Born expansion of the Casimir-Polder interaction of a ground-state atom with dielectric bodies
Stefan Yoshi Buhmann, Dirk-Gunnar Welsch
Within leading-order perturbation theory, the Casimir-Polder potential of a ground-state atom placed within an arbitrary arrangement of dispersing and absorbing linear bodies can b…
On de Sitter Vacua in Type IIA Orientifold Compactifications
Frank Saueressig, Ulrich Theis, Stefan Vandoren
This letter discusses the orientifold projection of the quantum corrections to type IIA strings compactified on rigid Calabi-Yau threefolds. It is shown that N=2 membrane instanton…
Gl86B: a white dwarf orbits an exoplanet host star
M. Mugrauer, R. Neuhaeuser
In this letter we present our first high contrast NACO/SDI observations of the exoplanet host star Gl86 and results from NACO spectroscopy. Els et al. (2001) found a faint co-movin…
Membrane Instantons and de Sitter Vacua
Marijn Davidse, Frank Saueressig, Ulrich Theis +1
We investigate membrane instanton effects in type IIA strings compactified on rigid Calabi-Yau manifolds. These effects contribute to the low-energy effective action of the univers…
The Combined Technique for Detection of Artifacts in Clinical Electroencephalograms of Sleeping Newborns
Vitaly Schetinin, Joachim Schult
In this paper we describe a new method combining the polynomial neural network and decision tree techniques in order to derive comprehensible classification rules from clinical ele…
A Neural-Network Technique to Learn Concepts from Electroencephalograms
Vitaly Schetinin, Joachim Schult
A new technique is presented developed to learn multi-class concepts from clinical electroencephalograms. A desired concept is represented as a neuronal computational model consist…
