von Willebrand disease (VWD), the most common inherited bleeding disorder, is very heterogeneous, both in its phenotype and genotype. One particular molecular mechanism of VWD is due to recombination events between the true gene and its pseudogene on chromosome 22. We assessed the frequency and extension of such events in 50 multi-ethnic index patients with… (More)
Experimental investigations of synchronization and anti-synchronization of optically coupled semiconductor lasers with external cavities are presented. Both lasers show chaotic low-frequency intensity fluctuations that are (anti-) synchronized due to optical coupling by light injection. For uni-directional coupling response lasers with and without external… (More)
Experimental observations and numerical simulations of synchronization and antisynchronization of low-frequency power drop-outs and jump-ups of chaotic semiconductor lasers are presented.
It is shown that phase synchronization of chaotic dynamical systems can be achieved using a binary coupling signal that takes only two possible values. This phenomenon is demonstrated using analog electronic implementations of the Rössler system and Chua's oscillator.
A short exposure of cell suspensions to gaseous hydrogen sulfide, appropriate fixations, and subsequent physical development of silver shells around sulfidated insoluble metals were used to amplify ferritin iron cores in blood and bone marrow cells. The methods described are suitable for both light microscopy and transmission electron microscopy. These… (More)
Experimental investigations and simulations of synchronization phenomena of individual longitudinal optical modes of unidirectionally light injection coupled semiconductor lasers are presented and compared with the (anti-)synchronization of the corresponding full intensity fluctuations.
