Mixed-Potential Integral Equation for Full-Wave Modeling of Grounding Systems Buried in a Lossy Multilayer Stratified Ground

Farhad Rachidi-Haeri, Hamidreza Karami, Keyhan Sheshyekani

The paperpresents a comprehensive approach for full-wave modeling of grounding systems buried in a multilayer stratified ground. The dyadic spectral domain Green's function associated with the multilayer stratified ground is first derived. This Green's fun ...

EEG frequency tagging dissociates target and flanker processing in crowding

Michael Herzog, Vitaly Chicherov

Flankers can strongly deteriorate performance on a target (crowding). The neural mechanisms of crowding are largely unknown. We have recently shown that the N1 component of the EEG is suppressed during crowding. Because it is difficult to disentangle the n ...

Spectral cola or how to turn green laser light red

Thibaud Humair, Xavier François Mettan, Csaba Forro

A green laser pointer shone through a glass of cola will appear red when looking from above the glass. Lowering the laser so that it is deeper in the cola, the colour will vary from orange to deep red. Fluorescence and absorption spectra were recorded cons ...

L (p) error estimates for approximation by Sobolev splines and Wendland functions on a"e (d)

John Paul Ward

It is known that a Green's function-type condition may be used to derive rates for approximation by radial basis functions (RBFs). In this paper, we introduce a method for obtaining rates for approximation by functions which can be convolved with a finite ...

The temporal dynamics of feature integration for color and form

Michael Herzog

When two visual stimuli are presented in rapid succession only one fused image is perceived. For example, a red disk followed by a green disk is perceived as a single yellow disk (e.g., Efron, Perc Psychophys, 1973). For two verniers that last 30ms each, i ...

Comment on 'An analytic solution of capillary rise restrained by gravity' by N. Fries and M. Dreyer

David Andrew Barry, Laurin Wissmeier

The porous medium model of Green and Ampt, describing flow in porous media, appeared earlier than the capillary model of Washburn, although both lead to the mathematically identical models. The model of Green and Ampt is related to the Washburn model by an ...

'I pay enough taxes already!' Applying economic voting models to environmental referendums

Philippe Thalmann, Nicholas Bornstein

Objectives. Models of economic voting have rarely been applied to referendum votes. We fill this gap by testing citizens’ voting behavior on environmental policy in relation to their perception of the business cycle. Thus, the study examines the personal, ...

One-Step Conversion of Cellobiose to C6-Alcohols Using a Ruthenium Nanocluster Catalyst

Paul Joseph Dyson, Ning Yan, Cheng Zhao, Huizhen Liu

The one-step conversion of cellulose to C6-alcs. via green and energy efficient approaches has, as far as we are aware, not been reported. Such a process presents a considerable challenge, the two key problems being (1) finding a suitable solvent that diss ...

Numerical modeling of planar periodic structures in electromagnetics

Katarina Blagovic

Periodic structures, such as frequency-selective surfaces (FSSs) and photonic band-gap (PBG) materials, exhibit total reflection in specific frequency bands while total transmission in other bands. They find numerous applications in a large field of the el ...
