Sensitivity of Pareto Solutions in Multiobjective Optimization. [PDF]
The paper presents a sensitivity analysis of Pareto solutions on the basis of the Karush-Kuhn-Tucker (KKT) necessary conditions applied to nonlinear multiobjective programs (MOP) continuously depending on a parameter.

Asymptotically radial solutions in expanding annular domains [PDF]
, 2011 In this paper we consider the problem where p > 1 and Ω R is a smooth bounded domain with a hole which is diffeomorphic to an annulus and expands asR → ∞.

Nonexistence of radial entire solutions of elliptic systems
Journal of Differential Equations, 2003 The author considers the quasi-variational ordinary differential system \[ [\nabla G(u,u')]'- \nabla_u G(u,u')+ Q(t, u,u')= f(t,u) \] on \(J= (T,\infty)\), \(T\geq 0\), where \(\nabla= \nabla_u\) denotes the gradient operator with respect to the second variable of the function \(G\).

Radial solutions for the bilaplacian equation with vanishing or singular radial potentials
, 2018 Given three measurable functions $V\left(r \right)\geq 0$, $K\left(r\right)> 0$ and $Q\left(r \right)\geq 0$, $r>0$, we consider the bilaplacian equation \[ Δ^2 u+V(|x|)u=K(|x|)f(u)+Q(|x|) \quad \text{in }\,\mathbb{R}^N \] and we find radial solutions thanks to compact embeddings of radial spaces of Sobolev functions into sum of weighted Lebesgue

Advanced Engineering Materials, EarlyView.A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

A Note on nonexistence of radial solutions to semilinear elliptic inequations [PDF]
, 2002 We study the nonexistence result of radial solutions to -[Delta]u + [formula] posed in B or in B \ {0} where B is the unit ball centered at the origin in RN, N [greater than or equal] 3.

Bounded and large radially symmetric solutions for some (p,q)-Laplacian stationary systems
Electronic Journal of Differential Equations, 2012 This article concerns radially symmetric positive solutions of second-order quasilinear elliptic systems. In terms of the growth of the variable potential functions, we establish conditions such that the solutions are either bounded or blow up at ...

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...
