Computation of semi-analytical solutions of fuzzy nonlinear integral equations

open access: yesAdvances in Difference Equations, 2020
In this article, we use a fuzzy number in its parametric form to solve a fuzzy nonlinear integral equation of the second kind in the crisp case. The main theme of this article is to find a semi-analytical solution of fuzzy nonlinear integral equations. A

A Survey of SIR‐Based Differential Epidemic Models for Control and Security Against Malware Propagation in Computer Networks

open access: yesSECURITY 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.

Exponential asymptotic stability for linear volterra equations [PDF]

open access: yes, 2000
This note studies the exponential asymptotic stability of the zero solution of the linear Volterra equation x˙ (t) = Ax(t) + t 0 K(t − s)x(s) ds by extending results in the paper of Murakami “Exponential Asymptotic Stability for scalar linear ...

An Engineered Probiotic Consortium Based on Quorum‐Sensing for Colorectal Cancer Immunotherapy

open access: yesAdvanced 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 ...

On Monotonic and Nonnegative Solutions of a Nonlinear Volterra-Stieltjes Integral Equation

open access: yesJournal of Function Spaces, 2014
We study the existence of monotonic and nonnegative solutions of a nonlinear quadratic Volterra-Stieltjes integral equation in the space of real functions being continuous on a bounded interval. The main tools used in our considerations are the technique

Ventilatory Complexity Persists in Phox2b Mutant Mice Lacking the Retrotrapezoid Nucleus/Parafacial Respiratory Group (RTN/pFRG) and in Humans With Congenital Central Hypoventilation Syndrome

open access: yesJournal of Comparative Neurology, Volume 533, Issue 12, December 2025.
Phox2B mutant mice and patients with congenital central hypoventilation syndrome exhibit ventilatory variability and complexity comparable to those of controls, suggesting that the RTN/pFRG nucleus is not required for brainstem central pattern generators to generate complex breathing.

An approximate solution of two dimensional nonlinear Volterra integral equation using Newton-Kantorovich method [PDF]

open access: yes, 2016
This paper studies the method for establishing an approximate solution of nonlinear two dimensional Volterra integral equations (NLTD-VIE). The Newton-Kantorovich (NK) suppositions are employed to modify NLTD-VIE to the sequence of linear two dimensional

Interaction strength and harvest intensity mediate predator–prey dynamics on coral reefs

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Understanding predator–prey relationships is fundamental to our knowledge of the stability and resilience of ecological systems. These dynamics are shaped by both ecological factors, like interaction strength, and anthropogenic factors, like harvest intensity, which can have large‐scale implications for community structure.
