Matrix genetics, part 2: the degeneracy of the genetic code and the octave algebra with two quasi-real units (the genetic octave Yin-Yang-algebra) [PDF]
arXiv, 2008 Algebraic properties of the genetic code are analyzed. The investigations of the genetic code on the basis of matrix approaches ("matrix genetics") are described. The degeneracy of the vertebrate mitochondria genetic code is reflected in the black-and-white mosaic of the (8*8)-matrix of 64 triplets, 20 amino acids and stop-signals.

A GENDER EFFECT RELATED TO TEACHERS' CONCEPTIONS ON BIOLOGICAL GENDER DIFFERENCES. A SURVEY IN 14 COUNTRIES [PDF]
, 2009 In the context of the European research project Biohead-Citizen, 5,706 in-service and pre-service teachers from 14 countries (most in Europe, but also in Africa and Middle East) filled in a questionnaire containing 16 questions mainly related to the ...

A Monte Carlo Approach to Measure the Robustness of Boolean Networks
, 2012 Emergence of robustness in biological networks is a paramount feature of evolving organisms, but a study of this property in vivo, for any level of representation such as Genetic, Metabolic, or Neuronal Networks, is a very hard challenge.

Epigenetic therapy in allogeneic hematopoietic stem cell transplantation
Revista Brasileira de Hematologia e Hemoterapia, 2013 DNA methylation and other epigenetic phenomena appear to be relevant in the pathogenesis of several malignant disorders. DNA methyltransferases add methyl groups to cytosine-phosphate-guanine (CpG) islandsleading to gene promoter silencing.

A Novel Genetic Algorithm using Helper Objectives for the 0-1 Knapsack Problem [PDF]
arXiv, 2014 The 0-1 knapsack problem is a well-known combinatorial optimisation problem. Approximation algorithms have been designed for solving it and they return provably good solutions within polynomial time. On the other hand, genetic algorithms are well suited for solving the knapsack problem and they find reasonably good solutions quickly.

The genetic determinism of human performances. A comparison between teachers' conceptions in Finland and France [PDF]
, 2009 International audienceFinland has the best mean sciences scores among the OECD countries while France is in the OECD average (PISA 2006). Nevertheless, when measuring interactions between knowledge and values in teachers' conceptions, the comparison ...

Stability of Underdominant Genetic Polymorphisms in Population Networks [PDF]
arXiv, 2015 Heterozygote disadvantage is potentially a potent driver of population genetic divergence. Also referred to as underdominance, this phenomena describes a situation where a genetic heterozygote has a lower overall fitness than either homozygote. Attention so far has mostly been given to underdominance within a single population and the maintenance of ...

Positional Cartesian Genetic Programming [PDF]
arXiv, 2018 Cartesian Genetic Programming (CGP) has many modifications across a variety of implementations, such as recursive connections and node weights. Alternative genetic operators have also been proposed for CGP, but have not been fully studied. In this work, we present a new form of genetic programming based on a floating point representation.

Epigenetics and Language: The Minimalist Program, Connectionism and Biology [PDF]
, 2004 Chomsky claims that linguistics should be thought of as a branch of biology. Lorenzo and Longa claim that the Minimalist Program is better than previous approaches at connecting language to biology because it relies on epigenetic processes in ...

Within selection Dentro de la selección
Revista Chilena de Historia Natural, 2007 The synthetic theory of evolution proposes that biotic variations generated by mutation are mostly fixed, lost or maintained polymorphic by natural selection, with a marginal effect due to genetic drift.
