Propagation dynamics for a competitive-cooperative recursion system with monostable structure

open access: yesMathematics Open
In this study, monostable traveling wave solutions were considered for a competitive-cooperative recursive system. We demonstrate the existence of monostable traveling wave solutions for these systems under suitable conditions by employing the theory of ...

Global bifurcation for the Whitham equation

open access: yes, 2013
We prove the existence of a global bifurcation branch of $2\pi$-periodic, smooth, traveling-wave solutions of the Whitham equation. It is shown that any subset of solutions in the global branch contains a sequence which converges uniformly to some ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes

open access: yesAdvanced Functional Materials, EarlyView.
The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Light‐Actuated Fiber‐Climbing Inchworm Robot Toward Endoluminal Navigation

open access: yesAdvanced Functional Materials, EarlyView.
A kirigami‐inspired soft inchworm robot harnesses optical energy from a customized side‐emitting optical fiber, guaranteeing its propulsion along the fiber body. The wavelength‐selective responsiveness of dye‐functionalized liquid crystal elastomers and the application of temporal illumination patterns enable sequential control of robot components. The

Stability of Periodic, Traveling-Wave Solutions to the Capillary-Whitham Equation

open access: yes, 2019
Recently, the Whitham and capillary-Whitham equations were shown to accurately model the evolution of surface waves on shallow water. In order to gain a deeper understanding of these equations, we compute periodic, traveling-wave solutions to both and ...
