Dr. Alfred Hoppe of Forschuugsgruppe LIMAS has developed a pro / cedure for a reversible data flow (Figure I). 'In the matrix/%hree ~ different quantities are connected together. For analysis~he grammatical description of an inflected form is determined by combining the inflection class with the ending. For example the German verb ~ehen is composed of the stem ~eh and the ending e_~u. The lexic...

Labile metal complexes have a useful coordination bond; which is weaker than a covalent C–C bond and is reversibly and dynamically formed and dissociated. Such labile metal complexes also can be used to construct chiral shapes and offer dynamic conversion of chiral molecular shapes in response to external stimuli. This review provides recent examples of chirality induction and describes the dyn...

Hardware Description Languages (HDLs) allow for the efficient synthesis of large and complex circuits. Consequently, researchers also investigated their potential in the domain of reversible logic. Here, existing HDL-based synthesis approaches suffer from the significant drawback of employing additional circuit lines in order to buffer intermediate results. In this work, we investigate the poss...

The fact that macroscopic systems approach thermal equilibrium may seem puzzling, for example, because it may seem to conflict with the time-reversibility of the microscopic dynamics. We here prove that in a macroscopic quantum system for a typical choice of “nonequilibrium subspace”, any initial state indeed thermalizes, and in fact does so very quickly, on the order of the Boltzmann time τB :...

In his 2003 paper"Towards an algebraic theory of Boolean circuits", Lafont notes that the class of reversible circuits over a set of k truth values is finitely generated when k is odd. He cites a private communication for the proof. The purpose of this short note is to make the content of that communication available.

Patent retrieval is generally considered to be a recall-oriented information retrieval task that is growing in importance. Despite this fact, precision based scores such as mean average precision (MAP) remain the primary evaluation measures for patent retrieval. Our study examines different evaluation measures for the recall-oriented patent retrieval task and shows the limitations of the curren...

in this note we introduce the notion of weak mccoy rings as a generalization of mccoy rings, and investigate their properties. also we show that, if is a semi-commutative ring, then is weak mccoy if and only if is weak mccoy.
