Stochastic Analysis and Regeneration of Rough Surfaces

, 2003
We investigate Markov property of rough surfaces. Using stochastic analysis we characterize the complexity of the surface roughness by means of a Fokker-Planck or Langevin equation.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Of productive germs and the immortal soul : Friedrich Schlegel’s writings on language and early biological theory [PDF]

, 2010
Friedrich Schlegel's lasting contribution to linguistics is usually seen in the impact that his book "Über die Sprache und Weisheit der Indier" from 1808 left on comparative linguistics and on the study of Sanskrit. Schlegel was one of the first European

Geometric and projection effects in Kramers-Moyal analysis

, 2009
Kramers-Moyal coefficients provide a simple and easily visualized method with which to analyze stochastic time series, particularly nonlinear ones. One mechanism that can affect the estimation of the coefficients is geometric projection effects. For some
