Evaluation of error probability in determining of reception time of RZS in the presence of white noise
The error origins in determining of reception time of radio probing signal are considered in this article. Also the method of error probability calculation was offered in this work. The analysis of maximum probability of such error was carried out for phase-shift keyed signal on the base of Barker’s code and radio signal without intrapulse modulation.

Condorcet interpretation of probability’s theory: the use of a mathematical construct to the field of social action
Probability theory, which emerged as early as the 17th century thanks to the works of Pascal and Fermat, served for a long time as a tool of professional mathematicians. It was not considered a means of rational prediction of social actions. In the late 18th century, Nicolas de Condorcet (1743—1794) first proposed to apply probability theory to moral and political disciplines thus creating a basis for social forecasting. The methods he developed made it possible to predict the results of political...

The central philosophical conception of the creator of logical algebra: On the bicentenary of George Boole
The article considers the history of George Boole’s main philosophical conception consisting in using his logical-algebraic and theoretical-probabilistic methods in modelling thought processes. Despite the project’s failure, current developments in computer science and programming have surprisingly confirmed Boole’s ideas on the applicability of rigorous methods of logical calculus in the explication of thought processes.

These processes were most pronounced in the first years of the 21st century. Probably, they mark the beginning of Finland’s transition to a ‘new society’ that is not based on Christian values. Similar processes are observed in other countries of United Europe. The authors establish a connection between secularisation processes ...

Evolution operator of a combined system consisting of the measured qubit and the auxiliary system is derived. Conditions on the choice of parameters in the formula for the reconstruction of the measured qubit states are obtained. The evolution operator of the combined system leads to the probability operator (or effect) with a structure that corresponds to unsharp measurements.

The greater seasonal rise in water temperatures in 1990-2000, presumably, a consequence of the climate change, alongside with other factors (freshness, slow water flow) creates conditions for cyanobacterial «hyperblooms». Probably, the 1990-2000 climate warming is the cause of the eutrophication of the Curonian Lagoon, which continues despite significant reduction in external nutrient load.

Lessing’s “code of hope”, whose ideas developed in the “pre-critical” period of the Elightenment is based on trust in human sensibility, within which, probably unconsciously, in the conditions of newly established autonomy, he discovers the heteronomous orientation of the “compassion” and “fear” existentials underlying his theory of catharsis. In Lessing’s system, these “vertically” positioned ...

I consider the correlation between the mechanisms of text coherence, on the one hand, and the relationships of transworld accessibility and of the identification of described individuals across possible worlds, on the other. Probably, the variety of cohesion mechanisms does not make it possible to use a single identification mechanism and requires taking into account various competing approaches. I illustrate the above conclusions, using Pushkin’s draft ‘If I were Tsar…’

Abandoned after the Revolution, the honorific underwent a revival in the second half of the 20th century when it was used more often to address a mixed company than it had been in tsarist times. Probably, this was accounted for by extra-linguistic factors. Special attention is given to the use of the honorific gospoda in periods of transition: at the beginning and end of the Soviet era and after the collapse of the USSR.

The forecast is based on the scenario methodology, which suggests that the modern means of political forecasting make it possible to make conclusions not...
Portfolio optimization in the case of an exponential utility function and in the presence of an illiquid asset
We study an optimization problem for a portfolio with a risk-free, a liquid, and an illiquid risky asset. The illiquid risky asset is sold in an exogenous random moment with a prescribed liquidation time distribution. We assume that the investor chooses an exponential utility function. Study of optimization problems with three assets including an illiquid asset leads to three-dimensional nonlinear Hamilton — Jacobi — Bellman (HJB) equations.
It is well known that the exponential utility function...
Socially efficient entry barriers?
Stagnation of the Russian economy lends a new urgency to the question of whether reserves of competition incentives can be used to overcome the current negative economic tendencies. The lowering of entry barriers is traditionally considered a universal instrument of promoting competition. However, lower entry barriers can be mistakenly associated with bringing the market closer to the state of the so-called ‘perfect’ competition. The authors aim to show that the absence of entry barriers does not...
