Quasilinear problems with two parameters including superlinear and gradient terms
Electronic Journal of Differential Equations, 2014 In this article, we establish conditions for the existence of solutions for a quasilinear elliptic two-parameter problem with dependence on the gradient term in smooth bounded domains or in the whole space R^N.

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer
Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Nanophotonics, Volume 15, Issue 17, 11 September 2026.A quantum‐coherent density‐matrix study reveals a predominantly cumulative thermo‐optic nonlinear response in ITO under extremely short pulses, with coherent electron dynamics leaving signatures in macroscopic polarization and permittivity. Remarkably, the permittivity dynamics are accurately reproduced by a simple thermal model. We also generalize the

Superlinear threshold detectors in quantum cryptography
, 2011 We introduce the concept of a superlinear threshold detector, a detector that has a higher probability to detect multiple photons if it receives them simultaneously rather than at separate times.

Characterizing the formation of singularities in a superlinear indefinite problem related to the mean curvature operator [PDF]
, 2020 The aim of this paper is characterizing the development of singularities by the positive solutions of the quasilinear indefinite Neumann problem egin{equation*} label{P} -(u'/sqrt{1+(u')^2})' = lambda a(x) f(u) ; ; ext{in } (0,1), quad u'(0)=0,;u'(1)=0 ...

Electronic Journal of Differential Equations, 2018 In this article we prove the existence of an infinite number of radial solutions to $\Delta u+K(r)f(u)=0$ with a nonlinear boundary condition on the exterior of the ball of radius R centered at the origin in $\mathbb{R}^{N}$ such that $\lim_{r \to ...

Periodic Solutions of a Class of Fourth-Order Superlinear Differential Equations
Abstract and Applied Analysis, 2012 This paper deals with the periodic solutions of a class of fourth-order superlinear differential equations. By using the classical variational techniques and symmetric mountain pass lemma, the periodic solutions of a single equation in literature are ...

Advanced Materials, Volume 38, Issue 52, 16 September 2026.This work investigates the heterogeneous nucleation of CsPbBr3${\rm CsPbBr}_3$ nanocrystal superlattices along the faces of 2D PEA2PbBr4${\rm PEA}_2{\rm PbBr}_4$ layered perovskite microcrystals. Core–crown and core–shell heterostructure morphologies are obtained.
