К обобщенной релятивистской кинетической и гидродинамической теории
No full textOn the basis of statistical description the movement of relativistic particles without external forces is considered. The hydrodynamic form of the Dirac equation is suggested. The Lorentz invariant form of the non-local Alexeev equation (generalized Boltzmann equation) was obtained. These results lead to the possibility of construction of relativistic quantum hydrodynamics. This paper can also be considered as continuation of the known monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004).На основе статистического описания рассматривается движение релятивистских частиц без учета внешних сил. Представлена гидродинамическая форма уравнения Дирака. Получена лоренц-инвариантная форма нелокального кинетического уравнения Алексеева (обобщенного уравнения Больцмана), что открывает возможность построения обобщенной релятивистской квантовой гидродинамики. Статья может также рассматриваться как продолжение исследований, изложенных в известной монографии. (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004)
Income Distribution and Price Controls: Targeting a Social Safety Net During Economic Transition
No full textDuring the ongoing post-communist economic transitions, the relative well-being of many people is changing rapidly, and governments are not well positioned to accurately measure individual living standards. Under such circumstances, continued price controls over basic consumer goods within the state sector, and the associated queuing, can form a serviceable device for targeting poor people for subsidies. With a fixed-price state sector and free-price parallel markets, rich people might choose to avoid queues and shop in the free markets, while poor people would prefer to pay low nominal prices and queue in the state sector. The targeting of subsidies through queues, therefore, can be accomplished even if the government has no information on individual income or living standards. When the alternative to price controls is a poorly targeted explicit social safety net, the resource cost of queues might be more than compensated for by an improvement in the targeting of subsidies.price controls, tax evasion, queue-rationing, economic transition, income distribution

ASYMPTOTIC DISTRIBUTION OF SINGULAR VALUES OF POWERS OF RANDOM MATRICES
No full textAlexeev N, Götze F, Tikhomirov A. ASYMPTOTIC DISTRIBUTION OF SINGULAR VALUES OF POWERS OF RANDOM MATRICES. LITHUANIAN MATHEMATICAL JOURNAL. 2010;50(2):121-132.Let x be a complex random variable such that Ex = 0, E|x|(2) = 1, and E|x|(4) infinity EFN(m)(x) of the empirical distribution function F-N((m))(x) = N-1 Sigma(N)(k=1) I{lambda(k) <= x}, where I {A} stands for the indicator function of an event A. With m = 1, our result turns to a well- known result of Marchenko and Pastur [V. Marchenko and L. Pastur, The eigenvalue distribution in some ensembles of random matrices, Math. USSR Sb., 1:457- 483, 1967]
A simple laser beam characterization apparatus based on imaging
No full textThe development of an original low-cost hardware/software apparatus to optically control the laser beam and measure quality parameters by image analysis using a monochrome matrix sensor is described, along with experimental validation. Laser parameters, namely beam waist, divergence, Rayleigh range and M2, which are the most relevant in manufacturing operations (like optical measurement and laser processing), have been physically and mathematically characterized. Strategies for the apparatus size reduction are also presented, including the use of a prism to reduce by half the optical path, and a camera model to simulate the sensor resolution
Comment on "Radiation History of Fossil Meteorites from Sweden" by V.A. Alexeev (2010), Solar System Research, 44, 311-319
No full textWe dispute the claim by Alexeev (2010) that the numerous fossil meteorites found in mid-Ordovician sediments in southern Sweden can be explained by a single large meteorite shower some 470 million years ago, and-in particular-that the reported variable cosmic ray exposure ages derived from cosmogenic Ne-21 in chromite grains extracted from the fossil meteorites actually reflect variable contributions of nucleogenic Ne-21 instead
Обобщенная квантовая гидродинамика
No full textThis paper addresses the fundamental principles of generalized Boltzmann physical kinetics, as a part of non-local physics. It is shown that the theory of transport processes (including quantum mechanics) can be considered in the frame of unified theory based on the non-local physical description. The paper can be considered also as comments and prolongation of the materials published in the known author’s monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004).В статье рассматриваются фундаментальные принципы обобщенной Больцмановской физической кинетики как составной части нелокальной физики. Установлено, что теория процессов переноса (включая квантовую механику) может быть рассмотрена в рамках универсальной теории, основанной на нелокальном физическом описании. Статья может рассматриваться как продолжение исследований, опубликованных в известной монографии автора (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004)
