Generalized Blocks of Unipotent Characters in the Finite General Linear Group

In an article of 2003, Kulshammer, Olsson, and Robinson defined l-blocks for the symmetric groups, where l is an arbitrary integer, and proved that they satisfy an analogue of the Nakayama Conjecture. Inspired by this work and the definitions of generalize ...

Electrostatic turbulent structures in TORPEX plasmas

Christian Gabriel Theiler

Experimental data from many Tokamaks suggest that an important fraction of radial particle and heat transport in the Scrape-Off-Layer is due to poloidally-localized propagating structures of increased plasma density (blobs). A better understanding of the m ...

Sol-gel deposition and characterization of low refractive index nanocomposite Mg:F:Si:O thin films for solar and protective coatings

Jean-Louis Scartezzini, Christian Roecker, Josef Andreas Schuler, Estelle De Chambrier, Dipanwita Dutta

Coatings for thermal solar energy conversion have to be abrasion-resistant, stable at elevated temperatures, and often have to protect the substrate against corrosion. Due to the conditions of refractive index matching between the substrate and the ambient ...

New synthetic route toward polyketide-like macrolides

Sandrine Gerber, Gérald Coste

New pathways toward the synthesis of polyketide-like macrolides have been developed through the functionalization of long chain polyolic fragments readily obtained from 3,3'-methylenebis{[6-(benzyloxy)methoxy]cyclohept-3-en-1-ol} derivatives 6. This synthe ...

Constraints for the existence of flat and stable non-supersymmetric vacua in supergravity

Claudio Scrucca

We further develop on the study of the conditions for the existence of locally stable non-supersymmetric vacua with vanishing cosmological constant in supergravity models involving only chiral super fields. Starting from the two necessary conditions for fl ...

Asymmetric synthesis of the polyol subunit of the polyene macrolide antibiotic RK-397

Pierre Vogel, Sandrine Gerber, Kai Torsten Meilert

A total asymmetric synthesis of the polyol subunit of the polyene macrolide antibiotic RK-397 was developed through the stereoselective functionalization of (1R,1’S,6S,6’R)-3,3’-methylenebis(cyclohept-3-ene-1,6-diol). The pathway generates a large variety ...

Efficient implementation of the integral equation technique with the method of moments

Michael Mattes

Analysing and optimising electromagnetic structures like filters, multiplexers, printed circuits and antennas etc. demand for electromagnetic CAD tools to be accurate and fast at the same time. In very rare cases a closed form (approximate) solution of the ...

Digital Holographic Microscopy (DHM): Fast and robust 3D measurements with interferometric resolution for industrial inspection

Christian Depeursinge, Etienne Cuche, Nicolas Aspert, Pierre Marquet, Jonas Kühn, Stéphane Bourquin

The use of numerical procedure at a level never reach so far in optical imaging enables DHM to overcome two cumbersome alignment procedures of interferometric microscopes: (1) fine focus of the sample, and (2) sample tilt adjustment. In addition the techno ...

Real-time navigating crowds: Scalable simulation and rendering

Daniel Thalmann, Jonathan Maim, Barbara Yersin

This paper introduces a framework for real-time simulation and rendering of crowds navigating in a virtual environment. The solution first consists in a specific environment preprocessing technique giving rise to navigation graphs, which are then used by t ...
