On the notion of "von Neumann vicious circle" coined by John Backus

Long Waiting Times for Elective Hospital Care – Breaking the Vicious Circle by Abandoning Prioritisation

Background Policies assigning low-priority patients treatment delays for care, in order to make room for patients of higher priority arriving later, are common in secondary healthcare services today. Alternatively, each new patient could be granted the first available appointment. We aimed to investigate whether prioritisation can be part of the reason why waiting times for care are often...

Calculating Different Topological Indices of Von Neumann Regular Graph of Z_(p^α )

By the Von Neumann regular graph of R, we mean the graph that its vertices are all elements of R such that there is an edge between vertices x,y if and only if x+y is a von Neumann regular element of R, denoted by G_Vnr (R). For a commutative ring R with unity, x in R is called Von Neumann regular if there exists x in R such that a=a2 x. We denote the set of Von Neumann regular elements by V nr...

Can Programming Be Liberated from von Neumann Style? A Functional Style and Its Algebra of Programs, 1977

The 1977 A C M Taring Award was presented to John Backus at the A C M Annual Conference in Seattle, October 17. In introducing the recipient, Jean E. Sammet, Chairman of the Awards Committee, made the following comments and read a portion of the final citation. The full announcement is in the September 1977 issue of C o m m u n i c a t i o n s , page 681. "Probably there is nobody in the room w...

Reiter’s Properties for the Actions of Locally Compact Quantum Goups on von Neumann Algebras

Quantum State Reduction: An Operational Approach

A rigorous theory of quantum state reduction, the state change of the measured system caused by a measurement conditional upon the outcome of measurement, is developed fully within quantum mechanics without leading to the vicious circle relative to the von Neumann chain. For the basis of the theory, the local measurement theorem provides the joint probability distribution for the outcomes of lo...
