Evaluation of Resorcinarene Trimer Methanesulfonate Aggregation in the Presence of Inorganic Salts and Biomolecules in Aqueous Solutions Using UV-vis Spectroscopy and Electrophoresis. [PDF]

Chemphyschem
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.

Hamiltonian formulations of quasilinear theory for magnetized plasmas

Frontiers in Astronomy and Space Sciences, 2022
Hamiltonian formulations of quasilinear theory are presented for the cases of uniform and nonuniform magnetized plasmas. First, the standard quasilinear theory of Kennel and Engelmann (Kennel, Phys. Fluids, 1966, 9, 2377) is reviewed and reinterpreted in

Weighted $L^p$-type regularity estimates for nonlinear parabolic equations with Orlicz growth

Electronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper we obtain the following weighted $L^p$-type regularity estimates $$ B\left(\left|\mathbf{f}\right|\right)\in L^{q}\left(\nu, \nu+T; L^q_w(\Omega) \right) \ \mbox{locally} \Rightarrow B\left(\left|\nabla u\right|\right)\in L^{q}\left ...

Comparison of Saturation Rules Used for Gyrokinetic Quasilinear Transport Modeling

Plasma, 2023
Theory-based transport modeling has been widely successful and is built on the foundations of quasilinear theory. Specifically, the quasilinear expression of the flux can be used in combination with a saturation rule for the toroidal mode amplitude. Most

Temporal variability of quasi-linear pitch-angle diffusion

Frontiers in Astronomy and Space Sciences, 2022
Kinetic wave-particle interactions in Earth’s outer radiation belt energize and scatter high-energy electrons, playing an important role in the dynamic variation of the extent and intensity of the outer belt.

Improved Hille-Type Oscillation Criteria for Second-Order Quasilinear Dynamic Equations

Mathematics, 2022
In this work, we develop enhanced Hille-type oscillation conditions for arbitrary-time, second-order quasilinear functional dynamic equations. These findings extend and improve previous research that has been published in the literature.

On Soft Normed Quasilinear Spaces

Journal of New Theory, 2023
In this study, we investigate some properties of soft quasi-sequences and present new results. We then study the completeness of soft normed quasilinear space and present an analog of convergence and boundness results of soft quasi sequences in soft ...

Nonpolynomial B-spline collocation method for solving singularly perturbed quasilinear Sobolev equation [PDF]

Iranian Journal of Numerical Analysis and Optimization
In this paper, a singularly perturbed one-dimensional initial boundary value problem of a quasilinear Sobolev-type equation is presented. The nonlinear term of the problem is linearized by Newton’s linearization method.

Oscillation Criteria for Qusilinear Even-Order Differential Equations

Mathematics, 2023
In this study, we extended and improved the oscillation criteria previously established for second-order differential equations to even-order differential equations. Some examples are given to demonstrate the significance of the results accomplished.

Butterfly support for off diagonal coefficients and boundedness of solutions to quasilinear elliptic systems

Advances in Nonlinear Analysis, 2021
We consider quasilinear elliptic systems in divergence form. In general, we cannot expect that weak solutions are locally bounded because of De Giorgi’s counterexample. Here we assume that off-diagonal coefficients have a “butterfly support”: this allows
