Regularity Estimates for Fully Nonlinear Dead‐Core Problems With a Hamiltonian Term

Mathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we present a problem involving fully nonlinear elliptic operators with Hamiltonian, which can present a singularity or degenerate as the gradient approaches the origin. The model studied here, allows the appearance of plateau zones, i.e., unknown regions of the domain in which the non‐negative solutions vanishes.

Optimization problems on the Sierpinski gasket

Electronic Journal of Differential Equations, 2016
We investigate the existence of an optimal process for such an optimal control problem in which the dynamics is given by the Dirichlet problem driven by weak Laplacian on the Sierpinski gasket.

When Connection Feels Empty: Rethinking Consumer Loneliness Through Dual Presence in Digital Marketing

Psychology &Marketing, EarlyView.
ABSTRACT Digital marketplaces sell connection, yet loneliness persists among their users. Marketing scholarship has largely examined loneliness as a consumer‐level deficit, studying how individuals compensate through consumption. How digital environments themselves structure the conditions under which loneliness is experienced has received less ...

Optimal Design of Elastic Plates: Hybrid Numerical Method Based on Homogenization and Shape Derivative

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper focuses on optimal design problems in the context of the Kirchhoff‐Love model for pure bending of a thin, solid, symmetric plate under a transverse load. The objective is to simultaneously determine the optimal outer shape of the domain and the distribution of two isotropic materials within the domain in order to minimize compliance.

A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

Business‐Like Narrative and Public Engagement: Evidence From TED Talks on Nonprofit Issues

Nonprofit Management and Leadership, EarlyView.
ABSTRACT While the trend of nonprofits adopting business‐like practices has been widely discussed, limited attention has been paid to how the broader public responds to this shift. One way to capture public reactions is by examining engagement with business‐like narratives in media.

Asymmetric transferability of trait–environment relationships between native and exotic plant species in Singaporean forests differing in land‐use history

Oikos, EarlyView.
Functional traits allow ecologists to synthesise general rules of community assembly. In joint species distribution modelling, traits are increasingly used to explain species–environment relationships, with the intention of being able to generalise predictions to other species in other systems.
