Biological systems are difficult to understand complex systems. Scientists continue to create models to simulate biological systems but these models are complex too; for this reason, new reduction methods to simplify complex biological models into simpler ones are increasingly needed. In this paper, we present a way of reducing complex quantitative...

Several biological systems such as the biomechanics of human heart, locomotion, and phyllotaxis of plants present a harmonic behavior because their fractal structure are associated to the golden ratio. The golden ratio (Φ = 1.618033988749…), also known as Phi, golden mean, golden section or divine proportion, is an irrational constant found in vari...

In this paper we show how Networks of Polarized Splicing Processors (NPSPs) can be used as problem solvers. We give a detailed uniform solution for the 3-coloring problem using O(m*n) time and we briefly discuss a solution for the 3-SAT problem in O(n*m) time. We also give the complete algorithm that can solve the n-queens completion problem in O(n...

The human mind is constituted by inner, subjective, private, first-person conscious experiences that cannot be measured with physical devices or observed from an external, objective, public, third-person perspective. The qualitative, phenomenal nature of conscious experiences also cannot be communicated to others in the form of a message composed o...

We report new theoretical and experimental results that may significantly change our ideas on the workings of life. We performed ab initio analysis of the band structure of periodic α-helix polypeptides (PP) in function of the chain length. Three different calculation approaches were tested: (a) PP described semiempirically as a one-dimensional obj...

Propagating waves, information transfers of direction of travel in collective groups, have been observed in animal groups of insects, birds, fish, and mammals. Nevertheless, although many previously proposed models of group behaviors have elucidated various aspects of collective motion, none has directly shown the propagating wave constructively. T...

In this paper we studied a resonate and fire relaxation oscillator subject to time dependent modulation to investigate phase-locking phenomena occurring in neurophysiological systems. The neural model (denoted LFHN) was obtained by linearization of the FitzHugh-Nagumo neural model near an hyperbolic fixed point and then by introducing an integrate-...

Shannon's channel coding theorem (1948), a major result of information theory, paradoxically states that errorless communication is possible using an unreliable channel. Since then, engineers developed many error-correcting codes and decoding algorithms. A performance close to the predicted one was eventually achieved no earlier than the beginning ...

The Standard Genetic Code (SGC) table was investigated with respect to the three-dimensional codon arrangement, and all possible 24 hierarchical base partitions (4! = 24). This was done by determining the amino acid scores for each codon hierarchy in relation to the 1st horizontal, 2nd vertical and 3rd horizontal sub-tables. Marked differences were...

Sonotopes are the acoustic patches of a soundscape, composed by different occurrences of geophonies, biophonies, and technophonies. According an ecosemiotic perspective, ecoacoustic events (EEs) are the vehicles from the attribution of meaning to the emergent sonotopes and work as neural codes. The process of encoding is suggested to be active betw...
