Glycosylation is a common modification reaction in plants. The products obtained upon glycosylation have different biological functions, making an important mechanism affecting and regulating the balance of plant growth metabolism. In this study, we first speculated that Group I apple glycosyltransferase family may predicted function like UGT83A1, according to gene chip data published online. S...

This report defines the rank complement of a diagonalizable matrix (i.e. a matrix which can be brought to a diagonal form by means of a change of basis) as the interchange of the range and the null space. Given a diagonalizable matrix A there is in general no unique matrix Ac which has a range equal to the null space of A and a null space equal to the range of A, only matrices of full rank have...

ing this paper new factorization techniques for computation of the Operational Space Mass Matrix (A) and its inverse (A-l) are developed. Starting with a new factorization of the inverse of mass matrix (M-l) in the form of Schur Complement as M-l = G’ %)TsI-lB, where d and 8 are block tridlagonal matrices and G is a tridiagonal matrix, similar factorization for A and A-i are derived. Specifical...

Given a 3-manifold M , there are generically infinitely many manifold which covers M . However, if we are restricted to the category of knot complements, the situation is quite different. It can be shown (see Lemma 1 and bellow) that if the complement E(K) of a knot K is n-fold covered by some knot complement, then the covering is cyclic, and K admits a cyclic surgery, i.e. a Dehn surgery such ...

Certain monoclonal antibodies (MoAbs) specific for platelet membrane glycoproteins are known t o be capable of activating platelets, and it is generally thought that platelets from normal subjects are equally susceptible t o stimulation by such MoAbs. We found that platelets from 20 normal donors varied significantly in their sensitivity to three lgGl murine MoAbs specific for membrane glycopro...
