... Markov chains are used as a model for the sequence of elements of a natural language text. This model is applied for authorship attribution of texts. An element of a text could be a letter or a grammatical class of a word. It turns out that the frequencies of usage of letter pairs and pairs of grammatical classes are stable characteristics of the author, and they could be used in disputed authorship attribution. ... The research is carried out over 385 texts of 82 writers. ... 282/385 . ...

by Margarita Dzhalalova It is known that the pressure difference values for a round parachute are constant over total canopy, then for a square parachute the values of pressure difference are non-uniform along radial ribbons differing even from each other and depending mainly on certain sets of line lengths, and therefore square parachutes attain different shapes from each other ( Fig.1 - photo of var.1 and var.2). ... Distribution of pressure coefficient along radial ribbons of square parachute. ...

... Individual SELEX products, aptamers, are small molecules (40ґ100 nt) that have a unique three-dimensional structure, which provides for their specific and high-affinity binding to targets varying from low-molecular-weight ligands to proteins. ... Selection of aptamers binding with a target is the key step in SELEX, as aptamers account for only a small fraction of the initial library (one aptamer per 109 to 1013 molecules) [6]. ... Fourth, modification can increase the aptamer affinity for a target. ...

In this way he revealed a good correspondence between the concentric levels built by him in this relationship of the three Sri Yantra and the orbits of the planets of the solar system (Fig. 10, shows the first two out of three stars examined by him) with a divergence from the real diameters of orbits of about 1.5%. ...
