The purpose of this paper is twofold. Firstly we consider nonlinear nonsmooth elliptic boundary value problems, and also related parabolic initial boundary value problems that model in a simplified way steady-state unilateral contact with Tresca friction

Vulture Exclusion Halves Large Carcass Decomposition Rates and Doubles Fly Abundance
We experimentally excluded vultures from pig carcasses (Sus scrofa) in Costa Rica, under different habitats and across seasons with the aim to assess the impact of vulture population decline on carrion decomposition and insect abundance. Vulture exclusion halved carcass decomposition rates and doubled fly abundance, while dung beetle abundance remained

We consider a one‐dimensional Allen‐Cahn equation with constraint from the viewpoint of numerical analysis. The constraint is provided by the subdifferential of the indicator function on the closed interval, which is the multivalued function. Therefore, it is very difficult to perform a numerical experiment of our equation. In this paper we approximate

This paper addresses the problem of a 500‐kV main grid partition planning by proposing a partition method based on complex network theory and an improved multi‐objective cuckoo search optimisation (MOCSO) algorithm to achieve grid optimal partition and the generation of key channel set.

On the Convergence of Solutions for SPDEs under Perturbation of the Domain
We investigate the effect of domain perturbation on the behavior of mild solutions for a class of semilinear stochastic partial differential equations subject to the Dirichlet boundary condition. Under some assumptions, we obtain an estimate for the mild solutions under changes of the domain.

The digitalization of family life: A multilevel conceptual framework
Abstract The internet and digital technologies have penetrated all domains of people's lives, and family life is no exception. Despite being a characterizing feature of contemporary family change, the digitalization of family life has yet to be systematically theorized.

Semilinear Evolution Problems with Ventcel‐Type Conditions on Fractal Boundaries
A semilinear parabolic transmission problem with Ventcel′s boundary conditions on a fractal interface S or the corresponding prefractal interface Sh is studied. Regularity results for the solution in both cases are proved. The asymptotic behaviour of the solutions of the approximating problems to the solution of limit fractal problem is analyzed.

Quasi‐conical domains with embedded eigenvalues
Abstract The spectrum of the Dirichlet Laplacian on any quasi‐conical open set coincides with the non‐negative semi‐axis. We show that there is a connected quasi‐conical open set such that the respective Dirichlet Laplacian has a positive (embedded) eigenvalue.

Lower Convergence of Minimal Sets in Star‐Shaped Vector Optimization Problems
Let {An} be a sequence of nonempty star‐shaped sets. By using generalized domination property, we study the lower convergence of minimal sets Min An. The distinguishing feature of our results lies in disuse of convexity assumptions (only using star‐shapedness).

We define the concept of energy‐variational solutions for the Navier–Stokes and Euler equations and prove their existence in any space dimension. It is shown that the concept of energy‐variational solutions enjoys several desirable properties. Energy‐variational solutions are not only known to exist and coincide with local strong solutions, but the ...
