanglement in a sense. Furthermore, if those maps are indecomposable then they de...

An observable W that distinguishes all the unentangled states from some entangled states is called a witness. We consider witnesses on n qbits, and use the following normalization: A witness W satisfies |tr(W ρ)| ≤ 1 for all separable states ρ, while W > 1, with the norm being the maximum among the absolute values of the eigenvalues of W. Although there are n-qbit witnesses whose norm is expone...

This research examined the impact of eyewitness identification decisions on student-investigators. Undergraduates played the role of police investigators and interviewed student-witnesses who had been shown either a good or poor view of the perpetrator in a videotaped crime. Based on information obtained from the witness, student-investigators then chose a suspect from a database containing inf...

Information systems with witnesses have been introduced in [13] as a logic-style representation of L-domains: The category of such information systems with approximable mappings as morphisms is equivalent to the category of L-domains with Scott continuous functions, which is known to be Cartesian closed. In the present paper a direct proof of the Cartesian closure of the category of information...

OBJECTIVES To identify key themes related to tobacco advertising and promotion in testimony provided by tobacco industry-affiliated witnesses in tobacco litigation, and to present countervailing evidence and arguments. METHODS Themes in industry testimony were identified by review of transcripts of testimony in the Tobacco Deposition and Trial Testimony Archive (http://tobaccodocuments.org/da...
