Rate-induced tipping and saddle-node bifurcation for quadratic differential equations with nonautonomous asymptotic dynamics [PDF]

open access: yes, 2020
An in-depth analysis of nonautonomous bifurcations of saddle-node type for scalar differential equations $x'=-x^2+q(t)\,x+p(t)$, where $q\colon\R\to\R$ and $p\colon\R\to\R$ are bounded and uniformly continuous, is fundamental to explain the absence ...

Assembly–Energetics–Control (AEC) Design Framework for Rotary DNA Nanomachines

open access: yesChemBioChem, Volume 27, Issue 8, April 2026.
Rotary DNA nanomachine is an emerging research interest using DNA as building blocks to fabricate nature‐mimicking mechanisms. Here, we suggest a three‐dimensional conceptual framework to categorize the existing designs and identify underexplored directions.

Multiple front and pulse solutions in spatially periodic systems

open access: yesJournal 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

open access: yes
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.

Averaging of equations of viscoelasticity with singularly oscillating external forces

open access: yes, 2016
Given $\rho\in[0,1]$, we consider for $\varepsilon\in(0,1]$ the nonautonomous viscoelastic equation with a singularly oscillating external force $$ \partial_{tt} u-\kappa(0)\Delta u - \int_0^\infty \kappa'(s)\Delta u(t-s) d s +f(u)=g_{0}(t)+\varepsilon ^{

Mimicking Life: Autonomous Oscillating Artificial Cilia Driven by Chemical Power

open access: yesAdvanced 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

open access: yesBioEssays, 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]

open access: yesTransactions 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 ...

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

open access: yesThe 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 ...

Calculation of a Dynamical Substitute for the Real Earth–Moon System Based on Hamiltonian Analysis

open access: yesThe Astrophysical Journal
The Earth–Moon libration points no longer exhibit the dynamical characteristics of “equilibrium points” due to perturbation effects when applying the ephemeris model. By decoupling the forced motions within the ephemeris model and computing the dynamical
