Evaluation of Resorcinarene Trimer Methanesulfonate Aggregation in the Presence of Inorganic Salts and Biomolecules in Aqueous Solutions Using UV–vis Spectroscopy and Electrophoresis

ChemPhysChem, Volume 27, Issue 9, 14 May 2026.
UV–vis spectra of resorcinarene trimer methanesulfonate were identified in the presence of inorganic salts, choline, and bovine serum albumin. The origin of the peaks was identified. The absorption dynamic over the course of 5 days revealed that Na+ cations promote supramolecular aggregation while choline hinders it.

Image restoration using a reaction-diffusion process

Electronic Journal of Differential Equations, 2014
This study shows how partial differential equations can be employed to restore a digital image. It is in fact a generalization of the work presented by Catte [12], which modify the Perona-Malik Model by nonlinear diffusion.

A new quasilinear formulation for ICRF plasmas in a toroidal geometry

EPJ Web of Conferences, 2017
We present a new formulation for quasilinear velocity space diffusion for ICRF plasmas that considers two different aspects: (1) finite Larmor radius approximation and (2) includes the effect of toroidal geometry and constructs a positive definite form ...

Nonlinear models of wave processes in the dimension (1 + 1) and first order quasilinear equations

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023
Background. The study considers the connection of models of nonlinear wave processes in various one-dimensional physical systems, such as nonlinear two-wire lines, with first order quasilinear equations.

Ground state solutions for the asymptotically periodic Schrödinger–Poisson systems with $p$-Laplacian

Electronic Journal of Qualitative Theory of Differential Equations
In this paper we study the existence of ground state solutions for the asymptotically periodic Schrödinger–Poisson systems which are coupled by a Schrödinger equation of $p$-Laplacian and a Poisson equation of $q$-Laplacian.

Diffusion Coefficients for Resonant Relativistic Wave‐Particle Interactions Using the PIRAN Code

Earth and Space Science
Quasilinear diffusion coefficients can be used to model the response of charged particles to resonant wave‐particle interactions. The calculation of these coefficients is sufficiently complicated and arduous to render it prohibitive to many potential ...

Global boundedness and stability of a quasilinear two-species chemotaxis-competition model with nonlinear sensitivities

Advances in Nonlinear Analysis
This study deals with the global boundedness of a classical solution to a quasilinear two-species chemotaxis-competition model with nonlinear sensitivities in n≤3n\le 3. Due to the presence of nonlinear sensitivities, obtaining the necessary ‖w‖L∞\Vert w{
