'Natural' is difficult to define formally in a mathematical model. For a model is an artificial construct relying on reduced conditions and assumptions. A model gives rise to weak anticipation while strong anticipation requires us to raise our sights to metaphysics where naturality resides. A prime distinction is that metaphysics has a higher-order tense logic. Strong anticipation is no prisoner of time like weak anticipation. In general while adjointness has a logical ordering the operation of an environment C on a subobject A has a solution subobject B under Heyting inference A ⇒ B in the environment of C. This is represented as the expression C x A ⟶ B ┤ BA ⟵ C, the adjunction of the natural metaphysical ordering which constitutes strong anticipation. The environment C may be more particularised as an adjunction between the induced monad and comonad functors. The uniqueness of the adjunction in natural metaphysics is examined in the context of the Beck-Chevalley test for computing the multiplicity of formal models possible for weak anticipation.

This article gives an overview of the most characteristic steps of the relational modeling strategy, from the component to augmented abstract block diagrams, putting the emphasis on some epistemological aspects. Robert Rosen's modeling strategy is a formal representation of biological organization, specifically of circular causality. In this regard, the most important contribution of Robert Rosen is the anschaulichkeit - the intuitability - of the closure of the organization and of the intertwinement of the different Aristotelian causes, even if they are incommensurable.

In order to make this interface intelligible, the conditions under which community ideals (policy) and group ideals (civility) become possible, need to be revealed from an engaged position that allows for questioning and exploring what it means to be a citizenship expert.

The "Anticipations" determine the ability of the understanding to anticipate phaenomena in their matter, i.e. not in that which concerns their form, but in that which is empirical, in that which concems sensation. What is so startling here, is that precisely in sensation, where the subject seems to be passively subjected to the contingency of a material reality, there is a minimal form of anticipation, a form of a priori knowledge. Hereby, the standard 'Kantian' disctinction between a priori and a posteriori, between transcendental form and empirical matter, is, for a moment, collapsed. In the present paper, I hope to show how this principle accounts for the necessarily problematic status of the origin in transcendental philosophy.

Kant, and especially Fichte, derive from this proof (by way of a reduction ad absurdum) that all forms of thinking presuppose the principle of identity, opposition and limitation. As a consequence, this means that anticipation, as a form of thinking, must presuppose all three principles. How do these three principles, concerning anticipation, function?

Time is, as any transcendental concept, regarded as basically relational and subjective and only in a derivative way objective and indifferent to us. This entails that memory is prior to history, and that anticipation is prior to prediction. In this paper, I will give some examples in order to argue for this point. Furthernore, I will also argue, again with Cassirer and contra Henri Bergson, that time should be seen as a functional unity, and not as a collection of three different things-in-themselves (past, present and future).

Particular attention is given to the finiteness of the subject, the notion of teleology, Kant's peculiar account of pure interest and the way in which these notions are interwoven. This serves to clarify the peculiar status of anticipation as a primarily subjective activity, based on finiteness and subjective engagement. Furthermore, an attempt is made to gain insight in the way a subject capable of anticipation is structured and the way it is related to its own structure.

However, functional explanation remains one of the most controversial issues in philosophy of biology : two main philosophical approaches address biological functions from disparate views. In this paper, I sketch out how neither etiological approaches nor systemic approaches pay enough attention to functional explanation as used in biological practice. I suggest that a detailed comparison of mechanisms in both accounts may be fruitful in identifying common problems and suitable solutions.

Transitional objects, phenomena and processes belong neither to the inside nor to the outside : they are interfaces which partake in both but are of an ephemeral nature. However, their meaning and function survive as internalized structures. When this happens strong anticipation governs, as the system has internalized a model of the potential space between inside and outside and is able to experience a shared reality as a true individual.

We introduce a Time Operator, and discuss its role in self-control, chronomes, will and a third-order time derivative. We apply the theory to visual perception and the problem of brain hemisphere integration for stereoscopic vision and its relations to micro and macroscopic non-local entanglement, torsion vortices and anticipation.

It is not the case of topology, although behind the phenomenon of continuity always a topology must be understood. In a continuous process, if two possible causes remain close, that is in a certain neighborhood, they will produce close effects. The set of possible causes which lead to a studied effect is organized as a topological space. Researchers can deal with metric spaces, with norms or semi-norms, but it is important to establish the notion of neighborhood, or to define a system of open sets. In the study of dynamic systems with infinite memory a locally convex topology was introduced. The present paper reviewed results obtained when the inputs were continuous and indefinite derivable functions from minus infinite to the present moment, then it pass to the case when the inputs are known only as rows of values. In the last part the informational topology is exposed.

This paper proposes an approach for modelling Human-Organisation-Environment lead by the safety point of view. Our perspective is that the propulsion system needs to exhibit some aptitudes at each step of the mission. Its structure must be able to evolve in front of some unforeseen situations during the flight. Before and during the design stage, different paths of modeling are possible. Our paper proposes a new approach for modeling that allows to merge different hypothesis in link with a subjective approach for risks. Cooperation is required at the early stage of the project and the quality of the result is fundamentally inseparable from the problem formulation perceived from different points of view.

But it is still a hard sell in practice. This is a fact gathered through engineering experience. When the effect of the prior washes off quickly, the issue is irrelevant and one enjoys the probabilistic updating algorithm. When there is little data, one seriously questions the validity of the Bayesian approach. Very little has been achieved in developing means to support the existence of a prior, assess it and calibrate the person providing the opinion. We review the theory and show a case in bridge maintenance where the likelihood of the expert can be assessed. We state the reason for its inapplicability, take a step back to the days of Kolmogorov and reflect on Bayesian theory.

