We present results from an experiment similar to one performed by Packard [24], in which a genetic algorithm is used to evolve cellular automata (CAs) to perform a particular computat iona l t ask . Packard examined the frequency of evolved CA rules as a function of Langton's A par amet er [17]; he interpret ed t he results of his experiment as giving evidence for two hypotheses: (1) CA rules t...

Bisantrene pharmacokinet ics was studied in five patients. Plasma elimination was biphasic with t~/2 o~ of 65 min ...

Ce travail aborde le potentiel des travaux concernant l’antifragilité (Taleb, 2012 ; 2013) pour notamment compléter concept de résilience à l’échelle individuelle et organisationnelle. Nous proposons une distinction entre fragile, résilient l’antifragile. Ces capacités se distinguent par la nature décisions prise en contexte crise, ...

In this paper, we prove the co-NP-completeness of the following decision problem: \given a 2-dimensional cellular automaton A, is A injective when restricted to nite conngurations not greater than its length?" In order to prove this result, we introduce two decision problems concerning respectively Turing Machines and tilings that we prove NP-complete. We then present a transformation of proble...

A new linear sweep vo ltammetric (LSV) assay of fsDNA based on its interaction with neutra l red (N R) is presented. At pH 8.0 Britton-Robinson (8-R) buffe r solutio n, the dye can bind with DNA to form a supramolec ular complex , wh ich results in the decrease of the linear sweep voltammetric reductive peak current at -0.60 V (vs. SCE) on the mercury e lec trode. The binding reaction is comple...

This theory defines a type constructor representing the free Boolean algebra over a set of generators. Values of type (α)formula represent propositional formulas with uninterpreted variables from type α, ordered by implication. In addition to all the standard Boolean algebra operations, the library also provides a function for building homomorphisms to any other Boolean algebra type. 1 Free Boo...
