Do Motifs Reflect Evolved Function? – No Convergent Evolution of Genetic Regulatory Network Subgraph Topologies
(2008-10)
Methods that analyse the topological structure of networks have recently become quite popular. Whether motifs (subgraph patterns that occur more often than in randomized networks) have specific functions as elementary ...
Evolution and morphogenesis of differentiated multicellular organisms: autonomously generated diffusion gradients for positional information
(MIT Press, 2008)
Development is the powerful process involving a genome in the transformation from one egg cell to a multicellular organism with many cell types. The dividing cells manage to organize and assign themselves special, ...
Algebraic properties of automata associated to Petri nets and applications to computation in biological systems
(2008)
Biochemical and genetic regulatory networks are often modeled by Petri nets. We study the algebraic structure of the computations carried out by Petri nets from the viewpoint of algebraic automata theory. Petri nets comprise ...
Drumming with a humanoid robot : results from human-robot interaction studies
(Institute of Electrical and Electronics Engineers (IEEE), 2008)
Emergent dynamics of turn-taking interaction in drumming games with a humanoid robot
(Institute of Electrical and Electronics Engineers (IEEE), 2008)
Regulation of gene regulation - smooth binding with dynamic affinity affects evolvability
(Institute of Electrical and Electronics Engineers (IEEE), 2008)
Anticipating future experience using grounded sensorimotor informational relationships
(MIT Press, 2008)
Operational definitions and applications of the sensorimotor experience of an artificial embodied organism are presented along with a mathematical metric for distance between experiences based on Shannon information. We ...
Bio-logic: gene expression and the laws of combinatorial logic
(2008)
At the heart of the development of fertilized eggs into fully formed organisms and the adaptation of cells to changed conditions are genetic regulatory networks (GRNs). In higher multi-cellular organisms, signal selection ...
On preferred states of agents: how global structure is reflected in local structure
(MIT Press, 2008)
We investigate the correlation between the information theoretic measure of empowerment and the graph theoretic measure of closeness centrality, to better understand the structural conditions that must exist in a world for ...
