Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Estimating the Share and Elasticity of Substitution for Public and Private Health Expenditures in Iran

open access: yesRāhburdhā-yi Mudīriyyat dar Niẓām-i Salāmat, 2020
Background: The rate of substitution for private and public health expenditures is one of the factors that can explain the different effects of public and private health expenditures on health and life expectancy. Therefore, the purpose of this study was

Connecting Euler and Lagrange systems as nonlocally related systems of dynamical nonlinear elasticity

open access: yesArchives of Mechanics, 2011
Nonlocally related systems for the Euler and Lagrange systems of two-dimensional dynamical nonlinear elasticity are constructed. Using the continuity equation, i.e., conservation of mass of the Euler system to represent the density and Eulerian velocity ...

Genipin‐Crosslinked, Silane‐Anchored 3D Tumor–Stroma Microtissues for High‐Content On‐Chip Drug Testing

open access: yesAdvanced Healthcare Materials, EarlyView.
We describe a microfluidic tumor‐stroma co‐culture model, engineered to resist collagen‐hydrogel contraction driven by fibroblast activity. Surface silanization with APTES covalently anchors the matrix to the chip, while Genipin crosslinking progressively increases stiffness and elasticity without harming cells. This supports >10 days of co‐culture and
