The self‐organization of genomes [PDF]
Complexity, 2009 AbstractMenzerath‐Altmann law is a general law of human language stating, for instance, that the longer a word, the shorter its syllables. With the metaphor that genomes are words and chromosomes are syllables, we examine if genomes also obey the law. We find that longer genomes tend to be made of smaller chromosomes in organisms from three different ...

Motivated self-organization [PDF]
2017 12th International Workshop on Self-Organizing Maps and Learning Vector Quantization, Clustering and Data Visualization (WSOM), 2017 We present in this paper a variation of the self-organizing map algorithm where the original time-dependent (learning rate and neighborhood) learning function is replaced by a time-invariant one. The resulting self-organization does not fit the magnification law and the final vector density is not directly proportional to the density of the ...

Information and Self-Organization [PDF]
Entropy, 2016 The process of “self-organization” takes place in open and complex systems that acquire spatio-temporal or functional structures without specific ordering instructions from the outside. [...]

Science, 2005 In origami, form follows the sequential spatial organization of folds. This requires continuous intervention and raises a natural question: Can origami arise through self-organization? We answer this affirmatively by examining the possible physical origin for the Miura-ori leaf-folding patterns that arise naturally in insect wings, leaves, and other ...

Oscillatory rheotaxis of artificial swimmers in microchannels
Nature Communications, 2022 Biological and artificial microswimmers often navigate channels under external flow, where in many biomicroswimmers the active upstream motion is oscillatory. Here the authors demonstrate that regular, controllable, and reproducible oscillatory rheotaxis

The statistical geometry of material loops in turbulence
Nature Communications, 2022 Turbulent flows are observed in atmosphere, ocean, and technology, with turbulent mixing due to stretching and folding of material elements. The authors analyze a geometric perspective of this process and uncover statistical properties of an ensemble of ...

Randomized Self-Organizing Map [PDF]
Neural Computation, 2021 We propose a variation of the self-organizing map algorithm by considering the random placement of neurons on a two-dimensional manifold, following a blue noise distribution from which various topologies can be derived. These topologies possess random (but controllable) discontinuities that allow for a more flexible self-organization, especially with ...

Minimum entropy production by microswimmers with internal dissipation
Nature Communications, 2023 The energy dissipation and entropy production by self-propelled microswimmers differ profoundly from passive particles pulled by external forces.
