Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Asymmetric Information With Multiple Risks: The Case of the Chilean Private Health Insurance Market

open access: yesHealth Economics, EarlyView.
ABSTRACT We extend the Rothshild and Stiglitz (1976) model to two sources of risk –inpatient and outpatient risk– to better proxy real‐world health insurance markets. We uncover an interesting theoretical possibility: Take individuals A and B, who are low risks in, say, the inpatient dimension but A is riskier in the outpatient dimension.

Asymptotics for the Spectrum of the Laplacian in Thin Bars with Varying Cross Sections

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider spectral problems for the Laplace operator in 3D rod structures with a small cross section of diameter O(ε)$$ O\left(\varepsilon \right) $$, ε$$ \varepsilon $$ being a positive parameter. The boundary conditions are Dirichlet (Neumann, respectively) on the bases of this structure, and Neumann on the lateral boundary.
