Decentralized Token Economy Theory (DeTEcT)
This paper presents a pioneering approach for simulation of economic
activity, policy implementation, and pricing of goods in token economies. The
paper proposes a formal analysis framework for wealth distribution analysis and
simulation of interactions between economic participants in an economy. Using
this framework, we define a mechanism for identifying prices that achieve the
desired wealth distribution according to some metric, and stability of economic
dynamics. The motivation to study tokenomics theory is the increasing use of
tokenization, specifically in financial infrastructures, where designing token
economies is in the forefront. Tokenomics theory establishes a quantitative
framework for wealth distribution amongst economic participants and implements
the algorithmic regulatory controls mechanism that reacts to changes in
economic conditions.\par In our framework, we introduce a concept of tokenomic
taxonomy where agents in the economy are categorized into agent types and
interactions between them. This novel approach is motivated by having a
generalized model of the macroeconomy with controls being implemented through
interactions and policies. The existence of such controls allows us to measure
and readjust the wealth dynamics in the economy to suit the desired objectives.Comment: 24 pages, 5 figures, 8 table
Based on Perceptron Object Classification Algorithms for Processing of Agricultural Field Images
Neural network algorithms of object classification are considered in the paper applying to disease area recognition of agricultural field images. The images are presented as reduced normalized histograms. The classification is carried out for RGB-and HSV-space by using of a multilayer perceptron
Sodium-23 Magnetic Resonance Imaging
23Na MRI provides additional biochemical information to 1H MRI in terms of cell integrity and tissue viability. We aimed at determining the sensitivity of 23Na MRS, MRI and MR relaxometry methods available on 7T MR scanner Bruker Biospec 70/30 USR and developing of an optimal MRI protocol for small animal 23Na in vivo visualization. The outcomes include 23Na MR spectra, 23Na MR images with SNRs, and T1 and T2 values of 23Na. It is shown that single-pulse 23Na MR spectroscopy can discriminate different 23Na concentrations, and 3D FLASH pulse sequence adapted for 23Na data acquisition may provide the acceptable quality images.

СРАВНЕНИЕ МЕТОДОВ СТЕГАНОГРАФИИ В ИЗОБРАЖЕНИЯХ
Steganography is a method of hiding information in other information of different format (container). There are many steganography techniques with various types of container. In the Internet, digital images are the most popular and frequently used containers. We consider main image steganography techniques and their advantages and disadvantages. We also identify the requirements of a good steganography algorithm and compare various such algorithms.Стеганография – это метод сокрытия информации в объектах различных форматов (кон-тейнерах). Существует большое разнообразие методов для конкретных контейнеров, в которые скрытно записывается информация. Наиболее часто в качестве контейнера используются цифровые изображения, которые без искажений могут пересылаться по компьютерным сетям. Исследуется основная методика стеганографии, ее сильные и слабые стороны. Дается сравнительная оценка основных алгоритмов стеганографии
