Breathers and rogue waves for semilinear curl-curl wave equations
, 2022 We consider localized solutions of variants of the semilinear curl-curl wave equation $s(x)\partial_t^2U+\nabla\times\nabla\times+q(x)U\pm V(x)|U|^{p−1}U = 0$ for $(x,t)\in\mathbb{R^3}\times\mathbb{R}$ and arbitrary $p > 1$. Depending on the coefficients $s,q,V$ we can prove the existence of three types of localized solutions: time-periodic ...

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells
Advanced Materials Technologies, EarlyView.Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.

The Evolution Mechanism of Akhmediev Breather Propagating over Variable Bottoms
, 2022 Freak wave is defined as a crest height (distance from mean sea level to crest) greater than 1.25 times significant wave height or a wave height (distance from wave trough to wave crest) greater than two times significant wave height. Freak wave which is

Light‑Driven Propulsion of Graphene Aerogels in Microgravity
Advanced Science, EarlyView.Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Synchronization‐Dissipation in the Cardiorespiratory System
Advanced Science, EarlyView.By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Breather solutions for semilinear wave equations
We prove existence of real-valued, time-periodic and spatially localized solutions (breathers) of semilinear wave equations $V(x)u_{tt} - u_{xx} = Γ(x) |u|^{p-1} u$ on $\mathbb{R}^2$ for all values of $p\in (1,\infty)$. Using tools from the calculus of variations our main result provides breathers as ground states of an indefinite functional under ...
