Distance modulation competitive co-evolution method to find initial configuration independent cellular automata rules [PDF]

open access: yes, 1999
IEEE International Conference on Systems, Man, and Cybernetics. Tokyo, 12-15 October 1999.One of the main problems in machine learning methods based on examples is the over-adaptation.

Consideraciones en tomo a "La fatal arrogancia"

open access: yesTópicos, 2013
The author makes here an analysis of Friedrick A. Hayek's The Fatal Conceit. This thinker considers that the best political-economical system for human civilization is capitalism, which has arised in an spontaneous, evolutive and adaptative way without ...

Opportunities and Threats of Mediterranean Evergreen Sclerophyllous Woody Species Subjected to Extreme Drought Events

open access: yesApplied Sciences, 2020
Climate change and extreme drought and heat events impact the Mediterranean evergreen sclerophyllous vegetation in South Europe, especially in Iberian and Italian peninsula, where widespread crown defoliation and dieback have been observed since the 90s ...

Genome Evolution: Recombination Speeds Up Adaptive Evolution [PDF]

open access: yesCurrent Biology, 2003
Mutual interference among linked genetic sites subject to selection may reduce the level of adaptation. A recent study detected this effect using data on protein sequence evolution and codon usage in Drosophila.

Co-evolution of mitochondrial tRNA import and codon usage determines translational efficiency in the green alga Chlamydomonas.

open access: yesPLoS Genetics, 2012
Mitochondria from diverse phyla, including protozoa, fungi, higher plants, and humans, import tRNAs from the cytosol in order to ensure proper mitochondrial translation.

Evolution, Adaptation, and Supercoiling [PDF]

open access: yesJournal of Bacteriology, 2007
Geometrical and, to some extent, physical and informational properties of covalently closed DNA molecules (or molecules that can be ideally viewed as closed) are determined by their connectivity, i.e., the number of times one strand of DNA is topologically linked to another.

Evolution: Sex Limits Adaptation [PDF]

open access: yesCurrent Biology, 2015
Evolution is affected by survival of individuals and by mate choice, but how sexual selection affects adaptation remains unclear. A new study finds that sexual selection can limit adaptation by causing male-induced harm to females and thus opposing natural selection.

An evolutionary model with Turing machines [PDF]

open access: yes, 2007
The development of a large non-coding fraction in eukaryotic DNA and the phenomenon of the code-bloat in the field of evolutionary computations show a striking similarity.

Sequence variability of Rhizobiales orthologs and relationship with physico-chemical characteristics of proteins

open access: yesBiology Direct, 2011
Background Chromosomal orthologs can reveal the shared ancestral gene set and their evolutionary trends. Additionally, physico-chemical properties of encoded proteins could provide information about functional adaptation and ecological niche requirements.

On Resilient Behaviors in Computational Systems and Environments

open access: yes, 2015
The present article introduces a reference framework for discussing resilience of computational systems. Rather than a property that may or may not be exhibited by a system, resilience is interpreted here as the emerging result of a dynamic process. Said
