Positive solutions for superlinear elliptic equations [PDF]
The existence of a positive, radial solution for superlinear elliptic boundary value problem in an exterior domain is proved, by the use of cone expansion fixed point ...

Local ‘Superlinearity’ and ‘Sublinearity’ for the p-Laplacian
The authors obtain existence and multiplicity results for the parametric Dirichlet problem \(\Delta_p u+f_\lambda (x,u)=0\) set in a bounded domain, both in the subcritical and critical cases. Also, as a by product, some improved strong comparison principles and \(C^{1,\alpha}\) estimates are given.

Optimal subsampling for regression with mixed‐type predictors
Abstract Subsampling has emerged as an appealing strategy to mitigate the computational and storage challenges imposed by large datasets. Recent subsampling techniques have shown notable computational gains for data dominated by numerical predictors. However, real‐world datasets frequently contain both numerical and categorical predictors.

Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...
