Multiple front and pulse solutions in spatially periodic systems
Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.Abstract In this paper, we develop a comprehensive mathematical toolbox for the construction and spectral stability analysis of stationary multiple front and pulse solutions to general semilinear evolution problems on the real line with spatially periodic coefficients.

Monotone Nonautonomous Dynamical Systems
The monograph present ideas and methods, developed by the author, to solve the problem of existence of Bohr/Levitan almost periodic respectively, almost recurrent in the sense of Bebutov, almost authomorphic, Poisson stable solutions and global attractors of monotone nonautonomous differential/difference equations.

Mimicking Life: Autonomous Oscillating Artificial Cilia Driven by Chemical Power
Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.The synthesis and motion analysis of chemically actuated, individually autonomous artificial cilia are presented. Driven by an internal chemical reaction, the self‐driven individual cilia require no external stimuli. They undergo periodic oscillatory motion with a 3D beat pattern and exhibit chemotactic shifts, reminiscent of biological systems.

Transposon Ecology and the Octopus Genome
BioEssays, Volume 48, Issue 3, March 2026.Transposable elements (TEs) are mobile strands of DNA prevalent in octopus genomes. TE activity in the octopus brain might reflect an organism‐beneficial role in cognition; or could be a deleterious byproduct of TE parasitism. Viewing TEs from a genome‐ecology perspective generates novel predictions about differential expression levels across “genomic ...

Morse decompositions of nonautonomous dynamical systems [PDF]
Transactions of the American Mathematical Society, 2007 The global asymptotic behavior of dynamical systems on compact metric spaces can be described via Morse decompositions. Their components, the so-called Morse sets, are obtained as intersections of attractors and repellers of the system. In this paper, new notions of attractor and repeller for nonautonomous dynamical systems are introduced which are ...

The Plant Genome, Volume 19, Issue 1, March 2026.Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...

Faedo-Galerkin approximation of mild solutions of fractional functional differential equations
Nonautonomous Dynamical Systems, 2021 In the paper, we discuss the existence and uniqueness of mild solutions of a class of fractional functional differential equations in Hilbert space separable using the Banach fixed point theorem technique.

Continuous data assimilation for the Richards equation of unsaturated flow: A computational study
Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.Abstract Azouani–Olson–Titi data assimilation (often referred to as AOT, after its authors) is a computationally‐efficient algorithm that has been shown analytically and computationally to recover the true solution for a wide variety of regimes exponentially fast in time, in addition to being robust with respect to noisy data, stochastic forcing, and ...
