On the $Psi$-stability of a nonlinear Volterra integro-differential system
Electronic Journal of Differential Equations, 2005 In this paper we prove sufficient conditions for $Psi$-stability of the zero solution of a nonlinear Volterra integro-differential system.

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Asymptotic stability of switching systems
Electronic Journal of Differential Equations, 2010 In this article, we study the uniform asymptotic stability of the switched system $u'=f_{ u(t)}(u)$, $uin mathbb{R}^n$, where $ u:mathbb{R}_{+}o {1,2,dots,m}$ is an arbitrary piecewise constant function. We find criteria for the asymptotic stability

On the uniform exponential stability of linear time-delay systems
International Journal of Mathematics and Mathematical Sciences, 2004 This paper deals with the global uniform exponential stability independent of delay of time-delay linear and time-invariant systems subject to point and distributed delays for the initial conditions being continuous real functions except possibly on a ...

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

An Asymptotic Stability and a Uniform Asymptotic Stability for Functional Differential Equations [PDF]
Proceedings of the American Mathematical Society, 1993 We consider a system of functional differential equation x ′ ( t ) = F ( t , x t ) {x’}(t) = F(t,{x_t}) and obtain conditions on a Liapunov functional to ensure the ...

YIPFα1A expression is regulated by multilayered molecular mechanisms
FEBS Open Bio, EarlyView.YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Uniform stability of displacement coupled second-order equations
Electronic Journal of Differential Equations, 2001 We prove that the uniform stability of semigroups associated to displacement coupled dissipator systems is equivalent to the uniform stability of velocity coupled dissipator systems.

Representation Theorem for Stochastic Differential Equations in Hilbert Spaces and its Applications [PDF]
Surveys in Mathematics and its Applications, 2006 In this survey we recall the results obtained in [Ungureanu,Electronic Journal of Qualitative Theory of Differential Equations, 2004] where we gave a representation theorem for the solutions of stochastic differential equations in Hilbert spaces.

On the uniform asymptotic stability in functional-differential equations [PDF]
Proceedings of the American Mathematical Society, 1982 We consider a system of functional differential equations x ′ ( t ) = F ( t , x t ) x’(t) = F(t,{x_t}) and obtain conditions on a Liapunov functional to insure the uniform asymptotic stability ...
