Decoherence and multipartite entanglement.

Physical review letters

Carvalho AR, Mintert F, Buchleitner A.
PMID: 15601133
Phys Rev Lett. 2004 Dec 03;93(23):230501. doi: 10.1103/PhysRevLett.93.230501. Epub 2004 Dec 01.

We study the dynamics of multipartite entanglement under the influence of decoherence. A suitable generalization of concurrence reveals distinct scaling of the entanglement decay rate of Greenberger-Horne-Zeilinger and W states, for various environments.

Pattern matching through Chaos Game Representation: bridging numerical and discrete data structures for biological sequence analysis.

Algorithms for molecular biology : AMB

Vinga S, Carvalho AM, Francisco AP, Russo LM, Almeida JS.
PMID: 22551152
Algorithms Mol Biol. 2012 May 02;7(1):10. doi: 10.1186/1748-7188-7-10.

BACKGROUND: Chaos Game Representation (CGR) is an iterated function that bijectively maps discrete sequences into a continuous domain. As a result, discrete sequences can be object of statistical and topological analyses otherwise reserved to numerical systems. Characteristically, CGR coordinates...
