Its first general formulation dates back to the 70s, and its development is now increasing, with recent great successes digging deeply into biosystem structure-function, with near- future plans and the present capital investments. Ecological and ethical problems have been raised that might delay such plans, and in spite of its successes, Synthetic Biology and its branch Synthetic Life that aims at recreating life itself, both as an extreme engineering effort whose enabling technologies stem from biosystem Nanophysics and Nanoengineering, lack the background for realization of their most advanced purposes: attaining the ability to nanoengineer biological members as genes, genomes, subcellular members, cells and tissues, up to recreating life in the lab through ab initio processes.

The problem is how does it work? It is proposed that frequency is the language of bio- computing activity and that these frequencies are coherent to the theoretical limit. Frequency has a duality with chemical structure and as an expression of energy level change it can provide a control function. All bio-systems are water based and can use the coherent properties of water to implement basic arithmetic operations and basic reversible logic gates. Strong anticipation is imbedded chemically in nucleotides, chemicals and their frequency signatures and water memory. Weak anticipation derives from a need for future chemicals and activities predicted from within a self-model.

The relationship is an adjointness between levels, requiring contravariancy. The intension/extension levels are impredicative in nature but this recursive characteristic can be represented formally in category theory. This paper focuses on the vital role of contravariancy in adjointness, permitting a structured re-ordering of the categories involved. A worked example of a three-level architecture for an information system is provided, illustrating the alternation of intension/extension pairs, the adjointness of two-way functors between each level, the (bi)functors for linking intension to extension and the locally cartesian closed structure of the underlying categories. The dynamic anticipatory aspect of contravariant mapping, relative to static covariant mapping, is highlighted, reinforcing the view that contravariancy underpins anticipation.

Entropy and information can be shown to have a direct connection with the concept of the generation of the number field at a very fundamental level.

In particular, the evidence of Scully et al taken together with that of Schempp, presented over several years, shows how the usual objection to quantum coherence, that the brain is a thermodynamic hot machine, can be and are overcome, as is indeed would appear to be the case for the photosynthetic harvesting of photons by chlorophyll.

Mathematics emerges from the system in the form of a Clifford-type algebra, while physics takes the form of nilpotent quantum mechanics (NQM). The most significant characteristic of NQM is that the quantum system (fermion state) and its environment (vacuum) are mathematical mirror images of each other. So a change in one automatically leads to corresponding changes in the other. We have used this characteristic as a model for self-organization, which has applications well beyond quantum physics. The nilpotent structure, seen as emerging from two commutative vector spaces, has a number of identifiable characteristics which we can expect to find in systems where self-organization is dominant; a recent case involves the neurons in the visual cortex. We expect to find many complex systems where our general principles, based, by analogy, on NQM, will apply.

The model implicates the use of spacetime algebra to describe Minkowski space on large scales, but suggests that its scale independent use in special relativity presupposes reference frames of infinite mass. A close look at the finite-frequency digital clock shows that either classical special relativity or Dirac propagation emerges from the clock depending on how the continuum limit is taken. If one smoothly interpolates the tick sequence the clock remains classical. If one extrapolates the inter-tick behaviour, wave propagation is implicated.

Crucial applications of the conformal steady-state free-precession modality and automorphic scattering theory are the compelling evidence for a supermassive central black hole in the Milky Way galaxy.

New insights in understanding many Nucleus properties like limit of stability are obtained. BE generalized to the structured objects give some hints to find origin of the missing mass (dark matter). The very new CHAIN Model of the nucleus is confronted with the classical mass formula. Some ideas for studies of Super Heavy Elements (SHE) related to the role of high spin states and their importance in binding energy calculation are presented.

The causality is defined without invoking the time relation. It clarifies Cramer principle of weak causality, which admits time reversal in the entangled states and directly leads to the anticipation. The quantitative quantum measure of causality is the pseudoscalar velocity of irreversible information flow called the course of time. The smaller course of time modulus, the stronger causal connection. The causal parameters for the examples of three-qubit entangled states have been computed. The results have been compared with the degrees of mixedness and entanglement of the states. In the simplest cases the formal measure of quantum causality does not contradict its intuitive understanding. But even in slightly more complicated situations intuition may be a failure.

The problem in this paper is to derive the generalized metrics in the Relativistic Alpha Field Theory (RAFT). In that sense, it is started with the new General Lorentz Transformation model in an alpha field (GLTα - model) derived by employing the well known group postulates and isotropy of the space. It follows the derivation of the general line element and the related general metric tensor in an alpha field both in the Minkowski and Riemannian metrics. The one section of the paper is devoted to derivation of a general diagonal form of a line element and metric tensor in an alpha field. It has been shown that there exists a simple coordinate transformation procedure in an alpha field that transforms the Riemannian metrics into the Minkowski one and vice versa.

Locality and nonlocality are fundamental components of a dual system in which each determines the behaviour of the other. The exact characteristics of the different local interactions (weak, strong and electric) can be shown to be completely determined by the nonlocal vacuum structures with which they are associated. At the same time, gravity provides a nonlocal dual to the combined interactions, which has inertia as its local manifestation. A completely integrated description of local interactions and nonlocal vacuum structures is proposed, based on nilpotent quantum mechanics and its unique algebraic structure.

The spacetime area is conserved, as well, if only the space dimension parallel to the field is taken into account. The latter property leads to an intuitive account of geodesic motion. Starting from the so-called Rindler hyperbolae, which describe constant proper acceleration in special relativity, the coordinate transformations for the equivalent homogeneous gravitational field are developed and applied to some elementary gravitational scenarios. The geodesic equations of planar fields are analyzed and compared for the two cases of volume conserving metrics and "isotropic" metrics conserving spacetime areas. An isotropic counterpart of the Schwarzschild metric is given by Broekaert's "scalar gravitation model", which is shortly discussed.

Two different microscopic approaches to the study of the photon delay caused by a gravitating body are examined: the variational procedure of classical mathematics and the fractal changes of the fundamental tessel- lattice of space. It is shown that only the second approach brings about a reasonable alteration to the photon path consistent with the experimental result. Namely, the gravitating body contracts cells of space and hence photons hopping from cell to cell run through a larger number of cells, which results in a lengthening of the whole photon path.

The requirements of time order and operator self-adjointness are too much restrictive. To describe quantum correlations of N particles with a possible not causal order we propose a new formalism which include all conjugate quantities in the same configuration space where we define a "global state function" Ψ of 6N+1 scalar variables. The function Ψ is 3N-dimensional (non relativist Ψ) or 4N-dimensional (relativist Ψ) when spin variables are separable. Usual kinematic functions are computed as implicit functions, and new quantum operators are introduced.
