This paper is concerned with the existence of contact structures on (connected, closed, orientable) 5-manifolds with certain finite fundamental groups. As such, it constitutes a sequel to [6] (which gave corresponding existence results for highly connected manifolds of arbitrary (odd) dimension and some ad hoc results for finite fundamental groups) and our joint paper [7], where we showed that ...

We experimentally study the phase behaviour of a charge-stabilized two-dimensional colloidal monolayer which is subjected to a one-dimensional quasiperiodic substrate potential. Upon increasing the laser intensity, we observe a transition from a periodic to a quasiperiodic state. It proceeds via the formation of an intermediate periodic average structure (PAS) which is related to the quasiperio...

Spontaneously evolving Turing structures in the chlorine dioxide-iodine-malonic acid reaction-diffusion system typically exhibit many defects that break the symmetry of the pattern. Periodic spatial forcing interacts with the Turing structures and modifies the pattern symmetry and wavelength. We investigate the role of the amplitude and wavelength of spatial periodic forcing on the hexagonal pa...

Due to the need for higher reliability and performance from RF circuits, multi-port reflectometers are increasingly used as low-overhead impedance monitors. In this work, using periodic structures multi-ports is proposed. Periodic impose a new constraint on theory simplify it significantly. This simplification leads closed form solution calibration measurement procedures. The closed-form also s...