We develop a category theoretical treatment of directed networks in order to obtain functional networks for real networks. By applying our method to concrete data on real information processing biological networks, we find a distinguishing global structure of functional networks. A possibility of a new hypothesis on network motifs is also indicated based on our theory and data analvsis.

In the communication (Nibart & Dubois, 2008) we have deduced several properties of the presence density of non-dimensionless particles and proposed some applications to Cosmology. In the present paper, we propose a solution to the dark matter problem, an explanation of the presence of antimatter in the Universe and we sketch a new concept of vacuum based on extremely high Bessel orders at the cosmological scale.

These outcomes apparently disagree both with standard quantum mechanics (Copenhagen interpretation) and with classical and quantum electrodynamics. Possible interpretations can be given in terms of either the existence of de Broglie-Bohm pilot waves associated to photons, and/or the breakdown of local Lorentz invariance (LLI). We put forward an intriguing hypothesis about the possible connection between these seemingly unrelated points of view by assuming that the pilot wave of a photon is, in the framework of LLI breakdown, a local deformation of the flat minkowskian spacetime.

The solution of the problem is reduced to the decomposition of a singly scattered light correlation function into the sum of exponential functions. The optical method of the sizing based not on single, but multiple scattering just elaborated is described. Correlation times obtained by the fiber probe allow us to obtain the averaged value of the particle size. But the problem is to obtain the size distribution from the correlation function of multiply scattered light. An example of result of analysis of correlation function of light multiply scattered by bimodal suspension is represented. Several questions have been asked to mathematicians as a conclusion.

This Island was theoretical predicted in the seventies to be situated around Z=ll4 and N=184. The fusion cross sections in reactions with 48Ca on heavy targets are of the order of the pico barn, it means a few months of experiment for few events, in the normal experiments with the actual accelerators intensities and targets. New ideas can be proposed : collision between two heavy nuclei with high spin ground state or the combination of the heavy nuclei with high spin isomer. These high spins states can stabilise the double nuclear system and rise the chance to go into fusion. We suggest to use the advantage of High Spin Isomer States, by taking into account the importance of the quantum number G (spin – isospin coupling) suggested by Ripka (2008). The 178Hf 2m (2m means second isomer, I=16h, 3l years life time) is an interesting nucleus. In this article we propose to use this isomer as a target (projectile) for production of SHE. More, we suggest other high spin targets projectile combination like : 117Sn(I=11/2 , 14d) + 176Lu (I=7 , 38Gy) → 293121 Mon, 14 Oct 2024 16:03:52 +0200 http://popups.lib.uliege.be/1373-5411/index.php?id=4668 http://popups.lib.uliege.be/1373-5411/index.php?id=4673 The different concepts of "space" are contrasted which have been developed in mathematics and in physics. Early proposals of extra dimensions are briefly reviewed. The main thesis claims that in physics not the dimension number of the underlying space is essential ; rather, there are strong reasons to use vector spaces over the field of complex numbers, not strictly excluding other structures. Reasons for this come both from mathematical rigour and from human cognition. Applications to physics concern nonlocal processes, conditions for quantum entanglement, and a proposal of hidden organizing structures. An experimental test for nonlocal hidden structures is proposed.

E.g., speed is LT-1, force is MLT-2 and so on. However, Saumont has observed that it is no rational to give dimensions to constant quantity and not to give dimensions to variable quantity. Also, standard dimension analysis implies an evident hyper-cubic topology MnLpTpQrΘs that isn't incompatible with (hyper)incursive systems that have hypersphere or torus topology. Finally, Grappone has proven that anticipatory systems, in terms of set inclusive networks, are equivalent to first order theories in mathematical logic, i.e. polyadic or cilindric algebras that haven't a simple hypercubic structure. This paper is an attempt to start the solving of these problems.

The four elements : p↑, p↓, n↑, n↓ are bound in a chain, a close loop. With this model we succeeded to explain nuclear phenomena like : alpha radioactivity, fission or fusion. Our present work goes further by considering the quark (anti quark) structure of the nucleons : protons, neutrons, or of the quanta (quark antiquark) of the nuclear field interaction : the pion. We suggest that the atomic nucleus is a loop chain of the quarks (real or virtual antiquark).

On another side we have the new scientific directions – cybernetics, system analysis, synergetics and informatics, which used for study of complex systems in biology, economics and technics, and naturally to try to consider Universe how complex system and to use the accumulated arsenal of instruments of investigation of self-organizational system. This report is the attempt in this direction. We examine the linguo-combinatorial simulation of solar system, where used how key words the names of planets, and detect the structural uncertainty in equivalent equations systems, which can used for adaptation in flow of changes. The constructed self-organized system is the basic building block, which can create collective on different levels – planetary, galactic, etc. Star clusters are the basic blocks for creation of equivalent equations with structural uncertainty, which can use for stabilization of systems. Today the understanding of asteroid hazard for mankind is confirmed by means of big amount of experimental facts and theoretical simulation results. The size of asteroids increase the degree of danger, it is obviously impossibility of catastrophe for big asteroids if we will be stay on old scientific paradigm. In this paper we try to search the way from dangerous situation on basement of linguo-combinatorial simulation of complex planet systems. If we shall take the key words - Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto - 10 variables, we shall have the equivalent equations with 45 arbitrary coefficients. In this equations system A1 – characteristics of Sun, E1 - variation of this characteristics, A2 – characteristics of Mercury, E2 – variation of this characteristics, …, U1, U2,… , U45 – arbitrary coefficients, which permit to control of characteristics. The discovery of this new possibility is very important for mankind in view of asteroids hazard. Big hope is the discovery of new methods for planet processes control. For stability the sun system must be in the adaptation maximum zone.
