Extracts from Problems of Air Law, a collection of works of the Section of air law of the Aviakhim Society of the USSR and Aviakhim RSFSR

The difficulties of developing a body of international law to govern air travel is discussed. A summary of literature and agreements is presented as well as a brief history. Air space over the poles and the legality of methods of claiming territory in the polar regions is discussed

Wave Functions and Energies of Magnetopolarons in Semiconductor Quantum Wells

The classification of magnetopolarons in semiconductor quantum wells (QW) is represented. Magnetopolarons appear due to the Johnson - Larsen effect. The wave functions of usual and combined magnetopolarons are obtained by the diodanalization of the Schrodinger equation.Comment: 7 pages, 2 figure

Transmission of a Symmetric Light Pulse through a Wide QW

The reflection, transmission and absorption of a symmetric electromagnetic pulse, which carrying frequency is close to the frequency of an interband transition in a QW (QW), are obtained. The energy levels of a QW are assumed discrete, one exited level is taken into account. The case of a wide QW is considered when a length of the pulse wave, appropriate to the carrying frequency, is comparable to the QW's width. In figures the time dependencies of the dimensionless reflection, absorption are transmission are represented. It is shown, that the spatial dispersion and a distinction in refraction indexes influence stronger reflection.Comment: 8 pages,8 figures with caption

Ways of Revealing Resistance Against Polygraph Testing

"Itis logical to assume that practically all examined persons involved in events under investigation in one form or another (skilfully or unskilfully) try to resist a polygraph. Considering the easy access to information on modern technologies of carrying out psychophysiological tests in screening (PPT) and ways of fighting against them, the problem of effective attempts at resist­ ance becomes rather relevant. "(...

Constitutional-Legal and Political Responsibility of Political Parties in the Russian Federation to Electors

Analysis of the legal and political responsibility of officials of a democratically elected state to their constituents. The subjects of the above responsibility may be elected officials of the legislative (representative) bodies of state power. The constitutional status of elected persons exercising public authority on behalf of individuals suggests the possibility of terminating their powers as sanctions only on the basis of the rules of law enshrined in the relevant acts and establishing clear reasons and procedures for liability. The current legislation of the Russian Federation provides for various types of constitutional and legal sanctions

Effect of the Spatial Dispersion on the Shape of a Light Pulse in a Quantum Well

Reflectance, transmittance and absorbance of a symmetric light pulse, the carrying frequency of which is close to the frequency of interband transitions in a quantum well, are calculated. Energy levels of the quantum well are assumed discrete, and two closely located excited levels are taken into account. A wide quantum well (the width of which is comparable to the length of the light wave, corresponding to the pulse carrying frequency) is considered, and the dependance of the interband matrix element of the momentum operator on the light wave vector is taken into account. Refractive indices of barriers and quantum well are assumed equal each other. The problem is solved for an arbitrary ratio of radiative and nonradiative lifetimes of electronic excitations. It is shown that the spatial dispersion essentially affects the shapes of reflected and transmitted pulses. The largest changes occur when the radiative broadening is close to the difference of frequencies of interband transitions taken into account.Comment: 7 pages, 5 figure

A CDCL-style calculus for solving non-linear constraints

In this paper we propose a novel approach for checking satisfiability of non-linear constraints over the reals, called ksmt. The procedure is based on conflict resolution in CDCL style calculus, using a composition of symbolical and numerical methods. To deal with the non-linear components in case of conflicts we use numerically constructed restricted linearisations. This approach covers a large number of computable non-linear real functions such as polynomials, rational or trigonometrical functions and beyond. A prototypical implementation has been evaluated on several non-linear SMT-LIB examples and the results have been compared with state-of-the-art SMT solvers.Comment: 17 pages, 3 figures; accepted at FroCoS 2019; software available at <http://informatik.uni-trier.de/~brausse/ksmt/

IDIOPATHIC NORMAL PRESSURE HYDROCEPHALUS (HAKIM-ADAMS SYNDROME): CLINICAL SYMPTOMS, DIAGNOSIS AND TREATMENT

Idiopathic normal pressure hydrocephalus is a chronic steadily progressing disease. Nowadays a vital and acute socially significant problem still has not been solved. The etiology and pathogenesis of this disease remain so far poorly understood. Variable clinical manifestations, as well as difficulties in differential diagnosis with other neurodegenerative diseases - lead to unde r- diagnosing of the illness that causes a significant decrease in patient’s quality of life and even results in disability. The n umber of patients with idiopathic normal pressure hydrocephalus has been steadily increasing. That is why, the coverage and a full study of this problem is of great interest for a broad circle of medical professionals
