Bohl Theorem for Volterra Equations
VNU Journal of Science: Mathematics - Physics, 2022 This work deals with the preservation of exponential stability under small perturbations for Volterra differential equations. The so-called Bohl-Perron type stability theorems for these systems are also studied.

SECURITY AND PRIVACY, Volume 9, Issue 1, January/February 2026.ABSTRACT Unarguably, malware and their variants have metamorphosed into objects of attack and cyber warfare. These issues have directed research focus to modeling infrastructural settings and infection scenarios, analyzing propagation mechanisms, and conducting studies that highlight optimized remedial measures.

Известия Иркутского государственного университета: Серия "Математика", 2016 The regularization method of linear integral Volterra equations of the first kind is considered. The method is based on the perturbation theory. In order to derive the estimates of approximate solutions and regularizing operator norms we use the Banach ...

Boundedness of solutions of matrix nonlinear volterra difference equations
Discrete Dynamics in Nature and Society, 2002 Nonlinear discrete-time Volterra equations in a Euclidean space are considered. Conditions for the boundedness of solutions are established by virtue of recent estimates for the norm of the resolvent of Volterra operators.

Boundedness of Discrete Volterra Equations
Journal of Mathematical Analysis and Applications, 1997 The boundedness and stability of the solutions of discrete Volterra equations are investigated. This is done by different techniques: the use of Lyapunov functionals, the methods of majorants (comparison theorem), and perturbation techniques. The results are then applied to the discretization by direct quadrature methods of Volterra integral equations ...

An Engineered Probiotic Consortium Based on Quorum‐Sensing for Colorectal Cancer Immunotherapy
Advanced Science, Volume 12, Issue 46, December 11, 2025.This work develops an engineered probiotic consortium sensing pH, hypoxia, and lactate in the tumor microenvironment. It releases a lactate‐depleting enzyme (LdhA) and a PD‐L1 nanobody. In humanized mouse models (MC38 and HT‐29 tumors), it achieves durable oscillations, suppresses tumors, activates CD8+, CD4+, IFN‐γ+ T cells, and reduces Foxp3 ...

Integrable Origins of Higher Order Painleve Equations [PDF]
, 2010 Higher order Painleve equations invariant under extended affine Weyl groups $A^{(1)}_n$ are obtained through self-similarity limit of a class of pseudo-differential Lax hierarchies with symmetry inherited from the underlying generalized Volterra lattice ...
