© Published under licence by IOP Publishing Ltd. LaF3:Pr3+ crystal is proposed as a promising media for an infrared quantum counter in the mid-infrared spectrum range. In this paper it has been shown that this crystal can ...

This paper is devoted to verifying of the empirical Zipf and Hips laws in natural languages using Google Books Ngram corpus data. The connection between the Zipf and Heaps law which predicts the power dependence of the ...

In this paper the method for modelling of word usage frequency time series is proposed. An artificial feedforward neural network was used to predict word usage frequencies. The neural network was trained using the maximum ...

Calculated of the potential well for electrons of the dust-electron plasma depending on the temperature, size of the dust particles, the distance between them and the kind of material of which they consist. The shape of ...
