The Goursat problem for hyperbolic linear third order equations
Mathematical Modelling and Analysis, 2001 The third order hyperbolic linear differential equation is considered in the non‐cylindrical domain of multidimensional Euclidean space. The equation operator is a composition of a differentiation operator of the first order and second order operator ...

On the Navier-Stokes equations in non-cylindrical domains: On the existence and regularity
Mathematische Zeitschrift, 1988 We consider the motion of a viscous incompressible fluid in a container with moving walls, in other words we have to deal not with a space-time cylinder but with a non-cylinder domain in \({\mathbb{R}}^ 3\times [0,T]\). To be more precise, we consider a domain \[ \Omega_ T=\cup_{0\leq t\leq T}\Omega (t)x\{t\}, \] where each \(\Omega\) (t) is a bounded ...

Advanced Functional Materials, EarlyView.A biomimetic aerogel conduit was engineered from a nanofiber of gelatin/poly(l‐lactic acid) doped with polypyrrole nanoparticles, integrated with tannic acid and Mg2+. This “electro‐ionic‐immune” strategy mimicked spinal cord properties, reduced calcium overload, inflammation, oxidative damage, promoted neural stem cell differentiation, suppressed ...

Stacking Fault Complexions in AgSbTe2 Thermoelectrics With Enhanced Electrical Conductivity
Advanced Functional Materials, EarlyView.Atomic‐scale characterization resolves stacking fault complexion in AgSbTe2, showing Te and Sb segregation along with lattice dilation. Their enhanced effects on phonon scattering are modeled analytically. Although most defects also impede electron transport, local four‐point‐probe measurements reveal higher electrical conductivity at stacking fault ...
