A range of mesogenic molecules varying in both bend angle and strength of lateral dipole were synthesized, and their phase behavior was characterized by polarizing microscopy, thermal analysis, X-ray diffraction, and electrooptical measurements. We find the general destabilization of the liquid crystallinity caused by strong lateral dipolar groups and the bent molecular shape are off-set in mes...

The effect of hydrodynamic coupling on the spatial orientation of rigid bent rods in electric fields has been analyzed by Brownian dynamics simulations. Bead models for smoothly bent rods were constructed with dimensions of DNA double helices, and established simulation procedures were used to calculate their diffusion tensor, including the translational-rotational coupling tensor. The electric...

The Laser Applications at Accelerators network (LA3NET) is a pan-European project that has received 4.6 M€ of funding from the European Union's 7th Framework Programme. It closely links research into lasers and accelerators to develop advanced particle sources, new accelerating schemes, and in particular beyond state-ofthe-art beam diagnostics. This contribution summarizes the research achievem...

In this article we consider a path planning problem for a single fixed-wing aircraft performing an ISR (Intelligence Surveillance Reconnaissance) mission using EO (ElectroOptical) camera(s). We give a mathematical formulation of the general aircraft visual reconnaissance problem for static ground targets in terrain and show that, under simplifying assumptions, it can be reduced to a variant of ...

To monitor conformational changes of individual membrane transporters in liposomes in real time, we attach two fluorophores to selected domains of a protein. Sequential distance changes between the dyes are recorded and analyzed by Förster resonance energy transfer (FRET). Using freely diffusing membrane proteins reconstituted in liposomes, observation times are limited by Brownian motion throu...
