Direct-Splitting-Based CN-FDTD for Modeling 2D Material Nanostructure Problems

open access: yesIEEE Open Journal of Antennas and Propagation, 2020
Incorporating a truncation of the complex-frequency-shifted perfectly matched layer (CFS-PML), the direct-splitting- based Crank-Nicolson finite-difference time-domain (CNDS-FDTD) is developed and applied to the infrared two-dimensional layered material (

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Geometric and projection effects in Kramers-Moyal analysis

open access: yes, 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

Max Weber on Politics, Reason, and the Clash of Values and Approaches to Ethics [PDF]

open access: yes, 2019
This article investigates how Max Weber’s theory of value conflict is connected to his realist understanding of politics and how he conceives the relation of politics and ethics. This investigation also covers Weber’s views on the argumentative limits of

Self‐Assembled Heterosymmetric Structure with Tunable Polarization Optics for Reversible Matrix Encryption

open access: yesAdvanced Functional Materials, EarlyView.
Sustainable films with heterosymmetric structures, harmoniously integrating symmetry and asymmetry, are fabricated using cellulose nanocrystals and hydrophilic nanolignin via evaporation‐induced self‐assembly, which exhibit excellent multiple polarization optical properties.

Did Philologists write the Iliad? : Friedrich August Wolf's criteria of style and the demonstrative power of citation [PDF]

open access: yes, 2011
Friedrich August Wolf posits in his "Prolegomena ad Homerum" that, from the time of the first transcription of Homer's epics around 700 BC to the time of the Alexandrian editions, the Iliad and Odyssey underwent repeated revisions by a multitude of poets

Stochastic Analysis and Regeneration of Rough Surfaces

open access: yes, 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.

Biofabrication of a Filtration Barrier by Integrating Electrospun Membranes and Flow in a Glomerular Co‐Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
An ex vivo glomerular filtration barrier is engineered using electrospun, biomimetic membranes seeded with human glomerular cells. The model supports fenestrated endothelium and podocyte foot processes under flow, mimics size‐selective filtration, and enables disease modeling with hiPSC‐derived podocytes, offering a powerful platform for studying ...
