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.

A Food Web Model of the Serengeti: Stability, Dynamics and Indirect Effects
African Journal of Ecology, Volume 64, Issue 1, January 2026.ABSTRACT Effective conservation management of a complex ecosystem like the Serengeti can benefit from a systems‐wide approach to interactions between functional groups. This study presents a food web model of the Serengeti based on generalised Lotka–Volterra equations parameterised using data from the literature. The internal equilibrium point is shown

Alexandria Engineering Journal, 2013 A numerical method based on an NM-set of general, hybrid of block-pulse function and Taylor series (HBT), is proposed to approximate the solution of nonlinear Volterra–Fredholm integral equations. The properties of HBT are first presented.

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 ...

Detection of Eco‐Evolutionary Dynamics in Communities Using Joint Species Distribution Models
Ecology Letters, Volume 29, Issue 1, January 2026.Diverse communities in nature are structured by an array of complex processes, and it can be difficult to separate and measure their effects. To better understand species composition, it is crucial to consider trait evolution as an additional component driving species responses to the environment.

Stability Issues for Selected Stochastic Evolutionary Problems: A Review
Axioms, 2018 We review some recent contributions of the authors regarding the numerical approximation of stochastic problems, mostly based on stochastic differential equations modeling random damped oscillators and stochastic Volterra integral equations.

Ecology Letters, Volume 29, Issue 1, January 2026.Caculations of response diversity can be based on species fundamental responses in isolation or their realised responses in the community using metrics of response dissimilarity and response divergence. Combining model simulations and a meta‐analysis, we show here that community stability in the context of pulse disturbance is primarily determined by ...

Dynamically Consistent Analysis of Realized Covariations in Term Structure Models
Mathematical Finance, Volume 36, Issue 1, Page 203-236, January 2026.ABSTRACT In this article, we show how to analyze the covariation of bond prices nonparametrically and robustly, staying consistent with a general no‐arbitrage setting. This is, in particular, motivated by the problem of identifying the number of statistically relevant factors in the bond market under minimal conditions.
