Computational Methods in Systems Biology admits a symplectic structure iff . = ker(.) for some von Neumann regular alternating matrix . ∈ M.(.). Every .-generated symplectic space over . arises in this way. In supplement to this, it is also shown that a matrix . ∈ M.(.) is von Neumann regular iff each of its determinantal ideals is genera

Timing and Pacing of Team Communication,Cohen-Macaulay type, type sequences and almost Gorenstein rings etc. In Section 2 we give summary of numerical invariants of monomial curves, especially monomial curves defined by arithmetic sequences and almost arithmetic sequences. In particular, we give an explicit formula for the type sequence (
