Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites

Advanced Functional Materials, EarlyView.
A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...

On uniqueness for nonlinear elliptic equation involving the Pucci's extremal operator [PDF]

, 2006
In this article we study uniqueness of positive solutions for the nonlinear uniformly elliptic equation M-lambda(+),(Lambda)(D(2)u) - u + u(P) = 0 in R-N, lim(r ->infinity) u(r) = 0, where M-lambda(,Lambda)+ (D(2)u) denotes the Pucci's extremal operator ...

Nonlinear Ritz approximation for Fredholm functionals

Electronic Journal of Differential Equations, 2015
In this article we use the modify Lyapunov-Schmidt reduction to find nonlinear Ritz approximation for a Fredholm functional. This functional corresponds to a nonlinear Fredholm operator defined by a nonlinear fourth-order differential equation.

A Nonlinear Schrödinger Equation Resonating at an Essential Spectrum

Advances in Mathematical Physics, 2016
We consider the nonlinear Schrödinger equation -Δu+f(u)=V(x)u  in  RN. The potential function V satisfies that the essential spectrum of the Schrödinger operator -Δ-V is [0,+∞) and this Schrödinger operator has infinitely many negative eigenvalues ...

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced 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.

A Scattering Operator for Some Nonlinear Elliptic Equations

Archive for Rational Mechanics and Analysis
We consider non linear elliptic equations of the form $Δu = f(u,\nabla u)$ for suitable analytic nonlinearity $f$, in the vinicity of infinity in $\mathbb{R}^d$, that is on the complement of a compact set.We show that there is a \emph{one-to-one correspondence} between the non linear solution $u$ defined there, and the linear solution $u\_L$ to the ...
