Norm minimized Scattering Data from Intensity Spectra

We apply the $l_1$ minimizing technique of compressive sensing (CS) to non-linear quadratic observations. For the example of coherent X-ray scattering we provide the formulae for a Kalman filter approach to quadratic CS and show how to reconstruct the scattering data from their spatial intensity distribution.Comment: 26 pages, 10 figures, reordered section

Developmental changes of primary processes of photosynthesis in sun- and shade-adapted berries of two grapevine cultivars

Light utilisation and thermal dissipation of field-grown sun- and shade-adapted berries of cvs Kerner (white) and Portugieser (red) were investigated during berry development by determining chlorophyll fluorescence parameters. In stages I and H of berry development for both cultivars the maximum quantum yield of photochemical energy conversion of dark-adapted berries (Fv/Fm) was close to the maximum (0.75-0.80). It decreased significantly in sun- and shade-adapted berries of cv. Kerner two weeks after veraison indicating damage of photosystem 11 (PSII) during ripening. When at veraison anthocyanins accumulated in the skin of berries chlorophyll fluorescence of cv. Portugieser berries could no longer be determined. In both cultivars the linear electron transport rate at light saturation (ETRmax) increased in stage I and reached maxima in stage 11, sun-adapted berries showing higher rates than shade-adapted. After high values in stage I non-photochemical quenching at light saturation (NPQmax) decreased in light- and shade-adapted Kerner berries in stage 11 indicating a lowering of the thermal dissipation efficiency. The pool size of the xanthophyll cycle pigments diverged significantly in sun- and shade-adapted berries during their development: under clear, warm and dry weather conditions in shade-adapted berries the xanthophyll pool size decreased to low levels, while in sun-adapted berries it increased to maximum values shortly before (cultivar Kerner) or at veraison (cultivar Portugieser) and subsequently declined. Unripe, sun-adapted berries of both cultivars showed a transient decline of the xanthophyll pool size during a rain period suggesting pool size adjustment to changes of ambient conditions in the longer term. It is concluded that unripe, sun-adapted berries are better adapted to high light than shade-adapted berries due to their higher capacity of photosynthetic energy consumption and thermal energy dissipation; at the onset of ripening these photoprotective mechanisms appear to loose importance.

THE MEANS OF SPECIAL ORIENTATION OF CHILDREN WITH VISUAL IMPAIRMENTS IN FAMILY EDUCATION CONDITIONS

In the article the main directions, theoretical-practical ways of development of spatial orientation of preschool children with visual development, and its necessity in family education conditions are presented. The aim of the research is to elaborate means, methods and conditions of their application for development of the ability of the spatial orientation of preschool children with visual impairments in family settings. To provide parents with visual knowledge is the result of implemented works.In the article the main directions, theoretical-practical ways of development of spatial orientation of preschool children with visual development, and its necessity in family education conditions are presented.

Wightman function and Casimir densities for Robin plates in the Fulling-Rindler vacuum

Wightman function, the vacuum expectation values of the field square and the energy-momentum tensor are investigated for a massive scalar field with an arbitrary curvature coupling parameter in the region between two infinite parallel plates moving by uniform proper acceleration. We assume that the field is prepared in the Fulling-Rindler vacuum state and satisfies Robin boundary conditions on the plates. The mode-summation method is used with a combination of a variant of the generalized Abel-Plana formula. This allows to extract manifestly the contributions to the expectation values due to a single boundary and to present the second plate-induced parts in terms of exponentially convergent integrals. Various limiting cases are investigated. The vacuum forces acting on the boundaries are presented as a sum of the self-action and 'interaction' terms. The first one contains well known surface divergences and needs a further renormalization. The 'interaction' forces between the plates are investigated as functions of the proper accelerations and coefficients in the boundary conditions. We show that there is a region in the space of these parameters in which the 'interaction' forces are repulsive for small distances and attractive for large distances.Comment: 20 pages, 2 figures, discussion added, accepted for publication in Int.

Motivational and estimation criterion of willingness of people to provide the civilian oversight at the local level

The main trend of the elite public policy since the second half of the 80-ies of the last century is the democratization of public life and development of civil society in Russia. Its implementation is associated with the design and introduction of a set of mechanisms that determine the relationship between the individual and social institutions of various levels and functional purpose. One such mechanism is civilian oversight over authorities. Ideologues of democracy believe that it allows to improve the efficiency of the power structures and minimize their deviation. The changes that are currently taking place in Russia make a significant adjustment to the behavior patterns characteristic of Russian citizens. In connection with the new understanding of the role of the citizen, the development of institutions of governmental authority and local self-government, there is a real need to find some new approaches to defining the essence of the concept of civilian oversigh

Specifics of anticoagulation in combination with atrial fibrillation and chronic kidney disease

Due to the population aging and the accumulation of concomitant diseases, the prevalence of atrial fibrillation (AF) as the most common arrhythmia is increasing. On the other hand, 14% of the population has chronic kidney disease (CKD). These conditions are often combined with each other causing a prothrombogenic effect, which significantly increase the number of unfavorable outcomes such as thromboembolism, stroke, myocardial infarction and cardiovascular death. This is especially true for the last stages of CKD, the so-called end-stage renal disease with a glomerular filtration rate <29 ml/min/1,73 m2. Previously, the vitamin K antagonist warfarin was the central drug for anticoagulant therapy of AF + CKD combination, but in the last decade, direct oral anticoagulants became widely used. This article discusses the evidence base for using each of the anticoagulants in patients with AF+CKD combination compared with warfarin, including depending on the severity of glomerular filtration rate decrease

Sociocultural aspect of realization of civil control in modern Russian society

The backwardness of civil control in modern Russia is connected with a complex of the reasons of sociocultural character, including with specifics of the Russian traditions of public participation. It is proved that only collective forms of civil control relying on mobilization and use of the social capital of local communities can be the most effective in Russi
