Estudio del comportamiento fractal espacial de la superficie del terreno, considerando factores del relieve climáticos, estructurales y litológicos

El presente estudio parte de la hipótesis de que hay una relación numérica entre la forma de la superficie geomórfica y los factores de modelado del relieve. La metodología utilizada es el análisis multifractal de las curvas de nivel de Modelos Digitales del Terreno de toda España. Para ello hemos utilizado software libre en todos los pasos. Los resultados obtenidos hacen pensar que esta correlación existe, en el factor climático (gradiente de precipitación máxima anual) y estructural (peligrosidad sísmica). El factor litológico no ha dado ajuste algo, probablemente debido a la falta de datos precisos.

Confidentiala "Mode 3" Systems Approach for Knowledge Creation, Diffusion and Use: Towards a 21st Century Fractal Innovation Ecosystem. ACES Working Paper (Report) No. 4, 2007

"Mode 3" allows and emphasizes the co-existence and co-evolution of different knowledge and innovation paradigms: the competitiveness and superiority of a knowledge system is highly determined by its adaptive capacity to combine and integrate different knowledge and innovation modes via co-evolution, co-specialization and coopetition [sic] of knowledge stock and flow dynamics. What results is an emerging fractal knowledge and innovation ecosystem, well-configured for the knowledge economy and society. The intrinsic litmus test of the capacity of such an ecosystem to survive and prosper in the context of continually glocalizing [sic] and intensifying competition represents the ultimate competitiveness benchmark with regards to the robustness and quality of the ecosystem's knowledge and innovation architecture and topology.

Genetic Codes with No Dedicated Stop Codon: Context-Dependent Translation Termination

The prevailing view of the nuclear genetic code is that it is largely frozen and unambiguous. Flexibility in the nuclear genetic code has been demonstrated in ciliates that reassign standard stop codons to amino acids, resulting in seven variant genetic codes, including three previously undescribed ones reported here. Surprisingly, in two of these species, we find efficient translation of all 64 codons as standard amino acids and recognition of either one or all three stop codons. How, therefore, does the translation machinery interpret a “stop” codon? We provide evidence, based on ribosomal profiling and “stop” codon depletion shortly before coding sequence ends, that mRNA 3′ ends may contribute to distinguishing stop from sense in a context-dependent manner. We further propose that such context-dependent termination/readthrough suppression near transcript ends enables genetic code evolution.
