The transient behavior of the I-dimensional 2-state 3-input cellular automaton rule 110, one of the simplest "edge of chaos" cellular automata, is investigated numerically. The simulations show that the average transient time Tave increases algebraically with system size N, Tave ~ N"', with a "" 1.08, and that the density of propagating objects (gliders) decays with time as ngl ~ r'Y with I "" ...

In this paper, a single-soliton two-component cellular automaton (CA) model of waves is presented as mobile self-localizations, also known as particles, waves, or gliders, in addition to its version with memory. The model is based on coding sets of strings where each chain represents a unique mobile self-localization. The original soliton models in CAs proposed with filter automata are briefly ...

A derivative of rhodamine 110 has been designed and assessed as a probe for cytochrome P450 activity. This probe is the first to utilize a 'trimethyl lock' that is triggered by cleavage of an ether bond. In vitro, fluorescence was manifested by the CYP1A1 isozyme with k(cat)/K(M)=8.8x10(3)M(-1)s(-1) and K(M)=0.09microM. In cellulo, the probe revealed the induction of cytochrome P450 activity by...
