The analysis of morphometric features in two pairs of closed species of wool mice (Sylvaemus tauricus and S.sylvaticus) and voles (Terricola f1400ea-sb34 subterraneus and Microtus arvalis) is carried out.It is shown that the problems of diagnostics of morphologically closed species appear due to the coincidence of signs of the young stages of size-
In this paper, an improved LT code with a reverse coding framework is designed to reduce the error floor caused by low-degree information nodes.For the proposed coding scheme, a well-designed threshold is used to mark the information nodes whose degrees are less than the threshold, and these nodes will be coded reversely to connect to enough candid
In this article, we study the planar cubic differential systems with invariant affine straight lines of total parallel multiplicity seven.We classify these system according to their geometric properties encoded in the configurations of caravan scissor jack invariant straight lines.We show that there are only 17 different what does pre 98 mean topol
Canoe polo is an increasingly popular discipline requiring both kayaking and ball-handling skills.While the kinematics of the upper body during throw has been investigated for several overhead sports, the canoe polo throw has still to be studied.Therefore, the aim of this study is to analyze the canoe polo throw kinematics in terms of angles and in
