Inverse problem of determining the coefficients in a degenerate parabolic equation
Electronic Journal of Differential Equations, 2014 We consider the inverse problem of identifying the time-dependent coefficients in a degenerate parabolic equation. The conditions of existence and uniqueness of the classical solution to this problem are established. We investigate the case of weak

Stackelberg strategy on a degenerate parabolic equation with missing data
, 2022 This paper deals with the hierarchic control of a degenerate parabolic equation with missing initial condition. We present a Stackelberg strategy combining the concept of null controllability with low-regret control.

Physics‐Based Compact Modeling of Advanced 3D Nanoscale Vertical NAND Flash Memory
Advanced Electronic Materials, EarlyView.For advanced 3D NAND flash memory, a unified compact model for SPICE is proposed that spans from the intrinsic unit cell to the full string and captures the electrostatic coupling with adjacent inhibit strings. It can successfully predict read behavior, program/erase dynamics, and interactions between neighboring cells, reflecting array‐level behavior ...

The Properties of the Solution to Some Degenerate Parabolic Equation
, 2006 摘要: 对一类具有扰动项的退化抛物方程,考虑其解的性质. 即证明扰动问题的解的极限(ε→0) 是不含扰动项的退化抛物 方程的解. 本文是先把具扰动项的退化抛物方程正则化,然后证明正则化问题的解的HÊl der 连续性以及满足的两个不等 式,由正则化问题解的性质得到原退化抛物方程的解的性质,最后证明ε→0 时解的极限性质.

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2
Advanced Electronic Materials, EarlyView.ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\

Controllability of nonlinear degenerate parabolic cascade systems
Electronic Journal of Differential Equations, 2016 This article studies of null controllability property of nonlinear coupled one dimensional degenerate parabolic equations. These equations form a cascade system, that is, the solution of the first equation acts as a control in the second equation and

On an Anisotropic Parabolic Equation on the Domain with a Disjoint Boundary
Journal of Function Spaces, 2018 Consider the anisotropic parabolic equation with the variable exponents vt=∑i=1n(bi(x)vxiqix-2vxi)xi, where bi(x),qi(x)∈C1(Ω¯), qi(x)>1, and bi(x)≥0. If {bi(x)} is not degenerate on Σp⊂∂Ω, a part of the boundary, but is degenerate on the remained part ∂Ω∖
