Nonlinear axion electrodynamics: Axionically induced electric flares in the early magnetized universe
Alexander B. Balakin, Vladimir V. Bochkarev, Albina F. Nizamieva
We consider the nonlinearly extended Einstein-Maxwell-axion theory, which is based on the account for two symmetries: first, the discrete symmetry associated with the properties of…
Comparative analysis of criteria for filtering time series of word usage frequencies
Inna A. Belashova, Vladimir V. Bochkarev
This paper describes a method of nonlinear wavelet thresholding of time series. The Ramachandran-Ranganathan runs test is used to assess the quality of approximation. To minimize t…
Dynamics of core of language vocabulary
Valery D. Solovyev, Vladimir V. Bochkarev, Anna V. Shevlyakova
Studies of the overall structure of vocabulary and its dynamics became possible due to creation of diachronic text corpora, especially Google Books Ngram. This article discusses th…
Verifying Heaps' law using Google Books Ngram data
Vladimir V. Bochkarev, Eduard Yu. Lerner, Anna V. Shevlyakova
This article is devoted to the verification of the empirical Heaps law in European languages using Google Books Ngram corpus data. The connection between word distribution frequenc…
The exact power law and Pascal pyramid
Vladimir V. Bochkarev, Eduard Yu. Lerner
Let be a full set of outcomes (letters, symbols) and let positive , , be their probabilities (). Let us treat as…
Initialization of multilayer forecasting artifical neural networks
Vladimir V. Bochkarev, Yulia S. Maslennikova
In this paper, a new method was developed for initialising artificial neural networks predicting dynamics of time series. Initial weighting coefficients were determined for neurons…
