A note on the existence of non-monotone non-oscillating wavefronts

, 2013
In this note, we present a monostable delayed reaction-diffusion equation with the unimodal birth function which admits only non-monotone wavefronts.

Asymptotic convergence to pushed wavefronts in a monostable equation with delayed reaction

, 2014
We study the asymptotic behaviour of solutions to the delayed monostable equation $(*)$: $u_{t}(t,x) = u_{xx}(t,x) - u(t,x) + g(u(t-h,x)),$ $x \in R,\ t >0,$ with monotone reaction term $g: R_+ \to R_+$.

Spreading speeds and traveling waves for nonlocal dispersal equations with degenerate monostable nonlinearity

Journal of Differential Equations, 2012
The authors investigate the spreading speeds and traveling wave solutions of a nonlocal dispersal equation with degenerate monostable nonlinearity by using the Laplace transform and the maximum principle in complex analysis based on the paper of \textit{J. Coville} and \textit{L. Dupaigne} in [Proc. R. Soc. Edinb., Sect. A, Math. 137, No.

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

Advanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

Advanced Intelligent Systems, EarlyView.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Existence of Bistable Waves in a Competitive Recursion System with Ricker Nonlinearity [PDF]

, 2013
Using an abstract scheme of monotone semiflows, the existence of bistable traveling wave solutions of a competitive recursion system with Ricker nonlinearity is established. The traveling wave solutions formulate the strong inter-specific actions between

Asymptotic behavior of solutions of a reaction diffusion equation with free boundary conditions

, 2014
We study a nonlinear diffusion equation of the form $u_t=u_{xx}+f(u)\ (x\in [g(t),h(t)])$ with free boundary conditions $g'(t)=-u_x(t,g(t))+\alpha$ and $h'(t)=-u_x(t,g(t))-\alpha$ for some $\alpha>0$.

Remorphable Architectures: Reprogramming Global Bistability through Locally Bistable Metamaterials

Advanced Materials, Volume 38, Issue 9, 12 February 2026.
Local bistable reconfiguration in mechanical metamaterials is leveraged in globally bistable architectures to enable in situ reprogrammable transition pathways through state flip of individual building blocks. The local‐to‐global correspondence of instabilities empowers soft robotic systems with on‐demand morphing traits, as well as aerospace ...

Entire solutions of nonlocal dispersal equations with monostable nonlinearity in space periodic habitats

Journal of Differential Equations, 2016
The paper under review deals with new types of entire solutions, other than traveling wave solutions, of nonlocal dispersal equations with monostable nonlinearity in space periodic habitats of the type \[ u_t(x,t)=\int_{\mathbb R^N} J(y-x)u(y,t)\;dy - u(x,t)+u(x,t)f(x,u(x,t)),\quad x\in\mathbb R^N, \] where \(u(x, t)\) denotes the population density of

Entangled Multistable Origami with Reprogrammable Stiffness Amplification and Damping

Advanced Functional Materials, Volume 36, Issue 5, 15 January 2026.
This study introduces a class of origami‐inspired metamaterials that overcome the limitations of existing multistable metamaterials by eliminating the need for rigid lateral confinements. Panel entanglement, snap‐through interactions, and instabilities synergy enable them to achieve extensive shape‐shifting, enhanced stiffness, and remarkable energy ...
