THE NANOSTRUCTURED MULTIPURPOSE BIOPOLYMERS AND NANOBIOCOMPOSITES ON THEIR BASIS FOR DIAGNOSTICS AND THERAPY
A novel original approach to self-organization of hybrid nanobiostructures possessing unique complex of physicochemical and biological properties (extremely demanded for noninvasive diagnosis and. therapy) is discussed
Обзор российских научных исследований в области права публичных финансов КНР
The article provides a systematic review of the scientific works of Russian legal scholars in the field of public finance law in China, in particular tax, budget and currency law. Today, it is premature to talk about fully functioning schools of Chinese law in the Russian legal science. However, at the same time there are examples of successfully conducted fundamental researches on Chinese public finance law. Authors have to admit that the last few years have not been marked by the appearance of any monograph on Chinese public finance law in Russia – the studies conducted today are usually devoted to specific problems and are published on the pages of the relevant journals. There are obvious reasons for this – difficulties in Chinese language learning and understanding specific Chinese legislation, which is characterized by uncertainty, ambiguity and plurality of sources of law. Existing studies can be classified into studies entirely devoted to the study of particular institutions or branches of Chinese law, and studies of a comparative nature. The article examines and systematizes the work of Soviet and Russian legal scholars devoted to various areas of research in the fields of tax, budget and currency law of China, with an assessment of their significance and contribution to the development of the relevant branch of knowledge. The materials in this article may be useful for future researches, which, in turn, can predetermine the strengthening of bilateral relations, as well as the implementation of joint investment projects. The article allows to identify unexplored areas in the considered field, thereby laying the foundation for future research. Authors note research issues that seem to be perspective based on the conducted review.Представлен системный обзор научных работ отечественных ученых-юристов, посвященных исследованиям в области правового регулирования публичных финансов в Китае, в частности налоговому, бюджетному и валютному праву. На сегодняшний день в отечественной правовой науке преждевременно говорить о сформированных и полноценно функционирующих школах изучения китайского права. Однако в то же время имеются примеры успешно проведенных фундаментальных исследований китайской отрасли публичных финансов. Обзорная статья позволяет определить неисследованные области в рассматриваемой сфере, тем самым заложив основу для будущих исследований. С учетом проведенного исследования авторы статьи отмечают отдельные вопросы, исследование которых представляется актуальным и перспективным
Quantum treatment of neutrino in background matter
Motivated by the need of elaboration of the quantum theory of the spin light
of neutrino in matter (), we have studied in more detail the exact
solutions of the Dirac equation for neutrinos moving in the background matter.
These exact neutrino wavefunctions form a basis for a rather powerful method of
investigation of different neutrino processes in matter, which is similar to
the Furry representation of quantum electrodynamics in external fields. Within
this method we also derive the corresponding Dirac equation for an electron
moving in matter and consider the electromagnetic radiation ("spin light of
electron in matter", ) that can be emitted by the electron in this case.Comment: 10 pages, in: Proceedings of QFEXT'05 (The Seventh Workshop on

First Order Static Excitation Potential: Scheme for Excitation Energies and Transition Moments
We present an approximation scheme for the calculation of the principal
excitation energies and transition moments of finite many-body systems. The
scheme is derived from a first order approximation to the self energy of a
recently proposed extended particle-hole Green's function. A hermitian
eigenvalue problem is encountered of the same size as the well-known Random
Phase Approximation (RPA). We find that it yields a size consistent description
of the excitation properties and removes an inconsistent treatment of the
ground state correlation by the RPA. By presenting a hermitian eigenvalue
problem the new scheme avoids the instabilities of the RPA and should be well
suited for large scale numerical calculations. These and additional properties
of the new approximation scheme are illuminated by a very simple exactly
solvable model.Comment: 15 pages revtex, 1 eps figure included, corrections in Eq. (A1) and

Ez-response as a monitor of a Baikal rift fault electrical resistivity: 3D modelling studies
3D numerical studies have shown that the vertical voltage above the Baikal deep-water fault is detectable and that respective transfer functions, Ez-responses, are sensitive to the electrical resistivity changes of the fault, i.e.
these functions appear actually informative with respect to the resistivity «breath» of the fault. It means that if the fault resistivity changed, conventional electromagnetic instruments would be able to detect this fact by measurement
of the vertical electric field, Ez, or the vertical electric voltage just above the fault as well as horizontal magnetic field on the shore. Other electromagnetic field components (Ex, Ey, Hz) do not seem to be sensitive to the resistivity changes in such a thin fault (as wide as 500 m). On the other hand, such changes are thought to
be able to indicate a change of a stress state in the earthquake preparation zone. Besides, the vertical profile at the bottom of Lake Baikal is suitable for electromagnetic monitoring of the fault electrical resistivity changes.
Altogether, the vertical voltage above the deep-water fault might be one of earthquake precursors
Systems of Hess-Appel'rot Type and Zhukovskii Property
We start with a review of a class of systems with invariant relations, so
called {\it systems of Hess--Appel'rot type} that generalizes the classical
Hess--Appel'rot rigid body case. The systems of Hess-Appel'rot type carry an
interesting combination of both integrable and non-integrable properties.
Further, following integrable line, we study partial reductions and systems
having what we call the {\it Zhukovskii property}: these are Hamiltonian
systems with invariant relations, such that partially reduced systems are
completely integrable. We prove that the Zhukovskii property is a quite general
characteristic of systems of Hess-Appel'rote type. The partial reduction
neglects the most interesting and challenging part of the dynamics of the
systems of Hess-Appel'rot type - the non-integrable part, some analysis of
which may be seen as a reconstruction problem. We show that an integrable
system, the magnetic pendulum on the oriented Grassmannian has
natural interpretation within Zhukovskii property and it is equivalent to a
partial reduction of certain system of Hess-Appel'rot type. We perform a
classical and an algebro-geometric integration of the system, as an example of
an isoholomorphic system. The paper presents a lot of examples of systems of
Hess-Appel'rot type, giving an additional argument in favor of further study of
this class of systems.Comment: 42 page
