Study Some Properties of a Circulant Matrix

Tikrit Journal of Pure Science, 2023
The aim of this paper is to study the properties of idempotent, nilpotent and stability to a circulant matrix  which generated by the first row, finally we showed the relation between this properties with eigenvalues of this matrix.

The structure of EXTL3 helps to explain the different roles of bi-domain exostosins in heparan sulfate synthesis

Nature Communications, 2022
Heparan sulphate (HS)—a common cell surface decoration—is a carbohydrate of alternating sugars assembled by bi-domain enzymes such as EXTL3. Here, authors present the structure of EXTL3, explain EXTL3 lost activity, and propose that HS extension is ...

Hysteresis and Stability

SIAM Review, 2023
Hysteresis can be defined from a dynamical systems perspective with respect to equilibrium points. Consequently, hysteresis naturally lends itself as a topic to illustrate and extend concepts in a dynamical systems course. A number of examples exhibiting hysteresis, most motivated by applications, are presented.

Removal of glucuronic acid from xylan is a strategy to improve the conversion of plant biomass to sugars for bioenergy

Biotechnology for Biofuels, 2017
Background Plant lignocellulosic biomass can be a source of fermentable sugars for the production of second generation biofuels and biochemicals. The recalcitrance of this plant material is one of the major obstacles in its conversion into sugars ...
