As a crucial component of the male reproductive system, the epididymis plays multiple roles, including sperm storage and secretion of nutritive fluids for sperm development and maturation. The acquisition of fertilization capacity by sperm occurs dur

Sperm gain fertilization ability and forward movement characteristics during epididymal transport. Sperm maturation is inseparable from the processing of the epididymis. Compared with other reproductive organs, relatively little is known about the ep

It is known that for each k ≥ 4 , there exists an irreducible sign pattern with minimum rank k that does not allow diagonalizability. However, it is shown in this paper that every square sign pattern A with minimum rank 2 that has no zero line allo

Financial risk management has focused on banking, accounting, and finance, and applied all kinds types of models to avoid those specific forms of risk. Risk management may be dealt with using the model of multi-agent systems. In this paper, we consid

Characterization of sign patterns that allow diagonalizability has been a long-standing open problem. In this article, necessary and sufficient conditions for a sign pattern to allow diagonalizability are obtained, in terms of allowing related proper

It is shown that a 2 × 2 complex matrix A is diagonally equivalent to a matrix with two distinct eigenvalues iff A is not strictly triangular. It is established in this paper that every 3 × 3 nonsingular matrix is diagonally equivalent to a matrix

In this paper, we consider group consensus problem with switching topology by giving a kind of new protocol in which communication graph weights are all nonnegative. This is also consistent with classic protocols. The sufficient conditions which grou

In mammals, ontogenesis starts from a fusion of spermatozoon and oocyte, which are produced by reductive nuclear division of a diploid germ cell in a specialised but complex biological process known as meiosis. However, little is known about the mech
