Intersemiotic translation (IT) was defined by Roman Jakobson (The Translation Studies Reader, Routledge, London, p. 114, 2000) as “transmutation of signs”—“an interpretation of verbal signs by means of signs of nonverbal sign systems.” Despite its theoretical relevance, and in spite of the frequency in which it is practiced, the phenomenon remains virtually unexplored in terms of conceptual modeling, especially from a semiotic perspective. Our approach is based on two premises: (i) IT is fundamentally a semiotic operation process (semiosis) and (ii) (...) IT is a deeply iconic-dependent process. We exemplify our approach by means of literature to dance IT and we explore some implications for the development of a general model of IT. (shrink)

The Aristotelian axiom that function follows form was beautifully instantiated in molecular biology by the discovery of DNA’s structure that immediately suggested how DNA might work as depository and vehicle for genetic information. However, later on molecular biology became infatuated with the gene that became the center of the universe. This gene-centered viewpoint is an obstacle for the emerging field of evo-devo aiming at finding the causal connections between evolution and biological development. Here it is argued that molecular biology must (...) reject the narrow-minded causality associated with the gene-centered view and so it must recover to the spirit of Aristotelian natural history and its four types of causation in order to foster the evo-devo field of research.

Two hundred years after Darwin’s birth, the evolution of living systems is an accepted fact but there is scope for controversy on the mechanisms involved in such a process. Mainstream neo-Darwinism champions the role of natural selection (NS) as the fundamental cause of the evolutionary process as well as of random, contingent events at the genetic level as the main source of variation upon which NS performs its causal role. Thus, according to neo-Darwinism the course of biological evolution is quite (...) unpredictable and the past can only be partially reconstructed by means of a historical narrative.This second-class status for biology within the natural sciences as a merely descriptive, historical science results from the chronic neglect of biological form in the neo-Darwinian discourse. Hereunder I discuss the need for reintroducing form as the central object of biology, aiming at the identification of the general and fundamental principles of biological form. Such a formal biology may go beyond simple historical description achieving a complete, rational explanation of how previous and current morphologies corresponding to identifiable species were established, and so providing a rational foundation for predicting the possible outcomes of future biological evolution on earth and perhaps elsewhere in the universe.

The paper introduces mathematical encoding for subjective experience and meaning in natural cognition. The code is based on a quantum-theoretic qubit structure supplementing classical bit with circular dimension, functioning as a process-causal template for representation of contexts relative to the basis decision. The qubit state space is demarcated in categories of emotional experience of animals and humans. Features of the resulting spherical map align with major theoreties in cognitive and emotion science, modeling of natural language, and semiotics, suggesting several generalizations (...) and improvements. The developed model bridges psychological, quantum-theoretic, and semiotic perspectives, allowing for an integrative account of subjectivity, agency, and meaning in living Nature.Graphical abstract.

The basic premise of biosemiotics as a discipline is that there are elementary processes linking signifying strategies in all forms of animate life. Correspondingly, the discoveries of biosemiotics should, in principle, be capable of revealing new insights about human signification. In the present article, I show that this is in fact the case by constructing a biosemiotic model that links advertising strategies with corresponding structures in animal predation. The methodological framework for this model is the catastrophe theory of René Thom. (...) The end result is a revised understanding of an ostensibly cultural phenomenon that demonstrates its continuity with signalling processes conventionally associated with the natural world. (shrink)

The aim of this communication is to consider morphological processes in sociology, mainly through the study of the stability of forms of sociality. At the same time, it aims to study the regulation of constraints, related to an increasingly conflictual environment, through political organization. We use a specific theoretical framework: the catastrophe theory developed by René Thom in topology, further developed by Claude Bruter from a physics point of view, and reworked by Jacques Viret in biology. The idea is to (...) show the existence of archetypal processes organizing social forms. (shrink)

We describe reversible adaptive trees, a class of stochastic algorithms modified from the formerly described adaptive trees. They evolve in time a finite subset of an ambient Euclidean space of any dimension, starting from a seed point and, accreting points to the evolving set, they grow branches towards a target set which can depend on time. In contrast with plain adaptive trees, which were formerly proven to have strong convergence properties to a static target, the points of reversible adaptive trees (...) are removed from the tree when they have not been used recently enough in a path from the root to an accreted point. This, together with a straightening process performed on the branches, permits the tree to follow some moving targets and still remain adapted to it. We then discuss in what way one can see such reversible trees as a model for a qualitative property of resilience, which leads us to discuss qualitative modeling. (shrink)

Category theory has been proposed as the ultimate algebraic model for biology. We review the Ehresmann–Vanbremeersch theory in the context of other mathematical approaches.
