A practical guide to characterising ecological coexistence

open access: yesBiological Reviews, Volume 101, Issue 1, Page 195-220, February 2026.
ABSTRACT Coexistence is simultaneously one of the most fundamental concepts of ecology, and one of the most difficult to define. A particular challenge is that, despite a well‐developed body of research, several different schools of thought have developed over the past century, leading to multiple independent, and largely isolated, branches of ...

Data‐Driven Sliding Mode Control for Partially Unknown Nonlinear Systems

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 2, Page 629-638, 25 January 2026.
ABSTRACT This paper presents a novel data‐driven control framework for multi‐input multi‐output (MIMO) nonlinear systems with partially unknown dynamics and bounded disturbances. In practical scenarios, exact cancellation of system nonlinearities is often infeasible due to limited model information and unpredictable disturbances.

Frequency‐Domain Analysis of a Keldysh‐Like System

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 2, Page 671-682, 25 January 2026.
ABSTRACT Complex dynamics of the system, revealing flutter and first presented by M. Keldysh, is analyzed in the paper in the frequency domain, through the describing function method. Motivated by this analysis, a system with similar behavior, but suitable for the exact frequency‐domain analysis through the locus of a perturbed relay system (LPRS ...
