Decomposition method and its application to the extremal problems
Archives of Control Sciences, 2016 In the article solution of the problem of extremal value of x(τ) is presented, for the n-th order linear systems. The extremum of x(τ) is considered as a function of the roots s1, s2, ... sn of the characteristic equation.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Paradigmatic well posedness in some generalized characteristic Cauchy problems [PDF]
By means of convenient regularization for an ill posed Cauchy problem, we deï¬ne an associated generalized problem and discuss the conditions for the solvability of it.

Electronic Journal of Differential Equations, 2010 We study some properties concerning the asymptotic behavior of solutions to nonautonomous retarded functional differential equations, depending on the knowledge of certain solutions of the associated generalized characteristic equation.

On matrices whose characteristic equations are identical [PDF]
Proceedings of the American Mathematical Society, 1950 In a previous paper [1 ]I it was shown that if A and C are matrices such that A CA = 0 and B is an arbitrary matrix, then AB and A (B + C) have the same characteristic equation. It is the purpose of this note to prove two theorems, each of which gives the above result as a special case. THEOREM 1.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Stability Switches of A Neural Field Model: An Algebraic Study On The Parameters
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020 In thispaper, a special case for a delayed neural field model is considered. Afterconstructing its characteristic equation a stability analysis is made. UsingRouth-Hurwitz criterion, some conditions for characteristic equation are givenfor the stability ...

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
