Lower bounds for solutions of degenerate parabolic equations.
, 2007 We show how pointwise lower bounds for positive weak solutions of degenerate parabolic equations can be derived from the intrinsic Harnack inequality they satisfy.

Regularity of random attractors for stochastic semilinear degenerate parabolic equations
Electronic Journal of Differential Equations, 2012 We consider the stochastic semilinear degenerate parabolic equation $$ du+[- operatorname{div}(sigma(x)abla u) + f(u) + lambda u]dt = gdt+ sum_{j=1}^{m}h_j{domega_j} $$ in a bounded domain $mathcal{O}subset mathbb {R}^N$, with the nonlinearity ...

Cauchy-Dirichlet problem for the nonlinear degenerate parabolic equations
Abstract and Applied Analysis, 2005 We will investigate the nonexistence of positive solutions for the following nonlinear parabolic partial differential equation: ∂u/∂t=ℒu+V(w)up−1 in Ω×(0,T ...

Ab Initio Thermoelectric Transport Calculations of Alloyed Half‐Heuslers
Advanced Science, EarlyView.The effect of alloying on the electronic transport of half‐Heusler thermoelectric materials is explored using a fully ab initio approach. A novel method is developed that combines calculations of alloyed supercells with Boltzmann transport, considering the full energy and momentum dependent scattering processes from first principles extracted ...

Coordinated Electronic‐Transport Regulation and Multiscale Phonon Scattering in Sb–La Co‐Doped GeTe
Advanced Science, EarlyView.Synergistic Sb–La co‐doping simultaneously regulates hole concentration and creates strain‐field fluctuations and multiscale structural disorder in GeTe. Electrical transport is preserved, while electronic and lattice thermal conductivities are strongly suppressed.

Electronic Journal of Differential Equations, 2005 We consider degenerate parabolic and elliptic equations of second order with $C^1$ and $C^2$ coefficients. Error bounds for certain types of finite-difference schemes are obtained.

Advanced Science, EarlyView.A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Experiments on Nonlocal Fluid‐Flow Metamaterials
Advanced Science, EarlyView.A nonlocal fluid‐flow metamaterial composed of standard microfluidic tubes and connectors is designed. Hence, the current of the system at one position depends on the gradient of fluid flow at many other positions, leading to unusual alternating backward and forward laminar flows of water.
