Is Semantics Physical?!
It is demonstrated that under the hypothesis of boundedness, the semantics
appears as a property of spontaneous physical processes. It turns that both
semantic structure and semantic meaning have their own physical agents each of
which is represented trough generic for the state space property. The
boundedness sets an exclusive two-fold representation of a semantic unit: as a
specific sequence of letters and as a performance of a specific engine so that
their interplay serves as grounds for building a multi-layer hierarchy of
semantic structures. It is established that in this setting the semantics
admits both non-extensivity, permutation sensitivity and Zipf`s law. The
robustness of the hierarchical organization of semantic structures is
maintained by new generic form of non-local feedback that appears as a result
of the necessary for sustaining boundeness matter wave emitting.Comment: 11 pp, no fi
Self-Organization and Finite Velocity of Transmitting Substance and Energy through Space-Time
The idea that the velocity of transmitting substance/energy trough space-time
is to be bounded is a fundamental concept in the science. To the most surprise,
it turns out that it is not always met. We demonstrate that the existing
approaches to the self-organization, another major concept in the science, let
the velocity of transmitting substance to be arbitrary. Further we prove that
only the boundedness of the velocity is not enough to ensure the
self-organization. That is why we develop radically novel approach to the
macroscopic evolution that not only reconciles the self-organization and the
velocity ansatz but in addition gives physically credible basis to phenomena
like Feigenbaum cascade and fluctuation-assisted bifurcations.Comment: 10 pages, no figure
Coarse-Grained Structure of a Physical (Strange) Attractor. Analytical Solution
The structure of the physical and strange attractors is inherently associated
with the boundedness of fluctuations. The idea behind the boundedness is that a
stable long-term evolution of any natural and engineered system is possible if
and only if the fluctuations that the system exerts are bounded so that the
system permanently stays within its thresholds of stability. It has been
established that the asymptotic structure of the physical and strange
attractors is identical. Now it is found out that though the non-asymptotic
behavior is universal it can be very different, namely: on coarse-graining the
physical attractors can exhibit a variety of behavior while the strange
attractors always have hyperuniversal properties. Yet, under certain levels of
coarse-graining both physical and strange attractors match non-asymptotically a
variety of noise type behavior.Comment: 7 pages, presented at 5-th Int. Conference "Symmetry in Non-Linear

Boundedness in Complex Systems: New Approach to Power Law Distributions
A new approach to complex systems aimed to resolve their paradoxes is
proposed. Yet, the major inference is the prohibition of informational

Stochastic Thermodynamics and Dynamics: A Tail of Unexpected
The problem of the insensitivity of the macroscopic behavior of any
thermodynamical system to partitioning generates a bias between the
reproducibility of its macroscopic behavior viewed as the simplest form of
causality and its long-term stability. The overcoming of this controversy goes
through certain modification of the dynamics that involves self-assembling of
the boundary conditions. Subsequently the proposed approach justifies parity
between the increase and the decrease of the entropy which provides the ground
for holistic understanding of the thermodynamical systems through launching
their ability to transmit and create information that is sensitive to coherent
functioning of self-assembled logical landscapes. The obtained sensitivity
gives the advantage of this new approach compared to that of Shannon. According
to his definition, the information depends only on the overall probability for
realization of a given state(s) and thus it does not distinguish between
functionally different states provided the overall probability for the
realization of each of them is equal.Comment: 7 pages, novel approach to the securiiy of encrypting that comes out

Sustainable Evolution in an Ever-Changing Environment: General Characterization
A complex interplay between the academic issue about generalization of the
thermodynamics and the practical matter about setting standards for a
sustainable evolution of both tailored devices and natural systems is
considered. It is established that the measure for a sustainable evolution in
an ever-changing environment appears as a Boltzmann-Gibbs weight. At the same
time, this measure performs as a local thermodynamical potential which, at the
expense of being released from the condition of entropy maximization, serves as
grounds for a fundamental development of the idea of banning perpetuum mobile.
It is proven that the best efficiency of each engine that operates reversibly
never exceeds the efficiency of corresponding Carnot heat engine where the
engine is free from necessity of a physical coupling to two heat reservoirs.Comment: 10 pages, 1 figur
Size-Independent Non-Equilibrium Fluctuations
A local quantum phenomenon that gives rise to generic for all surface
reactions macroscopic fluctuations is studied. The issue is viewed with respect
to the necessary conditions for a long-term stable evolution of any natural and
artificial system. It is shown that global coupling of the local fluctuations
is necessary for providing a long-term stability of the system. A successful
coupling mechanism is achieved on the grounds of new assumptions about the
Hamiltonian response to certain perturbations. The coupling mechanism acts
towards a global synchronisation, i.e. to a coherent response of the excited
species to any further perturbation. It is proven that the synchronisation is a
scale-free process that has universal properties, e.g. it is insensitive to the
chemical identity of the reacting species and to the particularities of the
surface reaction. Its hallmark is that the global adsorption rate exhibits
permanent temporal variations whose amplitude is independent of the system
size.
The presence of these fluctuations fundamentally changes the temporal
behavior of the system, namely it becomes pulse-like both on the quantum and
the macro-level. The pulse-like behavior gives rise to a persistent continuous
band at the quantum spectra whose major properties are: (I) it does not
correspond to any real radiation; (ii) its presence is insensitive to the
particularities of the system and the incident radiation; (iii) its shape and
the infrared edge are typical for the -type noise. These properties give rise
to its name: alias -type noise.Comment: 22 pages, major revisio
Modelling of Desorption from Small Metal Clusters
It is found out that there are physical effects, typical of small metal
clusters deposited on a non-adsorbing support, that cause a difference between
the adsorption properties of sites at the metal cluster surface and those of
sites at the boundary of metal-support. This difference gives rise to an extra
band in the IR spectra of the adsorbate whose major property is that its
intensity changes with cluster size.
The migration of chemisorbed molecules (atoms, ions) and molecules (atoms,
ions) in any excited state over adsorption sites of different type results in
changes in the state of the molecule (atom, ion) since the latter adjusts its
state to the set of levels of another type of site. This can be described
figuratively as a transformation of the type of adsorption site. Thus, a single
type of adsorption site, called next surface effective site (SES), is formed.
The energy of desorption from SES site retains an explicit dependence on the
metal cluster size. A simulation of TPD spectra of oxygen desorption from small
Pt clusters deposited on NaX zeolite was carried out. A comparison to
experimental TPD spectra obtained by Jaeger and co-workers for the same system
is made.Comment: 8 pages, 7 figure

Boundedness and Self-Organized Semantics: on the Best Survvival Strategy in an Ever-Changing Environment
General criterion for best efficiency of the interaction of a complex system
with an ever-changing environment is derived. Its exclusive property, set by
boundedness, is that the highly non-trivial interplay between parameters that
participate in it renders the best survival strategy to go via non-extensive
hierarchical super-structuring of the semantic-like response.Comment: 14 pages, no figure
