Bioethics: Reincarnation of Natural Philosophy in Modern Science
The theory of evolution of complex and comprising of human systems and algorithm for its
constructing are the synthesis of evolutionary epistemology, philosophical anthropology and
concrete scientific empirical basis in modern (transdisciplinary) science. «Trans-disciplinary» in
the context is interpreted as a completely new epistemological situation, which is fraught with the
initiation of a civilizational crisis. Philosophy and ideology of technogenic civilization is based on
the possibility of unambiguous demarcation of public value and descriptive scientific discourses
(1), and the object and subject of the cognitive process (2). Both of these attributes are no longer
valid. For mass, everyday consciousness and institutional philosophical tradition it is intuitively
obvious that having the ability to control the evolutionary process, Homo sapiens came close to the
borders of their own biological and cultural identity. The spontaneous coevolutionary process of
interaction between the «subject» (rational living organisms) and the «object» (material world), is
the teleological trend of the movement towards the complete rationalization of the World as It Is,
its merger with the World of Due. The stratification of the global evolutionary process into selective
and semantic (teleological) coevolutionary and therefore ontologically inseparable components
follows. With the entry of anthropogenic civilization into the stage of the information society, firsty,
the post-academic phase of the historical evolution of scientific rationality began, the attributes of
which are the specific methodology of scientific knowledge, scientific ethos and ontology. Bioethics
as a phenomenon of intellectual culture represents a natural philosophical core of modern post-
academic (human-dimensional) science, in which the ethical neutrality of scientific theory
principle is inapplicable, and elements of public-axiological and scientific-descriptive discourses
are integrated into a single logic construction. As result, hermeneutics precedes epistemology not
only methodologically, but also meaningfully, and natural philosophy is regaining the status of the
backbone of the theory of evolution – in an explicit for
Renormalization group in the infinite-dimensional turbulence: third-order results
The field theoretic renormalization group is applied to the stochastic
Navier-Stokes equation with the stirring force correlator of the form
k^(4-d-2\epsilon) in the d-dimensional space, in connection with the problem of
construction of the 1/d expansion for the fully developed fluid turbulence
beyond the scope of the standard epsilon expansion. It is shown that in the
large-d limit the number of the Feynman diagrams for the Green function (linear
response function) decreases drastically, and the technique of their analytical
calculation is developed. The main ingredients of the renormalization group
approach -- the renormalization constant, beta function and the ultraviolet
correction exponent omega, are calculated to order epsilon^3 (three-loop
approximation). The two-point velocity-velocity correlation function, the
Kolmogorov constant C_K in the spectrum of turbulent energy and the
inertial-range skewness factor S are calculated in the large-d limit to third
order of the epsilon expansion. Surprisingly enough, our results for C_K are in
a reasonable agreement with the existing experimental estimates.Comment: 30 pages with EPS figure
Theory of friction: contribution from fluctuating electromagnetic field
We calculate the friction force between two semi-infinite solids in relative
parallel motion (velocity ), and separated by a vacuum gap of width . The
friction force result from coupling via a fluctuating electromagnetic field,
and can be considered as the dissipative part of the van der Waals interaction.
We consider the dependence of the friction force on the temperature , and
present a detailed discussion of the limiting cases of small and large and

Anomalous scaling of a passive scalar advected by the Navier--Stokes velocity field: Two-loop approximation
The field theoretic renormalization group and operator product expansion are
applied to the model of a passive scalar quantity advected by a non-Gaussian
velocity field with finite correlation time. The velocity is governed by the
Navier--Stokes equation, subject to an external random stirring force with the
correlation function . It is shown that
the scalar field is intermittent already for small , its structure
functions display anomalous scaling behavior, and the corresponding exponents
can be systematically calculated as series in . The practical
calculation is accomplished to order (two-loop approximation),
including anisotropic sectors. Like for the well-known Kraichnan's rapid-change
model, the anomalous scaling results from the existence in the model of
composite fields (operators) with negative scaling dimensions, identified with
the anomalous exponents. Thus the mechanism of the origin of anomalous scaling
appears similar for the Gaussian model with zero correlation time and
non-Gaussian model with finite correlation time. It should be emphasized that,
in contrast to Gaussian velocity ensembles with finite correlation time, the
model and the perturbation theory discussed here are manifestly Galilean
covariant. The relevance of these results for the real passive advection,
comparison with the Gaussian models and experiments are briefly discussed.Comment: 25 pages, 1 figur
