Herpes murine model as a biological assay to test dialyzable leukocyte extracts activity. [PDF]
J Immunol Res, 2015 Human dialyzable leukocyte extracts (DLEs) are heterogeneous mixtures of low‐molecular‐weight peptides that are released on disruption of peripheral blood leukocytes from healthy donors. DLEs improve clinical responses in infections, allergies, cancer, and immunodeficiencies.

On the Jordan decomposition of tensored matrices of Jordan canonical forms [PDF]
, 2008 Let k be an algebraically closed field of characteristic p \ge 0. We shall consider the problem of finding out a Jordan canonical form of J(\alpha,s) \otimes_{k} J(\beta,t), where J(\alpha,s) means the Jordan block with eigenvalue \alpha \in k and size s.

The strong nil-cleanness of semigroup rings
Open Mathematics, 2020 In this paper, we study the strong nil-cleanness of certain classes of semigroup rings. For a completely 0-simple semigroup M=ℳ0(G;I,Λ;P)M={ {\mathcal M} }^{0}(G;I,\text{Λ};P), we show that the contracted semigroup ring R0[M]{R}_{0}{[}M] is ...

Hilbert series and applications to graded rings
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 7, Page 397-403, 2003., 2003 This paper contains a number of practical remarks on Hilbert series that we expect to be useful in various contexts. We use the fractional Riemann‐Roch formula of Fletcher and Reid to write out explicit formulas for the Hilbert series P(t) in a number of cases of interest for singular surfaces (see Lemma 2.1) and 3‐folds. If X is a ℚ‐Fano 3‐fold and S ∈

Distractions of Shakin rings [PDF]
, 2013 We study, by means of embeddings of Hilbert functions, a class of rings which we call Shakin rings, i.e. quotients K[X_1,...,X_n]/a of a polynomial ring over a field K by ideals a=L+P which are the sum of a piecewise lex-segment ideal L, as defined by ...

Some properties of graded comultiplication modules
Open Mathematics, 2017 Let G be a group with identity e. Let R be a G-graded commutative ring and M a graded R-module. In this paper we will obtain some results concerning the graded comultiplication modules over a commutative graded ring.

The Noether number of the non-abelian group of order 3p [PDF]
, 2012 It is proven that for any representation over a field of characteristic 0 of the non-abelian semidirect product of a cyclic group of prime order p and the group of order 3 the corresponding algebra of polynomial invariants is generated by elements of ...

Lefschetz Properties for Higher Order Nagata Idealizations [PDF]
, 2019 We study a generalization of Nagata idealization for level algebras. These algebras are standard graded Artinian algebras whose Macaulay dual generator is given explicity as a bigraded polynomial of bidegree $(1,d)$. We consider the algebra associated to
