Time-relevant 2D behaviors [PDF]

open access: yes, 2011
In this work we present some results on 2D behaviors described by linear constant coefficient partial difference equations where one of the independent variables, “time”, is distinguished and plays a special role. We call such systems ‘time-relevant’. We

On Stable Instances of MINCUT

open access: yesМоделирование и анализ информационных систем, 2014
A combinatorial optimization problem is called stable if its solution is preserved under perturbation of the input parameters that do not exceed a certain threshold – the stability radius.

On the Stability of Some Exponential Polynomials

open access: yesJournal of Mathematical Analysis and Applications, 1997
The authors deal with the transcendental equation of the type \[ (z+ pz+ q)\exp(\tau z)+ rz=0, \] where \(p\), \(q\), \(r\), \(\mathbb{R}\), \(\tau, p>0\), \(q>0\), \(r=0\), \(n=0,1,2\). The main results are concerned with the case \(n=0\), which is important in the stability theory of delay.

Certificates for Properties of Stability Polynomials of Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2014
A stable (or independent) set is a set of vertices where no two of the vertices in the set are adjacent. The stability polynomial $A(G; p)$ of a graph $G$ is the probability that a set of randomly chosen vertices is stable where the probability of each vertex being chosen is $p$, with choices independent.

On a logarithmic criterion for uniform polynomial stability

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2018
The paper presents a logarithmic criterion for uniform polynomial stability of evolution operators in Banach spaces. As applications, another four characterizations of uniform polynomial stability are obtained.

FEEDBACK STABILIZATION OF HOMOGENEOUS POLYNOMIAL SYSTEMS [PDF]

open access: yesIFAC Proceedings Volumes, 1995
The propose of this paper is to drive a simple necessary and sufficient stabilizability condition for a class of multi-inputs polnomial systems. This result represents a generalization of the main theorems of (Iggidr and Vivalda, 1992). The stabilizing feedbacks are explicitly given.

Parametric Transient Stability Constrained Optimal Power Flow Solved by Polynomial Approximation Based on the Stochastic Collocation Method

open access: yesEnergies, 2022
To better respond to the impact of power system-uncertain parameters on transient stability, a novel model named the parametric transient stability constrained optimal power flow (parametric TSCOPF) is proposed.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

The root condition for polynomial of the second degree and a spectral analysis for three-level finite-difference schemes

open access: yesLietuvos Matematikos Rinkinys, 1998
This paper deals with a root condition for polynomial of the second degree. We propose the root condition criterion for such polynomial wiith complex coefficients. The criterion coincide with well-known Hurwitz criterion in the case of real coefficients.
