Method of lines transpose: High order L-stable O(N) schemes for parabolic equations using successive convolution [PDF]
, 2016 We present a new solver for nonlinear parabolic problems that is L-stable and achieves high order accuracy in space and time. The solver is built by first constructing a single-dimensional heat equation solver that uses fast O(N) convolution.

Evolution operators for higher order abstract parabolic equations [PDF]
Czechoslovak Mathematical Journal, 1986 The author shows the existence of an evolution operator for a higher order abstract parabolic equation with variable coefficients. The techniques employed are similar to Tanabe's method [\textit{H. Tanabe}, Osaka Math. J. 12, 363-376 (1960; Zbl 0098.313)].

Advanced Functional Materials, EarlyView.The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed

Asymptotic expansions of the solutions of the Cauchy problem for nonlinear parabolic equations
, 2012 Let $u$ be a solution of the Cauchy problem for the nonlinear parabolic equation $$ \partial_t u=\Delta u+F(x,t,u,\nabla u) \quad in \quad{\bf R}^N\times(0,\infty), \quad u(x,0)=\varphi(x)\quad in \quad{\bf R}^N, $$ and assume that the solution $u ...

Thermoelasticity and generalized thermoelasticity viewed as wave hierarchies [PDF]
, 2008 It is seen how to write the standard\^E form of the four partial differential equations in four unknowns of anisotropic thermoelasticity as a single equation in one variable, in terms of isothermal and isentropic wave operators.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation
Advanced Functional Materials, EarlyView.A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

Higher-order boundary regularity estimates for nonlocal parabolic equations [PDF]
Calculus of Variations and Partial Differential Equations, 2018 We establish sharp higher-order H lder regularity estimates up to the boundary for solutions to equations of the form $\partial_t u-Lu=f(t,x)$ in $I\times $ where $I\subset\mathbb{R}$, $ \subset\mathbb{R}^n$ and $f$ is H lder continuous. The nonlocal operators $L$ considered are those arising in stochastic processes with jumps such as the ...
