Reversible, Irreversible and Optimal -machines
There are two quite diierent possibilities for implementing linear head reduction in-calculus. Two ways which we are going to explain brieey here in the introduction and in details in the body of the paper. The paper itself is concerned with showing an unexpectedly simple relation between these two ways, which we term reversible and irreversible, namely that the latter may be obtained as a natu...

متن کاملFrom Reversible to Irreversible Computations
In this paper we study the relation between reversible and irreversible computation applicable to different models of computation — here we are considering classical and quantum computation. We develop an equational theory of reversible computations and an associated theory of irreversible computations which is obtained by marking some inputs as preinitialised heap and some outputs as garbage t...
متن کاملReversible Simulation of Irreversible Computation
Computer computations are generally irreversible while the laws of physics are reversible. This mismatch is penalized by among other things generating excess thermic entropy in the computation. Computing performance has improved to the extent that eeciency degrades unless all algorithms are executed reversibly, for example by a universal reversible simulation of irreversible computations. All k...
متن کاملReversible and irreversible differentiation of cardiac fibroblasts
AIMS Differentiation of cardiac fibroblasts (Fbs) into myofibroblasts (MyoFbs) is responsible for connective tissue build-up in myocardial remodelling. We examined MyoFb differentiation and reversibility. METHODS AND RESULTS Adult rat cardiac Fbs were cultured on a plastic substratum providing mechanical stress, with conditions to obtain different levels of Fb differentiation. Fb spontaneousl...
