Nonquasilinear evolution of particle velocity in incoherent waves with random amplitudes
, 2008 The one-dimensional motion of $N$ particles in the field of many incoherent waves is revisited numerically. When the wave complex amplitudes are independent, with a gaussian distribution, the quasilinear approximation is found to always overestimate ...

On the principle of linearized stability for quasilinear evolution equations in time‐weighted spaces
Mathematische Nachrichten, Volume 298, Issue 12, Page 3939-3959, December 2025.Abstract Quasilinear (and semilinear) parabolic problems of the form v′=A(v)v+f(v)$v^{\prime }=A(v)v+f(v)$ with strict inclusion dom(f)⊊dom(A)$\mathrm{dom}(f)\subsetneq \mathrm{dom}(A)$ of the domains of the function v↦f(v)$v\mapsto f(v)$ and the quasilinear part v↦A(v)$v\mapsto A(v)$ are considered in the framework of time‐weighted function spaces ...

Nonlinear parallel momentum transport in strong turbulence
, 2015 Most existing theoretical studies of momentum transport focus on calculating the Reynolds stress based on quasilinear theory, without considering the \emph{nonlinear} momentum flux-$$.

Nanoimprinted Collagen Plasmonic Sensors
Small Structures, Volume 6, Issue 12, December 2025.A process to create collagen 3D nanostructures has been developed based on thermal nanoimprinting using mild conditions. This versatile process is suitable for transferring collagen patterns to both soft and rigid substrates, allowing for applications in various fields, including biomedicine and bio‐organic electronics.

Chorus Wave–Driven Electron Dynamics in the Van Allen Belts: From Coherence to Diffusion
AGU Advances, Volume 6, Issue 6, December 2025.Abstract The Van Allen radiation belts contain relativistic electrons trapped by Earth's magnetic field, posing serious risks to spacecraft. Chorus waves are known to accelerate these electrons via resonant interactions, but these interactions are inherently nonlinear and coherent.

Symmetrization of mathematical model of charge transport in semiconductors
Le Matematiche, 2002 A mathematical model of charge transport in semiconductors is considered. The model is a quasilinear system of differential equations. A problem of finding an additional entropy conservation law and system symmetrization are solved.

On positive weak solutions for a class of weighted (p(.), q(.))−Laplacian systems
Moroccan Journal of Pure and Applied Analysis, 2019 In this paper, we study the existence of positive weak solutions for a quasilinear elliptic system involving weighted (p(.), q(.))−Laplacian operators. The approach is based on sub-supersolutions method and on Schauder’s fixed point theorem.

Boundedness in a quasilinear 2D parabolic-parabolic attraction-repulsion chemotaxis system
, 2016 In this paper, we consider the following quasilinear attraction-repulsion chemotaxis system of parabolic-parabolic type \begin{equation*} \left\{ \begin{split} &u_t=\nabla\cdot(D(u)\nabla u)-\nabla\cdot(\chi u\nabla v)+\nabla\cdot(\xi u\nabla w ...
