We define five properties of symbol representations (called the Five M's) that together provide a powerful and flexible symbol processing facility. Our ideal symbol structures arc Mobile, Memorable, Meaningful, Malleable, and Modifiable. Conventional symbol processing architectures, such as Lisp on von Neumann machines, support some of these properties, but others seem to require flexibility an...

A very general commentary on the program camex, accompanied by an assortment of experiments which can be performed using the cam/pc board. These include the use of one, two, and three dimensional automata, although the primary utility of the board lies with two dimensional automata evolving on a 256x256 screen. Binary Moore and von Neumann neighborhoods are possible in each of the two half-cam'...

The Birkhoff-von Neumann Theorem has been proved many times in the literature with a number of different methods, some inductive, some constructive, some existential. We offer a new proof that is a little more direct than most, though nonconstructive.

Die präklinische Versorgung von Patienten im Rahmen eines Massenanfalls von Verletzten (MANV) ist mit der Priorisierung von Aufgaben und dem effizienten Einsatz verfügbarer Ressourcen verbunden. Die hierfür benötigte Information wird gegenwärtig auf Papierformularen und Kunststofftaschen dokumentiert und im persönlichen Gespräch, durch Melder sowie fernmündlich kommuniziert. Computerbasierte We...

Kurzfassung. Die endoskopische Untersuchung des Darms (Koloskopie) ist ein wichtiges Verfahren zur Diagnose und Therapie vieler Erkrankungen. Während der Koloskopie werden u. a. zu dokumentarischen Zwecken oder als Grundlage für die computergestützte Diagnose und Therapie Standaufnahmen erzeugt. Aufgrund der Peristaltik des Darms und der eingeschränkten Kontrolle über das Koloskop ist es schwie...

We study a simple variant of the von Neumann model of an expanding economy, in which multiple producers produce goods according to their production function. The players trade their goods at the market and then use the bundles acquired as inputs for the production in the next round. We show that a simple decentralized dynamic, where players update their bids proportionally to how useful the inv...

We use the concept of a regular object with respect to another object in an arbitrary category, defined in [3], in order to obtain the transfer of regularity in the sense of Zelmanowitz between the categories R−mod and S−mod, when S is an excellent extension of the ring R. Consequently, we obtain a result of [5]: if S is an excellent extension of the ring R, then S is von Neumann regular ring i...

We prove that for all 1 ≤ p ≤ ∞, p 6= 2, the L spaces associated to two von Neumann algebras M, N are isometrically isomorphic if and only if M and N are Jordan *-isomorphic. This follows from a noncommutative L Banach-Stone theorem: a specific decomposition for surjective isometries of noncommutative L spaces.

We prove a weak-type (1,1) inequality for square functions of noncommutative martingales that are simultaneously bounded in L and L. More precisely, the following non-commutative analogue of a classical result of Burkholder holds: ...

A general procedure for extending finite-dimensional "additive-like" representations for binary relations to infinite-dimensional "integral-like" representations is developed by means of a condition called truncation-continuity. The restriction of boundedness of utility, met throughout the literature, can now be dispensed with, and for instance normal distributions, or any other distribution wi...
