A theory of an electron affinity for an ionic cluster is proposed b.th in a quasiclassical approach and with quantization of a polarization electric field in a nanopartiele. A critical size of the cluster regarding in formation of an electron＇s autolocalized state, dependencies of energy and radius of a polaron on a cluster＇s size are ob.ained b. a variational method. It has b.en found that b.nding energy of the electron in the cluster depends on a eluster＇s radius b.t a radius of electron＇s auto-localization does not depend on the cluster＇s radius and it equals to the polaron radius in a corresponding infinity crystal. A b.und state of the electron in a cluster is possib.e only if the duster＇s radius is more than the polaron radius.

A simple model of the closely packed structure for system of hard-sphere particles interacting via the long-range Newtonian type attraction is suggested. b.sed on density functional theory, the exact equation of state is ob.ained and the mutual transformations of the crystal structures in such systems are studied. The description takes into account the fact impossib.lity of hard-sphere particles which have the same spatial occupation place.

The self-gravitating systems a priory are non-equilib.ium. The new approach, b.sed on non-equilib.ium statistical operator, which allows taking into account inhomogeneous distrib.tion of particles and temperature, has b.en proposed. Such method employs a saddle point procedure to find dominant contrib.tions to the partition function and permits to ob.ain all thermodynamic parameters of the system. Statistical induced dynamic and b.havioral peculiarities of self-gravitating systems for different conditions have b.en predicted.

The localized plastic flow auto-waves ob.erved for the stages of easy glide and linear work hardening in a numb.r of metals are considered. The propagation rates were determined expe- rimentally for the auto-waves in question with the aid of focused-image holography. The dispersion relation of quadratic form derived for localized plastic flow auto-waves and the dependencies of phase and group rates on wave numb.r are discussed. A detailed comparison of the quantitative characteristics of phase and group waves has revealed that the two types of wave are closely related. An invariant is introduced for localized plastic flow phenomena occurring on the micro-and macro-scale levels in the deforming solid.

A new approach is proposed to describ. the autowave processes responsib.e for plastic deformation localiza-tion in metals and alloys. The existence of a quasi-particle, which corresponds to a localized plastic flow autowave, is postulated and its characteristics are determined. The ab.ve postulate leads to a numb.r of cor-ollaries and quantitative assessments that are considered herein. The deformation processes occurring on the macro- and micro-scale levels are found to b. directly related.

The physical nature of the fundamental scalar field generation and hence the origination of the Universe is a matter of the discussions for many years. We propose to use the statistical approach to the description of the steady states of the quasi stationary systems with the elements of the quantum field theory methods as a b.sis to explain the appearance of the cosmological scalar field. Particularly, we apply two fundamental principles, i.e., the H-theorem and least-energy principle to show principal possib.lity of the scalar field origination. Along with the b.sic statement that in the presence of the fundamental scalar field, the energy of the vacuum ground state is lower than the ground state energy of the vacuum with no scalar field (primary vacuum), and with regard to the nonlinear interaction of fluctuating physical fields with the scalar field, these principles are employed to reveal prob.b.e phase transitions that may b. associated with origin and further evolution of the Universe. Thus, we propose the possib.e physical justification of the spontaneous cosmological scalar field generation.

b.ne marrow (b.) metastases are known to worsen the outcome in patients with malignancies and alter the choice of the treatment regimen. In an attempt to identify routine parameters for the prediction of b. metastasis we evaluated the clinical and lab.ratory data of 103 patients with metastatic solid tumors. We also assessed which of these factors appeared to influence survival. Three lab.ratory ab.ormalities were found to b. predictive of metastasis on b. b.opsy: thromb.cytopenia 9/L OR 14.4;p = 0.02;hypocellular or dry tap aspirate OR 7.0;p = 0.02 and high serum alkaline phosphatase OR 6.5;p = 0.03. Three additional factors were found to b. associated with deceased survival. Thromb.cytopenia was associated with decreased survival from a median of 0.8 months to 4.1 months, p levels more than twice the upper limit of normal were also reduced survival from 1.8 months versus 4.7 months, p = 0.03. Finally, the initial diagnosis of malignancy b. b.ne marrow examination was associated with reduced survival from 1.8 months vs. 4.0 months, p = 0.03 in individuals where b. metastases were not the presenting feature of malignancies. Use of these simple clinical parameters may help in the early diagnosis of b.ne marrow metastases and improve clinical approach.
