glutathione s-transferases (gsts; ec: 2.5.1.18) are a ubiquitous family of eukaryotic and prokaryotic phase ii metabolic isozymes. genes encoding gstm1 (omim: 138350), and gstt1 (omim: 600436) are members of class mu and theta, respectively. the most common polymorphism in the gstm1 is a deletion of the whole gstm1 gene with a lack of enzyme activity. a homozygous deletion in the gstt1 has also...

The main focus of the paper is on the asymptotic behaviour of linear discrete-time positive systems. Emphasis is on highlighting the relationship between asymptotic stability and the structure of the system, and to expose the relationship between null-controllability and asymptotic stability. Results are presented for both time-invariant and time-variant systems.

In this paper, we give a novel abstract description of Szabo’s polycategories. We use the theory of double clubs – a generalisation of Kelly’s theory of clubs to ‘pseudo’ (or ‘weak’) double categories – to construct a pseudo-distributive law of the free symmetric strict monoidal category pseudocomonad onMod over itself qua pseudomonad, and show that monads in the ‘two-sided Kleisli bicategory’ ...

The Laplacian matrix is of fundamental importance in the study graphs, networks, random walks on lattices, and arithmetic curves. In certain cases, trace its pseudoinverse appears as only non-trivial term computing some intrinsic graph invariants. Here we a double sum Fn which associated with pseudo inverse for graphs. We investigate asymptotic behavior this n → ∞. Our approach based classical ...
