On the Distribution of the spt-Crank
Mathematics, 2013 Andrews, Garvan and Liang introduced the spt-crank for vector partitions. We conjecture that for any n the sequence {NS (m, n)}m is unimodal, where NS (m, n) is the number of S-partitions of size n with crank m weight by the spt-crank.

Investigation of the kinematics of mechatronic device drive based on a spatial mechanism [PDF]
Омский научный вестник, 2022 In this paper, we consider the scheme of mechatronic device based on a spatial mechanism. The scheme is designed in such a way that the working elements are combined with the elements of the transmission mechanism — links.
